Definitions

  • the disclosed and claimed concept relates to training weights that are structured to be, and are, coupled to sports equipment.
  • Training weights used with sports equipment are known in a number of different sports.
  • a toroid, i.e., ring-shaped, weight used with baseball bats are a familiar example.
  • baseball bats have a grip with a relatively small diameter, a taper that increases the diameter, and a barrel that has a greater diameter relative to the grip.
  • a training weight for a baseball bat has an inner diameter that is larger than the grip but smaller than the barrel.
  • the training weight is coupled to the bat by passing the grip through the training weight and moving the training weight toward the barrel until the training weight is snuggly coupled to the baseball bat.
  • the training weight is unlikely to accidentally decouple from the baseball bat. That is, the momentum of the training weight when the baseball bat is in motion biases the training weight toward the end of barrel. As the barrel is wider than the opening in the training weight, the training weight cannot slip off the baseball bat.
  • hockey sticks have a wide, arcuate blade, grip/butt end and shaft therebetween.
  • the grip/butt end in an exemplary embodiment, has a greater cross-sectional area relative to the shaft.
  • a training weight similar to a training weight for a baseball bat is not useful. That is, to pass the grip/butt end, the opening in such a training weight would have a greater cross-sectional area.
  • the grip/butt end has a greater cross-sectional area than the shaft, the opening in such a training weight would also be larger than the shaft cross-sectional area. In this configuration, the training weight would not be snug on the shaft. That is, the training weight could shift up and down the shaft and would likely damage the hockey stick.
  • U.S. Pat. No. 5,520,386 discloses a training weight with an inverted U-shaped body that snuggly fits over the blade as well as a tether.
  • the disadvantage to this configuration is that the training weight covers the blade so that the hockey stick does not properly connect with a puck.
  • the tether is a secure retaining device. That is, the training weight body is able to disengage from the blade and, if the tether fails, the training weight could be thrown through the air. This would be unsafe and is a problem.
  • the training weight devices disclosed in U.S. Pat. Nos. D438,585 and 6,328,666 are spaced from the blade (and therefore do not interfere with the puck), when clamped about the shaft. These devices, however, are secured by threaded fasteners. Such fasteners are time consuming to utilize. Further, the training weight devices may damage the shaft of the hockey stick. Finally, these devices have only the threaded fasteners to retain the training weight device on the hockey stick. That is, there is no additional safety assembly. These are problems.
  • weighted elements that are coupled to a hockey stick by hook-and-loop material. Hook-and-loop material, however, may detach when exposed to impacts and other motions typically experienced by a hockey stick. This is a problem as the training weight device of U.S. Patent Publication No. 2004/0132589 does not have any other retention devices.
  • the training weight device disclosed in U.S. Pat. No. 4,364,560 includes threaded fasteners that engage the shaft as an additional retention device. The fasteners, however, may damage the shaft. These are problems.
  • Still other training weight devices include weights that are disposed within the shaft of the hockey stick. These devices are semi-permanent in that removal of the weights requires disassembly of the sport equipment. That is, they cannot be removed easily. This is also a problem.
  • training weight devices include straps, fasteners and other elements that protrude from the bulk of the training weight device. Such protrusions increase the likelihood of the training weight device interfering with the associated sport. That is, for example, a strap could drag along the ice and interfere with a player's skates.
  • many of the training weight devices noted above are made from a hard material, such as, but not limited to, steel. Such hard materials are likely to scratch or otherwise damage the sport equipment. For example, a training weight device having a generally circular passage which is disposed on a generally cylindrical shaft is likely to rotate about the shaft. When this happens, hard materials defining the passage are likely to scratch or otherwise damage the shaft.
  • a training weight assembly that does not have the problems associated with the prior art training weight devices.
  • a training weight assembly that includes more than two retention devices or assemblies. That is, a training weight device that becomes free during use is dangerous and may injure other people near the user.
  • Known training weight devices are limited to one or two retention devices. This may still be unsafe as, due to the nature of how hockey sticks, or other sport equipment, are used, the retention devices may become unbound or otherwise damaged.
  • the training weight assembly includes a mass assembly and a multi-function retention assembly.
  • the mass assembly is structured to be disposed about the shaft.
  • the multi-function retention assembly is structured to secure the mass assembly about the shaft.
  • FIG. 1 is an isometric view of a user with sports equipment.

  • structured to [verb] means that the identified element or assembly has a structure that is shaped, sized, disposed, coupled and/or configured to perform the identified verb.
  • a member that is “structured to move” is movably coupled to another element and includes elements that cause the member to move or the member is otherwise configured to move in response to other elements or assemblies.
  • structured to [verb] recites structure and not function.
  • structured to [verb] means that the identified element or assembly is intended to, and is designed to, perform the identified verb.
  • an element that is merely capable of performing the identified verb but which is not intended to, and is not designed to, perform the identified verb is not “structured to [verb].”
  • association means that the elements are part of the same assembly and/or operate together, or, act upon/with each other in some manner.
  • an automobile has four tires and four hub caps. While all the elements are coupled as part of the automobile, it is understood that each hubcap is “associated” with a specific tire.
  • a “coupling assembly” includes two or more couplings or coupling components.
  • the components of a coupling or coupling assembly are generally not part of the same element or other component. As such, the components of a “coupling assembly” may not be described at the same time in the following description.
  • a “coupling” or “coupling component(s)” is one or more component(s) of a coupling assembly. That is, a coupling assembly includes at least two components that are structured to be coupled together. It is understood that the components of a coupling assembly are compatible with each other. For example, in a coupling assembly, if one coupling component is a snap socket, the other coupling component is a snap plug, or, if one coupling component is a bolt, then the other coupling component is a nut.
  • a “fastener” is a separate component structured to couple two or more elements.
  • a bolt is a “fastener” but a tongue-and-groove coupling is not a “fastener.” That is, the tongue-and-groove elements are part of the elements being coupled and are not a separate component.
  • two or more parts or components are “coupled” shall mean that the parts are joined or operate together either directly or indirectly, i.e., through one or more intermediate parts or components, so long as a link occurs.
  • directly coupled means that two elements are directly in contact with each other.
  • fixedly coupled or “fixed” means that two components are coupled so as to move as one while maintaining a constant orientation relative to each other. Accordingly, when two elements are coupled, all portions of those elements are coupled.
  • a description, however, of a specific portion of a first element being coupled to a second element, e.g., an axle first end being coupled to a first wheel, means that the specific portion of the first element is disposed closer to the second element than the other portions thereof.
  • an object resting on another object held in place only by gravity is not “coupled” to the lower object unless the upper object is otherwise maintained substantially in place. That is, for example, a book on a table is not coupled thereto, but a book glued to a table is coupled thereto.
  • the phrase “removably coupled” or “temporarily coupled” means that one component is coupled with another component in an essentially temporary manner. That is, the two components are coupled in such a way that the joining or separation of the components is easy and would not damage the components.
  • two components secured to each other with a limited number of readily accessible fasteners i.e., fasteners that are not difficult to access
  • fasteners that are not difficult to access are “removably coupled”
  • two components that are welded together or joined by difficult to access fasteners are not “removably coupled.”
  • a “difficult to access fastener” is one that requires the removal of one or more other components prior to accessing the fastener wherein the “other component” is not an access device such as, but not limited to, a door.
  • “temporarily disposed” means that a first element(s) or assembly (ies) is resting on a second element(s) or assembly(ies) in a manner that allows the first element/assembly to be moved without having to decouple or otherwise manipulate the first element.
  • a book simply resting on a table i.e., the book is not glued or fastened to the table, is “temporarily disposed” on the table.
  • operatively coupled means that a number of elements or assemblies, each of which is movable between a first position and a second position, or a first configuration and a second configuration, are coupled so that as the first element moves from one position/configuration to the other, the second element moves between positions/configurations as well. It is noted that a first element may be “operatively coupled” to another without the opposite being true.
  • “correspond” indicates that two structural components are sized and shaped to be similar to each other and may be coupled with a minimum amount of friction.
  • an opening which “corresponds” to a member is sized slightly larger than the member so that the member may pass through the opening with a minimum amount of friction.
  • This definition is modified if the two components are to fit “snugly” together. In that situation, the difference between the size of the components is even smaller whereby the amount of friction increases.
  • the element defining the opening and/or the component inserted into the opening are made from a deformable or compressible material, the opening may even be slightly smaller than the component being inserted into the opening.
  • surfaces, shapes, and lines two, or more, “corresponding” surfaces, shapes, or lines have generally the same size, shape, and contours.
  • a “path of travel” or “path,” when used in association with an element that moves, includes the space an element moves through when in motion. As such, any element that moves inherently has a “path of travel” or “path.”
  • a “path of travel” or “path” relates to a motion of one identifiable construct as a whole relative to another object. For example, assuming a perfectly smooth road, a rotating wheel (an identifiable construct) on an automobile generally does not move relative to the body (another object) of the automobile. That is, the wheel, as a whole, does not change its position relative to, for example, the adjacent fender. Thus, a rotating wheel does not have a “path of travel” or “path” relative to the body of the automobile.
  • the air inlet valve on that wheel does have a “path of travel” or “path” relative to the body of the automobile. That is, while the wheel rotates and is in motion, the air inlet valve as a whole, moves relative to the body of the automobile.
  • the statement that two or more parts or components “engage” one another means that the elements exert a force or bias against one another either directly or through one or more intermediate elements or components. Further, as used herein with regard to moving parts, a moving part may “engage” another element during the motion from one position to another and/or may “engage” another element once in the described position. Thus, it is understood that the statements, “when element A moves to element A first position, element A engages element B,” and “when element A is in element A first position, element A engages element B” are equivalent statements and mean that element A either engages element B while moving to element A first position and/or element A either engages element B while in element A first position.
  • operatively engage means “engage and move.” That is, “operatively engage” when used in relation to a first component that is structured to move a movable or rotatable second component means that the first component applies a force sufficient to cause the second component to move.
  • a screwdriver may be placed into contact with a screw. When no force is applied to the screwdriver, the screwdriver is merely “coupled” to the screw. If an axial force is applied to the screwdriver, the screwdriver is pressed against the screw and “engages” the screw. However, when a rotational force is applied to the screwdriver, the screwdriver “operatively engages” the screw and causes the screw to rotate.
  • depending means to extend at an angle other than zero (0°) from another element without regard to direction. That is, for example, a “depending” sidewall may extend generally upwardly from a base. Further, a “depending” sidewall inherently has a distal end.
  • a “tension member” is a construct that has a maximum length when exposed to tension, but is otherwise substantially flexible, such as, but not limited to, a chain or a cable.
  • the word “unitary” means a component that is created as a single piece or unit. That is, a component that includes pieces that are created separately and then coupled together as a unit is not a “unitary” component or body.
  • number shall mean one or an integer greater than one (i.e., a plurality).
  • a “number of elements” means one element or a plurality of elements.
  • [x] moves between its first position and second position,” or, “[y] is structured to move [x] between its first position and second position,” “[x]” is the name of an element or assembly.
  • [x] is an element or assembly that moves between a number of positions
  • the pronoun “its” means “[x],” i.e., the named element or assembly that precedes the pronoun “its.”
  • “about” in a phrase such as “disposed about [an element, point or axis]” or “extend about [an element, point or axis]” or “[X] degrees about an [an element, point or axis],” means encircle, extend around, or measured around.
  • “about” means “approximately,” i.e., in an approximate range relevant to the measurement as would be understood by one of ordinary skill in the art.
  • a “radial side/surface” for a circular or cylindrical body is a side/surface that extends about, or encircles, the center thereof or a height line passing through the center thereof.
  • an “axial side/surface” for a circular or cylindrical body is a side that extends in a plane extending generally perpendicular to a height line passing through the center. That is, generally, for a cylindrical soup can, the “radial side/surface” is the generally circular sidewall and the “axial side(s)/surface(s)” are the top and bottom of the soup can.
  • a “radially extending” means extending in a radial direction. That is, a “radially extending surface” means a surface defined by a plane that extends generally along a radial line and/or a surface that is generally perpendicular to an axial surface.
  • curvilinear includes elements having multiple curved portions, combinations of curved portions and planar portions, and a plurality of planar portions or segments disposed at angles relative to each other thereby forming a curve.
  • sport equipment means equipment used in, or associated with, a sport and which includes an elongated shaft and a head.
  • a “shaft” on sport equipment includes an elongated body that includes, or defines, a handle and/or grip.
  • a “head” on sport equipment means an enlarged portion (such as, but not limited to, the enlarged portion on a golf club or tennis racquet), a blade (such as, but not limited to, on a hockey stick), a striking surface (such as a baseball bat wherein the distal end of the bat is structured to hit a ball and serves a different purpose than the shaft/handle at the proximal end), or a similar construct.
  • the following discussion uses a hockey stick with a blade and a shaft as an example.
  • the training weight assembly is structured to be, and is, coupled to the hockey stick shaft. It is understood that this example is not limiting upon the claims.
  • a “multi-function retention assembly” means a retention assembly that includes at least three retention assemblies or devices.
  • an [X]-function retention assembly means a retention assembly that includes at least [X] retention assemblies or devices, where [X] is an integer above three.
  • a four-function retention assembly includes four or more retention assemblies or devices.
  • a “retention assembly” or “retention device” means an assembly or device structured to maintain a training weight assembly temporarily coupled to sport equipment, or, structured to prevent or resist a training weight assembly from moving to a configuration whereby the training weight assembly can be removed from the sport equipment.
  • a construct that couples a training weight assembly in a permanent or non-temporary manner is not a “retention assembly.”
  • sport equipment 1 and as shown a hockey stick 2 including a shaft 3 and a head 4 (or “blade” 4 ), are structured to be, and is, adapted with a training weight assembly 10 . That is, a training weight assembly 10 is structured to be, and is, temporarily coupled to the sport equipment 1 for training purposes.
  • the training weight assembly 10 includes a mass assembly 20 and a multi-function retention assembly 50 , as shown in FIG. 3 .
  • the mass assembly 20 is structured to be, and is, disposed about the shaft 3 of the sport equipment 1 .

That is, the training weight assembly 10 is structured so as to not be disposed on or over the head 4 of the sport equipment 1 . This solves the problem(s) stated above as the training weight assembly 10 does not interfere with the head 4 of the sport equipment 1 as it engages a ball, puck, or similar construct associated with the sport equipment 1 .

Description

    BACKGROUND OF THE INVENTION Field of the Invention
  • The disclosed and claimed concept relates to training weights that are structured to be, and are, coupled to sports equipment.
  • Background Information
  • Training weights used with sports equipment are known in a number of different sports. A toroid, i.e., ring-shaped, weight used with baseball bats are a familiar example. As is known, baseball bats have a grip with a relatively small diameter, a taper that increases the diameter, and a barrel that has a greater diameter relative to the grip. A training weight for a baseball bat has an inner diameter that is larger than the grip but smaller than the barrel. Thus, the training weight is coupled to the bat by passing the grip through the training weight and moving the training weight toward the barrel until the training weight is snuggly coupled to the baseball bat. Moreover, given the swinging motion associated with a baseball bat, the training weight is unlikely to accidentally decouple from the baseball bat. That is, the momentum of the training weight when the baseball bat is in motion biases the training weight toward the end of barrel. As the barrel is wider than the opening in the training weight, the training weight cannot slip off the baseball bat.
  • Not all sports equipment is tapered like a baseball bat nor utilized like a baseball bat. For example, hockey sticks have a wide, arcuate blade, grip/butt end and shaft therebetween. The grip/butt end, in an exemplary embodiment, has a greater cross-sectional area relative to the shaft. In this configuration, a training weight similar to a training weight for a baseball bat is not useful. That is, to pass the grip/butt end, the opening in such a training weight would have a greater cross-sectional area. As the grip/butt end has a greater cross-sectional area than the shaft, the opening in such a training weight would also be larger than the shaft cross-sectional area. In this configuration, the training weight would not be snug on the shaft. That is, the training weight could shift up and down the shaft and would likely damage the hockey stick.
  • To overcome these disadvantages, several training weight devices for hockey sticks have been developed. Each of these designs, however, have disadvantages. For example, U.S. Pat. No. 5,520,386 discloses a training weight with an inverted U-shaped body that snuggly fits over the blade as well as a tether. The disadvantage to this configuration is that the training weight covers the blade so that the hockey stick does not properly connect with a puck. Further, given the motion of a hockey stick in use, only the tether is a secure retaining device. That is, the training weight body is able to disengage from the blade and, if the tether fails, the training weight could be thrown through the air. This would be unsafe and is a problem.
  • The training weight devices disclosed in U.S. Pat. Nos. D438,585 and 6,328,666 are spaced from the blade (and therefore do not interfere with the puck), when clamped about the shaft. These devices, however, are secured by threaded fasteners. Such fasteners are time consuming to utilize. Further, the training weight devices may damage the shaft of the hockey stick. Finally, these devices have only the threaded fasteners to retain the training weight device on the hockey stick. That is, there is no additional safety assembly. These are problems.
  • Other training weight devices, such as those disclosed in U.S. Pat. No. 4,364,560 and U.S. Patent Publication No. 2004/0132589, include weighted elements that are coupled to a hockey stick by hook-and-loop material. Hook-and-loop material, however, may detach when exposed to impacts and other motions typically experienced by a hockey stick. This is a problem as the training weight device of U.S. Patent Publication No. 2004/0132589 does not have any other retention devices. The training weight device disclosed in U.S. Pat. No. 4,364,560 includes threaded fasteners that engage the shaft as an additional retention device. The fasteners, however, may damage the shaft. These are problems. Still other training weight devices include weights that are disposed within the shaft of the hockey stick. These devices are semi-permanent in that removal of the weights requires disassembly of the sport equipment. That is, they cannot be removed easily. This is also a problem.
  • Further, many training weight devices include straps, fasteners and other elements that protrude from the bulk of the training weight device. Such protrusions increase the likelihood of the training weight device interfering with the associated sport. That is, for example, a strap could drag along the ice and interfere with a player's skates. Further, many of the training weight devices noted above are made from a hard material, such as, but not limited to, steel. Such hard materials are likely to scratch or otherwise damage the sport equipment. For example, a training weight device having a generally circular passage which is disposed on a generally cylindrical shaft is likely to rotate about the shaft. When this happens, hard materials defining the passage are likely to scratch or otherwise damage the shaft. These are further problems with the known training weight devices.
  • There is, therefore, a need for a training weight assembly that does not have the problems associated with the prior art training weight devices. There is a further need for a training weight assembly that includes more than two retention devices or assemblies. That is, a training weight device that becomes free during use is dangerous and may injure other people near the user. Known training weight devices are limited to one or two retention devices. This may still be unsafe as, due to the nature of how hockey sticks, or other sport equipment, are used, the retention devices may become unbound or otherwise damaged.
  • SUMMARY OF THE INVENTION
  • These needs, and others, are met by at least one embodiment of the disclosed and claimed concept which provides a training weight assembly that is structured to be coupled to sport equipment having a shaft and a head. The training weight assembly includes a mass assembly and a multi-function retention assembly. The mass assembly is structured to be disposed about the shaft.

  • DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • It will be appreciated that the specific elements illustrated in the figures herein and described in the following specification are simply exemplary embodiments of the disclosed concept, which are provided as non-limiting examples solely for the purpose of illustration. Therefore, specific dimensions, orientations, assembly, number of components used, embodiment configurations and other physical characteristics related to the embodiments disclosed herein are not to be considered limiting on the scope of the disclosed concept.
  • Directional phrases used herein, such as, for example, clockwise, counterclockwise, left, right, top, bottom, upwards, downwards and derivatives thereof, relate to the orientation of the elements shown in the drawings and are not limiting upon the claims unless expressly recited therein.
  • As used herein, the singular form of “a,” “an,” and “the” include plural references unless the context clearly dictates otherwise.
  • As used herein, “structured to [verb]” means that the identified element or assembly has a structure that is shaped, sized, disposed, coupled and/or configured to perform the identified verb. For example, a member that is “structured to move” is movably coupled to another element and includes elements that cause the member to move or the member is otherwise configured to move in response to other elements or assemblies. As such, and as used herein, “structured to [verb]” recites structure and not function. Further, as used herein, “structured to [verb]” means that the identified element or assembly is intended to, and is designed to, perform the identified verb. Thus, an element that is merely capable of performing the identified verb but which is not intended to, and is not designed to, perform the identified verb is not “structured to [verb].”
  • As used herein, “associated” means that the elements are part of the same assembly and/or operate together, or, act upon/with each other in some manner. For example, an automobile has four tires and four hub caps. While all the elements are coupled as part of the automobile, it is understood that each hubcap is “associated” with a specific tire.
  • As used herein, a “coupling assembly” includes two or more couplings or coupling components. The components of a coupling or coupling assembly are generally not part of the same element or other component. As such, the components of a “coupling assembly” may not be described at the same time in the following description.
  • As used herein, a “coupling” or “coupling component(s)” is one or more component(s) of a coupling assembly. That is, a coupling assembly includes at least two components that are structured to be coupled together. It is understood that the components of a coupling assembly are compatible with each other. For example, in a coupling assembly, if one coupling component is a snap socket, the other coupling component is a snap plug, or, if one coupling component is a bolt, then the other coupling component is a nut.
  • As used herein, a “fastener” is a separate component structured to couple two or more elements. Thus, for example, a bolt is a “fastener” but a tongue-and-groove coupling is not a “fastener.” That is, the tongue-and-groove elements are part of the elements being coupled and are not a separate component.
  • As used herein, the statement that two or more parts or components are “coupled” shall mean that the parts are joined or operate together either directly or indirectly, i.e., through one or more intermediate parts or components, so long as a link occurs. As used herein, “directly coupled” means that two elements are directly in contact with each other. As used herein, “fixedly coupled” or “fixed” means that two components are coupled so as to move as one while maintaining a constant orientation relative to each other. Accordingly, when two elements are coupled, all portions of those elements are coupled. A description, however, of a specific portion of a first element being coupled to a second element, e.g., an axle first end being coupled to a first wheel, means that the specific portion of the first element is disposed closer to the second element than the other portions thereof. Further, an object resting on another object held in place only by gravity is not “coupled” to the lower object unless the upper object is otherwise maintained substantially in place. That is, for example, a book on a table is not coupled thereto, but a book glued to a table is coupled thereto.
  • As used herein, the phrase “removably coupled” or “temporarily coupled” means that one component is coupled with another component in an essentially temporary manner. That is, the two components are coupled in such a way that the joining or separation of the components is easy and would not damage the components. For example, two components secured to each other with a limited number of readily accessible fasteners, i.e., fasteners that are not difficult to access, are “removably coupled” whereas two components that are welded together or joined by difficult to access fasteners are not “removably coupled.” A “difficult to access fastener” is one that requires the removal of one or more other components prior to accessing the fastener wherein the “other component” is not an access device such as, but not limited to, a door.
  • As used herein, “temporarily disposed” means that a first element(s) or assembly (ies) is resting on a second element(s) or assembly(ies) in a manner that allows the first element/assembly to be moved without having to decouple or otherwise manipulate the first element. For example, a book simply resting on a table, i.e., the book is not glued or fastened to the table, is “temporarily disposed” on the table.
  • As used herein, “operatively coupled” means that a number of elements or assemblies, each of which is movable between a first position and a second position, or a first configuration and a second configuration, are coupled so that as the first element moves from one position/configuration to the other, the second element moves between positions/configurations as well. It is noted that a first element may be “operatively coupled” to another without the opposite being true.
  • As used herein, “correspond” indicates that two structural components are sized and shaped to be similar to each other and may be coupled with a minimum amount of friction. Thus, an opening which “corresponds” to a member is sized slightly larger than the member so that the member may pass through the opening with a minimum amount of friction. This definition is modified if the two components are to fit “snugly” together. In that situation, the difference between the size of the components is even smaller whereby the amount of friction increases. If the element defining the opening and/or the component inserted into the opening are made from a deformable or compressible material, the opening may even be slightly smaller than the component being inserted into the opening. With regard to surfaces, shapes, and lines, two, or more, “corresponding” surfaces, shapes, or lines have generally the same size, shape, and contours.
  • As used herein, a “path of travel” or “path,” when used in association with an element that moves, includes the space an element moves through when in motion. As such, any element that moves inherently has a “path of travel” or “path.” Further, a “path of travel” or “path” relates to a motion of one identifiable construct as a whole relative to another object. For example, assuming a perfectly smooth road, a rotating wheel (an identifiable construct) on an automobile generally does not move relative to the body (another object) of the automobile. That is, the wheel, as a whole, does not change its position relative to, for example, the adjacent fender. Thus, a rotating wheel does not have a “path of travel” or “path” relative to the body of the automobile. Conversely, the air inlet valve on that wheel (an identifiable construct) does have a “path of travel” or “path” relative to the body of the automobile. That is, while the wheel rotates and is in motion, the air inlet valve as a whole, moves relative to the body of the automobile.
  • As used herein, the statement that two or more parts or components “engage” one another means that the elements exert a force or bias against one another either directly or through one or more intermediate elements or components. Further, as used herein with regard to moving parts, a moving part may “engage” another element during the motion from one position to another and/or may “engage” another element once in the described position. Thus, it is understood that the statements, “when element A moves to element A first position, element A engages element B,” and “when element A is in element A first position, element A engages element B” are equivalent statements and mean that element A either engages element B while moving to element A first position and/or element A either engages element B while in element A first position.
  • As used herein, “operatively engage” means “engage and move.” That is, “operatively engage” when used in relation to a first component that is structured to move a movable or rotatable second component means that the first component applies a force sufficient to cause the second component to move. For example, a screwdriver may be placed into contact with a screw. When no force is applied to the screwdriver, the screwdriver is merely “coupled” to the screw. If an axial force is applied to the screwdriver, the screwdriver is pressed against the screw and “engages” the screw. However, when a rotational force is applied to the screwdriver, the screwdriver “operatively engages” the screw and causes the screw to rotate.
  • As used herein, “depending” means to extend at an angle other than zero (0°) from another element without regard to direction. That is, for example, a “depending” sidewall may extend generally upwardly from a base. Further, a “depending” sidewall inherently has a distal end.
  • As used herein, a “tension member” is a construct that has a maximum length when exposed to tension, but is otherwise substantially flexible, such as, but not limited to, a chain or a cable. As used herein, the word “unitary” means a component that is created as a single piece or unit. That is, a component that includes pieces that are created separately and then coupled together as a unit is not a “unitary” component or body.
  • As used herein, the term “number” shall mean one or an integer greater than one (i.e., a plurality). Thus, for example, a “number of elements” means one element or a plurality of elements.
  • As used herein, in the phrase “[x] moves between its first position and second position,” or, “[y] is structured to move [x] between its first position and second position,” “[x]” is the name of an element or assembly. Further, when [x] is an element or assembly that moves between a number of positions, the pronoun “its” means “[x],” i.e., the named element or assembly that precedes the pronoun “its.”
  • As used herein, “about” in a phrase such as “disposed about [an element, point or axis]” or “extend about [an element, point or axis]” or “[X] degrees about an [an element, point or axis],” means encircle, extend around, or measured around. When used in reference to a measurement or in a similar manner, “about” means “approximately,” i.e., in an approximate range relevant to the measurement as would be understood by one of ordinary skill in the art.
  • As used herein, a “radial side/surface” for a circular or cylindrical body is a side/surface that extends about, or encircles, the center thereof or a height line passing through the center thereof. As used herein, an “axial side/surface” for a circular or cylindrical body is a side that extends in a plane extending generally perpendicular to a height line passing through the center. That is, generally, for a cylindrical soup can, the “radial side/surface” is the generally circular sidewall and the “axial side(s)/surface(s)” are the top and bottom of the soup can. Further, as used herein, a “radially extending” means extending in a radial direction. That is, a “radially extending surface” means a surface defined by a plane that extends generally along a radial line and/or a surface that is generally perpendicular to an axial surface.
  • As used herein, “generally curvilinear” includes elements having multiple curved portions, combinations of curved portions and planar portions, and a plurality of planar portions or segments disposed at angles relative to each other thereby forming a curve.
  • As used herein, “generally” means “in a general manner” relevant to the term being modified as would be understood by one of ordinary skill in the art.
  • As used herein, “substantially” means “for the most part” relevant to the term being modified as would be understood by one of ordinary skill in the art.
  • As used herein, “at” means on and/or near relevant to the term being modified as would be understood by one of ordinary skill in the art.
  • As used herein, “sport equipment” means equipment used in, or associated with, a sport and which includes an elongated shaft and a head. As used herein, a “shaft” on sport equipment includes an elongated body that includes, or defines, a handle and/or grip. As used herein, a “head” on sport equipment means an enlarged portion (such as, but not limited to, the enlarged portion on a golf club or tennis racquet), a blade (such as, but not limited to, on a hockey stick), a striking surface (such as a baseball bat wherein the distal end of the bat is structured to hit a ball and serves a different purpose than the shaft/handle at the proximal end), or a similar construct. The following discussion uses a hockey stick with a blade and a shaft as an example. The training weight assembly is structured to be, and is, coupled to the hockey stick shaft. It is understood that this example is not limiting upon the claims.
  • As used herein, a “multi-function retention assembly” means a retention assembly that includes at least three retention assemblies or devices. Further, as used herein, an [X]-function retention assembly means a retention assembly that includes at least [X] retention assemblies or devices, where [X] is an integer above three. Thus, a four-function retention assembly includes four or more retention assemblies or devices.
  • As used herein, a “retention assembly” or “retention device” means an assembly or device structured to maintain a training weight assembly temporarily coupled to sport equipment, or, structured to prevent or resist a training weight assembly from moving to a configuration whereby the training weight assembly can be removed from the sport equipment. Thus, a construct that couples a training weight assembly in a permanent or non-temporary manner is not a “retention assembly.”
  • As shown in FIG. 1, sport equipment 1, and as shown a hockey stick 2 including a shaft 3 and a head 4 (or “blade” 4), are structured to be, and is, adapted with a training weight assembly 10. That is, a training weight assembly 10 is structured to be, and is, temporarily coupled to the sport equipment 1 for training purposes. In an exemplary embodiment, shown in FIGS. 2-4, the training weight assembly 10 includes a mass assembly 20 and a multi-function retention assembly 50, as shown in FIG. 3. The mass assembly 20 is structured to be, and is, disposed about the shaft 3 of the sport equipment 1. The multi-function retention assembly 50 is structured to, and does, temporarily couple the mass assembly 20 to the shaft 3 of the sport equipment 1. In an exemplary embodiment, the mass assembly 20 and the multi-function retention assembly 50 are, i.e., the training weight assembly 10 is, structured to be, and is, coupled to said sport equipment at a location spaced from head 4 of the sport equipment 1. That is, the training weight assembly 10 is structured so as to not be disposed on or over the head 4 of the sport equipment 1. This solves the problem(s) stated above as the training weight assembly 10 does not interfere with the head 4 of the sport equipment 1 as it engages a ball, puck, or similar construct associated with the sport equipment 1.
  • In an exemplary embodiment, the mass assembly 20 includes a first body 22 and a second body 24. As discussed below, the mass assembly first body 22 and mass assembly second body 24 are, in an exemplary embodiment, made from a moldable material such as, but not limited to, an elastomer/plastic. Further, the molded mass assembly first body 22 and mass assembly second body 24, in an exemplary embodiment, each include an upper portion 22A, 24A and a lower portion 22B, 24B which are structured to be, and are, coupled to each other by a number of coupling assemblies 29. Generally, hereinafter, the mass assembly first body 22 and mass assembly second body 24 will be identified without reference to the upper portions 22A, 24A and the lower portions 22B, 24B. In another exemplary embodiment, the mass assembly first body 22 and mass assembly second body 24 are each unitary bodies.
  • The first body 22 and second body 24 may be any shape but are, in the embodiment shown, generally semi-cylindrical. Thus, when coupled and in a second configuration, as discussed below, the mass assembly 20 is generally cylindrical or disk shaped. In an exemplary embodiment, the generally cylindrical mass assembly 20 is generally the same size as a standard hockey puck.
  • In an exemplary embodiment, the first body 22 is a generally semi-cylindrical body 26 including a first end 28, a second end 30, and a radially extending surface 32. The first body radially extending surface 32 defines a shaft passage first portion 34. In an exemplary embodiment, the shaft passage first portion 34 is a channel in the first body radially extending surface 32. For a training weight assembly 10 structured to be coupled to a hockey stick 2, the shaft passage first portion 34 has a generally rectangular cross-section when viewed axially, as shown in FIG. 2. In this configuration, the first body first end 28 is disposed on one side of the shaft passage first portion 34 and the first body second end 30 is disposed on the other side of the shaft passage first portion 34. Further, the named elements of the first body 22 can be combined to more specifically identify a portion of the first body 22. For example, the “first body second end radially extending surface” 31 means the first body radially extending surface 32 at the first body second end 30.
  • In an exemplary embodiment, the second body 24 is a generally semi-cylindrical body 40 including a first end 42, a second end 44, and a radially extending surface 46. The second body radially extending surface 46 defines a shaft passage second portion 48. In an exemplary embodiment, the shaft passage second portion 48 is a channel in the second body radially extending surface 46. For a training weight assembly 10 structured to be coupled to a hockey stick 2, the shaft passage second portion 48 has a generally rectangular cross-section when viewed axially, as shown in FIG. 2. In this configuration, the second body first end 42 is disposed on one side of the shaft passage second portion 48 and the second body second end 44 is disposed on the other side of the shaft passage second portion 48. As before, the named elements of the second body 24 can be combined to more specifically identify a portion of the second body 24. For example, the “second body second end radially extending surface” 43 means the second body radially extending surface 46 at the second body second end 44.
  • The first body 22 and the second body 24 are rotatably coupled to each other with an axis of rotation 14 disposed at the first body first end 28 and at the second body first end 42. In an exemplary embodiment, the first body 22 and the second body 24 are rotatably coupled at a hinge 16 (shown schematically) that includes a number of generally circular passages (not numbered) that, when the first body 22 and the second body 24 are coupled, are aligned, as well as a pin (not shown) extending through the passages. Thus, the mass assembly 20 moves between, or the first body 22 and the second body 24 are configurable in, a first configuration, wherein the first body 22 and the second body 24 are not disposed immediately adjacent each other, and a second configuration, wherein the first body 22 and the second body 24 are disposed immediately adjacent each other and wherein the shaft passage first portion 34 and the shaft passage second portion 48 define a shaft passage 18 (FIG. 2). That is, as the first body 22 and the second body 24 are rotatably coupled at their respective first ends 28, 42, when the first body 22 and the second body 24 are in the first configuration, the planes defining the first body radially extending surface 32 and the second body radially extending surface 46 are at an angle. As used herein, when the first body 22 and the second body 24 are in this configuration they are not “immediately adjacent each other” even though their respective first ends 28, 42 are coupled.
  • Further, in the first configuration, the first body second end 30 and the second body second end 44 are spaced a distance greater that the cross-sectional width of the shaft 3. That is, it is understood that a training weight assembly 10 is structured to be temporarily coupled to a specific type, model, size of sport equipment 1 with a specific shaft 3. When the first body 22 and the second body 24 are in the first configuration, the first body second end 30 and the second body second end 44, and/or the shaft passage first portion 34 and the shaft passage second portion 48, are spaced a distance sufficient to allow the associated shaft 3 to pass therebetween. In an exemplary embodiment, the first body 22 and the second body 24 are disposed in the first configuration by rotating the first body 22 away from the second body 24 at the hinge 16.
  • In the second configuration, the first body radially extending surface 32 and the second body radially extending surface 46 are disposed immediately adjacent, or in contact with, each other. Further, the shaft passage 18 is formed when the first body 22 and the second body 24 are in the second configuration. The shaft passage 18 corresponds, or snuggly corresponds, to the cross-sectional area and shape of the associated shaft 3. In an exemplary embodiment, the shaft passage 18 includes an interior surface 17 and has a generally rectangular cross-sectional shape. Further, the shaft passage interior surface 17 is defined by a pliable material 19. As used herein, a “pliable material” means a deformable material and does not mean a material that increases the co-efficient of friction. In one embodiment, the “pliable material” is a silicone (or silicone like) material covering a foam material. That is, a weight training device, such as the one disclosed in U.S. Pat. No. 6,083,116 for a cylindrical golf club shaft, includes a material that increases the co-efficient of friction so as to prevent the rotation of the weight training device about the golf club shaft. Such a material is disclosed as rubber or a silicone elastomeric material. While these materials are resilient, they are used as a material that increases the co-efficient of friction. Thus, these materials, when used to increase the co-efficient of friction are not, as used herein, a “pliable material.” Further, as used herein, a passage that is shaped to prevent rotation of the training weight assembly 10 and which includes a pliable material is a “protecting passage.” A passage that has a cross-sectional shape that is other than generally circular is shaped to prevent rotation. Thus, the rectangular shaft passage 18 with a pliable material 19 is a “protecting passage.” A protecting passage solves the problem(s) stated above.
  • The first body 22 and the second body 24, as shown in FIG. 3, in an exemplary embodiment, each include a molded portion 21 and a weighted portion 23 (the portions are collectively identified, see FIG. 2). That is, as used herein, the “molded portion” is the portion of the training weight assembly 10 on both sides of the hinge 16. Similarly, as used herein, the weighted portion 23 includes any added material that has a greater density than the molded portion 21 regardless of which side of hinge 16 the material is on. Conversely, the first body 22 and the second body 24 are on different sides of the hinge 16 and include both the molded material and the added material that has a greater density than the molded portion 21. Each molded portion 21 is made from a moldable material such as, but not limited to rubber, plastic, or a poly material. Each weighted portion 23 is made from a material that has a greater density than the molded portion 21 such as, but not limited to, a metal and which is an added material. As used herein, an “added material” is a material included in the first body 22 and the second body 24 that has a primary function of adding mass/weight. Thus, while a coupling component, such as, but not limited to a metal screw has a density than the molded portion 21, the screw has a primary purpose of coupling other elements to each other. In an exemplary embodiment, not shown, the molded portion 21 defines a number of pockets. Each weighted portion 23 is sized and shaped to correspond to the pocket(s). In this configuration, different weighted portions 23 are structured to be swapped, thereby changing the weight of the training weight assembly 10. That is, for example, one weighted portion 23 includes elements that collectively weigh about one pound or, in another embodiment, between 0.5 pound and 1.00 pound, or about 0.75 pound. Another weighted portion 23 includes elements that collectively weigh about two pounds. The weighted portion 23 elements are, in one embodiment, structured to be swapped. Alternatively, a user couples/decouples multiple training weight assemblies 10 to the sport equipment 1 to increase/decrease the total weight of the training weight assemblies 10. Further, in an exemplary embodiment, the first body 22 and the second body 24 each define a channel 13, 15 (FIG. 4) that extends about, or just inside, the radial surfaces of the first body 22 and the second body 24, as discussed below.
  • The training weight assembly 10 includes a multi-function retention assembly 50. As defined above, a “multi-function retention assembly” means a retention assembly that includes at least three retention assemblies or devices. In an exemplary embodiment, the multi-function retention assembly 50 includes a number of automatic retention assemblies 60 and a number of manual retention assemblies 150.
  • The multi-function retention assembly 50, FIG. 3, is structured to, and does, maintain the training weight assembly 10 temporarily coupled to the sport equipment 1 while allowing the training weight assembly 10 to be removed when no longer needed. Thus, the multi-function retention assembly 50 is configurable in a first configuration, wherein the first body 22 and the second body 24 are free to move between configurations, and, a second configuration, wherein the first body 22 and the second body 24 are maintained in the second configuration. As used herein, to “maintain [the first body 22 and the second body 24] in the second configuration” means that the bodies 22, 24 can only be moved from the second configuration by a force that damages the bodies 22, 24 or by actuating the multi-function retention assembly 50. Further, in an exemplary embodiment, when the multi-function retention assembly 50 is in the second configuration, said multi-function retention assembly 50 “resists” allowing the first body 22 and the second body 24 moving from the second configuration to the first configuration. As used herein, “resists” in the term “resists the first body 22 and the second body 24 moving from the second configuration to the first configuration” means that more than the force of gravity is needed to move the first body 22 and the second body 24 to the first configuration. That is, for example, the lid on a box with a hinged lid, when flipped upside down, will fall due to gravity and allow access to the interior of the box. Conversely, if the same box and lid have magnets disposed therein with a magnetic attraction that is greater than the weight of the lid, when the box is flipped upside down, the lid will not fall. Thus, the magnetic force “resists” the movement of the lid. It is understood that the addition of a slight force will overcome the force that “resists” the motion of the first body 22 and the second body 24 from the second configuration to the first configuration. As used herein, a “slight force” means a force which is about, or more than about, 150% of the weight of the movable element which is restrained by the multi-function retention assembly 50.
  • As noted above, the multi-function retention assembly 50 includes a number of automatic retention assemblies 60 and a number of manual retention assemblies 150. As used herein, an “automatic retention assembly” means a retention assembly that engages the retention capability when the first body 22 and the second body 24 move from the first configuration to the second configuration, and/or which are always configured/positioned to resist separation of the training weight assembly 10 and the sport equipment 1. It is noted that a construct or assembly that resists the separation of the first body 22 and the second body 24 also resists separation of the training weight assembly 10 and the sport equipment 1. Automatic retention assemblies 60 are selected from the group including, consisting of, or consisting essentially of, spring retention assemblies 70 (FIG. 3), magnetic retention assemblies 80 (FIG. 4), labyrinthine retention assemblies 90 (FIG. 6), close-to-engage retention assemblies 100 (FIG. 3), trapping retention assemblies 120 (FIG. 3), narrowing retention assembly 130 (FIG. 9) and protected retention assemblies 140 (FIG. 3).
  • In an exemplary embodiment, a spring retention assembly 70 includes a spring mounting (not shown) on each of the first body 22 and the second body 24 as well as a spring 76, shown schematically, that is structured to be, and is, coupled, directly coupled, or fixed to each spring mounting. In one embodiment, the spring mountings are the first body 22 and the second body 24 that define the hinge 16. In this embodiment, the spring 76 is a torsion spring that biases the first body 22 and the second body 24 to the second configuration. This configuration is, as used herein, a “hinge spring assembly” 79. In an exemplary embodiment, the hinge spring assembly 79 is dispose at the axis of rotation 14.
  • In another embodiment, shown in FIG. 5, the first body 22 and the second body 24 are not pivotally connected. Instead, the multi-function retention assembly 50 includes interlocking tongue-and-groove 62 couplings. The tongue-and-groove 62 couplings are disposed at the ends 28, 30 and 42, 44 of the first body 22 and the second body 24. Further, multi-function retention assembly 50 includes the radial surface channels 13, 15, discussed above, which are the spring mountings and the spring 76 is an arcuate leaf spring 78 that extends over an arc that is greater than 180°, or, in another embodiment, over an arc greater than 270°. In this embodiment, the gap between the ends of the arcuate leaf spring 78 is disposed at the interface of the first body second end 30 and the second body second end 44. In an exemplary embodiment, the spring retention assembly 70 resists the motion of the first body 22 and said second body 24 from the second configuration to the first configuration. That is, a user is able to apply a manual force to the first body 22 and said second body 24 to overcome the force of the spring retention assembly 70.
  • In an exemplary embodiment, shown in FIG. 4, a magnetic retention assembly 80 includes a plurality of magnets 82, 84 (two shown). The magnets are disposed in opposition at the first body radially extending surface 32 and at said second body radially extending surface 46. As used herein, “disposed in opposition” means that each of a first set of elements and a second set of elements are disposed on different bodies/constructs wherein the bodies/constructs are separable, and, wherein when the bodies/constructs are adjacent each other, the first set of elements and the second set of elements are adjacent each other. For example, page numbers in books are typically disposed “in opposition” to each other in that the pages are separable wherein the page numbers are not immediately adjacent each other, but when the book is closed, the pages numbers are immediately adjacent each other. Further to be “disposed in opposition,” when the second set of elements are brought together, each element of the first set of elements is disposed immediately adjacent, or in contact with, one of the other elements of the first set of elements. In an exemplary embodiment, the magnets 82, 84 are disposed at the first body second end 30 and the second body second end 44, respectively. It is understood that the poles of the magnets 82, 84 are oriented so that the magnets are attracted to each other.
  • As used herein, and as shown in FIG. 6, a “labyrinthine retention assembly” 90 includes elements that increase the separation needed between the first body 22 and the second body 24 so that the shaft 3 can pass therebetween. In an exemplary embodiment, a labyrinthine retention assembly 90 includes an extension 92 from the first body second end radially extending surface 31 and a pocket 94 in the second body second end radially extending surface 43. The labyrinthine retention assembly extension 92 is sized and shaped to correspond to the labyrinthine retention assembly pocket 94. Further, in an exemplary embodiment, the labyrinthine retention assembly extension 92 is an “extended” extension 92. As used herein, an “extended” extension 92 is an extension that has a length of over one inch, and/or, in an extension having an arcuate surface, an extension that extends over an arc of 80°. An “extended” pocket 94 corresponds to an “extended” extension 92. Further, the labyrinthine retention assembly extension 92 is, in an exemplary embodiment, “contoured.” As used herein, a “contoured” labyrinthine retention assembly extension 92 has an outer surface that generally corresponds to the shape of the opposing body, second body 24 as shown, when the first body 22 and the second body 24 are in the second configuration. That is, as shown, the labyrinthine retention assembly pocket 94 effectively removes a portion of the second body 24; when the first body 22 and the second body 24 are in the second configuration, the “contoured” labyrinthine retention assembly extension 92 fills the cavity created by the labyrinthine retention assembly pocket 94 and the outer surface of the “contoured” labyrinthine retention assembly extension 92 corresponds to the outer surface of the second body 24.
  • A close-to-engage retention assembly 100, as shown in FIG. 3, is an assembly that includes a first component 102 and a second component 104 that are structured to be, and are, coupled and to “resist” separation. For example, patches of hook-and-loop material (not shown) on a second body second end radially extending surface 31 and the second body second end radially extending surface 43 define a close-to-engage retention assembly 100. Further, a close-to-engage retention assembly 100 includes a coupling such as, but not limited to, an expanding coupling, not shown, that includes a body enclosing movable parts with cams structured to move the movable parts outwardly. An actuator is used to release the cams and allow the movable parts to move inwardly. In this configuration, the expanding coupling is released and can be moved out of a passage with a corresponding size. When the actuator is released, a spring, or similar biasing device, moves the movable parts outwardly. The movable parts engage the passage. This is the locked position of the expanding coupling.
  • In the embodiment shown, the close-to-engage retention assembly 100 includes a plug-and-socket retention assembly 110. The plug-and-socket retention assembly 110 includes a plug 112 that extends from the first body second end radially extending surface 43 and a socket 114 in the second body second end radially extending surface 31. The socket 114 is generally resilient and defines a cavity 116 that snuggly corresponds to the plug 112. When the first body 22 and the second body 24 are in the second configuration, the plug 112 is disposed in the socket cavity 116. The resilient characteristics of the socket 114 resists separation of the plug 112 from the cavity 116 when the first body 22 and the second body 24 are moved from the second configuration to the first configuration.
  • As used herein, a “trapping” retention assembly 120 is structured to, and does, fill the gap between the first body second end 30 and the second body second end 44 when the first body 22 and the second body 24 are in the first configuration. That is, the trapping retention assembly 120 is disposed adjacent the first body second end 30 and the second body second end 44, i.e., spaced from the hinge 16. In this configuration, the trapping retention assembly 120 is structured to, and does, prevent the sport equipment 1, i.e., the shaft 3, from passing through the gap between the molded mass assembly first body 22 and mass assembly second body 24. In an exemplary embodiment, the trapping retention assembly 120 includes a tension member, as shown limiter strap 122, having a body 124 with a first end 126, a medial portion 125 and a second end 128. The limiter strap body 124 is disposed in a hidden pocket channel 142, discussed below. The limiter strap body second end 128 is, in an exemplary embodiment, coupled, directly coupled, or fixed to the second body 24. The limiter strap body first end 126 includes a stopper 129 that is structured to, and does, resist separation of the limiter strap body 124 from the hidden pocket channel 142/the first body 22. That is, the hidden pocket channel 142 includes a passage in the first body 22 and, as shown in the first body second end radially extending surface 31. The stopper 129 has a greater cross-sectional area than the opening of the passage. In this configuration, the stopper 129, and therefore the limiter strap body 124, cannot pass through the opening of the passage. In this configuration, the trapping retention assembly 120 operates as follows; when the first body 22 and the second body 24 are in the second configuration, the limiter strap body 124 is substantially disposed in the hidden pocket channel 142. When the first body 22 and the second body 24 move to the second configuration, the limiter strap body second end 128 moves with the second body 24 while the limiter strap body first end 126 moves relative to the first body 22. This action causes the limiter strap body medial portion 125, i.e., essentially all of the limiter strap body 124 except the two ends 126, 128, to move out of the hidden pocket channel 142. In this configuration, the limiter strap body 124 extends across, i.e., fills, the gap between the first body second end 30 and the second body second end 44 when the first body 22 and the second body 24 are in the first configuration. Further, in this configuration, the sport equipment shaft 3 cannot pass through the gap between the first body second end 30 and the second body second end 44 when the first body 22 and the second body 24 are in the first configuration. Thus, the trapping retention assembly 120 is structured to, and does, maintain the training weight assembly 10 temporarily coupled to the sport equipment 1.
  • Similar to the trapping retention assembly 120, a “narrowing” retention assembly 130 includes a narrowing strap 132, as shown in FIGS. 9 and 10. The trapping retention assembly limiter strap 122 and the narrowing retention assembly narrowing strap 132 define, i.e., set the limit/boundary of, a passage that has a smaller dimension than one dimension of the sport equipment head 4. As used herein, a narrowing retention assembly 130 is structured to, and does, reduce at least one dimension that defines the cross-sectional area between the first body 22 and the second body 24 when the first body 22 and the second body 24 are in the first configuration. That is, in many sports, the sport equipment shaft 3 and head 4 have different cross-sectional shapes. For example, a hockey stick 2 has a generally planar head 4 and a generally oval or rectangular shaft 3. Depending upon the specific dimensions, a hockey stick shaft may have a larger, or smaller, cross-sectional area relative to the hockey stick head 4. At least one dimension, however, on the hockey stick head 4 is much larger than both dimensions defining the hockey stick shaft 3. That is, generally, the hockey stick head 4 has a relatively small (relative to the other head 4 dimensions) thickness, and, a relatively large length and height. Despite this relatively large height, the gap between the hinge 16 and the first body second end 30/the second body second end 44 is, in an exemplary embodiment, larger. Thus, even with a trapping retention assembly 120 in place, the training weight assembly 10 (when in the first body 22 and the second body 24 are in the first configuration), the radially extending length of the gap between the first body 22 and the second body 24 in the first configuration. In an exemplary embodiment, the “narrowing” retention assembly 130 is structured to, and does, reduce the radially extending length of the gap between the first body 22 and the second body 24 in the first configuration.
  • The narrowing retention assembly 130 includes a narrowing strap 132 having a body 134 with a first end 136, a medial portion 135 and a second end 138. As used herein, a “narrowing strap” means a strap that is structured to, and does, narrow at least one dimension that defines the cross-sectional area between the first body 22 and the second body 24 when the first body 22 and the second body 24 are in the first configuration. That is, a “narrowing strap” does not mean a strap or body that is wide at one end and narrow at the other. The narrowing retention assembly 130 is disposed adjacent the first body first end 28 and at the second body first end 42, i.e., adjacent the hinge 16. The narrowing strap body 134 is disposed in a hidden pocket channel 142, discussed below. The narrowing strap body second end 138 is, in an exemplary embodiment, coupled, directly coupled, or fixed to the second body 24. The narrowing strap body first end 136 includes a stopper 139 that is structured to, and does, resist separation of the narrowing strap body 134 from the hidden pocket channel 142/the first body 22. When the first body 22 and the second body 24 are in the first configuration, the maximum distance between the trapping retention assembly limiter strap 122 and the narrowing retention assembly narrowing strap 132 is less than the height, i.e., one dimension of, the hockey stick head 4. In this configuration, the training weight assembly 10 cannot move longitudinally over, and then off, the hockey stick head 4. It is noted that, just as a hypotenuse is longer than the sides of a rectangle, the maximum distance between the trapping retention assembly limiter strap 122 and the narrowing retention assembly narrowing strap 132 is not measured along a radially extending line, but rather at an angle to a radially extending line.
  • A protected retention assembly 140, as used herein, means a construct that protects another retention assembly that includes a tension member or an elongated member such as, but not limited to the trapping retention assembly limiter strap 122 and/or the narrowing retention assembly narrowing strap 132. That is, a “protected retention assembly” does not prevent or resist a training weight assembly from moving to the first configuration, but does assist in maintaining a training weight assembly 10 temporarily coupled to sport equipment 1 because it protects a tension member/strap from wear and tear and/or accidental release. Further, in at least one configuration, a “protected retention assembly” substantially encloses all of a tension member/strap. Thus, a belt loop or belt buckle is not a “protected retention assembly” because such a construct does not substantially encloses all of a belt. Further, as used herein, the backing material on a hook-and-loop coupling (or the construct to which the backing is mounted) is not a “protected retention assembly” because the backing material/mounting does not protect the tension member from wear and tear and/or accidental release. That is, if, for example the backing material/mounting catches on another object, the backing material/mounting does not resist separation of the hook-and-loop coupling.
  • In an exemplary embodiment, the protected retention assembly 140 includes a hidden pocket channel 142. That is, the first body 22 and/or the second body 24 define an interior channel or passage 144. Another retention assembly, such as, but not limited to, the trapping retention assembly 120 and/or the narrowing retention assembly 130, is substantially disposed within the protected retention assembly 140 in at least one configuration of the first body 22 and the second body 24. In this configuration, the trapping retention assembly 120 and/or the narrowing retention assembly 130 is protected by the protected retention assembly 140 and is less likely to allow the first body 22 and the second body 24 to move into the first configuration.
  • In another exemplary embodiment, the narrowing retention assembly 130 also acts as a biasing retention assembly 146. As used herein, a biasing retention assembly 146 applies bias to the sport equipment 1 when the first body 22 and the second body 24 are in the second configuration. The bias helps maintains the training weight assembly 10 at one location along the sport equipment shaft 3 and resists vibration of the training weight assembly 10. Thus, the biasing retention assembly 146 helps to retain the training weight assembly 10 in the sport equipment 1. In an exemplary embodiment, the biasing retention assembly 146 includes a retention assembly narrowing strap 132 that is slightly longer than the associated protected retention assembly passage 142. In this configuration, and when the first body 22 and the second body 24 are in the second configuration, the narrowing retention assembly narrowing strap 132 does not move entirely into the protected retention assembly passage 142. The portion of the narrowing retention assembly narrowing strap 132 that does not fit within the protected retention assembly passage 142 bows in toward the shaft passage 18 and applies bias to the sport equipment shaft 3 or the pliable material 19 (which, in turn, applies bias to the sport equipment shaft 3).
  • The number of manual retention assemblies 150 are selected from the group including, consisting of, or consisting essentially of, elastic retention assemblies 160 (FIG. 7), actuatable retention assemblies 170 (FIG. 8), and wrap around retention assemblies 180 (shown in ghost in FIG. 5).
  • In an exemplary embodiment, shown in FIG. 7, an elastic retention assembly 160 includes a first mount 162 disposed on the first body 22 and, in one embodiment, at the first body second end 30, a second mount 164 disposed on the second body 24 and, in one embodiment at the second body second end 44, and an elastic member 166. As shown, the first mount 162 and the second mount 164 are structured to, and do, define a latch 168, such as but not limited to a cantilever member 169 for the elastic member 166. The elastic member 166 is temporarily coupled, temporarily directly coupled, or temporarily fixed to the first mount 162 and the second mount 164 when the first body 22 and the second body 24 are in the second configuration. In an alternate embodiment, the elastic member 166 is permanently coupled, directly coupled, or fixed to one of the first mount 162 and the second mount 164. It is noted that, as the elastic member 166 extends across the interface of the first body 22 and the second body 24 a shaft 3 cannot move passed the elastic member 166. That is, if the elastic member 166 is in place on the first mount 162 and the second mount 164, and a user moves the first body 22 and the second body 24 to the first configuration, a shaft 3 still cannot move through the gap between the first body 22 and the second body 24 because the elastic member 166 extends across the gap. Thus, the elastic retention assembly 166 is structured to, and does, maintain the training weight assembly 10 temporarily coupled to the sport equipment 1. Only when the elastic member 166 is disengaged can the shaft 3 move through the gap between the first body 22 and the second body 24. In other embodiments, the first mount 162 and the second mount 164 are substantially similar to the radial surface channels 13, 15 described above and the elastic member 166 is disposed in the radial surface channels 13, 15 when the first body 22 and the second body 24 are in the second configuration.
  • In an exemplary embodiment, the actuatable retention assembly 170 includes a first component 172 and a second component 174 that are structured to be, and are, coupled together. The actuatable retention assembly first component 172 is, in an exemplary embodiment, coupled, directly coupled, or fixed to the first body 22. Similarly, in an exemplary embodiment, the actuatable retention assembly second component 174 is coupled, directly coupled, or fixed to the second body 24. Unlike the close-to-engage retention assembly 100, described above, an actuatable retention assembly 170, FIG. 6, requires actuation by the user. For example, the actuatable retention assembly 170 shown includes a labyrinthine retention assembly 90 as discussed above with the following enhancements. The extension 92 from the first body second end radially extending surface 31 includes an axially extending passage 176 (the actuatable retention assembly first component 172). Further, an axially extending, movable pin 178 (the actuatable retention assembly second component 174) is movably disposed in passages (not numbered) in the second body second end 44. When the first body 22 and the second body 24 are in the second configuration, the movable pin 178 is aligned with the passage 176. A user actuates the movable pin 178 which is moved into the passage 176. In another embodiment, the actuatable retention assemblies 170 include a “quarter turn to open” coupling 179, shown in FIGS. 8 and 8A. In another embodiment, not shown, the actuatable retention assembly 170 includes a buckle disposed at the interface of the first body 22 and second body 24.
  • A wrap around retention assembly 180, shown in ghost in FIG. 5, is structured to be, and is, wrapped about the radial, or outer, surface of the mass assembly 20. Unlike the arcuate leaf spring 78 described above, a “wrap around retention assembly” 180, as used herein, means a construct that has a first end and a second end which are coupled. In an exemplary embodiment, the wrap around retention assembly 180 includes radial surface channels 13, 15, as described above, as well as a belt 182. The belt 182 is disposed in the radial surface channels 13, 15. The belt 182 includes a first end 184 and a second end 186. The belt first end 184 is structured to be, and is, temporarily coupled, temporarily directly coupled, or temporarily fixed to the belt second end 186. In one embodiment, the belt first end 184 includes a “hook” material and the belt second end 186 includes a “loop” material. The belt ends 184, 186 are temporarily coupled by coupling the hook-and-loop material.
  • The multi-function retention assembly 50 includes any combination of the automatic retention assemblies 60 and manual retention assemblies 150 described above, so long as there are three or more retention assemblies 60, 150. In an exemplary embodiment, the multi-function retention assembly 50 includes a close-to-engage retention assembly 100, a trapping retention assembly 120, a narrowing retention assembly 130 and a protected retention assembly 140. In an embodiment with a four-function retention assembly 50, there are four of more retention assemblies 60, 150. In a five-function retention assembly 50, there are five of more retention assemblies 60, 150. In an exemplary embodiment, the multi-function retention assembly 50 includes only automatic retention assemblies 60. That is, the multi-function retention assembly 50 includes a combination of at least three of a spring retention assembly 70, a magnetic retention assembly 80, a close-to-engage retention assembly 100, a trapping retention assembly 120, a narrowing retention assembly 130 and a protected retention assembly 140. Stated alternately, the multi-function retention assembly 50 includes at least three retention assemblies selected from the group including a close-to-engage retention assembly 100, a trapping retention assembly 120, a narrowing retention assembly 130, and a protected retention assembly 140. In another exemplary embodiment, the multi-function retention assembly 50 includes a spring retention assembly 70, a magnetic retention assembly 80, a labyrinthine retention assembly 90, and a close-to-engage retention assembly 100.
  • While specific embodiments of the invention have been described in detail, it will be appreciated by those skilled in the art that various modifications and alternatives to those details could be developed in light of the overall teachings of the disclosure. Accordingly, the particular arrangements disclosed are meant to be illustrative only and not limiting as to the scope of invention which is to be given the full breadth of the claims appended and any and all equivalents thereof.
