Description

The invention relates to a device for retaining free loose ends of tightening or fastening straps or belts, or the like, according to the preamble of claim 1.
The above condition is frequently found in all those articles for wearing, particularly in sportswear, which have adjustment or tightening belts and/or harnesses. The loose portion of the straps, beyond the tightening or fastening portion, may sometimes cause trouble, particularly in harnesses for scuba buoyancy compensators. As is known, a buoyancy compensator vest typically consists of an inflatable bladder, which is fastened by means of harnesses and a waist belt. Each harness typically includes a strap segment which is permanently anchored by one end thereof to a portion of the vest waist. This strap typically has a buckle in an intermediate point of its length, for connection to a padded portion of the harness which corresponds to the shoulder of a user. The loose portion of the strap, which extends downwards from said buckle, when the diver is in a standing position, may be grasped by the user to tighten the harness. To this end, at each free loose end of each strap of each harness, a ring-like tightener is provided, which improves finishing and allows an easier grasp even when thick neoprene gloves are used. During diving, this loose portion of the strap may be dangerous, as the ring may get entangled or hit the mask glass, or anyway cause disturbance in an inherently difficult situation.
In order to obviate this drawback, certain types of buoyancy compensators have two waist pockets, each for receiving one free loose end of the strap of each harness, to prevent the latter from causing trouble during diving. Nevertheless, when the harness needs to be adjusted while diving, this free end is to be extracted from the pockets to be grasped, which may not be an easy operation, particularly when the diver wears thick diving gloves.
The document US 5,451,121 describes a buoyancy compensator having adjustable combination strap means forming a combination shoulder strap and belt strap means with releasable strap retaining means in order to minimize the effects on the body and waist of a diver caused by the inflation and deflation of the bladder of the buoyancy compensator.
In the buoyancy object of the invention only the ends of the belt straps pass respectively through a second retaining loop. Finally the ends are then looped respectively around a pull ring to which the ends are secured as by stitching.
The document US 5,860,769 describes a buoyancy compensator which is provided with a polyangular or triangular holder that distributes the weight of a load between the waist, back and shoulders of a user. Moreover the triangular holder is provided in combination with another device (the swivel buckle) that improve the wearability of the buoyancy compensator.
The triangular holder has a generally triangular configuration and it has been designed in order to improve the comfort and the hydrodynamics of a diver thank to the fact that the buoyancy compensator is maintained close to the body of a diver.
In order to assure the support of the load it is obvious that the triangular opening is not such as to allow the insertion of the free strap.
The document EP 853 037 shows a support garment for diving equipment that includes adjustment strap provided with a classic D ring around which the strap is stitched for accommodating various body sizes.
The document US 6,056,625 describes a highly compact and flat slider for brassiere straps which has improved capacity for retaining the originally set position and tension. The adjustable strap slide comprises a pair of longitudinal frame limbs (11,12) delimiting a oval slot (15,16) with a crossbar (17). The features of the slider have been provide for obteining a perfect adjustement of the brassiere strap and it is evident that the above mentioned device can work only if the straps are tensioned/released.
The document US 2,022,483 describes a buckle for securing the end of a sanitary pad. The buckle in rigid material is in the form of an oblong frame provided with a straight long side for attachment to one of suspender element, the opposite long side is preferably curved. An elongate opening is formed in the buckle adjacent to the straight side and a shorter elongated opening is provided adjacent to the curved side. The two openings are separated by means of a gripper bar with teeth extended into the openings.
The document FR 2490081 describes a device for adjusting the length of the straps.
The device comprises a strap and a regulation device with a shape such as, when a traction force is applied on the free end of the strap, said regulation device rotates around the longitudinal branch so that the strap is blocked in the longitudinal slit.
Particularly the regulation device has a rectangular shape and comprises two slits, one intermediate branch with a nick for facilitating the introduction of the strap and two lateral branches.
The lateral branch is fastened to the end of the strap while the free end of said strap passes through the slit. When a force is applied, the strap fits against both sides (entrance and exit) of the slit.
For facilitating the fitting, the slit has a sharp corners and a bearing is provided around at least part of the circumference of said slit.
The width of the slit is similar to the width of the strap or the slit has a specific width in order to fit the strap.
The document US 3,077,650 describes a connector means with a semicircular aperture bounded by the confronting curved or arcuate portion and straight portion having a transverse slot therethrough. These means are used for connecting a pair of unequal width strap portions of an adjustable shoulder strap.
The document US 2,643,431 describes an adjustable shoulder strap and a buckle assembly.
The buckle is stamped from a rigid piece of metal or the like and includes a pair of spaced vertically extended side arms. The bottom ends of the side arms are joined by a bottom arm which is slightly downwardly arched. An intermediate portion of the lower strap is passed over the top edge of the bottom arm, and has its free ends secured to the top edge of the article of lingerie.
The top of the buckle is closed by a pair of bar portions.
The effective length of the bottom arm of the buckle is just slightly less than the width of the lower strap so that the lower strap passes over that bottom arm with some slight bunching.
The lower end of the upper strap is first passed behind the upper bar portions then beneath the bottom edge of the lower cross bar, then upward between the adjacent edges of the cross bars. The free end of the upper strap is then passed upward in front the crossbar and out behind the rear face of the portion of the upper strap which passes behind the upper bar portion. With that arrangement the effective length of the upper strap can be adjusted to adjust the total length of the shoulder strap assembly to support the article of lingerie at the desired position on the body.
Therefore, this invention has the object of obviating the above drawbacks and allowing, by simple and inexpensive means, to provide an article for wearing, particularly a buoyancy compensator vest for underwater diving, wherein the free loose ends of harnesses or other belts may be secured in such a manner that they are of no hindrance upon diving, while being easily reachable by the user for adjustment purposes. Yet, as is better explained below, the object of this invention is to solve the problem of securing the free loose ends of tightening or fastening straps or belts in a much wider range of articles, particularly sportswear, such as backpacks, pouches, bags or the like.
The invention achieves the above purposes thanks to a device according to the preamble of claim 1 and further comprising the contents of the features of the characterizing part of claim 1.
In accordance with a first arrangement, the opening of the widened fastener and retainer member may be such that, when the free loose end of the strap or belt segment is inserted in the opening, it causes this free loose end to pass from one side of the connecting portion of the strap or belt segment to the opposite side of said connecting portion of the strap or belt segment.
This opening may either be substantially on the same plane as the two faces of the connecting portion of the strap or belt segment, or extend transverse, particularly perpendicular, to the longitudinal extension of this connecting portion of the strap or belt segment.
Alternatively, the widened fastener and retainer member may coincide with the widened fastening end of the strap or belt segment. Back to the buoyancy compensator vest, the strap may be arranged to have an increasing width toward the end for connection to the waist portion of the vest, at least for the portion in the proximity thereof, in which portion a transverse slot may be provided, in which the user may introduce the free loose end of the strap segment.
Nevertheless, according to a preferred embodiment of the invention, this widened fastener and retainer member is fixed to the first part of the article along a its portion while, along the opposite portion it is fastened to an end of the strap or belt segment.
The fastening end of the strap or belt segment may have a portion that is bent back and sewn on itself as a hem, that encircles a longitudinal branch.
The widened fastener and retainer member may be secured to the first part of the article by means of a strap or belt segment which is fixed, and particularly sewn, by one end, to the first part of the article, whereas at the opposite end it has a portion that is bent back and sewn on itself as a hem which encircles the other longitudinal branch of the member.
The strap or belt segment that secures the member to the first part of the article may have such a length that the ring is situated near the edge of this first part. In this case, the seam of the hem may advantageously correspond to the seam whereby the strap is secured to the first part of the article. Alternatively, it may be longer and such that the member is situated in an intermediate position between the first and second part of the article.
According to a preferred embodiment, that will be described in greater detail in the description of the drawings, at least one, but preferably both longitudinal branches may have an intermediate longitudinal slit, which divides the branches into two parallel longitudinal portions, one of which, preferably the external portion, is respectively encircled by the hem at the fastening end of the strap or belt segment and by the hem at the end of the strap or belt segment which is designed to secure the retainer member to the first part of the article. This avoids the presence of other strap portions, when the free loose end of the strap passes in or out of the member, and prevents any mutual interference.
According to an improvement, at least one, particularly both longitudinal branches may have two parallel longitudinal slits, which divide the branches into three longitudinal parallel portions, one of which, preferably the intermediate portion, is respectively encircled by the hem at the fastening end of the strap or belt segment and by the hem at the end of the strap or belt segment which is designed to secure the widened retainer device to the first part of the article.
According to yet another improvement, at least one, but preferably both longitudinal portions respectively encircled by the two hems, may have an opening, particularly an intermediate opening, for insertion of the branch inside its respective hem. Thanks to this arrangement, the device may be secured when the hem has already been sewn, in a separate processing step, and more advantageously, if the ring is broken, it can be replaced without having to unpick the hem.
The opening may be relatively short as compared with the total longitudinal extension of the portion encircled by the hem and of the hem itself, so as to allow the introduction of the device portion with the intermediate opening inside the hem, while preventing this portion from accidentally coming out of the hem.
Regardless of the embodiment being implemented, means may be provided for preventing the free loose end of the strap from accidentally coming out of the opening of the widened fastener and retainer member, when it is inserted therein.
As mentioned above, the free loose end of the strap may have manual grasping means for easily tightening and/or fastening the strap which, in the case of the buoyancy compensator harness, typically consist of a D-ring, whose straight portion is secured to the free loose end of the strap segment.
the widened fastener and retainer member may consist of a fastening plate which is secured by one edge to the first part of the article, by sewing and/or chemical-physical adhesion and/or the like, whereas it is secured by the opposite edge and still by sewing and/or chemical-physical adhesion and/or the like, to the fastening end of the strap or belt segment.
This fastening plate has the shape of a trapezium, particularly an isosceles trapezium, with the greater base corresponding to the edge secured to the first part of the article, particularly the waist portion of the buoyancy compensator vest, and the smaller base corresponding to the edge secured to the strap or belt segment. The opening for receiving the free loose end of the strap or belt segment may be an elongated slot extending parallel to the two bases and in an intermediate position therebetween, particularly near the greater base, and is substantially as long as the strap segment is wide.
Advantageously, the fastening plate may be made of a relatively rigid material such as metal, leather, thick fabric, or the like. According to a preferred arrangement, the plate may be made of a plastic material and have such a thickness as to be relatively resilient, to be elastically deformable by the user's manual pressure of at least the slot edge facing toward the edge secured to the strap segment end, to allow and/or facilitate the passage inside the slot of the other free loose end of the strap or belt segment. The slot may have a width greater than or equal to the thickness of the strap segment, but preferably slightly lower than it, so that the two longitudinal edges of this slot exert a retention action, to prevent the free loose end of the strap segment from accidentally coming out of the slot when it is inserted therein.
The slot may have such a size as to allow an easy passage of the D-ring, particularly it may be narrow in the middle and widened at the opposite ends, particularly toward the fastening edge of the strap segment, in such a manner that the slot edge facing toward the fastening end of the strap segment has an intermediate tongue that is designed to yield upon insertion of the D-ring in the slot or upon intentional extraction of the D-ring from the slot, and forms an intermediate retaining narrowed portion, to prevent the free end of the strap segment with the D-ring from accidentally coming out of the slot.
Regardless of the embodiment being implemented, the strap or belt segment may be connected to the second part, particularly in the case of harnesses, by buckle means, in such a manner as to adjust the position of these buckle means along the longitudinal extension of the strap or belt segment, to allow the strap or belt segment to be tightened and/or fastened, and in this specific case to allow harness length adjustment.
Advantageously, the strap or belt segment may be connected to a first buckle part, which is engaged, particularly snap-fitted, with a second buckle part associated to the second part of the article, particularly the padded harness portion, in such a manner that the first and second part of the article are connected in a removable manner. In the particular case of the buoyancy compensator vest, this arrangement allows the padded portion to be detached from the waist portion of the vest to facilitate wearing/removal thereof.
The buckle or the second buckle part may be connected to the second part of the article in an indirect manner, i.e. by means of a second strap or belt segment, particularly to adjust its position along the longitudinal extension of said second strap or belt segment. The end of the second strap or belt segment which secures it to the second part may advantageously be itself equipped with a retainer device as described in one of the above embodiments. Back to the buoyancy compensator vest, this invention may also find an advantageous application with reference to the two free loose strap portions that typically project in two opposite directions from an intermediate buckle of the waist belt and are manually tightened by the diver for belt adjustment. The end of each strap segment that forms the belt, to be secured to the waist of the vest may be equipped with a device as described in one of the above embodiments, in which each free loose end of the strap is to be introduced to prevent it from causing trouble during diving.
The advantages of the invention are self-evident from the above disclosure, particularly when the invention is used for a diving buoyancy compensator vest. The free loose ends of each harness may be easily introduced in the slot provided in their respective fastening plates to be passed directly inside the vest, so as to cause no trouble during diving. Also, when the harness needs to be tightened, the user may easily introduce a hand in his/her vest and tighten the harness without having to extract the free end of the strap from the slot.
Further characteristics and improvements will form the subject of the dependent claims.
The characteristics of the invention and the advantages derived therefrom will be more apparent from the following detailed description of the annexed drawings, in which:

Figure 1 is a perspective view of a buoyancy compensator vest for underwater diving, having a device according to the invention and particularly a device as shown in Figures 2 and 3.

Fig. 6 shows the area in which the ring-like tightener is engaged with the free loose end of the strap of a harness or a general tightening strap.
Fig. 7 shows that the D-ring that is used in Figures 4 to 6.

Referring to the figures, a buoyancy compensator vest for underwater diving typically includes an inflatable bladder that is worn and secured to the user's trunk by means of two harnesses 2 and at least one front waist belt 3. Each harness 2 has a padded portion 102 that corresponds to a shoulder when the vest is worn by a user. The padded portion 102 has a buckle 4 at the front for connecting and tightening a strap segment 5 which is fastened at one end to a waist portion 101 of the bladder 1. The portion of the buckle 4 designed for connection to the strap 5 has an end with two longitudinal openings 104, 204 disposed transverse to the longitudinal extension of the strap segment 5 and are separated by a member 304. First, the free end of the strap segment 5 is passed in the opening 104 closer to the padded portion 102 of the harness 2 from the inside of the buckle 4, then it is guided around the member 304 and further inserted in the other opening 204 so that the strap segment 5 is divided into two portions, one of which 105 is used to connect the waist 101 of the bladder 1 to the buckle 4, therefore to the padded portion 102 of the harness 2, and the other 205 projects from the front side, when the vest is worn by a standing user, so that it can be grasped by a hand and tightened to adjust the harness 2. In order to facilitate grasping, a ring 6 is provided at the free end of the portion 205 of the strap 5, particularly a rectangular or a D-ring, which is typically made of plastic or stainless steel, in which the user may insert a thumb even when he wears thick neoprene gloves. The above described fastening portion of the buckle 4 may be part of a one-piece buckle 4 which is directly secured, at the edge opposite to the one for connection to the strap 5, to the padded portion 102 of the harness 2, for instance by sewing. As an alternative, this fastening portion of the buckle 4 may be a part of a male member 404, which has engagement/release means, particularly by snap engagement, in a female member 504, which is in turn secured to the padded portion 102 of the harness 2. The above buckle types are both widely known and used in sportswear and equipment, such as backpacks or the like. Nevertheless, any other fastener or tightener buckle may be used, or the male part 404 and the female part 504 of the buckle 4 may be simply disposed in reversed positions.
The end of the strap 5 to be secured to the waist 101 of the bladder 1 has a member for securing the strap 5 to the bladder 1, whose representation in Figure 1 refers to Figures 2 and 3, and consists of a plate 7 with a slot for the passage of the D-ring and of the loose end of the associated strap whereto this ring is attached.
The longitudinal extension of the opening may be longer than the transverse extension of the D-ring, designated with numeral 6, or the diagonal extension may be longer than the D-ring 6, so as to advantageously allow the passage of the D-ring 6 through the opening while preventing the D-ring 6 from passing in a position parallel to the longitudinal median axis of the . The member 7 is composed of a pair of parallel longitudinal branches which are interconnected at each pair of corresponding ends by a portion that is substantially polygonal .
Here, each of the two longer branches is engaged in a hem 305 provided at the fastening end of the strap segment 5 and in a hem 9 formed by a short length of strap folded on itself and sewn onto the edge of the waist 101 of the bladder 1.
Each of the two longitudinal branches may havea longitudinal intermediate slot which divides it into two branches, the outermost of which may be encircled respectively by a hem 305 provided at the fastening end of the strap segment 5 and by a hem 9 formed by a short length of the strap folded on itself and sewn onto the upper edge of the waist 101 of the bladder 1. As is clearly shown in the Figures, the free loose end 205 of the strap 5, ending with the D-ring 6, may be easily introduced from the outside into the member 7 and directly passed into the bladder 1 to prevent it from causing trouble during diving.
In all the above embodiments, for any adjustment requirement, the diver need only introduce his/her hand into the bladder 1 and tighten the strap without being forced to extract the free portion 205 out of the bladder.
A embodiment of the inventive device consists of a fastening plate 7, particularly having the shape of an isosceles trapezium which is secured to the upper edge of the waist portion 101 of the bladder by the greater base, by sewing or the like, and is secured to an end of the strap segment 5 by the smaller base 207, still by sewing or the like. At the edge 107, the plate 7 has a slot 307 which extends parallel to the edge 107 and transverse to the longitudinal extension of the strap segment 5. During use, the free loose end of the portion 205 of the strap 5, beyond the buckle 4, which might cause trouble during diving, may be easily introduced in the slot 307 and passed into the vest, as indicated by the arrow, where it is easily reachable by the hand of the user to be possibly further tightened from the inside of the vest, without requiring to be extracted out of the vest. The edge of the slot 307 facing the shorter base 207 has an intermediate tongue 407 formed by an intermediate narrower portion of the slot 307, which tongue 407 may yield upon passage of the ring-like tightener 6, whereby it has the function of preventing any accidental extraction of this ring-like tightener 6. To this end, the plate 7 may be made of a relatively rigid and elastic material, particularly plastic. Thanks to this arrangement, the free ends of the straps 5 of the harnesses 2 are safely held inside the bladder 1, in a position that is easily reachable by the user.
It shall be noted that the above described embodiments shall be intended without limitation, as preferred examples, the device addressed by the invention being also advantageously applicable, for instance, to the waist belt 3 or other belts of the vest. In fact, the waist belt 3 itself has at least one free loose strap portion 103, but typically two free portions 103 which are tightened by the user from opposite sides, to adjust the belt 3. A device as described in one of the above embodiments may be provided at each opposite area in which the belt 3 is secured to the two waist and side portions 101 of the bladder 1, allowing to pass the free loose ends of the belt 3 into the bladder or simply to secure them. The field of application of the invention itself shall not be limited to the buoyancy compensator vest for underwater diving, as the invention may find advantageous applications in straps or belts for tightening several types of articles, particularly sportswear, such as backpacks, pouches, bags, or the like. The above embodiments themselves shall be intended without limitation, as the guiding principle of this invention is applicable to a variety of embodiments. As a mere example, the connecting strap may be a segment of a string or the like or a fastening member may be provided, which has a circular aperture for receiving the free loose end of this string segment, which may possibly have a ball-like grasp member with a slightly greater diameter than the aperture, which member may be introduced therein thanks to the resilience of the edge of the aperture, which has the additional function to prevent it from being accidentally extracted therefrom.
Back to the Figures, and with particular reference to Figures 4 to 7, each D-ring 6 is fastened to the free end of its respective portion 205 of the strap 5 by wrapping the latter around the straight portion 106 of the D-ring 6, by bending it back on itself and sewing it, to form a hem 305 for receiving this straight portion 106 of the D-ring 6. In certain conditions, particularly when the D-ring 6 needs to be replaced, this arrangement is very uncomfortable, as the hem 305 is to be unpicked and sewn each time. According to another characteristic of the invention, these D-rings 6 may be made in such a manner that they do not need to be mounted before sewing the end of the portion 205 of the strap 5 on itself to form the hem 305. To this end, the invention proposes a novel D-ring wherein, in an intermediate position between the straight portion 106 of the D-ring and the opposite side of the ring 6, particularly adjacent to said straight portion 106 and at a slightly greater distance with respect to the thickness of the strap 5, a segment is provided that is divided into two portions by an intermediate opening for insertion into the hem 305 which opening is relatively short as compared with the whole length of the hem 305. By this arrangement, the D-ring 6 may be fastened to the end of the strap 5 when the hem 305 has already been sewn, which allows a considerable simplification as regards construction. Moreover, the replacement of D-rings does not require hems 305 to be unpicked, and special tools to be used. Here, the straight portion 106 of the ring 6 has the function of providing the ring 6 with a certain rigidity and however, in certain cases, the opening for insertion into the hem 305 may be situated in an intermediate position of the straight portion 106. The above arrangement may be obviously be advantageously used for buckle fastening ends or the like. It may be particularly used for the trapezoidal plate, which may have the fastening characteristics of the D-ring. The broken portion may be either the outermost or the innermost delimiting portion of the slot. In the first case, an additional bracket or U-shaped segment may be connected to the ring from the outside, which has the same stiffening function as the member 106 of the ring 6. In the second case, the function of the member 106 is accomplished by the outermost delimiting portion of the slot. The above may be provided as regards the attachment of the reteiner device 7 both to the hem 305 and to the hem 9.
Obviously, the invention is not limited to the embodiments described and illustrated herein, but may be greatly varied, both as regards construction and with reference to the field of application, without departure from the guiding principle disclosed above and claimed below.
