A POLE CLIMBING ANI) FALL RESTRAINT DEVICE AND KIT
CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims the benefit under 35 U.S.C. 119(e) of tJ.S.
Provisional Patent Application Serial No. 61/103,961 which was filed on October 9,2008.
FIELD OF INVENTION
The present iilvention relates to pole eiiinbing and fall restraint safety harnesses, safety belts aud the like that are worn to prevent falls.
BACICGROUND OF THE INVENTION
Safety restraint devices tised to prevent falls are often used by workers or hunters to prevent accidents or injury when climbing tall objects such as trees or utility poles. Examples of such safety devices are disclosed in U.S_ Patent Nos. 4,923,048, 4,991,689, 5,052,514, 5,137,113, 6,241,045, 6,752,242 and 6,981,571. "I"liese devices typically include a belt or liarness worn by a user and a rope that has at least one end connected to the belt or harness.
Many safety restraint devices require a uscr to position a rope around the circumference of a utility pole and connect one end of the rope to another portion of the rope such that the rope foniis a loop that totally encircles the pole or trunk. Such loops are often difficult to adjifst when a user climbs up the pole beeause the rope is normally in tigit, frictional engagement with the pole. As a restilt, it is often diffcult to adjust the position of the loop as a user reaches higher positions on the pole he or she is ciinYbing. To make readjustment of the loop easier and climbing occur at a faster rate, users may disconnect the rope to reposition the loop formed by the connected rope, which increases the user's exposure to injury because the safety device is unable to prevent a fall until the rope has been reconnected by the user to reform the loop.
i-o climb tip a pole, a tiser typically inust loosen the loop fibrn its tiglit fit around the pole by providing additional rope length to introduce slack that can be taken up as the user climbs a pole. In some devices, the rope that a user must manipulate to move the loop encircling a pole has an end connected to a holder that slides along the rope, such as the devices disclosed in U.S.
Patent Nos. 4,92.3,048 and 4,991,689. If a user wishes to provide slack without disconnecting the rope, sueh sliding devices require the clirnber to iiitroduce the necessary slack into the rope by reducing the distance between the user and the pole, Such a reduction of distance is often obtained by tightly hugging the pole as the pole is climbed. Sucll hugging can slow the rate at which a user may climb the pole.
Ftu=ther, a climber must often reAdjust the position of the loop when climbing the pole.
The time needed to readjust the position of the loop inereases the time needed for the user to climb the pole. Readjustment of'the position of the loop can be difficult and sibnificantly tinie constuning due to the small diameter of the rope and its tight fit around the pole.
Some safety restraints, such as the belt disclosed in U.S. Patent No.
5,137,113, require a user to adjtist the length of the loop by manipulating a locking device located at the side of a user to an unlooked position. If the locking device is not properly reset to its locked position, the ioeking device mtty not iock the position of the rope, which caii perniit a user to accidentally fall without any ftmctioning restraint, The positioning of such devices make them difficult for a tiser to see, which can prevent the user from properly manipulating the locking device or easily verifying that the locking device has been properly reset to its locked position as the user climbs up a pole or performs worlc at a given position on Ihe pole. As a result, users often stop their work for substantial periods of time to verify that the locking device they cannot see is properly set.
Because locking devices are often not positioned directly in front of the user, the uscr normally has to turn his or her head or take other action to maneuver the user's eyes so the user can see the locking device. Dtie to the fear of fafling, sucll verification can occur nlultiple times when working on a project, wliich inay greatly increase the titne needed to complete a task or project. The concerns related to the setting of the locking device may linger with a tlser as he or she performs the work, which can impair the user's ability to perform his or her work. For example, such lingering concern can detrirnentally affect the clttality of the work being performed 1nd the time needed to perform such work. Such concerns are typically lieightened if a user mtrst make substantial movements to verify the setting of the locking device because such substantial movements cotild cause the user to fall while the user is not ceitain the locking device is properly set to prevent such a fall.
A pole clirnbing and fall restraint device is needed that permits a user to easily reposition the loop surrounciing a pole as he or she climbs the pole. Preferably, such a device should also be configured to permit a user to easily adjust the length of the loop by manipulating a locking device, 7'lie locking device shotild be positioned so it can easily be seen by a ttser as he or she climbs a pole or performs work at a given position on a pole so the user can duickly and easily verify the locking device is set to lock the rope forming the loop.

DF'FAILCD DESCRIPTION OF I'RESENT PRFFFRRrD EMBODIMENTS
A first pt-esent pre.ferred emboditnent I of my pole c[iinbing and fall restraint device is sliown in Figures 1-5. The embodiment I has a belt 3 that has a rear portion 7 and a front portion 5. The belt 3 also has a belt buckle 19 at the middle front portion 6 of the belt. The belt has a first connector 9 attached to the belt adjacent to the first side of the belt buckle and has a second connector I I attached to the belt.3 ad,jacent to an opposite second side of'the belt buckle. A first strap 17 extertds from the first connector 9 to a third connector 13. A second strap 15 extends from the second conneetor 1 I to the third connector 13. A locking device 18 is connected to the third connector_ The second strap 15 and first strap 17 connect the thircl connector 13 and the locking device 18 to the belt 3. Rope 20 passes through the locking device 18.
1 prefer that connectors 9 and 11 be D rings and that connector 13 be a triple lock carabiner. Of course, various other fasteners or connectors inay also be used.
The locking device 18 has a cam 24 that has teeth 26 configured to engage the rope 20.
When the locking device 18 is n3oved to a locked position, shown in higure 4, the teeth 26 of the cam 24 engage the i-ope 20, preventing the rope from moving through the cam.
When the locking device is an unlocked position, shown in Figure 3, the rope may pass through the locking device.
The rope 20 has a first end 23, a middle portion 21 and a second end 22. A
clip 25 is attached to the first end 23 of the rope. The clip 25 is configured to connect to the middle portion 21 of the rope such that the clip 25 can slide along the middle portion 21 of the rope.
A first liandle 27 and a second handle 31 are attached to the iniddle portion 21 of the rope. The first handle lias a hand grasping niember 28 and a tube 29 that has a bore sized and configured to slidably receive the rope 20. Tube 29 permits a user to niove the tirst handle 27 along the middle portion 2I of the rope. The second hAndle 31 also has a grasping member 30 and a tube 32. Tube 32 has a bore that is sized and configured to slidably receive the rope 20 so a user can move the second liandle 31 along the niicldle porlion 21 of the rope, Tubes 29 and 32 tnay be coti7posed of plastic, leather, canvas or any combination thereof. I
prefer to attach aNvear pad 33 to cach tube, whicli presses against a pole being clirnbed.
When n user c[imbs a pole, the tiser places the first end 23 of the rope around the pole and attaches clip 25 to the middle portion of the rope such that the rope forms a loop around the pole.
As a user clin7bs up the pole, (he loop acts as a restraint to prevent the user fi-om falling from the pole. Wlien the usei reaches a particular position on the pole, the user may stop clinlbing to perform work at that position. When performing work on a pole, a user typically leans away froni the pole to ensure the loop is in a tight, frictional engagement with the pole so the user can easily maintain liis or her pasition on the pole.
Preferably, the first strap 17 and second strap 15 extenci to a position adjacent to and forward of the middle portion 6 of the belt 3 so that the position of the locking device 18 is forward to and adjacent to tlie niiddle of the belt. Such a position allows a user to easily see the locking device 18 so that the user can easily nianipulate the loclcing device 18 or verify that the locking device 18 is in a locked or an unlocked position.
Most preferably, the first connector 9 and the second connector 11 are equidistant from the buckle 19 and the first strap 17 and second 15 strap extend a substrlntially equal distance from tlieir respective connectors 9, 11 to position the locking device 18 adjacent to and forward of the front middle portion 6 of the he1t. Such positioning ensttres the stress frorn the rope and locking device is equally distribtited on botli sides of the belt so a user can work while maintaining a conlfortable position, such as the position illtistrated in Figure 5, when on a pole 36. Pole.36 may be a tree trtink, a utilit,y pole, or any other tall elongated body.
It sllould be appreciated that an equal distribution of force makes it easier ftor a user to maintain his or her balance and position on a pole and prevents the user from assuming an uncornfortable posture wliile performing work while on the pole. For example, the equal distribution of force to botli sides of the belt prevents a user from having to compensate fora dispropor-tionate aniount of stress that may be distributed along one of the two straps by leaning toward the other strap or taking some other corrective ac,tion to maintain a stable position while working on a pole.
The forward and central positioning of the locking device relative to the user also permits a user to eEisily see and operate the locking device without having to subsiantially move his or her body to see the loclcing device. A user working on a utility pole, for example, should only have to lower his or her head to observe the loclcing device to verify it is in the locked position or to see the locking device 18 when ad,justing the length of rope 20 e:ctending from a side of the locking clevice 18. Suclt a head movement is niuch simpler and requires nluch less movenlent than the rnovements required by the positioning of locking devices in other safety restraints, wlaich often require the user to twist his or her head to the right or left to see the locking device.
The position of the locking device 18 of device 1 is maintained in substantially the same location so that a user can easily find the device or deterrnine the location of the lor.king device.
Otller devices often have locking devices or rope corutecting mechanisms that are moveable along thc rope, belt, or harness so that a user must move his or her head in various, and sonietimes uncorrifortable, locations to see the locking device. Tlrc prc;dictable or kiiown position of ihe locking device 18 of'device I helps to greatly redtiee, if not eliminate, any concern the tiser may havc regarding the locked or unlocked status of'the locking device while working on a pole. For instance, a user should not have to rnalce any substantial movements to tind and observe the locking device 18 of device 1, which can alleviate, if not eliminate, some concerns a worker niay hnve about verifying the setting of the locking device.
I-landles 27 and .31 permit a user climbing a pole to climb at a quicker rate.
Further, the handle s permit a user to clinib up or down a pole rnore efficiently than other devices, For example, a user need not waste energy attempting to grab part of the loop that sun-ounds a pole while clinibing or descend'uig to readjust the position of the loop, whicli is often diftictilt and tinie consuming because of the loop's tight engagement with the pole and the srnall diameter of the rope. 7he liandles permit a user to easily readjust the position of the loop by grabbing the grasping members 2$, 30 of the respective handles to pull the loop upwards or downwards to"
reposition the loop. Of cotu-se, a user may only need to grab one of the grasping members to effectively reposition the loop, which rec3uires much less tiine and effort than attempting to grab a part of the loop. Moreover, the adjitstability of the handles allows a user to alter the position of the handles 27 or 31 to make repositioning the loop easier. For instance, tubes 29 and 32 permit a user to slide one or both handles along the middlc portion 21 of the rope away from or toward the first end 23 of the rape to place the handles in a desired position.
Wear pads 33 niay be attached to the tubes to increase the durability of the handlcs. The wear pads are preferably made of leather or canvas, but may be made ol'otlier materials as well.
As may best be appreciated in Figure 5, the wear pads are connected to the tubes so that the wear pads engage the pole being climbed by the user.
It should be undersfiood that the teeth 26 of the cam 24 of the locking device 18 can be configtired to permit the cope 20 to pass through the locking device 18 in a first direction when the locking device 18 is in the locked position, but prevent the rope from passing through the locking device in an opposite second direction. The first direction is preferably toward the first end 2.3 of`the rope so that the user does not have to manipulate the locking device to obtain additional slack for tlie loop as lre or she climbs tip a pole. For such enibodiments of my device, the second end 22 of the rope prefeiably has a large knot or stop that prevents the second end from passing through the locking device. Of course, other embodiments may llave a locking device that prevents the rope fi-om passing throtigh any part of the locking device when the locking device is in the locked position.
The handles 27 and 31 may be interconnected by an adjustable fotirth strap 34, as may best be seen in Pigure 2. It should be understood that other embodiments may liave only one handte adjustably connected to the rope 20. In yet other embodiments, one handle may be adjustably connected to the rope and one or more non-movable liandles may be affixed along the rope 20 stich that tlie position of the non-movable handies cannot be adjusted.
The device 1 illustrated in Figures 1-5 and other embodiments of my pole climbing and fall restraint device may be included in a ftill or partial body harness worn by a user climbing a pole oa, otlier tall elongated object. The device I and other embodiments may also be sold and worn separate frotn such liarnesses. Wlien par4 of a hamess, the belt 3 may be worn such that the belt is positioned at a user's waist, above a tiser's waist, or below a user's waist. For example, the belt 3 may be designed to be positioned on or below a user's buttocks wl-ien incorporated into a ftill body liarness.
Referling to Figures 6-7, a second present preferred embodinient 51 of my pole clinibing and fall resti-aint device is illustrAted. Embodiments of rny invention siniilar to the second present preferred embodiment 51 may be referred to as a lanyard apparatus. The lanyard apparatus inc.ludes a pole strap 52 that extends througlt a locking mechanism 58. The pole strap is sized and c.onrgured to arijustably wrap abotit a pole. The loclcing nseclianism 58 is attached to a coriilector 56. Preferably, the connector 56 is a triple lock carabiner.
The first end 53 of the pole strap 52 is attached to a coupling 55. A first liandle 91 a second handle 92 are moveably attached to the pole strap 52. 1 prefer that the handles 91 and 92 include hooks, such as J-hooks, so that a user can easily slip liis or her hand into the hook and keep the liook on the hand while climbing. Other configtirations, stich as a loop could also be used. A tirst stop 67 and a second stop 68 are also moveably attached to the pole strap 52.
The first handle 91 incfudes a Frst hook 62 and a strap 94 that attaches the Crst hook 62 to the pole strap 52. The connecting strap 94 extends from the pole strap 52 to the first Ilook 62.
The strap attaches the first hook 62 to the pole strap 52 sucli that the first hook 62 may be rotated about the pole strap 52 and rnay also be slid along the pole strap 52. A user may slide or rotate the first hook 62 independently or at the sarne time. 'The connecting strap 94 positions the first hook 62 a first distance away from the pole strap 52. Preferably, the frst distance is 8-13 inches.
Ihe second handle 92 includes the second ltook 63 and a strap 96 that atiaches the second hook 63 to the pole strap 53. The connecting strap 96 extends from the pole strap 52 to the second hook 63. The strap 96 connects the second hook 63 to the pole strap 52 such that the second hook 63 may be rotated about the pole strap 52 and may also be slid along the pole strap 52. The sliding and rotating of the second hook may be done independently or in combination.
The connectirrg strap 96 positions the second hook 63 a second distance away from the pole strap 52. Preferably, the second distance is 3-5 inches.
I have founci that liaving both hooks positioned at ditferent distances fronl the pole strap 52 helps a user readjust the pole stiap 52 as the user climbs a pole. Indeed, the hooks 62 and 63 allow a user to more easily move and readjust the pole strap 62 while climbing than handies 27 and 31, as may be appreciated from Figure 8. For example, it has been determined that a user climbing a pole can rnore easily manipulate the pole strap 52 with hooks because the hooks perrnit a tiser to manipulate the pole strap 52 without tightly holding the hooks. Preferably the liooks are cnnfigtired to open away from the pole or pole strap 52 when a user is lifting the hoolcs upward for climbing a pole. Such an orientation has been found to permit a user to easily place one or more fingers or the user's entire liand under the hooks to move the pole strap. Positioning the hooks away frorn thc pole strap 52 by the connecting straps also perniits a user to more easily find, move and grasp the liooks to adjust the position of the pole strap as the user clinibs a pole.
The first stop 67 is positioned between the first liook 62 and the second hook 63. The first stop 67 is configured to help stop movement of the first and second hooks 62 and 63 along the pole strap 52 to prevent the hooks from both being positioned next to each nther. Such a position has been found to help avoid situations where a user must readjust the position of one of the hooks or handles due to movement of both hooks to one side of a pole.
Positioning the first stop 67 between the first and second hooks 62 and 63 can also help prevent a user having to grab around the pole in an attenipt to find one of the hoolts that may lrave moved while the user worked or readjusted his position on a pole.
The second stop 68 is positioned along the middle portion of the pole strap 52. The second stop 68 is adjustable along the length of the pole strap and can be used as a stop or parking tap to he.lp prevent movenient of the coupling 55 while the coupling is attached to the iniddle portion of the pole strap 52. By preventing such movenient of the coupling 55, the second stop 68 can lielp prevent the pule strap 52 from becoming loosened in use so that a user stays wrapped about a pole he or she may be positioned cii and is prevented froni accidentally faliing while the use works on a pole or climbs up or down a pole.
In some cmbodiments the first stop 67 may include an engaging device 71 that is contigured to engage or pierce a pole or other structure that may be climbed.
An engaging device '71 can be particularly helpful in ensuring the pole strap 52 is properly engaging a pole that may be slick due to ice, snow or other relatively slick condition. The engaging device 71 may include a nail, screw, bolt, hook, a rough surface or at least one saw tooth. More than one engaging device 71 iuay be attached to the first stop 67. The cngaging device 71 may also be used to help attach the first stop 67 to the pole strap 52. For instance, a portion of the engaging device may be used to secure a connecting strap to the pole strap 52 while a second portion of the engaging device projects past the pole strap 52 such that the second porti.on of the engagement device can engage a pole.
In some embodiinents of the lanyard apparatus, the connector 56 or locking mechanism 58 may not be included. It is contemplated that such einbodiments of my lanyard apparatus will be configured for attachment to a pole climbing belt, or harness or otlier belt device. A
connector or locking mechanism configured for attaching the lanyard apparatus to the belt, harness or other belt device may be used to attach the lanyard apparatus to the belt hai-ness or other belt device. It is also contemplated that a belt, harness or other belt device can include such a connector or locking mechanism, The second embodiment 51 of my pole climbing and fall restraint device may also be provided in a kit.

DF'FAILCD DESCRIPTION OF I'RESENT PRFFFRRrD EMBODIMENTS
A first pt-esent pre.ferred emboditnent I of my pole c[iinbing and fall restraint device is sliown in Figures 1-5. The embodiment I has a belt 3 that has a rear portion 7 and a front portion 5. The belt 3 also has a belt buckle 19 at the middle front portion 6 of the belt. The belt has a first connector 9 attached to the belt adjacent to the first side of the belt buckle and has a second connector I I attached to the belt.3 ad,jacent to an opposite second side of'the belt buckle. A first strap 17 extertds from the first connector 9 to a third connector 13. A second strap 15 extends from the second conneetor 1 I to the third connector 13. A locking device 18 is connected to the third connector_ The second strap 15 and first strap 17 connect the thircl connector 13 and the locking device 18 to the belt 3. Rope 20 passes through the locking device 18.
1 prefer that connectors 9 and 11 be D rings and that connector 13 be a triple lock carabiner. Of course, various other fasteners or connectors inay also be used.
The locking device 18 has a cam 24 that has teeth 26 configured to engage the rope 20.
When the locking device 18 is n3oved to a locked position, shown in higure 4, the teeth 26 of the cam 24 engage the i-ope 20, preventing the rope from moving through the cam.
When the locking device is an unlocked position, shown in Figure 3, the rope may pass through the locking device.
The rope 20 has a first end 23, a middle portion 21 and a second end 22. A
clip 25 is attached to the first end 23 of the rope. The clip 25 is configured to connect to the middle portion 21 of the rope such that the clip 25 can slide along the middle portion 21 of the rope.
A first liandle 27 and a second handle 31 are attached to the iniddle portion 21 of the rope. The first handle lias a hand grasping niember 28 and a tube 29 that has a bore sized and configured to slidably receive the rope 20. Tube 29 permits a user to niove the tirst handle 27 along the middle portion 2I of the rope. The second hAndle 31 also has a grasping member 30 and a tube 32. Tube 32 has a bore that is sized and configured to slidably receive the rope 20 so a user can move the second liandle 31 along the niicldle porlion 21 of the rope, Tubes 29 and 32 tnay be coti7posed of plastic, leather, canvas or any combination thereof. I
prefer to attach aNvear pad 33 to cach tube, whicli presses against a pole being clirnbed.
When n user c[imbs a pole, the tiser places the first end 23 of the rope around the pole and attaches clip 25 to the middle portion of the rope such that the rope forms a loop around the pole.
As a user clin7bs up the pole, (he loop acts as a restraint to prevent the user fi-om falling from the pole. Wlien the usei reaches a particular position on the pole, the user may stop clinlbing to perform work at that position. When performing work on a pole, a user typically leans away froni the pole to ensure the loop is in a tight, frictional engagement with the pole so the user can easily maintain liis or her pasition on the pole.
Preferably, the first strap 17 and second strap 15 extenci to a position adjacent to and forward of the middle portion 6 of the belt 3 so that the position of the locking device 18 is forward to and adjacent to tlie niiddle of the belt. Such a position allows a user to easily see the locking device 18 so that the user can easily nianipulate the loclcing device 18 or verify that the locking device 18 is in a locked or an unlocked position.
Most preferably, the first connector 9 and the second connector 11 are equidistant from the buckle 19 and the first strap 17 and second 15 strap extend a substrlntially equal distance from tlieir respective connectors 9, 11 to position the locking device 18 adjacent to and forward of the front middle portion 6 of the he1t. Such positioning ensttres the stress frorn the rope and locking device is equally distribtited on botli sides of the belt so a user can work while maintaining a conlfortable position, such as the position illtistrated in Figure 5, when on a pole 36. Pole.36 may be a tree trtink, a utilit,y pole, or any other tall elongated body.
It sllould be appreciated that an equal distribution of force makes it easier ftor a user to maintain his or her balance and position on a pole and prevents the user from assuming an uncornfortable posture wliile performing work while on the pole. For example, the equal distribution of force to botli sides of the belt prevents a user from having to compensate fora dispropor-tionate aniount of stress that may be distributed along one of the two straps by leaning toward the other strap or taking some other corrective ac,tion to maintain a stable position while working on a pole.
The forward and central positioning of the locking device relative to the user also permits a user to eEisily see and operate the locking device without having to subsiantially move his or her body to see the loclcing device. A user working on a utility pole, for example, should only have to lower his or her head to observe the loclcing device to verify it is in the locked position or to see the locking device 18 when ad,justing the length of rope 20 e:ctending from a side of the locking clevice 18. Suclt a head movement is niuch simpler and requires nluch less movenlent than the rnovements required by the positioning of locking devices in other safety restraints, wlaich often require the user to twist his or her head to the right or left to see the locking device.
The position of the locking device 18 of device 1 is maintained in substantially the same location so that a user can easily find the device or deterrnine the location of the lor.king device.
Otller devices often have locking devices or rope corutecting mechanisms that are moveable along thc rope, belt, or harness so that a user must move his or her head in various, and sonietimes uncorrifortable, locations to see the locking device. Tlrc prc;dictable or kiiown position of ihe locking device 18 of'device I helps to greatly redtiee, if not eliminate, any concern the tiser may havc regarding the locked or unlocked status of'the locking device while working on a pole. For instance, a user should not have to rnalce any substantial movements to tind and observe the locking device 18 of device 1, which can alleviate, if not eliminate, some concerns a worker niay hnve about verifying the setting of the locking device.
I-landles 27 and .31 permit a user climbing a pole to climb at a quicker rate.
Further, the handle s permit a user to clinib up or down a pole rnore efficiently than other devices, For example, a user need not waste energy attempting to grab part of the loop that sun-ounds a pole while clinibing or descend'uig to readjust the position of the loop, whicli is often diftictilt and tinie consuming because of the loop's tight engagement with the pole and the srnall diameter of the rope. 7he liandles permit a user to easily readjust the position of the loop by grabbing the grasping members 2$, 30 of the respective handles to pull the loop upwards or downwards to"
reposition the loop. Of cotu-se, a user may only need to grab one of the grasping members to effectively reposition the loop, which rec3uires much less tiine and effort than attempting to grab a part of the loop. Moreover, the adjitstability of the handles allows a user to alter the position of the handles 27 or 31 to make repositioning the loop easier. For instance, tubes 29 and 32 permit a user to slide one or both handles along the middlc portion 21 of the rope away from or toward the first end 23 of the rape to place the handles in a desired position.
Wear pads 33 niay be attached to the tubes to increase the durability of the handlcs. The wear pads are preferably made of leather or canvas, but may be made ol'otlier materials as well.
As may best be appreciated in Figure 5, the wear pads are connected to the tubes so that the wear pads engage the pole being climbed by the user.
It should be undersfiood that the teeth 26 of the cam 24 of the locking device 18 can be configtired to permit the cope 20 to pass through the locking device 18 in a first direction when the locking device 18 is in the locked position, but prevent the rope from passing through the locking device in an opposite second direction. The first direction is preferably toward the first end 2.3 of`the rope so that the user does not have to manipulate the locking device to obtain additional slack for tlie loop as lre or she climbs tip a pole. For such enibodiments of my device, the second end 22 of the rope prefeiably has a large knot or stop that prevents the second end from passing through the locking device. Of course, other embodiments may llave a locking device that prevents the rope fi-om passing throtigh any part of the locking device when the locking device is in the locked position.
The handles 27 and 31 may be interconnected by an adjustable fotirth strap 34, as may best be seen in Pigure 2. It should be understood that other embodiments may liave only one handte adjustably connected to the rope 20. In yet other embodiments, one handle may be adjustably connected to the rope and one or more non-movable liandles may be affixed along the rope 20 stich that tlie position of the non-movable handies cannot be adjusted.
The device 1 illustrated in Figures 1-5 and other embodiments of my pole climbing and fall restraint device may be included in a ftill or partial body harness worn by a user climbing a pole oa, otlier tall elongated object. The device I and other embodiments may also be sold and worn separate frotn such liarnesses. Wlien par4 of a hamess, the belt 3 may be worn such that the belt is positioned at a user's waist, above a tiser's waist, or below a user's waist. For example, the belt 3 may be designed to be positioned on or below a user's buttocks wl-ien incorporated into a ftill body liarness.
Referling to Figures 6-7, a second present preferred embodinient 51 of my pole clinibing and fall resti-aint device is illustrAted. Embodiments of rny invention siniilar to the second present preferred embodiment 51 may be referred to as a lanyard apparatus. The lanyard apparatus inc.ludes a pole strap 52 that extends througlt a locking mechanism 58. The pole strap is sized and c.onrgured to arijustably wrap abotit a pole. The loclcing nseclianism 58 is attached to a coriilector 56. Preferably, the connector 56 is a triple lock carabiner.
The first end 53 of the pole strap 52 is attached to a coupling 55. A first liandle 91 a second handle 92 are moveably attached to the pole strap 52. 1 prefer that the handles 91 and 92 include hooks, such as J-hooks, so that a user can easily slip liis or her hand into the hook and keep the liook on the hand while climbing. Other configtirations, stich as a loop could also be used. A tirst stop 67 and a second stop 68 are also moveably attached to the pole strap 52.
The first handle 91 incfudes a Frst hook 62 and a strap 94 that attaches the Crst hook 62 to the pole strap 52. The connecting strap 94 extends from the pole strap 52 to the first Ilook 62.
The strap attaches the first hook 62 to the pole strap 52 sucli that the first hook 62 may be rotated about the pole strap 52 and rnay also be slid along the pole strap 52. A user may slide or rotate the first hook 62 independently or at the sarne time. 'The connecting strap 94 positions the first hook 62 a first distance away from the pole strap 52. Preferably, the frst distance is 8-13 inches.
Ihe second handle 92 includes the second ltook 63 and a strap 96 that atiaches the second hook 63 to the pole strap 53. The connecting strap 96 extends from the pole strap 52 to the second hook 63. The strap 96 connects the second hook 63 to the pole strap 52 such that the second hook 63 may be rotated about the pole strap 52 and may also be slid along the pole strap 52. The sliding and rotating of the second hook may be done independently or in combination.
The connectirrg strap 96 positions the second hook 63 a second distance away from the pole strap 52. Preferably, the second distance is 3-5 inches.
I have founci that liaving both hooks positioned at ditferent distances fronl the pole strap 52 helps a user readjust the pole stiap 52 as the user climbs a pole. Indeed, the hooks 62 and 63 allow a user to more easily move and readjust the pole strap 62 while climbing than handies 27 and 31, as may be appreciated from Figure 8. For example, it has been determined that a user climbing a pole can rnore easily manipulate the pole strap 52 with hooks because the hooks perrnit a tiser to manipulate the pole strap 52 without tightly holding the hooks. Preferably the liooks are cnnfigtired to open away from the pole or pole strap 52 when a user is lifting the hoolcs upward for climbing a pole. Such an orientation has been found to permit a user to easily place one or more fingers or the user's entire liand under the hooks to move the pole strap. Positioning the hooks away frorn thc pole strap 52 by the connecting straps also perniits a user to more easily find, move and grasp the liooks to adjust the position of the pole strap as the user clinibs a pole.
The first stop 67 is positioned between the first liook 62 and the second hook 63. The first stop 67 is configured to help stop movement of the first and second hooks 62 and 63 along the pole strap 52 to prevent the hooks from both being positioned next to each nther. Such a position has been found to help avoid situations where a user must readjust the position of one of the hooks or handles due to movement of both hooks to one side of a pole.
Positioning the first stop 67 between the first and second hooks 62 and 63 can also help prevent a user having to grab around the pole in an attenipt to find one of the hoolts that may lrave moved while the user worked or readjusted his position on a pole.
The second stop 68 is positioned along the middle portion of the pole strap 52. The second stop 68 is adjustable along the length of the pole strap and can be used as a stop or parking tap to he.lp prevent movenient of the coupling 55 while the coupling is attached to the iniddle portion of the pole strap 52. By preventing such movenient of the coupling 55, the second stop 68 can lielp prevent the pule strap 52 from becoming loosened in use so that a user stays wrapped about a pole he or she may be positioned cii and is prevented froni accidentally faliing while the use works on a pole or climbs up or down a pole.
In some cmbodiments the first stop 67 may include an engaging device 71 that is contigured to engage or pierce a pole or other structure that may be climbed.
An engaging device '71 can be particularly helpful in ensuring the pole strap 52 is properly engaging a pole that may be slick due to ice, snow or other relatively slick condition. The engaging device 71 may include a nail, screw, bolt, hook, a rough surface or at least one saw tooth. More than one engaging device 71 iuay be attached to the first stop 67. The cngaging device 71 may also be used to help attach the first stop 67 to the pole strap 52. For instance, a portion of the engaging device may be used to secure a connecting strap to the pole strap 52 while a second portion of the engaging device projects past the pole strap 52 such that the second porti.on of the engagement device can engage a pole.
In some embodiinents of the lanyard apparatus, the connector 56 or locking mechanism 58 may not be included. It is contemplated that such einbodiments of my lanyard apparatus will be configured for attachment to a pole climbing belt, or harness or otlier belt device. A
connector or locking mechanism configured for attaching the lanyard apparatus to the belt, harness or other belt device may be used to attach the lanyard apparatus to the belt hai-ness or other belt device. It is also contemplated that a belt, harness or other belt device can include such a connector or locking mechanism, The second embodiment 51 of my pole climbing and fall restraint device may also be provided in a kit. Such a kit may include a belt device that is similar in construction to the belt device illustrated in Figures 1 and 3-5. Sttch a belt device can include the belt 3, first, second and third connectors 9, 11 and 13, and first and second straps 15 aiid 17, as shown in the belt 3 of Figures t and 3-5. 7'he locking device may be provided with the belt device, the lanyard apparatus, or provided separtitely. The belt device, locking device and lanyard apparatus may be packaged together or packaged separately. Similarly, tbey may be sold together or sold scparately.
It should be understood that rope 20 or pole strap 52 may be a lanyard, a cable, a wire, or other elongated member. The rope 20 or pole strap 52 may be composed of elastomers, syntlretic fibers, nattiral fibers, leather, eanvfls or any combination thereof.
Of course, other varlarions of the present preferred embodiments discussed above may be m7de. For exaniple, embodiments of my pole climbing and fall restraint device can include no stops, only one stop, or more than two stops. As another example, one hook or more than two hooks or other liandles can be included in other embodiments of my pole climbing and fall restraint device.
While I have shown and described certain present prefen-ed embodiments of my pole elimbing and fall restraint device and pole climbing and firll restraint device kit and have iliustrated certain present preferred methods of making and using the same, it is to be distinctly understood that the invention is not Iirnited thereto but may be otherwise variotrsly embodied and practiced witiiin the scope of the following claims.
