    [001] The present application claims benefit pursuant to 35 U.S.C. § 119(e) of US provisional application serial number 61/445,773, filed February 23, 2001, which is hereby incorporated by reference in its entirety. field of invention
    [002] The present invention relates to a traction device or anchoring clip to secure a cable to a support through an insulating device. More particularly, the present invention relates to an anchor clamp assembly that receives cables of various sizes. Even more particularly, the present invention relates to a wedge anchor clamp assembly in which the claws are prevented from accidentally exiting a body of the clamp assembly. Background of the invention
    [003] Conventional closed ends secure electrical transmission lines to support structures such as towers or poles. Closed ends include a mechanism for gripping a cable or conductor so that traction in the line is distributed through the insulated support to the tower or pole. Conventional closed ends often include clamps compressed together by nuts and bolts, but their effectiveness decreases over time as overtightening of nuts and bolts can cause metal fatigue and eventually failure.
    [004] Some conventional closed ends include spring-loaded wedge-shaped grips for gripping cables or conductors. While this is an improvement over closed ends comprising clamps compressed together by nuts and bolts, spring loaded closed ends have problems with interlocking characteristics.
    [005] There is a need for an anchor clamp configured to secure a power cable or conductor to a power pole through an insulator device with a single-body gripper guide and a profiled locking mechanism to prevent the grippers from sliding into outside the claw guide. Invention Summary
    [006] Therefore, an object of the invention is to provide a wedge anchor clamp assembly having a single body with first and second claws and first and second claw guides and an interlock feature having at least one ball bearing received in each of the grip guides to lock the respective grips into the grip guides.
    [007] Another objective of the invention is to provide openings along the upper surface of the claw guides for mounting the ball bearings and receiving pins to secure the ball bearings in the claw guides.
    [008] A further object of the invention is to provide a wedge anchor clamp assembly having a fin along the outer surface of a claw to engage a corresponding groove along the inner surface of the corresponding claw guide.
    [009] Yet another object of the invention is to provide a wedge anchor clamp assembly having a recoil mechanism characterized by a fin disposed on its upper surface and a ball to improve user grip on the fin.
    [010] Yet another object of the invention is to provide a wedge anchor clamp assembly having a bending eye large enough to accommodate large ton industry hooks of various sizes.
    [011] Another objective of the invention is to provide a key-shaped fitting adjacent to one of the claw guides to receive a spring in it.
    [012] A further objective of the invention is to provide a supplementary opening along the upper surface of the second claw guide, offset from the first opening, to receive a pin adjacent to the spring to secure the tension spring.
    [013] The device can accommodate a wide range of cables because the first and second claws are angled towards the end of the clamp. The anchor clamp assembly includes an interlock feature to secure the claws to the front end of the clamp. By forming the wedge anchor clamp assembly in this way, the wedge anchor clamp assembly can be used to accommodate a wide range of cables attached to power poles while also providing a secure tool for the user with improved gripping characteristics. .
    [014] The above objectives are basically achieved by a clamp assembly having a body with a base and first and second claw guides extending outward from the base. A runner has first and second ends formed between the first and second gripper guides. The first and second claws are movably received in the chute to receive a cable therebetween. The first claw engages the first claw guide. The second claw engages the second claw guide. The first claw engages the second claw such that the first and second claws move together. A pin is disposed in the body near the first end of the chute. A spring has a first end connected to the pin and a second end connected to the second claw for pulling the first and second claws towards the first end of the chute.
    [015] As used in that application, the terms "front", "rear", "side" and other orientation descriptors are intended to facilitate the description of the wedge anchor clamp assembly, and are not intended to limit the structure of the wedge anchor clamp assembly. wedge anchorage to no specific orientation or position.

    [018] In all drawings, like reference numbers will be understood to refer to similar parts, components and structures. Detailed description of the invention
    [019] Turning to Figures 1-21b, a wedge anchor clamp assembly 10 includes a gripper body 12 with a base 13 of which first and second gripper guides 14 and 16 extend outwardly. The second claw guide 16 faces the first claw guide 14 and forms a rail 5 therebetween. First and second claws 20 and 24 for receiving a cable or conductor 1 therebetween are movably received by runner 5 of gripper body 12. First claw guide 14 defines a first entry slot 18 for receiving a first claw 20. The second claw guide 16 defines a second entry slit 22 for receiving a second claw 24. The claws 20 and 24 are movable between the rear end 30 of the gripper body 12 and the front end 32 of the gripper body 12. Specifically, the first claw 20 slides from a rear end 26 of the first claw guide 14 to a front end 28 of the first claw guide as the second claw 24 substantially simultaneously slides from a rear end 34 of the second claw guide 16 to a front end 36 of the second claw guide 16.
    [020] The width of a rear end 30 of the chute 5 is greater than a width of a front end 32 of the chute 5, as shown in figures 1-3, and is substantially V-shaped. the inner surfaces 6 and 7 of the claw guides 14 and 16 are angled inwardly from the rear end 26 to the front end 28 to cause the first and second claws 20 and 24 to move together as the first and second claws move through the trough. 5 towards a rear end 30 thereof and away from each other as the claws 20 and 24 move towards the front end 32. The first entry slit 18 is formed in the inner surface 6 of the first claw guide 14, and the second entry slit 22 is formed in the inner surface 7 of the second gripper guide 16. The first and second entry slits 18 and 22 extend from the rear end 30 to the front end 32 of the gripper body 12, as shown in figure 1 .
    [021] Each of the first and second jaws 20 and 24 include a longitudinally extending fin 38 and 40, respectively, protruding from the main central portion of each jaw body and received in respective inlet slots 18 and 22. cup 38 and 48 includes at least one circular fin opening 44 and 54, respectively, for receiving a ball bearing (described in further detail below) with respect to the interlock feature. The first and second claws 20 and 24 also include a plurality of teeth 37 and 46, respectively, along the surfaces of the first and second claws 20 and 24 that face the interior of the gripper body 12. The teeth 37 and 46 are used. to grasp the cable 1 received between them. As the first and second claws 20 and 24 move from the rear end 30 of the gripper body 12 towards the front end 32, the first and second claws 20 and 24 move laterally towards each other, and the teeth 37 and 46 engage the cable 1 and increase the grip between them.
    [022] The second claw guide 16 includes a key-shaped opening 52 adjacent to the second input slot 22, as shown in Figures 1, 9 and 10. The dished portion 52a of the opening 52 of the second input slot 22 receives a spring 50 is actuated adjacent to second claw 24 to pull claws 20 and 24 toward front end 32 of gripper body 12 when the claws are coupled by a connecting mechanism 11. Spring 50 has a first end 51 secured to a pin 43 received. through an opening 41 in the second claw guide 16. A second and opposite end 53 of the spring 50 is secured to a side projection, or hook 91 extending outwardly from a fin 38 of the second claw 24. The claws 20 and 24 are slidably and releasably connected together as described below. Spring 50 is preferably actuated on one side of gripper body 12, such as the side adjacent to second claw guide 16 as shown in Figure 1, and biases both first and second claws 20 and 24 forward when first claw 20 and second claw 24 are connected.
    [023] The first claw 20, as shown in Figures 12 - 16 includes a recoil mechanism 60 disposed on its upper surface. The recoil mechanism 60 includes a claw opening 62 for a user's finger and a ball 64 disposed adjacent to the claw opening 62. Preferably, a portion of the ball 64 is disposed above the claw opening 62. The ball 64 increases grip. a user to facilitate retracting the first claw 20 and pulling the first claw towards the rear end 30 of the gripper body 12.
    [024] The first fin 38 extends outwardly from an outer surface 47 of the first claw 20, as shown in figures 12 - 14a, 15 and 16, from a rear end 49 to a front end 55 of the first claw 20 At least one opening 44 is formed in the first fin 38 to receive a ball bearing when the first fin 38 is received by the first inlet slot 18 in the first claw guide 14. As shown in Figure 14a, the outer surface 47 is sloped. inward from the rear end 49 to the front end 55 of the first claw 20, thereby facilitating movement of the first claw 20 through the rail 5 of the gripper body 12. The outer surface 47 of the first claw 20 has an angle substantially equivalent to that of the inner surface 7 of the second claw 16. A handle receiving groove 57 is formed in an inner surface 56 of the first claw 20 to receive the handle 1. Preferably, a plurality of teeth 36 is formed. riveted in the handle receiving groove 57 to facilitate gripping of the handle 1. A tongue 58 extends outwardly from the inner surface 57 to engage the second claw 24 such that movement of the second claw 24 results in movement of the first claw 20 .
    [025] The second fin 48 extends outwardly from an outer surface 59 of the second claw 24, as shown in figures 14b and 17 - 21b, from a rear end 63 to a front end 65 of the second claw 24. At least one opening 54 is formed in the second fin 48 to receive a ball bearing when the second fin 48 is received by the second entry slot 22 in the second claw guide 16. As shown in Figure 21a, the outer surface 59 is inclined inwardly. from the rear end 63 to the front end 65 of the second claw 24, thereby facilitating movement of the second claw 24 through the runner 5 of the gripper body 12. The outer surface 59 of the second claw 24 has an angle substantially equivalent to that of the inner surface. 6 of the first claw 14. A handle receiving groove 66 is formed in an inner surface 67 of the second claw 24 for receiving the handle 1. A recess 69 is formed in the second claw 24, as shown in the figures. 21a and 21b, which receives the tongue 58 of the first claw 20. A hook 91 extends outwardly from the second fin 48 and receives a second end 53 of a spring 50.
    [026] The tongue 58 of the first claw 20 and the recess 69 of the second claw 24 form a connecting mechanism for releasably and slidably connecting the first and second claws together. The connection mechanism is similar to the connection mechanism described in US patent number 6,547,481 to Grabenstetter et al., the subject matter of which patent is hereby incorporated by reference in its entirety.
    [027] The gripper body 12 includes an interlock feature to prevent the first and second grippers 20 and 24 from sliding all the way out of gripper guides 14 and 16. More specifically, each gripper guide 14 and 16 includes at least one gripper guide opening 40 and 71, respectively, along its upper surface for receiving a ball bearing 42 and 73. Preferably, the ball bearings 42 and 73 are dropped into the openings 40 and 71 of the respective claw guides 14 and 16 and received in the circular fin openings 44 along a track of the first and second jaws 20 and 24. As the first and second jaws 20 and 24 move in the trough 5 to grip a cable 1, the ball bearings 42 are inserted through. of the ball bearing insert openings 40 along the jaw guides 14 and 16 and received in the fin openings 44 along the fins 38 of the first and second jaws 20 and 24.
    [028] Slots 18 and 22 of grip guides 14 and 16 have slightly curved longitudinally extending top and bottom surfaces 83 and 84 to accommodate and slidably receive ball bearings 42 which extend beyond and are retained in fin openings 44 and 54 of the first and second jaws 20 and 24. As the first and second jaws 20 and 24 slide on the jaw guides 14 and 16, the curved surfaces 83 and 84 have locking elements 81 and 82, as shown in Figures 5 , 6 and 10, adjacent to the rear end 30 to engage the ball bearings 42 and 73 to limit withdrawal of the first and second jaws 20 and 24 from the rear end 30. As shown in Figure 10A, the locking elements 81 and 82 may be an inwardly extending wall to reduce the diameter of the curved surfaces 83 and 84 to prevent the ball bearings 42 and 73 from passing through the rear end 26 of the grip guides 14 and 16.
    [029] After the first and second jaws 20 and 24 are pushed towards the front end of the gripper body 12, pins 39 and 75 are inserted through openings 40 and 71 along the jaw guides 14 and 16 to further secure the bearings of balls 42 in the jaw guides 14 and 16. The second jaw guide 16 includes a spring opening 41 for receiving a spring pin 43. The spring opening 41 is offset from the openings 40 for the ball bearings 42. Spring opening 41 is received in key-shaped opening 42 of second claw guide 16 to secure spring 50 thereto.
    [030] The wedge anchor clip 10 also includes a leg 68 connecting the main body 12 to the rear 70 of the wedge anchor clip 10.

A cotter pin 77 is received through a cotter pin opening 79 disposed in the screw 78 to secure the screw 78 through the first and second openings 74 and 76.
    [031] The wedge anchor clamp 10 further includes a bending eye 80 under the gripper body 12. The bending eye 80 is a loading tool used to relieve tension in the electrical transmission line while the cable 1 is installed between the claws 20 and 24. Preferably, the bending eye 80 extends substantially perpendicularly from the gripper body 12.
    [032] Preferably, the gripper body 12 and the first and second grippers 20 and 24 are unitarily formed as a single piece and made of an aluminum alloy. Spring 250 is preferably made of stainless steel. Assembly and operation
    [033] The wedge anchor clamp assembly 10 is shown prior to engaging a cable in Figure 1. The first claw 20 is disposed on the rail 5 of the gripper body 12 such that the first fin 38 enters the first entry slot 18 of the first claw guide 14. The second claw 24 is disposed on the runner 5 of the gripper body 12 such that the second fin 48 enters the second entry slit 22 of the second claw guide 16. The second end 53 of the spring 50 is attached to hook 91 of the second claw, as shown in figure 1.
    [034] The first jaw 20 is moved through the chute 5 such that the first opening 44 in the fin 38 is aligned with the opening 40 in the first jaw guide 14. A first ball bearing 42 is then dropped through the opening. 40 such that it is received by opening 44 in first claw 20. As shown in Figure 16, first claw 20 has two openings 44 such that first claw 20 is moved forward through chute 5 towards the front end. 32 until the next opening 44 is aligned with the opening 40 in the first claw guide 14. A second ball bearing 42 is then dropped through the opening 40 such that it is received by the opening 44 in the fin 38 of the first claw 20. The pin 39 is then disposed in the opening 40 in the first claw guide 14 to prevent the ball bearings from passing out through the opening 40. The first claw 20 is shown having two openings 44 in the first fin 38, but any n. appropriate number of openings can be used. The ball bearings 42 travel in the curved portion 83 of the first inlet slot 18, thereby facilitating movement of the first jaw 20 through the chute 5. The plug 81 near the rear end 30 of the chute 5 prevents the first jaw 20 from coming out. accidentally from the rear end of the first inlet slot 18. As shown in Fig. 10A, the plug 81 is an inwardly extending wall that reduces the diameter of the curved portion 83 to prevent the ball bearing 42, which has a larger diameter. , exit inlet slot 18.
    [035] The second jaw 24 is moved through the chute 5 such that the first opening 54 in the fin 48 is aligned with the opening 71 in the second jaw guide 16. A first ball bearing 73 is then dropped through the opening 71 such that it is received by the opening 54 in the second claw 24. As shown in Figure 18, the second claw 24 has two openings 54 such that the second claw 24 is moved forward through the runner 5 towards the front end. 32 until the next opening 54 is aligned with opening 71 in second jaw guide 16. A second ball bearing 73 is then dropped through opening 71 such that it is received by opening 54 in fin 48 of second jaw 20 The pin 75 is then disposed in the opening 71 to prevent the ball bearings 73 from passing out through the opening 71. The second jaw 24 is shown having two openings 54 in the second fin 48, however any suitable number of openings can be used. The ball bearings 73 travel in the curved portion 84 of the second inlet slot 22, thereby facilitating movement of the second jaw 24 through the chute 5. The plug 82 near the rear end 30 of the chute 5 prevents the second jaw 24 from accidentally coming out of the the rear end of the second inlet slot 22. As shown in Figure 10A, the plug 82 is an inwardly extending wall that reduces the diameter of the curved portion 84 to prevent the ball bearing 73, which has a larger diameter, from coming out of the slot. input 22.
    [036] The second claw 24 is moved forward through the slit until the first end 51 of the spring 50 is aligned with the opening 41 in the second claw guide 16. The spring pin 43 is inserted into the opening 41 such that it engages the hook at the first end 51 of the spring 50, which is secured at the first end 51 to the pin 43 and at the second end 53 of the hook 91 of the second claw 24. Preferably, the spring 50 is a tension spring for pulling the first and second claws 20 and 24 towards the front end 32 of gripper body 12.
    [037] The cable 1 is disposed in the track 5 of the gripper body 12 between the first and second claws 20 and 24, as shown in figures 2 and 3. The cable 1 is received by the cable engaging grooves 57 and 66 of the first and second claws 20 and 24. The handle receiving grooves 57 and 66 preferably have a plurality of teeth 37 and 46 to facilitate gripping of the handle 1. The tongue 58 of the first claw 20 engages the recess 69 in the second claw 24 such that the first claws. and second claws 20 and 24 move together.
    [038] An electrician can then use a hook pole to engage the bending eye 80 to pull the wedge anchor clamp assembly 10 in a backward direction (toward the yoke 72). This movement causes the first and second claws 20 and 24 to move towards the front end 32 of the runner 5 of the gripping body, such that the first and second claws also move laterally together due to the decreasing angle of the first and second claw guides 14 and 16, as shown in figure 3. The movement of the first and second claw guides 20 and 24 towards the front end 32 of the runner 5 is stopped when the width of the runner 5 between the first and second claw guides 14 and 16 is substantially equal to the width of the first and second claw elements 20 and 24 and the handle 1 as shown in Figure 3. Therefore, a tight and secure grip between the claws 20 and 24 and the handle 1 is created. .
    [039] The wedge anchor clamp assembly 10 is then connected to a bracket, such as an insulator. Engagement yoke pin 78 is passed through openings 74 and 76 in the yoke to secure clamp assembly 10 to the bracket. A cotter pin 77 is passed through the hitch pin 78 to prevent accidental removal of the hitch pin 78 from the openings 74 and 76.
    [040] To disengage cable 1 from grippers 20 and 24, a user may pull back on recoil mechanism 60, thereby moving grippers 20 and 24 to the rear end 30 of track 5 to loosen grip on the cable. 1. Ball 64 and claw opening 62 of first claw 20 facilitate pulling claws 20 and 24 back such that clamp assembly 10 can be disengaged from handle 1.
    [041] The above modalities and advantages are merely exemplary and should not be construed as limiting the scope of the present invention. The description of exemplary embodiments of the present invention is intended to be illustrative and not to limit the scope of the present invention. Various modifications, alternatives and variations will be apparent to those of ordinary skill in the art, and are intended to fall within the scope of the invention as defined in the appended claims and their equivalents.
