The latch is releasably coupled to the first cleat set and the second cleat set and secures the weightlifting handle when the clip is in a closed state and releases the weightlifting handle when the clip is in an open state.

Description

Technical Field

[0001] The present disclosure generally relates to adjustable weight assemblies, fixtures therefor, and methods of using such adjustable weight assemblies. Background Art

[0002] Weightlifting handlebar clamps are commonly used to secure weights, such as metal or plastic weight plates, to the handlebars. The desired weights are placed on either end of the handlebars. The clamps are then slid onto either end of the handlebars. Once each handlebar clamp is placed against the weight plate, both clamps are secured in place. The clamps prevent the weight plates from sliding off the handlebars as the user completes various exercises.

[0003] Adjustable weight devices are used for various strength training exercises. Adjustable weight devices allow a user to use a single handlebar (e.g., a dumbbell handlebar) with multiple weight options. Adjustable weight devices also save space. A user can have multiple weight options, such as multiple dumbbell weight options, without having the space to store multiple full dumbbells. However, current adjustable weight devices are designed to be used with a single handlebar. Therefore, a user can only perform exercises with a single handlebar that is compatible with the adjustable weight device.

[0004] It would be advantageous to provide an alternative clamp for use with a variety of weight lifting handles, thereby providing an improved device that addresses one or more of the problems discussed above. Summary of the invention

[0005] One embodiment of the present disclosure is directed to a method of interchanging a weightlifting handle on an adjustable weight assembly. The method includes opening a first clamp on a first end of the adjustable weight assembly to disengage the first end of the weightlifting handle, and opening a second clamp on a second end of the adjustable weight assembly to disengage the second end of the weightlifting handle. The method also includes removing the weightlifting handle from the first clamp and the second clamp. The method also includes inserting another weightlifting handle into the first clamp and the second clamp, closing the first clamp on the first end of the adjustable weight assembly to engage the first end of the other weightlifting handle, and closing the second clamp on the second end of the adjustable weight assembly to engage the second end of the other weightlifting handle.

[0006] Another embodiment relates to a clamp for a barbell, comprising a first clamp set. The first clamp set comprises a first front clamp. The first front clamp comprises a first pivot point located on a first horizontal plane, a first slot located on a second horizontal plane above the first pivot point, a first lock opening located on an outer edge of the first front clamp and above the first slot, and a first clamp located on an inner edge of the first front clamp and between the first pivot point and the first slot. The first front clamp comprises a first protrusion located below the first clamp. The clamp also comprises a second front clamp opposite to the first front clamp. The second front clamp comprises a second pivot point located on the first horizontal plane opposite to the first pivot point, a second slot located on a second horizontal plane opposite to the first slot, and a second lock opening located above the second slot and opposite to the first lock opening. The clamp also comprises a lock.

The connecting plate 122 may be located at the center of the center rod 112. The plurality of bolts 124 are located on one side of the connecting plate 122. According to some embodiments, the center rod 112 may include a first rod 112a and a second rod 112b coupled by the connecting plate 122. For example, the connecting plate 122 and the plurality of bolts 124 may fix the first rod 112a to the second rod 112b.

[0035] The storage rack 108 may also include a first set of barbell seats (not shown) and a second set of barbell seats (not shown). The first set of barbell seats may be located on a first end of each of the first counterweight rack 110 and the second counterweight rack 114. The second set of barbell seats may be located on a second end of each of the first counterweight rack 110 and the second counterweight rack 114 that is opposite to the first set of barbell seats. The first set of barbell seats is configured to receive the first weightlifting handle 104. For example, the first set of barbell seats may receive and store the straight bar weightlifting handle 104a. The second set of barbell seats is configured to receive the second weightlifting handle 104. For example, the second set of barbell seats may receive and store the curved bar weightlifting handle 104b. The first set of barbell seats and the second set of barbell seats are configured to engage (e.g., receive, etc.) the first weightlifting handle 104a and the second weightlifting handle 104b, respectively, so that the optional clamp system 100 can be stored on and / or in the storage rack 108.

The second distal shell end 127b is opposite to the optional clamp 102. The second proximal counterweight shell end is located near the optional clamp 102. The second counterweight coupling portion 129b is located between the second distal shell end 127b and the second proximal shell end 128b and connects the two. The second counterweight shell 126 is configured to connect or release the counterweight of the desired weight in the second counterweight group 118 to the weight lifting handle 104.

[0038] The optional clamp for the weight lifting handlebar system 100 also includes a first weight dial 130, a second weight dial 132, a first weight button 134, and a second weight button 136. The first weight dial 130 is located on the first distal housing end 127a. The second weight dial 132 is located on the second distal housing end 127b. The first weight button 134 is located on the proximal end of the first weight shell 125. The second weight button 136 is located on the proximal end of the second weight shell 126. The first weight dial 130 and the second weight dial 132 rotate (e.g., clockwise, counterclockwise, etc.). For example, a user can press the first weight button 134 and rotate the first weight dial 130 in a first direction (e.g., clockwise) to increase the selected weight. The user can also press the first weight button 134 and rotate the first weight dial 130 in a second direction (e.g., counterclockwise) to decrease the selected weight. When the user releases the first weight button 134, the selected weight will be coupled to the weight handle 104. To maintain balanced weights on each end of the weight handle 104, the user can repeat the process, selecting the weights of the second weight set 118 using the second weight button 136 and the second weight dial 132.

[0039] The first weight group 116 and the second weight group 118 may include a first weight display 138 and a second weight display 140, respectively. The first weight display 138 may be located at a proximal end of the first weight group 116, adjacent to the first weight button 134. The first weight display 138 is configured to display a number associated with a selected weight of the first weight group 116. For example, when a user rotates the first weight dial 130, the first weight display 138 displays a number associated with the total weight on the first end of the weight lifting handle 104. The second weight display 140 may be located at a proximal end of the second weight group 118, adjacent to the second weight button 136. The second weight display 140 is configured to display a number associated with a selected weight of the second weight group 118. For example, when a user rotates the second weight dial 132, the second weight display 140 displays a number associated with the total weight on the second end of the weight lifting handle 104.

[0040] The clamp for the weightlifting handle system 100 also includes an optional clamp 102. The weightlifting handle system 100 includes at least one optional clamp 102. For example, an optional clamp 102 is located near the first weight group 116, and another optional clamp 102 is located near the second weight group 118. The optional clamp 102 is configured to selectively couple the weightlifting handle 104 to at least one of the first weight group 116 and the second weight group 118.

[0041] like Figure 3 As shown, the optional clamp 100 for a weightlifting handlebar system includes a front clamp cover 302. The front clamp cover 302 includes an opening 304. The opening 304 of the front clamp cover 302 can be generally U-shaped so that the weightlifting handlebar 104 can be placed in the optional clamp 102 (e.g., engaged, wrapped around, etc.). The front clamp cover 302 is coupled to the front side of the optional clamp 102. The front clamp cover 302 is configured to prevent objects from being stuck in the optional clamp 102. In addition, the front clamp cover 302 is configured to enclose the front and sides of the optional clamp 102.

[0042] More specifically refer to Figure 4 and Figure 5 , an exemplary embodiment of an alternative clamp 102 for use with the clamp system 100 is shown. The alternative clamp 102 includes a first clamp set 402 and a second clamp set 404. The first clamp set 402 and the second clamp set 404 define an expandable opening 406. The expandable opening 406 is located between the first clamp set 402 and the second clamp set 404. The expandable opening 406 is configured to receive a weightlifting handle 104. The first clamp set 402 and the second clamp set 404 are configured to engage the weightlifting handle 104 in the expandable opening 406 when the alternative clamp 102 is in a closed state, and release the weightlifting handle 104 when the alternative clamp 102 is in an open state.

[0043] The optional clamp 102 also includes a latch 408. The latch 408 is releasably coupled (e.g., selectively coupled, etc.) to the first clamp set 402 and the second clamp set 404. The latch 408 is configured to secure the first clamp set 402 and the second clamp set 404 to the weightlifting handle 104 when the optional clamp 102 is in a closed state. The latch 408 is also configured to release the first clamp set 402 and the second clamp set 404 from the weightlifting handle 104 when the clamp is in an open state. For example, when the optional clamp 102 is in an open state (e.g., the latch is released, disengaged, etc.), the expandable opening is larger (e.g., wider, etc.) than when the optional clamp 102 is in a closed state. For example, when the optional clamp 102 is in an open state, the first clamp set 402 and the second clamp set 404 are disengaged from the weightlifting handle 104, expanding the expandable opening 406 to allow the weightlifting handle 104 to be removed from the optional clamp 102.

[0044] The first clamping plate set 402 includes a first front clamping plate 410. The first front clamping plate 410 includes a first pivot point 412 and a first slot 414. When the optional clamp 102 is moved along the longitudinal axis (eg, the center axis A) C ) is located on the lower half of the first front clamp plate 410. The first pivot point 412 can be a circular opening configured to receive one of the plurality of screws 416. When the optional clamp 102 is rotated along a longitudinal axis (e.g., the central axis A C ), the first slot 414 is located above the first pivot point 412 and in the upper half of the first front clamping plate 410. The first slot 414 can be generally oval and configured to receive one of the plurality of screws 416. For example, the first slot 414 is configured to allow the screw 416 to move laterally within the first slot 414, thereby allowing the first front clamping plate 410 to pivot (e.g., rotate) outwardly about the first pivot point 412 to move relative to the central axis A. C The expandable opening 406 is enlarged.

[0045] The first front clamp plate 410 includes a first latch opening 418. The first latch opening 418 is located at an outer edge of the first clamp plate set 402 and above the first slot 414. For example, the first latch opening 418 is defined by the first clamp plate set 402. For example, the first front clamp plate 410 may include a first front clamp plate hook 411. The first front clamp plate hook 411 may define the first latch opening 418 and be configured to engage with the latch 408 to couple the first clamp plate set 402 with the second clamp plate set 404.

[0046] The first front clamp 410 also includes a first clamp 420. The first clamp 420 is located at the inner edge of the first clamp set 402 and between the first pivot point 412 and the first slot 414. The first clamp 420 defines a portion of the expandable opening 406. When the optional clamp 102 is in the closed state, the first clamp 420 contacts the weightlifting handle 104.

[0047] The first front clamp 410 also includes a first protrusion 422. The first protrusion 422 is located below the first clamp 420. The first protrusion 422 is configured to engage with the weight lifting handle 104. When the optional clamp 102 is in the open state, the first protrusion 422 can be in a first position. For example, when the clamp is in the open state, the first protrusion 422 can protrude upward into the expandable opening 406. When the weight lifting handle 104 is placed in the expandable opening 406, the first protrusion 422 can be in a second position. For example, when the first front clamp 410 pivots (e.g., rotates, moves, etc.) about the first pivot point 412 to the closed position, the first protrusion 422 can move downward.

[0048] The second clamping plate set 404 includes a second front clamping plate 424. The second front clamping plate 424 is opposite to the first front clamping plate 410. The second front clamping plate 424 includes a second pivot point 426 and a second slot 428. When viewed along the longitudinal axis of the optional clamp 102, the second pivot point 426 is located on the lower half of the second front clamping plate 424 and is opposite to the first pivot point 412. For example, the second pivot point 426 and the first pivot point 412 can be along the first transverse axis A. T1 The second pivot point 426 may be a circular opening configured to receive one of the plurality of screws 416. When the optional clamp 102 is positioned along its longitudinal axis (eg, the central axis A C ) When viewed from above, the second slot 428 is located above the second pivot point 426 and in the upper half of the second front clamping plate 424, and is opposite to the first slot 414. For example, the second slot 428 and the first slot 414 can be along the second transverse axis A. T2 position.

[0049] The second clamp set 404 also includes a second clamp 430. The second clamp 430 is located at the inner edge of the second clamp set 404 and between the second pivot point 426 and the second slot 428. The second clamp 430 is also opposite the first clamp 420. The second clamp 430 defines a portion of the expandable opening 406. When the optional clamp 102 is in the closed state, the second clamp 430 contacts the weightlifting handle 104.

[0050] The second front clamp plate 424 includes (e.g., defines) a second latch opening 432. The second latch opening 432 is located on the outer edge of the second clamp plate set 404 and above the second slot 428. The second latch opening 432 selectively connects the second clamp plate set 404 to the first clamp plate set 402. For example, the second latch opening 432 can be defined by a hook or hole configured to engage with the latch 408. For example, the second front clamp plate 424 can include a hole 434 that defines the second latch opening 432.

[0051] like Figure 4 As shown, the optional clamp 102 also includes a back plate 436. The back plate is located behind the first clamp set 402 and the second clamp set 404 and adjacent to the proximal housing end 128. The back plate 436 is located a distance from the first clamp set 402 and the second clamp set 404. The back plate 436 is configured to couple the optional clamp 102 to the proximal housing end 128. The first clamp set 402 and the second clamp set 404 and the back plate 436 define a cavity for receiving the end of the weightlifting handle 104.

[0052] like Figure 5 As shown, the first clamp set 402 also includes a first rear clamp 502. The first rear clamp 502 includes a first rear pivot point 504 and a first rear slot 506. When viewed along the longitudinal axis of the optional clamp 102, the first rear pivot point 504 is located at the lower half of the first rear clamp 502. The first rear pivot point 504 can be a circular opening that is configured to receive one of the plurality of screws 416. The first rear pivot point 504 is axially aligned with the first pivot point 412.

[0053] When viewed along the longitudinal axis of the optional clamp 102, the first rear slot 506 is located above the first rear pivot point 504 and in the upper half of the first rear clamp 502. The first rear slot 506 is aligned with the first slot 414. The first rear slot 506 can be generally oval and configured to receive one of the plurality of screws 416. For example, the first rear slot 506 is configured to allow the screw 416 to move laterally within the first rear slot 506. For example, the first rear clamp 502 is configured to pivot (e.g., rotate) outwardly about the first rear pivot point 504 to move relative to the central axis A. C The expandable opening 406 is enlarged.

[0054] The first rear cleat 502 also includes a first rear cleat hook 507. The first rear cleat hook 507 is located at the top edge of the first rear cleat 502. In other embodiments, the first rear cleat hook 507 can be located on the side or bottom of the first rear cleat 502. The first rear cleat hook 507 is aligned with the first front cleat hook 411. For example, the first rear cleat hook 507 is opposite to the first front cleat hook 411 and is aligned with the first front cleat hook 411. The first front cleat hook 411 and the first rear cleat hook 507 can together define the first locking opening 418. In contrast, in other embodiments, the first front cleat hook 411 and the first rear cleat hook 507 can be holes (e.g., circular openings, grooves, etc.) that define the first locking opening 418.

[0055] The second clamping plate set 404 also includes a second rear clamping plate 508. The second rear clamping plate 508 includes a second rear pivot point 510 and a second rear slot 512. When viewed along the longitudinal axis of the clamping plate, the second rear pivot point 510 is located at the lower half of the second rear clamping plate 508. The second rear pivot point can be a circular opening configured to receive one of the plurality of screws 416. The second rear pivot point 510 is axially aligned with the second pivot point 426.

[0056] When viewed along the longitudinal axis of the optional clamp 102, the second rear slot 512 is located above the second rear pivot point 510 and in the upper half of the second rear clamp 508. The second rear slot 512 can be generally oval and configured to allow the screw 416 to move laterally within the second rear slot 512. For example, the second rear clamp 508 is configured to pivot outwardly about the second rear pivot point 510 to move relative to the central axis A. C The expandable opening 406 is enlarged.

[0057] The second rear clamping plate 508 also includes a second protrusion 516. The second protrusion 516 is located below the second clamp 514. The second protrusion 516 may be hook-shaped. The second protrusion may also extend across the central axis A of the optional clamp 102. C , so that the second protrusion 516 can overlap a portion of the first protrusion 422. The second protrusion 516 can move downward from a first position protruding into the expandable opening 406 to a second position flush with the first protrusion 422. For example, when the weightlifting handle 104 is placed into the expandable opening 406, the weightlifting handle 104 engages (e.g., contacts) each of the first protrusion 422 and the second protrusion 516, forcing the first front clamp 310 and the second rear clamp 508 to pivot about the second rear pivot point 510, thereby positioning the optional clamp 102 in the closed state. For example, the weightlifting handle 104 applies downward pressure on the first protrusion 422 and the second protrusion 516, respectively, causing the first front clamp 310 and the second rear clamp 508 to pivot about the second rear pivot point 510.

[0058] Once both the first cleat set 402 and the second cleat set 404 are in the closed position, the latch 408 may couple the first cleat set 402 to the second cleat set 404. The latch 408 releasably couples the first cleat set 402 and the second cleat set 404. For example, when the optional clamp 102 is in the closed state, the latch 408 couples the first cleat set 402 to the second cleat set 404. When the optional clamp 102 is in the open state, the latch 408 may couple to at least one of the first cleat set 402 and the second cleat set 404.

[0059] In general, as shown, the lock 408 is fixedly coupled to the second clamp set 404. For example, the second front clamp 424 and the second rear clamp 508 may include a lock hole (e.g., a second lock opening 432) located at the top edge of each of the second front clamp 424 and the second rear clamp 508 when viewed along the longitudinal axis of the optional clamp 102. In other embodiments, the lock 408 is removably coupled to each of the first clamp set 402 and the second clamp set 404.

[0060] The lock 408 may also include a front edge 522 and a rear edge 524. The front edge 522 is located inward (e.g., near the center of the optional barbell clamp system 100) from the rear edge 524 when viewed along the longitudinal axis of the optional clamp 102. For example, the rear edge 524 is located near the proximal housing end 128. A metal pin (e.g., a pin, a bolt, etc.) extends from the front edge 522 to the rear edge 524. The metal pin may be positioned through the lock hole of each of the second front clamp plate 424 and the second rear clamp plate 508.

[0061] The latch 408 includes a first portion 526 and a second portion 528. However, in other embodiments, the latch 408 may include only the first portion 526. The first portion 526 is configured to engage the first latch opening 418 and the second latch opening 432. For example, the latch 408 may include a first pin 530. The first pin 530 is configured to engage the first latch opening 418 of the first cleat set 402. For example, the first pin 530 may be disposed in the first latch opening 418 of the first cleat set 402 to secure the first cleat set 402 to the second cleat set 404, thereby closing the expandable opening 406 around the weightlifting handle 104. The first pin 530 may then be removed from the first latch opening 418 of the first cleat set 402 to release the latch 408, thereby opening the expandable opening 406 so that the weightlifting handle 104 may be removed from the optional clamp 102.

[0062] The lock 408 may also include a second pin 532. The second pin 532 is configured to engage with the second lock opening 432. For example, the second pin 532 may selectively engage with the second clamping plate set 404 via the second lock opening 432, such that the second pin 532 may be removed from the second lock opening 432. In other embodiments, the second pin 532 may be fixedly coupled (e.g., connected, fixed, etc.) to the second clamping plate set 404 within the second lock opening 432.

[0063] The second portion 534 is located at the distal end of the buckle 408. The second portion 534 is configured to secure and release the buckle 408 with the first and second cleat groups 402, 404. The second portion 534 includes a reduced end 536 and a connecting end 538. The reduced end 536 may have an ergonomic shape to help a user secure and release the optional clamp 102. The connecting end 538 is configured to couple the first portion 526 of the buckle 408 to the second portion 534. For example, the connecting end 538 may be inserted into the interior cavity of the first portion 526. Then, the second pin 532 may be placed through the first portion 526 and the second portion 534, thereby coupling the second portion 534 of the buckle 408 to the first portion 526.

[0064] The lock 408 also includes a release rod 540 and a third pin 542. The release rod 540 passes through the interior cavity of the second portion 534. The release rod 540 is also coupled to the second portion 534. The third pin 542 passes through the second portion 534 and the release rod 540. The third pin 542 is configured to couple the release rod 540 to the second portion 534. The release rod 540 is configured to prevent the lock 408 from releasing and opening the expandable opening 406 when exercising with the weight lifting handle. For example, the release rod can further secure the lock 408 and the optional clamp 102 in a closed state.

[0065] The release lever 540 includes a release piece 544 and a release hook 546. The release piece 544 is located at a portion of the release lever 540 and above the second portion 534. The release hook 546 is located at a portion of the release lever 540 and below the second portion 534. The release piece 544 is configured to release or disengage the release lever 540 from the second clamping plate group 404. The release hook 546 is configured to engage (e.g., contact, etc.) the second clamping plate group 404 to prevent the lock 408 from releasing and opening the optional clamp 102 at an unexpected time. For example, a user can press the release piece 544 to rotate the release lever 540 around the third pin 542 to disengage the release lever 540 from the second clamping plate group 404. By rotating the release lever 540 around the third pin 542, the release hook 546 also rotates. For example, when the release hook 546 rotates, the release hook is disengaged from the second clamping plate group 404. In contrast, in other embodiments, the lock 408 may include a release button instead of the release lever 540. For example, a user may press a release button to disengage buckle 408 from at least one of first cleat set 402 and second cleat set 404 .

[0066] Figures 6A to 6C An optional clamp 102 for use with the weightlifting handlebar system 100 is shown. Fig. 6A The optional clamp 102 is shown in a closed and locked state. Fig. 6A As shown, the optional clamp 102 may include a front plate 600. The front plate 600 is located in front of (e.g., opposite to, adjacent to, etc.) the first front clamp plate 410 and the second front clamp plate 424. The front plate 600 includes a plurality of front plate annular openings 601. The front plate annular openings 601 are configured to receive a plurality of screws 416 that couple the front plate 600 to each of the first clamp plate group 402, the second clamp plate group 404, and the back plate 436. The front plate 600 is fixed relative to the first clamp plate group 402 and the second clamp plate group 404. In other embodiments, the front plate 600 can move with one of the first clamp plate group 402 and the second clamp plate group 404 (e.g., rotate therewith, etc.). Fig. 6A Also shown is a front plate cover 600. The front plate 600 can be plastic, metal, or any material capable of covering the first and second plate sets 402, 404. The front plate 600 is configured to cover the first and second slots 414, 428. For example, the front plate 600 can prevent objects from getting stuck (e.g., caught, pinched, etc.) in the first and second slots 414, 428.

[0067] The lock 408 is coupled to each of the first cleat set 402 and the second cleat set 404. The first pin 530 is located within the first lock opening 418 of the first front cleat 310 and the first rear cleat 502 so that the first front cleat hook 411 and the first rear cleat hook 507 engage with the first pin 530.

[0068] exist Fig. 6AIn the embodiment, the expandable opening 406 is defined in a closed state (eg, the first clamping plate set 402 and the second clamping plate set 404 are oriented toward the central axis A). C The expandable opening 306 includes an upper portion 602 and a lower portion 604. The upper portion 602 is located near (e.g., below) the lock buckle 408. The lower portion 604 is defined by the first clamp 420 and the second clamp 514. For example, the lower portion 604 can be generally circular to fit the weightlifting handle 104. When the optional clamp 102 is in the closed state, the upper portion 602 of the expandable opening 406 has a smaller horizontal distance between the first clamp set 402 and the second clamp set 404. For example, the upper portion 602 of the expandable opening 406 can be smaller than the lower portion 604 of the expandable opening 406. The upper portion 602 of the expandable opening 406 can be smaller than the lower portion 604 of the expandable opening 406 to prevent the weightlifting handle 104 from moving when engaged with the optional clamp 102.

[0069] Figure 6B The optional clamp 102 is shown in an open position, wherein the optional clamp 102 is not shown. Fig. 6A The front plate cover 302 shown. Figure 6B As shown, when the optional clamp 102 is in the open state, the first clamp set 402 and the second clamp set 404 rotate about the first pivot point 412 and the second pivot point 426, respectively. For example, the first clamp set 402 and the second clamp set 404 can be relative to the central axis A C When the first plate group 402 and the second plate group 404 are pivoted outward (eg, away from the central axis A), C ), the upper portion 602 of the expandable opening expands (e.g., becomes larger, wider, etc.). For example, the horizontal distance between the inner edge of the first clamp set 402 and the inner edge of the second clamp set 404 can be greater than the horizontal distance when the optional clamp 102 is in the closed state.

[0070] In addition, if Figure 6B As shown, when the optional clamp 102 is in the open state, the first front clamp 410 pivots about the first pivot point 412 so that the first clamp 420 is located in the expandable opening 406. For example, when the optional clamp is in the open state and the weightlifting handle is disengaged from the optional clamp 102 (e.g., removed, etc.), as the first front clamp hook 411 rotates outwardly away from the central axis A, the first clamp 420 is located in the expandable opening 406. C , the first clamp 420 is rotated upward into the lower portion 604 of the expandable opening 406 .

[0071] The second cleat set 404 pivots about the second pivot point 426 so that the second clamp 514 is located within the expandable opening 406. For example, when the optional clamp is in the open state and the weightlifting handle is disengaged from the optional clamp 102, the first rear cleat hook 507 rotates outwardly away from the central axis A in the opposite direction from the first front cleat hook 411.C , the second clamp 514 is rotated upward into the lower portion 604 of the expandable opening 406 .

[0072] The first clamp 420 and the second clamp 514 are configured to engage with the weightlifting handle 104. For example, when the optional clamp 102 is in the open state and each of the first clamp 420 and the second clamp 514 is rotated into the lower portion 604 of the expandable opening 406, the first clamp set 402 and the second clamp set 404 are rotated outward (e.g., away from the central axis A). C ), widening the upper portion 602 of the expandable opening. By enlarging the upper portion 602 of the expandable opening, the optional clamp 102 is in a desired open state to receive the weight lifting handle 104. For example, the upper portion 602 of the expandable opening 406 can be inclined so as to gradually become smaller from the upper portion 602 to the lower portion 604 to guide the weight lifting handle 104 into the lower portion 604 of the expandable opening 406.

[0073] When the weightlifting handle 104 is placed in the expandable opening 406, the weightlifting handle 104 engages with each of the first clamp 420 and the second clamp 514. For example, the weightlifting handle 104 may press downward (e.g., apply a downward force, etc.) each of the first clamp 420 and the second clamp 514. When the weightlifting handle 104 applies a downward force on each of the first clamp 420 and the second clamp 514, the first clamp set 402 and the second clamp set 404 are moved relative to the central axis A. C For example, when a force is applied by the weightlifting handle 104, the first clamp 420 is forced downward, causing the first front clamp plate to rotate inward toward the central axis A. C The first clamp 420 contacts the inner edge 610 of the bottom second front clamp plate, so that the downward rotation of the first clamp 420 forces the second front clamp plate 424 to also rotate relative to the central axis A. C In addition, when the second clamp 514 is pressed downward by the weightlifting handle 104, the second clamp 514 is forced downward, causing the second rear clamp 508 to rotate inward toward the central axis A. C The second clamp 514 contacts the inner edge 612 of the bottom first rear clamp plate, so that the downward rotation of the second clamp 515 forces the first rear clamp plate 502 to also rotate relative to the central axis A. C Rotate inwards.

[0074] Figure 6B An alternative clamp 102 of the system 100 is also shown without the first portion 526 of the latch 408 . Figure 6B The inner portion 613 of the second portion 528 is shown. The inner portion 613 of the second portion 528 is located within the first portion 526 of the buckle 408. Figure 6BAs shown, the second front clamping plate 424 and the second rear clamping plate 508 may include a front annular opening 614 and a rear annular opening 616, respectively. For example, the front annular opening 614 and the rear annular opening 616 may be located at the top edge of each of the second front clamping plate 424 and the second rear clamping plate 508, opposite to the first front clamping plate hook 411 and the first rear clamping plate hook 507. The second pin 532 passes through each of the front annular opening 614 and the rear annular opening 616, and the second front clamping plate 424 and the second rear clamping plate 508 are fixedly connected to the buckle 408.

[0075] like Figures 6B to 6C As shown, the plurality of screws 416 move laterally within the first slot 414 and the second slot 428. For example, Figure 6B As shown, when the optional clamp 102 is in the open state and the weightlifting handle 104 is disengaged from the optional clamp 102, the plurality of screws 416 are located in the first slot 414 and the second slot 428 near the central axis A. C When the optional clamp 102 is in the open state, as Figure 6C As shown, a plurality of screws 416 are disposed in the first slot 414 and the second slot 428 away from the central axis A. C .

[0076] Now specific reference Figure 6C , the optional clamp 102 is in the closed state. When the optional clamp 102 is in the closed state, the first pin 530 is engaged with the first front clamp hook 411 and the first rear clamp hook 507.

[0077] The lock buckle also includes a fourth pin 608. The fourth pin 608 is fixedly coupled to the second front clamp plate 424 and the second rear clamp plate 508 within the second lock buckle opening 432. The fourth pin 608 is located between the first pin 530 and the second pin 532. The fourth pin 608 is configured to couple the lock buckle 408 to the optional clamp 102. For example, the fourth pin 608 can be located within the lock buckle 408 so that the fourth pin 608 may not be visible when viewed along the central axis Ac.

[0078] Furthermore, when in the closed state, the release lever 540 contacts each of the second front clamp plate 424 and the second rear clamp plate 508 to prevent the optional clamp 102 from being opened unnecessarily (eg, accidentally, etc.).

[0079] like Figure 6C As shown, when the optional clamp 102 is in the closed state, the plurality of screws 416 are positioned relative to the central axis A. C Positioned at the distal end of each of the first slot 414 and the second slot 428 .

[0080] Figures 7 to 10 Along the vertical axis A C The top view shows the alternative clamp 102 and the first weight set 116 of the alternative barbell clamp system 100. Figures 7 to 10 As shown, the optional fixture 102 and the first weight group 116 are placed in the first weight frame 110. Now referring specifically to Figure 7 , the optional clamp 102 and the first counterweight group 116 are placed in the first counterweight frame 110, and the optional clamp 102 is in a closed state.

[0081] like Figure 7 As shown, to release (e.g., unlock, etc.) the optional clamp 102, the user pushes down the second portion 534 of the latch 408 and the release tab 544 of the release lever 540, as indicated by arrow 700. The user then pulls upward on the narrowed end 536 of the second portion 534, as indicated by arrow 702. When the user pulls upward, the optional clamp 102 is unlocked (e.g., can be released, etc.).

[0082] Figures 8 to 9 The release of the lock 408 of the alternative clamp 102 of the alternative barbell clamp system 100 is shown. The release lever 540 and the second portion 528 of the lock 408 are pressed downward (e.g., by a user) to unlock the lock 408 from the second cleat set 404. First, the user must remove (e.g., displace, unlock, etc.) the first pin 530 from each of the first front cleat hook 411 and the first rear cleat hook 507. For example, as shown by the circular arrow 800, the first pin 530 is moved relative to the transverse axis A of the alternative clamp 102. T The first front cleat hook 411 and the first rear cleat hook 507 are laterally moved out. The first pin 530 of the lock catch 408 is then moved upwardly above the first front cleat hook 411 and the first rear cleat hook 507 to release the optional clamp 102 and open the expandable opening 406.

[0083] Once the first pin 530 and the first portion 526 of the buckle 408 are disengaged from the expandable opening 406, the weight lifting handle 104 can be removed. The weight lifting handle 104 is moved vertically upward, as indicated by the vertical arrow 900. For example, the weight lifting handle 104 is moved vertically upward a distance beyond the buckle 408.

[0084] In addition, as the weightlifting handle 104 moves out of the expandable opening 406, the weightlifting handle 104 is disengaged from each of the first cleat set 402 and the second cleat set 404. For example, the weightlifting handle 104 releases the downward pressure applied to each of the first clamp 420 and the second clamp 515. Then, the first cleat set 402 and the second cleat set 404 are relative to the transverse axis A. TFor example, the first clamping plate set 402 moves laterally in a first direction 902, while the second clamping plate set 404 moves in a second direction 904 opposite to the first direction 902. As the first clamping plate set 402 moves in the first direction 902 and the second clamping plate set 404 moves in the second direction 904, the expandable opening 406 widens (e.g., expands, enlarges, etc.). The weightlifting handle 104 can then be removed from the optional clamp 102 by pulling the weightlifting handle 104 upward as shown by arrow 906.

[0085] Fig.10 The weight lifting handle 104 is shown disengaged from the optional clamp 102. Fig.10 As shown, when the optional clamp 102 is in the open state and the weightlifting handle 104 has been removed, the first clamp 420 and the second clamp 514 protrude (e.g., extend, etc.) into the lower portion 604 of the expandable opening 406. For example, when the weightlifting handle 104 is engaged with each of the first clamp 420 and the second clamp 514, the first clamp set 402 and the second clamp set 404 are forced inwardly toward the transverse axis A. T Pivot.

[0086] Figures 11A to 11C A weightlifting handle 104 is shown, which includes an end piece 1002 for the optional barbell clamp system 100. The weightlifting handle 104 includes a first end piece 1002 and a second end piece (not shown). The end piece 1002 is removably coupled to the optional clamp 102. For example, a user can select the weightlifting handle 104 and place the first end piece 1002 in the first optional clamp 102a and the second end piece in the second optional clamp 102b.

[0087] Fig.11A 1 is a perspective view of end piece 1002. A central portion of end piece 1002 is coupled (e.g., welded, etc.) to weightlifting handle 104. End piece 1002 includes top edge 1102. Top edge 1102 is substantially flat. Top edge 1102 includes first protrusion 1104 and second protrusion 1106. First protrusion 1104 is located on a first side of end piece 1002, and second protrusion 1106 is located on a second side of end piece 1006 and opposite first protrusion 1104.

[0088] The end piece 1002 also includes a bottom edge 1108, a first curved edge 1110, and a second curved edge 1112. The bottom edge 1108 is opposite the top edge 1102 and is located below the weightlifting handle 104. The first curved edge 1110 is located on a first side of the end piece 1002, and the second curved edge 1112 is located on a second side of the end piece 1002 and opposite the first curved edge 1110. The bottom edge 1108 is configured to engage with each of the first clamp 420 and the second clamp 514.

[0089] Fig. 11B 1002, showing the top edge 1102. The top edge 1102 includes a distal end 1114 and a proximal end 1116. The distal end 1114 is flat (e.g., straight edge, etc.). When the end piece 1002 is engaged with the optional clamp 102, the distal end 1114 contacts the back plate 436.

[0090] The proximal end 1116 protrudes outward at an angle relative to a plane AA defined by the distal end 1114, which bisects the weight lifting handle 104. For example, the proximal end 1116 extends outward from each of the first protrusion 1104 and the second protrusion 1106 toward the weight lifting handle 104. The proximal end 1116 is configured to prevent any movement (e.g., near or far, up or down, left or right, etc.) of the end member 1002 between the first front clamping plate 410, the second front clamping plate 424, the first rear clamping plate 502, and the second rear clamping plate 508. For example, the proximal end 1116 is configured to wedge (e.g., fit tightly, fit firmly, etc.) between the first front clamping plate 410 and the first rear clamping plate 502, and between the second front clamping plate 424 and the second rear clamping plate 508 to prevent the end member 1002 from moving in any direction within the optional clamp 102. Specifically, the angle at which the proximal end 1116 extends outwardly prevents the end member 1002 from being moved along the central axis A when the optional clamp 102 is in the closed state. C move.

[0091] Fig. 11C 1 is a side view of the end piece 1002. The end piece 1002 includes a front face 1118 and a back face 1120. The front face 1118 is flat (e.g., planar, etc.). The front face is configured to oppose the back plate 436 when the end piece 1002 is engaged with the optional clamp 102. The back face 1120 is flat (e.g., planar, etc.) and is located above the connection point of the weightlifting handle 104. Below the connection point of the weightlifting handle 104, the back face 1120 is inclined (e.g., narrowing, etc.) as the back face 1120 extends toward the bottom edge 1108.

[0092] Reference now Figures 12 to 13, a side view of an optional clamp 102 for a weight lifting handle system 100 is shown, including an end piece 1002 of a weight lifting handle 104, a proximal housing end 128, and an optional clamp 102. The proximal housing end 128 of the first counterweight shell 125 is shown connected to a coupling portion 129. The coupling portion 129 is connected to the top of the proximal housing end 128. A plurality of optional counterweights 106 are part of the first counterweight group 116 and are shown below the coupling portion 129. The plurality of optional counterweights 106 are coupled to the counterweight shell 125 by any form of connection (e.g., selective connection, detachable connection, etc.). For example, the counterweight shell 125 may include a rod 1202 extending from the proximal housing end 128 to the distal housing end 127. The rod 1202 may be configured to selectively connect the plurality of optional counterweights 106 to the counterweight shell 125.

[0093] The proximal housing end 128 is adjacent (eg, equilateral) to the back plate 436. The back plate 436, the first rear clamping plate 502, and the second rear clamping plate 508 define an end piece cavity 1302. The end piece cavity 1302 is configured to receive the end piece 1006 of the weightlifting handle 104.

[0094] The optional clamp 102 also includes a plurality of bushings 1304. The plurality of bushings 1304 extend from the back plate 436 through each of the first rear clamping plate 502, the first front clamping plate 410, the second rear clamping plate 508, the second front clamping plate 424, and the front plate 600. The plurality of bushings 1304 are configured to receive the plurality of screws 416 that couple the first clamping plate set 402 and the second clamping plate set 404 to each of the back plate 436 and the front plate 600.

[0095] The plurality of bushings 1304 include a lower bushing 1304a and an upper bushing 1304b. The lower bushing 1304a is located at the lower half of the back plate 436. The upper bushing 1304b is located at the upper half of the back plate 436 and above the lower bushing 1304a.

[0096] Fig.13 An alternative fixture 102 is shown with the end piece 1006 positioned within the end piece cavity 1302. The first curved edge 1110 and the second curved edge 1112 engage the lower bushing 1304a once the end piece 1006 is fully inserted into the end piece cavity 1302. For example, when the end piece 1006 is properly positioned within the end piece cavity 1302 of the alternative fixture 102, the first curved edge 1110 and the second curved edge 1112 rest against (e.g., contact, etc.) the lower bushing 1304a.

[0097] In addition, when the end piece 1002 is fully engaged with the optional clamp 102, each of the first protrusion 1104 and the second protrusion 1106 engages with the upper bushing 1304b. For example, the first protrusion 1104 and the second protrusion 1106 can be placed on the top edge of the upper bushing 1304b. The lower bushing 1304a engages with each of the first curved edge 1110 and the second curved edge 1112, and the upper bushing engages with each of the first protrusion 1104 and the second protrusion 1106, which helps to properly guide the end piece 1006 into the end piece cavity 1302.
