In this embodiment, the support pad unit 20 includes a connecting frame 21 movably disposed on the side frame 11 along the vertical direction, and a support pad module 22 disposed on the connecting frame 21.

[0016] The connecting frame 21 has a mounting portion 211 extending along the front-rear direction and two side arm portions 212 connected to the mounting portion 211.

[0017] The side arm portions 212 are movably disposed on the side frames 11 along the vertical direction. In this embodiment, each side arm portion 212 has four rollers 213 that are arranged in pairs and roll in contact with the guide rods 113 of the respective side frames 11.

[0018] The support pad module 22 has a mounting base 221 disposed on the mounting portion 211, and three rollers 222 rotatably disposed on the mounting base 221 and arranged along the front-rear direction, the rollers 222 being able to be supported by the user's body. In this embodiment, the rollers 222 are made of foam material.

[0019] As shown in Figures 2, 4 and 5, the assist unit 30 is disposed on the frame unit 10 and connected to the support pad unit 20. The assist unit 30 is used to drive the support pad unit 20 to move upward.

[0020] In this embodiment, the assist unit 30 includes several counterweights 31 disposed on the front frame 12 and stacked along the vertical direction, two pulley sets 32, and two connecting ropes 33. Each pulley set 32 ​​has an initial pulley 321 pivotally mounted on each of the side arms 212 of the connecting frame 21, two intermediate pulleys 322 pivotally mounted on the upper crossbars 111 of each of the side frames 11, a high pulley 323 pivotally mounted on the front frame 12, and a final pulley 324 pivotally mounted on the front frame 12. Each linkage rope 33 has a first end 331 connected to the starting pulley 321 of each pulley group 32, a second end 332 connected to at least one counterweight 31, and an intermediate section 333 connected between the first end 331 and the second end 332. The intermediate section 333 of each linkage rope 33 is wound around the intermediate pulley 322, the high pulley 323 and the final pulley 324 of each pulley group 32.

[0021] In this embodiment, the intermediate pulleys 322 are higher than the initial pulleys 321 in the vertical direction, the high pulleys 323 are higher than the intermediate pulleys 322 in the vertical direction, the final pulleys 324 of the pulley group 32 are coaxially arranged and are located between the high pulleys 323 of the pulley group 32 in the left-right direction, and the final pulleys 324 are slightly higher than the high pulleys 323 in the vertical direction.

[0022] In this embodiment, the assist unit 30 provides an upward support force F to the support pad module 22 of the support pad unit 20 in the vertical direction (see FIG. 14). The assist unit 30 also includes an adjusting rod module 34 that can be upwardly linked to the selected counterweight 31. The second end 332 of the connecting rope 33 is connected to the selected counterweight 31 via the adjusting rod module 34. The user can change the magnitude of the upward support force F by selecting the number of counterweights 31 that are driven. The upward support force F is equal to the weight of the driven counterweights 31.

[0023] The support pad height adjustment unit 40 includes two slides 41 that are movably disposed on the height adjustment guide rods 122 along the vertical direction, an operation module 42 disposed on the slides 41, and two height segment positioning groups 43 disposed on the columns 121.

[0024] Each slide 41 has a guide section 411 that slides with a respective height adjustment guide rod 122, and a pivot section 412 that is connected to the guide section 411.

[0025] The operation module 42 has an operation lever 44 pivotally mounted on the slide 41, two adjusting pulleys 45 spaced apart on the operation lever 44 in the left-right direction, and two hooks 46 spaced apart on the operation lever 44 in the left-right direction.

[0026] Each height segment positioning group 43 has a number of segment positioning blocks 431 that are spaced apart along the vertical direction on each of the individual columns 121.

[0027] The operating lever 44 has two pivot portions 441 respectively pivotally mounted on the pivot tube portions 412 of the slides 41, a connecting portion 442 connected between the pivot portions 441, and two handle portions 443 respectively connected to the pivot portions 441.

[0028] The adjusting pulleys 45 are respectively pivotally mounted on the handle portions 443. In this embodiment, each adjusting pulley 45 is lower than the relay pulley 322 of the respective pulley group 32 in the vertical direction, and each adjusting pulley 45 is between the relay pulley 322 and the high pulley 323 of the respective pulley group 32 in the front-back direction.

[0029] The hooks 46 are respectively fixed to the outward end of the handles 443 and are respectively adjacent to the adjusting pulleys 45. Each hook 46 is selectively positioned at one of the segment positioning blocks 431 of the respective height segment positioning group 43. It can be understood that by grasping the handles 443 and rotating the operating lever 44, the user can disengage each hook 46 from the segment positioning block 431 of the respective height segment positioning group 43.

[0030] In this embodiment, the middle section 333 of each connecting rope 33 will first go down around the respective adjusting pulley 45 and then go up around the respective high-position pulley 323 of the respective pulley group 32 during the process of passing around the relay pulley 322 and the high-position pulley 323 of the respective pulley group 32. That is to say, the middle section 333 of each connecting rope 33 will sequentially be connected to the relay pulley 322, the respective adjusting pulley 45 and the respective high-position pulley 323 of the respective pulley group 32.

[0031] As shown in Figures 5, 6, and 7, the support pad height adjustment unit 40 can be operated to change the height of the support pad module 22 of the support pad unit 20 in the vertical direction via the connecting ropes 33. As shown in Figure 6, when the user selects to position each hook 46 at the lowest segment positioning block 431 of the respective height segment positioning group 43, the middle segment 333 of each connecting rope 33, which is stretched downwards by each adjusting pulley 45, can adjust the height of the support pad module 22 of the support pad unit 20. 22 moves upward to a highest position. Conversely, as shown in Figure 7, when the user selects to position each hook 46 at the highest segment positioning block 431 of the respective height segment positioning group 43, the middle segment 333 of the respective linkage rope 33, which is relaxed upward by each adjusting pulley 45, can move the support pad module 22 of the support pad unit 20 downward to a lowest position. In this way, the user can adjust the support pad module 22 of the support pad unit 20 to an appropriate upper and lower position according to their own arm length.

[0032] As shown in Figures 2, 8 and 9, the grip units 50 are disposed opposite to the frame unit 10 in the left-right direction and are lower than the support pad module 22 of the support pad unit 20 in the up-down direction.

[0033] Each grip unit 50 further includes a base 51 disposed on a separate side frame 11, an adjustment seat 52 disposed on the base 51, a grip 53 pivotally disposed on the adjustment seat 52, and two adjustment seat positioning pins 54. In this embodiment, the base 51 of each grip unit 50 is adjustablely positioned on a separate side frame 11 along the front-rear direction.

[0034] The base 51 has an adjustment guide rail 511 extending in the left-right direction and a side plate 512 connected to the adjustment guide rail 511.

[0035] The adjusting guide rail 511 has a number of adjusting seat positioning holes 513 spaced apart along the left and right direction.

[0036] The side plate 512 of the base 51 of each grip unit 50 is formed with two base positioning pins 114 corresponding to the respective side frame 11 and extending along the front-rear direction, and has a protrusion 516 for the user to grip. Each adjustment groove 514 has a plurality of grooves 515. The positioning ring groove 115 of each base positioning pin 114 is selectively engaged with one of the grooves 515 of the respective adjustment groove 514 to position the base 51 of each grip unit 50 on the respective side frame 11.

[0037] The adjustment seat 52 is adjustablely positioned on the adjustment guide rail 511 along the left-right direction. In this embodiment, the adjustment seat 52 has a guide seat portion 521 that connects to the adjustment guide rail 511, and a pivot seat portion 522 that connects to the guide seat portion 521. The pivot seat portion 522 is formed with a number of grip positioning holes 523 spaced apart along the circumferential direction. The guide seat portion 521 also has a handle 524 that can be gripped by the user.

[0038] The grip 53 is pivotally mounted on the adjustment seat 52 and is adjustablely positioned on the adjustment seat 52 in the circumferential direction. In this embodiment, the grip 53 has an abutment end 531, a pivot end 532 opposite to the abutment end 531 and pivotally mounted on the pivot seat portion 522, and a spring pin 533 disposed on the pivot end 532. The spring pin 533 is selectively positioned in one of the grip positioning holes 523 to position the grip 53 on the pivot seat portion 522.

[0039] The adjusting seat positioning pins 54 pass through the guide seat portion 521 and are selectively positioned in two of the adjusting seat positioning holes 513 to position the adjusting seat 52 on the adjusting guide rail 511.

[0040] As shown in Figures 8 and 10, when the user wants to adjust the front-back position of the grip 53 of each grip unit 50 relative to the support pad module 22 along the front-back direction, the user can use both hands to grasp the protrusion 516 of the side plate 512 of the base 51 and the lifting lug 524 of the guide seat 521 of the adjustment seat 52, so that the adjustment groove 514 of the side plate 512 of the base 51 of each grip unit 50 disengages from the base positioning pin 114 of each side frame 11. After the grip unit 50 moves to the predetermined position in the front-back direction, the base 51 and the adjustment seat 52 can be released and lowered, so that the adjustment groove 514 of the side plate 512 of the base 51 of each grip unit 50 can be re-engaged into the positioning ring groove 115 of the base positioning pin 114 of the respective side frame 11 (see Figure 9), so that each grip unit 50 can be repositioned. In this way, the user can adjust the grip 53 of the grip unit 50 to the appropriate front-back position according to his / her height and arm length.

[0041] The grips 53 of the grip units 50 can be operated to adjust their relative positions. As shown in Figure 11, the user can rotate the grips 53 relative to the adjustment base 52 to adjust the angle between the grips 53 of the grip units 50. In this way, the user can change the arm opening angle and hand grip posture to train different muscle groups in the arm. As shown in Figure 12, the user can move the adjustment base 52 and the grips 53 relative to the adjustment guide rail 511 of the base 51 to adjust the lateral spacing between the grips 53 of the grip units 50. In this way, the user can adjust the grip units 50 to an appropriate lateral position according to their height and arm length. By changing the angle and lateral spacing of the grips 53 of the grip units 50, the user can easily use different shoulder width grip widths for training.

[0042] Accordingly, as shown in Figure 13, when a user uses this embodiment to assist in performing the Russian push-up exercise, the user can initially lie face down on the roller 222 of the support pad module 22, using their own weight to press down on the support pad module 22, and hold the handles 53 of the grip units 50 with both hands and bend their arms, with their toes touching the ground. At this time, the counterweights 31 connected to the linkage ropes 33 (whose total weight is usually less than the user's weight) will be lifted up as the support pad unit 20 descends. Next, as shown in Figures 14 and 15, the user exerts force with both hands, straightens their arms and horizontally supports their body, and lifts both feet off the ground at the same time. At this time, the part of the counterweight 31 connected to the linkage rope 33 will move downward due to gravity, providing the upward support force F, causing the support pad unit 20 to rise, so that the support pad module 22 can assist the user in lifting their body in the vertical direction. In this way, the user can successfully complete the Russian push-up with a force less than their own body weight (i.e., the user's weight minus the weight of part of the counterweight 31).

[0043] It is understandable that since the upward support force F is equal to the weight of the partially driven counterweight 31, when the user chooses to drive a larger number of partially driven counterweights 31, the upward support force F will be greater, and the Russian push-up can be completed more easily. Conversely, if the fitness effect is to be enhanced, a smaller number of partially driven counterweights 31 can be chosen.

[0044] Based on the above description, the advantages of the present invention can be summarized as follows:

[0045] First, the present invention utilizes the design of the support pad unit 20 in conjunction with the assist unit 30. When the user performs Russian push-up fitness training, the assist unit 30 can provide the upward support force F. In this way, not only is it easier for the user, but the user's body can also be supported by the support pad module 22, and the center of gravity can be more stable, which helps the user to maintain the Russian push-up movement continuously, resulting in better fitness effect.

[0046] Second, the present invention utilizes the design that the height of the support pad module 22 of the support pad unit 20 can be changed via the linkage rope 33 by the operable support pad height adjustment unit 40. This design allows different users to adjust the support pad module 22 of the support pad unit 20 to an appropriate height according to their own arm length. The present invention has good applicability.

[0047] Third, the present invention utilizes the design that the base 51 of each grip unit 50 is adjustablely positioned on each of the side frames 11 along the front-back direction, which makes it convenient for different users to adjust the grip 53 of the grip unit 50 relative to the support pad module 22 to an appropriate front-back position according to their own height and arm length. The present invention has good applicability.

[0048] Fourth, the present invention utilizes the design that the adjustment seat 52 of each grip unit 50 is adjustablely positioned on the base 51 along the left-right direction, and the grip 53 is adjustablely positioned on the adjustment seat 52 along the circumferential direction. The grips 53 of the grip units 50 can be operated to adjust their relative angle position and relative left-right position, which makes it convenient for users to train with different arm opening angles, different hand grip postures and different shoulder width grip distances. The present invention has good applicability.

[0049] In summary, the Russian push-up fitness device of the present invention not only allows users to complete the Russian push-up movement with less effort, but also helps users to maintain the Russian push-up movement continuously, resulting in better fitness effects. It is also suitable for different users and has a wide range of applications, so it can indeed achieve the purpose of the present invention.
