The accompanying drawings, which are incorporated in and constitute a part of this disclosure, illustrate embodiments and together with the description, serve to explain the principles of the embodiments. With reference to these matters, one of ordinary skill in the art will understand other possible embodiments and advantages of the present utility model. The components in the figures are not drawn to scale and like reference numerals are generally used to designate like components.

The utility model will now be further described with reference to the drawings and detailed description.

First embodiment:

referring to fig. 2 to 4, a first embodiment of an exercise apparatus with a rotary resistance-adjusting device according to the present utility model is a multi-functional pulley trainer. The sports equipment with the rotary type resistance modulation device comprises a frame unit 2, an operation group 3, a pulley linkage mechanism 4 and a rotary type resistance modulation device 500.

The frame unit 2 includes a base 21 extending along a left-right direction X, a supporting frame 22 extending upward from the base 21 along an up-down direction Z, a top seat 23 connected to the top end of the supporting frame 22, and two guide rails 24 respectively located at the left and right sides of the supporting frame 22 and connecting the base 21 and the top seat 23.

The operating group 3 can be operatively arranged to the rack unit 2. The operating set 3 has two adjusting blocks 31 which can be moved along the guide rails 24 at fixed points, respectively, and two operating members 32 which are driven by the adjusting blocks 31, respectively. The height of the adjusting blocks 31 can be adjusted by the user according to different training positions, so that the user can operate each operating member 32 with one hand, two hands or one foot for weight training, such as chest clamping, high back pull-down, sitting rowing, leg abduction, etc. The first embodiment is a multi-functional pulley trainer, for example, the present utility model can be used as a force trainer such as an abdomen anteflexion machine, a leg trainer, a shoulder pushing trainer, a rowing machine, a butterfly chest trainer, etc., so that the operating member 32 can be a pull ring, a pull rod, a push rod, a radial arm, a rotating seat, a rope or other elements which can be used for exerting force, and the number of the operating members 32 can be one or more than two. Since the detailed linkage of the operation set 3 is the prior art and has various changes, those skilled in the art can deduce the expansion details according to the above description, and therefore, the description is not repeated.

The pulley linkage mechanism 4 (as one of the conducting linkages 4) is disposed on the frame unit 2 and has one conducting end connected to the operating members 32 and the adjusting blocks 31 of the operating set 3, the pulley linkage mechanism 4 is composed of a plurality of pulleys 41 and a plurality of cables 42, wherein two of the cables 42 are connected to the operating members 32, and when a user pulls the operating members 32 and moves away from the adjusting blocks 31, the cables 42 are pulled and the pulley linkage mechanism 4 is linked to operate. The pulley interlock mechanism 4 as shown in fig. 2 reveals a specific structural arrangement of the pulley 4 and the cable 42, but the structural arrangement of the pulley 4 and the cable 42 of the pulley interlock mechanism 4 can be adapted according to the variation of the size and shape of the frame unit 2, and this part of the technology is generally known to those skilled in the art and will not be developed in detail herein. It will be appreciated that in other variations, the pulley interlock mechanism 4 may be comprised of a plurality of gears, racks, and a plurality of chains or belts. Since the detailed linkage of the pulley linkage mechanism 4 is the prior art and has various changes, those skilled in the art can deduce the expansion details from the above description, and therefore, the description is not repeated.

The rotary modulation resistance device 500 is mounted on the frame unit 2 and connected to the other conductive end of the pulley linkage mechanism 4, and the rotary modulation resistance device 500 is used for providing training resistance to the operation set 3 and comprises two dampers 51, a sliding rail 52, a fixed seat 53 and a movable seat set 6.

The dampers 51 are fixed to the left and right sides of the support frame 22 and extend in the up-down direction Z, and the damper 51 on the left side has two ropes extending from the bottom end and being pulled to provide resistance, which are referred to as resistance ropes 511 because they are both involved in resistance adjustment, and the damper 51 on the right side also has two ropes extending from the bottom end and being pulled to provide resistance, one of which is involved in resistance adjustment, and the other of which is extending from the bottom end and being constantly connected to the movable seat group 6 to provide initial resistance, so that they are respectively referred to as resistance ropes 511 and linkage ropes 512 according to functions. That is, the first embodiment shares one of the linking cable 512 and three of the resistance cables 511. The pulling resistance of the connecting cable 512 of the damper 51 on the right side is 5kg, the pulling resistance of the other resistance cable 511 is 5kg, and the pulling resistances of the two resistance cables 511 of the damper 51 on the left side are 10kg. Each end of the three resistance cables 511 has a hooking member 513 so that 0 to 3 of them can be selectively hooked by the movable seat group 6, thereby realizing various training resistance files as follows.

It should be noted that, the damper 51 may be a vacuum piston damper of the prior art, as disclosed in the patent publication WO2021142509 A1. Other types of dampers, such as cylinder dampers, can be selected as the damper, and the damper is applicable as long as the force application end of the damper can apply force through rope connection.

The slide rail 52 is mounted on the frame unit 2 and extends along the up-down direction Z, and the slide rail 52 is fixed on the support frame 22 and located between the dampers 51.

Referring to fig. 3 to 5, the fixing base 53 is fixed at the bottom end of the supporting frame 22, and the fixing base 53 has a plurality of through holes 531 spaced apart to allow the resistance cables 511 and the link cable 512 to movably pass through. The corresponding link rope 512 may be a generally cylindrical through hole, and the through holes 531 corresponding to the resistance ropes 511 are stepped holes having a wide upper portion and a narrow lower portion, so that the hooking pieces 513 passing through the ends of the resistance ropes 511 of the through holes 531 can hover without falling down. The hook 513 of each drag rope 511 passes through the fixing seat 53 and exposes the corresponding through hole 531. The connecting cable 512 of the first embodiment passes through the fixing base 53 along an axis L, and the hook members 513 of the three drag cables 511 are arranged in a triangle around the central axis L.

The movable seat set 6 is connected with one of the cables 42 of the pulley linkage mechanism 4, so that the operation set 3 is driven by the pulley linkage mechanism 4 to move up and down along the axis L relative to the frame unit 2 and the fixed seat 53 under the operation of a user. The movable seat set 6 is used for pulling the linkage cable 512 or the linkage cable 512 and the resistance cables 511, and the movable seat set 6 is provided with a movable seat 61 driven by the pulley linkage mechanism 4, a shaft seat 62 fixed at the bottom end of the movable seat 61 along the axis L and used for fixing the linkage cable 512, and a rotating seat 63 rotatably sleeved on the shaft seat 62 and driven by the movable seat 61.

The movable seat 61 has a seat body 611, a rotating wheel 612 rotatably mounted on the seat body 611 for winding one of the cables 42 of the pulley linkage mechanism 4, and a sliding block 613 connected to the seat body 611 and slidably disposed on the sliding rail 52. When the movable seat 61 is driven by the pulley linkage mechanism 4 to move up and down, the sliding block 613 slides along the sliding rail 52, so that the movable seat set 6 can move up and down stably without shaking or swinging.

It should be noted that, the pulley linkage mechanism 4 in this embodiment is used as a transmission linkage mechanism for transmitting the displacement operation of the operation set 3 to the movable seat set 6, and in the case of using other gear train linkage mechanisms such as a rack and pinion as the transmission linkage mechanism, the rotating wheel 612 may be replaced with a corresponding transmission element such as a transmission gear.

The shaft seat 62 has a shaft portion 621 fixed on the movable seat 61 and for the interlocking cable 512 to be screwed and fixed, and a lower shaft disc 622 formed on the bottom side of the shaft portion 621 and having a shape of a cake. The shaft 621 has a substantially cylindrical shape for rotatably mounting the rotating base 63 thereon, and a plurality of first positioning members 623 are annularly arranged on the side surface of the shaft 621, and each of the first positioning members 623 of the first embodiment is a recess. The shaft seat 62 is further provided with a yielding groove 6221 corresponding to the number and positions of the hanging pieces 513 hovering over the fixing seat 53, the shape and size of the inner cavity of the yielding groove 6221 are matched with those of the hanging pieces 513, a part of the hanging pieces 513 can be exposed through the yielding groove 6221 and can be prevented from shaking in the hanging process due to limiting constraint of a part of the hanging pieces 513, so that the rotating seat 63 can be firmly hung. Because the shaft seat 62 is fixedly connected with the bottom end of the movable seat 61, the movable seat 61 is positioned by the sliding block 613 and the sliding rail 52, so that the movable seat set 6 is ensured not to deflect when falling back to the fixed seat 53, and the positions of the yielding grooves 6221 of the shaft seat 62 can always correspond to the hook pieces 513.

Referring to fig. 5 to 7, the rotating base 63 rotatably sleeved on the shaft base 62 can rotate around the axis L relative to the shaft base 62 and is used for hooking the resistance cables 511, and the upper and lower ends of the rotating base 63 are open and include an outer limiting wall 601 and a surrounding wall 602 surrounding the outer limiting wall 601 and extending towards the moving base 61. The outer limiting wall 601 is formed with a plurality of first hooking portions 631 arranged in a circumferential direction around the axis, and a plurality of first abdicating portions 632 formed between the two first hooking portions 631. The first hook portions 631 are closer to the central axis L than the first abdicating portions 632, and one combination of the different first hook portions 631 and/or the first abdicating portions 632 is used to selectively hook or not hook the hook members 513 of the resistance cables 511 by rotating the rotating base 63. The first embodiment has five first hook portions 631 and five first abdicating portions 632, and the length of the first hook portions is longer or shorter, so that 6 hook combinations can be formed corresponding to three hook members 513 arranged in a triangle shape in the circumferential direction, which are respectively: first gear: 5 kg+0kg+0kg+0kg=5 kg; second gear: 5kg+5kg+0kg+0kg=10kg; third gear: 5kg+0kg+10kg+0kg=15 kg; fourth gear: 5kg+5kg+10kg+0kg=20 kg; fifth gear: 5kg+0kg+10kg+10kg=25kg; sixth gear: 5 kg+5kg+10kg+10kg=30 kg. The surrounding wall 602 has a second positioning member 633 for engaging one of the first positioning members 623 of the shaft seat 62, where the second positioning member 633 of the first embodiment is a positioning bead, and the positioning bead of the second positioning member 633 is engaged with the recess of the first positioning member 623 to implement gear positioning during the rotation adjustment operation of the rotating seat 63.

Referring to fig. 8 to 10, in detail, each of the hooks 513 has a head 514, a neck 515 connected to the lower portion of the head 514 and reduced inward, and a large outer diameter portion 516 connected to the lower portion of the neck 515 and expanded outward. The large outer diameter portion 516 abuts against the step surface of the step hole 531 of the through hole 531 of the fixing base 53, so that the hook 513 is always suspended and exposed to the fixing base 53.

The ends of the resistance cables 511 are fixedly connected to a screw 5111, and then are screwed and fixed to the lower end of the outer diameter portion 516 by a nut 5112, so as to fixedly connect the resistance cables 511 with the hook members 513. Similarly, the end of the link cable 512 is fixedly connected to a screw 5121 by a press-riveting method, and then is screwed and fixed to the lower end of the shaft 621 by a nut 5122, so as to realize the fixed connection of the link cable 512 and the shaft seat 62.

The rotating base 63 can rotate relative to the fixed base 53 and selectively hook the resistance cables 511, as shown in fig. 9, when the rotating base 63 moves towards the fixed base 53, the hook members 513 of the resistance cables 511 extend into the first abdicating portions 632 of the rotating base 63, and the resistance cables 511 are not hooked. Then, as shown in fig. 10, the rotating base 63 is rotated until one of the first hook portions 631 extends into the neck 515 of the hook 513 of one of the drag ropes 511, and the head 514 of the hook 513 abuts against the first hook portion 631, at this time, the drag rope 511 is hooked by the rotating base 63.

Therefore, when the user pulls the operating members 32, the sum of the pulling resistances of the drag cable 511 and the link cable 512 hooked by the rotating seat 63 is overcome, so as to link the movable seat set 6 to move upwards, thereby achieving the effect of weight training.

Referring to fig. 11, the left-most rotary seat 63 is in an initial state, and the resistance cables 511 are not hooked, so that the training resistance is only 5kg from the linkage cable 512. If the training resistance is to be increased, the user only rotates the rotating base 63 counterclockwise to let one of the first hook portions 631 extend into the neck portion 515 of one of the hook members 513, and then the rotating base 63 hooks the resistance cable 511 with a resistance of 5kg, so that the training resistance is increased to 10kg. If the rotation base 63 is rotated counterclockwise, two or three resistance cables 511 can be selectively hooked, and the training resistance can be adjusted to 20kg or 30kg. The figure only shows a few adjustment positions, and the training resistance varies more according to the number of the resistance cables 511 or the resistance value, and will not be described in detail here.

The utility model can enable the first hook parts 631 to selectively hook the hook pieces 513 by rotating the rotating seat 63 so as to change the training resistance, and the adjustment mode of the training resistance is simple and convenient.

Second embodiment:

referring to fig. 12 to 14, a second embodiment of the present utility model is similar to the first embodiment, and the main difference is that a rotary modulation resistance device implemented by the movable seat set 6 and the fixed seat 53, which are slightly different from the first embodiment, is:

the fixing base 53 is also fixed at the bottom end of the supporting frame, and the fixing base 53 still has a plurality of conventional through holes spaced apart and respectively allowing the connecting cable 512 to pass through, and through holes allowing the resistance cables 511 to movably pass through and hover over the holes. The ends of the resistance cables 511 also have a hook 513, the hook 513 also having a neck and head that can be hooked. Similarly, the linkage cable 512 passes through the fixing base 53 along the center of an axis L, and the three hooks 513 of the resistance cable 511 are arranged in a triangle around the center of the axis L. The difference is that the height of the fixed seat 53 is higher and the depth of the through hole is deeper, so that the exposed height of the hooking members 513 is lower, and the hooking members 513 of the resistance cables 511 are stably hovered and placed, which is beneficial for the movable seat group 6 to stably hook.

The movable seat set 6 is used for pulling the linkage rope 512 or the linkage rope 512 and the resistance ropes 511 passing through the fixed seat 53. The movable seat set 6 also has a movable seat 61 driven by the pulley linkage mechanism, a shaft seat 62 fixed at the bottom end of the movable seat 61 along the axis L and fixed by the linkage cable 512, and a rotating seat 63 rotatably sleeved on the shaft seat 62 and driven by the movable seat 61.

The movable seat 61 also includes a seat body 611, a rotating wheel 612 rotatably mounted on the seat body 611 and provided for winding one of the cables of the pulley linkage mechanism, and a sliding block (not shown) connected to the seat body 611 and slidably disposed on the sliding rail to enable the movable seat set 6 to stably move up and down without shaking or swaying. By positioning the sliding block and the sliding rail, the movable seat set 6 is ensured not to deflect when falling back to the fixed seat 53, and the shaft seat 62 can always correspond to the hook pieces 513.

In the movable seat group 6 of this embodiment, the structure of the shaft seat 62 is slightly different from that of the first embodiment, and the shaft seat 62 includes: the movable seat 61 is provided with a shaft portion 621 for being fixedly connected with the movable seat 61 and being screwed with the interlocking rope 512, a lower shaft disc 622 formed on the bottom side of the shaft portion 621 and having a circular cake shape, and an upper shaft disc 624 formed on the top side of the shaft portion 621 and having a circular cake shape. The shaft 621 is substantially cylindrical in shape for the rotary seat 63 to be rotatably sleeved thereon, and after the rotary seat 63 is sleeved on the shaft 621, the upper shaft 624 is fixedly connected to the top side of the shaft 621, and the upper shaft 624 is fixedly connected to the movable seat 61 provided with the rotary wheel 612 in the seat 611 by welding. Thus, the lower shaft plate 622, the shaft portion 621 and the upper shaft plate 624 form a horizontal H-shaped shaft seat 62 and are fixedly connected to the lower end of the movable seat 6, and the rotary seat 63 can rotate along the shaft portion 621 relative to the horizontal H-shaped shaft seat 62.

Wherein the upper plate 624 has a first positioning member 623'. The first positioning member 623' of the second embodiment is a positioning bead protruding downward toward the positioning wall 604 of the upper end of the rotating seat 63. The lower shaft plate 622 of the shaft seat 62 is provided with relief holes 6221' corresponding to the number and positions of the hooking members 513 hovering over the fixed seat 53. The shape and size of the relief hole 6221 'are matched with the round hole of the hook 513, the neck and the head of the upper half part of the hook 513 are exposed through the relief hole 6221', and the hook 513 is not easy to shake in the hooking process due to the limit constraint of the lower part, so that the rotation seat 63 is ensured to firmly hook.

The rotating seat 63 includes: an outer limiting wall 601 at the lower end of the drawing, an inner limiting wall 603 spaced inside the outer limiting wall 601, a positioning wall 604 at the upper end of the drawing for positioning engagement with the upper shaft plate 624, a surrounding wall 602 connecting the outer limiting wall 601 and the positioning wall 604, and a center sleeve 605 disposed at the inner center of the surrounding wall 602. The outer limiting wall 601 is connected with the surrounding wall 602, the inner limiting wall 603 is connected with the central sleeve 605, the central sleeve 605 is movably sleeved on the shaft portion 621 of the shaft seat 62, and the outer limiting wall 601 and the inner limiting wall 603 together form a selective hooking structure capable of selectively hooking the hooking member 513. The positioning wall 604 is formed with a plurality of second positioning members 633 'for engaging the first positioning members 623', and each of the second positioning members 633 'of the second embodiment is a plurality of concave holes arranged at intervals of circular arc shape for matching with the positioning beads protruding downward of the first positioning member 623', thereby realizing gear positioning during the rotation adjustment operation of the rotating seat 63.

Referring to fig. 14, the outer limiting wall 601 is formed with a plurality of first hook portions 631 disposed in a circumferential direction around the axis, and a plurality of first abdication portions 632 formed between the two first hook portions 631. The inner limiting wall 603 also forms a plurality of second hook portions 634 disposed at intervals and surrounding the inner sides of the first hook portions 631 at positions corresponding to the first hook portions 631 and the first abdication portions 632, and a plurality of second abdication portions 635 formed between the two second hook portions 634. The first hook portions 631 are closer to the central axis than the first abdicating portions 632, the second hook portions 634 are farther from the central axis than the second abdicating portions 635, the second hook portions 634 are aligned with the first hook portions 631, the second abdicating portions 635 are aligned with the first abdicating portions 632, and the distance between each second hook portion 634 and the corresponding first hook portion 631 is smaller than the distance between each second abdicating portion 635 and the corresponding first abdicating portion 632. Thus, by rotating the rotating base 63, one of the first hook portions 631 and the second hook portions 634 and/or the first abdicating portion 632 and the second abdicating portion 635 can be combined to selectively hook or not hook the hook members 513 of the resistance cables 511.

Referring to fig. 15, each of the second hook portions 634 of the rotating base 63 and the corresponding first hook portion 631 are used together to hook on two opposite sides of the corresponding hook 513 at the same time, and since two opposite sides of the hook 513 are hooked by the rotating base 63, the hook mode of the hook 513 is smoother and not inclined than the first embodiment, and the stability of the hook can be increased.

Referring to fig. 16, the rotary seat 63 of the second embodiment is in an initial state at the leftmost side of the drawing, and the resistance cables 511 are not hooked, and the training resistance is only 5kg from the linkage cable 512. Then, the rotating base 63 is rotated anticlockwise, so that one of the first hook portions 631 and the second hook portion 634 matched with the first hook portion 631 extend into the neck portion 515 of one of the hook members 513, and the hook member 513 with the resistance of 5kg is hooked by the rotating base 63, and the training resistance is 10kg. By continuing to rotate the rotating base 63 counterclockwise, two or three resistance cables 511 can be sequentially hooked, and the training resistance can be adjusted to 20kg or 30kg. The figures illustrate only a few adjustment positions, and the training resistance varies more depending on the number of the resistance cables 511 or the resistance value, and will not be described in detail herein.

The second embodiment also enables the first hook portions 631 and the second hook portions 634 to selectively hook the hook members 513 by rotating the rotating base 63, so as to change the training resistance, and the way of adjusting the resistance by rotation is simple and convenient.
