Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically to a standing thigh abduction trainer and its cable transmission mechanism. Background Technology

[0002] A thigh abduction trainer is a fitness device designed to effectively enhance the strength and flexibility of the thigh muscles. During training, the legs are extended from the center outwards against resistance. However, typical thigh abduction trainers are seated, as seen in Chinese patent publication CN305870494S, where the user sits on a fixed seat, unable to adjust their posture as the legs extend outwards. Standing thigh abduction trainers have gradually emerged on the market. The user stands on the left and right footplates in a semi-squatting position, extending their legs from the center outwards. During this extension, the user's posture and center of gravity can be adjusted according to the degree of extension. However, existing standing thigh abduction trainers use two screws to secure the adjustment ends of the pull ropes on both sides, relying on friction between the screws and the ropes for fixation and adjustment. This method is prone to the pull ropes coming undone. Utility Model Content

[0003] The purpose of this invention is to provide a standing thigh abduction trainer and its pull rope transmission mechanism, which can conveniently adjust the tension of the pull rope and enhance the positional stability of the pull rope tension adjustment end after adjustment.

Detailed Implementation

[0029] To make the above-mentioned features and advantages of this utility model more apparent and understandable, specific embodiments are described below in conjunction with the accompanying drawings for detailed explanation.

[0030] like Figures 1-7 As shown, this embodiment provides a standing thigh abduction trainer, including a frame 100, a pedal assembly 200, a leg pad assembly 300, a resistance source 400, and a rope transmission mechanism 500.

[0031] In this embodiment, the frame 100 includes a horizontal frame placed on the ground and a vertical frame fixedly installed at the front end of the horizontal frame. The pedal assembly 200 includes a left pedal and a right pedal respectively rotatably mounted on the horizontal frame. A rotating column 201 is respectively provided at the rear end of the left pedal and the rear end of the right pedal. The rotating column 201 is rotatably mounted on a fixed column at a corresponding position on the horizontal frame via bearings, and the two rotating columns 201 are connected by a movable linkage assembly. Two leg pad assemblies 300 are provided and fixedly installed on the left and right pedals respectively. The exerciser places both feet on the left and right pedals, with their thighs pressing against the leg pad assemblies 300, and then extends outwards, causing the left and right pedals to rotate synchronously in opposite directions. During the synchronous reverse rotation, the resistance from the resistance source 400 is transmitted to the pedal assembly 200 through the rope transmission mechanism 500, overcoming resistance during training. Additionally, a handrail is provided on the side of the vertical frame facing the pedal assembly 200 for the exerciser to hold onto.

[0032] The resistance source 400 can be one or more of the following: gravity resistance source, elastic resistance source, electromagnetic resistance source, electric resistance source, and pneumatic resistance source. Specifically, in this embodiment, the resistance source 400 is a hanging counterweight among gravity resistance sources. Specifically, the resistance source 400 includes a bell hanger and a bell plate (not shown in the figure) hanging on the bell hanger. The rear end of the bell hanger is rotatably mounted on the upright frame via a rotating shaft. The bell hanger rotates up and down around the rotating shaft. The upright frame is provided with a support arm at the position corresponding to the bell hanger, and the weight of the bell hanger rests on the support arm.

[0033] In this embodiment, the pull rope transmission mechanism 500 is connected between the pedal assembly 200 and the resistance source 400. It includes a pull rope 53, a first winding reel 51 that drives the resistance source 400, and a second winding reel 52 that drives the pedal assembly 200. Specifically, the first winding reel 51 is fixedly mounted on a rotating shaft and moves synchronously with the bell hanger. The second winding reel 52 is fixedly mounted on the rotating column 201 of the pedal assembly 200 and rotates synchronously in the same direction with the rotating column 201. Since the left and right pedals move synchronously in opposite directions under the action of the movable linkage assembly, the second winding reel 52 only needs to be mounted on the rotating column 201 of the left pedal or the rotating column 201 of the right pedal. Figure 3 The second rope reel 52 is located on the rotating column 201 of the right pedal. When the pedal assembly 200 unfolds outward, the second rope reel 52 rotates in the space between the left and right pedals, thereby pulling the pull rope 53 and transmitting it to the first rope reel 51, which pulls the first rope reel 51 and the bell hanger upward. At this time, the weight of the bell on the bell hanger acts as a resistance.

[0034] The first rope reel 51 has a first rope groove 511 on its outer periphery. The first end of the pull rope 53 is wrapped around the first rope groove 511 and detachably installed on the first rope reel 51. The first end of the pull rope 53 serves as the tension fixing end of the pull rope 53 in this embodiment. The first end of the pull rope 53 is fixed to the first rope reel 51 in this embodiment by a snap-fit ​​engagement method: a snap-fit ​​block 513 is fixedly provided in the first rope groove 511. The snap-fit ​​block 513 is located in the first rope groove 511 away from the second end of the pull rope 53 along the direction of the pull rope 53. A snap-fit ​​hole is provided on the snap-fit ​​block 513. The first end of the pull rope 53 passes through the snap-fit ​​hole and is snapped with the side of the snap-fit ​​block 513 away from the second end of the pull rope 53 by a snap-fit ​​block 531 fixed to the end of the first end of the pull rope 53. In this way, the first end of the pull rope 53 is fixed on the first rope reel 51 and the connection position is fixed relative to the first rope reel 51. Furthermore, to reduce the likelihood of the pull rope 53 detaching from the first rope groove 511 of the first rope winding reel 51, the first rope winding reel 51 is provided with a first anti-detachment component 512 extending to the outside of the groove opening of the first rope groove 511 at the point where the pull rope 53 passes. The first anti-detachment component 512 prevents the pull rope 53 from detaching from the first rope groove 511. The first anti-detachment component 512 is an L-shaped structure with one end fixed to the first rope winding reel 51 by a screw and the other end extending to the outside of the groove opening of the first rope groove 511, or a U-shaped structure with both ends fixed to the first rope winding reel 51 by screws and the middle part extending to the outside of the groove opening of the first rope groove 511. To facilitate the disassembly and assembly of the first end of the pull rope 53, a window 514 is provided on the end face of the first rope winding reel 51 at the position corresponding to the locking block 513. The connection between the locking block 531 and the first end of the pull rope 53 can be released or fixed at the window 514. Preferably, the locking block 531 is fixed to the first end of the pull rope 53 by a pressing method.

[0035] The second rope reel 52 has a second rope groove 521 on its outer periphery. The second end of the pull rope 53 serves as the tension adjustment end of the pull rope 53 in this embodiment. The second end of the pull rope 53 passes through the second rope groove 521 and its end is connected to a bolt 532. The second rope reel 52 is provided with a bolt mounting seat 520. The bolt 532 is adjustablely inserted into the bolt mounting seat 520 and locked in place by two nuts 533. One nut 533 is on the front side of the bolt mounting seat 520 and the other nut 533 is on the rear side of the bolt mounting seat 520. By adjusting the position of the bolt 532 on the second rope reel 52, the tension of the pull rope 53 can be adjusted. Furthermore, to reduce the occurrence of the pull rope 53 detaching from the second rope groove 521 of the second rope reel 52, the second rope reel 52 is provided with a second anti-detachment component 522 extending to the outside of the groove opening of the second rope groove 521 at the point where the pull rope 53 passes. The second anti-detachment component 522 prevents the pull rope 53 from detaching from the second rope groove 521. The second anti-detachment component 522 is an L-shaped structure with one end fixed to the second rope reel 52 by a screw and the other end extending to the outside of the groove opening of the second rope groove 521, or a U-shaped structure with both ends fixed to the second rope reel 52 by screws and the middle part extending to the outside of the groove opening of the second rope groove 521. Preferably, the bolt 532 is a hollow column, and the second end of the pull rope 53 passes through the bolt 532 with a limit block pressed at the end of the second end.

[0036] The first rope reel 51 is an eccentric or circular reel, and the second rope reel 52 is composed of a bolt mounting base 520 and a rope reel body with a second rope groove 521. The rope reel body is an eccentric or circular reel, and the bolt mounting base 520 is located at the outlet of the second rope groove 521 of the rope reel body. Figure 1 and Figure 3 The rope reel bodies of the first rope reel 51 and the second rope reel 52 shown are eccentric reels.

[0037] Furthermore, to make the path of the pull rope 53 on the frame 100 more reasonable, the pull rope transmission mechanism 500 also includes a pulley block. The pull rope 53 passes through the pulley block and is guided and redirected by the pulley block. The pulley block includes a horizontal fixed pulley 54 with its central axis perpendicular to the plane of the right pedal and a vertical fixed pulley 55 with its central axis parallel to the plane of the right pedal. The horizontal fixed pulley 54 is located on the side of the vertical fixed pulley 55 closer to the second rope winding disc 52, and the horizontal fixed pulley 54 has a horizontal rope groove on its outer periphery. The vertical fixed pulley 55 has a vertical rope groove on its outer periphery. The pull rope 53 passes through the vertical rope groove and the horizontal rope groove, and the direction of the pull rope 53 between the vertical rope groove and the horizontal rope groove is tangent to the vertical fixed pulley 55. Furthermore, to reduce the occurrence of the pull rope 53 detaching from the horizontal and vertical rope grooves, the horizontal fixed pulley 54 is provided with a horizontal anti-detachment component extending to the outside of the groove opening of the horizontal rope groove at the point where the pull rope 53 passes, and the vertical fixed pulley 55 is provided with a vertical anti-detachment component extending to the outside of the groove opening of the vertical rope groove at the point where the pull rope 53 passes. The horizontal anti-detachment component prevents the pull rope 53 from detaching from the horizontal rope groove, and the vertical anti-detachment component prevents the pull rope 53 from detaching from the vertical rope groove. The structure of the horizontal and vertical anti-detachment components is the same as that of the first anti-detachment component 512, and will not be described again.

[0038] The specific structure of the first rope winding disc 51, the second rope winding disc 52, the horizontal fixed pulley 54, and the vertical fixed pulley 55 is a conventional technology in rope strength training equipment, and is briefly described here: Each includes a central body and two clamping plates located on both sides of the central body. The two clamping plates are provided with corresponding fastening holes, and the two clamping plates and the central body located between the two clamping plates are clamped and fixed as a whole by fasteners. The rope groove is located on the outer periphery of the central body. In addition, the clamping plates and the central body are provided with through holes facing each other, and are connected to the frame 100 or other components through the mounting holes.

[0039] It should be noted that in some other examples, the tension fixing end of the pull rope 53 can also be the second end of the pull rope 53 and the tension adjusting end can be the first end of the pull rope 53. In this case, the bolt mounting seat 520 is fixedly set on the first rope winding disc 51. The installation method of the tension adjusting end and the bolt mounting seat 520 is also a combination of bolts and two nuts, which will not be described in detail here.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this invention. Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this invention.
