Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically to a movable support component for a lifting training machine. Background Technology

[0002] Pressing training machines, including incline chest press machines, supine chest press machines, and seated shoulder press machines, are generally constructed with a movable arm hinged to a frame. The weight is adjusted by adding barbell plates or counterweight plates to the movable arm, and a seat or lying board is installed on the frame. The trainee pushes the movable arm up and down to achieve the effect of exercising muscles.

[0003] Chinese patent document CN214181609U discloses a recumbent fitness device with an assistive function. The assistive mechanism and the transmission component are connected by a linkage mechanism. When the user touches the assistive mechanism downwards, the transmission component rises linearly through the linkage mechanism and guide sleeve. The rising transmission component can assist in supporting the adjustable hanging plate arm mechanism. Another Chinese patent document CN219090992U discloses a double-track incline chest press trainer. The foot pedal frame is connected to the support frame through a linkage mechanism, allowing the foot pedal frame to drive the support frame upwards via the linkage mechanism. The vertical movement of the support frame is limited by a sliding sleeve.

[0004] Both types of pressing machines disclosed above utilize assist mechanisms to help trainees push upwards more effectively at the start of the press. However, firstly, because the assisting support only moves up and down, it remains within the upward and downward pressing path of the arm, limiting the arm's maximum low-position height and failing to meet the varying range and intensity needs of different trainees. Secondly, since the height of the assisting support is the starting height of the arm, this starting height should not be too high to achieve muscle training goals. This results in a starting height that is difficult for the trainee to exert force at, requiring upward assistance. Therefore, it is necessary to develop a mechanism that allows trainees to exert force from a suitable starting height without interfering with the downward pressing path required for the intensity of the arm exercise. Utility Model Content

[0005] The purpose of this invention is to provide a movable support component for a press training device that allows the exerciser to exert force from a suitable starting height without interfering with the downward pressing path required for the intensity of the arm exercise.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A movable support assembly for a press trainer, wherein the support rod of the movable support assembly swings back and forth to have a support position for supporting the arm of the press trainer and an avoidance position that is offset from the up and down movement path of the arm of the press trainer.

[0008] Preferably, the movable support assembly includes a foot pedal, a connecting rod, a rotating support frame, and a return member. The foot pedal has a first hinge portion that is hinged to the frame of the press trainer and a second hinge portion that is movably connected to the connecting rod. The rotating support frame includes a rotating crossbar that is horizontally and rotatably mounted on the frame of the press trainer and a support rod fixed on the rotating crossbar. The rotating crossbar is connected to the second hinge portion via a connecting rod. The support rod swings back and forth between a clearance position that avoids the lifting arm of the press trainer and a support position that supports the lifting arm of the press trainer, as the rotating crossbar rotates. The return member acts on the foot pedal or the connecting rod to cause the support rod to swing away from the foot pedal to the clearance position. A first limiting structure is provided between the foot pedal and the frame or between the rotating support frame and the frame to maintain the support position.

[0009] Preferably, a second limiting structure is provided between the foot pedal frame and the frame or between the rotating support frame and the frame to maintain a clearance position.

[0010] Preferably, both ends of the rotating crossbar are mounted on the frame via bearings with mounting seats.

[0011] Preferably, a support body is fixedly installed at the upper end of the support rod.

[0012] Preferably, the return element is a gas spring.

[0013] Preferably, the pedal frame is provided with pedal rods at both ends on the side away from the connecting rod. Stepping on the pedal rod causes the pedal frame to rotate around the first hinge and the support rod to swing to the support position.

[0014] Preferably, the foot pedal frame is provided with a cushioning pad at the position where it contacts the frame after rotating around the first hinge.

[0015] Preferably, the number of support rods matches the number of booms.

[0016] Preferably, the number of support rods is one or two.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] Compared to traditional support structures that only move up and down, this invention innovatively proposes a movable support component that swings back and forth between a support position and an avoidance position. When in the support position, it supports the moving arm, while in the avoidance position, it does not interfere with the arm's vertical movement. This allows the movable support component to be set at a suitable support height for the arm, resulting in a suitable starting height for force exertion. Furthermore, by offsetting the arm's vertical movement path during training, it allows the exerciser to train below the aforementioned starting height, without limiting the maximum range of motion. This movable support component is suitable for use on bench press machines, incline seated chest press machines, seated shoulder press machines, and other pressing machines.

[0025] 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.

[0026] like Figures 1-3 As shown, this embodiment provides a movable support component for a bench press trainer, which is installed on the frame of the bench press trainer. The movable support component has a support position and a avoidance position. When the movable support component is in the support position, it can be used to contact the movable arm 101 of the bench press trainer to realize the function of supporting the movable arm 101. When the movable support component is in the avoidance position, it is offset from the vertical movement path of the movable arm 101 of the bench press trainer to realize the function of avoiding the movable arm 101.

[0027] In this embodiment, the movable support assembly includes a foot pedal frame 10, a connecting rod 20, a rotating support frame, and a return member 40. The foot pedal frame 10 has a first hinge portion 11 that is hinged to the frame of the supine chest press trainer and a second hinge portion 12 that is movably connected to the connecting rod 20. The second hinge portion 12 is below the first hinge portion 11, so that the foot pedal frame 10 can rotate back and forth around the first hinge portion 11.

[0028] The rotating support frame includes a rotating crossbar 31 horizontally and rotatably mounted on the frame of the bench press machine, and support rods 32 fixedly mounted on the rotating crossbar 31. The number of support rods 32 matches the number of movable arms 101, specifically two. Each support rod 32 has a support body 33 fixedly mounted on its upper end. The support rods 32 and their support bodies 33 swing back and forth around the long axis of the rotating crossbar 31 between a position avoiding the movable arms 101 of the bench press machine and a support position supporting the movable arms 101. When swinging forward to the support position, the support body 33 corresponds to the movable arms 101 and can be used to support them. Figure 4 As shown, when the arm swings backward to the avoidance position, the support 33 is not on the vertical movement path of the boom 101, as... Figure 5 As shown. The support surface of the support body 33 in the front-to-back direction is long enough to allow the support body 33 to better contact and support the boom 101.

[0029] The two ends of the rotating crossbar 31 are respectively mounted on the frame via seated bearings 34. The two ends of the rotating crossbar 31 are respectively interference-fitted into the inner ring of the seated bearings 34, and the seated bearings 34 are locked and fixed to the frame by bolts. This not only enables the rotating crossbar 31 to rotate around its own axis, but also facilitates the disassembly and assembly of the rotating crossbar 31.

[0030] The rotating crossbar 31 is connected to the second hinge part 12 via a connecting rod 20. The first hinge part 11 is connected to the frame via a first hinge shaft. The second hinge part 12 is connected to the connecting rod 20 via a second hinge shaft. The connecting rod 20 is connected to the rotating crossbar 31 via a third hinge shaft. The foot pedal frame 10 has foot pedals on its left and right front ends away from the connecting rod 20. Stepping on the foot pedals causes the foot pedal frame 10 to rotate downwards with the first hinge part 11 as the fulcrum, while the rear end of the foot pedal frame 10 rotates upwards. When the rear end of the foot pedal frame 10 rotates upwards, the connecting rod 20 drives the rotating crossbar 31 to rotate backwards around its axis. When the rear end of the foot pedal frame 10 rotates downwards, the connecting rod 20 drives the rotating crossbar 31 to rotate forwards around its axis. When the foot pedal frame 10 rotates forwards, it is in the support position.

[0031] The frame includes a support leg located on the front side. The rear end of the foot pedal 10 is hinged to the support leg via a first hinge 11, while the front end of the foot pedal 10 extends forward relative to the support leg. When the support rod 32 is in the avoidance position, the rear end of the foot pedal 10 abuts against the rear side of the support leg, serving as a second limiting structure to keep the support rod 32 in the avoidance position. When the support rod 32 is in the support position, the rear end of the foot pedal 10 abuts against the front side of the support leg, serving as a first limiting structure to keep the support rod 32 in the support position. The foot pedal 10 has a buffer pad 13 at the position where it contacts the frame after rotating around the first hinge 11. When the support rod 32 swings to the support position, the foot pedal 10 contacts the frame through the buffer pad 13, which serves to limit and maintain the angle of the support rod 32. At this time, the support rod 32 swings forward at an acute angle relative to the rotating crossbar 31, such as 5 degrees.

[0032] To facilitate the automatic return of the pedal frame 10 after the foot pedal force is removed and when there is no other external force in the movable support component system, one end of the return member 40 is fixed on the frame and the other end is installed on the connecting rod 20 near the second hinge 12. Specifically, the return member 40 is a gas spring. In this way, the return member 40 acts on the front end of the connecting rod 20 and then on the pedal frame 10, so that the support rod 32 swings away from the pedal frame 10 to the avoidance position.

[0033] 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. Various changes and modifications may be made to this invention without departing from its spirit and scope. All such changes and modifications fall within the scope of this invention as defined by the appended claims and their equivalents.
