Description

Technical Field

[0001] The present invention relates to the technical field of fitness equipment, and particularly relates to a pushing trainer and a training method. Background Art

[0002] Pushing trainers include incline chest press trainers, flat bench press trainers, seated shoulder press trainers, etc. Generally, in terms of structure, a moving arm is hinged on a frame, and resistance is adjusted by adding barbell plates or counterweight plates on the moving arm. A seat board or a lying board is arranged on the frame, and the trainer can achieve the effect of exercising muscles by pushing the moving arm up and down.

[0003] Chinese published patent document (CN214181609U) discloses a lying fitness device with a boosting function. The boosting mechanism is connected to the transmission component through a linkage mechanism. When the user touches the boosting mechanism downward, the transmission component is lifted linearly through the linkage mechanism and the guide sleeve. The lifted transmission component can assist in lifting the adjustable hanging plate moving arm mechanism, and at the same time, the main limit rod with a fixed height on the frame is used to achieve the support and limit when the moving arm mechanism is pressed down. Additionally, Chinese published patent document (CN219090992U) discloses a double-rail incline chest press trainer. The footrest is connected to the support frame through a linkage mechanism, so that the footrest can drive the support frame and the push frame to move upward through the linkage mechanism, and the up and down displacement of the support frame is limited by a sliding sleeve. At the same time, the inclined arm of the frame with a fixed height is used to achieve the support and limit when the push frame is pressed down.

[0004] Both of the above two types of pushing trainers disclose that a boosting mechanism is used to help the trainer push up better at the initial moment of pushing, playing a boosting role. However, firstly, since the boosting support part of the boosting mechanism only moves up and down, the boosting support part is always in the up and down pushing line of the moving arm, which limits the extreme low height of the moving arm and cannot meet the different requirements of different exercisers for the exercise range and intensity. Secondly, since the height of the boosting support part is the starting height of the moving arm, in order to achieve the purpose of exercising muscles, this starting height should not be too high, which results in the starting height being at a height where the exerciser is not very good at exerting force and requires upward boosting. Thirdly, since the support and limit for the downward pressure of the moving arm are both achieved through parts with a fixed height on the frame, the lower limit position of the swing of the moving arm is not adjustable. In this way, for trainers with longer arms, the lower limit of the swing of the moving arm cannot be made lower, and the expected muscle stretching exercise effect cannot be achieved. Summary of the Invention

[0005] The purpose of the present invention is to provide a pushing trainer and a training method, which can enable the trainer to have a suitable starting height for exerting force and a lower limit position suitable for the trainer's own arm length and muscle stretching range during training.

The rotating support frame includes a rotating cross bar horizontally and rotatably mounted on the frame of the push-lift trainer and a support rod fixed on the rotating cross bar. The rotating cross bar is connected to the second hinge portion by a connecting rod. The support rod swings back and forth between an avoidance position for avoiding the movable arm of the push-lift trainer and a supporting position for supporting the movable arm of the push-lift trainer along with the rotating cross bar. The return member acts on the pedal frame or the connecting rod to make the support rod swing to the avoidance position in a direction away from the pedal frame.

[0009] Preferably, a first limiting structure for maintaining the support position is provided between the pedal frame and the frame or between the rotating support frame and the frame.

[0010] Preferably, when the movable support assembly is in the supporting position, the support rod swings forward at an acute angle relative to the rotating cross rod.

[0011] Preferably, the return member is a gas spring.

[0012] Preferably, the lower limit safety support assembly includes a base, a movable plate and a support block, the base is fixedly mounted on the frame, the support block is fixedly mounted on the top of the movable plate, the inclination angle of the movable plate relative to the base is adjustable and the movable plate and the base remain fixed after adjustment, the support height of the support block changes with the inclination angle of the movable plate, and support blocks with different support heights are all on the movement path of the movable arm of the push trainer.

[0013] Preferably, the base is provided with a plurality of groups of slots spaced apart in an upper and lower manner and a transition slot connecting the slots on the same side. The first end of the movable plate is switched and positioned in one group of the slots through the transition slot. The movable plate is positioned in slots at different heights to change the inclination angle of the movable plate and the supporting height of the support block. The second end of the movable plate is against the base.

[0014] Preferably, a clamping column is provided at a position of the first end of the movable plate corresponding to the clamping slot, and the clamping column is clamped in the clamping slot and slidably fitted in the transition slot.

[0015] Preferably, the movable arm is provided with a first support portion cooperating with the lower limit safety support assembly and a second support portion cooperating with the movable support assembly.

[0016] The present invention also provides a training method for a push-up trainer, which comprises adjusting the support height of the lower limit safety support assembly before training and at this time, the movable arm of the push-up trainer is supported by the movable support assembly at a height higher than the highest support height of the lower limit safety support assembly; during training, the movable arm is pushed upward with the support height of the movable support assembly as the starting height, and after being pushed upward, the movable support assembly automatically leaves the up and down movement path of the movable arm, and then is pushed up and down reciprocatingly with the support height of the lower limit safety support assembly as the lower limit position; when pausing or completing training, the movable support assembly is operated to reset to support the movable arm.

[0017] Preferably, during the pause, the support height of the lower limit safety support assembly is adjusted to adjust the lower limit position of the push-up.

[0019] The push-up trainer of the present invention comprises a lower limit safety support assembly and a movable support assembly. The movable support assembly switches between an avoidance position and a support position, and a support height of the movable support assembly in the support position is higher than a maximum support height of the lower limit safety support assembly. The support height of the movable support assembly to the movable arm is set at a suitable height, thereby obtaining a starting height suitable for exerting force. During training, the movable support assembly will switch to the avoidance position to be staggered with the up and down movement path of the movable arm, making it easier for the trainee to exercise below the above-mentioned starting height, without limiting the extreme low position of the exercise range.

[0020] In addition, the present invention also changes the traditional method of fixing the support height of the boom, and proposes an innovative method of adjustable support height of the lower limit safety support assembly, which allows the trainee to adjust the lower limit position of the boom to a comfortable position for his or her arm according to needs for safe exercise, and can also adjust the lower limit position of the boom according to the intensity of exercise to increase the muscle stretching amplitude.

[0021] The training method of the present invention combines the movable support component and the lower limit safety support component to enable the trainee to have a starting height for push-ups that is suitable for exerting force and a lower limit position that is suitable for the trainee's own arm length and muscle stretching amplitude requirements during training. By installing the lower limit support component at the lower limit position, accidents such as accidental loss of the hands and the movable arm pressing on the trainee can be avoided during training.

[0022] The press trainer of the present invention includes but is not limited to a supine chest press trainer, an incline chest press trainer and a seated shoulder press trainer, and the resistance source of the movable arm can be an insert-type counterweight block or a hanging-type counterweight block or a servo force.

Detailed Description of the Invention

[0033] In order to make the above features and advantages of the present invention more obvious and understandable, specific embodiments are hereinafter given and described in detail in conjunction with the accompanying drawings.

[0034] As Figures 1-8As shown, this embodiment provides a supine press trainer, including a frame, a lying board assembly mounted on the frame, a movable arm 101 hinged on the frame, and a lower limit safety support assembly and a movable support assembly. The movable arm 101 is provided with two groups and is respectively hingedly arranged at the rear end of the frame, and the front ends of the two groups of movable arms 101 extend to both sides of the rear part of the lying board assembly respectively. Barbell plates of appropriate weight are hung on the movable arms 101, and the trainee lies on the lying board assembly and holds the handles on the movable arms 101 with both hands to exercise up and down. Please note that the press trainer of the present invention is not limited to the supine press trainer, and the lying board assembly and the frame are adaptively adjusted according to the trainee's sitting or lying posture during training, such as an incline seated chest press trainer (such as Figure 9 shown) and seated shoulder press, etc.

[0035] In this embodiment, the support rod 34 of the movable support assembly swings back and forth and has a supporting position and an avoidance position. When the movable support assembly is in the supporting position, it can be used to contact the boom 101 to achieve the function of supporting the boom 101. When the movable support assembly is in the avoidance position, it staggers the up and down movement path of the boom 101 to achieve the function of avoiding the boom 101.

[0036] Specifically, the movable support assembly includes a pedal frame 31, a connecting rod 32, a rotating support frame and a return member 36. The frame includes a first supporting foot 102 located at the front side. The rear side of the pedal frame 31 is hinged on the first supporting foot 102 through a first hinged portion so that the pedal frame 31 can rotate up and down with the first hinged portion as a fulcrum. A second hinged portion is provided on the pedal frame 31 below the first hinged portion and located behind the first supporting foot 102. The second hinged portion is used to be movably connected to the front end of the connecting rod 32, so that the pedal frame 31 can be driven to rotate around the first hinged portion through the forward and backward movement of the connecting rod 32. The front side of the pedal frame 31 extends forward relative to the first supporting foot 102 and is connected to pedal rods at the left and right ends of the front side of the pedal frame 31. The pedal rods are convenient for the trainer to step on the pedal frame 31 to apply force to the pedal frame 31 so that the front side of the pedal frame 31 rotates downward around the first hinged portion and the rear side of the pedal frame 31 rotates upward around the first hinged portion.

[0037] The rotating support frame includes a rotating cross bar 33 horizontally and rotatably mounted on the frame of the push-up trainer through a seat bearing 37 and two support bars 34 respectively fixed on the rotating cross bar 33 by bolts or welding. A support element 35 is fixedly mounted on the top of the support bar 34. The support element 35 is made of plastic material, so that the support bar 34 and the support element 35 thereon can swing forward and backward between the avoidance position of avoiding the movable arm 101 and the support position of supporting the movable arm 101 along with the rotating cross bar 33. When swinging forward to the support position, the support element 35 corresponds to the movable arm 101 and can be used to support the movable arm 101, such as Figure 3As shown, when swinging backward to the avoidance position, the support element 35 is not on the up-and-down movement path of the boom 101, as Figure 4 shown. The number of the support rods 34 matches the number of the booms 101, and one support rod 34 corresponds to one boom 101 respectively, which is used to support the boom 101 after pausing or stopping the training. A second support portion 1012 which is matched with the support element 35 of the movable support assembly is arranged on the boom 101; the support surface of the support element 35 in the front-back direction is long enough so that the support element 35 can better contact and support the boom 101.

[0038] The rotating cross bar 33 is connected with the second hinge portion of the pedal frame 31 through a connecting rod 32. One end of the return element 36 is fixedly installed on the frame and the other end is installed at a position of the connecting rod 32 close to the second hinge portion. Specifically, the return element 36 adopts a gas spring, so that the return element 36 acts on the front end of the connecting rod 32 and then acts on the pedal frame 31 to enable the support rod 34 to swing toward a direction away from the pedal frame 31 to the avoidance position.

[0039] When the support rod 34 is in the avoidance position, the rear end of the pedal frame 31 abuts against the rear side of the first support foot 102 to serve as a second limiting structure. When the support rod 34 is in the support position, the rear end of the pedal frame 31 abuts against the front side of the first support foot 102 to serve as a first limiting structure. A first buffer pad is arranged at the position where the pedal frame 31 contacts the frame after rotating around the first hinge portion. A second buffer pad is arranged at the position corresponding to the rear side of the first support foot 102 where the rear side of the pedal frame 31 rotates downward. When the support rod 34 swings to the support position, the pedal frame 31 contacts the frame through the first buffer pad to play a role in limiting and maintaining the angle of the support rod 34. At this time, the support rod 34 swings forward by an acute angle relative to the rotating cross bar 33, and the acute angle is, for example, 5 degrees.

[0040] In this embodiment, the lower limit safety support assembly corresponds to the up-and-down movement path of the boom 101 and its support height is adjustable. The trainer can adjust the lower limit position of the boom 101 by adjusting the support height of the lower limit safety support assembly. The lower the support height of the lower limit safety support assembly is, the lower the lower limit of the boom 101 is. At the positions on the left and right sides of the frame for installing the lower limit safety support assembly, an installation arm 103 which is inclined upward from front to back is respectively arranged. The lower limit safety support assembly is provided with two groups and is respectively fixed on the installation arm 103 by common methods such as bolts or welding. The two movable support assemblies are between the two lower limit safety support assemblies, and the support height of the movable support assembly in the support position is higher than the highest support height of the lower limit safety support assembly.

[0041] Specifically: the lower limit safety support assembly includes a base 21, a movable plate 22 and a support block 23, the base 21 is an L-shaped structure connected by a horizontal seat and a vertical seat, wherein the horizontal seat is fixedly installed on the mounting arm 103 by bolts and is in an inclined state, and the vertical seat is composed of two side panels arranged at intervals, and the two side panels are opposite to each other and are provided with a plurality of groups of slots 211 arranged at intervals up and down and a transition groove 212 connecting the same side of each slot 211, and the space between the two side panels is provided for the movable plate 22 to shift, and the function of the transition groove 212 is to provide a channel for the movable plate 22 to switch between different slots 211.

[0042] The first end of the movable plate 22 is switched and positioned in one of the slots 211 through the transition groove 212. The movable plate 22 is positioned in the slots 211 at different heights to change the tilt angle of the movable plate 22 relative to the horizontal seat. The tilt angle difference is set at 8°-15° according to the number of slots 211 and the height adjustment requirements. The support block 23 is fixedly mounted on the top of the movable plate 22. The support height of the support block 23 changes with the tilt angle of the movable plate 22 and the support blocks 23 of different support heights are all on the motion path of the movable arm 101 of the push trainer. The second end of the movable plate 22 is against the horizontal seat. The movable arm 101 is provided with a first support portion 1011 that matches the support block 23 of the lower limit safety support assembly.

[0043] Slide grooves 213 are horizontally provided at corresponding positions on both sides of the horizontal seat, and a sliding block 222 is provided at a position corresponding to the slide groove 213 at the second end of the movable plate 22, and the sliding block 222 is slidably matched with the slide groove 213. Preferably, the cross-sectional shape of the sliding block 222 is circular, so that the second end of the movable plate 22 can rotate arbitrarily in the slide groove 213. Of course, the sliding block 222 can adopt other cross-sectional shapes under the condition of meeting the angle adjustment requirements of the movable plate 22.

[0044] A clamping column 221 is provided at the position of the first end of the movable plate 22 corresponding to the slot 211. The clamping column 221 is clamped in the slot 211 and slidably fits in the transition slot 212. The opening height of the slot 211 connected to the transition slot 212 is higher than the clamping height of the slot 211 clamped with the clamping column 221. In this way, the movable plate 22 can be displaced in the transition slot 212 and the movable plate 22 and the base 21 can be kept fixed after adjustment by clamping. The height adjustment of the support block 23 can be achieved by simply pulling out the movable plate 22 and switching to different slot 211 positions. It is simple and fast, and the trainee can adjust it by himself without getting up. Figure 5 and Figure 6 The first end of the movable plate 22 is connected to an operating rod 24 , and the movable plate 22 is adjusted by the operating rod 24 .

[0045] The training method of the push-up trainer of this embodiment is as follows: before training, the support height of the lower limit safety support assembly is adjusted and at this time, the movable arm 101 of the push-up trainer is supported by the movable support assembly at a height higher than the highest support height of the lower limit safety support assembly; during training, the movable arm 101 is pushed upward with the support height of the movable support assembly as the starting height, and after the upward push, the movable support assembly automatically leaves the up-and-down movement path of the movable arm 101, and then the movable arm 101 is pushed up and down reciprocatingly with the support height of the lower limit safety support assembly as the lower limit position; when pausing or completing training, the movable support assembly is operated to reset to support the movable arm 101. During the pause interval, the support height of the lower limit safety support assembly is adjusted, thereby adjusting the lower limit position of the push-up.

[0046] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for illustrating the principles of the present invention.
