Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and more specifically, to an ergonomic seated push-up training device. Background Technology

[0002] The seated push-up machine is a fitness device based on a seated posture, specifically designed to train pushing muscles. Its core function is to specifically strengthen the muscles in the upper body that actively push away objects through controlled force movements. At the same time, the machine structure ensures training safety and improves the accuracy of movements. It is a common strength training tool in gyms and home fitness.

[0003] A search revealed that Chinese patent CN220860580U discloses a seated forward push trainer that uses leverage to adjust the pushing force, thereby increasing its versatility. When using the seated forward push trainer, the user sits steadily on the seat with their back against the backrest, grips the armrests on both sides, and pushes forward smoothly until reaching the limit of their arm position, keeping their elbows slightly bent throughout. They pause briefly, then slowly bend their elbows to return to the starting position. This repeated motion aims to exercise the chest and shoulder muscles.

[0004] When using the above-mentioned training device, the user grips the handles on both sides with both hands and pushes forward smoothly. However, the handles and the triangular upper arm are fixedly connected, making it inconvenient to adjust the distance between the handles on both sides. Since different users have different shoulder widths, those with narrower shoulder widths need to excessively abduct their shoulder joints to grip the handles, which causes the rotator cuff muscles to be continuously stretched. This can easily lead to shoulder pain during training, and long-term use may cause rotator cuff injury. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an ergonomic seated push training device, which aims to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an ergonomic seated push training device, comprising a base, a connecting frame, and an ergonomic chair body. The connecting frame is fixedly installed at the top center of the base, and the top of the connecting frame is fixedly connected to the ergonomic chair body. A support frame is fixedly connected inside the connecting frame. An adjustment component is provided between the support frame and the connecting frame. The adjustment component includes a positive and negative lead screw, two sliding plates, two side plates, multiple fixing bolts, a bevel gear set, a self-locking motor, and multiple limiting plates. The outer side of the positive and negative lead screw is movably connected to the support frame through two bearings. Both sliding plates are threadedly connected to the positive and negative lead screw, and the opposite sides of the two sliding plates pass through both sides of the connecting frame and are fixedly connected to the two side plates. Each of the opposite sides of the two side plates is provided with a stand, and the two stands are fixed to the two side plates by multiple fixing bolts.

[0007] Furthermore, the plurality of limiting plates are respectively fixedly installed at the top and bottom of the two sliding plates.

[0008] As can be seen, in the above technical solution, multiple limiting plates can limit the movement distance of the two slides and prevent the slides from leaving the thread range of the positive and negative screws.

[0009] Furthermore, the self-locking motor is fixedly installed at the top of the support frame, and the self-locking motor is connected to the positive and negative lead screws through a bevel gear set.

[0010] Furthermore, each of the two uprights is fixedly connected to a movable wheel near its four corners at the bottom, and the bottom of each movable wheel is in contact with the base.

[0011] As can be seen, in the above technical solution, the upright frame drives multiple moving wheels to slide on the top of the base, thereby improving the stability of the upright frame.

[0012] Furthermore, both of the uprights are equipped with training components, each of which includes a triangular upper arm, a hinge, a handrail, a buffer pad, multiple lead screws, multiple counterweights, and multiple threaded pressure sleeves.

[0013] Furthermore, the two triangular upper arms are connected to the two uprights via two hinges, the opposite ends of the two handrails are fixedly connected to the two triangular upper arms, and the tops of the two buffer pads are fixedly connected to the two triangular upper arms.

[0014] Furthermore, the bottom ends of the plurality of lead screws are respectively fixedly connected to two triangular upper arms, and the plurality of counterweights and the plurality of threaded sleeves are respectively movably sleeved on the plurality of lead screws.

[0015] As can be seen, in the above technical solution, the weight of the triangular upper arm can be increased as needed.

[0016] The technical effects and advantages of this utility model are as follows: 1. This utility model provides users with a stable and comfortable basic posture through the ergonomic chair body. The self-locking motor can drive the positive and negative lead screws to rotate through the bevel gear set. The positive and negative lead screws can drive the two slides and two side plates to move in opposite directions, thereby driving the two uprights and two training components to move in opposite directions. The distance between the two training components can be adjusted according to the needs. The operation is simple and convenient to adjust the distance between the training components on both sides. It has a wide range of applications. 2. This utility model allows you to grip the two handrails with both hands and push them forward smoothly.

[0020] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] Refer to the instruction manual appendix Figure 1-5 The ergonomic seated training device of this embodiment includes a base 1, a connecting frame 2, and an ergonomic chair body 3. The connecting frame 2 is fixedly installed at the top center of the base 1, and the top of the connecting frame 2 is fixedly connected to the ergonomic chair body 3. A support frame 4 is fixedly connected inside the connecting frame 2. An adjustment component 5 is provided between the support frame 4 and the connecting frame 2. The adjustment component 5 includes a positive and negative lead screw 501, two sliding plates 502, two side plates 503, multiple fixing bolts 504, a bevel gear set 505, a self-locking motor 506, and multiple limiting plates 507. The outer side of the positive and negative lead screw 501 is movably connected to the support frame 4 through two bearings. The two sliding plates 502 are threadedly connected to the positive and negative lead screw 501, and the opposite sides of the two sliding plates 502 pass through both sides of the connecting frame 2 and are fixedly connected to the two side plates 503. A stand 6 is provided on the opposite side of the two side plates 503, and the two stand 6 are fixed to the two side plates 503 through multiple fixing bolts 504.

[0022] Furthermore, multiple limiting plates 507 are fixedly installed at the top and bottom of the two sliding plates 502 respectively, and a self-locking motor 506 is fixedly installed at the top of the support frame 4. The self-locking motor 506 is connected to the positive and negative lead screws 501 through a bevel gear set 505. The bottom of the two uprights 6 is fixedly connected to the four corners, and the bottom of the multiple moving wheels 7 is in contact with the base 1.

[0023] Furthermore, each of the two uprights 6 is equipped with a training component 8. Each training component 8 includes a triangular upper arm 801, a hinge seat 802, a handrail 803, a buffer pad 804, multiple lead screws 805, multiple counterweights 806, and multiple threaded sleeves 807. The two triangular upper arms 801 are connected to the two uprights 6 through two hinge seats 802 respectively. The opposite ends of the two handrails 803 are fixedly connected to the two triangular upper arms 801 respectively. The tops of the two buffer pads 804 are fixedly connected to the two triangular upper arms 801 respectively. The bottom ends of the multiple lead screws 805 are fixedly connected to the two triangular upper arms 801 respectively. The multiple counterweights 806 and multiple threaded sleeves 807 are movably sleeved on the multiple lead screws 805 respectively.

[0024] The user grips the two handrails 803 firmly and pushes forward smoothly. Since the triangular upper arm 801 and the upright 6 are connected by a hinge 802, the two handrails 803 can drive the two triangular upper arms 801 to deflect upward. When the hands return to the initial position, the buffer pad 804 can cushion the triangular upper arm 801 to prevent it from rigidly contacting the upright 6. Different numbers of counterweights 806 are respectively fitted onto multiple screws 805 as needed. Then, multiple threaded sleeves 807 are rotated in sequence, and the multiple threaded sleeves 807 fix the multiple counterweights 806 to the triangular upper arm 801. The weight of the triangular upper arm 801 can be increased as needed. The structure is simple and easy to use.

[0025] The usage method of this embodiment is as follows: When in use, the user sits on the ergonomic chair body 3, which provides a stable and comfortable basic posture for the user. The self-locking motor 506 is started. Since the bevel gear set 505 includes two bevel gears, and the two bevel gears are fixedly connected to the output shaft of the self-locking motor 506 and the positive and negative screw 501 respectively, the self-locking motor 506 can drive the positive and negative screw 501 to rotate through the bevel gear set 505. Since the two slide plates 502 are threadedly connected to the positive and negative screw 501, and the connecting frame 2 restricts the rotation of the two slide plates 502, the positive and negative screw 501 can drive the two slide plates 502 and the two side plates 503 to move in opposite directions. The multiple limiting plates 507 can limit the movement distance of the two slide plates 502 and prevent the slide plates 502 from leaving the thread range of the positive and negative screw 501. This allows the two uprights 6 and the two training components 8 to move in opposite directions. The distance between the two training components 8 can be adjusted as needed. The fixing between the side plate 503 and the uprights 6 can be released by multiple fixing bolts 504, allowing the uprights 6 and the training components 8 to be disassembled and replaced. The operation is simple and convenient, and the distance between the two training components 8 can be adjusted. It has a wide range of applications. At the same time, the uprights 6 drive multiple moving wheels 7 to slide on the top of the base 1, thereby improving the stability of the uprights 6.
