Description

TECHNICAL FIELD

[0001] The present application belongs to the technical field of fitness equipment, and particularly relates to a multi-angle chest training device. BACKGROUND

[0002] The chest training device is a strength training equipment for exercising the upper chest muscle group, the middle chest muscle group, the lower chest muscle group and other upper limb muscle groups.

[0003] The chest training device in the prior art comprises a base frame, a seat, two handle frames and a resistance source. The seat is fixed to the base frame. The two handle frames are oppositely arranged on the two sides of the seat and are rotationally connected to the base frame. The resistance source is connected to the two handle frames to provide training resistance. A user sits on the seat and pushes the two handle frames to perform chest push training.

[0004] However, the chest training device in the prior art has a single function. Each chest training device can usually only support chest push training in a fixed direction. If it is necessary to switch from chest upper muscle group training to chest lower muscle group training, another chest training device needs to be used for training, resulting in high training cost. SUMMARY

[0005] The present application at least partly solves one of the problems in the related art.

[0006] Therefore, the present application aims to provide a multi-angle chest training device. The handle frame assembly is driven by the adjusting module to rotate around the seat assembly, so as to change the pushing direction of the handle frame assembly when used for chest training. Thus, different chest muscle groups of a user can be stimulated. Only one multi-angle chest training device can meet the training needs of a user in multiple different types of chest training, thereby reducing the training cost.

[0007] The present application provides a multi-angle chest training device, comprising: a base frame assembly; a seat assembly arranged on the base frame assembly; a handle frame assembly rotationally arranged on the two sides of the seat assembly. The handle frame assembly is pushed to rotate to perform chest training; an adjusting module arranged between the seat assembly and the handle frame assembly and rotationally connected to both. The adjusting module is used to rotate or stop rotating the handle frame assembly around the seat assembly, so as to change the pushing direction of the handle frame assembly when used for chest training.

[0008] Existing chest trainers are limited in function, with each trainer typically supporting only one fixed direction of chest push-up training. If it is necessary to switch from training one part of the chest muscles to another, such as from training the upper chest muscles to training the lower chest muscles, a separate chest trainer is required, resulting in excessively high training costs.

[0009] To address the aforementioned technical problems, this application proposes an adjustment module that drives the handle frame assembly to rotate around the seat assembly, thereby changing the direction of the push force when the handle frame assembly is used for chest training. This allows for stimulation of different chest muscle groups in the user, enabling a single multi-angle chest trainer to meet various types of chest training needs and reducing training costs, thus solving the technical problems in the prior art.

[0010] In some embodiments, the adjustment module rotates relative to the seat assembly about a first pivot axis, and the handlebar assembly rotates relative to the adjustment module about a second pivot axis, wherein the extension lines of the first pivot axis and the extension lines of the second pivot axis are perpendicular to each other.

[0011] Based on the above technical solution, by setting the extension lines of the first and second axes of rotation to be perpendicular to each other, the movements around the first and second axes of rotation are ensured to be independent of each other, and the adjustment of the included angle can maximize the influence on the execution of chest training movements, thereby improving the adjustment efficiency of chest training movements.

[0012] In some embodiments, the adjustment module includes: A rotating frame is rotatably mounted on the seat assembly, and the handle frame assembly is rotatably mounted on the rotating frame; A locking component is provided on the rotating frame, the locking component being used to release or lock the relative rotation between the rotating frame and the seat assembly.

[0013] Based on the above technical solution, the rotating frame allows users to quickly adjust the direction of thrust according to different types of chest training. At the same time, the locking component provides stable control over the rotating frame, effectively preventing movement risks caused by deviation during chest training, and improving the safety and reliability of the multi-angle chest trainer of this application during use.

[0014] In some embodiments, the locking component includes: The seat assembly and / or the base frame assembly are provided with multiple limiting holes; A pin is slidably inserted into the rotating frame; Adjust the handle to rotate the pin that is mounted on the rotating frame and connected to it; The adjustment handle rotates relative to the rotating frame to drive the pin to extend into or out of the limiting hole, thereby locking or releasing the relative rotation between the rotating frame and the seat assembly.

[0015] Based on the above technical solution, by setting multiple limiting holes and using pins, the rotating frame can be quickly and accurately positioned. The locking method using pins has high shear resistance, ensuring that the rotating frame will not deviate in rotation angle due to external force during chest training. The design of the adjustment handle makes it easy for users to control the movement of the pins with one hand, improving the control efficiency of the pins.

[0016] In some embodiments, the multi-angle chest trainer further includes: A reset member is disposed between the pin and the rotating frame and connected to both respectively. The reset member is used to keep the pin inserted into the limiting hole so as to elastically lock the relative rotation between the rotating frame and the seat assembly.

[0017] Based on the above technical solution, by setting a reset component, the pin can automatically return to the locked state after adjustment, avoiding the need for the user to manually adjust the pin to extend into the limiting hole, reducing adjustment steps, and preventing the rotating frame from becoming loose due to the user's negligence in not re-inserting the pin.

[0018] In some embodiments, the multi-angle chest trainer further includes: An arc-shaped positioning member has one end disposed on the seat assembly and / or the base frame assembly, and the other end extends and bends around the rotational connection between the rotating frame and the seat assembly, with a plurality of limiting holes passing through it along the extension direction of the arc-shaped positioning member.

[0019] Based on the above technical solution, by setting an arc-shaped positioning component, it is convenient to lock the seat assembly and / or base frame assembly with a pin component. At the same time, the position of the limiting hole is more regular and matches the rotation trajectory of the rotating frame, which helps to accurately set multiple angle positions of the rotating frame and improve the adjustment accuracy of the rotating frame.

[0020] In some embodiments, the multi-angle chest trainer further includes: A fixed handle is mounted on the rotating frame and rotatably connected to the adjusting handle; A connector is provided between the adjusting handle and the pin and is connected to both respectively.

[0021] Based on the above technical solution, by setting a fixed handle and connecting parts to cooperate with the adjustment handle to control the movement of the pin, the control efficiency and operation feel of the pin are improved. The fixed handle provides the user with a clear grip point, avoiding misoperation or slippage of the adjustment handle during the adjustment process.

[0022] In some embodiments, the rotating frame includes: The rotating part, wherein one end of the rotating part is rotatably disposed on both sides of the seat assembly, and the other end extends away from the seat assembly; The mounting part has two ends connected to the extension ends of the two rotating parts respectively. The locking component and the handle bracket component are mounted on the mounting part and rotate relative to the seat component based on the rotating part.

[0023] Based on the above technical solution, by adopting a spatial frame structure composed of two rotating parts and a mounting part, the overall load-bearing capacity and deformation resistance of the rotating frame are improved, good rotational stability is ensured, and the structural stress concentration problem caused by single-point support is effectively reduced.

[0024] In some embodiments, the adjustment module further includes: A support assembly is disposed between the rotating frame and the base frame assembly and connected to both respectively. The support assembly is used to stop the rotating frame at the preset position when the rotating frame rotates to the preset position.

[0025] Based on the above technical solution, the support component provides additional positioning and stopping functions for the rotating frame, preventing excessive rotation of the rotating frame due to user misoperation and ensuring safety during use.

[0026] In some embodiments, the multi-angle chest trainer further includes: A resistance frame is provided on the handle frame assembly, and the resistance frame is used to attach and detach counterweights to adjust the resistance of the handle frame assembly during chest training. A buffer pad is disposed between the resistance frame and the adjustment module.

[0027] Based on the above technical solution, by setting up a resistance frame, users can flexibly adjust the movement resistance of the handle frame assembly according to their personal training plan. The cushioning pad can effectively reduce the impact of the resistance frame on the adjustment module when it moves with the handle frame assembly.

[0028] In summary, this application provides a multi-angle chest trainer. An adjustment module drives the handle frame assembly to rotate around the seat assembly. Essentially, an adjustable hub with increased degrees of freedom is placed between the seat assembly and the handle frame assembly, allowing the pivot point of the handle frame assembly to rotate to different positions relative to the seat assembly. This changes the direction of the push force when the user uses the handle frame assembly for chest training. Based on the switching of the push force direction, users can perform various chest exercises targeting the upper, middle, and lower chest muscles, as well as other upper limb muscle groups. A single multi-angle chest trainer can meet the diverse chest training needs of users, reducing training costs.

Figure 1 To be continued Figure 7 Specific embodiments are described below.

[0037] Reference Appendix Figures 1 to 7 This application provides a multi-angle chest trainer, including a base frame assembly 100, a seat assembly 200, a handle frame assembly 300, and an adjustment module.

[0038] The seat assembly 200 is mounted on the base frame assembly 100; the two handlebar assemblies 300 are rotatably mounted on both sides of the seat assembly 200, and chest training is performed by pushing the two handlebar assemblies 300 to rotate; the adjustment module is located between the seat assembly 200 and the handlebar assemblies 300 and is rotatably connected to both of them. The adjustment module is used to make the handlebar assemblies 300 rotate around the seat assembly 200 or stop rotating, so as to change the direction of the pushing force of the handlebar assemblies 300 when used for chest training.

[0039] Specifically, the base frame assembly 100 is mounted on a bearing plane and serves as the mounting base for other components of the multi-angle chest trainer; the seat assembly 200 is mounted on the base frame assembly 100 and is used to provide support for the user's torso.

[0040] The handle assembly 300 further includes a swing frame 301 and a grip handle 302. One end of the two swing frames 301 is rotatably mounted on both sides of the seat assembly 200 via an adjustment module, and the other end is provided with two grip handles 302 for the user to grip and exert force. The user sits on the seat assembly 200 and pushes the two swing frames 301 relative to the seat assembly 200 with both arms to rotate them for chest training.

[0041] The existing chest trainers have limited functionality, typically supporting only one fixed direction of chest push training. If it is necessary to switch from training one part of the chest muscles to another, such as from training the upper chest muscles to training the lower chest muscles, a separate chest trainer is required, resulting in high training costs.

[0042] The adjustment module of this application connects the seat assembly 200 and the handlebar assembly 300 by rotation. In essence, it sets an adjustable hub between the seat assembly 200 and the handlebar assembly 300 to increase the degree of freedom, so that the pivot point of the handlebar assembly 300 can be rotated to different positions relative to the seat assembly 200, thereby changing the direction of the push force when the user uses the handlebar assembly 300 for chest training.

[0043] Reference Appendix Figures 5 to 7 In this case, the rotating frame 400 rotates relative to the seat assembly 200 to Figure 5 The multi-angle chest trainer is used to train the lower chest muscles; the rotating frame rotates 400 degrees relative to the seat assembly 200 degrees. Figure 6 The multi-angle chest trainer is used to train the pectoral muscles; the rotating frame rotates 400 degrees relative to the seat assembly 200 degrees. Figure 5 The multi-angle chest trainer is designed to train the upper chest muscles. The rotating frame 400 allows for switching of the thrust direction during training, enabling users to perform various chest exercises targeting the upper, middle, and lower chest muscles, as well as other upper limb muscles.

[0044] Before chest press training, the initial position of the handle frame assembly 300 on one side of the seat assembly 200 can be adjusted by the adjustment module to change the angle of force exerted by the user when pressing the handle frame assembly 300 during chest training, thereby training different parts of the pectoral muscles. In other words, this multi-angle chest trainer can meet the user's various types of chest training needs with just one device, solving the technical problem of excessively high training costs in existing technologies.

[0045] It should be noted that the adjustment module rotates relative to the seat assembly 200 around the first pivot, and the handlebar assembly 300 rotates relative to the adjustment module around the second pivot. The extension lines of the first pivot and the second pivot are neither parallel nor coincident, so as to ensure that when the adjustment module rotates relative to the seat assembly 200 around the first pivot, the position of the second pivot will change relative to the seat assembly 200, thereby changing the direction of the pushing force when the user uses the handlebar assembly 300 for chest training.

[0046] Reference Appendix Figure 2 In some implementations, the adjustment module rotates relative to the seat assembly 200 around a first pivot, and the handlebar assembly 300 rotates relative to the adjustment module around a second pivot, with the extension lines of the first and second pivots perpendicular to each other.

[0047] Specifically, based on the user sitting or lying on the seat assembly 200, the relative position of the user's torso and the bearing plane is fixed. The rotation of the adjustment module around the first axis relative to the seat assembly 200 is used to change the angle between the direction of the thrust and the bearing plane, thereby changing the chest training movement to be biased towards stimulating the upper, middle, and lower pectoral muscles.

[0048] Chest training involves using a machine to press the chest muscles together. As the user pushes the handle assembly 300, their arms move the handle assembly 300 along an arc towards the center, squeezing and stretching the pectoral muscles. The rotation trajectory of the handle assembly 300 around the second axis is the movement trajectory during chest training.

[0049] When the adjustment module changes the angle between the thrust direction and the bearing plane around the first axis, the spatial orientation and position of the second axis will change synchronously; when the user grips the handle frame assembly 300 for training, the initial force direction and the movement trajectory of the handle frame assembly 300 change, thereby stimulating different parts of the pectoral muscles.

[0050] The dual-axis setup of the first and second axes enhances the mechanical stability and reliability of the multi-angle chest trainer of this application, helps to achieve precise switching of thrust direction, and avoids mechanical failure caused by axis interference or synchronization error during training.

[0051] By setting the extension lines of the first and second axes of rotation to be perpendicular to each other, the movements around the first and second axes of rotation are ensured to be independent of each other, and the adjustment of the included angle can maximize the influence on the execution of chest training movements, thereby improving the efficiency of adjusting chest training movements.

[0052] Reference Appendix Figure 1 and Figure 2 In some implementations, the adjustment module includes a rotating frame 400 and a locking assembly 500. The rotating frame 400 is rotatably mounted on the seat assembly 200, and the handle frame assembly 300 is rotatably mounted on the rotating frame 400. The locking assembly 500 is mounted on the rotating frame 400 and is used to release or lock the relative rotation between the rotating frame 400 and the seat assembly 200.

[0053] Specifically, the rotating frame 400 serves as the mechanical basis for connecting the handle frame assembly 300 and the seat assembly 200. By rotating the seat assembly 200 and the handle frame assembly 300 respectively, spatial adjustment for multi-angle chest training can be achieved.

[0054] The rotating frame 400 is rotatably mounted on the seat assembly 200 based on the first rotating shaft, thereby enabling the rotating frame 400 to rotate relative to the seat assembly 200; furthermore, the handlebar assembly 300 is mounted on the rotating frame 400 based on the second rotating shaft, thereby enabling the handlebar assembly 300 to rotate relative to the rotating frame 400.

[0055] The user can rotate the handle frame assembly 300 around the seat assembly 200 by rotating the frame 400, that is, the second axis rotates around the first axis. Thus, when pushing the handle frame assembly 300 around the second axis for chest training, the direction of the pushing force changes to switch between different types of chest training.

[0056] The locking component 500 is disposed on the rotating frame 400. The locking component 500 is used to release or lock the relative rotation between the rotating frame 400 and the seat assembly 200. In essence, it controls the relative rotation state between the rotating frame 400 and the seat assembly 200, thereby adjusting the relative position of the rotating frame 400 and the seat assembly 200 before training.

[0057] The locking component 500 includes, but is not limited to, mechanical bolt locks, rotary ratchet locks, or spring-damped locking structures, and can be selected manually or semi-automatically to control locking or releasing depending on the usage scenario.

[0058] Before chest training, the relative rotation between the rotating frame 400 and the seat assembly 200 is released by the locking component 500. The user can push the rotating frame 400 to rotate relative to the seat assembly 200 to switch between different types of chest training. After the rotating frame 400 rotates relative to the seat assembly 200 to the preset position, the relative rotation between the rotating frame 400 and the seat assembly 200 is locked by the locking component 500, thereby preventing the relative position of the rotating frame 400 and the seat assembly 200 from shifting during chest training, ensuring the stability and safety of chest training.

[0059] It should be noted that the chest muscles stimulated during chest training differ depending on the position of the rotating frame 400 relative to the seat assembly 200. The preset position refers to the locked position of the rotating frame 400 relative to the seat assembly 200 after rotation, corresponding to the target muscle group that the user wants to stimulate. In other words, the preset position should be set according to the actual situation.

[0060] By setting up the rotating frame 400, users can quickly adjust the direction of the thrust according to different types of chest training. At the same time, the locking component 500 provides stable control over the rotating frame 400, effectively preventing movement risks caused by deviation during chest training, and improving the safety and reliability of the multi-angle chest trainer of this application during use.

[0061] Reference Appendix Figure 2 In some embodiments, the rotating frame 400 includes two rotating parts 401 and a mounting part 402. One end of the two rotating parts 401 is rotatably disposed on both sides of the seat assembly 200, and the other end extends away from the seat assembly 200. The two ends of the mounting part 402 are respectively connected to the extended ends of the two rotating parts 401. The locking component 500 and the handle frame component 300 are disposed on the mounting part 402 and rotate relative to the seat assembly 200 based on the rotating parts 401.

[0062] Specifically, the rotating part 401 is a round tube structure or a rectangular tube structure with reinforcing ribs to enhance the rigidity of the rotating part 401; the connection between the rotating part 401 and the seat assembly 200 includes, but is not limited to, the use of bearing seats or universal joint seats; the mounting part 402 includes, but is not limited to, an arc-shaped, U-shaped or telescopic structure to drive the handle frame assembly 300 relative to the seat assembly 200 to adjust the rotation radius.

[0063] Two rotating parts 401 are respectively installed on both sides of the seat assembly 200 to rotate around the same first axis, forming a symmetrical structure and improving rotational stability; the other end of the two rotating parts 401 away from the seat assembly 200 extends outward and is fixedly connected to the mounting part 402 between the two rotating parts 401 to form a stable spatial frame structure. The spatial frame structure is used to avoid the seat assembly 200 from interfering with the rotation of the rotating frame 400.

[0064] The mounting part 402 is provided with a locking component 500 for controlling the rotation state of the entire rotating frame 400 relative to the seat assembly 200; the two swing frames 301 of the handle frame assembly 300 are mounted on the mounting part 402 to achieve rotation relative to the rotating frame 400.

[0065] Based on the cooperation between the two rotating parts 401 and the mounting part 402, the setting positions of the locking component 500 and the handle frame component 300 are expanded, allowing both to rotate relative to the seat component 200 with the rotating frame 400, and ensuring that the functions of the two components on the mounting part 402 do not interfere with each other.

[0066] By employing a spatial frame structure composed of two rotating parts 401 and a mounting part 402, the overall load-bearing capacity and deformation resistance of the rotating frame 400 are improved, ensuring good rotational stability and effectively reducing the structural stress concentration problem caused by single-point support. In addition, the handle frame assembly 300 expands the degree of freedom of movement of the handle frame assembly 300 through the dual linkage connection of the rotating parts 401 and the mounting part 402, which helps to accurately match the different training needs of users and significantly improve the functionality and adaptability of the multi-angle chest trainer.

[0067] Reference Appendix Figure 2 In some embodiments, the seat assembly 200 and / or the base frame assembly 100 are provided with multiple limiting holes, and the locking assembly 500 includes a pin 501 and an adjusting handle 502. The pin 501 is slidably disposed on the rotating frame 400; the adjusting handle 502 is rotatably disposed on the rotating frame 400 and connected to the pin 501; the adjusting handle 502 rotates relative to the rotating frame 400 to drive the pin 501 to extend into or out of the limiting hole, thereby locking or releasing the relative rotation between the rotating frame 400 and the seat assembly 200.

[0068] Specifically, multiple limiting holes are evenly distributed around the first rotating shaft on the seat assembly 200 and / or the base frame assembly 100, with the first rotating shaft as the axis, to match multiple preset angles of rotation of the rotating frame 400 relative to the seat assembly 200.

[0069] When the user needs to adjust the direction of the thrust, the user rotates the adjustment handle 502 relative to the rotating frame 400, thereby causing the pin 501 that is rotatably connected to the adjustment handle 502 to move along its sliding direction, so that the pin 501 extends out of the limiting hole, and the relative rotation between the rotating frame 400 and the seat assembly 200 is released. At this time, the relative rotation position between the rotating frame 400 and the seat assembly 200 can be adjusted. When the rotating frame 400 rotates to the preset position, the user drives the adjustment handle 502 to rotate relative to the rotating frame 400, thereby causing the pin 501 connected to the adjustment handle 502 to move along its sliding direction, so that the pin 501 extends into the limiting hole, and the relative rotation of the rotating frame 400 and the seat assembly 200 is locked. At this time, the relative position of the rotating frame 400 and the seat assembly 200 is fixed.

[0070] By incorporating multiple limiting holes and locking pins 501, the rotating frame 400 can be quickly and accurately positioned, allowing users to flexibly switch the relative rotation angle between the rotating frame 400 and the seat assembly 200 according to their training goals. The pin-type locking mechanism offers high shear resistance, ensuring that the rotating frame 400 will not deviate from its rotation angle due to external forces during chest training, thus improving the safety and durability of the multi-angle chest trainer. Simultaneously, the design of the adjustment handle 502 allows users to control the movement of the locking pin 501 with one hand, enhancing control efficiency.

[0071] In some embodiments, a reset member is disposed between the pin 501 and the rotating frame 400 and connected to both respectively. The reset member is used to keep the pin 501 in the state of extending into the limiting hole, so as to elastically lock the relative rotation between the rotating frame 400 and the seat assembly 200.

[0072] Specifically, reset components include, but are not limited to, wire compression springs, gas springs, rubber spring pads, and electromagnetic reset devices. The specific reset components should be designed according to different elasticity requirements and manufacturing costs.

[0073] The reset component is located between the pin 501 and the rotating frame 400. The reset component is used to ensure that the pin 501 is always in the extended state and inserted into the limiting hole when there is no external force, thereby achieving automatic locking.

[0074] When the user needs to adjust the rotation position of the rotating frame 400 relative to the seat assembly 200, the adjustment handle 502 drives the pin 501 to extend out of the limiting hole. The steel wire spring is compressed as a reset element to store elastic potential energy. After the pin 501 disengages from the limiting hole, the rotation adjustment between the rotating frame 400 and the seat assembly 200 can be carried out.

[0075] When the rotating frame 400 rotates to the preset position, the user releases the adjustment handle 502 to release the elastic potential energy of the reset component. Under the action of elasticity, the reset component automatically pushes the pin 501 back into the corresponding limit hole, realizing automatic positioning and locking.

[0076] By setting a reset component, the pin 501 can automatically return to the locked state after adjustment, avoiding the need for the user to manually adjust the pin 501 to insert into the limiting hole, reducing adjustment steps, and preventing the rotating frame 400 from becoming loose due to the user's negligence in not reinserting the pin 501. This ensures the stability of the rotating frame 400 position during training and greatly improves the convenience and safety of locking with the pin 501.

[0077] Reference Appendix Figure 2 In some embodiments, the arc-shaped positioning member 600 has one end disposed on the seat assembly 200 and / or the base frame assembly 100, and the other end extends and bends around the rotational connection between the rotating frame 400 and the seat assembly 200, and is provided with a plurality of limiting holes along the extension direction of the arc-shaped positioning member 600.

[0078] Specifically, the arc-shaped positioning component 600 can be made of various materials such as stainless steel, aluminum alloy, and engineering plastics, and the choice should be made according to the strength requirements and manufacturing costs. The length and arc angle of the arc-shaped positioning component 600 should be adjusted as needed to achieve a wider or more precise control of the rotation angle of the rotating frame 400.

[0079] The shape of the limiting hole includes, but is not limited to, a circular, trapezoidal, elliptical, or toothed notch structure, in order to improve its alignment accuracy with the pin 501.

[0080] By setting the arc-shaped positioning component 600 as the carrier of the limiting hole, the arc-shaped positioning component 600 and the pin component 501 cooperate to form a track system for multi-angle adjustment and positioning of the rotating frame 400.

[0081] One end of the arc-shaped positioning component 600 is fixed to the seat assembly 200 or the base frame assembly 100, and the other end bends outward with the rotation center of the rotating frame 400 as the center to form an arc-shaped structure, that is, an arc-shaped structure with the first rotating shaft as the axis, corresponding to the rotating frame 400 rotating around the seat assembly 200 based on the first rotating shaft; multiple limiting holes are provided on the arc-shaped positioning component 600 along its arc-shaped extension path, which are used to cooperate with the pin component 501 to achieve precise locking of the rotating frame 400 at multiple angular positions.

[0082] By setting the arc-shaped positioning component 600, it is easy to lock the seat assembly 200 and / or the base frame assembly 100 with the pin component 501. At the same time, it makes the position of the limiting hole more regular and fits the rotation trajectory of the rotating frame 400, which helps to accurately set multiple angle positions of the rotating frame 400 and improve the adjustment accuracy of the rotating frame 400.

[0083] Reference Appendix Figure 2In some embodiments, the multi-angle chest trainer also includes a fixed handle 700 and a connector 800. The fixed handle 700 is disposed on the rotating frame 400 and rotatably connected to the adjusting handle 502; the connector 800 is disposed between the adjusting handle 502 and the pin 501 and is connected to both respectively.

[0084] Specifically, the fixed handle 700 is fixed on the rotating frame 400, and the relative position of the fixed handle 700 and the rotating frame 400 remains unchanged; the fixed handle 700 is provided with a non-slip rubber sleeve, plastic injection molding or aluminum alloy parts to improve grip comfort and durability.

[0085] The adjustment handle 502 is rotatably mounted on the fixed handle 700. The fixed handle 700 provides a fixed gripping position for the user to adjust the rotating frame 400, and can work with the adjustment handle 502 to easily control the movement of the pin 501. The user can precisely control the adjustment handle 502 with the support provided by the fixed handle 700.

[0086] The connector 800 serves as the central connection between the adjustment handle 502 and the pin 501. The connector 800 includes, but is not limited to, a connecting rod, a pull rod, and a chain.

[0087] The two ends of the connector 800 are rotatably connected to the adjusting handle 502 and the pin 501, respectively, to improve the relative flexibility between the adjusting handle 502 and the pin 501, and to ensure that the force on the adjusting handle 502 can effectively drive the pin 501 and avoid mechanical locking.

[0088] Preferably, the fixed handle 700 is fixed on the rotating frame 400, and the adjustable handle 502 is rotatably connected to the fixed handle 700 at any position between its two ends. One end of the adjustable handle 502 is rotatably connected to the pin 501 through the connector 800, and the other end is matched with the fixed handle 700 for the user to grip.

[0089] When the user grasps the end of the adjustment handle 502 away from the connector 800 so that it rotates relative to the fixed handle 700, the other end of the adjustment handle 502 can easily drive the pin 501 to move through the connector 800, making it easy to control the pin 501 to extend out of the limiting hole.

[0090] By setting a fixed handle 700 and a connector 800 to cooperate with the adjusting handle 502 to control the movement of the pin 501, the control efficiency and operating feel of the pin 501 are improved, and the operating difficulty for the user is reduced. In addition, the fixed handle 700 provides the user with a clear grip point, avoiding misoperation or slippage of the adjusting handle 502 during adjustment. The connector 800 makes the flexibility between the adjusting handle 502 and the pin 501 stronger and the transmission smoother, which can avoid the linkage jamming between the adjusting handle 502 and the pin 501, causing excessive mechanical wear.

[0091] Reference Appendix Figure 3 In some embodiments, the adjustment module further includes a support component 900, which is disposed between the rotating frame 400 and the base frame assembly 100 and connected to both respectively. The support component 900 is used to stop the rotating frame 400 at the preset position when the rotating frame 400 rotates to the preset position.

[0092] Specifically, the support component 900 includes, but is not limited to, an adjustable support rod, an elastic buffer column, a rubber pad, a damper, and a gas spring.

[0093] The support component 900 is located between the rotating frame 400 and the base frame component 100 and is connected to both respectively. It is used to limit the maximum relative rotation angle between the rotating frame 400 and the seat component 200, and to provide structural support for the rotating frame 400 when it rotates to the preset position. It is convenient for the user to control the relative rotation state between the rotating frame 400 and the seat component 200 by locking the component 500.

[0094] The support component 900 provides additional positioning and stopping functions for the rotating frame 400, preventing excessive rotation of the structure due to user misoperation and ensuring safety during use.

[0095] If the pin 501 fails to properly extend into the limiting hole, that is, if the locking component 500 fails and fails to lock the rotating frame 400, the support component 900 serves as a redundant protection measure, improving the reliability of the entire multi-angle chest trainer. At the same time, the support component 900 also improves the operating feel when adjusting the rotating frame 400, making the adjustment process of the rotating frame 400 more stable and clear.

[0096] It should be noted that the maximum relative rotation angle refers to the angle between the two extreme positions when the rotating frame 400 rotates relative to the seat assembly 200. The maximum stroke of the rotating frame 400 is between the two extreme positions.

[0097] Reference Appendix Figure 3 In some embodiments, the support assembly 900 includes a sleeve 901, a sliding rod 902, and a valve. The sleeve 901 is hollow inside and open at one end, with the other end hinged to the base frame assembly 100 or the rotating frame 400. The sliding rod 902 is slidably disposed inside the sleeve 901, with the other end hinged to the rotating frame 400 or the base frame assembly 100 relative to the sleeve 901. The valve is disposed on the sleeve 901.

[0098] Specifically, the sleeve 901 includes, but is not limited to, a metal cylinder and a reinforced plastic housing, to adapt to different load-bearing strength requirements; the sliding rod 902 is provided with a guide groove or a limit ring to improve guiding accuracy and anti-drop function; the valve includes, but is not limited to, a manual adjustment knob, a solenoid control valve, or a pressure feedback adjustment component.

[0099] The sleeve 901 serves as the outer shell component, and its internal cavity is used to accommodate the sliding rod 902. Gas or liquid is loaded between the sleeve 901 and the sliding rod 902 as a resistance medium, which is used to buffer the sliding of the sliding rod 902 and the sleeve 901.

[0100] One end of the sleeve 901 is hinged to the base frame assembly 100 or the rotating frame 400, and the sliding rod 902 passes through the open end and is hinged to the rotating frame 400 or the base frame assembly 100 at the other end of the sleeve 901.

[0101] When the rotating frame 400 rotates relative to the seat assembly 200, it drives the sliding rod 902 to extend and retract within the sleeve 901. This movement compresses or stretches the fluid resistance medium within the sleeve 901, thereby generating a damping force or supporting force on the sliding rod 902 in the opposite direction of movement. By adjusting the valve, the flow rate or pressure of the fluid inside and outside the sleeve 901 can be changed, thereby precisely controlling the magnitude of the damping force and ultimately achieving the functions of buffering, speed regulation, and hovering at any position during the rotation of the rotating frame 400.

[0102] The sliding rod 902 and the sleeve 901 work together to effectively distribute the rotational torque, help reduce the load on the locking assembly 500, and extend the mechanical life. Furthermore, when the user performs the locking operation through the locking assembly 500, the damping force generated on the sliding rod 902 resists the accidental shaking of the rotating frame 400, making the position of the rotating frame 400 and the limiting hole relatively stable, which facilitates the user's locking operation.

[0103] Reference Appendix Figure 3 In some embodiments, the base frame assembly 100 includes a base frame 101 and an upright frame 102, and the seat assembly 200 is disposed on the base frame 101; the upright frame 102 is disposed between the seat assembly 200 and the base frame 101 and is connected to both respectively, so as to reserve the movable space of the rotating frame 400 between the seat assembly 200 and the base frame 101.

[0104] Specifically, the base frame 101 serves as the load-bearing platform for the entire trainer, primarily supporting the seat assembly 200. The upright frame 102 connects the seat assembly 200 and the base frame 101 in a fixed or adjustable manner, providing the necessary space for the rotating frame 400 to rotate and adjust freely under or around the seat.

[0105] The upright 102 includes, but is not limited to, a fixed welded structure or an adjustable height telescopic support rod; the cross-sectional shape of the upright 102 is rectangular, circular, T-shaped or I-shaped to adapt to different load-bearing requirements.

[0106] The cooperation between the base frame 101 and the upright frame 102 not only improves the space utilization efficiency, but also provides ample movement space for the rotating frame 400 and other components mounted on the rotating frame 400, which helps to achieve a wider range of adjustment of the rotating frame 400.

[0107] Reference Appendix Figure 3 and Figure 4 In some embodiments, the seat assembly 200 includes a mounting frame 201, a seat cushion 202, and a telescopic mechanism 203. The mounting frame 201 is mounted on the base frame assembly 100, and the rotating frame 400 is rotatably mounted on the mounting frame 201. The seat cushion 202 is located on the side of the mounting frame 201 away from the rotating frame 400. The telescopic mechanism 203 is mounted on the mounting frame 201 and connected to the seat cushion 202. The telescopic mechanism 203 is used to move the seat cushion 202 closer to or away from the rotating frame 400.

[0108] Specifically, the seat assembly 200 also includes a backrest, and the mounting bracket 201 is fixedly connected to the base frame assembly 100, thereby providing an installation platform for the backrest, seat cushion 202, telescopic mechanism 203, and providing a rotatable connection position for the rotating frame 400.

[0109] The back cushion is located at one end of the base frame assembly 100 along the length of the mounting frame 201. The seat cushion 202 is located on the side of the mounting frame 201 away from the rotating frame 400. The seat cushion 202 is connected to the mounting frame 201 through the telescopic mechanism 203. The user can adjust the position of the seat cushion 202 according to the height or training needs based on the telescopic mechanism 203.

[0110] The telescopic mechanism 203 includes, but is not limited to, a rack and pinion structure, an electric push rod, a slide rail with a buckle or a spring positioning mechanism. The telescopic mechanism 203 is used to realize the linear movement of the seat 202 in the direction of approaching or moving away from the rotating frame 400, so as to adjust the position of the user's chest relative to the handle frame assembly 300, thereby optimizing the force path and chest training effect.

[0111] By adjusting the position of the seat cushion 202 in conjunction with the telescopic mechanism 203, the adaptability of the multi-angle chest trainer of this application to different user body types and training movements is significantly improved, enabling users to perform chest training in the best posture, thereby improving training efficiency and movement safety.

[0112] Reference Appendix Figure 2 In some embodiments, the multi-angle chest trainer also includes a resistance frame 1000 and a cushioning pad 1100. The resistance frame 1000 is disposed on the handle frame assembly 300 and is used to attach or detach counterweights to adjust the resistance of the handle frame assembly 300 during chest training. The cushioning pad 1100 is disposed between the resistance frame 1000 and the adjustment module.

[0113] Specifically, the resistance frame 1000 is set on the swing frame 301 of the handle frame assembly 300. The resistance frame 1000 is used to load counterweights of different weights to change the resistance that the handle frame assembly 300 needs to overcome during the training process, thereby adjusting the training intensity. Each swing frame 301 is equipped with a corresponding resistance frame 1000 so that the motion resistance on the two swing frames 301 is kept balanced.

[0114] The resistance frame 1000 includes, but is not limited to, plug-in type, hook type or magnetic type counterweight structure to adapt to different counterweight forms; the materials for manufacturing the resistance frame 1000 can be steel pipe, alloy casting or high-strength plastic, etc., and the specific materials should be adjusted according to strength and cost requirements.

[0115] A buffer pad 1100 is provided between the resistance frame 1000 and the adjustment module to prevent the resistance frame 1000 from directly impacting the adjustment module during the movement of the handle frame.

[0116] The buffer pad 1100 includes, but is not limited to, different types of buffer elements such as foam, rubber, silicone or hydraulic dampers. The specific shape of the buffer pad 1100 includes, but is not limited to, a gasket or a buffer strip.

[0117] By setting the resistance frame 1000, users can flexibly adjust the resistance of the handle frame assembly 300 according to their personal training plan, which enhances the training diversity and applicability of the multi-angle chest trainer of this application; by setting the buffer pad 1100, the impact of the resistance frame 1000 on the adjustment module when it moves with the handle frame assembly 300 can be effectively reduced, which improves the overall stability and service life of the multi-angle chest trainer, while reducing impact noise.

[0118] In this application, when adjusting the rotating frame 400 before training, the user grasps the end of the adjustment handle 502 away from the connector 800 to rotate it relative to the fixed handle 700. The other end of the adjustment handle 502 drives the pin 501 to extend out of the limiting hole through the connector 800. At this time, the relative rotation between the rotating frame 400 and the seat assembly 200 is released. The user can adjust the rotation angle of the rotating frame 400 relative to the seat assembly 200 by grasping the fixed handle 700 until the rotating frame 400 reaches the preset position or completes the preset angle. Then, the user releases the adjustment handle 502, and the reset component drives the pin 501 to extend into the corresponding limiting hole. At this time, the relative rotation between the rotating frame 400 and the seat assembly 200 is locked, and the direction of force applied when pushing the handle frame assembly 300 for training also changes.

[0119] This multi-angle chest trainer uses an adjustment module to rotate the handle frame assembly 300 around the seat assembly 200. Essentially, it establishes an adjustable hub between the seat assembly 200 and the handle frame assembly 300, increasing the degree of freedom. This allows the pivot point of the handle frame assembly 300 to rotate relative to the seat assembly 200 to different positions, thereby changing the direction of the push force when the user uses the handle frame assembly 300 for chest training. Based on the switching of the push force direction, users can perform various chest exercises targeting the upper chest muscles, middle chest muscles, lower chest muscles, and other upper limb muscle groups. A single multi-angle chest trainer can meet the user's diverse chest training needs, reducing training costs.

[0120] Finally, it should be noted that the various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.
