Description

Technical Field

[0001] This application belongs to the field of fitness equipment technology, and in particular relates to a chest press training device. Background Technology

[0002] A chest press machine is a strength training device used to train the pectoralis major and other upper limb muscle groups. It consists of a base frame, a seat, two handles, and a resistance source. The seat is fixed to the base frame, and the two handles are positioned opposite each other on either side of the seat and rotatably connected to the base frame. The resistance source connects to the two handles to provide training resistance. Users sit on the seat and push the handles to perform flat or decline chest press exercises. However, most current chest press machines are limited in function, typically supporting only one direction of chest press training. Switching from flat to decline chest press exercises requires using a separate machine, leading to higher training costs.

[0003] Furthermore, when using a chest press machine for heavy weight training, it can be difficult to initially exert force to push the two handles. Sudden exertion can also lead to excessive joint stress and muscle strain. Therefore, chest press machines typically include an auxiliary starting device to assist upper body force generation through lower limb pedaling. Since the relative positions of the seat and handles change between flat and decline chest press exercises, the starting device needs to be repositioned accordingly to support use by a seated user. Otherwise, if the starting device is too far away, the user cannot naturally extend their legs to pedal; if it is too close, the user is forced to bend their legs, resulting in an abnormal force path. However, current technology lacks an auxiliary starting device compatible with both flat and decline chest press multi-functional machines. Summary of the Invention

[0004] This application addresses, to at least some extent, one of the technical problems in the related art.

[0005] Therefore, this application aims to provide a chest press trainer that uses a sliding component to slide the seat component, making the relative position of the seat component and the handle frame component adjustable. Simultaneously, based on the connection relationship between the seat component and the sliding component and the base frame component, the seat component rotates relative to the handle frame component during the sliding process, allowing the user sitting on the seat component to push the handle frame component from different directions to perform chest press training. Different chest press training types can be switched based on the direction of push, and a single chest press trainer can meet the user's various chest press training needs, solving the problem of high training costs in existing technologies.

[0006] This application provides a chest press training device, including: Base frame assembly; The handle assembly has one end rotatably mounted on the base frame assembly, and the other end is used for gripping to rotate relative to the base frame assembly; A resistance source assembly, connected to the handle frame assembly, is used to provide resistance against the rotation of the handle frame assembly; A sliding component is slidably mounted on the base frame assembly; A seat assembly, the bottom of which is rotatably connected to the sliding assembly, and the back cushion of the seat assembly is rotatably connected to the base frame assembly; The sliding component is used to drive the seat component to slide along the base frame component, so as to adjust the relative position of the seat component and the handle frame component, so that the user can push the handle frame component from different directions in different sitting positions to perform chest push training.

[0007] In some embodiments, the chest press trainer further includes: An auxiliary component is rotatably mounted on the seat assembly and can move with the seat assembly relative to the base frame assembly. When the user performs chest push training in different sitting positions, the auxiliary component can reduce the resistance of the initial chest push movement.

[0008] In some embodiments, the auxiliary component includes: A rotating beam is rotatably connected to the seat assembly, with both ends of the rotating beam extending toward the resistance source assembly; The step beam has one end mounted on the rotating beam and the other end facing away from the rotating beam. The lifting component has one end rotatably mounted on the base frame assembly, and the other end abuts against the resistance source assembly; The connector is rotatably connected to the rotating beam at one end and to the lifting component at the other end.

[0009] In some embodiments, the chest press trainer further includes: A reset component is disposed between the seat assembly and the auxiliary assembly and is rotatably connected to both. After the auxiliary assembly drives the resistance source assembly, the reset component is used to return the auxiliary assembly to its initial position.

[0010] In some embodiments, the chest press trainer further includes: A limiting component is disposed between the sliding component and the base frame component, and the limiting component is used to lock or release the sliding component relative to the base frame component.

[0011] In some embodiments, the limiting component includes: A mounting base is provided on the sliding assembly; A limiting member is slidably disposed on the mounting base, and the limiting member is used to extend into or out of the mounting base to release or lock the relative sliding of the sliding assembly and the base frame assembly; An elastic element is disposed between the limiting member and the mounting base. The elastic element is used to keep the limiting member extended from the mounting base, so as to elastically lock the relative sliding of the sliding assembly and the base frame assembly.

[0012] In some embodiments, the chest press trainer further includes: The first pedal is mounted on the base frame assembly and located on one side of the seat assembly; The second pedal is located above the first pedal.

[0013] In some embodiments, the seat assembly further includes: The mounting bracket is rotatably mounted on the sliding assembly, and the back pad is mounted on the mounting bracket; The seat cushion is slidably mounted on the mounting bracket; An adjustment mechanism is provided between the mounting frame and the seat cushion, and the adjustment mechanism is used to adjust and / or lock the position of the seat cushion on the mounting frame.

[0014] In some embodiments, the base frame assembly includes: The base, the handle frame assembly and the resistance source assembly are rotatably mounted on the base, and the sliding assembly is slidably mounted on the base; The support frame has one end mounted on the base and the other end extending toward the seat assembly; The support member is rotatably connected to the upright frame at one end and to the back cushion of the seat assembly at the other end.

[0015] In some embodiments, the resistance source component includes: The swing frame has one end rotatably mounted on the base frame assembly, and the other end is used to load and unload counterweights to increase or decrease the rotational resistance of the swing frame relative to the base frame assembly. A transmission rod is rotatably disposed at one end between the two ends of the swing frame, and rotatably connected to the handle frame assembly at the other end. The transmission rod is used to transmit power between the swing frame and the handle frame assembly so that the movements of the two affect each other and move in unison.

[0016] In summary, this application provides a chest press trainer that uses a sliding component to slide the seat component, allowing the relative position of the seat component and the handle frame component to be adjustable. Furthermore, based on the connection between the seat component and the sliding component and the base frame component, the seat component rotates relative to the handle frame component during the sliding process. This allows a user sitting on the seat component to push the handle frame component from different directions to perform chest press exercises. Different chest press training types can be switched based on the direction of push, allowing a single chest press trainer to meet various chest press training needs of the user and solving the problem of high training costs in existing technologies. It is understood that the position of the handle frame component remains unchanged during the sliding of the seat component relative to the base frame component. Based on the different positions of the seat component, the user has at least two sitting positions: a flat chest press position and a decline chest press position. This device allows for both flat and decline chest press training.

[0017] By rotating the auxiliary component onto the seat assembly, and allowing the auxiliary component to move with the seat assembly relative to the base frame assembly, the relative position of the auxiliary component and the seat assembly remains essentially unchanged during the sliding of the sliding component. In other words, when performing flat chest press and decline chest press exercises, the user can use this auxiliary component to reduce the resistance of the initial chest press movement. Flat chest press and decline chest press trainers can share a single set of auxiliary components for assisted start.

[0026] Reference Appendix Figures 1 to 8 This application provides a chest press training device, including a base frame assembly 100, a handle frame assembly 200, a resistance source assembly 300, a sliding assembly 400, and a seat assembly 500.

[0027] The handlebar assembly 200 is rotatably mounted on the base frame assembly 100 at one end, and the other end is used by the user to grip and rotate relative to the base frame assembly 100. The resistance source assembly 300 is connected to the handlebar assembly 200 and is used to provide resistance against the rotation of the handlebar assembly 200. The sliding assembly 400 is slidably mounted on the base frame assembly 100. The bottom end of the seat assembly 500 is rotatably connected to the sliding assembly 400, and the back cushion 503 of the seat assembly 500 is rotatably connected to the base frame assembly 100.

[0028] The sliding component 400 is used to drive the seat component 500 to slide along the base frame component 100 to adjust the relative position of the seat component 500 and the handle frame component 200, so that the user can push the handle frame component 200 from different directions in different sitting positions to perform chest push training.

[0029] Specifically, the base frame assembly 100 is disposed on a bearing plane, the sliding assembly 400 is slidably disposed on the base frame assembly 100, and the bottom end of the seat assembly 500 is rotatably disposed on the sliding assembly 400, so that it can slide relative to the base frame assembly 100 with the sliding assembly 400.

[0030] The handle frame assembly 200 and the resistance source assembly 300 are rotatably mounted on the base frame assembly 100. The handle frame assembly 200 includes two push frames, which are positioned opposite each other on both sides of the sliding direction of the seat assembly 500 and rotatably connected to the base frame assembly 100 at one end. The two push frames have handles at the ends away from the base frame assembly 100, which are convenient for users to grip the handles to push the push frames for chest press training. The resistance source assembly 300 is connected to the push frames to provide training resistance. The number and shape of the handles should be set according to the actual situation.

[0031] In addition, the backrest 503 of the seat assembly 500 is rotatably connected to the base frame assembly 100. That is, when the bottom of the seat assembly 500 slides relative to the base frame assembly 100 with the sliding assembly 400, the other end of the seat assembly 500 is also rotatably connected to the base frame assembly 100. Therefore, the seat assembly 500 also rotates during the sliding process.

[0032] When the moving component moves the seat assembly 500 away from the handlebar assembly 200, the base frame assembly 100 pushes the seat assembly 500 to rotate counterclockwise relative to the sliding component 400. When the user sits on the seat assembly 500, the two handles on the handlebar assembly 200 move relative to each other to the front of the user, allowing the user to push the handlebar assembly 200 for flat pushing training.

[0033] When the moving component moves the seat assembly 500 closer to the handlebar assembly 200, the base frame assembly 100 pulls the seat assembly 500 to rotate clockwise relative to the sliding component 400. When the user sits on the seat assembly 500, the two handles on the handlebar assembly 200 move diagonally above the user, allowing the user to push the handlebar assembly 200 to perform decline chest press training.

[0034] The chest press trainer of this application slides the seat assembly 500 via the sliding component 400, so that the relative position of the seat assembly 500 and the handle frame assembly 200 is adjustable. At the same time, based on the connection relationship between the seat assembly 500 and the sliding component 400 and the base frame assembly 100, the seat assembly 500 rotates relative to the handle frame assembly 200 during the sliding process. This allows the user sitting on the seat assembly 500 to change the relative position around the handle frame assembly 200 and push the handle frame assembly 200 from different directions to perform chest press training, thereby stimulating the chest muscle group from different angles. Based on one chest press trainer, it can meet the different chest press training needs of users.

[0035] Reference Appendix Figures 1 to 4 In some embodiments, the seat assembly 500 includes a seat cushion 502, a back cushion 503, a mounting bracket 501, and an adjustment mechanism 700. The mounting bracket 501 is rotatably mounted on the sliding assembly 400, and the back cushion 503 is mounted on the mounting bracket 501. The seat cushion 502 is slidably mounted on the mounting bracket 501. The adjustment mechanism 700 is located between the mounting bracket 501 and the seat cushion 502, and is used to adjust and / or lock the position of the seat cushion 502 on the mounting bracket 501.

[0036] Specifically, one end of the mounting bracket 501 is rotatably mounted on the sliding assembly 400, and the other end of the mounting bracket 501 extends away from the base frame assembly 100. The back pad 503 is mounted on the mounting bracket 501 along the extension direction of the mounting bracket 501, and the back pad 503 is rotatably connected to the base frame assembly 100.

[0037] When the sliding component 400 causes one end of the mounting bracket 501 and the back pad 503 to slide relative to the base frame assembly 100, and the back pad 503 rotates and connects to the base frame assembly 100, the mounting bracket 501 and the back pad 503 gradually tilt relative to the base frame assembly 100 during the sliding process, and the user's sitting posture with the back of the back pad 503 changes accordingly.

[0038] The seat cushion 502 is slidably mounted on the mounting frame 501 and slides along the extension direction of the mounting frame 501, thereby allowing the user sitting on the seat cushion 502 to move away from or towards the base frame assembly 100; the adjustment mechanism 700 is located between the mounting frame 501 and the seat cushion 502, for the user to adjust the position of the seat cushion 502 on the mounting frame 501, and can lock the seat cushion 502 in a suitable position for chest press training.

[0039] The adjustment mechanism 700 includes, but is not limited to, gas springs, pin positioning structures, lead screw and nut combination structures, hydraulic cylinder structures, and electric linear actuator structures.

[0040] The adjustment mechanism 700 adapts the seat cushion 502 to users of different heights, ensuring that when the user sits on the seat cushion 502, both feet can step on the first pedal 900 or the second pedal 1000 to exert force stably.

[0041] In addition, the mounting bracket 501 tilts relative to the base frame assembly 100 during the sliding process, which at the same time causes the seat cushion 502 to deflect relative to the base frame assembly 100. The user sitting on the seat cushion 502 changes his or her sitting posture accordingly. The seat cushion 502 and the back cushion 503 work together to support the user in adjusting his or her sitting position. Then, the user pushes the handle frame assembly 200 from different directions to perform chest push training.

[0042] Reference Appendix Figure 1 and Figure 6In some embodiments, the chest push trainer of this application further includes an auxiliary component 600, which is rotatably disposed on the seat assembly 500 and can move with the seat assembly 500 relative to the base frame assembly 100. When the user performs chest push training in different sitting positions, the auxiliary component 600 can reduce the resistance of the initial chest push movement.

[0043] Specifically, the auxiliary component 600 is mounted on the seat assembly 500. When the sliding component 400 slides relative to the base frame assembly 100, the seat assembly 500 and the auxiliary component 600 slide relative to the base frame assembly 100. The relative positional relationship between the auxiliary component 600 and the seat assembly 500 is relatively stable, thus avoiding situations where the user cannot naturally extend their leg to step on the auxiliary component 600 or needs to bend their leg to step on the auxiliary component 600 after the position of the seat assembly 500 is adjusted.

[0044] In addition, the auxiliary component 600 is rotatably mounted on the seat component 500 and can rotate relative to the seat component 500 around the rotatable connection between the two. The auxiliary component 600 is also connected to the resistance source component 300.

[0045] By rotating the auxiliary component 600 relative to the seat component 500, the resistance source component 300 can be driven, thereby releasing some resistance from the resistance source component 300. When the user begins the chest push-up action, the auxiliary component 600 drives the resistance source component 300 to reduce the initial resistance on the handle frame component 200, which helps to initiate the chest push-up action, reduces the risk of muscle tearing, and avoids instantaneous impact on the joints.

[0046] Reference Appendix Figures 1 to 8 In some embodiments, the auxiliary component 600 includes a rotating beam 601 and a footrest beam 602. The rotating beam 601 is rotatably connected to the seat assembly 500, and both ends of the rotating beam 601 extend toward and are connected to the resistance source assembly 300. One end of the footrest beam 602 is disposed on the rotating beam 601, and the other end faces away from the extension direction away from the two ends of the rotating beam 601, and is used for stepping to drive the rotating beam 601 to rotate relative to the sliding assembly 400.

[0047] Specifically, the rotating beam 601 further includes a crossbeam portion, two first connecting portions and a second connecting portion, wherein the two first connecting portions are fixed at both ends of the crossbeam portion and the other end of the two first connecting portions is connected to the resistance source assembly 300, the second connecting portion is fixed at the crossbeam portion and located between the two first connecting portions, and the other end of the second connecting portion is rotatably connected to the seat assembly 500.

[0048] One end of the footrest beam 602 is fixed to the crossbeam and located between the two first connecting parts. The other end of the footrest beam 602 extends in the opposite direction to the two first connecting parts and is used for user stepping on the seat assembly 500.

[0049] The footrest beam 602 and the rotating beam 601 work together to form a lever mechanism, wherein the footrest beam 602 is the first lever arm, the rotating beam 601 is the second lever arm, and the rotating connection between the second connecting part and the seat assembly 500 is the pivot point of the lever.

[0050] When a user sitting on the seat assembly 500 steps on the footrest beam 602, it will cause the crossbeam to rotate relative to the seat assembly 500, thereby causing the two first connecting parts to release some resistance from the resistance source assembly 300, which in turn reduces the initial resistance experienced by the handlebar assembly 200, helps to initiate the chest push action, reduces the risk of muscle tearing, and avoids instantaneous impact on the joints.

[0051] Reference Appendix Figure 3 , Figure 5 , Figure 8 In some embodiments, the extension length of the foot beam 602 is greater than the extension length of the first connecting part, that is, the length of the first lever arm of the lever mechanism is greater than the length of the second lever arm, so that the user can save effort when driving the resistance source component 300 by stepping on the foot beam 602.

[0052] Reference Appendix Figures 1 to 8 In some embodiments, the foot pedal is provided at the end of the foot beam 602 away from the rotating beam 601. One end of the foot pedal is fixedly connected to the foot beam 602, and the other end extends away from the foot beam 602. The foot pedal is provided with anti-slip texture to facilitate the user to exert force, thereby driving the foot beam 602 to move through the foot pedal.

[0053] Reference Appendix Figure 3 , Figure 5 , Figure 8 The auxiliary component 600 also includes a lifting member 603 and a connecting member 604. One end of the lifting member 603 is rotatably mounted on the base frame assembly 100, and the other end abuts against the resistance source assembly 300. One end of the connecting member 604 is rotatably connected to the rotating beam 601, and the other end is rotatably connected to the lifting member 603.

[0054] Specifically, one end of the lifting component 603 is rotatably mounted on the base frame assembly 100, and the other end abuts against the resistance source assembly 300.

[0055] The lifting component 603 uses one end as the pivot point, while the other end slides or rolls against the resistance source component 300. This ensures that the direction of the force that drives the resistance source component 300 is always perpendicular to the bearing plane and upwards during the rotation of the lifting component 603 relative to the base frame component 100, thus stably supporting the resistance source component 300.

[0056] In addition, when the sliding component 400 drives the rotating beam 601 to move along the base frame component 100, based on the mutual rotational connection between the connecting member 604, the lifting member 603, and the rotating beam 601, the lifting member 603 will not drive the resistance source component 300 to move, making it convenient for the user to adjust the position of the sliding component 400 and the seat component 500.

[0057] The connector 604 includes, but is not limited to, a connecting rod, a crank, and a telescopic mechanism. One end of the connector 604 is rotatably connected to the first connecting part of the rotating beam 601, and the other end is rotatably connected to the lifting member 603.

[0058] Connector 604 serves as an intermediate connecting component. During the sliding of the rotating beam 601 with the sliding assembly 400, connector 604 prevents the lifting component 603 from moving when adjusting the seat assembly 500. This allows the auxiliary assembly 600 to adapt to both flat and incline chest press training positions. Simultaneously, the connector 604 ensures that the initial auxiliary starting height of the foot pedal beam 602 is appropriate in both flat and incline chest press positions, facilitating user foot pedaling. Furthermore, the rotating beam 601 transmits force to the lifting component 603 through connector 604. The angle between the first connecting part of the rotating beam 601 and connector 604 is less than 180°, and the angle between connector 604 and lifting component 603 is also less than 180°, ensuring that the force applied by the rotating beam 601 to the lifting component 603 remains effective.

[0059] The connector 604 is essentially used to ensure that the force transmission path is adjustable and has a flexible angle compensation function, so that the force on the rotating beam 601 can be smoothly transmitted to the lifting member 603 under any circumstances, effectively converting the power applied by the user to the rotating beam 601 into a force on the resistance source component 300, thereby stably driving the resistance source component 300.

[0060] By setting the lifting component 603 and the connecting component 604 to cooperate, the connection path between the rotating beam 601 and the resistance source assembly 300 has dynamic adaptability. It can automatically adapt to the optimal force transmission angle between the first connecting part and the connecting component 604, and between the connecting component 604 and the lifting component 603, depending on the different positions of the rotating beam 601 along its sliding direction, thereby ensuring the stability and efficiency of the resistance transmission process.

[0061] Reference Appendix Figure 3 , Figure 4 , Figure 5 , Figure 8 In some embodiments, the chest push trainer of this application further includes a reset component 800, which is disposed between the seat component 500 and the auxiliary component 600 and rotatably connected to both. After the auxiliary component 600 drives the resistance source component 300, the reset component 800 is used to return the auxiliary component 600 to its initial position.

[0062] Specifically, the reset component 800 includes, but is not limited to, springs, compression springs, tension springs, pneumatic or hydraulic return mechanisms, used to provide a reset force to return the auxiliary component 600 to its initial position, while avoiding affecting the user's ability to drive the resistance source component 300 through the auxiliary component 600.

[0063] One end of the reset component 800 is rotatably connected to the seat component 500, and the other end is connected to the crossbeam of the rotating beam 601, so that the auxiliary component 600 compresses or releases the reset component 800 between the two during the movement of the auxiliary component 600 relative to the seat component 500, thereby causing the auxiliary component 600 to automatically return to the initial position after the action is completed through the reset component 800.

[0064] During training, the auxiliary component 600 rotates relative to the seat component 500 under the user's stepping force. The auxiliary component 600 drives the resistance source component 300 to lift up while compressing the reset component 800. The reset component 800 converts the kinetic energy transmitted by the auxiliary component 600 into elastic potential energy.

[0065] After the user finishes stepping on the assist component 600, the resistance source component 300 continues to be pushed by the handle component 200 to continue the chest press training. The reset component 800 releases elastic potential energy to push the assist component 600 back to its initial position, ensuring that the assist component 600 has the same starting state the next time it is used.

[0066] By setting the reset component 800, the starting position of the auxiliary component 600 is kept consistent for each training movement, reducing the need for manual reset by the user, improving training efficiency and convenience, and making it easier for users to use the auxiliary component 600 to assist in starting chest press training; at the same time, it avoids structural interference or malfunctions caused by the auxiliary component 600 remaining in a non-initial position.

[0067] It should be noted that the initial position of the auxiliary component 600 refers to its natural position when it is not stepped on by the user.

[0068] Reference Appendix Figure 3 , Figure 5 , Figure 8 In some embodiments, the base frame assembly 100 includes a base 101, an upright 102, and a support member 103. The handle frame assembly 200 and the resistance source assembly 300 are rotatably mounted on the base 101, and the sliding assembly 400 is slidably mounted on the base 101. One end of the upright 102 is mounted on the base 101, and the other end extends toward the seat assembly 500. One end of the support member 103 is rotatably connected to the upright 102, and the other end is rotatably connected to the back cushion 503 of the seat assembly 500.

[0069] Specifically, the base 101 includes, but is not limited to, a welded steel frame structure, an aluminum alloy profile frame, or an integral injection molded part.

[0070] The base 101, as the main platform of the base frame assembly 100, is set on the bearing plane to support and stabilize the overall structure. The handle frame assembly 200 and the resistance source assembly 300 are rotatably mounted on the base 101, and the sliding assembly 400 is slidably mounted on the base 101. The base 101 can provide a stable sliding track for the sliding assembly 400.

[0071] One end of the upright frame 102 is located on the base 101, and the other end extends away from the bearing plane and closer to the seat assembly 500. The upright frame 102 includes, but is not limited to, a single column structure or a bilateral symmetrical frame structure.

[0072] The support frame 102 extends from the base 101 to the vicinity of the seat assembly 500 as an intermediate support skeleton, improving the structural strength of the seat assembly 500 in the suspended state, and providing a support foundation for the seat assembly 500.

[0073] One end of the support member 103 is rotatably connected to the upright frame 102, and the other end is rotatably connected to the back cushion 503 of the seat assembly 500. The support member 103 includes, but is not limited to, straight rods, bent rods, and telescopic rods.

[0074] The support member 103 is used to form a flexible support between the seat assembly 500 and the base frame, supporting the seat assembly 500 to change a certain angle relative to the upright frame 102 during the sliding process, and ensuring that the upright frame 102 maintains the support strength for the seat assembly 500.

[0075] The flexible support mechanism formed by the stand 102 and the support member 103 improves the support performance of the seat assembly 500 under different load conditions, maintains the support strength of the seat assembly 500, and enables the seat assembly 500 to stably support users of different body types and weights.

[0076] In some embodiments, a limiting component is disposed between the sliding component 400 and the base frame component 100, and the limiting component is used to lock or release the sliding component 400 and the base frame component 100 relative to each other.

[0077] Specifically, the limiting components include, but are not limited to, pin limiting components, friction clamping limiting components, and electromagnetic locking components.

[0078] The sliding assembly 400 further includes a sliding seat and rolling elements. Multiple rolling elements are disposed between the base 101 and the sliding seat so that the sliding seat can slide relative to the base 101. The seat assembly 500 and the auxiliary assembly 600 are rotatably mounted on the sliding seat.

[0079] In some embodiments, the limiting component is a pin limiting component, which includes a mounting base, a limiting member, and an elastic member. The mounting base is disposed on the sliding component 400. The limiting member is slidably disposed on the mounting base and is used to extend into or out of the mounting base to release or lock the relative sliding between the sliding component 400 and the base frame assembly 100. The elastic member is disposed between the limiting member and the mounting base and is used to keep the limiting member in the extended state of the mounting base to elastically lock the relative sliding between the sliding component 400 and the base frame assembly 100.

[0080] Specifically, the base 101 has multiple limiting holes along the sliding direction of the sliding assembly 400. The mounting seat is located on the sliding seat, and the limiting member is slidably located in the mounting seat. The limiting member passes through the mounting seat and slides into or out of the limiting hole so that the relative sliding of the sliding seat and the base 101 is locked or released.

[0081] An elastic element is disposed between the limiting element and the mounting base to keep the limiting element extended from the mounting base, thereby elastically locking the relative sliding of the sliding assembly 400 and the base frame assembly 100. That is, after the limiting element is pulled out of the limiting hole to adjust the relative position of the sliding base and the base 101, the elastic element can drive the limiting element to return to the initial locked state. The elastic element includes, but is not limited to, compression springs, tension springs, and rubber.

[0082] It should be noted that the initial locking state refers to the state in which the limiting member is inserted into the limiting hole to lock the sliding seat and the base 101 in relative sliding. The user needs to remove the limiting member from the limiting hole to release the sliding seat and the base 101 from relative sliding. The elastic member will drive the positioning member to re-insert into the corresponding limiting hole after the user releases the force.

[0083] In other embodiments, the limiting component is a friction clamping limiting component, which includes clamping blocks, locking screws and nuts. The two clamping blocks are located on opposite sides of the base 101, the nuts are fixedly mounted on the sliding seat, and the locking screws are threaded to the nuts and pass through the sliding seat to connect with the two clamping blocks. When the locking screws are rotated to bring the two clamping blocks closer together to grip the base 101, the relative sliding of the sliding component 400 and the base frame component 100 can be locked.

[0084] In other embodiments, the limiting component is an electromagnetic locking component, which includes an electromagnet, a power supply, and a control switch. The electromagnet is disposed on the sliding base and is electrically connected to the power supply. The control switch is disposed between the electromagnet and the power supply. When the control switch is turned on, the electromagnet is charged and will attract the base 101, thereby achieving the technical effect of locking the relative sliding of the sliding component 400 and the base frame component 100.

[0085] Reference Appendix Figure 1 and Figure 6In some embodiments, the base frame assembly 100 is further provided with a first pedal 900 and a second pedal 1000. The first pedal 900 is provided on the base frame assembly 100 and located on one side of the seat assembly 500; the second pedal 1000 is provided above the first pedal 900.

[0086] Specifically, the first pedal 900 is a basic pedal set on the base 101, with a large stepping area, which is convenient for users to step on when getting on and off the machine or when doing flat push training. The first pedal 900 is provided with anti-slip texture.

[0087] The second pedal 1000 is a booster pedal installed on the first pedal 900. The stepping area of ​​the second pedal 1000 is smaller than that of the first pedal 900, and the stepping surface of the second pedal 1000 is closer to the seat assembly 500 than the stepping surface of the first pedal 900.

[0088] When the posture of the seat assembly 500 is changed to be used for decline chest press training, the user sitting on the seat assembly 500 actually moves a certain distance away from the first pedal 900. Therefore, there is a situation where the user cannot see the pedal position or step on the first pedal 900.

[0089] By setting up a second pedal 1000, users can quickly find the smaller, more prominent second pedal 1000 with their legs, and conveniently step on the second pedal 1000 to perform decline chest press training.

[0090] The design of the first pedal 900 and the second pedal 1000 enables the chest press trainer of this application to adapt to changes in seat posture and provide a suitable pedal position, while also supporting users of different heights and leg lengths.

[0091] In some embodiments, a telescopic assembly is provided between the first pedal 900 and the second pedal 1000, the telescopic assembly being used to adjust the distance between the first pedal 900 and the second pedal 1000.

[0092] Reference Appendix Figure 3 , Figure 5 , Figure 8 In some embodiments, the resistance source assembly 300 includes a swing frame 301 and a transmission rod 302. One end of the swing frame 301 is rotatably mounted on the base frame assembly 100, and the other end is used to load and unload counterweights to increase or decrease the rotational resistance of the swing frame 301 relative to the base frame assembly 100. One end of the transmission rod 302 is rotatably mounted between the two ends of the swing frame 301, and the other end is rotatably connected to the handle frame assembly 200. The transmission rod 302 is used to transmit power between the swing frame 301 and the handle frame assembly 200 so that the movements of the two affect each other and move in unison.

[0093] Specifically, one end of each of the two swing frames 301 is rotatably mounted on the base 101, and the other end is set as a counterweight loading part, which is used to install counterweights of different masses according to training needs, thereby adjusting the resistance of the entire swing frame 301 when rotating relative to the base frame.

[0094] One end of the transmission rod 302 is rotatably connected to the swing frame 301, and the other end is rotatably connected to the handle frame assembly 200, so that the transmission rod 302 and the swing frame 301 are linked together.

[0095] On the one hand, when the user pushes the handle frame assembly 200, the pushing force is transmitted to the swing frame 301 through the transmission rod 302, so that the swing frame 301 rotates relative to the base frame. During the rotation, it is necessary to overcome the gravitational torque formed by the counterweight to perform chest press training.

[0096] On the other hand, when the auxiliary component 600 drives the swing frame 301 to rotate relative to the base frame, the transmission rod 302 will also drive the handle frame assembly 200 to rotate relative to the base frame, so as to reduce the initial resistance experienced by the handle frame assembly 200.

[0097] The transmission rod 302 ensures close linkage between the swing frame 301 and the handle frame assembly 200, forming a dynamic two-way linkage system. This system not only achieves mechanical resistance adjustment and force transmission path optimization, but also assists the handle frame assembly 200 in starting.

[0098] Reference Appendix Figures 1 to 4 When adjusting the chest press trainer of this application to prepare for flat press training, the sliding component 400 drives the seat component 500 to slide away from the first pedal 900, so that the seat cushion 502 of the seat component 500 gradually tends to be parallel to the bearing plane. Until the user sits on the seat cushion 502, the handle frame component 200 is located directly in front of the user. The relative sliding of the sliding component 400 and the base frame component 100 is locked by the limiting component, ensuring that the user can grasp the handle frame component 200 and push it directly in front of him to perform flat press chest training.

[0099] Reference Appendix Figures 6 to 8 When adjusting the chest press trainer of this application to prepare for decline chest press training, the sliding component 400 drives the seat component 500 to slide closer to the first pedal 900, so that the seat cushion 502 of the seat component 500 gradually becomes perpendicular to the bearing plane. When the user sits on the seat cushion 502, the handle frame component 200 is located diagonally above the user. The relative sliding of the sliding component 400 and the base frame component 100 is locked by the limiting component, ensuring that the user can grasp the handle frame component 200 and push it in front of him and upward to perform decline chest press training.

[0100] Reference Appendix Figure 1 , Figure 5 , Figure 6 When using the chest press trainer of this application for flat and incline press training, after adjusting the position of the seat assembly 500 and the auxiliary assembly 600 accordingly through the limiting component, the user sits on the seat assembly 500, grabs the handle frame assembly 200 and steps on the first pedal 900 or the second pedal 1000.

[0101] The user places one leg on the footrest beam 602 to transmit force to the resistance source assembly 300 through the connector 604 and the lifting member 603. At the same time, the user grips the handle frame assembly 200 to transmit force to the resistance source assembly 300 through the transmission rod 302. After the resistance source assembly 300 rotates at a preset angle relative to the base frame assembly 100, the user's leg releases the force and the user performs horizontal and downward push training by reciprocating the push of the handle frame assembly 200 with both hands.

[0102] It should be noted that the preset angle should be set based on the user's training needs.

[0103] When the sliding component 400 drives the seat component 500 to slide relative to the base frame component 100, the auxiliary component 600 also slides relative to the base frame component 100 along with the sliding component 400. Furthermore, the seat component 500 rotates relative to the sliding component 400 during the sliding process, and the auxiliary component 600 also rotates relative to the sliding component 400 during the sliding process.

[0104] That is, the relative position of the auxiliary component 600 and the seat 502 remains basically unchanged during the movement, thereby ensuring that the auxiliary component 600 can be used stably to assist the handle frame component 200 in starting during flat push and downhill push training.

[0105] This application provides a chest press trainer. By setting a sliding component 400 to slide the seat component 500, the relative position of the seat component 500 and the handle frame component 200 is adjustable. Simultaneously, based on the connection relationship between the seat component 500 and the sliding component 400 and the base frame component 100, the seat component 500 rotates relative to the handle frame component 200 during the sliding process. This allows a user sitting on the seat component 500 to push the handle frame component 200 from different directions to perform chest press exercises. Different chest press training types can be switched based on the direction of push. A single chest press trainer can meet the needs of various users. This invention addresses the diverse chest press training needs of users and solves the problem of high training costs in existing technologies. Compared to existing chest press trainers that require customized starting devices based on the type of chest press training, this application's chest press trainer is equipped with an auxiliary component 600 for foot pedals to help start the handle frame component 200. The auxiliary component 600 also rotates relative to the sliding component 400 as it slides, so that the relative position of the auxiliary component 600 and the seat component 500 remains basically unchanged during the movement. This avoids situations where the user cannot naturally extend their legs or needs to bend their legs to exert force, eliminating the need for customized starting devices for different types of chest press training.

[0106] 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.
