Description

Technical Field

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

[0002] In recent years, with the popularization of fitness awareness, the number of people exercising has continued to rise, which in turn has led to a continuous increase in the demand for fitness equipment.

[0003] Existing training devices include two relatively movable parts. When these two relatively movable parts come into contact, they are prone to impact. Existing technology usually adds a rubber pad between the two relatively movable parts to mitigate the impact.

[0004] However, rubber pads cannot withstand large impacts and usually fail international safety cushioning tests. Utility Model Content

[0005] In view of the shortcomings of the related technologies, this application provides a buffer mechanism and a trainer for a training device. By sliding a buffer member disposed in a first mounting sleeve and an elastic member disposed between the two, the impact when two relatively moving parts come into contact is reduced, thereby providing a better vibration reduction effect for the trainer and improving the training experience of athletes.

[0006] On one hand, this application provides a buffer mechanism for a trainer, comprising:

[0007] A first mounting sleeve, one end of which is disposed on a component of the trainer, the first mounting sleeve being hollow inside and open at the other end;

[0008] A buffer element, which is slidably disposed within the first mounting sleeve;

[0009] An elastic element is provided between the buffer element and the first mounting sleeve;

[0010] The buffer mechanism is located on either of the two relatively movable parts of the trainer to mitigate the impact when the two parts come into contact, and the elastic element is used to convert the impact force on the buffer into elastic potential energy.

[0011] In some embodiments, the buffer mechanism further includes:

[0012] A limiting member is provided at the end of the buffer member away from the first mounting sleeve, and the outer diameter of the limiting member is larger than the inner diameter of the first mounting sleeve.

[0013] In some embodiments, when the limiting member contacts another component of the trainer, the ends of the two components that are in contact with each other are perpendicular to each other at least on the same contact plane.

[0014] On the other hand, this application also provides a trainer including the buffer mechanism described in any of the above claims.

[0015] In some embodiments, the trainer further includes:

[0016] Base frame assembly;

[0017] A swing frame assembly is rotatably mounted on the base frame assembly. One end of the first mounting sleeve of the buffer mechanism is located on the swing frame assembly. The buffer mechanism is used to reduce the impact between the swing frame assembly and the base frame assembly.

[0018] In some embodiments, the trainer further includes:

[0019] A second mounting sleeve, one end of which is disposed on the base frame assembly relative to the first mounting sleeve, the second mounting sleeve being hollow inside and open at the other end;

[0020] An adjusting member is slidably disposed within the second mounting sleeve. The adjusting member is used to contact the buffer member and slide relative to the second mounting sleeve to adjust its contact position with the buffer member.

[0021] In some embodiments, the adjusting member and the second mounting sleeve are provided with a plurality of corresponding limiting holes, and a limiting member is slidably provided in the limiting hole. The limiting member is used to lock or release the relative sliding of the adjusting member and the second mounting sleeve.

[0022] In some embodiments, the base frame assembly includes:

[0023] A longitudinal frame, one end of which is rotatably connected to the swing frame assembly;

[0024] A horizontal frame is provided at the other end of the vertical frame, and the second mounting is sleeved on the horizontal frame;

[0025] The pedal is connected at both ends to the crossbar and the longitudinal bar, respectively.

[0026] In some embodiments, the chassis assembly further includes:

[0027] A vertical frame, which is mounted on the horizontal frame and located on one side of the swing frame assembly;

[0028] A positioning component, wherein the positioning component is disposed on the upright frame;

[0029] A locking element is provided on the swing frame assembly and is used to abut against the locking element.

[0030] In some embodiments, the locking member is rotatably mounted on the swing frame assembly, one end of the locking member is used to abut against the locking member to restrict the swing frame assembly from rotating relative to the longitudinal frame, and the other end of the locking member is used by the athlete to grip and rotate, so that the locking member abuts against or disconnects from the locking member.

[0031] In summary, this application provides a buffer mechanism and a trainer having the same. Through the cooperation of a first mounting sleeve, a buffer member, and an elastic member, the impact force when the base frame assembly and the swing frame assembly come into contact is converted into stored elastic potential energy, thereby reducing impact vibration and assisting the athlete in lifting the swing frame assembly. Through the cooperation of a second mounting sleeve and an adjusting member, the contact position between the base frame assembly and the swing frame assembly is adjusted to suit different athletes' physical characteristics or different training needs. Through the cooperation of a limiting hole and a limiting member, the athlete can easily control the length of the adjusting member sliding out of the second mounting sleeve. The limiting member further reduces the transmission of vibration caused by impact and limits the depth of the buffer member sliding into the first mounting sleeve, enhancing the service life of the elastic member. By ensuring that the ends of the limiting member and the adjusting member are perpendicular to each other on at least one plane when they contact each other, the number of contact points on that plane is maximized, thereby preventing the phenomenon of them not contacting each other.

Figure 1 To be continued Figure 5 Specific Embodiment 1 and Specific Embodiment 2 will be described.

[0047] Reference Appendix Figures 1 to 4 This application provides a buffer mechanism 100, which is disposed between two relatively movable parts of a trainer to mitigate the impact when the two parts come into contact. The buffer mechanism 100 includes a first mounting sleeve 101, a buffer member 102, and an elastic member 103. One end of the first mounting sleeve 101 is disposed on any part of the trainer. The first mounting sleeve 101 is hollow inside and open at the other end. One end of the second mounting sleeve 102 is disposed on the other part of the trainer. The second mounting sleeve 102 is hollow inside and open at the other end. The buffer member 102 is slidably disposed inside the first mounting sleeve 101. The elastic member 103 is disposed between the buffer member 102 and the first mounting sleeve 101. The elastic member 103 is used to convert the impact force received by the buffer member 102 into elastic potential energy for storage. The adjusting member 105 is slidably disposed inside the second mounting sleeve 102. The adjusting member 105 is used to contact the buffer member 102 and slide relative to the second mounting sleeve 102 to adjust its contact position with the buffer member 102.

[0048] Specifically, the materials of the first mounting sleeve 101 include, but are not limited to, high-strength plastic, aluminum alloy, and stainless steel to ensure durability and lightweight; the first mounting sleeve 101 is hollow inside, one end of the first mounting sleeve 101 is connected to any moving part of the trainer, and the other end of the first mounting sleeve 101 is open to accommodate the buffer 102 and the elastic element 103; optionally, the end of the first mounting sleeve 101 used to connect to the moving part is designed as a threaded interface or slot so as to detachably connect with the moving part.

[0049] The materials of the second mounting sleeve 102 include, but are not limited to, high-strength plastic, aluminum alloy, and stainless steel to ensure durability and lightweight. The second mounting sleeve 102 is hollow inside. One end of the second mounting sleeve 102 is connected to another movable part of the trainer relative to the first mounting sleeve 101. The other end of the second mounting sleeve 102 is open to accommodate the adjustment member 105. The openings of the second mounting sleeve 102 and the first mounting sleeve 101 face each other so that when the adjustment member 105, which is slidably disposed inside both, comes into contact with the buffer member 102, vibration reduction is achieved. Optionally, the end of the second mounting sleeve 102 used to connect to the movable part is designed as a threaded interface or slot for detachable connection with the movable part.

[0050] The buffer 102 is slidably disposed within the first mounting sleeve 101. The materials used to make the buffer 102 include, but are not limited to, steel, aluminum, and engineering plastics to ensure strength and durability. The buffer 102 is used to retract into the first mounting sleeve 101 when it contacts the adjusting member 105 and to transfer the impact force to the elastic member 103.

[0051] The materials used to make the elastic element 103 include, but are not limited to, spring steel, rubber band, and elastic rope. The elastic element 103 is a helical spring, leaf spring, or gas spring. The elastic element 103 is used to ensure that the buffer 102 can effectively store elastic potential energy when it is impacted, thereby reducing the impact vibration of the first mounting sleeve 101. The elastic element 103 is also used to release elastic potential energy when the buffer 102 moves away from the adjusting element 105, thereby assisting the buffer 102 to move away from the adjusting element 105 and thus assisting the athlete in power training.

[0052] The adjusting member 105 is slidably disposed within the second mounting sleeve 102. The adjusting member 105 is made of materials including but not limited to steel, aluminum, and engineering plastics to ensure strength and durability. The adjusting member 105 is used to contact the second mounting sleeve 102 to distribute part of the impact force. The adjusting member 105 is also used to slide relative to the second mounting sleeve 102 to adjust its contact position with the buffer member 102, ensuring the precise stroke of the moving parts of the trainer, and adapting to the physical characteristics of different athletes or different training needs to complete the training, thereby improving the user experience of the trainer.

[0053] Reference Appendix Figure 4 In some embodiments, the adjusting member 105 and the second mounting sleeve 102 are provided with a plurality of corresponding limiting holes, and a limiting member 600 is slidably provided in the limiting holes. The limiting member 600 is used to prevent or release the relative sliding between the adjusting member 105 and the second mounting sleeve 102.

[0054] Specifically, the limiting hole on the adjusting member 105 corresponds to the limiting hole on the second mounting sleeve 102. The limiting member 600 includes, but is not limited to, a pin or a rod. When the limiting member 600 extends from one side of the second mounting sleeve 102 into the limiting hole on the second mounting sleeve 102, the limiting hole on the adjusting member 105, and the limiting hole on the other side of the second mounting sleeve 102 in sequence, the relative sliding between the adjusting member 105 and the second mounting sleeve 102 is restricted. The end size of the adjusting member 105 extending from the opening of the second mounting sleeve 102 is temporarily fixed, thereby temporarily fixing the position of the adjusting member 105 when it contacts the buffer member 102, ensuring the accurate stroke of the moving parts of the trainer.

[0055] When the limiting member 600 is pulled out from the limiting hole of the second mounting sleeve 102 and the limiting hole of the adjusting member 105, the relative sliding restriction between the adjusting member 105 and the second mounting sleeve 102 is released, and the size of the end of the adjusting member 105 extending out of the opening of the second mounting sleeve 102 can be adjusted as needed, so as to meet the physical characteristics of different athletes or different training needs to complete the training.

[0056] Reference Appendix Figures 1 to 3 In some embodiments, the end of the buffer 102 away from the first mounting sleeve 101 is also provided with a limiting member 104, the outer diameter of the limiting member 104 being larger than the inner diameter of the first mounting sleeve 101.

[0057] Specifically, the limiting member 104 is made of materials including but not limited to rubber, polyurethane foam, silicone, or other materials with good cushioning properties to reduce the vibration transmitted to the buffer member 102. The outer diameter of the limiting member 104 is larger than the inner diameter of the first mounting sleeve 101 so that the limiting member 104 cannot slide into the first mounting sleeve 101, and the depth to which the buffer member 102 slides into the first mounting sleeve 101 is fixed. The maximum compression of the buffer member 102 on the elastic member 103 is limited to not exceeding a preset value, thereby preventing the elastic member 103 from being over-compressed and deformed, and increasing the service life of the elastic member 103.

[0058] Reference Appendix Figure 1 In some embodiments, when the limiting member 104 and the adjusting member 105 are in contact, their contacting ends are perpendicular to each other on the same contact plane.

[0059] Specifically, the end of the limiting member 104 near the adjusting member 105 has a length direction in the first direction, while the end of the adjusting member 105 near the limiting member 104 has a length direction in the second direction. When the limiting member 104 contacts the adjusting member 105, the first direction and the second direction are perpendicular to each other at least in one plane, thereby maximizing the number of contact points between the limiting member 104 and the adjusting member 105 and preventing the limiting member 104 and the adjusting member 105 from interleaving and not contacting each other due to other errors.

[0060] It should be noted that those skilled in the art should find a plane that makes the first direction and the second direction perpendicular to each other based on the actual situation. In this way, after setting the limiting member 104 and the adjusting member 105 accordingly, the number of contact points between the limiting member 104 and the adjusting member 105 can be maximized. Even if the actual movement trajectory of the limiting member 104 or the adjusting member 105 deviates from the preset movement trajectory, the limiting member 104 and the adjusting member 105 can still contact each other without intersecting. Specific Implementation Example 2

[0062] Reference Appendix Figure 5 This application also provides a training device for squat training. The training device is equipped with the buffer mechanism 100 described in Embodiment 1 above. The training device includes a base frame assembly 200, a swing frame assembly 300, a first mounting sleeve 101, a second mounting sleeve 102, a buffer member 102, an elastic member 103, and an adjusting member 105. The swing frame assembly 300 is rotatably mounted on the base frame assembly 200. One end of the first mounting sleeve 101 is mounted on the swing frame assembly 300. The first mounting sleeve 101 is hollow inside and open at the other end. The second mounting sleeve... One end of the second mounting sleeve 102 is mounted on the base frame assembly 200. The second mounting sleeve 102 is hollow inside and open at the other end. The buffer 102 is slidably disposed inside the first mounting sleeve 101. The elastic element 103 is disposed between the buffer 102 and the first mounting sleeve 101. The elastic element 103 is used to convert the impact force received by the buffer 102 into elastic potential energy for storage. The adjusting element 105 is slidably disposed inside the second mounting sleeve 102. The adjusting element 105 is used to contact the buffer 102 and slide relative to the second mounting sleeve 102 to adjust its contact position with the buffer 102.

[0063] Reference Appendix Figure 5 In some embodiments, the base frame assembly 200 includes a longitudinal frame 201, a transverse frame 202, and a pedal 203; one end of the longitudinal frame 201 is rotatably connected to the swing frame assembly 300, the transverse frame 202 is disposed at the other end of the longitudinal frame 201, the second mounting sleeve 102 is disposed on the transverse frame 202, and the two ends of the pedal 203 are respectively connected to the transverse frame 202 and the longitudinal frame 201.

[0064] Specifically, the longitudinal frame 201, the transverse frame 202, and the pedal 203 are made of high-strength steel or aluminum alloy to ensure their stability and load-bearing capacity during training. The use of high-strength materials can also improve the overall durability of the trainer, avoid deformation or damage after long-term use, and not affect training safety.

[0065] The horizontal frame 202 is laid parallel to a placement plane, and the vertical frame 201 is fixed vertically to one end of the horizontal frame 202. The vertical frame 201 is provided with a placement rack to stack unused counterweights. The two ends of the pedal 203 are connected to the vertical frame 201 and the horizontal frame 202 respectively, so that the pedal 203 is inclined to the placement plane. The horizontal frame 202 is also provided with a load-bearing plate parallel to the placement plane. The load-bearing plate is located on one side of the pedal 203 to provide a standing area for athletes before stepping on the pedal 203.

[0066] The swing frame assembly 300 is rotatably mounted at the end of the longitudinal frame 201 away from the transverse frame 202. When the swing frame assembly 300 rotates relative to the longitudinal frame 201, the end of the swing frame assembly 300 away from the longitudinal frame 201 tends to contact the end of the transverse frame 202 away from the longitudinal frame 201. Therefore, a second mounting sleeve 102 is provided at the end of the transverse frame 202 away from the longitudinal frame 201 to install the adjusting member 105, which is used to cooperate with the buffer member 102 mounted on the swing frame assembly 300 to reduce the impact when they contact each other.

[0067] Reference Appendix Figure 5 In some embodiments, the base frame assembly 200 further includes an upright frame 204, a locking member 205, and a locking member 206. The upright frame 204 is disposed on the cross frame 202 and located on one side of the swing frame assembly 300. The locking member 205 is disposed on the upright frame 204, and the locking member 206 is disposed on the swing frame assembly 300. The locking member 206 is used to abut against the locking member 205.

[0068] Specifically, the locking member 205 is located on the upright 204 at the end away from the horizontal frame 202. During the process of the swing frame assembly 300 rotating relative to the vertical frame 201 to bring the limiting member 104 closer to the adjusting member 105, the locking member 205 is located on the movement path of the swing frame assembly 300. When the locking member 206 on the swing frame assembly 300 abuts against the locking member 205, the relative rotation between the swing frame assembly 300 and the vertical frame 201 is restricted, thereby preventing the limiting member 104 from continuing to approach the adjusting member 105.

[0069] It should be noted that the number of locking pieces 205 should be set according to the actual situation. The locking piece 206, together with multiple locking pieces 205, can restrict the swing frame assembly 300 from rotating to different angles relative to the longitudinal frame 201 as needed, thereby accommodating squat training for athletes of different heights.

[0070] Reference Appendix Figure 5 In some embodiments, the locking member 206 is rotatably disposed on the swing frame assembly 300. One end of the locking member 206 is used to abut against the locking member 205 to restrict the swing frame assembly 300 from rotating relative to the longitudinal frame 201. The other end of the locking member 206 passes through the swing frame assembly to facilitate the athlete's grip and rotation, so that the locking member 206 abuts against or disconnects from the locking member 205.

[0071] Specifically, the locking member 206 passes through the swing frame assembly 300 and rotates relative to the pivot on the swing frame assembly 300. When the athlete rotates one end of the locking member 206 on the side of the swing frame assembly 300 away from the upright 204, the other end of the locking member 206 rotates relative to the pivot until it abuts against the locking member 205, thereby restricting the relative rotation between the swing frame assembly 300 and the longitudinal frame 201. When the athlete rotates one end of the locking member 206 in the opposite direction on the side of the swing frame assembly 300 away from the upright 204, the other end of the locking member 206 rotates relative to the pivot until it separates from the locking member 205, thereby releasing the restriction on the relative rotation between the swing frame assembly 300 and the longitudinal frame 201. This allows the athlete to pause training at any time during exercise, ensuring training safety.

[0072] Reference Appendix Figure 5 In some embodiments, the swing frame assembly 300 includes a swing frame 301, a back pad 302, a shoulder pad 303, and a resistance frame 304. The swing frame 301 is rotatably connected to the base frame assembly 200. A first mounting sleeve 101 is disposed on the swing frame 301, the back pad 302 is disposed on the swing frame 301, the shoulder pad 303 is disposed on the swing frame 301, and the resistance frame 304 is disposed on the swing frame 301.

[0073] Specifically, the swing frame 301 uses high-strength steel or aluminum alloy to ensure its stability and load-bearing capacity during training. One end of the swing frame 301 is rotatably connected to the longitudinal frame 201, and the other end of the swing frame 301 is provided with a first mounting sleeve 101 so that the buffer 102 in the first mounting sleeve 101 corresponds to the adjusting member 105 in the second mounting sleeve 102 on the transverse frame 202.

[0074] The resistance frame 304 is located at the end of the pendulum frame 301 away from the longitudinal frame 201. The resistance frame 304 is used to load counterweights so that the pendulum frame 301 needs to provide greater support force during the rotation of the longitudinal frame 201, thereby improving the training effect when the athlete moves the pendulum frame 301 to do squat training.

[0075] Back pad 302 and shoulder pad 303 are placed on the swing frame 301. The athlete lifts the swing frame 301 with the back pad 302 and shoulder pad 303, and at the same time steps on the pedal 203 to drive the swing frame 301 to rotate relative to the vertical frame 201, thereby performing squat training.

[0076] Reference Appendix Figure 5 In some embodiments, the swing frame assembly 300 further includes an auxiliary frame 305 and a handrail frame 306. One end of the auxiliary frame 305 is rotatably mounted on the base frame assembly 200, and the other end is connected to the swing frame 301. The handrail frame 306 is mounted on the auxiliary frame 305.

[0077] Specifically, one end of the auxiliary frame 305 is rotatably mounted on the longitudinal frame 201, and the other end is connected to the swing frame 301. It is used to assist the swing frame 301 in rotating stably relative to the longitudinal frame 201 and to prevent the swing frame 301 from displacing axially along the rotation axis on the longitudinal frame 201. The auxiliary frame 305 is also used to expand the installation position for installing the shoulder pad 303 and the armrest frame 306. The armrest frame 306 is mounted on the auxiliary frame 305 to provide a gripping position for the athlete, so that the athlete can control the swing of the swing frame 301.

[0078] When athletes use the training device of this application for squat training, they first adjust the length of the adjusting member 105 extending out of the second mounting sleeve 102 by inserting and removing the limiting member 600, and assemble an appropriate amount of counterweight on the resistance frame 304; then, the athlete enters the training area by stepping on the load-bearing plate, lifts the swing frame 301 by the back pad 302 and shoulder pad 303, moves the feet from the load-bearing plate to the inclined pedal 203 with the shoulders and back as the fulcrum, and releases the rotation restriction of the swing frame 301 relative to the longitudinal frame 201 by rotating one end of the locking member 206 to separate the other end from the locking member 205.

[0079] The athlete grips the handrail 306 and squats down to rotate the swing frame 301 relative to the vertical frame 201 until the limiting member 104 contacts the adjusting member 105. The limiting member 104 pushes the buffer member 102 into the first mounting sleeve 101, while compressing the elastic member 103 to convert the impact force generated when the limiting member 104 contacts the adjusting member 105 into elastic potential energy. The athlete grips the handrail 306 and extends his body to rotate the swing frame 301 relative to the vertical frame 201. At the same time, the elastic member 103 releases elastic potential energy to assist the buffer member 102 in extending out of the first mounting sleeve 101, thereby assisting the athlete in extending his body. The above steps are repeated to perform squat training.

[0080] When the athlete wants to stop training, while the body is extended, the athlete can rotate one end of the locking member 206 so that the other end abuts against the locking member 205. The rotation of the swing frame 301 relative to the longitudinal frame 201 will be blocked and restricted by the locking member 205. The swing frame 301 will no longer be able to drive the restricting member 104 to move towards the adjusting member 105. The athlete can then move his feet from the pedal 203 to the inclined load-bearing plate using his shoulders and back as fulcrums, and walk out of the training area to complete the training.

[0081] This application provides a buffer mechanism 100 and a trainer having the same. Through the cooperation of the first mounting sleeve 101, the buffer 102, and the elastic member 103, the impact force when the base frame assembly 200 and the swing frame assembly 300 come into contact is converted into stored elastic potential energy, thereby reducing impact vibration and assisting the athlete in lifting the swing frame assembly 300. Through the cooperation of the second mounting sleeve 102 and the adjusting member 105, the contact position between the base frame assembly 200 and the swing frame assembly 300 is adjusted, thereby adapting to the physical characteristics of different athletes or different training needs to complete the training. The limiting hole and the limiting member 600 cooperate to allow the athlete to easily control the length of the adjusting member 105 sliding out of the second mounting sleeve 102; the limiting member 104 further reduces the transmission of vibration caused by impact and limits the depth of the buffer member 102 sliding into the first mounting sleeve 101, thereby enhancing the service life of the elastic member 103; by ensuring that the ends of the limiting member 104 and the adjusting member 105 are perpendicular to each other at least on a plane when they are in contact, the number of contact points on the plane is maximized, thereby avoiding the phenomenon of the two not contacting each other.
