Description

Technical Field

[0001] This application belongs to the field of fitness equipment technology, and in particular relates to a step-up 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 step-up training devices include a pedal, a base frame, a swing frame, and an angle adjustment component. The base frame and the swing frame are rotatably connected. The pedal is connected to the base frame via the angle adjustment component. After adjusting the tilt angle of the pedal via the angle adjustment component, the user performs single-leg step-up training by stepping on the pedal with one leg and rotating the swing frame relative to the base frame while carrying it on their shoulder.

[0004] However, the angle adjustment component in the above technical solution can only adjust the tilt angle of the pedal. The tilted pedal shortens the squatting stroke and makes it impossible to fully flex and extend the hip during single-leg step-up training, resulting in insufficient stimulation of the gluteal muscles and failing to meet the user's training needs. Utility Model Content

[0005] To address the shortcomings of related technologies, this application provides a step-up trainer. By setting a first distance greater than a second distance, it allows users to perform step-up training by extending their hips diagonally upwards to push against their shoulders, thereby increasing the range of motion of the hips, enhancing the stimulation of the gluteal muscles, and meeting the user's training needs.

[0006] This application provides a step-climbing training device, comprising:

[0007] A base frame assembly, wherein the base frame assembly is disposed on a bearing plane;

[0008] A carrying frame assembly is rotatably mounted on a base frame assembly. The carrying frame assembly has a pivot point and a shoulder support that are rotatably connected to the base frame assembly. The vertical distance between the pivot point and the bearing plane is a first distance, and the vertical distance between the shoulder support and the bearing plane is a second distance. In the initial position, the second distance is greater than the first distance.

[0009] The pedal is mounted on the base frame assembly. The top surface of the pedal is used to form a height difference with respect to the bearing plane. When the first distance is within a preset range, the user steps on the top surface of the pedal with one foot and extends their body diagonally upwards to push against the shoulder support to perform step training.

[0010] In some embodiments, the preset range of the first distance is 600mm to 900mm.

[0011] In some embodiments, the support assembly includes:

[0012] A swing frame, which is rotatably mounted on the base frame assembly based on the pivot point, and the shoulder support is located at one end of the swing frame;

[0013] The first adjustment component has the shoulder support and the pivot point located on opposite sides of the first adjustment component. The first adjustment component is used to adjust the initial vertical height of the shoulder support and the bearing plane.

[0014] In some embodiments, the initial vertical height between the shoulder support and the bearing plane ranges from 1180 mm to 1340 mm.

[0015] In some embodiments, the first regulating component includes:

[0016] A telescopic sleeve is provided on the swing frame and swings relative to the base frame assembly with the swing frame. The shoulder support and the pivot point are located on both sides of the telescopic sleeve.

[0017] A sliding member is slidably disposed within the telescopic sleeve, and the end of the sliding member away from the swing frame is used to abut against the base frame assembly;

[0018] The locking component has matching limiting holes for both the telescopic sleeve and the sliding component. The locking component passes through the limiting holes to lock or release the relative sliding of the telescopic sleeve and the sliding component.

[0019] In some embodiments, the relative sliding displacement range between the slider and the telescopic sleeve is 0 to 100 mm.

[0020] In some embodiments, the top surface of the pedal is nearly parallel to the bearing plane.

[0021] In some embodiments, the step-up trainer further includes:

[0022] The second adjustment component is rotatably mounted on the base frame assembly and rotatably connected to the pedal. The second adjustment component is used to rotate relative to the base frame assembly to push the top surface of the pedal closer to or away from the bearing plane, thereby adjusting the height difference between the top surface of the pedal and the bearing plane.

[0023] In some embodiments, the height of the top surface of the pedal relative to the bearing plane is set in the range of 200mm to 500mm.

[0024] In some embodiments, the second regulating component includes:

[0025] An adjusting component is rotatably mounted on the base frame assembly and is rotatably connected to the pedal.

[0026] The support member has two ends that are rotatably connected to the base frame assembly and the pedal, respectively.

[0027] In some embodiments, the second regulating component further includes:

[0028] A limiting member is fixed on the base frame assembly, and the limiting member is provided with multiple locking points;

[0029] A pin is inserted through the adjusting member and engages with any locking point to lock or release the relative rotation between the adjusting member and the base frame assembly.

[0030] In some embodiments, the second regulating component further includes:

[0031] The second auxiliary component is disposed opposite to the pedal at both ends of the adjusting component, and the rotatable connection between the adjusting component and the base frame assembly is located between the pedal and the second auxiliary component.

[0032] In some embodiments, the mass of the second auxiliary member is greater than the mass of the pedal, and it is used to press down one end of the adjusting member to move the pedal away from the bearing plane.

[0033] In some embodiments, the distance between the shoulder support and the turning point ranges from 1050 mm to 1400 mm.

[0034] In some embodiments, the shoulder support rotates around the pivot point based on an arc-shaped trajectory, the arc length of which ranges from 600mm to 1000mm.

[0035] In some embodiments, the step-up trainer further includes:

[0036] A first auxiliary component is disposed at one end of the swing frame that is relatively far from the shoulder support. The first auxiliary component is used to assist the user in pushing against the shoulder support to drive the swing frame to rotate relative to the base frame assembly.

[0037] In some embodiments, the step-up trainer further includes:

[0038] A resistance component, which is linked to the support frame assembly, is used to provide resistance against rotation of the support frame assembly relative to the base frame assembly.

[0039] In summary, this application provides a step-up trainer. By setting a first distance greater than a second distance, it allows users to perform step-up training by extending their hips upwards to push against their shoulders, increasing the range of motion of the hips, strengthening the stimulation of the gluteal muscles, and meeting the user's training needs. A first adjustment component adjusts the initial vertical height between the shoulders and the bearing plane, making it suitable for users of different heights. By making the top surface of the pedal nearly parallel to the bearing plane, and by using a second adjustment component to adjust the height of the pedal on the base frame, the height difference between the top surface of the pedal and the bearing plane can be changed. This allows the user to perform single-leg step-up training with one leg on the pedal and the other on the bearing plane, adjusting the height difference between the two leg surfaces to increase or decrease, thereby meeting the user's training needs. The system caters to different training needs; it uses a support and adjustment mechanism to adjust the height of the pedals, ensuring stable support for the user's legs; a limiting mechanism with a locking pin allows the pedals to switch between a height-locked and height-adjustable state for convenient training; a second auxiliary component balances the weight of the pedals, facilitating lifting; by ensuring the mass of the second auxiliary component is greater than the mass of the pedals, the pedals are raised relative to the second auxiliary component or always tend to rise, facilitating height adjustment; a sliding mechanism and a locking mechanism allow for easy adjustment of the distance between the swing frame and the base frame assembly, providing greater accommodating users of different heights; and a first auxiliary component assists the user in pushing against their shoulders during step-up training, making it easier for users to initially begin step-up training.

[0053] Reference Appendix Figure 1 To be continued Figure 4, Figure 1 This is a first perspective view of the step-climbing training device of this application; Figure 2 This is a second perspective view of the step-climbing training device of this application; Figure 3 This is the front view of the step-climbing training device of this application; Figure 4 This is a side view of the step trainer of this application; the following is in conjunction with the attached... Figure 1 To be continued Figure 4 Specific embodiments are described below.

[0054] Reference Appendix Figures 1 to 4 This application provides a step-up training device, including a base frame assembly 100, a support frame assembly 200, and a footboard 500. The base frame assembly 100 is disposed on a bearing plane, and the support frame assembly 200 is rotatably disposed on the base frame assembly 100. The support frame assembly 200 has a pivot point 209 and a shoulder support portion 208 rotatably connected to the base frame assembly 100. The vertical distance between the pivot point 209 and the bearing plane is a first distance, and the vertical distance between the shoulder support portion 208 and the bearing plane is a second distance. In the initial position, the second distance is greater than the first distance.

[0055] In some embodiments, the top surface of the pedal 500 is nearly parallel to the bearing plane. The pedal 500 is height-adjustable on the base frame assembly 100. The top surface of the pedal 500 is used to form a height difference relative to the bearing plane. When the first distance is within a preset range, the user steps on the top surface of the pedal 500 with one foot and extends the body diagonally upwards to push against the shoulder and armrest 208 to perform step-climbing training.

[0056] It should be noted that the top surface of pedal 500 being nearly parallel to the bearing plane means that there may be a situation where the top surface of pedal 500 is not parallel to the bearing plane. In this case, the vertical distance from the center point of pedal 500 to the bearing plane is taken as the height difference.

[0057] Reference Appendix Figure 3 and Figure 4 Specifically, the top surface of pedal 500 serves as the stepping plane, parallel to the bearing plane and forming a height difference with it. This provides space for users to squat with one leg while placing their feet on the top surface of pedal 500 and the bearing plane respectively, preventing the user's knee from contacting the bearing plane too early and thus preventing them from continuing to squat and flex and extend their hips.

[0058] Optionally, the top surface of the pedal 500 is equipped with anti-slip stripes to prevent the user's feet from slipping during training.

[0059] The vertical distance between the turning point 209 and the bearing plane is the first distance, and the vertical distance between the shoulder support 208 and the bearing plane is the second distance. In the initial position, the second distance is greater than the first distance.

[0060] It should be noted that the initial position refers to the position of the shoulder support 208 and the pivot point 209 when the user is not training on the machine or when the user is on the machine but not exerting force. The pivot point 209 is fixed relative to the bearing plane, while the shoulder support 208 rotates relative to the pivot point 209 during training. The shoulder support 208 is always higher than the pivot point 209 relative to the bearing plane.

[0061] In some embodiments, the preset range of the first distance is 600mm to 900mm. This preset range refers to the height range of the pivot point 209 relative to the bearing plane, set during the manufacturing of the step-up trainer, being 600mm to 900mm. Preferably, the first distance can be 700mm, 765mm, or 800mm, etc. When the height of the pivot point 209 relative to the bearing plane is lower, the gluteal muscles can be stimulated more effectively when performing step-up training with one leg. For conventional squat trainers, the height of the pivot point 209 relative to the bearing plane is higher. When the user performs squat training by exerting force vertically with both legs relative to the pedal plane, the range of hip opening is fixed and cannot be adjusted as needed. The trainee primarily exerts force with their legs, failing to effectively train the glutes.

[0062] In some embodiments, the distance between the shoulder support 208 and the turning point 209 ranges from 1050 mm to 1400 mm.

[0063] Specifically, when the user extends their hip and exerts force, they push the shoulder support 208 to rotate relative to the pivot point 209 through their shoulders. The straight-line distance between the shoulder support 208 and the pivot point 209 is set to be between 1050mm and 1400mm. Preferably, the distance between the shoulder support 208 and the pivot point 209 can be 1170mm, 1270mm, or 1370mm, etc.

[0064] In some embodiments, during step-up training, the user places one foot on the top surface of the pedal 500, extends the hips diagonally upwards, and pushes against the shoulder support 208 to perform step-up training. The trajectory formed by the shoulder support 208 during the user's training is an arc-shaped trajectory, and the angle between the tangent of the arc-shaped trajectory and the plane where the pedal 500 is located is an acute angle.

[0065] Specifically, the user's leg on the pedal 500 is perpendicular to the top surface of the pedal 500. The user's body extends the hips diagonally upwards, and the shoulder pushes the shoulder arm 208 to rotate around the pivot point 209 to form an arc trajectory. The angle between the tangent of the arc trajectory and the plane where the pedal 500 is located is an acute angle, which causes the user's force direction in the step training to be diagonally upwards and away from the bearing plane.

[0066] An upward-sloping force direction allows for greater hip flexion and extension, more effectively activating the gluteal muscles and thus enhancing the stimulation of these muscles, thereby improving training results. In addition, an upward-sloping force direction can better distribute body weight and training load, reducing the impact on the knee and ankle joints, thereby reducing the risk of joint injury.

[0067] In some embodiments, the shoulder support 208 rotates around a pivot point 209 based on an arc-shaped trajectory, the arc length of which ranges from 600 mm to 1000 mm.

[0068] Specifically, the distance between the shoulder-mounted part 208 and the turning point 209 remains unchanged. The shoulder-mounted part 208 rotates around the turning point 209 based on an arc-shaped trajectory. The arc length of the arc-shaped trajectory ranges from 600mm to 1000mm. Preferably, the arc length of the arc-shaped trajectory can be 750mm, 830mm, 930mm, etc.

[0069] Reference Appendix Figure 2 and Figure 3 In some embodiments, the base frame assembly 100 includes a base frame 101, an upright frame 102, and a load-bearing beam 103. The base frame 101 is laid on a bearing plane, the upright frame 102 is fixed to one end of the base frame 101 and rotatably connected to the support frame assembly 200, and the load-bearing beam 103 is fixed on the base frame 101 and the upright frame 102 to enclose an installation space.

[0070] Specifically, the base frame 101 is laid on a bearing plane, the upright frame 102 is perpendicular to the bearing plane and fixedly connected to the base frame 101, and the end of the upright frame 102 away from the bearing plane is used to rotatably connect with the support frame assembly 200.

[0071] The load-bearing beam 103 is fixedly connected to the base frame 101 and the upright frame 102. The load-bearing beam 103 is used to abut against the support frame assembly 200 to support the support frame assembly 200.

[0072] The load-bearing beam 103, the base frame 101, and the upright frame 102 enclose an installation space. The installation space is used to install the second adjustment component 300 and the resistance component 400, thereby reducing the space occupied by the entire step trainer.

[0073] In some embodiments, a resistance component 400 is disposed on and connected to one side of the support assembly 200, and the resistance component 400 is used to provide resistance to the rotation of the support assembly 200 relative to the base frame assembly 100.

[0074] Specifically, the resistance sources of the resistance component 400 include, but are not limited to, counterweight gravity, motor resistance, magnetic resistance, water resistance, and wind resistance. Those skilled in the art should set the specific structure of the resistance component 400 based on different resistance sources so that the resistance source of the resistance component 400 is the rotation of the support frame component 200 relative to the base frame component 100 to provide resistance.

[0075] Reference Appendix Figure 2 In some embodiments, the resistance component 400 includes a counterweight 401 and a plurality of pulleys 403. The counterweight 401 is connected to the support frame component 200 via a cable, and at least two pulleys 403 are respectively disposed on the base frame component 100 and the support frame component 200.

[0076] Specifically, multiple counterweights 401 are stacked within a counterweight frame 402. Each counterweight 401 has a socket. One end of a cable is inserted into the socket of any counterweight 401, and the other end of the cable passes around at least two pulleys 403 to connect to the support frame assembly 200. The counterweights 401 provide resistance when the support frame assembly 200 rotates relative to the base frame assembly 100. The user adjusts the resistance based on the number of counterweights 401 that the cable moves each time.

[0077] One pulley component 403 is rotatably mounted on the base frame 101 and located within the installation space, while another pulley component 403 is rotatably mounted on the support frame assembly 200. The pulley components 403 are used to change the direction of force to guide the cable transmitting resistance to connect with the support frame assembly 200. The number of pulley components 403 is set based on the number of times the direction of force transmission is changed. Training is conducted by lifting the counterweight 401 based on the support frame assembly 200 to counteract gravity. The pulley components 403 are also used to increase the stroke of the support frame assembly 200, making the placement of the support frame assembly 200 more flexible, or allowing for more freedom in the placement of the counterweight 401.

[0078] Optionally, the load-bearing beam 103 is provided with a clearance opening, which is used for the cable to extend out of the installation space and connect with the support frame assembly 200 after passing around the pulley component 403, so as to avoid the cable from rubbing against the load-bearing beam 103 during the movement.

[0079] In some embodiments, the second adjustment component 300 is rotatably mounted on the base frame assembly 100 and rotatably connected to the pedal 500. The second adjustment component 300 is used to rotate relative to the base frame assembly 100 to push the top surface of the pedal 500 closer to or away from the bearing plane, thereby adjusting the height difference between the top surface of the pedal 500 and the bearing plane.

[0080] Reference Appendix Figure 3 and Figure 4In some embodiments, the second adjustment component 300 includes an adjustment member 301 and a support member 302. The adjustment member 301 is rotatably mounted on the base frame assembly 100 and is rotatably connected to the pedal 500. The two ends of the support member 302 are rotatably connected to the base frame assembly 100 and the pedal 500, respectively.

[0081] Specifically, an extension is fixed at the bottom of the pedal 500. The extension extends vertically from the bottom surface of the pedal 500 towards the bearing plane. The end of the extension away from the pedal 500 is rotatably connected to one end of the support 302. The other end of the support 302 is rotatably connected to the base frame 101 and located in the installation space. One end of the adjusting member 301 is rotatably located between the two ends of the extension. The other end of the adjusting member 301 is rotatably connected to the load-bearing beam 103 and located in the installation space. The adjusting member 301 is located on the side of the support 302 away from the bearing plane.

[0082] The adjusting member 301, the support member 302, and the extension member are made of high-strength steel to stably support the user's legs and prevent bending and deformation. The extension member is used to increase the connection points of the pedal 500 and to keep the top surface of the pedal 500 parallel to the bearing plane. The adjusting member 301 is used to push the pedal 500 away from or closer to the bearing plane while rotating relative to the load-bearing beam 103, thereby changing the height difference between the top surface of the pedal 500 and the bearing plane. The support member 302 is used to assist the adjusting member 301 in adjusting the distance between the pedal 500 and the bearing plane, and to support the pedal 500 and prevent the extension member from flipping relative to the adjusting member 301.

[0083] Optionally, the adjusting member 301 further includes two connecting parts and a rotating part. The two connecting parts are arranged parallel to each other on both sides of the extension member and are rotatably connected to each other. The rotating part is fixed between the two connecting parts and is used to rotatably connect with the load-bearing beam 103. The two connecting parts and the rotating part form a stable I-beam structure to stabilize the height difference between the top surface of the adjusting pedal 500 and the bearing plane.

[0084] In some embodiments, the height of the top surface of the pedal 500 relative to the bearing plane is set in the range of 200mm to 500mm.

[0085] Optionally, the pedal 500 is fixedly mounted on the base frame assembly 100, and its height relative to the bearing plane is set in the range of 200mm to 500mm; preferably, the pedal height can be 200mm, 300mm, 400mm, 500mm, etc.

[0086] Optionally, the pedal 500 is adjustablely mounted on the base frame assembly 100 via a second adjustment component, and its height relative to the bearing plane is adjustable via the second adjustment component, with an adjustment range of 200mm to 500mm; preferably, the adjustment range of the pedal can be 200mm, 300mm, 400mm, 500mm, etc.

[0087] Reference Appendix Figure 3 In some embodiments, the second adjustment component 300 further includes a limiting member 303 and a pin 304. The limiting member 303 is fixed on the base frame assembly 100 and has multiple locking points. The pin 304 passes through the adjustment member 301 and engages with any locking point to lock or release the relative rotation between the adjustment member 301 and the base frame assembly 100.

[0088] Specifically, the limiting member 303 is a plate-shaped component fixed on the load-bearing beam 103. The limiting member 303 has multiple limiting holes as locking points. The outer diameter of the pin 304 matches the inner diameter of the limiting hole, so as to pass through the adjusting member 301 and extend into or out of any limiting hole, thereby achieving the purpose of locking or releasing the relative rotation between the adjusting member 301 and the load-bearing beam 103, and thus keeping the pedal 500 at a certain height for training.

[0089] Optionally, the limiting member 303 is a ratchet component fixed on the load-bearing beam 103. The limiting member 303 has multiple limiting grooves on its edge as locking points. The outer diameter of the pin 304 matches the inner diameter of the limiting groove, so as to pass through the adjusting member 301 and extend into or out of any limiting groove, thereby achieving the purpose of locking or releasing the relative rotation between the adjusting member 301 and the load-bearing beam 103, and thus keeping the pedal 500 at a certain height for training.

[0090] Reference Appendix Figure 3 and Figure 4 In some embodiments, the second adjustment assembly 300 further includes a second auxiliary member 305, which is disposed opposite to the pedal 500 at both ends of the adjustment member 301. The rotatable connection between the adjustment member 301 and the base frame assembly 100 is located between the pedal 500 and the second auxiliary member 305. The mass of the second auxiliary member 305 is greater than the mass of the pedal 500, and it is used to press down one end of the adjustment member 301 to make the pedal 500 move away from the bearing plane.

[0091] Specifically, the second auxiliary component 305 is located at the other end of the adjusting component 301 relative to the pedal 500. The second auxiliary component 305 is located in the installation space. Based on the rotational connection between the adjusting component 301 and the load-bearing beam 103, the second auxiliary component 305 is used to balance the weight of the pedal 500, making it easier for the user to adjust the lifting of the pedal 500 and move the pedal 500 away from the load-bearing plane without too much effort.

[0092] The second auxiliary component 305 is made to have a mass greater than that of the pedal 500. When the user pulls out the pin 304 from the locking point to release the relative rotation of the adjusting component 301 and the load-bearing beam 103, the second auxiliary component 305 presses down on one end of the adjusting component 301 based on its own weight, causing the adjusting component 301 to rotate relative to the load-bearing beam 103. This causes the pedal 500 to automatically rise or have an upward tendency. The user only needs to insert the pin 304 into another locking point at a suitable height to lock the relative rotation of the adjusting component 301 and the load-bearing beam 103, thus stabilizing the pedal 500 at a certain height for single-leg step training.

[0093] It should be noted that, based on the dividing point of the rotational connection between the adjusting component 301 and the load-bearing beam 103, in order to make the travel of the pedal 500 greater and thus create a greater height difference relative to the bearing plane, the lever arm length of the adjusting component 301 near the pedal 500 is greater than the lever arm length of the end near the second auxiliary component 305. At this time, the mass of the second auxiliary component 305 should be set to be much greater than the mass of the pedal 500, so as to achieve the purpose that the torque near the end of the second auxiliary component 305 is greater than the torque near the end of the pedal 500, thereby causing the pedal 500 to automatically rise upward or have an upward tendency.

[0094] Reference Appendix Figures 2 to 4 In some embodiments, the support frame assembly 200 includes a swing frame 201 and a first adjustment assembly. The first adjustment assembly is used to adjust the initial vertical height of the shoulder support 208 and the bearing plane. The shoulder support 208 and the pivot point 209 are located on opposite sides of the first adjustment assembly. The swing frame 201 is rotatably mounted on the base frame assembly 100.

[0095] Specifically, one end of the swing frame 201 is rotatably mounted on the upright frame 102 based on the pivot point 209, and the other end of the swing frame 201 extends obliquely upward away from the pivot point 209 before being connected to the shoulder support 208. The oblique upward extension of the swing frame 201 is used to increase the height of the end of the swing frame 201 relative to the end away from the upright frame 102, so that the shoulder support 208 is higher than the pivot point 209, and the shoulder support 208 can rotate around the pivot point 209.

[0096] Reference Appendix Figures 2 to 4In some embodiments, the first adjustment component includes a telescopic sleeve 202, a sliding member 203, and a locking member 204. The telescopic sleeve 202 is disposed on the swing frame 201 and swings relative to the base frame assembly 100 with the swing frame 201. The shoulder support 208 and the pivot point 209 are located opposite each other on both sides of the telescopic sleeve 202. The sliding member 203 is slidably disposed inside the telescopic sleeve 202. The end of the sliding member 203 away from the swing frame 201 is used to abut against the base frame assembly 100. Both the telescopic sleeve 202 and the sliding member 203 are provided with matching limiting holes. The locking member 204 is used to insert into the limiting holes to lock or release the relative sliding of the telescopic sleeve 202 and the sliding member 203.

[0097] Specifically, the telescopic sleeve 202 is hollow inside and is rotatably mounted on the swing frame 201. The telescopic sleeve 202 is used to follow the swing frame 201 in rotating relative to the upright frame 102 and is used to connect the resistance source, thereby providing resistance to the rotation of the swing frame 201 relative to the upright frame 102. The shoulder support 208 and the pivot point 209 are located on opposite sides of the telescopic sleeve 202.

[0098] One end of the sliding member 203 is slidably disposed inside the telescopic sleeve 202, and the other end of the sliding member 203 is used to abut against the load-bearing beam 103. The sliding member 203 is used to slide relative to the telescopic sleeve 202, thereby changing the distance between the swing frame 201 and the pedal 500, thus making it more accommodating to users of different heights.

[0099] The pulley 403 on the support assembly 200 is rotatably located at the end of the sliding member 203 away from the swing frame 201. The cable connecting the counterweight 401 passes through the clearance on the load-bearing beam 103 and then passes around the pulley 403 on the sliding member 203 and connects to the sliding member 203. The pulley 403 on the sliding member 203 is used to cooperate with the pulley 403 on the base frame assembly 100 through the cable to stabilize the movement of the swing frame 201 and prevent the swing frame 201 from swaying in a direction parallel to the bearing plane.

[0100] The locking component 204 includes, but is not limited to, screws, bolts, and pins. The locking component 204 is inserted into the telescopic sleeve 202. The locking component 204 passes through the telescopic sleeve 202 and abuts against the sliding component 203, or passes through multiple locking holes on the sliding component 203, so as to lock the relative sliding of the telescopic sleeve and the sliding component 203. Before training, the user should use the locking component 204 to adjust the length of the sliding component 203 relative to the telescopic sleeve 202 based on his / her own height, so as to adjust the distance between the swing frame 201 and the pedal 500.

[0101] In some embodiments, the relative sliding displacement range between the slider 203 and the telescopic sleeve 202 is 0 to 100 mm; preferably, the relative displacement can be 30 mm, 50 mm or 80 mm, etc.

[0102] Reference Appendix Figure 2 and Figure 3 In some embodiments, a first auxiliary member 600 is disposed at the end of the swing frame 201 that is relatively far away from the shoulder support 208. The first auxiliary member 600 is used to assist the user in pushing against the shoulder support 208 so as to drive the swing frame 201 to rotate relative to the base frame assembly 100.

[0103] Specifically, the first auxiliary component 600 is a counterweight. During training, when the user pushes against the shoulder section 208 and rotates relative to the pivot point 209, the first auxiliary component 600 moves synchronously at the other end of the pivot point 209 relative to the shoulder section 208 to help the user push against the shoulder section 208, making it convenient for the user to start step-up training or to do light-weight step-up training or rehabilitation training.

[0104] Reference Appendix Figures 2 to 4 In some embodiments, the support frame assembly 200 further includes a handrail 205, a shoulder pad 206, and a buffer 207. The handrail 205 is fixed on the swing frame 201, the shoulder pad 206 is disposed on the swing frame 201, and the shoulder pad 206 and the pivot point 209 on the swing frame 201 are located opposite each other at both ends of the telescopic sleeve 202. The buffer 207 is disposed between the sliding member 203 and the base frame assembly 100.

[0105] Specifically, the handrail 205 is fixed on the swing frame 201 and is inclined on the swing frame 201, so that the user can hold the handrail 205 with both hands during training.

[0106] Shoulder pad 206 is fixed on the swing frame 201 at the end away from the upright frame 102, that is, the shoulder pad 206 is fixed at the shoulder support 208. Based on the motion of the user carrying the swing frame 201 and rotating relative to the upright frame 102, the impact force caused by the contact between the sliding member 203 and the load-bearing beam 103 will be transmitted to the user's shoulder through the swing frame 201. Shoulder pad 206 is used to alleviate the impact force transmitted to the user's shoulder.

[0107] The buffer 207 includes, but is not limited to, rubber, sponge and spring. The buffer 207 is provided on the sliding member 203 or on the load-bearing beam 103, so that the buffer 207 is located between the sliding frame and the load-bearing beam 103, so as to reduce the impact force caused by the contact between the sliding member 203 and the load-bearing beam 103, thereby reducing noise and extending the service life of the instrument.

[0108] In some embodiments, the initial vertical height between the shoulder support 208 and the bearing plane ranges from 1180 mm to 1340 mm. Preferably, the initial vertical height can be 1200 mm, 1280 mm, or 1320 mm, etc.

[0109] It should be noted that the initial vertical height refers to the vertical distance between the position of the bottom surface of the shoulder support 208 away from the bearing plane and the bearing plane when the user is not training on the machine or when the user is on the machine but not exerting force. The distance ranges from 1180mm to 1340mm.

[0110] When a shoulder pad 206 is provided at the shoulder support 208, the initial vertical height refers to the vertical distance between the position of the bottom surface of the shoulder pad 206 away from the bearing plane and the bearing plane when the user is not training on the machine, or when the user is on the machine but not exerting force. The distance ranges from 1180mm to 1340mm.

[0111] When using the step trainer, the user first places one foot on the pedal 500 and the other foot on the support surface to perform step training, adjusting the height of the pedal 500 based on the hip flexion and extension sensation.

[0112] When adjusting the height of the pedal 500, the adjusting member 301 is released from relative rotation with the load-bearing beam 103 by pulling out the pin 304. The pedal 500 at the other end of the adjusting member 301 is raised or lowered by pushing the second auxiliary member 305 to press down or lift one end of the adjusting member 301, until the height difference between the top surface of the pedal 500 and the load-bearing plane is appropriate. Then, the adjusting member 304 is inserted into the locking point to lock the relative rotation between the adjusting member 301 and the load-bearing beam 103, so that the pedal 500 is kept at a suitable height for training.

[0113] After the height of the pedal 500 is adjusted, the user steps on the pedal 500 and carries the swing frame 201 on their shoulder, adjusting the distance between the pedal 500 and the swing frame 201 according to their own height.

[0114] When adjusting the distance between the pedal 500 and the swing frame 201, the user pushes the shoulder-carrying part 208 with their shoulder and pulls out the locking piece 204 with their other hand to release the relative sliding of the sliding piece 203 and the telescopic sleeve 202. One end of the sliding piece 203 rests on the load-bearing beam 103. The user pushes the swing frame 201 by bending and stretching their body, causing the telescopic sleeve 202 to rotate relative to the upright frame 102 until the distance between the pedal 500 and the swing frame 201 is appropriate. Then, the locking piece 204 is inserted into the telescopic sleeve 202 to cooperate with the sliding piece 203 to lock the relative sliding of the sliding piece 203 and the telescopic sleeve 202, so that the swing frame 201 is kept at a suitable height for training.

[0115] After the above adjustments are completed, when using the step trainer for step training, the user extends their hip by stepping on the top surface of the pedal 500 with one leg, causing their center of gravity to move diagonally upward away from the load-bearing plane. At the same time, the user's shoulder pushes against the resistance of the shoulder support 208 against the resistance of the frame assembly 200, and the shoulder support 208 rotates around the pivot point 209 based on an arc trajectory to stimulate the gluteal and leg muscles. During the training, the user can alternate between one leg and another to perform the step-up movement. After one foot is on the pedal 500 and the hip joint extension and flexion movement is completed, the user first lowers one foot to the load-bearing plane, then lowers the other foot, and so on, repeating the cycle, just like stepping on stairs, to achieve the purpose of training the gluteal muscles.

[0116] The user squats down to make the slider 203 contact the load-bearing beam 103, and continues to squat down to make the shoulder leave the shoulder pad 206, and moves the foot on the pedal 500 to the load-bearing plane to complete the step training.

[0117] This application provides a step-up trainer. By setting a first distance greater than a second distance, it allows the user to perform step-up training by extending their hips diagonally upwards to push against the shoulder support 208, increasing the range of motion of the hips, strengthening the stimulation of the gluteal muscles, and meeting the user's training needs. A first adjustment component adjusts the initial vertical height between the shoulder support 208 and the bearing plane, accommodating users of different heights. A second adjustment component 300, mounted on the base frame 100, adjusts the height difference between the top surface of the pedal 500 and the bearing plane, allowing the user to perform single-leg step-up training with one leg on the pedal 500 and the other on the bearing plane. The height difference between the two leg surfaces can be adjusted to increase or decrease, thus meeting different training needs. A support member 302 assists the adjustment member 301 in adjusting the height of the pedal 500. The footrest 500 provides stable support for the user's legs. A limiting component 303, in conjunction with a pin 304, allows the footrest 500 to switch between a height-locked state and a height-adjustable state, facilitating user training. A second auxiliary component 305 balances the weight of the footrest 500, making it easier for the user to lift it. By ensuring the mass of the second auxiliary component 305 is greater than the mass of the footrest 500, the footrest 500 is raised relative to the second auxiliary component 305, or always tends to rise, facilitating height adjustment. The cooperation of the sliding component 203 and the locking component 204 allows for easy adjustment of the distance between the swing frame 201 and the base frame assembly 100, providing greater accommodating users of different heights. A first auxiliary component 600 assists the user in pushing against the shoulder support 208 during step-climbing training, making it easier for the user to initially begin step-climbing training.
