Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, specifically to a mountaineering machine. Background Technology

[0002] A stair climber is a fitness device that simulates mountain climbing, exercising lower limb muscles and improving cardiovascular function by mimicking the motion of climbing. When using a stair climber, each foot rests on one of the two foot pedals. Due to the exertion of force during movement, the outer edges of the foot pedals often bear greater stress. The foot pedals are slidably connected to the stair climber's sliding support. Over time, this greater stress on the outer edges of the foot pedals is transmitted to the sliding support, leading to increased wear and tear on the corresponding area. This can compromise structural safety and may even cause obstruction or jamming. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a climbing machine that can ensure that the sliding support connected to the foot pedal is subjected to balanced force, thereby ensuring reliable sliding of the foot pedal.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A climbing machine includes a frame, two pedal assemblies, a belt assembly, and at least one resistance element for providing movement resistance to the pedal assemblies. The frame has sliding supports corresponding to each pedal assembly, the sliding supports being parallel and spaced apart. Each pedal assembly is slidably connected to its corresponding sliding support. The belt assembly is positioned between the two sliding supports and includes a belt and two pulleys. The two pulleys are spaced apart, and the line connecting the two pulleys is parallel to the sliding support. The pulleys are rotatably connected to the frame, and the belt connects the two pulleys. One pedal assembly is connected to a transmission surface on one side of the belt pulley, and the other pedal assembly is connected to a transmission surface on the other side of the pulley. The two pedal assemblies move synchronously but in opposite directions.

[0005] With the above setup, by placing a belt assembly between the two sliding supports and connecting the two foot pedal assemblies to the transmission surfaces of the belt in different transmission directions, the belt is tensioned due to the connection pulleys. When the user applies an outward force to the foot pedal assembly, the belt applies force to the inward side of the foot pedal assembly. Furthermore, the force applied by the belt can be adaptively adjusted; that is, the greater the outward force applied by the user, the more the belt will be stretched, and the greater the belt tension will be. By balancing the force on the foot pedal assembly through the belt, the foot pedal assembly slides more evenly on the sliding supports, thus ensuring reliable sliding of the foot pedal assembly and guaranteeing the structural safety and service life of the sliding supports.

[0006] The line connecting the two drive surfaces of the belt is parallel to the line connecting the two sliding supports. With this arrangement, the belt is less likely to twist or come off the pulley.

[0007] The frame is equipped with a tensioning assembly to prevent the belt from becoming loose. The tensioning assembly is designed to ensure that the belt assembly functions properly.

[0008] The tensioning assembly includes a connecting seat, at least two tensioning screws, at least two tensioning nuts, and at least two springs. Any one of the pulleys is rotatably connected to the connecting seat. Each tensioning screw, nut, and spring corresponds to a separate spring. The tensioning screw passes sequentially through the connecting seat, spring, and frame before being threaded into the tensioning nut. The spring is compressed and positioned between the connecting seat and the frame. This configuration of the tensioning assembly results in a simple structure and high reliability.

[0009] The foot pedal assembly includes a pedal and a sliding seat. The sliding seat is slidably connected to a sliding bracket and is connected to a corresponding transmission surface. A connecting plate is provided at the bottom of the pedal. One end of the connecting plate is rotatably connected to the sliding seat, and the other end of the connecting plate has several first adjustment holes. The sliding seat has first pin holes that mate with the first adjustment holes. The first adjustment holes and the first pin holes are connected by a pin. This configuration allows the pedal angle to be adjusted to suit different users and usage needs, and the structure is simple and adjustment is convenient and quick.

[0010] The sliding seat has an extension rod on the side near the belt assembly. The end of the extension rod has a first clamping plate and a second clamping plate. The first clamping plate is fixedly connected to the end of the extension rod, and the first and second clamping plates are bolted together to clamp the corresponding transmission surface. The first and / or second clamping plates have ribs for anti-slip purposes. This configuration ensures reliable connection of the sliding seat to its corresponding transmission surface and prevents the belt from easily twisting.

[0011] Each foot pedal assembly corresponds to at least one resistance element, which is an elastic cord. A roller corresponding to each foot pedal assembly is rotatably connected to the frame, and the roller is located above the foot pedal assembly. A cord connection point is provided on the frame below the roller; one end of the elastic cord is connected to the cord connection point, and the other end of the elastic cord passes around the roller and connects to the corresponding foot pedal assembly. This arrangement allows for a longer elastic cord length, resulting in less elasticity loss over long-term use and thus extending its service life.

[0012] The frame includes a first frame and a second frame. The foot pedal assembly, belt assembly, resistance element, and sliding bracket are all mounted on the first frame. The second frame is detachably connected to the first frame, and the first and second frames are arranged at an angle. This frame structure is simple and facilitates storage and transportation.

[0013] The first frame is equipped with an adjusting arm and a pressure rod, and the adjusting arm has several second adjusting holes. The second frame is equipped with a pressure-bearing seat, a pressure-bearing platform, and second pin holes that mate with the second adjusting holes. The second adjusting holes and second pin holes are connected by a pin. The pressure-bearing seat has an arc-shaped groove that fits the outer wall of the pressure rod, and the pressure rod abuts against the arc-shaped groove. The pressure-bearing platform abuts against the first frame. With this configuration, the tilt angle of the first frame can be adjusted within a certain range to meet the needs of different users, and the adjustment is simple. The cooperation of the arc-shaped groove and the pressure rod ensures that the first frame is always reliably supported, which is beneficial to structural stability.

[0014] The frame is also equipped with a telescopic frame, and the telescopic frame has handrails. The telescopic frame is designed to facilitate the adjustment of the handrail height, and the handrails make it easier for users to exercise using the stair climber.

[0015] By adopting the above solution, a belt assembly is installed between the two sliding supports, and the two foot pedal assemblies are connected to the transmission surfaces of the belt in different transmission directions. The belt is tensioned due to the connection pulleys. When the user applies an outward force to the foot pedal assembly, the belt applies force to the inward side of the foot pedal assembly. Furthermore, the force applied by the belt can be adaptively adjusted; that is, the greater the outward force applied by the user, the more the belt is stretched, and the greater the belt tension. The belt balances the force on the foot pedal assembly, allowing for more even sliding of the foot pedal assembly on the sliding supports, thus ensuring reliable sliding of the foot pedal assembly and guaranteeing the structural safety and service life of the sliding supports.

Detailed Implementation

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0019] like Figure 1-11 As shown, this utility model discloses a climbing machine, which includes a frame, two foot pedal assemblies, a belt assembly, and at least one resistance element 51.

[0020] The frame includes a first frame 10 and a second frame 20, which are detachably connected to the first frame 10. The first frame 10 and the second frame 20 are arranged at an angle. As a preferred connection method, the first frame 10 is provided with an adjusting arm 11 and a pressure rod 12 (circular tube or cylinder). The adjusting arm 11 has several second adjusting holes 13. The second frame 20 is provided with a pressure seat 22, a pressure platform 21, and second pin holes 23 that mate with the second adjusting holes 13. The pressure platform 21 abuts against the top of the first frame 10. The second adjusting holes 13 are connected to the second pin holes 23 via a first pin 14. By passing the first pin 14 through different second adjusting holes 13, the inclination of the first frame 10 can be adjusted. An arc-shaped groove 24 adapted to the outer wall of the pressure rod 12 is provided on the pressure seat 22. The pressure rod 12 presses against the arc-shaped groove 24 to ensure that the pressure rod 12 can reliably press against the pressure seat 22 when the first frame 10 has different inclinations, thereby ensuring structural safety.

[0021] The second frame 20 is also equipped with a telescopic frame 25, and the telescopic frame 25 is equipped with a handrail 26. The telescopic frame 25 extends and retracts relative to the second frame 20 to adjust the height of the handrail 26. The telescopic frame 25 can be locked and connected by bolts, pipe buckles or other means.

[0022] The first frame 10 is equipped with sliding brackets 15 that correspond one-to-one with the foot pedal components. The sliding brackets 15 can be the main support of the first frame 10 or can be set separately. The former is preferred, as it simplifies the structure. The two sliding brackets 15 are parallel to each other and spaced apart.

[0023] The foot pedal assembly includes a pedal 31 and a sliding seat 32. The sliding seat 32 is slidably connected to a sliding bracket 15. A connecting plate 33 is fixedly installed at the bottom of the pedal 31. One end of the connecting plate 33 (corresponding to the tip of the pedal 31) is rotatably connected to the sliding seat 32. The other end of the connecting plate 33 is provided with several first adjustment holes 34. The sliding seat 32 is provided with first pin holes 35 that mate with the first adjustment holes 34. The first adjustment holes 34 and the first pin holes 35 are connected by a second pin 36. The second pin 36 passes through different first adjustment holes 34 to adjust the angle of the pedal 31.

[0024] The belt assembly is positioned between two sliding supports 15. The belt assembly includes a belt 41 and two pulleys. For ease of distinction, the two pulleys are designated as the first pulley 42 and the second pulley 43. The first pulley 42 and the second pulley 43 are spaced apart, and the line connecting the first pulley 42 and the second pulley 43 is parallel to the sliding support 15. The first pulley 42 is rotatably connected to the upper end of the first frame 10, and a tensioning assembly is provided at the lower end of the first frame 10 to connect to the second pulley 43. Alternatively, the tensioning assembly can be located at the upper end of the first frame 10, with the first pulley 42 connected to the tensioning assembly, and the second pulley 43 rotatably connected to the lower end of the first frame 10.

[0025] Specifically, the tensioning assembly includes a connecting seat 16, at least two tensioning screws 17, at least two tensioning nuts 18, and at least two springs 19. The second pulley 43 is rotatably connected to the connecting seat 16. The tensioning screws 17, tensioning nuts 18, and springs 19 correspond one-to-one. The tensioning screws 17 pass through the connecting seat 16, springs 19, and frame in sequence and are threadedly connected to the tensioning nuts 18. The tensioning screws 17 and tensioning nuts 18 are tightened so that the springs 19 are compressed and positioned between the connecting seat 16 and the frame.

[0026] The belt 41 connects and tensions the first pulley 42 and the second pulley 43. The transmission surface of the belt 41 on one side of the pulley is the first transmission surface 44, and the transmission surface on the other side of the pulley is the second transmission surface 45. The transmission directions of the first transmission surface 44 and the second transmission surface 45 are opposite, and the line connecting the first transmission surface 44 and the second transmission surface 45 is parallel to the line connecting the two sliding supports 15. The sliding seat 32 corresponding to one foot pedal assembly is connected to the first transmission surface 44, and the sliding seat 32 corresponding to the other foot pedal assembly is connected to the second transmission surface 45. In this way, the two foot pedal assemblies can move synchronously in opposite directions.

[0027] The sliding seat 32 is connected to the corresponding transmission surface as follows: An extension rod 37 is provided on the side of the sliding seat 32 near the belt assembly. A first clamping plate 38 and a second clamping plate 39 are provided at the end of the extension rod 37. The first clamping plate 38 is fixedly connected to the end of the extension rod 37, and the first clamping plate 38 and the second clamping plate 39 are bolted together. By placing the first clamping plate 38 and the second clamping plate 39 on the inner and outer surfaces of the transmission surface respectively, and then tightening the bolts, the corresponding transmission surface can be clamped. Ribs can be provided on the first clamping plate 38 and / or the second clamping plate 39 to prevent slippage. The length direction of the ribs is perpendicular to the transmission direction of the transmission surface.

[0028] The resistance element 51 is used to provide movement resistance for the pedal assembly. Specifically, in this case, each pedal assembly corresponds to at least one resistance element 51, and preferably the resistance element 51 is an elastic rope. A roller 52 corresponding to each pedal assembly is rotatably connected at the upper end of the first frame 10 and above the pedal assembly. A rope connection point 53 is provided at the middle or lower end of the first frame 10 (at least below the roller 52). One end of the elastic rope is connected to the rope connection point 53, and the other end of the elastic rope passes around the roller 52 and is connected to the sliding seat 32 of the corresponding pedal assembly.

[0029] The key to this invention lies in the use of a belt assembly between the two sliding supports 15, with each foot pedal assembly connected to a transmission surface on the belt 41 in a different direction. The belt 41 is tensioned due to its connection to the pulleys. When the user applies an outward force to the foot pedal assembly, the belt 41 applies force to the inward side of the assembly. Furthermore, the force applied by the belt 41 is adaptively adjustable; the greater the outward force applied, the more the belt 41 is stretched, resulting in greater tension. By balancing the force on the foot pedal assembly through the belt 41, the sliding of the foot pedal assembly on the sliding support 15 becomes more even, ensuring reliable sliding and guaranteeing the structural safety and service life of the sliding support 15.

[0030] The above description is merely an embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
