Description

Technical Field

[0001] This utility model belongs to the field of mountaineering machine technology, specifically relating to a mountaineering machine equipped with an angle adjuster. Background Technology

[0002] Currently, a type of stair climber has appeared on the market that allows people to simulate mountain climbing or stair climbing movements. Existing stair climbers mainly consist of a frame supported on the ground, with two guide rails (left and right) at a certain angle to the ground. Each guide rail has a set of pedal assemblies. The two sets of pedal assemblies are connected by a traction rope that passes around a traction pulley on the stair climber frame, allowing them to slide back and forth at a certain angle, thus simulating mountain climbing movements. However, the tilt angle of the two guide rails in existing stair climbers is fixed and cannot be adjusted, preventing them from meeting the fitness needs of a wider range of users. Therefore, further improvements are needed. Utility Model Content

[0003] This invention provides a stair climber equipped with an angle adjuster, aiming to solve the problem that the tilt angles of the two guide rails on existing stair climbers are fixed and cannot be adjusted, which prevents the stair climber from meeting the fitness needs of more users.

[0004] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0005] A climbing machine equipped with an angle adjuster includes:

[0006] The base frame is equipped with support parts for supporting the ground;

[0007] A guide frame, the lower end of which is hinged to the rear end of the base frame, and the upper end of which extends towards the upper front end of the base frame; the guide frame is provided with left and right guide rails and left and right sets of pedal assemblies, the two sets of pedal assemblies being slidably mounted on the two guide rails respectively; the guide frame is also provided with a traction rope pulley and a traction rope located between the two sets of pedal assemblies and passing around the traction rope pulley; and,

[0008] An angle adjuster is disposed between the lower end of the guide frame and the rear end of the base frame and is used to adjust and lock the tilt angle of the guide frame relative to the base frame.

[0009] A further embodiment: The angle adjuster includes a ratchet connected to the lower end of the guide frame and a pawl connected to the rear end of the base frame. An elastic element is provided between the pawl and the base frame to drive the pawl to engage with the ratchet. The pawl adjusts and locks the tilt angle of the guide frame relative to the base frame by engaging with different ratchet teeth on the ratchet.

[0010] Based on the above technical solution: by setting an angle adjuster including a ratchet and a pawl, the pawl can adjust and lock the tilt angle of the guide frame relative to the base frame by cooperating with different ratchet teeth on the ratchet, so that it has more tilt angle adjustment stops and is easier to adjust. The pawl abuts in the ratchet tooth groove, thereby preventing the ratchet from rotating, and thus preventing the climbing frame from rotating relative to the base frame. By setting an elastic element, the pawl is kept in cooperation with the ratchet to prevent the two from disengaging, making the climbing machine more stable during use.

[0011] A further embodiment: the lower end of the guide frame is hinged to the rear end of the base frame via a first hinge shaft, and the ratchet is coaxially arranged with the first hinge shaft and rotates synchronously with the guide frame.

[0012] A further embodiment: a locking pin is detachably provided between the lower end of the guide frame and the rear end of the base frame.

[0013] Based on the above technical solution: by setting a locking pin combined with a ratchet and pawl assembly, the mountaineering machine is more stable during use; when adjusting the tilt angle of the guide frame, the locking pin can be removed for adjustment.

[0014] A further embodiment: the pawl is rotatably connected to the base frame via a second hinge shaft, and the pawl and the second hinge shaft are rotatably connected synchronously.

[0015] A further embodiment: the elastic element is a torsion spring, which is sleeved on the second hinge shaft and located between the pawl and the base frame.

[0016] Based on the above technical solution: the above setting allows the user to disengage the pawl from the ratchet wheel by moving it, thereby adjusting the tilt angle of the guide frame relative to the base frame. When the pawl is released, it will re-engage in the ratchet groove on the ratchet wheel under the reset action of the torsion spring.

[0017] A further solution: The base frame is provided with a lever, which is fixedly connected to the second hinge shaft.

[0018] Based on the above technical solution: by setting the lever part to be fixedly connected to the second hinge shaft, the user can easily disengage the pawl from the ratchet by moving the lever part, thus facilitating user adjustment.

[0019] A further embodiment: The base frame includes two supports arranged side by side on the left and right, and a lower connecting frame located between the rear ends of the two supports. Each support is provided with a hinge groove extending in the front-to-back direction.

[0020] The guide frame includes two guide rail frames arranged side by side on the left and right, and an upper connecting frame located between the upper parts of the two guide rail frames. The two guide rails are respectively located on the two guide rail frames; the two guide rail frames are hinged one-to-one in the two hinge slots.

[0021] Based on the above technical solution: by setting two guide rails that are hinged one-to-one in two hinge slots, both guide rails are folded into their corresponding hinge slots when the machine is folded. This not only makes the mountaineering machine more stable when folded, but also makes it smaller in size and easier to store.

[0022] A further solution: Each guide rail frame and its corresponding bracket are provided with two sets of angle adjusters, and the two sets of angle adjusters are respectively located on the left and right sides of the guide rail frame;

[0023] All the ratchet wheels are coaxially arranged, and all the pawls are coaxially arranged.

[0024] Based on the above technical solution: the above settings make the connection between the guide frame and the base frame more stable and the left and right forces balanced; and all angle adjusters can synchronously adjust the tilt angle of the guide frame relative to the base frame, which is convenient for user operation.

[0025] A further embodiment: The upper connecting frame is provided with a handrail frame, the lower end of the handrail frame is hinged to the upper connecting frame, and a locking element is detachably provided between the handrail frame and the upper connecting frame.

[0026] Based on the above technical solution: by setting up a handrail frame, users can maintain balance by gripping the handrail frame with both hands when simulating mountain climbing movements. By detachably setting a locking device between the handrail frame and the upper connecting frame, the handrail frame is more stable when used in mountain climbing mode. At the same time, by removing the locking device, the handrail frame can be switched to a folding state, making the entire mountain climbing machine smaller and more convenient for packaging and transportation.

[0027] The beneficial effects of this utility model are as follows:

[0028] This utility model of a climbing machine features a base frame for ground support and a guide frame for users to place their feet on two sets of pedal assemblies, allowing them to slide back and forth along the guide frame to simulate climbing motions. An angle adjuster is located between the lower end of the guide frame and the rear end of the base frame to adjust and lock the tilt angle of the guide frame relative to the base frame. This allows the guide frame to have a gentler or steeper slope, or to fold together with the base frame, making it convenient for different users to adjust the tilt angle of the guide frame according to their fitness needs, thus broadening its applicability.

Detailed Implementation

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. It should be understood that the specific embodiments described herein are merely for explaining the present utility model and are not intended to limit the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0036] like Figures 1 to 3 As shown, this embodiment provides a climbing machine equipped with an angle adjuster, including:

[0037] The base frame 1 is provided with a support part for supporting itself on the ground; the support part is specifically the lower end face of the base frame 1;

[0038] A guide frame 2, the lower end of which is hinged to the rear end of the base frame 1, and the upper end of which extends towards the upper front end of the base frame 1; the guide frame 2 is provided with two guide rails 22 (left and right) and two sets of pedal assemblies 7 (left and right), the two sets of pedal assemblies 7 being slidably mounted on the two guide rails 22 respectively; the guide frame 2 is also provided with a traction rope wheel 27 and a traction rope 26 located between the two sets of pedal assemblies 7 and passing around the traction rope wheel 27; and,

[0039] An angle adjuster is disposed between the lower end of the guide frame 2 and the rear end of the base frame 1 and is used to adjust and lock the tilt angle of the guide frame 2 relative to the base frame 1.

[0040] In some specific implementations, such as Figures 1 to 3 As shown, the angle adjuster includes a ratchet 3 connected to the lower end of the guide frame 2 and a pawl 4 connected to the rear end of the base frame 1. An elastic element is provided between the pawl 4 and the base frame 1 to drive the pawl 4 to engage with the ratchet 3. The ratchet 3 has several ratchet teeth 31, and a ratchet groove 32 is provided between each pair of adjacent ratchet teeth 31. The pawl 4 adjusts and locks the tilt angle of the guide frame 2 relative to the base frame 1 by engaging with different ratchet teeth 31 on the ratchet 3. Specifically, when the guide frame 2 is rotated clockwise to increase its tilt angle, the user can rotate the guide frame 2 smoothly. When the user needs to rotate the guide frame 2 counterclockwise to decrease its tilt angle, the user first needs to disengage the pawl 4 from the ratchet 3, and then rotate the guide frame 2 counterclockwise to adjust its tilt angle. After adjustment, the pawl 4 is released, and under the action of the elastic element, the pawl 4 re-engages with the ratchet 3, thereby locking the tilt angle of the guide frame 2 relative to the base frame 1.

[0041] In some specific embodiments, the lower end of the guide frame 2 is hinged to the rear end of the base frame 1 via a first hinge shaft 9, and the ratchet 3 is coaxially arranged with the first hinge shaft 9 and rotates synchronously with the guide frame 2.

[0042] The ratchet 3 is fixedly connected to the guide frame 2. Specifically, the ratchet 3 is fixedly connected to the guide frame 2 by a number of bolts 33 or screws.

[0043] In some specific implementations, such as Figure 1 As shown, to enhance the stability of the climbing machine during use, a locking pin is detachably provided between the lower end of the guide frame and the rear end of the base frame. Specifically, both the lower end of the guide frame and the rear end of the base frame have insertion holes for the locking pin. The locking pin, by inserting into the two insertion holes and in conjunction with the ratchet and pawl assembly, makes the climbing machine more stable during use. When the user needs to adjust the tilt angle of the guide frame, the locking pin must first be removed.

[0044] The pawl 4 is rotatably connected to the base frame 1 via a second hinge shaft 5, and the pawl 4 and the second hinge shaft 5 are rotatably connected synchronously. Specifically, the pawl 4 has a connecting portion at one end and a pawl tooth 41 portion at the other end. The connecting portion is rotatably connected to the second hinge shaft 5 and has a non-circular structure. The pawl tooth 41 portion has at least one pawl tooth 41. When there are two or more pawl teeth 41, a pawl tooth groove 42 is provided between two adjacent pawl teeth 41, thereby cooperating with the ratchet teeth 31 on the ratchet wheel 3 for greater stability.

[0045] The elastic element is a torsion spring 6, which is sleeved on the second hinge shaft 5 and located between the pawl 4 and the base frame 1.

[0046] In some specific implementations, such as Figures 1 to 3 As shown, to facilitate the user in disengaging the pawl 4 from the ratchet 3, a lever part 25 is provided on the base frame 1, and the lever part 25 is fixedly connected to the second hinge shaft 5. Since the pawl 4 and the second hinge shaft 5 rotate synchronously, the user can rotate the second hinge shaft 5 by turning the lever part 25 counterclockwise, thereby causing the pawl 4 to rotate and disengage from the ratchet 3.

[0047] In some specific implementations, such as Figures 1 to 3 As shown, the base frame 1 includes two supports 11 arranged side by side on the left and right, and a lower connecting frame 12 located between the rear ends of the two supports 11. Each support 11 is provided with a hinge groove 111 extending in the front-rear direction.

[0048] The guide frame 2 includes two guide rail frames 21 arranged side by side on the left and right, and an upper connecting frame 23 located between the upper parts of the two guide rail frames 21. Two guide rails 22 are respectively located on the two guide rail frames 21; the two guide rail frames 21 are hinged one-to-one in the two hinge slots 111. Specifically, when the tilt angle of the guide frame 2 is adjusted to 0 degrees, the two guide rail frames 21 fold into the two hinge slots 111, thereby making it more stable. At this time, the guide frame 2 and the base frame 1 are in a folded state. The guide rail frame 21 is specifically two fixedly connected clamping plates, and the guide rail 22 is disposed between the two clamping plates.

[0049] Each guide rail 21 is provided with two sets of angle adjusters between itself and its corresponding bracket 11, and the two sets of angle adjusters are located on the left and right sides of the guide rail 21, respectively.

[0050] To facilitate simultaneous adjustment of all angle adjusters, all ratchet wheels 3 and all pawls 4 are coaxially arranged. Specifically, all ratchet wheels 3 are coaxially arranged with the first hinge axis, and all pawls 4 are coaxially arranged with the second hinge axis 5.

[0051] In some specific implementations, such as Figures 1 to 3 As shown, to facilitate user operation of the climbing machine, a handrail frame 24 is provided on the upper connecting frame 23. The lower end of the handrail frame 24 is hinged to the upper connecting frame 23, and a locking element is detachably provided between the handrail frame 24 and the upper connecting frame 23. Specifically, the handrail frame 24 can be hinged to the upper connecting frame 23 via a hinge. The locking element can be a bolt 33, etc. Both the handrail frame 24 and the upper connecting frame 23 are provided with locking holes that cooperate with the bolt 33. The bolt 33 is inserted into the two locking holes, thereby locking the handrail frame 24 in the upward extended state. When the climbing machine is switched to folding mode, the bolt 33 is removed, thereby folding the handrail frame 24 together with the guide frame 2.

[0052] In some specific embodiments, the guide frame 2 and the base frame 1 are made of wood or metal.

[0053] In some specific implementations, such as Figures 1 to 3 As shown, to facilitate different users stepping on the pedal assembly 7, each pedal assembly 7 in this embodiment includes a pedal 71 and a sliding seat 72 located below the pedal 71. The sliding seat 72 is provided with a pulley, and the pedal 71 is hinged to the sliding seat 72 by a pin 711. The pedal 71 is provided with a plurality of first positioning holes 712 around the pin 711, and the sliding seat 72 is provided with a second positioning hole. The positioning pin 721 adjusts the tilt angle of the pedal 71 relative to the sliding seat 72 by engaging different first positioning holes 712 with the second positioning holes. When the angle between the guide frame 2 and the base frame 1 is 0 degrees, the user can adjust the tilt angle of the pedal 71 relative to the sliding seat 72 to 0 degrees, thereby facilitating the alternating sliding of the two sets of pedal assemblies 7.

[0054] Working principle explanation:

[0055] When the user adjusts the tilt angle of the guide frame 2 from small to large, the tilt angle of the guide frame 2 can be increased by rotating the guide frame 2 clockwise. When the user needs to rotate the guide frame 2 counterclockwise to reduce the tilt angle, the user first needs to disengage the pawl 4 from the ratchet 3, and then rotate the guide frame 2 counterclockwise to adjust its tilt angle. After the adjustment is completed, release the pawl 4, and the pawl 4 will re-engage with the ratchet 3 under the action of the elastic element, thereby locking the tilt angle of the guide frame 2 relative to the base frame 1.

[0056] This utility model is not limited to the above-mentioned optional embodiments. Under the premise of non-contradiction, the various solutions can be combined arbitrarily. Anyone can derive other forms of products under the guidance of this utility model. However, regardless of any changes made in their shape or structure, all technical solutions that fall within the scope of the claims of this utility model are within the protection scope of this utility model.
