Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, specifically relating to a stair climber equipped with a tension spring. Background Technology

[0002] Currently, a stair climber has appeared on the market that can simulate mountain climbing or stair climbing movements. It mainly consists of a front frame and a rear frame that open at a certain angle. The front frame has a handrail, and the rear frame has two sets of pedal assemblies and a traction rope pulley. A traction rope, passing around the traction rope pulley, connects the two sets of pedal assemblies. During use, the user places their feet on the two sets of pedal assemblies, causing them to slide back and forth alternately at a certain angle, simulating the training movements of mountain climbing. However, this type of stair climber in the current technology cannot provide sufficient resistance for the back-and-forth sliding of the pedal assemblies, thus failing to achieve optimal fitness results. Utility Model Content

[0003] This invention provides a stair climber equipped with a tension spring, which aims to solve the problem that existing stair climbers cannot provide sufficient resistance for the forward and backward sliding of the pedal assembly, thus failing to achieve better fitness results.

[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 a tension spring, characterized in that it comprises:

[0006] A climbing frame support, comprising two guide sections, left and right, angled upwards from back to front, and a traction sheave; and...

[0007] The left and right sets of pedal assemblies are slidably mounted on the two guide parts, and a traction rope is provided between the two sets of pedal assemblies and passing around the traction rope wheel; a tension spring is provided between each set of pedal assemblies and the mountaineering machine frame.

[0008] A further embodiment: the upper end of each tension spring is connected to the mountaineering machine bracket, and the lower end of each tension spring is provided with a connecting rope between it and its corresponding pedal assembly.

[0009] A further embodiment: Each set of pedal assemblies is provided with a rope wheel assembly between itself and the mountaineering machine support for the connecting rope corresponding to that set of pedal assemblies to pass around;

[0010] One end of each connecting rope is connected to its corresponding tension spring, and the other end of each connecting rope is connected to its corresponding pedal assembly after passing over its corresponding rope winding wheel assembly.

[0011] Based on the above technical solution: the tension spring is connected to the pedal assembly via a connecting rope, which facilitates the connection. The connecting rope is arranged to bypass the rope wheel, so that when the two sets of pedal assemblies slide up and down alternately, the connecting rope is prevented from getting knotted or tangled.

[0012] A further embodiment: each of the rope wheel assemblies includes a second rope wheel assembly mounted on the mountaineering machine bracket; the second rope wheel assembly includes at least one second rope wheel.

[0013] A further solution: When the second winding wheel assembly includes two second winding wheels, the arrangement direction of the two second winding wheels of the second winding wheel assembly is parallel to the guide portion, and the connecting rope corresponding to the second winding wheel assembly passes through the middle of the two second winding wheels.

[0014] Based on the above technical solution: by setting the two second rope wheels in each group of second rope wheel assemblies to be arranged along the extension direction of the guide portion, and the connecting rope corresponding to the group of second rope wheel assemblies passing through the middle of the two second rope wheels, it is possible to avoid the phenomenon of the connecting rope detaching from the second rope wheel when the pedal assembly slides along the guide portion.

[0015] A further embodiment: The climbing frame is provided with a wheel frame parallel to the guide portion, and the wheel frame is located between the two guide portions;

[0016] The two sets of the second rope-winding wheel assemblies are located on the left and right sides of the wheel frame, respectively.

[0017] Based on the above technical solution: the above setting facilitates the installation of the second rope winding wheel, and also facilitates the two connecting ropes to pass around their corresponding second rope winding wheels, avoiding problems such as tangling and knotting of the two connecting ropes.

[0018] A further embodiment: Each group of the winding wheel assembly also includes a first winding wheel disposed on the corresponding pedal assembly, and the connecting rope corresponding to the pedal assembly passes around the first winding wheel on the pedal assembly;

[0019] The first rope wheel on the left pedal assembly is located on the right side of the pedal assembly, and the first rope wheel on the right pedal assembly is located on the left side of the pedal assembly.

[0020] Based on the above technical solution: by setting a first rope winding wheel assembly on the pedal assembly, the connecting rope can be connected to the pedal assembly after passing around the corresponding first rope winding wheel assembly, which can further avoid the problem of the connecting rope getting tangled.

[0021] A further embodiment: each of the connecting ropes is detachably connected to its corresponding pedal assembly and / or tension spring.

[0022] Based on the above technical solution: the above setting facilitates user operation in assembling and disassembling the connecting rope, thereby allowing the connecting rope to pass around the second winding wheel at different positions, thus adjusting the elastic resistance of the tension spring.

[0023] A further embodiment: Each set of pedal assemblies is provided with a rope connection part, and the two ends of the traction rope are respectively connected to two of the rope connection parts, and each connection rope is detachably connected to the rope connection part on its corresponding side.

[0024] Based on the above technical solution: for each pedal assembly, the traction rope and connecting rope connected to it share a rope connection part, thereby optimizing the structure and making it easier for users to assemble.

[0025] A further option: a climbing machine equipped with a tension spring, further comprising:

[0026] The two adjusters, one on the left and one on the right, are used to adjust the elastic resistance of the two tension springs respectively; the two adjusters are respectively located on the left and right sides of the climbing frame; or, the two adjusters are respectively located on the corresponding pedal assemblies.

[0027] Based on the above technical solution: by setting an adjuster to adjust the elastic resistance of the tension spring, different users can adjust it according to their own needs, so as to better meet the fitness needs of different users.

[0028] A further option: the two adjusters are respectively installed on the left and right sides of the climbing frame;

[0029] The adjuster includes an adjusting rod and a locking member. The lower end of the adjusting rod is connected to the upper end of the tension spring, and the adjusting rod is slidably disposed on the climbing frame bracket along the extension direction of the guide portion. The locking member is used to lock the position of the adjusting rod relative to the climbing frame bracket. The elastic resistance of the tension spring can be adjusted by driving the adjusting rod to move away from or toward the tension spring.

[0030] Based on the above technical solution: by setting the adjuster including an adjusting rod, the spring can be stretched to increase its elastic resistance or restored to decrease its elastic resistance by moving the adjusting rod up and down relative to the spring, which is convenient for user operation. A locking element is set to lock the position of the adjusting rod relative to the climbing frame bracket, thereby adjusting and locking the elastic resistance of the spring.

[0031] A further embodiment: the locking element is a knob rotatably mounted on the mountaineering machine bracket, the adjusting rod passes through the knob, and each adjusting rod is threadedly connected to its corresponding knob.

[0032] Based on the above technical solution: by setting a knob, users can easily adjust the elastic resistance of the tension spring by rotating the knob.

[0033] The beneficial effects of this utility model are as follows:

[0034] In this invention, a tension spring is installed between each set of pedal assemblies and the stair climber frame. When the user drives the two sets of pedal assemblies to slide back and forth alternately along two guide sections, the tension spring provides elastic resistance to the pedal assemblies. This forces the user to overcome the elastic resistance, thus enabling better fitness results. Furthermore, using tension springs to provide elastic resistance has the advantages of easy installation and low cost. The elastic resistance of the tension spring increases with the extension length, providing better functional training for muscles when the user uses the stair climber to simulate climbing movements. Simultaneously, the elastic resistance of the tension spring also acts as a buffer, protecting the user's knees from injury. Attached Figure Description

[0043] 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.

[0044] like Figures 1 to 5 As shown, this embodiment provides a climbing machine equipped with a tension spring, including:

[0045] A climbing frame bracket 1, wherein the climbing frame bracket 1 is provided with two guide sections 111, one on the left and one on the right, which are inclined upwards from back to front; the climbing frame bracket 1 is also provided with a traction rope pulley 113; and...

[0046] The left and right pedal assemblies 2 are slidably mounted on the two guide parts 111 respectively, and a traction rope 114 is provided between the two pedal assemblies 2 and passing around the traction rope wheel 113; a tension spring 32 is provided between each pedal assembly 2 and the mountaineering machine bracket 1.

[0047] In some specific implementations, such as Figure 1 As shown, the upper end of each tension spring 32 is connected to the mountaineering machine bracket 1, and the lower end of each tension spring 32 is provided with a connecting rope 31 between it and the corresponding pedal assembly 2. Each set of pedal assemblies 2 and the mountaineering machine bracket 1 is provided with a rope wheel assembly for the connecting rope 31 corresponding to that set of pedal assemblies 2 to pass around.

[0048] One end of each connecting rope 31 is connected to its corresponding tension spring 32, and the other end of each connecting rope 31 is connected to its corresponding pedal assembly after passing over its corresponding rope winding wheel assembly.

[0049] Specifically, the traction rope 114 and the connecting rope 31 can be steel wire ropes, etc.

[0050] In some specific implementations, such as Figures 1 to 5As shown, each group of rope wheel assemblies includes a second rope wheel assembly mounted on the mountaineering machine bracket 1. The second rope wheel assembly includes at least one second rope wheel 115. When the second rope wheel assembly includes two second rope wheels 115, the arrangement direction of the two second rope wheels 115 is parallel to the guide portion 111. The connecting rope 31 corresponding to this group of second rope wheel assemblies passes through the middle of the two second rope wheels 115, preventing the connecting rope 31 from detaching from its corresponding second rope wheel 115 when the pedal assembly 2 slides along the guide portion 111. When the second rope wheel assembly includes three or more second rope wheels 115, the connecting rope 31 corresponding to this group of second rope wheel assemblies passes through the middle of any two adjacent second rope wheels 115.

[0051] The mountaineering machine bracket 1 is provided with a wheel frame 112 parallel to the guide portion 111 and the wheel frame 112 is located between the two guide portions 111; specifically, the wheel frame 112 is located on the lower side of the two tension springs 32, and the bottom of the wheel frame 112 is located between the two guide portions 111 and extends upward from bottom to top, parallel to the guide portions 111.

[0052] The two sets of the second rope-winding wheel assemblies are located on the left and right sides of the wheel frame 112, respectively.

[0053] In some specific implementations, such as Figure 1 As shown, each set of the winding wheel assembly also includes a first winding wheel 222 disposed on the corresponding pedal assembly 2, and the connecting rope 31 corresponding to the pedal assembly 2 passes around the first winding wheel 222 on the pedal assembly 2. The first winding wheel 222 on the left pedal assembly 2 is located on the right side of the pedal assembly 2, and the first winding wheel 222 on the right pedal assembly 2 is located on the left side of the pedal assembly 2.

[0054] In some specific implementations, such as Figure 1 As shown, each set of pedal assemblies 2 is provided with a rope connecting part 221. The two ends of the traction rope 114 are respectively connected to two rope connecting parts 221, and each connecting rope 31 is detachably connected to the rope connecting part 221 on its corresponding side. Specifically, the rope connecting part 221 is a pin, and both ends of the traction rope 114 are provided with a first loop, which is sleeved on the corresponding pin; the end of the connecting rope 31 used to connect to the rope connecting part 221 is provided with a second loop, which is sleeved on the pin.

[0055] In some specific implementations, such as Figure 1As shown, there are two traction sheaves 113, both located between the two guide portions 111, and two adjusting rods 116 are located between the two traction sheaves 113. The guide portion 111 is specifically a guide frame.

[0056] In some specific implementations, such as Figure 1 , Figure 4 and Figure 5 As shown, the climbing machine also includes two left and right adjusters, which are used to adjust the elastic resistance of the two tension springs 32 respectively; the two adjusters are respectively disposed on the left and right sides of the climbing machine bracket 1; or, the two adjusters are respectively disposed on the corresponding pedal assembly 2.

[0057] In some specific implementations, such as Figure 1 , Figure 4 and Figure 5 As shown, the two adjusters are preferably respectively disposed on the left and right sides of the mountaineering machine bracket 1; specifically, a crossbar is provided between the upper ends of the two guide parts, and both adjusters are disposed on the crossbar.

[0058] The adjuster includes an adjusting rod 116 and a locking member. The lower end of the adjusting rod 116 is connected to the upper end of the tension spring 32, and the adjusting rod 116 is slidably disposed on the crossbar along the extending direction of the tension spring 32. The locking member is used to lock the position of the adjusting rod 116 relative to the crossbar. The elastic resistance of the tension spring 32 can be adjusted by driving the adjusting rod 116 away from or towards the tension spring 32. Specifically, when the adjusting rod 116 is moved away from the tension spring 32, the tension spring 32 will be stretched, increasing its elastic resistance; when the adjusting rod 116 is moved towards the tension spring 32, the tension spring 32 will return to its original position, thereby reducing its elastic resistance.

[0059] The locking element is preferably a knob 117 rotatably mounted on the mountaineering machine bracket 1. An adjusting rod 116 passes through the knob 117, and each adjusting rod 116 is threadedly connected to its corresponding knob 117. Specifically, rotating the knob 117 will cause the adjusting rod 116 to move upwards away from the tension spring 32 or downwards towards the tension spring 32.

[0060] When the regulator is installed on the corresponding pedal assembly, one end of the regulator is connected to the connecting rope and the other end is connected to the pedal assembly.

[0061] In some specific implementations, such as Figures 1 to 4As shown, the mountaineering machine support 1 includes a front support 12, a rear support 11, and a handrail 13 located on the front support 12. There are two handrails 13, left and right, and both handrails 13 are rotatably and / or telescopically connected to the front support 12. Preferably, the handrails 13 are rotatably and telescopically connected to the front support 12, and each handrail 13 is provided with an adjusting bolt 5 between it and the front support 12. The handrails 13 and the front support 12 are provided with limiting holes that cooperate with the adjusting bolts 5. The adjusting bolts 5 adjust the length of the handrail 13 extending relative to the front support 12 or the angle of relative rotation by cooperating with different limiting holes. Both guide portions 111 are located on the rear support 11. The upper ends of the front support 12 and the rear support 11 are hinged together by a hinge shaft. The front support 12 and the rear support 11 have an unfolded state where they are spread apart and a folded state where they are folded together. A locking assembly 14 is provided between the front support 12 and the rear support 11 to lock the front support 12 and the rear support 11 in the unfolded state. The locking assembly 14 includes two bolts on the left and right sides. The front support 12 and the rear support 11 each have bolt holes that mate with the two bolts. Each bolt locks the front support 12 and the rear support 11 in the unfolded state by inserting it into the bolt hole on the corresponding front support 12 and the rear support 11.

[0062] In some specific implementations, such as Figures 1 to 4 As shown, the pedal assembly 2 includes a sliding seat 22 slidably connected to the guide portion 111 and a pedal 21 hinged to the sliding seat 22. An angle adjustment assembly for adjusting and locking the tilt angle of the pedal 21 relative to the sliding seat 22 is provided between the pedal 21 and the sliding seat 22. Specifically, the rope connection portion 221 and the first rope winding wheel 222 are both disposed on the corresponding sliding seat 22. The pedal 21 is hinged to the sliding seat 22 via a pivot. The angle adjustment assembly includes a plurality of first positioning holes 41 disposed on the pedal 21, a second positioning hole disposed on the sliding seat 22, and a positioning pin 42. The plurality of first positioning holes 41 are arranged around the pivot. The positioning pin 42 adjusts and locks the tilt angle of the pedal 21 relative to the sliding seat 22 by cooperating with different first positioning holes 41 and second positioning holes.

[0063] Working principle explanation:

[0064] When adjusting the elastic resistance of the tension spring 32, the knob 117 can be rotated. The knob 117 is threadedly connected to the adjusting rod 116. When the adjusting rod 116 is driven to move upward away from the tension spring, the tension spring is stretched, increasing the elastic resistance it generates. When the adjusting rod 116 is driven to move downward toward the tension spring, the tension spring returns to its original position, thereby reducing the elastic resistance generated by the tension spring on its corresponding pedal assembly 2.

[0065] 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.
