Description

Technical Field

[0001] This utility model belongs to the field of fitness equipment technology, specifically relating to a stepper. Background Technology

[0002] People are often busy with work, especially office workers who spend long hours hunched over desks and those in non-manual labor professions, making them prone to common occupational diseases such as lower back pain and joint stiffness. Therefore, people often use stepper machines for exercise, which can effectively improve these problems. Stepper machines are becoming increasingly popular due to their small footprint, ease of storage, and ability to be used anytime. Existing stepper machines mainly consist of a frame and two pedals, both hinged to the frame, with springs or elastic ropes connecting the pedals to the frame, allowing the user to move the two pedals up and down alternately. Current stepper technology only trains the stepping motion, offering limited functionality, thus requiring improvement. Utility Model Content

[0003] This utility model provides a stepper machine, which aims to solve the problem that existing stepper machines can only train stepping movements and have limited functionality.

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

[0005] A stepper machine, comprising:

[0006] The base frame includes a central support and two arc-shaped side frames. The two arc-shaped side frames are located on the front and rear sides of the central support, respectively. Roller assemblies for supporting the central support on the ground are provided on both the left and right sides of the central support. The arc-shaped side frames are arranged with their openings facing upwards.

[0007] Two sets of pedal assemblies are located on the left and right sides of the base frame, respectively. Each set of pedal assemblies is rotatably connected to two arc-shaped side frames, and each set of pedal assemblies is hinged to the intermediate support via a connecting rod; and,

[0008] An elastic torsion member is mounted on the base frame. The middle part of the elastic torsion member is connected to the intermediate support, and the front and rear ends of the elastic torsion member are respectively connected to two arc-shaped side frames.

[0009] A further solution: Each set of pedal assemblies is provided with at least one elastic resistance element between it and the intermediate support.

[0010] Based on the above technical solution: by setting elastic resistance components between each set of pedal components and the middle support, when one side of the pedal component rises, the corresponding elastic resistance component is stretched to generate elastic resistance, thereby helping users achieve better fitness results. When the two sets of pedal components move up and down alternately, they will drive the arc-shaped side frame to swing back and forth, causing the elastic resistance components on both sides to be stretched back and forth, which can help users master balance. When there are multiple elastic resistance components, users can assemble different numbers of elastic resistance components according to their own needs, thereby making it suitable for a wider range of people.

[0011] A further embodiment: Each set of pedal assemblies is provided with a first pivot between it and the two arc-shaped side frames. The front and rear ends of the first pivot are respectively rotatably connected to the two arc-shaped side frames. The pedal assembly is located on the upper side of the first pivot and is fixedly connected to the first pivot.

[0012] Based on the above technical solution: the above settings enable the two side frames to swing left and right in better synchronization.

[0013] A further embodiment: each of the first rotating shafts is provided with a first hooking part on its lower side, and the middle bracket is provided with a second hooking part on both the left and right sides; the two ends of each elastic resistance member are respectively hooked onto the corresponding first hooking part and second hooking part.

[0014] Based on the above technical solution, the above settings facilitate quick assembly and disassembly.

[0015] A further option: all the elastic resistance elements between each set of pedal assemblies and the intermediate support are arranged side by side.

[0016] A further solution: the elastic resistance element is an elastic rope, and both the upper and lower ends of the elastic rope can be detachably connected to the first hook part and the second hook part.

[0017] Based on the above technical solution: using an elastic rope reduces costs and allows users to quickly assemble according to their needs.

[0018] A further solution: Both the first and second attachment parts are hooks.

[0019] A further option: the elastic torsion member is made of beef tendon.

[0020] A further embodiment: The upper part of the intermediate support is provided with a first support, the lower side of the pedal assembly is provided with a second support, one end of each link is hinged to the first support, and the other end of each link is hinged to the corresponding second support.

[0021] A further embodiment: the roller assembly includes a roller and a roller damping element for adjusting the rolling resistance of the roller.

[0022] Based on the above technical solution, by adjusting the rolling resistance of the rollers, users can be further assisted in achieving better fitness results.

[0023] The beneficial effects of this utility model are as follows:

[0024] This invention features a base frame comprising a central support and two arc-shaped side frames. During use, the roller assembly at the lower end of the central support and the lower ends of the arc-shaped side frames are both supported on the ground. An elastic torsion member is connected to the central support at its center, and its front and rear ends are connected to the two arc-shaped side frames respectively. This allows the user to step on the two sets of pedal assemblies with both feet, applying force alternately from left to right, causing the two sets of pedal assemblies to move up and down alternately. When the left pedal assembly descends, it causes the arc-shaped side frame to swing to the left. At this time, the elastic torsion member generates torsional resistance, which drives the arc-shaped side frame to swing back to the right. The same applies to the descent of the right pedal assembly. Thus, during stepping exercises, the user's body sways back and forth, helping to train balance and stability. This makes the stepper of this invention more functional and suitable for widespread application.

[0025] By setting the roller assembly to roll in contact with the ground, it not only helps protect the ground, but also helps train the user's balance ability by rolling the roller assembly synchronously left and right when the curved side frame swings left and right. Attached Figure Description

Detailed Implementation

[0033] 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.

[0034] like Figures 1 to 4 As shown, this embodiment provides a stepper, including:

[0035] The base frame 1 includes a central support 11 and two arc-shaped side frames 12, which are located on the front and rear sides of the central support 11, respectively. Roller assemblies 113 for supporting the central support 11 on the ground are provided on both the left and right sides of the central support 11. The arc-shaped side frames 12 have their openings facing upwards. Each arc-shaped side frame 12 specifically includes an arc-shaped rod 121 with its opening facing upwards and a crossbar 122 connecting the two ends of the arc-shaped rod 121. The bottoms of the two arc-shaped rods 121 are connected by a connecting rod for better stability.

[0036] Two sets of pedal assemblies 4 are located on the left and right sides of the base frame 1, respectively. Each set of pedal assemblies 4 is rotatably connected to two arc-shaped side frames 12, and each set of pedal assemblies 4 is hinged to the intermediate support 11 via a connecting rod 14; and,

[0037] An elastic torsion member 2 is mounted on the base frame 1. The middle part of the elastic torsion member 2 is connected to the intermediate support 11, and the front and rear ends of the elastic torsion member 2 are respectively connected to two arc-shaped side frames 12.

[0038] In some specific implementations, such as Figures 1 to 4 As shown, the elastic torsion member 2 is a tendon, which can be shaped as a cuboid or a polygon with a longitudinal section. For ease of fixing, a cuboid shape is preferred. The upper end of the intermediate support 11 is provided with a second fixing frame 114, and the upper end of each arc-shaped side frame 12 is provided with a first fixing frame 124. The front and rear ends of the cuboid tendon are fixed to the two first fixing frames 124 respectively, and the middle part of the cuboid tendon is fixed to the second fixing frame 114.

[0039] In some specific embodiments, at least one elastic resistance element is provided between each set of pedal assemblies 4 and the intermediate support 11. Specifically, when a user exercises using the stepper, when one of the pedal assemblies 4 is pushed up, the corresponding elastic resistance element is stretched to generate elastic resistance, thereby assisting the user to achieve better fitness results. Preferably, there are multiple elastic resistance elements, and both ends of the elastic resistance elements can be detachably connected to the pedal assembly 4 and the intermediate support 11, so that the user can easily change the number according to needs.

[0040] In some specific implementations, such as Figures 1 to 4 As shown, each set of pedal assemblies 4 is provided with a first pivot 13 between it and the two arc-shaped side frames 12. The front and rear ends of the first pivot 13 are respectively rotatably connected to the two arc-shaped side frames 12. The pedal assembly 4 is located on the upper side of the first pivot 13 and is fixedly connected to the first pivot 13. Specifically, each arc-shaped side frame 12 has two left and right hinge brackets 123 on its crossbar 122, and the front and rear ends of the first pivot 13 are respectively rotatably connected to the two corresponding hinge brackets 123.

[0041] Each of the first rotating shafts 13 has a first hooking part 131 on its lower side, and the middle bracket 11 has a second hooking part 112 on its left and right sides; the two ends of each elastic resistance member are respectively hooked onto the corresponding first hooking part 131 and second hooking part 112.

[0042] Specifically, the elastic resistance element can be an elastic rope 3 or a spring, etc., and both ends of the elastic rope 3 can be detachably connected to the first hook part 131 and the second hook part 112. When there are multiple elastic resistance elements, all the elastic resistance elements between each group of pedal assembly 4 and the intermediate support 11 are arranged side by side. The first hook part 131 on each first rotating shaft 13 is arranged side by side, and the left and right sides of the intermediate support 11 are provided with hooks extending forward and backward, and the second hook parts 112 corresponding to the hooks are arranged side by side.

[0043] In order to facilitate the user's disassembly and assembly of the elastic rope 3, both the first hook part 131 and the second hook part 112 are hooks.

[0044] In some specific implementations, such as Figures 1 to 4 As shown, the upper part of the intermediate support 11 is provided with a first support 111, and the lower side of the pedal assembly 4 is provided with a second support 41. One end of each connecting rod 14 is hinged to the first support 111, and the other end of each connecting rod 14 is hinged to its corresponding second support 41. The second support 41 is fixedly connected to the first rotating shaft 13.

[0045] In some specific embodiments, in order to enable the stepper to achieve better fitness results, the roller assembly 113 includes rollers and roller damping components for adjusting the rolling resistance of the rollers. Specifically, the roller damping components can be brake pad structures in the prior art.

[0046] Working principle explanation:

[0047] The user places both feet on the two sets of pedal assemblies 4 respectively, and applies force alternately to the left and right to make the two sets of pedal assemblies 4 move up and down alternately. When the left pedal assembly 4 descends, it will cause the arc-shaped side frame 12 to swing to the left. At this time, the elastic torsion member 2 generates torsional resistance, which drives the arc-shaped side frame 12 to swing to the right to reset. At the same time, the arc-shaped side frame 12 will drive the middle support 11 to move to the left a certain distance. Specifically, the middle support 11 rolls to the left through the roller assembly 113.

[0048] The same principle applies to the descent of the right pedal assembly 4. This causes the body to sway back and forth during stepping exercises, which helps train the user's balance.

[0049] 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, no matter what changes are 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.
