Description

Technical Field

[0001] This utility model relates to a sports device, and more particularly to a dual-function stepper. Background Technology

[0002] With increasing health awareness, the demand for fitness equipment is growing. Steppers, as a common indoor fitness device, are popular because they simulate climbing stairs or walking, helping users exercise lower limb muscles and improve cardiovascular function. However, most existing steppers only support a single up-and-down stepping motion, offering limited functionality and failing to meet users' needs for a diverse exercise experience. Furthermore, a single exercise mode can easily lead to boredom during prolonged use and cannot comprehensively train core muscles and improve body coordination.

[0003] In recent years, some steppers have appeared on the market attempting to introduce diverse exercise modes, such as manually adjusting the pedal angle or replacing parts to achieve different exercise methods. However, these designs have obvious limitations: firstly, they are complex to operate, requiring users to manually adjust or replace parts, which is not only time-consuming and laborious but may also lead to equipment damage or safety hazards due to improper operation; secondly, their complex structure increases the manufacturing cost and maintenance difficulty of the equipment. (Refer to utility model patent "201420359929.9 - A Novel Stepper")

[0004] To address the aforementioned issues, this invention proposes a stepper with a structure for switching between two movement modes: "up and down stepping" and "left and right twisting stepping," enabling quick and convenient switching between the two modes. Summary of the Invention

[0005] This utility model discloses a dual-function stepper, which solves the problems of complex operation and complex structure of existing stepper modes.

[0006] A dual-function stepper includes a base with a rotating shaft mounted on it. A foot pedal connecting mechanism for connecting a pair of foot pedal components and a linkage mechanism acting between the pair of foot pedal components are pivotally connected to the rotating shaft. When the linkage mechanism and the base are relatively fixed, the foot pedal components move in a left-right twisting stepping mode; when the foot pedal connecting mechanism and the base are relatively fixed, the foot pedal components move in an up-down stepping mode.

[0007] The stepper also includes a button locking mechanism, which includes a fixing component connected to the end of the rotating shaft and fixed in position relative to the base; and

[0008] A limiting pin connecting piece is provided on the fixed component. The limiting pin connecting piece is movably connected to the fixed component to form a lever structure. Limiting pins are respectively provided at both ends of the limiting pin connecting piece. One end of the limiting pin is movably connected to the end of the limiting pin connecting piece.

[0009] The fixed component is provided with two limit pin movable holes corresponding to the limit pins respectively, for the limit pins to pass through; the linkage mechanism is provided with a first limit hole, and the foot pedal connecting mechanism is provided with a second limit hole, and the first limit hole and the second limit hole each correspond to one limit pin;

[0010] In the left and right twisting step mode, one limiting pin partially passes through the limiting pin movable hole and falls into the first limiting hole, while the other limiting pin leaves the second limiting hole.

[0011] In the up-and-down stepping mode, one limiting pin partially passes through the limiting pin movable hole and falls into the second limiting hole, while the other limiting pin leaves the first limiting hole.

[0012] This invention includes a button locking mechanism for switching between the "up and down stepping" and "left and right twisting stepping" modes of a stepper. The fixed component, after being connected to the rotating shaft, forms a single unit with the base. A limiting pin connecting piece is movably connected to the fixed component, forming a lever structure, and has limiting pins at both ends. One limiting pin restricts the relative rotation between the linkage mechanism and the base, while the other restricts the relative rotation between the foot pedal connecting mechanism and the base. Thus, pressing the limiting pin connecting piece allows for convenient switching between the left and right twisting stepping mode and the up and down stepping mode.

[0013] Several alternative methods are provided below, but they are not intended as additional limitations on the overall solution above. They are merely further additions or optimizations. Provided there are no technical or logical contradictions, each alternative method can be combined individually with respect to the overall solution above, or multiple alternative methods can be combined with each other.

[0014] Optionally, the fixing component includes a fixing seat and a connecting seat. The fixing seat is connected to the rotating shaft, and the connecting seat is located on the fixing seat for connecting with the limiting pin connecting piece to form the lever structure.

[0015] Optionally, the connecting seat has a set of opposing columns and a rotating pin connecting the two columns, and the middle part of the limiting pin connecting piece is rotatably connected to the rotating pin.

[0016] Optionally, one end of the limiting pin is rotatably connected to the end of the limiting pin connecting piece.

[0017] Optionally, the foot pedal assembly includes a pedal, a pedal bracket for securing the pedal, and a hydraulic rod;

[0018] The foot pedal connection mechanism includes a rocker arm, which is arranged parallel to the base. One end of the rocker arm is pivotally connected to the rotating shaft, and the other end is connected to a vertical rod. The vertical rod is provided with a parallel foot pedal connection shaft and a hydraulic rod connection shaft.

[0019] One end of the pedal frame is rotatably connected to the foot pedal connecting shaft, forming a pivot end and a swing end opposite to each other;

[0020] One end of the hydraulic rod is rotatably connected to the hydraulic rod connecting shaft, and the other end is rotatably connected to the swing end.

[0021] Optionally, the linkage mechanism includes a pair of pull rods and a connecting plate. The connecting plate is rotatably connected to the rotating shaft, and the pair of pull rods are respectively rotatably connected to opposite ends of the connecting plate. The pull rods are rotatably connected to the pivot end of the pedal frame.

[0022] Optionally, the second limiting hole is provided on the rocker arm, and the first limiting hole is provided on the connecting piece.

[0023] Optionally, a first buffer component is provided at the first limiting hole, and the first buffer component acts on the side wall of the limiting pin.

[0024] Optionally, a second buffer component is provided at the second limiting hole, and the second buffer component acts on the side wall of the limiting pin.

[0025] Optionally, the mounting bracket extends partially into the base and is fixed to the base by fasteners.

[0026] The beneficial effects of this application are as follows:

[0027] After the fixed component is connected to the rotating shaft, it forms a whole with the base. The limiting pin connecting piece is movably connected to the fixed component to form a lever structure, and its two ends have movably connected limiting pins. One limiting pin is used to limit the relative rotation between the linkage mechanism and the base, and the other limiting pin is used to limit the relative rotation between the foot pedal connecting mechanism and the base. Thus, by pressing the limiting pin connecting piece, the left and right twisting step mode and the up and down step mode can be easily switched. Attached Figure Description

[0041] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0042] It should be noted that when a component is said to be "connected" to another component, it can be directly connected to the other component or it can be connected to a component in between. When a component is said to be "set on" another component, it can be directly set on the other component or it may be set to a component in between.

[0043] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of the application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0044] refer to Figures 1 to 7 In one embodiment of this utility model, a dual-function stepper is disclosed, including a base 1, a foot pedal connecting mechanism 3, a pair of foot pedal components 2 rotatably connected to the foot pedal connecting mechanism 3, and a linkage mechanism 4 acting between the pair of foot pedal components 2.

[0045] Among them, a rotating shaft 11 is provided at the upper end of the base 1, one end of which is fixed to the base 1. The foot pedal connecting mechanism 3 and the linkage mechanism 4 each have their own rotating parts for pivotally connecting with the rotating shaft 11.

[0046] It should be explained that the "rotating component" mentioned above refers to the part of the foot pedal connecting mechanism 3 and the linkage mechanism 4 that is pivotally connected to the rotating shaft 11. The two "rotating components" have different structures. For the sake of simplicity in the embodiment, they are both described as "rotating components".

[0047] Since the "left and right twisting stepping" and "up and down stepping" movement modes are existing technologies, this application only provides a general description of how the stepper performs the "left and right twisting stepping" or "up and down stepping" movement modes, without going into detail.

[0048] refer to Figure 6 and Figure 7 , combined Figure 1 In the "left and right twisting step" movement mode, the "rotating component" on the linkage mechanism 4 is fixed relative to the base 1, and the foot pedal assembly 2 acts on the linkage mechanism 4 to drive the foot pedal connecting mechanism 3 to rotate around the rotating axis 11.

[0049] refer to Figure 4 and Figure 5 , combined Figure 1 In the "stepping up and down" movement mode, the "rotating component" on the foot pedal connecting mechanism 3 is fixed relative to the base 1, and the foot pedal assembly 2 drives the linkage mechanism 4 to rotate around the rotating axis 11.

[0050] The stepper in this embodiment also includes a button locking mechanism 5, which includes a fixing component 51. The fixing component 51 is connected to the rotating shaft 11 and forms a fixing structure with the base 1 to maintain a consistent relative position, for fixing the button locking mechanism 5 to the base 1.

[0051] Furthermore, a limiting pin connecting piece 52 is movably connected to the fixed component 51. The limiting pin connecting piece 52 forms a lever structure on the fixed component 51 with both ends rotating around the middle. A limiting pin 53 is provided at each end of the limiting pin connecting piece 52.

[0052] One end of the limiting pin 53 is movably connected to the end of the limiting pin connecting piece 52. When one end of the limiting pin connecting piece 52 is pressed, one limiting pin 53 moves downward and the other limiting pin 53 moves upward. The limiting pins 53 are used to fix the aforementioned "rotating component" relative to the base 1.

[0053] Further reference Figure 1 The fixed component 51 has two limit pin movable holes 54 for the limit pins 53 to pass through. Correspondingly, the linkage mechanism 4 is provided with a first limit hole 421. When the limit pins 53 simultaneously fall into the limit pin movable holes 54 and the first limit hole 421, the linkage mechanism 4 and the base 1 are fixed together. The foot pedal connecting mechanism 3 is provided with a second limit hole 311. When the limit pins 53 simultaneously fall into the limit pin movable holes 54 and the second limit hole 311, the foot pedal connecting mechanism 3 and the base 1 are fixed together.

[0054] For details, please refer to Figure 1 The fixing component 51 in the button locking mechanism 5 includes a fixing seat 511 and a connecting seat 512. The fixing seat 511 is connected to the rotating shaft 11 and serves as a fixing component between the connecting seat 512 and the base 1. The connecting seat 512 has a set of opposing columns 32, and a rotating pin 514 is provided between the two columns 32. The rotating pin 514 is rotatably connected to the middle of the limiting pin connecting piece 52 to form the lever structure described above.

[0055] refer to Figures 1 to 3 The foot pedal connection mechanism 3 includes a rocker arm 31, which is set parallel to the base 1. One end of the rocker arm 31 is pivotally connected to the rotating shaft 11, and the other end is connected to a vertical rod 32. The vertical rod 32 is provided with a parallel foot pedal connection shaft 33 and a hydraulic rod connection shaft 34.

[0056] The foot pedal assembly 2 includes a pedal 21, a pedal bracket 22 for fixing the pedal 21, and a hydraulic rod 23;

[0057] One end of the pedal frame 22 is rotatably connected to the foot pedal connecting shaft 33, forming a pivot end 221 and a swing end 222;

[0058] One end of the hydraulic rod 23 is rotatably connected to the hydraulic rod connecting shaft 34, and the other end is rotatably connected to the swing end 222.

[0059] Furthermore, the linkage mechanism 4 includes a pair of pull rods 41 and a connecting plate 42. The connecting plate 42 is rotatably connected to the rotating shaft 11, and the pair of pull rods 41 are respectively rotatably connected to the opposite ends of the connecting plate 42. The pull rods 41 are rotatably connected to the pivot end 221 of the pedal frame 22.

[0060] In actual use, the user steps on the pedal 21 to drive the pedal frame 22 to rotate around the pivot end 221, and the swing end 222 presses the hydraulic rod 23.

[0061] refer to Figure 4 and Figure 5 During the "stepping up and down" movement, the foot pedal connecting mechanism 3 is relatively fixed to the base 1 by the button locking mechanism 5, and the lever 41 is driven by the pivot end 221 to drive the foot pedal assembly 2 to swing the connecting plate 42.

[0062] refer to Figure 6 and Figure 7 During the "left and right twisting stepping" movement, the linkage plate 42 is relatively fixed to the base 1 by the button locking mechanism 5. After stepping on the pedal 21, the pivot end 221 and the connection of the pull rod 41 form a moving tendency away. At this time, the pull rod 41 plays a pulling role, pulling the foot pedal connecting mechanism 3 to the stepping side, thereby forming a left and right twisting state.

[0063] Furthermore, the second limiting hole 311 is provided on the rocker arm 31, and the first limiting hole 421 is provided on the connecting piece 42.

[0064] To reduce the shaking of the stepper during exercise, a first buffer component 43 is provided at the first limiting hole 421. The first buffer component 43 acts on the side wall of the limiting pin 53 to alleviate the collision between the limiting pin 53 and the connecting piece 42 during the "left and right twisting stepping" movement.

[0065] A second buffer component 35 is provided at the second limiting hole 311. The second buffer component 35 acts on the side wall of the limiting pin 53 to alleviate the collision between the limiting pin 53 and the rocker arm 31 during the "stepping up and down" movement.

[0066] refer to Figure 3 In order to strengthen the connection between the button locking mechanism 5 and the base 1, in another embodiment of this application, the tail of the fixing seat 511 is a connecting end. The connecting end can be connected to the base 1 by fasteners to form a more stable connection and fixation effect, thereby strengthening the stability of the connection between the fixing seat 511 and the base 1.

[0067] In another embodiment, a stepper is disclosed, which may be referred to. Figure 3The stepper machines shown in the embodiments are largely the same, except that only one limiting pin 53 is provided. By manually adjusting the limiting pin 53 to insert into the first limiting hole 421 or the second limiting hole 311, the mode switching between "stepping up and down" and "twisting stepping left and right" can be realized.

[0068] The technical features of the embodiments described above can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.

[0069] The embodiments described above are merely examples of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these modifications and improvements all fall within the protection scope of this application.
