Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of sports equipment, especially a dual-function treadmill. BACKGROUND

[0002] With the improvement of people's health consciousness, the demand for fitness equipment is increasing. As a common indoor fitness equipment, the treadmill is widely welcomed because it can simulate the action of climbing stairs or walking, helping users to exercise lower limb muscles and improve cardiopulmonary function. However, most of the existing treadmills only support a single up-and-down stepping mode, and the function is relatively single, which cannot meet the needs of users for diversified exercise experience. In addition, the single exercise mode is easy to make users feel boring after a long time of use, and cannot fully exercise the core muscle group and body coordination.

[0003] In recent years, some treadmills that attempt to introduce diversified exercise modes have appeared on the market, such as adjusting the angle of the tread plate manually or replacing parts to achieve different exercise ways. However, these designs have obvious limitations: first, the operation is complex, users need to manually adjust or replace parts, which not only takes time and effort, but also may cause equipment damage or safety hazards due to improper operation; second, the structure is complex, which increases the manufacturing cost and maintenance difficulty of the equipment. (Refer to "201420359929.9 - A new type of treadmill" utility model patent)

[0004] To solve the above problems, the utility model provides a treadmill with a switching structure for "up-and-down stepping" and "left-and-right twisting stepping" two exercise modes, realizing quick and convenient switching between the two modes. UTILITY MODEL CONTENTS

[0044] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0045] 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.

[0046] 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 invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0047] refer to Figures 1 to 8 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.

[0048] 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.

[0049] 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 connected to the rotating shaft 11. The two "rotating components" have different structures. For the sake of simplicity in the embodiment, they are all described as "rotating components".

[0050] refer to Figure 7 and Figure 8 , combined Figure 5 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.

[0051] refer to Figure 5 and Figure 6 , combined Figure 5 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.

[0052] The stepper in this embodiment also includes a sliding locking mechanism 5, which includes a sliding pin 51 and a limiting plate 52. The limiting plate 52 is connected to and fixed to the end of the rotating shaft 11 away from the base 1. The limiting plate 52 has a guide hole 521 that matches the sliding pin 51, and the sliding pin 51 slides along the guide hole 521.

[0053] Specifically, one end of the rotating shaft 11 connected to the limiting plate is detachably connected to the limiting plate 52, and the limiting plate 52 is locked in place. The connection between the two can be a key connection, or a polygonal locking structure can be provided at the end of the rotating shaft and coupled with a polygonal hole provided on the limiting plate for locking.

[0054] The foot pedal connecting mechanism 3 has a first limiting slot 311 on its rotating component, and the linkage mechanism 4 has a second limiting slot 421 on its rotating component. One end of the guide hole 521 corresponds to the first limiting slot 311, and the other end of the guide hole 521 corresponds to the second limiting slot 421. The sliding pin 51 slides between the two ends of the guide hole 521, thereby fixing the rotating component of the linkage mechanism 4 to the base 1 and the rotating component of the foot pedal connecting mechanism 3 to the base 1, and realizing the conversion between the "left and right twisting step" and "up and down step" movement modes.

[0055] refer to Figure 2 and Figure 3 In one embodiment of the present invention, the sliding locking mechanism 5 further includes a sliding pin cover 53, which is connected to the upper end of the limiting plate 52, and the two form an active cavity 54.

[0056] Furthermore, the sliding pin 51 is movable within the movable cavity 54. The sliding pin 51 includes a sliding pin body 513, which slides along the upper end face of the limiting plate 52. The lower end face of the sliding pin cover 53 abuts against the sliding pin body 513, limiting the relative distance between the sliding pin body 513 and the limiting plate 52, and preventing the sliding pin body 513 from moving away from the limiting plate 52.

[0057] Furthermore, the sliding pin 51 partially passes through the sliding pin cover 53 to form a driving end 511, and the sliding pin 51 partially passes through the limiting plate 52 to form a locking end 512. The driving end 511 is used to drive the sliding pin body 513 to move in the movable cavity 54, and the locking end 512 is used to lock with the first limiting slot 311 and the second limiting slot 421.

[0058] It should be noted that the guide hole 521 guides the movement of the sliding pin 51 within the movable cavity 54. The guide hole 521 can be provided on the sliding pin cover 53 to guide the driving end 511, or it can be provided on the limiting plate 52 to guide the locking end 512.

[0059] refer to Figures 2 to 4 In some embodiments, the locking end 512 includes a first locking end 512a and a second locking end 512b, which are respectively disposed at both ends of the movement direction of the locking end 512.

[0060] When the locking end 512 moves to one end of the guide hole 521, the first locking end 512a enters the first limiting groove 311 to form a lock, and the second locking end 512b leaves the second limiting groove 421.

[0061] When the locking end 512 moves to the other end of the guide hole 521, the second locking end 512b enters the second limiting slot 421 to form a lock, and the first locking end 512a leaves the first limiting slot 311.

[0062] Among them, such as Figure 3 As shown, the opening direction of the first limiting slot 311 is opposite to the opening direction of the second limiting slot 421. However, it is not excluded that the opening directions of the two slots may be opposite.

[0063] In another embodiment, the opening direction of the first limiting slot 311 is set opposite to the opening direction of the second limiting slot 421, and the locking end 512 moves between the first limiting slot 311 and the second limiting slot 421 to switch motion modes.

[0064] refer to Figure 3 and Figure 4 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.

[0065] The foot pedal assembly 2 includes a pedal 21, a pedal bracket 22 for fixing the pedal 21, and a hydraulic rod 23;

[0066] 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;

[0067] 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.

[0068] 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.

[0069] For specific usage, please refer to... Figures 5 to 8 When the user steps on the pedal 21, the pedal frame 22 rotates around the pivot end 221, and the swing end 222 presses the hydraulic rod 23.

[0070] refer to Figure 5 and Figure 6During the "stepping up and down" movement, the foot pedal connecting mechanism 3 is relatively fixed to the base 1 by the sliding locking mechanism 5, and the lever 41 is driven by the pivot end 221 to drive the foot pedal assembly 2 to swing the linkage plate 42.

[0071] refer to Figure 7 and Figure 8 During the "left and right twisting stepping" movement, the linkage plate 42 is relatively fixed to the base 1 by the sliding 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.

[0072] Furthermore, the first limiting slot 311 is provided on the rocker arm 31, and the second limiting slot 421 is provided on the connecting piece 42.

[0073] refer to Figure 9 and Figure 10 To enhance the connection strength between the sliding locking mechanism 5 and the base 1, in another embodiment of this application, the tail of the limiting plate 52 is a connecting end. This connecting end can be connected to the base 1 by fasteners, which can prevent the limiting plate 52 from engaging with the rotating shaft 11, thus forming a more stable connection and fixing effect.

[0074] 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.

[0075] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
