Description

Technical Field

[0001] This invention relates to the field of fitness equipment technology, specifically to a parallel folding treadmill and its application. Background Technology

[0002] Treadmills are a popular and widely used fitness equipment in homes. However, their large size makes them difficult to store and less suitable for families with limited indoor space. Furthermore, their large size increases transportation costs during shipping. Summary of the Invention

[0003] To address the aforementioned technical issues, a treadmill with a compact and stable structure after folding and its application are provided.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a parallel folding treadmill, comprising a first running board and a second running board that are separately set up, and the two are connected by a sliding linkage mechanism, so that the second running board is folded parallel to the top of the first running board, thereby realizing the parallel folding of the treadmill.

[0005] According to the present invention, it further includes a first frame for supporting the first running board and a second frame for supporting the second running board. The first frame has a guide rail extending along the length direction of the first frame on at least one side surface, and a linkage mechanism that cooperates with the guide rail and reciprocates along its extension direction. The linkage mechanism is connected to the second running board and drives the second running board to move parallel to the first running board above it along its length direction.

[0006] According to the present invention, the linkage mechanism further includes a first link that cooperates with the guide rail and slides back and forth along the extension direction of the guide rail. The other end of the first link is hinged to the second running plate. A second link is also hinged to the same side of the second running plate. The other end of the second link is hinged to the first link, forming a stable linkage mechanism.

[0007] According to the present invention, the second link is further hinged to the middle position of the first link.

[0008] According to the present invention, the length of the guide rail is shorter than the length of the first frame.

[0009] According to the present invention, a sliding linkage mechanism is further provided on both opposite sides of the first frame.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] This invention achieves folding operation through manual lifting, pushing, and placing. The operation process is simple and can be operated by a single person. The folded treadmill is smaller in size and easier to store. For manufacturers, transporting it in the folded state reduces transportation costs due to its smaller size.

[0012] The linkage assembly and guide rail of the present invention work together to ensure that the components are subjected to uniform force during folding, thereby improving the folding stability of the treadmill. Attached Figure Description

[0016] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0017] like Figure 1 and Figure 2 As shown in the figure, this application discloses a parallel folding treadmill, including a bottom frame 100, a running board assembly 200 disposed on the top of the bottom frame 100, and a running belt 300 covering the top surface of the running board 200 and wrapped around the front and rear drive structure of the treadmill; wherein, the running board assembly 200 includes a first running board 210 and a second running board 220 disposed on one side end face thereof, which are connected by a sliding linkage mechanism. The second running board 220 is manually lifted and slid parallel above the first running board 210 through the sliding linkage mechanism until it is placed on top of the first running board 210, thereby realizing the parallel folding of the treadmill by manual means.

[0018] The bottom frame 100 includes a first frame 110 disposed at the bottom of the first running plate 210 and a second frame 120 disposed at the bottom of the second running plate 220. At least one side surface of the first frame 110 is provided with a guide rail 111 extending along the length direction of the first frame 110, and the length of the guide rail 111 is shorter than the length of the first frame 111. A first connecting rod 400 cooperates with the guide rail 111 and slides back and forth along the extension direction of the guide rail 111. The other end of the first connecting rod 400 is hinged to the side surface of the second running plate 220. At the same time, a second connecting rod 500 is also hinged to the side surface of the second running plate 200, and the other end of the second connecting rod 500 is hinged to the middle position of the first connecting rod 400, forming a stable linkage mechanism.

[0019] In this embodiment, the first frame 110 is provided with sliding linkage mechanisms on both opposite sides to maintain the stability of parallel movement.

[0020] The working principle of this invention is as follows:

[0021] Folding process: Lift the free end of the second running plate 220 upwards, and the first connecting rod 400 gradually deflects to a vertical state as the second running plate 220 rotates;

[0022] Push the second running plate 220 towards the first running plate 210. At this time, the slider of the first connecting rod 400 slides along the long strip guide rail 111 towards the end of the first running plate 210 away from the second running plate 220. The second connecting rod 500 adapts to the angle simultaneously to maintain structural stability.

[0023] After the first link 400 slides along the guide rail 111 to the preset position, the second running plate 220 is gently placed downwards so that it fits flat against the top surface of the first running plate 210, thus completing the folding.

[0024] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed invention.
