Description

Technical Field

[0001] This utility model relates to a fitness equipment, and more particularly to a folding structure for the side handrail of a treadmill. Background Technology

[0002] As living standards continue to improve, people are paying more and more attention to physical exercise, and running is the simplest and most effective way to stay fit, making treadmills increasingly popular. For easier storage, some users choose foldable treadmills, which can be folded for storage to save space.

[0003] However, traditional folding treadmills typically only lift the running platform upwards for storage, resulting in limited space savings. Even existing folding treadmills with hinged front and rear running platforms only fold up the rear platform to cover the front platform, further limiting space savings, and the front platform still occupies a significant area. Some folding treadmills can fold the handrails, but most folding methods are vertical. After folding, the handrails protrude because their length exceeds the running platform length, still taking up space and failing to meet user needs. While some handrail folding methods are horizontal, their complex structures are unreliable. Therefore, this application proposes a folding structure for the side handrails of treadmills, which offers faster folding and storage and a stable and reliable structure after folding. Utility Model Content

[0004] This utility model provides a folding structure for the side handrail of a treadmill, which enables quick and convenient folding and storage of the treadmill's side handrail while maintaining reliable self-locking. The specific technical solution is as follows:

[0005] A folding structure for a treadmill side handrail includes a front support frame connected to the running platform. A handrail assembly is hinged to the top of the front support frame. The handrail assembly can rotate horizontally relative to the front support frame to be in an unfolded or retracted state. A self-locking component is provided inside the handrail assembly to lock the handrail assembly in both the unfolded and retracted states. The self-locking component includes a retractable adjusting shaft connected to an elastic element. The front support frame is provided with a first limiting hole and a second limiting hole. When the handrail assembly is in the unfolded or retracted state, the adjusting shaft can be inserted into the first or second limiting hole under the drive of the elastic element to achieve self-locking. A button is provided inside the handrail assembly and is connected to the adjusting shaft. The button can drive the adjusting shaft to retract to achieve unlocking.

[0006] Furthermore, a fixing sleeve is fixedly installed at the end of the handrail assembly near the front support frame, and a handrail pivot is inserted into the fixing sleeve. The handrail pivot is screwed to the front support frame to achieve the hinge connection between the handrail assembly and the front support frame.

[0007] Furthermore, an upper support plate and a lower support plate are fixedly installed horizontally at intervals on the front support frame, forming a space between the upper support plate and the lower support plate for the handrail assembly to move. The handrail pivot passes through the upper support plate and the fixing sleeve in sequence and is screwed to the lower support plate.

[0008] Furthermore, a rotating plate is fixedly installed on the inner side of the lower support plate, with a first limiting hole on the lower support plate and a second limiting hole on the rotating plate.

[0009] Furthermore, an adjusting sleeve is provided inside the handrail assembly near the fixed sleeve, an elastic element is provided inside the adjusting sleeve, and an adjusting shaft is inserted into the adjusting sleeve and can slide up and down relative to the adjusting sleeve.

[0010] Furthermore, an elongated hole is vertically provided on the adjusting sleeve, and the button is connected to the adjusting shaft inside the adjusting sleeve through the elongated hole.

[0011] Furthermore, the end of the button that is away from the adjustment shaft is hinged to the armrest assembly, and a protrusion for the user to press is provided in the middle of the button, which is located on the outside of the armrest assembly.

[0012] Furthermore, the fixed sleeve is connected to the limiting component, which can limit the rotation angle of the fixed sleeve.

[0013] Furthermore, a limiting groove is provided below the fixed sleeve, and a limiting post is provided on the lower support plate, with the end of the limiting post accommodated in the limiting groove.

[0014] Furthermore, the front support frame includes a column tube, the top of which is fixedly connected to a fixed tube, an upper support plate is fixedly mounted on the fixed tube, and a lower support plate is fixedly mounted on the column tube.

[0015] This utility model features an ingenious structural design. It achieves self-locking by inserting a retractable elastic adjustment shaft into a limiting hole, ensuring safe and reliable locking. Unlocking is achieved by pressing a button, allowing the handrail assembly to switch between extended and retracted states. This design is convenient, quick, and highly compact in the retracted state, significantly reducing the space occupied by the fitness equipment. Furthermore, the inclusion of limiting posts effectively prevents the handrail assembly from folding backward or over-traveling inward, ensuring a superior user experience.

[0016] The above description is merely an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of this utility model more obvious and understandable, specific embodiments of this utility model are given below.

[0023] To better understand the purpose, function, and specific design of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of the folding structure of the treadmill side handrail.

[0024] like Figure 1-5 As shown, the folding structure of the treadmill side handrail of this utility model includes a front support frame 1 connected to the running platform. A handrail assembly 2 is hinged to the upper part of the front support frame 1. The handrail assembly 2 can rotate horizontally relative to the front support frame 1 to be in an unfolded or retracted state. A self-locking component 3 is provided inside the handrail assembly 2, which can lock the handrail assembly 2 in the unfolded and retracted states. The self-locking component 3 includes a retractable adjusting shaft 31 connected to an elastic element 33. The front support frame 1 is provided with a first limiting hole 41 and a second limiting hole 42. When the handrail assembly 2 is in the unfolded or retracted state, the adjusting shaft 31 can be inserted into the first limiting hole 41 or the second limiting hole 42 under the drive of the elastic element 33 to achieve self-locking. A button 5 is provided inside the handrail assembly 2. The button 5 is connected to the adjusting shaft 31. The button 5 can drive the adjusting shaft 31 to retract to achieve unlocking.

[0025] Specifically, a fixing sleeve 61 is fixedly installed at the end of the handrail assembly 2 near the front support frame 1. A handrail pivot 62 is inserted into the fixing sleeve 61 and screwed to the front support frame 1 to achieve a hinged connection between the handrail assembly 2 and the front support frame 1. In this embodiment, an upper support plate 11 and a lower support plate 12 are fixedly installed horizontally at intervals on the front support frame 1. A space for the handrail assembly 2 to move is formed between the upper support plate 11 and the lower support plate 12. The handrail pivot 62 passes through the upper support plate 11 and the fixing sleeve 61 in sequence and is screwed to the lower support plate 12. By setting the upper support plate 11 and the lower support plate 12, the handrail assembly 2 can be vertically limited, thereby making the handrail assembly 2 more stable when rotating in the horizontal direction, and also reducing the shear force between the handrail pivot 62 and the fixing sleeve 61, thereby extending the service life of the handrail pivot 62 and the fixing sleeve 61.

[0026] In this embodiment, a rotating plate 13 is fixedly provided on the inner side of the lower support plate 12, a first limiting hole 41 is provided on the lower support plate 12, and a second limiting hole 42 is provided on the rotating plate 13.

[0027] like Figure 3-4 As shown, an adjusting sleeve 32 is provided inside the armrest assembly 2 near the fixed sleeve 61. An elastic element 33 is disposed inside the adjusting sleeve 32. In this embodiment, the elastic element 33 is a spring. The adjusting shaft 31 is inserted into the adjusting sleeve 32 and can slide up and down relative to the adjusting sleeve 32 to achieve self-locking of the adjusting shaft 31. A vertically arranged elongated hole is provided on the adjusting sleeve 32, and the button 5 is connected to the adjusting shaft 31 inside the adjusting sleeve 32 through the elongated hole. By pressing the button 5, the button 5 moves up and down relative to the elongated hole, thereby driving the adjusting shaft 31 to move up and down to achieve unlocking.

[0028] Preferably, in order to facilitate pressing the button 5, the end of the button 5 away from the one connected to the adjustment shaft 31 is hinged to the armrest assembly 2, and a protrusion for the user to press is provided in the middle of the button 5, and the protrusion is located on the outside of the armrest assembly 2.

[0029] It is worth noting that, in order to prevent the armrest assembly 2 from folding backward or over-travel inward, the fixing sleeve 61 in this embodiment is connected to the limiting assembly, which can limit the rotation angle of the fixing sleeve 61. Specifically, a limiting groove 611 is provided below the fixing sleeve 61, and a limiting post 7 is provided on the lower support plate 12. The end of the limiting post 7 is accommodated in the limiting groove 611, and the limiting post 7 can limit the rotation angle of the fixing sleeve 61.

[0030] In addition, in order to facilitate the installation of the handrail assembly 2 and to leave space for the crossbeam of the front support frame 1 to facilitate the installation of components such as the screen, the front support frame 1 of this embodiment includes a column tube 15. The top of the column tube 15 is fixedly connected to the fixed tube 14, the upper support plate 11 is fixedly mounted on the fixed tube 14, and the lower support plate 12 is fixedly mounted on the column tube 15.

[0031] This utility model features an ingenious structural design. It achieves self-locking by inserting a retractable elastic adjustment shaft into a limiting hole, ensuring safe and reliable locking. Unlocking is achieved by pressing a button, allowing the handrail assembly to switch between extended and retracted states. This design is convenient, quick, and highly compact in the retracted state, significantly reducing the space occupied by the fitness equipment. Furthermore, the inclusion of limiting posts effectively prevents the handrail assembly from folding backward or over-traveling inward, ensuring a superior user experience.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
