Description

Technical Field

[0001] This invention relates to the field of treadmill technology, and in particular to a folding structure for treadmill handrails. Background Technology

[0002] Treadmill handrails can be used to increase safety during running. Whether you're looking at your phone or turning your head to check the side or back, you can put your hands on the handrails to prevent accidentally stepping into a hole or veering off course.

[0003] With market development, treadmills with foldable armrests are becoming more popular among users, as they are easier to store than conventional treadmills.

[0004] As shown in the published patent document CN107866035A, a folding structure for the handrail of a treadmill is a common form on the market. The handrail can be limited after being rotated to a set angle so that the user can hold on or lean against it. However, in this structure, the support force is all supported by a small part at the rotating connection, which is difficult to withstand large pressure and is easily damaged when subjected to large pressure. Therefore, the applicant has made further improvements. Summary of the Invention

[0005] This invention addresses the shortcomings of existing technologies by providing a folding structure for treadmill handrails. This folding method provides a more reasonable force distribution, making it more stable and robust. According to preliminary tests, it can stably support an adult male weighing around 200 pounds regardless of the form of downward pressure.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] The folding structure of the treadmill handrails includes...

[0014] The second unit has a second receiving position formed at one end connected to the first unit, and the second receiving position includes a third wall, a fourth wall and a second arm;

[0015] The first arm is disposed at the second receiving position, and the second arm is disposed at the first receiving position;

[0016] When the second unit is in the first position, the first wall and the third wall are in a limiting engagement, and at the same time, the second wall and the fourth wall are in a limiting engagement.

[0017] In the above scheme, preferably, the first unit is provided with a through-limiting groove, and the second unit is provided with a limiting post that moves on the through-limiting groove. When the limiting post moves to the two ends of the through-limiting groove, it corresponds to the first position and the second position of the first unit, respectively.

[0018] In the above scheme, preferably, a buffer pad is provided on the wall where the first unit and the second unit are in contact.

[0019] In the above scheme, preferably, the second unit includes a first connecting arm, a panel arm and a second connecting arm connected in sequence.

[0035] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

[0036] See Figures 1-8 The treadmill handrail folding structure includes a first unit 1 and a second unit 2.

[0037] The first unit 1 is disposed on both sides of the running platform (not shown in the figure) and is rotatably connected to the running platform. The rotatable connection structure and related locking structure between the first unit 1 and the running platform can be any form in the existing design.

[0038] The second unit 2 is rotatably mounted on the first unit 1. In this embodiment, the second unit 2 includes a first connecting arm 21, a panel arm 22, and a second connecting arm 23 connected in sequence, as follows: Figure 1 , Figure 3As shown, the first connecting arm 21 and the second connecting arm 23 are symmetrically arranged at both ends of the panel arm 22. The first connecting arm 21 and the second connecting arm 23 are respectively used for rotatable connection with the corresponding first unit 1, forming a shape after assembly as shown. Figure 1 , Figure 6 The state shown, where, Figure 1 This is the second unit in its unfolded state, providing support and a place for users to lean on. Figure 6 The second unit 2 is in the folded state. In this state, the arm of the second unit 2 is aligned with the arm of the first unit 1, so that the whole can be folded down to be flush with or close to being flush with the running platform, so that the whole can be folded.

[0039] Based on the typical usage pattern of users, their hands are usually placed on the first connecting arm 21 and the second connecting arm 23 respectively. Considering the common shape of the hands at this time, the thumbs are usually suspended or downward on one side, and the thumbs are located in the space between the first connecting arm 21 and the second connecting arm 23. More specifically, the two thumbs are usually closer to the inner wall of the first connecting arm 21 and the inner wall of the second connecting arm 23. Therefore, this application design places the control switch 3 on the inner wall of the first connecting arm 21 and / or the second connecting arm 23. The control switch 3 can be a function adjustment switch or an emergency stop switch, such as a speed increase switch on one side and a speed decrease switch on the other side. The operation method can be button type, touch screen type, etc.

[0040] Regarding the rotatable connection between the second unit 2 and the first unit 1, in this embodiment, the first unit 1 is provided with a through-hole limiting groove 4, such as... Figure 5 As shown. The second unit 2 is equipped with a limiting post 5 that moves within the through-slot 4, as... Figure 4 As shown.

[0041] like Figure 4 , Figure 5 , Figure 7 The through-slot 4 shown has two ends, and the limiting post 5 can move along the wall of the through-slot 4 between the two ends. When the limiting post 5 is located at the two ends of the through-slot 4, it corresponds to the first position and the second position of the second unit 2, respectively. The first position refers to the position of the second unit 2 when it is in the unfolded state, as shown in the figure. Figure 1 As shown; the second position refers to the position of the second unit 2 when it is in the folded state, as shown in the figure. Figure 6 As shown.

[0042] The upper end of the first unit 1 has a through hole 11, such as Figure 5 As shown, the through hole 11 is located on the side of the through limiting groove 4. The second unit 2 is equipped with an assembly head 61. After the assembly head 61 passes through the through hole 11, it is connected to an assembly part 62 with an outer diameter larger than the through hole 11, so that the first unit 1 is connected to the second unit 2, and the second unit 2 can rotate around the connection point. A certain damping can be set when rotating.

[0043] As one implementation method, such as Figure 8 As shown, the assembly head 61 and the assembly part 62 can be connected by threads. At the same time, several shims can be set between the assembly part 62 and the inner wall of the first unit 1. For example, the damping of the second unit 2 when rotating around the first unit 1 can be adjusted by adjusting the thread tightness of the assembly head 61 and the assembly part 62.

[0044] The fit between the through-limiting groove 4 and the limiting post 5, and the fit between the assembly head 61 and the wall of the through hole 11, can play a certain role in limiting and supporting. However, this role in limiting and supporting is not prominent enough compared with the existing design. In this application, the following structural design is also provided to enhance the role in limiting and supporting, so that the treadmill handrail has a sufficiently stable and firm supporting effect.

[0045] In this embodiment, the limiting and supporting structure is mainly reflected in the unfolded state of the second unit 2. In this state, there are two limiting and supporting structures. Using any one of them can greatly improve the stability and firmness of the support, and using both of them can further improve it.

[0046] Overall, the first unit 1 has a wall for maintaining the second unit 2 in the first position.

[0047] Specifically, the upper ends of both first units 1 are formed with first receiving positions 7, which include a first wall 71, a second wall 72 and a first arm 73; correspondingly, on the second unit 2, the outer ends of the first connecting arm 21 and the second connecting arm 23 are formed with second receiving positions 8, which include a third wall 81, a fourth wall 82 and a second arm 83.

[0048] like Figures 1-3 As shown, the first arm 73 is disposed at the second receiving position 8, and the second arm 83 is disposed at the first receiving position 7. The first receiving position 7 can be understood as having a notch opened on one side of the upper end of the first unit 1, or as being formed by extending the upper half of the first unit 1 upwards. The second receiving position 8 is similar.

[0049] The first unit 1 and the second unit 2 work together so closely that the first wall 71 on the first unit 1 can engage with the third wall 81 on the second unit 2 for limiting; the second wall 72 on the first unit 1 can engage with the fourth wall 82 on the second unit 2 for limiting. That is, when the second unit 2 is in the first position, the first wall 71 and the second wall 72 can simultaneously limit and support the second unit 2. Combined with the direction of the force exerted by the user when holding or leaning on the second unit 2, the above design allows the first unit 1 and the second unit 2 to work together to bear the force, thus providing stable and firm support. According to actual tests, even users weighing over 200 catties can be supported stably and firmly by using both hands to support the second unit, no matter how much they sway back and forth.

[0050] To improve the user's comfort when the second unit 2 is in the unfolded state, the first wall 73 can be designed as a slope so that the second unit 2 is tilted downwards when it is in the first position. Of course, the fourth wall 82 on the second unit 2 can also be designed as a slope to match the slope of the first wall 73.

[0051] To reduce or eliminate the noise caused by the collision between the second unit 2 and the first unit 1, a buffer pad 9 can be provided on the wall where the first unit 1 and the second unit 2 are in contact. For example, a buffer pad can be provided on the fourth wall 82 of the second unit 2 or on the second wall 72 of the first unit 1. Of course, the buffer pad is preferably provided on the fourth wall 82 of the second unit 2 so that it is not exposed when the second unit 2 is folded up.

[0052] In this application, when the second unit 2 is in the first position in the unfolded state, it can be used by any user. For taller users, the second unit 2 can be rotated to the second position. Since the second unit 2 also has a limit when folded and the damping design is in effect, the user can also hold or lean on the second unit 2 in this state. This handrail folding structure provides two holding and leaning modes, which can be freely selected according to the user's needs.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention 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 the present invention.
