Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically to a handrail folding mechanism and a treadmill. Background Technology

[0002] With the improvement of people's living standards and the promotion of national fitness activities, the demand for treadmills is increasing. There are many types of treadmills available, among which foldable treadmills are more suitable for indoor use and are very popular. Currently, most treadmills on the market only allow folding of the upright column, not the handrails. This limits their use, as they lack the height and angle adjustment options for the handrails, failing to meet the needs of most users. Utility Model Content

[0003] To address at least one of the aforementioned problems, this utility model first provides a handrail folding mechanism, including a handrail, a locking / unlocking component, and a connecting seat and a mounting seat rotatably connected to each other. The connecting seat is fixedly connected to the handrail, and a first toothed ring is provided on the connecting seat. The locking / unlocking component includes a second toothed ring adapted to the first toothed ring. The locking / unlocking component is used to lock / unlock the connecting seat. When the connecting seat is locked, the first and second toothed rings are engaged and positioned. When the connecting seat is unlocked, the second toothed ring can slide away from the first toothed ring, so that an external force can drive the connecting seat to rotate.

[0004] Optionally, the locking and unlocking component includes a connecting rod and a locking block slidably sleeved on the connecting rod. The connecting rod passes through both the connecting seat and the mounting seat. The connecting seat rotates about the axis of the connecting rod. The second toothed ring is disposed on the locking block.

[0005] Optionally, a limiting opening is provided on one side wall of the mounting base, and a limiting step is provided on the side wall of the locking block. The locking block partially passes through the limiting opening and slides in the limiting opening. The limiting opening is used to restrict the rotation of the limiting step.

[0006] Optionally, the locking and unlocking component further includes a handle and a push block slidably sleeved on the connecting rod. The push block is in abutting connection with the locking block. The handle includes a hinge block that is hinged to the connecting rod. The hinge block is cam-shaped and rotates against the push block.

[0007] Optionally, the locking block has a recessed mounting cavity at one end near the pushing block, and a spring is installed in the mounting cavity, with the two ends of the spring abutting against the pushing block and the locking block respectively.

[0008] Optionally, the push block is provided with an abutment surface adapted to the hinge block, and the hinge block rotates and abuts against the abutment surface.

[0009] Optionally, the connecting seat includes a first connecting part, and the armrest is provided with a second connecting part. The first connecting part is detachably nested in the second connecting part. The first connecting part is provided with an elastic pressing block, and the second connecting part is provided with a pressing port suitable for accommodating the pressing block. When the pressing block is pressed, the first connecting part can be easily detached from the second connecting part.

[0010] Optionally, the mounting base is provided with limiting walls on both sides, and the connecting base is provided with two limiting blocks that are adapted to the limiting walls. The limiting blocks abut against the limiting walls to limit the rotation range of the connecting base.

[0011] Optionally, the angle between the axis of the handrail and the horizontal line is between 20 and 150 degrees.

[0012] Compared with the prior art, the handrail folding mechanism of this utility model has a detachable connecting seat on the handrail, which is rotatably connected to the mounting seat. At the same time, the locking and unlocking components cooperate with the connecting seat to fix the rotation angle, so that the handrail can rotate and fold relative to the mounting seat. Users can adjust the folding angle of the handrail according to their needs. The structure is simple and stable, and it is also easy to disassemble and store.

[0013] In addition, this utility model provides a treadmill, including the handrail folding mechanism as described above, and also includes a column. The mounting seat of the handrail folding mechanism is disposed at the upper end of the column, and the handrail of the handrail folding mechanism is folded relative to the column.

[0014] Compared with the prior art, the treadmill described in this utility model has the same advantages as the above-mentioned handrail folding mechanism, which will not be repeated here. Attached Figure Description

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0026] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0027] This utility model embodiment provides an armrest folding mechanism, combined with Figure 1-7 As shown, the device includes a handrail 1, a locking / unlocking component, a connecting seat 3 and a mounting seat 2 that are rotatably connected to each other. The connecting seat 3 is fixedly connected to the handrail 1. The connecting seat 3 is provided with a first toothed ring 32. The locking / unlocking component includes a second toothed ring 53 that is adapted to the first toothed ring 32. The locking / unlocking component is used to lock / unlock the connecting seat 3. When the connecting seat 3 is locked, the first toothed ring 32 and the second toothed ring 53 are engaged and positioned. When the connecting seat 3 is unlocked, the second toothed ring 53 can slide away from the first toothed ring 32 so that an external force can drive the connecting seat 3 to rotate.

[0028] like Figure 1As shown, in this embodiment, both ends of the handrail 1 are connected to the connecting seat 3, and the two connecting seats 3 are respectively connected to the two mounting seats 2, so that the rotation of the handrail 1 is more stable, and at the same time, it is convenient for the user's hands to support on the handrail 1.

[0029] The locking and unlocking components include a connecting rod 4 and a locking block 5 slidably sleeved on the connecting rod 4. The connecting rod 4 passes through both the connecting seat 3 and the mounting seat 2. The connecting seat 3 rotates around the axis of the connecting rod 4. The second toothed ring 53 is disposed on the locking block 5.

[0030] like Figure 3 and 6 As shown, the connecting seat 3 has a recessed mounting groove 31 at one end near the locking block 5, the first toothed ring 32 is disposed in the mounting groove 31, and the locking block 5 is partially accommodated in the mounting groove 31.

[0031] The armrest folding mechanism includes a locked state and an unlocked state. When locked, the locking block 5 engages with the connecting seat 3, the connecting seat 3 remains fixed relative to the mounting base 2, and the armrest 1 does not rotate relative to the mounting base 2. In this state, the user can support their hand on the armrest 1. When unlocked, the connecting seat 3 and the locking block 5 are not locked. Rotating the connecting seat 3, under the action of the inclined surface of the gear ring, pushes the locking block 5 away from the connecting seat 3, causing the first gear ring 32 and the second gear ring 53 to separate, allowing the connecting seat 3 to rotate relative to the mounting base 2, thereby causing the armrest 1 to rotate relative to the mounting base 2.

[0032] This utility model has a simple and stable structure, and is easy to disassemble and store, reducing the space occupied. Users can also adjust the folding angle of the armrest 1 according to their own needs.

[0033] Furthermore, such as Figure 6 and 7 As shown, a limiting opening 21 is provided on one side wall of the mounting base 2, and a limiting step 52 is provided on the side wall of the locking block 5. The locking block 5 partially passes through the limiting opening 21 and slides in the limiting opening 21. The limiting opening 21 is used to restrict the rotation of the limiting step 52.

[0034] The shape of the limiting opening 21 is adapted to the shape of the limiting step 52 to restrict the rotation of the locking block 5. Figure 6Taking the structure and orientation shown as an example, the limiting port 21 is composed of two semicircles with different diameters, and the centers of the two semicircles are the same. The limiting step 52 includes a first step 521 and a second step 522. The first step 521 is adapted to the upper semicircle, and the second step 522 is adapted to the lower semicircle. The first step 521 abuts against the upper semicircle to limit the sliding position of the locking block 5 on the connecting rod 4. The second step 522 slides through the lower semicircle and forms a limiting structure with the upper semicircle to prevent the locking block 5 from rotating under the drive of the connecting seat 3.

[0035] like Figure 3 and 6 As shown, the locking and unlocking components also include a handle 8 and a push block 7 slidably sleeved on the connecting rod 4. The push block 7 is in contact with the locking block 5. The handle 8 includes a hinge block 81 that is hinged to the connecting rod 4. The hinge block 81 is cam-shaped and rotates against the push block 7.

[0036] like Figure 3 As shown, in this embodiment, the position of the connecting rod 4 is fixed. The locking block 5 can be moved closer to the connecting seat 3 by pushing the pushing block 7 until the locking block 5 engages with the connecting seat 3.

[0037] The handle 8 has an open state and a closed state. When the handle 8 is nearly perpendicular to the connecting rod 4, it is in the closed state. At this time, the locking block 5 is engaged with the connecting seat 3, and the position of the connecting seat 3 relative to the mounting base 2 is fixed. When the handle 8 is nearly horizontal to the connecting rod 4, it is in the open state. At this time, the connecting seat 3 and the locking block 5 are not locked, and the connecting seat 3 can rotate relative to the mounting base 2.

[0038] The hinge block 81 cooperates with the push block 7. When the handle 8 is turned from the open state to the closed state, the hinge block 81 will push the push block 7 closer to the locking block 5, thereby making the locking block 5 engage with the connecting seat 3 and fix the position of the connecting seat 3 relative to the mounting seat 2.

[0039] When the handle 8 is turned from the closed state to the open state, the pushing force of the hinge block 81 on the push block 7 gradually disappears. The push block 7 can move away from the locking block 5 under the action of external force or the elastic force of the spring 6, thereby releasing the locking effect between the locking block 5 and the mounting base 2, so that the connecting base 3 can rotate relative to the mounting base 2.

[0040] The end of the connecting rod 4 away from the handle 8 is threaded. The connecting rod 4 is fixed to the mounting base 2 by a nut 41 to fix the position of the connecting rod 4. At the same time, when the locking block 5 engages with the connecting base 3, the nut 41 cooperates with the locking block 5 to clamp from both sides of the mounting base 2, so that the mounting base 2 further locks the connecting base 3 to fix the position of the connecting base 3.

[0041] like Figure 3 As shown, the locking block 5 has a recessed mounting cavity 51 at one end near the pushing block 7. A spring 6 is installed in the mounting cavity 51, and the two ends of the spring 6 abut against the pushing block 7 and the locking block 5, respectively.

[0042] The spring 6 provides power for the rebound of the push block 7. When the push block 7 pushes the locking block 5 by an external force, so that the locking block 5 engages with the connecting seat 3, the spring 6 is compressed.

[0043] In the above state, if the external force applied to the push block 7 is released, the spring 6 returns, and the push block 7 moves a short distance away from the locking block 5 under the elastic force of the spring 6. At this time, the second toothed ring 53 and the first toothed ring 32 are not locked. When the connecting seat 3 is rotated, the first toothed ring 32 will push the second toothed ring 53 towards the push block 7, so that the locking block 5 and the connecting seat 3 are separated, and the connecting seat 3 can rotate relative to the mounting base 2.

[0044] Preferably, such as Figure 3 As shown, the pushing block 7 is provided with an abutting surface adapted to the hinge block 81, and the hinge block 81 rotates and abuts against the abutting surface.

[0045] The abutting surface is formed by the pushing block 7 being recessed towards the end away from the locking block 5, and the abutting surface facilitates the hinge block 81 to push the pushing block 7. The connecting rod 4 has a larger diameter at the end near the pushing block 7 to prevent the pushing block 7 from disengaging from the connecting rod 4.

[0046] Preferably, the contact surface can be made of rubber to increase the friction when in contact with the hinge block 81, which facilitates the fixation of the handle 8.

[0047] like Figure 4As shown, the connecting seat 3 includes a first connecting part 33, and the armrest 1 is provided with a second connecting part 11. The first connecting part 33 is detachably nested in the second connecting part 11. The first connecting part 33 is provided with an elastic pressing block 34, and the second connecting part 11 is provided with a pressing port 12 suitable for accommodating the pressing block 34. When the pressing block 34 is pressed, the first connecting part 33 can be easily detached from the second connecting part 11.

[0048] Both the first connecting part 33 and the second connecting part 11 are hollow rod-shaped structures. The diameter of the first connecting part 33 is slightly smaller than the diameter of the second connecting part 11, so that the first connecting part 33 can be nested within the second connecting part 11. The first connecting part 33 and the second connecting part 11 can be fixed by means of bolt connection or snap-fit ​​connection. The cooperation between the first connecting part 33 and the second connecting part 11 facilitates the assembly and disassembly of the handrail 1 and the connecting seat 3, thereby facilitating storage and transportation and reducing space occupation.

[0049] In this embodiment, the pressing block 34 is disposed on the side wall of the first connecting part 33. When the first connecting part 33 is connected to the second connecting part 11, the pressing block 34 is located in the pressing port 12. The user can press the pressing block 34 to cause the side wall of the first connecting part 33 to elastically deform inward, thereby loosening the connection between the first connecting part 33 and the second connecting part 11, making it easier to disassemble.

[0050] like Figure 5 As shown, the mounting base 2 has limiting walls 22 on both sides, and the connecting base 3 has two limiting blocks 35 that are adapted to the limiting walls 22. The limiting blocks 35 abut against the limiting walls 22 to limit the rotation range of the connecting base 3.

[0051] The limiting wall 22 and the limiting block 35 cooperate to limit the rotation range of the connecting seat 3 relative to the mounting seat 2, thereby further limiting the folding angle of the handrail 1, making the folding angle of the handrail 1 more suitable for the user.

[0052] In this embodiment, the angle between the axis of the handrail 1 and the horizontal line is between 20 and 150 degrees. The handrail 1 being positioned within this angle range is more suitable for user use and conforms to ergonomics.

[0053] Furthermore, a mobile phone holder can be installed on the handrail 1, and when using the handrail 1, the user can adjust the angle of the handrail 1 according to their own visual preferences.

[0054] Another embodiment of the present invention provides a treadmill, including the handrail folding mechanism as described above, and also including a column 9. The mounting base 2 of the handrail folding mechanism is disposed at the upper end of the column 9, and the handrail 1 of the handrail folding mechanism is rotated and folded relative to the column 9.

[0055] In this embodiment, the lower end of the column 9 can be rotated and folded to reduce space occupation and facilitate transportation. There are two columns 9, and each column 9 is fixed with a mounting base 2. Through the cooperation between the mounting base 2 and the connecting base 3, the two ends of the handrail 1 are respectively rotatably connected to the two columns 9.

[0056] Although the disclosure is as stated above, the scope of protection of this disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of this disclosure, and all such changes and modifications will fall within the protection scope of this utility model.
