Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, and in particular to a rotating structure for an instrument handrail and a treadmill. Background Technology

[0002] Treadmills are a common fitness equipment in daily life. They generally include a treadmill body and a column set on the treadmill body. Some treadmills also have handrails or instruments on the column, such as the patent document CN220142527U, which describes a treadmill handrail folding mechanism and a treadmill.

[0003] To facilitate the storage of the treadmill and reduce the storage space or packaging space required after the treadmill is stored, the aforementioned published documents design the handrails to be foldable, meaning that the handrails can rotate relative to the uprights so that they are within the height range of the treadmill body after being folded.

[0004] In the prior art, no method of rotating and folding the instrument is disclosed. Therefore, common treadmills design the instrument to be as small as possible, as described in the above-mentioned disclosures, in order to reduce the longitudinal space occupied by the treadmill when it is in the folded state. Based on this, the applicant files this application. Utility Model Content

[0005] This utility model addresses the shortcomings of existing technologies by providing a rotating instrument armrest structure and a treadmill. Both the armrest unit and the instrument unit are designed to rotate relative to the column unit, so as to minimize the space occupied by the treadmill in the longitudinal direction when folded.

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

[0007] A rotating structure for an instrument handrail includes a column unit and a handrail unit and an instrument unit that are rotatably mounted on the column unit without affecting each other. A limit rod is provided on the column unit to limit the handrail unit and / or the instrument unit.

The handrail unit and the instrument unit are respectively rotatably disposed at both ends of the rotating shaft.

[0012] In the above technical solution, preferably, the mounting hole includes a plurality of first limiting planes, and the rotating shaft includes a plurality of second limiting planes adapted to the first limiting planes, so that the rotating shaft cannot rotate relative to the mounting hole through the cooperation of the first limiting planes and the second limiting planes.

[0013] In the above technical solution, preferably, one end of the rotating shaft includes a limiting flange for limiting the instrument unit, and the other end is threadedly connected to a nut for limiting the armrest unit.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments:

[0030] See Figures 1-9 A rotating structure for an instrument armrest includes a column unit 1 and armrest units 2 and instrument units 3, which are rotatably mounted on the column unit 1 without affecting each other. The rotatability means that the instrument unit 3 is not affected when the armrest unit 2 rotates, and the armrest unit 2 is not affected when the instrument unit 3 rotates. The rotation of the two is independent. After rotation, the armrest unit 2 is limited and supported by a limit rod 6 mounted on the column unit 1 to avoid the problem that the instrument unit 3 may be rotated together with the armrest unit 3 when the armrest unit 2 is rotated, and the armrest unit 3 may be rotated together with the armrest unit 3 when the armrest unit 2 is rotated, which may require multiple adjustments to achieve the desired rotation angle.

[0031] For the column unit 1, its general shape can refer to the existing design and be arranged on the left and right sides of the treadmill body 4. It can be placed directly on the ground on the left and right sides of the treadmill body 4, or it can be rotatably set on the left and right side walls of the treadmill body 4. Of course, the rotating structure of the instrument handrail in this application can also be applied to the style where the column unit is fixedly set on the treadmill body.

[0032] The difference between the column unit 1 in this application and existing designs lies in the design of its connection with the armrest unit 2 and the instrument unit 3. The column unit 1 can be as follows: Figure 9 The design shown has two variations, which are respectively mounted on the left and right side walls of the treadmill body.

[0033] The upper end of the column unit 1 is provided with a mounting hole 11. A rotating shaft 5 is non-rotatably inserted through the mounting hole 11. The mounting hole 11 includes a plurality of first limiting planes 111. The first limiting planes 111 are part of the hole wall of the mounting hole 11. They are non-circular walls, such as flat walls. In one embodiment, except for the first limiting planes 111, the shape of the remaining hole walls of the mounting hole 11 is circular. It can be understood that the mounting hole 11 is a hole in which part of the hole wall of a circular hole is changed to a flat wall. The mounting hole 11 can be directly formed on the upper end of the column unit 1 or formed on a molded part, and the molded part is fixed on the upper end of the column unit 1.

[0034] The outer wall shape of the rotating shaft 5 is adapted to the mounting hole 11. It includes several second limiting planes 51 adapted to the first limiting plane 111. Except for the second limiting planes 51, the rest of the parts can be designed to be circular so that the rotating shaft 5 cannot be rotated after being installed in the mounting hole 11, while providing a position for the armrest unit 2 and the instrument unit 3 to rotate on the rotating shaft 5.

[0035] In this embodiment, after the rotating shaft 5 passes through the mounting hole 11, its two ends are exposed on the left and right sides of the column unit 1. The handrail unit 2 and the instrument unit 3 are respectively rotatably disposed at the two ends of the rotating shaft 5, so that the handrail unit 2 and the instrument unit 3 can rotate and fold relative to the column unit 1.

[0036] In this embodiment, one end of the rotating shaft 5 includes a limiting flange 52 for limiting the instrument unit, and the other end is threadedly connected to a nut 53 for limiting the handrail unit 2.

[0037] Specifically, a through hole 321 is provided on the support arm 32 of the frame 31 of the instrument unit 3. The size of the through hole 321 is adapted to the outer diameter of the rotating shaft 5, but smaller than the outer diameter of the limiting flange 52, so that the support arm 32 can be assembled on the rotating shaft 5 and rotate on the rotating shaft, but is limited by the limiting flange 52, so that it is limited to the upper end of the column unit 1 between the limiting flange 52.

[0038] The handrail unit 2 includes a handrail tube 21 and a sleeve 22 fixed to one end of the handrail tube 21. The sleeve 22 includes an inner cavity 221 with one end open and a connecting hole 222 that communicates with the inner cavity 221 and is adapted to the rotating shaft 5. The connecting hole 222 is similar to the through hole 321 on the arm. Its size is adapted to the outer diameter of the rotating shaft 5, but smaller than the outer diameter of the nut 53, so that the handrail unit 2 can be assembled on the rotating shaft 5 and rotate on the rotating shaft 5, but is restricted by the nut 53, so that it is limited to the upper end of the column unit 1 between the nut 53. After the handrail unit 2 is assembled, the nut 53 is arranged in the inner cavity 221 to form a hidden design, and the inner cavity 221 can be sealed by a cover plate.

[0039] Regarding how to limit the handrail unit 2 and the instrument unit 3, in this embodiment, a limiting rod 6 is provided at the upper end of the column unit 1. For example, a hole adapted to the limiting rod 6 is opened on the side of the mounting hole 11 on the column unit 1, and the limiting rod 6 passes through the hole with both ends exposed; or the limiting rod 6 with both ends exposed is integrally formed on the column unit 1; or the limiting rod 6 with both ends exposed is welded on the column unit 1.

[0040] Regarding the limiting of the handrail unit 2, in this embodiment, a limiting block 23 that rotates synchronously with the handrail tube 21 or sleeve 22 of the handrail unit 2 is fixedly provided. The exposed end of the limiting rod 6 is located on the movement path of the limiting block 23. After the handrail unit 2 is unfolded to the set position, the limiting block 23 abuts against the limiting rod 6, and the limiting rod 6 supports and limits the handrail unit 2. The state of the handrail unit 2 unfolded to the set position can be referred to Figure 9 As shown.

[0041] Regarding the limiting of the instrument unit 3, in this embodiment, the support arm 32 of the instrument unit 3 includes a movable groove 322. The exposed end of the limiting rod 6 passes through the movable groove 322. After the instrument unit 3 is unfolded to the set position, one end wall of the movable groove 322 abuts against the limiting rod 6 to limit the instrument unit 3. When the instrument unit 3 is in the folded state, the corresponding segment of the limiting rod 6 is located at or near the other end wall of the movable groove 322. The state of the instrument unit 3 unfolded to the set position can be referred to Figure 9 As shown.

[0042] To reduce rotational noise and wear of the handrail unit 2 and instrument unit 3, in this embodiment, several gaskets 7 are also installed on the rotating shaft 5. The gaskets 7 are arranged between two adjacent components, such as between the nut 53 and the inner wall of the sleeve 22, between the outer wall of the sleeve 22 and the upper wall of the column unit 1, between the upper wall of the column unit 1 and the support arm 32 of the instrument unit 3, and between the support arm 32 of the instrument unit 3 and the limiting flange 52 of the rotating shaft 5.

[0043] As one implementation method, the gasket 7 can be a plastic wear-resistant gasket.

[0044] In one embodiment, the upper end of the column unit 1 is fitted with a rubber sleeve 8. The assembly method can be a set, such as assembling it from top to bottom on the upper end of the column unit 1. The rubber sleeve 8 also has holes corresponding to the mounting holes 11 and holes for the limit rod 6 to pass through.

[0045] A treadmill includes an instrument and handrail rotating structure as described above. One column unit 1 is rotatably disposed on the left side of the treadmill body 4, and another column unit 1 is rotatably disposed on the right side of the treadmill body 4. Corresponding handrail units 2 are rotatably disposed on the outer sides of the two column units 1, while the left and right support arms 32 of the instrument unit 3 are rotatably disposed on the inner sides of the two column units 1, forming a structure as described above. Figure 9 The layout shown is as follows.

[0046] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended 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.
