Description

Treadmill treadmill and its tracks

technical field

The invention relates to a crawler belt, in particular to a running platform of a treadmill and its crawler belt.

Background technique

A treadmill that does not use electric power to drive the running belt as disclosed in the U.S. Patent No. 8864627 is mainly formed with a plurality of auxiliary running belts rotating on the frame surrounded by the running belt, so as to enhance the running belt. smoothness of rotation. However, since the running belt itself has used a large number of serial elements when it is connected in series, if the above-mentioned rollers pivotally arranged on the frame are added, there are many and complicated components.

Referring to Fig. 1 and Fig. 2, another example is a treadmill 1 disclosed in Taiwan Patent No. M404030, which mainly includes a support frame 11 pivotally mounted on the support frame 11 and adjacent to a front end of the support frame 11. Two pairs of turntables 12 with a rear end, and a crawler running belt 13 that is respectively sleeved on the same side before and after the two turntables 12. The support frame 11 includes two reinforcing ribs 111 formed on a top surface. Each crawler running belt 13 includes several bearing units 131, several movable parts 132 connecting the two end faces of two adjacent bearing units 131, and several rolling parts pivotally arranged between two adjacent movable parts 132. 133, and several threaded joints 134 that respectively pass through the rolling member 133, the movable member 132 and the bearing unit 131.

When the crawler running belt 13 is driven by an external force, the rolling member 133 can slide on the reinforcing rib 11 of the support frame 11, and through the meshing relationship with the turntable 12, the crawler running belt 13 rotates smoothly around the turntable 12 in the support frame 11. In this way, the rolling element 133 and the movable element 132 are combined in the carrying unit 131 to achieve the purpose of simplifying components.

Only, because the bearing unit 131 uses a plurality of components such as the rolling member 133, the movable member 132, the screw connecting member 134, etc., the purpose of connecting the bearing unit 31 in series is achieved. Complicated, a large gap d will be formed between two adjacent bearing units 131 due to the length of the movable part 132, which is not beautiful, and each bearing unit 131 is required to pass through the screw joint 134 The thickness t is increased, so that the thickness and weight of each carrying unit 131 cannot be reduced.

The crawler belt 3 rotates around the frame 2 and includes several running boards 31 and several bolt groups 32 connecting the running boards 31 in series. Each running board 31 straddles the side plate 21, and has an inner surface 311 facing the sliding surface 211 of the frame 2, two sliding areas 313 formed on the inner surface 311 and adjacent to the two end surfaces 312, And a plurality of connection portions 315 formed on the opposite side surfaces 314 and spaced apart from each other. The sliding areas 313 respectively slide on the sliding surfaces 211 of the side plates 21 . The connecting portions 315 of two adjacent running boards 31 are spaced apart from each other and misaligned. Each bolt set 32 has a bolt 321 penetrating through the connecting portion 315 of two adjacent running boards 31 .

The decorative seat 4 includes two side covers 41 separated by a distance and located outside the side plates 21 of the frame 2, a bottom plate 42 respectively connected to a bottom edge of the side covers 41 and carrying the frame 2, and connected to the frame 2 respectively. A top edge of the side cover 41 and two top covers 43 adjacent to the end surface 312 of the running board 31 of the crawler belt 3 .

6 and 7, when the crawler belt 3 is driven by an external force, it will slide on the sliding surface 211 of the frame 2 with the sliding area 313, and rotate around the frame 2 along the sliding surface 211, and During the turning process, the crawler belt 3 is bent according to the curvature of the sliding surface 211 by utilizing the pivoting action of the connecting portion 315 of two adjacent running boards 31 .

It should be noted that, in this embodiment, the crawler belt 3 is not driven by electric power. Therefore, the aforementioned external force for driving the crawler belt 3 comes from the pedaling force of the user when running on the crawler belt 3. limit.

Referring to Fig. 8 and Fig. 9, it is a second embodiment of the present invention, which is roughly the same as the first embodiment, except that:

Each bolt assembly 32 of the crawler belt 3 also has two rollers 322 pivotally arranged on two opposite ends of the bolt 321 and exposed outside the two end surfaces 312 of two adjacent running boards 31 .

In this way, when the crawler belt 3 is driven by an external force, the two rollers 322 exposed outside the two end faces 312 of the two adjacent running boards 31 will slide on the sliding surface 211 at the opposite position of the frame 2 and circle around The sliding surface 211 rotates.

Referring to Fig. 10 and Fig. 11, it is a third embodiment of the present invention, which is roughly the same as the second embodiment, except that:
