Description

Treadmill running platform and its crawler

The present invention relates to a crawler belt, and more particularly to a treadmill running platform and its crawler.

A treadmill that does not use an electric power to drive a running belt, as disclosed in U.S. Patent No. 8,886,627, which is mainly formed on a frame surrounded by a running belt, and has a plurality of rollers that are rotated by a plurality of auxiliary running belts to enhance the running belt rotation. Smoothness of time. However, since the running belt itself is connected in series, a large number of serially connected components have been used. If the aforementioned roller is pivoted on the frame, there are many disadvantages in that the components are complicated and complicated.

Referring to FIG. 1 and FIG. 2, the treadmill 1 disclosed in the Taiwan Patent No. M404030 is taken as an example, and mainly includes a support frame 11 pivoted on the support frame 11 and adjacent to the front end of the support frame 11 and A pair of two pairs of turntables 12 at the back end, and a running running belt 13 of the front and rear two turntables 12 on the same side. The support frame 11 includes two reinforcing ribs 111 formed on one top surface. Each of the crawling running belts 13 includes a plurality of carrying units 131, and a plurality of movable members 132 connecting the two end faces of the adjacent two carrying units 131, and a plurality of rolling members pivotally disposed between the adjacent two movable members 132. 133, and a plurality of screw members 134 that respectively pivot the roller members 133, the movable members 132, and the load bearing units 131.

When the crawling running belt 13 is driven by an external force, the rolling elements 133 can be slid on the reinforcing ribs 11 of the support frame 11 and the meshing relationship with the turntables 12 can be used to make the running running belt 13 The turntable 12 is smoothly rotated in the support frame 11. Thereby, the rolling elements 133 and the movable members 132 are combined in the carrying units 131 to achieve the purpose of streamlining the components.

However, since the rolling elements 133 and the movable members 132 are disposed on the two end faces of the carrying units 131, the supporting frame 11 and the two end faces of the supporting units 131 are required to be accommodated and not interfered. The rolling elements 133 and the movable parts 132 are rotated, so that the support frame 11 and the two end faces of the carrying units 131 form a large gap d, which is not only less beautiful, but also each carrying unit. In order to be able to pivot the screw 134, the thickness t is increased, so that the thickness and weight of each of the carrier units 131 cannot be reduced.

Accordingly, it is an object of the present invention to provide a treadmill and track thereof that can reduce the gap and thickness, simplify construction, reduce weight, and enhance aesthetics.

Thus, the treadmill of the treadmill of the present invention comprises a frame, and a Tracks.

The frame includes at least two sliding surfaces spaced apart from one another.

The track rotates around the frame and includes a plurality of running boards, and two chains serially connected to the running boards, each running board having an inner surface facing the sliding surfaces, each chain having a separate running board a plurality of chain sets that are internally connected and pivotally connected to each other, and a plurality of rollers pivotally disposed on the chain sets and slid on the sliding surfaces of the frame.

The track of the running platform of the treadmill of the present invention, the running table comprising a frame comprising at least two sliding surfaces spaced apart from each other, the track comprising: a plurality of running boards, and two chains.

Each running board has an inner face facing the sliding surfaces.

The chain is connected to the running boards, and each chain has a plurality of chain sets connected to the inner faces of the respective running boards and pivoted to each other, and are respectively pivoted on the chain sets and slid in the frame A number of rollers on the sliding surfaces.

The utility model has the advantages that: by using the chain disposed on the inner surface of the running boards, not only the running boards can be connected in series, but also sliding on the sliding surfaces, so that the crawling belt can achieve the purpose of rotating around the frame, and can reach Simplify construction, reduce weight, and enhance aesthetics.

Before the present invention is described in detail, it should be noted that in the following description, similar elements are denoted by the same reference numerals.

Referring to Figures 3 and 4, a first embodiment of the treadmill of the treadmill of the present invention comprises a frame 2, a track 3, and a trim 4.

The frame 2 includes two side plates 21 spaced apart from each other, and connects the sides A plurality of posts 22 of the plate 21. Each side panel 21 has a sliding surface 211 formed on one circumference.

The crawler belt 3 rotates around the frame 2 and includes a plurality of running boards 31, and two chains 32 connected in series with the running boards 31. Each of the running boards 31 has an inner surface 311 facing the sliding surfaces 211 of the frame 2, and two fastening regions 313 formed on the inner surface 311 adjacent to the two end surfaces 312. Each of the chains 32 has a plurality of chain sets 321 pivotally connected to each other, and a plurality of rollers 322 pivotally mounted on the chain sets 321 and sliding on the sliding surfaces 211 of the frame 2. Each of the chain sets 321 has two links 3211 corresponding to each other and connected to the fastening area 313 of the inner surface 311 of the running board 31, and two adjacent links 3211 of the adjacent two chain sets 321 Two pivoting pieces 3212. The rollers 322 are respectively pivoted between the two links 3211 of each of the chain sets 321 .

The decorative cover 4 includes two side covers 41 spaced apart from each other and located outside the side plates 21 of the frame 2, a bottom plate 42 respectively connecting the bottom edges of the side covers 41 and carrying the frame 2, and respectively connecting the bottom plates 42 The top cover 41 has a top edge and two top covers 43 adjacent to the end surface 312 of the running plate 31 of the track 3.

Referring to FIG. 6 and FIG. 7, when the crawler belt 3 is driven by an external force, the chains 32 disposed on the inner surface 311 of the running board 31 are slid by the rollers 322 on the sliding surface 211 of the frame 2. And following the sliding surface 211 to rotate around the frame 2.

It should be noted that in the present embodiment, the crawler belt 3 is not driven by electric power, and therefore, the external force for driving the crawler belt 3 comes from the user in the crawler belt 3 The pedaling force when running is not limited to this.

Referring to FIG. 8 and FIG. 9 , a second embodiment of the present invention is substantially the same as the first embodiment, except that the frame 2 further includes a side plate 21 disposed adjacent to the side plates 21 and adjacent to the side plates 21 . The front end has two sprocket sets 23 at the rear end. And each of the side plates 21 has two sliding surfaces 211 formed on one inner surface and spaced apart by a distance between the upper and lower sides. Each sprocket set 23 has two sprockets 231, and an axle 232 that passes through the sprocket 231 and the side panels 21.

The chains 32 of the crawler belt 3 respectively engage the two sprockets 231 on the same side of the sprocket set 23 and mesh with the sprocket 231 at the opposite position.

Therefore, when the crawler belt 3 is driven by an external force, the chains 32 disposed on the inner surface 311 of the running board 31 are slid by the rollers 332 on the sliding surface 211 of the frame 2, and The meshing relationship drives the sprocket 231 to rotate.

Through the above description, the advantages of the foregoing embodiments can be summarized as follows: The present invention can utilize the chain 32 disposed on the inner surface 311 of the running board 31, serially connect the running boards 31, and slide on the sliding surfaces 211. Therefore, the crawler belt 3 is rotated around the frame 2, and it is important that the end surface 321 of the running board 31 and the side panel 211 of the frame 2 have no other components, thereby simplifying the structure and reducing the weight. Improve the purpose of aesthetics.

However, the above is only an embodiment of the present invention, when The scope of the present invention is defined by the scope of the invention, and the equivalent equivalents and modifications of the scope of the invention are still within the scope of the invention.
