Description

Roller treadmill

The present invention relates to a sports equipment, and more particularly to a drum type treadmill.

The general treadmill treadmill, such as the TW Bulletin No. 128972 patent, consists of a number of continuously arranged rollers. There is no running belt and running board. When the operator steps on it, the stepped roller will continue. Rotate and the speed of rotation accelerates.

There is also a tumbler treadmill (Taiwan Certificate No. M401455) which discloses that a plurality of rollers are mounted on a hollow frame, and the rollers can support a running belt to generate a cyclic rotation.

Although the aforementioned treadmill can achieve the intended operation purpose, the treadmill treadmill of the TW bulletin No. 128972 patent, only the stepped drum will rotate, and the rotational speeds of all adjacent drums are inconsistent. The fast rotating drum will make the operator's footsteps easy to slip, and the operator will not easily control the running speed. For example, in the case of the drum treadmill of the running belt No. M401455, when the operator's feet are cyclically stepped on the running belt, since each drum can independently freely roll relative to the frame, and because of the operation The squatting power of the two feet applied to different parts of the running belt may be inconsistent, so the resistance generated between the running belt and the corresponding drum will not be the same, and the operator's feet will have an uncoordinated condition. Moreover, because the rotation speed of each roller is different, the running belt may be pulled, which also affects the service life of the running belt, and there are still problems in that various strengths and difficulty in controlling the running speed are not achieved.

In addition, the running belt is self-propelled, has no damping structure, cannot be damped according to the user's needs, and cannot achieve the desired motion effect.

Accordingly, it is an object of the present invention to provide a treadmill that allows the operator to coordinate in steps.

Thus, the novel tumbler treadmill includes a frame unit and a drum unit. The frame unit has a front end portion and a rear end portion opposite to the front end portion. The roller unit includes a plurality of rollers disposed on the frame unit, and a plurality of idlers. The rollers are spaced apart between the front end portion and the rear end portion. Each of the rollers has a tilting wheel, and each of the two phases The idlers of the adjacent drums are each engaged with an idler, and each of the rollers can be rotated in the same direction and synchronously.

The utility model has the advantages that the idler wheel is engaged between the rolling wheels of each two adjacently disposed rollers, so that the rollers can be interlocked with each other and can generate the same direction and synchronous rotation, thereby operating In the drum unit, the rotation resistance and the rotation speed generated by the rollers are the same, so that the operator can achieve various running strength and speed control purposes according to the speed of the footsteps and the pedaling strength.

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.
