Description

Roller treadmill

The invention relates to a sports equipment, in particular 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 drum type treadmill of the present invention comprises 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 linkages disposed between the front end portion and the rear end portion, the rollers each having a tilting wheel, each of the two phases An interlocking member that can be interlocked with each other is connected between the tilting wheels of the adjacent drums, and each of the rollers can be rotated in the same direction and synchronously.

The utility model has the advantages that the connecting rods are connected 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.
