Abstract

The current invention relates to an exerciser, especially a crawling exerciser, comprising two hand slides each containing a wheel and two leg slides each containing a wheel, characterized in that, characterized in that it also contains components of a linear parallel track, wherein both the hand slides and the leg slides slide in the track and a damping structure is installed on the wheels or between the wheels and the track. The exerciser of the current invention is convenient, flexible, easy to control, and is easy to perform alternate movements of the hands and legs. It does not damage the floor, carpet or ground, and is very appropriate for indoor application.

Claims

1. A crawling exerciser, comprising two hand slides each containing a wheel and two leg slides each containing a wheel, wherein it also contains components of a linear parallel track, wherein both the hand slides and the leg slides slide in the track and a damping structure is installed on the wheels or between the wheels and the track.

2. The crawling exerciser according to claim 1, wherein the components of the track are soft rollable carpet track, and when the carpet is unfolded, the track is parallel and the cross section of the track is groove-shaped corresponding to the shape of the wheel.

3. The crawling exerciser according to claim 1, wherein the components of the track are soft rollable carpet track, and when the carpet is unfolded, the track is a straight, long fin height structure and is also designed to be parallel, wherein the outer part of the wheel is furnished with a curved groove in order to adapt to the fin-height-shaped track.

4. The crawling exerciser according to claim 1, wherein the components of the track are hard track components, wherein the wheels of the hand slides and the leg slides can make linear movements along the track, and the hand slides and the leg slides on the same side are connected with at least one elastic string.

5. The crawling exerciser according to claim 1, wherein the track components are designed to be foldable.

6. The crawling exerciser according to claim 1, wherein the track components are hard components, wherein the wheels of the hand slides and the leg slides can make linear movements along the track, and the wheels of the hand slides and the leg slides are further furnished with a volute spiral spring.

7. The crawling exerciser according to claim 6, wherein the track components are designed to be foldable.

8. The crawling exerciser according to claim 1, wherein the track components are hard components, wherein the wheels of the hand slides and the leg slides can make linear movements along the track, and the wheels of the hand slides and the leg slides on the same side are furnished with an elastic string.

9. The crawling exerciser according to claim 8, wherein the track components are designed to be foldable.

10.
