Abstract

The treadmill comprises a base frame adapted to rest on a surface which has left and right inner sides and left and right outer sides; a tread base having a frame including a front end, a rear end, and left and right outer surfaces; a linkage assembly having a first end connected to the front of the tread base and a second end connected to the base frame. The lateral width between the left and right outer sides of the base frame is substantially same with the lateral width between the left and right outer surfaces of the tread base; the linkage unit is approximately mounted in a space which is formed by the left and right inner surfaces of the base frame and the bottom of the tread base.

Claims

1. A treadmill comprising:

(a) a base frame adapted to rest on a surface, which having left and right inner sides and left and right outer sides defining a lateral width;

(b) a tread base having a frame and an endless belt coupled to said frame, the frame including a front portion connected to said base frame and a rear portion, the front portion having left and right outer sides defining a lateral width, wherein the lateral width of the tread base is approximately same as the lateral width of the base frame; and

(c) left and right support structures, each of said left and right support structures having a top end and a bottom end, said bottom ends respectively mounted on said left and right outer sides of the base frame.

2. The treadmill of claim 1, wherein the front of said tread base is positioned between the left support structure and the right support structure.

3. The treadmill of claim 1, wherein fronts of left and right outer side of the tread base are positioned over the left and right outer sides of the base frame.

4. The treadmill of claim 2, each of said left and right support structures having a post and an extending member, wherein each of the extending members extends from the bottom end of post and is mounted on the base frame.

5. The treadmill of claim 1, each of said left and right outer sides of the base frame further comprising an outward connecting portion, correspondingly, each of said bottom ends of said left and right support structures further comprising an inward connecting portion which is mounted with said outward connecting portion.

6. The treadmill of claim 4, said base frame further comprising upward connecting portions which are mounted nearby the outward connecting portions of said left and right outer sides of the base frame, correspondingly, each of the bottom ends of the left and right support structures further comprising a downward connecting portion which is mounted with said upward connecting portion.

7. The treadmill of claim 5, further comprising a plurality of screws which mount said bottom ends of said left and right support structures on said base frame.

8. The treadmill of claim 1, wherein a distance between said bottoms of said left and right support structures is longer than said lateral width of said base frame.
