ABSTRACT:

FIELD OF THE INVENTION
The present invention relates generally to an exercise machine, and more particularly to an exercise machine for building muscles.
BACKGROUND OF THE INVENTION
As shown in
FIG. 1
, a muscle-building exercise device of the prior art comprises a frame
1
which is provided with a slide member
2
connected with a plurality of elastic members
3
having a damping effect. The slide member
2
can be kept at a first position which is located at the front section of the frame
1
. The slide member
2
is further connected with a pull cord
4
which can be pulled to locate the slide member
2
at the second position opposite to the first position. The exercise effect is brought about by pulling repeatedly the pull cord
4
so as to cause the slide member
2
to slide back and forth on the frame
1
. The magnitude of the exercise effect can be adjusted by increasing or decreasing the number of the elastic members
3
.
SUMMARY OF THE INVENTION
It is the primary objective of the present invention to provide an exercise machine comprising a frame which is provided thereon with a sliding seat pad, a slide member, and a pull cord. The sliding seat pad can be connected with the slide member and actuated by the pull cord to move back and forth on the frame. When the sliding seat pad is connected with the slide member, the exercise machine is provided with a damping effect.
It is another objective of the present invention to provide an exercise machine comprising a frame which is slantingly disposed to enable the sliding seat pad to slide on the frame by the pulling force at such time when the sliding seat pad is not connected with the slide member.
In keeping with the principle of the present invention, the foregoing objectives of the present invention are attained by an exercise machine comprising a frame of a predetermined length and having a load mechanism to provide a slide member with a load. The slide member is capable of sliding back and forth between a first position and a second position on the frame. The frame is further provided with a pull cord. The sliding seat pad is mounted on the frame and provided in the underside thereof with a slide wheel. When the pull cord is pulled, the sliding seat pad is actuated to slide back and forth between the first position and the second position on the frame. The sliding seat pad is provided with a link portion. The slide member is provided with a traction portion capable of being coupled with the link portion of the sliding seat pad.
