Exercise machine having a sliding seat selectively coupled to a sliding damping member

An exercise machine comprises a frame on which a load mechanism and a sliding seat pad are mounted. The load mechanism is formed of a damping member and a slide member fastened with the damping member. The sliding seat pad has a link portion. The slide member is provided with a traction portion capable of coupling and uncoupling with the link portion of the sliding seat pad. The frame is further provided with a pull cord capable of pulling the sliding seat pad to displace at the time when the pull cord is pulled.

What is claimed is:

1. An exercise machine comprising a frame provided with a load mechanism which is formed of at least one damping member and a slide member whereby said slide member is mountedon said frame to slide back and forth between a first position and a second position on said frame, said frame further provided with a pull cord; wherein said frame is further provided with a sliding seat pad which is provided in the underside thereofwith a slide wheel connected with said pull cord whereby said pull cord is pulled to actuate said sliding seat pad to slide between said first position and said second position, said sliding seat pad further provided with a link portion; and whereinsaid slide member is provided with a traction portion to couple and uncouple with said link portion of said sliding seat pad, wherein said slide member and said sliding seat may slide independently of each other on said frame when said traction portionand link portion are uncoupled, and wherein said slide member and said sliding seat may slide together on said frame when said traction portion and link portion are coupled.

2. The exercise machine as defined in claim 1, wherein said frame is of a hollow rectangular construction and is provided in an outer wall of two sides thereof with a slide slot; and wherein said sliding seat pad is formed of a body and, aslide seat of an inverted U-shaped body and mounted on said frame, said slide seat provided in an inner wall of two sides thereof with at least one wheel whereby said wheel is slidably received in said slide slot to guide said sliding seat pad to slidesecurely on said frame.

3. The exercise machine as defined in claim 1, wherein said frame is of a hollow rectangular construction and is provided in an inner wall of two sides thereof with a guide slot; and wherein said slide member is of a rectangular constructionand is received in said frame, said slide member provided in an underside thereof with two guide wheels which are slidably received in said guide slots of said frame.

4. The exercise machine as defined in claim 1, wherein said frame is of a hollow rectangular construction and is provided in an upper surface thereof with a position confining slot of a length and extending along the direction of a longitudinalaxis of said frame; wherein said sliding seat pad is formed of a body and a slide seat having said link portion and a semicircular hole in which a locating pin is received such that said locating pin is also received in said position confining slot ofsaid frame, and that said locating pin is fitted into a spring which is located on a midsection of said locating pin by a nut in such a manner that said spring is located between an underside of said slide seat and said nut, said locating pin provided inan upper section thereof with a columnar section; and wherein said traction portion of said slide member is provided with a hole for receiving said locating pin so as to enable said slide member to actuate said sliding seat pad to displace.

5. The exercise machine as defined in claim 1, wherein said frame is provided in an underside thereof with a front support and a rear support greater in height than said front support.

6. The exercise machine as defined in claim 2, wherein said slide slot of said frame is provided in a front end thereof with a press member for locating said sliding seat pad at said first position.

7. The exercise machine as defined in claim 1, wherein said damping member is fastened at one end thereof with a rear section of said frame such that other end of said damping member is fastened with said slide member.
