Elliptical exercise machine
An exercise machine includes a pair of slide members having front ends connected to a crank unit for turning along with the crank unit and rear ends linearly slidable on a support. A pair of reciprocating members are mounted on the support for reciprocating forward and backward. A pair of foot support members each have a front pivotal end and a rear free end. The front pivotal end of each foot support member is connected pivotally to one of the slide members between the front and rear ends of the slide member. Each foot support member is connected to one of the reciprocating members rearwardly of the front pivotal end.
1. An exercise machine comprising:
a support;
a pulley mounted on said support;
a crank unit connected to said pulley for rotation along with said pulley;
a pair of slide members having front ends connected to said crank unit for turning along with said crank unit and rear ends linearly slidable on said support;
a pair of reciprocating members mounted movably on said support for reciprocating forward and backward;
a pair of foot support members each of which has a front pivotal end and a rear free end, said front pivotal end of each of said foot support members being connected pivotally to one of said slide members between said front and rear ends of said one of said slide members, each of said foot support members being connected to one of said reciprocating members rearwardly of said front pivotal end.
2. The exercise machine as claimed in claim 1 , wherein said support includes a base and an upstanding frame extending upward from a front end of said base, said pulley being mounted on said base adjacent said upstanding frame.
3. The exercise machine as claimed in claim 2 , further comprising a pair of handles mounted pivotally on said upstanding frame, and a pair of swinging arms mounted pivotally on said upstanding frame and connected respectively to said handles for swinging simultaneously with said handles, each of said swinging arms having a top end connected to a corresponding one of said handles and a bottom end connected to a front end of one of said reciprocating members.
4. The exercise machine as claimed in claim 1 , wherein each of said slide members includes a top side opposite to said base, and a pivot member mounted on said top side and connected pivotally to said front pivotal end of a corresponding one of said foot support members.
5. The exercise machine as claimed in claim 4 , wherein each of said reciprocating members has a fixing unit which is provided rearwardly of said front pivotal end of a corresponding one of said foot support members, each of said foot support members being connected immovably to one of said reciprocating members through said fixing unit.
6. The exercise machine as claimed in claim 5 , wherein said fixing unit includes two fasteners that are spaced apart longitudinally from each other.
