Abstract
An exercise device which includes a first and second lever pivotally attached to a frame and pivotally interconnected by a connecting rod. A first arm is pivotally connected to the frame and a second arm is pivotally connected to the ends of the first arm and the second lever opposite the ends connected to the frame. The second arm includes a seat for the user, whose body weight provides a resistance to rotation of the free end of the first lever. In one embodiment a slide assembly is engaged with the second lever to selectively vary the resistance to rotation of the first lever.
Claims20
An exercise device which comprises:
- a frame;
- a first lever having a first end and a second end with said first end being pivotally attached to said frame for rotation about a first axis relative thereto;
- a second lever having a first end and a second end with said first end being pivotally attached to said frame for rotation about a second axis relative thereto;
- a connecting rod having a first end and a second end with said first end being pivotally attached to said first lever about a third axis relative thereto, and said second end being pivotally attached to said second lever about a fourth axis relative thereto;
- a first arm having a first end and a second end with said first end being pivotally attached to said frame about a fifth axis relative thereto;
- and
- a second arm having a first end and a second end with said first end being pivotally attached to said second end of said second lever about a sixth axis relative thereto, and said second end being pivotally attached to said second end of said first arm about a seventh axis relative thereto;
- whereby rotation of said first lever causes an upward movement of said second arm relative to said frame.
A method of exercising muscles, the method comprising:
- positioning a user on a seat that is rotatively coupled to a frame by a first arm and a second lever;
- a first lever pivotally attached to said frame;
- and
- a connecting rod having a first end pivotally attached to said first lever and a second end pivotally attached to said second lever;
- whereby a force applied by the user against said first lever causes a rotation of said seat relative to said frame.
An exercise device which comprises:
- a first lever pivotally attached to a frame;
- a slide assembly engaged with a second lever for selectively positioning and affixing said slide assembly to said second lever at alternate positions, said second lever pivotally attached to said frame;
- a connecting rod interconnecting said first lever and said slide assembly about pivotal attachments;
- a first arm pivotally attached to said frame;
- and
- a seat pivotally attached to the distal ends of said second lever and said first arm;
- whereby the body weight of a user positioned on said seat establishes a resistance to rotation of said first lever.
