Abstract
A chest exerciser includes a hollow seat with top and bottom walls, and left and right side walls interconnecting the top and bottom walls. Each of the side walls has a horizontally extending slide groove which has front and rear groove ends proximate to front and rear ends of the hollow seat, respectively. Each of a pair of lever members includes an inner shaft which has a pivot end extending through the slide groove in a respective side wall and pivoted to the hollow seat about a vertical pivot axis, an outer tube sleeved on the inner shaft and having an abutment end abutting against an outer wall surface of the respective side wall, and a resistance unit for providing resistance to relative axial movement between the inner shaft and the outer tube.

A chest exerciser comprising:
- a hollow seat having front and rear ends, top and bottom walls extending between said front and rear ends, and curved left and right side walls interconnecting said top and bottom walls and extending between said front and rear ends, each of said side walls having a horizontally extending slide groove formed therethrough and extending therealong, said slide groove having a front groove end proximate to said front end of said hollow seat, and a rear groove end proximate to said rear end of said hollow seat, each of said side walls having an outer wall surface opposite to the other one of said side walls;
- and
- a pair of lever members, each of which includes an inner shaft which has a pivot end extending through said slide groove in a respective one of said side walls of said hollow seat and connected pivotally to said hollow seat for pivoting about a vertical pivot axis transverse to said top and bottom walls, an outer tube sleeved co-axially on said inner shaft and having an abutment end abutting against said outer wall surface of the respective one of said side walls of said hollow seat, and a resistance unit for providing resistance to relative axial movement between said inner shaft and said outer tube;
- said outer wall surface of each of said side walls of said hollow seat being defined by a curve, points on the curve increasing in distance relative to said pivot axis of a respective one of said lever members from said rear groove end to said front groove end;
- said outer tube of each of said lever members being operable for moving relative to said inner shaft in an axial direction away from said hollow seat against action of said resistance unit, said outer tube of each of said lever members being further operable for moving said inner shaft pivotally about said pivot axis to enable said inner shaft to slide along said slide groove in the respective one of said side walls from said rear groove end toward said front groove end, thereby enabling said outer wall surface of the respective one of said side walls to push said abutment end of said outer tube for moving said outer tube axially relative to said inner shaft against the action of said resistance unit.
