Abstract
An exercise machine for exercising the muscles of the upper body, in which a pushing or pulling movement can be performed in a direction approximately between horizontal and vertical towards or away from the shoulder joint of the user, with the user seated in the same position.
Claims22
A machine for exercising, the machine comprising:
- a stand having a seat for a user;
- a curved member connected to the stand and having a curved length curving on a radius that is centered at or near a shoulder point generally above said seat so that the shoulder point is near a shoulder of a seated user;
- an elongated, rigid grasp arm having an inner end and an outer end, a handle at or near the outer end, and a grasp arm length between said inner end and the handle, the inner end being at or near the curved member and pivotally connectable to the curved member at various connection locations along the curved length, so that the grasp arm pivots relative to the curved member when the handle is pushed or pulled by the user in an exercise movement;
- a resistance system operatively connected to the grasp arm to resist the pivoting of the grasp arm relative to the curved member;
- wherein the handle is constrained by said grasp arm to move, during the pivoting of the grasp arm and throughout the entire exercise movement, along a handle path that is a constant radial distance from the connection location, said constant radial distance being equal to said grasp arm length, and said handle path being between a retracted-position that is at or near said shoulder-point and a respective outreached-position distanced from the shoulder-point.

A machine for exercising, the machine comprising:
- a stand having a seat for a user;
- an attachment system connected to the stand and having a plurality of attachment points arranged along a curve on a radius that is centered at or near a shoulder point generally above said seat so that the shoulder point is near a shoulder of a seated user;
- an elongated rigid grasp arm having an inner end and an outer end, a handle at or near the outer end, and a grasp arm length between said inner end and the handle, the inner end being at or near the attachment system and pivotally connectable to the attachment system at any of said plurality of attachment points, so that the grasp arm pivots relative to the attachment system when the handle is pushed or pulled by the user in an exercise movement;
- a resistance system operatively connected to the grasp arm to resist the pivoting of the grasp arm relative to the attachment system;
- wherein the handle is constrained by said grasp arm to move, during the pivoting of the grasp arm and throughout the entire exercise movement, along a handle path that is a constant radial distance from the attachment point, said constant radial distance being equal to said grasp arm length, and said handle path being between a retracted-position that is at or near said shoulder-point and a respective outreached-position distanced from the shoulder-point.

A machine for exercising, the machine comprising:
- a stand having a seat for a user;
- a curved member connected to the stand and having a curved length curving on a radius that is centered at or near a shoulder point generally above said seat so that the shoulder point is near a shoulder of a seated user;
- a grasp arm pivotally connectable to the curved member in a number of positions along the curved length, and the grasp arm having a handle at an outer end, for being pushed or pulled by the user, so that the grasp arm pivots relative to the curved member;
- a resistance system operatively connected to the grasp arm to resist the pivoting of the grasp arm relative to the curved member;
- wherein the handle is constrained by said grasp arm to move, during the pivoting of the grasp arm, along a handle path between a retracted-position that is at or near said shoulder-point and a respective outreached-position distanced from the shoulder-point;
- wherein said resistance system resists pivoting of said pivoting of the grasp arm when the handle is moved along said handle path from the outreached-position to the retracted-position, so that pulling movements are resisted to provide exercise to the user;
- wherein said resistance system comprises a resistance arm operatively connected to the grasp arm and extending away from the curved arm in an opposite direction from the seat, said resistance arm having at or near an outer end a weight so that gravity pulls said resistance arm downward to provide resistance to the grasp arm and handle being pulled downward, and wherein the resistance arm is rigidly connectable to the grasp arm at different angles to the grasp arm.
