Abstract
A chest press exercise apparatus is provided. The chest press apparatus includes a selectable eight mechanism and a support member which pivotably supports a pair of four-bar linkage mechanisms. The four-bar linkage mechanisms are pivotably mounted at their rearward ends about axes which are disposed at an angle relative to a horizontal plane, i.e. are tilted relative to vertical, such that a pair of elongated bars of the four-bar linkage mechanisms travel in planes which are tilted relative to vertical. The tilted planes through which the four-bar linkage mechanisms travel enable the handles to travel along a slightly curvilinear downwardly diverging path which simulates as natural a human musculoskeletal upward pushing motion as possible.
Claims26
A chest press exercise apparatus, comprising:
- a base member;
- a support member extending from the base member;
- a pair of four-bar linkage mechanisms supported by the support member, the pair of four-bar linkage mechanisms each including a primary lever arm pivotable about a primary axis, a follower lever arm pivotable about a secondary axis, and a handle lever arm operatively associated with both the primary and follower arms, the primary axes being disposed at an angle with respect to each other such that proximal ends of each axis converge downwardly toward the base member;
- and
- a weight mechanism operatively associated with the pair of four-bar linkage mechanisms.
The chest press exercise apparatus of claim 19, wherein the primary axes are spaced apart from the secondary axes by a distance of about 3.75 inches.
A chest press exercise apparatus, comprising:
- a base member;
- a support member extending from the base member;
- a pair of four-bar linkage mechanisms supported by the support member, the pair of four-bar linkage mechanisms each including a first lever arm pivotable about a first axis, a second lever arm pivotable about a second axis and a handle lever arm pivotally attached to both the first and second lever arms, proximal ends of the primary and secondary axes converge downwardly toward the base member the first and second lever arms of each four-bar linkage mechanism traveling in a common plane upon pivoting, the common planes of the pair of four-bar linkage mechanisms being different planes from each other;
- and
- a weight mechanism operatively associated with the pair of four-bar linkage mechanisms.
