Exercise machine having rotatable weight selection index
First Claim
1. A weight exercise machine for use by a user, the machine comprising:
- an exercise member against which the user exerts an exercise force when using the machine to exercise;
a base frame;
a weight arm operatively associated with the exercise member and pivotally coupled to the base frame;
a plurality of weight plates pivotally coupled to the base frame to pivot about a pivot axis; and
an index including an axle that is rotated to selectively operably couple and selectively decouple the weight plates to the weight arm such that displacement of the exercise member results in the weight arm displacing relative to the base frame, any of the weight plates coupled to the weight arm to pivot about the pivot axis, and any of the weight plates decoupled from the weight arm to remain pivotally coupled to the base frame and not pivot about the pivot axis.

Abstract
The present invention is a weight exercise machine for use by a user. The machine comprises an exercise member, a plurality of weights, and an index. The user exerts an exercise force against the exercise member when using the machine to exercise. The index is rotated to operably couple the exercise member to at least one of the weight plates such that the displacement of the exercise member causes the at least one of the weight plates to displace. The plurality of weight plates includes a first weight plate type and a second weight plate type having configurations and masses that differ. The index allows selection of different combinations of weight plates for operable coupling to the exercise member.

9. A weight exercise machine comprising:
-
an exercise member against which a user exerts an exercise force; a base frame; a first weight pivotally coupled to the base frame to pivot about a pivot axis; a weight arm pivotally coupled to the base frame and operatively associated with the exercise member; a first axle rotatable to selectively operably couple and operably decouple the first weight to the weight arm; displacement of the exercise member causes the weight arm to displace relative to the base frame; and when the weight arm displaces relative to the base frame, the first weight pivots about the pivot axis when coupled to the weight arm and does not pivot about the pivot axis when decoupled from the weight arm. - View Dependent Claims (10, 11, 12, 13, 14)

15. A method of exercising with a weight exercise machine, the method comprising:
-
rotating an axle to selectively operably couple and selectively decouple a weight arm to a first weight plate combination, wherein the weight arm is operably coupled to an exercise member and the first weight plate combination is pivotally coupled to a base frame to pivot about a pivot axis; and exerting a first force against the exercise member to cause the weight arm and first weight plate combination when coupled to the weight arm to displace as a unit relative to the base frame with the first weight plate combination pivoting about the pivot axis and to cause the weight arm to displace relative to the base frame when the first weight plate combination is decoupled from the weight arm with the first weight plate combination remaining pivotally coupled to the base frame and not pivoting about the pivot axis, wherein the weight arm is pivotally coupled to the base frame. - View Dependent Claims (16)
