Abstract
A magnetically anchored quick release pin is provided for quickly and accurately preventing movement between two objects and/or quickly changing the relative position between two objects. One such use is in a weight lifting machine providing for variable resistance, which can be adjusted manually during a workout routine. The weight lifting machine includes one or more guides and a stack of weights which are slidably mounted on the guides and movable along the guides from a rest position to an elevated position. The weight lifting machine also includes a selector member and a lift member. Each of the weights includes an opening to receive a selector pin. The openings are aligned to define a passage through the stack of weights to allow the selector pin to couple each of the weights in the stack to the selector member. The selector pin has a magnetic means affixed thereto to enable one to couple and decouple from respective weights of the stack of weights without having to release a locking mechanism on the selector pin. The lift member is adapted to permit a user of the weight lifting machine to, for example, pull and thereby raise the weights coupled to the selector member from their respective rest positions to their respective elevated positions.

8. A weight lifting machine comprising:
-
a stack of weights, each of said weights having an opening, said openings being aligned to define a passage through said stack of weights;
at least one guide, each of said weights being slidably mounted on said at least one guide and being movable along said guide from a rest position to an elevated position;
a selector member, said selector member having a downwardly depending member, said downwardly depending member having a passage therethrough, said selector member including a rod or pin having magnetic means, said rod or pin shaped for insertion through a weight in the stack of weights and into the passage of the downwardly depending member such that said magnetic means attaches to the exposed side of a respective weight in said stack of weights; and
a lift means coupled to said selector member, said lift means being adapted to permit a user of said weight lifting machine to raise said weights attached to said selector member from its respective rest position to its respective elevated position. - View Dependent Claims (9, 10, 11, 12)

14. A weight lifting machine comprising:
-
a frame;
a stack of weights, each of said weights having an opening therein or between adjacent weights, said openings being aligned to define a passage through said stack of weights;
a least one guide supported by said frame, said weights being slidably supported on said guide and being movable along said guide from a rest position to an elevated position;
a selector member extending through said passage, said selector member having a plurality of cavities formed therein and a selector pin having a magnetic means, which pin is insertable through the selector member and weight stack whereby said magnetic attraction of said selector pin affixes said pin to a respective weight in said stack of weights; and
a lift member supported by said frame, said lift member being coupled to said selector member and being adapted to permit a user of said weight lifting machine to raise said weights coupled to said selector member by said selector pin from said rest position to said elevated position. - View Dependent Claims (15, 16, 17, 18, 19)

20. A weight selector assembly in combination with a plurality of aligned weight plates, comprising:
-
a base member; and
a selector rod mounted on said base member, wherein said selector rod includes a shaft extending through the weight plates and having a longitudinal axis, and a weight plate engagement member, wherein said engagement member has a magnetized portion whereby it may be affixed to said shaft at discrete axial locations, and said engagement member being extendable through or under a weight plate.
