Resistance Selector for Exercise Apparatus

An exercise apparatus, comprising:

• a frame;
• at least one guide member coupled with a portion of the frame;
• a weight stack including a plurality of weight plates associated with the at least one guide member;
• a lifting mechanism, the lifting mechanism having a first end attached to a pull handle and a second end being attached to an weight attachment mechanism;
• and
• a resistance selector having a pin coupled to the weight attachment mechanism and configured to be displaced between at least a first position and a second position relative to the weight attachment mechanism,
• wherein when the pin is in the first position the weight attachment mechanism is interlocked with at least one plate of the weight stack and when the pin is in the second position the weight attachment mechanism is freed from the weight plates and wherein an engagement structure connected to the pin is configured to be rotated within the opening of the at least one plate to interlock with the at least one plate.

• and
• a resistance selector having a pin coupled to the weight attachment mechanism and configured to be displaced between at least a first position and a second position relative to the weight attachment mechanism;
• the pin being rigidly secured to at least a portion of a rail;
• wherein when the pin and the rail move collectively into the first position the weight attachment mechanism is interlocked with at least one plate of the weight stack and when the pin and the rail collectively move into the second position the weight attachment mechanism is freed from the weight plates.
