Abstract
A portable spring loaded selector pin device comprising of an automatic release mechanism for use in performing intense weight lifting exercises involving reduced weight lifting sequences on weight lifting machines having weight stacks comprising of a plurality of weight plates. One or more spring loaded selector pin devices may be deployed, allowing the selection of multiple weight reductions to be preset. The spring loaded selector pin device utilizes the friction created by the weight plates to remain engaged while the weight is lifted, and automatically releases immediately after the weight is set down, making the next preset weight ready to be lifted without any interruption in the exercise.
Claims10
A spring loaded weight stack selector pin device used to preset one or more weight amounts to be lifted in decreasing succession of heaviest to lightest weight on a weight training machine having a weight stack consisting of a plurality of weight plates, the spring loaded weight stack selector device comprising:
- a pin having a shaft with a shaft end configured to be inserted into a weight plate selector hole;
- a pin shaft end having an abrupt raised edge;
- a handle attached to the pin shaft;
- a spring loaded apparatus movably mounted to the pin;
- an adjustment mechanism configured to reveal more or less of the pin shaft allowing the pin to fit into weight plate selector pin holes of varying lengths;
- a safety pin consisting of a shaft configured to be removeably engaged in the adjustment mechanism, and having a holding arm connected to the safety pin shaft configured to be inserted into a weight plate selector pin hole of the weight plate positioned directly underneath the weight plate to be lifted;
- and
- a lanyard to attach to the safety pin using the lanyard hole incorporated in the safety pin shaft, and using said lanyard as an anchor for the safety pin in the case where the entire weight stack is to be used in the weight lift, resulting in no weight plates remaining underneath the lifted grouping of plates.
