Abstract
A permanently affixed and travelling selector pin, car and weight plate selection mechanism for use with physical fitness equipment is disclosed including a segmented track and/or cut out cavern within the plate body for the car to travel within in either vertically or horizontally in order to select a different weight plate or cumulatively, more or less weight for an exercise. The selector pin and car mechanism features a selector pin which is not removable from the car and is inserted through the car which is contained by the track and or plate body shape and into a throughbore in the weight plate in order to engage with the selector stem.
Claims19
A weight lifting assembly, comprising:
- a weight stack comprising a plurality of weight plates in an aligned arrangement, each weight plate having first side that defines a lower catch, a second side that defines an upper catch, and a peripheral edge therebetween, the plurality of weight plates are aligned such that the lower catch and the upper catch of adjacent weight plates cooperatively align with each other;
- each weight plate of the plurality of weight plates defining:
- a u-shaped stem cavity disposed in an intermediate region of the plate, each stem cavity of the plurality of weight plates are aligned with each other, and
- a weight throughbore that extends axially between the peripheral edge and the stem cavity;
- a selector stem extends through the stem cavities of the plurality of weight plates to retain one or more of the plurality of weight plates for exercise;
- a movement arm pivotally coupled to the selector stem to displace one or more of the weight plates for exercise;
- and
- a selector pin having a knob and an elongated axial shaft extending therefrom, the shaft including a distal end;
- wherein the axial shaft of the selector pin is sized to extend through the weight throughbore of a selected weight plate of the plurality of weight plates to achieve union between the selector pin, the selected weight plate, and the selector stem, in an engaged position, thereby retaining one or more of the plurality of weight plates for exercise that are disposed on the first side of the selected weight plate.

- each weight plate of the plurality of weight plates defining a u-shaped stem cavity disposed in an intermediate region of the plate, each stem cavity of the plurality of weight plates are aligned with each other, the weight stack having:
- a plurality of engagement points corresponding to the plurality of weight plates, and
- a track defined by the weight stack for guiding between the plurality of engagement points;
- a selector stem that extends through the stem cavities of the plurality of weigh plates to retain one or more of the plurality of weight plates for exercise via the plurality of engagement points;
- and
- a selector pin having a knob and an elongated axial shaft extending therefrom, the shaft including a distal end, the pin includes a retaining portion disposed between the knob and the distal end on the shaft;
- wherein the axial shaft of the selector pin is sized to achieve union between the selector pin, the selected weight plate, and the selector stem, in an engaged position, thereby retaining one or more of the plurality of weight plates for exercise that are disposed on the first side of the selected weight plate, and, in a disengaged position, the retaining portion is captured within the track so as to preclude the removal of the selector pin, wherein further, in the disengaged position, the retaining portion of the selector pin is confined by the track such that the selector pin can travel along the track to enable selection of a weight plate of the plurality of weight plates.
