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.
Claims16
A weight selector assembly for selecting a desired weight level from at least two weight levels, the assembly comprising:
- a track defined along the at least two weight levels, guiding between a plurality of engagement points corresponding to the plurality of different weight levels, each of the plurality of engagement points aligned with a corresponding track segment;
- and
- a selector pin for selectively engaging with one of the plurality of weights via one of the plurality of engagement points, the selector pin having:
- an elongated axial shaft, and
- a retaining portion movably disposed on the shaft, the retaining portion slides axially along the shaft between an engaged position and a disengaged position, in which in the engaged position the selector pin mechanically couples one of the plurality of engagement points, and in the 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 of the plurality of weight levels.
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 first flange, a second side that defines a second flange, and a peripheral edge therebetween, the plurality of weight plates are aligned such that the first flange and the second flange 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 tray disposed below the weight stack to support the plurality of weight plates when at rest;
- 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.
