Benefits of technology

This patent describes a new design for a selector pin that is used in a weight lifting machine. The selector pin can be easily engaged and disengaged from the machine, allowing for safe travel within the machine. The Sanstem has a knob or gripping surface to prevent accidental removal of the pin. Additionally, the patent also discusses the use of spring-loaded ball bearings and grooves in the pin to provide a better feel for the user. The patent also mentions that the new design eliminates the need for belts and pulleys to transfer energy for the movement of the weight stack.

Problems solved by technology

A selector pin is movably mounted, but not removable from the movable car traveling within the horizontal internal cavity when the selector pin is disengaged from the selector stem within the radial extending cavity.
A selector pin is movably mounted, but not removable from the movable car traveling within the segmented track when the selector pin is disengaged from the selector stem within the radial extending cavity.

Embodiment Construction

[0055]Set forth below is a description of what is currently believed to be the preferred embodiment or best examples of the invention claimed. Future and present alternatives and modifications to this preferred embodiment are contemplated. Any alternatives or modifications which make insubstantial changes in function, in purpose, in structure or in result are intended to be covered by the claims in this patent.

[0056]A typical weight lifting apparatus 10 as known in the prior art is shown by way of example in FIGS. 1-4. Generally, such an apparatus 10 includes a weight stack assembly 20, a movement assembly 40 for receiving work or force from a user, and a pulley system 50 to facilitate or translate the gravitational force from the weight stack assembly 20 so as to provide resistance to the movement assembly 40. The movement assembly 40 typically includes a movement arm 42 which is displaced by the user during exercise, and a pivot point 44 which permits rotation of the user's force ...

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.

Description

PRIORITY OF INVENTION [0001]The present invention incorporates by reference and claims priority to Provisional Application No. 61 / 629,443, Filed Nov. 18, 2011, and Provisional Application No. 61 / 631,734, Filed Jan. 10, 2012.FIELD OF THE INVENTION [0002]The present invention relates to a weightlifting system and selector pin component thereof. In particular, this invention relates to a selector pin assembly, track and / or weight plate for use with body building equipment, and more particularly to a selector pin which is not removable from a car which travels either along a track or within the weight plate bodies which can then be inserted through the car and the track into a throughbore or selection point in a weight plate or through the car directly into the throughbore in order to safely, reliably and easily engage a connection union with a vertically or horizontally running selector stem.BACKGROUND OF THE INVENTION AND PRIOR ART [0003]A traditional weight stack for use on what is k...
