Release mechanism for locking pivotable leg

摘要

A release mechanism for a locking, pivotable leg for an assembly to allow an individual to use his foot to disengage the locking element which locks the pivotable leg into its operative position in which a plurality of such legs engage a supporting surface. The release mechanism includes a release pin having an enlarged head and transmission means to transmit movement of the release pin to the locking element moving it from its operative locking position. Where the locking element is of a type including a locking pin which is biased into a locking pin hole in a base bracket by biasing means such as a leaf spring, the transmission means of the present invention includes a release pin spring shoulder, a locking pin spring groove and a pin slot in the leaf spring disposed to engage these two components. Movement of the release pin causes the release pin spring shoulder to deflect the leaf spring which deflection is transmitted into movement of the locking pin in turn disengaging the locking pin from the locking pin hole in the base bracket, allowing the leg to pivot freely.
