Abstract
A collapsible leg structure for one end of a bench, table, work surface, or the like, including a T-shaped brace rod having one end of its stem pivotally connected to the underside of the bench and its other end lockingly engaged with the depending end portion of the legs. A strut, pivotally connected with the stem of the brace rod, is slidably engaged with a track bracket secured to the undersurface of the bench to limit downward movement of the brace rod with respect to the bench. Links connecting the legs to the strut collapse the legs to a folded position under the bench when the brace rod is manually released from the legs and moved toward the underside of the bench.
Claims11
A collapsible bench or horizontal support having a top, comprising:
- leg means including at least one leg extending longitudinally of the underside of said top and pivotally connected at one end portion to one end portion of said underside for vertical pivoting movement of the leg other end portion about a horizontal axis toward and away from said underside;
- brace rod means including an elongated rod extending longitudinally of said underside and pivotally connected at one end portion to said underside in spaced relation with respect to the connected end of said leg for vertical pivoting movement of the rod other end portion about a horizontal axis toward and away from said underside,
- said rod other end portion having an aperture;
- link and bracket means interconnecting said leg means and said brace rod means with each other and with said underside for simultaneously pivoting said other end portions of said leg and said brace rod in opposing directions toward a downwardly converging juxtaposed position in response to movement of said rod other end portion away from said underside;
- and,
- locking means including an outstanding lock pin secured to said leg other end portion for entering the rod aperture and connecting said leg with said brace rod at their convergent position for forming a load bearing structure.

Collapsible folding leg and brace structure for a bench or the like having a bench top, comprising:
- a pair of bench legs having upper and lower end portions;
- bench leg bracket means pivotally connecting the upper end portions of said pair of bench legs to the underside of one end portion of said bench top on transversely aligned inclined axes for disposing the longitudinal axes of said pair of bench legs when erected in downward lateral and longitudinal diverging relation relative to said bench top,
- each leg of said pair of bench legs having a fixed collar surrounding its lower end portion;
- an upstanding lock pin supported by each said fixed collar;
- a brace rod projecting longitudinally of said bench between said pair of bench legs and having one end pivotally connected with said underside for vertical movement of its other end portion toward and away from said top one end portion,
- the brace rod other end portion having a cross bar provided with an aperture in its respective ends for receiving said lock pins in a bench leg erected locking action;
- and,
- link and track bracket means pivotally connecting an intermediate portion of said brace rod with the upper end portions of said pair of bench legs and with said underside for pivoting said pair of bench legs from an erected position to a parallel stored position against said underside and vice versa by vertical movement of said brace rod.

A collapsible bench or horizontal support having a top, comprising:
- leg means including at least one leg extending longitudinally of the underside of said top and pivotally connected at one end portion to one end portion of said underside for vertical pivoting movement of the leg other end portion about a horizontal axis toward and away from said underside,
- said leg having a lug-like extension on its said other end portion;
- brace rod means including an elongated rod extending longitudinally of said underside and pivotally connected at one end portion to said underside in spaced relation with respect to the connected end of said leg for vertical pivoting movement of the rod other end portion about a horizontal axis toward and away from said underside;
- link and bracket means interconnecting said leg means and said brace rod means with each other and with said underside for simultaneously pivoting said other end portions of said leg and said brace rod in opposing directions toward a downwardly converging juxtaposed position in response to movement of said rod other end portion away from said underside;
- and,
- locking means including a lock pin on said brace rod other end portion for engaging the lug-like extension and connecting said leg with said brace rod at their convergent position for forming a load bearing structure.
