Abstract
Abstract A pivot or guide assembly for folding doors comprising a sleeve secured in its door-edge opening by driving it thereinto innerend-first. The sleeve is hexagonal to receive a hexagonal portion of a pivot or guide pin to prevent rotation of the pin while permitting vertical adjustment of the position thereof. Springs bias certain of the pins in such a way that the corresponding sleeves can be driven through the pins without damaging the springs. In one form, an annular retainer secures a rotatable nut to the outer end of the sleeve and the pin threadedly engages the nut so that rotation of the nut displaces the pin longitudinally of the sleeve without rotation of the pin. The sleeve is a split sleeve and the annular retainer limits spreading of the segments thereof. The disclosure also includes a folding-door bottom pivot assembly which includes a pivot bracket and a pivot socket adjustable relative thereto to adjust the horizontal position of the pivot axis of the door.
