A pivot assembly employs a pivot block to resist lateral forces and facilitate door alignment. The assembly includes a sleeve, pivot pin, pivot block and jamb bracket. The jamb bracket is connected to a corner between a jamb and a floor. The pivot block mounts on to the jamb bracket with anchors that engage serrations in a slot of the jamb bracket. The pivot block includes two halves resiliently connected at one end and separated by a gap, with a conical socket centered along the gap. A pivot pin is threaded into a sleeve mounted to the lower edge of a door to adjust height. A head on the lower end of the pin engages grooves in the pivot block socket. The pivot block halves separate to accommodate the pivot pin, and to cause the pivot block halves to be anchored in the jamb bracket. To properly align the door, the door is lifted to disengage the pivot pin from the pivot block. Vertical height is adjusted by rotating the pivot pin in the sleeve. Horizontal adjustments are made by pinching or squeezing the pivot block halves in order to slide it along the jamb bracket slot.

A pivot block for a pivot assembly for pivotally anchoring a vertically oriented door, said block comprising: two block halves; a resilient connection at one end of the halves connecting the halves, but normally holding them spaced from each other by a slight gap, each of said block halves having a mating recess forming a portion of a socket for receiving the head of a pivot pin depending from a lower edge of said door, said pin head having exterior splines; a plurality of grooves in each of the socket portions sized to receive the pivot pin splines; and an anchor depending from each block half and having a plurality of serrations extending laterally outward to mate with serrations in a slot in a mounting bracket to prevent movement of the block along the slot when the pin head, under the weight of the door, is pressed into said socket portions and urges said halves laterally outwardly.
