Adjustable height door pivot

摘要

This pivot assembly for a swinging or folding door can be readily adjusted for door height or position of the door pivot axis relative to the door jamb. An L-shaped bracket is connected into the corner between the floor and door jamb. The bracket has a number of discontinuities parallel to the floor to prevent translation. A pivot is mounted on the lower corner of the door, preferably by a plastic sleeve. The sleeve is threaded on the inside and a threaded pin is mounted therein. The lower end of the pin has means directly engaging the jamb bracket to prevent rotation and translation of the pin. To adjust the door in most embodiments it is lifted so that the head of the pin is out of engagement with the teeth in the slot. The pin is rotated by hand to move it up or down in the threaded sleeve. The pivot axis of the pin is adjusted by moving the pin to a desired position on the bracket. In other embodiments a sliding portion on the pin is moved out of engagement with the bracket to adjust door height and distance of the pivot axis from the jamb.
