Abstract
A door-stop for handicapped people and particularly people in wheel chairs which permits the person to push a self-closing door open and lock it in an open position before passing through the doorway. The door-stop is comprised of a pivoted cross bar mounted at a convenient height traverse to the door connected by means of a lever to a door-stop at the corner of the door. The door can thus be pushed open and the cross bar moved downward to lock the door-stop. After the person passes through the door, he can simply lift the cross bar to release the door-stop allowing the door to close.
Claims8
A self closing door in combination with a door stop mechanism, said door stop mechanism comprising:
- an elongate bar pivotally mounted cross-wise of said door about a pivot at a height to be easily reachable from a sitting or standing position;
- door-stop means pivotally mounted adjacent the lower edge of said door constructed and arranged to hold said door in an open position;
- linkage means linking said bar to said door-stop means;
- said linkage means being pivoted to said bar about a pivot axis parallel to said bar pivot axis;
- said linkage means being constructed and arranged so that a downward force applied to said bar moves said linkage means pivot axis from an over-centered position above said bar pivot axis to a lowered non over-centered position to simultaneously pivot said door-stop from a raised position to a down position to hold said door open and an upward force on said bar moves said linkage means pivot axis from said non over-centered position to said over-centered position above said bar pivot axis to simultaneously pivot said door-stop means from said down position to said raised position;
- said over-centered position of said linkage means pivot axis locking said bar and said door-stop in a raised position to allow said door to return to a closed position;
- whereby said door may be easily held open for passage and closed after passage therethrough.
