ABSTRACT:
The present invention relates to a portable security door stop for dependably holding a door in a closed position again any unauthorized entry which may be quickly and conveniently installed on the inside of the door. The invention provides a door handle engaging yoke which is virtually impossible to dislodge from the door; has a convertible floor engaging member having a plurality of cleats for use of carpet but which are also adaptable to provide a mounting system for an auxiliary resilient block or pad adapted for use on relatively hard floor surfaces; and including an audio-alarm unit closely associated with the yoke which is triggered by even the inward movement of the door against the stop. The stop further includes upper and lower telescoping sections with a lock pin selectively extendable through a pair of sets of aligned apertures in the sections to hold them in predetermined extended and retracted positions; and an elongated slot in the lower section slidably receiving a pin in the upper section engageable with the ends of the slot precisely to align said pairs of sets of apertures.
