Abstract: An anti-vandal door lock apparatus in which a cylinder lock such as a mortise lock cylinder is employed for unlatching a cylindrical lock assembly. In a preferred embodiment, the mortise lock cylinder is mounted to the outside of a door trim such as a pull plate, with the cylindrical lock mounted to the inside of the trim, and the pull plate is mounted to the door, in such manner as to effect an anti-vandal door lock assembly. Preferred embodiments may include a hold-back feature, as well as a feature for facilitating secured removal of the mortise lock cylinder as for re-keying.

Abstract: A door stop having a retaining member having a shell defining a cavity, and a ledge extending outwardly from a lower portion of the shell, and an elastomeric bumper received in the shell cavity and having an exposed front surface, with the ratio of the length of the exposed bumper front surface to the thickness of the ledge is greater than about 8.0.

Abstract: A floor mounted doorstop employing an inner spacer having a first end and a second end, the first end disposed over the floor surface, an outer spacer having a first end and a second end, the first end disposed over the floor surface, and the outer spacer disposed around the inner spacer, a first rigid washer disposed over the second ends of said inner and outer spacers, a disk of a first height formed of a compressible material and having a first aperture formed therein disposed over the first rigid washer; a bushing of the first height disposed in the first aperture, a second rigid washer disposed over the disk, and fastening means for fastening the inner spacer, the outer spacer, the first rigid washer, the disk and the second rigid washer to the surface, the fastening means including means for compressing the outer spacer to a selected compression.

Abstract: A multi-point door lock system comprising an active lock and an inactive lock for use on single or double doors is self-teaching, provides one hand control of shoot bolts, and provides audible and tactile feedback associated with shoot bolt extension and retraction.

Abstract: A curved panic guard for use with external vertical rod exit devices has no sharp, angled or flat projecting surfaces to interfere with the passage of a wheelchair.

Abstract: A flush bolt including override protection is disclosed for flush mounting on the inactive one of a pair of swinging doors. In one embodiment of the invention, an automatic flush bolt comprising a trigger member senses whether the active door is closed. If closed, the flush bolt assumes an engaged position securing a bolt into a securing surface. If open, the flush bolt assumes its disengaged position with the bolt retracted into the mechanism. In a second embodiment of the invention, a semi-automatic flush bolt is provided with a slotted member and a spring to bias the bolt toward the engaged position. When the door containing the mechanism is closed, the bolt may temporarily and automatically override the securing surface and engage the securing surface without damage to the mechanism, the door, or the door frame. Opening the door requires manual intervention through activation of a control member.

Abstract: A door coordinator for controlling the closing sequence of a pair of double doors having a common line of closure. The coordinator has a biased trigger which pivots and a door stop which translates toward the rear of the coordinator upon triggering. Override is provided by an override block (preferably pivotally mounted) biased into a first position which moves to a second position upon application of more than threshold override force. With the override block in the second position, the door stop is free to move in translation to the rear of the coordinator and permit closure of the door even if the trigger is not depressed. Threshold override force is adjusted by a screw which adjusts the angular position of a base plate in contact with biasing springs which bias the override block.
