Abstract: An electric door strike assembly includes a housing and at least one keeper arm. The housing has an opening for admission and retraction of a door latch. The at least one keeper arm has a latch portion and is mounted on the housing. The at least one keeper arm is movable between a closed position, where the opening is occluded by the latch portion, and an open position, where the door latch may be released from the opening. The latch portion may include a bifurcated member having inside and outside legs arranged in spaced parallel relation so as to define a gap therebetween. The gap is configured to receive a latch plate of an interlocking latch mechanism when the at least one keeper arm is in the closed position.

Abstract: A strike plate mounting bolt assembly for resiliently mounting a strike plate to a door. The strike plate mounting bolt assembly includes a bolt and a post wherein the bolt is securably engageable with the post. The bolt is inserted through a bore in the door and the post is inserted through a bore in the strike plate. A resilient member such as at least one Belleville washer is disposed between a head of the post and a cavity in the strike plate wherein the at least one Belleville washer is compressed between the post head and cavity upon securing the bolt and post together to provide a resilient mount between the door and strike plate. The at least one Belleville washer may be a number of Belleville washers selectable stacked to form a pack of Belleville washers. By varying the number and orientation of the Belleville washers, the force/deflection characteristics of the pack may be tuned to accommodate the needs of a variety of electromagnetic lock design features.
