Abstract:
1. An electric rim strike surface mountable on a door frame, comprising: a pivotally-rotatable keeper, including: a pivotally-rotatable locking bar including two extension arms, each extension arm having a rear inclined blocking face to engage a respective front blocking face of the keeper; a thrust mechanism; and an anchor including a spacer, wherein, when the thrust mechanism is de-energized, the anchor engages the locking bar to prevent the locking bar from rotating, and the rear blocking faces engage the respective front blocking faces to prevent the keeper from rotating, and when the thrust mechanism is energized, the anchor is driven towards the thrust mechanism, the spacer maintains an air gap between the anchor and the thrust mechanism, the anchor disengages from the locking bar to allow the locking bar to rotate, and the rear blocking faces disengage from the respective front blocking faces to allow the keeper to rotate.
