Abstract: An electric strike having two independent keepers. The strike works with a lockset having both a deadbolt and a mortise lock bolt. A latch adapted to engage a deadbolt is provided with a solenoid to lock or unlock the latch. Another latch adapted to engage a mortise lock bolt is provided with a solenoid to lock or unlock the latch. Each latch is independently operable.

Abstract: An electrically or manually actuated locking device comprising a magnetic reed switch as a sensor to monitor whether or not the device is locked. The reed switch is mounted on a circuit board to make a sub-assembly and the sub-assembly is coated with a plastic or other synthetic material which is impermeable to water and/or oil and which provides a degree of mechanical protection from breakage. The coated sub-assembly is then mounted within a housing incorporating the locking device. A pivotable magnet carrier which pivots when the bolt of the locking device is engaged causes the reed switch to be actuated.

Abstract: A magnetically mounted template for identifying the optimum installation location for a door hardware device. The template has a working element that engages a cooperating door hardware device, for example, a working latch that engages a bolt. The template is particularly suitable for installing electrically operable door hardware devices, such as electric strikes, which require wiring as well as mechanical attachment to a door frame or door.

Abstract: A high strength electrically operable door strike having a simplified design and a gravity fed locking member. The strike comprises two solenoids operating in opposite directions wherein one solenoid is used when the strike is mounted for use with a left hand opening door and the other solenoid is used when the strike is mounted for use with a right hand opening door. The strike is simply turned upside down to accommodate a door having the opposite hand. The strike has a housing which is reinforced with ribs. The ribs also provide a reduced surface area sliding surface for the gravity fed locking member and thereby permit the locking member to slide up and down with less friction.

Abstract: A surface mounted electric strike which can be installed on a door jamb without cutting the door jamb. The strike employs a simplified locking mechanism whereby two latches are releasably engaged by a single yoke. An electrical solenoid actuates a cam which directly actuates the yoke. The strike can operate in a fail safe mode or a fail secure mode.

Abstract: An electronically-operable door strike employing a guard clip for deterring picking of the locking mechanism therein, a springless solenoid designed to avoid the undesirable build-up of residual magnetism and which incorporates air gaps for dissipating heat, thus prolonging the useful life of the solenoid, and a face plate for mounting the strike into a door jamb.
