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.
Claims4
An electrically operable door strike, comprising:
- a housing with a plurality of walls, at least one of said walls comprising ribs extending outwardly from the wall toward an interior portion of the housing;
- a latch bolt keeper pivotally mounted on said housing for pivoting movement around a pivot axis from a first keeper position to a second keeper position for respectively engaging a latch and moving away from the latch, said keeper having at least one curved face spaced from said axis and substantially parallel to said axis;
- at least one locking member engaging arm extending from the face substantially perpendicular to said axis;
- a vertically disposed locking member slidably mounted on said housing intermediate said face and said ribs, said locking member being a substantially flat plate which is long relative to its width, which is rectilinearly vertically slidable in its length direction and in directions substantially parallel to said pivot axis and which has a thickness dimension which is transverse to its length and width, a pair of major surfaces in planes defining said thickness and at least one edge defined by said thickness and substantially perpendicular to said planes of said major surfaces, the edge having at least one notch extending substantially perpendicularly to the edge, which in a first locking member position and a third locking member position said edge is engageable and mates with said engaging arm of said keeper for preventing pivoting of said keeper and which, in a second locking member position said edge is out of engagement with and out of the path of movement of said engaging arm of said keeper and said engaging arm is permitted to move freely through said notch for permitting pivoting of said keeper;
- a spring acting between said keeper and said housing and urging said keeper into said first keeper position thereof;
- and
- a first solenoid for moving the locking member from the first locking member position to the second locking member position and a second solenoid for moving the locking member from the third locking member position to the second locking member position,
- wherein the first solenoid is actuated to move the locking member when the strike is installed in a door frame of a left hand operated door and the second solenoid is activated to move the locking member when the strike is installed in a door frame of a right hand operated door.

- wherein the first solenoid is actuated to move the locking member when the strike is installed in a door frame of a left hand operated door and the second solenoid is activated to move the locking member when the strike is installed in a door frame of a right hand operated door.
