Integration of vertical adjustability in an electric strike
DCFirst Claim
1. An electric strike adapted to operate with a latch assembly that includes a latch bolt, a dead latch and a latch faceplate, wherein said electric strike is adapted to be disposed in a door frame and said latch assembly is adapted to be disposed in a door, wherein said latch faceplate includes a planar surface, said electric strike comprising:
- (a) a housing including a strike cavity, said housing having a longer longitudinal length than a housing width, wherein said strike cavity is configured for selectively receiving said latch bolt and said dead latch, and wherein said latch faceplate moves in a first direction relative to said housing when said latch bolt is selectively released from said strike cavity and said door is moved from a closed position away from said door frame in a door opening direction;
(b) a strike faceplate connected to said housing; and
(c) a ramp element connected to said housing, said ramp element is selectively positionable relative to said strike faceplate, said ramp element including a first ramp surface, a channel defined in said first ramp surface, and a longitudinal axis extending in a direction parallel to said first ramp surface and said longitudinal length of said housing along said ramp element,wherein said ramp element is selectively positionable relative to said strike faceplate along said longitudinal axis and in a plane parallel to said planar surface of said latch faceplate when said door is in said closed position and said strike cavity has received said dead latch thereby allowing for the selective adjustment of said channel so that said dead latch of said latch assembly is permitted to pass through said channel upon said movement of said latch faceplate in said first direction relative to said housing.

Abstract
An electric strike which provides vertical adjustability of the position of the strike relative to the latch bolt in the closure with modification to the doorframe on the dust box. A ramp element in the strike housing is adjustable relative to the strike and is securable at the time of installation to align the center of the latch bolt and strike. The ramp element has a channel to allow entry and exit of a latch bolt having a dead latch. A keeper engages the dead latch and maintains it in a retracted position when the closure is locked and is released when the electric latch solenoid is energized.

1. An electric strike adapted to operate with a latch assembly that includes a latch bolt, a dead latch and a latch faceplate, wherein said electric strike is adapted to be disposed in a door frame and said latch assembly is adapted to be disposed in a door, wherein said latch faceplate includes a planar surface, said electric strike comprising:
-
(a) a housing including a strike cavity, said housing having a longer longitudinal length than a housing width, wherein said strike cavity is configured for selectively receiving said latch bolt and said dead latch, and wherein said latch faceplate moves in a first direction relative to said housing when said latch bolt is selectively released from said strike cavity and said door is moved from a closed position away from said door frame in a door opening direction; (b) a strike faceplate connected to said housing; and (c) a ramp element connected to said housing, said ramp element is selectively positionable relative to said strike faceplate, said ramp element including a first ramp surface, a channel defined in said first ramp surface, and a longitudinal axis extending in a direction parallel to said first ramp surface and said longitudinal length of said housing along said ramp element, wherein said ramp element is selectively positionable relative to said strike faceplate along said longitudinal axis and in a plane parallel to said planar surface of said latch faceplate when said door is in said closed position and said strike cavity has received said dead latch thereby allowing for the selective adjustment of said channel so that said dead latch of said latch assembly is permitted to pass through said channel upon said movement of said latch faceplate in said first direction relative to said housing. - View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13)

14. A system comprising:
-
(a) a latch assembly disposed in a door, said latch assembly including a latch bolt, a dead latch and a latch faceplate, wherein said latch faceplate includes a planar surface; and (b) an electric strike operatively associated with said latch assembly, said electric strike being disposed in a door frame, said electric strike comprising a housing, a strike faceplate connected to said housing, and a ramp element, wherein said housing includes a strike cavity, said housing having a longer longitudinal length than a housing width, wherein said strike cavity is configured for selectively receiving said latch bolt and said dead latch, and wherein said latch faceplate moves in a first direction relative to said housing when said latch bolt is selectively released from said strike cavity and said door is moved from a closed position away from said door frame in a door opening direction, and wherein said ramp element is connected to said housing, said ramp element is selectively positionable relative to said strike faceplate, said ramp element including a first ramp surface, a channel defined in said first ramp surface, and a longitudinal axis extending in a direction parallel to said first ramp surface and said longitudinal length of said housing along said ramp element, wherein said ramp element is selectively positionable relative to said strike faceplate along said longitudinal axis and in a plane parallel to said planar surface of said latch faceplate when said door is in said closed position and said strike cavity has received said dead latch thereby allowing for the selective adjustment of said channel so that said dead latch of said latch assembly is permitted to pass through said channel upon said movement of said latch faceplate in said first direction relative to said housing. - View Dependent Claims (15)
