Claims
- 1. A strike comprising:
- a housing with a plurality of walls;
- a keeper mounted on said housing for movement from a first position to a second position for respectively engaging a latch and moving away from the latch, said keeper having at least one lug extending therefrom toward a wall of said housing and movable along a predetermined path in a plane with movement of said keeper;
- a locking member slidable mounted on said housing intermediate said keeper and said wall of said housing and movable rectilinearly in the direction transverse to said plane and said predetermined path of movement of said lug, said locking member having at least one arm thereon extending toward said lug, transversely of and away from aid wall and transversely to the direction of sliding movement of said locking member, said arm being engageable with said lug in one position of said locking member relative to said keeper for preventing movement of said keeper and said arm being out of the path of movement of said lug when said locking member is in another position relative to said keeper;
- biassing means acting between said locking member and said housing and urging said locking member into one of the relative positions thereof; and
- locking member actuating means for moving said locking member from the last-mentioned said one relative said position thereof into the other relative position thereof.
- 2. A strike as set forth in claim 1 wherein said locking member actuating means is an electrically energizable coil and said locking member has a magnetic portion adjacent but spaced from said coil which is urged toward said coil by the magnetic field thereof when said coil is electrically energized.
- 3. A strike as set forth in claim 2 wherein said biassing means is intermediate said magnetic portion and said coil.
- 4. A strike as set forth in claim 3 wherein said locking member actuating means comprises a pair of wire coils in laterally spaced relation and a pair of magnetic cores, one core within one of said coils and the other core within the other of said coils and wherein said magnetic portion of said locking member extends from adjacent one of said cores to adjacent the other of said cores.
- 5. A strike as set forth in claim 1 wherein said housing has a wall extending in a plane substantially perpendicular to the length of said arm and said locking member is in contact with said wall of said housing.
- 6. A strike comprising:
- a housing;
- a keeper pivotally mounted on said housing for pivotal movement around an axis from a first position to a second position for respectively engaging a latch and moving away from the latch, said keeper having two lugs extending therefrom transversely to said axis and spaced from each other in the direction of said axis by a predetermined distance;
- a locking member mounted on said housing for rectilinear sliding movement in the direction substantially parallel to said axis, said locking member having two arms thereon, each arm extending, respectively, toward one of said lugs and being engageable with the respective one of said lugs in one position of said locking member relative to said keeper for preventing movement of said keeper and being out of the paths of movement of said lugs when said locking member is in another position relative to said keeper, and one of said arms being spaced from the other of said arms by said predetermined distance;
- biassing means acting between said locking member and said housing and urging said locking member into one of the relative positions thereof; and
- locking member actuating means for moving said locking member from the last-mentioned said one relative said position thereof into the other relative position thereof.
- 7. A strike comprising:
- a housing, said housing having a front wall, a rear wall spaced from said front wall and a top wall extending from said front wall to said rear wall;
- a keeper pivotally mounted at said front wall for pivotal movement around an axis substantially parallel to said rear wall for movement from a first position to a second position for respectively engaging a latch and moving away from the latch, said keeper having two lugs thereon extending therefrom toward said rear wall but terminating in spaced relation to said rear wall, said lugs being spaced from each other in the direction of said axis by a predetermined distance;
- a locking member mounted in said housing for rectilinear sliding movement substantially parallel to said axis, said locking member being mounted intermediate said front wall and said rear wall and slidably abutting said rear wall, said locking member having two arms spaced from each other by said predetermine distance and extending, respectively, toward one of said lugs, said locking member being slidable between one position and another position, said arms being engageable with said lugs in one position of said locking member to prevent pivoting of said keeper and being out of the paths of movement of said lugs with pivoting of said keeper in the other position of said locking member to permit pivoting of said keeper;
- biassing means acting between said locking member and said housing for urging said locking member into a position fixed in relation to said top wall; and
- locking member actuating means mounted at the side of said locking member opposite from said top wall for pulling said locking member from said position thereof which is fixed in relation to aid top wall toward said locking member actuating means upon energization thereof.
- 8. A strike comprising:
- a housing with a plurality of walls;
- a keeper mounted on said housing for movement from a first position to a second position for respectively engaging a latch and moving away from the latch, said keeper having at least one lug extending therefrom toward a wall of aid housing and movable along a predetermined path in a plane with movement of said keeper;
- a locking member slidably mounted on said housing intermediate said keeper and said wall of said housing and movable rectilinearly in the direction transverse to said plane and said predetermined path of movement of said lug, said locking member having means thereon extending transversely to said predetermined path of movement of said lug, said means being engageable with said lug in one position of said locking member relative to said keeper for preventing movement of said keeper and said means being out of the path of movement of said lug when said locking member is in another position relative to said keeper to permit movement of said keeper;
- biassing means acting between said locking member and said housing and urging said locking member into one of the relative positions thereof; and
- locking member actuating means for moving said locking member from the last-mentioned said one relative said position thereof into the other relative position thereof.
- 9. A strike as set forth in claim 6 further comprising biassing means acting between said housing and said keeper for urging said keeper into said first position thereof.
- 10. A strike as set forth in claim 6 wherein said lugs and said arms have interengaging surfaces which lie in planes extending at an angle of less than about 15.degree. to said axis.
- 11. A strike as set forth in claim 7 wherein in said first position of said locking member said arms are engageable with said lugs.
- 12. A strike as set forth in claim 7 wherein in said first position of said locking member said arms are out of the paths of movement of said lugs when said keeper is pivoted.
- 13. A strike as set forth in claim 7 further comprising biassing means acting between said keeper and said housing and urging said keeper into said first position.
- 14. A strike as set forth in claim 7 wherein said locking member has a magnetic portion adjacent but spaced from said locking member actuating means, wherein said locking member actuating means comprises a pair of wire coils in laterally spaced relation and a pair of magnetic cores, one core within one of said coils and the other core within the other of said coils and wherein said magnetic portion of said locking member extends from adjacent one of said cores to adjacent the other of said cores.
- 15. A replacement locking member for the strike as set forth in claim 7, said replacement locking member having arms which are positioned on said replacement locking member so that in said one of said positions of said locking member, the last-mentioned said arms are out of the path of movement of said lugs when said keeper is pivoted to permit pivoting of said keeper and that in said other of said positions of said locking member said arms are engageable with said lugs to prevent pivoting of said keeper.
