Abstract
A slide bolt type of closure locking system is disclosed in various configurations in various orientations. A lever arm is used to operate the bolt slide. A detent arrangement normally keeps the lever arm in a nested rest position. The arm can be released from the detent to pivot the arm outward to operate the bolt slide. A pivot blocker is operable to prevent folding of the arm from its outward posture when needed to operate the bolt slide. Various lock case configurations are adapted to embedded or socket-mounting, or channel mounting, or surface mounting installations in swinging, sliding or folding closures.
Claims9
A slide lock comprising:
- an elongate case;
- a slide mounted to said case, said slide having a longitudinal axis and mounted to said case for sliding relative to said case and in the direction of said axis, between a first position and an second position, said slide having a recess;
- a lever having an arm and a base and mounted on said slide, said lever being operable between a first condition with said arm received in said recess in said slide, and a second condition with said arm projecting in a direction transverse to the axis of said slide;
- said case having first and second slide blocker detents at locations spaced along a line parallel to said axis;
- said lever base having a portion receivable in said first detent when said slide is in said first position with said lever in said first condition, and said portion being received in said second detent when said slide is in said second position and said lever is in said first condition, to inhibit said slide from sliding relative to said case when said lever is in said first condition;
- a lever lock mounted in said slide, said lever lock being engageable with said lever and operable, when actuated, to prevent said lever from returning from said second condition to said first condition;
- said lever lock is mounted in said slide and is slidable relative to said slide between a disabled condition and an enabled condition;
- and
- said lever lock is slidable, upon actuation, from said disabled condition to said enabled condition when said lever is in said second condition, to lock said lever in said second condition.
A locking system in a structure having a wall defining an exterior and an interior of the structure, the structure having an opening therein for passage between the said exterior and interior, and the structure having a partition mounted to the structure and movable relative to the wall to selectively open and close at least part of said opening, the structure having a stationary lock base at said opening and a lock base on said partition, the system comprising:
- an elongate case mounted on said one of said lock bases;
- a slide mounted to said case, said slide having a longitudinal axis and mounted to said case for sliding relative to said case and in the direction of said axis, between a first position and a second position, said slide having a recess;
- a lock bolt on said slide and engageable with the other of said lock bases when said partition is moved to a position closing at least part of said opening;
- a lever having an arm and having a hub and pivotally mounted on said slide, said lever being pivotally operable between a first condition with said arm received in said recess in said slide, and a second condition with said arm projecting in a direction transverse to the axis of said slide, to enable use of said arm to slide said lock bolt into engagement with the other of said lock bases to lock said partition in said position closing at least part of said opening;
- said partition has a front face, a back face and an astragal forming an edge;
- and
- said case is located in said astragal;
- said astragal has a groove therein;
- said case is retained in said groove;
- and
- said case is retained in said groove by friction fit in said groove.
