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.

1. 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; andsaid 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.2. The slide lock of claim 1 and further comprising:a first lever retainer detent located on said lever arm;a second lever retainer detent located on said lever lock;said lever retainer detents being cooperable when said lever lock is disabled, to retain said lever in said first condition.3. The slide lock of claim 2 and further comprising:a first lever lock retainer detent located on said lever lock;a second lever lock retainer detent located on said slide;said first and second lever lock retainer detents being co-operable when said lever lock is in said enabled condition to retain said lever lock in said enabled condition.4. The slide lock of claim 3 and further comprising:a third lever lock retainer detent located on said slide, said first lever lock retainer detent and said third lever lock retainer detent being co-operable when said lever lock is in said disabled condition, to retain said lever lock in said disabled condition.5. The slide lock of claim 3 and wherein:said lever lock has a cantilever arm with a proximal end and a distal end; andsaid first lever lock retainer detent is on said cantilever arm at a location remote from said proximal end.6. The slide lock of claim 5 and wherein:said third lever lock retainer detent has a portion in the path of said first lever lock retainer detent as said lever lock is slid from said disabled condition to said enabled condition, whereby said cantilever arm is resiliently deformed by said first lever lock retainer detent engaging said third lever lock retainer detent during passage of said lever lock from said disabled condition to said enabled condition.7. 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; andsaid case is located in said astragal;said astragal has a groove therein;said case is retained in said groove; andsaid case is retained in said groove by friction fit in said groove.8. The locking system of claim 7 and wherein:said partition has a top and a bottom;said astragal comprises a metal extrusion; andsaid case has guide pads engaging said groove in said astragal, at least one of said pads being interference fitted in said groove to retain said case in said groove.9. The locking system of claim 8 and wherein:said astragal extends between the top and bottom of said partition; andsaid case is located adjacent the bottom of said partition;the system further comprising:a second elongate case mounted in said groove in said astragal adjacent the top of said partition;a second slide having a longitudinal axis and mounted to said second case for sliding relative to said second case, between a first position and a second position of said second slide, said second slide having a recess;a second lock bolt on said second slide and engageable with a second stationary lock base when said partition is moved to said position closing at least part of said opening;a second lever having a second arm and having a hub and mounted on said second slide, said second lever being operable between a first condition with said second arm received in said recess in said second slide, and a second condition with said second arm projecting in a direction transverse to the axis of said second slide, to enable use of said second arm to slide said second lock bolt into engagement with said second stationary lock base lock said partition in said position closing at least part of said opening.
