Tension latch assembly
First Claim
1. A latch assembly for latching a first member to a second member comprising a relatively elongated latch sub-assembly and a strike, said latch sub-assembly being adapted to be mounted on one member and said strike on the other member in longitudinally aligned relation, said latch sub-assembly having a proximal end adapted to be positioned adjacent said strike and a distal end remote therefromsaid latch sub-assembly including in nested relation a case, a lever and a latch, each of said base and lever being U-shaped in transverse section,said lever having a handle bight and two side flanges depending therefrom, pintle means pivotally mounting said lever in said case adjacent the proximal end thereof with the lever side flanges being within the case flanges, a longitudinally arcuate leaf spring latch having a pair of sides, a hook adjacent the proximal end thereof and a pivot mounting adjacent the distal end thereof, pin means pivotally mounting said latch in said lever intermediate the ends thereof, said pintle means and pin means cooperating to develop over center action in said lever, said handle bight extending from the lever distal end to a position adjacent said pin means,said strike also having upstanding side flanges, the lever side flanges having proximal ends adjacent the distal ends of said strike side flanges, said strike flanges and lever flanges being in covering relation to said latch sides, andlock means adjacent the distal end of said case for releasably locking said case and lever together in nested relation and for preventing pry bar use by an intruder.

Abstract
A latch incorporates a latch member in the form of a leaf spring which is connected by an overcenter operating lever mechanism to a case mounted to a door for latching engagement with a strike mounted to another door or frame member. The strike incorporates guide rails for guiding the latch member into engagement with the strike, and the case includes an upstanding part for receiving a part of a lock with another part of the lock extending through an opening in the lever mechanism.

4. A latch assembly for latching a first member to a second member, comprising in combination:
-
a case adapted to be mounted to said first member, said case including a bight and two upstanding side flanges, a strike adapted to be mounted to said second member, a lever pivotally mounted on said case and disposed between said side flanges, a latch in the form of a leaf spring, and means pivotally mounting said latch to said lever, said latch having a hooked end portion for selective engagement with said strike to latch said first and second members together, fastener means attaching said strike to said second member, said latch covering said fastener means when said latch is engaged with said strike, said latch and said lever being pivotally mounted for respective pivotal movement about mutually parallel axes, an upstanding part of said case having an opening therethrough for receiving the shackle of a padlock, and an opening in said lever for receiving said shackle when said latch is in the latching condition, and said upstanding part of said case being generally planar, located midway between said case side flanges and lying in a plane perpendicular to said case side flanges. - View Dependent Claims (5)
