Abstract
A lockable strike for walk-in cold rooms includes a housing that has a mounting plate, a cover and a deadbolt moveably engaged therein to reciprocally move along a path of travel between an extended position and a retracted position with respect to the housing. The mounting plate includes a base and a bridge defining a tongue channel through which the deadbolt travels. The mounting plate base is made of a metal for strength while the cover is made of a plastic for thermally insulative purposes.
Claims10
A lockable strike for walk-in cold rooms, comprising,
- a housing including a bottom mounting plate and a guide bridge extending from said bottom mounting plate and defining a guide channel, said bottom mounting plate includes a pair of guide rails oriented to guide said deadbolt through said guide bridge channel, and
- a locking mechanism including a laterally reciprocally moving deadbolt and a handle coupled to said deadbolt so that movement of said handle causes the lateral movement of said deadbolt, said laterally reciprocally moving deadbolt being mounted for lateral reciprocal movement within said guide channel of said guide bridge, said guide bridge being configured to overlie said deadbolt and to abut said deadbolt should a door opening pressure be applied to said deadbolt causing said deadbolt to be forced towards said bridge.
A lockable strike for a walk-in cold room structure, comprising:
- a mounting plate adapted to be mounted to the walk-in cold room structure, said mounting plate including a bracket, said mounting plate defining a deadbolt passageway passing below said bracket;
- a deadbolt tongue adapted for lateral movement through said deadbolt passageway between a locked position and an unlocked position, and
- a lock coupled to said deadbolt tongue to lock said deadbolt tongue in said locked position,
- said bracket being configured to overlay said deadbolt tongue while allowing reciprocal lateral movement of said tongue relative to said mounting plate
- whereby the deadbolt tongue is prevented from moving out of said deadbolt passageway by said bracket.
