Features for convenient mortise lock installation

Abstract

A mortise lock assembly for a door, including a casing, a locking mechanism arranged at least partly within the casing, and a plurality of location elements extending from the rear wall, for indicating a position for forming a recess in the door for receiving the lock assembly. Other non-limiting features allow the lock installer to decide what spring strength to give the handle of the mortise lock without having to carry two different locks in stock. Another non-limiting feature is an external sensor module that permits adding a microswitch or other sensor without having to provide it inside the lock.

Description

technical field [0001] The present invention relates generally to mortise lock assemblies and devices for conveniently installing mortise locks. Background technique [0002] One of the most widely used forms of locks is the mortise lock. The mortise lock assembly fits into a mortise in a groove opening in the side of the door, ie the side of the door, which abuts against the edge of the adjacent surface of the side door wall when the door is closed. Since the body of the lock, including most of the working parts, is within the door itself, it is difficult for an intruder to gain access to these working parts, and thus it is difficult for an intruder to gain unauthorized access to a locked room or area. [0003] In order to install a mortise lock, a suitably configured groove ("mortise") for receiving the lock must be formed in the open side of the door. The formation of the mortise is a rather cumbersome process and requires relatively precise positioning of the mortise r...

There is therefore a need for a mortise lock of simple construction, but nonetheless comprising sensor means for monitoring whether the lock is in the locked position
