Abstract
A door lock has a body portion securable to a door jamb so as to project therefrom into a room, and a locking portion pivotally mounted on the body portion for angular movement relative thereto about a vertical axis between a locking position preventing opening of a door and an unlocking position permitting opening of the door. One of the portions has a projection engageable in a recess in the other portion to retain the locking portion in the locking position. The locking portion is capable of a limited amount of transverse movement relative to the body portion in a horizontal direction substantially perpendicular to the direction of opening movement of the door to enable the projection to be engaged in and disengaged from the recess.

- a locking portion pivotally mounted on the body portion for angular movement relative thereto about a vertical pivot axis, when the body portion is secured to the door jamb, between a locking position engaging and preventing opening of a door and an unlocking position permitting opening of the door,
- one of said portions having a projection engageable in a recess in the other portion to retain the locking portion in the locking position, and
- said locking portion being capable of a limited amount of transverse movement relative to the body portion in a horizontal direction substantially perpendicular to the direction of opening movement of the door to enable the projection to be engaged in and a plane through the vertical pivot axis and perpendicular to the door, when closed, establishing the door on one side of the plane
- said projection and said recess being located, when said projection is engaged in said recess, on the same side of said plane through said vertical pivot axis as the door.
