Abstract
A door handle and lock body housing combination is provided. The lock body housing (1) has a rectangular shaped base configuration (5) which has a length approximately equal to the length of a handle (3) which extends therefrom in a direction generally parallel to the planar base (5). The height and width of the lock body housing (1) is sufficient to wholly accommodate a lock barrel (7) which extends from a front face of the housing (1). The handle (3) is generally "D"-shaped and wherein there is a greater distance behind the handle to the bottom of the planar base (5) at a central region (45) of the handle (3) than at the outer end regions (49) of the handle (3). The combination is formed of plastics material and lock security is enhanced by providing a metal base (5) to which a lock catch member (67) is attached, and a generally "L"-shaped cross-section metal cover which has one leg extending over a leading face ( 23) of the housing (1) and through which the locking tongue (11) of the lock catch member (67) passes, and where the other leg extends over a front face of the housing (1) to incorporate a front face of the lock barrel (7).
