Sliding window or door lock
First Claim
1. A lock including a body which is adapted to be secured to one of two relatively movable members, said body having a mounting part and an actuator part, a locking bar mounted on said actuator part for relative axial movement between an operative position in which an end portion of said bar projects beyond a back surface of said actuator part for location within a hole provided in the other of said two members and an inoperative position in which said end portion does not so project, locking means carried by said actuator part and being operable to hold said locking bar against movement from the operative to the inoperative position, said mounting part projecting laterally from one side of said actuator part in a direction transverse to the longitudinal axis of said bar, and having four sides which extend in that direction, two of said four sides constituting substantially parallel front and back sides of the mounting part and each of the other two said sides extends between said front and back sides in substantially parallel relationship, said front and back sides being spaced apart in the axial direction of said locking bar, at least one primary fastening bore extending through said front and back sides of the mounting part, and at least one secondary fastening bore extending through said other sides of the mounting part in a direction transverse to the axis of said primary fastening bore and also transverse to said direction of projection of said mounting part, the arrangement being such that said lock can be secured either to an outwardly facing surface of said one member or to a surface which extends transverse to said outwardly facing surface, and in the former case said mounting part projects outwardly from said outwardly facing surface and is secured thereto by fastening means (for securing said body to said one member can be associated with either said primary or secondary bore whereby said body can be secured to a surface of said one member which is either parallel to or transverse to said locking bar axis) extending through said primary fastening bore, whereas in the latter case said mounting part is located to one side of said outwardly facing surface and is secured to said transverse surface by fastening means extending through said secondary bore.

Abstract
A lock for a sliding window or door and having a body which is adapted to be secured to either an outwardly facing surface or a laterally facing surface of the movable frame of the window or door. The lock includes a locking bar which is slidably mounted on the lock body for relative movement into and out of an operative position at which it projects beyond a back surface of the lock body and engages within a hole in the fixed frame of the window or door. The lock body is secured to the movable frame by means of fastening screws extending through bores formed through a mounting part of the body and those bores include primary bores which extend in the front to back direction and secondary bores which extend laterally through the mounting part. The primary bores are used if the body is to be secured to the outwardly facing frame surface and the secondary bores are used if the body is to be secured to the laterally facing frame surface. The fixing means may include an expandable nut located in the movable frame and which is expanded into tight engagement with that frame by interaction between an end of the screw and a tapered section of a bore of the nut.
