A keep arrangement for a lock comprises a mounting part 36 for mounting the keep to a surface such as a window or a door frame. A slotted keep part 38 is provided for receiving a headed bolt 16 of a lock such as an espagnolette and is movable relative to the mounting part 36. Resilient members 40, such as compression springs are arranged between the mounting part 36 and the keep part 38. In figure 6b resilient members 40 accommodate changes in the spacing between the keep and mounting parts. In the figure 8 arrangement a keep part 62 slotted at 74 to receive headed bolts is located on a mounting part 50 and resilient members 78 allow sideways movement. The headed bolt can be resiliently mounted on a support pin and as shown in figure 11 a lock keep 104 comprises a body 106 defining a first pathway 112 for receiving a first bolt and a second pathway 114 for receiving a second, relatively movable, bolt. The bolt in pathway 116 can be moved into passages 118 or 120 to provide locking in full or partial closure positions and a supplementary locking member engaged by this bolt movement can secure the other bolt in pathway 112. |
