Abstract

921,283. Releasable fastenings. ALLOM BROS. Ltd. Jan. 12, 1962, No. 1305/62. Addition to 894,684. Class 44. A fastening for releasably securing an electric light or other fitting to a support comprises a base member 1 adapted to be attached to the support, a catch member 7 which is guided for longitudinal movement on the base member between a locking position and a release position, the catch member when in the release position being capable of limited lateral movement for releasable engagement with the fitting and a spring 16 acting in effect directly between the base member and the catch member resiliently to restrain the catch member in both its locking and release positions from the longitudinal movement. The base member is a flanged plate having an L- shaped slot 5 which guides the catch member. An arm 15 is pivotally connected to the catch member by means of a nut and bolt assembly 14 which also passes through the slot 1 to connect the catch member to the base member. The free end of the arm passes through an aperture 6 of a lug 2 of the base member and supports the spring 16 which is trapped between the lug 2 and a shoulder 15<SP>1</SP> on the arm.
