Abstract

1442770 Lighting fittings KAISER & CO LEUCHTEN KG LICHTTECHNISCHE SPEZIALFABRIK Gebr 5 Oct 1973 [5 Oct 1972] 46574/73 Heading F4R [Also in Division E2] A lighting fitting comprises a mounting part 11 adapted to be fixed to a ceiling and a lamp housing part 12 which is releasably secured to the mounting part by a lock, the lock consisting of an elongate locking member 15 connected to one of the parts and a catch member 14 connected to the other part, the elongate locking member moving freely longitudinally into the catch member when the housing part 12 is moved towards the mounting part 11 but the lock preventing movement of the parts away from one another in a plurality of positions of the catch member along the locking member. The locking member is preferably in the form of a bolt the shank 26 of which has teeth around part of its circumference and at least one flat side (27), and the catch member is a sheet of spring metal having an opening for the bolt and at least one resilient tongue 23 adapted to engage the teeth and prevent withdrawal of the bolt. The bolt may be released by rotating its shank until the flat side (27) faces the tongue 23. In a modification the shank is smooth and forms, with the catch member, a friction lock. The head 31 of the bolt is eccentric and serves to support releasably an accessory 36 having a correspondingly shaped hole (37).
