Abstract

1,258,997. Releasable fastenings. SERCK INDUSTRIES Ltd. 20 Oct., 1970 [20 Nov., 1969], No. 56927/69. Heading E2B. [Also in Division F2] An over-centre fastener comprises a lever 6 adapted to be pivotally mounted adjacent to one end thereof on one, e.g. a door 12 of a pair of members to be secured together the lever being formed between the pivot and the other end thereof with a hook, and an eyelet 9 on the other of the pair of members. The arrangement is such that when the two members are disposed with the hook and eyelet adjacent to one another the hook can be engaged in the eyelet so that subsequent rotation of the lever in one direction will draw the two members towards one another and will cause the lever to assume a stable "over centre" position. As shown, the eyelet 9 is mounted on a member screwed into a support block 11 secured to the door frame 2, the door hinges 5 being similarly adjustable. The door has a channel portion 22 receiving a deformable gasket 1, and may have an insulating slab 10 held in position by a lagging plate 4. The frame 2 of channel section may be replaced by one of angle section.
