599,204. Hook fastenings ; hinges. BASSICK CO. June 11, 1945, No. 14712. Convention date, June 12, 1944. [Classes 44 and 65 (ii)] A toggle hook fastening for box lids and the like which may also, in the fastened position, serve as a hinge, comprises a pin carried by the lid and seating, when the lid is closed, on a member fixed to the box body, the pin being held on its seating by an extensible spring hook member operated by a rigid lever. As shown, a plate 16 secured to the lid B by screws 17 has depending spaced lugs 18, bent away from the lid and having their ends curled round a pin 15 bridging the space 20 between the lugs. The pin is rotatable in the lugs, endlong movement being prevented by pin-heads 19. When the box is closed the pin 15 seats in notches 14 provided in the upwardly extended ends of side flanges 13 upstanding from the base 10 of a channel-sectioned fixture secured to the box body. The rigid operating lever is of channel section, its side members 24 being extended and pivoted on a pin 26 between the flanges 13. The pin 15 is engaged and retained on its seats 14 by the hooked free end 28 of a member 22 of leaf spring material pivoted on a pin 30 between the lever flanges 24, the member being bowed at 22a. The base 23 of the operating lever channel is extended and outwardly curved at 27 to facilitate manipulation by finger. When the lever is depressed into contact with the box to effect fastening, the member 22 is extended somewhat as the lever passes over dead-centre to retain it resiliently in fastened position.
