1,242,322. Releasable fastenings. W. H. KOZLOWSKE and P. C. TABOR [trading as METEOR RESEARCH Ltd]. 29 May, 1969, No. 27214/69. Headings E2A and E2B. A tilt-plate fastener has a support 12, a fulcrum abutment 38 carried by said support, an apertured tilt plate 30, and spring means 34 engaging said plate in a region laterally displaced from said abutment toward the aperture in said tilt plate and urging said plate to engage said abutment and tilt thereon to frictionally bind a pin 4 in said aperture, said abutment being movable with respect to said support to thereby permit said plate to move to a non-tilted position to release the pin. In the construction shown a plurality of tilt plates are used to dispose one below the other with the topmost one in engagement with the fulcrum abutment and the support and the spring in engagement with the bottommost one to press the plates together. The abutment 38 is provided by a shaft 40 which is cut away over a length sufficient to extend the entire width of the tilt plates and so that the member has a semicylindrical cross sectional shape with its flat surface passing substantially through the axis of the shaft; the plates are in the non tilted position when the flat surface is in engagement with the topmost plate and they are in the tilted position when the shaft is rotated through 90‹ from such position. The shaft 40 can be connected to a cylinder lock mechanism and can be used to fasten a boot lid in place on a vehicle.
