Rotary engageable lever actuated fastener assembly

Abstract

Abstract A FASTENER ASSEMBLY WHICH INCLUDES INTERENGAGABLE RECEPTACLE AND OPERATING HANDLE MEMBERS IN WHICH THE RECEPTACLE MEMBER HAS A RELATIVELY FIXED SUPPORTING BASE PORTION, A DETENT PORTION INCLUDING A CROSSPIN OR ROD MOUNTED ON SAID BASE PORTION AND SPRING MEANS INTERPOSED BETWEEN SAID BASE AND DETENT PORTIONS WITH THE DETENT PORTION BEING SHIFTABLE RELATIVE TO THE BASE PORTION FROM A NORMAL POSITION WITH THE SPRING MEANS BEING RELATIVELY EXPANDED TO A FASTENER LOCKED POSITION WITH THE SPRING MEANS RELATIVELY CONTRACTED. THE OPERATING HANDLE IS IN TURN PROVIDED WITH AN OPERATING LEVER PORTION SHIFTABLE BETWEEN OPEN AND CLOSED POSITIONS AND ALSO WITH A CAM PORTION IN THE FORM OF A STUD, HAVING A TRANSVERSE SPIRAL CAM SLOT, PIVOTABLY DEPENDING FROM THE LEVER PORTION. WHEN THE LEVER IS IN OPEN POSITION THE CAM PORTION CAN BE ENGAGED WITH THE DETENT PORTION BY INSERTING THE SPIRAL CAM SLOT OVER THE CROSSPIN AND ROTATING THE ENTIRE OPERATING HANDLE ASSEMBLY SO THAT THE SLOT AND CROSSPIN ARE INTERENGAGED. THE FASTENER ASSEMBLY IS THEN LOCKED BY SHIFTTING THE OPERATING LEVER TO CLOSED POSITION WHICH IN TURN CAUSES THE DETENT PORTION TO SHIFT TO RELATIVELY SPRING CONTRACTED POSITION THEREBY HOLDING THE ASSEMBLY IN CLOSED OR LOCKED POSITION UNDER SPRING TENSION.
