Abstract
Abstract A SNAP-IN SCREW CAPTIVATING DEVICE IS INSERTED INTO A HOLE IN SHEET MATERIAL TO BE SECURED BY THE SCREW AND IS FORMED OF RESILIENT MATERIAL IN THE GENERAL CONFIGURATION OF A SLOTTED CYLINDER HAVING A SCREW HEAD RECEIVING CHAMBER. THE CAPTIVATING DEVICE FITS WITHIN THE HOLE IN THE SHEET MATERIAL AND EXPANDS TO ENGAGE THE E EDGES OF THE HOLE. THE UPPER EDGES OF THE CHAMBER BEND INWARDLY A SHORT DISTANCE INTO THE CHAMBER TO FORM A LEDGE, AND THE SCREW IS PUSHED PAST THIS SLOTTED LEDGE CAMMING IT OUTWARDLY TO ALLOW THE HEAD TO PASS, WHEREUPON THE CHAMBER RESUMES ITS ORIGINAL POSITION. THE CHAMBER MAY BE EXTENDED TO PERMIT BACKING OUT OF THE SCREW FROM THE THREAD AND TO PROVIDE SPACE FOR A SNAP BUTTON TO BE PLACED ON TOP OF THE SCREW HEAD. WHEN THE BUTTON IS IN PLACE, THE BUTTON ALSO IS CAPTIVATED BY THE ACTION OF THE CAPTIVATING DEVICE HOLDING THE BUTTON IN PLACE.
