Abstract
A quick-acting panel fastener assembly for joining a panel to a sub-structure is disclosed. The fastener assembly includes a sleeve bolt, a grommet assembly which is attached to the panel and a receptacle assembly which is attached to the sub-structure. The sleeve bolt passes through the grommet assembly and engages the receptacle assembly thereby joining the panel and the sub-structure. The grommet assembly includes a retainer ring which engages a groove in the sleeve bolt when it is in its withdrawn position so that the sleeve bolt is retained in the panel and remains in its withdrawn position when the panel is disengaged from the sub-structure.
Claims12
An improved quick-acting fastener assembly for joining a panel to a substructure including a grommet assembly having an annular body which is adapted to be secured to the panel and an annular resilient retainer having a split therein, said annular body being adapted to receive said retainer;
- a receptacle assembly which is adapted to be connected to the substructure including a threaded stud;
- and a threaded sleeve bolt having a head at one end formed to abut the panel and adapted to threadably engage said stud, said sleeve bolt having an annular groove adjacent the other end thereof and being adapted to be engaged by said retainer at said groove to secure said sleeve bolt to said grommet assembly when said sleeve bolt is threadably disengaged from said stud, the improvement characterized in that said annular body includes an annular cavity which is adapted to receive said retainer, said cavity having an outwardly sloping surface forming an angle x greater than zero degrees with respect to a plane perpendicular to the centerline of said body.
