A stored energy torsional rotary fastener device providing ready releasable attachment of first and second components. A fastener housing, attached to the first component, includes a cylindrical socket having an upper open end and a lower end configured by a pair of base segments defining a cross-slot the parallel edges of which are formed with concentrically disposed arcuate cutouts. The segments have interior helical pitched ramp portions establishing an interrupted thread support. A rotor, including an axial stem terminating in a radial disc axially positioned in the socket, is rotatably biased by a coiled spring interconnecting the rotor and housing. The rotor disc is formed with a depending axial hub having its lower portion journalled in the slot cutouts. The hub upper end includes oppositely extending radial lugs, with each lug underface formed with a helical pitch adapted to mate with an associated ramp portion, enabling axial threaded rotor travel. The hub terminates in an annular shoulder, encircling a lower axial stem, which stem ends in a cross-head adapted to extend through the cross-slot, with the cross-head providing an upwardly facing engaging surface. Threading the rotor in one direction advances it to a “cocked and armed”mode with the lugs having diametrically opposite corner junctures rotatably biased against an associated cross-slot edge. Upon the cross-head being inserted through a second component mating slot the shoulder is displaced upwardly releasing the lugs, whereby the spring threads the rotor in the opposite direction such that the cross-head urges the components into engagement.

A quick-connect fastening device for releasably securing first and second components comprising: a housing adapted to be secured to the first component, said housing formed with a cylindrical socket aligned on a principal axis, said socket being open at one end while its opposite end is formed with a pair of base segments defining a cross-slot having parallel edges symmetrically disposed about a socket diametrical axis, opposed arcuate cutouts concentrically formed in associated ones of said cross-slot edges, each said segment having an interior spiral ramp portion with said ramp portions providing a helical pitch thread support; a rotor concentrically disposed in said socket, said rotor rotationally biased by spring means interconnecting said rotor and said housing, said rotor formed with a first stem having one end extending in one axial direction to said socket open end and an opposite end terminating in a radial disc, a concentric hub, extending from an underside of said disc, is journalled in said cutouts; a pair of opposite lugs extend from said hub and are symmetrically disposed about a socket diametrical axis, each lug having an underface formed with a helical pitch surface mating with an associated ramp portion for axial threaded rotor travel; said hub having a distal annular shoulder from which a second stem extends to said socket opposite end terminating in a latching cross-head adapted to extend through said cross-slot and having engaging surface means in opposed axially spaced relation to said shoulder, said cross-head being aligned on a socket diametrical axis normal to said lug diametrical axis; said rotor adapted to be threaded in one rotational direction to a “cocked and armed”mode with said hub shoulder disposed axially below said segments with each lug rotationally biased against an opposed cross-slot edge; whereby upon said cross-head being inserted through a second component slot the second component engages said hub shoulder and displaces said rotor in said one axial direction, such that each lug clears its associated cross-slot edge thereby releasing a portion of the spring means stored energy and threads said rotor in an opposite rotational direction through a predetermined angle, whereby said cross-head engaging surface means urges said second component into releasable engagement with said first component.
