Abstract:
A quick releasable mounting for window guards comprising:an elongated cylindrical casing, having a first end, a second end, an interior and exterior, said exterior is threaded at said first end extending inwardly to a predetermined distance, ending and mating with a substantially smooth surface, wherein said smooth surface extends from said predetermined distance to a second end, said elongated cylindrical casing has an interior slotted cavity wherein said cavity is concentrically divided by a first shoulder and a second shoulder, wherein said second shoulder is substantially larger then said first shoulder, each of said shoulders respectively have, a chamfered front end, and a flat-faced rear end, said first shoulder is located proximately adjacent said predetermined distance of said threaded first end and said smooth surface interface, said second shoulder is located central to said elongated cylindrical casing;a threaded flange wherein said threaded flange has an interior thread diameter substantially equal to an outer diameter of said threaded first end upon said exterior of said elongated cylindrical casing;a resilient cap, having an interior cavity with an internal diameter substantially equal to said exterior diameter of said threaded first end of said elongated cylindrical casing, extending from a base inwardly to a crown of said resilient cap, wherein said cavity has a threaded interior diameter extending from said base inwardly toward said crown of said resilient cap, said crown has a symmetrical recess, straddling an extruded central portion of said cap, said resilient cap has a means for threaded fastening to said threaded first end of said elongated cylindrical casing wherein said base of said resilient cap seats sufficiently flush to said threaded flange;a retractable flat locking member slidingly disposed within said interior slotted cavity of said elongated cylindrical casing wherein said retractable flat locking member has a pair of scissor tails extending from a bisecting shank connected to a base wherein said base has a notched distal end, at least one of said scissor tails has a periphery with a chamfered outside edge juxtaposed adjacent to said first shoulder of said elongated cylindrical casing, said bisecting shank is disposed between said second shoulder of said elongated cylindrical casing;a flat tail key having a circular base wherein said flat tail key tapers inwardly and into a rounded terminal end, in an axial direction from said circular base to a distal position, wherein said distal position is central to said scissor tail of said retractable flat locking member wherein said rounded terminal end is adapted to slidingly engage an interior portion of said scissor tails forcing said peripheries of said scissor tails into a trapped position adjacent said first shoulder of said elongated cylindrical casing, said circular base seats adjacent to said crown of said resilient cap, flush with said extruded central portion therefor;a flat bracket connector having a concentric circular flange disposed between an inverted and inwardly extending notched end and an outwardly extended flat slotted end wherein said flat slotted end is shouldered by a step, said inverted and inwardly extended notched end is adapted to mate with said notched distal end of said retractable flat locking member within said interior slotted cavity of said elongated cylindrical casing, wherein said concentric circular flange seats adjacent to an outer rim of said second end of said elongated cylindrical casing; anda pair of compression springs, wherein a first compression spring is positioned between said base of said flat tail key and said threaded first end of said elongated cylindrical casing and a second compression spring disposed between said flat-faced rear end of said second shoulder and a shank-side edge of said base of said retractable flat locking member, said first compression spring is adapted to urge said flat tail key outwardly from within said interior portion of said scissor tails, said second compression spring is adapted to urge said retractable flat locking member outwardly from within said elongated cylindrical casing, said compression springs are adapted to disengage said mated notched ends.
