Fastener with wire-form holdout

Claim 2

An aircraft panel fastener with a wire-form holdout comprising: (a) a stud-like fastener body, (b) said body having a central bore extending inwardly from its forward end, (c) a longitudinal slot on said fastener body communicating with said bore, (d) a generally U-shaped wire spring member having two legs with one leg extending outwardly and then inwardly forming a curved, protruding bearing surface thereon, (e) said spring member housed in said bore with the bearing surface extending through said slot beyond the periphery of said fastener body and with the opposite leg of said member bearing against the opposite bore wall of the fastener bore, (f) said bearing surface of said spring member biased outwardly but deflectable inwardly through said slot, and (g) said opposite leg formed with a hook at its lower end to facilitate the removal of the spring member from the bore.

Claim 3

The fastener of claim 1 wherein said spring member is formed with a coil at its closed end.

Claim 4

An aircraft panel fastener with a wire-form holdout comprising: (a) a stud-like fastener body, (b) said body having a central bore extending inwardly from its forward end, (c) a longitudinal closed-ended slot on said fastener body communicating with said bore, (d) a generally U-shaped wire spring member having two legs with one leg extending outwardly and then inwardly forming a curved, protruding bearing surface thereon, (e) said slot having a width slightly wider than the diameter of said wire spring member, (f) said spring member freely housed entirely within said bore with the bearing surface extending through said slot beyond the periphery of said fastener body and with the opposite leg of said member bearing against the opposite bore wall of the fastener bore, (g) said bearing surface of said spring member biased outwardly but deflectable inwardly through said slot, (h) stop means slidably carried on said fastener for retaining said fastener to said panel, (i) said fastener carried within a fastener opening in said panel, (j) said fastener slidable within said fastener opening and having a retracted position when pulled outwardly to the extent permitted by the stop means, (k) said bearing surface arranged with respect to said stop means to come in contact with the wall of said fastener opening when said fastener is in its retracted position, and (l) said fastener held outwardly by the contact of said bearing surface with the wall of the fastener opening.

Claim 5

An aircraft panel fastener with a wire-form holdout comprising: (a) a stud-like fastener body, (b) said body having a central bore extending inwardly from its forward end, (c) a longitudinal closed-ended slot on said fastener body communicating with said bore, (d) a generally U-shaped wire spring member having two legs with one leg extending outwardly and then inwardly forming a curved, protruding bearing surface thereon, (e) said slot having a width slightly wider than the diameter of said wire spring member, (f) said spring member freely housed entirely within said bore with the bearing surface extending through said slot beyond the periphery of said fastener body and with the opposite leg of said member bearing against the opposite bore wall of the fastener bore, (g) said bearing surface of said spring member biased outwardly but deflectable inwardly through said slot, (h) stop means slidably carried on said fastener for retaining said fastener to said panel, (i) said fastener carried within a fastener opening in said panel, (j) said fastener slidable within said fastener opening and having a retracted position when pulled outwardly to the extent permitted by the stop means, (k) said bearing surface arranged with respect to said stop means to come in contact with the wall of said fastener opening when said fastener is in its retracted position, and (l) said fastener held outwardly by the contact of said bearing surface with the wall of the fastener opening.

Claim 6

The fastener of claim 3 wherein said stop means is defined as a retaining ring.

Claim 7

The fastener of claim 3 wherein said spring member is formed with a coil at its closed end.

Claim 8

The fastener of claim 3 wherein said fastener is further defined as having first and second closed-ended longitudinal slots carried on said fastener body in communication with said fastener bore, said U-shaped wire spring member having a protruding bearing surface on each of said legs, one of said bearing surfaces extending through the first of said slots beyond the periphery of the fastener body and the other of said bearing surfaces extending through the other of said slots beyond the periphery of the fastener body, each of said bearing surfaces biased outwardly but deflectable inwardly through said respective slots, and said fastener restrained against vertical movement by the contact of the bearing surfaces with the sidewall of the panel fastener opening when said fastener is in said retracted position.
