Abstract
Abstract A two-part fastener for attaching two apertured panels together so that one panel is readily removable from the other, the fastener comprising a stud portion having a shank adapted for snap engagement rough a circular aperture in one of the panels, a flange at one end of the shank adapted to abut the outer surface of the said one panel to limit insertion of the shank therethrough and a stud projecting from the opposite side of the flange from the shank and adapted to project outwardly through a circular aperture in the other panel when the other panel is resting on the flange of the stud portion and a socket portion formed with a bore open at one end shaped to receive the stud of the stud portion and with an external flange which is spaced from the said one end of the bore and adapted to clamp the said other panel against the said flange of the stud portion, the stud and the bore in the socket portion being provided with means which interengage when the stud is within the bore to resist withdrawal of the socket portion from the stud.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
155 words
A two part fastener for attaching two apertured panels together, comprising a stud portion and a socket portion, the stud portion comprising a shank adapted to engage through an aperture in one of the panels, a flange at one end of the shank adapted to abut the outer surface of the said one panel to limit insertion of the shank therethrough and a stud projecting from the opposite side of the flange from the shank, the socket portion being formed with a bore open at one end to receive the stud of the stud portion and with a flange which is spaced from the said one end so as to limit insertion of the socket through the aperture in the other panel, wherein the stud and the socket portion are provided with means which interengage when the stud is inserted into the bore in the socket to resist withdrawal of the stud from the bore.
Claim 2
Dependent Claim
155 words
A two part fastener for attaching two apertured panels together, comprising a stud portion and a socket portion, the stud portion comprising a shank adapted to engage through an aperture in one of the panels, a flange at one end of the shank adapted to abut the outer surface of the said one panel to limit insertion of the shank therethrough and a stud projecting from the opposite side of the flange from the shank, the socket portion being formed with a bore open at one end to receive the stud of the stud portion and with a flange which is spaced from the said one end so as to limit insertion of the socket through the aperture in the other panel, wherein the stud and the socket portion are provided with means which interengage when the stud is inserted into the bore in the socket to resist withdrawal of the stud from the bore.
Claim 3
Dependent Claim
42 words
A fastener as claimed in claim 1, wherein the stud is formed with an annular shoulder facing the flange on the stud portion and a recess is formed in the wall of the bore in the socket to receive the said shoulder.
Claim 4
Dependent Claim
22 words
A fastener as claimed in claim 2, wherein the said shoulder comprises a face of an annular rib provided on the stud.
Claim 5
Dependent Claim
23 words
A fastener as claimed 3, wherein two diagonally arranged slots are formed through the wall of the socket to receive the annular rib.
Claim 6
Dependent Claim
40 words
A fastener as claimed in claim 1, wherein the stud is formed with a recess and the socket is formed with a projection extending radially inwardly from the wall of the bore which engages in the recess in the stud.
Claim 7
Dependent Claim
23 words
A fastener as claimed in claim 5, wherein the said recess is an annular recess and the said rib is an annular rib.
Claim 8
Dependent Claim
60 words
A fastener as claimed in claim 5, wherein the stud is generally cylindrical and formed with a circumferential recess and the socket is formed with a circumferential rib on the wall of the bore, the periphery of the rib being generally oval and adapted to deform as the stud is forced into the bore and snap engage into the recess.
Claim 9
Dependent Claim
28 words
A fastener as claimed in claim 1, wherein the stud is provided with a series of annular serrations which engage the wall of the bore in the socket.
Claim 10
Dependent Claim
