Two-piece Fastener
Disclosed is a fastener that comprises a stud member and a nut member. The stud member includes a base portion, a stem, a plurality of locating features, and, a plurality of slanted ridges. The stem has a head portion and a body portion, where the body portion is positioned on the base portion for enabling the stem to extend vertically from the base portion. The plurality of locating features extends from the body portion, and is disposed on the base portion. The plurality of slanted ridges extends from the stem. The nut member includes a central element configured to have two projecting members extending opposite to each other from a periphery of the central element. The central element comprises an aperture therewithin for receiving the stem therethrough and for interlocking the nut member with the stud member to retain the stud member at a locked configuration.
1. A fastener, comprising:
a stud member comprising
a base portion,
said base portion comprising a flat underside and a collar disposed on said flat underside,
a stem extending vertically from the base portion, the stem having a head portion and a body portion, wherein the body portion of the stem is positioned on the base portion for enabling the stem to extend vertically from the base portion,
a plurality of locating features extending from the body portion, and disposed on the base portion, such that, locating features of the plurality of locating features are spaced apart at a predetermined angle from each other, and
a plurality of slanted ridges extending from the stem, such that, slanted ridges of the plurality of slanted ridges are spaced apart at a predetermined distance from each other; and
a nut member comprising a central element configured to have two projecting members extending opposite to each other from a periphery of the central element, the central element comprising an aperture therewithin for receiving the stem therethrough for interlocking the nut member with the stud member to retain the stud member at a locked configuration,
wherein the two projecting members comprise a structure substantially similar to a hourglass structure when said stem of said stud member is not received through said nut member, and
wherein one of the projecting member may be flattened when said stem of said stud member is received through said nut member.
2. The fastener of claim 1 , wherein the plurality of slanted ridges extends from two opposite sides of the body portion of the stem.
3. The fastener of claim 1 , wherein the aperture of the central element of the nut member is capable of aligning with the head portion of the stem for downwardly sliding the nut member for receiving the stem therethrough and for interlocking the nut member with the stud member to retain the stud member at the locked configuration.
4. The fastener of claim 1 , wherein a pair of ridges of the plurality of ridges rests on a portion of the central element, when the stem is received through the aperture and a projecting member of the two projecting members is flattened to retain the stud member at the locked configuration.
5. The fastener of claim 1 , wherein the stud member is made of a plastic material.
6. The fastener of claim 1 , wherein the nut member is made of a plastic material.
