Abstract
Abstract A two-part releasable fastening device for connecting strap or band portions of wearing apparel comprises two separate and identical component parts which slot and interlock together and which each consist of a plate member having a substantially planar body portion and an adjacent substantially planar offset coupling portion integrally interconnected by a transverselyextending cranked portion substantially in alignment with a reentrant transversely-extending open-ended coupling slot. The coupling portion provides a relatively narrow transverselyextending tongue terminating in a latching projection or tab which establishes additional interlocking engagement with the other component part, and the plate member of each part may have a shallow curvilinear form in longitudinal cross-section.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
357 words
A fastening device usable for connecting together respective free end portions of strap portions of articles of wearing apparel, said fastening device consisting of two identical separate component parts which releasably couple by slotting together to produce an interlocking fastening engagement, each said component part comprising a sheet-metal plate member having a substantially planar body portion, slot means for securing to said body portion a respective free end portion of the strap portions to be connected, a substantially planar coupling portion adjacent to but offset from the general plane of said body portion, a cranked portion providing a shallow step integrally interconnecting said body portion and coupling portion and extending in a direction transversely across the plate member, a re-entrant transversely-extending open-ended coupling slot which is substantially in alignment with said cranked portion and which extends as far as a median longitudinal axis of the respective plate member, said coupling portion of each component part including a transversely-extending tongue which is narrow relative to the width of said body portion and which bounds one side of said re-entrant coupling slot, said coupling portion of each component part further comprising a latching tab formed by a rearwardly-directed projection at a free extremity of said transversely-extending tongue, said tab being adapted to latchably engage a recessed edge portion of the plate member of the other component part when said two component parts are fully coupled together to establish an additional interlocking engagement, said coupling portion of each component part further having reinforcing rib means extending into said tongue in the direction of the length of said tongue, and said body portion of each plate member having fIrst and second edge portions bounding the second side of the re-entrant coupling slot adjacent the inner and outer ends respectively of said slot, said first edge portion being parallel to the tongue and to the axis of said slot and said second edge portion being at an oblique angle to the tongue and to the axis of said slot thereby to provide a tapering entrance to said slot and provide a guide surface to facilitate coupling engagement of the two component parts.
Claim 2
Dependent Claim
357 words
A fastening device usable for connecting together respective free end portions of strap portions of articles of wearing apparel, said fastening device consisting of two identical separate component parts which releasably couple by slotting together to produce an interlocking fastening engagement, each said component part comprising a sheet-metal plate member having a substantially planar body portion, slot means for securing to said body portion a respective free end portion of the strap portions to be connected, a substantially planar coupling portion adjacent to but offset from the general plane of said body portion, a cranked portion providing a shallow step integrally interconnecting said body portion and coupling portion and extending in a direction transversely across the plate member, a re-entrant transversely-extending open-ended coupling slot which is substantially in alignment with said cranked portion and which extends as far as a median longitudinal axis of the respective plate member, said coupling portion of each component part including a transversely-extending tongue which is narrow relative to the width of said body portion and which bounds one side of said re-entrant coupling slot, said coupling portion of each component part further comprising a latching tab formed by a rearwardly-directed projection at a free extremity of said transversely-extending tongue, said tab being adapted to latchably engage a recessed edge portion of the plate member of the other component part when said two component parts are fully coupled together to establish an additional interlocking engagement, said coupling portion of each component part further having reinforcing rib means extending into said tongue in the direction of the length of said tongue, and said body portion of each plate member having fIrst and second edge portions bounding the second side of the re-entrant coupling slot adjacent the inner and outer ends respectively of said slot, said first edge portion being parallel to the tongue and to the axis of said slot and said second edge portion being at an oblique angle to the tongue and to the axis of said slot thereby to provide a tapering entrance to said slot and provide a guide surface to facilitate coupling engagement of the two component parts.
Claim 3
Dependent Claim
95 words
A fastening device according to claim 1 wherein the slot means in said body portion of each plate member comprises a closed slot to accommodate a looped end portion of the strap portion which is secured thereto, and each plate member further comprises a sheet metal tongue disposed in overlying relationship with said body portion and an arcuate bend portion integrally connecting said tongue to said body portion along an edge boundary of the closed slot, said bend portion providing a smooth curved bearing surface for engaging the looped end portion of the strap portion.
Claim 4
Dependent Claim
62 words
A fastening device according to claim 2, wherein the plate member of each component part has a shallow bent configuration in longitudinal cross-section whereby said two component parts when coupled together follow a shallow substantially arcuate contour so as to conform to curvature of the body of a wearer of an article of wearing apparel to which the fastening device is fitted.
Claim 5
Dependent Claim
62 words
