Abstract

Abstract A fabric-covered button includes a button body with a domed head to be wrapped by a piece of fabric, a retainer washer of synthetic resin adapted to fit forcibly over a boss projecting rearwardly from the domed head and to press an edge portion of the fabric piece against a peripheral flange of the domed head, and a fastener having a shank adapted to fit forcibly into an axial hole in the boss. Either the boss or the shank has at least one axial slot which allows air to escape from the hole in the boss when the shank is forced into the hole.

Claims Analysis

Total Claims: 14
Claim 1
Independent Claim 242 words
A covered button for attachment to a piece of cloth having a preformed aperture, comprising: (a) a button body including a domed head and a central boss projecting inwardly from said domed head and having a cylindrical outer surface and a cylindrical bore having a continuous circumferential wall and closed at its outer end, said domed head having an inwardly directed peripheral flange surrounding said central boss in spaced relation thereto; (b) a retainer washer of synthetic resin adapted to be mounted on said boss resiliently with a force fit and having an outer periphery adapted to coact with said inwardly directed peripheral flange of the domed head in gripping between the outer peripheral edge of said washer and a radially inner surface of said flange an edge portion of a piece of fabric extending over said domed head and in around said peripheral flange; and (c) a fastener having a base and a central shank projecting from said base and adapted to fit forcibly into said cylindrical bore in the central boss through an aperture in the piece of cloth to sandwich the piece of cloth between said base and said button body, one of said central shank and said boss having means for allowing air to escape from said bore when said shank is forced axially into said bore, said means comprising a passage extending axially between said shank and boss from the interior of said bore to the atmosphere.
Claim 2
Dependent Claim 242 words
A covered button for attachment to a piece of cloth having a preformed aperture, comprising: (a) a button body including a domed head and a central boss projecting inwardly from said domed head and having a cylindrical outer surface and a cylindrical bore having a continuous circumferential wall and closed at its outer end, said domed head having an inwardly directed peripheral flange surrounding said central boss in spaced relation thereto; (b) a retainer washer of synthetic resin adapted to be mounted on said boss resiliently with a force fit and having an outer periphery adapted to coact with said inwardly directed peripheral flange of the domed head in gripping between the outer peripheral edge of said washer and a radially inner surface of said flange an edge portion of a piece of fabric extending over said domed head and in around said peripheral flange; and (c) a fastener having a base and a central shank projecting from said base and adapted to fit forcibly into said cylindrical bore in the central boss through an aperture in the piece of cloth to sandwich the piece of cloth between said base and said button body, one of said central shank and said boss having means for allowing air to escape from said bore when said shank is forced axially into said bore, said means comprising a passage extending axially between said shank and boss from the interior of said bore to the atmosphere.
Claim 3
Dependent Claim 26 words
A button according to claim 1, said means comprising at least one slot extending axially in said boss and opening into said bore in said boss.
Claim 4
Dependent Claim 21 words
A button according to claim 1, said means comprising at least one slot extending axially in said shank of the fastener.
Claim 5
Dependent Claim 17 words
