<p>TITLE: SNAP FASTENER A class of snap fasteners is described each of which includes at least one male and at least one female member. The female members have at least one socket portion which may be in the nature of a cavity in a hollow housing accessible by a fenestration in a face wall which is normally exposed or accessible, or may be in the nature of a through-hole in a substantially solid elongated bar member. The male members have least one insert portion configuration and dimensioned to be receivable within portion configurated and dimensioned to be little clearance. Retainers are provided which limit free movement of the insert portions into and out of the socket portions. In the preferred embodiment, the retainers are in the nature of at least one protuberance or nipple at the fenestration or access opening to the socket portion which forms a local construction of the fenestration area to provide an interference fit when the insert portion passes through the fenestration. By making either one of the portions or the retainers out of a resilient material, the insert portions can be snapped into engagement with the members in substantially parallel planes throughout the joining operations. Other protuberances may be provided to improve the snap connection as well as to positionally stabilize the members once joined. The male and female members are provided with suitable connecting means for attachment to the parts to be releasably joined by the snap fastener, and are adapted to be gripped to permit the members to be separated without applying excessive stresses to the parts to be joined.</p> |
