Abstract
Abstract A one-piece molded plastic upholstery button for receiving a loop of cord is disclosed. The button has a shank with a terminal portion which extends back toward the head of the button and which has a tongue on it that is closely spaced to a stop member to form an entrance gap to a cord receiving channel. A protuberance adjacent the bottom of the channel serves to lock the cord in place at the bottom of the channel.

A molded plastic upholstery button for receiving a loop of a cord comprising a head, a shank having a body which extends axially from said head and which has a terminal portion that extends back toward said head from a bight segment of said shank with said terminal portion beginning at said bight segment, a tongue formed on the end of said terminal portion which extends toward said head in said axial direction, a stop positioned outwardly of said tongue and extending from said head in said first direction to a point adjacent said tongue so as to form an entrance gap that has a width that is less than the thickness of said cord, there being an open channel of substantially uniform thickness which is of approximately the same width as said cord, said channel leading generally in said first direction from said first gap inwardly of said tongue and said terminal portion and away from said head to the end of said channel at said bight portion and a protuberance extending from said shank toward said terminal portion at a point adjacent said end of said channel to form a locking gap of a width which is less than the thickness of said cord so that said cord may thereby be secured into place at said end of said channel.
