Abstract

Abstract A button particularly for pillows and mattresses comprises a wide base portion with a hook shank connected to and extending out of the base portion and being curved around to enclose a hook loop. The interior of the shank within the loop is provided with an outwardly extending spring catch which extends partly across the open end of the loop. The outer leg of the hook shank extends backwardly toward and substantially perpendicular to the base and overlies and covers the spring catch. This outer leg portion has a terminal part which is made of triangular configuration with the sides diverging from the triangular in a direction toward the base so that the base of the triangular configuration is adjacent the button base.
