发明名称 WEBB FASTENERS
摘要 An improved web fastener for use in securing webs to tubular chair frames and the like. The improved fastener includes a tongue which is struck from the fastener and which has the first portion projecting outwardly from the body of the fastener. The outer end of the tongue is generally V-shaped when viewed from above and at least one additional portion is integrally connected to the first portion along one of the inclined leading edges and projects rearwardly therefrom. The tongue may also include a second portion connected to the other leading edge and projecting rearwardly therefrom. Each of the portions which project rearwardly from the first portion is outwardly inclined relative to the first portion so as to form a leaf-type spring which is compressible towards the first portion so as to be easily mounted in an opening in use.
