Abstract
Disclosed is a plastic fastener which comprises one or more protective frames having a profile suitable for substantially intimate insertion into matched openings formed in a given basal object and as many fixing legs formed within the empty spaces enclosed with the protective frames and provided with engaging claws for fast engagement with the edges of the openings in the basal objects. When the fastener is attached to the basal object by the cooperation of the fixing legs and their respective protective frames, the protective frames bring about a reinforcing effect and add greatly to the fastness of the engagement between the fastener and the basal object.
Claims5
A plastic fastener adapted for insertion through one or a pair of openings in a basal object and comprising in combination:
- a support plate;
- a pair of spaced apart fixing legs integrally molded with said support plate so as to protrude from one surface of said support plate, each said fixing leg being provided on the free end thereof with a laterally protruding engaging claw;
- a pair of protecting frames provided integrally on said support plate, each frame having frame side portions extending from the support plate and a frame end portion connecting the frame side portions at the free ends thereof embracing the two sides and the free end of one of said fixing legs;
- said engaging claws protruding from the open surfaces of said protective frames;
- said protective frames having the frame end portions entirely spaced from each other at the free ends of the frames adapting the same for insertion through one or a pair of openings in a given basal object and the respective fixing legs being sufficiently elastic to yield during insertion, and thereafter said laterally protruding engaging claws grippingly engaging respective adjacent edges of said opening;
- said protective frames preventing said engaging claws from releasing their engagement with the adjacent edges of the opening due to any external forces applied to said fastener.
