Abstract

Integral synthetic plastic spring clip used for attaching identification badges and the like to garments. The clip comprises a pair of lever arms interconnected at their outer ends by a spring-forming web. The other ends of the arms terminate in mating jaw portions. The lever arms include interengageable detent portions adapted to form a fulcrum for pivotal movement of said lever arms for the opening and closing of the jaw portions of the clip. The interengagement of said detents also biases said web so that it acts as a spring in compression to urge the jaw portions of the clip together for clamping engagement with a material disposed between said jaws.

Claims

1. Spring clip integrally molded of synthetic plastic material comprising a pair of lever arms adapted for pivotable movement about a fulcrum provided by interengageable post and socket detents formed on opposed inner surface portions of a pair of bosses, each boss extending from opposite side edges of each arm, the axis of engagement of said post and socket detents extending transversely of the direction of pivotable movement of said lever arms, the inner end portions of said lever arms being in the form of jaws which by manipulation of the outer ends of said lever arms are movable toward and away from each other for selectively clamping and releasing a material disposed therebetween, a resilient spring forming web of synthetic plastic material disposed between the outer end portions of said lever arms, the spring web being generally U-shaped and of substantially lesser thickness than said arm portions of the clip and with the outer end portions of the spring web extending from the outer ends of said lever arms and having a curved central portion disposed toward said detents, said spring web being in unstressed condition when the detents are not engaged and being energized to bias said jaws toward their mutual clamping relation when said post and socket detents are engaged, whereby said jaws are urged closed by said spring web and are opened by compressing said spring by squeezing together the outer end portions of said lever arms, said clip being molded with said bosses spaced apart with their inner surfaces generally co-planar and said spring web in its relaxed condition, said mating post and socket detents adapted to snap-fit into engagement when said lever arms are squeezed together after removal of the clip from the mold, said post and socket detents serving as the pivot fulcrum of the lever arms of said clip.

2. Spring clip, as set forth in claim 1, in which said post and socket include camming means by which squeezing together automatically of said lever arms will cause the post and socket to snap fit together thereby placing the spring web in compression.

3. Spring clip, as set forth in claim 1, in which a stud for supporting a badge extends outwardly of the outer surface of one of said lever arms and include an enlarged head portion adapted to interfit with a mating female portion of a post and socket snap fastener combination for supporting an identity badge or the like.
