Abstract
A resilient clip or spring clip is disclosed which has a pair of jaw members and a generally U-shaped biasing member for connecting the jaws together and for biasing the jaws into a closed position. The biasing member has a pair of legs connected by a curvilinear central portion and a curvilinear support portion interior thereof. The central portion and support portion are connected by a bridge-like member, and define a channel therebetween. The sidewall of each jaw member has a closed sidewall extending along a substantial portion thereof and defines an arcuate surface. During actuation of the clip, the sidewall traverses through the channel in the biasing member, while the support portion defines and serves as a fulcrum for rotation of the jaws between the open and the closed positions, independently of any separate support member.
Claims14
A clip comprising:
- a pair of jaw members each having
- a first gripping end portion adapted to engage the corresponding first gripping end portion of the other jaw member for gripping an article or object therebetween;
- a second end portion defining a manually actuatable portion;
- and
- an intermediate portion having a closed sidewall extending along a substantial portion thereof and defining an arcuate inner surface;
- and
- a generally U-shaped resilient biasing member independently engageable with each of said jaw members and engageable with the pair of jaw members for resiliently urging said first end portions into engagement with each other, said biasing member having
- a pair of legs and a curvilinear central base portion integral with and joining said legs, said legs having a width adapted to pass through a space formed in said jaws and extending along said intermediate portions of said jaw members adjacent said closed sidewall, each of said legs extending respectively along an outer surface of said closed sidewall and being engageable with its respective jaw member at a position adjacent to said first gripping end portion with said curvilinear base portion extending between said jaw members, and
- a curvilinear support portion disposed internally of and connected to said biasing member adjacent said curvilinear base portion, said support portion and said base portion defining a curvilinear channel therebetween for receiving said closed sidewall of said intermediate portion of each said jaw member, said support portion engaging said arcuate surfaces of said intermediate portions of said jaws for defining a fulcrum therefor about an axis of rotation passing between said legs and within said curvilinear support portion,
- said jaw members pivoting about said axis of rotation along the surface of said fulcrum for separating said gripping end portions in response to pressure on said manually actuatable portions one toward the other and for moving said gripping end portions toward each other in response to the biasing force of said biasing member when said manually actuatable portions are released.
7 more elements
A clip comprising:
- a pair of jaw members;
- and
- a generally U-shaped fulcrum defining spring member independently engageable with each of said jaw members, said spring member defining a pair of legs connected by an integral arcuate central portion defining an arcuate recess between said legs, and an arcuate support portion interior of, spaced from, and connected to the central portion and being generally coaxial therewith, said central portion and said support portion defining a channel therebetween, said support portion defining a pair of opposed fulcrum support surfaces;
- each of said jaw members having a closed sidewall extending along a substantial portion thereof and defining an arcuate surface intermediate the ends thereof, said arcuate surface being engageable with said support portion of said spring member and being pivotal thereon, said legs of said spring member passing between said jaw members to engage outer surfaces of said closed sidewall adjacent one end thereof, the ends of said legs of said spring member being engageable with the outer surfaces of said closed sidewalls of said jaw members adjacent said first ends thereof for biasing said first ends toward each other to engage said first ends one with the other, said jaw members being operated by pressure applied to the opposite ends thereof for pivoting said jaw members about the axis of rotation defined by said arcuate support portion as passing through said arcuate recess within said spring member.

A clip comprising:
- a pair of jaw members each having a first gripping end portion, a second end portion, and a curvilinear intermediate portion having a closed sidewall extending along a substantial portion thereof;
- a one-piece generally U-shaped resilient biasing member engageable with the pair of jaw members for resiliently urging said first gripping end portions into engagement with each other;
- said biasing member including a pair of legs and a curvilinear central portion integral with and joining said legs, said curvilinear central portion and a portion of the legs of said biasing member being disposed between said jaw members and a portion of said legs extending through said jaws along said sidewalls to a point respectively along outer surfaces thereof, the free ends of said legs being engageable with said outer surfaces of said sidewalls at a position adjacent to said first end portions thereof, said U-shaped resilient biasing member further including a curvilinear support portion interior thereof and generally coaxial with the central portion thereof, the support portion being connected to the central portion and defining a curvilinear channel therebetween to receive the closed sidewall;
- the intermediate portions of said jaw members shaped to rotatably engage the surface of said curvilinear support portion of said biasing member which defines a fulcrum therefor about an axis of rotation passing between said leg portions and within said curvilinear support portion of said biasing member, said jaw members being pivotal about said axis of rotation along the surface of said fulcrum defining curvilinear support portion in response to pressure applied to said second end portions, one toward the other for separating said first end portions and for effecting movement of said first end portions toward each other in response to the force of said biasing member when said second end portions are released.
