Abstract
A carabiner consisting of a C-shaped, elongated body member and an elongated closure member pivotally movable on one longitudinally terminal portion of the body member toward and away from a closing position in which both members jointly constitute a closed loop. The body portion is made from a tubular blank whose relatively heavy-walled end portions are of smaller diameter than the thinner-walled central portion. The longitudinally terminal portions of the body member are shaped by flattening the reduced end portions of the blank so that these terminal portions need not be machined to provide the necessary smooth internal contour of the closed carabiner.
Claims8
A carabiner comprising:
- (a) an elongated body member of tubular metallic material,
- (1) said body member being approximately C-shaped, having two bight portions connected by an approximately straight portion, and two longitudinally terminal portions respectively extending from said bight portions toward one another and defining a gap therebetween,
- (2) the wall thickness of said metallic material in said terminal portions being greater than in said bight and straight portions;
- (b) an elongated closure member having first and second longitudinal end portions, one of said end portions being pivotally secured to one of said terminal portions for arcuate movement of the other end portion toward and away from the other terminal portion;
- and
- (c) cooperating abutment means on said other end portion and said other terminal portion engageable for limiting said arcuate movement in a position of said closure member in which said closure member closes said gap,
- (1) the wall thickness of said metallic material in said one terminal portion being greater than the corresponding thickness in said other terminal portion.
