Carabiner

Abstract

This product is a carabiner equipped with an openable and closable gate (a track-like (or playground-shaped) annular section shown in the left side view). The gate is normally biased in the closing direction by a spring or the like and maintains a closed state. When an external force is applied to the gate, it opens, allowing a key ring or the like to be passed through the opening. The reference diagram is a perspective view of the carabiner with a key ring passed through it.
