Abstract

A sash lock mechanism of all-plastic construction incorporating a plastic detent spring arrangement having operating characteristics equal or superior those of conventional metallic springs while providing a more economical manufacture and assembly. The detent spring is of closed rectangular form, with inwardly bowed side elements positioned to act on opposite sides of a detent cam positioned between them, and connected at their ends by integral end and corner elements. The end and corner elements are closely confined against outward movement, causing the inwardly bowed side elements to be significantly more resistant to outward displacement by the detent cam when operating the lock. The arrangement provides a superior 'feel' and snap-action effect than expected from all-plastic detent mechanisms for the purposes intended.
