Abstract
The present invention relates to a night stop that includes a housing, tumbler, spring, and a right arcuate nest, located on the inside bottom surface of the housing, used for maintaining the bottom rounded portion of the spring. The tumbler of the present invention has a top rear surface that is used as a button for activating the tumbler. In addition, the tumbler of the present invention has a concave rear bottom portion that contacts a stopping member when the tumbler is in an activated position. The spring of the present invention is partially housed inside of a bored cavity located on the tumbler. The bottom rounded portion of the spring is maintained in an arcuate nesting area when the tumbler is deactivated. When the tumbler is activated the bottom rounded spring portion traverses over and across a divide point into a right recession area.
