ABSTRACT:
A mostly automatic device designed to hold open a common interior or exterior door simply by swinging the door until it strikes a small spring-loaded lever which moves in a linear mode, allowing the door to pass by said lever and to contact a larger lever with its own spring which is required to securely hold the door's edge, said small lever also assisting in holding the door trapped within the confines of both levers until such time as the door is pulled forward, this action releasing it from the pressure of the larger lever, and at the same moment causing the smaller lever to rotate and permit the door to pass by it, thus allowing the door to be freed of its formerly confined condition.
