Abstract
In some aspects, the invention features a door stop. In some embodiments, the door stop can be used to lock doors open. The door stop can include a base having first and second contact surfaces. The base can be positionable in an open position. In the open position, the first contact surface can contact a door jamb, a first hinge plate, or both. In the open position, the second contact surface can contact a hinged edge of a door, a second hinge plate, or both. The base can include a third contact surface. The third contact surface can be configured to contact a frame stop when the base is positioned in the open position. The third contact surface can be generally perpendicular to the first contact surface.
