ABSTRACT:
A doorstop including an elongated shaft slidably and rotatably received within a receptacle seated in a floor proximal a door. The shaft extends vertically from the receptacle and has a cross-member integrally connected thereto and extending therefrom in opposing lateral directions such that the door, when opened toward the shaft, will contact the cross-member and rotate the cross-member into planar contact with the door. Thus, the movement of the door will be limited by the shaft and laterally extending cross-member. In a separate embodiment, end portions are integrally connected to the cross-member which project generally horizontally therefrom. When the end portions are facing or protruding toward the door, movement of the door from its closed position is completely obstructed. This embodiment functions as the original embodiment described above when the end portions are facing away from the door. A rigid plate may be connected to the door to protect the door from damage from the cross-member and shaft and, further, to distribute the force placed on the door over a larger surface area thereof.
