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.
A doorstop for selectively controlling the movement of a door, comprising a vertically extended shaft having a cylindrical lower portion slidably and rotatably received within a hole formed in a floor proximal a bottom edge of said door when in a closed position and a cross-member rigidly connected to said shaft above said cylindrical lower portion extending horizontally relative to said shaft, said cross-member having integrally connected thereto at least one end member projecting perpendicularly, substantially horizontally therefrom, wherein said door movement is discriminately controlled by selectively arranging said end members relative said door, said door movement substantially obstructed when said end member protrudes toward said door, said door movement controllably permitted when said end member protrudes away from said door wherein said door will contact said cross-member and pivot said cross-member about a vertical axis such that said door is arrested by substantially planer contact with said cross-member and said shaft, said cross-member extending horizontally a predetermined distance sufficient to ensure contact with said door over an area substantially wider than said shaft.
