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. 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.
Claims10
A doorstop for limiting the movement of a door from a closed position, comprising a vertically extended shaft having a cylindrical lower portion slidably and rotatably received within a hole formed in a floor and spaced a predetermined distance from a bottom edge of said door when in said closed position and a cross-member rigidly connected to said cylindrical shaft above said lower portion and extending laterally from said shaft in opposite directions, wherein movement of said door from said closed position will move said door in contact with said cross-member and pivot said cross-member about a vertical axis such that said door is arrested by substantially planar contact with said cross-member and said shaft.
