An improved doorstop provides increased safety along with simplified operation over previous doorstops. The doorstop is adapted to be received in a floor mounted receptacle in close proximity to the door. The device includes a door contact member which pivots from a first position in contact with a fully closed door to a second position which permits the door to be opened a limited but finite distance. There is no need to remove the device from the floor receptacle to permit limited movement of the door, thus affording increased protection against forced entry. The improved doorstop is useful both on sliding doors as well as hinged doors. Several alternative embodiments of the improved doorstop are shown and described. When used with a hinged wooden door, the doorstop optionally includes the use of a rigid plate which may be affixed to the door to protect the door from damage by the device and to distribute force exerted against the door over a larger surface area.
An improved doorstop useful with a door to keep the door closed or alternatively to allow the door to be partially opened, said doorstop comprising:
A device adapted to be mounted on the floor in proximity to a door, said device comprising
A floor mounted safety device adapted to be inserted into a recess in the floor in proximity to a door, said device including
A device adapted to be mounted in a floor recess in proximity to a door, said device comprising a base member including a post to insertably engage the recess, and a planar portion serving to limit the distance that the post is insertable into the recess, a door contact means, and hinge means for pivotally joining said door contact means to said base member, said hinge means comprising an elongated semi-circular bead, and an elongated semi-circular groove to receive the semi-circular bead to permit said hinge means to pivot between a first position in contact with the door when said door is closed and a second position whereby limited but secure opening of the door is permitted.
