ABSTRACT:
A door stop for temporary installation at the base of a door, for preventing an intruder from pushing the door open. This novel door stop comprises a generally wedge-shaped device having first and second ends, with the first end of the wedge-shaped device having a narrow thickness dimension suitable for insertion under the door at a location remote from the door hinge. The second end of the wedge-shaped device has a substantially larger thickness dimension. A height adjustment device is operatively disposed on the second end of the wedge-shaped device, with this adjustment device enabling the effective height of the wedge-shaped device to be selectively increased by the user. In this way a substantial upward force can be applied under the door, thus to effectively anchor the wedge-shaped device to the underside of the door. An elongate, rigid member is operatively associated with the wedge-shaped device, with the elongate, rigid member having angled ends enabling it to extend in an angular, door-blocking relationship between the floor and a lower portion of the door. To prevent displacement of the elongate, rigid member from a door-blocking relationship, I utilize a component for attaching a mid portion of the elongate, rigid member to the wedge-shaped device. This component may for example be a tension spring.
