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.
A door stop for temporary installation at the base of a door, for preventing an intruder from pushing the door open, said door stop comprising a generally wedge-shaped device having first and second ends, said first end of said wedge-shaped device having a narrow thickness dimension suitable for insertion under the door at a location remote from the door hinge, and said second end of said wedge-shaped device having a substantially larger thickness dimension, adjustment means operatively disposed adjacent said second end of said wedge-shaped device, said adjustment means enabling the effective height of said wedge-shaped device to be selectively increased by the user, such that a substantial upward force can be applied under the door, thus to effectively anchor said wedge-shaped device to the underside of the door, and an elongate, rigid member operatively associated with said wedge-shaped device, said elongate, rigid member having angled ends enabling it to extend in an angularly disposed, door-blocking relationship between the floor and a lower portion of the door, and means serving to attach a mid portion of said elongate, rigid member to said wedge-shaped device, to prevent displacement of said elongate, rigid member from a door-blocking relationship.
A door stop for temporary installation at the base of a door, for preventing an intruder from pushing the door open, said door stop comprising a generally wedge-shaped device utilized in an operative combination with an elongate, rigid member serving on occasion to block the opening of the door with which it is used, said wedge-shaped device having first and second ends, said first end of said wedge-shaped device having a narrow thickness dimension suitable for insertion under the door at a location remote from the door hinge, and said second end of said wedge-shaped device having a substantially larger thickness dimension, adjustment means operatively disposed adjacent said second end of said wedge-shaped device, said adjustment means enabling the effective height of said wedge-shaped device to be selectively increased by the user, such that a substantial upward force can be applied under the door, thus to establish an effective, binding relationship with a lower portion of the door, said elongate, rigid member having angled ends enabling it to extend in an angular attitude between the floor and a lower portion of the door in a door-blocking relationship, and means serving to anchor a mid portion of said elongate, rigid member to said wedge-shaped device, to prevent unintentional displacement of said elongate, rigid member from the door-blocking relationship.
