Abstract
A door security device for preventing opening of a door. A first device includes a bar that seats against a doorframe on opposite sides of the door and a clamp that clasps a door latch and applies a force to draw the bar against the doorframe while pulling the door latch toward the bar. The door cannot be opened away from the bar. A second device has a bar that seats against a doorframe at the floor with a two plates that extend beneath the door and around to opposite sides of the doorframe. Removable pins or other locks obstruct the plates from sliding along the bar. The bar is tall enough that the door cannot pass over the bar, thus obstructing the door from opening inwardly. A closer cover slides over a mechanical door closing mechanism to be used alone or with the other devices.
Claims7
An apparatus for preventing the opening of a swinging door that has a first door edge pivotably mounted to a first doorframe member, an opposing, second door edge removably attached to a second doorframe member, and a lower door edge spaced above a floor surface adjacent the lower door edge a predetermined distance, the apparatus comprising:
- (a) an elongated member;
- (b) a first plate mounted near a first end of the elongated member, the first plate having a first leg extending in a first direction from the elongated member, and a second leg extending transverse to the first leg;
- (c) a second plate mounted near a second end of the elongated member, the second plate having a first leg extending in the first direction, and a second leg extending transverse to the first direction and opposite the second leg of the first plate, wherein the first and second plates are configured for movement relative to one another;
- and
- (d) at least a first lock for preventing substantial relative movement of the first plate toward the second plate;
- wherein at least the elongated member has a height that is substantially greater than the predetermined distance between the lower door edge and the floor surface.
An apparatus mounted to a swinging door for preventing opening of the door, the door having a first door edge pivotably mounted to a first doorframe member, an opposing, second door edge removably attached to a second doorframe member, a door width defined as the distance between the first and second door edges, and a lower door edge spaced above a floor surface adjacent the lower door edge a predetermined distance, the apparatus comprising:
- (a) an elongated member having a length of about the door width, a first end seating adjacent an inside of the first door edge and a second end seating adjacent an inside of the second door edge;
- (b) a first plate extending beneath the door from a first end of the elongated member, the first plate extending to an outside of the first doorframe member;
- (c) a second plate extending beneath the door from a second end of the elongated member, the second plate extending to an outside of the first doorframe member, wherein the first and second plates are configured for movement relative to one another;
- and
- (d) at least a first lock preventing substantial movement of the first plate toward the second plate;
- wherein at least the elongated member has a height that is substantially greater than the predetermined distance between the lower door edge and the floor surface.
An apparatus for preventing the opening of a swinging door that has a first door edge pivotably mounted to a first doorframe member and an opposing, second door edge removably attached to a second doorframe member, and a lower door edge spaced above a floor surface adjacent the lower door edge a predetermined distance, the apparatus comprising:
- (a) a bar that is about as long as a distance from the first door edge to the second door edge;
- (b) a first plate rigidly mounted to a first collar that is slidably mounted along the bar near a first end of the bar, the first plate having a first leg extending in a first direction from the elongated member, and a second leg extending transverse to the first direction;
- (c) a second plate rigidly mounted to a second collar that is slidably mounted along the bar near a second end of the bar, the second plate having a first leg extending in the first direction, and a second leg extending transverse to the first direction and opposite the first plate;
- (d) a first pin extending into a first aperture in the bar between the first and second collars for preventing movement of the first collar toward the second collar beyond the first aperture;
- and
- (e) a second pin extending into a second aperture in the bar between the first and second collars for preventing movement of the second collar toward the first plate beyond the second aperture;
- wherein at least the bar has a height that is substantially greater than the predetermined distance between the lower door edge and the floor surface.
A method for preventing the opening of a swinging door that has a first door edge pivotably mounted to a first doorframe member, an opposing, second door edge removably attached to a second doorframe member, and a lower door edge spaced above a floor surface adjacent the lower door edge a predetermined distance, the method comprising:
- (a) seating a first end of an elongated member adjacent an inside of the first door edge and seating a second end of the elongated member adjacent an inside of the second door edge, whereby at least a portion of the elongated member extends higher than the lower door edge;
- (b) extending a leg of a first plate mounted near a first end of the elongated member under the door and around an outside of the first doorframe member;
- (c) extending a leg of a second plate mounted near a second end of the elongated member under the door and around an outside of the second doorframe member;
- and
- (d) restricting the first and second plates from moving substantially toward each other.
