Abstract

An apparatus wherein an intruder may be restrained within a protected area and held captive therein until the proper authorities are summoned in order to deactivate the apparatus, and apprehend the thief, thereby preventing loss of property as well as loss or endangerment of human life.

Claims

1. Apparatus for restraining an intruder within a limited access area of a building, which comprises:

a. a walled enclosure forming a limited access area in combination with the floor and ceiling of the building and having one or more entryways contained therein;

b. an entry door positioned within each of the one or more entryways and having said entry door appearing to be nonstationary;

c. an electronic sensor positioned within the limited access area to detect the presence of an intruder within the limited access area; and

d. mechanical means for permanently positioning the one or more entry doors in a closed position responsive to the detection of the presence of the intruder by the electronic sensor so as to restrain the intruder within a limited access area.

2. The apparatus of claim 1 further comprising means for warning the intruder of his entrapment within the limited access area, said means being responsive to the permanent positioning of the entry door in a closed position.

3. The apparatus of claim 2 further comprising means for restraining the intruder from attempting to gain access to the exterior of the limited access area.

4. The apparatus of claim 3 wherein the means for restraining the intruder from attempting to gain access to the exterior of the limited access area are responsive to the intruder exerting force against the walls or entry door of the limited access area.

5. The apparatus of claim 4 wherein the means for restraining the intruder from attempting to gain access to the exterior of the limited access area comprise:

a. a gas supply containing a human activity restraining gas; and

b. means for introducing the restraining gas within the limited access area.

6. The apparatus of claim 5 in which the restraining gas is confined under pressure and the means for introducing the restraining gas within the limited access area comprise:

a. a gas delivery line, one end of which is connected to the gas supply and the other end thereof entering the limited access area; and

b. a gas distribution nozzle connected to the end of the gas delivery line exposed to the interior of the limited access area.

7. The apparatus of claim 4 wherein the means for restraining the intruder from attempting to gain access to the exterior of the limited access area comprise:

a. a network of electrical conductors formed within the walls aNd entry door exposed to the interior of the limited access area; and

b. an electrical energy supply connected to the network of electrical connectors.

8. The apparatus of claim 1 wherein one or more entry doors are (entry door is) normally opened (and) with each of the entry doors contained within the wall of the entryway adjacent to the entry and the means for permanently positioning each of the entry doors (door) in a closed position comprise:

a. a pneumatic piston having a piston base braced against the enclosure wall and the piston head in contact (contacting) with the entry door; and

b. a mechanical lock contained within the wall of the entryway opposite the wall containing the entry door, said lock engages the entry door as it is pneumatically driven across the entryway and holds (hold) the entry door permanently in a closed position.

9. The apparatus of claim 1 wherein the entryway is a circular revolving door and the walled enclosure is formed of the sides of the revolving door with the limited access area being defined by the floor, ceiling and sides of the revolving door and the point at which the sides of the revolving door contact the concave wall of the building.
