Abstract

A security system for a vestibule and, more specifically, a security vestibule is equipped with monitoring devices to monitor the presence of an intruder. The monitoring devices transmit signals to warning devices, such as a speaker which broadcasts an audible message as well as a siren and a flashing light which produce audible and visual signals, respectively, to attract attention exteriorly of the vestibule. The monitoring devices further transmit signals to deterrent devices which disturb or offend the perpetrator. The devices are of the type which disperse foul scents, dispense dyes to mark the perpetrator, disperse water at varying temperatures, and discharge electrical shock.

Claims

1. A security system for a vestibule providing sequentially increasing deterrence to the unauthorized entry thereof and encouraging the exit thereof, the vestibule having an interior door, an exterior door, two side walls, and an interior defined by the interior door, the exterior door, and the side walls, said security system comprising:

first sensing means disposed externally relative to the exterior door and providing for the detection of a person approaching the exterior door;

at least one primary deterrent means disposed externally relative to the exterior door and providing a change in an environmental condition proximate the exterior door and deterring the presence of a person thereby;

second sensing means disposed within the interior of the vestibule and providing for the detection of a person within the interior of the vestibule;

at least one final deterrent means disposed within the interior of the vestibule and providing a change in an environmental condition within the interior of the vestibule and encouraging the departure of a person therefrom through the exterior door; and

control means communicating with said first sensing means, said at least one primary deterrent means, said second sensing means, and said at least one final deterrent means and providing for the sequential operation of said first sensing means, said at least one primary deterrent means, said second sensing means, and said at least one final deterrent means in that order, whereby;

actuation of said first sensing means by the presence of a person outside of the vestibule causes said control means to activate said at least one primary deterrent means, and actuation of said second sensing means by the presence of a person within the vestibule causes said control means to activate said at least one final deterrent means.

2. The security system according to claim 1, wherein said first sensing means and said second sensing means are each motion detection devices.

3. The security system according to claim 1, wherein said first sensing means is a door switch which detects the movement of the exterior door from a closed position to an open position.

4. The security system according to claim 1, wherein said at least one primary deterrent means includes a speaker capable of producing a verbal warning message to fend off the perpetrator.

5. The security system according to claim 1, wherein said at least one primary deterrent means includes a siren capable of broadcasting exteriorly of the vestibule to attract attention exteriorly of the vestibule.

6. The security system according to claim 1, wherein said at least one primary deterrent means includes a light responsive to said actuation of said first sensing means, said light being produced exteriorly of the vestibule to attract attention exteriorly of the vestibule.

7. The security system according to claim 6, wherein said light is a flashing light.

8. The security system according to claim 6, wherein said light includes a wire cage thereover for the protection thereof against damage.

9. The security system according to claim 1, wherein said at least one primary deterrent means includes audible warning means and a sequentially activated means to dispense a foul scent and said change in the environmental condition proximate the exterior door is defined as an audible warning alerting the person to the subsequent activation of a dispersion of said foul scent, whereby said foul scent is offensive to the person'"'"'s sense of smell.

10. The security system according to claim 1, wherein said at least one primary deterrent means includes audible warning means and a sequentially activated means to discharge a dye and said change in the environmental condition proximate the exterior door is defined as an audible warning alerting the person to the subsequent activation of said discharge of said dye, whereby said dye marks the person, offending the person'"'"'s tactile senses and enabling the person to be identified remotely from the vestibule.

11. The security system according to claim 1, wherein said at least one final deterrent means includes a means to dispense water, said water being dispersable at varying temperatures, and said change in the environmental condition within the vestibule is defined as a dispersion of said water, whereby said dispersion of said water is offensive to the person'"'"'s tactile senses.

12. The security system according to claim 1, wherein said at least one final deterrent means includes a means to induce voltage upon the interior door, said voltage being inducible at varying levels, and said change in the environmental condition within the vestibule is defined as an induced voltage upon the interior door, whereby when the person engages in contact with the interior door, a current is discharged through the person, thus offending the person'"'"'s tactile senses.

13. The security system according to claim 12, wherein the interior door is insulated from ground by an insulation material to ensure that the person receives a maximum effect of said current being discharged.

14. The security system according to claim 1, wherein said control means includes timer means, whereby said first sensing means activates said timer means, said timer means begins to measure a time interval from said timer means activation, and after at least one predetermined time interval, said control means activates said at least one primary deterrent means, thus delaying an actuation of said at least one primary deterrent means, thereby decreasing a risk of inadvertent actuation of said at least one primary deterrent means.
