Abstract
A fluid dispensing anti-burglar device is disclosed in which a chemical irritant such as tear gas is discharged into the area to be protected when an intruder forces entry into the area to be protected with which the device is associated. The anti-burglar device employs electrical elements for causing the release of the irritant gas and includes provisions for time delayed release of the chemical irritant.
Claims27
A fluid dispensing anti-burglar device for use with a pressurized container, the device comprising:
- (a) a body member;
- (b) means for supporting said pressurized container in said body member, wherein said pressurized container has a fluid-dispensing element adapted to release fluid under pressure from said pressurized container when actuated;
- (c) a passageway in said body member having an entry section at one end thereof;
- (d) dispensing element-actuating means mounted in said body member and adapted to engage and actuate said fluid-dispensing element;
- (e) spring means biased to force said fluid-dispensing element and said dispensing element-actuating means into engagement with each other, thereby causing said fluid-dispensing element to be actuated;
- (f) trigger means adapted to releasably retain said spring means in a cocked position in which said fluid-dispensing element and said dispensing element-actuating means are separated from each other;
- (g) trigger-actuating means associated with said trigger to actuate said trigger upon the application of an electric current to said trigger-actuating means, whereby said spring is released from its cocked position causing said fluid-dispensing element to be actuated, and fluid under pressure is released from said container to pass through said passageway;
- (h) delay means for causing the delay of the application of electric current to said trigger-actuating means after electric current is applied to said device, thereby permitting the removal of said electric current if the electric current is accidentally applied to the device;
- (i) and a circuit board containing the trigger-actuating means and the delay means mounted within said body member.
