Abstract
Abstract A chemical irritant spraying anti-burglary device is disclosed in which a chemical irritant such as tear gas is discharged into the area to be protected when an intruder opens a door or forces open a door to enter a private or unauthorized area with which the device is associated. The anti-burglary device employs a spring biased pressurized container for discharging a chemical irritant through a passageway and nozzle. A mechanical trigger for releaseably retaining a pressurized container in a cocked position and for releasing the pressurized container is described. In addition, a lock mechanism to place the mechanical trigger in a non-triggerable condition is also described.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
288 words
A chemical dispensing anti-burglar device comprising: a body member, a pressurized container, means for slidably supporting said container in said body member, a fluid passageway in said body member having an open entry section, means for discharging fluid from said container into said open entry section, a spring biasing said container toward said open entry section, means for releasably retaining said container in a cocked position away from said open entry section, said retaining means including a trigger element mounted for movement within said body member between an actuation position and a release position, said trigger element in the actuation position being in engagement with a surface of the container to retain the container in a cocked position, said trigger element in the release position allowing the container to be forced against the open entry section by the spring, whereby the means for discharging fluid causes discharge; means for locking said trigger element in engagement with said container, said locking means being mounted for movement within said body member between a locked position and a release position, said locking means in said locked position securing said trigger element in engagement with said surface of the container, and said locking means in its release position permitting the trigger element to move to its release position; and means external to the body member for releasably retaining the trigger element in its actuation position, said external retaining means including a latching plate mounted separate from the body member, the body member being movable between a first position in which the external retaining means retains the trigger element in its actuation position, and a second position in which the external retaining means allows the trigger element to move to its release position.
