Abstract
Abstract A chemical dispensing anti-burglary device is described in which a chemical irritant such as tear gas is discharged into the area to be protected when an intruder opens a window or opens a door or enters an unauthorized area with which the device is associated. The anti-burglary device employs a spring biased pressurized container for discharging a chemical through a passageway and nozzle. A mechanical trigger for releasably retaining the pressurized container in a cocked position, an improved mechanical and electromechanical trigger to release the chemical, and a built in safety to deactivate the device which makes it virtually impossible to accidentally discharge the device are described.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
244 words
A chemical dispensing anti-burglary device for use with a pressurized container, the device comprising: a body member; means for slidably supporting said pressurized container in said body member; a fluid passageway extending through said body member having an entry section at one end thereof and a means for directing fluid discharge from the other end thereof; means for causing the discharge of fluid from said pressurized container into said entry section of said fluid passageway; a spring biasing said pressurized container in said body member and arranged to cause fluid discharge from said pressurized container upon movement of said slidably supported pressurized container when said pressurized container is released; means for releasably retaining said pressurized container in a cocked position; said retaining means including a trigger element; said trigger element being mounted for movement between an actuation position and a release position; said trigger element having a shaped portion for engaging with said pressurized container whereby movement of said spring urged pressurized container will force said trigger element to move to said release position; a trigger holding means mounted for movement between a holding position and a release position; said trigger holding means in said holding position adapted to hold said trigger in said actuation position to retain said pressurized container in said cocked position; said trigger holding means in said release position allowing said spring urged pressurized container to be forced against said entry section, whereby the means for discharging fluid causes discharge.
Claim 2
Dependent Claim
244 words
A chemical dispensing anti-burglary device for use with a pressurized container, the device comprising: a body member; means for slidably supporting said pressurized container in said body member; a fluid passageway extending through said body member having an entry section at one end thereof and a means for directing fluid discharge from the other end thereof; means for causing the discharge of fluid from said pressurized container into said entry section of said fluid passageway; a spring biasing said pressurized container in said body member and arranged to cause fluid discharge from said pressurized container upon movement of said slidably supported pressurized container when said pressurized container is released; means for releasably retaining said pressurized container in a cocked position; said retaining means including a trigger element; said trigger element being mounted for movement between an actuation position and a release position; said trigger element having a shaped portion for engaging with said pressurized container whereby movement of said spring urged pressurized container will force said trigger element to move to said release position; a trigger holding means mounted for movement between a holding position and a release position; said trigger holding means in said holding position adapted to hold said trigger in said actuation position to retain said pressurized container in said cocked position; said trigger holding means in said release position allowing said spring urged pressurized container to be forced against said entry section, whereby the means for discharging fluid causes discharge.
Claim 3
Dependent Claim
40 words
The chemical dispensing anti-burglar device of claim 1 wherein said pressurized container includes a projecting dispensing spout, said dispensing spout discharging fluid upon depression thereof, said entry section being funnel shaped for receiving said projecting dispensing spout on said container.
Claim 4
Dependent Claim
79 words
The chemical dispensing anti-burglar device of claim 1 wherein said pressurized container includes a projecting dispensing cap actuated to permit fluid discharge therethrough upon depression thereof, means for restricting movement of said projecting dispensing cap by said body member, an aperture in said body member in communication with said cap, said slidably supported pressurized container arranged to actuate said dispensing cap thereby discharging fluid from said pressurized container through said cap and aperture when said pressurized container is released.
Claim 5
Dependent Claim
47 words
The chemical dispensing anti-burglar device of claim 1 in which the pressurized container comprises a pierceable section, means to provide a seal between said pierceable section and said entry section, and means for puncturing said pierceable section as the container is released, whereby fluid may be discharged.
Claim 6
Dependent Claim
23 words
The chemical dispensing anti-burglar device of claim 4 in which said means for puncturing comprises a projecting spout depending from said body member.
Claim 7
Dependent Claim
24 words
The chemical dispensing anti-burglar device of claim 1 wherein said trigger element is mounted for rotation between said actuation position and said release position.
Claim 8
Dependent Claim
25 words
The chemical dispensing anti-burglar device of claim 1 wherein said trigger element is mounted for sliding movement between said actuation position and said release position.
Claim 9
Dependent Claim
19 words
The anti-burglar chemical dispensing device of claim 1 and a means for electromechanically retaining and releasing said trigger element.
Claim 10
Dependent Claim
78 words
The anti-burglar chemical dispensing device of claim 8 wherein said electromechanical retaining-releasing means of said trigger element comprises a solenoid latch lever for holding said trigger element in said actuation position, said solenoid lever being resiliently held in engagement with said trigger element to retain said pressurized container in said cocked position and a magnetic cored coil for moving said solenoid lever out of engagement with said trigger element whereby said trigger element moves to said release position.
Claim 11
Dependent Claim
104 words
The chemical dispensing anti-burglar device of claim 1 wherein said trigger element in said actuation position is in cammed engagement with a surface of said pressurized container, said cammed engagement arranged to move said trigger element from said actuation position to said release position, means for holding said trigger element in engagement with said pressurized container, said holding means mounted for movement between holding position and a release position, said holding means in said holding position securing said trigger element in engagement with surface of said pressurized container, said holding means in said release position permitting trigger element to move to its release position.
Claim 12
Dependent Claim
63 words
The anti-burglar chemical dispensing device of claim 1, wherein there is means for retaining said trigger element in said actuation position, said retaining means comprising of a fusible link mounted in engagement with said trigger element to retain said trigger element in a cocked position, said fusible link to release asid trigger element when an electric current is passed through said fusible link.
Claim 13
Dependent Claim
74 words
The anti-burglar device of claim 1 wherein there is a means to safely retain said trigger element, said retaining means including a pin, said pin being mounted for an insertion position and a removable position, said pin in said insertion position being mounted through a hole in said body member in a manner to prevent movement of said trigger element, said removable position having pin removed permitting movement of said trigger element when actuated.
