Personal defense device and method

Claim 3

A personal defense device adapted to be attached to the user's person, comprising: a. a hollow housing having a size, configuration and appearance in simulation of a telephone pager; b. multiple canisters received on the interior of said housing in side-by-side relation, each of said canisters including a dispensing nozzle adapted for activation upon the inward movement thereof, and each of said canisters containing like combinations of compressed gas and incapacitating chemical adapted to be dispensed as a spray; and c. a manifold unit movably deployed in said housing, with a single outlet orifice about 0.035 to 0.065" in diameter communicating with the atmosphere, with multiple inlet orifices about 0.075 to 0.11" in diameter individually engaging respective dispensing nozzles of said canisters, with an interior manifold passage about 0.11 to 0.13" in diameter, and with button means for moving said manifold unit towards said canisters to activate said nozzles; whereby manual pressure on said button means causes simultaneous inward articulation of each of said nozzles in said canisters, thereby simultaneously dispensing a combination of compressed gas and incapacitating chemical from each canister in an integrated flow through said manifold unit and into the atmosphere through said outlet orifice in a multiple dose spray having a spray range of at least 8 to 10 feet.

Claim 4

A personal defense device adapted to be attached to the user's person, comprising: a. a hollow housing having a size, configuration and appearance in simulation of a telephone pager; b. multiple canisters received on the interior of said housing in side-by-side relation, each of said canisters including a dispensing nozzle adapted for activation upon the inward movement thereof, and each of said canisters containing like combinations of compressed gas and incapacitating chemical adapted to be dispensed as a spray; and c. a manifold unit movably deployed in said housing, with a single outlet orifice about 0.035 to 0.065" in diameter communicating with the atmosphere, with multiple inlet orifices about 0.075 to 0.11" in diameter individually engaging respective dispensing nozzles of said canisters, with an interior manifold passage about 0.11 to 0.13" in diameter, and with button means for moving said manifold unit towards said canisters to activate said nozzles; whereby manual pressure on said button means causes simultaneous inward articulation of each of said nozzles in said canisters, thereby simultaneously dispensing a combination of compressed gas and incapacitating chemical from each canister in an integrated flow through said manifold unit and into the atmosphere through said outlet orifice in a multiple dose spray having a spray range of at least 8 to 10 feet.

Claim 5

The device of claim 2 wherein said canisters of compressed gas contain oleoresin capsicum.

Claim 6

The device of claim 2 wherein the interior walls of said housing are provided with guide means for stabilizing the movement of said manifold unit towards said compressed gas containers, to equilize the discharge of compressed gas from said canisters.

Claim 7

The device of claim 4 wherein said guide means comprise rails on the interior walls of said housing, which register with slots in adjacent surfaces of said manifold unit.

Claim 8

The device of claim 2 wherein said multiple canisters comprise two containers carrying about 1/2 ounce each of incapacitating spray material and wherein the said manifold unit has inlet orifices about 0.09 to 0.11" in diameter, an outlet orifice about 0.055 to 0.065" in diameter, and an interior manifold passage about 0.11 to 0.13" in diameter.

Claim 9

The device of claim 2 wherein said multiple canisters comprise three containers carrying about 1/4 ounce each of incapacitating spray material and wherein the said manifold unit has inlet orifices about 0.075 to 0.085" in diameter, an outlet orifice about 0.035 to 0.045" in diameter, and an interior manifold passage about 0.11 to 0.13" in diameter.

Claim 10

The device of claim 2 further comprising an electronic alarm unit stored on the interior of said housing and also battery means positioned therein to provide power for said alarm unit.

Claim 11

The device of claim 1 further comprising a safety slide carried by said housing and manually shiftable relative to the housing to and from a first position wherein said manifold unit is locked in an inoperative condition and a second position wherein said manifold unit may be moved by manual pressure on said button means to dispense compressed gas from said canisters.
