The disclosure relates to personal defense devices and more particularly pertains to a new personal defense device for projecting a lachrymator agent. The present invention discloses a pistol shaped device which can dispense a lachrymator agent onto a target, and which incorporates a flashlight and a fingerprint actuated trigger.
The prior art relates to personal defense devices, and in particular defense devices that project a lachrymator agent, such as pepper spray. Such prior art defense devices include pistol shaped devices which can dispense a lachrymator agent onto a target. What is lacking in the prior art is a personal defense device that is pistol shaped, incorporates a flashlight and a fingerprint actuated trigger, and which can dispense a lachrymator agent onto a target.
An embodiment of the disclosure meets the needs presented above by generally comprising an L-shaped housing, which defines a barrel and a grip. The grip extends from a first end of the barrel. A valve is positioned in the barrel proximate to the grip. A channel extends from the valve to a second end of the barrel. A cavity extends into the grip so that the cavity is in fluidic communication with the valve. The grip is configured to selectively engage a cannister, which contains a lachrymator agent, that is inserted into the cavity so that the cannister is removably engaged to the L-shaped housing. An outlet of the cannister is operationally engaged to the valve. A trigger is engaged to the L-shaped housing and is operationally engaged to the valve. The trigger is configured to be triggered to selectively actuate the valve. The lachrymator agent is dispensed under pressure from the cannister through the channel toward a target that is in substantial alignment with the barrel.
There has thus been outlined, rather broadly, the more important features of the disclosure in order that the detailed description thereof that follows may be better understood, and in order that the present contribution to the art may be better appreciated. There are additional features of the disclosure that will be described hereinafter and which will form the subject matter of the claims appended hereto.
The objects of the disclosure, along with the various features of novelty which characterize the disclosure, are pointed out with particularity in the claims annexed to and forming a part of this disclosure.
The disclosure will be better understood and objects other than those set forth above will become apparent when consideration is given to the following detailed description thereof. Such description makes reference to the annexed drawings wherein:
With reference now to the drawings, and in particular to
As best illustrated in
An outlet 32 of the cannister 28 is operationally engaged to the valve 20. A trigger 34 is engaged to the L-shaped housing 12 and is operationally engaged to the valve 20. The trigger 34 is configured to be triggered to selectively actuate the valve 20. The lachrymator agent 30 is dispensed under pressure from the cannister 28 through the channel 22 toward a target that is in substantial alignment with the barrel 14.
A battery 36 and a microprocessor 38 are positioned in the barrel 14. The microprocessor 38 is operationally engaged to the battery 36 and the valve 20. A trigger lock 40 is engaged to the L-shaped housing 12 and is operationally engaged to the microprocessor 38 and the trigger 34. The trigger lock 40 is positioned to selectively lock the trigger 34. Mechanisms for locking triggers are known to those skilled in the art of trigger locks and may comprise latches, linear actuators, and the like.
A fingerprint sensor 42 is engaged to the trigger 34 is operationally engaged to the microprocessor 38. The fingerprint sensor 42 is configured to authenticate a fingerprint of a user, positioning the fingerprint sensor 42 to signal the microprocessor 38 to actuate the trigger lock 40 to unlock the trigger 34.
A selector 44 is engaged to the barrel 14 and is operationally engaged to the microprocessor 38. The selector 44 is configured to be manipulated by the user to signal the microprocessor 38 to enable the fingerprint sensor 42 and to set the valve 20 to allow a respective flow rate from the cannister 28. For example, as shown in
An indicator 48 is engaged to the L-shaped housing 12 and is operationally engaged to the microprocessor 38. The indicator 48 may comprise a plurality of light emitting diodes 50, which is positioned on opposed faces 52 of the grip 16 and opposed sides 54 of the barrel 14, as shown in
A flow sensor 56 is operationally engaged to the valve 20 and is operationally engaged to the microprocessor 38. The flow sensor 56 is configured to measure a flow of the lachrymator agent 30 through the valve 20 and to communicate volumetric readings to the microprocessor 38. The microprocessor 38 is positioned to actuate the indicator 48 to display a volume of lachrymator agent 30 remaining in the cannister 28.
A flashlight 58 is engaged to the barrel 14 and is operationally engaged to the trigger 34. The trigger 34 is positioned to selectively actuate the flashlight 58 to project light past the second end 24 of the barrel 14. The flashlight 58 is configured to selectively illuminate the target. The flashlight 58 can be positioned on a top 64, a bottom 66 or a respective opposed side 54 of the barrel 14.
The personal defense device 10 also may comprise a magazine 60, which is configured for insertion of the cannister 28. The magazine 60 is selectively insertable into the cavity 26 so that the magazine 60 is removably engaged to the L-shaped housing 12. A release button 62 is engaged to the grip 16 and is selectively engageable to the magazine 60. The release button 62 is configured to be depressed to release the magazine 60 and the cannister 28 from the L-shaped housing 12.
In use, the cannister 28 is inserted into the magazine 60 and the magazine 60 then is inserted into the cavity 26. Should a user encounter a threat, the selector 44 is switched from the safe setting to either the medium setting or the high setting. The user then positions their finger on the trigger 34, whereupon the fingerprint sensor 42 authenticates the user's fingerprint to unlock the trigger 34. The user then pulls the trigger 34 and the lachrymator agent 30 is dispensed under pressure from the cannister 28 through the channel 22 toward the threat.
With respect to the above description then, it is to be realized that the optimum dimensional relationships for the parts of an embodiment enabled by the disclosure, to include variations in size, materials, shape, form, function and manner of operation, assembly and use, are deemed readily apparent and obvious to one skilled in the art, and all equivalent relationships to those illustrated in the drawings and described in the specification are intended to be encompassed by an embodiment of the disclosure.
Therefore, the foregoing is considered as illustrative only of the principles of the disclosure. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the disclosure to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of the disclosure. In this patent document, the word “comprising” is used in its non-limiting sense to mean that items following the word are included, but items not specifically mentioned are not excluded. A reference to an element by the indefinite article “a” does not exclude the possibility that more than one of the element is present, unless the context clearly requires that there be only one of the elements.
