Personal defense spray device
A self defense spray device comprising a spray unit having a spray canister with an irritant spray, a nozzle operable to release the irritant spray, and a first connector attached to the spray canister. The device further includes a holder having a second connector adapted to releasably engage the first connector to releasably connect the spray unit to the holder, and a safety mechanism that prevents the nozzle from releasing the spray when the spray unit is connected to the holder, thus disarming the device. Once the spray unit is removed from the holder, the safety no longer blocks the nozzle thus arming the device.
1. A self defense spray device comprising:
a spray subassembly and a holder wherein the spray subassembly and the holder are separate units that are adapted to be releasably connected to each other;
the spray subassembly comprising a spray canister containing a pressurized irritant spray and having a valve therein capable of being actuated to release the irritant spray, a nozzle in fluid communication with the valve and operable to actuate the valve to release the irritant spray via the nozzle, and a first connector attached to the spray canister, the first connector having a keeper portion, wherein the spray subassembly is functional as a distinct unit for discharging the irritant spray;
the holder comprising a second connector having a latch member adapted to releasably engage with the keeper portion of the first connector to releasably connect the spray subassembly to the holder, and a safety mechanism that is adapted to cooperate with the spray subassembly to interfere with the actuation of the valve by the nozzle;
wherein when the spray subassembly is connected to the holder, the safety mechanism interferes with the actuation of the valve by the nozzle to prevent a discharge of the irritant spray at any time while the spray subassembly remains connected to the holder; and
wherein when the spray subassembly is separated from the holder, the safety mechanism does not interfere with the actuation of the valve by the nozzle to enable a discharge of irritant spray from the spray subassembly.
2. The device of claim 1 further including a spray housing adapted to receive at least a portion of the spray canister and wherein the first connector is a part of the spray housing.
3. The device of claim 2 wherein the holder comprises a holder housing adapted to receive the first connector.
4. The device of claim 3 wherein the first connector comprises a horizontal member extending from the spray housing and includes the keeper portion, and wherein the latch member is moveable by the user to selectively engage and disengage the keeper portion to effect the latching and unlatching of the spray subassembly to the holder.
5. The device of claim 4 wherein the latch member is moveable in a sideways direction and is adapted to engage and disengage the keeper portion as a result of the latch member being so moved.
6. The device of claim 5 wherein the latch member is biased towards a position in which the latch member engages the keeper portion.
7. The device of claim 6 wherein the latch member includes a cam following element and the keeper portion includes a cam element that cooperates with the cam following element to displace the latch member against the bias as the horizontal member is brought into initial contact with the latch member, and which releases the cam following element once the keeper portion moves beyond the cam following element such that the latch member returns to the position in which it engages the keeper portion.
8. The device of claim 7 wherein the holder further includes a connector cover moveable between a first position in which it allows access by a user to the latch member, and a second position in which it prevents access by the user to the latch member, thereby minimizing accidental disengagement of the spray subassembly from the holder.
9. The device of claim 8 wherein the safety mechanism comprises at least one projection that interferes with the movement of the nozzle only when the spray subassembly is connected to the holder to prevent the nozzle from actuating the valve.
10. The device of claim 1 wherein the safety mechanism comprises at least one projection that interferes with the movement of the nozzle only when the spray subassembly is connected to the holder to prevent the nozzle from actuating the valve.
11. The device of claim 10 wherein the holder comprises a holder housing adapted to receive the first connector, the at least one projection extends from the holder housing, and the nozzle includes at least one recess adapted to receive the at least one projection when the spray subassembly is connected to the holder.
12. The device of claim 11 further including a spray housing adapted to receive at least a portion of the spray canister and wherein the first connector is a part of the spray housing.
13. The device of claim 12 wherein the first connector comprises a horizontal member extending from the spray housing and includes a keeper portion, and the second connector comprises a latch member that is moveable by the user to selectively engage and disengage the keeper portion to effect the latching and unlatching of the spray subassembly to the holder.
14. The device of claim 13 wherein the latch member is moveable in a sideways direction and is adapted to engage and disengage the keeper portion as a result of the latch member being so moved.
15. The device of claim 14 wherein the latch member is biased towards a position in which the latch member engages the keeper portion.
16. The device of claim 15 wherein the latch member includes a cam following element and the keeper portion includes a cam element that cooperates with the cam following element to displace the latch member against the bias as the horizontal member is brought into initial contact with the latch member, and which releases the cam following element once the keeper portion moves beyond the cam following element such that the latch member returns to the position in which it engages the keeper portion.
17. The device of claim 16 wherein the holder further includes a connector cover moveable between a first position in which it allows access by a user to the latch member, and a second position in which it prevents access by the user to the latch member, thereby minimizing accidental disengagement of the spray subassembly from the holder.
18. The apparatus of claim 1 further including a light source mounted in the spray subassembly, a first source of electrical power connected to the light source, a first electrical circuit connecting the first source of power to the light source, a first electrical switch connected to the first electrical circuit and configured to complete the first electrical circuit when the spray subassembly is disconnected from the holder thereby providing illumination, and to break the first electrical circuit when the spray subassembly is connected to the holder thereby terminating illumination.
19. The apparatus of claim 1 further including an electrical sound generator mounted on the holder, a second source of electrical power connected to the sound generator, a second electrical circuit connecting the second source of power to the sound generator, a second electrical switch connected to the second electrical circuit and configured to complete the second electrical circuit when the spray subassembly is disconnected from the holder thereby providing an audible alarm, and to break the second electrical circuit when the spray subassembly is connected to the holder thereby terminating the audible alarm.
