Abstract

The disclosed technology regards a reusable, non-pyrotechnic diversionary device having a housing assembly which receives and supports a pressure manifold, activation assembly, and a lighting assembly. The housing assembly includes a vessel, a main chassis, and a transparent lens. Positioned within the main chassis is a pressure manifold which supports a compressed gas source. A puncture pin is provided in the activation assembly, and aligned with the compressed gas source to facilitate puncture of the source. The disclosed technology further regards a reusable, non-pyrotechnic diversionary assembly having a housing assembly and a reloading tool. The reloading tool has an externally threaded inner body with an aperture at its distal end sized to receive the puncture pin, and an outer body sized and internally threaded to rotatably receive a portion of the inner body in its shaft, allowing the inner body to traverse through and from the shaft at its distal end. A threaded interface is provided on the outer body of the reloading tool to align with the first support structure of the pressure manifold. The inner body rotationally translates within the outer body to position the distal end of the inner body relative to the puncture pin and allow it to translate the puncture pin from an active position to a secured position.

First claim

The invention claimed is:

1. A reusable non-pyrotechnic diversionary assembly comprising:
a. a housing assembly supporting a pressure manifold and an activation assembly, wherein the pressure manifold comprises an aperture to support a compressed gas source within the housing assembly, and wherein the activation assembly comprises a puncture pin translatable between a secured position and an active position relative to the aperture of the pressure manifold;
b. wherein the housing assembly comprises a vessel which receives gas from the compressed gas source and upon achieving a state of over-pressure, ruptures to generate a concussive force; and
c. a reloading tool comprising an aperture at its distal end to receive the puncture pin when the reloading tool is received within the aperture of the pressure manifold, wherein the reloading tool translates the puncture pin from its active position to its secured position.

2. The reusable non-pyrotechnic diversionary assembly of claim 1 , wherein the reloading tool comprises an inner body and an outer body, the outer body being defined by a shaft in which the inner body is movably positioned, wherein the aperture of the reloading tool is positioned on a distal end of the inner body.

3. The reusable non-pyrotechnic diversionary assembly of claim 2 , wherein the inner body is externally threaded, and the shaft of the outer body is internally threaded, facilitating movement and positioning of the inner body relative to the outer body.

4. The reusable non-pyrotechnic diversionary assembly of claim 2 , wherein the aperture of the pressure manifold is internally threaded, and the outer body further has a threaded exterior surface to be received and removably secured at its distal end within the threaded aperture of the pressure manifold.

5. The reusable non-pyrotechnic diversionary assembly of claim 1 , wherein the housing assembly further comprises a main chassis, and wherein the vessel is removably secured to a first end of the main chassis.

6. The reusable non-pyrotechnic diversionary assembly of claim 1 , wherein the vessel comprises a perimeter wall having two or more propagation crevices extending from a pinnacle of a base of the vessel, along at least a portion of a length of the vessel.

7. The reusable non-pyrotechnic diversionary assembly of claim 6 , wherein the vessel material, shape, size or propagation crevice number, size or length, or any combination thereof, provide a certain time delay before rupture, a certain concussive force upon rupture, or a certain sound intensity of an acoustic impulse upon rupture, or any combination thereof, when used with the non-pyrotechnic diversionary assembly.

8. The reusable non-pyrotechnic diversionary assembly of claim 1 , wherein the activation assembly further includes a fuse train assembly comprising:
a. a fuse train housing;
b. a sear lever rotatably mounted on the fuse train housing at a first end between an active position and a secured position;
c. a puncture pin transfer bar rotatably aligned with the fuse train housing between an active position and a secured position, the transfer bar abutting at a first end the puncture pin; and
d. a main spring secured within the fuse train housing, and aligned with and abutting a second end of the puncture pin transfer bar, when the bar is in the active position;
wherein, when the reloading tool translates the puncture pin from the active position to the secured position, the sear lever rotates from its active position to its secured position, and the puncture pin transfer bar rotates from its active position to its secured position, and by such rotation, the second end of the puncture transfer bar reloads the main spring.

9. The reusable non-pyrotechnic diversionary assembly of claim 8 , wherein the activation assembly further comprises a trolley assembly, the trolley assembly including a spoon plunger, a spring-loaded front trolley slider, and a spring-loaded rear trolley slider, wherein the front trolley slider or the rear trolley slider, or both, have elongated receptacles along at least a central portion thereof to receive and secure a second end of the sear lever of the fuse train assembly when the trolley assembly is in a secured position, and translates the second end of the sear lever when the trolley assembly is in an active position; and wherein the sear lever rotates between its active position and its secured position.

10. The reusable non-pyrotechnic diversionary assembly of claim 9 , wherein the activation assembly further comprises a spoon lever; wherein the spoon lever is rotatably secured to the housing assembly, and is designed and configured to secure the trolley assembly in a secured position, and to allow release of the fuse train assembly to move the trolley assembly into its active position.

11. The reusable non-pyrotechnic diversionary assembly of claim 1 , wherein the housing further comprises a transparent lens and a high-intensity light.

12. A reusable non-pyrotechnic diversionary device comprising:
a. a housing assembly, the housing assembly comprising a vessel, a main chassis, and a transparent lens, wherein the vessel is removably secured to a first end of the main chassis and comprises a perimeter wall forming a vacuous area;
b. a pressure manifold supported within the housing assembly, the pressure manifold comprising structure to support a compressed gas source;
c. an activation assembly, the activation assembly comprising a puncture pin aligned with the compressed gas source support structure;
d. a lighting assembly comprising a high-intensity light source and an energy source; and
e. a reloading tool which translates the puncture pin from an active position to a secured position;
wherein the vessel receives gas from the compressed gas source and upon achieving a state of over-pressure, ruptures to generate a concussive force.

13. The reusable non-pyrotechnic diversionary device of claim 12 , wherein the vessel perimeter wall has two or more propagation crevices extending from a pinnacle of a base of the vessel, on the interior surface of the perimeter wall, along at least a portion of a length of the vessel.

14. The reusable non-pyrotechnic diversionary device of claim 13 , wherein the perimeter wall has a thickness at the pinnacle of the vessel base of between 1/32″ and ⅛″, and wherein the propagation crevices result in a reduced perimeter wall thickness of between ¼to ½ of the thickness of the perimeter wall at the pinnacle of the base.

15. The reusable non-pyrotechnic diversionary device of claim 12 , wherein the lighting assembly further comprises a pressure detection assembly and a light controlling circuitry to control operation of the lights, wherein the pressure detection assembly comprises a pressure sensor for detecting a pressure drop condition within the vacuous area of the vessel caused by rupture of the vessel, and communicates the condition to the light controlling circuitry.

16. A reusable non-pyrotechnic diversionary device comprising a housing which supports a vessel having a vacuous area, a light source, a compressed gas source, a puncture pin movable between an active position and a secured position, wherein in the active position the puncture pin is positioned to puncture a membrane of the compressed gas source, and a pressure sensor in communication with the light source to activate the light source when it senses a condition of pressure drop within the vacuous area of the vessel.
