Reusable Paint Ball Grenade, Reloadable With Standard .68 Caliber Paint Balls

None.

This invention relates to marking devices, specifically to an improved recreational Paint Ball grenade that may be reloaded with 0.68 caliber paint balls, and reused.

A Paint Ball grenade is a device by which quantities of paint are delivered and dispensed to a location remote from the user with the intent of eliminating an opponent from a recreational Paint Ball game. The generally accepted rules of Paint Ball preclude any participant from continuing to play subsequent to receiving a paint marking. Paint Ball is a relatively immature sport that simulates combat situations in a non-lethal environment. Other than the fundamental armament, the Paint Ball Gun, few complex devices have been developed.

Heretofore, Paint Ball grenades have been relatively crude devices, limited in design to a single usage. One such system, shown in U.S. Pat. No. 4,932,672 is a grenade comprised of a length of rubberized material similar to a bicycle tire innertube, filled to excess capacity with paint, sealed on its ends, folded in the center, reinformed by a net wrap, and fitted with an electrical connector cap over the adjacent sealed ends. An automotive type cotter pin extends through the electrical connector, and with its associated pull ring, simulates the traditional grenade pin present in functioning military grenades. Instructions for this device require the user to "pull pin, remove cap," and note that the grenade "will go off on impact". Additional instructions suggest user shake grenade "before game use to dissolve sediment." The contents are dispensed with a flailing action in the immediate vicinity of its impact. Subsequent to this one time use, the player must retrieve, remove, and dispose of the rubber paint casing, as well as the cap and cotter pin which comprise the grenade.

Accordingly, several objects and advantages of my invention are as follows: it provides superior size, weight and aerodynamic characteristics from the prior art; it has a bail by which it may be secured and transported prior to use during a game; it may be stored unloaded in a wide variety of environments, unaffected by extreme heat or cold; it has a predetermined and predictable dispersal pattern; it is easily refillable and reusable in subsequent games; it cannot be reloaded and reused during a Paint Ball game by anyone not possessing the appropriate grenade pin, thereby reducing the possibility of being claimed and used against its owner; it has multiple safety interlocks to minimize inadvertent actuation, and physical restraints to preclude injury in the event of catastrophic failure; it has an adjustable actuator; may be easily uploaded to change or blend color combinations at will; and it contains an internal environmentally friendly renewable (resettable) power source facilitating its application as a mine-like device actuated by any of a variety of mechanical triggering mechanisms.

Still further objects and advantages will become apparent from a consideration of the ensuing description and accompanying drawings.

Contained with center post thru-hole for actuator mechanism (30) of center post (20) is Actuator adjusting screw (32), actuator spring (34), actuator washer (36), and actuator ball (38). Power spring retaining pin (44) is installed thru retaining pin installation hole (45) of upper housing (90) and captures upper washer (46), power spring guard (48), power spring (50), and lower washer (46) above the core (118) as center post (20) passes thru core thru-hole for center post (119).

As a Prepositioned Mine--A chord or wire may be secured to the Pull ring (56) so that the mechanical displacement of the pin (54) by pulling the wire would cause immediate functioning of the device.

As a Dispersal Device for Chemical or Biological Agents--The object of my invention may also be employed as a dispersal device for chemical or biological agents by employing 0.68 or smaller diameter capsules that have been filled with one or more of a variety of chemical agents.

Operation of my grenade is presented in five sequential procedures: inspection prior to use; resetting the power spring (50); uploading paint balls (126); deployment; and adjusting actuator sensitivity. Prior to use, all parts must be inspected to assure they are fully functional and free of dried paint. User should assure the free movement of safety interlock handles (64). Pin (54) should be available and undamaged. Actuator mechanism should be operational with adjusting screw (32) installed and actuator ball (38) clean and properly seated. Loading door (100) should be fully operational, free of accumulated paint with hinge (102) operational. Loading door safety cam (99) should engage and advance safety interlock handle (64). Loading door safety interlock pendulum should be free of dried paint, operating freely with safety interlock stop (104) operational.

Resetting power spring (50) is accomplished by grasping finger guard (96) with palm of hand while applying minimal force upon one or more safety interlock handles (64). Rotate bail (84) in either direction until transverse to longitudinal axis of grenade. Invert grenade and press center post spherical top (21) on hard surface. Force center post (20) into grenade until perimeter of center post spherical top (21) is flush with top of cap (72). As power spring (50) is compressed actuator ball (38) will engage cap neck-down actuator interface (80). One or more safety interlock handles (64) will engage center post notch for safety interlock pin (26). Insert pin (54) into cap thru-hole for pin (76) with the plane created by the pull ring (56) perpendicular to the grenade's longitudinal axis. Once inserted, rotate pin (54) until plane created by pull ring (56) is positioned parallel to longitudinal axis of grenade.

Load paint balls (126) after power spring (50) has been reset. Pin (54) and associated pull ring (56) must be rotated until plane created by pull ring (56) is perpendicular to longitudinal axis of grenade. Grenade length will increase slightly as the pin (54) cam (58) rotates to the load/pull position. Growth results in distance between top surface of liner (138) and the bottom surface of ball cutter retainer (121) increasing sufficiently to allow insertion of paint ball (126). Grasp finger guard with palm of hand, center post base (22) closest to loader's body, loading door (100) away from palm. Using loading door finger tab (105) open loading door (100) pivoting upward toward top of grenade. Loading door (100) will snap open as loading door closure tabs (97) disengage from the finger guard (96). As loading door (100) opens, loading door safety interlock pendulum covers opening and minimizes possibility of crush injury should other safety devices catastrophically fail. When loading door (100) reaches full travel, safety interlock handle (64) engages center post notch for safety interlock pin (26). Once loading door (100) is fully opened, loading door safety interlock pendulum (103) must be pivoted upward into loading door (100). Paint balls (126) may now be inserted into the opening created by loading door (100). When complete, loading door (100) should be closed until loading door safety interlock pendulum covers opening in finger guard (96), to preclude inadvertant insertion of fingers into paint ball (126) area. Pin (54) pull ring (56) should then be rotated 90 degrees (in either direction) causing pin (54) cam (58) to interlock with the spring loaded center post (20) precluding the inadvertent extraction of pin (54) while causing distance between the upper surface of the lower housing (128) liner (138) and the bottom surface of the ball cutter retainer (121) to be decreased sufficiently for paint balls (126) to align themselves in liner paint ball race (140). Alignment of paint balls (126) in liner paint ball race (140) simultaneously positions paint balls within functional proximity of ball cutter (116). Loading door should now be closed and snapped shut as loading door closure tabs (97) engage opening for loading door (100) in finger guard (96).

Deployment--grenade is typically worn onto playing field attached by bail (84) to various types of snap hooks on vest or belt. Deployment procedure involves removing grenade from vest or belt, grasping grenade with finger guard (96) in palm of hand while simultaneously pressing (engaging) one or more safety interlock handles (64). Rotate pin (56) pull ring (58) until plane created by pull ring (56) is perpendicular to the longitudinal axis of grenade. While maintaining engagement of one or more safety interlock handles, remove pin (56). As grenade travels downrange, spring loaded safety interlock handles(64) previously depressed will retract (disengage). Power spring (50) will be restrained by engagement of actuator ball (38) against cap neck-down actuator interface (80). Upon adequate jarring impact, the relationship between the two grenade halves, specifically those components attached to and including the upper housing (90) and those components attached to and including the lower housing (128) and center post (20) will change slightly. The distortion occurring at the minimal clearances that exist between center post (20) and core thru-hole for center post (119) and cap bearing surface for center post (82). Such distortion when combined with jarring action, causes the potential of compressed power spring (50) to overcome resistance created by actuator spring (34) causing spring loaded actuator ball (38) to retract into center post (20) thus allowing power spring (50) to expand. Expansion of power spring (50) causes liner (138) to close with ball cutter retainer 121. Continued compression of the paint balls (126) will cause ball cutter retainer (121) to deflect into finger guard void for ball cutter retainer displacement (108), exposing paint balls (126) to ball cutters (116) thus breaching the integrity of the paint ball (126) membrane. Orientation of paint balls (126) within the liner paint ball race (140) is irrelevant due to the total quantity and locations of the ball cutters (116). Simultaneous membrane breach reduces total potential required from power spring (50) to accomplish mission while minimizing potential delta in necessary crushing force created by inconsistencies in paint ball membranes. Continued expansion of power spring causes pressurization of released paint between liner (138), ball cutter retainer (121), and interior of finger guard (96). Acting as a non-positive displacement pump, continued closure of the liner (138) and ball cutter retainer (121) forces paint through finger guard paint dispersal ports (98), which have been designed to maximize the tradeoff between volume and dispersal distance. Core (118) acts as the upper housing (90) component terminus for the power spring while increasing the volumetric paint dispersal efficiency of the device. Alignment between the upper housing (90) and associated parts, and lower housing (128) and center post (20) and their collective associated pans, is provided by liner thru-hole for center post (142), core thru-hole for center post (119) and cap bearing surface for center post. Potential misalignment between the two housing halves requires clearance exist between core (118) and liner (138). This clearance allows pressurized paint to pass into the base of the liner (138), potentially preventing the complete closure of liner (138) and ball cutter retainer (121). Blow-by paint, accumulating in the base of liner (138) may drain into lower housing (128) through liner drain holes (144) and out of lower housing (128) through lower housing drain holes (136). Upon complete compression of paint balls (126) by the power spring (50), between liner paint ball race (140) and ball cutter retainer (121), the residual membranes collect in the liner paint ball race (140), thus maximizing the potential of the of the device. Subsequent to deployment and functioning, the power spring (50) can be reset and residual paint ball (126) membranes removed with the assistance of a small stick through the loading door (100), by rotating the lower housing (128) and associated parts in relationship to the upper housing (90) and associated pans. Care should be taken to assure one or more of the safety interlock handles (64) are completely engage before introducing any foreign device into the paint ball (126) area.

Adjust actuator setting--actuation sensitivity adjustments may only be done when the device is in the unloaded/functioned configuration. Procedure is accomplished by manipulation of the actuator adjusting screw (32) in order to increase or decrease the compression on actuator spring (34), thus increasing or decreasing the force necessary to cause the actuator ball (38) to retract into the center post (20), thus allowing the power spring (50) to function the device. Permanent actuator adjustment markings (40) on the center post (20) indicate direction actuator adjusting screw (32) must be turned to increase or decrease the sensitivity of the actuator mechanism.

As a Prepositioned mine--the object of my invention may also be used as a prepositioned mine by screwing actuator adjustor screw (32) counterclockwise until the force placed upon actuator spring (34) is inadequate to preclude the power spring (50) from causing the device to function. By eliminating the actuator ball's (38) resistance, the loaded the device, when secured appropriatelly to produce the desired dispersal effects, will function when the pin (54) is removed. To do this remotely, in person, or with trip wire, the pin (54) pull ring's (56) plane must be perpendicular to the longitudinal axis of the grenade. A chord or wire may be secured to the pull ring (56) so that the mechanical displacement of the pin (54) by pulling the wire would cause immediate functioning of the device.

Dispersal device for chemical agents--the aforementioned paint ball grenade may be employed to deliver and disperse a variety of flammable or chemical agents by law enforcement or government military organizations. Any 0.68 or smaller capsule may be loaded into the device for remote deployment without the complications of explosive timing devices typically necessary in the dispersal of chemical substances. Conceivably the device could be utilized for the deployment of leathal and nonleathal binary chemical and biological weapons currently under development. The advantage to this design is its simplicity and lack of expensive mechanical fuze-like timing mechanism that are highly suseptable to the corrosive characteristics of many of todays chemical munitions.

Accordingly, it can be seen that my invention provides numerous advantages over the prior art. They include but may not be limited to: its superior size, weight and aerodynamic characteristics; its incorporation of a bail by which it may be secured and transported prior to deployment; it may be stored in a wide variety of environments, unaffected by extreme heat or cold until after it is uploaded; it has a predetermined and predictable dispersal pattern; it is easily refillable and reusable; it cannot be reloaded and reused during a Paint Ball game by anyone not possessing the appropriate grenade pin, thereby reducing the possibility of being claimed and used against its owner; it has multiple safety interlocks to minimize inadvertent actuation and physical restraints to preclude injury in the event of catastrophic failure; it has an adjustable actuator; it can be easily uploaded to change or blend color combinations at will; and it contains an internal environmentally friendly renewable power source that facilitates its use as mine-like device actuated by any of a variety of mechanical triggering mechanisms.

Although the description above contains many specificities, these should not be construed as limiting the scope of the invention but as merely providing illustrations of some of the presently preferred embodiments of this invention. Various other embodiments and ramifications are possible within it's scope. For example, it may have applications in a variety of civil law enforcement, and even military environments. When uploaded with other than standard paint balls (126), the device has application as a neutralizing agent for chemical spills, or even a fire extinguisher that could be loaded, targeted, deployed, and actuated under extreme conditions. The size of the device may be varied to accommodate a variety of individualized applications, while the capacity of the munition (preferred embodiment was paint ball (126)) may be varied without direct relationship with overall device size. Composition of device can vary in accordance with available materials and economic considerations. A variety of man made and naturally occurring, or combination of the two could be employed during construction. The device could be made completely of nonmetallic materials if nondisclosure by metal detectors was advantageous.

Thus the scope of the invention should be determined by the appended claims and their legal equivalents, rather than by the examples given.
