ABSTRACT:

BACKGROUND OF THE INVENTION
The present invention relates to a non-lethal projectile system and, more particularly to non-lethal projectiles that deliver an inhibiting and/or marking substance to a target, especially a living target. Even more particularly, the present invention relates to non-lethal projectile systems including a capsule, most preferably a generally spherical capsule, containing an inhibiting and/or marking substance, and tactical methods for using the non-lethal projectile systems in combination with a launch device in order to most effectively inhibit, impair, or disable the living target in a less-than-lethal way. The projectile systems of the present invention, upon impact with the living target, provide optimized dispersal of the inhibiting and/or marking substance on and about the target, and in particular, provide an improved mechanism for delivering the inhibiting substance to the target's face, without requiring that the projectile impact the target's face. Further, the projectile system is designed such that deployment facilitates its effectiveness by creating sufficient force, upon impact with the target, to cause the target to move his, her or its face into the dispersing substance, while at the same time experiencing impairment, or temporary disability as a result of the impact. Specifically, the non-lethal projectiles are able to be launched with sufficient non-lethal force to immediately slow and/or stop a moving target, before the inhibiting substance carried thereby affects the target. Additionally, the projectile systems of the present invention are easier and cheaper to manufacture than heretofore known projectiles, are effective at safer, stand-off distances as well as at close range distances, are easily integrated into normal officer training programs, and can be used with conventional, as well as custom, launchers.
Steadily rising crime rates have led to an increased need for technologically enhanced crime devices. There is particularly a need for non-lethal devices that are capable of at least temporarily incapacitating, slowing or inhibiting a suspected criminal and/or marking such individuals for later identification. As populations increase, the risk that a criminal will be surrounded by or in close proximity to innocent persons when officers are trying to subdue him/her also increases. Whereas non-permanently injuring an innocent bystander, while subduing a suspected criminal, is acceptable, killing the bystander is not. Thus, there is great need for non-lethal (or less-than-lethal), highly effective weapons that may be used by officers and others to slow, stop and/or mark criminals. Presently available, non-lethal devices include, for example, stun guns, mace, tear gas, pepper spray devices and similar devices that impair the vision, breathing or other physical or mental capabilities of the target.
One attempt to provide a non-lethal device for delivering an inhibiting substance is shown in U.S. Pat. No. 3,921,614, issued to Fogelgren for a COMPRESSED GAS OPERATED GUN HAVING VARIABLE UPPER AND LOWER PRESSURE LIMITS OF OPERATION, which patent is incorporated herein by reference in its entirety. Fogelgren describes a gas-operated gun and associated projectiles. In one illustrated embodiment, a projectile consists of a projectile casing that houses a structure in which a firing pin is situated so as to detonate a primary charge upon impact of the projectile with a target. Deterioration of the primary charge causes the expulsion of a load carried in a load chamber. The load chamber may contain various types of load, such as tear gas, dye, flash-powder or wadding.
Another embodiment illustrated in the Fogelgren patent consists of a projectile casing that encloses a body member, which, together with a frontal member, defines a load chamber. The body member and the frontal member are attached so as to be readily separable in flight to enable the load to escape from the load chamber and to proceed to the desired target. In this embodiment, the load is buckshot or plastic pellets.
A further embodiment of the projectile shown by Fogelgren stores a portion of a compressed gas, utilized to expel the projectile, to be used to expel a load upon striking a target. Upon firing, an outer body member separates from an inner body member thereby exposing and releasing a holding pin, which holding pin prevents premature release of the projectile's load. Apertures, from which the load is expelled upon impact, are sealed with wax to prevent expulsion of the load before the projectile impacts the target. The portion of the compressed gas used to expel the load is stored in a rear chamber of the projectile during flight, while the load is stored in a forward chamber. When the projectile strikes the target, the compressed gas is released, forcing the load through the apertures and out of the projectile.
An additional embodiment of the projectile shown by Fogelgren consists of outer members that form a container into which is fitted a breakable glass vile. Rearward of the breakable vile, padding is provided to prevent breakage of the vile upon firing of the projectile. Forward of the vile is a firing pin assembly against which the breakable vile impacts, as it shifts forward within the members forming the container, upon impact. As with the above embodiment, a holding pin, which normally prevents the breakable vial from shifting forward in the container, is expelled as an outer body member separates from an inner body member. This allows the breakable vial to shift forward upon impact, shattering the breakable glass vial against the firing pin. The breakable vile contains a load to be delivered to the target, which is delivered through apertures near the front of the projectile upon the shattering of the breakable glass vial. The vile may be charged with a compressed gas so as to provide a, charged load.
Disadvantageously, the projectiles described by Fogelgren, particularly those projectiles described that would be suitable for delivering loads such as tear gas or dye, are complicated and expensive to manufacture. The embodiment employing pressurized gas to both expel the projectile and to expel the load upon impact with the target requires a great amount of pressurized gas, that is, a sufficient quantity to both fire the projectile and to provide the portion of pressurized gas necessary to ensure expulsion of the load. In addition, such embodiment requires complicated and tedious methods to manufacture components such as a microminiature ball valve (through which the portion of the pressurized gas enters the rear chamber upon firing), wax sealer within each of the plurality of apertures and a holding pin that must fall away from the projectile in flight.
The embodiment employing the breakable glass vial is also complicated to manufacture, because it also employs a holding pin that must fall away during the flight of the projectile and employs numerous structures that must be precisely fitted together to allow them to separate during firing and in flight. This embodiment also must be carefully handled so that the breakable glass vial does not shatter while being handled by the user. This can be particularly problematic, for example, when the Fogelgren device is being used by a police officer in pursuit of a fleeing criminal (or when used by a police officer threatened by a suspected criminal). Thus, significant room for improvement still exists in the development of non-lethal projectiles.
Another approach to providing non-lethal projectiles for delivering an inhibiting substance to a living target is suggested in U.S. Pat. No. 5,254,379, issued to Kotsiopoulos, et al., for a PAINT BALL, which patent is hereby incorporated herein by reference in its entirety. The Kotsiopoulos, et al., device is directed primarily to a paint ball projectile for delivering a load (or blob) of paint to a target, and for expelling the blob of paint onto the target upon impact. The paint ball shown by Kotsiopoulos, et al. consists of a shell that fractures in a
