DETAILED DESCRIPTION OF THE INVENTION

Best Mode

[0025] The present invention will now be described more fully hereinafter with reference to the accompanying drawings, wherein like numbers refer to like elements throughout. It is to be understood, however, that the detailed description of the various embodiments and specific examples, while indicating preferred and other embodiments of the present invention, are given by way of illustration and not limitation. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art. Many changes and modifications within the scope of the present invention may be made without departing from the spirit thereof, and the invention includes all such modifications.

[0026] The basic situation for use of the present invention is illustrated in FIG. 1, wherein FIGS. 1A, 1B, and 1C illustrate three steps in the use of the invention. In FIG. 1A a defendant 50 fires projectile 40 from firearm 52 toward the knees and ankles of attacker 51 who is armed with a non-lethal weapon 54. Protective cover 2 separates from the projectile core 40 after the projectile exits the firearm 52. In FIG. 1B the projectile 40 impacts the knees of attacker 51 and hooking assemblies 10 deploy on impact. In FIG. 1C the hooking assemblies 10 have fully deployed and entangled the lower legs of attacker 51, immobilizing the legs and causing attacker 51 to fall.

[0027] Components of the grappling-type hooking assembly 10 are shown in FIG. 2. A plurality of treble hooks 12 are attached at swivel points 14 to a hooking assembly core 11. Retaining line 13 is shown in the stored condition wrapped around the hooking assembly core 11. The leftmost end of restraining line 13 is attached to the hooking assembly core 11 at the longitudinal position of the swivel points 14. The rightmost free loop 15 of retaining line 13 is attached during further construction to the projectile central core as subsequently illustrated in FIG. 4.

[0028] Rear, side and front views of the four major components of the retainer and deployment mechanism assembly 20 are shown in FIG. 3. Retainer plate 24 and impact nose 21 are rigidly fixed to opposite ends of deployment rod 23. Retaining spring 22 ensures proper positioning of retainer plate 24 until impact with a target. Holes 25 are used to constrain deployment of hooking assemblies until impact with a target.

[0029] FIG. 4 is an external view illustrating the construction of projectile central core assembly 30, which assembly consists of a central core support tube 31, a plurality of deployment springs 32, and a plurality of stabilizing fins 33. As shown in FIG. 4, each deployment spring 32 is designed with a long straight section on one end, a central tension coil, and a short straight section on the opposite end. The shorter segment of deployment spring 32 is rigidly attached to the central core support tube 31.

[0030] FIG. 5 presents a section side view illustrating the specific parts of a preferred embodiment of the complete projectile assembly 40, which is comprised of a plurality of hooking assemblies 10, a retainer and deployment mechanism assembly 20, and a projectile central core assembly 30. Individual components of assemblies 10, 20 and 30 are illustrated in the stowed, pre-firing condition. Note that retainer plate 24, which is attached to retainer rod 23, secures deployment spring 32. Retainer plate 24 is held in place by retaining spring 22, which pushes central core 31 and impact nose 21 apart.

[0031] FIG. 6 presents the section side view of projectile assembly 40 illustrating separation of the protective cover 2 immediately after the projectile assembly clears the firearm barrel. Protective cover 2 has begun to aerodynamically separate from the remainder of the projectile assembly 40. Retaining ring 22, pushing central core 31 and impact nose 21 apart, ensures that retainer plate 24 maintains the deployment springs 32 in the storage position, by means of the holes in retainer plate 24, until the projectile assembly impacts a target.

[0032] FIG. 7 presents the section side view of FIG. 2 just microseconds after contact of impact nose 21 with target 14. The contact causes impact nose 21 to compress retaining spring 22 while pushing retainer rod 23 rearward through central core tube 31 just enough to separate retainer plate 24 from deployment springs 32.

[0033] In FIG. 8, deployment springs 32 have uncoiled from their storage positions and the coiled spring energy deploys hooking assemblies 10, comprised of elements 11, 12, and 13, outward. The radial momentum imparted to the hooking assemblies 10 by the deployment springs 32 cause the hooking assembly cores 11 to deploy off of the deployment springs 32 and move perpendicularly away from projectile central core 31. Retaining lines 13 begin to uncoil from their storage positions on the hooking assembly cores 11.

[0034] FIG. 9 illustrates the final step in the process. The combination of forward velocity from projectile launch and radial velocity imparted from deployment springs 32 cause hooking assemblies 10 to whip around and subsequently entangle target 14. Grappling hooks 12 attach to target 14, while retaining lines 13 fully unwind to entangle and restrain target 14. Hooking assembly components remain connected to each other through attachment to the deployment springs 32, which are rigidly connected to the central core of the projectile.

[0035] In view of the foregoing, it is obvious that the present invention provides a truly non-lethal round that can be reliably fired from standard firearms to entangle a targeted person's legs without causing harm. This round has adequate accuracy, range, reliability and immobilization capability to be used interchangeably with conventional ammunition for a variety of weapons in multiple tactical situations. The present invention offers improved accuracy over other existing options due to the fact that it travels as a compact fin-stabilized projectile from firearm barrel to target. The present invention is unique in that the entanglement device deploys upon impact with the target. The present invention has improved functional reliability due to the fact that the retaining lines deploy from the individual dispersion devices, thereby minimizing the possibility of malfunction due to premature line entanglements. The present invention has further improved reliability over other existing devices because the entanglement devices more readily and securely attach to the target after deployment due to the multiple treble hooks attached on swivels to each individual dispersion assembly. The use of this non-lethal round has the additional advantage of minimizing harm to non-targeted bystanders.

[0036] It is to be understood that even though numerous characteristics and advantages of the present invention have been set forth in the foregoing description, together with details of the structure and function of the invention, the disclosure is illustrative only. Changes may be made in detail, especially in matters of shape, size and arrangement of parts within the principles of the invention to the full extent indicated by the broad general meaning of the terms in which the appended claims are expressed. The invention includes all such changes and modifications made within the scope of the present invention without departing from the spirit thereof.
