Abstract

A projectile deployment system includes an entangling projectile that includes a pair of pellets and a tether connecting the pellets. A projectile casing includes a pair of sockets, each socket sized to carry one of the pair of pellets, each of the sockets including a longitudinal axis, the pair of sockets being positioned relative to one another such that the longitudinal sockets diverge horizontally away from one another while at least a portion of one of the sockets is arranged vertically higher than another of the sockets. A selectively activatable pressure source is capable of expelling the entangling projectile from the projectile casing toward a subject. A launcher carries an activator operable to activate the pressure source to expel the entangling projectile from the projectile casing toward the subject.

Claims (29)

1. A projectile deployment system, comprising:

an entangling projectile, including a pair of pellets and a tether connecting the pellets;

a projectile casing, including:

a pair of sockets, each socket sized to carry one of the pair of pellets, each of the sockets including a longitudinal axis, the pair of sockets being positioned relative to one another such that the longitudinal sockets diverge horizontally away from one another while at least a portion of one of the sockets is arranged vertically higher than another of the sockets;

a selectively activatable pressure source, the pressure source being capable of expelling the entangling projectile from the projectile casing toward a subject; and

a launcher, carrying an activator operable to activate the pressure source to expel the entangling projectile from the projectile casing toward the subject.

2. The system of claim 1 , wherein the entangling projectile is removably installed within the projectile casing.

3. The system of claim 2 , wherein the entangling projectile is completely removed from the projectile casing after being expelled from the projectile casing.

4. The system of claim 3 , further comprising one or more engagement hooks coupled to at least one of the pair of pellets, the engagement hooks being operable to engage clothing worn by a subject of the deployment system to aid in retaining the entangling projectile about the subject.

5. The system of claim 4 , wherein the one or more engagement hooks are mounted to at least one of the pair of pellets.

6. The system of claim 5 , wherein the one or more engagement hooks are fixed relative to the at least one of the pair of pellets.

7. The system of claim 1 , wherein the projectile casing is removably coupled to the launcher.

8. The system of claim 1 , wherein the sockets are vertically offset relative to one another and extend in planes parallel to one another.

9. A projectile deployment system, comprising:

an entangling projectile, including a pair of pellets and a tether connecting the pellets;

a projectile casing, including:

a pair of sockets, each socket sized to carry one of the pair of pellets, each of the sockets including a longitudinal axis, the pair of sockets being positioned relative to one another such that the longitudinal sockets diverge horizontally away from one another while at least a portion of one of the sockets is arranged vertically higher than another of the sockets;

a selectively activatable pressure source, the pressure source being capable of expelling the entangling projectile from the projectile casing toward a subject;

a launcher, carrying an activator operable to activate the pressure source to expel the entangling projectile from the projectile casing toward the subject; and

one or more engagement hooks mounted to at least one of the pair of pellets, the engagement hooks being operable to engage clothing worn by a subject of the deployment system to aid in retaining the entangling projectile about the subject.

10. The system of claim 9 , wherein the one or more engagement hooks are fixed relative to the at least one of the pair of pellets.

11. The system of claim 9 , wherein the entangling projectile is removably installed within the projectile casing.

12. The system of claim 11 , wherein the entangling projectile is completely removed from the projectile casing after being expelled from the projectile casing.

13. The system of claim 9 , wherein the projectile casing is removably coupled to the launcher.

14. The system of claim 9 , wherein the sockets are vertically offset relative to one another and extend in planes parallel to one another.

15. The system of claim 9 , wherein the pressure source is carried by the casing and the activator is carried by the launcher.

16. The system of claim 15 , wherein the pressure source comprises a cartridge blank.

17. The system of claim 9 , wherein the pellets overlap one another when installed within the sockets.

18. The system of claim 9 , wherein the sockets are oriented at an angle of between about 25 degrees and about 45 degrees relative to one another.
