Abstract

A line launcher includes a launcher body extending along a longitudinal axis between a rear end and a front end. The line launcher further includes a handle, a trigger, and a removable battery. The line launcher further includes a compressed gas charge assembly. The line launcher further includes an elongated barrel coupled to the body at the front end. The line launcher further includes a throwline assembly, the throwline assembly including a projectile and a throwline, the projectile insertable into and ejectable from the elongated barrel.

First claim

What is claimed is:

1. A line launcher, the line launcher comprising:
a launcher body extending along a longitudinal axis between a rear end and a front end;
a handle;
a trigger;
a removable battery;
a compressed gas charge assembly, wherein the compressed gas charge assembly comprises a motor, a compressor, and a pressure adjustor, wherein the motor is powered by the battery;
an elongated barrel coupled to the body at the front end; and
a throwline assembly, the throwline assembly comprising a projectile and a throwline, the projectile insertable into and ejectable from the elongated barrel.

2. The line launcher of claim 1 , wherein the elongated barrel is removably coupled to the body at the front end.

3. The line launcher of claim 1 , wherein the removable battery is removably coupled to the handle.

4. The line launcher of claim 1 , wherein the compressed gas charge assembly comprises a motor, a compressed gas tank, a valve, a pressure level activator and a pressure adjustor.

5. The line launcher of claim 1 , wherein the throwline assembly further comprises a reel and a throwline container.

6. The line launcher of claim 5 , wherein the reel is mounted to the body proximate the front end.

7. The line launcher of claim 1 , wherein the throwline assembly further comprises a brake.

8. The line launcher of claim 1 , wherein the handle is a first handle and further comprising a second handle.

9. The line launcher of claim 8 , wherein the first handle is disposed proximate the rear end and the second handle is disposed between the first handle and the front end along the longitudinal axis.

10. The line launcher of claim 1 , further comprising a laser sight mounted to the body.

11. The line launcher of claim 1 , further comprising a ram rod removably coupled to the elongated barrel.

12. A line launcher, the line launcher comprising:
a launcher body extending along a longitudinal axis between a rear end and a front end;
a handle;
a trigger;
a removable battery;
a compressed gas charge assembly;
an elongated barrel coupled to the body at the front end; and
a throwline assembly, the throwline assembly comprising a projectile, a throwline, a reel, a throwline container, and a brake, the projectile insertable into and ejectable from the elongated barrel, the reel mounted to the body proximate the front end.

13. The line launcher of claim 12 , wherein the elongated barrel is removably coupled to the body at the front end.

14. The line launcher of claim 12 , wherein the removable battery is removably coupled to the handle.

15. The line launcher of claim 12 , wherein the compressed gas charge assembly comprises a motor, a compressor, and a pressure adjustor.

16. The line launcher of claim 12 , wherein the compressed gas charge assembly comprises a motor, a compressed gas tank, a valve, a pressure level activator and a pressure adjustor.

17. The line launcher of claim 12 , wherein the handle is a first handle and further comprising a second handle.

18. The line launcher of claim 12 , further comprising a ram rod removably coupled to the elongated barrel.
