Power arm fire hose attachment
View Patent ↗A power arm is designed similar to a rifle stock that can be applied to a fire hose coupling via, for example, a quick detach rail system. The power arm can provide a firefighter with additional control of a fire hose which can be extremely helpful in a hostile environment. The power arm allows a firefighter to use their body as a whole to provide a maximum advantage for controlling a fire hose that is streaming water.
1. A support device for a nozzle comprising:
A nozzle device
A fire hose
And a power arm stock attachment
The nozzle device, fire hose and power arm stock attachment forming an assembly
The nozzle device comprising
A pistol grip
A lever
Said lever actuating a valve
A nozzle inlet, defining a rear of the nozzle device
A nozzle outlet, defining a front of the nozzle device
And a cylindrical coupling matingly received on an external surface of the nozzle outlet
Wherein the nozzle inlet and cylindrical coupling are arranged concentrically about a central lateral axis of the nozzle device, said central axis extending from the nozzle inlet to the nozzle outlet, perpendicularly to the lever
The cylindrical coupling comprising
An internal surface that matingly receives the fire hose, while the cylindrical coupling is coupled to the external surface of the nozzle inlet
And an external surface that includes a dovetail shaped nozzle bracket projecting therefrom
Said nozzle bracket extending from the rear to front of the cylindrical coupling
Wherein the cylindrical coupling receives the power arm stock attachment on the nozzle bracket
The power arm stock attachment comprising
a rifle stock support formed integrally with a rail bracket
The rail bracket comprising a socket shaped to complimentarily mate with the nozzle bracket by a dovetail connection
Such that the power arm stock attachment is mounted to the nozzle bracket by sliding the power arm stock attachment along the external surface of the rail bracket in a direction from the rear of the nozzle device toward the front of the nozzle device
Wherein
In use, water flows through the fire hose into the nozzle device, through the valve and is expelled laterally from the nozzle outlet
Such that a water force is created by the water opposite the direction of water expulsion
Said water force driving the power arm stock attachment to a torso of a user and the power arm stock attachment is frictionally retained on the nozzle bracket.
