Barrier piercing firehouse nozzle assemblies

A barrier piercing firehose nozzle assembly, comprising:

• a nozzle inlet housing having a first inlet housing end, a second inlet housing end and an inlet housing interior extending from the first inlet housing end to the second inlet housing end;
• a hose coupling at the first inlet housing end of the nozzle inlet housing, the hose coupling configured to facilitate coupling of the nozzle inlet housing to a fire hose;
• a spray nozzle disposed in fluid communication with the inlet housing interior at the second inlet housing end of the nozzle inlet housing;
• an applicator connecting portion disposed in fluid communication with the inlet housing interior at the second inlet housing end of the nozzle inlet housing and in adjacent and parallel relationship to the spray nozzle;
• an applicator coupling carried by the applicator connecting portion;
• a barrier-piercing applicator disposed in fluid communication with the applicator connecting portion, the barrier-piercing applicator selectively telescopically deployable between a retracted position and an extended position and including:
• an applicator base housing disposed in fluid communication with the inlet housing interior, the applicator base housing having a housing coupling coupled to the applicator coupling of the applicator connecting portion;
• at least one intermediate applicator segment disposed in fluid communication with and telescopically-extendable from the applicator base housing;
• a terminal applicator segment disposed in fluid communication with and telescopically-extendable from the at least one intermediate applicator segment, the terminal applicator segment having a tapered discharge end;
• at least one discharge opening in the terminal applicator segment;
• a plurality of segment locking mechanisms on the barrier-piercing applicator and configured to releasably secure the barrier-piercing applicator in the extended position, each of the plurality of segment locking mechanisms comprising:
• a male lock ring carried by a first corresponding one of the applicator base housing, the at least one intermediate applicator segment and the terminal applicator segment, the male lock ring having:
• a lock ring body;
• a ring gap interrupting the lock ring body;
• and
• at least one lock tab extending from the lock ring body;
• and
• a female lock ring carried by a second corresponding interfacing one of the applicator base housing, the at least one intermediate applicator segment and the terminal applicator segment, the female lock ring having:
• a female lock ring body with a female lock ring opening;
• an interior ring surface facing the female lock ring opening;
• and
• at least one lock tab seat in the interior ring surface, the at least one lock tab seat configured to accommodate the at least one lock tab of the male lock ring in the extended position of the barrier-piercing applicator and configured to release the at least one lock tab of the male lock ring responsive to selective rotation of the second corresponding interfacing one of the applicator base housing, the at least one intermediate applicator segment and the terminal applicator segment with respect to the first corresponding one of the applicator base housing, the at least one intermediate applicator segment and the terminal applicator segment;
• and
• a selector valve in the inlet housing interior, the selector valve selectively deployable in a first valve position wherein the selector valve establishes fluid communication between the hose coupling and the spray nozzle and a second valve position wherein the selector valve establishes fluid communication between the hose coupling and the barrier-piercing applicator.
