Problems solved by technology

[0005] Unfortunately, however, such manually operable connectors are prone to undesired loosening due to shock, abrasion, vibration, etc., experienced during use in hazardous and / or hazardous environments
Leakage can occur when the connector comes loose from the compressed air tank, reducing the available supply of breathable air

Embodiment Construction

[0016] see figure 1 A self-contained breathing apparatus (SCBA) 10 constructed in accordance with the principles of the present invention is shown including a compressed air tank 12 , ie, an oxygen tank, and a docking assembly 14 including a connector 21 . In one form, the SCBA unit or docking assembly 14 may be based on or include a modification of the Rapid Insertion Connector (RIC) or Universal Air Connector (UAC) component of the Strobe-S4 SCBA, available from Wisconsin Bought from Pleasant Prairie Interspiro, Inc. The compressed air tank 12 includes a head 13 and a connecting member or nozzle 16 . The nozzle 16 includes a plurality of threads 18 provided on its outer surface and a fitting hole 20 provided inside it. Connector 21 is adapted to threadably engage nozzle 16 such that bore 20 accommodates a corresponding fitting tip 44 supported by connector 21 (eg, Figure 4 shown) and sealingly engages it. Connector tip 44 is disposed in communication with the SCBA's flu...

Abstract

A docking assembly for a self-contained breathing apparatus comprises a seat, a coupler, a pawl, and a spring. The self-contained breathing apparatus generally includes a compressed air tank having a head and a nozzle, the compressed air tank being adapted to deliver breathable air to a user. The seat of the docking assembly is adapted to releasably retain the head of the compressed air tank. Thecoupler comprises a plurality of circumferentially spaced teeth and a handle and is adapted for threaded engagement with the nozzle of the compressed air tank. The pawl is mounted to the seat for pivotal displacement and adapted to engage at least one of the plurality of teeth on the threaded coupler to lock the threaded coupler onto the nozzle. The spring biases the arm into the locked position.

Description

[0001] Cross References to Related Applications [0002] This application is based upon and claims the benefit of priority from US Provisional Patent Application No. 60 / 757,160, filed January 5, 2006, the entire contents of which are hereby incorporated by reference. technical field [0003] The present invention relates generally to self-contained breathing apparatus and, in particular, to locking mechanisms for use on docking assemblies associated with self-contained breathing apparatus. Background technique [0004] High pressure breathing apparatus, commonly referred to as self-contained breathing apparatus (SCBA), require a stored supply of breathable air, ie a tank of compressed air, and a delivery system to deliver the breathable air to the user. A common SCBA delivery system generally includes a regulator, one or more catheters, and a mask. Also, threaded connectors are commonly used to fluidly connect the compressed air tank with the delivery system. One known thr...
