Connecting device for a breathing apparatus
First Claim
1. Coupling means for coupling breathing gas cylinders to breathing equipment, the coupling means being mountable at an end of the cylinders, and comprising a pair of coupling connectors which, in a first operational position, are in a straight line and connectable to two parallel gas cylinders, and a third coupling connector at an angle to said straight line and connectable to a breathing gas conduit leading to said breathing equipment;
- wherein said pair of coupling connectors are mounted on a tubular main body having a longitudinal passageway which communicates with passageways through each of said coupling connectors;
wherein a longitudinal axis of said tubular main body defines an arcuate angle with said straight line defines by said pair of coupling connectors in said first operational position;
wherein at least one of the connectors of said pair of coupling connectors is pivotable about said tubular main body independently of the other connector of said pair, from said first operational position to a second protected parking position, wherein the coupling means is a T-coupling having two connectors which project out from a tubular main body and connect with a passageway in said body, and wherein at least one of the connectors can be adjusted angularly, wherein the passageway in the tubular main body is connectable with a face mask;
wherein the other of the connectors is fixed and connects with a breathing gas cylinder; and
wherein the pivotable connector is available for connection to a cylinder replenishing conduit, a further breathing gas cylinder or corresponding breathing equipment carried by another person.

Abstract
Means are provided for connecting at least one breathing gas cylinder to a face mask or like device in breathing equipment of the kind used by firemen and divers, for instance. The means includes a three-way coupling (5) in which at least one of the connections is comprised of a hose connector (10) which can be adjusted angularly in relation to the two remaining connections (9, 13). The coupling means can be used for different purposes and is relatively insensitive to external influences.
