Coupling apparatus for scuba gear
First Claim
1. Apparatus for coupling a gas supply hose to a gas pressure regulator, said apparatus comprising:
- first and second elbow fittings, each of said first and second elbow fittings having opposed first and second ends;
first and second coupling members located at the respective first and second ends of said first elbow fitting and third and fourth coupling members located at the respective first and second ends of said second elbow fitting, said first coupling member being complementary with said third coupling member for coupling the respective first ends of said first and second elbow fittings along a first axis, said second coupling member being adapted for mating engagement with a complementary fitting of the gas pressure regulator along a second axis perpendicular to said first axis, said fourth coupling member being adapted for mating engagement with a complementary fitting of the gas supply hose along a third axis perpendicular to said first axis; and
securing means for securing said second coupling member to the complementary fitting of the gas pressure regulator, such that said second coupling member is substantially secured against rotation about said second axis with respect to the gas pressure regulator.

Abstract
Apparatus for coupling a compressed gas supply hose to a gas pressure regulator includes first and second elbow fittings, each of which has opposed male and female ends. The male end of the first elbow fitting matingly engages a female fitting on the pressure regulator and the female end thereof is in mating engagement with a complementary male end of the second elbow fitting. The female end of the second elbow fitting is attached to a male fitting on one end of the hose. The male end of the first elbow fitting is constrained against rotation about a lateral axis, along which the male end of the first elbow fitting is connected to the pressure regulator, so that the first elbow fitting is substantially inhibited from rotation with respect to the pressure regulator. The first and second elbow fittings are rotatable with respect to one another about a vertical axis extending between the aforementioned lateral axis and another lateral axis, along which the hose is connected to the second elbow fitting. The coupling apparatus allows the diver to turn his head freely in the direction of the air hose without substantial resistance therefrom because the second elbow fitting and a portion of the hose adjacent thereto can be swivelled with respect to the first elbow fitting and the pressure regulator.
