The specification discloses a diver's snorkel having an elongated tube with a fitting at the end incorporating a mouthpiece. Distal from the mouthpiece is a water drainage purge chamber extending away from the mouthpiece. The entrance conduit interconnecting the elongated tube to the mouthpiece and the purge chamber is at an angle sloping downwardly from the mouthpiece during use. The purge chamber is angled inwardly toward a diver's chin when in use so that the axis thereof is at an angle to the axis of the mouthpiece. The purge chamber has a purge valve distal from the mouthpiece and incorporates a chamber of significant volume for drainage from the mouthpiece and the elongated tube in an unobstructed manner.

The specification herein sets forth a combination buoyancy compensator, backpack and suspension system for divers. The suspension system incorporates a spider which is made of elastomeric foam and a knitted material that conforms closely to a user's body. The backpack is formed from an inverted T, the lateral portions of which surround a user's waist and the upright portion is adapted for receipt of a cylinder of breathing gas. The buoyancy compensator is attached to the spider at the shoulder portions and the waistband portions. The attachment is by means of adjustable loops which allow for independent suspension of the buoyancy compensator so that when it is filled it does not bind a diver. The straps interconnecting the spider, shoulder portions and the waistband portion are in a crisscross configuration to allow for freedom of movement of a diver's arms.

Diver's buoyancy compensator and backpack with independent suspension

The invention described herein is a buoyancy compensator for a diver having a single thickness wall formed of substantially non-stretchable material that has been coated with a meltable plastic. The buoyancy compensator walls on the interior portion with the meltable plastic are adhered to each other in rounded areas or ribs having rounded ends to avoid stress when the buoyancy compensator is under pressure and provide a conformation to the buoyance compensator with a limitation of expansion in different areas of the walls of enhancement of the overall configuration and improved buoyancy relationship of a diver at a particular portion of the buoyancy compensator. The entire buoyancy compensator is served by inflation means and overexpansion gas valving means. The buoyancy compensator is fitted and secured by means of belts and shoulder straps for respective waist adjustment and shoulder and side portion adjustment.

Adjustable diver's belt

A diver's buoyancy compensator belt to be used with a diver's buoyancy compensator of the type that allows for increases and decreases of air to be provided thereto, depending upon the amount of buoyancy that is required. The buoyancy compensator belt has a first belt made of webbing for attachment to a buoyancy compensator and a backpack that in turn receives a tank connected thereto. The buoyancy compensator belt retains the buoyancy compensator around a diver's waist at distinct locations to allow for movement thereof which allows for the belt to expand and contract, due to the belt being made from an elastomeric material. The elastomeric material allows for a stretching and contraction of the belt, due to various pressure conditions and can be made of elastomeric foam having discrete cells therein. As the belt expands and contracts due to the discrete cells being pressurized at various depths, it compensates for the depth. This provides for overall control of the belt that is accommodated for at various depths so that the belt can expand and contract commensurately with wetsuits underlying the belt that are also made of foamed elastomeric cellular material.

A buoyancy compensator insertable backpack is disclosed herein in the form of a configured insert having an inverted T conformation. The inverted T conformation has an upright portion with ribs thereon which provide rigidity to the upright and includes at least one set of slits therethrough in order to secure a breathing gas tank by a metal band passing therethrough and around the tank. The lower or transverse portion of the inverted T shaped backpack is curved to follow the contour of a person's torso so that support can be provided to the upright portion by having a load distributed across a person's torso in the pelvis, small area of the back, or hip area. The entire insertable backpack is implaced with a buoyancy compensator so as to provide for support of a breathing gas tank on the backpack within the buoyancy compensator, all of which are secured on a user's body for providing buoyancy compensation and attendant support of a breathing gas tank.
