Abstract: A buoyancy compensator adjustment for a diver's buoyancy compensator having a backpack and a back portion terminating in side and shoulder portions. The shoulder portions and side portions are each secured by straps overlying the chest extending from the side portions to the shoulder portions. The straps are looped through belt loops to provide a bight under tension which is loosened upon lifting or disengaging one of the belt loops.

Abstract: 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.

Abstract: 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.

Abstract: A strap and retainer for a diver's mask, or other mask to be held on a user's face. The retainer is comprised in part of a molded portion of the frame of the mask with a movable clip portion therein which is pivotally mounted into a molded pocket in the frame of the mask that receives the clip. The clip comprises a main lever portion that is pivotally mounted in the pocket with an angular spring arm portion that rides within the base of the pocket. At the other end of the pivotal lever portion from the spring portion is an angular barb or tooth having a substantially upright angular face portion and a sloping angular face portion.

Abstract: The following specification discloses a buoyancy compensator bladder and method of manufacture therefor. The bladder has a plurality of gussets implaced therein in order to rigidify and maintain a pre-established general configuration to the bladder. A plurality of insets or pleats are implaced around the shoulder area to provide for a generally arcuate curvilinear conformation therearound. A nylon plastic coated material is used for the gussets having one side that can be bonded to the inner side of the bladder, while the other side is formed from a nylon having a higher melting temperature. The gussets that are made from the nylon coated material are folded and implaced within the bladder or cavity formed from a plurality of sheets, the combination of which is brought together and heatset by means of an RF heater, or other suitable heater.

Abstract: The following specification sets forth a conformable buoyancy compensator that conforms to a user's body in a uniform manner during use. The buoyancy compensator incorporates an interior bladder having a plurality of heat sealed pleats or insets around the shoulder area in order to provide conformity of the buoyancy compensator to a user's body. The bladder further comprises interior reinforced gussets that retain the conformation of the bladder in a plurality of air channels or pockets that conform to the frontal areas of a user's body. The arm openings are free and open for a user to extend one's arms. Between the front and back portions of the air channels are a plurality of side panels that can be made of spandex, elastic, or can be configured of suitable strapping. The buoyancy compensator has vents. Vented pockets are provided for the receipt of a second stage regulator therein, as well as providing for other specific storage of items used by a diver.
