Definitions

  • This invention relates to buoyancy controlling and compensating devices (BCDs) for divers to control their depth in diving waters and their return to surface, and more particularly, to a BCD that envelopes a diving tank rather than the diver.
  • BCDs buoyancy controlling and compensating devices
  • Known prior diving chutes have had diver-attachment portions that are inflatable with low-pressure air that is valve-released from high-pressure air in a diving tank for providing buoyancy. Some of the diver-attachment portions are included in belt-like and suspender-like structure of the diving chutes . Others include back air cells for receiving the low-pressure air for buoyancy control.
  • Objects of patentable novelty and utility taught by this invention are to provide a diving-tank-pocket buoyancy compensator which: does not obstruct bodily movement; can be streamlined for low water resistance; can be adjusted linearly in relationship to a diving chute on a user's body for neutral buoyancy and attitude balance that allows convenient attitude control with movement of the user's body; can prevent over inflation by use of a novel pressure adjustment valve; can be attached to a selection of styles, sizes and shapes of diving chutes; and can be used for containing desired articles when the inflatable air cells are deflated.
  • This invention accomplishes these and other objectives with a diving-tank- pocket buoyancy compensator having an expandable diving-tank pocket that is articulated for containing a diving tank and at least one inflatable air cell.
  • the buoyancy air cell is in fluid communication with a cell end of a buoyancy compensator (BC) tube which has a tank end in fluid communication with an inside periphery of a diving tank through a regulator tube in fluid communication with a regulator valve on the diving tank.
  • An adjustable pressure valve intermediate the tank end and the cell end of the BC tube is provided to maintain a constant pressure and resulting constant volume of air in the buoyancy air cell for maintaining a desired constant buoyancy continuously following any change in air volume and pressure in the buoyancy air cell resulting from inlet of air through the BC tube and outlet of air through a tube-outlet valve in the BC tube and/or through a cell-relief valve in the air cell.
  • the expandable diving-tank pocket and the diving tank are attachable to a predetermined diving-chute harness with at least one tank strap by positioning a pocket-attachment portion of the diving-tank pocket snugly intermediate a chute- attachment portion of the diving-chute harness and a tank-attachment portion of the diving tank.
  • the tank strap is preferably metallic and has a screw-threaded adjustment buckle.
  • FIG. 12 is a side view of an embodiment of the diving-tank pocket for use as a diving bag and having orthogonal ends.
  • An adjustable pressure valve (8) intermediate the tank end (6) and the cell end (4) of the BC tube (5) is employed for maintaining a constant pressure and resulting constant volume of air in the buoyancy air cell (3) without overfill nor under-fill of the buoyancy air cell (3) and for thereby providing a desired constant buoyancy with volume of air in the buoyancy air cell (3). This is accomplished by adjusting for any change in volume and pressure in the buoyancy air cell (3) that may result from intentional inlet of air through an inflation valve (9) in the BC tube (5) and outlet of air through a cell-outlet valve (10) in the BC tube (5) and outlet of air through a cell- relief valve (11) in the buoyancy air cell (3) selectively.
  • a water seal can be employed for restricting entry of water into the control conveyance (21) and thus into the BC tube (5).
  • the water seal can include a resilient sleeve (39) that is articulated and positioned on the overflow outlet (25) as shown in
  • An on-off switch (26) can be positioned in flow-control communication intermediate the control conveyance (21) and the overflow outlet (25) as shown in FIG. 4.
  • the check valve (22) of the adjustable pressure valve (8) is adjustable for preventing overfill of the buoyancy air cell (3) by adjusting spring pressure of the adjustment spring (23) for allowing escape of air through the overflow outlet (25) from pressure in excess of a maximum selected with the adjustment knob (24).
  • the adjustable pressure valve can include a side-mount valve (38) which has the control conveyance (21) in fluid communication from the BC tube (5) and has a conical valve (28) having a point portion (29) of the conical valve (28) positioned cyclically in contact with a valve seat (30) for valved air flow to the overflow outlet (25) as regulated with pressure of the adjustment spring (23) for allowing opening of the conical valve (28).
  • the side-mount valve (38) includes the control conveyance (21) in fluid communication from the BC tube (5) to the check valve (22) that is adjustably spring- loaded with the adjustment spring (23) having tension adjustment with the screw- threaded adjustment knob (24) for allowing bypass of air selectively to the overflow outlet (25).

Abstract

Le compensateur de flottaison pourvu d'une poche de réservoir de plongée selon l'invention intègre une poche de réservoir de plongée (1) extensible qui enveloppe un réservoir de plongée (2), la poche de réservoir de plongée étant articulée pour contenir en plus au moins une cellule d'air de flottaison gonflée (3). La cellule d'air de flottaison est en communication fluide avec une extrémité de cellule (4) d'un tube (5) de compensateur de flottaison (BC) doté d'une extrémité de réservoir (6) en communication fluide avec une périphérie interne du réservoir de plongée par l'intermédiaire d'un tube de régulation (35) et d'une valve de régulation (7) sur le réservoir de plongée. Une valve de pression réglable (8, 38) intercalée entre le l'extrémité du réservoir et l'extrémité de la cellule du tube BC est prévue pour maintenir une pression pré-déterminée et le volume constant d'air résultant dans la cellule d'air de flottaison pour préserver une flottaison constante souhaitée.
