Abstract
An integral floatation or buoyancy compensating device and weight assemblies for divers. The buoyancy compensating device provides an integral back pack which is used to support the air tank of a conventional scuba diving type. At least one and preferably two quick release weights are mechanically attached to the buoyancy compensating device usually at an integral waistband and worn around the waist similar to conventional hip style weights, but are individually releasable by a quick release mechanism from the waistband rather than normally jettisoning an entire band. The band to which the weights are attached are an integral lower extension of the buoyancy compensator or buoyancy compensating device. Weight release is simple and one handed with no band to entangle or become entrapped beneath the tank or other piece of equipment normally worn by the diver. Weight location is set about the waist near the hands when in a relaxed position. Weight release is effected by a simple grasping and squeezing action. Thus, there is no dependency on a secondary device or reaction to a remote release to release the weights. The weights are actually in-hand during the release process and free from entanglement with other gear. The weight assembly portion of the invention may also be used with a separate weight belt such as when the buoyancy compensating device is not used.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
