Abstract
A detachable propulsion unit for a scuba diver's air tank is provided to create a hands-free personal propulsion device. The invention comprises an air tank receiving boot member, a propeller motor, power supply and quick connect straps for attachment to the diver. The unit may be quickly released from the air tank in the event of an emergency. A buoyancy and trim control air bag is also provided to help the diver maintain horizontal trim in the water and to control ballast. If desired, an attachment is provided to allow conversion into a hand held propulsion unit separate from connection with the air tank.
Claims17
A propulsion system attachment for mounting on a scuba air tank, said propulsion attachment comprising:
- an air tank receiving boot member,
- a propeller motor,
- a power supply for said motor,
- a motor power control, and
- a belt support strap, said air tank receiving boot member being adapted to fit onto said air tank, said propeller motor being mounted to said air tank receiving boot member such that a propulsion system is created, said motor power control adapted to regulate said propeller motor to effect propulsive movement underwater, said belt support strap being fastened to said air tank receiving boot member, said belt support strap serving to attach said propulsion system onto a user.
A propulsion system for underwater use, said propulsion system comprising:
- an air tank,
- a propeller motor,
- a motor control, and
- a belt support strap, said propeller motor being mounted to said air tank, said motor control regulating said propeller motor to effect propulsive movement underwater, said belt support strap serving to attach said propulsion system onto a user, said propulsion system further comprising a buoyancy bag member, said bag member being adapted to selectively inflated and deflated by said user, whereby a buoyancy effect can be created to counteract a weight of said propulsion system attachment in the water.
An underwater propulsion system unit, said propulsion system unit comprising:
- a propeller motor,
- a power supply for said motor,
- a motor power control, and
- a cylinder member receiving boot member, said power supply being mounted to said cylinder member receiving boot member, said propeller motor being non-collinearly mounted on an adjacent side of said cylinder receiving boot member, said cylinder member receiving boot member being adapted to engage a cylinder member approximating an interior dimension of said cylinder receiving boot member, said motor power control adapted to regulate said propeller motor, whereby a propulsive movement can be effected on said engaged cylinder member when said unit is underwater.
A propulsion system attachment for mounting on a scuba air tank, said propulsion system attachment comprising:
- an air tank receiving boot member,
- a propeller motor,
- a power supply for said motor,
- a motor power control, and
- a belt support strap, said air tank receiving boot member being adapted to fit onto said air tank, said propeller motor being mounted to said air tank receiving boot member such that a propulsion system is created, said propeller motor being non-collinearly positioned at an adjacent side of said air tank receiving boot member, said motor power control adapted to regulate said propeller motor to effect propulsive movement underwater, said belt support strap serving to attached said propulsion system onto a user.
