Abstract
An electric motorized propulsion system (10) for swimmers and divers (12) includes pair of leg-mounted propulsion units (14), each containing sealed electric motors (12), propellers (22), and housings (21), attach to the user's legs to provide thrust, manoeuvrability, and hands-fee operation. A control box (18) containing a motor variable speed control (54) is mountable at a convenient place on the swimmer's body. A battery unit, either simulating a diver's weight belt (16) or provided as a cylindrical hard pack (60) is carryable on the back of the swimmer. Electrical power and signal cables (30, 46) connect the control box to the battery unit and to the propulsion motor housings.
Claims17
A powered propulsion device for a human user such as a swimmer or diver comprising:
- a propeller and propeller drive electrical motor assembly adapted to be releasably mounted to and carried by a leg of a user between the knee and the ankle with the propeller disposed above the sole of the foot in a standing position of the user and to provide propulsive force to the user in a direction along the leg toward the torso when so mounted and operated,
- an electrical battery unit adapted to be supported by the torso of the user,
- a motor control, and,
- electrical conductors connectible between the motor control, the motor assembly, and the battery unit.
A powered propulsion device for a human user such as a swimmer or a diver comprising:
- a pair of similar propeller and propeller drive electrical motor assemblies each adapted to be releasably mounted to a leg of a user between the knee and the ankle with the propeller disposed above the sole of the foot in a standing position of the user and to provide propulsive force to the user in a direction along the leg toward the torso when so mounted and operated, each assembly including a propeller shield,
- an electrical battery unit releasably supportable by the torso of the user,
- a motor control unit manually operable by a user and including a motor speed control, and
- multi-conductor electrical cables connectible between the motor control unit and each of the motor assemblies and between the motor control unit and the battery unit.
