Abstract

The device is based on an air cushion formed using a curved piece of tubing with a manually or mechanically operated first air valve for supplying air, either from a compressed air tank or by generating a vacuum inside the pipe so that air is sucked in. A manually or mechanically operated second air valve is used to remove the air in order to eliminate the air cushion.
