Abstract

The invention relates to a bearing provided with a carrier surface along which a platform (6) with people or other loads can move on an air cushion, preferably without a motor, wherein the air cushion can be maintained without too great an effort. According to the invention, the form thereof is that of a box (1) with a perforated surface for the discharge of air. The openings in the surface are provided with automatic valves (5) which are connected to the inner area of the box (1). The cavity on one side of the moveable element of the valve (5) is connected to the opening on the upper side of the box (1). The cavity on the other side of the moveable element of the valve (5) is connected to the outer air. The openings on the side of the valve housing are connected to the inner area of the box (1).

Dependent claims

A bearing provided with a carrier surface (1) for moving a platform (6) on an air cushion, whereby the bearing has the form of a box with a perforated surface and the perforated surface has openings in the carrier surface (1) of the box for the discharge of air, which is pressed into the inner area of the box,

whereby the openings in the carrier surface (1) of the box are connected to the inner area of the box via automatic valves, and
whereby each of the automatic valves comprises a movable element, which is pressed against the openings in the carrier surface (1) of the box by a spring (9, 15), characterized in that
the movable element is a piston (8, 12) which moves in a valve housing (5), and
in that valve openings (7) are arranged near the openings in the carrier surface (1) in a side wall of the valve housing (5), such that the piston (8, 12) releases the valve openings (7) when the automatic valve is open, so that air can escape from the inner area of the box through the valve openings (7) and the openings in the carrier surface (1) of the box.
