Abstract

Abstract A composite foot is described for supporting and moving pneumatically a machine. The foot comprises a nozzle (12) for ejecting pressurized air, fixed to the machine base (10) to which a substantially disc-shaped element (30) is associated, being connected to the nozzle (12) in a substantially swingable manner, between said disc-shaped element (30) and the machine base (10) there being provided air sealing means (38) in order that air is ejected by said nozzle (12) only toward the plane on which the machine is placed, thus generating in practice a pressurized air cushion which keeps the machine itself upraised with respect to the plane, thus allowing a quick and precise shifting thereof.

Claims Analysis

Total Claims: 9
Claim 1
Independent Claim 117 words
A composite foot for supporting a machine, characterized by comprising a compressed air ejecting nozzle (12) fixed to the machine base (10) and connected to a suitable compressed air feeding source, to a portion of ejecting nozzle (12) projecting at the outside of base (10) there being applied in a swingable way a substantially disc-shaped body (30) for application to the support plane of the machine, between said disc-shaped body (30) and the machine base (10) there being provided resilient means (38) for allowing said swinging movements of disc-shaped body (30) and forming at the same time a sealing means for the compressed air, whereby the latter is exclusively directed toward the support plane of the machine.
Claim 2
Dependent Claim 46 words
A composite foot according to claim 1, characterized by the fact that the ejecting nozzle (12) comprises a threaded tail member (14) to be screwed in the machine base (10) and, within the latter, in a fitting (16) connected to a compressed air feed pipe (18).
Claim 3
Dependent Claim 82 words
A composite foot according to claim 2, characterized by the fact that the tail member (14) extend itself in a substantially cylindrical body (20), one face of which is in engagement with the outer surface of machine base (10), said body (20) having at the inside thereof a cavity (22) that receives compressed air from a longitudinal conduit (20) formed within the threaded tail (14), said cavity (22) being adapted to provide an expansion chamber of the compressed air from conduit (26).
Claim 4
Dependent Claim 28 words
A composite foot according to claim 3, characterized by the fact that the lower end of said substantially cylindrical body (20) shows a ring-shaped outer radial flange (28).
Claim 5
Dependent Claim 67 words
A composite foot according to claims 1 and 4, characterized by the fact that the disc-shaped body (30) is formed at one of its faces with a substantially cylindrical seat (32), the diameter and height of which are of slightly greater size than those of the outer radial flange (28) of cylindrical body (20), which consequently remains in any case at the inside of the seat (32).
Claim 6
Dependent Claim 45 words
A composite foot according to claim 5, characterized by the fact that the disc-shaped body (30) has on its other face a substantially cylindrical cavity (36) in which is partially housed a substantially ring-shaped body (38) of elastic material such as rubber or the like.
Claim 7
Dependent Claim 34 words
A composite foot according to claim 6 characterized by the fact that the outer diameter of the ring-shaped member (38) is slightly smaller than the diameter of cavity (36) of the disc-shaped body (30).
Claim 8
Dependent Claim 36 words
A composite foot according to claims 6 and 7 characterized by the fact that in any operating condition the ring-shaped member (38) is always in contact with both the base (10) and the disc-shaped body (30).
Claim 9
Dependent Claim 45 words
A composite foot according to claim 6, characterized by the fact that the disc-shaped body (30) has a recess (34) in which the cylindrical body (20) is inserted, the diameter of said recess (34) being slightly greater than the outer diameter of cylindrical body (20).
