Abstract

A driving disc for a floor treating machine comprises a disc element 1 for supporting a cleaning pad, a coupling element 2 for coupling the disc to a drive member of the floor treating machine, and a hollow, flexible tube 3 connected to both elements 1, 2. The tube may be made of rubber and may be inflated via valve 4. It may be connected to elements 1, 2 by an adhesive. The tube is found to reduce vibrations at relatively high rotary speeds. <IMAGE>

Description

DRIVING DISK The present invention relates to a driving disk for floor treating machines, more in particular for singledisk floor treating machines.
Various types of floor treating machines are known in the art. They are generally provided with an electric motor driving one or more rotary brushes or disk devices for scrubbing or polishing floors.
The larger types of floor treating machines are usually supported on wheels which may be electrically driven and are used for treating large floor areas such as in hotels, office buildings and the like. They are primarily used to clean the floor area.
The smaller types comprise a single rotary disk and are hand held by means of a handle. These machines are mainly used to provide floor-care and to that end the rotary disk is equipped with a replaceable polishing or cleaning pad.
In the known floor treating machines, the driving disk may be attached to the machine in a number of ways. For instance, in single-disk floor treating machines the driving disk may comprise the actual disk device, coupling means for attaching the assembly to the floor treating machine and an interface made of foam rubber connecting the disk device to the coupling means. This foam rubber interface reduces the vibrations which may occur in operation, and which may be quite severe for single-disk machines at operating at rotary speeds of 200 rpm and above. However, the use of foam rubber has a number of draw backs. Its application in hospitals is sometimes prohibited on hygiene grounds, its mechanical strength leaves to be desired and it cannot be efficiently adhered to the synthetic materials used for the disk device.Finally, a floor treating machine employing a foam rubber containing driving disk may only be used under dry circumstances because foam rubber tends to absorb water.
It is the purpose of the present invention to provide an improved driving disk for a floor treating machine, which driving disk does not have the above-mentioned or other disadvantages.
Accordingly, the present invention provides a floor treating driving disk comprising a disk device for supporting a pad and coupling means for attaching the assembly to the rotary axis of a floor treating machine, characterized in that the coupling means are connected to the disk device by means of a hollow element made of a flexible material.
It is preferred that the hollow element is concentric with the disk device. More preferably, the hollow element has a tubular shape, or, even more preferred, a toroidal shape. It proved to be particularly advantageous if there is provided a valve by which the hollow element can be pressurised According to another aspect of the present invention, there is further provided floor treating machine, preferably a single-disk floor treating machine, which comprises the driving disk according to the invention.
The driving disk of the present invention comprises in the first place the actual disk, a round flat element having a diameter of approximately 14-20 inches, which may be manufactured from metal or a synthetic material.
Its purpose is to form a pick up and support for the polishing or cleaning pad which is brought into contact with the floor surface under operating conditions. The pad may be attached to the disk by means of known techniques, such as adhesive stripes.
For operation, the disk is connected to the rotary axis of a floor treating machine via a coupling means. This is preferably also disk-shaped and provides a reliable coupling mechanism to the rotary axis. It is advantageous to use a quick-release coupling system.
According to the invention, the coupling means and the disk device are connected to one another by means of a hollow element which is made of a flexible material, such as rubber or another - preferably synthetic material. The element constitutes a flexible interface which effectively reduces the vibrations occurring at higher rotary speeds, e.g. of approximately 200 rpm and above.
The hollow element should be concentric with the disk device in order to avoid vibrations imparting the ease of handling of the floor treating machine.
The hollow element has preferably the shape of a tube. A plurality of symmetrically arranged tubular elements may be used, but a single closed tube in the form of a torus is preferred. If the thickness of the material used is sufficiently large, a self supporting structure may be formed. However, it was found to be particularly useful to use a pressurised toroidal element having somewhat thinner walls which would otherwise collapse under the weight of the floor treating machine. The element may be pressurised with a suitable gas, preferably air, via a conventional valve. A properly dimensioned commercially available rubber inner tube, for example a 16 x 1.75 x 2 inch tube, was found to function very satisfactory. Suitable operating pressures are approximately 1.5 bar, depending on the weight of the floor treating machine.
The flexible, hollow element can be connected to the disk device in a number of ways. The preferred method proved to be to use a suitable, commercially available adhesive.
The man skilled in the art will have no difficulty to dimension the hollow flexible connective element of the driving disk in accordance with the particular requirements of the floor treating machine with which the assembly is to be used.
It will be understood that the driving disks according to the invention can also be used on floor treating machines operating at lower speeds. In all cases they provide the advantages of a reliable construction and hygienic safety. The latter point may be an important consideration when they are to be used in hospitals and the like.
The invention will now be further illustrated by means of the following Figure, in which a preferred embodiment of the driving disk according to the invention is shown.
The Figure is a schematic perspective view of a driving disk according to the invention, wherein a section has been cut away to provide a better view.
In the Figure there is depicted a driving disk comprising a disk device 1 and a coupling means 2 including a quick release pick up coupling for connecting the assembly to a floor treating machine.
The disk device 1 and the coupling means 2 are connected to one another by means of a toroidal rubber tube 3 which is equipped with a valve 4. The tube 3 is attached to the disk device and the coupling means by means of adhesive. Before operation, the tube is pressurised with air to about 1.5 bar.
