Abstract

A floor treating machine supported at the floor or surface to be treated by means of a work disk arranged beneath a substantially ring-shaped stop member, the work disk being detachably coupled with a drive motor. There are provided two selectively insertable work disks of different diamter and a ring-shaped stop member is provided for each such work disk.

Claims

1. A floor treating machine capable of being supported at the floor to be treated by means of a work disk, said work disk being arranged adjacent a substantially ring-shaped stop, the improvement comprising:

said machine possessing a machine housing, said machine being provided with two work disks of different diameter which are selectively insertable at least partially into the machine housing, one of said work disks defining a smaller diameter work disk and the other of said work disks defining a larger diameter work disk, a separate substantially ring-shaped stop provided for each such different diameter work disk, the ring-shaped stop provided for the smaller diameter work disk defining a smaller ring-shaped stop relative to the other ring-shaped stop provided for the larger diameter work disk defining a larger ring-shaped stop, and at least the ring-shaped stop provided for the smaller diameter work disk being fixedly secured to said machine housing.

2. The floor treating machine as defined in claim 1, further including means for detachably securing the larger ring-shaped stop for the larger work disk at the machine housing.

3. The floor treating machine as defined in claim 2, wherein the larger diameter ring-shaped stop comprises a stop ring member which surrounds the smaller ring-shaped stop.

4. The floor treating machine as defined in claim 3, wherein the larger ring-shaped stop is arranged to be supported at the smaller ring stop.

5. The floor treating machine as defined in claim 4, wherein the larger ring-shaped stop possesses a substantially pot-shaped configuration and has an end wall which is supported at the smaller ring-shaped stop.

6. The floor treating machine as defined in claim 5, wherein the larger ring-shaped stop and said machine housing have cooperating means for centering said larger ring-shaped stop.

7. The floor treating machine as defined in claim 6, wherein said centering means comprises said machine housing having holes, the larger ring-shaped stop having centering projections and plug-in pins provided at the end face of said larger ring-shaped stop, said centering projections engaging about the smaller ring-shaped stop, and said plug-in pins being insertable into said holes of the machine housing.
