DESCRIPTION:
BRIEF SUMMARY
The invention relates to a floor-sweeping machine consisting of a housing with a revolving brush which is mounted rotatably therein and which can be driven by means of running wheels projecting from the underside of the housing.
In this known floor-sweeping machine, the revolving brush has in its two ends bearing bores for bearing journals. Each bearing journal is retained on a respective fastening plate, the fastening plate being screwed to the outer side of the housing wall of the floor-sweeping machine. The bearing journal passes through a perforation in the housing wall of the floor-sweeping machine and engages into the bearing bore of the revolving brush. When the revolving brush is assembled, it first has to be inserted into the housing of the floor-sweeping machine, and then the bearing journal has to be inserted through the perforation in the housing wall and introduced into the bearing bore of the revolving brush. Subsequently, the fastening plate of the bearing journal then has to be screwed to the outer side of the housing wall. Assembly of the floor-sweeping machine and even replacement of the revolving brush are therefore very complicated.
The object on which the invention is based is to provide a floor-sweeping machine of the type explained in the introduction, in which such disadvantages are avoided and the revolving brush can be assembled and removed simply and quickly.
This object is achieved, according to the invention, due to the fact that the revolving brush is mounted rotatably by means of two bearing clasps which engage at its ends and which each have a bearing receptacle for the associated bearing end of the revolving brush, and the bearing clasps are themselves retained by securely positioned clamping onto housing parts. As a result, assembly of the revolving brush is simplified in a simple way, since only the two bearing clasps, together with the revolving brush located between them, have to be clamped onto housing parts by simple attachment.
The bearing clasp can have, for the associated bearing end of the revolving brush, a tubular bearing receptacle for attachment onto the cylindrical bearing end. Because of this, the two bearing clasps can be attached onto the bearing ends of the revolving brush in an especially simple way, a reliable rotatable mounting of the revolving brush in the bearing clasps being achieved.
The cylindrical bearing end of the revolving brush can be formed by an offset projection of a pinion which is provided on the revolving brush and which is drive-connected to the running wheels. As a result, the cylindrical bearing end of the revolving brush is formed, in a simple way, by an offset projection of a pinion which is present, in any case, for the drive connection of the revolving brush to the running wheels.
The bearing clasp can be formed by an approximately U-shaped clamp made of spring steel and can be attached frictionally by means of the two legs of the U-shaped clamp onto a downwardly directed wall part of the housing. As a result, the bearing clasp can be fastened in an especially simple way to the downwardly directed wall part of the housing, since the approximately U-shaped clamp consisting of spring steel merely has to be attached to the downwardly directed wall part by means of its two legs, the two legs resting frictionally against the sides of the wall part located between them.
The approximately U-shaped clamp forming the bearing clasp can have the shaped-on tubular bearing receptacle on the inner side of one leg, whilst the second leg is provided, for passage of the bearing receptacle, with a cut-out portion starting from its free end. Because of this, the tubular bearing receptacle is shaped on one leg of the approximately U-shaped clamp in a simple way, which results in simple production being achieved. The tubular bearing receptacle extends through the gap between the two legs, so that less room is taken up for the tubular bearing receptacle.
The leg of the approximately U-shaped clamp which has the tubular bearing receptacle can rest by m
