It is known to use piassava-type brushes to remove dry contaminants such as snow, sand, soil, glass shards and the like from sidewalks and machine shop floors. It is also known to use the aforementioned brushes or scrapers, which are sheet metal or rubber-coated sheet metal, to remove wet contaminants such as manure from the floors of barns and pig farms.

The aforementioned piassava-type brushes, however, commonly incorrectly referred to as piassava currency, comprise a flat, rectangular bristle wood to which piassava bristle bundles are attached. When the brush is used to remove wet contaminants, the stem absorbs these through the end of the stem and soon rots, as does the brush wood surrounding the stem hole. This often happens before the bristles are worn out, which is why both the brush and the shaft must be discarded prematurely.

There is also no means of combining the above-mentioned cleaning elements per se, but where these have had to be used alternately, two or three different means have had to be kept on hand.

The present invention relates to a device which in itself includes the above-mentioned elements and functions, and in which the brush does not have to be discarded until its bristles have worn out and can be easily replaced.

The device according to the invention has the shape and the features which appear from the appended claims.

The invention is illustrated in the accompanying drawing, in which:

Fig. 1 shows a top view of a structural form of the device according to the invention;

Fig. 2 shows the same device in section II-II of Fig. 1

along;

Fig. 3 shows a part of the rubber plate 11;

Fig. 4 shows the flange 3 seen from below.

The arm 1 is preferably provided at its lower end with a circular flange 3 fixedly connected thereto so that the angle between the arm 1 and the flange 3 is the same as that formed by the arm hole of the bristle brush 4 with the upper surface of the brush tree 4. The side of the flange 3 facing away from the arm 1 is provided with a pin 5 which starts from the center of the flange in the opposite direction to the arm 1 and which, by its position and dimension, can be inserted into the above-mentioned arm hole so as to protrude below the bristle tree 4. The protruding part of the pin 5 is provided with an axial slot adapted to receive a wedge 6 which can fasten the brush wood 4 firmly against the lower surface of the flange 3. The side of the wedge 6 opposite the bristle wood 4 is preferably provided with sawtooth-shaped teeth 13 which, when the wedge 6 is inserted, engage the bristle wood 4 and prevent the wedge 6 from coming loose and pounding away. The pin 3 is provided with at least one and preferably two wedge-shaped, sharp-edged radial projections 13, which are firmly attached to the flange 3 at their upper end and are preferably diametrically arranged. The projections 13 are preferably in the shape of a rectangular triangle in the radial longitudinal section and cut when the wedge is inserted into the edges of the hole in the bristle wood 4 so that the bristles cannot bend with respect to the flange 3.

It has proved advantageous to place a rectangular sheet metal plate 7 with a projection between the flange 3 and the bristle wood 4.

Claims (8)

A means for removing dry and wet contaminants, in particular from sidewalks and floors in machine shops and barns, comprising a stem (1) and a brush (2), preferably of the piassava type, the stem (1) or a separate holder coaxial with it being provided with a flange (5), the flat lower surface of which forms an angle with the longitudinal axis of the shaft (1) equal to the angle formed by the flat upper surface of the bristle wood (4) with the shaft hole in the bristle wood (4). a coaxial pin (5) coaxial with the shaft (1), positioned and dimensioned so as to be able to be placed in the shaft hole of the bristle wood (4) and having a diametrical axial slot (18) projecting from the lower surface of the bristle wood (4), adapted to receive a wedge (6) for fixing the bristle wood (4) against the lower surface of the flange (3), characterized in that a position is arranged between the flange (3) and the upper surface of the bristle wood (4) u a sheet metal plate (7) substantially in the form of this upper surface, the longitudinal side of the plate (7) facing the obtuse angle between the shaft (1) and the bristle wood (4) extending beyond the bristle wood (4) and having a bristle wood (4) ) a hole corresponding to the shaft hole and at least one V-shaped notch starting from said hole in the plate (7), the edges of which diverge towards the hole and that at least one wedge-shaped projection (13) connected to both the flange (3) and the pin (5) is in position and dimensioned so as to fit at the flange (3) without being pressed into the notch of the plate (7). Device according to Claim 1, characterized in that the projection (13) or projections have a V-shaped blade which is directed away from the pin (5). Device according to Claim 1 or 2, characterized in that the cross-sectional surface of the projection via the longitudinal axis of the blade and the arm (1) of the projection (13) is rectangular triangular. 3 60962 boiled 15 corresponding V-shaped notches. This sheet metal plate 7 is provided with a part 8 projecting along the lower longitudinal side of the brush wood 4, which is most preferably bent downwards so that its outer part La forms an angle α of 150 ° to 165 ° with the main part of the sheet metal plate 7, which is more suitably 145 °. Along the free edge of this part 8, a sheet metal strip 9 is placed, which can be pressed against the rubber plate 11, for example by means of screws 10 and wing nuts 17, and thus hold it in place. This plate 11 is preferably provided with slots 18 open at its upper longitudinal side at the screws 10 and with slots 18 perpendicular to this longitudinal side. removal from sidewalks, external stairs and the like is used - a piassu wax brush 2 in the usual way. In this case, the strong attachment of the brush 2 provided by the wedge 6 gives a good result. In the case of wet dirt, it is often advantageous to use the tool first with the rubber plate 11 facing downwards and after most of the dirt has been pushed out, continue cleaning with brush 2. In the case of snow removal it is also generally advantageous to start with rubber sheet 11 and continue with brush 2 When the snow is hard or in the case of ice, it may often be appropriate to start by hitting the ice and snow off with your teeth 14. When removing manure from the barns, it is usually preferable to start with a rubber plate and continue with a brush 2 if necessary. possible within the scope of the invention. Device according to claim 1, characterized in that the protruding part (8) of the sheet metal plate (7) is bent downwards towards the bristles so that its outer part forms an angle α with the main part of the sheet metal plate (7) of 130 ° to 165 ° and 145 ° is most suitable. Device according to Claim 1 or 4, characterized in that a sheet metal strip (9) is arranged along the free edge of the projecting part (8), which can be pressed against the rubber plate (11), for example by means of screws (10) and wing nuts (17), and thus holding the disc in place. Device according to Claim 5, characterized in that the rubber plate (11) is provided at the screws (10) with notches (12) directed perpendicular to the longitudinal side above it. Device according to Claim 6, characterized in that the projections (13) have two projections and are arranged diametrically. Device according to Claim 1, characterized in that the sheet metal plate (7) is provided with teeth (14) projecting from the plane of the plate (7) at least along one of its sides. 5 60962
