Problems solved by technology

[0004] However, the rotating brushes disclosed in US1497921 and US4074385 cannot clean the so-called "transitions" obtained in all cases, i.e. the connection areas between adjacent tiles or briquettes; moreover, the cleaning of irregular surfaces is even less satisfactory , due to the difficulty of the bristles to reach all the tips of irregular surfaces, and the tendency to strike on irregular surfaces during tool rotation

Embodiment Construction

[0026] exist figure 1 1 denotes a tool according to the invention as a whole having a body 2, for example substantially cylindrical, forming holes (not shown) on a surface 3, into each of which a tuft of natural or artificial bristles 5 is inserted middle. The holes are arranged on the surface 3 along one or more paths, for example along a helical path, or along a plurality of possibly concentric circumferences, or along a plurality of polygonal paths. The axis of each hole is inclined to the vertical plane of said surface in a plane substantially tangential to said path, so that a tuft of bristles inserted therein is correspondingly inclined.

[0027] The axis inclination of each hole a( Figure 4 ) can vary between a first minimum and a first maximum in a first part of the path, i.e., a first helical or circumferential arch, and in a second part of the path from the first maximum value changes towards a second minimum value, changes from said second minimum value to a sec...

Abstract

A tool (1; la) for cleaning surfaces, comprising a body (2; 6) with a substantially cylindrical shape, on a face of which (3;7) there are distributed along at least a path (4) clumps of bristles (5; 8; 9) inserted into corresponding holes made on said face (3;7), characterized in that the axis of each of said holes is inclined in relation to a perpendicular to the surface of said face (3; 7), on aplane substantially tangential to said at least a path (4), or on a plane substantially radial to said path, or on both said planes.

Description

technical field [0001] The present invention relates to a rotary tool, such as a brush, for cleaning floor surfaces or floor-like surfaces, suitable for use in machines for cleaning floors. Background technique [0002] In the prior art, known tools for cleaning floor surfaces comprise a circular support on which tufts of bristles of synthetic, natural, abrasive etc. material are arranged. US1497921 discloses a rotating brush comprising a block and a plurality of bristle bundles fixed to the block and protruding from its front surface, the bristles overcoming the effect of rotating Centrifugal force on the brush is angled inwardly at an angle of less than 90 degrees relative to the front surface of the mount and the bristles are also angled rearwardly relative to the direction of rotation of the brush. The bristles are angled backwards with respect to the direction of rotation of the brush to reduce vibrations when the bristles hit the surface to be cleaned, the angle of in...
