Definitions

  • the invention concerns a cleaning device comprising a box-like structure able to be moved on a surface to be cleaned and to contain at least a brush with a horizontal axis of rotation which, in cooperation with suction means, is able to remove dust and dirt from any surface whatsoever.
  • the brush can be removed from the box-like structure to allow the user to replace it according to the specific surface to be cleaned or when the brush is worn.
  • the state of the art includes cleaning devices equipped with a box-like structure provided at the upper part with a steering handle and at the lower part with a brush with a substantially horizontal axis of rotation.
  • the brush In cooperation with conventional type suction means, the brush is able to remove the dust and dirt from any surface whatsoever.
  • the state of the art includes, for example, a cleaning device which instead of being equipped with a single brush of a length a little less then the width of the box-like structure, is equipped with two half-brushes, each of which is able to be coupled to a respective end of a horizontal shaft able to receive rotational motion in correspondence with a median segment wherein a transmission belt turns, connected to an electric motor.
  • the presence of a transmission belt located between the two half-brushes entails both a reduction in the usable working surface and also the possibility that the dust and dirt can compromise the grip of the belt on the horizontal shaft or even reach the electric motor or the other transmission organs, with consequent problems of malfunctioning.
  • the main purpose of the invention is to achieve a cleaning device equipped with at least an interchangeable brush with a horizontal axis of rotation, wherein the brush can be replaced by the user very simply and quickly and without using specific tools.
  • Another purpose of the invention is to provide a cleaning device wherein the transmission of rotational motion from the motor to the brush occurs without imbalances of forces and in such a fashion as to exploit the maximum power supplied by the motor.
  • a cleaning device comprises, like convention cleaning devices, a box-like structure able to be moved, by steering means commanded by the user, on any surface to be cleaned and able to contain at least a brush with a horizontal axis of rotation.
  • the brush is able to be selectively coupled axially to a substantially horizontal rotation shaft, driven by a motor.
  • the box-like structure is laterally equipped with an aperture, axially aligned with the rotation shaft and able to be selectively closed by a closing element equipped with coupling means for a first end of the brush.
  • This characteristic allows both to use brushes which extend for a substantial part of the width of the box-like structure and also to simplify and accelerate the operations to couple and remove the brush.
  • the coupling means are able to allow to remove the brush from the closing element; in this way, the same closing element can be used for a plurality of different brushes.
  • the coupling means are able to allow the brush to move vertically with respect to the surface to be cleaned.
  • constraining means commanded by the user are provided to maintain the closing element coupled with the aperture of the box-like structure.
  • the constraining means can be achieved with any mechanism or device able to couple the closing element to the aperture of the containing structure in a simple, quick and secure manner.
  • the constraining means comprise first clamping means provided on the closing element and second clamping means provided on the box-like structure, the first and second clamping means being able to interact.
  • the first clamping means, or the second clamping means comprise one or more notching elements.
  • the notching elements have a working position wherein they are able to protrude with respect to the outer perimeter of the closing element to interfere with a corresponding segment of the perimeter edge of the aperture provided on the box-like structure.
  • the command means are able to selectively move each notching element towards the inside of the closing element into a position of non-interference with the perimeter edge of the aperture of the box-like structure.
  • the brush is able to receive rotational motion from the rotation shaft in correspondence with an inner coupling segment thereof.
  • This characteristic allows to increase the active surface of the brush, since there are no belts or similar on the working surface, and also to prevent dirt and dust from reaching the motion transmission members.
  • the inner coupling segment is provided in a substantially median position of the brush, thus allowing a better distribution of the forces transmitted by the motor.
  • the inner segment is equipped with first rapid coupling means able to be selectively connected to second rapid coupling means provided on the rotation shaft.
  • FIG. 1 The attached Figures show a partial view of a cleaning device 10 according to the invention which comprises a box-like structure 11 able to contain a brush 12, cylindrical in shape and able to be selectively coupled with a horizontal shaft 20 connected, as will be explained later in more detail, to a motor 13.
  • the box-like structure 11 is made in two parts coupled together; a lower part, or bottom, 11a is provided with an aperture 16, from which the brush 12 is able to partly protrude in order to brush the surface to be cleaned, and an upper part, or cover, 11b.
  • the brush 12 has a substantially conventional outer conformation and an inner conformation defined by four segments, respectively first 12a, second 12b, third 12c and fourth 12d, with a progressively decreasing transverse section (Fig. 6).
  • the third segment 12c provided in a substantially median position of the brush 12, is equipped with a radial element 33 through which the brush 12 is able to receive motion generated by the motor 13.
  • the fourth segment 12d is able to be coupled, as will be explained later in more detail, to a closing element 21 able to cooperate with an aperture 35 provided on one side of the box-like structure 11 in a position axially aligned with the rotation shaft 20.
  • the motor 13 is equipped with a shaft 36 onto which a first pulley 17 is keyed, connected by means of a toothed belt 39 to a second pulley 19 solid with a first end of the shaft 20.
  • the length of the shaft 20 is substantially half the overall length of the brush 12 and is coupled rotatably to a hollow cylindrical extension 14 of a supporting element 37 (Fig. 5).
  • the cylindrical extension 14, as shown in Figs. 3 and 5, is internally equipped with two bearings 15 which allow the shaft 20 to rotate with minimum friction around its longitudinal axis.
  • a cylindrical element 17 is coaxially coupled, provided with a disk 17a able to couple with the first segment 12a of the brush 12.
  • the shaft 20 is also equipped, on the end opposite that where the pulley 19 is keyed, with a coupling element 18 able to transmit the rotational motion to the brush 12.
  • the coupling element 18 comprises a first cylindrical part able to couple with the third segment 12c of the brush 12 and a second part consisting of two protrusions 18a defining a conformation substantially like a fork able to enclose the radial element 33 of the brush 12.
  • the cleaning device 10 is equipped with a constraining assembly 40 which allows to maintain the closing element 21 coupled with the aperture 35.
  • the constraining assembly 40 comprises a clamping mechanism 38 provided on the closing element 21, able to be selectively dis-activated by the user by means of a lever 22 coupled with the box-like structure 11.
  • the closing element 21 is equipped on the inner face with holes and grooves which allow to couple with a plate 19 which is equipped with guide elements 29 which allow to couple with a vertically movable element 26.
  • the element 26 is equipped with a pin 30 onto which a radial bearing 31, able to be made solid with the fourth segment 12d of the brush 12, is able to be keyed.
  • the sliding of the element 26 in the guide elements 29 allows the brush 12 to move vertically with respect to the surface to be cleaned thanks to the fact that the supporting element 37 is able to rotate in a controlled fashion around the shaft 36 of the motor 13.
  • the device 10 according to the invention can also be of the type equipped with a brush 12 which cannot be adjusted in height; in this case the pin 30 will be solid with the plate 19 and the supporting element 37 will be solid with the lower part 11a of the box-like structure 11.
  • the clamping mechanism 38 is able to be positioned between the closing element 21 and the plate 19 and comprises two specular fins 27, movable horizontally, and an element 28 shaped like an upside down U and movable vertically.
  • the two fins 27 are coupled together by means of a compression spring 32 which tends to keep them distanced from each other.
  • the outer part of the fins 27 is able to interfere with the facing edges 35a of the aperture 35 to constrain the closing element 21 to the box-like structure 11.
  • the facing edges 35a of the latter are able to position themselves between the closing element 21 and the fins 27 so that the group consisting of the brush 12 and the closing element 21 is axially constrained to the box-like structure 11.
  • the lever 22 by means of an eyelet 23 made at a first end thereof, is able to pivot on the lower part 11a of the box-like structure 11; the lever 22 is equipped at a second end with a tooth 24 able to cooperate with the clamping mechanism 38 and, in a substantially median position, with a disk 25 able to protrude from an aperture 34 provided on the upper part 11b.
  • removing the brush 12 is extremely simple and quick since the user only has to press the disk 25.
  • the two fins 27 are released from the facing edges 35a of the aperture 35 allowing to remove, from the aperture 35, the closing element 21 and the brush 12 associated therewith.
  • the radial element 33 is released from the element 28 without any further external interventions being required on the part of the user.
  • the shaft 20 is automatically constrained to the brush 12, and in particular the element 28 to the radial element 33, without further external interventions being required on the part of the user.
  • the closing element 21 can be externally equipped with a handle or other gripping element able to facilitate the operations to remove/insert the brush 12 from/into the box-like structure 11.
  • the element 28 is able to cooperate with a spring, or other elastic element, able to automatically push the group consisting of the brush 12 and the closing element 21 towards the outside of the box-like structure 11 when the disk 25 of the lever 22 is pressed by the user.
  • bearings 15 and 31 can be replaced by disks made of material with a low friction coefficient.
  • the closing element 21, as well as the clamping mechanism 38 may have a command element with the same function as the lever 22.
  • clamping mechanism 38 can be made in different ways and the lever 22 can be replaced by any other command element, chosen according to the type of mechanism 38 used.
  • the element 18 can be of a different shape from that shown here, for example of the type comprising three or more extensions 18a able to cooperate with the same number of radial elements 33.
  • the third segment 12c of the brush 12 can be equipped with a diaphragm provided with apertures into which the extensions 18a, appropriately shaped, of the element 18 are able to be inserted.
  • cleaning devices 10 equipped with two or more brushes 12 coupled at a first end with the same closing element 21 or with respective closing elements 21.
  • the transmission of the rotational motion from the motor 13 to the shaft 20 can be achieved with any kinematic chain of a different type than that shown here.
