Definitions

  • the present invention relates to a device which is connectable to a known liquid aspiration unit for cleaning flat surfaces such as glass panes, ceramic tiles, ceilings, walls, floors etc., by aspirating the washing liquid so that it is collected in an appropriate container of the aspiration unit.
  • devices which have an aspirating region arranged between two flexible rubber blades, both of which slide on the surface to be cleaned.
  • One of said blades has notches or discontinuities so that the collected liquid can flow toward said aspiration region.
  • the aim of the invention is to overcome the disadvantages encountered in the use of the known devices connectable to aspiration units for cleaning flat surfaces.
  • an object of the present invention is to reduce or to halve the work time, the effort of the operator and the power required for the operation of the aspiration unit.
  • the present invention provides a device which is active in two opposite directions of motion by virtue of a particularly effective and original solution which consists in providing, in the body of the device, two parallel rows of aspiration openings or intakes separated by a known rubber blade the elastic flexing whereof, assisting in both directions the movement of the accessory on the surface to be cleaned.
  • the blade causes, each time, the temporary closure of one row of intakes, whereby to allow aspiration only through the opposite row, which is on the rake side of the blade and above the region for collecting the liquid to be removed.
  • the device according to the invention similarly to other accessories for vacuum cleaners and liquid aspiration units, is shaped so as to define a chamber which is suitable for conveying toward the tubular handle, connected to the unit, all of the flows of material arriving from the aspiration intakes which are arranged, on the two sides of the rubber blade, along the entire operating front of the device.
  • the device is composed of:
  • the rubber blade A which is identical to those already mounted in glass-cleaning implements and liquid aspiration machines, has a toroidal enlarged edge for securing in the blade holder element B and, more specifically, between the internal recesses or ridges 1 which delimit, together with said blade, the individual aspiration intakes.
  • Said recesses or ridges 1 are shaped so as to prevent the downward extraction of the blade A, since said blade, which is inserted longitudinally in the blade holder, is secured thereat by the pressure of the blade presser C which is in turn pushed by the cover D.
  • the blade holder B has, inside it, two conical or cylindrical raised portions 4 which are preferably provided with a threaded metallic bush and are in any case suitable for receiving the screws 6 which fix the cover D to the blade holder B.
  • the element C or blade presser which extends along the entire length of the blade holder B, has:
  • the cover D is advantageously defined monolithically, together with the tubular handle 7 which, as in known vacuum cleaner accessories, acts as short handle and is also complete with couplings for insertion on rigid or flexible tubes which connect the device to the aspiration unit.
  • Said cover has an edge shaped so as to provide a sealed coupling with the blade holder B.
  • the cover is provided, in an upward position, with the holes 5 for the screws 6 for fixing to the blade-holder and with a series of seats 3.
  • the seats 3 are through holes or blind holes and are in any case shaped for accommodating the conical raised portions 2 of the blade presser C.
  • the blade presser C is maintained in the correct position by the engagement of the raised portions 2 in the seats 3, and by the ridges 1 of the blade holder B, between which it wedges.
  • the shape imparted to the three elements B, C and D is also a function of manufacturing requirements, since they are advantageously manufactured by injection molding in ABS, PVC or another thermoplastic material.
  • the entire device can be easily inspected and cleaned after removing the only two assembly screws 6, whereas in order to longitudinally extract or insert the blade A it is sufficient to loosen said screws without disassembling the entire device.
  • the upper element F is manufactured monolithically together with the tubular handle 15 which, complete with appropriate known couplings, can be inserted in a rigid or flexible duct for connection to the liquid aspiration unit.
  • the loosening of the screws 14 allows the longitudinal extraction and replacement of the blade A, whereas the complete removal of said screws and the consequent separation of the two elements allows the inspection and complete cleaning of the device.
  • the rubber blade is rigidly associated exclusively in its toroidal region, since its entire planar portion, or most of it, is free to flex, in one direction or the other, depending on the sliding for cleaning and until it rests against one of the two rows of intakes.
  • the mounting of the rubber blade furthermore allows said blade to protrude, at the two ends of the device, enough to pass so as to lightly contact the raised edges which delimit a glass pane or other surface to be cleaned.
  • the device according to the invention is susceptible to modifications or variations, also in relation to the dimensions.
