Definitions

  • a cleaning device of this type comprises an elongated handle, a supporting frame removably and pivotally connected to an end of said handle, and a web of fabric stretched over said supporting frame and kept taut which is used to clean surfaces such as floors and the like.
  • the supporting frame is collapsable or otherwhise adapted to be at least partially dismounted.
  • the supporting frame generally comprises an assembly of suitably linked components adapted to assume a generally coplanar configuration in which the fabric web is stretched, and a collapsed or angled configuration in which the components are still joined together but not forming a rigid frame so that the fabric web can be easily washed, rinsed or replaced.
  • the fabric web (or cotton cloth) is generally provided with two opposed pockets or engagement cavities into which are fitted the ends of the supporting frame.
  • the known cotton brooms are different from each other in respect to the construction of the supporting frame keeping taut the fabric in the cleaning operations.
  • This frame must allow for an easy and quick assembly and disassembly to wash the fabric web and to replace the same when it is worn out.
  • the known supporting frames are of plastic material and comprise two elongated members or arms pivotally joined together, at least one of them having an extension that extends beyond the pivoting axis in order to partially overlap the other when the frame reaches the coplanar configuration.
  • the parts to be superimposed are of reduced thickness, also to save material and to get a support which is not too heavy.
  • constraint or locking means are provided that prevent the undesired collapsing of the frame, such means being preferably located in the overlapping area and at the end portion of the above mentioned extension.
  • Such means are usually devised for an easy assembly and disassembly (i.e. such as to be actuated by a single hand or a foot).
  • DE-U-87 06 126 discloses a cleaning device comprising an elongated handle, a supporting frame removably and pivotally connected to an end of said handle, and a web of fabric stretched over said supporting frame, said supporting frame comprising two elongated members or arms of plastic material and pivotally connected together, and locking means to block said arms in a coplanar configuration and to disengage them, at least one of said arms providing for an extension that extends beyond the pivoting axis in order to partially overlap the other arm when the frame reaches the coplanar configuration.
  • the arms are pivotally connected together by separate pins to be fitted into pairs of holes provided in both arms and the locking means comprises a projection secured to one of the arms and a complex-shaped pawl including a return spring secured to the other arm.
  • the invention consists of a cleaning device comprising an elongated handle, a supporting frame removably and pivotally connected to an end of said handle, and a web of fabric stretched over said supporting frame, said supporting frame comprising two elongated members or arms of plastic material and pivotally connected together, and locking means to block said arms in a coplanar configuration and to disengage them, at least one of said arms providing for an extension that extends beyond the pivoting axis in order to partially overlap the other arm when the frame reaches the coplanar configuration, characterized in that said arms are pivotally coupled together by snap fitting comprising pivot pins integrally formed with one of said arms and pivot seats formed in the other of said arms, and in that said locking means are provided by snap fitting comprising engagement pins integrally formed with the other of said arms and pivot seats formed in said one of said arms.
  • the supporting frame is completely of plastic material, no metal element being required (not even for the pins), and such frame comprises only three members, namely two arms and a pawl, wherein the coupling between the pivot pins (that are molded integer with the arms) and the seats thereof takes place by snap fitting.
  • the locking means to keep coplanar the two arms (in the working step) is carried out by means of clip or snap fitting engagement, by applying a proper force to overcome an initial interference of the parts to be connected.
  • a pawl of the type having a lever with a central fulcrum or pivot point, which applies a force acting along an opposite direction with respect to the one applied initially to set the assembly flat.
  • the supporting frame of the invention comprises two elongated member or arms, 1 and 2 that in use are assembled together.
  • the arms 1 and 2 are adapted for a partial overlapping, with the parts interpenetrating with each other thanks to proper thickness reductions.
  • the arm 2 provides for a portion of reduced width from which a pair of opposed pivot pins 3 protrude, and a reduced thickness portion marked by 7 in the middle area thereof.
  • the arm 2 On the underside of the reduced width portion, the arm 2 carries opposed seats 5, each formed as a longitudinally opened sleeve of circular cross section, provided for cooperating with a corresponding pair of engagement pivot pins 4 on arm 1.
  • two projections 8 are present onto which the user pushes in order to force the seats 5 into engagement with the above mentioned pivot pins 4.
  • the arm 2 further carries a shoulder 9 for an axis 10 over which it is to be applied an articulated member (not shown) for the connection to the shaft of the handle (also not shown).
  • the arm 2 further provides for a C shaped projection 17 to which can be anchored a tape connected to the cotton web 19.
  • the arm 1 provides for a middle opening or window 13 in which are arranged seats 11, formed as grooves with a circular cross section inner portion and a flared outer portion, adapted to engage the pivot pins 3.
  • the arm 1 further provides for a pair of opposed engagement pivot pins 4 protruding into the window 13.
  • pivot pins 3 The shape of pivot pins 3 is such that it can be housed into the seats 11 after a moderate resilient deformation to overcome an interference between them, and the same applies also to the snap fitting between pivot pins 4 and the seats 5.
  • a central pivot pin 6 is further provided on arm 1, cooperating with the window 13 and the reduced thickness portion 7 for positioning a pawl member 14-16 that will be now illustrated with reference in particular to Figures 15, 18, 19 and 20.
  • Such pawl member is shaped like a lever with an intermediate fulcrum (at 16) and a flat round portion 15 adapted to be pressed by the user's foot, and an actuating end 14.
  • the pawl member 14-16 is received in the reduced thickness portion 7 and in the window 13, and is hinged at pivot pin 6 of arm 1.
  • the pawl member 14-16 is initially applied to the arm 1 by forcing the seat 16 over the pin 6, and then the arms 1 and 2 are mutually positioned in such a manner that the seats 11 lay over the pivot pins 3. By pressing together the arms, the seats are resilientely deformed and the pins are received within them so as to form an articulated frame as can be seen in Fig. 16.
  • the cotton broom can be dipped into a basin containing water and squeezed without being touched by the hands.
