Definitions

  • the present invention relates to improvements in the cleaning devices known as "cotton brooms”.
  • a cleaning device of this type comprises an elongated handle, a supporting frame removably and pivotally connected to one end of said handle, and a web of fabric stretched over the supporting frame and kept taut which is used to clean surfaces such as floors and the like.
  • the cotton brooms presently sold are different from each other in respect of the construction of the supporting frame the surface of which can be made up by two or more cooperating portions, and in respect of the constraints keeping the parts (forming such surface) in a coplanar relationship during the operation thereof, or disengaging them from the coplanar configuration in order to allow for the assembly, the washing or disassembly of the fabric.
  • the known supporting frames for cotton brooms have a number of disadvantages in that they are of complex and costly construction, require several components some of which are metal parts, and are prone to jamming or breaking.
  • DE-A-3 923 859 upon which the preamble of claim 1 is based discloses a cleaning device comprising a three-part supporting frame removably and pivotally connectable to an elongated handle, with a web of fabric being stretched over the supporting frame.
  • the arms of such device are simmetrical and U-shaped with outwardly protruding end pins that can be fitted into a plurality of seats formed in a central member through a manual elastical deformation of the arms.
  • the arms are further to be disengaged from the central member when a web of fabric is to be stretched over or removed from the supporting frame.
  • a cleaning device comprising an elongated handle, a supporting frame removably and pivotally connected to one end of said handle, and a web of fabric stretched over said supporting frame, said supporting frame comprising two elongated members or arms and snap locking means to maintain said arms in a coplanar configuration and said fabric stretched thereon, said supporting frame further comprising a central flat member equipped with an attachment for said handle to which member said arms are pivotally connected, said two arms and central flat member being moulded from a plastic material, characterized in that the first of said arms is provided with two side extensions with ends of reduced thickness and with a pair of inwardly projecting pins; that the second of said arms is provided with two extensions with side portions of reduced thickness and adapted to abut against and cooperate with the ends of said first arm when the supporting frame is in the coplanar configuration.
  • the solution proposed for the supporting frame according to the invention aims to obtain the maximum of functionality together with a simple construction and use, and at competitive costs.
  • the whole construction can be of a plastic resin material (included the pins) without any metal component.
  • the supporting frame is made up by three parts, hinged together, and more precisely, two side arms and a central flat member equipped with an attachment for the handle.
  • the above parts are bound to be firmly maintained coplanar during the operation of the device, whereas they are released from the coplanar arrangement (so that the outer arms can get an angled position through a rotation about the pivot pins by which they are connected to the central flat member) when the "fabric" is to be washed, rinsed, squeezed or replaced.
  • the supporting frame of the invention comprises two elongated members or arms, 1 and 2 and a central flat member 3 that in use are assembled together. All the three members are formed by moulding of a suitable plastic material. As it is clearly shown in the drawings, the three members are adapted for a partial overlapping or mating, with the parts interpenetrating with each other thanks to proper thickness reductions.
  • the central member 3 as it is best seen in Figs. 12 and 13, is a generally rectangular flat body of plastic material provided with a first pair of outward protruding coaxial pivot pins 11-11 and with a second pair of outward protruding coaxial pivot pins 12-12 that are shorter than the former, all the pins being orthogonal to the longitudinal axis of the member.
  • the portion of the body 3 carrying the pins 11-11 is wider than the portion carrying the pins 12-12.
  • the free end of the narrower portion provides for a strip 32 of reduced thickness, and two inclined side surfaces 34 are provided at about the middle of the member 3.
  • the flat member 3 is moulded as a single plastic piece simultaneously with all the above illustrated components.
  • the arm 1 has a general flat configuration with a central recess 7 on one face (the upper one when the device is in use) and two side extensions 29.
  • a squared opening or window 13 is formed in the recess 7, approximately at the middle of the arm 1.
  • a pair of seats 17 are formed for a device that secures the fabric to the supporting frame, as will be illustrated with more details later. Also these seats are formed as grooves with a circular cross section inner portion and a flared outer portion and are adapted to receive pins through plastic deformation.
  • Arm 1 is further provided with at least a pair of pins 4 located in the recesss 7 and adapted to cooperate and engage with the above mentioned seats 5 of the member 3 to form a snap connection or clip constraint.
  • a transverse pin 6 extends within the recess 7, in correspondence of the window 13, and a pair of seats 11'-11' are formed in the extensions 29.
  • Such seats are formed as grooves with a circular cross section inner portion and a flared outer portion and are adapted to receive the above mentioned pivot pins 11, 11 of the central flat member 3.
  • the ends 30 of the extensions 29 are of reduced thickness and cooperates with similar ends 31 of the arm 2 to form abutment means as will be illustrated later.
  • the arm 2 has a general flat configuration with two side extensions 28. On the face that is the upper one when the device is in use, near one end thereof, a pair of seats 17 are formed that are similar and for the same purpose of those provided on the arm 1.
  • a pair of seats 12'-12' are formed in the extensions 28. Such seats are formed as grooves with a circular cross section inner portion and a flared outer portion and are adapted to receive the above mentioned pivot pins 12, 12 of the central flat member 3.
  • Two side portions 31 of the extensions 28 are of reduced thickness and cooperates with the corresponding portions 30 of the arm 1 to form abutment means. Further two inclined surfaces 35 are provided for at the end of the extensions 28 for cooperating with the above mentioned two inclined side surfaces 34 of member 3. Finally, a step portion 33 is provided between the extensions 28 to abut the strip 32 of reduced thickness of the member 3.
  • the device of the invention further comprises a member for the quick release of the snap connection 4-5.
  • This member is in form of a pawl 14-15, illustrated in Figs. 4 and 5, is shaped like a lever and received in the reduced thickness portion 7 and in the window 13.
  • the pawl is pivoted in correspondence of an intermediate fulcrum, at 16, to the transverse pin 6 of the arm 1.
  • the arm 1 Upon acting onto the pawl 14-15, the arm 1 ceases to be rigidly integral with the central flat member 3, and at the same time ceases the action of the extensions 30 upon the reduced thickness areas 31 of the arm 2.
  • the positioning of the pins 11, 11 and 12, 12 and the length of the portions of both arms 1 and 2 extending beyond their own pins are chosen in such a manner that when switching from the coplanar position to the angled one and viceversa, there are prevented jamming or mutual encroachment that might lead to a breaking of the supporting frame structure.
  • Fig. 28 illustrates a partially collapsed configuration in which after the release of snap coupling 4-5, the arms 1 and 2 hinged at 11 and 12 to the central flat member 3 assume an angled position, and can be further rotated to reach the configuration shown in Fig. 29.
  • the central flat member 3 is raised from the floor so that the arms 1 and 2 drop into a vertical position, and the fabric 19 secured by tapes 18 to clamping means at the ends of arms 1 and 2, hangs loose and can be washed, squeezed and rinsed, or replaced if necessary.
  • Figs. 30-32 illustrate the construction of the means for clamping the fabric 19 to the supporting structure.
  • Such means comprises a plate 21 located under a two-arm eccentric lever 20 pivotally mounted between the seats 17.
  • a tape 18 provided at each end of the fabric 19 is led under the plate 21 and tensioned by pressing the eccentric lever 20.
  • the plate 21 prevents any displacement of the fabric, allowing only the fabric compression during the use of the cleaning device.
  • Fig. 33 is an exploded partial cross section view of the attachment for securing the broomstick 48 to the flat central member 3, whereas Fig. 34 is a partial side view of Fig. 33.
  • the attachment comprises a forked member 40 gripping with the seat 43 the shaft 10 that is carried by the flat member 3.
  • the forked tip 44 of the broomstick holder 46 engages a pin 41 in the member 40 and the broomstick 48 is received and blocked in the holder thanks to a threaded bush 47 that is screwed on the externally threaded holder 46 acting as a chuck-wise conical clamping.
  • a plastic moulded clip 50-51 which is better illustrated in the three views constituting Fig. 35.
  • Such component is a single piece shaped like an interrupted ring portion or annulus 50 with a diametrally extending pin 51 that passes through both the holder 46 and the broomstick 48, both provided with through holes 52 and 49.
  • the pin 51 acts like a peg and the ring portion 50 prevents the pin 51 from coming out from the broomstick.
