Definitions

  • This patent concerns cleaning household appliances and in particular it concerns accessories for vacuum cleaners.
  • Household vacu ⁇ rh cleaners. gerierically comprise aff exterisibleror modular pipe with a handle at the end of which various accessories, a hose connected to said handle and the vacuum cleaner body are applied. A suction fan and a bin to collect the dirt are located inside the body of the vacuum cleaner.
  • the known vacuum cleaners are usually provided with an accessory for floor and rug or carpet cleaning, which is said nozzle unit.
  • the nozzle unit consists of a substantially rectangular and flat structure provided with a coupling on its upper part in which the suction pipe with the vacuum cleaner handle is fastened by means of a suitable fitting.
  • the lower part of the nozzle unit hosts some brushes, usually at the front and on the back, to clean smooth floors such as wood or tiles. Such brushes can be retracted so as to disappear into the structure of the nozzle unit to allow a better cleaning of rough surfaces such as rugs and carpets.
  • nozzle units are coupled to the pipe with handle of the vacuum cleaner through an articulated joint formed by two pivotally attached parts: the first part allows tilting the entire articulated joint by a few dozen degrees along the vertical front-rear plan while the other corner- shaped part allows tilting the pipe with handle sideways - left and right - with reference to the first part of the articulated joint.
  • the known nozzle units have the disadvantage that they cannot get into narrow spaces or between two obstacles too close to each other, such as the legs of two pieces of furniture positioned side by side.
  • this operation does not allow the cleaning of those narrow spaces that are beyond the lateral overall dimensions of the nozzle unit, i.e. the distance between the side edge of the nozzle unit and the suction pipe.
  • the known nozzle units force the user to make various manoeuvres with the pipe with handle of the vacuum cleaner and the nozzle unit to reach the entire area around the leg.
  • nozzle unit in which the front part is formed by two elements hinged to the median-front part of the nozzle unit that can be rotated by about 45 degrees each towards the nozzle unit rear.
  • This nozzle unit allows cleaning the room corners but it does not allow easy cleaning around the obstacles in the room, such as table legs and does not allow the nozzle unit to get into narrow spaces.
  • Patent US3608126 describes a nozzle unit with two side wings that can be rotated backwards to get into narrower spaces. Such nozzle unit, however, requires several manoeuvres to clean around the fixed obstacles in the room.
  • Td ⁇ overcome all these ⁇ disadvantages, aHew nozzle unit for vacuum cleaners has been designed and constructed.
  • One purpose of the new nozzle unit is to allow accurate cleaning also along the baseboard and in the corners.
  • Another purpose of the new nozzle unit is to have the possibility to get it into narrower spaces without forcing the user to particular manoeuvres.
  • Another purpose of the new nozzle unit is to clean around the obstacles on the floor without requiring the user to make particular manoeuvres.
  • the new nozzle unit consisting of a main rotating body on which three radial spokes are hinged.
  • the main body has a generically triangular shape, either equilateral or isosceles, and it is provided with a coupling on its upper part for the suction pipe with handle of the vacuum cleaner.
  • Such coupling in addition to mechanically connect and put in communication the internal part of the main body with the suction pipe, also allows the complete horizontal rotation of the main body with reference to the coupling and tilting the suction pipe with reference to the entire new nozzle unit.
  • the main body of the new nozzle unit has openings and ducts that connect each spoke with the coupling and therefore with the suction pipe of the vacuum cleaner too.
  • Each spoke has a substantially linear shape with an opening on the upper part, one closed end and one open end.
  • each spoke is hinged on said main body at the vertexes of its triangular ⁇ shape ⁇ so ⁇ as “ to " rotate namely " around the main body while remaining always in contact with the floor.
  • each spoke has a linear rectangular shape oriented along the length of the spoke and it can be provided with one or more brushes or other devices to collect the dirt.
  • each spoke has one or more elastic elements to keep the spoke in its normal position.
  • one single elastic element connected to the spokes and the main body keeps said spokes in their normal positions.
  • the spokes When in their normal positions, the spokes are oriented along the bisecting line of the corners of the triangular shape of the main body of the new nozzle unit.
  • the main body has the shape of an equilateral triangle, that the spokes are arranged at 120 degrees between each other and that the coupling is in the middle of the main body at the crossing of the three directions of the three spokes.
  • the rotation of the spokes on the mam body and the rotation of the main body around the coupling enable the new nozzle unit to adjust to the various operational situations and to the various possible obstacles without requiring the user to make manoeuvres with the pipe with handle.
  • the new nozzle unit adheres to a continuous linear obstacle like a wall
  • the front spokes pull apart by rotating towards the rear spoke until they get substantially aligned to each other and with the edge of the main body between them. In this position, the two spokes and the main body can clean -the -floor up to the walhora continuousDbstacle.
  • the new nozzle unit When the new nozzle unit has to get into a narrow space, it is moved forward with a spoke looking forward and the other two looking generically sideways and backwards. The front spoke gets into the narrow space while both generically lateral spokes bend backwards thus reducing the advancing front to the minimum.
  • the minimum necessary width for the new nozzle unit is the distance between the ends hinged to the main body of two spokes.
  • the turned spoke is called back to its normal position by said elastic elements.
  • An element or mechanism is foreseen to lock the mutual rotation between the main body and the coupling that can be operated by the user, for example directly from the handle or by means of a lever located on the main body of the nozzle unit so as to prevent or allow the free rotation of the nozzle unit and bind it into a specific position chosen by the user.
  • Two main positions are preferred: one position in which the new nozzle unit has a spoke looking towards the directions in which the new nozzle unit moves and one position in which the two spokes look generically sideways and forwanhand ⁇ theT third " spoke ⁇ is " o ⁇ ente " d in the opposite direction of tHe one in which the new nozzle unit moves.
  • a baffle element is foreseen that is hosted inside the main body and is connected through the coupling or is fastened to it or is part of it so as to shut the connection between said main body and the spoke that looks backwards. In this way, the suction power is concentrated on the two spokes looking sideways and partially forward while leaving unused or inefficient the spoke being dragged that is less useful in this position.
