Definitions

  • This invention relates to a vacuum cleaner nozzle comprising the combined features of the preamble portion of claim 1.
  • Vacuum cleaner nozzles for multi purpose use of the type mentioned above are previously known, see for instance DE 2846847 .
  • Such nozzles are provided with a retractable plate that is provided with a brush strip surrounding the suction opening.
  • the retractable plate is released manually by the operator such that the nozzle is partly supported by the brush whereas the retractable plate is moved by the operator to its upper position out of engagement with the floor when cleaning soft materials such as pile carpets.
  • the suction plate is in engagement with the surface and air is drawn through the material into the suction opening. Since the suction plate is pivotally supported in the nozzle body the suction plate will follow the irregularities in the floor and decrease the forces that are necessary to move the nozzle on the floor.
  • a disadvantage with this type of nozzle is that manual efforts are necessary to shift between bare floor and soft floor cleaning.
  • JP-A-2003-339586 discloses a nozzle where manual shifting is not necessary.
  • the main object of our invention is to achieve a nozzle that can be used on hard surfaces as well as on soft carpets without any cumbersome procedures from the operators side and also to eliminate the shifting mechanism.
  • Fig. 1 is an exploded view of the nozzle
  • Fig. 2 is an enlarged perspective view from above of a suction plate that is an inner part of the nozzle
  • Fig. 3 is an enlarged perspective view of said suction plate from below
  • Fig. 4 is an enlarged perspective view of a strip shaped element supported by the suction plate
  • Fig. 5 is an enlarged perspective view of a nozzle body that supports the suction plate
  • Fig. 6 is a vertical section at the central part of the nozzle.
  • the suction plate 10 is also provided with a strip shaped element 16 made of elastic material such as rubber, plastic or bristles.
  • the strip shaped element is removably secured on an elongated strip support 17 arranged parallel to and behind the suction opening.
  • the strip support 17 is secured to two yokes 18 that are made of flexible material and that extend in the forward direction. Each yoke 18 is at its forward end secured to the front end of the suction plate whereas the strip support 17 rests against the suction plate in order to define a lowest position for the strip shaped element 16.
  • the suction plate 10 has two communicating channels each extending from the air passage between the suction opening 13 and the outlet 14 to a tube shaped shaft 19 on which one end of a flexible bellow 20 is arranged and whose other end is secured to the strip support 17.
  • the nozzle body 11 constitutes at its rear end a bottom plate 21 that continues in the forward direction as an elongated box shaped structure 22 that is open at the bottom side.
  • a support wheel 24 At the front part on each opposite side wall 23 of the box shaped structure there is a support wheel 24 whereas there also are two supporting wheels 25 at the rear part of the nozzle body each arranged in a wheel housing 26.
  • At the central part of the box shaped structure 22 there is an opening 27 through which the upper portion of the suction plate partly extends at the same time as the pivot shafts 15 are arranged in separate pockets 28 in the nozzle body and are secured by means of locking springs 29 such that the suction plate 10 can tilt about the pivot shafts 15 and with respect to the nozzle body 11.
  • the nozzle body is also provided with a cover 30 that can be fixed to the body in order to hide the parts underneath.
  • the nozzle operates in the following manner.
  • the wheels 24, 25 support the nozzle such that the bottom plate 21 of the nozzle body 11 as well as the lower portion of the suction plate 10 with the suction opening 13 are placed somewhat above the floor. This means that a slot is created between the suction opening and the floor through which air is drawn with high velocity. Due to the high pressure (low vacuum) in the outlet 14 the spring forces from the yokes 18 override the suction forces in the bellows 20 which means that the strip shaped element 16 is in its lower position abutting the floor. This means that air is prevented from entering the suction opening from the rear side of the nozzle and the suction force is instead concentrated to the front part and the side parts of the nozzle.
  • the suction plate 10 When the nozzle is moved in the forward direction the suction plate 10 is, because of the friction engagement with the floor material, tilted somewhat backwards about the pivot shafts 15 such that the smooth area in front of the suction opening slides on the material. This even further reduces the horizontal forces that are needed from the operator's side to move the nozzle. When the nozzle is moved in the backward direction the suction plate will tilt towards the front part of the nozzle and the smooth area at the rear outer side of the suction opening will engage the floor with the same consequences as mentioned above.
