Definitions

  • the present invention relates to a rotatable connection between a vacuum cleaner hose and a handle part, wherein the hose is connectable to a vacuum source arranged in a vacuum cleaner housing.
  • connections of the foregoing type are known in the art. Such connections are usually designed such that the handle part can be turned an indefinite number of revolutions in each direction.
  • connection In order to prevent the conductors from being turned too much the connection is designed such that the handle part can only be turned or rotated a limited angular amount in each direction from an intermediate position, with the complete turning motion being less than 360°.
  • the last-mentioned turning motion is limited by means of shoulders arranged on the handle part and on the hose.
  • Vacuum cleaners having a dust container arranged in a handle part are also previously known, as shown in GB 1443494.
  • the handle part is, via a hose, connected to a vacuum cleaner housing which encloses a fan unit.
  • control and operating means may include switches for the fan unit and a motor-driven brush nozzle which is arranged on the handle part.
  • a rotatable connection between the hose and the handle part in order to achieve sufficient flexibility and maneuverability. Such a rotatable connection would allow the electrical energy to be transmitted in a simple way from the vacuum cleaner housing to the handle part.
  • the present invention is directed toward a rotatable connection which eliminates or minimizes the above-mentioned disadvantages in the prior art.
  • the present invention is further directed toward a simple, cheap and, hence, a preferable alternative to a conventional slip ring coupling for supplying electrical energy to the handle part or to a motor-driven nozzle connected to the handle part.
  • a connection for rotatably securing a vacuum cleaner hose to a handle part permits a range of rotation between the hose and handle part which is greater than 360°.
  • the connection is provided by a first threaded part and a second threaded part which cooperate with one another.
  • the handle part supports one of the threaded parts and the hose supports the other of the threaded parts.
  • a vacuum cleaner includes a vacuum cleaner housing 10 enclosing a motor fan unit 11 whose inlet side is connected to one end of a hose 12 by means of a removable coupling 13.
  • the other end of the hose 12 is rotatably secured to a handle part 14 by means of a connection 15.
  • the handle part 14 is removably secured to a tube shaft 16 which, in a conventional way, is connected to a nozzle 17.
  • the handle part 14 is provided with a handle 18 supporting control means 19 such as switches for connecting and disconnecting the fan unit and a motor-driven brush nozzle (if any).
  • the handle 18 also supports a dust container 20 in which dust, which is taken up by the nozzle 17, is separated before the cleaned air continues through the hose 12 to the motor fan unit 11.
  • the hose 12 receives a free cable 21 having conductors which transmit current from the vacuum cleaner housing 10 to the handle part 14.
  • the conductors of the cable 21 are, at one end, secured to the electric components which are positioned in the handle part 14 and, at the other end, are connected to a plug 22 arranged on the hose 12.
  • the plug 22 is electrically connected to a socket 23 on the vacuum cleaner housing.
  • connection 15 comprises a screw-nut arrangement designed as an outer sleeve 24 and an inner sleeve 25.
  • the outer sleeve 24 is fixed to the handle part 14 and has an inner thread 26.
  • the inner sleeve 25 is fixed to the hose 12 and has an outer thread 27.
  • the outer thread 27 has a smaller number of thread turns than does the inner thread 26, which means that the inner sleeve 25 can be turned with respect to the outer sleeve 24. However, the turning motion is limited by the axial length of the inner thread 26.
  • the outer thread 27 of the inner sleeve 25 has two turns while the inner thread 26 of the outer sleeve 24 has six turns. Accordingly, from an initial starting or intermediate position, the handle part 14 can be rotated two turns in each direction to a suitable end position. One of the end positions is shown in FIG. 2. Preferably, rotation is limited to less than three turns in each direction from the center or intermediate position.
  • the illustrated arrangement allows a turning motion between the handle part 14 and the hose 12 which is greater than 360° but limits range of movement with simple means to thereby preventing damage to the cable.
