Definitions

  • My invention relates to Vacuum cleaners and more particularly to the combination with a vacuum cleaner unit of a flexible hose for connecting the suction or blowing tools with the vacuum cleaner unit.
  • Fig. 1 is an assembly View showing the vacuum cleaner unit with the hose attached thereto;
  • Fig. 2 shows a detail
  • 10 denotes a suction clean er unit of known kind comprising a casing enclosing a dust bag 20 and a fan 21 driven by an electrically operated motor 22. of the cleaner casing are covered by caps 11 and 12, respectively, in which caps the suction and blowing openings 13 and 14 respectively are arranged. Said openings 13 and 14 are adapted to receive a coupling member 17, as shown more in detail in Fig. 2. 'The coupling member 17 is threaded at 24 to fit into the inlet opening 13. The coupling member isinternally threa ed at 25 to permit a ro- The ends,
  • Member 26 is a part of the'hose generally des ignated by reference character 15; 26 is rotatably mounted on a rigid sleeve or in the drawing, the hose may be of so-called spiral construction.
  • the cleaner unit rests on the floor or carpet.v
  • the operator lifts the part 31 and holds either this or some adjacent part in the hand. Consequently, the part of the flexible hose which-is nearer to the cleaner unit 10 rests on the floor, whereas the part sectional area, while the part ad acent the member 31 is appreciably lighter. If the hose were of uniform diameter equal to the diameter adjacent the part 31,.the resistance would be high compared with the hose as shown and described.
  • the invention further provides the advantage that, in the suction operation, thread, cotton-waste and the like will not stick in the hose as this increases in the direction of fiow of air. This last mentioned advantage is particularly important in spiral hoses.
  • the vacuum cleaner unit is adapted to be pulled on the floor or carpet by pulling on the hose.
  • the part 19 may be omitted and the suction tool connected directly to the member 31, or the member 31 may itself constitute the nozzle, as is known in cleaners of this type. It is to be understood that the invention is not limited to the specific type of. vacuum cleaner shown and described.
  • a vacuum cleaner unit includin a casing having a suction inlet adjacent the oor, of a hose adapted to be held inthe hand at one end and secured to said inlet at the othervend and of such length as to have a'portion thereof resting on the floor when anend'is held in the hand
  • a flexible section of varying internal and external diameter to provide varying cross-sectlonal area and varying weight per unit length,ithe smallest cross-sectional area being at the end to be held in the hand and the largest cross-sectional area being at the end adapted to be attached to said suction inlet whereby the end to be held in the hand is relatively light andthe part resting on the U .area being at the end to be heavy and the cross-secfloor is relatively the direction of air tional area increases in flow with the hose connected to the suction inlet,
  • a movably mounted vacuum cleaner unit including a casing having a suction inlet adjacent the floor, of a hose adapted toibe held in the hand 'at one end, said hose serving to conduct ai to the vacuum cleaner unit and for pulling the unit on a floor or other surface, a rotary connection between said hose and said inl t at the other end and said hose being of such length as to have a portion thereof resting on the floor when an end is held'in the hand and comprising a flexible section of varying internal and external diameter to provide a varying cross-sectional area and varying welg t per unit length, the smallestcross-s'ectional held in the hand mounted vacuum cleaner unit including a castion.
  • a vacuum cleaner unit having an inlet open-j ing, a suction nozzle, and a hose comprising a rigid end member adapted to be connected to said nozzle and comprising a flexible hose section attached to said endmember and having a gradually increasing internal diameter away from said rigid end member and a similarly increasing external diameter and comprising a connection memberattached to the large diameter end of the hose vsection and adapted to be connected to said inlet opening.
  • a vacuum cleaner 1 unit including a casing having a suction inlet, and a suction nozzle, of a hose adapted to be held in the hand and connected to the suction nozzle at one end and connected to said sueto conduct air to the vacuum cleaner unit and being of'such length as to have a portion thereof resting on the floor when an end is held in the hand,said hose comprising portions and a flexible section of varying m- 125 ternal and external diameter connected between said rigid portions to provide varying cross-sectional area-and varying weight per unit length, the smallest cross-sectional area being at the end to be held the hand and the 13.
  • said hose serving largest cross-sectional area being at the end nearer the suction inlet, whereby the end to be held in the hand is relatively light and the part resting on the floor is relatively heavy and the cross-sectional area increases in the direction of air flow with the hose connected to the suction inlet and the center of gravity is nearer the'unit, relative to a hose of 11111- form diameter.
