Definitions

  • the present invention relates to devices for and arrangement of vacuum cleaner enabling the user:
  • a to start and stop the machine connect hoses, change nozzle, adjust the length of the tube and operate other functions, while standing in an upright position,
  • the invention can also be used as a wet suction cleaner or a combined wet and vacuum cleaner.
  • the arrangement can also be combined with other cleaning equipment.
  • Vacuum cleaners used in homes and for premises of moderate size are of various types, but common to them all is that they are operated close to floor level. The user must therefore bend down to start, stop and control the equipment, connect tubes, hoses, suction nozzles, etc. Even while actually cleaning the user is forced to stand and walk leaning forward.
  • Admittedly chargeable vacuum cleaners with long tubes exist which allow vacuuming to be performed in an upright position or leaning slightly forward.
  • Large vacuum cleaners intended for use in industry, hospitals and so on also exist, that are equipped with some of the functions utilized in the present invention. However, none of these fulfils the important demands featured in the present invention.
  • the present invention is characterised in that a vacuum cleaner is applied on a dirigible trolley.
  • the vacuum may be connected to the mains or battery driven.
  • the vacuum cleaner and trolley may also be manufactured as a single unit Certain standard vacuum cleaners, primarily those intended for professional use, have a wide wheel base and good manoeuvrability. This type of vacuum cleaner can be provided with supplementary devices in order to fulfil the requirements according to the present invention.
  • Figure 1 illustrates a vacuum cleaner 1 applied on a trolley 2, and other essential devices characterising the invention.
  • the trolley and vacuum cleaner may be built as a single unit but the devices otherwise will be substantially the same.
  • vacuum cleaner is positioned vertically, which is best if it is long and narrow in shape. Vacuum cleaners with a more compact shape are suitably positioned horizontally.
  • the arrangement shall be provided with a frame 3 and a steering bar 4.
  • the frame a steering bar are preferably manufactured in one piece, e.g. from a bent metal tube as shown in Figure la.
  • the frame may also be used for attaching vacuum cleaner, controls, etc.
  • the arrangement may also be equipped with handles 5 which may also be exchangeable and adapted for various types of handicap or other individual requirements.
  • the steering bar 4 is located at a level enabling the user to operate the equipment in an upright position. It is practical for the frame to be made vertically adjustable, 6, for individual adjustment.
  • the tube 7 of the vacuum cleaner is provided with an attachment 8 which should be jointed so that the tube can be moved to vertical position 9 where it can be clamped by means of a bayonet coupling 9 A.
  • the tube attachment 8 is suitably secured to the frame but may alternatively be applied on the trolley, 8 A.
  • the attachment 8 must thus be jointed in vertical direction. It must be stable laterally so that the tube follows the movement of the trolley without becoming displaced laterally.
  • the attachment may also be provided with an extra joint to permit lateral movement, thereby giving greater accessibility in cramped spaces. Such an extra lateral joint must be operable and lockable from an upright position.
  • the vertical joint and lateral joint if any may be of traditional type, such as hinges, sliding, ball, roller or disc bearings as 8 in Figure 2.
  • the tube 7 should be of telescopic construction 10 so that its length can be adjusted. It may consist of two or more parts.
  • the tube shall also be equipped with a bayonet coupling 11 located at such a distance from the attachment 8, 8 A, that it will be approximately on a level with or just below the steering bar when the tube is moved to vertical position. In said vertical position the user can, while standing upright, adjust the length of the tube by means of the telescopic function. In this position also the bayonet coupling can be used to change to a different accessory.
  • the bayonet coupling can be used to change to a different accessory.
  • vacuuming furniture e.g. beds
  • the trolley can be used as a support, placing one hand on it and vacuuming with the other. The possibility of vacuuming manually may be practical for other places difficult to access, even on floor level.
  • the tube is used extended to its full length primarily when vacuuming under beds. If the distance from the front of the trolley to the suction nozzle is set at about 2 m it is possible to vacuum under double beds from the short end, assuming that there is sufficient space in the room otherwise.
  • devices are described which enable the length of the tube to be adjusted while vacuuming is in progress, without raising the tube to vertical position.
  • Raising and lowering the tube is achieved using controls placed on or in the vicinity of the steering bar, or possibly using a foot pedal so that the user can performed the operation in an upright position.
  • the grip of the operating controls can be designed to suitable various types of handicap or other individual requirements.
  • the tube can be raised or lowered manually or by a purely mechani:al device, with the aid of an electric motor or pneumatically by utilizing the suction and/or exhaust of the vacuum cleaner. In the latter case commercially available pneumatic cylinders with plungers driven by over pressure and/or under pressure are used.
  • Figure 2 illustrates a mechanical device for operating the tube.
  • the operation is performed with the aid of a wheel 12 provided with adjustable slip brakes and a drum on which a "Venetian blind cord” 13 is wound, the other end of the cord being attached to the tube at 14.
  • This arrangement has also proved valuable when vacuuming soft rugs lying on hard, polished floors. It has been found that releasing the suction of the nozzle slightly with the aid of the wheel 12 prevents the rugs from slipping and rolling up. The weight of the nozzle and tube, i.e. pressure against the floor combined with the suction effect otherwise cause loose rugs and the like to be displaced.
  • the device according to Figure 2 may be supplemented by an electric motor if the user, due to some handicap or the like, is unable to operate it by hand.
  • the tube shall be applied so that when in lowered position it is at a slight angle to the floor as shown in Figure 1. It is thus possible to stand upright while vacuuming under beds and other places which are normally difficult to reach with a vacuum cleaner.
  • the standard nozzle may be replaced by a special nozzle 16 having a height of about 30 mm, combined with a bent tube 17. Since the tube 17 is bent its outermost part will be parallel to the floor, thereby enabling vacuuming underneath low pieces of furniture. The suction gap of the specially designed long, narrow nozzle 16 should be narrowest nearest to the tube, becoming wider towards the other end. Suction is thus achieved along the entire length of the special nozzle.
  • the bent tube 17 may of course also be used together with the standard nozzle.
  • the rectangularly shaped standard nozzle provided as part of the equipment for all commercially available vacuum cleaners of normal size is generally used for vacuuming floor surfaces.
  • This nozzle is so designed that its angle to the tube can be altered by turning the shaft. This provides access to corners. According to the present invention this turning of the tube can be achieved with the aid of wires operated from the steering rod, which lead to a device transmitting the movement to the tube.
  • the present invention is characterised in that the vacuum cleaner is mounted on or combined with a trolley. Vacuuming is thus steered by steering the whole trolley. Devices can also be added which allow the tube to perform various types of movements. In the simplest case a to and fro movement is achieved in the longitudinal direction of the tube, e.g. by exploiting the telescopic function of the tube. With such a device the user need only steer the trolley laterally in order to vacuum a certain area. Such a device is also valuable in the cramped areas often occurring in a home. Space is often limited, for instance, when vacuuming in a bedroom with double beds. Using a telescopic tube, the length of which can be adjusted from the steering handle enables restricted areas to be vacuumed.
  • Figure 5 shows a device in which 7 denotes a telescopic tube the length of which is adjusted by means of a helical spring 19 surrounding the tube nearest the suction nozzle 20.
  • the helical spring is attached to the tube with a flange 21. The end of the spring rests against a second flange 22 which is secured to the outer tube.
  • a wire 23, or preferably one on each side of the tube, is attached to an eye 24 anchored in the flange 21.
  • the wire leads to the steering bar where it can be operated and produces the movement 25 along the outermost part of the telescopic tube.
  • the wire can be operated manually or it can be operated with the aid of an electric motor, or pneumatically, possible in cooperation with the same source as described earlier for effecting raising and lowering of the tube.
  • Vacuuming is often performed in poorly lit areas. We have found it advisable to provide the equipment with illumination to illuminate the area being cleaned. This may advantageously be placed at the front of the trolley, on the actual nozzle or on the suction tube.
  • the nozzle of the vacuum cleaner may be replaced by a washing device such as a floor mop or sponge, in which case the other functions according to the invention can also be utilized.
