Abstract
Description
- This invention relates to vacuum cleaner apparatus of the kind including a suction inlet and a hose connected with the inlet.
- Vacuum cleaners may be of the upright kind where cleaning suction is applied by means of a pump having an inlet directly below the machine. Cylinder vacuum cleaners, by contrast, have an inlet to which one end of a hose is connected, the other end being connected to a suction head. Upright cleaners also usually have provision by which a hose can be connected to the inlet so that a hand-held suction head can be used to clean regions that would otherwise be inaccessible to the machine. The hoses used with vacuum cleaners tend to be bulky so that they have to be stored separately from the cleaner. An alternative hose available on some vacuum cleaners as sold by the major manufacturers has stretch characteristics with a natural, retracted length (when not in use) that is less than its extended length (when in use). The extended length may be about five times the retracted length, as shown for example in GB-A-2 310 369. Although this hose has the advantage of being much easier to store than conventional hoses, its resilience may make it more difficult to use in some situations, especially with cylinder vacuum cleaners, which are lighter than upright cleaners.
- US-A-2 867 833 shows a suction cleaner with a hose according to the preamble of the independent claim.
- It is an object of the present invention to provide an alternative hose and vacuum cleaner apparatus including such a hose.
- According to one aspect of the present invention there is provided vacuum cleaner apparatus of the above-specified kind, wherein the hose has a first length during normal use and a second length shorter than the first length when the end of the hose remote from the inlet is occluded so that pressure falls within the hose. The hose has a helical support member and a sleeve attached thereto, the sleeve being arranged to fold outwardly between turns of the support member when the hose is retracted in length.
- A part at least of the length of the hose may have a natural extended length. A part at least of the hose may have a natural retracted length. The hose may include a valve towards the end remote from the inlet for occluding the hose. The apparatus preferably includes a restrainer for restraining the hose in its shorter length. The restrainer may be fixed with a housing of the apparatus and may include a sleeve within which the hose is retracted. The apparatus may be portable.
- The hose may have a natural extended length and be retractable in length by the application of reduced pressure within the hose. The hose preferably has an occluder towards the end of the hose remote from the vacuum cleaner apparatus for occluding passage of air through the hose so that suction applied by the vacuum cleaner apparatus creates a reduced pressure within the hose sufficient to shorten the hose to its retracted length. The hose may include a retainer arranged to retain the hose in its retracted length such that the hose and retainer can be removed from the vacuum cleaner and stored separately in a retracted state. The hose includes an inner resilient helical support member having a natural extended length and an outer sleeve of a flexible material attached with the support member.
- According to a further aspect of the present invention there is provided a method of operating vacuum cleaner apparatus as defined in the independent claim 9.
- The method may include the step of removing the hose from the vacuum cleaner apparatus in its retracted state.
- Vacuum cleaner apparatus including a hose according to the present invention, will now be described, by way of example, with reference to the accompanying drawings.

- Figure 10
- is an enlarged simplified elevation view of a part of an alternative hose;
- With reference first to Figures 1 to 4, the vacuum cleaner is of the portable cylinder type having a
housing 1 withwheels 2 on its lower surface and asuction inlet 3 at one end. The cleaner includes a conventional pump and dust collection bag or other container (not shown). On one side of thehousing 1 there is a hose restraint and mount in the form of abracket 4 with aU-shape flange 5, the purpose of which will become apparent later. - The cleaner also includes a
hose 10. Thehose 10 is of a flexible, corrugated construction including a resilient, helical reinforcement member in the form of a spring metal wire 11 internally supporting an outer highlyflexible plastics sleeve 12. The reinforcement helix could be of a resilient plastics material. The reinforcement wire 11 is formed so that it has a naturally extended state but can be compressed axially against its resilience by an applied external force. Thesleeve 12 is sufficiently flexible that the hose itself naturally takes up the extended length of the reinforcement wire helix 11, as shown in broken outline in Figures 1 and 2. As shown in Figure 4 not within the scope of the invention, thesleeve 12 of the hose, in its extended state, has inwardly-extending shallow valleys between each turn of the reinforcement. This allows the sleeve to fold up internally between the turns of the turns of the reinforcement so that the hose can retract freely when a compressive force is applied. According to the invention, as shown in Figure 10, the sleeve 12' may have shallow hills extending outwardly between turns of the reinforcement element 11'. This allows the sleeve 12' to fold outwardly when the hose is retracted. This arrangement may have advantages in that the bore of the hose is not reduced during retraction so that the suction pressure along the length of the hose is maintained. - The stiffness of the hose construction can be tailored to give the desired rate of retraction.
- At one end, the
hose 10 has aconventional coupling 13 by which the hose is connected to thesuction inlet 3 of the cleaner, this may include a swivel connection. At its opposite end, thehose 10 has asecond coupling 14 by which the hose is attached to acleaner head 15. - The
coupling 14 includes within it means by which air flow through thehose 10 can be occluded. As shown in Figure 4, this takes the form of aflap 16 pivotally mounted at oneend 17 within thecoupling 14 and urged to an open, longitudinally-extending position by aspring 18. One end of abutton 19 is exposed externally of thecoupling 14, its other end being positioned above the flap within the coupling. By pushing down on thebutton 19, the free end of theflap 16 is also pushed down against the resilience of thespring 18. Once depressed a certain distance, air flow along thehose 10 causes theflap 16 to be pulled down to a vertical position where it abuts anannular seat 20 within the coupling and occludes the passage along the hose. Theflap 16 remains in this closed position until suction is removed, when thespring 18 swings it back to its original position. The rear end of thecoupling 14 locates on one side of the mountingflange 5 to retain the free end of thehose 10 in position against the side of thecleaner housing 1, when not in use. Thecleaner head 15 may be stored in a compartment within thehousing 1. - To use the cleaner, the
coupling 14 at the free end of thehose 10 is pulled out of the restrainingbracket 4. This allows thehose 10 to adopt its natural extended state, which may typically be about 2m in length. Thecleaner head 15 is then fitted on thecoupling 14 and power to the cleaner is turned on so that it applies suction to thehose 10 and cleaner head. This is used in the conventional way, to suck dust and the like into the cleaner for subsequent disposal. - When the user has finished with the cleaner, before turning off power supply, he presses the
button 19 at the free end of thehose 10, so as to close thevalve 16 and prevent air flow into the hose. The pressure in thehose 10 between thevalve 16 and the cleaner now drops rapidly. This applies an axial, compressive force to thehose 10, which is sufficient to retract it against the resilience of the reinforcement wire 11. The construction of thehose 10 is such that it retracts to a length substantially less than its natural length, typically about half its natural length, that is, about 1m long. The construction of the hose is selected such that the reduced pressure within the hose during normal cleaning operations is not sufficient to cause any appreciable retraction of the hose length. The user removes thecleaner head 15 and fits thecoupling 14 into therestraint 4. Once thecoupling 14 is fitted in therestraint 4, the power to the cleaner can be turned off. As soon as power is turned off, pressure will start to rise in thehose 10 because the vacuum cleaner is not air-tight, allowing air to enter and re-pressurize the hose. The retractive, compressive force on the hose will, therefore, fall and the hose will tend to resume its natural, extended length. However, because the free end of thehose 10 is restrained by therestraint 4, the hose will not be able to extend until released from the restraint. The hose restraint may include a shaped housing within which a major part of the length of the retracted hose is located. Thehose 10 could be retained within a curved channel in the housing beneath a hinged lid of the housing so that it is completely enclosed. - The present invention enables a vacuum cleaner hose to be stored compactly without the need for the user to apply a force to extend the hose. This, therefore, enables the hose to be used with lightweight cleaners, which might be pulled over or pulled along by pulling on a conventional stretch hose.
- The hose need not have a natural extended length. The invention could also be useful where the hose has a natural retracted length. The resilience of the hose tending to retract it can be made weaker than in a conventional stretch hose because the reduced pressure created when the free end of the hose is occluded would help retract it. In this way, the problems associated with conventional stretch hoses on portable vacuum cleaners can be reduced or avoided because less force has to be applied to extend it. The hose could have a combination of the naturally-retracted and naturally-extended kinds and or alternatively, could have a section that is neither retractable or extensible.
- It will be appreciated that the present invention is not confined to cylinder cleaners but could be used with, for example, upright cleaners.
- The hose described above is constructed so that an increase in suction pressure causes a corresponding directly related reduction in hose length between the fully extended and fully retracted states. Alternatively, the hose could be constructed so that there is no significant reduction in length up to a certain suction pressure and, once a threshold is exceeded, the hose snaps to its fully retracted length. Such a hose can be provided by making the configuration of the corrugations asymmetrical.
- The valve for preventing air flow along the hose can have many different constructions. The valve could be provided by some form of plug, such as shown in Figure 5 where a
ball 20 is attached with thecoupling 21 by a flexibleelastic tether 22, so that the user simply holds the ball up to the end of the coupling to block flow. The valve need not totally block air flow but may be constructed to allow a reduced flow of air. This may be useful so as to reduce the speed at which the hose retracts. The valve could be adjustable to allow different rates of air flow. Instead of using a valve, the hose could be blocked simply by the user pressing his hand over the end of the coupling. The valve could be arranged so that it is automatically closed when the cleaner head is removed. The valve could have an electric operation so that it can be operated remotely, such as by a switch on the cleaner housing. This might be arranged such that the OFF button on the cleaner automatically closes the valve before suction is turned off. - The hose need not be retained in its retracted state by the housing of the vacuum cleaner. Instead, some form of retaining means separate from the vacuum cleaner body could be provided, such as, for example shown in Figures 6 to 9.
- Figure 6 shows a
retractable hose 30 of the kind described above having acoupling 31 1 at one end connected with a vacuumcleaner housing 32 and acoupling 33 at its opposite end for connection to a cleaning tool (not shown). Attached with bothcouplings cylindrical sleeve sleeve respective couplings free end sleeve means sleeves sleeves hose 30 at thecouplings sleeves hose 30 is blocked so that it retracts, the twofree ends sleeves sleeves hose 30 in its retracted length. The retractedhose 30 can be stored on the vacuum cleaner body or it can be uncoupled at thecoupling 31 and stored separately, such as by means of a hangingloop 40. - Instead of smooth sleeves, as shown in Figure 6, the sleeves 34' and 35' could be corrugated as shown in Figure 7, with a natural retracted length so that they cover less of the hose 30' when the cleaner is in use. To fasten the sleeves 34' and 35' together, the user simply pulls their free ends 36' and 37' together to stretch out the sleeves to their full length so that the engaging means 38' and 39' can be fastened together.
- It is not essential to have two sleeves at opposite ends since a single
longer sleeve 42 could serve the same function, as shown in Figure 8. - The sleeve or sleeves need not be solid but could, for example, instead be provided by webbing material or by a series of straps disposed around the hose.
- There are many alternative forms of retainer means that could be used to hold the hose in its retracted length. The retainer means could be in the form of a bag that is closed about the retracted hose. Such a bag could also have provision for storing the cleaning wands and accessories after detachment from the hose.
- The retainer need not be permanently attached to the hose itself but could be a separate component that is only attached with the hose when the hose is retracted.
- Figure 9 shows a separate retainer in the form of a rigid casing having two
shells flexible hinge 52 and havingsemicylindrical recesses 53 on one surface.Semicircular ribs shells flanges 57 at opposite ends shaped withrecesses 58 into which the rigid cleaning wands or other accessories can be clipped, so that the hose and accessories can be stored together. - The retainer could extend internally within the hose and could, for example, be provided by a rigid vacuum cleaner wand and suitable couplings.
