Handle Assembly for a Cleaning Appliance
The invention relates to a handle assembly for a cleaning appliance, particularly but not
exclusively to a handle assembly for a vacuum cleaner of the upright type.
The general construction and method of operation of upright vacuum cleaners are both
well known. Also well known is the capability of upright vacuum cleaners to be
converted from a traditional upright cleaning mode (in which the entire vacuum cleaner
is manoeuvred across a floor surface) into a cylinder mode for "above-the-floor"
cleaning. For such purposes, upright cleaners often incorporate an integral hose and
wand arrangement which can be brought into operation when required. In some cases,
the hose and wand assembly consists of an integral hose which forms part of the airflow
path between the cleaner head and the separation apparatus when the machine is used in
upright mode, with one end of the hose being releasable from a socket in the main body
when above-the-floor cleaning is to be carried out. A separate wand, which is often
carried on the main body of the vacuum cleaner, can then be attached to the hose for
improving the reach of the hose and wand assembly. A disadvantage of this type of
arrangement is that, when the machine is used in upright mode, the incoming air still
has to travel through the hose which unnecessarily increases losses.
Another known type of hose and wand assembly is that used on the Dyson range of
upright vacuum cleaners, model numbers DC01, DC03, DC04 and DC07. In these
vacuum cleaners, the lower end of the hose is fixedly connected to the main body of the
respective cleaner but the upper end is slidingly connected to the tubular portion of a
wand handle. The wand handle comprises a moulded handle portion with a tubular
wand rigidly connected thereto. The handle portion can be attached to the main body of
the vacuum cleaner and used in the manner of a handle, in which case the upper end of
the hose is slid to the upper end of the wand so that the wand is then stored inside the
hose. When above-the-floor cleaning is required, the handle portion is released from
the main body, the upper end of the hose is slid to the lower end of the wand and tools

can be attached to the handle portion to effect the cleaning required. A valve
arrangement automatically selects the point of entry of the dirty air into the vacuum
cleaner: in upright mode the point of entry is via the cleaner head and for "above-the-
floor" cleaning the point of entry is via the hose and wand. The principle by which this
entire arrangement operates is described in EP 0037674B.
A disadvantage of this arrangement is that, because the handle portion is designed to be
used as the handle of the machine in the upright mode, the arrangement of the handle is
not ideally suited for "above-the-floor" mode. The user tends to grip the lower end of
the wand remote from the handle portion when carrying out "above-the-floor" cleaning,
at least when cleaning areas at high levels such as cornices and curtain rails. In a
refinement of the arrangement, some Dyson vacuum cleaners have incorporated a hose
and wand assembly in which the handle portion and wand can be released from the
upper end of the hose, turned around and reconnected in the reverse orientation. In this
way, when the hose and wand assembly is to be used for "above-the-floor" cleaning, the
hose is attached to the handle portion with the wand then projecting away from the hose.
This provides better grip for the user and belter balance of the handle and wand during
use. This arrangement is shown and described in detail in WO 01/65989. A
disadvantage of even this refined arrangement is that the user is required to disassemble
and reassemble the hose and wand assembly prior to use for "above-the-floor" cleaning
and then, of course, to reverse the operation before returning to normal upright mode.
This can result in incorrect assembly which could lead to a reduction in performance
due to air being bled into the assembly through inefficient seals.
The present invention seeks to provide an improved handle assembly for a vacuum
cleaner which obviates the disadvantages of the prior art.
The invention provides a handle assembly for a cleaning appliance comprising a flexible
hose having a first end connectable to a main body of the cleaning appliance and a
second end, a handle portion for manoueuvring the cleaning appliance across a surface
to be cleaned, and a tubular wand, characterised in that the second end of the flexible

hose is connected to the handle portion and the tubular wand is slidably mounted in the
handle portion so as to be slidable between a first position in which the tubular wand
extends beyond the handle portion away from the flexible hose and a second position in
which the tubular wand extends beyond the handle portion inside the flexible hose.
The handle assembly according the invention has the advantages of the prior art in that
it is integral with the vacuum cleaner and does not requires separately stored parts to be
assembled together before use, and in that the handle portion can easily be gripped and
manoeuvred during "above-the-floor" cleaning. In addition, however, the time-
consuming and awkward task of removing the wand handle and reversing its orientation
no longer needs to be carried out in order to achieve this. The handle assembly
according to the invention is thus easier to operate and more reliable than the known
assemblies.
In a preferred arrangement, the handle portion carries a moveable cap which is arranged
to cover an end of the tubular wand when the tubular wand is in the second position.
Preferably, the moveable cap is mounted on the handle portion in a snap-fit manner.
More preferably, the moveable cap is moved into an open position by the tubular wand
when the tubular wand is moved from the second position to the first position. This
arrangement is a simple but effective way of providing a cover for the end of the wand
when the handle portion is being used as a handle in the upright mode..
In a further preferred embodiment, the tubular wand is held in the first position by a
releasable catch mechanism located in the handle portion. Preferably, the releasablc
catch mechanism comprises a catch which interengages with a detent in the tubular
wand, and inclined facing surfaces located on the handle portion and the catch, the
arrangement being such that an axial force applied to the tubular wand will urge the
catch into the detent. This mechanism ensures that, when the handle assembly is being
used for "above-the-floor" cleaning, any forces applied to the tubular wand which
would encourage it to move from the first position to the second position in fact urge the
catch further into engagement with the detent. This is essentially, therefore, a self-

locking mechanism and will reduce the risk of the tubular wand becoming inadvertently
released from the first position.
Other preferable and advantageous features of the invention are set out in the subsidiary
claims.
An embodiment of the invention will now be described with reference to the
accompanying drawings in which:

vacuum cleaner shown in Figures 1 and 2 and showing the handle assembly in the first
position;
Figure 4 is a view similar to Figure 3 but with the handle assembly shown in the second
position;
Figure 5 is a schematic sectional view through a part of the wand handle of Figures 3
and 4;

Figures 3 and 4; and
Figures 7(a), 7(b) and 7(c) are sequential views of the vacuum cleaner of Figure 1
illustrating the use of the handle assembly according to the invention.

A vacuum cleaner incorporating a handle assembly according to the invention is shown
in Figure 1. The upright vacuum cleaner 10 shown in Figure 1 has a main body 12
which includes a motor casing 14, supporting wheels 16 and dirt- and dust-separating
apparatus 18. The vacuum cleaner 10 also has a cleaner head 20 and a handle assembly
30. In the embodiment shown, the dirt- and dust- separating apparatus 18 comprises a
cyclonic arrangement but this could readily be replaced by a filter, a bag or a
combination of different known separation devices. The nature of the dirt- and dust-
separating apparatus 18 is not material to the present invention.
It will be understood that, in normal upright use, the vacuum cleaner 10 is manoeuvred
over a surface to be cleaned (a floor surface) whilst the motor causes dirty air to be
sucked into the cleaner 10 via the cleaner head 20. The dirty air is passed to the dirt-
and dust-separating apparatus 18 where the dirt and dust is extracted and clean air is
expelled to the atmosphere.
Figure 2 shows the vacuum cleaner 10 with the handle assembly 30 separated from the
main body 12. The handle assembly 30 comprises a hose 40 having a first end 42 and a
second end 46, a tubular wand 50 and a handle portion 60. The first end 42 of the hose
40 is normally connected to the main body 12 behind the motor casing 14. The upper
end 46 of the hose 40 is connected to the handle portion 60. Both of these connections
are preferably releasable connections to facilitate maintenance and repair. The tubular
wand 50 is slidably mounted in the handle portion 60 as will be described in more detail
below.
Figure 3 shows the handle assembly 30 in detail, although not to scale. The hose 40 is a
sprung hose and is ideally (but not essentially) of sufficient length to enable a full flight
of stairs to be cleaned with the vacuum cleaner main body 12 remaining at the foot of
the stairs. The first end 42 of the hose 40 has a collar 43 overmoulded or otherwise
securely fixed thereto with at least one resilient catch 44 incorporated therein. The
resilient catch 44 co-operates with a recess (not shown) in a socket on the main body 12
in which the first end 42 of the hose 40 is received. The catch 44 and recess together

form a releasable connection between the first end 42 of the hose 40 and the main body
12. This type of connection is well known and similar types of releasable connection
would be equally suitable for use in this application.
The second end 46 of the hose 40 has a similar releasable connection formed by a
resilient catch 48 moulded into a collar 47 which is overmoulded or otherwise securely
fastened to the second end 46 of the hose 40. However, in the case of the second end 46
of the hose 40, the resilient catch 48 is arranged to be received in a recess or aperture 49
moulded into the lower end of the handle portion 60. Again, the type of connection
formed by the catch 48 and the recess 49 is well known and could be replaced by
another type of connector having similar functionality.
The handle portion 60 will now be described in detail. The handle portion 60
essentially comprises a tubular part 62 having open ends 64, 66. The lower end 64 of
the tubular part 62 includes the recess or recesses 49 which receive the resilient catch or
catches 48 at the second end 46 of the hose 40. The internal diameter of the tubular part
62 is dimensioned so that the tubular wand 50 is able to slide within the tubular part 62.
A gripping handle 68 is integrally moulded or is otherwise fixedly attached to a side
wall of the tubular part 62 and extends laterally therefrom. Ideally, the gripping handle
68 has a first gripping area 68a which is designed for use when the vacuum cleaner 10 is
being used for upright cleaning and a second gripping area 68b which is designed for
use when the vacuum cleaner 10 is being used for "above-the-floor" cleaning.
A cap 70 is pivotably mounted on the tubular part 62 at the upper end 66 thereof. The
cap 70 is moveable between a generally horizontal closed position and a generally
vertical open position. The cap 70 has a generally circular shape when viewed from
above and has a number of bleed holes through which air is able to pass if required. In
the position shown in Figure 3, the cap 70 covers the upper end of the tubular wand 50,
although the bleed holes allow air to be drawn into the tubular wand 50 whilst
simultaneously preventing large objects from being drawn into the vacuum cleaner 10.

The cap 70 is mounted on the upper end of the tubular part 62 by the engagement of two
opposed pivot pins (formed on the upper end 66 of the tubular part 62) in corresponding
recesses 72 formed in the cap 70 (see Figure 6). The recesses 72 are formed in lugs 74
which project rearwardly from the main part 76 of the cap 70. The lugs 74 are formed
from a resilient plastics material and lead-in channels 77 are provided between the
apertures 72 and the lower edge of each lug 74. This arrangement allows the cap 70 to
be attached to the tubular part 62 in a snap-fit manner. Shapings (in the form of a
protrusion formed on each lug 74 next to each aperture 72 and co-operating profiled
channels formed in the tubular part 62 next to the pivot pins) allow the cap 70 to be
urged into one of two definite positions: either the cap 70 is urged into the horizontal
position shown in Figure 3 or it is urged into the substantially vertical position shown in
Figure 4.
The underside of the main part 76 of the cap 70 carries a depending portion in the shape
of a rib or fin 78. This rib or fin 78 has a contact surface 79 on the side of the rib or fin
78 facing the lugs 74. The purpose of the rib or fin 78 will be described below.
The tubular wand 50 is arranged inside the tubular part 62 of the handle portion 60. The
tubular wand 50 has rounded upper and lower ends 52, 54. The diameter of the tubular
wand 50 is such that it will fit with clearance inside the interior of the tubular part 62
and also inside the hose 40. The tubular wand 50 has a groove 56 formed in its outer
surface near the lower end 54 thereof. This groove 56 co-operates with a catch
mechanism forming part of the handle portion 60 as will be described in more detail
below. The upper end 52 of the tubular wand 50 is dimensioned so that it is able to
receive floor tools and accessory tools (not shown) which are intended to be used with
the vacuum cleaner 10 during "above-the-floor" cleaning. The length of the tubular
wand 50 is such that, when the cap 70 is in its horizontal position and the hose is in its
relaxed (shortest) state, the tubular wand 50 extends between the cap 70 and the collar
43 at the first end of the hose 40.

A groove (not shown) extends longitudinally along the entire length of the tubular wand
50 on the side thereof facing the gripping handle 68. A small protrusion (also not
shown) located on the interior of the tubular part 62 projects into the groove to prevent
the tubular wand 50 from rotating about its longitudinal axis with respect to the handle
portion 60.
The catch mechanism forming part of the handle portion 60 is shown more clearly in
Figure 5. Mounted in an annular recess 63 inside the tubular part 62 is an eccentric ring
80 which surrounds the tubular wand 50. The ring 80 has an enlarged shaped part 82
which carries an inwardly extending projection 84. The projection 84 is dimensioned so
as to engage with the groove 56 formed in the tubular wand 50 when the projection 84
and the groove 56 are in alignment. A spring 86 urges the ring 80 to the right as shown
in Figure 5 so that, when the projection 84 and the groove 56 are aligned, the projection
84 is moved into the groove 56. The spring 86 is seated in a small recess in the recess
63 and a tab on the shaped part 82 of the ring 80.
A handle release catch 90 is pivotably mounted on the tubular part 62 of the handle
portion 60 as shown in Figure 3. The handle release catch 90 carries a catch 92 which
co-operates with a recess on the main body 12 of the vacuum cleaner 10 so as to secure
the handle assembly 60 onto the main body 12 for storage and for upright cleaning. A
spring 93 urges the handle release catch away from the tubular part 62 and stop means
(not shown) limit the movement of the handle release catch 90 in that direction. Such
arrangements are well known. However, in the present embodiment of the invention, an
actuator 94 is provided on the rear surface of the handle release catch 90. The actuator
94 takes the form of a projection which projects rearwardly from the rear surface of the
handle release catch 90 towards the tubular part 62 of the handle assembly 30. An
opening 65 is formed in the tubular part 62 of the handle portion 60 opposite the spring
86. This opening 65 allows the actuator 94 to pass through the tubular part 62 and to
come into contact with the ring 82 when the handle release catch is pressed against the
action of the spring 93. It will thus be appreciated that the catch mechanism described
above is integral with the handle release catch 90. It will further be appreciated that the

catch mechanism is operated by the same action as that required to operate the handle
release catch 90 and thus release the handle assembly 30 from the main body 12 of the
vacuum cleaner 10.
It is to be noted that the shape of the enlarged shaped part 82 and the recess 63 are such
that the catch mechanism is self-locking. To that end, the recess 63 has inclined walls
63a adjacent the enlarged shaped part 82 and the facing walls 82a of the enlarged
shaped part 82 are also inclined. The result is that, when the projection 84 is engaged in
the groove 56, any axial forces applied to the tubular wand 50 (resulting in a small
amount of relative movement between the tubular part 62 and the eccentric ring 80) will
force the projection 84 further into the groove 56. This reduces the risk of the
projection 84 slipping out of the groove 56 and causing a sudden and unexpected
collapse of the handle assembly 30.
Figure 3 illustrates the relative positions of all of the components of the handle
assembly 30 when the handle assembly 30 is stored on the main body 12 of the vacuum
cleaner 10 or is being used for upright cleaning. The collar 43 is connected to the
socket (not shown) on the main body 12 and the catch 92 on the handle release catch 90
is engaged with the relevant recess on the main body 12 to secure the handle assembly
30 on the main body 12. In this position, the tubular wand 50 is in its first position
extending away from the handle portion 60 inside the hose 40. The hose 40 is in its
relaxed state and so is as short as possible in this configuration. The lower end 54 of the
tubular wand 50 reaches substantially to the first end 42 of the hose 40. The tubular
wand 50 is prevented from sliding out of the hose 40 by the fact that the collar 43 has an
internal diameter which is slightly smaller than the outer diameter of the tubular wand
50.
The upper end 52 of the tubular wand 50 extends through the tubular part 62 of the
handle portion 60 as far as the upper end 66. The cap 70 is in its horizontal position as
shown so that the otherwise open upper end 52 of the tubular wand 50 is covered to
prevent debris being sucked into the tubular wand 50.

Figure 4 illustrates the second configuration of the handle assembly 30 with the tubular
wand 50 in its second position. In this position, the tubular wand 50 has been slidingly
moved upwards relative to the handle portion 60 until the groove 56 becomes aligned
with the eccentric ring 80. The eccentric ring 80 is pressed into the groove 56 under the
action of the spring 86 to lock the tubular wand 50 relative to the handle portion 60.
(The position of the components of the catch mechanism are as shown in Figure 5.)
Because the lower end 54 of the tubular wand 50 is now located within the handle
portion 60, the hose 40 is free to flex and move in order to facilitate above-the-floor
cleaning.
As the tubular wand 50 is moved from the position shown in Figure 3 to the position
shown in Figure 4, the cap 70 is automatically pivoted from the generally horizontal
position shown in Figure 3 to the generally vertical position shown in Figure 4. This is
achieved simply by the movement of the tubular wand 50 with respect to the handle
portion 60. As the upper end 52 of the tubular wand 50 is moved towards the cap 70,
the upper end 52 comes into contact with the contact surface 79 of the rib or fin 78 on
the underside of the cap 70. The inclined shape of the contact surface 79 causes the cap
70 to rotate clockwise as the tubular wand 50 is moved upwardly, thus automatically
moving out of the path of the tubular wand 50. The shapings described above cause the
cap 70 to be held in the generally vertical position whilst the tubular wand 50 remains in
its second position.
In this configuration, the handle assembly 30 is highly suitable for above-the-floor
cleaning. Furthermore, the self-locking characteristics of the catch mechanism mean
that a reasonable amount of force can be applied to the wand 50 without the catch
mechanism failing and causing the handle assembly 30 to collapse. In this
configuration, it is expected (but not dictated) that the user will grip the handle
assembly 30 using the second gripping area 68b rather than using the first gripping area
68a.

When it is desired to return the handle assembly 30 to the first configuration, the user is
able simply to depress the handle release catch 90 towards the handle portion 60 against
the action of the spring 93. The actuator 94 presses against the eccentric ring 80 and
releases the projection 84 from the groove 56 in the tubular wand 50. The tubular wand
50 is thus able to slide within the handle portion 60 back to the first position as shown
in Figure 3. The hose 40 is again stored around the tubular wand 50 and the handle
assembly 30 can be re-attached to the main body 12 of the vacuum cleaner 10. The cap
70 is pressed into its generally horizontal position by the user.
Figures 7(a), 7(b) and 7(c) illustrate the intended steps to be taken when converting the
vacuum cleaner 10 from upright cleaning to above-the-floor cleaning. First, as shown
in Figure 7(a), the tubular wand 70 is extended upwardly with the handle assembly 30
otherwise still attached to the main body 12. Tools are attached to the upper end of the
tubular wand 50. The handle release catch 90 is then operated so as to release the
handle portion 60 from the main body 12 and the hose 40 is then extended to reach up a
flight of stairs or for other above-the-floor cleaning. To re-attach the handle assembly
30, the steps are simply reversed.
It will be appreciated that the invention is not intended to be limited to the specific
details of the embodiment described. Different arrangements and modifications will be
apparent to a skilled reader. For example, the configuration of the gripping areas could
be very different in design, as could the catches and the cap. Another possible
modification would be to provide a plastics moulded end portion on the upper end of the
tubular wand. Such an end portion would facilitate the attachment of tools and
accessories to the wand and would allow the dimensions of the upper end of the wand to
be varied without altering the construction of the main part of the tubular wand. A
convenient way of attaching such an end portion to the tubular wand is by way of a
plastic circlip seated in a groove moulded into the end portion and having projections
extending radially inwards to engage with apertures or detents formed in the aluminium
wand. Providing an end portion on the upper end of the tubular wand has an added
advantage in that, provided that the end portion is larger than the internal diameter of

the tubular part of the handle portion, the end portion will act as a stop which prevents
the upper end of the tubular wand from becoming inaccessible by sliding to a position
inside the handle portion or the hose.
