[0001] According to the present invention, there is provided an attachment for a vacuum
cleaner, comprising a suction head for connection to a vacuum cleaner, the suction
head having a plurality of channels for each communicating with a vacuum cleaner,
each channel leading to a respective suction opening in the suction head, and means
for selecting one of the plurality of channels for connection to the vacuum cleaner.
[0002] For a better understanding of the present invention and to show how the same may
be put into effect, reference will now be made, by way of example, to the accompanying
drawings, in which:
FIGURE I is a perspective view of one vacuum cleaner attachment embodying the invention;
FIGURE 2 is a vertical cross-sectional view of the vacuum cleaner attachment of Figure
I;
FIGURE 3 is a perspective view of another vacuum cleaner attachment embodying the
invention; and
FIGURE 4 is a vertical cross-sectional view of the vacuum cleaner attachment of Figure
3.
[0003] Referring firstly to Figures I and 2, there is shown one form of attachment for a
vacuum cleaner in accordance with the invention.
[0004] As shown in Figures I and 2, the attachment comprises a suction head having a tubular
portion I for attachment to the pipe of a barrel vacuum cleaner (not shown) or a pipe
attachment of an upright vacuum cleaner (not shown).
[0005] The tubular portion I is connected to a flared rectangular skirt 2 constituting a
cleaning head of the attachment, which skirt has a downwardly extending flange. The
underside of the flared skirt 3 is divided into three channels 4 by two partitions
5. Each channel 4 communicates with a respective suction opening 6 provided in the
flange 3 of the skirt 2, one opening being provided on a front face 3a of the flange
of the skirt and a respective opening being provided on each side face 3b of the flange
of the skirt. Each channel 4 may be individually brought into communication with the
tubular portion by moving a respective stopper or closure member 7 received in an
aperture 8 formed on the skirt out of the channel 4. Similarly each channel 4 may
be closed by moving the respective stopper 7 into the channel 4.
[0006] Thus, when the attachment is connected to a vacuum cleaner, the arrangement enables
the suction effect of the vacuum cleaner to be communicated to one or more of the
three channels 4 so that the attachment may be used, for example, for cleaning right
up to the skirting boards of a room.
[0007] Figures 3 and 4 illustrate another form of vacuum cleaner attachment in accordance
with the invention, which attachment comprises a tubular shaft 10 adapted to be connected
at an upper end thereof to a vacuum cleaner suction hose (not shown) by a standard
attachment bush II. The shaft 10 has a bend forming an elbow 12 between the ends of
the shaft.
[0008] A lower end portion 13 of the shaft 10, which may be closed by an end wall 14, is
rotatably received in a tubular socket 15 formed in an elongate skirt 16 constituting
a cleaning head of the attachment, the socket 15 extending transversely of the skirt
16 at the top of the skirt.
[0009] The skirt 16 has an elongate top wall 17 which arrives upwardly from its ends to
a central part cylindrical portion 18 which defines part of the socket 15 within the
skirt. Vertical side walls 19 extend downwardly from the longitudinal edges of the
top wall 17 to define a housing whcih is open downwardly and has downwardly inclined
suction openings 20 at its ends.
[0010] A pair of partitions 21 conforming to the shape of the top wall 17, and extending
between the side walls 19, extend upwardly from the lower edges of the respective
side walls to the socket 15, so as to define left and right subsidiary suction channels
22 overlying a main suction channel 23. The subsidiary channels 22 communicate with
the end openings 20 of the skirt 16 and the main channel 23 is downwardly open at
suction opening 25.
[0011] The end portion 13 of the shaft 10 is formed in its cylindrical wall with a suction
inlet 26 which can be selectively placed in communication with each of the channels
22 and 23 by rotating the shaft 10 in the socket 15 into the appropriate angular position.
Rotation of the shaft 10 within the socket 15 is facilitated by the elbow 12 which
enables the shaft to be swivelled without undue effort.
[0012] With the shaft 10 in the position shown in Figure 4, the suction inlet 26 is connected
to the main channel 23 for normal, downward suction through opening 25.
[0013] With the shaft 10 in the position shown in Figure 3 or on the equivalent left hand
position, the suction inlet 26 is connected to the corresponding subsidiary channel
22 for sideways suction through openings 20 for use in cleaning adjacent to skirting
boards and in other obstructed areas.
[0014] It is envisaged that suitable detent means (not shown) may be provided to retain
the end portion is of the shaft in a selected angular position with its suction inlet
in commuication with a selected one of the channels.
I. An attachment for a vacuum cleaner, comprising a suction head for connection to
a vacuum cleaner, the suction head having a plurality of channels for each communicating
with a vacuum cleaner, each channel leading to a respective suction opening in the
suction head, and means for selecting at least one of the plurality of channels for
connection to the vacuum cleaner.
2. An attachment according to Claim 1, wherein the plurality of channels comprises
a pair of subsidiary channels overlying a main channel.
3. An attachment according to Claim I or 2, wherein the suction head comprises a skirt
defining the channels and a tubular portion extending from the skirt for connection
