[0001] The invention relates to an assembly comprising a chair and a shampoo basin for washing
hair, the shampoo basin having a neck recess and being adjustably mounted on a pillar.
[0002] Such an assemly, known from practice, is used for washing hair, for instance in a
hairdressing salon. In the known assembly, the front side of the shampoo basin facing
the customer is provided with a neck recess for connecting to and around the customer's
head in an optimum manner. During the washing of the hair, the hairdresser stands
at the back of the shampoo basin. To enable the shampoo basin and, accordingly, the
neck recess to be adjusted in height, depending on the length and sitting position
of the customer in question, the shampoo basin is connected to the pillar so as to
be pivotable or tiltable forwards and backwards about a horizontal axis.
[0003] However, this construction has the drawback that it is laborious to adjust the shampoo
basin to the height position of the head of a customer. Also, owing to the shampoo
basin being pivoted to the front or rear side, the lowest point of the shampoo basin,
where the water discharge is normally located, is displaced, as a consequence of which
the emptying of the shampoo basin is no longer guaranteed. When the shampoo basin
is pivoted forwards to an extreme extent, for instance in the case of an extremely
small customer, there is even a chance that the water contained in the shampoo basin
overflows via the edge at the side of the neck recess.
[0004] The object of the invention is to provide an assembly of a chair and a shampoo basin
of the type referred to in the opening paragraph, wherein the drawbacks mentioned
are avoided.
[0005] In accordance with the invention, this is realized in that the shampoo basin is mounted
on the pillar in a substantially stationary position and the pillar consists of at
least two parts, movable relative to each other, the arrangement being such that the
shampoo basin is adjustable in height relative to the chair. Preferably, the shampoo
basin is arranged in a horizontal position.
[0006] By the features according to the invention, an assembly is provided wherein the shampoo
basin can be brought into a proper height position for the customer in a quick and
easy manner, while it remains substantially in an aligned position, more in particular
in a horizontal position, independently of the body length and position of the customer.
Also, an optimum water discharge is realized in all height positions of the shampoo
basin, with the chance of the shampoo basin running over being prevented and a hygienic
use of the assembly of chair and shampoo basin being guaranteed.
[0007] In order to provide a hygienic assembly which is easy to operate, the at least two
pillar parts are arranged for telescopic inward and outward relative movement.
[0008] A particularly easy sitting position for the customer is realized when the shampoo
basin is adjustable in a pillar direction at an angle of inclination of, for instance,
between 45° and 65°, preferably 57°.
[0009] To prevent a displacement of the chair relative to the shampoo basin, it is preferred
that the pillar is connected to the chair, with the back support, in a particularly
simple embodiment, having the same angle of inclination as the direction along which
the shampoo basin is adjustable. For carrying out operations other than washing hair,
such as for instance blow-drying or cutting hair, it may be advantageous if the angle
of inclination of a back support of the chair is settable relative to that of the
pillar.
[0010] There are various possibilities for enabling height adjustment of the shampoo basin,
for instance by a displacement in steps or a continuous movement by means of a screw
spindle. For a particularly easy and accurate height adjustment, the assembly comprises
a gas spring for moving the two pillar parts along each other.
[0011] Hereinafter, the invention will be specified on the basis of an exemplary embodiment
of an assembly of a chair and a shampoo basin, with reference to the accompanying
drawings, wherein:
Fig. 1 is a side elevation of an assembly according to the invention; and
Fig. 2 is a side elevation of an assembly according to the invention wherein the shampoo
basin is shown in an elevated position.
[0012] In the Figures, corresponding parts are designated by identical reference numerals.
Fig. 1 is a side elevation of an assembly comprising a chair 1 and a shampoo basin
2. The shampoo basin 2 has a recess 3 for the neck portion of a customer 4 with the
hair to be washed. The shampoo basin 2 is mounted horizontally on a pillar 5. The
pillar 5 consists of two parts, a base portion 6 and a sliding portion 7, telescopically
movable relative to each other. The bottom side of the shampoo basin 2, mounted on
the sliding portion 7, comprises a fastening means 11. Arranged in the inner space
of the base portion 6 is a gas spring 8, which can be operated by a hairdresser in
a known manner, not further shown. A piston rod 10 movable in a cylinder 9 is coupled
to the fastening means 11. The chair 1 is mounted on an extension 12 fixedly connected
to the pillar 5. The back support 13 is positioned at the same angle of inclination
α, preferably 57°, as the pillar 5. In a manner not further shown, the back support
13 is adjustable about a horizontal axis. Also disposed on the shampoo basin 2 is
an extendible water tap 14, known per se. The operation of this assembly of chair
and shampoo basin, shown in Fig. 1 in the lowest position of the shampoo basin 2,
is further explained with reference to Fig. 2.
[0013] Fig. 2 is a side elevation of the assembly according to the invention, with the pillar
5 shown in a telescoped-out position for a relatively long customer. For this purpose,
the gas spring 8 is put into action, and the piston rod 10 is displaced relative to
the cylinder 9 so that the shampoo basin 2 is brought into a higher position, with
the shampoo basin retaining its substantially horizontal position. As appears from
Fig. 2 in comparison with Fig. 1, a large customer takes up the same sitting position
as a small customer. A further advantage is that the hair to be washed of a customer
is always in the same horizontal working plane as the accessories to be used by a
hairdresser, such as for instance the water tap 14 placed on the shampoo basin 2.
However, the lowest point of the shampoo basin 2 always remains the lowest point,
regardless of a particular height position, which guarantees that during an adjustment
of the height position, the discharge of the water from the shampoo basin does not
cause any problems.
[0014] It is readily understood that still many modifications and variants are possible
within the framework of the invention as laid down in the appended claims. For instance,
the single gas spring may be replaced by two juxtaposed gas springs, which virtually
eliminates the tilting danger during height adjustment of the shampoo basin. Further,
instead of pillar parts that can be telescopically slid into and out of each other,
it is possible to use two spaced-apart pillar parts which are interconnected by an
elastic, optionally concertina-shaped part, and which can be moved relative to each
other for instance by means of a screw spindle. By designing the seat and the back
support of the chair so as to be adjustably pivotable relative to each other or to
be jointly adjustably pivotable relative to the extension 12 about a horizontal axis,
the customer, after the completion of the washing treatment, can be brought into a
more vertical position for carrying out further treatments. For this purpose, it may
also be advantageous to dispose the seat with support so as to be pivotable about
a vertical axis, so that, after the washing treatment, the chair with the customer
can be turned through for instance 90° to a position outside the range of the shampoo
basin.
