Description
The present invention relates to furniture components, to articles
of furniture and to methods of constructing furniture, and is
particularly, but not exclusively, applicable to fitted
furniture.
One important use of the present invention is for cupboards and
shelving for use as kitchen furniture or other storage furniture,
for example in offices, parts of homes other than kitchens,
hospitals, factories and stores.
Hitherto, fitted cupboards have usually been constructed by firstly
assembling a plurality of frame members, made for example of wood,
to form a frame, and then fitting a cladding for example plywood or
a wood and plastics laminate, onto the frame. The cupboards are
then fitted with the required doors, shelving and other accessories
and if necessary with a countertop.
The construction of the frame usually requires the formation of a
number of joints, which are time consuming and therefore relatively
expensive to produce. In addition, if the furniture is manufactured
in a factory for subsequent fitting in a room, it frequently
happens that the length of the furniture does not correspond to the
length of the wall along which the furniture is to be fitted.
Consequently, it is necessary to leave a gap at one or both ends of
the furniture or to cut to size special filler pieces for closing
such gaps.
Manufacturers of kitchen furniture have sought to mitigate this
disadvantage by manufacturing kitchen furniture in accordance with
predetermined modules, but of course, it frequently happens that
the rooms in which the furniture is to be fitted are not
constructed with dimensions corresponding to these modules.
It is indeed possible to avoid or at least reduce the use of filler
pieces by having the furniture specially constructed to the
required size on site, but in this case the economic advantages of
factory production are lost.
The present invention provides furniture components comprising at
least two walls having slots extending therethrough, and sheet
material the cross-section of which is shaped to fit slidably
through the slots to allow the sheet material to be inserted
through the slots and to extend between and at right angles to the
walls.
In use, the sheet material can be cut to the required length,
depending upon the length of a cupboard or cupboards or other
article of furniture to be assembled from the components. The
support is then inserted into the slots in the walls, and the walls
can be slid into position along the sheet material and secured
thereto.
Preferably, the sheet material, or at least a part thereof has a
generally U-shaped cross-section for forming the top, bottom and
back of a storage space in the furniture, in which case the slots
each have a correspondingly generally U-shaped configuration. For
example, the sheet material may be a channel-shaped extrusion of
plastics material or may be formed by vacuum welding or any other
suitable and convenient process from plastics material. The walls
may also be formed from plastics material, e.g., by injection
moulding. However, it is also envisaged that the walls and/or the
sheet material may be made of other materials, for example metal,
which may be painted or plastics coated metal, or wood, which may
be in the form of a moulded wood laminate.
The components preferably also include doors. For example, the
doors may be flexible "roll up" doors, which may be formed in one
piece of plastics material with transverse reinforcing ribs or bars
and which may be shaped to slide along grooves of generally
inverted U-shaped configuration formed in the walls. Alternatively,
the walls may be provided with pivoted or sliding doors. In any
case, it is preferable to make the doors so that they can readily
be cut to length on site.
In addition, a motor may be provided for opening and closing the
door.
A light fitting, for example, a fluorescent light fitting, may be
provided for mounting on the support, which may for example be
provided with a downwardly extending edge portion for concealing
the light fitting.
The walls may further be provided with grooves for slidably
receiving runners of drawers.
Suitable means may be provided for attaching the walls to the wall
of a building. Such means may, for example, comprise an L-section
support bracket for attachment to a building wall, the furniture
walls being provided with correspondingly shaped recesses or
notches enabling the furniture walls to be fitted into engagement
with the brackets. The brackets may be in the form of bars, which
may extend the length of the assembled furniture and assist in
rigidifying the latter.
The present invention further provides an article of furniture
comprising at least two walls having slots extending therethrough,
and sheet material the cross-section of which fits through the
slots, the sheet material being inserted through the slots and
extending between and at right angles to the walls.
The present invention still further provides a method of
constructing an article of furniture, which comprises the steps of
cutting sheet material to a desired length, fitting the cut sheet
material through slots in walls, sliding the walls along the sheet
material into required positions, and securing the walls in said
required positions to the sheet material.
The invention will be more readily understood from the following
description of a preferred embodiment thereof, given by way of
example with reference to the accompanying drawings, in which:
FIG. 1 shows a partly broken-away view, taken in perspective, of
kitchen furniture; and
FIG. 2 shows a view taken in perspective of the rear of part of the
furniture shown in FIG. 1.
The furniture illustrated in FIG. 1 comprises a wall-mounted
assembly, indicated generally by reference numeral 10, which
includes a plurality of storage cupboards, and a floor- and
wall-mounted assembly, indicated generally by reference numeral 12,
which also provides storage cupboards and which includes a
preformed plastic laminate counter-top 14.
The assembly 10, which is also illustrated in FIG. 2, is formed by
sheet material in the form of a generally U-shaped frame member 15,
which forms a rear wall 16, a top 17 and a bottom 18. The top 17
and the bottom 18 each merge smoothly at the rears thereof with the
rear wall 16, and are formed at the fronts thereof with downwardly
extending valence portions 20, 21, respectively.
The frame member 15 extends through four transverse walls 22.
Each of the walls 22 is formed with a slot 23 extending through the
whole thickness of the wall, the slot 23 having a shape which
matches the cross-section of the frame member 15, and allowing the
respective wall 22 to be slid along the frame member 15.
Each wall 22 is also formed on each of its opposite sides with a
groove 25 extending outwardly of the opening 23 through only part
of the thickness of the wall 22 and serving as a door guide
groove.
The assembly is provided with four doors, of which one is not
illustrated and the other three are indicated by reference numerals
27, 28 and 29, respectively. Each of these doors extends between an
adjacent pair of the walls 22 and is slidably guided in the grooves
25 of those two walls. Moreover, each of the doors is formed in one
piece from a flexible plastics material with transverse ribs and
can readily flex, in accordance with the shape of the slots 25,
when slid up or down in front of the channel frame member 15 to
open and close the respective cupboard. Stops 26 are provided at
the lower ends of the slots 25, at the front of the assembly 10, to
retain the doors in the slots 25.
The assembly 10 is also provided with adjustable shelves 30, which
are supported on conventional pegs projecting from openings in the
walls 22.
Beneath the valence portion 21 of the frame member 15, there are
provided fluorescent light fittings, of which only one is shown and
indicated by reference numeral 31. The light fitting 31 is
concealed by the valence portion 21 and serves to illuminate the
counter-top 14.
The assembly 10 is supported on a wall 32 of a room by means of
channel-shaped support rails or brackets 33 of L-shaped
cross-section, which engage in appropriately shaped recesses 34
(see FIG. 2) in the rears of the transverse walls 22.
The assembly 12 has transverse walls 122 formed with openings 123,
through which extends a frame member 115 of generally U-shaped
cross-section, and grooves 125 for roll-up doors of which only two
are shown and indicated by reference numerals 127, 128. It will
thus be readily seen that the construction of the assembly 12
resembles that of the assembly 10 in a number of respects. However,
the assembly 12 is secured to the wall 32 by only one support rail
133, and is supported on a floor 140 by means of a wooden beam 141.
The beam 141, as can be seen from the drawing, also supports bottom
131 of the frame member 115.
In addition, the assembly 12 is provided with drawers 142 having
runners (not shown) which slidably engage in horizontal slots 143
formed in the transverse walls 122. The drawers 142 are also
supported by horizontal portions of the doors 127, 128 extending
above top 117 of the frame member 115.
Preferably, electric motors (not shown) are provided for opening
and closing the doors of the assemblies 10 and 12. These electric
motors may for example be in engagement with the doors through
frictional drive discs or sprocket wheels, preferably via overload
clutches, and may be provided with automatic cutout circuitry to
prevent overheating of the electric motors if the doors should
become jammed.
The above-described assemblies are constructed as follows.
Firstly, the support rails 33 and 133 are cut to size, depending on
the length of the wall 32 or the desired lengths of the assemblies,
if these are for example to be less than that of the wall 32, and
the support rails 33 and 133 are then secured in position on the
wall 32. Similarly the beam 141 is cut to length and mounted on the
floor 140.
Next, the frame member 15 and 115 are cut to the appropriate
lengths, and the required number of transverse walls 22 and 122 are
fitted onto and slide along the frame members 15 and 115
respectively, until these walls are positioned at spacings
corresponding to the widths of the cupboards which it is desired to
form in the assemblies 10 and 12. The walls 22 and 122 may then be
secured in position relative to the frame members 15 and 115,
respectively, e.g., by inserting screws, dowels or other locking
members through the edges of the walls into engagement with the
frame members. At the same time, the roll-up doors are cut to
length, if necessary. The edges of the roll-up doors are then
fitted into the grooves 25 and 125, and the stops 29 are inserted
to retain the doors.
In this way, the assemblies can readily be constructed so as to
correspond in length to that of the wall 22 and to provide
cupboards of any required length.
Finally, the fluorescent light fittings 31, the counter-top 14, the
drawers 142 and the electric motors are fitted into position.
The above-described furniture components may of course be modified.
For example, if it is not intended to construct the assemblies so
as to extend the whole length of the wall 32, then at least one end
of each assembly may be provided with a transverse wall which is
slotted on one side only and presents, on its other side, an
aestethically pleasing flat uninterrupted surface. Alternatively, a
cover, for example of plastics laminate, may be provided, for
example, over the outer surface of an end wall 22 of one or each of
the assemblies as shown in FIG. 1.
Instead of employing roll-up doors as described above and
illustrated in the drawings, leaf doors, pivotally supported on the
transverse walls, or sliding doors sliding in channels secured, for
example, to the valences 20 and 21 may be employed. Alternatively,
the doors may be omitted if open shelving is required. partially
bya a) shaped part
The top, bottom and rear wall of each frame member described above
are formed in one piece, and shapes of the frame members
illustrated in the drawings have the advantage that the rear walls
are joined to the tops and bottoms by curved portions which obviate
corners which might act as dust and dirt-traps. However, for
facilitating manufacture and/or transportation and storage of the
components, it may be preferable to form the top, bottom and rear
wall as at least three separate, e.g., flat, components, and to
correspondingly modify the shape of the slots in the transverse
walls.
Yet another possibility would be to provide instead of a frame
member formed only of the top, bottom and rear walls, a support in
the form of a beam, e.g., of extruded plastics material and arcuate
cross-section, fitting into corresponding openings in the
transverse wall and formed with a longitudinal slot for receiving a
panel, which panel could, e.g., form the top, bottom or rear wall
of the storage space.
