Claims
What I claim as my invention is:
1. A demountable partition comprising: an upwardly-opening floor
channel on a floor; a downwardly-opening ceiling channel affixed to
the ceiling parallel to and above said floor channel, the depth of
the ceiling channel being substantially greater than the depth of
the floor channel and the ceiling channel having a pair of inwardly
extending lips defining a slot; a trim strip engaged in the ceiling
channel and having a width greater than the width of the slot; and
spring means housed in the ceiling channel above the trim strip for
biasing the trim stip into engagement with upper surfaces of the
lips; and panels having a thickness slightly less than the width of
the slot for sliding engagement in the ceiling channel between the
lips, each of the panels having respective upper and lower ends
engaged in the ceiling and floor channels, the upper ends of the
panels being engaged against the underside of the trim strip
whereby the trim strip is displaced upwardly of the lips and the
spring means is compressed to provide a downward force on the floor
channel, each of the panels being removable by displacing the panel
upwardly to further compress the spring means and thereby release
the lower end of the panel from the floor channel whereupon the
panel is removed from the ceiling channel by first moving the lower
end of the panel away from the floor channel and then lowering the
panels so that the upper end of the panel is removed from the
ceiling channel.
2. A demountable partition as claimed in claim 1 in which the
spring means comprises a plurality of coil springs in spaced-apart
relation with their axes vertical.
3. A demountable partition as claimed in claim 1 in which the
ceiling channel comprises a horizontally extending web,
spaced-apart upright side walls dependent from respective
longitudinal edges of the web, the lips being coplanar and
extending inwardly from respective lower ends of the side walls.
Description
This invention relates to a demountable partition of a type which
can be used to divide a large room into smaller units.
When designing office space, classrooms, and the like it is
convenient to have relatively large areas which can then be
sub-divided into rooms using demountable partitions. This has the
advantage that as needs change, the partitions can be moved to
different locations to re-arrange the layout of the rooms. The
principle requirements of such partitions are that they should be
assembled and dis-assembled easily and with a minimum use of tools.
Also each part of the partitions should be of a size which is
convenient for storage.
A number of demountable partitions are available. These fall into
three main types, a first of which includes fixed upper and lower
channels in which panel members are mounted relatively loosely.
This type tends to vibrate and the channels must be disconnected
and moved to a new site when the partition is to be relocated. A
second type uses wedges for attaching the panels to the channels to
prevent vibration and to more positively locate the panels. Here
again, the difficulty is that the channels must be disconnected
from floor and ceiling before they can be re-positioned. In the
third type, the panels are mounted resiliently in the channels so
that the vibration problem is substantially eliminated.
According to a particular preferred embodiment of the present
invention, a demountable partition is provided having an upper or
ceiling channel and a lower or floor channel arranged in vertical
alignment. The channels are spaced-apart sufficiently to receive
wall panels which are adapted to be engaged in the channels and
biased downwardly by spring means housed inside the ceiling
channel. The spring means is contained inside the channel by a trim
strip which in turn bears against the top of the partition panels.
The spring biasing means is adapted to provide sufficient downward
force on the panel to hold the floor channel in frictional
engagement on a floor. When the partition is to be repositioned,
panels are first removed from the channels and then the floor
channel is lifted off the floor leaving the ceiling channel in
place. The trim strip is forced downwardly over the mouth of the
ceiling channel to provide a more pleasing appearance and to
disguise the purpose of the ceiling channel. Numerous channels are
built into the ceiling of the area in which partitions could be
used so that a modular room structure can be built up using the
demountable partitions.
The invention will be better understood with reference to the
drawings, wherein:
FIG. 1 is a perspective view of a demountable partition being
constructed in a room;
FIG. 2 is a sectional view on lines 2--2 of FIG. 1;
FIG. 3 is a sectional view on lines 3--3 of FIG. 1;
FIG. 4 is a sectional view on lines 4--4 of FIG. 1;
FIGS. 5, 6 and 7 are sectional views of alternative floor
channels;
FIG. 8 is a sectional view of an alternative ceiling channel;
and
FIG. 9 is a sectional side view of a further alternative ceiling
channel.
Reference is first made to FIG. 1 which shows an upright
demountable partition 10 in a room 12 and extending at right angles
to a wall 14 between the floor 16 and ceiling 18. The partition 10
includes an upper or ceiling channel 20 in vertical alignment with
a lower or floor channel 22 and panels 24, 24', 24" removably
engaged in the channels 20, 22. The ceiling channel 20 is attached
to the ceiling 18 by glue, nails, screws or the like whereas the
channel 22 is held in place on the floor 16 by frictional
forces.
As seen in FIG. 2, the ceiling channel 20 has spaced-apart
generally parallel side walls 26, 28 extending downwardly from an
upper web 30 and terminating at respective inwardly-turned lips 32,
34. The lips 32, 34 define a slot 36 for receiving upper ends of
the panels 24, (FIG. 1). A trim strip 38 is located in the channel
behind the lips 32, 34 and biased towards the slot 36 by a
plurality of spaced-apart coil springs 40 to effectively close the
slot 36 and improve the appearance of the channel when the panels
24 are removed. The floor channel 22 is shallower than channel 20
but is similar in shape to channel 20. Channel 22 has a web 42,
upright side walls 44, 46 and inwardly turned lips 48, 50 which
define a slot 52 for receiving lower ends of panels 24. The lips
48, 50 are provided to strengthen the channel and to present a
similar appearance to the upper channel 20. If preferred however
the floor channel 22 may be made without the lips 48, 50 in which
case the side walls 44, 46 would define slot 52. Also any desired
ornamental shape can be used consistent with providing the slot 52.
The reason for the difference in depth between channels will be
explained later in the disclosure. The springs 40 are attached to
the web 30 by gluing or by any other conventional means.
Where the ceiling channel 20 is to be screwed or nailed to the
ceiling 18 the trim strip is positioned behind lips 32, 34 after
screwing the channel to the ceiling. The strip is positioned by
slipping a longitudinal edge between the spring and a lip and then
rotating the strip transversely against the springs to enter the
other longitudinal edge behind the other lip. Upon releasing the
strip, the springs force the strip into engagement with the lips.
If required, glue can be used to more positively locate the strip
on the springs.
Reference is now made to FIG. 3 which shows the ceiling channel 20
and floor channel 22 with a panel 24 in place in the channels.
Springs 40 are partially compressed and the trim strip 38 is
displaced upwardly off the lips 32, 34. The weight of the panel 24
together with the downward force exerted by springs 40 are
sufficient to frictionally locate the lower channel 22 on the floor
16.
Adjacent panels 24, 24' are interengaged as shown in FIG. 4 to more
positively locate one panel in relation to the next panel and to
limit possible vibrational noises. The panels shown in FIG. 4 are
typical of any pair of adjacent panels.
Panel 24 has an upright end face 53 on which is formed or attached
a tongue 54. The other upright end face of panel 24 is similar to
end face 55 on panel 24' which defines a groove 56 for slidably
receiving the tongue 54. The groove can be of any depth and may be
deepened as shown to house electrical services having an outlet 57
connected by an opening 58 to the groove 56. When not required the
outlet is covered by a decorative plate. The other end face of
panel 24' is similar to the end face 53 of panel 24. In general
each panel has a tongue at one upright end face and a matching
groove in the other upright end face.
To assemble a partition, a floor channel 22 is laid on the floor 16
in vertical alignment with a ceiling channel 20. Where many
variations are required, the ceiling will be equipped with as many
ceiling channels as may be necessary. Next a panel 24 is lifted
vertically to engage an upper end in ceiling channel 20. The
ceiling channel has sufficient depth to permit the user to push the
panel 24 upwardly until the lower end of panel 24 can be dropped
into floor channel 22. The springs 40 then bias the panel 24
downwardly to aid in holding channel 22 in place on the floor.
Further panels 24 are then added as required and pushed into
engagement with adjacent panel 24 to engage the tongue 54 into
groove 56 (FIG. 4). If preferred, each of the panels 24 can be
entered into channels 20, 22 from one end and pushed along the
channels into the desired position. The partition can be
disassembled by reversing the above assembly procedure.
Reference is now made to FIGS. 5, 6 and 7 which illustrate three
alternatives for lower channel 22 (FIG. 1). As seen in FIG. 5, a
channel 59 is provided having extruded serrations 60 on its
underside for gripping a carpet 61. The serrations are positioned
to prevent transverse displacement of the channel 59 across the
surface of the carpet 61. A more positively positioned floor
channel is shown in FIG. 6. This second alternative includes a
floor channel 62 which has a plurality of pins 64 spaced-apart
along the channel 62 and extending downwardly from a web 66.
Ferrules 68 are set in floor 70 and spaced-apart such that they
receive the pins 64 when the channel is to be located on the floor
70. In this arrangement, ceiling channels are placed on the ceiling
at intervals in positions where partitions may be required and
corresponding rows of ferrules 68 are positioned in vertical
alignment with the ceiling channels in the floor 16. When a
partition is to be assembled the channel 62 is placed with the pins
64 in corresponding ferrules 68 and then the panels 24 are inserted
in the channels 20, 22.
FIG. 7 shows a third alternative floor channel 72 having the usual
lips 74, 76 together with a pair of coplanar ribs 78, 80 for
engaging the underside of a panel 24 (FIG. 1). When the channel is
positioned against the ribs 78, 80 there is a duct 82 formed below
the panel 24 for containing electrical services and the like. The
electrical connections can be made by bringing the conductors from
the duct 82 upwardly between the panels in the grooves 56 (FIG. 4).
The underside of the channel 72 has a friction pad 83 of rubber or
any other suitable material for increasing the frictional grip
between the channel 72 and the floor. This pad can be used whenever
required and with other embodiments of the floor channel.
A further embodiment of the upper channel 20 is shown in FIG. 8. A
ceiling channel 84 is adapted to form an integral part of a
suspended ceiling 86 which is attached by a suspension member 88 to
a roof 90. Screws 92 pass through a web 94 in a ceiling channel
member 84 and into member 88 to attach the channel 84. The channel
is similar to channel 20 (FIG. 2) but for outwardly extending
flanges 96, 98 which support respective acoustic ceiling panels
100, 102 of the suspended ceiling 86. Channels 84 are arranged to
form rectangular spaces in which the ceiling panels 100, 102 are
positioned. The resulting suspended ceiling 86 presents a pleasing
appearance and can be used to receive panels such as panels 24,
(FIG. 1) for forming rooms as required.
Reference is now made to FIG. 9 which shows an alternative for
springs 40 (FIG. 2). In this figure a web 104 has a leaf spring 106
attached by a rivet 108. A trim strip 110 is biassed downwardly by
the spring 106. This type of spring is suitable in some situations
but coil springs are preferable because their change in length
takes place transversely of the channel whereas the leaf spring
would become axially longer as panels are inserted in the ceiling
channel. Consequently the leaf spring must be axially shorter than
the extent of the ceiling channel if the ends of the spring are not
to project beyond the ends of the channel when the panels are in
place in the ceiling channel.
Because of the tongue and groove arrangement between adjacent
panels, the panels must be moved along the channels before they can
be removed. If it is desired to prevent disassembly a locking
device can be inserted into one or both of the ceiling and floor
channels to prevent sliding movement of the panels. The locking
device can take any convenient form and be operated by a key.
Each of the channels and trim strips described is preferably of
sheet metal formed into the required shape or of extruded aluminum.
However a suitable plastic can also be used. Each of the panels 24
is of plywood faced with plastic or painted but any other suitable
material can be used.
