Description of Invention
[0001] This invention relates to partitions comprising demountable panels.
[0002] Such partitions permit of versatility in the subdivision of rooms into smaller units,
for example, offices or for industrial purposes by means of partitions which are capable
of re-arrangement if it is desired to change the configuration of the smaller units.
[0003] It is becoming common to make the partitions from prefabricated elements supplied
to site. For example, "solid" panels, door panels, window panels or the like are manufactured
in a factory and are then transported to site where they are mounted in interconnected
juxtaposition to form a partition. Such partitions must satisfy acoustic insulation
requirements and, in at least some constructions, prevent a fire spreading from one
side of the partition to the other. It is, therefore, necessary to connect the panels
together and hitherto this has been done by using connector pieces between adjacent
edges of the panels and subsequently covering these connector pieces with cover strips.
Generally, a relatively large space has been provided between the edges of adjacent
panels to enable access into the joint in order to perform the connection.
[0004] According to one aspect of the present invention we provide a partition comprising
a pair of juxtaposed dismountable panels, a connecting member mounted on one of the
panels and moveable between an inoperative position in which the panels may be moved
into and out of juxtaposition and an operative position in which the panels are connected
together in juxtaposition.
[0005] According to a second aspect of the invention we provide a partition comprising a
pair of juxtapositioned dismountable panels wherein one edge of one panel is provided
with a plurality of slots to receive first limb of a bracket, the bracket having a
second limb which extends generally perpendicular to the first limb so as to extend
between adjacent edges of the juxtaposed panels and project outwardly of a side surface
of the panels.
[0006] According to a third aspect of the invention we provide a partition wherein one of
the panels is a twin glazing panel comprising a pair of sub units, each sub-unit comprising
a glazed frame and the sub-units being disposed so that the glazing is in face to
face spaced relationship and means are provided to maintain the sub-units in said
relationship.
[0007] According to a fourth aspect of the invention we provide a partition wherein one
of the panels comprises a junction panel comprising at least two inclined limbs, the
junction between the limbs being permanent and the edges of the limbs being provided
with connection means whereby the edges may be connected to other panels of the system
in the same manner that the other panels are themselves connected together.
[0008] A demountable partition will now be described by way of example with reference to
the accompanying drawings wherein
FIGURE 1 is an exploded fragmentary perspective view of a bottom part of a partition
embodying the invention, and
FIGURE 2 is a fragmentary perspective view showing a top part of the one panel of
the partition shown in Figure 1.
FIGURE 3 is a fragmentary perspective view showing a top part of the other panel of
the partition shown in Figure 1, and
FIGURES 4a-4e are diagramatic horizontal cross-sectional view showing various configuration of
junction panel.
FIGURE 5 is an exploded fragmentary perspective view of a bottom part of an alternative
partition embodying the invention.
[0009] Referring to figures 1 to 4 of the drawings, a partition is indicated generally at
10 and comprises a plurality of dismountable panels arranged in edge to edge juxtaposition.
In Figure 1 part of two such panels 11, 12 is shown. The partition may comprise any
desired number of identical panels and the partition may extend rectilinearly or through
any desired angular configuration therebeing appropriate means provided at the corners.
The partition may comprise panels of any desired type for example "solid" panels,
glazed panels or door panels. In the illustrated example the panel 11 is a twin glazed
panel whilst panel 12 is a "solid" panel.
[0010] The preferred construction of the panels 11 and 12 will be described hereinafter
although other constructions may be provided if desired but irrespective of the detailed
construction, the panels are provided with mullion members which extend vertically
along the two opposite vertical edges of the panels. Thus, a first edge 13 and a second
edge, not shown, of the one panel 11 is provided with a first mullion member 14 whilst
a first edge, not shown, and a second edge 15 of the other panel 12 is provided with
a second mullion member 16. The precise constructional details of the mullion members
may vary from panel to panel particularly where the panels are of different type,
as will be more apparent from a detailed description of the panel constructions hereinafter,
but the mullion members are functionally similar.
[0011] For convenience the structure at only the first edge 13 of the one panel will now
be described, the second edge thereof being the same. The first mullion member 14
is provided with a plurality of pairs of slots 17 at equally spaced positions along
the height of the mullion member. A first generally channel shaped member 18 is attached
to the first mullion member 14 by means of two pairs of pressed-out hook parts 19
which are received within the slots 17 of two pairs of slots and by means of two self-tapping
securing screws 20 which pass through apertures 21 in a base part 22 of the channel
member 18 and are threadedly engaged in apertures 23 of the first mullion member 14.
[0012] If desired a different number of pairs of hook parts and securing screws may be provided.
[0013] The first generally channel shaped member 18 has out-turned lips 24 at the free ends
of the limbs 25 thereof. Movably mounted between the limbs 25 is a channel shaped
connecting member 30 having a base 31 and spaced limbs 32. The spacing of the limbs
32 is such that they are a sliding fit within the limbs 25 of the first generally
channel shaped member 18.
[0014] The base 31 of the connecting member 30 is provided with three apertures 33 at spaced
positions along its length, only one of which is shown in Figure 1, whilst a corresponding
number of square apertures 34 are formed in the base 22 of the first member 18. A
clip 35 having a U-shaped portion 36 and a downwardly depending leg 37 is positioned
so that the U-shaped part 36 is engaged over the edge 38 of the aperture 34, therebeing
a tag pressed out of the limb of the U-shaped part 36 which is connected to the downwardly
depending leg 37 which engages in a slot 39 formed in the base 22 to retain the clip
in position. The leg 37 overlies the base 31 of the connecting member 30 and engages
therewith in the region indicated at 40 and thus resiliently biases the base 31 of
the connecting member 30 against the base 22 of the first generally channel shaped
member 18. A single coil tension spring 41 is engaged between a tag 42 formed on the
base 31 of the connecting member 30 and a tag 43 provided on the base 25 of the first
generally channel shaped member 18, therebeing an aperture 44 provided in the base
31 to accommodate the main body of the spring 41. The spring 41 thus resiliently biases
the connecting member 30 downwardly.
[0015] If desired more than one spring or some other form of resilient biasing means may
be provided.
[0016] Two cams, only one of which is shown at 50 in Figure 1, are provided by tags pressed
out of the base 22 of the first generally channel shaped member 18 so as to extend
upwardly and outwardly of the first edge 13 of the panel 11. A corresponding tag 51
is pressed out of the base 31 of the connecting member 30 and the tag which provides
the cam 50 passes through the resultant aperture 52 formed thereby so that the under
surface of the tag 50 provides a cam for engagement with the upper surface of the
tag 51. If desired the tag 51 may be omitted and simply an appropriately shaped aperture
provided in the base 31 the lower edge of which would provide a cam follower for engagement
with the cam provided by the tag 50.
[0017] An aperture 53 is provided in the base 31 to permit access to be gained to the screws
20 hereinbefore described. A foot 55 is fixed to the bottom of the connecting member
30 so that the foot 55 projects below the bottom 56 of the first generally channel
shaped member 18 and hence below the bottom of the panel 11 so that a stepped configuration
is provided between the bottom of the connecting member 30 and the remainder of the
panel 11.
[0018] For convenience the structure at only the second edge 15 of the other panel 12 will
now be described; the first edge thereof being the same. The second mullion member
16 is formed with pairs of slots 60 similar to the slots 17 of the first mullion member
14 and a second generally channel shaped member 61 is attached to the second mullion
member 16 by means of hook portions 62 similar to the hook portions 19 and by a single
self-tapping securing screw 63 which passes through an aperture 64 in a base part
65 of the second channel member 61 and is threadedly received in an aperture 66 provided
in the second mullion member 16. Again a different number of pairs of hook portions
and securing screw may be provided.
[0019] The second generally channel shaped member 61 has spaced limbs 67 having out-turned
lips 68.
[0020] The second channel member 61 is provided with an acoustic foam material gasket 69
the spacing of the limbs 67 being such as to provide adequate space between the gasket
surfaces to receive the connecting channel 30.
[0021] The panels 11, 12 are supported at their bottoms on a floor track 70 and are located
at their upper edges 80 by a ceiling track 81 as best shown in Figures 2 and 3.
[0022] The floor track 70 comprises a base part 71 adapted to be secured to the floor in
any convenient manner and a panel engaging part 72 which is adjustable vertically
relative to the base part 71 by a screw jack means 73 so that any uneveness in the
floor can be accommodated.
[0023] The panel engaging part 72 has a channel shaped elongate socket 74 the base 75 of
which carries a high friction material such as a high density synthetic rubber strip
76 which is engaged by the apex 77 of a V-shaped tongue 78 provided on the under side
of the panels. The free edges of the limbs 79 of the socket 74 engage the sides of
the tongue. The frictional engagement between the tongue 78 and the strip 76 restrains
movement of the panels in a direction parallel to their central plane and hence restrains
the panels from separation in this direction.
[0024] Referring now to Figures 2 and 3 the ceiling track 81 is of generally inverted channel
shape having a base 82 connected to the ceiling in a desired manner and spaced side
limbs 83 the space between which is occupied by rockwool or other acoustic and/or
thermally insulating material. The side limbs 83 provided a tongue part 84 which is
received within a elongate groove or socket 85 having spaced limbs 87, provided in
a top member 86 of the panels. The relative lengths of the limbs 83 and 87 are such
as to permit of the tongue and socket parts 84, 85 being engaged whilst the tongue
78 can be lifted over a limb 79 of the floor track 70 and when the panel is lowered
to engage the tongue 78 with the strip 76.
[0025] In use, when it is desired to mount a panel, such as the panel 11, in juxtaposition
with another panel such as the panel 12 the panel 11 is first manipulated so that
the tongue part 84 is engaged between the limbs 87 of the socket 85 and with the panel
is positioned longitudinally closely adjacent the edges of the adjacent panels 12
and then the tongue 78 is lifted over a limb 79 of the track 70. The panel 11 is then
lowered and the feet 55 then engage the free ends of the limbs 79 before the remainder
of the panel engages the floor track 70.
[0026] Consequently, a resultant force exists between the locking members 30 at the first
and second edges of the panel 11 and the remainder of the panel, acting in a vertically
upward direction, and this causes each cam follower 51 to slid along the associated
cam 50 and thus cause the locking members 30 to move upwardly and outwardly away from
the associated first and second edges 13 of the one panel 11 and into engagement within
the limbs 67 of the second channel 61 of the adjacent panels 12. Consequently, the
panels 11 and 12 are connected together from movement transverse to the central plane
P of the panels. It will be appreciated that because the connecting members 30 only
move into engagement within the second channel members 61 over the last portion of
downward movement of the panel 11 the panel 11 can be offered up into position simply
by a transverse movement of the first panel 11 without requiring any longitudinal
movement of the panel 11 in the direction towards the panels 12.
[0027] When it is desired to dismount the panel 11 a reverse sequence of operations is performed.
[0028] The corners 90, 91 of the panels 11, 12 are, when the panels are connected together
as hereinbefore described spaced apart by a small distance sufficient to permit a
shelf or other mounting bracket 92 to pass therebetween. The bracket 92 comprises
a first limb 93 having a pair of hook formations 96 which are received in adjacent
slots 17. The limb 93 is connected by a curve part 94 to a second limb 95 which is
of a desired configuration, not shown, to support a shelf or any other desired component.
The brackets 92 are manipulated in position by initially aligning the limb 95 generally
parallel to the central plane P of the panel 11 and then passing the limb 93 through
the gap between the corners 90, 91. As the curved part 94 passes through the gap the
bracket is manipulated by rotating through 90° until it occupies the orientation shown
in Figure 1 and then the strip is moved downwardly to engage the hook formations 96
in the slots 17. Preferably guide surfaces are provided adjacent the slots 17 to guide
the hook formations 96 therein.
[0029] The bracket 92 may, instead, be positioned to extend from the opposite side of the
panels to that illustrated or could be engaged with the slots 60, with of course,
the orientations of the limbs 93 and 95 arranged correspondingly.
[0030] It will be appreciated that the out-turned lips 24 of the first channel member 18
are disposed in engagement with the coated out-turned lips 68 of the adjacent second
channel members 61 both to effect an acoustic and fire seal and also to position the
corners 90, 91 at the desired spacing.
[0031] The small gap necessary to accommodate the relatively thin bracket 92 may, in regions
where no bracket is provided, be trimmed with an appropriate trim strip is desired.
Where no facility for bracket provision is required then the length of the limbs of
the first and second channel members 18, 61 may be arranged so that the corners 90,
91 are in abutment.
[0032] In the present example the "solid" panel 12 comprises inner and outer skins 100,
101 made of 1 mm steel plate externally coated with plastics material. The skins 100,
101 receive therebetween the second mullion members 16 which are each a one-piece
member of generally channel shape the limbs 102 of the channel being received within
the skins 100, 101 and the skins 100, 101 having in-turned flanges 103 which overlie
inclined parts 104 of the base 105 of the mullion members 16. Rivets or screws are
provided between the overlaped parts of the skins and mullion members to secure them
together. Appropriate thermal and/or acoustic insulating material 106, such as rockwool
is provided between the skins 100 and 101.
[0033] The panel 11 shown in Figure 1 is a twin glazing unit. Such a twin glazing unit may,
if desired, have a venetian blind disposed between the glazing panels.
[0034] Such twin glazing units because of the presence of two sheets of glass are relatively
heavy and hence difficult to manipulate and, in addition, if made so as not to be
readily dismantable it is difficult or impossible to service any venetian blind or
the like disposed between the glass panes.
[0035] The twin glazing unit 11 comprises two sub-units 110, 111. Each sub-units 110, 111
comprises a sub-mullion members 112, 113 which combine together to form the first
mullion member 14 described hereinbefore. The sub-mullion members 112, 113 are separated
by an anti-vibration and acoustic damper material, for example, high density synthetic
rubber as indicated at 114. The sub-mullion units may be made of any suitable material
and have a recess 115, 116 which receive edge parts of respective glass panels 117,
118. A similar sub mullion assembly is provided at the opposite edge of the panel.
[0036] Bottom sub members 119 are also provided and combine together to provide the hereinbefore
described V-shaped tongue 78 at the bottom of the panel.
[0037] At the top, the sub-units have sub top members 120, 121 provided respectively with
recesses 122, 123 for the glass panels 117, 118 and have projecting flanges 124, 125
the free edges of which are forced into abutment with a thermal and/or acoustic insulating
material therebetween if desired by the hereinafter described means for securing the
sub-units together. The members 120, 121 provide the socket 85 which receives the
tongue part 84 of the ceiling track 81. A suitable sealing strip 126 is provided.
[0038] The sub-units 110, 111 are held together by virtue of engagement of the hooks 19
in the slots 17 of the sub-units and the screws 20 engaged in the apertures 23. The
part V-shaped tongues of the bottom sub member 119 also serve to urge the sub-units
110, 111 together. It will be appreciated, therefore, that it is relatively easy to
assemble the twin glazing unit on site by standing the sub-units 110, 111 on the track
and then securing them together with the generally channel shaped members 18, as described
above. Conversely the panels can be easily disassembled on site by reversing the procedure.
[0039] It is preferred that the mullion members, first and second generally channel shape
members and locking member are made by pressing in steel but may be made of other
material and/or other ways for example by rolling or moulding or extrusion in synthetic
plastics material.
[0040] It will be appreciated that the sub-units 110, 111 are isolated from acoustic vibration
from each other due to the presence of the anti-vibration damper strip 114.
[0041] Referring to Figure 4, when it is desired that the partition changes direction a
special junction panel is provided of the appropriate configuration. For example,
where the partition is to turn through a corner of 90° then a panel 12
a of the configuration shown in Figure 4
a is provided. The panel is of the same construction as the panel 12 described hereinbefore
except that instead of the inner and outer skins comprising planar parallel sheets
they each comprise L-shaped sheets. The edges 13
a, 15
a are each provided with a first generally channel shaped member and connecting member,
or second generally channel shaped member corresponding to the members 18 and 30 or
61 described with reference to Figure 1. The limbs of such a corner shaped panel may
be of equal length as shown in Figure 4
a or of different lengths as shown for example in Figure 4
b. It will be appreciated that the relative length of the limbs may be as desired.
[0042] Where the partition is to join a further partition, for example at a T-junction
then a T-shaped panel may be provided as shown at Figure 4
c the edges of the panels being provided with channel shaped members or channel members
and connecting members as necessary to interfit with adjacent panels. Figure 4
d shows the shape of panel which would be used where four partitions are to meet orthogonally
whilst Figure 4
e shows how three partitions may intersect, two at right angles and one at 120°. Any
other desired configuration may be provided and would, of course, be provided with
appropriate generally channel shape or generally channel shaped and connecting members.
By providing such panels of specific configuration it is arranged that the connection
between all panels of a partition is identifical and thus a constant standard of connection
is achieved throughout the partition with no exception at corners or other junctions.
There is therefore no interruption of the integrity of the partitioning in the vicinity
of a corner or other junction.
[0043] Various modifications may be made without departing from the scope of the invention.
For example, a modified connecting means between for example, two solid panels is
shown in Figure 5. Similar parts to those shown in Figures 1 to 3 are indicated by
the same reference numerals but the prime sign added.
[0044] In this arrangement, two solid panels are indicated at 12ʹ and 12
a. Panel 12ʹ is substantially the same as panel 12 of Figure 1 whilst the portion of
panel 12
a as seen in Figure 5 is the same as the unseen portion of the panel 12 in Figure 1.
[0045] A first channel shaped member 18ʹ is provided but this does not have hooks such as
shown at 19 in Figure 1, to engage in slots 17ʹ, but is secured to the mullion 14ʹ
of panel 12
a simply by screws 20ʹ spaced along the edge 13ʹ of the panel 12
a. If the panel 12
a were a glazed panel similar to panel 11 of Figure 1, the screws 20ʹ would need to
be offset in order that the member 18ʹ will be connected to both sub-units of glazed
panel 11.
[0046] Similarly a second channel shaped channel member 61ʹ of the Figure 5 version does
not have hooks to engage in slots 60ʹ of panel 12ʹ but again is simply secured by
spaced screws 63ʹ. The spring 41 is omitted in the Figure 5 arrangement but a clip
35ʹ is provided to bias a connecting member 30ʹ to the first member 18ʹ.
[0047] In place of two cams 50,51 as in Figure 1, a moulded block B is secured to the mullion
14ʹ of the panel 12
a and has an inclined surface S which engages with a tag 50ʹ which may be provided
by member 18ʹ which is itself engaged by a lower edge 51ʹ of an opening 52ʹ of the
connecting member 30ʹ as the connecting member 30ʹ moves upwardly, so that the connecting
member 30ʹ is constrained to move outwardly and upwardly relative to the edge 13ʹ
of panel 12
a when panel 12
a is moved into juxtaposition with channel 12ʹ.
[0048] Thus the slots 60ʹ and 17ʹ of the first and second channel shaped members 18ʹ and
61ʹ in the Figure 5 arrangement, are only used to be engaged by brackets 92ʹ.
[0049] In all other respects, the connecting means of Figure 5 operates as described with
reference to the Figures 1 to 3 arrangements.
