Description
The present invention relates to a partition system, in particular
to a demountable, battenless partition system.
Many known demountable partition systems have a plurality of
adjacent panels whose joints are covered with removable strips or
battens. Such strips or battens may actually secure the panels in
place, or merely provide a means for hiding the panel attachment
system, which latter for example might be self-tapping screws. The
design of partition systems, of aesthetically acceptable
appearance, without such battens which are also readily
demountable, presents certain difficulties, and it is the object of
the present invention to provide such a battenless partition system
in which individual panels are readily demountable.
According to the present invention there is provided a partition
system having a plurality of panels, each panel being provided with
a plurality of clips for attaching the panels to a framework of
supporting members, the clips being received in corresponding slots
in the supporting members whereby individual panels are readily
demountable therefrom.
Conveniently the panels of a partition system can be provided with
a clip which is resilient and is generally hook-shaped, the clip
having a lead in portion for facilitating engagement with the
respective supporting member, a clipping portion for releasably
securing the clip to the supporting member and a tail portion for
attaching the clip to a panel and means for locating the clip
thereto in a predetermined position.
According to another aspect of the present invention there is
provided a resilient, generally hook-shaped clip having a clipping
portion for releasably securing the clip to a supporting member, a
lead in portion for facilitating engagement with the supporting
member and tail portions, each tail end of the clip being formed
with a pointed barb and a respective notch being formed in the
edges of the clip adjacent to each tail end thereof.
Advantageously clips are manufactured from thin metal strip and are
attached to the panel before the panels are mounted on the support
members. It is to be understood however that other materials such
as plastics may be used for the clips.
Conveniently the supporting stud members are of I, H, J, Z or C
section and may be formed from aluminum, steel, rigid plastics or
like materials. Furthermore, the stud members can be of hollow
rectangular cross section. However, any configuration which
provides a flange for slotting in the plane of the panels, or which
may be adapted by additional components to provide such a flange
for slotting may be adopted. Alternatively, extruded sections can
be used such as tubing with slots formed therealong for receiving
the clips. Similarly the panels utilised may be of any conventional
building panel material or composite thereof.
The invention will be described further, by way of example, with
reference to the accompanying drawings, in which:
FIG. 1 is an exploded perspective view of a portion of the
partition system, according to a first embodiment of the present
invention,
FIG. 2 is one form of assembly for the partition system of FIG.
1,
FIG. 3A is a section through a clip for use with the system of FIG.
6 according to a second embodiment of the present invention,
FIG. 3B is a perspective view of the clip of FIG. 6,
FIGS. 4a, 4b and 4c are sequential perspective views showing the
mounting process of the clip of FIG. 3 to the panels,
FIG. 5 is a section illustrating the mounting of the panels to the
supporting members, using the clip of FIG. 3, and
FIG. 6 is a perspective view of a portion of the partition system
according to the second embodiment of the invention.
Referring to FIG. 1 an I section stud member has a pair of punched
rectangular slots 2 in each of its end flanges 1, the slots 2 in
each flange being positioned adjacent one another on opposite sides
of the stud web. The material of the stud can be punched out
completely or bent back as shown in FIG. 1. The stud serves as an
interconnecting support member between a pair of panels 5, the
panels in the preferred embodiment having a gypsum plaster core
with a paper covering and may be prefinished with a vinyl or
similar plastic. If the material of the stud is bent back the
removal of the panel away from the stud is facilitated during
demounting in that clips 28 (FIG. 6) engage the bent material which
forces the panel in a direction away from the slots 2. In the
preferred embodiment a flat metallic or plastics strip 4 is bonded
down both longitudinal edge regions on the unexposed face of panel
5 by for example a suitable adhesive. The strip 4 may be folded
back on itself as shown at 7, so as to provide an over-lapped
region to provide a more secure fixing for self-tapping screws. The
clips 3 have a lead in portion L to facilitate their engagement
with the stud 1, a clipping portion C and a tail T. The clip may
have square 3b or barbed 3a tail ends which serve as to locate the
clips in respective punched slots 6. The clips 3 are locked into
position on the strip 7 by insertion of the tail end of each clip
into the respective rectangular punched slot 6 formed in the strip
4 and then by insertion of a self-tapping screw or a blind rivet or
other fixing means through the punched guide holes 8 in clip 3 and
strip 4. The clips are positioned to match the slots in the
studs.
It is also to be understood that where the panel material supplies
a ready fixing for rivets, screws or other fixing, as for example
when a timber or particle board panel is used, then no edge strips
are required.
A second embodiment of the clip 28 (FIG. 3) has a lead in portion L
and a clipping portion C similar to the clip 3 (FIG. 1).
The preferred clip 28 (FIG. 3) is generally hook-shaped and has
good spring retention properties and is fixed to the panel without
secondary fixings. Each end of the clip 28 has pointed barbs 40,
FIG. 5 which penetrate into the panel and notches 30 engage the
curved slots 32 (FIG. 4) punched in the bonded strip thus leading
to a more effective grip when the weight of the panel is borne. The
slots 32 can be of any suitably tapered configuration.
In order to fix the clips 28 panels cut to a preferred length are
placed face downwards with the bonded strips uppermost FIG. 4. In
the untensioned position one end of the clip protrudes slightly
further than the other end FIG. 4a. The clip is fixed by inserting
the protruding end through the top slot of the pair of slots in the
bonded strip and sliding the end between the strip and the face of
the panel (FIG. 4b). The other end is then extended to pass through
the second of the paired slots in the strip and slides between the
strip and panel (FIG. 4c).
The clip 28 is self locking on notches 30 cut just above each end
which fit over the strip. The clip 28 has an improved locking
action since when a panel is mounted in position the locking action
is increased as the clip supports the weight of the panel on the
stud. In addition the top of the clip is shaped to assist
demounting by automatically forcing the board away from the stud as
it is lifted.
The system shown in FIG. 6 uses the second clip as shown in FIG. 3.
The system comprises panels such as plasterboard with a metallic or
plastics strip 24 bonded down both edge regions on the unexposed
face of the board. In the preferred embodiment the strips are
perforated at intervals down the length with paired slots 32 (see
FIG. 4a) to receive the clip 28 shown in FIG. 3. Clips 28 are
spaced along the metal strips 24 (FIG. 6) to correspond with the
slots 2 cut in the flange of the I, section studs. The panels are
fitted by passing the clips 28 through the studding slots 2 and
locking into position by lowering the board until its weight is
taken on the clip in the same way as for the first clips 3, the
clips 28 automatically gripping the studs. This system does not
require special tools to fix the clips 28. To demount the board it
is raised to clear the hook section of the clip from the bottom of
the slot in the stud and then drawn outwards and removed.
If wide panels are used, then a centre stud may be used to give
support down the panel centre and a further metal strip or short
length of strip can be applied to the centre of the panel to
provide attachment. Alternatively adhesive or a double sided self
adhesive tape can be used to provide attachment to the centre stud.
Three metallic or plastic strips 24 are bonded to the unexposed
surface of the board, one strip down either edge region and one
down the centre. Once the clips are in position the panel is
lowered onto three support studs. In this case the centre stud will
have one slot cut into the flange of for example a C section stud.
Alternatively one side of an I section stud could be used.
The floor and ceiling supports may comprise typical channel tracks
14 (FIG. 2), conventionally used in the art, the top and bottom
tracks 14 as shown in FIG. 2 being interconnected by H section
studs 16. The rectangular slots 2 in the studs 16 are preferably
greater in horizontal dimension than the clips which engage them.
This enables the assembly to accommodate differences in width of
panels on alternate faces of the partition, which arise from panel
manufacturing tolerances, without deformation or strain in the
component parts, consequent in previous systems of this type. In
erection the ceiling support is fixed and the studs 16 raised into
engagement with it by a shim or wedge 22 in such a manner that the
slots in all the studs remain level. The panels with clips attached
are raised using, for instance, a conventional foot lifter, the
clips are then engaged in the slots in the studs and the panel
allowed to fall so that the clips engage and clamp the panel to the
studs. Either the studs may be all erected first and the panels
applied or studs and panels can be erected alternately. To complete
the partition suitable conventional components can be used such as
trims 20 applied at the ceiling, and conventional applied skirtings
or "bases" including recessed skirtings, can be used. FIG. 2, by
way of example, shows a clip 10 with an extruded skirting 12
clipped on.
Apart from preventing vibration the gripping action of both type of
clips allows a vertical tolerance for positioning the stud in
relation to the panel. Furthermore, when erecting, successive
panels can be pushed towards the fixed end of the partition with
the clips sliding along the bottom edge of the slot in the stud to
ensure a tight joint between the panels.
