[0001] This invention relates to panel edge strips to facilitate the edge-to-edge joining
of panels and/or the attachment of accessories to panels. The invention has particular
but by no means exclusive application to panels, for example desk top panels, in modular
furniture systems.
[0002] Traditionally, accessories have been attached to the surface ends of furniture by
means of clamps, or by direct fastening to the surface, for example through use of
nails, or screws or other devices. These forms of attachment are semi-permanent and
do not afford the flexibility of being able to readily move accessories from one surface
edge position to another. If nails or screws are used, the surface top is left unsightly
when, at a later time, the position of an accessory is altered.
[0003] Known panels used in modular wall and partition systems have elongate edge pieces
attached to planar end surfaces of each panel. These edge pieces have a single slot
for interengaging consecutive panels. In other systems, the slot may integrally be
formed in the panel end surface.
[0004] It is an object of the invention to provide an improved edge strip for a panel which
is adaptable to facilitate the edge-to-edge joining of panels and/or the attachment
of accessories, especially in modular furniture systems.
[0005] The invention accordingly provides, an edge strip for a panel, comprising an elongate
front portion and respective flange portions disposed at the sides of the elongate
front portion whereby the edge strip is of generally U-shaped configuration, wherein
the said front portion and at least one of said flange portions each have an undercut
groove extending longitudinally of the edge strip and dimensioned to snugly receive
longitudinal inserts adapted to engage and secure together registered grooves on adjacent
edge strips.
[0006] The front portion of the edge strip preferably has two undercut grooves. These grooves
are advantageously of rectangular cross-section, and one or more of the grooves, for
example the groove in the flange portion, may conveniently have a channel in its floor
to seat fasteners for attaching the edge strip to a panel.
[0007] The invention also extends to a panel having at least one edge or edge face fitted
with an edge strip as aforedescribed.
[0008] The panel may include a further edge or edge face fitted with an elongate strip having
respective longitudinal side edges, which strip has a plurality of spaced transversely
extending slots or holes opening at one or other of said side edges for receiving
complementary studs.
[0009] The invention will now be further described, by way of example, with reference to
the accompanying drawings, in which:-

of the invention;

strips, of the form shown in Figures 1 and 2, to join panels together at different
relative angular positions;

invention, and also with slotted strips for enhanced versatility.
[0010] The panel edge strip 10 illustrated in Figures 1 and 2 comprises an integral metal
extrusion formed with an elongate front portion 12 and respective flange portions
14, 16 (hereinafter referred to as flanges) disposed at the sides of the front portion
12 whereby the edge strip is of generally U-shaped configuration. Front portion 12
and flanges 14, 16 each have an undercut groove 18, 20, 22 which extends longitudinally
of the edge strip. The grooves are of substantially similar rectangular cross-section
with openings 19 defined by opposed inwardly overhanging lips 21, 23. There are actually
two grooves 18a, 18b side-by-side in front portion 12 separated by a T-section rib
24. The whole edge strip is symmetrical about a plane containing the web segment 25
of rib 24, and grooves 20, 22 extend to adjacent the free edge face 15 of flanges
14,16.
[0011] Flanges 14, 16 are integrally connected to front portion 12 by respective curved
corner webs 26, 27.
[0012] Each of the grooves 20, 22 in flanges 14, 16 has a rectangular section channel 28
in its floor to seat fasteners for attaching the edge strip to a panel. Channels 28
are slightly wider than but in register with the opening 19. A C-section rib 32 is
provided internally behind rib 24 for a purpose to be described.
[0013] Flanges 14, 16 may be 5 to 80mm wide (most conveniently about 25mm), while openings
19 may be 1-60mm wide (most conveniently about 7mm). Lips 21, 23 may overhang by 1-15mm,
say about 4mm. Front portion 12 may be 5 to 150mm wide, for example about 55mm wide.
[0014] Figure 2 depicts the manner in which the edge strip 10 may be secured to an edge
face of a panel 50. The panel is rebated at both faces 34, 35 to accommodate flanges
14, 16 and position the external faces of the flanges 14a, 16a substantially flush
with the panel faces. Fasteners, such as the screws ilustrated, are driven through
from channels 28 so that their heads are seated in the channels.
[0015] The manner in which edge strips of the forms shown in Figures 1 and 2 may be coupled
together is illustrated in Figures 3A-3C and 4. In essence, undercut grooves 18, 20,
22 are similarly dimensioned to snugly and firmly receive longitudinal inserts 40
of similar uniform cross-section adapted to engage and secure together respective
registering grooves on adjacent edge strips. In the case of Figure 3A, two panels
50, 50' are fitted with strips edge 10, 10' and are butt joined to a pair of H-section
inserts 40a, 40b passed along grooves 18a, 18b in the front portions 12, 12' of the
panel edge strips 10, 10'. Figure 3B depicts a 90° join, while Figure 3C illustrates
a mutual angular fixing using a V-shaped coupling insert 41. Inserts 40, 41 are typically
extruded in a suitable plastics material e.g. Polyvinyl chloride (PVC).
[0016] Figure 4 shows two partition panels in position to be butt-joined, with the inserts
40a, 40b ready to be slid down the opposed grooves. The panels include cable ducts
51 at their lower ends.
[0017] The versatility of edge strip 10 is highlighted in Figure 5. An accessory base 60
is fastened to the strip by engagement of a screw 62 through the base 60 into a metal
insert 62 slidably carried by groove 20. The position of the accessory can be varied
along the groove by loosening the screw and moving the insert along the groove.
[0018] Edge strips 12 may be closed at their ends by end caps 70 of the configuration depicted
in Figure 6. The end cap 70 engages the edge strip by way of a pair of projecting
hollow spigots 72 which are a close matching fit in the cavitites 74 under corner
webs 26, 27 (Figure 1) between the adjacent side walls of grooves 20, 22. The external
surfaces of the cap are designed to be flush with the corresponding surfaces of the
edge strip. The end cap 70 may be secured into the end of the edge strip 12 by a fastener,
for example a screw, which engages with C-section rib 32.
[0019] Figure 7 depicts an especially versatile panel 50" fitted at two edge faces 50a with
edge strips 10" and at the other two edge faces 50b with slotted strips 80. Opening
at the lower longitudinal side edge 81 of strip 80 are a plurality of, in this case
four, equi-spaced transversely extending slots 82. These slots are dimensioned to
receive respective studs of another furniture component and extend about half way
across the strip. In this manner panel 50" may be supported by the furniture component
bearing the studs. It will be noted that edge faces 50b are formed with sockets or
notches 50c behind and in register with slots 82" to seat the heads of the studs.
[0020] Each slot 82 has a margin which is inclined with respect to the adjacent face of
the strip so that the slot is correspondingly inclined. A suitable matching stud has
an enlarged slotted head, a threaded shank, and an intermediate unthreaded portion
which abuts the surface in which the stud is threaded and is complementary to the
slots. This intermediate stud portion is of slightly less width than each slot and
the inner end of each slot is curved to match the circumference of the intermediate
stud portion.
