Abstract

A pair of mutually engageable structural panels A, B have opposed longitudinal edges provided with interlocking head and socket portions. In one embodiment (Fig. 1) the head portion 9 has a groove 13 at one side in which a rib 7 of the socket portion 5 is engaged to provide a pivot about which the head is rotated into the socket portion. The opposite edge 6 of the socket portion 5 preferably travels smoothly over the head as the panels are engaged and disengaged. In another embodiment (Fig. 4) the head portion 23 is joined to the panel by a neck portion which is off set from the mid plane of the panel and a curved slot 26 is defined between the head portion 23 and an adjacent surface of the panel to receive an edge of the socket portion 20. In this embodiment the angular relationship of the panels can be adjusted whilst maintaining the engagement. Numerous building uses are specified together with the use of the Fig. 4 construction as a roller shutter. <IMAGE>

Description

SPECIFICATION Mutually engageable panels The aim ofthis invention isto provide an arrangement whereby two or more structural panels of elongate form, perhaps as long as 3 metres or more, can be quickly and simply engaged and, once engaged, are capable of being readily handled as a combined unit.

This invention provides a pair of mutually engageable elongate panels in which longitudinal edges of the panels are provided with complementary mutually engageable locking portions, the arrangement being such that the locking portions are mutually engageable by bringing the panels together in edge-to-edge relation and, when engaged, offer positive resistance to separation in the plane of the panels.

The panels can thus be mutually engaged without the use of separate clips orfastenings and even panels of considerable length can be connected without the need forsliding them in longitudinally as with panels used in compost bins for example. The panels are therefore quick and easy to assemble even in long lengths. Tolerances are also less critical thanforslide in engagement. Even so,the panels can readily be handled as a combined unit.

Ideally the locking portions are disposed wholly within the thickness of the respective panel since this makesthem less susceptible to damage. which could lead to difficulty in engagement.

It is also extremely desirable (though not essential) thatthe panels should be of hollow section to increasetheirstrength to weight ratio.

The locking portions preferably comprise complementary head and socket portions.

It is much preferred that the locking portions should be capable of being engaged by bringing them together and then angularly rotating one panel relative to the other. This form of engagement greatly reduces the risk of separation during handling compared with a simple linear engagement.

In one particularly preferred arrangement the head portion is joined to the panel by a neck portion which comprises a groove and the socket portion carries a locking rib for positive location in the groove such that the rib cannot ride out of the groove over the head portion when the locking portions are mutually engaged, and the arrangement is such that the rib and groove together form a pivot about which the head portion is angularly rotatable into the socket portion. Although ribs and grooves may be provided on opposite sides of the head portion, preferablythe configuration ofthe locking portions are such that the opposite part of the socket portion to thatwhich carries the locking rib rides smoothly over the head and neck portions during insertion and removal of the head portion from the socket portion.

In another much preferred arrangement the head portion is joined to a neck portion which is offset to one side ofthe mid plane of the panel and a curved slot is defined between the head portion and an opposed surface of the respective panel for reception of part of the socket portion therein.The head portion is preferably rotatable within the socket portion so that the angular relationship ofthe panels can be adjusted.

The invention will now be exemplified with reference to the accompanying drawings, in which: Figure lisa transverse section through a pair of panels in accordance with the invention, Figures2 to 4 are similar sections through further pairs of panels in accordance with the invention, Figure5is a transverse section through a corner joint between a pair of panels as shown in Figure 1, Figure 6 is a transverse section through a Tjoint between two panels of Figure 1, Figure 7is a vertical section through the foot portion of a panel of Figure 1, Figure8is a vertical section throughthe strengthening bar of a panel of Figure 1,and Figure 9 is a side view of a security wall constructed using the panels.

Figure 1 shows a pair of elongate plank-like panels Aand B, which mayforexample be aluminium or plastics extrusions of uniform section. Each panel comprises a pair of spaced parallel walls 1,2which are optionally joined by webs 3. Along one edge of panel Ate walls 1 and 2 are joined by a concave connecting wall4formingasocket portion Sof curved internal shape. At its junction with wall 1 the socket portion terminates in an inwardly directed edge 6 whereas the opposite edge is provided with an inwardly directed locking rib 7 of rectangular section, the edge 6 and rib 7 togetherdefining between them an opening 8.

Atthe adjacent edge of panel Bwalls 1 and 2 are joined to a head portion 9 containing a circular aperture 10. The outer surface of wall 1 curves inwardly at 11 to meetthe head portion 9thus forming a shallow V-shaped notch 12. The external shape of head portion 9 is complementaryto the internal shape of socket portion 5. At its junction with wall 2the head portion 9 is provided with a locking groove 13 of rectangular section to receive the locking rib 7. Notch 12 and groove l3togetherform a neck portion which is narrower than the head portion 9.

In use, the panels are interengaged by inserting the locking rib 7 into the groove 13 with thewalls 2 angularly inclined towards each other. The panels are then angularly rotated about the pivot formed by rib 7 and groove 13 so that the head portion 9 snaps into the socket portion 5, edge 6 riding smoothly into notch 12, and bringing the panels to a co-planar position as shown in Figure 1. When thus engaged the panes are securely held together in the plane of the panels by virtue of the fact that the head portion is of greaterwidth than the opening 8 and, even more importantly, because rib 7 is positively located in groove 13. The panels can however easily be disengaged by relative rotation in groove 13.The panels can however easily be disengaged by relative rotation in the opposite direction about rib 7so that the edge 6 rides smoothly up over head portion 9.

Since the head and socket portions 9,5 are disposed wholly within the thickness ofthe respective panels they are notsusceptibleto damage during handling and the engaged panels provide a smooth external profile.

Figure 2 shows a similar arrangement in which parts which generally correspond to those of Figure 1 have the same reference characters. The main differences are thatthe panels contain a single cavity 15 which extends into the head portion 9. the complementary locking rib 7 and groove 13 are of rounded outline to give a smoother pivot action whilst maintaining a positive locking action.

Similarly, notch 12 and edge 6 a re aiso more rounded, although they operate in precisely the same way.

Figure3showsanothersimilararrangementbutin this casethe panels have been rolledfrom aflat metal strip. Parts which generally correspond to those of Figures 1 and 2 again havethesame reference characters. Rib 7 is now formed by rolling back one edge of the strip internally into a C-shape, groove 13 being provided with a locking shoulder 1 3a which is engaged bythe extreme edge ofthe strip. The opposite edge 6 of the socket portion is formed by internally rolling back the opposite edge portion ofthe strip. The socket portion is thus formed by the internal cavity 15 ofthe panel.

Figure 4 shows a similar pair of panels A and B provided with different head and socket portions. In panel Ate walls 1 and 2 are inturned to join a part-cylindrical socket portion 20 which has an opening 21 adjacent to thejunction with wall 2.

Opening 21 is narrower than the internal diameter of the socket portion 20. In panel B wall 2 is joined by an inwardly inclined neck portion 22 to a cylindrical head portion 23 containing an aperture 24. The head portion lies substantially on the mid plane ofthe panel.Acurved connecting wall 25 joinswalls 1 and 2 inwardly of head portion 23 to form a curved slot 26 between wall 25 and the head portion. Again the head and socket portions are disposed within the external thickness of the side walls 1,2.

In use, the head portion 23 is inserted into the socket portion 20 through the opening 21 with the walls 2 inclined toward each other, and the panels are angularly rotated so that the wall ofthe socket portion 20 advances into the slot 26 securely locking the two panels together. The panels can be freely rotated into the planar configuration shown, but they could also be used in an angularly inclined position.

The overlapping surfaces of socket portion 20, head portion 23 and connecting wall 25 could be provided with complementary longitudinal ribs to provide positive angular location of one panel relative to the other.

In each of the embodiments described above the opposite longitudinal edges of each panel are provided with complementary head and socket portions ofthe kind described so that a number of panels can be secured together. Alternatively, panels with two head portions and panels with two socket portions could be used alternately. The panels of Figure 4 could also be used to form a roller shutter with rods inserted through the apertures 24, the projecting ends ofthe rods being located in guide channels.

Figure 5 shows how a corner section C having a head portion 9' and a mutually perpendicular socket portion 5' can be used to join two ofthe panels of Figure 1.

Figure 6shows a Tsection Dfor use in joining threepanelsA,B1 and B2 in a T configuration. The two arms of the T-section have complementary head and socket portions 9" and 5" and the stem has a socket portion 5"' as shown, or another head portion.

The panels of Figure 4 could of course be used in the arrangements of Figures 5 and 6.

Figure 7 shows how the lower edge of a wall formed of interlocking panels A can be supported by an L-shaped foot section 30. The lower limb 31 ofthe foot section is secured to a floor by screws 32 and the upright limb 33 is secured to the outside face ofthe wall by screws 34. Skirting 35 can then be screwed to the inside face by screws 36.

Figure 8 shows a horizontal H section strengthening bar 40 into which upper and lower wall sections A1,A2 are slotted and secured by screws 41.

For security purposes metal panels can be used, or alternate metal and plastics panels. Also, as shown in Figure 9, upright tubes 50 threaded internally at each end can be inserted through the apertures 10 or 24 of the head portions and secured by bolts 51 to steel top and bottom rails 52, to form a rigid steel frame. Externally threaded rods and securing nuts could also be used.

The enclosed spaces between the walls 1 and 2 provide the panels with good heat insulating properties and make them relatively lightweight and cheap to manufacture. They also provide wiring or service pipe compartments. Double walls could also be used for additional heat insulation, preferably with a heat insulating layerbetweentheinnerand outer panels.

The panes have numerous uses including partition walls, garages, lean-tos, sheds, dog kennels, flooring, shelving, boxes and fences. Door and window openings can easily be incorporated in the structure and the panels can be used to support various fixtures and fittings. Open fencing can be constructed using posts formed of the panels separated by cross bars formed of short lengths of panel. The panels of Figure 4 are of advantagewhere curved walls are required.

Theabilityto engage the panels in edge-to-edge relation without having to slide them longitudinally isa great advantage notonlyfromthe handling point of view but also because of the increased speed of assembly.
