Definitions
- a method of joining stiff plate profile members into broad lamellae or panels and a lamella or panel element or product produced by that method is a method of joining stiff plate profile members into broad lamellae or panels and a lamella or panel element or product produced by that method.
- the present invention relates to a method of join ⁇ ing hollow, extruded profiled plate lengths for the formation of broad lamellae or panels, e.g. broad lamel ⁇ la constructions for sun shading systems.
- the long profile elements will have to be reasonably stiff, and even though they are produced with all care they will, however, inevitab ⁇ ly come up with such minor wrynesses over the long length which may not be visible at all, but in connec- tion with the stiffness of the elements make it almost impossible to use the said joining by a pushing together of the elements.
- the engagement portions could well be shaped with suitable tolerances, but the result would be that a few.elements could be joined in an easy manner for obtaining a fixed joining, while the joinings be ⁇ tween many other elements would not be fixed, which is entirely unacceptable; in many other cases an already initiated pushing-together joining would have to be stopped, e.g. upon three fourths of the joining movement having been carried out. Possibly many of the latter joinings could be accomplished anyway by an extra strong pressing together, but for one part this will require a quite costly pressing equipment, and for another part there would be considerable risks of skewnesses occur ⁇ ring in the joined structure.
- profile elements the edge portions of which are shaped with interfacing engagement profile portions, which at each edge portion are provided on flange means projecting inwardly from the opposed other sides of the profile element with a free distance between the opposed engage ⁇ ment profile portions, these portions being shaped such that by a laying together of the profile elements edge to edge they will interlock these elements in the trans ⁇ verse direction;
- the engagement profile portions are provided on flange means, which have a widening inside the profile element, such that in their laid together condition they will show a bilaterally widened head portion, these head portions thus being located opposite to each other with a free space therebetween;
- an extra profile member shaped as a narrow plate strip, the opposed edges of which are provided with part-cylindrical flange por ⁇ tions of such cross sectional shapes that these flange portions, by an insertion of the extra profile member along the laid together engagement profile portions, can engage over the widened head portions so as to hold these together.
- the extra joining profile member is not a thick block string, but a plate strip with part-cylindrical widenings along the outer edges, because this will be decisive for this profile member being to some degree flexible, such that when it is inserted it may adapt itself to a slightly curved run of the laid together edge portions of the plate profile elements, should such a run occur.
- the outwardly open part-cylindrical flange portions of the joining profile member may well be designed with a certain oversize relative to the flange head portions which they shall surround. For a joint over a short length this will result in an undesired loose joint, but when the joint is pronounced elongated and shows even the slightest deviations from an accurately linear shape, then the said part-cylindrical flange portions will at least at places hold the edges of plate profile elements tightly joined, whereby these elements as re ⁇ spective wholes will engage each other in an entirely stable manner.
- Fig. 1 is a perspective view of a few lamellae in a sun shading system
- Fig. 2 is a sectional view of some adjoining pro ⁇ file elements for forming such lamellae
- Fig. 3 is a perspective view thereof.
- Fig. 4 is a perspective view of a lamella when being assembled
- Fig. 5 is a sectional view of a panel element ac ⁇ cording to the invention.
- Figs. 6 and 7 are perspective views of structures provided in accordance with the invention.
- Fig. 1 is shown the upper ends of a few laminae 2 which are mounted in a rotatable manner between an upper supporting beam 4 and a corresponding lower beam or box, in which means may be provided for concurrent turning of all the laminae for changing the angular positions thereof, as it can be desirable in a sun shad ⁇ ing system.
- What is here concerned is heavy, large lami ⁇ nae with a width of e.g. 40-80 cm and with a length of some 2-8 meters.
- these elements should be able to resist quite heavy wind forces and even other influences they should be designed so as to be very stiff, and moreover they should be as light as possible.
- their outer surfaces should be smooth. It could be close to hand to think of the elements as extruded aluminium profiles, but when their width is more than some 30 cm this is not an attractive possibility, while it is al ⁇ most a practical impossibility if the width is 60 cm or more.
- Fig. 2 is shown an example of such profiles, which are ready to be joined edge to edge.
- a V-profile 6 which at each of its opposed free edges of the side walls desig ⁇ nated 8 is shaped with flanges 10 and 12 projecting inwardly towards each other.
- the flange 10 is shaped with a cross sectionally half-cir ⁇ cular portion 14 having a groove 16 opening towards the right and an opposed outer side 18 of a part-circular configuration concentric with the groove 16.
- the other flange 12 has a quite similar part-circu ⁇ lar widening, here designated 18', while at its front side it has forwardly projecting widening 20 with a half-cylindrical cross section corresponding to the shape of the groove 16.
- the V-profile is provided with a cross wall 22 hav ⁇ ing a projecting middle rib 24 shaped with a channel portion 26. Due to the cross wall 22 the profile element 6 will be a stiff hollow profile element.
- This profile is of a trapezoidal shape, with the outer walls 8 and with cross walls 22. At its left hand end it is shaped exactly as a counterpart to the edge area of the profile 6, i.e. with the flange portion 12,18',20 located next to the groove flange 14,16 of the profile 6 and with its own groove flange 14,16 located next to the flange 12,20 of the profile 6. At its opposite, right hand end the profile 28 is shaped in a manner corresponding to the profile 6, though in the example shown with a somewhat smaller distance between the opposed flange portions 14,16 and 18',20.
- a further profile 30 which is shaped fully similarly to the pro ⁇ file, only with a smaller width at its open edge, cor ⁇ responding to the reduced edge width of the right hand end of the profile 28.
- the profile 30 is oriented such that the profile details 10-20 are located in a manner quite similar to their location at the left hand edge of the profile 28.
- the profiles 28 and 30 are shown entirely laid together, with the rib portions 20 received in the grooves 16 by a purely transversely oriented pushing to ⁇ gether of the profiles. Thereby the profiles will engage each other lockingly in the transverse direction perpen ⁇ dicular to the pushing together direction.
- the radius of the ribs 20 is slightly smaller than the radius of the groove depressions 16, such that the relevant, respec ⁇ tive engagements can be established along the entire length of the profiles, also when the lengthwise direc ⁇ tion of the edge portions is not linear in any absolute sense.
- the laid together profile details 10-20 will appear as inwardly protruding ribs 32 having circular-cylindrical widenings or heads 34 formed by the surface portions 18 and 18' on the flanges to be joined.
- the profile member 36 comprises an intermediate plate strip portion 38, the opposed longitudinal edges of which are provided with outwardly open, part-cylindrical flanges 40, which are adapted to surround the head portions 34, such that by the insertion of the locking profile 36 the laid to ⁇ gether, head forming parts will be totally interlocked by their local engagement with the closely surrounding profile portions 40.
- Fig. 4 it is illustrated how the joining profile members 36 are inserted along the entire length of the edgewise joined plate profile elements 6, 28 and 30, and it should be noticed that the lengths in question may be e.g. 2-8 meters, i.e. relatively high lengths.
- the ends of the joined profile elements may be covered by an end plate 44, in which holes 46 are provided for receiving bolts to be screwed into the ends of the hollow flange portions 24,26 on the cross walls 22 of the profiled elements, and if the use of pivot pins is desired such pins may be connected with these end plates.
- the invention is not limited to the production of sun shading lamellae, as it may be applied generally wherever it is desired to join relatively narrow profile elements into broader lamella or panel structures. It will be appreciated that based on the profile elements shown in Fig. 2 it is possible to build up other lamella configurations, e.g. relatively narrow profiles by join ⁇ ing two elements 30 directly edge to edge or with use of two intermediate profiles 28, which are interconnected at their broad ends and are furthermore joined with end profiles 30 at both ends or edges.
- the joining profile portions 40 should not neces ⁇ sarily extend over more than 180°, as their primary function is to merely hold the head forming portions 34 together, against each other in the width direction of the assembled structure, while the holding together in the cross direction will be effected by the cross wall portions 22 of the profile elements.
- An example of this is shown in Fig. 5, where a connector profile 54 having U-shaped edge flanges 56 cooperates with inwardly pro ⁇ truding plate flanges 58 next to the edges of the pro ⁇ file elements, which are otherwise joined by an ordinary socket joint.
- this joint At the right hand side of this joint another joint is shown, where the flanges 58' are mu ⁇ tually spaced, but held together by means of a corre ⁇ spondingly broader joining head 56' on the joining pro ⁇ file 54'; such a broad joining head, however, is not particularly advantageous, as it causes an increased stiffness of the joining profile, whereby the latter can less easily adapt itself to the slightly curved shape of the profile elements, whereby it may be more difficult to insert.
- a joining profile may extend in the plane of the profile elements and serve to hold together such portions 62, which are pro ⁇ jections on the edge walls 64 of the profile elements, whereby the outer edge areas will be held together at interengaging flange portions 66.
- a joining profile may extend in the plane of the profile elements and serve to hold together such portions 62, which are pro ⁇ jections on the edge walls 64 of the profile elements, whereby the outer edge areas will be held together at interengaging flange portions 66.
- the profile elements at one side do not have any edge recess, but are terminated by an end wall 68, along the edges of which there are provided engagement ribs 70 for guidingly receiving the side edges of the neighbouring element.
- the edge wall 68 is at one or more places provided with a projecting T-profiled portion 72, which is held together with a corresponding profile portion 74 on the neighbouring element by means of joining profiles 76.
- the elements can be surface treated before the joining, whereby no aftertreatment will be needed.

Abstract
Dans des systèmes de pare-soleil de grande dimension notamment, il est possible que l'utilisation de lamelles rigides et légères d'une longueur et d'une largeur considérables soit souhaitable et, le recours à des plaques profilées creuses extrudées en aluminium vient immédiatement à l'esprit. Dans la pratique cependant, il est impossible d'extruder de tels profilés avec une grande largeur désirée, par exemple de 60 cm. C'est pourquoi il est nécessaire d'assembler deux plaques profilées plus étroites ou davantage bord contre bord. Un tel assemblage est difficile à réaliser, lorsque les éléments ont plusieurs mètres de long. La présente invention propose toutefois un procédé d'assemblage sûr réalisé de façon simple. On utilise à cet effet des plaques profilées (6,28,30) le long des bords desquelles sont prévues des membrures transversales (10,12), qui, lorsque les profilés sont placés bord contre bord, s'engagent les unes dans les autres de façon à produire un blocage dans la direction transversale, et les pièces des membruressont bloquées ensemble par introduction d'une clavette d'assemblage profilée en U ou en C (36), qui entre en contact et s'ajuste avec du jeu sur l'extérieur de ces pièces de membrures (34). La clavette d'assemblage (36) peut être introduite manuellement sur toute la longueur des profilés et, malgré le jeu de l'ajustage, il est néanmoins possible d'obtenir un joint résistant et serré, étant donné que les longs profilés ne présentent jamais en pratique une extension totalement rectiligne. Les joints sont disposés à l'intérieur de cavités ménagées dans les éléments, de façon à être invisibles et non saillants sur les surfaces du panneau assemblé, lesquelles présentent de ce fait l'avantage d'être entièrement lisses.In large sunshade systems in particular, it is possible that the use of rigid and light strips of considerable length and width is desirable and the use of hollow extruded aluminum profile plates comes immediately in mind. In practice, however, it is impossible to extrude such profiles with a desired large width, for example 60 cm. This is why it is necessary to assemble two narrower or more profiled plates edge to edge. Such an assembly is difficult to achieve, when the elements are several meters long. The present invention however provides a safe assembly method carried out in a simple manner. For this purpose, profiled plates (6,28,30) are used along the edges of which transverse members (10,12) are provided, which, when the profiles are placed edge to edge, engage one another so as to produce a blockage in the transverse direction, and the parts of the members are locked together by introduction of a U-shaped or C-shaped assembly key (36), which comes into contact and adjusts with play on the 'exterior of these pieces of members (34). The assembly key (36) can be inserted manually over the entire length of the profiles and, despite the adjustment play, it is nevertheless possible to obtain a strong and tight seal, since long profiles never have in practice a completely straight extension. The joints are arranged inside cavities formed in the elements, so as to be invisible and non-protruding on the surfaces of the assembled panel, which therefore have the advantage of being entirely smooth.
