Description

The present invention relates to a profile composite of a plurality of profile elements, an arrangement of at least two such profile composites and a node connector for such profile composites, according to the preambles of the independent claims. Such a composite profile or their arrangement can be used in countless areas of technology, thanks to their enormous versatility, such. As in mechanical engineering, apparatus construction, plant construction, storage technology, fixture, furniture, shopfitting, exhibition stand construction, steel construction, timber construction (skeleton), toy, etc., especially for substructures, bases, racks, frames, chassis, platforms or various structures.

The CH-389'853 discloses a longitudinally having post with a specially designed cross-section and points to the advantages of the longitudinal grooves. Such posts are suitable for. B. for walls, boxes, tables, doors, barriers, racks and window displays. They can be with each other or with other components such as fillings and the like or be connected in a simple manner without screws, wherein the compounds in the longitudinal grooves are infinitely positionable in the longitudinal direction.

The production of profiles for various applications can be carried out according to the prior art, on the one hand with the aid of the hot forming extrusion process. This can u. A. manufacture open profiles, tubes and hollow sections of aluminum materials. An overview of the manufacturing processes, the products and their applications is provided by the book M. Bauser, G. Sauer, K. Siegert (ed.), "Extruding", Aluminum-Verlag Dusseldorf, 2nd edition, 2001 , Extruded profiles can, as well as in the CH-389'853 disclosed posts, be provided with longitudinal grooves, which makes them versatile. Extruded profiles also have various disadvantages. So their production is complicated. For each new type of profile, a separate forming die must be produced. This is economically worthwhile only if products of this size can be produced in large quantities. Therefore, the extrusion process is unsuitable for applications in which different profiles are required in smaller quantities. Another disadvantage of extruded profiles is that they can be produced only from a few materials - mainly aluminum, besides also copper, tin or lead materials. But aluminum can not be used everywhere. It is for investments, for example unsuitable in the food industry, because it contaminates food and an existing anodizing is attacked by acids. Therefore, would be desirable profiles of other materials, eg. As steel and in particular stainless steel, brass, copper, but also wood, plastic, etc.

On the other hand, profiles produced by other methods, for example a rolling method, are known. These can in particular also be made of steel. The usual manufacturing methods for steel profiles but allow only a few, relatively simple open (T, I, Z, C, U, L and other profiles) or hollow (circular, rectangular hollow sections) cross-sectional shapes. However, these shapes do not always have the mechanical properties required for a particular application. In addition, hollow steel profiles have no longitudinal grooves, so that they can be practically connect only by welding in junctions - a complex process that you want to avoid especially on site (eg on a construction site).

In the FR-2'341'766 discloses a method for mounting support or pedestal elements on support posts. Such a support element is designed to receive one end of a threaded rod, by means of which it is pressed against two of four supporting pillars. The other end of the Threaded rod is pressed by a locknut or a second support element to the other two supporting pillars, whereby the corresponding counterforce is applied. With this method, the support element can be mounted at any height. However, the method has the disadvantage that additional elements are needed to define the mutual distance between the support pillars. Such additional elements may be plates or webs which must be clamped between the support posts. Especially in the case of webs whose positioning in the direction of the longitudinal axis can be problematic. A further disadvantage of this method is that a threaded rod only holds together two pairs of supporting pillars in a spatial direction perpendicular to the longitudinal direction, whereas a cohesion in the other spatial direction perpendicular to the longitudinal direction is not guaranteed and would have to be produced by a second threaded rod.

It is an object of the invention to provide a support or support element which can replace the known extruded profiles in many applications, but which is cheaper to manufacture and which is produced from a variety of materials. The carrier or support elements according to the invention should also have longitudinal grooves and thereby be at least equal in terms of versatility to the extruded profiles, but they should not have disadvantages of the prior art.

These and other objects are achieved by the inventive profile composite, as defined in claim 1. Further, it is an object of the invention to provide an array of multiple profile interconnects interconnected at a node by a node connector. Another object of the invention is to provide a junction connector for such profile composites. These objects are achieved by the arrangement according to the invention and the inventive node connector according to two further independent patent claims. Advantageous embodiments are given in the dependent claims.

In the inventive profile composite of a plurality of profile elements, the profile elements are arranged parallel to each other and define a longitudinal direction. The profile elements are connected by at least one connecting element. At least two of the profile elements are spaced apart such that at least one longitudinal groove extends between them. The at least one connecting element includes both connecting means for producing clamping connections between at least two of the profile elements and the at least one connecting element as well as spacing means for maintaining a well-defined mutual distance between the at least two profile elements.

Preferably, the clamping connection is such that the profile elements of the connecting means such. B. are not penetrated by screws. Any penetrating openings would weaken the profile elements at the penetration points, whereby the profile composite z. B. would be prone to kinking.

In the inventive arrangement of at least two profile composites, which are interconnected in -einem node by a node connector, the profile composites according to the invention profile composites.

The junction connector according to the invention for connecting at least two profile composites in a node has first fastening means for fastening a first profile composite and second fastening means mechanically connected to the first fastening means for fastening a second profile composite.

The profile composite according to the invention can be used virtually anywhere previously known extruded profiles were used. It can be designed so that its mechanical properties -. B. stress on bending, tension, pressure or torsion - with those of extruded profiles comparable or even better. Compared to extruded profiles, it has the advantage of being cheaper to manufacture, especially for small Quantities. In addition, the inventive composite profile opens up many other applications because it consists of a variety of materials -. As steel and especially stainless steel, from virtually all other metal materials such as aluminum, copper or brass, wood, plastic, etc. - can be produced. Any surface treatment of the inventive profile composite is possible. For the production of node connections between two inventive profile composites no post-processing - such. B. creating cross-bores - necessary. Rather, such node connections can be easily mounted at any position in the longitudinal direction thanks to inherent longitudinal grooves. Thus, the invention offers a previously unknown versatility and universality and can be used in countless technical fields.

Fig. 19

a profile element for a further embodiment of an inventive profile composite in a plan view.

In FIG. 1 a first embodiment of a novel profile composite 1 is shown in a perspective view. This embodiment includes four parallel to each other, a longitudinal direction z defining profile elements 2.1-2.4. The profile elements 2.1-2.4 are spaced apart, so that longitudinally extending longitudinal grooves 3.1-3.4 are present between them along the entire profile composite. The four profile elements 2.1-2.4 are in this embodiment hollow sections with square cross-section, for example. With side lengths of 20 mm x 20 mm and wall thicknesses of eg. 2 mm, and z. B. made of stainless steel. Such and other hollow profiles are commercially available.

Of course, the profile elements 2.1-2.4 other, z. B. have circular cross-sections, may have other dimensions, need not be hollow and may consist of various materials such as steel, aluminum, brass, copper, wood or plastic. These and other parameters will be optimized by the person skilled in the art with knowledge of the invention for the respective application. As far as the profile cross-section is concerned, it is known (see "Manufacture, Assembly and Installation of Hollow-Section Structures", ed. Comité International pour le Développement et l'Etude de la Construction Tubulaire (CIDECT), TÜV-Verlag, 1998, pp. 18f) in that hollow profiles, in particular circular hollow sections, have more advantageous mechanical properties (meter weight, moment of inertia, torsional moment of inertia) than open profiles. Therefore hollow sections are often preferred, for example in steel construction. Hollow sections can also be filled with a filling material, for example. Concrete. As far as the dimensions of the profile elements 2.1-2.4 are concerned, the invention permits a spectrum extending over several orders of magnitude: For toy building sets, the profile elements 2.1-2.4 will have side lengths of a few millimeters; for frames in mechanical engineering profile elements 2.1-2.4 are preferably used with side lengths of about 20 mm x 20 mm and wall thicknesses of about 2 mm; for steel skeleton construction Profile elements 2.1-2.4 are conceivable with side lengths of 400 mm × 400 mm or 450 mm × 250 mm and wall thicknesses of 16 mm, 20 mm or even more.

The four profile elements 2.1-2.4 are connected to each other in this embodiment by two spaced apart in the longitudinal direction connecting elements 4.1, 4.2. The connecting elements 4.1, 4.2 include both connecting means for establishing a connection between the profile elements as well as spacing means for maintaining a well-defined mutual distance, for. B. a well-defined Längsnutenbreite, between the profile elements 2.1-2.4. The number of connecting elements in a profiled composite 1 according to the invention can be one, two or more than two. For a clear and stable definition of the mutual position of the profile elements 2.1-2.4, preferably at least two connecting elements 4.1, 4.2 are used. Other fasteners may be useful, for example, to give the composite profile 1 a greater flexural rigidity in order to stabilize it against kinking or around a junction connector (see. Fig. 8-10 ). Each connecting element 4.1, 4.2 offers connection points in the form of threaded holes on all four sides ± x, ± y. A great advantage is that the connecting elements 4.1, 4.2 at any position in the longitudinal direction z, ie, infinitely attach. Other Verbindungsel.emente are can also be retrofitted into an already existing profile composite 1.

If necessary, the walls of the profile elements 2.1-2.4, for example. In an equidistant grid, positioning 21 for positioning and / or attachment of components, eg. Of cross members having. Such positioning openings 21 could be advantageous in applications in which large forces occur, for the clamping connections would be insufficient. So z. B. in steel cross member are mounted in such positioning, possibly in addition to the node connectors according to Figures 8-14 provided clamp connections. In Fig. 1 For reasons of simplicity, the positioning openings 21 are indicated on only two side surfaces of the profile elements 2.1 and 2.2. Such positioning holes 21 may, for. B. be circular or slot-shaped and attached by punching or laser machining. This is hardly possible or only with great effort in extruded profiles according to the prior art. It should be emphasized, however, that they are not necessary for the present invention; Rather, as mentioned, the stepless positioning of the connecting elements 4.1, 4.2 in the longitudinal direction z is one of the advantageous features of the inventive profile composite 1.

A preferred embodiment of a connecting element 4 is based on the FIGS. 2 and 3 explained in more detail.

FIG. 2 shows a connecting element 4 for the composite profile 1 of Fig. 1 in an exploded view. The connecting element 4 has the shape of a cross with four arms 44.1-44.4 of equal length. It may, for example, be composed of two beams 41.1, 41.2 made of stainless steel, each with a length of 51 mm and a square cross-section with a side length of 12 mm, which are overlapped with each other, but may alternatively be in one piece. The two bars 41.1, 41.2 can be screwed together with a central connecting screw 42 in a passage or threaded bore 43. The side surfaces of the four arms are provided with threaded holes 45.1-45.4, approx. 13 mm long, for holding clamping screws 46.1-46.4, eg M8 screws. The bars 41.1, 41.2 may have square, rectangular, round or any other cross section.

The mode of action of this connecting element 4 is in FIG. 3 recognizable, in the profile composite 1 of Fig. 1 is shown in cross section. The connecting element 4 includes both connecting means 46.1-46.4 for producing a clamping connection between the profile elements 2.1-2.4 and the connecting element 4 and also spacing means 44.1-44.4 for maintaining a well-defined mutual distance between the profile elements 2.1-2.4. Each profile element 2.1 is located on two adjacent arms 44.1, 44.4 of the cross-shaped connecting element 4 and is held by two clamping screws 46.1, 46.4 by clamping. A clamping screw 46.1 simultaneously connects two profile elements 2.1, 2.2 with the connecting element 4, ie presses them against the two arms 44.2 perpendicular to this clamping screw 46.1, 44.4. Thus, each profile element 2.1 is pressed with two of its surfaces against two arms 44.1, 44.4 of the connecting element 4, whereby extremely solid and stable surface pressures are achieved.

FIG. 4 shows a second embodiment of a novel profile composite 1 in cross section. This embodiment has three hollow sections 2.1-2.3 with a circular cross-section. Accordingly, the connecting element 4 is star-shaped with three arms 44.1-44.3. Each of the three arms 44.1 receives a clamping screw 46.1, which presses the two adjacent hollow sections 2.1, 2.2 against the connecting element 4 by means of a clamping element 47.1. The clamping elements 47.1-47.3 are designed as outwardly curved brackets.

A third embodiment of a profile composite 1 according to the invention is shown in a plan view in FIG FIG. 5 shown. Here are four hollow sections 2.1-2.4 with rectangular cross-section available. The connecting element 4 is designed as a frame with openings 48.1-48.4 for receiving the hollow sections 2.1-2.4. At each opening 48.1, a clamping screw 46.1 is attached to exert a clamping force on the corresponding hollow profile 2.1. Each hollow section 2.1-2.4 could also be assigned several, for example. Two mutually perpendicular, clamping screws.

A fourth embodiment of a novel profile composite 1 in a plan view shows FIG. 6 , This embodiment has z. B. four full sections 2.1-2.4 with a circular cross section. Again, the connecting element 4 is designed as a frame with openings 48.1-48.4 for receiving the solid sections 2.1-2.4. However, the frame 4 has four openings 48.1-48.4 opening into slots 49.1-49.4, so that by narrowing a slot 49.1, the diameter of the associated opening 48.1 can be reduced. This is done by introducing a clamping screw 46.1 in a designated passage or threaded hole 45.1. By tightening the clamping screw 4.6.1 creates a clamping connection between the solid profile 2.1 and the connecting element. 4

The Figures 3-6 show embodiments in which the profile elements in two dimensions (x and y in Fig. 1 ) are arranged. Of course, the invention also includes profile composites in which the profile composites in only one dimension, ie arranged in a row. So Profile composites in the form of "fences" or "walls" can be realized. A suitable connection element can, for example, in analogy to the connecting element 4 of Fig. 3 be formed comb-shaped. Between each two adjacent prongs is then a profile element, which is fastened by means of two engaging in the tines screws. In the simplest case of two profile elements, such a connecting element has the shape of an "E". Alternatively, in analogy to the connecting elements 4 of FIGS. 5 and 6 , Frame with arranged in a row openings for receiving the profile elements possible.

Furthermore, embodiments of the inventive profile composite are possible in which a connecting element not all, but z. B. connects only two of four profile composites together. A connecting element in such an embodiment may, for example, be designed as a hexagonal spacer holder with inside threaded holes on both sides. At both ends of the spacer a profile element is screwed. For this purpose, the profile elements are provided with corresponding through holes. The four profile composites can be arranged in the corners of a square, and the spacers form as it were the sides of the square.

For many applications, it will be necessary to have an arrangement 11 of a plurality of profile compounds 1.1-1.5 according to the invention in such a way to create nodes 5 by the profile composites 1.1-1.5 are connected to each other at node 5 by means of a node connector 6. Preferably, the connection should be rigid, such that the longitudinal directions of the profile composites 1.1-1.5 are different from each other, preferably perpendicular to each other. Such an arrangement 11, in which a first profile composite 1.1 is connected in a node 5 by means of a node connector with four further profile connections 1.2-1.5 lying in a plane perpendicular to the first profile composite 1.1, is shown in FIG FIG. 7 shown. In this figure, neither the connecting elements nor the node connector are shown in this figure for the sake of simplicity. All five profile groups 1.1-1.5 involved can consist of identical profile elements. But there may also be cases in which it is advantageous, for example, to construct the first profile composite 1.1 as a support made of stronger profile elements and the further profile composites 1.2-1.5 as a carrier of less strong profile elements. The invention allows all possible possibilities in this regard.

FIG. 8 shows a part of a first embodiment of an inventive node connector 6, which for the node 5 of Fig. 7 is usable, in an exploded view. The node connector 6 includes two central sub-elements 61.1, 61.2, which in such a way with each other are überblattbar that they a long drawn, central connecting element 4.1 with cross-shaped cross-section (see. Fig. 3 ) form for the first profile composite 1.1. The cross arms 64.1-64.4 have in each case in places an extension 67.1-67.4, to each of which a peripheral partial element 68.1-68.4 can be applied by overlapping. For the sake of simplicity, is in Fig. 8 only a peripheral sub-element 68.1 shown, and holes and screws for the cohesion of the overlapping with each other sub-elements are omitted. The combination of an arm extension 67.1 with the associated peripheral partial element 68.1 results in a rigidly connected to the central connecting element peripheral connecting element 4.2. The peripheral connecting element 4.2 thus serves on the one hand as a connecting element for a further profile composite 1.2, on the other hand as part of the node connector 6 for connecting the first profile composite 1.1, with the other profile composite 1.2 (see. Fig. 7 ). The sub-elements 61.1, 61.2, 68.1-68.4 are preferably screwed together, but may also be welded together.

The node connector 6 of Fig. 8 has the advantage that it is largely hidden inside the profile composites 1.1-1.5 connected by it. So he has no parts outside the profile composites 1.1-1.5, which could disturb functionally or aesthetically. noteworthy is that it can be attached to any position in the longitudinal direction z of the first profile composite 1.1, without having to take into account an existing grid or that the first profile composite 1.1 would have to be specially processed, for example. By attaching mounting holes.

While FIG. 8 a node connector for connecting a first profile composite 1.1 with four other profile connections 1.2-1.5 shows, the expert will be in the knowledge of the invention in the position to design analog node connectors for connecting only two, three or four profile composites. Of course, other than right angles to the routing of the other profile composites 1.2-1.5 can be realized.

The node connector 6 of Fig. 8 As well as the node connectors discussed below, may for example consist of structural steel, stainless steel, aluminum, etc., in the latter case preferably reinforcements are attached to the threads.

A second embodiment of an inventive node connector 6 for inventive profile composites 1.1, 1.2 is in FIG. 9 shown. This embodiment has a base plate 60 with, for example, two holes 62.1, 62.2 for screwing to corresponding connecting elements in first profile composite 1.1 (not shown), such that the base plate 60 comes to lie parallel to the longitudinal direction z of the first profile composite 1.1. On the base plate 60 is a cross-shaped connecting element 4 (see. FIGS. 2 and 3 ) in such a way - for example by means of a screw connection - attached, that its longitudinal axis is perpendicular to the base plate 60. This connecting element 4 with four arms 44.1-44.4, each carrying a threaded bore 45.1-45.4, can now (not shown) for a second profile composite 1.2 are used, which thus extends perpendicular to the first profile composite 1.1 and is connected to the same. The connecting element 4 can also be rotated in the base plate plane by, for example, 45 °, so that the second profile composite 1.2 is fastened correspondingly.

Alternatively, the base plate 60 may be used without the connector 4 as a node connector. In this case, z. B. the profile elements of the second profile composite 1.2 are welded directly to the base plate 60, so that the base plate 60 forms an end face of the second profile composite 1.2.

FIG. 10 shows a third embodiment of an inventive node connector 6 for inventive profile composites 1.1, 1.2. The node connector 6 has a first base plate 60.1 and a perpendicular, standing, with the first base plate 60.1 rigidly connected second base plate 60.2 on. Both base plates 60.1, 60.2 are each provided with a bore 62.1, 62.2 for screwing the base plates 60.1, 60.2 to corresponding connecting elements. These two connection elements belong to two mutually perpendicular, connected by the node connector 6 profile connections 1.1, 1.2 (not shown). This type of node connectors can also be used as additional reinforcement or stiffening of a node 5 together with one of the occasion of Fig. 8 or 9 discussed node connectors can be used, with at most smaller structural adjustments would be necessary.

A fourth and fifth embodiment of a node connector 6 according to the invention are shown in FIG Figures 11 or 12 is shown. The embodiment of Fig. 11 has four arms 64.1-64.3, 64.5 for fixing each one (not shown) profile element, the embodiment of Fig. 12 three arms 64.1, 64.2, 64.5. The arms 64.1-64.3, 64.5 preferably each enclose an angle of 90 ° (eg 64.1, 64.2) or of 180 (64.1, 64.3); but there are also other angles possible. They each have connecting means, for. B. the threaded holes 45.1-45.4 of Fig. 2 corresponding threaded holes, for establishing a connection with the profile elements. The embodiments of the FIGS. 11 and 12 are made of solid, overlapped sub-elements, similar like the one from Fig. 8 , The sub-elements are preferably screwed together, but can also be welded together.

Instead of flat sub-elements of the inventive node connector 6 can also be constructed of arms 64.1-64.3, 64.5, which are each made in one piece by cold rolling and cold drawing of example. Structural or bright steel.

Alternatively to the massive embodiments of FIGS. 11 and 12 For example, the junction connector 6 according to the invention can be designed in a tubular construction. An arm 64.1-64.3, 64.5 of such a node connector 6 may, for. B. consist of a central rod element with a square cross-section and four peripheral rod elements with a rectangular cross-section, wherein the peripheral rod members each attached to a side surface of the central rod element, for example, welded, are, so that in turn results in a cross-shaped cross-section. The central rod element may be hollow or made of solid material.

A sixth, less massive embodiment of an inventive node connector 6 with four arms 64.1-64.3, 64.5 show Figures 13 and 14 , The four arms 64.1-64.3, 64.5 are here designed as square bars with a relatively small cross-section. At the front of each arm is a cross-shaped connecting element 4.1-4.3, 4.5 according to Fig. 2 attached. The connecting elements 4.1-4.3, 4.5 have threaded holes 45 (FIG. Fig. 13 ) for receiving clamping screws 46 ( Fig. 14 ), whereby the (not shown) profile elements with the connecting elements 4.1-4.3, 4.5 are connectable. The arms 64.1-64.3, 64.5 of the node connector 6 are preferably welded together at node 5, but may also be bolted together. The connecting elements 4.1-4.3, 4.5 are welded to the end faces of the arms 64.1-64.3, 64.5, but could also be screwed.

FIG. 15 shows an inventive arrangement 11 of four profile composites 1.1-1.3, 1.5, which in a node 5 by the inventive node connector 6 according to Figures 13 and 14 connected to each other.

The node connection does not necessarily have to be rigid. Alternatively, it can also be moved in the node 5, z. B. articulated, as a hinge and / or as a guide, be designed so that the interconnected profile composites are movable relative to each other, for. B. rotatable and / or movable, are.

Further embodiments of inventive profile composites 1 with clamping elements 47.1-47.4 show Figures 16-18 ,

In the embodiment of FIG. 16 are the clamping elements 47.1-47.4 outside flush with the profile elements 2.1-2.4 formed so that they are not - as in the embodiment of Fig. 4 - stand out from the outside, which may be technically and aesthetically unsatisfactory in some applications. They are as exactly as possible adapted to the outer shapes of the profile elements 2.1-2.4. By means (not shown) clamping screws which engage in corresponding threaded holes in the four arms of the connecting element 4, the clamping elements 47.1-47.4 and thus also the profile elements 2.1-2.4 are pressed against the connecting element 4. The clamping screws can be sunk in the clamping elements 47.1-47.4, so that they do not interfere with the outside protrude.

In the embodiment of FIG. 17 are the clamping elements 47.1-47.4 also outwardly flush with the profile elements 2.1-2.4 formed. In the profile elements 2.1-2.4 are, however, recesses mounted in which the clamping elements 47.1-47.4 engage. The advantage over the embodiment of Fig. 16 is that the recesses provide the clamping elements 47.1-47.4 a larger attack surface. For this, the profile elements 2.1-2.4 must be machined for the purpose of attaching the recesses, which means greater effort and lower application flexibility.

The recesses can, as in Fig. 17 shown to be attached to one edge of a profile element 2.1-2.4, so that a recess engages two adjacent side surfaces. Alternatively, in each case a recess can be mounted in only one side surface. This alternative has the advantage that the clamping elements 47.1-47.4 and clamping screws are barely visible from the outside, but the disadvantage of the more complex production and the more complex assembly.

In the embodiment of FIG. 18 is in each case an angle element 22.1, for example. Of steel, at least locally attached to each profile element 2.1. The attachment can bswp. by means of longitudinal pinning with heavy-duty pins or by welding. A disc-shaped clamping element 47.1 engages the edges of two angle elements 22.1, 22.2.

The angle elements 22.1-22.4 of Fig. 18 can also be integrated in the profile elements 2.1-2.4. Such a modified profile element 2, which in its orientation to the profile element 2.4 of Fig. 18 corresponds, is in FIG. 19 shown. It is a special forming tube whose basic cross-section is derived from a square, but in which two surfaces are partially offset outwards, so that two clamping surfaces 23 are formed at the displacement points. At these clamping surfaces 23 engage (in Fig. 19 not shown) clamping elements or directly clamping screws. This embodiment is elegant in that it requires no processing of the profile elements 2.1-2.4 and a connecting element can be attached at any point.

Of course, the described exemplary embodiments may be combined with one another without departing from the invention.
