Description

Die Erfindung betrifft ein Gitterwerk aus mehreren Stäben, die über Knoten miteinander verbunden sind und jeder Stab an seinem Ende ein dem Verbinden an dem Knoten dienendes Anschlußteil aufweist und der Knoten ein räumlicher Hohlkörper ist, der Rundstäbe aufweist, die über Eckteile miteinander verbunden sind, wobei das Anschlußteil den Rundstab eines Knotens umgreift und von den Eckteilen des Knotens seitlich flankiert ist.The invention relates to a latticework comprising a plurality of bars which are connected to one another via nodes and each bar has at its end a connecting part which serves to connect to the node and the node is a three-dimensional hollow body which has round bars which are connected to one another via corner parts, wherein the connecting part engages around the round rod of a knot and is flanked laterally by the corner parts of the knot.

Gitterwerke der gattungsgemäßen Art sind aus der WO 87/03346 bekannt. An einem plattenförmigen Hohlkörper sind an der Stirnseite Rundstäbe angebracht, die von einem aus zwei Halbschalen gebildeten Anschlußteil umfaßt werden, die stirnseitig in den Stab eingeschoben sind. Die Fixierung erfolgt über einen auf dem Anschlußteil nach außen weisenden Nocken, welcher in eine im Stab befindliche Öffnung einrastet. Es handelt sich um ein Faltgestänge, das sich zur Herstellung dreidimensionaler Gitterwerke nur sehr bedingt eignet, da bei räumlich fixierten Knoten die Befestigung eines Stabes dazwischen nicht mehr möglich ist, da aufgrund des Erfordernisses des stirnseitigen Einschiebens des Anschlußteiles in den Stab eine Abstandsänderung zwischen beiden Knoten zwingend erforderlich ist. Zudem ist der Zusammenbau und das Auseinanderlegen umständlich und zeitraubend. Aus der FR-A 1 268 388 ist ein aus einer Vielzahl von Stäben aufgespanntes dreidimensionales Raumfachwerk bekannt, die unmittelbar miteinander über nach Art von Gabeln gebildeten Anschlußteilen verbunden sind, dergestalt, daß die Gabel auf den benachbarten Stab aufgeschoben wird. Die Möglichkeit der Variation der räumlichen Anordnung sind erheblich eingeschränkt durch die Tatsache, daß nur zwei Stäbe miteinander verbindbar sind und zum anderen durch den zwischen beiden durch das Anschlußstück fest vorgegebenen Winkel. Hinzu kommt, daß für bestimmte Anwendungsbereiche, wie z.B. Messebau, neben einer leichten Veränderung der Konstruktion des Gitterwerkes gleichzeitig ein rasches Verbinden und Zerlegen möglich sein soll. Aus der FR-A-2 331 745 ist allgemein die Verbindung von Stäben über Knoten, die Polyeder darstellen, bekannt, an deren Kanten die Stäbe über spitz zu laufende Anschlußteile befestigt sind. Eine Verwendung dieser Knotenkonstruktion bei Stäben, die als Anschlußteile Gabeln aufweisen, ist deshalb ungeeignet, da aufgrund des durch die Gabel bedingten Umgreifens der Kanten eine gegenseitige räumliche Behinderung der benachbarten Stäbe im Inneren des Polyeders bereits beim Einhaken entstehen würde.Latticework of the generic type are known from WO 87/03346. On a plate-shaped hollow body, round rods are attached to the front side, which are encompassed by a connecting part formed from two half-shells, which are pushed into the rod on the end side. The fixation takes place via a cam which points outwards on the connecting part and which engages in an opening in the rod. It is a folding linkage that is only suitable to a limited extent for the production of three-dimensional lattice works, since with spatially fixed nodes it is no longer possible to attach a rod in between, since a change in the distance between the two nodes is required due to the requirement that the connecting part be inserted into the rod at the end is imperative. In addition, assembly and disassembly is cumbersome and time consuming. From FR-A 1 268 388 a three-dimensional space framework spanned from a multiplicity of rods is known, which are directly connected to one another via connecting parts formed in the manner of forks, in such a way that the fork is pushed onto the adjacent rod. The possibility of varying the spatial arrangement is considerably restricted by the fact that only two rods can be connected to one another and, on the other hand, by the angle which is fixed between the two by the connecting piece. In addition, for certain areas of application, such as Exhibition stand construction, in addition to a slight change in the construction of the latticework, rapid connection and disassembly should also be possible. From FR-A-2 331 745 the connection of rods via nodes, which represent polyhedra, is generally known, at the edges of which the rods are fastened by means of connecting parts which run to a point. The use of this knot construction on rods which have forks as connecting parts is therefore unsuitable since, due to the encompassing of the edges caused by the fork, a mutual spatial hindrance of the adjacent rods inside the polyhedron would already arise when hooking.

Hiervon ausgehend hat sich die Erfindung die Verbesserung derartiger Gitterwerke dahingehend zur Aufgabe gemacht, daß der Anschlußwinkel zwischen Stab und Knoten veränderbar ist sowie der Zusammenbau wesentlich rascher durchführbar ist. Gelöst wird diese Aufgabe durch die im Kennzeichen des Anspruches 1 angegebenen Merkmale.Proceeding from this, the invention has made it its object to improve such lattice works in such a way that the connection angle between the rod and the node can be changed and the assembly can be carried out much more quickly. This object is achieved by the features specified in the characterizing part of claim 1.

Das Aufbringen des als Gabel geformten Anschlußteiles auf den Knoten erfolgt über eine Bewegung des Stabes in radiale Richtung, wobei dessen Kante umgriffen wird. Die Festlegung erfolgt über eine Arretierung, die bewirkt, daß nach dem Aufschieben des Anschlußstückes auf den Knoten diese Lage beibehalten wird. Der als Würfel ausgebildete Knoten nimmt an seinen Kanten das Anschlußteil auf, die als Rundstab ausgebildet sein müssen, damit jeder denkbare Anschlußwinkel verwirklichbar ist. Die Kanten des Würfels sind deshalb Rundstäbe, die über Eckteile miteinander in Verbindung stehen. Die seitliche Flankierung der Gabel durch die Eckteile hat zur Folge, daß eine axiale Verschiebung unterbunden wird und eine zusätzliche Stabilität und seitliche Abstützung erreicht wird.The connection part, which is shaped as a fork, is attached to the knot by moving the rod in a radial direction, the edge of which is gripped. The determination is made via a lock, which ensures that this position is maintained after the connector is pushed onto the node. The node, which is designed as a cube, receives the connection part at its edges, which must be designed as a round rod so that every conceivable connection angle can be realized. The edges of the cube are therefore round bars that are connected to each other via corner parts. The side flanking of the fork by the corner parts has the result that axial displacement is prevented and additional stability and lateral support is achieved.

Als konkrete bauliche Realisierung der Arretierung der Gabel auf dem Knoten sind zwei Möglichkeiten angeboten. Als besonders vorteilhaft wird angesehen, wenn die Festlegung erfolgt über einen auf der Innenseite des Schenkels der Gabel federnd angebrachten Nocken. Während des Aufschiebens wird der Nocken beiseite gedrückt und kehrt mit Erreichen der Endposition wieder in seine ursprüngliche Lage zurück und bewirkt auf diese Weise die Arretierung des Anschlußteiles. Form und Querschnitt des Stabes sind hierbei grundsätzlich unerheblich, jedoch ist eine großflächige Anlage, d.h. kreisförmige Berandung am günstigsten, ebenso wie die Ausbildung des Nockens. Lediglich für den Durchmesser der Kante gilt, daß dessen Außendurchmesser zum Zwecke des Aufschiebens gleich oder geringer als die lichte Weite der Gabel gewählt werden muß.Two options are offered as a concrete structural realization of the fork being locked on the knot. It is considered to be particularly advantageous if the fixing takes place via a cam which is resiliently mounted on the inside of the leg of the fork. During the pushing on, the cam is pressed aside and returns to its original position when the end position is reached, and in this way locks the connecting part. The shape and cross-section of the rod are fundamentally irrelevant here, but a large area, i.e. circular edges are the cheapest, as is the formation of the cam. Only for the diameter of the edge applies that its outer diameter must be chosen equal to or less than the clear width of the fork for the purpose of sliding on.

In einer alternativen Art der Befestigung des Anschlußteiles wird zur Arretierung an Stelle der Nocken eine Federklammer vorgeschlagen, die von außen her zwischen die beiden Schenkel der Gabel eingeschoben und dort festgelegt werden kann. Hierzu ist die Gabel innenseitig komplementär zur Federklammer geformt. Nach dem Einsetzen bewirkt die Federklammer eine Arretierung der von der Gabel aufzunehmenden stabförmigen Kante. Zur Montage wird die Gabel als erstes aufgesetzt und anschließend die Federklammer zwischen die Schenkel bis zur Anschlagsposition eingeschoben und dort festgelegt. Zum Lösen der Verbindung wird in umgekehrter Reihenfolge die Federklammer entfernt und die Gabel abgezogen. Auch hier ist als Vorteil anzusehen, daß die Zug- und Druckbelastungen des Stabes vollständig über die Gabel übertragen werden und nicht durch die Federklammer selbst bestimmt und begrenzt werden. Die Belastbarkeit des Stabes bleibt voll erhalten.In an alternative way of fastening the connecting part, a spring clip is proposed for locking instead of the cams, which can be inserted from the outside between the two legs of the fork and fixed there. For this purpose, the fork is shaped on the inside complementary to the spring clip. After insertion, the spring clip locks the rod-shaped edge to be picked up by the fork. For assembly, the fork is placed first and then the spring clip is inserted between the legs up to the stop position and fixed there. To release the connection, the spring clip is removed in reverse order and the fork is removed. Here, too, it is to be regarded as an advantage that the tensile and compressive loads on the rod are transmitted completely via the fork and are not determined and limited by the spring clip itself. The Resilience of the rod remains fully intact.

Der Vorteil durch Verwendung des erfindungsgemäßen Anschlußteiles besteht einmal darin, daß der Winkel zwischen Stab und Knoten grundsätzlich beliebig gewählt werden kann, so daß sich Gitterwerke mit unterschiedlichen und/oder veränderbaren Bauhöhen durch ein und denselben Knoten lediglich durch Veränderung des Anschlußwinkels realisieren lassen. Darüberhinaus lassen sich gekrümmte Konstruktionen mit allerdings unterschiedlich langen Stäben als Diagonalen aufbauen. Zusätzlich ist der Montageaufwand sehr gering, da kein Verschrauben oder langwieriges Festlegen am Knoten vorzunehmen ist. Die Befestigung erfolgt durch Aufpressen des Anschlußteiles bzw. des Stabes in radialer Richtung und das Lösen der Verbindung durch Aufbringen einer entsprechenden Kraft in entgegengesetzter Richtung. Evtl. muß noch die Gabel über die Federklammer geöffnet oder geschlossen werden.The advantage of using the connecting part according to the invention is that the angle between the rod and the node can in principle be chosen as desired, so that latticework with different and / or changeable heights can be realized by one and the same node only by changing the connection angle. In addition, curved constructions can be constructed as diagonals with rods of different lengths. In addition, the assembly effort is very low because there is no screwing or lengthy fixing at the node. The attachment is carried out by pressing the connecting part or the rod in the radial direction and the connection is released by applying a corresponding force in the opposite direction. Possibly. the fork must still be opened or closed using the spring clip.

Die Anbringung auf dem dem Stab zugewandten Schenkel erlaubt Anschlußteil und Stab nach wie vor maximal auf Zug zu belasten, da eine Reduzierung der maximal übertragbaren Kräfte durch den Nocken aufgrund der fehlenden Notwendigkeit der elastischen Ausbildung des gegenüberliegenden Schenkels der Gabel nicht stattfindet. Bei Zug wird der gegenüberliegende Schenkel der Gabel belastet und die Druckbeanspruchung wird über Anschlußteil und Nocken sowie Stange problemlos übertragen. Die Zug- und Druckbelastung des Stabes bleibt bei der in der vorgeschlagenen Weise erfolgten Anordnung des Nockens voll erhalten In einer zweckmäßigen Ausgestaltung wird vorgeschlagen, daß die die Kanten verbindenden Ecken in ihrem Außendurchmesser gleich dem des Anschlußteiles sind. Im eingesetzten Zustand ergeben sich aus Ecken und Anschlußteilen gebildete stufenlose Übergänge.The attachment on the leg facing the rod still allows the connecting part and rod to be subjected to maximum tensile stress, since a reduction in the maximum transmissible forces by the cam does not take place due to the lack of the need for elastic formation of the opposite leg of the fork. When pulling, the opposite leg of the fork is loaded and the pressure load is easily transmitted via the connecting part and cams and rod. The tensile and compressive load of the rod remains fully intact in the arrangement of the cam in the proposed manner. In an expedient embodiment, it is proposed that the corners connecting the edges have the same outer diameter as that of the connecting part. When inserted, stepless transitions are formed from corners and connecting parts.

In einer Weiterbildung ist vorgesehen, das Anschlußteil auf den Stab endseitig aufzusetzen und hierdurch zu befestigen.In a further development it is provided that the connecting part is placed on the end of the rod and thereby fastened.

Schließlich ist bevorzugt, Nocken und Gabel einstückig, d.h. aus einem einzigen Teil herzustellen.Finally, it is preferred that the cam and fork are in one piece, i.e. made from a single part.

Weitere Einzelheiten, Merkmale und Vorteile der Erfindung lassen sich dem nachfolgendem Beschreibungsteil entnehmen, indem anhand der Zeichnung Ausführungsbeispiele der Erfindung näher erläutert werden.Further details, features and advantages of the invention can be found in the following description part, in which exemplary embodiments of the invention are explained in more detail with reference to the drawing.

Es zeigen:

  • Figur 1 einen Knoten mit einem über Nokken festlegbaren Stab,
  • Figur 2 einen Stab mit Federklammer.
Show it:
  • FIG. 1 shows a knot with a rod that can be fixed via cams,
  • Figure 2 shows a rod with spring clip.

In Figur 1 sind ein Knoten 1 sowie ein Stab 2 mit daran befestigtem, ebenfalls gemäß der Erfindung geformtem Anschlußteil 3 in perspektivischer Darstellung widergegeben und zwar in für den gegenseitigen Eingriff geeigneter Position.In Figure 1, a node 1 and a rod 2 with attached, also formed according to the invention connector 3 is shown in perspective and in a position suitable for mutual engagement.

Zunächst zum Knoten 1. Er ist von der Form eines Würfels und weist als Kanten zwölf Rundstäbe 4 auf, die über im vorliegenden Fall nach außen zu gerundeten Eckteilen 5 miteinander verbunden sind.First to the node 1. It is in the form of a cube and has twelve round bars 4 as edges, which are connected to one another via corner parts 5 which are rounded outwards in the present case.

Der darauf zu befestigende Stab 2 weist einen Anschlußteil 3 auf, welches nach Art einer Gabel 6 gebildet ist, dessen Achse senkrecht zu der des Stabes 2 verläuft. Zur Arretierung sind auf der dem Stab (2) zugewandten Seite des Schenkels der Gabel 6 zwei Nocken 7 federnd angebracht, die nach dem Aufschieben und Umgreifen der Rundstäbe 4 für das Festlegen und Arretieren sorgen. Durch reines Aufpressen läßt sich die Montage dann durchführen.The rod 2 to be fastened thereon has a connecting part 3, which is formed in the manner of a fork 6, the axis of which extends perpendicular to that of the rod 2. For locking, two cams 7 are resiliently mounted on the side of the leg of the fork 6 facing the rod (2), which cams are fixed and locked after the round rods 4 have been slid on and gripped around. The assembly can then be carried out by simply pressing on.

Um ein Aufbringen des Anschlußteiles 3 auf Rundstab 4 zu ermöglichen, muß einmal die lichte Weite der Gabel 6 gleich oder (etwas) größer als der Außendurchmesser des Rundstabes 4 gewählt werden und die senkrecht zur Achse des Stabs gemessene Länge des Anschlußteiles 3 gleich oder geringer als der Abstand benachbarter Eckteile 5. Das Anschlußteil 3 ist auf der Stirnseite des Stabes 2 und in diesem teilweise eingreifend festgelegt.In order to enable the connection part 3 to be attached to the round rod 4, the inside width of the fork 6 must be chosen equal or (somewhat) larger than the outside diameter of the round rod 4 and the length of the connection part 3 measured perpendicular to the axis of the rod must be equal to or less than the distance between adjacent corner parts 5. The connecting part 3 is fixed on the end face of the rod 2 and partially engaging in it.

In der Zeichnung ist lediglich ein einziger Stab 2 mit Anschlußteil 3 relativ zum Knoten 1 wiedergegeben. Doch stellt es den Regelfall dar, daß mehrere bis zu maximal zwölf Anschlußteile 3 und demzufolge auch die daran befestigten Stäbe 2 an ein und dem selben Knoten 1 befestigbar sind.In the drawing, only a single rod 2 with connection part 3 is shown relative to node 1. But it is the normal case that several up to a maximum of twelve connecting parts 3 and consequently also the rods 2 attached to them can be attached to one and the same node 1.

Figur 2 stimmt mit dem in Figur 1 gezeigten Stab 2 im Hinblick auf Anschluß 3 bzw. Gabel 6 weitgehend überein, mit dem entscheidenden Unterschied jedoch, daß an Stelle der Nocken eine Federklammer 8 eingezeichnet ist, die nach dem Aufsetzen der Gabel 6 auf die Rundstäbe 4, also dem in der Zeichnung wiedergegebenen Zustand aufgeschoben wird, sich hierbei an den Rundstab 4 anlegt und in die beiden Schenkeln der Gabel 6 zur Arretierung eingreift. Die Funktion des Arretierens erfolgt in der gezeigten Ausführungsform nicht über Nocken sondern über die Federklammer 8.Figure 2 coincides largely with the rod 2 shown in Figure 1 with regard to connection 3 or fork 6, with the decisive difference, however, that instead of the cams a spring clip 8 is shown, which after placing the fork 6 on the round rods 4, that is, the state shown in the drawing is pushed on, in this case lies against the round rod 4 and engages in the two legs of the fork 6 for locking. In the embodiment shown, the locking function does not take place via cams but via the spring clip 8.

Im Ergebnis erhält man durch Verwendung der Stäbe 2 mit den erfindungsgemäßen Anschlußteilen 3 und/oder dem vorgeschlagenen Knoten 1 Gitterwerke von räumlichen Struckturen, die aufgrund des beliebig einstellbaren Anschlußwinkels zwischen Knoten 1 und Stab 2 beliebige Bauhöhen mit ein und demselben Knoten herstellen und realisieren lassen, wobei insbesondere im Falle der Verwendung der erfindungsgemäßen Anschlußteile 3 die Verbindung zwischen Stab 2 und Knoten 1 einfach herstellbar ist.As a result, by using the rods 2 with the connecting parts 3 according to the invention and / or the proposed node 1, lattice structures of spatial structures are obtained which, due to the connection angle between node 1 and rod 2, which can be set as desired, can be used to manufacture and realize any construction heights with one and the same node, the connection between rod 2 and node 1 being easy to produce, in particular if the connecting parts 3 according to the invention are used.

Claims (5)

1. Lattice rods that are connected together by means of joints (1) and each rod (2) having at its end a connecting member (3) serving to connect with said joint (1), whereby said joint (1) comprises a three dimensional hollow body having round rods (4), which are connected together by means of corner pieces (5), whereby said connecting member (3) embraces the round rod (4) of a joint (1) and is flanked by said corner pieces (5) of said joint (1) wherein said hollow body comprises a cube, whose edges form said round rods (4) and said connecting member (3) comprises a fork (6), whose axis extends vertically to rod (2) and as locking means comprises either a spring- mounted cam (7) on the interior of one shank of said fork (6) or is lockable at the end by means of a spring clip (8).
2. Lattice rods according to claim 1 wherein said cam (7) is disposed on the rod side of the shank.
3. Lattice rods according to claims 1 or 2 wherein the external diameter of said corner pieces (5) connecting said edges (4) is equal to that of said connecting member (3).
4. Lattice rods according to one of the claims 1 to 3 wherein said connecting member (3) is disposed on said rod (2).
5. Lattice rods according to one of the claims 1 to 4 wherein said cam (7) and fork (6) are of one piece.
