Description

Die vorliegende Erfindung betrifft eine Wand mit länglichen Gliedern, welche mittels Knotenstücken untereinander verbunden sind, wobei das jeweilige längliche Glied einen rohrförmigen Abschnitt und uenigstens ein Endstück aufweist, wobei eine Partie des Endstückes im rohrförmigen Abschnitt spielfrei sitzt und wobei das Knotenstück mit Aufnahmepartien für die zweite und ausserhalb des rohrförmigen Abschnittes befindliche Partie der Endstücke versehen ist.The present invention relates to a wall with elongate members which are connected to one another by means of knot pieces, the respective elongate member having a tubular section and at least one end piece, one part of the end piece sitting in the tubular section without play and the knot piece with receiving parts for the second and part of the end pieces located outside the tubular section is provided.

Eine Wand dieser Gattung bildet einen der Bestandteile eines zusammensetzbaren Verkaufsstandes, welcher in DE-B 1.082.711 offenbart ist. Dieser Verkaufsstand enthält zusammenklappbare Rohrgerüste, welche Rohrstützen und Streben umfassen.A wall of this type forms one of the components of an assembled sales stand, which is disclosed in DE-B 1,082,711. This booth contains collapsible pipe scaffolds that include pipe supports and struts.

Zwei Rohrstützen, welche hintereinander geschaltet sind, sind mit Hilfe eines Verbindungsstückes miteinander verbunden. Die einander zugewandten Endpartien der Rohrstützen sind mit je einer Oese versehen. An den im wesentlichen ringförmigen Oesenkörper schliesst sich ein Schraubbolzen an, welcher in einer Mutter eingeschraubt ist, die in der betreffenden Endpartie der Rohrstütze befestigt ist. Das Verbindungsstück besteht aus zwei sich in einem Abstand voneinander befindlichen Platten, welche länglich oder dreieckförmig sein können. In den Randpartien dieser Platten sind Oeffnungen ausgeführt. Zwischen den Platten liegen die Oesen der Rohrstützen, wobei die Oeffnung in der jeweiligen Oese mit sich entsprechenden Oeffnungen in den Platten fluchtet. Durch diese Oeffnungen geht eine Hohlniete hindurch, welche die zwei Platten zusammenhält und um welche die Oese herum schwenken kann.Two pipe supports, which are connected in series, are connected to each other with the help of a connecting piece. The facing end parts of the pipe supports are each provided with an eyelet. A screw bolt adjoins the essentially ring-shaped eyelet body, which is screwed into a nut which is fastened in the relevant end section of the pipe support. The connector consists of two spaced plates, which can be elongated or triangular. Openings are made in the edge areas of these plates. The eyelets of the pipe supports lie between the plates, the opening in the respective eyelet being aligned with corresponding openings in the plates. A hollow rivet passes through these openings, which holds the two plates together and around which the eyelet can pivot.

Zwischen den Oeffnungen in den Platten, welche den Oesen der Rohrstützen zugeordnet sind, befinden sich weitere und ebenfalls miteinander fluchtende Oeffnungen in den Platten, durch welche ein Bolzen hindurchgeht. Die Endpartie jener Strebe, welche zwischen den Rohrstützen zwischengeschaltet werden soll, ist ebenfalls mit einer Oese versehen. Der Körper dieser Oese ist in seinem vorderen Bereich jedoch ausgeschnitten, so dass es sich vielmehr um eine Gabel ahndelt. Diese Gebel kann zwischen die beiden Platten des Verbindungsstückes derart eingeführt werden, dass der Bolzen zwischen den Zinken der Gabel zu liegen kommt. Diese Oese und somit auch die ganze Strebe können um den Bolzen innerhalb eines bestimmten Bereiches schwenken.Between the openings in the plates, which are assigned to the eyelets of the pipe supports, there are further openings, likewise aligned with one another, in the plates, through which a bolt passes. The end of the strut that is to be interposed between the pipe supports is also provided with an eyelet. The body of this eyelet is cut out in its front area, so that it is more like a fork. This bracket can be inserted between the two plates of the connecting piece in such a way that the pin comes to rest between the prongs of the fork. This eyelet and thus the entire strut can pivot around the bolt within a certain range.

Als besonders nachteilig gilt bei einer derartigen Verbindung von länglichen Gliedern der Umstand, dass die Strebe sich von den Rohrstützen entfernt, wenn auf die Strebe Zug einwirkt, dessen Richtung der Oeffnungsrichtung der Gabel entgegengesetzt ist. Es müssen zusätzliche Massnahmen getroffen werden, damit die Strebe mit den Rohrstützen in Verbindung bleibt. Ausserdem besteht ein Spiel zwischen dem Gewindebolzen und der im Rohrstück eingelassenen Mutter. Bei einer Wand, welche aus vielen rohrförmigen Gliedern besteht, würden sich die Spiele in den Endpartien dieser rohrförmigen Glieder summieren, was zu einer kaum annehmbaren Instabilität der Wand führen würde.A particular disadvantage of such a connection of elongated members is the fact that the strut moves away from the pipe supports when the strut acts on the strut, the direction of which is opposite to the opening direction of the fork. Additional measures must be taken so that the strut remains connected to the pipe supports. In addition, there is play between the threaded bolt and the nut embedded in the pipe section. With a wall that consists of many tubular members, the games would be in the End portions of these tubular members add up, which would lead to unacceptable instability of the wall.

Die Aufgabe der vorliegenden Erfindung ist, diese und noch weitere Nachteile der vorbekannten Wand zu beseitigen.The object of the present invention is to eliminate these and still further disadvantages of the previously known wall.

Diese Aufgabe wird bei der Wand der eingangs genannten Gattung durch eine Massnahme gelöst, die im kennzeichnenden Teil des Anspruchs 1 definiert ist.This object is achieved in the wall of the type mentioned at the outset by a measure which is defined in the characterizing part of claim 1.

Die Wand gemäss Fig. 1 weist steife und längliche Glieder 1 auf. Diese Glieder 1 bilden Paare 8, wobei die Glieder 1 des jeweiligen Paares 8 sich an einer Stelle 18, vorteilhaft in der Mitte derselben, kreuzen. Die Wand umfasst eine Anzahl solcher Gliedpaare 8. Bei dem jeweiligen Paar 8 liegen jeweils zwei Endpartien der sich kreuzenden Glieder 1 an einer Seite der Kreuzungsstelle 18. Man kann auch sagen, dass die Endpartien der länglichen Glieder 1 eines Paares 8, welche zu einer Seite der Kreuzungsstelle 18 liegen, sich in einer Ebene befinden, die senkrecht zu jener Ebene steht, in der die Glieder 1 dieses Paares 8 wenigstens annähern liegen. Die Ebene, in der die Glieder 1 eines Paares 8 liegen, wird im nachstehenden als Hauptebene dieses Paares 8 bezeichnet werden. Ferner kann man sagen, dass die gegenüberliegenden Enden der länglichen Glieder 1 eines Paares 8 in zwei parallel zueinander stehenden und sich in einem Abstand voneinander befindlichen Ebenen 5 und 6 liegen und dass die Kreuzungsstelle 18 etwa in der Mitte der Distanz zwischen diesen Ebenen 5 und 6 ist. Die Glieder 1 des jeweiligen Paares können im Bereich ihrer Kreuzungsstelle 18 gelenkig miteinander verbunden sein. Vorteilhaft erfolgt dies mit Hilfe eines Zapfens (nicht dargestellt), welcher durch die sich kreuzenden und aufeinander aufliegenden Partien der länglichen Glieder 1 hindurchgeht.The wall according to FIG. 1 has rigid and elongated members 1. These links 1 form pairs 8, the links 1 of the respective pair 8 crossing at a point 18, advantageously in the middle thereof. The wall comprises a number of such link pairs 8. In the respective pair 8, two end portions of the intersecting links 1 lie on one side of the crossing point 18. It can also be said that the end portions of the elongated links 1 of a pair 8, which to one side the intersection 18 are located in a plane that is perpendicular to the plane in which the links 1 of this pair 8 are at least approximately. The plane in which the links 1 of a pair 8 lie will be referred to below as the main plane of this pair 8. It can also be said that the opposite ends of the elongated members 1 of a pair 8 lie in two planes 5 and 6 which are parallel to one another and at a distance from one another, and that the crossing point 18 is approximately in the middle of the distance between these planes 5 and 6 is. The links 1 of the respective pair can be connected to one another in an articulated manner in the region of their crossing point 18. This is advantageously done with the help of a pin (not shown) which passes through the intersecting and superimposed parts of the elongated Links 1 passes.

Das jeweilige Gliedpaar 8 kann innerhalb der Wand derart angeordnet sein, dass seine Hauptebene entweder in einer horizontalen oder in einer vertikalen Ebene liegt, wie dies in Fig. 1 dargestellt ist. Aus Fig. 1 ist ferner ersichtlich, dass die Gliedpaare 8 sich in ihrer Längsrichtung aneinander anschliessen können, so dass die Wand horizontal und vertikal verlaufende Reihen von sich kreuzenden Gliedpaaren 8 aufweist, wobei diese Reihen sich zudem noch gegenseitig kreuzen können.The respective pair of links 8 can be arranged within the wall in such a way that its main plane lies either in a horizontal or in a vertical plane, as shown in FIG. 1. From Fig. 1 it can also be seen that the pairs of links 8 can adjoin each other in their longitudinal direction, so that the wall has horizontally and vertically running rows of intersecting pairs of links 8, these rows also being able to cross each other.

Die Endpartie des jeweiligen länglichen Gliedes 1 ist an einer Stelle eines Knotenstückes 2 angeschlossen, das einen weiteren Bestandteil der Wand darstellt. Die Wand weist eine Anzahl solcher Knotenstücke 2 auf. Die Aufgabe dieser Knotenstücke 2 ist, die Endpartien der länglichen Glieder 1 der an einer Stelle der Wand zusammentreffenden Paare 8 untereinander zu verbinden. Wie bereits erwähnt worden ist, liegen die Endpartien der länglichen Glieder 1 eines Paares 8 in einer der zwei sich in einem Abstand voneinander befindlichen Ebenen 5 und 6. In diesen Ebenen 5 und 6 befinden sich auch die Knotenstücke 2. Das jeweilige Knotenstück 2 ist so ausgebildet, dass an diesem die Endpartien mehrerer länglicher Glieder 1 angeschlossen sein können. An einem solchen Knotenstück 2 können die Endpartien zweier aufeinander folgenden Gliedpaare 8 angeschlossenen sein, die in derselben, d.h. horizontalen oder vertikalen Ebene liegen. An einem Knotenstück 2 können jedoch auch die Endpartien jener Glieder 1 angeschlossen sein, welche zu rechtwinklig zueinander stehenden Gliedpaaren 8 bzw. zu sich kreuzenden Reihen von Gliedpaaren 8 gehören.The end part of the respective elongate member 1 is connected at a point of a node piece 2, which is a further part of the wall. The wall has a number of such node pieces 2. The purpose of these knot pieces 2 is to connect the end parts of the elongated members 1 of the pairs 8 meeting at one point on the wall. As has already been mentioned, the end parts of the elongated links 1 of a pair 8 lie in one of the two planes 5 and 6 which are at a distance from one another. In these planes 5 and 6 there are also the knot pieces 2. The respective knot piece 2 is like this formed that the end portions of several elongated links 1 can be connected to this. The end parts of two successive pairs of links 8 connected in the same, i.e. horizontal or vertical plane. However, the end parts of those links 1 which belong to link pairs 8 which are at right angles to one another or to rows of link pairs 8 which cross each other can also be connected to a node piece 2.

Die länglichen Glieder 1 und die Knotenstücke 2 bilden zusammen ein Gerüst bzw. ein Skelett, welches eine vordere Fläche und eine hintere Fläche aufweist, wobei die Knotenstücke 2 in diesen Flächen liegen. Diese Flächen entsprechen den bereits besprochenen Ebenen 5 und 6 und sie begrenzen die vorliegende Wand vorne und hinten. Man kann diese Flächen auch als vordere Teilwand 5 und hintere Teilwand 6 bezeichnen. Zwischen diesen Teilwänden 5 und 6 verlaufen die sich kreuzenden Gleider 1 des jeweiligen Paares 8.The elongated members 1 and the node pieces 2 together form a frame or skeleton, which has a front surface and a rear surface, the node pieces 2 lying in these surfaces. These areas correspond to levels 5 and 6 already discussed and they delimit the present one Wall front and back. These surfaces can also be referred to as the front partial wall 5 and the rear partial wall 6. The intersecting slides 1 of the respective pair 8 run between these partial walls 5 and 6.

Da die Länge der länglichen Glieder 1 in den Paaren 8 gleich ist, befinden sich die Endpartien dieser Glieder 1 an einander gegenüberliegenden Stellen der zwei genannten Teilwände 5 und 6. Um den Abstand zwischen diesen Teilwänden 5 und 6 einstellen oder ändern zu können, erstrecken sich Distanzorgane 9 zwischen den Teilwänden 5 und 6. Die Länge dieser Organe 9 ist kleiner als die Länge der länglichen Glieder 1. Die Distanzorgane 9 erstrecken sich praktisch senkrecht zu den Ebenen der Teilwände 5 und 6 und sie können ein Stück Faden, Draht oder dgl. enthalten. Die Enden solcher Organe 9 können in bekannter Weise, beispielsweise mit Hilfe von Haken, an jenen Knotenstücken 2 angeschlossen sein, welche sich an den sich entsprechenden und gegenüberliegenden Stellen der Teilwände 5 und 6 befinden. Bei Belastung auf Zug und Druck können diese Organe 9 jedoch auch als steife Gebilde ausgeführt sein.Since the length of the elongated links 1 in the pairs 8 is the same, the end parts of these links 1 are located at mutually opposite locations of the two partial walls 5 and 6 mentioned. In order to be able to adjust or change the distance between these partial walls 5 and 6, extend Spacers 9 between the partitions 5 and 6. The length of these members 9 is less than the length of the elongated members 1. The spacers 9 extend practically perpendicular to the planes of the partitions 5 and 6 and they can be a piece of thread, wire or the like. contain. The ends of such organs 9 can be connected in a known manner, for example with the aid of hooks, to those node pieces 2 which are located at the corresponding and opposite locations of the part walls 5 and 6. When subjected to tension and pressure, these organs 9 can, however, also be designed as rigid structures.

Ferner ist das jeweilige Knotenstück 2 so ausgebildet, dass an diesem auch Frontplatten 3 und Seitenplatten 4 befestigt sein können, welche weitere Bestandteile der vorliegenden Wand darstellen. Die Frontplatten 3 bilden Bestandteile der genannten Teilwände 5 und 6. Die Seitenplatten 4 stehen dagegen senkrecht zu den Frontplatten 3 bzw. zu den Teilwänden 5 und 6. Hierbei können die Seitenplatten 4 entweder horizontal oder vertikal liegen. Wenn die Seitenplatten 4 horizontal angeordnet sind, dann können sie als Tablare verwendet werden. Wenn sie vertikal angeordnet sind, dann können sie als Seitenabschluss der Wand dienen.Furthermore, the respective node piece 2 is designed such that front panels 3 and side panels 4, which represent further components of the present wall, can also be fastened to it. The front panels 3 form components of the partial walls 5 and 6 mentioned. The side panels 4, on the other hand, are perpendicular to the front panels 3 and to the partial walls 5 and 6. Here, the side panels 4 can be either horizontal or vertical. If the side plates 4 are arranged horizontally, then they can be used as trays. If they are arranged vertically, they can serve as a side end of the wall.

Das jeweilige längliche Glied 1 (Fig. 2 bis 4) weist einen rohrförmigen Abschnitt 7 auf, wobei wenigstens einem Ende dieses Rohres 7 ein Endstück 10 zugeordnet ist. Dieses Endstück 10 ist im wesentlichen ebenfalls länglich bzw. stabförmig und es weist unter anderem eine erste und praktisch bolzenförmige Partie 11 auf. Diese erste Partie 11 des Endstückes 10 dient zum Anschluss dieses an den rohrförmigen Abschnitt 7 des länglichen Gliedes 1. Der Durchmesser des Endstückbolzens 11 bzw. der Anschlusspartie 11 des Endstückes 10 ist hinsichtlich des Innendurchmessers des Rohres 7 derart bemessen, dass die Anschlusspartie 11 im Rohr 7 festsitzt, d.h. spielfrei angeordnet ist. Die Festigkeit dieses Anschlusses kann dadurch erhöht werden, dass besondere Befestigungsmittel verwendet werden. Man kann beispielsweise eine Schicht aus einem geeigneten Klebstoff zwischen der Aussenwand der Anschlusspartie 11 und der Innenwand des Rohres 7 anbringen. Das Rohr 7 sollte aus einem möglichst leichten Material, wie z.B. aus Aluminium, Kohlefasern oder dgl. sein, damit das Gerippe der Wand möglichst leicht ist. Das Endstück 10 kann aus einem geeigneten Kunststoff sein. Zur Verbindung solcher Materialien kann als Klebstoff beispielsweise Araldit verwendet werden. Als Befestigungsmittel kommen auch eine Schraube oder ein Niet in Frage, welche quer durch das Rohr 7 und die Anschlusspartie 11 verlaufen.The respective elongate member 1 (FIGS. 2 to 4) has a tubular section 7, an end piece 10 being assigned to at least one end of this tube 7. This tail 10 is essentially also elongated or rod-shaped and it has, inter alia, a first and practically bolt-shaped section 11. This first part 11 of the end piece 10 is used to connect it to the tubular section 7 of the elongate member 1. The diameter of the end piece bolt 11 or the connecting part 11 of the end piece 10 is dimensioned with respect to the inner diameter of the tube 7 such that the connecting part 11 in the tube 7 is stuck, ie is arranged without play. The strength of this connection can be increased by using special fasteners. For example, a layer of a suitable adhesive can be applied between the outer wall of the connection part 11 and the inner wall of the tube 7. The tube 7 should be made of the lightest possible material, such as aluminum, carbon fibers or the like, so that the structure of the wall is as light as possible. The end piece 10 can be made of a suitable plastic. Araldite, for example, can be used as an adhesive to bond such materials. A screw or a rivet, which run across the tube 7 and the connection part 11, can also be used as fastening means.

Damit die länglichen Glieder 1 eine maximale Steifigkeit bei einer gegebenen Wanddicke bzw. einem gegebenen Gewicht derselben aufweisen, sind die Rohre 7 mit in ihrer Längsrichtung verlaufenden Rillen (nicht dargestellt) versehen. Diese Längsrillen können in der Aussenwand oder/und in der Innenwand des Rohres 7 ausgeführt sein.So that the elongated members 1 have maximum rigidity for a given wall thickness or a given weight thereof, the tubes 7 are provided with grooves (not shown) running in their longitudinal direction. These longitudinal grooves can be made in the outer wall and / or in the inner wall of the tube 7.

Die zweite und sich ausserhalb des Rohres 7 befindliche Partie 12 des Endstückes 10 dient zur Verbindung des länglichen Gliedes 1 mit einem der Knotenstücke 2 der vorliegenden Wand. Zu diesem Zweck weist diese Verbindungspartie 12 des Endstückes 10 Mittel zur Herstellung bzw. Lösung der Verbindung zwischen dem länglichen Glied 1 und einem der Knotenstücke 2 auf. Diese Mittel sind derart ausgeführt, dass keine Werkzeuge zur Betätigung derselben erforderlich sind und dass keine Verletzung der Hände der diese Mittel betätigenden Person durch diese Mittel möglich ist.The second part 12 of the end piece 10, which is located outside the tube 7, serves to connect the elongate member 1 to one of the knot pieces 2 of the present wall. For this purpose, this connecting part 12 of the end piece 10 has means for establishing or releasing the connection between the elongate member 1 and one of the node pieces 2. These means are designed in such a way that no tools are required to operate them and that there is no injury to the hands the person operating these means is possible through these means.

Die Verbindungspartie 12 des Endstückes 10 weist im Bereich des Ueberganges zur Anschlusspartie 11 einen Kragen 13 auf, an den sich ein etwa prismaförmiger Abschnitt 20 des Endstückes 10 anschliesst. Die Aussenwand des Kragens 13 ist praktisch zylinderförmig. Der Durchmesser des Kragens 13 ist allerdings grösser als der Durchmesser des bolzenförmigen Verbindungsstückes 11, so dass der Kragen 13 eine praktisch ringförmige Stirnfläche 14 aufweist, die dem bolzen 11 zugewandt ist. An dieser Stirnfläche 14 schlägt die Stirnfläche 15 der Oeffnung im zugeordneten Ende des Rohres 7 an, wenn das Endstück 10 im Rohr 7 eingesetzt ist.The connecting part 12 of the end piece 10 has a collar 13 in the region of the transition to the connecting part 11, to which an approximately prismatic section 20 of the end piece 10 is connected. The outer wall of the collar 13 is practically cylindrical. The diameter of the collar 13 is, however, greater than the diameter of the bolt-shaped connecting piece 11, so that the collar 13 has a practically annular end face 14 which faces the bolt 11. At this end face 14, the end face 15 of the opening strikes in the associated end of the tube 7 when the end piece 10 is inserted in the tube 7.

Der sich an den Kragen 13 anschliessende Abschnitt 20 der Verbindungspartie 12 hat im wesentlichen die Form eines geraden Prismas, wobei die Seitenkanten dieses Prismas 20 praktisch parallel zur Längsachse des Endstückes 10 verlaufen. Der Querschnitt dieses Prismas 20 ist im wesentlichen viereckig. Fig. 3 zeigt jene Seitenwand 27 dieses Prismas 20, welche der längeren Seite des genannten Viereckes entspricht und welche somit eine grössere Fläche aufweist als jene Seitenwand 28 des Prismas 20, welche der kürzeren Seite des Viereckes entspricht. Im prismaförmigen Endstückabschnitt 20 ist ein Einschnitt 21 senkrecht zu den genannten grösseren Seitenflächen 27 desselben ausgeführt. Zu je einer Seite dieses Einschnittes 21 befindet sich je ein Schenkel 23 bzw. 24, welche die restlichen Teile des prismaförmigen Abschnittes 20 des Endstückes 10 darstellen. Der Anfang des Einschnittes 21 schliesst sich an die freie Stirnfläche 22 des prismatischen Abschnittes 20 an, die gekrümmt verläuft.The section 20 of the connecting part 12 adjoining the collar 13 has essentially the shape of a straight prism, the side edges of this prism 20 running practically parallel to the longitudinal axis of the end piece 10. The cross section of this prism 20 is essentially square. 3 shows that side wall 27 of this prism 20 which corresponds to the longer side of the said quadrilateral and which therefore has a larger area than that side wall 28 of the prism 20 which corresponds to the shorter side of the quadrilateral. In the prism-shaped end section 20, an incision 21 is made perpendicular to the said larger side surfaces 27 thereof. On each side of this incision 21 there is a leg 23 or 24, which represent the remaining parts of the prism-shaped section 20 of the end piece 10. The beginning of the incision 21 adjoins the free end face 22 of the prismatic section 20, which is curved.

Parallel zu den grösseren Seitenflächen 27 des prismaförmigen Endstückabschnittes 20 und etwa in der Mitte desselben ist eine schlitzförmige Oeffnung 26 ausgeführt, welche sich zwischen den kleineren Seiten 28 des Prismas 20 erstreckt und welche zur Aufnahme eines Greifrades 30 bestimmt ist. Dieses Greifrad 30 sitzt auf einer Welle 31, welche durch die Schlitzöffnung 26 quer hindurchgeht und deren Enden in den gegenüberliegenden und die Schlitzöffnung 26 seitlich begrenzenden Wänden 27 gelagert sind. Der sich von der gekrümmten Stirnfläche 22 her erstreckende und geradlinig verlaufende Schlitz 21 ist so lang ausgeführt, dass sein Boden 25 sich im Bereich der vertikal verlaufenden Schlitzöffnung 26 befindet. Der horizontale und vorne offene Schlitz 21 überdeckt somit teilweise die schlitzförmige Oeffnung 26.Parallel to the larger side surfaces 27 of the prism-shaped end section 20 and approximately in the middle thereof, a slot-shaped opening 26 is made, which is between the extends smaller sides 28 of the prism 20 and which is intended for receiving a gripping wheel 30. This gripping wheel 30 is seated on a shaft 31 which passes transversely through the slot opening 26 and the ends of which are mounted in the opposite walls 27 which laterally delimit the slot opening 26. The straight slot 21, which extends from the curved end face 22, is of such a length that its bottom 25 is located in the region of the vertical slot opening 26. The horizontal slot 21, which is open at the front, thus partially covers the slot-shaped opening 26.

Das Greifrad 30 weist einen gekrümmten Schlitz 32 auf, welcher parallel oder beinahe parallel zur Umfangsrichtung bzw. zur Umfangskontur des Rades 30 verläuft. An eine der Endpartien dieses gekrümmten Schlitzes 32 schliesst sich ein Durchbruch 33 im Greifrad 30 an, welcher sich von der Umfangskontur des Greifrades 30 bis zum gekrümmten Schlitz 32 erstreckt und an diesen sich anschliesst. Der Durchbruch 33 zusammen mit dem gekrümmten Schlitz 32 bilden eine etwa L-förmige Bahn, die zur wahlweisen Ergreifung einer einen der Bestandteile des Knotenstückes 2 bildenden Achse 45 dient.The gripping wheel 30 has a curved slot 32 which runs parallel or almost parallel to the circumferential direction or to the circumferential contour of the wheel 30. At one of the end parts of this curved slot 32 there is an opening 33 in the gripping wheel 30 which extends from the circumferential contour of the gripping wheel 30 to the curved slot 32 and adjoins this. The opening 33 together with the curved slot 32 form an approximately L-shaped path which is used for the optional gripping of an axis 45 forming one of the components of the node piece 2.

In einem Bereich des Greifrades 30, der etwa diametral zu jenem Bereich desselben gegenüberliegt, in dem sich der besprochene gekrümmte und offene Schlitz 32 befindet, ist ein weiterer Schlitz 36 ausgeführt, der zwar auch gekrümmt ist, der jedoch geschlossen ist. In diesem zweiten und praktisch gleich gekrümmten Schlitz 36 des Greifrades 30 liegt ein Zapfen 37, der in der Innenwand der schlitzförmigen Oeffnung 26 befestigt ist. Die Länge des zweiten gekrümmten Schlitzes 36 bestimmt die Länge des Schwenkbereïches des Greifrades 30 um seine Welle 31. Die Lage des Zapfens 37, die Lage des zweiten Schlitzes 36 innerhalb des Greifrades 30 und die Länge dieses Schlitzes 36 sind derart bemessen, dass bei einer der Anschlagslagen des Begrenzungszapfens 37 an einem Ende des zweiten Schlitzes 36 der Durchbruch 33 im Greifrad 30 der Endpartie des geradlinig verlaufenden Schlitzes 21 im Prisma 20 gegenübersteht. Bei der anderen Anschlagslage des Zapfens 37 im geschlossenen Schlitz 36 befindet sich das andere Ende des offenen Schlitzes 32 im Bereich der inneren Endpartie des geradlinigen Schlitzes 21.In a region of the gripping wheel 30, which lies approximately diametrically opposite to the region in which the curved and open slot 32 discussed is located, a further slot 36 is made, which is also curved, but which is closed. In this second and practically equally curved slot 36 of the gripping wheel 30 there is a pin 37 which is fastened in the inner wall of the slot-shaped opening 26. The length of the second curved slot 36 determines the length of the pivoting area of the gripping wheel 30 about its shaft 31. The position of the pin 37, the position of the second slot 36 within the gripping wheel 30 and the length of this slot 36 are dimensioned such that in one of the Stop positions of the limiting pin 37 at one end of the second slot 36 of the Breakthrough 33 in the gripping wheel 30 faces the end part of the rectilinear slot 21 in the prism 20. In the other stop position of the pin 37 in the closed slot 36, the other end of the open slot 32 is in the region of the inner end part of the straight slot 21.

Vor allem aus technologischen Gründen kann das Endstück 10 aus zwei praktisch gleich ausgebildeten Hälften bestehen, wobei die diese Hälften trennende Linie 34 aus Fig. 4 deutlich ersichtlich ist. In einem solchen Fall weist das Greifrad 30 seitlichen Vorsprünge auf, welche die Welle 31 ersetzen und welche in entsprechenden Vertiefungen in den Endstückhälften gelagert sind.For technological reasons in particular, the end piece 10 can consist of two practically identical halves, the line 34 separating these halves from FIG. 4 being clearly visible. In such a case, the gripping wheel 30 has lateral projections which replace the shaft 31 and which are mounted in corresponding recesses in the end piece halves.

Das Knotenstück 2 umfasst eine Grundplatte 40, welche mit Aufnahmepartien 41 für das Endstück 10 eines der länglichen Glieder 1 versehen ist. Diese Aufnahmepartien 41 befinden sich vorteilhaft an der rückwärtigen Seite der Grundplatte 40. Sie können sich jedoch auch an der Vorderseite derselben befinden. Fig. 5 zeigt, wie die jeweilige Aufnahmepartie 41 ausgebildet ist und wie die Aufnahmepartien 41 an der rückwärtigen Seite der Grundplatte 40 angeordnet sind.The node piece 2 comprises a base plate 40, which is provided with receiving parts 41 for the end piece 10 of one of the elongated members 1. These receiving parts 41 are advantageously located on the rear side of the base plate 40. However, they can also be located on the front of the same. 5 shows how the respective receiving section 41 is designed and how the receiving sections 41 are arranged on the rear side of the base plate 40.

Die Aufnahmepartie 41 umfasst Wangen 42 und 43 (Fig. 5), welche als praktisch rechtwinklig zur Oberfläche der Grundplatte 40 stehende Platten ausgebildet sind. Die von der Grundplatte 40 entfernte Endpartie 44 dieser Platten 42 und 43 ist kreisförmig abgerundet. Die einander gegenüberliegenden flächen der Platten 42 und 43 verlaufen praktisch parallel zueinander, so dass zwischen den Wangen 42 und 43 einer Aufnahmepartie 41 ein Spalt von gleichbleibender Breite vorhanden ist. Zwischen den Wangen 42 und 43 erstreckt sich eine Achse 45, deren Enden in den Wangen 42 und 43 befestigt sind. Die Befestigungsstellen dieser Achse 45 befinden sich in einem Bereich der Wangen 42 und 43, in dessen Mitte das Zentrum des Kreisabschnittes 44 an den Wangen 42 und 43 liegt.The receiving part 41 comprises cheeks 42 and 43 (FIG. 5), which are designed as plates standing practically at right angles to the surface of the base plate 40. The end portion 44 of these plates 42 and 43 which is removed from the base plate 40 is rounded in a circle. The opposite surfaces of the plates 42 and 43 run practically parallel to one another, so that a gap of constant width is present between the cheeks 42 and 43 of a receiving part 41. An axis 45 extends between the cheeks 42 and 43, the ends of which are fastened in the cheeks 42 and 43. The fastening points of this axis 45 are located in a region of the cheeks 42 and 43, in the center of which the center of the circular section 44 lies on the cheeks 42 and 43.

Beim Einstecken des Endstückes 10 eines länglichen Gliedes 1 in eine der Aufnahmepartien 41 des Knotenstückes 2 muss zunächst sichergestellt werden, dass der Durchbruch 33 im Greifrad 30 so eingestellt ist, dass er in der Endpartie des Schlitzes 21 liegt. Dann wird der prismatische Abschnitt 20 des Endstückes 10 in die Aufnahmepartie 41 eingeführt. Hierbei gelangt die Achse 45 in den Schlitz 21 dieses Endstückes 10 und das Endstück 10 wird dann so weit in die Aufnahmepartie 41 eingeschoben, bis die Achse 45 auf dem Boden 25 des geradlinig verlaufenden Schlitzes 21 anschlägt. Diese Lage der Achse 45 ist in Fig. 2, unten dargestellt. In der letzten Phase dieses Einschubes betrat die Achse 45 den Durchbruch 33 im Greifrad 30 und am Schluss dieses Einschubes liegt sie in der Anfangspartie des offenen gekrümmten Schlitzes 32 im Greifrad 30. Nun kann man das Greifrad 30 durch die Einwirkung, beispielsweise des Daumens, auf eines der zwei aus dem Prismastück 20 hervorstehenden Segmente des Greifrades 20 derart betätigen, dass der offene Schlitz 32 im Greifrad 30 sich an der Achse 45 vorbeibewegt, wobei die Nase 34 des Greifrades 30 die Achse 45 hintergreift.When inserting the end piece 10 of an elongate member 1 into one of the receiving parts 41 of the knot piece 2, it must first be ensured that the opening 33 in the gripping wheel 30 is set such that it lies in the end part of the slot 21. Then the prismatic section 20 of the end piece 10 is inserted into the receiving part 41. Here, the axis 45 comes into the slot 21 of this end piece 10 and the end piece 10 is then inserted into the receiving part 41 until the axis 45 strikes the bottom 25 of the straight slot 21. This position of the axis 45 is shown in Fig. 2, below. In the last phase of this insertion, the axis 45 entered the opening 33 in the gripping wheel 30 and at the end of this insertion it lies in the starting part of the open curved slot 32 in the gripping wheel 30. Now the gripping wheel 30 can be opened by the action of, for example, the thumb Actuate one of the two segments of the gripping wheel 20 protruding from the prism piece 20 such that the open slot 32 in the gripping wheel 30 moves past the axis 45, the nose 34 of the gripping wheel 30 engaging behind the axis 45.

Falls der gekrümmte, offene Schlitz 32 parallel zur Randpartie des Greifrades 30 verläuft, dann wird die genannten Greifbewegung des Rades 30 durch den Anschlag entweder des Zapfens 37 am gegenüberliegenden Ende des geschlossenen gekrünmmten Schlitzes 36 oder durch den Anschlag der Achse 45 am geschlossenen Ende des offenen gekrümmten Schlitzes 32 beendet. Falls der Abstand zwischen dem offenen Schlitz 32 und dem Rand des Greifrades 30 gegen das geschlossene Ende dieses Schlitzes 32 hin zunimmt, so wird die Schliessbewegung des Greifrades 30 dann beendet, wenn die Reibung zwischen der Achse 45 und dem Material der äusseren Schlitzwand so gross ist, dass keine weitere Drehbewegung des Greifrades 30 mehr möglich ist.If the curved, open slot 32 runs parallel to the edge part of the gripping wheel 30, then said gripping movement of the wheel 30 is either by the stop of the pin 37 at the opposite end of the closed curved slot 36 or by the stop of the axis 45 at the closed end of the open curved slot 32 ended. If the distance between the open slot 32 and the edge of the gripping wheel 30 increases towards the closed end of this slot 32, the closing movement of the gripping wheel 30 is ended when the friction between the axis 45 and the material of the outer slot wall is so great that no further rotary movement of the gripping wheel 30 is possible.

Bei der Lösung dieser Verbindung wird das Greifrad 30 von Hand zurückgedreht, bis die noch im offenen Schlitz 32 liegende Achse 45 dem Durchbruch 33 gegenübersteht. Dann kann das Endstück 10 des länglichen Gliedes 1 aus der Aufnahmepartie 41 des Knotenstückes 2 ohne weiteres herausgezogen werden.When loosening this connection, the gripping wheel 30 is by hand turned back until the axis 45 still lying in the open slot 32 faces the opening 33. Then the end piece 10 of the elongate member 1 can be pulled out of the receiving part 41 of the knot piece 2 without further notice.

Wie aus Fig. 5 ersichtlich ist, weist die Grundplatte 40 einen praktisch quadratischen Grundriss auf. Jeder Seite der Grundplatte 40 ist eine Aufnahmepartie 41 zugeordnet, und zwar derart, dass die Wangen 42 und 43 der jeweiligen Aufnahmepartie 41 praktisch rechtwinklig zur betreffenden Seite stehen und dass die sich zwischen diesen Wangen 42 und 43 erstreckende Achse 45 praktisch parallel zu dieser Knotenstückseite verläuft. Aus Gründen, die im nachstehenden noch beschrieben sein werden, befindet sich die jeweilige Aufnahmepartie 41 beim in Fig. 5 dargestellten Knotenstück 2 ausserhalb des Mittelbereiches der Länge der jeweiligen Knotenstückseite.As can be seen from FIG. 5, the base plate 40 has a practically square outline. Each side of the base plate 40 is assigned a receiving section 41, in such a way that the cheeks 42 and 43 of the respective receiving section 41 are practically perpendicular to the relevant side and that the axis 45 extending between these cheeks 42 and 43 runs practically parallel to this node piece side . For reasons that will be described in the following, the respective receiving part 41 in the knot piece 2 shown in FIG. 5 is outside the central region of the length of the respective knot piece side.

Zur Verbesserung der Stabilität der Wand ist eine mehrfache Führung des Endstückes 10 in der Aufnahmepartie 41 vorgesehen.To improve the stability of the wall, multiple guiding of the end piece 10 is provided in the receiving part 41.

Die ersten Führungsmittel umfassen eine Nase 46 (Fig. 2 bis 4) am Endstück 10 und eine Furche 50 (Fig. 5) in der Grundplatte 40 des Knotenstückes 2. Die Nase 46 hat, wie dies aus Fig. 4 ersichtlich ist, plane und parallel zueinander verlaufende Seitenfwände 48 und an diese Seitenwände 48 schliesst sich vorne die bereits besprochene und gekrümmte Stirnfläche 22 (Fig. 2 und 3) an. Die Breite der Nase 46 ist kleiner als die Breite des Prismaabschnittes 20 am Endstück 10. Zwischen der Seitenwand 27 des Prismaabschnittes 20 und der Seitenwand 48 der Nase 46 gibt es somit Uebergangsflächen 49, deren Form der Form der Stirnfläche 22 praktisch gleicht, wie dies vor allem aus Fig. 3 ersichtlich ist. Da die vordere Partie des Verbindungsstückes 12 mit dem Einschnitt 21 versehen ist, der in der Ebene der Welle 31 des Greifrades 30 liegt, sind die Nase 46 und die Flächen 22 und 49 durch diesen Einschnitt 21 in zwei praktisch gleich geformte Gebilde unterteilt.The first guide means comprise a nose 46 (FIGS. 2 to 4) on the end piece 10 and a groove 50 (FIG. 5) in the base plate 40 of the knot piece 2. The nose 46 has, as can be seen in FIG. 4, plane and Side walls 48 running parallel to one another and to these side walls 48 the front face 22 already discussed and curved (FIGS. 2 and 3) connects. The width of the nose 46 is smaller than the width of the prism section 20 at the end piece 10. Between the side wall 27 of the prism section 20 and the side wall 48 of the nose 46 there are thus transition surfaces 49, the shape of which practically resembles the shape of the end surface 22, as before everything is apparent from Fig. 3. Since the front part of the connecting piece 12 is provided with the incision 21, which lies in the plane of the shaft 31 of the gripping wheel 30, the nose 46 and the surfaces 22 and 49 are divided by this incision 21 into two virtually identical shapes.

Die jeweilige Furche 50 im Knotnestück 2 hat einen praktisch rechteckigen Querschnitt, so dass sie einen Boden 51 sowie Seitenwände 52 aufweist. Wie aus Fig. 2 ersichtlich ist, weist die Furche 50 in ihrer Längsrichtung allerdings einen gekrümmten Verlauf auf, und zwar derart, dass ihr Boden 51 sich entlang dem Umfang eines Kreisbogens erstreckt, dessen Zentriwinkel etwa 90 Grad beträgt. An die Enden dieser gekrümmten Partie des Furchenbodens 51 schliessen sich geradlinige Auslaufabschnitte an. Wenn das Endstück 10 im Knotenstück 2 eingesetzt ist (Fig. 2, unten), dann liegt die Nase 46 des Verbindungsstückes 12 in der Furche 50. Die Breite der Nase 46 und die Breite der Furche 50 sind so bemessen, dass die Seitenwände 48 der Nase 46 und die Seitenwände 52 der Furche 50 möglichst spielfrei aufeinander aufliegen. Die Stirnfläche 22 an den Hälften der Nase 46 ist so geformt, dass deren form sich dem Verlauf des Furchenboden 51 möglichst nähert. Das auf der Welle 31 gelagerte längliche Glied 1 soll nämlich um diese Achse 45 möglichst frei schwenkbar sein.The respective furrow 50 in the knot piece 2 has a practically rectangular cross section, so that it has a bottom 51 and side walls 52. As can be seen from FIG. 2, the furrow 50 has a curved course in its longitudinal direction, in such a way that its bottom 51 extends along the circumference of a circular arc, the central angle of which is approximately 90 degrees. At the ends of this curved part of the furrow bottom 51 there are straight outlet sections. If the end piece 10 is inserted in the knot piece 2 (FIG. 2, below), then the nose 46 of the connecting piece 12 lies in the groove 50. The width of the nose 46 and the width of the groove 50 are dimensioned such that the side walls 48 of the Nose 46 and the side walls 52 of the furrow 50 rest on one another with as little play as possible. The end face 22 on the halves of the nose 46 is shaped in such a way that its shape approaches the course of the furrow bottom 51 as closely as possible. The elongated member 1 supported on the shaft 31 should namely be freely pivotable about this axis 45.

Zweite Mittel zur Erhöhung der Stabilität der vorliegenden Wand umfassen Schultern 55, von welchen sich je eine zwischen der grösseren Seitenwand 27 des Prismaabschnittes 20 und dem Kragen 13 befindet. Wie gesagt, ist die Aussenseite des Kragens zylinderförmig. Die Schultern 55 sind dagegen eckig. Die Breite des Verbindungsstückes 12 im Bereich der Schultern 55 ist dem Durchmesser des Kragens 13 gleich, wie dies aus Fig. 4 ersichtlich ist. Dasselbe gilt hinsichtlich der Höhe der Schultern 55 (Fig. 3). In Fig. 3 ist die hintere Kante 56 und in Fig. 4 ist die obere Kante 58 der Schultern 5 dargestellt, wobei die obere Kante 58 sich zwischen den Seitenflächen 59 der Schultern 55 erstreckt.Second means for increasing the stability of the present wall include shoulders 55, one of which is located between the larger side wall 27 of the prism section 20 and the collar 13. As I said, the outside of the collar is cylindrical. The shoulders 55, however, are angular. The width of the connecting piece 12 in the area of the shoulders 55 is the same as the diameter of the collar 13, as can be seen from FIG. 4. The same applies to the height of the shoulders 55 (Fig. 3). The rear edge 56 is shown in FIG. 3 and the upper edge 58 of the shoulders 5 is shown in FIG. 4, the upper edge 58 extending between the side surfaces 59 of the shoulders 55.

Die Breite des Prismaabschnittes 20 ist kleiner als der Durchmesser des Kragens 13. Folglich ist eine Verbindungsfläche 50 zwischen der Seitenfläche 59 einer der Schultern 55 und der entsprechenden Seitenfläche 27 des Prismaabschnittes 20 vorhanden, wobei diese Verbindungsfläche 60 zu diesen Seitenflächen 27 und 59 senkrecht verläuft. Die Verbindungsfläche 60 weist einen mittleren, gekrümmten Abschnitt 61 auf, bei dem der Krümmungsradius gleich gross ist wie bei der gekrümmten Oberseite 44 der Wangen 42 bzw. 43. Die Abmessungen der Wangen 42 und 43 und der Schultern 55 sowie die Lage derselben zueinander sind so gewählt, dass die Oberseite 44 der Wangen 42 und 43 auf der Stützfläche 61 der zugeordneten Schulter 55 aufliegt. Da die Oberseite 44 der Wangen 42 und 43 den Abschnitt eines Kreisbogens bildet, besteht die Auflage zwischen den Schultern 55 und den diesen zugeordneten Wangen 42 und 43 bei jeder Winkellage des in die Aufnahmepartie 41 eingesetzten länglichen Gliedes 1.The width of the prism portion 20 is smaller than the diameter of the collar 13. Consequently, a connecting surface 50 between the side surface 59 is one of the shoulders 55 and corresponding side surface 27 of the prism section 20 is present, this connecting surface 60 being perpendicular to these side surfaces 27 and 59. The connecting surface 60 has a central, curved section 61, in which the radius of curvature is the same as that of the curved upper side 44 of the cheeks 42 and 43. The dimensions of the cheeks 42 and 43 and the shoulders 55 and the position of the same relative to one another are so chosen that the top 44 of the cheeks 42 and 43 rests on the support surface 61 of the associated shoulder 55. Since the upper side 44 of the cheeks 42 and 43 forms the section of an arc of a circle, there is a contact between the shoulders 55 and the cheeks 42 and 43 associated therewith at every angular position of the elongate member 1 inserted in the receiving part 41.

Das Knotenstück 2 weist ferner eine Befestigungsvorrichtung 65 für Elemente auf, welche Verbindung mit anderen Teilen in einer Richtung ermöglichen, welche zu den Teilwänden 5 und 6 senkrecht steht. Diese Vorrichtung 65 umfasst einen Rumpf 66, der einerends an jener Seite der Grundplatte 40 des Knotenstückes 2 befestigt ist, an der sich auch die Partien 41 zur Aufnahme der länglichen Glieder 1 befinden. Dieser Rumpf 66 steht praktisch senkrecht zur rückwärtigen Seite der Grundplatte 40 und er ist mit einer Oeffnung 67 mit einem im wesentlichen runden Querschnitt versehen. Diese Oeffnung 67 erstreckt sich in der Längsrichtung des Rumpfes 66 und sie mündet andernends in der Vorderseite 39 der Grundplatte 40.The node piece 2 also has a fastening device 65 for elements which enable connection to other parts in a direction which is perpendicular to the part walls 5 and 6. This device 65 comprises a fuselage 66 which is fastened at one end to that side of the base plate 40 of the node piece 2 on which the parts 41 for receiving the elongate members 1 are also located. This fuselage 66 is practically perpendicular to the rear side of the base plate 40 and it is provided with an opening 67 with an essentially round cross section. This opening 67 extends in the longitudinal direction of the fuselage 66 and it opens at the other end in the front 39 of the base plate 40.

Die erst genannte Endpartie der durchgehenden Längsöffnung 67 ist mit einem Innengewinde 68 versehen. In diese Oeffnung 68 kann der Gewindebolzen eines Hakens (nicht dargestellt) eingeschraubt werden, an den der Faden des Distanzorgans 9 angeschlossen ist. Dieser Faden 9 kann zu einem anderen Haken führen, der an einem der Knotenstücke 2 der gegenüberliegenden Teilwand 5 bzw. 6 in gleicher Weise befestigt ist. Falls das Distanzorgan 9 steif sein soll, so kann dieses als eine Stange ausgeführt sein, deren Enden mit gegenläufigen Gewinden versehen sind. Diese Gewindepartien des Organs 9 können im Rumpf 66 der einander gegenüberliegenden Knotenstücke 2 in einem Arbeitsgang eingeschraubt werden.The first-mentioned end part of the continuous longitudinal opening 67 is provided with an internal thread 68. The threaded bolt of a hook (not shown) to which the thread of the spacer 9 is connected can be screwed into this opening 68. This thread 9 can lead to another hook which is attached to one of the node pieces 2 of the opposite partial wall 5 or 6 in the same way. If the spacer 9 is to be rigid, it can be designed as a rod, the ends of which are provided with opposing threads are. These threaded parts of the organ 9 can be screwed into the body 66 of the opposite node pieces 2 in one operation.

In dem sich an die Vorderseite 39 der Grundplatte 40 anschliessenden Abschnitt 70 der Längsöffnung 67 ist eine Erweiterung 70 ausgeführt und diese Erweiterung 70 dient zur Aufnahme einer der Endpartien eines Kupplungsstückes 71. In Fig. 2 ist nur diese Endpartie bzw. Spitze eines solchen Kupplungsstückes 71 dargestellt. Das Kupplungsstück 71 ist flach ausgebildet und es ist vorteilhaft aus einem Metall angefertigt. Die vorderen Eckpartien dieser Spitze sind entfernt, damit sich das Kupplungsstück 71 in die Erweiterung 70 der Oeffnung 67 leichter einführen lässt. Im sich an die Frontpartie der Spitze anschliessenden Bereich der Kupplungsstückes 71 ist je eine Vertiefung 72 in den gegenüberliegenden schmalen Seiten desselben. Der Querschnitt der Erweiterung 70 im Rumpf 66 ist viereckig, damit in dieser die beschriebene Endpartie des Kupplungsstückes, Platz finden kann.In the section 70 of the longitudinal opening 67 adjoining the front side 39 of the base plate 40, an extension 70 is implemented and this extension 70 serves to receive one of the end parts of a coupling piece 71. In FIG. 2, only this end part or tip of such a coupling piece 71 is shown shown. The coupling piece 71 is flat and is advantageously made of a metal. The front corner parts of this tip are removed so that the coupling piece 71 can be inserted more easily into the extension 70 of the opening 67. In the area of the coupling piece 71 which adjoins the front part of the tip, there is a depression 72 in the opposite narrow sides thereof. The cross section of the extension 70 in the fuselage 66 is square so that the described end part of the coupling piece can be accommodated in it.

Die andere Endpartie dieses Kupplungsstückes 71 kann gleich wie die gerade beschriebene Endpartie ausgebildet sein. Mit Hilfe eines solchen Kupplungsstückes 71 kann eines der Knotenstücke 2 in einer weiteren und daneben stehenden Wand an die erste Wand angechlossen werden. Hierbei kommen die Vorderseiten 39 der Grundplatten 40 der beiden Knotenstücke 2 aufeinander zu liegen. Die andere Endpartie des Kupplungsstückes 71 kann jedoch auch als eine Hülse mit Innengewinde ausgeführt sein (nicht dargestellt). Mit Hilfe einer in diese Hülse einführbaren Schraube können Gegenstände unterschiedlicher Art an der Wand befestigt werden.The other end part of this coupling piece 71 can be designed the same as the end part just described. With the aid of such a coupling piece 71, one of the node pieces 2 can be connected to the first wall in a further and adjacent wall. Here, the front sides 39 of the base plates 40 of the two node pieces 2 come to lie on one another. The other end part of the coupling piece 71 can, however, also be designed as a sleeve with an internal thread (not shown). With the help of a screw that can be inserted into this sleeve, objects of different types can be attached to the wall.

Es ist eine Rastvorrichtung 75 vorgesehen, welche zur wahlweisen Halterung des Kupplungsstückes 71 in der Oeffnung 67 des Knotenstückes 2 bestimmt ist. Zu dieser Rastvorrichtung 75 gehört eine Oeffnung 76, welche durch den Rumpf 66 quer hindurchgeht, und zwar in einer Region desselben, welche ausserhalb des axialen Bereiches des Rumpfes 66 liegt. Genauer gesagt, liegt diese Queröffnung 76 in jener Region der Erweiterung 70 in der Längsöffnug 67, wo sich eine der Vertiefungen bzw. einer der Einschnitte 72 des Kupplungsstückes 71 befindet, wenn dieses im Knotenstück 2 eingeführt ist. Durch die Queröffnung 76 geht ein Fangabschnitt 77 einer Rastfeder 78 hindurch, die an dieser freien Endpartie des Rumpfes 66 befestigt ist. Im dargestellten Beispiel ist die Rastfeder 78 im wesentlichen L-förmig, wobei der eine Schenkel dieser Feder 78 so geformt ist dass seine Endpartie den Fangabschnitt 77 für das Kupplungsstück 71 bildet. Dieser Fangabschnitt 77 kommt nämlich in den Einschnitt 72 zu liegen, wenn das Kupplungsstück 71 im Knotenstück 2 gehalten werden soll. Die mittlere Partie der Rastfeder 78 umgibt einen Vorsprung 79 an der Aussenseite des Rumpfes 66 und der andere Schenkel 80 der Feder 78 liegt in einer umlaufenden Rille 81 am Rumpf 66, wodurch die Feder 78 ihre Abstützung erhält.A latching device 75 is provided, which for the optional holding of the coupling piece 71 in the opening 67 of the Knot piece 2 is determined. This latching device 75 includes an opening 76 which extends transversely through the fuselage 66, specifically in a region thereof which lies outside the axial region of the fuselage 66. More precisely, this transverse opening 76 lies in the region of the extension 70 in the longitudinal opening 67, where one of the depressions or one of the incisions 72 of the coupling piece 71 is located when it is inserted in the node piece 2. A catch section 77 of a detent spring 78 passes through the transverse opening 76 and is attached to this free end part of the fuselage 66. In the example shown, the detent spring 78 is essentially L-shaped, one leg of this spring 78 being shaped in such a way that its end part forms the catching section 77 for the coupling piece 71. This catching section 77 comes to lie in the notch 72 when the coupling piece 71 is to be held in the node piece 2. The middle part of the detent spring 78 surrounds a projection 79 on the outside of the trunk 66 and the other leg 80 of the spring 78 lies in a circumferential groove 81 on the trunk 66, as a result of which the spring 78 receives its support.

Es ist bereits gesagt worden, dass die Aufnahmepartien 41 für das jeweilige längliche Glied 1 sich ausserhalb des Mittelbereiches der Länge der nächstliegenden Knotenstückseite befinden. Von der Mitte der Knotenstückgrundplatte 40 steht der ebenfalls bereits beschriebene Rumpf 66 ab. Die genannte Anordnung der Aufnahmepartien 41 bietet mehr Platz die einzelnen Bestandteile dieser Partien 41, damit die Fläche der Grundplatte 40 so klein wie möglich gehalten werden kann. Weiterer Raum für die Aufnahmepartien 41 wird dadurch gewonnen, dass der Querschnitt des Rumpfes 66 im wesentlichen viereckig ist (Fig. 5) und dass die Seiten 69 eines solchen Rumpfes 66 praktisch senkrecht zur jeweiligen Diagonale der Grundplatte 40 stehen. Die Aufnahmepartien 41 befinden sich gegenüber dem mittig angeordneten Rumpf 66 ebenfalls seitlich versetzt, wobei die Achse 45 der jeweiligen Partie 41 allerdings parallel zur nächstliegenden Knotenstückseitenwand verläuft. Die Furche 50 der jeweilige Aufnahmepartie 41 erstreckt sich bis zur nächstliegenden Seite 69 des Rumpfes 66.It has already been said that the receiving parts 41 for the respective elongate link 1 are located outside the central region of the length of the closest node piece side. The fuselage 66, which has also already been described, protrudes from the center of the node base plate 40. The aforementioned arrangement of the receiving parts 41 offers more space for the individual components of these parts 41 so that the area of the base plate 40 can be kept as small as possible. Further space for the receiving parts 41 is gained in that the cross section of the fuselage 66 is essentially square (FIG. 5) and that the sides 69 of such a fuselage 66 are practically perpendicular to the respective diagonal of the base plate 40. The receiving parts 41 are also laterally offset with respect to the centrally arranged fuselage 66, the axis 45 of the respective part 41, however, running parallel to the nearest knot side wall. The furrow 50 each Receiving part 41 extends to the nearest side 69 of the trunk 66.

Die Eckpartien der Grundplatte 40 des Knotenstückes 2 weisen durchgehende Bohrungen 83 (Fig. 5) auf. Diese Bohrungen 83 dienen zur Befestigtung der Frontplatten 3, der Seitenplatten 4, der Scharniere 90 sowie weiterer Teile an den Knotenstücken 2. Die Frontplatten 3 können aus jedem beliebigen Material und von beliebiger Dicke sein. Die Eckpartien der Frontplatten 3 weisen Oeffnungen 87 auf. In Fig. 5 ist eines der Knotenstücke 2 in einer rückwärtigen Ansicht dargestellt. Der Oeffnung in der rechten oberen Ecke dieses Knotenstückes 2, welche mit der Bezugsziffer 83 versehen ist, ist die Oeffnung 87 in der linken unteren Ecke der Frontplatte 3 zugeordnet. In dieser Weise können die Eckpartien von vier Frontplatten 3 an einem Knotenstück 2 befestigt werden, indem eine der Eckpartien der nebeneinander liegenden Frontplatten 3 einer der Eckpartien des Knotenstückes 2 zugeordnet wird.The corner parts of the base plate 40 of the node piece 2 have through bores 83 (FIG. 5). These bores 83 serve to fasten the front plates 3, the side plates 4, the hinges 90 and other parts to the node pieces 2. The front plates 3 can be made of any material and of any thickness. The corner parts of the front plates 3 have openings 87. 5 shows one of the node pieces 2 in a rear view. The opening in the upper right corner of this node piece 2, which is provided with the reference number 83, is assigned the opening 87 in the lower left corner of the front plate 3. In this way, the corner parts of four front plates 3 can be fastened to a node piece 2 by assigning one of the corner parts of the side plates 3 lying next to one another to one of the corner parts of the node piece 2.

Die Seitenplatten 4 sind in der Regel aus Blech und sie weisen rechtwinklig zur Hauptfläche derselben abgebogene Ränder 84 und 85 auf. Die seitlichen Randpartien der Platte 4 weisen je einen rechtwinklig zur Hauptfläche der Platte 4 stehenden Seitenstreifen 85 auf. In einem Bereich, der sich an den vorderen und zur Hauptfläche der Seitenplatte 4 ebenfalls rechtwinklig stehenden Frontstreifen 84 anschliesst, ist der Seitenstreifen 85 entfernt. Die Länge dieses freien Bereiches 86 ist etwas grösser als die Dicke der Grundplatte 40 des Knotenstückes 2. In den Endpartien des abgebogenen Frontstreifens 84 ist je eine Oeffnung 87 ausgeführt.
