Abstract

The trestle possesses supporting elements (1) which consist essentially of a wire spiral (1.1) which is reinforced by a plurality of elongated reinforcing wires (1.2) which extend in the longitudinal direction or direction of helix of the wire spiral, are arranged at its periphery and are in each case firmly connected to it at the mutual contact points (1.4). The supporting elements are closed on both sides by one closing ring (1.3) in each case. Nodal elements (2), which have the form of a regular polyhedron and consist of a plurality of wire rings (2.1) which are arranged on the polyhedron boundary surfaces, are in mutual contact in pairs on the polyhedron edges, and are firmly connected to one another at the mutual contact points (2.2), serve to connect the ends of two or more supporting elements to one another. To connect the nodal elements to the ends of the supporting elements, clamping rings (3), which can be inserted, on the one hand, into the wire rings of the nodal elements and, on the other hand, into the closing rings of the supporting elements are provided. <IMAGE>

Description

Die vorliegende Erfindung betrifft ein Gestell mit Tragelementen gemäss dem Oberbegriff des Patentanspruchs 1. Tragelemente dieser Art sind beispielsweise bekannt aus der schweizerischen Patentschrift Nr. 560350. Ähnliche Tragelemente sind auch in der deutschen Auslegeschrift Nr. 2236086 beschrieben. In dieser sind auch Mittel zur Verbindung der Tragelemente angegeben. Diese Mittel sind relativ umständlich zu handhaben und verleihen dem gesamten Aufbau ein in ästhetischer Hinsicht wenig ansprechendes Aussehen.The present invention relates to a frame with supporting elements according to the preamble of claim 1. Supporting elements of this type are known, for example, from Swiss Patent No. 560350. Similar supporting elements are also described in German Patent Application No. 2236086. In this also means for connecting the support elements are specified. These agents are relatively cumbersome to use and give the entire structure an aesthetically unappealing appearance.

Aufgabe der Erfindung ist es vor allem, Mittel zur Verbindung der Tragelemente anzugeben, welche bei einfacher Handhabung einen vielseitigen und variablen Aufbau des Gestells ermöglichen und dem Gestell insgesamt einen ästhetisch befriedigenden Eindruck verleihen. Diese Aufgabe wird erfindungsgemäss gelöst durch ein Gestell mit den Merkmalen des Patentanspruchs 1.The object of the invention is above all to provide means for connecting the support elements which, with simple handling, enable a versatile and variable structure of the frame and give the frame an overall aesthetically satisfactory impression. According to the invention, this object is achieved by a frame having the features of patent claim 1.

Vorteilhafte sowie bevorzugte Ausgestaltungen des erfindungsgemässen Gestells sind in den abhängigen Ansprüchen gekennzeichnet.Advantageous and preferred configurations of the frame according to the invention are characterized in the dependent claims.

So ist für die Abschlussringe der gleiche Draht wie für die Drahtwendel verwendet. Der Durchmesser der Abschlussringe ist weiter vorzugsweise so gewählt, dass er dem Durchmesser der Drahtwendel an ihren Enden entspricht.The same wire is used for the end rings as for the wire helix. The diameter of the end rings is further preferably selected so that it corresponds to the diameter of the wire coil at its ends.

Die Drahtwendel ist vorzugsweise durch vier langgestreckte Versteifungsdrähte oder durch vier Paare von langgestreckten Versteifungsdrähten versteift, welche am Umfang der Drahtwendel mit jeweils gleichem gegenseitigem Abstand angeordnet sind. Die Steigung der Wendel ist vorzugsweise etwa gleich ihrem Durchmesser gewählt.The wire helix is preferably stiffened by four elongated stiffening wires or by four pairs of elongated stiffening wires, which are arranged on the circumference of the wire helix with the same mutual spacing in each case. The pitch of the helix is preferably chosen to be approximately equal to its diameter.

Der Durchmesser der Drahtwendel verhält sich zum Durchmesser des für sie verwendeten Drahtes vorzugsweise etwa wie 23: 1 und zum Durchmesser der Versteifungsdrähte etwa wie 30: 1, wobei der Druchmesser der Wendel vorzugsweise etwa zu 45 mm gewählt ist.The diameter of the wire helix is preferably approximately 23: 1 to the diameter of the wire used for it and to approximately 30: 1 to the diameter of the stiffening wires, the diameter of the helix preferably being selected to be approximately 45 mm.

Die Tragelemente sind um ihre Längsachse vorzugsweise rotationssymmetrisch, insbesondere zylindrisch.The support elements are preferably rotationally symmetrical about their longitudinal axis, in particular cylindrical.

Die beiden Enden der Drahtwendel fallen vorzugsweise jeweils mit einem Berührungspunkt mit einem der Versteifungsdrähte zusammen.The two ends of the wire helix preferably coincide with a point of contact with one of the stiffening wires.

Der Durchmesser der Drahtringe der Knotenelemente entspricht vorzugsweise dem Durchmesser der Abschlussringe der Drahtwendel.The diameter of the wire rings of the node elements preferably corresponds to the diameter of the end rings of the wire helix.

Die Spannringe können an ihrem äusseren Umfang mit Vorteil mit zwei mit Abstand voneinander parallel zueinander verlaufenden Umfangsnuten zur zumindest teilweisen Aufnahme und Fixierung der Drahtringe der Knotenelemente einerseits und der Abschlussringe der Tragelemente andererseits versehen sein.The tension rings can advantageously be provided on their outer circumference with two circumferential grooves spaced apart from one another and at least partially receiving and fixing the wire rings of the node elements on the one hand and the end rings of the support elements on the other.

Schliesslich können auch noch in die Spannringe einsetzbare, vorzugsweise durch Verdrehen in diesen fixierbare Abschlusselemente vorgesehen sein, welche als Halterungselemente beispielsweise zum Anschrauben des Gestells auf dem Boden, an einer Wand oder einer Decke oder auch zum Anbringen von elektrischen Anschlussmitteln verwendet werden können.Finally, it is also possible to provide end elements that can be inserted into the clamping rings, which can be fixed in place by twisting them, which can be used as holding elements, for example for screwing the frame onto the floor, on a wall or a ceiling or for attaching electrical connection means.

Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der beigefügten Zeichnungen erläutert. In diesen zeigt:

In den Figuren sind übereinstimmende Teile mit den gleichen Bezugszeichen versehen.In the figures, identical parts are provided with the same reference symbols.

In Fig. 1 sind mit 1 drei gleiche Tragelemente bezeichnet, welche über ein Knotenelement 2 jeweils im rechten Winkel miteinander verbunden sind. Ein Tragelement 1 ist in Fig. 2 nochmals für sich dargestellt. Die Tragelemente bestehen im wesentlichen aus einer zylindrischen Drahtwendel 1.1, welche durch langgestreckte Versteifungsdrähte 1.2 bzw. Paare von Versteifungsdrähten 1.2 (Fig. 1) versteift ist. An den gegenseitigen Berührungspunkten, wie beispielsweise beim Berührungspunkt 1.4 (Fig. 2) sind die Drahtwendel und die Versteifungsdrähte fest miteinander verbunden, wobei die Verbindung vorzugsweise eine Schweiss- bzw. Punktschweissverbindung ist. Abgeschlossen werden die Tragelemente jeweils beidseitig durch Abschlussringe, welche mit 1.3 bezeichnet sind. Die beiden Enden der Drahtwendel 1.1 fallen jeweils mit einem Berührungspunkt mit einem der Versteifungsdrähte 1.2 zusammen.In Fig. 1, three identical support elements are designated by 1, which are each connected at right angles via a node element 2. A support element 1 is shown again in FIG. 2. The support elements consist essentially of a cylindrical wire coil 1.1, which is stiffened by elongated stiffening wires 1.2 or pairs of stiffening wires 1.2 (FIG. 1). At the mutual points of contact, such as at point of contact 1.4 (FIG. 2), the wire helix and the stiffening wires are firmly connected to one another, the connection preferably being a welded or spot-welded connection. The support elements are closed on both sides by end rings, which are designated 1.3. The two ends of the wire coil 1.1 each coincide with a point of contact with one of the stiffening wires 1.2.

Das Knotenelement 2 ist im gewählten Beispielsfall, für eine rechtwinklige Verbindung mehrerer Tragelemente 1 miteinander, ein Würfel. Es besteht aus insgesamt sechs Ringen, von denen in Fig. 1 nur einer mit 2.1 bezeichnet ist. Die sechs Ringe 2.1 sind an ihren gegenseitigen Berührungspunkten, wie beispielsweise am Punkt 2.2, miteinander fest verbunden, vorzugsweise wieder durch eine Schweissverbindung. Der Durchmesser der Ringe entspricht demjenigen der Abschlussringe 1.2 der Tragelemente, wobei deren Durchmesser wiederum mit dem der Drahtwendel 1.1 übereinstimmt.In the selected example, the node element 2 is a cube for a right-angled connection of several support elements 1 to one another. It consists of a total of six rings, of which only one is designated as 2.1 in FIG. 1. The six rings 2.1 are firmly connected to one another at their mutual points of contact, such as at point 2.2, preferably again by a welded connection. The diameter of the rings corresponds to that of the end rings 1.2 of the support elements, the diameter of which in turn corresponds to that of the wire helix 1.1.

Als Verbindungselemente zwischen den Tragelementen 1 und dem Knotenelement 2 dienen Spannringe. In Fig. 1 ist nur einer der Spannringe mit 3 bezeichnet. Wie in Fig. 3 und 4 zu erkennen, bestehen die Spannringe 3 aus zwei Teilen 3.1 und 3.2. An ihrem inneren Umfang weisen die Spannringe sich diametral gegenüberliegende Stege 3.3 und 3.4 auf, in welchen Gewindebohrungen 3.5 und 3.6 für die Aufnahme von Gewindebolzen bzw. Spannschrauben vorgesehen sind. An ihrem äusseren Umfang sind die Spannringe mit zwei umlaufenden Nuten 3.7 zur Aufnahme und Fixierung der Abschlussringe 1.3 der Tragelemente 1.1 einerseits bzw. der Ringe 2.1 der Knotenelemente andererseits.Clamping rings serve as connecting elements between the supporting elements 1 and the node element 2. In Fig. 1, only one of the clamping rings is designated 3. As can be seen in FIGS. 3 and 4, the clamping rings 3 consist of two parts 3.1 and 3.2. On their inner circumference, the clamping rings have diametrically opposite webs 3.3 and 3.4, in which threaded holes 3.5 and 3.6 are provided for receiving threaded bolts or clamping screws. On their outer circumference are the clamping rings with two circumferential grooves 3.7 for receiving and fixing the end rings 1.3 of the support elements 1.1 on the one hand and the rings 2.1 of the node elements on the other.

Fig. 5 zeigt schliesslich noch ein in den Spannring 3 von Fig. 3 bzw. 4 einsetzbares Abschlusselement 4. In Aufsicht weist dieses die Form und die Grösse des in Fig. 3 mit 3.6 bezeichneten freien Innenraumes des Spannringes 3 auf und ist insofern in diesen einsetzbar. Bei Verdrehen des Abschlusselementes nach dessen Einsetzen in den genannten Innenraum 3.6 greifen die beiden Stege 3.3 und 3.4 des Spannringes in entsprechende Ausnehmungen 4.1 und 4.2 am Umfang des Abschlusselementes ein, wodurch dieses im Spannring eingeklemmt wird. Es können zusätzlich noch in den Zeichnungen nicht dargestellte Rastnocken vorgesehen sein, um das Abschlusselement in der verdrehten Stellung zu sichern. Mit 4.3 ist noch eine im Abschlusselement vorgesehene Bohrung bezeichnet, welche beispielsweise zur Aufnahme einer Schraube dienen kann, wenn das erfindungsgemässe Gestell irgendwo angeschraubt werden soll.Finally, FIG. 5 shows an end element 4 that can be inserted into the tension ring 3 of FIGS. 3 and 4. When viewed from above, this has the shape and size of the free interior of the tension ring 3, designated 3.6 in FIG. 3, and is therefore in this applicable. When the end element is rotated after it is inserted into the interior 3.6 mentioned, the two webs 3.3 and 3.4 of the clamping ring engage in corresponding recesses 4.1 and 4.2 on the circumference of the end element, as a result of which the latter is clamped in the clamping ring. In addition, locking cams (not shown in the drawings) can be provided in order to secure the end element in the rotated position. 4.3 also designates a bore provided in the end element, which can serve, for example, to hold a screw if the frame according to the invention is to be screwed on somewhere.
