Description

Die Erfindung betrifft ein Bauelement für Baukastensystem, beispielsweise für den Gerüstbau. Dabei sind sowohl begehbare Gerüste als auch Gerüste für den Spielzeugbau denkbar.The invention relates to a component for a modular system, for example for scaffolding. Both walkable scaffolds and scaffolds for toy construction are conceivable.

Gerüste werden derzeit aus Stangen oder Stäben zusammengebaut, die sowohl senkrecht als auch horizontal angeordnet sind. Diese Teile werden mittels Schrauben untereinander verbunden und aneinander befestigt, welche durch entsprechende Löcher an bzw. in den Bauelementen gesteckt und mit Hilfe von Muttern in der Montageposition gesichert werden. Derartige Gerüste sind nicht nur kostspielig, sondern erfordern auch viel Handarbeit für den Auf- und Abbau.Scaffolding is currently being assembled from bars or rods that are arranged both vertically and horizontally. These parts are connected to each other by means of screws and fastened to each other, which are inserted through corresponding holes on or in the components and secured in the assembly position with the aid of nuts. Such scaffolds are not only expensive, but also require a lot of manual work for assembly and disassembly.

Der Erfindung liegt die Aufgabe zugrunde, ein einfach aufgebautes und auch einfach und zweckmäßig zu verwendendes Bauelement für Baukasten­systeme, beispielsweise für den Gerüstbau zu schaffen, das sich leicht handhaben läßt und insbesondere wenig Handarbeit erfordert, wenn man aus derartigen Bauelementen beispielsweise ein Gerüst aufbaut.The invention has for its object to provide a simply constructed and also simple and expedient to use component for modular systems, for example for scaffolding, which is easy to handle and in particular requires little manual labor if you build a scaffold from such components.

Diese Aufgabe wird erfindungsgemäß mit einem Bauelement gelöst, welches einen stangen- oder stabartigen Grundkörper aufweist, an dessen beiden Enden je ein Stecker mit profiliertem Querschnitt vorgesehen ist. Im Gegensatz zu bekannten Gerüsten ist es mit dem erfindungsgemäßen Bau­element möglich, durch einfache Steckverbindungen beliebige Gerüste od.dgl. aufzubauen, wobei die Steckverbindung im allgemeinen ausreicht, um die einzelnen Teile eines derartigen Gerüstes oder sonstigen Bau­kastensystems ausreichend fest miteinander zu verbinden.This object is achieved according to the invention with a component which has a rod-like or bar-like base body, at the two ends of which a connector with a profiled cross section is provided. In contrast to known scaffolding, it is possible with the component according to the invention, any scaffolding or the like by simple plug connections. build up, the plug connection is generally sufficient to connect the individual parts of such a scaffold or other modular system sufficiently firmly together.

Nach einem bevorzugten zweckmäßigen Ausführungsbeispiel der Erfindung ist das Querschnittsprofil der Stecker achteckig. Ein derartiges Quer­schnittsprofil ermöglicht eine gute formschlüssige Verbindung zwischen den zusammenzusteckenden einzelnen Bauelementen, wobei der Stecker sowohl positiv als auch negativ ausgebildet sein kann, d.h. entweder ein Steck­element oder eine Aufnahme für ein derartiges Steckelement sein kann. Aufgrund der achteckigen Ausbildung des Querschnittes lassen sich die erfindungsgemäßen Bauelemente einfach und ohne darauf achten zu müssen, wie deren Position zueinander genau ist, schnell zusammenbauen.According to a preferred expedient embodiment of the invention, the cross-sectional profile of the connector is octagonal. Such a cross-sectional profile enables a good interlocking connection between the individual components to be plugged together, the plug being able to be both positive and negative, i.e. can either be a plug element or a receptacle for such a plug element. Due to the octagonal design of the cross section, the components according to the invention can be assembled quickly and easily without having to pay attention to how their positions are relative to one another.

Nach einem weiteren Merkmal der Erfindung weist das Querschnittprofil der Stecker eine flache wellenförmige Kontur auf. Eine derartige Kontur hat den Vorteil, daß sie sich im Spritzguß aus Kunststoff mit verhältnis­mäßig einfachen Werkzeugen herstellen läßt, da die entsprechenden Werk­zeuge keine Hinterschneidungen aufweisen müssen. Andererseits wurde gefunden, daß ein derartiges Querschnittsprofil ausreicht, um eine form­schlüssige Steckverbindung ausreichender Festigkeit zu erzielen. Dabei können die Toleranzen der zusammenpassenden Querschnittsprofile so ge­wählt werden, daß auch eine auf Reibung basierende ausreichend feste kraftschlüssige Steckverbindung erzielt wird, welche gewährleistet, daß aus derartigen Bauelementen zusammengesteckte Gebilde wie Gerüste mit ausreichender Stabilität zusammenhalten.According to a further feature of the invention, the cross-sectional profile of the plug has a flat, wavy contour. Such a contour has the advantage that it can be injection molded from plastic with relatively simple tools, since the corresponding tools do not have to have undercuts. On the other hand, it was found that such a cross-sectional profile is sufficient to achieve a positive connection of sufficient strength. The tolerances of the matching cross-sectional profiles can be selected so that a friction-based, sufficiently strong, force-locking plug-in connection is achieved, which ensures that structures such as scaffolds that are put together from such components hold together with sufficient stability.

Nach einem weiteren Merkmal der Erfindung können am stangen- oder stab­artigen Grundkörper des erfindungsgemäßen Bauelementes radial zu diesen verlaufende stab- oder stangenförmige Ansätze mit jeweils einem Stecker am äußeren Ende vorgesehen sein. Derartige Bauelemente lassen sich als Eckverbinder für den Gerüstbau bzw. zum Anschließen mehrerer einfacher stangen- oder stabartiger Grundkörper oder Bauelemente verwenden.According to a further feature of the invention, rod-shaped or rod-shaped extensions, each with a plug at the outer end, can be provided on the rod-like or base-like base body of the component according to the invention. Such components can be used as corner connectors for scaffolding or for connecting several simple rod-like or rod-like base bodies or components.

Obwohl es besonders vorteilhaft ist, das erfindungsgemäße Bauelement aus Kunststoff herzustellen, vorzugsweise zu spritzen, kann es auch aus anderen Materialien wie Metall bestehen.Although it is particularly advantageous to produce the component according to the invention from plastic, preferably by injection, it can also consist of other materials such as metal.

  • Figure 2 is a perspective view of another component with several radially extending lugs, all parts having a positive connector at their ends, and
  • Figure 3 is an enlarged cross-section of the profile of the connector according to the invention, from which the wavy shape of the contour of these connectors can be seen.

Das in Figur 1 dargestellte Bauelement (1) hat einen stangenartigen Grundkörper (2), an dessen einem Ende ein positiver Stecker (3) mit profiliertem Querschnitt vorgesehen ist, während das anderen Ende ein Sackloch (4) enthält, das dieselbe Kontur wie der Stecker (3) aufweist und somit zum Einstecken des Steckers (3) eines entsprechenden oder ähnlich ausgebildeten Bauelementes geeignet und bestimmt ist.The component (1) shown in Figure 1 has a rod-like base body (2), at one end of which a positive plug (3) with a profiled cross section is provided, while the other end contains a blind hole (4) which has the same contour as the plug (3) and is therefore suitable and intended for inserting the plug (3) of a corresponding or similarly designed component.

Die Querschnittsform des Steckers (3) und des Sackloches (4) ist in Figur 3 im einzelnen dargestellt und wird weiter unten näher erläutert.The cross-sectional shape of the plug (3) and the blind hole (4) is shown in detail in Figure 3 and is explained in more detail below.

Das Bauelement (5) aus Figur 2 hat ebenfalls einen stangenartigen Grund­körper (6), an dessen beiden Enden jeweils ein positiver Stecker (3) angeordnet ist. Außerdem sind etwa im mittleren Bereich des Grundkörpers (6) radial vorstehende stangenförmige Ansätze (7) vorgesehen, im darge­stellten Ausführungsbeispiel insbesamt vier derartige Ansätze, wobei jeder dieser Ansätze (7) am äußeren Ende einen positiven Stecker (3) aufweist. Dieses Bauelement (5) ist als Eckverbindung oder Knoten für ein Gerüst geeignet, wobei an diesen Knoten Bauelemente (1) der in Figur 1 dargestellten Art angebaut werden können, indem man diese stangenartigen Bauelemente mit deren Sackloch (4) auf die Stecker (3) des Bauelementes (5) aufsteckt.The component (5) from Figure 2 also has a rod-like base body (6), at the two ends of which a positive plug (3) is arranged. In addition, radially protruding rod-shaped lugs (7) are provided approximately in the central region of the base body (6), in the exemplary embodiment shown a total of four such lugs, each of these lugs (7) having a positive plug (3) at the outer end. This component (5) is suitable as a corner connection or node for a scaffold, components (1) of the type shown in FIG. 1 being able to be attached to this node by placing these rod-like components with their blind holes (4) on the connectors (3). the component (5).

Obwohl beim Bauelement gemäß Figur 1 am einen Ende ein positiver Stecker (3) und am anderen Ende ein Sackloch (4), d.h. also ein negativer Stecker, vorgesehen ist, können auch beide Enden des Bauelementes (1) gleich ausgebildet sein. Ebenso ist es möglich, beim Bauelement (5) gemäß Figur 2 an den Enden des stangenartigen Grundkörpers (6) und der Ansätze (7) anstelle der dort gezeigten positiven Stecker (3) auch negative Stecker in Form von Sacklöchern (4) vorzusehen. Man wird für den jeweiligen Anwendungsfall die jeweils zweckmäßigste Ausführungsform wählen.Although in the component according to FIG. 1 there is a positive plug (3) at one end and a blind hole (4) at the other end, i.e. that is, a negative connector is provided, both ends of the component (1) can also be of identical design. It is also possible for the component (5) according to FIG. 2 to also provide negative plugs in the form of blind holes (4) at the ends of the rod-like base body (6) and the lugs (7) instead of the positive plugs (3) shown there. You will choose the most appropriate embodiment for each application.

Figur 3 zeigt, daß die Stecker (3) im Querschnitt eine etwa achteckige Kontur aufweisen, wobei die Konturlinie (8) in Form flacher Wellen ver­läuft, um Hinterschneidungen zu vermeiden. Die Sacklöcher (4) haben eine entsprechende Kontur, so daß Stecker (3) in Sacklöcher (4) passen. Dabei ist darauf geachtet, daß die Konturlinie keine Hinterschneidungen aufweist, so daß die Profile mit verhältnismäßig einfachen Werkzeugen beispielsweise im Spritzguß aus Kunststoff hergestellt werden können.Figure 3 shows that the connector (3) have an approximately octagonal cross-section, the contour line (8) in the form of flat waves to avoid undercuts. The blind holes (4) have a corresponding contour so that plugs (3) fit into blind holes (4).
