Description

Die vorliegende Erfindung betrifft ein Grundelement für die Herstellung großflächiger Platten für Baukastensysteme.The present invention relates to a basic element for the production of large-area panels for modular systems.

Es sind die unterschiedlichsten Baukastensysteme für Kinder, auch solche mit großflächigen Teilen, bekannt. Entweder sind jedoch die Formkosten bei exakter Herstellung der notwendigen unterschiedlichen großflächigen Teile unwirt­schaftlich hoch, oder diese Teile halten bei nicht exakter Formgebung durch billigere Verfahren, wie Formblasen, in zusammengebautem Zustand sehr schlecht.A wide variety of modular systems for children, including those with large parts, are known. However, either the molding costs are uneconomically high when the various large-area parts required are precisely manufactured, or these parts hold very poorly when assembled using less expensive methods, such as blow molding, in the assembled state.

Das DE-GM 7 OO7 O72 beschreibt einen Bauteilsatz für Spiel­zwecke, darunter verschieden lange, als Vierkantleisten ausgebildete Elemente mit quadratischen Durchbrüchen, welche voneinander einen Abstand haben, der einer Seitenlänge, dieser quadratischen Durchbrüche entspricht. Diese Vierkant­leisten können durch Verbindungselemente miteinander verbun­den werden.DE-GM 7 OO7 O72 describes a set of components for playing purposes, including elements of different lengths, designed as square strips, with square openings which are at a distance from one another which corresponds to a side length of these square openings. These square strips can be connected to one another by connecting elements.

Die DE-OS 3O l5 697 beschreibt einen Bausatz zum Zusammen­bauen von Spielmodellen, bestehend aus quaderförmigen Spiel­bauteilen, welche aus zwei Halbschalen zusammengesetzt sind.DE-OS 3O l5 697 describes a kit for assembling game models, consisting of cuboid game components which are composed of two half-shells.

Ziel der vorliegenden Erfindung ist ein Grundelement für die Herstellung großflächiger Platten für ein Baukastensys­tem, insbesondere für eine Steckbausteinsystem. Dieses Grundelement soll bei geringen Herstellungskosten die Erzeu­gung von Platten unterschiedlicher Größe gestatten, welche quadratische Durchbrüche in sinnvoller Anordung aufweisen.The aim of the present invention is a basic element for the production of large-area panels for a modular system, in particular for a plug-in module system. This basic element is intended to allow the production of plates of different sizes at low manufacturing costs, which have square openings in a sensible arrangement.

Dieses Ziel wird mit einem Grundelement gemäß den Patentan­sprüchen erreicht.This goal is achieved with a basic element according to the patent claims.

Das bevorzugte Grundelement ist dadurch gekennzeichnet, daß es acht Durchbrüche aufweist, die in zwei Reihen von je vier Durchbrüchen nebeneinander angeordnet sind.The preferred basic element is characterized in that it has eight openings which are arranged side by side in two rows of four openings.

Vorzugsweise beträgt der Abstand der Seitenkanten der Durch­brüche von der Außenkante des Grundelementes die Hälfte der Kantenlänge der Durchbrüche, also a/2.The distance of the side edges of the openings from the outer edge of the base element is preferably half the edge length of the openings, ie a / 2.

Bei der erfindungsgemäßen Herstellung von Platten wird auch bei unterschiedlichster Plattengröße jeweils nur ein Formwerkzeug für das Grundelement benötigt, da dieses Grund­element unter entsprechender Anordnung der Durchbrüche mit anderen Grundelementen zu allseitig geschlossenen Plat­ten zusammengefügt werden kann.In the production of plates according to the invention, only one molding tool is required for the base element, even with a wide variety of plate sizes, since this base element can be joined together with other base elements to form plates which are closed on all sides, with the openings being arranged accordingly.

Das Zusammenfügen der Grundelemente kann durch Schweißen, Kleben, Stecken, Schrauben oder auf andere geeignete Weise erfolgen.The basic elements can be joined together by welding, gluing, plugging, screwing or in another suitable manner.

Die Figuren l bis 7 zeigen das erfindungsgemäße Grundelement und daraus hergestellte Platten.Figures 1 to 7 show the basic element according to the invention and plates made therefrom.

Die Erfindung wird durch die Zeichnung näher erläutert.

  • Figur l zeigt das Grundelement in der Perspektive mit acht quadratischen Durchbrüchen und in der Ansicht von der geschlossenen Seite. Das Grundelement hat die Länge L, die Breite B und die Dicke h₁. Der Abstand der Durchbrüche voneinander beträgt a und der Abstand der Durchbrüche zu den äußeren Begrenzungen a/2.
  • Figur 2 zeigt einen Schnitt durch das Grundelement an der Stelle der Durchbrüche.
  • Figur 3 zeigt einen Schnitt durch zwei spiegelbildlich an den offenen Flächen aneinandergeschweißte oder geklebte Grundelemente l, lʹ an der Stelle der Durchbrüche.
The invention is explained in more detail by the drawing.
  • Figure l shows the basic element in the perspective with eight square openings and in the view from the closed side. The basic element has the length L, the width B and the thickness h 1. The distance between the openings is a and the distance between the openings and the outer boundaries is a / 2.
  • Figure 2 shows a section through the basic element at the location of the openings.
  • Figure 3 shows a section through two mirror-image welded or glued basic elements l, lʹ on the open surfaces at the location of the openings.

Wie man erkennt, können erfindungsgemäß gestaltete Grund­elemente durch Zusammenfügen ihrer offenen Flächen aneinan­der auf die folgende Art und Weise zu großflächigen Platten der unterschiedlichsten Gestalt zusammengefügt werden:

  • 1. spiegelbildlich
  • 2. spiegelbildlich mit Versatz
  • 3. spiegelbildlich mit Versatz und Drehung im rechten Winkel.
As can be seen, basic elements designed according to the invention can be joined together by joining their open surfaces to one another in the following manner to form large-area slabs of the most varied shapes:
  • 1. mirror image
  • 2. mirror image with offset
  • 3. mirror image with offset and rotation at right angles.

Diese Platten können mittels quadratischer bzw. runder Achsen oder mittels spezieller Verbindungselemente miteinan­der verbaut werden.

  • Figur 4 zeigt zwei Grundelemente l, lʹ, welche mit ihren offenen Seiten spiegelbildlich zusammengefügt sind. Diese Grundelemente haben 4 × 2 = 8 Durch­brüche. Da der quadratische Durchbruch das Maß a × a hat, errechnet sich die Länge L des Grund­elements wie folgt:

    4 × Durchbrüche von der Kantenlänge a = 4a

    + 3 × Abstand zwischen den Durchbrüchen vom Betrag a = 3a

    + 2 × Abstand zu den äußeren Begrenzungen vom Betrag a/2 = a,

    Länge l des Grundelementes mit 8 Durchbrüchen somit = 8a.

    Die Breite b des Grundelementes errechnet sich folgendermaßen:

    2 × Durchbrüche vom Maße a = 2a

    + l × Abstand zwischen den Durchbrüchen vom Betrag a = la

    + 2 × Abstand zu den äußeren Begrenzungen vom Betrag a/2 = la,

    Breite b des Grundelementes mit 8 Durchbrüchen somit 4a.

    Bei einer Dicke h₁ des Grundelementes von a/2 betragen somit die Abmessungen eines Grundelementes mit 4 × 2 = 8 Durchbrüchen L × b × h₁ = 8a × 4a × a/2.

    Fügt man zwei Grundelemente zu einer Platte mit 8 Durchbrüchen zusammen (s. Figur 4), so hat die Platte die Abmessungen 8a × 4a × a.
  • Figur 5 zeigt eine Platte mit 4 × 4 = l6 Durchbrüchen, zusammengefügt aus vier gleichartigen Grundelemen­ten l, lʹ, lʺ, l‴.
    Diese Platte hat dann die Abmessungen 8a × 8a × a.
  • Figur 6 zeigt zwei Grundelemente 2, 2ʹ, welche mit ihren offenen Seiten spiegelbildlich zusammengefügt sind. Diese Grundelemente haben 6 × 3 = l8 Durch­brüche.

    Da die quadratischen Durchbrüche das Maß a × a haben, ergeben sich für die aus den Grundelemen­ten 2, 2ʹ zusammengefügte Platte die Abmessungen l2a × 6a × a.
  • Figur 7 zeigt eine Platte mit 6 × 6 = 36 Durchbrüchen, zusammengefügt aus 4 gleichartigen Grundelementen 2, 2ʹ, 2ʺ, 2‴.
    Diese Platte hat dann die Abmessungen l2a × l2a × a.
These panels can be installed together using square or round axes or using special connecting elements.
  • Figure 4 shows two basic elements l, lʹ, which are joined with their open sides in mirror image. These basic elements have 4 × 2 = 8 breakthroughs. Since the square opening has the dimension a × a, the length L of the basic element is calculated as follows:

    4 × breakthroughs with the edge length a = 4a

    + 3 × distance between the breakthroughs of the amount a = 3a

    + 2 × distance to the outer limits of the amount a / 2 = a,

    Length l of the basic element with 8 openings = 8a.

    The width b of the basic element is calculated as follows:

    2 × openings of dimension a = 2a

    + l × distance between the breakthroughs of the amount a = la

    + 2 × distance to the outer limits of the amount a / 2 = la,

    Width b of the basic element with 8 openings thus 4a.

    With a thickness h 1 of the basic element of a / 2, the dimensions of a basic element with 4 × 2 = 8 openings are L × b × h 1 = 8a × 4a × a / 2.

    If two basic elements are combined to form a plate with 8 openings (see FIG. 4), the plate has the dimensions 8a × 4a × a.
  • Figure 5 shows a plate with 4 × 4 = l6 openings, assembled from four similar basic elements l, lʹ, lʺ, l ‴.
    This plate then has the dimensions 8a × 8a × a.
  • Figure 6 shows two basic elements 2, 2ʹ, which are joined together with their open sides in mirror image. These basic elements have 6 × 3 = 18 breakthroughs.

    Since the square openings have the dimension a × a, the dimensions l2a × 6a × a result for the plate assembled from the basic elements 2, 2ʹ.
  • Figure 7 shows a plate with 6 × 6 = 36 openings, assembled from 4 similar basic elements 2, 2ʹ, 2ʺ, 2 ‴.
    This plate then has the dimensions l2a × l2a × a.

Erfindungswesentlich ist, daß die Längen des Grundelements immer ein ganzes Vielfaches, jedoch mindestens das zweifache der Breiten des Grundelementes sind.It is essential to the invention that the lengths of the basic element are always a whole multiple, but at least twice the widths of the basic element.

Zum Beispiel: L : b = 2 : l

und daß bei Drehung der Grundelemente untereinander im rechten Winkel oder bei Versatz die Durchbrüche deckungs­gleich bei bündiger Außenkontur der zusammengefügten Platten sind.For example: L: b = 2: l

and that when the basic elements are rotated at right angles to one another or in the event of an offset, the openings are congruent with a flush outer contour of the assembled plates.

Diese Deckungsgleichheit der Durchbrüche wird erfindungsge­mäß dadurch erreicht, daß der Abstand a der Durchbrüche gleich der Seitenlänge des Querschnittes a × a ist und daß der Abstand der Durchbrüche zu den äußeren Begrenzungen des Grundelementes gleich a/2 ist.This congruence of the openings is achieved according to the invention in that the distance a of the openings is equal to the side length of the cross section a × a and that the distance of the openings to the outer boundaries of the base element is equal to a / 2.

Somit ist es immer möglich, beliebig große Platten aus gleich großen Grundelementen zusammenzufügen; bei einem Längen/Breiten-Verhältnis des Grundelementes von 2 : l.It is therefore always possible to join panels of any size from basic elements of the same size; with a length / width ratio of the basic element of 2: 1.

Die in den Figuren l6 bis 22 gezeigten Platten lassen sich z.B. sinnvoll kombinieren mit Steckbausteinen nach DE-PS 2l 6l 9l3.The plates shown in Figures 16 to 22 can e.g. sensibly combine with plug-in modules according to DE-PS 2l 6l 9l3.

Unter Berücksichtigung gewisser Verhältnisse zwischen den Abmessungen und den Durchbrüchen ergeben sich optimale Kombinationsmöglichkeiten des Grundelementes unter Erzielung unterschiedlich großer Platten, und gleichzeitig wird sichergestellt, daß die daraus entstandenen Platten mitein­ander verbaut werden können.Taking into account certain relationships between the dimensions and the openings, there are optimal possible combinations of the basic element to achieve panels of different sizes, and at the same time it is ensured that the resulting panels can be installed together.

Dies wird erfindungsgemäß dadurch erreicht, daß der Abstand der Durchbrüche untereinander (a) doppelt so groß ist wie der Abstand a/2 zu den äußeren Begrenzungen des Grundelemen­tes (s. Figur l). Die zusätzliche Angabe, daß der quadra­tische Querschnitt der Durchbrüche die Seitenlänge a hat, ist hierbei keine zwingende Voraussetzung.This is achieved according to the invention in that the distance between the openings (a) is twice as large as the distance a / 2 from the outer limits of the basic element (see FIG. 1). The additional information that the square cross section of the openings has the side length a is not a mandatory requirement.

Grundsätzlich gelten die gleichen Vorteile und Möglichkei­ten, wenn die Durchbrüche kreisförmig sind oder eine andere beliebige Form haben (z.B. sternförmig sind mit 4 oder 8 Strahlen).Basically, the same advantages and options apply if the openings are circular or have any other shape (e.g. star-shaped with 4 or 8 beams).
