Description

Die Erfindung betrifft ein Sicherungselementfür Bauteile eines Spielbaukastens, die mittels hinterschnittenen Nuten und in diese passenden Zapfen miteinander verbindbar sind.The invention relates to a securing element for components of a play kit, which can be connected to one another by means of undercut grooves and pins that fit into them.

Bei einem bekannten Spielbaukasten, dessen Bauteile über hinterschnittene Nuten und hinterschnittene Leisten bzw. Vorsprünge miteinander verbindbarsind, sind die Toleranzen dieser Verbin - dungsmittel so gewählt, dass ein Schiebesitz erreicht ist, dessen Haftreibung die Aufnahme kleiner, in Längsrichtung der Nuten gerichteter Kräfte erlaubt. Bei grösseren Kräften reicht allerdings die Haftwirkung allein nicht mehr aus. Ferner werden bei diesem bekannten Spielbaukasten auch bspw. aus Aluminium hergestellte Strangpressprofile verwendet, deren Längsnuten aufgrund des Herstellverfahrens grössere Toleranzen aufweisen. Damit sind für stabile Querverbindungen umständliche Verriegelungen und Verstrebungen erforderlich, die zum einen den Modellaufbau erschweren und zum anderen aus Platzmangel nicht immer anbringbar sind (z.B. DE-U Nr. 7416917).In a known toy construction kit, the components of which can be connected to one another via undercut grooves and undercut strips or projections, the tolerances of these connecting means are selected such that a sliding seat is achieved, the static friction of which allows the absorption of small forces directed in the longitudinal direction of the grooves. With larger forces, however, the adhesive effect alone is no longer sufficient. Furthermore, extruded profiles made of aluminum, for example, are used in this known toy construction kit, the longitudinal grooves of which have greater tolerances due to the manufacturing process. This means that complicated locks and struts are required for stable cross connections, which on the one hand complicate the model construction and on the other hand are not always attachable due to lack of space (e.g. DE-U No. 7416917).

Der Erfindung liegt daher die Aufgabe zugrunde, eine Möglichkeit zu schaffen, bei Verbindungen die in Längsrichtung der Nuten gerichteten Kräfte aufzunehmen.The invention is therefore based on the object of creating a possibility of absorbing the forces directed in the longitudinal direction of the grooves in connections.

Erfindungsgemäss wird dies dadurch erreicht, dass das Sicherungselement aus zwei Teilen besteht, wobei jedes Teil mit einer in die Nutder Bauteile eingreifenden, das Nutprofil teilweise ausfüllenden und in Längsrichtung keilförmigen Leiste versehen ist, und dass die beiden Teife mit ihren Leisten durch Zusammenschieben in der Nut der Bauteile festsetzbar sind.This is achieved according to the invention in that the securing element consists of two parts, each part being provided with a bar which engages in the groove of the components, partially filling the groove profile and wedge-shaped in the longitudinal direction, and in that the two bars with their bars are pushed together in the groove the components can be fixed.

Zum Festsetzen werden beide Teile des Sicherungselementes in die hinterschnittene Nute des Bauteileseingefegt und die Leisten der beiden Teile mit ihren schwächeren Stirnseiten zueinander gekehrt gegeneinander verschoben. Durch die Keilform der Leisten entsteht dabei eine Verspannung beides Teile in der hinterschnittenen Nut des Bauteiles, so dass ein fester Klemmsitz erreicht wird. Das Sicherungselement dient nunmehr als Anschlag für einen Baustein, der mit einem Verbindungszapfen versehen im leichten Schiebesitz in die Längsnut des Bauteiles einschiebbar ist. Mit einem weiteren, hinter diesem Baustein festgesetzten Sicherungselement ist dieser nach allen Richtungen hin gegen Verschieben gesichert. Es können somit genaue, auch bei hohen Kräften festbleibende Abstände eingestellt werden.For fixing, both parts of the securing element are inserted into the undercut groove of the component and the strips of the two parts, with their weaker end faces, are shifted towards each other. Due to the wedge shape of the strips, both parts are braced in the undercut groove of the component, so that a firm clamp fit is achieved. The securing element now serves as a stop for a module that can be inserted into the longitudinal groove of the component in a light sliding fit provided with a connecting pin. With another securing element fixed behind this module, it is secured against displacement in all directions. It is thus possible to set precise distances that remain constant even with high forces.

In einer weiteren Ausgestaltung der Erfindung kann die eine Längsseite der Leister hinterschnitten und die ander Längsseite plan ausgebildet sein. Die planen Längsseiten der Leisten bilden die Gleitflächen, während durch die hinterschnittenen Längsseiten der Leisten die vollständige Ausfüllung des Nutprofils erfolgt. Beide Leisten ergänzen sich somit zu einem beidseitig hinterschnittenen Verbindungsmittel, so dass neben der Verklemmung auch eine gegen Abheben gesicherte Formschlussverbindung entsteht.In a further embodiment of the invention, the one long side of the strips can be undercut and the other long side can be flat. The flat long sides of the strips form the sliding surfaces, while the undercut long sides of the strips completely fill the groove profile. Both strips thus complement each other to form an undercut connecting means on both sides, so that, in addition to the jamming, a form-fitting connection secured against lifting is also created.

In einer weiteren Gestaltung der Erfindung kann die Leiste an ihrer stärksten Stelle etwas schmäler sein als die lichte Weite der engsten Stelle der hinterschnittenen Nut des Bauteiles. Diese Gestaltung ermöglicht es, die beiden Teile des Sicherungselementes von der Aussenseite her in die hinterschnittene Nut des Bauteiles einzusetzen. Das zeitraubende Einschieben von der Frontseite der Nut her insbesondere bei sehr langen Bauteilen ist somit nicht erforderlich. Das Sicherungselement kann ferner auch nachträglich zwischen zwei im Abstand zueinander bereits angeordnete Bausteine eingesetzt werden.In a further embodiment of the invention, the strip at its strongest point can be somewhat narrower than the inside width of the narrowest point of the undercut groove of the component. This design makes it possible to insert the two parts of the securing element from the outside into the undercut groove of the component. The time-consuming insertion from the front of the groove, particularly in the case of very long components, is therefore not necessary. The securing element can also be retrofitted between two blocks that are already arranged at a distance from one another.

In einer weiten Ergänzung der Erfindung können die Teile des Sicherungselementes eine an der Aussenfläche der Bauteile aufliegende Griffplatte aufweisen. Die als Einschiebbegrenzung dienende Platte erleichtert durch die Auflage auf den Bauteilen die Handhabung des Sicherungselementes.In a wide addition to the invention, the parts of the securing element can have a grip plate resting on the outer surface of the components. The plate, which serves as an insertion limitation, facilitates handling of the securing element due to the support on the components.

Schliesslich kann in einer weiteren Gestaltung der Erfindung ein Teil des Sicherungselementes als Winkel ausgebildet sein, wobei jeder Schenkel des Winkels mit einer Leiste versehen ist. Durch diese besondere Gestaltung des Sicherungselementes können auch stirnseitige Verbindungen zweier Bauteile gesichert und zusätzlich die Winkelstellung abgestützt werden. Es können somit sehr stabile Rahmenkonstruktionen bspw. für Spielfahrzeuge hergestellt werden.Finally, in a further embodiment of the invention, part of the securing element can be designed as an angle, each leg of the angle being provided with a strip. This special design of the securing element also enables end connections of two components to be secured and the angular position to be additionally supported. Very stable frame constructions, for example for toy vehicles, can thus be produced.

In derZeichnung sind Ausführungsbeispiele der Erfindung dargestellt. Es zeigen:

  • Fig. das aus zwei Teilen bestehende und in der Nut eines Bauteifes eingesetzte Sicherungselement,
  • Fig. 2 die Anendungsmöglichkeiten des Sicherungselementes.
Exemplary embodiments of the invention are shown in the drawing. Show it:
  • 2 is a securing element consisting of two parts and inserted in the groove of a component,
  • Fig. 2 shows the possible uses of the securing element.

In einer der vier hinterschnittenen Längsnuten 1 des aus einem rohrförmigen Strangpressprofil bestehenden Bauteiles 2 sind die beiden das Sicherungselement 3 bildenden Teile 3a, 3b derart eingesetzt, dass die Leisten 4 vorfständig von der Nut 1 aufgenommen sind. Das Profil der Leiste 4 füllt nurteilweise das Nutprofil aus und ist zusätzlich in Längsrichtung keilförmig ausgebildet. Als Einschiebbegrenzung einerseits und zur besseren Handhabung andererseits sind die Teile 3a, 3b des Sicherungselementes mit einer an der Aussenfläehe der Bauteile 2 aufliegenden Platte 5 versehen, deren Aussenfläche geriffelt sein kann.In one of the four undercut longitudinal grooves 1 of the component 2 consisting of a tubular extruded profile, the two parts 3a, 3b forming the securing element 3 are inserted such that the strips 4 are received by the groove 1. The profile of the strip 4 only partially fills the groove profile and is additionally wedge-shaped in the longitudinal direction. As a slide-in limitation on the one hand and for better handling on the other hand, the parts 3a, 3b of the securing element are provided with a plate 5 resting on the outer surface of the components 2, the outer surface of which can be corrugated.

Die sich gegenüberstehenden und als Gleitfläehe dienenden planen Längsseiten 6 der Leisten 4 der beiden Teile weisen in ihrer Längsrichtung eine Verjüngung von ca. 2 Grad auf. Die Leisten 4 sind doppelt so lang als die Platten 5, so dass beim Zusammenschieben der Platten 5 die Leisten 4 innerhalb der Platten zur Überdeckung kommen.The opposing and serving as a sliding surface long sides 6 of the strips 4 of the two parts have a taper of about 2 degrees in their longitudinal direction. The strips 4 are twice as long as the plates 5, so that when the plates 5 are pushed together, the strips 4 overlap within the plates.

Die voneinander abgekehrten Längsseiten 7 der Leisten 4 sind hinterschnitten. Beim Zusammenschieben ergänzen sich damit die beiden Leisten 4 zu einem hinterschnittenen Verbindungsmittel, dessen Aussenmass gegenüber dem Profil der Nut 1 beim Zusammenschieben um ca. 15% vergrösserbar ist. Dadurch kann eine starke Verklemmung erzielt werden, so dass das Sicherungselement 3 an jeder gewünschten Stelle der Nut 1 des Bauteiles 2 unverrückbar festgesetzt werden kann. Um das Einsetzen der Teile 3a, 3b in die Nut von aussen her durchführen zu können, ist die stärkste Stelle der einzelnen Leiste 4 etwas schmäler als die lichte Weite der engsten Stelle der hinterschnittenen Nut 1 des Bauteiles. Die Addition dieser stärksten Stelle mit der schwächsten Stelle der anderen Leiste ergibt jedoch das zur Verklemmung notwendige Übermass gegenüber dem Nutprofil.The longitudinal sides 7 of the strips 4 facing away from one another are undercut. When pushed together, the two strips 4 thus complement one another to form an undercut connecting means, the external dimension of which can be enlarged by approximately 15% compared to the profile of the groove 1 when pushed together. As a result, a strong jamming can be achieved, so that the securing element 3 can be immovably fixed at any desired point in the groove 1 of the component 2. Around to be able to insert the parts 3a, 3b into the groove from the outside, the strongest point of the individual bar 4 is somewhat narrower than the inside width of the narrowest point of the undercut groove 1 of the component. The addition of this strongest point with the weakest point of the other bar results in the excess of the groove profile required for jamming.

Fig. 2 zeigt Anwendungsmöglichkeiten des erfindungsgemässen Sicherungselementes 3. Für die Eckverbindung wird ein Sicherungselement verwendet, bei dem ein Teil des Sicherungselementes 3' als Winkel ausgebildet ist und jeder Schenkel des Winkels eine Leiste 4 aufweist. Zur Verklemmung der beiden die Eckverbindung bildenden Bauteile 2 wird auf jeden Schenkel des Winkels ein weiteres Teil 3b aufgeschoben, so dass durch die sich jeweils überlappenden Leisten 4 die Verbindung zwischen Sicherungselement 3' und Bauteil 2 hergestellt wird. In die Längsnut 1 des einen Bauteiles 2 ist mit leichtem Schiebesitz ein mit einem hinterschnittenen Verbindungszapfen 8 ausgestatteter Baustein 9 bis zur Anlage an dem Winkel-Sicherungselement 3' eingeschoben. Zu dessen Festsetzung wird dann hinter diesen Baustein 9 ein weiteres Sicherungselement 3 verklemmt. Damit ergibt sich eine genaue, auch hohen Kräften standhaltende Abstandsfixierung.2 shows possible applications of the securing element 3 according to the invention. A securing element is used for the corner connection, in which part of the securing element 3 'is designed as an angle and each leg of the angle has a strip 4. To clamp the two components 2 forming the corner connection, a further part 3b is pushed onto each leg of the angle, so that the connection between the securing element 3 'and component 2 is produced by the overlapping strips 4 in each case. A module 9 equipped with an undercut connecting pin 8 is inserted into the longitudinal groove 1 of one component 2 with a slight sliding fit until it rests on the angle securing element 3 '. To fix it, a further securing element 3 is then clamped behind this module 9. This results in an accurate, even withstand high forces distance fixation.
