Abstract

The clamp is used for fixing two plastics parts of different cross-section to each other, and is bent out of spring steel strip. The bent shape conforms with that of the two parts to be joined. The spring force of the clamp (A) is such that the two plastics parts (B, R) are held together so that no torsional or tipping movement between them is possible. Nevertheless, the parts can expand under the effect of heat, causing them to draw apart and together again, but this in no way detracts from the ability of the clamp to prevent them twisting or tipping.

Description

Beschreibung zuDescription too

Klammer zur Befestigung zweier Kunststoffteile aneinander, deren Querschnitt unterschiedlich ist.Clamp for fastening two plastic parts to one another, their cross-section is different.

Es ist bekannt,daß Kunststoffteile mit Hilfe von Klammern aneinander befestigt werden, es auch beXannt,daß Klammern dazu benutzt werden'Kunststoffteile unterschiedlichen Querschnitts aneinander zu befestigen.It is known that plastic parts are attached to one another with the aid of clips It is also known that brackets are used to attach 'plastic parts to attach different cross-section to each other.

Aufgabe der Erfindung ist es,Kunststoffteile unterschiedlichen Querschnitts so aneinander zu befestigen,daß sich die Kunstsoffteile,deren Querschnitt unterachiedlich ist,in ihrer Längsrichtung aufeinander zu bewegen und voneinander entfernen koennen,ohne daß sich die Querschnitte dadurch gegeneinander versetzen.The object of the invention is to produce plastic parts with different cross-sections to be attached to each other so that the plastic parts differ in their cross-section is able to move towards each other in their longitudinal direction and move away from each other without that the cross-sections are offset against each other.

Insbesondere ist es die Aufgabe der Erfindung,daß die Kunststoffteile,deren Qerschnitt unterschiedlich ist,feste und durch den normalen Gebrauch nicht lösbar miteinander verbunden sind,aber trotzden die Möglichkeit haben,sich aufeinanderzu oder voneinander weg zu bewegen,ohne daß die Befestigung zueinander dadurch an Qualität leidet.In particular, it is the object of the invention that the plastic parts, their Cross section is different, fixed and not detachable through normal use are connected to each other, but still have the opportunity to approach each other or to move away from each other without affecting the quality of the attachment to each other suffers.

Gegenstand der Erfindung ist eine aus federhartem Stahlband gefertigte gebogene Klammer, deren Konturen denen der miteinander zu befestigenden Kunststoffteile angepaßt sind.The subject of the invention is a made of spring-hard steel strip curved bracket, the contours of which are those of the plastic parts to be fastened together are adapted.

Dergestelt,daß die Klammer die Konturen der unterschiedlichen Querschnitte der miteinander zu befestigenden Kunststoffteile umscnließt, dergestalt,daß die Klammer in den Bereichen,in denen die Konturen der beiden miteinander zu befestigenden Kunststoffteile übereinstimmen,eine gleichbleibende Formgebung hat, dergestalt,daß die Klammer in den Bereichen,in denen die Querschnitte der aneinander zu befestigenden Kunststoffteile unterschiedlich sind,zur hälfte eine Anpassung an eines der beiden und zur anderen Hälfte eine Anpassung an das andere der beiden miteinander zu befestigenden Kunststoffteile hat, dergestalt,daß die Anpassung an die unterschiedlichen Querschnitte formschlüssig sind, dergestalt,daß eine Verdrehung oder Verkantung der beiden Kunststoffteile zueinander,deren Querschnitt unterschiedlich ist, nicht möglich ist.Such that the bracket the contours of the different cross-sections of the plastic parts to be fastened together, in such a way that the Brace in the areas where the contours of the two are to be fastened together Plastic parts match, has a consistent shape, such that the bracket in the areas where the cross-sections of the to be fastened together Plastic parts are different, half an adaptation to one of the two and on the other half an adaptation to the other of the two to be fastened together Plastic parts has such that the adaptation to the different cross-sections are form-fitting, such that a twisting or tilting of the two plastic parts each other, whose cross-section is different, is not possible.

Durch die Erfindung wird erreicht'daß Kunststoffteile ,deren Querschnitt unterschiedlich ist,so aneinander befestigt werden können,daß eine Verdrehung oder Verkantung der beiden Funststoffteile zueinander nicht möglich ist.The invention achieves that plastic parts, their cross-section is different, so can be attached to each other that a twist or Canting of the two plastic parts to each other is not possible.

Durch die Erfindung wird ferner erreicht,daß sich die beiden Kunststoffteile,deren Querschnitt unterschiedlich ist,aufeinanderzu oder voneinander weg bewegen können,ohne daß dadurch die Verhinderung der Verdrehung oder Verkantung aufgehoben wird.The invention also ensures that the two plastic parts, their Cross-section is different, can move towards or away from each other without that thereby the prevention of rotation or canting is canceled.

Durch die Erfindung wird insbesondere erreicht,daß Kunststoffteile, deren Wärmeausdehnung eine bestimmts Beweglichkeit in Ausdehnungsrichtung erforder,einen bestimmten Sitz zueinander behalten.The invention achieves in particular that plastic parts, whose thermal expansion requires a certain mobility in the direction of expansion keep a certain seat to each other.

Claims

Fatent claim clip for fastening two plastic parts to one another, the cross-section of which is different.

1. Bracket for attaching two plastic parts to each other, whose Cross-section is different, characterized; they are made of spring-hard steel tape is curved; 2. according to claim 1, characterized in that the shape of the bend is coherent with the shape of two plastic parts to be fastened to one another; 3. according to claim 1 and 2, characterized in that the plastic parts are different Have cross-section and the bracket each half the shapes of the different adapts plastic parts shaped in cross-section; 4. according to claim 1 to 3 thereby characterized in that the spring force of the clamp is sufficient to accommodate the different cross-sections the plastic parts so coherently in their ########## that they twist or tilting of the different plastic parts to one another is excluded is; 5. according to claim 1 to 4, characterized in that aie plastic parts that are different in their cross-section, expand through thermal expansion and thus move towards each other and pull together again, thereby moving away from each other without preventing the twisting or tilting of the two Kunstsofftele is lifted to each other.
