Abstract

The opening through which the first barb (10) of the tension bar is inserted is aligned at right angles to the tension direction (S) of the bar (5). When snapped irreversibly into the abutment the first barb (10) of the tension bar engages round the supporting non-deformable edge of the opening (8) like a rear cut section. The edge area or flap (7) of the opening (8) opposite the support edge in the tension direction can be elastically deformable in order to create the snap closing action. The opening (8) is pref. a gap with two opposite edges of which one forms the supporting edge. USE/ADVANTAGE - Where space restricts, tension bar can now be snapped into abutment through snap force applied perpendicular to tension direction of bar.

Description

Die Erfindung betrifft ein Widerlager nach dem Ober­ begriff des Patentanspruchs 1.The invention relates to an abutment according to the upper Concept of claim 1.

Mit den gattungsgemäßen Spannbügeln können Teile mit­ einander verbunden werden, indem der Spannbügel an dem einen Teil fixiert in einem Widerlager und an dem anderen Teil lösbar angreift.With the generic clamps, parts with can be connected to each other by using the clamp one part fixed in an abutment and on the other part releasably attacks.

Bei einem aus der Praxis bekannten Widerlager wird der Spannbügel mit dem als Widerhaken ausgebildeten einen Ende in eine Öffnung dieses Widerlagers irre­ versibel eingeschnappt. Die Öffnung für das Einführen des einzuschnappenden Spannbügelendes ist dabei so ausgerichtet, daß die Einführung in diese Öffnung so­ wie das Aufbringen der Einschnappkraft in Richtung der Spannkraft erfolgen muß, unter der der Spannbügel im verspannten Zustand steht.In an abutment known from practice the clamp with the barbed one one end into an opening of this abutment snapped versibly. The opening for insertion of the snap-in clamp end is like this aligned that introduction to this opening like that like applying the snap force in the direction the clamping force must be below which the clamping bracket is in a tense state.

In der Praxis gibt es Fälle, in denen ein derartiges Einführen des Spannbügels sowie des Aufbringens der Einschnappkraft in dieser Richtung aus Platzgründen nicht möglich ist. Dies trifft z. B. zu, wenn das Teil, an dem sich das Widerlager befindet, oberhalb der Einführöffnung für den Spannbügel einen Vorsprung besitzt, der das Aufbringen einer Einschnappkraft aus dieser Richtung verhindert.In practice there are cases where such Introduce the clamp and apply the Snap force in this direction for space reasons not possible. This applies e.g. B. to if that The part where the abutment is located above a protrusion of the insertion opening for the clamping bracket possesses the application of a snap-in force prevented this direction.

Hiervon ausgehend beschäftigt sich die Erfindung mit dem Problem, das Widerlager für den Spannbügel so auszubilden, daß der Spannbügel durch eine senkrecht zur Spannrichtung des Spannbügels aufzubringende Ein­ schnappkraft in das Widerlager irreversibel einge­ schnappt werden kann.Proceeding from this, the invention deals with the problem, the abutment for the clamping bracket like this train that the clamping bracket by a vertical to be applied to the clamping direction of the clamping bracket snap force irreversibly inserted into the abutment can be snapped.

Eine Lösung dieses Problems gibt das kennzeichnende Merkmal des Anspruchs 1 an.The characteristic provides a solution to this problem Feature of claim 1.

Zweckmäßige Ausgestaltungen dieser Lösung sind Gegen­ stand der Unteransprüche.Appropriate configurations of this solution are counter stood the subclaims.

Ein Ausführungsbeispiel ist in der Zeichnung darge­ stellt, die zwei durch einen erfindungsgemäß gelager­ ten Spannbügel miteinander verbundene Teile in einer Ansicht zeigt, wobei der Bereich des Widerlagers als Ausschnitt im Schnitt dargestellt ist.An embodiment is shown in the drawing represents the two by a bearing according to the invention parts connected to each other in one View shows the area of the abutment as Section is shown in section.

Durch einen Spannbügelverschluß 1 sind ein erstes Teil 2 und ein zweites Teil 3 lösbar miteinander ver­ bunden. Dabei sind die Spannbügelverschlüsse 1 minde­ stens zweifach auf dem Umfang der zu verbindenden Teile vorgesehen.By a clamp closure 1 , a first part 2 and a second part 3 are releasably connected to one another. The clamp locks 1 are provided at least twice on the circumference of the parts to be connected.

Der Spannbügelverschluß 1 besteht aus einem fest mit dem ersten Teil 2 verbundenen Widerlager 4, einem Spannbügel 5 und einem an dem zweiten Teil 3 ange­ brachten Lagerbock 6.The clamp bracket 1 consists of a fixed to the first part 2 abutment 4 , a clamp 5 and a to the second part 3 brought bracket 6th

In dem Widerlager 4 ist der Spannbügel 5 schwenkbar irreversibel, d. h. nicht wieder ausnehmbar einge­ schnappt. Die einschnappende Wirkung bei der darge­ stellten Ausführungsform wird durch eine elastische Verformbarkeit der Lasche 7 bewirkt, die den von dem zweiten Teil 3 entfernt liegenden Rand der Öffnung 8 des Widerlagers 4 bildet.In the abutment 4 , the clamping bracket 5 is pivoted irreversible, that is, snaps not removable again. The snapping effect in the Darge presented embodiment is caused by an elastic deformability of the tab 7 , which forms the distant edge of the opening 8 of the abutment 4 from the second part 3 .

Der dem Teil 3 zugekehrte Rand der Öffnung 8 wirkt als Stützrand des Widerlagers 4 zur Aufnahme der Spannkraft des Spannbügels 5.The edge of the opening 8 facing the part 3 acts as a supporting edge of the abutment 4 for receiving the clamping force of the clamping bracket 5 .

Insgesamt ist die Öffnung 8 als seitlich offener Spalt ausgebildet. Die Fixierung des Spannbügels 5 in Richtung der Ebene senkrecht zur Zeichenebene bei dem dargestellten Ausführungsbeispiel erfolgt durch Sei­ tenwände 9 des Widerlagers 4.Overall, the opening 8 is designed as a laterally open gap. The fixation of the clamping bracket 5 in the direction of the plane perpendicular to the plane of the drawing in the illustrated embodiment is carried out by ten walls 9 of the abutment 4th

Durch die Öffnung 8 hindurch ist der Widerhaken 10 des Spannbügels in einem solchen Maße eingeschnappt, daß der Spannbügel 5 nicht ungewollt aus dem Widerla­ ger 4 entfernbar ist, d. h. daß er insbesondere nicht ungewollt aus diesem Widerlager herausgleiten kann.Through the opening 8 through the barb 10 of the clamping bracket is snapped to such an extent that the clamping bracket 5 is not accidentally removed from the Widerla ger 4 , that is, in particular, he can not accidentally slide out of this abutment.

Durch die erfindungsgemäße Ausrichtung der den Wider­ haken 10 des Spannbügels 5 aufnehmenden Öffnung 8 des Widerlagers ist ein Einbringen des Spannbügels 5 senkrecht zu dessen Spannrichtung S montierbar. Dabei kann insbesondere die Einschnappkraft in der senk­ recht zu der Spannrichtung S liegenden Montagerich­ tung aufgebracht werden. Dies ist für eine automati­ sche Montage mit einem Montageautomaten sehr wichtig.Due to the inventive orientation of the counter hook 10 of the clamping bracket 5 receiving opening 8 of the abutment, an insertion of the clamping bracket 5 can be mounted perpendicular to the clamping direction S. In this case, the snap-in force can be applied in the direction perpendicular to the clamping direction S assembly direction. This is very important for automatic assembly with an automatic assembly machine.
