Abstract

The spring clip (1) is made from spring wire and has a rounded end (2) to match the dia. of the exhaust pipe (3). The arms of the clip are bent to roughly S shapes with the middle sections (4, 5) bulging outwards. The ends of the arms (12, 13) are bent outwards in opposite directions. The end sections fit into pockets (14, 15) formed in a metal strip attached to the undersurface of the vehicle. The bulging middle sections provide a convenient grip for pressing the two arms together for installation or removal. The clip may be made of stainless steel or galvanised carbon steel or even suitable heat-resisting plastic.

Description

"lia lt eklammer""lia lt eklammer"

Die Erfindung betrifft eine Ilalteklammer aus federndem Material, beispielsweise aus Federstahldraht, zum nachgiebigen und lösbaren Festklemmen von Bauteilen mit vorzugsweise runder Querschnittsform, z.B. Auspuffleitungen von Kraftfahrzeugen.The invention relates to an Ilalteklammer made of resilient material, for example made of spring steel wire, for resilient and releasable clamping of Components with a preferably round cross-sectional shape, e.g. exhaust lines of motor vehicles.

Bei einer bereits bekannten Ausführung (DT-PS l 143 554) ist z. B. vorgeschlagen worden, mit einer Schelle eine Leitung einzuklemmen, die beiden Enden der Schlaufe durch ein Loch in einer Unterlage durchzustecken und sie zum Festhalten der Verbindung hakenförmig umzubiegen. Nachteilig ist hierbei, daß die Klemmverbindung nicht nachgiebig genug, vorallem nicht schnell und ohne weiteres leicht lösbar ist.In an already known version (DT-PS l 143 554) z. B. it has been proposed to clamp a line with a clamp, the two ends put the loop through a hole in a pad and hold it in place to bend the connection in the shape of a hook. The disadvantage here is that the clamp connection not flexible enough, especially not quickly and easily solved.

Der Erfindung lag daher die Aufgabe zugrunde, die vorstehenden Nachteile zu vermeiden und mit einfachen Mitteln eine Ilalteklammer zu schaffen, die kostengjinstig aus einem Stück hergestellt und die zum nachgiebigen und schnell lösbaren Festklemmen von Bauteilen geeignet ist.The invention was therefore based on the object of the above disadvantages to avoid and to create an inexpensive bracket with simple means made from one piece and the flexible and quickly releasable clamping of components is suitable.

Dies geschieht nach der Erfindung dadurch, daß die Ilalteklammer die Form einer Haarnadel aufweist, deren bogenförmiger Scheitelbereich als Klemmteil zur Aufnahme des zu haltenden Bauteils ausgebildet ist, und daß die Schenkel der Klammer etwa in ihrem mittleren Bereich nach außen ausgebuchtet und die anschließenden freien Enden der Schenkel über einen Teil ihrer Lange nahezu rechtwinklig abgebogen sind.This is done according to the invention in that the Ilalteklammer the Has the shape of a hairpin, the arcuate apex area as a clamping part to hold the Component is formed, and that the legs of the clip bulge outwards approximately in their middle area and the subsequent free ends of the legs almost over part of their length are bent at right angles.

In Ausgestaltung der Erfindung sind die Ausbuchtungen der Schenkel henkelförmig ausgebildet, wobei die Übergänge vom Klemmteil zu den Ausbuchtungen etwa S-förmig und die Übergänge von den Ausbuchtungen zu den abgebogenen freien Enden der Schenkel abgerundet sind.In an embodiment of the invention, the bulges are the legs designed as a handle, the transitions from the clamping part to the bulges approximately S-shaped and the transitions from the bulges to the bent free ones Ends of the legs are rounded.

In vorteilhafter Ausgestaltung der Erfindung sind die abgebogenen freien Enden der Schenkel in zwei fahrzeugfeste, taschenförmige Halterungen einhängbar.In an advantageous embodiment of the invention, the bent free ends of the legs can be hung in two pocket-shaped brackets fixed to the vehicle.

In der Zeichnung ist eine Ausführungsform der Erfindung beispielsweise dargestellt. Sie zeigt eine aus Federstahldraht hergestellte Jialteklammer 1, deren bogenförmiger Scheitelbereich als Klemmteil 2 zur Aufnahme eines Bauteils, und zwar einer Auspuffleitung 3, ausgebildet ist. Das Material der Halteklammer 1 kann zur Vermeidung von Korrosion entsprechend legiert oder auch galvanisch behandelt sein. Unter Umständen ist es auch denkbar, daß zwischen die Auspuffleitung 3 und das sie umfassende Klemmteil 2 eine hitzebeständige Manschette gelegt ist.In the drawing, an embodiment of the invention is for example shown. It shows a Jialte clip 1 made of spring steel wire, whose arcuate apex area as a clamping part 2 for receiving a component, namely an exhaust pipe 3 is formed. The material of the retaining clip 1 can be used for To avoid corrosion, be alloyed or galvanically treated accordingly. Under certain circumstances, it is also conceivable that between the exhaust line 3 and that they comprehensive clamping part 2 is placed a heat-resistant sleeve.

Die beiden Schenkel der Jialteklammer 1 zeigen im mittleren Bereich henkelförmige Ausbuchtungen 4 und 5, wobei die Übergänge 6 und 7 etwa S-förmig und die Übergänge 8, 9, 10 und 11 entsprechend abgerundet ausgeführt sind. Die anschließenden rechtwinklig abgebogenen freien Enden 12 und 13 der Halteklammer 1 sind in zwei taschenförmige Halterungen 14 und 15 eingehängt, die sich an einem fahrzeugfesten Bauteil 16 befinden.The two legs of the Jialte clamp 1 point in the middle area handle-shaped bulges 4 and 5, the transitions 6 and 7 approximately S-shaped and the transitions 8, 9, 10 and 11 are rounded accordingly. The subsequent At right angles bent free ends 12 and 13 of the retaining clip 1 are in two pocket-shaped brackets 14 and 15 hooked, which are fixed to a vehicle Component 16 are located.

Die Ausbuchtungen und die Übergänge der erfindungsgemäßen Halteklammer 1 dienen als Dehnschlaufen mit federnder Nachgiebigkeit in Querrichtung zu den festgeklemmten Bauteilen, wobei die freien Enden 12 und 13 unter Ausnutzung einer etwa vorgegebenen oder durch das festgeklemmte Bauteil entstehenden Aufspreizwirkung in die Halterungen 14 und 15 gedrückt werden.The bulges and the transitions of the retaining clip according to the invention 1 serve as stretch loops with elastic resilience in the transverse direction to the clamped Components, the free ends 12 and 13 taking advantage of an approximately predetermined or the spreading effect created by the clamped component in the brackets 14 and 15 are pressed.

Damit wird erreicht, daß das festgeklemmte Bauteil verschiebefest und schwingungsarm gehalten wird.This ensures that the clamped component cannot move and is kept low-vibration.

Die Ausführungsform der Halteklammer begünstigt eine gute Wärmeabfuhr durch den Fahrtwind.The embodiment of the retaining clip promotes good heat dissipation by the wind.

Abschließend sei noch erwähnt, daß durch Form und Anordnung der Halteklammer, die auch aus einem anderen temperaturbeständigen Material, z.B. Kunststoff oder Kautschuk, hergestellt sein kann, eine einfache und schnelle Montage bzw. Demontage erreichbar ist.Finally it should be mentioned that the shape and arrangement of the retaining clip, which are also made of another temperature-resistant material, e.g. plastic or Rubber, can be produced, a simple and quick assembly and disassembly is attainable.
