Abstract

The invention relates to a tube clamp for clamping a tube to a pipe, characterised by a clamp fitting (1) which has a U-shaped profile and comprises projections or openings (1a) in which a claw (2) can be inserted. Said claw can achieve the required clamping force by means of tongs.

Description

Beschreibung description

Schlauchklemme mit KralleHose clamp with claw

Die Erfindung betrifft eine leicht montierbare Schlauchklemme aus Band, in Regellänge für die Anpassung an den jeweiligen Schlauchdurchmesser. Vorgebogene Klemmen, vorzugsweise für kleinere Rohrdurchmesser.The invention relates to an easily mountable hose clamp made of tape, in the standard length for adaptation to the respective hose diameter. Pre-bent clamps, preferably for smaller pipe diameters.

Es sind Schlauchklemmen bekannt, die den genannten Zweck jedoch nur eingeschränkt erfüllen. So wird bspw. ein Flaσhband benutzt, welches folgende Nachteile hat: Im geschlossenen Zustand steht die Kralle in der Schlauchklemme vor, welches leicht die Verletzung des Schlauches bewirkt.Hose clamps are known, but they only fulfill the stated purpose to a limited extent. For example, a flat band is used, which has the following disadvantages: in the closed state, the claw protrudes in the hose clamp, which easily causes the hose to be injured.

Wegen des ebenen Bandes ist ein Einfügen eines unverlierbaren lήnenringes, wie in Fig. 1 dargestellt, nicht möglich. Das Einhängen der Kralle ist schwierig.Because of the flat band, it is not possible to insert an captive inner ring, as shown in FIG. 1. Hooking the claw is difficult.

Diese Probleme sollen mit der erfindungsgemäßen Schlauchklemme gelöst werden.These problems are to be solved with the hose clamp according to the invention.

Die Erfindung ist anhand der Fig, 1 bis 5 dargestellt und erläutert.The invention is illustrated and explained with reference to FIGS. 1 to 5.

Die Kralle, zu sehen in Fig. 1, ist durch optimierte Formgebung (nach innen gewölbt) in der Lage, eine Vorspannung zu erzeugen und legt sich bei der Montage gegen innen an, wodurch die Klemmkraft noch verstärkt wird. Eine spezielle Zange ist nicht erforderlich. Die Flächenpressung auf das Rohr wird durch das Profilieren des Bandes erheblich vergrößert. Das Ansetzen der Kralle wird erheblich erleichtert. Das Klemmband 1, zu sehen in Fig. 1, macht das Einlegen eines Innenrings 3 möglich. Der flache Innenring 3 kann auf den Innendurchmesser gebogen und unverlierbar eingelegt werden. The claw, shown in Fig. 1, is able to generate a pre-tension due to optimized shape (arched inwards) and lies against the inside during assembly, which further increases the clamping force. Special pliers are not required. The surface pressure on the pipe is considerably increased by profiling the strip. Attaching the claw is made considerably easier. The clamping band 1, shown in Fig. 1, makes it possible to insert an inner ring 3. The flat inner ring 3 can be bent to the inner diameter and inserted captively.
