Description

Knickschutzvorrichtung für Schlauchleitungen Beschreibung : ( siehe Darstellung ) Schlauchleitungen, die mit einer Anschluss-Armatur fest verbunden sind, unterliegen oft während des Einsatzes durch Einbauverhältnisse oder Arbeitsbewegungen bedingten starken Knickbeanspruchungen im Bereich kurz hinter der Anschluss-Armatur. Dadurch wird der Aussenmantel der Schläuche ( Metallgewebe, Textilgewebe oder Gummi ) durch die Kanten der Armatur abgescheuert und die Schläuche nach kurzer Zeit unbrauchbar. Ferner wird die Verbindung zwischen Schlauchmaterial und Armatur durch starke Biegebelastung beträchtlich geschwächt.Kink protection device for hose lines Description: (see Illustration) Hose lines that are firmly connected to a connection fitting are often subject to installation conditions or work movements during use Caused strong buckling loads in the area just behind the connection fitting. This creates the outer jacket of the hoses (metal mesh, textile mesh or rubber ) rubbed off by the edges of the fitting and the hoses become unusable after a short time. In addition, the connection between the hose material and the fitting is caused by strong bending loads considerably weakened.

Der Erfindungsgegenstand soll diesem Übel abhelfen und ist als Knickschutzrohr (4) gekennzeichnet. Es handelt sich dabei um ein zyl. Rohr, dessen Innendurchmesser passend über den Aussendurchmesser der Schlauchfassung (2) geschoben wird. Das zyl. Ende (5) des Knickschutzrohres (4) wird mechanisch in die Ringnut zwischen Anschlusskopf (1) und Schlauchfassung (2) eingebördelt und dadurch mit der Armatur verbunden.The subject of the invention is intended to remedy this evil and is used as a kink protection tube (4) marked. It is a cyl. Pipe, its inside diameter is pushed over the outer diameter of the hose holder (2). The cyl. The end (5) of the anti-kink tube (4) is mechanically inserted into the annular groove between the connection head (1) and hose socket (2) crimped and thereby connected to the fitting.

Das trichterförmige Ende (7) des Knickschutzrohres verhindert eine Beschädigung des Schlauchmaterials (3) am Armaturenausgang (6) und leitet die gegebene Biegebelastung in das anschliessende flexibele Schlauchmaterial ein.The funnel-shaped end (7) of the anti-kink tube prevents a Damage to the hose material (3) at the fitting outlet (6) and leads the given Bending load in the subsequent flexible hose material.

A N S P R Ü C H E 1.) Anspruch 1 wird dadurch gekennzeichnet, dass durch die Knick-Schutzvorrichtung erstmalig ein starkes Abknicken des Schlauchmaterials direkt hinter der Anschluss-Armatur vermieden wird.A N S P R Ü C H E 1.) Claim 1 is characterized in that Due to the kink protection device, a strong kinking of the hose material for the first time directly behind the connection fitting is avoided.

2.) Anspruch 2 wird dadurch gekennzeichnet, dass das. Knickschutzrohr durch Bördelung mit der Armatur verbunden ist.2.) Claim 2 is characterized in that the. Anti-kink tube is connected to the valve by flanging.

Claims (1)

3.) Anspruch 3 wird dadurch gekennzeichnet, dass das Knickschutzrohr mit einem trichterförmigen Ausgang versehen ist und damit Beschädigungen des Schlauchmantels vermieden werden.3.) Claim 3 is characterized in that the anti-kink tube is provided with a funnel-shaped exit and thus damage to the hose jacket be avoided. LeerseiteBlank page
