Description
Faltenbalg od.dgl. Die bisher bekannten, einstückig hergestellten Faltenbälge aus Gummi oder thermoplastischem Kunststoff haben den Nachteil, daß die Falten bei starker Streckung des Balges leicht einknicken und beim anschließenden Zusammendrücken vielfach ihre Ausgangslage nicht wieder einnehmen.Bellows or the like. The previously known, manufactured in one piece Bellows made of rubber or thermoplastic have the disadvantage that the folds bend slightly when the bellows is stretched a lot and when the bellows is then stretched Squeezing them often do not resume their original position.
Gemäß vorliegender Erfindung wird dieser Nachteil dadurch behoben, daß der Faltenbalg aus einer Anzahl mit Gummi oder thermoplastischem Kunststoff beschichteter Textilgewebescheiben besteht, deren flach aufeinanderliegende Innen- und Außenränder durch Vulkanisier- oder Schweißnähte von mindestens 3 mm Breite miteinander verbunden sind. Die so ausgebildeten Faltenbälge zeichnen sich durch außerordentliche Formstabilität aus.According to the present invention, this disadvantage is eliminated by that the bellows made of a number with rubber or thermoplastic material coated textile fabric disks, the inner surface of which lies flat on top of one another and outer edges by vulcanizing or welding seams at least 3 mm wide are connected to each other. The bellows designed in this way are distinguished by extraordinary dimensional stability.
Es sind zwar schon Faltenbälge aus Textilgewebeteilen bekannt, die an den Innen- und Außenrändern durch Nähte miteinander verbunden sind, jedoch besitzen diese reinen Textilgewebebälge auch keine ausreichende Formstabilität. Außerdem sind diese Textilgewebebälge nicht staub- und wasserdicht.There are already known bellows made of textile fabric parts that are connected to one another by seams on the inner and outer edges, but have these pure textile fabric bellows also insufficient dimensional stability. In addition, these textile fabric bellows are not dustproof and waterproof.
In der Zeichnung ist ein Ausführungsbeispiel der Erfindung dargestellt, und zwar zeigt die Abbildung einen Längsschnitt durch einen nach der Erfindung ausgebildeten Faltenbalg. Dieser Faltenbalg besteht aus einer Anzahl kreisrunder Textilgewebescheiben a, die mit Gummi oder thermoplastischem Kunststoff beschichtet und an den Innen- und Außenrändern durch Vulkanisier- oder Schweißnähte b und c unlösbar miteinander verbunden sind. Diese Nähte b und c haben eine Breite von etwa 3 bis 5 mm. Infolge der Steifheit des Materials und insbesondere der Nähte b und c zeichnen sich die erfindungsgemäßen Bälge durch eine bisher nicht erreichte Formstabilität aus, was für die Praxis von ausschlaggebender Bedeutung ist. Ferner sind die erfindungsgemäßen Bälge absolut dicht.In the drawing, an embodiment of the invention is shown, namely, the figure shows a longitudinal section through one formed according to the invention Bellows. This bellows consists of a number of circular textile fabric disks a, which is coated with rubber or thermoplastic and attached to the interior and outer edges by vulcanizing or welding seams b and c inextricably linked are connected. These seams b and c have a width of about 3 to 5 mm. As a result the stiffness of the material and especially the seams b and c stand out Bellows according to the invention by a previously unachieved dimensional stability from what is of crucial importance in practice. Furthermore, the invention Bellows absolutely tight.
Naturgemäß läßt sich die Erfindung nicht nur bei runden Faltenbälgen verwirklichen; vielmehr können auch beliebig anders profilierte Faltenbälge oder Gleitbahnschützer gemäß der Erfindung ausgebildet sein.Naturally, the invention can be applied not only to round bellows realize; Rather, any other profiled bellows or Slideway guards be designed according to the invention.
