BeschreibungDescription

Für ein Luftkissen mit dehnbaren Mantel: Die mir bekannten Luftkissen werden im Kraftfahrzeugbau eingesetzt, überwiegend im Nutzfahrzeugbau. Der Mantel dieser Luftkissen besteht aus Gummi, daß mit Gewebe verstärkt ist, so daß es nicht dehnbar ist, es dient zur Komprimierung der Luft. Andere Modelle werden im Maschinenbau eingesetzt und dienen als Schwingungsdämpfer.For an air cushion with an elastic cover: The air cushions I know are used in automotive engineering, mainly in commercial vehicle construction. The cover of these air cushions is made of rubber that is reinforced with fabric so that it is not elastic; it is used to compress the air. Other models are used in mechanical engineering and serve as vibration dampers.

Der im Schutzanspruch eins angegebene Erfindung liegt das Problem zu Grunde ein von Gewicht her leichtes Federelement zu entwickeln, daß Vibrationen und Schläge aufnimmt, und je nach Bedarf die Federkraft regulierbar ist Ein für den Fahrradbereich einsetzbares Luftkissen mit diesen Eigenschaften konnte ich auf den Markt nicht entdecken.The invention specified in claim 1 is based on the problem of developing a lightweight spring element that absorbs vibrations and impacts and the spring force can be regulated as required. I could not find an air cushion with these properties that could be used on bicycles on the market.

Dieses Problem wird mit den in Schutzanspruch 1+2 aufgeführten Merkmalen gelöst.This problem is solved with the features listed in claims 1 and 2.

Mit der Erfindung entsteht ein leistungsstarkes Federsystem mit hohem Federkomfort bei geringem Eigengewicht. Die Herstellungskosten müssen im wirtschaftlichen Rahmen sein. Durch Temperaturschwankungen entsteht keine Beeinflussung der Federung. Einfache Montage der Elemente, keine aufwendige Wartung, leichtes auswechseln der Kissen.The invention creates a high-performance spring system with high spring comfort and low weight. The manufacturing costs must be within economic limits. Temperature fluctuations do not affect the suspension. Simple assembly of the elements, no complex maintenance, easy replacement of the cushions.

Montagebeispiel der Erfindung wird anhand der Fig. 1-3 erläutert.An example of the assembly of the invention is explained using Fig. 1-3.

Fig. 1 kann nur in Konstruktion eingebaut werden die auf allen Seiten eine Führung aufweisen, parallel zueinander sich bewegen, und zwei Begrenzungsanschläge vorhanden sind.Fig. 1 can only be installed in structures that have a guide on all sides, move parallel to each other, and have two limit stops.

Fig. 2 hat im inneren Bereich eine Führung mit Höhenanschlag.Fig. 2 has a guide with height stop in the inner area.

Fig. 3 ist wie Fig. 2, nur ist die Führung und der Anschlag im Außenbereich.Fig. 3 is like Fig. 2, only the guide and the stop are on the outside.

Für ein Luftkissen mit dehnbaren Mantel aus Gummi oder ähnlichem dehnbaren Material, vorwiegend für den Fahrradbereich geeignet,
dadurch gekennzeichnet:1. For an air cushion with a stretchable cover made of rubber or similar stretchable material, mainly suitable for bicycles,
characterized: das zwei runde Flanschen (2+3) einen dehnbaren Mantel (1) aufnehmen
der mittels eines Fahrradventils (7) mit Luft befüllt wird. Um das Luftkissen vor Überdruck zu schützen, muß ein Sicherheitsventil (11) eingebaut werden. Das Befüllungsventil (7) kann in Pos. (2) oder Pos. (6) eingebaut werden je nach Bedarf. Position (6+12) dient auch zur Befestigung des Luftkissens. Mit Pos. (6+12) wird auch der Gummimantel an die Flanschen (2+3) gepreßt. Die Flanschen (2+3) sind mit Konussitz versehen, in der der Mantel (1) mit Hilfe von Pos. (4+5) gehalten wird und so eine Dichtheit gewährleistet. Bei Befestigungsbolzen (6+12) muß eine Dichtung eingesetzt werden.two round flanges (2+3) accommodate an expandable jacket (1)
which is filled with air using a bicycle valve (7). A safety valve (11) must be installed to protect the air cushion from overpressure. The filling valve (7) can be installed in position (2) or position (6) as required. Position (6+12) is also used to attach the air cushion. The rubber jacket is also pressed onto the flanges (2+3) using positions (6+12). The flanges (2+3) are provided with a conical seat in which the jacket (1) is held using positions (4+5), thus ensuring a tight seal. A seal must be used for the fastening bolts (6+12). 2.Luftkissen nach Schutzanspruch 12.Air cushion according to claim 1 dadurch gekennzeichnet,characterized, daß außer Fig. 1 noch zwei weitere Fig. 2.+3. möglich sind. Sie unterscheiden sich dadurch, das Fig. 2.+3.Führungen und Längenbegrenzung aufweisen.that in addition to Fig. 1, two further Fig. 2.+3. are possible. They differ in that Fig. 2.+3. have guides and length limitations.
