Abstract

The lightweight saddle for bicycles has carbon roving drawn through metal tubes in the clamping region of the saddle frame, and the protruding ends of the carbon roving are resinified with the saddle cover. In the clamping region the metal tube has an oval or round cross section. Defined areas of the saddle are covered by a padding of leather, plastic or textile fabric. The weight of the fabricated, unpadded saddle does not exceed 100 grammes.

Description

1. Aufgabe1st task

Die Erfindung betrifft einen Formkörper für Fahrradsättel, insbesondere Rennradsättel, der komplett aus einem Carbon Kunststoff gefertigt ist.The invention relates to a molded body for bicycle saddles, in particular Road bike saddles made entirely from a carbon plastic.

In der Vergangenheit diente Metall, insbesondere Stahl, als Material für Sattelgestelle. Dadurch wurde das Gewicht des Sattels erhöht, was sich nachteilig, speziell bei Rennrädern, auswirkt.In the past, metal, especially steel, was used as a material for Saddle rails. This increased the weight of the saddle, which is disadvantageous especially with racing bikes.

Es ist aber bei Rennrädern sehr erwünscht, jede Möglichkeit der Gewichtseinsparung auszunutzen. Durch Austausch der Metallgestelle durch Kunststoffmaterialien können Fahrradsättel, insbesondere Rennradsättel, mit einem Gesamtgewicht von unter 100 Gramm hergestellt werden.But it is very desirable for racing bikes, every possibility of saving weight to take advantage of. By replacing the metal frames with plastic materials can bicycle saddles, especially road saddles, with a total weight of less than 100 grams.

Ziel der Erfindung ist es nun, einen kompletten Sattel der eingangs ausgeführten Art vorzusehen, der nicht nur eine außerordentlich geringe Masse aufweist, sondern überdies eine hohe Festigkeit, bei vergleichsweise geringem Herstellungsaufwand, bietet.The aim of the invention is now a complete saddle of the type mentioned provide that not only has an extremely low mass, but also high strength, with comparatively low manufacturing costs, offers.

2. Lösung2nd solution Gestellframe

Dieses Ziel kann nur erreicht werden, wenn das Gestell und die Satteldecke naß in naß miteinander verbunden werden. Zu diesem Zweck wird ein mit Harz vorgetränktes Bündel Carbonrovings, umhüllt mit einem Carbonschlauch durch ein VA Rohr gezogen (zwei solcher Bündel, im Klemmbereich parallel angeordnet, ergeben das Sattelgestell). Anschließend werden diese so vorgefertigten Carbonschläuche (Gestell) über der in der darunterliegenden Form befindlichen Satteldecke fixiert und die überstehenden Enden naß in naß mit dieser verharzt. Das Harz der Carbonschläuche und der Satteldecke ist zu diesem Zeitpunkt noch nicht ausgehärtet. Somit entsteht nach dem Aushärten (tempern) eine kraftschlüssige Verbindung. Im Klemmbereich für die Sattelstütze sind die Carbonschläuche des Gestells durch Edelstahlröhrchen gegen mechanische Beschädigung geschützt.This goal can only be achieved if the frame and saddle cover are wet in wet to be connected. For this purpose, one with resin pre-soaked bundle of carbon rovings, covered with a carbon tube through a VA tube pulled (two such bundles, arranged in parallel in the clamping area,  result in the saddle frame). Then these are prefabricated Carbon tubes (frame) over the one in the shape below Fixed the saddlecloth and resinified the protruding ends wet on wet. The Resin of the carbon tubes and the saddlecloth is not yet at this point hardened. This creates a non-positive after hardening Connection. The carbon tubes of the are in the clamping area for the seat post Protected against mechanical damage by stainless steel tubes.

SatteldeckeSaddlecloth

Die Form, aus der der Sattel gefertigt wird, wurde so gebaut, dass der Sattel außen eine spiegelglatte Oberfläche besitzt (Negativbauweise). Die Oberfläche des Sattels wird aus einer Lage Carbongewebe (Köperbindung), laminiert. Die weiteren Gewebelagen sind aus Carbongewebe (Leinwandbindung), hergestellt. Zur Zugentlastung der Sattelkante wird ein umlaufender Carbonroving eingearbeitet. Um das Auseinanderbrechen der Carbonsatteldecke unter extremsten Belastungen zu verhindern, wird eine Gewebelage aus Aramidfasern zwischen den Carbongewebelagen eingelegt. In Längsrichtung des Sattels werden zusätzlich Rovings aus Aramidfasern eingelegt, die die Satteldecke im Bereich der Anlenkpunkte des Gestells verstärken.The shape from which the saddle is made was built so that the saddle is outside has a mirror-smooth surface (negative construction). The surface of the saddle is laminated from a layer of carbon fabric (twill weave). The others Fabric layers are made of carbon fabric (plain weave). For A circumferential carbon roving is incorporated in the strain relief of the saddle edge. Around the breaking apart of the carbon saddle blanket under extreme loads prevent a fabric layer of aramid fibers between the Carbon fabric layers inserted. In the longitudinal direction of the saddle are additional Aramid fiber rovings inlaid the saddlecloth in the area of the Reinforce the pivot points of the frame.
