Abstract

The functional integrated bicycle seat post is designed in fork shape so that it has two springy fork blades (1,2) at both ends to make into one piece. A connected end (5) of the seat post is designed for assimilation in the bicycle frame. The springy fork blades are designed at its ends (3,4) for mounting to the seat.

Description

Es ist bekannt, dass Fahrstöße im Fahrbetrieb durch die entsprechende Bauweise einer Sattelstütze an einem Fahrrad gedämpft werden können. Am meisten verbreitet auf dem Markt sind unter Anderem Teleskop-Sattelstützen, oder Sattelstützen mit einer Parallelogramm Kinematik.It is known that driving collisions can be damped by the corresponding construction of a seat post on a bicycle while driving. Telescopic seatposts, or seatposts with a parallelogram kinematics, are the most popular on the market.

Die Teleskopsattelstützen bieten zwar eine variable Einstellung der Dämpfung und Federung, besitzen jedoch mehrere Nachteile, bedingt durch die Veränderung der Sitzhöhe während der Fahrt und durch den ungünstigen Winkel zwischen der Kraftrichtung von Stößen und dem Eintauchen des Teleskops.Although the telescopic seatposts provide variable damping and suspension adjustment, they have several disadvantages due to the change in seat height during the ride and the unfavorable angle between the direction of impact force and the depth of the telescope.

Die Sattelstützen mit Parallelogramm Kinematik erfüllen die Aufgaben deutlich besser als die Teleskopsattelstützen sind aber durch ihre mehrteilige und aufwändige Bauweise schwer und ihre Federungseigenschaften sind massgeblich von einem im Parallelogramm eingebauten Dämpfungselement abhängig.The seatposts with parallelogram kinematics perform the tasks significantly better than the telescopic seatposts are heavy but by their multi-part and complex design and their suspension properties are significantly dependent on a built-in parallelogram damping element.

Eine weitere Lösung bieten die Sattelstützen Pat. ( DE 603 09 188 T2 ) und Pat. ( EP 1 476 346 B1 ). Die im Patent ( DE 603 09 188 T2 ) beschriebene Sattelstütze ist durch das starre Parallelogramm in ihrem Federweg stark eingeschränkt. Bei der im Pat. ( EP 1 476 346 B1 ) beschriebenen dreiteiligen Bauweise ist die Einstellung der Steifigkeit und der Energieabsorption nur durch die Veränderung der freien Länge der Dämpfungsstäbe möglich (Patentanspruch 13). Dies bedeutet für einen schweren Fahrer eine Verkürzung des Federweges oder eine lokale Überlastung des Materials, der nur durch entsprechend massive Bauweise und somit zusätzlichem Gewicht begegnet werden kann.Another solution is provided by the seatposts Pat. DE 603 09 188 T2 ) and Pat. EP 1 476 346 B1 ). The in the patent ( DE 603 09 188 T2 ) described seat post is severely limited by the rigid parallelogram in their travel. In the Pat. EP 1 476 346 B1 ) described three-piece construction, the adjustment of the stiffness and the energy absorption only by changing the free length of the damping rods is possible (claim 13). This means for a serious driver a shortening of the spring travel or a local overload of the material, which can only be met by correspondingly solid construction and thus additional weight.

Die Innovationshöhe und Neuheit der vorliegenden Erfindung besteht darin, dass sich die Sattelstütze durch eine entsprechende Bauweise und Materialauswahl von den oben ausgeführten Versionen durch die unten aufgeführten Patentansprüche abgrenzt und durch die Entwicklung eines neuen Verfahrens erstmals die Fertigung einer voll integrierten Sattelstütze, die ein Stoß dämpfendes Verhalten mit einer an das Fahrergewicht einstellbaren Dämpfung und Federung ohne zusätzliches Gewicht kombiniert.The innovation level and novelty of the present invention is that the seat post demarcated by the appropriate construction and material selection of the above versions by the claims listed below and the development of a new method for the first time the production of a fully integrated seat post, which dampens a shock Behavior combined with an adjustable to the driver's weight damping and suspension without additional weight.

Diese Aufgaben sind durch die in den Patentansprüchen 1 bis 5 dargestellten Merkmalen gelöst. Die in diesen Patentansprüchen vorgeschlagene Bauweise gleicht einem verstrebter Ausleger (Galgenprinzip), deren Streben über einen einstellbaren Winkel die Traglast und Steifigkeit/Dämpfung/Federung vorgibt.These objects are achieved by the features shown in the claims 1 to 5. The proposed in these claims construction is similar to a braced boom (gallows principle), the pursuit over an adjustable angle, the load and stiffness / damping / suspension specified.

Hierbei bildet der Sattel den Ausleger, die vordere(n) Gabelscheide(n) die Sitzposition und die hintere(n) Gabescheide(n) die für den Fahrkomfort maßgeblich verantwortliche Stützstrebe. Je größer der Abstand zwischen den Gabelscheidenenden nach Patentanspruch 2 (3, 4) ist, umso kleiner ist der Hebel (freier Ausleger) und somit größerer Einfluss der hintere(n) Gabelscheide(n) auf die Steifigkeit, Dämpfung und Federung des Gesamtsystems. Durch die Verwendung eines zum Beispiel geeigneten Exenter-Bolzens (7), wird die Veränderung an der Länge der hinteren Gabelscheide (2) ermöglicht, oder durch die Parallelverschiebung der beiden Gabelscheiden (1, 2) zu einander realisiert. Die Ausführungsbeispiele der Erfindung sind in der Zeichnungen dargestellt.Here, the saddle forms the boom, the front fork shank (s) the sitting position and the rear fork (s) (n) the responsible for driving comfort support strut. The greater the distance between the fork leg ends according to claim 2 ( 3 . 4. ), the smaller the lever (free boom) and thus greater influence of the rear fork sheath (s) on the rigidity, damping and suspension of the entire system. By using an example suitable eccentric bolt ( 7 ), the change in the length of the rear fork sheath ( 2 ) or by the parallel displacement of the two fork blades ( 1 . 2 ) realized to each other. The embodiments of the invention are illustrated in the drawings.
