DESCRIPTION:
BRIEF SUMMARY
The invention relates to a saddle structure for bicycle saddles, in particular sport saddles, comprising a fastening part capable of being adjusted relative to a seat pillar.
With bicycle saddle structures, it is common to connect the same with the seat pillar in a manner so as to be pivotable about a pivot axis extending transverse to the seat pillar. Usually, toothed discs are used as fastening parts, which allow for the stepwise adjustment of the inclination of the saddle relative to the seat pillar. Furthermore, common saddle fastenings allow for height adjustments relative to the seat pillar, wherein the fastening part usually is connected with a tube portion inserted in the seat pillar and fixed within the seat pillar in a positive and force-transmitting manner by clamping. By such a known configuration of the fastening part, adjustment in terms of both inclination and height is basically feasible. Yet, such an adjustment, as a rule, requires tools and allows for a limited adjustability only, the comfort of the saddle, thus, being not always ensured.
The invention aims at providing a saddle structure comprising a fastening part which enables the particularly easy and simple regulation and fine adjustment of saddle settings. In addition, the invention aims at providing more freedom for any intended adjustment in order to thereby obtain a more precise fine adjustment and a higher comfort. To solve this object, the configuration according to the invention essentially consists in that the saddle structure comprises at least two separate means for adjusting the height in the front and rear regions of the saddle. By at least two separate means being provided for adjusting the height in the front and rear regions of the saddle, concerted adaptation may be obtained in a particularly simple manner and, as a rule, substantially more quickly. In principle, one of these two means for adjusting the height might be the known pivotability of the saddle. Such a pivotability, however, only provides for the simultaneous lifting or lowering in a front or rear region and lowering and lifting, respectively, in the respective opposite region. It is only the additional separate means provided for adjusting the height on the respective opposite side, that allows for fine adjustment substantially raising the comfort. In a particularly simple manner, the height-adjustable means may be designed as supports or bolts including spring and/or dampening elements, wherein such supports or bolts are each arranged in the front and rear regions of the saddle in order to ensure appropriate fine adjustment.
In order to further improve the precise adjustment required for the optimum comfort, the configuration advantageously is devised such that the fastening part capable of being adjusted relative to the seat pillar is designed as a slide displaceable transverse to the axis of the seat pillar in the longitudinal direction of the saddle. By such an additional displacement relative to the saddle, the optimum position relative to the handlebar may be adjusted and, in such an optimum position, the inclination of the saddle may be set with a view to obtaining the best comfort. With the hitherto known adjustment means, the subjective distance relative to the handlebar was adjusted at the same time by appropriately tilting the saddle about an axis extending transverse to the axis of the seat pillar, which, of course, could not simultaneously result in an improved comfort of the saddle. It is only by the separation of the two functions of adjustment relative to the handlebar as well as adjustment of the saddle in the correct position relative to the handlebar, that a substantial enhancement of the comfort of the saddle has become feasible.
Advantageously, the configuration according to the invention is devised such that the height-adjustable supports are designed as screw spindles, thereby rendering adjustment particularly quick and simple. In order to be able to apply also large adjustment forces quickly and safely without resorting to the aid o
