Abstract

PURPOSE:To absorb and relieve vertical vibration or impact force applied to a saddle during cycling by means of a simple mechanism. CONSTITUTION:In a saddle 4, a cushioning member 9 consisting of a rubber bush type torsion damper and the like, which absorbs and reduces vibration to the vertical direction of the saddle 4, is connected flexibly between a point 7a of a seat pillar 7 in a seat post and a base end part 8a of a saddle mounting stem 8 to which the saddle 4 is mounted.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bicycle saddle support structure, and more particularly to a bicycle saddle support structure that absorbs and alleviates vertical vibrations and impact forces applied to the saddle portion during bicycle travel. .

[0002]

2. Description of the Related Art Conventionally, as a bicycle having a shock absorbing function of absorbing and absorbing vertical vibration and impact force applied to a saddle portion while riding a bicycle, a metal coil spring is interposed between a frame body and a saddle. It is common to do so.
Further, in addition, as shown in FIG. 4, for example, a structure in which the saddle 4 is supported by the FRP spring 3 made of fiber reinforced plastic (FRP) on the top tube 2a of the frame body 2 of the bicycle 1, Also in recent ones,
As shown in FIG. 5, a seat post 5 that supports the saddle 4 in order to positively measure shock absorption is proposed in which a hydraulic damper mechanism 6 (shock absorber) utilizing hydraulic-pneumatic pressure is incorporated. .

[0003]

However, the above-mentioned conventional ones have a problem that the structure is complicated and expensive, and there are many sliding surfaces, so that maintenance of the mechanism itself is troublesome. was there. The present invention was devised by focusing on such conventional problems, and it is possible to absorb and mitigate the vertical vibration and impact force applied to the saddle during bicycle traveling by a simple mechanism, and the structure is simple. Therefore, it is an object of the present invention to provide a bicycle saddle support structure that can be manufactured and used at low cost and that saves labor for maintenance and the like.

[0004]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention provides a cushioning member for absorbing and relaxing a vertical vibration of a saddle between a seat pillar of a seat post and a saddle mounting stem for mounting a saddle. The gist of the invention is to connect them so that they can be bent. The cushioning member is configured by integrally fixing a rubber-like elastic body between an inner cylinder connected to the seat pillar via a shaft and an outer cylinder fixed to the saddle mounting stem side, Hard rubber and a coil-shaped leaf spring are used as the rubber-like elastic body.

[0005]

The present invention is constructed as described above, and a rubber bush type cushioning member, that is, a torsion damper is flexibly connected between the seat pillar and the saddle mounting stem. The vertical movement of the seat post supporting the saddle is converted into rotational movement, and the elastic force of the cushioning member at this time attenuates vertical vibration and impact force. As a result, it is possible to obtain a lightweight and simple saddle support structure having excellent vibration proofing properties, and it is also possible to provide excellent riding comfort during traveling.

Embodiments of the present invention will be described below with reference to the accompanying drawings. The same components as those in the conventional example are designated by the same reference numerals and the description thereof will be omitted. FIG. 1 shows an enlarged side view of a saddle 4 embodying the present invention. The saddle 4 includes a tip 7a of a seat pillar 7 of a seat post 5 and a base end 8a of a saddle mounting stem 8 to which the saddle 4 is attached. Between,
A cushioning member 9 composed of a rubber bush type torsion damper or the like that absorbs and absorbs vibrations of the saddle 4 in the vertical direction is flexibly connected.

As shown in FIGS. 2 and 3, the cushioning member 9 includes an inner cylinder 11 connected to the seat pillar 7 via a shaft 10 and an outer cylinder 12 fixed to the saddle mounting stem 8 side. The rubber-like elastic body 13 is integrally fixed by baking or the like between the two, and as the rubber-like elastic body 13, hard rubber and a coil-shaped leaf spring are used. Although the cushioning member 9 is provided on the base end portion 8a of the saddle mounting stem 8, it may be mounted on the distal end side 8b of the saddle mounting stem 8.

The present invention, as described above, uses the seat pillar 7
A seat post 5 that supports the saddle 4 by connecting a rubber bush type cushioning member 9, that is, a torsion damper so that the saddle 4 can be bent.
To convert the vertical movements of the above into rotational movements, and at this time, the vertical vibration and the impact force are attenuated by the elastic force of the rubber-like elastic body 13 such as the hard rubber and the coil-shaped leaf spring forming the cushioning member 9. Is. As a result, it is possible to obtain a lightweight and simple saddle support structure having excellent vibration proofing properties, and it is also possible to provide excellent riding comfort during traveling.

[0009]

As described above, according to the present invention, between the seat pillar of the seat post and the saddle mounting stem for mounting the saddle, a cushioning member that absorbs and absorbs vibration of the saddle in the vertical direction is bendably connected. Therefore, it is possible to absorb and mitigate vertical vibrations and impact forces applied to the saddle when riding a bicycle with a simple mechanism, and the simple configuration makes it possible to manufacture and use at low cost, and at the same time to perform maintenance and the like. There is an effect that can be omitted.
