Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a bicycle saddle used for a running bicycle, a bicycle machine for indoor training, or the like.

(Prior Art) A conventional bicycle saddle has a vertically elongated isosceles triangular shape that widens at the rear, and can be attached to the center of the bicycle body by appropriately arranging cushioning material.

When using the bicycle, the buttocks are placed on the bicycle saddle and the pedals are pedaled in that position.

[Problem to be solved by the invention] However, everyone who rides a bicycle or rides long distances experiences pain in their buttocks and lower back while riding.
This tendency is even stronger with drop handlebar types and road racers that require forward leaning.

In addition, the fatigue from riding a bicycle remained even after the next day, and was one of the reasons why they avoided cycling.

Furthermore, with conventional bicycle saddles, the pubic symphysis of the pelvic floor comes into contact with the rod-shaped portion at the tip of the saddle for a long period of time, causing significant fatigue to the ligaments in that area due to pressure from body weight and pedaling. There is a problem in that the accumulation of fatigue may shift the pelvis and affect the lumbar vertebrae.

The present invention has been made in view of the above circumstances, and provides a bicycle saddle that does not generate excessive force on the buttocks even when riding a bicycle for a long time, and also does not hinder pedaling. The purpose is to

[Means for Solving the Problems] The bicycle saddle according to claim 1 which meets the above object has the following features:
The seat base is attached to a fixed part attached to the bicycle body so as to be rotatable left and right.

The bicycle saddle according to the second aspect of the present invention is the bicycle saddle according to the first aspect, in which the front portion of the seat is rounded.

(Function) In the bicycle saddle according to claim 1, the seat base is attached to the fixed part attached to the bicycle body so as to be rotatable left and right. When placing the seat on the seat and stepping on the pedals, the seat rests as it is, so you can step on the pedals with your buttocks resting stably on the seat, and the load is reduced like a conventional bicycle saddle. Since it is not concentrated only in the central part of the pelvic floor, fatigue is reduced.

In the bicycle saddle according to claim 2, since the front part of the bicycle saddle is rounded, the rod-like part of the saddle does not dig into the root part of the foot like in a conventional bicycle saddle. There are no bumps, so you can rest your butt on the pedestal in a stable manner.

(Examples) Next, examples embodying the present invention will be described with reference to the attached drawings to provide an understanding of the present invention.

Here, FIG. 1 is a plan view of a bicycle saddle according to an embodiment of the present invention, the second is a sectional view taken along arrow A-A in FIG. 1, and FIG. 3 is a sectional view taken along arrow BB in FIG. It is a diagram.

As shown in FIGS. 1 to 3, a bicycle saddle 10 according to an embodiment of the present invention includes an upper seat 11 and an upper seat 11.
The support vibe 12 provided inside the support vibe 1
2 through bearings 13 and 14, and an upright vibrator 16 attached to the center of the outer cylinder 15.

Note that the outer cylinder 15 and the upright vibrator 16 constitute a fixing part 17.

As shown in the first part, the seat 11 has a rounded front part, a core material 18 manufactured by pressing an iron plate is arranged inside, and the outside is covered with a cushion material 19, and the seat 1
1 is covered with a cover material 11a made of, for example, synthetic leather, synthetic resin, cloth, or natural leather.

The support vibrator 12 is made of iron, and flanges (mounting refers to plates) 20 and 21 are provided on both sides.
It is attached to the core member 18 with screws in the vertical direction (referring to the direction in which the bicycle travels), and it is preferable to use a dollar hair ring for the bearing of the support vibe 12, but an oil-free bushing may also be used. An adjustment device 22 for adjusting the rotation angle of the seat 11 is provided on the outer cylinder 15 to which the outer cylinder 15 made of an iron vibrator is rotatably attached via 13.14. The adjustment device 22 is a second
As shown in the figure, it is composed of threaded plates 23.24 provided on both sides of the outer cylinder 15 and bolts 25.26 with nuts screwed onto the threaded plates.
The maximum rotation angle can be adjusted by turning. Although the two-piece plates 23 and 24 are attached to the rear part of the outer cylinder 15 in this embodiment, they can also be attached to the front part, and the adjustment device 22 on the cheek is not limited to this embodiment. It is not necessary that the rotation angle of the seat 11 be adjusted. Further, since the adjustment device is an accessory, it is not necessarily essential.

Further, a cushioning material 27.2B made of rubber or plastic is provided at the tip of the bolt 25.26, so that when the tip of the bolt 25.26 hits the iron core material 18,
It is designed to make no sound. Note that it is also possible to attach this conflicting material to the inside of the core material 18.

One end of an upright vibrator 16 is fixed to the center of the outer cylinder 15, and the upright vibrator 16 allows the bicycle saddle 10 to be attached to the bicycle body.

Therefore, when using this bicycle saddle 10,
First, the bicycle saddle 10 is attached to the bicycle body so that the upper rudder support pipe 12 is spaced in the front and back direction.

When you put your butt on this, the tip of the base 11 is rounded, so you can sit with your butt on it, and when you step on the pedals of a bicycle, you can extend your legs, but in this case The bicycle saddle on which the buttocks rest also rotates in response to the movement of the buttocks, allowing the user to pedal the bicycle without any trouble.

Therefore, you can ride a bicycle without getting pain in your butt.

In the above embodiment, the top of the seat is flat, but it is also possible to raise the center part a little to match the shape of the buttocks without digging into the buttocks. It is also possible to raise the back of the seat slightly and provide a lumbar rest, or in some cases a backrest.

In the above embodiment, the screw plates 23 and 24 are mounted downward so that the rotation angle of the seat 11 can be adjusted to a large extent, but the rotation angle of the seat 11 can be reduced by moving it horizontally or upwards. It is also possible to
It is also possible to provide an identification stopper with a cushioning material (rubber, spring, etc.) at a rotation angle of 10 to 45 degrees to the left and right.

Furthermore, in the above embodiment, the seat 11 is arranged horizontally with respect to the front-rear direction, but it is also possible to tilt it forward within a suitable angle range (for example, 5 to 15 degrees). .

(Effect of the invention) As is clear from the above explanation, the bicycle saddle according to claim 1 rotates from side to side, so that the bicycle saddle can be stably placed on the bicycle saddle. I can ride a bicycle.

Therefore, unlike conventional fixed saddles, the bicycle saddle according to claim 2, which allows a bicycle to be ridden without the front end of the saddle digging into the buttocks and causing problems to the pelvis, muscles, etc., furthermore has a seat base. Since the front part of the bicycle is rounded, there is no fear that the seat will dig into your butt, and you can ride the bicycle while sitting on the seat in a stable manner.
