Description

DETAILED DESCRIPTION OF THE INVENTION INDUSTRIAL APPLICATION FIELD The present invention relates to a reinforcement device for a unicycle saddle to be used for sports, music performances and the like.

Conventional technology Conventionally, unicycle saddles have the upper end of a seat post welded to a mounting bracket, provided integrally with the mounting bracket, and the mounting bracket is fastened and fixed to the back of the saddle base with bolts and nuts, and the seat post is installed. It was made.

Problems to be Solved by the Invention There is a problem in strength when a heavy person, that is, a person three to four times as heavy as a normal person uses the conventional unicycle saddle. Also, in long distance marathon competitions, it is sometimes carried out to lift the buttocks from the saddle by putting your hands on the front of the saddle and lose weight on the buttocks,
There was a drawback that the front of the saddle was deformed downward and the running was not stable.

Means for Solving the Problems Provided is a wire or an iron plate or a synthetic resin material, a support having front and rear ends formed in an annular mounting portion, and an intermediate portion of this support is mounted on a saddle base by a mounting metal whose upper end is welded and connected. A pair of supports are arranged corresponding to both sides of the seat post, the respective annular mounting portions at the front and rear ends are fixed to the saddle base, and an intermediate portion of the support is fixed to the seat post with a fixing bracket, and the seat post is saddle-mounted. A seat post reinforcing device for a unicycle saddle characterized by reinforcing with respect to a base.

The front end or the rear end of the support may be integrally connected by a connecting rod.

A hole for a tightening bolt is opened in the middle part of the support at a distance from the front to the back, and the middle part of the support corresponds to both sides of a seat post attached to the saddle base by a mounting metal whose upper end is welded and connected. The annular mounting portions at the front and rear ends are respectively fixed to the saddle base, and an intermediate portion of the support is fixed to the seat post by a bolt inserted into the hole for the tightening bolt and a nut screwed to the bolt. Then, the seat post may be reinforced with respect to the saddle base.

A plate is welded and connected to an intermediate portion of the support, and a plate of the intermediate portion of the support is provided with a pair of supports corresponding to both sides of a seat post attached to a saddle base by a mounting metal whose upper end is welded, The annular mounting portions at the front and rear ends are respectively fixed to the saddle base, and a plate at an intermediate portion of the support is applied to the seat post, and a bolt is inserted into the tightening bolt hole provided separately in the front and rear in the play. Further, a seat post reinforcing device for a unicycle saddle, characterized in that a nut is screwed into a tip of each of the nuts and the plate is fixed to the seat post, and the seat post is reinforced with respect to the saddle base.

In a unicycle saddle in which a mounting post with the upper end of the seat post welded is fixed to the saddle base and the seat post is arranged on the saddle base, a reinforcing plate is welded to a side periphery of the upper end of the seat post and the mounting post, And a seat post reinforcing device for a unicycle saddle characterized by reinforcing the above.

Function Since the device is constructed as described above, the overall strength between the seat post and the saddle base is increased by being supported by the support, and it is reinforced to prevent the heavy person from riding or jumping. Is what is done.

Practical Examples Hereinafter, this embodiment will be described with reference to the drawings. FIGS. 1 to 4 show a first embodiment, in which 1 is a unicycle saddle of the present invention, and a saddle base 2 formed of a synthetic resin material. A cushion material 3 is placed, and a saddle top 4 in which a synthetic resin sheet is sewn in a hat shape is covered thereon, and the lower end of the saddle top is folded inside the side wall 2a of the saddle base 2,
The inner end is squeezed and fixed by a stop claw 5 attached to the inner surface of the side wall, and furthermore, in the embodiment, covers 6 and 7 for protecting the saddle top are attached to the front and rear portions.

In the unicycle saddle 1 according to the present invention, the bending supports 8 made of wire having an appropriate diameter are fixed to the annular mounting portions 9, 10 at the front and rear ends thereof with bolts 11 and nuts 12 on the bottom surface of the saddle base 2. At the same time, the respective intermediate lower bending portions 13 are fixed to the seat posts 14 by fixing fittings 15.

The fixing bracket 15 clamps the seat post with the clamp band 16, and has a lower bend forming portion between the supports 8, 8 on both sides.
The support receiving fittings 18 and 18 having the support receiving groove 17 for fitting the lower end 13 on the outer surface of the lower edge are inserted into the clamp bolt 16 which is inserted into the clamp band 16 and protrudes from both sides, and is inserted into the clamp band 16 from both sides. After connecting and further fitting the holding members 20 and 20 from the outside thereof, the nuts 21 and 21 are screwed into the clamp bolts 19, and the holding members 20 and 20 and the support receiving members 18 and 18 are connected to the clamp band 16. Tightening, support 8,
8 is fixed to the seat post 14.

FIGS. 5a and 5b are perspective views showing an embodiment in which the front and rear ends of the supports 8, 8 arranged on the left and right sides of the left seat post 14 are integrally provided by a connecting rod 23. 5a
Fig. 5b shows the case where the connecting members are welded and integrally connected.

FIGS. 6 and 7 show a second embodiment in which a plate 15a is arranged in the middle of the supports 8, 8, in which holes 24 for tightening bolts are opened at four corners, and the inner surface is adapted to the tightening shape. It is formed on a curved surface. Then, bolt the seat post 14 from both sides
Then, the supports 8 and 8 are fixedly fastened with the nut 26 and the nut 26.

FIGS. 8 and 9 show an embodiment in which the support 8 is provided by an iron plate or a synthetic resin material. Tightening bolt holes 24, 24 are provided directly in the middle of the support 8 and are separated from each other. This shows an embodiment in which the intermediate portions of the supports 8 and 8 are fixed to the seat post 14 by bolts 25 and nuts 26.

In the above embodiment, the bolts 11 and the nuts 12 for fixing the front and rear ends of the supports 8 and 8 to the saddle base 3 are also used for fixing the covers 6 and 7, but may be independent. Also, the fixing portion may be a saddle-based side wall, and is not limited.

FIG. 10 shows a mounting plate 22 with the upper end of the seat post 14 welded.
In a unicycle saddle in which the seat post 14 is fixed to the saddle base and the seat post 14 is arranged on the saddle base, a reinforcing plate 27 is welded to the side periphery of the upper end of the seat post 14 and the mounting metal 22 to reinforce the seat post 14. This is an example.

Effect Since the present invention is as described above, it is possible to attach a support which is a reinforcing metal member to a conventional general standard unicycle saddle without modifying the saddle. Since it can be made to withstand the use of a person of about four times the weight of the physique and can use parts of a general bicycle saddle as a joint fitting, the cost is low and advantageous.

As described above, the present invention has an excellent reinforcing effect at a low cost and is easy to mount.
