【考案の詳細な説明】
この考案は、オートバイ等の二輪車の前ホーク
長さ調節装置に関する。[Detailed Description of the Invention] This invention relates to a front fork length adjustment device for two-wheeled vehicles such as motorcycles.
一般に、オートバイ等の二輪車では、前ホーク
は車体の大きさに合せて作られていて、車体の高
さが一定である。前ホークが上下に長さ調節でき
ると、車体のシート高さを運転者の体格に合せて
調節できる等、乗り易く便利になる。 Generally, in two-wheeled vehicles such as motorcycles, the front fork is made to match the size of the vehicle body, and the height of the vehicle body is constant. If the length of the front fork can be adjusted up and down, the seat height of the vehicle can be adjusted to suit the physique of the driver, making it easier and more convenient to ride.
この考案は、かかる点に鑑み、前ホークの長さ

連結片１１の長さ分だけ長くすることができる。 In general, the front forks are designed to rotatably support the front wheels 2 at the lower ends of the left and right front forks 1, and the upper part supports the under bracket 5 of the steering shaft, which is rotatably supported on the head pipe 4 of the vehicle body 3. A screw body 6 is welded to the inside of the upper end of the front fork 1 through the hole, and the upper end is brought into contact with the lower surface of the upper bracket 7 of the steering shaft.
It is attached by screwing a tightening bolt 8 onto the threaded body 6. Further, the under bracket 5 is fixed to the left and right front forks 1 by tightening the slots formed in the holes of the under bracket 5 with bolts (not shown). Therefore, the present invention provides a threaded rod 9 protruding from the lower end,
A connecting piece 11 having a screw hole 10 at its upper end is provided.
The connecting piece 11 has a chamfer 12 on its outer periphery with a spanner.
has been applied. The connecting piece 11 is connected to the upper end of the front fork 1 by screwing the threaded rod 9 onto the threaded body 6 of the front fork 1. At that time, a stepped portion 13 is provided at the bottom of the connecting piece 11.
By providing this and fitting it into the upper end of the front fork 1, it becomes a spigot and can be reliably connected. Then, the upper end of the connecting piece 11 is aligned with the lower surface of the upper bracket 7, and the tightening bolt 8 is tightened into the screw hole 10. By doing so, the front fork 1 can be made longer by the length of the connecting piece 11.

運転者の体格に合せられる。又、車高を高くする
と、地上の高さ（車体下部と地面との間隔）も大
きくなり、悪路の走行に適するようになる。 Therefore, when attaching the connecting piece 11, remove the bolt 8 of the upper bracket, loosen the bolt of the under bracket 5, shift the front fork 1 downward, and then attach the connecting piece to the upper end of the fork using a threaded rod. Screw it in, align the upper end of the connecting piece 11 with the lower surface of the upper bracket, and insert the tightening bolt 8 into the screw hole 10.
Tighten. Thereafter, the bolts of the under bracket are tightened to fix the under bracket 5 to the front fork 1, thereby increasing the length of the fork by the length of the connecting piece. In this way, the seat height etc. of the vehicle body 3 can be adjusted,
It can be adapted to the physique of the driver. Furthermore, when the vehicle height is increased, the height above the ground (the distance between the lower part of the vehicle body and the ground) also increases, making it suitable for driving on rough roads.

都合がよい。又、連結片はスパナによつて簡単に
着脱できて、着脱作業が容易にできる。 As explained above, this invention provides a connecting piece with a threaded rod protruding from the lower end and a screw hole at the upper end, and the threaded rod of the connecting piece is screwed into the threaded body at the upper end of the front fork. Since the upper end is fastened to the upper bracket with a tightening bolt, by attaching and removing the connecting piece to the upper end of the front fork,
The length of the front fork can be adjusted, the vehicle height can be adjusted, and the riding position and ground clearance can be conveniently adjusted. Further, the connecting piece can be easily attached and detached using a wrench, making attachment and detachment work easy.
