Claims

[Claims for Utility Model Registration] 1. In a scooter having a fork-shaped frame coupled to a front end of a foot plate, wheels are coupled to a lower end of the fork-shaped frame and a rear end of the foot plate, and each wheel is connected to a rim. two beams arranged parallel to each other, said beams being substantially symmetrical about the geometrical center of said wheel, two transverse bars rotatably supporting a nut; the nut and crossbar are spaced apart from the geometric center of the wheel, the bolt extending through the crossbar and extending through the nut; two plates engaged with each other, extending in the direction of the geometrical center of the wheel, and connected to each other by a block;
The wheel is slidably disposed between and along the beams, the bolt is secured to a nut, an axle extends outwardly from each plate, and the axle of the wheel is connected to the lower end of the fork-shaped frame and the A scooter rotatably supported on a rear end of a foot plate, wherein rotation of said nut causes said plate and shaft to move toward or away from the geometric center of said wheel. 2. Ribs are formed longitudinally on the inner surface of each beam, and grooves are formed on the outer surface of the block opposite said ribs, said grooves being engaged with said ribs so that said plate is formed between the beams. Scooter according to claim 1, characterized in that it is guided to move along a beam. 3. In a scooter having a fork-like frame coupled to the front end of a foot plate, wheels are coupled to the lower end of the fork-like frame and the rear end of the foot plate, and each wheel has an outer rim provided in the wheel. an inner rim, a plurality of spokes disposed between the outer rim and the inner rim, and a pair of beams disposed parallel within the inner rim, the beams being located at the geometric center of the wheel. ribs are formed on the inner surface of each beam, each rib facing each other, a crossbar with a nut is disposed between said beams, and a bolt is connected to the inner rim and the nut. penetrated and engaged;
A locking nut is engaged with the bolt in the vicinity of the inner rim, said locking nut being pivoted to move towards said inner rim to securely secure said bolt, said bolt having a head at one end and a head at the other end. With an enlarged end at the end, the head of the bolt is arranged at a distance from the geometrical center of the wheel, a block with a short tube is fitted onto the axle of the wheel, and two grooves are formed. The bolt is formed into a block for slidably engaging the rib, and the enlarged end of the bolt is rotatably supported within the short tube such that rotation of the head of the bolt causes the shaft of the wheel to A scooter characterized by wheels moving closer to or further away from the geometric center.
