The objects and advantages of the present invention will become apparent from the following detailed description with reference to the accompanying drawings.

First, according to Figures 1 to 4, the scooter of the present invention includes a footrest 10, the footrest 10 is the extension portion 30 is fixed to the front. In the front part, that is, the extension part 30 of the scaffold 10, a curved groove 31 for accommodating the housing 40 is formed at the bottom, and one or more screw holes through which the coupling hole 35 is fitted. And a curved slot 33 along the curved groove 31. The extension portion 30 of the footrest 10 preferably includes a rib 37 extending inwardly of the curved groove 31 and forms a curved slot 33 between the ribs 37. (Figure 2). A bracket 34 is provided to engage the housing 40, and the bracket 34 has two holes 36 formed to fit the coupler 35 to the footrest 10. It can be decomposably coupled to the extension portion 30 of the. The handle 11 is coupled to the extension 30 of the scaffold 10.

The housing 40 is provided in a round shape and forms a pair of edge flanges 402 on the sides thereof, and is coupled to the extension part 30 and the bracket 34 of the scaffold 10 and the edge flanges 402 are It defines or defines the outline of the rim or circular groove 401 formed in the housing 40 and accommodates the ribs 37 of the extension 30 of the scaffold 10. Accordingly, the housing 40 may be relatively rotated and adjusted with respect to the extension part 30 of the footrest 10, and the housing 40 may be moved by the bracket 34 and the coupling hole 35. 10) can be firmly coupled to the extension (30). The housing 40 forms a chamber 41 therein and forms a hole 42 connected to the chamber 41, and the chamber 41 forms one or more notches 44 and extends inwardly. Thus, a pair of opposing projections 47 having two inclined surfaces 43 on each side are formed (Fig. 2).

The wheel shaft 60 has a central portion accommodated in the chamber 41 of the housing 40 and has a hole 61 for accommodating a coupler or a fixed shaft 70 in the central portion thereof, and the fixed shaft 70 ) Is mounted to penetrate through the hole 42 of the housing 40 so that the wheel shaft 60 is rotatably coupled in the housing 40. The fixed shaft 70 is provided at one end and has a head 71 coupled to the housing 40 and is accommodated in a curved slot 33 of the extension portion 30 of the footrest 10 so as to be adjustable and movable. The fixed shaft 70 forms an outer thread 77 at the other end and is screwed to the housing 40 so as to rotatably mount the wheel shaft 60 in the housing 40. The wheel axle 60 and the fixed axle 70 may be rotated using a gasket 73 or a ring or the like to allow the wheel axle 60 to rotate relatively freely with respect to the fixed axle 70. It is preferable to combine. The wheels 65 are rotatably coupled to both ends 62 of the wheel shaft 60 by the coupling holes 64, and one or more notches 63 are formed at the center of the wheel shaft 60. do. The inclined surface 43 provided in the housing 40 allows the wheel shaft 60 to be rotated at a relatively larger rotation angle with respect to the housing 40.

The shock absorbing member, cushion member or spring biasing member 50 is made of rubber or plastic material and is accommodated in the chamber 41 of the housing 40 and has a hole 52 therein for receiving the fixed shaft 70. It is formed and mounted on the housing 40 and the wheel shaft 60 to elastically couple the wheel shaft 60 in the chamber 41 of the housing 40. Two washers or gaskets 51 are rotatably mounted to the fixed shaft 70, which are coupled or fixed to the ends or sides of the spring biasing member 50, each of which is notched 44 of the housing 40. It is coupled to the 63 and the wheel shaft 60 includes one or a plurality of projections (53) extended to return the spring biasing member (50). When the wheel shaft 60 is relatively rotated relative to the housing 40, the spring biasing member 50 is notched 44 and 63 of the housing 40 and the shaft 60. Twisted by engagement of 53, so that the wheel shaft 60 is spring-biased member 50 when the wheel shaft 60 is relatively unrotated or free relative to the housing 40 Will be restored or deflected to its original position.

As shown in Figs. 4 to 6, the housing 40 is relatively rotated and adjusted relative to the extension 30 of the scaffold 10 during operation, wherein the housing 40 is bracket 34 Is coupled to the extension part 30 of the scaffold 10. As shown in FIG. 4, when the fixed shaft 70 is perpendicular to the floor or the horizontal surface 17 of the scooter, the body shaft 60 is relatively rotatable relative to the fixed shaft 70. It may be rotatable or movable in the surface 80 formed parallel to the floor or horizontal surface 17, which will not be easily changed the direction of the scooter.

As shown in FIGS. 5 and 6, the housing is based on the extension part 30 of the footrest 10 so that the fixed shaft 70 is inclined with respect to the floor 17 or the horizontal surface 17 of the scooter. When 40 is relatively adjusted, the wheel shaft 60 is relatively rotated relative to the fixed shaft 70 and the wheel shaft 60 is based on the bottom surface or the extension part 30 of the scooter. It will be moved or rotated on the relatively inclined surface 80 as a result, the footrest 10 and the extension portion 30 of the footrest 10 relative to the wheel shaft 60 relative to It will lose, so the scooter will be able to spin more easily. As shown in FIG. 6, the fixed shaft 70 is closer to the horizontal surface 17 of the scooter than shown in FIG. 5, and as shown in FIG. 6, the scooter is easier than that shown in FIG. Can be rotated. Similarly, when the fixed shaft 70 is parallel to the horizontal plane 17 of the scooter, the scooter will rotate relatively freely relative to the fixed shaft 70.

Next, referring to FIGS. 7 and 8, the housing 40 is rotatably coupled and adjustable via the bracket 34 to the footrest 10 instead of the extension 30 of the footrest 10. 7, or may be directly rotatable and adjustable to the scaffold 10 (FIG. 8). The scaffold 10 may include a curved slot 18 formed to slidably receive the head 71 of the fixed shaft 70.

According to the scooter according to the present invention as described above, it includes a steering device or a rotating mechanism for adjusting the direction or rotation angle of the scooter and has the effect of adjusting it as necessary.
