Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a front wheel stabilizing device for a kick board, and more particularly to a front wheel stabilizing device for a kick board that prevents the front wheel from rotating more than a predetermined angle in the left-right direction so as not to fall down.

[0002]

[Prior art]

 Today, kickboards are very fashionable, foldable and portable. Of course, the most important thing about this kickboard is that it can be safely driven, but unfortunately, the kickboards seen today are often slippery and fall when running. The main reason for this is that there is no device to limit the rotation of the kickboard front wheel, so the front wheel can rotate 360 degrees, and if the front wheel rotates more than a predetermined angle, the kickboard falls over.

[0003] That is, as shown in FIG. 1, it is difficult to limit the rotation of the front wheel 2 and the handle 3 during traveling, and the kick board 1 falls down when rotated by 60 degrees or more (see FIG. 2). This is because the front wheel 2 of the kick board 1 rotates 360 degrees by operating the handle 3. Therefore, if the speed increases or the front wheel 2 stumbles with a stone or the like, the front wheel 2 loses direction and rotates greatly, and the vehicle body falls.

[0004]

[Problems to be solved by the invention]

 The present invention solves the above-mentioned problem by setting the angle range in which the front wheels can rotate in the left and right directions, and controlling the direction by the rotation at the allowed angle, preventing the vehicle from becoming incapable of running or falling. It is an object of the present invention to provide a kickboard front wheel stabilizer capable of preventing the kickboard from being prevented.

[0005]

[Means for Solving the Problems]

 In order to solve the above problems, the kickboard front wheel stabilizing device of the present invention is provided between the front wheel and the handle shaft above the fork, and is composed of a pair of positioning rods and a connecting body. A shaft hole is formed through the center of the connecting body, and a handle shaft rod is inserted into the shaft hole. There are fixed portions at both ends of the coupling body, respectively, and the bottom of the stereotactic rod is fixed to both ends of the front wheel shaft core, and the distal end of the stereotactic rod is fixed to the fixed portion, so that a pair of stereotactic rods are formed. Both ends are fixed between the shaft center of the front wheel and the connecting body.

[0006]

[Embodiment]

 Hereinafter, a kickboard front wheel stabilizer according to an embodiment of the present invention will be described with reference to the drawings.

First, as shown in FIGS. 3 and 4, the front wheel stabilizing device of the kick board 1 according to one embodiment of the present invention is installed between the front wheel 2 and the handle shaft 5 above the fork 4. The handle shaft 5 rotates in the left-right direction together with the front wheel 2. The front wheel stabilizing device includes the positioning rods 10 and 20 and the connecting body 30. Through holes 12 and 22 are formed in the bottom portions 11 and 21 of the positioning rods 10 and 20, respectively, and the shaft core screw 6 of the front wheel 2 is screwed into the through holes and can be fixed with a nut 8. ing. A shaft hole 31 extends through the center of the connecting body 30, and the handle shaft 5 is inserted into the shaft hole 31. Further, fixing portions 32, 33 are provided at both ends of the connecting body 30, respectively, and the structures of the fixing portions 32, 33 at both ends are completely the same. The fixing portions 32, 33 are formed with C-shaped holes 34, 35 and small circular holes 39, which are located on locking pieces 36, 37, 361, 371 at the opening points formed in the C-shaped holes 34, 35. 40 and screw holes 41 and 42. Then, the distal end portions 13 and 23 of the positioning rods 10 and 20 are inserted into the C-shaped holes 34 and 35 of the connecting body 30, and the screws 43 are passed through the small circular holes 39 and 40 and the screw holes 41 and 42 are inserted. Through. Thereby, both ends of the positioning rods 10 and 20 are fixed to the shaft core screw 6 of the front wheel 2 and the connecting body 30, respectively.

As shown in FIGS. 5 and 6, when the handle 3 is rotated counterclockwise (FIG. 6 turns left), the handle shaft 5 connected to the handle 3 is also rotated in conjunction with the handle 3. The front wheel 2 rotates in conjunction therewith. Therefore, the positioning rods 10 and 20 also rotate accordingly. At this time, the positioning rod 20 presses the connecting rod 7 (one end of the connecting rod 7 is connected to the fork 4 and the other end is connected to the front end of the board body 9) so that the front wheel 2 cannot make a large rotation. , You can drive safely. When the handle 3 is rotated clockwise (right turn) according to the same principle, the positioning rod 10 is pushed by the connecting rod 7. As shown in FIG. 6, in the device according to the embodiment of the present invention, the rotation of the front wheel 2 in the left-right direction is limited by the installation of the positioning rods 10 and 20, and the front wheel 2 rotates at a large rotation (exceeding 60 degrees). ) It is impossible to rotate 360 degrees, which makes the kickboard safer.

[0009]

[Effect of the invention]

 As described above, according to the present invention, it is installed between the front axle and the handlebar axle above the fork, and is composed of a stereotaxic axle and a connector. A shaft hole extends through the center of the connecting body, and a handle shaft rod is inserted into the shaft hole. There are fixed parts at both ends of the connected body.The bottom of the stereotaxic rod is fixed to both ends of the front wheel shaft core, and the tip is fixed to the fixed part of the connected body. Are characterized in that they are fixed between the shaft center of the front wheel and the connecting body. As a result, the rotation of the front wheels and the handlebars in the left-right direction is restricted, enabling safe driving and further preventing the vehicle from tipping over.
