It is a side view of the kick scooter of the embodiment of the present invention. It is a three-dimensional view of the same kick scooter. It is sectional drawing of the principal part of the kick scooter. It is a figure which shows the 1st figure of the same kick scooter. It is a figure which shows the 2nd figure of the same kick scooter. It is a figure which shows the principal part of the kick scooter of other embodiment of this invention.

  1 and 2 show the overall configuration of the kick scooter according to the embodiment of the present invention. The illustrated kick scooter has a board 11, a two-wheeled front wheel 12, and a one-wheeled rear wheel 13. A steering wheel 14 steers the front wheel 12. A handle support 15 is attached to the front end of the board 11 and rotatably supports the handle 14. The reference numeral 16 denotes the rotational axis of the handle 14. The handle support 15 has a folded structure. 17 is the folding part. The foldable portion 17 of the handle support 15 allows the handle to be folded from an upright position as shown to a position close to the board 11 (not shown).

  The front wheel 12 is attached to the steering wheel 14 via a “” shaped bending member 18. As shown in FIG. 3, the bending member 18 is connected so that the upper member 19 and the lower member 20 can be pivoted relative to each other by the pin 21 in the horizontal direction. The upper member 19 is attached to the handle 14, and the front member 12 is attached to the lower member 20. 22 is a road surface, and the front wheel 12 is in contact with the ground. The position of the handle support 15 with respect to the road surface 22 can be changed in the vertical direction by the upper member 19 and the lower member 20 mutually turning around the pin 21.

  An adjustment screw 25 capable of adjusting the position of the handle support 15 from the road surface 22 along the height direction is provided at a position away from the pin 21 in the bending member 18. That is, by screwing the adjusting screw 25 into the top plate 26 of the lower member 20, it is possible to screw upward from the top plate 26 in the opposite direction. 27 is a head of a screw, and the head 27 contacts the top plate 28 of the upper member 19 and acts to push up the top plate 28 so that the upper member 19 and the lower member 20 mutually move around the pin 21 The position of the handle support 15 with respect to the road surface 22 can be adjusted in the up and down direction by turning the vehicle. Reference numeral 29 denotes a nut, which functions as a double nut by interaction with the top plate 26 of the lower member 20 into which the adjustment screw 25 is screwed, thereby acting as a locking for the adjustment screw 25.

  The front wheel 12 is configured such that the left and right wheels 32, 32 are rotatably supported by the front wheel track 31. The front wheel track 31 has a hanger 33 attached to a base plate 36 by a king pin 34 and a bush 35, which has the same configuration as that used for a general skateboard. The front wheel 12 is attached to the handle 14 by attaching the base plate 36 to the lower member 20 of the bending member 18. That is, the front wheel 12 is steered by rotating the base plate 36 by the steering wheel 14.

  As shown in FIGS. 3 and 4, the position 37 at which the wheel 32 of the front wheel 12 contacts the road surface 22 is on the front side of the position 38 where the rotation axis 16 of the steering wheel 14 intersects the road surface 22. However, the handle 14 is configured to be rotatable around the rotation axis 16 in the range of 360 degrees, that is, the entire circumference. For this purpose, the handle 14 can also be rotated 180 degrees around the axis of rotation 16 from the position shown in FIGS. 3 and 4. Then, as shown in FIG. 5, the position 37 at which the wheel 32 of the front wheel 12 contacts the road surface 22 changes to the rear side of the position 38 where the rotation axis 16 of the steering wheel 14 intersects the road surface 22.

  The configuration of the rear wheel 13 will be described. As shown in FIG. 1, the rear wheel 13 is constituted by a swing caster. 41 is a wheel, 42 is a swing part of the caster. Reference numeral 43 denotes a rotational axis for swinging, and the rear wheel 13 is attached to the board 11 such that the rotational axis 43 is inclined upward to the front.

  FIG. 6 shows another example of the configuration of the rear wheel 13. Here, a wedge-shaped spacer 44 is sandwiched between the board 11 and the rear wheel 13 constituted by a swing caster, and by changing the wedge angle of the spacer 44, the rotation axis 43 is obtained. It is possible to change the inclination angle of. For example, by preparing a plurality of types of spacers 44 having different wedge angles, the inclination angle of the rotation axis 43 can be changed by replacing the spacers 44.

  According to the present invention, with the above-described configuration, it is possible to change the forward and upward inclination angle about the rotational axis 43 of the swing for the rear wheel 13 configured by the swing caster. And thereby, the turning performance of the kick scooter can be changed. Normally, as the rotation axis 43 gradually falls from the vertical direction, the swing performance of the rear wheel 13 gradually improves. As a result, the turnability of the kick scooter during traveling also gradually improves.

  In detail, as shown in FIG. 6, by using the spacer 44, the inclination angle of the rotation axis 43 can be directly changed as described above. Alternatively, even if the attachment structure of the rear wheel 13 to the board 11 is not changed, the height of the front end 45 of the board 11 from the road surface 22 is changed, thereby changing the inclination angle of the rotation axis 43 It can also be done.

  That is, when the position of the top plate 28 of the upper member 19 of the bending member 18 is changed in the direction away from the road surface 22 by operating the adjustment screw 25 from the state shown in FIGS. 3 and 4, that is, the state shown in FIGS. When the adjustment screw 25 is operated to lift the top plate 28 of the upper member 19, the front end 45 of the board 11 shown in FIG. 4 is displaced upward, as a result, the rotational axis of the rear wheel 13 is vertical. The attitude changes as it approaches. Conversely, when the adjustment screw 25 is operated from the state shown in FIG. 4 to lower the top plate 28 of the upper member 19, the front end 45 of the board 11 shown in FIG. 4 is displaced downward, and as a result the rear wheel 13 The rotation axis 43 of the above changes from the vertical direction to a posture in which it tilts further to the front side.

  By rotating the steering wheel 14 by 180 degrees around the rotation axis 16, a position 37 at which the wheel 32 of the front wheel 12 contacts the road surface 22 and a front side 38 of the position 38 where the rotation axis 16 of the steering wheel 14 intersects the road surface 22 ( 3 and 4) and the rear side (FIG. 5), the height of the front end 45 of the board 11 from the road surface 22 is also changed, and the inclination angle of the rotation axis 43 of the rear wheel 13 is changed. Can change. Specifically, as shown in FIG. 3 and FIG. 4, the position 37 where the wheel 32 of the front wheel 12 contacts the road surface 22 is on the front side of the position 38 where the rotation axis 16 of the steering wheel 14 intersects the road surface 22. In this case, the front end 45 of the board 11 is at a relatively low position, and the rotation axis 43 of the rear wheel 13 is in a posture of lying to the front. On the other hand, as shown in FIG. 5, when the position 37 where the wheels 32 of the front wheels 12 contact the road surface 22 is behind the position 38 where the rotation axis 16 of the steering wheel 14 intersects the road surface 22 The front end portion 45 of 11 is at a relatively high position, and the rotation axis 43 of the rear wheel 13 is in a posture of rising to the rear side.

  By turning the steering wheel 14 180 degrees around the rotation axis 16 and changing the position 37 at which the wheel 32 of the front wheel 12 contacts the road surface 22, the turning property of the front wheel 12 itself changes. That is, as shown in FIG. 3 and FIG. 4, when the position 37 where the wheel 32 of the front wheel 12 contacts the road surface 22 is on the front side of the position 38 where the rotation axis 16 of the steering wheel 14 intersects the road surface 22, The turnability of the steering wheel 14, that is, the turnability of the front wheel 12 is better than in the rear side. In addition, in this case, as described above, the turnability of the rear wheel 13 also becomes good, and as a result, the turnability of the kick scooter can be made better than in the case shown in FIG. Conversely, as shown in FIG. 5, if the position 37 where the wheels 32 of the front wheels 12 contact the road surface 22 is behind the position 38 where the rotation axis 16 of the steering wheel 14 intersects the road surface 22, this is The turnability of the steering wheel 14, that is, the turnability of the front wheel 12 becomes worse than when it is on the front side of the wheel. However, on the contrary, the straight stability of the kick scooter is improved. In addition, in this case, as described above, the rectilinearity of the rear wheel 13 is also improved, and as a result, the rectilinear travelability of the kick scooter can be improved as compared with the case shown in FIGS.

  In the case of the configuration shown in FIG. 6 as well, by changing the inclination angle of the rotation axis 43 for swinging the rear wheel 13 constituted by the swing caster as described above, the turnability of the kick scooter is obtained. It can be changed.

  Although some specific examples of the present invention have been described above, the present invention is not limited to the above specific examples. That is, in the technical idea of the present invention, if the rear wheel is swingable around the axis center that inclines forward and has a means to change the angle of the axis that inclines forward ast It is enough. The specific configuration is optional, and those skilled in the art can design and change various configurations as appropriate. For example, a plurality of the above-described means may be arbitrarily combined.
