This rod 2
The angle of the wheel mounting member 24 with respect to the board main body 1, that is, the mounting height of the wheel 23 with respect to the board main body 1 can be adjusted by pulling or pushing the 8 from the other end side. More specifically, a recess 30 is formed on the back surface of the board body 1 over the entire length in the front-rear direction, and a seat 31 is fixed in the recess 30 near the rear end of the board body 1 by welding or the like. The front surface of the rubber elastic body 32 is applied to the rear surface of the
2, a pressing plate 33 is applied to the rear surface, and the other end of the rod 28 is connected to a hole 33 a of the pressing plate 33, a rubber elastic body 32.
The rod 28 is inserted into the hole 32a of the receiving seat 31 and the rear surface of the holding plate 33 in a state of being inserted through the hole 31a of the receiving seat 31.
Nuts 34 and 3
5 is screwed in, the nuts 34 and 35 are tightened so as to sandwich the rubber elastic body 32, thereby fixing the angle of the wheel mounting member 24 with respect to the board body 1 and as a suspension of the rubber elastic body 32. It adjusts the power. In addition, two washers 36 are provided between the nut 34 and the seat 31 to prevent loosening.
37 are interposed. By the way, a shaft 27 for pivotally connecting the wheel mounting member 24 to the bracket 26 is provided.
The hole 26 of the bracket 26
a head 27a having a diameter larger than a, the head 27a is in contact with one of the brackets 26, and a female screw hole 27b is formed in the other end of the shaft 27, and a bolt screwed into the female screw hole 27b. The head 38a of 38 is in contact with the other bracket 26 side. 24a is a hole for inserting a shaft 27 formed at the lower end of the front end of the wheel mounting member 24 for connection with the pair of left and right brackets 26, and 24b is a wheel mounting member for connecting with the rod 28. 2
4 is a hole for inserting a shaft 29 formed in a pair of left and right plate portions 24c at the upper end of the front end portion. The lower end of the front end of the wheel mounting member 24 is sandwiched between a pair of left and right brackets 26 and pivotally connected by a shaft 27. The rod 28 is connected to a pair of left and right plate portions 2 at the upper end of the front end of the wheel mounting member 24.
4c and is pivotally connected by a shaft 29. The rear end-side wheel 23 supported by the wheel mounting member 24 mounted on the rear end of the board body 1 as described above
A cover-like brake plate 39 is mounted on the wheel mounting member 24 so as to cover the upper side of the wheel. The brake plate 39 is urged by a spring (not shown) in a direction slightly rising from the upper end of the rear end side wheel 23, and the upper end of the rear end side wheel 23 is pressed by stepping on the brake plate 39. Hold down the brakes.

In the above configuration, the front end side wheel 5
Is rotatably mounted on a bracket 10 elastically supported by a coil spring 15 with respect to the front fork 6, and a wheel 23 on the rear end side is a rubber elastic body 32 with respect to the board body 1. Is rotatably mounted on the wheel mounting member 24 elastically supported via the coil spring 15 so that the impact transmitted to the wheel 5 on the front end side even when the ground 40 which is the running surface has irregularities is transmitted by the coil spring 15. At the same time, the impact transmitted to the wheel 23 on the rear end side is reduced by the rubber elastic body 32, so that the running stability can be improved. In particular, the rubber elastic body 32 that reduces the impact transmitted to the rear end side wheel 23 can adjust the force as a suspension by the tightening force of the nuts 34 and 35, and can adjust the elastic force to a desired elastic force. Also, a wheel mounting member 24 for mounting the rear end side wheel 23 is provided.
Are nuts 34 so as to sandwich the rubber elastic body 32.
By tightening and 35, the mounting angle with respect to the board body 1 can be adjusted. Board body 1
By adjusting the mounting angle with respect to, for example,
It is possible to make the board body 1 horizontal as shown in FIG. 5, or to make the rear end side of the board body 1 higher as shown in FIG. When the board body 1 is in a horizontal state as shown in FIG. 5, the board can be used in a normal running state, and when the rear end of the board body 1 is raised as shown in FIG. Therefore, the running speed can be increased as compared with when the board body 1 is in the horizontal state, and the sportiness can be improved.

Further, in the folded state of the skateboard, the rubber ring 11 comes into contact with the upper end arcuate surfaces 19d of the pair of guide brackets 19, so that the handlebar 2 and the front end portion are folded in this folded state. The side wheel 5 and the like do not swing around the axis of the cylindrical portion 4 of the handlebar mounting member 3, and the folding posture is stabilized.

[0011]

As described above, according to the present invention, in a skateboard provided with running wheels at the front and rear ends of the board body, the angle of the wheel mounting member on the rear end portion with respect to the board body can be adjusted. This makes it possible to adjust the height of the rear end of the board body, which makes it possible to change the way of riding, and adjusts the tightening of the elastic body to reduce the impact transmitted to the wheel on the rear end side It is also possible to adjust the suspension to the desired elastic force.
