Description

Skateboards {skate board}

The present invention relates to a skateboard, and more particularly relates to a skateboard of a new structure that can easily change the direction, as well as excellent ride comfort, and can easily improve the driving force and excellent driving feeling.

In general, a skateboard consists of a long plate-shaped plate and wheels provided in front and rear of the bottom of the plate, and the skateboard is used by the user with one foot on the plate and kicking the skateboard with the other foot. When the driving direction is changed, the user changes the direction by moving the center of gravity of the body in the progress direction while tilting the plate with the foot in the advancing direction.

However, in the conventional skateboard, in order to change the direction to one side while driving, the user must tilt the plate in the advancing direction and move the center of gravity of the body in the advancing direction, and then to change the direction to the other side as described above. In addition, since the plate should be inclined in the other direction and at the same time, the weight of the core should be moved. In the case of a beginner, it is difficult to change the direction as well as falling off the plate easily. In addition, in order to propel the skateboard, the user must repeatedly improve the propulsion while kicking the ground, that is, it stops by pushing the ground with the other foot while placing one foot on the plate, which is inconvenient to use and decreases the driving feeling. There is this.

Therefore, the present invention is proposed to solve the fundamental problems of the prior art as described above, the object of the present invention is to divide the front and rear plates and connect the front and rear plates with an elastic body, the front and rear plates are twisted in opposite directions By bent in all directions, it is possible to provide a new skateboard structure that is easy to change direction and improve the driving force.

In addition, the wheels 20 provided on the rear plate 200 are disposed in a triangular shape. That is, one is provided in the center at the front side of the rear plate 200 and two are provided at the rear to be spaced apart by a predetermined interval in the width direction. At this time, the wheels (10, 20) may use a wheel that can change the direction freely. Meanwhile, in the illustrated embodiment, the wheels 20 of the rear plate 200 are arranged in a triangular shape, but in some cases, at predetermined intervals along the length direction to line up with the wheels 10 of the front plate 100. It can also install more than one.

The elastic body is to connect the front / rear plates (100,200), one embodiment of the present invention is made of a coil spring 300 that can be twisted or bent, the coil spring 300 is predetermined in the width direction of the skateboard Both ends are fixed to the front and rear plates 100 so as to be spaced apart from each other and parallel to each other. Therefore, it is possible to easily change the direction simply by rotating the front plate 100 in the advancing direction during the change of direction, it is returned to its original state by removing the force applied to the front plate (100). At this time, at both ends of the coil spring 300 is provided with a shaft diameter portion 310 is reduced at a predetermined interval to reduce the diameter, respectively, when fixed to the front / rear plates (100,200) by a fixing bracket 30 to be described later, It is configured to be firmly fixed without being separated in the axial direction in the rear plate (100,200). At this time, the protective tube 500 of the flexible rubber or synthetic resin material is fitted to the circumferential portion of the coil spring 300, it is possible to clean the appearance.

At this time, both ends of the coil spring 300 is firmly fixed to the front / rear plates (100, 200) by a fixing bracket (30). The fixing bracket 30 extends horizontally in the opposite direction from each other at an end of the locking portion 32 having a cross-shaped U-shape opening, and a flange portion 34 having a coupling hole at the center thereof. Is made of. Therefore, in the state in which the engaging portion 32 of the fixing bracket 30 is fitted to the shaft diameter portion 310 of the coil spring 300, a fixture such as a screw is used to pass through the through hole of the flange portion 34. It is fixed to the rear plate (100,200). Accordingly, the coil spring 300 is fixed to the front and rear plates 100 and 200 in a state where the fixing spring 30 is locked, thereby preventing the coil spring 30 from being separated in the axial direction. have.
