[Technical field to which the invention belongs]

 The present invention relates to a skateboard direction control structure, in particular, a bifurcated portion that forms an appropriate inclination at the front end of the deck board, a pedestal protruding here and a correspondence with a pivot connected to the front wheel, and furthermore, both sides of the pivot. With the stopper element fitted in the oblique conical shape and the springs at both ends, the pivot displaced by the inner hole can change the direction of the wheel from side to side only by moving the control rod lightly when turning the deck board. At this time, the elasticity formed by the compressed spring returns the front wheel automatically to the front direction, and the elasticity of the spring enables stable straight running, and is excellent in safety and easy in directional control. Related to the structure of board direction control.

[Prior art]

 Traditionally, skateboards have been widely used by many people because they have been used for sports and recreation or as a means of transportation, and because of their light structure.

[0003]

[Problems to be solved by the invention]

 However, conventional skateboards have a structure in which the traveling direction of the deck board can be mainly controlled by the steering wheel, and the steering wheel must be provided at an appropriate position to change the direction. In addition, the conventional skateboard is expensive due to the complicated structure of the handle, and the height must be adjusted by the user. For this reason, conventional skateboards are hardly practical.

[0004] Therefore, the steering wheel is replaced with a control rod, and a steel material having flexibility is used, and the wheel is automatically regenerated by its elasticity (that is, the turning force is released and the steel material is not compressed). Skateboards have been devised. For a skateboard with such a control rod structure, the force required for turning must be greater than the drag of steel. In addition, the greater the degree of change in direction, the greater the amount of force required for control.

[0005] Furthermore, different operation methods must be performed depending on the hardness of the steel material. That is, when the steel material is soft, it is necessary to reduce the operation force, and when the steel material is slightly hard, it is necessary to apply enough force to the operation. In addition, if the steel material is soft, it swings in response to the vibration of the deck board, and sways so much that it can no longer control straight running. With such a structure, not only is there a sense of danger to use, but there is also a risk of accidents due to inability to control the direction of travel.

[0006] In order to solve the above-mentioned problems, an object of the present invention is to provide a structure of a skateboard direction control that can easily perform stable traveling and direction change.

[0007]

[Means for Solving the Problems]

 A control rod is provided at the front end of the top surface of the deck board, and a rear wheel is mounted on the rear end of the bottom surface of the deck board.The inner hole of the support that protrudes from the front end of the deck board and below the fork is connected to the front wheel. The other end of the front wheel is pivoted at the fork, the pivot extends obliquely on both sides, and the spacer, fitting, ring, spring and both ends of the spring Toppers are provided, these are fitted with the pivots, and when the control rod is moved, the bifurcated part shifts, and the traction force with an appropriate inclination angle of the bifurcated part causes the pivot to shift in the inner hole. Therefore, the front wheel connected to the pivot changes direction, and at this time, the spring in the direction of the change is in a compressed state, and when the control rod is released, the force that was previously compressed and deformed is released. To adjust the resilience of the pivot The front wheel on the side is returned to the front direction, is locked by the uniform elasticity of the springs on both sides, performs stable straight running, and can easily change direction due to its elasticity. By installing the ring so that it can be adjusted and adjusting the looseness of the fitting, it is possible to control the retraction force that occurs when the pivot shifts.A thread is provided at the end of the pivot, and a stopper is provided here. It is also possible to adjust the tension of the spring by forming a stopper screw by adjusting the screw position, and furthermore, the fitting body is any elastic element. I do.

[Embodiment of the invention]

 Hereinafter, an embodiment of a skateboard direction control structure according to the present invention will be described with reference to FIGS. 1 to 7.

As shown in FIGS. 1 and 2, the skateboard includes a deck board 2 having a control rod 21 provided at a front end thereof and a rear wheel 22 pivotally mounted at a rear end of a bottom surface. A support base 24 protrudes from the bottom of the bifurcations 23, 23 at the front end of the deck board 2. The pivot 3 of the front wheel 25 passes through the inner hole 241. The opposite end of the front wheel 25 is pivotally connected to the forked portion 23, and both sides of the pivot 3 are formed as oblique cones 31. The spacer 4, the fitting 5, the ring 6, the spring S, and the stoppers 7 at both ends of the spring S, which are installed on the side of the support base 24, are firmly fitted to the pivot 3 (state after assembly). Is shown in FIG. 2). Further, the inclination angle of the forked portion 23 is designed so that the front wheel 25 and the ground form an optimum angle, whereby the direction of the front wheel 25 of the deck board 2 is easily changed.

As shown in FIG. 4, when the control rod 21 is moved rightward as indicated by P 1, the forked portion 23 shifts with the control rod 21. As a result, the pivot 3 shifts to the left in the inner hole 241 and the front wheel 25 turns to the right due to an appropriate traction force of the inclination angle θ formed by the forked portion 23. At this time, as shown in FIGS. 4 and 5, the spring S in the bending direction is in a compressed state. At the same time, the deck board 2 forms a slope that overcomes the centrifugal force, so that the human body and the vehicle body can run integrally.

As shown in FIG. 6, when the control rod 21 is moved to the left as indicated by P 2, the forked part 23 is shifted with the control rod 21. As a result, the pivot 3 is shifted rightward in the inner hole 241 by the traction force of the forked portion 23, and the front wheel 25 is turned leftward. At this time, as shown in FIGS. 6 and 7, the spring S in the bending direction is in a compressed state. At the same time, the deck board 2 forms a slope that overcomes the centrifugal force, so that the human body and the vehicle body can run integrally as described above.

When the force P1 or P2 applied to the control rod 21 is released, the compressed spring S in both the left and right directions releases the previously compressed force, and the elastic force generated by the pivot 3 is released. Control. Further, as shown in FIG. 3, when the left and right front wheels 25 are returned to the linear direction, the springs S on both sides lock the front wheels 25 with uniform elasticity, and perform a stable linear progression. In addition, when the direction is changed, the retraction capability of the pivot 3 becomes smaller as the displacement of the pivot 3 becomes larger due to the elasticity of the spring S and the oblique cone 31 on both sides of the pivot 3, so that the control can be performed easily.

Further, a screw thread may be provided at the end of the pivot 3 of the skateboard, and a stopper 7 may be fixed to the screw thread to adjust the looseness depending on the screwing position.

[0014]

[Effect of the invention]

 According to the present invention, the special structure of the pivot makes it easy to control the direction change, and furthermore, the springs on both sides lock the front wheel with uniform elasticity to stabilize the progression of the skateboard. Can provide control structure.
