  • the user can separately drive the front board and the rear board using the supporting means, and even the beginner can easily keep balance since he or she can drive the skate board through a bearing force provided by the supporting means.
  • the present invention can easily rotate even at a steep curve area due to its small radius of rotation, and is convenient to carry since it is foldable.
  • FIG. 1 is a perspective view of a skate board according to a preferred embodiment of the present invention.
  • FIG. 2 is an exploded perspective view of a central connection part of the present invention
  • FIG. 3 is a perspective view showing an operation of the central connection part when the skate board of the present invention is folded;

  • FIG. 5 is a perspective view of a skate board according to another preferred embodiment of the present invention.
  • FIG. 6 is a perspective view of a conventional skate board
  • FIG. 7 is a perspective view of an improved skate board of the skate board of FIG.
  • FIG. 1 is a perspective view of a skate board according to a preferred embodiment of the present invention
  • FIG. 2 is an exploded perspective view of a central connection part of the present invention.
  • the skate board according to the present invention includes a front board 11 having a caster 10 mounted on the underside thereof, a rear board 12 having a caster 10 mounted on the underside thereof, connecting means 20 for connecting the front board 11 and the rear board 12 with each other, and supporting means 30 coupled to the connecting means 20.
  • the casters 10 are mounted on the boards 11 and 12 in such a way as to be freely rotate on a rotational axis, and are partially disposed by the external force applied to the boards 11 and 12 so that the boards 11 and 12 can be moved forward or change the direction.
  • the connecting means 20 includes a central connection part 40 and board connection parts 22 mounted to both ends of the central connection part 40 and respectively coupled with shaft holes of the front board 11 and the rear board 12. It is preferable that the board connection parts are bearing-coupled to the central connection part 40 and the boards 11 and 12 in such a way as to be idly rotated. As described above, since the board connection parts 22 are mounted at both ends of the central connection part 40, a user can control the board connection part 22 only by the movement of one foot which steps on the board. Therefore, the present invention can easily rotate even at a steep curve area since the radius of rotation is short due to a short rotational axis during the rotation.
  • the board connection parts 22 are made of material capable of elastically restoring, so that the board connection parts 22 are distorted by their elasticity when the user applies the external force by the user's foot movement, and thereby, the casters 10 mounted on the underside of the boards 11 and 12 are partially disposed. As a result, the skate board according to the present invention can advance forward or change its direction.
  • the supporting means 30 is coupled with the central connection part 40, so that the user can separately drive the front board 11 and the rear board 12 by twisting the supporting means 30 to the right or left and easily keep the balance during traveling.
  • the boards 11 and 12 can be more effectively driven.
  • the central connection part 40 includes a front board connector
  • the front board connector 41 connected to the front board 11 and a rear board connector 42 connected to the rear board 12, and is in the form of a cylinder by coupling the front board connector 41 and the rear board connector 42 with each other.
  • the front board connector 41 and the rear board connector 42 respectively have semi-circular holes formed at the center thereof, and a hollow hole 43 for inserting the supporting means 30 thereinto is formed by coupling the semi-circular holes with each other.
  • the supporting means 30 includes a retaining protrusion
  • the supporting means 30 is detachably mounted on the central connection part 40. Therefore, when the supporting means 30 is rotated in one direction after it is inserted into the hollow hole 43, the supporting means 30 can be easily combined with the board. As described above, since the supporting means 30 is detachably combined with the board, a beginner can keep balance using the supporting means 30. After that, when the user is skilled in keeping balance, the user can use the skate board after removing the supporting means 30 from the skate board.
  • FIG. 2 shows an example that the retaining protrusion 31a is formed on the supporting means 30 and the retaining groove 43a is formed on the hollow hole 43, but it is also possible that the retaining groove 43a is formed on the outer circumference of the supporting means 30 and the retaining protrusion 31a is formed on the inner circumference of the hollow hole 43.
  • Foldable means 50 for allowing folding of the board at the boundary surface is provided at a predetermined area of a boundary surface between the front board connector 41 and the rear board connector 42.
  • the foldable means 50 may be a hinge.
  • the central connection part 40 is provided with a through hole passing side surfaces of the front board connector 41 and the rear board connector 42, and fastening means 60 is mounted on the through hole.
  • the fastening means 60 includes a fixed shaft 61 coupled with the through hole, a handle part 62 mounted at an end of the fixed shaft 61, and fixing means 63 mounted at the other end of the fixed shaft 61. It is referable that the fixing means 63 is a nut which will be fit into the shaft.

  • the fixed shaft 61 is moved downwardly from a U-shaped groove 45 formed on the rear board connector 42, and thereby, the coupling between the front board connection 41 and the rear board connector 42 is released.
  • the U-shaped groove 45 is formed on the rear board connector 42, but can be formed on the front board connector 41.
  • the board is folded at the boundary surface.
  • the skate board is folded at the boundary surface without forming any interval at the upper surfaces of the front board connector 41 and the rear board connector 42.
  • FIG. 5 is a perspective view of a skate board according to another preferred embodiment of the present invention.
  • the skate board according to the present invention further includes a connection board 13 connected to the rear board 12.
