It is coupled to the means 31.

따라서 보드(10,10a)가 좌우로 롤링될 경우에 회전부(30)가 보드(10,10a)의 하단에 형성된 수용부(40)에 좌우유동이 불가능하게 수용된 상태이기 때문에 전후보드(10,10a)의 롤링시 회전축이 그 양단에 돌출되게 형성된 돌출핀(36)이 탄성체(35)에 내입되어져 있고 탄성체(35)는 회전부(30)의 내공간(34)에 내입되어져 있어 전후보드가 연결축이 탄성체에 의하여 지지되어짐으로 직립이 용이하게 되는 것이고, 보드를 롤링토록 하면 캐스터의 요동에 의하여 추진력이 발생되는 것이고, 이러한 추진력은 회전축을 회전되어지게 함으로서 안정적인 롤링이 이루어지게 되는 것이다.Accordingly, when the boards 10 and 10a are rolled left and right, the front and rear boards 10 and 10a are not allowed to flow left and right in the receiving part 40 formed at the lower end of the boards 10 and 10a. ), A protruding pin 36 is formed in the elastic body 35 and the elastic body 35 is embedded in the inner space 34 of the rotating part 30. The upright is supported by this elastic body, and the upright is easily rolled. When the board is rolled, propulsion force is generated by the swing of the caster, and the propulsion force is made to be stable by rotating the rotating shaft.

또한 상기한 보드를 보관이나 휴대의 편의성을 위하여 보드를 접고하 할 경우에 연결축(20)의 중앙에 형성된 조작레바(50)를 일방향으로 회전토록 하면 도4에 도시된 바와 같이 조작레바(50)와 맞물려 있는 가이드판(23)이 동일하게 이동(회전)하게 되면서 상기 가이드판(23)의 일방향으로 경사진 가이드홀(24)에 끼워진 가이드핀(25)은 피스톤(22)이 일단에 형성된 핀고정홀(22a)에 고정되어 있어 가이드홀(24)의 경사각에 의하여 피스톤(22)이 실린더(21)내에서 도4에 도시된 바와 같이 빠져나가거나 들어오게 되는 것이다.In addition, when the board is folded and folded for convenience of storage or portability, when the operation lever 50 formed at the center of the connecting shaft 20 is rotated in one direction, the operation lever 50 as shown in FIG. ) Guide pins 23 engaged with the guide plate 23 is moved (rotated) in the same manner, the guide pin 25 is fitted into the guide hole 24 inclined in one direction of the guide plate 23 has a piston 22 is formed at one end The piston 22 is fixed to the pin fixing hole 22a so that the piston 22 exits or enters the cylinder 21 as shown in FIG. 4 by the inclination angle of the guide hole 24.

또한 상기 조작레바(50)가 조립된 상태에서 연결축(20)의 양단으로는 도9및 도11및 도12에 도시된 바와 같이 그 외측을 감싸면서 장착되어진 상기 회전부(30)는 수용부(40)에서 회전가능하게 원통형으로 이루어지고, 도7에 도시된 바와 같이 상기 회전부(30)가 회전되어질 수 있게 감싸게 되는 동일한 형태로 이루어진 전후보드의 수용부(40)에 수용되어지고 상기 수용부(40)의 후방에는 실린더(21)를 출입되어지는 피스톤(22)이 끼워지거나 빠짐되어질수 있도록 관통홀(43)이 형성되는 것이다.In addition, both ends of the connecting shaft 20 in the state in which the operating lever 50 is assembled, as shown in FIGS. 9, 11, and 12, are mounted to surround the outer portion 30 of the receiving portion ( 40 is rotatably cylindrical and is accommodated in the accommodating part 40 of the front and rear boards having the same shape as the rotating part 30 is wrapped to be rotated as shown in FIG. At the rear of the 40, the through hole 43 is formed so that the piston 22 which enters and exits the cylinder 21 can be fitted or removed.

이때 수용부(40)에는 만곡안착면(44)이 형성되어져 회전부(30)의 원활한 회전을 유도하게 되는 것이고, 수용부(40)의 전단으로는 받침부(46)를 형성하여 전후보드(10,10a)의 사용시에 연결축(20)에 강한 지지력을 갖게 되는 것이다.
따라서 피스톤(22)이 관통홀(43)을 출입하면서 회전부(30)가 수용부(40)내에서 회전되면서 보드(10,10a)가 접어지게 되거나 펼쳐짐이 유지되면서 보관이나 휴대가 가능토록 되는 것이다.At this time, the curved seating surface 44 is formed in the receiving part 40 to induce smooth rotation of the rotating part 30, and the front and rear boards 10 by forming the supporting part 46 at the front end of the receiving part 40. When the use of, 10a) will have a strong bearing force on the connecting shaft (20).
Therefore, as the piston 22 moves in and out of the through hole 43, the rotating part 30 is rotated in the receiving part 40 so that the boards 10 and 10a can be folded or unfolded while being stored or carried. .

또한 수용부(40)에 형성된 관통홀(43)은 피스톤(22)이 출입되어지면서 회전부(30)의 회전을 단속할 경우에 받은 많은 하중에 견딜 수 있도록 수용부(40)의 덮개(42)는 수용부(40)의 격벽(41)을 감싸는 형태로 결합되고 덮개(42)의 후방으로는 피스톤 출입구(48a)를 갖는 경사보강부(48)가 형성되며 상기 덮개(42)로 덮여지는 수용부(40)의 격벽(41)의 후방으로는 철판을 사용하여 관통홀(43a)을 갖는 보강판(47)을 형성토록 할수 있는 것이다.
이때 보강판(47)은 보드(10,10a)의 하단면에 형성된 내입홈(12)에 내입토록 함으로서 강한 지지력을 갖는 함을 받도록 한 것이다.
따라서 보관이나 휴대시에는 조작레바(50)를 정방향을 회전시키면 조작레바(50)와 고정핀(53)에 의하여 고정된 가이드판(23)이 회전되면서 가이드홀(24)에 끼워진 가이드핀(25)이 피스톤(22)의 핀고정홀(22a)과 연결되어있어 가이드핀(25)에 오무라들면서 외측으로 돌출되어진 피스톤(22)이 동시에 후진하면서 수용부(40)의 관통홀(43,43a)에서 빠져나가게 됨으로 연결축(20)의 회전부(30)는 수용부(40)에서 회전이 되면서 접어지게 되는 것이고, 반대로 사용을 위하여 펼치고자 할 경우에는 조작레바(50)를 역회전하면 반대로 작동되면서 관통홀(43,43a)에 피스톤(22)이 끼워지면서 회전부(30)는 수용부(40)에서 회전되지 않게 됨으로 보드(10,10a)의 좌우롤링에 의하여 연결축(30)의 양단에 형성된 돌출핀(36)이 회전부(30)의 내공간(34)에 수납된 탄성체(35)에 의하여 지지력을 받게 되면서 안정적인 직립이 가능하게 되고, 동시에 회전축(20)에 회전력을 부여하게 됨으로 캐스터에 의한 추진력을 물론 탄성체의 반발력에 의하여도 추진력을 얻게 되는 것이고, 이때에는 회전부(30)의 내공간에 수용되어진 탄성체가 강한 힘이 아닐 경우에도 좌우로의 탄력이 발생됨으로 작은 힘으로도 롤링이 가능하게 되는 것이다.In addition, the through hole 43 formed in the accommodating part 40 has a cover 42 of the accommodating part 40 so that the piston 22 can withstand a large load received when the rotation of the rotating part 30 is interrupted. Is coupled to surround the partition 41 of the receiving portion 40, the rear of the cover 42 is formed with an inclined reinforcement portion 48 having a piston entrance (48a) is accommodated by the cover 42 Behind the partition 41 of the part 40, it is possible to form a reinforcing plate 47 having a through hole 43a using an iron plate.
