이러한 발판프레임(41)은 틸팅본체(20)가 측방으로 기울어질수록 일단 쪽이 상방으로 회전하기 때문에 발 앞부분이 들리게 되어 발목이 꺽이는 불편한 자세가 된다. 따라서 틸팅본체(20)가 측방으로 기울어질 때 발목이 꺽이지 않게 하기 위해 발판프레임(41) 일단 양쪽은 바깥쪽을 향해 돌출되게 구성되고, 돌출된 부위는 봉 형상으로 구성되어 돌출된 부위에 발을 얹을 수 있게 구성되거나, 상기 돌출된 부위는 축 형상으로 구성되고, 축 부위에 후술하는 발판(42)을 끼움 결합시켜 발판(42)에 발을 얹을 수 있게 구성된다.In this footrest frame 41, as the tilting body 20 is inclined to the side, one side rotates upward, so that the front of the foot is lifted and the ankle is bent. Therefore, in order to prevent the ankle from bending when the tilting body 20 is inclined laterally, one end of the scaffolding frame 41 is configured to protrude outward, and the protruding part is formed in a rod shape, so that the foot It is configured to be able to put on, or the protruding portion is configured in a axial shape, and a footrest 42, which will be described later, is fitted to the shaft portion so that the foot can be placed on the footboard 42.
발판프레임(41) 일단 형상에 대한 또 다른 실시예로, 도 1에서 b와 같이 발판프레임(41)은 일단 상부에 좌우측으로 넓고 두꺼운 판이 결합되고, 제1륜(14) 쪽에 위치한 모서리 부위가 둥글게 구성될 수 있다. 그리고 발판프레임(41) 일단 부위가 상방으로 회전될 때 탑승자 발이 둥근 모서리 부위에 접촉되게 함으로써, 틸팅본체(20)가 측방으로 기울어질 때 발목이 꺽이지 않게 구성될 수 있다.

In addition, the footrest frame 41 may be configured so that the ankle does not break when the tilting body 20 is inclined laterally by allowing the occupant's feet to contact the rounded corners when the portion is rotated upward.
발판프레임(41) 일단 형상에 대한 또 다른 실시예로, 도 1에서 c와 같이 발판프레임(41) 일단 상부에 좌우측으로 넓고 두꺼운 판이 결합되고 판 상부를 둥글게 구성하여 둥글게 구성된 부위에 발을 얹을 수 있게 구성된다. 그리고 발판프레임(41) 일단이 상방으로 회전될 때 둥근 부위를 따라 발이 접촉되게 하여 틸팅본체(20)가 측방으로 기울어질 때 발목이 꺾이지 않게 구성될 수 있다.As another embodiment of the shape of one end of the scaffolding frame 41, as shown in FIG. 1 c, a wide and thick plate is coupled to the left and right to the top of one end of the scaffolding frame 41, and the upper part of the scaffolding is rounded so that the foot can be placed on a part configured to be round. It is structured. In addition, when one end of the footrest frame 41 is rotated upward, the foot may be in contact along the rounded portion so that the ankle is not bent when the tilting body 20 is inclined laterally.
발판프레임(41) 타단은 지지본체(30) 방향으로 연장되게 구성되고, 발판프레임(41) 타단 부위 양쪽에 후술하는 연결부재(61)를 묶을 수 있게 홈이 구비된다.

In an embodiment of the present invention, the scaffolding 42 is fitted in a shaft portion protruding outward from both sides of the scaffolding frame 41 so that the front and rear can be rotated vertically. And it is configured to be located between a pair of straight extension lines (x) to be described later, so that the tilting body 20 can be prevented from tilting laterally by the weight of the occupant's feet and legs even if the occupant sits on the saddle and puts his feet on the footrest 42. It is structured.
물론, 발판(42)이 구비 안 될 수도 있음으로 발판(42)은 본 발명의 권리 범위에 제한되지 않는다.Of course, as the footrest 42 may not be provided, the footrest 42 is not limited to the scope of the present invention.
본 발명의 실시예에서, 틸팅억제부(60)는 발판프레임(41) 타단 또는 중간 부위가 지지프레임(31)에 연결되게 하거나 걸리게 하는 구성이다.In an embodiment of the present invention, the tilting inhibiting unit 60 is configured to allow the other end or the intermediate portion of the scaffolding frame 41 to be connected to or caught on the support frame 31.
상기 틸팅억제부(60)는 발판프레임(41) 타단 또는 중간 부위가 지지프레임(31)에 걸리게 하여 발판프레임(41) 일단이 일정 높이 밑으로 내려가지 않게 하면서 틸팅본체(20)가 좌측 또는 우측으로 기울어질 때 발판프레임(41) 일단이 회전중심축(p)으로부터 멀어지게 한다.The tilting restraining unit 60 makes the other end or the middle of the scaffolding frame 41 catch on the support frame 31 so that one end of the scaffolding frame 41 does not fall below a certain height, while the tilting body 20 is left or right When inclined to the footrest frame 41, one end is away from the rotation center axis (p).
본 발명의 제1실시예에서, 틸팅억제부(60)는 연결부재(61)로 구성된다.In the first embodiment of the present invention, the tilting inhibiting unit 60 is composed of a connecting member 61.
도 2를 참조하면, 연결부재(61)는 한 쌍으로 구성되고, 각각의 연결부재(61)는 발판프레임(41) 타단 양쪽에 구비된 홈에 일단이 결합되고, 타단은 연결부재(61) 일단이 결합된 부위에서 수직 하방에 위치하면서 회전중심축(p)과 비슷한 높이에 위치한 지지바(33) 부위에 결합된다.2, the connecting member 61 is composed of a pair, each connecting member 61 has one end coupled to the groove provided on both sides of the other end of the scaffolding frame 41, the other end is the connecting member 61 One end is located vertically downward from the combined portion and is coupled to a portion of the support bar (33) located at a height similar to the rotation center axis (p).
물론, 연결부재(61) 일단과 타단 결합 지점을 회전중심축(p) 좌우측에 위치하게 구성하고, 틸팅본체(20)가 기울어질수록 틸팅본체(20)가 기울어진 쪽에 위치한 발판프레임(41) 부위에 연결된 연결부재(61)는 인장력이 걸리고, 반대쪽에 연결된 연결부재(61)는 휘어지게 되는 위치인 지지프레임(31) 부위에 연결부재(61)가 결합될 수도 있지만 바람직하지 않다.Of course, the connecting member 61 is configured to be located on the left and right sides of the rotation center axis (p), and as the tilting body 20 is inclined, the footrest frame 41 located on the inclined side of the tilting body 20 The connecting member 61 connected to the portion takes a tensile force, and the connecting member 61 connected to the opposite side may be coupled to the support frame 31 portion, which is a position where the connecting member 61 is bent, but it is not preferable.
상기 연결부재(61)는 틸팅본체(20)가 좌측 또는 우측으로 기울어질 때 길이는 늘어나지 않으면서 발판프레임(41) 타단이 이동되는 방향에 따라 형상이 가변되는 부재로 구성될 수 있는데, 본 발명의 실시예에서 연결부재(61)는 다이니마 로프로 구성됨을 제시한다.The connecting member 61 may be composed of a member whose shape changes according to the direction in which the other end of the scaffolding frame 41 is moved without increasing its length when the tilting body 20 is inclined to the left or right. In the embodiment of the connection member 61 is proposed to be composed of a Dyneema rope.
상기 다이니마 로프는 비강도가 와이어보다 15배나 강하면서 섬유 특성인 유연성이 있기 때문에, 틸팅본체(20)가 틸팅시 발판프레임(41) 타단 부위가 이동하는 쪽으로 휘어지면서 발판프레임(41) 타단을 잡아주게 됨으로 발판(42)이 내려가지 않게 된다.Since the Dyneema rope is 15 times stronger than the wire and has flexibility, which is a fiber characteristic, the tilting body 20 is bent toward the movement of the other end of the scaffolding frame 41 while tilting the other end of the scaffolding frame 41. As it is held, the footrest 42 does not descend.
물론, 틸팅본체(20)가 틸팅시 발판프레임(41) 타단이 이동되는 방향 따라 이동하면서 발판(42)이 내려가지 않게 잡아줄 수 있는 부재면 어떤 부재든 연결부재(61)로 사용될 수 있다.Of course, any member may be used as the connecting member 61 as long as the tilting body 20 moves along the direction in which the other end of the scaffolding frame 41 moves while tilting and holds the scaffold 42 so that it does not descend.
다른 종류의 연결부재(61)에 대한 실시예를 들면, 도 2에서 c와 d같이 연결부재는(61) 타단이 지지바(33) 양 끝단에 각각 결합되고, 일단은 측방으로 회전 가능하게 구성되며, 일단 부위에 앞뒤로 관통된 구멍이 구비 되는 바 형상으로 구성될 수도 있다.For an example of another type of connecting member 61, the connecting member 61 has the other end coupled to both ends of the support bar 33 as shown in FIG. 2 c and d, and one end is configured to be rotatable laterally. It may be configured in a bar shape in which a hole penetrated back and forth at one end is provided.
즉, 연결부재(61)는 휘어지지 않는 바 형상으로 구성되고, 발판프레임(41) 타단 양쪽 부위가 양쪽 연결부재(61) 구멍에 끼움 결합되어 구멍 가장자리에 걸리게 구성된다. 그리고 틸팅본체(20)가 틸팅시 연결부재(61) 일단 부위는 연결부재(61) 타단이 결합된 지점을 회전축으로 발판프레임(41)과 같이 측방으로 회전하여 틸팅본체(20)가 기울어진 쪽에 위치한 발판프레임(41) 타단 부위는 연결부재(61) 구멍 가장자리에서 분리되고, 발판프레임(41) 타단 다른 쪽은 연결부재(61) 구멍 가장자리에 접촉상태로 유지되게 구성될 수도 있다.That is, the connecting member 61 is configured in a bar shape that does not bend, and both portions of the other ends of the scaffolding frame 41 are fitted into the holes of both connecting members 61 to be caught on the edge of the hole. And when the tilting body 20 is tilted, one end of the connection member 61 is rotated laterally like the scaffolding frame 41 by the rotation axis at the point where the other end of the connection member 61 is coupled, so that the tilting body 20 is inclined. The other end of the scaffolding frame 41 is separated from the edge of the hole of the connecting member 61, and the other end of the scaffolding frame 41 may be configured to remain in contact with the edge of the hole of the connecting member 61.
물론, 도 2에서 e와 f같이 연결부재(61)는 반대로 일단이 발판프레임(41) 타단 양쪽에 각각 결합되고, 타단은 측방으로 회전 가능하게 구성되며 타단 부위에 관통된 구멍이 구비될 수 있다. 그리고 상기 구멍에 지지프레임(31)이 끼움 결합되게 구성된다.Of course, as shown in FIG. 2 e and f, the connecting member 61 has one end coupled to both sides of the other end of the scaffolding frame 41, respectively, the other end is configured to be rotatable laterally, and a hole through the other end may be provided. . And the support frame 31 is configured to be fitted into the hole.
더 구체적으로 설명하면, 지지프레임(31)에는 양 측방으로 조금 연장된 후 후방으로 조금 연장된 지지바(33)가 구비되고, 후방으로 연장된 지지바(33) 부위가 연결부재(61) 구멍에 끼움 결합된다. 그리고 틸팅본체(20)가 틸팅되지 않은 상태에서는 양쪽 지지바(33)가 양쪽 연결부재(61) 구멍 가장자리에 접촉되게 구성되고, 틸팅본체(20)가 틸팅될 경우에는 틸팅본체(20)가 기울어진 반대쪽에 위치한 연결부재(61)는 지지바(33)에 접촉된 상태로 유지되며, 틸팅본체(20)가 기울어진 쪽에 위치한 연결부재(61)는 지지바(33)로부터 떨어지게 구성될 수도 있다.More specifically, the support frame 31 is provided with a support bar 33 slightly extended in both sides and then slightly extended rearward, and a portion of the support bar 33 extending rearward is a hole in the connection member 61 It is fitted in and combined. And when the tilting body 20 is not tilted, both support bars 33 are configured to be in contact with the edges of the holes of both connecting members 61, and when the tilting body 20 is tilted, the tilting body 20 is inclined. The connecting member 61 located on the opposite side is maintained in contact with the support bar 33, and the connecting member 61 located on the inclined side of the tilting body 20 may be configured to be separated from the support bar 33. .
연결부재(61)가 지지프레임(31)에 결합되는 위치는 틸팅본체(20)가 틸팅시 발판부(40) 동작에 영향을 미치므로 상기 연결부재(61)가 지지프레임(31)에 결합되는 구조에 대해 설명하면 다음과 같다.The position at which the connection member 61 is coupled to the support frame 31 affects the operation of the footrest unit 40 when the tilting body 20 is tilted, so that the connection member 61 is coupled to the support frame 31. The structure is as follows.
연결부재(61)가 지지프레임(31)에 결합된 지점이 회전중심축(p)에서 측방으로 멀어질수록 틸팅본체(20)가 틸팅시 발판부(40) 일단이 회전중심축(p)으로부터 멀어지는 폭이 커지고 후술하는 직선연장선(x) 폭도 커진다.As the point at which the connecting member 61 is coupled to the support frame 31 is further away from the rotational center axis p, the tilting body 20 is tilted, the footrest 40, one end of which is from the rotational center axis p. The distance away increases, and the width of the linear extension line (x) to be described later increases.
또한, 연결부재(61)가 지지프레임(31)에 결합된 지점이 회전중심축(p)과 같을 경우 틸팅본체(20)가 틸팅시 발판(42)을 누르면 틸팅본체(20)가 기울어지게 된다.In addition, when the connecting member 61 is coupled to the support frame 31 is the same as the rotation center axis p, the tilting body 20 is tilted when the tilting body 20 presses the foot plate 42 during tilting. .
본 발명의 실시예에서, 연결부재(61) 일단과 타단이 결합된 지점은 회전중심축(p)에서 같은 측방에 위치하되 틸팅본체(20)가 기울어질수록 기울어진 쪽에 위치한 연결부재(61)는 휘어지고, 반대쪽에 위치한 연결부재(61)가 당겨지는 위치가 되는 지지프레임(31) 부위에 연결부재(61)가 결합된다. 그리고 틸팅본체(20)가 기울어지지 않은 상태에서 양쪽 연결부재(61)에 인장력이 걸리게 구성함으로써, 틸팅본체(20)가 좌우측 중 어느 한쪽으로 기울어질 경우 기울어진 반대쪽에 위치한 연결부재(61)는 인장력이 걸리고, 기울어진 쪽에 위치한 연결부재(61)는 휘어지게 된다. In an embodiment of the present invention, the connection member 61 is located at the same side from the rotation center axis p, but the connecting member 61 is located on the inclined side as the tilting body 20 is inclined. Is bent, and the connecting member 61 is coupled to a portion of the support frame 31 at which the connecting member 61 located on the opposite side is pulled. And by configuring the tension force applied to both connecting members 61 in a state where the tilting body 20 is not inclined, when the tilting body 20 is inclined to one of the left and right sides, the connecting member 61 located on the opposite side inclined is Tensile force is applied, and the connecting member 61 located on the inclined side is bent.
여기서, 틸팅본체(20)가 기울어진 쪽에 위치한 발판(42)을 누르면 반대쪽에 위치한 발판프레임(41) 타단 부위가 연결부재(61)에 걸려 연결부재(61)에 걸린 지지본체(30) 부위를 상방으로 제껴는 구조가 되지만, 탑승자 체중 대부분이 안장(52)에 실리고, 틸팅본체(20)가 지지본체(30)를 누르는 구조가 됨으로 지지본체(30)는 측방으로 기울어지지 않게 된다.Here, when the tilting body 20 is pressed the footrest 42 located on the inclined side, the other end of the scaffolding frame 41 located on the opposite side is caught by the connecting member 61 and the support body 30 is caught by the connecting member 61. Although it is a structure to be removed upward, most of the weight of the occupant is carried on the saddle 52, and the support body 30 is not inclined laterally because the tilting body 20 has a structure that presses the support body 30.
상기와 같이 발판프레임(41) 타단이 지지프레임(31)에 걸리게 하여 발판(42)이 일정 높이 밑으로 회동 못하게 하면서 틸팅본체(20)가 좌측 또는 우측으로 기울어질 때 발판프레임(41) 일단 쪽이 회전중심축(p)으로부터 멀어지게 구성된다. As described above, the other end of the scaffolding frame 41 is caught by the support frame 31 so that the scaffolding 42 is not rotated below a certain height, and when the tilting body 20 is inclined to the left or right, one end of the scaffolding frame 41 It is configured to be away from the rotation center axis (p).
즉, 틸팅본체(20)가 좌측 또는 우측으로 기울어질 때 틸팅프레임(21)에 결합된 발판프레임(41) 중간 부위가 측방으로 기울어지기 때문에 발판프레임(41) 타단 부위 중 기울어진 반대쪽에 위치한 부위는 상방으로 이동되어야 하는데 연결부재(61)에 걸려 상방으로 이동 못하고 지지본체(30) 방향으로 회전하게 된다. 그리고 발판프레임(41) 타단이 지지본체(30) 방향으로 회전할 경우 기울어진 쪽에 위치한 연결부재(61)는 휘어지고. 발판프레임(41) 일단은 상방으로 회전하여 회전중심축(p)으로부터 멀어지는 쪽으로 이동된다. That is, when the tilting body 20 is inclined to the left or right, the middle portion of the scaffolding frame 41 coupled to the tilting frame 21 is inclined laterally, so the portion located on the opposite side of the other end of the scaffolding frame 41 Is to be moved upward, but is caught by the connecting member 61 and cannot move upward and rotates in the direction of the support body 30. And when the other end of the scaffolding frame 41 rotates in the direction of the support body 30, the connecting member 61 located on the inclined side is bent. One end of the scaffolding frame 41 rotates upward and moves away from the rotation center axis p.
틸팅본체(20)가 측방으로 기울어질수록 발판프레임(41) 일단이 회전중심축(p)으로부터 멀어지게 구성될 경우, 틸팅본체(20)가 측방으로 기울어질수록 틸팅본체(20)가 기울어진 반대쪽에 위치한 발판(42)은 상방으로 이동하면서 탑승자 하체를 상방으로 밀어 올리게 된다. 따라서 틸팅본체(20)가 측방으로 기울어지지 않을 경우, 발판(42)을 누르는 힘은 틸팅본체(20)가 측방으로 기울어짐을 억제시키는 쪽으로 작용하고, 틸팅본체(20)가 기울어질 경우, 발판(42)을 누르는 힘은 틸팅본체(20)가 세워지는 쪽으로 작용하게 된다. When the tilting body 20 is inclined laterally, the more the scaffolding frame 41 is configured to be farther away from the rotational center axis p, the more the tilting body 20 is inclined laterally, the more the tilting body 20 is tilted. The scaffold 42 located on the opposite side moves upward and pushes the passenger's lower body upward. Therefore, when the tilting body 20 is not inclined laterally, the force pressing the footboard 42 acts toward suppressing the tilting body 20 from tilting laterally, and when the tilting body 20 is inclined, the footrest ( The force pressing 42) acts on the side where the tilting body 20 is erected.
틸팅본체(20)가 측방으로 기울어질수록 발판부(40) 일단이 회전중심축(p)으로부터 안 멀어지게 구성될 경우, 발판(42)을 밟을 때 틸팅본체(20) 기울어짐을 억제하는 힘은 없다. When the tilting body 20 is inclined laterally, when the one end of the footrest 40 is configured to be farther away from the rotational center axis p, the force to suppress the tilting of the tilting body 20 when stepping on the footrest 42 is none.
도 3에서 a를 참조하면, 틸팅본체(20)가 측방으로 기울어지지 않은 상태를 평면도로 그렸을 때, 연결부재(61)가 지지프레임(31)에 결합된 부위와 앞뒤는 발판부(40)가 틸팅프레임(21)에 결합된 부위와 일치하고, 좌우는 회전중심축(p)과 일치하는 지점을 직선으로 그은 선이 발판부(40) 일단 쪽으로 연장된 직선(이하 직선연장선(x)이라고 함) 부위를 눌렸을 때 틸팅본체(20)가 좌우 어느 쪽으로도 기울어지지 않게 된다.Referring to a in FIG. 3, when the tilting body 20 is drawn in a plan view when the tilting body 20 is not inclined laterally, the portion where the connecting member 61 is coupled to the support frame 31 and the footrest portion 40 are A straight line extending toward one end of the scaffold 40 is a straight line that coincides with the part coupled to the tilting frame 21, and the left and right sides coincide with the rotation center axis (p) (hereinafter referred to as a straight extension line (x)). ) When the part is pressed, the tilting body 20 is not inclined in either side.
도 3에서 c를 참조하면, 발판부(40) 1부위를 누르면 발판부(40)가 틸팅프레임(21) 2부위를 누르게 되고, 발판부(40) 3부위를 누르면 발판부(40)가 틸팅프레임(21) 4부위를 누르게 되고, 발판부(40) 5부위를 누르면 발판부(40)가 틸팅프레임(21) 6부위를 누르게 된다. 그리고 발판부(40) 3부위를 누르면 틸팅본체(20)는 측방으로 기울어지지 않게 되고, 발판부(40) 1부위와 5부위를 누르면 발판부(40)가 회전중심축(p)에서 측방에 위치한 틸팅프레임(21) 부위를 누르게 됨으로 누른 방향 쪽으로 틸팅본체(20)가 기울어지게 된다. 따라서 직선연장선(x)은 발판부(40) 3지점과 발판부(40) 4지점을 그은 직선이 발판부 타단 쪽으로 연장된 직선이 된다.Referring to c in FIG. 3, when the first part of the scaffold 40 is pressed, the scaffold 40 presses the second part of the tilting frame 21, and the scaffold 40 tilts when the third part of the scaffold 40 is pressed. When pressing the 4 parts of the frame 21, and pressing the 5 parts of the scaffold 40, the scaffold 40 presses the 6 parts of the tilting frame 21. And when pressing the 3rd part of the scaffolding part 40, the tilting body 20 is not inclined laterally, and pressing the 1st part and 5th part of the scaffolding part 40 moves the scaffolding part 40 to the side from the rotation center axis (p). As the portion of the tilting frame 21 is pressed, the tilting body 20 is inclined toward the pressed direction. Therefore, the straight line extension line x is a straight line extending toward the other end of the scaffolding portion 40 and the four points of the scaffolding portion 40.
도 3에서 a와 같이 직선연장선(x)을 좌우 한 쌍이 되게 하고, 한 쌍의 직선연장선(x) 사이를 누르면 틸팅본체(20)는 좌우 어느 쪽으로도 기울어지지 않게 된다. 그리고 직선연장선(x) 바깥쪽을 누르면 누른 방향 쪽으로 틸팅본체(20)가 기울어지게 된다. In Fig. 3, as shown in a, the straight line extension line (x) becomes a pair of left and right, and the tilting body 20 is not inclined in either side of the left or right side by pressing between the pair of straight line extension lines (x). And when the outside of the straight extension line (x) is pressed, the tilting body 20 is inclined toward the pressed direction.
구체적으로 설명하면, 틸팅본체(20)가 좌측으로 기울어지든 우측으로 기울어지든 상관없이 한 쌍의 직선연장선(x) 사이에 위치한 부위는 직선연장선(x)을 기준으로 틸팅본체(20)가 기울어지는 반대쪽에 위치하게 된다. 따라서 틸팅본체(20)가 좌측으로 기울어지든 우측으로 기울어지든 상관없이 틸팅본체(20)가 기울어진 상태에서 한 쌍의 직선연장선(x) 사이에 위치한 발판부(40) 부위를 누르면 틸팅본체(20)는 세워지게 된다.Specifically, regardless of whether the tilting body 20 is inclined to the left or to the right, the portion located between the pair of straight extension lines (x) is the tilting body (20) inclined based on the straight extension line (x). It will be located on the other side. Therefore, regardless of whether the tilting body 20 is inclined to the left or to the right, when the tilting body 20 is inclined and pressing the portion of the footrest 40 located between a pair of straight extension lines (x), the tilting body 20 ) Is built.
즉, 한 쌍의 직선연장선(x) 사이에 탑승자 발이 위치하면, 틸팅본체(20)가 측방으로 기울어질 때 탑승자 하체를 상방으로 밀어 올리게 됨으로 한 쌍의 직선연장선(x) 사이를 누르는 탑승자 하체 무게는 기울어진 틸팅본체(20)가 원상복귀 되는 쪽으로 작용하고, 틸팅본체(20)가 기울어지지 않은 상태에서는 틸팅본체(20)가 기울어짐을 억제시키는 쪽으로 작용한다. That is, if the occupant's foot is located between a pair of straight extension lines (x), the weight of the occupant's lower body pressing between the pair of straight extension lines (x) is pushed up by pushing the occupant's lower body upward when the tilting body 20 is inclined to the side. Acts toward the inclined tilting body 20 is restored to its original state, and acts toward suppressing the tilting of the tilting body 20 when the tilting body 20 is not inclined.
틸팅본체(20)가 측방으로 기울어질 경우 틸팅본체(20)는 발판(42)을 누르는 힘의 방향이 틸팅본체(20)가 측방으로 기울어진 각도와 같아야 직선연장선(x)을 기준으로 발판(42)을 누른 방향 쪽으로 기울어진다. 그리고 코너 주행 중 틸팅본체(20)가 기울어질 경우, 발판(42)을 누르는 힘의 방향이 원심력 때문에 저절로 기울어지기 때문에 틸팅본체(20)가 기울어질 경우에도 직선연장선(x)을 기준으로 누른 발판(42) 쪽으로 틸팅본체(20)가 기울어진다.When the tilting body 20 is inclined to the side, the tilting body 20 must have the same direction as the angle at which the tilting body 20 is inclined laterally. 42) is tilted in the pressed direction. And when the tilting body 20 is inclined during corner driving, the direction of the force pressing the footboard 42 is inclined by itself due to the centrifugal force, so even when the tilting body 20 is inclined, the footboard pressed based on the straight extension line (x) The tilting body 20 is inclined toward (42).
직선연장선(x)은 도 3에서 b와 같이 발판프레임(41) 타단 부위가 지지프레임(31)에 걸릴 때 존재하고, 발판프레임(41) 타단 부위가 지지프레임(31)에 걸리지 않으면 존재하지 않는다. 따라서 연결부재(61)에 인장력이 걸릴 때만 직선연장선(x)이 존재한다.The straight extension line (x) exists when the other end of the scaffolding frame 41 is caught by the support frame 31 as shown in b in FIG. 3, and does not exist unless the other end of the scaffolding frame 41 is caught by the support frame 31. . Therefore, the linear extension line (x) exists only when a tensile force is applied to the connecting member 61.
한 쌍의 직선연장선(x) 사이 폭이 좁으면 직선연장선(x)은 발판부(40) 상에 위치하지만 한 쌍의 직선연장선(x) 사이 폭이 크면 직선연장선(x)은 발판부(40) 바깥쪽에 위치하게 된다.If the width between the pair of straight extension lines (x) is narrow, the straight extension line (x) is located on the scaffolding part 40, but if the width between the pair of straight extension lines (x) is large, the straight extension line (x) is the scaffolding part (40). ) It is located outside.
발판(42) 쪽에 위치한 한 쌍의 직선연장선(x) 사이 폭이 클수록 틸팅본체(20)가 기울어질 때 틸팅본체(20)가 세워지려고 하는 힘이 커지고, 틸팅본체(20)가 기울어지지 않은 상태에서는 안장에 실린 탑승자 체중을 좌우 어느 한쪽으로 많이 이동해야 틸팅본체(20)가 기울어지기 때문에 발판(42) 부위에 위치한 한 쌍의 직선연장선(x) 사이 폭이 크면 클수록 더 안정적으로 탑승할 수 있다.The larger the width between the pair of straight extension lines (x) located on the scaffold 42 side, the greater the force that the tilting body 20 tries to erect when the tilting body 20 is inclined, and the tilting body 20 is not inclined. In the case, the tilting body 20 is inclined only when the weight of the occupant carried on the saddle is moved to either right or left, so the larger the width between the pair of straight extension lines x located at the footrest 42, the more stable boarding can be. .
그리고 한 쌍의 직선연장선(x) 사이 폭이 커질수록 틸팅본체(20)가 틸팅할 때 발판부(40) 일단이 회전중심축(p)에서 멀어지는 폭이 커지므로 발판부(40) 일단이 회전중심축(p)으로부터 멀어지는 폭과 틸팅본체(20)가 세워지려고 하는 힘을 고려해서 한 쌍의 직선연장선(x) 사이 폭 크기를 정해야 된다.And as the width between a pair of straight extension lines (x) increases, when the tilting body (20) tilts, the width of one end of the scaffolding part 40 away from the rotational center axis (p) increases, so that one end of the scaffolding part 40 rotates. In consideration of the width away from the central axis (p) and the force at which the tilting body 20 is to be erected, the size of the width between the pair of straight extension lines (x) should be determined.
도 3에서 d를 참조하면, 발판(42) 쪽에 위치한 한 쌍의 직선연장선(x) 사이 폭 크기는 지지프레임(31)과 발판프레임(41)에 결합된 한 쌍의 연결부재(61) 사이 폭이 클수록 커지고, 틸팅프레임(21)에 결합된 발판프레임(41) 부위에서 연결부재(61))가 결합된 발판프레임(41) 부위까지 길이보다 틸팅프레임(21)에 결합된 발판프레임(41) 부위 또는 연결부재(61)가 결합된 발판프레임(41) 부위에서 발판(42)까지 길이가 더 길수록 커진다. 따라서 지지프레임(31)에 결합된 한 쌍의 연결부재(61) 사이 폭을 크게 하거나 연결부재(61)가 결합된 발판프레임(41) 부위에서 틸팅프레임(21)에 결합된 발판프레임(41) 부위까지 길이보다 틸팅프레임(21)에 결합된 발판프레임(41) 부위에서 발판(42)까지 길이를 더 길게 구성함으로서 한 쌍의 직선연장선(x) 사이 폭을 크게 할 수 있다.Referring to d in Figure 3, the width between the pair of straight extension lines (x) located on the side of the scaffold 42 is the width between the support frame 31 and the pair of connecting members 61 coupled to the scaffold frame 41 The larger this is, the scaffolding frame 41 coupled to the tilting frame 21 is greater than the length from the scaffolding frame 41 coupled to the tilting frame 21 to the scaffolding frame 41 to which the connecting member 61 is coupled. The longer the length from the part or the part of the scaffolding frame 41 to which the connecting member 61 is coupled to the scaffolding 42 is increased. Therefore, the width between the pair of connecting members 61 coupled to the support frame 31 is increased, or the scaffolding frame 41 coupled to the tilting frame 21 at the portion of the footrest frame 41 to which the connecting member 61 is coupled It is possible to increase the width between the pair of straight extension lines x by configuring the length from the portion of the footrest frame 41 coupled to the tilting frame 21 to the footrest 42 longer than the length to the portion.
본 발명의 실시예에서, 발판(42)이 결합된 축 또는 발판프레임(41) 일단 부위 중 발을 얹을 수 있게 양 측방으로 돌출된 부위에 위치한 한 쌍의 직선연장선(x) 사이 폭(w)은 최소 15cm이상 되게 구성된다.In an embodiment of the present invention, the width (w) between a pair of straight extension lines (x) located at a portion protruding in both sides so that the foot can be placed on one of the shaft or the footrest frame 41 to which the footrest 42 is coupled Consists of at least 15cm.
즉, 성인이 양발을 조금 벌린 상태로 탑승할 경우 탑승자 발이 직선연장선(x) 위 또는 한 쌍의 직선연장선(x) 사이에 위치할 수 있게 하기 위해 발이 얹히는 부위에 위치한 한 쌍의 직선연장선(x) 사이 폭(w)은 최소 15cm이상 되게 구성된다.In other words, when an adult boards with both feet slightly wide open, a pair of straight extension lines located in the area where the feet rest in order to allow the occupant's feet to be located above the straight extension line (x) or between a pair of straight extension lines (x) ( x) The width w is configured to be at least 15cm.
탑승자 체중이 안장(52)에 대부분 실리고 발판(42)에는 조금 실리지만, 틸팅본체(20)가 조금 기울어진 상태에서는 탑승자 체중이 누르는 힘의 방향과 틸팅본체(20)가 기울어지려고 하는 힘의 방향이 90도에 가깝기 때문에 발판(42)을 누르는 힘이 적어도 틸팅본체(20)가 세워지게 된다. 그리고 발판부(40) 타단이 지지프레임(31)에 걸리고 발판부(40) 중간 부분이 틸팅프레임(20)을 누르는 구조임으로 발판부(40)를 누르는 힘이 증폭되어 발판부(40)가 틸팅프레임(20)을 누르게 된다. 또한 기울어진 쪽에 위치한 발판(42)을 누르는 힘은 틸팅본체(20)가 기울어지는 쪽으로 작용 안하기 때문에 발판(42)에 발을 얹기만 해도 틸팅본체(20)는 측방으로 기울어지지 않게 된다. The weight of the occupant is mostly carried on the saddle 52 and a little on the footrest 42, but when the tilting body 20 is slightly inclined, the direction of the force pressed by the weight of the occupant and the direction of the force that the tilting body 20 tries to incline Since it is close to 90 degrees, the tilting body 20 is erected with at least the force pressing the foot plate 42. In addition, since the other end of the footrest 40 is caught by the support frame 31 and the middle of the footrest 40 presses the tilting frame 20, the force pressing the footrest 40 is amplified so that the footrest 40 is tilted. The frame 20 is pressed. In addition, since the force pressing the foot plate 42 located on the inclined side does not act toward the tilting body 20 inclined side, the tilting body 20 is not inclined laterally by simply placing the foot on the foot plate 42.
물론, 코너 주행시 안장에 실린 탑승자 체중을 코너 안쪽으로 이동시켜 틸팅본체(20)가 코너 안쪽으로 기울어지게 할 수 있다.Of course, when driving a corner, the weight of the occupant carried on the saddle may be moved to the inside of the corner so that the tilting body 20 may be inclined toward the inside of the corner.
한편. 도 4와 도 5를 참조하면 틸팅본체(20)가 측방으로 기울어질 때 지지본체(30)도 같이 기울어지게 구성될 수도 있다.Meanwhile. Referring to FIGS. 4 and 5, when the tilting body 20 is inclined laterally, the support body 30 may also be configured to be inclined.
더 구체적으로 설명하면, 틸팅프레임(21)은 핸들프레임(12) 중간과 하부에 외삽 결합되는 체1틸팅프레임(22)과 제1틸팅프레임(22) 상단 후부에서 후방으로 길게 연장되는 제2틸팅프레임(23) 및 제1틸팅프레임(22) 하단 후부에 상하로 연장되는 제3틸팅프레임(24)으로 구성된다. More specifically, the tilting frame 21 includes a body 1 tilting frame 22 that is extrapolated to the middle and bottom of the handle frame 12 and a second tilting frame that extends long from the rear of the top of the first tilting frame 22 to the rear. It is composed of a frame 23 and a third tilting frame 24 extending up and down in the lower rear portion of the first tilting frame 22.
상기 제1틸팅프레임(22)은 핸들프레임(12) 중간과 하부에 외삽 결합되어 핸들프레임(12)이 회전 가능하게 구성된다.The first tilting frame 22 is externally coupled to the middle and lower portions of the handle frame 12 so that the handle frame 12 is rotatable.
상기 제2틸팅프레임(23)은 앞단이 제1틸팅프레임(22) 상단 후부에 결합되고 뒷단은 후방으로 길게 연장되면서 후방으로 연장된 끝단에 제1륜(14)이 결합된다.The front end of the second tilting frame 23 is coupled to the upper and rear end of the first tilting frame 22 and the rear end is extended to the rear, and the first wheel 14 is coupled to the end extending rearward.
상기 제3틸팅프레임(24)은 제1틸팅프레임(22) 하단 후부에 상하로 연장되는 형태로 고정 결합되고, 상단 부위에서 후방으로 조금 연장되게 구성되며, 후방으로 연장된 부위에 발판프레임(41)이 결합될 수 있게 구성된다.The third tilting frame 24 is fixedly coupled to the lower rear portion of the first tilting frame 22 in a form extending vertically, and is configured to slightly extend rearward from the upper portion, and the footrest frame 41 at the portion extending rearward. ) Is configured to be combined.
다음으로 지지프레임은 제3틸팅프레임(24) 중간 부위에 중간이 결합되는 제1지지프레임(35)과 제3틸팅프레임(24) 하단에 중간이 결합되는 제2지지프레임(36) 및 제1지지프레임(35)과 제2지지프레임(36) 양 끝단을 서로 연결시키는 바퀴결합부(37)로 구성된다.Next, the support frame includes a first support frame 35 that is coupled to the middle of the third tilting frame 24, and a second support frame 36 and a first support that is coupled to the lower end of the third tilting frame 24. The support frame 35 and the second support frame 36 are composed of a wheel coupling part 37 connecting both ends to each other.
상기 제1지지프레임(35)은 중간 부위가 제3틸팅프레임(24) 중간에 결합되고, 양 측방으로 연장된 양 끝단은 상하로 회전 가능하게 구성된다.The first support frame 35 has a middle portion coupled to the middle of the third tilting frame 24, and both ends extending in both sides are configured to be rotatable vertically.
상기 제2지지프레임(36)은 중간 부위가 제1지지프레임(35)이 결합된 부위 수직 하방에 위치한 제3틸팅프레임(24) 하단에 결합되고, 양 측방으로 연장된 양 끝단은 상하로 회전 가능하게 구성된다.The second support frame 36 is coupled to the lower end of the third tilting frame 24 located vertically below the area where the first support frame 35 is coupled, and both ends extending in both sides rotate up and down. It is configured to be possible.
상기 바퀴결합부(37)는 제1지지프레임(35) 양 끝단 부위와 제2지지프레임(36) 양 끝단 부위에 연결되면서 틸팅본체(20)가 좌측 또는 우측으로 기울어질 때 틸팅본체(20)와 같은 각도로 기울어지게 구성된다. 그리고 틸팅본체(20)가 기울어질 때 제1지지프레임(35)과 제2지지프레임(36)은 틸팅본체(20)가 기울어지는 방향과 반대 방향으로 회전하면서 수평 상태로 유지되게 구성된다. The wheel coupling part 37 is connected to both ends of the first support frame 35 and both ends of the second support frame 36, and the tilting body 20 is tilted when the tilting body 20 is inclined to the left or right. It is configured to be inclined at the same angle. And when the tilting body 20 is inclined, the first support frame 35 and the second support frame 36 are configured to be maintained in a horizontal state while rotating in a direction opposite to the direction in which the tilting body 20 is tilted.
제2륜(32)은 양 바퀴결합부(37) 바깥쪽에 각각 결합되어 바퀴결합부(37)가 기울어질 때 제2륜(32)도 같이 기울어지게 구성된다.The second wheels 32 are respectively coupled to the outer side of the both wheel coupling portions 37 so that the second wheel 32 is also inclined when the wheel coupling portion 37 is inclined.
상기와 같이 지지본체(30)가 기울어지는 구조는 이미 제품화가 된 기술이고 많이 응용되는 기술이라 간단히 언급만 하고 상세한 설명은 생략한다. The structure in which the support body 30 is inclined as described above is a technology that has already been commercialized and is a technology that is widely applied, so only briefly mentioning it and a detailed description will be omitted.
다음으로 발판프레임(41)은 중간 부분이 제3틸팅프레임(24) 부위 중 후방으로 연장된 끝단 부위에 결합되고, 일단은 후방으로 연장되게 구성되며, 일단 양측에 발판(42)이 각각 결합된다. 그리고 타단은 전방으로 연장되게 구성되고, 전방으로 연장된 끝단에서 양 측방으로 연장되게 구성되며, 양 측방으로 연장된 끝단에 연결부재(61)가 결합될 수 있게 구성된다. Next, the footrest frame 41 has an intermediate portion coupled to an end portion extending rearward among the third tilting frame 24, one end is configured to extend rearward, and one end footrest 42 is coupled to both sides, respectively. . And the other end is configured to extend forward, is configured to extend in both sides from the end extending forward, and the connecting member 61 is configured to be coupled to the ends extending in both sides.
다음으로 연결부재(61)는 일단이 발판프레임(41) 타단 양측에 각각 결합되고, 타단은 발판프레임(41) 타단 하방에 위치하면서 후술하는 회전중심축(p) 좌우측에 위치한 제2지지프레임(36) 부위에 결합된다.Next, the connecting member 61 has one end coupled to both sides of the other end of the scaffolding frame 41, and the other end is located below the other end of the scaffolding frame 41, while a second support frame ( 36) is bound to the site.
물론, 연결부재(61) 타단이 제2지지프레임(36)이 아닌 회전중심축(p) 좌우측에 위치한 제1지지프레임(35) 부위에 결합될 수도 있다.Of course, the other end of the connection member 61 may be coupled to a portion of the first support frame 35 located on the left and right sides of the rotational center axis p instead of the second support frame 36.
제2지지프레임(36)이 제3틸팅프레임(24)에 결합된 부위인 제2지지프레임(36) 회전 중심 지점에 연결부재(61) 타단이 결합되면 발판(42)을 눌려도 틸팅본체(20)가 기울어짐을 억제시키는 힘은 작용하지 않게 된다. When the other end of the connecting member 61 is coupled to the rotational center point of the second support frame 36, which is a portion where the second support frame 36 is coupled to the third tilting frame 24, the tilting body ( 20) The force that suppresses the tilt does not work.
지지본체(30)가 기울어지는 구조에서 회전중심축(p)은 틸팅본체(20)가 기울어지는 중심축이 아닌 제2지지프레(36)이 제3틸팅프레임(24)에 결합된 부위인 제2지지프레임(36) 회전 중심 지점에서 제1륜(14)을 향해 수평으로 그은 직선으로 구성된다.In the structure in which the support body 30 is inclined, the rotational center axis p is a part where the second support frame 36 is coupled to the third tilting frame 24, not the central axis at which the tilting body 20 is tilted. 2 It is composed of a straight line drawn horizontally toward the first wheel 14 at the rotation center point of the support frame 36.
물론, 연결부재(61)가 재1지지프레임(35)에 결합될 경우 회전중심축(p)은 제1지지프레임(35)이 제3틸팅프레임(24)에 결합된 부위인 제1지지프레임(35) 회전 중심 지점에서 제1륜(14)을 향해 수평으로 그은 직선으로 구성된다.Of course, when the connecting member 61 is coupled to the first support frame 35, the rotational center axis p is the first support frame, which is a portion where the first support frame 35 is coupled to the third tilting frame 24. (35) It is composed of a straight line drawn horizontally toward the first wheel 14 at the rotation center point.
연결부재(61) 타단이 제2지지프레임(36)에 결합되는 위치가 회전중심축(p)과 가까워질수록 틸팅본체(20)가 좌측 또는 우측으로 기울어질 때 발판부(40) 일단 부위가 상방으로 회전되는 폭이 작아지면서 틸팅본체(20)는 잘 기울어지게 되고, 회전중심축(p)에서 멀어질수록 발판부(40) 일단 부위가 상방으로 회전되는 폭이 커지면서 틸팅본체(20)는 잘 안 기울어지게 된다.As the position where the other end of the connecting member 61 is coupled to the second support frame 36 is closer to the rotational center axis p, the one end of the footrest part 40 becomes inclined to the left or right. As the width of the upward rotation decreases, the tilting body 20 is well inclined, and the farther from the rotation center axis p, the greater the width at which one end of the scaffolding portion 40 rotates upward, and the tilting body 20 becomes It will not tilt well.
여기서, 제2지지프레임(36)이 좌우측으로 기울어지는 구조지만 발판프레임(42) 티단과 제2지지프레임(36)을 연결부재(61)로 연결하고 발판(42)을 누를 경우, 제2지지프레임(36) 한쪽은 상방으로 당기지는 형태가 되고, 반대쪽 부위는 제2륜(32)이 받치고 있어 하방으로 이동할 수 없음으로 제2지지프레임(36)은 측방으로 기울어지지 않게 된다. Here, although the second support frame 36 is inclined to the left and right, when connecting the tee end of the footrest frame 42 and the second support frame 36 with a connecting member 61 and pressing the footrest 42, the second support One side of the frame 36 is pulled upward, and the second support frame 36 is not inclined laterally because the second wheel 32 is supported on the other side and cannot move downward.
즉, 제1지지프레임(35)과 제2지지프레임(36)이 옆으로 작용하는 힘에는 잘 기울어지지만 좌우측 중 어느 한쪽이 상방으로 당기지는 힘에는 잘 안 기울어진다. In other words, the first support frame 35 and the second support frame 36 are inclined well against the forces acting laterally, but are not well inclined against the force pulling one of the left and right upwards.
따라서, 상기와 같이 지지본체가 기울어지는 구조에서도 발판프레임 타단을 지지프레임에 연결하거나 걸리게 구성하고, 발판에 발을 얹어 틸팅본체가 기울어짐을 억제시킬 수 있다.Accordingly, even in the structure in which the support body is inclined as described above, the other end of the scaffolding frame may be connected to or caught on the support frame, and the tilting body may be prevented from tilting by placing a foot on the scaffolding.
상기와 같이 발판프레임(41) 타단이 지지프레임(31)에 걸리게 구성함으로써, 탑승자가 안장(52)에 앉을 경우 안장(52)에 실린 탑승자 체중을 좌우측 중 어느 한쪽으로 많이 이동하지 않는 이상 탑승자 발 다리 무게에 의해 틸팅본체(20) 기울어짐이 억제되기 때문에 안정적으로 탑승할 수 있는 효과가 있다.As described above, by configuring the other end of the footrest frame 41 to be caught on the support frame 31, when the occupant sits on the saddle 52, the occupant's foot is not moved much to one of the left and right. Since tilting of the tilting body 20 is suppressed by the weight of the legs, there is an effect of stably boarding.
또한, 틸팅본체(20)가 틸팅시에 기울어진 쪽에 위치한 발판(42)을 누를 경우, 틸팅본체(20)가 기울어지지 않기 때문에 기울어진 쪽에 위치한 발을 디딤발로 하여 안정적으로 탑승할 수 있는 효과가 있다. In addition, when the tilting body 20 presses the footboard 42 located on the inclined side during tilting, the tilting body 20 is not inclined, so that the foot located on the tilted side as a stepping foot has the effect of stably boarding. have.

도 7을 참조하면, 제2실시예에서 구름부(64)는 앞뒤로 구멍이 뚫린 원기둥 형상으로 구성된다. 그리고 발판프레임(41) 타단 양쪽에 구비된 축에 끼움 결합되어 측방으로 회전 가능하게 구성된다. Referring to FIG. 7, in the second embodiment, the rolling part 64 is configured in a cylindrical shape with holes in front and rear. And it is fitted to the shaft provided on both sides of the other end of the scaffolding frame 41 is configured to be rotatable laterally.
본 발명의 실시예에서 구름부(64)는 앞뒤로 구멍이 뚫린 원기둥 형상으로 구성됨을 제시하지만 지지부(62)에 접촉된 상태로 굴러갈 수 있는 형상이면 어떤 형상이든 상관없다.In the embodiment of the present invention, it is suggested that the rolling part 64 is configured in a cylindrical shape with holes in front and back, but any shape may be used as long as it can roll in contact with the support part 62.
하나의 실시예로 오목한 형상의 반구가 발판부(40) 타단 상부에 고정 결합되고, 반구 안쪽에 구 형태인 구름부(64)가 구름 가능하게 결합된다. 그리고 구름부(64)가 지지부(62)에 접촉되어 구름 회전 가능하게 구성될 수도 있다.In one embodiment, a concave hemisphere is fixedly coupled to an upper portion of the other end of the scaffolding portion 40, and a spherical rolling portion 64 is rollably coupled inside the hemisphere. In addition, the rolling part 64 may be configured to be rollable by contacting the support part 62.
제2실시예에서 지지부(62)는 지지판(34) 부위 중 상방으로 연장된 부위 사이에 삽입시켜서 볼트로 고정 결합된다. 그리고 한 쌍의 구름부(64)가 지지부(62)와 지지프레임(31) 사이에 삽입되어 지지부(62) 하부 좌우측에 접촉되게 구성되고, 구름부(64)가 접촉되는 지지부(62) 부위는 회전중심축(p) 상방에 위치하게 구성된다. 구름부(64)가 접촉되는 지지부(62) 부위 중 제1륜(14) 쪽에 위치한 부위는 회전중심축(p) 상방에 위치한 지지부(62) 가운데 부위에서 좌우측으로 향할수록 회전중심축(p)까지 길이가 조금씩 길어지면서 휘어지게 구성된다. In the second embodiment, the support portion 62 is fixedly coupled with a bolt by inserting it between the portions extending upward among the portions of the support plate 34. And a pair of rolling parts 64 are inserted between the support part 62 and the support frame 31 to be in contact with the lower left and right sides of the support part 62, and the part of the support part 62 to which the rolling part 64 contacts It is configured to be located above the rotation center axis (p). Among the parts of the support part 62 where the rolling part 64 is in contact, the part located on the side of the first wheel 14 is the rotation center axis (p), as the part of the support part 62 located above the center of the support part 62 goes to the left and right. It is configured to bend as the length increases little by little.
구름부(64)가 접촉되는 지지부(62) 부위를 상기와 같이 구성함으로써, 틸팅본체(20)가 측방으로 기울어질수록 기울어진 반대쪽에 위치한 구름부(64)는 지지부(62)에 접촉되어 지지부(62) 가운데로 구름 이동함과 동시에 회전중심축(p) 방향으로 조금씩 이동하게 된다. 그리고 발판프레임(41) 타단 부위가 회전중심축(p) 방향으로 이동함에 따라 기울어진 쪽에 위치한 구름부(64)는 지지부(62)에서 떨어지게 되고 발판부(40) 일단은 회전중심축(p)으로부터 멀어지게 된다. By configuring the part of the support part 62 to which the rolling part 64 is in contact as described above, the rolling part 64 located on the opposite side of which the tilting body 20 is inclined toward the side is in contact with the support part 62 (62) As the cloud moves to the center, it moves little by little in the direction of the rotation center axis (p). And as the other end of the scaffolding frame 41 moves in the direction of the rotational center axis (p), the rolling part 64 located on the inclined side is separated from the support part 62, and one end of the scaffolding part 40 is the rotational center axis (p). Away from
계속해서, 틸팅본체(20)가 측방으로 기울어질 때 제2륜(32) 쪽에 위치한 구름부(64) 부위가 회전중심축(p) 쪽으로 이동하기 때문에 제1륜(14) 쪽에 위치한 구름부(64) 부위가 지지부(62)에 점 접촉된다. 따라서 구름부(64)와 지지부(62)가 점접촉 안 되게 하기위해 틸팅본체(20)가 측방으로 기울어질 때 제2륜(32) 쪽에 위치한 구름부(64) 부위가 지지부(62)로부터 멀어지는 간격만큼 제2륜(32) 쪽에 위치한 구름부(64)에 접촉되는 지지부(62) 부위는 구름부(64) 쪽을 향하여 연장되게 구성되어야 한다.Subsequently, when the tilting body 20 is inclined to the side, the rolling part 64 located on the second wheel 32 side moves toward the rotational center axis p, so the rolling part located on the first wheel 14 side ( 64) The part is in point contact with the support part 62. Therefore, in order to prevent point contact between the rolling part 64 and the support part 62, when the tilting body 20 is inclined laterally, the part of the rolling part 64 located on the side of the second wheel 32 is moved away from the support part 62. A portion of the support part 62 that contacts the rolling part 64 located on the side of the second wheel 32 by an interval should be configured to extend toward the rolling part 64.
즉, 틸팅본체(20)가 측방으로 안 기울어졌을 때 구름부(64)가 접촉되는 지지부(62) 부위 중 제1륜(14) 쪽에 위치한 부위와 제2륜(32) 쪽에 위치한 부위에서 회전중심축(p)까지 길이가 같게 구성되고, 지지부(62) 가운데로 향할수록 회전중심축(p)까지 길이가 제1륜(32) 쪽보다 제2륜(14) 쪽이 조금씩 더 짧아지게 구성된다. 따라서 지지부(62)는 양쪽에서 가운데로 향할수록 제2륜(32) 쪽에 위치한 부위가 제1륜(14) 쪽에 위치한 부위보다 조금씩 하방으로 내려간 기울어진 면으로 구성된다. That is, when the tilting body 20 is not inclined laterally, the center of rotation is located on the first wheel (14) and the second wheel (32) of the support part 62 that the rolling part 64 contacts with. The length to the shaft (p) is the same, and the length to the rotational center shaft (p) becomes slightly shorter in the second wheel (14) side than the first wheel (32) side toward the center of the support part (62). . Accordingly, the support part 62 is composed of an inclined surface in which a portion located on the second wheel 32 side gradually descends downward from a portion located on the first wheel 14 side toward the center from both sides.
틸팅본체(20)가 측방으로 최대로 기울어졌을 때 구름부(64)가 회전중심축(p) 수직 상방에 위치한 지지부(62) 부위를 넘어가면 구름부(64)가 접촉된 지지부(62) 부위에서 회전중심축(p)까지 길이가 길어지게 된다. 따라서 틸팅본체(20)가 최대로 기울어진 상태에서 구름부(64)는 회전중심축(p) 수직 상방에 위치한 지지부(62) 부위를 넘어가지 않게 구성되어야 한다.When the tilting body 20 is inclined to the maximum side and the rolling part 64 crosses the supporting part 62 located vertically above the rotation center axis p, the supporting part 62 where the rolling part 64 contacts The length from to the center of rotation (p) becomes longer. Therefore, in the state where the tilting body 20 is inclined to the maximum, the rolling part 64 should be configured not to cross the support part 62 located vertically above the rotation center axis p.
제2실시예서 직선연장선(x)은 틸팅본체(20)가 측방으로 기울어지지 않은 상태를 평면도로 그렸을 때 앞뒤는 발판프레임(41)이 틸팅프레임(21)에 결합된 부위와 일치하고, 좌우는 회전중심축(p)에 일치하는 지점과 구름부(64)가 지지부(62)에 접촉된 부위 중앙 지점을 직선으로 그은 직선이 발판(42)까지 연장된 가상의 직선으로 구성된다.In the second embodiment, when the tilting body 20 is drawn in a plan view in which the tilting body 20 is not inclined to the side, the front and rear sides coincide with the part where the scaffolding frame 41 is coupled to the tilting frame 21, and the left and right A straight line drawn in a straight line between a point coincident with the rotational center axis p and a central point of a portion in which the rolling portion 64 contacts the support portion 62 is formed as a virtual straight line extending to the scaffold 42.
제1실시예와 같이 틸팅본체(20)가 측방으로 기울어지면 직선연장선(x)을 기준으로 좌측 또는 우측 중 어느 한쪽에 위치한 발판(42)을 틸팅본체(20)가 기울어진 각도와 같은 방향으로 누르면 누른 방향 쪽으로 발판부(40)와 틸팅본체(20)가 기울어지게 된다. When the tilting body 20 is inclined laterally as in the first embodiment, the footrest 42 located on either the left or the right side with respect to the straight extension line x is moved in the same direction as the tilting body 20 inclined angle. When pressed, the footrest portion 40 and the tilting body 20 are inclined toward the pressed direction.
틸팅본체(20)가 좌측 또는 우측으로 기울어질 경우 제1실시예와 같이 상방으로 이동된 발판(42)을 누르는 지점은 직선연장선(x)으로부터 일정 간격 측방에 위치하기 때문에 상방으로 이동된 발판(42)을 누르는 힘은 틸팅본체(20)가 세워지는 쪽으로 작용하게 되어 제1실시예와 같은 효과를 얻을 수 있다. When the tilting body 20 is inclined to the left or right, as in the first embodiment, the point where the foot plate 42 is pressed is located at a certain distance from the straight extension line x, so the foot plate moved upward ( The force pressing 42) acts on the side where the tilting body 20 is erected, so that the same effect as in the first embodiment can be obtained.

An imaginary straight line extending to the scaffold 42 is a straight line drawn from the point coincident with the part, and the center point of the part where the rolling part 64 contacts the support part 62 and the point coincident with the rotation center axis (p) on the left and right Consists of
도 9에서 e를 참조하면, 발판부(40) 부위 중 4부위를 누르면 발판부(40)가 3위치에 있는 틸팅프레임(21) 부위를 상방으로 밀게 되고, 5부위를 누르면 2위치에 있는 틸팅프레임(21) 부위를 상방으로 밀게 되고, 6부위를 누르면 1위치에 있는 틸팅프레임(21) 부위를 상방으로 밀게 된다. 따라서 5부위을 누르면 틸팅본체(20)가 어느 쪽으로도 기울어지지 않게 되고, 4부위와 6부위를 누르면 누른 방향 쪽으로 틸팅본체(20)가 기울어지게 됨으로 2부위와 5부위를 그은 직선이 직선연장선(x)이 된다. Referring to e in FIG. 9, when pressing 4 of the scaffolding part 40, the scaffolding 40 pushes the tilting frame 21 at the 3 position upward, and pressing the 5 thrust tilting at the 2nd position The frame 21 part is pushed upward, and when part 6 is pressed, the part of the tilting frame 21 in the 1 position is pushed upward. Therefore, if you press the 5 part, the tilting body 20 will not be inclined in any direction, and if you press the 4 part and 6 part, the tilting body 20 inclines in the direction in which it was pressed, so that the straight line drawing the 2nd and 5th parts is a straight extension line (x ).
구름부재(66)와 마주보는 지지부(62) 하부에 탄성부재(63)가 결합될 수 있다. The elastic member 63 may be coupled to the lower portion of the support 62 facing the rolling member 66.
상기 탄성부재(63)는 구름부재(66)가 접촉되는 부위로 구름부재(66)가 접촉 시, 구름부재(66)와 지지부(62)가 서로 점 접촉되지 않게 하고, 틸팅본체(20)가 좌측 또는 우측으로 기울어진 후 기울어진 반대쪽에 위치한 지지부(62) 부위가 구름부재(66)에 접촉될 때 발생하는 충격을 흡수할 수 있게 구성된다. The elastic member 63 is a portion where the rolling member 66 is in contact, and when the rolling member 66 is in contact, the rolling member 66 and the support part 62 do not point to each other, and the tilting body 20 After being inclined to the left or right, the support part 62 located on the opposite side of the inclined portion is configured to absorb the shock that occurs when it comes into contact with the rolling member 66.
본 발명의 실시예에서 탄성부재(63)는 기계적 성질이 우수한 우레탄고무로 구성됨을 제시한다.In the embodiment of the present invention, it is suggested that the elastic member 63 is made of urethane rubber having excellent mechanical properties.
지지부(62)에 접촉되는 구름부재(66)가 구 형상이라 우레탄고무 경도가 너무 높으면, 우레탄고무와 구름부재(66)가 서로 접촉되는 면적이 작게 형성되어 접촉 부위에 너무 높은 압축응력이 발생하고, 우레탄고무 경도가 너무 낮으면, 접촉 면적이 증가하여 단위 면적당 압축응력은 작게 발생하지만, 구름부재(66)가 우레탄고무에 너무 깊게 압입되는 문제가 발생할 수 있다. 따라서 본 발명의 실시예에서 우레탄고무는 쇼어 경도 a60에서 a95정도 되는 우레탄고무로 구성됨을 제시하지만, 지지부(62)에 접촉되는 구름부재(66) 크기에 따라 접촉부위에 발생하는 압축응력이나 압입깊이가 달라지므로 한정하는 것은 아니다.If the urethane rubber hardness is too high because the rolling member 66 in contact with the support part 62 is spherical, the area in which the urethane rubber and the rolling member 66 contact each other is formed so that too high compressive stress occurs in the contact area. If the hardness of the urethane rubber is too low, the contact area increases and the compressive stress per unit area is small, but the rolling member 66 may be pressed too deeply into the urethane rubber. Therefore, in the embodiment of the present invention, it is suggested that the urethane rubber is composed of urethane rubber having a shore hardness of a60 to a95, but the compressive stress or the indentation depth generated at the contact portion depending on the size of the rolling member 66 in contact with the support part 62 Is not limited because it changes.
한편, 구름부(64)는 제2실시예 같이 원기둥 형상으로 구성되고, 구름부(64)에 접촉되는 지지부(62) 부위는 가운데가 들어간 형상이 아닌 상방으로 튀어나온 형상으로 구성될 수도 있다. On the other hand, the cloud portion 64 is configured in a cylindrical shape as in the second embodiment, and the portion of the support portion 62 in contact with the cloud portion 64 may be formed in a shape that protrudes upward rather than a centered shape.
즉, 도 10에서 a 내지 d와 같이, 지지부(62)는 틸팅프레임(21)에 결합된 발판부(40) 부위로부터 제1륜(14) 쪽에 위치한 지지프레임(51) 상부에 고정 결합되고, 구름부(64)는 지지부(62)와 마주보는 발판프레임(41) 부위에 결합되어 지지부(62) 상부에 접촉되게 구성될 수도 있다. 그리고 구름부(64)가 접촉되는 지지부(62) 부위는 회전중심축(p) 상방에 위치하게 구성된다.That is, as shown in FIG. 10 a to d, the support portion 62 is fixedly coupled to the upper portion of the support frame 51 located on the first wheel 14 side from the portion of the footrest portion 40 coupled to the tilting frame 21, The cloud portion 64 may be coupled to a portion of the scaffolding frame 41 facing the support portion 62 and may be configured to be in contact with the upper portion of the support portion 62.
