도 1 내지 도 3은 본 발명에 의한 실시예를 나타낸 것이다. 1 to 3 show an embodiment according to the present invention.
도 4 내지 도 6은 본 발명에 의한 요부를 구체적으로 도시한 것이다. 4 to 6 specifically show the main part according to the present invention.
도 7은 본 발명에 의한 사용상태를 나타낸 것이다. Figure 7 shows the use state according to the present invention.
이하, 첨부된 도면을 참조하여 본 발명에 의한 실시예의 구성 및 작용을 구체적으로 설명한다. Hereinafter, with reference to the accompanying drawings will be described in detail the configuration and operation of the embodiment according to the present invention.
도 1 내지 도 3을 참조하면, 본 발명에 의한 충격흡수용 가드레일(1)은 매립 지주(1)와, 레일부(20)와, 회전롤러(3)를 포함한다. 1 to 3, the shock absorbing guard rail 1 according to the present invention includes a buried strut 1, a rail portion 20, and a rotating roller 3.
상기 매립 지주(1)는 소정 간격으로 지중에 설치되는 구성요소이다. 또한 상기 매립지주(1)의 상면에는 지주캡(13)이 결합되어 있다. The buried prop 1 is a component installed in the ground at predetermined intervals. In addition, the holding cap 13 is coupled to the upper surface of the landfill (1).
상기 레일부(2)는 상기 매립 지주(1)에 횡방향으로 결합되는데, 특히 본 실시예에서는 상부레일(21)과 하부레일(22)이 나란하게 결합되어 있음을 알 수 있다. 상기 상부레일(21)과 하부레일(22)은 상기 매립 지주(1)에 각각 나사(11,12)로 체결된다. The rail portion 2 is coupled to the buried strut 1 in the lateral direction, and in this embodiment, it can be seen that the upper rail 21 and the lower rail 22 are coupled side by side. The upper rail 21 and the lower rail 22 are fastened to the buried strut 1 with screws 11 and 12, respectively.
상기 회전롤러(3)는 상기 매립 지주(1)에 관통되어 회전 가능하게 설치되는 구성요소로서, 차량 충돌시 충격을 흡수하고, 충돌된 차량을 다시 정상 진행방향으로 복귀시키기 위한 것이다. 상기 회전롤러(3)에는 야간에 시선을 유도하는 반사지(S)가 부착되어 있다. 상기 회전롤러(30)는 상기 지주에 한 쌍의 상하로 적층되어 설치되며, 이에 대해서는 구체적으로 후술하기로 한다. The rotary roller 3 is a component that is rotatably installed to penetrate the buried support (1), to absorb the shock during the vehicle crash, and to return the crashed vehicle to the normal running direction again. The rotating roller (3) is attached with a reflecting paper (S) for inducing a gaze at night. The rotary roller 30 is installed to be stacked in a pair of up and down on the support, which will be described later in detail.
도 4를 참조하면, 상기 매립 지주(10)들 사이에는 보조지주(40)가 복수개 구비되어 있다. 상기 보조지주(40)는 매립 지주(10)들 사이에도 회전롤러(30)를 회전 가능하도록 구비하기 위한 것이다. Referring to FIG. 4, a plurality of auxiliary pillars 40 are provided between the buried pillars 10. The auxiliary column 40 is to provide a rotatable roller 30 between the buried pillars (10).
즉, 상기 보조지주(40)는 상부와 하부에 체결홀(41,43)이 형성되어 있고, 상기 체결홀(41,43)에 볼트(42,44)가 관통하여 상기 상부레일(21)과 하부레일(22)에 나사결합되고, 상기 보조지주(40)에도 상기 한 쌍의 회전롤러(30A,30B)가 적층되어 관통되어 설치된다. 또한 상기 보조지주(40)의 상부에도 지주캡(13)이 씌워져 있다. That is, the auxiliary column 40 has fastening holes 41 and 43 formed at upper and lower portions thereof, and bolts 42 and 44 penetrate through the fastening holes 41 and 43 and the upper rail 21. Screwed to the lower rail 22, the pair of rotary rollers (30A, 30B) is also laminated to the auxiliary column 40 is installed through. In addition, the support cap 13 is also covered with an upper portion of the auxiliary column 40.
도 5를 참조하면, 본 실시예(1)에 의한 회전롤러(30)는 외피(31)를 PE 재질로 내부가 중공되도록 형성한 후((a) 참조), 상기 외피(31)의 내부에서 우레탄을 발포하여 충격흡수재(32)를 형성함으로써 완성체를 제조한다((b) 참조). 상기 외피(31)의 외주면에는 반사지를 부착할 수 있는 홈(33)이 형성된다.Referring to Figure 5, the rotary roller 30 according to the present embodiment (1) after forming the outer shell 31 to be hollow inside the PE material (see (a)), the inside of the outer shell 31 Urethane is foamed to form the shock absorbing material 32 to produce a finished product (see (b)). The outer circumferential surface of the outer shell 31 is formed with a groove 33 for attaching the reflective paper.
즉, 본 발명에 의하면 회전롤러(30)는 외피(31)와 충격흡수재(32) 등 2개 부분이 이종의 재질로 형성되는데, 이로써 상대적으로 경도가 높은 외피(31)로 인해 차량 충돌시 파손을 방지하고, 또한 충격흡수재(32)가 충돌시 발생되는 충격을 흡수하여 운전자 및 차량을 보호하는 것이다. That is, according to the present invention, the rotary roller 30 has two parts, such as the outer shell 31 and the shock absorbing material 32, formed of a heterogeneous material, thereby causing damage during vehicle collision due to the relatively high outer shell 31. And also, the shock absorber 32 is to protect the driver and the vehicle to absorb the shock generated when the collision.
특히, 본 실시예(1)는 상기 충격흡수재(32)로서 우레탄을 발포 성형한 다음, 외피(31)의 내부에 삽입하는 것이 아니라 외피(31)의 내부에서 우레탄을 발포 성형함으로써 일체화하여 형성한다는 특징이 있다. 이와 같이 외피(31)의 내부에서 우레탄을 발포 성형하게 되면 회전롤러의 강도가 향상될 뿐만 아니라 제조가 용이하다. In particular, the present embodiment (1) is formed by integrally forming the urethane as the impact absorbing material (32), and then by urethane foaming the inside of the outer shell (31) instead of inserting the inside of the outer shell (31) There is a characteristic. In this way, if the urethane foamed in the interior of the shell 31, the strength of the rotary roller is improved as well as easy to manufacture.
또한 본 발명에 의하면 회전롤러(30A,30B)는 2개를 상하로 적층하여 매립 지주(10)또는 보조지주(40)에 관통되도록 설치한다. In addition, according to the present invention, the rotary rollers 30A and 30B are installed so as to penetrate the buried support 10 or the auxiliary support 40 by stacking two up and down.
그런데, 상기 회전롤러(30A,30B)는 상하로 적층된 상태에서 상호 접하는 면으로부터 상부 또는 하부로 갈수록 반경이 커지도록 형성된다는 것을 알 수 있다(r2<r1=r3). By the way, it can be seen that the rotary rollers (30A, 30B) are formed such that the radius is larger toward the top or bottom from the surface in contact with each other in the stacked state up and down (r2 <r1 = r3).
즉, 회전롤러(30A,30B)는 측벽 전체 또는 일부에서 종단면에 경사면(34)이 형성되어 반경이 축소되는 구간이 형성된다. That is, the rotating rollers (30A, 30B) are formed in the section in which the inclined surface 34 is formed in the longitudinal section on the whole or part of the side wall to reduce the radius.
그리고 한 쌍의 회전롤러(30A,30B)를 상하로 적층할 때, 반경이 축소된 구간이 서로 맞닿도록 적층하여 매립 지주(10) 또는 보조지주(40)에 설치하는 것이다. 따라서 설치된 상태에서 한 쌍의 회전롤러(30A,30B)는 마치 장구형태를 갖게 된다. 이와 같이 중심부분의 반경(r2)이 가장 좁고, 상부 및 하부로 갈수록 반경(r1,r3)이 커지도록 형성함으로써 충돌한 차량이 승월하는 것을 효과적으로 방지할 수 있다. When the pair of rotary rollers 30A and 30B are stacked up and down, the sections with reduced radii are stacked so as to be in contact with each other and are installed in the buried prop 10 or the auxiliary support 40. Therefore, the pair of rotary rollers (30A, 30B) in the installed state has a gusset shape. In this manner, the radius r2 of the central portion is the narrowest, and the radius r1 and r3 are increased toward the upper portion and the lower portion, thereby effectively preventing the crashed vehicle from climbing.
도 6을 참조하면, 본 발명에 의한 충격흡수용 가드레일은 한 쌍의 회전롤러(30A,30B)는 상부레일(21)과 하부레일(22) 사이에 구비된다. 그런데 상기 상부레일(21)과 하부레일(22) 사이의 간격(공간, t3)이 한 쌍의 회전롤러(30A,30B)의 높이의 합(t1)보다 더 크게 설치된 것을 알 수 있다(t3>t1). 즉, 한 쌍의 회전롤러(30A,30B)가 적층되어 설치된 상태에서 상기 회전롤러(30A,30B)의 상면과 상부레일(21) 사이에도 소정의 공간(t2)가 존재한다. Referring to Figure 6, the shock absorbing guardrail according to the present invention is a pair of rotary rollers (30A, 30B) is provided between the upper rail 21 and the lower rail (22). By the way, it can be seen that the spacing (space, t3) between the upper rail 21 and the lower rail 22 is greater than the sum t1 of the heights of the pair of rotary rollers 30A and 30B (t3>). t1). That is, a predetermined space t2 exists between the upper surface of the rotary rollers 30A and 30B and the upper rail 21 in a state where a pair of rotary rollers 30A and 30B are stacked and installed.
도 7을 참조하면, 차량이 충돌할 경우, 상부에 적층된 회전롤러(30A)가 상방으로 힘을 외력을 받아 상부레일(21)에 맞닿을 때까지 상승하게 된다. 이 때 한 쌍의 회전롤러(30A,30B) 사이에는 소정의 갭(G)이 형성되고, 이러한 동작으로 차량 충돌에 의한 충격을 일부 흡수할 수 있고, 또한 이와 같은 동작으로 상부에 적층된 회전롤러(30A)가 상승하게 되어 결과적으로 방호책의 높이가 높아지게 되므로 차량 충돌시 차량이 승월하는 것을 방지하게 된다. Referring to FIG. 7, when the vehicle collides with each other, the rotating roller 30A stacked on the upper portion is raised until it comes in contact with the upper rail 21 by receiving an external force. At this time, a predetermined gap G is formed between the pair of rotary rollers 30A and 30B, and by this operation, a part of the impact caused by the collision of the vehicle can be absorbed, and the rotary rollers stacked on the upper part by such an operation. The 30A rises and, as a result, the height of the protective measure is increased, thereby preventing the vehicle from climbing.
본 발명은 차량 충돌시 승월을 방지하고 충격을 완화할 수 있어 산업상 이용가능성이 있다. Industrial Applicability The present invention has industrial applicability as it can prevent the rise of a vehicle crash and mitigate impact.
