Description

충격 흡수용 안전 난간{A safety fence for shock absorbing}A safety fence for shock absorbing

본 발명은 충격 흡수용 안전 난간에 관한 것으로, 특히 자전거 전용 도로 또는 도보용 거리 등에 설치된 난간의 구조를 개선하여 자전거를 타고 가다가 넘어져 난간에 충돌하거나 또는 도보를 걷다가 부주의로 난간에 부딪히는 경우에 충격을 흡수하여 난간으로부터 사람을 보호해 줄 수 있도록 한 것이다.The present invention relates to a shock absorbing safety railing, and in particular, by improving the structure of the railings installed on bicycle paths or walking streets, the impact of a bump on the railing or inadvertently hitting the railing while walking on the bicycle. It will be absorbed to protect people from railings.

최근, 건강에 관한 관심 증대와 에너지 절약 등의 일환으로 조깅과 걷기, 자전거 타기 등이 활발히 증가하고 있는 추세이며 보도 또는 자전거 전용도로에 관한 요구가 커지고 있는 실정으로, 보도, 자전거 전용 도로의 건설이 증가하고 있다.In recent years, jogging, walking and cycling have been actively increasing as a result of increased interest in health and energy saving, and the demand for sidewalks and bicycle paths is increasing. It is increasing.

종래에는 자전거 전용도로의 난간 설치대에 있어서, 일반적으로 지주를 자전거 전용도로의 측부에 배열설치하게 되고, 상기 지주 사이로 와이어 및 봉을 연결하여 설치가 되도록 함으로써 자전거를 타고 주행시 운전 부주의로 지주와 충돌할 경우 탑승자에 심각한 부상이 발생하게 되는 문제점이 있다.Conventionally, in the railing mount of a bicycle-only road, struts are generally arranged on the side of the bicycle-only road, and wires and rods are connected to each other so that the pillars may be inadvertently collided with the support when driving on a bicycle. If there is a problem that serious injury occurs in the occupant.

또한, 와이어로프 및 봉에 텐션이 제공되지 않아 와이어로프와 봉에 충돌시에도 적잖은 부상의 우려가 발생할 수 있다.In addition, since tension is not provided to the wire rope and rods, a slight injury may occur even when the wire rope and the rod collide with each other.

일반적인 안전 난간은 철재 또는 목재로 구성되어 도로나 다리 등에서 일정구역을 지지해주도록 설치함으로써 자전거 등을 타다가 충돌하여도 옆으로 떨어지거나 외측으로 이탈하여 부상을 당하지 않도록 하는 수단으로 사용되고 있다. The general safety railing is made of steel or wood and installed to support a certain area on a road or a bridge, so that it is used as a means to prevent injuries by dropping to the side or leaving the outside even when a bicycle is collided.

그러나 상기와 같은 종래의 안전 난간은 자전거나 보행시 다리나 길에서 옆으로 이탈하거나 또는 떨어지지 않도록 안전 난간으로서의 역할은 하지만, 이러한 난간이 철재나 목재 등으로 이루어져 있어 난간에 사람이 충돌시 충격을 전혀 흡수하지 못하고 그대로 충격이 전달되므로 충격 강도가 높아 부상을 당하거나 넘어져 상처를 입기 쉬운 문제가 있다.However, the above-described conventional safety railings serve as safety railings so as not to deviate or fall sideways from a bridge or a road when cycling or walking. However, since these railings are made of steel or wood, the railing absorbs no impact when a person collides. Since the shock is transmitted as it is not possible, the impact strength is high, so there is a problem of being easily injured or falling and being injured.

또한, 종래에는 난간에 스프링을 설치하여 난간 충격시 스프링의 완충작용에 의해 충격을 완화하도록 하는 기술이 제안되었으나, 이 경우 스프링이 난간 상측 또는 하측에만 설치되고 외측으로 돌출되게 설치되어 있어 충격흡수효과가 적음과 함께 스프링의 외부 돌출 설치로 녹이 슬거나 장시간 사용시 제구실을 하지 못하게 되는 등의 결점이 있었다.In addition, in the related art, a technique for mitigating impact by buffering action of the spring during the impact of the guardrail by installing a spring on the railing has been proposed. In addition, there was a drawback such as rusting due to the external protruding installation of the spring and the inability to operate the control room for a long time.
