Description

안전사다리{a safety ladder}Safety Ladder {a safety ladder}

본 고안은 주로 선박 및 대형탱크에 경사지거나 수직으로 설치하는 금속재 안전사다리에 관한 것이다.The present invention mainly relates to a metal safety ladder installed inclined or vertically in ships and large tanks.

종래의 선박 및 대형탱크에 경사지거나 수직으로 설치하는 금속재 사다리는 파이프지주(1)에 미끄럼방지돌환(201)을 형성한 반원계단(2)을 용접하여서 된 것으로서 발이 미끄러지는 것을 방지할수 있었으나 사다리를 오르고 내릴 때 반원계단(2)에 손을 잡게 되는데 이때 표면에 거친 금속제의 미끄럼방지돌환(201)에 의해 손이 손상되어 오히려 안전사고가 자주 발생하게 되는 문제가 따르게 되었다.The metal ladder installed inclined or vertically installed in a conventional ship and a large tank was made by welding a semicircular staircase (2) having a non-slip protrusion (201) formed on a pipe column (1). As you go up and down, you take your hand on the semi-circular staircase (2). At this time, the hands are damaged by the non-slip metal projections 201 of rough metal on the surface, so that safety accidents often occur.

본 고안은 상기와 같은 문제점을 해결하기 위하여 반원계단(2)양측에 안전손잡이(3)가 삽입되어 사다리를 구성함으로써, 미끄럼방지돌환(201)에 의해 손이 손상되는 안전사고를 방지할 수 있도록 하고, 또한 안전손잡이(3)는 외부에 톱니모양의 미끄럼방지요철(301)을 형성하여 손이 미끄러지는 것을 방지하고, 내부에 회전방지턱(302)이 형성되어 반원계단(2)에 삽입된 안전손잡이(3)가 헛돌지 않도록한 안전사다리를 제공하는데 그 목적이 있다.The present invention is to solve the above problems by constructing a ladder by inserting the safety handle (3) on both sides of the semi-circular staircase (2), so as to prevent the safety accident that the hand is damaged by the non-slip projection 201 In addition, the safety handle (3) has a serrated non-slip unevenness 301 on the outside to prevent the hand from slipping, the anti-rotation jaw 302 is formed inside the safety inserted into the semi-circular stairs (2) It is an object of the present invention to provide a safety ladder that prevents the handle 3 from turning.

이하 첨부된 도면을 참조하여 본 고안의 안전사다리에 대해 상세히 설명한다.Hereinafter, a safety ladder of the present invention will be described in detail with reference to the accompanying drawings.

도2내지 도3에 도시 된 바와같이 본 고안은 미끄럼방지 반원계단(2)의 양측에 톱니모양의 미끄럼방지돌기(301)와 회전방지턱(302)을 형성한 안전손잡이(3)가 삽입된 것이다.As shown in Figures 2 to 3, the subject innovation is that the safety handle (3) having the serrated non-slip projections (301) and the anti-rotation jaw (302) is inserted on both sides of the anti-slip semi-circular step (2). .

또한, 상기 안전손잡이(3)는 탄성을 가지는 고무 또는 플라스틱재질을 이용한다.In addition, the safety handle (3) uses a rubber or plastic material having elasticity.

한편, 양측에 안전손잡이(3)가 삽입된 미끄럼 방지 반원계단(2)은 일정간격으로 한쌍의 파이프지주(1)에 용접이 되어 안전사다리의 기능을 갖는다.On the other hand, the anti-slip semicircular staircase (2) in which the safety handle (3) is inserted on both sides is welded to a pair of pipe column (1) at regular intervals to have the function of a safety ladder.

이와같이 본 고안은 도1과 같이 미끄럼방지돌환(201)을 형성하여 발이 미끄러지는 것을 방지하게 하는 반원계단(2)은 종래와 동일한 바,As such, the present invention forms a non-slip protrusion 201 as shown in FIG.

상기의 작동에 있어서 반원계단(2)의 양측에 삽입되는 안전손잡이(3)는 계단을 오르고 내릴 때 표면이 거친 금속재의 미끄럼방지돌환(201)에 손이 상하게 되는 것을 방지할 수 있다.In the above operation, the safety knob 3 inserted into both sides of the semicircular step 2 can prevent the hand from being damaged by the non-slip protrusion 201 of the rough metal when the stairs are up and down.

또한, 도3에 도시된 바와 같이 안전손잡이(3)는 외부에 톱니모양의 미끄럼방지돌기(301)와 내부에 회전방지턱(302)로 형성되어 있는바,In addition, as shown in Figure 3, the safety handle (3) is formed with a serrated non-slip projection 301 on the outside and a rotation preventing jaw 302 therein,

길이방향으로 형성된 다수의 톱니모양의 미끄럼방지돌기(301)는 안전손잡이(3)를 잡고 계단을 오르거나 내려올 때 손이 미끄러지는 것을 방지하게 되며, 안전손잡이(3)의 내부에 형성된 회전방지턱(302)은 반원계단(2)의 안쪽에 끼워짐으로써 반원계단(2)에 삽입된 안전손잡이(3)가 헛도는 것을 방지하게 된다.A plurality of serrated non-slip projections 301 formed in the longitudinal direction to prevent the hand from slipping when climbing or descending the stairs holding the safety handle (3), the anti-rotation jaw formed in the safety handle (3) 302 is fitted inside the semi-circular step 2 to prevent the safety knob 3 inserted in the semi-circular step 2 from being lost.

이와같이 본 고안은 미끄럼방지돌환(201)을 형성하고 있는 반원계단(2)의 양측에 고무나 플라스틱재의 안전손잡이(3)를 삽입, 장착시킴으로써 반원계단(2)의 미끄럼방지돌환(201)에 손을 상하지 않고 신속 용이하게 사다리를 오르거나 내려 올 수 있음과 아울러 미끄러짐으로 인한 안전사고를 방지할 수 있다.In this way, the present invention inserts and mounts the safety knob 3 of rubber or plastic material on both sides of the semi-circular step 2 forming the anti-slip projection 201, thereby preventing the anti-slip ring 201 of the semi-circular step 2. The ladder can be climbed up or down quickly without damage, and safety accidents caused by slipping can be prevented.
