외관은 종래 사용되는 사다리(2)와 같이 양측면에 수직으로 프레임이 형성되고, 그 사이에 수평으로 연장되는 바아가 다수 연결되어 있다. 그러나 본 발명에 의한 조립식 사다리는 다수의 분리되는 조립부재(12)로 구성되며 조립부재(12)의 구조가 도 3을 참고하여 후에 설명된다.Appearance is a frame is formed vertically on both sides, like a ladder (2) conventionally used, a number of bars extending horizontally between them is connected. However, the prefabricated ladder according to the present invention is composed of a plurality of separate assembly members 12 and the structure of the assembly member 12 will be described later with reference to FIG.

또한 조립식 사다리 본체(10)의 상단부에는 지지봉(16)이 연결되고, 하단부 에는 흡입판(14)이 연결된다. 상기 흡입판(14)은 본 발명의 조립식 사다리가 바닥면과 접촉되어 사용될 때에 지지력을 높이기 위한 것이다. 이에 비하여 지지봉(16)은 통상 벽면과 접촉되어져 사용된다. 상기와 같은 흡입판(14)은 특히 바닥면이 매끄러운 경우에 매우 유용하다.In addition, the support rod 16 is connected to the upper end of the prefabricated ladder body 10, and the suction plate 14 is connected to the lower end. The suction plate 14 is for increasing the supporting force when the prefabricated ladder of the present invention is used in contact with the bottom surface. In contrast, the support rod 16 is usually used in contact with the wall surface. Such a suction plate 14 is particularly useful when the bottom surface is smooth.

조립식 사다리 본체(10)를 구성하는 조립부재(12)는, 도 3을 참고하면, 사다리의 일측에 위치하는 제1결합부(121)와, 상기 제1결합부(121)의 상부에 결합되는 제1파이프(122)와, 상기 제1결합부(121)의 하부에 결합되는 제2파이프(126)와, 타측에 위치하는 제2결합부(124)와, 상기 제2결합부(124)의 상부에 결합되는 제3파이프(125)와, 상기 제2결합부(124)의 하부에 결합되는 제4파이프(128)를 포함하고 있다. 상기 제1결합부(121), 제2결합부(124), 제1파이프(122), 제2파이프(126), 제3파이프(125), 및 제4파이프(128)는 종래 사다리의 프레임을 구성하는 것이다.3, the assembly member 12 constituting the prefabricated ladder body 10, the first coupling portion 121 is located on one side of the ladder and is coupled to the upper portion of the first coupling portion 121 The first pipe 122, the second pipe 126 coupled to the lower portion of the first coupling portion 121, the second coupling portion 124 located on the other side, and the second coupling portion 124 The third pipe 125 is coupled to the upper portion of the, and the fourth pipe 128 is coupled to the lower portion of the second coupling portion 124. The first coupling part 121, the second coupling part 124, the first pipe 122, the second pipe 126, the third pipe 125, and the fourth pipe 128 are frames of a conventional ladder. To construct.

본 발명에 의하면, 상기 제1 및 제2결합부(121,124)는 종래 사용되는 T자형결합부(T-bow)와 본질적으로 동일한 형태를 갖는다. 도 3을 다시 참고하면, 제1 및 제2결합부(121,124)는 한 쌍의 수직 방향 및 단일의 수평방향으로 연장된 결합구멍을 갖는다. 제1 및 제2결합부(121,124)의 수직방향으로는 제1파이프(122) 및 제2파이프(126), 제3파이프(125) 및 제4파이프(128)가 각각 연결된다.According to the present invention, the first and second coupling parts 121 and 124 have the same shape as that of the T-bow. Referring again to FIG. 3, the first and second coupling parts 121 and 124 have a pair of coupling holes extending in a vertical direction and a single horizontal direction. The first pipe 122, the second pipe 126, the third pipe 125, and the fourth pipe 128 are respectively connected in the vertical direction of the first and second coupling parts 121 and 124.

특히 본 발명에서는 조립부재(12)의 상하결합을 위하여 일측, 즉 도면에서 상부측에 위치하는 제1 및 제3파이프(122,125)의 단부에는 테이퍼진 형태의 제1결합봉(122a) 및 제3결합봉(125a)가 각각 결합된다. 상기 제1결합봉(122a) 및 제3결합봉(125a)은 이동이 불가능하게 고정되며, 각각 중공이 형성되어 있다.In particular, in the present invention, the first coupling rod 122a and the third tapered shape are formed at the ends of the first and third pipes 122 and 125 positioned on one side, that is, the upper side in the drawing, for vertical coupling of the assembly member 12. Coupling rods 125a are coupled to each other. The first coupling rod 122a and the third coupling rod 125a are immovably fixed to each other, and hollows are formed.

한편, 도면에서 제1결합부(121)와 제2결합부(124)의 하부에 위치하는 제2파이프(126)와 제4파이프(128)의 단부에는 직경이 제2 및 제4파이프보다 넓은 제2수납부(127) 및 제4수납부(129)가 각각 결합된다. 상기 제2수납부(127) 및 제4수납부(129)도 이동이 불가능하게 고정되며, 각각 중공이 형성되어 있다.Meanwhile, in the drawings, diameters of the second pipe 126 and the fourth pipe 128 positioned under the first coupling part 121 and the second coupling part 124 are wider than that of the second and fourth pipes. The second accommodating part 127 and the fourth accommodating part 129 are respectively coupled. The second housing 127 and the fourth housing 129 are also immovably fixed, and hollows are formed.

조립부재(12)들의 결합시에, 상기 제2수납부(127) 및 제4수납부(129)에 상기 제1결합봉(122a) 및 제3결합봉(125a)이 각각 결합되며, 필요한 수만큼의 조립부재(12)들을 상하 결합함으로서 사다리의 길이를 증가 또는 감소시킬 수 있다.When the assembly members 12 are coupled, the first coupling rod 122a and the third coupling rod 125a are coupled to the second and fourth storage portions 127 and 129, respectively, By assembling the assembling members 12 up and down can increase or decrease the length of the ladder.

또한 본 발명에서는 조립된 사다리의 결합시 결합강도를 높이기 위하여, 탄성로프를 사용한다. 상기 탄성로프는 도 4를 참고하면, 제1결합부(121), 제1파이프(122), 제1결합봉(122a), 제2수납부(127)를 관통하여 연결되어 있다. 상기의 탄성로프(18)가 관통할 수 있도록 조립부재(12)의 각 구성요소에는 전부 중공이 형성되어 있음은 명백하다.In addition, in the present invention, in order to increase the coupling strength of the assembled ladder, an elastic rope is used. Referring to FIG. 4, the elastic rope is connected through the first coupling part 121, the first pipe 122, the first coupling rod 122a, and the second storage part 127. Obviously, all the components of the assembly member 12 are hollow so that the elastic rope 18 can penetrate.

탄성로프(18)는 도 2에서와 같이 사다리가 조립된 상태에서 흡입판(14) 또는 지지봉(16)을 결합하기 전에 수직방향으로 삽입하며, 탄성로프(18)의 양단부에 매듭을 형성하거나 핀을 이용하여 이동이 불가능하게 고정시킬 수 있다. 상기 탄성로프(18)는 조립식 사다리 본체(10)가 결합되면 인장력을 발휘하여 사다리 본체(10)를 사용할 때 외력에 의하여 사다리 본체(10)가 분리되지 않도록 충분한 강도를 갖는 것을 사용한다.The elastic rope 18 is inserted in the vertical direction before engaging the suction plate 14 or the support rod 16 in the assembled state, as shown in Figure 2, forming a knot or pins at both ends of the elastic rope 18 It can be fixed impossible to move using. When the prefabricated ladder body 10 is coupled to the elastic rope 18, it exhibits a tensile force so that it has sufficient strength so that the ladder body 10 is not separated by an external force when the ladder body 10 is used.

탄성로프(18)의 결합이 완료된 후에, 흡입판(14) 및 지지봉(16)을 각각 조 립식 사다리 본체(10)의 양단부에 결합한다.After the coupling of the elastic rope 18 is completed, the suction plate 14 and the support rod 16 are coupled to both ends of the assembled ladder body 10, respectively.

상기와 같이 내부에 탄성로프(18)가 연결된 본 발명의 조립식 사다리의 보관상태를 도 5를 참고하면 다음과 같다.Referring to Figure 5 the storage state of the prefabricated ladder of the present invention is connected to the elastic rope 18 therein as described above.

사다리의 조립부재(12)들은 각각 분리하면 조립부재(12)들은 분리되지만, 탄성로프(18)에 의하여 완전히 분리되지않는다. 이러한 상태에서 조립부재(12)들을 도면에서와 같이 겹친 상태에서 로프 또는 끈과 같은 것을 이용하여 일체로 묶어서 보관하는 것이 가능하다. 또한 폭이 커지더라도 조립부재(12)의 길이만큼 길이가 축소되기 때문에 휴대하기가 용이하다.When the assembly members 12 of the ladder are separated from each other, the assembly members 12 are separated, but are not completely separated by the elastic rope 18. In such a state, it is possible to store the assembly members 12 integrally by using a rope or a string in an overlapped state as shown in the drawing. In addition, since the length is reduced by the length of the assembly member 12 even if the width is easy to carry.

이와 같이 본 발명에 의하면 동일한 형태를 가진 다수의 조립부재를 이용하여 결합 및 분리가 용이하고, 사다리 결합후에도 조립부재들을 탄성로프를 이용하여 분리되지 않게 연결함으로서 단단하게 결합되며, 하단부에 흡입판을 결합시킴으로서 바닥에 대한 지지력이 높은 효과가 있다.As described above, according to the present invention, a plurality of assembly members having the same shape are easily coupled and separated, and even after the ladder is coupled, the assembly members are tightly coupled by using an elastic rope so as not to be separated, and the suction plate is provided at the lower end. By combining, there is a high effect of supporting the floor.
