본 고안은 의자를 필요에 따라 사다리로 전환시켜 사용할 수 있는 사다리 겸용의자에 관한 것이다.The present invention relates to a ladder combined chair that can be used to convert the chair into a ladder as needed.

통상 일반가정에서는 주로 낮은 사다리를 필요로 하였으므로 별도로 구입하여 보관하여야 하는 낭비와 불편이 있었다.In general, since a general ladder needed a low ladder, there was a waste and inconvenience to be stored separately.

본 고안에서는 이와 같은 폐단을 없애고져 의자의 앞다리를 계단식으로 층대를 부착시키고 이와는 별도로형의 상부다리를 앞다리의 상단과 연결편으로 연결시켜 의자로 사용시에는 상부사다리를 앞다리내로 절첩시키고 사다리로 사용시에는 연결편을 이용하여 상부다사리를 의자 좌판의 상부로 전재시켜 사다리로 구성되도록 된 것으로 도면에 의거 상세히 설명하면 다음과 같다.In the present invention, such a closed end is eliminated, and the front leg of the chair is attached to the floor by cascading, The upper leg of the mold is connected to the upper part of the front leg by connecting the upper ladder into the front leg when using it as a chair, and when using it as a ladder, the upper leg is transferred to the upper part of the chair seat by using the connecting piece. The detailed description is as follows.

좌판의 양측골조(10)를 연결하는 후부연결대(11)에 좌판(1)을 상하부로 유동되게 축착시키고 앞다리골조(20)의 상부쪽에는 후부연결대(21)로서 층대(22)를 형성시키고 앞다리 골조의 상단(20')에는 연결편(2)을 핀축시켜서 중간 연결대(31)와 하단연결대(33)로서 층대(32), (34)가 형성된형의 상부사다리(30)를 상부골조(35)의 내측단(35')과 외측에서 연결축(37)으로 축착시켜서 상부사다리가 앞다리 내부로 절첩시에는 연결핀(2)과 외측에서 축착된 연결축(37)의 양외측돌출단(37')이 좌판의 양측골조(10)의 전부에 형성된 상부홈(10')에 걸리고 상부사다리의 하부내측연결대(33)는 좌판골조의 중간연결대(12)와 다리골조의 하부연결대(23)를 연결하는 중앙종대(24)에 부착된 스프링걸고리(25)로서 고정되도록 하였으며 상부사다리를 앞다리골조의 상단과 연결된 연결편을 중심으로 상부로 전개시에는 상부사다리의 상부양골조(35) 전부에 형성된 양쪽홈(36)에 좌판골조의 후부연결대(11)에 형성된 양쪽돌기(11')가 끼워지도록 구성된 것으로 미설명부호(1')는 좌판저면의 돌기이고 (38), (38')는 이 돌기가 삽입될 전부연결대의 삽입홈이다.The seat plate 1 is fixed to the rear connector 11 connecting the two side frames 10 of the seat plate to the upper and lower parts, and the upper side of the front leg frame 20 forms a layer 22 as a rear connector 21 on the front leg and the front leg. The upper end 20 'of the frame is pinned to the connecting piece 2 to form a layered bed 32, 34 as the intermediate connecting rod 31 and the lower connecting rod 33. The upper ladder 30 of the mold is condensed from the inner end 35 'and the outer side of the upper frame 35 to the connecting shaft 37 so that when the upper ladder is folded into the front leg, it is condensed from the connecting pin 2 and the outside. Both outer protruding ends 37 'of the connecting shaft 37 are caught in the upper groove 10' formed in all of the two side frames 10 of the seat plate, and the lower inner connecting rod 33 of the upper ladder has an intermediate connector ( 12) and the spring hook (25) attached to the central longitudinal belt 24 for connecting the lower connector 23 of the leg frame, and fixed to the upper ladder when deployed to the upper center of the connection piece connected to the upper end of the foreleg frame Both grooves 36 formed on the upper both skeletons 35 of the ladder are configured to fit both projections 11 'formed on the rear connecting rod 11 of the seat plate frame, and the reference numeral 1' is a projection of the bottom plate. And (38) and (38 ') are the insertion grooves of all the connecting rods into which these projections are to be inserted.

이와 같은 구조로 된 본 고안은 의자의 앞다리골조(20)에 후부 연결대(21)를 부착시켜 층대(22)을 형성시키고 앞다리골조의 상단(20')에는 중, 하연결대(31), (33)로서 층대(32), (34)를 형성시킨형의 상부사다리(30)를 상하부로 전개 또는 절첩되게 연결편(2)으로 연결시켰으므로 의자로 사용시에는 상부사다리를 하향으로 절첩시켜 상부사다리의 상부 골조내측단(35')이 연결편(2)과 외측에서 연결측(37)으로 축착되어 양측으로 돌출된 양외측돌출단(37')이 좌판의 양측골조(10) 전부에 형성된 상부홈(10')에 걸리도록 하고 상부사다리의 하부내측연결대(33)는 좌판골조의 중간연결대(21)와 다리골조의 하부연결대를 연결하는 중앙종대(24)에 부착된 스프링걸고리(25)로서 고정시켜 상부사다리를 의자의 앞다리 내부로 삽입시켜 상, 하부에서 고정시켰으므로 의자로 사용시 상부사다리가 이완되는 일이 없고 이 좌판골조와 평행으로 결합된 상부사다리의 상부에 등판쪽으로 제쳐 놓은 좌판(1)을 하향으로 얹으면 좌판저면의 돌기(1')가 상부사다리상부의 전부연결대(38)에 형성된 삽입홈(38')에 끼워져서 의자로 사용되며 사다리로 사용시에는 스프링걸고리(25)에 걸려 있는 상부 사다리의 하부내측연결대(33)를 이탈시켜 상단에 연결된 연결편을 이용하여 상부사다리를 좌판골조의 상부로 얹어놓으면 상부사다리의 상부 양골조(35) 전부에 형성된 양쪽홈(36)에 좌판골조의 후부연결대(11)에 형성된 양쪽돌기(11')가 끼워지면서 유동성이 없고 높이가 의자좌판의 2배가 되는 사다리가 구성되고 의자의 앞다리골조의 상부쪽층대(22)와 상부사다리의 중간부와 하단에 형성된 층대(32), (34)로서 사다리가 완성되는 것이다.The present invention having such a structure is attached to the rear connecting frame 21 to the front leg frame 20 of the chair to form a layer 22, and the upper and lower connecting bars 31, 33 (33) ) To form the floors 32 and 34 Since the upper ladder 30 of the type is connected to the connecting piece 2 so as to be deployed or folded up and down, when used as a chair, the upper ladder is folded downward to allow the upper frame inner end 35 'of the upper ladder to connect with the connecting piece 2. Both outer protrusions 37 'protruding from both sides to the connection side 37 and protruding to both sides are caught by the upper groove 10' formed on both sides of the frame 10 of the seat plate, and the lower inner connecting rod of the upper ladder ( 33) is fixed as a spring hook (25) attached to the central belt (24) connecting the middle connector 21 of the seat plate frame and the lower connector of the leg frame to insert the upper ladder into the front leg of the chair upper and lower Since the upper ladder does not relax when used as a chair, and when the seat plate (1) aside from the back is placed on the upper part of the upper ladder coupled in parallel with the seat frame, the projection (1 ') of the bottom of the seat is upper The upper part of the ladder It is used as a chair by being inserted into the insertion groove 38 'formed in the sub-connection 38. When using as a ladder, the lower inner connecting rod 33 of the upper ladder hanging on the spring hook 25 is separated to use the connecting piece connected to the top. When the upper ladder is placed on the upper part of the seat plate frame, both grooves 36 formed on all of the upper both frames 35 of the upper ladder are fitted with both protrusions 11 'formed at the rear connecting rod 11 of the seat plate frame. Ladder that is double the height of the chair seat is configured, and the ladder is completed as the upper floor layer 22 of the front leg frame of the chair and the floors 32 and 34 formed at the middle and lower portions of the upper ladder.
