본 고안은 높이와 천판의 경사도를 임의로 조절할 수 있는 절찹식 책상다리를 제공하기 위한 것이다.The present invention is to provide a chopped desk legs that can arbitrarily adjust the height and inclination of the top plate.

종래에도 책상의 높이를 조절하기 위한 각종의 고안의 안출된바 있으나 이와 같은 종래의 책상들은 높이 조절 책상에서 특히 요구되는 조절의 간편성과 견고성이 부족하여 크게 실용화되지 못한 상태에 있었던 것이다. 그리하여 성장속도가 빠르고 개인차가 극히 심한 각급학교 학생들은 체격에 맞지 않는 책걸상을 사용하는 일이 보통이어서 빠른자세를 유지하는데에 많은 지장을 초래할 뿐 아니라 성장을 방해하고 섬지어 척추가 구부러지는 등의 폐단이 있었으나 성장에 따른 책걸상의 교체에는 막대한 비용을 요하게되어 사실상 같은 칫수의 책걸상을 수년간씩이나 사용할 수 밖에 없었던 것이다.Conventionally, various designs have been devised for adjusting the height of the desk, but such conventional desks have been in a state of not being practically used due to the lack of simplicity and robustness, which are particularly required for height adjustment desks. As a result, students in various schools with high growth rate and extremely high individual differences usually use a non-physical bench, which not only causes a lot of problems in maintaining a fast posture, but also prevents growth and causes the spine to bend. There was, however, a huge cost to replace a tabletop with growth, and had to use the same tabletop for many years.

본 고안은 구조를 단순화시키므로서 취약성을 보강하였으며 연결 절첩부의 구조를 강건히하여 사용중 파손이 되는 것을 방지 하였고 다리를 2단 절첩할 수 있게 하므로서 높이 조절은 물론 천판의 경사각도를 조절하여 제도용책상, 화판등으로도 사용할 수 있도록 하였다.This design strengthens the fragility by simplifying the structure, strengthens the structure of the connecting folds, prevents damage during use, and enables two-fold folding of the legs, thereby adjusting the height of the top plate and adjusting the inclination angle of the top plate. It can also be used as a drawing board.

물론 본 고안의 책상다리는 걸상에도 그대로 적용될수 있으며, 책상만이 아니라 걸상의 높이도 체격의 성장에 따라 조절하여야 하므로 걸상에 있어서는 높이 조절도 책상과 같은 비중으로 중요성을 가진다.Of course, the desk leg of the present invention can be applied to the bench as it is, and the height of the stool as well as the desk should be adjusted according to the growth of the physique, so the height adjustment on the stool has the same importance as the desk.

본 고안의 구성등을 첨부도면에 의하여 설명하면 다음과 같다.Referring to the configuration of the present invention by the accompanying drawings as follows.

기틀(1)의 상부 중심에 연결간(4)의 일단을 축설하고 그 타단에 ㄱ자형의 저지틀(3)을 축설한다. 기틀(1)과 연결간(4), 연결간(4)과 지지틀(3)을 축설시키는 각 연결부의 구조는 동일하며 그 구조를 상세히 설명하면 다음과 같다.One end of the connecting rod 4 is laid in the upper center of the base 1, and an L-shaped jersey frame 3 is laid in the other end thereof. The structure of each connection part which arranges the base 1 and the connection 4, the connection 4, and the support frame 3 is the same, and the structure is demonstrated in detail as follows.

기틀(1)의 연결단부(1')를중공상으로 하고 이에다수개의 연결판(5)과 와셔(6)를 교호로 적층시킨 연결구(가)를 리벳트(7)로 고착시킨다.The connecting end 1 'of the frame 1 is hollowed out, and a connector (A) in which a plurality of connecting plates 5 and washers 6 are alternately laminated is fixed with a rivet 7.

연결핀(5)과 와셔(6)의 두께는 동일한 것이 이상적이며 와셔(6)의 길이보다는 연결편(5(의 길이가 커서 연결편(5)과 연결편(5)사이의 공간으로 연결간(4)의 연결편(8)이 감입되어 교합되도록 한다. 각 연결편(5)의 중심에는 축공(5')이 형성되어 있으며 축공(5")을 중심으로 하는 동심 원주상에 등간격으로 다수개의 교합공(5")을 천설시킨다.Ideally, the thickness of the connecting pin 5 and the washer 6 is the same, and the space between the connecting piece 5 and the connecting piece 5 is greater than the length of the washer 6 so that the connecting piece 5 is larger. The connecting piece 8 is inserted into and interlocked with each other. A shaft hole 5 'is formed at the center of each connecting piece 5, and a plurality of occlusal holes are formed at equal intervals on the concentric circumference centering on the shaft hole 5 ". 5 ").

그리고 연결간(4)의 단부 역시 중공상으로 하고 그 중공내부에도 연결편(8)과 와셔(9)를 교호로 적층시킨 연결구(나)를 리벳트(10)로 고착시킨다. 연결구(나)의 각연결편(8)의 중심에도 축공(8')이 천설되어 있고 축공(8')의 주위에는 연결구 (가)의 연결편(5)에 형성된 교합공(5")에 대응하는 크기와 위치를 갖는 돌기(8")가 형성되어 있다.And the end of the connecting rod 4 is also hollow, and the connector (B) in which the connecting piece 8 and the washer 9 are alternately laminated in the hollow is also fixed by the rivet 10. A shaft hole 8 'is also provided in the center of each connecting piece 8 of the connector (b), and around the shaft hole 8' corresponding to the occlusal hole 5 "formed in the connecting piece 5 of the connector (a). A projection 8 "having a size and a position is formed.

따라서 기틀(1)과 연결간(4), 연결간(4)과 지지틀(3)을 각각 연결시킬 경우 연결구 (가)와 연결구 (나)를 각각 교합시키고 축공(5')(8')에 축봉(11)을 끼워 축설시킬 수 있는 것이다. 이와 같이 연결구 (가)(나)를 축봉(11)으로 축설하되 교합되고 축설된 연결구 (가)(나)의 연결편(5)(8)을 밀착되게 압착시키면 연결편(5)의 교합공(5")에 다른 연결편(8)의 돌기가 감합되어 회동치 아니하게 되나 연결편(5)(8)을 약간 느슨히 하면 회동되므로 다리를 펼치고 접을 수 있게되는 것이다.Therefore, when connecting the frame (1) and the connection between the connection (4), between the connection (4) and the support frame (3), respectively, mating the connector (A) and the connector (B), respectively, and the shaft hole (5 ') (8') The shaft 11 can be inserted into the shaft. In this way, the connector (A) (B) is laid in the shaft (11), but when the mating and crimping the connecting piece (5) (8) of the connector (A) (B) to be in close contact with the occlusal hole (5) ") Fits the projections of the other connecting piece (8) is not rotated, but if you loosen the connecting piece (5) (8) slightly will be able to expand and fold the legs.

두개의 연결구 (가)(나)를 연결 한후 이들을 조이고 푸는 기술적 수단은 여러가지를 생각할 수 있으나 본 고안에서는 제3도에 도시된 바와 같이 좌우기틀(1)의 사이에 또 좌우 지지틀(3)의 사이에 저지용 파이프 즉 저지관체(12)를 개재시키고 저지관체(12)내부로 축봉(11)을 끼워 장착하므로서 일측에서 조이고 풀면 양측의 연결부가 조여지고 풀어지게 하였으며 저지관체(12)와 축봉(11)이 두개의 기틀(1)을 결착시켜 견고성을 증가시킬 수 있도록 하였다.After connecting the two connectors (A) and (B), various technical means for tightening and releasing them can be considered. However, in the present invention, as shown in FIG. 3, the left and right support frames 3 are disposed between the left and right frameworks 1. Interlocking pipes, that is, intervening the stopping pipe body 12, sandwiching the shaft rod 11 into the stopping pipe body 12, and tightened from one side to loosen and loosened the connection parts of both sides, the stop pipe body 12 and the shaft ( 11) the two frameworks (1) were bonded to increase the robustness.

도면중 미설명부호 13은 나비 너트이다.Reference numeral 13 in the drawings is a butterfly nut.

이와 같이 구성된 본 고안은 나비너트(13)를 풀면 연결편(5)(8)의 밀착상태가 해이되어 두개의 연결구(가)(나)가 축봉(11)을 중심으로 회동될 수 있으며 따라서 기틀(1)과 연결간(4) 및 연결간(4)과 지지틀(3)을 각각 회동시키므로서 다리를 펼치고 접을수 있을뿐 아니라 지지틀(3)에 부착된 천판의 각도를 수평으로도 할수 있고 직립)수직)으로도 할수 있으며 경사지계도 할수 있게되는 것이다.According to the present invention configured as described above, when the butterfly nut 13 is loosened, the contact state of the connecting pieces 5 and 8 is detrimental, so that two connectors (a) can be rotated about the shaft 11 and thus the frame ( 1) and connecting (4) and connecting (4) and the support frame (3) by rotating the legs can be extended and folded, as well as the angle of the top plate attached to the support frame (3) can be horizontally Orthogonal) or vertical slope.

따라서 본 고안의 책상다리는 의자, 책상, 칠판, 화가, 교탁등 각종의 가구에 널리 사용될수 있으며 특히 학교용 책걸상으로 사용할 경우에는 성장에 따른 높이 조절이 용이하고 또 미술시간에는 화가로도 사용할 수 있어 용도의 다양화도 겸할수 있는 효과가 있다.Therefore, the desk leg of the present invention can be widely used in various furnitures such as chairs, desks, blackboards, painters, school tables, etc. Especially when used as a school desk, the height can be easily adjusted according to growth and used as a painter during art class. It also has the effect of diversifying the use.
