In this case, the handle is installed inside the height adjusting device to determine the position of the upper brace and the handle is installed integrally to the rear side of the hook to facilitate assembly and to prevent the handle from being damaged. It is about.

일반적으로 학교에서 학생들이 사용하는 책, 걸상은 각 학년의 평균신장을 기준으로해서 3가지 형태로 크기가 상이하게 제작을 하여 사용하였기 때문에 평균신장을 가진 학생들은 책, 걸상을 사용함에 있어 큰 불편함이 없었으나, 신장이 크거나 작은 학생의 경우에는 책, 걸상을 사용하는데 불편함이 많았다.Generally, books and stools used by students in school are produced in three different sizes based on the average height of each grade, so students with average height have great inconvenience in using books and stools. There were no problems, however, in the case of tall or small students, it was inconvenient to use books and stools.

따라서, 상기와 같은 불편함을 제거하기 위해 책, 걸상의 높낮이를 조절할 수 있도록 하기 위하여 많은 높낮이 조절장치가 개발되었으며, 그 중 실용신안등록 제325099호가 있으나, 이는 높낮이 조절장치의 걸림봉과 손잡이가 각각 별도로 구성되어 있어 손잡이가 파손되는 경우가 빈번하게 발생하였다.Therefore, many height adjustment devices have been developed in order to adjust the height of books and stools to eliminate the inconvenience, there is a utility model registration No. 325099, which is the hook and handle of the height adjustment device, respectively Since it is configured separately, the handle is frequently broken.

즉, 상기 고안은 도 1에 도시한 바와 같이 책, 걸상의 양측에 설치된 지주를 상부지주와 하부지주로 분리하여 상부지주가 하부지주의 내부에 삽입되어 상, 하강되어 높낮이 조절장치에 의해 높낮이가 조절되도록 된 책, 걸상의 높낮이 조절장치에 있어서, 상기 높낮이 조절장치의 본체(1)에 하부지주가 삽입되는 지주삽입공(2) 을 형성하되, 상기 지주삽입공(2)의 상단에 하부지주의 상단이 걸리도록 걸림턱을 형성하고, 상기 본체(1)의 일측에는 안착홈(4)을 형성하되, 상기 안착홈(4)과 지주삽입공(2) 사이에는 관통공(5)을 형성하며, 상기 안착홈(4)에는 걸림돌기(8)가 돌출된 걸림봉(7) 및 스프링(9)을 설치한 후 덮개(6)을 씌워 볼트(11)로 고정한 구조로 되어 있었다.In other words, the design is to separate the struts installed on both sides of the book, the stool as the upper column and the lower column, as shown in Figure 1 so that the upper column is inserted into the lower column up and down to adjust the height by the height adjustment device In the height adjustment device of the book, the stool of the stool, forming a support insertion hole (2) into which the lower support is inserted into the main body (1) of the height adjustment device, but the upper end of the support is caught by the upper end of the support support (2). A locking jaw is formed so as to form a seating recess 4 at one side of the main body 1, and a through hole 5 is formed between the seating recess 4 and the support insertion hole 2. The groove 4 had a structure in which the locking bar 7 and the spring 9 protruding from the locking protrusion 8 were installed, and then the cover 6 was covered with the bolt 11 to fix it.

그리고 걸림봉(7)의 외측 끝단에는 손잡이(10)가 삽입되어 고정되는 삽입구(15)을 형성하고, 상기 삽입구(15)에는 손잡이(10)를 고정되도록 하였는데, 이는 손잡이(10)를 걸림봉(7)과 일체로 형성할 경우 덮개(6)의 안내공(3)을 통과할 수 없기 때문이었다.And the outer end of the locking rod (7) to form the insertion hole 15 is inserted into the handle 10 is fixed, the insertion hole 15 is to be fixed to the handle 10, which is the handle 10, the locking rod It was because it could not pass through the guide hole 3 of the cover 6 when formed integrally with (7).

따라서 걸림봉(7)의 삽입구(15)에 삽입되는 손잡이(10)의 직경이 가늘어 져 손잡이가 파손되는 경우가 빈번하게 발생하였을 뿐만 아니라 손잡이(10)가 걸림봉(7)으로부터 이탈되는 경우가 발생하였다.Therefore, the diameter of the handle 10 inserted into the insertion hole 15 of the catching rod 7 becomes thin and the handle is frequently broken, and the handle 10 is detached from the catching rod 7. Occurred.

또한, 높낮이 조절장치를 조립할 때 걸림봉(7)에 스프링(9)을 끼우고 덮개(6)의 안내공(3)에 삽입한 후 손잡이(10)를 걸림봉(7)의 삽입구(15)에 고정을 하였기 때문에 스프링의 탄력 때문에 덮개(6)와 걸림봉(7)을 동시에 잡고 손잡이를 고정(동시에 잡지 않을 경우 걸림봉이 덮개로부터 이탈됨)하여야 하였고, 손잡이(10)가 걸림봉(7)으로부터 잘 빠지지 않게 하기 위하여 걸림봉(7)의 삽입구(15)를 손잡이의 직경과 거의 동일하게 형성하기 때문에 손잡이(10)를 삽입구(15)에 끼우기가 매우 힘들었다.In addition, when assembling the height adjustment device by inserting the spring (9) to the engaging rod (7) and inserted into the guide hole (3) of the cover (6), the handle 10 is inserted into the insertion hole 15 of the engaging rod (7) Because of the spring's elasticity, it was necessary to hold the cover 6 and the catching rod 7 at the same time because of the elasticity of the spring, and fix the handle (when not caught at the same time, the catching rod is detached from the cover). Since the insertion hole 15 of the catching rod 7 is formed to be almost the same as the diameter of the handle so as not to fall out well, it was very difficult to insert the handle 10 into the insertion hole 15.

본 고안은 상기와 같은 제반 문제점을 제거하기 위하여 안출된 것으로서 걸림봉의 일측에 형성되는 손잡이가 이탈되거나 파손되는 것을 방지할 수 있을 뿐만 아니라 높낮이 조절장치의 조립을 용이하게 할 수 있는 책, 걸상용 높낮이 조절장치를 제공하는데 고안의 목적이 있다.The present invention has been devised to eliminate the above problems as well as preventing the handle formed on one side of the hanging bar from being separated or damaged, as well as the height of the book, stool for the height can be easily assembled It is an object of the invention to provide a control device.

상기 목적을 달성하기 위한 본 고안의 특징은 본체에 하부지주가 삽입되는 지주삽입공을 형성하되, 상기 지주삽입공의 상단에 하부지주의 상단이 걸리도록 걸림턱을 형성하고, 상기 본체의 일측에는 안착홈을 형성하되, 상기 안착홈과 지주삽입공 사이에는 관통공을 형성하며, 상기 안착홈에는 걸림봉 및 스프링을 설치한 후 덮개을 씌워 볼트로 고정한 높낮이 조절장치를 책, 걸상의 양측에 설치된 하부지주에 고정하고, 상부지주가 하부지주의 내부에 삽입되어 상, 하강되도록 한 책, 걸상의 높낮이 조절장치에 있어서, 상기 걸림봉의 외측 끝단에 손잡이를 걸림봉과 일체로 형성하고, 상기 걸림봉의 타측으로는 걸림링을 설치한 구조로 된 것으로서 이하 첨부된 도면에 의거하여 본 고안의 구성을 상세히 설명하면 다음과 같다.A feature of the present invention for achieving the above object is to form a support insertion hole is inserted into the lower column in the main body, to form a locking jaw to take the upper end of the lower column in the upper end of the support insertion hole, the mounting groove on one side of the body To form a through-hole between the seating groove and the holding insertion hole, the seating groove is installed on the lower supports installed on both sides of the book, the height of the height adjustment device is fixed to the cover bolts after installing the locking rod and the spring In the height adjustment device of the book, the stool is fixed, and the upper brace is inserted into the lower brace to move up and down, the handle is formed integrally with the catching rod at the outer end of the catching rod, and the catching ring on the other side of the catching rod. The structure of the present invention will be described in detail with reference to the accompanying drawings as follows.

도면에 도시된 바와 같이 본체(1)에 책, 걸상의 하부지주가 삽입되는 지주삽입공(2)을 형성하고, 상기 본체(1)의 일측에는 걸림봉(20)이 설치되는 안착홈(4)을 형성하되, 상기 안착홈(4)과 지주삽입공(2) 사이에는 관통공(5)을 형성하며, 상기 안착홈(4)에는 걸림봉(20) 및 스프링(9)을 설치한 후 안내공(3)이 형성된 덮개(6) 을 씌워 볼트(11)로 고정한 책, 걸상의 높낮이 조절장치에 있어서, 상기 걸림봉(20)의 외측 끝단에 손잡이(21)를 걸림봉(20)과 일체로 형성하고, 상기 걸림봉(20)의 타측으로는 걸림돌기(22)를 돌출시켜 걸림링(23)을 삽입 고정한다.As shown in the drawing, the main body 1 has a support insertion hole 2 into which a book and a lower supporter of a stool are inserted, and a seating groove 4 having a locking rod 20 at one side of the body 1 is installed. Although forming a through-hole (5) between the seating groove (4) and the support insertion hole (2), the seating groove (4) guides after installing the engaging rod 20 and the spring (9) In the height adjusting device of the book and the stool, which is covered with a cover 6 having a ball 3 formed thereon, the handle 21 is integrated with the catching rod 20 at the outer end of the catching rod 20. It is formed as, the other side of the locking rod 20 is projected by the locking projection 22 to insert the locking ring 23 is fixed.

이때, 상기 걸림봉(20)의 걸림돌기(22)는 테이퍼지게 형성하여 걸림링(23)을 걸림봉(20)에 삽입 고정할 때 삽입이 용이하게 하고, 삽입이 된 뒤에는 걸림돌기(22)에 걸림링(23)이 걸려 이탈이 되지 않도록 한다.At this time, the locking protrusion 22 of the locking rod 20 is tapered to facilitate insertion when the locking ring 23 is fixed to the locking rod 20, and the locking protrusion 22 is inserted thereafter. The locking ring 23 is caught so as not to be separated.

이상과 같이 구성된 본 고안은 걸림봉(20)을 덮개(6)의 안내공(3)에 끼운 다음 스프링(9)을 걸림봉(20)에 삽입한 후 걸림링(23)을 걸림봉(20)에 삽입 고정하고, 덮개(6)를 본체(1)에 고정시키면 조립이 완료된다.The present invention configured as described above is inserted into the guide hole (3) of the cover (6) and then inserting the spring (9) to the catching rod (20), the catching ring (23) catching rod (20) ), And assembly is completed by fixing the lid 6 to the main body 1.

즉, 걸림봉(20)에 걸림링(23)을 고정할 때 걸림돌기(22)가 테이퍼져 있고, 걸림돌기(22)의 외경중 큰 외경이 걸림링(23)의 내경보다 약간 크게 형성되어 있어 삽입을 할 때는 조금 힘을 가하면 삽입(재질이 합성수지로 형성되어 있어 약간 압축되었다가 원위치 됨)이 되나, 한번 삽입된 걸림링(23)은 걸림돌기(22)가 훼손되지 않는 한 이탈되지 않게 된다.That is, when the locking ring 23 is fixed to the locking bar 20, the locking protrusion 22 is tapered, and a larger outer diameter of the outer diameter of the locking protrusion 22 is slightly larger than the inner diameter of the locking ring 23. When inserting, when a little force is applied, it is inserted (the material is made of synthetic resin, so it is slightly compressed and then returned to its original position), but the locking ring 23 once inserted is not detached unless the locking protrusion 22 is damaged. do.

따라서 종래에는 걸림봉에 손잡이를 고정하기 위하여 덮개와 걸림봉을 동시에 잡고 직경이 적은 걸림봉에 손잡이를 고정해야 하므로 작업이 어려웠고, 손잡이가 이탈되거나 부러지는 등의 폐단이 있었으나, 본 고안은 내측으로 길게 형성되어 있는 걸림봉(20)에 스프링(9)과 걸림링(23)을 삽입하게 되므로 스프링의 탄성력에 영향을 받지 않게 되고, 걸림링(23) 또한 길게 형성된 걸림봉(20)에 일단 삽입한 후 걸림돌기(22)에 걸리도록 하였기 때문에 조립이 용이하고, 손잡이(21)가 걸 림봉(20)과 일체로 형성되어 있기 때문에 이탈되거나 훼손이 되지 않게된다.Therefore, in the prior art, it was difficult to work because it was necessary to hold the cover and the locking rod at the same time to fix the handle to the locking rod and to fix the handle to the locking rod with a small diameter, and there was a closed end such as detaching or breaking the handle. Since the spring 9 and the locking ring 23 are inserted into the locking bar 20 that is formed long, the spring 9 and the locking ring 23 are not affected by the elastic force of the spring. Since it is easy to assemble because it is caught by the locking projection 22, since the handle 21 is formed integrally with the locking rod 20, it is not separated or damaged.

이상과 같은 본 고안은 걸림봉의 일측에 형성되는 손잡이가 이탈되거나 파손되는 것을 방지할 수 있을 뿐만 아니라 높낮이 조절장치의 조립을 용이하게 할 수 있는 등의 효과가 있는 것이다.The present invention as described above is to prevent the handle formed on one side of the locking rod is separated or damaged, as well as to facilitate the assembly of the height adjustment device.
