Description
본 고안은 학생용 책상 및 걸상의 높낮이를 용이하게 조절할 수 있도록 한 높낮이 조절장치에 있어서, 상부지주를 지지하고 있는 걸림봉이 상부지주에 반복적으로 가해지는 하중에 의해 자연적으로 후퇴하는 것을 방지하도록 한 것에 관한 것으로서, 좀더 구체적으로는 학생용 책상 및 걸상의 양측에 형성된 지주를 상하로 분리하여 형성한 후 높낮이 조절장치를 상기 지주에 설치하여 책상 및 걸상의 높낮이를 조절하도록 하고, 상기 높낮이 조절장치의 내부 안착홈에 걸림봉을 설치하여 덮개를 고정하여 상기 걸림봉이 상부지주의 상,하강을 제한하도록 된 높낮이 조절장치에 있어서, 상기 덮개에는 암나사산을 형성하고, 상기 걸림봉의 내측단에는 숫나사산을 형성하여 걸림봉이 덮개에 나사결합되어 있어 걸림봉이 후진하는 것을 방지하도록 한 것에 관한 것이다.The present invention relates to a height adjustment device for easily adjusting the height of a student desk and a stool, to prevent the catch rod supporting the upper column from being naturally retracted by a load repeatedly applied to the upper column. As more specifically, after forming the upper and lower support posts formed on both sides of the student desk and the stool up and down, the height adjustment device is installed on the support to adjust the height of the desk and the stool, and the inner seating groove of the height adjustment device In the height adjustment device for fixing the cover by fixing the cover by installing a locking rod in the upper rod, the female thread is formed on the cover, the inner end of the locking rod is formed by forming a male thread The rod being screwed into the cover to prevent the catch rod from reversing It relates.
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 본 고안의 출원인이 고안한 실용신안등록 제212,306호가 있으나, 이는 책상 및 걸상의 높낮이를 용이하게 조절할 수 있는 장점은 있으나, 책상의 상판 및 걸상의 좌판에 반복하여 하중이 작용할 경우 걸림봉이 조금씩 후퇴하여 나중에는 걸림봉이 상부지주를 완전히 벗어나 상부지주가 자연적으로 하강하는 문제점이 있었다.Therefore, there is a utility model registration No. 212,306 designed by the applicant of the present invention in order to adjust the height of a book and a stool to eliminate the inconvenience, but this is an advantage that can easily adjust the height of the desk and stool However, if the load is repeatedly applied to the upper plate of the desk and the seat of the stool, there is a problem that the catch rod retreats little by little, and later, the catch rod completely escapes the upper column and the upper column naturally descends.
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 설치한후 덮개(6)을 씌워 볼트(11)로 고정한 구조로 되어 있었기 때문에 상부지주에 반복적으로 하중이 작용할 경우 걸림봉(7)이 조금씩 후퇴하게 되었다.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. Since 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 fixed to the bolt 11 to fix the bolt 11, In this case, the catching rod 7 retreats little by little.
즉, 상기의 발명은 걸림봉(7)이 스프링(9)의 의 탄성력에 의존하여 지지되어 있어 스프링(9)이 걸림봉(7)을 계속하여 전진시키고자 하여 걸림봉이 후퇴되지 않을 것 같으나, 상부지주에는 항상 하중이 가해지게 되고 특히, 걸상의 경우에는 사람이 앉았다 일어났다를 하여 반복적으로 하중이 가해지게 되고, 걸림봉(7)은 상부지주에 의해 압력이 가해진 상태이기 때문에 조금이라도 한번 후퇴를 하면 전진을 하지 못하게 됨으로 책상의 상판 및 걸상의 좌판은 시간이 경과함에 따라 자연적으로 하강을 하여 재차 책, 걸상의 높낮이를 조절해야 하는 문제점이 있었다.That is, in the above invention, the catching rod 7 is supported depending on the elastic force of the spring 9 so that the catching rod 7 does not seem to retreat in order to continue to advance the catching rod 7. A load is always applied to the upper column, and in particular, in the case of a stool, a load is repeatedly applied when a person sits up and rises, and the latching rod 7 is retracted at least once because the pressure is applied by the upper column. If you do not move forward because the top of the desk and the seat of the stool has a problem to adjust the height of the book, stool again to descend naturally over time.
본 고안은 상기와 같은 제반 문제점을 제거하기 위하여 안출된 것으로서 높낮이 조절장치의 걸림봉 및 덮개에 나사산을 형성하여 책, 걸상의 높낮이 조절을 한번 하면 자연적 높낮이가 변하지 않도록 한 책, 걸상용 높낮이 조절장치를 제공하는데 고안의 목적이 있다.The present invention has been made to eliminate the above problems as a screw thread formed on the hanging rod and the cover of the height adjusting device to adjust the height of the book, the stool, so that the natural height does not change, the height adjustment device for the stool The purpose of the devised to provide.
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 내측단에 숫나사산을 형성하고, 상기 덮개에는 암나사산을 형성하여 상기 숫나사산이 암나사산에 결합되도록 한 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 column is inserted into the lower column up and down, the male thread is formed on the inner end of the engaging rod, and the female thread is formed on the cover. As it is to be coupled to the female screw thread, the configuration of the present invention in detail based on the accompanying drawings as follows.
도 2 및 도 3에 도시한 바와 같이 본체(1)에 책, 걸상의 하부지주가 삽입되는 지주삽입공(2)을 형성하고, 상기 본체(1)의 일측에는 걸림봉(7)이 설치되는 안착홈(4)을 형성하며, 상기 안착홈(4)과 지주삽입공(2) 사이에는 관통공(5)을 형성한다.As shown in Fig. 2 and 3, the main body 1 is formed with a support insertion hole (2) into which the lower column of the book and the stool is inserted, and a seating rod (7) is installed on one side of the main body (1). A groove 4 is formed, and a through hole 5 is formed between the seating groove 4 and the support insertion hole 2.
그리고 상기 안착홈(4)에는 걸림봉(27)을 스프링(9)으로 탄력있게 설치한 후 덮개(6)을 씌워 볼트로 고정한다.Then, the mounting groove (4) is securely installed with a bolt (6) and then cover the cover (6) after the resilient rod 27 is installed elastically with a spring (9).
이때, 상기 덮개(6)에는 암나사산(15)을 형성하고, 상기 걸림봉(7)의 내측단에 숫나사산(16)을 형성하여 상기 숫나사산(16)이 암나사산(15)에 결합되도록 한다.At this time, the cover 6 is formed with a female thread 15, a male thread 16 is formed on the inner end of the engaging rod 7 so that the male thread 16 is coupled to the female thread 15. do.
이상과 같이 구성된 본 고안은 책, 걸상의 높낮이를 조절한 후 걸림봉(7)을 전진시킨 후 회전시키면 걸림봉(7)의 숫나사산(8)이 덮개(6)의 암나사산(9)에 결합되면서 전진을 하게 됨으로 걸림봉(7)을 회전시키지 않는 한은 자연적으로 후진을 하지 않게 되는 것이다.According to the present invention configured as described above, after adjusting the height of the book and the stool, the hook rod 7 is moved forward and rotated so that the male thread 8 of the hook rod 7 is attached to the female thread 9 of the cover 6. Combination is to move forward as long as you do not rotate the hook (7) will not naturally reverse.
이상과 같은 본 고안은 높낮이 조절장치의 걸림봉 및 덮개에 나사산을 형성하여 책, 걸상의 높낮이 조절을 한번 하면 자연적 높낮이가 변하지 않게 되는 효과가 있는 것이다.The present invention as described above is to form a screw thread on the hanging bar and the cover of the height adjustment device once the height adjustment of the book, the stool has the effect that the natural height does not change.
