Description

학생용 책상 및 걸상의 높낮이 조절장치{REGULATION DEVICE OF DESK AND CHAIR FOR STUDENT}Height adjustment device for student desk and stool {REGULATION DEVICE OF DESK AND CHAIR FOR STUDENT}

본 발명은 학생용 책상 및 걸상의 높낮이를 용이하게 조절할 수 있도록 한 높낮이 조절장치에 관한 것으로서, 좀더 구체적으로는 학생용 책상 및 걸상의 양측에 형성된 지주를 상하로 분리하여 형성한후 높낮이 조절장치를 상기 지주에 설치하여 책상 및 걸상의 높낮이를 조절하도록 한 높낮이 조절장치에 있어서, 상기 높낮이 조절장치의 구조를 간단히 하여 책상 및 걸상의 높낮이 조절을 손쉽게 할 뿐만 아니라, 설치를 용이하게 하여 제조원가를 절감하도록 한 것에 관한 것이다.The present invention relates to a height adjustment device that can easily adjust the height of the student desk and the stool, and more specifically, formed by separating the struts formed on both sides of the student desk and the stool up and down, the height adjustment device is the post A height adjustment device to adjust the height of the desk and the stool to be installed in, the structure of the height adjustment device to simplify the height adjustment of the desk and the stool, as well as to facilitate the installation to reduce the manufacturing cost 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 제안된 것으로서 일본국 실용신안 공개 소49-30201호(1974. 3. 15 공개) 및 소56-125739호(1981. 9. 25 공개)등이 있었으나 이는 구조가 복잡하여 설치에 어려움이 많아 책, 걸상의 제조원가가 상승되는 문제점이 있었다.Therefore, the Japanese Utility Model Publication Nos. 49-30201 (published on March 15, 1974) and 56-125739 (1981. 9. 25 Disclosure), but it is difficult to install due to the complicated structure, which increases the manufacturing cost of books and stools.

즉, 전자인 소49-30201호는 상부 지주에 높낮이 조절장치를 설치하기 위해서는 상부지주의 일부를 절곡시킨후 상기 절곡부위에 높낮이 조절장치를 고정시키고, 하부지주에는 걸림봉의 이동을 제한시키기 위해 하부지주를 내측으로 절곡시켜야 하였기에 상, 하부 지주의 가공에 어려움이 많아 제조원가가 상승되었을 뿐만 아니라 상부지주에 높낮이 조절장치를 고정하기 위해서는 용접등을 해야 하였기 때문에고정에 어려움이 많았다.That is, the former, 49-30201, bends a part of the upper column to install the height adjusting device on the upper support, and then fixes the height adjusting device to the bent portion, and the lower part has a lower portion to limit the movement of the rod. Since the shores had to be bent inward, the manufacturing cost was increased due to the difficulty in processing the upper and lower shores, and it was difficult to fix them because welding had to be performed to fix the height adjusting device to the upper lands.

그리고, 후자인 소56-125739호 역시 하부지주의 길이방향 중앙을 절개한후 상기 절개된 하부지주 사이에 걸림봉의 이동이 제한되도록 경사면이 형성된 판재를 설치하였고, 상부지주에 높낮이 조절장치를 용접으로 고정하였기 때문에 이또한 높낮이 조절장치를 설치하기 위한 공정이 복잡하여 제조원가가 상승되는 문제점이 있었다.In addition, the latter No. 56-125739 also installed the inclined surface plate to limit the movement of the engaging rod between the inferior lower column after cutting the longitudinal center of the lower column, and fixed the height adjustment device to the upper column by welding Since the process for installing the height adjusting device is also complicated, there was a problem that the manufacturing cost is increased.

본 발명은 상기와 같은 제반 문제점을 제거하기 위하여 창출된 것으로서 높낮이 조절장치를 책, 걸상의 좌우지주에 손쉽게 설치할 수 있도록 함으로써 책, 걸상의 제조원가를 절감하는데 발명의 목적이 있다.The present invention has been made in order to eliminate the above problems, the purpose of the invention is to reduce the manufacturing cost of the book, the stool by allowing the height adjustment device to be easily installed on the left and right supports of the book, the stool.
