Description
본 발명은 높이조절이 필요한 책상, 의자, 기구 등을 제조함에 있어 상부파이프가 하부파이프에 삽입되는 깊이에 따라 높이를 조절할 때 상부파이프와 하부파이프를 안전하고 견고하게 연결시켜주는 높이조절장치에 대한 기술로서, 특히 학교에서 사용하는 학생용 책상과 의자에 필수적인 부품으로 특별한 도구가 없이도 학생들이 자신들의 신체에 맞춰 높낮이를 조절할 수 있도록 만드는 가구용 높이조절장치에 대한 기술이다.The present invention relates to a height adjustment device that safely and firmly connects the upper pipe and the lower pipe when adjusting the height according to the depth at which the upper pipe is inserted into the lower pipe in manufacturing desks, chairs, appliances, etc. that require height adjustment. As a technology, it is an essential component of student desks and chairs used in schools, and is a technology for furniture height adjustment devices that allow students to adjust the height to suit their bodies without special tools.
학교에서 사용하는 학생용 책상, 의자, 기구 등은 평균적인 학생들의 신체 사이즈에 맞춰 제작되어 왔다. 그러나, 학생들의 성별, 영양상태, 유전인자 등에 따라 신체치수 및 체중변화에 따라 책상, 의자 치수표의 국가표준이 상향되어 더욱 편리하고 안전하며 견고한 높이조절을 요구하고 있다. Student desks, chairs, and equipment used in schools have been manufactured to fit the body size of average students. However, as body measurements and weight change according to students' gender, nutritional status, genetic factors, etc., the national standard for desk and chair size tables has been raised, requiring more convenient, safe, and sturdy height adjustment.
이와 관련된 종래기술로 본 출원인이 검색한 바에 의하면, 특허문헌에 기술한 특허문헌 1 내지 특허문헌 4 외에도 다수의 특허문헌이 개시되어 있는데, 종래의 기술은 상부파이프와 하부파이프의 한쪽 면만을 고정시켜, 상부파이프와 하부파이프 사이가 정밀하게 밀착되지 않으면 외부의 충력 등에 따라 상부파이프가 한쪽으로 쏠리는 현상이 발생하여 종국에는 책상 상판이나 의자 상판이 흔들리는 문제점이 있었다.According to the applicant's search for related prior art, in addition to Patent Documents 1 to 4 described in the patent literature, a number of patent documents are disclosed. The conventional technology fixes only one side of the upper pipe and the lower pipe. , If the upper pipe and the lower pipe are not tightly adhered, the upper pipe may be tilted to one side due to external force, which ultimately causes the desk or chair top to shake.
본 발명은 위와 같은 종래의 문제점을 고려하여 안출된 것으로서, 상부파이프와 하부파이프를 안전하고 견고하게 연결시켜주기 위하여 한쪽 면을 고정시키는 방식에서 벗어나 마주보는 양쪽 면을 각각의 조절핀과 안전핀을 사용하여 고정하는 장치를 만드는데 주된 목적이 있다. The present invention was developed in consideration of the above-described conventional problems. In order to safely and firmly connect the upper pipe and the lower pipe, instead of fixing one side, separate control pins and safety pins are used on both opposing sides. The main purpose is to create a fixing device.
학생용 책상, 의자, 기구 등은 기능성과 안전성을 함께 고려하여야 한다. 책상이 넘어지거나 외부의 충격이 있을 경우 상부파이프와 하부파이프 양쪽 면을 동일하게 고정함으로서 흔들림을 최소화하고, 학생들이 조절핀을 실수 또는 장난으로 당겼을 때 안전핀이 있어 책상상판 또는 의자상판이 내려가지 않도록 하는 안전장치가 포함되어야 한다.Student desks, chairs, and equipment must consider both functionality and safety. If the desk falls or there is an external impact, shaking is minimized by fixing both sides of the upper and lower pipes equally, and there is a safety pin to prevent the desk top or chair top from falling when students pull the control pin by mistake or as a joke. Safety devices must be included to prevent this.
또한, 신체치수와 체중에 맞춰 특별한 공구가 없이도 학생 스스로 책상, 의자, 기구 등의 높낮이 조절을 할 수 있어야 하는 과제가 있다.In addition, there is a task in which students must be able to adjust the height of desks, chairs, and equipment on their own without special tools according to their body size and weight.
전술한 문제점을 해결하기 위하여 안출된 본 발명은 상부파이프와 하부파이프를 동일한 간격으로 관통하도록 천공한 후, 하부파이프에 연결대를 끼워넣은 후, 상부파이프를 삽입하여 책상상판, 의자상판이 원하는 높이에 이르도록 상부파이프와 하부파이프의 관통홀이 일치되도록 한 후, 관통홀에 조절대의 조절핀을 삽입하여 상부파이프와 하부파이프가 아래 위로 움직이지 않도록 만든다. The present invention, which was developed to solve the above-mentioned problem, involves drilling holes through the upper pipe and lower pipe at equal intervals, inserting a connecting rod into the lower pipe, and then inserting the upper pipe so that the desk top and chair top are at the desired height. After ensuring that the through holes of the upper pipe and lower pipe are aligned, insert the control pin of the control bar into the through hole to prevent the upper pipe and lower pipe from moving up and down.
그런 후 반대편 관통홀에 안전대의 안전핀을 삽입하여 관통홀 양쪽을 모두 고정시켜주어 안전하고 견고하게 상부파이프와 하부파이프를 겹쳐 고정시켜주는 것을 특징으로 한다.Then, the safety pin of the safety belt is inserted into the opposite through hole to secure both sides of the through hole, safely and firmly overlapping and fixing the upper and lower pipes.
본 발명의 일 실시예에 따르면, 상부파이프와 하부파이프를 안전하고 견고하게 겹쳐 고정시킬 수 있어 책상, 의자, 기구 등의 높이를 조절할 때 사용할 수 있는 높이조절장치를 제조할 수 있으며, 이를 통해 학생들의 신체치수와 체중에 맞는 책상 또는 의자의 높이를 조절 할 수 있고, 외부충격시에도 상부파이프와 하부파이프가 이탈되는 것을 방지하는 내구성이 더욱 향상된 책상, 의자, 기구 등을 제조할 수 있다. According to one embodiment of the present invention, it is possible to manufacture a height adjustment device that can be used to adjust the height of desks, chairs, appliances, etc. by safely and firmly overlapping and fixing the upper pipe and the lower pipe, through which students can You can adjust the height of the desk or chair to suit your body size and weight, and you can manufacture desks, chairs, and equipment with improved durability that prevents the upper and lower pipes from coming off even in the event of external impact.
