Description

책걸상 다리높이 조절장치{Height adjustable legs of desk and chair}Height adjustable legs of desk and chair}

본 발명은 책걸상 다리높이 조절장치에 관한 것으로서, 더욱 상세하게는 상부다리가 하부다리에 끼워져 단계적으로 조절되게 하기 위하여 상기 상부다리에 구비되는 고리형의 슬리브가 좌우측으로 움직이게 함으로써, 슬리브의 핀이 다리의 높이조절구멍에 선택적으로 끼워져 높낮이가 조절되고, 높이조절 후 슬리브는 나사체결식 덮개에 씌워져 견고하게 고정되도록 한 책걸상 다리높이 조절장치에 관한 것이다.The present invention relates to an apparatus for adjusting the height of the leg of a book chair, and more particularly, in order to adjust the upper leg in a stepwise manner by being inserted into the lower leg, the annular sleeve provided on the upper leg moves to the left and right, so that the pin of the sleeve is The height adjustment device is selectively inserted into the height adjustment hole of the chair and the height is adjusted, and after the height adjustment, the sleeve is covered with a screw-fastened cover to be firmly fixed.

일반적으로 책상은 상판과 측판이 고정되기 때문에 앉은키에 따라 높이조절이 필요한 경우가 발생된다. 예컨데 학교에서 사용하는 책상의 경우 학생들의 키가 전부 다르기 때문에 고정된 책상을 사용하게 되면 키가 큰 학생과 작은 학생의 경우 표준키에 비하여 사용이 불편한 단점이 있었다.In general, since the top plate and the side plate are fixed to the desk, it is necessary to adjust the height according to the sitting height. For example, in the case of desks used in school, all students' heights are different, so if a fixed desk is used, there is a disadvantage that it is inconvenient to use the tall and small students compared to the standard keys.

이를 감안하여 종래 실용등록 제336861호에는 책상의 높이를 조절할 수 있는 장치가 제안된 바 있다. 이는 책상의 측판 역할을 하는 한쌍의 지주를 이중관으로 제작하여 안테나식으로 출입되도록 하여 책상 상판의 높낮이가 조절되도록 한 것이다. 그러나 이러한 방식의 경우 지주를 이중관으로 만들다보니 재료비가 증가되고 또한 이중관을 고정하기 위하여 다단의 홈과 볼트 및 너트를 구비해야 되므로 조립성이 떨어지는 등의 단점이 있었다.In view of this, a device capable of adjusting the height of a desk has been proposed in conventional utility registration No. 336861. This is to control the height of the desk top plate by making a pair of posts that serve as side plates of the desk as double pipes and allowing them to enter with an antenna type. However, in the case of this method, since the post is made of a double pipe, the material cost is increased, and since multi-stage grooves, bolts, and nuts must be provided to fix the double pipe, there are disadvantages such as poor assembly.

종래 실용등록 제221850호는 책상 측판의 하단에 마련되는 다리에 높이조절볼트를 받침으로 사용한 기술이 제안된 바 있다. 그러나 이러한 높이조절볼트는 볼트의 높이에 한계가 있는 것이므로 책상의 높이조절량이 작아 학교의 책상에는 적합하지 않는 등의 기술적인 한계가 있었다.Conventional Utility Registration No. 221850 has proposed a technique using a height adjustment bolt as a support on a leg provided at the bottom of the side plate of the desk. However, since these height adjustment bolts have a limit on the height of the bolt, there are technical limitations, such as the small height adjustment amount of the desk and not suitable for school desks.

종래 특허 제1862656호는 책상 또는 걸상의 다리를 상부다리와 하부다리로 분리구성하고 상부다리에는 다수의 구멍을 천공하여 고정핀으로 높이가 조절되도록 한 책걸상 높낮이조절장치를 제안한 바 있다.Conventional Patent No. 1862656 has proposed a desk or stool height adjustment device in which the legs of a desk or a stool are divided into upper and lower legs, and a plurality of holes are drilled in the upper legs so that the height is adjusted with a fixing pin.

그러나 종래 특허의 경우 높이를 조절하기 위해 고정핀을 상부다리에서 분리시켜야 되므로 높낮이 조절이 원터치 식으로 이뤄지지 않는 불편함이 있으며, 특히 분리된 고정핀을 분실할 경우 책걸상의 높낮이 조절이 불가능하므로 사용상 매우 불편한 등의 문제점이 있었다. 또한 고정핀이 다리의 한쪽만 체결되므로 체결력이 약하고 반대쪽의 헐거움으로 인하여 상하부다리의 유격이 발생되는 등의 문제점이 있었다.However, in the case of the conventional patent, since the fixing pin must be separated from the upper leg to adjust the height, there is an inconvenience that the height adjustment is not performed in a one-touch manner.In particular, if the separated fixing pin is lost, it is impossible to adjust the height of the chair. There were problems such as uncomfortable. In addition, since the fixing pin is fastened to only one side of the leg, there is a problem in that the fastening force is weak and the gap between the upper and lower legs is generated due to the looseness of the opposite side.

본 발명은 종래의 문제점을 감안하여 개발한 것으로서, 본 발명의 목적은 상부다리가 하부다리에 끼워져 단계적으로 조절되게 하기 위하여 상기 상부다리에 구비되는 고리형의 슬리브가 좌우측으로 움직이게 함으로써, 슬리브의 핀이 다리의 높이조절구멍에 선택적으로 끼워져 높낮이가 조절되고, 높이조절 후 슬리브는 나사체결식 덮개에 씌워져 고정되도록 한 책걸상 다리높이 조절장치를 제공함에 있다.The present invention was developed in consideration of the conventional problems, and an object of the present invention is to move the annular sleeve provided on the upper leg to the left and right so that the upper leg is inserted into the lower leg and adjusted stepwise, the pin of the sleeve It is to provide a device for adjusting the height of the legs of the chair, which is selectively inserted into the height adjustment hole of the leg to adjust the height, and after the height adjustment, the sleeve is covered with a screw-fastened cover to be fixed.

이처럼 구성된 본 발명 한 실시예의 조절장치는 슬리브(30)가 상부다리(10)에서 분리되지 않으므로 분실의 우려가 없는 것으로서, 슬리브(30)의 좌우 이동과정에서 핀(31)이 높낮이조절구멍(12)에 선택적으로 끼워지므로 높이조절이 편리한 이점이 있다. 상기 하부다리(11)의 상단에는 받침부재(20)가 억지끼움식으로 결합되어 빠지지 않는 상태에서 상부다리(10)의 하단으로 덮개(40)와 슬리브(30)가 순차적으로 끼워진다. 이후 상부다리(10)를 하부다리(11)의 상단으로 끼워 넣은 뒤 슬리브(30)의 핀(31)이 상부다리(10)의 어느 한 높이조절구멍(12)으로 들어가도록 한다. 이후 상부다리(10)를 하강시켜 슬리브(30)가 받침부재(20)의 상단에 놓이도록 한다. 이때 슬리브(30) 하단의 밀착부(33)가 받침부재(20) 상단의 경사면(22)을 따라 미끄러지면서 상부다리(10)의 외주면에 밀착된다. 그리고 받침부재(20) 상단의 하부돌기(21)는 슬리브(30)의 여유공간부(32)로 들어가 좌우측으로 움직이지 않고 고정된다.The adjusting device of one embodiment of the present invention configured as described above does not have a risk of loss because the sleeve 30 is not separated from the upper leg 10, and the pin 31 is moved to the left and right in the horizontal movement of the sleeve 30. ), so the height adjustment is convenient. At the upper end of the lower leg 11, the cover 40 and the sleeve 30 are sequentially fitted to the lower end of the upper leg 10 in a state in which the support member 20 is coupled by force fitting and does not come off. After inserting the upper leg 10 to the upper end of the lower leg 11, the pin 31 of the sleeve 30 enters the height adjustment hole 12 of the upper leg 10. After that, the upper leg 10 is lowered so that the sleeve 30 is placed on the upper end of the support member 20. At this time, the contact portion 33 at the lower end of the sleeve 30 slides along the inclined surface 22 at the upper end of the support member 20 and is in close contact with the outer circumferential surface of the upper leg 10. And the lower protrusion 21 at the upper end of the support member 20 enters the clearance space 32 of the sleeve 30 and is fixed without moving left and right.

이후 덮개(40)를 하강시켜 너트부(41)가 볼트부(23)에 체결되도록 하면 슬리브(30)와 받침부재(20)가 동시에 감싸져 조립 완료 된다.Thereafter, when the cover 40 is lowered so that the nut part 41 is fastened to the bolt part 23, the sleeve 30 and the support member 20 are simultaneously wrapped to complete the assembly.

또한 높낮이조절시 위의 과정을 반대로 하면 되는데, 먼저 덮개(40)를 역회전시켜 너트부(41)가 볼트부(23)에서 풀리도록 하여 위로 잡아당기고, 이후 상부다리(10)를 위로 당기면 슬리브(30)가 받침부재(20)에서 벗어난다. 따라서 슬리브(30)를 좌측으로 움직여 여유공간부(32)가 상부다리(10)의 외주면에 밀착되는 과정에서 핀(31)이 높이조절구멍(12)에서 벗어나도록 하고, 이후 슬리브(30)를 상하측으로 움직여서 핀(31)이 다른 높이조절구멍(12)으로 들어가도록 한다. 그리고 상부다리(10)를 하강시키면 슬리브(30)가 받침부재(20)로 들어가는데, 핀(31)을 통하여 슬리브(30)가 상부다리(10)에 걸린 상태이므로 상부다리(10)는 슬리브(30)와 함께 받침부재(20)에 놓인 상태로 높낮이가 조절된다.In addition, when adjusting the height, the above process can be reversed. First, the cover 40 is rotated in reverse so that the nut part 41 is released from the bolt part 23 and pulled upward, and then, when the upper leg 10 is pulled upward, the sleeve (30) deviates from the support member (20). Therefore, by moving the sleeve 30 to the left, the pin 31 is removed from the height adjustment hole 12 in the process of the clearance space 32 being in close contact with the outer circumferential surface of the upper leg 10, and then the sleeve 30 is removed. It moves up and down so that the pin 31 enters the other height adjustment hole 12. And when the upper leg 10 is lowered, the sleeve 30 enters the support member 20. Since the sleeve 30 is caught by the upper leg 10 through the pin 31, the upper leg 10 is a sleeve ( The height is adjusted in a state placed on the support member 20 together with 30).
