본 고안은 의자의 양다리를 상,하부로 분리시켜 필요에 따라 의자의 높이를 조정할 수 있는 양다리조정대의 지지강도를 보강시킨 의자의 높이조정장치에 관한 것이다.The present invention relates to a chair height adjustment device that reinforces the support strength of both legs adjustor that can adjust the height of the chair as necessary by separating the legs of the chair to the upper and lower.
종래에도 의자의 양다리를 상,하부대로 분리시켜 상,하부대의 사이간격조절로 의자의 높이를 조정하여 볼트로서 체결시키는 높이조정장치가 있었으나 분리된 양다리가 의자에 앉은 사람의 체중을 지탱하여야 하고 이 분리된 상,하부다리대의 가운데 종선에 상하로 다수의 볼트공을 천공시켜 두 개의 볼트로서 체결시켰으므로 양다리의 강도가 약화될뿐만 아니라 볼트체결부분이 취약부가 되어 오래 사용하지 못하는 결점이 있었다.Conventionally, there was a height adjusting device that separates both legs of the chair into upper and lower parts and adjusts the height of the chair by tightening the bolts by adjusting the height between the upper and lower parts, but the separated legs must support the weight of the person sitting on the chair. Since a plurality of bolt holes were punched up and down on the vertical line in the middle of the separated upper and lower legs, as two bolts were weakened, the strength of both legs was weakened, and the bolt connection part was vulnerable so that it could not be used for a long time.
본 고안에서는 이와같은 결점을 보완하고져 상,하부로 분리된 좌판하부의 대판형 양조정대의 강도를 보강하고져 대판형의 양조정대에는 양측가장자리단의 내측으로 직각이 되게 굴곡시키고 가운데 종선을 중심으로 대판 양쪽면을 내측으로 돌출되게 두줄의 지지돌조를 형성시키고 이 두줄의 지지돌조사이의 내부면에는형 지지보강대를 부착시켜서 대판형 양조정대의 지지강도를 최대한으로 보강시키고 볼트가 체결되는 볼트공부분의 강도를 보강하고져 대판형 양조정대에는형 지지보강대가 부착된 이중판의 가운데종선에 상하로 다수의 볼트공을 천공시키고 중공 직사각형의 양다리에는 상부단을 압축시켜 양장측면이 접합되게 적층판으로 형성시키고 이 적층판의 양측단을 내측으로 직각이 되게 굴곡시킨 상부접속대의 가운데 종선에 상하로 두 개의 볼트공을 천공시켰으므로 볼트공이 천공된 부분들이 모두 이중판으로 전체형상도형으로 지지강도를 보강시켜서 취약점을 보완시킨 것으로 도면에 의거 상세히 설명하면 다음과 같다.The present invention compensates for these shortcomings and reinforces the strength of the large plate-shaped adjustment bar on the lower part of the lower plate separated into upper and lower parts. Two rows of support protrusions are formed to protrude both sides inward, By attaching the type support reinforcing rod, the supporting strength of the large type double adjusting rod is reinforced to the maximum, and the strength of the bolt hole where the bolt is fastened is reinforced. Drill multiple bolt holes up and down in the middle vertical line of the double plate with type support reinforcement, compress the upper end to the hollow rectangular legs, and form the laminated plate so that both sides are joined together. Since two bolt holes were drilled up and down on the vertical line in the middle of the upper connecting rod, all the bored parts of the bolt holes were double plates. The weakness is supplemented by reinforcing the support strength in the form.
좌판(10)하부에 양측가장자리단(13)이 내측으로 직각이 되게 굴곡되고 가운데 종선을 중심으로 대판양쪽면이 내측으로 두줄의 지지돌조(14)가 돌출된 양조정대(11)와 다리받침대(20)상부의 양다리대(21)를 가운데 종선으로 각각 천공된 수개의 볼트공을 상하로 높이를 조정하여 볼트(1)로서 체결하는 공지의 다리높이조정장치에 있어서 양조정대(11)내측의 두줄 지지돌조의 사이내부면에 가운데종선의 상하볼트공을 상호 일치되게 천공시킨형 지지보강대(15)를 부착시켜서 중공직사각형 양다리대(21)의 상부단을 양장측면이 접합되게 적층판으로 압축시켜 양측단(24)을 내측으로 직각이 되게 굴곡시킨 상부접속대(23)로서 높이를 조정하여 볼트공에 볼트(1)로서 체결시켜서 된 것이다.Both side edges 13 are bent at right angles to the bottom of the seat plate 10, and both sides of the large plate are protruded inwards with two support protrusions 14 protruding inwards from the center of the vertical line. 20) In the well-known leg height adjusting device for fastening the upper and lower legs 21 in the middle of several bolt holes, each of which is drilled vertically, to be fastened as the bolt 1, two rows of the inner side of the adjusting bar 11. The upper and lower bolt balls of the middle vertical line were drilled in the inner surface of the supporting protrusions By attaching the type support reinforcing bar 15, the upper end of the hollow rectangular legged leg 21 is compressed into a laminated plate so that both sides are joined to each other, and the upper end 23 is bent so that both ends 24 are bent at right angles inward. By tightening the bolt to the bolt hole as the bolt (1).
이와같은 구조로 된 본 고안은 상,하부로 분리되어 볼트로서 체결되는 좌판(10)하부의 대판형 양조정대(11)와 다리받침대(20)상부의 중공직사각형 양다리대(21)의 전체 강도와 볼트공 부분의 강도를 보완하고져 대판형의 양조정대(11)에는 양측 가장자리단(13)을 내측 직각이 되게 굴고시키고 가운데종선의 상하 볼트공(12)을 중심으로 대판 양쪽면을 내측으로 돌출되게 두줄의 지지돌조(14)를 형성시키고 이 두줄의 지지돌조의 사이내부면에는형 지지보강대(15)를 부착시켜서 대판형의 양조정대의 지지강도를 최대한으로 보강시키고 볼트가 체결되는 볼트공 부분의 강도를 보강하고져 대판형 양조정대(11)에는 두줄의 지지돌조(14)의 사이내부면에 부착된형 지지보강대(15)의 이중판의 가운데 종선에 상하로 다수의 볼트공(12)를 천공시키고 중공직사각형 양다리대(21)에는 상부단을 양장측면이 접합되게 적층판으로 압축시켜 양측단(24)을 내측으로 직각이 되게 굴곡시킨 상부접속대(23)의 가운데종선에 상하로 두 개의 볼트공(22)을 천공시켰으므로 볼트공이 천공된 부분들이 모두 이중판으로 전체형상도형으로 지지강도를 보강시켜서 볼트공 부분의 취약점을 보완시킨 것이다.The present invention having such a structure is divided into upper and lower, and the overall strength of the large plate-shaped adjuster 11 of the lower part of the seat plate 10 and the hollow rectangular legs 21 of the upper leg rest 20 which are fastened as bolts. Compensating the strength of the bolt hole portion to roll the both ends of the edge 13 to the inner right angle to the large plate-shaped adjuster 11 and to protrude both sides of the base plate in the center of the upper and lower bolt holes 12 of the middle longitudinal line Two rows of support protrusions 14 are formed and the inner surface of the two support protrusions By attaching the type support reinforcing bar (15) to reinforce the support strength of the large-type double adjustment bar to the maximum, and to reinforce the strength of the bolt hole portion to which the bolt is fastened, the large support bar (11) of the two support protrusions (14) Attached to the inner surface Perforations of a plurality of bolt holes 12 up and down in the middle vertical line of the double plate of the type support reinforcement 15, and the hollow rectangular legs (21) by compressing the upper end with a laminated plate so that both sides are joined to both sides (24) Since two bolt holes 22 were drilled up and down in the middle vertical line of the upper connecting section 23, which was bent at right angles to the inside, all the holes where the bolt holes were drilled were doubled in overall shape. By reinforcing the support strength with the type, the weakness of the bolt hole part is compensated.
