본 발명은 안두대(安頭臺)를 임의의 경도로 자유롭게 조정할 수 있도록 한 것을 특징으로 하는 치료대의 수동식 경동조정장치(傾動調整裝置)에 관한 것이다.The present invention relates to a manual tilt adjusting device for a treatment table, wherein the ophthalmic zone can be freely adjusted to an arbitrary hardness.
종래 안두대의 수동식 경동조정장치는 원호상안내홈을 구비한 안내통을 등널에서 돌출설치하여 안두대 하부에 설치된 원호상지지축을 상기 안내통에 자유롭게 미끄러져 움직일 수 있도록 끼워넣고, 상기 지지축의 하주면(下周面)에 다수의 래칫이를 새겨만들고, 상기 안내통의 기간부(基幹部)에 상기 래칫이에 맞물리는 래칫클릭을 회전가능하게 설치하고 안두대가 붙어 있는 부분에 돌출설치한 로크장치의 조작핸들에 의해 상기 래칫이로 래칫클릭을 완전히 맞물리게 하여 안두대의 경도를 조정하고 있었다.Conventional ophthalmic manual tilt adjustment device is to install a guide cylinder having an arc guide guide groove protruding from the back panel to insert a circular arc support shaft installed in the lower ophthalmoscope to slide freely to the guide cylinder, the lower of the support shaft A large number of ratchets are engraved on the main surface, and a ratchet click that engages the ratchet teeth is rotatably installed in the main portion of the guide tube and protruded to the portion where the ophthalmic stick is attached. The hardness of the eyeball was adjusted by completely engaging the ratchet click with the ratchet by the operation handle of the locking device.
그러나 종래 장치는 래칫이와 래칫클릭의 맞물림에 의해 조정하므로 단계식 경도조정이 되어 치료에 필요한 경도로 무단계로 조정할 수 없었다.However, the conventional device is adjusted by the engagement of the ratchet and the ratchet click, so stepwise hardness adjustment is not possible to adjust steplessly to the hardness required for treatment.
또한 안두대가 붙어 있는 부분에 로크장치의 조작핸들이 돌출설치 되어 있기 때문에 경도의 조정범위가 제한되어 시술자의 시료시의 동작이나 거처에 방해가 되고, 또한 때로는 상기 조작핸들에 접촉하여 경동기구의 로크가 해제된다고 하는 불량발생의 원인이 되고 있었다.In addition, since the operation handle of the lock device protrudes in the part where the ophthalmic stick is attached, the adjustment range of the hardness is limited, which interferes with the operation or residence of the operator's sample. It was the cause of the failure that lock was released.
본 발명은 상기 과제의 해결을 목적으로 하는 것으로서, 경도의 로크장치를 롤러 웨지식 로크장치(R)로 하여 무단계의 경도조정을 가능하게 하고 그 로크해제장치(F)를 안두대(2)의 이면요부(裏面凹部)(2a)에 매몰하게 하여 시술자에게 방해가 되지 않도록 하고 접촉우려를 없애 경도조정에 지장이 없도록 하였다.SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned problem, and the lock device of hardness is used as a roller wedge type lock device (R) to enable stepless hardness adjustment, and the lock release device (F) of the ophthalmic bag (2). It was buried in the back recess (2a) so as not to disturb the operator and to eliminate contact concerns so as not to interfere with the hardness adjustment.

The fastening plate 3d of the arcuate cover plate 3c is made to collide.
또한 상기 조작버튼(9d)을 놓으면 스프링(8)의 부세력에 의해 다시 로크 롤러(6)는 쐐기고정된다.In addition, when the operation button 9d is released, the lock roller 6 is wedge-locked again by the force of the spring 8.
그때 로크 롤러(6)는 테이퍼면에 압입됨과 동시에 원호상로크해제각봉(10)을 되밀어서 반대로 조작버튼(9b)을 복원시키도록 연동한다.At that time, the lock roller 6 is pushed into the tapered surface and at the same time, it pushes back the arc-shaped unlocking bar 10, and interlocks to restore the operation button 9b.
또한 해제링크(9e)를 원호상지지각통(3)내에 돌출시켜 요동가능하게 하기 위하여 원호상커버판(3c)의 상단에는 창(3e)이 개구되어 있다.In addition, a window 3e is opened at the upper end of the arcuate cover plate 3c so that the release link 9e protrudes in the arcuate support angle cylinder 3 and is swingable.
또한 원호상로크해제각봉(10)은 홈(10a)내에 매설되어 미끄러져 움직이기 때문에 해제링크(9e)의 돌출부(9f)에 쉽게 맞닿도록 그 선단을 L자형으로 구부리고 있다.Further, since the arc-shaped unlocking bar 10 is buried in the groove 10a and slides, the tip is bent in an L shape so as to easily contact the protrusion 9f of the release link 9e.
본 발명 안두대경동조정장치에서는 안두대를 필요한 각도로 자유롭게 조정할 수 있으므로 시술자의 시료에 최적 효과를 갖는다.In the present invention, the ophthalmic tilting adjustment device can be freely adjusted at the required angle to have an optimal effect on the sample of the operator.
또한 본 발명 롤러 웨지식 로크장치에서는 종래와 같은 래칫부의 복잡한 가공이 없어져서 대폭 가공공수를 감소할 수 있다.Further, in the roller wedge type locking device of the present invention, the complicated processing of the ratchet portion as in the prior art can be eliminated, and the number of machining can be greatly reduced.
또한 안두대의 이면요부에 매몰시켜 해제장치대와 조작버튼을 설치하므로 시술자의 시료시에 방해가 되지 않고, 접촉하여 불량상태를 발생시킬 우려도 없으며, 경도의 조정범위도 크게 할 수 있다.In addition, because the buried in the back recess of the ophthalmology is installed to install the release device and the operation button, it does not interfere with the operator's sample, there is no fear of contact and generate a bad state, it is possible to increase the hardness adjustment range.
