본 고안은 시력검사기를 재치하는 광학대(光學臺)를 모우터에 의하여 진동없이 조용하게 승강할수 있게한 광학대의 전도(電動) 승강장치에 관한 것이다.The present invention relates to an optical elevating device for allowing an optical stand on which an eye tester is placed to be raised and lowered quietly without vibration by a motor.

종래의 시력검사기의 광학대는 눈의 높이에 맞추어 광학대를 수동으로 상긍하였기 때문에 사용이 불편할 뿐 아니라 능률적으로 시력검사를 정확하게 실시하기 어려운 문제점이 있었다.Since the optical stand of the conventional eye tester manually adjusts the optical stand according to the height of the eye, it is not only inconvenient to use, but also has a problem that it is difficult to efficiently perform the eye test accurately.

본 고안은 이러한 결점을 시정하기 위하여 동체 내부에 광학대가 형성된 승강관을 나사봉에 의하여 승강자재하게 돌설하고 나사봉의 하단부에는 감속모우터를 고무판으로 장착하여 나사봉과 구동축을 유니버샬 조인트로 연결하며 지주의 상단 내부에는 브레이크 밴드를 삽설하여 모우터의 회전진동을 고무판이 모두 흡수하여 광학대가 진동없이 조용이 승강 조절할수 있고 정지위치에서는 브레이크 밴드의 마찰에 의하여 관성회동을 억제하여 원하는 위치에 정확하게 광학대를 승강시키면서 종래의 것에 비하여 보다 능률적이고 편리하게 시력을 정확하게 측정할수 있게 안출한 것으로 이를 도면에 의하여 상세히 설명하면 다음과 같다.In order to correct these defects, the present invention freely elevates the elevating pipe with optical band inside the fuselage by means of a screw rod, and installs a reduction motor with a rubber plate at the lower end of the screw rod to connect the screw rod and the drive shaft with a universal joint. Insert the brake band inside the upper part so that the rubber plate absorbs all the rotational vibrations of the motor, and the optical stand can adjust the quiet movement without vibration.In the stop position, the inertia rotation is suppressed by the friction of the brake band so While elevating to be able to accurately measure the vision more efficiently and conveniently compared to the conventional one as described in detail by the drawings as follows.

동체(1) 하단부에 바퀴(2')가 축설된 다리(2)를 형성하여 수직으로 입설한 광학대에 있어서, 동체(1)내부에 나사봉(3)을 베어링 축수부(4)에 수직으로 축설하여 동체(1)에 삽설된 광학대(5)의 승강관(6)하단 나사부(6')를 나사봉(3)에 승강자재하게 나삽하고 동체(1)의 하단부에 감속모우터(7)를 고무판(8)으로 장착하여 구동축(7')과 나사봉(3)을 유니버샬 조인트(9)로 연결하여 모우터의 회전진동이 나사봉(3)에 전달됨이 없이 회전시킬수 있게하며 동체(1)의 상단내부에 감착된 메탈슬리브(10)에는 승강관(6)의 안내돌조(6")와 기밀성을 유지하는 조절키이(10')를 삽설하고 메탈 슬리브(10) 상단부에는고무재질의 브레이크 밴드(11)를 조절나사(11')와 스프링(11")에 승강관(6)을 알맞는 강도로 협착할수 있게 장착하여 회전관성으로 회동되는 것을 억제할수 있게하여 동체(1)의 내부 상하에는 리밋트 스위치(S1)(S2)를 각각 장착하고 동체(1)의 상단외부에 전원스위치(SW)를 장착하여서된 것이다.In the optical stand vertically formed by forming a leg 2 on which the wheel 2 'is arranged at the lower end of the body 1, the screw rod 3 is perpendicular to the bearing bearing part 4 in the body 1 inside. And screw the lower end of the elevating tube 6 of the optical bench 5 inserted into the body 1 to the elevating screw rod 3 to the lower end of the body 1. 7) by mounting the rubber plate (8) to connect the drive shaft (7 ') and the screw rod (3) by the universal joint (9) to allow the rotational vibration of the motor without being transmitted to the screw rod (3) (1) inserts the guide protrusion (6 ") of the elevating pipe (6) and the adjustment key (10 ') to maintain airtightness in the metal sleeve (10) attached to the upper end of the elevating pipe (6) and the rubber material By mounting the brake band 11 of the adjustment screw 11 'and the spring 11 "so that the elevating pipe 6 can be squeezed with a suitable strength so as to suppress rotation by rotational inertia. Limit switches (S 1 ) (S 2 ) are respectively mounted on the upper and lower sides of the inner shell), and a power switch (SW) is mounted outside the upper end of the body (1).

도면중 P는 전원 플럭이다.P in the figure is a power supply plug.

이와같이 된 본 고안은 광학대(5) 위에 검안기를 설치하여 사용하는 반 검안자의 눈의 높이에 맞추어 광학대(5)를 조절하려면 플럭(P)을 전원 콘센트에 삽착하고 스위치(SW)를 일측으로 재치면 감속모우터(7)가 일측으로 회동하여 나사봉(3)을 일측으로 회동시키어 승강관(6)이 나사봉(3)에 의하여 상승하고 스위치(SW)를 타측으로 재치면 감속모우터(7)가 타측으로 회동하면서 나사봉(3)을 타측으로 회전하여 승강관(6)은 하강시키어 광학대(5)의 높이가 원하는 위치에 도달했을때 스위치(SW)를 개방시키면 브레이크 밴드(11)에 협착된 승강관(6)의 정지로 광학대(5)가 정위치에서 정지하게 되는 것으로 모우터를 고무판(8)으로 장착하고 나사봉(3)과 구동축(7') 사이를 유니버샬 조인트(9)로 연결하였기 때문에 모우터의 회전진동이 고무판(8)에 흡수된채 나사봉(3)에는 회전력만이 전달되어서 승강관(6)이 조용하게 승강되며 또한 메탈슬리브(10)에 삽설된 조절키이(10')에 의하여 승강관(6)의 안내돌조(6")와 기밀성을 유지하게 되어 승강관이 승강할때 축심에서 좌우로 유동되는 일이 없고 동체 상부에 브레이크 밴드를 내설하여 항상 승강관을 탄성을 가지고 협지하게 하였기 때문에 나사봉의 회전에 의하여 승강관이 승강할때 어느정도 접찰저항을 가지게되어 스위치를 개방하여 모우터의 회전력이 없게 되면 승강관도 즉시 그 자리에서 정지하게 되므로 스위치 조작으로 광학대를 용이하게 승강 조절하면서 보다 능률적으로 편리하고 정확하게 검안을 할수 있는 효과가 있다.According to the present invention, the plug (P) is inserted into the power outlet and the switch (SW) is set to one side in order to adjust the optical bench (5) to the height of the eyes of the half optometrist using the optometry on the bench (5). When the deceleration motor 7 is rotated to one side and the screw rod 3 is rotated to one side, the elevating pipe 6 is lifted by the screw rod 3 and the switch SW is placed to the other side. (7) is rotated to the other side by rotating the screw rod (3) to the other side to lower the elevating pipe (6) to open the switch (SW) when the height of the optical bench (5) reaches the desired position, the brake band ( 11) The optical stand 5 stops at the correct position by stopping the elevating pipe 6 squeezed in 11). The motor is mounted with a rubber plate 8, and the screw rod 3 and the drive shaft 7 'are universal. Since it is connected by the joint (9), the rotating vibration of the motor is absorbed by the rubber plate (8) and the screw rod (3) Only the rotational force is transmitted so that the elevating pipe 6 is quietly elevated and also maintains airtightness with the guide protrusion 6 "of the elevating pipe 6 by the adjustment key 10 'inserted in the metal sleeve 10. When steel pipes are raised and lowered, they do not flow from left to right at the center of the shaft, and the brake band is built up in the upper part of the fuselage to always hold the elevating pipe with elasticity. If the motor has no rotational force by opening the switch, the elevator tube also stops at the spot immediately, so it is possible to easily and accurately adjust the optical bench by operating the switch, making it more convenient and accurate for optometry.
