Abstract

선풍기 좌우 각도를 조절하는 장치로써 선풍기 넥크와 옆에 같이 붙어있는 고정핀(이것은 후미에 크랭크 축과 연결되어 있다.)을 이송나사에 의한 거리 조정으로 말미암아 회전 각도에 변화가 생긴다. 이를 구동하는 힘은 와이어 케이블과 연결되어 있는 피니언을 래크의 물리적인 수평 운동으로 발생한다. 이에 수평 운동하는 래크를 계기판 표면을 장치한다.It is a device that adjusts the fan's left and right angles, and the rotation angle is changed by adjusting the distance of the fan neck and the fixing pin (which is connected to the crank shaft at the rear) by the feed screw. The force driving this is generated by the rack's physical horizontal movement through the pinion connected to the wire cable. The rack which moves horizontally is equipped with the instrument panel surface.

Description

선풍기 좌우 풍향 각도 조절 장치{.}Fan left and right wind direction angle adjustment device {.}

본 고안은 선풍기 좌우의 각도를 임의로 조절하는 장치이다.The present invention is a device for arbitrarily adjusting the left and right angles of the fan.

선풍기 각도가 좌우 90°정도를 회전하는 것이 통상적인데 이것을 간편한 제어로 90°에서 30°정도까지 마음대로 좌우의 폭이 똑같게 각이 조절된다. 선풍기 넥크(2) 부분 옆에 고정핀(1)이 후미회전크랭크(4)와 붙어 있다.It is common that the fan angle rotates about 90 ° to the left and right, and this is easily controlled by 90 ° to 30 ° by the simple control. A fixing pin 1 is attached to the rear rotation crank 4 next to the fan neck 2 portion.

이 고정핀(1) 이송나사(6)에 의해 중심으로부터 멀어지게 한 결과 회전폭이 감소된다. 반대로 가까이하면 원래의 회전각이 나온다. 도 4에서와 같이 크랭크의 회전운동을 고정핀(1)이 이동함으로써 상쇄시킨 결과이다. 이송나사(6)의 와이어는 조절장치밑의 피니언(3)과 맞물려 회전운동에 의해 고정핀(1)의 직선운동이 가능하다. 조절장치에는 래크와 피니언(3)을 사용하여 래크가 계기가 되어 90°, 70°, 50°, 30°를 콘트롤한다. 30°이하의 각도는 고정상태와 별반 차이가 없으므로 생략함과 더 이상의 각도를 줄이려고 하면 고정핀(1)의 이동 거리(ℓ)가 멀어져 선풍기 회전망에 걸릴 위험이 있다.The rotational width is reduced as a result of moving away from the center by the fixing pin 1 and the transfer screw 6. On the contrary, close to the original angle of rotation. As shown in Figure 4 is the result of offsetting the rotational movement of the crank by the fixing pin (1). The wire of the feed screw (6) is engaged with the pinion (3) under the adjusting device to enable the linear motion of the fixing pin (1) by the rotational movement. The rack uses a rack and pinion (3) for the adjustment, and the rack is used to control 90 °, 70 °, 50 ° and 30 °. Since the angle of 30 ° or less is not significantly different from the fixed state, the omission and reduction of the angle further increase the moving distance (ℓ) of the fixing pin 1, which may be caught by the fan rotating network.

도면 2는 고무줄(5)의 신축성을 이용하여 선풍기의 키를 조정할 때 와이어케이블의 길이를 보정하는 그림이다.2 is a drawing for correcting the length of the wire cable when adjusting the height of the fan by using the elasticity of the rubber band (5).

선풍기의 각도조절에 의한 바람의 효율적 이용.Efficient use of wind by adjusting angle of fan.

고정핀의 이동에 있어 이송나사의 회전 운동이 고정핀의 직선운동을 발생시킨다. 고정핀의 거리가 멀수록 회전하는 크랭크의 상ㆍ하사점의 거리차이가 발생하는데 이것이 넥크의 회전력을 결정한다.In the movement of the fixing pin, the rotational movement of the feed screw generates the linear movement of the fixing pin. The farther the fixing pin is, the greater the distance between the top and bottom dead center of the rotating crank, which determines the rotational force of the neck.

고정핀이 길어지므로 넥크의 회전반경이 좁아진다.The longer the fixing pin, the narrower the radius of rotation of the neck.

종래의 기술은 후미의 크랭크 지름을 조정하는 장치등이 많으나 이것은 아주 복잡한 구조다.Conventional techniques have many devices for adjusting the rear crank diameter, but this is a very complicated structure.

회전의 폭은 고정핀의 길이에 비례한다. 길이 조정을 콘트롤하는 피니언의 회전수를 래크의 직선운동이 커야 조정이 가능하다.The width of the rotation is proportional to the length of the fixing pin. The number of rotations of the pinion that controls the length adjustment can be adjusted only when the linear motion of the rack is large.
