본 고안은 가정용 각종 미싱의 모우터에 전원을 공급 또는 전원 공급량을 가변 조절하므로서 미싱의 가동속도를 조절하는 속도 조절기의 압동 장치를 개량하여 작동 방향에 제한을 받지 않고 어느 방향에서던지 구동 시킬 수 있도록 한데 특징을 둔 개량된 고안에 관한 것이다.The present invention improves the pressure regulator of the speed regulator that controls the operating speed of the sewing machine by varying the power supply or the amount of power supply to the motors of various sewing machines for home use, so that it can be driven in any direction without being restricted in the operation direction. It relates to an improved design characterized by one place.
종래의 이러한 종류의 속도 조절기는 제4도와 같이 답압페달 형식으로 구성하여 지랫대상으로 축설된 가동판을 눌러주면 내부의 가변 저항기의 축심을 회전시켜 모우터의 속도가 조절되게 하였던 바 이는 가동판이 편심된 일측의 축심에 지렛대 상으로 축설되어 있어서 가동판의 누르는 방향이 항상 일방향으로 제한되어 있어 작동이 불편하였다.This type of speed regulator in the related art is configured in a stepped pedal type as shown in FIG. 4, and when the movable plate installed as the base object is pressed, the axis of the variable resistor is rotated so that the speed of the motor is controlled. It was built on a lever on one side of the shaft, and the pressing direction of the movable plate was always limited to one direction, which made the operation inconvenient.
본 고안은 이러한 종래의 조절기의 결점에 착안하여 압동판을 반구상으로 형성하여 코일 스프링에 의해 가볍게 상향 탄지되게 한 상태에서 내부에 장착된 가변 저항기를 움직일 수 있도록 하므로서 누르는 방향에 구애 받지 않고 아무 방향에서든지 구동이 자재롭도록 안출한 것으로 이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.The present invention focuses on the shortcomings of the conventional regulator, and the pressure plate is formed in a hemispherical shape so that the variable resistor mounted therein can be moved in a state where it is lightly upwardly touched by the coil spring. In this regard, the drive is designed to be freely described in detail based on the accompanying drawings as follows.
조절기의 통체는 내부에 기판(1)을 내장한 환상체로 구성하여 반 구상의 압동판(3)이 내장된 코일 스프링(4)에 의해 가볍게 상향 탄지 상태로 있도록 하고 기판(1)상에는 고정대(6)에 스프링(9)으로 상향탄지 되는 작동간(7)을 축봉(8)으로 축설하여 이 작동간(7)에 구동치차(10)와 접동판(11)을 착설하여 접동판(11)은 압동판(3)의 상부 내측에 돌설한 돌기(5)에 접지되게 하고 구동치차(10)는 통상의 가변 저항기(13)의 축심에 고정한 구동기어(12)에 맞물리게 하므로서 압동판(13)을 누를시 구동치차(10)가 구동기어(12)를 올려 모우터에 공급되는 전원을 가감 조절할 수 있도록 구성한 것이다.The cylinder of the regulator is composed of an annular body in which the substrate 1 is embedded, so that the semi-spherical pressure plate 3 is lightly lifted up by the coil spring 4 with the built-in coil. ) And the driving gear 10 and the sliding plate 11 are installed on the operating shaft 7 by the shaft bar 8. The pressure plate 13 is grounded to the protrusion 5 protruding from the inside of the pressure plate 3 and the drive gear 10 is engaged with the drive gear 12 fixed to the shaft center of the ordinary variable resistor 13. When pressed, the drive gear 10 is configured to increase or decrease the power supplied to the motor by raising the drive gear 12.
이와같이 된 본 고안은 평상시에는 스프링(4)에 의하여 압동판(3)이 상부로 융기되어 있고 동시에 스프링(9)에 의하여 접동판(11) 역시 돌기(5)에 탄접되어 있는 상태에 있어 가변저항기는 최대 저항치의 지점에서 머물려 있게 된다.The present invention has a variable resistor in the state in which the pressure plate 3 is normally raised by the spring 4 and the sliding plate 11 is also in contact with the protrusion 5 by the spring 9 at the same time. Stays at the point of maximum resistance.
미싱모우터의 구동시 압동판(3)을 아래로 누르면 접동판(11)이 하부로 밀려 내려가면서 구동기어(12)가 구동치차(10)를 돌려주므로 스위치(14)의 접속으로 모우터에 전원이 공급되면서 저항치가 가변되어 압동판(3)을 적게 누를때에는 모우터가 저속 회전이 되고 많이 누르면 고속 회전을 하게 되는 것이다.When the pressing plate 3 is pushed down while the sewing machine is driven, the sliding plate 11 is pushed down, and the driving gear 12 returns the driving gear 10, so that the switch 14 is connected to the motor. When the power is supplied, the resistance is variable, and when the pressure plate 3 is pressed less, the motor rotates at a low speed, and when pressed a lot, the motor rotates at a high speed.
본 고안의 장치에 의하면 압동판이 반구상으로 형성되어 스프링(4)에 상향 탄지되어 있으므로 종래의 조절기와 같이 누르는 방향이 일방향으로 정해져 있는 경우와는 달리 어느 방향에서든지 동일한 작동을 하게 되므로 사용상 매우 편리한 효과를 가지는 것이어서 일반 가정용 미싱, 또는 공업용 미싱에 널리 실용화 할 수있는 것이다.According to the device of the present invention, since the pressure plate is formed in a hemispherical shape and is upwardly supported by the spring 4, unlike the case in which the pressing direction is determined in one direction as in the conventional regulator, the same operation is performed in any direction, which is very convenient in use. It can be widely used in general household sewing machines or industrial sewing machines.
