도면에 표시하고 본문에 상술한 바와 같이 재봉기의 기틀에 세로방향으로 이동가능하게 장착되고, 하단에 노루발이 장착된 노루발대와, 상기 노루발에 대향해서 위치하여 재봉기의 바늘판상면으로부터 출몰해서 이송운동을 하는 이송톱날과, 상기 노루발대에 아래쪽으로의 부세력을 부여하는 스프링수단을 구비하고, 그 스프링수단의 부세력의 작용하에 있어서 이송톱날이 노루발과 협동해서 그들 사이에 위치하는 가공천을 이송하는 재봉기에 있어서, 상기 스프링수단으로서 정하중스프링을 사용하는 동시에, 그 정하중스프링의 대충 일정한 스프링힘의 작용에 의해 상기 노루발대에 부여되는 아래쪽으로의 부세력을 변경하는 조절수단을 설치하고, 가공천의 두께의 변화에도 불구하고 항상 조절된 일정한 압압력으로 노루발이 가공천을 압압하도록 한 것을 특징으로 하는 재봉기를 위한 천압압장치.As shown in the drawing and described above in the main body, the presser foot stand is mounted to be movable in the longitudinal direction on the sewing machine's base, and the presser foot is mounted at the lower end thereof, and is positioned to face the presser foot, and emerges from the needle plate upper surface of the sewing machine for the transfer movement. And a spring means for imparting a downward force on the presser foot to the presser foot, and the conveying saw blade cooperates with the presser foot to convey the work cloth positioned between them under the action of the spring force of the spring means. In the sewing machine, a constant load spring is used as the spring means, and at the same time, an adjustment means is provided for changing the downward force applied to the presser foot by the action of a substantially constant spring force of the static load spring. In spite of the change in thickness, the presser foot presses the fabric with constant pressure Cloth pressing device for a sewing machine, characterized in that a. 상기 조절수단이 정하중스프링과 노루발대에 연결된 링크와, 그 링크의 요동지점(搖動支點)을 구성하는 이동가능한 축핀과, 그 축핀을 이동시킴으로써 상기 요동지점을 조절하기 위한 조작부재로 이루어지는 특허청구의 범위 1기재의 재봉기를 위한 천압압장치.The adjusting means includes a link connected to a static load spring and a presser foot, a movable shaft pin constituting a swing point of the link, and an operation member for adjusting the swing point by moving the shaft pin. Overpressure device for sewing machine of range 1. 상기 정하중스프링은 중간부가 밀착되어 감기고 양단이 각기 재봉기기틀과 상기 링크에 연결된 만곡 코일스프링으로 이루어진 특허청구의 범위 2기재의 재봉기를 위한 천압압장치.The static load spring is a pressurizing device for a sewing machine according to claim 2, wherein the middle part is in close contact with the winding and both ends are respectively composed of a sewing machine frame and a curved coil spring connected to the link. ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.※ Note: The disclosure is based on the initial application.
