Claims

[Scope of utility model registration request]

A bed machine frame is provided with a cutout opening, an outer hook is disposed within the opening and rotatably supported, and an inner hook is fitted into the outer hook to be stationary and rotatably stores a bobbin thread bobbin. In a horizontal hook device for a sewing machine equipped with a horizontal full-rotation hook mechanism, the movement of the inner hook of the hook mechanism in the thrust direction is regulated downwardly by the race surface of the outer hook, and upwardly by the race surface of the outer hook. One part is regulated by the back surface of the throat plate fixed to the opening, and the other upper part is regulated by the back surface of the square plate slidably supported on the bed machine frame to restrict the minimum gap through which the needle thread can pass. While holding and regulating, the closed state of the square plate is maintained, and the open state of the square plate is controlled upward in the thrust direction of the inner pot, and at the first position where only the bobbin in the inner pot can be taken out. An opening regulating member is provided to temporarily stop the square plate, and the square plate is moved over the opening regulating member to a second position where the upper restriction in the thrust direction of the inner pot is released and the inner pot can be taken out. An inner hook holding device for a horizontal hook of a sewing machine, characterized in that a stopper is provided on the square plate.
