Abstract

A sewing machine includes a sewing needle moved up and down and having an eye, a threading hook passed through the eye of the needle, an urging member for urging the threading hook upward, an actuating member for moving the threading hook downward against an urging force of the urging member so that the threading hook is passed through the needle eye, a transmitting member moved between a transmission position where an operation of the actuating member is transmitted to the threading hook and a non-transmission position where an operation of the actuating member is not transmitted to the threading hook, a thread holding member for holding a thread, a moving mechanism for moving the thread holding member near to a position where the thread held by the thread holding member is located near the threading hook having been passed through the eye of the needle, and an abutting member abutting the transmitting member when the thread holding member has been moved to the position of the thread to move the transmitting member from the transmission position to the non-transmission position.

Description

technical field [0001] The present invention relates generally to sewing machines, and more particularly to sewing machines provided with a threading hook for passing thread through the eye of the needle. Background technique [0002] A conventional sewing machine includes a threading device, which includes a threading hook that can be close to and away from the eye of the needle, a threading bar for supporting the hook, a threading lever connected to the threading bar, a threading lever for holding the sewing thread in the The retaining member in two positions and a movement mechanism for moving the retaining member about the eye of the needle. The threading device is arranged above the moving range of the needle to prevent it from colliding with the needle. In the above-mentioned threading device, the threading lever is vertically operated, and like this, the threading rod can move downwards together with it. When the threading lever moved down to the lowermost position,...
