This is because the conventional device connects the releasing member to the actuator fixed to the machine head machine frame and fixes the moving position of the releasing member. Therefore, in a configuration in which the needle bar base reciprocates in the left-right direction like a zigzag sewing machine, the release member cannot be moved to the vertical movement position of the engagement / disengagement mechanism depending on the position of the needle bar base, and the engagement / disengagement mechanism is connected. Cannot be released to release the needle bar.

付けたことを特徴とする。A needle bar releasing device for a zigzag sewing machine according to the present invention is provided with an engaging / disengaging mechanism for releasing the grip in a grip portion of a vertically moving arm that grips the needle bar and moves up and down. In a needle bar release device for releasing the connection of the engagement / disengagement mechanism by moving the release member to an up / down position of the engagement / disengagement mechanism by an actuator, the needle bar is supported so as to be vertically movable. In addition, the release member and the actuator are attached to a needle bar base that reciprocates in the left-right direction.

When the engagement / disengagement mechanism contacts the release member, the connection of the engagement / disengagement mechanism is released. Both the actuator and the release member are attached to the needle bar base, and move in the left-right direction integrally with the engagement / disengagement mechanism. Therefore, no matter where the needle bar moves due to the reciprocating motion of the needle bar base in the left-right direction, the release member is moved to the vertical movement position of the engagement / disengagement mechanism, and the needle bar is released.

As a result of the release lever 25 swinging in this way, the inclined surface 65 at the lower end of the release lever 25 moves to the vertical movement position of the overhanging portion 55 of the engaging claw base 21. Therefore, when the needle bar 11 that has been vertically moved up to now rises next time, the inclined surface 6 of the release lever 25
The overhanging portion 55 rides on 5 and the claw portion 53 of the engaging claw 37 is disengaged from the engaging groove 29 of the slider 19. Then, since the engaging claw base 21 is pulled upward by the tension spring 31, the needle bar 11 is held at the upper limit position where it abuts the needle bar stopper 33. When the needle bar crank 7 moves up and down, the slider 19 slides up and down on the needle bar 11 and does not move the needle bar 11 up and down.

Since the release lever 25 is pulled back by the tension spring 69, the inclined surface 65 of the release lever 25 is disengaged from below the overhanging portion 55 of the engaging claw 37. Then, the slider 19 moves up next, and the engaging groove 29 of the slider 19 moves into the claw portion 53 of the engaging claw 37.
When reaching the height of, the claw portion 53 engages with the engagement groove 29. In this way, the slider 19 and the engaging claw base 21 are connected again to be in the state of FIG. 1, and thereafter, the needle bar 11 is moved up and down by the vertical movement of the needle bar crank 7.
