  For this reason, the trigger horizontal shaft 19 is rotated around the central axis of the horizontal shaft 19a by the restoring force of the pair of left and right trigger springs 22a and 22b, so that the trigger stopper 20 is rotated. As a result, the locked state between the trigger stopper 20 and the locking step portion 13c of the rotor 13 is released.

  As a result, the rotor 13 is rotated around the central axis of the rotating shaft 12a by the spring restoring force of the rotor biasing spring 14, and the locking step portion 13c strikes the stopper 18 as shown in FIGS. And stop. As a result, the rotor 13 rotates approximately 90 ° and stops at the locked position.

  Since the rotation of the rotor 13 is transmitted to the knob 12 by the rotating shaft 12a, the knob 12 rotates approximately 90 ° on the fitting hole 4b of the fastener 4 as shown in FIG. Move. For this reason, since the knob 12 faces in the vertical direction with respect to the lateral fitting hole 4b of the fastener 4, the locked state in which the fastener 4 cannot be removed from the lock body 3 is obtained.

  Then, when releasing this locked state, that is, when unlocking, the vertical knob 12 is picked with a finger and rotated manually in the direction opposite to the locking direction. As shown in FIG. It is set in the horizontal direction and in the same direction as the horizontal fitting hole 4b of the fastener 4. As a result, the fastener 4 can be removed from the lock body 3.

  Then, as shown in FIGS. 6 to 7 again, the rotor 13 rotates about the central axis of the rotating shaft 12a, and the locking step portion 13c of the rotor 13 is locked to the locking tip portion 20a of the trigger stopper 20. The claw tip portions 21a1, 21b1 of the pair of left and right trigger claws 21a, 21b protrude upward from the pressing surface 5a from the claw insertion holes 7a, 7b.

  Therefore, according to this lock 1, it is possible to lock simply and quickly by simply pressing the fastener 4 onto the pressing surface 5 a of the lock body 3. In addition, at this time, since the fastener 4 is also attracted and fixed by the magnet 16, the reliability of locking can be improved. Also, the locked knob 12 can be easily and reliably unlocked by picking it with a finger and simply rotating it to the unlocking position by human power.

  And according to this lock 1, since the trigger claws 21a, 21b are on the left and right, as shown in FIG. 12, the fastener 4 pressed against the pressing surface 5a of the lock body 3 should be in the width direction ( Even if it is slightly inclined in the left-right direction), it can be locked if one of the pair of left and right trigger claws 21a, 21b is pressed by the fastener 4.

  Further, according to the lock 1, the pair of left and right trigger claws 21a and 21b for releasing the locking state between the trigger stopper 20 and the rotor 13 are arranged substantially parallel to the pressing surface 5a and arranged in the horizontal direction. Since the trigger horizontal shaft 19 is driven by turning around the central axis, the thickness of the machine room 10 can be reduced. As a result, it is possible to reduce the thickness of the lock body 3 and improve the aesthetic appearance.

  Further, the bottom plate 11a of the back plate 11 is provided with an insertion hole boss portion 11j protruding inside the bottom plate 11a, and the washer 23 is rotated within the recess of the insertion hole boss portion 11j. The lower legs 11f and 11g can be deleted to further reduce the thickness of the lock body 3.

  In the above embodiment, the case has been described in which the upper fitting hole 4b in FIGS. 1 and 2 of the fastener 4 is fitted to the knob 12 of the lock body 3 and locked, but the present invention is limited to this. Instead, the fastener 4 may be locked or unlocked by fitting it into the lower fitting hole 4c in FIG. 1 or FIG. Moreover, although the said embodiment demonstrated the case where a school bag was used as a bag, this invention is not limited to this, It can apply to the bag which has a bag main body and a cover member. Further, the fastener 4 may be formed of resin instead of metal such as iron. In this case, the magnet 16 becomes unnecessary.

  As mentioned above, although several embodiment of this invention was described, these embodiment is shown as an example and is not intending limiting the range of this invention. These novel embodiments can be implemented in various other forms, and various omissions, substitutions, and changes can be made without departing from the scope of the present invention.
