[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a bag lock.

[0002]

2. Description of the Related Art Conventionally, this kind of bag lock has a drawback that, after operating a knob at the time of unlocking, when the hand is released from the knob, the knob immediately returns to its original position and is closed again.

[0003]

The problem to be solved by the present invention is to solve the above-mentioned conventional drawbacks, and to operate the knob when unlocking,
It is an object of the present invention to provide a bag lock in which a bag can be easily opened by holding a knob at an unlocking position until the bag is opened.

[0004]

The means of the present invention are as follows. On the upper surface of the lock main body fixed to the bag main body, an insertion hole of a locking plate attached to the bag lid is formed, and a concave lock body having an engaging hook is slidably accommodated in the lock main body, and In a bag lock in which a coil spring for engaging an engagement hook with a locking plate acts on a concave lock body, when a bent leaf spring is fixed to the bottom surface of the concave lock body and the concave lock body is operated. A bag lock characterized in that the distal end of the bent leaf spring engages with a notch provided at the lower end of the locking plate to hold the concave lock body in the unlocked position until the lid is opened.

[0005]

[Function] The lid of the bag is closed and the locking plate 3 on the lid side is locked with the lock main body 1.
When the operation knob 6 is operated to slide the concave lock body 5 in a state where the concave lock body 5 is locked to the concave lock body 5, the tip of the bent leaf spring 9 is once pushed down by the locking plate 3. After that, it engages with the notch 3a provided at the lower end of the locking plate 3 (see FIG. 2), so that the concave lock body 5 holds the unlocked position. Then, open the lid of the bag, as shown in FIG.
The lock body 5 comes off the lock main body 1 and the concave lock body 5 returns to the original position (lock position) by the action of the coil spring 11. Then, when the lid of the bag is closed in this state, the bag automatically becomes the state shown in FIG. 1 and the bag is locked.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS In the drawings, reference numeral 1 denotes a lock, which has a handle post 2 and a locking plate 3 attached to the upper surface of a bag on the upper side.
A guide window hole 7 for exposing the operation knob 6 of the concave lock body 5 slidably housed in the lock main body 1 is provided on the front face. On the concave lock body 5, an engaging hook 8 for locking the locking plate 3 is projected inward at an upper end of one side 5a, and is engaged with a notch 3a provided at a lower end of the locking plate 3 on a bottom surface 5b. The bent leaf spring 9 is mounted and supported by the bottom projection 5c. A coil spring 1 is provided between one side 5a of the concave lock body 5 and the partition 10.
1 is contracted so that the upper end bent portion 5e on the other side 5d is in contact with the partition piece 12.

[0007]

According to the present invention, the lock can be securely locked by an extremely simple structure, and when the operation knob is operated at the time of unlocking, the operation knob holds the unlocked position until the bag lid is opened. The operation of opening the bag can be performed extremely easily.
