Description

[Detailed Description of the Invention] (Field of Industrial Application) The present invention relates to a locking device for bags, cases, etc.

(Prior Art) Conventionally, in a locking device attached to a bag, case, etc., a key is generally used to lock a lock piece in a locked state, as seen in, for example, Japanese Utility Model Application No. 52-17296. ing.

A locking device having such a structure requires a troublesome operation of inserting and rotating a key in order to lock the lock piece and to release the lock. There was also the problem that the lock member was easily rotated and unlocked using a counterfeit key or the like.

(Problems to be solved by the invention) The present invention not only enables ordinary locking and unlocking to be performed by manual operation, but also enables locking of the locked state by a simple manual pressing operation. If you want to unlock a locked bag, you cannot use a counterfeit key, and you cannot tell how to unlock it just by looking at it.
The purpose is to provide locking devices for cases, etc.

(Means for Solving the Problems) In order to achieve the above object, the locking device for bags, cases, etc. of the present invention automatically unlocks when the lid of the bag, case, etc. is released. Attach a locking body that is biased by a spring so that it operates, and
The main body of the case etc. has a locking member for locking the locking body, an operating member for manually releasing the locking member and the locking body, and a locking member that locks the locking member in the locked state. A locking member that locks the locking member, a pressing operation member that slides the locking member to lock the locking member in a notch provided in the locking member, and further includes a pressing member that slides the locking member to lock the locking member. A magnetic member that engages and locks the locking member and releases the lock when the magnetic body is positioned at a predetermined location, and a locking member that releases the lock when the magnetic member releases the lock of the locking member. The lock body is equipped with a spring body that releases the locking of the locking member by the locking member.

(Example) To explain the example shown in the figure, the lid body 1 of the case
A locking body 4 is rotatably attached to the hinge 2 with a tension spring 3 wound around the hinge 2 so as to be biased rearward. That is, when the locking body 4 is released, it automatically rotates backward by the force of the spring 3 and is pulled out from the lock opening 6 of the locking body 5, which will be described later, to perform an unlocking operation. A lock body 5 for locking the lock body 4 is attached to the case body 7. The lock body 5 is provided with a lock hole 6 into which the latch protrusion 8 of the lock body 4 is inserted, and inside the lock body 5 is a plate-shaped latch member 9 whose tip is exposed to approximately the middle of the lock hole 6. It is stored with its end biased by a leaf spring 10.
The latching member 9 is slidable toward the rear end against the pressing force of the leaf spring 10, and can be locked by inserting the latching protrusion 8 of the locking body 4 and when connected to the latching member 9. When the operating member 11 protruding from the upper surface of the lock body 5 is manually moved toward the rear end of the locking member 9 to unlock it, it slides. The latching member 9 is pressed toward the tip by the leaf spring 10 as described above, but since the bent step 12 hits the rib 13, the tip ends at the point where the tip advances to approximately the middle of the lock opening 6. Positioned and stopped. When the latch protrusion 8 of the lock body 4 is inserted into the lock opening 6, the tip of the latch member 9 is pushed by the tip of the latch protrusion 8, moves back once, and then moves forward again to fit into the hole of the latch protrusion 8. It is inserted into the section 14 and latched to become locked. A cutout recess 15 is provided on one side edge of the rear end of the hooking member 9, and the hooking member 9 is locked at a position located above the cutout recess 15 in a direction perpendicular to the longitudinal direction of the hooking member 9. A member 16 and an operating member 17 are located. The locking member 16 has a locking protrusion 18 that can be fitted into the notched recess 15 of the locking member 9 below its base end, and a hole 1 in the center from the tip.
9, and its locking protrusion 18 is connected to the locking member 16.
It passes through a notch hole 20 of the operating member 17 located on the lower surface of. The base end of the operating member 17 is bent upward and extends, and the bent portion 21 abuts the base edge of the locking member 16, and an operating button 22 is fixed to the upper end thereof. Separate leaf springs 23 and 24 abut the distal edges of the locking member 16 and the operating member 17, respectively, and press them in the proximal direction. Now, Figures 4 to 7
As shown in the figure, when the operating member 17 is moved in the distal direction by the operating button 22 against the leaf spring 24, the locking member 16 also engages the leaf spring 23 because its proximal edge is in contact with the operating member 17. The locking protrusion 18 moves toward the distal end against the resistance, and the locking protrusion 18 fits into the notch recess 15 of the locking member 9 and is locked therein. In this locked state, the magnetic member 25 is disposed above the location of the hole 19 of the locking member 16, and the magnetic member 25
5 fits into the hole 19 and fixes the locking member 16 in a locked state to the locking member 9. The operating member 17 is returned to the return position by the pushing force of the leaf spring 24, and is in the state shown in FIGS. 8 and 9. In this state, the locking member 4 is securely locked because the locking member 9 is locked by the locking member 16 and the locking member 16 is also locked by the magnetic member 25. A recess 27 is provided above the magnetic member 25 in which a separate magnetic body 26 can be placed on the upper surface of the lock body.
6 is placed, the magnetic member 25 pops out from the hole 19 of the locking member 16 due to the magnetic force and is inserted into the recess 2.
It is attracted to the bottom surface of 7. As a result, the locking member 1
6 is released and returned to its original position by the force of the leaf spring 23, and at the same time, its locking protrusion 18 is pulled out of the cutout recess 15 of the locking member 9, and the locking member 9 is also released. It becomes movable and the locking body 4 can be unlocked. Here, the magnetic member 25 is held at its periphery by a spring body 28 so as to be able to freely swing in the vertical direction.
A guide wall 19 is provided on the periphery of the magnetic member 25 so that when the magnetic member 25 is locked in the hole 19 of the locking member 16, the position does not shift due to the pushing force of the leaf spring 23. The body 28 passes through a slit 30 in the guide wall 29 and is fixed to the outside. The magnetic member 25 is suspended by a spring body 28 attached to the periphery so as to be able to swing up and down, and the magnetic member 25 moves downward due to the restoring action due to the tensile force of the spring body 28 and is inserted into the hole 19 of the locking member 16. It has a structure that fits in. Note that 31 in the figure is a magnetic member attached to the operating member 17, and is intended to facilitate the insertion of the magnetic member 25 into the hole 19 by suction.
This is not necessarily necessary since it is possible to fit in by restoring with the spring body. Further, although the above-mentioned operating members 11 and 17 are of the horizontal tension type, it is of course possible to use a push button type using a cam or the like.

FIG. 11 shows a different embodiment of the locking mechanism between the locking member 16 and the magnetic member 25. The magnetic member 25 has a hole 32 in the center with one edge tapered. The formed locking piece 33 protrudes and has a spring 34 fixed to its tip, and the locking member 1
The distal end of the locking member 6 also has a tapered shape, and the locking member 16 is biased toward its proximal end by a coil spring 35. Further, although the operating member is not shown, it is integrated with the locking member 16. Now, when the locking member 16 is moved toward the tip against the coil spring 35, the tapered portion at the tip pushes the tapered edge of the hole 32 of the magnetic member 25 and floats against the spring 34, so that the locking member is completely moved. penetrate the hole. When the locking member 16 is moved by a certain length, the locking piece of the magnetic member 25 is pulled by the spring 34 and fits into the hole 36 since the locking member 16 is provided with a hole 36 . The locking member 16 is thereby locked. At this time, although not shown, it is assumed that the locking protrusion of the locking member 16 fits into the notch recess of the locking member to lock the locking member as in the previous embodiment. Next, when the magnetic body 26 is positioned at a predetermined position, the magnetic member 25 is attracted and moves upward, so that the locking member that was locked to the locking piece 33 of the magnetic member is released and is released by the force of the coil spring 35. The locking member returns to its original position, thereby releasing the locking member and allowing the locking body to be unlocked.

(Operations and Effects) Since the present invention is constructed as described above, it can be locked and unlocked by manual operation under normal conditions, and the locked state can also be locked by a simple manual pressing operation. Therefore, the operation is not troublesome and it is easy to use. Once the lock is locked, it cannot be unlocked unless the magnetic body is placed in the specified position, which greatly improves safety, and the structure is simple. Therefore, it has the advantage of being easy to manufacture.
