Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention engages a lock body disguised in a case with a lock plate stacked on it using several magnets, and locks the magnets with a predetermined key. 〇 Concerning an electronic lock that allows the lock plate to rotate when unlocked (Conventional technology and its problems) A part of the magnet is fitted into the recess of the overlapping lock plate to stop the lock plate from rotating. A magnet is embedded in the key so that magnetic poles of the same sex face each other at the same position as the lock body, and when this key is stacked on the chest plate, all the magnets in the lock body are repelled and come out of the recess in the lock plate, causing the magnet to dislodge. When the lock is released, the lock plate can be rotated.In addition, the present inventor has developed a suction-type electronic lock (Special Public Shodan No. 1983CII) that unlocks by suctioning the magnet on the lock body. For electronic locks, radial grooves are cut in both the lock body and the lock plate, and a relief groove is provided in either of the radial grooves, and a part of the magnet inserted into the radial groove in the lock body is inserted into the radial groove in the lock plate. The rotation of the lock plate is stopped by the key, and all the magnets of the lock body are attracted to the joint between the radial groove and the escape groove, so that the lock plate can be rotated.

However, with a repulsion type electronic lock, when you move a small magnet on the lock plate, the magnet inside the lock body will repel it, and with a suction type electronic lock, when you move a small magnet on the lock plate, it will be repelled by the magnet inside the lock body. Since the electronic lock is attracted, the position of the magnet inside the lock body can be detected from the outside, and as a result, there is a risk that the electronic lock may be illegally unlocked. An object of the present invention is to provide an electronic lock that combines a suction-type electronic lock and a repulsion-type electronic lock to make unauthorized unlocking impossible.

↓ [Meaning is also a solution] The present invention stacks a lock plate on a lock body fixed to a cylindrical case, and inserts the 8 rods into the shaft hole of the lock body, and connects the front side of the lock body and the back side of the lock plate. Cut the radial grooves, create an arc-shaped escape groove in either of the radial grooves, fit a part of the magnet inserted into the radial groove of the lock body into the radial groove of the lock plate, and drill it in the front of the lock body. Insert a magnet and a spring into the blind hole, and attach a part of this magnet to the 11 lock plate On! ]Toko”“8
・The magnet in the lock plate 1"-116~- attracts the magnet in the radial groove and transfers it to the connection part with the relief groove, and another magnet in the key repels the magnet in the blind hole and pulls it out of the recess in the lock plate. , W is formed so that the lock plate can be rotated by releasing the engagement of the magnet by attraction and repulsion.

Next, a fairly deep blind hole of 20° was drilled in the front part of the tatsuku body 4 on the diameter line in the left and right direction perpendicular to the radial groove 15.15.
Two shallow recesses 21, 21 are also bored on the back side of the lock plate 10 on the diameter line perpendicular to the radial grooves 16, 16, and a pair of short and small magnets 22 and spring fins are installed in the blind holes 20, 20 of the lock body. press the magnet 22 with the spring and push a part of it into the recess 2 of the lock plate.
1.21, and two sets of repulsion type electronic locks 1.1 having such a configuration are assembled into the cylindrical case 1. Lock plate 10
Normally, the rotation is also prevented by the magnets n and 22 that fit into the recesses 21 and 21, and the two magnets 22 and 22 are rebelled by the key magnet (described later) and are inserted into the recess 21 of the lock plate. .21, the lock plate 10 becomes rotatable.

Sae is a circular key having a grip 25'f, which is made in a shape that fits into the lock plate 10 and is housed in its dish-shaped surface, and the protrusion provided on the periphery engages with the notch 27 on the periphery of the lock plate. The use position is restricted and the lock plate 10 is rotated. The key is 4 in the circumferential direction.
A number of short and small magnets 29 are embedded at equal angles, with the upper and lower magnet paths 28 facing the connection between the two radial grooves 16 and relief groove 17 provided on the back of the lock plate, and inside the lock body. magnet 18
and the magnetic poles of the opposite sex are arranged so as to face each other.1. Left and right magnets 2

Different keys are created by changing the position of 21.

One embodiment of the present invention consists of the above-mentioned W configuration, and includes a cylindrical case 1
is inserted into the holder 2, the slope of the protruding tip 7 from the window hole 3 is placed against the outer edge of the holder 2, and when the lock plate 10 is pushed in with the tip of the finger, the pawl piece 6 resists the spring 9 due to the slope of the tip 7. km 5 and when the window hole 3 passes the receiver 2, the claw piece 6 is pushed by the spring 9 and protrudes the tip 7. By hooking this to the rear side of the receiver 2, the cylindrical case 1 is attached to the receiver. It prevents it from coming off the money and locks it. The magnet 18 inserted into the lock body 4
゜18 is located in both the radial groove 15 of the lock body and the radial groove 16 of the lock plate, and the magnets 18 and 18 hit the side wall of the radial groove and cannot move in the same direction, and the magnet of the lock body! ”i
22122 fit into the recesses 21.21 of the lock plate, and these magnets 18.22 prevent the lock plate 100 from rotating to ensure the locked state.

To unlock the lock, engage the protrusion 5 with the notch 26 and place the key on the lock plate lO, then the magnet 18.18 inside the lock body
is attracted to the key's magnetic path, 28, and the 1Ilk line 18'.

As shown at 18', the lock plate 10 becomes rotatable by inserting the magnet 18.18 into the relief groove 17.17. Also, when the key is placed on the lock plate 10, the magnets 22 and 22 in the lock body are repelled by the two magnets 29 and 29 of the key, and the recess 21 in the lock plate is repelled.
Since the extractor comes out from ゜21, the lock plate 10 is attached to this magnet 22.2.
2 is also released and rotation becomes possible. Then, grab the cylindrical case ITt and turn the key 23 about 45 degrees, and the lock plate 10
misses the magnet 18.18 and hits the back end of Tlt17.17.

When the lock plate 10 is rotated, the stepped surface 14 at the end of the core bar pushes down the notch 8 of the claw piece, and the claw tip 7 is recessed into the window hole 3 and aligned with the circumferential surface of the cylindrical case 10. As a result, the claw 7 and the receiver 2 are disengaged, so the cylindrical case 1 is pulled out from the receiver 2 and unlocked. After unlocking, the key is turned in the opposite direction by about 60 degrees to remove it from the lock plate 10, and the magnet 201' stops the rotation of the lock plate 100 and causes the toe 7 to protrude from the cylindrical case.

In this embodiment, an attraction type electronic lock E and a repulsion type electronic lock 7 are combined, and even if a small magnet is attached to the lock plate 10 and moved, the lock plate 10 will be attracted to the position where the magnet is located.
When it reaches a certain point, it receives a repulsive force, so it becomes impossible to detect the position of the magnet inside the lock body from the outside.
Therefore, unauthorized unlocking can be reliably prevented.〇 The above is an explanation of one embodiment of the present invention, and the present invention is not limited to this embodiment, and the design can be changed within the gist of the invention. For example, it is possible to increase or decrease the number of radial grooves 15°16, holes 20 and recesses 2], and
may be provided on the front surface of the lock body 4. Alternatively, instead of the claw piece 6, a latch can be attached directly to the 8 bar 11 of the lock plate, or a cam plate can be attached to this 8 bar to convey the movement of the lock plate to the latch, and the latch moves the metal to the receiver due to the movement of the lock plate. It may also be configured to be hooked.

〔Effect of the invention〕

According to the present invention, since the electronic lock is a combination of attraction type and repulsion type, it is impossible to detect the position of the magnet inside the lock body from the outside, and unauthorized unlocking of the child lock is reliably prevented. effective.
