Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention engages a lock body fitted in a case with a lock plate stacked thereon using several magnets, and locks the magnets with a predetermined key. This invention relates to an electronic lock that can be unlocked to rotate the lock plate.

(Prior art and its problems) -42 Electronic Tsuku hooks the claw piece of the lock body fitted in the case onto the receiver, drills several blind holes in the front of the lock body, and attaches the magnet and spring. A part of the magnet is inserted into the recess of the overlapping lock plate to stop the lock plate from rotating, and a magnet is embedded in the key so that the magnetic poles of the same sex are opposite to each other at the same position as the lock body. When this key is stacked on the lock plate, all the magnets in the lock body are repelled and come out of the recesses in the lock plate, and the magnets are released and the lock plate becomes rotatable. We have developed a suction-type electronic lock (Utility Model Application No. 168657/1989) that unlocks by attracting the magnet on the lock body.This electronic lock has radial grooves cut into either the lock plate or the lock body, and the magnet A part of this magnet is inserted into the annular edge of the lock body or the recess provided in the core rod of the lock plate to stop the lock plate from rotating, and the key magnet is used to remove all the magnets in the radial groove. The lock plate is configured to be rotatable by suctioning the lock plate and pulling it out from the annular edge or recess of the core rod.

However, with repulsion-type electronic locks, if you move a small magnet on the lock plate, it will be repelled by the magnet inside the lock body, and with an attraction-type electronic lock, if you move it with a small magnet attached to the lock plate, it will be attracted to the magnet inside the lock body. Therefore, 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 unlocked illegally. The purpose of the present invention is to provide an electronic lock that combines a suction type electronic lock and a counterattack type electronic lock and makes unauthorized IW ridges impossible. Fit the core into the shaft hole of the lock body, cut a radial groove on either the back of the lock plate or the front of the lock body, insert the magnet and spring, and insert the magnet into the two-part lock body. 1. Insert the magnet into the annular edge or the recess made in the core rod of the lock plate, insert one end of the magnet into the blind hole made in the front of the lock body, and insert part of this magnet into the recess in the plate. When the key is inserted and stacked, the magnet in the key attracts the magnet in the radial groove and pulls it out of the annular edge or recess in the core, and another magnet in the key repels the magnet in the blind hole and pulls it out of the recess in the plate. The structure is such that the lock plate can be rotated by pulling it out from the place and releasing the locking of the magnet by attraction and repulsion.

〔Example〕

In the example shown on the top panel, 11 is a cylindrical case with a bottom (
It is a cylindrical case) that is fitted into an annular receiver 2 fixed to a related member (Δ not shown), and a window hole 3 is provided in the rear corner of the side wall.

A tension spring 9 interposed between this and the end face of the groove causes the wedge-shaped toe 7- to project outward from the window hole 3. The claw piece 6 prevents the removal of the cylindrical case 1 by hooking the claw tip 7 on the receiver 2 and locks it. When the notch 8 on the front (right side) of the claw piece is pushed down, the claw tip 7 engages with the window hole 3. 10 is a dish-shaped lock plate, which is inserted into the entrance (right end) of the cylindrical case 1 and stacked on the front surface of the lock body 4, and the core body 11 is inserted into the shaft of the lock body. Insert into the hole and insert into the annular m13 of the dowel pin 12E core bale driven into the lock body and engage the stepped surface 14 made by cutting off the lower half of the end of the bale without a retainer 7 to the notch 8 of the claw piece. When the lock plate lO is rotated approximately 60 degrees, the stepped surface 14 at the end of the core pushes down the notch 8 of the claw piece, and the claw tip 7 is inserted into the window hole 3.

The two rays a18゜18 extending in the radial direction are equally divided by an angle (
The magnet 20 is cut in the vertical direction) and one set of a short magnet 20 and a spring 21 are inserted, the spring 21 pushes the magnet 20, and a part of the magnet 20 is fitted into the recess 16 cut in the annular edge 15. Two sets of suction type electronic locks Ft and K are assembled into a cylindrical case 1. Normally, the lock plate 10 is prevented from rotating by two magnets 20 that fit into the radial wigs and ia, and the two magnets 20 and 20 are attracted to the key magnet (described later) and are attached to the annular edge opening. The lock plate 10 becomes rotatable when removed from the lock 16.16.

Next, a fairly deep blind hole 22゜n is bored in the front part of the lock body 4 along the diameter line in the left and right direction, and a radial groove 1 is also made in the back side of the lock plate lO.
8. Drill two shallow recesses n and 23 on the diameter line in the left and right direction perpendicular to 18, insert one pair of short and small magnets and springs 5 into the blind holes n and 22 of the lock body, and use the springs 5 to Two sets of repulsion-type electronic locks with such a configuration were obtained by pressing the magnet and fitting a part of it into the recess of the lock plate.1. T! is assembled into the cylindrical case 1. Normally, the lock plate 10 is also prevented from rotating by magnets A and 24 that fit into recesses 23 and 23, and S2 magnets A and 24 are magnets for keys (repelled by J to be described later, and the lock plate is recessed). When removed from jfr23°4, k & 10 can be rotated.

Reference numeral 26 denotes a circular key having a grip 27, which is made in a shape to be stacked on the lock plate 10 and housed in the dish-shaped surface thereof, and a projection provided on the periphery is engaged with a notch 29 on the periphery of the lock plate to determine the use position. control and rotate the plate 10. The key has four short and small magnets 30 and 31 embedded in equal angles in the circumferential direction, and the upper and lower magnets 30 and 30 are laid in the radial direction of the key to form two radial 11
8. Shift it inside the magnet 20.20 housed in the key 20, and place it so that the magnetic poles of the opposite sex are opposite to this magnet 20, and place the left and right magnets 31.31 in the axial direction of the key in the recess n of the lock plate. , 23 and within the lock body magnet 24.24
Different keys are created by arranging the magnetic poles of the same sex to face each other, and changing the orientation of the magnetic poles 24 on the magnet side and the positions of the escape groove 17 and the recess 21.

One embodiment of the present invention has the above configuration, and includes a cylindrical case 1
When the lock plate 10 is inserted into the receiver 2, the slope of the tip 7 protruding from the window hole 3 is placed against the outer edge of the receiver 2, and the lock plate 10 is pushed in with the tip of a finger, the claw piece 6 resists the spring 9 due to the slope of the tip 7. When the window hole 3 passes through the holder 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 holder 2, the cylindrical case is closed. 1 is prevented from being removed from the money receiver and is in a locked state. 2. The magnet side inserted into the lock plate radiation 11118.18, 20, is pushed by the springs 21, 21 and fits into the recess 16.16 of the annular edge of the lock body, and the magnet side of the lock body, 24 is pushed by the springs 5 and 25 into the recess n of the lock plate,
23, and these magnets 20 and 24 hold the lock plates 1- and □. O@##ffifgtzr&ft

When unlocking, engage the protrusion 4 with the notch 29 and stack the key base on the lock plate 10, and the magnet side of the radial groove, 20, will be attracted to the key magnet 30, 30 and move to the center of the lock plate 10. The two magnets 31 and 31 move against the springs 21 and 21 and come out of the recess 16 of the annular edge, and the magnet inside the lock body, 24 is the key.
This was rejected by the government, and the ban was issued from 23rd. As a result, the lock plate 1O is released from the hold by these magnets 24 and becomes rotatable. Then, the lock plate and its core body 11, which grip the cylindrical case 1 and turn the keel, rotate, and the lock plate lO becomes approximately 6
When rotated 00 times, the stepped surface 14 at the end of the core presses down the notch 8 of the claw piece, causing the tip 7 to sink into the window hole 3 and align it with the surface of the cylindrical case l. 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, turn the key 26 approximately 60 degrees in the opposite direction to remove the lock plate l.
Remove it from O, turn the lock plate lO with 24 on the magnet side, and at the same time make the toe 7 protrude from the cylindrical coos l.

In this embodiment, a suction type electronic lock E and a repellent type electronic lock 1 are combined, and even if a small magnet is attached to the lock plate lO and moved, it will be attracted at the location where this 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.

The above describes one embodiment of the present invention, and the present invention is not limited to this embodiment, and the design can be changed within the spirit of the invention. For example, the number of radial grooves 18 and recesses 16, the number of blind holes 22, etc. It is possible to increase or decrease the number of four points, and by cutting radial grooves on the front of the lock body 4 and inserting magnets and springs,
It may be configured such that a recess is bored in the circumferential surface of the core rod 11 of the lock plate and the inner end of the magnet is fitted therein, and the magnet of the key moves the magnet of the radial groove outward to allow rotation of the lock plate. . In addition, instead of the claw piece 6, a latch can be attached directly to the core rod 11 of the lock plate, or a cam plate can be attached to this core rod to transmit the movement of the lock plate to the latch, so that the latch becomes a metal 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 11-pin lock is a combination of a suction type and a repulsion type, it becomes impossible to detect the position of the magnet inside the lock body from the outside, and it has the effect of reliably preventing unauthorized unlocking of the electronic lock.
