Description

  The present invention relates to a locking device and an intrusion prevention device. Specifically, the present invention relates to a locking device and an intrusion prevention device that have a sufficient crime prevention effect while being easy to use and having a simple structure.

  The door of a house or a vehicle is provided with a structure for restricting the opening and closing of the door for the purpose of preventing a suspicious person from entering from the outside. The most common structure is a combination of a lock provided on the door and a key for opening the lock.

  In recent years, there is an electronic lock that allows a door to be opened by inputting a password on a touch panel or a numeric keypad. Since electronic locks do not require a physical key and can set a plurality of passwords, they are popular not only in doors but also in station lockers and apartment delivery boxes.

  However, with the electronic lock, the numbers entered are arranged in numerical order, or the numbers are printed directly on the keys, so a third party located around the operator sees the finger movement of the input operation. In some cases, it was possible to guess the number.

  Under these circumstances, there is an electronic lock device that suppresses the leakage of the personal identification number to a third party due to the input operation of the personal identification number. For example, an electronic locking device described in Patent Document 1 has been proposed.

  Here, Patent Document 1 describes an electronic lock device 100 as shown in FIG. The electronic lock device 100 includes an electronic lock 101, a display 102 for inputting a password, a number authentication unit 103, and a locking / unlocking command unit 104.

  The electronic lock device 100 also includes an arrangement changing unit 105 that changes the arrangement of the numbers displayed on the display 102 after the number is authenticated. Since the arrangement of the numbers on the display 102 is changed after the correct code number is input, the code number is prevented from being decrypted by a malicious third party.

Further, a permanent magnet 3 is attached in the vicinity of one end 9 of the locking part 2, and a permanent magnet 4 is attached to the other end. The permanent magnet 3 and the permanent magnet 4 are attached with a nonmagnetic metal case 8 that protects the permanent magnet.

  The electromagnet 5 and the electromagnet 6 are formed by winding a coil around an iron core, and become magnetized when energized. Further, the locking part 2 is disposed so as to penetrate through the iron cores of the electromagnet 5 and the electromagnet 6. Moreover, the permanent magnet 3 and the electromagnet 5, and the permanent magnet 4 and the electromagnet 6 are opposed to each other, and the same poles of the permanent magnet and the electromagnet face each other when energized.

  In addition, the electromagnet 5 and the electromagnet 6 are connected to different wiring paths, and have a structure in which supply and stop of energization can be switched independently.

  Moreover, the locking part fixing port 7 is formed in the door 10 which is a hinged door in the shape which can be fitted with the one end 9 of the locking part 2. The locking part 2 is attached so as to be movable in the direction of the locking part fixing port 7 or in the opposite direction.

  The single locking device 1 is provided with a cushion mat 25 that prevents the permanent magnet 3 from colliding with the door 10 when the locking portion 2 moves to the locking portion fixing port 7 side.

  Here, it is not always necessary to attach a permanent magnet to the locking part 2, and an integrated shape in which a part of the locking part 2 becomes a magnetic region can also be adopted. However, it is preferable that the permanent magnet is attached to the locking portion 2 in that the permanent magnet can be removed and the maintainability of the apparatus is improved.

  Moreover, the single locking device 1 does not necessarily need to include an electromagnet. However, it is preferable that the single locking device 1 is provided with an electromagnet from the viewpoint that the presence or absence of magnetism can be switched by the energization control and the operation of the device becomes easy.

  Moreover, the single locking device 1 does not necessarily need to be provided with two permanent magnets and two electromagnets. However, it is preferable that the single locking device 1 includes two permanent magnets and two electromagnets from the viewpoint that both the unlocking and locking movements of the locking portion 2 can be controlled by magnetic force and the operation of the device becomes easy.

The state is released. That is, the door 10 can be unlocked. Note that after unlocking, the electromagnet 6 is de-energized, and the locking portion 2 remains in the moved position.

  In order to lock the door 10 from the unlocked state, the electromagnet 5 is magnetized by energizing the wiring path connected to the electromagnet 5. Since the electromagnet 5 and the permanent magnet 3 are arranged at positions where the same poles face each other after energization, a repulsive force is generated.

  Due to this repulsive force, the locking part 2 to which the permanent magnet 3 is attached moves in the direction of the locking part fixing port 7, and the fitting state between the one end 9 of the locking part 2 and the locking part fixing port 7 is Become. That is, the door 10 is in a locked state in which the opening and closing of the door 10 is restricted.

  As described above, the double-type locking device 13 according to the second embodiment has a structure in which the locking portion 14 can move in the direction of the locking portion fixing port 19 or in the opposite direction.

  In order to unlock the door 21 from the locked state, current is passed through the wiring path connected to the electromagnet 18 to make the electromagnet 18 magnetic. After energization, the electromagnet 18 and the permanent magnet 16 are arranged at positions where the same poles (S poles or N poles) face each other, so a repulsive force is generated.

  Due to this repulsive force, the two locking portions 14 to which the permanent magnets 16 are attached move in the opposite direction to the locking portion fixing port 19, and one end 20 of the locking portion 14, the locking portion fixing port 19, The fitting state is released. That is, the door 21 can be opened and unlocked. Note that after unlocking, the electromagnet 18 is de-energized, and the locking portion 14 remains in the moved position.

  Further, in order to lock the door 21 from the unlocked state, current is passed through the wiring path connected to the electromagnet 17 to make the electromagnet 17 magnetic. Since the electromagnet 17 and the permanent magnet 15 are arranged at positions where the same poles face each other after energization, a repulsive force is generated.

  By this repulsive force, the two locking portions 14 to which the permanent magnets 15 are attached move in the direction of the locking portion fixing port 19, and the one end 20 of the locking portion 14 and the locking portion fixing port 19 are fitted. It becomes a state. That is, the door 21 is in a locked state in which opening and closing is restricted. In addition, after locking, the energization to the electromagnet 17 is stopped, and the locking part 14 remains in the position after the movement.

  Even when the electromagnet 17 and the electromagnet 18 are deenergized at the time of locking and unlocking, the position of the locking portion 14 does not change, so that not only power is saved, but also trouble due to overheating of the electromagnet can be prevented. .

  Thus, in the second embodiment of the present invention, both the locking and unlocking of the hinged door can be performed by magnetic force, and the opening and closing of the door can be more strongly restricted by the two locking portions. .

  As described above, the manual locking device 26 according to the third embodiment has a structure in which the locking portion 27 and the locking auxiliary member 34 can move in the direction of the locking portion fixing port 30 or in the opposite direction.

  In order to unlock the door 32 from the locked state, current is passed through the wiring path connected to the electromagnet 29 to make the electromagnet 29 magnetic. Since the electromagnet 29 and the permanent magnet 28 are arranged at positions where the same poles face each other after energization, a repulsive force is generated.

  Due to this repulsive force, the two locking portions 27 to which the permanent magnets 28 are attached move in the opposite direction to the locking portion fixing port 30, and one end 31 of the locking portion 27, the locking portion fixing port 30, The fitting state is released. That is, the door 32 can be opened and unlocked. Note that after unlocking, the electromagnet 29 is de-energized, and the locking portion 27 remains in the moved position.

  Further, in order to lock the door 32 from the unlocked state, the knob 36 of the locking auxiliary member 34 is grasped by hand and is slid and moved in the direction of the locking portion fixing port 30. Thereby, the part of the permanent magnet 28 is pushed by the locking auxiliary member 34, and one end 31 of the locking part 27 is fitted into the locking part fixing port 30.

Hereinafter, a usage pattern of the fifth embodiment will be described.
FIG. 8 is a schematic view showing a position where the fifth embodiment of the present invention is used in a region between the opening door of the front seat of the vehicle and the sliding door of the rear seat.

  As described above, the double drop type device 48 according to the fifth embodiment has a structure in which the locking portion 49 is movable in the vertical direction.

  In order to unlock the door 54 from the locked state, current is passed through the wiring path connected to the electromagnet 51 to make the electromagnet 51 magnetic. Since the electromagnet 51 and the permanent magnet 50 are arranged at positions where the same poles face each other after energization, a repulsive force is generated.

  By this repulsive force, the two locking portions 49 to which the permanent magnets 50 are attached move vertically upward, and the fitting state between the lower end 53 of the locking portion 49 and the locking portion fixing port 52 is released. . That is, the door 54 can be unlocked.

  Further, the door 54 is locked by stopping energization of the electromagnet 51. That is, when the energization of the electromagnet 51 is stopped, the repulsive force between the electromagnet 51 and the permanent magnet 50 disappears, and the locking portion 49 naturally falls in the direction of the locking portion fixing port 52 due to gravity and is fitted. .

By providing one double drop type device 48, it is possible to restrict the opening and closing of both the front door opening door 56 and the rear seat sliding door 57 of the vehicle. In addition, the sliding door of the back seat of FIG. 8 can also be locked using the single locking device 1 which is 1st Embodiment.

  Thus, in the fifth embodiment of the present invention, the door is unlocked with a magnetic force, and the door can be locked by stopping energization of the electromagnet. The opening and closing of the two doors can be restricted. It can also be used for both the front door of the car and the sliding door of the rear seat.

<Sixth Embodiment>
Next, a sixth embodiment of the locking device to which the present invention is applied will be described.
FIG. 9 is a schematic view showing a sixth embodiment of the locking device to which the present invention is applied.

  As shown in FIG. 9 (a), an L-shaped locking device 60, which is an example of a locking device to which the present invention is applied, extends vertically through an L-shaped locking portion 61 and an L-shaped locking portion 61. Two pole members 62 and a levitation permanent magnet 63 attached to the upper end of the pole member 62 are provided.

  A levitation electromagnet 64 is disposed between the L-shaped locking portion 61 and the levitation permanent magnet 63. A lower plate member 65 for stabilizing the horizontal movement of the L-shaped locking device 61 is disposed at the lower end of the pole member 62.

  Further, end permanent magnets 66 having strong magnetism are attached to the end portions of the L-shaped locking portion 61 and the lower plate member 65, respectively, and locking electromagnets 67 are disposed at the opposing positions. Further, the levitation electromagnet 64 and the locking electromagnet 67 are connected to different wiring paths, and have a structure in which supply and stop of energization can be switched independently.

  Further, one end 68 of the L-shaped locking part 61 is bent vertically downward and is fitted into a locking part fixing port 70 formed in the sliding door 69 to restrict the opening and closing of the sliding door 69.

  Further, the levitating permanent magnet 63 and the levitating electromagnet 64, the end permanent magnet 66 and the locking electromagnet 67 are opposed to each other, and when energized, the permanent magnet and the electromagnet have the same polarity (S poles or N poles) facing each other. It has become. The L-shaped locking part 61 has a structure that can move in the vertical and horizontal directions.

  In addition, a guide plate member 72 that guides the movement in the horizontal direction is provided above the L-shaped locking portion 61 and the lower plate member 65, respectively, and serves to suppress rolling. FIG. 9B shows details of the guide plate member 72. In the guide plate member 72, a guide groove 73 having a width substantially the same as the thickness of the pole member 62 is formed.

  Here, the guide plate member 72 is not necessarily provided in the L-shaped locking device 60. However, it is preferable that the L-shaped locking device 60 is provided with a guide plate member 72 from the viewpoint that it is difficult for the L-shaped locking portion 61 to roll and it is easy to lock and unlock.

  Hereinafter, a usage pattern of the sixth embodiment will be described.

  As described above, the L-shaped locking device 60 according to the sixth embodiment has a structure in which the L-shaped locking portion 61 is movable in the vertical direction and the horizontal direction.

  In order to unlock the sliding door 69 from the locked state, current is passed through the wiring path connected to the levitation electromagnet 64 and the levitation electromagnet 64 is magnetized. After energization, the levitation electromagnet 64 and the levitation permanent magnet 63 are arranged at positions where the same poles face each other, so a repulsive force is generated.

  Due to this repulsive force, the L-shaped locking portion 61 to which the levitation permanent magnet 63 is attached floats vertically upward. At the position where the L-shaped locking portion 61 is lifted, the two end permanent magnets 66 are opposed to the locking electromagnet 67 in a non-energized state.

  Here, the strong magnetic force of the end permanent magnet 66 acts on the locking electromagnet 67 in an unenergized metal state, and the L-shaped locking portion 61 is on the side of the locking electromagnet 67 opposite to the locking portion fixing port 70. The sliding door 69 is unlocked. In addition, although the structure which moves the L-shaped locking part 61 manually can also be taken, it becomes possible to unlock automatically by using the end permanent magnet 66 with strong magnetism.

  Further, to lock the sliding door 69, first, the L-shaped locking portion 61 is lifted by energizing the wiring path connected to the floating electromagnet 64. This is because in the state as it is, it cannot be fitted into the locking portion fixing port 70 of the sliding door 69.

  Next, current is passed through a wiring path connected to the unlocking electromagnet 67 to cause the unlocking electromagnet 67 to become magnetized. After energization, the unlocking electromagnet 67 and the end permanent magnet 66 are arranged at positions where the same poles face each other, so a repulsive force is generated.

  With this repulsive force, the L-shaped locking part 61 can be locked by moving in the direction of the locking part fixing port 70 and stopping the energization of the levitation electromagnet 64.

  Thus, in the sixth embodiment of the present invention, both the locking and unlocking of the sliding door can be performed by magnetic force, and the opening and closing of the door can be more strongly restricted by the L-shaped locking part. . It can also be used for car sliding doors.

<Seventh Embodiment>
Next, a seventh embodiment of the locking device to which the present invention is applied will be described.
FIG. 10 is a schematic view showing a seventh embodiment of the locking device to which the present invention is applied.

  As shown in FIG. 10, a suction type device 76 that is an example of a locking device to which the present invention is applied has three U-shaped electromagnets 77 provided on a wall surface. Further, six permanent magnets 78 having strong magnetism are arranged on the side surface of the sliding door 75 adjacent to the wall surface.

  In addition, the U-shaped electromagnet 77 and the permanent magnet 78 face each other, and the same polarity (S poles or N poles) face each other when energized.

  In addition, the U-shaped electromagnet 77 and the permanent magnet 78 are arranged so as to avoid a region having a height in the middle of the wall surface and the sliding door 75.

  Here, the shape of the electromagnet is not necessarily U-shaped. However, since both the S pole and the N pole of the electromagnet can be used for locking or unlocking the sliding door 75, and the opening and closing of the sliding door 75 can be more strongly restricted, the shape of the electromagnet may be U-shaped. preferable.

  In addition, the permanent magnet provided on the side surface of the sliding door 75 does not necessarily have strong magnetism. However, it is preferable that the permanent magnet provided on the side surface of the sliding door 75 has strong magnetism because the opening and closing of the sliding door 75 can be more strongly restricted.

  In addition, the U-shaped electromagnet 77 and the permanent magnet 78 do not necessarily have to be disposed so as to avoid the area of the wall surface and the middle height of the sliding door 75. However, the U-shaped electromagnet 77 and the permanent magnet 78 have a wall and a height in the middle of the sliding door 75 because the noble metal worn on a wristwatch or the like is not easily affected by the magnetic force when the sliding door 75 is opened and closed. It is preferable to arrange them so as to avoid this region.

  Hereinafter, usage patterns of the seventh embodiment will be described.

  The attraction type device 76 according to the seventh embodiment has a structure that can be opened and closed by a magnetic force generated between the U-shaped electromagnet 77 and the permanent magnet 78.

  When the U-shaped electromagnet 77 is not energized, the metal U-shaped electromagnet 77 is attracted by the strong magnetic force of the permanent magnet 78, and the sliding door 75 is locked.

  On the other hand, when the U-shaped electromagnet 77 is energized, the repulsive force generated between the U-shaped electromagnet 77 and the permanent magnet 78 causes the sliding door 75 to move away from the wall surface and be unlocked.

  Thus, in the seventh embodiment of the present invention, the opening and closing of the sliding door by magnetic force can be restricted with a simple structure.

Next, a password input device that can be connected to an electromagnet used in each embodiment of the present invention will be described.
FIG. 11 is a schematic diagram showing the structure of the relay switch.

  In addition, each switch 80 can switch between connection and disconnection of the wiring route via the switch by moving the switch up and down. Further, the switches 80 for energizing the electromagnets are connected by wiring to form a circuit.

  The alarm speaker 82 is connected to a separate wiring path different from the wiring path connected to the electromagnet. As a result, the alarm speaker 82 is energized to generate an alarm sound when the switch other than the password is connected to the switch 80 and the wrong switch is selected.

  The emergency standby switch 83 is a switch for connecting the dry battery 91 disposed in the relay switch 79 to the circuit, and plays a role in supplying the relay switch 79 with electricity in the event of a power failure. The illumination switch 84 is a switch that turns on the illumination during night operation.

  Here, the relay switch device 79 is not necessarily employed as a device for inputting the personal identification number. However, the relay switch device 79 is preferably employed from the viewpoint that a password can be input with a simple structure.

  Further, the relay switch device 79 does not necessarily need to include the alarm speaker 82. However, it is preferable that the relay switch device 79 includes an alarm speaker 82 from the viewpoint of easily preventing unlocking by inputting an appropriate number and enhancing the crime prevention effect.

  Further, the relay switch device 79 does not necessarily need to include the emergency emergency switch 83 and the illumination switch 84. However, it is preferable that the relay switch device 79 includes the emergency standby switch 83 and the illumination switch 84 from the viewpoint that it can be used at the time of a power failure and can be easily operated even in a dark place.

  FIG. 11B is a rear view of the relay switch device 79. On the back side of each switch box 81, an input / output jack 85 is provided for each box so that wiring can be freely connected.

  By connecting the power input / output jack 85 of the switch box 81 with a wiring and forming a circuit with an electromagnet, the number assigned to the box becomes a personal identification number. That is, if the switch 80 corresponding to the personal identification number is switched correctly, the electromagnet related to the unlocking of each embodiment described above is energized and the door can be unlocked.

  Further, in the structure of the relay switch device 79, the switch 80 used for unlocking can be changed simply by changing the wiring connected to the power input / output jack 85 of the switch box 81, and the password can be easily changed. Can do.

  Further, on the rear surface of the relay switch device 79, a distribution board 86 for energizing a plurality of wiring paths, a transformer 87, a capacitor 88, a diode 89, and an AC power cord 90 are provided.

  Thus, by connecting the relay switch device 79 to the electromagnet used for locking the door, it is possible to construct a device that can be unlocked by inputting the password.

  As an example in which the relay switch device 79 is combined with a locking device, a case where the single locking device 1 according to the first embodiment and the relay switch device 79 are combined and provided on a front door will be described.

  The single locking device 1 locks the door of the entrance by the locking part 2. In addition, outdoors, it is possible to switch the outdoor unlocking path used for unlocking outdoors, in which the electromagnet 6 used for unlocking and the relay switch device 79 are connected, and the electromagnet 5 used for locking and turning on and off. There is an outdoor locking path that is used for outdoor locking connected to an outdoor locking dedicated switch. The outdoor lock only switch is an automatic push type that can be quickly switched on and off in preparation for a quick outing.

  In addition, indoors, an electromagnet 6 used for unlocking and an indoor unlocking path connected to an indoor unlocking switch that can be switched on and off, and an electromagnet 5 used for locking. There is an indoor locking path used for indoor locking, which is connected to an indoor locking dedicated switch that can be switched ON and OFF. That is, it has a path for locking and unlocking outdoors and indoors, respectively.

In the relay switch device 79, by turning on the switches 80 corresponding to a plurality of numbers set in advance as passwords, the outdoor unlocking path is connected, and the electromagnet 6 of the single locking device 1 is energized. Due to the magnetic force generated between the energized electromagnet 6 and the permanent magnet 4, the locking portion 2 is detached from the locking portion fixing port 7, and the door can be unlocked. After unlocking, the power to the electromagnet 6 is turned off by manually turning off the switch 80.

  Next, when locking after entering the room, the indoor locking path is connected by turning on the indoor locking switch installed indoors, and the electromagnet 5 of the single locking device 1 is energized. With the magnetic force generated between the energized electromagnet 5 and the permanent magnet 3, the locking portion 2 is fitted into the locking portion fixing port 7, and the door is locked. Even if the switch 80 is turned off after unlocking outdoors and the repulsive force disappears between the electromagnet 6 and the permanent magnet 4, the door can be opened without being locked.

  Also, when unlocking the locked door indoors when going out, the indoor unlocking path is connected by turning on the indoor unlocking dedicated switch installed indoors, and the electromagnet of the single locking device 1 6 is energized. Due to the magnetic force generated between the energized electromagnet 6 and the permanent magnet 4, the locking portion 2 is detached from the locking portion fixing port 7, and the door can be unlocked.

  Further, when locking outdoors, by turning on the outdoor locking dedicated switch, the outdoor locking path is connected and the electromagnet 5 of the single locking device 1 is energized. With the magnetic force generated between the energized electromagnet 5 and the permanent magnet 3, the locking portion 2 is fitted into the locking portion fixing port 7, and the door is locked. In addition, after locking, the power supply to the electromagnet 5 is turned off by manually turning off the normal switch. Furthermore, it can also be set as the structure which a switch only for outdoor locking turns off automatically.

  With the above flow, the single locking device 1 and the relay switch device 79 can be combined to be used for locking and unlocking the entrance door.

The left dial main body 99 can be rotated so that the south pole or the north pole of the first magnet 100 faces the locking portion fixing port 96.

  The right dial device 97 is installed on the right door 94. In addition, a through hole 102 is formed inside the right dial main body 101 of the right dial device 97, and the second dial 103 is movable between the locking portion fixing port 96 and the through hole 102. The second magnet 103 plays a role of a lock that restricts the opening and closing of the left door 93 and the right door 94 by being inserted through the locking portion fixing port 96.

  Further, the right dial main body portion 101 can be rotated and the through hole 102 can be arranged toward the locking portion fixing port 96. When the locking portion fixing port 96 and the through hole 102 are positioned on substantially the same line, the second magnet 103 can move between the two. Further, when the right dial main body 101 is rotated, the through-hole 102 stops at a position where it is located substantially on the same line as the locking portion fixing port 96.

  Further, the push-back member 98 is installed adjacent to the right dial device 97, and can be moved in the direction of the right dial device 97 along the slide groove 105 provided in the right door 94 by grasping the knob 104 by hand. . The push-back bar 114 is inserted into the through hole 102 and can push the second magnet 103 located in the through hole 102 back to the locking portion fixing port 96.
