Description

  The present invention relates to a management system for a manual key and a movable body having a lock unlocked by the key. Here, representative examples of the movable body include furniture drawers and doors, and building doors (doors, doors, windows). There are various furniture such as cabinets, wagons, desks, and safes. The door includes various structures such as a horizontal rotation type, a slide type, a flip-up rotation type, and a shutter type.

  There are various types of locks, but from the viewpoint of the unlocking operation method, it can be said that the locks are broadly classified into those that are manually unlocked mechanically by a person and those that can be unlocked electrically. The former manual operation is roughly classified into those that are unlocked using a key such as a cylinder lock and those that can be unlocked without a key such as a dial lock. There are various types of keys depending on the shape of the lock. Many key-type locks are used in offices and various facilities, but it is necessary to prevent early detection and unauthorized use of key loss. Therefore, a device that manages the state of key removal has been proposed (patented) Literatures 1-4).

  The electric lock is unlocked (exactly, unlocked or locked or both) by an actuator such as an electromagnetic solenoid or a motor. However, the structure of the mechanical lock and the electric lock is not completely different. For example, an electric lock that unlocks the dial lock by rotating the rod of the dial lock or a rod member that interlocks with the dead bolt of the cylinder lock is electromagnetic. There are some that use both unlocking with a key and electrical unlocking, such as an electric lock operated by a solenoid.

On the other hand, in offices and other facilities, many locks are used in buildings and furniture, including door locks for entrances and entrances. It is important for security to manage the usage of these locks. . Conventionally, this management means has been dealt with by using an electric lock. For example, taking a door for an entrance / exit as an example, the use of a magnetic card or IC card as an unlocking means makes it possible to open or close the door. History etc. can be managed.

  Many doors and drawers that are locked with key-type locks should also be managed, but in the past, it was only possible to manage the removal of the key itself, and whether the key is actually used. No attempt has been made to grasp the point of use or the point of use history such as frequency of use. This is presumed to be based on the idea that the usage state of the lock can only be realized with an electric lock, and that the usage state cannot be remotely managed with respect to a key-type lock.

  The present invention has been made in view of such a current situation, and is intended to remotely and intensively manage a movable body provided with a lock operated by a key.

  The present invention relates to a key and movable body management system. In the invention of claim 1, the movable body having a lock operated by a manual key and the unlocked state of the lock or movable body are directly set. Alternatively, a use state detection unit that detects indirectly, a management device that manages the unlocked state of the lock or the movable body, and a transmission unit that sends a signal of the use state detection unit to the management device are provided. Here, “managing” is sufficient if at least it can be identified by a monitor or the like by identifying whether it is unlocked or locked.

  In addition to the structure of claim 1, the invention of claim 2 is provided with a key storage device for storing a number of keys corresponding to a number of locks of a large number of movable bodies in addition to the structure of claim 1. The key storage device is provided with key detection means for detecting the presence / absence of each key, and each key detection means of the key storage device and the management device are electrically connected to each key. And the use state of each lock or movable body can be grasped by the management device.

  According to a third aspect of the present invention, in the first or second aspect, the transmission unit wirelessly transmits a signal detected by the usage state detection unit, and a relay receives the signal transmitted from the wireless transmission unit. An antenna is provided, and a signal is transmitted from the relay antenna to the management device by wire, wireless, or a combination of both.

  According to a fourth aspect of the present invention, in any one of the first to third aspects, the movable body is at least one of a furniture drawer, a furniture door, and a building door. In the present invention, “detecting the unlocked state” means that when detecting only the unlocked state, when detecting the state of the locked state, when detecting both the unlocked state and the locked state, Includes three parties. Further, the unlocked state and the locked state include both a locked state / unlocked state of the lock itself and a locked state / unlocked state of a movable body such as a door.

  According to the present invention, since the unlocking state and the locking state are managed by the management device even in the case of a movable body provided with a lock operated with a manual key, the security function in an office or a building can be improved. In addition, managing the unlocked state of the movable body is the same as managing the use state of the key that operates the lock of the movable body, and therefore, early detection of key loss and prevention of unauthorized use of the key. Can also contribute.

  A number of keys are used in organizations such as companies (or facilities / buildings), and these keys are owned by authorized personnel who are allowed to use them during working hours. Although it is stored in a key vault provided in the management area, if the configuration of claim 2 is adopted, the management device can grasp the key takeout / usage state / return history, so that security is ensured. Can be greatly improved.

  As a means for transmitting the signal detected by the use state detection means to the management device, the use state detection means can be used as a terminal and the whole can be connected to the management device by a communication cable. The work is very troublesome, and it is often almost impossible to retrofit to existing doors and furniture. On the other hand, if the configuration of claim 3 is adopted, it is sufficient to arrange the antenna at an appropriate place in the building and attach the use state detecting means and the transmitting means to the appropriate place in the furniture or the building. Troublesome wiring work can be eliminated, and as a result, it can be easily attached to an existing building or furniture.

  Next, an embodiment of the present invention will be described with reference to the drawings. This embodiment shows an example applied to an office of a company or a public office, and FIG. 1 schematically shows the relationship of each element constituting the system.

(1). Outline of system In this embodiment, as an example of a movable body, door 1 provided at the entrance of a building, drawer 3 of cabinet 2, sliding sliding door 5 of cabinet 4, and horizontal pivoting door 7 of cabinet 6 The drawer 9 of the wagon 8 is displayed. The wagon 8 is stored inside the desk 10. In many cases, a drawer with a lock is provided on the desk 10, but in this case, the desk 10 can be incorporated into the system of the present invention. Other furniture such as a safe or a fireproof cabinet, or a cupboard built in a building can be incorporated into the system of the present invention.

  The management system includes a management personal computer 11 as an example of a management device and a key storage 13 for storing a large number of keys 12. Although the management personal computer 11 uses a desktop type, a notebook type personal computer can also be used, and a workstation can also be used as a management device. Needless to say, the management personal computer 11 is not a dedicated product of the system of the present embodiment, but is used for various purposes. The management status can be visualized by displaying it on the display.

  The installation location of the management personal computer 11 can be arbitrarily set. For example, it may be a guard room or a security administrator's desk. It is also possible to share a plurality of management personal computers 11 as management devices and to make them independent. In the case of a large organization, it is also possible to install an intermediate management personal computer for each department individually, for example, to install a central personal computer in a general department such as the general affairs department.

  The key storage 13 includes a main body 15 having a large number of key holding units. Each key holding part has a key hole 14, and only a specific key 12 can be inserted into the specific key hole 14. The main body 15 is provided with key detecting means 16 corresponding to each keyhole 14. The key detection means 16 includes a contact type or non-contact type sensor, and when the specific key 12 is inserted into the key hole 14 at a specific address, the sensor detects the presence of the key 12. It is also possible to set so that the presence is detected by rotating the key 12. It is also possible to provide a lock button corresponding to each keyhole 14 so that the key 12 cannot be removed unless the lock button is pressed.

  Although illustration is omitted, the key storage 13 is provided with a door (or cover), and the key 12 cannot be taken in and out unless the door is opened. A card reader 17 is provided at an appropriate location on the main body 15, and the door cannot be opened unless a specific card is passed through the card reader 17. The card is specified for each user, so that it is possible to know the history of who opened the door and took out which key 12 was returned. Instead of or in addition to the card reader 17, a button type or touch panel type input means may be provided so that the door does not open unless an appropriate number (recitation number) is input.

  Each key detection means 16 and the card reader 17 are connected to the management personal computer 11 via the first branch cable 18 and the main cable 19. Needless to say, the branch cable 18 and the main cable 19 can be dedicated lines, but from the viewpoint of cost, it is preferable to use a telephone line or a power line. In particular, it is preferable to also use a wireless LAN line.

  A relay antenna 21 for wireless reception is arranged in the room where the cabinets 2, 4, 6 and the wagon 8 are installed, and the wireless signals transmitted from the cabinets 2, 4, 6 and the wagon 8 and the door 1 (solution The lock signal and / or the lock signal are received by the relay antenna 21, and the signal is transmitted to the main cable 19 via the second branch cable 22. The relay antenna 21 can be placed at a location where radio signals (radio waves) emitted from the furniture and the door 1 can be accurately received, and the ceiling, the wall, or the top surface of the furniture installed near the wall is suitable.

  When the floor is wide, a plurality of relay antennas 21 can be arranged in one room. It is also possible to use a horizontally long rod-shaped (or wire-shaped) relay antenna. It is also possible to transmit a radio signal from the relay antenna 21 to the relay personal computer 23 installed on the desk via the desktop antenna 24 and transmit the signal to the management personal computer 11 via the telephone line (main cable 19). Alternatively, the desktop antenna 24 and the telephone line can be directly connected without removing the relay personal computer 23. Of course, it is also possible to transmit directly from the relay antenna 21 to the management personal computer 11.

  When there are a large number of rooms, one or a plurality of relay antennas 21 are arranged for each room, and a group of these relay antennas 21 is connected to the main cable 19. Therefore, the management personal computer 11 can grasp the furniture in each room and the unlocked state of the door 1. Necessary programs are stored in the management personal computer 11, and the individual furniture in each room and the unlocked state of the door 1 can be visually confirmed. Of course, it is possible to grasp basic information about who holds which keys, and the usage history of keys and locks is recorded in the memory as needed.

  The relay antenna 21, the second branch cable 22, and the main cable 19 constitute transmission means described in the claims.

(2). First Specific Example of Usage State Detection Unit Next, an arrangement example of the usage state detection unit will be described with reference to FIG. The configuration and arrangement of the use state detection means differ greatly depending on the furniture structure and the lock structure. In the first specific example of FIG. 2A, an example of the wagon 8 is shown.

  In the wagon 8, the cylinder lock 25 is attached only to the uppermost drawer 9. That is, the drawer 9 has a hollow end plate 26, but the cylinder lock 25 is attached inside the end plate 67 with the keyhole 25a exposed to the outside. The cylinder lock 25 has a saddle plate (dead bolt) 25 b that is rotated by the key 12, and when locked, the saddle plate 25 b is in an upward posture and fits into an engagement hole 29 formed in the keratin 28 in the wagon body 27. This causes the drawer 9 to be locked.

  In this example, the use state detecting means 30 is disposed inside the end plate 26 as indicated by a solid line, or is disposed inside the keratin 28 in the wagon body 27 as indicated by a one-dot chain line. The use state detection means 30 is provided with a sensor 31 for detecting the posture of the cover plate 25b. The use state detection means 30 is housed in a case to form one appearance, and a battery, a radio transmission antenna, and a drive and control circuit are built in the case.

  Although the sensor 31 is schematically illustrated in FIG. 2A, it is a reflection type proximity sensor, a translucent sensor using a pair of a light emitting diode and a light receiving diode, or a limit switch (microswitch). Various types such as a simple contact type can be used. Needless to say, the sensor 31 may be turned on when the cylinder lock 25 is locked, or may be turned on when the sensor is unlocked. It is also possible to configure the three units of the sensor 31, the main body, and the battery constituting the use state detecting means 30 as separate units and connect them together (the battery unit is arranged at a place where the battery can be easily replaced) it can.).

  As simply indicated by the alternate long and short dash line, it is also possible to arrange the solar cell 32 on the surface facing the room such as the front surface of the end plate 26 or the front surface of the kerchi 28 and supply power to the use state detecting means 30 from the solar cell. . Further, the use state detecting means 30 can be attached to the front surface of the end plate 26 or the front surface of the wagon body 27.

(3). Second Specific Example of Usage State Detection Means FIG. 2B shows an application example to a cabinet 2 having an all-lock device in which a plurality of (three-stage) drawers 3 are locked and unlocked all at once. ing. In this example, in addition to the cylinder lock 25, the all-lock device includes a pair of left and right horizontal seesaw members 34 arranged on the bottom surface of the top plate portion of the cabinet body 2 a, and a seesaw member 34 by an unlocking operation of the cylinder lock 25. To lock and unlock the drawer bars 3 and the vertical lock bar (vertical rod) 36 arranged on the inner surface of the cabinet body 2a so as to move up and down by the rotation of the crank member 25 and the seesaw member 34. And an engaging member (stopper) disposed on the inner surface of the cabinet body 2a. In the example shown in the figure, the flange plate 25b of the cylinder lock 25 moves up and down by an unlocking operation (when the lock bar 36 is lifted, it is locked).

  Since the all-lock device includes a large number of movable members, the unlocked state can be detected by detecting the movement of any one of the movable members by the use state detecting means 30. In FIG. 2 (B), it is arranged on the top plate lower surface portion of the cabinet body 1 to detect the movement of either the right or left seesaw member 34 and the inside of the cabinet body 2a to detect the movement of one lock bar 36. Three modes are shown: a mode arranged on the surface part and a mode arranged on the inner side surface part of the cabinet body 2a in order to detect the movement of the drawer 3 (any one of the three modes is selected). Of course, it is also possible to detect the movement of the flange plate 25b or the movement of the crank member 35.

(4). Third Specific Example of Use State Detection Means FIG. 3 shows a third specific example applied to the pull-out cabinet 2 having an all-lock device. (A) is the schematic side view seen from the inside, (B) is BB sectional drawing of (A). In this example, the movement of the lock bar 36 is detected, and the lock bar 36 is fitted in a groove portion 37 a formed in the reinforcing member 37 so as to be movable up and down. Reference numeral 38 indicates a suspension rail body.

  In this example, a main unit 30a, a sensor unit (contact limit switch) 31, and a battery unit are used as the use state detecting means 30 on one inner side surface of the cabinet body 2a and outside the lowermost suspension rail body 38. 30b. The main unit 30a and the sensor unit 31, and the main unit 30a and the battery unit 30b are connected to each other. The sensor unit 31 is disposed in a space between the reinforcing member 37 and the outer plate, and is turned on when the lock bar 36 is fully lowered and unlocked.

  The main unit 30a incorporates an oscillation circuit and a transmission antenna. Circuits such as an oscillation circuit and a control circuit are mounted on a single substrate. Needless to say, each unit can be integrated. Moreover, it is also possible to arrange the use state detection means 30 on the upper inner surface of the cabinet body 2a. As a power source, various types of batteries such as a button type can be used, and a solar battery 32 can be used as in the modification of the first specific example.

(5). Fourth Specific Example of Use State Detection Means FIG. 4 shows a fourth specific example applied to a door 1 of an entrance / exit in a building. The lock unit 39 of the door 1 in the building has a knob 40, a collar 41, a latch body (not shown), etc., and the latch body is retracted by the rotation of the knob 40. By rotating the knob, it protrudes and retreats and fits in and out of the engagement hole B1 of the building B.

  In this specific example, the use state detection means 30 is arranged inside a case constituting the lock unit 39. The use state detecting means 30 has a slider 42 that is pushed by the housing 41 when it is retracted and retracts against the spring, and an ON signal is generated when the slider 42 is retracted. is doing.

  Further, the use state detection means 30 includes a piezoelectric element 43 and a battery that generate electricity when the slider 42 moves backward, and power for driving the circuit and power for wireless transmission are generated by the piezoelectric element 43. It will be covered. Therefore, it is not necessary to replace the battery in this example. In this embodiment, even the existing door 1 can be easily incorporated into the system of the present invention by replacing the lock unit 39.

(6). Fifth to Sixth Specific Examples of Use State Detection Means FIG. 5A shows a fifth specific example in which the use state detection means 30 is built in the cylinder lock 25. The cylinder lock 25 has a fixed outer cylinder 45 and a key hole 46a constituting the outside, and is fitted into the inner cylinder 46 and the inner cylinder 46 rotatably fitted in the outer cylinder 45 in a radial posture. A group of drive pins 47, a group of lock pins 48 fitted in a radial posture on the outer cylinder 45, and a spring 49 that pushes the lock pins 48 in the axial direction, and a lock pin when the key is appropriate The group of 48 escapes to the outer cylinder 45 and is allowed to rotate the inner cylinder 46 by a predetermined angle (for example, 90 degrees) (FIG. 5A shows the principle, and is actually more complicated. .)

  In the fifth specific example, an outward projection 50 is provided at an appropriate location of the inner cylinder 46, while the outer cylinder 45 has a recess 51 that allows the protrusion 50 to escape and a recess 51. A case storage part 52 that is partially open is formed, and the use state detection means 30 is attached to the case storage part 52. The use state detection means 30 includes a contact 53 that retreats against the spring by the rotation of the protrusion 50 when the inner cylinder 46 rotates, and a circuit such as a piezoelectric element that generates power by the retraction of the contact 53 and an oscillation circuit. Built in.

  In this fifth specific example, there is no need to perform special processing on furniture such as cabinets or doors, so existing furniture can be easily incorporated into the system of the present invention simply by replacing the cylinder lock 25. .

  FIG. 5B shows a sixth specific example in which the use state detecting means 30 is provided integrally with the key 12. In this specific example, a use state detection means 30 surrounded by a case is provided at a portion of the key 12 that a person picks with a finger, and a push button 30c is provided at the front end of the case. The use state detection means 30 incorporates circuits and an oscillation antenna. When the key 12 is inserted into the keyhole of the lock 25 to such a depth that it can be rotated, the built-in switch is turned on by the movement of the push button 30, the oscillation circuit is activated, and the signal is transmitted to the relay antenna 21.

  In this embodiment, since it is not necessary to apply special processing to the lock 25, furniture, or the like, systemization is extremely easy, and is particularly suitable for systemizing existing furniture and buildings. The use state detection means 30 is provided with a battery, but this battery may be replaceable or rechargeable. It is also possible to employ a method in which an electrode is provided on the front end surface of the use state detecting means 30 and the front end surface portion of the key hole 14 in the key storage 13 and charging is performed when the key storage 13 is stored. .

(7). Block Diagram / Summary FIG. 6 shows a block diagram of the system described above. A use state detection unit 30 and a controller or sensor having a CPU as a core, a wireless communication terminal (transmission antenna), and the like are provided, and a signal is transmitted from the wireless communication terminal to the relay antenna 21, and the signal is, for example, managed PC 11 through a LAN line. To the management device. In many cases, a plurality of relay antennas 21 are arranged. In this case, relay connection means such as a switching hub or router (or server) may be interposed in the circuit. The management device 11 also includes a controller having CPU as a core, memories, a communication interface, an input device, an output device, a display device, and the like.

  The control unit of the key storage 13 includes a communication interface for receiving signals, a controller, memories, a key detection means 16, a door card reader 17, and the like. Each key detection means 16 is a driver (drive circuit) or a key presence / absence detection. Sensor. The key storage 13 is provided with a liquid crystal type display device and can display various information such as messages to the user. If the key that was taken out was actually used but forgotten to be locked, when the key is returned to the key vault 13, "XX is not locked. Please lock it back." It is possible to display a message.

  The management device 11 and the key storage 13 can be integrated into a “key storage management device”. For example, a personal computer installed in the key storage room has both a management function for the state in which the key 12 is put in and out of the key storage room 13, and a management function for the unlocked state of each movable body such as each key 12 and drawer. . When the key storage 13 includes a display device or an input device, the control unit of the key storage 13 can hold the management function of the system of the present application.

  In offices, there are many cases where furniture is unlocked with a key, but the door of the room is an electric lock that is unlocked with a card. The present invention can also be combined with an entrance / exit management system using an electric lock. Therefore, in FIG. 6, the entrance / exit reader and the management personal computer 11 are connected by a LAN line. Then, by providing display means such as letters and voices in the entrance / exit leader (or in the vicinity thereof), for example, when the furniture is unlocked but not locked, the person responsible for the key 12 When he leaves the room, it can be notified by text or voice.

  As can be understood from the above description, in this embodiment, in various facilities where furniture and doors having locks operated by a manual key are arranged and installed, the use state of the keys, furniture and doors, etc. Since the usage status can be remotely grasped and managed, a high security function can be secured.

  In particular, since the management device such as the management personal computer 11 can always grasp the unlocked state of each lock, as described above, when returning the key to a predetermined position (key hole 14) of the key storage room or leaving the key, For example, when locking is forgotten, a message to that effect can be displayed on the display device and appropriate action can be taken. Instead of displaying in characters, it is possible to take measures such as alerting by lighting a lamp or announcing a voice, and it is possible to secure much higher security by these alerting means.

  In addition, detection signals such as the unlocked state, the locked state, or the actual movement state of the movable body such as the drawer are wirelessly transmitted to the relay antenna 21, so that troublesome wiring work is unnecessary and the work is saved. it can. As a result, it becomes easy to incorporate existing facilities into the system. In addition, the system according to the present embodiment is characterized in that a telephone line and a wireless LAN system can be partially shared, thereby significantly reducing the system construction cost. When the wireless LAN system includes an antenna, the LAN antenna can also be used as the relay antenna of the present invention.

(8). Others The present invention can be embodied in various ways other than the above embodiment. For example, providing a power generation device such as a piezoelectric element in furniture or the like can be widely applied to the first to third specific examples. For example, taking a cabinet with a drawer as an example, it is also possible to provide a piezoelectric element that generates electric power by pulling out or pushing in the drawer, and storing the electric power in a battery to serve as a driving power source for the use state detecting means. If comprised in this way, since a big force generate | occur | produces in the back-and-forth movement of a drawer, and opening and closing of a door, there exists an advantage which can ensure required electric power firmly.

  When building doors are incorporated into the system, they can be linked to an external management system such as a security company. The key vault can be built in the building. There are various types of locks such as push-in locks and padlocks in addition to cylinder locks, but the present invention can be applied to various locks (thus including locks in which only unlocking is performed with a key). It is also possible to incorporate the system of the present application into an alarm system or to incorporate alarm means into the system of the present application. In addition, radio wave energy transmitted from the relay antenna can be used as a driving power source for the use state detecting means.

It is a schematic perspective view which shows the system of this invention typically. It is a figure which shows the 1st and 2nd specific example of a use condition detection means. It is a figure which shows the 3rd specific example of a use condition detection means. It is a figure which shows the 4th specific example of a use condition detection means. It is a figure which shows the 5th-6th specific example of a use condition detection means. It is a block diagram which shows the outline of a system.
