  DESCRIPTION OF EXEMPLARY EMBODIMENTS Hereinafter, an embodiment of the invention will be described with reference to the drawings. FIG. 1 is a front view around the entrance door 18 of the building 10. FIG. 1 is a view of the entrance door 18 as seen from the outdoor side, and includes an electrical configuration related to the entrance door 18.

  As shown in FIG. 1, in a building 10 such as a house, a building entrance 12 is formed on an outer wall 11 that divides the interior space and the outdoor space, and the building entrance 12 communicates the interior space and the outdoor space. ing. Here, the building entrance 12 is provided at the entrance of the building 10 and is opened and closed by an entrance door 18 as an opening / closing device. The building entrance 12 is provided with a door frame 22 extending along the inner peripheral surface thereof, and the entrance door 18 is rotatably supported by a door hinge 23 with respect to the door frame 22. The entrance door 18 is of a single-open type, and a plurality of door hinges 23 are provided at one of the left and right ends of the entrance door 18.

  The entrance door 18 is configured to include a rectangular plate-shaped door body 24, and a door handle 25 and a cylinder lock 26 are provided on the door body 24 as a main opening / closing body. The cylinder lock 26 as the main locking means is an electric locking device. On the other hand, the cylinder lock 26 is provided with a key hole, and the cylinder lock 26 is shifted to a locked state or an unlocked state by being operated in a state where the key is inserted into the key hole. The cylinder lock 26 may be provided not on the entrance door 18 side but on the outer wall 11 side.

  The entrance door 18 is formed with an emergency entrance 28 as an opening that penetrates the door main body 24 in the thickness direction. The emergency entrance 28 has a size and a shape that allow people to pass through. . In this case, the door main body 24 has a generally square shape as a whole, and there are entrance / exit forming portions for forming the emergency entrance / exit 28 on the top / bottom and left / right sides of the emergency entrance / exit 28, respectively.

  The entrance door 18 is provided with an emergency door 31 as an emergency opening / closing body for opening and closing the emergency doorway 28. The entrance door 18 and the emergency door 31 are integrally formed. The emergency doorway 28 is provided with a door frame 32 extending along the inner peripheral surface thereof, and the emergency door 31 is rotatably supported by a door hinge 33 with respect to the door frame 32. Yes. The emergency door 31 is a single-open type, and a plurality of door hinges 33 are provided at one of the left and right ends of the emergency door 31. In this case, the emergency door 31 shifts to the open state by rotating from the closed state to the outdoor side.

  The emergency door 31 is provided with an emergency locking device 35. The emergency locking device 35 is an electric locking device and does not have a keyhole. The door hinge 33 and the emergency locking device 35 are provided so as not to be exposed on the outdoor side surface of the emergency door 31, and the door knob is not provided on the outdoor side surface of the emergency door 31. The emergency locking device 35 may be provided not on the emergency door 31 side but on the entrance door 18 side.

  The entrance door 18 is provided with a posting port 37 for posting mails and newspapers. The posting port 37 is a through hole that penetrates the emergency door 31 in the thickness direction.

  Here, in the entrance door 18, the strength of the door body 24 is lower than the strength of the door frame 32. According to this configuration, for example, when the building entrance 12 and the door frame 22 are deformed due to damage to the outer wall 11 in the event of a disaster such as an earthquake, the door main body 24 is easily deformed. The frame body 32 is difficult to deform. Therefore, even if the deformed door frame 22 comes into contact with the door body 24 and the entrance door 18 cannot be opened, the door frame 32 is held so that the emergency door 31 can be opened. Become.

  In the present embodiment, the building 10 has a locking system for controlling the locking of the emergency locking device 35. For example, when the entrance door 18 cannot be opened in the event of a disaster, it is adapted to the situation. The emergency door 31 is unlocked or locked by the emergency locking device 35.

  First, the electrical configuration of the locking system will be described. In the locking system, the emergency locking device 35 is connected to a home server 41 as locking control means. The home server 41 includes a microcomputer including a CPU and various memories, and outputs a command signal to the emergency locking device 35. Further, the home server 41 has a storage unit 42, and the storage unit 42 stores information related to locking control.

  The home server 41 includes a door load sensor 44 that detects a load applied to the door main body 24 of the entrance door 18, a human sensor 45 that detects that a person is in the building space, and a communication capable of wireless communication. A device 46 is connected.

  The door load sensor 44 is configured by a pressure sensor that detects an applied pressure, and is provided so as to extend along the outer peripheral surface of the door body 24 at the entrance door 18. The door load sensor 44 detects a load applied to the door main body 24 by the door frame 22 when, for example, the door frame 22 is deformed and contacts the vicinity of the outer peripheral surface of the door main body 24.

  The human sensor 45 is provided in a living room, a hallway, a front door, or the like in the building 10. The human sensor 45 is installed such that when a person in the building 10 goes outside through the building entrance 12, a place where the person passes is included in at least the detection range.

  The communication device 46 can wirelessly communicate with a smart key K that transmits an unlocking signal that can unlock the cylinder lock 26 and the emergency locking device 35, and is installed near the entrance door 18, for example. Yes. The communication device 46 receives the unlock signal of the smart key K, for example, when the distance from the smart key K is smaller than a predetermined distance, and outputs the received unlock signal to the home server 41. Here, the smart key K corresponds to a mobile communication device.

  The unlock signal includes entrance identification information as main identification information for unlocking the cylinder lock 26 and emergency identification information for unlocking the emergency lock device 35. The storage unit 42 stores identification information corresponding to each of the entrance identification information and emergency identification information, and the home server 41 stores the identification information of the unlock signal and the identification information of the storage unit 42. Authentication processing is performed by checking each of the above. If the entrance identification information or the emergency identification information is authenticated by the authentication process, the person near the communication device 46 has the smart key K. Therefore, the home server 41 recognizes the presence of the resident who has the smart key K outdoors near the entrance door 18, for example, even if a suspicious person is near the entrance door 18 outdoors. not recognize. The smart key K may be configured to transmit identification information when the operation unit is operated.

  The communication device 46 can be connected to the Internet and wirelessly communicated with an external facility. The communication device 46 can receive earthquake information through the Internet or an external facility, and outputs a signal including the earthquake information to the home server 41. In addition, as earthquake information, the information regarding the earthquake which already generate | occur | produced and the information which predicted earthquake occurrence are mentioned.

  Next, the control process of the locking system executed by the home server 41 will be described with reference to FIG. FIG. 2 is a flowchart showing a processing procedure of the locking control processing when an earthquake occurs. This locking control process is executed at a predetermined cycle with the execution condition that the home server 41 has acquired the occurrence of an earthquake based on the signal from the communication device 46.

  In FIG. 2, in step S11, various signals from the door load sensor 44, the human sensor 45, and the communication device 46 are acquired. In step S <b> 12, it is determined based on the detection signal of the door load sensor 44 whether the entrance door 18 is in a state where it cannot be opened. In the non-openable determination, it is determined whether or not the door frame 22 is deformed by determining whether or not a load is applied to the door body 24, and when the load is applied to the door body 24, The load is calculated based on the detection signal of the door load sensor 44, and it is determined whether the calculated load is greater than a reference value. When the calculated load is larger than the reference value, it is determined that the entrance door 18 cannot be opened because the door frame 22 is distorted so that the entrance door 18 cannot be opened.

  If the entrance door 18 is in a state that can be opened, the process proceeds to step S13, and authentication processing for the entrance door 18 is executed based on the entrance identification information of the unlock signal received from the smart key K. In step S14, it is determined whether or not to authenticate the entrance identification information. Here, the release signal is received when a resident or the like who has the smart key K is in the vicinity of the entrance door 18, and if the unlock signal is not received, it is determined that the entrance identification information is not authenticated. .

  If the entrance identification information is not authenticated, the entrance door 18 is not unlocked in step S15 (the cylinder lock 26 is not shifted to the unlocked state), and if the entrance identification information is authenticated, the entrance door 18 is removed in step S16. Unlock (cylinder lock 26 is shifted to the unlocked state). In other words, if the entrance door 18 can be opened even in the event of an earthquake, the entrance door 18 is locked in the same way as during normal times, allowing residents to enter and exit the building 10 through the building entrance 12. Regulates the entry and exit of suspicious individuals. Incidentally, when the entrance door 18 is in a state that can be opened, the emergency locking device 35 is held in a locked state.

  If the entrance door 18 is in a state where it cannot be opened, the process proceeds to step S17, and whether or not a person has been detected in the building 10 is determined based on the detection signal of the human sensor 45. Here, since the detection range of the human sensor 45 includes a corridor and an entrance, even if a person is in a toilet or the like outside the detection range, if the person moves toward the entrance door 18, the presence thereof Will be detected.

  When there is a person in the building 10, the process proceeds to step S <b> 21 and the emergency door 31 is unlocked (the emergency locking device 35 is shifted to the unlocked state). In this case, a person can go out of the building 10 to the outside through the emergency doorway 28 without unlocking the emergency door 31.

  On the other hand, when there is no person in the building 10, the process proceeds to step S18, and the authentication process for the emergency door 31 is executed based on the emergency identification information of the unlock signal received from the smart key K. In step S19, it is determined whether or not the emergency identification information is authenticated. When the unlock signal is not received from the smart key K, it is determined that the emergency identification information is not authenticated. If the emergency identification information is not authenticated, the emergency door 31 is not unlocked in step S20 (the emergency locking device 35 is not shifted to the unlocked state), and if the emergency identification information is authenticated, the process goes to step S21. Then, the emergency door 31 is unlocked (the emergency locking device 35 is shifted to the unlocked state). In other words, if the entrance door 18 cannot be opened in the event of an earthquake, the emergency locking device 35 is controlled to lock in and the entrance / exit of the suspicious person while allowing the residents to enter and exit the building 10 through the emergency entrance 28. Is regulated.

  According to the embodiment described in detail above, the following excellent effects can be obtained.

  When the emergency doorway 28 formed in the entrance door 18 is opened and closed by the emergency door 31, the lock control of the emergency lock device 35 is controlled when the entrance door 18 cannot be opened due to the occurrence of an earthquake. Done. In this case, by unlocking the emergency door 31 with the emergency locking device 35, a person can enter and exit the building 10 through the emergency entrance 28 even if the entrance door 18 cannot be opened. . On the other hand, by locking the emergency door 31, for example, a suspicious person can be prevented from entering the building 10. Therefore, in the event of a disaster such as an earthquake, the emergency door 31 can be locked even if there is no room for the person who goes outside from the building 10 to perform the locking operation, thus preventing the intrusion of a suspicious person. I can demonstrate my power. Furthermore, since the locking control of the emergency door 31 is not performed in a state where the entrance door 18 can be opened, the emergency door 31 can be held in a locked state.

  As a result, in the configuration in which the emergency door 31 is provided integrally with the entrance door 18, the crime prevention performance of the entrance door 18 can be suitably improved.

  Since the entrance identification information for the entrance door 18 and the emergency identification information for the emergency door 31 are individually set, the locking control of the entrance door 18 and the locking control of the emergency door 31 are not confused independently. Can be done. Therefore, when the unlock signal is output from the smart key K, the emergency door 31 can be unlocked if the entrance door 18 cannot be opened. On the other hand, if the entrance door 18 can be opened, only the entrance door 18 can be unlocked, and the emergency door 31 can be prevented from being unlocked unnecessarily.

  Since the door identification information is included in the unlock signal from the smart key K, it is considered that the resident or the like has the smart key K in the normal state in order to unlock the entrance door 18. In this situation, since the unlock signal from the smart key K includes emergency identification information in addition to the entrance identification information, the resident or the like suddenly encounters a situation where the entrance door 18 cannot be opened due to an earthquake or the like. However, the emergency door 31 can be unlocked by the smart key K.

  Since the process related to the locking control of the emergency door 31 is executed on the condition that an earthquake occurs, it is possible to prevent the emergency door 31 from being opened unnecessarily when no earthquake occurs.

  In a state where the entrance door 18 cannot be opened due to the occurrence of an earthquake, the emergency door 31 is unlocked along with the execution of the authentication process when a resident or the like who has the smart key K enters the building 10. Residents who have evacuated can return to the building 10, and residents can enter the building 10 to save lives. On the other hand, since the emergency door 31 is not unlocked for a person who does not have the smart key K, the intrusion of a suspicious person can be restricted. Moreover, since the door knob is not provided in the outdoor side surface of the emergency door 31, it is difficult to open | release the emergency door 31 so that it may pull to the near side from the outdoor side. Therefore, it is possible to further increase the deterrence against the suspicious person opening the emergency door 31. However, since the emergency door 31 is formed with a posting port 37, a resident or the like can easily open the emergency door 31 even from the outdoor side by placing a hand on the posting port 37.

  Since the load applied to the door main body 24 of the entrance door 18 is detected by the door load sensor 44, the emergency door 31 is prevented from being unlocked even though the entrance door 18 is openable. it can.

  In the entrance door 18, the door body 24 is easily deformed leaving a door frame 32 when a load is applied. Therefore, even if the building entrance 12 or the door frame 22 is deformed, the door frame 24 is deformed. 32 deformation can be suppressed. As a result, even if the entrance door 18 falls into a state where it cannot be opened, the emergency door 31 can be kept open.

(Other embodiments)
The present invention is not limited to the description of the above embodiment, and may be implemented as follows, for example.

  (1) In the entrance door 18, a door load sensor 44 may be provided so as to detect a load applied to the plate surface of the door handle 25 or the door body 24. For example, when the cylinder lock 26 of the front door 18 is in an unlocked state and the load applied to the door handle 25 or the door body 24 in the opening direction of the front door 18 is detected, the home server 41 If the load is larger than the reference value, the entrance door 18 is determined to be in a state where it cannot be opened. According to this configuration, a state in which excessive force is applied to the entrance door 18 when a person is trying to open the entrance door 18 can be specified as a state in which the entrance door 18 cannot be opened.

  Note that a sensor as a lock state detection unit that detects the lock state of the cylinder lock 26 may be provided on the entrance door 18. In this case, even when the cylinder lock 26 is not an electric locking device, when determining whether or not the entrance door 18 cannot be opened, the execution condition is that the cylinder lock 26 is in the unlocked state. can do.

  (2) The door body 24 may be provided with a plurality of door load sensors 44. For example, the home server 41 calculates the load applied to a plurality of portions of the door body 24 based on the detection signal of each door load sensor 44, and whether or not there is a bias in the magnitude of the calculated loads. If the calculated load is biased in size, it is determined that the entrance door 18 cannot be opened.

  (3) Deformation detecting means for detecting deformation of the door frame 22 may be provided in the door frame 22. For example, the deformation detection means may be a signal line arranged so as to extend along the door frame 22 so as to be cut along with the deformation of the door frame 22.

  (4) The entrance door 18 may be provided with a drive unit that forcibly opens and closes the emergency door 31 by driving. For example, the home server 41 has a configuration in which the emergency locking device 35 is shifted to the unlocked state and the drive unit is driven to open the emergency door 31. In this case, it is not necessary to open the emergency door 31 from the outdoor side so that the resident can easily pass through the emergency doorway 28.

  The door 18 may be provided with a door knob for the emergency door 31, and the door hinge 33 and the emergency locking device 35 may be exposed on the outdoor side surface of the emergency door 31.

  (5) The locking system may include an earthquake sensor that detects that an earthquake has occurred. In this case, the home server 41 can determine whether or not an earthquake has occurred based on the detection signal of the earthquake sensor.

  (6) In the unlocking permission determination for the emergency door 31, in addition to or instead of determining whether an earthquake has occurred, it is determined whether a fire has occurred, or the building 10 is in a flooded state. It may be determined whether or not there is. In short, it is only necessary to include a determination as to whether or not a disaster that could deform the building entrance 12 has occurred.

  The unlocking permission determination may include a determination as to whether or not a person is trying to open the emergency door 31. For example, a contact sensor that detects that a human hand touches the emergency door 31 is provided in the emergency door 31, and the home server 41 has a smart key K held by the person who touched the emergency door 31. If it does, it will be set as the structure which permits the unlocking of the emergency door 31. FIG. In this case, inconvenience can be avoided if the emergency door 31 is unlocked even though the person in the building 10 intends not to go outside.

  (7) As an authentication process performed when unlocking the entrance door 18 or the emergency door 31, in addition to the process of verifying authentication information, a process of verifying a person's fingerprint, a process of verifying a personal identification number, etc. It is done. Unlike the authentication process performed by the unlocking signal of the smart key K, these processes are effective as an authentication process in the event of an earthquake that occurs unexpectedly because the residents do not need to possess the smart key K. Is.

  (8) When the magnitude of the earthquake acquired from the earthquake information is larger than the reference scale, the home server 41 solves the emergency door 31 without determining whether or not the entrance door 18 is in a state where it cannot be opened. A lock process may be performed.

  (9) In the entrance door 18, the emergency door 31 may be a sliding door that is slidable, a detachable surface grid, or the like, instead of a hinged door that can rotate with respect to the door body 24. The point is that the emergency doorway 28 of the door body 24 may be opened and closed by the emergency door 31.
