Description

Technical Field

[0001] The present invention relates to a door, a blind system, and a luggage delivery system.

Background Art

[0002] In recent years, the demand for home delivery and delivery has been increasing, and not only receiving packages in person but also receiving them at receiving facilities such as home delivery boxes and home delivery lockers is often selected by users. In addition, there is also an increasing demand for a receiving method called "leave-and-deliver," in which a user designates a place where a third party including a package delivery person can freely access and the package is delivered to that place. It goes without saying that receiving packages through receiving facilities or leave-and-deliver is convenient for users, but it is also highly convenient and useful for delivery companies as it can reduce the number of redeliveries.

Summary of the Invention

Problems to be Solved by the Invention

[0004] However, if there are no available slots in the delivery locker when the delivery person arrives with a package, or if the package cannot be left unattended, the package may have to be received in person. However, there are times when people do not want to meet the delivery person face-to-face, or for security reasons, they do not want the delivery person to enter their home even if they meet face-to-face. There are also requests to prevent the delivery person from seeing inside the house, rather than meeting face-to-face. Furthermore, there are situations where people cannot go to the door to receive a package even if they want to, such as when they are getting dressed or cannot leave their child's side, and there has been a request to be able to receive packages directly from the delivery person who comes to deliver them, even in such situations.

[0005] This invention has been made in view of the above circumstances, and its purpose is to enable direct handover of packages with delivery personnel who come to deliver or collect them, while reducing stress during the handover of packages. [Means for solving the problem]

[0006] The invention described in claim 1 is, for example, as shown in Figures 1 to 14, a vertically separated door 3 (front door 3) for opening and closing an opening 2a (front door 2a) formed in the exterior wall 2 of a building, The upper door 4 (first door 4) located on the upper side, The lower door 5 (second door 5) is located directly below the upper door 4, A connecting means 7 for connecting or disconnecting the upper door 4 and the lower door 5, A first locking device that can lock or unlock the lock on the upper door 4 when the opening 2a is closed, The device is characterized by comprising a second locking device that allows locking or unlocking of the lock on the lower door 5 when the opening 2a is closed.

[0007] According to the invention described in claim 1, by locking the first locking device, unlocking the second locking device, and further releasing the connection between the upper door 4 and the lower door 5 by the connecting means 7, only the lower door 5 can be opened and closed. Therefore, by opening only the lower part of the opening 2a formed in the outer wall 2, the delivery person D who has come to deliver or collect the package P can directly exchange the package P with the delivery person P. Furthermore, by opening only the lower part of the opening 2a in this way when exchanging the package P, the user U and the delivery person D do not have to see each other's faces, thus reducing stress during the exchange of the package P. Furthermore, by connecting the upper door 4 and the lower door 5 with the connecting means 7, the upper door 4 and the lower door 5 can be treated as a single door, thus not obstructing the passage of people through the opening 2a.

[0008] The invention described in claim 2 is, for example, as shown in Figure 4, in the door 3 described in claim 1, A control device 8 is connected to the connecting means 7, the first locking device and the second locking device in a communication manner, and controls the operation of the connecting means 7, the operation of the first locking device and the operation of the second locking device. The device is characterized by being communicatively connected to the control device 8 and comprising door designation means for designating the upper door 4 and the lower door 5 to be operated.

[0009] According to the invention described in claim 2, the door designation means, which is communicatively connected to the control device 8, allows the user to specify and operate the door 4 or 5 to be operated from among the upper door 4 and the lower door 5. This eliminates the need to manually operate the connecting means 7, the first locking device, and the second locking device each time. This reduces stress during the handover of luggage P.

[0010] The invention described in claim 3 is, for example, as shown in Figure 4, in the door 3 described in claim 2, The door selection means is characterized by being an operation button device 9 equipped with a plurality of buttons 9a, 9b for manually selecting the doors 4 and 5 to be operated.

[0011] According to the invention described in claim 3, the door selection means is an operation button device 9 equipped with a plurality of buttons 9a, 9b for manually selecting the doors 4, 5 to be operated. Therefore, the user U can easily operate the door by simply pressing the buttons on the operation button device 9. This reduces stress when handing over luggage P.

[0012] The invention described in claim 4 is, in the door 3 described in claim 2, The system is equipped with a means for acquiring package information to obtain in advance information on the external dimensions or weight of the package P to be delivered. The door designation means is characterized by designating the upper door 4 and the lower door 5 to be operated based on the external dimensions or weight information of the luggage P.

[0013] According to the invention described in claim 4, the door designation means designates the door 4 or 5 to be operated from the upper door 4 and the lower door 5 based on the external dimensions or weight information of the luggage P acquired in advance by the luggage information acquisition means. Therefore, when the luggage P is handed over, the optimal door 4 or 5 corresponding to the external dimensions or weight information of the luggage P is selected and operated. This prevents the luggage P from being handed over in an unnatural posture, thereby reducing the burden during the handover of the luggage P, and consequently reducing stress during the handover of the luggage P.

[0014] The invention described in claim 5 is a blindfold system, as shown in Figure 8, for example, A building having the door 3 described in claim 1 as the entrance door 3 has an entrance 1, The aforementioned entrance 1 is equipped with an aerial image display device 20 for displaying aerial images 20a by projecting them into the space of the entrance 1. The aerial image display device 20 is configured to display the aerial image 20a when the upper door 4 is opened while the lower door 5 is closed.

[0015] According to the invention described in claim 5, the aerial image display device 20 installed in the entrance 1 is set to display an aerial image 20a when the upper door 4 is opened while the lower door 5 is closed. For example, when the upper door 4 is opened to hand over a package P, the aerial image 20a appears to float and is displayed in the space of the entrance 1. As a result, the aerial image 20a acts as a screen, shielding the space beyond the entrance 1 and blocking the view of the delivery person D, thus reducing the stress of feeling like the inside of the room is being seen when handing over a package P.

[0016] The invention described in claim 6 is a luggage delivery system P, as shown in Figures 9 to 14, for example. The door 3 described in claim 1, The system includes transportable mobile units 25, 26, and 45 that are configured to autonomously travel on the floor of the room 1 (entrance 1) inside the building where the door 3 is provided. The transporting bodies 25, 26, and 45 are characterized in that they are set to approach very close to the opening 2a when the luggage P is being handed over.

[0017] According to the invention described in claim 6, the transport mobile units 25, 26, and 45, which are set to autonomously travel on the floor of room 1, are set to approach very close to the opening 2a when handing over the package P. As a result, the transport mobile units 25, 26, and 45 act as obstacles, preventing people or animals from entering through the opening 2a. This makes it possible to hand over the package P using the autonomously travelable transport mobile units 25, 26, and 45, even if, for example, user U, who is a resident, is unable to go to room 1. In other words, delivery person D can hand over the package P directly, and user U will feel less stressed by the situation of being at home but unable to go to room 1.

[0018] The invention according to claim 7 is, for example, as shown in FIGS. 9 to 13, in the luggage delivery system of the luggage P according to claim 6, the room 1 is an entrance 1, and the entrance 1 includes an entrance dirt floor 1a and an entrance hall 1b set on a floor surface one step higher than the entrance dirt floor 1a. As the transport mobile bodies 25 and 26, a first transport mobile body 25 set to be able to autonomously travel within the entrance dirt floor 1a, and a second transport mobile body 26 set to be able to autonomously travel within the entrance hall 1b are deployed. The first transport mobile body 25 is set to a height substantially equal to the height from the entrance dirt floor 1a to the floor surface of the entrance hall 1b, and the upper surface thereof is a placement portion on which the luggage P or the second transport mobile body 26 is placed. The first transport mobile body 25 is set to approach close to the upper edge of the entrance hall 1b when placing the second transport mobile body 26 on the placement portion. The second transport mobile body 26 is set to move between the entrance hall 1b and the placement portion of the first transport mobile body 25 that has approached the upper edge.

[0019] According to the invention of claim 7, the luggage P placed in the entrance dirt floor 1a is received only by the first transport mobile body 25. When the luggage P is transported to the entrance hall 1b or the living room, the second transport mobile body 26 is placed on the upper surface of the placement portion of the first transport mobile body 25, and the luggage P is placed and transported on the upper surface of the placement portion of the second transport mobile body 26. Since the first transport mobile body 25 is set to a height substantially equal to the height from the entrance dirt floor 1a to the floor surface of the entrance hall 1b, the second transport mobile body 26 can move smoothly between the entrance hall 1b and the placement portion of the first transport mobile body 25 that has approached the upper edge.

Effect of the Invention

[0020] According to the present invention, it is possible to directly exchange packages with delivery personnel who come to deliver or collect them, while also reducing stress during the exchange of packages. [Brief explanation of the drawing]

[0022] Embodiments of the present invention will be described below with reference to the drawings. However, the embodiments described below are subject to various technically preferred limitations for carrying out the present invention, but the technical scope of the present invention is not limited to the embodiments and illustrated examples below. Note that the directions in the embodiments and illustrated examples below are set solely for the convenience of explanation.

[0023] Figure 1 is a front view showing the entrance door 3 installed at the entrance 1 of a user's house. The entrance 1 is separated from the outdoors by an exterior wall 2, and an entrance doorway 2a is formed in the exterior wall 2. The floor surface located on the indoor side of the exterior wall 2 is designated as the entrance floor 1a. The entrance door 3 in this embodiment opens and closes the entrance doorway 2a, and is a single-leaf door with a hinge 3a on the right side when viewed from the outside. The hinge 3a is attached to a door frame 3b which is fixed to the opening edge that constitutes the entrance doorway 2a.

[0024] As shown in Figures 1 to 4, the entrance door 3 of this embodiment is a vertically separated type, comprising a first door 4 located above and having a longer vertical dimension, and a second door 5 located below and having a shorter vertical dimension. The first door 4 and the second door 5 are each rotatably attached to the door frame 3b via a plurality of hinges 3a. In other words, the entrance door 3 is designed to rotate with the first door 4 and the second door 5 separated.

[0025] In this embodiment, as shown in Figure 3, only the second door 5 located below is configured to open and close (rotate) independently, while the first door 4 located above is configured not to open or close independently. However, this is not the only configuration, and the first door 4 may also be configured to open and close independently. In other words, in this embodiment, as shown in Figure 3, there are two opening and closing methods: either the lower second door 5 opens and closes independently, or the upper and lower first doors 4 and the second door 5 open and close simultaneously. Therefore, when a resident user U receives a package P from a delivery person D, they can receive the package P by opening only the second door 5, thus avoiding face-to-face contact with the delivery person D. Also, when entering or exiting through the front door 2a, the first door 4 and the second door 5 are opened and closed simultaneously.

[0026] The first door 4 is equipped with a push-pull type door handle 4a on the exterior side and a lever type door handle 4b on the interior side. The operating method of door handles 4a and 4b is merely an example and is not limited to the above. The operating methods of door handles 4a and 4b may be different for the exterior and interior as described above, or they may be the same for both.

[0027] Furthermore, the first door 4 is equipped with a locking device (first locking device) which, although not shown in the diagram, has a basic configuration including a latch bolt 4c, a deadbolt, a strike 4d, a cylinder, and a thumbturn. In other words, the latch bolt 4c can be operated by operating the door handles 4a and 4b, and the deadbolt can be operated by operating the cylinder or thumbturn.

[0028] The second door 5, like the first door 4, is equipped with a push-pull type door handle 5a on the exterior side and a lever type door handle 5b on the interior side. Furthermore, the second door 5 also has a locking device (second locking device) which, although not shown in part, has a basic configuration including a latch bolt 5c, deadbolt, strike 5d, cylinder, and thumbturn.

[0029] Furthermore, since having the first door 4 and the second door 5 constantly separated would hinder people from entering and exiting, these two doors are normally connected and function as a single entrance door 3. In other words, the entrance door 3 is further equipped with a connecting means 7 for connecting the first door 4 and the second door 5. This allows the first door 4 and the second door 5 to be opened and closed as a single unit.

[0030] The connecting means 7 includes a connecting deadbolt 7a and a strike 7b into which the connecting deadbolt 7a is inserted. As shown in Figure 4, the connecting deadbolt 7a is provided at the lower end of the first door 4 and is configured to move back and forth relative to the lower end surface of the first door 4. In other words, the connecting deadbolt 7a can protrude downward from the lower end surface of the first door 4 or retract from the lower end surface of the first door 4. Strike 7b is located at the upper end of the second door 5 and receives the connecting deadbolt 7a which is in a position protruding downward.

[0031] In this embodiment, a connecting deadbolt 7a is provided on the first door 4 side and a strike 7b is provided on the second door 5 side, but it is not limited to this and may be provided in the reverse order. That is, a strike 7b may be provided on the first door 4 side and a connecting deadbolt 7a may be provided on the second door 5 side.

[0032] In this embodiment, the connecting means 7 includes a connecting deadbolt 7a and a strike 7b, but it is not limited to this configuration. Other connecting means 7 may be provided, such as a locking device like a slide latch that spans the indoor side of the first door 4 and the indoor side of the second door 5, or an electromagnet that attaches to and detaches when energized, provided on the first door 4 side and / or the second door 5 side.

[0033] As shown in Figure 4, the locking devices and connecting means 7 in the first door 4 and the second door 5 are configured to be controllable by the control device 8. The control device 8 is comprised of a dedicated computer device installed in the user's home. However, it is not limited to this; a cloud computing system built on the internet may be used as the control device 8, or the PC or home server used by user U may be used as the control device 8. Alternatively, the control device 8 may be connected to the PC or home server used by user U in a way that allows communication.

[0034] The control device 8 of this embodiment, although not shown in the figures, includes a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), HDD (Hard Disk Drive), and a communication module.

[0035] The CPU executes various programs and performs calculations. ROM stores programs necessary for startup. RAM is a work area that temporarily stores CPU processing data and other information. HDD stores various data and programs. The communication module communicates with other devices via a communication network.

[0036] Furthermore, the locking devices on the first door 4 and the second door 5, and the connecting means 7 are connected to each other via a communication network. The control device 8, the locking devices on the first door 4 and the second door 5, the connecting means 7, and the communication network, along with the operation button device 9, constitute an entrance door control system.

[0037] The operation button device 9 is mounted on the indoor side of the entrance door 3 and is used by the user U to operate the first door 4 and the second door 5 when entering or exiting the entrance doorway 2a and when handing over luggage P. The operation button device 9 in this embodiment has a first button 9a for simultaneously operating the first door 4 and the second door 5, which are integrally connected by a connecting means 7, and a second button 9b for operating only the lower second door 5. In other words, the first button 9a and the second button 9b function as door selection means for specifying the door to be operated.

[0038] To explain in more detail, when the first button 9a is pressed, the connecting deadbolt 7a is first inserted into the strike 7b. This connects the first door 4 and the second door 5 as a single unit, allowing them to be opened and closed simultaneously. Furthermore, the door handles 5a and 5b on the second door 5 become inoperable, and simultaneously, the latch bolt 5c on the second door 5 also becomes inoperable. The state in which the door handles 5a and 5b are inoperable and the latch bolt 5c is also inoperable means either that the door handles 5a and 5b are fixed and cannot move, or that the linkage between the door handles 5a and 5b and the latch bolt 5c is released, so that even if the door handles 5a and 5b are moved, the latch bolt 5c cannot be operated. At this time, the latch bolt 5c is either not inserted into the strike 5d, or its operation is linked to that of the latch bolt 4c of the first locking device on the first door 4 by an interlocking mechanism (not shown). Furthermore, the deadbolt of the second door 5 is also assumed to be released. In other words, if the connecting deadbolt 7a is not inserted into the strike 7b, the second door 5 can be opened and closed freely. To put it another way, the second locking device of the second door 5 is unlocked, and the first door 4 and the second door 5 can be operated simultaneously by simply using the door handles 4a and 4b of the first door 4.

[0039] On the other hand, when the second button 9b is pressed, the connecting deadbolt 7a is disengaged from the strike 7b and retracted, the first locking device of the first door 4 becomes inoperable, and the second locking device of the second door 5 becomes operable. Figure 4 illustrates the state when the second button 9b is pressed. More specifically, when the second button 9b is pressed, the connecting deadbolt 7a disengages from the strike 7b and retracts. Furthermore, the door handles 4a and 4b on the first door 4 become inoperable, and simultaneously, the latch bolt 4c on the first door 4 also becomes inoperable. The state in which the door handles 4a and 4b are inoperable, and the latch bolt 4c is also inoperable, means either that the door handles 4a and 4b are fixed and cannot move, or that the linkage between the door handles 4a and 4b and the latch bolt 4c is released, so that the latch bolt 4c cannot be operated even if the door handles 4a and 4b are moved. In this embodiment, when the second button 9b is pressed and the connecting deadbolt 7a is disengaged from the strike 7b and retracted, the latch bolt 4c is inserted into the strike 4d, and the deadbolt is also inserted into the strike 4d, locking the first door 4. In other words, the first door 4 becomes unable to be opened or closed. Furthermore, the door handles 5a and 5b on the second door 5 become operable, and at the same time, the latch bolt 5c on the second door 5 also becomes operable. By turning the thumbturn on the second door 5, the latch bolt 5c can be released, and by operating the door handle 5b on the inside, the latch bolt 5c is activated and removed from the strike plate 5d. This allows the second door 5 to be opened, leaving only the lower part of the entrance doorway 2a open.

[0040] In this embodiment, the second button 9b is pressed by the user U's own fingers, but it may also be pressed electrically upon receiving an unlocking signal (second signal S2) from an external device. The external device can be anything that is connected to the control device 8 via a communication network and can communicate with it. Examples include the intercom 10 or in-home display 11 described later, a mobile information terminal such as a smartphone used by the user U, or a mobile transport device such as a luggage transport robot. In any case, the external device has a communication module for accessing the control device 8, and, if necessary, has downloaded the application program required for operating the second button 9b.

[0041] If the handover of package P is carried out by opening only the lower part of the entrance doorway 2a, the resident user U and the delivery person D will not have to see each other face to face. This is also advantageous from a security standpoint as it does not require opening the entire entrance doorway 2a. However, security can be further enhanced by verifying the identity of the delivery person D in advance.

[0042] Figure 5 shows an identity verification system for verifying the identity of delivery person D who comes to deliver package P directly to the user's home. By using such an identity verification system, user U can obtain the registered identification information 12a of delivery person D who came to deliver package P directly to user U, and verify the identity of delivery person D.

[0043] The identity verification system of this embodiment comprises at least an intercom 10, an in-home display 11, a delivery person information management database 12 built on the internet, and a communication network.

[0044] As shown in Figure 1, the intercom 10 is installed, for example, on the wall next to the front door 3, and is equipped with an authentication function for identity verification. As shown in Figure 5, such an intercom 10 includes a camera 10a, a chime button 10b, a communication unit 10c consisting of a microphone and speaker, a control unit (not shown), and a communication module (not shown).

[0045] Camera 10a is activated when the chime button 10b is pressed, and is capable of focusing on and taking pictures of the space in front of the front door 3. While the captured data is not automatically recorded, it can be recorded via operation from the in-house display 11. Camera 10a captures not only visitors but also delivery person D who has come to deliver package P directly. As mentioned above, delivery person D who has come to deliver package P directly requires identity verification and is therefore required to present authentication information. Authentication information could be biometric information such as the delivery person D's face and physique, an ID card carried by delivery person D, or a QR code displayed on the screen of the communication terminal of the delivery company to which delivery person D belongs. Alternatively, if the delivery person D's information is linked to the shipping label of package P being delivered, the shipping label of package P may also be used. The authentication information captured by camera 10a is converted into data (hereinafter referred to as authentication information data) and transmitted to the delivery person information management database 12. The authentication information data may also be recorded on a home server (not shown) installed in the user's home.

[0046] The chime button 10b is used to sound a chime, and when pressed, a chime sound is output from the in-home display 11. In addition, as described above, it is also used as the activation button for the camera 10a, and as described later, it is also used as the activation button for the communication unit 10c.

[0047] The communication unit 10c has a built-in microphone and speaker, enabling two-way communication with the communication unit 11c on the in-home display 11.

[0048] The control unit is comprised of a dedicated computer device, which, although not shown in the diagram, includes at least a CPU, RAM, and memory. The CPU executes various programs and performs calculations. RAM is a work area for temporarily storing processing performed by the CPU and for storing data. The memory stores various data and programs.

[0049] The communication module of the intercom 10, although not shown in the diagram, includes a first communication module for communicating with the in-home display 11 and a second communication module for communicating with the delivery person information management database 12. Both communication modules communicate with other devices via a communication network, but the first communication module is wired to the in-home display 11, and the second communication module is connected to the delivery person information management database 12 via the internet or the like. The first communication module is also assumed to be connected to the home server for communication.

[0050] The intercom 10 configured as described above has a registration identification information acquisition means as one of the software configurations that functions through the execution of multiple programs. This registration identification information acquisition means can transmit authentication information data captured by the camera 10a, along with a one-time password 10PW, to the delivery person information management database 12 via the second communication module and the communication network. The transmission of authentication information data may be performed automatically after the camera 10a takes a picture, or it may be performed by user U using the in-home display 11. In this embodiment, the transmission is performed automatically after the camera 10a takes a picture, and the authentication information is the face (biometric authentication) of delivery person D.

[0051] The in-home display 11, although not shown in the diagram, is installed, for example, on a wall inside the user's home and is connected to the intercom 10 via a communication network. Such an in-home display 11 includes a display screen 11a, various operation buttons 11b, a call unit 11c consisting of a microphone and speaker, a control unit (not shown), and a communication module (not shown). The in-home display 11 may also be a mobile communication device such as a smartphone or tablet used by user U.

[0052] Display screen 11a is for displaying images captured by camera 10a, and user U can view this display screen 11a to confirm the arrival of delivery person D. The images displayed on display screen 11a also include information that is recognized as authentication data.

[0053] The various operation buttons 11b consist of multiple operation buttons and are pressed when the user U wants to send authentication information data at any time as described above, when the user wants to record image data of the delivery person D who came to deliver the product directly to the home server, or when the user wants to activate the telephone unit 11c.

[0054] The communication unit 11c has a built-in microphone and speaker, enabling two-way communication with the communication unit 10c of the intercom 10.

[0055] The control unit is comprised of a dedicated computer device, which, although not shown in the diagram, includes at least a CPU, RAM, and memory. The CPU executes various programs and performs calculations. RAM is a work area for temporarily storing processing performed by the CPU and for storing data. The memory stores various data and programs.

[0056] The communication module of the in-home display 11 is connected to the intercom 10 via a wired connection, enabling communication. This communication module is also assumed to be connected to the home server.

[0057] The in-home display 11, configured as described above, has an interlocking mechanism that allows the functions of the intercom 10 to be used in conjunction with each other, as one of the software configurations that functions through the execution of multiple programs. In other words, in this embodiment, the in-home display 11 and the intercom 10 have a master unit and slave unit relationship, and the in-home display 11, which is the master unit, can perform all operations and settings of the intercom 10 from within the user's home. That is, the intercom 10 and the in-home display 11 may be treated together as a single intercom system.

[0058] The delivery driver information management database 12 is a database for managing information related to delivery driver D. This delivery driver information management database 12 may be managed by the delivery company to which delivery driver D belongs, or it may be jointly managed by multiple delivery companies. In this embodiment, it is a database jointly managed by multiple delivery companies, so that delivery driver D from any of the delivery companies can respond when they come directly to the user's home.

[0059] The delivery person information management database 12 compares the authentication information data transmitted from the intercom 10 with the delivery person information registered in this database 12 and extracts information (registration identification information data 12a) that matches the delivery person D who came to make the delivery directly. The extracted registration identification information data 12a is then transmitted to the intercom 10 via the communication network. The intercom 10 and the in-house display 11 which is linked to the intercom 10 can acquire the registration identification information data 12a and confirm it on the display screen 11a of the in-house display 11. If the registration identification data 12a cannot be confirmed at this point, it is advisable to perform authentication again, as the person standing in front of the front door 3 may not be included in the list of delivery personnel D registered in the delivery personnel information management database 12, or there may be an authentication error.

[0060] The identity verification system of this embodiment, configured as described above, is first activated when a delivery person D who has come to deliver the package directly to the front door 3 presses the chime button 10b on the intercom 10. That is, when the chime button 10b is pressed, the camera 10a and the communication unit 10c of the intercom 10 are activated, and furthermore, the display screen 11a of the in-house display 11 is activated.

[0061] Next, the camera 10a of the intercom 10 performs facial recognition of the delivery person D. Once facial recognition is performed, the recognition information data is transmitted to the delivery person information management database 12 via the first communication module, the communication module, and the communication network.

[0062] In the delivery person information management database 12, the authentication information data transmitted from the intercom 10 is compared with the delivery person information of the registered delivery person D, and the registration identification information data 12a that matches the delivery person D who came to make the delivery is extracted. The extracted registration identification information data 12a is then transmitted to the intercom 10 via the communication network.

[0063] The registration identification data 12a can be received through the communication module of the intercom 10, and the received registration identification data 12a can be viewed on the display screen 11a of the in-home display 11. In this way, it is possible to verify the identity of delivery person D who came to deliver the package directly.

[0064] Then, if user U checks the registered identification information data 12a and determines that there is no problem, they press the second button 9b on the operation button device 9 of the front door 3 to make only the second door 5 open and close, and open only the lower part of the front door entrance 2a to receive the package P. This allows the package P to be handed over without having to meet the delivery person D who has come to deliver it face to face. On the other hand, if a problem is determined, user U will not only refrain from pressing the buttons 9a and 9b on the operation button device 9 of the front door 3, but may also press the notification button provided on the various operation buttons 11b of the in-house display 11.

[0065] The communication network in this embodiment may include various communication network types such as telephone lines, ISDN lines, optical fibers, mobile communication networks, satellite communication lines, CATV lines, and other dedicated lines, as well as Internet service providers (i.e., the Internet) that connect them. It may also be a collective communication network in which various communication networks such as LAN (Local Area Network), WAN (Wide Area Network), WiFi (Wireless Fidelity), Bluetooth®, and NFC (Near Field Communication) are connected in a manner that enables communication with each other. Furthermore, the connection method may be wired, wireless, or a mixture of wired and wireless.

[0066] Furthermore, in this embodiment, the handover of a package P with the delivery person D refers to the case where user U receives a delivered package P from delivery person D, and the case where delivery person D receives a package P to be collected from user U. Moreover, the type of package P is not limited to ordinary courier services, but can include a variety of items such as food and meals delivered by food delivery services, or clothing transported by dry cleaning services.

[0067] This embodiment provides the following excellent effects. In other words, by locking the first locking device, unlocking the second locking device, and further releasing the connection between the first door 4 and the second door 5 by the connecting means 7, only the second door 5 can be opened and closed. Therefore, by opening only the lower part of the entrance doorway 2a formed in the exterior wall 2, the delivery person D who has come to deliver or collect the package P can directly exchange the package P with the user U. Furthermore, by opening only the lower part of the entrance doorway 2a in this way, the user U and the delivery person D do not have to see each other's faces, thus reducing stress during the exchange of the package P. Furthermore, by connecting the first door 4 and the second door 5 with the connecting means 7, the first door 4 and the second door 5 can be treated as a single door, thus not obstructing the entry and exit of people through the entrance 2a. Furthermore, even if only the first door 4 is opened and only the top of the entrance 2a is left open, delivery person D cannot easily step into the entrance 1. This can reduce stress for user U, who finds it stressful to have people enter their home.

[0068] Furthermore, since the door designation means, which is communicatively connected to the control device 8, allows the user to specify and operate the doors 4 and 5 to be operated from among the first door 4 and the second door 5, the effort of manually operating the coupling means 7, the first locking device, and the second locking device each time is eliminated. This reduces stress during the handover of luggage P.

[0069] Furthermore, since the door selection means is an operation button device 9 equipped with multiple buttons 9a, 9b for manually selecting the doors 4 and 5 to be operated, the user U can easily operate the system by simply pressing the buttons on the operation button device 9 to select doors 4 and 5. This helps to reduce stress during the handover of luggage P.

[0070] Furthermore, there is a growing demand for the realization of a decarbonized society through the promotion of carbon neutrality, which aims to achieve virtually zero carbon dioxide emissions, and for the achievement of the Sustainable Development Goals (SDGs). Various initiatives are underway in the construction industry. The vertically separated entrance door 3 in this embodiment can be introduced as a renovation product for outdoor-facing doors in existing houses. Therefore, it can promote home renovations and reduce the generation of unnecessary waste materials. In addition, by renovating a house, it becomes possible to continue living in it. Thus, it can contribute to the realization of a decarbonized society through the promotion of carbon neutrality and the achievement of the SDGs.

[0071] [Variation] The embodiments to which the present invention can be applied are not limited to those described above, and can be modified as appropriate without departing from the spirit of the invention. Modifications are described below. The following modifications may be combined as much as possible. Furthermore, in each of the following modifications, elements common to the above-described embodiments are denoted by the same reference numerals, and their descriptions are omitted or simplified.

[0072] [Variation 1] Figure 6 shows a modified example of the entrance door 3A, which is a vertically separated type divided into three parts: a first door 4 located at the top and having a long vertical dimension, a second door 5 located at the bottom and having a shorter vertical dimension, and a third door 6 located between the first door 4 and the second door 5. The first door 4, the second door 5, and the third door 6 are each rotatably attached to the door frame 3b via a plurality of hinges 3a. In other words, the entrance door 3A is designed to rotate with the first door 4, the second door 5, and the third door 6 separated.

[0073] In this modified example, as shown in Figure 6, the entrance door 3A has a second door 5 located at the bottom and a third door 6 located in the center that open and close (rotate) independently, while the first door 4 located at the top is not set to open or close independently. However, this is not the only option, and the first door 4 may be set to open and close independently. In other words, in this modified example, there are two opening and closing methods: either the second door 5 located at the bottom opens and closes independently, or the third door 6 located in the center opens and closes independently, or all three doors 4, 5, and 6 open and close simultaneously. Therefore, when a resident user U receives a package P from a delivery person D, they can open either the second door 5 or the third door 6 to receive the package P, thus avoiding face-to-face contact with the delivery person D. Furthermore, when entering or exiting through the front door 2a, the first door 4, the second door 5, and the third door 6 are opened and closed simultaneously.

[0074] Since the first door 4 and the second door 5 are configured in the same manner as in the above embodiment, a description of their basic components will be omitted. The third door 6, like the first door 4 and the second door 5, is equipped with a push-pull type door handle (not shown) on the exterior side and a lever type door handle 6b on the interior side. The third door 6 is also equipped with a locking device (third locking device) having a basic configuration including a latch bolt, deadbolt, strike, cylinder, and thumbturn.

[0075] Furthermore, the entrance door 3A is equipped with multiple connecting means 7. The connecting means 7 includes a first connecting means 7 for connecting the first door 4 and the third door 6, and a second connecting means 7 for connecting the second door 5 and the third door 6. These first and second connecting means 7 each include a connecting deadbolt 7a and a strike 7b into which the connecting deadbolt 7a is inserted.

[0076] Furthermore, the locking devices on the first door 4, the second door 5, and the third door 6, as well as the first connecting means 7 and the second connecting means 7, are configured to be controllable by the control device 8. The control device 8 consists of a dedicated computer device installed in the user's home. The first and second connecting means 7 are capable of simultaneous control and individual control.

[0077] With the entrance door 3A configured as described above, which has a third door 6 in the center, the package P can be handed over through the third door 6. Unlike when the second door 5 located below is opened and only the lower part of the entrance door 2a is opened to hand over the package P, the package P can be handed over in a comfortable posture without bending over. Moreover, since the first door 4 is not opened, the package P can be handed over without making eye contact with the delivery person D. Furthermore, while the package P is being handed over with the third door 6 open, not only the first door 4 but also the second door 5 is not opened, so the clothes being worn are less likely to be seen by the delivery person D, thus reducing stress during the handover of the package P.

[0078] [Variation 2] Within the grounds of the user's house, there is a passageway for people to pass through, such as an entrance approach, and a gate 16 is provided on such a passageway as an entrance for people to enter and exit. The gate 16 is formed between one gatepost 17 and the other gatepost 18, and the gate 16 is opened and closed by a gate door 13. Figure 7 shows the gate 16 with a gate door 13 installed to open and close the gate 16.

[0079] In this modified example, the gateposts 17 and 18 are integrated with a wall 19 that blocks views from outside the property and prevents intrusion by suspicious individuals. Furthermore, one of the gateposts 17 is equipped with an intercom 10 with the same configuration as in the above embodiment, which is connected to the in-house display 11 and also connected to the delivery person information management database 12, thereby establishing an identity verification system.

[0080] The gate door 13 that opens and closes the gate 16 is a single-leaf door with a hinge 18b on the right side when viewed from outside the property. The hinge 18b is attached to a hinge frame 18a fixed to the side of the right gate post 18.

[0081] The gate 13 in this modified example is a vertically separated type, comprising a first gate 14 located above and having a longer vertical dimension, and a second gate 15 located below and having a shorter vertical dimension. The first gate 14 and the second gate 15 are each rotatably attached to the hinge frame 18a via a plurality of hinges 18b. In other words, the gate 13 is designed to rotate while the first gate 14 and the second gate 15 are separated.

[0082] In this embodiment, only the second gate 15 located below is configured to open and close (rotate) independently, while the first gate 14 located above is configured not to open or close independently. However, this is not the only configuration, and the first gate 14 may also be configured to open and close independently. In other words, in this embodiment, there are two opening and closing methods: either the lower second gate 15 opens and closes independently, or the upper and lower first gates 14 and the second gate 15 open and close simultaneously. Therefore, when a resident user U receives a package P from a delivery person D, they can receive the package P by opening only the second gate 15, thus avoiding face-to-face contact with the delivery person D. Furthermore, when entering or exiting through the gate 16, the first gate 14 and the second gate 15 are opened and closed simultaneously.

[0083] The first gate 14 and the second gate 15 are equipped with lever-type door handles 14a and 15a on both the outside of the property and the inside of the building. The operating method of the door handles 14a and 15a is merely an example and is not limited to the above. Furthermore, the first gate 14 and the second gate 15 are equipped with a locking device having a basic configuration such as a latch bolt, deadbolt, strike, cylinder, and thumbturn. Although not shown in the figures, such a locking device is assumed to be installed using the door frame 17a provided on the side of the left gate post 17.

[0084] Furthermore, since the first gate 14 and the second gate 15 would hinder people from entering and exiting if they were always separated, these two gates are normally connected and function as a single gate 13. In other words, the gate 13 is further equipped with a connecting means 7 for connecting the first gate 14 and the second gate 15. This allows the first gate 14 and the second gate 15 to be opened and closed as a single unit.

[0085] The locking devices and connecting means 7 in the first gate 14 and second gate 15 described above are configured to be controllable by the control device 8. The gate 13 can then be controlled by this control device 8 and a gate control system that includes the locking devices, connecting means 7, communication network, and operation button device 9 in the first gate 14 and second gate 15. The control logic is the same as that of the entrance door control system in the above embodiment and will not be explained further.

[0086] According to this modified version, when handing over a package P in the area of ​​the site where the user's house is built, specifically in the area with a gate 16 and gate 13, the second gate 15 located below can be opened, and only the lower part of gate 16 can be opened to hand over the package P. As a result, the first gate 14 located above does not need to be opened, allowing the handover of the package P to be done without the user having to make direct eye contact with the delivery person D who has come to deliver the package, thereby reducing stress during the handover of the package P.

[0087] [Variation 3] In the above embodiment, the entrance door 3 is configured such that only the second door 5 located below it can be opened and closed independently, while the first door 4 located above it cannot be opened and closed independently. However, in this modified example, the entrance door 3 is configured so that the first door 4 located above it can also be opened and closed independently. In other words, in this modified example, as shown in Figure 8, there are three opening and closing patterns: either only the upper first door 4 opens and closes independently, only the lower second door 5 opens and closes independently, or both the upper and lower first door 4 and second door 5 open and close simultaneously.

[0088] When the first door 4 and the second door 5 are opened and closed independently, or when the first door 4 and the second door 5 are opened and closed simultaneously, the buttons 9a and 9b of the operation button device 9 are pressed to select which door can be opened or closed. In the above embodiment, the first door 4, which is located above, was set not to be opened or closed independently, but in this modified example, the first door 4 is set to be opened and closed independently. Therefore, the operation button device 9 further includes a first button 9a, a second button 9b, and a third button (not shown) for selecting the first door 4, which is located above. In other words, by pressing the third button, only the first door 4 can be opened and closed independently, allowing only the upper part of the entrance 2a to be opened for the handover of luggage P.

[0089] Furthermore, while user U may specify which door to open as described above, if the external dimensions and weight information of the package P to be delivered are obtained and known in advance, the system may be configured to automatically select the door to open according to that information. In this case, the in-home display 11 (including the user U's communication information terminal) has a door selection means (door selection program) as a function including software or application that specifies the optimal door based on the external size information and weight information of the package P. The in-home display 11 also receives the external size information and weight information of the package P as advance information from the delivery company that will deliver the package P. Therefore, the in-home display 11 executes the door selection program and, based on the advance information sent from the delivery company, pre-selects the door that will open when the package P is delivered. Then, when the camera 10a of the intercom 10 reads the information of the package P, it compares the read information with the advance information, and if the information matches, it opens only the door that was registered in advance, allowing the package P to be handed over.

[0090] By the way, when opening the first door 4 to hand over luggage P, the handover of luggage P is easy, but it is possible to see from the outside of the front door 3 all the way to the back of the entrance 1. Therefore, in this modified example, a means of concealment (concealment system) using aerial display technology is provided. The blindfolding mechanism in this modified example comprises an aerial image display device 20 and a remote control 21.

[0091] The aerial image display device 20, although not shown in the diagram, is an optical system consisting of a light source (display), a retroreflective material, and a beam splitter. The light source and retroreflective material are housed within a casing, and the beam splitter forms part of the casing. Light emitted from the light source undergoes normal reflection at the beam splitter and proceeds to the retroreflective material, where it is retroreflective in the same direction as the incident light and proceeds back to the beam splitter. The light that has passed through the beam splitter converges and then diffuses again, thereby enabling the display of an image in the air. The aerial image 20a displayed by this aerial image display device 20 is projected onto the entrance hall 1b of the entrance 1.

[0092] Furthermore, the aerial image display device 20 has a spatial touch sensor function, enabling touch operation on the aerial image 20a at the position where the aerial image 20a is floating.

[0093] The remote control 21 is used to activate the aerial image display device 20 and display the aerial image 20a, and in this modified example, it is installed on the wall of the entrance 1. Therefore, the remote control 21 can be operated to activate the aerial image display device 20 before opening the first door 4. However, this is not limited to the above. When the third button of the operation button device 9 is pressed, or when the first door 4 is opened and the luggage P is handed over based on the external dimensions and weight information of the luggage P that has been acquired in advance, the aerial image display device 20 may be configured to automatically display the aerial image 20a without the user U having to operate the remote control 21.

[0094] The aerial image 20a displayed by the aerial image display device 20 only needs to obstruct the view of the delivery person D, and its content is not particularly limited. The aerial image 20a provides a visual obscuration effect, but not a physical shielding effect. Therefore, while user U shown in Figure 8 is naturally visible to delivery person D, other users U1, who are residents, are obscured by the aerial image 20a and are either invisible or difficult to see. Also, the dog Dg shown in Figure 8 is straddling the aerial image 20a.

[0095] Furthermore, the aerial image display device 20a may include not only a blindfolding function but also an information display function for user U. That is, when activating the aerial image display device 20, the user can select between blindfolding mode and information display mode. In information display mode, for example, the time, weather information, inventory management information, user U's daily schedule, etc., can be displayed.

[0096] According to this modified example, with the entrance door 3 configured as described above, the package P can be handed over through the first door 4. Unlike the case where the second door 5 located below is opened and only the lower part of the entrance 2a is opened to hand over the package P, the package P can be handed over in a comfortable posture without bending over. Moreover, the privacy screen can block the delivery person D's line of sight, thus reducing the stress of the user feeling like their home is being seen when handing over the package P.

[0097] Furthermore, when keeping pets such as dogs (Dg) indoors, it is preferable to close the second door (5) located at the bottom and open the first door (4) located at the top to allow for the exchange of luggage (P), thereby preventing the pet from escaping outdoors.

[0098] [Variation 4] Figures 9 to 13 show modified examples where the delivery of cargo P is performed by transporting mobile units 25 and 26. The transporting mobile units 25 and 26 consist of a first transporting mobile unit 25 that moves across the entrance floor 1a and a second transporting mobile unit 26 that moves across the entrance hall 1b, which has a floor level one step higher than the entrance floor 1a.

[0099] The first transport mobile body 25 and the second transport mobile body 26 are both unmanned mobile bodies that travel on the floor. Therefore, they are equipped with multiple wheels, a mounting section which is a vehicle body on which the multiple wheels are rotatably mounted, a drive unit which rotates the multiple wheels, a movement control unit which controls the direction of movement of the transport mobile bodies 25 and 26, and sensors which are necessary for determining their own position. Furthermore, the first transport mobile unit 25 and the second transport mobile unit 26 are connected to each other via wireless communication, allowing them to accurately determine each other's positions.

[0100] The movement control unit consists of a microcomputer including a CPU, ROM, RAM, etc. The movement control unit controls automatic driving by loading a program pre-stored in ROM into RAM, executing it with the CPU, and controlling the movement of multiple wheels. The movement control unit may also consist of multiple electronic control units. These movement control units and drive units are built into the mounting section, which is the vehicle body. In other words, the first transport mobile unit 25 and the second transport mobile unit 26 are autonomous mobile cargo transport robots.

[0101] In this modified example, the second transportable mobile body 26 or the cargo P is placed on the upper surface of the mounting section of the first transportable mobile body 25. Also, the cargo P is placed on the upper surface of the mounting section of the second transportable mobile body 26. In other words, with respect to luggage P that is to be left in the entrance hall 1a, the first transport mobile body 25 waits in the entrance hall 1a with the luggage P placed on the upper surface of the loading area of ​​the first transport mobile body 25. In the case of luggage P that is to be carried from the entrance 1 into the living room, the second transport mobile body 26 is placed on the upper surface of the loading area of ​​the first transport mobile body 25, and the luggage P that is to be carried into the living room is placed on the upper surface of the loading area of ​​the second transport mobile body 26.

[0102] In order to enable the transport of luggage P into the living space by the second transport mobile body 26, the height of the upper surface of the mounting section of the first transport mobile body 25 is set to be approximately equal to the height of the floor in the entrance hall 1b. Furthermore, the first transport mobile body 25 senses the position of the entrance step in the entrance hall 1b using a sensor, and the movement control unit controls the movement of the first transport mobile body 25 based on the sensing result, so that it can move to a position close to the entrance step.

[0103] The first transport mobile unit 25 is normally kept in a waiting space 1c located in a corner of the entrance 1, as shown in Figures 12 and 13. The waiting space 1c is equipped with power supply equipment (not shown) to supply power to the first transport mobile unit 25. The waiting space 1c should preferably utilize dead space, such as the area below a shoe closet.

[0104] When receiving a package P via the first transport unit 25 and the second transport unit 26, first, the delivery person D presses the chime button 10b, and user U confirms the arrival of delivery person D. If user U is unable to go out to the front door 1, user U presses one of the various operation buttons 11b on the in-house display 11 to start the handover of package P by the second transport unit 26, thereby initiating the handover of package P.

[0105] Then, the second transport mobile unit 26, which was waiting in a waiting space (not shown) on the living room side, is activated and moves to the entrance 1. Once it reaches the entrance 1, the second transport mobile unit 26 communicates with the first transport mobile unit 25, as shown in Figure 12. At this time, the second transport mobile unit 26 transmits a signal (first signal S1) to the first transport mobile unit 25 to call the first transport mobile unit 25 to the vicinity of the entrance step. Upon receiving the first signal S1, the first transporter mobile body 25 moves to a position close to the entrance step, as shown in Figures 9 and 12, while performing sensing with its sensors.

[0106] Once the second transporter 26 confirms that the first transporter 25 has moved to the immediate vicinity of the entrance step, it moves from the entrance hall 1b to the upper surface of the mounting section on the first transporter 25, as shown in Figure 9, while performing sensing with its sensors.

[0107] Then, the first transport unit 25 moves toward the entrance door 3 while placing the second transport unit 26 on the upper surface of the mounting section. At this time, the first transport unit 25 moves based on control from the movement control unit, while determining its own position using sensors.

[0108] Furthermore, at this time, as shown in Figure 13 (and Figure 4), the second transport mobile body 26, while resting on the upper surface of the mounting section of the first transport mobile body 25, transmits a signal (second signal S2) to the control device 8 in the entrance door control system to open the second door 5. As a result, the first transport mobile body 25 and the second transport mobile body 26 can automatically open the second door 5, even if there is no user U nearby, and open only the lower part of the entrance doorway 2a.

[0109] When the second door 5 in the front door 3 is opened, and only the lower part of the entrance 2a is open, the delivery person D places the package P on the upper surface of the loading area of ​​the second transport mobile body 26, as shown in Figure 10. Here, the entrance door control system and the movement control units of the first transport mobile body 25 and the second transport mobile body 26 may be linked. That is, the first transport mobile body 25 and the second transport mobile body 26 may be controlled to move as close to the entrance door 2a as possible before receiving the package P, and then not start moving until the second door 5 is completely closed by the delivery person D. As a result, as long as the second door 5 is not completely closed, the first transport mobile body 25 and the second transport mobile body 26 with the package P loaded on them will be in a waiting state in front of the entrance door 2a, making it difficult for people or animals to enter from the bottom of the entrance door 2a that is not completely closed. Although not shown in the diagram, the second transport unit 26 or the first transport unit 25 receives a signal from the control device 8 to detect the closed state of the second door 5. Once the closed state of the second door 5 is confirmed, the second transport unit 26 or the first transport unit 25 transmits a signal (lock signal) to lock the locking device of the second door 5, thereby locking the second door 5.

[0110] As shown in Figure 11, the first transport mobile body 25 and the second transport mobile body 26, having received the luggage P, move to the immediate vicinity of the entrance step. Once it is confirmed that the first transport mobile body 25 has moved to the immediate vicinity of the entrance step, only the second transport mobile body 26, with the luggage P placed on the upper surface of its loading area, can transfer from the upper surface of the loading area on the first transport mobile body 25 onto the entrance hall 1b and transport the luggage P into the living room.

[0111] According to this modified version, even if user U, who is a resident, is unable to go out to the front door 1, the delivery of package P can be made using only the first transport unit 25, or by using both the first transport unit 25 and the second transport unit 26. In other words, delivery person D can directly deliver and receive package P, and user U will feel less stressed about being at home but unable to go out to the front door 1. To put it another way, it is possible to directly deliver or collect package P with delivery person D while reducing stress during the delivery of package P.

[0112] Furthermore, the in-home display 11 may allow input of the delivery schedule for the package P. If the schedule is determined in advance, once the identity verification of the delivery person D is complete, the delivery of the package P by the transport mobile units 25 and 26 can be performed automatically without having to press the button on the in-home display 11 to start the delivery of the package P by the second transport mobile unit 26.

[0113] [Variation 5] Figure 14 shows a modified example in which an opening 34a is provided elsewhere in the user's home 30 for the delivery and receipt of packages P. In this modified example, the user's home 30 is a detached house, and this user's home 30 has a low-ceiling storage room 40 with a ceiling height set to 0.8m to 1.4m. The opening 34a is formed in the exterior wall 34 that constitutes this low-ceiling storage room 40.

[0114] The low-ceiling storage room 40 refers to the space between the intermediate floor 32, which is built on a portion of the first-floor floor 31, and the first-floor floor 31, and is located adjacent to the first-floor living room 41. An intermediate-floor room 42, which is an intermediate-floor room, is located on the intermediate floor 32, and a second-floor living room 43, adjacent to the intermediate-floor room 42, is located above the first-floor living room 41.

[0115] Furthermore, the ceiling height of the low-ceiling storage room 4 can be adjusted as needed within the range of 0.8m to 1.4m. This ceiling height range of 0.8m to 1.4m is the minimum height required to allow a person to enter the low-ceiling storage room 4 and perform some work, and by keeping the ceiling height to the absolute minimum, the impact on adjacent buildings, such as reduced sunlight, caused by the increased height of the user's house 30 can be minimized.

[0116] The low-ceiling storage room 40 and the first-floor living room 41 are separated by a partition wall 36, and an entrance 36a is formed in the partition wall 36. The entrance 36a can be opened and closed by an interior door 37, and the interior door 37 can be locked.

[0117] Furthermore, the opening 34a formed in the exterior wall 34 can be opened and closed by an outdoor door 35. The low-ceiling storage room 40 is located on the first floor and is adjacent to the outdoor space, making it suitable for storing items used outdoors, for example. Furthermore, in this modified example, the low-ceiling storage room 40 is also used as a space for transferring luggage P, and the opening 34a serves as the transfer point for luggage P.

[0118] Furthermore, the outdoor door 35 of this modified example is a vertically separated type, comprising a first door 35a located above and having a longer vertical dimension, and a second door 35b located below and having a shorter vertical dimension. The first door 35a and the second door 35b are each rotatably attached to the door frame via a plurality of hinges. In other words, the outdoor door 35 is designed to rotate with the first door 35a and the second door 35b separated.

[0119] The operation and control of the outdoor doors 35 (first door 35a and second door 35b) in this modified example are the same as or similar to the operation and control of the entrance doors 3 (first door 4 and second door 5) in the above embodiment, so a description is omitted. Furthermore, in this modified example, a third transportable mobile body 45 is installed in the low-ceiling storage room 40. The operation and control of this third transportable mobile body 45 are the same as or similar to those of the first transportable mobile body 25 in the modified example described above, so a description is omitted. In other words, the delivery person D can hand over the package P not through the entrance 1 used by the resident user U, but through the opening 34a on the side of the low-ceiling storage room 40 where the goods are stored.

[0120] Since the outdoor door 35 faces the outside, it is naturally equipped with a locking device, and as mentioned above, the indoor door 37 can also be locked. Therefore, the low-ceiling storage room 40 is a highly secure space. In other words, even if a person or animal were to enter the low-ceiling storage room 40 through the opening 34a, the entrance 36a is blocked by the indoor door 37, thus preventing entry into the first-floor living room 41. Furthermore, in this modified example, the third transport mobile body 45 has a shielding plate 45a erected at the end facing the entrance 36a when the luggage P is being handed over, which can block the line of sight and deter people from entering.

[0121] Furthermore, the low-ceiling storage room 40 may be equipped with a security camera to film the interior, or an infrared sensor to detect people or animals. The sensing results from various security sensors, such as security cameras and infrared sensors, can be displayed on the display screen 11a of the in-house display 11. Therefore, the user U can check the situation inside the room without opening the indoor door 37.

[0122] According to this modified version, even if user U, who is a resident, is unable to directly receive the package P, the package P can be delivered securely by the third transport mobile unit 45, or even without the third transport mobile unit 45. In other words, delivery person D can directly receive the package P, and user U will feel less stressed about being at home but unable to directly receive the package P. In other words, it is possible to directly receive the package P with delivery person D who has come to deliver or collect the package P, while reducing stress during the handover of the package P. Moreover, the handover of the package P can be carried out in a highly secure manner. Furthermore, in this modified example, since the delivery of package P can be carried out under highly secure conditions, the delivery of package P may take place even when the resident, user U, is absent.

[0123] [Variation 6] In the above embodiment, the front door 3 of the entrance 1 was described as a vertically separated type, but in this modified example, although not shown in the diagram, the back door to the storage room is also a vertically separated type. Its function is the same as that of the front door 3, but because it is a back door to the storage room, it is more convenient as received packages P can be immediately stored in the storage room.

[0124] [Variation 7] In this modified example, although not shown in the diagram, an outdoor transport vehicle configured to autonomously navigate within the site where the user's house is built is deployed. This outdoor transport vehicle can move to the site boundary, receive the package P, and then automatically transport it to the front door (or vice versa in the case of pickup).
