Description

[Technical field]

[0001] The present invention relates to a remote lock system and a management method for a remote lock system, which is provided with a mechanical keyless lock having multiple PIN input buttons into which a PIN of multiple digits or more can be input, and multiple lock buttons, which are connected to the Internet via wireless information media, and the PIN input information is transmitted as specific wireless information from a digital lock device via the keyless lock, and multiple PIN numbers are assigned to two types of locks, thereby simplifying the configuration and eliminating complex and cumbersome information exchange, allowing for accurate and rapid operation. [Background technology]

[0002] For example, there is a remote lock system and management method for a remote lock system that is equipped with multiple PIN input buttons as a locking device for the doors of an apartment building with multiple doors and an unspecified number of people entering and exiting, and that is connected to the Internet via Wi-Fi or Bluetooth, allowing the locking and unlocking states to be remotely controlled by the PIN input buttons, and that centrally manages the status of each room and the occupants via the cloud, issues entry authority remotely, keeps track of entry histories, reduces on-site response related to keys and entry, and achieves labor-saving and unmanned management of facility operations (see, for example, Patent Document 1).

[0003] However, this remote lock system and the method of managing the remote lock system required emergency unlocking using a physical key if the power source that operates each part, such as a DC power supply, ran out of battery or if the electronic equipment broke down. However, there is a problem in that it is troublesome and unreasonable to create a physical key for emergency unlocking and to prepare, carry and manage the physical key when it is needed.

[0004] The applicant has developed and proposed various keyless locks in which, instead of locks that are electrically or electronically operated, all components are constructed mechanically and organically linked to improve robustness and strengthen defensive capabilities, so that the lock can function even in emergencies when the power supply is cut off (see, for example, Patent Document 2). The keyless lock, for example, comprises multiple push buttons for inputting a secret code, a lock pin that moves in conjunction with the push buttons, and a lock plate that engages and disengages with the lock pin to lock and unlock.The secret code is input into the push buttons to store it, and the push buttons are operated based on the secret code to release the engagement between the lock pin and the lock plate, making it possible to unlock the door.

[0005] However, conventional keyless locks did not allow for the remote locking and unlocking of the house, the management of lock and unlock history, or the assignment of multiple PIN numbers. On the other hand, as mentioned above, conventional remote locking systems were cumbersome in that in the event of an emergency such as a dead battery or electronic device failure, it was necessary to use a physical key to unlock the door in an emergency.

[0006] Therefore, there has been a need for a remote lock system and a method of managing a remote lock system that can complement the functions of keyless locks and remote lock systems, improve defensive capabilities, and provide convenience of use, as well as rationalization and safety of lock management.

[0007] In order to solve such problems, a smart lock device is provided which is attached to the front door of a dwelling unit in an apartment building and which locks / unlocks the front door by a specific radio signal, a mobile phone which is carried by a contractor who is permitted to use the dwelling unit and has a function of sending out a specific radio signal for locking / unlocking the smart lock device, an authentication operation device for permitting unlocking of the smart lock device by the mobile phone, and a management server in which facial images of contractors are registered and which performs facial authentication of the unlocking operator. The authentication operation device is provided at the front door of the dwelling unit and has an operation button and a camera for performing facial authentication of the operator who unlocks the front door, and when the operation button is operated, an image captured by the camera is sent to the management server and managed. The server compares the received facial image from the camera with the facial image of the registered subscriber, and if there is a match, it sends an unlocking permission signal back to the authentication operation device. The authentication operation device, which has received the unlocking permission signal, authorizes the smart lock device to perform the unlocking operation. The smart lock device, which has been authorized to perform the unlocking operation, receives a specific wireless signal sent from a mobile phone and performs the unlocking operation, unlocking the front door. On the other hand, if a smart lock device receives a specific wireless signal for performing the unlocking operation when unlocking control is not authorized, it notifies the authentication operation device that it has received the specific wireless signal, and upon receiving this notification, it sounds a specific message to encourage facial authentication (see, for example, Patent Document 3). This is a smart lock linkage system.

[0008] However, the smart lock linkage system requires a smart lock device, a mobile phone, a management server, and an authentication operation device, which requires an operation button and a camera to perform facial authentication of the person unlocking the front door. The configuration is complex and requires matching by the management server and complex and cumbersome information exchange with the authentication operation device. This makes locking / unlocking the front door and managing it time-consuming, and prevents it from being used quickly. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0032] Below, we will explain the illustrated embodiment in which the present invention is applied to an apartment building. In Figures 1 to 16, 1 and 2 are apartment buildings consisting of multiple buildings, and each room is equipped with a Wi-Fi environment. Via Wi-Fi home routers 3 and 4, which are wireless LAN devices in each room, a locking device (described later), which is a wireless terminal in each room, is connected to the Internet, and input information from the terminal can be input to the cloud 5 (cloud computing: public). The input information and its storage (accumulated) information can be monitored from a remote administrator's personal computer 6 or smartphone.

[0033] A locking device 8 of the present invention is attached to the outside of the front door 7 of each room in the apartment buildings 1 and 2. The locking device 8 comprises a mechanical keyless lock 9 and an electrically or electronically operable digital lock device 10 with a transmission function, which are stacked and connected via a number of pipe screws described below. In this embodiment, the keyless lock 9 is disposed on the outside, and the digital lock device 10 is disposed on the inside of the keyless lock 9.

[0034] The keyless lock 9 has 12 password input buttons, i.e., push buttons 11, arranged in two rows for inputting and storing password information, and the numbers 0 to 9 and the letters A and B are engraved on the housing case 9a at the base of the keyless lock 9. 11 This allows the user to set up to 4,096 different PIN codes or PIN numbers. The push button 11 is configured so that it can be pressed from the outside to appear and disappear. When pressed, it displaces the end of the lock pin, which will be described later, in the pressing direction, and this pressing displacement is transmitted to the PIN input button, which will be described later, of the digital locking device 10, which then moves the button in the same manner to convert the input information into wireless information that can be output to the cloud 5.

[0035] The outline of the keyless lock 9 is substantially the same as that of Patent No. 5659194 already disclosed by the applicant, and is composed of a vertically elongated oval-shaped housing case 9a made of zinc alloy diecast metal with a roughly boat-shaped inner surface, and a plate-shaped housing cover 9b made of zinc alloy diecast metal that closes the inside of the case 9a.

[0036] The digital lock device 10 is formed in a vertically elongated oval shape slightly thinner than the keyless lock 9, and is surrounded by a vertically elongated oval remote housing case 10a made of zinc alloy diecast metal. Thin partition plates 12, 13 are arranged inside the case, and a vertically elongated annular seal rubber 14 is arranged around the outer partition plate 13. A vertically elongated oval remote case cover 15 made of zinc alloy diecast metal is arranged on the outside of the seal rubber 14.

[0037] An oblong button plate 16 is disposed on the inner surface of the remote housing case 10a, and a number of button insertion holes 17 are formed in the plate 16. A silicone rubber lock button 18 is disposed in the insertion hole 17 so as to be able to appear and disappear. The button insertion hole 17 is formed in the same phase and coaxial position as the push button 11 of the keyless lock 9, and a lock button 18 is disposed in the insertion hole 17 so as to be able to appear and disappear.

[0038] The lock buttons 18 are made of silicone rubber and molded into a flat, generally cylindrical shape, and are arranged in an array on a substrate (not shown). The lock button 18 is formed by molding two-layer button plates (not shown) that can be engaged with each other into a roughly sawtooth cross section, with a conductive member (not shown) arranged inside them. The conductive member (not shown) is arranged between adjacent contacts, and the contacts can be disconnected when the lock button 18 is pressed, ensuring that wireless information can be reliably turned on and off by the lock button.

[0039] In the figure, 19 to 22 are a number of pipe collars protruding from the back surface of the button plate 16. Pipe screws 23, 24 are screwed into the pipe collars 19, 21, screws 25, 26 are screwed into the insides of the pipe collars, and the screw shafts are screwed into the housing cover 9b of the keyless lock 9 to connect them. A screw 27 is screwed into the pipe collar 20 from the button plate 16 side of the digital locking device 10, and then screwed into the front door 7 in which the digital locking device 10 is embedded.

[0040] The pipe collar 22 is provided at the lowest position of the button plate 16, and a key plate, which will be described later, is rotatably disposed on the pipe collar 22. A cylindrical lever handle 29 is provided at the lower end of the keyless lock 9 so as to protrude outward and be rotatable, and a tubular handle shaft 30 is connected to the tip end of the lever handle 29 via a connecting bolt 31 .

[0041] A key cylinder 32 is provided at the tip of the handle shaft 30 so as to be movable together with the handle shaft 30, and a key plate 33 is attached to the tip of the key cylinder 32 by means of screws. The key plate 33 has a plurality of screw holes 34, into which screws 35 are screwed from the tip of the key cylinder 32. The length of the protrusion of the key plate 33 can be adjusted by changing the screw-in position, thereby making it possible to accommodate the thickness of the door 7.

[0042] A keyless lock 9 and a digital lock device 10 are attached integrally to the outer surface of the door 7, and a lock mounting hole 36 is formed in the open end surface of the door 7, into which a well-known box-shaped door lock 37 is inserted and attached. The outline of the door lock 37 is substantially the same as that of Patent No. 6484212 disclosed by the applicant, and its structure comprises a cam arm that can rotate around a square hole, a set spring that urges the cam arm so that it can rotate counterclockwise, and a latch bolt 38 that appears and disappears from the front panel in conjunction with the operation of the cam arm and can be engaged and disengaged with a troyoke (not shown) provided on the door frame, and the lever handle 29 and thumb turn are linked to a lock shaft 39 described later.

[0043] The thumb turn case 40 that houses the thumb turn is formed in a roughly vertically elongated rectangular box shape, with multiple dry batteries (not shown) that serve as a DC power source located at the top inside, and a motor 41 driven by the DC power source arranged diagonally directly below them. A worm gear 43 is connected to a drive shaft 42 of the motor 41, and a pinion 44 meshes with the worm gear 43. An intermediate gear 45 is provided coaxially with the pinion 44, and a large-diameter main gear 46 meshes with the intermediate gear 45. A thumb turn knob 48 is coaxially connected to an output shaft 47 of the main gear 46. By rotating the thumb turn knob 48 or by rotating the lever handle 29 open or closed, the latch bolt 38 of the door lock 36 is engaged with and disengaged from the troyoke, making it possible to open and close the door 7.

[0044] After being unlocked, the digital locking device 10 performs an auto-lock function when the latch bolt 38 of the door lock 37 comes out of the troyoke provided on the door frame, and after a certain period of time, the latch bolt 38 is made to engage with the troyoke, making the auto-lock operable. In this embodiment, the auto-lock function can be set by a timer (not shown), and the set time can be set to, for example, 5 to 20 seconds, 30 seconds, 1 minute, 5 minutes, 10 minutes, 20 minutes, 25 minutes, or 30 minutes.

[0045] In the embodiment, a DC power supply is used as a power supply for the motor (not shown), but other power supply means can be used. However, the DC power supply has the advantage of simple wiring and easy maintenance. In the figure, reference numeral 49 denotes a light-emitting piece provided at the upper end of the housing case 9a, with a plurality of LEDs embedded therein so as to be able to light up when the digital lock device 10 is activated. The light-emitting piece 49 is capable of emitting light of different colors when the digital locking device 10 is initially set up, when it is in use, and when it is stopped, allowing the usage status of the digital locking device 10 to be visually confirmed, improving convenience in use and ensuring accurate and stable use.

[0046] On the other hand, the outline of the keyless lock 9 is substantially the same as that of Patent No. 5659194 already disclosed by the applicant, and its configuration, as shown in Figures 17 to 42, has a button pressing plate 50, a lock plate 51, and a reset plate 52 stacked between a housing case 9a and a housing cover 9b. Of these, the button retainer plate 50 is formed into a roughly rectangular plate by zinc alloy die casting, with screw holes 53 formed in its four corners and in the center. The button retainer plate 50 is attached by inserting screws 54 into the screw holes 53 and screwing them into screw holes 55 formed on the inside of the case housing 9a.

[0047] A plurality of lock pin insertion holes 56 are arranged in two rows in the button pressing plate 50, and the insertion holes 56 are formed to correspond to the positions of the button holes and clear button holes described below, and recesses 57 are formed in the inner opening edge of the lock pin insertion holes 56. Square grooves 58 are formed on both sides of the recessed hole 57, and leg pieces, which will be described later, are slidably inserted into the square grooves 58. In the drawing, reference numeral 59 denotes a mountain-shaped engagement protrusion protruding from the peripheral surface of the recessed hole 57, and reference numeral 128 denotes a shallow recessed hole formed in the outer opening edge of the lock pin insertion hole 56.

[0048] A clear pin insertion hole 60 is formed at the upper end of the button pressing plate 50, a recess 57 is formed at the inner opening edge of the clear pin insertion hole 60, and square grooves 62 are formed on both sides of the recess 57, and the leg pieces 115, 115 are slidably inserted into the square grooves 62. In the drawing, 63 and 64 are engagement protrusions provided at opposing positions on the inside of the recessed hole 57, which are arranged so as to be able to engage with the clear cam of the clear pin described later, and regulate the rotation angle of the clear pin described later.

[0049] The lock plate 51 is formed into a vertically long rectangle by pressing a steel plate, and a plurality of lock holes 67, 68 are arranged in two rows at positions corresponding to the button hole 65 and the clear button hole 66, and these lock holes 67, 68 are formed symmetrically on the left and right. In the drawing, the lock holes 67 and 68 are provided with corresponding PIN markings on their opening edges.

[0050] The lock holes 67, 68 are formed in a roughly T-shape with rectangular cutout grooves 69 formed on both the left and right sides of the upper part thereof. An inclined engagement edge 70 is formed on one side of the intersection between the cutout grooves 69 and the lock holes 67, 68. The engagement edge 70 is positioned so as to be able to engage with the lower side surface of a cam flange of the lock pin, which will be described later, making it possible to prevent the lock plate 51 from moving upward. A mountain-shaped projection 71 is provided inwardly at the center of the upper end of each of the lock holes 67, 68 and is arranged so as to be engageable with the upper surface of a cam flange of a lock pin (described later), thereby making it possible to prevent the lock plate 51 from moving upward.

[0051] In the figure, 72 is a through hole formed in an approximately T shape at the upper end of lock plate 51, with rectangular cutout grooves 73 formed on both the left and right sides of the upper part of the hole, and 74 is a approximately L-shaped bent piece formed at the lower end of lock plate 51, which is placed so as to be able to engage with the flat portion of a driving cam described later. After lock 9 is unlocked, the driving cam rotates to release the above-mentioned placement, allowing lock plate 51 to move upward.

[0052] A long hole 75 is formed in the lower end of the lock plate 51, and a pin hole 75 is formed in the lower end of the button retainer plate 50, into which a connecting pin 76 is inserted to enable them to move together. In the figure, reference numeral 77 denotes a spring holder bent at a right angle to the upper left and right ends of the lock plate 51. A spring 78 is inserted between the spring holder 77 and the inner protruding wall (not shown) of the case housing 9a, and the elasticity of the spring 78 urges the lock plate 51 downward.

[0053] The reset plate 52 is formed into a roughly rectangular plate by zinc alloy die casting, and has a plurality of lock pin holes 79 arranged in two rows at positions corresponding to the button hole 65 and the clear button hole 66. A spring hook pin 80 protrudes from the upper part between these lock pin holes 79, and pins 81 protrude directly below the spring hook pin 80 and from the lower outer side of the lock pin hole 79. These pins 81 are crimped to connect to a reset pressing plate 82.

[0054] The reset pressing plate 82 is formed into a rectangular plate by pressing a steel plate, and has lock pin holes 83 of the same shape as the lock pin holes 79 arranged in two rows at positions corresponding to the lock pin holes 79 . In addition, a pin hole 84 into which the spring hook pin 80 can be inserted is formed at a position on the reset pressing plate 82 corresponding to the spring hook pin 80, and a pin hole 85 into which the pin 80 can be inserted is formed at a position corresponding to the pin 80.

[0055] The coil portion 86a of the reset spring 86, which is a torsion spring, is inserted into the spring hook pin 80, and both ends of the spring are arranged to protrude obliquely between the lock pin holes 79, 79, and the terminal portions are arranged so as to be able to engage with the conical surface of the lock pin described later. In the figure, reference numeral 87 denotes a protruding piece protruding from the lower end of the reset plate 52, the protruding piece 87 being arranged back to back with the bent piece 74 and placed so as to be engageable with a flat portion of a drive cam which will be described later.

[0056] After the keyless lock 9 is unlocked, the drive cam rotates to push up the reset plate 62, moving the end of the reset spring 86 away from the lock pin 88 and reducing the engagement force of the reset spring 86. The elasticity of the lock spring 89 moves the lock pin 88 upward, allowing the pin 88 to return to its original position. In the figure, reference numeral 90 denotes a clear pin insertion hole formed in the upper end portion of the reset plate 52, with a tapered surface 90a formed on the inner surface on the upper side thereof, into which the tapered cam of the clear pin described later is inserted so as to be engageable.

[0057] In the figure, reference numeral 91 denotes a spring pin protruding from the upper end of the reset plate 52. A set spring 92 is inserted between the pin 91 and the inner protruding wall (not shown) of the case housing 9a, and the elasticity of the spring 92 urges the reset plate 52 and the reset pressing plate 82 downward.

[0058] The housing case 9a is formed into an oval disk shape by zinc alloy die casting, and a plurality of stepped lock pin holes 93 are arranged in two rows at positions corresponding to the button hole 65 and the clear button hole 66. An annular groove (not shown) is formed on the outside of the inner rim of the lock pin hole 93, and a conical lock spring 89 is inserted between the annular groove and a tapered flange of the lock pin, which will be described later. The elasticity of the spring 89 urges the lock pin 88 toward the inside of the cover plate 9b.

[0059] A handle insertion hole 94 is formed at the lower end of the cover plate 9b, and screw holes 95 are formed at the upper and lower ends of the cover plate 9b, so that screws 96 can be inserted from the outside and screwed into screw holes (not shown) in the case housing 9a. In the figure, 97, 98 are shaft screw insertion holes formed at the upper and lower ends of the cover plate 9b, 25, 26 are shaft screws that can be screwed into the pipe screws 23, 24, and the other end can be screwed into a screw hole (not shown) of the case housing 9a.

[0060] The lock pin 88 is formed into a generally axial shape by die-casting of brass or zinc alloy, with a small diameter portion 88a and a large diameter portion 88b of different diameters formed at both ends. The small diameter portion 88a at the tip side is formed with a square shaft portion 99, and a square hole of a spring bearing described later is fitted into the square shaft portion 99 for installation. A cone flange 100 having an approximately truncated cone shape is formed on the base side of the large diameter portion 88b, and two cam flanges 101, 102 consisting of arc-shaped plate cams are spaced apart from each other and protrude in opposite directions between the cone flange 100 and the angular shaft portion 99.

[0061] Of these, a cam flange 101 is arranged on the cone flange 100 side, and a hexagonal shaft portion 100a is formed coaxially with the lock pin 88. A cam flange 101 having a slightly smaller diameter than the cone flange 100 protrudes from one side of the shaft portion 100a. The cam flange 100a is formed as a plate cam that is the same diameter as the cam flange 101 and slightly thicker, and a circular shaft portion 102a is formed coaxially with the lock pin 88. A cam flange 102 protrudes from the shaft portion 102a on the opposite side to the cam flange 101.

[0062] A groove 103 is formed at the shaft end of the large diameter portion 88b, and a tool such as a screwdriver, a coin, etc. engages with the groove 103, and the pin is rotated 180° from the assembled position and positioned when inputting and changing the pin. In the figure, reference numeral 104 denotes a PIN display slit formed at the axial end of the large diameter portion 88b at a position perpendicular to the groove 103, and the slit 104 is positioned horizontally on the inside of the cover plate 9b to enable the input of a PIN to be indicated, and the slit 104 is positioned horizontally on the outside of the cover plate 9b to enable the input of non-PIN information to be indicated.

[0063] A secret code indication consisting of ten numbers from 1 to 0 and two letters, A and B, is engraved on the outer opening edge of the lock pin hole 79 of the cover plate 9b, making the secret code of the lock pin 88 corresponding to the push button 11 visible. A C-shaped clear button marking is engraved on the opening edge of the lock pin hole 79 of the cover plate 9b.

[0064] The clear pin 105 is formed into a generally axial shape by die-casting brass or zinc alloy, one end of which is inserted into the button washer 113 inside the clear button 111, and the other end of which is rotatably inserted into the clear pin support hole 163.

[0065] The upward movement of the reset plate 52 separates the end of the reset spring 86 from the lock pin 88, reducing the engagement force, and allows the elasticity of the lock spring 89 to return the lock pin 88 to its original position.

[0066] A handle shaft 30 is connected to the inside of the case housing 9a, and a drive cam 106 is rotatably attached to the tip of the handle shaft 30 via a torsion spring (not shown). The elasticity of the torsion spring allows the drive cam 106 to rotate back to its original position. The drive cam 106 is formed into a cylindrical shape by zinc alloy die casting, with a flat portion 106a formed at its upper end. The flat portion 106a accommodates the bent piece 74 of the lock plate 51 and the protruding piece 87 of the reset plate 52 in a back-to-back engageable manner.

[0067] The case housing 9a is formed by zinc alloy die casting into an oval shape with a bottom, with a plurality of button holes 65 arranged in two rows at the bottom, and a single clear button hole 66 arranged above them.

[0068] The button hole 65 and the clear button hole 66 are formed to have the same diameter, and the push button 11 and the clear button 107 are inserted into these. The push button 11 and the clear button 107 are formed into a deep cylindrical shape by pressing steel plate, and flange portions 11a, 107a are formed by bending them on their opening sides, and these flange portions 11a, 107a are positioned so that they can engage with the opening edges of the button hole 65 and the clear button hole 66. A button washer 108 is inserted inside the push button 11 and the clear button 107, which are formed into a disk shape by pressing a steel plate, and a pair of legs 109 are provided on each of them so as to face each other and protrude from their relative positions.

[0069] The cross section of the leg piece 109 is formed into an approximately Z or L shape, with an expanded diameter portion 109a formed in the middle thereof, and the expanded diameter portion 109a and flange portion 110a are arranged so that the opening edges of the push button 11 and the clear button 107 can engage with each other. A button spring 111 is disposed between the opposing legs 109, and the button spring 111 urges the button washer 108, the push button 11 and the clear button 107 by its elasticity so that they can protrude outward.

[0070] In the figure, reference numeral 112 denotes a spring holder disposed on one side of the button spring 111, which is formed into a small, approximately rectangular plate shape by zinc alloy die casting, with a square hole 113 formed inside. In addition, reference numeral 114 denotes a square core rod protruding from the drive cam 106 . In the embodiments, the present invention is applied to apartment buildings or individual dwelling units that are used frequently by specific users, but it is not limited to this and can also be applied to ordinary homes, companies, schools, various facilities or offices, and other places that are used infrequently by a small number of users, such as warehouses, event venues, and guardhouses at construction or building sites.

[0071] The lock device 8 of the present invention constructed in this manner is as shown in Figures 2 to 8, and is equipped with a mechanical keyless lock 9 and an electrically or electronically operable digital lock device 10, which are stacked and connected inside and outside. In this embodiment, the keyless lock 9 is placed on the outside, the digital lock device 10 is placed on the inside of the keyless lock 9, and these are fixed by screwing screws 25, 26 into one ends of multiple pipe screws 23, 24, and the other ends are inserted from the front of the digital lock device 10 into the through holes on the front surface of the door 7, and the other ends of the pipe screws 23, 24 are fixed by screwing screws into the back surface of the door 7.

[0072] The keyless lock 9 is substantially the same as that disclosed by the applicant in Patent No. 5659194, and its configuration, as shown in Figures 17 to 42, consists of a button pressing plate 50, a lock plate 51, and a reset plate 52 stacked between a housing case 9a and a housing cover 9b, and its assembly is substantially the same as that of the conventional lock.

[0073] On the other hand, the digital lock device 10 is formed in a vertically elongated oval shape slightly thinner than the keyless lock 9, and is surrounded by a vertically elongated oval housing case 10a made of zinc alloy diecast metal, on the inside of which are placed thin partition plates 12 and 13, a vertically elongated ring-shaped seal rubber 14 is placed around the outer partition plate 13, and a vertically elongated oval case cover 15 made of zinc alloy diecast metal is placed on top of the seal rubber 14, and these are assembled by fastening them with various screws. This situation is as shown in Figure 7. Therefore, as described above, the digital lock device 10 is assembled by stacking and connecting the various components and fastening them with various screws, which makes it easier and faster to assemble than if they were firmly connected, and allows for easy changes to the PIN code of the keyless lock 9.

[0074] When assembling the digital locking device 10 to the keyless lock 9 thus assembled, the digital locking device 10 is placed on the back of the keyless lock 9, and these are connected using the pipe screws 23, 24 and various screws and bolts as described above. Therefore, since no particularly complicated assembly is required, the assembly can be easily performed. This situation is shown in Figures 4 to 6 and 8 to 11.

[0075] Next, the keyless lock 9 and digital lock device 10 thus assembled are attached to the exterior of the front door 7 of each dwelling unit. In this case, a lock mounting hole 36 is formed in advance at a mid-high position on the side end face of the door 7, and the already assembled door lock 37 is inserted and embedded into this lock mounting hole 36, and the front panel is fixed to the side end face of the door 7 with screws.

[0076] After this, the keyless lock 9 and digital locking device 10 are overlapped and connected on the exterior surface of the door 7, the thumb turn case 40 is positioned at the corresponding position on the interior side of the door 7, and these are connected using pipe screws 23, 24 and screws 27, and the key plate 33 protruding from the back of the digital locking device 10 is connected to the output shaft 47 of the thumb turn case 40 via the lock shaft 39. This situation is as shown in Figures 12 and 13. In this way, the keyless lock 9, digital lock device 10, and thumb turn case 40 are connected via the lock shaft 39 to the inside and outside surfaces of the door 7 in which the door lock 37 is embedded, so that the connection work can be performed easily and quickly.

[0077] In this case, the above-mentioned installation in an apartment building is carried out in an environment where each dwelling unit is equipped with a wireless LAN device, and after installation, the terminal in each room, i.e., the lock device 8, is connected to the Internet via the Wi-Fi home routers 3 and 4, which are the wireless LAN devices in each room. In this case, the keyless lock 9, digital lock device 10, thumb turn case 40, etc. are installed in a uniform position on the door 7 of each dwelling unit, so that the work and processing on the door 7 can be standardized, and this can be done rationally, easily, and inexpensively, compared to installation on an individual residence.

[0078] The locking device 8 attached to the inside and outside surfaces of the front door 7 of each dwelling unit is as shown in Figures 2 to 8, with a keyless lock 9 and digital lock device 10 connected and attached as a single unit at a mid-high position on the outside surface of the front door 7, and a thumb turn case 40 attached at a mid-high position on the inside of the door 7. In this case, the locking device 8 has a keyless lock 9 exposed on the front surface of the door 7 and a digital locking device 10 concealed on the back surface of the keyless lock 9. However, since the digital locking device 10 is thin and closely overlaps the keyless lock 9, the projection dimension from the front door 7 is suppressed and the appearance of the door 7 is not marred.

[0079] In such a locking device 8, the keyless lock 9 is used in the same manner as in the conventional locking device 8. That is, the push button 11 is pressed based on a previously selected secret code, which is then stored and the lock is activated. Thereafter, the push button 11 is pressed based on this secret code to unlock the door. The password is input by first rotating the lock pin 88 exposed in the lock pin hole 79 opened in the cover plate 9b by 180 degrees.

[0080] That is, immediately after installation or before the PIN is entered, the PIN display slit 104 of the lock pin 88 is positioned on the outside, and the PIN is entered from this state by rotating the lock pin 88 180°. At that time, a tool such as a screwdriver is engaged with the corresponding concave groove 103 of the lock pin 88 based on the PIN display engraved on the cover plate 9b, and the lock pin 88 is rotated.

[0081] The lock pins 88 into which the PIN has been input in this manner have their PIN display slits 104 positioned inside the cover plate 9b, and it is possible to confirm whether or not the PIN has been input based on the position of the PIN display slits 104. In this embodiment, the PIN (personal code) "14580A" is input into six lock pins 88, and this situation is shown in Figure 34. The status of the lock pin 88 when such a PIN code has been input and the lock pin 88 when no PIN code has been input are as shown in Figures 32 to 34, where the cam flange 100 of the lock pin 88 when a PIN code has been input engages with the lock hole 67 or 68 of the lock plate 51, and one side end of the lock pin 88 moves away from the engagement edge to prevent the lock plate 51 from moving upward, thereby forming a locked state.

[0082] At that time, the elasticity of the lock spring 89 interposed between the housing cover 9b and the small diameter portion of the cam flange 100 biases the lock pin 88 so that it can move inward. Also, in the non-password-input lock pin 88, the cam flange 100 engages with the lock hole 67 or 68 of the lock plate 51, and one end of the pin is separated from the engagement edge portion, allowing the lock plate 51 to move upward.

[0083] On the other hand, the digital locking device 10 has a plurality of lock buttons 18 arranged upright on a substrate, with the upper end faces of the buttons being positioned on the same plane as shown in FIG. When such a digital locking device 10 is placed in close contact with the back of the keyless lock 9, after the keyless lock 9 is locked, that is, after the lock pin 88 is released from the pressure displacement, the rear end of the lock pin 88 moves slightly away from the lock button 18 of the digital locking device 10, and the connection or engagement between the rear end of the lock pin 88 and the lock button 18 is severed.

[0084] This situation is as shown in Figure 5, where the lock button 18 is not pressed due to the displacement of the lock pin 88, so the transmission of wireless information associated with the pressing of the lock button 18 is stopped, and no wireless information is transmitted from the digital lock device 10 to the Wi-Fi home routers 3 and 4.

[0085] When the keyless lock 9 is locked, the push button 11 is pressed to displace the lock pin 88, causing the lock pin 88 to move inward against the elasticity of the button spring 11 and the lock spring 89, and its rear end comes into contact with the lock button 18, causing the button 18 to move inward against its elasticity. That is, the corresponding lock button 18, which is arranged in phase with and coaxially with the lock pin 88, is pressed, and wireless information is input.

[0086] The wireless information input by the corresponding lock button 18 is substantially the same as the password input by the lock pin 88, and wireless information corresponding to the password input is transmitted from the digital lock device 10. The lock button 18 is molded with a two-layered, roughly sawtooth cross section with concave and convex buttons that can engage with each other, and conductive members arranged inside them are placed between adjacent contacts. The contacts can be separated when the lock button 18 is pressed, turning the contacts ON and OFF, and when the contacts are ON, the wireless information is transmitted.

[0087] The transmitted radio waves are input to the Wi-Fi home routers 3 and 4 in each room, and then input from the home routers 3 and 4 to the cloud 5, which inputs the input information, i.e., the locking status of the terminal's locking device 8 and the locking time.

[0088] When the door is locked in this manner and the front door 7 is to be unlocked from the indoor side and opened, the thumb turn knob 48 on the indoor side is rotated open, and the rotational displacement is transmitted to the lock shaft 39, key plate 33, key cylinder 32, and handle shaft 30, rotating the drive cam 106 which is coaxial with the handle shaft 30, disengaging its flat surface 106a from the lower end of the reset plate 52, and pushing the reset plate 52 down by the elasticity of the spring, after which the lever handle 29 is rotated to open the front door 7.

[0089] At that time, the time when the door 7 is opened is detected by a timer (not shown), and the detection information is input to the cloud 5. Also, the opening information of the door 7 is input to the power supply circuit of the motor 41 of the thumb turn case 40. In this way, DC power is supplied from the power supply circuit to the motor 41, the motor 41 starts, the output shaft 42 drives, and the driving force is transmitted to the worm 43, which rotates and rotates the meshing intermediate gear 44.

[0090] As a result, the pinion 45 coaxial with the intermediate gear 44 rotates, causing the main gear 46 meshing with the pinion 45 to rotate, and the coaxial output shaft 47 moves in unison, and the lock shaft 39 cooperates with this to rotate the lever handle 29 of the keyless lock 9 to close. This causes the cam arm of the door lock 37 to rotate, and the latch cam 38 cooperates with this to protrude and engage with the troyoke provided on the door frame, automatically locking the open door 7.

[0091] Therefore, the front door 7 is locked a predetermined time after it is opened, providing an anti-theft effect. In this embodiment, this automatic lock function can be set for a certain period of time using a timer (not shown), and the set time can be set to any of 5 to 20 seconds, 30 seconds, 1 minute, 5 minutes, 10 minutes, 20 minutes, 25 minutes, and 30 minutes, for example. In this case, if an emergency occurs such as the DC power supply running out of battery or electronic equipment breaking down, the manager can know the situation remotely via a PC or smartphone and can perform emergency unlocking using a physical key. In this case, by operating the non-electric keyless lock 9 to unlock the door, the above-mentioned emergency can be dealt with promptly without needing a physical key as in the past.

[0092] On the other hand, when the keyless lock 9 is locked and the door 7 is to be unlocked from the exterior side to open the door 7, the lock on the exterior side, that is, the keyless lock 9, is unlocked. In this case, based on the PIN input information stored in the keyless lock 9, the corresponding push button 11 is pressed, each lock pin 88 is pressed to cancel the stored PIN input, the engagement between the lock pin 88 and the lock holes 67, 68 of the lock plate 51 is released, the lock plate 51 is unlocked in conjunction with the rotational displacement of the lever handle 29, and the front door 7 is opened.

[0093] That is, six lock buttons 18 arranged in phase and on the same axis as the lock pin 88 are pressed to input wireless information, which is substantially identical to the PIN input of the lock pin 88, and wireless information corresponding to this PIN input is transmitted from the digital locking device 10. In this case, the lock button 18 is molded with a two-layered, roughly sawtooth cross section with concave and convex shapes that allow the button covers to engage with each other, and the conductive members placed inside them are arranged between adjacent contacts, making the contacts separable when the lock button 18 is pressed, turning the contacts ON and OFF, and transmitting the wireless information when the contact is ON.

[0094] The wireless information is input to the Wi-Fi home routers 3 and 4, which are wireless LAN devices in each room, and then input from the home routers 3 and 4 to the cloud 5, which inputs the input information, i.e., the unlocked status and unlocking time of the lock device 8, which is a terminal, and also the opening time of the door 7. After the front door 7 is opened in this way, it is automatically locked after a certain time in the same manner as described above, thereby exerting its anti-theft effect. The auto-lock operation functions in the same manner as described above, and the auto-lock operation is input to the cloud 5, and the input information, i.e., the locking state of the terminal locking device 8 and the locking time, and the closing time of the door 7 are also input.

[0095] In this way, the unlocked status of the locking device 8, the unlocking time, the time the door 7 was opened, the time the lock button 18 of the digital locking device 10 was pressed, the locked status of the locking device 8, the locking time, and the time the door 7 was closed are input into the cloud 5, as well as the usage history of the vacant rooms in each unit and the remaining battery charge of the DC power supply device.

[0096] Therefore, the remote managers of the apartment buildings 1 and 2 can use the computer 6 or smartphone in the management room to monitor the various information and storage information entered into the linked cloud 5, and can remotely check the status of each unit, thereby streamlining management of the units and ensuring security. This eliminates the need for the managers to travel to each unit to solve individual problems, thereby streamlining management.

[0097] In this way, the present invention is suitable for a remote lock system and a method of managing a remote lock system, since it comprises a mechanical keyless lock equipped with multiple PIN input buttons into which a PIN of multiple digits or more can be input, and multiple lock buttons, which are connected to the Internet via wireless LAN, and specific wireless information is transmitted from the digital lock device when the PIN is entered by the keyless lock, and multiple PINs are assigned to the two locks, thereby simplifying the configuration and eliminating complex and cumbersome information exchange, allowing the system to be operated accurately and quickly.
