Summary of the Invention

Problems to be Solved by the Invention

[0006] However, in the above - described conventional example, there is a problem that it is necessary to open a communication unit through - hole for inserting the communication unit in the door, and it is not easy to add an additional electronic device.

[0007] The present invention has been made to solve the above drawbacks, and an object thereof is to provide an electric lock control device that enables mounting an additional electronic device without opening a new through hole in the door and allows the additional electronic device to be easily added.

Means for Solving the Problems

[0008] According to the present invention, the above object is achieved by a device main body portion 6 that is fixed to the outdoor side wall surface 3 of the door 2 in a device fixing portion 1 and houses an electric lock control circuit in a housing space 5 formed by an outer shell constituent member 4 including the device fixing portion 1; an additional electronic device 7 that adds functions to the device main body portion 6; an additional device mounting portion 8 extends from the device fixing portion 1, and a waterproof packing 9 is interposed at the boundary between the device fixing portion 1, the additional device mounting portion 8, and the outdoor side wall surface 3 of the door 2; the additional electronic device 7 is disposed in a waterproof space 12 formed by the additional device mounting portion 8 and a cover body 11; and a wiring 13 of the additional electronic device 7 is drawn out behind the additional device mounting portion 8 from a wiring lead-out opening 14 formed in the additional device mounting portion 8 in the waterproof space 11, and then is drawn into the housing space 5 of the device main body portion 6 through a wire passing portion 15 formed at the boundary between the waterproof packing 9 and the additional device mounting portion 8. An electric lock control device is provided.

[0009] The electric lock control device includes a device main body portion 6 fixed to the outdoor side wall surface 3 of the door 2 and an additional electronic device 7. The device main body portion 6 is formed by housing an electric lock control circuit in a housing space 5 surrounded by an outer shell constituent member 4 subjected to appropriate waterproof treatment to prevent rainwater from entering. The electric lock control circuit has a predetermined function such as authentication or reception of an authentication signal, and the housing space 5 can store an electric actuator such as a motor 19 for driving a box lock 18 or the like disposed on the door 2.

[0010] Here, the outer shell component 4 refers to the component that constitutes the outer shell of the electric lock control device in a state fixed to the door 2. It can be a single outer case 17, or when an opening for mounting a display unit for external operation is provided in the outer case 17, etc., the display unit 20 that closes the opening after performing necessary waterproofing treatment to prevent water ingress into the interior is also included in the outer shell component 4.

[0011] The device main body part 6 is mounted by fixing the device fixing part 1 to the outdoor side wall surface 3 of the door 2, and a waterproof packing 9 is interposed between the wall surface 3 of the door 2 and the device fixing part 1 to prevent the intrusion of rainwater, etc. from the contact surface between the outdoor side wall surface 3 and the device fixing part 1.

[0012] The additional electronic device 7 is an electronic device that adds a new function to the functions pre - equipped in the device main body part 6. For example, it can be the addition of a new authentication means, an input means for new authentication information for the authentication means of the device main body part 6, etc.

[0013] The additional electronic device 7 is held in a waterproof space 12 formed on an additional device mounting part 8 extending from the device fixing part 1 of the device main body part 6. The above - mentioned waterproof packing 9 is extended to the boundary between the additional device mounting part 8 and the wall surface 3 of the door 2 to prevent water ingress from the boundary.

[0014] The waterproof space 12 is formed by the additional device mounting part 8 and the cover body 11 to prevent water ingress into the interior.

[0015] Furthermore, the wiring 13 from the additional electronic device 7 is drawn out from a wiring lead - out opening 14 formed in the additional device mounting part 8 within the waterproof space 12 to the back of the additional device mounting part 8, and then drawn into the accommodation space 5 of the device main body part 6 from a wire - passing part 15 formed at the boundary between the waterproof packing 9 and the additional device mounting part 8.

[0016] From the above, in the present invention, since the additional electronic device 7 is held on the additional device mounting part 8 extending from the device main body part 6, a new function can be added without newly making a hole or the like in the door 2.

[0017] In addition, since the additional electronic device 7 is housed in the waterproof space 12, there is no risk of water immersion. Furthermore, since the wiring 13 is drawn into the accommodation space 5 of the device main body 6 through the boundary between the waterproof packing 9 that retains the waterproof function from the waterproof space 12 and the additional device mounting portion 8, it is possible to reliably prevent rainwater or the like from entering the device main body 6 along the wiring 13.

[0018] Furthermore, the wiring 13 from the additional electronic device 7 is drawn out from the wiring lead-out opening 14 formed in the additional device mounting portion 8 within the waterproof space 12 to the back of the additional device mounting portion 8, and then drawn into the accommodation space 5 of the device main body 6 through the wire passing portion 15 formed at the boundary between the waterproof packing 9 and the additional device mounting portion 8.

[0019] From the above, in the present invention, since the additional electronic device 7 is held on the additional device mounting portion 8 extending from the device main body 6, a new function can be added without newly making holes or the like in the door 2.

[0020] In addition, since the additional electronic device 7 is housed in the waterproof space 12, there is no risk of water immersion. Furthermore, since the wiring 13 is drawn into the accommodation space 5 of the device main body 6 through the boundary between the waterproof packing 9 that retains the waterproof function from the waterproof space 12 and the additional device mounting portion 8, it is possible to reliably prevent rainwater or the like from entering the device main body 6 along the wiring 13.

[0021] The waterproof space 12 can be formed by covering the outdoor side surface of the additional device mounting portion 8 with the cover body 11. In this case, if a flexible waterproof sheet 10 is interposed at the contact portion between the additional device mounting portion 8 and the cover body 11, the edge of the cover body 11 presses against the waterproof sheet 10 just by fixing the cover body 11, ensuring the waterproof performance of this part. Thus, the assembly work is easy and it is possible to reliably prevent water from entering the waterproof space 12.

[0022] Further, although the waterproof sheet 10 can be disposed only at the contact portion with the additional device mounting portion 8 of the cover body 11, it can be formed in a sheet shape that covers the entire surface, or substantially the entire surface, of the additional device mounting portion 8 in consideration of ease of handling and the like. In this case, a wiring lead-out opening 14 that communicates with the wiring lead-out opening 14 of the additional device mounting portion 8 is formed in the waterproof sheet 10.

[0023] Furthermore, the device fixing portion 1 can be formed as a single component member independent of the other outer shell component members 4, for example, as a mounting plate body. In this case, in order to maintain the waterproof environment inside the device main body portion 6, necessary waterproof treatment is performed at the boundary between the device fixing portion 1 and the other outer shell component members 4.

[0024] On the other hand, if it is integrally formed with the outer case 17 that constitutes the main part of the outer shell component member 4, the structure becomes simple because there is no need to construct a waterproof structure at the boundary between the device main body portion 6 and the outer case 17.

Advantages of the Invention

[0025] According to the present invention, since the additional electronic device is fixed using the additional device mounting portion extending from the device fixing portion of the device main body portion installed on the outdoor side wall surface of the door, there is no need to open a through hole in the door.

[0026] Further, the additional electronic device is stored in a waterproof space constructed on the device fixing portion. Furthermore, the wiring to the additional electronic device is drawn into the accommodation space of the device main body portion via the wire passing portion formed at the boundary between the additional device mounting portion and the waterproof packing, so that it is possible to reliably prevent the intrusion of rainwater and the like into the additional electronic device and into the device main body portion via the wiring.

Embodiments for Carrying Out the Invention

[0028] FIG. 1 shows a locking device for an entrance door to which the present invention is applied. The locking device includes a box lock 18 embedded in a door 2, an electric lock control device for transitioning the locked and unlocked states of the box lock 18, and a lever handle 21 for opening the door 2 when the box lock 18 is in the unlocked state.

[0029] As will be described later, in this example, the electric lock control device is configured to directly operate the locked and unlocked states of the box lock 18 by a built-in motor 19. However, when the box lock 18 is an electric lock with a built-in power source, it can also be configured as a control device that outputs a drive signal to the electric lock.

[0030] The electric lock control device has a device main body part 6 and an additional electronic device 7 arranged in parallel with the device main body part 6. The device main body part 6 is formed by housing an electric lock control circuit in a housing space 5 formed by an outer housing constituent member 4 that constitutes the device outer shell.

[0031] The device outer shell of the device main body part 6 is formed to exhibit a waterproof function capable of preventing water from entering the housing space 5 when mounted on the outdoor side wall surface 3 of the door 2. In this example, the outer housing constituent member 4 includes an outer case 17 serving as a base, a liquid crystal display unit 20 described later, and a lid 22 that closes an opening for battery replacement of the power supply circuit.

[0032] As shown in Fig. 2, the electric lock control circuit includes a liquid crystal display unit 20 having a touch panel function for inputting a password, a control circuit board 23 that authenticates the password input from the liquid crystal display unit 20 and authenticates an authentication signal input from an additional electronic device 7 to be described later, and outputs a locking / unlocking signal when the authentication is successful, and a power supply circuit 24 including a battery. Also, in this example, the liquid crystal display unit 20 incorporates a card reader function for reading the authentication code of an authentication card key held by the user.

[0033] As shown in Fig. 2, the liquid crystal display unit 20 serving as the outer shell component 4 is fitted into the fitting recess 17a formed in the outer case 17. After that, a sealant is filled in the boundary between the fitting recess 17a and the liquid crystal display unit 20 to prevent water from entering the accommodation space 5. Similarly, an appropriate waterproof packing (not shown) is arranged at the boundary between the lid 22 that can be opened and the outer case 17.

[0034] Furthermore, a motor 19 for changing the locking / unlocking state of the box lock 18 is accommodated in the device main body 6 via a drive shaft 25.

[0035] The above device main body 6 is fixed to the outdoor side wall surface 3 of the door 2 at the device fixing portion 1 integrally formed with the outer case 17 and the additional device mounting portion 8 extending upward from the device fixing portion 1. To prevent rainwater and the like from entering from the boundary with the outdoor side wall surface 3, a waterproof packing 9 is interposed between the device fixing portion 1 and the additional device mounting portion 8 and the outdoor side wall surface 3 of the door 2. To ensure contact with the wall surface, a lip 9a is formed on the entire circumference of the back surface of the waterproof packing 9.

[0036] The device main body 6 is mounted in a state of being pressed against the wall surface 3. In the mounted state, the lip 9a of the waterproof packing 9 is in pressure contact with the wall surface of the door 2, and the device fixing portion 1 and the additional device mounting portion 8 are in pressure contact with the waterproof packing 9, preventing rainwater and the like from entering from the boundaries between the waterproof packing 9 and the wall surface 3, the waterproof packing 9 and the device fixing portion 1, and the waterproof packing 9 and the additional device mounting portion 8.

[0037] The additional electronic device 7 adds an authentication function using a smartphone to the electric lock control device in addition to the authentication means of the device main body 6, i.e., authentication by a password or a card key. It is formed on the additional device mounting portion 8 and held in a waterproof space 12 where a waterproof environment is maintained.

[0038] As shown in FIGS. 2 and 3, the additional electronic device 7 is formed by housing a predetermined circuit board in a housing 7a, and a harness (wiring 13) having a connector 13a for connecting to the control circuit board 23 described above is drawn out from the housing 7a. As shown in FIG. 3, a screw receiving portion 7b is provided on the housing 7a.

[0039] The waterproof space 12 is formed by covering the additional device mounting portion 8 with a cover body 11. As shown in FIG. 4, the cover body 11 is formed in a cup shape from a synthetic resin material in consideration of radio wave permeability, a pressing rib 11a is formed over the entire periphery of the open surface edge, and screw receiving holes 11b are provided at the four corners.

[0040] In order to maintain the waterproof performance of the waterproof space 12, a waterproof sheet 10 formed of a flexible material is fixed to the additional device mounting portion 8 of the outer case 17, and the cover body 11 is fixed using screws 26 so as to press the waterproof sheet 10 with the pressing rib 11a.

[0041] As shown in FIG. 3, the screw 26 passes through screw insertion holes 8a and 10a formed in the additional device mounting portion 8 and the waterproof sheet 10, passes through the screw receiving portion 7b formed in the housing 7a of the additional electronic device 7, and is screwed into the screw receiving hole 11b of the cover body 11. By tightening the screw 26, positioning of the additional electronic device 7 and pressing force of the pressing rib 11a of the cover body 11 against the waterproof sheet 10 are applied.

[0042] In FIG. 3, 9b indicates a recess for preventing interference with the head 26b of the screw 26.

[0043] With the cover body 11 fixed, the pressing rib 11a of the cover body 11 presses against the waterproof sheet 10 to deform the waterproof sheet 10, preventing the generation of a gap between the waterproof sheet 10 and the pressing rib 11a. Further, since the density of the waterproof sheet 10 increases due to the compression by the pressing rib 11a, the water resistance at the compressed part increases. In addition, the back surface of the pressed part of the waterproof sheet 10 by the pressing rib 11a is pressed against the surface of the additional device mounting part 8, preventing water from entering from the boundary between the additional device mounting part 8 and the waterproof sheet 10.

[0044] As described above, since the additional electronic device 7 is stored in the waterproof space 12 where waterproofness is guaranteed, it is protected from rainwater and the like.

[0045] Furthermore, as shown in FIGS. 2 and 3, wiring lead-out openings 14 are provided in the waterproof sheet 10 and the additional device mounting part 8. Each wiring lead-out opening 14 is formed to be large enough for the connector 13a connected to the tip of the wiring 13 connected to the additional electronic device 7 to pass through. With the additional electronic device 7 fixed, the waterproof space 12 is opened to the surface of the waterproof packing 9 via these two wiring lead-out openings 14.

[0046] Also, as shown in FIG. 5, a concave groove 16 is formed on the back surface of the additional device mounting part 8, that is, the surface corresponding to the waterproof packing 9, to communicate the wiring lead-out opening 14 of the additional device mounting part 8 with the accommodation space 5. The concave groove 16 is formed with a width and depth dimension that allows the insertion of the wiring 13 of the additional electronic device 7.

[0047] Therefore, in this example, with the additional electronic device 7 fixed, the wiring 13 drawn out from the additional electronic device 7 is drawn out from the wiring lead-out opening 14 and then drawn into the accommodation space 5 via the concave groove 16, and the electrical connection with the control substrate is completed by connecting the connector 13a to the connector 24a on the control circuit board 24 (see FIG. 2(a)).

[0048] When the waterproof packing 9 is mounted on the back surfaces of the device fixing part 1 and the additional device mounting part 8 from this state, only the wire passing part 15 formed by the surface of the waterproof packing 9 and the recess of the additional device mounting part 8 serves as a communication path connecting the waterproof space 12 of the additional electronic device 7 and the accommodation space 5 of the device main body part 6.

[0049] After that, when the electric lock control device is fixed to the door 2, as described above, the waterproof performance of the waterproof space 12, the accommodation space 5, and the wire passing part 15 is guaranteed. As a result, it is surely prevented that rainwater or the like flows into the accommodation space 5 along the wiring 13.

[0050] Prior to the operation of fixing the electric lock control device to the door 2, a sensor detection connector 27 is connected to the output terminal of a sensor (not shown in the figure) for detecting the locked / unlocked state of the box lock 18 or the open / closed state of the door 2 of the door 2. After that, the lever handle 21 is mounted and the installation of the locking device is completed.

[0051] In the installed state, as shown in FIG. 1, when the start button 28 arranged on the liquid crystal display unit 20 is operated, the control system is started and a numeric matrix for inputting a password is displayed on the liquid crystal display unit 20. When touching the displayed numbers, or covering a predetermined card key, or further operating a smartphone, an authentication code is acquired. When the input authentication code is authenticated and the locked / unlocked state of the box lock 18 or the state of the door 2 output via the sensor detection connector 27 matches the lock state transition condition, a locked / unlocked driver signal is set and the motor 19 is driven, and the drive shaft 25 is driven via the gear train 29, and the locked / unlocked state of the box lock 18 is transitioned.

[0052] In addition, in the above, the case where the wire passing part 15 through which the wiring 13 of the additional electronic device 7 is inserted is formed by the concave groove 16 of the additional device mounting part 8 has been shown. However, concave grooves can be formed in both the additional device mounting part 8 and the waterproof packing 9, and the culvert formed by both concave grooves can be used as the wire passing part 15, or the concave groove 16 can be formed only in the waterproof packing 9 to be the wire passing part 15.

[0053] In this example, the apparatus fixing part 1 and the additional apparatus mounting part 8 are shown as being integrally formed with respect to the outer case 17. However, after forming the apparatus fixing part 1 provided with the additional apparatus mounting part 8 separately with respect to the outer case 17, it can be fixed to the outer case 17, or only the additional apparatus mounting part 8 can be separately formed and connected to the apparatus fixing part 1 integrally formed in advance with the outer case 17 or to the outer case 17.

[0054] When the apparatus fixing part 1 or the additional apparatus mounting part 8 is formed as a separate outer shell component member 4, necessary waterproofing treatment is performed on the connecting part so that the waterproof performance in the accommodation space 5 is maintained.
