Description

【Technical Field】 【0001】 The present invention relates to a locking device. 【Background Art】 【0002】 An electric lock includes a lock case provided inside a door, and a housing provided on a side surface of the indoor or outdoor side of the door. The housing may also serve as a pedestal for a handle. The lock case includes a deadbolt and a motor for driving the deadbolt. The housing includes a non-contact IC card reader, a numeric keypad, a biometric authentication device, etc., and a circuit board for controlling the motor according to the authentication results. A wiring for supplying a control signal and power to the motor is provided between the lock case and the circuit board. 【0003】 For the overall efficiency improvement of a series of operations including packaging, delivery, installation, etc. of the electric lock, it is desirable to ship from the factory with the lock case incorporated in the door and attach the housing to the door when installing the door. In this case, an operation of connecting a wiring whose one end is connected to the lock case to the circuit board occurs. However, since it is time-consuming to once remove the lock case incorporated in the door, connect the wiring to the circuit board, and then incorporate the lock case into the door again, it is desirable to connect the other end of the wiring to the circuit board while the lock case is incorporated in the door. However, when the lock case is incorporated in the door, since the wiring is also stored inside the door, there is a problem that it becomes difficult to pull out the wiring from the door during installation. 【Prior Art Documents】 【Patent Documents】 【0004】 【Patent Document 1】 Japanese Patent Application Laid-Open No. 2024-87220 【Summary of the Invention】 【Problems to be Solved by the Invention】 【0005】 Conventionally, technologies to facilitate the wiring of electric locks have been considered. For example, Patent Document 1 discloses a wiring aid that is elastic and formed in the shape of a thin plate, has a guide portion at its tip that is wound in the thickness direction when unloaded, and has a connector holding slit at its rear end through which the connector is inserted and the connector is held. However, this wiring aid is based on the premise that the harness is introduced into the door body from the wiring opening on the introduction side of the door body and pulled out from the wiring opening on the exit side on the opposite side of the door body, and therefore cannot be applied to the purpose of pulling out the wiring from inside the door. 【0006】 Considering the above circumstances, the present invention aims to easily bring wiring, which is housed inside the door together with the lock case, to the outside of the door. [Means for solving the problem] 【0007】 To solve the above problems, the locking device according to the present invention comprises a lock case incorporated inside a door, wiring with one end connected to the lock case, a fastener for holding a portion of the wiring, a first detachable part provided on the side of the lock case, to which the fastener can be detached and which is provided at a position corresponding to an opening formed in the side of the door, and a housing attached to the side of the door to which the other end of the wiring is connected. 【0008】 The fastener is formed in a strip shape, the first attachment / detachment portion is provided on the indoor side and the outdoor side of the lock case, and both ends of the fastener may be detachable. 【0009】 The lock case has an operating member connected to an operating member for operating the locking device, and the first attachment / detachment portion may be provided on the operating member. 【0010】 The housing may also include a second detachable section from which the fastener holding the wiring can be attached and detached. [Effects of the Invention] 【0011】 According to the present invention, wiring stored inside the door along with the lock case can be easily pulled out to the outside of the door.

Figure 1(B) is a perspective view showing the locking device 1. Figure 2(A) is an interior side view of the locking device 1. Figure 2(B) is an exterior side view of the locking device 1. In each figure, U, Lo, L, R, Fr, and Rr indicate top, bottom, left, right, front, and back, respectively. These directions are defined only for the sake of explanation. 【0015】 The locking device 1 is installed on the leading edge side of the door 2. In Figure 1, the front side is the interior side, the rear side is the exterior side, the right side is the leading edge side, and the left side is the hinge side. The locking device 1 is an electric lock that drives the deadbolt 27 with electricity. In this embodiment, the door 2 is a hinged door, but the door 2 may also be a sliding door. 【0016】 In this embodiment, a push-pull lock is shown as an example of the locking device 1. In the push-pull lock, the housing 8 also functions as a base that supports the handle 3 at two locations, above and below. Lock cases 5 are provided at two locations corresponding to the upper and lower housings 8. A latch bolt 35 is provided in either the upper or lower lock case 5 (in this embodiment, the upper lock case 5). The latch bolt 35 extends and retracts through the push and pull actions of the handle 3 by the user. However, the push-pull lock is merely an example, and the configuration as a push-pull lock is not an essential requirement of the present invention. Furthermore, the lock case 5 may be provided at only one location or at three or more locations. 【0017】 Figure 3(A) is an indoor side view of the outer case 4.

Figure 10(B) is a cross-sectional view showing the CC section of Figure 10(A). Figure 10(C) is a perspective view showing the state after the fastener is attached to the second attachment / detachment part of the housing according to one embodiment of the present invention. 【0018】 The locking device 1 includes an outer case 4, a lock case 5, wiring 6, a fastener 7, and a housing 8. 【0019】 [Outer case] The lock case 5 and housing 8 are attached to the outer case 4 (see Figure 3). The outer case 4 is embedded in the door edge side of the door 2 (see Figure 1). The indoor side surface 11, the outdoor side surface 12 (not shown), and the door edge side surface 13 of the outer case 4 form a surface that is roughly the same as the indoor, outdoor, and door edge sides of the door 2, respectively. Note that the outer case 4 does not need to be a separate component from the door 2, and the door 2 may also perform the functions of the outer case 4. Therefore, in this invention, the outer case 4 is identified as a part of the door 2. 【0020】 An opening 13A is formed on the door-side side portion 13 of the outer case 4, exposing the door-side side portion 25 of the lock case 5. A housing 8, which serves as a base for supporting the handle 3 at two locations, upper and lower, is attached to the indoor side portion 11 of the outer case 4 (see Figures 1 and 2). Screw holes 14 for attaching the upper and lower housings 8 and an opening 11A for exposing the fastener 7 are formed on the indoor side portion 11 of the outer case 4. An opening 12A (not shown) for exposing the fastener 7 is formed on the outdoor side portion 12 (not shown) of the outer case 4. 【0021】 [Lock case] The upper and lower lock cases 5 (see Figures 1 and 2) have the same basic configuration except that the upper lock case 5 is equipped with a latch bolt 35, so the lower lock case 5 will be described below. The lock case 5 is incorporated inside the outer case 4. Since the outer case 4 is part of the door 2, in other words, the lock case 5 is incorporated inside the door 2. The lock case 5 (see Figures 4 and 5) is formed in a roughly rectangular parallelepiped shape and has an indoor side portion 21, an outdoor side portion 22, a bottom portion 23, a top portion 24, a door-edge side portion 25, and a hinge-side side portion 26. The deadbolt 27 is slidable in the left-right direction. An opening 25A is formed in the door-edge side portion 25 through which the deadbolt 27 extends and retracts. The driving force generated by the motor 34 is transmitted to the deadbolt 27 via the worm gear 32, idler gear 33, and deadbolt drive gear 28. 【0022】 The thumbturn gear 29 is meshed with the deadbolt drive gear 28. First detachable parts 31 are formed at both ends (indoor and outdoor ends) of the thumbturn gear shaft 30, which is located at the rotation center of the thumbturn gear 29. The first detachable parts 31 are recessed in the axial direction of the thumbturn gear shaft 30. The first detachable parts 31 are exposed from the indoor side surface 21 and the outdoor side surface 22. The thumbturn shaft 65, located at the rotation center of the thumbturn 64, is detachable from the first detachable part 31. In this embodiment, since the thumbturn 64 is located on the indoor side, the thumbturn shaft 65 is attached to and detached from the first detachable part 31 on the indoor side. By rotating the thumbturn 64, the thumbturn gear 29 and the deadbolt drive gear 28 rotate, causing the deadbolt 27 to extend and retract. 【0023】 [wiring] The wiring harness 6 is a bundle of multiple wires, including signal lines and power supply lines, and supplies control signals and power to the motor 34. One end of the wiring harness 6 is connected to the motor 34. The wiring harness 6 is arranged along the hinge-side portion 26 of the lock case 5. An opening 23A is formed in the bottom portion 23 of the lock case 5. A plug 43 (connector) is provided at the other end of the wiring harness 6. The plug 43 is connected to a receptacle 63 provided on the circuit board 61 inside the housing 8, which will be described later. Therefore, the wiring harness 6 has the length necessary to route from the motor 34 through the opening 23A to the circuit board 61. 【0024】 [Fixing fixture] The fastener 7 (see Figure 6) is made of a flexible material such as rubber. The fastener 7 has a strip-shaped main body 51 and protrusions 53 formed on both ends 52 in the longitudinal direction of the main body 51. The protrusions 53 are detachable from the first attachment / detachment part 31. An annular retaining part 54 is formed in the longitudinal center of the main body 51, penetrating in a direction intersecting the longitudinal direction. The space inside the retaining part 54 is large enough to insert the wiring 6, but is slightly smaller than the plug 43, so that the plug 43 does not come out of the retaining part 54 even if the fastener 7 is pulled while the wiring 6 is inserted into the retaining part 54. 【0025】 [Cabinet] A circuit board 61 is provided inside the housing 8 (see Figures 1, 2, 9, and 10). The circuit board 61 includes an integrated circuit (not shown) and supplies control signals and power to the motor 34 via wiring 6 according to the authentication results of a contactless IC card reader, keypad, biometric authentication device, etc. (not shown) provided in the housing 8 together with the circuit board 61. The circuit board 61 includes a receptacle 63 to which a plug 43 is connected. The housing 8 includes a second detachable part 62 to which the fixing device 7 can be attached and detached. The second detachable part 62 is, for example, a recess or through hole to which the protrusion 53 of the fixing device 7 can be attached and detached, and is provided inside the housing 8. 【0026】 [Procedure] In the factory that manufactures the lock case 5, the wiring 6 is secured using a fastener 7 at the end of the assembly process. Specifically, the worker inserts the wiring 6 into the holding part 54 of the fastener 7 and moves the fastener 7 to the vicinity of the plug 43 (see Figure 8). As mentioned above, the space inside the holding part 54 is formed to be slightly smaller than the plug 43, so even if the fastener 7 is pulled while the wiring 6 is inserted into the holding part 54, the plug 43 will not come out of the holding part 54. 【0027】 Next, the worker attaches the wiring 6 to the lock case 5 (see Figure 4(A)) before attaching the exterior side section 22. Specifically, the worker connects one end of the wiring 6 to the motor 34, then positions the wiring 6 along the hinge-side section 26 of the lock case 5, exposing the other end of the wiring 6 through the opening 23A. Next, the worker attaches the exterior side section 22 to the lock case 5 (see Figure 4(B)), folds the wiring 6 exposed through the opening 23A to the extent that it can be stored inside the lock case 5, positions the fastener 7 so that the holding section 54 faces the opening 23A (see Figure 7(D)), and attaches the protrusions 53 on both ends 52 of the fastener 7 to the first attachment / detachment sections 31 on the interior and exterior sides (see Figures 4(B), 5(A) to (C), and 7(B)). The assembled lock case 5 is then transported to the factory that manufactures the door 2. Ideally, the wiring 6 should be entirely housed inside the lock case 5, but a portion of the other end may be exposed outside the opening 23A. Even if a portion of the other end is exposed, since the lock case 5 is incorporated inside the door 2, the wiring 6 is also housed inside the door 2, and no damage to the wiring 6 occurs during transport. The housing 8 and handle 3 may be transported together with the door 2 to the manufacturing plant for the door 2, but they may also be stored separately in a warehouse and shipped directly to the installation site when the door 2 is installed. 【0028】 In the factory that manufactures door 2, workers assemble the lock case 5 into the outer case 4 (see Figure 7(A)). When the lock case 5 is assembled into the outer case 4, the end 52 of the fastener 7 attached to the first detachable part 31 on the interior side is exposed from the opening 11A of the outer case 4, and the end 52 of the fastener 7 attached to the first detachable part 31 on the exterior side is exposed from the opening 12A (not shown) of the outer case 4. Next, the workers assemble the outer case 4 into door 2, pack the door 2 with the outer case 4 assembled, and ship it. Note that the housing 8 and handle 3 are not attached to door 2 at the time of shipment. This allows door 2 to be shipped without any protrusions, reducing the burden of packing and transportation. 【0029】 When installing door 2, the worker removes both ends 52 of the fastener 7, which are exposed from the openings 11A and 12A of the outer case 4, from the first attachment / detachment part 31 (see Figures 7(C) and (D)). Next, the worker pulls out the fastener 7 from the opening 11A. At this time, the wiring 6 is pulled out along with the fastener 7. As mentioned above, the plug 43 does not come out of the holding part 54 even when the fastener 7 is pulled. 【0030】 In this embodiment, since the housing 8 is installed on the indoor side, the fastener 7 is pulled out on the indoor side. However, if the housing 8 is installed on the outdoor side, the fastener 7 is pulled out on the outdoor side. 【0031】 Next, the worker connects the plug 43 to the receptacle 63 (see Figures 9 and 10), attaches the protrusions 53 at both ends 52 of the fastener 7 to the second attachment / detachment part 62, and then attaches the housing 8 to the outer case 4. 【0032】 According to the lock device 1 of this embodiment described above, the lock device 1 comprises a lock case 5 incorporated inside the door 2, wiring 6 with one end connected to the lock case 5, a fastener 7 that holds a portion of the wiring 6, a first detachable part 31 provided on the side of the lock case 5, to which the fastener 7 can be attached and detached, and located at a position corresponding to openings 11A and 12A (not shown) formed on the side of the door 2, and a housing 8 attached to the side of the door 2 to which the other end of the wiring 6 is connected. With this configuration, the lock case 5 with the fastener 7 holding a portion of the wiring 6 attached to the first detachable part 31 is incorporated into the door 2, and the door 2 with the lock case 5 incorporated is shipped. When installing the door 2, after the fastener 7 is removed from the first detachable part 31, the wiring 6 is pulled out together with the fastener 7 from the openings 11A and 12A. Therefore, according to this embodiment, the wiring 6 housed in the lock case 5 incorporated inside the door 2 can be easily pulled out to the outside of the door 2. 【0033】 Furthermore, according to the lock device 1 of this embodiment, the fastener 7 is formed in a strip shape, and the first attachment / detachment portion 31 is provided on the indoor side portion 21 and the outdoor side portion 22 of the lock case 5, and both ends 52 of the fastener 7 are detachable. With this configuration, the door 2, in which the lock case 5 is assembled, is shipped with both ends 52 of the fastener 7, which holds a portion of the wiring 6, attached to the first attachment / detachment portion 31 on the indoor and outdoor sides. When installing the door 2, after both ends 52 of the fastener 7 are removed from the first attachment / detachment portion 31, the wiring 6 is pulled out together with the fastener 7 from the opening 11A, 12A corresponding to either of the first attachment / detachment portion 31, and the other end of the pulled-out wiring 6 is connected to the housing 8. Therefore, regardless of the direction in which the door 2 opens, the wiring 6 can be pulled out to either the indoor or outdoor side of the door 2. 【0034】 Furthermore, according to the lock device 1 of this embodiment, the lock case 5 has an operating member (thumbturn gear shaft 30) connected to an operating member (thumbturn 64) for operating the lock device 1, and the first attachment / detachment part 31 is provided on the operating member. Normally, the thumbturn gear shaft 30 has a recess formed therein to which the thumbturn shaft 65 is connected. In this embodiment, the fastener 7 is attached and detached by utilizing the recess of the thumbturn gear shaft 30 as the first attachment / detachment part 31, so there is no need to newly provide the first attachment / detachment part 31, and costs can be reduced. 【0035】 Furthermore, according to the locking device 1 of this embodiment, the housing 8 is provided with a second detachable part 62 from which a fixing device 7 holding the wiring 6 can be attached and detached. With this configuration, the wiring 6, whose other end is connected to the housing 8, can be easily fixed to the housing 8. 【0036】 The above embodiment may be modified as follows. 【0037】 In the above embodiment, the holding portion 54 of the fastener 7 is configured to hold a portion of the wiring 6, but the holding portion 54 is not essential. For example, the wiring 6 may be held by the fastener 7 using adhesive tape or the like. 【0038】 In the above embodiment, the first attachment / detachment portion 31 is provided at both ends of the thumbturn gear shaft 30, but the first attachment / detachment portion 31 may also be provided on the indoor side surface 21 and the outdoor side surface 22 of the lock case 5. 【0039】 In the above embodiment, an example was shown in which the second attachment / detachment portion 62 is a recess or through hole from which the protrusion 53 can be attached and detached. However, the second attachment / detachment portion 62 does not have to be configured to attach and detach the protrusion 53. For example, it may be configured to clamp the main body portion 51 of the fixing device 7, or to wrap around the main body portion 51 of the fixing device 7. 【0040】 While the above description of this embodiment describes the best mode of the locking device 1 according to the present invention, the present invention is not limited by the description and drawings of this embodiment. Furthermore, the components of the present invention described above can be replaced with existing components as appropriate, and various variations are possible, including combinations with other existing components.
