  Next, the battery accommodating device 11 will be described with reference to FIGS. 2, 3, and 6. In the following description, the direction from the inclined surface portion 25a of the cover 25 toward the indoor side wall surface 2b (direction connecting the indoor side and the outdoor side of the door 2) is also referred to as “depth direction”, and the front side is referred to as “back side”. "And the rear side is also called" front side ".

  The battery accommodating device 11 includes four batteries 60 and a cartridge 61 that holds each battery 60 in a vertical direction. In the present embodiment, a cylindrical dry battery is used as the battery 60.

  The cartridge 61 is accommodated in a power supply space S2 (in the power supply recess 14a) formed in the lower indoor side pedestal 14 of the indoor side handle 3. The cartridge 61 has a cartridge main body 62 having a main appearance, and a plurality of battery holding portions 63 arranged in parallel in the depth direction so as to hold four batteries 60 in the cartridge main body 62. .

  The cartridge main body 62 is integrally formed of an insulating resin material in a substantially box shape with the front side (inner side) open. On both upper and lower end surfaces of the cartridge main body 62, a step portion 62a is formed approximately in the middle in the front-rear direction, and the back side is lowered by one step. A mounting piece 62b extending upward is provided at the front of the upper end surface of the cartridge body 62, and the mounting piece 62b is fixed in the power supply recess 14a by a fixing screw B8. The cartridge body 62 may be fixed to the bottom surface of the power supply recess 14a. Further, the fixing means is not limited to screws, and may be fixed using, for example, an adhesive.

  In the cartridge 61, two battery holding parts 63 are arranged side by side in the depth direction. Hereinafter, for convenience of explanation, the back side is referred to as a first holding unit 64 and the front side is referred to as a second holding unit 65 (see FIG. 6).

  Two batteries 60 are held in the first holding part 64 and the second holding part 65 side by side, respectively. In other words, the four batteries 60 are arranged in the battery holding portion 63 in a two-row by two-column lattice pattern in front, rear, left, and right in a plan view. Steps are formed on the upper and lower portions between the first holding portion 36 and the second holding portion 37 in correspondence with the stepped portion 62a. Accordingly, the second holding portion 37 is disposed at a position higher than the first holding portion 36 (toward the indoor grip 15).

  As described above, the power supply space S2 is formed so as to be constricted in the front-rear direction (depth direction) from the upper side to the lower side. In order to correspond to the shape of the power supply space S2, the cartridge 61 (cartridge main body 62) is formed such that the holding portions 64 and 65 are displaced from each other and the lower end side is shortened (narrow) in the front-rear direction.

  Two coil-shaped negative electrode connection terminals 66 made of a conductive material such as metal are juxtaposed in the left-right direction at the lower ends of the first holding part 64 and the second holding part 65. Similarly, two plate spring-like positive electrode connection terminals 67 made of a conductive material such as metal are juxtaposed in the left-right direction at the upper ends of the first holding part 64 and the second holding part 65, respectively. Each negative electrode connection terminal 66 is in contact with the negative electrode 60 a of each battery 60 held in each holding part 64, 65, and each positive electrode connection terminal 67 is connected to the positive electrode of each battery 60 held in each holding part 64, 65. It contacts the electrode 60b.

  Although not shown in the drawings, lead metal fittings are extended in the vertical direction on the left and right outer surfaces of the cartridge main body 62, respectively. Each lead metal fitting, each negative electrode connection terminal 66 and each positive electrode connection terminal 67 are electrically connected so as to form an appropriate electric circuit. Further, from the cartridge main body 62, a power cable 68 connected to the terminals 66, 67 and the like extends.

  A power plug 68 a is attached to the distal end portion of the power cable 68. The power plug 68a is accommodated in the connection space S6 at the lower end of the lower chamber side pedestal 14 (below the thumb turn opening 3b). The connection space S6 is covered with a harness cover 14c.

  The power socket 59 attached to the harness 58 described above passes through the door 2 and is accommodated in the connection space S6. The power plug 68a is connected to the power socket 59, and the battery accommodating device 11 supplies power to the locking / unlocking operation device 8, the main electric lock 9, the sub electric lock 10 and the like via the power cable 68 and the harness 58. .

  Next, the operation of the electric lock system 1 will be described with reference to FIG. It is assumed that power is supplied from the battery housing device 11 to the locking / unlocking operation device 8 and the electric locks 9 and 10.

  A person (user) who wants to enter the room from outside the room pushes the push button 51 and then holds the IC card 100 over the leader board 52. Then, communication is performed between the IC card 100 and the reader substrate 52, and the authentication information of the IC card 100 is read by the reader substrate 52. The control circuit of the reader substrate 52 determines whether or not the read authentication information matches the specific authentication information stored in advance. As a result, when it is determined that they match, the unlock signal is output from the leader board 52 (control circuit) to the main electric lock 9, and the main electric lock 9 is unlocked. In conjunction with the unlocking of the main electric lock 9, an unlock signal is output from the reader substrate 52, and the sub electric lock 10 is unlocked. On the other hand, if it is determined that they do not match, the unlock signal from the leader board 52 is not transmitted, and the main electric lock 9 is not unlocked.

  As another unlocking method, when the person who wants to enter the room from outside the room has the portable key 101, the electric locks 9 and 10 are unlocked by pressing the push button 51. Specifically, push button 51 pressing information is transmitted to the control circuit of the reader substrate 52, and the result of wireless communication between the portable key 101 and the antenna substrate 53 is transmitted to the control circuit of the reader substrate 52. . The control circuit determines whether or not the communication information (authentication information) with the portable key 101 matches the specific authentication information stored in advance, and according to the determination result, each electric lock 9, Ten unlocks are performed (or no unlock is performed).

  As described above, since the locking / unlocking operation device 8 is built in the outdoor grip 32, the user can easily perform the locking / unlocking operation on the locking / unlocking operation device 8.

  For example, when the locking / unlocking operation device 8 does not operate due to insufficient power of the battery 60, the user uses the mechanical keys by removing the pair of upper and lower cylinder covers 30b, 31b to expose the cylinders 9c, 10c. Thus, the electric locks 9 and 10 can be locked and unlocked. As described above, in the normal state, the cylinder covers 30b and 31b cover the cylinders 9c and 10c to form the appearance of the outdoor handle 5 having a sense of unity. On the other hand, when the situation which cannot drive each electric lock 9 and 10 arises, the user can lock / unlock each electric lock 9 and 10 easily by manual operation.

  Next, with reference to FIG. 6, the replacement | exchange operation | work of the battery 60 of the battery accommodating apparatus 11 is demonstrated.

As a result, the two batteries 60 held by the first holding part 64 are exposed. Subsequently, the worker removes each battery 60 held by the first holding unit 64 from the back side toward the front side while pushing down the battery 60 slightly downward.

  Next, the new batteries 60 (two) are attached to the first holding portion 64 while being pushed down from the upper front side toward the lower rear side. At this time, since there is a step (stepped portion 62 a) at the top, a space is formed on the front side of the first holding portion 64. Thereby, the operator can efficiently attach and detach each battery 60 to / from the first holding part 64 on the back side. Subsequently, similarly, new batteries 60 (two) are attached to the second holding portion 65.

  Finally, the operator attaches the cover 20 to the lower chamber side pedestal 14. In this state, the cushion seal 26 of the cover 20 is in close contact with the front side of the cartridge 61 (cartridge main body 62) (see FIG. 2). Thus, the replacement work of the battery 60 is completed.
