[0008] An embodiment of the present disclosure will be described below. As shown in Fig. 1, a handle 1 as a fitting handle of the present disclosure is provided in a crescent lock 10 as a locking / unlocking device. The crescent lock 10 as a locking / unlocking device is provided in a shoji screen open / closed state notification device 100. The shoji screen open / closed state notification device 100 includes the crescent lock 10 as a locking / unlocking device, an information processing device CO on a cloud CL connected via the Internet IN, and a terminal device TE connected via the Internet IN and displaying information from the information processing device CO.

[0009] The fixture according to this embodiment is a sliding window 110 that is fitted into an opening formed in the wall of a building. The sliding window 110 comprises a frame body 120 that is framed in a rectangular shape by an upper frame 121, a lower frame 122, and left and right vertical frames 123, 124, and an inner shoji screen 130 (shoji screen) and an outer shoji screen 140 that are fitted into the frame body 120 so that they can be opened and closed.

[0010] The inner shoji screen 130 is composed of a rectangular frame body 135 formed by an upper frame 131, a lower frame 132, an inner joint frame 133 which are left and right vertical frames, and a door end frame 134, and glass 136 fitted and fixed into the frame body 135. The outer shoji screen 140 is composed of a rectangular frame body 145 formed by an upper frame 141, a lower frame 142, an outer joint frame 143 which are left and right vertical frames, and a door end frame 144, and glass 146 fitted and fixed into the frame body 145.

[0011] The inner shoji screen 130 and the outer shoji screen 140 are equipped with a crescent lock 10 for locking the door at the joint. Both the inner shoji screen 130 and the outer shoji screen 140 are sliding doors that can be opened and closed by sliding them in the front direction. In other words, by sliding the inner shoji screen 130 and the outer shoji screen 140 in the front direction, the opening is closed or opened.

[0012] As shown in Figures 1 to 3, the crescent lock 10 comprises a base 11 attached to the visible surface of the inner joint frame 133 on the outer screen 140 side, a handle 1 (a handle for fittings), and a crescent fitting 12 that rotates in conjunction with the handle 1 and engages with a crescent receiving fitting (not shown) fixed to the outer screen 140. A power supply unit U is mounted on the handle 1.

[0013] The handle 1 is rotatably supported relative to the base 11. When the handle 1 is rotated, the crescent fitting 12 engages with a crescent receiving fitting (not shown) fixed to the outer door screen 140, thereby locking the door. When the handle 1 is rotated, the crescent fitting 12 disengages from the crescent receiving fitting (not shown) fixed to the outer door screen 140, thereby unlocking the door.

[0014] As shown in FIG. 2, the handle 1 extends from a rotation axis J about which the handle 1 and the crescent fitting 12 rotate together. When the handle 1 is rotated to the locked position shown in FIG. 1, as shown in FIG. 2, the handle 1 extends upward from the rotation axis J about which the handle 1 and the crescent fitting 12 rotate together along the direction in which the inner fitting frame 133 extends, so as to cover the upper surface of the base 11. As shown in FIGS. 3 to 6, the handle 1 includes a main case 2 (storage section), a first lid 3 (cover member), a second lid 4, a power supply case 5, a power supply unit 6, a circuit board 7, and an LED lens 8. The main case 2 and the power supply case 5 constitute a power supply unit U. The power supply case 5 is stored in the main case 2. The power supply case 5 is equipped with a circuit board 7, an LED lens 8, and a harness 9. An acceleration sensor 71 and an LED 72 are mounted on the circuit board 7.

[0015] In the description of this embodiment, the direction in which the handle 1 extends when the handle 1 is locked is referred to as the X direction. In the X direction, one side (the upper side in FIG. 2) is referred to as the X1 side, and the other side in the X direction (the lower side in FIG. 2) is referred to as the X2 side. The width direction perpendicular to the X direction when the handle 1 is viewed from the first cover part 3 side is referred to as the width direction H. The depth direction when the handle 1 is viewed from the first cover part 3 side is referred to as the depth direction D. In the depth direction D, the front side is referred to as the front side D1, and the back side is referred to as the back side D2.

[0016] The main body case 2 is formed to extend in the X direction. As shown in Fig. 4, the main body case 2 has an outer peripheral wall portion 21 arranged on the outer edge of the main body case 2, and an intermediate wall 22. The intermediate wall 22 is formed in a wall shape extending in the width direction H of the handle 1, closer to the X2 side in the X direction. As shown in Figs. 4 to 6, the power supply case 5, the power supply unit 6, the circuit board 7, the LED lens 8, and the harness 9 are housed in the parts of the main body case 2 that are inside the outer peripheral wall portion 21 and the intermediate wall 22.

[0017] 5 and 7, the cross section of the power supply case 5 taken along the X direction is formed into a substantially U-shape. The power supply case 5 is equipped with a first terminal 51 (power supply terminal) for the power supply unit 6 that comes into contact with the positive terminal of the power supply unit 6, and a second terminal 52 (power supply terminal) for the power supply unit 6 that comes into contact with the negative terminal of the power supply unit 6. The power supply case 5 is equipped with power supply units 6 made up of AA dry cells that are arranged in a row in the X direction in which the handle 1 extends and connected in series.

[0018] The board 7 is a board for controlling the crescent lock 10 (locking / unlocking device). The board 7 is mounted on the power supply case 5. As shown in Figures 5 and 6, the board 7 is located inside the main body case 2 on the rear side D2 of the power supply case 5, and as shown in Figure 6, is attached to the power supply case 5 with screws 7a.

[0019] As shown in FIGS. 5 to 7, the board 7 is mounted with an acceleration sensor 71 (sensor) (see FIG. 7) that can detect acceleration in three or more axes (X-axis, Y-axis, and Z-axis), an LED 72 (light-emitting unit) that lights up during initial setup (when the power supply unit 6 is attached), and various ICs such as a communication IC (not shown). In this embodiment, the acceleration sensor 71 is mounted on the surface of the board 7 on the front side D1, as shown in FIG. 7. The LED 72 is mounted on the surface of the board 7 on the back side D2, as shown in FIG. 6. In this manner, the acceleration sensor 71 and the LED 72 are mounted in the power supply case 5.

[0020] The LED lens 8 is mounted on the power supply case 5. As shown in Figures 5 and 6, the LED lens 8 is attached to the rear side D2 of the power supply case 5. The LED lens 8 is disposed on one side of the board 7 in the width direction H on the rear side D2 of the power supply case 5.

[0021] The LED lens 8 diffuses light emitted from the LED 72 mounted on the substrate 7. The LED lens 8 is disposed in a through opening 23 formed in one side surface of the main body case 2 in the width direction H. This exposes the LED lens 8 to the outside of the handle 1. The through opening 23 is formed by penetrating one side surface of the main body case 2 in the width direction H, and extends a predetermined length in the X direction. In this way, the LED 72 (light-emitting portion) and the LED lens 8 are mounted in the power supply case 5.

[0022] The harness 9 has a first harness 91 that connects the first terminal 51 provided on the power supply case 5 to the board 7, and a second harness 92 that connects the second terminal 52 provided on the power supply case 5 to the board 7. The harness 9 is mounted on the power supply case 5.

[0023] Power is supplied to the substrate 7 from the power supply unit 6. The communication IC performs wireless communication with, for example, a communication device R (see FIG. 1), and uploads displacement information of the steering wheel 1 in the X, Y, and Z axis directions from the acceleration sensor 71 to an information processing device CO on the cloud CL via, for example, the Internet IN, as shown in FIG.

[0024] As shown in FIG. 1, the displacement information in the XYZ axis directions from the acceleration sensor 71 is calculated in the information processing device CO, which then calculates the inclination of the building, the strength of the earthquake, the rotation position of the steering wheel 1, the occurrence of glass breakage, etc. The calculated information is then transmitted to the terminal device TE via the Internet IN and displayed on the terminal device TE. The information processing device CO is configured by an electronic device such as an application server. The terminal device TE includes a monitor that displays information such as the rotation position of the steering wheel 1 calculated by the information processing device CO on the cloud CL, and is configured by an electronic device such as a personal computer, smartphone, tablet terminal, etc.

[0025] As shown in FIG. 2, the first cover 3 and the second cover 4 are attached to the front side D1 of the main body case 2 so as to cover the surface of the front side D1 of the handle 1. The first cover 3 is arranged on the X1 side of the main body case 2 in the X direction and extends in the X direction. The outer edge of the first cover 3 is attached to the outer edge of the main body case 2 on the X1 side. The second cover 4 is arranged on the X2 side of the main body case 2 in the X direction. The length of the second cover 4 in the X direction is shorter than the length of the first cover 3 in the X direction. The outer edge of the second cover 4 is attached to the outer edge of the main body case 2 on the X2 side.

[0026] The first lid part 3 is attached to the X1 side of the outer peripheral wall part 21 of the main body case 2 so as to cover the power supply case 5, power supply part 6, circuit board 7, LED lens 8, and harness 9 housed in the main body case 2. The first lid part 3 closes the internal space on the X1 side of the main body case 2.

[0027] In the above power supply unit U, the power supply case 5 in which the power supply unit 6 is placed is equipped with a control board 7 for the crescent lock 10, an acceleration sensor 71, power terminals (first terminal 51, second terminal 52), an LED 72, an LED lens 8 that transmits light from the LED 72, and a harness 9.

[0028] Therefore, the electrical components are integrated into the power supply unit U, forming a unit. This allows the crescent lock 10 to be easily made smarter by "changing the handle 1," by replacing only the handle 1, which includes the power supply unit U, while leaving the mechanical parts other than the handle 1 as they are. In this case, there is no need to perform additional processing on the handle 1, which is the attachment part, and it can be easily replaced with an existing part. This also helps reduce investment required to make the lock smarter.

[0029] Furthermore, because the electrical components are integrated into the power supply unit U, when applied to various locking / unlocking devices (for example, cam latches, cremone handles, thumb turns, etc.), installation can be easily achieved by simply providing the power supply unit U of the present disclosure, in which the electrical components are integrated, in the various locking / unlocking devices. This makes it easy to handle the electrical components of the handle 1. Furthermore, because the electrical components are integrated into the power supply unit U, the power supply unit U mounted on the handle 1 can be used for multiple purposes when applied to various locking / unlocking devices, which also helps reduce investment.

[0030] Although the preferred embodiments of the present disclosure have been described above, the present disclosure is not limited to the above-described embodiments and can be modified as appropriate.

[0031] For example, in this embodiment, the locking / unlocking device is fixed to the shoji screen, but this configuration is not limited to this. For example, the locking / unlocking device may be fixed to the door body. Also, the power supply unit U is configured to be attached to the operating portion of the crescent lock, but this configuration is not limited to this. The locking / unlocking device may be configured, for example, with a cam latch, a cremone handle, or a thumb turn, and the fitting handle may be attached to, for example, the operating portion of the cam latch, the operating portion of the cremone handle, or the operating portion of the thumb turn.
