DETAILED DESCRIPTION OF THE INVENTION

[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 and 2, 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 (door and fixture handle), 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.

[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 in the locked rotation position shown in Fig. 1, it extends upward from the rotation axis J about which the handle 1 and the crescent fitting 12 rotate together in the same direction as the inner fitting frame 133 extends, so as to cover the upper surface of the base 11, as shown in Fig. 2. As shown in Figs. 2 and 3, the handle 1 includes a main body case 2 (storage unit main body), a first lid 3 (cover member), a second lid 4, a power supply case 5, a power supply unit 6, and a 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. 3, 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 23. The intermediate wall 23 is formed in a wall shape extending in the width direction H of the handle 1, near the X2 side in the X direction. As shown in Figs. 3 and 4, the power supply case 5, the power supply unit 6, and the circuit board 7 are housed in the parts of the main body case 2 that are inside the outer peripheral wall portion 21 and the intermediate wall 23.

[0017] Power supply units 6, which are constituted by AA batteries, are arranged in a row and connected in series in the X direction along which the handle 1 extends in the power supply case 5. As shown in Fig. 4, the power supply case 5 has a power supply case main body 51 formed with a U-shaped cross section, holding claws 52, and protruding ribs 53.

[0018] 4, the power supply case body 51 has a base 51a extending in the X direction, an X1 side wall 51b, and an X2 side wall 51c. The power supply case body 51 has two power supply units 6 connected in series in the X direction, which are arranged along the longitudinal direction of the base 51a between the X1 side wall 51b and the X2 side wall 51c.

[0019] The protruding rib 53 is formed in a plate shape at the center of the base 51a in the X direction and protrudes toward the front side D1 from one end of the base 51a in the width direction H. The protruding rib 53 restricts movement of the power supply unit 6 arranged in the power supply case main body 51 toward one side in the width direction.

[0020] The holding claw 52 is formed in a plate shape at the center of the base 51a in the X direction and protrudes toward the front side D1 from the end of the base 51a on the other side in the width direction H. The holding claw 52 is arranged opposite the protruding rib 53. The holding claw 52 is formed in a claw shape with the tip 52a curved toward one side in the width direction H of the base 51a. As shown in FIG. 3 , the holding claw 52 is arranged along the curved surface of the power supply unit 6 housed in the power supply case main body 51, and holds the power supply unit 6, which is restricted on one side in the width direction H by the protruding rib 53, from the other side in the width direction H.

[0021] In the power supply case 5 configured as described above, the power supply unit 6 is disposed in the power supply case body 51 and is restricted on one side in the width direction H by the protruding rib 53, and is held from the other side in the width direction H by the holding claws 52.

[0022] Inside the main body case 2, a circuit board 7 (see FIG. 4) is arranged on the rear side D2 of the power supply case 5. The circuit board 7, housed inside the main body case 2, is mounted with various ICs, such as an acceleration sensor (not shown) capable of detecting acceleration in three or more axes (X-axis, Y-axis, and Z-axis), an LED that lights up according to the angle of the handlebars 1, and a communication IC (not shown). Power is supplied to the circuit board 7 from the power supply unit 6. The communication IC, for example, wirelessly communicates with a communication device R (see FIG. 1), and uploads displacement information of the handlebars 1 in the X, Y, and Z-axis directions from the acceleration sensor to an information processing device CO on the cloud CL, for example, via the Internet IN, as shown in FIG. 1.

[0023] As shown in FIG. 1, the displacement information in the XYZ axes directions from the acceleration sensor 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, for example, 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, for example, by an electronic device such as a personal computer, smartphone, or tablet terminal.

[0024] 2, the first lid part 3 and the second lid part 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 lid part 3 and the second lid part 4 are made of a resin material.

[0025] The first lid part 3 is disposed on the X1 side of the main body case 2 in the X direction and extends in the X direction. 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, and circuit board 7 (see FIG. 4) housed in the main body case 2. The outer edge of the first lid part 3 is attached to the outer edge of the X1 side of the main body case 2. The first lid part 3 closes the internal space on the X1 side of the main body case 2. The second lid part 4 is disposed on the X2 side of the main body case 2 in the X direction. The length of the second lid part 4 in the X direction is shorter than the length of the first lid part 3 in the X direction. The outer edge of the second lid part 4 is attached to the outer edge of the X2 side of the main body case 2.

[0026] The structure for attaching the first cover part 3 to the main body case 2 and the structure for removing the first cover part 3 from the main body case 2 will be described.

[0027] First, we will explain the main body case 2. As shown in Fig. 3, the main body case 2 has a case-side U-shaped wall portion 22 constituted by the X1-side portion of the aforementioned outer peripheral wall portion 21, a mating hole 24 provided in an intermediate wall 23 formed and extending in the width direction H near the X2 side of the main body case 2, and a locking hole 25 (locked portion) provided on the end side of the main body case 2 on the X1 side.

[0028] When viewed from the front side D1 of the handle 1, the case side U-shaped wall 22 is formed in a U-shape that is open on the X2 side. The case side U-shaped wall 22 is formed in a wall shape extending in the depth direction D. A pair of case side walls 225 extending in the X direction are formed on both ends of the case side U-shaped wall 22 in the width direction H. A stepped case side stepped end 221 (storage section side end) is formed on the end of the front side D1 (first lid section 3 side) of the case side U-shaped wall 22 at the outer edge of the main body case 2.

[0029] As shown in Figure 5, the case side step end 221 has a case outer end face 222 (outer surface of the storage section), a case inner end face 223 (inner surface of the storage section) that is positioned at a position protruding further toward the first cover section 3 (front side D1 of the handle 1) than the case outer end face 222, and a step 224 (storage section side step) that connects the case outer end face 222 and the case inner end face 223.

[0030] 3, the case outer end surface 222 is formed in a narrow shape on the outside of the case side stepped end portion 221. The case outer end surface 222 is formed in a U-shape along the outer edge of the X1 side portion of the main case 2. The case outer end surface 222 is formed in a plane facing the first cover part 3 side, as shown in FIGS. 3 and 5.

[0031] As shown in Fig. 3, case inner end surface 223 is formed in a narrow shape inside case side stepped end portion 221. Case inner end surface 223 is formed in a U-shape along case outer end surface 222. As shown in Fig. 5, case inner end surface 223 is disposed at a position that protrudes toward first cover 3 beyond case outer end surface 222, and is connected to the inside of case outer end surface 222 via step 224. As shown in Figs. 3 and 5, case inner end surface 223 is formed in a plane that faces first cover 3.

[0032] The case-side stepped end portion 221 is formed in a stepped shape such that the case inner end surface 223 on the inner circumferential side is positioned at a position that protrudes further toward the first lid portion 3 than the case outer end surface 222 on the outer circumferential side.

[0033] 3 and 6, the mating hole 24 is provided in the intermediate wall 23 extending in the width direction H at a position closer to the X2 side of the main body case 2. The mating hole 24 is configured as a rectangular opening that penetrates the intermediate wall 23 in the X direction. When the first cover part 3 is attached to the main body case 2, a mating protrusion 33 (described later) of the first cover part 3 is fitted into the mating hole 24.

[0034] 3 and 6, the locking hole 25 is formed in the X1 side end of the case side stepped end 221 of the case side U-shaped wall portion 22. The locking hole 25 is formed in a rectangular shape that penetrates the case side stepped end 221 in the X direction and extends in the width direction H. The locking hole 25 is formed in a part separate from the part where the main body case 2 and the first cover portion 3 are attached by fitting, at the X1 side end of the first cover portion 3 opposite the X2 side end.

[0035] As shown in Fig. 6, the locking hole 25 is provided with an inclined surface 251. The inclined surface 251 is formed by the inner surface of the front side D1 of the inner circumferential surface of the opening of the locking hole 25. The inclined surface 251 is inclined from the front side D1 to the rear side D2 in the depth direction D as it moves from the X1 side to the X2 side in the X direction. When the first cover 3 is attached to the main body case 2, a locking protrusion 34 (described later) of the first cover 3 is locked into the locking hole 25.

[0036] Next, we will explain the first lid part 3. As shown in Figure 3, the first lid part 3 has a top surface 31, a U-shaped lid part-side U-wall part 32, a mating protrusion 33, a locking protrusion 34 (locking part), a plurality of power supply pressing pieces 35 (pressing pieces), and a plurality of guide ribs 36 (protrusions).

[0037] The top surface 31 is formed in the shape of a plate extending in the X direction. The lid-side U-shaped wall 32 rises from the outer edge of the top surface 31 toward the main body case 2 and is formed in a U shape that is open on the X2 side. The lid-side U-shaped wall 32 protrudes from the outer edge of the top surface 31 toward the rear side D2. A pair of lid side walls 325 extending in the X direction are formed on both ends of the lid-side U-shaped wall 32 in the width direction H. A stepped lid-side stepped end 321 (cover member side end) is formed on the end of the lid-side U-shaped wall 32 on the rear side D2 side (main body case 2 side) at the outer edge of the first lid 3.

[0038] As shown in Figures 3 and 5, the lid portion side step end 321 has a lid portion outer end face 322 (outer surface of the cover member), a lid portion inner end face 323 (inner surface of the cover member) that is positioned in a recessed position closer to the top surface 31 (front side D1 of the handle 1) than the lid portion outer end face 322, and a step 324 (cover member side step) that connects the lid portion outer end face 322 and the lid portion inner end face 323.

[0039] Lid outer end surface 322 is formed narrowly on the outside of lid-side stepped end portion 321, and is formed in a U-shape along the outer edge of the X1 side of first lid 3. Lid outer end surface 322 is formed in a plane facing main body case 2, as shown in Figures 3 and 5 .

[0040] As shown in Fig. 3, lid inner end surface 323 is formed narrowly on the inside of lid side stepped end portion 321, and is formed in a U-shape along lid outer end surface 322. As shown in Fig. 5, lid inner end surface 323 is disposed at a position recessed toward top surface 31 relative to lid outer end surface 322, and is connected to the inside of lid outer end surface 322 via step 324. As shown in Figs. 3 and 5, lid inner end surface 323 is formed in a plane facing main body case 2.

[0041] The lid-side stepped end portion 321 is formed in a stepped shape such that the lid outer end surface 322 on the outer periphery protrudes further toward the main body case 2 than the lid inner end surface 323 on the inner periphery.

[0042] When the first lid portion 3 and main body case 2 configured as described above are in a state in which the outer edge of the first lid portion 3 is attached to the outer edge of the main body case 2, the first lid portion 3 can slide in the X direction as shown in Figure 7 by the portion extending in the X direction of the lid portion-side step end portion 321 of the lid portion-side U-shaped wall portion 32 of the first lid portion 3 moving in the X direction along the portion extending in the X direction of the case side step end portion 221 of the case side U-shaped wall portion 22 of the main body case 2.

[0043] Furthermore, when the outer edge of the first lid portion 3 is attached to the outer edge of the main case 2, the case side step end 221 of the main case 2 and the lid portion side step end 321 of the first lid portion 3 are arranged opposite each other, and the case side step end 221 of the main case 2 and the lid portion side step end 321 of the first lid portion 3 have portions where they abut each other (the case outer end surface 222 of the case side step end 221, the lid portion outer end surface 322 of the lid portion side step end 321) and portions where they are separated from each other and a gap S is formed (the case inner end surface 223 of the case side step end 221, the lid portion inner end surface 323 of the lid portion side step end 321), as shown in Figure 5.

[0044] 5, when the outer edge of first lid part 3 is attached to the outer edge of main body case 2 and the outer surface of first lid part 3 is not pressed, lid part outer end surface 322 of lid part-side stepped end part 321 of first lid part 3 is disposed facing and abutting against case outer end surface 222 of case side stepped end part 221 of main body case 2. Lid part inner end surface 323 of lid part-side stepped end part 321 of first lid part 3 is disposed facing case inner end surface 223 with a gap S provided between them and case inner end surface 223 of case side stepped end part 221 of main body case 2.

[0045] Furthermore, as shown in Figure 2, when the outer edge of the first lid portion 3 is attached to the outer edge of the main body case 2 and the outer surface of the X2 side end of the first lid portion 3 is pressed, the first lid portion 3 bends, as shown in Figure 8, and the lid portion inner end surface 323 of the lid portion side step end 321 of the first lid portion 3 moves in a direction that reduces the gap S between it and the case inner end surface 223 of the main body case 2, while facing the case inner end surface 223 of the case side step end 221 of the main body case 2.

[0046] 3, the plurality of power supply pressing pieces 35 are provided on the back (inner surface) of the top surface 31. The plurality of power supply pressing pieces 35 press down the power supply unit 6 when the first cover part 3 is attached to the main body case 2.

[0047] Each of the multiple power supply pressing pieces 35 protrudes from the back surface of the top surface 31 and has a pair of first pressing pieces 351 that press the X1 side portion of the power supply unit 6 on the X1 side, a pair of second pressing pieces 352 that press the X2 side portion of the power supply unit 6 on the X1 side, and a third pressing piece 353 that presses the X1 side portion of the power supply unit 6 on the X2 side.

[0048] In this embodiment, in the power supply case 5, the power supply unit 6 is restricted by the protruding rib 53 on one side in the width direction H and is held by the holding claws 52 from the other side in the width direction H, and the first cover 3 is attached to the main case 2, whereby the power supply unit 6 is held down by the multiple power supply holding pieces 35 and held so that the power supply unit 6 does not come off the power supply case 5. This prevents the power supply unit 6 from moving around when the handle 1 is rotated. On the other hand, even when the first cover 3 is removed, the power supply unit 6 is held by the protruding rib 53 and the holding claws 52 of the power supply case 5, so that the power supply unit 6 will not fall even if the first cover 3 is removed while the handle 1 is attached to the crescent lock 10, making it easy to replace the power supply unit 6.

[0049] Furthermore, no power supply pressing piece is provided on the X2 side end of the top surface 31. Therefore, even if the outer surface of the first cover part 3 is pressed at the X2 side end of the top surface 31, the power supply pressing piece 35 will not come into contact with the power supply unit 6, and when the outer surface of the X2 side end of the first cover part 3 is pressed, the X2 side end part of the first cover part 3 can bend and move towards the power supply unit 6.

[0050] 3, the guide ribs 36 are formed to protrude from the rear surface of the top surface 31 a predetermined distance inward in the width direction H from the positions where the pair of lid side walls 325 formed at both ends in the width direction H of the lid-side U-shaped wall portion 32 are disposed. The guide ribs 36 are provided side by side in the X direction on both end sides of the first lid portion 3 in the width direction H.

[0051] The multiple guide ribs 36 are formed on the back surface (inner surface) of the first lid portion 3, protruding toward the main body case 2 at positions a predetermined distance inward from the edge of the first lid portion 3. The multiple guide ribs 36 are formed in a pin shape protruding from the back surface of the top surface 31 toward the main body case 2 at positions spaced inward in the width direction H from the pair of lid portion side walls 325.

[0052] The portions of the guide ribs 36 on the top surface 31 side between the respective guide ribs 36 and the lid side wall 325 are connected to the lid side wall 325 by reinforcing portions 36a. The tip of each of the guide ribs 36 on the main body case 2 side is spaced apart inward in the width direction H from the inner surfaces 22a of the pair of case side walls 225 of the case-side U-shaped wall portion 22 of the main body case 2, as shown in FIG.

[0053] 5, when the first lid part 3 is attached to the main body case 2, the tips of the pair of case side walls 225 of the case-side U-shaped wall part 22 of the main body case 2 are disposed between the tip of each of the plurality of guide ribs 36 and the tips of the pair of lid side walls 325 of the lid-side U-shaped wall part 32. As a result, when the first lid part 3 slides in the X direction relative to the main body case 2, the plurality of guide ribs 36 guide the tip of the pair of case side walls 225 of the case-side U-shaped wall part 22 of the main body case 2, thereby guiding the movement of the first lid part 3.

[0054] 8, when the outer surface of the first lid part 3 is pressed and the pair of lid part side walls 325 is bent outward, the tip of the guide rib 36 abuts against the inner surface 22a of the pair of case side walls 225 of the case-side U-shaped wall part 22 of the main body case 2. The tip of the guide rib 36 abuts against the inner surface 22a of the case side wall 225, thereby preventing the tip of the pair of lid part side walls 325 of the lid-side U-shaped wall part 32 of the first lid part 3 from falling outward from the main body case 2.

[0055] As shown in Figures 3 and 6, the mating protrusion 33 is attached by mating with the mating hole 24 of the main body case 2. The mating protrusion 33 is provided at the end of the top surface 31 on the X2 side in the X direction. The mating protrusion 33 protrudes from the end of the X2 side of the back surface of the top surface 31 toward the main body case 2 in an L-shape in cross section. The mating protrusion 33 is formed to have a width in the width direction H. The mating protrusion 33 is configured to be elastically deformable. The mating protrusion 33 has a rising portion 331, a protruding piece 332 protruding from the rising portion 331 toward the X2 side, and a mating claw 333 formed on the surface of the protruding piece 332 on the front side D1 at the tip of the protruding piece 332.

[0056] When fitting the mating protrusion 33 into the mating hole 24 of the main case 2, as shown in Fig. 7, the cover-side stepped end 321 of the first cover 3 is attached to the case-side stepped end 221 of the main case 2 so that the first cover 3 is disposed on the X1 side relative to the main case 2, and then the first cover 3 is slid from the X1 side to the X2 side, whereby the mating protrusion 33 elastically deforms in the mating hole 24 of the main case 2 and is fitted into and attached to the mating hole 24. In this way, the main case 2 and the first cover 3 are attached by fitting.

[0057] To remove the mating protrusion 33 from the mating hole 24 of the casing 2, with the casing 2 and the first cover 3 attached by mating, the X2-side end portion of the outer surface of the top panel 31 is pressed, causing the X2-side end portion of the top panel 31 to bend and move toward the rear D2, as shown in FIG. 9 , and the mating protrusion 33 moves toward the rear D2. This disengages the mating hole 24 of the casing 2 from the mating protrusion 33, disengaging the casing 2 from the first cover 3. In this state, the first cover 3 can be slid toward the X1 side to remove the mating protrusion 33 from the mating hole 24.

[0058] The locking projection 34 is engaged with and disengaged from the locking hole 25 of the main body case 2 when the first lid portion 3 is attached to or detached from the main body case 2. As shown in Figures 3 and 6, the locking projection 34 is formed on the X1 side of the lid portion-side stepped end 321 of the lid portion-side U-shaped wall portion 32, protruding toward the X2 side from the end of the main body case 2 side of the outer wall 321a formed on the outside of the lid portion-side stepped end 321. The locking projection 34 is formed to have a width in the width direction H, as shown in Figure 3.

[0059] As shown in FIG. 6 , the locking protrusion 34 has an inclined surface 341. The inclined surface 341 is inclined from the front side D1 to the rear side D2 in the depth direction D as it moves from the X1 side to the X2 side in the X direction. The inclined surface 341 is formed in a curved shape that convexes outward. When the first cover part 3 is attached to the main body case 2, the inclined surface 341 is engaged with the inclined surface 251 of the locking hole 25 of the main body case 2. Thus, when the first cover part 3 is attached to the main body case 2, the locking protrusion 34 is engaged with the locking hole 25 of the main body case 2 with the inclined surface 341 of the locking protrusion 34 engaged with the inclined surface 251 of the locking hole 25 of the main body case 2.

[0060] Next, a procedure for attaching the first lid part 3 to the main body case 2 and a procedure for removing the first lid part 3 from the main body case 2 will be described.

[0061] 7, when attaching the first cover 3 to the main body case 2, the cover-side stepped end 321 of the first cover 3 is attached to the case-side stepped end 221 of the main body case 2 so that the first cover 3 is positioned on the X1 side of the main body case 2. In this state, the engagement protrusion 33 of the first cover 3 is positioned on the X1 side of the engagement hole 24 formed in the intermediate wall 23, and the main body case 2 and the first cover 3 are disengaged, allowing the first cover 3 to slide toward the X2 side relative to the main body case 2.

[0062] In this state, by sliding the first cover 3 guided by the multiple guide ribs 36 (see FIG. 3) toward the X2 side, the engagement protrusion 33 of the first cover 3 at the X2 side end of the first cover 3 is elastically deformed and engages with the engagement hole 24 of the main case 2. At the same time, the locking protrusion 34 at the X1 side end of the first cover 3 is locked in the locking hole 25. This allows the first cover 3 to be attached to the main case 2 as shown in FIGS. 2 and 6.

[0063] When removing the first cover 3 from the main case 2, the X2-side end portion of the top surface 31 of the first cover 3 is pushed toward the rear side D2 from the state shown in Fig. 2. As a result, as shown in Fig. 8, the first cover 3 is bent, and the cover-inner end surface 323 of the cover-side stepped end 321 of the first cover 3 faces the case-inner end surface 223 of the case-side stepped end 221 of the main case 2, and the gap S between the cover-inner end surface 323 and the case-inner end surface 223 of the main case 2 is moved in a direction that reduces the gap S between the cover-inner end surface 323 and the case-inner end surface 223 of the main case 2. As a result, the pair of cover side walls 325 of the first cover 3 are bent outward and pushed outward in the width direction H. In this case, the tips of the guide ribs 36 come into contact with the inner surfaces 22a of the pair of case side walls 225 of the case-side U-shaped wall portion 22 of the main case 2. The tip of the guide rib 36 abuts against the inner surface 22a of the case side wall 225, thereby preventing the tip of the pair of lid side walls 325 of the lid side U-shaped wall portion 32 of the first lid portion 3 from falling outward from the case outer end surface 222 of the case side step end portion 221 of the main body case 2.

[0064] In this state, as shown in Fig. 9, when the X2-side end of the top surface 31 of the first cover 3 is pressed, the top surface 31 moves toward the main body case 2, and in conjunction with this, the mating protrusion 33 moves to the rear side D2. As a result, as shown in Fig. 9, the mating protrusion 33 disengages from the mating hole 24. In this state, by sliding the first cover 3 toward the X1 side, the mating protrusion 33 is removed from the mating hole 24. In this way, the mating protrusion 33 can be removed from the mating hole 24 without the first cover 3 falling off the main body case 2. Furthermore, at the X1-side end of the first cover 3, the locking protrusion 34 (see Fig. 6) is removed from the locking hole 25. 6, even if first cover 3 is removed from main body case 2 in an inclined state and locking protrusion 34 is pulled out of locking hole 25 in an inclined state, locking protrusion 34 has inclined surface 341, which prevents damage to locking protrusion 34 and locking hole 25. In this way, first cover 3 can be easily removed from main body case 2.

[0065] The above-described embodiment provides the following advantages. In this embodiment, the handle 1 includes a main case 2 that houses the power supply unit 6 and a first lid 3 that is attached to the main case 2. The main case 2 and the first lid 3 are attached by a fitting. The first lid 3 is configured so that, when the main case 2 and the first lid 3 are attached by a fitting, the fitting between the main case 2 and the first lid 3 is released by pressing the outer surface of the first lid 3. The first lid 3 is slidable relative to the main case 2 when the fitting between the main case 2 and the first lid 3 is released. As a result, because the main case 2 and the first lid 3 are attached by a fitting, the first lid 3 is unlikely to come off the main case 2 even when rotated or operated. Furthermore, because the fitting between the storage unit main body 2 and the first lid 3 is released by pressing the outer surface of the first lid 3, the first lid 3 can be easily removed from the main case 2.

[0066] Furthermore, in this embodiment, the device is provided with a power supply case 5 that is housed in the main body case 2 and in which the power supply unit 6 is disposed, and the power supply case 5 is provided with a holding claw 52 that holds the power supply unit 6, and a power supply pressing piece 35 that holds the power supply unit 6 is provided on the back surface of the first cover 3. This prevents the power supply unit 6 from moving around when the handle 1 is rotated. On the other hand, even when the first cover 3 is removed, the power supply unit 6 is held by the protruding rib 53 and holding claw 52 of the power supply case 5, so that the power supply unit 6 will not fall even when the first cover 3 is removed with the handle 1 attached to the crescent lock 10, making it easy to replace the power supply unit 6.

[0067] In addition, in this embodiment, a guide rib 36 is provided on the back surface of the first lid portion 3, protruding toward the main body case 2 at a position a predetermined distance inward from the edge of the first lid portion 3.The guide rib 36 guides the movement of the first lid portion 3 when it slides relative to the main body case 2, and also prevents the first lid portion 3 from falling off the main body case 2 when the outer surface of the first lid portion 3 is pressed.

[0068] As a result, when first cover 3 slides in the X direction relative to main case 2, guide rib 36 guides the tips of the pair of case side walls 225 of case-side U-shaped wall portion 22 of main case 2, thereby guiding the movement of first cover 3. Furthermore, as shown in Figure 8, when the outer surface of first cover 3 is pressed and the pair of cover side walls 325 are bent outward, the tips of guide rib 36 come into contact with inner surfaces 22a of the pair of case side walls 225 of case-side U-shaped wall portion 22 of main case 2, thereby preventing first cover 3 from falling off from main case 2.

[0069] Furthermore, in this embodiment, when the outer edge of the first lid part 3 is attached to the outer edge of the main body case 2, the case-side stepped end 221 of the main body case 2 and the lid-side stepped end 321 of the first lid part 3 are arranged opposite each other, and the case-side stepped end 221 of the main body case 2 and the lid-side stepped end 321 of the first lid part 3 have portions where they abut (a case outer end surface 222 of the case-side stepped end 221 and a lid outer end surface 322 of the lid-side stepped end 321) and portions where they are separated from each other, forming a gap S (a case inner end surface 223 of the case-side stepped end 221 and a lid inner end surface 323 of the lid-side stepped end 321). As a result, when the outer surface of the first lid part 3 is pressed due to the gap S, the first lid part 3 is easily bent toward the storage part main body 2 by the amount of the gap S, making it easy to disengage the storage part main body 2 and the first lid part 3 from each other. Therefore, the first cover part 3 can be easily removed from the main body case 2.

[0070] Furthermore, in this embodiment, when the outer edge of first lid 3 is attached to the outer edge of main body case 2 and the outer surface of first lid 3 is pressed, lid inner end surface 323 moves in a direction that reduces gap S between lid inner end surface 323 and case inner end surface 223 while facing lid inner end surface 223. As a result, when the outer surface of first lid 3 is pressed, gap S makes it even easier to disengage storage unit main body 2 and first lid 3. This makes it even easier to remove first lid 3 from main body case 2.

[0071] Furthermore, in this embodiment, first cover 3 has locking protrusion 34 that is engaged with and disengaged from locking hole 25 when first cover 3 is attached to or detached from main body case 2, and locking protrusion 34 has inclined surface 341. This prevents locking protrusion 34 from being damaged even if locking protrusion 34 is pulled out of locking hole 25 in an inclined state.
