JP7813616B2 - Handles for fittings and locking/unlocking devices - Google Patents

Description

This disclosure relates to handles for building materials.

Conventionally, handles for fittings are known to be attached to locking/unlocking devices attached to shoji screens or doors installed at openings in buildings. When the locking/unlocking device is equipped with an electrical component that transmits handle position information, a battery may be stored in the handle. In structures that store a battery, a technology has been disclosed in which, when removing the cover member from the storage unit main body, the lock between the storage unit main body and the cover member is released using a release rod, and then the cover member is slid open relative to the storage unit main body (see, for example, Patent Document 1).

Japanese Patent Application Laid-Open No. 2008-258004

In the technology described in Patent Document 1, when removing the cover member from the storage unit body, it is cumbersome to use a release rod to release the lock between the storage unit body and the cover member. Furthermore, if the release rod is lost, it becomes impossible to release the lock. Meanwhile, there is a demand for a handle for fittings that is operated by rotation, with a structure that makes it difficult for the cover member to come off the storage unit body even when rotated or operated.

The objective of this disclosure is to provide a handle for fittings that prevents the cover member from coming off the storage unit body when rotated or operated, and allows the cover member to be easily removed from the storage unit body.

The present disclosure relates to a fitting handle provided in a locking/unlocking device installed in a shoji screen or door body installed at an opening in a building, the fitting handle comprising: a storage unit main body that is rotatably supported on a base fixed to the shoji screen or door body and that stores a power supply unit; and a cover member attached to the storage unit main body, the storage unit main body and the cover member being attached by a fitting engagement, the cover member being configured so that when the storage unit main body and the cover member are attached by a fitting engagement, the fitting engagement between the storage unit main body and the cover member is released when the outer surface of the cover member is pressed, and the fitting handle is slidable relative to the storage unit main body when the fitting between the storage unit main body and the cover member is released.

This figure shows the state in which, when the outer surface of the first lid portion is pressed, the inner end surface of the lid portion at the lid portion side step end of the first lid portion is moved in a direction that reduces the gap between it and the inner end surface of the case of the main body case. 10 is a cross-sectional view showing a state in which the outer surface of the first cover portion is pressed to release the engagement of the engagement protrusion. FIG.

One embodiment of the present disclosure will now be described. As shown in FIG. 1, a handle 1 as a fixture 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/close status notification device 100. The shoji screen open/close status 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.

The fixture in this embodiment is a sliding window 110 that fits into an opening formed in the wall of a building. The sliding window 110 comprises a rectangular frame body 120 made up of 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.

The inner shoji screen 130 is composed of a rectangular frame body 135 formed by an upper frame 131, a lower frame 132, and left and right vertical frames (inner joint frame 133), and a door end frame 134, and glass 136 fitted and fixed within 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, and left and right vertical frames (outer joint frame 143), and a door end frame 144, and glass 146 fitted and fixed within the frame body 145.

The inner shoji screen 130 and 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 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 outer shoji screen 140 in the front direction, the opening is closed or opened.

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.

The handle 1 is rotatably supported on 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 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 screen 140, thereby unlocking the door.

As shown in Figure 2, the handle 1 extends from a rotation axis J about which the handle 1 and crescent fitting 12 rotate together. When the handle 1 is rotated in the locked position shown in Figure 1, as shown in Figure 2, it extends upward from the rotation axis J about which the handle 1 and crescent fitting 12 rotate together in the direction in which the inner fitting frame 133 extends, covering the upper surface of the base 11. As shown in Figures 2 and 3, the handle 1 comprises 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.

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 Figure 2) is referred to as the X1 side, and the other side in the X direction (the lower side in Figure 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 3 side is referred to as the width direction H. The depth direction when the handle 1 is viewed from the first cover 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 rear side is referred to as the rear side D2.

The main body case 2 is formed to extend in the X direction. As shown in Figure 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 as a wall extending in the width direction H of the handle 1, closer to the X2 side in the X direction. As shown in Figures 3 and 4, the power supply case 5, power supply unit 6, and circuit board 7 are housed in the portion of the main body case 2 inside the outer peripheral wall portion 21 and the intermediate wall 23.

The power supply case 5 contains power supply units 6, each consisting of a size AA battery, which are arranged in a row in the X direction along which the handle 1 extends and connected in series. As shown in Figure 4, the power supply case 5 has a power supply case main body 51 formed with a U-shaped cross section, a holding claw 52, and a protruding rib 53.

As shown in Figure 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, arranged along the longitudinal direction of the base 51a between the X1 side wall 51b and the X2 side wall 51c.

The protruding rib 53 is formed in the center of the base 51a in the X direction, in the shape of a plate that protrudes from one end of the base 51a in the width direction H toward the near side D1. The protruding rib 53 restricts movement of the power supply unit 6 arranged in the power supply case main body 51 to one side in the width direction.

The holding claw 52 is formed in a plate shape at the center of the base 51a in the X direction, protruding toward the near side D1 from the end of the base 51a on the other side in the width direction H. The holding claw 52 is positioned 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 Figure 3, the holding claw 52 is positioned 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.

The power supply case 5 configured as described above has the power supply unit 6, which is placed in the power supply case body 51 and restricted on one side in the width direction H by the protruding rib 53, held from the other side in the width direction H by the holding claws 52.

Inside the main body case 2, a circuit board 7 (see Figure 4) is located on the rear side D2 of the power supply case 5. The circuit board 7, housed inside the main body case 2, is equipped 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 depending on the angle of the handle 1, and a communications IC (not shown). Power is supplied to the circuit board 7 from the power supply unit 6. The communications IC, for example, communicates wirelessly with the communications device R (see Figure 1), and uploads displacement information of the handle 1 in the X, Y, and Z axes from the acceleration sensor to an information processing device CO on the cloud CL, for example, via the Internet IN, as shown in Figure 1.

As shown in Figure 1, displacement information in the X, Y and Z axes from the acceleration sensor is calculated in the information processing device CO, which then calculates the building's tilt, the earthquake's strength, the rotation position of the steering wheel 1, whether glass has broken, etc. The calculated information is then sent to the terminal device TE via the Internet IN and displayed on the terminal device TE. The information processing device CO is composed of electronic devices 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 composed of electronic devices such as a personal computer, smartphone or tablet device.

As shown in Figure 2, the first lid portion 3 and the second lid portion 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 portion 3 and the second lid portion 4 are made of a resin material.

The first lid part 3 is located on the X1 side of the main 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 wall part 21 of the main case 2 so as to cover the power supply case 5, power supply part 6, and circuit board 7 (see Figure 4) housed in the main case 2. The outer edge of the first lid part 3 is attached to the outer edge of the X1 side of the main case 2. The first lid part 3 closes the internal space on the X1 side of the main case 2. The second lid part 4 is located on the X2 side of the main 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 case 2.

The structure for attaching the first lid portion 3 to the main body case 2 and the structure for removing the first lid portion 3 from the main body case 2 will be described.

First, we will explain the main case 2. As shown in Figure 3, the main case 2 has a case-side U-shaped wall portion 22 formed 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 case 2, and a locking hole 25 (locked portion) provided on the end of the main case 2 on the X1 side.

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 opens on the X2 side. The case side U-shaped wall 22 is formed as a wall extending in the depth direction D. A pair of case side walls 225 extending in the X direction are formed at 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 at 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.

As shown in FIG. 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 protruding further toward the first cover section 3 (near 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.

As shown in Figure 3, the case outer end surface 222 is formed narrowly 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. As shown in Figures 3 and 5, the case outer end surface 222 is formed in a surface that faces the first lid portion 3.

As shown in Figure 3, the case inner end surface 223 is formed narrowly inside the case side stepped end portion 221. The case inner end surface 223 is formed in a U-shape along the case outer end surface 222. As shown in Figure 5, the case inner end surface 223 is positioned at a position that protrudes further toward the first cover portion 3 than the case outer end surface 222, and is connected to the inside of the case outer end surface 222 via a step 224. As shown in Figures 3 and 5, the case inner end surface 223 is formed in a surface that faces the first cover portion 3.

The case-side stepped end 221 is formed in a stepped shape such that the inner case end surface 223 on the inner periphery protrudes further toward the first lid portion 3 than the outer case end surface 222 on the outer periphery.

As shown in Figures 3 and 6, the mating hole 24 is provided in the intermediate wall 23 extending in the width direction H at a position near the X2 side of the main case 2. The mating hole 24 is a rectangular opening that penetrates the intermediate wall 23 in the X direction. When the first cover 3 is attached to the main case 2, the mating protrusion 33 (described below) of the first cover 3 is fitted into the mating hole 24.

As shown in Figures 3 and 6, the locking hole 25 is formed at 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 case 2 and first cover portion 3 are attached by fitting, at the X1 side end of the first cover portion 3 opposite the X2 side end.

As shown in Figure 6, the locking hole 25 has 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 slopes 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 case 2, the locking protrusion 34 (described below) of the first cover 3 is locked into the locking hole 25.

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), multiple power supply pressing pieces 35 (pressing pieces), and multiple guide ribs 36 (protrusions).

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 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 rear side D2 (main case 2 side) end of the lid-side U-shaped wall 32 at the outer edge of the first lid 3.

As shown in Figures 3 and 5, the lid-side step end 321 has a lid-side outer end surface 322 (the outer surface of the cover member), a lid-side inner end surface 323 (the inner surface of the cover member) that is recessed further toward the top surface 31 (the front side D1 of the handle 1) than the lid-side outer end surface 322, and a step 324 (cover member-side step) that connects the lid-side outer end surface 322 and the lid-side inner end surface 323.

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

As shown in Figure 3, the lid inner end surface 323 is formed narrowly inside the lid-side stepped end portion 321 and is formed in a U-shape along the lid outer end surface 322. As shown in Figure 5, the lid inner end surface 323 is positioned recessed toward the top surface 31 relative to the lid outer end surface 322 and is connected to the inside of the lid outer end surface 322 via a step 324. As shown in Figures 3 and 5, the lid inner end surface 323 is formed in a surface that faces the main body case 2.

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

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

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 stepped end 221 of the main case 2 and the lid-side stepped end 321 of the first lid portion 3 are arranged opposite each other, and as shown in FIG. 5, the case-side stepped end 221 of the main case 2 and the lid-side stepped end 321 of the first lid portion 3 have abutting portions (the case outer end surface 222 of the case-side stepped end 221 and the 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 (the case inner end surface 223 of the case-side stepped end 221 and the lid inner end surface 323 of the lid-side stepped end 321).

As shown in FIG. 5 , when the outer edge of the first lid portion 3 is attached to the outer edge of the main case 2 and the outer surface of the first lid portion 3 is not being pressed, the lid portion outer end surface 322 of the lid portion-side stepped end portion 321 of the first lid portion 3 is positioned opposite and in contact with the case outer end surface 222 of the case-side stepped end portion 221 of the main case 2. The lid portion inner end surface 323 of the lid portion-side stepped end portion 321 of the first lid portion 3 is positioned opposite the case inner end surface 223 of the case-side stepped end portion 221 of the main case 2, with a gap S provided between them.

Furthermore, as shown in Figure 2, when the outer edge of the first lid part 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 part 3 is pressed, the first lid part 3 bends, as shown in Figure 8, and the lid part inner end surface 323 of the lid part side stepped end part 321 of the first lid part 3 faces the case inner end surface 223 of the case side stepped end part 221 of the main body case 2, and moves in a direction that reduces the gap S between it and the case inner end surface 223 of the main body case 2.

As shown in Figure 3, multiple power supply pressing pieces 35 are provided on the back (inner surface) of the top surface 31. The multiple power supply pressing pieces 35 press down on the power supply unit 6 when the first cover 3 is attached to the main case 2.

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

In this embodiment, the power supply unit 6 is restricted by the protruding rib 53 on one side of the power supply case 5 in the width direction H, and is held by the retaining claws 52 from the other side in the width direction H. When the first cover 3 is attached to the main case 2, the power supply unit 6 is held down by the multiple power supply retaining pieces 35, preventing it from coming off the power supply case 5. This prevents the power supply unit 6 from moving around when the handle 1 is rotated. Meanwhile, even when the first cover 3 is removed, the power supply unit 6 is still held by the protruding rib 53 and retaining claws 52 of the power supply case 5. This prevents the power supply unit 6 from falling 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.

In addition, 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 on 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. Instead, 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.

As shown in FIG. 3 , the multiple guide ribs 36 are formed to protrude from the back 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 of the lid-side U-shaped wall portion 32 in the width direction H are located. The multiple guide ribs 36 are arranged side by side in the X direction on both ends of the first lid portion 3 in the width direction H.

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 a position a predetermined distance inward from the edge of the first lid portion 3. The multiple guide ribs 36 are formed in a pin shape that protrudes toward the main body case 2 from the back surface of the top surface 31 at a position spaced inward in the width direction H from the pair of lid portion side walls 325.

The portion of the top surface 31 between each of the guide ribs 36 and the lid side wall 325 is connected to the lid side wall 325 by a reinforcing portion 36a. As shown in Figure 5, the tip of each of the guide ribs 36 on the main body case 2 side is positioned away from the inner surface 22a of the pair of case side walls 225 of the case-side U-shaped wall portion 22 of the main body case 2, toward the inside in the width direction H.

As shown in FIG. 5 , when the first lid portion 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 portion 22 of the main body case 2 are positioned between the tips of each of the multiple guide ribs 36 and the tips of the pair of lid side walls 325 of the lid-side U-shaped wall portion 32. As a result, when the first lid portion 3 slides in the X direction relative to the main body case 2, the multiple guide ribs 36 guide the movement of the first lid portion 3 by guiding the tips of the pair of case side walls 225 of the case-side U-shaped wall portion 22 of the main body case 2.

Furthermore, as shown in Figure 8, when the outer surface of the first lid portion 3 is pressed and the pair of lid portion side walls 325 bends 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 portion 22 of the main body case 2. By the tip of the guide rib 36 abutting against the inner surface 22a of the case side wall 225, the tip of the pair of lid portion side walls 325 of the lid portion side U-shaped wall portion 32 of the first lid portion 3 can be prevented from falling outward from the main body case 2.

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 X2 side end 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 with 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 front side D1 surface at the tip of the protruding piece 332.

When fitting the mating protrusion 33 into the mating hole 24 of the main case 2, as shown in Figure 7, the lid-side stepped end 321 of the first lid 3 is attached to the case-side stepped end 221 of the main case 2 so that the first lid 3 is positioned on the X1 side of the main case 2. Then, by sliding the first lid 3 from the X1 side to the X2 side, 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. This allows the main case 2 and the first lid 3 to be attached by mating.

To remove the mating protrusion 33 from the mating hole 24 of the main case 2, with the main case 2 and the first cover 3 attached by mating, the X2-side edge of the outer surface of the top panel 31 is pressed, causing the X2-side edge of the top panel 31 to bend and move toward the rear D2, as shown in FIG. 9 , and the mating protrusion 33 is moved toward the rear D2. This disengages the mating protrusion 33 from the mating hole 24 of the main case 2, and the main case 2 and the first cover 3 are no longer mated. 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.

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

As shown in FIG. 6 , the locking protrusion 34 has an inclined surface 341. The inclined surface 341 inclines 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 as a curved surface that convex outward. When the first cover 3 is attached to the main case 2, the inclined surface 341 engages with the inclined surface 251 of the locking hole 25 of the main case 2. As a result, when the first cover 3 is attached to the main case 2, the locking protrusion 34 engages with the locking hole 25 of the main 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 case 2.

Next, we will explain the procedure for attaching the first lid part 3 to the main body case 2 and the procedure for removing the first lid part 3 from the main body case 2.

When attaching the first lid 3 to the main case 2, as shown in Figure 7, the lid-side stepped end 321 of the first lid 3 is attached to the case-side stepped end 221 of the main case 2 so that the first lid 3 is positioned on the X1 side of the main case 2. In this state, the engagement protrusion 33 of the first lid 3 is positioned on the X1 side of the engagement hole 24 formed in the intermediate wall 23, disengaging the main case 2 from the first lid 3, allowing the first lid 3 to slide toward the X2 side relative to the main case 2.

In this state, by sliding the first cover 3 toward the X2 side, guided by multiple guide ribs 36 (see Figure 3), 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 into the locking hole 25. This allows the first cover 3 to be attached to the main case 2, as shown in Figures 2 and 6.

To remove the first lid 3 from the main case 2, from the state shown in Figure 2, the X2-side end portion of the top surface 31 of the first lid 3 is pushed toward the rear D2. As a result, as shown in Figure 8, the first lid 3 bends, and the lid-inner end surface 323 of the lid-side stepped end 321 of the first lid 3 faces the case-inner end surface 223 of the case-side stepped end 221 of the main case 2. This moves the gap S between the lid-inner end surface 323 and the case-inner end surface 223 of the main case 2 in a direction that reduces the gap. As a result, the pair of lid side walls 325 of the first lid 3 bend outward and are pushed outward in the width direction H. In this case, the tips of the guide ribs 36 abut against 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 tips of the guide ribs 36 abut against the inner surfaces 22a of the case side walls 225, preventing the tips of the pair of lid side walls 325 of the lid side U-wall portion 32 of the first lid portion 3 from falling outward from the case outer end surface 222 of the case side stepped end portion 221 of the main body case 2.

In this state, as shown in Figure 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 case 2, and the engagement protrusion 33 moves to the rear side D2 in conjunction with this. As a result, as shown in Figure 9, the engagement protrusion 33 disengages from the engagement hole 24. In this state, by sliding the first cover 3 toward the X1 side, the engagement protrusion 33 is removed from the engagement hole 24. In this way, the engagement protrusion 33 can be removed from the engagement hole 24 without the first cover 3 falling off the main case 2. Furthermore, at the X1-side end of the first cover 3, the locking protrusion 34 (see Figure 6) is removed from the locking hole 25. As shown in Figure 6, even if the first cover 3 is removed from the main case 2 in an angled position and the locking protrusion 34 is pulled out of the locking hole 25 in an angled position, the inclined surface 341 formed on the locking protrusion 34 prevents damage to the locking protrusion 34 and the locking hole 25. In this way, the first cover 3 can be easily removed from the main case 2.

The present embodiment described above provides the following advantages. In this embodiment, the handle 1 comprises 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 locking mechanism. The first lid 3 is configured so that, when the main case 2 and the first lid 3 are attached by a locking mechanism, the locking mechanism 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 locking mechanism 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 locking mechanism, the first lid 3 is unlikely to come off the main case 2 even when rotated or operated. Furthermore, because the locking mechanism 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.

In addition, this embodiment includes a power supply case 5 housed in the main body case 2 and in which the power supply unit 6 is placed. The power supply case 5 is provided with a retaining claw 52 that holds the power supply unit 6, and the back surface of the first cover 3 is provided with a power supply pressing piece 35 that holds the power supply unit 6. 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 retaining claw 52 of the power supply case 5. Therefore, even when the first cover 3 is removed with the handle 1 attached to the crescent lock 10, the power supply unit 6 will not fall, making it easy to replace the power supply unit 6.

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 as 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 if the outer surface of the first lid portion 3 is pressed.

As a result, when the first cover 3 slides in the X direction relative to the main case 2, the guide ribs 36 guide the tips of the pair of case side walls 225 of the case-side U-shaped wall portion 22 of the main case 2, thereby guiding the movement of the first cover 3. Furthermore, as shown in FIG. 8 , when the outer surface of the first cover 3 is pressed and the pair of cover side walls 325 bend outward, the tips of the guide ribs 36 abut against 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, thereby preventing the first cover 3 from falling off the main case 2.

In addition, in this embodiment, when the outer edge of the first lid portion 3 is attached to the outer edge of the main case 2, the case-side stepped end 221 of the main case 2 and the lid-side stepped end 321 of the first lid portion 3 are arranged opposite each other, and the case-side stepped end 221 of the main case 2 and the lid-side stepped end 321 of the first lid portion 3 have abutting portions (the case-exterior end surface 222 of the case-side stepped end 221 and the lid-exterior end surface 322 of the lid-side stepped end 321) and portions where they are separated from each other, forming a gap S (the case-interior end surface 223 of the case-side stepped end 221 and the lid-interior end surface 323 of the lid-side stepped end 321). As a result, when the outer surface of the first lid portion 3 is pressed, the gap S makes it easy to bend the first lid portion 3 toward the storage unit main body 2 by the amount of the gap S, making it easy to disengage the storage unit main body 2 and the first lid portion 3. This allows the first lid 3 to be easily removed from the main body case 2.

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

In addition, in this embodiment, the first cover 3 has a locking protrusion 34 that engages with and disengages from the locking hole 25 when attaching or detaching the first cover 3 to the main case 2, and the locking protrusion 34 has an inclined surface 341. This prevents damage to the locking protrusion 34 even if the locking protrusion 34 is removed from the locking hole 25 in an inclined state.
