Summary of the Invention
Problems to be Solved by the Invention
[0005] As shown in Patent Document 1, when waterproofing is not required, the power outlet is provided in an exposed state. However, in this case, since the power outlet (connection source) is in an open state, it is possible to pull out the connection destination during use and connect another electrical device arbitrarily.
[0006] Furthermore, if a power outlet is housed inside the enclosure, the door must be left open to allow the power cable to pass through the gap between the enclosure and the door. In this case as well, since the door can be opened freely, the power outlet is exposed. Consequently, it was possible to connect other electrical devices without permission. [Means for solving the problem]
[0007] A housing box that solves the above problems is a housing box that houses a connection source inside, and is equipped with a door, the door being provided with a small window of a size that allows a long object to be connected to the connection source to be inserted through, a closing member that closes the small window, and a closing maintenance member that maintains the closing of the small window by the closing member from the inside.
[0008] Furthermore, a door that solves the above problems is a door that opens and closes an opening in a space in which a connection source is located inside, and is provided with a small window having a size that allows a long object connected to the connection source to pass through, a closing member that closes the small window, and a closing maintenance member that maintains the closing of the small window by the closing member from the inside. [Effects of the Invention]
[0009] According to this disclosure, the connection source and destination can be connected and used without leaving the door open. [Brief explanation of the drawing]

[Figure 6] This is a front view of the main part of the underside of the lid used for the storage box in the modified example. [Modes for carrying out the invention]
[0011] Below, an embodiment of the storage box and door will be described using Figures 1 to 5. Figure 1 is a perspective view of the main part of the wall on which the storage box is provided in this embodiment, and Figures 2 and 3 are a plan cross-sectional view (cross-sectional view) and a longitudinal cross-sectional view of the storage box, respectively. Figure 4 is a front view of the underside of the lid used for the storage box.
[0012] As shown in Figure 1, a roughly rectangular space 11 is formed in the wall 10 of the building. This space 11 is open on one side of the wall 10. A roughly rectangular storage box 20 is housed inside the space 11. This storage box 20 is equipped with a door 30 that is provided in the part corresponding to the opening of the space 11.
[0013] The storage box 20 comprises a storage member 21, a bottom member 22 that forms the bottom surface, side members 23 and 24 that form both sides, and a top member 25 that forms the top surface. As shown in Figures 2 and 3, the storage member 21 is composed of multiple plate-like members and partitions a roughly rectangular parallelepiped-shaped space with an inclined bottom surface. Recesses are formed at the ends of the side members 23, 24 and the top member 25 of the storage member 21 that face the door 30, in order to accommodate the end of the door 30. The bottom surface of the storage member 21 is inclined so that the side facing the door 30 (front side) is lower.
[0014] As shown in Figure 2, a through-hole 24h is formed in the side member 24 of the housing member 21. This through-hole 24h communicates with a hole 10h formed in the wall 10. The power cable 27k of the power outlet 27, which serves as the connection source, is housed in these through-holes 24h and 10h. Furthermore, a recess 24a is formed in the central part of the side member 24 of the housing member 21.
[0015] In the housing member 21, a pair (two) of hook portions 28a and 28b are provided on the surface on the opposite side (the back side) of the door 30. The hook portions 28a and 28b are members for hooking the cable of an electric device at the connection end connected to the power outlet or the power cable 27k.
[0016] (Configuration of the door 30) As shown in FIG. 4, the door 30 includes a substantially square main body portion 30F. The main body portion 30F includes an outer peripheral portion formed in a U-shape by folding back the end portions of the outer periphery of the plate-like member. Bearing members 31 and 32 are fixed to the upper and lower ends on one end side (the side member 23 side) where the plate-like member of the main body portion 30F is folded back. A shaft A1 having its upper end fixed to the upper surface member 25 is rotatably supported by the bearing member 31. Also, a shaft A2 having its lower end fixed to the bottom surface member 22 is rotatably supported by the bearing member 32. When the bearing members 31 and 32 rotate with respect to the shafts A1 and A2, the door 30 opens and closes with respect to the housing member 21 of the housing box 20.
[0017] A key member 33 is provided at the center of the other end side (the side member 24 side) of the main body portion 30F of the door 30. The key member 33 includes a keyhole 33a at the center and a locking plate 33s having a rectangular plate shape. By inserting a key into the keyhole 33a of the key member 33, the locking plate 33s can be rotated.
[0018] <000009I>Then, as shown in FIG. 2, when the tip of the locking plate 33s is accommodated in the recess 24a of the side member 24 in a state where the locking plate 33s extends in the horizontal direction, the position of the door 30 is fixed. Thereby, the door 30 is in a closed state.
[0019] As shown in FIGS. 3 and 4, an opening serving as a small window 35 is provided at the center of the lower end of the door 30. The small window 35 includes a closing member 40 for closing the small window 35. Furthermore, the door 30 includes a mounting member 38 made of a magnetic material such as iron above the small window 35, and positioning members 36a and 36b on the left and right sides of the small window 35, respectively. The mounting member 38 and the positioning members 36a and 36b have the same width as the width of the closing member 40. Further, screw holes (not shown) are formed in the positioning members 36a and 36b on the side of the mounting member 38.
[0020] Both sides of the hinge 39 are fixed to the mounting member 38 and the closing member 40, respectively. The hinge 39 moves the closing member 40 rotatably with respect to the mounting member 38. A magnet 45 as an opening-maintaining member is fixed to the lower end of the closing member 40.
[0021] Furthermore, the closing member 40 includes a plate-shaped locking plate 41. This locking plate 41 abuts against the surfaces on the back side (opposite to the main body portion 30F of the door 30) of the positioning members 36a and 36b. One screw hole is formed at each of both ends of this locking plate 41. Each screw hole is provided at a position that aligns with the screw holes of the positioning members 36a and 36b. Then, screws 37a and 37b are screwed into the aligned screw holes of the locking plate 41 and the positioning members 36a and 36b. Here, the locking plate 41 and the screws 37a and 37b function as closing-maintaining members that maintain the closed state of the small window 35 from the inner side by the closing member 40.
[0022] (Usage method) Next, the usage method of the storage box 20 having the above-described configuration will be described using FIG. 5. For example, assume a case where an electric device is used in a hall or a square near the wall 10. Here, assume a case where the power plug of the cord reel 50 is plugged into the power outlet 27 of the storage box 20 for use as an electric device.
[0023] As shown in FIG. 1, before use, since the locking plate 33s of the door 30 is locked to the recess 24a, the door 30 is closed. Furthermore, as shown in Figure 2, the locking plate 41 of the closing member 40 is fixed to the positioning members 36a and 36b with screws 37a and 37b to close the small window 35. Therefore, the closing member 40 closes the small window 35.
[0024] Then, as shown in Figure 4, when using the lock, the key is inserted into the keyhole 33a of the lock member 33 and then rotated in the release direction R1. This causes the locking plate 33s to disengage from the recess 24a. By pulling the door 30 towards the user, the bearing members 31 and 32 rotate around axes A1 and A2, thereby opening the door 30.
[0025] Next, as shown in Figure 3, after removing screws 37a and 37b, the closing member 40 is rotated around the axis of the hinge 39. This opens the small window 35 that was previously closed by the closing member 40. Then, the magnet 45 of the closing member 40 is attracted to the mounting member 38. This keeps the small window 35 open.
[0026] Next, as shown in Figure 5, the power plug of the cord reel 50 is plugged into the power outlet 27. Furthermore, the long cable 51 of the cord reel 50 is positioned to pass through the small window 35.
[0027] Then, the door 30 is closed, and the key is inserted into the keyhole 33a of the locking member 33 and rotated in the locking direction (the opposite direction to the unlocking direction R1 in Figure 4). As a result, as shown in Figure 5, the door 30 is locked while the small window 35 through which the cable 51 of the cord reel 50 is inserted is open.
[0028] (Effect of the embodiment) The screws 37a and 37b that maintain the closed state of the small window 35 in the door 30 of the storage box 20 are located inside the storage box 20, so the small window 35 cannot be opened unless the door 30 is unlocked. Also, the cable 51 can be pulled out through the small window 35 while the door 30 remains locked.
[0029] (Effects of the embodiment) (1) In this embodiment, the housing box 20 containing the power outlet 27 is built into the wall 10. The housing box 20 has a door 30 with a small window 35. The door 30 has a closing member 40 that closes the small window 35, and a locking plate 41 and screws 37a, 37b for maintaining the closed state of the small window 35 by the closing member 40 from the inside of the door 30. This makes it possible to maintain the closed state of the closing member 40.
[0030] (2) In this embodiment, after removing the screws 37a and 37b, the closing member 40 that closes the small window 35 rotates to open the small window 35. In this case, the magnet 45 attached to the closing member 40 is attracted to the mounting member 38. This makes it possible to maintain the open state of the small window 35 that was closed by the closing member 40.
[0031] (3) In this embodiment, the mounting member 38 provided above the closing member 40 has the same width as the closing member 40. As a result, when the closing member 40 is rotated to open the small window 35, it is attracted to the mounting member 38 in a position where the magnet 45 is vertical. Therefore, the magnet 45 is attracted to the mounting member 38 with its entire surface, and the closing member 40 can be firmly supported.
[0032] (4) In this embodiment, the positioning members 36a and 36b provided on the left and right sides have the same width as the closing member 40. This allows the locking plate 41 that closes the closing member 40 to be attached using screws 37a and 37b.
[0033] (5) In this embodiment, a small window 35 is provided at the lower end of the door 30. As a result, when the door 30 is open, the small window 35 is recessed, so the cable 51 can be easily placed in the small window 35.
[0034] This embodiment can be implemented with the following modifications. This embodiment and the following modifications can be combined with each other to the extent that they do not contradict each other technically. In the above embodiment, a closing member 40 is provided to close the small window 35. The area to be opened may be changed by dividing the closing member 40 that closes the small window 35 into multiple parts.
[0035] For example, as shown in Figure 6, the small window 35 is closed with closing members 61 and 62. These closing members 61 and 62 are sized to divide the width of the closing member 40. Each closing member 61 and 62 functions as a first member that opens a first region of the small window 35 and a second member that opens a second region connected to the first region. Each closing member 61 and 62 has one side of a hinge 63 and 64 fixed to it. The other side of the hinge 63 and 64 is attached to the mounting member 38. Magnets 65 and 66 are provided on the back surface of each closing member 61 and 62.
[0036] To open a first area of the first area of a portion of the small window 35, half of the small window 35 is opened by rotating one of the closing members 61 or 62. To open a second area that is larger than the first area, the entire small window 35, including the first and second areas, is opened by rotating both the closing members 61 and 62.
[0037] In the above embodiment, the closing member 40 that closes the small window 35 is rotated by the hinge 39 to open the small window 35. Alternatively, the closing member that closes the small window may be a member that opens by sliding. For example, a sliding plate the size of the small window 35 can be fixed to the back of the door with a magnet or the like. The small window 35 can then be opened by sliding this sliding plate. The sliding plate in this shifted position can then be fixed with a magnet.
[0038] Furthermore, the closing maintenance member that maintains the closed state of the small window 35 from the inside is not limited to the locking plate 41 and screws 37a, 37b. For example, the closing member may be fixed with a magnet or the like to maintain the closed state of the small window.
[0039] In the above embodiment, a mounting member 38 with the same width as the closing member 40 is provided above the small window 35. When the small window 35 is opened, the magnet 45 of the closing member 40 is attracted to the mounting member 38. The opening maintenance member for maintaining the open state of the small window 35 by the closing member 40 is not limited to the magnet 45 attracted to the mounting member 38. For example, the mounting member may be omitted and the magnet may be directly attracted to the main body, or the closing member may be fixed to the main body of the door with screws or the like.
[0040] In the above embodiment, positioning members 36a and 36b are provided on the left and right sides of the small window 35. These positioning members 36a and 36b may be omitted. In this case, a locking plate with a shape such that both ends of the locking plate are attached to the main body of the door may be used. In the above embodiment, a small window 35 is provided at the center of the lower end of the door 30. The position of the small window 35 is not limited to this. However, if the small window is provided at a part of the end, the small window becomes recessed when the door is opened, making it easy to place long items such as cables in the small window.
[0041] In the above embodiment, the storage box 20 includes a door 30 provided in a portion of the wall 10 corresponding to an opening on one side of the space 11. The storage box may be placed in a space with openings on two opposing sides. In this case, at least one of the two openings is provided with a door with the above configuration.
[0042] In the above embodiment, the housing box 20 houses a power outlet as the connection source. The components housed in the housing box 20 as the connection source are not limited to a power outlet. For example, a water tap to which a water hose is connected may also be used.
[0043] Next, the technical concepts that can be understood from the above embodiments and alternative examples are described below. (a) The door is provided with a mounting member having a width corresponding to the closing member above the closing member, The closing member and the mounting member are connected by a hinge. The storage box according to claim 1 or 2, characterized in that the closing member rotates while being supported by the mounting member via the hinge to open the small window.
