[Figure 9] 1 is an exploded perspective view of a storage container used in a radio wave leakage prevention box according to an embodiment of the present invention; DETAILED DESCRIPTION OF THE INVENTION

[0018] Next, the radio wave leakage prevention box of the present invention will be described in detail with reference to Figures 1 to 9. In this specification, left, right, and top and bottom refer to directions when viewed from the front facing the first opening and closing door 14. The radio wave leakage prevention box 10 is an iron box manufactured by bending, welding, and, if necessary, cutting an approximately 1 mm thick plate (iron plate). The radio wave leakage prevention box 10 has a front-opening storage box 10A divided into two sections, upper and lower, by a partition wall 11: a first storage section 12 at a front opening 121 and a second storage section 13 at a front opening 131; a first opening / closing door 14 for opening and closing the front opening 121 of the first storage section 12; a second opening / closing door 15 for opening and closing the front opening 131 of the second storage section 13; a first key 16 attached to the first opening / closing door 14 for locking / unlocking the first opening / closing door 14; a second key 17 attached to the partition wall 11 for locking / unlocking the second opening / closing door 15; and a storage container 20 stored in the second storage section 13, which can hold multiple smart keys. The storage box 10A, partition wall 11, first opening / closing door 14, second opening / closing door 15 and storage container 20 are made of iron, a radio wave blocking material.

[0019] In the radio wave leakage prevention box 10, the first storage section 12 is surrounded by side walls 113a, 113b, a rear wall 112a, an upper wall 111, and a partition wall 11, which is a lower wall. When the first opening / closing door 14 is closed, a substantially sealed space is formed. The front ends of the side walls 113a, 113b are bent 90 degrees to form front wall edges 113c, 113d, and are further bent rearward 90 degrees to form guide pieces 113e, 113f of the first opening / closing door 14. The upper wall 111 is the inner wall of a double upper wall formed by bending the front of the outer upper wall. A plurality of hooks 121 for hanging the smart key 100 are attached to the upper part of the rear wall 112a, allowing the smart key 100 to be stored in a hanging position. Furthermore, support holes 142a, 142b that support the first opening / closing door 14 so that it can be opened and closed are formed respectively in the front of the upper wall 111 and the partition wall 11. Furthermore, a locking receptacle 16a that locks with a locking piece 161 of the first key 16 is formed in the side wall 113a. Furthermore, a second key 17 is formed in approximately the center of the partition wall 11. The keyhole of the second key 17 is formed on the first storage section 12 side, and cannot be operated when the first opening / closing door 14 is closed. Therefore, the second key 17 can only be locked and unlocked after the first opening / closing door 14 has been unlocked, which provides high safety.

[0020] The first opening / closing door 14 is rotatable by support shafts 141a and 141b that pass through support holes 142a and 142b. The first opening / closing door 14 is formed inside (at the back) of edges 113c and 113d that are part of the front wall. The first opening / closing door 14 is locked by operating the first key 16, when a locking piece 161 engages with a locking receiver 16a formed on the side wall 113a, and is unlocked by releasing the lock. The first opening / closing door 14 is a double door comprising a main opening / closing door 14A having a U-shaped vertical cross section, which has a plate-shaped first door body having a keyhole 165 and a first side panel extending inward from the upper and lower ends of the first door body, and a secondary opening / closing door 14B having a U-shaped vertical cross section, which has a plate-shaped second door body and a second side panel extending inward from the upper and lower ends of the second door body, and which is slidably inscribed within the main opening / closing door, and the first side panel of the main opening / closing door 14A has a long hole formed in it, through which support shafts 141a, 141b pass, and whose hole length in the left-right direction is larger than the shaft diameter of support shafts 141a, 141b, and the secondary opening / closing door 14B is fixed to the support shafts so as to be able to move in conjunction with the movement of support shafts 141a, 141b. The first door 14 opens sequentially from a first position where the front opening is closed by being locked, to a second position (shown by the dashed line in FIG. 6 ) where the main door is unlocked and slid linearly from the first position in the direction opposite to the locking mechanism to close the front opening, and to a third position where the first door 14 is rotated from the second position to open the front opening. The end 144 on the locking mechanism side (left side) of the first door 14 is crank-shaped in plan view. In the closed state where the locking piece 161 of the first door 14 is locked with the locking piece 16a, the end 144 conceals the gap between the edge 113c, which is part of the front wall, and the first door 14, preventing it from being broken by prying open with a crowbar. The first key 16 has a keyhole on the surface of the first door 14 and a locking piece 161 on the first storage section 12 side that rotates in conjunction with the rotation of the keyhole. This makes it possible to lock and unlock the first opening and closing door 14 using the mechanical key.

[0021] The crank-shaped end 144 on the locking receiving side of the first opening / closing door 14 has a first side that bends from the left end of the opening / closing door body and extends toward the anti-locking side, a second side that bends another 90 degrees and extends forward, a third side that bends another 90 degrees and extends beyond the left end of the opening / closing door body toward the locking side, a fourth side that bends further and extends forward, and a fifth side that bends further and extends toward the anti-locking side, and in a plan view, it has a shape that is a series of U-shapes and inverted U-shapes.

[0022] In the radio wave leakage prevention box 10, the second storage section 13 is surrounded by side walls 115a, 115b, a rear wall 112b, the partition wall 11 serving as the upper wall, and a bottom wall 114. When the second door 15 is closed, the second storage section 13 becomes a substantially sealed space. The front ends of the side walls 115a, 115b are bent 90 degrees to form part of the front wall and also serve as support sections 153a, 153b for the second door 15. Support holes 154a, 154b are formed in the support sections 153a, 153b, respectively, through which the support shaft of the second door 15 passes. A locking piece 171 of the second key 17, formed approximately in the center of the partition wall 11, is visible on the second storage section 13 side of the second key 17. The second storage section 13 also houses a storage container 20 capable of holding multiple smart keys.

[0023] The second door 15 has a plate-shaped door body and second side plates 15a, 15b that bend inward from both ends of the door body, and shaft holes through which support shafts pass are formed in the second side plates 15a, 15b. A protrusion 151 that facilitates the opening and closing of the first door 15 is formed on the front surface of the plate-shaped door body of the second door 15, and a locking receptacle 17a that locks a locking piece 171 of the second key 17 is formed on the back surface of the door body. The second key 17 has a keyhole on the first storage compartment 12 side of the partition wall 11 and a locking piece 171 on the second storage compartment 13 side that rotates in conjunction with the rotation of the keyhole. This allows the second door 15 to be locked and unlocked using a mechanical key.

[0024] FIG. 9 shows the storage container 20 stored in the second storage section 13. The storage container 20 is a lidded box formed by bending a 1 mm thick steel plate and, if necessary, welding or cutting it. The box body 21 with an upper opening can hold smart keys 200 other than the smart key 100 stored in the first storage section 12. The lid 22 that tightly covers the box body 21 is an outer lid consisting of a lower-opening top plate, left and right side plates, and front and rear side plates. The front plate of the lid 22 has a notch 221 formed to avoid the protrusion 151. This notch also prevents the front and rear of the lid 22 from being confused.

[0025] Next, we will explain how to use the radio wave leakage prevention box 10 of the present invention. First, prepare the smart keys 100 and 200 to be stored. Place multiple smart keys 200 in the box body 21 and close the lid 22 to seal the box. With the first and second doors 14 and 15 open, place the storage container 20 containing the smart keys 200 in the second storage section 13. Then, close the second door 15, operate the second key 17, and lock the second door 15. In this state, the storage container 20 is highly airtight, preventing radio wave leakage from the smart keys 200 stored in the storage container 20. Furthermore, since the storage container 20 is stored in the nearly airtight second storage section 13, it forms a double container, reliably preventing radio wave leakage. The operating key of the second key 17 can remain inserted in the keyhole.

[0026] Meanwhile, multiple smart keys 100 are hung from hooks 121 of the first storage section 12. Then, the first door 14 is closed and the first key 16 is operated to lock the smart key 100. Because the smart key 100 is stored in the sealed first storage section 12, radio wave leakage from the smart key 100 is prevented. When the first door 14 is locked, its end 144 conceals the gap between the edge 113c, which is part of the front wall of the first storage section 12, and the first door 14, preventing it from being broken by prying with a crowbar. The first door 14 is opened by a combination of sliding and rotating, which makes the operation complicated and difficult to open. Therefore, even if there is a slight gap, it is difficult to target, making it effective in preventing theft. The smart key 100 is convenient because it can be easily retrieved during the day, when the smart key 100 is used frequently, such as when starting and stopping a car, or when temporarily storing it. When the first opening / closing door 14 is locked, the second opening / closing door 15 is in a locked state, and the operation key for operating the second opening / closing door 15 is located in the first storage section 12, so the second opening / closing door 15 cannot be opened.

[0027] Next, to remove the smart key 100, the first key 16 of the first door 14 is unlocked and the first door 14 is opened. Then, the smart key 100 hanging on the hook 121 can be removed. Furthermore, to remove the smart key 200, the second key 17 attached to the partition wall 11 is unlocked to unlock the second door 15, the second door 15 is opened, the storage container 20 is removed from the second storage section 13, and the smart key 200 inside is removed. Removing the smart key 200 requires the unlocking operation of two keys, which is effective in preventing theft. In particular, for dealers who exhibit many cars and take care of customers' cars, this allows them to safely store multiple smart keys.

[0028] The radio wave leakage prevention box 10 is preferably wall-mounted for easy removal. There are no particular limitations on the method for hanging the radio wave leakage prevention box 10 on a wall, and various known methods can be used. For example, there is a method in which a locking recess or locking protrusion is formed on the rear wall of the radio wave leakage prevention box 10, and a corresponding locking protrusion or locking recess is formed on the wall of a room in a building, and these are locked together; or a method in which a hook is formed on the rear wall of the radio wave leakage prevention box 10, and a hook hanger for hanging the hook is formed on the corresponding fixed wall.

[0029] The radio wave leakage prevention box 10 is not limited to the above-described embodiment, and various modifications are possible. In the radio wave leakage prevention box 10, the partition wall may divide the storage box into two halves, for example, left and right halves, in addition to dividing the storage box into two halves, top and bottom. In this case, the left wall or right wall of the radio wave leakage prevention box 10 in FIG. 1 becomes the upper wall or the lower wall. Furthermore, the shape of the end 144 on the locking side of the first opening / closing door 14 is not limited to the crank shape described above, and may be a normal non-crank shape. In this case, it is sufficient that the inner wall, which is bent twice from the end of the corresponding side wall, and the end face of the first opening / closing door are close to each other without any gaps.

[0030] In the radio wave leakage prevention box 10, the radio wave blocking material is not limited to iron, and may be aluminum, for example. Furthermore, in the radio wave leakage prevention box 10, a hook for hanging the smart key 100 on the first storage section 12 may not be necessary. In this case, the first storage section 12 may simply be used as a place to place the smart key 100, or as a place to store small items other than the smart key 100. In the radio wave leakage prevention box 10, the storage container 20 may be an inner lid instead of an outer lid 22. Furthermore, the container is not limited to a rectangular container, and may be a circular container.

[0031] The radio wave leakage prevention box (1) of this invention has a front-opening storage box divided into two sections by a partition wall: a first storage section and a second storage section; a first door for opening and closing the front opening of the first storage section; a second door for opening and closing the front opening of the second storage section; a first key attached to the first door for locking and unlocking the first door; a second key attached to the partition wall for locking and unlocking the second door; and a storage container for storing multiple smart keys in the second storage section. The storage box, the partition wall, the first door, the second door, and the storage container are all made of radio wave blocking materials, so the storage container is stored in the doubly locked second storage section, which is effective in preventing theft. In addition, the doubly radio wave blocking feature reliably prevents radio wave leakage from the smart key stored in the storage container. This is particularly useful for car dealers, as it allows them to safely store multiple smart keys.

[0032] Furthermore, in the radio wave leakage prevention box (2) of the present invention, in the above (1), the radio wave blocking material is iron or aluminum, so there is more room for choice in manufacturing.

[0033] In addition, the radio wave leakage prevention box (3) of the present invention is configured as described above in (1), with multiple hooks formed on the wall of the first storage section, and multiple other smart keys can be hung from the hooks to store them. This prevents theft and blocks radio waves for the multiple other smart keys, ensuring safety and preventing radio wave leakage. It also requires only one lock / unlock operation, making it easy to use.

[0034] In addition, the radio wave leakage prevention box (4) of the present invention is the same as (1) above, in that the storage container consists of a container body with an upper opening and an outer lid or inner lid that closes the upper opening without any gaps, making it easy to manufacture and reliably preventing radio wave leakage from the smart key.

[0035] In addition, in the radio wave leakage prevention box (5) of the present invention, the first storage section and the second storage section are divided into two sections, upper and lower, by a partition wall, and the first storage section is located at the top of the storage box and the second storage section is located at the bottom of the storage box, so two storage locations are clearly defined: one smart key that is easy to use, and the other smart key that reliably prevents radio wave leakage.

[0036] In addition, in the radio wave leakage prevention box (6) of the present invention, in the above (1), the first door has a support shaft that supports the first door so that it can rotate freely, and the support hole through which the support shaft passes is an elongated hole whose length in the left-right direction is longer than the diameter of the support shaft, and the first door is opened and closed in the following order: a first position in which the front opening is closed by locking the first key, a second position in which the front opening is closed by unlocking and sliding the first door linearly in the anti-locking direction from the first position, and a third position in which the front opening is opened by rotating the first door from the second position. Therefore, the opening and closing operation of the first door is complicated, and it is difficult to pry open with a crowbar or the like, which is effective in preventing theft.

[0037] In addition, the radio wave leakage prevention box (7) of the present invention is easy to use because it is attached to a wall in the manner described above (1).

[0038] In addition, the radio wave leakage prevention box (8) of the present invention is manufactured by bending, welding, and cutting a plate-shaped body as required in (1), so it is robust and can prevent radio wave leakage from the smart key. [Explanation of symbols]
