Description

  The present invention relates to a portable electronic device communication blocking locker and a door-attached inner box or door-integrated door-attached inner box attached to the portable electronic device communication blocking locker.

  Many mobile phones have a recording function and a photographing function, and they may be prohibited in facilities that handle highly confidential information. Also, it is encouraged to turn off the mobile phone in places where the ringtone of the mobile phone is a nuisance to the surroundings, but it is difficult to thoroughly enforce it in places where many people gather. Yes.

  Therefore, conventionally, three layers of aluminum foil film are used, and a laminated product with a plastic film is formed into a bag shape, thereby blocking communication of a mobile phone housed therein, as seen in Patent Document 1. Packaging bags have been proposed. Distributing these packaging bags to users and thorough storage of mobile phones can prevent annoying ringtones in the facility. However, whether or not to put the mobile phone in the packaging bag is left to the user's intention, and it is actually difficult to completely prevent the ringtone.

  For this reason, facilities and the like that restrict the carrying of mobile phones keep the user's mobile phone when entering the facility. Usually, a cellular phone deposited from a user is stored in a locker or the like. As such a mobile phone storage locker, a plurality of storage spaces for storing a mobile phone are provided, and a door with a lock that opens and closes the opening of the storage space is provided in each of the storage spaces. Yes.

Registered Utility Model No. 3146497

  If the mobile phone of the user of the facility is stored in such a locker, it is possible to restrict the carrying of the mobile phone to the facility. However, if a mobile phone is turned on with such a locker turned on, a ringtone for a call or mail may sound during storage, and such a ringtone may be annoying depending on the location.

  Therefore, it is conceivable that the mobile phone storage locker has a radio wave blocking structure to block communication of the mobile phone being stored. However, since radio waves can enter even from a small gap, the entire locker must be formed of a conductive metal and have a highly sealed structure, which is very difficult to achieve.

  In recent years, many mobile electronic devices having communication functions other than mobile phones have been put into practical use, and it may be necessary to store such mobile electronic devices in a state where communication with the outside is interrupted. . When manufacturing a locker for storing such a mobile electronic device other than the mobile phone in a state where communication is cut off, the same problem as in the case of the mobile phone storage locker as described above occurs.

  The present invention has been made in view of these circumstances, and is attached to a portable electronic device communication blocking locker that can easily block communication with the outside of the stored portable electronic device and to such portable electronic device communication blocking locker. Another object is to provide an inner box with a door and an inner box with a door.

To solve the above problems, a portable electronic device communication blocking rocker of the present invention uses the existing rocker for opening and closing the opening of the housing portion of the lockers housing in which one side is open with the door body, the mobile internal locker a portable electronic device outage rocker that blocks communication of an electronic device, attached to the storage portion, and an inner box in which one side surface of the opening side of the housing part has a formed in a box shape which opens conductive , A door stop integrally formed around the opening of the inner box, and attached to either the door or the door stop of the locker, and when the door is closed, between the door and the door stop A shield member made of a conductive material having elasticity that seals the gap between the locker and a conductive plate affixed to the back surface of the door body of the locker. It is characterized by being able to block

  In such a configuration, the inner box forming the accommodation space for accommodating the portable electronic device is formed separately from the locker casing. In such a case, only the inner box and the door body and the clearance between them are the members that must have the radio wave blocking structure. For this reason, it is possible to easily cut off the communication of the portable electronic device to be stored as compared with the case where the entire locker has a radio wave blocking structure.

  The inner box of the portable electronic device communication blocking locker is formed of a conductive metal, conductive resin, conductive fiber or other conductive material, or the surface of the inner box casing made of a non-conductive material. Alternatively, it can be formed by attaching a conductive material inside.

  By the way, the addition of the communication blocking function of the mobile electronic device communication blocking locker in such a case adds the inner box formed as described above to the case of the existing locker, It can be realized simply by exchanging it with one having the. In other words, the portable electronic device communication blocking locker of the present invention can be realized by simply remodeling the case of an existing locker that does not have a radio wave blocking function and changing the door and adding an inner box. Is possible.

  In order to reliably cut off radio waves, it is necessary to securely seal the gap between the door body and the door stop with a shield member. In that respect, the door body is locked in a closed state, and if the lock body is provided to move the door body in a direction close to the door stop according to the locking operation, the door body is locked, The shield member is sandwiched between the door body and the door stop with a certain amount of pressure. Therefore, the sealing by the shield member can be surely performed, and communication with the outside of the portable electronic device to be stored can be more surely cut off.

  Incidentally, such a lock member includes an engagement hole and a stopper provided in the door body to lock the door body in a closed state in accordance with the engagement with the engagement hole. It is possible to realize the joint hole by forming the stopper plate in a shape that guides the stopper plate in the direction close to the door stop portion according to the engagement with the engagement hole. In this case, according to the locking operation of the locking member, that is, according to the engagement of the stopper with the engagement hole, the stopper is guided in the engagement hole and moves in the direction close to the door stop. Along with the movement of the clasp, the door body provided with the clasp moves in a direction close to the door stop, and a clamping pressure is applied to the shield member sandwiched between the door and the door stop. It will be.

  In addition, even if the clamping pressure of the shield member by such a door body and a door stop part is too large or too small, it will become difficult to perform radio wave interruption sufficiently. In that respect, the door body and the door contact portion, where the shield member is not attached and the position where the shield member fully contacts the door body toward the door contact portion by 0.3 to 0.7 mm. If the lock member is configured to be moved, the shield member can be clamped with an appropriate pressure, and radio waves can be sufficiently blocked.

  On the other hand, if the clamping pressure of the shield member varies from part to part, there is a concern that a gap is generated between the door body and the door stop part, and the radio wave blocking performance is lowered. In that respect, when the door body is closed until the opening angle becomes 3 to 6 °, the shield member should be disposed so as to come into contact with the door body and the door contact portion where the shield member is not attached. In this case, it becomes possible to reliably perform radio wave blocking by making the holding pressure of the shield member uniform.

Further, in order to solve the above problems, a door integrated doorstop with the box of the present invention is mounted in the holding section of the existing rocker for opening and closing the opening of the housing portion of the rocker housing that one side is open with the door body An inner box with a door stop , which is formed in a box shape with one side open, and has a conductive inner box , a door stop portion integrally formed around the opening of the inner box, and an inner box or door stop portion. A door body that opens and closes the opening of the inner box, and is attached to either the door body or the door stop portion, and when the door body is closed, the door body and the door stop portion It is characterized by comprising a shield member made of a conductive material having elasticity that seals the gap between them, and a conductive plate affixed to the back surface of the door body .

  If such an inner box with a door is attached to a locker casing to form a portable electronic device communication blocking locker, the inner box forming the accommodation space for accommodating the portable electronic device is formed separately from the locker casing. It will be. In such a case, only the inner box and the door body and the clearance between them are the members that must have the radio wave blocking structure. For this reason, it is possible to easily cut off the communication of the portable electronic device to be stored as compared with the case where the entire locker has a radio wave blocking structure. In addition, by installing such an inner box with a door to an existing locker housing that does not have a radio wave blocking function, and changing the locker door body to one that has a radio wave blocking function, the locker can be blocked from radio waves. It is possible to plan. Therefore, if such an inner box with a door is employed, a portable electronic device communication blocking locker having a radio wave blocking function can be realized by simply modifying the existing locker.

  Such an inner box with door contact is formed of a conductive metal, formed of a conductive resin or conductive fiber, or a conductive material on the surface or inside of an inner box housing made of a non-conductive material. Or can be formed.

  According to the portable electronic device communication blocking locker, the inner box with door and the inner box with door integrated door according to the present invention, it is possible to block communication with the outside of the stored portable electronic device without using a radio wave blocking structure for the entire locker. It can be done easily.

  Hereinafter, an embodiment in which the portable electronic device communication blocking locker and the inner box with door stop according to the present invention are embodied will be described with reference to FIGS. In this embodiment, it is assumed that the mobile electronic device stored in the locker is a mobile phone. However, the mobile electronic device communication blocking locker of this embodiment can be adjusted by appropriately adjusting the shape and dimensions of the accommodation space. In addition to these mobile phones, PHS, transceivers, radio controlled toys, wireless headphones, wireless earphones, wireless microphones, IC tags with built-in batteries, personal computers, personal digital assistants, wireless PC peripherals, electronic game machines, with wireless communication functions It can be embodied as a storage for other portable electronic devices that emit radio waves when operating, such as a pedometer, a heart rate meter with a wireless communication function, a wristwatch with a wireless communication function, a wireless key, and the like.

  In FIG. 1, the external appearance of the portable electronic device communication interruption | blocking locker of this embodiment is shown. As shown in the figure, this portable electronic device communication blocking locker includes a locker housing 1 formed in a rectangular parallelepiped shape with one side (front in the figure) open, and a door 2 attached to the locker housing 1. And. In the present embodiment, the locker casing 1 is made of metal (for example, steel). However, the locker casing 1 is formed of resin or wood when it is necessary to reduce the weight or when the design of the appearance is required. It is also possible to do.

  The door body 2 is pivotally supported around a pivot shaft provided at an edge of the opening of the locker casing 1 so as to be pivotable, and opens and closes the opening of the locker casing 1 according to the pivot. Is attached. Incidentally, in the portable electronic device communication blocking locker of the present embodiment, a lock member 8 (locking device) for locking the door 2 in the closed state is provided, and an operation key (not shown) is inserted into the keyhole 9 to perform the locking operation. By doing so, the door body 2 is held in a closed state.

  FIG. 2 shows a perspective cross-sectional structure of the portable electronic device communication blocking locker of the present embodiment. As shown in the figure, the locker housing 1 has a rectangular parallelepiped housing portion 3 having an opening on one side surface (front surface in the figure), and inside the housing portion 3 is an inner box 4 with a door. Is fixed.

  FIG. 3 shows the appearance of the inner box 4 with such a door stop. As shown in the figure, the inner box 4 with a door stop is formed in a rectangular parallelepiped shape with one side opened. Such an inner box 4 with a door stop is formed by integrating five conductive metal plates such as stainless steel. And the joint of each board | plate material is welded so that it may have very high sealing performance. In addition, the door stop part 5 is integrally formed around the opening of the inner box 4 with the door stop, and when the door body 2 is closed, the door body 2 (more precisely, the door body 2 Shield members 6a to 6d), which will be described later, attached to the back surface come into contact with the door stop portion 5.

  FIG. 4 shows the appearance of the door 2 as seen from the back side. As shown in the figure, a conductive metal plate 7 having conductivity such as stainless steel is attached to the back surface of the door body 2 so as to cover the entire surface, and shield members 6a to 6d are provided on the four sides thereof. Is attached. The shield members 6a to 6d are made of a conductive material having elasticity, and seal the gap between the door body 2 and the door stop portion 5 when the door body 2 is closed. In this embodiment, as the shield members 6a to 6d, those having a structure in which a conductive fabric made of nickel-plated nylon material is covered with a core material of urethane sponge are used. Moreover, in this embodiment, what has a V-shaped cross section as a shield member 6a is employ | adopted as one side (side on the right side in the figure) near the rotation axis of the door body 2, and the remaining three sides are As the shield members 6b to 6d, those having a semicircular cross section are adopted.

  FIG. 5 shows a planar cross-sectional structure of the portable electronic device communication blocking locker when the opening angle of the door body 2 is 4.5 °. As shown in the figure, in the portable electronic device communication blocking locker of the present embodiment, when the door body 2 is closed until the opening angle becomes 4.5 °, the first contact with the door stop 5 is made. Shield members 6a to 6d are attached. More specifically, the shield member 6a attached to a portion near the rotation axis of the door body 2 comes into contact with the door stop portion 5 at this time. If the holding pressure of the shield members 6a to 6b sandwiched between the conductive plate 7 on the back surface of the door body 2 and the door contact portion 5 when the door body 2 is closed varies depending on the part, the door body 2 and the door contact portion There is a concern that a gap may be generated between the two and the radio wave blocking performance may be reduced. In that respect, if the shield members 6a to 6d are arranged so as to come into contact with the door stop portion 5 when the door body 2 is closed until the opening angle becomes 4.5 °, the shield members 6a to 6b are sandwiched. Experiments have confirmed that it is possible to block radio waves reliably with a uniform pressure.

  FIG. 6 shows the structure of the lock member 8 employed in the portable electronic device communication blocking locker of this embodiment. FIG. 6 shows the structure around the lock member 8 through the door body 2. As shown in the figure, the lock member 8 is provided on the door body 2, and includes a stopper 10 that is rotated by inserting an operation key (not shown) into the keyhole 9 and performing a locking operation, and a locker housing. And an engagement hole 11 formed at the edge of the opening of the body 1. In the portable electronic device communication blocking locker of the present embodiment, the engagement hole 11 is formed in a shape that guides the stopper plate 10 in the direction close to the door stop 5 in accordance with the engagement with the engagement hole 11. Has been.

  In FIG. 7, the state before the door 2 is locked by the lock member 8 of the portable electronic device communication blocking locker of the present embodiment is indicated by a one-dot chain line, and the state after the lock is indicated by a solid line. In the figure, the displacement of the door body 2 before and after the lock is exaggerated. In this embodiment, by forming the engagement hole 11 in the shape as described above, the lock member 8 locks the door body 2 in the closed state, and the door body 2 is brought into contact with the door according to the locking operation. It is comprised so that it may move to the direction close | similar to the part 5. FIG. More specifically, the lock member 8 moves the door body 2 toward the door stop portion 5 by 0.5 mm from the position where the door stop portion 5 and the shield member come into full contact in accordance with the locking operation. It is configured. Even if the clamping pressure of the shield members 6a to 6d by the door body 2 and the door contact portion 5 is too large or too small, it is difficult to sufficiently block radio waves. If the lock member 8 is configured to move 2 by 0.5 mm, it has been experimentally confirmed that the shield members 6a to 6d can be sandwiched with an appropriate pressure to sufficiently block radio waves.

  As described above, in the portable electronic device communication blocking locker of the present embodiment, the conductive plate 7 attached to the back surface of the door body 2 and the inner box 4 with door contact fixed to the housing portion 3 of the locker housing 1 are electrically conductive. It is made of a metal having properties. Further, when the door body 2 is closed and locked, the gap between the back surface (conductive plate 7) of the door body 2 and the door stop portion 5 of the inner box 4 with door stop is made by the shield members 6a to 6d having conductivity. It becomes completely sealed. Therefore, when the door body 2 is closed and locked, the inside of the inner box 4 with the door stop is in a state of being shielded from external radio waves. Therefore, if the portable electronic device is stored in such a portable electronic device communication blocking locker, communication with the outside is blocked, so that a notification sound such as a ringtone sounds even if the portable electronic device is still on. Can be prevented.

According to the portable electronic device communication cut-off locker and the inner box with a door as described above, the following effects can be obtained.
(1) The portable electronic device communication blocking locker of the present embodiment includes a locker casing 1 having an accommodating portion 3 opened on one side, and a door body 2 attached to the locker casing 1 to open and close the opening of the accommodating portion 3. And an inner box 4 with a door-to-door having conductivity and formed in a rectangular parallelepiped shape that is open on one surface and attached to the accommodating portion 3. In such a configuration, the inner box 4 with a door which forms a housing space for housing the portable electronic device is formed separately from the locker housing 1. In such a case, only the inner box 4 with the door stop and the door body 2 and the clearance between them are the members that should have the radio wave blocking structure. For this reason, it is possible to easily cut off the communication of the portable electronic device to be stored as compared with the case where the entire locker has a radio wave blocking structure.

  (2) Communication of portable electronic devices can be achieved simply by adding the inner box 4 with a door-end formed as described above to the case of an existing locker and replacing the door body 2 with one having radio wave blocking properties. A blocking function can be added to the portable electronic device communication blocking locker. Therefore, a portable mobile phone with a communication blocking function can be obtained by simply remodeling the case of an existing locker that does not have a communication blocking function and changing the door 2 and adding an inner box 4 with a door. An electronic device communication blocking locker can be realized.

  (3) In the present embodiment, the door stopper 5 integrally formed around the opening of the inner box 4 with the door stop, and the door body when the door body 2 is closed by being attached to the door body 2. 2 and shield members 6 a to 6 d made of a conductive material having elasticity that seals the gap between the door stop 5 and the door stop 5. For this reason, it is possible to reliably block the penetration of radio waves from the gap between the door body 2 and the door stop 5.

  (4) In the present embodiment, the door body 2 is locked in a closed state, and a lock member 8 is provided for moving the door body 2 in a direction approaching the door stop portion 5 in accordance with the locking operation. . More specifically, an engagement hole 11 provided in the locker housing 1 and a stopper 10 provided in the door body 2 to lock the door body 2 in a closed state in accordance with the engagement with the engagement hole 11. And the locking hole 8 is formed, and the engagement hole 11 is formed in a shape that guides the stopper plate 10 in the direction close to the door stop 5 according to the engagement with the engagement hole 11. I am doing so. Then, in accordance with the locking operation, the lock member 8 is configured so that the door body 2 is moved toward the door stop portion 5 by 0.5 mm from the position where the door stop portion 5 and the shield members 6a to 6d are in full contact. doing. Therefore, the shield members 6a to 6d come to be sandwiched between the door body 2 and the door stop portion 5 with an appropriate pressure, and the sealing by the shield member is ensured, and the communication with the outside of the stored portable electronic device is blocked. It becomes possible to carry out more reliably.

  (5) In the present embodiment, when the door body 2 is closed until the opening angle becomes 4.5 °, the shield members 6a to 6d are arranged so as to be in contact with the door stop portion 5 for the first time. Yes. For this reason, it is possible to make sure that the shielding pressure between the shield members 6a to 6d between the door body 2 and the door contact portion 6 when the door body 2 is closed is uniform, and to cut off radio waves reliably.

  (6) The inner box 4 with a door stop of the present embodiment is a portable electronic device communication blocking locker provided with a door 2 that opens and closes the opening of the housing 3, in which the housing 3 is opened on one side. It is an inner box attached to the accommodating part 3 of the locker housing 1, and is formed in a box shape having one surface opened by a conductive metal. And the door stop part 5 which is integrally formed around the opening of the said inner box and contacts the door body 2 when the door body 2 is closed is provided. If such an inner box 4 with a door is attached to the locker casing 1 to form a portable electronic device communication blocking locker, an inner box forming a storage space for storing the portable electronic device is formed separately from the locker casing 1. Will be. In such a case, only the inner box 4 with the door stop and the door body 2 and the clearance between them are the members that should have the radio wave blocking structure. For this reason, it is possible to easily cut off the communication of the portable electronic device to be stored as compared with the case where the entire locker has a radio wave blocking structure. Moreover, the inner box 4 with a door is attached to the case of an existing locker that does not have a radio wave blocking function, and the locker door 2 is changed to one having a radio wave blocking function. It is possible to cut off radio waves. Therefore, if such an inner box 4 with a door is employed, a portable electronic device communication blocking locker having a radio wave blocking function can be realized by simply modifying an existing locker.

The above embodiment may be modified as follows.
In the above embodiment, the inner box 4 with a door stop has a rectangular parallelepiped shape with one opening, but the shape can be arbitrarily changed. For example, the inner box 4 with a door stop may be formed in a cylindrical shape. Further, the shape of the locker housing 1 may be arbitrarily changed as appropriate.

  -You may make it attach a sound absorption material and a sound insulation material to the main location of the locker housing | casing 1 of the portable electronic device communication interruption | blocking locker of the said embodiment, or the inner box 4 with a door stop. For example, a sound absorbing material or a sound insulating material may be provided so as to cover the inner box 4 with door and the inner surface or outer surface of the door body 2. In this case, even when the radio wave interruption is incomplete due to some reason and a notification sound (for example, a ringing tone of a mobile phone) of a portable electronic device stored inside sounds, the sound leaking to the outside can be reduced. Moreover, it can replace with such a sound absorption material and a sound insulation material, or can attach a damping material to the main location of the locker housing | casing 1 or the inner box 4 with a door stop in addition to a sound absorption material or a sound insulation material. In this case, even if a portable electronic device having a so-called vibrator function, such as that found in a normal cellular phone, vibrates due to the operation of the same function, it propagates to the outside or is caused by the vibration. Generation of noise from the body 1 or the inner box 4 with a door stop can be suppressed. In addition, for example, when the portable electronic device communication blocking locker is installed in an environment such as an aircraft where there is large vibration or vibration, the inner wall of the inner box 4 and the portable electronic device frequently collide with each other to generate vibration and noise. May occur. However, as described above, the generation of such vibration and noise can be suppressed by attaching the sound absorbing material, the sound insulating material, and the vibration damping material to the main portions of the locker housing 1 and the inner box 4 with the door. Will be able to.

  -By attaching conductive resin, conductive fiber, radio wave absorber, conductive urethane sponge, conductive polymer, conductive sheet, conductive nano material, etc. to the main parts of the locker housing 1 and inner box 4 with door contact The radio wave blocking property may be further enhanced.

  In the portable electronic device communication blocking locker of the above embodiment, since the communication blocking of the portable electronic device stored by the inner box 4 with door and the door body 2 is achieved, the locker housing 1 has a special function. Without it, a portable electronic device communication blocking locker having a radio wave blocking function can be formed. Therefore, the locker housing 1 can be formed of an arbitrary material such as an aluminum alloy, a resin, or wood. As a result, it is possible to reduce the weight of the portable electronic device communication blocking locker and increase its convenience, and it is possible to improve the design of the locker by changing the material. Further, if a material such as a conductive resin, a radio wave absorber, a conductive polymer, or a conductive nano material is used as the material used for the locker casing 1, the radio wave blocking property of the portable electronic device communication blocking locker is further enhanced. It becomes possible.

  In the above embodiment, the shield members 6 a to 6 d are attached to the conductive plate 7 provided on the back surface of the door body 2, but these can be attached to the door stop 5. FIG. 8 shows the appearance of the inner box 4 with a door in such a case. As shown in the figure, shield members 6a to 6d are attached to the four sides of the door stopper 5 so as to surround the opening of the inner box 4 with the door stopper. Even in such a case, leakage of radio waves from the portion between the door body 2 and the door stop portion 5 can be similarly performed. In this case as well, when the door body 2 is closed until the opening angle becomes 4.5 °, the shield members 6a to 6d are attached so as to contact the conductive plate 7 on the back surface of the door body 2 for the first time. For example, the clamping pressure of the shield members 6a to 6d between the door body 2 and the door stop portion 5 can be made uniform. Also in this case, if the door 2 is locked in the closed state and the lock member 8 is provided to move the door 2 in the direction close to the door stop 5 in accordance with the locking operation, the door is provided. The shield members 6a to 6d are sandwiched between the body 2 and the door stop portion 5 with an appropriate pressure, so that the sealing by the shield member can be ensured.

  In the above embodiment, the inner box 4 with door contact and the conductive plate 7 on the back surface of the door body 2 are made of stainless steel. These members can be formed of a metal other than stainless steel such as a general steel material as long as it is a metal having conductivity. However, unlike stainless steel, when using a metal that may cause rust, it is necessary to coat the surface with a rust preventive paint. In such a case, if the shield members 6a to 6d are directly attached on the painted surface, there is a possibility that radio waves may enter through the paint layer. That is, when coating the member to which the shield members 6a to 6d are attached (the conductive plate 7 or the door stop portion 5), masking as shown in FIG. For the masking at this time, for example, a tape-like material in which a release paper 21 is stuck on the surface of a conductive metal foil material 20 such as an aluminum alloy can be used. Subsequently, as shown in FIG. 9B, the surface of the masked member is coated with a rust preventive paint 22. Thereafter, as shown in FIG. 9C, when the release paper 21 for masking is peeled off, the metal foil material 20 is exposed on the surface of the shield member mounting portion. And, if the shield member 23 is attached to the exposed surface of the foil material 20, a layer of non-conductive paint 22 is not interposed between the member (the conductive plate 7 or the door stop portion 5) and the shield member 23. The radio wave can be surely cut off.

  In the above embodiment, the inner box 4 with door contact is formed of a metal having conductivity such as stainless steel, but the material of the inner box 4 with door contact is conductive and has a function of blocking radio waves. Any possible material can be used. As a material used for the inner box 4 with a door stop, for example, a conductive resin, a conductive fiber, a radio wave absorber, a conductive polymer, a conductive nano material, or the like can be used.

  In the above embodiment, the inner box 4 with door contact is made of a conductive material, but a conductive metal, conductive resin, conductive material is formed on the surface of a nonconductive material such as a general resin. By attaching a conductive material made of conductive fiber, radio wave absorber, conductive polymer, conductive nano material, etc., conductivity may be added to the inner box 4 with door. Further, by forming the inner box 4 with a door by using a material in which the conductive material as described above is sandwiched between a pair of plates made of a non-conductive material such as resin or wood, the inner box with a door It is also possible to add conductivity to 4. In addition, by applying plating to the surface of the inner casing made of non-conductive material such as resin or wood, or applying conductive paint to the same surface, conductivity is added to the inner box with doors. You can also Furthermore, a multi-layer plate material in which a layer made of a conductive material is interposed between layers made of a non-conductive material, such as a plate material of a three-layer structure in which a pair of plate-shaped members are surface-bonded with a conductive adhesive. By using the inner box 4 with door to door, conductivity may be added to the inner box 4 with door to door. That is, the inner box 4 with a door stop may be formed by attaching a conductive material to the surface or inside of the inner box housing made of a non-conductive material.

  In the above embodiment, the shield members 6a to 6d have V-shaped cross sections and semicircular cross sections. However, other cross-sectional shapes may be employed. Moreover, in the said embodiment, although the thing of the structure which coat | covered the conductive fabric which consists of the nylon raw material which gave nickel plating to the core material of urethane sponge was used, the thing of other structures is used for the shield member 6a. It can also be used as ˜6d. That is, it has sufficient conductivity that can block radio waves of the portable electronic device, and has sufficient elasticity to seal the gap between the door body 2 and the door stop portion 5 when the door body 2 is closed.

Further, an engagement hole 11 or the like of the lock member 8 that locks the door 2 in the closed state is integrally provided in the inner box with a door-integrated door stop, or a magnet catch or elastic that holds the door 2 in the closed state. A member can also be provided integrally in an inner box with a door-integrated door stop. If the shield members 6a to 6d are attached to either the door stopper 5 of the inner box 4 with door stop or the conductive plate 7 of the door body 2, all the functions related to radio wave blocking are provided to the door integrated door box. You can have it. In such a case, the door body 2 is directly provided in the inner box 4 with the door stop, and compared with the case where the door body 2 is provided indirectly via the locker housing 1, the door body 2 and the door stop inner space are provided. The relationship with the box 4 can be closely strengthened. Therefore, it becomes possible to further improve the sealing property and the electric wave blocking property. In addition, the above-mentioned door-integrated inner box with doors can be assembled into an existing locker housing or rack of various shapes as a single finished product, thereby making it easy to make a portable electronic device communication blocking locker with a radio wave blocking function. It can also be manufactured at low cost. In this case, any material such as aluminum alloy, resin, or wood can be used for the locker housing 1 as long as it can fix and support the inner box with a door-integrated door. Therefore, it is possible to improve convenience, improve designability, and further reduce costs.

  In addition, as described above, in the configuration in which the door body 2 is attached to the inner box 4 with a door stop, a separate door body is further attached to the locker housing 1 so that the portable electronic device communication blocking locker is doubled. It is good also as a structure. In this case, it is possible to further improve the sealing performance and sound insulation performance of the portable electronic device communication blocking locker as a whole. In addition, when such a double door structure is adopted, the door attached to the locker casing 1 can be formed of any material in the same manner as the main body of the locker casing 1. If both are made of a conductive material, the portable electronic device communication blocking locker has a double wave blocking structure by the locker housing 1 and the inner box 4 and has an extremely high blocking function. .

  In the above embodiment, when the door body 2 is closed until the opening angle becomes 4.5 °, the shield body 6a to 6d of the door body 2 and the door contact portion 5 is not attached to the first one. The shield members 6a to 6d are attached so as to come into contact with each other. If the opening angle is set to 4.5 °, it is optimal for uniforming the clamping pressure of the shield members 6a to 6d, but a certain effect can be obtained even if the opening angle is slightly small or slightly large. Can do. Therefore, as long as sufficient radio wave blocking can be performed, the opening angle of the door body 2 when the shield members 6a to 6d are in contact for the first time may be appropriately changed. Incidentally, it has been confirmed that if the opening angle is set within a range of 3 ° to 6 °, sufficient radio wave blocking can be performed.

  -In the said embodiment, only the door contact is 0.5 mm from the position which the shield member 6a-6d of the door body 2 and the door stop part 5 and the shield member 6a-6d contact | abut in full contact The lock member 8 is configured to move the door body 2 toward the portion 5. The optimal amount of movement for blocking radio waves between the door body 2 and the door stop 5 is 0.5 mm. However, even if the amount of movement is somewhat small or large, a certain effect can be obtained. Therefore, as long as sufficient radio wave blocking can be performed, the amount of movement of the door body 2 toward the door stop portion 5 accompanying the locking operation of the lock member 8 may be appropriately changed. Incidentally, it has been confirmed that sufficient radio wave blocking can be performed if the amount of movement is set within a range of 0.3 to 0.7 mm.

  In the above embodiment, the engagement hole 11 provided in the locker housing 1 and the stop provided in the door body 2 to lock the door body 2 in a closed state in accordance with the engagement with the engagement hole 11. The gold 10 is provided. Then, by forming the engagement hole 11 in a shape that guides the stopper plate 10 in the direction of approaching the door stop portion 5 in accordance with the engagement with the engagement hole 11, the door is accompanied with the locking operation of the lock member 8. The body 2 was moved to the door stop 5 side. Even in other configurations, the configuration of the lock member may be changed as appropriate as long as the door 2 can be moved to the door stop 5 side in accordance with the locking operation.

  In the above embodiment, the door body 2 is provided with the lock member 8 that locks the door body 2 in the closed state and moves the door body 2 in the direction of approaching the door stop portion 5 according to the locking operation. The moderate clamping pressure of the shield members 6a to 6d between the door stop portions 5 is ensured. However, as long as an appropriate clamping pressure can be secured, the clamping pressure of the shield members 6a to 6d may be secured by means other than the lock member 8. For example, a configuration in which a magnet catch for attracting and holding the door body 2 is provided and the clamping pressure of the shield members 6a to 6d is secured by the electromagnetic attraction force of the magnet catch is conceivable.

  -In the said embodiment, although the seam of each board | plate material which comprises the inner box 4 with a door stop was welded, it was made to have very high sealing performance, but in addition to this, it is electroconductive between the seams. You may make it enclose conductive paste materials, such as an adhesive agent. According to such a structure, it becomes possible to further improve the radio wave shielding property of the inner box 4 with a door stop. In particular, when adopting a welding method such as spot welding in which the seam is partially welded instead of the entire seam, a minute gap may occur at the seam. However, by blocking the conductive paste material as described above in the gap, it is possible to ensure the radio wave blocking property.

  In addition, the inner box 4 is formed into a box shape by welding a plurality of plate materials as described above, for example, a single plate material made of a material having extensibility such as metal is formed into a box shape by deep drawing. Or can be formed in a box shape by injection molding of resin. In the inner box 4 formed through such a construction method, there is no gap at all other than the contact portion between the door stop portion 5 and the door body 2, so that the radio wave shielding property and sound insulation property can be further enhanced. become. Moreover, if the inner box 4 is manufactured by a method such as deep drawing or injection molding, the time required for manufacturing the inner box 4 is greater than when the inner box 4 is formed by welding a plurality of plate materials. Can be significantly shortened, and the production efficiency of the inner box 4 and thus the portable electronic device communication blocking locker can be greatly improved.

  In the above embodiment, the shield members 6a to 6d made of a conductive material having elasticity that seals the gap between the door body 2 and the door stop portion 5 when the door body 2 is closed are used as the door body 2 and the door. Although it is attached to any one of the contact portions 5, any material that does not have elasticity, for example, a conductive material, can be used as long as it can reliably prevent radio waves from entering through the gap between the door body 2 and the door contact portion 5. A conductive resin, a radio wave absorber, a conductive polymer, a conductive nanomaterial, or the like can be used as the material of the shield members 6a to 6d.

  Further, if the radio waves can be reliably prevented from entering through the gap between the door body 2 and the door stop portion 5 without providing the shield members 6a to 6d, the shield members 6a to 6d may be omitted. good.
