Description

[Technical field]

[0001] The present invention relates to a security door structure and to a wall-like structure comprising a security door structure. [Background technology]

[0002] Conventionally, for the purpose of crime prevention or storing valuables, a secret room (sometimes called a "hidden room" or a "security room") may be provided adjacent to a specific room in a building as a concealed space hidden from the specific room. In this case, the specific room and the secret room are divided into two by a partition wall, for example. In addition, a secret door (sometimes called a "hidden door" or a "security door") is provided in the partition wall so as to be freely opened and closed, for entering and leaving the secret room from the specific room, and only specific people who know the existence of the secret room (for example, the manager of the secret room, etc.) can enter the secret room through the secret door and manage the valuables and the like inside the secret room.

[0003] Here, as inventions relating to such secret rooms and secret doors, a partition structure using sliding doors as described in Patent Document 1 and a building as described in Patent Document 2 have been proposed.

[0004] The partition structure in Patent Document 1 involves providing a closet adjacent to an opening such as a doorway formed in the wall of a Japanese-style room, and the door that opens and closes the opening and the storage opening of the closet is constructed as a sliding door that can move between the opening and the storage opening. By using this sliding door as a shared door that can be opened and closed freely between both the storage opening of the closet and the opening of the Japanese-style room, the wall adjacent to the closet is effectively used as an entrance and exit to a storeroom (see abstract of Patent Document 1).

[0005] According to Patent Document 1, this sliding door can be seen from inside the Japanese-style room as a door for opening and closing a closet, so a storeroom can be placed adjacent to the Japanese-style room without ruining the atmosphere of the room, and this storeroom becomes something like a hidden room (see paragraph

[0016] of Patent Document 1).

[0006] The building in Patent Document 2 comprises a staircase connecting the lower floor (in this embodiment of the invention, the first floor) and the upper floor (in this embodiment of the invention, the second floor), a first room (in this embodiment of the invention, a bedroom) and a second room (in this embodiment of the invention, a theater room) located on either side of the staircase on the upper floor (second floor), a passageway leading to the bottom of the staircase and the first room (bedroom) and the second room (theater room), and a study located on the opposite side of the bottom of the staircase and connecting the first room (bedroom) and the second room (theater room) (see the abstract of Patent Document 2, and paragraphs

[0020] ,

[0021] , and

[0024] ). In the building of Patent Document 2, the doorway connecting the study and the bedroom is formed in a first partition wall that separates the bedroom and the staircase, and the doorway connecting the study and the theater room is formed in a second partition wall that separates the theater room and the staircase, and the doorway of the study is provided with a fitting (see paragraph

[0024] of Patent Document 2). In the building of Patent Document 2, the fitting on the bedroom side has a first bookshelf that faces the bedroom when the doorway is closed, and a second bookshelf is built into the surface of the first partition wall facing the bedroom, and the first and second bookshelves are unified in shape and color so that they collectively form a single bookshelf when the fittings are closed (see paragraph

[0025] of Patent Document 2).

[0007] According to Patent Document 2, fittings are installed at the entrances between the study and the bedroom and theater room, so that when the fittings are closed, the occupant using the bedroom or theater room cannot see the study. However, when the fittings are opened, the study can be seen in a place where one would normally expect a passageway, making the space seem even more interesting (see paragraph

[0030] of Patent Document 2). According to Patent Document 2, the fitting on the bedroom side has a first bookshelf that faces the bedroom when the entrance is closed, and a second bookshelf is built into the bedroom side of the first partition wall where the entrance opens, and when the fitting on the bedroom side is closed, the first and second bookshelves are lined up in the front-to-back direction, so that the first and second bookshelves together form a single bookshelf and the presence of the fitting cannot be felt, giving the study the feeling of a hidden room. As a result, a person using the bedroom is unaware of the presence of the study, and when using the study, they can feel the excitement of entering a hidden room (see paragraph

[0031] of Patent Document 2). [Prior art documents] [Patent documents]

[0008] [Patent Document 1] Japanese Patent Application Publication No. 8-105222 [Patent Document 2] JP 2023-10282 A Summary of the Invention [Problem to be solved by the invention]

[0009] The partition structure described in the above Patent Document 1 is configured to provide a hidden room by making a sliding door installed at an opening in the wall of a Japanese-style room appear as a door for opening and closing a closet (not as a storeroom as a hidden room) from inside the Japanese-style room, thereby hiding the existence of the hidden room (that is, in this case, a storeroom) from people inside the Japanese-style room. That is, in this case, the sliding door is configured to function as a so-called secret door (that is, a hidden door or security door). And only those who know that the sliding door is a secret door (for example, a family member who is in charge of the storeroom) can enter and leave the storeroom as a hidden room through the sliding door.

[0010] In addition, in the building described in Patent Document 2, in order to provide a hidden room, a first bookshelf is provided on the fittings on the bedroom side located on one side of the study (which will be the hidden room) that faces the bedroom (i.e., is exposed on the bedroom side) when the doorway is closed by the fittings, and a second bookshelf is built into the first partition wall that separates the bedroom and the staircase that faces the bedroom (i.e., is exposed on the bedroom side). Furthermore, when the doorway is closed by the fittings (on the bedroom side), the first and second bookshelves are unified in shape and color so as to form a single bookshelf as a whole, thereby hiding the existence of the hidden room (i.e., the study in this case) from people in the bedroom. That is, in this case, the fittings on the bedroom side are configured to function as a so-called secret door (i.e., a hidden door or security door). And, only those who know that the fittings on the bedroom side are secret doors (for example, a family member who is the manager of the building) can enter and leave the study as a hidden room through the fittings on the bedroom side.

[0011] [Inventors' unique findings] The present inventors have conducted extensive research and development into the above-mentioned secret room (i.e., security door) that is provided for crime prevention purposes, valuables storage purposes, and the like. As a result, according to the knowledge of the present inventors, even if a storeroom as a hidden room is concealed by a sliding door as a hidden door, as in the partition structure of Patent Document 1, the hidden door is composed of a sliding door formed in an opening in a wall, and is still a door (i.e., the partition structure of Patent Document 1 does not hide or camouflage the hidden door itself). Therefore, if a person who does not know that the sliding door is a hidden door (i.e., a person other than the manager) accidentally or mistakenly opens the sliding door to open the opening on the storeroom side (i.e., the opening of the Japanese-style room) instead of opening the storage opening of the closet, the existence of the storeroom as a hidden room will be known through the opening on the storeroom side, and the sliding door will be known to be a hidden door. As a result, from then on, anyone (other than the manager) can freely enter and exit the storeroom, which serves as a hidden room, through the sliding door.

[0012] Furthermore, as in the building of Patent Document 2, if a study serving as a hidden room is provided with a bookshelf (i.e., the first bookshelf) in a fitting on the bedroom side that serves as a hidden door (i.e., in the case of Patent Document 2, it is a hinged door that opens onto the bedroom side, but which opens inwards when viewed from the study serving as a hidden room), the fact that the fitting is a hinged door can be hidden (i.e., camouflaged) from anyone other than the manager entering the bedroom. However, even in this case, if a person (i.e., a person other than the manager) who does not know that the fitting (i.e., the fitting camouflaged by the first bookshelf) is a hidden door accidentally or mistakenly pulls the first bookshelf that camouflages the fitting toward himself, the fitting (i.e., the fitting as a hinged door camouflaged by the first bookshelf) will open, and the existence of the study as a hidden room will become known through the opening in the first partition wall in which the fitting is installed, and the fitting (i.e., the fitting as a hinged door camouflaged by the first bookshelf) will become known to be a hidden door. As a result, from then on, that person (other than the manager) can freely enter and exit the study as a hidden room through the fitting (i.e., the fitting as a hinged door camouflaged by the first bookshelf).

[0013] On the other hand, according to the findings of the present inventors, even in the case of a hidden room configured as disclosed in the above Patent Document 1 or Patent Document 2 (the storeroom in the case of Patent Document 1, and the study in the case of Patent Document 2), the above-mentioned problem (i.e. the problem of the hidden door being accidentally opened by a person other than the administrator) can be addressed by providing a door lock (sometimes called a "door lock") consisting of a key and a lock on the hidden door of the hidden room (the sliding door in the case of Patent Document 1, and the fixture in the case of Patent Document 2). That is, if only the manager of the hidden room and the hidden door knows the existence of the lock and the position of the lock (i.e., the installation position of the lock relative to the hidden door), and only the manager knows how to unlock the lock (i.e., the manager holds and manages a key with a lock structure that can unlock the lock), and the lock is locked except when entering the hidden room, even if a person other than the manager opens the sliding door or hinged door without knowing that it is a hidden door (i.e., accidentally or by mistake), the sliding door or hinged door cannot be opened. In this way, the sliding door or hinged door will not open, and the sliding door or hinged door will not be known to anyone other than the manager, so the existence of the hidden room can be concealed or hidden from anyone other than the manager.

[0014] On the other hand, even if a lock is provided on the hidden door as described above, if a person other than the administrator becomes aware that the sliding door or hinged door is a hidden door, the person other than the administrator may attempt to open the sliding door or hinged door. However, even if a person other than the administrator accidentally, unintentionally, or by mistake attempts to open the sliding door or hinged door, the lock can prevent the sliding door or hinged door from opening. In this case, the person other than the administrator can assume that a lock is installed on the hidden door, and may attempt to unlock the lock. However, even in this case, if a person other than the administrator does not know the position of the lock (i.e., the position where the lock is attached to the hidden door) or does not know how to unlock the lock (even if they know the position of the lock) (i.e., they do not possess or manage a key with a key structure that can unlock the lock), they will not be able to unlock the lock, and as a result, they will not be able to unlock and open the hidden door and enter or exit the hidden room.

[0015] However, even when a lock is provided on the hidden door as described above, it is desirable from the viewpoint of the security of the hidden room (or hidden door) to conceal the existence of the hidden door leading to the hidden room to the maximum extent, assuming the worst case scenario, and to be able to prevent the opening of the hidden door to the maximum extent even if the existence of the hidden door is known to a person other than the administrator. Furthermore, in relation to the wall or partition in which the hidden door is installed, the conventional hidden door for the hidden room does not consider or take into account any functionality other than the function of the hidden door itself (i.e., the function of concealing or hiding the hidden room), the overall aesthetic design of the wall or partition including the hidden door (i.e., the design of the wall or partition as a whole), or the aesthetic design of the hidden door itself (i.e., the design of the hidden door). Therefore, the inventors have considered these points in a comprehensive manner and conducted intensive research and studies, and as a result, have conceived of the present invention and completed the present invention.

[0016] [Problem of the present invention] Therefore, the present invention assumes the worst case scenario and aims to provide a security door structure and a wall-like structure having a security door structure, which conceals to the greatest extent possible the existence of a hidden door leading to a hidden room, and which can prevent to the greatest extent possible the opening of the hidden door even if the existence of the hidden door becomes known to anyone other than the administrator, thereby maximizing the security of the security room or security door, and further improving functionality other than the function of the security door itself (i.e. the function of concealing or concealing the security room), the overall aesthetic design of the wall lock structure and partition structure including the security door (i.e. the design of the entire wall structure or partition structure), and the aesthetic design of the security door itself (i.e. the design of the hidden door). [Means for solving the problem]

[0017] A security door structure according to a first aspect of the present invention includes an outer frame having a predetermined front-rear dimension, a first security door attached to the front side of the outer frame in the front-rear direction so as to be freely opened and closed by opening outward, a second security door attached to the rear side of the outer frame in the front-rear direction so as to be freely opened and closed by opening inward, a first locking device for locking and unlocking the first security door to the outer frame, and a second locking device for locking and unlocking the second security door to the outer frame. The first security door has a frame having a frame shape corresponding to the frame shape of the front surface of the outer frame, and a functional mirror panel that shields the entire front surface of the frame and has at least a function as a half mirror. The second security door has a back panel having an outer shape corresponding to the opening shape of the rear end of the outer frame, and a furniture structure provided on the front surface of the back panel. Furthermore, a lighting device for illuminating the furniture structure is provided in the internal space of the outer frame.

[0018] In the security door structure according to the second aspect of the present invention, the first locking device is an electromagnetic locking device. The electromagnetic locking device has an electromagnetic adsorption block body fixed to the front end of the outer frame, a strike plate attached to the inner surface of the frame of the first security door at a position facing the electromagnetic adsorption block body, and a control device for controlling the electromagnetic adsorption operation of the electromagnetic adsorption block body. The control device of the electromagnetic locking device always maintains the generation of electromagnetic adsorption force by the electromagnetic adsorption block body, detects an object that has entered a predetermined detection area in a non-contact manner, and stops the generation of electromagnetic adsorption force by the electromagnetic adsorption block body. The control device of the electromagnetic locking device is freely positioned in a predetermined position of a constantly dark space area that is a closed space area provided outside the outer frame and is shielded by the functional mirror plate to always maintain its function as a dark area.

[0019] The security door structure according to a third aspect of the present invention further comprises a mechanical locking device, wherein the second locking device comprises a rod-shaped key cylinder lock fixed at a predetermined position on the rear surface of the back plate of the second security door, and a rod-shaped key for locking and unlocking the rod-shaped key cylinder lock, and a key insertion hole for inserting the rod-shaped key into a keyhole in a cylinder part of the rod-shaped key cylinder lock is formed at a position on the back plate of the second security door where the cylinder part is located. The lighting device has a predetermined lighting range in the internal space within the outer frame, and is set to optical characteristics such that the lighting limit of the lighting range is a predetermined distance forward of the front surface of the back plate in the internal space of the outer frame.

[0020] A wall-like structure according to a fourth aspect of the present invention comprises at least a portion of the above-mentioned security structure and is fixedly positioned between a pair of walls in the interior space of a room of a building so as to completely shield the space formed between the pair of walls and the ceiling and floor corresponding to the portion of the pair of walls. Effect of the Invention

[0021] The security door structure and wall-like structure having a security door structure of the present invention, assuming the worst case scenario, conceals to the greatest extent possible the existence of a hidden door leading to a hidden room, and even if the existence of the hidden door becomes known to anyone other than the administrator, is able to prevent the opening of the hidden door to the greatest extent possible, thereby maximizing the security of the security room or security door, and further improving functionality other than the function of the security door itself (i.e. the function of concealing or concealing the security room), the overall aesthetic design of the wall lock structure and partition structure including the security door (i.e. the design of the entire wall structure or partition structure), and the aesthetic design of the security door itself (i.e. the design of the hidden door).

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0023] Hereinafter, modes for carrying out the present invention (hereinafter, referred to as embodiments) will be described. Note that, throughout the embodiments, the same members, elements or portions are designated by the same reference numerals, and the description thereof will be omitted.

[0024] {First embodiment} A wall structure according to a first embodiment of the present invention (i.e., a wall structure provided with a security door according to the first embodiment) will be described with reference to Fig. 1 to Fig. 36. Note that the "wall structure provided with a security door" according to the present invention may also be referred to as a "partition structure provided with a security door" or a "partition wall structure provided with a security door" in the description of the present invention.

[0025] FIG. 1 is a plan view showing an entire wall structure (a wall structure equipped with a security door) according to embodiment 1 of the present invention, and is a plan view (top view) showing a schematic view of the wall structure placed inside a specified room of a building.

[0026] [Installation of wall structure] As shown in FIG. 1, the wall structure WS equipped with the security door according to the first embodiment is fixedly installed inside a predetermined room (i.e., an indoor space) of a building by retrofitting or the like so as to divide the indoor space into a first indoor space S1 and a second indoor space S2. Here, the indoor space is usually a planar rectangular indoor space surrounded on all four sides by four straight walls. Therefore, the wall structure WS equipped with the security door is usually fixedly installed between a pair of opposing walls by retrofitting or the like so as to completely block the space between the pair of walls over the entire space (full width and full height) between the pair of walls, that is, to completely shield the rectangular surface formed by the pair of walls and the ceiling and floor of the pair of walls as viewed from the front. In the first embodiment, as shown in FIG. 1, the interior space of the room is partitioned by a front wall W1, a rear wall W2, a left wall W3, and a right wall W4 (as well as a ceiling (ceiling wall) CL and a floor (floor wall) FL shown in FIGS. 8 and 9), and the wall structure WS equipped with a security door is fixed and installed by retrofitting work or the like between the left wall W3 and the right wall W4 so as to completely block the space between the left wall W3 and the right wall W4 as a pair of opposing walls over the entire space (full width and full height) among the four walls (i.e., the front wall W1, the rear wall W2, the left wall W3, and the right wall W4) of the planar rectangular interior space, that is, to completely shield the rectangular surface formed by the left wall W3 and the right wall W4 and the ceiling CL and floor FL (of the left wall W3 and right wall W4 portion) as seen from the front. The front wall is provided with a door WD that can be opened and closed for entering and leaving the interior space of the room.

[0027] [Installation of wall-like structure (another example)] Here, in order to form an interior space of a room in a building, including special cases, it is necessary to arrange and connect at least three or more walls adjacent to each other. Therefore, it is assumed that the interior space of a room in a building may be, for example, a planar triangular space consisting of three walls, a planar pentagonal space consisting of five walls, a planar hexagonal space consisting of six walls, or a planar octagonal space consisting of eight walls, and the wall structure equipped with the security door according to the present invention is configured to be able to accommodate these interior spaces (shapes other than a planar rectangular shape). In other words, the wall-like structure equipped with the security door of the present invention is fixed and installed by retrofitting work or the like between a pair of opposing walls (for example, a pair of opposing parallel walls in the case of a planar hexagonal interior space) or a pair of adjacent walls (for example, a pair of adjacent walls in the case of a planar triangular or hexagonal interior space) among the walls (three or more specified multiple) of an interior space having a planar shape other than a planar rectangular shape, so as to completely block the space between the pair of walls over the entire space (total width and total height), i.e., to completely shield the rectangular surface as viewed from the front formed by the pair of walls and the ceiling CL and floor FL of the pair of walls.

[0028] [Components of wall structure (plan view)] As shown in Fig. 1, the wall structure WS equipped with the security door according to the first embodiment includes a security door structure SS (sometimes referred to as a "security door unit" in the description of the present invention) as a first unit structure, a display structure DS (sometimes referred to as a "display unit" in the description of the present invention) as a second unit structure, a wardrobe structure RS (sometimes referred to as a "wardrobe unit" in the description of the present invention) as a third unit structure, and a cabinet structure CS (sometimes referred to as a "cabinet unit" in the description of the present invention) as a fourth unit structure. As shown in Fig. 1, the wall structure WS equipped with the security door is configured by integrally assembling (or assembling) the security door structure SS, the display structure DS, the wardrobe structure RS, and the cabinet structure CS so that they are aligned in a row (in a straight line) from the left without any gaps, thereby forming an integral wall structure as a whole.

[0029] <Frame structure of wall-like structure> Here, the wall structure WS with the security door can be formed by assembling a metal frame (e.g., aluminum frame) in the form of a straight bar having a rectangular cross section in correspondence with the outer contour of the wall structure, and in the internal space of the outer frame, the security door structure SS, the display structure DS, the wardrobe structure RS, and the cabinet structure CS can be assembled in a line (straight line) from the left to the right in the portion corresponding to the security door structure SS, the portion corresponding to the display structure DS, the portion corresponding to the wardrobe structure RS, and the portion corresponding to the cabinet structure CS, respectively. For example, as shown in Figs. 33 to 36, the wall structure WS with the security door can be formed by assembling a metal frame (e.g., aluminum frame) MF in the form of a straight bar having a rectangular cross section in correspondence with the outer contour of the wall structure, and the outer frame of the wall structure can be formed.

[0030] [Components of wall structure (front view)] As shown in Figure 14, the wall structure WS equipped with the security door of embodiment 1 has a first storage box B1, a second storage box B2, a third storage box B3, and a fourth storage box B4 (consisting of storage boxes with a door that can be opened and closed freely at the front) arranged on the upper side of the security door structure SS, the upper and lower sides of the display structure DS, and the upper sides of the wardrobe structure RS and cabinet structure CS, respectively.

[0031] That is, the first storage box B1 is positioned closely above the security door structure SS and has the same width dimension (left-right dimension) as the security door structure SS, a predetermined height dimension, and is formed in the shape of a cubic box having the same depth dimension as the security door structure SS.

[0032] The second storage box B2 is arranged in close contact with the upper side of the display structure DS, and has the same width (left-right dimension) as the width (left-right dimension) of the display structure DS, a predetermined height, and is formed in a cubic box shape having the same depth as the depth of the display structure DS. In the example of Fig. 14, the second storage box B2 is configured as a total of 12 second storage boxes B2 in two tiers, one above the other, and six tiers, and the entire second storage box B2 is arranged in close contact with the upper side of the display structure DS, and has the same width (left-right dimension) as the width (left-right dimension) of the display structure DS, a predetermined height, and is formed in a cubic box shape having the same depth as the depth of the display structure DS (i.e., the cubic box-shaped space is divided into a total of 12 small spaces in two tiers, one above the other, and six tiers,). The specified height dimension of the second storage box B2 (consisting of a total of 12 small boxes) is set to the same dimension as the distance from the upper end position of the display structure DS to the upper end position of the first storage box B1 above the security door structure SS, so that the upper end of the second storage box B2 is flush with the upper end of the first storage box B1 above the security door structure SS.

[0033] The third storage box B3 is arranged closely below the display structure DS, and has the same width (left-right dimension) as the width (left-right dimension) of the display structure DS, a predetermined height, and a cubic box shape with the same depth as the depth of the display structure DS. In the example of Fig. 14, the third storage box B3 is configured as a total of six third storage boxes B3, with one upper and one lower stage and six left and right stages, and the entire third storage box B3 is arranged closely below the display structure DS, and has the same width (left-right dimension) as the width (left-right dimension) of the display structure DS, a predetermined height, and a cubic box shape with the same depth as the depth of the display structure DS (i.e., the cubic box-shaped space is divided into a total of six small spaces, with one upper and lower stage and six left and right stages). The specified height dimension of the third storage box B3 (consisting of a total of six small boxes) is set to be the same as the distance from the lower end position of the display structure DS to the lower end position of the security door structure SS, so that the lower end of the third storage box B3 is flush with the lower end of the security door structure SS.

[0034] The fourth storage box B4 is arranged closely to the upper side of the wardrobe structure RS and the cabinet structure CS, and has the same width dimension (left-right dimension) as the total dimension of the width dimension (left-right dimension) of the wardrobe structure RS and the cabinet structure CS, a predetermined height dimension, and is formed in a cubic box shape having the same depth dimension as the display structure DS. In the example of Fig. 14, the fourth storage box B4 is configured as a total of two fourth storage boxes B4, with two levels, one on the top and one on the bottom, and one on the left and right, and the entire fourth storage box B4 is arranged closely to the upper side of the wardrobe structure RS and the cabinet structure CS, and has the same width dimension (left-right dimension) as the total dimension of the width dimension (left-right dimension) of the wardrobe structure RS and the cabinet structure CS, a predetermined height dimension, and is formed in a cubic box shape having the same depth dimension as the depth dimension of the wardrobe structure RS and the cabinet structure CS (i.e., the cubic box-shaped space is divided into a total of two small spaces, with two levels, one on the top and bottom, and one on the left and right). The specified height dimension of the fourth storage box B4 (consisting of a total of two small boxes) is set to the same dimension as the distance from the upper end positions of the wardrobe structure RS and cabinet structure CS to the upper end position of the first storage box B1 above the security door structure SS, so that the upper end of the fourth storage box B4 is flush with the upper end of the first storage box B1 above the security door structure SS.

[0035] [Outline of wall structure] In this way, the wall structure WS equipped with the security door according to the first embodiment is configured such that the upper end of the first storage box B1, the upper end of the second storage box B2, and the upper end of the fourth storage box B4, which constitute the upper end contour, are all flush with each other among the overall outer contours. Also, the wall structure WS equipped with the security door according to the first embodiment is configured such that the lower end of the security door structure SS, the lower end of the third storage box B3, the lower end of the wardrobe structure RS, and the lower end of the cabinet structure CS, which constitute the lower end contour, are all flush with each other among the overall outer contours. Also, the wall structure WS equipped with the security door according to the first embodiment is configured such that the left end of the first storage box B1, which constitutes the left end contour, and the left end of the security door structure SS, which constitutes the left end contour, are all flush with each other among the overall outer contours. Also, the wall structure WS equipped with the security door according to the first embodiment is configured such that the right end of the fourth storage box B4, which constitutes the right end contour, and the right end of the cabinet structure CS, which constitutes the right end contour, are all flush with each other among the overall outer contours. That is, the wall structure WS equipped with the security door according to embodiment 1 is configured so that the outer ends of the components constituting the overall outer contour are all flush with each other, and the overall outer contour is formed into a perfect rectangle. As a result, the wall structure WS equipped with the security door according to embodiment 1 is formed so that the overall outer contour is a rectangle (horizontally elongated rectangular shape) (the same as the outer contour of the surface) that completely shields the rectangular surface formed by the left wall W3 and right wall W4 and the ceiling CL and floor FL (of the left wall W3 and right wall W4 portions) when viewed from the front.

[0036] [Dividing interior space by wall structures] As shown in FIG. 1, in the first embodiment, the wall structure WS having the security door is fixed between the left wall W3 and the right wall W4 by retrofitting or the like so as to completely block the space between the left wall W3 and the right wall W4 over the entire space (full width and full height) between the left wall W3 and the right wall W4 in a planar rectangular indoor space, that is, to completely shield the rectangular surface as viewed from the front formed by the left wall W3 and the right wall W4 and the ceiling CL and floor FL (of the left wall W3 and the right wall W4). Therefore, the indoor space is divided by the wall structure WS having the security door into a first space S1 located at the front side of the indoor space (i.e., the side closer to the front wall W1) and a second space S2 located at the rear side of the indoor space (i.e., the side closer to the rear wall W2). In the first embodiment, the second space S2 is completely hidden (or shielded) from the first space S1 by the wall structure WS having the security door, forming the security room of the present embodiment. That is, when a wall structure WS having a security door according to the first embodiment is provided in a certain room in a certain building, only the manager of the building (for example, the person with the highest position among the residents of the building, for example, the person equivalent to the so-called head of the household) is made to know the fact, and the fact is kept secret so that the others are not informed of it. In this way, only the manager knows that the wall structure WS in the certain room is not a normal wall (a wall equivalent to the rear wall of a normal room), but a wall for forming a security room behind it. Therefore, a person other than the manager who enters the certain room (where the wall structure WS having a security door is provided) recognizes that only the first space S1 located on the front side of the indoor space of the certain room (i.e., the side closer to the front wall W1) is the entire indoor space (i.e., mistakenly recognizes the first space S1 as the entire indoor space), and is completely unable to recognize that there is a second space S2, which is a security room, on the rear side of the first space S1, sandwiched between the wall structure WS.

[0037] In particular, the wall structure WS equipped with the security door is fixed between the left wall W3 and the right wall W4 so as to completely shield the rectangular surface formed by the left wall W3 and the right wall W4 and the ceiling CL and floor FL (of the left wall W3 and the right wall W4) as viewed from the front. Therefore, such a wall structure WS equipped with a security door cannot be recognized as the rear wall of the specific room (more specifically, the rear wall to which the security door structure SS, the display structure DS, the wardrobe structure RS, the cabinet structure CS, the first storage box B1, the second storage box B2, the third storage box B3, and the fourth storage box B4 are integrally assembled) by anyone other than the administrator. Therefore, a person other than the administrator who enters the specific room recognizes that only the first space S1 located at the front side of the indoor space of the specific room is the entire indoor space, and cannot recognize at all that there is a second space S2, which is a security room, at the rear of the first space S1, sandwiched between the wall structure WS.

[0038] [Frame structure of wall structure] First, the frame structure of the wall structure WS will be described. As shown in Figs. 32 to 35, the wall structure WS has an overall structure frame (overall structure frame) 100 for a framework structure for forming the overall framework structure of the wall structure WS. The overall structure frame 100 is made of a metal material frame such as an aluminum frame. The overall structure frame 100 also has an outer frame portion 101. The overall structure frame 100 further has a support frame 102 for supporting a display 112 in the internal space of the display structure DS. The support frame 102 supports the display 112 by fastening and fixing the rear surface of the display 112 by bolting or the like, and is fixed to a portion of the overall structure frame 100 corresponding to the display 112 so as to extend vertically. In the example of Figs. 21 to 31, three support frames 102 are provided, but two or four or more support frames 102 may also be provided.

[0039] [Structures other than security door structures] Next, the structures other than the security door structure SS (that is, the display structure DS, the wardrobe structure RS, and the cabinet structure CS) will be described with reference to Figs. 1, 14, 20 to 31, and 32 to 35.

[0040] The display structure DS, the wardrobe structure RS, and the cabinet structure CS, which are structures other than the security door structure SS, each have a frame-shaped or framework-shaped outer frame, and have an internal space for storing or accommodating predetermined storage items or containers. The display structure DS, the wardrobe structure RS, and the cabinet structure CS each have a predetermined opening at the front of the internal space, and a hinged door is attached to the opening so that it can be opened and closed freely outward.

[0041] [Display structure] As shown in Figs. 32 and 33, the display structure DS is provided with a door 110, which is an outward-opening hinged door, at an opening 115 provided at the front side (first space S1 side) of the internal space. The door 110 is attached so that it can be opened and closed freely with a hinge at the upper end, and is configured so that the door 110 rotates upward to open the opening 115 by lifting the lower end upward, and rotates downward to close the opening 115 by pushing the lower end downward. The door 110 may also be provided with a damper to assist the opening and closing operation. The door 110 of the display structure DS is composed of a frame similar to the frame of the front door 20 of the security structure SS described later (i.e., a frame similar to the frame 21 of the front door 20 described later) and a functional panel 111 similar to the functional panel 22 of the front door 20 of the security structure SS. A display 112 is fixed to a predetermined position (for example, the central region) of the internal space of the display structure DS via a support frame 102 or the like. In this fixed state, the screen surface (front surface of the screen) of the display 112 is closely arranged on the rear surface of the functional panel of the door 110 in the closed state. The display 112 can be composed of, for example, a liquid crystal display (LCD), a plasma display (PDP), an organic electroluminescence display (OLED), or the like.

[0042] The display structure DS is also provided with an upper frame (upper frame) 113 for connecting and fixing the upper end of the support frame 102. The upper frame 113 may be a framework-like frame, a flat support plate, or may be formed by the lower plate of the small box below the second storage box B2. The display structure DS is also provided with a lower frame (lower frame) 114 for connecting and fixing the lower end of the support frame 102. The lower frame 114 may be a framework-like frame, a flat support plate, or may be formed by the upper plate of the small box of the third storage box B3.

[0043] In the internal space of the display structure DS, a first storage section 120 and a second storage section 130 are provided on both the left and right sides of the area in which the display 112 is disposed, respectively.

[0044] The first storage section 120 is disposed on the left end side of the display structure DS, that is, in the vicinity of the security door structure SS. The first storage section 120 has a frame 121 and a shelf board 122. The upper end of the frame 121 of the first storage section 120 can be formed by the lower board of the small box on the lower side of the second storage box B2. The shelf board 122 of the first storage section 120 can be a single-stage as shown in Figs. 21 to 23, 30 and 31, but can also be a two-stage stage as shown in Figs. 24 to 29, or can be three or more stages. The shelf board 122 and the bottom board of the first storage section 120 can be used as a support board for the control box 80 of the security door structure SS described later.

[0045] On the other hand, the second storage section 130 is disposed on the right end side of the display structure DS, that is, at a position separated from the security door structure SS (and close to the wardrobe structure RS). The second storage section 130 also has a frame 131. The upper end of the frame 131 of the second storage section 130 can also be formed by the lower plate of the small box at the lower side of the second storage box B2. As shown in Figs. 28 and 29, the frame 131 of the second storage section 130 may be provided with a shelf similar to the shelf 122 of the first storage section 120. In this case, the shelf can be one-tiered, two-tiered, or three or more tiered. The bottom plate and the shelf of the second storage section 130 can also be used as support plates for the control box 80 of the security door structure SS described later.

[0046] [Wardrobe structure] The wardrobe structure RS is fitted with a door 140, which is an outward-opening hinged door, at an opening provided at the front side (first space S1 side) of the internal space. The door 140 is fitted so that it can be opened and closed freely with a hinge at the left end, and is adapted to rotate forward to open the opening by pulling the right end (for example, a handle attached to the right end edge) forward, and rotate backward to close the opening by pushing the right end backward. The door 140 of the wardrobe structure RS is made up of a frame similar to the frame of the front door 20 of the security structure SS described later (i.e., a frame similar to the frame 21 of the front door 20 described later) and a functional panel 141 similar to the functional panel 22 of the front door 20 of the security structure SS described later.

[0047] [Cabinet structure] The cabinet structure CS is fitted with a door 150, which is a hinged door that opens outwards, at an opening provided at the front side (first space S1 side) of the internal space. The door 150 is fitted so that it can be opened and closed freely with a hinge at the right end, and is adapted to rotate forward to open the opening by pulling the left end (for example, a handle attached to the left edge) forward, and rotate backward to close the opening by pushing the left end backward. The door 150 of the cabinet structure CS is made up of a frame similar to the frame of the front door 20 of the security structure SS described later (i.e., a frame similar to the frame 21 of the front door 20 described later) and a functional panel 151 similar to the functional panel 22 of the front door 20 of the security structure SS described later.

[0048] [Security door structure] Next, the security door structure SS will be described in detail with reference to FIGS. 2 to 8 and 9 to 13. FIG.

[0049] <Overall structure of security door structure> As shown in FIG. 2, the security door structure SS includes an outer frame 10, a front door 20 serving as a first security door, and a rear door 30 serving as a second security door.

[0050] <Outer frame> The outer frame 10 is composed of an upper plate (sometimes called the "upper frame") 11, a lower plate (sometimes called the "bottom plate" or "footrest") 12, a left plate (sometimes called the "left vertical frame") 13, and a right plate (sometimes called the "right vertical frame") 14. The outer frame 10 is formed by fixedly joining the upper plate 11, the lower plate 12, the left plate 13, and the right plate 14 to each other at their longitudinal end edges, so as to have a predetermined rectangular frame shape (for example, a rectangular frame shape that is long vertically) when viewed from the front. The upper plate 11, the lower plate 12, the left plate 13, and the right plate 14 are each formed from a predetermined material such as wood material, so as to have a rectangular flat plate shape of a predetermined length, width, and thickness.

[0051] Here, in order to configure the outer frame 10 into the predetermined rectangular frame shape, the upper plate 11, the lower plate 12, the left plate 13, and the right plate 14 can be joined in various ways as long as the outer frame 10 has the predetermined rectangular frame shape. For example, as shown in the plan views of Figures 2 to 7 and the side views of Figures 10 to 13, the upper plate 11, the left plate 13, and the right plate 14 have the same width dimension (front-to-back dimension to depth dimension). On the other hand, the lower plate 12 has a width dimension (front-to-back dimension to depth dimension) that is smaller by a predetermined dimension than the width dimensions (front-to-back dimension to depth dimension) of the upper plate 11, the left plate 13, and the right plate 14. The outer frame 10 can be formed into the predetermined rectangular frame shape by arranging the left plate 13 and the right plate 14 parallel to each other so that they are spaced apart from each other (the distance between their respective outer surfaces) the same distance as the length dimension of the upper plate 11 and extend vertically in the up-down direction, placing both longitudinal ends of the upper plate 11 on the upper end surfaces of the left plate 13 and the right plate 14, respectively fixing the lower surfaces of both longitudinal end edges of the upper plate 11 to the upper end surfaces of the left plate 13 and the right plate 14, respectively, and fixing both longitudinal end faces (the right end face and the left end face) of the lower plate 12 to the inner faces of the lower end edges of the left plate 13 and the right plate 14, respectively. That is, in this case, the lower plate 12 has the same length dimension as the distance between the inner faces of the lower ends of the left plate 13 and the right plate 14 fixed to the lower surface of the upper plate 11. In this case, the lower plate 12 has a depth dimension that is smaller than the depth dimensions of the upper plate 11 and the left plate 13 and right plate 14 by a predetermined dimension, and therefore, in the outer frame 10, a gap portion (a portion where the lower plate 12 is not present) of the same dimension as the predetermined dimension is formed behind the lower plate 12.

[0052] Alternatively, in order to configure the outer frame 10 into the predetermined rectangular frame shape, the following configuration may be used. For example, in this case, the upper plate 11, the left plate 13, and the right plate 14 have the same width dimension (front-to-back dimension and depth dimension). On the other hand, the lower plate 12 has a width dimension (front-to-back dimension and depth dimension) that is smaller than the width dimensions (front-to-back dimension and depth dimension) of the upper plate 11, the left plate 13, and the right plate 14 by a predetermined dimension. The outer frame 10 can be formed into the specified rectangular frame shape by arranging the left and right plates 13, 14 parallel to each other so that they are spaced apart from each other (the distance between their respective inner surfaces) the same distance as the length dimension of the upper plate 11 and extend vertically in the up-down direction, and then fixing both longitudinal end faces (right and left end faces) of the upper plate 11 to the inner surfaces of the upper edges of the left and right plates 13, 14, respectively, and fixing both longitudinal end faces (right and left end faces) of the lower plate 12 to the inner surfaces of the lower edges of the left and right plates 13, 14, respectively.

[0053] <Front door> As shown in Figures 2 to 7, the front door 20 as the first hidden door (or first security door) is attached to the front end of the outer frame 10 (more precisely, the front edge of the left side panel 13) via a sliding hinge 25 so as to be able to open and close freely outwardly with respect to the outer frame 10 (more precisely, between a closed state in which it is in close contact with the front end face of the outer frame 10 consisting of the front end faces of the upper panel 11, the lower panel 12, the left side panel 13, and the right side panel 14, and an open state in which it moves away forward while increasing the inclination angle from the front end face to the front end face).

[0054] In detail, the front door 20, as shown in Fig. 3, Fig. 11 to Fig. 13, and Fig. 15 to Fig. 17, is composed of a frame 21 and a functional panel 22. As shown in Fig. 15 to Fig. 17, the frame 21 is integrally formed from a frame material made of a metal material such as aluminum so as to have a predetermined rectangular frame shape identical to the shape of the front surface (exposed surface at the front end) of the outer frame 10. That is, the frame shape of the frame 21 is formed to have the same shape as the rectangular frame shape of the outer frame 10, which is composed of the front end surface of the upper plate 11, the front end surface of the lower plate 12, the front end surface of the left plate 13, and the front end surface of the right plate 14. Therefore, the outer dimensions of the frame 21 (the rectangular dimensions of the outer peripheral edge that becomes the outer peripheral contour) are the same as the outer dimensions of the outer frame 10 (the rectangular dimensions of the outer peripheral edge that becomes the outer peripheral contour). That is, the height dimension (length dimension) of the frame 21 is the same as the height dimension (length dimension) of the outer frame 10, and the left-right dimension (width dimension) of the frame 21 is the same as the left-right dimension (width dimension) of the outer frame 10. As a result, when the front door 20 is attached to the front end of the outer frame 10 and is completely closed relative to the outer frame 10, the rear surface of the frame 21 is in close contact with the front surface of the outer frame 10 in a completely aligned state, as shown in Figures 2 to 7, 10 to 13, and 15 to 17. That is, at this time, the outer peripheral edge (outer edge) of the frame 21 and the outer peripheral edge (outer edge) of the outer frame 10 completely match, and the inner peripheral edge (inner edge) of the frame 21 and the inner peripheral edge (inner edge) of the outer frame 10 completely match. The security door structure SS has external dimensions and an external shape that allow it to be tightly fitted and fixed into an opening that has a predetermined rectangular shape (a vertically extending rectangular shape) in front view and is provided in a portion of the wall structure WS where the security door structure SS is to be disposed, and therefore the front door 20 also has external dimensions and an external shape that allow it to be tightly fitted and fixed into this opening. Similarly, the outer frame 10 also has external dimensions and an external shape that allow it to be tightly fitted and fixed into this opening.

[0055] <Structure of functional end plate> In the front door 20, the functional panel 22 is integrally fixed to the front surface of the frame 21 by adhesion or the like. The functional panel 22 is formed to have a predetermined rectangular flat plate shape that is the same as the outer shape (outer peripheral contour shape) of the frame 21. That is, the dimensions of the functional panel 22 are the same as the outer dimensions of the frame 21. That is, the height dimension (length dimension) of the functional panel 22 is the same as the height dimension (length dimension) of the frame 21, and the left-right dimension (width dimension) of the functional panel 22 is the same as the left-right dimension (width dimension) of the frame 21. That is, at this time, the outer peripheral edge (outer edge) of the functional panel and the outer peripheral edge (outer edge) of the frame 21 completely match. As a result, in the front door 20, the functional panel 22 completely shields the frame 21 from the front, which is the outside.

[0056] <Function of the functional panel 1> The functional mirror plate 22 has at least the same functions as a normal magic mirror, mirror glass, or half mirror, and when the amount of light incident on the functional mirror plate 22 is different on both sides of its thickness direction (the front or front side and the rear or back side), when the functional mirror plate 22 is viewed from the bright side (the side where a greater amount of light is incident on the functional mirror plate 22) which is one side of the thickness direction, the functional mirror plate 22 is viewed as a normal mirror (i.e., from the one side of the thickness direction, the functional mirror plate 22 becomes a mirror that reflects the scenery, people, etc. on the bright side), whereas when the functional mirror plate 22 is viewed from the dark side (the side where a lesser amount of light is incident on the functional mirror plate 22) which is the other side of the thickness direction, the functional mirror plate 22 is viewed as transparent glass (or at least translucent glass) (i.e., from the other side of the thickness direction, the functional mirror plate 22 becomes transparent or translucent glass that transmits the scenery, people, etc. on the bright side). For example, when the functional panel 22 is fixed to the frame 21 to form the front door 20, if the amount of incident light on one side in the thickness direction (e.g., the surface side of the front door 20) is large (for example, when the wall structure WS is placed in the interior space of the specific room to divide the interior space into a first space S1 and a second space S2, the lighting device in the first space S1 is turned on to make the amount of incident light from the first space S1 to the functional panel 22 a large amount of incident light from the lighting device, while the amount of light in the space within the outer frame 10 behind the front door 10 in the security door structure SS is less than the amount of incident light from the lighting device or is zero), the functional panel 22 may have a bright side (i.e., the functional When the functional mirror panel 22 is viewed from the first space S1 side, which is the outside of the front door 10 and where the amount of light incident on the functional mirror panel 22 is large, the functional mirror panel 22 is viewed as a normal mirror (i.e., from one side in the thickness direction, the functional mirror panel 22 is a mirror that reflects the scenery, people, etc. in the first space S1), whereas when the functional mirror panel 22 is viewed from the darker side in the thickness direction (the internal space side of the outer frame 10, which is the inside of the front door 10 and where the amount of light incident on the functional mirror panel 22 is small), the functional mirror panel 22 is viewed as transparent glass (or at least translucent glass) (i.e., from the other side in the thickness direction, the functional mirror panel 22 is transparent or translucent glass that transmits the scenery, people, etc. on the first space S1 side).As a result, for example, when the wall-like structure WS is placed in the interior space of the specific room and the interior space is divided into a first space S1 and a second space S2, if the lighting fixture in the first space S1 is turned on while the amount of light in the space within the outer frame 10 behind the front door 10 in the security door structure SS is set to, for example, zero, the functional mirror panel 22 functions as a normal mirror and its surface reflects the scenery, people, etc. in the first space S1, but does not transmit any images (components, parts, etc. exposed within the outer frame) in the space within the outer frame 10 behind the front door 10 to the outside (the first space S1 side).

[0057] <Camouflage of the front door's appearance (camouflage using the mirror function)> When there is an amount of incident light from the first space S1 (typically, when external light enters the first space S1 during the day or when illumination light from a lighting fixture enters the first space S1 at night), the functional mirror panel 22 realizes the same reflection function as a normal mirror (a function of displaying an inverted image by reflecting an image) as described above, and the front door 20 is visually recognized as a normal mirror, so that a person who enters the first space S1 only recognizes the front door 20 as a normal mirror. In particular, since the front door 20 completely shields the entire frame 21 with the functional mirror panel 22, the front surface of the front door 20 is recognized by a person who enters the first space S1 as a mirror caused by the functional mirror panel 22. That is, the front door 20 realizes an appearance camouflage function by the functional mirror panel 22, which prevents a person who enters the first space S1 from recognizing the front door 20 as a door and causes the person who enters the first space S1 to mistakenly recognize the front door 20 as a normal mirror.

[0058] <Function of the functional panel 2> In addition to the normal half mirror function, the functional panel 22 preferably has, for example, a touch sensor function or an electromagnetic wave transmission function (i.e., a function of smoothly transmitting electromagnetic waves from a non-contact sensor or the like without blocking or impeding them), and the functional panel 22 of the front door 20 of the security door structure SS of the first embodiment additionally has these functions. For example, as shown in FIG. 36, the functional panel 22 can be formed as a functional layer-added multi-layer structure functional panel 22 in which a touch sensor layer (e.g., a capacitive touch sensor layer) 22b and a dielectric layer 22c as a semi-transparent reflective film or semi-transparent reflective film are laminated on the back surface of a transparent substrate 22a of a predetermined thickness (e.g., a transparent glass substrate or protective glass plate of a predetermined thickness, or a transparent glass layer of a predetermined thickness). In this case, the touch sensor layer 22b provides the touch sensor function (through a control circuit or the like electrically connected to the touch sensor layer 22b). The dielectric layer 22c also provides an electromagnetic wave transmission function, that is, a function of smoothly transmitting electromagnetic waves from a non-contact sensor or the like without blocking or impeding them.

[0059] <Dielectric layer of functional mirror plate> In this case, the dielectric layer 22c of the functional mirror plate 22 can be, for example, a dielectric multilayer type dielectric layer 22c. This dielectric multilayer type dielectric layer 22c has a multilayer structure in which high refractive index layers (for example, high refractive index polymer layers) and low refractive index layers (for example, low refractive index polymer layers) are alternately stacked, and when visible light passes through the multilayer structure, a part of the visible light is reflected as a reflected light beam at the interface between the high refractive index polymer layer and the low refractive index polymer layer, and the other part is transmitted as a transmitted light beam. Here, in the case of forming a very thin reflective film on plate glass or organic glass such as acrylic to make it semi-transparent, as in the case of a normal one-way mirror or half mirror, if a metal film made of tin, silver, or the like is formed by plating or vapor deposition as the semi-transparent reflective film or semi-transparent reflective film, the semi-transparent reflective film or semi-transparent reflective film is made of metal, and therefore interferes with the electromagnetic waves of a non-contact sensor or the like, blocking or obstructing the electromagnetic waves. However, since the functional mirror plate 22 is made of a dielectric layer 22cga, which is a semi-transparent or semi-transparent reflective film, it does not interfere with the electromagnetic waves of a non-contact sensor, does not block or obstruct the electromagnetic waves, and transmits the electromagnetic waves smoothly, so that the intended function of the non-contact sensor can be realized well. In the case of a dielectric multi-layered type dielectric layer 22c, titanium oxide, niobium oxide, lanthanum oxide, tantalum oxide, zirconium oxide, silicon nitride, etc. can be used as the dielectric material of the high refractive index layer, and silicon oxide, aluminum oxide, magnesium fluoride, etc. can be used as the dielectric material of the low refractive index layer. In addition, the thickness dimension, number of layers (the number of layers of high refractive index layers and low refractive index layers), and material of the dielectric multi-layered type dielectric layer 22c can be appropriately designed according to the optical properties and physical properties required for the functional mirror plate 22.

[0060] <Rear door> As shown in Figs. 2 to 7, the rear door 30 as a second hidden door (or a second security door) is attached to the rear end side of the outer frame 10 (more precisely, at a predetermined position on the rear side spaced a predetermined distance forward from the rear end of the left side panel 13) via a hidden hinge 35 so as to be openable and closable inward relative to the outer frame 10 (more precisely, between a closed state in close contact with the rear end face of the lower panel 12 and an open state in which the rear end face moves away backward while increasing the inclination angle relative to the rear end face). The rear door 30 cooperates with the front door 20 to form a composite security door structure in the security door structure SS of this embodiment. The rear door 30 also functions as a security door for a file safe when the security of the front door 20 is breached.

[0061] In detail, the rear door 30, as shown in Fig. 2, Fig. 4 to Fig. 7, Fig. 10 to Fig. 13, and Fig. 15 to Fig. 19, is composed of a back panel 31 and a plurality of (four in the illustrated example) shelf panels 32. As shown in Fig. 19, the back panel 31 is formed of a plate material such as a wood material so as to have a predetermined rectangular flat shape that is the same as the opening shape formed by the lower surface of the upper panel 11 and the inner surfaces of the left panel 13 and the right panel 14 on the rear side of the outer frame 10. That is, the outer shape of the back panel 31 (the overall shape of the outer peripheral edge) is formed to be the same as the rectangular shape formed by the lower surface of the upper panel 11, the inner surface of the left panel 13, and the inner surface of the right panel 14 in the outer frame 10. Therefore, the outer dimensions of the back panel 31 (the dimensions of the rectangular shape of the outer peripheral edge that becomes the outer peripheral outline) are the same as the dimensions of the rectangle formed by the lower surface of the upper panel 11, the inner surface of the left panel 13, and the inner surface of the right panel 14 in the outer frame 10. That is, the height dimension (length dimension) of the back panel 31 is the same as the height dimension (length dimension) of a rectangle formed by the lower surface of the upper panel 11, the inner surface of the left panel 13, and the inner surface of the right panel 14 in the outer frame 10, and the left-right dimension (width dimension) of the back panel 31 is the same as the left-right dimension (width dimension) of a rectangle formed by the lower surface of the upper panel 11, the inner surface of the left panel 13, and the inner surface of the right panel 14 in the outer frame 10. As a result, when the rear door 30 is attached to the rear end side of the outer frame 10 and is completely closed relative to the outer frame 10, the outer peripheral surface (upper surface and left and right side surfaces) of the back panel 31 is in approximately intimate contact (i.e., intimate contact with a small gap) with the lower surface of the upper panel 11, the inner surface of the left panel 13, and the inner surface of the right panel 14 at corresponding rear positions of the outer frame 10, as shown in Figures 2 to 7, 10 to 13, and 15 to 19. At this time, the lower end of the back panel 31 completely coincides with the lower end of the outer frame 10 (i.e., the lower ends of the left panel 13 and right panel 14, and the lower surface of the lower panel 12). Also, at this time, the lower edge portion of the front surface of the back panel 31 (the portion corresponding to the rear end surface of the lower panel 12) is in close contact with the rear end surface of the lower panel 12 and is prevented from rotating further forward, so that the lower panel 12 (more precisely, the rear end surface of the lower panel 12) exerts the function of preventing the rear door 30 from closing excessively.

[0062] <Function of concealing or shielding the rear door by the front door> As described above, when there is an amount of incident light from the first space S1 (typically, when external light enters the first space S1 during the day or when illumination light from a lighting fixture enters the first space S1 at night), the functional mirror panel 22 realizes the same reflection function as a normal mirror (a function of displaying an inverted image by reflecting an image) and the front door 20 is visually recognized as a normal mirror, so that a person who enters the first space S1 only recognizes the front door 20 as a normal mirror. In particular, since the front door 20 completely shields the entire frame 21 with the functional mirror panel 22, the front surface of the front door 20 is recognized by a person who enters the first space S1 as a mirror due to the functional mirror panel 22. That is, the front door 20 realizes an appearance camouflage function by the functional mirror panel 22, which prevents a person who enters the first space S1 from recognizing it as a normal door and causes them to mistake it for a normal mirror. At the same time, because the functional panel 22 of the front door 20 functions as a normal mirror in this manner, it completely shields or conceals the members and parts of the security door structure SS arranged behind the front door 20, completely preventing a person who has entered the first space S1 from viewing the back panel 31 and shelf 32 of the rear door 30 inside the outer frame 10. In other words, the front door 20, by using the functional panel 22, completely prevents a person who has entered the first space S1 from viewing the rear door 30, thereby achieving a concealing or shielding function that completely conceals or shields the existence of the rear door 30.

[0063] <Internal lighting (provides the function of an internally illuminated display shelf) 3 to 7, 11 to 13, 18, and 19, in the internal space of the outer frame 10, in the space forward of the back panel 31 of the rear door 30, LED line lighting fixtures 41 and 42, which are examples of interior lighting (interior lighting type) lighting fixtures or lighting devices, are fixedly disposed in pairs on the inner surface of the left panel 13 and the inner surface of the right panel 14, respectively. In detail, the LED line lighting fixture 41 is fixedly attached (i.e., so as not to shift position when in use) to the inner surface of the left panel 13 at a position close to the front end of the left panel 13 and spaced a predetermined distance rearward from the front end of the left panel 13 by being embedded in the left panel 13 (preferably so as to be removable and replaceable as required). Moreover, the LED line lighting device 42 is embedded in the right plate 14 (preferably so as to be removable and replaceable as required) and fixedly attached (i.e. so as not to shift position when in use) at a position close to the front end of the right plate 14 on the inner surface of the right plate 14 and spaced a predetermined distance rearward from the front end of the right plate 14. The distance between the LED line lighting device 41 and the front end of the left plate 13 and the distance between the LED line lighting device 42 and the front end of the right plate 14 are set to be the same.

[0064] The lighting fixtures consisting of the LED line lighting fixtures 41 and 42 can have a dimming function (light amount adjustment function) that adjusts the amount of light (through a predetermined electrical or electronic control device). Also, the lighting fixtures consisting of the LED line lighting fixtures 41 and 42 can have a color adjustment function that changes the illumination color.

[0065] As shown in FIG. 14, when the LED line lighting fixtures 41 and 42 are turned on by an external control device (for example, a remote-controlled lighting controller) (i.e., when the LED line lighting fixtures 41 and 42 are turned on to be in an illuminated state), the space in front of the back panel 31 of the rear door 30 in the internal space of the outer frame 10 is illuminated by the illumination light from the LED line lighting fixtures 41 and 42. As a result, in the internal space of the outer frame 10, the shelf 32 protruding forward from the back panel 31 of the rear door 30 is illuminated in a manner according to the amount of light and the illumination range of the illumination light. Also, in this illuminated state, a predetermined amount of light due to the illumination light from the LED line lighting fixtures 41 and 42 is emitted forward from the rear side of the functional panel 22 of the front door 20, enters the functional panel 20 as the predetermined amount of light, and transmits the functional panel 20 as the predetermined amount of light.

[0066] <Function when the internal light is off> Here, as described above, when the wall structure WS is placed in the interior space of the specific room and the interior space is divided into a first space S1 and a second space S2, if the lighting fixtures in the first space S1 are turned on while the amount of light in the space within the outer frame 10 behind the front door 10 in the security door structure SS is set to zero, that is, when the LED line lighting fixtures 41 and LED line lighting fixtures 42 are turned off by an external control device (i.e., when the LED line lighting fixtures 41 and LED line lighting fixtures 42 are turned off and set to a non-illuminated state), the space in front of the back panel 31 of the rear door 30 in the internal space of the outer frame 10 becomes an unlit space (i.e., a completely dark space where the amount of light in that space is zero). In this case, the LED functional mirror panel 22 functions as a normal mirror, and its surface reflects the scenery and people in the first space S1, but does not transmit any images (such as members and parts exposed in the outer frame) in the space inside the outer frame 10 behind the front door 10 to the outside (the first space S1 side). Therefore, even when there is an amount of incident light from the first space S1 (typically, when outside light enters the first space S1 during the day or illumination light from a lighting fixture enters the first space S1 at night), as described above, the functional mirror panel 22 realizes the exact same reflection function as a normal mirror (the function of inverting an image by reflecting an image) and is visually recognized as a normal mirror, so that a person who enters the first space S1 only recognizes the front door 20 as a normal mirror.

[0067] <Interior lighting function when the interior lighting is on> On the other hand, when the wall structure WS is placed in the interior space of the specific room to divide the interior space into a first space S1 and a second space S2, and the lighting fixtures in the first space S1 are turned on while the amount of light in the space within the outer frame 10 behind the front door 10 in the security door structure SS is set to a predetermined amount of light (for example, an amount of light equal to or greater than the amount of light from the first space S1), that is, when the LED line lighting fixtures 41 and LED line lighting fixtures 42 are turned on by an external control device (i.e., when the LED line lighting fixtures 41 and LED line lighting fixtures 42 are turned on to set the illuminated state), the space in front of the back panel 31 of the rear door 30 in the internal space of the outer frame 10 becomes an illuminated space (i.e., a bright space whose amount of light in that space corresponds to the amount of light from the LED line lighting fixtures 41 and LED line lighting fixtures 42). In this case, the functional panel 22 does not function as a normal mirror (i.e., it does not reflect the scenery or people in the first space S1 on its surface), but transmits the shelf 32, etc., as an image (components or parts exposed in the outer frame, etc.) in the space in the outer frame 10 behind the front door 10, to the outside (the first space S1 side). Therefore, in this case, even when there is an amount of incident light from the first space S1 (typically, even when outside light enters the first space S1 during the day or illumination light from a lighting fixture enters the first space S1 at night), the functional panel 22 does not realize the same reflection function as a normal mirror (a function of inverting an image by reflecting an image), and is not seen as a normal mirror, but allows the shelf 31, etc. behind the functional panel 22 to be seen by a person who enters the first space S1. That is, at this time, the front door 20 functions as normal light-transmitting glass (transparent glass, colored transparent glass, or translucent glass). That is, at this time, the security door structure SS provides an internally illuminated display shelf function by allowing the shelf 31 to be seen by people outside as an internally illuminated display shelf due to the space in front of the back panel 31 inside the outer frame 10.

[0068] <Maintaining invisibility of the front door frame when the internal lighting is on> However, even in this case, as described above, the entire front surface of the frame 21 of the front door 20 is shielded by the functional mirror panel 22, and since the frame 21 of the front door 20 does not transmit any illumination light from the LED line lighting fixtures 41 and LED line lighting fixtures 42 (i.e., since it is made of a non-light-transmitting material), the frame 21 of the front door 20 cannot be seen by people outside.

[0069] <Camouflage of rear door appearance 1 (camouflage of appearance by functioning as an internally illuminated display shelf)> A plurality of shelves 32 (four in the illustrated example) are fixed (by screws, bolts, adhesive, etc.) to the front surface of the back panel 31 of the rear door 30 in a parallel arrangement manner with a predetermined interval or a fixed interval above and below, so as to extend horizontally forward from the back panel 31. The number of shelves 32 and their arrangement positions and intervals (the distance between the shelves 32) can be set appropriately. For example, in the illustrated example, a total of four shelves 32 are arranged between the upper end and the lower end of the back panel 31 at equal intervals (to be precise, at a fixed interval obtained by dividing the distance between the upper end and the lower end of the back panel 31 into about five equal parts), but the number of shelves 31 can be three or five or more, and the distance between any of the shelves 31 can be set to different intervals (not at a fixed interval).

[0070] As described above, the shelf board 32 is fixed to the front surface of the back panel 31 of the rear door 30 so as to extend horizontally forward from the back panel 31, so that the rear door 30 cooperates with the outer frame 10 to present the appearance of a shelf-like piece of furniture inside the outer frame 10 or a shelf-like piece of furniture integrated with the outer frame 10 (typically, a decorative shelf as furniture). Also, as described above, when the LED line lighting fixtures 41 and the LED line lighting fixtures 42 are turned on by an external control device, the security door structure SS provides an internally illuminated decorative shelf function that allows people outside to see the shelf board 31 as an internally illuminated decorative shelf by the space in front of the back panel 31 inside the outer frame 10. Therefore, even when the functional mirror panel 22 of the rear door 30 realizes a light transmission function similar to that of ordinary light-transmitting glass, a person who enters the first space S1 recognizes the shelf board 31 and the like visible through the functional mirror panel 22 of the front door 20 as an internally illuminated decorative shelf. That is, by being recognized as an internally illuminated display shelf, the rear door 30 prevents a person entering the first space S1 from recognizing that the rear door 30 is a door, and realizes an appearance camouflage function that causes the person to mistakenly believe that the shelf 32 of the rear door 30 is an internally illuminated display shelf.

[0071] <Camouflage of rear door appearance 2 (camouflage with hidden hinges)> Also, the rear door 30 realizes the opening and closing function as a door by connecting the back panel 31 to the left panel 13 via the hidden hinge 35 so that it can be opened and closed freely, so the hinge is not visible from the outside, unlike a normal hinge (such as a sliding hinge). Therefore, in addition to the appearance camouflage function of mistaking it for an internally illuminated display shelf as described above, even when the back panel 31 and shelf panel 32 of the rear door 30 are illuminated by the illumination light of the LED line lighting fixtures 41 and 42, a person who enters the first space S1 will not recognize the rear door 30 as a door, but will mistakenly recognize it as an internally illuminated display shelf, and this hidden hinge 35 provides additional appearance camouflage for the rear door 30.

[0072] <Front door lock device (first lock device)> The security door structure SS of the first embodiment uses an electromagnetic locking device of a predetermined configuration, which will be described later, as a locking device (or door lock device) for the front door 20 serving as the first security door. That is, the security door structure SS according to the first embodiment uses an electromagnetic locking device of a predetermined configuration, which will be described later, as a first locking device for the front door 20 serving as the first security door.

[0073] <Conventional electric lock device> Here, a so-called electric lock device (generally called an "electric lock") has been proposed as a lock device, and this electric lock device is a lock device that can automatically open and close a door using a remote control device or a sensor (touch sensor, non-contact sensor) without carrying a key for locking and unlocking the lock. This electric lock device is generally composed of three components: an electric lock main body, an operating member or operating unit, and a control member or control unit. The electric lock main body is attached to a door or a door in the same way as a normal lock, and locks the door or door (for example, by inserting and fitting the deadbolt of the electric lock main body attached to the door side into the strike attached to the corresponding position of the door frame) and unlocks the door or door (for example, by retracting the deadbolt of the electric lock main body attached to the door side from the strike attached to the corresponding position of the door frame). The operating member or operating unit is for locking or unlocking the door by bringing a key (e.g., a card-type key) corresponding to the electric lock body close to the electric lock body or by inputting a predetermined secret number. The control member or control unit is for generating and transmitting a command signal for operating the electric lock body (i.e., locking and unlocking operations) by the operation of the operating member or operating unit.

[0074] Various kinds of electric lock devices have been proposed. Representative electric lock devices include a PIN-type electric lock device, a remote control type electric lock device, a card type electric lock device, a fingerprint authentication type electric lock device, and a touch key type electric lock device. A PIN-type electric lock device is configured such that a control panel for inputting a PIN is installed on the side of the door (for example, in a position near the open end opposite the end of the door that is attached to the door frame), and the door can be unlocked by inputting a PIN (known only to the user) into the control panel. A remote control type electric lock device unlocks the door using a remote control device (substitute for a normal key), and the door can be unlocked by pressing a specific key button provided on the remote control device. The card-type electric lock device unlocks the door using a card key (substitute for a normal key), and an operation panel for the card key is installed on the side of the door (for example, near the open end opposite the end of the door attached to the door frame), and the door can be unlocked by inserting a magnetic card as the card key into the operation panel or holding an IC card as the card key over the operation panel. The fingerprint authentication electric lock device installs an operation panel for fingerprint authentication on the side of the door (for example, near the open end opposite the end of the door attached to the door frame), and when a user touches his / her finger to the operation panel, the fingerprint of the user registered in advance is read, and the user's identity is confirmed, and the door can be unlocked. The touch key electric lock device installs an operation panel with a touch sensor on the side of the door (for example, near the open end opposite the end of the door attached to the door frame), and the door can be unlocked by touching the operation panel with a palm or the like.

[0075] However, these PIN-type electric lock devices, remote control-type electric lock devices, card-type electric lock devices, fingerprint authentication-type electric lock devices, and touch key-type electric lock devices are all structured to lock and unlock the door by causing the deadbolt to protrude and retract (and then causing the deadbolt to enter and engage with the strike on the other side or retract from the strike) using a solenoid or motor built into the case (case-shaped case) of the electric lock main body, so the structure (electrical structure and mechanical structure) for this purpose becomes complicated and somewhat large. Furthermore, in the case of these electric lock devices, the electric lock main body with the complicated and large structure is attached and installed on the door side. Therefore, in the case of these electric lock devices, the electric lock main body is largely exposed at the open end of the door, so that even a person (other than the user) who sees the door can easily recognize that an electric lock device has been installed on the door. In addition, in the case of these electric locking devices, as described above, it is necessary to install the above-mentioned operation panel on the side of the door (for example, in a position near the open end opposite the end of the door that is attached to the door frame). Therefore, in the case of these electric locking devices, since the operation panel is largely exposed on the side of the open end of the door, even a person who sees the door (a person other than the user) can easily recognize that an electric locking device has been installed on the door.

[0076] As a result, these electric locking devices are inappropriate for use as locking devices for the security door structure of the present invention, including the security door structure SS of this embodiment. In the case of the security door structure of the present invention, including the security door structure SS of this embodiment, it is essential that only the manager of the security door structure knows the existence of the security door (for example, that the front door 20 is a security door), and that it is essential that people other than the manager cannot easily recognize the existence of the security door.

[0077] <Electromagnetic locking device for the front door (first security locking device)> Focusing on the problems of the conventional electric locking devices described above, the security door structure SS of this embodiment uses an electromagnetic locking device of a predetermined configuration as a locking device (or door lock device) for the front door 20 serving as the first security door. That is, the security door structure SS according to the first embodiment is characterized in that an electromagnetic locking device of a predetermined configuration, which will be described later, is used as the first locking device for the front door 20 serving as the first security door. This electromagnetic locking device includes an electromagnetic lock main body 50 having the configuration shown in Figs. 2 to 7 (particularly the enlarged view of Fig. 3), the enlarged view of Fig. 11, and Fig. 18, and a control box 80 shown in Figs. 13, 15 to 19.

[0078] <Electromagnetic lock unit of the electromagnetic lock device for the front door> An electromagnetic lock body 50 of an electromagnetic lock device comprises an electromagnetic attraction block body 51 constituting the electromagnetic attraction member of the electromagnetic lock, and a strike plate 52 constituting the electromagnetically attracted member of the electromagnetic lock.

[0079] <Electromagnetic adsorption block for the electromagnetic lock body> The electromagnetic attraction block body 51 of the electromagnetic lock main body 50 has a horizontally elongated (i.e., extending in the left-right direction) rectangular block shape having a predetermined left-right dimension (length dimension), a predetermined height dimension (width dimension), and a predetermined depth dimension (thickness dimension) as a whole. The electromagnetic attraction block body 51 has an electromagnet embedded therein, and exposes the electromagnetic attraction surface of the electromagnet on its front surface. As shown in FIG. 3, the electromagnetic attraction block body 51 is embedded or housed in a storage recess formed at the right end of the front end of the upper plate 11 of the outer frame 10, and is fixed at a predetermined position in the storage recess by fixing its rear surface (rear side surface) to the bottom surface (rear surface) of the storage recess by a predetermined fixing means (screw fastening, bolt fastening, etc.).

[0080] The storage recess of the upper plate 11 is disposed at the front end of the upper plate 11, and at this time, the right end of the storage recess is disposed at the corner position (corner position) where the upper plate 11 and the right plate 14 are perpendicular to each other at the right end of the upper plate 11, and the storage recess is formed in a rectangular parallelepiped recess extending a predetermined dimension along the upper plate 11 from the right end to the left. That is, the storage recess of the upper plate 11 has a horizontally elongated (i.e., extending in the left-right direction) rectangular parallelepiped recess shape having a predetermined left-right dimension (length dimension), a predetermined height dimension (width dimension), and a predetermined depth dimension (thickness dimension). The dimensions of the storage recess of the upper plate 11 are set so that its left-right dimension is the same as the left-right dimension of the electromagnetic adhesion block body 51, and its height dimension is the same as the height dimension of the electromagnetic adhesion block body 51.

[0081] Further, the depth dimension of the accommodating recess of the upper plate 11 is set to be a predetermined dimension larger than the depth dimension (thickness dimension) of the electromagnetic adsorption block body 51. That is, the depth dimension of the accommodating recess of the upper plate 11 is set to be a dimension larger than the depth dimension (thickness dimension) of the electromagnetic adsorption block body 51 by the same dimension as the thickness dimension of the strike plate 52. As a result, with the electromagnetic adsorption block body 51 fixedly disposed in the accommodating recess of the upper frame 11, a gap (i.e., a rectangular parallelepiped recess space) having the same thickness dimension as the predetermined dimension (i.e., the same thickness dimension as the thickness dimension of the strike plate 52) is formed between the front surface of the electromagnetic adsorption block body 51 and the front surface of the upper frame 11 (i.e., the front end of the accommodating recess).

[0082] Therefore, in a state where the electromagnetic attraction block body 51 is accommodated and fixed in the accommodation recess of the upper plate 11, the electromagnetic attraction block body 51 is entirely accommodated in the accommodation recess of the upper plate 11, is not exposed to the outside (for example, the right side is to the front) from the accommodation recess of the upper plate 11, and the front surface (front electromagnetic attraction surface) of the electromagnetic attraction block body 51 is disposed at a position retreated a predetermined distance from the front end of the accommodation recess of the upper plate 11 toward the rear (i.e., a distance obtained by subtracting the depth dimension of the electromagnetic attraction block body 51 from the depth dimension of the accommodation recess of the upper plate 11). In other words, the front surface (front electromagnetic attraction surface) of the electromagnetic attraction block body 51 is disposed at a position retreated a predetermined distance from the front end of the accommodation recess of the upper plate 11 toward the rear (i.e., a distance equal to the thickness dimension of the strike plate 52).

[0083] Furthermore, when the electromagnetic adsorption block body 51 is accommodated and fixed in the accommodating recess of the upper plate 11, the right end position of the electromagnetic adsorption block body 51 coincides with the right end position of the upper plate 11 of the outer frame 10 (i.e., the position of the right end face of the upper plate 11). Therefore, (the inner surface of the upper end portion on the right end face of the upper plate 11) is completely accommodated within the accommodating recess on the inner surface (left side) of the right plate 14 and is not exposed to the outside (for example, the right side to the front) from the accommodating recess of the upper plate 11, and the front surface (front electromagnetic adsorption surface) of the electromagnetic adsorption block body 51 is positioned at a position retreated a predetermined distance toward the front end of the accommodating recess of the upper plate 11 (i.e., the distance obtained by subtracting the depth dimension of the electromagnetic adsorption block body 51 from the depth dimension of the accommodating recess of the upper plate 11). That is, the front surface (front electromagnetic attraction surface) of the electromagnetic adsorption block body 51 is positioned at a position retreated a predetermined distance (i.e., the same dimension as the thickness dimension of the strike plate 52) from the front end of the accommodating recess of the upper plate 11 toward the rear.

[0084] <Strike plate of electromagnetic lock body> The strike plate 51 of the electromagnetic lock main body 50 has a horizontally long (i.e., extending in the left-right direction) rectangular flat plate shape having a predetermined left-right dimension (length dimension), a predetermined height dimension (width dimension), and a predetermined depth dimension (thickness dimension) as a whole. The strike plate 51 is disposed at a predetermined position on the right end side of the upper frame portion (a band-shaped portion extending horizontally in the left-right direction at the upper end side of the frame 21) of the front door 20, and is fixed at a predetermined position on the upper frame portion of the frame 21 by fixing its front surface (front side surface) to the rear surface (rear side surface) of the upper frame portion of the frame 21 by a predetermined fixing means (screw fastening, bolt fastening, etc.). The dimensions of the strike plate 52 are set so that its left-right dimension is the same as the left-right dimension of the electromagnetic adsorption portion of the electromagnetic adsorption block body 51, and its height dimension is the same as the height dimension of the electromagnetic adsorption portion of the electromagnetic adsorption block body 51. In addition, the depth dimension (thickness dimension) of the strike plate 52 is set to be the same as the thickness dimension (i.e., depth dimension) of the recess space between the front surface of the electromagnetic adsorption block body 51 (formed when the electromagnetic adsorption block body 51 is fixedly positioned in the accommodating recess of the upper frame 11) and the front surface of the upper frame 11 (i.e., the front end of the accommodating recess).

[0085] Also, the strike plate 51 is fixedly disposed at a predetermined position on the right end side portion of the upper frame portion of the frame 21 of the front door 20 at a position that aligns with the electromagnetic adsorption portion of the electromagnetic adsorption block body 51 in the upper plate 11 of the outer frame 10. That is, as shown in Figures 2 to 4, in the security door structure SS, when the front door 20 is in a completely closed state (closed position) relative to the outer frame 10, the rear surface (i.e., the surface or exposed surface facing the electromagnetic adsorption plate 51) of the strike plate 51 of the upper frame portion of the frame 21 is configured to completely align with and come into close contact with the electromagnetic adsorption portion of the electromagnetic adsorption block body 51 in the accommodation recess of the upper plate 11 of the outer frame 10. In addition, at this time, the strike plate 51 of the upper frame portion of the frame 21 is completely accommodated within a gap (rectangular recess space) having a thickness dimension identical to that of the strike plate 52, which is formed within the accommodating recess of the upper plate 11 of the outer frame 10 between the front surface of the electromagnetic adsorption block body 51 and the front surface of the upper frame 11 (i.e., the front end of the accommodating recess), and is adapted to be completely aligned and in close contact with the electromagnetic adsorption portion of the electromagnetic adsorption block body 51 within the accommodating recess of the upper plate 11.

[0086] <Configuration of the electromagnetic lock body> As described above, the electromagnetic lock body 50 of the electromagnetic lock device is configured without including any electrical or mechanical parts (solenoid, motor, deadbolt, strike with a recess that fits with the deadbolt, troyoke, etc.) for locking and unlocking like conventional electric locks.

[0087] <The function of concealing the electromagnetic lock body by the recessed storage area of ​​the front door frame and outer frame> As described above, in the security door structure SS, when the front door 20 is in a completely closed state (closed position) relative to the outer frame 10, the electromagnetic attraction block body 51 is completely accommodated in the accommodation recess of the upper plate 11 of the outer frame 10 and is not exposed to the outside from the accommodation recess of the upper plate 11. Furthermore, when the front door 20 is in the closed state, the electromagnetic attraction block body 51 in the accommodation recess of the upper plate 11 of the outer frame 10 is completely hidden or concealed from the outside of the security door structure SS (i.e., from a person on the first space S1 side as viewed from the security door structure SS) by the upper frame portion of the frame 21 of the front door 20 that is in close contact with the front end face of the upper plate 11 in front of the outer frame 10. In addition, the strike plate 51 of the upper frame portion of the frame 21 is completely accommodated in a gap (rectangular parallelepiped recessed space) having the same thickness dimension as that of the strike plate 52, which is formed between the front surface of the electromagnetic adsorption block body 51 and the front surface of the upper frame 11 in the accommodating recess of the upper plate 11 of the outer frame 10, and is in close contact with and completely aligned with the electromagnetic adsorption portion of the electromagnetic adsorption block body 51 in the accommodating recess of the upper plate 11. Therefore, it is completely impossible for a person who enters the interior space (i.e., the first space S1) of the room in which the security door structure SS is arranged to see the electromagnetic lock main body 50 through the front door 20, and the frame 21 of the front door 20 and the accommodating recess of the outer frame 10 function to conceal the electromagnetic lock main body 50. The above-mentioned electric lock concealment function is also exerted when the inside of the outer frame 10 is illuminated and brightened by the LED line lighting fixtures 41 and 42, which are interior lighting fixtures, and the shelves 32 etc. inside the outer frame 10 are visible to a person in the indoor space S1 through the functional mirror panel 22 of the front door 20 (more precisely, through the light-transmitting part consisting of the outer peripheral edge of the functional mirror panel 22, i.e., the main part of the center excluding the part where the frame 21 is present).

[0088] <Electromagnetic adhesion operation (locking operation) and electromagnetic adhesion release operation (unlocking operation) of the electromagnetic lock body> The electromagnetic adsorption operation (locking operation) of the strike plate 52 by the electromagnetic adsorption block body 51 of the electromagnetic lock main body 50, and the electromagnetic adsorption release operation (unlocking operation) of the strike plate 52 by the electromagnetic adsorption block body 51 of the electromagnetic lock main body 50 are realized by the following configuration.

[0089] <Non-contact sensor (non-contact detection unit) for electric lock devices> As shown in Figs. 13 to 18 (particularly, the side view in Fig. 13 and the front views in Figs. 15 to 18), the electromagnetic lock device includes a control box 80 for commanding and executing the unlocking operation of the electromagnetic lock main body 50. In detail, the control box 80 as a control device includes a case 81 having a predetermined housing shape and a non-contact detection unit 82 consisting of a microwave sensor as a non-contact sensor arranged inside the case 81. The case 81 can be configured as a rectangular box-shaped storage case having a predetermined height dimension, a predetermined width dimension, and a predetermined depth dimension, for example. In addition, the non-contact detection unit 82 is configured to incorporate various electrical components (hereinafter referred to as a "control unit") such as a power circuit and a control board (not shown) in the internal space of the case 81, and the control unit is configured to realize various control processes for the electromagnetic lock device. That is, the control unit of the control box 80 is electrically connected to the non-contact detection unit 82 inside the case 81, and is also electrically connected to the electromagnetic adsorption portion of the electromagnetic adsorption block body 51 via a signal cable as a wired communication medium that is pulled out to the outside of the case 81.

[0090] The control unit of the control box 80 supplies a predetermined power to the non-contact detection section 82 to realize the detection operation of the non-contact detection section 82, receives a detection signal from the non-contact detection section 82 to realize processing according to the detection operation of the non-contact detection section 82 (i.e., transmits an electrical signal for turning off the electromagnetic adsorption section of the electromagnetic adsorption block body 51 to the electromagnetic adsorption block body 51 to release the electromagnetic adsorption drive state of the electromagnetic adsorption section of the electromagnetic adsorption block body 51), and (when there is no detection signal input from the non-contact detection section 82, always) turns on the electromagnetic adsorption section of the electromagnetic adsorption block body 51 (i.e., drives the electromagnetic adsorption section of the electromagnetic adsorption block body 51 by electromagnetic adsorption to generate an electromagnetic adsorption force). (i.e., releases the electromagnetic adsorption drive state of the electromagnetic adsorption part of the electromagnetic adsorption block body 51 and erases the electromagnetic adsorption force of the electromagnetic adsorption part only for a predetermined drive time when a detection signal is input from the non-contact detection unit 82) or (when the predetermined drive time has elapsed after receiving the input of the detection signal from the non-contact detection unit 82) turns on the electromagnetic adsorption part of the electromagnetic adsorption block body 51 again (i.e., drives the electromagnetic adsorption part of the electromagnetic adsorption block body 51 again to generate electromagnetic adsorption force until the next input of the detection signal from the non-contact detection unit 82).

[0091] The control unit of the control box 80 is electrically connected to an external power source (such as an AC power source) via a power line (electric cable) or the like, or to an internal power source provided inside, to realize the various control operations described above. On the other hand, when the power supply from the external power source (such as an AC power source) is stopped due to a power outage or the like, the control unit of the control box 80 stops sending the electromagnetic attraction drive signal to the electromagnetic attraction portion of the electromagnetic attraction block body 51 (i.e., the supply of power for electromagnetic attraction), the generation of electromagnetic attraction force by the electromagnetic attraction portion of the electromagnetic attraction block body 51 stops, and the electromagnetic attraction of the strike plate 52 by the electromagnetic attraction portion of the electromagnetic attraction block body 51 is released. Alternatively, the control unit of the control box 80 can be configured to continue transmitting the electromagnetic attraction drive signal to the electromagnetic attraction portion of the electromagnetic attraction block body 51 (i.e., supplying power for electromagnetic attraction) by an emergency power supply device such as an uninterruptible power supply (UPS) even when the power supply from an external power source (such as an AC power source) is stopped due to a power outage or the like, to continue generating electromagnetic attraction force by the electromagnetic attraction portion of the electromagnetic attraction block body 51, and to continue electromagnetic attraction of the strike plate 52 by the electromagnetic attraction portion of the electromagnetic attraction block body 51. In this case, the control unit of the control box 80 can also realize control to turn off the electromagnetic attraction portion of the electromagnetic attraction block body 51 for a predetermined drive time when a detection signal is input from the non-contact detection unit 82 as described above (i.e., control to cancel the electromagnetic attraction drive state of the electromagnetic attraction portion of the electromagnetic attraction block body 51 and erase the electromagnetic attraction force of the electromagnetic attraction portion).

[0092] As described above, when the non-contact detection unit 82 of the control box 80 does not detect an object such as a person's palm that has entered a specified detection region (detection area) by reflecting microwaves, the control unit supplies a specified amount of power to the electromagnetic adsorption block body 51 of the electromagnetic lock main body 50, thereby achieving an operation of generating an electromagnetic adsorption force in the electromagnetic adsorption portion of the electromagnetic adsorption block body 51 (electromagnetic adsorption operation).

[0093] On the other hand, when the non-contact detection unit 82 of the control box 80 detects an object such as a human hand that has entered a specified detection region (detection area) by reflecting microwaves and generates a detection signal, the detection signal of the non-contact detection unit 82 is input to the electromagnetic adsorption operation control unit, and the control unit stops the supply of a specified amount of power to the electromagnetic adsorption block body 51 of the electromagnetic lock main body 50, thereby realizing an operation of stopping the generation of electromagnetic adsorption force by the electromagnetic adsorption part of the electromagnetic adsorption block body 51 (electromagnetic adsorption stopping operation or electromagnetic adsorption releasing operation).

[0094] <Front door lock / unlock control by control box> By controlling the on and off operation of the electromagnetic adsorption operation of the electromagnetic adsorption block body 51 by this control box 80 with a control unit in response to the object detection operation by the non-contact sensor 82, it is possible to control the locking operation and locked state, as well as the unlocking operation and unlocked state, of the front door 20 (to which the strike plate 52 is fixed) relative to the outer frame 10 (to which the electromagnetic adsorption block body 51 is fixed).

[0095] <Concealment of the front door's function by locking the control box> That is, in the security state maintenance mode, which is the normal use mode of the security door structure SS, in the indoor space in which the security door structure SS is installed, among people who enter the first space S1, people other than the manager (who knows the existence of the security door structure SS) cannot recognize that the front door 20 is a security door (first security door), so that the electromagnetic adsorption block body 51 of the electromagnetic lock device generates and maintains the electromagnetic adsorption force of the electromagnetic adsorption part by the power supply from the control box 80, and maintains a state in which the strike plate 52, which faces or is in close contact with the front door 20, is electromagnetically adsorbed by a predetermined electromagnetic adsorption force (for example, an electromagnetic adsorption force of 90 kgf to 200 kgf) of the electromagnetic adsorption part. Therefore, even if a pulling force is applied to the front door 20 unintentionally in a direction to open the front door 20, the front door 20 resists the pulling force and maintains a close state (i.e., a closed state) to the outer frame 10 by the electromagnetic adsorption force, and the front door 20 will not open unintentionally. In other words, by maintaining the locked state of the electromagnetic locking device as described above using the control box 80, the door function of the front door 20 can be concealed from people other than the administrator (i.e., the fact that the front door 20 is a door can be hidden).

[0096] <Realizing the front door function by controlling the unlocking of the control box> On the other hand, in the security state stop mode, which is the emergency use mode of the security door structure SS, among the people who enter the first space S1 in the indoor space where the security door structure SS is installed, only the manager (who knows the existence of the security door structure SS) recognizes that the front door 20 is a security door (first security door). Therefore, when the manager wants to enter the security room (second space S2) behind the security door structure SS, he can unlock the front door 20 by placing his palm over the space in front of the control box 80 (in the illustrated example, the space in front of the first storage section 120 on the left side of the display 112 in the internal space of the display structure SS). That is, at this time, the non-contact detection section 82 of the electromagnetic lock device detects the palm of the manager and transmits a detection signal to the control unit, and the control unit stops the supply of power (which had been supplied until then) to the electromagnetic adsorption block body 51, so that the electromagnetic adsorption force of the electromagnetic adsorption section of the electromagnetic adsorption block body 51 disappears. As a result, the strike plate 52, which faces or is in close contact with the electromagnetic adsorption portion, can detach from the electromagnetic adsorption portion without being subjected to the electromagnetic adsorption force from the electromagnetic adsorption portion, and the manager can open the front door 20 by swinging it forward.

[0097] <Front door opening operation assistance mechanism (push-out pin device)> Furthermore, as shown in the enlarged view at the top of FIG. 3, an ejector pin device 60 is disposed in the upper plate 11 of the outer frame 10 at a predetermined position (i.e., a predetermined position a predetermined distance to the left of the electromagnetic attraction block body 51) on the left side of the electromagnetic attraction block body 51 (for example, a distance equal to the length dimension of the electromagnetic attraction block body 51) in the widthwise center position. The ejector pin device 60 has an ejector pin 61 and a pressure spring 62 as an example of a biasing member that applies a pressing force to the ejector pin 61 in its length direction (precisely forward). The pressure spring and the ejector pin 61 are housed and arranged in this order in a bottomed recess with a circular cross section and a predetermined depth, which is provided in the upper plate 11 of the outer frame 10 at the predetermined position a predetermined distance to the left of the storage recess. When the front door 20 is closed against the outer frame 10 in the door closed state, the strike plate 52 on the inner surface of the upper frame portion of the frame 21 of the front door 20 is in close contact with the adsorption surface of the electromagnetic adsorption portion of the electromagnetic adsorption block body 52 in the storage recess of the upper plate 11 of the outer frame 10, and the tip of the ejection pin 61 of the ejection pin device 60 abuts against the inner surface at the corresponding position of the upper frame portion of the frame 21 of the front door 20. At this time, as described above, when the electromagnetic adsorption force of the electromagnetic adsorption block body 51 on the strike plate 52 is acting (i.e., when the electromagnetic lock device is in the locked state), the electromagnetic adsorption force of the electromagnetic adsorption block body 51 on the strike plate 52 causes the inner surface at the corresponding position of the upper frame portion of the frame 21 of the front door 20 to press the ejection pin 61 (more precisely, the tip of the ejection pin 61) against the pressing force of the compression spring, causing the ejection pin 61 to be completely immersed in the accommodating recess of the ejection pin device 60 in the upper plate 11 of the outer frame 10.

[0098] On the other hand, as described above, when the non-contact detection unit 82 detects the manager's palm and the electromagnetic attraction of the strike plate 52 by the electromagnetic attraction block body 51 is released, as shown in the enlarged view at the bottom of FIG. 3, the electromagnetic attraction force of the electromagnetic attraction block body 51 to the strike plate 52 disappears (i.e., the electromagnetic lock device is in an unlocked state), and the push-out pin 61 (more precisely, the tip of the push-out pin 61) presses the inner surface of the corresponding position of the upper frame part of the frame 21 of the front door 20 due to the pressing force of the pressing spring, and the push-out pin 61 protrudes a predetermined distance from the accommodating recess of the push-out pin device 60 in the upper plate 11 of the outer frame 10. Therefore, the push-out pin 61 protruding a predetermined distance from the accommodating recess of the push-out pin device 60 in the upper plate 11 of the outer frame 10 presses the inner surface of the corresponding position of the upper frame part of the frame 21 of the front door 20, and the front door 20 opens at least by an amount corresponding to the amount of protrusion of the push-out pin 61. Therefore, an administrator can hook his / her finger or the like on the right end of the front door 20, which has been opened an amount corresponding to the protrusion amount of the push-out pin 61, and pull it forward (i.e., in the direction of opening the front door 20 further), thereby opening the front door 20 to the desired amount, as shown by the virtual line in Figure 4, and also to bring it into a fully open state.

[0099] <Detection range or detection limit of non-contact sensor (existence of normally non-detectable parts)> The non-contact detection unit 82 is composed of a microwave sensor (or a microwave sensor switch) as a non-contact sensor, and has a predetermined detection region (sometimes called a "detection range" or a "detection area" or a "detection region" or a "detection range" or a "detection area") DA as shown by a virtual line (a dashed line) in the side view of Fig. 13 and the front view of Fig. 16. That is, the non-contact detection unit 82 of the control box 80 constantly irradiates microwaves forward, detects an object (e.g., a person's palm, etc.) entering the space in front, generates a detection signal, and transmits the detection signal to the control unit, but at this time, the detection or detection of an object by the microwaves irradiated by the non-contact detection unit 82 is effective only within a predetermined spatial range (i.e., within a predetermined spatial region). The detection area DA of the non-contact detection unit 82 has a predetermined height dimension DA1 extending in the up-down direction of the space in front of the non-contact detection unit 82 as shown in Fig. 13 and Fig. 16, and has a predetermined width dimension DA2 extending in the left-right direction of the space in front of the non-contact detection unit 82 as shown in Fig. 16. The detection area DA of the non-contact detection unit 82 has a predetermined length dimension extending in the front-rear direction of the space in front of the non-contact detection unit 82, and the length dimension of the detection area DA in the front-rear direction is set so that a predetermined distance (for example, about 10 cm) from the front surface (microwave radiation surface) of the non-contact detection unit 82 becomes a non-detection area, and a predetermined distance (for example, about 50 to 60 cm) further forward in the front-rear direction. The detection area DA of the non-contact detection unit 82 can be set to a predetermined range by the control unit.

[0100] In other words, the detection area DA of the non-contact sensor 82 is limited to a predetermined spatial range or a predetermined spatial region, and a predetermined detection limit exists. In particular, the detection area DA of the non-contact sensor is limited to the spatial range of the height dimension DA1 and the width dimension DA2 in the space in front of the non-contact sensor 82, and the range outside the spatial range of the height dimension DA1 and the width dimension DA2 is a region that cannot be detected by the non-contact sensor 82 (hereinafter referred to as the "non-detection area"). For example, even if an object such as a human palm enters or approaches in a spatial range outside the detection area DA of the non-contact detection unit 82 (i.e., a space outside the spatial range of the height dimension DA1 and the width dimension DA2), the non-contact sensor 82 does not detect the object, and no detection signal is input from the non-contact sensor 82 to the control unit of the control box 80. As a result, the electromagnetic adsorption operation of the electromagnetic adsorption block body 51 is not stopped by the control unit of the control box 80.

[0101] <Freely change the non-contact sensor detection area within the normally dark space (making the front door unlocking operation more difficult)> The control box 80, in which the detection area of ​​the non-contact sensor 82 is limited to a certain spatial area as described above, is installed in a closed spatial area provided outside the outer frame 10 within the internal space of the wall structure WS of this embodiment (for example, any one of the internal space of the display structure DS adjacent to the security door structure SS, the internal space of the wardrobe structure RS adjacent to the display structure DS, or the internal space of the cabinet structure CS adjacent to the wardrobe structure RS), and is positioned and installed in a spatial area at a desired position selected by an administrator in a spatial area that always maintains its function as a dark area (hereinafter referred to as a ``normally dark spatial area'') even when illumination by a lighting fixture or image projection by a display is performed in the internal space.

[0102] For example, the control box 80 can be disposed on the shelf 122 of the first storage section 120 in the internal space of the display structure DS and at a position to the left of the shelf 122, as shown in FIG. 22. Alternatively, the control box 80 can be disposed on the shelf 122 of the first storage section 120 in the internal space of the display structure DS and at a position to the right of the shelf 122, as shown in FIG. 23. Alternatively, the control box 80 can be disposed on another shelf provided below the shelf 122 of the first storage section 120 in the internal space of the display structure DS and at a position to the left of the shelf, as shown in FIG. 24. Alternatively, the control box 80 can be disposed on another shelf provided below the shelf 122 of the first storage section 120 in the internal space of the display structure DS and at a position to the right of the shelf, as shown in FIG. 25. Alternatively, the control box 80 can be disposed on the bottom plate of the first storage section 120 in the internal space of the display structure DS and at a position to the left of the bottom plate, as shown in Fig. 26. Alternatively, the control box 80 can be disposed on the bottom plate of the first storage section 120 in the internal space of the display structure DS and at a position to the right of the bottom plate, as shown in Fig. 27.

[0103] Alternatively, the control box 80 can be arranged on the bottom plate of the second storage section 130 in the internal space of the display structure DS and at a position to the left of the bottom plate, as shown in Fig. 28. Alternatively, the control box 80 can be arranged on one of the shelves (e.g., two shelves) provided in the second storage section 130 in the internal space of the display structure DS and at a position to the right or left of the shelf. Alternatively, the control box 80 can be arranged on a shelf provided to extend in the left-right direction above the display 112 in the space above the display 112 in the internal space of the display structure DS and at an arbitrary position of the shelf (e.g., a position to the left) as shown in Fig. 29.

[0104] Here, in the internal space of each of the above structures, the portion of the spatial region where the control box 80 is placed is a constantly dark spatial region that maintains the function as a dark space even when the internal space is illuminated by a lighting fixture, as described above. Here, the constantly dark spatial region is located outside the illumination range of the illumination light in the internal space of each structure, and can be configured by any section region as long as it is a spatial region that the illumination light does not reach. Typically, in the internal space of the display structure D2, the spatial region around the display 112 can be used as the constantly dark spatial region. That is, in the internal space of the display structure D2, when the display 112 is in an off state and no image (i.e., image light) is emitted from the screen or screen surface of the display 112, the entire internal space of the display structure D2 is naturally in a dark space state (i.e., a state in which there is absolutely no light in the internal space of the display structure DS). However, even when the display 112 is turned on and in an on state and an image (i.e., image light) is emitted from the screen or screen surface of the display 112, the emitted light from the screen of the display 112 is only emitted toward the outside (i.e., the first space S1) from the functional mirror panel 111, which is located in a position immediately in front of or approximately close to it, and does not enter at all into the internal space of the display structure D2, particularly into the spatial region on the outer periphery of the display 112. That is, in the internal space of the display structure D2, particularly the spatial area around the periphery of the display 112, all of them always maintain the state of the dark space (i.e., a state in which absolutely no light is present in the internal space of the display structure DS), and therefore can be used as the constantly dark space area.

[0105] Therefore, if the control box 80, whose detection area of ​​the non-contact sensor 82 is limited to a certain spatial area, is placed at any position in the spatial area around the periphery of the display 112 in the internal space of the display structure DS (i.e., at any desired position in the entire spatial area), the control box 80 will be placed in the always dark spatial area, and even when the display 112 is in the on state in the display structure DS (not only when the display is in the off state), the control box 80 will always be placed in the always dark spatial area, which is a spatial area that always maintains its function as a dark area.By placing and installing the control box 80 at a desired position selected from such a large always dark spatial area by the administrator, persons other than the administrator (even if they obtain information that the front door 20 is a security door and know that in order to open the front door 20, they only need to hold their hand or the like within the detection range in front of the non-contact sensor) will have to search for the location of the non-contact sensor (i.e., where the control box 80 is placed) from a vast area.

[0106] That is, when the control box 80 is disposed at a position in the constantly dark space region of the display structure DS, in order for a person other than the administrator to determine at what position in the constantly dark space region the control box 80 is disposed in the display structure DS (even if the person knows that a non-contact sensor is disposed at a position in the internal space of the display structure DS), it is necessary to accurately identify the detection region DA of the non-contact detection unit 82 in a vast area in front of the display structure DS. However, since this detection region DA is a narrow area as described above (i.e. In order to accurately identify the detection area DA of the non-contact detection unit 82, for example, it is necessary to divide and grasp the vast area in front of the display structure DS into small areas each having an area equivalent to the detection area DA of the non-contact detection unit 82 (i.e., a narrow area whose outer edge of the detection range is defined by the specified small height dimension DA1 and the specified small width dimension DA2), and then to hold a palm over each of the small areas thus grasped to test whether the non-contact sensor reacts. However, with such a method, the number of small areas obtained by dividing the vast area in front of the display structure DS becomes enormous, and in reality, it is extremely difficult for anyone other than the administrator to accurately identify the position where the non-contact detection unit 82 as a non-contact sensor is located (more precisely, the detection area DA of the non-contact detection unit 82) in the vast area in front of the display structure DS.In this way, by allowing the administrator to freely change and select the location of the non-contact detection unit 82 as a non-contact sensor (i.e., the location of the detection area DA) within the vast constantly dark space area, it is made extremely difficult for anyone other than the administrator (who does not know the location of the non-contact detection unit 82, i.e., the location of the detection area DA) to unlock the front door 20.

[0107] <Secret positioning function of non-contact sensor detection area based on rear door shelf position> Furthermore, in the security door structure SS of this embodiment, any one of the multiple shelf boards 32 of the rear door 30 can be used as a marker (indication) for identifying the height position (vertical position) of the control box 80 (for example, housed and arranged in the first housing section 120 of the display structure DS). That is, in the security door structure SS of this embodiment, any one of the multiple shelf boards 32 of the rear door 30 functions as a position confirmation shelf board 32 (PS) for identifying the height position (vertical position) of the control box 80 (for example, housed and arranged in the first housing section 120 of the display structure DS). For example, as shown in Figures 15 to 19, when the control box 80 is stored and placed on top of the shelf 122 of the first storage section 120 of the display structure DS (for example, in a position to the left of the shelf 122), the second shelf 32 from the top among the shelves 32 of the rear door 30 functions as a position confirmation shelf 32 (PS) for the marker (landmark), and the administrator can easily identify that the control box 80 is placed in a position immediately to the right of the position confirmation shelf 32 (PS) for the marker (landmark) in the internal space of the display structure DS. Therefore, even in the case where there is a specific narrow detection area DA as described above and detection requires placing one's palm precisely within the detection area DA in front of the non-contact detection unit 82, the administrator can easily identify the position of the control box 80 (i.e., the position of the non-contact detection unit 82 and the range of its detection area DA) by using the position confirmation shelf 32 (PS) for the marker (landmark), and can easily, quickly and accurately perform the unlocking operation of the front door 20.

[0108] The position confirmation shelf 32 (PS) for the marker (indicator) is not limited to the second shelf 32 from the top, but can be any shelf 32 at a height position corresponding to the height position at which the control box 80 is disposed in the internal space of the display structure DS. For example, when the control box 80 is disposed on the top plate of the first storage section 120 of the display structure DS, the topmost shelf 32 of the rear door 30 can be used as the position confirmation shelf 32 (PS) for the marker (indicator).

[0109] Moreover, as described above, when the LED line lighting device is turned on, the rear door 30 is visually recognized and recognized from the outside as an internally illuminated display shelf, and ornamental items such as antiques such as vases and photo stands are usually placed on the shelves 32. Therefore, even if the manager forgets which shelf 32 from the top is the shelf 32 (PS) for position confirmation for markers (markers), he or she can easily remember which shelf 32 is the shelf 32 (PS) for position confirmation for markers (markers) by memorizing the type of item to be placed on the shelf 32 (PS) for position confirmation for markers (markers). Alternatively, the manager can easily recognize that the shelf 32 on which such a specific item is placed is the shelf that specifies the height position of the control box 80, and can quickly, easily, and accurately unlock the front door 20 by visually checking the item and placing his or her palm over the spatial area in front of the display structure DS at a height position corresponding to the height position of the item. In other words, in the security door structure SS of this embodiment, not only the shelf 32 of the rear door 30 itself, but also the items placed and displayed on the shelf 32 can be used as markers (landmarks) for determining the height position of the control box 80.

[0110] <Rear door lock device (second lock device)> The security door structure SS of embodiment 1 uses a mechanical locking device 70 of a predetermined configuration as a locking device (or door lock device) for the rear door 30 serving as the second security door. That is, the security door structure SS according to embodiment 1 is characterized in that it uses a mechanical locking device 70 of a predetermined configuration as a second locking device for the rear door 30 serving as the second security door. This mechanical locking device 70 uses a mechanical locking device having the configuration shown in Figures 2 to 7 (particularly the enlarged view of Figure 6), the enlarged view of Figure 11, Figures 12, 13, the enlarged view of Figure 18, and the enlarged view of Figure 19. That is, this mechanical lock device 70 comprises a cylinder lock of the type that is locked and unlocked by a rod-shaped key as a lock (i.e., a cylinder lock consisting of a lock case (lock body) 71, a cylinder portion (cylinder) 72, and a deadbolt 73; hereinafter, this may be referred to as a "rod-key type cylinder lock"), a rod-shaped key (not shown) as a key, and a strike (receiving seat or receiving portion) 75. Although not shown, the rod-shaped key is made up of a gripping portion (for example, a roughly elliptical plate-shaped gripping portion) for holding with the fingers, and a cylindrical key portion that protrudes a predetermined length from the gripping portion, and a predetermined key pattern for locking and unlocking is engraved on the outer peripheral surface of the key portion.

[0111] This mechanical locking device 70 is an analog locking device for the rear door 30 serving as a second security door. In the security door structure SS of embodiment 1, a pair of upper and lower mechanical locking devices 70 are fixedly provided at positions near the upper and lower ends of the back surface of the back panel 31 of the rear door 30, respectively.

[0112] The lock case 71 is a housing-like member incorporating the lock structure (lock components) of a rod-shaped key-type cylinder lock, and is shaped like a box having a rectangular or square planar shape. In the case of the lower mechanical lock device 70, the lock case 71 is fixed and disposed at a predetermined position above the upper surface of the lower plate 12 of the outer frame 10 at the lower end of the back plate 31 of the rear door 30 by means of screws or bolts. In detail, the lock case 71 is attached to a predetermined position at the lower end of the rear surface (back) of the back plate 31 so that its lower end is flush with the upper surface of the lower plate 12 (to be precise, so that the lower end of the lock case 71 is approximately flush with the upper surface of the lower plate 12 with a slight gap that does not interfere with the upper surface of the lower plate 12). In addition, the lock case 71 is attached to a predetermined position at the lower end of the back surface (rear surface) of the back panel 31 so that its right end is flush with the inner surface of the right panel 14 (to be precise, so that the right end of the lock case 71 is approximately flush with the inner surface of the right panel 14, with a small gap so as not to interfere with the inner surface of the right panel 14).

[0113] On the other hand, in the case of the upper mechanical lock device 70, the lock case 71 is fixed by screws or bolts or the like at the upper end of the back plate 31 of the rear door 30 at a predetermined position below the lower surface of the upper plate 11 of the outer frame 10. In detail, the lock case 71 is attached to a predetermined position at the upper end of the back surface (rear surface) of the back plate 31 so that its upper end is flush with the lower surface of the upper plate 11 (to be precise, so that the upper end of the lock case 71 is approximately flush with the lower surface of the upper plate 11 with a slight gap so as not to interfere with the lower surface of the upper plate 11), or so that its upper end is attached a certain distance from the lower surface of the upper plate 11. In addition, the lock case 71 is attached to a predetermined position on the upper end of the back surface (rear surface) of the back panel 31 so that its right end is flush with the inner surface of the right panel 14 (to be precise, so that the right end of the lock case 71 is approximately flush with the inner surface of the right panel 14, with a small gap so as not to interfere with the inner surface of the right panel 14).

[0114] The cylinder portion 72 is a cylindrical member that is provided integrally with the lock case 71 so as to protrude forward from the center of the front surface thereof, and has a keyhole formed therethrough in the center for inserting a rod-shaped key. The cylinder portion 72 is provided embedded inside the back plate 31 from the back surface of the lock case 71 (the back surface of the lock case 71). In addition, in the back plate 31, at a position that matches the central keyhole of the cylinder portion 72, a key insertion hole 74 for inserting a circular rod-shaped key having a small diameter (e.g., 8 mm) that is slightly larger than the outer diameter of the rod-shaped key (e.g., an outer diameter of 5 to 6 mm) is formed so as to be coaxial with the keyhole of the cylinder portion 72.

[0115] In the case of the lower mechanical lock device 70, as shown in the enlarged view in Figure 18, only the circular opening at its front end of the key insertion hole 74 is exposed at the corresponding position on the front surface of the back panel 31 (the position on the right end side of the lower end portion of the back panel 31).

[0116] In the case of the upper mechanical lock device 70, only the circular opening at the front end of the key insertion hole 74 is exposed at a corresponding position on the front surface of the back plate 31 (the position on the right side of the upper end portion of the back plate 31).

[0117] By inserting a rod-shaped key into the keyhole of the cylinder portion 72 and rotating it in a predetermined direction (typically, clockwise), the rod-shaped key activates a locking mechanism in the cylinder portion 72 and lock case 71, and a deadbolt 73 protrudes from the right side surface (right end surface) of the lock case 71. By inserting a rod-shaped key into the keyhole of the cylinder portion 72 and rotating it in the predetermined direction (typically, counterclockwise), the rod-shaped key activates an unlocking mechanism in the cylinder portion 72 and lock case 71, and the deadbolt 73 protruding from the right side surface (right end surface) of the lock case 71 retracts into the interior of the lock case 71.

[0118] In the case of the lower mechanical lock device 70, the strike 75 is embedded and fixed in a recess formed on the inner surface of the lower end of the right plate 14 in a portion or area facing the right side of the lock case 71.

[0119] In the case of the upper mechanical lock device 70, the strike 75 is embedded and fixed in a recess formed on the inner surface of the upper end portion of the right plate 14 in a portion or area facing the right side surface of the lock case 71.

[0120] Then, as described above, by inserting a rod-shaped key into the cylinder portion 72 to perform the locking operation, the deadbolt 73 protrudes from the right side surface of the lock case 71 and engages with the strike 75 in the recess of the right plate 14, as shown in the enlarged views of Figs. 18 and 19, thereby locking the rear door 30 to the outer frame 10. On the other hand, as described above, by inserting a rod-shaped key into the cylinder portion 72 to perform the unlocking operation, the deadbolt 73 retreats from the strike 75 of the right plate 14 and retracts into the lock case 71, thereby unlocking the rear door 30 to the outer frame 10. In this unlocked state, as shown by the imaginary line in Fig. 5, by pushing any part on the front side of the rear door 30 (for example, the front end of the shelf plate 32) backward, the rear door 30 can be opened from the outer frame 10, and the manager can enter the second space S2 (security room) behind the rear door 30. In addition, in this unlocked state, the rear door 30 can be closed relative to the outer frame 10 by pushing a rear portion of the rear door 30 (for example, the back panel 31) forward as indicated by a solid line in FIG.

[0121] <Invisibility of the exposed part of the mechanical locking device on the front of the back panel> As described above, in the case of the lower mechanical locking device 70, as shown in the enlarged view in Fig. 18, only the circular opening at the front end of the key insertion hole 74 is exposed at a corresponding position on the front surface of the back plate 31 (the position on the right end side of the lower end of the back plate 31). Also, in the case of the upper mechanical locking device 70, only the circular opening at the front end of the key insertion hole 74 is exposed at a corresponding position on the front surface of the back plate 31 (the position on the right end side of the upper end of the back plate 31). Therefore, the above-mentioned circular opening exposed with a very small diameter on the front surface of the back plate of the rear door 30 is itself very difficult to visually recognize.

[0122] As described above, in the security door structure SS of Embodiment 1, as shown in FIG. 14, when the LED line lighting fixtures 41 and 42 are turned on, in the internal space of the outer frame 10, the space in front of the back plate 31 of the rear door 30 is illuminated by the illumination light from the LED line lighting fixtures 41 and 42. As a result, in the internal space of the outer frame 10, the shelf 32 protruding forward from the back plate 31 of the rear door 30 is illuminated in a manner corresponding to the light amount and illumination range of the illumination light. Also, in this illumination state, light of a predetermined light amount from the LED line lighting fixtures 41 and 42 is radiated forward from the rear side of the functional mirror plate 22 of the front door 20 and enters the functional mirror plate 20 as light of the predetermined light amount, and the functional mirror plate 20 transmits the light of the predetermined light amount.

[0123] <Function of the internally illuminated decorative shelf in the on state of the internal illumination> That is, when the wall-like structure WS is arranged in the indoor space of the specific room and the indoor space is partitioned into a first space S1 and a second space S2, when the lighting fixture in the first space S1 is turned on while the LED line lighting fixtures 41 and 42 are lit to provide an illumination state, in the internal space of the outer frame 10, the space in front of the back plate 31 of the rear door 30 becomes an illuminated space. At this time, the security door structure SS provides a function of an internally illuminated decorative shelf that allows the shelf 31 to be visually recognized by external people as an internally illuminated decorative shelf due to the space in front of the back plate 31 inside the outer frame 10.

[0124] <Function of concealing the key insertion hole by the non-illuminated range of the LED line lighting fixture> Here, the illumination range by both the LED line illumination device 41 and the LED line illumination device 42 is an illumination range LA that illuminates only a predetermined range, as shown by the imaginary line in the plan view in Fig. 7 and the imaginary line in the side view in Fig. 12. The illumination range LA by both the LED line illumination device 41 and the LED line illumination device 42 has an illumination limit LA1 that is a limit position or limit boundary of the illumination range LA on the rear side in the internal space of the outer frame 10. In the security door structure SS of this embodiment, the optical characteristics of the LED line illumination device 41 and the LED line illumination device 42 are set to optical characteristics such that the illumination limit LA1 of the illumination range LA is a position a predetermined distance forward from the front surface of the back panel 31 in the internal space of the outer frame 10. Therefore, in the security door structure SS of this embodiment, the illumination range LA by both the LED line illumination fixtures 41 and 42 does not reach the area behind the illumination limit LA1 in the internal space of the outer frame 10, and even if some illumination light reaches the area behind the illumination limit LA1, the amount of light is not enough to be visually confirmed by a person with normal eyesight. Therefore, in the security door structure SS of this embodiment, the area behind the illumination limit LA1 in the internal space of the outer frame 10 becomes a non-illuminated range NLA where the illumination light by both the LED line illumination fixtures 41 and 42 cannot reach.

[0125] Therefore, in the security door structure SS of this embodiment, the small-diameter circular opening at the front end of the key insertion hole 74, which is a part of the mechanical locking device 70 of the rear door 30, is exposed to the right ends of the upper and lower ends of the back panel 31 in the internal space of the outer frame 10. However, in the internal space of the outer frame 10, the area behind the illumination limit LA1 becomes a non-illuminated range NLA where the illumination light from both the LED line illumination fixtures 41 and 42 cannot reach, so it is very difficult for a person with normal eyesight to visually confirm the key insertion hole 74. Therefore, the security door structure SS of this embodiment exhibits a function of concealing the key insertion hole by the non-illuminated range NLA of the LED line illumination fixtures 41, 42.

[0126] <Touch sensor for electromagnetic lock device> In the security door structure SS of this embodiment, as described above, it is assumed that when an administrator opens the rear door 30 to enter the second space S2 (security room), the front door 20 closes accidentally or unintentionally, causing the electromagnetic locking device to lock and place the front door 20 in a locked state. In such a case, a touch switch 91 for unlocking the electromagnetic locking device is provided at a predetermined position on the inner wall surface of the second space S2 (security room) (i.e., the rear surface of the wall structure WS or the rear surface of the display structure DS) so that the administrator in the second space S2 (security room) can unlock the front door 20 from within the second space S2 (security room), as shown in Figure 19.

[0127] <Another Example of the Invention> In the security door structure of the present invention, in addition to configuring the rear door, which serves as the second security door, in the internal space of the outer frame as an internally illuminated display shelf consisting of a back panel and a shelf panel as in the first embodiment, the rear door, which serves as the second security door, in the internal space of the outer frame can be configured from the back panel of the wardrobe structure RS shown in the first embodiment (in this case too, the door of the wardrobe structure RS consists of a frame and a functional panel and functions as the first security door), the rear door, which serves as the second security door, can be configured from the back panel of the cabinet structure CS shown in the first embodiment (in this case too, the door of the cabinet structure CS consists of a frame and a functional panel and functions as the first security door), or the rear door, which serves as the second security door, in the internal space of the outer frame can be configured from the back panel of another furniture structure having a back panel (in this case too, the door at the opening at the front of the furniture structure consists of a frame and a functional panel and functions as the first security door).
