[0011] Hereinafter, an equipment module and a wiring device system including the same according to an embodiment will be described in detail with reference to the drawings. However, each diagram described in the following embodiments is a schematic diagram, and the dimensional ratios of the sizes of the components do not necessarily reflect the actual dimensional ratios. Furthermore, the configurations described in the following embodiments are merely examples of the present disclosure. The present disclosure is not limited to the following embodiments, and various modifications are possible depending on the design, etc., as long as the effects of the present disclosure can be achieved.

[0012] (Embodiment) (1) Overview As shown in FIGS. 1 and 2, the device module 2 according to this embodiment includes a mounting member 3, an electric device 4, and a cover member 5.

[0013] As shown in Figures 5, 7 and 8, the mounting member 3 has an insertion piece 31 that is inserted between the mounting frame 7 and the construction material 100. The mounting member 3 can be attached to the construction material 100 with the insertion piece 31 inserted between the mounting frame 7 and the construction material 100. The mounting frame 7 is formed in a frame shape with a rectangular mounting hole 73. The mounting frame 7 holds the wiring device 6 placed in the mounting hole 73. The mounting frame 7 is attached to the construction material 100 with part of the wiring device 6 housed in an embedding hole 101 (see Figures 6 and 7) provided in the construction material 100.

[0014] The electrical equipment 4 is placed on the opposite side of the mounting member 3 from the construction material 100 .

[0015] The cover member 5 is attached to the mounting member 3 with an accommodation space SP1 (see FIGS. 2 and 9) for accommodating the electric device 4 formed between the cover member 5 and the mounting member 3.

[0016] The cover member 5 is provided with window holes 52 and 53 for exposing the wiring fixture 6 and the electrical device 4, respectively.

[0017] When the mounting member 3 is attached between the mounting frame 7 and the construction material 100, a recess 32 that connects to the mounting hole 73 is provided in the mounting member 3.

[0018] Here, the mounting member 3 is formed in a plate shape, and is attached to the construction material 100 so that the thickness direction of the mounting member 3 is along the normal direction to the surface of the construction material 100. The mounting member 3 has a first surface 301 and a second surface 302 that face each other in the thickness direction. In the mounting member 3, the first surface 301 that faces the surface of the construction material 100 is the rear surface, and the second surface 302 opposite the first surface 301 is the front surface.

[0019] In the device module 2 of this embodiment, the mounting member 3 is attached to the construction material 100 with the insertion piece 31 of the mounting member 3 inserted between the mounting frame 7 and the construction material 100. Then, when the cover member 5 is attached to the mounting member 3, the electrical device 4 is accommodated in the accommodation space SP1 provided between the cover member 5 and the mounting member 3. Therefore, when the electrical device 4 is installed next to the wiring device 6 installed on the construction material 100 using the mounting frame 7, there is no need to provide a hole in the construction material 100 for burying a portion of the electrical device 4. Therefore, the device module 2 of this embodiment has the advantage of simplifying the task of installing the electrical device 4 next to the wiring device 6 on the construction material 100. Another advantage is that installing the electrical device 4 next to the wiring device 6 that the user uses on a daily basis improves the usability of the electrical device 4. For example, if the electrical device 4 is a display device, there is the advantage of reducing the likelihood that the user will overlook information (e.g., a to-do list) displayed on the screen of the electrical device 4.

[0020] The wiring device system 1 of this embodiment also includes an equipment module 2, a mounting frame 7, and a wiring device 6 attached to the mounting frame 7.

[0021] The wiring device system 1 includes a wiring device 6 that is attached to the construction material 100 using a mounting frame 7, and the above-mentioned equipment module 2, so that the task of installing the electrical equipment 4 alongside the wiring device 6 on the construction material 100 can be easily performed.

[0022] (2)Details The device module 2 according to this embodiment and the wiring device system 1 including the same will be described in more detail below with reference to FIGS.

[0023] (2.1) Configuration As described above, the device module 2 includes the mounting member 3, the electric device 4, and the cover member 5.

[0024] As described above, the wiring device system 1 including the device module 2 includes the device module 2, the mounting frame 7 to which the mounting member 3 of the device module 2 is attached, and the wiring device 6. In this embodiment, the wiring device system 1 further includes a plate frame 8 attached to the front side of the mounting frame 7. In this embodiment, the wiring device 6 is, for example, a switch, and includes a switch main body 60 and an operating handle 9 for operating the switch main body 60.

[0025] The configuration of each part of the wiring device system 1 including the device module 2 will be described in more detail below with reference to Figures 1 to 10. In the following description, the X-axis direction in Figure 1 and other figures is defined as the left-right direction, the Y-axis direction as the front-rear direction (depth direction), and the Z-axis direction as the up-down direction. Furthermore, the positive direction of the X-axis direction is defined as the right side, the positive direction of the Y-axis direction as the front side, and the positive direction of the Z-axis direction as the top side. However, these directions are merely examples and are not intended to limit the directions in which the device module 2 and the wiring device system 1 are used. Furthermore, the arrows indicating the various directions in the drawings are merely shown for explanatory purposes and do not have any substance.

[0026] (2.1.1) Mounting frame The mounting frame 7 is used to mount the embedded wiring device 6 in a state where a part (rear part) of the embedded wiring device 6 is embedded in an embedding hole 101 provided in the construction material 100.

[0027] The material of the mounting frame 7 includes, for example, metal. In this embodiment, the entire mounting frame 7 is made of a metal material.

[0028] The mounting frame 7 is a rectangular frame with its long sides extending in the vertical direction. The mounting frame 7 has rectangular mounting holes 73 with their long sides extending in the vertical direction. The mounting frame 7 also has a pair of first sides 71 extending along the longitudinal direction of the mounting holes 73, and a pair of second sides 72 extending along the lateral direction of the mounting holes 73. The upper ends of the pair of first sides 71 are connected via the second side 72 located above, and the lower ends of the pair of first sides 71 are connected via the second side 72 located below.

[0029] A rearward-protruding rib 77 is provided on each of the pair of first sides 71. Each of the pair of ribs 77 is provided with three pairs of locking holes 76, into which two locking projections 63 provided on the side surface of the wiring fixture 6 are respectively fitted.

[0030] Each of the pair of second sides 72 is provided with an elongated hole 74 for inserting a fixing screw 111 for fixing the mounting frame 7 to an embedded box (not shown) embedded in the construction material 100 (see FIGS. 6 and 7). Also, each of the pair of second sides 72 is provided with a screw hole 75 for screwing in a plate fixing screw for attaching a plate frame 8 that is placed on top of the front side of the mounting frame 7.

[0031] The material of the mounting frame 7 may include synthetic resin, and the entire mounting frame 7 may be made of synthetic resin.

[0032] (2.1.2) Plate frame The plate frame 8 is formed into a rectangular frame shape from, for example, synthetic resin.

[0033] The plate frame 8 is disposed on top of the front side of the mounting frame 7. The plate frame 8 has a rectangular window hole 81 in which the operating handle 9 of the wiring device 6 is disposed. The vertical dimension of the window hole 81 is larger than that of the mounting hole 73 of the mounting frame 7, and the horizontal dimension of the window hole 81 is larger than that of the mounting hole 73 of the mounting frame 7.

[0034] The upper and lower edges of the plate frame 8 are each provided with through holes 82 into which plate fixing screws for fixing the plate frame 8 to the mounting frame 7 are inserted.

[0035] Furthermore, the left and right sides of the plate frame 8 are each provided with three holes 83 into which the coupling claws 56 provided on the rear surface of the cover member 5 are inserted and coupled.

[0036] (2.1.3) Wiring devices The wiring device 6 is, for example, a switch, and includes a switch body 60 and an operating handle 9 (see FIGS. 1 and 2).

[0037] The switch body 60 is rectangular and is formed by joining a front cover and a rear body, each of which is a synthetic resin molded product. The widthwise dimension of the switch body 60 is formed to be large enough to allow up to three units to be attached to a mounting frame used when installing a flush-mounted wiring device known as a large-angle connecting type (see JIS C8304). The lengthwise dimension of the mounting hole 73 in the mounting frame 7 is set equal to the lengthwise dimension of the mounting hole in the mounting frame used when installing the flush-mounted wiring device. Therefore, the widthwise dimension of the switch body 60 is approximately one-third the lengthwise dimension of the mounting hole 73 in the mounting frame 7. This dimension, like that of a large-angle connecting type wiring device, is called the "module dimension."

[0038] The back surface of the switch body 60 has two wire insertion holes 64 on each of the left and right sides for inserting wires from the outside (see FIG. 5). A pair of shafts 62 that rotatably support the operating handle 9 are provided at the left end of the front surface of the switch body 60. The front ends of the pair of shafts 62 are formed in a cylindrical shape along the short direction of the front surface of the switch body 60. A push button 61 is arranged on the right side of the front surface of the switch body 60 so as to be movable in the front-rear direction.

[0039] The switch body 60 also contains a pair of connection terminals 65 to which the wires inserted through the wire insertion holes 64 are electrically connected, and a contact 66 electrically connected between the pair of connection terminals 65 (see FIG. 10). The switch body 60 also contains a switching mechanism that switches the contact 66 between on and off each time the push button 61 is pressed.

[0040] A series circuit of a load L1, such as a lighting fixture, and an AC power source AC is connected to the pair of connection terminals 65 via electric wires. When the switching mechanism switches the contacts 66 from off to on, power is supplied from the AC power source AC to the load L1, causing the load L1 to operate. When the switching mechanism switches the contacts 66 from on to off, the power supply from the AC power source AC to the load L1 is cut off, causing the load L1 to stop operating. Note that the load L1 is not limited to a lighting fixture, and may be a ventilation fan or the like.

[0041] Furthermore, a pair of locking projections 63 is provided on each of the left and right side surfaces of the switch body 60. The switch body 60 is attached to the mounting frame 7 by inserting the pair of locking projections 63 provided on the left and right side surfaces of the switch body 60 into a set of two locking holes 76 provided on each of a pair of ribs 77 of the mounting frame 7. When the switch body 60 is attached to the mounting frame 7, the switch body 60 is positioned in the mounting hole 73, and the front surface of the switch body 60 is exposed forward from the mounting hole 73.

[0042] The operating handle 9 is a molded synthetic resin product. When viewed from the front, the operating handle 9 has a rectangular shape. The size of the front surface of the operating handle 9 is set to be larger than the mounting hole 73 of the mounting frame 7 and slightly smaller than the window hole 81 of the plate frame 8.

[0043] A bearing portion 91 (see FIG. 2) into which the pair of shaft portions 62 are fitted is provided on the left side of the rear surface of the operating handle 9. A pair of retaining pieces 92 (see FIG. 2) that protrude rearward are provided on the right end of the rear surface of the operating handle 9.

[0044] By fitting the pair of shafts 62 into the bearings 91 of the operating handle 9, the operating handle 9 is attached to the switch body 60 in a state where it can rotate around the pair of shafts 62. Furthermore, with the pair of shafts 62 fitted into the bearings 91 of the operating handle 9, the pair of retaining pieces 92 are inserted into retaining holes provided on the front surface of the switch body 60. Then, protrusions provided on the tips of the retaining pieces 92 catch on the edges of the retaining holes, preventing the right end of the operating handle 9 from coming off the switch body 60.

[0045] When the operating handle 9 is attached to the switch body 60, the operating handle 9 can rotate around a pair of shafts 62. When the right side of the operating handle 9 is pushed backward, the operating handle 9 pushes the push button 61 backward, and the switching mechanism switches the contact 66 from on to off or from off to on.

[0046] (2.1.4) Mounting parts The material of the mounting member 3 includes, for example, metal. In this embodiment, the entire mounting member 3 is formed of a metal material.

[0047] The mounting member 3 is formed by, for example, pressing a metal plate.

[0048] 1, 2, and 6, the mounting member 3 has a rectangular flat plate portion 30. Insertion pieces 31 that protrude leftward are provided at the upper and lower ends of the left end of the flat plate portion 30. The mounting member 3 has a first end 30A where the insertion piece 31 is provided, and a second end 30B opposite the first end 30A in an insertion direction DR1 (see FIG. 6) in which the insertion piece 31 is inserted between the mounting frame 7 and the construction material 100.

[0049] The pair of insertion pieces 31 are inserted between the mounting frame 7 and the construction material 100. More specifically, the pair of insertion pieces 31 are inserted between the pair of second sides 72 of the mounting frame 7 and the construction material 100, respectively. Each of the pair of insertion pieces 31 is provided with a U-shaped insertion groove 33 into which a fixing screw 111 for fixing the mounting frame 7 to the construction material 100 can be inserted. That is, the insertion piece 31 is provided with the insertion groove 33 into which a fixing screw 111 for fixing the mounting frame 7 to the construction material 100 can be inserted. The insertion groove 33 is provided in a portion of the insertion piece 31 that overlaps with the elongated hole 74 of the second side 72, so that when the insertion piece 31 is inserted between the mounting frame 7 and the construction material 100, the fixing screw 111 inserted into the elongated hole 74 of the mounting frame 7 can be inserted into the insertion groove 33. Therefore, without removing the fixing screws 111, the insertion piece 31 can be inserted between the mounting frame 7 and the construction material 100 by loosening the fixing screws 111 and creating a gap between the mounting frame 7 and the construction material 100. In the installation example of FIG. 6 , the insertion piece 31 of the mounting member 3 is inserted between the mounting frame 7 and the construction material 100 from the right side of the mounting frame 7, so that the flat portion 30 of the mounting member 3 is positioned on the right side of the mounting frame 7. Therefore, the electrical device 4 is positioned on the right side of the wiring fixture 6. Note that the insertion piece 31 of the mounting member 3 may also be inserted between the mounting frame 7 and the construction material 100 from the left side of the mounting frame 7, in which case the flat portion 30 of the mounting member 3 is positioned on the left side of the mounting frame 7. Therefore, the electrical device 4 is positioned on the left side of the wiring fixture 6.

[0050] When the pair of insertion pieces 31 are inserted between the mounting frame 7 and the construction material 100, the rib 77 provided on the first side 71 of the mounting frame 7 comes into contact with the contact portion 37, which is the left edge of the flat plate portion 30. That is, in the insertion direction DR1 in which the insertion pieces 31 are inserted between the mounting frame 7 and the construction material 100, the mounting member 3 is provided with a contact portion 37 that comes into contact with the rib 77 that protrudes from the mounting frame 7 toward the construction material 100. By inserting the insertion pieces 31 between the mounting frame 7 and the construction material 100 until the contact portion 37 of the flat plate portion 30 comes into contact with the rib 77 of the mounting frame 7, the mounting member 3 can be positioned at a predetermined position relative to the mounting frame 7.

[0051] Furthermore, a recess 32 is provided on the left side of the mounting member 3 between the pair of insertion pieces 31. When the insertion piece 31 is inserted between the mounting frame 7 and the construction material 100 to a position where the rib 77 of the mounting frame 7 contacts the contact portion 37, the mounting hole 73 of the mounting frame 7 overlaps the recess 32. In other words, the mounting member 3 has two insertion pieces 31 on both sides of the recess 32. The peripheral portion of the recess 32 of the mounting member 3 faces three sides of the pair of first sides 71 and the pair of second sides 72. The peripheral portion of the recess 32 includes two insertion pieces 31. In the installation example of FIG. 6 , the insertion piece 31 of the mounting member 3 is inserted between the mounting frame 7 and the construction material 100 from the right side of the mounting frame 7. Therefore, when the insertion piece 31 is inserted between the mounting frame 7 and the construction material 100, the area around the recess 32 of the mounting member 3 overlaps three sides, namely the first side 71 and the pair of second sides 72 on the right side. In addition, it is also possible to insert the insertion piece 31 of the mounting member 3 between the mounting frame 7 and the construction material 100 from the left side of the mounting frame 7, in which case the area around the recess 32 in the mounting member 3 faces three sides, namely the first side 71 on the left side and a pair of second sides 72.

[0052] Furthermore, protrusions 36 that come into contact with the side surfaces of the plate frame 8 are provided on the upper and lower edges of the flat plate portion 30 of the mounting member 3 by cutting out and raising parts of the flat plate portion 30. That is, in the insertion direction DR1 in which the insert pieces 31 are inserted between the mounting frame 7 and the construction material 100, the protrusions 36 that come into contact with the side surfaces of the plate frame 8 attached to the mounting frame 7 so as to cover the mounting frame 7 are provided on the mounting member 3. When the insert pieces 31 are inserted between the mounting frame 7 and the construction material 100, the contact portions 37 come into contact with the ribs 77 of the mounting frame 7, and the protrusions 36 come into contact with the side surfaces of the plate frame 8. Therefore, by inserting the insert pieces 31 between the mounting frame 7 and the construction material 100 until the contact portions 37 of the flat plate portion 30 come into contact with the ribs 77 of the mounting frame 7 and the protrusions 36 come into contact with the side surfaces of the plate frame 8, the mounting member 3 can be positioned at a predetermined position relative to the mounting frame 7.

[0053] Furthermore, the second end of the mounting member 3 is provided with a plurality of (e.g., four) ribs spaced apart in the vertical direction, and each of the plurality of ribs is provided with an insertion hole 34 for inserting a fastener 112 for fixing the mounting member 3 to the construction material 100. That is, the second end 30B of the mounting member 3 is provided with an insertion hole 34 for inserting a fastener 112 for fixing the second end 30B to the construction material 100. The fastener 112 is, for example, a pin or a nail. With the insertion piece 31 inserted between the mounting frame 7 and the construction material 100, the fixing screw 111 inserted into the elongated hole 74 is screwed into the screw hole of the embedded box, thereby clamping the insertion piece 31 between the mounting frame 7 and the construction material 100. Then, when the fastener 112 inserted into the insertion hole 34 is driven into the construction material 100, the second end 30B of the mounting member 3 is fixed to the construction material 100, and the mounting member 3 can be firmly fixed to the construction material 100.

[0054] Furthermore, the second end 30B of the mounting member 3 is provided with second coupling portions 35 that can be coupled to first coupling portions 59 provided on the cover member 5. A plurality of (e.g., three) first coupling portions 59 are provided on the inner surface of the side wall 51 (the right side wall 51 in the installation example of FIG. 3 ) of the four side walls 51 of the cover member 5 that is adjacent to the electrical device 4 (see FIG. 5 ). Each of the plurality of first coupling portions 59 is a protrusion provided on the inner surface of the side wall 51, and this protrusion has a triangular shape when viewed from above. Meanwhile, the second end 30B of the mounting member 3 is provided with a plurality of (e.g., three) second coupling portions 35 that can be coupled to the plurality of (e.g., three) first coupling portions 59 provided on the cover member 5, respectively. Each of the plurality of second coupling portions 35 is formed by bending a strip-shaped plate piece protruding from the second end 30B of the mounting member 3. Each of the multiple second coupling portions 35 has a sideways V-shape when viewed from above, with the intermediate portion in the front-to-rear direction protruding outward (away from the first end 30A) compared to both ends in the front-to-rear direction. When the cover member 5 is brought closer to the mounting member 3 from the front, the second coupling portions 35 come into contact with the first coupling portions 59, causing the second coupling portions 35 to bend inward. When the cover member 5 is further pushed closer to the mounting member 3, the second coupling portions 35 climb over the first coupling portions 59 and become engaged with the first coupling portions 59, thereby holding the cover member 5 to the mounting member 3. In this embodiment, three second coupling portions 35 are provided at the second end 30B of the mounting member 3, and the three second coupling portions 35 are provided at the top, bottom, and middle of the second end 30B. Furthermore, in this embodiment, five insertion holes 34 are provided in the second end 30B of the mounting member 3, and the five insertion holes 34 are provided in positions different from the three second coupling portions 35. Because the five insertion holes 34 are provided in positions different from the three second coupling portions 35, it is possible to reduce the possibility of interference between the fasteners 112 inserted into the five insertion holes 34 and the three second coupling portions 35. Note that, although in this embodiment the first coupling portion 59 is a protrusion and the second coupling portion 35 is configured with a spring piece that engages with the protrusion, the second coupling portion 35 may also be a protrusion and the first coupling portion 59 may also be configured with a spring piece that engages with the protrusion.

[0055] (2.1.5) Electrical Equipment The electrical appliance 4 includes, for example, a display device 42 that can display visual information. The display device 42 has a control unit 421, a display unit 422, and a communication unit 423, as shown in FIG.

[0056] The electrical device 4 further includes a substrate 41 having a display device 42 and the like mounted on the front surface thereof. A socket-side connector 44 conforming to the USB (registered trademark) standard, for example, is mounted on the left end of the lower part of the front surface of the substrate 41.

[0057] The display unit 422 of the display device 42 has, for example, electronic paper capable of displaying two colors, white and black. The screen 43 of the display unit 422 is exposed through a window hole 53 in the cover member 5. The electronic paper is a self-holding display device that consumes operating power when rewriting an image but does not require operating power to maintain the image displayed on the screen 43. The screen 43 is a well-known touch panel such as a resistive film type, a capacitive type, or an electromagnetic induction type. The user can touch (tap) the screen 43 with a finger or a pen. When the user touches the screen 43 with a finger or a pen, operation data corresponding to the touch operation is output from the touch panel to the control unit 421.

[0058] The substrate 41 is attached to the back surface of the front wall 50 of the cover member 5 with the mounting surface for the display device 42 and the like facing forward. Through holes 45 into which mounting screws can be inserted are provided at the four corners of the substrate 41 (see FIG. 2). Four tapping screws are inserted into the four through holes 45, respectively, and then screwed into holes in four bosses 57 (see FIG. 2) provided on the back surface of the front wall 50 of the cover member 5, thereby attaching the substrate 41 to the back surface of the front wall 50 of the cover member 5.

[0059] When the substrate 41 is attached to the cover member 5, the screen 43 of the display unit 422 of the display device 42 is exposed through the window hole 53 of the cover member 5. Here, the size of the screen 43 of the display device 42 is approximately the same as the size of the operating handle 9 of the wiring device 6. Since the screen 43, which is approximately the same size as the operating handle 9, and the operating handle 9 are lined up in the left-right direction, there is an advantage in that the design of the wiring device system 1 is improved.

[0060] Furthermore, when the substrate 41 is attached to the cover member 5 , the connector 44 is disposed at a position facing a connector connection hole 54 provided in the lower side wall 51 of the cover member 5 .

[0061] Here, when the plug-side connector provided on the electric wire from the host system 200 is connected to the connector 44 through the connector connection hole 54, the host system 200 and the electrical device 4 are connected via the electric wire. The electric wire from the host system 200 is placed on the surface of the construction material 100 and is protected by a cable molding or the like. When the host system 200 and the electrical device 4 are connected via the electric wire, power is supplied from the host system 200 to the electrical device 4, and the electrical device 4 becomes operable. Furthermore, when the host system 200 and the electrical device 4 are connected via the electric wire, the host system 200 and the communication unit 423 become capable of communicating via the electric wire.

[0062] The control unit 421 is mainly composed of a computer system having one or more processors and a memory. The functions of the control unit 421 are realized by the processor of the computer system executing a program recorded in the memory of the computer system. The program may be recorded in the memory, or may be provided via a telecommunications line such as the Internet, or may be recorded on a non-transitory recording medium such as a memory card and provided.

[0063] When the communication unit 423 receives screen data from the host system 200, the control unit 421 controls the display content of the display unit 422 based on the screen data from the host system 200. Furthermore, when the user performs a touch operation on the screen 43 with a finger, a pen, or the like, the control unit 421 causes the communication unit 423 to transmit operation data indicating the operation content of the touch operation to the host system 200. When the host system 200 receives the operation data from the electrical appliance 4, the host system 200 performs a predetermined process based on the operation data. The predetermined process is, for example, a process of switching the screen displayed on the display unit 422, but may also be a process of outputting screen data requested by the user.

[0064] When the wiring device system 1 of the present embodiment is installed in each dwelling unit of an apartment building, for example, the host system 200 is a server operated by a management company of the apartment building or an owner of the rental apartment building. The host system 200 transmits image data to the electrical device 4 for notifying the residents of each dwelling unit of the apartment building of guidance information. The control unit 421 of the electrical device 4 causes a display screen that visually displays the guidance information based on the image data from the host system 200 to be displayed on the screen 43. The users who are residents of each dwelling unit can understand the guidance information for the residents by viewing the display screen displayed on the screen 43. Note that the guidance information for the residents may include, for example, information related to management of the apartment building, such as garbage collection dates and information related to apartment building maintenance, and information such as a to-do list registered by the residents in the host system 200 using a mobile device such as a smartphone. The guidance information for the residents may also include date and time information related to the current date and time, weather information related to the weather in the area where the apartment building is located, and the like.

[0065] Some visual information is always displayed on the screen 43 of the display device 42, but because the display device 42 is electronic paper, it is possible to reduce the power consumption of the display device 42. Furthermore, even in the event of a power outage, the screen 43 of the display device 42 continues to display the visual information that is currently being displayed, so the visual information displayed on the screen 43 can be confirmed even during a power outage.

[0066] In this embodiment, the screen 43 of the display device 42 is placed next to the wiring fixture 6, which is a switch for a lighting fixture or the like, so that the user can check the visual information displayed on the screen 43 when operating the wiring fixture 6.

[0067] If communication between the communication unit 423 and the host system 200 is interrupted, the control unit 421 may display information on the screen 43 indicating that communication with the host system 200 is unavailable. If communication between the communication unit 423 and the host system 200 is interrupted, the control unit 421 may display information on contact information for a management company or the like on the screen 43. If communication between the communication unit 423 and the host system 200 is interrupted, the control unit 421 may display a two-dimensional code on the screen 43 for accessing a web page that displays guidance information for the user. When the two-dimensional code displayed on the screen 43 is read by a mobile terminal such as a smartphone, a web page that displays guidance information for the user is displayed on the screen of the mobile terminal. Therefore, the user can check the guidance information displayed on the web page by viewing the web page displayed on the screen of the mobile terminal. If communication between the communication unit 423 and the host system 200 is interrupted, the information that the control unit 421 displays on the screen 43 of the display unit 422 may be stored in advance in the memory of the electrical appliance 4.

[0068] (2.1.6) Cover member The cover member 5 is, for example, a molded product made of synthetic resin.

[0069] The cover member 5 includes a front wall 50 having a horizontally long rectangular shape when viewed from the front, and four side walls 51 protruding rearward from four sides of the front wall 50.

[0070] The front wall 50 is provided with a window hole 52 for exposing the wiring fixture 6 and a window hole 53 for exposing the electrical device 4. In this embodiment, the operating handle 9 of the wiring fixture 6 is exposed through the window hole 52, and the screen 43 of the electrical device 4 is exposed through the window hole 53.

[0071] Four bosses 57 are provided on the rear surface of the front wall 50 at positions corresponding to the four through holes 45 provided in the base plate 41 of the electric device 4. The electric device 4 is attached to the cover member 5 by threading a tapping screw inserted into each of the four through holes 45 into the corresponding hole of the boss 57.

[0072] Additionally, six coupling claws 56 (fourth coupling portions) are provided on the rear surface of the front wall 50 at positions facing six holes 83 (third coupling portions) provided in the plate frame 8. That is, the cover member 5 is provided with fourth coupling portions (e.g., coupling claws 56) that can be coupled to third coupling portions (e.g., holes 83) provided in the plate frame 8 that is attached to the mounting frame 7 so as to cover the mounting frame 7. Note that in this embodiment, the holes 83 in the plate frame 8 serve as the third coupling portions and the coupling claws 56 of the cover member 5 serve as the fourth coupling portions, but the fourth coupling portions of the cover member 5 may be holes and the third coupling portions of the plate frame 8 may be coupling claws that fit into the holes.

[0073] Furthermore, a first coupling portion 59 is provided on the inner surface of the side wall 51 of the cover member 5 on the side of the electric device 4 at a position corresponding to the second coupling portion 35 of the mounting member 3.

[0074] Furthermore, the upper and lower side walls 51 of the cover member 5 are provided with connector connection holes 54, 55 for exposing the connector 44 of the electrical device 4. As shown in Fig. 3 , when the insertion piece 31 of the mounting member 3 is inserted into the mounting frame 7 from the right side, the electrical device 4 is disposed on the right side of the wiring fixture 6, and the connector 44 of the electrical device 4 faces the connector connection hole 54 of the lower side wall 51. In this case, a lid member 58 is attached to the connector connection hole 55 of the upper side wall 51, and the lid member 58 closes the connector connection hole 55.

[0075] When the insertion piece 31 of the mounting member 3 is inserted into the mounting frame 7 from the left side, the electric device 4 is disposed on the left side of the wiring fixture 6, and therefore the cover member 5 is attached to the mounting member 3 with the window hole 52 located on the right side and the window hole 53 located on the left side. In this case, the cover member 5 is upside down compared to the orientation shown in Figures 1 to 3, and the connector 44 of the electric device 4 faces the connector connection hole 55 of the side wall 51 located on the lower side. Then, a lid member 58 is attached to the connector connection hole 54 of the side wall 51 located on the upper side, and the connector connection hole 54 is closed by the lid member 58.

[0076] (2.2) How to install the equipment module The method of attaching the device module 2 will be described below with reference to FIGS. 6 to 8 and other figures.

[0077] The following describes a method for attaching the equipment module 2 to the mounting frame 7 when the wiring fixture 6 is attached to the construction material 100 via the mounting frame 7. It is assumed that a plate frame 8 is attached to the front side of the mounting frame 7.

[0078] First, the user removes the operating handle 9 from the switch body 60, and loosens the fixing screw 111 to provide a gap between the mounting frame 7 and the construction material 100 for the insertion piece 31 to fit into.

[0079] Next, the user inserts the pair of insertion pieces 31 of the mounting member 3 from the right side of the mounting frame 7 into the gap between the mounting frame 7 and the construction material 100. Then, the user aligns the mounting member 3 with respect to the mounting frame 7 so that the pair of insertion pieces 31 are inserted behind the pair of second sides 72, and inserts the mounting member 3 along the insertion direction DR1. The fixing screw 111 then fits into the insertion groove 33 of the insertion piece 31. The user then inserts the mounting member 3 along the insertion direction DR1 until the contact portion 37 of the mounting member 3 contacts the rib 77 of the mounting frame 7 and the protrusion 36 of the mounting member 3 contacts the side of the plate frame 8. The user then tightens the fixing screw 111 to fix the mounting frame 7 to the construction material 100 with the insertion pieces 31 sandwiched between the mounting frame 7 and the construction material 100, thereby fixing the mounting frame 7 and the mounting member 3 to the construction material 100. The user also fixes the second end 30B side of the mounting member 3 to the construction material 100 by driving the fastener 112 inserted into the insertion hole 34 of the mounting member 3 into the construction material 100.

[0080] The user places the electrical device 4 on the back side of the front wall 50 of the cover member 5 so that the screen 43 is exposed through the window hole 53, and then fixes the electrical device 4 to the cover member 5 by screwing a tapping screw inserted into the through hole 45 of the board 41 into the hole of the boss 57. The user then places the cover member 5 holding the electrical device 4 over the front sides of the plate frame 8 and the mounting member 3, and engages the coupling claws 56 of the cover member 5 with the holes 83 of the plate frame 8 and the first coupling portion 59 of the cover member 5 with the second coupling portion 35 of the mounting member 3. This attaches the cover member 5 to the plate frame 8 and the mounting member 3. With the cover member 5 attached to the plate frame 8 and the mounting member 3, the operating handle 9 of the wiring device 6 is exposed through the window hole 52, and the screen 43 of the electrical device 4 is exposed through the window hole 53. This allows the user to operate the operating handle 9 exposed through the window hole 52 and view the screen 43 exposed through the window hole 53.

[0081] As described above, the method for installing the equipment module 2 includes four steps. The first step is inserting the insertion piece 31 of the mounting member 3 between the mounting frame 7 and the construction material 100. The second step is fixing the mounting frame 7 to the construction material 100 with the insertion piece 31 inserted between them. The third step is attaching the electrical equipment 4 to the cover member 5. The fourth step is connecting the first connecting portion 59 on the cover member 5 to the second connecting portion 35 on the mounting member 3. In this way, the mounting member 3 is fixed to the construction material 100 by sandwiching the insertion piece 31 between the mounting frame 7 and the construction material 100. Because the electrical equipment 4 is attached to the construction material 100 via the mounting member 3, there is no need to embed the wiring fixture 6 in the construction material 100 to install the equipment module 2. This allows for easy installation of the electrical device 4 alongside the wiring device 6 on the construction material 100. In this embodiment, the electrical device 4, which is the display device 42, is installed alongside the wiring device 6, which is a switch for a lighting fixture or the like that is used daily by the user, thereby reducing the possibility that the user will overlook information displayed on the screen 43 of the display device 42 (for example, guidance information such as a ToDo list).

[0082] The method for attaching the equipment module 2 further includes the step of attaching a fourth coupling portion (e.g., coupling claw 56) provided on the cover member 5 to a third coupling portion (e.g., hole 83) of the plate frame 8 attached to the mounting frame 7 so as to cover the mounting frame 7. In this way, the cover member 5 and the plate frame 8 are coupled together by coupling the coupling claw 56 provided on the rear surface of the cover member 5 to the hole 83 of the plate frame 8, so that the cover member 5 can be attached to the plate frame 8 without using tools or the like.
