Description

[Technical field]

[0001] The present disclosure relates to an equipment plate for a system ceiling, the equipment plate being for installing equipment such as an emergency light, and a lighting system. [Background technology]

[0002] Conventionally, equipment such as emergency lights, sprinklers, and speakers are installed in a system ceiling while attached to an equipment plate, also called an equipment mounting panel, for installing the equipment. Some equipment plates have fixing members for fixing the equipment attached to the back surface, which is the back surface and not the design surface, of the equipment plate in order to install the equipment (for example, see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 10-271585 Summary of the Invention [Problem to be solved by the invention]

[0004] The equipment plate of Patent Document 1 has a pair of mounting bases for installing equipment or a pair of mounting bases of other forms, and it is necessary to use these mounting bases in accordance with equipment of different specifications. Patent Document 1 also discloses an embodiment of an equipment plate for a system ceiling in which a pair of mounting holes for speakers overlap with the upper surface of the equipment plate or are located near the upper surface of the equipment plate. However, the equipment plate for a system ceiling of Patent Document 1 cannot be used in cases that deviate from this installation condition, such as when installing small equipment. That is, the conventional equipment plate requires preparation of fixing members with different specifications (dimensions) in accordance with the dimensions of the equipment. Therefore, conventional equipment plates, such as the equipment plate for a system ceiling of Patent Document 1, are inefficient because it requires a lot of work to design, manufacture, and manage the fixing members and to assemble the equipment plate.

[0005] The present disclosure is intended to solve the above-mentioned problems, and aims to provide an efficient equipment plate and lighting system that does not require much effort in designing, manufacturing, and managing fixing members, and in assembling the equipment plate. [Means for solving the problem]

[0006] The equipment plate according to the present disclosure is an equipment plate for mounting equipment to a system ceiling, and is formed in a box shape with an open upper surface side, and includes a plate body on which the equipment is placed, and a mounting member on which the equipment is mounted, which is formed in a box shape with an open lower surface side, and includes a plurality of installation bases attached to the plate body, and the plate body is formed in a rectangular plate shape in a plan view, and includes a main body part having at least one equipment installation section formed of at least one through hole in the portion where the equipment is placed, and a side wall provided to extend upward along the periphery of the main body part. Each of the multiple installation bases is arranged to extend between a pair of main body sides that are located on opposing sides of the main body part, and each of the multiple installation bases is formed in a rectangular plate shape that is smaller than the main body part in a plan view, and has a base main part to which equipment is attached, and multiple base sides that form side walls that extend downward along the periphery of the base main part, and each of the multiple installation bases is arranged on both sides of the equipment installation part, and at least one of the multiple base sides and at least one of the multiple main body sides are fixed.

[0007] The lighting system of the present disclosure is a lighting system to be attached to a system ceiling, and comprises an equipment plate of the above-mentioned configuration, and a lighting device having a box-shaped fixture body and at least one luminaire attached to the fixture body, wherein the fixture body has at least one frame body formed in a box shape to which the at least one luminaire is attached, and the fixture body has at least one frame body formed in a box shape, and the equipment plate is arranged adjacent to the at least one frame body inside the fixture body. Effect of the Invention

[0008] According to the present disclosure, the equipment plate is formed in a box-like shape with an opening on the bottom side, and includes a plurality of installation bases attached to the plate body. Each of the plurality of installation bases is disposed so as to extend between a pair of main body side parts located on opposing sides of the main body part among the plurality of main body side parts. Each of the plurality of installation bases is disposed on both sides of the equipment installation part, and at least one of the plurality of base side parts and at least one of the plurality of main body side parts are fixed. The equipment plate can accommodate the installation of equipment of different dimensions by fixing a plurality of installation bases of the same structure to the main body side parts by changing the distance from the equipment installation part. Therefore, the equipment plate does not require the design, manufacture, and management of the installation base, which is a fixing member, for each equipment of different dimensions, and is efficient because it does not require laborious assembly of the equipment plate, since it is only necessary to change the fixing position of the installation base and fix it.

[0013] The Y-axis direction is parallel to the longitudinal direction of a later-described equipment plate 200 for a system ceiling, and the X-axis direction is parallel to the lateral direction of the equipment plate 200 for a system ceiling. The X1 direction, X2 direction, Y1 direction, Y2 direction, Z1 direction, and Z2 direction indicate directions in a state in which the lighting system 10, the lighting device 100, and the ceiling equipment plate 200 are attached to a ceiling. Hereinafter, the configurations of the lighting system 10 and the lighting device 100 will be described with reference to the drawings.

[0014] The lighting system 10 is a lighting system that is attached to a so-called system ceiling. A system ceiling is a type of suspended ceiling. A system ceiling is composed of, for example, bar members 300 arranged in a grid pattern as a ceiling frame, and a ceiling panel (not shown) that engages with and is placed on the bar members 300. A system ceiling has a function of facilitating the installation of equipment such as lighting fixtures or air conditioners. The lighting system 10 is used in a state where it is attached to the bar members 300 that the system ceiling has. The bar members 300 are formed in a lattice pattern.

[0015] The bar member 300 includes a plurality of first bar members 301 and a plurality of second bar members 302. The plurality of first bar members 301 are arranged parallel to one another at regular intervals. The plurality of second bar members 302 are arranged parallel to one another at regular intervals so as to intersect with the plurality of first bar members 301. The plurality of first bar members 301 and the plurality of second bar members 302 are formed in the shape of long plates.

[0016] The bar member 300 is joined to, for example, each of a plurality of hanging bolts embedded in the ceiling of a building. By arranging the plurality of first bar members 301 and the plurality of second bar members 302 in parallel at equal intervals, a plurality of substantially square spaces are formed in the bar member 300 so as to be arranged in a lattice pattern. Note that the bar member 300 is not an essential component of the lighting system 10.

[0017] The lighting system 10 includes a lighting device 100 having a fixture body 110 formed in a box shape and at least one luminaire 120 attached to the fixture body 110, and a facility plate 200 for a system ceiling.

[0018] The fixture body 110 of the lighting device 100 has at least one frame body 115 formed in a box shape, to which at least one luminaire 120 is attached. In the lighting system 10, the equipment plate 200 is disposed inside the fixture body 110 adjacent to the at least one frame body 115.

[0019] 1 and 2, the fixture body 110 of the lighting device 100 has two frame bodies 115. The facility plate 200 is disposed in the space S between the two frame bodies 115 inside the fixture body 110.

[0020] [Lighting device 100] The lighting device 100 is an example of a lighting device installed on a system ceiling. The lighting device 100 is a device that supplies light to a space such as a room. The lighting device 100 is used in a state where it is attached to, for example, a bar member 300 provided on the system ceiling. Note that the lighting device 100 may be attached to the ceiling using another fixing member (not shown).

[0021] As shown in Fig. 1, the lighting device 100 includes a fixture body 110 fixed to a bar member 300, and a plurality of luminaires 120 detachably attached to the fixture body 110. Also, as shown in Fig. 2, the lighting device 100 includes a plurality of louvers 130 provided on the fixture body 110 to soften the light emitted from the luminaires 120, and a lighting device 140 that supplies power to the luminaires 120 to turn them on.

[0022] The fixture body 110 is formed in a rectangular box shape, for example. As shown in Fig. 1 and Fig. 2, the fixture body 110 includes two frame bodies 111 and two frames 112, and is configured using, for example, a metal plate material or the like. As shown in Fig. 2, the frame body 111 of the fixture body 110 includes a side surface portion 111A surrounding the side portion of the lamp 120, and a top surface portion 111B located above the lamp 120. As an example, the frame body 111 is provided so that the side surface portion 111A and the top surface portion 111B are perpendicular to each other.

[0023] The device main body 110 has two frames 112 connected to a frame main body 111. The device main body 110 has a part of the frame 112 provided at each of both longitudinal ends where the side surface portion 111A of the frame main body 111 is not formed. The device main body 110 has two frame main bodies 111 connected by two frames 112 to form an integrated housing.

[0024] The frame 112 is formed in a long plate shape in the X-axis direction. The frame 112 constitutes the side surfaces of both ends of the frame main body 111 in the longitudinal direction where the side surface portions 111A are not formed. The frame 112 is formed, for example, so as to be perpendicular to the side surface portions 111A and the top surface portion 111B. Note that, although the frame 112 is constituted by one member in Figs. 1 and 2, it may be constituted by a plurality of members divided into, for example, a member constituting the side surface of the frame body 115 described later and a member connecting two frame main bodies 111.

[0025] The device main body 110 includes two frame bodies 115. The frame body 115 is composed of a frame main body 111 and a part of a frame 112. The frame body 115 includes a pair of side portions 111A facing each other in the X-axis direction, a pair of frames 112 facing each other in the Y-axis direction, and a top surface portion 111B. The frame body 115 is configured such that the top surface portion 111B, the side portions 111A, and the frames 112 are mutually orthogonal.

[0026] The frame body 115 is formed by the frame main body 111 and the frame 112 into a box shape with one surface opening on the lower side. A lighting fixture 120 is arranged in a portion surrounded by the side surface portion 111A of the frame main body 111 and the frame 112 of the fixture main body 110 so as to irradiate an opening facing the top surface portion 111B. That is, the lighting device 100 accommodates the lighting fixture 120 inside the frame body 115. The fixture main body 110 accommodates a lighting fixture 120 in each of the two frame bodies 115. The lighting device 100 accommodates two lighting fixtures 120 inside the fixture main body 110.

[0027] The lighting fixture 120 emits light. The lighting fixture 120 is formed in an elongated shape in the Y-axis direction. The lighting device 100 irradiates light into an illumination space such as a room by turning on the elongated lighting fixture 120. The lighting fixture 120 has a light source unit 121 that houses a light source such as an LED (Light Emitting Diode), and a reflector 122 that reflects the light emitted from the light source unit 121. Note that, in the embodiment, the light source of the light source unit 121 is described as an LED, but the light source is not limited to an LED. For example, the lighting fixture 120 may be an embodiment in which an organic EL, a laser, or the like is used as a light source, or a discharge lamp, an incandescent lamp, or the like is used as a light source.

[0028] A rectangular opening 116 is formed on the lower surface side of the frame body 115. A louver 130 is attached to the opening 116 on the lower surface side of the frame body 115. The louver 130 reduces the glare of the light emitted from the lighting fixture 120. The louver 130 is attached to the side surface portion 111A of the fixture body 110. The louver 130 is disposed below the lighting fixture 120.

[0029] The louver 130 includes two louver connecting pieces 130a attached to the frame 115, and a plurality of louver pieces 130b provided on the louver connecting piece 130a. The louver connecting piece 130a and the louver pieces 130b are, for example, perpendicular to each other. The louver connecting piece 130a is attached to the side surface portion 111A. The louver pieces 130b are provided parallel to the X1 direction and the X2 direction perpendicular to the longitudinal direction of the luminaire 120, and a plurality of the louver pieces 130b are arranged so as to be aligned in the longitudinal direction (Y1 direction and Y2 direction) of the luminaire 120. The louver pieces 130b may be attached to the two louver connecting pieces 130a so that the angle with respect to the optical axis of the light source unit or the louver connecting piece 130a can be changed.

[0030] The lighting device 100 may have a form other than that shown in Fig. 1 and the like. For example, the lighting device 100 may have one or three or more luminaires 120 attached in a detachable manner. The lighting device 100 may not have the louver 130 attached, or may have other optical elements attached instead of the louver 130. The lighting device 100 may have the fixture body 110 equipped with only one frame body 115.

[0031] A space S is formed in the instrument body 110. The space S is formed between the two frame bodies 115 in the instrument body 110. That is, the space S is formed between the two frame bodies 111 in the instrument body 110. The space S is formed by being surrounded by the two side surface portions 111A and the two frames 112. The space S of the instrument body 110 penetrates in the up-down direction.

[0032] The space S may be formed in the fixture body 110, and may not necessarily be formed between the two frame bodies 115. For example, in the case where the lighting device 100 has only one frame body 115 formed in the fixture body 110, the space S may be formed alongside the frame body 115 in the horizontal direction. In the lighting system 10, a facility plate 200 for a system ceiling is disposed in the space S of the fixture body 110. The lighting device 100 has two elongated luminaires 120 disposed at an interval, and is configured so that the facility plate 200 can be attached between the two luminaires 120.

[0033] The lighting device 140 supplies power to the lamp 120 to light the lamp 120. The lighting device 140 is housed inside the frame 115. The lighting device 140 is attached to a top surface 111B of the frame 115. The lighting device 140 is disposed above the lamp 120, and the lower surface side of the lighting device 140 is covered by the lamp 120 disposed below.

[0034] [Facility Plate 200] FIG. 3 is a perspective view of the facility plate 200 according to the first embodiment. FIG. 4 is an exploded view of the facility plate 200 according to the first embodiment. FIG. 5 is a top view of the facility plate 200 according to the first embodiment. FIG. 6 is a right side view of the facility plate 200 according to the first embodiment. The left side of the facility plate 200 according to the first embodiment is the same as the right side shown in FIG. 6, and therefore is not shown. FIG. 7 is a front view of the facility plate 200 according to the first embodiment. The back of the facility plate 200 according to the first embodiment is the same as the front shown in FIG. 7, and therefore is not shown. In addition, in FIG. 5 to FIG. 7, the fall prevention wire 230 is not shown. The facility plate 200 will be described with reference to FIG. 1 and FIG. 3 to FIG. 7.

[0035] The facility plate 200 is a member for attaching the facility equipment 400 to a system ceiling. The facility plate 200 is, for example, a plate-shaped member attached to a ceiling such as a system ceiling. The facility plate 200 is formed in an elongated shape along the Y-axis direction. The facility plate 200 is a tray-shaped member on which the facility equipment 400 is installed. The facility equipment 400 is, for example, equipment necessary to achieve a certain purpose in the lighting space, such as an emergency light, a sprinkler, a speaker, a sensor, and a camera.

[0036] The facility plate 200 is attached to, for example, the lighting device 100. Note that the facility plate 200 is not limited to a plate attached to the lighting device 100, and may be attached to the bar member 300 via another attachment method.

[0037] The facility plate 200 includes one plate body 210 and a plurality of installation bases 220 attached to the plate body 210. The facility plate 200 preferably includes a fall prevention wire 230 for preventing the facility plate 200 from falling from a ceiling. Note that the fall prevention wire 230 is not an essential component of the facility plate 200, and the facility plate 200 does not necessarily have to include the fall prevention wire 230. In addition, the facility plate 200 may include a component other than the fall prevention wire 230 for preventing the facility plate 200 from falling.

[0038] The equipment 400 is disposed on the plate body 210. The plate body 210 is configured in a box shape with an open upper surface. That is, the plate body 210 is formed in a tray shape. The plate body 210 is configured, for example, by bending a metal plate material. The thickness dimension of the plate material constituting the plate body 210 is approximately 5 mm or less. The mass of the equipment plate 200 and the lighting system 10 including the plate body 210 can be reduced by reducing the thickness dimension of the plate body 210.

[0039] The plate body 210 may include a material other than metal. The plate body 210 may use a material other than a plate material. The plate body 210 may include a resin material, a ceramic material, or the like, in whole or in part. The plate body 210 is not limited to being manufactured by bending a metal plate, and may be manufactured using other methods such as extrusion molding or three-dimensional modeling.

[0040] The plate body 210 has a main body part 211 that is rectangular in plan view, and a main body side part 212 that is provided so as to rise from the periphery of the main body part 211. More specifically, the main body part 211 is formed in a rectangular plate shape in plan view, and has at least one equipment installation part 215 composed of at least one through hole in a portion where the equipment 400 is arranged. In addition, the main body side part 212 is composed of a plurality of side walls that are provided so as to extend upward along the periphery of the main body part 211.

[0041] The main body part 211 is formed in a rectangular plate shape in a plan view, and is configured in an elongated shape along the Y-axis direction, for example, as shown in Figures 4 and 5. One surface of the main body part 211, which is the front surface, is the design surface. On the other surface of the main body part 211, which is the back surface and is opposite to the design surface, the installation base 220 and at least a part of the facility equipment 400 are arranged.

[0042] The main body 211 is provided with an equipment installation section 215 corresponding to the equipment 400. The equipment installation section 215 is provided on an equipment plate 200 on which the equipment 400 is installed. The equipment plate 200 has the equipment installation section 215 formed between two adjacent installation bases 220 in the longitudinal direction (Y-axis direction) of the equipment plate 200. The equipment plate 200 has the equipment 400 disposed in the equipment installation section 215 between two adjacent installation bases 220 in the longitudinal direction (Y-axis direction) of the equipment plate 200. The equipment 400 is attached to the equipment installation section 215 from, for example, the front surface (lower surface) side, which is the design surface of the equipment plate 200.

[0043] The facility equipment installation section 215 is configured with at least one through hole. The facility equipment installation section 215 may be configured with one through hole or may be configured with multiple through holes. The facility equipment installation section 215 is used when installing the facility equipment 400, or is used as a part that allows the facility equipment 400 to perform its function. The facility equipment installation section 215 configured with one or more through holes may be formed in a manufacturing process of the facility plate 200, or may be additionally formed in a process of installing the facility equipment 400 to the lighting device 100.

[0044] The through-holes constituting the facility equipment installation section 215 are formed in a circular shape in a top view (plan view) as shown in Fig. 5. Note that the through-holes constituting the facility equipment installation section 215 are not limited to being formed in a circular shape in a plan view, and may be formed in other shapes, such as a polygonal shape in a plan view.

[0045] The body side portions 212 are provided along the periphery of the main body portion 211. The body side portions 212 are provided so as to extend upward from the periphery of the main body portion 211. The body side portions 212 form the side walls of the plate body 210.

[0046] The plate body 210 is formed in an elongated shape. The multiple body sides 212 have a pair of body long sides 212a constituting the long sides of the plate body 210 and a pair of body short sides 212b constituting the short sides of the plate body 210.

[0047] More specifically, the main body side portions 212 have a pair of main body long side portions 212a provided so as to rise along the long sides of the main body portion 211, and a pair of main body short side portions 212b provided so as to rise along the short sides of the main body portion 211. The main body long side portions 212a are formed along the longitudinal direction of the main body portion 211, and the main body short side portions 212b are formed along the lateral direction of the main body portion 211.

[0048] In the facility plate 200 of the first embodiment shown in Fig. 3 and Fig. 5, the two installation bases 220 are fixed to the main body long side parts 212a. Since the main body long side parts 212a are not external design parts visible from the lighting space side, the design of the facility plate 200 is not impaired even if the main body long side parts 212a are used to fix the installation bases 220. The fall prevention wires 230 are attached to the main body short side parts 212b, for example. The pair of fall prevention wires 230 are provided so as to be positioned approximately diagonally on the facility plate 200.

[0049] The longitudinal dimension of the main body long side portion 212a is preferably equal to or smaller than the longitudinal dimension of the main body portion 211. In the longitudinal direction of the elongated equipment plate 200, the dimension of the main body long side portion 212a is preferably equal to or smaller than the dimension of the main body portion 211. In addition, the transverse dimension of the main body short side portion 212b is preferably equal to or smaller than the transverse dimension of the main body portion 211. In the transverse direction of the elongated equipment plate 200, the dimension of the main body short side portion 212b is preferably equal to or smaller than the dimension of the main body portion 211.

[0050] The equipment plate 200 includes, for example, a set of two installation bases 220. In the equipment plate 200 of the first embodiment shown in FIG. 3, an example in which two installation bases 220 are used is shown, but the equipment plate 200 may use three or more installation bases 220 corresponding to a plurality of equipment devices 400.

[0051] The installation base 220 is a mounting member to which the equipment 400 is attached. The installation base 220 is formed in a box shape with an opening on the bottom side, and is attached to the plate body 210. The installation base 220 is shaped like an upside-down tray. The installation base 220 is configured to be elongated along the X-axis direction. That is, the installation base 220 is formed to be elongated along the short side direction of the equipment plate 200. The installation base 220 is a member that replaces a fixing member for fixing equipment that has been conventionally used, and is a mounting part to which the equipment 400 that has been conventionally used can be attached.

[0052] The installation base 220 is configured to meet the specifications required for installing the equipment 400 that can be installed on a ceiling material such as a ceiling panel, and is configured with a thickness dimension that mimics the thickness of a ceiling material such as a ceiling panel.

[0053] Each of the multiple installation bases 220 is disposed so as to extend between a pair of main body side parts 212 located on opposing sides of the main body part 211, among the multiple main body side parts 212. Each of the multiple installation bases 220 is provided so as to span between a pair of main body side parts 212 located on opposing sides of the main body part 211, among the multiple main body side parts 212.

[0054] The installation base 220 can be attached to the plate body 210 at a plurality of positions along the longitudinal direction of the equipment plate 200. That is, the installation position of the installation base 220 can be selected along the longitudinal direction of the plate body 210 in the equipment plate 200. Since the installation position of the equipment plate 200 can be selected along the longitudinal direction of the plate body 210 in the plate body 210, the equipment plate 200 can accommodate installation of equipment 400 with different specifications such as different dimensions.

[0055] Since the installation bases 220 can be attached to a plurality of locations along the longitudinal direction of the equipment plate 200, the arrangement area of ​​the equipment 400 can be freely determined within the range of the main body 211. The equipment plate 200 can change the attachment pitch of the two installation bases 220 by a similar function, so that the equipment plate 200 can accommodate equipment 400 with different dimensions and other specifications within the range of the main body 211. Although Figs. 3 to 5 show an example in which the equipment plate 200 uses two installation bases 220, the equipment plate 200 can have three or more installation bases 220 and attach two or more equipment 400.

[0056] The installation base 220 is formed by, for example, bending a metal plate. The thickness of the plate used for the installation base 220 is 5 mm or less. By reducing the thickness of the installation base 220, the lighting system 10 can reduce the mass of the facility plate 200 and the lighting device 100 including the installation base 220.

[0057] The installation base 220 may include a material other than metal. The installation base 220 may use a material other than a plate material. The installation base 220 may include a resin material, a ceramic material, or the like, in whole or in part. The installation base 220 is not limited to being manufactured by bending a metal plate, and may be manufactured using other methods such as extrusion molding or three-dimensional modeling. In this case, the installation base 220 is formed into a roughly rectangular parallelepiped shape.

[0058] The two installation bases 220 are configured with the same specifications in terms of shape, size, and material. Therefore, the two installation bases 220 can be managed as the same member. As described above, the number of installation bases 220 may be three or more. Therefore, each of the multiple installation bases 220 is configured with the same specifications in terms of shape, size, and material. Therefore, the multiple installation bases 220 can be managed as the same member.

[0059] The installation base 220 is configured in a generally box-like shape with an opening on the bottom side. The installation base 220 has a base main part 221 and a base side part 222 provided to rise from the periphery of the base main part 221. More specifically, each of the multiple installation bases 220 is formed in a rectangular plate shape smaller than the main body part 211 in a plan view, and has the base main part 221 to which the equipment 400 is attached. In addition, each of the multiple installation bases 220 has a multiple base side parts 222 that form side walls provided to extend downward along the periphery of the base main part 221.

[0060] The base main part 221 is formed in a rectangular plate shape smaller than the main body part 211 in a plan view, and is configured in an elongated shape along the X-axis direction, for example, as shown in Fig. 4 and Fig. 5. The longitudinal dimension of the base main part 221 is longer than the lateral dimension of the plate main body 210, as long as the attachment of the facility plate 200 to the lighting device 100 is not hindered.

[0061] The base side portion 222 is provided along the periphery of the base main portion 221. The base side portion 222 is provided so as to extend downward from the periphery of the base main portion 221. The base side portion 222 constitutes a side wall of the installation base 220.

[0062] Each of the installation bases 220 is formed in an elongated shape. The base sides 222 each have a pair of base long sides 222a constituting the long side portions of each of the installation bases 220, and a pair of base short sides 222b constituting the short side portions of each of the installation bases 220.

[0063] More specifically, the base side portion 222 has a pair of base long side portions 222a provided so as to rise along the long sides of the base main portion 221, and a pair of base short side portions 222b provided so as to rise along the short sides of the base main portion 221. The base long side portions 222a form end portions of the installation base 220 in the short direction, and the base short side portions 222b form end portions of the installation base 220 in the longitudinal direction.

[0064] In the longitudinal direction of the base main part 221, the dimension of the base long side part 222a is equal to or smaller than the dimension of the base main part 221. The dimension of the base long side part 222a in the longitudinal direction of the base main part 221 is equal to or smaller than the distance between the pair of main body short side parts 212b. The dimension of the base short side part 222b in the short direction of the base main part 221 is arbitrary as long as it does not prevent the base short side part 222b from being fixed to the main body long side part 212a. In addition, the dimension of the base short side part 222b in the up-down direction (Z-axis direction) is arbitrary as long as it does not prevent the base short side part 222b from being fixed to the main body long side part 212a.

[0065] The height dimension of the installation base 220 based on the back surface of the main body 211 is determined in accordance with the installation specifications based on the function of the facility equipment 400 to be attached to the facility plate 200. The height dimension of the installation base 220 is, for example, the distance between the back surface of the main body 211 and the upper surface of the base main part 221 in the vertical direction (Z-axis direction). The height dimension of the installation base 220 based on the back surface of the main body 211 is set in the range of, for example, 10 mm to 50 mm, taking into account the thickness dimension of a commonly used ceiling panel. In addition, considering that some facility equipment 400 specifies the range of the thickness dimension of the mounting part as 1 mm or more, it is preferable that the thickness dimension of the plate material used for the installation base 220 is 1 mm or more, or the sum of the thickness dimension of the plate material used for the installation base 220 and the thickness dimension of the plate material used for the plate main body 210 is 1 mm or more.

[0066] The base long side portion 222a is formed along the long direction of the base main portion 221, and the base short side portion 222b is formed along the short direction of the base main portion 221. The base long side portion 222a is arranged along the short direction of the plate body 210, and the base short side portion 222b is arranged along the long direction of the plate body 210. In other words, the base long side portion 222a is arranged along the main body short side portion 212b of the plate body 210, and the base short side portion 222b is arranged along the main body long side portion 212a of the plate body 210.

[0067] The pair of base short side portions 222b are disposed in the X-axis direction so as to face the main body long side portions 212a of the plate main body 210. The pair of base short side portions 222b are disposed outside the main body long side portions 212a in the X-axis direction.

[0068] Each of the installation bases 220 is disposed on both sides of the facility equipment installation section 215, and at least one of the multiple base side sections 222 and at least one of the multiple main body side sections 212 are fixed to each of the multiple installation bases 220. More specifically, each of the multiple installation bases 220 is fixed to at least one of the pair of base short side sections 222b and at least one of the pair of main body long side sections 212a.

[0069] In the facility plate 200 according to the first embodiment, the base short sides 222b, which are the ends of the two installation bases 220 arranged on the outer sides of the main body long sides 212a, are fixed to the main body long sides 212a so as not to impair the design of the facility plate 200. The base short sides 222b of the installation bases 220 are fixed to the main body long sides 212a by a method such as screw fixing, riveting fixing, caulking fixing, welding fixing, adhesive fixing, or latching fixing.

[0070] By fixing the installation base 220 to the main body longitudinal side portion 212a of the plate main body 210, the overall rigidity of the equipment plate 200 is improved, and the shape stability is improved. That is, the equipment plate 200 can suppress deformation of the equipment plate 200 caused by its own weight or by the installation of the equipment 400. Therefore, the equipment plate 200 can maintain the correct installation posture of the equipment 400 installed on the equipment plate 200 for a long period of time. In addition, the equipment plate 200 can suppress deformation caused by vibrations and impacts during transportation or the influence of the storage posture.

[0071] The equipment 400 is disposed on the plate body 210 of the equipment plate 200. The equipment 400 is disposed on the equipment installation section 215 of the equipment plate 200. The equipment 400 is disposed on the equipment plate 200 in a state where it is inserted into a through hole of the equipment installation section 215 provided on the main body 211, for example.

[0072] The facility plate 200 is arranged with the facility equipment 400 inserted from the lighting space side into a through hole of the facility equipment installation section 215 provided in the main body 211, and the facility equipment 400 is engaged with the installation base 220 via an engagement section 405 such as a spring. The facility equipment 400 has an engagement section 405 such as a spring, and is attached from the front surface (lower surface) side, which is the design surface of the facility plate 200. At this time, the installation base 220 functions as an engaged section that is an engagement target of the engagement section 405 such as a spring. In other words, the installation base 220 functions as an engaged section that is an engagement target of the facility equipment 400.

[0073] Alternatively, the equipment plate 200 can arrange the equipment 400 on the upper surface side of the equipment plate 200 using the installation base 220. For example, the equipment plate 200 has the equipment 400 such as a speaker arranged above a plurality of through holes of the equipment installation section 215 provided in the main body 211, and the equipment 400 is engaged with the installation base 220. That is, the equipment 400 is arranged on the back surface side of the equipment plate 200 above the through holes of the equipment installation section 215 provided in the main body 211.

[0074] The equipment 400 is installed on the equipment plate 200 from the back surface (upper surface) side, which is the non-design surface of the main body 211, and is fixed to the installation base 220 by using a method such as screw fixing, rivet fixing, welding fixing, adhesive fixing, or locking fixing. In this case, the installation base 220 functions as an object to be fastened with a screw or the like, or as a base on which the equipment 400 is placed. The installation base 220 may be provided on an equipment plate 200 on which the equipment 400 is not placed.

[0075] The two or a set of installation bases 220 are disposed on the back surface (upper surface) which is the non-design surface opposite to the front surface (lower surface) which is the design surface of the plate body 210. As described above, in the installation base 220 of the first embodiment, the base short side portions 222b which are the ends of the two installation bases 220 are fixed to the main body long side portions 212a so as not to impair the design of the equipment plate 200.

[0076] 4, the plate body 210 may be provided with a plurality of guides 213 for specifying positions at which the plurality of installation bases 220 are to be arranged. In order to position the installation bases 220 when the installation bases 220 are fixed to the body longitudinal side parts 212a of the plate body 210, the body longitudinal side parts 212a may be provided with a plurality of positioning guides 213 for specifying positions at which the installation bases 220 are to be arranged.

[0077] Even if the guide 213 is provided on the main body longitudinal side portion 212a of the facility plate 200 that is not disposed in the exterior design portion in the use state, it does not affect the design of the facility plate 200. Note that the guide 213 may be attached to the back surface (upper surface) of the plate main body 210 as shown in FIG. 4, if the guide 213 is provided in a manner that does not affect the design.

[0078] Each of the multiple guides 213 may simply indicate a position, or may have a function of temporarily holding the installation base 220. The guides 213 can be attached to the plate body 210 by using a method such as printing, painting, engraving, etc. The guides 213 having the function of temporarily holding the installation base 220 are formed, for example, in a convex or concave shape. The guides 213 may have a function of temporarily holding the installation base 220 by forming the guides 213 by performing processing such as cutting and raising, cutting and squeezing, and squeezing on the main body longitudinal side parts 212a or the main body main part 211.

[0079] Fig. 8 is a perspective view of the facility plate 200 according to the embodiment 1. Fig. 9 is a top view of the facility plate 200 according to the embodiment 1. The configuration of the installation base 220 will be further described with reference to Figs. 8 and 9.

[0080] At least one of the multiple installation bases 220 may have an equipment rotation prevention portion 225 formed in a recessed shape at a corner portion between the base main portion 221 and at least one of the multiple base side portions 222. The equipment rotation prevention portion 225 is a notch portion provided in the installation base 220, and is a portion where a part of the equipment 400 or a member for fixing the equipment 400 is disposed.

[0081] The installation base 220 may include at least one equipment rotation prevention portion 225 which is a cutout portion formed by cutting out a corner portion between the base main portion 221 and at least one of the multiple base side portions 222. The equipment rotation prevention portion 225 is formed at a corner portion between the base longitudinal side portion 222a and the base main portion 221. The equipment rotation prevention portion 225 is formed along the longitudinal direction of the base longitudinal side portion 222a and the base main portion 221. The equipment rotation prevention portion 225 is formed so as to be recessed inward of the installation base 220.

[0082] 8 and 9, in the facility plate 200 according to the first embodiment, the two installation bases 220 each include two cutout portions that are the facility equipment rotation prevention portions 225. Note that the installation base 220 only needs to include at least one facility equipment rotation prevention portion 225, and may include a plurality of facility equipment rotation prevention portions 225.

[0083] As described above, the equipment plate 200 may be arranged by inserting the equipment 400 into the through-hole of the equipment installation section 215 provided in the main body 211 from the lighting space side. In such a case, the equipment 400 is arranged by engaging with the installation base 220 using an engagement section 405 such as a spring. The equipment plate 200 can prevent the equipment 400 from rotating by engaging the engagement section 405 such as a spring with the equipment rotation prevention section 225.

[0084] In addition, when the equipment 400 is fixed to the installation base 220 from the back (top) side of the main body 211, the equipment plate 200 can prevent the equipment 400 from rotating by providing the equipment 400 with an engagement portion 405 that engages with the equipment rotation prevention portion 225.

[0085] The facility equipment rotation prevention portion 225, which is a cutout portion, is preferably provided in the installation base 220 so as to accommodate the installation of facility equipment 400 having different specifications such as size or dimensions. In this case, it is preferable to provide an identification mark on the installation base 220 so that a worker such as a construction worker can understand the purpose of the facility equipment rotation prevention portion 225 and the facility equipment 400 that corresponds to the facility equipment rotation prevention portion 225.

[0086] The identification mark can be provided by a method such as printing, painting, engraving, etc. Even if the installation base 220 has the equipment rotation prevention portion 225, the installation base 220 is not disposed on the exterior portion such as the design surface of the equipment plate 200, and therefore does not affect the design of the equipment plate 200. Note that the identification mark may be provided on the back surface (upper surface) of the plate body 210, if the identification mark is provided by a method that does not affect the design.

[0087] The installation base 220 may include at least one screw hole 226. For example, in the facility plate 200 according to the first embodiment, as shown in Fig. 8 and Fig. 9, each of the two installation bases 220 includes seven screw holes 226. The number of screw holes 226 may be one or more. At least one screw hole 226 for fixing the facility device 400 is formed in the base main part 221 of the installation base 220.

[0088] The screw holes 226 are used for installing the equipment 400. The equipment 400 may be fixed to the installation base 220 directly by fastening a fixing member such as a screw into the screw holes 226, or may be fixed to the installation base 220 indirectly via another fixing member.

[0089] The screw holes 226 are preferably provided in the installation base 220 to accommodate installation of equipment 400 having different specifications such as sizes or dimensions. In this case, it is preferable to provide an identification mark on the installation base 220 so that a user such as a construction worker can understand the purpose of the screw holes 226 and the equipment 400 that corresponds to the screw holes 226.

[0090] The identification mark can be provided by a method such as printing, painting, engraving, etc. Even if the installation base 220 has the screw holes 226, the installation base 220 is not disposed on the exterior portion of the facility plate 200, and therefore does not affect the design of the facility plate 200. The identification mark may be provided on the upper surface (rear surface) of the plate body 210 by a method that does not affect the design.

[0091] [Functions and Effects of the Equipment Plate 200 and the Lighting System 10] The facility plate 200 is formed in a box shape with an open bottom side, and includes a plurality of installation bases 220 attached to the plate body 210. Each of the plurality of installation bases 220 is disposed so as to extend between a pair of main body side parts 212 located on opposing sides of the main body part 211, among the plurality of main body side parts 212. Each of the plurality of installation bases 220 is disposed on both sides of the facility equipment installation part 215, and at least one of the plurality of base side parts 222 and at least one of the plurality of main body side parts 212 are fixed to each other.

[0092] The equipment plate 200 can accommodate installation of equipment 400 of different dimensions by fixing a plurality of installation bases 220 of the same structure to the main body side 212 by changing the distance from the equipment installation section 215. Therefore, the equipment plate 200 does not need to design, manufacture, and manage the installation base 220, which is a fixing member, for each equipment 400 of different dimensions. In addition, the equipment plate 200 is efficient and does not require much effort to assemble because the fixing position of the installation base 220 is simply changed for each equipment 400 of different dimensions. Installation bases 220 of the same specifications (shape, size, material) can be managed as the same member. The equipment plate 200 can provide an equipment plate that can accommodate installation of a wide variety of equipment 400 by using a plurality of installation bases 220 of the same specifications.

[0093] Conventional equipment plates require the preparation of fixing members with different specifications (dimensions) in accordance with the dimensions of the equipment. When fixing members with different specifications (dimensions) are prepared in accordance with the dimensions of the equipment, the equipment plate becomes an obstacle to reducing costs such as material costs, manufacturing costs, management costs, and assembly costs of the fixing members. In contrast, the equipment plate 200 uses the installation base 220 with the same specifications (dimensions), and does not require the preparation of fixing members with different specifications (dimensions). Therefore, the equipment plate 200 can reduce costs such as material costs, manufacturing costs, management costs, and assembly costs, compared to the case where fixing members with different specifications (dimensions) are prepared.

[0094] In addition, each of the installation bases 220 is fixed to at least one of the pair of base short side parts 222b and at least one of the pair of main body long side parts 212a. The equipment plate 200 improves the rigidity of the entire equipment plate 200 and improves the shape stability by fixing the installation bases 220 to the main body long side parts 212a of the plate main body 210. That is, the equipment plate 200 can suppress deformation of the equipment plate 200 due to its own weight or the installation of the equipment 400. Therefore, the equipment 400 installed on the equipment plate 200 can maintain the correct installation posture for a long period of time. In addition, the above configuration of the equipment plate 200 can suppress deformation due to vibrations and impacts during transportation or the influence of the storage posture.

[0095] Furthermore, at least one screw hole 226 for fixing the equipment 400 is formed in the base main part 221. Since the screw hole 226 is formed in the base main part 221 of the equipment plate 200, the equipment 400 can be positioned more easily and the equipment 400 can be attached more easily than when the screw hole 226 is not provided. The fixing of the equipment 400 using the screw hole 226 will be described later in the embodiment. The equipment 400 may be directly attached to the installation base 220 or indirectly attached using an auxiliary member or the like.

[0096] Furthermore, the plate body 210 may be provided with a plurality of guides 213 for identifying positions for arranging the plurality of installation bases 220. Since the equipment plate 200 has the plurality of guides 213, the equipment plate 200 can more easily position the installation bases 220 than when the equipment plate 200 does not have the plurality of guides 213, and the assembly can be more efficient.

[0097] At least one of the installation bases 220 has an equipment rotation prevention part 225 where a part of the equipment 400 or a member for fixing the equipment is disposed at a corner between the base main part 221 and at least one of the base side parts 222. The equipment plate 200 can prevent the equipment 400 from rotating by engaging the part of the equipment 400 or a spring or the like for fixing the equipment 400 with the equipment rotation prevention part 225.

[0098] Furthermore, since the lighting system 10 includes the facility plate 200, the lighting system 10 can achieve the same effect as the facility plate 200.

[0099] Embodiment 2 Fig. 10 is a perspective view of the facility plate 200 according to the second embodiment. Fig. 11 is a plan view of the facility plate 200 according to the second embodiment. The facility plate 200 according to the second embodiment will be described with reference to Figs. 10 and 11. The facility plate 200 according to the second embodiment is similar to the facility plate 200 according to the first embodiment in configurations other than those described below. Components having the same functions and actions as those in the first embodiment are denoted by the same reference numerals and description thereof will be omitted.

[0100] The facility plate 200 according to the second embodiment does not have the facility equipment rotation prevention portion 225 and the screw hole 226, which are cutout portions, in the installation base 220. As shown in Fig. 10 and Fig. 11, the facility plate 200 does not necessarily have to have the facility equipment rotation prevention portion 225 and the screw hole 226. In the facility plate 200 according to the second embodiment, the base main portion 221 of the installation base 220 is formed in a flat plate shape without holes or irregularities.

[0101] The facility equipment 400 may be engaged with the installation base 220 using an engagement portion 405 such as a spring, or fixed to the installation base 220 using a fixing member such as a screw, or may be fixed to the installation base 220 using a magnetic force or an adhesive member. If such a method is used, processing such as the facility equipment rotation prevention portion 225 and the screw hole 226 on the installation base 220 is not required.

[0102] [Functions and Effects of the Equipment Plate 200 and the Lighting System 10] The base main part 221 of the facility plate 200 according to the second embodiment is formed in a flat plate shape without holes or unevenness. The facility equipment 400 may be engaged with the installation base 220 using a spring or the like, or may be fixed to the installation base 220 using a fixing member such as a screw, or may be fixed to the installation base 220 using a magnetic force or an adhesive member. If such a method is used, the installation base 220 does not require processing such as the facility equipment rotation prevention part 225 and the screw hole 226, and manufacturing costs can be reduced compared to the case where the facility equipment rotation prevention part 225 and the screw hole 226 are formed.

[0103] Furthermore, since the lighting system 10 includes the facility plate 200, the lighting system 10 can achieve the same effect as the facility plate 200.

[0104] Moreover, the facility plate 200 according to the second embodiment can exert the same effects as those of the facility plate 200 according to the first embodiment in the parts having the same configurations.

[0105] Embodiment 3 Fig. 12 is a perspective view of the facility plate 200 according to the third embodiment. The facility plate 200 according to the third embodiment will be described with reference to Fig. 12. The facility plate 200 according to the third embodiment is similar to the facility plate 200 according to the first or second embodiment in configurations other than those described below. Components having the same functions and actions as those in the first and second embodiments are denoted by the same reference numerals and will not be described.

[0106] As shown in Fig. 12, the equipment plate 200 may include three or more installation bases 220 in order to install a plurality of equipment devices 400 having different specifications such as shapes, sizes, or functions. The equipment plate 200 has an equipment installation section 215 formed between two adjacent installation bases 220 in the longitudinal direction (Y-axis direction) of the equipment plate 200. The plurality of installation bases 220 are three or more installation bases 220, and the equipment installation section 215 is provided in a portion between the adjacent installation bases 220 among the plurality of installation bases 220. The equipment plate 200 has the equipment devices 400 arranged in the equipment installation section 215 between the two adjacent installation bases 220 in the longitudinal direction (Y-axis direction) of the equipment plate 200.

[0107] As shown in Fig. 12, the facility plate 200 supports different mounting methods for the facility equipment 400. The facility equipment 400 has an engagement portion 405 such as a spring, and is mounted to the installation base 220 from the front surface (lower surface) side, which is the design surface, of the facility plate 200. Alternatively, the facility equipment 400 is fixed to the installation base 220 using a fastener 406 from the back surface (upper surface), which is the non-design surface.

[0108] [Functions and Effects of the Equipment Plate 200 and the Lighting System 10] The plurality of installation bases 220 are three or more installation bases 220, and the equipment installation section 215 is provided in a portion between adjacent installation bases 220 among the plurality of installation bases 220. With the above-mentioned configuration, the equipment plate 200 can accommodate a plurality of equipment 400.

[0109] Furthermore, since the lighting system 10 includes the facility plate 200, the lighting system 10 can achieve the same effect as the facility plate 200.

[0110] Moreover, the facility plate 200 according to the third embodiment can exert the same effects as those of the facility plate 200 according to the first or second embodiment in the portions having the same configurations.
