DETAILED DESCRIPTION OF THE INVENTION

[0024] [Example 1] A first example of an embodiment of the present disclosure will be described with reference to FIGS.

[0025] In this example, a case will be described in which a lighting fixture is attached to a louver unit, which is an example of a decorative material unit, using a lighting fixture attachment according to one aspect of the present disclosure.

[0026] However, the lighting fixture mounting fixture according to one aspect of the present disclosure is not limited to louver units, but can be used to mount lighting fixtures on decorative material units other than louver units, such as decorative panel units and punched metal units.

[0027] FIG. 1 shows an example of an exterior wall of a building 3, in which a plurality of louver units 2 are fixed to the exterior side of a curtain wall 1.

[0028] In the following explanation, the left-right direction and the up-down direction refer to the respective directions when the curtain wall 1, which is a wall component, is viewed from the front. Furthermore, the out-of-plane direction refers to the depth direction (projection direction) when the curtain wall 1 is viewed from the front, and the outdoor side in the out-of-plane direction is simply referred to as the "outdoor side," and the indoor side in the out-of-plane direction is simply referred to as the "indoor side." Below, we will provide an overview of the components of the curtain wall 1 and the louver unit 2, and then provide a detailed explanation of the structure of the louvers 10 and stringers 11a, 11b that make up the louver unit 2, as well as the structure of the lighting fixture mounting bracket 16.

[0029] The curtain wall 1 forms the exterior wall of the building 3 .

[0030] The curtain wall 1 of this example is a mullion-type curtain wall, and includes a plurality of mullions 4, a plurality of mullions 5a, 5b, a plurality of glass panels 6, and a plurality of spandrel panels 7.

[0031] The mullions 4 are arranged with their longitudinal axes facing up and down and are fixed to the outdoor side of the main body 9 via mounting brackets 8. The transoms 5a, 5b are arranged with their longitudinal axes facing left and right and are connected to span between adjacent mullions 4 in the left and right direction. The glass panels 6 are installed in openings surrounded on all four sides by the mullions 4 and the transoms 5a, 5b and form the window section of the building 3. The spandrel panels 7 are installed in openings surrounded on all four sides by the mullions 4 and the transoms 5a, 5b and form the wall section of the building 3.

[0032] In the building 3 of this example, the glass panels 6 and spandrel panels 7 are arranged continuously in the left-right direction, sandwiching the mullions 4 between them, and the glass panels 6 and spandrel panels 7 are arranged alternately in the up-down direction, sandwiching the lattice panels 5a and 5b between them.

[0033] The louver unit 2 is fixed to the exterior side of the curtain wall 1 as described above, and forms the exterior wall of the building 3.

[0034] The louver unit 2 has a plurality of louvers 10, which are decorative materials, and a plurality of stringers 11a, 11b, which are fixing brackets. The louver unit 2 is configured by connecting a plurality of louvers 10, each arranged with its longitudinal direction facing up and down, with a plurality of stringers 11a, 11b, each arranged with its longitudinal direction facing left and right. In the example shown in FIG. 9, the louver unit 2 is configured by connecting eight louvers 10 with two stringers 11a, 11b. The louvers 10 are fixed to the stringers 11a, 11b with first connecting members 12.

[0035] The multiple louvers 10 that make up the louver unit 2 are arranged parallel to each other and at equal intervals in the left-right direction. The multiple stringers 11a, 11b that make up the louver unit 2 are arranged parallel to each other and spaced apart in the up-down direction.

[0036] The louver units 2 are arranged continuously in the vertical and / or horizontal directions on the outdoor side of the curtain wall 1, arranged at intervals in the vertical and / or horizontal directions, or arranged randomly, to give design characteristics to the exterior wall of the building 3.

[0037] The number of louvers and stringers that make up a louver unit can be changed as appropriate depending on the installation position of the louver unit, etc. Furthermore, the vertical positions of the stringers that make up the louver unit can also be changed as appropriate depending on the installation position of the louver unit, etc.

[0038] The louver unit 2 is fixed to the curtain wall 1 by fixing both left and right ends of the stringers 11a, 11b to brackets 14 with second connecting members 13. The brackets 14 are fixed to the mullions 4 of the curtain wall 1 with third connecting members 15.

[0039] A lighting fixture 17 is attached to the louver unit 2 using a lighting fixture mounting bracket 16. This lights up the exterior wall of the building 3, improving the design of the exterior wall of the building 3 at night.

[0040] The louver unit 2 is pre-assembled in a factory and transported to the construction site of the building 3. The louver unit 2 is then lifted using a crane or the like and fixed to the brackets 14 that have been pre-fixed to the mullions 4 in the factory.

[0041] The following describes the structure of the louver 10 and stringers 11a and 11b, as well as the structure of the lighting fixture mounting bracket 16. However, the following description is an example of an embodiment, and can be modified as desired within the scope of the effects of the invention.

[0042] The louver 10 is made of an extruded aluminum alloy material and has a generally rectangular cylindrical shape.

[0043] In this example, the louver 10 further has an indoor side wall portion 18 facing the curtain wall 1, a storage portion 19, and an insertion portion 20 that penetrates the indoor side wall portion 18 and communicates with the storage portion 19.

[0044] The storage section 19 is provided in the left-right center of the indoor end of the louver 10. The storage section 19 is a space with a rectangular cross section, and stores the head 22 of the bolt 21 that constitutes the first connecting member 12. The storage section 19 can store the head 22 of the bolt 21 so that it cannot rotate relative to the bolt 21. The head 22 of the bolt 21 is configured in the shape of a rectangular plate.

[0045] The storage sections 19 are open on both vertical end faces of the louver 10. The storage sections 19 are provided over the entire length of the louver 10.

[0046] The insertion section 20 penetrates the indoor side wall section 18 in the out-of-plane direction and communicates with the storage section 19. The insertion section 20 is configured as a long slit in the longitudinal direction of the louver 10, and opens at both end faces in the vertical direction of the louver 10 and at the center in the horizontal direction of the indoor side surface. The insertion section 20 is provided along the entire length of the louver 10.

[0047] The width dimension in the left-right direction of the insertion portion 20 is larger than the diameter of the shaft portion 23 of the bolt 21 that constitutes the first connecting member 12 and smaller than the left-right dimension of the head portion 22 of the bolt 21.

[0048] Both upper and lower end faces of the louver 10 are covered by covers 24. The cover 24 fixed to the lower end face of the louver 10 has drainage holes 25 formed therein.

[0049] The stringers 11 a and 11 b correspond to fixing fittings and fix the louvers 10 to the curtain wall 1 .

[0050] The stringers 11a and 11b are long members made of extruded aluminum alloy material, and are arranged with their longitudinal directions oriented in the left-right direction.

[0051] The stringers 11a and 11b have an L-shaped plate configuration, and have an end face shape that is approximately L-shaped when viewed from the left and right. The stringers 11a and 11b include a vertical plate portion 26 and a horizontal plate portion 27.

[0052] The stringers 11a and 11b are arranged at positions overlapping the stringers 5a and 5b in the out-of-plane direction.

[0053] In this example, the stringers 11a and 11b are attached in opposite directions relative to the louver 10, depending on their attachment positions relative to the louver 10. That is, the stringer 11a, which is located on the outdoor side of the transom 5a that holds the upper edge of the glass panel 6, is attached to the louver 10 with the unconnected end of the vertical plate portion 26, one of the ends on both the upper and lower sides that is not connected to the horizontal plate portion 27, facing upward, whereas the stringer 11b, which is located on the outdoor side of the transom 5b that holds the lower edge of the glass panel 6, is attached to the louver 10 with the unconnected end of the vertical plate portion 26 facing downward. The stringers 11a and 11b differ only in their attachment directions and have the same configuration except for the presence or absence of a second through hole 28b, which will be described later.

[0054] The vertical plate portion 26 has a generally flat plate shape, is disposed with its plate thickness direction aligned with the out-of-plane direction, and is fixed to the indoor side wall portion 18 of the louver 10 by the first connecting member 12 .

[0055] The vertical plate portion 26 has a plurality of first through holes 28a through which the shafts 23 of the bolts 21 constituting the first connecting member 12 can be inserted. The vertical plate portion 26 has the same number of first through holes 28a as the number of louvers 10 constituting the louver unit 2. The multiple first through holes 28a are arranged spaced apart in the left-right direction at an equal pitch as the louvers 10 constituting the louver unit 2. The first through holes 28a are provided in the middle of the vertical plate portion 26.

[0056] The louver 10 and the vertical plate portion 26 are fastened together by accommodating the head 22 of the bolt 21 in the accommodating portion 19 of the louver 10, loosely fitting a washer 29 onto the shaft portion 23 that is inserted in the out-of-plane direction through the insertion portion 20 of the louver 10 and the first through-hole 28a of the vertical plate portion 26, and then screwing in a nut 30. Note that although the work of fixing the louver 10 to the stringers 11a and 11b can be performed at the construction site, it is preferable to perform this work in a factory to improve workability.

[0057] Of the stringers 11a and 11b, the stringer 11a, which is attached to the louver 10 with the non-connected end of the vertical plate portion 26 facing upward, has a second through hole 28b in addition to the first through hole 28a in the vertical plate portion 26. The second through hole 28b is positioned at a position offset from the first through hole 28a in the left-right direction and above the first through hole 28a.

[0058] In this example, the vertical plate portion 26 has a flat end face on the non-connection side that is not connected to the horizontal plate portion 27. That is, the upper end face of the vertical plate portion 26 that constitutes the stringer 11a and the lower end face of the vertical plate portion 26 that constitutes the stringer 11b are flat.

[0059] In this example, the vertical plate portion 26 has a protruding portion 31 at the end on the non-connecting side that protrudes toward the indoor side. The protruding portion 31 has a substantially trapezoidal cross-sectional shape. However, when implementing a decorative material fall prevention device according to one embodiment of the present disclosure, the protruding portion can be omitted. Furthermore, the cross-sectional shape of the protruding portion is not limited to a trapezoid, and other shapes, such as a hook shape, can be used.

[0060] The horizontal plate portion 27 has a flat plate shape and is disposed substantially horizontally with its thickness direction aligned with the vertical direction.

[0061] For stringer 11a, which is disposed on the outdoor side of transom 5a that holds the upper edge of glass panel 6, the outdoor side end of horizontal plate portion 27 is connected to the lower end of vertical plate portion 26. In contrast, for stringer 11b, which is disposed on the outdoor side of transom 5b that holds the lower edge of glass panel 6, the outdoor side end of horizontal plate portion 27 is connected to the upper end of vertical plate portion 26.

[0062] The horizontal plate portion 27 has both left and right end portions fixed to the bracket 14 by the second connecting members 13. Specifically, the both left and right end portions of the horizontal plate portion 27 are fixed to the bracket 14 using the second connecting members 13 arranged with their central axes oriented vertically.

[0063] The bracket 14 is fixed to the outdoor side of the mullion 4 using a third connecting member 15 arranged with its central axis facing out of the plane. The bracket 14 is made of stainless steel plate and comprises a vertical wall portion 32 fixed to the mullion 4 and a base plate portion 33 to which the horizontal plate portions 27 of the stringers 11a and 11b are fixed.

[0064] <Lighting fixture mounting bracket> The lighting fixture mounting fixture 16 is a dedicated member for mounting the lighting fixture 17 on the louver unit 2.

[0065] The lighting fixture fixture 16 is made of an extruded aluminum alloy and is constructed as a single unit. However, when implementing a lighting fixture fixture according to one embodiment of the present disclosure, the lighting fixture fixture may be constructed from other materials such as synthetic resin, or may be constructed by combining multiple parts.

[0066] In this example, one lighting fixture fixture 16 is attached to one louver unit 2. Specifically, the lighting fixture fixture 16 is attached to the indoor side of the vertical plate portion 26 of one stringer 11a, of the multiple stringers 11a, 11b that make up the louver unit 2, which is attached to the louver 10 with the non-connected end of the vertical plate portion 26 facing upward. However, when implementing a lighting fixture mounting bracket according to one aspect of the present disclosure, multiple lighting fixture fixtures can also be attached to one decorative material unit.

[0067] The lighting fixture fixture 16 is fixed to the stringer 11a using a plurality of fixing brackets 34. The structure of the fixing brackets 34 will be described later.

[0068] In this example, the lighting fixture attachment 16 is an elongated member, and is disposed with its longitudinal direction oriented in the left-right direction.

[0069] The width dimension in the left-right direction of the lighting fixture fixture 16 is smaller than the left-right dimension of the louver unit 2. In the example shown, the width dimension in the left-right direction of the lighting fixture fixture 16 is slightly smaller than the length dimension in the left-right direction of the stringer 11a.

[0070] The vertical dimension of the lighting fixture fixture 16 is slightly smaller than the vertical dimension of the stringer 11a. In the illustrated example, the vertical dimension of the lighting fixture fixture 16 is approximately the same as the vertical dimension from the top surface of the horizontal plate portion 27 that constitutes the stringer 11a to the top end surface of the vertical plate portion 26.

[0071] The out-of-plane dimension of the lighting fixture fixture 16 is sufficiently smaller than the out-of-plane dimension of the stringer 11a. In the illustrated example, the out-of-plane dimension of the lighting fixture fixture 16 is equal to or less than half the out-of-plane dimension from the indoor side of the vertical plate portion 26 constituting the stringer 11a to the indoor-side end face of the horizontal plate portion 27.

[0072] The lighting fixture fixture 16 is covered from the outdoor side by the vertical plate portion 26 of the stringer 11a and is covered from below by the horizontal plate portion 27 of the stringer 11a, so it is difficult to see from the outdoor side.

[0073] The lighting fixture fixture 16 has a housing frame 35 and a cover plate 36 .

[0074] The storage frame 35 is provided in the upper part of the lighting fixture fixture 16, and the cover plate 36 is provided in the lower part of the lighting fixture fixture 16. In this example, the storage frame 35 and the cover plate 36 are integrally formed. However, the storage frame and the cover plate, which are formed separately from each other, can also be fixed together by welding, caulking, or the like.

[0075] The housing frame 35 is disposed on the indoor side of the upper portion of the vertical plate portion 26 that constitutes the stringer 11a, and above the indoor side end of the bolt 21 and nut 30 that constitute the first connecting member 12. The cover plate 36 is disposed between the indoor side end face of the bolt 21 (shank 23) that constitutes the first connecting member 12 and the upper end of the bolt 37 and nut 38 that constitute the second connecting member 13 in the out-of-plane direction.

[0076] The housing frame 35 has therein a housing space 40 capable of housing the light source 39 of the lighting fixture 17, and an opening 41 through which light from the light source 39 passes.

[0077] The cover plate 36 extends downward from the housing frame 35, and its lower end abuts or closely faces the stringer 11a. In this example, the cover plate 36 has its lower end abutted against the upper surface of the horizontal plate portion 27 that constitutes the stringer 11a.

[0078] A wiring space 43 for accommodating wiring 42 of the lighting fixture 17 is formed in the area surrounded by the lower surface of the housing frame 35, the side surface of the cover plate 36, and the stringer 11a. Specifically, the wiring space 43 is formed in the area surrounded on all four sides by the lower surface of the housing frame 35, the outdoor-facing side surface of the cover plate 36, the indoor-facing side surface of the vertical plate portion 26, and the upper surface of the horizontal plate portion 27. The wiring space 43 accommodates wiring 42 drawn from the light source 39 that constitutes the lighting fixture 17.

[0079] In this example, an LED module is accommodated in the accommodation space 40 of the accommodation frame 35 as the light source 39. However, when implementing a lighting fixture fixture according to one aspect of the present disclosure, the light source of the lighting fixture accommodated in the accommodation space is not limited to an LED module, and may be a fluorescent lamp, a light bulb, or the like.

[0080] In this example, an LED module serving as a light source 39 is housed in the housing space 40 of the housing frame 35 while being held by a holding bracket 44. The holding bracket 44 serves to stabilize the posture of the light source 39 and to adjust the height of the light source 39 in the housing space 40. In this example, one light source 39 is held by a plurality of holding brackets 44 arranged at intervals in the left-right direction.

[0081] The holding bracket 44 has a substantially H-shaped cross section and is composed of a pair of side plates 45a, 45b that are spaced apart in the out-of-plane direction and arranged substantially parallel to each other, and a connecting plate 46 that connects the pair of side plates 45a, 45b at their vertically middle portions in the out-of-plane direction.

[0082] The light source 39 is placed on the connecting plate 46 and is accommodated in the accommodation space 40 of the accommodation frame 35 in a state where it is disposed between the upper portions of the pair of side plates 45a, 45b. The upper ends of the side plates 45a, 45b are provided with barbs that can engage with the upper end surfaces of the light source 39.

[0083] The size and shape of the housing frame 35 are determined according to the size and shape of the light source 39 of the lighting fixture 17 to be housed in the housing space 40. In this example, the size and shape of the housing frame 35 are determined according to the size and shape of the holding bracket 44 so that the holding bracket 44 can be housed in the housing space 40 without rattle.

[0084] In this example, the storage frame 35 has a substantially U-shaped cross section. Therefore, the storage space 40 has a substantially rectangular cross section. However, when implementing a lighting fixture mount according to one aspect of the present disclosure, the cross section of the storage frame is not limited to a substantially U-shaped cross section, and other shapes such as a substantially U-shaped cross section, a substantially C-shaped cross section, or a substantially V-shaped cross section may be adopted.

[0085] In this example, the opening 41 of the storage frame 35 faces upward. However, the opening of the storage frame is not limited to facing upward, and may face in a direction other than upward, such as toward the indoor side or the outdoor side.

[0086] The housing frame 35 has a bottom plate portion 47 and a pair of side plate portions 48a, 48b.

[0087] The bottom plate portion 47 has a flat plate shape and is disposed substantially horizontally with its thickness direction aligned with the vertical direction. Therefore, the bottom plate portion 47 is disposed substantially parallel to the horizontal plate portions 27 that constitute the stringer 11a. The lower surface of the storage frame 35 is formed by the lower surface of the bottom plate portion 47.

[0088] The bottom plate portion 47 has a communication portion 49 that connects the storage space 40 and the wiring space 43. In this example, the bottom plate portion 47 has multiple communication portions 49. Specifically, the bottom plate portion 47 has one communication portion 49 at each of its left and right ends. The communication portions 49 are configured as notches. However, when implementing a lighting fixture attachment according to one aspect of the present disclosure, the communication portions are not limited to notches and can be configured as communication holes such as round holes or rectangular holes. Furthermore, the position of the communication portions is not limited to the structure of this example. The wiring 42 that constitutes the lighting fixture 17 is drawn from the storage space 40 to the wiring space 43 through the insertion portion 49.

[0089] The bottom plate portion 47 has a thin plate portion 50 in which a communicating portion 49 is formed, and a thick plate portion 51 that is thicker than the thin plate portion 50. In this example, the thin plate portion 50 is provided in the outdoor half of the bottom plate portion 47, and the thick plate portion 51 is provided in the indoor half of the bottom plate portion 47. Therefore, the communicating portion 49 is formed at both left and right end portions of the indoor side portion of the bottom plate portion 47.

[0090] The thick plate portion 51 has a plurality of mounting holes 52 that penetrate in the up-down direction. The mounting holes 52 are spaced apart in the left-right direction. In this example, each of the mounting holes 52 is configured as a screw hole.

[0091] The pair of side plate portions 48a, 48b are disposed approximately parallel to each other and spaced apart in the out-of-plane direction, and the lower end portions of each are connected to the out-of-plane end portion of the bottom plate portion 47. Therefore, the accommodation frame 35 has an opening 41 between the upper ends of the pair of side plate portions 48a, 48b. The plate thickness of the side plate portions 48a, 48b is approximately the same as the plate thickness of the thin plate portion 50 that constitutes the bottom plate portion 47.

[0092] In this example, the housing frame 35 has a pair of locking grooves 53a, 53b that open to face each other in the opening 41. The pair of locking grooves 53a, 53b are provided on the inner surfaces of the upper ends of the pair of side plate portions 48a, 48b that face each other. The locking grooves 53a, 53b are provided over the entire length of the side plate portions 48a, 48b in the left-right direction. The locking grooves 53a, 53b are formed between a pair of protrusions 66a, 66b (see FIGS. 13 and 14) that are spaced apart in the vertical direction and arranged parallel to each other. The protrusion 66b arranged on the lower side engages with the upper ends of the pair of side plates 45a, 45b that constitute the holding bracket 44, preventing the holding bracket 44 from slipping out of the housing space 40.

[0093] A transmission plate 54 that transmits light from an LED module serving as the light source 39 is engaged in the pair of engagement grooves 53a, 53b. In this way, the transmission plate 54 closes the opening 41 in the housing frame 35. As the transmission plate 54, for example, a polycarbonate plate that can diffuse the light from the light source 39 can be used.

[0094] In this example, the pair of side plate portions 48a, 48b have ridges 55a, 55b at the vertically middle portion of the inner surfaces facing each other. The ridges 55a, 55b closely face or abut against the pair of side plates 45a, 45b that make up the retaining bracket 44, preventing the retaining bracket 44 from rattling out of the plane inside the accommodation space 40.

[0095] In this example, the cover plate 36 has a generally flat plate shape and extends downward from the indoor-side end of the lower surface of the storage frame 35. The upper end of the cover plate 36 is connected to the lower end of the side plate portion 48b that constitutes the storage frame 35. The cover plate 36 and the side plate portion 48b constitute a single flat plate.

[0096] The left-right dimension of the cover plate 36 is the same as the left-right dimension of the storage frame 35. In other words, the cover plate 36 is provided over the entire left-right length of the storage frame 35. The plate thickness of the cover plate 36 is the same as the plate thickness of the side plate portion 48b.

[0097] In this example, the vertical dimension of the cover plate 36 is larger than the vertical dimension of the storage frame 35. However, when implementing a lighting fixture fixture according to one aspect of the present disclosure, the vertical dimension of the cover plate can be smaller than the vertical dimension of the storage frame, or the vertical dimension of the cover plate can be the same as the vertical dimension of the storage frame.

[0098] The lower end surface of the cover plate 36 is formed flat so as to be in surface contact with the upper surface of the horizontal plate portion 27 that constitutes the stringer 11a. The lower end of the cover plate 36 is made thicker than the rest of the cover plate 36 to prevent damage when the lighting fixture fixture 16 is extruded.

[0099] In this example, the left and right end openings of the housing frame 35 constituting the lighting fixture mount 16 are closed by covers 65 having a substantially L-shaped end face shape when viewed from the out-of-plane direction. The covers 65 are fixed to the bottom plate portion 47 constituting the housing frame 35 with bolts 66.

[0100] The lighting fixture fixture 16 is fixed to the stringer 11a constituting the louver unit 2 using a plurality of fixing brackets 34. However, when implementing a lighting fixture fixture according to one aspect of the present disclosure, the lighting fixture fixture can also be fixed directly to the decorative material unit.

[0101] The fixing bracket 34 is fixed to the lighting fixture mounting device 16 by a first fastening member 56, and is fixed to the louver unit 2 by a second fastening member 57. Specifically, the fixing bracket 34 is fixed to the bottom plate portion 47 of the storage frame 35 that constitutes the lighting fixture mounting device 16 by the first fastening member 56, and is fixed to the vertical plate portion 26 of the stringer 11a that constitutes the louver unit 2 by the second fastening member 57.

[0102] The fixed bracket 34 has a first fixed portion 58 and a second fixed portion 59 .

[0103] The first fixing portion 58 is configured in a flat plate shape and is fixed to the bottom plate portion 47 by a first fastening member 56 with its upper surface abutting against the lower surface of the bottom plate portion 47. In this example, the first fastening member 56 is configured as a bolt. Therefore, the first fixing portion 58 has a first through-hole 60 through which the first fastening member 56 can be inserted. In this example, the first fixing portion 58 is fixed to the bottom plate portion 47 by two first fastening members 56, and therefore the first fixing portion 58 has two first through-holes 60. With its upper surface abutting against the lower surface of the bottom plate portion 47, the first fixing portion 58 is fixed to the bottom plate portion 47 by inserting the first fastening member 56 through the first through-hole 60 from bottom to top and screwing it into the mounting hole 52 provided in the bottom plate portion 47. The tip (upper end) of the first fastening member 56 is disposed in the space between the bottom plate portion 47 and the connecting plate 46 that constitutes the holding bracket 44.

[0104] The second fixing portion 59 is fixed to the vertical plate portion 26 constituting the stringer 11a by a second fastening member 57. In this example, the second fastening member 57 is formed by a bolt. Therefore, the second fixing portion 59 has a second through-hole 61 through which the second fastening member 57 can be inserted. In this example, the second fixing portion 59 is fixed to the vertical plate portion 26 by two second fastening members 57, so the second fixing portion 59 has two second through-holes 61.

[0105] The second fixing portion 59 is not only fixed to the vertical plate portion 26 by the second fastening member 57, but is also hooked from above onto the upper end portion of the vertical plate portion 26. For this reason, the second fixing portion 59 has a hook-shaped (approximately U-shaped) cross section. The second fixing portion 59 has an outdoor-side plate portion 62 arranged on the outdoor side of the upper end portion of the vertical plate portion 26, an indoor-side plate portion 63 arranged on the indoor side of the upper end portion of the vertical plate portion 26, and a top plate portion 64 arranged above the upper end portion of the vertical plate portion 26.

[0106] The outdoor side plate portion 62 has a flat plate shape, and is fixed to the vertical plate portion 26 by abutting its indoor side against the outdoor side of the vertical plate portion 26 and screwing a second fastening member 57, which has been inserted through the second through hole 61 from the outdoor side to the indoor side, into the second through hole 28b provided in the vertical plate portion 26.

[0107] The indoor side plate portion 63 has a flat plate shape and is disposed approximately parallel to the outdoor side plate portion 62. The lower end portion of the indoor side plate portion 63 is connected to the outdoor side end portion of the first fixing portion 58. With the first fixing portion 58 fixed to the bottom plate portion 47 of the housing frame 35, the indoor side plate portion 63 is overlapped without any gaps with the side plate portion 48a, which is disposed on the outdoor side of the pair of side plate portions 48a, 48b that constitute the housing frame 35.

[0108] The top plate portion 64 has a flat plate shape, and when the second fixing portion 59 is hooked from above onto the upper end portion of the vertical plate portion 26, its lower surface comes into surface contact with the upper end surface of the vertical plate portion 26. The top plate portion 64 is disposed adjacent to the outdoor side of the transmission plate 54 that closes the opening 41 of the housing frame 35.

[0109] According to this example, the lighting fixture 17 can be placed in the limited space between the louver 10 and the curtain wall 1, and the wiring 42 of the lighting fixture 17 can be hidden.

[0110] That is, the lighting fixture mounting fixture 16 comprises a storage frame 35 having an interior storage space 40 capable of storing a light source 39 of the lighting fixture 17 and an opening 41 through which light from the light source 39 passes, and a cover plate 36 extending downward from the storage frame 35 and with its lower end abutting or closely facing the stringer 11a, and a wiring space 43 for storing wiring 42 of the lighting fixture 17 is formed in the area surrounded by the underside of the storage frame 35, the side surface of the cover plate 36, and the stringer 11a.

[0111] Therefore, the lighting fixture mounting fixture 16 allows the light source 39 and wiring 42 that make up the lighting fixture 17 to be arranged in a vertically stacked manner, so that the lighting fixture 17 can be placed in the limited space between the louver 10 and the curtain wall 1.

[0112] Furthermore, the lighting fixture mount 16 can accommodate the wiring 42 of the lighting fixture 17 in the wiring space 43 formed in the area surrounded by the underside of the housing frame 35, the side surface of the cover plate 36, and the stringer 11a, so that the wiring 42 can be hidden. Specifically, the wiring 42 can be hidden from both the indoor and outdoor sides.

[0113] In this example, the bottom plate portion 47 that constitutes the storage frame 35 is provided with a communication portion 49 that connects the storage space 40 and the wiring space 43, so that the wiring 42 can be pulled out from the storage space 40 to the wiring space 43 through the communication portion 49, and moisture such as rainwater that has entered the storage space 40 can be discharged to the outside through the wiring space 43.

[0114] In this example, the bottom plate portion 47 that constitutes the housing frame 35 is made up of a thin plate portion 50 and a thick plate portion 51, and the communication portion 49 is formed in the thin plate portion 50, which improves the workability of forming the communication portion 49. Furthermore, in this example, the thick plate portion 51 has mounting holes 52 for screwing in the first fastening members 56 that secure the lighting fixture fixture 16 and the fixing bracket 34, so that the screwing length of the first fastening members 56 can be sufficiently ensured.

[0115] In this example, the opening 41 of the storage frame 35 has a pair of locking grooves 53a, 53b that open facing each other, so that the transparent plate 54 for closing the opening 41 can be easily attached to the storage frame 35 using the pair of locking grooves 53a, 53b.

[0116] In this example, the lighting fixture mounting fixture 16 is fixed to the stringer 11a that constitutes the louver unit 2 using a fixing bracket 34 that is configured separately from the lighting fixture mounting fixture 16, which simplifies the structure of the lighting fixture mounting fixture 16 and increases the versatility of the lighting fixture mounting fixture 16.

[0117] The second fixing portion 59 constituting the fixing bracket 34 is not only fixed to the vertical plate portion 26 constituting the stringer 11a by the second fastening member 57, but also has a configuration in which it is hooked from above, which improves the workability of fixing the fixing bracket 34 to the stringer 11a and effectively prevents the fixing bracket 34 and the lighting fixture mounting fixture 16 from falling off.
