Description

Door and window equipment

[0001] The present disclosure relates to a joinery device.

[0002] Devices incorporating solar cells into fixtures such as doors have been known for some time. For example, Patent Document 1 below discloses a door structure in which a door configured as a double sliding door is provided with a door frame into which a solar panel is embedded. In this door structure, the output wiring of the solar cells of the solar panel provided on the door is connected to a battery provided within a transom located above the door.

[0003] Japanese Patent Application Laid-Open No. 2003-293664

[0004] However, in the door structure described in Patent Document 1, it is necessary to connect the solar cell on the door to the battery inside the door frame by output wiring, and further improvement is desired.

[0005] The present disclosure has been made in consideration of the above-mentioned circumstances, and aims to provide a fitting device that can easily establish an electrical connection between a fitting having a solar cell module and a fitting frame.

[0006] In order to achieve the above-mentioned objectives, the building fixture device of the present disclosure comprises a building fixture having a sash portion that surrounds the four peripheral edges of a panel portion that includes a solar cell module, and a building fixture frame to which the building fixture is attached, and the upper and lower sash portions of the sash portion are provided with receiving grooves that receive rail portions provided on the upper and lower frames of the building fixture frame, and the inner surface of one of the upper and lower receiving grooves is provided with a power transmission unit that transmits power generated by the solar cell module, and the outer surface of the rail portion that is inserted into one of the receiving grooves is provided with a power receiving unit that receives power by contacting the power transmission unit.

[0007] The fitting device according to the present disclosure has the above-described configuration, and thus can easily establish an electrical connection between the fitting having the solar cell module and the fitting frame.

[0008] 1 is a schematic front view showing an example of a fitting device according to an embodiment of the present disclosure; FIG. 2 is a partially cutaway schematic cross-sectional view corresponding to the X-X arrow view in FIG. 1; and FIG. 3 is a partially cutaway schematic vertical cross-sectional view corresponding to the Y-Y arrow view in FIG. 1. (a) is a partially cutaway schematic perspective view of the fitting device, (b) and (c) are schematic views showing a modified example of the fitting device, (b) is a partially cutaway schematic perspective view corresponding to (a), and (c) is a partially cutaway schematic horizontal cross-sectional view. (a) to (c) are partially cutaway schematic vertical cross-sectional views each showing a modified example of the fitting device.

[0009] Hereinafter, embodiments of the present disclosure will be described with reference to the drawings. In some drawings, some of the detailed reference numerals used in other drawings are omitted. In the following embodiments, directions such as the up and down directions will be described based on the state in which an example of a fitting device according to this embodiment is installed.

[0010] 1 to 5 are schematic diagrams showing an example of a fitting device according to the present embodiment and one modified example thereof. As shown in FIGS. 1 to 3, the fitting device 1 according to the present embodiment comprises a fitting 20 having a stile 30 surrounding the four periphery edges of a panel 21 including a solar cell module 24, and a fitting frame 10 to which the fitting 20 is attached. With this configuration, electricity can be generated in the solar cell module 24 of the fitting 20. As shown in FIG. 3, the upper and lower stiles 36 and 33 of the stile 30 are provided with receiving grooves 37 and 34 that receive rails 15 and 13 provided on the upper and lower frames 14 and 12 of the fitting frame 10. A power transmission unit 38 that transmits the electricity generated by the solar cell module 24 is provided on the inner surface (37a) of one of these upper and lower receiving grooves 37, 34, and a power receiving unit 16 that receives electricity by contacting the power transmission unit 38 is provided on the outer surface (15a) of the rail portion 15 that is inserted into this one receiving groove 37.

[0011] With the above-described configuration, when the fitting 20 is installed so that the rails 15, 13 of the upper and lower frames 14, 12 of the fitting frame 10 are received in the upper and lower receiving grooves 37, 34, the power transmission portion 38 of the receiving groove 37 of the fitting 20 contacts the power receiving portion 16 of the rail portion 15, enabling electrical connection. This facilitates electrical connection between the fitting 20 and the fitting frame 10 compared to a configuration requiring connection of output wiring, etc. Furthermore, because the power transmission portion 38 is provided on the inner surface (37a) of the receiving groove 37, it is less likely to be exposed to the outside, thereby reducing contact with the power transmission portion 38. In this embodiment, the power transmission portion 38 is provided on the upper frame portion 36, and the power receiving portion 16 is provided on the upper frame 14. This configuration is less susceptible to the effects of rainwater, etc., compared to a configuration in which the power transmission portion is provided on the lower frame portion 33 and the power receiving portion is provided on the lower frame 12.

[0012] Specifically, this fitting device 1 may be installed in an opening that penetrates a wall that separates the interior and exterior of a building. This fitting device 1 may be installed by fixing the fitting frame 10 to an appropriate frame substrate such as a lintel, window sill, or pillar that separates the four perimeters of the opening. This fitting device 1 may constitute a window device such as a waist-high window that has a vertical dimension ranging from about waist height of an adult to a suitable height on the ceiling side, or a bay window that has a vertical dimension ranging from floor to a suitable height on the ceiling side, or may even constitute a door device.

[0013] In this embodiment, as shown in Figure 2, the fitting device 1 is configured with multiple fittings 20, 20 (two in the illustrated example) attached to the fitting frame 10 in a sliding manner. The fittings 20, 20 are slidable along the longitudinal direction of the rails 15, 13 and include an exterior fitting 20A arranged on the exterior (outdoor) side within the fitting frame 10 and an interior fitting 20B arranged on the interior (indoor) side. These exterior fittings 20A and interior fittings 20B have substantially the same configuration, and in the following, when there is no need to distinguish between the exterior fittings 20A and the interior fittings 20B, one of them will be described as the fitting 20. Furthermore, when there is no need to distinguish between the parts, etc., provided on the exterior and interior sides of the fitting frame 10 corresponding to the exterior fittings 20A and the interior fittings 20B, the terms "outdoor" and "indoor" will be omitted and the parts will be referred to collectively.

[0014] As shown in FIG. 1 , the door frame 10 is formed into a rectangular frame shape by left and right vertical frames 11, 11 that are elongated in the vertical direction, and an upper frame 14 and a lower frame 12 that are elongated in the horizontal direction. These left and right vertical frames 11, 11, upper frame 14, and lower frame 12 may be made of metal, or may be made of resin from the viewpoint of thermal insulation, or may be made of so-called fiber-reinforced resin containing reinforcing fibers such as glass fiber or carbon fiber. Furthermore, these left and right vertical frames 11, 11, upper frame 14, and lower frame 12 may each be an extrusion molded product having a substantially uniform cross-sectional shape along their entire length. Furthermore, these left and right vertical frames 11, 11, upper frame 14, and lower frame 12 may be joined to each other by suitable fasteners such as screws, welding, or the like. In the illustrated example, the longitudinal ends of the left and right vertical frames 11, 11 are joined to the longitudinal ends of the upper frame 14 and lower frame 12 in a so-called jointed manner, but they may also be joined in a vertical or horizontal manner. The interior ends of the inner periphery of the left and right vertical frames 11, 11, upper frame 14, and lower frame 12 are provided with cover pieces that extend to cover the door-end, upper end, and lower end of the fixture 20. The outer periphery of the left and right vertical frames 11, 11, upper frame 14, and lower frame 12 may be provided with appropriate gaskets that elastically deform and fit tightly to the frame base.

[0015] The rail portion 13 of the lower frame 12 protrudes from the projected surface (the surface facing upward) of the lower frame 12 toward the upper frame 14 and extends substantially the entire length of the lower frame 12. As shown in FIG. 3 , the lower frame 12 is provided with the rail portion 13, which includes an exterior rail portion 13A that guides the lower end of the exterior fitting 20A and an interior rail portion 13B that guides the lower end of the interior fitting 20B. The exterior rail portion 13A and the interior rail portion 13B are arranged parallel to each other with a gap in the projected direction (the direction along the thickness of the fitting) of the lower frame 12. The projected dimension between the exterior rail portion 13A and the interior rail portion 13B may be appropriately determined depending on the thickness of the exterior fitting 20A and the interior fitting 20B so that they are arranged close to each other. These outdoor rail portion 13A and indoor rail portion 13B are approximately plate-shaped and arranged so that the thickness direction is the prospective direction, and on each upper end surface, an engaging protrusion that protrudes upward and extends over approximately the entire length to engage with the door roller 35 of the building fixture 20 described below.

[0016] The rail portion 15 of the upper frame 14 is provided so as to protrude from the projected surface (the surface facing downward) of the upper frame 14 toward the lower frame 12 and extend over substantially the entire length of the upper frame 14. The upper frame 14 is provided with the rail portion 15, which includes an exterior rail portion 15A that guides the upper end of the exterior fitting 20A and an interior rail portion 15B that guides the upper end of the interior fitting 20B. The exterior rail portion 15A and the interior rail portion 15B are provided parallel to each other and spaced apart in the projected direction of the upper frame 14. The exterior rail portion 15A of the upper frame 14 is provided directly above the exterior rail portion 13A of the lower frame 12, and the interior rail portion 15B of the upper frame 14 is provided directly above the interior rail portion 13B of the lower frame 12. The exterior rail portion 15A and the interior rail portion 15B are generally plate-shaped and arranged with their thickness direction aligned with the projection direction. An example of the specific configuration of the power receiving unit 16 provided on the rail portion 15 of the upper frame 14 will be described later. The left and right vertical frames 11, 11 may also be provided with protruding pieces extending along substantially their entire length, protruding in directions facing each other so as to be aligned with the rail portions 15, 13 of the upper frame 14 and the lower frame 12 in the projection direction. Note that the door frame 10 is not limited to the configuration shown in the illustration, and various other configurations may be used.

[0017] As shown in FIGS. 1 to 3 , the fitting 20 comprises a rectangular panel portion 21 and a frame portion 30 surrounding the four periphery of the panel portion 21. As shown in FIG. 3 , the panel portion 21 has a multi-layered structure with multiple (two in the illustrated example) light-transmitting plates 22, 22 extending along the thickness of the fitting. These light-transmitting plates 22, 22 may be glass plates or may be made of a synthetic resin material such as acrylic or polycarbonate. The light-transmitting plates 22, 22 are spaced apart in the thickness direction by appropriate spacers 23 formed in a roughly frame shape along the four periphery. Additionally, an appropriate sealant may be provided around the outer periphery of the spacer 23 to seal the vacuum layer or hollow space filled with various gases between the light-transmitting plates 22, 22.

[0018] The solar cell module 24 is disposed along one thickness-wise surface of one of the light-transmitting plates 22, 22 of the panel unit 21. In the illustrated example, the solar cell module 24 is disposed along the exterior-facing surface of the exterior-side light-transmitting plate 22, but this is not limiting. The solar cell module 24 may include a single or multiple thin-film solar cells including a photoelectric conversion layer formed by coating or the like on the light-transmitting plate 22 or an appropriate substrate. Examples of such thin-film solar cells include perovskite-type solar cells that use a perovskite compound as a light-absorbing material, as well as silicon-type solar cells. The solar cell module 24 is translucent and may be disposed over substantially the entire thickness-wise surface of the light-transmitting plate 22 of the panel unit 21. The solar cell module 24 is provided with positive and negative electrodes, which are electrically connected to appropriate electric wires 25, 25.

[0019] As shown in Figure 1, the stile 30 is a rectangular frame made up of a leading stile 31 and a joining stile 32, which constitute left and right vertical stiles elongated in the vertical direction, and an upper stile 36 and a lower stile 33, which are elongated in the horizontal direction. The leading stile 31, joining stile 32, upper stile 36, and lower stile 33 may be made of metal, but as mentioned above, they may also be made of resin from the perspective of thermal insulation, or may be made of fiber-reinforced resin. The leading stile 31, joining stile 32, upper stile 36, and lower stile 33 may also be extrusion molded products with a substantially uniform cross-sectional shape along their entire length. The door end frame 31, the joint frame 32, the upper frame 36, and the lower frame 33 may be joined to each other by suitable fasteners such as screws, welding, etc. In the illustrated example, the longitudinal ends of the left and right door end frames 31 and the joint frame 32 are joined to the longitudinal ends of the upper frame 36 and the lower frame 33 in a so-called jointed manner, but they may also be joined in a vertical or horizontal manner.

[0020] As shown in Figure 3, panel receiving grooves 30a that receive the four peripheral edges of the panel section 21 are provided on the inner periphery of each of these end stile sections 31, joint stile section 32, upper stile section 36, and lower stile section 33. The indoor side, which is on one side of the groove width direction of the panel receiving groove 30a, is defined by extension pieces that extend from the indoor side edges of the inner periphery of each of the end stile section 31, joint stile section 32, upper stile section 36, and lower stile section 33 so as to cover the edge of the panel section 21. The outdoor side, which is on the other side of the groove width direction of the panel receiving groove 30a, is defined by ridge members 30b attached to the outdoor side edges of each of the end stile section 31, joint stile section 32, upper stile section 36, and lower stile section 33. In the illustrated example, a receiving base 26 is interposed between the bottom of the panel receiving groove 30a and the outer peripheral end face of the panel portion 21, but this is not a limitation. Also, an appropriate gasket that fits tightly against the panel portion 21 may be provided inside the panel receiving groove 30a so as to extend around substantially the entire circumference. The panel receiving groove 30a that receives the four peripheral ends of the panel portion 21 is not limited to a configuration in which the other side in the groove width direction is defined by a pressing edge member 30b as in the illustrated example, and various other configurations may be used.

[0021] The receiving groove 34 of the lower frame portion 33 is provided so as to open downward and extend over substantially the entire length of the lower frame portion 33. A door roller 35 is provided in the lower frame portion 33 so as to be exposed at the bottom of the receiving groove 34. The door roller 35 is held by an appropriate bearing portion so as to be rotatable around an axis along the thickness direction of the fitting. The door roller 35 rolls along the rail portion 13 of the lower frame 12, guiding the lower end side of the fitting 20 in the left-right direction. The outer peripheral surface of the door roller 35 is provided with an engagement groove that opens radially outward, extends around the entire circumference, and engages with an engagement protrusion of the rail portion 13 of the lower frame 12. The door rollers 35 may be provided at multiple locations (e.g., two locations) along the length of the lower frame portion 33. Seal portions 33a, 33a are provided on both edges of the receiving groove 34 in the opening width direction, extending in directions facing each other and with their leading ends in the extending direction approaching or abutting the rail portion 13. These seal portions 33a, 33a are provided so as to extend over substantially the entire length of the receiving groove 34. These seal portions 33a, 33a may be formed from, for example, a soft resin such as soft PVC (polyvinyl chloride), a thermoplastic elastomer (TPE), rubber, or the like.

[0022] The door end stile 31 and the door joint stile 32 may also be provided with receiving grooves that receive the protruding pieces provided on the left and right vertical frames 11, 11. Similar seals may also be provided on both edges of the receiving grooves in the opening width direction of the door end stile 31 and the door joint stile 32. An appropriate handle may also be provided in an appropriate location on the door end stile 31. The door joint stile 32 of the exterior fitting 20A and the door joint stile 32 of the interior fitting 20B, which are arranged so as to overlap in the fitting thickness direction in the closed position, may be provided with appropriate seals that abut or are close to each other, or with appropriate locking devices such as crescent locks.

[0023] The receiving groove 37 of the upper frame portion 36 is formed to open upward and extend substantially the entire length of the upper frame portion 36. The receiving groove 37 is defined by inner surfaces 37a, 37a on both sides in the groove width direction and an inner bottom surface 37b at the groove bottom, forming an approximately rectangular groove shape. The groove depth of the receiving groove 37 may be any appropriate dimension so that, when installing the fitting 20 in a so-called "kendon" shape, the rail portion 13 of the lower frame 12 can be received in the receiving groove 34 of the lower frame portion 33 while the rail portion 15 of the upper frame 14 is received therein. Similar to the receiving groove 34 of the lower frame portion 33, seal portions 36a, 36a are provided on both edges of the opening width direction of the receiving groove 37, extending in directions facing each other and with their extending ends approaching or abutting the rail portion 15.

[0024] A power transmitting unit 38 is provided on at least one of the inner surfaces 37a, 37a on both sides in the groove width direction of the receiving groove 37, and a power receiving unit 16 is provided on at least one of the outer surfaces 15a, 15a in the projection direction of the rail portion 15 of the upper frame 14 that faces the inner surfaces 37a, 37a. This configuration can reduce poor contact due to the accumulation of dust, etc., compared to a configuration in which the power transmitting unit is provided on the inner bottom surface 37b on the groove bottom side of the receiving groove 37 and the power receiving unit is provided on the underside 15b of the rail portion 15 that faces it. One of the power transmitting unit 38 and the power receiving unit 16 is an elongated current-carrying portion 39 that is elongated in the longitudinal direction of the rail portion 15, and the other is a terminal portion 17 that contacts the elongated current-carrying portion 39. With this configuration, electricity can be supplied to the door frame 10 when the door frame 20 is slid along the rail portion 15 or when it is in the open position, and compared to a configuration in which electricity can be supplied only in a specified position such as the closed position, the electricity generated by the solar cell module 24 can be received efficiently on the door frame 10 side.

[0025] The terminal portion 17 is biased toward the elongated current-carrying portion 39. With this configuration, as described above, electricity can be stably passed when the fitting 20 is slid along the rail portion 15 or even if there is a fitting error. One of the width dimension of the elongated current-carrying portion 39 and the dimension of the corresponding terminal portion 17 is larger than the other. With this configuration, as described above, electricity can be stably passed when the fitting 20 is slid along the rail portion 15 or even if there is a fitting error.

[0026] Specifically, elongated conductive portions 39, 39 constituting a pair of power transmission portions 38, 38 are provided on each of the inner surfaces 37a, 37a on both sides of the receiving groove 37 in the groove width direction. One of these elongated conductive portions 39, 39 may be electrically connected to the positive electrode of the solar cell module 24 via an appropriate electric wire 25 or the like, and the other may be electrically connected to the negative electrode of the solar cell module 24 via an appropriate electric wire 25 or the like. These elongated conductive portions 39, 39 are provided on the inner surfaces 37a, 37a on the groove opening side, which are formed in a stepped shape from the groove bottom side so that the groove width dimension is smaller than that of the groove bottom side of the receiving groove 37 (see also FIG. 4(a)). These elongated conductive portions 39, 39 are provided at the same height and have the same width dimension. These elongated conductive portions 39, 39 may be provided to extend substantially the entire length of the groove in the groove longitudinal direction (see also FIG. 2). These long conductive portions 39, 39 may be made of an appropriate metal or the like having good conductivity.

[0027] The power receiving unit 16 (terminal unit 17) is positioned so that it always overlaps the fitting 20, which slides between the closed position and the fully open position, in a plan view. With this configuration, the power receiving unit 16 (terminal unit 17) on the fitting frame 10 is always positioned where the fitting 20, which slides in the opening / closing direction, is present, thereby preventing unintended contact with the power receiving unit 16 (terminal unit 17). As shown in FIG. 2 , the power receiving unit 16 (terminal unit 17) is positioned so that it always overlaps the joint frame portion 32 of the fitting 20 in the closed position. With this configuration, it is possible to effectively increase the effective opening width in the fully open position, while, as described above, the power receiving unit 16 (terminal unit 17) on the fitting frame 10 is always positioned where the fitting 20, which slides in the opening / closing direction, is present, thereby preventing unintended contact with the power receiving unit 16 (terminal unit 17).

[0028] Specifically, terminal portions 17, 17 constituting a pair of power receiving portions 16, 16 are provided on each of the outer surfaces 15 a, 15 a on both sides of the rail portion 15 of the upper frame 14 in the prospective direction. One of these terminal portions 17, 17 may be conducted to the positive electrode of the solar cell module 24 via a long current-carrying portion 39 and an appropriate electric wire 25, etc., and the other may be conducted to the negative electrode of the solar cell module 24 via a long current-carrying portion 39 and an appropriate electric wire 25, etc. In addition, the door frame 10 may be provided with a power storage unit or the like that stores the power received at these terminal portions 17, 17, and may further be provided with a drive unit that uses that power to open and close the door 20. Instead of or in addition to providing such a power storage unit or drive unit on the door frame 10 side, a configuration may be adopted in which they are provided on the door 20 side. Furthermore, the fitting device 1 may be configured as a solar power generation system by electrically connecting these terminal portions 17, 17 to an appropriate power storage device or the like provided outside the fitting device 1 by appropriate electric wires or the like.

[0029] These terminals 17, 17 are positioned so that they are aligned with each other in the longitudinal direction of the rail portion 15. The dimension of these terminals 17, 17 along the rail longitudinal direction may be smaller than the dimension along the front (left-right) direction of the joint stile portion 32. As shown in FIG. 3, these terminals 17, 17 are positioned at the same height and have the same width along the vertical direction. In the illustrated example, the width of these terminals 17, 17 is smaller than the width of the elongated conductive portions 39, 39, but they may be larger. The width of these terminals 17, 17 and the elongated conductive portions 39, 39 may be approximately 1.1 to 2 times, or 1.2 to 1.6 times, that of the other. Alternatively, the width of these terminals 17, 17 and the elongated conductive portions 39, 39 may be approximately the same. These terminal portions 17, 17 have the same configuration, so one of them will be described below as an example.

[0030] 2 and 4(a), the terminal portion 17 includes a fixed piece 17a fixed along the outer surface 15a of the rail portion 15, and a spring-like piece 17b connected to the fixed piece 17a and protruding outward from the outer surface 15a in the projection direction. The terminal portion 17 is configured such that the fixed piece 17a is provided on both sides of the spring-like piece 17b in the longitudinal direction of the rail. This configuration allows for more stable contact of the elongated conductive portion 39 when it rubs against the rail as the fitting 20 is opened or closed, and also prevents peeling, etc., compared to a configuration in which the spring-like piece 17b is cantilevered from the fixed piece 17a. The spring-like pieces 17b are formed in a pantograph (diamond) shape, and include pieces that are inclined so as to move apart from the opposing end portions of the fixed pieces 17a on both sides in the outward direction, and inclined pieces that are inclined so as to move closer to each other in the outward direction from the ends of the inclined pieces that move apart, with their tips connected to each other. The tips of the spring-like pieces 17b come into contact with the elongated current-carrying parts 39 as the spring-like pieces 17b elastically deform.

[0031] The terminal 17 described above may be formed from an appropriate metal or the like having good conductivity. The spring-like piece 17b of the terminal 17 is not limited to the above configuration and may be configured to be elastically deformable generally in the projection direction and to contact the elongated current-carrying portion 39 with elastic deformation, or may have various other configurations. Furthermore, the terminal 17 biased toward the elongated current-carrying portion 39 is not limited to a configuration in which the contact portion with the elongated current-carrying portion 39 itself is the spring-like piece 17b. It may also be configured such that the contact portion with the elongated current-carrying portion 39 is biased by an appropriate spring or the like separate from the contact portion and is capable of expanding and contracting generally in the projection direction. For example, the terminal 17 may include a pin-shaped electrode or an umbrella-shaped electrode biased in the projection direction by a spring or the like.

[0032] 2, the above-described seal portions 36a are cut away to show the terminal portions 17 on both sides of the rail portion 15. When the rail portion 15 is inserted into the receiving groove 37, the terminal portions 17 and the seal portions 36a may be elastically deformed. The seal portions 36a may have appropriate notches or the like to facilitate the reception of the terminal portions 17, or portions of the seal portions 36a may be removed to allow the reception of the terminal portions 17. In the above example, the terminal portions 17 are positioned so as to overlap the joint frame portion 32 of the door frame 20 in the closed position in a plan view. However, the present invention is not limited to this example, and the terminal portions may be positioned in other locations.

[0033] Next, modified examples of the fitting device will be described with reference to Figures 4(b), (c) and 5(a) to (c). In each of the following modified examples, differences from the previously described example will be mainly described, and explanations of similar configurations will be omitted or briefly explained. In addition, in each of the following modified examples, explanations of the effects achieved similarly to the previously described example will be omitted or briefly explained.

[0034] 4(b) and (c) schematically illustrate a fitting device 1A according to a first modification. In this modification, the power receiving portion 16A provided on the upper frame 14A is a long conductive portion 17A extending in the longitudinal direction of the rail portion 15, and the power transmitting portion 38A provided on the upper frame portion 36A is a terminal portion 39A that contacts the long conductive portion 17A. Long conductive portions 17A, 17A similar to the long conductive portion 39 described above are provided extending from the outer surfaces 15a, 15a on both sides of the rail portion 15 of the upper frame 14A. These long conductive portions 17A, 17A are positioned at the same height and have the same width. These long conductive portions 17A, 17A may be provided along substantially the entire length of the rail portion 15.

[0035] Terminal portions 39A, 39A similar to the terminal portion 17 described above are provided on the inner surfaces 37a, 37a on both sides of the receiving groove 37 of the upper frame portion 36A. These terminal portions 39A, 39A, like the above, include a fixed piece 39a fixed to the inner surface 37a and a spring-like piece 39b. These terminal portions 39A, 39A are provided at the same height and have the same width dimension along the vertical direction. These terminal portions 39A, 39A may be provided so that they are aligned with each other in the left-right direction of the fixture (the longitudinal direction of the rail portion 15). These terminal portions 39A, 39A may be provided so that they are located in the center of the fixture in the left-right direction, or at one end of the left-right direction, etc.

[0036] FIG. 5( a) schematically illustrates a second modified example of a fitting device 1B.
