[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 embodiment, directions such as the up and down directions will be described based on the state in which an example of the fitting device according to this embodiment is installed.

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

[0011] With the above configuration, when the fitting 20 is installed so that the rail portions 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 comes into contact with the power receiving portion 16 of the rail portion 15, allowing electricity to flow. This makes it easier to electrically connect the fitting 20 and the fitting frame 10 compared to a configuration that requires connecting output wiring, etc. Also, 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, and contact with the power transmission portion 38 can be suppressed. In this embodiment, the power transmitting unit 38 is provided in the upper frame 36, and the power receiving unit 16 is provided in the upper frame 14. This configuration is less susceptible to the effects of rainwater, etc., compared to a configuration in which the power transmitting unit is provided in the lower frame 33 and the power receiving unit is provided in 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 FIG. 2, the fitting device 1 is configured such that multiple fittings 20, 20 (two in the illustrated example) are attached to the fitting frame 10 in a sliding manner. The fittings 20, 20 are slidable along the longitudinal direction of the rail portions 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 used as an example and 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, they will be referred to collectively, omitting the terms exterior and interior.

[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 fitting 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 is provided so as to protrude from the visible surface (surface facing upward) of the lower frame 12 toward the upper frame 14 and extend over substantially the entire length of the lower frame 12. As shown in Figure 3, the lower frame 12 is provided with, as rail portion 13, an outdoor rail portion 13A that guides the lower end side of the outdoor fitting 20A and an indoor rail portion 13B that guides the lower end side of the indoor fitting 20B. The outdoor rail portion 13A and the indoor rail portion 13B are arranged parallel to each other with a gap between them in the projection direction (direction along the thickness direction of the fittings) of the lower frame 12. The projection dimension between the outdoor rail portion 13A and the indoor rail portion 13B may be an appropriate dimension depending on the thickness of the outdoor fittings 20A and the indoor fittings 20B guided by them so that they are arranged close to each other. These exterior rail portion 13A and interior rail portion 13B are roughly plate-shaped and arranged so that the thickness direction is the prospective direction, and on each upper end surface, an engaging protrusion that engages with the door roller 35 of the door fixture 20 described below protrudes upward and extends over roughly the entire length.

[0016] The rail portion 15 of the upper frame 14 is provided so as to protrude from the visible 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, as the rail portion 15, an outdoor rail portion 15A that guides the upper end side of the outdoor fitting 20A and an indoor rail portion 15B that guides the upper end side of the indoor fitting 20B. The outdoor rail portion 15A and the indoor rail portion 15B are arranged parallel to each other with a gap between them in the projection direction of the upper frame 14. The outdoor rail portion 15A of the upper frame 14 is arranged so as to be located directly above the outdoor rail portion 13A of the lower frame 12, and the indoor rail portion 15B of the upper frame 14 is arranged so as to be located directly above the indoor 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 so that the thickness direction is the projection direction. An example of a 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 over approximately their entire length so that they protrude in directions facing each other and are positioned to coincide in the prospective direction with the rail portions 15, 13 of the upper frame 14 and the lower frame 12. Note that the door and window 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 plate-shaped panel portion 21 and a frame portion 30 surrounding the four peripheral edges of the panel portion 21. As shown in Fig. 3, the panel section 21 has a multi-layer structure having a plurality of light-transmitting plates 22, 22 (two in the illustrated example) in the thickness direction of the fixture. These light-transmitting plates 22, 22 may be glass plates or may be formed from a synthetic resin material such as acrylic or polycarbonate. These light-transmitting plates 22, 22 are spaced apart in the thickness direction via appropriate spacers 23 formed in a roughly frame shape along the four peripheral edges. In addition, an appropriate sealant may be provided around the outer periphery of the spacer 23 to seal the vacuum layer or hollow layer filled with various gases between the light-transmitting plates 22, 22.

[0018] The solar cell module 24 is provided along one surface in the thickness direction of one of the light-transmitting plates 22, 22 of the panel unit 21. In the illustrated example, the solar cell module 24 is provided along the surface of the light-transmitting plate 22 on the outdoor side that faces the outdoor side, but the present invention is not limited to this example. This solar cell module 24 may include a single or multiple thin-film solar cell cells including a photoelectric conversion layer formed by coating or the like on the light-transmitting plate 22 or an appropriate substrate. Such thin-film solar cells may be, for example, perovskite-type solar cells that use a perovskite-type compound as a light-absorbing material, or other solar cells such as silicon-type solar cells. This solar cell module 24 has light-transmitting properties and may be provided over substantially the entire surface of one 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, and appropriate electric wires 25, 25 are electrically connected to these electrodes.

[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 door joint frame 32, the upper frame 36, and the lower frame 33 may be joined together by suitable fasteners such as screws, or by welding, etc. In the example shown, the longitudinal ends of the left and right door end frames 31 and the door 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 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 the end stile section 31, joint stile section 32, upper stile section 36, and lower stile section 33. In the illustrated example, an example is shown in which 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 limited to this example. Also, an appropriate gasket that comes into close contact with 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 (for example, two locations) in the longitudinal direction 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 being close to or in contact with 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 provided so as to open upward and extend over 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 that constitute the inner surface of the receiving groove 37, and an inner bottom surface 37b on the groove bottom side, and is formed in a substantially rectangular groove shape. The groove depth dimension of this receiving groove 37 may be an appropriate dimension so that when the fitting 20 is installed 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. 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 of this receiving groove 37, which extend in directions facing each other and whose tip ends in the extending direction are close to or abut 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 face the inner surfaces 37a, 37a. With this configuration, poor contact due to the accumulation of dust and the like can be reduced compared to a configuration in which a power transmitting unit is provided on the inner bottom surface 37b on the groove bottom side of the receiving groove 37 and a 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 a long current-carrying unit 39 that is long in the longitudinal direction of the rail unit 15, and the other is a terminal unit 17 that contacts this long current-carrying unit 39. With this configuration, electricity can be passed when the fitting 20 is slid along the rail unit 15 or in the open position, and compared to a configuration in which electricity can be passed only in a predetermined position such as the closed position, the electricity generated in the solar cell module 24 can be received efficiently on the fitting frame 10 side.

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

[0026] Specifically, elongated conductive portions 39, 39 constituting a pair of power transmission portions 38, 38 are provided on 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 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 provided in a position that always overlaps in a plan view with the fitting 20 that slides between the closed position and the fully open position. With this configuration, the power receiving unit 16 (terminal unit 17) on the fitting frame 10 side is always in a position where the fitting 20 that slides in the opening and closing direction is always present, making it possible to prevent unintentional contact with the power receiving unit 16 (terminal unit 17). As shown in Figure 2, the power receiving unit 16 (terminal unit 17) is provided in a position that overlaps with the joint frame portion 32 of the fitting 20 in the closed position in a plan view. 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 side is in a position where the fitting 20 that slides in the opening and closing direction is always present, thereby preventing unintentional 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 projection 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. Furthermore, 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 have these terminal portions 17, 17 electrically connected to an appropriate power storage device or the like provided outside the fitting device 1 by appropriate electric wires or the like to form a solar power generation system.

[0029] These terminal portions 17, 17 are provided so as to be aligned with each other in the longitudinal direction of the rail portion 15. The dimension of these terminal portions 17, 17 along the longitudinal direction of the rail may be smaller than the dimension of the joining frame portion 32 along the facing direction (left-right direction). As shown in FIG. 3, these terminal portions 17, 17 are positioned at the same height and have the same width in the up-down direction. In the illustrated example, the width of these terminal portions 17, 17 is smaller than the width of the elongated conductive portions 39, 39, but they may be larger. The width of these terminal portions 17, 17 and the width of 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 terminal portions 17, 17 and the width of 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 rail longitudinal direction. Compared to a configuration in which the spring-like piece 17b is cantilevered from the fixed piece 17a, this configuration allows for more stable contact when the elongated conductive portion 39 rubs against the rail as the fitting 20 is opened or closed, and also prevents peeling and other problems. The spring-like pieces 17b are formed in a pantograph (diamond) shape and include pieces that incline so as to move apart from the opposing end portions of the fixed pieces 17a on both sides toward the outside in the projection direction, and inclined pieces that incline so as to move closer to each other from the ends of the separated inclined pieces toward the outside in the projection direction, 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 portion 17 may be made of an appropriate metal or the like having good electrical conductivity. The spring-like piece 17b of the terminal 17 is not limited to the above configuration, but 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, but may 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 shown 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 be provided with appropriate notches or the like to facilitate the reception of the terminal portions 17, and further, 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, 17 are provided at a position that overlaps with the joint frame portion 32 of the door fitting 20 in the closed position in a plan view, but this is not limited to this example and the terminal portions may be provided at other positions.

[0033] Next, a modified example of the fitting device will be described with reference to FIGS. 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 those of the previously described example will be omitted or briefly explained.

[0034] 4(b) and (c) schematically show a fitting device 1A according to a first modified example. In this modified example, the power receiving portion 16A provided on the upper frame 14A is a long-shaped current-carrying portion 17A that is long 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-shaped current-carrying portion 17A. Elongated current-carrying portions 17A, 17A substantially similar to the elongated current-carrying portion 39 described above are provided to extend along the outer surfaces 15a, 15a of both sides of the rail portion 15 of the upper frame 14A. These elongated current-carrying portions 17A, 17A are provided at the same height and have the same width.
