[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2005-194864 Summary of the Invention [Problem to be solved by the invention]

[0004] However, in the window door described in Patent Document 1, the solar cell module and the heating wire must be connected by electrical 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 fixture that allows for easy electrical connection between a panel portion including a solar cell module and a frame portion side. [Means for solving the problem]

[0006] In order to achieve the above-mentioned objective, the building fixture of the present disclosure comprises a panel portion including a solar cell module and a frame portion arranged to surround the four peripheral edges of the panel portion, and is characterized in that a power transmission portion for transmitting power generated by the solar cell module is provided on the outer periphery of the panel portion, and a power receiving portion for receiving power by contacting the power transmission portion is provided on the inner periphery of the frame portion. [Effects of the Invention]

[0007] The fitting according to the present disclosure has the above-described configuration, which makes it easy to electrically connect the panel portion including the solar cell module to the frame portion side. [Brief explanation of the drawings]

[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 a fitting according to this embodiment is installed.

[0010] 1 to 5 are diagrams that schematically show an example of a fitting according to this embodiment and a modified example thereof. 1(a) and 1(b), the fitting 1 according to this embodiment comprises a panel section 10 including a solar cell module 13, and a frame section 20 provided so as to surround the four periphery edges of the panel section 10. With this configuration, the solar cell module 13 of the fitting 1 can generate electricity. As shown in Figure 2(a), a power transmission unit 14 that transmits power generated by the solar cell module 13 is provided on the outer periphery of the panel unit 10, and a power receiving unit 17 that receives power by contacting the power transmission unit 14 is provided on the inner periphery of the frame unit 20. With this configuration, by assembling the panel unit 10 including the solar cell module 13 inside the frame unit 20, the power transmission unit 14 on the outer periphery comes into contact with the power receiving unit 17 on the inner periphery of the frame unit 20, enabling current to flow. This makes it easier to electrically connect the panel unit 10 to the frame unit 20 compared to a configuration that requires connecting electrical wiring, etc.

[0011] As shown in FIG. 1(b) and FIGS. 3(a)-(c), the fitting 1 includes a receiving base (vertical receiving base) 26 that is arranged between the outer peripheral end surface 10a of the panel unit 10 and the inner peripheral surface 20a of the frame unit 20 and that holds the electric wires 19 that transmit the power generated by the solar cell module 13. This configuration allows the electric wires 19 routed around the outer periphery of the panel unit 10 to be held, reducing the interference of the electric wires 19 when assembling the panel unit 10 and the frame unit 20, improving workability. Furthermore, by adjusting the thickness of the receiving base (vertical receiving base) 26 to fit the gap between the outer peripheral end surface 10a of the panel unit 10 and the inner peripheral surface 20a of the frame unit 20, dimensional variations in the panel unit 10 and the frame unit 20 can be accommodated, facilitating assembly. An example of the specific configuration of the receiving base (vertical receiving base) 26, the power transmission unit 14, and the power receiving unit 17 will be described later.

[0012] This fitting 1 may be installed in an appropriate fitting frame installed in an opening that penetrates a wall that separates the interior and exterior of a building. Such a fitting frame may be a rectangular frame with an upper frame, a lower frame, and left and right vertical frames, or may be fixed to an appropriate frame substrate such as a lintel, a window sill, or a pillar that separates the four sides of the opening. This fitting 1 may form a window device such as a waist-high window that extends from about waist height of an adult to a suitable height above the ceiling, or a bay window that extends from floor to a suitable height above the ceiling, or may even form a door device. This fitting 1 may form a movable window or door such as a bay window, a sliding window such as a double sliding window, a casement window such as an outward-opening or inward-opening casement window, a double-hung window, a tilting window such as an outward-opening or inward-opening window, or a draped window (tilts in and out), or even a fixed window.

[0013] As shown in FIGS. 1(a), 1(b), and 2(c), the panel portion 10 is rectangular. As shown in FIGS. 3(b) and 3(c), the panel portion 10 has a multi-layer structure having multiple (two in the illustrated example) light-transmitting plates 11, 11 in the thickness direction of the fixture. These light-transmitting plates 11, 11 may be glass plates or may be made of a synthetic resin material such as acrylic or polycarbonate. The light-transmitting plates 11, 11 are spaced apart in the thickness direction via appropriate spacers 12 formed in a roughly frame shape along their four peripheral edges. Additionally, an appropriate sealant may be provided around the outer periphery of the spacer 12 to seal a vacuum layer or a hollow space filled with various gases between the light-transmitting plates 11, 11.

[0014] The solar cell module 13 is provided along one surface in the thickness direction of one of the light-transmitting plates 11, 11 of the panel unit 10. This solar cell module 13 may be provided, for example, along the surface of the light-transmitting plate 11 on the outdoor side facing the outdoor side, or may be provided in another location. This solar cell module 13 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 11 or an appropriate substrate. Such thin-film solar cells may be, for example, perovskite solar cells that use a perovskite compound as a light-absorbing material, or other solar cells such as silicon solar cells. This solar cell module 13 has light-transmitting properties and may be provided over substantially the entire surface of one surface in the thickness direction of the light-transmitting plate 11 of the panel unit 10. The solar cell module 13 is provided with positive and negative electrodes that are electrically connected to the power transmission unit 14 .

[0015] As shown in Figures 1(a) and 1(b), the frame portion 20 is formed into a rectangular frame shape by an upper frame portion 22 and a lower frame portion 23, which are elongated in the left-right direction, and left and right vertical frame portions 24, 24, which are elongated in the up-down direction. The upper frame portion 22, the lower frame portion 23, and the vertical frame portions 24, 24 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. The upper frame portion 22, the lower frame portion 23, and the vertical frame portions 24, 24 may each be an extrusion molded product having a substantially uniform cross-sectional shape along its entire length. The upper frame portion 22, the lower frame portion 23, and the vertical frame portions 24, 24 may be joined to each other by suitable fasteners such as screws, welding, etc. In the illustrated example, the longitudinal ends of the upper and lower frame sections 22 and 23 are joined to the longitudinal ends of the left and right vertical frame sections 24, 24 in a so-called jointed manner, but the joints may also be joined in a vertical or horizontal manner.

[0016] As shown in Figure 3(b), panel receiving grooves 21 that receive the four peripheral edges of the panel section 10 are provided on the inner periphery of each of the upper frame section 22, the lower frame section 23, and the vertical frame sections 24, 24. The groove bottom surfaces of these panel receiving grooves 21 form the inner periphery 20a of the frame section 20. One side in the groove width direction of the panel receiving groove 21 is defined by an extension piece 28 that extends from one end of the inner periphery of each of the upper frame section 22, the lower frame section 23, and the vertical frame sections 24, 24 in the thickness direction of the fitting so as to cover the end of the panel section 10. The other side in the groove width direction of the panel receiving groove 21 is defined by a ledge member 29 attached to the other end of each of the upper frame section 22, the lower frame section 23, and the vertical frame sections 24, 24 in the thickness direction of the fitting. The extension piece 28 and the pressing edge member 29 are provided so as to extend around the entire periphery of the inner periphery of the frame portion 20. An appropriate gasket that comes into close contact with the panel portion 10 may be provided inside the panel receiving groove 21 so as to extend around almost the entire periphery. The panel receiving groove 21 that receives the four peripheral ends of the panel portion 10 is not limited to a configuration in which the other side in the groove width direction is defined by the pressing edge member 29 as in the example shown, and various other configurations may be used.

[0017] The upper stile portion 22, the lower stile portion 23, and the vertical stile portions 24, 24 may be provided with appropriate engaging portions or the like that engage with the fixture frame to which the fixture 1 is to be installed, depending on the type of the fixture 1, etc. For example, if the fixture 1 constitutes a sliding window, the upper stile portion 22 and the lower stile portion 23 may be provided with rail receiving grooves that receive rail portions provided on the upper and lower frames, and the lower stile portion 23 may be provided with appropriate door rollers, etc. Also, an appropriate handle portion may be provided in an appropriate location on the door end stile portion that is one of the left and right vertical stile portions 24, 24, and an appropriate locking device such as a crescent lock may be provided on the other door joint stile portion. The upper stile portion 22, the lower stile portion 23, and the vertical stile portions 24, 24 may be configured in various other ways depending on the type of the fixture 1, etc.

[0018] 2(a), in this example, one of the power transmitting unit 14 and the power receiving unit 17 is provided on a receiving stand (upper receiving stand) 16 disposed between the outer peripheral end surface 10a of the panel unit 10 and the inner peripheral surface 20a of the frame unit 20. This configuration can reduce poor contact between the power transmitting unit 14 and the power receiving unit 17 due to assembly errors, etc., compared to a configuration in which the outer peripheral end surface 10a of the panel unit 10 and the inner peripheral surface 20a of the frame unit 20 are assembled so that they abut or are close to each other over the entire circumference without providing such a receiving stand. Also, as described above, by adjusting the thickness of the receiving stand (upper receiving stand) 16 to fit into the gap between the outer peripheral end surface 10a of the panel unit 10 and the inner peripheral surface 20a of the frame unit 20, dimensional variations in the panel unit 10 and the frame unit 20 can be accommodated, and they can be easily assembled.

[0019] At least one of the power transmitting unit 14 and the power receiving unit 17 has a terminal 18 that is biased toward the other. With this configuration, electricity can be stably supplied even if there is an assembly error or the like. The power transmitting unit 14 is provided on the upper end side of the panel unit 10, and the power receiving unit 17 is provided on the upper frame portion 22 side of the frame portion 20. With this configuration, the power transmitting unit 14 and the power receiving unit 17 are located on the upper end side of the fitting 1, making them less susceptible to the effects of rainwater, etc. Specifically, as shown in Fig. 2(c), the panel unit 10 is provided with a pair of power transmission units 14, 14. One of these power transmission units 14, 14 may be electrically connected to the positive electrode of the solar cell module 13 via an appropriate electric wire or the like, and the other may be electrically connected to the negative electrode of the solar cell module 13 via an appropriate electric wire or the like.

[0020] These power transmitting sections 14, 14 are terminal sections 15, 15 formed to protrude upward from the outer peripheral end surface 10a of the panel section 10 toward the power receiving section 17 side. These terminal portions 15, 15 are arranged so as to be able to abut against a pair of power receiving portions 17, 17, respectively, as described below. In the illustrated example, these terminal portions 15, 15 are shown as being arranged at positions offset to one side in the left-right direction on the upper end surface constituting the outer peripheral end surface 10a of the panel portion 10, but this is not a limitation. Also, in the illustrated example, these terminal portions 15, 15 are arranged at the same circumferential position on the outer peripheral end surface 10a of the panel portion 10, spaced apart in the thickness direction of the fixture, but this is not a limitation. Also, these terminal portions 15, 15 are shown as having a truncated cone shape tapering upward, but this shape is not a limitation. These terminal portions 15, 15 may be formed from an appropriate metal or the like with good conductivity.

[0021] 2(a) and 2(b), a pair of power receiving parts 17, 17 are provided on the inner periphery of the frame part 20, which are in contact with the terminal parts 15, 15 that constitute the pair of power transmitting parts 14, 14, respectively. One of the pair of power receiving parts 17, 17 may be conducted to the positive electrode of the solar cell module 13 via one terminal part 15 or the like, and the other may be conducted to the negative electrode of the solar cell module 13 via the other terminal part 15 or the like. The fitting 1 may configure a solar power generation system by electrically connecting the power receiving parts 17, 17 to an appropriate power storage device or the like provided outside the fitting 1 via appropriate electric wires 19 or the like. In this example, these power receiving portions 17, 17 are terminal portions 18, 18 biased toward the terminal portions 15, 15 that constitute the power transmitting portions 14, 14. These terminal portions 18, 18 are provided on an upper receiving base 16 that is arranged between the downward-facing groove bottom surface that constitutes the inner peripheral surface 20a of the upper frame portion 22 and the upper end surface that constitutes the outer peripheral end surface 10a of the panel portion 10. An appropriate electric wire that is electrically connected to the power receiving portions 17, 17 and that is conductive to an electric wire 19 described below may be provided within this upper receiving base 16. This upper receiving base 16 is arranged within the panel receiving groove 21.

[0022] The upper support 16 is a rectangular plate with its thickness aligned vertically. The dimension of the upper support 16 in the thickness direction of the fixture corresponds to the width of the panel receiving groove 21 and may be smaller than the width of the panel receiving groove 21. The dimension of the upper support 16 in the longitudinal direction of the upper frame portion 22 (the left-right direction of the fixture) is smaller than the length of the upper frame portion 22, and may be, for example, approximately 20 mm to 200 mm or approximately 30 mm to 150 mm. In the illustrated example, the upper support 16 is positioned to one side in the left-right direction to correspond to the positions of the power transmission units 14, 14, but is not limited to this position. The upper support 16 may be fixed to the inner peripheral surface 20a of the upper frame portion 22 via adhesive, pressure-sensitive adhesive, or fasteners such as screws. In addition to the upper receiving base 16, a receiving base that does not have a similar upper receiving base 16 or a power receiving unit 17, 17 may be provided between the inner surface 20a of the upper frame portion 22 and the outer peripheral end surface 10a of the panel portion 10.

[0023] The terminal portions 18, 18 are provided so as to protrude downward from the inner circumferential side of the upper frame portion 22 (the underside of the upper receiving base 16) toward the power transmission unit 14 side. These terminal portions 18, 18 are provided at the same circumferential positions as the terminal portions 15, 15 that constitute the power transmission units 14, 14 described above, spaced apart in the thickness direction of the fixture, but are not limited to this example. These terminal portions 18, 18 have the same configuration, so one of them will be described below as an example. The terminal portion 18 includes a fixed piece 18a fixed to the upper receiving base 16 and a spring-like piece 18b connected to the fixed piece 18a and protruding downward. In its natural state (when not elastically deformed), the spring-like piece 18b extends obliquely downward from one end of the fixed piece 18a. The spring-like piece 18b is elastically deformable generally in the vertical direction. The spring-like piece 18b abuts against the terminal portion 15 as it elastically deforms. The dimension of the spring-like piece 18b in the thickness direction of the fixture may be greater than the dimension of the terminal portion 15 in the thickness direction of the fixture. The terminal portion 18 may be made of an appropriate metal or the like with good conductivity.

[0024] Terminal 18 is not limited to a configuration in which fixed piece 18a is provided with spring-like piece 18b in a cantilevered manner as shown in the illustration, but may have various other shapes such as a pantograph shape (diamond shape). Terminal 18 biased toward terminal 15 constituting power transmitting unit 14 is not limited to a configuration in which the contact portion with terminal 15 itself is spring-like piece 18b. Terminal 18 may have a configuration in which the contact portion with terminal 15 is biased by an appropriate spring or the like separate from the contact portion, allowing expansion and contraction in the generally vertical direction. For example, terminal 18 may include a pin-shaped electrode or an umbrella-shaped electrode biased in the vertical direction by a spring or the like. Instead of or in addition to terminal 18 constituting power receiving unit 17, terminal 15 constituting power transmitting unit 14 may be biased toward power receiving unit 17.

[0025] 3(a) to 3(c), in this example, a receiving groove 27 for receiving the electric wire 19 is provided in the receiving base (vertical receiving base) 26 having the function of holding the electric wire 19. With this configuration, the electric wire 19 can be held in the receiving groove 27 of the receiving base (vertical receiving base) 26. The receiving groove 27 is provided so as to open on the surface of the receiving base (vertical receiving base) 26 that faces outward in the thickness direction of the fixture. With this configuration, after the receiving base (vertical receiving base) 26 is fixed to the frame part 20 or the panel part 10, the electric wire 19 can be held in the receiving groove 27 of the receiving base (vertical receiving base) 26 from the outside in the thickness direction of the fixture, thereby improving workability. The width of the receiving groove 27 is smaller at the groove opening side than at the groove bottom side. With this configuration, it is possible to effectively reduce the risk of the electric wire 19 being unintentionally removed from the receiving groove 27.

[0026] 1(b) and 3(a), the receiving base (vertical receiving base) 26 is a vertical receiving base arranged between the groove bottom surface that forms the inner peripheral surface 20a of one vertical stile portion 24 and faces the other vertical stile portion 24, and the side end surface that forms the outer peripheral end surface 10a of the panel portion 10. This vertical receiving base 26 is arranged in the panel receiving groove 21, similar to the upper receiving base 16 described above. The vertical support base 26 is a rectangular plate with its thickness aligned with the left-right direction of the fixture. The dimension of the vertical support base 26 along the thickness direction of the fixture is set to correspond to the width of the panel receiving groove 21, similar to the upper support base 16 described above, and may be smaller than the width of the panel receiving groove 21. The dimension of the vertical support base 26 along the longitudinal direction (vertical direction) of the vertical stile 24 is smaller than the length of the vertical stile 24. For example, similar to the upper support base 16, the dimension may be approximately 20 mm to 200 mm or approximately 30 mm to 150 mm. While the vertical support base 26 is shown in the figure as being positioned off to one side in the vertical direction, this position is not limited. The vertical support base 26 may be fixed to the inner peripheral surface 20a of the vertical stile 24 via adhesive, pressure-sensitive adhesive, screws, or other fasteners.

[0027] The receiving groove 27 opens on the surface of the vertical receiving base 26 facing outward in the thickness direction of the fixture (either the outside or the inside of the room) and is provided so as to extend over the entire vertical receiving base 26 in the up-and-down direction (the same direction as the longitudinal direction of the vertical stile portion 24). As shown in FIG. 3(c), this receiving groove 27 is configured so as to be exposed when viewed in the thickness direction of the fixture when the batten member 29 that defines the other side of the panel receiving groove 21 in the groove width direction is removed. With this configuration, after assembling the panel portion 10 by fitting it into the stile portion 20 with the batten member 29 removed, the electric wire 19 can be easily held in the receiving groove 27 of the vertical receiving base 26.

[0028] The depth of the receiving groove 27 corresponds to the outer diameter of the electric wire 19. In the illustrated example, the width of the receiving groove 27 at the bottom corresponds to the sum of the outer diameters of the two electric wires 19. In other words, the receiving groove 27 is capable of receiving two electric wires 19. These electric wires 19 may be electrically connected to the pair of power receiving portions 17, respectively. The groove width dimension on the groove opening side of this receiving groove 27 may be slightly smaller than the combined outer diameter of the two electric wires 19, 19. The groove width dimension on the groove opening side of this receiving groove 27 may be an appropriate dimension from the viewpoint of improving the insertability and detachability of the electric wires 19, 19, and from the viewpoint of reducing unintentional detachment of the electric wire 19 from the receiving groove 27. Note that the configuration is not limited to one having a receiving groove 27 capable of receiving two electric wires 19, 19, and may be one having two receiving grooves 27 each receiving one of the two electric wires 19, 19.

[0029] 1(b), in addition to the upper receiving base 16 and the vertical receiving base 26, a lower receiving base 16A is provided on the inner periphery of the frame portion 20, which is disposed between the lower frame portion 23 and the lower end face of the panel portion 10, and a vertical receiving base 26A is provided between the other vertical frame portion 24 and the side end face of the panel portion 10. In other words, a receiving base is provided between each of the four peripheral end faces of the panel portion 10 and each of the upper frame portion 22, the lower frame portion 23, and the vertical frame portions 24, 24. The lower receiving base 16A is a rectangular plate-like member arranged with its thickness oriented in the vertical direction. In the illustrated example, the lower receiving base 16A is positioned to the other side in the left-right direction, opposite the upper receiving base 16, but the position is not limited to this. The vertical receiving base 26A is a rectangular plate-like member arranged so that its thickness is in the left-right direction of the fixture. In the illustrated example, the vertical receiving base 26A is positioned to the other side in the up-down direction, which is the opposite side from the vertical receiving base 26, but the position is not limited to this. As described above, the lower receiving base 16A and the vertical receiving base 26A may be fixed to the inner peripheral surfaces 20a of the lower stile portion 23 and the vertical stile portion 24 via adhesive, pressure-sensitive adhesive, screws, or other fasteners. A receiving groove 27 similar to that described above may be provided in both or one of the lower receiving base 16A and the vertical receiving base 26A. The upper receiving base 16, the lower receiving base 16A, and the vertical receiving bases 26, 26A on both sides may be made of resin, and may have a thickness selected from a plurality of different thicknesses to fit the gap between the outer peripheral end surface 10a of the panel portion 10 and the inner peripheral surface 20a of the stile portion 20.

[0030] Next, modified examples of the fittings will be described with reference to FIGS. 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.

[0031] 4(a) to 4(c) show a schematic view of a fitting 1A according to a first modified example. In this modification, the main difference from the above example is the configuration of power transmitting section 14A and power receiving section 17A. In this modification, power transmitting unit 14A is provided on the lower end side of panel unit 10A, and power receiving unit 17A is provided on the lower frame portion 23A side of frame portion 20A. With this configuration, power transmitting unit 14A at the lower end of panel unit 10A can be stably brought into contact with power receiving unit 17A on the lower frame portion 23A side by the weight of panel unit 10A. In this modification, one of power transmitting unit 14A and power receiving unit 17A is terminal unit 18A, and the other is circumferentially elongated current-carrying unit 15A. With this configuration, current can be stably passed even if there is an assembly error or the like.

[0032] Specifically, as shown in FIG. 4(a), elongated conductive portions 15A, 15A constituting a pair of power transmission units 14A, 14A are provided at the lower end of the panel unit 10A so as to extend in the circumferential direction, i.e., the left-right direction of the fixture. These elongated conductive portions 15A, 15A are provided at a distance in the thickness direction of the fixture on the lower end surface constituting the outer peripheral end surface 10a of the panel unit 10A. As described above, one of these elongated conductive portions 15A, 15A may be electrically connected to the positive electrode of the solar cell module 13 via an appropriate electric wire, and the other may be electrically connected to the negative electrode of the solar cell module 13 via an appropriate electric wire. These elongated conductive portions 15A, 15A have the same width. These elongated conductive portions 15A, 15A may be provided so as to extend across substantially the entire panel unit 10A in the left-right direction of the fixture. These long current-carrying portions 15A, 15A may be made of an appropriate metal or the like having good conductivity.

[0033] The terminal portions 18A, 18A constituting the pair of power receiving portions 17A, 17A are provided on a lower receiving base 16B arranged between the bottom surface of a groove facing upward that constitutes the inner peripheral surface 20a of the lower frame portion 23A and the lower end surface that constitutes the outer peripheral end surface 10a of the panel portion 10A. As described above, this lower receiving base 16B is a rectangular plate-like member arranged so that its thickness direction is the vertical direction. The terminals 18A, 18A are provided to protrude upward from the inner periphery of the lower frame portion 23A (the upper surface of the lower support 16B) toward the power transmission unit 14A. These terminals 18A, 18A are provided at the same circumferential positions as the elongated current-carrying portions 15A, 15A constituting the power transmission units 14A, 14A, and spaced apart in the thickness direction of the fixture, but this is not a limitation. In the illustrated example, the terminals 18A, 18A are frustum-shaped and tapered upward, but this shape is not a limitation. The terminals 18A, 18A may be formed from an appropriate metal or the like with good electrical conductivity.

[0034] In this modification, an example is shown in which power transmitting section 14A is configured as elongated current conducting section 15A, but instead of or in addition to this, power receiving section 17A may be configured as an elongated current conducting section or the like. In the above examples, the power transmitting unit 14, 14A is provided on the upper or lower end side of the panel unit 10, 10A, and the power receiving unit 17, 17A is provided on the upper frame 22 side or the lower frame 23A side, but this is not limited to this. For example, the power transmitting unit 14, 14A may be provided on one left-right end side of the panel unit 10, 10A, and the power receiving unit 17, 17A may be provided on one left-right vertical frame 24 side. In addition, in the above examples, the power receiving unit 17, 17A is provided on the receiving stand 16, 16B fixed to the frame portion 20, 20A side, but instead of this configuration, a configuration in which the power transmitting unit is provided on the receiving stand fixed to the panel portion 10, 10A side may be used. Furthermore, without providing such a receiving stand, a configuration in which the power transmitting unit on the outer periphery of the panel portion 10, 10A and the power receiving unit on the inner periphery of the frame portion 20, 20A are abutted against each other to be electrically connected.

[0035] FIG. 5(a) schematically shows a fitting 1B according to a second modified example. In this modified example, the main difference from the above example is the configuration of the vertical receiving base 26B. In this modified example, the receiving groove 27A of the vertical receiving base 26B is provided so as to open on the surface of the vertical receiving base 26B facing the inner peripheral surface 20a, which is on the side of the vertical frame portion 24. With this configuration, the vertical receiving base 26B is fixed along the inner peripheral surface 20a of the vertical frame portion 24 with the electric wire 19 held in the receiving groove 27A of the vertical receiving base 26B, whereby the electric wire 19 can be reliably held and unintentional detachment, etc. can be suppressed. In the illustrated example, the vertical receiving base 26B is provided with two receiving grooves 27A, 27A for respectively receiving two electric wires 19, 19. These receiving grooves 27A, 27A differ from the above-described receiving groove 27 in that the width dimension of the groove opening side is larger than the groove bottom side.

[0036] FIG. 5(b) schematically shows a fitting 1C according to a third modified example. In this modified example, the main difference from the above-described examples is the configuration of a vertical receiving stand 26C. In this modification, the vertical receiving base 26C is provided with an insertion hole 27B through which the electric wire 19 is inserted. With this configuration, although it is necessary to insert the electric wire 19 into the insertion hole 27B of the vertical receiving base 26C, the electric wire 19 can be securely held and unintentional detachment or the like can be suppressed. In the illustrated example, the vertical receiving base 26C is provided with two insertion holes 27B, 27B through which the two electric wires 19, 19 are respectively inserted. These insertion holes 27B, 27B are provided so as to penetrate the vertical receiving base 26C in the up-down direction.

[0037] FIG. 5(c) schematically shows a fitting 1D according to a fourth modified example. In this modified example, the main difference from the above-described examples is the configuration of the vertical frame portion 24A of the frame portion 20B and the vertical receiving base 26D. In this modified example, a receiving groove 25 that receives the electric wire 19 is provided in the vertical stile portion 24A, and the vertical receiving base 26D is arranged to close the opening of the receiving groove 25. With this configuration, the electric wire 19 can be reliably held by fixing the vertical receiving base 26D along the inner peripheral surface 20a of the vertical stile portion 24A with the electric wire 19 held in the receiving groove 25 of the vertical stile portion 24A, and unintentional detachment, etc. can be suppressed. In other words, in this modified example, the receiving groove 25 is provided in the vertical stile portion 24A, rather than being provided in the vertical receiving base 26D.

[0038] The receiving groove 25 of the vertical stile portion 24A opens at the inner peripheral surface 20a and is provided so as to extend in the longitudinal direction of the vertical stile portion 24A. This receiving groove 25 may be provided over substantially the entire length of the vertical stile portion 24A. This receiving groove 25 is capable of receiving two electric wires 19, 19. Furthermore, the width dimension of the receiving groove 25 on the groove opening side is smaller than that on the groove bottom side. In this modified example, a receiving groove 25 is provided in the vertical frame portion 24A, but instead of or in addition to this, a configuration in which a receiving groove that is blocked by a receiving base is provided in the upper frame portion 22 or the lower frame portion 23 may be used. Furthermore, the different configurations described in the above examples may be appropriately modified as needed, rearranged, or combined for application. The configuration of each member and each part of the fittings 1, 1A to 1D according to this embodiment is merely an example, and various other modifications are possible.
