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

[0002] BACKGROUND ART Conventionally, devices in which solar cells are incorporated into fittings such as doors have been known. 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 fitted. 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 frame located above the door.

[0004] However, with the door structure described in Patent Document 1, there is a concern that when the door is slid open, the output wiring and its connection parts connecting the solar cell to the battery inside the door may become exposed and easily touched.

[0005] The present disclosure has been made in consideration of the above-described circumstances, and aims to provide a fitting device that can prevent contact with a power receiving unit that receives power from a solar cell module. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the building fixture device of the present disclosure comprises a building fixture frame, and a building fixture that is arranged to slide freely within the building fixture frame and has a panel section that includes a solar cell module within the frame section, and is characterized in that one of the upper and lower frames of the building fixture frame has a power receiving section that receives power from the power transmitting section of the building fixture in a position that always overlaps with the building fixture that slides between a closed position and a fully open position in a plan view. [Effects of the Invention]

[0007] The fitting device according to the present disclosure is configured as described above, and thus can prevent contact with the power receiving section that receives power from the solar cell module. [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 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 comprises a fitting frame 10 and a fitting 20 having a panel section 21 slidably disposed within the fitting frame 10 and including a solar cell module 24 within a frame section 30. With this configuration, power can be generated in the solar cell module 24 of the fitting 20. As shown in FIG. 2, one of the upper frame 14 and lower frame 12 of the fitting frame 10 is provided with a power receiving unit 16 that receives power from a power transmitting unit 38 of the fitting 20 in a position that always overlaps, in a plan view, with the fitting 20 sliding between a closed position and a fully open position. With this configuration, the power receiving unit 16 on the fitting frame 10 side is always in a position where the fitting 20 sliding in the opening and closing direction is always present, thereby preventing unintentional contact with the power receiving unit 16.

[0011] In this embodiment, the power transmission unit 38 is provided in the upper frame 36 of the fitting 20, and the power receiving unit 16 is provided in the upper frame 14. With this configuration, the fitting 20 is less susceptible to the effects of rainwater, etc., compared to a configuration in which the power transmission unit is provided in the lower frame 33 and the power receiving unit is provided in the lower frame 12. 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.

[0012] In this embodiment, the door and window device 1 is equipped with two doors and windows 20, 20 arranged in a sliding manner within the door and window frame 10. These doors and windows 20, 20 are slidable along the longitudinal direction of rails 15, 13 provided on the upper and lower frames 14 and 12 of the door and window frame 10, and include an exterior door and window 20A arranged on the exterior (outdoor) side and an interior door and window 20B arranged on the interior (indoor) side within the door and window frame 10. The exterior door and window 20A and the interior door and window 20B have substantially the same configuration, and hereinafter, when there is no need to distinguish between the exterior door and window 20A and the interior door and window 20B, one of them will be described as the door and window 20. Furthermore, when there is no need to distinguish between the parts provided on the exterior and interior sides of the door and window frame 10 corresponding to the exterior door and window 20A and the interior door and window 20B, the terms "outdoor" and "indoor" will be omitted and the terms "outdoor" and "indoor" will be omitted.

[0013] 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.

[0014] 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.

[0015] The rail portion 15 of the upper frame 14 is provided so as to protrude from the lower surface 14a, which is the visible surface (the surface facing downward) of the upper frame 14, toward the lower frame 12, and to 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 outer rail portion 15A and the inner 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 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.

[0016] 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.

[0017] 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 facing 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.

[0018] 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.

[0019] 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.

[0020] The lower frame portion 33 is provided with a receiving groove 34 that receives the rail portion 13 of the lower frame 12. The receiving groove 34 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) 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.

[0021] 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.

[0022] The upper frame portion 36 is provided with a receiving groove 37 that receives the rail portion 15 of the upper frame 14. The receiving groove 37 is provided so as to open upward and to extend over substantially the entire length of the upper frame portion 36. 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.

[0023] A power transmission unit 38 is provided on at least one of the upper surfaces 36b, 36b on both sides of the opening width direction of the receiving groove 37 of the upper frame portion 36, and the power receiving unit 16 is provided opposite the power transmission unit 38. With this configuration, it is possible to reduce poor electrical conductivity due to the accumulation of dust and the like, compared to a configuration in which, for example, a power transmission unit is provided on the bottom side of the receiving groove 37 and a power receiving unit is provided on the underside of the rail portion 15 opposite it. The power transmitting unit 38 is an elongated current-carrying unit 39 that is elongated in the opening and closing direction of the fitting 20 (the longitudinal direction of the rail portion 15), and the power receiving unit 16 is a terminal portion 17 that receives power by contacting this elongated current-carrying unit 39. With this configuration, power can be passed by installing the fitting 20 so that the elongated current-carrying unit 39 contacts the terminal portion 17 on the fitting frame 10 side. This makes it easier to electrically connect the fitting 20 to the fitting frame 10 compared to a configuration that requires connecting output wiring, etc. Furthermore, power can be passed when the fitting 20 is opened or closed, or even in the open position, and power generated by the solar cell module 24 can be received more efficiently on the fitting frame 10 side compared to a configuration in which power is passed only in a predetermined position, such as the closed position.

[0024] 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.

[0025] Specifically, elongated current-carrying portions 39, 39 constituting a pair of power transmission portions 38, 38 are provided on each of the upper side surfaces 36b, 36b of the upper frame portion 36. The upper side surfaces 36b, 36b of the upper frame portion 36 form the upper end surfaces of the wall portions that partition both sides of the receiving groove 37 in the groove width direction, and are formed so as to be located at approximately the same height and to be approximately coplanar. One of these elongated current-carrying 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. As shown in Fig. 2, these elongated current-carrying portions 39, 39 have the same width. These elongated current-carrying portions 39, 39 may be provided so as to extend over substantially the entire length of the groove in the longitudinal direction. These elongated current-carrying portions 39, 39 may be formed from an appropriate metal or the like having good conductivity.

[0026] As shown in Figure 2, the power receiving unit 16 (terminal unit 17) is located in a position that overlaps with the door frame stile 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 located 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). This power receiving unit 16 (terminal unit 17) may be located in a position that overlaps with the door end stile 31 of the fitting 20 in the fully open position in a plan view, as shown by the two-dot chain line in Figure 2.

[0027] Specifically, terminal portions 17, 17 constituting a pair of power receiving portions 16, 16 are provided on both sides of the rail portion 15 on the underside 14a 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 an elongated 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 an elongated current-carrying portion 39 and an appropriate electric wire 25, etc. The door frame 10 may also 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.

[0028] 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, the terminal portions 17, 17 are arranged so that their lower ends are at the same height and have the same width along the projection direction. In the illustrated example, the terminal portions 17, 17 have a smaller width than the elongated conductive portions 39, 39, but they may be larger. The widths of the terminal portions 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 widths of the terminal portions 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.

[0029] 2 and 4(a), the terminal portion 17 includes a fixed piece portion 17a fixed along the lower surface 14a of the upper frame 14, and a spring-like piece portion 17b provided so as to be continuous with the fixed piece portion 17a and protruding downward from the lower surface 14a. Note that FIG. 2 illustrates a state in which the upper frame 14 is cut at a position where the terminal portion 17 will not be broken. Also, an example is shown in which an appropriate spacer is provided between the lower surface 14a of the upper frame 14, which is formed like an inclined surface, and the terminal portion 17 so that the lower ends of the terminal portions 17 are at the same height, but the present invention is not limited to this example. The terminal portion 17 has fixed pieces 17a on both sides of the spring pieces 17b in the longitudinal direction of the rail. Compared to a configuration in which the fixed pieces 17a are cantilevered, this configuration allows for stable contact with the elongated conductive portion 39 when the fixture 20 is opened and closed, and also prevents peeling. The spring pieces 17b are formed in a pantograph (diamond) shape. The spring pieces 17b include pieces that slope downward from the opposing ends of the fixed pieces 17a, and inclined pieces that slope downward from the ends of the separated inclined pieces and approach each other, with their tips connected. The tips of the spring pieces 17b abut against the elongated conductive portion 39 as the spring pieces 17b elastically deform.

[0030] 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 vertical 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 thereby expandable generally in the vertical direction. For example, the terminal 17 may include a pin-shaped electrode or an umbrella-shaped electrode biased in the vertical direction by a spring or the like.

[0031] In the above example, the terminal portions 17, 17 are provided in a position that overlaps the joint frame portion 32 of the fitting 20 in the closed position in a plan view, but this is not limited to this example and the terminal portions 17, 17 may be provided in other positions. The position at which the terminal portions 17, 17 are provided may be any position that always overlaps the fitting 20 that slides between the closed position and the fully open position in a plan view, and depending on the movable range of the fitting 20, the terminal portions 17, 17 may be provided so as to be located closer to the door edge than the joint frame portion 32 of the fitting 20 in the closed position.

[0032] Next, a modified example of the fitting device will be described with reference to FIG. 4(b) and FIGS. 5(a) and 5(b). 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.

[0033] FIG. 4(b) schematically shows a fitting device 1A according to a first modified example. In this modified example, the elongated current-carrying portions 39, 39 constituting the pair of power transmission portions 38, 38 are provided at intervals in the thickness direction of the fixture on the upper surface 36b on one side in the groove width direction of the receiving groove 37 of the upper frame portion 36A. In other words, in this modified example, no power transmission portion is provided on the upper surface 36b on the other side in the groove width direction of the receiving groove 37 of the upper frame portion 36A. The terminal portions 17, 17 that constitute a pair of power receiving portions 16, 16 are arranged spaced apart in the projection direction on one side of the rail portion 15 on the lower surface 14a of the upper frame 14A so that they can abut against these long-shaped current-carrying portions 39, 39.

[0034] FIG. 5(a) schematically shows a fitting device 1B according to a second modified example. In this modification, similarly to the example of FIG. 3, the elongated current-carrying portions 39, 39 constituting the pair of power transmission portions 38, 38 are provided on the upper surfaces 36b, 36b on both sides in the groove width direction of the receiving groove 37 of the upper frame portion 36. Each of the pair of power receiving portions 16A, 16A has a plurality of terminal portions 17, 17, 17, 17. With this configuration, it is possible to maintain a more stable energized state. The power receiving portion 16A on one side of the rail portion 15 on the underside 14a of the upper frame 14B in the projection direction has two terminal portions 17, 17 spaced apart in the projection direction, and the power receiving portion 16A on the other side in the projection direction has two terminal portions 17, 17 spaced apart in the projection direction.

[0035] FIG. 5(b) schematically shows a fitting device 1C according to a third modified example. In this modified example, a storage groove that opens at the upper end surface and extends the entire length is provided in each wall that defines both sides of the receiving groove 37 of the upper frame portion 36B in the groove width direction. The elongated current-carrying portions 39 that constitute a pair of power transmission units 38 are provided on the groove bottom surfaces 36Bb of the storage grooves, respectively. This configuration can more effectively prevent unintentional contact with the elongated current-carrying portions 39 than the configurations in which the elongated current-carrying portions 39 are provided on the upper surfaces 36b of the upper frame portions 36A, as in the above-described examples.

[0036] The terminals 17A, 17A constituting the pair of power receiving portions 16B, 16B of the upper frame 14C have an extendable pin structure. These terminals 17A, 17A include cylindrical holders 17Aa, 17Aa fixedly attached to the underside 14a of the upper frame 14C, and pin-shaped current-carrying portions 17Ab, 17Ab inserted into the cylindrical holders 17Aa so as to be able to move in and out. The pin-shaped current-carrying portions 17Ab, 17Ab are biased downward by biasing members such as springs provided within the cylindrical holders 17Aa, 17Aa. The pin-shaped current-carrying portions 17Ab, 17Ab are positioned so as to be able to abut against the elongated current-carrying portions 39, 39 of the upper frame portion 36B, respectively.

[0037] In this modification, the elongated conductive portions 39 are provided on the bottom surfaces 36Bb of the housing grooves, but they may be provided on the side surfaces of the housing grooves. In this case, the terminal portions 17A may be appropriately modified. Furthermore, the different configurations described in the above examples may be appropriately modified as needed, rearranged, or combined for application.

[0038] Furthermore, in the above examples, the elongated current-carrying portion 39 constituting the power transmitting portion 38 is provided on the upper surface 36b of the wall portion that defines both sides of the receiving groove 37 in the groove width direction, which are outside the receiving groove 37, or on the groove bottom surface 36Bb of the accommodation groove, but instead of this configuration, the elongated current-carrying portion 39 may be provided inside the receiving groove 37. For example, the elongated current-carrying portion 39 may be provided on the groove bottom surface that constitutes the inner surface of the receiving groove 37 or on one inner surface in the groove width direction. In this case, the terminal portion 17 constituting the power receiving portion 16 may be provided on the lower surface that constitutes the outer surface of the rail portion 15 or on the outer surface in the projection direction. The position of the power transmitting unit 38 provided on the upper frame portions 36, 36A, 36B is not limited to the above position and may be various other positions. Furthermore, the power receiving units 16, 16A, 16B may be provided at appropriate positions on the upper frames 14, 14A to 14C so as to be able to abut against the power transmitting unit 38 provided in various positions.

[0039] Furthermore, in the above examples, the terminal portion 17 is biased toward the long conductive portion 39, but it may be configured not to be biased. In addition, in each of the above examples, the power transmitting section 38 is an elongated current conducting section 39, and the power receiving sections 16, 16A, 16B are terminal sections 17, 17A, but both may be elongated current conducting sections or terminal sections, etc. Furthermore, in each of the above examples, the power transmission unit 38 is provided in the upper frame portion 36, 36A, 36B, and the power receiving units 16, 16A, 16B are provided in the upper frame 14, 14A to 14C. However, instead of this configuration, a power transmission unit 38 that is generally similar to the above may be provided in the lower frame portion 33, and power receiving units 16, 16A, 16B that are generally similar to the above may be provided in the lower frame 12. In each of the above examples, the fitting device 1, 1A to 1C is provided with two sliding fittings 20, 20, but it is also possible to have a configuration with three or more fittings, and one of the multiple fittings 20 may constitute a fixed window that cannot slide. The configuration of each member and each part of the fitting device 1, 1A to 1C according to this embodiment is merely an example, and various other modifications are possible.
