[Modes for carrying out the invention]

[0008] The embodiments of the building components described herein will be described below with reference to Figures 1 to 7. The embodiments described below represent one aspect of the disclosure and are not limiting, and can be modified at will within the scope of the technical concept of the disclosure. In addition, the scale of each component in the following drawings differs from that of the actual structure in order to make the components easier to understand.

[0009] The overall configuration of the joinery 1 will now be described. As shown in Figure 1, the joinery 1 comprises a rectangular frame 2 that is attached to an opening 1A formed in the wall of a building, sliding doors 10A and 10B that can slide horizontally on the frame 2, and a power supply device 30. The frame 2 has an upper frame 3, a lower frame 4, and left and right vertical frames 5, and is formed in the shape of a rectangular frame.

[0010] In the following, when a door or window 1 is installed in a building opening and viewed from the inside, the vertical direction is referred to as the vertical direction, and the horizontal direction as the horizontal direction. The direction perpendicular to the horizontal direction and aligned with the indoor / outdoor direction is called the depth direction. The depth direction corresponds to the first direction. The vertical direction corresponds to the second direction.

[0011] The joinery 1 has an outer shoji screen 10A and an inner shoji screen 10B housed inside the frame 2 in the depth direction, for opening and closing the opening 1A. The shoji screen 10A is on the exterior side and the shoji screen 10B is on the interior side, opening and closing the opening 1A horizontally. The shoji screens 10A and 10B are sliding shoji screens.

[0012] Shoji screens 10A and 10B each have an upper frame 11, a lower frame 12, and left and right vertical frames 13 and 14, and are formed in a rectangular frame shape. The vertical frame 13 in shoji screen 10A corresponds to the door-edge frame located on the door-edge side of shoji screen 10A. In the following description, the vertical frame 13 in shoji screen 10A will be referred to as the door-edge frame 13. Glass, for example, is housed inside shoji screens 10A and 10B.

[0013] The power supply device 30 includes a frame-side device 30A and a sliding door-side device 30B. The frame-side device 30A is installed inside the left vertical frame 5 of the frame body 2. The vertical frame 5 corresponds to the frame body 2. The sliding door-side device 30B is installed inside the door frame 13. The power supply device 30 supplies power from the frame-side device 30A to the sliding door-side device 30B.

[0014] As shown in Figures 2 and 3, the frame-side device 30A includes a first link mechanism 50A, a power supply side electrode 31A, a first shielding portion 32A, and a first protruding portion 33A.

[0015] The first link mechanism 50A moves the power supply electrode 31A to the opposite side of the direction of movement of the first protrusion 33A as the first protrusion 33A moves in the opposite direction. The first link mechanism 50A includes a fixed plate 51A, a first guide portion 52A, a guide shaft 53A, a guide shaft 54A, a movable portion 55A, a movable portion 56A, a movable portion 57A, a joint 58A, a joint 59A, a joint 60A, a link 61A, and a link 62A.

[0016] The fixing plate 51A is a rectangular plate extending vertically and is fixed to the inner surface on the left side of the vertical frame 5. The first guide portion 52A is a rectangular plate extending from the top to the right side of the fixing plate 51A in an opposing direction. The right end of the first guide portion 52A is separated from the inner surface on the right side of the vertical frame 5 with a gap between them. The guide shaft 53A is a rectangular prism extending from the bottom to the right side of the fixing plate 51A in an opposing direction. The guide shaft 54A is a semi-cylindrical shape extending vertically. The upper end of the guide shaft 54A is connected to the lower surface of the right end of the first guide portion 52A. The lower end of the guide shaft 54A is connected to the right end of the guide shaft 53A.

[0017] The moving part 55A is arranged above the first guide part 52A. A columnar joint 58A extending in the expected direction is inserted through the moving part 55A. The moving part 55A is rotatable with respect to the joint 58A. Although details will be described later, the moving part 55A is movable in the opposite direction along the upper surface of the first guide part 52A.

[0018] A guide shaft 53A is inserted through the moving part 56A. The moving part 56A is guided by the guide shaft 53A and is movable in the opposite direction. Since the guide shaft 53A is quadrangular prism-shaped, the moving part 56A is non-rotatable with respect to the guide shaft 53A. A columnar joint 59A extending in the expected direction is inserted through the moving part 56A. The moving part 56A is rotatable with respect to the joint 59A.

[0019] A guide shaft 54A is inserted vertically through the moving part 57A. The moving part 57A is guided by the guide shaft 54A and is movable in the vertical direction. Since the guide shaft 54A is quadrangular prism-shaped, the moving part 57A is non-rotatable with respect to the guide shaft 54A. A columnar joint 60A extending in the expected direction is inserted through the moving part 57A. The moving part 57A is rotatable with respect to the joint 60A.

[0020] The link 61A has its ends rotatably connected to the joint 58A and the joint 60A respectively. The link 62A has its ends rotatably connected to the joint 59A and the joint 60A respectively.

[0021] In the first link mechanism 50A of the embodiment, when the moving part 56A is guided by the guide shaft 53A and moves to the left together with the joint 59A and the link 62A, the moving part 57A is guided by the guide shaft 54A and moves downward together with the joint 60A and the link 62A. When the moving part 57A is guided by the guide shaft 54A and moves downward together with the joint 60A and the link 62A, the moving part 55A is guided by the upper surface of the first guide part 52A and moves to the right together with the joint 58A and the link 61A.

[0022] In the first link mechanism 50A of the embodiment, when the moving part 56A is guided by the guide shaft 53A and moves to the right together with the joint 59A and the link 62A, the moving part 57A is guided by the guide shaft 54A and moves upward together with the joint 60A and the link 62A. When the moving part 57A is guided by the guide shaft 54A and moves upward together with the joint 60A and the link 62A, the moving part 55A is guided by the upper surface of the first guide part 52A and moves to the left together with the joint 58A and the link 61A. The downward movement of the moving part 55A is restricted by the first guide part 52A, but it can move upward in the opposite direction with freedom.

[0023] The power supply side electrode 31A is provided inside the vertical frame 5. The power supply side electrode 31A has a rectangular parallelepiped shape extending in the left - right direction. The power supply side electrode 31A is provided facing the first opening 5a formed on the first facing surface 21 of the frame body 2 facing the shoji 10A. The vertical dimension and the prospective dimension of the power supply side electrode 31A are each shorter than the vertical dimension and the prospective dimension of the first opening 5a. The power supply side electrode 31A can project from the first opening 5a when it moves to the right. The power supply side electrode 31A faces the shoji 10A in the left - right direction through the first opening 5a. The left - right direction corresponds to the facing direction. The power supply side electrode 31A is connected and fixed above the moving part 55A. The power supply side electrode 31A can move in the opposite direction with freedom upward as the moving part 55A moves.

[0024] As shown in Figure 4, the power supply side electrode 31A has a plug 40 and a magnet part 41. Two plugs 40 are arranged spaced apart in the depth direction. The plugs 40 protrude to the right. The plugs 40 are power supply terminals. The magnet part 41 is embedded in the right side surface of the power supply side electrode 31A. The magnet part 41 is positioned between the two plugs 40 on the power supply side electrode 31A.

[0025] The first shielding portion 32A is provided inside the vertical frame 5 and is movable vertically between a position that shields the first opening 5a and a position that leaves it open. The first shielding portion 32A is a rectangular plate that extends vertically. The first shielding portion 32A is movable along the wall surface through which the first opening 5a opens. The first shielding portion 32A is connected to the movable portion 57A from the right side at its lower end. The first shielding portion 32A is movable vertically in conjunction with the movement of the movable portion 57A.

[0026] The first projection 33A is provided inside the vertical frame 5 and is movable in the opposing direction. The first projection 33A is a rectangular parallelepiped extending in the left-right direction. The first projection 33A is formed on the first opposing surface 21 and is provided opposite the third opening 5b, which is different from the first opening 5a. The vertical dimension and depth dimension of the first projection 33A are shorter than the vertical dimension and depth dimension of the third opening 5b, respectively. When the first projection 33A is moved to the right, it can protrude from the third opening 5b. The first projection 33A faces the shoji screen 10A in the left-right direction via the third opening 5b.

[0027] The first projection 33A has an engaging portion 63A that protrudes around its entire circumference midway in the opposing direction. The vertical and depth dimensions of the engaging portion 63A are shorter than the vertical and depth dimensions of the third opening 5b. When the first projection 33A moves to the right and protrudes from the third opening 5b, the engaging portion 63A engages with the vertical frame 5. The first projection 33A is connected to the movable portion 56A from below on its upper side. The first projection 33A is movable in the opposing direction as the movable portion 56A moves.

[0028] A first biasing member 64A is provided on the left side of the first protrusion 33A. The first biasing member 64A is positioned between the fixing plate 51A and the first protrusion 33A. The first biasing member 64A is, for example, a compression spring. The first biasing member 64A biases the first protrusion 33A from the left side in a direction that causes the first protrusion 33A to protrude from the third opening 5b. In Figure 3, the illustration of the first biasing member 64A is omitted.

[0029] The shoji-side device 30B includes a second link mechanism 50B, a power receiving electrode 31B, a second shielding portion 32B, and a second protruding portion 33B.

[0030] The second link mechanism 50B moves the power receiving electrode 31B to the opposite side of the direction of movement of the second protrusion 33B as the second protrusion 33B moves in the opposite direction. The second link mechanism 50B includes a fixed plate 51B, a second guide portion 52B, a guide shaft 53B, a guide shaft 54B, a movable portion 55B, a movable portion 56B, a movable portion 57B, a joint 58B, a joint 59B, a joint 60B, a link 61B, and a link 62B.

[0031] The fixing plate 51B is a rectangular plate extending vertically and is fixed to the inner surface on the right side of the vertical frame 13. The second guide portion 52B is a semi-cylindrical shape extending from the top to the left of the fixing plate 51B in an opposing direction. The left end of the second guide portion 52B is separated from the inner surface on the left side of the vertical frame 13 with a gap between them. The guide shaft 53B is a rectangular prism shape extending from the bottom to the left of the fixing plate 51B in an opposing direction. The guide shaft 54B is a semi-cylindrical shape extending vertically. The upper end of the guide shaft 54B is connected to the lower side of the left and right ends of the second guide portion 52B. The lower end of the guide shaft 54B is connected to the left end of the guide shaft 53B.

[0032] The movable part 55B is positioned above the second guide part 52B. A cylindrical joint 58B extending in the depth direction is inserted through the movable part 55B. The movable part 55B is rotatable relative to the joint 58B. The movable part 55B is movable in the opposite direction along the second guide part 52B.

[0033] A guide shaft 53B is inserted through the movable part 56B. The movable part 56B is guided by the guide shaft 53B and can move in the opposite direction. Since the guide shaft 53B is rectangular prism-shaped, the movable part 56A cannot rotate relative to the guide shaft 53B. A cylindrical joint 59B extending in the depth direction is inserted through the movable part 56B. The movable part 56B is rotatable relative to the joint 59B.

[0034] A guide shaft 54B is inserted vertically through the movable part 57B. The movable part 57B is movable vertically, guided by the guide shaft 54B. Because the guide shaft 54B is rectangular in shape, the movable part 57B cannot rotate relative to the guide shaft 54B. A cylindrical joint 60B extending in the depth direction is inserted through the movable part 57B. The movable part 57B is rotatable relative to the joint 60B.

[0035] Link 61B is rotatably connected at its ends to joints 58B and 60B, respectively. Link 62B is rotatably connected at its ends to joints 59B and 60B, respectively.

[0036] In the second link mechanism 50B of the embodiment, when the movable part 56B is guided by the guide shaft 53B and moves to the right together with the joint 59B and link 62B, the movable part 57B is guided by the guide shaft 54B and moves downward together with the joint 60B and link 62B. When the movable part 57B is guided by the guide shaft 54B and moves downward together with the joint 60B and link 62B, the movable part 55B is guided by the second guide part 52B and moves to the left together with the joint 58B and link 61B.

[0037] In the second link mechanism 50B of this embodiment, when the movable part 56B is guided by the guide shaft 53B and moves to the left together with the joint 59B and link 62B, the movable part 57B is guided by the guide shaft 54B and moves upward together with the joint 60B and link 62B. When the movable part 57B is guided by the guide shaft 54A and moves downward together with the joint 60A and link 62A, the movable part 55B is guided by the second guide part 52B and moves to the right together with the joint 58B and link 61B.

[0038] The receiving electrode 31B is provided inside the door frame 13. The receiving electrode 31B is a rectangular parallelepiped extending in the left-right direction. The receiving electrode 31B is provided facing a second opening 13a formed on the second opposing surface 22 of the door frame 13 that faces the frame 2. The vertical and depth dimensions of the receiving electrode 31B are shorter than the vertical and depth dimensions of the second opening 13a. The receiving electrode 31B can protrude from the second opening 13a when moved to the left. The receiving electrode 31B faces the frame 2 in the opposite direction via the second opening 13a. The receiving electrode 31B is connected to and fixed to the upper side of the movable part 55B. The receiving electrode 31B can move in the opposite direction as the movable part 55B moves.

[0039] As shown in Figure 4, the receiving electrode 31B has two insertion holes 42 located opposite the plug 40. The plug 40 is inserted into the insertion holes 42 when the supplying electrode 31A and the receiving electrode 31B come into contact. Power is supplied from the supplying electrode 31A to the receiving electrode 31B when the plug 40 is inserted into the insertion holes 42. The receiving electrode 31B has a magnetic portion 43 positioned between the insertion holes 42 in the depth direction. The magnetic portion 43 is made of a magnetic material. The magnetic portion 43 is, for example, a steel plate. The magnetic portion 43 is provided on the surface of the receiving electrode 31B that faces the supplying electrode 31A.

[0040] The second shielding portion 32B is provided inside the door frame 13 and is movable vertically between a position that shields the second opening 13a and a position that leaves it open. The second shielding portion 32B is a rectangular plate that extends vertically. The second shielding portion 32B is movable along the wall surface through which the second opening 13a opens. The second shielding portion 32B is connected to the movable portion 57B from the left side at its lower end. The second shielding portion 32B is movable vertically in conjunction with the movement of the movable portion 57B.

[0041] The second projection 33B is located inside the door frame 13 and is movable in the opposing direction. The second projection 33B is a rectangular parallelepiped extending in the left-right direction. The second projection 33B is formed on the second opposing surface 22 and is located opposite the fourth opening 13b, which is different from the second opening 13a. The vertical and depth dimensions of the second protrusion 33B are shorter than the vertical and depth dimensions of the fourth opening 13b. The second protrusion 33B can protrude from the fourth opening 13b when moved to the left. The second protrusion 33B faces the frame 2 in the opposite direction through the fourth opening 13b.

[0042] The second projection 33B has an engaging portion 63B that protrudes around its entire circumference midway in the opposing direction. The vertical and depth dimensions of the engaging portion 63B are shorter than the vertical and depth dimensions of the fourth opening 13b, respectively. When the second projection 33B moves to the left and protrudes from the fourth opening 13b, the engaging portion 63B engages with the door frame 13. The second projection 33B is connected to the movable portion 56B from below on its upper side. The second projection 33B is movable in the opposing direction as the movable portion 56B moves.

[0043] A second biasing member 64B is provided to the right of the second protrusion 33B. The second biasing member 64B is positioned between the fixing plate 51B and the second protrusion 33B. The second biasing member 64B is, for example, a compression spring. The second biasing member 64B biases the second protrusion 33B from the right side in a direction that causes it to protrude from the fourth opening 13b. In Figure 3, the second biasing member 64B is not shown.

[0044] In the embodiment of the door 1, before the sliding door 10A is separated from the vertical frame 5 of the frame 2 and closed, the first biasing member 64A biases the first projection 33A from the left side on the vertical frame 5, causing the first projection 33A to move to the right side, as shown in Figure 2. When the first projection 33A moves to the right side, the operation of the first link mechanism 50A positions the first shielding portion 32A to shield the first opening 5a, and the power supply side electrode 31A is positioned inside the vertical frame 5. In the embodiment of the door 1, before the sliding door 10A is separated from the vertical frame 5 of the frame 2 and closed, the second biasing member 64B biases the second projection 33B from the right side on the door frame 13, causing the second projection 33B to move to the left side. When the second protrusion 33B moves to the left, the operation of the second link mechanism 50B positions the second shielding portion 32B to shield the second opening 13a, the receiving electrode 31B is positioned inside the door frame 13, and it becomes a non-powered position where no power is supplied from the supplying electrode 31A to the receiving electrode 31B.

[0045] In the embodiment of the door 1, when the sliding door 10A closes against the vertical frame 5 of the frame 2, the tip of the first projection 33A protruding from the vertical frame 5 and the tip of the second projection 33B protruding from the door frame 13 come into contact. When the sliding door 10A is closed, as shown in Figure 5, the first projection 33A moves to the left and the second projection 33B moves to the right, so that the tip surfaces of the first projection 33A and the second projection 33B become flush with the first opposing surface 21 and the second opposing surface 22.

[0046] When the first protrusion 33A moves to the left, the operation of the first link mechanism 50A causes the first shielding portion 32A and the power supply side electrode 31A to move synchronously and integrally. The first shielding portion 32A is positioned to open the first opening 5a. The power supply side electrode 31A is positioned in the power supply position. When the second protrusion 33B moves to the right, the operation of the second link mechanism 50B causes the second shielding portion 32B and the power receiving side electrode 31B to move synchronously and integrally. Due to the synchronous movement, the first shielding portion 32A is positioned to open the first opening 5a, and the second shielding portion 32B is positioned to open the second opening 13a, the power supply side electrode 31A and the power receiving side electrode 31B come into contact, and the plug 40 is inserted into the insertion hole 42 to supply power, resulting in the power supply position.

[0047] When the shoji screen 10A is closed, the relative positional relationship between the power supply electrode 31A and the power receiving electrode 31B may shift due to construction errors or other reasons. If the power supply electrode 31A and the power receiving electrode 31B approach each other while their relative positions are misaligned, the magnetic force between the magnet part 41 and the magnetic part 43 will pull them together, allowing the relative positional relationship to be adjusted.

[0048] In the building fixture 1 of this embodiment, when the sliding door 10A is open, the first shielding part 32A shields the first opening 5a and the second shielding part 32B shields the second opening 13a, thereby suppressing deterioration due to water exposure and humidity.

[0049] In the building component 1 of this embodiment, the power supply side electrode 31A and the power receiving side electrode 31B do not come into contact with other parts except when power is being supplied, thus suppressing deterioration and failure due to friction.

[0050] In the building fixture 1 of the embodiment, the magnetic force between the magnet part 41 and the magnetic part 43 attracts the power supply side electrode 31A and the power receiving side electrode 31B to adjust their relative positional relationship. Furthermore, since the power supply side electrode 31A has a degree of freedom in the vertical direction and can move in the opposing direction, it becomes possible to absorb misalignments caused by building errors and the like and supply power smoothly.

[0051] Preferred embodiments of this disclosure have been described above with reference to the attached drawings, but it goes without saying that this disclosure is not limited to these examples. The shapes and combinations of the components shown in the above examples are just examples and can be modified in various ways based on design requirements, etc., without departing from the spirit of this disclosure.

[0052] In the embodiment of the building component 1, a configuration in which the power supply side electrode 31A can move in the opposite direction with a degree of freedom in the vertical direction was illustrated, but the invention is not limited to this configuration. For example, a configuration in which the power supply side electrode 31A can move in the opposite direction with a degree of freedom in the depth direction, and a configuration in which the power supply side electrode 31A can move in the opposite direction with a degree of freedom in both the vertical and depth directions may be adopted. For example, one of the following configurations may be selected: a configuration in which the power supply side electrode 31A is constrained to move in the vertical and depth directions and the power receiving side electrode 31B can move in the opposite direction with a degree of freedom in the vertical direction, a configuration in which it can move in the opposite direction with a degree of freedom in the depth direction, and a configuration in which it can move in the opposite direction with a degree of freedom in both the vertical and depth directions.

[0053] In the embodiment of the building component 1, a configuration in which the power supply side electrode 31A has a magnetic part 43 and the power receiving side electrode 31B has a magnet part 41 was illustrated, but the invention is not limited to this configuration. For example, the power supply side electrode 31A may have a magnet part 41 and the power receiving side electrode 31B may have a magnetic part 43. Both the power supply side electrode 31A and the power receiving side electrode 31B may have magnet parts with different magnetic poles.

[0054] In the embodiment of the door fitting 1, the frame-side device 30A is provided inside the vertical frame 5 and the sliding door-side device 30B is provided inside the door frame 13 as an example, but the invention is not limited to this configuration. For example, the frame-side device 30A may be provided on either the upper frame 3 or the lower frame 4, and the sliding door-side device 30B may be provided on either the upper frame 11 or the lower frame 12 facing the frame-side device 30A.

[0055] Figure 6 shows a modified configuration in which the frame-side device 30A is provided on the upper frame 3 and the sliding door-side device 30B is provided on the upper frame 11. The sliding door 10A closes by moving to the left, as indicated by the arrow in the figure, relative to the upper frame 3. The first projection 33A has an inclined surface 35A at its lower end that slopes downward as it moves to the left. The second projection 33B has an inclined surface 35B at its upper end that slopes downward as it moves to the left and is parallel to the inclined surface 35A.

[0056] As shown in Figure 7, when the sliding door 10A is closed, the inclined surface 35A and the inclined surface 35B come into contact, causing the first protrusion 33A to move upward and the second protrusion 33B to move downward. When the first protrusion 33A moves upward, the operation of the first link mechanism 50A causes the power supply side electrode 31A to move downward, and the operation of the second link mechanism 50B causes the power receiving side electrode 31B to move upward, allowing the power supply side electrode 31A and the power receiving side electrode 31B to be positioned in contact, thus obtaining the same operation and effect as the joinery 1 shown in the embodiment.

[0057] In the modified joinery, even if the direction of movement of the power supply side electrode 31A and the power receiving side electrode 31B during power supply intersects with the opening and closing direction of the sliding door 10A, the first protrusion 33A and the second protrusion 33B are the parts that come into contact with and rub against other parts in the power supply device 30 when the sliding door 10A is opened and closed. Since the first protrusion 33A and the second protrusion 33B are not directly involved in power supply, it is possible to suppress them from causing malfunctions in the power supply device 30.
