[0010] [First prerequisite technology] Before describing the first embodiment of the present invention, a first underlying technology will be described below with reference to the drawings. As shown in the interior view of Figure 1, the fitting 9 of the first premise technology comprises a frame 2 that is attached to the wall of a building, etc., and a shoji screen 3 attached to the frame 2 so that the opening of the frame 2 can be opened and closed. The fitting 9 is a two-action (kidley) window that allows the shoji screen 3 to be opened and closed in two ways relative to the frame 2: opening inward and tilting inward.

[0011] The frame body 2 is formed by joining an upper frame 21, a lower frame 22, a left vertical frame 23, and a right vertical frame 24 in a rectangular shape. As shown in Figures 2 and 3, the upper frame 21, the lower frame 22, the left vertical frame 23, and the right vertical frame 24 are made of synthetic resin material with the same cross-sectional shape, and are formed by welding together the ends cut at an angle of 45° to the longitudinal direction.

[0012] The shoji screen 3 comprises a retaining frame 30 formed by joining an upper frame 31, a lower frame 32, a left vertical frame 33 and a right vertical frame 34 in a rectangular shape, a glass panel 35 as a surface material arranged within the retaining frame 30, and an upper ledge 36, a lower ledge 37, a left ledge 38 and a right ledge 39 attached to the upper frame 31, the lower frame 32, the left vertical frame 33 and the right vertical frame 34, respectively. The upper frame 31, lower frame 32, left vertical frame 33, and right vertical frame 34 are made of synthetic resin material with the same cross-sectional shape. The right vertical frame 34 is provided with a handle 40 that is operated when opening and closing the shoji screen 3. Each of the flanges 36, 37, 38, 39 is made of synthetic resin material of the same cross-sectional shape and includes flange bases 361, 371, 381, 391, mounting portions 362, 372, 382, ​​392 that are attached to the upper frame 31, lower frame 32, left vertical frame 33, and right vertical frame 34, respectively, and abutment portions 363, 373, 383, 393 that are provided on the exterior side of the flange bases 361, 371, 381, 391 and abut against the interior facing surface of the glass panel 35.

[0013] Airtightness and watertightness are ensured between the frame body 2 and the shoji screen 3 by airtight materials 25, 26 attached to the frame body 2 and airtight material 41 attached to the shoji screen 3. Airtight material 25 is attached to a retaining groove formed on the surface of the frame body 2 facing the exterior surface of the shoji screen 3. Airtight material 26 is attached to a retaining groove formed on the inner peripheral surface of the middle part of the frame body 2 in the projection direction. Airtight material 41 is attached to a retaining groove formed on the outer periphery of the shoji screen 3 facing the interior visible surface of the frame body 2.

[0014] As shown in Fig. 1, when the handle 40 of the fitting 9 is facing downward (0° direction), the fitting 9 is in a fully closed state with the shoji screen 3 locked. When the handle 40 is turned counterclockwise and facing horizontally (90° direction), the lower frame 32, which is the lower end of the shoji screen 3, is rotatably supported relative to the lower frame 22, and the fitting 9 is in an inward-tilting state where the shoji screen 3 is tilted toward the room. In the inward-tilting state, the opening and closing angle when fully open is restricted by a stay arm (not shown) provided between the upper frame 21 and the upper frame 31. Furthermore, when the handle 40 of the fitting 9 is turned further leftward and pointed upward (180°), the left vertical frame 33 is supported by the hinge 42 so as to be freely rotatable relative to the left vertical frame 23, and the shoji screen 3 is placed in an inward-opening state, opening toward the room. In the inward-opening state, an arm stopper (not shown) provided between the bottom frame 22 and the bottom frame 32 restricts the opening and closing angle of the shoji screen 3 when fully open to approximately 90°.

[0015] [First embodiment] Next, a first embodiment of the present invention will be described with reference to the drawings. As shown in Figures 3, 4 and 5, the first embodiment of the fitting 1 differs from the fitting 9 of the first base technology in that an upper batten 44 is provided instead of the upper batten 36, to which a curtain 43 can be attached as an inner layer constituting the covering member. The upper ledge 44 includes the ledge base 361, the attachment portion 362, and the contact portion 363 that the upper ledge 36 includes, and a curtain rail 441 as a covering member attachment portion. Curtain rail 441 is provided so as to protrude toward the interior of the room from the lower portion of ledge base 361. Curtain rail 441 has grooves 441A that hold multiple sliders 45 that hold curtains 43 so that they can move left and right. Curtain 43 is large enough to cover the entire visible surface of glass panel 35 on the interior side.

[0016] According to the first embodiment described above, the following effects can be achieved. (1) Since the curtain rail 441 is attached to the upper batten 44, if the curtain rail 441 is damaged, only the upper batten 44 needs to be replaced without replacing the upper frame 31, so the fitting 1 can be easily repaired. (2) When the curtain 43 is no longer needed, the upper batten 44 can be replaced with the upper batten 36 of the first base technology, thereby preventing a reduction in design quality due to the presence of an unnecessary curtain rail 441. (3) The curtain 43 can be made approximately the same size as the glass panel 35, that is, the minimum size necessary to conceal the interior of the room, and the amount of fabric used for the curtain 43 can be reduced. (4) The curtain 43 can be stored inside the shoji screen 3, and even if the shoji screen 3 is opened slightly for ventilation or airflow, the curtain 43 is prevented from being blown about by the wind or from interfering with ventilation or airflow. (5) Since the curtain rail 441 is provided on the upper edge 44, the shoji screen 3 can be half-opened without opening the curtain 43, allowing ventilation while viewing from a different angle. In contrast, if the curtain rail is provided on the upper frame 21, the curtain must be opened to allow ventilation, and ventilation while viewing from a different angle is not possible.

[0017] [Second prerequisite technology] Next, before describing the second embodiment of the present invention, a second underlying technology will be described with reference to the drawings. 6 and 7, the fitting 9A of the second base technology comprises a retaining frame 5 formed by joining an upper frame 51, a lower frame 52, a left vertical frame 53, and a right vertical frame 54 in a rectangular shape, a glass panel 6 as a surface material arranged within the retaining frame 5, and an upper batten 71, a lower batten 72, a left batten 73, and a right batten 74 attached to the upper frame 51, the lower frame 52, the left vertical frame 53, and the right vertical frame 54, respectively. The fitting 9A is a fixed window in which the glass panel 6 is held in an unopenable state by the retaining frame 5 and the upper batten 71, the lower batten 72, the left batten 73, and the right batten 74, and is attached to the wall of a building or the like.

[0018] The upper frame 51, the lower frame 52, the left vertical frame 53, and the right vertical frame 54 are made of synthetic resin material with the same cross-sectional shape. In the holding grooves formed on the surfaces of the upper frame 51, the lower frame 52, the left vertical frame 53, and the right vertical frame 54 facing the exterior facing surface of the glass panel 6, bead material 55, which is an airtight material that abuts against the exterior facing surface, is attached. Each flange 71, 72, 73, 74 is made of synthetic resin material of the same cross-sectional shape and includes a flange base 711, 721, 731, 741, mounting portions 712, 722, 732, 742 that are attached to the upper frame 51, lower frame 52, left vertical frame 53, and right vertical frame 54, respectively, and abutment portions 713, 723, 733, 743 that are provided on the exterior side of the flange base 711, 721, 731, 741 and abut against the interior facing surface of the glass panel 6.

[0019] [Second embodiment] Next, a second embodiment of the present invention will be described with reference to the drawings. As shown in Figures 7 and 8, the second embodiment of the fitting 1A differs from the fitting 9A of the second base technology in that it has an upper batten 75, instead of the upper batten 71, to which a curtain (not shown) can be attached as a covering member. The upper ledge 75 includes the ledge base 711, the attachment portion 712, and the contact portion 713 that the upper ledge 71 includes, and a curtain rail 751 as a covering member attachment portion. The curtain rail 751 is provided so as to protrude toward the interior of the room from the lower portion of the ledge base 711. The curtain rail 751 has a groove 751A that holds a plurality of sliders 45 that can move left and right and that hold a curtain similar to the curtain 43 of the first embodiment. The curtain is large enough to cover the entire visible surface of the glass panel 6 on the interior side.

[0020] According to the second embodiment described above, it is possible to achieve the same effects as those (1) to (3) of the first embodiment.

[0021] [Variations] In the first and second embodiments, a curtain is used as an example of the inner layer that constitutes the covering member, but a roll curtain, screen, blind, or the like may also be used as the inner layer, and a covering member mounting portion having a groove portion to which the inner layer can be attached may be provided on the upper ridges 44, 75. In the first and second embodiments, the ridges 44, 37, 38, 39, 75, 72, 73, and 74 may be provided on the outdoor side, so that a curtain serving as an outer layer constituting the covering member is positioned on the outdoor side. Also, a roller curtain, a screen, a blind, or the like may be used as the outer layer. If the covering member has a configuration that does not deform due to gravity, the covering member attachment portion may be provided on any one of the lower pressing edges 37, 72, the left pressing edges 38, 73, and the right pressing edges 39, 74. The cover member attachment portion may be provided on two or more of the upper ledges 36, 71, the lower ledges 37, 72, the left ledges 38, 73, and the right ledges 39, 74.

[0022] [Summary of the invention] The building fixture of the present invention comprises a retaining frame formed by framing the top, bottom, left and right frames, a panel placed within the retaining frame, and a ledge attached to each of the frames, and at least one of the ledges has a covering member attachment portion to which a covering member that covers at least a portion of the visible surface of the panel is attached. According to the present invention, if the covering member mounting portion is damaged, only the batten attached to the frame needs to be replaced, making it easy to repair the fixture.

[0023] In the fitting of the present invention, it is preferable that the covering member attachment portion has a groove portion into which the inner layer or outer layer serving as the covering member is attached. According to the present invention, the brightness inside a room can be easily adjusted by attaching an inner layer to the indoor side of the fixture and an outer layer to the outdoor side.
