Description

The present invention relates to a fixture that includes an inner and outer shoji screen, which are linked up and down in opposite directions by a cord-like object such as a wire that connects them.

Fittings that allow the inner and outer shoji screens to move up and down include those in which the ends of a rope-like body such as a wire are connected to each shoji screen, and the middle part of the rope-like body is wrapped around a reversing element such as a pulley attached to the vertical frame. With this type of fitting, for example, when the inner shoji screen is moved upward, the outer shoji screen is moved downward via the rope-like body, which has the advantage of improving the ease of opening and closing the shoji screens (see, for example, Patent Documents 1 and 2).

However, the vertical stiles that act as guides when moving the shoji screen relative to the frame are always covered by the frame. Therefore, it becomes difficult to connect a rope to the middle of the vertical stile after the shoji screen has been installed in the frame. Meanwhile, the connection position of the rope to the shoji screen needs to be set below the reversal element. Therefore, to simplify the task of connecting the rope to the shoji screen, it is preferable to connect the rope to the lower end of each shoji screen. However, this type of fitting requires a rope that is longer than the overall height of the shoji screen. As a result, a different type of rope is required depending on the overall height of the shoji screen, which can be a limitation when trying to reduce the manufacturing costs of the fitting.

In light of the above situation, the present invention aims to provide building materials that can reduce manufacturing costs.

To achieve the above objective, the fittings of the present invention comprise an inner and outer shoji screen mounted on a frame made up of left and right vertical frames and top and bottom horizontal frames all around. The inner and outer shoji screens are linked together by a rope-like member hanging down via a reversing element attached to the vertical frames, allowing them to move vertically in opposite directions. One of the inner and outer shoji screens has a guide groove extending vertically on the projecting surface facing the vertical frames, as well as a stopper member, and one end of the rope-like member has an abutment member that is inserted into the guide groove from the bottom and abuts against the stopper member.

According to this invention, the abutment member inserted into the guide groove abuts against the stopper member, connecting the cord to the shoji screen. Therefore, by providing the stopper member at a position higher than the bottom edge of the shoji screen, even when the abutment member is inserted from the bottom edge of the guide groove, the cord can be connected to a position higher than the bottom edge. This allows the inner and outer shoji screens to be connected to each other by the cord after being installed into the frame, simplifying manufacturing. Furthermore, by adjusting the mounting position of the stopper member, it becomes possible to use a common cord for fittings with shoji screens of different overall heights, for example, and this allows for the sharing of parts, thereby reducing manufacturing costs.

Below, preferred embodiments of the fittings according to the present invention will be described in detail with reference to the accompanying drawings. Note that, for convenience, the terms "prospect direction" and "visibility direction" will sometimes be used below. The prospect direction is the direction along the depth of the fitting, as indicated by arrow A in the figure. A surface along the prospect direction will sometimes be referred to as a "visibility surface." The prospect direction is the direction perpendicular to the prospect direction for items that extend horizontally, such as sill frames. For items that extend vertically, such as vertical frames, the horizontal direction perpendicular to the prospect direction is called the "visibility direction." A surface along the prospect direction will sometimes be called a "visibility surface."

Figures 1 to 6 show a fixture that is an embodiment of the present invention. The fixture illustrated here is used as a back door and includes an opening frame 1 and a door panel 2. The opening frame 1 is constructed by assembling an upper opening frame 1A, a lower opening frame 1B, and left and right vertical opening frames 1C around all four sides. The door panel 2 is constructed by a door frame body (frame body) 10 and two ventilation shoji screens 20A and 20B, and is supported so as to be openable and closable relative to the opening frame 1 by means of a hinge 3 interposed between the door frame body 10 and one of the vertical opening frames 1C. The opening frame 1 is constructed by a composite structure including a metal opening frame portion 1m molded from a metal such as an aluminum alloy and a resin opening frame portion 1p molded from a resin, and is attached to the building frame with the metal opening frame portion 1m facing outward. The metal opening frame 1m and the resin opening frame 1p are extruded members, each configured so that the cross-sectional shape is approximately uniform over the entire length along its longitudinal axis.

The door frame 10 is made up of a four-sided framework consisting of an upper door frame (horizontal frame) 11, a lower door frame (horizontal frame) 12, and left and right vertical door frames (vertical frames) 13, 14. The upper door frame 11, lower door frame 12, and vertical door frames 13, 14 are composite frames made of a metal frame section formed from a metal such as an aluminum alloy and a resin frame section formed from a resin, and are supported by the opening frame 1 with the metal frame section facing the exterior. The metal frame section and the resin frame section are extruded shapes, and each is configured so that the entire longitudinal length has a substantially uniform cross-sectional shape.

The metal frame portion 11A of the upper door frame 11 is formed by integrally molding the upper door frame base 11A1 and the upper door support wall portion 11A2. The upper door frame base 11A1 is hollow and has a vertically elongated, approximately rectangular cross section. A resin frame portion 11B is attached to this upper door frame base 11A1 so as to cover almost the entire visible surface facing the interior of the vehicle. Furthermore, an upper frame extension member 11C molded from resin is provided on the inner peripheral surface of the upper door frame base 11A1 and the resin frame portion 11B so as to protrude toward the interior of the vehicle. The upper door support wall portion 11A2 is a thin plate that extends almost horizontally from the inner peripheral portion of the visible surface facing the exterior of the upper door frame base 11A1 toward the exterior, and then bends at an approximately right angle toward the inner peripheral side.

The metal frame portion 12A of the lower door frame 12 is formed by integrally molding the lower door frame base 12A1, lower door boundary wall portion 12A2, lower door inner peripheral wall portion 12A3, and lower door support wall portion 12A4. Like the upper door frame base 11A1, the lower door frame base 12A1 is hollow and has a vertically elongated, approximately rectangular cross section. The dimensions of the lower door frame base 12A1 along the front and rear directions are approximately the same as those of the upper door frame base 11A1. A resin frame portion 12B is attached to the lower door frame base 12A1 so as to cover almost the entire front surface facing the interior of the vehicle. The lower door boundary wall portion 12A2 is a thin plate-like member that protrudes inward from approximately the center of the inner peripheral front surface of the lower door frame base 12A1. The inner edge of the lower door boundary wall 12A2, facing the interior of the room, is provided with a seal material 12AT to ensure airtightness and watertightness between it and the lower frame 23A of the interior ventilation shoji screen 20A (described later). The lower door inner wall 12A3 protrudes from the interior corner of the lower door frame base 12A1 toward the interior, then bends toward the interior and again bends toward the interior. A resin-molded lower frame cover member 12C is attached to the outer surface of the lower door inner wall 12A3. The lower door support wall 12A4 is a thin plate that extends gradually downward from the exterior corner of the lower door frame base 12A1 toward the exterior. The exterior protrusion of the lower door support wall 12A4 is approximately the same as the exterior protrusion of the upper door support wall 11A2.

The metal frame portion 13A of the vertical door frame 13, which forms the hanging point, has a hanging point outer peripheral portion 13A1 and a hanging point inner peripheral portion 13A2, which are molded separately from each other. The hanging point outer peripheral portion 13A1 is hollow with a horizontally elongated, approximately rectangular cross section. A resin frame portion 13B is attached to this hanging point outer peripheral portion 13A1 so as to cover almost the entire visible surface facing the interior of the vehicle. The hanging point inner peripheral portion 13A2 is integrally molded with a vertical door recessed wall portion 13A2a, a vertical door inner recessed wall portion 13A2b, a vertical door outer recessed wall portion 13A2c, and a vertical door boundary wall portion 13A2d. The vertical door recessed wall portion 13A2a is a flat plate extending approximately vertically along the recessed direction. The vertical door inner sight wall 13A2b is a thin plate extending from the interior edge of the vertical door projection wall 13A2a toward the inner periphery. The vertical door outer sight wall 13A2c is a flat plate extending from the exterior edge of the vertical door projection wall 13A2a toward the inner periphery. The vertical door boundary wall 13A2d is a thin plate protruding toward the inner periphery at a portion of the projection surface on the inner periphery of the vertical door projection wall 13A2a that is approximately equidistant from the vertical door inner sight wall 13A2b and the vertical door outer sight wall 13A2c. A vertical frame inner periphery cover member 13C molded from resin is attached to the portion extending from the projection surface of the vertical door boundary wall 13A2d facing the interior of the vehicle to the projection surface on the inner periphery of the vertical door projection wall 13A2a. Additionally, a resin-molded vertical frame outer periphery cover member 13D is attached to the section extending from the interior-facing surface of the vertical door inner sight wall 13A2b to the outer surface of the vertical door recessed wall 13A2a. Furthermore, a seal material 13AT is provided on the inner periphery edge of the vertical frame inner periphery cover member 13C to ensure airtightness and watertightness between the vertical frame stile 24A of the interior ventilation shoji screen 20A (described below).

The metal frame portion 14A of the door vertical frame 14 on the door leading side has a door leading outer peripheral portion 14A1 and a door leading inner peripheral portion 14A2, which are molded separately from each other. The door leading outer peripheral portion 14A1 is hollow with a horizontally elongated, approximately rectangular cross section and differs from the hanging base outer peripheral portion 13A1 in that it has a smoke deflector portion 14A1a. Specifically, the door leading outer peripheral portion 14A1 is integrally formed with the smoke deflector portion 14A1a, which protrudes from the exterior corner of the outer periphery toward the outside and then bends toward the outer periphery. A resin frame portion 14B is attached to this door leading outer peripheral portion 14A1 so as to cover almost the entire visible surface facing the room. Like the inner hanging portion 13A2, the inner door edge portion 14A2 is integrally formed with a vertical door recess wall 14A2a, an inner vertical door recess wall 14A2b, an outer vertical door recess wall 14A2c, and a vertical door boundary wall 14A2d. It is also similar to the vertical door frame 13 on the hanging side in that it is equipped with a vertical frame inner periphery cover member 14C, a vertical frame outer periphery cover member 14D, and a weatherstripping material 14AT. Reference numeral 15 in the figure denotes a door handle attached to the vertical door frame 14 on the door edge side.

Two ventilation shoji screens 20A, 20B are arranged inside the door frame 10, movable up and down, on the interior side of boundary walls 12A2, 13A2d, and 14A2d, and on the exterior side of boundary walls 12A2, 13A2d, and 14A2d, respectively. The indoor ventilation shoji screen (hereinafter referred to as inner shoji screen 20A when distinguishing) is constructed by attaching an upper frame 22A, a lower frame 23A, and left and right vertical frames 24A around the four perimeter of rectangular double-glazed glass 21A. The outdoor ventilation shoji screen (hereinafter referred to as outer shoji screen 20B when distinguishing) is constructed by attaching an upper frame 22B, a lower frame 23B, and left and right vertical frames 24B around the four perimeter of rectangular double-glazed glass 21B. In this embodiment, the inner shoji screen 20A is positioned lower with the upper frame 22A of the inner shoji screen 20A and the lower frame 23B of the outer shoji screen 20B arranged side by side in the forward direction, and the dimensions of each ventilation shoji screen 20A, 20B along the top and bottom are set so that when the outer shoji screen 20B is positioned higher, it can block the opening in the door frame 10.

In addition, the inner shoji screen 20A has dimensions set along the left and right sides so that the visible surfaces of the left and right vertical frames 24A facing the room are simultaneously covered by the vertical door inner visible wall portions 13A2b and 14A2b, respectively, while a gap is secured between the vertical door visible wall portions 13A2a and 14A2a of the vertical door frames 13 and 14 and the visible surfaces of the vertical frames 24A, allowing them to be installed using the left and right Kendon method. In other words, the distance from the protruding edge (including the vertical frame outer periphery cover member 13D) of the vertical door inner sight wall 13A2b provided on one vertical door frame 13 to the vertical door sight wall 14A2a of the other vertical door frame 14, and the distance from the protruding edge (including the vertical frame outer periphery cover member 14D) of the vertical door inner sight wall 14A2b provided on the other vertical door frame 14 to the vertical door sight wall 13A2a of the one vertical door frame 13 are each set to be greater than the overall width dimension along the left and right of the inner shoji screen 20A. Therefore, for example, when one vertical stile 24A of the inner shoji screen 20A is moved so as to approach the vertical door frame 13, it is possible to position the other vertical stile 24A in a state where it is completely exposed to the outside from the vertical door inner sight wall 14A2b of the vertical door frame 14. Similarly, the outer shoji screen 20B has dimensions set along the left and right sides so that the visible surfaces of the left and right vertical frames 24B facing the outside of the room are simultaneously covered by the vertical door outer visible wall portions 13A2c and 14A2c, respectively, while a gap is secured between the vertical door visible wall portions 13A2a and 14A2a of the vertical door frames 13 and 14 and the visible surfaces of the vertical frames 24B, allowing them to be installed using the left and right Kendon method. In other words, the distance from the protruding edge of the vertical door outer sight wall 13A2c on one vertical door frame 13 to the vertical door sight wall 14A2a on the other vertical door frame 14, and the distance from the protruding edge of the vertical door outer sight wall 14A2c on the other vertical door frame 14 to the vertical door sight wall 13A2a on one vertical door frame 13, are each set larger than the overall width dimension along the left and right of the outer door screen 20B. Therefore, for example, when one vertical stile 24B of the outer door screen 20B is moved closer to the vertical door frame 13, the other vertical stile 24B can be positioned so that it is completely exposed to the outside from the vertical door outer sight wall 14A2c of the vertical door frame 14.

The upper frame 22A, lower frame 23A, and left and right vertical frames 24A of the inner shoji screen 20A, and the upper frame 22B and left and right vertical frames 24B of the outer shoji screen 20B are all composite structures comprising a metal frame portion 25M formed from a metal such as an aluminum alloy and a resin frame portion 25P formed from a resin, with the metal frame portion 25M facing the exterior, and holding the double-glazed glass 21A, 21B between them. The lower frame 23B of the outer shoji screen 20B has no portion facing the interior, so it is integrally formed from a metal such as an aluminum alloy. The frames that make up these ventilation shoji screens 20A, 20B are all extruded shapes, with both metal and resin portions formed, and each is configured to have a substantially uniform cross-sectional shape along its entire length. Note that the reference numeral 30 in the figure denotes a lattice screen door constructed by providing a net 32 and horizontal bars 33 inside the screen door frame 31, and is attached to the surface of the door panel 2 facing the outside so as to cover the opening in the door frame 10.

The ventilation shoji screens 20A, 20B each have a guide groove 26 on the outer peripheral surface of the left and right vertical stiles 24A, 24B facing the vertical door frames 13, 14, and the outer shoji screen 20B has a lower sliding piece 27 at the bottom end of each of the left and right vertical stiles 24B. The guide groove 26 is a recess in the metal frame portion 25M of the vertical stiles 24A, 24B, and is open at both the top and bottom ends, opening onto the outer peripheral surface of the vertical stiles 24A, 24B. As is clear from the figure, the guide groove 26 has guide pieces 26a protruding inward from the opening edge on both sides, and the width of the opening is configured to be smaller than the width of the interior. The lower sliding piece 27 is a block-shaped piece molded from resin, and protrudes outward toward the vertical door frames 13, 14 to fill the gap between the vertical door projection walls 13A2a, 14A2a of the vertical door frames 13, 14 and the projection surface of the vertical stile 24B, while also protruding downward from the underside of the lower stile 23B. As shown in FIG. 7 , the lower sliding piece 27 has an engagement groove 27b in the bottom wall 27a that protrudes beyond the projection surface of the vertical stile 24B. The engagement groove 27b penetrates the bottom wall 27a of the lower sliding piece 27 vertically and opens on the surface facing the vertical door frames 13, 14. Although not shown in the figure, upper sliding pieces are provided at the upper ends of the left and right vertical stiles 24A, 24B. Like the lower sliding piece 27, the upper sliding piece protrudes toward the vertical door frames 13, 14 to fill the gap between the vertical door projection walls 13A2a, 14A2a of the vertical door frames 13, 14 and the visible surfaces of the vertical stiles 24A, 24B. The lower sliding piece 27 is attached to the outer shoji screen 20B by screwing it from below into the underside of the lower stile 23B, and the upper sliding piece is attached to the ventilation shoji screen 20A, 20B by screwing it from above into the upper surfaces of the upper stiles 22A, 22B.

As shown in Figure 8, the inner and outer shoji screens 20A and 20B are connected to each other by a wire (cord) 40. A wire 40 is provided on each side, connecting the left-side vertical stile 24A of the inner shoji screen 20A to the left-side vertical stile 24B of the outer shoji screen 20B, and connecting the right-side vertical stile 24A of the inner shoji screen 20A to the right-side vertical stile 24B of the outer shoji screen 20B. The middle portions of each wire are wrapped around pulleys (reversing elements) 41 provided on the door frames 13 and 14, and both ends connecting to the vertical stiles 24A and 24B hang downward from the pulleys 41. The pulleys 41 are rotatably supported on a base 43 via a support shaft 42, and are attached to the inner peripheral surface of the door frames 13 and 14 via the base 43, with the support shaft 42 positioned approximately horizontally. The height position at which the pulley 41 is positioned is above the top surface of the lower sliding piece 27 when the outer screen 20B is moved to its highest position. The left-right position at which the pulley 41 is positioned is set so that one end of the wire 40 wound around the periphery and hanging down is aligned with the engagement groove 27b of the lower sliding piece 27.

The following describes in detail the connection structure of the wire 40 to the ventilation shoji screens 20A and 20B, along with an explanation of the features of the present invention. Note that the connection structure of the wire 40 to the ventilation shoji screens 20A and 20B is symmetrical on the left and right, so only one side will be explained below.

As shown in Figure 9, the wire 40 described above has an adjustment piece 44 attached to one end and an abutment member 45 attached to the other end. It is then wound around a pulley 41 before the ventilation screens 20A, 20B are erected. The adjustment piece 44 is integrally formed with an attachment piece 44a and a threaded piece 44b extending perpendicularly from one end of the attachment piece 44a, and one end of the wire 40 is attached to the attachment piece 44a. An adjustment screw 46 can be threaded onto the threaded piece 44b. The adjustment screw 46 has an outer diameter such that the shaft 46a can be inserted into the engagement groove 27b of the lower sliding piece 27, while the head 46b has a larger outer diameter than the engagement groove 27b. As shown in Figures 5, 8, and 10, the abutment member 45 is integrally formed with a substantially rectangular abutment base plate portion 45a and a connecting plate portion (protrusion) 45b extending perpendicularly from one side of the abutment base plate portion 45a. The other end of the wire 40 is connected via the extending edge of the connecting plate portion 45b. The abutment base plate portion 45a is plate-shaped and has dimensions that are larger than the opening width of the guide groove 26 when positioned along the front-to-back direction and can be accommodated within the guide groove 26. As is clear from the figures, guide ribs 45c are provided on both side edges of the abutment base plate portion 45a, bending at approximately right angles in opposite directions. By abutting these guide ribs 45c against the inside of the guide groove 26, the abutment member 45 can move only along the length of the vertical stile 24A, while movement in the front-to-back and front-to-back directions relative to the vertical stile 24A is prevented. The upper and lower surfaces of the contact base plate portion 45a extend approximately parallel to each other and are approximately horizontal when placed in the guide groove 26. The connecting plate portion 45b is flat and has a dimension that protrudes outward through the opening of the guide groove 26 when the contact base plate portion 45a is placed in the guide groove 26 of the vertical frame 24A, and the other end of the wire 40 is connected to its protruding edge. The protruding dimension of the connecting plate portion 45b is set so that when the wire 40 is wound around the pulley 41, the other end of the wire 40 extending downward from the pulley 41 is aligned approximately vertically.

Meanwhile, a stopper member 47 is pre-attached to the vertical frame 24A of the inner shoji screen 20A in the middle of the guide groove 26. As shown in Figures 5, 8, and 11, the stopper member 47 is integrally formed from a flat base plate 47a and abutment plate portions 47b bent in the same direction from both ends of the base plate 47a. The stopper member 47 is attached to the metal frame portion 25M of the vertical frame 24A via the base plate 47a, with the underside of the lower abutment plate portion 47b positioned in a pre-set position. The stopper member 47 is attached to the guide groove 26 of the vertical frame 24A by threading a screw 47c into the projected inner peripheral surface before the vertical frame 24A is attached to the double-glazed glass 21A. As is clear from the figure, when the stopper member 47 is attached to the vertical frame 24A, the abutment plate portion 47b protrudes from the base portion 47a toward the outer periphery, but the tip of the abutment plate portion 47b is sized so that it does not protrude outside the guide groove 26. Furthermore, the upper surface of the upper abutment plate portion 47b and the lower surface of the lower abutment plate portion 47b each extend approximately horizontally.

The positioning position of the stopper member 47 can be set as follows. That is, with the wire 40 wound around the pulley 41, the inner and outer shrouds 20A and 20B are positioned in the closed position as shown in Figure 8(a). From this position, the screw piece 44b of the adjustment piece 44 is brought into contact with the upper surface of the bottom wall 27a of the lower sliding piece 27, and the upper surface of the abutment member 45 provided on the wire 40 becomes the positioning position for the stopper member 47. Therefore, the stopper member 47 can be fixed to the vertical frame 24A with the lower abutment plate portion 47b abutting the upper surface of the abutment member 45.

To connect the wire 40 to the inner and outer shoji screens 20A and 20B, first, the inner and outer shoji screens 20A and 20B are installed inside the four-way assembled door frame 10. If the upper and lower sliding pieces 27 are left in their original state before installation, the ventilation shoji screens 20A and 20B can be easily installed into the door frame 10 using the left and right Kendon method, as shown in Figure 6.

Next, upper sliding pieces are attached to each of the installed ventilation shoji screens 20A, 20B, and lower sliding pieces 27 are attached to the outer shoji screen 20B. In this case, after installing the ventilation shoji screens 20A, 20B into the door frame 10, the visible and invisible surfaces of the vertical stiles 24A, 24B are covered by the vertical door frames 13, 14, as shown in Figure 3. However, the top surfaces of the upper stiles 22A, 22B and the bottom surfaces of the lower stiles 23A, 23B can be exposed to the outside by appropriately moving the ventilation shoji screens 20A, 20B relative to the door frame 10. Therefore, by moving the ventilation screens 20A, 20B up and down as needed to ensure space between the upper door frame 11 and the lower door frame 12 for placing tools as needed, it is possible to screw into the upper surfaces of the upper frames 22A, 22B and the lower surfaces of the lower frames 23A, 23B, and attach the upper and lower sliding pieces 27.

After the upper and lower sliding pieces 27 are attached, the gap between the vertical door frames 13, 14 and the vertical door projection walls 13A2a, 14A2a is reduced. This limits the left-right movement of the ventilation shoji screens 20A, 20B relative to the door frame 10. Therefore, even if the vertical stiles 24A, 24B of one of the ventilation shoji screens 20A, 20B are moved closer to one of the vertical door frames 13, 14, the other vertical stile 24A, 24B remains covered by the other vertical door frame 13, 14, eliminating the risk of the ventilation shoji screens 20A, 20B accidentally falling off the door frame 10.

From this state, as shown in Figures 12(a) and 12(b), the abutment member 45 is inserted from the lower end of the guide groove 26 into the vertical stile 24A of the inner shoji screen 20A and moved upward, until each upper end abuts against the lower abutment plate portion 47b of the stopper member 47, as shown in Figure 12(c). The adjustment screw 46 is then inserted into the guide groove 26 from the underside of the lower sliding piece 27, and with its head 46b abutting the underside, the adjustment screw 46 is screwed into the adjustment piece 44. When the adjustment screw 46 is screwed, the slack in the wire 40 is gradually removed, and once the wire 40 is taut, the inner shoji screen 20A and outer shoji screen 20B are connected to each other. In this state, for example, if the inner shoji screen 20A, which is located at the bottom, is moved upward, the outer shoji screen 20B will move downward in conjunction with it by the amount the wire 40 has moved upward. Conversely, if the inner shoji screen 20A is moved downward, the outer shoji screen 20B will move upward in conjunction with it by the amount the wire 40 has moved downward, improving the ease of opening and closing the ventilation shoji screens 20A, 20B. As mentioned above, the stopper member 47 is attached at a positioning position. Therefore, when the inner shoji screen 20A is positioned at the lowest position, the outer shoji screen 20B will be positioned at the highest position, and the opening of the door frame 10 will be closed.

As described above, the fittings described above make it possible to connect the wire 40 to the ventilation shoji screens 20A, 20B after they have been installed in the door frame 10. In other words, the door frame 10 and the ventilation shoji screens 20A, 20B can be individually assembled in advance. This eliminates the need for the tedious task of assembling the four sides of the ventilation shoji screens 20A, 20B, which are already connected by the wire 40, by arranging the upper door frame 11, lower door frame 12, and vertical door frames 13, 14 around each of them, simplifying the work of assembling the fittings. Furthermore, by adjusting the attachment position of the stopper member 47 on the vertical stile 24A of the inner shoji screen 20A, the connection position of the wire 40 can be freely changed relative to the visible surface of the vertical stile 24A. 13(a) to 13(c), for example, there is an advantage in that it is possible to apply a common wire 40 to fittings equipped with ventilation shoji screens 20AL, 20BL, 20A, 20B, 20AS, and 20BS of different overall heights. More specifically, even for inner shoji screens 20AL, 20A, and 20AS that have different height dimensions, by attaching stopper members 47 at positions equidistant from the upper frame 22A, it is possible to link them with outer shoji screens 20BL, 20B, and 20BS using wires 40 of a common length. As a result, these fittings can share parts used to connect the ventilation shoji screens 20AL, 20BL, the ventilation shoji screens 20A, 20B, and the ventilation shoji screens 20AS, 20BS, such as the wire 40, pulley 41, stopper member 47, and lower sliding piece 27, thereby reducing manufacturing costs.

While the above-described embodiment illustrates the door frame 10 and ventilation shoji screens 20A and 20B mounted on the door panel 2, the present invention can also be applied to frames and shoji screens mounted on the main body. Furthermore, the frames 11, 12, 13, and 14 that make up the door frame 10 and the stiles 22A, 22B, 23A, 23B, 24A, and 24B that make up the shoji screens 20A and 20B are illustrated as composites made of metal and resin. However, the present invention does not require the frames and stiles to be molded solely from metal or resin. Furthermore, while the present invention illustrates a fixture in which the inner shoji screen 20A is downward when closed, it is also possible to configure the fixture so that the inner shoji screen 20A is upward when closed. Furthermore, while a stopper member 47 is provided on the shoji screen that is downward when closed, the present invention is not limited to this. The same effect can be achieved by providing the stopper member 47 on the shoji screen that is upward when closed. Furthermore, while a wire 40 is used as the cord-like body and a pulley 41 is used as the reversing element, the present invention is not limited to these. For example, a chain could be used as the cord-like body and a sprocket as the reversing element. Alternatively, a non-rotating disk or semi-disk could be used as the reversing element, with a wire wound around its periphery.

In addition, while the above-described embodiment employs a configuration in which the contact surface between the stopper member 47 and the contact plate portion 47b extends substantially horizontally, it is also possible to configure the lower surface (inclined surface) 147a of the stopper member 147 and the upper surface (inclined surface) 145a of the contact member 145 to be inclined, as in the modified example shown in Figure 14. That is, in the modified example shown in Figure 14, the stopper member 147 has a lower surface 147a that gradually slopes downward toward the exterior, and the contact member 145 has an upper surface 145a that gradually slopes downward toward the exterior. In a fixture employing a stopper member 147 and a contact member 145 of this configuration, the lower surface 147a of the stopper member 147 and the upper surface 145a of the abutment member 145 abut against each other, thereby biasing the inner shoji screen 20A toward the exterior relative to the door frame 10. As a result, the weatherstripping material 12AT (13AT, 14AT) attached to the door frame 10 is pressed against the inner shoji screen 20A, improving the watertightness and airtightness between the inner shoji screen 20A and the door frame 10. In this modified example, the lower surface 147a of the stopper member 147 and the upper surface 145a of the abutment member 145 are inclined, but both do not necessarily need to be inclined; it is sufficient if at least one is inclined. In addition, in the modified example, the same components as those in the embodiment are designated by the same reference numerals.

As described above, the building fixture of the present invention comprises an inner and outer shoji screen on a frame body made up of left and right vertical frames and top and bottom horizontal frames assembled all around, and the inner and outer shoji screens are linked together by a rope-like body hanging down via an inversion element provided on the vertical frame, so that they move up and down in opposite directions.One of the inner and outer shoji screens has a guide groove along the vertical direction on the projected surface facing the vertical frame, and is provided with a stopper member, and one end of the rope-like body has an abutment member that is inserted into the guide groove from the lower end and abuts against the stopper member.
According to this invention, the abutment member inserted into the guide groove abuts against the stopper member, connecting the cord to the shoji screen. Therefore, if the stopper member is positioned above the bottom of the shoji screen, even if the abutment member is inserted from the bottom of the guide groove, the connecting position of the cord can be set above the bottom. This allows the inner and outer shoji screens to be connected to each other by the cord after they are installed in the frame, simplifying manufacturing. Furthermore, by adjusting the mounting position of the stopper member, a common cord can be used for building fixtures with shoji screens of different overall heights, which reduces manufacturing costs by sharing parts.

Furthermore, the present invention is characterized in that in the above-mentioned building fixtures, the other end of the cord-like body is connected to the lower end of the visible surface facing the vertical frame of either the inner shoji screen or the outer shoji screen.
According to this invention, the operation of connecting the other end of the cord-like body can be facilitated.

The present invention is also characterized in that, in the above-mentioned building fixture, the abutment member has a protruding portion that protrudes from the guide groove, and one end of the cord-like body is connected to the tip of the protruding portion.
According to this invention, the cord-like member is connected at a position spaced apart from the visible surface of the shoji screen, so that sufficient space can be secured for installing the reversing element.

Furthermore, the present invention is characterized in that, in the above-mentioned building fixture, at least one of the abutment member and the stopper member is provided with an inclined surface that urges either the inner shoji screen or the outer shoji screen toward the other when they abut against each other.
According to this invention, the inner and outer screens are biased in a direction that brings them closer to each other, thereby ensuring watertightness and airtightness between them.

Furthermore, the present invention is characterized in that, in the above-mentioned building fixtures, the left and right vertical frames each have a visible wall portion that faces the visible surface of the inner shoji screen and the visible surface of the outer shoji screen, and a visible wall portion that protrudes inward from the visible wall portion and covers the visible surface of the inner shoji screen and the visible surface of the outer shoji screen, and the distance from the protruding edge of the visible wall portion on one vertical frame to the visible wall portion of the other vertical frame is greater than the left and right width of the inner shoji screen and the outer shoji screen.
According to this invention, it is possible to set up the shoji screen before the abutment members are attached to the frame body using the left and right Kendon method, which makes it easier to set up the shoji screen.

In addition, the manufacturing method of the building materials of the present invention comprises an inner shoji screen and an outer shoji screen arranged so that they can move up and down on a frame body formed by assembling left and right vertical frames and upper and lower horizontal frames all around, a cord-like body connecting the inner shoji screen and the outer shoji screen, and an inversion element arranged on the vertical frames and inverting the cord-like body, and one of the inner shoji screens or the outer shoji screens has a guide groove along the vertical direction on the projected surface facing the vertical frames and a stopper member, and an abutment member provided on one end of the cord-like body abuts against the stopper member.This method of manufacturing building materials includes the steps of assembling the vertical frames and the horizontal frames all around to form the frame body, and then fitting the inner shoji screen and the outer shoji screen into the frame body, inserting the abutment member from the lower end of the guide groove and abutting it against the stopper member, and connecting the other end of the cord-like body to the other of the inner shoji screen or the outer shoji screen.
According to this invention, building fixtures can be constructed by fitting inner and outer shoji screens into a pre-constructed frame body, thereby facilitating manufacturing work.
