Description

[Technical Field]

[0001] The present invention relates to a fitting that restricts the movement of a shoji screen relative to a frame body by engaging a lock operating member provided on the frame body with an engaging member provided on the shoji screen. [Background technology]

[0002] In fittings such as double-hung windows and sliding windows, in which a shoji screen moves along the length of the frame material that makes up the frame, there are some that restrict the opening and closing movement of the shoji screen by operating a lock operation member provided on the frame. For example, in a double-hung window in which the shoji screen moves up and down along the length of the vertical frame relative to the frame, a lock operation member is provided on the vertical frame, and an engaging member is provided on the vertical stile of the shoji screen so as to protrude at a position corresponding to the lock operation member, and by engaging the lock operation member with the engaging member, it is possible to restrict the shoji screen from moving up and down relative to the frame (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 8-82138 Summary of the Invention [Problem to be solved by the invention]

[0004] However, the recessed surface of the vertical stile, which serves as a guide when moving the shoji screen relative to the frame, is always covered by the vertical frame. Therefore, it is not possible to screw a screw into the recessed surface of the vertical stile of the shoji screen installed in the frame, making it difficult to attach an engaging member. For this reason, attaching an engaging member to the recessed surface must be done before installing the shoji screen in the frame, which could lead to problems such as making the subsequent installation of the shoji screen in the frame more complicated. The above-mentioned problem can also occur in fittings in which the shoji screen moves left and right relative to the frame, between the recessed surface of the horizontal stile, which serves as a guide when moving the shoji screen relative to the frame, and the horizontal frame.

[0005] In view of the above-mentioned circumstances, the present invention aims to provide a fixture that allows an engaging member to be attached to a projecting surface that serves as a guide when moving a shoji screen, without complicating the work of fitting the shoji screen onto a frame body. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the building fixture of the present invention is a building fixture in which a shoji screen is arranged to be movable along the length of the guide frame material relative to a frame body formed by assembling a guide frame material and an end frame material around all four sides, and the movement of the shoji screen relative to the guide frame material is restricted by engaging a lock operating member provided on the guide frame material with an engaging member provided on the shoji screen, and is characterized in that an engaging portion is provided between the engaging member and the projected surface of the shoji screen facing the guide frame material, which engage with each other by moving along the extension direction of the projected surface and prevent the tip of the engaging member from moving in a direction away from the projected surface, and the engaging member is provided with a fixing portion which is fixed by screwing a screw member into the projected surface of the shoji screen facing the end frame material. [Effects of the Invention]

[0007] According to the present invention, the engaging member is inserted from the end of the shoji screen along the extension direction of the projected surface facing the guide frame material, thereby engaging the engaging portion, and then the fixing portion is fixed to the shoji screen by screwing the screw member into the projected surface of the shoji screen facing the end frame material, thereby preventing relative movement of the engaging member with respect to the shoji screen. This makes it possible to provide the engaging member on the projected surface of the shoji screen facing the guide frame material even after the shoji screen has been installed in the frame body. Therefore, there is no need to install the shoji screen with the engaging member attached, which prevents the work from becoming complicated. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

[0009] Preferred embodiments of the fittings according to the present invention will be described in detail below with reference to the accompanying drawings. Note that, for convenience, the terms "invisible direction" and "visible direction" will be used below. The "invisible direction" is the direction along the depth of the fittings, as indicated by arrow A in the drawings. A surface along the invisible direction will be referred to as a "visible face." The "visible direction" is the direction perpendicular to the invisible direction in the case of an object that extends horizontally, such as a sill. In the case of an object that extends vertically, such as a vertical frame, the "visible direction" is the horizontal direction perpendicular to the invisible direction. A surface along the invisible direction will be referred to as a "visible face."

[0010] 1 to 5 show a fitting according to an embodiment of the present invention. The fitting illustrated here is used as a back door and includes an opening frame 1 and a door panel 2. The opening frame 1 is configured 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 configured 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 interposing a hinge 3 between the door frame body 10 and one of the vertical opening frames 1C. The opening frame 1 is made up of an upper opening frame 1A, a lower opening frame 1B, and left and right vertical opening frames 1C. The opening frame 1 is a composite type 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, and are configured so that the portions along the entire longitudinal length thereof have a substantially uniform cross-sectional shape.

[0011] The door frame 10 is formed by framing all four sides of an upper door frame (end frame member) 11, a lower door frame (end frame member) 12, and left and right vertical door frames (guide frame members) 13, 14. The upper door frame 11, lower door frame 12, and vertical door frames 13, 14 are composite frames comprising a metal frame portion formed from a metal such as an aluminum alloy and a resin frame portion formed from a resin, and are supported by the opening frame 1 with the metal frame portion facing the exterior. The metal frame portion and the resin frame portion are extruded shapes, and each is configured so that the entire longitudinal length has a substantially uniform cross-sectional shape.

[0012] 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 the upper door frame base 11A1 so as to cover almost the entire surface facing the interior of the vehicle. A resin-molded upper frame recess member 11C 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-like member that extends approximately horizontally from the inner peripheral portion of the upper door frame base 11A1 on the surface facing the exterior of the vehicle, and then bends approximately at a right angle toward the inner peripheral surface.

[0013] The metal frame portion 12A of the lower door frame 12 is formed by integrally molding the lower door frame base 12A1, the lower door boundary wall portion 12A2, the lower door inner peripheral wall portion 12A3, and the 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 front surface of the lower door frame base 12A1, which is the inner peripheral side of the front surface. The lower door inner peripheral wall portion 12A3 protrudes inward from a corner on the interior side of the lower door frame base 12A1, then bends toward the interior, and bends again toward the interior. A resin-molded lower frame cover member 12C is attached to the outer surface of the lower door inner peripheral wall portion 12A3. The lower door support wall portion 12A4 is a thin plate-like member that extends gradually downward from an exterior corner on the inner peripheral side of the lower door frame base 12A1 toward the exterior. The protruding distance of the lower door support wall portion 12A4 toward the exterior is approximately the same as the protruding distance of the upper door support wall portion 11A2 toward the exterior.

[0014] The metal frame portion 13A of the vertical door frame 13, which is the hanging origin side, has a hanging origin outer peripheral portion 13A1 and a hanging origin inner peripheral portion 13A2, which are molded separately from each other. The hanging origin outer peripheral portion 13A1 is hollow with a horizontally elongated, approximately rectangular cross section. A resin frame portion 13B is attached to this hanging origin outer peripheral portion 13A1 so as to cover almost the entire visible surface facing the interior of the room. The hanging origin inner peripheral portion 13A2 is integrally molded with a vertical door recess wall portion 13A2a, a vertical door inner recess wall portion 13A2b, a vertical door outer recess wall portion 13A2c, and a vertical door boundary wall portion 13A2d. The vertical door recess wall portion 13A2a is a flat plate extending approximately vertically along the recess 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 room to the projection surface on the inner periphery of the vertical door projection wall 13A2a. In addition, a vertical frame outer periphery cover member 13D molded from resin is attached to the portion extending from the sight surface of the vertical door inner sight wall portion 13A2b facing the interior of the room to the sight surface on the outer periphery side of the vertical door sight wall portion 13A2a.

[0015] The metal frame 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. That is, 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 14B is attached to this door leading outer peripheral portion 14A1 so as to cover almost the entire visible surface facing the room. The door-end inner peripheral portion 14A2, like the hanging-end inner peripheral portion 13A2, is formed by integrally molding a vertical door recess wall portion 14A2a, a vertical door inner sight wall portion 14A2b, a vertical door outer sight wall portion 14A2c, and a vertical door boundary wall portion 14A2d. It is also similar to the hanging-end vertical door frame 13 in that it is provided with a vertical frame inner peripheral cover member 14C and a vertical frame outer peripheral cover member 14D. Reference numeral 15 in the figure denotes a door handle provided on the door-end vertical door frame 14. Reference numeral 16 denotes a door locking device that restricts the opening and closing of the door panel 2 relative to the opening frame 1.

[0016] The two ventilation shoji screens 20A, 20B are arranged inside the door frame 10 so as to be movable up and down along the longitudinal direction of the door frames 13, 14, respectively, at the inside portion of the room relative to the boundary walls 12A2, 13A2d, 14A2d and the outside portion of the room relative to the boundary walls 12A2, 13A2d, 14A2d. The indoor ventilation shoji screen (hereinafter referred to as the inner shoji screen (shoji screen) 20A when distinguished) is constructed by attaching an upper frame 22A, a lower frame 23A, and left and right vertical frames 24A to the four periphery of a rectangular double-glazed glass 21A. The outdoor ventilation shoji screen (hereinafter referred to as the outer shoji screen 20B when distinguished) is constructed by attaching an upper frame 22B, a lower frame 23B, and left and right vertical frames 24B to the four periphery of a rectangular double-glazed glass 21B. In this embodiment, the inner shoji screen 20A is positioned downward 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 are set so that when the outer shoji screen 20B is positioned upward, the opening in the door frame body 10 can be blocked.

[0017] Furthermore, the inner shoji screen 20A has dimensions set along the left and right so that the facing surfaces of the left and right stiles 24A facing the room are simultaneously covered by the vertical door inner facing wall 13A2b and the vertical door inner facing wall 14A2b, respectively, while ensuring a gap that allows left and right hand movements between the vertical door facing walls 13A2a, 14A2a of the vertical door frames 13, 14 and the facing surfaces of the stiles 24A. In other words, for example, when one stile 24A of the inner shoji screen 20A is moved closer to the vertical door frame 13, the other stile 24A can be positioned in a state where it is completely exposed to the outside from the vertical door inner facing wall 14A2b of the vertical door frame 14. Similarly, the outer shoji screen 20B has dimensions set along the left and right so that the visible surfaces of the left and right vertical frames 24B facing the outside are simultaneously covered by the vertical door outer visible wall 13A2c and the vertical door outer visible wall 14A2c, respectively, while ensuring a gap that allows left and right hand movements between the vertical door visible wall 13A2a, 14A2a of the vertical door frames 13, 14 and the visible surfaces of the vertical frames 24B. Therefore, for example, when one vertical frame 24B of the outer shoji screen 20B is moved closer to the vertical door frame 13, the other vertical frame 24B can be positioned in a state where it is completely exposed to the outside from the vertical door outer visible wall 14A2c of the vertical door frame 14.

[0018] 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 with a metal frame portion 25M made of a metal such as an aluminum alloy and a resin frame portion 25P made of a resin, with the metal frame portion 25M facing the outside of the room 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 of the room and is therefore integrally formed of a metal such as an aluminum alloy. The frames that make up these ventilation shoji screens 20A, 20B are all extruded shapes, whether made of metal or resin, and are configured so that each has a substantially uniform cross-sectional shape along its entire length. In addition, the symbol 30 in the figure indicates a lattice screen door constructed by providing a net 32 ​​and horizontal bars 33 inside a screen door frame 31, and is attached to the surface of the door panel 2 facing outside so as to cover the opening of the door frame 10.

[0019] Each ventilation shoji screen 20A, 20B has a guide groove 26 on the outer peripheral surface of each of the left and right vertical stiles 24A, 24B facing the vertical door frames 13, 14, and sliding pieces 27, 28 are provided at the upper and lower ends of each of the left and right vertical stiles 24A, 24B. The guide groove 26 is a recess provided in the metal frame portion 25M of each vertical stile 24A, 24B, and is open at both upper and lower end faces and opens onto the outer peripheral surface of each vertical stile 24A, 24B. As is clear from the figure, each 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 sliding pieces 27, 28 are block-shaped pieces molded from resin and are provided so as to protrude outward toward the vertical door frames 13, 14 so as to fill the gap between the vertical door recessed wall portions 13A2a, 14A2a of the vertical door frames 13, 14 and the facing surfaces of the vertical stiles 24A, 24B. The sliding piece 27 provided at the top of the inner shoji screen 20A is attached by screwing a screw member 27a from above onto the upper surface of the upper stile 22A (see Figure 9). The sliding piece 28 provided at the outer shoji screen 20B is also attached by screwing a screw member (not shown) from above the upper stile 22B or below the lower stile 23B. Although not shown in the figures, these ventilation shoji screens 20A, 20B are connected to each other by a wire. The wire is wound around pulleys (not shown) attached to the door vertical frames 13 and 14, and connects the ventilation shoji screens 20A and 20B to each other so that, for example, when the inner shoji screen 20A is moved upward, the outer shoji screen 20B moves downward.

[0020] Furthermore, this fitting is provided with a shoji locking device 40 between one vertical stile 24A of the inner shoji 20A, which is at the bottom when closed, and the corresponding vertical door frame 13. The shoji locking device 40 is configured with a lock operating member 41 provided on the vertical door frame 13 and an engaging member 42 provided on the vertical stile 24A. In this embodiment, the shoji locking device 40 is provided between the vertical door frame 13, which is the hanging side, and the vertical stile 24A of the inner shoji 20A.

[0021] The lock operation member 41 is fixed to the door vertical frame 13 via a mounting base 41a on 13A2b and protrudes into the room via the vertical frame outer periphery cover member 13D. The lock operation member 41 is constantly biased so that the fitting portion 41b at its tip protrudes toward the outside of the room by the spring force of a return spring (not shown) interposed between the lock operation member 41 and the mounting base 41a. By grasping the portion of the lock operation member 41 that protrudes into the room and pulling it against the spring force of the return spring, the fitting portion 41b can be moved toward the inside of the room. When the operating force on the lock operation member 41 is removed from this state, the spring force of the return spring causes the fitting portion 41b to return to its original position.

[0022] As shown in Figures 5 and 6, the engagement member 42 is integrally formed with an engagement base plate portion 42a, a fixing plate portion 42b, an insertion piece (engagement portion) 42c, and an engagement plate portion 42d, and is attached via an attachment plate 43 to the outer peripheral surface of the metal frame portion 25M that constitutes the vertical frame 24A. The engagement base plate portion 42a is a flat, rectangular, thin plate. Positioning notches 42e are provided on both side edges of the upper portion of the engagement base plate portion 42a. The positioning notches 42e are rectangular and open to the side edges at the same positions. The fixing plate portion 42b is a flat, thin plate extending approximately perpendicularly from the upper end of the engagement base plate portion 42a. Screw insertion holes 42f are formed along the top and bottom of this fixing plate portion 42b. The screw insertion holes 42f are provided at positions corresponding to the screw holes 22Aa for attaching the sliding piece 27 to the upper end of the vertical stile 24A and the upper surface of the upper stile 22A. The insertion piece 42c protrudes downward from the lower edge of the engagement base plate 42a and is a flat plate with a width smaller than that of the engagement base plate 42a. The engagement plate 42d is a thin plate extending from one side edge of the engagement base plate 42a in a direction substantially perpendicular to the fixing plate 42b, its vertical dimension being shorter than that of the engagement base plate 42a, and it is provided below the lower edge of the positioning notch 42e. The engagement plate 42d is provided with a guide inclined portion 42g and an engagement hole 42h. The guide inclined portions 42g are thin plates projecting from the upper and lower portions of the extended edge of the engagement plate portion 42d, and are gradually inclined toward the exterior as they move away from the engagement plate portion 42d. The engagement holes 42h are square through-holes sized to allow the fitting portion 41b of the lock operation member 41 to pass through. For example, three are formed at the top and bottom along the extended edge of the engagement plate portion 42d. The number of engagement holes 42h is not necessarily limited to three. The engagement plate portion 42d provided with these guide inclined portions 42g and engagement holes 42h is configured to be located closer to the interior than the fitting portion 41b of the lock operation member 41 when the engagement member 42 is attached to the projected surface of the outer periphery of the vertical stile 24A via the engagement base plate portion 42a and the mounting plate 43 (described later) with the inner sash 20A installed in the door frame 10. The guide inclined portion 42g and the engagement hole 42h are provided at positions on the engagement plate portion 42d that allow them to face the fitting portion 41b of the lock operation member 41.The engagement hole 42h at the top is located at a position where the fitting portion 41b of the lock operation member 41 passes through when the inner screen 20A is placed in the closed position. Note that the symbol 42i in the figure is a screw insertion notch formed at a position corresponding to the screw hole 43b of the mounting base portion 43a described later.

[0023] As shown in FIG. 7, the mounting plate 43 is integrally formed with a mounting base portion 43a, positioning protrusions 43c, and a bottom plate portion 43d. The mounting base portion 43a is a flat, vertically elongated rectangular thin plate slightly larger in vertical dimension than the engaging plate portion 42d of the engaging member 42, and wider than the engaging plate portion 42d. Screw holes 43b are provided in the middle and lower portions of the mounting base portion 43a. The positioning protrusions 43c protrude forward from both sides of the upper edge of the mounting base portion 43a. A gap is provided between the positioning protrusions 43c that is slightly larger than the width of the portion of the engaging base portion 42a where the positioning notch 42e is formed, but smaller than the width of the engaging base portion 42a. The bottom plate portion 43d is bent from the lower end of the mounting base portion 43a in the same direction as the positioning protrusions 43c. The bottom plate portion 43d is formed with an insertion hole (engagement portion) 43e of a size that allows the insertion piece 42c of the engagement member 42 to be inserted but prevents the insertion of the engagement base plate portion 42a. A dimension is set between the bottom plate portion 43d and the positioning protrusion 43c so that the portion of the engagement base plate portion 42a from the positioning notch 42e to the lower end can be positioned in a state where the insertion piece 42c is inserted into the insertion hole 43e.

[0024] The following describes in detail the structure for attaching the engaging member 42 to the inner sash 20A, along with a description of the features of the present invention. First, as shown in Figure 8, when attaching the engaging member 42 to the inner sash 20A, a mounting plate 43 is attached in advance to the outer peripheral surface of the vertical stile 24A facing the vertical door frame 13 before the inner stile 20A is installed in the door frame 10. The mounting plate 43 can be attached to the vertical stile 24A by abutting the mounting base portion 43a against the outer peripheral surface of the metal stile portion 25M of the vertical stile 24A before the upper stile 22A, lower stile 23A, and vertical stile 24A of the inner sash 20A are assembled all around, and then threading the screw member 44 from the inner peripheral side of the metal stile portion 25M into the screw hole 43b of the mounting base portion 43a through the screw insertion hole 25Ma and then. The screw insertion hole 25Ma of the metal frame portion 25M is set so that the distance from the top surface of the upper frame 22A to the positioning protrusion 43c matches the dimension from the fixing plate portion 42b of the engaging member 42 to the positioning notch 42e.

[0025] After the mounting plate 43 is attached to the vertical frame 24A, the upper frame 22A, the lower frame 23A, and the vertical frame 24A are attached to the four sides of the double-glazed glass 21A and connected together to form the inner shoji screen 20A. Even when the upper frame 22A, the lower frame 23A, and the vertical frame 24A are assembled all around, as long as they are in the state before the sliding piece 27 is attached, the inner shoji screen 20A can be easily installed into the door frame 10 using the left and right push-ons, as shown in Figure 4.

[0026] Here, when the inner screen 20A is installed in the door frame 10, the visible surfaces of the outer peripheries of the left and right vertical stiles 24A are covered by the vertical door frames 13 and 14, respectively. However, the upper surface, which is the visible surface of the upper stile 22A, and the lower surface, which is the visible surface of the lower stile 23A, can be exposed by moving the inner screen 20A up and down appropriately relative to the door frame 10. Therefore, as shown in Figure 8, the engagement member 42 can be inserted from above the inner screen 20A into the gap between the vertical frame inner peripheral cover member 13C of the vertical door frame 13 and the vertical stile 24A, and the insertion piece 42c can be moved along the extension direction of the vertical stile 24A to insert it into the insertion hole 43e of the mounting plate 43. At this time, if the inner screen 20A is moved toward the opposite vertical door frame 14 inside the door frame body 10, the gap between the vertical frame inner periphery cover member 13C and the vertical stile 24A can be enlarged, making the above-mentioned work easier. Also, as shown in Figure 9(a), if the engaging member 42 is tilted so that the upper end is separated from the vertical stile 24A, the positioning protrusion 43c and the engaging base plate portion 42a will not come into contact with each other, and the insertion piece 42c can be easily inserted into the insertion hole 43e.

[0027] After the insertion piece 42c is inserted into the insertion hole 43e, as shown in Figure 9(b), by bringing the upper end of the engagement plate portion 42d close to the vertical frame 24A, the positioning protrusion 43c is inserted into the positioning notch 42e and the fixing plate portion 42b comes into contact with the upper surface of the upper frame 22A. Therefore, as shown in Figures 9 and 10, by screwing the screw member 27a into the screw hole 22Aa of the upper frame 22A through the screw insertion hole 42f of the sliding piece 27 and the fixing plate portion 42b, the engagement member 42 can be fixed to the inner shoji screen 20A with the engagement plate portion 42d protruding from the guide groove 26 of the vertical frame 24A together with the sliding piece 27. In this state, the positioning protrusion 43c is inserted into the positioning notch 42e, preventing relative movement of the engaging member 42 relative to the stile 24A along the projection direction, and the insertion piece 42c is inserted into the insertion hole 43e, preventing relative movement of the engaging member 42 relative to the stile 24A along the projection direction and movement away from the projection surface of the stile 24A. Furthermore, when the positioning protrusion 43c is inserted into the positioning notch 42e, the mounting position of the engaging member 42 relative to the stile 24A is accurately determined. As a result, for example, if the engaging portion 41b of the lock operation member 41 is inserted into the engaging hole 42h with the inner stile 20A closed relative to the door frame 10, upward movement of the inner stile 20A is prevented via the engaging member 42. As described above, the inner stile 20A and the outer stile 20B are connected to each other by a wire. Therefore, when the inner shoji 20A is prevented from moving upward relative to the door frame 10, the outer shoji 20B cannot be moved downward, and the ventilation shoji 20A, 20B can be locked relative to the door frame 10.

[0028] Incidentally, by moving the inner shoji 20A slightly upward and inserting the engaging portion 41b into the middle engaging hole 42h or the lower engaging hole 42h, it is possible to prevent the inner shoji 20A and the outer shoji 20B from moving up and down when they are partway open. Furthermore, when the inner shoji 20A is moved downward from a state in which the inner shoji 20A and the outer shoji 20B are fully open, the engaging portion 41b abuts against the guide inclined portion 42g provided on the engaging member 42, and the inclining action of the guide inclined portion 42g causes the engaging portion 41b to move toward the interior of the room against the spring force of the return spring. After that, when the inner shoji 20A moves until the position of the engaging hole 42h matches the engaging portion 41b, the spring force of the return spring causes the engaging portion 41b to penetrate the engaging hole 42h. Therefore, if the inner shroud 20A is closed without operating the lock operating member 41, it is possible to prevent the inner shroud 20A from moving thereafter.

[0029] The sliding piece 28 can be attached to the inner and outer shoji screens 20A and 20B at an appropriate timing, for example, after the engaging member 42 is attached to the inner shoji screen 20A. In this case, as with the sliding piece 27, the sliding piece 28 can be easily attached to the outer shoji screen 20B installed in the door frame 10 by screwing a screw member from above the upper stile 22B or below the lower stile 23B. After the sliding pieces 27 and 28 are attached, the gap between the sliding pieces 27 and 28 and the vertical door projection walls 13A2a and 14A2a of the vertical door frames 13 and 14 is reduced. This limits the left-right movement of the ventilation shoji screens 20A and 20B relative to the door frame 10. Therefore, even when one of the vertical frames 24A, 24B of the ventilation shoji screens 20A, 20B is moved closer to one of the vertical door frames 13, 14, the other vertical frame 24A, 24B remains covered by the other vertical door frame 13, 14, and there is no risk of the ventilation shoji screens 20A, 20B accidentally falling off from the door frame body 10.

[0030] In this way, with the above-described fixture, the engaging member 42 is inserted from the end of the inner shoji 20A along the extension direction of the vertical stile 24A, so that the insertion piece 42c is inserted into the insertion hole 43e, and then the screw member 27a is screwed into the upper surface of the inner shoji 20A to fix the fixing plate portion 42b to the inner shoji 20A, preventing relative movement of the engaging member 42 with respect to the inner shoji 20A. This makes it possible to attach the engaging member 42 to the vertical stile 24A of the inner shoji 20A even after the inner shoji 20A has been installed into the door frame 10. Therefore, there is no need to install the inner shoji 20A with the engaging member 42 attached, which prevents the work from becoming complicated.

[0031] While the above-described embodiment illustrates the door frame 10 and the ventilation shoji screens 20A, 20B attached to the door panel 2, the present invention can also be applied to frames and shoji screens attached to a building frame. While the frame constituting the door frame 10 and the stiles constituting the shoji screens 20A, 20B are illustrated as composites made of metal and resin, 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 fitting in which the shoji screens 20A, 20B move up and down relative to the door frame 10, the present invention can also be applied to fittings in which the shoji screens move left and right. In this case, a locking operation member may be provided on the upper or lower frame, and an engaging member may be provided on the upper or lower stile. Furthermore, while the present invention illustrates a fitting in which two shoji screens are attached to the frame, one shoji screen is sufficient.

[0032] In the above-described embodiment, the engaging member 42 is attached to the vertical stile 24A via the mounting plate 43, eliminating the need for special processing such as providing an engaging portion on the vertical stile 24A. However, the present invention is not limited to this, and for example, an engaging portion for attaching the engaging member directly to the vertical stile may be provided. Note that the engaging member 42 is attached using the screw member 27a for attaching the sliding piece 27, which reduces the number of parts, but the present invention is not limited to this.

[0033] Furthermore, in the above-described embodiment, the insertion piece 42c provided on the engaging member 42 is inserted into the insertion hole 43e on the shoji screen side, but it is also possible to form an insertion hole in the engaging member and provide an insertion piece on the shoji screen side. Also, while the fixing plate portion 42b of the engaging member 42 is fixed to the upper frame 22A of the shoji screen 20A, it may also be fixed to the lower frame 23A. Note that, although a plate-shaped fixing plate portion 42b is exemplified as the fixing portion, the fixing portion does not necessarily have to be plate-shaped.

[0034] As described above, the building fixture of the present invention is a building fixture in which a shoji screen is arranged to be movable along the length of the guide frame material relative to a frame body formed by assembling a guide frame material and an end frame material around all four sides, and the movement of the shoji screen relative to the guide frame material is restricted by engaging a lock operating member provided on the guide frame material with an engaging member provided on the shoji screen, and is characterized in that an engaging portion is provided between the engaging member and the projected surface of the shoji screen facing the guide frame material, which engage with each other by moving along the extension direction of the projected surface and prevent the tip of the engaging member from moving in a direction away from the projected surface, and the engaging member is provided with a fixing portion which is fixed by screwing a screw member into the projected surface of the shoji screen facing the end frame material.
