Description

This disclosure relates to building materials.

Conventionally, a fitting has been known that comprises a frame body, a mullion that extends vertically midway along the left-right direction of the frame body, and a panel that is placed inside the frame body on one side of the mullion in the left-right direction (see, for example, Patent Document 1).

Japanese Patent Application Laid-Open No. 2008-285921

When attaching paneling to the inside of a frame and mullions, it can be difficult to create clearance between the paneling and the frame or between the paneling and the mullions when the frame's vertical members or the mullions are narrow, making it difficult to attach the paneling. Therefore, there is a demand for a system that makes it easy to attach paneling to the mullions within the frame.

The purpose of this disclosure is to provide a fixture that allows for easy attachment of paneling to mullions within the frame.

This disclosure relates to a fitting comprising a frame body, a upright positioned midway within the frame body in the horizontal direction and extending vertically, and a panel positioned in one of the openings separated by the upright within the frame body, the upright being configured to be movable horizontally by a guide portion provided on the frame body or the upright, and being fixed to the frame body at a predetermined horizontal position.

The upper frame body 211 has an upper frame exterior groove 211a formed on the exterior side X1 and open downward, and an upper frame interior groove 211b formed on the interior side X2 and open downward.

The upper frame outer groove 211a is where the upper end of the outer shoji screen 5 is placed on the outer side X1 of the upper frame 21. The upper frame outer groove 211a guides the left-right movement of the upper end of the outer shoji screen 5.

The upper frame interior groove 211b has a fixed glass placement groove 211d (see Figure 4) formed on the left-right side of the fixed unit 4, and a screen placement groove 211c (see Figure 3) formed on the left-right side of the outer screen 5. As shown in Figure 3, a screen attachment 211e is placed in the screen placement groove 211c. The screen placement groove 211c guides the left-right movement of the upper end of the pleated screen 6 via the screen attachment 211e. As shown in Figure 4, the upper end of the glass panel 41 of the fixed unit 4 is placed in the fixed glass placement groove 211d.

As shown in Figures 3 and 4, the lower frame 22 has a lower frame main body 221, a lower frame interior surface cover 222 arranged on the surface of the interior side X2, and a lower frame interior upper end cover 223 attached to the upper end of the lower frame interior surface cover 222.

The lower frame interior surface cover 222 has a fixed-side lower frame interior surface cover 222b (see Figure 4) formed on the left-right side of the fixed section 4, and a shoji-side lower frame interior surface cover 222a (see Figure 3) formed on the left-right side of the outer shoji screen 5, with a gap between it and the fixed-side lower frame interior surface cover 222b.

The lower frame interior upper end cover 223 comprises a fixed-side lower frame interior upper end cover 223b (see Figure 4) formed on the left-right side of the fixed section 4, and a shoji-side lower frame interior upper end cover 223a (see Figure 3) formed on the left-right side of the outer shoji screen 5, with a gap between it and the fixed-side lower frame interior upper end cover 223b.

The lower frame body 221 has a lower frame rail 221a formed on the exterior side X1 and protruding upward, and a lower frame interior groove 221b formed on the interior side X2 and opening upward.

The lower end of the outer shoji screen 5 is positioned on the lower frame rail 221a on the outside side X1 of the lower frame 22. The lower frame rail 221a guides the left-right movement of the lower end of the outer shoji screen 5.

The lower frame interior groove 221b has a fixed glass placement groove 221d (see Figure 4) formed on the left-right side of the fixed unit 4, and a screen placement groove 221c (see Figure 3) formed on the left-right side of the outer screen 5. As shown in Figure 3, a screen attachment 221e is placed in the screen placement groove 221c. The screen placement groove 221c guides the left-right movement of the lower end of the pleated screen 6 via the screen attachment 221e. As shown in Figure 4, the lower end of the glass panel 41 of the fixed unit 4 is placed in the fixed glass placement groove 221d.

As shown in Figure 5, the vertical frames 23, 24 comprise vertical frame bodies 231, 241, vertical frame interior surface covers 232, 242 arranged on the surface of the interior side X2, and vertical frame interior end covers 233, 243 attached to the inner lateral ends of the vertical frame interior surface covers 232, 242.

As shown in Figure 1, the mullion 3 is positioned extending vertically at a midpoint in the left-right direction on the indoor side X2 of the frame body 2. The opening of the frame body 2 is divided into left and right halves by the mullion 3 midway in the left-right direction. The mullion 3 separates the left and right sides of the opening of the frame body 2. As a result, on the indoor side X2 of the frame body 2, a fixed portion 4 is formed on one left-right side of the frame body 2, and an opening 25 that is opened and closed by an outer screen 5 is formed on the other left-right side of the frame body 2. Details of the mounting structure of the mullion 3 will be described later.

As shown in Figures 1 and 2, the fixed section 4 is constructed by fixing a glass panel 41 (face material) as a surface material to the mullion 3 and the frame 2 on the left-right side of the fixed section 4 of the mullion 3 within the frame 2. The fixed section 4 is a fixed window that cannot be opened or closed. The fixed section 4 is constructed by fitting the glass panel 41 as a surface material to the inner periphery of the area surrounded by the mullion 3, upper frame 21, lower frame 22, and vertical frame 24 of the frame 2 on the indoor side X2 on one side of the left-right direction of the mullion 3, which is located midway between the left and right sides of the frame 2.

As shown in Figures 4 and 5, the outer edge of the glass panel 41 is positioned in the fixed glass placement grooves 31, 211d, 221d, and 241d of the upright 3 (vertical member), upper frame 21 (upper member), lower frame 22 (lower member), and vertical frame 24 (vertical member). The outer edge of the glass panel 41 on the left-right side of the upright 3 is pressed against the upright 3 by a bucking edge 35 (bucking edge member), and the outer edges of the upper, lower, and left-right sides opposite the upright 3 are pressed against fixed-side attachments 214, 224, and 244 fixed to the interior side X2 of the upper frame 21, lower frame 22, and vertical frame 24, respectively, by bucking edges 215, 225, and 245. The bucking edges 35, 215, 225, and 245 are attached and fixed by being hooked onto and engaged with the upright 3, upper frame 21, lower frame 22, and vertical frame 24, respectively.

As shown in Figure 6, the pressing edge 35 that presses the outer edge of the glass panel 41 against the mullion 3 presses the airtight material 35a toward the glass panel 41. The airtight material 35a is positioned in contact with the exterior X1 surface (one side surface) of the end of the glass panel 41 that is placed in the FIX glass placement groove 31 (surface material placement groove) of the mullion 3 (surface material holding member). In this embodiment, the airtight material 35a is, for example, a dry gasket.

The ridge 35 presses the airtight material 35a toward the glass panel 41 on the exterior side X1 of the edge of the glass panel 41.

As shown in Figure 6, the ridge 35 is crank-shaped and extends vertically as shown in Figure 7. As shown in Figure 6, the ridge 35 is fixed to the inner plate portion 361 of the exterior portion 36 of the mullion 3 with screws 37 (adjustable fasteners).

The pressing edge 35 has an exterior facing fixing plate 351, a facing extending plate 352 extending from one of the left-right ends of the exterior facing fixing plate 351 toward the interior side X2, an interior facing extending plate 353 extending from one of the left-right ends of the exterior facing fixing plate 351 on the interior side X2, and an airtight material pressing protrusion 354 protruding from the surface of the interior facing extending plate 353 toward the interior side X2 and pressing the airtight material 35a against the glass panel 41.

The fixing plate 351 of the ridge 35 extending in the direction of view toward the outside of the room is fixed to the inner plate portion 361 of the outside part 36 of the mullion 3 by screws 37. As shown in Figure 7, multiple screws 37 are provided along the longitudinal direction of the ridge 35 to fix the ridge 35 in place.

The screws 37 are configured to adjust the pressure of the flange 35 against the glass panel 41, and secure the flange 35 to the mullion 3 with the pressure of the flange 35 against the glass panel 41 adjusted. By adjusting the pressure of the flange 35 against the glass panel 41 depending on how tightly the screws 37 are tightened, the pressure with which the airtight material 35a is pressed against the glass panel 41 can be adjusted and secured.

As shown in Figure 7, the screw 37 is inserted from the outside X1 through the hole 362a in the outer plate 362 of the outside part 36 of the upright 3, and as shown in Figure 8, it penetrates and secures the inner plate 361 of the outside part 36 of the upright 3 and the ledge 35 in the forward direction.

By providing a structure in which the flange 35 is fixed with the screw 37 as described above, the flange 35 can be fixed in a state pressed against the glass panel 41 by the screw 37, preventing the mullion 3 from coming loose from the glass panel 41 even if the front dimension (width in the left-right direction) of the mullion 3 is narrow. Furthermore, because the flange 35 can be pressed against the glass panel 41 by the screw 37, the flange 35 can be pressed more firmly against the glass panel 41 than with a structure in which the glass panel is placed in the glass placement groove and then an airtight material is inserted and attached. This further prevents the mullion 3 from coming loose from the glass panel 41.

As shown in Figure 5, the outer shoji screen 5 is a shoji screen that can be opened and closed by sliding left and right (horizontally) within the frame body 2 on the outside side X1 of the frame body 2. The outer shoji screen 5 is configured to be able to open and close an opening 25 formed on the left and right side of the outer shoji screen 5 relative to the mullion 3 located midway between the left and right sides of the frame body 2. When viewed from the inside-outside direction, the outer shoji screen 5 is in a closed position when it overlaps the opening 25, and is in an open position when it is moved left and right to the outside side X1 of the FIX unit 4.

As shown in Figures 3 and 5, the outer shoji screen 5 is constructed by fitting a glass panel 55 onto the inner periphery of a rectangular frame body 50 made up of an upper frame 51, a lower frame 52, a vertical frame 53 located at the door tip, and a vertical frame 54 located at the door tail. The upper end of the outer shoji screen 5 is positioned in the upper frame outer groove 211a of the upper frame 21 so that it can move left and right, and the lower end engages with the lower frame rail 221a of the lower frame 22 so that it can move left and right.

As shown in Figures 1 and 2, a handle 531 is attached to the vertical frame 53 located on the door edge side. The handle 531 is attached to the visible surface on the inner circumferential side of the vertical frame 53 in the left-right direction, on the room side X2, closer to the interior than the face material 55 of the outer shoji screen 5.

The mounting structure of the mullion 3 will now be described in detail. As shown in Figures 9 and 10, the mullion 3 is configured to be movable left and right (horizontally) by an upper guide portion 61 (guide portion) and a lower guide portion 62 (guide portion) provided on the mullion 3, and is fixed to the frame body 2 at a predetermined position in the left and right direction (horizontally).

As shown in Figure 9, the upper guide portion 61 is fixed to the upper end of the upright 3. The upper guide portion 61 is formed from an L-shaped metal fitting. The upper guide portion 61 has a vertical extension portion 611 that is fixed to the upper end of the upright 3 and extends in the vertical direction, and a horizontal extension portion 612 that extends from the upper end of the vertical extension portion 611 to one side in the left-right direction.

The vertical extension portion 611 is formed as a plate with a thickness in the left-right direction (front view). The vertical extension portion 611 has a width in the front view (indoor-outdoor direction) and extends vertically. The vertical extension portion 611 is connected and fixed to the upper end of the mullion 3, along the front face of the mullion 3, at the upper end of the mullion 3.

The horizontally extending portion 612 is formed as a plate with a thickness in the vertical direction (view direction). The horizontally extending portion 612 has a width in the view direction (indoor/outdoor direction) and extends in the left-right direction. The horizontally extending portion 612 extends from the upper end of the vertically extending portion 611 toward the opening 25 in the left-right direction.

The horizontal extension 612 is positioned movably in the left-right direction in the upper frame room inner groove 211b of the upper frame 21, on the left-right opening 25 side of the upright 3.

The horizontally extending portion 612 has a guide groove 613 shaped like an elongated hole that penetrates vertically and extends horizontally. The horizontally extending portion 612 is temporarily fixed by a screw 612a inserted into the guide groove 613 and is configured to be movable horizontally along the guide groove 613. The horizontal position of the upright 3 is adjusted when the screw 612a is inserted into the guide groove 613 and the horizontally extending portion 612 and the upper frame 21 are temporarily fixed by the screw 612a. Then, when the horizontal position of the horizontally extending portion 612 has been adjusted to a predetermined position, the horizontally extending portion 612 and the upper frame 21 are permanently fixed by the screw 612a, and the horizontally extending portion 612 and the upper frame 21 are fixed by additional fixing screws 612b and 612c.

As shown in Figure 10, the lower guide portion 62 is fixed to the lower end of the upright 3. The lower guide portion 62 is formed from an L-shaped metal fitting. The lower guide portion 62 has a vertical extension portion 621 that is fixed to the lower end of the upright 3 and extends in the vertical direction, and a horizontal extension portion 622 that extends from the lower end of the vertical extension portion 621 to one side in the left-right direction.

The vertical extension portion 621 is formed as a plate with a thickness in the left-right direction (front view). The vertical extension portion 621 has a width in the front view (indoor-outdoor direction) and extends vertically. The vertical extension portion 621 is connected and fixed to the lower end of the mullion 3 in a state that aligns with the front face of the mullion 3 at the lower end of the mullion 3.

The laterally extending portion 622 is formed as a plate with a thickness in the vertical direction (view direction). The laterally extending portion 622 has a width in the view direction (indoor/outdoor direction) and extends in the left-right direction. The laterally extending portion 622 extends from the lower end of the vertical extending portion 621 toward the opening 25 in the left-right direction.

The horizontal extension 622 is positioned movably in the left-right direction in the lower frame interior groove 221b of the lower frame 22, on the left-right opening 25 side of the upright 3.

The horizontally extending portion 622 has a guide groove 623 shaped like an elongated hole that penetrates vertically and extends horizontally. The horizontally extending portion 622 is temporarily fixed by a screw 622a inserted into the guide groove 623 and is movable horizontally along the guide groove 623. The horizontal position of the upright 3 can be adjusted when the screw 622a is inserted into the guide groove 623 and the horizontally extending portion 622 and the lower frame 22 are temporarily fixed by the screw 622a. Once the horizontal position of the horizontally extending portion 622 has been adjusted to a predetermined position, the horizontally extending portion 622 and the lower frame 22 are permanently fixed by the screw 622a, and the horizontally extending portion 622 and the lower frame 22 are then fixed by additional fixing screws 622b and 622c.

Next, we will explain the procedure for inserting the glass panel 41 into the FIX unit 4 and fixing the upright 3 to the upper frame 21 and lower frame 22. First, as shown in the top diagram of Figure 11A, the upright 3 is temporarily fixed with screws 612a and 622a, and then, as shown in the middle diagram of Figure 11A, it is retracted from the glass panel 41. Then, as shown in the bottom diagram of Figure 11A, the end of the glass panel 41 on the vertical frame 24 side of the FIX unit 4 is placed in contact with the FIX-side attachment 244 fixed to the vertical frame 24.

Next, as shown in the upper diagram of Figure 11B, the mullion 3 is moved toward the glass panel 41 to position the mullion 3 in the left-right direction.

Then, with the upright 3 positioned at a predetermined position in the left-right direction, as shown in the bottom diagram of Figure 11B, screws 612a and 622a are permanently fixed, and additional fixing screws 612b, 612c, 622b, and 622c are used to fix the guide parts (upper guide part 61, lower guide part 62) and the frame body 2 (upper frame 21, lower frame 22).

Next, as shown in the lower diagram of Figure 11B, the outside X1 surface of the end of the glass panel 41 on the vertical frame 24 side is pressed with the edge 245, and the outer shoji screen 5 is inserted into the outside X1 of the opening 25 of the frame body 2. In this way, the fixed portion 4 is formed in the fitting 1, and the outer shoji screen 5 can be positioned on the opening 25 of the frame body 2.

By configuring the mullions 3 to be movable left and right as described above, the glass panels 41 can be installed with gaps left and right, making installation of the glass panels 41 easier.

The above-mentioned mullions 3 are configured to be movable left and right, and are fixed to the upper frame 21 and lower frame 22 at predetermined left and right positions. Therefore, it is necessary to ensure the watertightness of the upper and lower ends of the mullions 3, taking into account that the mullions 3 are configured to be movable left and right. Therefore, in this embodiment, the upper and lower ends of the mullions 3 are provided with watertight structures such as those shown in Figures 12 to 19 to ensure watertightness between them and the frame body 2.

The watertight structure of the upright 3 and the frame 2 (upper frame 21, lower frame 22) will be explained. As shown in Figure 12, the upper end of the upright 3 is located midway between the upper frame 21 in the left-right direction, and as shown in Figure 16, the lower end is located midway between the lower frame 22 in the left-right direction.

In detail, as shown in Figure 12, the upper end of the mullion 3 is positioned in close contact with the watertight components located in the gap between the fixed-side upper frame interior surface cover 212b and the shoji-side upper frame interior surface cover 212a, and the watertight components located in the gap between the fixed-side upper frame interior lower end cover 213b and the shoji-side upper frame interior lower end cover 213a. As shown in Figure 16, the lower end of the mullion 3 is positioned in close contact with the watertight components located in the gap between the fixed-side lower frame interior surface cover 222b and the shoji-side lower frame interior surface cover 222a, and the watertight components located in the gap between the fixed-side lower frame interior upper end cover 223b and the shoji-side lower frame interior upper end cover 223a.

As shown in Figures 12 to 15, a mullion-side upper watertight member 32 (upper watertight member) is attached to the upper end of the mullion 3. An upper frame-side upper watertight member 71 (upper watertight member) is placed where the upper end of the mullion 3 is placed on the upper frame 21. The mullion-side upper watertight member 32 is formed in a block shape and is placed in the upper frame room side groove 211b of the upper frame 21.

As shown in Figures 12 to 15, the upper frame-side watertight member 71 is positioned on the vertical frame 24 side in the left-right direction relative to the upper end of the upright 3. The upper frame-side watertight member 71 has a watertight block 711 formed in a block shape extending in the projection direction. A watertight sealant 711a is provided on the top surface of the watertight block 711. A watertight sealant 711b is provided on the surface of the watertight block 711 facing the upright 3. A watertight sealant 711c is provided on the surface of the watertight block 711 facing the vertical frame 24, on the indoor side X2 side.

The upper frame side watertight member 71 is installed with the watertight sealant 711a abutting the underside of the upper frame 21, the watertight sealant 711b abutting the upright 3 and abutting the longitudinal end faces 212c, 213c of the shoji side upper frame interior surface cover 212a and the shoji side upper frame interior lower end cover 213a of the upper frame 21, and the watertight sealant 711c abutting the longitudinal end faces 212d, 213d of the fixed side upper frame interior surface cover 212b and the fixed side upper frame interior lower end cover 213b of the upper frame 21. This improves the watertight and airtight performance between the upper end of the upright 3 and the upper frame 21.

As shown in Figures 16 to 19, a lower mullion-side watertight member 33 (lower watertight member) is attached to the lower end of the mullion 3. A lower frame-side watertight member 72 (lower watertight member) is placed where the lower end of the mullion 3 is placed on the lower frame 22. The lower mullion-side watertight member 33 is formed in a block shape and is placed in the lower frame room side groove 221b of the lower frame 22.

As shown in Figures 16 to 19, the lower frame-side watertight member 72 is positioned on the vertical frame 24 side in the left-right direction relative to the lower end of the upright 3. The lower frame-side watertight member 72 has a watertight block 721 formed in a block shape extending in the projection direction. A watertight sealant 721a is provided on the underside of the watertight block 721. A watertight sealant 721b is provided on the surface of the watertight block 721 facing the upright 3. A watertight sealant 721c is provided on the surface of the watertight block 721 facing the vertical frame 24, on the indoor side X2 side.

The lower frame watertight member 72 is installed with the watertight sealant 721a abutting the upper surface of the lower frame 22, the watertight sealant 721b abutting the upright 3 and abutting the longitudinal end faces 222c, 223c of the shoji-side lower frame interior surface cover 222a and the shoji-side lower frame interior upper end cover 223a of the lower frame 22, and the watertight sealant 721c abutting the longitudinal end faces 222d, 223d of the fixed-side lower frame interior surface cover 222b and the fixed-side lower frame interior upper end cover 223b of the lower frame 22. This improves the watertight and airtight performance between the upper end of the upright 3 and the lower frame 22.

Next, we will explain the structure designed from a security perspective. As shown in Figure 5, the fitting 1 of this embodiment is a so-called externally movable fitting, in which the outer shoji screen 5 is arranged so that it can move left and right on the outside side X1 of the fixed part 4. When the outer shoji screen 5 is in the closed position, the vertical frame 54 arranged on the door end side of the outer shoji screen 5 is positioned on the outside side X1 of the mullion 3, and is arranged overlapping the mullion 3 when viewed from the inside-outside direction.

The pressing edges 35, 215, 225, and 245 that press against the outer edge of the glass panel 41 on all four sides of the fixed section 4, as shown in Figures 4 and 5, press the outer edge on the left-right side of the mullion 3 against the interior side X2 of the fixed glass placement groove 31 of the mullion 3 by the pressing edges 35, and also press against the fixed side attachments 214, 224, and 244 fixed to the interior side X2 of the upper frame 21, lower frame 22, and vertical frame 24, respectively, by the pressing edges 215, 225, and 245.

As shown in Figure 20, in the FIX section 4, the battens 35, 215, 225, and 245 are attached to the upper frame 21, lower frame 22, mullion 3, and vertical frame 24. The battens 35, 215, 225, and 245 are composed of an upper batten 215, a lower batten 225, a vertical batten 35 on the vertical frame side (vertical batten on one side), and a vertical batten 245 on the vertical frame side (vertical batten on the other side) that press against one side of the edge of the glass panel 41.

The upper battens 215, lower battens 225, upright-side vertical battens 35, and vertical frame-side vertical battens 245 are arranged along the four sides formed by the upper frame 21, lower frame 22, upright 3, and vertical frame 24. In this embodiment, the upper battens 215, lower battens 225, upright-side vertical battens 35, and vertical frame-side vertical battens 245 form four-sided battens that press against the glass panel 41 on the four sides formed by the upper frame 21, lower frame 22, upright 3, and vertical frame 24.

On one side (upper frame 3 side) of the four battens (upper batten 215, lower batten 225, upright side vertical batten 35, and vertical frame side vertical batten 245), the longitudinal end of the upper batten 215 is positioned above the longitudinal upper end of the upright side vertical batten 35, and the longitudinal end of the lower batten 225 is positioned below the longitudinal lower end of the upright side vertical batten 35, resulting in a so-called horizontally dominated structure.

On the other left-right side (vertical frame 24 side) of the four battens (upper batten 215, lower batten 225, upright side vertical batten 35, and vertical frame side vertical batten 245), the longitudinal end of the upper batten 215 is positioned on the inner left-right side of the upper longitudinal end of the vertical frame side vertical batten 245, and the longitudinal end of the lower batten 225 is positioned on the inner left-right side of the lower longitudinal end of the vertical frame side vertical batten 245, resulting in a so-called vertically dominated structure.

Here, the battens (upper battens 215, lower battens 225, upright-side vertical battens 35, and vertical-frame-side vertical battens 245) are attached to the inner periphery of the upright 3, upper frame 21, lower frame 22, and vertical frame 24. Therefore, when removing the battens (upper battens 215, lower battens 225, upright-side vertical battens 35, and vertical-frame-side vertical battens 245) attached to the inner periphery of the upright 3, upper frame 21, lower frame 22, and vertical frame 24, it is necessary to remove them by moving further inward from the inner periphery of the upright 3, upper frame 21, lower frame 22, and vertical frame 24.

In this embodiment, when removing the upper batten 215, lower batten 225, upright side vertical batten 35 (vertical batten on one side), and vertical frame side vertical batten 245 (vertical batten on the other side), first remove the upright side vertical batten 35 from the upright 3. Then, remove the upper batten 215 from the upper frame 21 and the lower batten 225 from the lower frame 22, and then remove the vertical frame side vertical batten 245 from the vertical frame 24, thereby removing the upper batten 215, lower batten 225, upright side vertical batten 35 (vertical batten on one side), and vertical frame side vertical batten 245 (vertical batten on the other side).

In this embodiment, when the upright-side vertical battens 35 are not removed from the upright 3, even if an attempt is made to move the upper battens 215 and lower battens 225 toward the inner periphery of the upright 3, upper frame 21, lower frame 22, and vertical frame 24, the upright-side vertical battens 35 gets in the way, making it impossible to remove the upper battens 215 and lower battens 225. Furthermore, even if an attempt is made to move the vertical-frame-side vertical battens 245 toward the inner periphery of the upright 3, upper frame 21, lower frame 22, and vertical frame 24, the upper battens 215 and lower battens 225 get in the way, making it impossible to remove the vertical-frame-side vertical battens 245. Therefore, when removing the upper battens 215, lower battens 225, upright-side vertical battens 35, and vertical-frame-side vertical battens 245, it is necessary to first remove the upright-side vertical battens 35 from the upright 3.

Here, as shown in Figures 5 and 20, the vertical frame 54 of the outer shoji screen 5 is positioned on the outside side X1 of the upright side vertical frame 35 when the outer shoji screen 5 is in the closed position. Therefore, on one side (the upright side) of the four frame flaps (upper flaps 215, lower flaps 225, upright side vertical frame flaps 35, and vertical frame side vertical frame flaps 245) in the left-right direction, when the outer shoji screen 5 is in the closed position, the upright side vertical frame flaps 35 are positioned in a state where they are covered by the vertical frame 54 of the outer shoji screen 5.

As a result, when the outer shoji screen 5 is in the closed position, the vertical frame 54 of the outer shoji screen 5 covers the vertical ledge 35 on the outside side X1, and the vertical ledge 35 on the outside side X1 cannot be removed from the mullion 3.

Therefore, by locking the outer screen 5 while it is in the closed position, the upright side vertical batten 35 cannot be removed from the outside X1, and therefore the upper batten 215, lower batten 225, and vertical frame side vertical batten 245 cannot be removed either. As a result, the four-sided batten (upper batten 215, lower batten 225, upright side vertical batten 35, and vertical frame side vertical batten 245) cannot be removed, and the glass panel 41 cannot be removed. This improves security.

Conventionally, when a fitting 1 is configured as an externally movable type, in which the outer shoji screen 5 is positioned so that it can move left and right on the outside side X1 of the fixed section, and both left and right ends of the four-sided battens are configured with a vertical offset structure, it is possible to move the upper battens 215 and the lower battens 225 inward in the vertical direction from the outside X1. Furthermore, if both left and right ends of the four-sided battens are configured with a horizontal offset structure, it is possible to move one vertical batten and the other vertical batten inward in the horizontal direction from the outside X1. For this reason, conventionally, when the battens are configured so that they can be removed from the outside X1, glass fasteners have been provided on the glass panels for security reasons.

In contrast, in this disclosure, the four-sided battens (upper battens 215, lower battens 225, upright-side vertical battens 35, and vertical frame-side vertical battens 245) are configured with a so-called horizontal lead structure on one side (the upright 3 side) of the four-sided battens (upper battens 215, lower battens 225, upright-side vertical battens 35, and vertical frame-side vertical battens 245) in the left-right direction, and are configured with a so-called vertical lead structure on the other side (the vertical frame 24 side) of the four-sided battens (upper battens 215, lower battens 225, upright-side vertical battens 35, and vertical frame-side vertical battens 245). Therefore, the vertical battens (upright-side vertical battens 35) that are configured with a so-called horizontal lead structure must first be removed before the other battens can be removed. Furthermore, when the outer screen 5 is closed and locked, the vertical frame stile 54 of the outer screen 5 covers the upright-side vertical battens 35 on the outside side X1, preventing the upright-side vertical battens 35 from being removed, thereby improving security performance.

The first embodiment provides the following advantages. The fitting 1 of this embodiment comprises a frame body 2, a mullion 3 that is positioned midway laterally within the frame body 2 and extends vertically, and a glass panel 41 that is positioned in one of the openings separated by the mullion 3 within the frame body 2. The mullion 3 is configured to be movable left and right by an upper guide portion 61 and a lower guide portion 62 provided on the mullion 3, and is fixed to the frame body 2 at a predetermined position in the left and right direction. This allows the glass panel 41 to be erected by moving the mullion 3 left and right, facilitating the installation of the glass panel 41.

In addition, in this embodiment, the upper guide portion 61 and the lower guide portion 62 are formed in an L-shape and have vertically extending portions 611, 621 connected to the upright 3, and horizontally extending portions 612, 622 extending horizontally from the ends of the vertically extending portions 611, 621. The horizontally extending portions 612, 622 have horizontally extending guide grooves 613, 623 and are configured to be movable left and right along the guide grooves 613, 623, and are fixed to the frame body 2 at predetermined left and right positions. This allows for a simple configuration in which the upright 3 can be moved left and right to attach the glass panel 41 to the frame body 2.

In addition, in this embodiment, the upper part of the mullion 3 is provided with a watertight upper part of the upright side 32 attached to the mullion 3 and an upper frame side upper watertight part 71 attached to the upper frame 21, and the lower part of the mullion 3 is provided with a watertight lower part of the upright side 33 attached to the mullion 3 and a lower frame side lower watertight part 72 attached to the lower frame 22. This ensures watertight and airtight performance between the frame body 2 and the mullion 3, which can move left and right.

Next, the second embodiment will be described. The explanation for the first embodiment can be applied to points not explained in the second embodiment. In the second embodiment, the same components as those in the first embodiment are designated by the same reference numerals as those in the first embodiment, and their explanation will be omitted.

In contrast to the four-sided flaps of the FIX section 4 in the first embodiment, the second embodiment has a three-sided flaps as shown in Figure 21. In the second embodiment, the vertical frame 24 and vertical frame-side vertical flaps 245 shown in Figure 20 in the first embodiment are not provided. The upper flaps 215, lower flaps 225, and upright-side vertical flaps 35 in the second embodiment form three-sided flaps that press against the glass panel 41 on the three sides defined by the upper frame 21, lower frame 22, and upright 3.

On one side (upper side) of the three-sided flaps (upper flaps 215, lower flaps 225, and upright side vertical flaps 35), the longitudinal end of the upper flaps 215 is positioned above the longitudinal upper end of the upright side vertical flaps 35, and the longitudinal end of the lower flaps 225 is positioned below the longitudinal lower end of the upright side vertical flaps 35, resulting in a so-called horizontally dominated structure.

On the other left-right side of the three-sided flaps (upper flaps 215, lower flaps 225, and upright-side vertical flaps 35), no vertical flaps are provided at the other left-right ends of the upper flaps 215 and lower flaps 225, leaving the ends open.

In the second embodiment, in which the upper batten 215, lower batten 225, and upholstery-side vertical batten 35 form a three-sided batten, just as in the first embodiment, the vertical batten (upholstery-side vertical batten 35) that forms the so-called horizontally dominant structure must first be removed before the other battens can be removed. Also, just as in the first embodiment, when the outer screen 5 is closed and locked, the vertical frame 54 of the outer screen 5 covers the upholstery-side vertical batten 35 on the outside side X1, preventing the upholstery-side vertical batten 35 from being removed, thereby improving security.

The above describes one preferred embodiment of the present disclosure, but the present disclosure is not limited to the above-described embodiment and can be modified as appropriate.
