The embodiments of this disclosure will be described in detail below with reference to the drawings. The first embodiment of the joinery 1 will be described. In this specification, "face direction" refers to the direction of the surface material of the joinery 1 fitted into an opening formed in the wall of a building, and "depth direction" refers to the thickness direction (i.e., depth direction) of the surface material. The "depth direction" is also the interior-exterior direction. "Face surface" refers to the exterior and interior faces of the joinery 1, respectively, and "depth surface" refers to the surface of the joinery 1 extending in the interior-exterior direction. In the drawings, the exterior side of the joinery 1 is referred to as the exterior side X1, and the interior side of the joinery 1 is referred to as the interior side X2. Furthermore, the "horizontal direction" of the exterior sash 5 is also referred to as the left-right direction.

As shown in Figures 1 and 2, the joinery 1 comprises a frame 2 attached to an opening in a building structure (not shown), a mullion 3 (a panel holding member) positioned within the frame 2, a fixed section 4 positioned on the interior side X2 of the frame 2 on one side of the mullion 3 in the left-right direction, an exterior sash 5 positioned to be movable in the left-right direction on the exterior side X1 of the frame 2, and a pleated screen door 6 (a retractable screen door) positioned on the interior side X2 of the frame 2 on the other side of the mullion 3 in the left-right direction.

The frame 2 is constructed by framing the upper frame 21, the lower frame 22, and a pair of left and right vertical frames 23 and 24 in a rectangular shape.

As shown in Figures 3 and 4, the upper frame 21 comprises an upper frame body 211, an upper frame indoor surface cover 212 positioned on the indoor side X2 surface, and an upper frame indoor lower end cover 213 attached to the lower end of the upper frame indoor surface cover 212.

The upper frame interior surface cover 212 comprises a fixed-side upper frame interior surface cover 212b (see Figure 4) formed on the left-right fixed section 4 side, and a sash-side upper frame interior surface cover 212a (see Figure 3) formed on the left-right outer sash 5 side and positioned with a gap between it and the fixed-side upper frame interior surface cover 212b.

The upper frame body 211 has an upper frame outdoor groove 211a formed on the outdoor side X1 and opening downwards, and an upper frame indoor groove 211b formed on the indoor side X2 and opening downwards.

The upper end of the outer sash 5 is positioned in the upper frame exterior groove 211a on the exterior side X1 of the upper frame 21. The upper frame exterior groove 211a guides the lateral movement of the upper end of the outer sash 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 section 4, and a screen door placement groove 211c (see Figure 3) formed on the left-right side of the outer sash 5. As shown in Figure 3, a screen door attachment 211e is placed in the screen door placement groove 211c. The screen door placement groove 211c guides the left-right movement of the upper end of the pleated screen door 6 via the screen door attachment 211e. As shown in Figure 4, the upper end of the glass panel 41 of the fixed section 4 is placed in the fixed glass placement groove 211d.

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

The lower frame interior surface cover 222 comprises a fixed-side lower frame interior surface cover 222b (see Figure 4) formed on the left-right fixed section 4 side, and a sash-side lower frame interior surface cover 222a (see Figure 3) formed on the left-right outer sash 5 side and positioned 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 fixed section 4 side, and a sash-side lower frame interior upper end cover 223a (see Figure 3) formed on the left-right outer sash 5 side, positioned 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 outdoor side X1 and projecting upward, and a lower frame indoor groove 221b formed on the indoor side X2 and opening upward.

The lower end of the outer sash 5 is positioned on the lower frame rail 221a on the outdoor side X1 of the lower frame 22. The lower frame rail 221a guides the lateral movement of the lower end of the outer sash 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 section 4, and a screen door placement groove 221c (see Figure 3) formed on the left-right side of the outer sash 5. As shown in Figure 3, a screen door attachment 221e is positioned in the screen door placement groove 221c. The screen door placement groove 221c guides the left-right movement of the lower end of the pleated screen door 6 via the screen door attachment 221e. As shown in Figure 4, the lower end of the glass panel 41 of the fixed section 4 is positioned in the fixed glass placement groove 221d.

As shown in Figure 5, the vertical frames 23 and 24 each comprise a vertical frame body 231 and 241, vertical frame indoor surface covers 232 and 242 positioned on the indoor side surface X2, and vertical frame indoor end covers 233 and 243 attached to the inner circumference ends of the vertical frame indoor surface covers 232 and 242 in the left-right direction.

As shown in Figure 1, the mullion 3 is positioned extending vertically at an intermediate point in the left-right direction on the indoor side X2 of the frame 2. The opening of the frame 2 is divided left and right by the mullion 3. The mullion 3 partitions the left and right sides of the opening of the frame 2. As a result, on the indoor side X2 of the frame 2, a fixed section 4 is formed on one side in the left-right direction of the frame 2, and an opening 25, which is opened and closed by the outer sash 5, is formed on the other side in the left-right direction of the frame 2. Details of the mounting structure of the mullion 3 will be described later.

As shown in Figures 1 and 2, the FIX section 4 is constructed by fixing a glass panel 41 (facing material) as a facing material to the mullion 3 and the frame 2 on the left-right side of the FIX section 4 within the frame 2. The FIX section 4 is a fixed window that cannot be opened or closed. The FIX section 4 is constructed by fitting the glass panel 41 as a facing material into the inner circumference of the portion enclosed by the mullion 3, upper frame 21, lower frame 22, and vertical frame 24 of the frame 2, on the indoor side X2 in the left-right direction relative to the mullion 3 located midway in the left-right direction 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 mullion 3 (vertical member), upper frame 21 (upper member), lower frame 22 (lower member), and vertical frame 24 (vertical member), respectively. The outer edge of the glass panel 41 on the side of the mullion 3 in the left-right direction is pressed against the mullion 3 by a glazing strip 35 (glazing strip member), while the upper, lower, and left-right outer edges opposite to the mullion 3 are pressed against fixed side attachments 214, 224, and 244 fixed to the indoor side X2 of the upper frame 21, lower frame 22, and vertical frame 24, respectively, by glazing strips 215, 225, and 245. The glazing strips 35, 215, 225, and 245 are attached and fixed in a state where they are hooked and engaged with the mullion 3, upper frame 21, lower frame 22, and vertical frame 24, respectively.

As shown in Figure 6, the retaining strip 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 outdoor-facing X1 surface (one side surface) of the end of the glass panel 41, which is placed in the fixed glass placement groove 31 (panel placement groove) of the mullion 3 (panel material holding member). In this embodiment, the airtight material 35a is, for example, a dry gasket.

The trim strip 35 presses the airtight material 35a toward the glass panel 41 on the exterior side X1 of the end of the glass panel 41.

As shown in Figure 6, the trim strip 35 is formed in a crank shape and extends vertically as shown in Figure 7. As shown in Figure 6, the trim strip 35 is fixed to the inner plate portion 361 of the outdoor portion 36 of the mullion 3 by screws 37 (adjustable fasteners).

The trim strip 35 comprises an exterior-facing fixing plate 351, a depth-extending plate 352 extending from one end of the exterior-facing fixing plate 351 in the left-right direction toward the interior X2, an interior-facing fixing plate 353 extending from the interior X2 end of the exterior-facing fixing plate 351 toward one side in the left-right direction, and an airtight material pressing projection 354 that protrudes from the surface of the interior-facing fixing plate 353 toward the interior X2 and presses the airtight material 35a against the glass panel 41.

The fixing plate 351 extending in the outdoor-facing direction of the trim 35 is fixed to the inner plate portion 361 of the outdoor-facing portion 36 of the mullion 3 by screws 37. As shown in Figure 7, multiple screws 37 are provided along the longitudinal direction of the trim 35 to secure the trim 35.

The screw 37 is configured to allow adjustment of the pressing force of the trim 35 toward the glass panel 41. The trim 35 is fixed to the mullion 3 with the pressing force of the trim 35 toward the glass panel 41 adjusted. By adjusting the tightness of the screw 37, the pressing force of the trim 35 toward the glass panel 41 can be adjusted, thereby fixing the airtight seal 35a to the glass panel 41.

As shown in Figure 7, the screw 37 is inserted from the outdoor side X1 through the hole 362a in the outer plate portion 362 of the outdoor side portion 36 of the mullion 3, and as shown in Figure 8, it penetrates the inner plate portion 361 of the outdoor side portion 36 of the mullion 3 and the trim 35 in the depth direction to secure them.

As described above, by providing a structure in which the retaining strip 35 is fixed with screws 37, the retaining strip 35 can be fixed in a state where it is pressed against the glass panel 41 by the screws 37. Therefore, even if the dimensions of the mullion 3 in the visible direction (width in the left-right direction) are narrow, it is possible to prevent the mullion 3 from coming out of the glass panel 41. Furthermore, because the retaining strip 35 can be pressed against the glass panel 41 by the screws 37, the retaining strip 35 can be pressed more firmly against the glass panel 41 than in a structure in which the airtight material is inserted and installed after the glass panel is placed in the glass placement groove. Therefore, it is possible to further prevent the mullion 3 from coming out of the glass panel 41.

As shown in Figure 5, the outer sash 5 is a sash that can be opened and closed by sliding horizontally (left-right) within the frame 2 on the outdoor side X1. The outer sash 5 is configured to open and close an opening 25 formed on the outer sash 5 side in the left-right direction relative to the mullion 3, which is located midway between the left and right sides of the frame 2. When viewed from the indoor/outdoor direction, the outer sash 5 is in the closed position when it overlaps the opening 25, and moves horizontally to the outdoor side X1 of the FIX section 4, thereby moving to the open position.

As shown in Figures 3 and 5, the outer sash 5 is constructed by assembling an upper frame 51, a lower frame 52, a vertical frame 53 positioned on the leading edge side, and a vertical frame 54 positioned on the trailing edge side into a rectangular frame body 50, and then housing a glass panel 55 on the inner circumference of this frame. The upper end of the outer sash 5 is positioned to be movable in the left-right direction within the upper frame exterior groove 211a of the upper frame 21, and the lower end is engaged with the lower frame rail 221a of the lower frame 22 to be movable in the left-right direction.

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 inner circumference of the vertical frame 53 in the left-right direction, on the interior side X2 of the outer shoji screen 5's facing material 55.

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

As shown in Figure 9, the upper guide portion 61 is fixed to the upper end of the mullion 3. The upper guide portion 61 is formed from an L-shaped metal fitting. The upper guide portion 61 has a vertically extending portion 611 fixed to the upper end of the mullion 3 and extending vertically, and a horizontally extending portion 612 extending away from the upper end of the vertically extending portion 611 in one direction.

The vertically extending portion 611 is formed in a plate-like shape with thickness in the left-right direction (visible direction). The vertically extending portion 611 has width in the depth direction (indoor/outdoor direction) and extends vertically. The vertically extending portion 611 is connected and fixed to the upper end of the mullion 3, along the depth surface of the mullion 3.

The lateral extension portion 612 is formed in a plate-like shape with thickness in the vertical direction (visible direction). The lateral extension portion 612 has width in the depth direction (indoor/outdoor direction) and extends in the left-right direction. The lateral extension portion 612 extends from the upper end of the vertical extension portion 611 toward the opening 25 in the left-right direction.

The lateral extension portion 612 is positioned on the left-right opening 25 side of the mullion 3, and is movably positioned in the upper frame interior groove 211b of the upper frame 21 so as to be movable in the left-right direction.

The lateral extension portion 612 has an elongated guide groove 613 that penetrates vertically and extends horizontally. The lateral extension portion 612 is configured to be movable horizontally along the guide groove 613 while temporarily fixed by a screw 612a inserted into the guide groove 613. With the lateral extension portion 612 and the upper frame 21 temporarily fixed by the screw 612a, the horizontal position of the mullion 3 is adjusted. Then, with the horizontal position of the lateral extension portion 612 adjusted to a predetermined position, the lateral extension portion 612 and the upper frame 21 are permanently fixed by the screw 612a, and the lateral extension portion 612 and the upper frame 21 are further 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 mullion 3. The lower guide portion 62 is formed from an L-shaped metal fitting. The lower guide portion 62 has a vertically extending portion 621 fixed to the lower end of the mullion 3 and extending vertically, and a horizontally extending portion 622 extending away from the lower end of the vertically extending portion 621 in one direction.

The vertically extending portion 621 is formed in a plate-like shape with thickness in the left-right direction (visible direction). The vertically extending portion 621 has width in the depth direction (indoor/outdoor direction) and extends vertically. At the lower end of the mullion 3, the vertically extending portion 621 is connected and fixed to the lower end of the mullion 3, along the depth surface of the mullion 3.

The lateral extension portion 622 is formed in a plate-like shape with thickness in the vertical direction (visible direction). The lateral extension portion 622 has width in the depth direction (indoor/outdoor direction) and extends in the left-right direction. The lateral extension portion 622 extends from the lower end of the vertical extension portion 621 toward the opening 25 in the left-right direction.

The lateral extension portion 622 is positioned on the left-right opening 25 side of the mullion 3, and is movably positioned in the lower frame indoor groove 221b of the lower frame 22.

The lateral extension portion 622 has an elongated guide groove 623 that penetrates vertically and extends horizontally. The lateral extension portion 622 is configured to be movable horizontally along the guide groove 623 while temporarily fixed by a screw 622a inserted into the guide groove 623. With the lateral extension portion 622 and the lower frame 22 temporarily fixed by the screw 622a, the horizontal position of the mullion 3 is adjusted. Once the horizontal position of the lateral extension portion 622 is adjusted to a predetermined position, the lateral extension portion 622 and the lower frame 22 are permanently fixed by the screw 622a, and then further fixed by additional fixing screws 622b and 622c.

Next, the procedure for erecting the glass panel 41 into the FIX section 4 and fixing the mullions 3 to the upper frame 21 and lower frame 22 will be described. First, as shown in the upper diagram of Figure 11A, the mullions 3 are temporarily fixed with screws 612a and 622a. Then, as shown in the middle diagram of Figure 11A, they are retracted from the glass panel 41. Finally, as shown in the lower diagram of Figure 11A, the end of the glass panel 41 on the vertical frame 24 side of the FIX section 4 is positioned 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 towards the glass panel 41 to position it in the left-right direction.

Then, with the mullion 3 positioned in the predetermined left-right position, the screws 612a and 622a are permanently fixed as shown in the lower diagram of Figure 11B, and the guide section (upper guide section 61, lower guide section 62) and the frame 2 (upper frame 21, lower frame 22) are fixed together with additional fixing screws 612b, 612c, 622b, and 622c.

Next, as shown in the lower diagram of Figure 11B, the exterior side X1 of the end of the glass panel 41 on the vertical frame 24 side is pressed with the trim strip 245, and the outer sash 5 is erected on the exterior side X1 of the opening 25 of the frame 2. In this way, a fixed section 4 is formed in the joinery 1, and the outer sash 5 can be positioned in the opening 25 of the frame 2.

As described above, by configuring the mullions 3 to be movable in the left-right direction, the glass panels 41 can be erected with gaps in the left-right direction, thus facilitating the installation of the glass panels 41.

The mullions 3 described above are configured to be movable in the left-right direction and are fixed to the upper frame 21 and lower frame 22 at predetermined positions in the left-right direction. Therefore, considering that the mullions 3 are movable in the left-right direction, it is necessary to ensure the watertight performance of the mullions 3 at their upper and lower ends. Accordingly, in this embodiment, a watertight structure as shown in Figures 12 to 19 is provided at the upper and lower ends of the mullions 3 to ensure watertight performance between them and the frame 2.

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

In detail, as shown in Figure 12, the upper end of the mullion 3 is positioned in close contact with a watertight component located in the gap between the indoor surface cover 212b of the FIX-side upper frame and the indoor surface cover 212a of the sash-side upper frame, and with a watertight component located in the gap between the indoor lower end cover 213b of the FIX-side upper frame and the indoor lower end cover 213a of the sash-side upper frame, in the left-right direction. As shown in Figure 16, the lower end of the mullion 3 is positioned in close contact with a watertight component located in the gap between the indoor surface cover 222b of the FIX-side lower frame and the indoor surface cover 222a of the sash-side lower frame, and with a watertight component located in the gap between the indoor upper end cover 223b of the FIX-side lower frame and the indoor upper end cover 223a of the sash-side lower frame, in the left-right direction.

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 positioned 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 positioned in the upper frame indoor-side groove 211b of the upper frame 21.

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

The upper watertight member 71 on the upper frame side is installed with the watertight sealing material 711a in contact with the lower surface of the upper frame 21, the watertight sealing material 711b in contact with the mullion 3, and also in contact with the end faces 212c and 213c of the longitudinal ends of the indoor surface cover 212a and the indoor lower end cover 213a of the upper frame on the sash side of the upper frame 21, and the watertight sealing material 711c in contact with the end faces 212d and 213d of the longitudinal ends of the indoor surface cover 212b and the indoor lower end cover 213b of the upper frame on the FIX side of the upper frame 21. This improves the watertight and airtight performance between the upper end of the mullion 3 and the upper frame 21.

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

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

The lower watertight member 72 on the lower frame side is installed with the watertight sealing material 721a in contact with the upper surface of the lower frame 22, the watertight sealing material 721b in contact with the mullion 3, and also in contact with the end faces 222c and 223c of the longitudinal ends of the indoor surface cover 222a and the indoor upper end cover 223a of the lower frame on the sash side of the lower frame 22, and the watertight sealing material 721c in contact with the end faces 222d and 223d of the longitudinal ends of the indoor surface cover 222b and the indoor upper end cover 223b of the lower frame on the FIX side of the lower frame 22. This improves the watertight and airtight performance between the upper end of the mullion 3 and the lower frame 22.

Next, we will explain the structure provided from a security standpoint. As shown in Figure 5, the door 1 of this embodiment is a so-called externally movable type, where the outer sash 5 is positioned to move left and right on the exterior side X1 of the FIX section 4. When the outer sash 5 is in the closed position, the vertical frame 54, located on the tail end side of the outer sash 5, is positioned on the exterior side X1 of the mullion 3, and when viewed from both the interior and exterior, it overlaps with the mullion 3.

As shown in Figures 4 and 5, the retaining strips 35, 215, 225, and 245 that press against the outer edge of the glass panel 41 on all four sides of the FIX section 4 are pressed against the indoor side X2 of the FIX glass placement groove 31 of the mullion 3 by the retaining strip 35, and are also pressed against the FIX-side attachments 214, 224, and 244 fixed to the indoor side X2 of the upper frame 21, lower frame 22, and vertical frame 24, respectively, by the retaining strips 215, 225, and 245.

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

The upper glazing edge 215, lower glazing edge 225, vertical glazing edge 35 on the mullion side, and vertical glazing edge 245 on the vertical frame side are arranged along the four sides formed by the upper frame 21, lower frame 22, mullion 3, and vertical frame 24. In this embodiment, the upper glazing edge 215, lower glazing edge 225, vertical glazing edge 35 on the mullion side, and vertical glazing edge 245 on the vertical frame side constitute a four-sided glazing edge that presses against the glass panel 41 on the four sides formed by the upper frame 21, lower frame 22, mullion 3, and vertical frame 24.

On one side (the side of the vertical frame 3) of the four-sided trim (upper trim 215, lower trim 225, vertical trim 35 on the vertical frame side, and vertical trim 245 on the vertical frame side), the longitudinal end of the upper trim 215 is positioned above the longitudinal upper end of the vertical trim 35 on the vertical frame side, and the longitudinal end of the lower trim 225 is positioned below the longitudinal lower end of the vertical trim 35 on the vertical frame side, thus forming a so-called horizontally dominant structure.

On the other side (vertical frame 24 side) of the four-sided trim (upper trim 215, lower trim 225, vertical trim 35 on the vertical frame side, and vertical trim 245 on the vertical frame side), the longitudinal end of the upper trim 215 is positioned on the inner circumference in the left-right direction of the longitudinal upper end of the vertical trim 245 on the vertical frame side, and the longitudinal end of the lower trim 225 is positioned on the inner circumference in the left-right direction of the longitudinal lower end of the vertical trim 245 on the vertical frame side, thus forming a so-called vertically dominant structure.

Here, the trim pieces (upper trim piece 215, lower trim piece 225, vertical trim piece 35 on the mullion side, and vertical trim piece 245 on the vertical frame side) are attached to the inner circumference of the mullion 3, upper frame 21, lower frame 22, and vertical frame 24. Therefore, to remove the trim pieces (upper trim piece 215, lower trim piece 225, vertical trim piece 35 on the mullion side, and vertical trim piece 245 on the vertical frame side) attached to the inner circumference of the mullion 3, upper frame 21, lower frame 22, and vertical frame 24, it is necessary to move them further inward from the inner circumference of the mullion 3, upper frame 21, lower frame 22, and vertical frame 24.

In this embodiment, when removing the upper trim 215, lower trim 225, vertical trim 35 on the mullion side (one side), and vertical trim 245 on the vertical frame side (the other side), first, the vertical trim 35 on the mullion side is removed from the mullion 3. Then, the upper trim 215 is removed from the upper frame 21, and the lower trim 225 is removed from the lower frame 22. After that, the vertical trim 245 on the vertical frame side is removed from the vertical frame 24, thereby allowing the upper trim 215, lower trim 225, vertical trim 35 on the mullion side (one side), and vertical trim 245 on the vertical frame side (the other side) to be removed.

In this embodiment, when the vertical trim 35 on the mullion side is not removed from the mullion 3, attempting to move the upper trim 215 and lower trim 225 towards the inner circumference of the mullion 3, upper frame 21, lower frame 22, and vertical frame 24 is impossible because the vertical trim 35 obstructs the removal of the upper trim 215 and lower trim 225. Similarly, attempting to move the vertical trim 245 on the vertical frame side towards the inner circumference of the mullion 3, upper frame 21, lower frame 22, and vertical frame 24 is impossible because the upper trim 215 and lower trim 225 obstruct the removal of the vertical trim 245. Therefore, when removing the upper trim 215, lower trim 225, the vertical trim 35 on the mullion side, and the vertical trim 245 on the vertical frame side, it is necessary to first remove the vertical trim 35 on the mullion side from the mullion 3.

Here, as shown in Figures 5 and 20, the vertical frame 54 of the outer sash 5 is positioned on the outdoor side X1 of the vertical trim 35 on the mullion side when the outer sash 5 is in the closed position. Therefore, on one side (the mullion 3 side) of the four-sided trim (upper trim 215, lower trim 225, mullion side vertical trim 35, and vertical frame side vertical trim 245), when the outer sash 5 is in the closed position, the mullion side vertical trim 35 is positioned covered by the vertical frame 54 of the outer sash 5.

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

Therefore, by locking the outer sash 5 while it is in the closed position, the vertical trim 35 on the mullion side cannot be removed from the exterior side X1. Consequently, the upper trim 215, lower trim 225, and vertical trim 245 on the vertical frame side also cannot be removed. This prevents the removal of the four-sided trim (upper trim 215, lower trim 225, vertical trim 35 on the mullion side, and vertical trim 245 on the vertical frame side), and thus prevents the removal of the glass panel 41. Therefore, security performance can be improved.

Conventionally, when a door or window 1 is configured as a so-called externally movable type, where the outer sash 5 is positioned to move horizontally on the exterior side X1 of the fixed section, if both ends of the four-sided trim are configured with a vertically dominant structure, it is possible to move the upper trim 215 and the lower trim 225 inwards in the vertical direction from the exterior side X1. Furthermore, if both ends of the four-sided trim are configured with a horizontally dominant structure, it is possible to move one vertical trim and the other vertical trim inwards in the horizontal direction from the exterior side X1. Therefore, conventionally, when the trim could be removed from the exterior side X1, glass fastening brackets were provided on the glass panel for security reasons.

In contrast, in this disclosure, one side of the four-sided trim (upper trim 215, lower trim 225, vertical trim 35 on the mullion side, and vertical trim 245 on the vertical frame side) is configured with a so-called horizontally dominant structure, while the other side of the four-sided trim (upper trim 215, lower trim 225, vertical trim 35 on the mullion side, and vertical trim 245 on the vertical frame side) is configured with a so-called vertically dominant structure. Therefore, in the four-sided trim, the vertical trim (vertical trim 35) in the portion configured with the so-called horizontally dominant structure must be removed first before the other trims can be removed. Furthermore, when the outer sash 5 is closed and locked, on the exterior side X1, the vertical frame 54 of the outer sash 5 covers the vertical trim 35 on the mullion side, preventing its removal, thus improving security performance.

According to the first embodiment, the following effects are achieved. The joinery 1 of this embodiment is attached to the upper frame 21, lower frame 22, mullion 3, and vertical frame 24, and includes an upper pressing edge 215, a lower pressing edge 225, a mullion-side vertical pressing edge 35, and a vertical frame-side vertical pressing edge 245 that press against one side of the end of the glass panel 41. On one side in the left-right direction, the longitudinal end of the upper pressing edge 215 is positioned above the longitudinal upper end of the mullion-side vertical pressing edge 35, and the longitudinal end of the lower pressing edge 225 is positioned below the longitudinal lower end of the mullion-side vertical pressing edge 35. On the other side in the left-right direction, the longitudinal end of the upper pressing edge 215 is positioned on the inner circumference of the longitudinal upper end of the vertical frame-side vertical pressing edge 245, and the longitudinal end of the lower pressing edge 225 is positioned on the inner circumference of the longitudinal lower end of the other side vertical pressing edge 245.

As a result, the upper and lower trims 215 and 225 cannot be removed unless the vertical trim 35 on the mullion side is removed from the mullion 3, and therefore the glass panel 41 cannot be removed. Thus, by designing the vertical trim 35 on the mullion side to be inremovable from the mullion 3, and making only the vertical trim 35 inremovable, the removal of the glass panel 41 can be prevented, thereby improving security.

Furthermore, in this embodiment, the vertical trim 35 on the mullion side is positioned so that it is covered by the vertical frame 54 of the outer sash 5. Because the vertical trim 35 on the mullion side is covered by the vertical frame 54 of the outer sash 5, it cannot be removed. Therefore, the security performance can be improved.

Next, the second embodiment will be described. For points not described in the second embodiment, the description of the first embodiment can be referenced. In the second embodiment, components similar to those in the first embodiment are given the same reference numerals as in the first embodiment, and their descriptions are omitted.

In the second embodiment, the glazing bead of the FIX section 4 is a three-sided glazing bead, as shown in Figure 21, whereas the glazing bead of the FIX section 4 in the first embodiment is a four-sided glazing bead. In the second embodiment, the vertical frame 24 and the vertical frame-side vertical glazing bead 245 shown in Figure 20 of the first embodiment are not provided. The upper glazing bead 215, lower glazing bead 225, and vertical glazing bead 35 of the second embodiment constitute a three-sided glazing bead that presses against the glass panel 41 on three sides formed by the upper frame 21, lower frame 22, and mullion 3.

On one side (the side of the vertical post 3) of the three-sided trim (upper trim 215, lower trim 225, and vertical trim 35 on the vertical post side), the longitudinal end of the upper trim 215 is positioned above the longitudinal upper end of the vertical trim 35 on the vertical post side, and the longitudinal end of the lower trim 225 is positioned below the longitudinal lower end of the vertical trim 35 on the vertical post side, thus forming a structure where the horizontal orientation is dominant.

On the other side in the left-right direction of the three-sided trim (upper trim 215, lower trim 225, and vertical trim 35 on the vertical side), vertical trim is not provided at the other end of the upper trim 215 and lower trim 225 in the left-right direction, resulting in an open end.

In the second embodiment, where the upper trim 215, lower trim 225, and vertical trim 35 on the mullion side constitute a three-sided trim, similar to the first embodiment, the other trims cannot be removed unless the vertical trim (vertical trim 35) in the portion configured in a so-called horizontally dominant structure is removed first. Also, similar to the first embodiment, when the outer sash 5 is closed and locked, on the exterior side X1, the vertical frame 54 of the outer sash 5 covers the vertical trim 35 on the mullion side, preventing its removal, thus improving security.

According to the second embodiment, the following effects are achieved. The joinery 1 of this embodiment is attached to the upper frame 21, lower frame 22, and mullion 3, and includes an upper pressing edge 215, a lower pressing edge 225, and a mullion-side vertical pressing edge 35 that press against one side of the end of the glass panel 41. The upper pressing edge 215, lower pressing edge 225, and mullion-side vertical pressing edge 35 are arranged along the three sides formed by the upper frame 21, lower frame 22, and mullion 3. On one side in the left-right direction, the longitudinal end of the upper pressing edge 215 is positioned above the longitudinal upper end of the mullion-side vertical pressing edge 35, and the longitudinal end of the lower pressing edge 225 is positioned below the longitudinal lower end of the mullion-side vertical pressing edge 35.

As a result, similar to the first embodiment, the upper and lower trims 215 and 225 cannot be removed unless the vertical trim 35 on the mullion side is removed from the mullion 3, and therefore the glass panel 41 cannot be removed. Thus, by creating a structure that prevents the vertical trim 35 on the mullion side from being removed from the mullion 3, removal of the glass panel 41 can be prevented, thereby improving security.
