[0007] The embodiments of the present invention will now be described based on the drawings. Figures 1 to 5 show one embodiment of the joinery of the present invention. This joinery is applied to a sliding sash for a building, and as shown in Figures 1, 3, and 4, it comprises a frame 8 attached to an opening in the building's structural frame, an outer sash 9a and an inner sash 9b housed within the frame 8 so as to be able to open and close in a sliding manner, and a screen door 3 provided on the exterior side of the outer sash 9a so as to be able to move left and right. As shown in Figures 1 and 4, in this fixture, the outer sash 9a protrudes outward from the frame 8, and therefore the screen door 3 is installed on the outside of the frame 8.

[0008] As shown in Figures 1, 3, and 4, frame 8 is constructed by framing an upper frame 1, a lower frame 10, and left and right vertical frames 11, 11, all of which are made from extruded aluminum alloy profiles. As shown in Figures 1 and 2, the upper frame 1 has a hanging piece 12 at its outdoor end, and an upper frame auxiliary member 2 is fixed to the inner circumferential edge of the hanging piece 12, protruding outwards. As shown in Figures 3 and 4, the upper frame auxiliary member 2 is provided along the entire length of the upper frame 1 and is divided into three parts (2a, 2b, 2c) in the longitudinal direction. Of the three parts, the central one 2b is short, while the left and right parts 2a and 2c are the same length and are significantly longer than the central one 2b.

[0009] The upper frame support member 2 is made of an extruded aluminum alloy profile and, as shown in Figure 2, has an upper wall 13 and a lower wall 14, a hanging piece 6 that hangs down from the outdoor end of the upper wall 13, a rising piece 7 that rises up from the outdoor end of the lower wall 14, an indoor wall 15 that connects the upper wall 13 and the lower wall 14 on the indoor side, and a mounting portion 16 that is provided continuously on the indoor side of the lower wall 14 and is located on the indoor side of the indoor wall 15. The rising piece 7 is located approximately in the center of the upper wall 13 in the indoor-outdoor direction, and a gap 17 is formed between the hanging piece 6 and the rising piece 7. The mounting portion 16 has an upward-opening groove 18, and within the groove 18 is a projection 19 that engages with a recessed groove 36 formed on the indoor side surface of the hanging piece 12 of the upper frame 1, and a projection 20 that engages with the outdoor side of the tip of the hanging piece 12 of the upper frame 1. The upper frame support member 2 is attached by fitting the groove 18 of the mounting part 16 into the hanging piece 12 of the upper frame 1 from the inner circumference side, engaging the two protrusions 19 and 20 provided in the groove 18 with the indoor and outdoor sides of the hanging piece 12 of the upper frame 1, respectively, and then screwing the screw 21, which is inserted into the mounting part 16 from the inner circumference side, into the gap between the hanging piece 12 of the upper frame 1 and the indoor side wall 15 of the upper frame support member 2, thereby fixing it to the inner circumference end of the hanging piece 12 of the upper frame 1. The screw 21 is a self-tapping screw. As shown in Figure 2, the upper frame support member 2 is attached with a gap between it and the outer wall 22.

[0010] As shown in Figure 4, the vertical frame 11 has a vertical frame auxiliary member 24 that protrudes outward from the inner circumferential edge of the exterior-facing wall 23, and the edge of the screen door 3 is positioned to contact the vertical frame auxiliary member 24. The vertical frame auxiliary member 24 is made of an extruded aluminum alloy profile and, like the upper frame auxiliary member 2, has a groove-shaped mounting portion 25 on the interior side. The groove of the mounting portion 25 is fitted into the exterior-facing wall 23 of the vertical frame 11 from the inner circumferential side, and a screw 26 inserted into the mounting portion 25 from the inner circumferential side is screwed into the gap on the exterior side of the exterior-facing wall 23 of the vertical frame 11, thereby fixing and attaching it to the inner circumferential edge of the exterior-facing wall 23 of the vertical frame 11.

[0011] As shown in Figure 1, the lower frame 10 has a screen door rail 27 protruding upward from its exterior end, and a roller 29 attached to the lower frame 28 of the screen door 3 engages with the screen door rail 27.

[0012] As shown in Figures 1, 3, and 4, the screen door 3 is constructed by assembling an upper frame 30, a lower frame 28, and left and right vertical frames 31, 31, which are made of extruded aluminum alloy profiles, and stretching a screen 32 inside. A resin sway stopper 4 (see Figure 2) is attached to the upper end of the vertical frame 31. The sway stopper 4 has a groove 33 formed in it that accommodates the hanging piece 6 of the upper frame auxiliary material 2. By accommodating the hanging piece 6 of the upper frame auxiliary material 2 in the groove 33, the upper part of the screen door 3 is guided along the longitudinal direction of the upper frame 1 while restricting its movement in the in-room and out-of-room direction. As shown in Figure 2, the upper frame 30 has an engagement portion 5 integrally formed on the upper part on the interior side for engagement with the upper frame auxiliary member 2. The engagement portion 5 is located on the interior side of the brace 4 and is formed in a downwardly hooked shape between the facing wall 34 and the hanging wall 35. The engagement portion 5 is spaced apart from the rising piece 7 and the lower wall 14 of the upper frame auxiliary member 2 in the vertical and interior-exterior directions. As shown in Figure 9, the engagement part 5 is provided on the upper frame 30 of the screen door 3, so that no matter how the upper frame 30 moves, it will not come off the upper frame support member 2. Therefore, even if resin parts such as the anti-sway device 4 and the rollers 29 are burned or damaged in a fire, the screen door 3 will not fall.

[0013] This joinery is designed so that, under normal use, the sliding of the screen door 3 is not adversely affected. However, if the screen door 3 is lifted up by strong winds or the like, and the roller 29 attached to the bottom frame 28 of the screen door 3 comes off the screen door rail 27 of the bottom frame 10, the engaging part 5 of the screen door 3 catches on the rising piece 7 of the upper frame auxiliary member 2, as shown in Figure 5, thereby preventing the screen door 3 from falling. Note that Figure 5 shows the screen door in a state where the brace 4 is missing. The brace 4 may be damaged due to aging of the resin or repeated wind loads, and if the brace 4 is lost due to damage, the rattling of the top of the screen door 3 will increase. However, as shown in the figure, even if the brace 4 is lost, the engaging part 5 will not come off the upper frame support member 2, and the screen door 3 can be prevented from falling. Furthermore, this joinery prevents the screen door 3 from falling by having the engaging portion 5 of the screen door 3 catch on the rising piece 7 of the upper frame auxiliary material 2, and the hanging piece 6 of the upper frame auxiliary material 2 lock onto the interior side of the upper frame 30 of the screen door 3 (see Figures 5 and 9), thus more reliably preventing the screen door 3 from falling.

[0014] Next, we will explain the procedure for installing the upper frame support material 2 and the screen door 3. First, as shown in Figures 6(a) and 7, attach one of the three upper frame support materials 2a, 2b, and 2c, either the left or right upper frame support material 2a, to the hanging piece 6 of the upper frame 1. To install the upper frame support member 2a, as shown in Figure 7(a), the groove 18 of the mounting part 16 is fitted into the hanging piece 12 of the upper frame 1 from the inner circumference with the mounting part 16 tilted so that the indoor side is lower, and then, as shown in Figure 7(b), the upper frame support member 2a is rotated so that it is tilted outwards. Then, as shown in Figure 7(c), the protrusions 19 and 20 provided in the groove 18 engage with the indoor side of the hanging piece 12 of the upper frame 1, and the upper frame support member 2a is held to some extent by the hanging piece 12 of the upper frame 1. In this state, as shown in Figure 7(d), the screw 21 inserted into the mounting part 16 from the inner circumference is screwed into the gap between the hanging piece 12 of the upper frame 1 and the indoor side wall 15 of the upper frame support member 2, thereby fixing the upper frame support member 2a to the hanging piece 12 of the upper frame 1. Once one of the upper frame auxiliary members 2a on either the left or right side is installed, as shown in FIGS. 6(a) and (b), with the door wheel 29 of the lower frame 28 engaged with the screen door rail 27 of the lower frame 10 (see FIG. 1), while sliding the screen door 3 horizontally, insert the engaging portion 5 of the upper frame 30 into the gap 17 of the upper frame auxiliary member 2a (see FIG. 2) from the small end, and install the screen door 3 between the upper and lower frames 1 and 10. Next, as shown in FIG. 6(b), install the central upper frame auxiliary member 2b. When installing the central upper frame auxiliary member 2b, with the mounting portion 16 engaged with the inner peripheral side edge of the hanging piece 12 of the upper frame 1, slide the upper frame auxiliary member 2b toward the screen door 3 side to pass the engaging portion 5 of the screen door 3 through the upper frame auxiliary member 2b, and then fix the upper frame auxiliary member 2b with a screw 21 from the inner peripheral side (see FIG. 2). After that, as shown in FIGS. 6(c) and (d), install the other upper frame auxiliary member 2c in the same manner as the previously installed upper frame auxiliary member 2a.

[0015] The upper frame auxiliary member 2 can also be provided in two left - right divided parts. FIG. 8 shows the installation procedure of the upper frame auxiliary member 2 and the screen door 3 when the upper frame auxiliary member 2 is divided into two left - right parts 2a and 2b. One of the upper frame auxiliary members 2a, 2b (the right - hand side in the figure) is shorter than the other 2b. First, as shown in FIG. 8(a), install the shorter upper frame auxiliary member 2a in the same manner as in the case of the three - divided one described above. Then, as shown in FIG. 8(b), install the screen door 3 by passing the engaging portion 5 through the upper frame auxiliary member 2a from the small end. Next, as shown in FIGS. 8(c) and (d), with the other upper frame auxiliary member 2b tilted so that the end on the screen door 3 side is upward, pass the engaging portion 5 of the screen door 3 through the upper frame auxiliary member 2b, and then rotate it so that the upper frame auxiliary member 2b becomes horizontal, insert the hanging piece 12 of the upper frame 1 into the groove 18 of the mounting portion 16, and fix it with a screw 21 from the inner peripheral side.

[0016] <Figure 10 shows another embodiment of the engaging portion 5 provided on the upper frame 30 of the screen door 3. In this embodiment, the engaging portion 5 is formed by a component 37 that is formed separately from the upper frame 30. This component 37 is formed by bending a metal plate such as stainless steel and is attached by contacting the outer surface of the inner wall 38 of the upper frame 30 and fixing it with screws 39. Multiple such components 37 are provided at intervals along the longitudinal direction of the upper frame 30 (for example, two near the left and right ends). In this way, by forming the engaging portion 5 with a separate part 37 from the upper frame 30 of the screen door 3, the upper frame 30 of the screen door 3 can be used interchangeably with a normal upper frame 30 of a screen door 3 that does not have the engaging portion 5.

[0017] As described above, this joinery comprises an upper frame 1, an upper frame auxiliary member 2 provided on the exterior side of the upper frame 1, and a screen door 3. The screen door 3 has a sway stopper 4 and an engaging part 5 located on the interior side of the sway stopper 4. The upper frame auxiliary member 2 has a hanging piece 6 that engages with the sway stopper 4 of the screen door 3, and a rising piece 7 that is spaced apart from the engaging part 5 of the screen door 3 in the vertical and interior / exterior directions. When the screen door 3 comes off the lower frame 10, the engaging part 5 of the screen door 3 catches on the rising piece 7 of the upper frame auxiliary member 2, preventing the screen door 3 from falling (see Figure 5). Thus, it is possible to reliably prevent the screen door 3 from coming off the frame 8 and falling due to strong winds or the like. The upper frame support member 2 is divided into multiple sections in the longitudinal direction, which allows the screen door 3 to be slid horizontally and the engaging portion 5 of the screen door 3 to engage with the end of the upper frame support member 2 (see Figures 6 and 8), thus making it easy to install the screen door 3. Since the upper frame support member 2 is attached from the inner side to the inner edge of the hanging piece 12 at the exterior end of the upper frame 1 (see Figure 7), the upper frame support member 2 can be attached to the upper frame 1 after the frame 8 has been fixed to the building structure and the exterior wall 22 has been constructed, resulting in good workability. Furthermore, this fixture prevents the screen door 3 from falling by having the engaging portion 5 of the screen door 3 catch on the rising piece 7 of the upper frame auxiliary material 2, and the hanging piece 6 of the upper frame auxiliary material 2 lock onto the interior side of the upper frame 30 of the screen door 3 (see Figures 5 and 9), thus providing even more reliable protection against the screen door 3 falling.

[0018] The present invention is not limited to the embodiments described above. The cross-sectional shape and material of the upper frame and upper frame support material can be changed as appropriate. The shape and material of the engaging part of the screen door can be changed as appropriate. The method of attaching the upper frame support material and screen door is not limited. The present invention is not limited to sliding sashes, but can also be applied to single-sliding sashes, etc. [Explanation of symbols]
