The following describes an embodiment of the present invention with reference to the drawings. Figures 1 to 4 show one embodiment of the fitting of the present invention. This fitting is applied to a sliding sash for a building, and as shown in Figures 2 and 3, it comprises a frame 8 attached to an opening in the building's framework, an outer screen 7a and an inner screen 7b housed within the frame 8 in a sliding manner so that they can be opened and closed freely, a screen door 4 installed outside the outer screen 7a so that it can move freely left and right, and a grille 49 attached to the outside of the frame 8.

As shown in Figures 2 and 3, the frame 8 is composed of an upper frame 9, a lower frame 10, and left and right vertical frames 1, 1. As shown in Figure 1, the vertical frame 1 has a rib 11 that protrudes slightly toward the interior of the room on the inner peripheral edge of the exterior facing wall 3, and a protrusion (regulating portion) 6 that protrudes slightly toward the interior of the room at a position spaced from the rib 11 on the outer peripheral side. The protrusion 6 has an inclined surface 12 on the inner peripheral side, and the outer peripheral side surface 13 is formed at a right angle to the exterior facing wall 3.

As shown in Figures 2 and 3, the outer screen 7a and the inner screen 7b are constructed by assembling an upper frame 14, a lower frame 15, a door end frame 16, and a joint frame 17, with glass (laminated glass) 18 placed inside. The outer screen 7a and the inner screen 7b have a large glass-swallowing groove 19 to accommodate the thick glass 18, so the outer screen 7a protrudes outside the frame 8.

As shown in Figures 2 and 3, the screen door 4 is constructed by assembling an upper frame 20, a lower frame 21, and left and right vertical frames 22, 22 together, with a screen 23 stretched on the inside. The screen door 4 is extended to the outside of the frame 8 so as not to interfere with the outer screen 7a, and is guided by a hanging piece 24 formed on the outside end of the upper frame 9 and a screen door rail 25 formed on the outside end of the lower frame 10, allowing it to slide along the longitudinal direction of the upper and lower frames 9, 10.

In order to prevent insects from entering through the gap between the vertical frame 1 and the vertical stile 22 of the screen door 4 that is brought out to the outside of the room, as shown in Figure 2, a vertical frame auxiliary material 2 is attached to the exterior wall 3 of the vertical frame 1, and mohair 26 attached to the outer peripheral edge of the vertical stile 22 of the screen door 4 abuts against the vertical frame auxiliary material 2.
The vertical frame auxiliary material 2 is made of an extruded aluminum alloy profile and, as shown in Figure 1, has a projection wall 27, an indoor side wall 28, an outdoor side wall 29 and an intermediate wall 30. Between the indoor side wall 28 and the intermediate wall 30, a building gutter 31 located on the building side in the projection direction is formed so as to be open toward the outer periphery, and between the outdoor side wall 29 and the intermediate wall 30, an anti-building gutter 32 located on the opposite side to the building in the projection direction is formed so as to be open toward the outer periphery.
A protrusion 33 is formed in the building gutter 31 on the outer circumferential side of the blind wall 27. The blind wall 3 of the vertical frame 1 is inserted into the building gutter 31 of the vertical frame reinforcement material 2 in a manner that follows the outer side of the indoor side wall 28, and the inner circumferential end of the blind wall 3 is inserted between the protrusion 33 of the vertical frame reinforcement material 2 and the indoor side wall 28. In addition, a rib 34 is formed at the outer circumferential end of the indoor side wall 28 of the vertical frame reinforcement material 2, protruding toward the outside of the room, and the rib 34 engages with the protrusion 6 of the blind wall 3 of the vertical frame 1, thereby restricting the left-right movement of the vertical frame reinforcement material 2.
In addition, the vertical frame reinforcement material 2 has a protrusion 35 formed within the anti-building gutter 32 on the outer peripheral side of the projection wall 27, a rib 36 is formed at the outer peripheral end of the exterior wall 29 protruding toward the inside of the room, and a rib 37 is formed at the outer peripheral end of the intermediate wall 30 protruding toward the outside.

As shown in Fig. 4, the vertical frame reinforcement material 2 has resin parts 5 attached to at least two places, the upper and lower parts. The resin parts 5 are piece-shaped parts made of hard resin, and serve to fix the vertical frame reinforcement material 2 to the visible wall 3 of the vertical frame 1. As shown in Fig. 1, the resin parts 5 have a restricting portion 38 that is inserted into the building gutter 31 of the vertical frame reinforcement material 2, and a retaining portion 39 that is inserted into the anti-building gutter 32. A groove 40 with a substantially circular cross section is formed on the inner periphery of the connecting portion between the restricting portion 38 and the retaining portion 39.
The restricting portion 38 has a recess 41 on the inner periphery side to allow the protrusion 33 of the vertical frame reinforcement material 2 to escape, and a 45° inclined surface 42 is formed on the outer periphery side. The indoor side surface 43 of the restricting portion 38 is slightly inclined toward the indoor side as it approaches the outer periphery side. The restricting portion 38 is pressed into the gap between the visible wall 3 of the vertical frame 1 and the intermediate wall 30 of the vertical frame reinforcement material 2 in a compressed state in the prospective direction, and a position (position where the protrusion 6 is provided) spaced from the inner periphery end of the visible wall 3 of the vertical frame 1 to the outer periphery side is clamped between the indoor side wall 28 of the vertical frame reinforcement material 2 and the restricting portion 38 of the resin part 5. This restricts the movement of the vertical frame reinforcement material 2 in the prospective direction, and the vertical frame reinforcement material 2 is fixed to the visible wall 3 of the vertical frame 1 so as not to wobble.
The anti-slip portion 39 engages with the protrusion 35 and ribs 36, 37 in the anti-building gutter 32 of the vertical frame reinforcement material 2 and fits into the anti-building gutter 32, thereby preventing the resin part 5 from coming off the vertical frame reinforcement material 2.

Although it would be sufficient to fix the vertical frame reinforcement material 2 only with the resin part 5 described above, as shown in FIG. 4, the upper and lower ends of the vertical frame reinforcement material 2 are fixed with screws (tapping screws) 44 just to be sure. The screws 44 are passed through holes (not shown) formed in the front wall 27 of the vertical frame reinforcement material 2 from the inner periphery side, and are screwed into the gap between the front wall 3 of the vertical frame 1 and the intermediate wall 30 of the vertical frame reinforcement material 2, similar to the screws 46 for mounting the grille mounting bracket 45 described later (see FIG. 1). In this way, by screwing the screws 44 into the gap between the front wall 3 of the vertical frame 1 and the intermediate wall 30 of the vertical frame reinforcement material 2, the vertical movement of the vertical frame reinforcement material 2 is restricted, and the vertical frame reinforcement material 2 can be firmly fixed to the front wall 3 of the vertical frame 1.

Next, the procedure for attaching the vertical frame reinforcement material 2 to the visible wall 3 of the vertical frame 1 will be described. First, the resin part 5 is attached to a predetermined position in the longitudinal direction of the vertical frame reinforcement material 2. To attach the resin part 5, as shown by the arrow in Fig. 5(a), the restricting portion 38 side is pushed with a finger into the building gutter 31 of the vertical frame reinforcement material 2, and then as shown by the arrow in Fig. 5(b), the retaining portion 39 side is pushed with a finger into the anti-building gutter 32 to fit it in, and the resin part 5 is attached in the state shown in Fig. 5(c).
Then, as shown in Figure 6 (a), with the vertical frame reinforcement material 2 tilted outward, the inner end of the visible wall 3 of the vertical frame 1 is placed between the regulating portion 38 of the resin part 5 and the indoor side wall 28, and the vertical frame reinforcement material 2 is rotated inwardly while fitting the inner end of the visible wall 3 of the vertical frame 1 between the regulating portion 38 of the resin part 5 and the indoor side wall 28.
When the rib 34 of the interior side wall 28 of the vertical frame reinforcement material 2 clears the rib 11 of the visible wall 3 of the vertical frame 1, the vertical frame reinforcement material 2 is pushed firmly toward the outer periphery as shown in Figure 6 (b).
Then, as shown in Figure 6 (c), the rib 34 of the indoor side wall 28 of the vertical frame reinforcement material 2 overcomes the protrusion 6 of the visible wall 3 of the vertical frame 1, restricting the left-right movement of the vertical frame reinforcement material 2, and at the same time, the visible wall 3 of the vertical frame 1 is clamped between the indoor side wall 28 of the vertical frame reinforcement material 2 and the regulating part 38 of the resin part 5, restricting the movement of the vertical frame reinforcement material 2 in the visible direction, and the vertical frame reinforcement material 2 is fixed to the visible wall 3 of the vertical frame 1.

As shown in Figures 2 and 4, the grille 49 is attached to a grille mounting bracket 45 attached to the vertical frame reinforcement material 2. As shown in Figure 1, the grille mounting bracket 45 has a mounting section 47 bent into an approximately L-shape at the indoor end so as to abut the interior wall 27 and the exterior wall 29 of the vertical frame reinforcement material 2, and a locking section 48 that locks to the outer periphery of the outdoor end of the vertical frame reinforcement material 2. The grille mounting bracket 45 is attached to the vertical frame reinforcement material 2 by inserting a screw (tapping screw) 46 inserted from the inner periphery into the mounting section 47 and threading it into the gap between the exterior wall 3 of the vertical frame 1 and the intermediate wall 30 of the vertical frame reinforcement material 2. By attaching the grille mounting bracket 45 to the vertical frame reinforcement material 2 in this way, the grille 49 can be attached in addition to the screen door 4.

As described above, this fixture comprises a vertical frame 1 and a vertical frame auxiliary member 2. The vertical frame 1 has a restricting portion (protrusion) 6 on the inner edge of the exterior-facing visible wall 3 that restricts the left-right movement of the vertical frame auxiliary member 2. The vertical frame auxiliary member 2 is against which the end of the screen door 4 abuts and has a plastic part 5 attached. The vertical frame auxiliary member 2 is fitted into the exterior-facing wall 3 of the vertical frame 1 from the inner side, and the plastic part 5 is positioned on the exterior side of the exterior-facing wall 3 of the vertical frame 1 to restrict the movement of the vertical frame auxiliary member 2 in the forward direction. As a result, the screen door 4 can be attached even if the shoji screen 7a protrudes beyond the frame 1 to the outside, and the vertical frame auxiliary member 2 can be easily attached by simply fitting it into the exterior-facing wall 3 of the vertical frame 1 from the inner side, making it easy to install.
The vertical frame reinforcement material 2 has a building gutter 31 located on the building side in the projection direction, and the resin part 5 has a regulating part 38 inserted into the building gutter 31. By clamping the visible wall 3 of the vertical frame 1 between the indoor side wall 28 of the vertical frame reinforcement material 2 and the regulating part 38 of the resin part 5, the vertical frame reinforcement material 2 can be easily and securely attached to the visible wall 3 of the vertical frame 1.
In addition, this building fixture clamps a position spaced from the inner periphery end of the visible wall 3 of the vertical frame 1 toward the outer periphery between the indoor side wall 28 of the vertical frame reinforcement material 2 and the resin part 5, thereby preventing the outdoor side of the vertical frame reinforcement material 2 from swinging in the inner or outer periphery direction and allowing the vertical frame reinforcement material 2 to be fixed more firmly.
The vertical frame auxiliary material 2 has an anti-building gutter 32 on the side opposite the building in the prospective direction, and the resin part 5 has a slip-out prevention portion 39 that fits into the anti-building gutter 32 to prevent it from slipping out.Therefore, the vertical frame auxiliary material 2 can be attached to the visible wall 3 of the vertical frame 1 with the resin part 5 already attached to the vertical frame auxiliary material 2, further improving workability.

The present invention is not limited to the above-described embodiment. The cross-sectional shape and material of the vertical frame and vertical frame reinforcement material can be changed as appropriate. The specific shape and material of the resin part can be changed as appropriate. The resin part may be attached after the vertical frame reinforcement material is fitted into the front wall of the vertical frame. The fixture of the present invention may not have a screen door, and the vertical frame reinforcement material may be attached to attach a grille.
