Embodiments for Carrying Out the Invention

[0008] Hereinafter, embodiments of the present disclosure will be described in detail with reference to the drawings. The sliding window 1 constituting the fitting according to one embodiment will be described. In this specification, the "looking direction" means the surface direction of the facing materials 35 and 45 in the sliding window 1 housed in the opening formed in the wall of the building, and the "depth direction" means the thickness direction (i.e., the depth direction) of the facing materials 35 and 45. The "depth direction" is also the indoor-outdoor direction. The "looking surface" means each surface facing the outdoor side and the indoor side in the sliding window 1, and the "depth surface" means a surface extending in the indoor-outdoor direction in the sliding window 1. In the drawings, the outdoor side of the sliding window 1 is referred to as the outdoor side X1, and the indoor side of the sliding window 1 is referred to as the indoor side X2.

[0009] As shown in FIG. 1, the offset window 1 is configured by accommodating two shutters, namely a frame body 2 attached to an opening of a building body, an outer shutter 3 disposed on the outdoor side X1 inside the frame body 2, and an inner shutter 4 disposed on the indoor side X2. The outer shutter 3 and the inner shutter 4 are slidable in the left-right direction (lateral direction) of the viewing direction within the frame body 2.

[0010] The outer shutter 3 is configured by accommodating a facing material 35 inside a frame body 30 formed by rectangularly framing an upper frame 31, a lower frame 32, a vertical frame 33 disposed on the door tip side, and an outer call-together frame 34 which is a vertical frame disposed on the door butt side.

[0011] The inner shutter 4 is configured by accommodating a facing material 45 inside a frame body 40 formed by rectangularly framing an upper frame 41, a lower frame 42, a vertical frame 43 disposed on the door tip side, and an inner call-together frame 44 which is a vertical frame disposed on the door butt side.

[0012] The frame body 2 is configured by rectangularly framing an upper frame 21, a lower frame 22, and a pair of left and right vertical frames 23, 24.

[0013] The configuration of the upper frame 21 will be further described in detail. As shown in FIG. 2, the upper frame 21 is fixed to an upper structure body 10 that constitutes the upper part of the opening of the building body. The upper frame 21 is reinforced by a reinforcing material 5 in a state of being fixed to the upper structure body 10.

[0014] The upper frame 21 is provided with an outdoor rail 211 (outdoor lower protruding rail) and an indoor rail 212 (indoor lower protruding rail). The upper frame 21 has a screen door rail 213 on the outdoor side X1 of the outdoor rail 211.

[0015] The outdoor rail 211 is formed to protrude downward from the upper frame 21 on the outdoor side X1 of the upper frame 21 and guides the upper end portion of the outer shutter 3. The indoor rail 212 is formed to protrude downward from the upper frame 21 on the indoor side X2 of the upper frame 21 and guides the upper end portion of the inner shutter 4.

[0016] The upper frame 21 has a composite structure in which resin cover materials 215 and 216 are attached to the inner surface of a metal frame body 214 that is the frame body itself. Therefore, it has excellent heat insulation and dew prevention properties. The metal frame body 214 is divided into an outdoor metal frame body 25 and an indoor metal frame body 26 between an outdoor rail 211 and an indoor rail 212. The outdoor metal frame body 25 and the indoor metal frame body 26 are connected by a resin connecting material 27.

[0017] The resin cover material 215 is disposed between the outdoor rail 211 and the indoor rail 212 in the upper frame 21. The resin cover material 216 is configured to include a portion of the indoor side X2 of the indoor rail 212 in the upper frame 21, and is provided from the surface of the indoor side X2 of the indoor rail 212 to the inner surface of the metal frame body 214. The resin cover material 216 has an angle portion 2161 that protrudes indoor side X2 from the indoor side end portion 214a of the metal frame body 214. The resin cover materials 215 and 216 are provided over the entire length of the upper frame 21 in the extending direction.

[0018] The outdoor metal frame body 25 has an indoor-outdoor direction extending plate portion 251 (first frame side plate portion) extending in the indoor-outdoor direction, an upward protruding fin 252 (second frame side plate portion), an outdoor rail 211, and a screen door rail 213.

[0019] At the indoor side X2 end of the indoor-outdoor direction extending plate portion 251, the outdoor side X1 portion of the resin connecting material 27 is fitted and disposed. The upward protruding fin 252 is connected to the indoor side X2 end of the indoor-outdoor direction extending plate portion 251 and protrudes upward (to the outer side in the finding direction). The upward protruding fin 252 extends orthogonally (intersects) with the indoor-outdoor direction extending plate portion 251 and extends to the side opposite to the side where the outer shutter 3 and the inner shutter 4 are disposed in the finding direction, and is fixed to the building body 11. The outdoor rail 211 and the screen door rail 213 protrude downward from the lower surface of the indoor-outdoor direction extending plate portion 251.

[0020] The indoor metal frame body 26 has an indoor side metal frame body main body 261 extending in the indoor-outdoor direction and an indoor rail 212. At the outdoor side X1 end of the indoor side metal frame body main body 261 extending in the indoor-outdoor direction, the indoor side X2 portion of the resin connecting material 27 is fitted and disposed.

[0021] The upper frame 21 is fixed to the upper structure 10. The upper structure 10 includes a body 11, an outdoor exterior material 13 disposed on the outdoor side X1 of the body 11 via a spacer 12, an indoor interior material 15 disposed on the indoor side X2 of the body 11 via a spacer 14, and an upper frame member 17 disposed on the lower side of the body 11 via a spacer 16. The body 11 includes a structural wall 111 and a beam member 112 disposed at the lower part of the structural wall 111. In the present embodiment, for example, in the indoor-outdoor direction, the position of the surface 131 on the outdoor side X1 of the outdoor exterior material 13 is the same as the position of the surface 211a on the outdoor side X1 of the outdoor rail 211 of the upper frame 21.

[0022] On the surface 11a on the outdoor side X1 of the body 11 of the upper structure 10, the upward protruding fin 252 of the upper frame 21 and the first reinforcing side plate portion 51 (described later) of the reinforcing member 5 are fastened and fixed together by screws 521. Below the outdoor exterior material 13 and the spacer 12, an indoor-outdoor direction extending plate portion 251 of the upper frame 21 is disposed, and a sealing material 13a is provided between the lower end portion of the outdoor exterior material 13 and the indoor-outdoor direction extending plate portion 251.

[0023] The reinforcing member 5 is attached to the upper frame 21. As shown in FIG. 1, the reinforcing member 5 is disposed at a position corresponding to the mating portion 50 between the outer shutter 3 and the inner shutter 4 in the upper frame 21 at the central portion in the longitudinal direction of the upper frame 21. As shown in FIGS. 3 and 4, the reinforcing member 5 is disposed across the indoor-outdoor direction extending plate portion 251 and the upward protruding fin 252 of the outdoor metal frame body 25.

[0024] The reinforcing member 5 is formed in a plate shape as shown in FIGS. 3 and 4, and the cross-sectional shape is formed into a shape having an inclined portion at the corner. The reinforcing member 5 is formed of, for example, a metal material. The reinforcing member 5 has a first reinforcing side plate portion 51, a second reinforcing side plate portion 52, and a reinforcing side inclined plate portion 53. The first reinforcing side plate portion 51, the reinforcing side inclined plate portion 53, and the second reinforcing side plate portion 52 are continuously formed in this order from the outdoor side X1 toward the indoor side X2.

[0025] As shown in FIG. 3, the first reinforcing side plate portion 51 has a thickness in the vertical direction and is formed in a plate shape extending in the indoor-outdoor direction. The first reinforcing side plate portion 51 is disposed along the upper surface of the indoor-outdoor direction extending plate portion 251 of the upper frame 21 and is fixed to the indoor-outdoor direction extending plate portion 251 by a fastening member 511 such as a screw.

[0026] The second reinforcing side plate portion 52 has a thickness in the indoor-outdoor direction (expected direction) and is formed in a plate shape extending in the vertical direction. The second reinforcing side plate portion 52 is fastened and fixed together with the upward protruding fin 252 of the upper frame 21 to the surface 11a of the outdoor side X1 of the housing 11 by a fastening member 521 such as a screw.

[0027] The reinforcing side inclined plate portion 53 connects the first reinforcing side plate portion 51 and the second reinforcing side plate portion 52. The reinforcing side inclined plate portion 53 extends inclined with respect to the first reinforcing side plate portion 51 and the second reinforcing side plate portion 52. In the present embodiment, the reinforcing side inclined plate portion 53 inclines so as to go from the lower side to the upper side (the outer side in the finding direction, the side away from the outer shutter 3 and the inner shutter 4) as it goes from the outdoor side X1 to the indoor side X2.

[0028] The outdoor side X1 end portion of the reinforcing side inclined plate portion 53 is a portion bent at the bent portion 501 (connection portion) and is connected to the indoor side X2 end portion of the first reinforcing side plate portion 51. The bent portion 501 of the reinforcing side inclined plate portion 53 and the first reinforcing side plate portion 51 is disposed between the position where the upward protruding fin 252 of the upper frame 21 is formed and the position where the outdoor side rail 211 of the upper frame 21 is formed in the indoor-outdoor direction position.

[0029] In this embodiment, the position of the bending portion 501 in the indoor-outdoor direction is, for example, between the position where the upward protruding fin 252 of the upper frame 21 is formed and the position where the outdoor side rail 211 of the upper frame 21 is formed, and is arranged slightly closer to the indoor side X2 than the position where the outdoor side rail 211 of the upper frame 21 is formed. Thereby, the outdoor side exterior material 13 is formed on the outdoor side X1 rather than the bending portion 510, and the portion from the bending portion 501 of the reinforcing member 5 to the reinforcing side inclined plate portion 53 can be arranged on the inner side of the outdoor side exterior material 13. Therefore, by forming the outdoor side exterior material 13 on the outdoor side X1 rather than the bending portion 510, the reinforcing side inclined plate portion 53 of the reinforcing member 5 is not visible from the outdoor side X1, so that a decrease in design quality can be suppressed.

[0030] The angle formed by the reinforcing side inclined plate portion 53 and the first reinforcing side plate portion 51 is the first angle θ1. The first angle θ1 is an obtuse angle. By forming the first angle θ1 as an obtuse angle (90° < θ1 < 180°), when a force acts on the upper frame 21 from the lower side, the reinforcing member 5 can reduce the degree of bending at the bending portion 501 compared to the case where the first angle θ1 is 90°.

[0031] The end portion of the reinforcing side inclined plate portion 53 on the indoor side X2 is a portion bent at the bending portion 502 and is connected to the lower end portion of the second reinforcing side plate portion 52. The bending portion 502 of the reinforcing side inclined plate portion 53 and the second reinforcing side plate portion 52 is arranged between the position where the outdoor side rail 211 is arranged and the position where the indoor side rail 212 is arranged in the indoor-outdoor direction.

[0032] The angle formed by the reinforcing side inclined plate portion 53 and the second reinforcing side plate portion 52 is the second angle θ2. The second angle θ2 is an obtuse angle. By forming the second angle θ2 as an obtuse angle (90° < θ1 < 180°), when a force acts on the upper frame 21 from the lower side, the reinforcing member 5 can reduce the degree of bending at the bending portion 502 compared to the case where the second angle θ2 is 90°.

[0033] The reinforcing member 5 configured as described above has a reinforcing inclined plate portion 53. As a result, both the first angle θ1 formed by the reinforcing inclined plate portion 53 and the first reinforcing side plate portion 51 and the second angle θ2 formed by the reinforcing inclined plate portion 53 and the second reinforcing side plate portion 52 are obtuse angles. Therefore, when a force acts on the upper frame 21 from the lower side, the corner portion of the bent portion of the reinforcing member 5 of the present disclosure is less likely to bend upward than an L-shaped reinforcing member with a 90° corner at the bent portion.

[0034] Thus, by forming the reinforcing inclined plate portion 53 in the reinforcing member 5, the reinforcing member 5 of the present disclosure can increase the strength when a force acts on the upper frame 21 from the lower side compared to an L-shaped reinforcing member with a 90° corner at the bent portion. Therefore, by forming the reinforcing inclined plate portion 53 in the reinforcing member 5, even if the length of the upper frame 21 in the longitudinal direction is shorter than the length of an L-shaped reinforcing member with a 90° corner at the bent portion, the same strength as that of an L-shaped reinforcing member with a 90° corner at the bent portion can be ensured. Accordingly, the reinforcing member 5 provided with the reinforcing inclined plate portion 53 can be formed with a shorter length in the longitudinal direction of the upper frame 21 than an L-shaped reinforcing member with a 90° corner at the bent portion.

[0035] According to the present embodiment, the following effects are achieved. The sliding window 1 of the present embodiment includes a frame body 2 having an upper frame 21, an outer shutter 3 and an inner shutter 4 disposed within the frame body 2, and a plate-shaped reinforcing member 5 connected to the upper frame 21 to reinforce the upper frame 21. The upper frame 21 has a first frame side plate portion 251 extending in the indoor-outdoor direction, and a second frame side plate portion 252 connected to the first frame side plate portion 251 and extending in a direction opposite to the side where the outer shutter 3 and the inner shutter 4 are disposed in the viewing direction and intersecting the first frame side plate portion 251 and fixed to the building body 11. The reinforcing member 5 is formed in a plate shape and has a first reinforcing side plate portion 51 fixed to the first frame side plate portion 251, a second reinforcing side plate portion 52 fixed to the second frame side plate portion 252, and a reinforcing inclined plate portion 53 connecting the first reinforcing side plate portion 51 and the second reinforcing side plate portion 52 and extending inclined with respect to the first reinforcing side plate portion 51 and the second reinforcing side plate portion 52.

[0036] This ensures the strength for reinforcing the upper frame 21. By forming the reinforcing side inclined plate portion 53 on the reinforcing member 5, the length of the upper frame 21 in the longitudinal direction can be made shorter and more compact than that of an L-shaped reinforcing member with a 90° corner at the bent portion. Therefore, while ensuring the strength for reinforcing the upper frame 21 with the reinforcing member 5, the reinforcing member 5 can be formed compactly, reducing the amount of material used and making the manufacturing equipment more compact, thereby reducing the manufacturing cost.

[0037] In the present embodiment, the bent portion 501 between the first reinforcing side plate portion 51 and the reinforcing side inclined plate portion 53 is disposed between the position where the second frame side plate portion 252 of the upper frame 21 is formed and the position where the outdoor side rail 211 is formed in the indoor-outdoor direction. Thus, when the outdoor side exterior material 13 is provided on the outdoor side X1 of the housing 11, in the indoor-outdoor direction, the portion from the bent portion 501 of the reinforcing member 5 to the reinforcing side inclined plate portion 53 can be disposed inside the outdoor side exterior material 13. Therefore, the reinforcing side inclined plate portion 53 of the reinforcing member 5 cannot be visually recognized from the outdoor side X1, and a decrease in design quality can be suppressed.

[0038] In the present embodiment, the reinforcing member 5 is disposed at the central portion in the longitudinal direction of the upper frame 21. Thereby, the force acting on the upper frame 21 can be received in a state of being reinforced by the reinforcing member 5 at the central portion in the longitudinal direction of the upper frame 21. Therefore, the reinforcement of the upper frame 21 by the reinforcing member 5 can be stably performed at the central portion in the longitudinal direction of the upper frame 21.

[0039] In the present embodiment, the reinforcing member 5 is disposed at a position corresponding to the mating portion 50 between the outer shutter 3 and the inner shutter 4 in the upper frame 21. At the mating portion 50 between the outer shutter 3 and the inner shutter 4, when the outer shutter 3 and the inner shutter 4 are closed, the outer mating frame 34 of the outer shutter 3 and the inner mating frame 44 of the inner shutter 4 are disposed overlapping in the indoor-outdoor direction. Therefore, at the mating portion 50 between the outer shutter 3 and the inner shutter 4, a force is likely to act on the upper frame 21. In such a case, by disposing the reinforcing member 5 at a position corresponding to the mating portion 50 between the outer shutter 3 and the inner shutter 4 in the upper frame 21, the upper frame 21 can be effectively reinforced by the reinforcing member 5 at the position where the force is likely to act on the upper frame 21.

[0040] As described above, a preferred embodiment of the present disclosure has been explained. However, the present disclosure is not limited to the above-described embodiment and can be appropriately modified.

[0041] In the above embodiment, the reinforcing member 5 is provided at a position corresponding to the mating portion 50 between the outer shutter 3 and the inner shutter 4 in the upper frame 21, but it is not limited thereto. For example, as in another embodiment shown in FIG. 5, the reinforcing member 5A may be provided at a position corresponding to the mating portion 50 at the center in the longitudinal direction of the lower frame 22, or the reinforcing member 5B may be provided at the center in the longitudinal direction of one or both of the pair of vertical frames 23 and 24.

[0042] Also, in the above embodiment, as shown in FIG. 1, one reinforcing member 5 is provided at the center in the longitudinal direction of the upper frame 21, or as shown in FIG. 5, one reinforcing member 5B is provided at the center in the longitudinal direction of the lower frame 22 and the vertical frames 23 and 24, but it is not limited thereto. A plurality of reinforcing members may be provided along the longitudinal direction of the frame (upper frame, lower frame, vertical frame).
