Description

This disclosure relates to building materials.

Conventionally, sliding windows (fittings) are known that have a frame body with a frame, and an outer screen and an inner screen that are placed within the frame body (see, for example, Patent Document 1). In order to improve the strength of the frame body, reinforcing plates are attached to the frame body of the frame body, or the thickness of the frame plate is increased. In the sliding window described in Patent Document 1, an L-shaped reinforcing material is attached to the frame to reinforce the frame that is attached to the main body.

JP 2000-274146 A

When reinforcing materials are attached to the frame, manufacturing costs increase. Therefore, there is a demand for reducing manufacturing costs while ensuring the strength of the frame.

The purpose of this disclosure is to provide fittings that can reduce manufacturing costs while ensuring frame strength.

The present disclosure relates to a fitting comprising a frame body having a frame, a shoji screen arranged within the frame body, and a plate-shaped reinforcing material connected to the frame and reinforcing the frame, the frame having a first frame side plate portion extending in the indoor/outdoor direction, and a second frame side plate portion connected to the first frame side plate portion, intersecting the first frame side plate portion and extending in the viewing direction to the opposite side to the side where the shoji screen is arranged and fixed to the main body, the reinforcing material being formed in a plate shape and having a first reinforcing side plate portion fixed to the first frame side plate portion, a second reinforcing side plate portion fixed to the second frame side plate portion, and a reinforcing side inclined plate portion connecting the first reinforcing side plate portion and the second reinforcing side plate portion and extending at an angle relative to the first reinforcing side plate portion and the second reinforcing side plate portion.

FIG. 2 is a front view of a sliding window according to an embodiment of the present invention as seen from the inside of the room. 2 is a longitudinal sectional view taken along line AA in FIG. 1. FIG. 3 is a partially enlarged view of FIG. 2 . FIG. FIG. 13 is a diagram showing the position where the reinforcing material is arranged in another embodiment.

The embodiments of the present disclosure will be described in detail below with reference to the drawings. A sliding window 1 constituting a fitting of one embodiment will be described. In this specification, the "visible direction" refers to the surface direction of the face materials 35, 45 of the sliding window 1 placed in an opening formed in the wall of a building, and the "visible direction" refers to the thickness direction (i.e., the depth direction) of the face materials 35, 45. The "visible direction" is also the indoor/outdoor direction. The "visible surface" refers to each surface of the sliding window 1 facing the outdoor side and the indoor side, and the "visible surface" refers to the surface of the sliding window 1 extending in the indoor/outdoor direction. In the drawings, the outdoor side of the sliding window 1 is the outdoor side X1, and the indoor side of the sliding window 1 is the indoor side X2.

As shown in Figure 1, a sliding window 1 is made up of a frame 2 that is attached to an opening in the building frame, and two shoji screens, an outer shoji screen 3 that is placed on the outside side X1 and an inner shoji screen 4 that is placed on the inside side X2, that are placed inside the frame 2. The outer shoji screen 3 and the inner shoji screen 4 can slide left and right (horizontally) within the frame 2 in the front direction.

The outer shoji screen 3 is constructed by fitting a panel 35 inside a rectangular frame body 30 made up of an upper frame 31, a lower frame 32, a vertical frame 33 located at the door end, and an outer joining frame 34, which is a vertical frame located at the door end.

The inner shoji screen 4 is constructed by fitting a panel 45 inside a rectangular frame body 40 made up of an upper frame 41, a lower frame 42, a vertical frame 43 located at the door end, and an inner joiner frame 44 located at the door tail.

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

The structure of the upper frame 21 will now be described in more detail. As shown in FIG. 2, the upper frame 21 is fixed to the upper structure 10 that constitutes the upper side of the opening in the building framework. While fixed to the upper structure 10, the upper frame 21 is reinforced by the reinforcing material 5.

The upper frame 21 is provided with an exterior rail 211 (exterior downward-projecting rail) and an interior rail 212 (interior downward-projecting rail). The upper frame 21 has a screen rail 213 on the exterior side X1 of the exterior rail 211.

The exterior rail 211 is formed to protrude downward from the upper frame 21 on the exterior side X1 of the upper frame 21, and guides the upper end of the exterior screen 3. The interior rail 212 is formed to protrude downward from the upper frame 21 on the interior side X2 of the upper frame 21, and guides the upper end of the interior screen 4.

The upper frame 21 has a composite structure in which resin cover materials 215, 216 are attached to the inner surface of the metal frame body 214, which is the frame body main body. This provides excellent insulation and moisture resistance. The metal frame body 214 is divided into an outdoor metal frame body 25 and an indoor metal frame body 26 between the outdoor rail 211 and the indoor rail 212. The outdoor metal frame body 25 and the indoor metal frame body 26 are connected by a resin connecting material 27.

The resin cover material 215 is disposed between the exterior rail 211 and the interior rail 212 of the upper frame 21. The resin cover material 216 is configured to include the interior side X2 portion of the interior rail 212 of the upper frame 21, and is provided from the interior side X2 surface of the interior rail 212 to the inner surface of the metal frame 214. The resin cover material 216 has an angle portion 2161 that protrudes toward the interior side X2 beyond the interior end portion 214a of the metal frame 214. The resin cover materials 215, 216 are provided over the entire length of the upper frame 21 in the direction in which it extends.

The exterior metal frame 25 has an indoor/outdoor extending plate portion 251 (first frame side plate portion) that extends in the indoor/outdoor direction, an upwardly protruding fin 252 (second frame side plate portion), an outdoor rail 211, and a screen rail 213.

The outside X1 part of the resin connecting material 27 is fitted and positioned at the end of the inside X2 side of the indoor/outdoor extending plate portion 251. The upwardly protruding fin 252 is connected to the end of the inside X2 side of the indoor/outdoor extending plate portion 251 and protrudes upward (outside in the view direction). The upwardly protruding fin 252 extends perpendicularly (intersects) with the indoor/outdoor extending plate portion 251 in the view direction to the side opposite to the side where the outer screen 3 and inner screen 4 are arranged, and is fixed to the frame 11. The outside rail 211 and the screen rail 213 protrude downward from the underside of the indoor/outdoor extending plate portion 251.

The indoor metal frame 26 has an indoor metal frame main body 261 extending in the indoor/outdoor direction, and an indoor rail 212. The indoor side X2 portion of the resin connecting material 27 is fitted and positioned at the outdoor side X1 end of the indoor metal frame main body 261 extending in the indoor/outdoor direction.

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

The upwardly protruding fins 252 of the upper frame 21 and the first reinforcing side plate portion 51 (described later) of the reinforcing material 5 are fastened together and fixed with screws 521 to the outdoor side X1 surface 11a of the body 11 of the upper structure 10. The indoor/outdoor direction extending plate portion 251 of the upper frame 21 is disposed below the outdoor exterior material 13 and the spacer 12, and a sealing material 13a is provided between the lower end of the outdoor exterior material 13 and the indoor/outdoor direction extending plate portion 251.

A reinforcing member 5 is attached to the upper frame 21. As shown in FIG. 1, the reinforcing member 5 is positioned in the longitudinal center of the upper frame 21, at a position corresponding to the joint 50 between the outer screen 3 and the inner screen 4 in the upper frame 21. As shown in FIG. 3 and FIG. 4, the reinforcing member 5 is positioned across the indoor/outdoor extending plate portion 251 and the upwardly protruding fin 252 of the outdoor metal frame 25.

As shown in Figs. 3 and 4, the reinforcing material 5 is formed in a plate shape, and the cross-sectional shape is formed to have an inclined portion at the corner. The reinforcing material 5 is formed, for example, from a metal material. The reinforcing material 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 formed continuously in this order from the outside side X1 toward the inside side X2.

As shown in FIG. 3, the first reinforcing side plate 51 is formed in a plate shape that has a thickness in the up-down direction and extends in the indoor-outdoor direction. The first reinforcing side plate 51 is disposed along the upper surface of the indoor-outdoor extending plate 251 of the upper frame 21, and is fixed to the indoor-outdoor extending plate 251 by fastening members 511 such as screws.

The second reinforcing side plate 52 has a thickness in the indoor/outdoor direction (projection direction) and is formed in a plate shape extending in the vertical direction. The second reinforcing side plate 52 is fastened together with the upwardly protruding fin 252 of the upper frame 21 to the surface 11a of the outdoor side X1 of the body 11 by fastening members 521 such as screws.

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 at an incline relative to the first reinforcing side plate portion 51 and the second reinforcing side plate portion 52. In this embodiment, the reinforcing side inclined plate portion 53 inclines from the lower side toward the upper side (the outer side in the viewing direction, the side away from the outer screen 3 and the inner screen 4) as it moves from the outside side X1 toward the inside side X2.

The end of the reinforcing side inclined plate portion 53 on the outside X1 side is bent at the bending portion 501 (connection portion) and is connected to the end of the first reinforcing side plate portion 51 on the inside X2 side. The bending portion 501 between the reinforcing side inclined plate portion 53 and the first reinforcing side plate portion 51 is positioned in the indoor/outdoor direction between the position where the upwardly protruding fin 252 of the upper frame 21 is formed and the position where the outside rail 211 of the upper frame 21 is formed.

In this embodiment, the position of the bent portion 501 in the indoor/outdoor direction is, for example, between the position where the upwardly protruding fin 252 of the upper frame 21 is formed and the position where the outdoor rail 211 of the upper frame 21 is formed, and is positioned slightly on the indoor side X2 from the position where the outdoor rail 211 of the upper frame 21 is formed. As a result, the outdoor exterior material 13 can be formed on the outdoor side X1 from the bent portion 510, and the part of the reinforcing material 5 from the bent portion 501 to the reinforcing side inclined plate portion 53 can be positioned on the inner side of the outdoor exterior material 13. Therefore, by forming the outdoor exterior material 13 on the outdoor side X1 from the bent portion 510, the reinforcing side inclined plate portion 53 of the reinforcing material 5 is not visible from the outdoor side X1, and deterioration of the design can be suppressed.

The angle between 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 below, the reinforcing material 5 can bend to a smaller extent at the bending portion 501 than when the first angle θ1 is 90°.

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

The angle between 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 below, the degree to which the reinforcing material 5 bends at the bending portion 502 can be reduced compared to when the second angle θ2 is 90°.

The reinforcing material 5 configured as described above has the reinforcing side inclined plate portion 53, and therefore the first angle θ1 between the reinforcing side inclined plate portion 53 and the first reinforcing side plate portion 51 and the second angle θ2 between the reinforcing side inclined plate portion 53 and the second reinforcing side plate portion 52 are both obtuse angles. Therefore, when a force acts on the upper frame 21 from below, the reinforcing material 5 of the present disclosure is less likely to bend upward than an L-shaped reinforcing material with a 90° corner at the bending portion.

By forming the reinforcing side inclined plate portion 53 on the reinforcing material 5, the reinforcing material 5 of the present disclosure can have a higher strength when a force is applied to the upper frame 21 from below than an L-shaped reinforcing material with a 90° corner of the bent portion. Therefore, by forming the reinforcing side inclined plate portion 53 on the reinforcing material 5, even if the longitudinal length of the upper frame 21 is made shorter than the length of an L-shaped reinforcing material with a 90° corner of the bent portion, the same strength as an L-shaped reinforcing material with a 90° corner of the bent portion can be ensured. Therefore, the reinforcing material 5 provided with the reinforcing side inclined plate portion 53 can be formed to have a shorter longitudinal length of the upper frame 21 than an L-shaped reinforcing material with a 90° corner of the bent portion.

According to this embodiment, the following effects are achieved. The sliding window 1 of this embodiment comprises a frame body 2 having an upper frame 21, an outer screen 3 and an inner screen 4 arranged within the frame body 2, and a plate-shaped reinforcing material 5 connected to the upper frame 21 and reinforcing the upper frame 21. The upper frame 21 has a first frame side plate portion 251 extending in the indoor/outdoor direction, and a first frame side plate portion 251 connected to the first frame side plate portion 251 and intersecting the first frame side plate portion 251 to extend in the viewing direction opposite the side on which the outer screen 3 and inner screen 4 are arranged. and a second frame side plate portion 252 fixed to the main body 11, and 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 side inclined plate portion 53 that connects the first reinforcing side plate portion 51 and the second reinforcing side plate portion 52 and extends at an angle relative to the first reinforcing side plate portion 51 and the second reinforcing side plate portion 52.

By forming the reinforcing side inclined plate portion 53 on the reinforcing material 5, the longitudinal length of the upper frame 21 can be made shorter and more compact than an L-shaped reinforcing material with a 90° corner at the bent portion, while still ensuring the strength to reinforce the upper frame 21. Therefore, by forming the reinforcing material 5 compactly, less material is used, and the manufacturing equipment can be made compact, reducing manufacturing costs while still ensuring the strength to reinforce the upper frame 21 with the reinforcing material 5.

In this embodiment, the bent portion 501 between the first reinforcing side plate portion 51 and the reinforcing side inclined plate portion 53 is positioned in the indoor/outdoor direction between the position where the second frame side plate portion 252 of the upper frame 21 is formed and the position where the outdoor rail 211 is formed. As a result, when the outdoor exterior material 13 is provided on the outdoor side X1 of the body 11, the portion from the bent portion 501 of the reinforcing material 5 to the reinforcing side inclined plate portion 53 can be positioned on the inside side of the outdoor exterior material 13 in the indoor/outdoor direction, so that the reinforcing side inclined plate portion 53 of the reinforcing material 5 is not visible from the outdoor side X1, and deterioration of the design can be suppressed.

In this embodiment, the reinforcing material 5 is disposed in the longitudinal center of the upper frame 21. This allows the force acting on the upper frame 21 to be received in a state where it is reinforced by the reinforcing material 5 in the longitudinal center of the upper frame 21. Therefore, the upper frame 21 can be stably reinforced by the reinforcing material 5 in the longitudinal center of the upper frame 21.

In this embodiment, the reinforcing material 5 is disposed at a position on the upper frame 21 corresponding to the joint 50 between the outer screen 3 and the inner screen 4. At the joint 50 between the outer screen 3 and the inner screen 4, when the outer screen 3 and the inner screen 4 are closed, the outer joint frame 34 of the outer screen 3 and the inner joint frame 44 of the inner screen 4 are disposed overlapping in the indoor/outdoor direction. Therefore, at the joint 50 between the outer screen 3 and the inner screen 4, force is likely to act on the upper frame 21. In such a case, by disposing the reinforcing material 5 at a position on the upper frame 21 corresponding to the joint 50 between the outer screen 3 and the inner screen 4, the upper frame 21 can be effectively reinforced by the reinforcing material 5 at the position on the upper frame 21 where force is likely to act.

Although a preferred embodiment of the present disclosure has been described above, the present disclosure is not limited to the above-described embodiment and can be modified as appropriate.

In the above embodiment, the reinforcing member 5 is provided at a position corresponding to the joint 50 between the outer screen 3 and the inner screen 4 in the upper frame 21, but this is not limited to this. For example, as in another embodiment shown in Figure 5, the reinforcing member 5A may be provided at a position corresponding to the joint 50 in the longitudinal center of the lower frame 22, or the reinforcing member 5B may be provided in the longitudinal center of one or both of the vertical frames 23, 24.

In the above embodiment, as shown in FIG. 1, one reinforcing member 5 is provided in the longitudinal center of the upper frame 21, or one reinforcing member 5B is provided in the longitudinal center of the lower frame 22 and the vertical frames 23 and 24, as shown in FIG. 5, but this is not limited to the above. Multiple reinforcing members may be provided along the longitudinal direction of the frame (upper frame, lower frame, vertical frame).
