Joinery such as sashes as described above has wind pressure resistance according to the environment of the area where they are installed. Therefore, if the rail is used in an area where the wind pressure exceeds the assumption is applied to the fitting, the rail of the lower frame may be deformed due to the bending of the shoji caused by the wind pressure. If the rail of the lower frame is deformed, it may interfere with the opening and closing of the shoji. Therefore, it is conceivable to increase the wall thickness of the frame provided with the rail to increase the strength. However, if the wall thickness of the frame is increased, existing parts cannot be attached, the number of types of profile increases, the control of profile increases, and a new processing die is required, which may increase the cost.

The present invention has been made in view of such a problem, and an object of the present invention is to provide a fitting having higher wind pressure resistance while suppressing the cost.

In order to achieve such an object, the fitting of the present invention comprises a plurality of sashes, a horizontal frame having a plurality of rails supporting the plurality of sashes, and two of the plurality of rails adjacent to each other. It is a fitting characterized by having a regulating member provided between the rails and restricting deformation of the two rails to the opposite sides to each other.

According to such fittings, since a regulating member for restricting the deformation of the two rails to the opposite sides is provided between the two rails adjacent to each other, the two rails are supported by the two rails. Even when wind pressure acts on each shoji to cause bending, the deformation of one of the rails is regulated by the other rail via the regulating member, so that the deformation of the rail is suppressed. At this time, since the regulating member is a member provided between the two rails, it is cheaper than, for example, when the types of horizontal frames are increased by increasing the wall thickness of the entire frame body. Therefore, it is possible to provide fittings having higher wind pressure resistance while suppressing costs.

The fitting is characterized in that the regulating member is provided between the mating portion of the two shoji screens supported by the two rails and the horizontal frame.
According to such fittings, since the regulating member is provided between the mating portion and the horizontal frame, which are most flexible in each shoji, the rail is efficiently suppressed by suppressing the deformation of the rail at the mating portion. It is possible to suppress the deformation of.

In such a fitting, the sash has a sliding member that slides with the rail when moving, and the restricting member is the sash that the two sashes each supported by the two rails have. It is characterized in that it is provided between the sliding member and the horizontal frame.
According to such fittings, the regulating member is provided between the sliding member that comes into contact with the rail when each shoji is bent and the horizontal frame, so that the deformation of the portion where the external force acts is regulated. Therefore, it is possible to suppress the deformation of the rail more efficiently.

The two fittings, each supported by the two rails, are characterized by having an engaging portion that engages with each other and restricts movement in a direction away from each other in a prospective direction. do.
According to such fittings, the two sashes supported by the two rails are restricted from moving in the direction in which the engaging portions are engaged and separated from each other, so that one of the two sashes is used. By regulating the bending of the two shoji by the other shoji, the bending of the two shoji is suppressed. Therefore, it is possible to reduce the force acting on the rail and further suppress the deformation of the rail.

In such a fitting, a wind blocking member that prevents air flow and has flexibility is provided between the two shoji screens supported by the two rails and the horizontal frame. The regulating member is characterized in that it is made of a material that is harder than the windbreak member.
According to such fittings, a wind blocking member and a regulating member made of a material harder than the wind blocking member are provided between the two shoji and the horizontal frame, so that the flexibility is improved. It is possible to prevent the flow of air by the wind blocking member, and to have a high wind pressure resistance by the regulating member which is harder than the wind blocking member.

It has a windbreak member 8 and a regulation member 9 arranged between them.

The inner cover member 44 is provided by being locked to an inner protrusion 42c provided on the interior wall portion 42a and an inner hook portion 42d provided on the lower frame upper surface portion 42b. The inner protrusion 42c is an outdoor surface of the indoor wall portion 42a and is provided so as to project outward slightly above the lower frame upper surface portion 42b, and the inner hook portion 42d is provided with the indoor wall portion 42a and the inner surface.

The step portion 42f has an intermediate wall between an indoor upper surface portion 42h connected to the inner rail 4a on the indoor side and an outdoor upper surface portion 42i connected to the outer rail 4b on the outdoor side and forming a lower surface than the indoor upper surface portion 42h. It is formed by being connected vertically by a portion 42j. In the stepped protrusion 42g, the indoor upper surface portion 42h protrudes to the outdoor side from the intermediate wall portion 42j, so that the indoor upper surface portion 42g protrudes above the outdoor surface portion 42g.

The windbreak member 8 is formed of a flexible and soft synthetic resin, and is provided on the base portion 8a and the base portion 8a to be fitted between the inner rail 4a and the outer rail 4b, and is expected to be provided. It has a plurality of fin-shaped portions 8b rising along the direction. The tip of the fin-shaped portion 8b is in contact with the lower ends of the combination stiles 24 and 34 of the internal sash 2 and the external sash 3 with the tip closed, and between the internal sash 2 and the external sash 3 under the combination stile 24 and 34. It prevents the flow of air.

The regulating member 9 is a block-shaped member formed of a synthetic resin material harder than the windbreak member 8 and whose upper surface 9a forms a substantially horizontal plane, and the upper surface 9a is a closed internal sash 2 and an external sash 3. It is configured so that it does not come into contact with the lower ends of the stiles 24 and 34 at intervals. Further, the upper surface 9a of the regulating member 9 is located at a position higher than the upper surface portion 42b of the lower frame. The regulating member 9 is provided side by side with the wind blocking member 8 in the left-right direction, and is arranged between the wind blocking member 8 and the outer cover member 45. Is locked in.

As shown in FIG. 6, the regulating member 9 is arranged on the indoor upper surface portion 42h according to the shape of the lower frame upper surface portion 42b between the inner rail 4a and the outer rail 4b, and is thinner than the outdoor side portion. The indoor thin-walled portion 9b and the outdoor thick-walled portion 9c arranged on the outdoor upper surface portion 42i and thicker than the indoor thin-walled portion 9b are integrally formed. An outdoor groove portion 9e is provided along the longitudinal direction at a position slightly higher than the lower surface 9d at the lower portion of the outdoor surface of the outdoor thick portion 9c. Further, a lower protrusion 9f protruding toward the indoor side is provided at the lower part of the indoor side surface of the outdoor thick portion 9c.

To attach the regulating member 9 to the lower frame 42, first, the regulating member 9 is tilted so that the outdoor thick portion 9c side is lower than the indoor thin portion 9b side, and the inner rail 4a of the lower frame 42 is attached. Insert it between the outer rail 4b. At this time, the regulating member 9 is inserted between the inner rail 4a and the outer rail 4b so that the outer protrusion 42e of the lower frame 42 enters the outdoor groove portion 9e of the regulating member 9.

Next, the regulating member 9 is tilted with the lower edge of the outdoor side of the outdoor thick portion 9c close to the outdoor upper surface portion 42i and the upper edge of the outdoor side of the outdoor thick portion 9c close to the outer rail 4b. The regulation member 9 is rotated so that the indoor thin portion 9b side of the room is lowered. Due to the rotation of the regulating member 9, the outer protrusion 42e of the lower frame 42 engages with the outdoor groove portion 9e of the regulating member 9, and the stepped protrusion 42g of the lower frame 42 engages with the lower protrusion 9f of the regulating member 9 to engage with the regulating member. 9 is locked to the lower frame 42. The locked regulation member 9 is arranged with almost no gap between the inner rail 4a and the outer rail 4b.

In this way, the regulation member 9 is rotated and attached, and the regulation member 9 can be arranged with almost no gap between the inner rail 4a and the outer rail 4b. An inclined portion 9g is provided so that the thickness becomes thinner toward the outdoor side, and an inclined portion 9i is provided on the indoor side portion of the lower surface 9h of the indoor thin wall portion 9b so that the thickness becomes thinner toward the indoor side. Has been done. Further, the upper surface of the stepped protrusion 42g of the lower frame 42 is inclined so that the height of the stepped protrusion 42g and the lower protrusion 9f are lowered toward the outdoor side so that the lower protrusion 9f can be easily engaged. , It has a high slope toward the indoor side.

When a positive pressure or a negative pressure due to wind pressure acts on the inner sash 2 and the outer sash 3, the fitting 1 may bend so that the central portion in the vertical direction swells indoors or outdoors. The bending generated at this time is the upper stiles 21, 31, lower stiles 22, 32, door tip stiles 23, which are engaged with the upper frame 41, the lower frame 42, and the vertical frame 43 of the frame body 4 along the longitudinal direction. It occurs larger in the merging portion 1a where the merging stiles 24 and 34 are located than in 33. Therefore, when positive pressure or negative pressure is applied, the sliding members 2b and 3b provided at the lower ends of the combination rails 24 and 34, which cause larger bending, are caused by the bending of the shoji 2 and 3. The inner rail 4a and the outer rail 4b are pressed in the prospective direction.

At this time, when the regulating member 9 such as the fitting 1 of the present embodiment is not provided, the inner rail 4a and the outer rail 4b pressed by the sliding members 2b and 3b are the upper surfaces of the lower frame which are the base ends. It is deformed by a bending moment centered on the boundary portion with the portion 42b. On the other hand, since the fitting 1 of the present embodiment is provided with the regulating member 9 between the inner rail 4a and the outer rail 4b, for example, the shoji 2 and 3 are warped so as to bulge outward due to negative pressure. In this case, since the inner rail 4a pressed to the outdoor side is restricted from being deformed to the outdoor side by the regulating member 9, the bending moment acts on the portion above the upper surface 9a of the regulating member 9. Therefore, since the bending moment acting on the inner rail 4a is smaller than that in the case where the regulating member 9 is not provided, the deformation of the inner rail 4a and the amount of displacement of the bent inner shoji 2 to the outdoor side are small. It can be suppressed.

Further, at this time, the internal sash 2 and the external sash 3 are restricted from moving in the direction in which the internal sash extension piece 24a and the external sash extension piece 34a are engaged with each other and are separated from each other. The amount of displacement toward the indoor side is suppressed to a small size, and the deformation of the outer rail 4b is also suppressed.

Further, when the shoji 2 and 3 warp so as to bulge inward due to positive pressure, the outer rail 4b pressed to the indoor side is restricted from being deformed to the indoor side by the regulating member 9. , The bending moment acts on the portion above the upper surface 9a of the regulating member 9. Therefore, since the bending moment acting on the outer rail 4b is smaller than that in the case where the regulating member 9 is not provided, the amount of deformation and bending of the outer rail 4b to the indoor side is small. It can be suppressed.

Further, at this time, the internal sash 2 and the external sash 3 are restricted from moving in the direction in which the internal sash extension piece 24a and the external sash extension piece 34a are engaged with each other and are separated from each other. The amount of displacement to the outdoor side is suppressed to a small size, and the deformation of the inner rail 4a is also suppressed.

As described above, according to the fitting of the present embodiment, the regulating member 9 for restricting the deformation of the inner rail 4a and the outer rail 4b to the opposite sides is provided between the inner rail 4a and the outer rail 4b. Therefore, even if wind pressure acts on each of the obstacles 2 and 3 supported and guided by the inner rail 4a and the outer rail 4b to cause bending, deformation of one of the rails 4a and 4b Is regulated by the other rails 4a and 4b via the regulating member 9, so that deformation of the inner rail 4a and the outer rail 4b is suppressed. At this time, since the regulating member 9 is a member provided between the inner rail 4a and the outer rail 4b, the types of the frame body 4 and the molding die increase by increasing the wall thickness of the entire frame body 4. It is cheaper than the case. Therefore, it is possible to provide the fitting 1 having higher wind pressure resistance while suppressing the cost.

Further, since the regulating member 9 is provided under the mating portion 1a that is most flexible in each of the shoji screens 2 and 3 and between the mating portion 42 and the lower frame 42, the inner rail 4a and the outer rail are provided at the mating portion 1a. By suppressing the deformation of 4b, it is possible to efficiently suppress the deformation of the inner rail 4a and the outer rail 4b.

Further, the regulating member 9 is provided under the sliding members 2b and 3b that come into contact with the inner rail 4a and the outer rail 4b when the obstacles 2 and 3 are bent, and is provided between the lower frame 42. Therefore, it is possible to regulate the deformation of the portion where the sliding members 2b and 3b are in contact with each other and to act on the external force, and to more efficiently suppress the deformation of the inner rail 4a and the outer rail 4b.

Further, since the internal sash 2 and the external sash 3 are restricted from moving in the direction in which the internal sash extension piece 24a and the external sash extension piece 34a are engaged with each other and separated from each other, the internal sash 2 and the external sash 3 are restricted. By regulating the bending of one of the shoji screens 2 and 3 by the other shoji screen 2 and 3, the relative displacement of the two shoji screens 2 and 3 with respect to the skeleton is suppressed. Therefore, it is possible to reduce the force acting on the inner rail 4a and the outer rail 4b and suppress the deformation of the inner rail 4a and the outer rail 4b.

Further, since the wind blocking member 8 and the regulating member 9 made of a material harder than the wind blocking member 8 are provided under the inner sash 2 and the outer sash 3, the wind has flexibility. It is possible to prevent the flow of air by the stop member 8 and to have a high wind pressure resistance by the regulation member 9 which is harder than the wind stop member 8.

In the above embodiment, a fitting having two shoji screens, an internal shoji screen and an external shoji screen, has been described as an example, but the present invention is not limited to this, and a fitting having three or more shoji screens may be used. Further, in the above embodiment, the fitting 1 for the sliding window has been described as an example, but the present invention is not limited to this. For example, one of the two shoji screens supported by two adjacent rails may be fixed so as not to be slidable, and the other may be a fitting for a so-called single sliding window that is slidable. Therefore, as long as the rail itself has a form in which the shoji is supported and can be slidably moved, the rail may be supported by the rail so that the shoji cannot be slidably moved.

In the above embodiment, an example in which the regulating member 9 is provided between the inner rail 4a and the outer rail 4b has been described, but the present invention is not limited to this, and for example, between the outer rail 4b and the screen door rail 4c, or. When a plurality of rails are provided, they may be provided between two adjacent rails.

In the above embodiment, the regulating member 9 is a block-shaped member made of synthetic resin, but the present invention is not limited to this. For example, the upper surface may be curved rather than horizontal, may be dented downward, or may have a convex shape on the upper side. Further, the cross section is U-shaped or H, which has high rigidity and has a pair of wall portions facing each other and arranged along the rail and a connecting portion connecting the upper end or the vertical intermediate portion of the pair of wall portions. Even if it is a member having a shape such as a character shape, it may be a member that is fitted between two adjacent rails and regulates deformation of the two rails to the side facing each other. Further, in the above embodiment, the lower frame is used, but the present invention is not limited to this, and the upper frame may be used.

Further, the above-described embodiment is for facilitating the understanding of the present invention, and is not for limiting the interpretation of the present invention. It goes without saying that the present invention can be modified and improved without departing from the spirit thereof, and the present invention includes an equivalent thereof.
