Description

[Technical field]

[0001] The present invention relates to a fitting having a shoji screen molded from resin. [Background technology]

[0002] There are fittings in which the upper frame, lower frame, and left and right vertical frames that make up a shoji screen are each made of resin. This type of fitting has an advantage in terms of heat insulation compared to fittings whose frames are made of metal such as aluminum alloy (for example, see Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2014-167212 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, it cannot be denied that resin-molded frame materials are less rigid than metal-molded frame materials. In particular, it is difficult to ensure high dimensional accuracy in frame materials with large longitudinal dimensions, and there is concern that deformation such as bending and twisting may occur. Furthermore, resin-made frame materials are more susceptible to the effects of heat such as solar radiation than metal-made frame materials, and there is also a risk of thermal deformation. For this reason, there have been conventionally provided frame materials that solve the above-mentioned problems by adding a reinforcing material molded from metal to the resin-made frame material. However, there is a concern that the metal reinforcing material added to the frame material acts as a thermal bridge and impairs the insulating properties of the shoji screen to which it is applied.

[0005] In view of the above-mentioned circumstances, the present invention aims to provide a fitting that can prevent deformation of a shoji screen without compromising its thermal insulation properties. [Means for solving the problem]

[0006] In order to achieve the above-mentioned objective, the fitting of the present invention is a fitting comprising a frame and a shoji screen, the shoji screen being constructed with a frame material molded from resin, the frame material having an exterior facing wall portion facing the outside of the room and an interior facing wall portion facing the inside of the room, and a metal reinforcing material is arranged between the exterior facing wall portion and the interior facing wall portion, and an insulating material is arranged to suppress heat transfer in the forward direction. Effect of the Invention

[0007] According to the present invention, the reinforcing material improves the rigidity and heat resistance of the frame material, preventing deformation of the shoji screen. Moreover, the heat insulation material suppresses heat transfer in the forward direction, so there is no risk of the insulation being impaired. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] A preferred embodiment of the fittings according to the present invention will be described in detail below with reference to the attached drawings. For convenience, the terms "visible direction" and "visible direction" may be used below. The "visible direction" is the direction along the depth of the fittings, as shown by arrow A in the figure. A surface along the visible direction may be called a "visible surface." The "visible direction" is the direction along the top and bottom perpendicular to the visible direction in the case of a bottom frame or the like that extends along the horizontal direction. In the case of a vertical frame or the like that extends along the vertical direction, the horizontal direction perpendicular to the visible direction is called the "visible direction." A surface along the visible direction may be called a "visible surface."

[0010] Figures 1 and 2 show a fitting according to an embodiment of the present invention. The fitting shown here is called a sliding window, which comprises a frame 10, and an inner screen 20A on the indoor side and an outer screen 20B on the outdoor side, which are arranged so as to be slidable left and right on the frame 10. The frame 10 is constructed by assembling an upper frame 11, a lower frame 12, and left and right vertical frames 13 on all four sides. In this embodiment, the upper frame 11, lower frame 12, and vertical frames 13 are each made of extruded shapes molded from resin.

[0011] The upper frame 11 has an upper frame base wall portion 11a extending along the front direction, an upper inner guide rail (guide rail) 11b on the indoor side and an upper outer guide rail (guide rail) 11c on the outdoor side protruding from the inner peripheral surface of the upper frame base wall portion 11a toward the inner peripheral side, and an upper inner wall portion 11d protruding from the indoor side edge of the upper frame base wall portion 11a toward the inner peripheral side. The upper inner guide rail 11b, the upper outer guide rail 11c, and the upper inner wall portion 11d have approximately the same protruding dimensions from the upper frame base wall portion 11a. In the illustrated example, the upper inner guide rail 11b and the upper outer guide rail 11c are hollow.

[0012] The lower frame 12 has a lower frame base wall portion 12a extending along the projection direction, a lower inner guide rail 12b on the indoor side and a lower outer guide rail 12c on the outdoor side protruding from the projection surface on the inner periphery side of the lower frame base wall portion 12a toward the inner periphery side, and a lower inner wall portion 12d protruding from the edge portion on the indoor side of the lower frame base wall portion 12a toward the inner periphery side. The dimension of the lower frame base wall portion 12a along the projection direction is approximately the same as that of the upper frame base wall portion 11a. The lower inner guide rail 12b is provided in a portion facing the upper inner guide rail 11b, and the lower outer guide rail 12c is provided in a portion facing the upper outer guide rail 11c. The protruding dimensions of the lower inner guide rail 12b, the lower outer guide rail 12c, and the lower inner wall portion 12d from the lower frame base wall portion 12a are substantially the same as each other and are smaller than the protruding dimension of the upper inner guide rail 11b from the upper frame base wall portion 11a. In the illustrated example, the lower inner guide rail 12b and the lower outer guide rail 12c are hollow.

[0013] The left and right vertical frames 13 are symmetrical to each other and have a vertical frame base wall portion 13a extending along the projection direction, a partition wall portion 13b protruding toward the inner periphery from a portion that is approximately the center of the projection surface on the inner periphery side of the vertical frame base wall portion 13a, and two vertical frame side wall portions 13c protruding toward the inner periphery from both side edges of the vertical frame base wall portion 13a. The dimensions of this vertical frame 13 along the projection direction are set so that the upper frame 11 and the lower frame 12 can be arranged between the vertical frame side wall portions 13c. When the upper frame 11 and the lower frame 12 are arranged between the vertical frame side wall portions 13c, the partition wall portion 13b is positioned between the upper inner guide rail 11b and the upper outer guide rail 11c and between the lower inner guide rail 12b and the lower outer guide rail 12c. The partition wall portion 13b and the two vertical frame side wall portions 13c have substantially the same protruding dimensions from the vertical frame base wall portion 13a.

[0014] The inner screen 20A and the outer screen 20B are almost symmetrical to each other, and are constructed by assembling an upper frame 21, a lower frame 22, and left and right vertical frames 23, 24 around the four sides, and attaching a rectangular panel 25 to the area surrounded by these frame members 21, 22, 23, 24. In the illustrated example, the upper frame 21 and the lower frame 22 have the same cross-sectional shape. For this reason, in the following explanation, the upper frame 21 and the lower frame 22 are collectively referred to as horizontal frames 21, 22, and the same components are given the same reference numerals. Similarly, the vertical frames 23, 24 are almost symmetrical to each other. For this reason, the components of the vertical frames 23, 24 are given the same reference numerals to each side.

[0015] As shown in Figures 1, 3, 5, and 6, the horizontal frames 21 and 22 have a horizontal frame base 26a along the front direction, two panel support walls 26b protruding in the front direction from both side edges of the horizontal frame base 26a toward the inner periphery, and a horizontal outer sight wall (outer sight wall) 26c and a horizontal inner sight wall (inner sight wall) 26d protruding in the front direction from both side edges of the horizontal frame base 26a toward the outer periphery. The horizontal outer sight wall 26c and the horizontal inner sight wall 26d are configured to have approximately the same plate thickness. The horizontal frame base 26a and the two panel support walls 26b are configured to have a plate thickness larger than the horizontal outer sight wall 26c and the horizontal inner sight wall 26d, respectively, and to be hollow. As is clear from the figure, the lateral outer sight wall 26c and the lateral inner sight wall 26d have groove forming portions 26e on their outer peripheral edge portions. The groove forming portions 26e form engagement groove portions 26f that open toward the inner peripheral side between the lateral outer sight wall 26c and the lateral inner sight wall 26d. In this embodiment, the groove forming portions 26e are provided so as to protrude toward each other from the edge portion located on the outer peripheral side of the lateral outer sight wall 26c and the edge portion located on the outer peripheral side of the lateral inner sight wall 26d, and then bend toward the inner peripheral side at approximately a right angle.

[0016] The above-mentioned horizontal frames 21, 22 have reinforcing members 30, 40 disposed between the horizontal outer sight wall portion 26c and the horizontal inner sight wall portion 26d, respectively. The reinforcing members 30, 40 are formed from metals such as aluminum alloys or steel, and are provided over almost the entire length of the horizontal frames 21, 22. In this embodiment, the reinforcing member for the upper frame 21 (hereinafter referred to as the upper reinforcing member 30 when distinguishing between them) is constituted by a bottom plate portion 31 and two mounting plate portions 32, and the reinforcing member for the lower frame 22 (hereinafter referred to as the lower reinforcing member 40 when distinguishing between them) is constituted by a projection plate portion 41 and two sight plate portions 42.

[0017] The bottom plate portion 31 of the upper reinforcement member 30 is flat and extends along the projection direction. The dimension of the bottom plate portion 31 along the projection direction is set shorter than the distance between the lateral outer sight wall portion 26c and the lateral inner sight wall portion 26d. A screw hole 33 is provided on the inner peripheral portion of the bottom plate portion 31 so as to extend along the length of the upper frame 21. The screw hole 33 is tubular and opens on the inner peripheral side.

[0018] The mounting plate portions 32 of the upper reinforcement member 30 are flat plates protruding from both side edges of the bottom plate portion 31 toward the outer periphery in a state of being almost parallel to each other. The interval between the mounting plate portions 32 is set so that the upper inner guide rail 11b and the upper outer guide rail 11c can be inserted. The outer peripheral plate portion 34 and the insertion engagement portion 35 are provided on the outer peripheral edge of the mounting plate portion 32. The outer peripheral plate portion 34 is bent in a direction away from the two mounting plate portions 32. The insertion engagement portion 35 protrudes from the edge of the outer peripheral plate portion 34 toward the outer periphery. The dimension from one insertion engagement portion 35 to the other insertion engagement portion 35 along the projection direction is almost equal to the interval between the lateral outer sight wall portion 26c and the lateral inner sight wall portion 26d.

[0019] The upper reinforcement 30 is placed between the horizontal outer sight wall 26c and the horizontal inner sight wall 26d with the upper insulation material 50 attached to the outer surfaces of the two mounting plate parts 32, and the screw holes 33 are abutted against the outer peripheral surface of the horizontal frame base 26a, and the upper reinforcement 30 is placed on the upper frame 21. From this state, the bottom plate part 31 is protruded from between the two mounting plate parts 32, and the protruding pieces 36 are engaged with the horizontal frame base 26a through the openings of the screw holes 33, thereby attaching the upper reinforcement 30 to the upper frame 21. As is clear from the figure, the protruding pieces 36 are provided at two locations along the length of the bottom plate part 31. The protruding pieces 36 are inclined so that the spacing between them gradually increases toward the inner periphery, and each tip engages with the horizontal stile base 26a, thereby functioning to prevent relative movement along the longitudinal direction of the upper reinforcement 30 with respect to the upper stile 21. The upper reinforcement 30 also functions to prevent relative movement along the projection direction of the horizontal outer sight wall 26c and the horizontal inner sight wall 26d with respect to the mounting plate 32, with the insertion engagement portion 35 of the mounting plate 32 being inserted into the engagement grooves 26f provided in the horizontal outer sight wall 26c and the horizontal inner sight wall 26d, respectively.

[0020] The upper insulation material 50 described above is thicker than the upper reinforcement material 30, and is attached to the mounting plate portion 32 over almost the entire length thereof, while being separated from both the lateral outer sight wall portion 26c and the lateral inner sight wall portion 26d. The inner peripheral edge of the upper insulation material 50 extends to the inner peripheral side beyond the bottom plate portion 31, and reaches the side of the screw hole 33, while being separated from the horizontal frame base portion 26a. In this embodiment, the upper insulation material 50 is made of foamed polyethylene, and is attached to the upper reinforcement material 30 by adhesive tape. As the upper insulation material 50, in addition to foamed polyethylene, glass wool, rock wool, hard urethane, foamed urethane, phenol, polystyrene (EPS, etc.), polyester, cellulose fiber, insulation board, wool (sheep's wool), carbonized cork, and other materials can be used.

[0021] The projection plate portion 41 of the lower reinforcement member 40 is flat and extends along the projection direction as shown in Fig. 1. The dimension of the bottom plate portion 31 along the projection direction is approximately equal to the distance between the lateral outer sight wall portion 26c and the lateral inner sight wall portion 26d. A screw hole 43 is provided on the inner peripheral portion of the projection plate portion 41 so as to extend along the length of the lower frame 22. The screw hole 43 is tubular and opens to the inner peripheral side.

[0022] The sight plate portions 42 of the lower reinforcement member 40 are flat plates that protrude toward the outer periphery in a state that they are substantially parallel to each other from both side edges of the bottom plate portion 31. The dimension along the projection direction from one sight plate portion 42 to the other sight plate portion 42 is substantially equal to the mutual distance between the lateral outer sight wall portion 26c and the lateral inner sight wall portion 26d.

[0023] The lower reinforcement 40 is disposed between the horizontal outer sight wall 26c and the horizontal inner sight wall 26d, and the screw hole 43 is abutted against the outer peripheral surface of the horizontal frame base 26a, and is disposed on the lower frame 22. In this state, the outer peripheral edge of the sight plate 42 is inserted into the engagement groove 26f provided on the horizontal outer sight wall 26c and the horizontal inner sight wall 26d, respectively, and the relative movement of the horizontal outer sight wall 26c and the horizontal inner sight wall 26d along the projection direction with respect to the sight plate 42 is prevented. Although not shown in the figure, the lower reinforcement 40 may also be inserted into the horizontal frame base 26a of the lower frame 22, and then the projection plate 41 may be subjected to protrusion processing, similar to the upper reinforcement 30. A wheel 60 is attached between the two sight plate portions 42 at an appropriate position in the longitudinal direction.

[0024] As shown in Figs. 2 and 4, the vertical frames 23 and 24 have a hollow vertical frame base 28a and two panel support walls 28b protruding in the sight direction from both side edges on the inner periphery of the vertical frame base 28a toward the inner periphery. The vertical frame base 28a is configured with a vertical inner sight wall 28c and a vertical outer sight wall 28d extending in the sight direction, and an inner periphery sight wall 28e and an outer periphery sight wall 28f extending in the sight direction. Each of the vertical frames 23 and 24 has a side reinforcement 70 disposed in the hollow of the vertical frame base 28a. The side reinforcement 70 is formed from a metal such as an aluminum alloy or steel, and is provided along the length of the vertical frames 23 and 24. In this embodiment, the side reinforcement member 70 is configured to have a bottom plate portion 71 and two mounting plate portions 72. The bottom plate portion 71 is a flat plate extending along the projection direction. The mounting plate portions 72 are flat plates protruding from both side edges of the bottom plate portion 71 so as to be approximately parallel to each other.

[0025] The side reinforcement 70 is inserted into the hollow of the vertical frame base 28a with the bottom plate 71 aligned along the projection direction, and longitudinal movement relative to the vertical frames 23, 24 is prevented by screw members provided at appropriate locations. More specifically, the side reinforcement 70 is attached to the two vertical frames 23 that form the door ends by screwing screw members S1 from the inner peripheral projection wall 28e between the panel support wall portions 28b at the vertical frame base 28a to the bottom plate 71. The side reinforcement 70 is attached to the vertical frame 24 that joins the inner sash 20A by screwing the mounting screw member S2 of the crescent lock 61 provided on the projection surface on the outer periphery to the bottom plate 71 via the outer peripheral projection wall portion 28f of the vertical frame base 28a. For the vertical frame 24 that is the joint of the outer sash 20B, the side reinforcement 70 is attached by screwing it to the mounting plate 72 on the indoor side through the vertical inner sight wall 28c of the vertical frame base 28a, using the mounting screw member S3 of the crescent receiver 62 provided on the sight surface facing the room of the vertical frame base 28a. As is clear from the figure, for the two vertical frames 24 that are the joint, the side insulation material 51 is attached to the outdoor surface of the mounting plate 72 located on the outdoor side of the side reinforcement material 70. The side insulation material 51 is the same as the upper insulation material 50 provided on the upper reinforcement material 30, and one surface is bonded to the mounting plate 72, while the other surface is arranged so that it is spaced apart from the vertical outer sight wall 28d of the vertical frame base 28a.

[0026] As shown in Fig. 1 and Fig. 2, the upper frame 21, the lower frame 22, and the left and right vertical frames 23, 24 are assembled around the four sides with the periphery of the panel 25 supported between the panel support wall portions 26b and between the panel support wall portions 28b via the glazing channel 27. More specifically, for example, between the upper frame 21 and the vertical frame 24, as shown in Figs. 4 to 6, with a corner cap 63 attached to the upper end of the vertical frame 24, the small end face of the upper frame 21 abuts against the expected surface on the inner periphery side of the vertical frame 24. From this state, the connecting screw member (screw member) S4 is screwed into the screw hole 33 provided in the upper reinforcement member 30 of the upper frame 21 through the screw insertion hole 63a of the corner cap 63, so that the upper frame 21 and the vertical frame 24 are connected to each other. After assembling the frame members 21, 22, 23, and 24 all around, as shown in Figure 1, the upper outer guide rail 11c and the upper inner guide rail 11b are inserted between the mounting plate portion 32 of the upper reinforcement member 30 provided on the upper frame 21, and then the door rollers 60 provided on the lower frame 22 are positioned on the lower outer guide rail 12c and the lower inner guide rail 12b, so that the inner screen 20A and the outer screen 20B are each arranged to be slidable left and right relative to the frame body 10.

[0027] In the fittings constructed as described above, the frame members 21, 22, 23, 24 constituting the inner screen 20A and the frame members 21, 22, 23, 24 constituting the outer screen 20B are made of resin, which is advantageous in terms of heat insulation. Moreover, the frame members 21, 22, 23, 24 on all four sides are provided with reinforcing members 30, 40, 70 made of metal, respectively, which makes it possible to improve the rigidity and heat deformation resistance of the frame members 21, 22, 23, 24. This makes it possible to improve the dimensional accuracy of the inner screen 20A and the outer screen 20B, and also to eliminate the risk of thermal deformation due to the effects of sunlight, thereby ensuring the sliding operability of each. Furthermore, the upper frame 21 and the vertical frame 24 that joins the upper frame 21 are provided with upper insulation material 50 and side insulation material 51 along the viewing direction. In particular, for the portion located on the outdoor side, the upper insulation material 50 and the side insulation material 51 are disposed along the expected direction in the portion located on the outdoor side of the reinforcing materials 30, 70. This eliminates the risk that the reinforcing materials 30, 70 formed from metal will function as a thermal bridge, and eliminates the concern that the insulation properties in the indoor and outdoor directions will be impaired.

[0028] In the above embodiment, a sliding window is exemplified as a fitting, but the present invention is not limited to this. In this case, it is not necessarily limited to a sliding screen relative to a frame. In addition, the insulation materials 50, 51 are arranged on both the upper frame 21 and the vertical frame 24 that joins the frames, but it is sufficient to arrange the insulation materials on either the upper frame, the lower frame, or the vertical frame. In this case, the insulation material may be arranged on the vertical frame 23 that becomes the door end. Furthermore, for the upper frame 21, the insulation material 50 is arranged between the reinforcing material 30 and the horizontal outer sight wall 26c, and between the reinforcing material 30 and the horizontal inner sight wall 26d, but it is sufficient to arrange the insulation material 50 on either one of them. The insulation material 50 only needs to be arranged so as to intersect with the projection direction, and it is not necessary to arrange the insulation material 50 along a direction perpendicular to the projection direction.

[0029] As described above, the building fixture of the present invention comprises a frame and a shoji screen, which is constructed with a frame material molded from resin, and the frame material has an exterior facing wall portion facing the outside of the room and an interior facing wall portion facing the inside of the room, and is characterized in that a metal reinforcing material is arranged between the exterior facing wall portion and the interior facing wall portion, and an insulating material is arranged to suppress heat transfer in the forward direction. According to this invention, the reinforcing material improves the rigidity and heat resistance of the frame material, preventing deformation of the shoji screen. Moreover, the insulation material suppresses heat transfer in the forward direction, so there is no risk of the insulation being impaired.

[0030] The present invention is also characterized in that, in the above-mentioned building fixture, the insulation material is flat and arranged between the outer visible wall portion and the inner visible wall portion in a state crossing the projected direction. According to this invention, the flat insulating material suppresses heat transfer in the forward direction.

[0031] The present invention is also characterized in that, in the above-mentioned building fixture, the reinforcing material has a mounting plate portion arranged so as to intersect in the projected direction, and the insulating material is attached to the mounting plate portion. According to this invention, since the insulating material can be arranged at the same time as the reinforcing material is arranged on the frame material, there is no risk of the work of manufacturing the shoji screen becoming complicated.

[0032] Furthermore, the present invention is characterized in that, in the above-mentioned fittings, the shoji screen is arranged slidably relative to the frame body, the frame material is an upper frame arranged opposite the upper frame of the frame body and into which the guide rail of the upper frame is inserted between the outer sight wall portion and the inner sight wall portion, the reinforcing material has two mounting plate portions arranged opposite each other with the guide rail in between, and a bottom plate portion arranged between the inner peripheral edges of the two mounting plate portions, and the insulation material is provided in the portion of at least one of the mounting plate portions that faces the outer sight wall portion or the inner sight wall portion. According to this invention, since the reinforcing material is interposed between the insulating material and the guide rail, there is no risk of the insulating material coming into contact with the guide rail.

[0033] The present invention is also characterized in that, in the above-mentioned building fixture, the reinforcing material is provided with an outer peripheral plate portion bent in a direction away from the outer peripheral side edges of the two mounting plate portions, and an insertion engagement portion protruding from the edge of the outer peripheral plate portion toward the outer peripheral side, and each of the outer facing wall portion and the inner facing wall portion is provided with an engagement groove portion into which the insertion engagement portion is inserted. According to this invention, by inserting the insert engagement portion into the engagement groove portion, the mounting plate portion of the reinforcing material can suppress deformation of the outer sight wall portion and the inner sight wall portion.

[0034] The present invention is further characterized in that, in the above-mentioned building fixture, the reinforcing material is provided with a protruding piece that protrudes from the bottom plate portion toward the inner circumference, and the tip of the protruding piece engages with the frame material, thereby preventing relative movement along the length of the frame material. According to this invention, there is no risk of the reinforcing material moving longitudinally relative to the frame material.

[0035] The present invention is also characterized in that, in the above-mentioned building fixture, screw holes are provided in the bottom plate portion of the reinforcing material along the longitudinal direction of the frame material, and the frame material and the adjacent frame material are connected to each other by screwing a screw member into the screw hole through the adjacent frame material. According to this invention, since the frame members are connected to adjacent frame members via reinforcing materials, the rigidity of the screen can be ensured regardless of the rigidity of the frame members.
