Description

[Technical Field]

[0001] The present invention relates to a fitting comprising two frames connected to each other. [Background technology]

[0002] Some fixtures are constructed by interconnecting multiple frames, such as stepped windows and row windows. In this type of fixture, the dimensions of the adjacent frame members of two frame members are generally matched along the projected direction, and a connecting member is disposed between these frame members, and the two frame members are connected via the connecting member (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 11-190169 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, when a sliding window, which has multiple rows of rails supporting slidable shoji screens in the projection direction, and a fixed window, which has only one panel, are used as standalone fixtures (hereinafter referred to as single windows), their dimensions along the projection direction are different. In other words, the dimensions along the projection direction of a sliding window are generally larger than those of a fixed window. Therefore, when using the above-mentioned connecting structure to construct stepped or continuous windows, the reality is that a special frame material with a larger dimension along the projection direction is prepared for the fixed window, which is not necessarily desirable from the perspective of manufacturing costs.

[0005] In view of the above circumstances, the present invention aims to provide a fitting having connected frame bodies while suppressing increases in manufacturing costs. [Means for solving the problem]

[0006] In order to achieve the above-mentioned objective, the building fixture of the present invention is a building fixture comprising two frame bodies connected to each other while arranged side by side in the front direction, wherein the adjacent frame materials of the two frame bodies have different dimensions along the front direction, and connecting materials are interposed between these adjacent frame materials to connect each frame material while leaving a joint between them, and a sealing material is arranged in the joint. [Effects of the Invention]

[0007] According to the present invention, frame materials with different dimensions along the projected direction are connected to each other, so that frame materials for single windows can be used as they are, making it possible to construct stepped windows or continuous windows while keeping manufacturing costs down.

DETAILED DESCRIPTION OF THE INVENTION

[0009] Preferred embodiments of the fittings according to the present invention will be described in detail below with reference to the accompanying drawings. Note that, for convenience, the terms "invisible direction" and "visible direction" will be used below. The "invisible direction" is the direction along the depth of the fittings, as indicated by arrow A in the drawings. A surface along the invisible direction will be referred to as a "visible face." The "visible direction" is the direction perpendicular to the invisible direction in the case of an object that extends horizontally, such as a sill. In the case of an object that extends vertically, such as a vertical frame, the "visible direction" is the horizontal direction perpendicular to the invisible direction. A surface along the invisible direction will be referred to as a "visible face."

[0010] (Embodiment 1) 1 to 4 show a fitting that is a first embodiment of the present invention. The fitting illustrated here is called a stepped window, constructed by interconnecting a sliding window W1 and a fixed window W2 that are arranged side by side above and below along the front direction. The upper sliding window W1 is constructed by arranging three shoji screens 20 slidably inside a frame 10. The lower fixed window W2 is constructed by arranging three fixed panels 40 inside a frame 30. These sliding window W1 and fixed window W2 can also be used as single windows. The configurations of the sliding window W1 and the fixed window W2 will be explained below.

[0011] The frame of the sliding window W1 (hereinafter referred to as the upper frame 10 when distinguishing between them) is constructed by assembling an upper frame 11, an upper frame 12, and upper vertical frames 13 on both sides. The upper frame 11, the upper frame 12, and the upper vertical frames 13 are constructed so that their dimensions along the projection direction are the same.

[0012] The upper frame 11 has an upper frame base 11a with a hollow rectangular cross section and three rows of upper rails 11b provided along the length of the inner peripheral surface of the upper frame base 11a. A plurality of screw holes 11c are provided inside the upper frame base 11a for connecting to the upper vertical frame 13.

[0013] The upper frame 12 comprises a plate-shaped frame base 12a and three rows of lower rails 12b arranged longitudinally on the inner peripheral surface of the frame base 12a. Each of the three rows of lower rails 12b is positioned opposite the upper rail 11b. The frame base 12a has an outer hollow 12c and an outer engagement piece 12d on its exterior edge, and an inner engagement piece 12e on its interior edge. The outer hollow 12c is a substantially rectangular cross-sectioned cavity located on the outer periphery of the frame base 12a. The outer engagement piece 12d extends substantially horizontally from the interior peripheral edge of the outer hollow 12c. The inner engagement piece 12e extends from the frame base 12a toward the exterior and then extends substantially horizontally toward the exterior. Screw holes 12f for connecting to the upper vertical frame 13 are provided on the visible surface on the outer periphery of the lower frame base 12a and inside the outer hollow portion 12c.

[0014] The upper vertical frame 13 is configured to have a vertical frame base 13a having a hollow rectangular cross section, and a single vertical rail 13b provided so as to protrude inward from the projected surface on the inner periphery of the vertical frame base 13a. In this embodiment 1, the upper vertical frame 13 located on the left side as viewed from the inside of the room has the vertical rail 13b provided in a portion corresponding to the upper rail 11b and lower rail 12b on the outside of the room, and the upper vertical frame 13 located on the right side as viewed from the inside of the room has the vertical rail 13b provided in a portion corresponding to the upper rail 11b and lower rail 12b on the inside of the room.

[0015] Each of the three shoji screens 20 of the sliding window W1 is constructed by supporting a glass panel 24 or the like inside a frame body made up of an upper frame 21, a lower frame 22, and left and right vertical frames 23 assembled around all four sides. The upper frame 21 is provided with a guide groove 21a in which the upper rail 11b is positioned, and the lower frame 22 is provided with a door roller 25 that can roll on the lower rail 12b. These shoji screens 20 are disposed between the upper rail 11b and the lower rail 12b of the upper frame body 10, and can slide left and right. In the illustrated example, the shoji screen disposed between the upper rail 11b and the lower rail 12b on the outermost side of the room (hereinafter referred to as outer shoji screen 20A when distinguishing between them) has a vertical guide groove 23a in the left vertical frame 23 that accommodates the vertical rail 13b. Furthermore, the shoji screen positioned between the upper rail 11b and the lower rail 12b closest to the interior (hereinafter referred to as the inner shoji screen 20B for distinction) has a vertical guide groove 23a on the right side of the vertical frame 23 that accommodates the vertical rail 13b. When viewed from inside the room, the outer shoji screen 20A is positioned on the left side, the inner shoji screen 20B is positioned on the right side, and the shoji screen positioned between the upper rail 11b and the lower rail 12b in the middle (hereinafter referred to as the middle shoji screen 20C for distinction) is positioned in the center, the internal opening of the upper frame body 10 is blocked. In this state, the vertical frame 23 located on the right side of the outer shoji screen 20A and the vertical frame 23 located on the left side of the middle shoji screen 20C overlap in the projection direction, and the vertical frame 23 located on the left side of the inner shoji screen 20B and the vertical frame 23 located on the right side of the middle shoji screen 20C also overlap in the projection direction.

[0016] The frame of the fixed window W2 (hereinafter referred to as the lower frame 30 when distinguishing between them) is constructed by assembling a lower upper frame 31, a lower lower frame 32, and left and right lower vertical frames 33 all around, with two mullions 34 provided between the lower upper frame 31 and the lower lower frame 32. The dimensions of the lower frame 30 along the left and right are the same as those of the upper frame 10. The dimensions of the lower upper frame 31, lower lower frame 32, lower vertical frames 33, and mullions 34 along the projection direction are the same, and are smaller than those of the sliding window W1 (almost half the size in the example shown).

[0017] The lower upper frame 31 comprises a hollow upper frame base 31a with a rectangular cross section and a panel support piece 31b extending inward from the inner peripheral edge located on the exterior side of the upper frame base 31a. The upper frame base 31a has an outer ledge engagement piece 31c and an inner ledge engagement piece 31d on its inner peripheral surface, and screw holes 31e are provided within the hollow interior for connection to the lower vertical frame 33. The outer ledge engagement piece 31c extends inward from the exterior side of the upper frame base 31a and then bends toward the interior. The inner ledge engagement piece 31d extends inward from the interior side edge of the upper frame base 31a and then bends toward the exterior. The outer ledge engaging piece 31c and the inner ledge engaging piece 31d are configured to have approximately the same dimensions, and the dimension of their protrusion toward the interior side is smaller than that of the panel support piece 31b.

[0018] The lower frame 32 comprises a flat frame base 32a and a panel support piece 32b extending inward from the exterior edge of the frame base 32a. The frame base 32a has an outer ledge engagement piece 32c and an inner ledge engagement piece 32d on its inner surface, and an outer engagement piece 32e and an inner engagement piece 32f on its outer surface. The outer ledge engagement piece 32c extends inward from the exterior edge of the frame base 32a and then bends toward the room. The inner ledge engagement piece 32d extends inward from the interior edge of the frame base 32a and then bends toward the outside. The outer ledge engagement piece 32c and the inner ledge engagement piece 32d are approximately the same dimensions, but their protrusion toward the interior is smaller than that of the panel support piece 32b. The outer engaging piece 32e and the inner engaging piece 32f each extend from the lower frame base 32a toward the outer periphery and then extend almost horizontally toward each other. Screw holes 32g for connecting to the lower vertical frame 33 are provided on the projected surface of the outer periphery of the lower frame base 32a.

[0019] The lower vertical frame 33 comprises a vertical frame base 33a with a hollow rectangular cross section and a panel support piece 33b extending inward from the inner peripheral edge of the vertical frame base 33a located on the exterior side of the room. The vertical frame base 33a is provided with an outer ledge engagement piece 33c and an inner ledge engagement piece 33d on its inner peripheral surface. The outer ledge engagement piece 33c extends inward from the exterior side of the vertical frame base 33a and then bends toward the room. The inner ledge engagement piece 33d extends inward from the interior edge of the vertical frame base 33a and then bends toward the outside. The outer ledge engagement piece 33c and the inner ledge engagement piece 33d are approximately the same dimensions, but their protrusion toward the interior is smaller than that of the panel support piece 33b.

[0020] The mullion 34 comprises a hollow, rectangular-shaped mullion base 34a and two panel support pieces 34b extending away from each other from both exterior edges of the mullion base 34a. The mullion base 34a is provided with an outer ledge engagement piece 34c and an inner ledge engagement piece 34d on each of its two visible sides. The outer ledge engagement piece 34c extends from the exterior edge of the mullion base 34a and then bends toward the room. The inner ledge engagement piece 34d extends from the interior edge of the mullion base 34a and then bends toward the outside. The outer ledge engagement piece 34c and the inner ledge engagement piece 34d are approximately the same dimensions, but their interior protrusion is smaller than that of the panel support piece 34b.

[0021] The above-mentioned lower frame body 30 has flanges 35 attached to each of the outer flange engagement pieces 31c, 32c, 33c, 34c and inner flange engagement pieces 31d, 32d, 33d, 34d, and the four peripheral edges of the FIX panel 40 are supported between the flanges 35 and each of the panel support pieces 31b, 32b, 33b, 34b via sealing members 36.

[0022] The connecting member 50 connecting the upper frame 10 of the sliding window W1 and the lower frame 30 of the fixed window W2 is integrally formed with a connecting member base (hollow portion) 50a, a first connecting portion 50b, and a second connecting portion 50c. The connecting member base 50a has a hollow rectangular cross section. The dimension of the connecting member base 50a along the projection direction is smaller than the dimension of the lower upper frame 31 along the projection direction. A lower engaging protrusion 50d is provided on the underside of the connecting member base 50a, protruding downward from the portion located closer to the interior side of the room. The first connecting portion 50b extends upward along the projection direction from the upper edge of the connecting member base 50a located on the interior side of the room, and then extends toward the interior side. An upper engaging protrusion 50e is provided on the upper portion of the first connecting portion 50b, protruding upward. The dimension of the first connecting portion 50b along the projection direction is approximately the same as the dimension of the inner engagement piece 12e provided on the upper lower frame 12 along the projection direction. The second connecting portion 50c extends gradually downward from the upper edge located on the outdoor side of the connecting material base 50a toward the outside of the room, then extends approximately horizontally toward the outside of the room, and then bends upward. The horizontally extending portion of the second connecting portion 50c is smaller than the dimension of the lower upper frame 31 along the projection direction and is located above the underside of the connecting material base 50a. An attachment groove 50f is provided at the upper part of the upwardly bent portion of the second connecting portion 50c facing the outside of the room, opening toward the outside.

[0023] To connect the upper frame 10 and the lower frame 30 using this connecting material 50, the second connecting portion 50c is brought into contact with the visible surface on the outer periphery of the lower upper frame 31, and the visible surface of the connecting material base 50a facing outside is brought into contact with the visible surface of the lower upper frame 31 facing inside the room. From this state, screws S1 are screwed into the lower upper frame 31 via the second connecting portion 50c, as shown in Figures 6 and 7. Thereafter, the outer engaging piece 12d of the upper lower frame 12 is inserted into the mounting groove 50f, and the inner engaging piece 12e is brought into contact with the upper surface of the connecting material base 50a and the visible surface of the first connecting portion 50b facing outside. From this state, screws S2 are screwed into the upper lower frame 12 via the first connecting portion 50b. As shown in FIG. 8, it is preferable to attach a water-stopping material C to the hollow lower end of the vertical frame base 13a of the upper vertical frame 13 and the hollow upper end of the vertical frame base 33a of the lower vertical frame 33, respectively.

[0024] Between the upper lower frame 12 and the lower upper frame 31, which are connected by the connecting material 50, a joint 60 is secured in the portion facing the outside of the room, and a sealant 61 is filled in this joint 60. In other words, a gap that will become the joint 60 is secured between the projected surface on the outer periphery of the outer engaging piece 12d inserted into the mounting groove 50f and the projected surface on the outer periphery of the lower upper frame 31, and a sealant 61 is filled between the outer engaging piece 12d and the lower upper frame 31 to close the joint 60.

[0025] Furthermore, in this first embodiment, a cover member 70 is provided on the portion of the connecting material 50 that is exposed indoors. The cover member 70 is formed by integrally molding a front cover portion 70a and a rear cover portion 70b. The front cover portion 70a is a flat portion that is sized to continuously cover the area from the underside of the connecting material base portion 50a to the protruding edge of the first connecting portion 50b. An upper cover piece 70c is provided on the upper edge of the front cover portion 70a facing outside. The upper cover piece 70c covers the upper portion of the first connecting portion 50b that extends indoors. An upper engagement protrusion 70d is provided on the extending edge of the upper cover piece 70c so as to protrude downward. The rear cover portion 70b extends approximately horizontally from the lower edge of the front cover portion 70a toward the outside of the room. The extension dimension of the concealed cover portion 70b is approximately equal to the total dimension from the portion of the first connecting portion 50b located on the indoor side to the visible surface of the connecting material base 50a located on the outdoor side. A lower engaging protrusion 70e is provided on the upper surface of the concealed cover portion 70b in a portion corresponding to the lower engaging protrusion 50d of the connecting material base 50a.

[0026] This cover member 70 is attached so that the upper cover piece 70c is placed on the upper surface of the portion of the first connecting portion 50b that extends into the room, and the recessed cover portion 70b is placed on the underside of the connecting material base 50a, thereby covering the connecting material 50 exposed between the upper lower frame 12 and the lower upper frame 31. At this time, the upper engaging protrusion 70d is engaged with the upper engaging protrusion 50e, and the lower engaging protrusion 70e is engaged with the lower engaging protrusion 50d of the connecting material 50, so the cover member 70 will not inadvertently fall off.

[0027] The stepped window constructed by connecting the sliding window W1 and the fixed window W2 as described above is fixed to an opening in the main body B via the upper upper frame 11, upper vertical frame 13, lower vertical frame 33, and lower lower frame 32. This stepped window prevents rainwater and other outdoor water from seeping inside the room because the joint 60 between the upper lower frame 12 and the lower upper frame 31 is filled with a sealant 61. Furthermore, the connecting material 50 is not exposed to the interior, which is advantageous in terms of design from the inside. Furthermore, because the lower frame 30 of the single-pane fixed window W2 is used as is and connected to the sliding window W1, parts can be shared, preventing increased manufacturing costs.

[0028] Furthermore, because the lower upper frame 31, which has a smaller dimension along the projection direction, is connected to the upper lower frame 12, which has a larger dimension along the projection direction, at a portion approximately midway along the projection direction, there is no risk of deformation, such as twisting, occurring in the upper lower frame 12. For example, if the lower upper frame 31 is connected to the upper lower frame 12 so that it is biased toward the interior side, the weight of the shoji screen 20 will be biased toward the exterior side relative to the lower upper frame 31 supporting the upper lower frame 12, raising concerns that the portion of the upper lower frame 12 located on the exterior side will be twisted downward. In contrast, as in the first embodiment, when the lower upper frame 31 is connected to a portion approximately midway along the upper lower frame 12, the weight of the shoji screen 20 is balanced relative to the lower upper frame 31 and applied to the upper lower frame 12, eliminating the risk of deformation in the upper lower frame 12. Additionally, the provision of a hollow connecting member base 50a in the connecting member 50 more reliably prevents deformation of the upper lower frame 12.

[0029] (Embodiment 2) Figures 9 and 10 show fittings according to a second embodiment of the present invention. The fittings illustrated here are called stepped windows, constructed by interconnecting a fixed window W2 and a sliding window W1 arranged side by side above and below along the front view direction. The upper fixed window W2 is constructed by arranging three fixed panels 40 inside a frame 30, and the lower sliding window W1 is constructed by arranging three shoji screens 20 slidably inside a frame 10. Each of these fixed window W2 and sliding window W1 can also be used as a single window. Since this second embodiment uses a fixed window W2 and sliding window W1 with the same configuration as in the first embodiment, the same reference numerals are used and detailed description of each will be omitted. However, for the fixed window W2, they are referred to as the upper frame body 30, the upper upper frame 31, the upper lower frame 32, and the upper vertical frame 33, and for the sliding window W1, they are referred to as the lower frame body 10, the lower upper frame 11, the lower lower frame 12, and the lower vertical frame 13.

[0030] The connecting member 80 connecting the upper frame 30 of the fixed window W2 and the lower frame 10 of the sliding window W1 is formed by integrally molding a reference plate 80a, a first connecting portion 80b, and a second connecting portion 80c. The reference plate 80a is a flat plate extending approximately horizontally along the projection direction. The dimension of the reference plate 80a along the projection direction is approximately the same as the horizontally extending portion of the inner engagement piece 32f provided on the upper lower frame 32. The first connecting portion 80b extends vertically from the edge of the reference plate 80a located on the interior side of the room, and then both the upper and lower edges extend toward the interior side. The portion of the first connecting portion 80b extending toward the interior side is provided with an engagement protrusion 80d that protrudes outward from the outer surface. The dimension along the projection direction of the portion of the first connecting portion 80b that extends above the reference plate 80a is set slightly smaller than the dimension along the projection direction of the inner engagement piece 32f. The second connecting portion 80c extends gradually downward from the edge of the reference plate 80a located on the exterior side of the room, then extends approximately horizontally toward the exterior, and then bends upward. The horizontally extending portion of the second connecting portion 80c is smaller than the mutual distance between the outer engagement piece 32e and the inner engagement piece 32f provided on the upper lower frame 32, and is located above the lower edge of the reference plate 80a. An attachment groove 80e is provided at the upper part of the upwardly bent portion of the second connecting portion 80c that faces the exterior and opens toward the exterior.

[0031] To connect the upper frame 30 and the lower frame 10 using this connecting material 80, the second connecting portion 80c is brought into contact with the visible surface on the outer periphery of the lower upper frame 11, and the visible surface facing outside of the portion of the first connecting portion 80b below the reference plate 80a is brought into contact with the visible surface facing inside of the lower upper frame 11, and from this state, the screw S3 is screwed into the lower upper frame 11 via the second connecting portion 80c. Thereafter, the outer engaging piece 32e of the upper lower frame 32 is inserted into the mounting groove 80e, and the inner engaging piece 32f is brought into contact with the upper surface of the reference plate 80a and the visible surface facing outside of the first connecting portion 80b, and from this state, the screw S4 is screwed into the upper lower frame 32 via the first connecting portion 80b.

[0032] Between the upper lower frame 32 and the lower upper frame 11, which are connected by the connecting material 80, a joint 90 is secured in the portion facing the outside of the room, and this joint 90 is filled with a sealant 91. In other words, a gap that serves as the joint 90 is secured between the projected surface on the outer periphery of the outer engaging piece 32e inserted into the mounting groove 80e and the projected surface on the outer periphery of the lower upper frame 11, and a sealant 91 is filled between the outer engaging piece 32e and the lower upper frame 11 to close the joint 90.

[0033] Furthermore, in the second embodiment, a cover member 100 is provided on the portion of the connecting material 80 that is exposed indoors. The cover member 100 is formed by integrally molding a flat cover base 100a that extends vertically along the projection direction and engagement pieces 100b that extend from both the upper and lower edges of the cover base 100a toward the outside of the room. The dimension of the cover base 100a along the projection direction is formed to be a dimension that can cover the first connecting portion 80b. Engagement protrusions 100c are provided on the extending edges of the engagement pieces 100b at portions that face each other.

[0034] This cover member 100 is attached so that the engaging piece portion 100b covers the first connecting portion 80b, thereby covering the connecting material 80 exposed between the upper lower frame 32 and the lower upper frame 11. At this time, the upper and lower engaging protrusion portions 100c are engaged with the engaging protrusion portions 80d, respectively, so the cover member 100 will not accidentally fall off.

[0035] The stepped window, constructed by connecting the fixed window W2 and the sliding window W1 as described above, is fixed to an opening in the main body B via the upper frame 31, upper vertical frame 33, lower vertical frame 13, and lower frame 12. This stepped window eliminates the risk of rainwater or other outdoor water seeping into the interior of the room because the joint 90 between the upper frame 32 and the lower frame 11 is filled with sealant 91. Furthermore, the connecting material 80 is not exposed to the interior, which is advantageous in terms of design from the interior side. Furthermore, because the upper frame 30 of the single-pane fixed window W2 is used as is and connected to the sliding window W1, parts can be shared, preventing increased manufacturing costs.

[0036] In the above-described embodiment, an example is given of a window having two frame bodies arranged side by side, one above the other, but it is also possible to have two frame bodies arranged side by side, or two or more frame bodies. The two frame bodies to be connected are not limited to sliding windows and fixed windows. Furthermore, in the case of a window having a sliding window, there is no need for three shoji screens. Furthermore, in the case of a fixed window, there is no need for a mullion, and there is no need for the panel to be supported via a batten.

[0037] As described above, the building fixture of the present invention is a building fixture comprising two frame bodies connected to each other while arranged side by side in the viewing direction, wherein the adjacent frame materials of the two frame bodies have different dimensions along the viewing direction, and between these adjacent frame materials there is interposed a connecting material which connects to each frame material while leaving a joint between them, and a sealing material is disposed in the joint. According to this invention, frame materials with different dimensions along the projected direction are connected to each other, so that frame materials for single windows can be used as they are, making it possible to construct stepped windows or continuous windows while keeping manufacturing costs down.

[0038] The present invention is also characterized in that, in the above-mentioned building fixture, the connecting material has a first connecting portion that is connected to one of the frame materials at a facing side toward the interior of the room, and a second connecting portion that is connected to the other frame material at a facing side toward the outer periphery. According to this invention, the two frame bodies are connected via the first connecting portion and the second connecting portion.

[0039] Furthermore, the present invention is characterized in that in the above-mentioned fitting, the connecting material has a hollow portion between the first connecting portion and the second connecting portion. According to this invention, since a hollow portion is interposed between the two frame bodies, it is possible to prevent the frame material from being deformed.

[0040] The present invention is also characterized in that, in the above-mentioned building fixture, the two frame bodies are arranged side by side, one above the other, and the upper lower frame of the frame body arranged above has a larger dimension along the projection direction than the lower upper frame of the frame body arranged below. According to this invention, a stepped window can be constructed that has a frame body at the top that has a large dimension along the projection direction.

[0041] Furthermore, the present invention is characterized in that, in the above-mentioned fittings, the visible surface of the lower upper frame facing the interior of the room is positioned further outside the room than the visible surface of the upper lower frame facing the interior of the room, and the visible surface of the lower upper frame facing the exterior of the room is positioned further inside the room than the visible surface of the upper lower frame facing the exterior of the room. According to this invention, the lower frame material, which has a smaller dimension along the projection direction, is connected to the upper frame material, which has a larger dimension along the projection direction, at a part that is approximately midway in the projection direction, so there is no risk of deformation such as twisting in the upper frame material.
