Description

[Technical field]

[0001] The present invention relates to fittings such as row windows and stepped windows that are installed on a building frame with two frames connected together. [Background technology]

[0002] For example, in fixtures with frames arranged side by side, such as multi-window windows, it is common to place a upright between the vertical frames and connect the vertical frames of each frame to the upright. In this type of fixture, each frame is connected to the building frame, and the ends of the uprights are also connected to the building frame via anchors (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2017-218806 A Summary of the Invention [Problem to be solved by the invention]

[0004] In the above-mentioned fittings, the frame and the mullion may behave differently when the building materials constituting the frame and the mullion are thermally expanded by the influence of sunlight, or when external forces are applied by the influence of wind and rain. For this reason, when a sealant is provided between the frame and the mullion, a non-adhesive partition material called a backup material is provided between the frame and the mullion before the sealant is filled, so that the sealant is in two-sided contact. When the sealant is provided so that there is two-sided contact in this way, it is possible to prevent the sealant from being cut or peeled off even when the frame and the mullion behave differently, and it is possible to ensure the watertightness of the fittings. However, it cannot be denied that the work becomes more complicated by the amount of backup material provided. Moreover, even in the case of the frame and the mullion, the dimensions must be increased by the amount of backup material provided, which not only leads to the large size of the fittings, but also has the potential to be disadvantageous in terms of appearance quality. The above-mentioned problem is not limited to when the frame is connected to the left and right, but can also occur when it is connected to the top and bottom, such as in a stepped window.

[0005] In view of the above-mentioned circumstances, the present invention aims to provide a fitting that can facilitate assembly work and ensure watertightness without increasing in size or compromising the appearance quality. [Means for solving the problem]

[0006] In order to achieve the above object, the fitting according to the present invention is a fitting in which two frame bodies are arranged side by side and attached to a building frame, and a connecting member is disposed between the two frame bodies, and the frame bodies and the connecting member are connected to each other, while only the frame body is connected to the building frame. The connecting member extends in the front direction so as to be located between the frame bodies, and has a front wall portion protruding from the front surface of the frame body facing the outside of the room, and a front wall portion provided so as to face the front surface of the frame body facing the outside of the room from the protruding edge of the front wall portion, and a sealant is provided between each of the connecting member and the frame body so as to contact three surfaces: the front wall portion of the connecting member, the front wall portion of the connecting member, and the front surface of the frame body facing the outside of the room. It is characterized by being Effect of the Invention

[0007] According to the present invention, since the connecting member is not connected to the framework, the frame and the connecting member behave in the same way when thermal expansion occurs or an external force is applied. Therefore, the seal material between the frame and the connecting member can be provided so that it is in contact with three sides, and it can be filled without the need to install a backup material in advance. As a result, not only can the work during assembly be simplified, but there is also no need to secure space for the backup material on the connecting member and the frame, which prevents the building materials from becoming larger and improves the appearance quality.

[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] FIG. 1 shows a fitting according to an embodiment of the present invention. The fitting illustrated here is called a continuous window, which is constructed by arranging two frame bodies 10A and 10B side by side and connecting them to each other with a connecting member 10C, as shown in FIG. 2. More specifically, the frame body 10A shown on the left side of FIG. 2 is constructed by disposing an upper frame 12A and a lower frame 13A between the left and right vertical frames 11A, and the frame body 10B shown on the right side of FIG. 2 is constructed by disposing an upper frame 12B and a lower frame 13B between the left and right vertical frames 11B. These frame bodies 10A and 10B are connected by a connecting member 10C between the adjacent vertical frames 11A and 11B.

[0011] The frame body located on the left side in Fig. 2 (hereinafter, for convenience when distinguishing between them, it will be referred to as the left frame body 10A, and the components of the left frame body 10A will be appropriately distinguished by adding the term "left" to them) has a joiner 14A provided in the middle of the left vertical frame 11A so as to be parallel to the left upper frame 12A and the left lower frame 13A, dividing the interior into two parts, upper and lower. As shown in Figs. 2 to 5, a shoji screen 20A is provided in the upper part surrounded by the left vertical frames 11A on the left and right, the left upper frame 12A, and the joiner 14A so as to be able to open and close. The shoji screen 20A is constructed by arranging left and right vertical frames 22A, upper frames 23A, and lower frames 24A around the four perimeters of a rectangular panel 21A. In this embodiment, an opening / closing mechanism (not shown) is provided between the left upper frame 12A and transom 14A of the left frame body 10A and the shoji screen 20A, forming a vertical sliding window that opens so that the shoji screen 20A protrudes to the outside of the room. Reference numeral 25A in the figure denotes a handle that is operated when opening or closing the vertical sliding window. A fixed window is formed by disposing a surface material 26A in the lower portion surrounded by the left and right vertical frames 11A, the transom 14A, and the left lower frame 13A. Reference numeral 27A in the figure denotes an attachment for supporting the surface material 26A on the left vertical frame 11A for the vertical sliding window.

[0012] On the other hand, in the frame body located on the right side (hereinafter, for convenience when distinguishing between the two, it will be referred to as the right frame body 10B, and the components of the right frame body 10B will be distinguished by adding the term "right" as appropriate), a fixed window is formed by disposing a panel 14B in the area surrounded by the left and right right vertical frame 11B, the right upper frame 12B, and the right lower frame 13B.

[0013] The detailed configuration of each of the frame bodies 10A, 10B and the connecting member 10C will be described below, along with a detailed description of the characteristics of the present invention. For the sake of convenience, in the following description, the respective directions will be specified in the state in which they are attached to the main body 1. Furthermore, the components constituting the frame bodies 10A, 10B and the connecting member 10C are all extruded shapes formed from metals such as aluminum alloys or resins, and are configured to have a substantially uniform cross-sectional shape along the entire length along the longitudinal direction.

The left exterior appearance wall 13Ab is a flat plate extending from the edge located on the outside of the left lower frame base plate 13Aa toward the inner periphery. The left lower protrusion 13Ac is a hollow protrusion that protrudes toward the inner periphery from the part located on the inside of the room on the projection surface that is the inner periphery of the left lower frame base plate 13Aa. The left lower door stop wall 13Ad extends almost horizontally from the inner peripheral edge of the left lower protrusion 13Ac toward the outside of the room, and then forms a thin plate shape that is bent toward the outer peripheral side, and it is possible to sandwich the surface material 26A between the left exterior appearance wall 13Ab.

The right lower frame base plate 13Ba is a flat plate extending almost horizontally along the projection direction. The right exterior appearance wall 13Bb is a flat plate extending from the edge located on the outside of the right lower frame base plate 13Ba toward the inner periphery. The right lower protrusion 13Bc is a hollow protrusion that protrudes toward the inner periphery from the part located on the inside of the room on the projection surface that is the inner periphery of the right lower frame base plate 13Ba.

The right lower anchor mounting wall 13Be extends from the middle outer peripheral surface and the room inside edge of the right lower frame base plate 13Ba toward the outer peripheral side almost parallel to each other, and then bends toward each other in a direction approaching each other, and it is possible to mount the anchor member 30 between them. The right lower anchor mounting wall 13Be provided on the outside of the room further extends so as to gradually incline downward toward the outside of the room, then bends downward, bends toward the inside of the room, and bends further downward. The right lower frame base plate 13Ba and the right lower anchor mounting wall 13Be are formed to be approximately the same dimensions as the left lower frame base plate 13Aa and the left lower anchor mounting wall 13Ae.

[0018] The left and right vertical frames 11A of the left frame body 10A are configured to be symmetrical to each other, and the right and left vertical frames 11B of the right frame body 10B are configured to be symmetrical to each other.

[0019] The left vertical frame 11A is integrally formed with the left vertical frame base plate 11Aa, the left vertical door stop wall 11Ab, and two left vertical anchor mounting walls (connecting parts) 11Ac. The left vertical frame base plate 11Aa is a flat plate extending almost vertically along the front direction. The left vertical door stop wall 11Ab is a flat plate protruding from the front surface of the inner periphery of the left vertical frame base plate 11Aa toward the inner periphery. The left vertical anchor mounting walls 11Ac extend almost parallel from the outside edge and the inside edge of the left vertical frame base plate 11Aa toward the outer periphery, respectively, and then the extending edges are bent in the direction approaching each other, and an anchor member 30 can be attached between them.

[0020] The right vertical frame 11B is integrally formed with the right vertical frame base plate 11Ba, the right vertical door stop wall 11Bb, and two right vertical anchor mounting walls (connecting parts) 11Bc. The right vertical frame base plate 11Ba is a flat plate extending almost vertically along the front direction. The right vertical door stop wall 11Bb is a flat plate protruding from the front surface of the inner periphery of the right vertical frame base plate 11Ba toward the inner periphery. The right vertical anchor mounting walls 11Bc extend almost parallel from the outside edge and the inside edge of the right vertical frame base plate 11Ba toward the outer periphery, respectively, and then the extending edges are bent in the direction approaching each other, and the anchor members 30 can be attached between them. The right vertical frame base portion 11Ba and the right vertical anchor mounting wall portion 11Bc are formed to approximately the same dimensions as the left vertical frame base portion 11Aa and the left vertical anchor mounting wall portion 11Ac.

[0021] As shown in FIG. 6, the connecting member 10C is formed by integrally forming a connecting base wall portion (front wall portion) 11Ca, an inner sight wall portion (connecting portion) 11Cb, and an outer sight wall portion (sight wall portion) 11Cc. The connecting base wall portion 11Ca is a flat plate extending almost vertically along the sight direction. The width dimension of the connecting base wall portion 11Ca along the sight direction is configured to be longer than the vertical frame base portions 11Aa and 11Ba of the vertical frames 11A and 11B. The inner sight wall portion 11Cb is a thin plate extending from the edge portion located on the indoor side of the connecting base wall portion 11Ca to the left and right along the sight direction, then bending toward the outdoor side, and further extending in the sight direction in a direction away from each other. The outer sight wall 11Cc is a flat plate extending from the edge of the connecting base wall 11Ca on the outside of the room to the left and right in the sight direction. The extension length of the outer sight wall 11Cc in the sight direction is set to a dimension sufficiently smaller than that of the inner sight wall 11Cb. More specifically, it is formed to have a dimension sufficient to fill and harden the sealing material 40 described later. In addition, the connecting base wall 11Ca is provided with an engaging protrusion 11Cd and an engaging fin portion (connecting portion) 11Ce on the surface facing the left vertical frame 11A and the surface facing the right vertical frame 11B, respectively. The engaging protrusion 11Cd is a longitudinal protrusion configured to abut against the bent end surface of the vertical anchor mounting wall 11Ac, 11Bc when the vertical anchor mounting wall 11Ac, 11Bc on the room side of the vertical frames 11A, 11B abuts against the exterior facing surface of the inner sight wall 11Cb. The engaging fin 11Ce protrudes from the surface of the connecting base wall 11Ca and then bends toward the outside of the room. A groove is provided between the bent portion of the engaging fin 11Ce that extends outside the room and the connecting base wall 11Ca, into which the bent portion of the vertical anchor mounting wall 11Ac, 11Bc can be inserted. These engaging fin portions 11Ce are formed in positions such that the bent portions of the vertical anchor mounting wall portions 11Ac, 11Bc can engage when the vertical anchor mounting wall portions 11Ac, 11Bc on the indoor side of the vertical frames 11A, 11B are abutted against the indoor facing surface of the inner facing wall portion 11Cb.

[0022] The left frame body 10A and the right frame body 10B described above are connected to each other in a state of being arranged side by side by engaging the vertical anchor mounting walls 11Ac, 11Bc provided on the respective vertical frames 11A, 11B with the engaging projections 11Cd and engaging fins 11Ce of the connecting member 10C, and further by screwing the screws 41 into the vertical frames 11A, 11B via the inner sight wall 11Cb. It is preferable to cover and hide the screws 41 by attaching a cover member 42 to the inner sight wall 11Cb after screwing the screws 41 into it. The left frame body 10A and the right frame body 10B, which are connected to each other via the connecting member 10C, are attached to the building skeleton 1 by attaching anchor members 30 to the upper frames 12A, 12B, lower frames 13A, 13B, and vertical frames 11A, 11B on the outer periphery, respectively, and then fixing the anchor members 30 to the building skeleton 1. The positions at which the anchor members 30 are attached may be, for example, two locations on the upper frames 12A, 12B, two locations on the lower frames 13A, 13B, and two locations on the vertical frames 11A, 11B, as shown by the triangular marks in Fig. 7. As described above, the connecting member 10C does not have a structure equivalent to the anchor attachment wall portion provided on the frame bodies 10A, 10B. In other words, only the left vertical frame 11A of the left frame body 10A and the right vertical frame 11B of the right frame body 10B are connected to the main body 1, and there are no connection points between the connecting member 10C and the main body 1.

[0023] A sealant 40 is filled between the connecting member 10C and the vertical frames 11A, 11B of the respective frame bodies 10A, 10B and cured to ensure watertightness between them. More specifically, the sealant 40 is filled and cured in a recessed groove portion surrounded by a connecting base wall portion 11Ca that protrudes outside the room beyond the vertical frames 11A, 11B of the frame bodies 10A, 10B in the connecting member 10C, an outer sight wall portion 11Cc, and the sight surfaces of the vertical frames 11A, 11B that face the outside of the room.

[0024] Here, as described above, the connecting member 10C provided between the left frame body 10A and the right frame body 10B is not connected to the frame body 1, so that when thermal expansion occurs or an external force is applied, the frame bodies 10A, 10B and the connecting member 10C will exhibit the same behavior. Therefore, even if the seal material 40 is provided between the frame bodies 10A, 10B and the connecting member 10C so that they are in three-sided contact without providing a backup material, there is no risk of the seal material being cut or peeled off due to thermal expansion or external force. This eliminates the need to provide a backup material, making it possible to simplify the assembly work and ensure the watertightness of the fixture. In addition, as described above, it is possible to provide the seal material 40 between the outer visible wall portion 11Cc, which has a small visible dimension, and the vertical frames 11A, 11B, which prevents the fixture from becoming large and improves the appearance quality.

[0025] (Modification) The seal material 40 provided between the connecting member 10C and the frame bodies 10A, 10B is not necessarily limited to that in the embodiment. For example, as in the modified example shown in FIG. 8, the seal material 40 can be provided between the vertical frames. Below, a modified example in which the seal material is provided between the vertical frames will be described. In the following, it is assumed that the left frame body 10A and the right frame body 10B each have vertical frames 11A, 11B that are substantially similar to those in the embodiment. Therefore, the same reference numerals are used for the configurations that are common to the embodiment, and detailed description of each will be omitted.

[0026] The connecting member 110C is formed by integrally forming a connecting base wall portion (front wall portion) 111Ca, an inner sight wall portion (connecting portion) 111Cb, and an outer sight wall portion (sight wall portion) 111Cc. The connecting base wall portion 111Ca is a thin plate extending almost vertically along the front direction. The width dimension of the connecting base wall portion 111Ca along the front direction is configured to be smaller than the vertical frame base portions 11Aa and 11Bb of the vertical frames 11A and 11B. The inner sight wall portion 111Cb is a thin plate extending from the edge portion located on the indoor side of the connecting base wall portion 111Ca to the left and right along the sight direction, and then bent toward the indoor side. The outer sight wall portion 111Cc is a flat plate formed by bending the edge portion located on the outdoor side of the connecting base wall portion 111Ca. As is clear from the figure, the connecting base wall 111Ca has a bent portion 111Cd in the portion located on the outside of the room, and is configured so that the center in the left-right direction of the outer sight wall 111Cc is located on an extension of the portion located on the inside of the room. The extension length of the outer sight wall 111Cc along the sight direction is set to a dimension sufficiently smaller than that of the inner sight wall 111Cb. In addition, the connecting base wall 111Ca is provided with engagement walls 111Ce on the surface facing the left vertical frame 11A and the surface facing the right vertical frame 11B, and engagement fins (connecting portions) 111Cf are provided on both sides of the outer sight wall 111Cc. The engaging wall portion 111Ce is configured to abut on the outer peripheral surface of the bent portion of the vertical anchor mounting wall portion 11Ac, 11Bc when the vertical anchor mounting wall portion 11Ac, 11Bc on the indoor side of the vertical frame 11A, 11B abuts on the indoor surface of the inner sight wall portion 111Cb. The engaging fin portion 111Cf protrudes to the left and right from both sides of the outer sight wall portion 111Cc and then bends toward the outdoor side, and is configured to have a dimension that allows the bent portion of the vertical anchor mounting wall portion 11Ac, 11Bc to be inserted. These engaging fin portions 111Cf are formed at positions where the bent portion of the vertical anchor mounting wall portion 11Ac, 11Bc can be engaged when the vertical anchor mounting wall portion 11Ac, 11Bc on the indoor side of the vertical frame 11A, 11B abuts on the indoor surface of the inner sight wall portion 111Cb.

[0027] In this modification, the left frame body 10A and the right frame body 10B are connected to each other in a state of being arranged side by side by side by engaging the vertical anchor mounting walls 11Ac, 11Bc provided on the respective vertical frames 11A, 11B with the engaging projections 11Cd and engaging fins 111Cf of the connecting member 110C, and further by screwing the screws 141 into the vertical frames 11A, 11B through the inner sight wall 111Cb. It is preferable to cover the screws 141 by attaching a cover member 142 to the inner sight wall 111Cb after screwing the screws 141. Although not shown in the figure, the left frame body 10A and the right frame body 10B connected to each other through the connecting member 110C are attached to the building frame by attaching anchor members to the upper frame, lower frame, and vertical frame on the outer periphery, respectively, and then fixing the anchor members to the building frame. The position where the anchor members are attached may be the same as in the embodiment. Also in the modified example, the connecting member 110C does not have a structure equivalent to the anchor attachment wall portion provided on the frame bodies 10A and 10B, and only the left frame body 10A and the right frame body 10B are connected to the frame body. There are no connection points between the connecting member 110C and the frame body.

[0028] The sealing material 40 between the connecting member 110C and the vertical frames 11A, 11B of each frame body 10A, 10B may be filled into the groove portion surrounded by the visible surface of the outer visible wall portion 111Cc of the connecting member 110C facing the outside of the room and the opposing visible surfaces of the vertical frames 11A, 11B on the outside of the room beyond the outer visible wall portion 111Cc, that is, the visible surfaces on the outer periphery side at the bent portions of the vertical anchor mounting wall portions 111Ac, 111Bc, and allowed to harden.

[0029] Here, as described above, the connecting member 110C provided between the left frame body 10A and the right frame body 10B is not connected to the frame structure, so that when thermal expansion occurs or an external force is applied, the frame bodies 10A, 10B and the connecting member 110C will exhibit the same behavior. Therefore, even if the seal material 40 is provided between the frame bodies 10A, 10B and the connecting member 110C so as to be in three-sided contact without providing a backup material, there is no risk of the seal material being cut or peeled off due to thermal expansion or external force. This eliminates the need to provide a backup material, making it possible to simplify the assembly work and ensure the watertightness of the fixtures. In addition, since the seal material 40 and the backup material are not arranged side by side in the expected direction, the expected dimensions of the frame bodies 10A, 10B can be set to be short, making it possible to prevent the frame bodies 10A, 10B from becoming large.

[0030] In the above-mentioned embodiment, the fittings are exemplified in which the frame bodies 10A and 10B are arranged side by side and connected to each other via a connecting member 10C extending in the vertical direction, but the present invention is not limited to this. For example, as shown in FIG. 9, the present invention can also be applied to a fitting in which two frame bodies 210A and 210B are arranged side by side vertically and the upper lower frame 213A of the upper frame body 210A and the lower upper frame 212B of the lower frame body 210B are connected to each other via a connecting member 210C extending in the horizontal direction and attached to a building frame. In this case, only the upper frame body 210A and the lower frame body 210B are connected to the building frame. In other words, connection parts 230 with the main body are provided only on the two upper vertical frames 211A and the upper upper frame 212A of the upper frame body 210A, and connection parts 230 with the main body are provided only on the two lower vertical frames 211B and the lower lower frame 213B of the lower frame body 210B, and no connection points are provided between the connecting member 210C and the main body.

[0031] In addition, in the above-described embodiment, a transom 14A is provided in the left frame body 10A to form a vertical sliding window at the top and a fixed window at the bottom, and a fixed window is provided in the right frame body 10B, but the configurations provided inside the frame bodies 10A and 10B are not limited to these.

[0032] Furthermore, in the above-described embodiment, the connecting member 10C is configured to connect only the vertical frames 11A, 11B between the frame bodies 10A, 10B, but it may also be configured to connect the connecting member 10C to the upper frames 12A, 12B or the lower frames 13A, 13B.

[0033] As described above, the building fixture of the present invention is a building fixture in which two frame bodies are arranged side by side and attached to a main body, and is characterized in that a connecting member is arranged between the two frame bodies, and the frame bodies and the connecting member are connected to each other, while only the frame body is connected to the main body. According to this invention, since the connecting member is not connected to the framework, when thermal expansion occurs or an external force is applied, the frame body and the connecting member behave in the same way. Therefore, the sealant between the frame body and the connecting member can be provided so that they are in contact on three sides, and it is sufficient to fill the gap without having to place the back-up material in advance. As a result, not only can the assembly work be simplified, but there is also no need to secure space for the back-up material on the connecting member and the frame body, which prevents the building materials from becoming larger and improves the appearance quality.

[0034] The present invention is also characterized in that, in the above-mentioned building fixture, the frame body and the connecting member are provided with connecting portions that connect them to each other, and anchor members that connect them to the main body are provided only on the frame body. According to this invention, the frame body and the connecting member are connected to each other by the connecting portion, and are connected to the main body only by the anchor member of the frame body.

[0035] The present invention is also characterized in that, in the above-mentioned building fixture, the connecting member extends in the prospective direction so as to be positioned between the frame bodies, and has a prospective wall portion protruding from the prospective surface of the frame body, and a visible wall portion arranged from the protruding edge of the prospective wall portion to face the prospective surface of the frame body, and a sealing material is provided between each of the connecting members and the frame bodies so as to contact three surfaces: the prospective wall portion of the connecting member, the visible wall portion of the connecting member, and the visible surface of the frame body. According to this invention, there is no need for a backup material arranged in parallel with the sealing material in the visibility direction, so the visibility dimension of the projecting wall portion of the connecting member protruding from the frame body can be set short, which is advantageous in terms of appearance quality.

[0036] The present invention is also characterized in that, in the above-mentioned building fixture, the connecting member has a visible wall portion extending in the visible direction so as to be positioned between the frame bodies, and a visible wall portion extending in the visible direction at the extending edge of the visible wall portion, each of the frame bodies has visible surfaces facing each other at a position protruding further than the visible wall portion, and a sealing material is provided between the connecting member and each of the frame bodies so as to contact three surfaces, the visible wall portion of the connecting member and the visible surfaces of each of the frame bodies. According to this invention, there is no need for a backup material arranged in parallel with the sealing material in the projected direction, so that the projected dimensions of the frame body can be set short, making it possible to prevent the frame body from becoming larger.
