Description

[Technical field]

[0001] The present invention relates to fittings. [Background technology]

[0002] When attaching a frame to a main body, a commonly used structure is to provide plate-like members called nail fins on each of the frame materials such as the upper frame and vertical frames, and then screw the plate-like members into the outer surface of the main body facing the outside (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 5-179864 Summary of the Invention [Problem to be solved by the invention]

[0004] However, a waterproof sheet is provided between the body and the frame to ensure watertightness. In the above-mentioned mounting structure of the frame, the plate-like member of the frame is superimposed on the outer surface of the body, and a step is formed between the plate-like member and the outer surface of the body, which raises the concern that pinholes may occur in the waterproof sheet.

[0005] In view of the above-mentioned circumstances, the present invention has an object to provide a fitting capable of improving watertightness between a frame body and a main body. [Means for solving the problem]

[0006] In order to achieve the above-mentioned objective, the fitting of the present invention is a fitting that is attached to an opening in a main body with a portion of the frame material that constitutes a frame protruding toward the outside of the room further than the outer surface of the main body facing the outside, and is characterized in that the portion on the outer periphery of the frame material is provided with an outer edge surface that faces the outside, located on the inside of the room further than the portion of the frame material that protrudes to the outside, and the outer edge surface is juxtaposed to the outer surface of the main body within the opening in the main body. Effect of the Invention

[0007] According to the present invention, since the outer edge surface is provided on the part of the frame material that is on the inner periphery side of the body, it is possible to arrange the outer surface of the body and the outer edge surface side by side without a step between them. This allows a waterproof sheet to be provided from the outer surface of the body to the outer edge surface of the frame material without the occurrence of pinholes, making it possible to improve watertightness. Moreover, even if the outer surface of the body is covered with an exterior material, the frame body can be removed without destroying the exterior material, which has the advantage of facilitating the work of renovating the building fixtures.

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] 1 to 3 show a fitting according to an embodiment of the present invention. The fitting shown here is called a single-sliding window, and is composed of a frame 10, a fixed screen 20 and a movable screen 30 attached to the frame 10. The frame 10 is composed of an upper frame (frame material) 11, a lower frame 12, and left and right vertical frames (frame materials) 13, 14 assembled on all four sides. Inside the frame 10, a upright 15 is arranged between the upper frame 11 and the lower frame 12 along the vertical direction. The upper frame 11, the lower frame 12, and the left and right vertical frames 13, 14 that constitute the frame 10 are configured so that the dimensions along the front direction are almost the same. In contrast, the upright 15 is configured so that the dimensions along the front direction are smaller than those of the upper frame 11, and is attached to the outside of the room at a position that is almost equidistant from the left and right vertical frames 13, 14.

[0011] As shown in Figures 1 and 3, the fixed shoji screen 20 is constructed by disposing a panel 21 of double-glazed glass or the like in the area surrounded by the upper frame 11, lower frame 12, one vertical frame 13, and upright 15. In this embodiment, the fixed shoji screen 20 is provided between the vertical frame located on the right side when viewed from inside the room (hereinafter referred to as the right vertical frame 13 when distinguishing between them) and the upright 15. The movable shoji screen 30 is constructed by attaching an upper frame 32, a lower frame 33, and left and right vertical frames 34, 35 to the four periphery of a rectangular panel 31 of double-glazed glass or the like, and is disposed so as to be slidable left and right along the part of the frame 10 that is on the inside of the room relative to the upright 15. When the movable shoji screen 30 is placed in the closed position relative to the frame body 10, the vertical frame 34 located on the right side as viewed from inside the room is arranged side by side in the forward direction relative to the upright 15, and the vertical frame 35 located on the left side as viewed from inside the room and the vertical frame located on the left side as viewed from inside the room (hereinafter referred to as the left vertical frame 14 when distinguishing between them) are abutted against each other via the weatherstripping material 1.

[0012] In this fitting, the upper frame 11, lower frame 12, left and right vertical frames 13, 14, and upright 15 are made of wood or wood-based material (hereinafter simply referred to as wood, etc.) and have wooden frame molding parts 11A, 12A, 13A, 14A, 15A on the indoor side, and metal frame molding parts 11B, 12B, 13B, 14B, 15B on the outdoor side made of metal such as aluminum alloy. The upper frame 11, right vertical frame 13, and upright 15 are fitted with wooden battens 2 made of wood, etc., on the inner periphery of the wooden frame molding parts 11A, 13A, 15A, which is on the indoor side. The upper edge and both left and right side edges of the panel 21 of the fixed shoji 20 are sandwiched between the wooden battens 2 of the wooden frame molding parts 11A, 13A, 15A and the metal frame molding parts 11B, 13B, 15B. The lower edge of the panel 21 of the fixed shoji screen 20 is sandwiched between two metal battens 3, 4 attached to the metal frame molding portion 12B of the bottom frame 12.

[0013] Similarly, the upper frame 32, lower frame 33, and left and right vertical frames 34, 35 are each made of wood or the like, and have wooden frame molding parts 32A, 33A, 34A, 35A on the indoor side, and metal frame molding parts 32B, 33B, 34B, 35B on the outdoor side, made of metal such as aluminum alloy. The wooden frame molding parts 32A, 33A, 34A, 35A have wooden battens 5 made of wood or the like attached to the inner periphery and indoor side of the wooden frame molding parts 32A, 33A, 34A, 35A. The panel 31 of the movable shoji screen 30 described above has its four edges sandwiched between the wooden battens 5 of the wooden frame molding parts 32A, 33A, 34A, 35A and the metal frame molding parts 32B, 33B, 34B, 35B.

[0014] As is clear from Figures 1 to 3, in the fitting of this embodiment, the upper frame 11, lower frame 12, and left and right vertical frames 13, 14 constituting the frame 10 are attached to the opening b2 of the frame B in a state in which they each protrude outside the room beyond the outer surface b1 of the frame B facing the outside. Of these, the lower frame 12 is configured with a metal frame molding part 12B from the part that protrudes outside the room to the part that is arranged within the opening b2 of the frame B, and the wood frame molding part 12A is provided only in the part that is on the room side beyond the upright 15. In contrast, the upper frame 11 and the left and right vertical frames 13, 14 are attached to the frame B in a state in which parts of the wood frame molding parts 11A, 13A, 14A protrude outside the room beyond the outer surface b1 of the frame B. The following describes the respective configurations of the upper frame 11 and the left and right vertical frames 13, 14 of the frame body 10 and their mounting structure to the main body B, and also details the characteristic features of the present invention.

[0015] As shown in Figs. 1 to 7, the wooden frame forming part 11A of the upper frame 11 and the wooden frame forming parts 13A, 14A of the vertical frames 13, 14 are configured so that the parts along the entire length of each have a substantially uniform cross-sectional shape. In this embodiment, the wooden frame forming part 11A of the upper frame 11 and the wooden frame forming parts 13A, 14A of the vertical frames 13, 14 are configured so as to have a cross-sectional shape surrounded by six planes. That is, the wooden frame forming part 11A of the upper frame 11 and the wooden frame forming parts 13A, 14A of the vertical frames 13, 14 each have a cross-sectional shape having an inner peripheral visible surface 41 on the inner peripheral side, an indoor visible surface 42 facing the room, a first outer peripheral visible surface 43 on the outer peripheral side, a first outdoor visible surface 44 facing the outside, a second outer peripheral visible surface 45 on the outer peripheral side, and a second outdoor visible surface 46 facing the outside. The dimension of the inner peripheral projection surface 41 along the projection direction is equal to the sum of the dimension of the first outer peripheral projection surface 43 along the projection direction and the dimension of the second outer peripheral projection surface 45 along the projection direction. An inner peripheral engagement groove 41a opening to the inner peripheral side is formed along the longitudinal direction at the edge of the inner peripheral projection surface 41 located on the outside of the room. The dimension of the interior projection surface 42 along the projection direction is equal to the sum of the dimension of the first exterior projection surface 44 along the projection direction and the dimension of the second exterior projection surface 46 along the projection direction, and is smaller than the dimension of the inner peripheral projection surface 41 along the projection direction. The interior projection surface 42 is provided with a frame mounting groove 42a for mounting a frame 47 made of wood or the like on the outer peripheral side. The first outer peripheral projection surface 43 is provided on the interior side of the wood frame forming parts 11A, 13A, 14A, and the dimension along the projection direction is greater than 1 / 2 of the dimension of the inner peripheral projection surface 41 along the projection direction. An outer periphery engagement groove 43a opening to the outer periphery is formed along the longitudinal direction on the edge of the first outer periphery projection surface 43 located on the outside of the room. The first exterior projection surface 44 is provided on the outer periphery, and its dimension along the projection direction is greater than half the dimension along the projection direction of the interior projection surface 42. An inclined surface 44a is provided only on the wooden frame molding portion 11A of the upper frame 11 at the intersection between the second outer periphery projection surface 45 and the first exterior projection surface 44. The above-mentioned wooden frame molding portions 11A, 13A, 14A can be constructed, for example, by cutting one corner of a prismatic member having a rectangular cross section into a rectangular parallelepiped shape to form a step portion 48.

[0016] The metal frame molding part 11B of the upper frame 11 is integrally formed with an outer peripheral sight plate part 51, an outer peripheral engagement plate part 52, an outer peripheral sight plate part 53, a support leg plate part 54, a screw hole 55, an inner peripheral sight plate part 56, an inner peripheral sight plate part 57, a sight cover fin part 58, and an inward protruding plate part 59. The outer peripheral sight plate part 51 extends along the sight direction. The dimension of the outer peripheral sight plate part 51 along the sight direction is almost equal to the dimension along the sight direction from the first outer peripheral sight surface 43 to the upper edge position of the inclined surface 44a in the wooden frame molding part 11A of the upper frame 11. At two positions on the sight surface of the outer peripheral sight plate part 51 facing the room, ribs 51a are provided along the longitudinal direction to be abutments with the first exterior sight surface 44 of the wooden frame molding part 11A. The outer peripheral engagement plate portion 52 extends from the edge located on the outer peripheral side of the outer peripheral sight plate portion 51 toward the room, and then bends at an almost right angle toward the inner peripheral side. The outer peripheral sight plate portion 53 extends almost horizontally in the sight direction from the edge located on the inner peripheral side of the outer peripheral sight plate portion 51 toward the outside of the room, and then inclines slightly toward the inner peripheral side toward the outside of the room. The dimension along the sight direction of the outer peripheral sight plate portion 53 is configured to be larger than the dimension along the sight direction from the first exterior sight surface 44 to the second exterior sight surface 46 in the wooden frame molding portion 11A of the upper frame 11. The extending edge portion of the outer peripheral sight plate portion 53 is bent toward the inner peripheral side. The support leg plate portion 54 protrudes toward the inner peripheral side from the sight surface located on the inner peripheral side of the outer peripheral sight plate portion 53. The dimension along the projection direction from the outer peripheral sight plate portion 51 to the support leg plate portion 54 is set to be smaller than the dimension along the projection direction from the first exterior appearance surface 44 to the second exterior appearance surface 46. The screw hole 55 protrudes downward from a portion of the projection surface on the inner periphery of the outer peripheral sight plate portion 53 that is closer to the interior side than the support leg plate portion 54, and is approximately cylindrical with an opening on the inner periphery side. The protruding dimension of the screw hole 55 from the outer peripheral sight plate portion 53 is approximately the same as that of the support leg plate portion 54. The inner peripheral sight plate portion 56 extends in the projection direction from a portion of the projection surface on the inner periphery of the outer peripheral sight plate portion 53 that is closer to the exterior side than the support leg plate portion 54 toward the inner periphery side. The dimension along the projection direction from the outer peripheral sight plate portion 51 to the inner peripheral sight plate portion 56 is set to be larger than the dimension along the projection direction from the first exterior appearance surface 44 to the second exterior appearance surface 46.The dimension along the sight direction from the outer peripheral sight plate portion 53 to the extended edge of the inner peripheral sight plate portion 56 is approximately equal to the dimension along the sight direction from the upper edge position of the inclined surface 44a to the inner peripheral sight surface 41. The inner peripheral sight plate portion 57 extends in the sight direction from the edge on the inner peripheral side of the inner peripheral sight plate portion 56 toward the inside of the room. The extended edge of the inner peripheral sight plate portion 57 is bent toward the outer peripheral side. The dimension from the bent edge of the inner peripheral sight plate portion 57 to the bent edge of the outer peripheral engagement plate portion 52 is approximately equal to the dimension along the sight direction from the outer peripheral side engagement groove 43a to the inner peripheral side engagement groove 41a. The sight cover fin portion 58 extends in the sight direction from the edge on the inner peripheral side of the inner peripheral sight plate portion 56 toward the outside of the room, and then extends in the sight direction toward the inner peripheral side. The inward protruding plate portion 59 extends from the extended edge of the sight cover fin portion 58 toward the room. The extending edge of the inwardly protruding plate portion 59 is provided with a pocket portion 59a that opens toward the interior of the room.

[0017] The metal frame molding parts 13B, 14B of the vertical frames 13, 14 are integrally molded with an outer peripheral sight plate part 61, an outer peripheral engagement plate part 62, an outer peripheral sight plate part 63, an inner peripheral sight plate part 64, and an inner peripheral sight plate part 65. The outer peripheral sight plate part 61 extends along the sight direction. The dimension of the outer peripheral sight plate part 61 along the sight direction is slightly smaller than the dimension along the sight direction from the first outer peripheral sight surface 43 to the second outer peripheral sight surface 45 in the wooden frame molding parts 13A, 14A of the vertical frames 13, 14. At two positions on the sight surface of the outer peripheral sight plate part 61 facing the room, ribs 61a are provided along the longitudinal direction to be abutments with the first exterior sight surface 44 of the wooden frame molding parts 13A, 14A. The outer peripheral engagement plate part 62 extends from the edge located on the outer peripheral side of the outer peripheral sight plate part 61 toward the room, and then bends toward the inner peripheral side at approximately a right angle. The outer peripheral sight plate portion 63 extends from the edge of the inner peripheral side of the outer peripheral sight plate portion 61 toward the outside of the room in a substantially horizontal direction. The dimension of the outer peripheral sight plate portion 63 along the sight direction is configured to be larger than the dimension along the sight direction from the first exterior sight surface 44 to the second exterior sight surface 46 in the wooden frame forming portion 13A, 14A of the vertical frame 13, 14. The inner peripheral sight plate portion 64 extends in the sight direction from the sight surface on the inner peripheral side of the outer peripheral sight plate portion 63 toward the inner peripheral side, and then extends in a curved manner toward the room. The extending edge of the part of the inner peripheral sight plate portion 64 extending toward the room is provided with a pocket portion 64a that opens toward the room. The dimension along the sight direction from the outer peripheral sight plate portion 61 to the inner peripheral sight plate portion 64 is set to be larger than the dimension along the sight direction from the first exterior sight surface 44 to the second exterior sight surface 46. The dimension along the sight direction from the outer periphery sight plate portion 63 to the edge located on the inner periphery side of the inner periphery sight plate portion 64 is larger than the dimension along the sight direction from the second outer periphery sight surface 45 to the inner periphery sight surface 41. The inner periphery sight plate portion 65 extends in the sight direction from the sight surface of the inner periphery sight plate portion 64 facing the room toward the room. The extending edge portion of the inner periphery sight plate portion 65 is bent toward the outer periphery side. The dimension along the sight direction from the outer periphery sight plate portion 63 to the inner periphery sight plate portion 65 is slightly larger than the dimension from the second outer periphery sight surface 45 to the inner periphery sight surface 41.The dimension from the bent edge of the inner peripheral projection plate portion 65 to the bent edge of the outer peripheral engagement plate portion 62 is approximately equal to the dimension along the projection direction from the outer peripheral engagement groove 43a to the inner peripheral engagement groove 41a.

[0018] The metal frame molding part 11B of the upper frame 11 described above is maintained in a state of being attached to the wooden frame molding part 11A of the upper frame 11 by engaging the bent extension part of the outer peripheral engagement plate part 52 with the outer peripheral side engagement groove 43a and engaging the bent extension part of the inner peripheral projection plate part 57 with the inner peripheral side engagement groove 41a, as shown in Figures 4 and 5. In this state, the outer peripheral projection plate part 51 abuts against the first exterior projection surface 44 via the rib 51a, and the outer peripheral projection plate part 53 abuts against the second outer peripheral projection surface 45 via the support leg plate part 54, and the outer peripheral projection plate part 51 provides an outer edge surface 11a facing the outside of the room along the projection direction on the outer peripheral side of the upper frame 11. In the wooden frame molding part 11A of the upper frame 11, an upper guide rail 11C is arranged along almost the entire length of the inner peripheral projection surface. The upper guide rail 11C cooperates with the lower guide rail 12C provided on the lower frame 12 to guide the sliding of the movable shoji screen 30. In the portion of the wooden frame molding part 11A of the upper frame 11 between the upright 15 and the right vertical frame 13, the above-mentioned wooden batten 2 is provided so as to protrude inward on the inner peripheral surface, and the upper edge of the panel 21 is sandwiched between this wooden batten 2 and the inward protruding plate part 59 provided on the metal frame molding part 11B of the upper frame 11 via the tight material 6. In the portion of the wooden frame molding part 11A of the upper frame 11 between the upright 15 and the left vertical frame 14, the cover support member 11D is provided so as to protrude inward on the inner peripheral surface, and the cover member 11E is provided between this cover support member 11D and the inward protruding plate part 59 provided on the metal frame molding part 11B of the upper frame 11.

[0019] Similarly, the metal frame molding parts 13B, 14B of the vertical frames 13, 14 are maintained in a state of being attached to the wooden frame molding parts 13A, 14A of the vertical frames 13, 14 by engaging the bent extension part of the outer peripheral engagement plate part 62 with the outer peripheral side engagement groove 43a and by engaging the bent extension part of the inner peripheral projection plate part 65 with the inner peripheral side engagement groove 41a as shown in Figures 6 and 7. In this state, the outer peripheral sight plate part 61 is in a state of being abutted against the first exterior sight surface 44 via the rib 61a, and the outer peripheral sight plate part 61 provides the outer edge surfaces 13a, 14a that face the outside of the room along the sight direction on the outer peripheral side of the vertical frames 13, 14. The above-mentioned wooden batten 2 is provided so as to protrude inward on the inner peripheral visible surface of the wooden frame molding part 13A of the right vertical frame 13, and the right edge of the panel 21 is sandwiched between this wooden batten 2 and an inner peripheral sight plate part 64 provided on the metal frame molding part 13B of the right vertical frame 13, with a timber material 6 interposed between them. The left edge of the panel 21 is sandwiched between the wooden batten 2 attached to the upright 15 and the metal frame molding part 15B of the upright 15, with a timber material 6 interposed between them. The inner peripheral visible surface of the wooden frame molding part 14A of the left vertical frame 14 is provided so as to protrude inward, and a cover member 14E is provided between this cover support member 14D and the inner peripheral sight plate part 64 provided on the metal frame molding part 14B of the left vertical frame 14. In addition, the prospective surface on the inner periphery of the wooden frame molding portion 15A of the upright 15 is covered by a cover member 15E provided between it and the metal frame molding portion 15B.

[0020] As shown in Figures 4 and 6, the above-mentioned upper frame 11 and the left and right vertical frames 13, 14 are placed in the opening b2 of the body B with their respective outer edge surfaces 11a, 13a, 14a positioned on the same plane as the outer surface b1 of the body B facing the outside, and are attached to the body B by screwing the screw members S from their respective inner peripheries toward the body B. A waterproof sheet WP is provided on the outer edge surface 11a of the upper frame 11 and the outer edge surfaces 13a, 14a of the vertical frames 13, 14 from the outer surface b1 of the body B. This makes it possible to prevent water from outside from entering the room through the gaps between the body B and the upper frame 11 and between the body B and the vertical frames 13, 14. In particular, according to the upper frame 11 and the vertical frames 13, 14 of the embodiment, the outer surface b1 of the body B and the respective outer edge surfaces 11a, 13a, 14a are located on the same plane and are arranged side by side without any steps between them, so that the waterproof sheet WP can be provided from the outer surface b1 of the body B to the outer edge surfaces 11a, 13a, 14a without pinholes or bending in the middle, thereby improving watertightness. Then, the exterior wall material EM is arranged on the outside so as to face the outer edge surfaces 11a, 13a, 14a of the upper frame 11 and the vertical frames 13, 14 from the outer surface b1 of the body B, and the seal material ES is filled between the end faces of the exterior wall material EM and the respective outer peripheral projection board parts 53, 63.

[0021] With the fittings constructed as above, as shown in Figures 5(b) and 7(a), when carrying out renovations, the waterproof sheet WP between the building structure B is cut, and the seal material ES between the building structure and the exterior wall material EM is cut, making it possible to remove the upper frame 11 and vertical frames 13, 14 to the inside of the room without destroying the exterior wall material EM. This makes it possible to facilitate the work during renovations and shorten the construction period.

[0022] In the above-mentioned embodiment, the upper frame 11 and the lower frame 12 are made of wood frame molding parts 11A, 12A, 13A, 14A, 15A made of wood or the like, and metal frame molding parts 11B, 12B, 13B, 14B, 15B made of metal, which is advantageous in terms of heat insulation, but the present invention is not limited to this. For example, it may be made of a material other than wood or metal, such as a resin, and it can be applied to fittings with a frame material made of a single material.

[0023] In the above embodiment, the frame 10 is disposed so that the outer peripheral surfaces 11a, 13a, and 14a are located on the same plane as the outer surface b1 of the body B, but even if they are slightly misaligned, there is no risk of pinholes being formed and it is not a major problem. In addition, although the outer peripheral surfaces 11a, 13a, and 14a are shown as being flat, they may also be curved. In addition, when the flat outer peripheral surfaces 11a, 13a, and 14a are provided, they may be inclined with respect to the outer surface b1 of the body B.

[0024] Furthermore, in the above-mentioned embodiment, the outer edge surfaces 11a, 13a, 14a are provided on the top frame 11 and the left and right vertical frames 13, 14, but it is sufficient to provide them on at least one frame material. In this case, the outer edge surface may be provided on the bottom frame 12. Furthermore, although a single-sliding window is shown as an example, it is possible to apply this to other window types. In this case, the fixture does not necessarily have to have a shoji screen with a frame assembly.

[0025] As described above, the fitting of the present invention is a fitting that is attached to an opening in a main body with a portion of the frame material that constitutes the frame protruding toward the outside of the room further than the outer surface of the main body facing the outside, and is characterized in that the outer periphery of the frame material is provided with an outer edge surface that faces the outside at a position that is closer to the inside of the room than the portion of the frame material that protrudes to the outside, and that the outer edge surface is juxtaposed to the outer surface of the main body within the opening in the main body. According to this invention, since the outer edge surface is provided on the part of the frame material that is on the inner periphery side of the body, it is possible to arrange the outer surface of the body and the outer edge surface side by side without any step between them. This allows a waterproof sheet to be provided from the outer surface of the body to the outer edge surface of the frame material without creating pinholes, making it possible to improve watertightness. Moreover, even if the outer surface of the body is covered with an exterior material, the frame body can be removed without destroying the exterior material, which has the advantage of facilitating the work of renovating the building fixtures.

[0026] The present invention is also characterized in that, in the above-mentioned fitting, the outer edge surface is configured as a plane extending in the observation direction along the outer surface of the main body. According to this invention, the outer edge surface is positioned on the same plane as the outer surface of the main body, which makes it possible to further facilitate the work of installing the waterproof sheet and improve watertightness.

[0027] The present invention is also characterized in that, in the above-mentioned fitting, a waterproof sheet is provided between the outer edge surface and the outer surface of the structure. According to this invention, the watertightness between the frame material and the main body can be improved by the waterproof sheet that is tightly fitted over the outer edge surface of the frame material and the outer surface of the main body.
