Description

[Technical field]

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

[0002] When constructing a frame or a shoji screen using vertical and horizontal members, the horizontal members are connected to the projection surface of the vertical members via the small end face. A sealing material formed in a sheet is usually placed between the vertical and horizontal members to ensure the desired watertightness of the joint between the two (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Utility Model Application Publication No. 57-174681 Summary of the Invention [Problem to be solved by the invention]

[0004] Incidentally, some building materials that take thermal insulation into consideration have non-metallic molded parts made of resin or wood, in addition to metal molded parts made of metal such as aluminum alloy as vertical and horizontal members. In other words, by providing non-metallic molded parts on the inside of the room, it is possible to prevent condensation from forming on the frame or shoji screen even when there is a temperature difference between the inside and outside of the room.

[0005] Here, the vertical members and horizontal members are not necessarily connected to the same material, and there are cases where a metal molded part is connected to a nonmetallic molded part. For this reason, for example, when a horizontal member is connected to a nonmetallic molded part of a vertical member via a metal molded part, there is a concern that the metal molded part, which is the small end face of the horizontal member, may bite into the nonmetallic molded part of the vertical member, which is made of resin or wood, depending on the state of threading of the screw member, causing deformation. If such a situation occurs, it may be difficult to ensure watertightness between the vertical members and the horizontal members, and other problems may occur. In particular, when the nonmetallic molded part is made of wood, water may enter the inside through the biting part, causing early decay.

[0006] In view of the above-mentioned circumstances, the present invention has an object to provide a fitting that can be connected to a horizontal member without causing deformation of the vertical member. [Means for solving the problem]

[0007] In order to achieve the above-mentioned object, the building fixture of the present invention comprises vertical members and horizontal members, the vertical members having a first molded portion and the horizontal members having a second molded portion having a harderness than the first molded portion, and the horizontal members are connected via their small end faces to the projected surfaces that are on the inner periphery of the vertical members at positions where the first molded portion and the second molded portion correspond to each other, and a reinforcing plate having a harderness than the first molded portion is interposed between the first molded portion and the second molded portion. Effect of the Invention

[0008] According to the present invention, a reinforcing plate having a harder hardness than the first molded portion is interposed between the first molded portion of the vertical member and the second molded portion of the horizontal member, so that even when a screw member is screwed into the vertical member and the horizontal member, there is no risk of the horizontal member being deformed, such as by being bitten into the vertical member.

[0010] 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."

[0011] 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.

[0012] 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.

[0013] 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 rivets 3, 4 attached to the metal frame molding portion (second molding portion) 12B of the bottom frame 12.

[0014] 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.

[0015] 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. Below, the respective configurations of the upper frame 11, the left and right vertical frames 13, 14, and the lower frame 12 of the frame body 10 and the mounting structure to the main body B will be explained, and the characteristic parts of the present invention will also be described in detail.

[0016] The wooden frame forming part 11A of the upper frame 11 and the wooden frame forming parts (first 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.

[0017] The metal frame molding part 11B of the upper frame 11 is formed by integrally molding the outer peripheral sight plate part 51, the outer peripheral engagement plate part 52, the outer peripheral sight plate part 53, the support leg plate part 54, the screw hole 55, the inner peripheral sight plate part 56, the inner peripheral sight plate part 57, the sight cover fin part 58, and the 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. The outer peripheral engagement plate part 52 extends from the edge part located on the outer peripheral side of the outer peripheral sight plate part 51 toward the room, and then bends toward the inner peripheral side at almost a right angle. The outer peripheral projection board portion 53 extends almost horizontally from the edge on the inner periphery of the outer peripheral sight board portion 51 toward the outside of the room in the projection direction, and then inclines slightly toward the inner periphery toward the outside of the room. The dimension of the outer peripheral sight board portion 53 along the projection direction is configured to be larger than the dimension along the projection direction from the first exterior appearance surface 44 to the second exterior appearance surface 46 in the wooden frame molding portion 11A of the upper frame 11. The extending edge of the outer peripheral sight board portion 53 is bent toward the inner periphery. The support leg board portion 54 protrudes toward the inner periphery from the projection surface on the inner periphery of the outer peripheral sight board portion 53. The dimension along the projection direction from the outer peripheral sight board portion 51 to the support leg board 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 holes 55 protrude downward from a portion of the outer peripheral projection plate portion 53 that is closer to the room than the support leg plate portion 54, and are generally cylindrical with an opening on the inner peripheral side. The protruding dimension of the screw holes 55 from the outer peripheral projection 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 sight direction from a portion of the inner peripheral projection plate portion 53 that is closer to the room outside than the support leg plate portion 54 toward the inner peripheral side. The dimension along the sight 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 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 peripheral sight plate portion 53 to the extended edge portion 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 projection plate portion 57 extends from the inner peripheral edge of the inner peripheral sight plate portion 56 in the projection direction toward the inside of the room. The extending edge of the inner peripheral projection plate portion 57 is bent toward the outer peripheral side. The dimension from the bent edge of the inner peripheral projection plate portion 57 to the bent edge of the outer peripheral engagement plate portion 52 is approximately equal to the dimension along the projection direction from the outer peripheral side engagement groove 43a to the inner peripheral side engagement groove 41a. The sight cover fin portion 58 extends from the inner peripheral side edge of the inner peripheral sight plate portion 56 in the projection direction toward the outside of the room, and then extends in the projection direction toward the inner peripheral side. The inward protruding plate portion 59 extends from the extending edge of the sight cover fin portion 58 toward the room. The extending edge of the inward protruding plate portion 59 is provided with a pocket portion 59a that opens toward the room.

[0018] The metal frame molding part (third molding part) 13B, 14B of the vertical frame 13, 14 is formed by integrally molding the outer peripheral sight plate part 61, the outer peripheral engagement plate part 62, the outer peripheral sight plate part 63, the inner peripheral sight plate part 64, and the 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 part 13A, 14A of the vertical frame 13, 14. The outer peripheral engagement plate part 62 extends from the edge part located on the outer peripheral side of the outer peripheral sight plate part 61 toward the room, and then bends at a substantially right angle toward the inner peripheral side. The outer peripheral sight plate part 63 extends from the edge part located on the inner peripheral side of the outer peripheral sight plate part 61 toward the outside of the room in the sight direction, almost horizontally. 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 periphery of the outer peripheral sight plate portion 63 toward the inner periphery, 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 peripheral projection plate portion 63 to the edge located on the inner peripheral side of the inner peripheral projection plate portion 64 is larger than the dimension along the sight direction from the second outer peripheral projection surface 45 to the inner peripheral projection surface 41. The inner peripheral projection plate portion 65 extends in the sight direction from the sight surface of the inner peripheral projection plate portion 64 facing the room toward the room. The extended edge of the inner peripheral projection plate portion 65 is bent toward the outer peripheral side. The dimension along the sight direction from the outer peripheral projection plate portion 63 to the inner peripheral projection plate portion 65 is slightly larger than the dimension from the second outer peripheral projection surface 45 to the inner peripheral projection 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 sight direction from the outer peripheral side engagement groove 43a to the inner peripheral side engagement groove 41a.

[0019] 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. In this state, the outer peripheral sight plate part 51 abuts against the first exterior sight surface 44, 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 sight plate part 51 provides an outer edge surface 11a facing the outside of the room along the sight 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.

[0020] Similarly, the metal frame molding parts 13B, 14B of the vertical frames 13, 14 are maintained 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. In this state, the outer peripheral sight plate part 61 is in contact with the first exterior sight surface 44, and the outer peripheral sight plate part 61 provides the outer edge surfaces 13a, 14a facing the outside 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.

[0021] The above-mentioned upper frame 11 and 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 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.

[0022] On the other hand, as described above, the lower frame 12 is composed of the metal frame molding part 12B from the part protruding to the outside of the room to the part arranged in the opening b2 of the body B, and the wood frame molding part 12A is provided only in the part that is on the inside of the room from the upright 15. However, the metal frame molding part 12B of the lower frame 12 has an outside part 22 and an inside part 23, and these outside part 22 and inside part 23 are connected by two-stage bridge materials 24, 25 molded with resin. Therefore, although the dimension along the projection direction of the metal frame molding part 12B is large, there is no risk of the insulation property of the lower frame 12 being impaired. This lower frame 12 is attached between the vertical frames 13, 14 by screwing a screw member into the screw hole 12a of the lower frame 12 through the vertical frames 13, 14 with the small end surface facing the recessed parts 13F, 14F provided on the inner periphery of the vertical frames 13, 14.

[0023] Here, as shown in Fig. 4 to Fig. 6, the proportion of the wooden frame molding parts 13A, 14A is larger than that of the metal frame molding parts 13B, 14B in the projection direction of the vertical frames 13, 14. Therefore, when the small end face of the lower frame 12 is attached directly at a position facing the projection face of the vertical frames 13, 14, the metal frame molding part 12B of the lower frame 12 is connected to the wooden frame molding parts 13A, 14A of the vertical frames 13, 14, and depending on the state of screw engagement, there is a concern that the metal frame molding part 12B, which becomes the small end face of the lower frame 12, may be deformed by being bitten into the wooden frame molding parts 13A, 14A of the vertical frames 13, 14. For this reason, in the fitting of this embodiment, a reinforcing plate 70 made of a metal such as an aluminum alloy is disposed on the wooden frame molding parts 13A, 14A of the vertical frames 13, 14 to prevent the above-mentioned problem from occurring. More specifically, as shown in Figs. 7 to 9, a flat reinforcing plate 70 is provided on the portion from the metal frame molding portion 13B, 14B to the wood frame molding portion 13A, 14A on the prospective surface on the inner periphery side of the vertical frames 13, 14. The position where the reinforcing plate 70 is provided on the wood frame molding portion 13A, 14A may be a portion corresponding to the screw hole 12a provided on the metal frame molding portion 12B of the lower frame 12. The reinforcing plate 70 does not necessarily have to be provided on the portion corresponding to the metal frame molding portion 12B of the lower frame 12 other than the screw hole 12a. Then, as shown in Figs. 10 to 12, a sealing member 71 formed in a planar shape is provided on the surface of the reinforcing plate 70, and in this state, the small end surface of the lower frame 12 is abutted against the sealing member 71, and a screw member is screwed into the screw hole 12a via the vertical frames 13, 14. With this type of fittings, a reinforcing plate 70 is interposed between the metal frame molding portion 12B of the bottom frame 12 and the vertical frames 13, 14, so even if the screw members are screwed in tightly, the metal frame molding portion 12B of the bottom frame 12 will not bite into the wooden frame molding portions 13A, 14A of the vertical frames 13, 14, and there is no risk of the watertightness between them being compromised.

[0024] In the above-mentioned embodiment, the reinforcing plate 70 is interposed between the metal frame molding parts 13B, 14B of the vertical frames 13, 14 and the wooden frame molding parts 13A, 14A, but for example, as in the modified example shown in Figures 13 to 17, the reinforcing plate 72 may be provided only on the wooden frame molding parts 13A, 14A of the vertical frames 13, 14. That is, in the modified fitting, first, as shown in Figures 13 and 14, a recess 73 corresponding to the plate thickness of the reinforcing plate 72 is formed in advance at the position where the reinforcing plate 72 is to be provided in the wooden frame molding parts 13A, 14A of the vertical frames 13, 14. Then, as shown in Figures 15 to 17, the reinforcing plate 72 is disposed in the recess 73 to cover and hide the wooden frame molding parts 13A, 14A of the part corresponding to the metal frame molding part 12B of the bottom frame 12, and the surface of the reinforcing plate 72 is disposed on the same plane as the metal frame molding parts 13B, 14B of the vertical frames 13, 14. The position of the reinforcing plate 72 is the same as in the embodiment. In this modification, the metal frame molding part 12B of the lower frame 12 or the reinforcing plate 72 is interposed between the metal frame molding part 12B of the lower frame 12 and the vertical frames 13, 14. Therefore, even if the screw member is screwed tightly, the metal frame molding part 12B of the lower frame 12 will not bite into the wood frame molding parts 13A, 14A of the vertical frames 13, 14, and there is no risk of impairing the watertightness between them.

Also, the first molded part is exemplified as being molded from wood or the like, and the second molded part and the third molded part are exemplified as being molded from metal, but the present invention is not limited to these combinations. For example, the first molded part may be molded from resin, and the second molded part may be molded from metal.

[0026] In the above-mentioned embodiment, the vertical frame is provided with a metal frame molding part, but the vertical frame may be formed only with a wood frame molding part. Similarly, the horizontal member is provided with a wood frame molding part, but the horizontal member may be formed only with a metal frame molding part.

[0027] As described above, the building fixture of the present invention comprises vertical members and horizontal members, the vertical members having a first molded portion, the horizontal members having a second molded portion having a harderness than the first molded portion, and the horizontal members are connected via the end face to the projected surface that is on the inner periphery of the vertical members at a position where the first molded portion and the second molded portion correspond to each other, and is characterized in that a reinforcing plate having a harderness than the first molded portion is interposed between the first molded portion and the second molded portion.

[0028] According to this invention, a reinforcing plate having a harder hardness than the first molded portion is interposed between the first molded portion of the vertical member and the second molded portion of the horizontal member, so that even when a screw member is screwed into the vertical member and the horizontal member, there is no risk of the horizontal member being deformed, such as by being bitten into the vertical member.

[0029] The present invention is also characterized in that, in the above-mentioned building fixture, a third molded portion having a harderness than the first molded portion is exposed on the projected surface on the inner periphery of the vertical member, the second molded portion of the horizontal member has portions corresponding to the first molded portion and the third molded portion, and the reinforcing plate is arranged so as to be continuous across the second molded portion and the corresponding portions of the first molded portion and the third molded portion.

[0030] According to this invention, since the reinforcing plate is provided continuously from the first molded portion to the third molded portion, it is advantageous in terms of strength even when the vertical member is handled alone.

[0031] The present invention is also characterized in that, in the above-mentioned building fixture, a third molded portion having a harderness than the first molded portion is exposed on the projected surface on the inner periphery of the vertical member, the second molded portion of the horizontal member has portions corresponding to the first molded portion and the third molded portion, and the reinforcing plate is interposed only in the portions corresponding to the second molded portion and the first molded portion.

[0032] According to this invention, it is possible to prevent the horizontal members from biting into the vertical members by using a minimum number of reinforcing plates.

[0033] Furthermore, the present invention is characterized in that, in the above-mentioned fitting, the reinforcing plate and the second molded portion are molded from the same material.

[0034] According to this invention, there is no risk of the second molded portion getting caught in the reinforcing plate.

[0035] Furthermore, the present invention is characterized in that, in the above-mentioned fitting, the second molded portion and the third molded portion are molded from the same material.

[0036] According to this invention, there is no risk of the second molded portion getting caught in the third molded portion.
