[0004] In the above-mentioned fittings, the interior panel on the indoor side is openable and closable, and the exterior panel on the outdoor side is openable and closable. Therefore, by opening both panels, it is possible to naturally ventilate the room. However, the exterior panel can only be opened when the interior panel is open, and it is also located far from the room, so this is not necessarily preferable from the viewpoint of operability.

[0005] In view of the above-mentioned circumstances, the present invention has an object to provide a fitting that can improve operability. [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 an inner surface material is provided on the inner periphery of an opening frame formed by an upper building material, a lower building material, and left and right side building materials, and an outer surface material is provided at a position on the outside of the interior surface material within the range of the expected surface on the inner periphery of the opening frame, and the outer surface material is supported by the opening frame in a state in which a ventilation passage is secured between the outer surface material and the side building materials. A protrusion is provided toward the inner circumference on the inner peripheral side of the side building material, and the protrusion is provided so as to be continuous along the top and bottom, the outer surface material has a size that covers the protrusion, and a plurality of connecting members are provided between the protrusion and the outer surface material at intervals, and the ventilation passage is formed along the viewing direction between the plurality of connecting members in the mutually opposing portions of the protrusion and the outer surface material. It is characterized by the fact that Effect of the Invention

[0007] According to the present invention, since a ventilation passage is secured between the exterior panel placed on the outdoor side and the side building material, it is possible to circulate air without opening or closing the exterior panel. Therefore, by opening the interior panel or providing a ventilation passage in the interior panel, it is possible to naturally ventilate the room without operating the exterior panel in any way.

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" will 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 perpendicular to the visible direction in the case of a lower frame or the like that extends horizontally. In the case of a vertical frame or the like that extends vertically, 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] (Embodiment 1) 1 to 5 show a fitting according to a first embodiment of the present invention. The fitting exemplified here is applied to the exterior wall of a building or other structure. The building according to the first embodiment has an exterior wall formed of a rectangular panel 1 made of reinforced concrete, and is provided with a fitting in a rectangular opening in the exterior wall. The fitting is attached at a height that will become the interior space of the building, and is composed of a frame body (opening frame) 10, an inner surface material 20 arranged on the inner periphery of the frame body 10, a blind device 30, and an outer surface material 40. The frame body 10 is composed of an upper frame (upper building material) 11, a lower frame (lower building material) 12, and left and right vertical frames (side building materials) 13 framed on all four sides. The upper frame 11, the lower frame 12, and the left and right vertical frames 13 are extruded shapes formed from a metal such as an aluminum alloy, and are configured to have a substantially uniform cross section along the entire length along the longitudinal direction.

[0011] As shown in FIG. 6, the upper frame 11 is formed by integrally forming an inner upper frame portion 11a arranged on the indoor side and an outer upper frame portion 11b arranged on the outdoor side. The inner upper frame portion 11a has a rectangular cross section. The inner upper frame portion 11a is provided with an upper door stop piece 11c, two upper lock pin receiving pieces 11d, and two upper anchor engagement pieces 11e. The upper door stop piece 11c extends almost vertically from the corner on the outdoor side toward the indoor side on the projected surface that is the inner periphery of the inner upper frame portion 11a, and has a seal mounting groove 11c1 on the part of the extended edge that faces the indoor side. The two upper lock pin receiving pieces 11d extend toward the indoor side from the middle part on the projected surface that is the inner periphery of the inner upper frame portion 11a, and the extended edges are bent in a direction approaching each other. A gap is provided between the bent portions of the two upper lock pin receiving pieces 11d. The upper anchor engaging pieces 11e extend from the corners facing the outside and inside of the interior frame portion 11a on the projected surface facing the outside of the interior frame portion 11a toward the outside, and then bend in such a direction that they approach each other.

[0012] The outer upper frame portion 11b has a cylindrical shape with a cross section of a nearly right-angled triangle. More specifically, the outer upper frame portion 11b has a projection portion 11b1 extending almost horizontally from the corner on the outer side of the room toward the outside on the projection surface of the inner upper frame portion 11a, a visible portion 11b2 extending almost vertically from the outer peripheral end of the upper anchor engaging piece 11e on the outer side toward the outer peripheral side, and a hypotenuse portion 11b3 inclined gradually toward the inner peripheral side toward the outside of the room so as to connect between the projection portion 11b1 and the visible portion 11b2. The dimension of the outer upper frame portion 11b along the projection direction is set to be nearly twice the dimension of the inner upper frame portion 11a along the projection direction. A waterproof material 14 made of an elastic material is provided on the projection surface of the outer upper frame portion 11b that is the inner peripheral side. The water-stopping material 14 has a drip-water piece 14b extending vertically downward from the edge of the mounting piece 14a located on the outside of the room, and is arranged over the entire length of the part of the upper frame 11 between the vertical frames 13.

[0013] As shown in Figures 7 and 8, the lower frame 12 is formed by integrally forming an inner lower frame portion 12a arranged on the indoor side and an outer lower frame portion 12b arranged on the outdoor side. The inner lower frame portion 12a is tubular with a rectangular cross section, and is configured so that the dimensions along the projection direction are almost the same as those of the inner upper frame portion 11a. This inner lower frame portion 12a is provided with a lower door stop piece 12c, two lower lock pin receiving pieces 12d, and two lower anchor engagement pieces 12e. The lower door stop piece 12c extends almost vertically from the corner on the outdoor side to the inner side on the projection surface that is the inner peripheral side of the inner lower frame portion 12a, and has a seal mounting groove 12c1 on the part of the extended edge that faces the indoor side. The two lower lock pin receiving pieces 12d each extend from the middle of the inner peripheral surface of the inner lower frame portion 12a toward the inner peripheral side, and the extending edges are bent in a direction approaching each other. A gap is provided between the bent portions of the two lower lock pin receiving pieces 12d. The lower anchor engaging pieces 12e each extend from the outer peripheral corner and the inner peripheral corner of the outer peripheral surface of the inner lower frame portion 12a toward the outer peripheral side, and then are bent in a direction approaching each other.

[0014] The outer lower frame portion 12b has a cylindrical shape with a cross section that is approximately trapezoidal. More specifically, the outer lower frame portion 12b has a trapezoidal shape having an oblique side portion 12b1 that is inclined from the approximately middle part of the visible surface of the inner lower frame portion 12a facing the outside of the room to gradually become the outer periphery side toward the outside of the room, a lower base portion 12b2 that extends approximately vertically from the outer periphery end of the lower anchor engaging piece 12e on the outside of the room toward the outer periphery side, an upper base portion 12b3 that extends approximately vertically from the extending edge of the oblique side portion 12b1 toward the outer periphery, and a projection portion 12b4 that extends approximately horizontally in the direction connecting the upper base portion 12b3 and the lower base portion 12b2. The dimension of the outer lower frame portion 12b along the projection direction is set to be approximately twice the dimension of the inner lower frame portion 12a along the projection direction.

[0015] The left and right vertical frames 13 are symmetrical to each other, and as shown in Fig. 9, each has a flat vertical frame base 13a. The vertical frame base 13a is formed so that the dimension along the projection direction is almost the same as the dimension along the projection direction of the upper frame 11, and extends up and down along the projection direction. This vertical frame base 13a is provided with a side door stop piece 13b, two side lock pin receiving pieces 13c, and two side anchor engagement pieces 13d on the part that faces the room side. The side door stop piece 13b extends almost vertically from the projection position corresponding to the upper door stop piece 11c of the upper frame 11 on the projection surface that is the inner circumference side of the vertical frame base 13a toward the inner circumference side, and has a seal mounting groove 13b1 on the part of the extended edge that faces the room. The two side lock pin receiving pieces 13c each extend inward from a projected position corresponding to the upper lock pin receiving piece 11d of the upper frame 11 on the projected surface on the inner periphery of the vertical frame base 13a, and the extended edges are bent in a direction approaching each other. A gap is secured between the bent portions of the two side lock pin receiving pieces 13c. The side anchor engaging pieces 13d each extend outward from an edge portion on the inside of the room on the projected surface on the outer periphery of the vertical frame base 13a and a portion slightly outside the room than the side door stop piece 13b, and then bend in a direction approaching each other.

[0016] The upper frame 11, lower frame 12 and left and right vertical frames 13 having the above-mentioned configuration form a frame body 10 by connecting the upper frame 11 between the upper ends of the left and right vertical frames 13 and connecting the lower frame 12 between the lower ends of the left and right vertical frames 13, as shown in Figures 2 to 4, and each is fixed to the panel 1.

[0017] The interior panel 20 is composed of two uprights 21 arranged in the interior side of the frame 10, a main panel part 210, and two sleeve panel parts 220. The uprights 21 are arranged parallel to the vertical frames 13, and divide the interior of the frame 10 into three parts, left and right. In the illustrated example, the uprights 21 are arranged at equal distances from the vertical frames 13 and at positions where the distance between the uprights 21 is greater than the distance between the uprights 21 and the vertical frames 13 (positions where the distance is six times or more in the illustrated example). The uprights 21 are extruded shapes formed from a metal such as an aluminum alloy, and are configured to have a substantially uniform cross section along the entire length along the longitudinal direction. In the present embodiment 1, as shown in FIG. 10, a upright 21 having a square tubular upright base 21a is exemplified. The upright base 21a is configured so that its dimension along the front direction is approximately the same as that of the inner upper frame part 11a of the upper frame 11, and has a mullion door stop piece 21b and two mullion lock pin receiving pieces 21c on each of the front faces on both sides. The mullion door stop piece 21b extends so as to protrude from the corner on the outside of the room on the front face of the upright base 21a, and has a seal mounting groove 21b1 on the part of the extended edge facing the room. A sleeve window seal member 16 is attached to the seal mounting groove 21b1 of the mullion door stop piece 21b adjacent to the vertical frame 13 so as to be continuous with the seal mounting groove 13b1 of the vertical frame 13, the seal mounting groove 11c1 of the upper frame 11, and the seal mounting groove 12c1 of the lower frame 12. A main window seal member 17 is attached to the seal mounting groove 21b1 of the mullion door stop piece 21b separated from the vertical frame 13 so as to be continuous with the seal mounting groove 11c1 of the upper frame 11 and the seal mounting groove 12c1 of the lower frame 12. The two mullion lock pin receiving pieces 21c extend so as to protrude from projected positions corresponding to the upper lock pin receiving piece 11d of the upper frame 11 on the projected surface of the mullion base 21a, and the extended edges are bent in directions approaching each other. A gap is secured between the bent portions of the two mullion lock pin receiving pieces 21c.

[0018] As shown in Figs. 2 to 4, the main surface material part 210 is constructed by attaching inner frame materials, that is, an inner main upper frame 212, an inner main lower frame 213, and left and right inner main vertical frames 214, to the four periphery of a rectangular insulating glass 211. The main surface material part 210 of the present embodiment 1 constitutes a so-called inward-opening window between the frame body 10 and the mullion 21, and is provided with a hinge 215 between the inner main vertical frame 214 on the right side as viewed from the inside of the room and the adjacent mullion 21, and can be opened to the inside of the room around the axis of the hinge 215 along the top and bottom. When the main surface material part 210 is closed, the inner main upper frame 212, the inner main lower frame 213, and the left and right inner main vertical frames 214 are simultaneously in contact with the main window seal member 17, and the opening between the mullions 21 can be closed.

[0019] The two sleeve panel parts 220 are each constructed by attaching inner frame materials, an inner sleeve upper frame 222, an inner sleeve lower frame 223, and left and right inner sleeve vertical frames 224, around the four periphery of a rectangular insulating glass 221. The sleeve panel part 220 in this embodiment 1 constitutes a so-called vertical sliding window between the frame body 10 and the upright 21, and is provided with link mechanisms (not shown) between the inner sleeve upper frame 222 and the upper frame 11, and between the inner sleeve lower frame 223 and the lower frame 12, so that the inner sleeve vertical frame 224 adjacent to the upright 21 becomes the door end and can be opened to protrude into the room. When each sleeve panel part 220 is closed, the inner sleeve upper frame 222, the inner sleeve lower frame 223, and the left and right inner sleeve vertical frames 224 are simultaneously in contact with the sleeve window seal member 16, making it possible to close the opening between the upright 21 and the vertical frame 13. The inner main upper frame 212, the inner main lower frame 213, and the inner main vertical frame 214 constituting the main panel part 210, and the inner sleeve upper frame 222, the inner sleeve lower frame 223, and the inner sleeve vertical frame 224 constituting the sleeve panel part 220 are extruded shapes formed from metal such as aluminum alloy, and are configured to have a substantially uniform cross section over the entire length along the longitudinal direction. In the illustrated example, the inner sleeve upper frame 222, the inner sleeve lower frame 223, and the inner sleeve vertical frame 224 have the same cross-sectional shape.

[0020] Although not shown in the figure, the main panel portion 210 and the sleeve panel portion 220 are provided with a locking device using a lock pin between the frame body 10 and the upright 21. That is, the main panel portion 210 and the sleeve panel portion 220 are provided with a lock pin movably arranged on the outer periphery, and in the closed state, the lock pin is engaged with the lock pin receiving member 18 of the frame body 10 and the lock pin receiving member 18 of the upright 21 to prevent movement in the opening direction. The lock pin receiving member 18 is fixed to the lock pin receiving pieces 11d, 12d, 13c, 21c of the frame body 10 and the upright 21. Here, the lock pin receiving pieces 11d, 12d, 13c, 21c are provided in pairs at positions with a gap between them, and the extended edges are bent in a direction approaching each other. Therefore, when fixing the lock pin receiving member 18, the back plate 18a can be inserted through the gap between the lock pin receiving pieces 11d, 12d, 13c, and 21c, facilitating the work of fixing the lock pin receiving member 18 to the lock pin receiving pieces 11d, 12d, 13c, and 21c.

[0021] The blind device 30 is configured with multiple slats 33 between a head box 31 and a bottom rail 32, and is suspended and held via the head box 31 on the indoor side of the prospective surface that is the inner periphery of the outer upper frame portion 11b. This blind device 30 has a dimension that spans the distance between the vertical frames 13, and by appropriately operating the operating cord 34, the bottom rail 32 can be moved up and down, and when moved to the lowest position, it is possible to cover the entire surface of the inner panel material 20 that faces outside.

[0022] A shielding member 35 is provided in a portion facing the bottom rail 32 of the blind device 30 between the lower ends of the vertical frames 13. The shielding member 35 is an extruded member formed from a metal such as an aluminum alloy, and is configured to have a substantially uniform cross section over the entire length along the longitudinal direction. In the present embodiment 1, as shown in FIG. 7, a shielding member 35 having a blind receiving portion 35a and a shield plate portion 35b is applied. The blind receiving portion 35a is abutted against the bottom rail 32 mainly when the bottom rail 32 is disposed at the lowest position, and has a flat base wall portion 35a1 and a restricting wall portion 35a2 protruding upward from a portion of the base wall portion 35a1 located on the outside of the room from the bottom rail 32 and a portion of the base wall portion 35a1 located on the inside of the room from the bottom rail 32. The base wall portion 35a1 is a portion on which the bottom rail 32 is placed when the blind device 30 is pulled out to the lowest position. The distance between the restricting walls 35a2 is greater than the width of the bottom rail 32 so that the bottom rail 32 can be easily accommodated. The shield plate 35b extends downward from the lower edge of the restricting wall 35a2 provided on the indoor side, then curves and extends at an angle gradually downward toward the outdoor side. The dimension along the longitudinal direction of the shield plate 35b is shorter than the blind receiving portion 35a and is approximately equal to the distance between the attachments 53 described later. The extended edge of the shield plate 35b abuts against the visible surface facing the indoor side of the outer lower frame 43 of the outer surface material 40 described later.

[0023] As shown in Figs. 1 to 4, the exterior surface material 40 is constructed by attaching exterior frame materials, an exterior upper frame 42, an exterior lower frame 43, and left and right exterior vertical frames 44, to the four periphery of a rectangular laminated glass 41, and is disposed on the outdoor side of the frame body 10. The exterior surface material 40 of this embodiment 1 is disposed within the range of the prospective surface on the inner periphery side of the frame body 10, and the visible surface facing the outdoor side is located inside the room side of the visible surface of the frame body 10 facing the outdoor side. In other words, the exterior surface material 40 is disposed so as to be located outside the portion of the frame body 10 where the interior surface material 20 is provided, that is, within the range surrounded by the exterior upper frame portion 11b, the exterior lower frame portion 12b, and the portion of the vertical frame 13 that is outside the room side of the side door stop piece 13b. The outer dimensions of the outer panel 40 are set so that the vertical dimension is larger than that of the main panel portion 210 of the inner panel 20, and the horizontal dimension is approximately equal to the distance between the inner sleeve vertical frames 224 located on the outer periphery side of the two sleeve panel portions 220. When the outer panel 40 is placed on the inner periphery side of the frame body 10, it is possible to secure gaps between the upper frame 11, the lower frame 12, and the left and right vertical frames 13 of the frame body 10. The outer upper frame 42, the outer lower frame 43, and the outer vertical frame 44 that constitute the outer panel 40 are extruded shapes formed from metal such as aluminum alloy, and are configured to have a substantially uniform cross section over the entire length along the longitudinal direction. In the illustrated example, the outer upper frame 42, the outer lower frame 43, and the outer vertical frame 44 have the same cross-sectional shape.

[0024] In this outer panel 40, one hook member (connecting member) 45 is provided on each of the outer upper frame 42 and the outer lower frame 43, and three hook members 45 are provided at intervals on each of the left and right outer vertical frames 44. As shown in Fig. 11, the hook member 45 is integrally formed with a flat fixing plate portion 45a, a top plate portion 45b that extends from the upper edge of the fixing plate portion 45a toward the interior of the room, and a locking plate portion 45c that extends downward from the extended edge of the top plate portion 45b, bending at a substantially right angle. Each hook member 45 is fixed to the visible surface of the outer frame members 42, 43, 44 facing the interior of the room by placing a back plate 46 on the outer frame members 42, 43, 44 and screwing a screw 47 into the back plate 46 via the fixing plate portion 45a. 12, a positioning hole 45d is additionally machined in the top plate portion 45b of the hook member 45 provided on the outer lower frame 43. The positioning hole 45d is a through hole with a circular cross section formed in a portion that is approximately in the center of the top plate portion 45b in the left-right dimension.

[0025] The outer panel material 40 having the above-mentioned configuration is supported by the frame body 10 with gaps secured between the upper frame 11, the lower frame 12 and the left and right vertical frames 13, by engaging the hook members 45 provided on each of the outer frame members 42, 43, 44 with hook receiving members (connecting members) 50, 51 provided on the frame body 10.

[0026] The hook receiving member 50 provided on the upper frame 11 and the vertical frame 13 is integrally formed with a flat receiving fixed plate portion 50a, a bottom plate portion 50b that extends from the lower edge of the receiving fixed plate portion 50a toward the outside of the room at a substantially right angle, and a receiving plate portion 50c that extends from the extended edge of the bottom plate portion 50b at a substantially right angle toward the upper side. The plate thickness of the receiving plate portion 50c is set to be substantially equal to the mutual distance between the fixing plate portion 45a and the locking plate portion 45c in the hook member 45. One hook receiving member 50 of the upper frame 11 is fixed to the substantially central part of the projected surface on the inner periphery side of the upper frame 11 via an upper bracket 52, and three hook receiving members 50 of the vertical frame 13 are fixed to the projected surface on the inner periphery side of the vertical frame 13 via an attachment (protruding portion) 53.

[0027] 6, the upper bracket 52 has a frame mounting plate portion 52a attached to the visible surface of the upper frame 11 and a receiving mounting plate portion 52b connected to the receiving fixed plate portion 50a of the hook member 45, and is attached to the upper frame 11 with the receiving mounting plate portion 52b located on the exterior side of the head box 31 of the blind device 30. The hook receiving member 50 attached to the upper frame 11 via the upper bracket 52 is set so that when the top plate portion 45b of the hook member 45 provided on the outer stile 42 is abutted against the upper surface of the receiving plate portion 50c, the outer stile 42 is located on the outer side of the inner peripheral position of the upper door stop piece 11c of the upper frame 11, and the outer stile 43 is located on the outer side of the inner peripheral position of the lower door stop piece 12c of the stile 12.

[0028] As shown in FIG. 9, the attachment 53 has a cross section of a substantially rectangular cylinder, and is attached to the entire length between the upper frame 11 and the lower frame 12 on the inner peripheral side of the vertical frame 13. The projection dimension of the attachment 53 from the inner peripheral side of the vertical frame 13 is set to be larger than the projection dimension of the side door stop piece 13b provided on the vertical frame 13, and smaller than the inner peripheral position of the inner sleeve vertical frame 224 located on the outer peripheral side of the sleeve surface material part 220. In this embodiment 1, the inner peripheral position of the attachment 53 is configured to almost coincide with the inner peripheral position of the outer vertical frame 44. The attachment 53 has a mounting groove 53a in a portion facing the room. The mounting groove 53a is a dovetail groove with an inner width larger than the width of the opening, and the width of the opening is formed to a dimension that allows the hook receiving member 50 to be fitted. The above-mentioned hook receiving member 50 is fixed to the attachment 53 by inserting the receiving side fixing plate portion 50a into the mounting groove 53a, disposing the back plate 54 in the hollow portion of the attachment 53, and screwing the screws 55 into the back plate 54 through the receiving side fixing plate portion 50a. In the present embodiment 1, the hook receiving members 50 are provided in three places on the upper end, middle portion, and lower end of the attachment 53 in correspondence with the hook members 45 provided on the outer vertical frame 44 of the outer panel member 40.

[0029] On the other hand, the hook receiving member 51 provided on the lower frame 12 has a flat lower plate portion 51a extending almost horizontally along the projection direction, and a flat vertical plate portion 51b extending almost vertically upward from the edge of the lower plate portion 51a on the outside of the room. The plate thickness of the vertical plate portion 51b is set to be almost equal to the mutual distance between the fixing plate portion 45a and the locking plate portion 45c in the hook member 45. This hook receiving member 51 is fixed to a portion that is almost the center with an oblique spacer 56 interposed between the lower plate portion 51a and the projection surface on the inner periphery side of the lower frame 12. A positioning protrusion 51c is provided at the center of the upper end surface of the vertical plate portion 51b. The positioning protrusion 51c is configured to fit into the positioning hole 45d of the hook member 45 provided on the outer lower frame 43 when the outer panel 40 is positioned at a position that is approximately central with respect to the projected surface on the inner periphery of the frame body 10.

[0030] To support the exterior surface material 40 on the frame body 10 provided with the above-mentioned hook receiving members 50, 51, the exterior surface material 40 is inserted from the outside of the room with the locking plate portion 45c of the hook member 45 positioned above the receiving plate portion 50c and the vertical plate portion 51b of the hook receiving members 50, 51. Thereafter, the fixed plate portion 45a of the hook member 45 is brought into contact with the receiving plate portion 50c and the vertical plate portion 51b of the hook receiving members 50, 51, and the exterior surface material 40 is moved downward in this state, whereby the receiving plate portion 50c and the vertical plate portion 51b of the hook receiving members 50, 51 are fitted between the fixed plate portion 45a of the hook member 45 and the locking plate portion 45c, and the receiving plate portion 50c and the vertical plate portion 51b of the hook receiving members 50, 51 are brought into contact with the top plate portion 45b of the hook member 45. At this time, the positioning projection 51c of the hook receiving member 51 fits into the positioning hole 45d of the hook member 45 provided in the lower frame 12, thereby determining the position of the outer panel member 40 relative to the frame body 10 in the left-right direction.

[0031] In this state, the hook member 45 and the hook receiving members 50, 51 engage with each other, thereby preventing the exterior panel 40 from moving in the projection direction and downward relative to the frame body 10. Furthermore, in the fitting of the first embodiment, as shown in Fig. 6, a lock screw 57 is screwed from the outside of the room into the receiving side fixed plate portion 50a of the hook receiving member 50 provided on the upper frame 11, thereby preventing the exterior panel 40 from moving upward relative to the frame body 10. That is, the lock screw 57 is a so-called hexagonal socket head screw, and is screwed into the hook receiving member 50 with its cylindrical head portion 57a ​​adjacent to the top plate portion 45b of the hook member 45 provided on the outer upper frame 42. As a result, the top plate portion 45b of the hook member 45 abuts against the head of the lock screw 57, preventing the outer panel 40 from moving upward relative to the frame body 10, and all of the hook members 45 are prevented from escaping from the hook receiving members 50, 51.

[0032] With the outer surface material 40 supported on the frame body 10 as described above, the water dripping piece portion 14b of the water stop material 14 provided on the upper frame 11 is pressed against the visible surface located on the outer periphery side of the outer upper frame 42. Therefore, there is no risk of rainwater or other water that has flowed down the upper panel 1 entering the room through the outer surface material 40. In addition, the shielding member 35 provided on the lower part of the frame body 10 is in a state where the extended edge portion of the shield plate portion 35b is abutted against the visible surface of the outer lower frame 43 facing the room. Therefore, between the outer lower frame 43 of the outer surface material 40 and the shielding member 35, vertical ventilation is blocked.

[0033] On the other hand, there is always a gap between the vertical frame 13 of the frame body 10 and the outer vertical frame 44 of the outer panel 40, and between the lower frame 12 and the outer lower frame 43. Therefore, if the main panel part 210 or the sleeve panel part 220 of the inner panel 20 is opened, it is possible to naturally ventilate the room without performing any operation on the outer panel 40. Moreover, the surface expected to be the outer periphery of the outer lower frame 43 is located on the outer periphery side of the inner periphery position of the lower door stop piece 12c, and the attachment 53 is located on the indoor side of the gap between the vertical frame 13 and the outer vertical frame 44. In other words, the ventilation passage leading to the inner panel 20 via the outer panel 40 is once bent toward the inner periphery as shown by the arrow B in Figures 7 and 9. Therefore, water will not reach the inner panel 20 directly through the gap between the outer panel 40 and the frame body 10, and there is no risk of outside water such as rainwater seeping into the room.

[0034] Here, as described above, between the outer lower frame 43 of the outer surface material 40 and the shielding member 35, vertical ventilation is blocked. Therefore, even when natural ventilation is performed with the blind device 30 lowered, the air that passes through the outer surface material 40 through the air inlet B1 between the outer lower frame 43 and the lower frame 12 does not pass through the slats 33 of the blind device 30 and reach the indoor side. This makes it possible to obtain stable light blocking without causing the slats 33 of the blind device 30 to swing even when the room is naturally ventilated. In addition, the air that passes through the outer surface material 40 through the air inlet B1 is guided to the indoor side by the shielding member 35, and then flows upward between the blind device 30 and the inner surface material 20. As a result, for example, even when the blind device 30 is heated by solar radiation, the air passing between the blind device 30 and the inner surface material 20 prevents the radiant heat from the blind device 30 from reaching the indoor side, and the heat blocking performance can be improved. Furthermore, in the above-mentioned fittings, laminated glass 41 is used as the exterior surface material 40. Therefore, even if flying objects collide during a storm such as a typhoon, it is possible to prevent the flying objects from penetrating the exterior surface material 40 and reaching the interior side of the room.

[0035] (Embodiment 2) 13 to 17 show fittings according to a second embodiment of the present invention. The fittings exemplified here are applied to the exterior walls of structures such as buildings, similar to the first embodiment, but differ from the first embodiment in the mullions 21, sleeve panel parts 220, water-stopping materials 14, blind devices 30, shielding members 35, and exterior panel materials 40. Below, differences from the first embodiment will be described in detail, and the same reference numerals will be used to designate the same components as those in the first embodiment, and detailed description thereof will be omitted.

[0036] The mullion (side building material) 321 of the second embodiment has a mullion base 21a, a mullion doorstop piece 21b, and two mullion lock pin receiving pieces 21c, as well as a panel support part 321d on the visible surface of the mullion base 21a facing the outside. The panel support part 321d protrudes from the mullion base 21a toward the outside, and has approximately the same dimensions along the visible direction as the mullion base 21a. An attachment part (protrusion) 321e is provided on the extended edge of the panel support part 321d. The attachment part 321e has a tubular shape with an approximately rectangular cross section, and protrudes in the direction in which the two mullions 321 approach each other. The position of the visible surface of the attachment part 321e facing the outside is approximately the same as the visible surface of the attachment 53 shown in the first embodiment facing the outside. The projection dimension of the attachment part 321e from the panel support part 321d is set to be smaller than the projection dimension of the mullion door stop piece 21b provided on the mullion 321. The attachment part 321e is provided with hook receiving members 50 at three locations, the upper end, the middle part and the lower end, via mounting grooves 53a on the part facing the room.

[0037] The sleeve panel part 230 is made of a metal such as an aluminum alloy and has a box-like shape with a nearly rectangular exterior, and has a contact fin part 231 on the outer peripheral surface. The contact fin part 231 extends from the interior side of the interior surface of the sleeve panel part 230 toward the outer periphery, and a sleeve window inner seal member 232 is attached to the part of the extended edge that faces the outside. The sleeve window inner seal member 232 is continuous around the four sides of the sleeve panel part 230, and when the sleeve panel part 230 is closed, it can be pressed against the lock pin receiving pieces 11d, 12d, 13c, 21c located on the interior side of the upper frame (upper building material) 11, the lower frame (lower building material) 12, the vertical frame 13, and the upright 321.

[0038] The water-stopping material 14, the blind device 30, the shielding member 35 and the outer panel 40 differ from those of the first embodiment only in the dimensions along the left-right direction so that they are provided between the left and right uprights 321, and the other configurations are the same as those of the first embodiment. Also, in the second embodiment, only the main panel portion 210 corresponds to the inner panel, so the reference numeral 20 is not used in the drawings.

[0039] In the fitting of the second embodiment configured as described above, the drip-off piece portion 14b of the water-stopping material 14 provided on the upper frame 11 is pressed against the projecting surface located on the outer periphery of the outer upper frame 42. Therefore, there is no risk of rainwater or other water that has flowed down the upper panel 1 penetrating into the room through the outer face material 40. Although the sleeve face material portion 230 is not covered by the outer face material 40, there is a sleeve window seal member 16 on the outside of the room and a sleeve window inner seal member 232 on the inside of the room, so there is no risk of rainwater or other water penetrating into the room.

[0040] On the other hand, there is always a gap between the upright 321 of the frame body 10 and the outer vertical frame 44 of the outer panel 40, and between the lower frame 12 and the outer bottom frame 43. Therefore, by opening the main panel part 210 of the inner panel 20, it is possible to naturally ventilate the room without performing any operation on the outer panel 40. Moreover, the surface that is expected to be the outer periphery of the outer bottom frame 43 is located on the outer periphery side of the inner periphery position of the lower door stop piece 12c, and the attachment part 321e is located on the indoor side of the gap between the upright 321 and the outer vertical frame 44. In other words, the ventilation passage leading to the inner panel 20 via the outer panel 40 is once bent toward the inner periphery as shown by the arrow B in Figures 7 and 18. Therefore, water does not reach the main surface material portion 210 of the inner surface material 20 directly through the gap between the outer surface material 40 and the lower frame 12 and the mullion 321, and there is no risk of outside water such as rainwater entering the room. Furthermore, the shielding member 35 provided at the lower part of the frame body 10 is in a state where the airtight material 35c provided at the shield plate portion 35b is pressed against the visible surface of the outer lower frame 43 facing the room. Therefore, even when natural ventilation is performed, air that has passed through the outer surface material 40 through the air inlet B1 does not advance upward through the gap between the outer lower frame 43 of the outer surface material 40 and the shielding member 35, and there is no risk of the slats 33 of the blind device 30 swinging. In addition, in the above-mentioned fitting, laminated glass 41 is used as the outer surface material 40. Therefore, even if flying objects collide during a typhoon or other strong wind, it is possible to prevent the flying objects from penetrating into the room. However, it is not necessary to use laminated glass 41 as the exterior panel 40. As for the sleeve panel portion 230, since it is made of metal and has a box-like structure as described above, there is also no risk of flying objects penetrating into the room.

[0041] In the above-mentioned first and second embodiments, the inner panel material is configured to be openable and closable, but this is not necessarily limited to the above, and the inner panel material may be provided with a ventilation passage. Furthermore, in the first embodiment, an inner panel material having a main panel portion and a sleeve panel portion is exemplified, and in the second embodiment, an inner panel material having only a main panel portion is exemplified, but the configuration of the inner panel material is not limited to these.

[0042] As described above, the building fixture of the present invention is a building fixture in which an inner panel is provided on the inner periphery of an opening frame formed by an upper building material, a lower building material, and left and right side building materials, and an outer panel is provided at a position that is outside the room relative to the inner panel within the range of the projected surface that is on the inner periphery of the opening frame, and the outer panel is supported by the opening frame with an air passage secured between it and the side building materials. According to this invention, since a ventilation passage is secured between the exterior panel placed on the outdoor side and the side building material, it is possible to circulate air without opening or closing the exterior panel. Therefore, by opening the interior panel or providing a ventilation passage in the interior panel, it is possible to naturally ventilate the room without operating the exterior panel in any way.

[0043] The present invention is also characterized in that in the above-mentioned fitting, a waterproofing material is provided between the outer surface material and the upper building material. According to this invention, it is possible to prevent water from entering from the outside through the gap between the outer panel material and the upper building material.

[0044] The present invention is also characterized in that, in the above-mentioned building fixture, a protrusion is provided toward the inner circumference on the inner periphery of the side building material, the outer panel material has a size sufficient to cover the protrusion, and the ventilation passage is provided along the visible direction in the opposing portions of the protrusion and the outer panel material. According to this invention, since the ventilation passage extends along the front direction, it is possible to suppress the intrusion of water through the ventilation passage.

[0045] The present invention is also characterized in that, in the above-mentioned building fixture, the protrusion is arranged in a continuous manner along the top and bottom, and a plurality of connecting members are provided at intervals between the protrusion and the outer panel material, and the ventilation passage is formed between the plurality of connecting members. According to this invention, there is no need to provide ventilation passages in the protrusions or the outer panel.

[0046] Furthermore, the present invention is characterized in that, in the above-mentioned fitting, the inner panel is arranged so as to be openable and closable relative to the opening frame. According to this invention, natural ventilation of the room can be achieved by opening the inner panel.

[0047] Furthermore, the present invention is characterized in that in the above-mentioned fitting, the outer panel material is constructed by attaching outer frame materials to all four peripheries of the laminated glass. According to this invention, because laminated glass is used as the outer panel, even if flying objects collide with the outer panel due to the influence of a storm, it is possible to prevent the objects from penetrating and causing damage to the inner panel. This prevents problems such as the storm directly entering the room.

[0048] The present invention is further characterized in that, in the above-mentioned fittings, the inner panel is constructed by attaching inner frame materials to the four sides of the glass, and the inner peripheral positions of the outer frame materials are configured to coincide with the inner peripheral position of the inner frame material or to be positioned outer than the inner peripheral position of the inner frame material. According to this invention, the outer frame material is difficult to see when viewed from inside the room, which is advantageous in terms of appearance quality. [Explanation of symbols]
