Description

[Technical Field]

[0001] The present invention relates to a fitting having exterior components such as a screen door or lattice on the part of the frame facing the outside of the room. [Background technology]

[0002] For example, some fittings with ventilation windows in door panels are equipped with exterior components such as screen doors or lattices that are installed to cover the ventilation windows. The exterior components are configured by providing, for example, netting or horizontal bars to an exterior frame body that is made up of an upper frame member, a lower frame member, and left and right side frame members, and are attached to the frame body of the ventilation window, which serves as the face material, via the exterior frame body (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Publication No. 7-305571 Summary of the Invention [Problem to be solved by the invention]

[0004] In building fixtures equipped with exterior components, water such as rainwater poured onto the facing may seep between the exterior component and the facing. The lower frame of the exterior frame extends almost horizontally along its length. This makes it difficult for water that seeps between the exterior component and the facing to be discharged to the outside, and there is a concern that the lower frame will act as a dam and cause the water to remain trapped. In particular, it becomes even more difficult to discharge water that has turned into granules. Note that the above-mentioned problem is not necessarily limited to those with exterior components attached to the facing, but can also occur in those with exterior components attached to a frame attached to the main body.

[0005] In view of the above-mentioned circumstances, the present invention aims to improve the drainage performance of fittings equipped with exterior members. [Means for solving the problem]

[0006] In order to achieve the above-mentioned object, the fitting of the present invention is a fitting that has an exterior member on the part of the frame body that faces outside the room, and the exterior member is attached to the frame body via an exterior frame body, and the lower frame material that forms the lower edge of the exterior frame body has a gutter section that runs along the length between it and the frame body, and the inner bottom surface of the gutter has a water guide groove that extends along the length and is continuous with a drain outlet to the outside. [Effects of the Invention]

[0007] According to the present invention, water that has seeped in between the exterior member and the frame is collected in the gutter and is then drained to the outside through the gutter. Moreover, since the gutter has a water guide groove on the inner bottom surface, it is possible to prevent the water that has collected in the gutter from forming granules and stagnating, thereby improving the drainage of the fittings equipped with the exterior member. [Brief explanation of the drawings]

DETAILED DESCRIPTION OF THE INVENTION

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

[0010] 1 to 4 show a fitting according to an embodiment of the present invention. The fitting illustrated here is used as a back door and includes an opening frame 1 and a door panel 2. The opening frame 1 is formed by a framework consisting of an upper frame 1A, a lower frame 1B, and left and right vertical frames 1C, and supports the door panel 2 via hinges 3 so that it can be opened and closed. The upper frame 1A, lower frame 1B, and left and right vertical frames 1C that make up the opening frame 1 are all extruded shapes formed from metal such as aluminum alloy, and each is configured so that its entire longitudinal length has a substantially uniform cross-sectional shape. Resin frame cover members 1Aa, 1Ba, and 1Ca are attached to the portions of the upper frame 1A, lower frame 1B, and left and right vertical frames 1C that are exposed to the interior of the room, respectively. The door panel 2 is configured with a door frame body (frame body) 10 and two shoji screens 20A and 20B. Below, the configuration of the door panel 2 will be described in detail, along with the characteristics of the present invention. For the sake of convenience, the posture of each component will be specified below with the door panel 2 supported by the opening frame 1.

[0011] The door frame 10 is formed by framing an upper door frame 11, a lower door frame 12, and left and right vertical door frames 13, 14 on all four sides. The upper door frame 11, the lower door frame 12, and the vertical door frames 13, 14 are all composite types comprising metal elements molded from metal such as aluminum alloy and resin elements molded from resin, and are supported by the opening frame 1 with the metal elements facing the exterior. The metal elements and the resin elements are all extruded shapes, and each is configured so that the entire longitudinal length has a substantially uniform cross-sectional shape.

[0012] The metal-molded element 11A of the upper door frame 11 is formed by integrally molding an upper door frame base 11Aa and an upper door support wall 11Ab. The upper door frame base 11Aa is hollow and has a vertically elongated, approximately rectangular cross section. A resin-molded element 11B is attached to the upper door frame base 11Aa so as to cover almost the entire surface facing the interior of the room. A resin-molded upper frame recess member 11C is provided on the inner peripheral surface of the upper door frame base 11Aa and the resin-molded element 11B so as to protrude toward the interior of the room. The upper door support wall 11Ab is a thin plate-like member that extends almost horizontally from the inner peripheral portion of the upper door frame base 11Aa's outer peripheral surface toward the outside, and then bends almost at a right angle toward the inner peripheral side.

[0013] The metal molded element 12A of the lower door frame 12 is integrally formed with a lower door frame base 12Aa, a lower door boundary wall 12Ab, a lower door inner peripheral wall 12Ac, and a lower door support wall (guide wall) 12Ad. Like the upper door frame base 11Aa, the lower door frame base 12Aa is hollow and has a vertically elongated, approximately rectangular cross section. The dimensions of the lower door frame base 12Aa along the front and rear directions are approximately the same as those of the upper door frame base 11Aa. A resin molded element 12B is attached to the lower door frame base 12Aa so as to cover almost the entire front surface facing the interior of the vehicle. The lower door boundary wall 12Ab is a thin plate-like member that protrudes inward from approximately the center of the front surface of the lower door frame base 12Aa, which is the inner peripheral side of the front surface. The lower door inner peripheral wall portion 12Ac protrudes inward from a corner on the interior side of the lower door frame base 12Aa, then bends toward the interior, and bends again toward the interior. A resin-molded lower frame cover member 12C is attached to the outer surface of the lower door inner peripheral wall portion 12Ac. The lower door support wall portion 12Ad is a thin plate-like member that extends gradually downward from an exterior corner on the inner peripheral side of the lower door frame base 12Aa toward the exterior. The protruding dimension of the lower door support wall portion 12Ad toward the exterior is approximately the same as the protruding dimension of the upper door support wall portion 11Ab toward the exterior.

[0014] The metal molded element 13A of the vertical door frame 13 on the hanging side has a hanging outer peripheral portion 13AA and a hanging inner peripheral portion 13AB that are molded separately from each other. The hanging outer peripheral portion 13AA is hollow with a horizontally elongated, approximately rectangular cross section. A resin molded element 13C is attached to this hanging outer peripheral portion 13AA so as to cover almost the entire visible surface facing the interior of the room. The hanging inner peripheral portion 13AB is integrally molded with a vertical door frame base 13ABa, a vertical door inner visible wall portion 13ABb, a vertical door outer visible wall portion 13ABc, and a vertical door boundary wall portion 13ABd. The vertical door frame base 13ABa is a flat plate extending approximately vertically along the projection direction. The vertical door inner sight wall 13ABb is a thin plate extending from the interior edge of the vertical door frame base 13ABa toward the inner periphery. The vertical door outer sight wall 13ABc is a flat plate extending from the exterior edge of the vertical door frame base 13ABa toward the inner periphery. The vertical door boundary wall 13ABd is a thin plate protruding toward the inner periphery at a portion of the inner projection surface of the vertical door frame base 13ABa that is approximately equidistant from the vertical door inner sight wall 13ABb and the vertical door outer sight wall 13ABc. A vertical frame inner periphery cover member 13D molded from resin is attached to the portion extending from the projection surface of the vertical door boundary wall 13ABd facing the interior of the room to the projection surface of the inner periphery of the vertical door frame base 13ABa. In addition, a vertical frame outer periphery cover member 13E molded from resin is attached to the portion extending from the visible surface of the vertical door inner sight wall portion 13ABb facing the interior of the room to the visible surface on the outer periphery side of the vertical door frame base portion 13ABa.

[0015] The metal molded element 14A of the vertical door frame 14 on the door leading side has a door leading outer peripheral portion 14AA and a door leading inner peripheral portion 14AB, which are molded separately from each other. The door leading outer peripheral portion 14AA is hollow with a horizontally elongated, approximately rectangular cross section and differs from the hanging base outer peripheral portion 13AA in that it has a cover fin portion 14AAb. That is, the door leading outer peripheral portion 14AA is integrally formed with a cover fin portion 14AAb that protrudes toward the outside from the outer corner on the outer periphery and then bends toward the outer periphery. A resin molded element 14C is attached to this door leading outer peripheral portion 14AA so as to cover almost the entire visible surface facing the room. The door-end inner peripheral portion 14AB, like the hanging-end inner peripheral portion 13AB, is formed by integrally molding a vertical door frame base 14ABa, a vertical door inner sight wall portion 14ABb, a vertical door outer sight wall portion 14ABc, and a vertical door boundary wall portion 14ABd. It is also similar to the hanging-end vertical door frames 13, 14 in that it is provided with a vertical frame inner peripheral cover member 14D and a vertical frame outer peripheral cover member 14E. Reference numeral 15 in the drawing denotes a door handle provided on the vertical door frame 14 on the door-end side.

[0016] The two shoji screens 20A, 20B are arranged so as to be movable up and down inside the door frame 10, respectively, in a portion on the interior side of the boundary walls 12Ab, 13ABd, 14ABd and a portion on the exterior side of the boundary walls 12Ab, 13ABd, 14ABd. The shoji screen on the interior side (hereinafter referred to as the inner shoji screen 20A when distinguishing between them) is constructed by attaching an upper frame 22A, a lower frame 23A, and left and right vertical frames 24A to the four periphery of a rectangular double-glazed glass 21A. The shoji screen on the exterior side (hereinafter referred to as the outer shoji screen 20B when distinguishing between them) is constructed by attaching an upper frame 22B, a lower frame 23B, and left and right vertical frames 24B to the four periphery of a rectangular double-glazed glass 21B. In this embodiment, the inner shoji 20A is positioned downward with the upper frame 22A of the inner shoji 20A and the lower frame 23B of the outer shoji 20B arranged side by side in the forward direction, and the dimensions of each shoji 20A, 20B are set so that when the outer shoji 20B is positioned upward, it can block the opening of the door frame 10. The upper frame 22A, lower frame 23A, and left and right vertical frames 24A of the inner shoji 20A and the upper frame 22B and left and right vertical frames 24B of the outer shoji 20B are all composite types equipped with metal molded elements formed from metal such as aluminum alloy and resin molded elements formed from resin, and hold the double-glazed glass 21A, 21B between them with the metal molded elements facing the outside. The lower frame 23B of the outer shoji 20B is integrally molded from metal such as aluminum alloy. The frames that make up these shoji screens 20A, 20B are not limited to metal or resin molded elements, but are all extruded shapes, and each is configured so that the entire length along the length has a nearly uniform cross-sectional shape. The symbol 25 in the figure is a crescent lock installed between the upper frame 22A of the inner shoji screen 20A and the lower frame 23B of the outer shoji screen 20B.

[0017] Furthermore, the door panel 2 is provided with a lattice screen (exterior member) 30 on its surface facing the outside. The lattice screen 30 is constructed by installing a net 32 and horizontal bars 33 inside a screen frame (exterior frame) 31. The screen frame 31 is constructed by framing an upper frame member 34A, a lower frame member 34B, and left and right side frame members 34C all around, and is sized to cover the opening of the door frame 10. Multiple horizontal bars 33 are installed between the side frame members 34C, approximately parallel to each other. The upper frame member 34A, the lower frame member 34B, the left and right side frame members 34C, and the horizontal bars 33 are extruded shapes formed from metal such as aluminum alloy, and each is configured so that the entire longitudinal length has an approximately uniform cross-sectional shape.

[0018] In this embodiment, the upper frame member 34A, the lower frame member 34B, and the left and right side frame members 34C have the same cross-sectional shape. That is, the upper frame member 34A, the lower frame member 34B, and the left and right side frame members 34C (hereinafter collectively referred to as frame member 34) each have a bottom wall portion 34a, an outer peripheral sight wall portion 34b, a surface wall portion 34c, an inner peripheral sight wall portion 34d, and an inner peripheral sight wall portion 34e integrally molded. The bottom wall portion 34a has a flat plate shape extending along the sight wall direction. As shown in FIG. 5 , the inner peripheral surface of the bottom wall portion 34a is formed with multiple water guide grooves 34f (two in the illustrated example). Each water guide groove 34f is identical to the others and has a constant width (a narrow width of 2 mm or less in this embodiment). It extends linearly along the length of the frame member 34 and opens at both end faces of the frame member 34. The outer peripheral sight wall 34b is a thin plate-like member that protrudes inward in the sight direction from the interior portion of the bottom wall 34a. The surface wall 34c gradually slopes outward from the exterior edge of the bottom wall 34a toward the interior, then extends in the sight direction toward the interior. The surface wall 34c protrudes inward more than the outer peripheral sight wall 34b. In the illustrated example, the surface wall 34c is formed to have a protrusion dimension more than twice that of the outer peripheral sight wall 34b. The inner peripheral sight wall 34d extends in the sight direction from the inner peripheral edge of the surface wall 34c toward the interior. The interior edge of the inner peripheral sight wall 34d is provided with a mounting recess 34g that opens toward the interior and allows the attachment of the retaining rubber 32a of the net 32. The inner peripheral sight wall portion 34e extends in the sight direction from the extending edge portion of the inner peripheral sight wall portion 34d toward the inner periphery.

[0019] As shown in Fig. 6, the small end faces of the frame members 34 extend in a direction substantially perpendicular to the longitudinal direction, and are connected to each other by resin cap members 40. The cap members 40 have the same shape at their four corners, and as shown in Figs. 7 and 8, a cap body 41, two insertion portions 42, and two locking tongue portions 43 are integrally molded.

[0020] The cap body 41 has a square-shaped front panel 41a and four side panel portions 41b, 41c provided on the four sides of the front panel 41a. The front panel 41a is formed so that the length of each side is approximately the same as the front wall portion 34c of the frame member 34. The side panel portions 41b, 41c are flat plates extending from the four sides of the front panel 41a toward the interior of the room and form an exhaust port 41d in the portion of the cap body 41 facing the interior. Of these, two side panel portions (hereinafter referred to as covering side panel portions (partition wall portions) 41b when distinguishing them) adjacent to each other across a corner on the inner periphery of the screen door frame 31 of the cap body 41 are formed with a shape and dimensions that allow them to cover the small end face of the frame member 34. Each of the two covering side panel portions 41b is provided with a curved recess 44 and a communication hole 45. The curved recesses 44 connect the mounting recesses 34g of the frame member 34 when the cap member 40 is attached to the end of the frame member 34. Both ends of the curved recesses 44 open to the covering side panel portion 41b and extend in a curved shape between them. The communication holes 45 are through-holes formed only in the outer peripheral portion of the covering side panel portion 41b, and are formed at multiple positions equidistant from each other from the outer peripheral side to the inner peripheral side. The communication hole 45 formed in the outermost portion is elongated horizontally so as to include a portion that is an extension of two water guide grooves 34f formed in the frame member 34 when the insertion portion 42 (described later) is inserted into the frame member 34. As shown in FIG. 8(b), the outer peripheral opening edge of the outermost communication hole 45 is formed so as to be closer to the outer periphery than the inner bottom surface of the water guide grooves 34f. The other two side panel portions 41c are formed so that when the insertion portion 42 described later is inserted into the frame material 34, the position of the inner bottom surface is on the same plane as the bottom wall portion 34a of the frame material 34 or on the outer periphery side.

[0021] The insertion portion 42 is a protrusion provided on the covering side panel portion 41b, and can be inserted into the small end face of the frame material 34. In the illustrated example, the insertion portion 42 is configured to have a guide wall 42a extending along the interior surface of the surface wall portion 34c provided on the frame material 34, and an abutment wall 42b extending along the exterior surface of the outer peripheral sight wall portion 34b provided on the frame material 34. The insertion portion 42 can be press-fitted between the surface wall portion 34c and the outer peripheral sight wall portion 34b, thereby positioning the cap body 41 on the small end face of the frame material 34.

[0022] The locking tongue portion 43 is a protrusion provided on the covering side panel portion 41b at a portion closer to the outer periphery than the abutting wall 42b. In the example shown, the locking tongue portion 43 is provided so as to extend along the surface facing the exterior of the outer peripheral sight wall portion 34b provided on the frame material 34. The protruding dimension of the locking tongue portion 43 is set shorter than that of the insertion portion 42. The locking tongue portion 43 is provided with a locking protrusion 43a that functions as a barb on the portion of the extending edge facing the interior of the room.

[0023] 6, the cap member 40 having the above configuration has the locking notches 35 locked in the portions of the outer peripheral sight wall 34b of the frame members 34 that correspond to the locking protrusions 43a of the locking tongues 43, and from this state, the insertion portions 42 and locking tongues 43 are inserted from the small end faces of the frame members 34, thereby maintaining the two frame members 34 connected to each other. That is, as described above, the insertion portions 42 are press-fitted between the surface wall 34c and the outer peripheral sight wall 34b, and the locking protrusions 43a of the locking tongues 43 are locked in the locking notches 35, thereby restricting movement of the cap member 40 in the removal direction relative to the frame members 34, and the two frame members 34 are connected to each other in a state where they are approximately perpendicular to each other. After the frame material 34 is installed around all four sides, the opening is covered with the net 32 from the inside of the room, and from this state the edges of the net 32 and a series of pressure rubbers 32a are pressed into the mounting recess 34g and the curved recess 44 to form the lattice screen door 30.

[0024] The lattice screen door 30 configured as described above is attached to the door frame 10 by, for example, overlapping the outer peripheral sight wall 34b of the upper frame member 34A with the inwardly bent portion of the upper door support wall 11Ab of the upper door frame 11 and screwing the outer peripheral sight wall 34b through the upper door support wall 11Ab. Also, although not shown in the drawings, a locking portion is provided between the outer peripheral sight wall 34b of the side frame member 34C and the vertical door outer sight wall 13ABc of the vertical door frames 13, 14 to limit their movement relative to each other.

[0025] Meanwhile, between the lower frame member 34B and the lower door frame 12, the outer peripheral sight wall 34b of the lower frame member 34B abuts against the extended edge of the lower door support wall 12Ad via the upper edge of its sight surface facing the interior of the room. This results in a gutter 36 formed along the length of the lower frame member 34B by the bottom wall 34a, the outer peripheral sight wall 34b, and the top wall 34c, located outside and below the lower door support wall 12Ad of the lower door frame 12. Although the covering side panels 41b of the cap member 40 are disposed at both ends of this gutter 36, it communicates with the interior of the cap body 41 through the communication holes 45 and with the exterior through the outlet 41d provided in the interior portion of the cap body 41. Furthermore, the upper surface of the bottom wall 34a, which forms the inner bottom surface of the gutter 36, is provided with a plurality of narrow water guide grooves 34f along the entire length of the gutter.

[0026] With a back door constructed as described above, even when the door panel 2 is closed, the inner and outer screens 20A and 20B can be moved up and down to open the opening in the door frame 10, allowing ventilation through the door panel 2, which is convenient for ventilating the room. Moreover, because the door frame 10 is provided with a lattice screen 30 on the part facing the outside, there is no risk of insects or other foreign objects entering the room, and it is also advantageous in that it provides security.

[0027] Furthermore, as described above, the lower frame member 34B of the screen door frame 31 has a longitudinal gutter 36 formed between it and the lower door frame 12 of the door frame 10. Therefore, rainwater or other water that seeps over the lattice screen door 30 and into the door panel 2 is guided to the lower door support wall 12Ad of the lower door frame 12 and collects in the gutter 36 of the lower frame member 34B. It is then guided through the communication holes 45 to the cap members 40 at both ends and then drained to the outside through the drain outlets 41d. This eliminates the risk of water accumulating between the screen door frame 31 and the door frame 10. In particular, the bottom wall 34a of the lower frame has a water guide groove 34f on its upper surface, which prevents water accumulating in the gutter 36 from forming granules and accumulating, thereby improving the drainage performance of a back door equipped with a lattice screen door 30. Incidentally, the cap member 40 is also commonly used between the upper frame member 34A and the left and right side frame members 34C. However, the exhaust port 41d of the cap member 40 opens in the portion facing the door panel 2, i.e., toward the interior of the room. In addition, the covering side panel portion 41b separating the upper frame member 34A has the communication hole 45 only on the outer periphery, i.e., the upper portion. Therefore, there is no risk of water infiltrating the screen door frame 31 through the exhaust port 41d and communication hole 45 provided in the upper cap member 40. In addition, because the covering side panel portion 41b is interposed between the cap member 40 and the frame member 34, there is no risk of insects or other foreign objects entering between the lattice-equipped screen door 30 and the door panel 2 through the exhaust port 41d of the cap member 40.

[0028] In the above-described embodiment, the frame is exemplified as a door frame 10 constituting the door panel 2 of a back door. However, the present invention is not limited to this and can be applied to a frame attached to a building frame. The frame does not necessarily have to have a shoji screen that can be opened and closed; it can simply have a translucent panel, such as a fixed window. Furthermore, while a lattice screen door 30 is exemplified as an exterior component, it is not necessarily limited to a lattice screen door as long as it has an exterior frame. For example, an exterior component with a grid or latticework on the exterior frame may also be used. Furthermore, while the exterior component is exemplified as having a frame material with a common cross-sectional shape on all four sides, the frame material does not necessarily have to have a common cross-sectional shape on all four sides.

[0029] Furthermore, in the above-described embodiment, cap members 40 are provided around the four periphery of the exterior member, but it is sufficient if cap members 40 are provided only at the end of at least the lower frame member 34B. In the above-described embodiment, when cap members 40 are provided around the four periphery of the exterior member, the cap members have the same shape, but the present invention is not limited to this. Furthermore, although the cap member 40 is provided with a covering side panel portion 41b that serves as a partition wall, it is not necessary to have a partition wall portion. Furthermore, while the drain port 41d is provided only in the cap member 40, it is also possible to provide a drain port in the middle of the lower frame member so that it communicates with the water guide groove. In this case, the exterior member does not necessarily have to have a cap member.

[0030] As described above, the building fixture of the present invention is a building fixture that has an exterior member on the part of the frame body that faces outside the room, and the exterior member is attached to the frame body via an exterior frame body, and the lower frame material that forms the lower edge of the exterior frame body has a gutter section that runs along the length between it and the frame body, and the inner bottom surface of the gutter has a water-guiding groove that extends along the length and is continuous with an outlet to the outside. According to this invention, water that seeps in between the exterior member and the frame is collected in the gutter and is then drained to the outside through the gutter. Moreover, because the gutter has a water guide groove on the inner bottom surface, it is possible to prevent the water that has collected in the gutter from forming granules and stagnating, thereby improving the drainage of the fixture equipped with the exterior member.

[0031] The present invention is also characterized in that in the above-mentioned fitting, a cap member is provided at the end of the lower frame member, and the discharge outlet is provided in the cap member. According to this invention, water accumulated in the gutter can be discharged to the outside through the outlet provided in the cap member at the end without being discharged midway.

[0032] The present invention is also characterized in that, in the above-mentioned building fixture, a partition wall portion is provided between the lower frame material and the cap member, and the partition wall portion is provided with a communication hole that connects the lower frame material and the cap member. According to this invention, the partition wall portion is interposed between the cap member and the gutter portion of the lower frame member, so that foreign objects such as insects can be prevented from entering from the outside.

[0033] Furthermore, the present invention is characterized in that in the above-mentioned fittings, the communication hole has a width greater than that of the water guide groove of the gutter portion. According to this invention, drainage from the gutter portion can be ensured.

[0034] Furthermore, the present invention is characterized in that in the above-mentioned fitting, the cap member is provided with the exhaust outlet in a portion facing the interior of the room. According to this invention, even if parts are shared when a cap member is provided at the end of an upper frame member in an exterior frame body, it is possible to prevent external water from entering through the drainage hole of the upper cap member.

[0035] The present invention is also characterized in that, in the above-mentioned building fixture, the frame body is provided with a guide wall portion that becomes lower toward the lower frame material, and the gutter portion is provided in a portion that is lower than the lower edge of the guide wall portion. According to this invention, water that has entered between the exterior member and the frame body is discharged into the gutter through the guide wall portion. [Explanation of symbols]
