Description

[Technical Field]

[0001] The present invention relates to a fitting using a composite frame material having a metal frame material made of metal and a resin frame material made of synthetic resin. [Background technology]

[0002] Conventionally, there has been known a fitting having a frame body in which a composite frame material, which is a combination of a metal frame material formed from an aluminum extrusion and a resin frame material formed from a resin extrusion, is used for the upper frame, lower frame, and left and right vertical frames (see, for example, Patent Document 1). In the frame body of this fitting, horizontal frames, which form the upper and lower frames, are placed between the upper and lower ends of the left and right vertical frames, and the longitudinal ends of the horizontal frames are joined facing the sides of the vertical frames. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2018-48484 A Summary of the Invention [Problem to be solved by the invention]

[0004] In frames used for horizontal and vertical frames made of composite frame materials, such as the frame of the conventional building fixture described above, if a large external force is accidentally applied, the resin frame materials may be deformed or damaged, requiring the replacement of the resin frame materials. When replacing the resin frame materials, it is desirable to remove only the resin frame materials while leaving the metal frame materials fixed to the main body, in order to facilitate the work. However, for example, in the case of the conventional frame described above, where the longitudinal ends of the horizontal frames are joined facing the sides of the vertical frames, the resin frame materials of the horizontal members can be removed, but the resin frame materials of the vertical members may interfere with the metal frame materials of the horizontal members and cannot be removed, even if the resin frame materials of the horizontal members are removed.

[0005] For this reason, the interfering portions of the metal frame members of the horizontal members are cut out so that the resin frame members of the vertical members can be removed. In a frame body in which one end of the vertical frame and the horizontal frame are joined facing the other side, if a cutout is provided at the joint between the horizontal frame and the vertical frame, there is a risk that the watertightness of the joint between the horizontal frame and the vertical frame will decrease.

[0006] The present invention was made in consideration of such problems, and its purpose is to provide a building fixture that has excellent water-tightness while allowing the resin frame material of the frame body using composite frame material to be removable. [Means for solving the problem]

[0007] The main invention for achieving this object is a fitting having a frame body framed with a plurality of composite frame materials, each frame being formed by fitting together a resin frame made of synthetic resin and a metal frame made of metal, wherein one of the two composite frame materials that are adjacent to each other and joined together has a visible surface formed by cutting away a portion of the metal frame that protrudes toward the other composite frame material, and is joined to the other of the two composite frame materials via a first water-stopping member between the visible surface and an end of the other composite frame material in the longitudinal direction, and the wood of one of the composite frame materials is The longitudinal end of the oil frame is positioned opposite the visible surface of the resin frame of the other composite frame material, and is removably attached to the metal frame of one of the composite frame materials, and the protruding portion of the metal frame of one of the composite frame materials is cut away to form the visible surface so that the resin frame of the other composite frame material can be released from the engagement with the metal frame and removed, and this is a fitting characterized in that a second water-stopping member is provided on the visible surface at a portion that faces the end of the other resin frame when framed and when moved. Other features of the present invention will become apparent from the description of this specification and the accompanying drawings. [Effects of the Invention]

[0008] According to the present invention, it is possible to provide a fitting that has excellent water-tightness while allowing the resin frame material of the frame body using a composite frame material to be removable. [Brief explanation of the drawings]

[0010] Hereinafter, a fitting according to one embodiment of the present invention will be described with reference to the drawings. As an example of a fitting 1 according to this embodiment, as shown in Figures 1 and 2, we will explain a fitting 1 having a frame body 2 fixed to the building's framework to form an opening 1b, and a door 3 acting as a shoji screen attached to the frame body 2 via a hinge 1a so that it can be opened and closed freely.

[0011] As shown in Figure 2, the fitting 1 of this embodiment has a door 3 attached to the left vertical frame 4 that constitutes the frame body 2 via a hinge 1a so that it can be opened and closed freely. In the following explanation, when the fitting 1 attached to a building or the like is viewed from the indoor side, the direction that is up and down is referred to as the up-down direction, the direction that is left and right is referred to as the left-right direction, and the depth direction that is the indoor / outdoor direction is referred to as the front direction. In addition, in the front direction, the side that the door 3 moves to when it opens is referred to as the outdoor side, and the opposite side where a door stop is provided is referred to as the indoor side.

[0012] The frame body 2 is framed in a rectangular shape by a pair of vertical frames 4 arranged on the left and right and a pair of horizontal frames 5 arranged above and below. The vertical frames 4 and horizontal frames 5 of the frame body 2 are joined with water-stopping members 15, 16 (described later) interposed between the visible surface of the vertical frames 4 and the longitudinal ends of the upper and lower horizontal frames 5. The joint between the vertical frames 4 and horizontal frames 5 will be explained below using the joint between the left vertical frame 4 and the lower horizontal frame 5 as an example. In the left vertical frame 4 (hereinafter simply referred to as the vertical frame), the inside of the frame body is the right side, and the outer periphery is the left side. In the lower horizontal frame 5 (hereinafter simply referred to as the lower frame), the inner periphery of the frame body 2 is the upper side, and the outer periphery is the lower side.

[0013] As shown in Figure 3, the lower frame 5 has a lower frame body 9 made of a composite member in which a metal lower frame 7 made of metal and a resin lower frame 8 made of synthetic resin are fitted together, and a lower seal material 10 that is provided along the longitudinal direction of the lower frame body 9 and serves as a door stop for the door 3. The metal lower frame 7 and the resin lower frame 8 are both extruded members with their extrusion direction in the left-right direction (longitudinal direction).

[0014] The metal lower frame 7 has a lower frame surface portion 7b with a lower frame opposing surface 7a that faces the lower surface 3a, which is the outer peripheral surface of the door 3, when the door 3 is closed, and a lower frame extension portion 7c that extends upward on the indoor side beyond the lower frame surface portion 7b, and the lower frame extension portion 7c is provided with two metal engagement portions 7d with which the resin lower frame 8 engages.

[0015] The resin sill 8 has an outdoor part 8a that fits over the overhanging part 7c and covers the top of the overhanging part 7c, and an indoor part 8b that is provided on the indoor side of the outdoor part 8a and fixed to the building frame. The underside of the outdoor part 8a is provided with resin engagement pieces 8c that hang down from the center in the projection direction and the indoor side edge and engage with two metal engagement pieces 7d provided on the metal sill 7.

[0016] The lower frame 5 is joined to the metal lower frame 7 by two resin engagement pieces 8c of the resin lower frame 8 engaging with two metal engagement parts 7d of the metal lower frame 7. The resin lower frame 8 can be removed by pulling it upward to release the engagement between the resin engagement pieces 8c and the metal engagement parts 7d.

[0017] A lower seal material 10 is provided on the outdoor side of the lower frame extension 7c. The lower seal material 10 is fitted into a lower seal fitting portion 7f that is provided on a facing surface 7e of the lower frame extension 7c that faces the outdoors (hereinafter referred to as the extension facing surface) and has a recess that is recessed toward the indoor side, and is provided so as to protrude toward the outdoor side of the lower frame extension 7c.

[0018] The lower frame outdoor section 8a is provided on the lower frame extension section 7c, forming a horizontal surface, and has a lower frame extension section 8d whose outdoor end extends downward. The outdoor facing surface 8e of the lower frame extension section 8d (hereinafter referred to as the extension section facing surface) and the extension section facing surface 7e form approximately the same plane.

[0019] When the door 3 is closed, the lower seal material 10 fitted into the lower seal fitting portion 7f is pressed by the door 3 toward the lower frame extension portion 7c, and abuts against the extension portion visible surface 8e and the extension portion visible surface 7e, so that the upper surface of the lower seal material 10 and the upper surface of the lower frame outdoor portion 8a form approximately the same horizontal plane.

[0020] As shown in Fig. 4, the vertical frame 4 has a vertical frame body 13 made of a composite member in which a metal vertical frame 11 made of metal and a resin vertical frame 12 made of synthetic resin are fitted together, and a vertical seal material 14 that is provided along the longitudinal direction of the vertical frame body 13 and serves as a door stop for the door 3. Furthermore, both the metal vertical frame 11 and the resin vertical frame 12 are extruded members whose extrusion direction is the up-down direction (longitudinal direction).

[0021] The vertical metal frame 11 has a generally rectangular cross section that is long in the projection direction and a hollow metal frame portion 11a that penetrates vertically. The vertical metal frame 11 has an inner peripheral wall portion 11b that defines the hollow metal frame portion 11a and forms the inner peripheral surface facing the opening 1b formed by the frame body 2, an outer peripheral wall portion 11c that faces the inner peripheral wall portion 11b on the outer peripheral side with a gap in the left-right direction, an indoor sighting surface portion 11d that connects the indoor side end of the inner peripheral wall portion 11b and the outer peripheral wall portion 11c and forms a sighting surface, and a fixing piece 11e that protrudes from the outer peripheral side from the outer peripheral wall portion 11c and is fastened to the frame with a screw.

[0022] The inner peripheral wall 11b has an outdoor portion 11f on the outdoor side and an indoor portion 11g on the indoor side, with the indoor portion 11g being located closer to the outer periphery than the outdoor portion 11f and having a step. As shown in Figure 2, a door 3 is attached to the outdoor portion 11f of the inner peripheral wall 11b via a hinge 1a so as to be able to be opened and closed freely.

[0023] The indoor visible surface portion 11d extends from the indoor end of the indoor portion 11g toward the outer periphery, and a recess 11h recessed toward the outdoor side is provided at the end where the extended outer periphery end connects to the outer periphery wall portion 11c.

[0024] Near the inner peripheral edge of the indoor sighting surface 11d, a first metal engaging piece 11i is provided, which extends indoors and has its end extending inward to engage with the vertical resin frame 12. Also, on the inner peripheral side of the indoor sighting surface 11d, a protruding piece 11j is provided, which protrudes more inward than the indoor side portion 11g and extends along the indoor sighting surface 11d.

[0025] The tip of the protruding piece 11j protrudes by the difference in level between an outdoor-side visible surface 11k facing the opening 1b of the outdoor portion 11f and an indoor-side visible surface 11l facing the opening 1b of the indoor portion 11g.

[0026] An indoor-side extension piece 11m is provided at the indoor-side end of the outer peripheral wall portion 11c that extends indoors beyond the indoor-facing surface portion 11d, and a second metal engagement piece 11n that engages with the vertical resin frame 12 is provided on the outdoor side of the indoor-side extension piece 11m. The second metal engagement piece 11n is provided on the outdoor side of the indoor-side extension piece 11m so as to face each other with a small gap between them. A hook piece 11o that protrudes indoors is provided at the inner end of the second metal engagement piece 11n.

[0027] The vertical resin frame 12 has a resin frame hollow portion 12a that has a substantially rectangular cross section that is long in the left-right direction and penetrates in the up-down direction. The vertical resin frame 12 has a resin wall portion 12b that forms the resin frame hollow portion 12a and forms a wall portion along the projection direction on the outer periphery side, a vertical seal material fitting portion 12c that fits with a vertical seal material 14 provided on the outdoor side of the resin frame hollow portion 12a, and a first resin engaging piece 12e that is connected to the vertical seal material fitting portion 12c at a facing surface 12d, extends to the outer periphery, and engages with the first metal engaging piece 11i.

[0028] The resin wall portion 12b has a resin fixing piece 12f that extends indoors and is fastened to the frame with a screw. The resin fixing piece 12f forms the resin frame hollow portion 12a and is provided with a second resin engaging piece 12h that protrudes outward and engages with the second metal engaging piece 11n on the indoor side beyond the indoor wall portion 12g that faces indoors.

[0029] The second resin engaging piece 12h has a tip sighting surface 12i on the outer circumferential side, which is the tip side, located outside of the inner circumferential part and forming a sighting surface. The outdoor end of the resin wall portion 12b extends outward and has a resin extension piece 12j that extends outside.

[0030] The vertical frame 4 is joined to the vertical metal frame 11 by fitting together the vertical resin frame 12 with the vertical metal frame 11, with the first resin engagement pieces 12e of the vertical resin frame 12 engaging with the first metal engagement pieces 11i of the vertical metal frame 11 and the second resin engagement pieces 12h of the vertical resin frame 12 engaging with the second metal engagement pieces 11n of the vertical metal frame 11. The vertical resin frame 12 can be removed by moving it inward to release the engagement between the first resin engagement pieces 12e and the second resin engagement pieces 12h and the first metal engagement pieces 11i and the second metal engagement pieces 11n.

[0031] The resin vertical frame 12 joined to the metal vertical frame 11 protrudes inward beyond the outdoor-side visible surface 11k and the indoor-side visible surface 11l that face the opening 1b of the outdoor-side portion 11f and the indoor-side portion 11g, and a vertical seal material 14 is provided on the outdoor side of the protruding protrusion 12k to form the door stop portion of the door 3.

[0032] The vertical frame 4 and the lower frame 5 are joined via a waterproof sheet 6 placed on the lower frame 5. The waterproof sheet 6 is, for example, a so-called sponge made of synthetic resin. As shown in Figures 3 and 4, the waterproof sheet 6 is placed from above the outdoor lower frame portion 8a of the resin lower frame 8 of the lower frame 5 to above the lower sealant 10 provided on the outdoor side of the resin lower frame 8. It is interposed and compressed between the resin vertical frame 12 of the vertical frame 4 to be placed and the vertical sealant 14 provided on the outdoor side of the resin vertical frame 12. When the vertical frame 4 and the lower frame 5 are joined, the longitudinal end 12l of the resin vertical frame 12 is positioned vertically opposite the outdoor lower frame portion 8a and the indoor lower frame portion 8b, which form the visible surface of the resin lower frame 8. Therefore, in order to remove the resin lower frame 8, the resin vertical frame 12 must first be removed.

[0033] 5 and 6, the vertical frame 4 and the lower frame 5 are joined at the longitudinal end 5a of the lower frame 5 via water-stopping members 15, 16. As shown in FIG. 7, the lower end of the metal vertical frame 11 of the vertical frame 4 has a visible surface 11p formed at a location facing the longitudinal end 5a of the lower frame 5.

[0034] The visible surface 11p is the inner peripheral surface of the outer peripheral wall portion 11c, and the lower end portions of the indoor extension piece 11m and the second metal engagement piece 11n provided on the metal vertical frame 11 are cut away, and the first metal engagement piece 11i provided on the indoor visible surface portion 11d is also cut away. This allows the longitudinal end 5a of the lower frame 5 to face the visible surface 11p via the water-stopping members 15, 16.

[0035] 8(a), the visible surface 11p provided on the vertical metal frame 11 is formed by removing the lower end portions of the indoor extension piece 11m and the second metal engagement piece 11n so as to have an opposing region R1 that faces the end 8f of the resin lower frame 8 when the vertical frame 4 and the lower frame 5 are joined, and an expanded region R2 that expands above the opposing region R1 so that, after the vertical resin frame 12 is removed, the resin lower frame 8 can be lifted and moved upward to release the engagement with the metal lower frame 7 and remove it, as shown in FIG. 8(b). Note that the lower end portions of the inner peripheral wall portion 11b and the outer peripheral wall portion 11c that form the metal frame hollow portion 11a of the vertical metal frame 11 are also removed so that the entire end of the metal lower frame 7 can face the visible surface 11p via the water-stopping member.

[0036] The first water-stopping member 15, provided on the visible surface 11p of the metal vertical frame 11, is provided so as to extend from the portion where the end 5a of the lower frame 5 faces to the expanded portion R2 when the vertical frame 4 and the lower frame 5 are joined, and the second water-stopping member 16 is provided on the surface of the first water-stopping member 15 facing the lower frame 5 in an area including the expanded portion R2 and the opposed portion R1. The second water-stopping member 16 is made of a material with a higher compressibility than the first water-stopping member 15. For example, butyl rubber is used for the first water-stopping member 15, and ethylene propylene rubber, which has a higher compressibility than the first water-stopping member 15, is used for the second water-stopping member 16.

[0037] According to the fitting 1 of this embodiment, the metal vertical frame 11 of the vertical frame 4 has a projection surface 11p, through which the first water-stopping member 15 and the second water-stopping member 16 are interposed between the metal vertical frame 11 and the longitudinal end 5a of the bottom frame 5, formed by cutting out the indoor extension piece 11m and the second metal engagement piece 11n that project toward the bottom frame 5. This projection surface 11p is provided above the opposing portion R1 that faces the resin bottom frame 8 of the bottom frame 5, with an expansion portion R2 to make the resin bottom frame 8 removable. Therefore, after removing the resin vertical frame 12, the resin bottom frame 8 can be removed by pulling it upward without removing the metal vertical frame 11 or separating the vertical frame 4 and the bottom frame 5, thereby releasing the engagement between the resin engagement piece 8c and the metal engagement portion 7d.

[0038] Furthermore, since the second water-stopping member 16 is provided on the visible surface 11p of the metal vertical frame 11 in an area including the expanded portion R2 and the opposing portion R1, even if the protruding indoor extension piece 11m and the second metal engagement piece 11n of the metal vertical frame 11 are cut away, the gap created in the cut-out portion can be blocked by the second water-stopping member 16, thereby preventing the infiltration of rainwater, etc. This makes it possible to provide a fitting 1 with even better water-stopping properties.

[0039] Furthermore, because the second water-stopping member 16 has a higher compressibility than the first water-stopping member 15, when removing the resin lower frame 8, it can be more easily removed by compressing it more. Furthermore, since resin frame materials tend to expand and contract due to temperature changes, by interposing the second water-stopping member 16 between the longitudinal end 8f of the resin lower frame 8 and the metal vertical frame 11, even if the resin lower frame 8 expands and contracts, the second water-stopping member 16 expands and contracts in response to this expansion and contraction, making it possible to maintain excellent water-stopping properties.

[0040] Furthermore, since the second water-stopping member 16 is provided overlapping the first water-stopping member 15, there is no portion where the water-stopping member is interrupted between the first water-stopping member 15 and the second water-stopping member 16. This makes it possible to provide a fitting 1 with superior water-stopping properties.

[0041] In the above embodiment, the joint between the left vertical frame and the lower frame was used as an example, but the joint is not limited to the joint between the left vertical frame and the lower frame as long as the vertical frame and the horizontal frame are joined together in the frame body. Also, in the above embodiment, an example was described in which the longitudinal end of the horizontal frame is joined to the visible surface of the vertical frame, but this is not limited to this, and the frame body may be joined to the visible surface of the horizontal frame, with the longitudinal end of the vertical frame facing the visible surface of the horizontal frame.

[0042] The above-described embodiments are provided to facilitate understanding of the present invention and are not intended to limit the present invention. The present invention may be modified or improved without departing from the spirit thereof, and the present invention includes equivalents thereof. The present embodiment includes at least the following inventions.

[0043] A fixture having a frame body framed with a plurality of composite frame materials, each of which is formed by fitting a resin frame made of synthetic resin and a metal frame made of metal, wherein one of the two composite frame materials that are adjacent to each other and joined together has a visible surface formed by cutting off a portion of the metal frame that protrudes toward the other composite frame material, and is joined to the other composite frame material via a first water-stopping member between the visible surface and the longitudinal end of the other composite frame material of the two composite frame materials, and the resin frame of one of the composite frame materials is is positioned opposite the visible surface of the resin frame of the other composite frame material and is removably attached to the metal frame of one of the composite frame materials, the protruding portion of the metal frame of one of the composite frame materials is cut away to form the visible surface so that the resin frame of the other composite frame material can be released from the engagement with the metal frame and removed, and a second water-stopping member is provided on the visible surface at a portion that faces the end of the other resin frame when framed and when moved.

[0044] With this type of building fixture, the metal frame of one composite frame material has a projecting surface formed by cutting out the protruding portion toward the other composite material, through which a first water-stopping member is interposed between the metal frame and the longitudinal end of the other composite frame material.This projecting surface has been formed by cutting out the protruding portion so that the resin frame of the other composite frame material can be moved to release it from its engagement with the metal frame and remove it.Therefore, after removing one resin frame, it is possible to remove the other resin frame without removing one metal frame or separating the two composite frame materials.

[0045] Furthermore, since a second water-stopping member is provided on the visible surface of one of the metal frames in a position that faces the edge of the other resin frame when the frame is assembled and when it is moved, even if a protruding portion of one of the composite members is cut away, the second water-stopping member can close the gap that occurs in the cut-away portion, preventing rainwater and the like from seeping in. This makes it possible to provide fittings with even better water-stopping properties.

[0046] In such a fitting, the second water-stopping member has a higher compressibility than the first water-stopping member. With this type of fitting, the second water-stopping member has a higher compressibility than the first water-stopping member, so when removing the other resin frame, it can be compressed more to remove the other resin frame more easily. Also, since resin frames tend to expand and contract due to temperature changes, by interposing the second water-stopping member between the longitudinal end of the other resin frame and one of the metal frames, even if the other resin frame expands and contracts, the second water-stopping member expands and contracts in response to that expansion and contraction, making it possible to maintain excellent water-stopping properties.

[0047] Such a fixture is characterized in that the second water-stopping member is provided overlapping the first water-stopping member. In such a fitting, the second waterproofing member is provided overlapping the first waterproofing member, so there is no gap between the first and second waterproofing members, making it possible to provide better waterproofing properties.
