[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 that uses 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, as the upper frame, lower frame, and left and right vertical frames (see, for example, Patent Document 1). In the composite frame material provided in this fitting, the facing piece of the resin frame material is attached to the resin frame mounting piece of the metal frame material with screws.

[0003] [Patent Document 1] Patent Publication No. 2021-1470 Summary of the Invention [Problem to be solved by the invention]

[0004] The composite frame materials used for the top, bottom, and left and right vertical frames of the above-mentioned conventional building fixtures are formed by screwing together resin frame materials and metal frame materials, which requires each composite frame material to be screwed together individually, making manufacturing cumbersome and costly. To make the manufacturing of the composite frame materials easier, it is possible to attach the resin frame materials to the metal frame materials by engaging them, for example. However, simply engaging the resin frame materials with the metal frame materials poses a problem in that rainwater and other elements may seep in through gaps that form at the engagement points between the resin and metal frame materials.

[0005] The present invention has been made in view of the above problems, and its object is to provide a building fixture using a composite frame material that is easy to manufacture and has excellent water-stopping properties. [Means for solving the problem]

[0006] The main invention for achieving this purpose is a fixture having a frame body framed by a composite frame material having a metal frame material made of metal and a resin frame material made of synthetic resin adjacent to each other in the projection direction, wherein the metal frame material has metal engaging pieces on the outdoor side and the indoor side in the projection direction, and the resin frame material has resin engaging pieces on the outdoor side and the indoor side in the projection direction, and the metal engaging pieces on the outdoor side and the resin engaging pieces on the outdoor side, and the metal engaging pieces on the indoor side and the resin engaging pieces on the indoor side all engage in abutting contact with each other in the projection direction, thereby joining the metal frame material and the resin frame material. Other features of the present invention will become apparent from the description of this specification and the accompanying drawings. [Effects of the Invention]

[0007] According to the present invention, it is possible to provide fittings using composite frame materials that are easy to manufacture and have excellent water-stopping properties. [Brief explanation of the drawings]

[0008] [Figure 1] FIG. 2 is a cross-sectional view of the fitting according to the present embodiment. [Figure 2] FIG. 2 is a diagram showing the metal frame material and resin frame material that make up the vertical frame. [Figure 3] FIG. 2 is an enlarged view of part A in FIG. [Figure 4] FIG. 4 is a diagram showing a modification of part B in FIG. DETAILED DESCRIPTION OF THE INVENTION

[0009] 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 Figure 1, we will explain a fitting 1 having a frame body 2 fixed to the building's framework and forming an opening 1b, and a door 3 serving as a shoji screen attached to the frame body 2 via a hinge 1a so that it can be opened and closed freely.

[0010] As shown in Figure 1, in the fitting 1 of this embodiment, the door 3 is attached to the left vertical frame 20 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 up-down direction is referred to as the up-down direction, the left-right direction 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. Furthermore, the opening 1b side that is inside the frame body 2 is referred to as the inner periphery side, and the outside of the frame body 2 opposite the opening 1b is referred to as the outer periphery side.

[0011] The vertical frame 20 is a composite frame material formed by engaging and joining a metal frame material 21 made of metal and placed on the outdoor side in the projection direction with a resin frame material 22 made of synthetic resin and placed on the indoor side in the projection direction. The metal frame material 21 and the resin frame material 22 are both extruded shapes with the vertical direction (longitudinal direction) as the extrusion direction.

[0012] The metal frame material 21 has a generally rectangular cross section that is long in the projection direction and a metal frame hollow portion 21a that penetrates in the vertical direction. The metal frame material 21 forms the metal frame hollow portion 21a and has an inner projection wall portion 21b that forms a projection surface on the inner periphery side that is the side of the opening 1b formed by the frame body 2, an outer projection wall portion 21c that is spaced apart from the inner projection wall portion 21b in the left-right direction and faces the outer periphery side, an outdoor sighting surface portion 21d that connects the outdoor end of the inner projection wall portion 21b and the outer projection wall portion 21c and forms a sighting surface, an indoor sighting surface portion 21e that connects the indoor end of the inner projection wall portion 21b and the outer projection wall portion 21c and forms a sighting surface, and a fixing piece 21f that protrudes outward from the outer periphery side and is fastened to the frame with a screw.

[0013] The inner peripheral projection wall 21b has an outdoor portion 21g on the outdoor side and an indoor portion 21h on the indoor side, with the indoor portion 21h being located more radially outward than the outdoor portion 21g and having a step. A door 3 is attached to the outdoor portion 21g of the inner peripheral projection wall 21b via a hinge 1a so as to be able to open and close freely. Here, the inner peripheral projection wall 21b corresponds to the projection wall on which the shoji screen is supported so as to be able to open and close freely, and the outdoor side projection surface 21i and the indoor side projection surface 21j facing the opening 1b correspond to the projection surfaces of the projection wall on which the shoji screen is supported so as to be able to be opened and closed freely.

[0014] The indoor visible surface portion 21e extends from the indoor side end of the indoor side portion 21h to the outer periphery, and a recess 21k recessed toward the outdoor side is provided at the end where the extended outer periphery end connects to the outer periphery visible wall portion 21c.

[0015] Near the inner peripheral edge of indoor sighting surface 21e, first metal engaging piece 21l is provided, which extends indoors and has its end extending inward to engage with resin frame material 22. Also, on the inner peripheral side of indoor sighting surface 21e, protruding piece 21m is provided, which protrudes inward further than indoor side portion 21h, extending along indoor sighting surface 21e.

[0016] The tip of the protruding piece 21m protrudes by the difference in level between the outdoor-side visible surface 21i facing the opening 1b of the outdoor-side portion 21g and the indoor-side visible surface 21j facing the opening 1b of the indoor-side portion 21h.

[0017] The outer peripheral visible wall portion 21c extends further outdoors than the outdoor visible surface portion 21d and further indoors than the indoor visible surface portion 21e. An indoor-side extension piece 21n extending inward is provided at the indoor-side end of the outer-periphery-side prospective wall portion 21c, and a second metal engagement piece 21o that engages with the resin frame material 22 is provided on the outdoor side of the indoor-side extension piece 21n. The second metal engagement piece 21o is provided so as to face the outdoor side of the indoor-side extension piece 21n with a slight gap between them.

[0018] A hook piece 21p that protrudes indoors is provided at the inner peripheral end of the second metal engagement piece 21o. Here, the first metal engagement piece 21l corresponds to the metal engagement piece provided on the outdoor side of the metal frame material 21, and the second metal engagement piece 21o corresponds to the resin engagement piece provided on the indoor side of the metal frame material 21. Furthermore, the indoor side extension piece 21n corresponds to a facing piece that faces the metal engagement piece (second metal engagement piece 21o) with a gap in the forward direction.

[0019] The resin frame material 22 has a resin frame hollow portion 22a that has a substantially rectangular cross section that is long in the left-right direction and penetrates in the up-down direction. The resin frame material 22 forms the resin frame hollow portion 22a and has a resin front wall portion 22b that forms a front surface on the outer periphery of the frame body 2, a seal material fitting portion 22c into which a seal material 4 provided on the outdoor side of the resin frame hollow portion 22a is fitted, and a first resin engaging piece 22d that is connected to the seal material fitting portion 22c at a front surface 22m, extends outward, and engages with the first metal engaging piece 21l.

[0020] The resin recessed wall portion 22b has a resin fixing piece 22e that extends indoors and is fastened to the frame with a screw. The resin fixing piece 22e forms the resin frame hollow portion 22a, and is provided with a second resin engaging piece 22g that protrudes outward and engages with the second metal engaging piece 21m on the indoor side beyond the indoor wall portion 22f that faces indoors.

[0021] The second resin engaging piece 22g has a leading end sighting surface portion 22h on the outer circumferential side, which is the leading end side, that is located closer to the exterior than the inner circumferential portion and forms a sighting surface. Here, the first resin engaging piece 22d corresponds to the resin engaging piece provided on the exterior side of the resin frame material 22, and the second resin engaging piece 22g corresponds to the resin engaging piece provided on the interior side of the resin frame material 22. The outdoor end of the resin visible wall portion 22b extends outward, and the extended end has a resin extension piece 22i that extends outward.

[0022] 3, the vertical frame 20 is joined to the metal frame material 21 by first resin engaging pieces 22d of the resin frame material 22 engaging with first metal engaging pieces 21l of the metal frame material 21 and second resin engaging pieces 22g of the resin frame material 22 engaging with second metal engaging pieces 21o of the metal frame material 21. The resin frame material 22 joined to the metal frame material 21 protrudes inward beyond the outdoor-side visible surface 21i and the indoor-side visible surface 21j that face the opening 1b of the outdoor-side portion 21g and the indoor-side portion 21h, and a sealant 4 is provided on the outdoor side of the protruding protrusion 22l, and the protruding portion 22l, together with the sealant 4, forms a door stop for the door 3.

[0023] When the resin frame material 22 and the metal frame material 21 are joined, on the outdoor side, the indoor-side surface 22j of the first resin engagement piece 22d abuts and engages with the outdoor-side surface 21q of the first metal engagement piece 21l, and on the indoor side, the outdoor-side surface 22k of the second resin engagement piece 22g abuts and engages with the indoor-side surface 21r of the second metal engagement piece 21o, thereby joining the metal frame material 21 and the resin frame material 22. Furthermore, the resin extension piece 22i of the resin frame material 22 abuts against the outer peripheral side visible wall portion 21c of the metal frame material 21, with its tip inserted into the recess 21k, and the tip visible surface portion 22h of the second resin engagement piece 22g being positioned on the outer peripheral side of the hook piece 21p of the metal frame material 21, thereby restricting relative movement between the metal frame material 21 and the resin frame material 22 in the left-right direction.

[0024] Furthermore, when the resin frame material 22 and the metal frame material 21 are joined together, the protruding piece 21m of the metal frame material 21 faces the outdoor facing surface 22m of the protruding portion 22l and protrudes toward the sealing material 4 fitted into the protruding portion 22l.

[0025] According to the building fixture 1 of this embodiment, the vertical frame 20 made of a composite frame material used in the frame body 2 of the building fixture 1 is joined by engaging the first metal engaging piece 21l with the first resin engaging piece 22d, and by engaging the second metal engaging piece 21o with the second resin engaging piece 22g, so it can be manufactured more easily than when joined with screws or the like, and the manufacturing time is shortened, making it possible to keep costs down.

[0026] Furthermore, on the outdoor side in the projection direction, the indoor-side surface 22j of the first resin engaging piece 22d abuts against the outdoor-side surface 21q of the first metal engaging piece 21l of the metal frame material 21 and the resin frame material 22, and on the indoor side, the outdoor-side surface 22k of the second resin engaging piece 22g abuts against the indoor-side surface 21r of the second metal engaging piece 21o. That is, the first and second metal engaging pieces 21l, 21o are sandwiched between the first and second resin engaging pieces 22d, 22g. Therefore, no gaps are formed between the first resin engaging piece 22d and the first metal engaging piece 21l, or between the second resin engaging piece 22g and the second metal engaging piece 21o, on either the outdoor side or the indoor side in the projection direction. This makes it difficult for rainwater and the like to seep in through the engagement areas between the first resin engaging piece 22d and the first metal engaging piece 21l, and between the second resin engaging piece 22g and the second metal engaging piece 21o. Therefore, it is possible to provide a fitting 1 using a vertical frame 20 that is easy to manufacture and has excellent water-stopping properties.

[0027] In addition, the metal frame material 21 has a protruding piece 21m that protrudes toward the inner periphery of the frame body 2 along the protruding portion 22l on the outdoor side of the protruding portion 22l that protrudes toward the inner periphery from the inner periphery side visible wall portion 21b of the metal frame material 21 in the resin frame material 22.Therefore, rainwater and the like that enters between the door 3 and the metal frame material 21 is blocked by the protruding piece 21m and is unlikely to enter directly into the protruding portion 22l. Furthermore, since the protruding piece 21m is provided along the protruding portion 22l further inward than the inner peripheral projection wall portion 21b provided on the inner peripheral side of the first and second metal engaging pieces 21l, 21o and the first and second resin engaging pieces 22d, 22g, even if rainwater or the like enters between the door 3 and the metal frame material 21, it is prevented from passing between the protruding portion 22l and the protruding piece 21m and entering the first and second metal engaging pieces 21l, 21o and the first and second resin engaging pieces 22d, 22g. This makes it possible to provide a fitting 1 with even better watertightness.

[0028] In the above embodiment, an example has been described in which first resin engaging piece 22d and first metal engaging piece 21l, and second resin engaging piece 22g and second metal engaging piece 21o are engaged while abutting in the forward direction, but for example, as shown in Fig. 4, second resin engaging piece 22g and second metal engaging piece 21o may be engaged, and further, indoor-side extending piece 21n of metal frame material 21 may be bent toward second metal engaging piece 21o by crimping, so that second resin engaging piece 22g is sandwiched between second metal engaging piece 21o and indoor-side extending piece 21n. In this case, second resin engaging piece 22g and second metal engaging piece 21o are more reliably abutted against each other, eliminating gaps, and making it possible to provide a fitting 1 with better watertightness.

[0029] In this case, even if the resin frame material 22 expands and contracts due to temperature changes, the second resin engaging piece 22g remains sandwiched between the second metal engaging piece 21o and the indoor extension piece 21n, thereby making it possible to prevent a gap from occurring between the second resin engaging piece 22g and the second metal engaging piece 21o.

[0030] In the above embodiment, the left vertical frame 20 has been described as an example, but the right vertical frame 20 is similar. Furthermore, in the above embodiment, an example was described in which the first and second metal engagement pieces 21l, 21o are clamped between the first and second resin engagement pieces 22d, 22g, but this is not limited to this, and the first and second resin engagement pieces may also be clamped between the first and second metal engagement pieces.

[0031] 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.

[0032] This is a fixture having a frame body framed by a composite frame material having a metal frame material made of metal and a resin frame material made of synthetic resin adjacent to each other in the projection direction, wherein the metal frame material has metal engaging pieces on the outdoor side and the indoor side in the projection direction, and the resin frame material has resin engaging pieces on the outdoor side and the indoor side in the projection direction, and the metal engaging pieces on the outdoor side and the resin engaging pieces on the outdoor side, and the metal engaging pieces on the indoor side and the resin engaging pieces on the indoor side all engage in abutting contact with each other in the projection direction, thereby joining the metal frame material and the resin frame material.

[0033] With such building materials, the composite frame material used for the frame of the building material is joined by engaging metal engaging pieces and resin engaging pieces, so it can be manufactured more easily than when joined with screws, etc., and the manufacturing time is shortened, making it possible to keep costs down.

[0034] In addition, the metal frame material and the resin frame material are engaged with each other in a state where the outdoor-side metal engaging piece and the outdoor-side resin engaging piece abut each other in the projection direction, and the indoor-side metal engaging piece and the indoor-side resin engaging piece abut each other in the projection direction. Therefore, the outdoor-side and indoor-side engaging parts joining the metal frame material and the resin frame material abut each other and do not create gaps, so rainwater and the like are less likely to seep in through the parts where the resin engaging piece and the metal engaging piece are engaged. This makes it possible to provide building materials using composite frame materials that are easy to manufacture and have excellent water-tight properties.

[0035] Also, the building fixture has a frame body framed by a composite frame material having a metal frame material made of metal and a resin frame material made of synthetic resin adjacent to each other in the projection direction, wherein the metal frame material has a metal engaging piece and a facing piece facing the metal engaging piece with a gap in the projection direction, the resin frame material has a resin engaging piece located between the metal engaging piece and the facing piece and engaging with the metal engaging piece, and the facing piece is bent to clamp the resin engaging piece together with the metal engaging piece.

[0036] With such fittings, the composite frame material used for the frame of the fittings has a metal engaging piece and a resin engaging piece engaged with each other, and the bent facing piece is joined by clamping the resin engaging piece together with the metal engaging piece, making it easier to manufacture than when joined with screws or the like.

[0037] Furthermore, the resin engaging piece, which is positioned between the metal engaging piece and the facing piece and engages with it, is sandwiched between the bent facing piece and the metal engaging piece, allowing the resin engaging piece and the metal engaging piece to abut more reliably. Even if the resin frame material deforms due to temperature changes, the abutting state between the resin engaging piece and the metal engaging piece is maintained. This makes it possible to provide a fixture with even better watertightness.

[0038] Such building fixtures are characterized in that the metal frame material has a recessed wall portion with a recessed surface on which a shoji screen is supported so that it can be opened and closed freely, the resin frame material has a protruding portion that protrudes further toward the inner periphery of the frame body than the recessed wall portion and forms a door stop for the shoji screen, the metal engaging piece and the resin engaging piece are provided on the outer periphery of the frame body than the recessed wall portion, and the metal frame material has a protruding piece on the outdoor side of the protruding portion that protrudes toward the inner periphery of the frame body along the protruding portion.

[0039] According to this type of fitting, the metal frame has a protruding piece that protrudes inward along the protruding portion on the outdoor side of the protruding portion that protrudes inward from the projecting wall portion of the metal frame, so that rainwater and other water that penetrates between the shoji screen and the metal frame is blocked by the protruding piece and is less likely to penetrate directly into the protruding portion. Furthermore, since the protruding piece is located along the protruding portion further inward than the projecting wall portion located on the inner periphery of the metal engaging piece and the resin engaging piece, even if rainwater and other water penetrates between the shoji screen and the metal frame, it is prevented from passing between the protruding piece and the protruding piece and penetrating into the metal engaging piece and the resin engaging piece. This makes it possible to provide fittings with even better water-tightness. [Explanation of symbols]
