Modes for Carrying Out the Invention
[0009] Hereinafter, embodiments of the fitting according to the present invention will be described in detail with reference to the drawings. Note that the present invention is not limited by this embodiment.
[0010] Hereinafter, for convenience, the terms "expected direction" and "finding direction" may be used. The expected direction is the direction along the depth of the fitting. A surface or wall along the expected direction may be referred to as an expected surface or an expected wall. The finding direction is the direction along the vertical, orthogonal to the expected direction, in the case of something extending along the horizontal direction such as a lower frame. In the case of something extending along the vertical direction such as a vertical frame, the finding direction is the direction along the horizontal, orthogonal to the expected direction. A surface or wall along the finding direction may be referred to as a finding surface or a finding wall.
[0011] FIG. 1 is a longitudinal sectional view of a fitting 10 according to an embodiment of the present invention. FIG. 2 is a cross-sectional view of the fitting 10. The fitting 10 is a vertically sliding window that holds a shoji 14 on the inner peripheral side of a frame body 12 and slides the shoji 14 out to the outdoor side along a rail to open it.
[0012] The shoji 14 is configured by disposing a panel 24 inside a frame body 22 formed by surrounding a lower frame 16, an upper frame 18, and left and right vertical frames 20. In the present application, a molding that holds the edge of the panel is a frame member in a broad sense. Therefore, the lower frame 16, the upper frame 18, and the vertical frames 20 are frame members in a broad sense, and the frame body 22 is a frame member in a broad sense. The frame body 12 is configured by surrounding a lower frame 26, an upper frame 28, and left and right vertical frames 30. Each frame member and each frame material are composite materials in which a metal such as an aluminum alloy and an extruded molding of a resin material are combined, and are configured to have a substantially uniform cross-sectional shape over the entire length along the longitudinal direction. The same applies to the fitting 10A described later.
[0013] The lower frame 26 is composed of a metal lower frame 26a mainly forming the outer peripheral side and the outdoor side, and a resin lower frame 26b mainly forming the inner peripheral side and the indoor side. The resin lower frame 26b may constitute a part of the floor surface. The upper frame 28 is composed of a metal upper frame 28a mainly forming the outer peripheral side and the outdoor side, and a resin upper frame 28b mainly forming the inner peripheral side and the indoor side. The left and right vertical frames 30 basically have a bilaterally symmetric structure. The vertical frame 30 is composed of a metal vertical frame 30a mainly forming the outer peripheral side and the outdoor side, and a resin vertical frame 30b mainly forming the inner peripheral side and the indoor side. Thus, the frame body 12 is a metal-resin composite window frame. A hollow part is provided between each metal frame and each resin frame to provide heat insulation. Each resin frame functions as a decorative frame. In this embodiment, the metal upper frame 28a and the metal vertical frame 30a have the same shape except for details such as screw holes and some dimensions. In this embodiment, the resin upper frame 28b and the resin vertical frame 30b have the same shape except for finding dimensions and the like. The expected dimensions of each resin frame are the same.
[0014] The lower frame 16 and the upper frame 18 basically have an up-down symmetric structure. The left and right vertical frames 20 basically have a bilaterally symmetric structure. Between the lower frame 16 and the lower frame 26, between the upper frame 18 and the upper frame 28, and between the vertical frame 20 and the vertical frame 30, a seal 31 is provided in the gap in the expected direction. Between the lower frame 16 and the lower frame 26, and between the upper frame 18 and the upper frame 28, a link mechanism 32 for a sliding-out function is provided in the gap in the finding direction. A pulling member 34 is provided between the left vertical frame 20 and the vertical frame 30 in FIG. 2. Since the vertically sliding window is not directly connected by a hinge, when closed, the sliding door is pulled toward the indoor side by the pulling member 34 using the inclination. A handle 36 is provided on the right vertical frame 20 in FIG. 2, which engages and disengages with the latch member of the vertical frame 30 to open and close the sliding door 14. In this embodiment, the panel 24 is a multilayer glass.
[0015] The lower frame 16 will be described. Since the upper frame 18 is symmetric with the lower frame 16 about the up-down direction, the same reference numerals are given and the detailed description is omitted. Also, the left and right vertical frames 20 only differ from the lower frame 16 in the shape and finding width of the indoor-side hollow part 42c described later, and the detailed description is omitted.
[0016] Figure 3 is a longitudinal sectional view of the lower frame 16. Figure 4 is a longitudinal sectional view of the pressing edge 40. The lower frame 16 has a metal frame 38 and a pressing edge 40. Among these, the pressing edge 40 is composed of a metal pressing edge 50 and a resin pressing edge 52, and the lower frame 16 is a metal-resin composite frame. The pressing edge 40 is also provided on the upper frame 18 and the vertical frame 20. In Figure 4, the pressing edge 40 is shown in the same direction as Figure 2 where it is attached to the vertical frame 20. For the part where the pressing edge 40 is provided on the vertical frame 20, an end cover 80 is provided at the upper end.
[0017] The metal frame 38 has a prospective part 42 provided along the prospective direction on the outer peripheral side of the edge of the panel 24 as a base. On the outdoor side, an inner peripheral side outdoor finding piece 44a protruding inward and an outer peripheral side outdoor finding piece 44b protruding outward are provided. The inner peripheral side outdoor finding piece 44a and the outer peripheral side outdoor finding piece 44b form a continuous finding surface. A pocket 44c is provided at the indoor side end of the inner peripheral side outdoor finding piece 44a. A seal 46a and a backup material 46b are provided between the pocket 44c and the outdoor side lower edge part of the panel 24. Seal means other than the seal 46a may be provided in the pocket 44c. The seal 46a and the backup material 46b are provided across the four circumferences on the outdoor side and the indoor side of the panel 24.
[0018] The prospective part 42 has an outdoor side hollow part 42a, a central hollow part 42b, and an indoor side hollow part 42c formed side by side in the prospective direction. Bore holes 48 are provided in the central hollow part 42b and the indoor side hollow part 42c. The outdoor side hollow part 42a is substantially square and is almost entirely on the outdoor side of the panel 24. Half of the central hollow part 42b on the outdoor side has the same finding width as the outdoor side hollow part 42a, and the width of the half on the indoor side is slightly smaller. In the central hollow part 42b, a prospective piece 42d protrudes slightly inward at the central step part, forming a groove-shaped pressing edge mounting base 42e. A part of the central hollow part 42b extends indoors from the panel 24.
[0019] The indoor-side hollow portion 42c is further on the indoor side than the central hollow portion 42b, and has a larger finding width than the outdoor-side half of the central hollow portion 42b and the outdoor-side hollow portion 42a. In this embodiment, the prospective width of the indoor-side hollow portion 42c is about 2 / 3 of that of the central hollow portion 42b. A rectangular depression 42f is formed in the inner peripheral side portion at the indoor-side end of the indoor-side hollow portion 42c. The indoor-side finding wall 38a of the metal frame 38 forms the entire indoor-side surface of the indoor-side hollow portion 42c and the indoor-side wall of approximately half of the finding width in the depression 42f. A claw 38b protruding outward is provided at the inner peripheral side end of the indoor-side finding wall 38a. The inner peripheral side prospective surface of the indoor-side hollow portion 42c protrudes slightly outward to form a pressing-edge engaging protrusion 42g.
[0020] Between the outdoor-side finding wall 42h of the indoor-side hollow portion 42c and the indoor-side approximate half prospective wall 42i of the central hollow portion 42b, a prospective piece 42d and the pressing-edge engaging protrusion 42g protruding on the inner peripheral side form an engaging piece accommodating groove 42j. The engaging piece accommodating groove 42j is a portion where the outer peripheral engaging piece 50c, the prospective piece 50d, and the gentle bending portion 50f described later are accommodated. The engaging piece accommodating groove 42j is slightly longer in the prospective direction. The outdoor-side prospective piece 42d is slightly on the outer peripheral side of the outdoor-side pressing-edge engaging protrusion 42g. The prospective piece 42d is on the outdoor side of the indoor-side surface of the panel 24, and the pressing-edge engaging protrusion 42g is on the indoor side.
[0021] The pressing edge 40 includes an outdoor-side metal pressing edge 50 and an indoor-side resin pressing edge 52. The metal pressing edge 50 is an extruded profile formed of a metal such as an aluminum alloy, and has a panel support piece 50a, an inner peripheral engaging portion 50b, and an outer peripheral engaging piece 50c. The panel support piece 50a extends along the finding direction. Two metal meshing portions 54, 56 and a protruding piece 50e are provided on the finding surface facing the indoor side of the panel support piece 50a. There is a gap 50g between the metal meshing portion 54 and the metal meshing portion 56. A shallow depression 57 is formed on the outdoor side of the panel support piece 50a on the side opposite to the gap 50g. The inner peripheral side wall of the depression 57 forms a resin meshing portion 62 described later.
[0022] The metal engaging portions 54 and 56 are arranged in the finding direction, with the metal engaging portion 54 on the outer peripheral side and the metal engaging portion 56 on the inner peripheral side. The metal engaging portion 54 has an L shape and includes a bent base portion 54a that projects short inward from the panel support piece 50a and a bent portion 54b whose tip is bent toward the outer peripheral side. The metal engaging portion 56 has a square U shape and is bent short in three steps from the tip of the panel support piece 50a inward, toward the inner peripheral side, and toward the outer side.
[0023] The protruding piece 50e projects inward from a portion on the outer peripheral side of the panel support piece 50a that is more outer peripheral than the metal engaging portion 54.
[0024] The inner peripheral engaging portion 50b extends outward from the edge on the outer peripheral side of the panel support piece 50a and then curves toward the outer peripheral side to form a groove 50ba that opens inward. A portion of the edge of the panel support piece 50a slightly protrudes on the inner peripheral side of this groove 50ba. The push-edge engaging protrusion 42g is inserted and engaged from the inner side into the groove 50ba, and the metal push-edge 50 is engaged with the metal frame 38.
[0025] The outer peripheral engaging piece 50c extends obliquely outward from the edge on the outer peripheral side of the inner peripheral engaging portion 50b and then bends to form a prospective piece 50d that extends in the prospective direction outward. The outer edge of the prospective piece 50d forms a gently bent portion 50f that bends slightly inward. The gently bent portion 50f of the prospective piece 50d is part of the outer peripheral engaging piece 50c. The prospective piece 50d is in contact with the inner peripheral side wall of the central hollow portion 42b. The gently bent portion 50f fits into the push-edge mounting base 42e and abuts against the outer peripheral surface with respect to the prospective piece 42d.
[0026] The resin push-edge 52 is an extruded shape formed of resin and has a hollow portion 58 and two resin engaging portions 60 and 62. The hollow portion 58 is substantially square and is partitioned by a partition 58a into an inner peripheral side air chamber 58b and an outer peripheral side air chamber 58c of the same shape. By partitioning the hollow portion 58 into two air chambers, the heat insulation and strength are improved.
[0027] The resin engagement portions 60 and 62 are arranged in the finding direction, with the resin engagement portion 60 on the outer peripheral side and the resin engagement portion 62 on the inner peripheral side. The resin engagement portion 60 has an L shape and includes a bent base portion 60a that projects short from the panel support piece 50a to the outdoor side, and a bent portion 60b whose tip is bent to the inner peripheral side. The resin engagement portion 62 has a square U shape, and the inner peripheral side wall of the hollow portion 58 extends to the outdoor side and is bent short in two steps from its tip to the outer peripheral side and the indoor side, respectively.
[0028] The bent portion 54b of the metal engagement portion 54 has the same length in the finding direction as the bent portion 60b of the resin engagement portion 60, and the L-shaped metal engagement portion 54 and the resin engagement portion 60 are engaged with each other with almost no gap.
[0029] The square U-shaped metal engagement portion 56 and the resin engagement portion 62 are engaged with each other, but a slight gap is secured so as not to affect the engagement between the metal engagement portion 54 and the resin engagement portion 60. Between the metal engagement portion 56 and the resin engagement portion 62, and between the metal engagement portion 54 and the resin engagement portion 60, the metal pressing edge 50 and the resin pressing edge 52 are engaged by sliding them in the longitudinal direction.
[0030] The indoor-side finding wall 52a of the resin pressing edge 52 projects to the outer peripheral side of the hollow portion 58 and covers approximately the inner peripheral side half of the recess 42f. An engaging portion 52b is provided at the tip of the indoor-side finding wall 52a. The engaging portion 52b extends further to the outer peripheral side via a stepped portion 52c that is slightly shifted to the outdoor side from the tip of the indoor-side finding wall 52a, and a claw 52d that projects to the inner peripheral side is provided at the outer peripheral side tip. The engaging portion 52b engages with the metal frame 38 when the claw 52d engages with the claw 38b. That is, the resin pressing edge 52 engages with the indoor-side finding wall 38a of the metal frame 38 on the outdoor side. Since the stepped portion 52c is formed in the engaging portion 52b, the indoor-side finding walls 38a and 52a form a continuously planar indoor-side finding surface, which is aesthetically suitable and facilitates guiding condensed water and the like downward.
[0031] The expected dimension L1 of the hollow portion 58 is wide enough to accommodate the internal mechanism of the handle 36 (see FIG. 2). The expected width of the resin edge 52 including the resin engagement portions 60 and 62 is about the same as that of the indoor-side hollow portion 42c. The found dimension L2 of the hollow portion 58 is suppressed to a sufficient extent to form the resin engagement portions 60 and 62. Relatively, the area of the panel 24 is large and the lower frame 16 is narrow, which is aesthetically suitable and improves the heat insulation performance.
[0032] As shown in FIG. 3, a seal 46a and a backup material 46b are provided between the outdoor-side surface of the edge 40 and the indoor-side lower edge portion of the panel 24. That is, the edge of the panel 24 is held by the outdoor-side found piece 44a on the inner peripheral side of the metal frame 38 and the edge 40 on the indoor side. The lower frame 16 has a panel opening 70 that opens to the inner peripheral side by the outdoor-side found piece 44a on the inner peripheral side and the edge 40, and the panel 24 is supported by a setting block 72 within the panel opening 70.
[0033] FIG. 5 is a cross-sectional view of the vertical frame 20. The handle 36 is omitted in FIG. 5. The vertical frame 20 has a metal frame 39 and an edge 40. The indoor-side found wall 39a, claw 39b, expected portion 43, outdoor-side hollow portion 43a, indoor-side hollow portion 43c, expected piece 43d, edge mounting base 43e, edge engagement projection 43g, outdoor-side found wall 43h, expected wall 43i, engagement piece accommodation groove 43j, inner peripheral-side outdoor found piece 45a, outer peripheral-side outdoor found piece 45b, and pocket 45c in the metal frame 39 correspond to the indoor-side found wall 38a, claw 38b, expected portion 42, outdoor-side hollow portion 42a, indoor-side hollow portion 42c, expected piece 42d, edge mounting base 42e, edge engagement projection 42g, outdoor-side found wall 42h, expected wall 42i, engagement piece accommodation groove 42j, inner peripheral-side outdoor found piece 44a, outer peripheral-side outdoor found piece 44b, and pocket 44c in the metal frame 38.
[0034] The metal frame 39 does not have the central hollow portion 42b in the metal frame 38, and the outdoor-side hollow portion 43a and the indoor-side hollow portion 43c are separated from each other. However, the outdoor-side hollow portion 43a is ensured to be longer in the prospective direction than the outdoor-side hollow portion 42a, and extends to a position slightly on the indoor side from the middle of the panel 24 in the prospective direction and up to the position of the edge mounting base portion 43e. A pocket 43k is provided on the inner peripheral side of the outdoor-side hollow portion 43a. The prospective piece 43d protrudes from the indoor side of the pocket 43k. As described above, an end cover 80 is provided at the upper end of the edge 40 in the vertical frame 20.
[0035] FIG. 6 is a schematic diagram showing a state of mounting the edge 40 on the metal frame 39. When mounting the edge 40 on the metal frame 39, the panel 24 is set in the panel opening 70, and the shoji 14 is kept closed with respect to the frame body 12. At this stage, the seal 46a and the backup material 46b are not provided on the indoor side of the panel 24.
[0036] When mounting the edge 40 on the metal frame 39, the edge 40 is inclined and the gentle bending portion 50f is inserted into the edge mounting base portion 43e. With this portion as a base point, the indoor side, that is, the resin edge 52 portion, is pressed so as to draw a rotation locus as shown by the arrow in FIG. 6. As a result, on the outdoor side, the inner peripheral engagement portion 50b and the edge engagement protrusion 43g are engaged, and on the indoor side, the engagement portion 52b and the claw 52d are engaged to stabilize the edge 40. Also, the engagement between the prospective piece 43d and the gentle bending portion 50f also contributes to stable engagement. After mounting the edge 40, the seal 46a and the backup material 46b may be provided between the edge 40 and the panel 24. Thus, the edge 40 can be easily mounted at the construction site.
[0037] The engaging portion 52b is configured to engage with the indoor-side finding wall 39a on the outdoor side, and the claw 52d protrudes toward the indoor side. When engaging with the claw 39b of the metal frame 39, it is temporarily displaced slightly toward the outdoor side, but it does not displace toward the indoor side and will not contact or damage the seal 31, the resin vertical frame 30b, etc. When the claw 52d of the engaging portion 52b engages with the claw 39b, the resin pressing edge 52 receives a force that temporarily rotates counterclockwise in FIG. 6 around the vicinity of the inner peripheral engaging portion 50b, but it does not rotate counterclockwise and there is no interference with the panel 24.
[0038] In the structure of the pressing edge 40, when an external force that presses the panel 24 toward the indoor side acts due to the outdoor wind pressure (positive pressure), the panel support piece 50a of the metal pressing edge 50 moves toward the indoor side via the inner peripheral engaging portion 50b. In this case, the movement of the panel support piece 50a toward the indoor side is restricted by the fact that the gently bent portion 50f of the metal pressing edge 50 contacts the prospective piece 43d provided on the metal frame 39, and the situation where the pressing edge 40 falls off from the metal frame 39 can be prevented. In addition, when the panel support piece 50a moves toward the indoor side, the movement of the resin pressing edge 52 is restricted because the engaging portion 52b provided on the resin pressing edge 52 contacts the indoor-side finding wall 39a. As a result, the situation where the panel support piece 50a moves toward the indoor side via the resin pressing edge 52 is restricted, and the falling off of the pressing edge 40 is more reliably prevented.
[0039] On the other hand, when an external force that pulls the panel 24 toward the outdoor side acts due to the outdoor wind pressure (negative pressure), the panel support piece 50a of the metal pressing edge 50 moves toward the outdoor side via the inner peripheral engaging portion 50b. In this case, the movement of the panel support piece 50a toward the outdoor side is restricted by the fact that the gently bent portion 50f of the metal pressing edge 50 contacts and is supported by the prospective surface on the inner peripheral side of the prospective portion 43, and the situation where the pressing edge 40 falls off from the metal frame 39 can be prevented.
[0040] Next, the end cover 80 will be described. The end cover 80 is fixed to the metal pressing edges 50 on the left and right vertical frames 20 and covers the finding surface of the upper end portion of the resin pressing edge 52 or the corresponding extended portion thereof. Specifically, when the resin pressing edge 52 is not shrunk, it covers the upper end portion thereof, and when the resin pressing edge 52 is shrunk, it covers the portion on the finding side of the gap 82 (see FIG. 10), which is the corresponding extended portion.
[0041] FIG. 7 is a perspective view of the end cover 80 as viewed from the indoor side. FIG. 8 is a perspective view of the upper end portion of the vertical frame 20 as viewed from the obliquely upper side on the outdoor side. FIG. 9 is a perspective view of one vertical frame 20 of the fixture 10 as viewed from the obliquely lower side on the outdoor side. In FIG. 9, a part is shown in a cutout state, and the panel 24, the seal 46a, and the backup material 46b are indicated by phantom lines. FIG. 10 is a view of the end cover 80 and its peripheral portion as viewed from the outdoor side.
[0042] As shown in FIG. 10, the frame body 12 is vertically dominant, and the lower edge of the upper frame 28 abuts against the side surface of the vertical frame 30. The frame body 22 is vertically dominant, and the lower edge of the upper frame 18 abuts against the side surface of the vertical frame 20. Similarly, the metal frame 38 (first metal frame) of the vertical frame 20 intersects so as to be dominant over the metal frame 38 (second metal frame) of the upper frame 18. In the case of a horizontally dominant configuration, the end cover 80 may be provided at the ends of the lower frame 16 and the upper frame 18.
[0043] As shown in FIGS. 7 and 8, the end cover 80 has an L-shaped configuration including a vertically extending fixing piece 80a and a cover piece 80b protruding from the upper end of the fixing piece 80a. The vertical length of the fixing piece 80a and the horizontal length of the cover piece 80b are approximately the same. The left-right width of the fixing piece 80a is slightly larger than the up-down width of the cover piece 80b. A fastening piece 80c protrudes from the central portion of the fixing piece 80a toward the indoor side. The tip of the cylindrical portion of the fastening piece 80c has a dovetail shape and is divided vertically. On the indoor side of the fixing piece 80a, a low wall 80d is provided along the upper, lower, and the protruding side of the cover piece 80b (the left side in FIG. 7). Regarding the opposite side where the cover piece 80b protrudes (the right side in FIG. 7), the upper and lower portions of the wall 80d and the vertical edge of the fixing piece 80a are slightly separated. The end cover 80 is formed of a resin material.
[0044] As shown in FIGS. 8 and 4, near the upper end of the panel support piece 50a in the metal edge trim 50, a cover mounting hole 50h is formed in the prospective direction. The cover mounting hole 50h penetrates up to the gap 50g. The fastening piece 80c is inserted into the cover mounting hole 50h, and the dovetail portion at the tip enters the gap 50g to engage, thereby fixing the end cover 80 to the metal edge trim 50.
[0045] Refer to FIGS. 9, 10, and 4. The fixing piece 80a extends vertically along the metal edge trim 50. The resin edge trim 52 has a resin meshing portion 62 exposed to the outdoor side. The cover piece 80b protrudes from the upper end of the fixing piece 80a and covers the entire length in the prospective direction of the upper end of the resin meshing portion 62, which is the exposed portion of the resin edge trim 52. That is, the inner peripheral side end portions of the cover piece 80b and the resin meshing portion 62 are aligned. Also, at normal temperature, the upper surfaces of the metal edge trim 50, the resin edge trim 52, and the end cover 80 are aligned. The upper opening of the recess 57 is blocked by the wall 80d.
[0046] The end cover 80 is fixed to the outdoor-side finding surface of the metal edge trim 50. Since the cover piece 80b covers only the upper-end finding surface of the resin edge trim 52 from the outdoor side, it cannot be visually recognized from the indoor side. The end cover 80 is located at the panel opening 70 and cannot be visually recognized from the outdoor side either. The end cover 80 is in an L shape and is arranged along the corner of the panel 24 indicated by the phantom line in Fig. 9, and does not interfere with the four-sided seals 46a and backup materials 46b.
[0047] The protruding piece 50e of the metal edge trim 50 and the bent base 60a of the resin edge trim 52 are fixed to each other by screwing or caulking at the fixing location 68 (see Fig. 9) near the lower end, and even if the resin edge trim 52 expands and contracts in the longitudinal direction (in this case, the vertical direction) due to temperature, it will not detach from the metal edge trim 50. Since the fixing location 68 is near the lower end of the edge trim 40, the metal edge trim 50 and the resin edge trim 52 will not be displaced in this vicinity.
[0048] On the other hand, at low temperatures, the metal edge trim 50 hardly contracts, but the resin edge trim 52 contracts to a certain extent. Then, at the upper end of the edge trim 40, as shown by the phantom line in Fig. 10, a gap 82 may occur between the resin edge trim 52, which becomes lower, and the abutting object with a small opening (in this case, the upper frame 28). However, since the end cover 80 is fixed to the non-contracting metal edge trim 50, its position is maintained, and since the cover piece 80b covers the space between the end of the resin edge trim 52 and the abutting object, the gap 82 can be properly blocked to maintain the watertight and airtight states. In Fig. 10, the gap 82 is indicated by a dotted pattern. The gap 82 is regarded as the equivalent extension part of the resin edge trim 52.
[0049] By providing the end cover 80 at the upper end of the edge trim 40, only one fixing location 68 at the lower end is sufficient. Although the fixing location 68 may be provided near the upper end and the end cover 80 may be provided at the lower end, since it is desirable that the lower end has a simpler structure from the viewpoint of waterproof performance, it is desirable to provide the end cover 80 at the upper end. Depending on the conditions, the end cover 80 may be provided at both the upper and lower ends.
[0050] In order to meet requirements such as fixing strength, a plurality of fixing points 68 may be provided near the lower end, or they may be provided at a location somewhat away from the lower end. However, if the end cover 80 is provided only at the upper end, it is preferable that the fixing points 68 are fixed to each other only in the range below the center C where the upper and lower lengths are H1 out of the total length H in the longitudinal direction of the vertical frame 20 between the metal edge pressing member 50 and the resin edge pressing member 52. However, depending on the conditions, the end cover 80 may be provided at both the upper and lower ends.
[0051] The edge pressing member 40, the attachment of the end cover 80, and the treatment of the fixing points 68 can basically be carried out by the manufacturer of the fitting 10. At the construction site, the edge pressing member 40 can be treated as substantially one member. Therefore, the number of substantial parts to be handled at the construction site is suppressed, and the construction becomes easy.
[0052] FIG. 11 is a longitudinal sectional view of a fitting 10A according to another embodiment. FIG. 12 is a cross-sectional view of the fitting 10A. The fitting 10A is a FIX window including a frame body 186 formed by surrounding a lower frame 180, an upper frame 182, and left and right vertical frames 184, and a panel 24 such as a multilayer glass disposed inside the frame body 186. In the FIX window, the panel 24 is held on the inner peripheral side of the frame body 186 and is fixedly installed so as not to be opened or closed.
[0053] The lower frame 180 is mainly composed of a metal lower frame 180a that constitutes the outer peripheral side and the outdoor side, and a resin lower frame 180b that constitutes the inner peripheral side and the indoor side. The upper frame 182 is mainly composed of a metal upper frame 182a that constitutes the outer peripheral side and the outdoor side, and a resin upper frame 182b that constitutes the inner peripheral side and the indoor side. The left and right vertical frames 184 basically have a bilaterally symmetric structure. The vertical frame 184 is mainly composed of a metal vertical frame 188 that constitutes the outer peripheral side and the outdoor side, and a resin vertical frame 190 that constitutes the inner peripheral side and the indoor side. A hollow portion is provided between each metal frame and each resin frame to provide heat insulation.
[0054] As shown in FIG. 12, a pressing edge 40 is attached to the vertical frame 184. The pressing edge 40 is the same as that in the above-mentioned fitting 10. The panel 24 is held between the outdoor finding piece 188a on the inner peripheral side of the metal vertical frame 188 and the pressing edge 40 via a seal 46a and a backup material 46b. The metal vertical frame 188 has a prospective piece 42d, a pressing edge engaging protrusion 42g, and an engaging piece accommodating groove 42j similar to those of the above-mentioned metal frame 38, and accommodates and holds the outer peripheral engaging piece 50c of the metal pressing edge 38.
[0055] The metal vertical frame 188 extends longer on the indoor side than the above-mentioned metal frame 38. The intermediate finding wall 188b in the middle of the prospective direction in the metal vertical frame 188 corresponds to the above-mentioned outdoor finding wall 42h, and a pressing edge engaging protrusion 42g is provided at the inner peripheral end portion toward the outdoor side. A first resin engaging portion 188c is provided on the indoor side surface of the intermediate finding wall 188b. The first resin engaging portion 188c is composed of a small protrusion 188ca and an L-shaped protrusion 188cb. The L-shaped protrusion 188cb is in an L-shaped bent toward the inner peripheral side. The tips of the small protrusion 188ca and the L-shaped protrusion 188cb form a narrow opening.
[0056] A second resin engaging portion 188d is provided at the indoor side end portion of the metal vertical frame 188. The second resin engaging portion 188d has a protruding piece 188da facing the inner peripheral side and an L-shaped protrusion 188db. The L-shaped protrusion 188db protrudes slightly toward the indoor side from the end portion of the protruding piece 188da, and then protrudes by the same amount as the protruding piece 188da toward the inner peripheral side. A small bulging portion 188dc is formed at the middle portion of the protruding piece 188da.
[0057] The resin vertical frame 190 is a member long in the prospective direction. A thin rectangular hollow portion 190a serves as a base, and it has a first protruding wall 190b whose outer peripheral wall extends toward the outdoor side, a second protruding wall 190c whose inner side wall extends toward the outer peripheral side, and a third protruding wall 190d whose inner peripheral wall extends toward the indoor side.
[0058] At the tip of the first protruding wall 190b, a first metal engaging portion 190e bent outward in the outer peripheral direction is provided. The first metal engaging portion 190e enters the opening of the first resin engaging portion 188c, and the outer peripheral claws are fitted and fixed between the small protrusion 188ca and the base end portion of the L-shaped protrusion 188cb. At the tip of the second protruding wall 190c, a second metal engaging portion 190f bent in a crank shape is provided. The second metal engaging portion 190f enters the opening of the second resin engaging portion 188d, and the two outer peripheral claws engage with each other so as to sandwich the bulging portion 188dc. Further, the crank-shaped bent portion of the second metal engaging portion 190f abuts against the end portion of the L-shaped protrusion 188cb and is stabilized. In this way, the resin vertical frame 190 is firmly fixed to the metal vertical frame 188.
[0059] An engaging protrusion 190g protrudes from the outdoor side surface of the hollow portion 190a and engages with the claw 52d of the engaging portion 52b in the same manner as the claw 38b described above. That is, although the object to be engaged by the engaging portion 52b of the pressing edge 40 is not a metal material, the resin vertical frame 190 is firmly fixed to the metal vertical frame 188 and has the same function as the fitting 10. An end cover 80 is provided at the upper end of the pressing edge 40 of the vertical frame 20 in the fitting 10A, and has the same function as described above. In this case, the edge of the pressing edge 40 and the object to be contacted by the end cover 80 in the vertical frame 20 are the upper frame 182 or the expected surface of the housing (not shown).
[0060] The present invention is not limited to the above-described embodiments, and it goes without saying that it can be freely changed without departing from the gist of the present invention.
[0061] The fitting according to the present invention is a fitting that holds the edge of a panel by an outdoor finding piece of a metal frame and an indoor pressing edge, and the pressing edge includes a metal pressing edge, a resin pressing edge, and an end cover fixed to the metal pressing edge and covering between the end of the resin pressing edge and the object to be contacted by the edge of the pressing edge.
[0062] In such a fitting, the attachment process of the edge trim to the end cover can basically be performed by the manufacturer. At the construction site, the edge trim can be treated as substantially one member. Therefore, the number of actual parts to be handled at the construction site is reduced, and the construction becomes easier.
[0063] The end cover may be fixed to the outdoor-facing surface of the metal edge trim and cover only the end of the resin edge trim from the outdoor side. In this way, the end cover is at least not visible from the indoor side. Also, this location is usually inside the panel opening and is not visible from the outdoor side either.
[0064] The metal edge trim and the resin edge trim are fixed to each other only on one side of the longitudinal center, and the end cover may be provided at the other end from the longitudinal center. As a result, basically, only the other end is where the resin edge trim shrinks and a gap is generated, and it is sufficient to cover only this part with the end cover.
[0065] The metal frame is a vertical frame, and the end cover may be provided at the upper end of the edge trim. In this way, it is preferable to provide the end cover at the upper part, avoiding the lower part where water drips.
[0066] The metal frame may intersect such that the first metal frame wins over the second metal frame and is provided to abut against the prospective inner peripheral surface of the abutting object of the narrow end of the edge trim. Thereby, the gap between the abutting object can be appropriately blocked by the end cover.
[0067] The metal frame has an edge trim engaging projection at a portion on the indoor side of the panel, and the metal edge trim may have an inner peripheral engaging portion that engages with the edge trim engaging projection and an outer peripheral engaging piece that engages with the metal frame at a position on the outdoor side and the outer peripheral side of the edge trim engaging projection. Thereby, suitable wind pressure resistance performance can be obtained.
[0068] If the outer peripheral engaging piece is hung on the outer peripheral surface with respect to the prospective piece protruding toward the indoor side formed on the metal frame, it can be mounted so as to draw a rotation locus with reference to this portion.
[0069] Seals are provided at the four peripheral edges on the indoor side of the panel. The end cover has an L shape including a fixing piece along the metal edge pressing part and a cover piece protruding from the end of the fixing piece to cover the end of the resin edge pressing part, and may be non-interfering with the seal.
