Description

[Technical Field]

[0001] The present invention relates to an end cover that is provided at the end of a profile in a building fixture. [Background technology]

[0002] Edge covers are sometimes provided on the ends of shaped members in building fixtures. The edge covers described in Patent Document 1 are fixed to the shaped members with screws. The edge covers may be fixed to the building walls with a fixing agent such as a sealant. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2001-288965 Summary of the Invention [Problem to be solved by the invention]

[0004] The profile may expand and contract due to heat, which can cause the end covers to displace as well, placing stress on the wall and the fixing material, potentially shortening its lifespan.

[0005] The present invention has been made in consideration of the above-mentioned problems, and has an object to provide an edge cover that can absorb thermal expansion and contraction of a profile. [Means for solving the problem]

[0006] In order to solve the above-mentioned problems and achieve the object, the end cover of the present invention is an end cover that is provided on the end of a shaped member in a building fixture, and comprises: an end wall that covers the end of the plate-shaped portion of the shaped member; a first retaining portion that protrudes from the end wall in the extension direction of the shaped member and faces a first surface of the plate-shaped portion; a second retaining portion that protrudes from the end wall in the extension direction of the shaped member and abuts against a second surface side opposite the first surface to hold the plate-shaped portion; a first elastic material that is provided on the first retaining portion and elastically abuts against the first surface to hold it; and a second elastic material that is provided between the end and the end wall, and the shaped member is a water-draining member that receives water flowing in from the bottom frame of the building fixture and directs it to the outside of the room, and the first surface is the upper surface. [Effects of the Invention]

[0007] Since the edge cover of the present invention is not fixed to the profile, it can absorb the thermal expansion and contraction of the profile. [Brief explanation of the drawings]

[0009] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a fore-edge cover according to the present invention will be described in detail below with reference to the accompanying drawings. However, the present invention is not limited to this embodiment.

[0010] For convenience, the terms "visible direction" and "visible wall" may be used below. The visible direction (the direction indicated by arrow Z in the figure) is the indoor / outdoor direction along the depth of the door / window 12. Surfaces and walls along the visible direction may be referred to as "visible surface" or "visible wall." The visible direction is the direction perpendicular to the visible direction (the direction indicated by arrow Y in the figure) for elements that extend horizontally, such as upper frames, lower frames, upper stiles, and lower stiles, and is the direction perpendicular to the visible direction (the direction indicated by arrow X in the figure) for elements that extend vertically, such as vertical frames and vertical stiles. Surfaces and walls along the visible direction may be referred to as "visible surface" or "visible wall."

[0011] 1 is a partially cross-sectional perspective view of a drainage structure 10 and a fitting 12 to which the drainage structure 10 is applied, viewed obliquely from the outside of the room. The drainage structure 10 has an end cover 10b and a cap 10c according to an embodiment of the present invention, and further includes a drainage member 10a. The drainage structure 10 and the fitting 12 in this example are bilaterally symmetrical, and FIG. 1 shows only the left portion as viewed from the outside of the room.

[0012] The fitting 12 has a frame 14 fixed to an opening in the wall of a building, and a panel 16 (see Figure 2) attached to the inner periphery of the frame 14. The fitting 12 in this embodiment is a fixed window, but it may also be a hinged door, a sliding window, etc. The panel 16 in this embodiment is double-glazed.

[0013] The frame body 14 is constructed by assembling a lower frame 18, an upper frame (not shown), and left and right vertical frames 20 (only one is shown) around all four sides. Each frame material is an extruded shape made of metal such as aluminum alloy or resin, or a composite material thereof, and each is constructed so as to have a substantially uniform cross-sectional shape along its entire length.

[0014] Figure 2 is a vertical cross-sectional view of the drainage structure 10 and the lower frame 18. The lower frame 18 has a main portion 18a consisting of multiple hollow portions, an indoor retaining portion 18b that protrudes upward from the indoor end of the main portion 18a, a convex hollow portion 18c that protrudes from the main portion 18a to the outdoor side, and two frame fixing pieces 18d and 18e. A batten 22 is attached to the outdoor side of the main portion 18a. The edges of the panels 16 are held in place by the batten 22 and the indoor retaining portion 18b. The upper frame and vertical frame 20 hold the panels 16 in the same way.

[0015] The convex hollow portion 18c is a hollow portion that is slightly long and thin in the projection direction, and its upper surface slopes gently downward toward the outside of the room. A drainage component 24 is provided at the outdoor end of the convex hollow portion 18c. Although a detailed explanation of the path will be omitted, water that enters the lower frame 18 is drained through the drainage component 24. The frame fixing piece 18d protrudes downward from the main portion 18a and abuts against the outdoor-facing surface of the frame 26, where it is fixed with screws 28. The frame fixing piece 18e protrudes indoors from the main portion 18a and abuts against the upper surface of the frame 26, where it is fixed with screws 28. Heat insulation material 30 is located below the frame 26.

[0016] A base material 34 is provided on the outdoor side of the main body 26 and the insulation material 30, below the convex hollow portion 18c. The base material 34 is also called an auxiliary truss. The base material 34 has a projected width and height sufficient for driving screws 64, which will be described later. The base material 34 is made of wood, for example. The base material 34 is provided on the upper surface of the insulation material 36. An exterior wall 40 is provided on the outdoor side of the base material 34 and the insulation material 36, with furring strips 38 between them. The presence of the furring strips 38 separates the base material 34 and the exterior wall 40 slightly, forming a ventilation layer. The lower end of the ventilation layer is connected to the outdoors. The upper end of the exterior wall 40 is located slightly higher than the base material 34. In Figure 2, reference numeral 32 denotes a window frame, and the dashed line 41 denotes a waterproof sheet.

[0017] Next, we will explain the drainage member 10a, edge cover 10b, and cap 10c that make up the drainage structure 10. The edge cover 10b and the inclined portion 42 of the drainage structure 10 are slightly inclined, and for convenience, the direction in which they extend is also referred to as the projection direction.

[0018] Fig. 3 is a side view of the drainage structure 10. Fig. 4 is an exploded perspective view of the drainage structure 10. Fig. 5 is a cross-sectional view of the edge cover 10b as seen from the front.

[0019] The water-repellent member 10a and the cover body 70 (see Figure 4) of the end cover 10b (described later) are extruded shapes of metal such as aluminum alloy, and are configured to have a substantially uniform cross-sectional shape along their entire length. Because the water-repellent member 10a and the cover body 70 are made of metal, they are highly strong, have high processing precision, and are weather-resistant. Because the water-repellent member 10a and the cover body 70 protrude further outside the room than the convex hollow portion 18c of the bottom frame 18, metal materials are preferred for their weather-resistant properties. However, resin materials may also be used depending on the conditions. Because the metal water-repellent member 10a protrudes further outside the room and tends to heat up or down more easily than the bottom frame 18, it is desirable to install it so that it does not come into contact with the bottom frame 18.

[0020] The water draining member 10a has an inclined portion 42, a first sight piece 44, a second sight piece 46, a first mounting piece 48, a second mounting piece 50, and a water draining piece 52. The inclined portion 42 extends at an angle so as to receive water flowing in from the convex hollow portion 18c of the lower frame 18 and the drainage component 24 and direct it to the outside of the room, and covers at least the upper part of the outside sight surface 34a of the base material 34. The inclined portion 42 is a plate-like portion. The plate-like portion in this application is not limited to a single plate, but also includes multiple plates stacked and arranged in parallel or approximately parallel positions.

[0021] The first visible piece 44 protrudes downward from the middle of the inclined portion 42. The first visible piece 44 protrudes downward beyond the water draining edge 52a, which is the lower end of the water draining piece 52.

[0022] The first mounting piece 48 and the second mounting piece 50 are mounting portions that are placed on the upper surface 34b of the base material 34. The first mounting piece 48 protrudes slightly from the middle of the first visible piece 44 toward the indoor side.

[0023] The second mounting piece 50 is continuous with the second visible piece 46 and protrudes downward from the indoor end of the inclined portion 42. The upper surface 34b of the base material 34 is basically horizontal, and the second mounting piece 50 protrudes to the same height as the first mounting piece 48.

[0024] A drain hole 56 is formed in the first sight piece 44 at the same height as the first placement piece 48. A drain notch 58 is formed at the lower end of the second sight piece 46. Water that seeps into the space inside the room through the second sight piece 46 is drained by the drain notch 58 into the space between the first sight piece 44 and the second sight piece 46, and is then drained outside the room through the drain hole 56. There are multiple drain holes 56 and multiple drain notches 58.

[0025] The edge cover 10b is provided at both ends of the drain member 10a, but only the left side is shown in each figure when viewed from outside. The edge cover 10b comprises a cover body 70, a tension material (first elastic material) 72, and a heat-expandable elastic material (second elastic material) 74. The cover body 70 is slightly inclined to correspond to the inclined portion 42, but for convenience in explaining the edge cover 10b, the extension direction of the cover body 70 is also referred to as the projection direction. In addition, in the X direction in which the drain member 10a extends, the side of the edge 73 is referred to as the X1 side, and the opposite side is referred to as the X2 side.

[0026] As described above, the cover body 70 is an extruded metal member, and is used by cutting a long piece of material to correspond to the length of the inclined portion 42. The cover body 70 comprises an end wall 76, a first retaining portion 78, and a second retaining portion 80. The end wall 76 is a projecting wall positioned slightly on the X1 side of the end 73 of the drainage member 10a, and protrudes upward from a position slightly below the underside (second surface) 42b of the inclined portion 42, covering the end 73a of the inclined portion 42 from the X1 side. A screw insertion hole 76a is formed in the end wall 76 near the outside end.

[0027] The first retaining portion 78 protrudes from the end wall 76 toward the X2 side and is disposed opposite the upper surface (first surface) 42a of the inclined portion 42, retaining the upper surface 42a via the tapered material 72. The first retaining portion 78 includes an upper wall 78a protruding toward the X2 side from the upper end of the end wall 76, an intermediate wall 78b also protruding from the end wall 76, and an inner wall 78c protruding downward from the end of the upper wall 78a closest to the X2 side. The intermediate wall 78b is crank-shaped with a step 78d in the middle, connecting the intermediate height portion of the end wall 76 with a slightly upper portion of the inner wall 78c.

[0028] A hollow portion 78e is formed by the end wall 76, upper wall 78a, inner wall 78c, and intermediate wall 78b. The X1 side 78ea of ​​hollow portion 78e is separated from the X2 side 78eb by step 78d, with the latter being slightly smaller in both vertical and X-direction width. The lower end of inner wall 78c is near but not in contact with upper surface 42a. The lower portion of intermediate wall 78b on the X2 side of step 78d forms pocket 78f. Pocket 78f is a square C-shape with a downward opening and holds the tape material 72.

[0029] The second retaining portion 80 protrudes in the X2 direction from near the lower end of the edge wall 76 and abuts against the lower surface 42b near the end of the inclined portion 42 to retain it. The second retaining portion 80 protrudes to approximately the same position as the step 78d. In the design standard state, the edge 73a is at intermediate position B of the second retaining portion 80 (see Figure 5). The intermediate wall 78b on the X1 side of the step 78d, the second retaining portion 80, and the edge wall 76 form a space 81 that opens to the X2 side. The second retaining portion 80 has a notch 80a (see Figure 7) into which the first sight piece 44 fits.

[0030] The height H of the first holding portion 78 relative to the upper surface 42a of the inclined portion 42 is, for example, about 15 mm, which prevents water from leaking or splashing in the X1 direction from the inclined portion 42 even in strong winds and rain. The width L of the cover body 70 in the X direction is, for example, about 20 mm, which securely holds the cap 10c, the weatherstretching material 72, and the heat-shrinkable elastic material 74 while providing adequate strength.

[0031] The tension member 72 is provided on the first holding portion 78 and elastically abuts against the upper surface 42a. It includes a held portion 72a, a first elastic arm 72b, and a second elastic arm 72c. The tension member 72 elastically abuts against the upper surface 42a to hold it. The held portion 72a is a T-shaped portion whose top fits into the pocket 78f for support. The first elastic arm 72b is a J-shaped resin elastic member that extends downward from directly below the held portion 72a and curves toward the X1 side. The second elastic arm 72c is a J-shaped resin elastic member that abuts against the lower part of the pocket 78f directly below the held portion 72a, extends in the X2 direction, bends at a right angle, extends downward along the inner wall 78c, and curves toward the X1 side. The first elastic arm 72b is longer than the second elastic arm 72c.

[0032] The elastic arms 72b, 72c have arcuate portions near their tips held by the first holding portion 78 and the second holding portion 80 via the upper surface 42a. At least the first elastic arm 72b, together with the second holding portion 80, clamps the inclined portion 42 to securely hold the waterproof material 72. The tip of the first elastic arm 72b may be in contact with the heat-expanding absorbing elastic material 74. The elastic arms 72b, 72c have a double waterproofing effect against the upper surface 42a of the inclined portion 42.

[0033] There are two heat-expandable absorbing elastic members 74, each cylindrical when uncompressed (see FIG. 4 ) with a projected length of approximately one-quarter of the cover body 70. They are provided at both ends of the cover body 70 in the extension direction, within the space 81 along the extension direction. The heat-expandable absorbing elastic members 74 abut against the end wall 76, the first retaining portion 78, the second retaining portion 80, and the end 73a of the inclined portion 42 in an elastically compressed state. The heat-expandable absorbing elastic member 74 is made of, for example, ethylene propylene diene rubber and has elasticity and weather resistance. One heat-expandable absorbing elastic member 74 may be provided along the entire length of the cover body 70, or three or more may be provided. The heat-expandable absorbing elastic member 74 is simple in shape, inexpensive, and easy to attach to the cover body 70.

[0034] Figure 6 is a perspective view of the cap 10c as viewed obliquely from the interior side of the room. Figure 7 is a perspective view of the water drainage structure 10 as viewed obliquely from below. The cover fitting portion 92 in Figure 7 is a schematic diagram. As shown in Figures 4, 6, and 7, the cap 10c includes a visible wall 82, a box-shaped portion 84, a visible wall 86, a lower end portion 88, an L-shaped portion 90, and the cover fitting portion 92. The visible wall 82 is vertically elongated. The box-shaped portion 84 has a rectangular area extending approximately one-third of the upper part of the room from the visible wall 82. The box-shaped portion 84 covers the visible surface of the cover body 70. The visible wall 86 has a visible width approximately half that of the box-shaped portion 84, and the side of the box-shaped portion 84 on the X1 side extends downward. The lower end portion 88 is connected to the lower ends of the visible wall 82 and the visible wall 86 and covers the lower end of the water drainage piece 52 on the interior side. Both surfaces in the X direction and the top surface of the box-shaped portion 84 are substantially continuous with both surfaces in the X direction and the top surface of the cover main body 70 .

[0035] The L-shaped portion 90 has a projected width and an X-axis width that are approximately half those of the box-shaped portion 84. The X1-side side of the box-shaped portion 84 extends downward for a short distance and then bends at a right angle, extending toward the X2-axis side, facing the bottom of the box-shaped portion 84. Multiple ribs 90a are formed in the X-axis direction on the L-shaped portion 90. The cover fitting portion 92 protrudes from the box-shaped portion 84 toward the interior of the room and includes a side wall 92a, an upper wall 92b, and a lower wall 92c. A screw hole 92d is formed in the center of the side wall 92a. The upper wall 92b extends toward the X2-axis from an upper portion of the side wall 92a. The length of the upper wall 92b in the X-axis direction is equal to the hollow portion 78e (see FIG. 5). The lower wall 92c extends toward the X2-axis from a lower portion of the side wall 92a. The length of the lower wall 92c in the X-axis direction is approximately half the distance between the end wall 76 and the step 78d (see FIG. 5). The cover fitting portion 92 has a plurality of ribs 92e formed in the projection direction.

[0036] Returning to FIG. 4, the tapered material 72 is inserted and housed in the cover body 70 in the forward direction so that the retained portion 72a fits into the pocket 78f. The heat-expandable absorbing elastic material 74 is inserted into the cover body 70 in the forward direction, or inserted and housed between the inner wall 78c and the second retaining portion 80. The cap 10c is inserted in the forward direction so that the cover fitting portion 92 fits into the hollow portion 78e of the cover body 70, and then secured by threading the screw 94 through the screw insertion hole 76a into the screw hole 92d (see FIG. 6). The cap 10c may be secured by a snap fit or other method. The cover fitting portion 92 is stabilized by the upper wall 92b and multiple ribs 92e abutting against the hollow portion 78e with no gaps in the X direction or height direction. The box-shaped portion 84 and the cover body 70 abut with almost no gaps in the forward direction.

[0037] The upper surface of the L-shaped portion 90 and the lower surface of the box-shaped portion 84 sandwich and stabilize the inclined portion 42. The recessed wall 86 covers the small edge 73b of the water separator. The lower end 88 covers the lower end of the water separator 52. Essentially, the fitting and fixing of the water separator 72, the heat-stretchable absorbing elastic material 74, and the cap 10c to the cover body 70 are performed by the manufacturer of the water separator structure 10, allowing for automation and inspection.

[0038] The end cover 10b with the cap 10c is attached to the water-repellent member 10a by a worker at the construction site. To do this, the end cover 10b is inserted into the space 81 slightly below the lower end of the inner wall 78c of the end cover 10b so that it abuts against the upper surface of the second retaining portion 80. The upper surface 42a of the inclined portion 42 of the water-repellent member 10a is elastically biased by the sealing material 72, and the lower surface 42b abuts against the second retaining portion 80. During this insertion process, the upper surface 42a does not come into metal-to-metal contact with the inner wall 78c, so it is not scratched. Furthermore, the elastic arms 72b and 72c slide against the upper surface 42a, but do not scratch it because they have moderate elasticity. The elastic arms 72b and 72c provide a watertight seal between the upper surface 42a of the inclined portion 42 and the interior of the cover body 70, preventing water from entering the space 81 between the base material 34 (see Figure 2) and the convex hollow portion 18c. However, even if water does enter this space, it can be drained through the drainage notch 58 (see FIG. 4) and the drainage hole 56.

[0039] The small opening 73a of the inclined portion 42 reaches approximately the middle position B of the second holding portion 80 within the space 81, and elastically abuts the lower end of the heat-expandable absorbing elastic material 74, restricting insertion toward the X1 side. In other words, the heat-expandable absorbing elastic material 74 has a simple positioning function when being inserted into the space 81 of the inclined portion 42, making the work easier for the worker.

[0040] As shown in FIG. 2, the water flashing member 10a of the water flashing structure 10 is secured from the outside of the room by placing the mounting pieces 48, 50 on the upper surface 34b of the base material 34, and then the first visible piece 44 abuts against the outdoor-facing visible surface 34a of the base material 34 with screws 64. The water flashing member 10a may be secured by cutting the first visible piece 44 directly below the first mounting piece 48 to form an L-shape, and securing the second visible piece 46 with screws 64. After installing the water flashing member 10a, a backup material 60 is installed between the convex hollow portion 18c and the inclined portion 42, and a sealant 62 is injected. The exterior wall 40 is then constructed.

[0041] As shown in FIG. 1, the top surface of end cover 10b is sealed to vertical portion 40A of exterior wall 40 that runs along vertical frame 20 with sealant 62. This portion is designated by reference numeral 62A in FIG. 1. The gap between vertical portion 40A and vertical frame 20 is also sealed with sealant 62. This portion is designated by reference numeral 62B in FIG. 1. The lower end of sealant 62B seals the interior end of end cover 10b. Backup material 60 may be provided for sealants 62A and 62B as needed. In this way, end cover 10b is fixed to exterior walls 40 and 40A via sealant 62.

[0042] The water-repellent member 10a may expand or contract in the X direction due to heat. As a result, the edge 73a of the inclined portion 42 is displaced toward the X1 or X2 side, as indicated by arrow A in FIG. 5 . When the water-repellent member 10a expands and the edge 73a is displaced toward the X1 side, the heat-expandable elastic material 74 is compressed. However, the displacement is absorbed by the heat-expandable elastic material 74, and the force applied to the cover body 70 is limited. Therefore, almost no external force is applied to the sealants 62A and 62B provided between the edge cover 10b and the outer wall 40. On the other hand, when the water-repellent member 10a contracts and the edge 73a is displaced toward the X2 side, no force is applied to the heat-expandable elastic material 74 and the cover body 70, and naturally, there is no effect on the sealants 62A and 62B. The edge 73a may be displaced toward the X2 side, thereby separating from the heat-expandable elastic material 74. In this way, the edge cover 10b according to this embodiment can absorb the thermal expansion and contraction of the draining member 10a.

[0043] The edge cover 10b covers at least the edge 73a of the inclined portion 42 of the edge 73 of the drainer member 10a, and the cap 10c covers the edge 73b of the drainer piece 52. In this way, the function of covering the edge 73 can be shared between the edge cover 10b and the cap 10c, and the height of the edge cover 10b can be reduced. However, depending on the conditions, the edge cover 10b may cover the edge 73b. The edge 73c of the first visible piece 44 (see FIG. 7) is covered by the outer wall 40A (see FIG. 1), but depending on the conditions, it may be covered by the edge cover 10b.

[0044] The edge cover 10b and cap 10c can also be applied to the edges of other shaped members than the water-repellent member 10a. When applying the edge cover 10b to other shaped members, it is preferable to orient the seal material 72 so that it elastically abuts against the painted surface, decorative surface, and visible surface (first surface), thereby preventing scratches due to sliding contact. When the shaped member to be applied is the upper edge of the vertical frame 20, the elastic material corresponding to the seal material 72 may not be airtight.

[0045] The present invention is not limited to the above-described embodiment, and can of course be freely modified within the scope of the gist of the present invention.

[0046] This embodiment is an end cover that is provided on the end of a shaped member in a building fixture, and comprises a cover body that includes an end wall that covers the end of a plate-shaped portion of the shaped member, a first retaining portion that protrudes from the end wall in the extension direction of the shaped member and faces a first surface of the plate-shaped portion, a second retaining portion that protrudes from the end wall in the extension direction of the shaped member and abuts against a second surface side opposite the first surface to hold the plate-shaped portion, a first elastic material that is provided on the first retaining portion and elastically abuts against the first surface to hold it, and a second elastic material that is provided between the end and the end wall, and the shaped member is a water-draining member that receives water flowing in from the bottom frame of the building fixture and directs it to the outside of the room, and the first surface is the upper surface.

[0047] Since such a fore-edge cover is not fixed to the frame, it can absorb the thermal expansion and contraction of the frame. The first elastic member abuts on the upper surface of the drainage member and has a waterproofing effect.

[0048] The cover body is made of an extruded profile, and if a cap is provided to close the exterior end, the visible surface of the end of the drain member can be closed.

[0049] The first holding portion forms a hollow portion, and the hollow portion has a pocket on the side opposite the first surface for fixing the first elastic material, and when the cover fitting portion of the cap fits into the hollow portion, attachment is easy.

[0050] The first elastic material is an airtight material, and when provided over the entire length of the cover body in the extending direction, it reliably shuts off water.

[0051] The second elastic member may be cylindrical when uncompressed, be provided along the extension direction of the cover body, and be in contact with the end wall, the first retaining portion, the second retaining portion, and the drainage member in an elastically compressed state. A cylindrical second elastic member is versatile and inexpensive, and has a shape that makes it easy to contact the end wall, the first retaining portion, the second retaining portion, and the drainage member, and is easy to insert into the cover body. Furthermore, the cylindrical shape does not limit the installation direction, so installation direction errors are unlikely to occur. [Explanation of symbols]
