Description

[Technical field]

[0001] The present invention relates to gutters, which are devices for collecting rainwater that falls on the roof of a building such as a house and discharging it to the ground or sewer, and to eaves gutters that are attached to the eaves. [Background technology]

[0002] Generally, buildings such as houses are provided with gutters, which are devices for collecting rainwater that falls on the roof and draining it to the ground or sewer. The gutters are mainly composed of an eaves gutter that runs horizontally along the eaves and serves to collect rainwater that runs down from the roof, and a downspout that runs vertically downward from the eaves gutter and serves to drain the rainwater collected by the eaves gutter to the ground or sewer.

[0003] Gutters are installed on the exterior of a building and are an element that constitutes the exterior appearance of the building. The exterior appearance of a building affects the impression of the building itself and the surrounding landscape, and is an important element that can ultimately affect the value of the building. For example, when a house is sold or bought, it is quite conceivable that the exterior appearance of the house can be a deciding factor for a consumer as to whether or not to purchase the house.

[0004] Of the gutters, it is often possible to hide or make the vertical gutters less noticeable from the outside by arranging them in an inconspicuous place such as the corner of the outer wall edge, or on the back or side of the building where they cannot be seen from the front of the building. However, it is often difficult to hide the eaves gutters from the outside because they are installed to extend horizontally along the eaves of the roof. For example, in the case of a building with a hipped roof that has a roof surface that slopes in four directions, the eaves are usually formed on all four sides of the building, and the eaves gutters are also installed to surround the building, so the eaves gutters have to be installed in a place exposed to the outside. Therefore, it is important for the eaves gutters not only to drain rainwater that falls from the roof, but also to have an aesthetic appearance, and the eaves gutters can improve the impression of the eaves and the overall appearance of the building.

[0005] Generally, the eaves gutter is formed as a groove with an opening at the top, and rainwater that flows down from the roof is received in the groove from the opening at the top, and the rainwater that has been received in the groove is sent through the flow path in the groove to a place where a downspout is connected. In a conventional eaves gutter, the height of the outdoor side wall and the indoor side wall of the groove are formed to be approximately equal, and when the eaves are installed at the eaves, there is a risk that the eaves of the roof will be visible when viewed from below, which will spoil the appearance. In order to solve this problem, it has been proposed to provide a standing piece that rises diagonally upward from the upper end of the outdoor side wall of the eaves gutter groove toward the roof side (see, for example, Patent Documents 1 and 2). By providing such a standing piece, the standing piece can hide the eaves of the roof and can be integrated with the roof, improving the appearance, and it is also described that the appearance can be improved by making the slope of the standing piece approximately match the slope of the roof. In addition, an eaves gutter has also been proposed in which the standing piece is formed separately from the outdoor side wall and a rainwater inflow gap is provided between them (see, for example, Patent Document 3). [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Publication No. 03-018321 [Patent Document 2] Publication No. 04-076844 [Patent Document 3] Japanese Patent Application Publication No. 08-326240 Summary of the Invention [Problem to be solved by the invention]

[0007] In the eaves gutter described in Patent Documents 1-3 above, the outdoor side wall of the eaves gutter groove is formed as a flat surface rising almost vertically or as a curved surface convex toward the outdoor side, and a standing piece is provided extending obliquely upward from the upper end of the outdoor side wall toward the roof at a gradient almost equal to that of the roof, so that the standing piece hides the eaves edge and gives a sense of unity with the roof, but as described in Patent Document 3, the outdoor side wall is shaped to bulge toward the outdoor side, giving a sense of volume to the appearance of the eaves edge. However, in recent years, the exterior designs of buildings have become more diverse, and an appearance that gives a sharp and neat impression is often preferred even at the eaves edge, and the eaves gutter that gives a sense of volume as described in Patent Documents 1-3 could not meet such demands.

[0008] The present invention has been made in consideration of the above circumstances, and has an object to provide an eaves gutter that can give a sharp impression to the eaves of a building and improve its appearance. [Means for solving the problem]

[0009] In order to solve the above problems, the eaves gutter of the present invention is an eaves gutter that is attached along the eaves edge of a building to receive and drain rainwater that flows down from the tip of the roof at the eaves edge, and includes a gutter body formed into a groove shape with an upper portion opening longitudinally along the eaves edge by a bottom wall and a front wall and a rear wall that stand on either side of the bottom wall, and a rising portion that is provided above the gutter body along the longitudinal direction of the gutter body, and the gutter body includes a front wall that is disposed on the outdoor side, and an outer surface of the front wall that is disposed on the outdoor side is an inclined surface that slopes diagonally downward from the outdoor side toward the indoor side, and the rising portion includes a rising wall whose outer surface is an inclined surface that slopes diagonally upward toward the indoor side from a position that is horizontally recessed from the outdoor end of the front wall, and a protruding portion that is provided to protrude from the upper end of the rising wall to the outdoor side along the longitudinal direction of the rising wall. the rising wall is provided with an extension wall extending from a lower end edge of the rising wall, the protruding portion has an upper surface of the protruding portion inclined obliquely downward from the protruding end of the protruding portion toward the indoor side, the horizontal positions of the indoor side end edge of the upper surface of the protruding portion and the indoor side end edge of the extending wall are each the horizontal indoor side end of the rising portion and are each located on the outdoor side of the bottom wall, and the horizontal position of the protruding end of the protruding portion is located approximately in the horizontal center of the outer surface of the rising wall. It is characterized by:

[0011] Preferably, the eaves gutter of the present invention is characterized in that the gutter body and the rising portion are constructed as separate parts, and when attached to the eaves, a slit is formed between the gutter body and the rising portion for directing rainwater into the groove of the gutter body.

[0012] Preferably, the eaves gutter according to the present invention is characterized in that the inclination angle of the outer surface of the rising wall with respect to the horizontal plane is larger than the inclination angle of the roof with respect to the horizontal plane. Effect of the Invention

[0013] The eaves gutter of the present invention is an eaves gutter that is attached along the eaves edge of a building to receive and drain rainwater that flows down from the tip of the roof at the eaves edge, and comprises a gutter body formed in a groove shape with an upper portion opening longitudinally along the eaves edge by a bottom wall and a front wall and a rear wall that stand on either side of the bottom wall, and a rising portion that is provided above the gutter body along the longitudinal direction of the gutter body, and the outer surface of the front wall that is located on the outdoor side is an inclined surface that slopes diagonally downward from the outdoor side toward the indoor side, and the rising portion is located at a position where the outer surface is recessed horizontally indoors from the outdoor side end of the front wall. The gutter body attached to the eaves has a front wall disposed on the outdoor side that is an inclined surface that slopes diagonally downward toward the indoor side, and a protruding portion that protrudes from the upper end of the upright wall along the longitudinal direction of the upright wall, and the gutter body attached to the eaves has an outer surface of the front wall disposed on the outdoor side that slopes diagonally downward toward the indoor side and connects to the underside of the bottom wall, so that the outer surface of the front wall is flat and the boundary with the underside of the bottom wall is linear, giving a sharp impression to the appearance of the eaves, and a clean impression with the front wall's bulging to the outdoor side reduced, thereby improving the appearance of the eaves. Also, a rising portion is provided above the gutter body, which can hide the parts of the eaves that cannot be hidden by the gutter body, and the outer surface of the rising wall of the rising portion is an inclined surface that slopes diagonally upward toward the indoor side from a position horizontally recessed from the outdoor end of the front wall of the gutter body, reducing the bulging of the rising wall to the outdoor side, thereby improving the appearance of the eaves. In addition, the rising portion has a protrusion that protrudes from the upper end of the rising wall toward the outdoors, and the protrusion serves as an accent in the appearance, while the shadow formed by the protrusion further improves the appearance of the eaves.

[0014] Preferably, the eaves gutter of the present invention is characterized in that the protrusion has an upper surface that slopes diagonally downward from the protruding end of the protrusion toward the indoor side, and when it rains, the rising portion located above the gutter main body will get wet with rain, but the protrusion is located at the upper end of the rising portion, and by providing the protrusion, the degree to which the area below the protrusion of the rising portion will get wet from rain is reduced compared to when the protrusion is not provided, and since the upper surface of the protrusion is sloped toward the indoor side, rain that falls on the protrusion flows toward the indoor side along the slope of the upper surface of the protrusion and falls into the groove from the opening above the gutter main body, thereby reducing the amount of rainwater that wets the outdoor side of the rising portion.

[0015] Preferably, the eaves gutter of the present invention is characterized in that the gutter body and the rising portion are constructed as separate members, and when attached to the eaves, a slit is formed between the gutter body and the rising portion to introduce rainwater into the groove of the gutter body, so that even if it rains and the outer surface of the rising wall of the rising portion gets wet, the rainwater dripping from the rising wall can flow through the slit between the gutter body and the rising portion into the groove of the gutter body, reducing the risk that the rainwater from the rising portion will flow to the outside side of the gutter body and wet the outer surface of the gutter body or the eaves. Also, since the outer surface of the gutter body is less likely to get wet, it is possible to prevent the design from being impaired by dirt caused by raindrops.

[0016] Preferably, the eaves gutter of the present invention is characterized in that the inclination angle of the outer surface of the rising wall relative to the horizontal plane is greater than the inclination angle of the outer surface of the rising wall relative to the horizontal plane of the roof, so that when the outer surface of the rising wall has the same width, the rising wall can hide a wider area of ​​the eaves edge compared to when the outer surface of the rising wall is set to match the slope of the roof.

[Diagram 3] 1 is a cross-sectional perspective view showing the state of an eaves edge after an eaves gutter according to one embodiment of the present invention has been installed. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0018] An embodiment of the eaves gutter according to the present invention will be described below with reference to the drawings. However, the following is merely an example of one embodiment of the present invention, and the scope of the present invention is not limited to the following embodiment, and can be modified as appropriate without departing from the concept of the present invention.

[0019] As shown in Figs. 1 to 3, an eaves gutter 1 according to an embodiment of the present invention is provided along the eaves edge 8 of the roof of a building such as a house. Generally, the roof of a house is a sloped roof with a slope on the roof surface to improve drainage and prevent leaks. Rainwater that falls on the roof flows downward along the slope of the roof surface and falls from the tip of the roof to the ground. If rainwater falls directly from the roof to the ground, it can cause various problems such as noise caused by the impact of the water landing, weakening of the ground due to holes or puddles created in the ground by the impact of the water landing, and dirt on exterior walls and the like due to mud splashes. Therefore, rainwater that falls on the roof needs to be properly drained. The eaves gutter 1 is provided at the eaves edge 8, which is the tip of such a roof, to receive rainwater flowing down from the tip of the roof and prevent the rainwater from falling directly from the roof to the ground. Rainwater received by the eaves gutter 1 at the eaves edge 8 is collected by the eaves gutter 1 to a specified location, and then drained to a drain or sewer, etc., installed on the ground via a vertically extending downpipe connected to the eaves gutter 1 at that location.

[0020] In this embodiment, the eaves edge 8 where the eaves gutter 1 is provided has a structure as shown in FIG. 1. The roof of this embodiment is a sloping roof with a sloping roof surface, and a plurality of rafters 81 are provided from the ridge part at an angle downwards in a substantially parallel manner, and a roof board 82 and a waterproofing material 83 are laid on these rafters 81 to form a roof foundation, and a roofing material 84 is attached to the roof foundation via a tile batten or the like. As shown in FIG. 2, the lower part of the roof is formed by projecting outward from the exterior wall 9 to the outdoor side to form an eaves, and the tip part of the eaves on the outdoor side, that is, the tip part of the lower end of the roof, is the eaves edge 8. In this embodiment, an eaves soffit material 86 is provided below the rafters 81 via a joist 85, and the lower surface of the eaves soffit material 86 forms an eaves ceiling that extends horizontally from the exterior wall 9 to the eaves edge 8.

[0021] At the eaves end 8, a fascia board 87 is provided extending laterally along the eaves end 8. The fascia board 87 is a strip-shaped plate member that hides the ends of the rafters 81 and the joists 85 from the outside view, and is used as a base for attaching the eaves gutter 1. In this embodiment, as shown in Figs. 1 and 2, the fascia board 87 is provided so that its outer surface facing the outdoors is a substantially vertical plane. In the following, unless otherwise specified, the horizontal direction refers to the horizontal direction in a cross section perpendicular to the longitudinal direction of the eaves end 8, that is, the left-right direction in Fig. 1. In addition, the outdoor side refers to the outdoor side in the horizontal direction, and the indoor side refers to the indoor side in the horizontal direction.

[0022] In the eaves 8 of this embodiment, the ends of the rafters 81 are formed to be substantially vertical, the fascia 87 is attached to the tips of the rafters 81, the sheathing boards 82 laid on the top of the rafters 81 cover up to the top of the fascia 87, a wide lattice 88 is provided on the top surface of the outdoor end of the sheathing boards 82, the waterproofing material 83 is laid so as to cover up to the wide lattice 88, and the roofing material 84 covers them all. Therefore, the outdoor outer surface of the fascia 87 is located below the roofing material 84, and is positioned further inside the building than the tips of the roofing material 84.

[0023] The eaves gutter 1 is attached to such an eaves edge 8 and comprises a gutter body 10 having the main function of the eaves gutter 1 to receive and collect rainwater from the roof, and a rising portion 20 having the main function of screening the eaves edge 8 from outside views. In the eaves gutter 1 according to this embodiment, the gutter body 10 and the rising portion 20 are configured as separate members.

[0024] As shown in Fig. 1, the gutter body 10 according to this embodiment includes a substantially rectangular bottom wall 11, a rear wall 12 rising substantially vertically upward from one of the long sides of the bottom wall 11, and a front wall 13 rising obliquely upward in the opposite direction to the rear wall 12 side from the other long side of the bottom wall 11, and is surrounded on three sides by the bottom wall 11 and the rear wall 12 and front wall 13 rising from a pair of long sides of the bottom wall 11, respectively, and is formed into a concave groove shape with a longitudinal opening at the top. The gutter body 10 is attached along the fascia 87 of the eaves 8 in an orientation in which the bottom wall 11 is placed downward, the rear wall 12 faces the fascia 87, and the front wall 13 is disposed on the outdoor side. When the gutter body 10 is attached to the eaves 8, the horizontal position of the tip of the roof material 84 is located between the horizontal position of the upper end of the rear wall 12 and the horizontal position of the upper end of the front wall 13. Therefore, rainwater running down from the tip of the roof material 84 is received by the gutter body 10 through the upper opening into the inside of the recessed groove.

[0025] As shown in FIG. 1, a drip-water board 89 may be provided at the eaves 8. The drip-water board 89 is a member for preventing rainwater flowing down from the tip of the roof material 84 from flowing indoors and wetting the eaves ceiling and exterior wall 9. In this embodiment, the drip-water board 89 is provided so as to extend diagonally downward from the wide lattice 88 along the eaves 8 toward the outdoor side. The horizontal position of the lower end of the drip-water board 89 is located between the horizontal positions of the upper ends of the rear wall 12 and front wall 13 of the gutter body 10, and rainwater flowing down from the drip-water board 89 also falls into the groove from the opening at the top of the gutter body 10.

[0026] The rainwater received in the groove of the gutter body 10 flows through the groove of the gutter body 10 as a flow path to a predetermined location where a vertical gutter is connected to the gutter body 10. In order for the rainwater to flow through the groove of the gutter body 10 as a flow path, a water gradient is provided in the groove of the gutter body 10 along the eaves 8 when the gutter body 10 is attached to the eaves 8. In this embodiment, the gutter body 10 is formed by bending and forming a single thin plate-like member, but when the cross-sectional shape of the groove of the gutter body 10 is constant in the longitudinal direction as in this embodiment, the gutter body 10 itself may be inclined and attached along the eaves 8 to provide a water gradient. In this case, it is preferable in terms of appearance that the gutter body 10 is attached so that the lower surface of the bottom wall 11 is approximately horizontal along the eaves 8 as much as possible after securing a water gradient that can exert the necessary drainage capacity.

[0027] In this embodiment, when the gutter body 10 is attached to the eaves 8, the height position of the upper end of the rear wall 12 and the height position of the upper end of the front wall 13 are approximately equal, and the upper end edge of the outer surface of the front wall 13 is located horizontally furthest from the outside and vertically furthest in the gutter body 10. The gutter body 10 may be formed so that either the height position of the upper end of the rear wall 12 or the height position of the upper end of the front wall 13 is higher. In that case, the gutter body 10 can only store water up to the lower height position of the upper end of the rear wall 12 or the upper end of the front wall 13. Therefore, after forming the rear wall 12 and the front wall 13 to a height that ensures the necessary water receiving capacity in the groove, one of them is further raised, and the raised part is a wasteful part from the viewpoint of the function of the gutter body 10 as a groove. Therefore, it is better to make the height positions of the upper end of the rear wall 12 and the upper end of the front wall 13 approximately equal to reduce the material cost of the gutter body 10.

[0028] Since the eaves 8 is usually located at a position higher than the eye height of an average person, the line of sight from outside to the gutter body 10 attached to the eaves 8 is as if looking up from below or diagonally below the outdoor side. Therefore, the gutter body 10 attached to the eaves 8 has two planes, the lower surface of the bottom wall 11 which is a substantially horizontal plane, the outer surface of the front wall 13 which is a sloping surface extending diagonally upward from the bottom wall 11 to the outdoor side, and a straight line formed at the boundary between the lower surface of the bottom wall 11 and the outer surface of the front wall 13. In this way, the appearance of the gutter body 10 is composed of planes and straight lines, which can give the eaves 8 a sharp impression, and since the front wall 13 is a sloping surface that slopes diagonally downward from the outdoor side toward the indoor side, the bulging feeling of the front wall 13 toward the outdoor side is reduced, and the eaves 8 can be given a neat impression. Here, the angle α between the underside of bottom wall 11 and the outer surface of front wall 13 will be greater than 90 degrees and less than 180 degrees; however, if the angle α is brought closer to 90 degrees, the outer surface of front wall 13 will approach nearly vertical, giving the front wall 13 a greater sense of bulging out toward the outdoors, and if the angle α is brought closer to 180 degrees, the depth of the groove in the gutter body 10 will become smaller and it will no longer be possible to secure the necessary water-receiving volume of the groove. Therefore, although not limited to this, the angle α is preferably in the range of 120 degrees to 150 degrees, near 135 degrees, which is the midpoint between 90 degrees and 180 degrees, and more preferably in the range of 130 degrees to 140 degrees.

[0029] In this embodiment, the eaves including the eaves end 8 are formed with a horizontal eaves ceiling by the eaves ceiling material 86, and the gutter body 10 is preferably provided so that the height position of the lower surface of the bottom wall 11 is approximately equal to the height position of the lower surface of the eaves ceiling material 86. Alternatively, if the lower surface of the fascia board 87 is provided so that it protrudes below the lower surface of the eaves ceiling material 86, the height position of the lower surface of the bottom wall 11 may be aligned with the height position of the lower surface of the fascia board 87. The eaves end 8 before the gutter body 10 is attached has an appearance with many projections and recesses between the eaves ceiling and the roof, such that the vertical surface of the fascia board 87 rises from the horizontal eaves ceiling of the eaves ceiling material 86, and the tip portion of the roof material 84 protrudes from the fascia board 87 to the outdoors side, sandwiching the sheathing board 82, the wide lattice 88, etc. By attaching the gutter body 10 to such an eaves edge 8, the unevenness of the eaves edge 8 is hidden, and the two flat surfaces of the bottom wall 11 extending from the eaves ceiling to the outdoors in a roughly flush manner, and the front wall 13 extending from the extending end of the bottom wall 11 diagonally upwards to the outdoors, give the appearance of a unified connection from the eaves ceiling to the roof.

[0030] The rising portion 20 is provided above the gutter main body 10 so as to extend along the longitudinal direction of the gutter main body 10, and includes a rising wall 21 whose outer surface is an inclined surface rising diagonally upward, and a protruding portion 22 that protrudes from the upper end of the rising wall 21 along the longitudinal direction of the rising wall 21. In this embodiment, as shown in Figures 2 and 3, the rising portion 20 is configured as a separate member from the gutter main body 10, and is attached to the eaves 8 together with the gutter main body 10.

[0031] When the eaves gutter 1 is attached to the eaves edge 8, the rising portion 20 is disposed above the gutter body 10, which is a groove-shaped groove with an open top, and rainwater that flows down from the tip of the roof material 84 into the groove from the opening at the top is received. Therefore, the rising portion 20 is disposed near the outdoor end of the gutter body 10 so as not to block the opening at the top of the gutter body 10 as much as possible. However, if the rising portion 20 is disposed on the outdoor side of the gutter body 10, the rising portion 20 will give the eaves edge 8 a sense of bulging toward the outdoor side and there is a risk of dirt being generated due to raindrops. Therefore, the outdoor end of the rising portion 20 is disposed at a position recessed toward the indoor side from the outdoor end of the gutter body 10. The outdoor end of the gutter body 10 is the upper edge of the outer surface of the front wall 13. The outdoor end of the rising portion 20 is the lower end edge of the outer surface of the rising wall 21, and the outer surface of the rising wall 21 is an inclined surface that rises obliquely upward toward the indoor side from the lower end edge that is located at a position recessed indoors from the outdoor end of the gutter body 10 near the outdoor end of the gutter body 10. The protruding portion 22 is provided so as to protrude toward the outdoor side from the upper end edge of the outer surface of the rising wall 21, and extends along the longitudinal direction of the rising wall 21. The protruding end of the protruding portion 22 is the upper end of the rising portion 20. The horizontal position of the protruding end of the protruding portion 22 does not exceed the horizontal position of the lower end edge of the outer surface of the rising wall 21. In this embodiment, the protrusion 22 includes a protrusion lower surface 221 extending obliquely upward on the outdoor side from the upper end edge of the outer surface of the rising wall 21, and a protrusion upper surface 222 extending obliquely downward on the indoor side from the extending end edge of the protrusion lower surface 221, and the protrusion lower surface 221 and the protrusion upper surface 222 form a substantially mountain-shaped cross section.

[0032] By providing an eaves gutter 1 having such a rising portion 20 at the eaves end 8, the rising portion 20 can hide from external views parts of the eaves end 8 that are undesirable to be seen from the outside, such as the upper part of the fascia board 87, the ends of the sheathing board 82, waterproofing material 83, wide lattice 88, etc. between the fascia board 87 and the tip of the roof material 84, and the drip board 89, even in cases where such parts cannot be completely hidden by simply installing the gutter main body 10.

[0033] In addition, the lower end edge of the outer surface of the rising wall 21, which is the horizontal outdoor end of the rising portion 20, is located at a position deeper inside than the horizontal outdoor end of the gutter main body 10, and the outer surface of the rising wall 21 is an inclined surface that rises diagonally upward from the lower end edge on the outdoor side toward the indoor side.Therefore, the rising portion 20 enhances the sense of unity connecting the gutter main body 10 to the roof, while suppressing the sense of bulging toward the outdoors, giving a clean impression and improving the appearance of the eaves 8.

[0034] Furthermore, since the rising portion 20 includes a protrusion 22 that protrudes from the upper end of the rising wall 21 toward the outdoors, the protrusion 22 functions as a direct accent in terms of appearance, and when sunlight is incident on the rising portion 20, the protrusion 22 located at the upper end of the rising portion 20 blocks the sunlight and casts a shadow below it. Since the protrusion 22 extends linearly in the longitudinal direction of the rising portion 20, the shadow formed by the sunlight incident on the protrusion 22 also becomes a band-shaped shadow extending in the longitudinal direction of the rising portion 20. The width and color density of the shadow change depending on the angle and intensity of sunlight, and therefore change depending on the weather, time, season, etc. When the rising portion 20 is viewed from the outside, the rising portion 20 may be entirely covered in shadow or may not be shaded, but when the bottom end of the shadow is located on the outer surface of the rising wall 21, that is, when the shadow of the protruding end of the protruding portion 22 caused by sunlight is projected onto the outer surface of the rising wall 21, a contrast of light and dark is formed in the appearance of the rising portion 20, with a band-like dark area extending from the bottom end of the shadow to the top and a band-like light area extending from the bottom end of the shadow to the bottom. In this way, the protruding portion 22 forms a contrast of light and dark due to the shadow in the appearance of the rising portion 20, and the eaves 8 on which the rising portion 20 is installed can be given a varied and timeless appearance.

[0035] In this embodiment, at the eaves 8, the horizontal position of the protruding end of the protruding portion 22 does not exceed the horizontal position of the lower end edge of the outer surface of the rising wall 21 on the outdoor side. As the horizontal position of the protruding end of the protruding portion 22 approaches the horizontal position of the lower end edge of the outer surface of the rising wall 21, the protruding length of the protruding portion 22 increases, the protruding portion 22 becomes more conspicuous in appearance, and the size of the shadow formed by the protruding portion 22 also increases. Conversely, as the horizontal position of the protruding end of the protruding portion 22 approaches the horizontal position of the upper end edge of the outer surface of the rising wall 21, the protruding length of the protruding portion 22 decreases, the protruding portion 22 becomes less conspicuous in appearance, and the size of the shadow formed by the protruding portion 22 also decreases. The protruding length of the protruding portion 22 may be appropriately designed taking these factors into consideration, and although not limited thereto, it is preferable that the horizontal position of the protruding end of the protruding portion 22 is included in the middle region obtained by horizontally dividing the outer surface of the standing wall 21 into three equal parts, and more preferably that it is located approximately in the horizontal center of the outer surface of the standing wall 21. This allows the protruding portion 22 in the standing portion 20 to have a moderate protruding feeling toward the outdoors, and the lower end of the shadow formed by the protruding portion 22 is likely to be located on the outer surface of the standing wall 21, making it easy to form a light and dark contrast in the standing portion 20.

[0036] The eaves gutter 1 according to this embodiment is attached to the eaves edge 8 using an eaves gutter mounting fixture 5. As shown in Fig. 2 and Fig. 3, multiple eaves gutter mounting fixtures 5 are attached to the eaves edge 8 at predetermined intervals in the longitudinal direction of the fascia 85 of the eaves edge 8. By attaching the eaves gutter 1 to these eaves gutter mounting fixtures 5, the eaves gutter 1 is attached to the eaves edge 8 via the eaves gutter mounting fixtures 5.

[0037] The eaves gutter mounting fixture 5 according to this embodiment has an eaves end fixing portion 51 , a rising portion mounting portion 52 , and a gutter main body mounting portion 53 .

[0038] The eaves edge fixing part 51 has a flat portion 511 which abuts the outdoor outer surface of the fascia 87, an inclined portion 512 which curves at an acute angle from the upper end of the flat portion 511 and extends diagonally downward to the outdoor side, and a horizontal portion 513 which extends horizontally to the outdoor side from the extending end of the inclined portion 512. The eaves gutter mounting fixture 5 is fixed to the eaves edge 8 by abutting the flat portion 511 of the eaves edge fixing part 51 against the fascia 87 of the eaves edge 8 and fixing it with screws or the like.

[0039] The rising portion mounting portion 52 has a gutter main body holding portion 521, an inclined portion 522 that curves at an acute angle from the upper end of the gutter main body holding portion 521 and extends diagonally downward toward the outdoor side, a horizontal portion 523 that extends horizontally from the extended end of the inclined portion 522 toward the outdoor side, a rising portion 524 that rises upward from the extended end of the horizontal portion 523, a locking portion 525 that extends from the extended end of the rising portion 524 to the outdoor side, an inclined portion 526 that curves at an acute angle from the extended end of the locking portion 525 and extends diagonally upward toward the indoor side, and a locking piece portion 527 that extends diagonally upward on the outdoor side from the extended end of the inclined portion 526. The rising portion mounting portion 52 is mounted to the eaves fixing portion 51 such that the upper surfaces of the inclined portion 522 and the horizontal portion 523 of the rising portion mounting portion 52 abut against the lower surfaces of the inclined portion 512 and the horizontal portion 513 of the eaves fixing portion 51, respectively. The curvature of the curved portion at the upper end of the inclined portion 522 of the rising portion mounting portion 52 is greater than the curvature of the curved portion at the upper end of the inclined portion 512 of the eaves fixing portion 51, and the gutter main body holding portion 521 has a generally mountain-shaped cross section that extends diagonally downward on the outdoor side from the curved portion of the inclined portion 522 and then extends toward the flat portion 511 so as to rise above the outdoor side relative to the flat portion 511 of the eaves fixing portion 51.

[0040] The gutter body mounting part 53 has a horizontal part 531 extending horizontally toward the outdoor side, and a locking part 532 extending obliquely upward toward the outdoor side from the extending end of the horizontal part 531. The gutter body mounting part 53 is mounted to the eaves fixing part 51 via the rising part mounting part 52 and the rising part mounting part 52 so that the upper surface of the horizontal part 531 of the gutter body mounting part 53 abuts against the lower surface of the horizontal part 523 of the rising part mounting part 52. At this time, the indoor side of the horizontal part 523 of the rising part mounting part 52 is configured so that the inclined part 522 rises from its indoor side end toward the indoor side obliquely upward, but the horizontal part 531 of the gutter body mounting part 53 is provided so as to protrude indoors beyond the indoor side end of the horizontal part 523 of the rising part mounting part 52, and the indoor side end of the horizontal part 531 is positioned below the inclined part 522 of the rising part mounting part 52.

[0041] The eaves fixing part 51, the rising part mounting part 52 and the gutter body mounting part 53 can each be formed by bending and forming a strip-shaped member. The strip-shaped members for forming the eaves fixing part 51, the rising part mounting part 52 and the gutter body mounting part 53 are of approximately equal width, but it is preferable to use a strip-shaped member for forming the eaves fixing part 51 such that the part that becomes the flat part 511 is flat and protrudes in the width direction more than the other parts. As a result, when the rising part mounting part 52 is attached to the eaves fixing part 51, the flat part 511 of the eaves fixing part 51 protrudes in the width direction more than the gutter body pressing part 521 of the rising part mounting part 52, so that the protruding part of the flat part 511 can be used to fix the eaves fixing part 51 to the fascia board 87 with a screw or the like, and therefore the eaves gutter mounting fixture 5 can be easily attached to the fascia board 87.

[0042] The gutter body 10 of this embodiment is provided with a water-guide wall 15 extending diagonally downward from the upper end edge of the front wall 13 toward the rear wall 12 on the front wall 13, and a locking piece 16 extending downward from the extending end of the water-guide wall 15, so that it can be attached to such an eaves gutter mounting fixture 5, and a locking portion 17 extending diagonally downward from the upper end edge of the rear wall 12 toward the front wall 13 on the rear wall 12. In this way, the water guide wall 15 extends from the upper end of the front wall 13, and the locking portion 17 extends from the upper end of the rear wall 12, toward the inside of the groove of the gutter body 10, so that the width of the opening at the top of the groove of the gutter body 10 is narrowed by the horizontal extension length of the water guide wall 15 and the locking portion 17, but because the water guide wall 15 and the locking portion 17 are each provided so as to slope diagonally downward toward the inside of the groove, rainwater that falls on the water guide wall 15 or the locking portion 17 falls into the groove along the respective slopes, so that the opening of the groove can essentially be said to extend from the upper end of the front wall 13 to the upper end of the rear wall 12. Moreover, because the water guide wall 15 and the locking portion 17 are each provided so as to extend diagonally downward toward the inside of the groove of the gutter body 10, they do not affect the appearance of the gutter body 10.

[0043] The gutter body 10 of this embodiment has a shape in which the locking piece 16, the water guide wall 15, the front wall 13, the bottom wall 11, the rear wall 12, and the locking portion 17 are continuously connected, and is formed by bending a single thin plate-like member. As such a thin plate-like member, a resin-coated metal plate in which a metal plate that is easy to bend and has a strength to withstand the weight of water received inside as the gutter body 10 is coated with resin to enhance corrosion resistance, for example, a PVC steel plate in which a polyvinyl chloride resin coating is applied to the surface of a steel plate, can be suitably used. In this way, when the gutter body 10 is bent and formed from a single thin plate-like member, the only processing step is the bending step, and the number of parts is small, so that the manufacturing and management costs can be reduced, and the quality can be easily maintained constant compared to when welding or the like is performed.

[0044] The gutter body 10 is attached to the eaves gutter attachment 5 attached to the fascia board 87 by inserting the gutter body attachment part 53 into the groove of the gutter body 10 from the upper opening of the groove, and hooking and engaging the lower end part of the engagement piece 16 on the front wall 13 side to the upper surface of the engagement part 532 of the gutter body attachment part 53 and the lower end part of the engagement part 17 on the rear wall 12 side to the upper surface of the indoor side end part of the horizontal part 531 of the gutter body attachment part 53. At this time, the multiple eaves gutter attachments 5 are attached at intervals from each other along the longitudinal direction of the fascia board 87 at gradually changing height positions so that the gutter body 10 has a predetermined water gradient along the longitudinal direction of the eaves edge 8, and the gutter body 10 is attached to the eaves edge 8 by being attached to these multiple eaves gutter attachments 5, thereby having a predetermined water gradient.

[0045] When the gutter body 10 is attached to the eaves gutter mounting bracket 5, the gutter body mounting portion 53 of the eaves gutter mounting bracket 5 is positioned within the groove of the gutter body 10 at a position slightly below the upper end of the groove. However, since there is a gap between adjacent eaves gutter mounting brackets 5, the eaves gutter mounting bracket 5 does not block the flow of rainwater running down from the roof into the groove of the gutter body 10.

[0046] Furthermore, with the gutter body 10 attached to the eaves gutter mounting fixture 5, the cross-sectionally roughly mountain-shaped portion of the gutter body retaining portion 521 of the eaves gutter mounting fixture 5 abuts against the outer surface of the rear wall 12. As a result, even if wind blows against the gutter body 10 and an external force is applied to the indoor side against the front wall 13 arranged on the outdoor side, the gutter body retaining portion 521 prevents the gutter body 10 from moving to the indoor side, and therefore prevents the locking portion 17 on the rear wall 12 side from coming off the horizontal portion 531 of the gutter body mounting portion 53 and falling off. The rear wall 12 faces the fascia 87, and since the rear wall 12 is not easily subjected to force toward the outdoors by the wind, there is little risk that the gutter body 10 will move toward the outdoors due to external forces.In addition, the locking portion 532 of the gutter body mounting portion 53 extends so as to rise upward diagonally toward the outdoors from the outdoor end of the horizontal portion 531, and the locking piece 16 on the front wall 13 side is locked by being hooked onto the upper surface of this locking portion 532.Therefore, for the locking piece 16 to come off from the locking portion 532 and fall off, the gutter body 10 not only needs to move horizontally toward the outdoors, but also needs to move upward, making it less likely to come off. In this way, the gutter body 10 can be attached to the gutter body mounting fixture 53 of the eaves gutter mounting fixture 5, which has already been attached to the eaves edge 8, by hooking the locking piece 16 and the locking portion 17 from below and engaging them, without the need for any other tools. This makes installation easy, and once the gutter body 10 is attached to the eaves gutter mounting fixture 5, it is less likely to come off due to natural forces, and it can be firmly attached to the eaves edge 8.

[0047] Furthermore, when water from the roof flows into the recessed groove of the gutter body 10 and accumulates, a downward load due to the accumulated water is applied to the gutter body 10, and this load is applied to the gutter body mounting parts 53 of the multiple eaves gutter mounting fixtures 5 to which the gutter body 10 is attached. The eaves gutter mounting fixture 5 is attached to the fascia board 87 by fixing the eaves end fixing part 51 to the fascia board 87, and the downward load applied to the gutter body mounting part 53 by the gutter body 10 is transmitted to the fixing part between the eaves end fixing part 51 and the fascia board 87 via the eaves end fixing part 51 to which the gutter body mounting part 53 is attached, and a moment due to the load of the gutter body 10 is generated around the fixing part. Therefore, the gutter body 10 tries to rotate downward toward the indoor side, but since the rear wall 12 on the indoor side of the gutter body 10 abuts against the gutter body pressing part 521 of the eaves gutter mounting fixture 5, the rotation of the gutter body 10 is prevented by the gutter body pressing part 521. In addition, in this case, since the front wall 13 of the gutter body 10 is arranged so as to incline diagonally downward from the outdoor side to the indoor side, the center of gravity of the gutter body 10 when water is stored in the groove of the gutter body 10 is located on the indoor side rather than the horizontal center of the cross section of the groove of the gutter body 10.As a result, the magnitude of the moment generated at the fixing part between the eaves fixing part 51 and the fascia board 87 is smaller than when the front wall 13 is arranged vertically, thereby reducing the risk of screws or the like fixing the eaves fixing part 51 to the fascia board 87 becoming loose or damaged.

[0048] The rising portion 20 according to this embodiment is attached to the rising portion attachment portion 52 of the eaves gutter attachment tool 5, so as to be attached to the eaves edge 8. In this embodiment, the rising portion 20 is provided with an extension wall 23 extending from the lower end edge of the rising wall 21 and a lower locking piece 24 extending from the extending end of the extension wall 23 on the rising wall 21, and an upper locking piece 25 extending from the extending end of the protruding portion upper surface 222 on the protruding portion 22. The upper locking piece 25 is continuously connected from the protruding portion upper surface 222, the protruding portion lower surface 221, the rising wall 21, the extending wall 23, and the lower locking piece 24, and the rising portion 20 according to this embodiment is formed by bending and molding a single thin plate-like member, similar to the gutter body 10.

[0049] The rising portion mounting portion 52 of the eaves gutter mounting fixture 5 attached to the eaves edge 8 has a horizontal portion 523 that extends horizontally toward the outdoors, from which a rising portion 524 rises upward, a locking portion 525 extends from the upper end of the rising portion 524 diagonally downward toward the outdoors side, and then a curved inclined portion 526 extends diagonally upward toward the indoor side, and a locking piece portion 527 extends from the extending end of the inclined portion 526 diagonally upward toward the outdoors side. The rising portion 20 is attached to the rising portion attachment portion 52 by fitting the locking piece 527 between the valley portion formed by the protruding portion lower surface 221 and the protruding portion upper surface 222 of the protruding portion 22 from the outdoor side of the rising portion attachment portion 52, fitting the curved portion between the inclined portion 526 and the locking piece 526 between the rising wall 21 and the extending wall 23, abutting the rising wall 21 against the inclined portion 526, hooking the lower locking piece 24 provided at the tip of the extending wall 23 to the locking piece 526, and hooking the upper locking piece 25 provided at the tip of the protruding portion upper surface 222 to the corner portion between the locking piece 527 and the inclined portion 526. The rising portion 20 is attached to each of the rising portion attachment portions 52 of the eaves gutter attachment device 5 provided along the longitudinal direction of the fascia 87, thereby being attached to the eaves edge 8.

[0050] In this way, the rising portion 20 can be attached without the need for any other tools by simply pressing it from the outdoor side against the rising portion mounting portion 52 of the eaves gutter mounting fixture 5 that is previously attached to the eaves edge 8 and hooking and locking the lower locking piece 24 and the upper locking piece 25, thus making construction easy. Also, since the gutter main body 10 and the rising portion 20 are constructed as separate members and are each separately and detachably attached to the eaves gutter mounting fixture 5, the gutter main body 10 and the rising portion 20 can be constructed in different colors as necessary, and if either one is damaged, it is sufficient to replace only the damaged one.

[0051] At the eaves 8, the rising portion 20 is disposed above the gutter body 10, and the lower end edge of the rising wall 21, which is the outdoor end of the rising portion 20, is disposed on the indoor side of the upper end edge of the front wall 13, which is the outdoor end of the gutter body 10, in the horizontal direction. In this embodiment, the gutter body 10 is provided with a water guide wall 15 extending obliquely downward toward the indoor side from the upper end edge of the front wall 13, and the rising portion 20 is provided with an extension wall 23 extending indoors from the lower end edge of the rising wall 21, and the gutter body 10 and the rising portion 20 are disposed at the eaves 8 so that the extension wall 23 is inclined obliquely downward toward the indoor side so as to be approximately parallel to the water guide wall 15, and a slit 31 is formed at a predetermined interval between the extension wall 23 and the water guide wall 15.

[0052] In addition, in this embodiment, the rising portion 20 is positioned so that the horizontal position of the indoor side end edge of the extension wall 23 and the horizontal position of the indoor side end edge of the protruding portion upper surface 222 are each the horizontal indoor side end portions of the rising portion 20, and are approximately equal to the horizontal position of the indoor side end edge of the water-conducting wall 15 of the gutter body 10, and the rising portion 20 is positioned above the gutter body 10 within the horizontal width of the water-conducting wall 15 of the gutter body 10 so as not to block the opening of the groove of the gutter body 10.

[0053] Since the rising portion 20 is disposed above the gutter body 10, when it rains, the rain also falls on the rising portion 20. At this time, the protruding portion upper surface 222 at the upper end of the rising portion 20 is inclined diagonally downward toward the indoor side, and the rain that falls on the rising portion 20 falls on the protruding portion upper surface 222, and then flows indoors along the inclination of the protruding portion upper surface 222, and falls into the opening of the recessed groove of the gutter body 10. The horizontal position of the outdoor side end of the protruding portion upper surface 222, which is the protruding end of the protruding portion 22, is located on the indoor side from the horizontal position of the lower end edge of the rising wall 21, and the rain that falls between the outdoor side end of the protruding portion upper surface 222 and the lower end edge of the rising wall 21 adheres to the outdoor side outer surface of the rising wall 21. The rising wall 21 is inclined obliquely downward toward the outdoor side, and rainwater adhering to the outdoor outer surface of the rising wall 21 flows along the inclination of the rising wall 21 to the lower end edge of the rising wall 21, and from there falls onto the water guide wall 15 of the gutter body 10 below, or flows toward the lower surface of the extension wall 23 extending obliquely downward toward the indoor side from the lower end edge of the rising wall 21. Here, the water guide wall 15 and the extension wall 23 are approximately parallel to each other with a gap between them, and they form a slit 31 that extends obliquely downward toward the opening of the groove in the gutter body 10, and rainwater that falls on the water guide wall 15 flows inside the slit 31 along the inclination of the water guide wall 15 and falls into the groove from the opening of the groove in the gutter body 10, and rainwater running along the lower surface of the extension wall 23 also flows inside the slit 31 and falls into the groove from the opening of the groove in the gutter body 10. Furthermore, rainwater that falls between the lower end edge of the rising wall 21 and the upper end edge of the front wall 13 on the outdoor side falls onto the water guide wall 15, then flows along the slope of the water guide wall 15, passes through the slits 31 and falls into the grooves of the gutter body 10. In this way, with the eaves gutter 1 according to this embodiment, even if rainwater falls on the rising portion 20, the rainwater that adheres to the rising portion 20 does not fall directly from the rising portion 20 to the ground, but flows into the grooves of the gutter body 10 and is properly drained by the gutter body 10.

[0054] Here, if the interval between the slits 31 is too small, the amount of rain that falls on the outer surface of the rising wall 21 and on the water guide wall 15 between the lower end edge of the rising wall 21 and the upper end edge of the front wall 13 is likely to be greater than the flow rate of rainwater flowing through the slits 31, and there is a risk that water will accumulate on the outdoor side of the slits 31 and overflow from the upper end of the front wall 13 to the outdoor side. Therefore, the interval between the slits 31 may be appropriately designed according to the expected amount of rainfall, etc., so that rainwater flows smoothly through the slits 31 and does not accumulate on the outdoor side of the slits 31. The interval between the slits 31 can be changed by changing the vertical arrangement of the rising portion 20. The vertical arrangement of the rising portion 20 can be changed by changing the height at which the rising portion 524 of the rising portion mounting portion 52 rises from the horizontal portion 523. However, if the rising portion 20 is positioned too far above the gutter main body 10 and the spacing of the slits 31 becomes too large, a gap will appear between the rising portion 20 and the gutter main body 10 in appearance, and there is a risk that parts that should be hidden by the rising portion 20, such as the wide lattice 88 of the eaves 8 and the drip board 89, will be visible from the outside through the slits 31. Therefore, the spacing of the slits 31 is set so that no gap appears between the rising portion 20 and the gutter main body 10.

[0055] In addition, since the outer surface of the rising wall 21 at the eaves edge 8 is an inclined surface, the inclination angle of the outer surface of the rising wall 21 with respect to the horizontal plane can be greater than 0 degrees and less than 90 degrees; however, if the inclination angle is less than 45 degrees, the width of the rising wall 21 extending horizontally is greater than the height to which the rising wall 21 rises upward. Therefore, if an attempt is made to align the horizontal position of the indoor end of the rising portion 20 with the horizontal position of the indoor end of the water-conducting wall 15 of the gutter main body 10, there is a risk that the height of the rising wall 21 will not be sufficient to fully hide the eaves edge 8, or if an attempt is made to ensure the height of the rising wall 21, the rising portion 20 may block the opening at the top of the gutter main body 10 or the material costs of the rising portion 20 may be high. Conversely, if the inclination angle approaches 90 degrees, the protruding length of the protruding portion 22 will not be sufficient, or the outer surface of the rising wall 21 will become approximately vertical, giving a stronger sense of bulging toward the outdoors. Therefore, the inclination angle of the outer surface of the rising wall 21 with respect to the horizontal plane is preferably within the range of 45 degrees to 80 degrees, and more preferably within the range of 55 degrees to 70 degrees, although this is not limited thereto. Here, the slope of a sloping roof of a house is generally about 3 to 6 sun slope, and a slope of 10 sun or more is considered to be quite steep and is rarely adopted. When the roof slope is 10 sun slope, the slope angle of the roof with respect to the horizontal plane is 45 degrees, so the preferred slope angle of the outer surface of the rising wall 21 with respect to the horizontal plane in this embodiment is greater than the slope angle of the roof with respect to the horizontal plane.

[0056] In addition, the gutter body 10 is designed so that rain falling on the indoor side of the upper end edge of the front wall 13 flows into the groove of the gutter body 10. As for rain falling on the outdoor side of the upper end edge of the front wall 13, the outer surface of the front wall 13 is inclined diagonally downward from the upper end edge toward the indoor side, so that the falling rain hits the outer surface of the front wall 13 when the inclination angle of the rain falling with respect to the vertical direction is greater than the inclination angle of the outer surface of the front wall 13 with respect to the vertical direction. By inclining the outer surface of the front wall 3 of the gutter body 10 in this way, not only is a sharp impression given to the appearance, but it is also difficult for rain to adhere to the outer surface of the front wall 13, so that it is possible to prevent the outer surface of the front wall 13 from becoming dirty due to raindrops and the design from being reduced, and it is also possible to reduce the risk that a large amount of rainwater will adhere to the outer surface of the front wall 13 and flow to the underside of the bottom wall 11, causing the rainwater to fall from the bottom wall 11 to the ground or flow around the eaves ceiling or the outer wall.

[0057] As described above, the eaves gutter 1 according to this embodiment can give a sharp and neat impression to the eaves edge 8 of the building to which the eaves gutter 1 is attached, thereby improving the appearance. [Explanation of symbols]
