Description

[Technical field]

[0001] The present invention relates to a gutter member and a gutter structure. [Background technology]

[0002] Conventionally, a structure in which a stopper is fixed to the open end of a gutter is known, for example as in Patent Document 1. In this structure, the stopper can prevent rainwater inside the gutter from spilling out from the open end. On the other hand, in a structure in which a stopper is fixed to the open end of a gutter, a gap is provided between the ends of two gutter ends facing each other, so it is possible that rainwater will drip from the gap between the two stops. Therefore, for example as in Patent Document 2, it is known to provide a gutter member above the two stops as a gutter member that receives rainwater flowing down between the two stops. [Prior art documents] [Patent documents]

[0003] [Patent Document 1] JP 2004-285601 A [Patent Document 2] JP 2023-051861 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, with conventional gutter components such as that in Patent Document 2, there is a risk that water will splash over the first piece of the gutter component, especially in cases of heavy precipitation, or that water will flow out of the gutter from the end of the first piece if the water flow is strong.

[0005] The present invention has been made in consideration of such problems, and has an object to provide a gutter member and a gutter structure that can prevent water from flowing out of the gutter. [Means for solving the problem]

[0006] In order to solve the above problems, the present invention proposes the following means. <1> A gutter member in one embodiment of the present invention is rectangular in a plan view and comprises a main body having two first sides facing in a first direction and two second sides facing in a second direction, and a first piece extending from at least one of the two first sides to the first side, wherein the width of the first piece in the second direction is greater than the width of the main body in the second direction. This allows the length of the first piece to be longer than the length of the main body in the second direction, which is the direction of water flow. Therefore, the extended portion of the first piece functions as a drainage section, and it is possible to prevent water from flowing out of the gutter from the end of the first piece due to the water flow. This makes it possible to prevent water from flowing out of the gutter and increase the allowable water volume.

[0007] <2> When the gutter member is viewed from the second direction, the angle formed between the main body and the first piece is an acute angle. This makes it possible to suppress the splashing of water that occurs when water hits the first piece. Therefore, even when there is a large amount of water and the water flow is strong, it is possible to suppress the water from going over the first piece. This makes it possible to suppress the outflow of water to the outside of the gutter and to increase the allowable water volume.

[0008] <3> The body portion further includes at least one aperture. This allows the gutter member to be easily fixed in a stable state to the upper end of the catchment by placing the penetrating member in the hole. Therefore, even when there is a large amount of water and the water flow is strong, the gutter member can be prevented from coming off the upper end of the catchment. This prevents water from flowing out of the gutter and increases the allowable water volume.

[0009] <4> It further includes second pieces extending from the two second sides to a second side. This allows the second piece to be hooked onto the stop eaves portion provided on the gutter, preventing the gutter member from shifting out of the stop eaves portion.

[0010] <5> A gutter structure according to one aspect of the present invention includes two gutter sections whose ends face each other, and a stop structure provided between the ends of the gutter sections. The stop structure includes a stop body that covers the ends from the longitudinal direction of the gutter sections, and a stop body that is fixed to each of the ends of the two gutter sections. <1> and a gutter member according to the above, wherein the second direction of the gutter member is oriented in the longitudinal direction of the gutter. Effect of the Invention

[0011] According to the gutter member or gutter structure of the present invention, it is possible to provide a gutter member and a gutter structure that can suppress the outflow of water to the outside of the gutter. [Brief description of the drawings]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0013] Hereinafter, a rain gutter structure 60 and a rain gutter member 8 according to one embodiment of the present invention will be described with reference to the drawings. In the embodiment, as shown in Fig. 1, a direction away from the house starting from the eaves 16 of a building provided with a folded plate roof 15 is described as "forward," and a direction approaching the exterior wall of the building starting from the eaves 16 is described as "rearward."

[0014] [First embodiment] As shown in Figs. 1 and 2, the gutter structure 60 includes gutter members 2, 3 whose open ends face each other, and a gutter stop structure 1 provided between the two gutter members 2, 3. The two rain gutters 2, 3 include a first rain gutter (rain gutter) 2 and a second rain gutter (rain gutter) 3. The first rain gutter 2 and the second rain gutter 3 are arranged in opposing positions along the longitudinal direction with a gap between them. The first rain gutter 2 and the second rain gutter 3 are formed symmetrically to each other in the longitudinal direction.

[0015] As shown in Fig. 2, both the first rain gutter 2 and the second rain gutter 3 (hereinafter also referred to as rain gutters 2, 3) are supported by supports 12 in a longitudinally extending state, for example, by multiple rain gutter bodies 10 connected by joints (eaves joints) 11. The supports 12 are attached to the eaves end 16. In the rain gutters 2, 3, the multiple rain gutter bodies 10 extending in the longitudinal direction are supported by the supports 12 below the folded-plate roof 15.

[0016] As shown in Figs. 1 to 3, the gutter body 10 is made of, for example, a resin material. The gutter body 10 may be made of, for example, an oriented thermoplastic resin sheet or a vinyl chloride resin molding. The thickness of the gutter body 10 may be 0.7 to 1.8 mm. The gutter body 10 has a front wall (outer plate) 22 rising from the front side of the bottom plate 21, and a rear wall (inner plate) 23 rising from the rear side of the bottom plate 21. The gutter body 10 is formed with a U-shaped cross section by the bottom plate 21, the front wall 22, and the rear wall 23, and the height of the front wall 22 is formed slightly (for example, less than 1.5 times) higher than the height of the rear wall 23. However, the height of the front wall 22 and the height of the rear wall 23 may be equal, or the height of the front wall 22 may be lower than the height of the rear wall 23.

[0017] Furthermore, the gutter body 10 has a front ear 24 that protrudes forward from the upper side of the front wall 22, and a rear ear 25 that protrudes rearward from the upper side of the rear wall 23. Furthermore, a front reinforcing portion 27 is formed on the front ear 24 that protrudes forward, and a rear reinforcing portion 28 is formed on the rear ear 25 that protrudes rearward. Note that these front ear 24, rear ear 25, front reinforcing portion 27, and rear reinforcing portion 28 may be omitted.

[0018] The gutter body 10 has a width dimension W of the bottom plate 21 set to preferably 100 mm or more, more preferably 130 mm or more, and even more preferably 150 mm or more. The gutter body 10 has a width dimension W of the bottom plate 21 set to preferably 400 mm or less, more preferably 300 mm or less, and even more preferably 200 mm or less.

[0019] In the folded-plate roof 15, the eaves 16 may have a large projection dimension. Therefore, it is conceivable that the eaves 16 may project above the rain gutters 2, 3. Therefore, as described above, the height of the front wall 22 is formed slightly higher than the height of the rear wall 23, and the height of the rear wall 23 is kept low. This allows the rear wall 23 to be positioned at a predetermined distance below the folded-plate roof 15. On the other hand, by forming the height of the front wall 22 slightly higher than the height of the rear wall 23, for example, the appearance can be ensured.

[0020] As shown in FIGS. 1 and 4, the gutter stop structure 1 includes a first stop 5, a second stop 6, and a gutter member 8. The first stop 5 is a stopper member. As shown in Fig. 4, the first rain gutter 2 and the second rain gutter 3 have a first stop 5 and a second stop 6 fixed to each of two opposing open ends (ends) 2a, 3a. The first stop 5 and the second stop 6 are members formed approximately symmetrically in the longitudinal direction. Therefore, the same reference numerals are used to denote the respective components of the first stop 5 and the second stop 6, and the first stop 5 will be described in detail below, while a detailed description of the second stop 6 will be omitted.

[0021] The first stop 5 is formed of, for example, a resin material. The first stop 5 may be formed of, for example, a resin such as polyvinyl chloride, asphalt, or the like, and a highly weather-resistant special resin such as AES resin may be used as a surface layer. The first stop 5 may also be made of a metal such as a stainless steel plate. As shown in Fig. 4, the first stop 5 covers the open end of the gutter body 10 (i.e., the open end 2a of the first gutter 2) from the outside in the longitudinal direction of the gutter body 10. The first stop 5 is plate-shaped. When the gutter body 10 is viewed in the longitudinal direction, the first stop 5 and the open end of the gutter body 10 have the same shape and size.

[0022] The outer periphery of the first stop 5 is formed with a groove recessed along the longitudinal direction toward the opposite side of the gutter body 10 (hereinafter also referred to as the opposite side of the gutter). The groove is provided around the entire outer periphery of the stop body 30. As a result, a portion of the stop body 30 located on the inside of the groove forms a protrusion 31 that protrudes along the longitudinal direction toward the gutter body 10 (hereinafter also referred to as the gutter side). The protrusion 31 is formed in a generally rectangular shape so that it can be fitted into the open end of the gutter body 10 (i.e., the open end 2a of the first gutter 2).

[0023] As a result, the opening end 2a of the first eaves gutter 2 is blocked by the first stop 5. Therefore, the first stop 5 can prevent the rainwater inside the first eaves gutter 2 from spilling out from the opening end 2a. This allows the rainwater collected inside the first eaves gutter 2 to flow out of the downspout (not shown).

[0024] As shown in FIG. 4, a gutter member 8 is bridged over the first end 5 and the second end 6 (specifically, the eaves portion 38 of the first end 5 and the eaves portion 38 of the second end 6).

[0025] The gutter member 8 in this embodiment will be described. As shown in FIGS. 5 to 9, the gutter member 8 has a main body portion 51, a first piece 52, and a second piece .

[0026] Hereinafter, when the gutter member 8 is installed on the upper part of the retaining body 30, the direction corresponding to the front-to-rear direction is defined as a first direction A of the gutter member 8, and the direction perpendicular to the first direction A and corresponding to the extension direction of the gutter is defined as a second direction B of the gutter member 8. In addition, when the gutter member 8 is installed on the upper part of the retaining body 30, the side corresponding to the front (top) of the main body part 51 is defined as a first side D1, and the side corresponding to the back (bottom) of the main body part 51 is defined as a second side D2.

[0027] The main body 51 is rectangular in plan view, and has two first sides 53 facing the first direction A and two second sides 55 facing the second direction B. In this embodiment, the main body 51 is rectangular. Note that the main body 51 is not limited to a rectangular shape. For example, the main body 51 may be square, some or all of the sides of the main body 51 may be curved, and some or all of the corners of the main body 51 may be arc-shaped.

[0028] The main body 51 is placed on the eaves 38 of the first stop 5 and the eaves 38 of the second stop 6, and is bridged over the eaves 38. The main body 51 has three holes 56. The number of holes 56 in the main body 51 is not limited, and may be one or more. The holes 56 are provided for placing screws (penetrating members) 58. In this embodiment, the gutter member 8 is fixed only to the eaves 38 of the second stop 6 with screws 58 (three screws 58 in the illustrated example). That is, the gutter member 8 is fixed only to one of the two second stops 6, the first stop 5 and the second stop 6, with three screws 58, and is not fixed to the other first stop 5. The holes 56 are arranged on the eaves 38 of the second stop 6. This allows the gutter 2 having the first end 5 and the gutter 3 having the second end 6 equipped with the gutter member 8 to be fixed to the roof.

[0029] Due to changes in environmental temperature, etc., the opposing first rain gutter 2 and second rain gutter 3 may expand and contract in the longitudinal direction, causing the distance between the opening end 2a of the first rain gutter 2 and the opening end 3a of the second rain gutter 3 to change in the longitudinal direction. When the rain gutter member 8 is fixed with screws 58 on only one side, in addition to improving workability and reducing costs, it is possible to allow the first eaves gutter 2 and second eaves gutter 3 to expand and contract in the longitudinal direction. The main body 51 does not have to have holes.

[0030] As shown in FIG. 5, the main body 51 includes a first piece 52 extending from at least one of the two first sides 53 to the first side D1, and the width of the first piece 52 in the second direction B is greater than the width of the main body 51 in the second direction B. Specifically, as shown in FIG. 6, when the width of the first piece 52 in the second direction B is length L1 and the width of the main body 51 in the second direction B is length L2, L1>L2. This allows the first piece 52 to be extended from the main body 51 in the second direction B, which is the direction of water flow. In this case, the length L3 of the extension of the first piece 52 may be equal to the difference between the length L1 and the length L2. The lower limit of the length L3 of the extension of the first piece 52 is preferably 20 mm, more preferably 25 mm. If the lower limit of the length L3 of the extension of the first piece 52 is equal to or greater than a predetermined lower limit, the extension of the first piece 52 functions as a drain. The upper limit of the length L3 of the extension of the first piece 52 is not particularly limited, but from the viewpoint of workability and cost, it is preferably 50 mm, more preferably 40 mm. The length L2 of the main body 51 in the second direction B is preferably 100 mm or more, more preferably 130 mm or more. The length L2 of the main body 51 in the second direction B is preferably 200 mm or less, more preferably 160 mm or less.

[0031] In this embodiment, the angle α between the main body 51 and the first piece 52 is an acute angle when the gutter member 8 is viewed from the second direction B. The angle α refers to the angle between the surface of the first side D1 of the main body 51 and the first piece 52, among the angles between the main body 51 and the first piece 52 when the gutter member 8 is viewed from the second direction B. The upper limit of the angle α is preferably 80°, and more preferably 70°. If the upper limit of the angle α is equal to or less than a predetermined upper limit, the outflow of water to the outside of the gutter due to splashing can be sufficiently suppressed. On the other hand, if the angle α is excessively small, the first piece 52 is formed to be excessively tilted, which reduces the function of the wall that suppresses the outflow of water, making it difficult to suppress the outflow of water to the outside of the gutter. Therefore, the lower limit of the angle α is preferably 30°, and more preferably 45°.

[0032] In this embodiment, the gutter member 8 includes second pieces 54 extending from the two second sides 55 of the main body 51 to the second side D2. This allows the second pieces 54 to be hooked onto the stop eaves portion 38 provided on the gutter. 4 and 5, the second piece 54 may have an L-shape facing inward in the second direction B when the gutter member 8 is viewed from the first direction A. With this structure, the second piece 54 can be hooked onto the stop eaves portion 38 provided on the gutter, and the positioning of each gutter can be easily performed when installing the gutter on the roof. Also, even if vibrations are applied vertically due to an earthquake or the like, the second piece 54 can be shaped to be unlikely to come off the eaves portion 38, and the gutter member 8 can be prevented from shifting from the stop eaves portion 38.

[0033] In this embodiment, the gutter member 8 is produced by cutting a metal plate into a predetermined shape and then bending it at a predetermined position. When the gutter member 8 is unfolded, the width in the second direction B including the main body 51 and the second piece 54 is preferably equal to or greater than the width in the second direction B of the first piece 52. If the width in the second direction B including the main body 51 and the second piece 54 is greater than the width in the second direction B of the first piece 52, when the gutter member 8 is cut out as a unit from a single rectangular steel plate, both ends of the first piece 52 in the second direction B can be trimmed by the amount that the width of the first piece 52 is shorter. The method for producing the gutter member 8 is not limited to the above.

[0034] This allows the gutter member 8 to prevent rainwater from leaking downward and dripping between the first stop 5 and the second stop 6 (i.e., between the opposing first gutter 2 and second gutter 3). Note that at least one of the two first pieces 52 is sufficient, and some or all of the two second pieces 54 may be missing.

[0035] As described above, the gutter structure 60 of this embodiment is rectangular in a plan view and comprises a main body 51 having two first sides 53 facing a first direction A and two second sides 55 facing a second direction B, and a first piece 52 extending from at least one of the two first sides 53 of the main body 51 to the first side D1, and the width of the first piece 52 in the second direction B is greater than the width of the main body 51 in the second direction B. With this structure, the length of first piece 52 can be extended in second direction B, which is the direction of water flow, beyond the length of main body 51. Therefore, the extended portion of first piece 52 functions as a drainage section, and it is possible to prevent water from flowing out of the gutter from the end of first piece 52 due to the water flow. Therefore, it is possible to prevent water from flowing out of the gutter and to increase the allowable water volume.

[0036] Furthermore, in the gutter member 8 of this embodiment, when the gutter member 8 is viewed from the second direction B, the angle α between the main body 51 and the first piece 52 is an acute angle. With this structure, the angle α between the main body 51 and the first piece 52 is an acute angle. This makes it possible to suppress water splashing that occurs when water collides with the first piece 52. Therefore, even when the amount of drainage is large and the water flow rate is fast, it is possible to suppress water from climbing over the first piece 52. This makes it possible to suppress water from flowing out of the gutter and to increase the allowable amount of drainage.

[0037] Furthermore, the gutter member 8 of this embodiment has at least one hole 56 in the main body 51. With this, by placing a penetrating member in the hole 56, the gutter member 8 can be easily fixed in a stable state to the upper end of the basin. Therefore, even when there is a large amount of water and the water flow is strong, the gutter member 8 can be prevented from coming off the upper end of the basin. This makes it possible to prevent water from flowing out of the gutter and to increase the allowable water volume.

[0038] The gutter member 8 of the present embodiment further includes a second piece 54 extending from the two second edges 55 to the second side D2. This allows the second piece 54 to be hooked onto the stop eaves portion 38 provided on the gutter, thereby preventing the gutter member 8 from shifting from the stop eaves portion 38.

[0039] The technical scope of the present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the present invention.

[0040] Holes 56 into which the screws 58 are inserted may be formed in advance in the gutter member 8 and the eaves portion 38. Conversely, the gutter member 8 and the eaves portion 38 may not have holes 56. In this case, when the gutter member 8 is fixed to the eaves portion 38, the screws 58 may penetrate the portions of the gutter member 8 and the eaves portion 38 that do not have holes 56. An adhesive may be used in place of the screws 58. The gutter member 8 may be fixed to both of the two stops 5,6.

[0041] In addition, within the scope of the invention, the components in the above-described embodiments may be replaced with well-known components, and the above-described modified examples may be combined as appropriate. [Explanation of symbols]
