Description

[Technical Field]

[0001] The present invention relates to an eaves gutter structure. [Background Art]

[0002] Conventionally, there has been known a structure in which an end cap is fixed to an open end of an eaves gutter. With this structure, the end cap can prevent rainwater inside the eaves gutter from spilling out from the open end (see, for example, Patent Document 1). [Prior Art Documents] [Patent Documents]

[0003] [Patent Document 1] Japanese Unexamined Patent Publication No. 2004-285601 [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] In conventional eaves gutters, a gap is provided between mutually opposing end caps respectively arranged at the ends of two adjacent eaves gutters, which means rainwater may drip down through the gap between the two end caps. To address this, it has been considered to provide a bridging member for receiving rainwater flowing down between the two end caps at upper portions of the two end caps. However, such a bridging member is easily displaced under wind force, so it is required to be fixed to the end caps or other components.

[0005] The present invention has been made in view of the circumstances described above, and an object of the present invention is to provide an eaves gutter structure that allows easy fixing of the bridging member. [Means for Solving the Problem]

[0006] In order to solve the above problem, the present invention proposes the following means. <1> A gutter structure according to one aspect of the present invention is a gutter structure having two gutters whose ends face each other, and a stop structure provided between the ends of the gutters, wherein the stop structure comprises a stop body that covers the end from the longitudinal direction of the gutter, a bottom portion, a front wall portion and a rear wall portion provided on the gutter side from the stop body, an overhang portion positioned at the upper end of the stop body, and a bridging member that spans over the two stop bodies fixed to each of the ends of the two gutters.

[0007] In this case, the canopy section was placed at the upper end of the stop, and the connecting member was fixed to the canopy section. This allows the connecting member to be easily and stably fixed to the canopy section (i.e., the upper end of the stop).

[0008] <2> the above <1> In the gutter structure relating to this, a configuration in which a notch is formed in the eaves portion may be adopted.

[0009] In this case, a notch was formed in the eaves section. Therefore, rainwater can be directed from the notch into the gutter. As a result, it is possible to prevent rainwater from dripping from the eaves section down the outside of the gutter.

[0010] <3> the above <1> or <2> In the gutter structure relating to this, the upper surface of the eaves portion may be configured to have a sloping surface that slopes downward toward the inside of the gutter.

[0011] In this case, rainwater that falls on the eaves can be directed into the gutter by the sloping surface.

[0012] <4> the above <1> from <3> In the gutter structure relating to this, the gutter may be configured such that the width of the bottom plate is 200 mm or more.

[0013] In general, gutters with a base plate width of 200 mm or more are classified as large gutters used for non-residential buildings such as commercial facilities. That is, by making the base plate width of the gutters 200 mm or more, the end cap is suitably applied to large gutters used for non-residential buildings such as commercial facilities.

[0014] <5>In the eaves gutter structure according to any one of <1> to <4> above, a configuration may be adopted in which the bridging member is fixed to only one of the two stoppers and is not fixed to the other.

[0015] Here, for example, in the case of resin eaves gutters, it is conceivable that mutually opposing eaves gutters expand and contract in the longitudinal direction due to changes in environmental temperature and the like. Therefore, the bridging member is fixed to only one of the two stoppers and is not fixed to the other. Accordingly, the two stoppers can be moved in the longitudinal direction of the eaves gutters. This allows expansion and contraction of the eaves gutters to be accommodated by moving the two stoppers in the longitudinal direction of the eaves gutters when the mutually opposing eaves gutters expand or contract.

[0016] <6>An eaves gutter structure according to one aspect of the present invention is an eaves gutter structure comprising an upper eaves gutter, two lower eaves gutters whose ends face each other, and a stopper structure provided between the ends of the lower eaves gutters, wherein the stopper structure includes: stopper bodies that cover the ends from the longitudinal direction of the lower eaves gutters; a bridging member that is bridged over the two stopper bodies respectively fixed to the ends of the two lower eaves gutters; and a penetrating member that is provided on the bridging member and into which a downspout connected to the upper eaves gutter is inserted.

Effects of the Invention

[0017] According to the present invention, an eaves gutter structure in which a bridging member can be easily fixed can be provided.

[0019] Hereinafter, an eaves gutter end structure, an end plug, and an eaves gutter according to an embodiment of the present invention will be described with reference to the drawings. In the embodiment, with the eave tip 16 of a building provided with a folded-plate roof 15 as a starting point, the direction away from the house is described as "front", and the direction approaching the house with the eave tip 16 as a starting point is described as "rear".

[0020] [First Embodiment] As shown in Figures 1 and 2, the gutter structure 60 comprises two gutters 2 and 3 with their open ends facing each other, and a gutter end structure 1 provided between the two gutters 2 and 3. The two eaves gutters 2 and 3 consist of a first eaves gutter 2 and a second eaves gutter 3. The first eaves gutter 2 and the second eaves gutter 3 are spaced apart and positioned opposite each other along their respective longitudinal directions. The first eaves gutter 2 and the second eaves gutter 3 are formed symmetrically to each other in the longitudinal direction.

[0021] As shown in Figure 2, both the first gutter 2 and the second gutter 3 (hereinafter also referred to as gutters 2 and 3) are supported by a support 12 in a state where they extend in the longitudinal direction, for example, by connecting multiple gutter bodies 10 with joints (eave joints) 11. The support 12 is attached to the eaves 16. In gutters 2 and 3, multiple gutter bodies 10 extending in the longitudinal direction are supported by the support 12 below the corrugated metal roof 15.

[0022] As shown in Figures 1 to 3, the gutter body 10 is made of, for example, a resin material. The gutter body 10 has a front wall (outer plate) 22 rising from the front edge of the bottom plate 21, and a rear wall (inner plate) 23 rising from the rear edge of the bottom plate 21. The gutter body 10 is formed in a U-shape in cross-section by the bottom plate 21, the front wall 22, and the rear wall 23, with the height of the front wall 22 being slightly (for example, less than 1.5 times) higher than the height of the rear wall 23. However, the heights of the front wall 22 and the rear wall 23 may be the same, or the height of the front wall 22 may be lower than the height of the rear wall 23.

[0023] Furthermore, the gutter body 10 has a front ear 24 that extends forward from the upper edge of the front wall 22, and a rear ear 25 that extends backward from the upper edge of the rear wall 23. In addition, a front reinforcing part 27 is formed inside the gutter body 10 at the intersection of the bottom plate 21 and the front wall 22, and a rear reinforcing part 28 is formed inside the gutter body 10 at the intersection of the bottom plate 21 and the rear wall 23. Note that these front ears 24, rear ears 25, front reinforcing part 27, and rear reinforcing part 28 are optional.

[0024] The gutter body 10 preferably has a base plate width W of 200 mm or more, more preferably greater than 200 mm, and even more preferably 300 mm or more. Here, generally, gutters 2 and 3 with a base plate width of 200 mm or more are classified as large gutters used for non-residential buildings such as commercial facilities. In other words, gutters 2 and 3 are preferably large gutters used for non-residential buildings such as commercial facilities. In this case, the gutter end structure 1 is applied to large gutters used for non-residential buildings such as commercial facilities. Note that the width W may be less than 200 mm.

[0025] In the case of corrugated metal roofs 15 for non-residential buildings, the overhang of the eaves 16 may be large. Therefore, it is conceivable that the eaves 16 may protrude above the gutters 2 and 3. To address this, as mentioned above, the height of the front wall 22 is made 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 below the corrugated metal roof 15 at a predetermined interval. On the other hand, by making the height of the front wall 22 slightly higher than the height of the rear wall 23, for example, aesthetic appearance can be ensured.

[0026] As shown in Figures 1 and 4, the gutter end structure 1 comprises a first end (end) 5, a second end (end) 6, and a connecting member 8. As shown in Figure 4, the first gutter 2 and the second gutter 3 each have two opposing open ends (ends) 2a and 3a, to which two stoppers, the first stopper 5 and the second stopper 6, are fixed. The first stopper 5 and the second stopper 6 are members formed to be approximately symmetrical in the longitudinal direction. Therefore, the same reference numerals are used for each component of the first stopper 5 and the second stopper 6 below, the first stopper 5 will be described in detail, and a detailed description of the second stopper 6 will be omitted.

[0027] As shown in Figures 5 to 7, the first stop 5 is made of, for example, a resin material. The first stop 5 has a stop body 30, a bottom portion 32, a front wall portion 33, a rear wall portion 34, a groove portion 35, a front ear receiving portion 36, a rear ear receiving portion 37, and a canopy portion (fixed portion) 38. The end cap 30 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 end cap 30 is plate-shaped. When the gutter body 10 is viewed from the longitudinal direction, the end cap 30 and the open end of the gutter body 10 are of the same shape and size.

[0028] The outer circumference of the end cap body 30 has a groove 35 formed along its longitudinal direction that is recessed toward the opposite side of the gutter body 10 (hereinafter also referred to as the opposite side of the gutter). The groove 35 is provided around the entire circumference of the outer edge of the end cap body 30. As a result, the portion of the end cap body 30 located inside the groove 35 forms a convex portion 31 that protrudes toward the gutter body 10 side (hereinafter also referred to as the gutter side) along its longitudinal direction. The convex portion 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).

[0029] The top surface of the protrusion 31 has a base 31a, a front side 31b, a rear side 31c, and a top side 31d. The base 31a, front side 31b, and rear side 31c are formed in a U-shape that opens upward. The bottom portion 32, front wall portion 33, and rear wall portion 34 are formed at intervals outward from the base 31a, front side 31b, and rear side 31c, respectively. The bottom portion 32, front wall portion 33, and rear wall portion 34 are formed in a U-shape. The bottom portion 32, front wall portion 33, and rear wall portion 34 extend from the outer peripheral edge of the end cap body 30 toward the gutter side. The groove portion 35 described above is formed between the base 31a and the bottom portion 32, between the front side 31b and the front wall portion 33, and between the rear side 31c and the rear wall portion 34.

[0030] Furthermore, if the width dimension W of the bottom plate 21 of the gutter body 10 is 200 mm or more, the bottom portion 32 is made to have a width dimension exceeding 200 mm, and it is preferable that it be made to exceed 300 mm to match the width dimension of the bottom plate 21 of the gutter body 10.

[0031] A front recess 41 is formed at the front lower convex corner of the groove 35, which can be fitted onto the end of the front reinforcing portion 27. Additionally, a rear recess 42 is formed at the rear lower convex corner of the U-shaped groove 35, which can be fitted onto the end of the rear reinforcing portion 28. An anterior ear support portion 36 is formed at the upper end of the anterior wall portion 33. The anterior ear support portion 36 extends forward from the upper end of the anterior wall portion 33. A posterior ear support portion 37 is formed at the upper end of the posterior wall portion 34. The posterior ear support portion 37 extends backward from the upper end of the posterior wall portion 34.

[0032] When fixing the first end cap 5 to the first gutter 2, for example with adhesive, the open end 2a of the first gutter 2 is fitted into the groove 35, and the protrusion 31 of the end cap body 30 is fitted into the open end 2a. The front recess 41 is fitted into the end of the front reinforcement 27. Furthermore, the rear recess 42 is fitted into the end of the rear reinforcement 28. In addition, the front ear receiving portion 36 is positioned below the end of the front ear 24. Furthermore, the rear ear receiving portion 37 is positioned below the end of the rear ear 25.

[0033] As a result, the opening end 2a of the first gutter 2 is blocked by the first stopper 5. Therefore, the first stopper 5 prevents rainwater inside the first gutter 2 from spilling out from the opening end 2a. This allows the rainwater collected inside the first gutter 2 to flow out through a downpipe (not shown).

[0034] Furthermore, the upper part of the stop body 30 of the first stop 5 (hereinafter also referred to as the upper part 30a of the stop body) is formed with an upward slope from rear to front, and the top edge 31d of the protrusion 31 is formed with an upward slope from the rear end 31e to the front end 31f. A canopy portion 38 is formed on the upper edge of the upper part 30a of the stop body, spaced upward (outward) from the top edge 31d of the protrusion 31. In other words, the canopy portion 38 is positioned at the upper end of the first stop 5. The canopy portion 38 is formed with an upward slope from rear to front along the upper edge of the upper part 30a of the stop body. The canopy portion 38 is also positioned above the opening end 2a of the first gutter 2.

[0035] Furthermore, the canopy portion 38 has, for example, a horizontally formed front end 38b. In the front-rear direction, the canopy portion 38 has a front notch (cutout) 45 formed between the front end 38b and the projection 36a of the front ear support portion 36. The front notch 45 is positioned above the front ear support portion 36. The front notch 45 communicates with the inside of the opening end 2a (the inside of the first gutter 2) via the front ear support portion 36.

[0036] Furthermore, the canopy portion 38 has, for example, a rear end 38a that is formed horizontally. In the front-rear direction, the canopy portion 38 has a rear notch (notch) 46 formed between the rear end 38a and the projection 37a of the rear ear support portion 37. The rear notch 46 is positioned above the rear ear support portion 37. The rear notch 46 communicates with the inside of the opening end 2a (the inside of the first gutter 2) via the rear ear support portion 37.

[0037] Furthermore, the upper surface of the eaves portion 38 may be a sloping surface that descends from the opposite side of the gutter towards the gutter side (i.e., inside the gutter). In this case, rainwater that falls on the eaves portion 38 can be directed into the inside of the gutter body 10. Furthermore, in Figures 5 to 7, the canopy portion 38 is provided to protrude from the upper part 30a of the end cap body toward the gutter side, but it may also protrude from the upper part 30a of the end cap body toward the opposite side of the gutter. In this case, rainwater can be directed into the gutter body 10 without providing notches (front notches 45 and rear notches 46) in the canopy portion 38. Moreover, in this case, it is easier for the worker to grasp the canopy portion 38 when installing the end cap (first end cap 5). The canopy portion 38 may also protrude from the upper part 30a of the end cap body toward both sides in the longitudinal direction (both the gutter side and the opposite side of the gutter). In other words, the canopy portion 38 can be appropriately configured to extend longitudinally from the end cap body 30.

[0038] As described above, the visor portion 38 is positioned at the upper end of the first stop 5. Furthermore, the front notch 45 formed in the visor portion 38 is connected to the inside of the open end 2a via the front ear receiving portion 36. In addition, the rear notch 46 formed in the visor portion 38 is connected to the open end 2a via the rear ear receiving portion 37. Therefore, rainwater can be directed from the front notch 45 and the rear notch 46 into the interior of the first gutter 2. This prevents rainwater from dripping from the eaves 38 down to the outside of the first gutter 2. In particular, when the same shape of stoppers is used at the open ends 2a of the second gutter 2 and the open ends 3a of the third gutter 3, where the ends of the two gutters 2 and 3 do not face each other and a connecting member 8 is not provided, rainwater that falls on the upper surface of the eaves 38 can be directed from the front notch 45 and the rear notch 46 into the interior of the gutter body 10. In the illustrated example, the front notch 45 and the rear notch 46 are not covered by the connecting member 8, but they may be covered.

[0039] As shown in Figures 4 and 8, a bridge member 8 is stretched across two of the first stop 5 and the second stop 6 (specifically, the canopy portion 38 of the first stop 5 and the canopy portion 38 of the second stop 6). The bridge member 8 has a bridge body 51, a front upright piece 52, a rear upright piece 53, a first downward piece 54, and a second downward piece 55.

[0040] The bridge body 51 is formed in a rectangular shape in plan view. The bridge body 51 is placed on the canopy portion 38 of the first stop 5 and the canopy portion 38 of the second stop 6 and spans across each canopy portion 38. The bridge body 51 is fixed to the canopy portion 38 of the second stop 6 only with screws 58 (a pair of screws 58 in the illustrated example). That is, the bridge member 8 is fixed to the second stop 6 of the two stops 5 and the second stop 6 only with a pair of screws 58, and is not fixed to the other stop 5.

[0041] Here, the canopy portion 38 is formed with an upward slope from the rear end 38a to the front end 38b. Therefore, the portion 38c of the canopy portion 38 located below the corrugated metal roof 15 can be positioned at a predetermined distance from the corrugated metal roof 15. This allows, for example, a tool for attaching screws 58 to be placed at the aforementioned predetermined distance. Consequently, the work of fixing the main body 51 to the canopy portion 38 of the second end 6 with screws 58 can be easily carried out.

[0042] Next, I will explain why the connecting member 8 is fixed only to one of the second stops 6 and not to the other first stop 5. In other words, for example, in the case of a first gutter 2 and a second gutter 3 made of resin, it is conceivable that the first gutter 2 and the second gutter 3, which face each other, may expand or contract in the longitudinal direction due to changes in ambient temperature, etc. As the first gutter 2 and the second gutter 3 expand or contract in the longitudinal direction, the distance between the open end 2a of the first gutter 2 and the open end 3a of the second gutter 3 changes in the longitudinal direction.

[0043] Therefore, the connecting member 8 was fixed only to the second stop 6 and not to the first stop 5. Thus, the first gutter 2 and the second gutter 3 can be moved independently (without interfering with each other) in the longitudinal direction of the first gutter 2 and the second gutter 3. As a result, when the opposing first gutter 2 and the second gutter 3 expand or contract, the first stop 5 and the second stop 6 can be moved in the longitudinal direction of the first gutter 2 and the second gutter 3. Thus, by fixing the connecting member 8 only to the second stop 6 and not to the first stop 5, expansion and contraction in the longitudinal direction of the first gutter 2 and the second gutter 3 can be permitted.

[0044] Here, the connecting member 8 is fixed to the canopy portion 38 of the second stop 6 with screws 58 and rests on the canopy portion 38 of the first stop 5. This allows the connecting member 8 to be fixed stably to the upper ends of both the first stop 5 and the second stop 6.

[0045] In this state, the bridge body 51 is formed with an upward slope from the rear edge 51a to the front edge 51b along the canopy portion 38 of the first stop 5 and the canopy portion 38 of the second stop 6. Furthermore, the front edge 51b of the bridge body 51 is located behind the front end 38b of each canopy portion 38. In addition, the rear edge 51a of the bridge body 51 is located in front of the rear end 38a of each canopy portion 38 (only the rear end 38a of the canopy portion 38 of the first stop 5 is shown in Figure 5). In other words, the first horizontal side 51c of the main body 51 is located above the opening end 2a of the first gutter 2. Also, the second horizontal side 51d of the main body 51 is located above the opening end 3a of the second gutter 3.

[0046] The front upright piece 52 rises upward from the front edge 51b of the main bridge body 51. The front upright piece 52 is positioned behind the front end 38b of each canopy section 38. The rear upright piece 53 rises upward from the rear edge 51a of the main bridge body 51. The rear upright piece 53 is positioned in front of the rear end 38a of each canopy section 38 (Figure 5 shows only the rear end 38a of the canopy section 38 of the first stop 5).

[0047] The first downward-facing piece 54 hangs downward from the first horizontal side 51c of the main bridge body 51. The first downward-facing piece 54 is located above the opening end 2a of the first gutter 2. The second downward-facing piece 55 hangs downward from the second horizontal side 51d of the main bridge body 51. The second downward-facing piece 55 is located above the opening end 3a of the second gutter 3.

[0048] In this manner, the connecting member 8 is fixed in a state where it is stretched across the canopy portion 38 of the first end 5 and the canopy portion 38 of the second end 6. Furthermore, the front upright piece 52 is positioned behind the front end 38b of each canopy portion 38. In addition, the rear upright piece 53 is positioned in front of the rear end 38a of each canopy portion 38 (only the rear end 38a of the canopy portion 38 of the first end 5 is shown in Figure 5). Furthermore, the first downward piece 54 is positioned above the open end 2a of the first gutter 2. Furthermore, the second downward piece 55 is positioned above the open end 3a of the second gutter 3.

[0049] This prevents rainwater from leaking downwards and dripping down between the first stop 5 and the second stop 6 (i.e., between the first gutter 2 and the second gutter 3 which are opposite to each other) using the connecting member 8. Note that some or all of the front upright piece 52, the rear upright piece 53, the first downward piece 54, and the second downward piece 55 may be omitted.

[0050] As described above, according to the gutter structure 60 of the first embodiment, the open end 2a of the first gutter 2 and the open end 3a of the second gutter 3 are positioned opposite each other. Furthermore, the first stopper 5 is fixed to the open end 2a of the first gutter 2, and the open end 2a of the first gutter 2 is closed by the first stopper 5. In addition, the second stopper 6 is fixed to the open end 3a of the second gutter 3, and the open end 3a of the second gutter 3 is closed by the second stopper 6. This prevents rainwater collected inside the first gutter 2 and the second gutter 3 from spilling out through their respective opening ends 2a and 3a, which is then prevented by the first stopper 5 and the second stopper 6.

[0051] Furthermore, a connecting member 8 is placed across the respective eaves 38 of the adjacent first gutter 2 and second gutter 3. This prevents rainwater from leaking downwards and dripping down between the adjacent first stop 5 and second stop 6 (i.e., between the first gutter 2 and second gutter 3 that are opposite to each other).

[0052] [Second Embodiment] The gutter end structure 100 of the second embodiment will be described below with reference to Figures 9 to 11. In the second embodiment, the same or similar parts as those of the gutter end structure 1 of the first embodiment are denoted by the same reference numerals, and detailed explanations will be omitted.

[0053] As shown in Figures 9 to 11, the gutter end structure 100 is modified in which the first end 5 and connecting member 8 of the first embodiment are replaced with the first end (end) 102 and connecting member 103, while the other configurations are the same as the gutter end structure 1 of the first embodiment. The first end 102 is modified in which the end body 30 and canopy portion 38 of the first embodiment are replaced with the end body 105 and canopy portion (fixed portion) 106.

[0054] The stopper body 105 has a horizontal section 105b and an inclined section 105c formed on the upper edge of the upper part 105a of the stopper body. The horizontal section 105b extends horizontally forward from the rear end 105d of the upper part 105a of the stopper body. The horizontal section 105b is positioned below the eaves 16 at a predetermined distance. The inclined section 105c extends upward from the front end 105e of the horizontal section 105b toward the front end 105f of the upper part 105a of the stopper body.

[0055] The canopy portion 106 is formed along the upper part 105a of the end cap body. Specifically, the canopy portion 106 has a horizontal canopy portion 106a and an inclined canopy portion 106b. The horizontal canopy portion 106a extends horizontally along the horizontal portion 105b. The horizontal canopy portion 106a is positioned below the eaves 16 at a predetermined distance. The inclined canopy portion 106b extends upward toward the front along the inclined portion 105c.

[0056] The bridging member 103 includes a bridging body 112, a front upright piece 52, a rear upright piece 53, a first downward piece 113, and a second downward piece 114. The bridging body 112 has a bridging horizontal section 112a, a bridging inclined section 112b, and a bridging front end 112c formed along the canopy horizontal section 106a, canopy inclined section 106b, and front end 106c of the canopy section 106. The bridging horizontal section 112a is positioned downward from the eaves 16 at a predetermined distance L. Here, since the bridging horizontal section 112a is formed horizontally, the entire bridging horizontal section 112a is positioned downward from the eaves 16 at a uniform predetermined distance L.

[0057] Furthermore, the first downward-facing piece 113 hangs downward from the first horizontal side of the horizontal bridge section 112a, the inclined bridge section 112b, and the front bridge end 112c, respectively. The second downward-facing piece 114 hangs downward from the second horizontal side of the horizontal bridge section 112a, the inclined bridge section 112b, and the front bridge end 112c, respectively.

[0058] The connecting member 103 is placed across the canopy portion 106 of the first stop 102 and the canopy portion (not shown) of the second stop, with the connecting body 112 resting on the canopy portion 106 of the first stop 102 and the canopy portion (not shown) of the second stop. The connecting member 103 is fixed to only the second stop of the two stops (the first stop 102) with a pair of screws (not shown), and is not fixed to the other stop 102 (the first stop).

[0059] Here, the entire horizontal section 112a of the connecting member 103 is positioned uniformly below the eaves 16 at a predetermined interval L. Therefore, tools for attaching screws (not shown) located below the eaves 16 can be placed at predetermined intervals. This makes it easy to fix the connecting body 112 to the second end of the canopy with screws.

[0060] Furthermore, the connecting member 103 is fixed to only one of the two end stops 102, the second end, with a pair of screws (not shown), and not to the other end stop 102. Therefore, when the opposing first gutter 2 and second gutter 3 (see Figure 2) expand and contract, the two end stops 102 and 2 can be moved in the longitudinal direction of the first gutter 2 and second gutter 3. This allows for expansion and contraction in the longitudinal direction of the first gutter 2 and second gutter 3.

[0061] Furthermore, the connecting member 103 was placed across the canopy portion 106 of the first stop 102 and the canopy portion (not shown) of the second stop. This prevents rainwater from leaking downwards and dripping from between the first stop 102 and the second stop.

[0062] (Third embodiment) The following describes a rain gutter (piping structure, eaves gutter structure) according to the third embodiment of the present invention with reference to Figures 12 to 15. As shown in Figure 12, the rain gutter 90 drains rainwater from a building 40, such as an apartment building. The building 40 has a roof 40a and an overhang 40b. The roof 40a has a slope. The canopy 40b is provided on the wall surface of the building 40 where the lower end of the slope of the roof 40a is located. The canopy 40b functions, for example, as a rain cover for openings in the building 40 (e.g., windows or entrances (front doors)). The canopy 40b may also function as a balcony in an apartment building.

[0063] As shown in Figures 12 and 13, the rain gutter 90 comprises an upper gutter 91, lower gutters 92 and 93, a drainage member 94, a through member 95, and a connecting member 80. The gutter end structure 1 in this embodiment includes a first end 5, a second end 6, a connecting member 80, and a through member 95. The upper gutter 91 drains rainwater that falls on the roof 40a. The upper gutter 91 is positioned, for example, at the eaves of the roof 40a. In the following, the direction in which the upper gutter 91 extends is referred to as the first horizontal direction. The upper gutter 91 comprises a bottom portion 91a and two side portions 91b. The bottom portion 91a is a flat plate with a drainage slope. The two side portions 91b are located at both ends of the bottom portion 91a in the width direction. The side portions 91b extend upward from the bottom portion 91a.

[0064] The lower gutter 92 drains rainwater that falls on the eaves 40b. The lower gutter 92 is positioned, for example, between the wall of the building 40 and the eaves 40b. The lower gutter 92 extends in a first horizontal direction. The lower gutter 92 is shorter than the upper gutter 91 in the first horizontal direction. The lower gutter 92 is located directly below the upper gutter 91. The lower gutter 92 comprises a bottom portion 92a and two side portions 92b. The bottom portion 92a is a flat plate with a drainage slope. The two side portions 92b are located at both ends of the bottom portion 92a in the width direction. The side portions 92b extend upward from the bottom portion 92a. In this embodiment, the lower gutter 92 corresponds to the first gutter 2 and the second gutter 3 in the first embodiment, and, similar to the first embodiment, the end-stop structure 1 comprises a first end-stop 5, a second end-stop 6, and a connecting member 80.

[0065] The downpipe 93 extends downward from the upper gutter 91. The downpipe 93 discharges the drainage from the upper gutter 91 downward. Multiple downpipes 93 are provided at intervals in the first horizontal direction. The interval between the downpipes 93 in the first horizontal direction is, for example, 30m or less. The distance in the first horizontal direction from the outermost downpipe 93 of the multiple downpipes 93 to the end (dead end) of the upper gutter 91 is, for example, 15m or less. The height of the downpipe 93 is, for example, 2m or more, preferably 3m or more.

[0066] The drainage member 94 is located inside the upper gutter 91. The drainage member 94 penetrates the bottom 91a of the upper gutter 91. The drainage member 94 has a high drainage function to improve the drainage capacity of rainwater that flows into the gutter during heavy rain. The drainage flow rate per unit area of ​​the drainage member 94 is, for example, 0.25 L / sec·cm. 2 Preferably, the flow rate is 0.30 L / sec·cm². 2 That's all.

[0067] The drainage member 94 is connected to the upper end of the downpipe 93. The drainage member 94 facilitates the smooth flow of water from the upper gutter 91 into the downpipe 93. In the rain gutter 90, for example, when the downpipe 93 becomes filled with rainwater, a siphon effect occurs, and a large amount of rainwater is drained from the gutter by the drainage member 94. At this time, the drainage member 94 does not obstruct the increase in the flow velocity of the rainwater due to the siphon effect, allowing a large amount of rainwater to be drained from the gutter into the downpipe 93. However, if the water from the downpipe 93 is allowed to flow into the lower gutter 92, there is a risk that the large amount of rainwater with a high flow velocity will overflow from the lower gutter 92.

[0068] Therefore, in this embodiment, one of the multiple downpipes 93, downpipe 93A, is positioned to pass between the first stop 5 and the second stop 6, and penetrates the connecting member 80 vertically. As a result, downpipe 93A drains rainwater from the upper gutter 91 without allowing rainwater to flow into the lower gutter 92. Downpipe 93A does not directly drain rainwater from the lower gutter 92. Downpipe 93A is the downpipe 93A located in the center of the multiple downpipes 93 arranged in the first horizontal direction. Furthermore, it is sufficient that the lower end of the downpipe 93A is located inside the through member 95, and the downpipe 93A does not necessarily have to penetrate the connecting member 80. In this case, for example, the lower end of the downpipe 93A may be located above the upper surface of the connecting member 80, and the lower end of the through member 95 and the downpipe 93B (the portion of the downpipe 93 that extends downward from the through member 95) are connected directly or via an enlarged diameter joint (not shown). In this case, the downpipe 93B is formed from a different pipe material than the downpipe 93A. Furthermore, the downpipe 93B (the portion of the downpipe 93 that extends downward from the through member 95) may be equipped with a junction joint that includes a branching section such as a tee (not shown), and rainwater from the lower eaves gutter 92 may flow into the downpipe 93B via the branching section of this junction joint.

[0069] As shown in Figures 13 to 15, the through member 95 is fixed to the connecting member 80. The through member 95 is positioned in the through hole 51e. The through hole 51e is formed in the connecting body 51. The opening area of ​​the through hole 51e is, for example, 5 cm². 2 ~300cm 2 Preferably 13 cm 2 ~190cm 2 , more preferably 20cm 2 ~140cm 2 That is the case.

[0070] The through member 95 comprises a first member 61 and a second member 62. The first member 61 is positioned above the transponder body 51. The first member 61 may or may not be fixed to the transponder body 51. The second member 62 is positioned below the transponder body 51. The second member 62 is fixed to at least one of the first member 61 and the transponder body 51.

[0071] At least one of the first member 61 and the second member 62 is an injection-molded product. In this embodiment, both the first member 61 and the second member 62 are injection-molded products. The first member 61 and the second member 62 are injection-molded products of synthetic resins such as rigid polyvinyl chloride resin, polycarbonate, ABS, and AES. Note that the second member 62 and the first member 61 are not limited to synthetic resin materials and may be formed from cast iron materials using a mold. Furthermore, the first member 61 and the second member 62 may be formed from different materials.

[0072] As shown in Figures 14 and 15, the first member 61 includes a first pipe 63 and a first flange 64. The first pipe 63 and the first flange 64 are arranged coaxially. The first pipe 63 is a circular pipe into which the downpipe 93A is inserted. The first pipe 63 is positioned in the through hole 51e. In the illustrated example, the first pipe 63 has the same diameter along its entire vertical length. The outer diameter of the first pipe 63 is equal to or slightly smaller (for example, about 5% smaller than the inner diameter) of the through hole 51e.

[0073] The first flange 64 extends radially outward from the first pipe 63. The first flange 64 is positioned on the upper surface of the transponder body 51. The first flange 64 is positioned vertically in the center of the first pipe 63. The first flange 64 is a flat annular (circular) shape extending perpendicular to the pipe axis of the first pipe 63. The first flange 64 extends continuously around the entire circumference. The lower surface of the first flange 64 may be fixed (e.g., glued) to the upper surface of the transponder body 51. Furthermore, a male thread may be formed on the portion of the first pipe 63 that is located below the first flange 64 (hereinafter also referred to as the lower end).

[0074] The second member 62 includes a second pipe 65 and a second flange 66. The second pipe 65 and the second flange 66 are arranged coaxially. The second pipe 65 is a circular pipe. The second pipe 65 is located below the through hole 51e. The second pipe 65 is located at the lower end of the first pipe 63. The second pipe 65 has a larger diameter than the first pipe 63. The second pipe 65 covers the first pipe 63 from the radial outside. The lower end of the first pipe 63 is located inside the second pipe 65. In the illustrated example, the lower end of the second pipe 65 is located below the lower end of the first pipe 63. The lower end of the second pipe 65 may be located above the lower end of the first pipe 63, or it may be at the same height as the lower end of the first pipe 63.

[0075] The inner surface of the second pipe 65 may have a female thread that fits into the male thread. The second pipe 65 may be screwed (screw-fitted) to the lower end of the first pipe 63. The second pipe 65 may or may not be bonded to the first pipe 63.

[0076] The second flange 66 extends radially outward from the second pipe 65. The second flange 66 is positioned on the lower surface of the connecting body 51. The second flange 66 is positioned at the upper end of the second pipe 65. The second flange 66 is a flat annular (circular) shape extending in a direction perpendicular to the pipe axis of the second pipe 65. The second flange 66 extends continuously around the entire circumference. The upper surface of the second flange 66 may or may not be fixed (e.g., glued) to the lower surface of the connecting body 51. The outer diameter of the second flange 66 may be the same as, larger than, or smaller than the outer diameter of the first flange 64. The connecting body 51 is sandwiched between the second flange 66 and the first flange 64.

[0077] Since the downpipe 93A is positioned inside the first pipe 63 or the second pipe 65, the connecting member 80 fixed to the through member 95 is less likely to shift. Furthermore, if the through member 95 and the downpipe 93A are fixed together with adhesive or the like, the connecting member 80 can be made even less likely to shift. In this case, there is no need to fix the connecting member to the end caps 5 and 6, so it is not necessary to provide the canopy portion 38 or the like on the end caps 5 and 6. The end caps 5 and 6 may be an integral part of the eaves gutters 2 and 3 rather than separate components. For example, the end caps 5 and 6 may be formed by folding in the ends of the eaves gutters 2 and 3.

[0078] It should be noted that the technical scope of the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the invention.

[0079] The front notch 45 and the rear notch 46 may be omitted. In particular, if the canopy portions 38 and 106 protrude from the upper part 30a and 105a of the main body to the opposite side of the gutter, it is preferable not to provide notches. Pre-drilled holes for inserting screws 58 may be formed in the connecting members 8 and 103 and the canopy sections 38 and 106. Conversely, pre-drilled holes may not be present in the canopy sections 38 and 106. In this case, when fixing the connecting members 8 and 103 to the canopy sections 38 and 106, the screws 58 may penetrate through the parts of the connecting members 8 and 103 and the canopy sections 38 and 106 that do not have pre-drilled holes. There are not limited to just two screws (screw 58). There can be one screw (screw 58), or three or more. You may use adhesive instead of screw 58. The connecting members 8 and 103 may be fixed to both of the two stoppers 5 and 102.

[0080] Furthermore, without departing from the spirit of the present invention, the components in the above embodiments may be replaced with well-known components as appropriate, and the above-described modifications may be combined as appropriate. [Explanation of Symbols]
