JP-A-6-269710

  The present invention has been invented in view of the above-described conventional problems, and can be applied to a location where a large amount of rainwater is prevented while preventing scattering, and an unprecedented flow of rainwater can be appreciated. It is an object of the present invention to provide a flowing water appreciation rain gutter device that has an excellent soiling effect and does not deteriorate the viewing effect over a long period of time.

  In order to solve the above-mentioned problem, a flowing water appreciation rain gutter apparatus 6 according to the present invention collects drainage water by collecting a water collecting device 2 that collects rain water from the eaves wall 1, a vertical gutter composed of a cylindrical body 3, and a sewage at a lower side. A rainwater appreciation rain gutter device 6 comprising a drainage device 5 to be discharged to a pipe 4, characterized in that the rainwater collected by the water collection device 2 flows down mainly along the outer peripheral surface of the tubular body 3. It is.

  With such a configuration, the rainwater of the eaves 1 can be collected by the water collecting device 2, and the rainwater collected by the water collecting device 2 can flow down mainly along the outer peripheral surface of the tubular body 3. Rainwater flowing down along the outer peripheral surface of the body 3 can be appreciated. Moreover, the outer peripheral surface of the cylindrical body 3 flows smoothly and does not scatter. Further, when the rainwater flows along the outer peripheral surface of the cylindrical body 3, the ripples drawn by the rainwater can be appreciated. Further, since rainwater flowing through the cylindrical body 3 is collected and discharged to the drain pipe 4, a large amount of rainwater can be drained.

  Moreover, it is preferable to pass the dust inflow prevention device 7 when the rainwater of the eaves wall 1 flows through the water collecting device 2.

  By adopting such a configuration, rainwater from which dust has been removed by the dust inflow prevention device 7 flows down along the outer peripheral surface of the cylindrical body 3, and the water collecting device 2 is prevented from being clogged and smooth. The rain water can flow down along the outer peripheral surface of the cylindrical body 3.

  Moreover, it is preferable that the outer surface of the cylindrical body 3 is subjected to a hydrophilic treatment.

  By setting it as such a structure, when rainwater flows down along the outer peripheral surface of the cylindrical body 3, rainwater flows smoothly on an outer peripheral surface, and it can prevent further scattering.

  Further, the lower end portion of the cylindrical body 3 is detachably fitted into a lower fitting portion 38 provided in the drainage device 5, and the upper end portion of the cylindrical body 3 is detachable into an upper fitting portion 60 provided in the water collecting device 2. The dimension M from the upper end of the cylindrical body 3 to the upper end of the upper fitting part 60 in a state where the lowermost end of the cylindrical body 3 is located at the lower end of the lower fitting part 38 is from the lower end to the upper end of the lower fitting part 38. It is preferably longer than the dimension N.

  With this configuration, after the cylindrical body 3 is lifted upward and the lower end of the cylindrical body 3 is shifted above the upper end of the lower fitting portion 38, the upper end portion of the cylindrical body 3 is moved to the upper fitting portion 60. The cylindrical body 3 can be easily removed and the cylindrical body 3 can be easily attached in the reverse order to the above. Thereby, the cylindrical body 3 can be removed and cleaned, or the cylindrical body 3 can be removed during a typhoon or the like so as not to be damaged.

  Moreover, the upper fitting part 60 for fitting the upper end part of the cylindrical body 3 to the water collecting apparatus 2 is provided, and the rain water of the eaves 1 is fitted into the cylindrical body 3 fitted into the upper fitting part 60 in the upper fitting part 60. It is preferable to provide an inner water passage opening 61 for flowing water and to form an outer water passage 62 for flowing rain water of the eaves 1 to the outer surface side of the tubular body 3 outside the upper fitting portion 60.

  With such a configuration, rainwater flowing through the eaves bowl 1 can flow along the outer peripheral surface of the cylindrical body 3 and can flow inside the cylindrical body 3. Even if the amount of rainwater increases, it can be drained reliably, and even if the amount of rainwater flowing through the eaves 1 increases, the amount of rainwater flowing along the outer peripheral surface of the tubular body 3 does not increase too much, Rainwater flowing down along the outer peripheral surface of the cylindrical body 3 without flowing too much rain water flowing along the outer peripheral surface of the cylindrical body 3 or scattering too much or flowing smoothly. The ornamental effect can be prevented from decreasing.

  Moreover, it is preferable that the lower end part of the opening 61 for inner side water flow is substantially the same height as the bottom face part of the eaves 1.

  With such a configuration, when the amount of rainwater flowing through the eaves 1 is slight and the momentum is weak, it flows from the outer water passage 62 to the outer peripheral surface of the cylindrical body 3, and the amount of rainwater flowing through the eaves 1 is large. As the momentum increases, not only does it flow from the outer water passage 62 to the outer peripheral surface of the tubular body 3, but also flows into the interior from the upper end opening of the tubular body 3. As a result, when the amount of rainwater flowing through the eaves 1 increases and the momentum increases, more rainwater flows into the upper end opening of the cylindrical body 3 and the amount of rainwater flowing through the eaves 1 is reduced. Even if it changes, rainwater can be made to flow on the outer peripheral surface of the cylindrical body 3 in substantially the same manner, and the appreciating effect of rainwater flowing down along the outer peripheral surface of the cylindrical body 3 can be prevented from decreasing due to the amount of rain. .

  Further, a plurality of vertical plate-like inward projections 37 project inward from the inner periphery of the drainage cylinder portion 35 constituting the main body of the water collecting device 2, and the projecting tips of the inward projections 37 The enclosed portion becomes a lower fitting portion 38 for fitting the lower end portion of the cylindrical body 3, and the tips of the plurality of inward protruding portions abut against the outer peripheral surface of the cylindrical body 3, and the adjacent inward protruding It is preferable that the interval between the portions 37 becomes wider toward the inner peripheral side of the drainage cylinder portion 35.

  With such a configuration, rainwater flowing along the outer peripheral surface of the cylindrical body 3 is transmitted to both side surfaces of the plurality of inwardly projecting protrusions 37 in the lower fitting portion 38 of the cylindrical body 3. And flow down along both sides. In this case, since the interval between the adjacent inward projections 37 becomes wider toward the inner peripheral side of the drainage cylinder part 35, the inner side of the drainage cylinder part 35 extends along the side surface of the adjacent inward projection 37. Rainwater that flows down while flowing toward the circumferential side does not collide with each other and is not disturbed, and can smoothly drain downward along the inward projection 37.

  Further, a plurality of vertical plate-like inward projections 37 project inward from the inner periphery of the drainage cylinder portion 35 constituting the main body of the water collecting device 2, and the projecting tips of the inward projections 37 The enclosed portion becomes a lower fitting portion 38 for fitting the lower end portion of the cylindrical body 3, and each tip of the plurality of inward protruding portions 37 abuts on the outer peripheral surface of the cylindrical body 3, and the inward protruding portion It is preferable that the cross-sectional shape of the upper end surface of 37 is a mountain shape or an upward arc shape in which the central portion is convex, and the upper end surface of the inward projecting portion 37 is positioned below the upper end of the drainage cylinder portion 35.

  When rainwater flowing along the outer peripheral surface of the cylindrical body 3 is transmitted to the upper end surfaces of the plurality of inwardly protruding portions 37 in the form of vertical plates at the lower fitting portion 38 of the cylindrical body 3, the upper end surface of the inwardly protruding portion 37 Since the cross-sectional shape is a mountain shape or an upward arc shape with a convex central portion, the upper end surface does not run to the inner peripheral surface side of the drainage cylinder portion 35 and flows inward while flowing along the upper end surface. It will flow down to the side of the protrusion 37. Further, since the upper end surface of the inward projecting portion 37 is located below the upper end of the drainage cylinder portion 35, it flows through the upper end surface of the inward projection portion 37 and scatters outward beyond the drainage cylinder portion 35. There is nothing.

  In addition, a plurality of dust removal protrusions 32 are provided on the upper surface of the dust inflow prevention cover 30, and a water passage opening 31 is provided between the dust removal protrusions 32. It is preferable that the cross-sectional shape of the end face is a mountain shape or an upward arc shape having a convex central portion.

  When the top surface of the dust inflow prevention cover 30 has a planar shape, when rainwater flowing down from the eaves of the roof flows into the top surface of the dust inflow prevention cover 30, it collides with the top surface and scatters vigorously. Although there is a risk of splashing outside, a plurality of dust-proof projections 32 are provided on the upper surface of the dust inflow prevention cover 30, so that the rainwater flowing down from the eaves is prevented from splashing vigorously. In addition, rainwater can be made to flow smoothly to the side of the water passage opening 31 between the dust removal projections 32 along the mountain-shaped or upward arc-shaped portion having a convex central portion.

  Moreover, it is preferable to carry out a hydrophilic treatment with a photocatalyst.

  With such a configuration, when rainwater flows down along the outer peripheral surface of the cylindrical body 3 due to the superhydrophilicity of the photocatalyst, the rainwater smoothly forms a ripple along the outer peripheral surface while preventing scattering. When flowing, improving the viewing effect of the flow of rainwater, and when the rainwater flows while forming ripples along the outer peripheral surface, it is adhering to the cylindrical body by the photocatalyst at the same time The dirt can be raised and shed. Here, if dirt is attached to the cylindrical body 3, the smooth flow of rainwater along the outer surface of the cylindrical body 3 is hindered, ripples are not formed, and the appreciation effect of the rainwater flow is reduced. However, in the present invention, since the dirt is raised and washed away, the effect of appreciating the flow of rainwater does not deteriorate over a long period of time.

  Moreover, it is preferable that the vertical or horizontal streak-like ridges 42 or streak ridges are formed on the outer surface of the cylindrical body 3.

  With such a configuration, when rainwater flows down along the outer surface of the cylindrical body 3, the rainwater flows along the streak-like concave stripes 42 or the streak-like ridges, and is more excellent in viewing effect than changes. The flow of rainwater can be revealed, and the scattering can be further prevented.

  As described above, the present invention is a flowing water appreciation rain comprising a water collecting device that collects rainwater from eaves, a vertical gutter made of a cylindrical body, and a drainage device that collects flowing water and discharges it to a drain pipe below. Since it is a dredging device that causes rainwater collected by the water collecting device to flow down mainly along the outer peripheral surface of the cylindrical body, it can be applied to locations where it prevents splashing and allows a large amount of rainwater to flow. It is possible to provide a rainwater appreciation rainwater device with high commercial value that can appreciate the state of rainwater flowing down along the outer peripheral surface of the cylindrical body, in particular, the ripples drawn by rainwater.

  Hereinafter, the present invention will be described based on embodiments shown in the accompanying drawings.

  As shown in the exploded perspective view of FIG. 6, the flowing water appreciating rain gutter device 6 of the present invention has a water collecting device 2 that collects rain water from the eaves 1, a vertical gutter made of a cylindrical body 3, and downflow water below. A drainage device 5 to be collected and discharged to the drainage pipe 4 and a dust inflow prevention device 7 are configured.

  FIG. 7 shows a water collecting apparatus. 9 to 13 show components constituting the water collecting device 2. The water collecting device 2 is connected to the main body 9 attached to the drainage port 8 of the eaves 1 and the main body 9. A detachable lower part 10 that is detachably attached is provided.

  The main body 9 is composed of a main body upper portion 9a and a main body lower portion 9b.

  As shown in FIGS. 9 and 10, the main body upper portion 9 a is provided with a flange portion 13 outwardly from the upper end opening of the cylindrical portion 12 having the male threaded portion 11 on the outer peripheral portion, and is formed from the inner peripheral surface of the cylindrical portion 12. The upper end portions of the plurality of vertical plate-like projecting piece portions 14 projecting in the upward direction are projected upward from the cylindrical portion 12. Further, a drain passage portion 16 is formed between the adjacent projecting piece portions 14.

  When the upper ends of the cylindrical body 3 that is a vertical rod are fitted into the vertical rod support portion 15 in the cylindrical portion 12, the distal ends of the plurality of protruding piece portions 14 are cylindrical bodies. 3, the cylindrical body 3 is supported by contact with the outer surface, and in this embodiment, the vertical rod support portion 15 is configured by the tip portions of the plurality of projecting piece portions 14. A portion surrounded by the portion 15 is an upper fitting portion 60 for fitting the upper end portion of the vertical rod made of the cylindrical body 3.

  The upper end portions of the plurality of projecting piece portions 14 are integrally connected to the central cylindrical portion 17 serving as an overflow portion, and the central cylindrical portion 17 is a portion surrounded by the vertical rod support portion 15 as described above. When the upper end portion of the cylindrical body 3 is fitted and supported in the fitting portion 60, the upper end of the cylindrical body 3 is opposed to the upper end portion, and the upper diameter of the central cylindrical portion 17 is larger than the lower portion. Yes.

  Here, when the upper fitting portion 60, which is a portion surrounded by the respective vertical rod support portions 15, is inserted into the upper fitting portion 60 with the upper end portion of the vertical rod made of the cylindrical body 3, rainwater is tubular. 3 is provided with an inner water passage opening 61 for flowing into the upper end opening 3.

  In the embodiment shown in the accompanying drawings, the upper portion of the drainage passage portion 16 is a common passage portion 63 and the lower portion is an outer water passage 62, and the inner end portion of the common passage portion 63 (at the tip of the projecting piece portion 14). The opening between the vertical rod support portions 15) is an inner water passage opening 61 in the upper fitting portion 60.

  Moreover, in embodiment shown to an accompanying drawing, the opening of the center cylinder part 17 is also the opening 61 for internal water flow, and there is much rainfall of the rainwater which flows through the eaves wall 1, and the water level became higher than the center cylinder part 17. In such a case, an overflow from the opening of the central cylindrical portion 17 flows into the cylindrical body 3.

  As shown in FIG. 11, the main body lower portion 9 b has an upper end portion of the outer cylindrical portion 18 and an upper end portion of the inner cylindrical portion 19 that are integrally connected and a flange portion 20 that extends outward from the outer periphery of the upper end of the outer cylindrical portion 18. And a female threaded portion 21 is provided on the inner peripheral surface of the inner cylindrical portion 19, and a fitting recess 22 is formed between the lower portion of the inner cylindrical portion 19 and the outer cylindrical portion 18.

  As shown in FIGS. 12 and 13, the detachable lower portion 10 is provided with a water collection guide portion 25 at the lower end portion of the upper cylinder portion 24 having an internal thread portion 23 on the inner periphery, and further, water collection from the lower end portion of the upper cylinder portion 24. The cover cylinder part 24a protrudes downward so as to cover the outside of the guide part 25.

  As shown in FIG. 12, the water collection guide portion 25 includes an inverted truncated conical cylindrical portion 29 and an inverted truncated conical shape having an inverted truncated cone shape that is inclined so that the front end side is directed downward from the lower end of the upper tubular portion 24. A number of comb portions 26 are formed so as to protrude from the peripheral portion of the lower end edge portion of the cylindrical portion 29 so that the tip end side is downward, and slits 28 are opened between the comb portions 26 in the vertical direction and the tip end side. In addition, a portion surrounded by the tips of the many comb portions 26 is a vertical hook insertion portion 27 into which the cylindrical body 3 having a vertical hook is inserted.

  The slit width of the slit 28 between the comb portions 26 is 1.5 to 3 mm.

  In addition, as shown in FIG. 12, many comb portions 26 have different inward projecting lengths in plan view. In the embodiment of FIG. 12, the comb portions 26a have long projecting lengths. Comb portions 26b having a short protruding length are alternately provided in the circumferential direction. The comb portion 26a having a long protruding length is configured such that the tip of the comb portion 26a having a long protruding length comes into contact with the outer surface of the cylindrical body 3 in a state where the cylindrical body 3 is inserted into the vertical hook fitting insertion portion 27. Or it is set so that a gap of 1 mm or less may be generated between the two, and the comb part 26b having a short projecting length is a projecting length in a state in which the cylindrical body 3 is inserted into the vertical hook fitting insertion part 27. It is set so that a gap of 1.5 to 3 mm is generated between the tip of the short comb portion 26 b and the outer surface of the cylindrical body 3.

  The lower end of the cover cylinder part 24 a is the same height as the lower end of the comb part 26 or lower than the lower end of the comb part 26.

  Here, the slit width of the slit 28 between the comb portions 26 is 1.5 to 3 mm, and a gap of 1.5 to 3 mm is provided between the tip of the comb portion 26 b having a short protruding length and the outer surface of the cylindrical body 3. The reason why the water is set to occur is to allow rainwater to flow almost uniformly on the outer peripheral surface of the cylindrical body 3 through the slit 28 and the gap.

  When the width of the slit 28 and the gap exceeds 3 mm, rainwater flowing through the slit 28 does not flow along the slit 28 toward the cylindrical body 3 side, but directly falls from the top of the slit 28 through the slit 28 and is scattered. Alternatively, it is because a part of the outer peripheral surface of the cylindrical body 3 is concentrated in the circumferential direction so that the rainwater flows down and the rainwater cannot flow down almost uniformly in the circumferential direction. Further, if the width of the slit 28 and the gap is less than 1.5 mm, the slit 28 and the gap are easily clogged, and rainwater cannot be smoothly flowed to the outer peripheral surface of the cylindrical body 3, so that the width of the slit 28 and the gap is 1 It is necessary to secure 5 mm or more.

  The water collecting device 2 having the above configuration is attached to the drainage port 8 of the eaves 1.

  That is, the cylinder part 12 of the main body upper part 9a is inserted into the drainage port 8 from above, and the cylinder part 12 protrudes below the eaves bowl 1 and the flange part 13 is brought into contact with the upper surface of the bottom part of the eaves bowl 1. In this state, the female screw portion 21 of the inner cylindrical portion 19 of the main body lower portion 9 b is screwed into the male screw portion 11 of the cylindrical portion 12, and the flange portion 20 is pressed against the bottom lower surface of the eave rod 1. Clamp the bottom of the heel 1 from above and below. In this state, the female screw portion 21 is screwed onto the upper portion of the male screw portion 11. In this way, the main body portion 9 composed of the main body upper portion 9a and the main body lower portion 9b is attached to the drain outlet 8 portion of the eaves bowl 1.

  Next, the internal thread portion 23 of the upper cylindrical portion 24 of the detachable lower portion 10 is detachably screwed into the lower portion of the external thread portion 11 of the main body upper portion 9a, and the upper end portion of the upper cylindrical portion 24 of the detachable lower portion 10 is fitted into the lower body portion 9b. By fitting into the recess 22, the detachable lower part 10 is detachably attached to the main body 9.

  As described above, the water collecting device 2 is attached to the drainage port 8 of the eaves bowl 1. The drainage port 8 of the eaves bowl 1 further includes a dust inflow prevention cover 30 constituting the dust inflow prevention device 7 in the eaves bowl 1. It comes to be covered with.

  The dust inflow prevention cover 30 is as shown in FIG. 15. The lower surface has an opening, and a large number of water passage openings 31 are provided on the side peripheral surface and the upper surface. Further, the lower surface of the upper surface portion is directed downward from the center. A locking leg 33 having elasticity is provided in a protruding manner.

  The dust inflow prevention cover 30 is disposed inside the eaves 1 so as to cover the drainage port 8 to which the water collecting device 2 is attached, and the locking leg 33 is inserted into the central cylindrical portion 17 to be locked. The locking portion 34 at the lower end of the leg 33 is attached by being detachably locked to the lower end opening edge of the central cylindrical portion 17.

  The water passage opening 31 provided in the dust inflow prevention cover 30 has an opening width of 1.5 mm to 3 mm.

  That is, the dust inflow prevention cover that conventionally covers the drainage port 8 of the eaves 1 has a large opening width of about 5 to 15 mm for the water passage opening and can avoid falling leaves, but the width or diameter is 5 Dust and the like of ˜15 mm or less are allowed to flow as they are.

  However, in the flowing water appreciation rain gutter apparatus 6 that allows the appearance of the rain water flowing down along the outer peripheral surface of the cylindrical body 3 as in the present invention, the rain water collected by the water collecting apparatus 2 is used. It is necessary to flow almost uniformly in the circumferential direction of the outer peripheral surface of the cylindrical body 3, and therefore, in the present invention, as described above, the slit width of the slit 28 between the comb portions 26 is set to 1.5 to 3 mm to protrude. Since a gap of 1.5 to 3 mm is set between the tip of the comb part 26b having a short length and the outer surface of the cylindrical body 3, the dust inflow prevention cover 30 is passed through the gap correspondingly. The opening width of the water opening 31 is set to 1.5 mm to 3 mm, and dust (for example, fallen leaves, etc.) that closes the slits 28 and gaps for allowing rainwater to flow almost uniformly on the outer peripheral surface of the cylindrical body 3. Make sure that insects, dust, etc.) do not flow into the water collecting device 2. The clogging of the door 28 and the gap is adapted to suppress. Further, the opening width of the water passage opening 31 of the dust inflow prevention cover 30, the slit width of the slit 28 between the comb portions 26, the tip of the comb portion 26 b having a short protruding length, and the outer surface of the cylindrical body 3. If the width of the gap between them is the same size, the small dust that has passed through the water passage opening 31 of the dust inflow prevention cover 30 is slit 28, the tip of the comb portion 26b having a short protruding length, and the cylindrical body. 3 flows through the gap between the outer surface and the slit 28 and the gap, and the dust is not further clogged.

  A plurality of dust removal projections 32 project outward from the water passage opening 31 on the side circumferential surface and the upper surface of the dust inflow prevention cover 30. As shown in FIG. 15 (a), a plurality of dust-proof projections 32 protrude from both side surfaces intersecting the longitudinal direction of the eaves 1 among the side peripheral surface portions of the dust inflow prevention cover 30, as shown in FIG. An imaginary line connecting a plurality of dust-proofing protrusions 32 protruding in the shape of an arc is formed. In addition, the interval between the adjacent dust removal projections 32 is set wider than the opening width of the water passage opening 31, and the protruding tip of the dust removal projection 32 is chamfered.

  Thereby, for example, fallen leaves are prevented from flowing into the water collecting device 2 by the dust-rejecting protrusions 32, but the imaginary line connecting the plurality of dust-removing protrusions 32 protruding on both side surfaces is arcuate. The fallen leaves do not stick to the tip surface of the dust removal projection 32, and even if the rainwater is caught by fallen leaves, the water passage opening is provided from a part other than the part that is caught. It flows into the space between the dust removal protrusions 32 wider than the opening width of 31, and can smoothly flow into the water collecting apparatus 2 through the water passage opening 31 having a narrow opening width.

  Further, if the upper surface portion of the dust inflow prevention cover 30 has a planar shape, when rainwater flowing down from the eaves edge of the roof flows into the upper surface portion of the dust inflow prevention cover 30, it collides with the upper surface portion and scatters vigorously. There is a risk of splashing out of the cage 1. However, as described above, since a plurality of dust removal protrusions 32 are provided on the upper surface of the dust inflow prevention cover 30, the rainwater flowing down from the eaves can be prevented from being scattered violently. . Here, the dust removal projection 32 has an upward arc shape in which the cross-sectional shape of the upper end surface is a mountain shape or the center portion is convex, and the dust removal projection 32 has a mountain shape or an arc shape as rainwater flowing down to the upper end surface. It will flow smoothly to the opening 31 for water flow between the protrusions 32 for dust removal along the inclined surface which became, and it can prevent scattering of rain water.

  The dust inflow prevention cover 30 is easily removed by releasing the engagement between the engagement portion 34 at the lower end of the engagement leg 33 and the lower end opening edge of the central cylinder portion 17, so that the dust inflow prevention cover 30 can be easily formed. The trapped dust can be removed. Here, although the locking part 34 has an arrowhead shape, the tip part of the arrowhead has no return part, making it easy to attach and detach.

  In addition, since the dust inflow prevention cover 30 is detachable as described above, the shape of the central cylindrical portion 17 in the water collecting device 2 is made common so that it can be detachably attached to water collecting devices having different drainage capacities. be able to.

  It is preferable to use the vertical hook made of the cylindrical body 3 whose outer surface is treated.

  The cylindrical body 3 is inserted into a vertical hook insertion portion 27 that is a portion surrounded by the tips of a number of comb portions 26 of the water collecting device 2, and further fitted into the vertical hook support portion 15, and the uppermost end is It is inserted in the fitting recess 22.

  Further, the drainage device 5 is as shown in FIG. 14, and the drainage cylinder part 35 constituting the main body is provided with a hole having a diameter larger than that of the cylindrical body 3, and the upper end part of this hole is the other part of the hole. A large-diameter hole portion 36 having a diameter larger than that of the portion, and a plurality of vertical plate-shaped inward from the inner periphery of the portion of the drainage cylinder portion 35 excluding the large-diameter hole portion 36 toward the inside. A projecting portion 37 is projected. The plurality of inward projections 37 project at a constant pitch in the circumferential direction of the hole, and a gap 49 for drainage is formed between the inward projections 37.

  The plurality of inward projections 37 have a radial shape (radial centered on the central portion of the drainage cylinder portion 35), and the interval between the adjacent inward projections 37 increases toward the inner peripheral side of the drainage cylinder portion 35. It is wide.

  In addition, the cross-sectional shape of the upper end surface of the inward projection 37 is a mountain shape or an upward arc shape with a convex central portion, and the upper end surface of the inward projection 37 is lower than the upper end of the drainage cylinder portion 35. Is located.

  The upper half of the plurality of inward projections 37 has a shorter projection length than the lower half, and the top ends of the upper half of the plurality of inward projections 37 are formed at the ends of the cylindrical body 3. A portion that is located on a virtual circle having the same diameter as the outer diameter and that is surrounded by the top ends of the upper and lower halves of the plurality of inward projections 37 is for fitting the lower end of the cylindrical body 3 A lower fitting portion 38 is formed. Further, the lower end of the upper half tip of the inward projection 37 and the upper end of the lower half tip are continuous at the step 39.

  The drain cylinder 35 is formed with a lower fitting recess 40 that opens downward.

  The lower fitting portion 38 of the drainage device 5 is supported so that the lower end portion of the cylindrical body 3 can be pulled out freely. In this case, the lower end surface of the cylindrical body 3 is placed on the step portion 39. Therefore, rainwater that flows along the outer peripheral surface of the cylindrical body 3 is drained through the drainage gap 49 between the inward projecting portions 37 that project from the inner peripheral portion of the hole of the drainage cylindrical portion 35. .

  In the embodiment shown in the accompanying drawings, the upper end portion of the adjustment member 41 made of a cylinder is fitted into the lower fitting recess 40 of the drainage cylinder portion 35, and the upper end of the drainage pipe 4 is fitted into the lower end portion of the adjustment member 41. It is like that.

  As shown in FIGS. 1, 3, and 6, the adjustment member 41 is composed of an upper eccentric member 50 and a lower eccentric member 51, and the upper eccentric member 50 corresponds to the drain tube portion 35. A connecting tube portion 53 that is eccentric with respect to the fitting tube portion 52 is formed integrally with a lower portion of the fitting tube portion 52 that is rotatably fitted in the lower fitting recess 40, and the lower eccentric member 51 is a connecting tube. A drain pipe connecting cylinder part 55 that is eccentric with respect to the connected cylinder part 54 is formed at the lower part of the connected cylinder part 54 that is rotatably fitted to the part 53, and the drain pipe connecting cylinder part 55. The upper end of the drain pipe 4 is fitted into the pipe.

  Then, the fitting cylinder part 52 of the upper eccentric member 50 is rotated with respect to the cylindrical body 3, the connected cylinder part 54 is rotated with respect to the connection cylinder part 53, and the drain pipe connection cylinder with respect to the drain pipe 4. By rotating the portion 55, the tubular body 3, which is a vertical rod with the upper end connected to the water collecting device 2, and the drainage pipe 4 can be connected even when they are misaligned in a plan view. .

  Of course, the upper end portion of the drain pipe 4 may be directly fitted into the lower fitting recess 40 without using the adjusting member 41.

  Here, the lower end portion of the cylindrical body 3 is fitted into and supported by the lower fitting portion 38 provided in the drainage device 5, and the upper end portion of the cylindrical body 3 is fitted into the upper fitting portion 60 provided in the water collecting device 2. It will be further explained about supporting it.

  In the embodiment shown in FIG. 1, the lower end portion of the tubular body 3 is detachably fitted into the lower fitting portion 38 provided in the drainage device 5, and the upper fit portion in which the upper end portion of the tubular body 3 is provided in the water collecting device 2. The dimension M from the upper end of the cylindrical body 3 to the upper end of the upper fitting part 60 in a state where the lowermost end of the cylindrical body 3 is located at the lower end of the lower fitting part 38 when the part 60 is detachably fitted. The length of the cylindrical body 3 is set so as to be longer than the dimension N from the lower end to the upper end of the lower fitting portion 38.

  Thereby, after lifting the cylindrical body 3 upward and shifting the lower end of the cylindrical body 3 above the upper end of the lower fitting portion 38, the upper end portion of the cylindrical body 3 is extracted downward from the upper fitting portion 60. The tubular body 3 can be easily removed by a so-called “Kendon method” to clean and inspect the tubular body 3, and in the case of a typhoon or the like, the tubular body 3 can be easily removed to You can avoid being damaged by typhoons. When attaching the cylindrical body 3, it can be attached in the reverse order.

  Of course, in this invention, it is not limited only to this, The thing which prevented the cylindrical body 3 from being removable may be used.

  The flowing water appreciation rain gutter device 6 of the present invention configured by being connected in combination as described above is configured such that the rain water flowing through the eaves rod 1 passes through the water flow opening 31 of the dust inflow prevention cover 30 and the water collecting device 2. It flows into the common passage part 63 at the upper part of the drainage passage part 16. When the amount of rainwater flowing in from the eaves 1 is small, since the momentum of rainwater flowing into the common passage portion 63 is weak, rainwater does not reach the inner water passage opening 61, and almost the entire amount is above the drainage passage portion 16. From the common passage portion 63 to the lower outer water passage 62 as it is, and flows into the water collection guide portion 25. The rainwater that has flowed to the water collecting guide portion 25 flows while being partially rectified along the upper surface of the plurality of downwardly inclined comb portions 26 toward the outer peripheral surface side of the cylindrical body 3, and partly passes through the plurality of slits 28. It flows while being rectified toward the outer peripheral surface side of the cylindrical body 3, and substantially the entire circumference in the circumferential direction of the outer peripheral surface of the cylindrical body 3 from the gap between the tip of the comb portion 26 and the outer surface of the cylindrical body 3 and the front end of the slit 28. Rainwater flows almost uniformly over.

  Further, when the amount of rainwater flowing in from the eaves 1 increases, the momentum of rainwater flowing into the common passage portion 63 above the drainage passage portion 16 becomes stronger. 16 flows from the upper common passage portion 63 to the lower outer water passage 62 as it is, and flows to the outer peripheral surface side of the cylindrical body 3, but since the remainder is strong, it reaches the inner water passage opening 61 and reaches the inner water passage 61. The water flows into the upper end opening of the cylindrical body 3 from the water opening 61 and is drained.

  Therefore, even if the amount of rainwater flowing from the eaves 1 increases, a large amount of rainwater does not flow to the outer peripheral surface side of the cylindrical body 3, and a large amount of rainwater flows down the outer peripheral surface of the cylindrical body 3 and scatters around. Can be prevented. Moreover, when rainwater flows down along the outer peripheral surface of the cylindrical body 3, the amount of rainwater that flows down does not increase too much and does not flow smoothly, and rainwater flows down along the outer peripheral surface of the cylindrical body 3. The ornamental effect can be prevented from decreasing.

  The lower end portion of the inner water passage opening 61 is substantially the same height as the bottom surface portion of the eaves bowl 1 (the lower end portion of the inner water passage opening 61 is not only the same height as the bottom surface portion of the eave bowl 1 but is also shown in FIG. As in the embodiment, when the position of the upper end of the cylindrical body 3 when fitted into the upper fitting portion 60 is slightly lower than the bottom surface portion of the eaves rod 1 or the illustration is omitted, the upper fitting portion 60 is omitted. It is preferable that the position of the upper end of the cylindrical body 3 when it is fitted in is slightly higher than the bottom surface of the eaves 1. In this case, when the amount of rainwater flowing through the eaves 1 is small and the momentum is weak, the rainwater flows from the outer water passage 62 to the outer peripheral surface of the cylindrical body 3, and the amount of rainwater flowing through the eaves 1 increases and the momentum is strong. As it becomes, it flows not only from the outer water passage 62 to the outer peripheral surface of the cylindrical body 3 but also from the upper end opening of the cylindrical body 3 to the inside.

  As a result, when the amount of rainwater flowing through the eaves 1 increases and the momentum increases, more rainwater flows into the upper end opening of the cylindrical body 3 and the amount of rainwater flowing through the eaves 1 is reduced. Even if it changes, rainwater can be made to flow on the outer peripheral surface of the cylindrical body 3 in the same manner, and the effect of appreciating the rainwater flowing down along the outer peripheral surface of the cylindrical body 3 is not reduced by the amount of rain. it can.

  In this way, the rainwater that has flowed substantially uniformly over substantially the entire circumference of the outer peripheral surface of the upper end portion of the cylindrical body 3 is made to be a thin film over the entire circumference of the outer peripheral surface of the cylindrical body 3 without scattering. The rain water flows smoothly along the outer peripheral surface of the cylindrical body 3 and prevents the scattering that cannot be obtained by the conventional chain and the rain water flowing down the outer peripheral surface of the cylindrical body 3 in the form of a film. Appreciate the flow.

  In this case, it can be said that rainwater flows substantially uniformly over the entire gap in the circumferential direction of the outer peripheral surface of the cylindrical body 3 from the gap between the front end of the comb portion 26 and the outer surface of the cylindrical body 3 and the front end of the slit 28. The subtle changes in the rainwater flowing from the gaps and the tips of the slits 28 to the cylindrical body 3 cause a ripple in the rainwater film flowing on the outer peripheral surface of the cylindrical body 3 as shown in FIG. The appreciation effect of the rainwater flowing down with the outer peripheral surface flowing into a film can be improved.

  When a hydrophilic treatment is applied to the outer peripheral surface of the cylindrical body 3 by applying a hydrophilic treatment material on the outside of the cylindrical body 3 or by applying a coating material imparted with hydrophilicity, The scattering of rainwater flowing down along the outer peripheral surface can be further prevented and the water can flow smoothly along the outer peripheral surface.

  The cylindrical body 3 is formed of metal or synthetic resin. In the case of a metal, for example, an aluminum cylinder can be mentioned, but it is not necessarily limited to this.

  In any case, when a hydrophilic treatment is performed on the outer surface of the cylindrical body 3 made of metal or synthetic resin, ripples can be reliably formed when rainwater flows along the outer surface of the cylindrical body 3.

  For hydrophilic treatment of the outer peripheral surface of the cylindrical body 3, for example, a coating film containing a photocatalyst having a photocatalytic effect such as titanium oxide is formed on the outer surface of the cylindrical body 3.

  Since the photocatalyst has super hydrophilicity, when rainwater flows down along the outer peripheral surface of the cylindrical body 3, the rainwater flows down while forming a thin film along the outer peripheral surface while preventing splashing, and the ripples It flows smoothly while forming. Thereby, not only the effect of preventing scattering is improved, but also ripples can be reliably formed, so that the effect of appreciating the flow of rainwater is further improved. In addition, since the photocatalyst has an antifouling effect, rainwater flows while forming ripples along the outer peripheral surface as described above, and at the same time, the photocatalyst is attached to the cylindrical body 3 by the photocatalyst. The dirt can be raised and washed away with rainwater.

  Here, if dirt is attached to the cylindrical body 3, the smooth flow of rainwater by the hydrophilic treatment along the outer surface of the cylindrical body 3 is hindered, and it is difficult to form beautiful ripples. However, in the present invention, since the dirt is raised and washed away by the photocatalyst as described above, it is possible to flow rainwater over a long period of time while producing beautiful ripples due to the hydrophilic treatment. The effect of appreciating the flow of rainwater can be prevented from decreasing.

  Further, as shown in FIG. 17 (a), a plurality of longitudinally elongated streak ridges 42 or streak ridges are formed in the circumferential direction on the outer surface of the cylindrical body 3, or as shown in FIG. 17 (b). In addition, a plurality of the streak-like recesses 42 or streak ridges in the lateral direction (circumferential direction) of the cylindrical body 3 may be formed at regular intervals.

  By forming the streak-like recesses 42 or streak-like protrusions on the outer surface of the tubular body 3 in this way, when rainwater flows down along the outer surface of the tubular body 3, the rainwater flows into the streak-like recesses 42 or streaks. It can flow along the ridges and show a stream of rainwater that has a better appreciation effect than changes. In addition, when rainwater flows down the outer surface of the tubular body 3 as a thin film, a part of the thin film flows along the streak-like concave stripes 42 or the streak ridges, so that the thin film contacts the tubular body 3. As resistance increases, scattering can be further prevented, and the effect of appreciating the flow of rainwater is improved.

  Rainwater that flows down in the form of a film on the outer peripheral surface of the cylindrical body 3 flows to the drainage device 5 and is drained.

  The rainwater flowing down in the form of a film on the outer peripheral surface of the cylindrical body 3 is a plurality of radial radii from the outer peripheral surface of the cylindrical body 3 as indicated by arrows in FIG. Is transferred to both side surfaces of the inwardly protruding portion 37 in the form of a vertical plate and smoothly flows down in a film shape along both side surfaces to flow from the drain tube portion 35 to the drain pipe 4 (there is an adjustment member 41). In this case, it flows into the drain pipe 4 through the adjusting member 41) and is drained. Since the interval between the adjacent inward projections 37 becomes wider toward the inner peripheral side of the drainage cylinder part 35, the distance between the adjacent inward projections 37 is increased toward the inner periphery side of the drainage cylinder part 35. Rainwater flowing down while flowing is not disturbed and collided in the drainage gap 49 formed between the inward projections 37, preventing the rainwater from splashing in the drainage device 5 and watching the rainwater flowing down. The ornamental effect is not reduced.

  In addition, since the cross-sectional shape of the upper end surface of the inward projection 37 is a mountain shape or an upward arc shape with the central portion being convex, rainwater flows from the outer peripheral surface of the cylindrical body 3 to the upper end surface of the inward projection 37. When transmitted, the rainwater transmitted to the upper end surface of the inward projecting portion 37 as indicated by the arrow in FIG. 8 does not run on the inner peripheral surface side of the drainage cylinder portion 35 through the upper end surface and flows in the middle. Will flow to the side of the. Further, since the upper end surface of the inward projecting portion 37 is located below the upper end of the drainage cylinder portion 35, it flows through the upper end surface of the inward projection portion 37 and scatters outward beyond the drainage cylinder portion 35. There is nothing.

  Further, the rainwater that has not been transmitted to the longitudinal plate-shaped inward projecting portion 37 flows as it is in the form of a film on the outer peripheral surface of the lower end portion of the cylindrical body 3 and flows into the drain pipe 4.

  Furthermore, the rainwater flowing down the inside of the cylindrical body 3 flows down from the lower end opening of the cylindrical body 3 to the central portion of the lower half of the drainage cylinder portion 35 and flows into the drainage pipe 4 (if there is an adjustment member 41) It flows to the drain pipe 4 through the adjusting member 41) and is drained.

  The rainwater flowing down in the form of a film on the outer peripheral surface of the cylindrical body 3 flows into the drainage gap 49 of the drainage device 5 and flows into the drainage pipe 4 (if there is an adjustment member 41, the drainage pipe 4 is passed through the adjustment member 41). Drained).

  When the amount of rainwater flowing in the eaves 1 increases and the rainwater that has passed through the dust inflow prevention cover 30 exceeds the upper end of the central tube portion 17, part of the rainwater flows from the upper opening of the central tube portion 17. From the portion 17 directly into the upper opening of the cylindrical body 3, passes through the cylindrical body 3, and flows into the drain pipe 4 (if there is an adjustment member 41, it flows into the drain pipe 4 via the adjustment member 41), Drained. Of course, also in this case, it flows down along the outer peripheral surface of the cylindrical body 3 in the same manner as described above.

  In this way, rainwater flowing through the eaves bowl 1 is collected by the water collecting device 2 and is allowed to flow down along the outer peripheral surface of the cylindrical body 3 fitted and held at the upper end of the water collecting device 2 (flowing through the eaves bowl 1). When the amount of rainwater is large, a part of the rainwater flows down through the tubular body 3), and the rainwater flowing along the outer peripheral surface of the tubular body 3 passes through the drainage device 5 having a hole having a diameter larger than that of the tubular body 3. Therefore, the rainwater that flows down along the outer peripheral surface of the cylindrical body 3 is drained to the drainage pipe 4 without flowing down, and even if the amount of rainwater increases, the drainage is surely drained. Therefore, the flowing water appreciation rain gutter device 6 of the present invention can be used without any trouble even in a place where a large amount of rain water flows, as well as in the vicinity of a gate near the entrance of the site, the entrance porch, and the like.
