Description

  The present invention relates to a rain gutter provided on an outdoor structure such as a carport or a terrace, and an outdoor structure equipped with the gutter.

  Generally, rain gutters are provided on outdoor structures such as carports and terraces. Since rain gutters are installed outdoors, dust and the like may accumulate on the drainage part, resulting in clogging. And, for example, in Patent Document 1, a configuration is disclosed in which a spiral protrusion is provided on a joint of a water collector to which a vertical shaft is connected, thereby applying a rotational force to rainwater and suppressing clogging of a pipeline. ing.

JP 2013-36235 A

  However, when dust exceeding the capacity of the above configuration accumulates, for example, when a large amount of fallen leaves accumulates, the clogging of the pipeline cannot be prevented, and rainwater may overflow from the side wall. In this case, because the drainage is provided with a slight drain gradient toward the water collector, the rainwater overflowing from the waterside flows to the water collector along the side and bottom surfaces and is connected to this water collector. It will flow to the ground along the outer surface of the vertical downpipe. For this reason, it was not easy to recognize that rainwater overflowed from the side, that is, the clogged rain gutter.

  In addition, when there is a lot of rainwater overflowing from the side, it may flow down directly to the ground. In this case, the horizontal line is disposed substantially horizontally although the drainage gradient is provided, so that rainwater flows down from a distorted part or the like generated at an unspecified location due to aged deterioration of the horizontal line. For this reason, the location where rainwater flows down cannot be predicted, and the rainwater may flow down into a busy passage.

  Therefore, an object of the present invention is to provide a rain gutter and an outdoor structure that can easily recognize the clogging of the rain gutter and can suppress the rain water falling from an unspecified location.

  In order to solve the above-mentioned problem, the invention described in claim 1 exceeds the upper limit height when the side wall and the rainwater in the side wall exceed the upper limit height set lower than the upper end of the side wall. Drainage means for discharging the rainwater to the outside of the reeds, wherein the drainage means guides the rainwater in the reeds to the outside of the reeds, and the rainwater led to the first water flow part And a second water passage portion that drops the water from a position below the reed.

  The invention described in claim 2 is the invention described in claim 1, further comprising a cap member that closes at least one end portion of the recumbent rib, wherein the drainage means is provided in the cap member. It is characterized by.

  The invention described in claim 3 is the invention described in claim 1 or 2, wherein at least one of the first water flow portion and the second water flow portion is constituted by a pipe line. It is characterized by.

  In order to solve the above-mentioned problem, the invention described in claim 4 is arranged under a roof part, a rain gutter having a horizontal gutter receiving rain water flowing down from the roof part, and below the roof part and the side gutter. An outdoor structure comprising a ceiling portion, wherein the rain gutter is constituted by the rain gutter according to any one of claims 1 to 3, and the second water flow portion of the drainage means is The outdoor structure is configured to drop rainwater guided to the first water flow portion from a position below the ceiling portion.

  According to the invention described in claim 1, when the rain water in the side wall exceeds the upper limit height set lower than the upper end of the side wall, the rain water exceeding the upper limit height is brought out of the side wall by the drainage means. Discharged. And the rain water in a side wall is guide | induced outside a side wall by the 1st water flow part and 2nd water flow part of a drainage means, and is dropped from the position below a side wall. Since it did in this way, since rainwater reliably falls from a 2nd water flow part, without passing along the outer surface of a rain gutter, while being able to recognize clogging of a rain gutter easily, rain water from an unspecified location can be recognized. Drop can be suppressed.

  According to the second aspect of the present invention, the cap member for closing at least one end portion of the reed is further provided, and the drainage means is provided in the cap member. For example, in the case of a reed with a uniform cross-section formed by extrusion, a separate process is required to provide a drainage means in a part of the reed. The material may be molded by injection molding or the like, or the sheet metal material may be molded by pressing or the like. Therefore, since the cap member has a high degree of freedom with respect to the shape at the time of molding as compared with the reed, the drainage means can be easily provided.

  According to the invention described in claim 3, at least one of the first water flow portion and the second water flow portion of the drainage means is constituted by a pipe line. For this reason, for example, when rainwater is transmitted to the surface, there is a risk of rainwater separating from the surface and splashing over a wide area if there is momentum in the rainwater. Can be suppressed.

  According to the invention described in claim 4, the outdoor structure includes a roof part, a rain gutter having a reed that receives rain water flowing from the roof part, and a ceiling part disposed below the roof part and the reed. The rain gutter is composed of the gutter according to any one of claims 1 to 3, and the second water passage portion of the drainage means is configured to supply rain water led to the first water passage portion. It is comprised so that it may fall from the position below the said ceiling part. In an outdoor structure, in order to improve designability, a structure may be employed in which the roof portion and the side wall are covered with a ceiling portion so as not to be visually recognized from below. In such a configuration, it is conceivable that rainwater overflowing from the side wall leaks to the ceiling part and falls on the ground from an unspecified location along the ceiling part. Therefore, the second water passage portion of the drainage means is configured to drop the rain water guided to the first water passage portion from a position below the ceiling portion, so that the rain water has the outer surface of the rain gutter and the ceiling portion. Since it falls reliably from a 2nd water flow part, without being transmitted, while being able to recognize the clogging of a rain gutter easily, the leakage to a ceiling part of rain water and a fall can be suppressed from an unspecified part.

The cap member 34 has a first member 36 and a second member 37.

  The first member 36 has a main body portion 36a formed such that the upper part is formed in substantially the same shape as the cross-sectional shape of the horizontal bar 31 and the lower part extends below the bottom wall part 32 of the horizontal bar 31 and a ceiling part 40 described later. It is a plate-shaped member which has. The first member 36 is attached to the end portion of the recumbent pad 31 and closes the end portion of the recumbent paddle 31. A cutout 36 b is provided at the upper end of the main body 36 a of the first member 36. The notch 36 b is formed such that the inner edge 36 c is lower in height than the upper end of the lower side wall 33 of the pair of side walls 33 of the horizontal bar 31. Thereby, when rainwater accumulates in the side wall 31, the rainwater flows out of the side wall 31 beyond the notch 36 b before exceeding the upper end of the side wall portion 33 of the side wall 31. The height of the inner edge portion 36c of the notch 36b is the upper limit height in the rainwater in the reed 31.

  The second member 37 is a plate-like member having a main body portion 37a formed in substantially the same shape as the first member 36 in plan view, and a flange portion 37b extending from the upper end portion of the main body portion 37a toward the inner side of the horizontal rod 31.

Further, an opening 40a through which the cap member 34 is inserted is formed in the ceiling portion 40.

  Next, the operation of this embodiment will be described with reference to FIG. When the water collector of the rain gutter 30 is clogged due to accumulation of dust or the like, rain water accumulates in the horizontal gutter 31. When the height of the rainwater accumulated in the side wall 31 exceeds a predetermined upper limit height (that is, the height of the inner edge portion 36c of the notch 36b), the rainwater exceeds the notch 36b of the cap member 34 and becomes the first. The rainwater that flows out of the side wall 31 from the water passing part 38 passes through the second water passing part 39 and falls to the ground from a position below the side pad 31 and the ceiling part 40. In FIG. 8, the flow of rainwater is schematically shown by arrows. Further, since the tip 37c of the heel portion 37b of the second member 37 is located at a position lower than the inner edge portion 36c of the notch 36b of the first member 36, the fallen leaves floating on the surface of the rainwater accumulated in the recumbent vessel 31 are It suppresses entering into the 1 water flow part 38, and becoming blocked.

  As described above, according to the present embodiment, when the rainwater in the side wall 31 exceeds the upper limit height set lower than the upper end of the side wall 31, the rainwater exceeding the upper limit height becomes the side wall 31 by the drainage unit 35. Discharged outside. Then, the rain water in the recumbent vessel 31 is guided out of the recumbent vessel 31 by the first water passing unit 38 and the second water passing unit 39 of the drainage unit 35 and dropped from a position below the recumbent vessel 31. Since it did in this way, since rainwater reliably falls from the 2nd water flow part 39, without transmitting the outer surface of the rain gutter 30, while being able to recognize clogging of the rain gutter 30 easily, from an unspecified location Can prevent the rainwater from falling.

  Further, a cap member 34 that closes one end portion of the horizontal bar 31 is further provided, and a drainage portion 35 is provided in the cap member 34. In the case of a recumbent fence 31 that has been formed with a uniform cross-section by extrusion, the upper limit height was exceeded when a part of the rainwater in the recumbent body 31 exceeded the upper limit height set lower than the upper end of the recumbent body 31. In order to provide a drainage means for discharging rainwater to the outside of the recumbent 31, a separate process is required. Alternatively, the sheet metal material may be formed by pressing or the like. Therefore, the cap member has a higher degree of freedom with respect to the shape at the time of molding as compared with the horizontal bar 31, and thus the drainage part 35 as the drainage means can be easily provided.

  Moreover, the 1st water flow part 38 and the 2nd water flow part 39 of the drainage part 35 are comprised with the pipe line. For this reason, for example, when rainwater is transmitted to the surface, there is a risk of rainwater separating from the surface and splashing over a wide area if there is momentum in the rainwater. Can be suppressed.

  In addition, the carport 1 includes a roof portion 20, a rain gutter 30 having a reed 31 that receives rainwater falling from the roof 20, and a ceiling 40 disposed below the roof 20 and the recumbent 31. The second water passage portion 39 of the drainage portion 35 of the rain gutter 30 is configured to drop rainwater guided to the first water passage portion 38 from a position below the ceiling portion 40. In the carport 1, a configuration may be adopted in which the roof portion 20 and the recumbent 31 are covered with the ceiling portion 40 so as not to be viewed from below in order to improve design properties. In such a configuration, it is conceivable that rainwater overflowing from the side wall 31 falls on the ceiling portion 40, flows on the ceiling portion 40 and falls from an unspecified location to the ground. Therefore, the second water flow portion 39 of the drainage portion 35 is configured to drop the rain water guided to the first water flow portion 38 from a position below the ceiling portion 40, so that the rain water is outside the rain gutter 30. And since it falls to the ground from the 2nd water flow part 39 reliably without passing along the ceiling part 40, while being able to recognize the clogging of the rain gutter 30 easily, the fall of the rain water from an unspecified location can be suppressed.

  As mentioned above, although this invention was mentioned and mentioned with preferable embodiment, the rain gutter and outdoor structure of this invention are not limited to the structure of these embodiment.

  For example, in the embodiment described above, the drainage portion 35 is provided in the cap member 34 that closes the end portion of the recumbent rod 31, but is not limited thereto.

  For example, a rain gutter 30A shown in FIG. 11 is provided with a tubular drain pipe 55 as a drain means fixed through the bottom wall portion 32 of the horizontal gutter 31. The upper end of the drain pipe 55 is positioned lower than the upper end of the side wall portion 33 of the horizontal bar 31. Further, the lower end of the drain pipe 55 is positioned lower than the bottom wall portion 32 of the horizontal bar 31. The inside of the portion of the drainage pipe 55 located inside the horizontal gutter 31 is the first water flow part 58, and the inside of the part of the drainage pipe 55 located outside the horizontal gutter 31 is the second water flow part 59. In the rain gutter 30A, when the height of rainwater accumulated in the horizontal gutter 31 exceeds a predetermined upper limit height (that is, the height of the upper end of the drain pipe 55), the rain water exceeds the upper end of the drain pipe 55 and the drain pipe 55. , Flows through the drain pipe 55, and falls to the ground from a position below the reed 31.

  Or, for example, in the rain gutter 30B shown in FIGS. 12A and 12B, a drainage port 68 penetrating the inside and outside of the horizontal gutter 31 is formed at a position lower than the upper end of one side wall 33 of the horizontal gutter 31. A columnar water guide portion 69 extending in the vertical direction from directly below the drain port 68 to below the bottom wall portion 32 is provided integrally with the outer surface of the one side wall portion 33. The drainage port 68 and the water conveyance unit 69 constitute a drainage unit 65 as a drainage unit, the drainage port 68 is a first water flow unit, and the water conveyance unit 69 is a second water flow unit. In the rain gutter 30B, when the height of rain water accumulated in the side gutter 31 exceeds a predetermined upper limit height (that is, the height of the drain port 68), the rain water flows out of the gutter 31 from the drain port 68, It passes along 69 and falls to the ground from a position below the reed 31. In place of the horizontal gutter 31, a cap member that closes the end of the horizontal gutter 31 may be provided with the same thing as the drainage port 68 and the water guide part 69 as a drainage part. The rain gutter 30A and the gutter 30B also have the same effects as the gutter 30 of the embodiment described above.

  In the above-described embodiment, the first water flow portion 38 and the second water flow portion 39 of the drainage portion 35 are both configured by pipes, but the present invention is not limited to this, and the first water flow portion Only one of 38 and the 2nd water flow part 39 may be comprised by the pipe line.

  In the above-described embodiment, the carport 1 has the configuration including the ceiling portion 40, but the configuration is not limited thereto, and the configuration without the ceiling portion 40 may be used. In this case, the drainage part 35 of the rain gutter 30 should just be comprised so that rain water may fall from the downward direction from the horizontal gutter 31. FIG.

  In the above-described embodiment, the carport is described as an example of the outdoor structure. However, the present invention is not limited to this. For example, the outdoor structure is provided with a rain gutter such as a terrace. The present invention can be applied.
