Description

The present invention relates to eaves gutter catchment devices.

  Conventionally, in the rain gutter structure, an eaves water collector with eaves is installed between the eaves and the eaves, and rainwater flowing in the eaves is collected in the eaves to make the eaves. It can be made to flow down. In this eaves collector, the amount of water that can flow into the eaves drops due to clogging with dead leaves in the communication hole with the eaves, or the amount of water collected in the eaves collector increases during heavy rain. Then, an overflow hole may be formed in the eaves portion in preparation for the case where the inside of the eaves water collector becomes full (for example, see Patent Document 1).

However, since the overflow hole formed in the conventional flange is a substantially round shape and is provided only in the upper and lower ends of the flange, the overflow hole is overflowed from the overflow hole. The amount of rainwater that could be made was limited to a certain amount. Accordingly, there has been a problem that the rainwater flowing through the eaves is not able to cope with the case where the rainwater flowing through the eaves exceeds the predetermined amount, and the rainwater overflows from the eaves. The same problem was also a concern when the specifications were such that rainwater would be drained through a fence from one of the eaves attached to the lower end of a single-flow roof with a solar panel spread over the entire roof.
The present invention aims to provide a eaves gutters catchment device that can be made to overflow the rainwater according to rainfall.

An overflow hole is formed , a locking part is formed on one of the eaves water collector and the eaves ceiling ring, and a locked part for locking the locking part is formed on the other The eaves water collector is fixed to the eaves ceiling through the eaves ceiling ring.
According to this aspect, the overflow hole is formed continuously or intermittently from the upper end to the lower end of the overflow portion, and the opening that can overflow rainwater from the overflow hole as the water level in the heel increases. Therefore, the amount of water that overflows from the overflow hole can be increased according to the amount of rainwater.
Moreover, according to this structure, an eaves water collector can be installed in an eaves ceiling.

The outer peripheral surface of the reservoir of the eaves gutter catchment device of the present invention preferably are formed extending buildings groove downward.
According to this configuration, rainwater overflowing from the overflow hole can be guided into the concave groove and guided downward.

In this state, the anti-rotation convex portion 23b is positioned in the left-right direction of the overhang portion 37, and the hook stopper 22 is positioned further upward, so that the overhang portion 37 is fixed within the hook locking convex portion 23 of the lower ring 13. Thus, the installation of the eaves water collecting device 10 below the eaves wall 5 is completed. Then, installation of the gutter structure 1 is completed by connecting the gutter 6 to the connection part 31 of the eaves water collector 20.

Next, the operation and function of the eaves water collector 20, the eaves water collecting device 10 and the gutter structure 1 will be described.
As shown in FIG. 1, rainwater that has fallen on the roof 2 is collected in the flowing water part 3 and flows down from the open end 4 of the flowing water part 3 to the eaves 5. Since the eaves 5 is installed below the flowing water part 3 with a water gradient, the rainwater in the eaves 5 flows toward the downstream and from the opening 5h formed in the bottom plate 5a on the downstream side. It flows down into the eaves water collector 20 through the drain 7.

Thereafter, when the amount of rainfall is small, the rainwater drops along the inner wall surface of the drain 7B of the drain 7 shown in FIG. 2 and drops into the funnel portion 33 of the flange portion 30, and further, the side wall 33a and bottom wall of the funnel portion 33 33b, flows down to the eaves 6 along the inner surface of the connecting portion 31.
However, the amount of rain flowing in the eaves 樋 5 exceeds the amount of drainage per unit time of 竪 樋 6, such as during heavy rains or when rainwater flows due to the structure of the roof 2, and the water level in the heel part 30 gradually rises. When the overflow portion F is reached, rainwater that does not flow down to the trough 6 sequentially overflows from the slit 35. The rainwater overflowing from the slit 35 is guided by a concave groove 40 formed below the slit 35 and flows downward vertically, and drops onto the ground from the lower end of the side wall 32 of the collar 30.

  Further, when the amount of rainwater that cannot flow down to the dredging 6 increases rapidly, the water level gradually increases in the overflow portion F, but the slit 35 continues in the vertical direction from the upper end to the lower end of the overflow portion F. Therefore, as the water level in the overflow portion F increases, the opening area of the slit 35 increases, and a larger amount of rainwater overflows.

  As described above, according to the eaves water collector 20 and the eaves water collecting device 10, rainwater that cannot flow down to the eaves 6 can be temporarily stored in the storage portion P of the eaves portion 30. Rainwater exceeding the water level of the reservoir P can be overflowed from a plurality of vertically long slits 35 formed in the overflow portion F. Therefore, even when a quantity of rainwater that cannot be drained into the eaves 6 flows into the eaves collector 20, the rainwater can overflow from the eaves collector 20. The effect that it is possible to prevent overflowing from everywhere is obtained.

  In addition, since the slit 35 is formed vertically long in the vertical direction, the level of rainwater in the overflow portion F ranges above and below the slit 35 even when the amount of water increases beyond the storage portion P of the heel portion 30. As long as it is inside, the amount of rainwater that can overflow from the slit 35 can be increased or decreased according to the amount of rainwater that increases beyond the reservoir P. Therefore, according to the eaves collector 20, it is possible to more effectively suppress the overflow of rainwater from the eaves 5 by flexibly adapting to the rainfall.

  Furthermore, since a plurality of vertically long slits 35 are provided and these slits 35 are arranged in the overflow portion F, it is possible to prevent the overflowing rainwater from being concentrated in a specific place. It is done.

  Further, since the concave groove 40 is formed below the slit 35 on the outer peripheral surface of the side wall portion 32 of the storage portion P, rainwater overflowing from the slit 35 is passed through the same flow path, that is, the concave groove 40. You can Therefore, the external appearance of the eaves water collector 20 can be improved by retaining the easily contaminated area in the concave groove 40 without smearing the outer peripheral surface of the side wall portion 32 with rainwater. In addition, a drainer may be protruded from the lower end of the flange portion 30 on the extension of the concave groove 40.

  Moreover, since the skirt part 16 of the upper ring 12 is installed so as to reach the upper end of the storage part P of the collar part 30, by setting the colors of the collar part 30 and the upper ring 12 to be the same, the eaves basket 5 In addition to concealing the drain 7 installed on the roof, the slit 35 can be made inconspicuous, and the appearance of the gutter structure 1 can be improved.

  In addition, the skirt portion 16 protrudes downward from the outlet 7B of the drain 7 and is installed so as to substantially reach the upper end of the storage portion P of the heel portion 30, so that the rainwater flowing down from the eave ridge 5 is diffused. It is possible to reliably guide and flow down into the storage part P without causing it to occur. Therefore, it is possible to prevent the rainwater flowing down from the eaves 5 from being scattered before reaching the storage part P and being directly drained from the slit 35.

Next, a modification of the above embodiment will be described with reference to FIG. In the description of this modification, the same components as those in the above embodiment are denoted by the same reference numerals, and detailed description thereof is omitted.
The eaves water collecting device 20 and the eaves water collecting device 10 of the present modification are the same as the eaves water collecting device 20 and the eaves water collecting device 10 of the above embodiment in that the upper ring 12 is not provided with the skirt portion 16. Is different.
Thus, even if the upper ring 12 is not provided with the skirt portion 16, the drop port 7B of the drain 7 shown in FIG. 1 cannot be blinded and the slit 35 cannot be made inconspicuous. The same operations, functions, and effects as in the above embodiment are exhibited.

  In addition, in the said embodiment, although the eaves water collector 20 was set as the structure installed under the eaves wall 5 via the eaves ceiling 8, the eaves water collector 20 is set in the edge part of the eaves wall 5. It may be directly connected. In short, the operation and effect of the present invention can be achieved if the ridge portion 30 for storing rainwater flowing from the eave ridge 5 has a slit 35 formed to have a length in the vertical direction.

In addition, the slit 35 is formed with a constant width dimension, but the shape of the slit 35 gradually decreases in the width direction as it goes upward, or gradually increases in the width direction as it goes upward. Alternatively, the slits may be formed intermittently in the radial direction or circumferential direction and intermittently formed in a plurality of stages in the vertical direction. In short, when the rainwater level increases in the overflow portion F, the opening area of the slit 35 that overflows the rainwater may be configured to expand toward the upper portion of the overflow portion F.
Further, the concave groove 40 formed below the slit 35 may be formed by protruding a rod-shaped wall portion 36 in the radial direction.
As mentioned above, although embodiment of the eaves water collector 20 and the eaves water collecting apparatus 10 of this invention was demonstrated, this invention is not limited to the structure shown in the said embodiment, The meaning of this invention Changes can be made without departing from the scope.
