Therefore, it is unlikely that the rainwater reaches the front surface of the lower wall portion 61 via the entering wall portion 64, then travels down the lower wall portion 61, and reaches the bottom wall portion 4.

By the way, when the rainwater W drained at the front portion 67a of the recessed portion 67 of the entry wall portion 64 falls, the rainwater W does not fall directly below the front portion 67a but is illustrated by an arrow a in FIG. It falls while wrapping a little backward as you did. Even in such a case, the concave portion 67 is not
Is provided in front of the foremost point P (see FIG. 1) in the connecting portion between the lower wall portion 61 and the lower wall portion 61, so that the rainwater falling is attached to the connecting portion and reaches the bottom wall portion 4. It is unlikely that it will fall down. This is useful in suppressing a situation in which dust carried by rainwater on the bottom wall portion 4 remains as dirt such as black lines and white lines.

Further, since the eaves gutter fixture 100 is constructed so as not to be immersed in the rainwater flowing through the eaves gutter 200, solids such as leaves of the tree flowing together with the rainwater in the eaves gutter 200 are applied to the eaves gutter fixture 100. Even when the eaves gutter fitting 100 is made of metal, the situation that the eaves gutter fixture 100 is wet and rusts with rainwater flowing in the eaves gutter 200 does not occur. And eaves gutter 200
Has a shape in which the lower wall portion 62 of the front rising wall portion 6 is inclined rearward as it goes upward, so that the bottom wall portion 4 is compared with the conventional example described with reference to FIGS. 6 and 7. It protrudes forward and becomes wider. Therefore, there is an advantage that the amount of rainwater flowing through the eaves gutter 200 is larger than that of the conventional example.

In this embodiment, the entrance wall 64 of the eaves gutter 200 is inclined downward and backward toward the rear. However, the entrance wall 64 is inclined horizontally and upwardly toward the rear. May be. Further, although the locking piece 15 of the holding rod 1 is cut and raised, it may be a projection or a separate member may be attached to constitute a portion corresponding to the locking piece. The protrusion length A2 of the upper locking surface 71
In the eaves gutter 200 in which the protruding length A1 of the lower locking surface 66 is set to the above-described size, the front-rear width of the bottom wall 4 is set to 120 mm, and the front end of the wall 64 is inserted from the bottom wall 4. Up to 37.5 mm, the height difference between the base and the tip of the entry wall 64 is 2.5 mm, the vertical height of the upper wall 62 is 80 mm, and the front rising wall including the front edge 7. 6 can be set to 120 mm.

Until the eaves gutter fitting 10 is suspended by the holding portion 16.
0 rising rod portion 13 and lower piece portion 92 fit into a space surrounded by upper wall portion 62, lower locking surface 66, and upper locking surface 71, and lower piece portion 92 becomes lower locking surface 66. Further, the corners of the falling portion 91 and the lower piece portion 92 engage with the ridge 68 to bring the lower end portion 13 a of the rising rod portion 13 into contact with the upper wall portion 62 of the eaves gutter 200.

The eaves gutter 200 is thus attached to the eaves gutter fixture 1
00, the upper surface 1 of the projecting piece 14 provided at the upper end of the rising rod 13 in the eaves gutter fixture 100.
4a and a lower piece 92 connected to the lower end 13a of the rising rod 13 constitute an upper locking surface 71 and a lower locking surface 66 of the eaves gutter 200.
And the lower piece 92 is in contact with the upper wall 62 of the eaves gutter 200 and the ridge 68.
Are fitted without forming a play gap in the front-rear direction between them. Further, the protruding piece portion 14 is fitted between the upper wall portion 62 of the eaves gutter 200 and the locking piece portion 72 without forming an excessively large play gap in the front-rear direction.

Therefore, the upper wall portion 62 of the eaves gutter 200 is held without rattling in the up-down direction and the front-back direction. Therefore, no matter which direction the wind pressure is applied to the eaves gutter 200, the front part of the eaves gutter 200 is attached to the eaves gutter fixture 1.
The situation of leaving from 00 is unlikely. Further, the projections 68 prevent the lower locking surface 66 and the lower piece portion 92 from slipping and becoming difficult to separate, which further increases the separation of the eaves gutter 200 from the eaves gutter fixture 100 as described above. Helps to ensure prevention. In addition, eaves gutter 2 at the time of rain
The rainwater that has fallen on the front surface of the upper wall portion 00 is drained at the lower end, which is the foremost point Q of the upper wall portion 62, which coincides with the front end of the entrance wall portion 64, so that the rainwater falls from that position. . Moreover, even if the rainwater that has been drained at the lower end of the upper wall portion 62 falls and falls while wrapping around backward, the foremost point Q of the upper wall portion 62 is set to the bottom wall portion 4 and the lower wall portion 6.
By being provided in front of the foremost point P in the connection point with the first connection point 1, it is unlikely that rainwater falling will adhere to the connection point and fall down to the bottom wall portion 4. This is useful in suppressing a situation in which dust carried by the rainwater on the bottom wall portion 4 remains as dirt such as black lines and white lines. For this reason, the lower wall portion 61 of the eaves gutter 200
Is located rearward toward the top, that is, the lower side of the lower wall portion 61 is projected forward, so that the amount of rainwater flowing in the eaves gutter 200 can be increased. Nevertheless, as described above, It is less likely that the falling rainwater will adhere to the above-mentioned connecting portion and travel down to the bottom wall portion 4.

The rainwater flowing through the eaves gutter 200 is attached to the eaves gutter fixture 10.
0 is not pickled at all, so eaves gutter 2
In the case where the solid material such as the leaves of the tree flowing together with the rainwater is caught on the eaves gutter fitting 100 and accumulates, or the eaves gutter fixture 100 is made of metal,
The above-described operation described with reference to FIG. 1 and the like, such as an operation in which 00 does not get wet and rusted by rainwater flowing in the eaves gutter 200, is also exerted by this embodiment.

In the eaves gutter of the present invention, the ridge 68 described above is used.
Can be omitted, and the locking piece 15 is not required for the eaves gutter attachment for attaching the eaves gutter with the ridge omitted. Further, the projecting piece 14 of the eaves gutter attachment may be omitted.

[0042]

According to the eaves gutter and the eaves gutter fixture of the present invention, the upper eaves gutter provided with the eaves gutter, the lower eaves and the eaves gutter provided on the upper eaves surface are provided. The element provided on the front rising wall of the eaves gutter and the vicinity thereof and the element provided on the front part of the eaves gutter such as the rising rod provided on the eaves gutter attachment and the front end of the holding rod. The cooperation prevents the eaves gutter from rattling in the vertical direction at the front part thereof. And
If a protrusion is provided on the lower locking surface of the eaves gutter and a locking piece is provided on the eaves gutter attachment, or a protruding piece is provided on the eaves gutter attachment, the eaves gutter can be moved vertically at the front part Also, rattling in the front-back direction is suppressed. Therefore, no matter which direction the wind pressure is applied to the eaves gutter, it is difficult for the front part of the eaves gutter to rattle or to be detached from the eaves gutter attachment, so that the eaves gutter construction can be performed more reliably. These effects are:
The protrusion length of the lower locking surface of the eaves gutter is longer than the protrusion length of the upper locking surface, and the locking width between the lower locking surface and the front end of the holding rod of the eaves gutter mounting is widened. The effect is more remarkably exhibited.

Further, since the eaves gutter fixture is not immersed in the rainwater flowing through the eaves gutter, solids such as leaves of the tree flowing together with the rainwater in the eaves gutter are caught and deposited on the eaves gutter attachment. Such a situation and a situation in which the eaves fitting is wet and rusted by rainwater flowing in the eaves gutter are prevented.

[0044]

According to the eaves gutter having the structure described in claim 2,
Since the foremost point of the upper wall is located ahead of the foremost point of the continuous portion of the bottom wall and the lower wall, rainwater that has fallen along the upper wall is located at the forefront of the upper wall. Since the rainwater that has been drained at the place and the drained water falls onto the ground without adhering to the lower wall, the black and white lines due to the adhesion of dust to the bottom wall of the eaves gutter are less likely to be stained.

Further, according to the eaves gutter of the present invention, since the bottom wall portion projects forward and becomes wider than that of the conventional example described with reference to FIGS. 7 and 8, the amount of rainwater flowing through the eaves gutter is reduced. The number is larger than that of the conventional example.
