DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rain gutter in which a drain member is connected to a bottom surface of an eaves gutter from below, and water of the eaves gutter is drained downward through the drain member.

[0002]

2. Description of the Related Art Conventionally, as this type, there is a type provided for drainage of a roof such as a terrace or a carport, as shown in FIGS. That is, reference numeral 1 in the drawing denotes an eaves gutter having a U-shaped cross section, which is disposed along the edge of the roof (not shown), and a resin drain member 3 is attached to the eaves gutter 1 via a packing 2. Further, as shown in FIG. 8, an elbow 4 is mounted on the drain member 3, and a downspout 5 is connected to the elbow 4.

[0003] Specifically, on the bottom 1a of the eaves gutter 1,
While a long hole 1b extending in the longitudinal direction of the eaves gutter 1 is formed,
The drain member 3 is provided with a pair of elastically deformable locking pieces 3a which are locked to a linear portion 1d along the longitudinal direction of the peripheral portion 1c of the long hole 1b.

The rainwater flowing from the roof into the eaves gutter 1 is drained to a drain on the ground through a drain member 3, an elbow 4, and a vertical gutter 5.

By the way, the amount of rainwater flowing from the roof into the eaves gutter 1 has increased along with the enlargement of terraces and carports. Can not. Therefore, the eaves gutter 1 is formed with the elongated hole 1b as described above to increase the amount of water flowing to the drain member 3 side.

In the case of an arrangement in which the roof edge covers the upper side of the eaves gutter 1, the drain member 3 cannot be attached to the long hole 1b from the upper side of the eaves gutter 1, and the length of the drain member 3 cannot be increased. It is designed to be mounted from below the hole 1b.

Further, the locking piece 3a of the drain member 3 is locked to the linear portion 1d of the elongate edge 1c of the eaves gutter 1 so as not to hinder the flow of water into the drain member 3. ing. That is, the locking piece 3a is attached to the arc portion 1e of the peripheral portion 1c.
Is locked, the locking pieces 3a obstruct the flow of water, and it is difficult for rainwater to flow into the drain member 3.

[0008] Examples of this type include those described in Japanese Patent Application Laid-Open No. Sho 64-80651.

[0009]

However, in such a conventional device, the locking piece 3a of the drain member 3 is locked to the linear portion 1d along the longitudinal direction of the long hole 1b for each of the above reasons. Therefore, when an external force in the longitudinal direction of the eaves gutter 1 acts on the drain member 3, the drain member 3 may slide in the longitudinal direction, and a connection portion between the drain member 3 and the eaves gutter 1 may be formed. And there is a risk that water leaks from this portion.

It is an object of the present invention to provide a rain gutter which prevents the drain member from sliding even when an external force acts on the drain member after the drain member is attached.

[0011]

SUMMARY OF THE INVENTION The present invention has been made in view of such a problem, and a drain member is connected to a bottom portion of an eaves gutter from below, and water of the eaves gutter is lowered via the drain member. In the rain gutter designed to drain water, a long hole extending in the longitudinal direction of the eave gutter is formed on the bottom portion of the eave gutter, while the drain member has a linear portion along the longitudinal direction of the long hole peripheral portion. A locking piece for locking is formed, and furthermore, an engaging portion is engaged with the peripheral portion of the long hole, and the drain member is engaged with the engaging portion to slide the drain member in the longitudinal direction. This is characterized in that rain gutters are formed on each of the engaged portions for preventing the occurrence of the rain.

[0012]

According to this means, the locking piece of the drain member is locked to the linear portion of the elongate rim of the eaves gutter to support the drain member, and at the same time, the drain is engaged with the engaging portion of the elongate rim. The engaged portion of the member engages. Even if an external force in the longitudinal direction of the eaves gutter is applied to the drain member by the engagement between the engaging portion and the engaged portion, the drain member does not slide as in the related art. The connection with the eaves gutter is not displaced, and the occurrence of water leakage is prevented.

[0013]

Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show one embodiment of the present invention.

First, the structure will be described. Reference numeral 1 in FIG. 1 denotes an eaves gutter provided along an edge of a roof, and a drain member 11 is attached to the eaves gutter 1 via a packing 2.

More specifically, the eaves gutter 1 has a long hole 1b formed along the longitudinal direction of the eaves gutter 1, and the packing 2 also has
A long hole 2a of the same size is formed.

The drain member 11 is made of resin, and has a rectangular cover portion 11a for covering the elongated hole 1b, and a cover portion 1a.
And a cylindrical portion 11b protruding downward from 1a.
A pair of elastically deformable locking pieces 11c for locking the straight portion 1d of the peripheral edge portion 1c of the long hole are provided in the cover portion 11a.
Are protruding. Further, the drain member 11
Inside the cover portion 11a, a rib 1 as an engaged portion to be engaged with the arc portion 1e as an engagement portion of the elongated hole peripheral portion 1c.
1d is formed. The height of the rib 11d is such that the height of the rib 11d is in engagement with the arc portion 1e, and
It is set so as not to protrude above a. The engagement between the arc portion 1e and the rib 11d prevents the drain member 11 from sliding with respect to the eaves gutter 1 even when an external force acts on the drain member 11.

A pair of locking pieces 1 is placed on the drain member 11 from below the eaves gutter 1 with the packing 2 interposed therebetween.
1c is elastically deformed and locked to and supported by the linear portion 1d of the elongated hole peripheral portion 1c. At the same time as this locking, the rib 11d of the drain member 11 is locked to the circular arc portion 1e of the elongated hole peripheral portion 1c.

Even if an external force in the longitudinal direction of the eaves gutter 1 acts on the drain member 11 due to the engagement between the rib 11d and the arc portion 1e, the drain member 11 does not slide as in the conventional case. The connection between the drain member 11 and the eaves gutter 1 is not displaced, and the occurrence of water leakage is prevented.

In this embodiment, a pair of notches 1f as engagement portions are formed in the straight portion 1d of the elongate edge 1c of the eaves gutter 1, while the drain member 11 has the rib of the first embodiment. 1
Instead of 1d, a pair of projections 11e are formed on the engagement piece 11c as engaged parts.

Also in this case, the projection 11 is inserted into the notch 1f.
The engagement of the e prevents the drain member 11 from sliding.

The other constructions and operations are the same as those of the first embodiment, and the description is omitted.

As shown by the two-dot chain line in FIG. 4, the shape of the long hole 1b may be rectangular, and the notch 1f may be rectangular.

Although the protrusion 11e of the above embodiment is formed thicker than the other portion of the locking piece 11c, as a modified example, as shown in FIG. 6, the projection 11e has substantially the same thickness as the locking piece 11c. A thick protrusion 11f can also be formed.

Furthermore, although the embodiment of the present invention has been described with reference to the drawings, the specific configuration is not limited to this embodiment, and there are design changes and the like within a range not departing from the gist of the present invention. Even this is included in the present invention.
