BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gutter lid, and more particularly to a gutter lid formed of synthetic resin.

[0002]

2. Description of the Related Art Conventionally, there has been known a gutter lid formed of synthetic resin in order to reduce weight in place of an iron gutter lid, and one of such synthetic resin gutter lids has been known. The short side wall is provided with a substantially mossy-shaped lock hole with a horizontal front surface, and the other short side wall is provided with a nail-shaped engaging projection, and the adjacent one side groove lid lock hole is provided with the other side groove lid. There is also known a synthetic resin gutter lid in which a nail-shaped engaging projection is inserted to connect the gutter lids.

SUMMARY OF THE INVENTION For a synthetic resin gutter in which one of the above-mentioned short side walls is provided with a substantially mosquito-shaped lock hole whose front shape is lateral and the other short side wall is provided with a nail-shaped engaging projection. The lid (hereinafter, a synthetic resin gutter lid formed of synthetic resin is also simply referred to as “gutter lid”) is a nail-shaped engaging projection of one of the gutter lids that are connected and arranged. When a load is applied, the engaging projections are easily broken and damaged, the gutter lids are disconnected from each other, and when a car etc. passes, the gutter lid pops up, and the gutter lid pops out or pops up from the gutter. There is a problem such as an unexpected accident due to the gutter cover.

Further, in the above-described conventional gutter lid, the nail-shaped engaging projection of the other gutter lid is inserted and connected to the lock hole of the adjacent one gutter lid. In addition, the gutter cover must be connected to the outside of the gutter in advance and then disposed in the gutter, and the gutter cover cannot be mounted in the gap having only one space. Therefore, in such a case, the operator removes several adjacent gutter lids from the gutter one by one, connects the gutter lids outside the gutter, and then again attaches the joined gutter lids to the gutter. Therefore, it takes a considerable amount of time and labor to construct the gutter lid.

Further, since the synthetic resin gutter lid is lighter in weight and inferior in strength as compared with a metal gutter lid made of iron or the like, many drain holes cannot be provided in the gutter lid. Therefore, the drainage efficiency is low, and conversely, when water in the gutter overflows, it is difficult for water to flow out from the gutter lid, so that the water resistance causes the gutter lid to float up and flow away. There is.

An object of the present invention is to solve the problems of the conventional synthetic resin gutter lids described above, and to easily replace a damaged synthetic resin gutter lid and to improve the construction efficiency. It is to provide a synthetic resin gutter lid.
