Description

[Detailed description of the invention] This invention is a rain gutter designed to prevent eaves gutter from meandering and detachment phenomenon caused by expansion and contraction of eaves gutter due to temperature changes, especially installed on both side walls of the water collector body. The end of the eaves gutter inserted into the eaves gutter insertion opening has substantially the same cross-sectional shape as the eaves gutter, and eave gutter edge fitting parts are provided on both sides thereof, and a drainage port is provided approximately in the center. This invention relates to an improvement in rain gutters that are slidably connected using adapters, and its purpose is to prevent water leakage from the joints due to back leakage.

Rain gutters, especially eaves gutters made of synthetic resin, expand and contract significantly due to temperature changes, so they are prone to meandering and other deformations, as well as separation phenomena at connections. The eaves gutters were generally cut inside the water collector, but in the former case, the construction was complicated, while in the latter case, the eaves gutters were not necessarily detached due to shaking of the water collector due to wind, etc. I couldn't say it was satisfactory.

Therefore, the ends of the eaves gutter inserted into the eaves gutter insertion openings provided on both side walls of the water collector body are made to have approximately the same cross-sectional shape as the eaves gutter, and the eaves gutter edges are formed on both sides of the eaves gutter. A rain gutter has been devised in which a fitting part is provided and a drain port is provided approximately in the center, and the gutter is slidably connected to the adapter. Due to this, problems such as rainwater leaking from the joints and drainage holes and flowing out of the water collector body were inevitable.

The present invention has been devised in view of the above, and below, an embodiment of the present invention shown in the drawings will be described. It is an adapter that is installed inside the water collector body, and is composed of a plate body that is curved or bent so that the cross-sectional shape is approximately the same as that of the eaves gutter to be connected, and C is the water collector body. An eaves gutter that is inserted into the eaves gutter insertion opening of A,
Although the drawing shows a semicircular gutter, it may be a square gutter or a boat-shaped gutter.

Next, reference numeral 1 denotes an opening for insertion of the eaves gutter formed on the side wall surface of the water collector main body A, which is opened to match the shape of the eaves gutter C, and 2 is an opening for passing through the eaves gutter C. 3 is a drain pipe formed at the bottom of adapter B, 3 is an eaves gutter edge fitting part provided on both sides of adapter B, and 4 is a drain hole bored approximately in the center of adapter B. , 5 are grooves formed in the inner circumferential surface of the adapter B by protruding in the outer circumferential direction along the width direction near both sides, and 6 is a small hole bored in the bottom of the groove 5.

As is clear from the above, the present invention allows the ends of the eaves gutter C inserted into the eaves gutter insertion openings 1 provided on both side walls of the water collector body A to have a cross-sectional shape that is approximately the same as that of the eaves gutter. In the case where the adapter B is slidably connected with the eaves gutter edge fitting portion 3 on both sides and the drain port 4 is provided approximately in the center, the area near both sides of the adapter B is The groove 5 is formed on the inner circumferential surface of the steel 5 by extending it in the outer circumferential direction along the width direction, and a small hole 6 is bored in the bottom of the iron 5. The rainwater flows into the groove 5 and is drained from the small hole 6 into the water collector body A.
Also, some of the rainwater drained from drain port 4 is drained from adapter B.
However, since this rainwater is drained on the outer circumferential surface of the groove 5 formed by the actual gap, there is no possibility of water leakage caused by back leakage, which is conventionally seen. This prevents them from colliding.
