Description

[Detailed description of the invention] The present invention provides a concave groove 8 on the lower periphery of the semicircular water stop plate 1 into which the end edge of the eaves gutter 4 having a substantially U-shaped cross section is fitted, and on both sides of the water stop plate 1. The edges are formed with fitting ears 2, 2 having a C-shaped cross section and facing inward and opening into which the ears 5 provided on both upper edges of the eaves gutter 4 are fitted, and at least one fitting A movable fitting ear 3 having a C-shaped cross section is formed below the fitting ear 2 and opened inward, and a transverse cut 6 is formed at the boundary between the movable fitting ear 3 and the fitting ear 2. This relates to a water stopper for eaves gutters, which is provided with a vertical cut 7 continuous with a horizontal cut 6 at the boundary between the rear end of the movable fitting ear part 3 and the water stop plate 1.

“Eave gutters are made in two sizes, large and small, depending on the amount of rainfall, and for this reason, the water stopper attached to the edge of the gutter also needs to be of two sizes, large and small, which complicates production management. In addition, the dimensions had to be checked each time during construction, which was complicated.

The present invention was devised in view of the above points, and its purpose is to provide a water stopper for eaves gutters that can be used commonly for two types of eaves gutters, large and small. To explain in detail based on an embodiment, reference numeral 1 in the figure is a water stop plate molded from synthetic resin, which has a semicircular shape, and has a groove 8 on its lower periphery, and on both upper edges. Fitting ears 2, 2 each having a C-shaped cross section and facing each other inwardly are formed integrally with each other.

This fitting ear part 2 has a concave groove 8 along the edge of the eaves gutter 4 having a U-shaped cross section.
When the eaves gutter 4 is fitted into the eaves gutter 4, the ears 5 formed by bulging out over the entire length are fitted into the upper edges of both sides of the eaves gutter 4. One of the pair of fitting ears 2, 2 A movable fitting ear portion 3 having a C-shaped cross section and opening inward is formed integrally with the waterstop plate 1 below.

This movable fitting ear portion 3 is separated from the upper fitting ear portion 2 by a horizontal cut 6, and the movable fitting ear portion 3
Also at the boundary between the inner end of the water stop plate 1 and the water stop plate 1, it is separated from the water stop plate 6 by a horizontal cut 6 and a continuous vertical cut 7, and only the lower edge of the movable fitting ear 3 is stopped. It is continuous with the water plate 1, and for this reason, the movable fitting ear 3 uses its lower edge as a fulcrum and moves outward independently of the upper fitting ear 2, utilizing the springiness of the synthetic resin. When the movable fitting ear part 3 opens outward in this way, the locking piece 9 extending from the upper edge of the movable fitting ear part 3 locks under the fitting ear part 2. It locks onto the edge and prevents it from opening any further outward.

In other words, if the eaves gutter 4 is large, the edges of the eaves gutter 4 are fitted into the grooves 8, and the ears 5, 5 on both sides of the eaves gutter 4 are fitted into the fitting ears 2, 2. A water stop plate 1 is attached to the end, and at this time, as shown in FIG. 4, the movable fitting ear 3 opens outward and prevents the engagement between the ear 5 and the fitting ear 2. If the eaves gutter 4 is small, its edge should be fitted into the groove 8 as well, and one ear 5 should be used as the fitting ear 2, and the other ear 5 should be used as the movable fitting ear. The water stop plate 1 is fitted to the end of the eaves gutter 4 by fitting into the part 3.

In the illustrated example, the vertical cut 7 is cut further below the boundary between the rear end of the movable fitting ear 3 and the water stop plate 1, but this reduces the flexibility of the movable fitting ear 3. Even if only the lower edge of the movable fitting ear part 3 is made of soft synthetic resin to further improve the performance, the movement of the movable fitting ear part 3 can be made smooth.

In addition, the material may be a vinyl chloride steel plate, a copper plate, an aluminum plate, or the like.

Since the present invention has the above-mentioned configuration, it is possible to connect two sizes of eaves gutters to one water stopper, and it is possible to produce water stoppers of two sizes depending on regions with different rainfall amounts. There is no need to do this, and a single product can be used, which has the advantage of reducing manufacturing costs and eliminating mix-ups during shipping and construction.
