Description

[Detailed description of the invention] The present invention relates to a rain gutter joint, and includes a bellows-like part 2 that is expandable and contractible in the longitudinal direction of the eaves-gutter joint body 1 on the inner surface of the eaves gutter joint body 1, and a bellows-like part 2 that can be freely expanded and contracted in the longitudinal direction of the eaves gutter joint body 1. A rain gutter joint in which one of the eaves gutter connecting parts 3 provided in the eaves gutter joint 3 is fixed to the inner surface of the eaves gutter joint body 1, and the outer surface part of the valley part 4 of the elastic bellows-shaped part 2 is made hard. This is related to.

In conventional rain gutter joints, the bellows-like part 2 is entirely soft, so when it expands and contracts, it tends to float up as shown in Figure 1, impeding the flow of rainwater. It tends to swell, further impeding the flow of rainwater, and also has the disadvantage that the soft part on the inner surface of the eaves/gutter joint body 1 shifts and expands/contracts, so the expansion/contraction is not smooth.

The present invention was devised in view of the above points, and its purpose is to make the valley of the elastic bellows-shaped part hard so that it will not rise or tangle during expansion and contraction. To provide a rain gutter joint that does not bulge on the inside and can be expanded and contracted smoothly.

The present invention will be explained in detail below using examples.

In the figure, reference numeral 1 denotes an eaves gutter joint main body having a U-shaped or semicircular cross section, and locking ears 7 into which the ears 6 of the eaves gutter 5 are fitted are provided on both upper sides.

Inside this eaves gutter joint body 1, a bellows-shaped part 2 having eave gutter connection parts 3 on both sides is arranged, and only one eave gutter connection part 3 is fixed to the eave gutter joint body 1 with adhesive or the like. It is.

Therefore, when the bellows-like part 2 expands and contracts, the bellows-like part 2 and the eaves gutter connecting part 3 at the other end slide along the inner surface of the eaves gutter joint body 1.

Here, in the bellows-shaped portion 2, at least the outer surface portion of the valley portion 4 is made of hard synthetic resin, and the other portions of the bellows-shaped portion 2 are made of soft synthetic resin.

In addition, the movable side eaves gutter connection part 3 is made of hard synthetic resin, and the eaves gutter connection part 3 fixed to the inner surface of the eaves gutter joint body 1 is made of hard synthetic resin, but since it is fixed, it is not soft. There may be.

Note that the eave gutter connecting portion 3 may have a U-shaped cross section as shown in FIG. 4, and the end of the eaves gutter 5 may be fitted into this U-shaped portion and joined with adhesive. Alternatively, it may be in a plate shape as shown in FIG. 6, in which case the outer surface of the end of the eaves gutter 5 is bonded to the inner surface of the eaves gutter connection part 3.

In the above embodiment, the soft synthetic resin and the hard synthetic resin are formed by simultaneous integral molding, but as shown in FIG. Good too.

Then, the ends of the eaves gutter 5 are fitted into both sides of the eave gutter joint body 1, and the end of one eave gutter 5 is fixed to the eaves gutter connection part 3 fixed to the eave gutter joint body 1, and the end of the eave gutter 5 is fixed to the eaves gutter connection part 3 fixed to the eave gutter joint body 1, and The eave gutter connection part 3 with the end of 5 free from the eave gutter joint body 1
The eaves gutter 5 is connected to the eaves gutter joint body 1 by fixing the eaves gutter to the eaves gutter joint body 1.

When the eaves gutter 5 expands and contracts due to changes in outside temperature, the bellows-like part 2
By expanding and contracting, it absorbs the expansion and contraction of the eaves gutter 5.

In this case, since the outer surface of the valley portion 4 of the bellows-like portion 2 is hard, the bellows-like portion 2 is prevented from rising as in the conventional case.

Therefore, in the present invention, as mentioned above, since the outer surface of the valley of the elastic bellows-like part is made hard, the valley can be aligned exactly with the inner surface of the eaves gutter joint body, and when it expands and contracts, It allows rainwater to flow smoothly without floating or swelling inside, and since the outer surface of the trough of the bellows is hard, it easily slips against the eaves gutter joint body when it expands and contracts. can be done smoothly.

In this way, the presence of a hard part on the outer surface of the bellows-shaped valley
Two unique effects on rain gutter joints: the ability to make the valleys fit perfectly along the inner surface of the eaves gutter joint body, which helps retain the shape of the bellows-like part, and the role of providing a sliding effect on the eaves gutter joint body when it expands and contracts. It also has the following.
