Description

[Detailed explanation of the idea] The present invention relates to a telescopic rain gutter joint.

It has been well known that rain gutters made of hard material 1, such as hard synthetic resin, expand and contract.

Particularly in the case of eaves gutters, in the summer the rain gutters may stretch due to the heat of the sun, causing them to meander, and in the winter, the rain gutters may shrink and come off the joints, or the joints may be damaged.

As a countermeasure, a joint was devised to absorb the expansion and contraction of the rain gutter.

Among them, as shown in Figure 1A, there is a bellows-shaped part on the part that expands and contracts, as shown in Figure 1B.
When the eaves gutter stretches and the bellows part shrinks and folds, the mountain part of the bellows part becomes higher than the eaves gutter, which has the disadvantage of obstructing the flow of rainwater.

This invention was made in view of the above points,
The purpose is to provide a telescopic rain gutter joint that does not prevent the flow of water such as rainwater.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to drawings showing embodiments thereof.

FIG. 2 is a perspective view of the present invention.

A is the eaves gutter, and 1 is the expandable rain gutter joint.

The expandable rain gutter joint 1 has the same shape as the eaves gutter A, which is formed in a substantially semicircular shape along the outer periphery of the eaves gutter A, for example.

Further, if the eaves gutter is formed in a substantially rectangular shape, the expandable rain gutter joint 1 is formed in a shape along the outer periphery of the eaves gutter.

A telescopic rain gutter joint 1 is formed of a joint body 2 and a telescopic absorbing portion 3.

The joint body 2 is made of, for example, hard synthetic resin,
It has a roughly eaves gutter shape.

An expandable/contractable absorbing portion 3 is arranged along the inner peripheral surface 21, and is provided so as to be movable according to the expansion or contraction of the eaves gutter when the eaves gutter is joined.

The expandable/contractable absorbing part 3 is made of, for example, a soft synthetic resin, and has a bellows part 31 that can be expanded and contracted approximately at the center, and gutter bonding parts 32 and 33 for joining the eaves gutter A at both ends thereof. has been done.

Then, when the eaves gutter A is bonded and connected to the gutter adhesive parts 32 and 33 with adhesive etc., when the eaves gutter A expands, the bellows part 31 contracts and absorbs the elongation of the eaves gutter. 1
This will prevent meandering of eaves gutters.

In the joint body 2, a recessed portion 22 is formed on the inner peripheral surface corresponding to the position of the bellows portion 31, that is, on the bottom surface.

This recessed portion 22 is formed when the eaves gutter is expanded and the bellows portion 31 is contracted when the eaves gutter is joined to the joint as described above. When it is stored, the upper peak will be higher than the eaves gutter, which will obstruct the flow of rainwater and other water.

It is preferable that the width of the recessed portion 22 substantially match the width of the bellows portion.

, Figure 3 is a sectional view of the operating state when eaves gutters A and A are connected to the expandable rain gutter joint 1, and Figure 3 A is a diagram showing the normal state. This is a diagram showing a state in which when the gutter A is extended, the elongation is absorbed by the bellows part 31, and FIG. FIG.

Then, either one of the gutter bonding parts 32 and 33 of the elastic absorption part 3, that is, the gutter bonding part 32, is fixed to the inner circumferential surface 21 of the joint body 2, and the other is in a free state, that is, the gutter bonding part 33 is fixed to the inner peripheral surface 21 of the joint body 1. It may be fixed to the inner circumferential surface and left in a floating state. In that case, when the bellows part 31 is folded and contracted, the lower peak part of the bellows part 31 is reliably accommodated in the recessed part 22. That will happen.

Then, the bellows part 31 on the inner surface of the elastic absorption part 3 and the gutter adhesive part 3
2.33 may be formed with a protrusion 3434 that is shorter than the wall thickness of the eaves gutter A. In that case, the eave gutter A, A may be attached to the protrusion 34.34 during construction. The eave gutter A can be positioned in contact with the eave gutter A, and joining can be easily performed.

The expandable rain gutter joint according to the present invention has a bellows section that can be expanded and contracted at approximately the center, and expandable absorbing parts that serve as gutter adhesive parts that connect the gutter at both ends, and are shaped along the outer periphery of the gutter. The inner periphery of the joint body corresponding to the position of the bellows part is recessed to form a recessed part, and it is joined to the gutter adhesive part of the eaves gutter. Since the upper surface of the crest of the bellows part is not higher than the inner surface of the eaves gutter when the bellows expands and contracts, it has the advantage of not interfering with the flow of water such as rainwater.
