Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a synthetic resin eave gutter joint, and more particularly to a synthetic resin eave gutter joint capable of absorbing expansion and contraction of an eave gutter due to a change in temperature.

[0002]

2. Description of the Related Art Conventionally, as this kind of synthetic resin eave gutter joint, as shown in Japanese Utility Model Laid-Open Publication No. Sho 60-124430, the inner peripheral surface of the other end of a joint body having an eave gutter connection portion at one end is known. Generally, a joint member having an eaves gutter connection portion at one end portion slidably abutting the other end portion of the joint member via a sealing material along the width direction is generally used.

[0003]

However, in the above-mentioned synthetic resin eaves gutter, dust that has flowed down from a roof surface or the like and accumulated on the eaves gutter above the water is located on the water with the rainwater. The sliding portion of the joint member on the underwater side, which flows down and accumulates on the joint body and slides with the eaves gutter, rides on the dust accumulated on the sliding portion of the joint body and slides on the joint member. The moving part side floats up, and the dust flows into the seal material, and as a result, a gap is generated between the joint body and the joint member abutted through the seal material along the width direction, and a waterproof However, there has been a problem that the sealing material provided for the above cannot perform its function, causing water leakage.

The present invention has been devised in order to solve the above-mentioned drawbacks of the conventional product, and it is an object of the present invention to provide a synthetic resin eaves gutter joint which prevents the above-mentioned dust from flowing down and lowering the waterproof function due to accumulation. It is.

DISCLOSURE OF THE INVENTION The present invention has been devised in view of the above, and has a joint body having an eaves gutter connection at one end and a sliding portion at the other end, and an eaves at one end. A joint member having a gutter connection portion and a sliding portion at the other end, wherein the joint member is slidably abutted on the inner peripheral surface of the sliding portion of the joint body; A bellows-like membrane bent in a U-shape is stretched so as to shield between the base end of the eave gutter connection part and the free end of the sliding part of the joint member. Eave gutter joint made of synthetic resin.

The bellows-shaped covering is fixed to the base end of the eaves gutter connecting portion of the joint body and the free end of the sliding portion of the joint member by bonding, respectively. If necessary, a sealing material along the width direction may be interposed between the joint member and the joint member.

[0007]

The synthetic resin eave gutter joint of the present invention is bent into a U-shape so as to shield between the base end of the eave gutter connection part of the joint body and the free end of the sliding part of the joint member. Dust flows down from the water surface because the bellows-like covering is stretched, but the dust flows down onto the eaves gutter below the bellows through the bellows-like covering and does not necessarily require a sealing material. There is no water leakage due to the deterioration of the function of the sealing material such as the rising of the joint member caused by riding on dust from the surface.

FIG. 1 is a perspective view showing an embodiment of a synthetic resin eave gutter joint according to the present invention, and FIG. 2 is a perspective view showing an embodiment of the synthetic resin according to the present invention. It is sectional drawing which shows the use condition of one Example of eaves gutter joint.

In the figure, A has an eaves gutter connecting portion 1 provided at one end for connection of a water eaves gutter C, and a sliding portion 2 at the other end.
Is a joint body having a substantially U-shaped cross section.

In the drawing, B is a joint member having a substantially U-shaped cross section which is slidably mounted on the inner surface of the sliding portion 2 of the joint main body A, and has a water eaves gutter C at one end. An eaves gutter connecting portion 3 provided for connection is provided, and a sliding portion 4 that slides with the sliding portion 2 of the joint body A is provided on the other end side.

The base end of the eave gutter connecting portion 1 of the joint main body A and the free end of the sliding portion 4 of the joint member B have a bellows-like shape bent in a U-shape so as to shield between them. A cover film 5 is stretched, and a seal member 6 is mounted between the joint body A and the joint member B along the width direction.

[0012]

As is clear from the above description, the synthetic resin eave gutter joint of the present invention has a joint body having an eave gutter connection portion at one end and a sliding portion at the other end, and an eave gutter at one end. A joint member having a connecting portion and a sliding portion at the other end, wherein the joint member slidably abuts the inner peripheral surface of the sliding portion of the joint body; Since a bellows-shaped covering film bent in a U-shape is stretched so as to shield between the base end of the gutter connection portion and the free end of the sliding portion of the joint member, dust is collected from above the water. Dust flows down on the eaves gutter below the bellows-like membrane, and this seals the joint member that slides along with the eaves gutter seen in conventional products on the dust. Water leakage due to deterioration of the function of the material is prevented.
