TECHNICAL FIELD The present invention relates to a drain for eaves gutter.

[0002]

2. Description of the Related Art The conventional eaves drain for drainage is Sekiko 63-4.
As described in Japanese Patent No. 8740, a locking cylinder and a drain cylinder are formed, and this locking cylinder projects outward in a cylindrical portion having an external thread on its outer peripheral surface and an upper end portion of the cylindrical portion. The drainage cylinder is composed of a flange-shaped upper eaves gutter holding portion provided, and the drainage cylinder is provided with a female screw on an inner peripheral surface thereof, and a flange-shaped protrusion provided at an upper end of the cylinder portion so as to project outward. It consists of the lower eaves gutter holding part.

This eaves gutter drain is constructed and used by providing a through hole in the bottom plate of the eaves gutter, and contacting the lower eaves gutter holding portion of the drainage pipe with the lower peripheral edge of the through hole. Insert the tube part of the locking tube through the through hole from above the gutter, and screw the male screw of this locking tube into the female screw of the drain tube, and the upper eaves gutter holding part of the locking tube and the bottom of the drain tube. Attach the eaves trough drain to the eaves trough by sandwiching the side edge of the eaves trough with the side eaves trough holding part. Then, directly attach the downspout to the downspout connection part of the drainage pipe of the eaves drain, or attach the elbow, and attach the downspout to the tip of the elbow. Then, the rainwater flowing through the eaves gutter flows through the eaves drain to the downspout or via the elbow to the downspout. Further, a drain for eaves gutter described in Japanese Utility Model Publication No. 6-44885 is also known. In this eaves gutter drain, the drain cylinder is divided into a drain upper cylinder and a drain lower cylinder, and the drain upper cylinder and the drain lower cylinder are connected by a soft cylinder.

[0004]

However, if the former drainage for eaves gutter is connected to the eaves trough and a drain gutter is attached to this drainage for the eaves gutter, or if a drain gutter is attached via the elbow, the As a result of expansion and contraction of the eaves gutter due to the temperature difference, the eaves gutter drain, elbow, eaves gutter, etc. may be damaged. An example of this will be described with reference to FIGS. 4 and 5. In Figure 4,
The eaves gutter drain 102 is attached to the eaves gutter 101, and the elbow 103 is connected to the eaves gutter drain 102.
03, the figure which connects the vertical gutter 105 via the call gutter 104 is described.

Then, the eaves gutter 101 is caused by the temperature difference between summer and winter.
Expands and contracts along the eaves in the direction of the arrow. However, the downspout 105 attached to the wall does not move. Therefore,
A couple acts between the vertical gutter 105 and the eaves gutter 101. As a result, a force to rotate the elbow 103 acts on the connecting portion between the elbow 103 and the eaves gutter drain 102, and as shown in FIG. 5, cracks 106 are formed in the elbow 103, the eaves gutter drain 102, and the like. The entry elbow 103 and the eaves gutter drain 102 may be damaged.

In the latter eaves gutter drain, since the upper drainage pipe and the lower drainage pipe are connected by a soft tubular body, the soft tubular body expands and contracts to absorb strain due to expansion and contraction of the eaves trough. Therefore,
It is preferable because the drain for the eaves trough, the elbow, etc. are damaged, but since the soft cylinder is exposed, it is aged relatively quickly by being exposed to sunlight and the aged soft cylinder is often expanded and contracted. As a result, cracks occur in the soft cylinder, and rainwater leaks from the cracks. Therefore, an object of the present invention is to provide a durable drainage for eaves trough which does not damage the elbow, the drainage for the eaves trough, the eaves trough, etc. even if the eaves trough repeatedly expands and contracts.

[0007]

The present invention has been made to achieve the above object, and the invention according to claim 1 is for an eaves trough comprising a locking cylinder, a drainage upper cylinder and a drainage lower cylinder.
