Description

[Detailed Description of the Invention] The present invention relates to an eaves gutter that absorbs expansion and contraction and does not deform. A plurality of bent portions 3 protrude from the ears 2 of the eaves gutter body 1 over a portion of the eaves gutter body 1 in a direction substantially perpendicular to the longitudinal direction of the eaves gutter body 1.
This relates to eaves gutters that are spaced apart over approximately the entire length of the eaves.

Conventionally, eaves gutters have inevitably expanded and contracted repeatedly due to changes in temperature, causing them to bulge on both sides, and eaves gutters made of synthetic resin have been particularly susceptible to deformation.

The present invention solves the above-mentioned drawbacks, and the first purpose is to provide an eaves gutter that absorbs expansion and contraction caused by changes in temperature and does not deform. is to provide eaves gutters that can improve the appearance.

The present invention will be described in detail below with reference to a first embodiment illustrated in FIGS. 2 and 3.

The eaves gutter main body 1 is made of synthetic resin such as vinyl chloride resin and has a U-shaped cross section, and the upper ends of the eaves gutter main body 1 on the outdoor side and the eaves side each have a substantially rectangular cross section over almost the entire length. Ear portions 2 are provided.

From each ear part 2 to a part of the eaves gutter body 1 below the ear parts 2, there is a bent part 3 which is substantially perpendicular to the longitudinal direction of the eaves gutter body 1 and has a substantially V-shaped cross section. The protruding length and width of the bent parts 3 projecting outward from the eave gutter main body 1 become smaller at the lower part, and a plurality of bent parts 3 are spaced apart from each other over substantially the entire length of the eaves gutter main body 1 in the longitudinal direction.

An upper reinforcing portion 4 is formed between the upper end of the outer periphery 1 of the eaves gutter body 1 and the lower part of each ear portion 2 over approximately the entire length in the longitudinal direction of the eaves gutter body 1 excluding the bent portions 3, and the adjacent bent portions A lower reinforcing part 5 is provided on the outer circumferential surface of the eaves gutter body 1 slightly below the middle part between the three parts, and protrudes substantially parallel to the bent part 3.

Therefore, when constructing the rain gutter, the outer peripheral surface side of the eaves gutter body 1 is fitted into the receiving metal fitting 6 installed at the eaves, and the eaves gutter body 1 is fixed to the eaves. Install a water collector.

Now, when the temperature rises, the eaves gutter main body 1 made of synthetic resin with a large coefficient of thermal expansion expands in the longitudinal direction, but each bent part 3 is pressed from both sides of the eaves gutter main body 1 in the longitudinal direction, and both sides of the bent part 3 The eaves gutter body 1 is deformed so as to overlap to absorb the elongation of the eaves gutter body 1, and the eaves gutter body 1 is not deformed so as to bulge on both sides.

On the other hand, when the temperature drops, the eaves gutter main body 1 is retracted in the longitudinal direction, but each bent part 3 is pulled from both sides, and both sides of the bent part 3 are deformed into a flat plate shape, absorbing the contraction of the eaves gutter main body 1. This prevents deformation of the eaves gutter body 1.

In addition, in the first embodiment, since the upper reinforcing part 4 and the lower reinforcing part 5 are provided, the strength of the eaves gutter body 1 is improved, and even if the bending part 3 absorbs the contraction of the eaves gutter body 1, the eaves can be The gutter rod body 1 is not deformed.

FIG. 4 shows a second embodiment of the present invention, in which the bent part 3 is formed of a soft resin such as a soft vinyl chloride resin, and the lower part of the bent part 3 is made of a hard resin such as a hard vinyl chloride resin. A reinforcing protrusion 7 is formed.

In the second embodiment, the bent portion 3 is made of soft resin, so
Expansion and contraction of the eaves gutter main body 1 can be smoothly absorbed by the bending part 3, and furthermore, the eaves gutter main body 1 can be reinforced by the reinforcing protrusion 7.

Further, FIGS. 5a and 5l) show a third embodiment of the present invention, in which a cover piece 8 is attached to the inner circumferential surface of the eaves gutter body 1 to close the inner circumferential surface side of the eaves gutter body 1 of the bent part 3, This prevents dirt and water from accumulating inside the bent portion 3.

FIG. 6 shows a fourth embodiment of the present invention, in which a bent portion 3 is provided only on the easily deformed outdoor side of the eaves gutter main body 1, in which the upper end of the outdoor side is higher than the upper end of the eaves over the entire length. It was installed separately.

Furthermore, FIG. 7 shows a fifth embodiment of the present invention, in which a bent portion 3 is provided only on one ear portion 2 side of the eaves gutter body 1.

As mentioned above, the present invention has a bent part that protrudes from at least one ear provided on the eaves gutter body to a part of the eaves gutter body in a direction substantially perpendicular to the longitudinal direction of the eaves gutter body, so that Even if the eaves gutter body expands, the bent part bends further to absorb the elongation of the eaves gutter body, and the eaves gutter body does not deform to bulge on both sides.

On the other hand, even if the eaves gutter body contracts as the temperature drops, the bent part will only be pulled in the longitudinal direction of the eaves gutter body and become flat, and the eaves gutter body will not deform. It can absorb expansion and contraction.

Moreover, since multiple bent parts are spaced apart over almost the entire length of the eaves gutter body, the ability to absorb expansion and contraction of the eaves gutter body is large, and even if the eaves gutter body is made of synthetic resin that easily deforms, deformation can be prevented. Of course, the bent part can reinforce the eaves gutter body, and the bent part can also change the appearance of the eaves gutter body, making the eaves gutter body look luxurious and improving its aesthetics. It is possible.
