Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a rain gutter that is attached to the eaves of a building or the like by an internal hanging type gutter lifting device.

(Prior Art) There is a type of rain gutter that can be attached to an internal hanging type gutter lifting device. Conventionally, this type of rain gutter is, for example, an actual open gutter.
As described in Japanese Patent Laid-Open No. 62-4529, a gutter ear is formed in a groove shape having an opening on the inner side surface and a downward piece on the upper edge of the opening.

By the way, if the surface of the building to which the gutter hangers are fixed (for example, the front of the nose cover) is not flat, the rain gutter will be installed in a flexed state in the axial direction, so it will be continuously horizontal to the gutter ear. The load will act, and also
Even in a flat area with a fixed gutter suspension, even in a cold area with a large amount of snow or in a windy coastal area, horizontal load is intermittently applied to the gutter ear due to snow load or wind pressure.

That is, in the conventional rain gutter, the downward locking piece is locked to the gutter suspension in preparation for the above situation.

(Problems to be solved by the invention) However, in the conventional rain gutter, when a horizontal load acts on the gutter ear, the horizontal load concentrates on the downward piece,
The downward piece may be largely deformed and fall out of the gutter hanger, and the repeated downward deformation may cause fatigue and damage of the downward piece.

The rain gutter of the present invention aims to improve the attachment strength to the gutter attachment and the durability of the gutter ear by focusing on the above conventional problems.

(Means for Solving the Problems) In order to achieve the above object, the rain gutter of the present invention is provided with a trough having a U-shaped cross section having an opening on an inner side surface at an upper end of a front side wall. The upper portion and the lower edge of the portion are formed with a downward piece and an upward piece, which are engaged with the rear side surfaces of both engaging pieces provided on the upper and lower surfaces of the front end of the gutter hanger, respectively, along the longitudinal direction. As a result, the upward piece is formed of a spring plate having a thickness smaller than that of the front side wall.

(Operation) In the rain gutter of the present invention, a gutter ear having a U-shaped cross section having an opening on the inner side surface is formed at the upper end of the front side wall, and the opening has a gutter hanging at its upper and lower edges. Since the downwardly facing pieces and the upwardly facing pieces that are locked by the rear side surfaces of both locking pieces provided on the upper and lower surfaces of the tool front end portion are formed continuously along the longitudinal direction, respectively, the width is narrowed. When attaching the gutter ears to the inner hanging type gutter suspension, both the downward facing pieces and the upward facing pieces can be locked.

Then, in such an attached state, since the horizontal load acting on the gutter ear is distributed to the downward piece and the upward piece, each of the downward piece and the upward piece has a smaller deformation amount due to the horizontal load than the conventional one. It will be smaller and the gutter will be less fatigued.

In addition, the rain gutter of the present invention is formed by a spring plate whose upper piece is thinner than the thickness of the front side wall, so that when the gutter ear is attached to the gutter suspension, the upper piece is opened. Can be elastically deformed.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings.

 First, the configuration of the embodiment will be described with reference to FIG.

 FIG. 1 is a perspective view showing a rain gutter A according to an embodiment of the present invention.

The rain gutter A comprises a flat bottom wall 1, front and rear side walls 2 and 3 standing on both sides of the bottom wall 1, front ears 4 formed at the upper end of the front side wall 2, and a rear side wall. 3 and a rear ear 5 formed on the upper end of the upper end 3 of the hard disk 3 and formed of, for example, a hard vinyl chloride resin by extrusion molding.

The front ear 4 has a U-shaped cross section, has an opening 41 on its inner side surface, and has a downward piece 42 continuously formed along the longitudinal direction at the upper edge of the opening 41. In addition, the opening 41 has a narrow width by having an upward piece 43 formed continuously along the longitudinal direction at the lower edge of the opening 41. On the other hand, the rear ear 5 is formed in a closed cross section having a rectangular cross section.

The upward-facing piece 43 of the front ear 4 is integrally formed with the front side wall 2 from the same material as the front side wall 2, and is formed of a resin spring plate thinner than the front side wall 2. . Since the thickness of the downward piece 42 is almost the same as the thickness of the front side wall 2, as a result, the thickness of the upward piece 43 is thinner than the thickness of the downward piece 42.

 Next, the operation of the embodiment will be described with reference to FIG.

FIG. 2 is a cross-sectional view showing a state in which the rain gutter A is attached to an inner suspension type gutter suspension B.

The gutter hanger B is a stainless steel gutter hanger and is equipped with a mounting rod 6
And a support rod 7 and a spring plate 8. The mounting rod 6 is provided with a fixing portion 61 that is fixed to a surface (not shown) of a building such as a nose cover plate, and the front end of the support rod 7 is an upward locking piece 71 that is raised upward. And a downward locking piece 72 that is cut and raised downward. Also,
The spring plate 8 is bent in the middle so that the lower half portion 81 is fixed to the fixing portion 61 of the mounting rod 6 and the upper half portion 82 is free to tilt forward.

Therefore, when the front ear 4 of the rain gutter A is attached to the gutter suspension B, the downward piece 42 of the front ear 4 is locked by the upward locking piece 71 of the support rod 7 and the front ear 4 of the front ear 4 is attached. The tip of the support rod 7 is pushed and inserted into the front ear 4 so that the upward piece 43 is engaged with the downward engagement piece 72 of the support rod 7. Here, when the tip of the support rod 7 is inserted into the front ear 4, the upward piece 43 of the front ear 4 is formed of a spring plate in the present embodiment, so that the upward piece 43 spreads so that the opening 41 expands. Since it can be elastically deformed, the front ear 4 can be attached to the gutter suspension B with a small force, and the workability at the time of construction is good.

When attaching the rear ear 5 of the rain gutter A to the gutter suspension B, the rear ear 5 is lifted so that the lower surface of the rear ear 5 is locked to the upper end of the spring plate 8.

Then, in such an attached state, the front ear 4
Since the horizontal load acting on is distributed to the downward piece 42 and the upward piece 43, the deformation amount of each piece of the downward piece 42 and the upward piece 43 due to the horizontal load is smaller than that of the conventional one, and the front ear 4 is Fatigue is reduced. Therefore, since the attachment strength of the front ear 4 to the gutter suspension B is improved, even if there is some unevenness on the surface of the building to which the gutter suspension B is fixed (for example, the front surface of the nose cover plate), the front ear 4 remains It will not fall off from the gutter hanger B,
Further, the front ear 4 does not easily fall off the trough suspension B even by snow load or wind pressure. Moreover, the durability of the front ear 4 is also improved.

The embodiment of the present invention has been described in detail above with reference to the drawings.
The specific configuration is not limited to this embodiment, and even if there are design changes and the like within the scope of the present invention, they are included in the present invention.

For example, in the embodiment, the rain gutter in which the upward piece is integrally formed of the same material as the front side wall is taken as an example.
It may be formed separately from the front side wall, or may be formed of a material different from that of the front side wall such as a metal spring plate.

(Effect of device) As described above, in the rain gutter of the present invention,
Since the gutter ears can be attached to the gutter suspension so that the horizontal load is distributed to the upward facing piece and the downward facing piece, the amount of deformation of each piece of the upward facing piece and the downward facing piece due to the horizontal load is reduced, and the mounting strength for the gutter hanging equipment is reduced. And the fatigue of the gutter ears due to the deformation of each piece is reduced, and the durability of the gutter ears is improved. As a result, even if an external load such as snow load or wind pressure acts on the gutter horizontally, it is possible to reliably prevent the gutter from falling off the gutter suspension.
