Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a metal eaves gutter, and more particularly to a metal eaves gutter of an internally suspended type in which a mounting bracket does not appear at the eaves end after construction.

[Conventional technology]

Conventionally, as this kind of metal eaves gutter, an eaves gutter having a substantially U-shaped cross-section has been used by bending the upper end portions of both side walls of the eaves gutter body and providing an edge having a hollow cross-section. In recent years, similar to synthetic resin eaves gutters, after installation, there is a need for an in-hang type in which mounting brackets do not appear at the eaves tip. In general, an opening is formed and an engaging piece is formed on the inner wall surface of the above-mentioned edge.

[Problems to be solved by the invention]

As shown in FIG. 3, the metal eaves gutter of the inner suspension type has a substantially L-shape formed at the tip of a mounting bracket at a slit-shaped opening of the metal eaves gutter and has a height equal to the opening. The locking projection is mounted by fitting a locking projection slightly higher than the portion and locking the locking projection to the locking piece.

However, in this case, the distance 1 between the upper end of the outdoor side wall of the eaves gutter body and the lower end of the locking piece is 1.5 m in the horizontal direction.
m, so that when the locking piece is deformed to the indoor side due to the work of attaching the eaves gutter to the mounting bracket at the time of construction and the vibration due to strong wind after construction, the support of the locking projection is There was a problem such as separation due to floating of the eaves gutter.

[Means for solving the problem]

The present invention has been devised in order to solve the problem of the above-mentioned conventional product, and has a substantially U-shaped cross-section at the upper end of the outdoor side wall of the eaves gutter main body having a substantially U-shaped cross section toward the indoor side. A metal eaves gutter having a locking piece hanging down from a tip of the edge of the ear, wherein a locking projection formed by bending a plate-like body into an L-shape is used as an outdoor engagement member. In a metal eaves gutter attached to a building, a horizontal piece extending toward the inside of the ear edge is extended at the tip of the locking piece, and the tip of the horizontal piece is the base end of the locking projection of the mounting bracket. The problem was solved by being brought into contact with the part.

That is, the invention according to the present application is based on the elastic force of the hanging piece only, the elastic force of the horizontal piece toward the inside of the ear edge (in other words, not only the elastic force of the bent portion which is the base end of the locking piece, but also By applying the elastic force (obtained by the bent portion between the stop piece and the horizontal piece), it has higher vibration resistance.

The length of the horizontal piece is preferably about 3 to 7 mm from the degree of deformation of the locking piece, that is, the external force applied to the horizontal piece during or after construction.

〔Example〕

Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a perspective view showing an embodiment of a metal eave gutter of the present invention, and FIG. 2 is a partially enlarged sectional view of the same.

In the figure, reference numeral 1 denotes an eaves gutter body having a substantially U-shaped cross section made of a stainless steel (SUS304) strip having a thickness of 0.3 mm.
Is an edge formed on the upper end of the outdoor side wall of the eaves gutter body 1, and has a substantially U-shaped cross section (width 10 mm, height 15 mm) toward the indoor side.
3 is a length of 12 mm which is hung from the tip of the edge 2 to the upper end of the outdoor side wall of the eaves gutter body 1.
Reference numeral 4 denotes a horizontal piece formed at the distal end of the locking piece 3 and has a length of 3 mm or 5 mm in the horizontal direction from the distal end of the locking piece 3 toward the inside of the ear edge. (L).

In the figure, reference numeral 5 denotes a slit-shaped opening having a height (h) of 3 mm, and reference numeral 6 denotes a locking projection of a mounting member 7 having a height (H) of 5 mm.

The locking projection 6 of the mounting bracket 7 is fitted into the slit opening 5 of the metal eave gutter and locked to the locking piece 3, and when the external force (f) is applied to the mounting bracket 7, the locking piece is formed. Table 1 shows the results of the measurement of the load when the locking projection 6 comes off from 3.

[Effects of the Invention] As is clear from the above, the metal eaves gutter of the present invention has a horizontal piece extending from the inside of the ear edge to the tip of the locking piece, and is the base end of the locking piece. Equipped with the elastic force of the bent part and the elastic force of the bent part between the locking piece and the horizontal piece, this greatly prevents the eaves gutter from detaching from the mounting bracket, and further increases the secondary cross-section It is also possible to improve the overall strength and prevent the occurrence of wrinkles generated in the locking pieces due to molding.
