Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a rain gutter mounting structure, and is particularly suitable for installing rain gutters on the eaves of houses in regions with heavy snowfall in winter. Regarding.

(Conventional technology) When installing rain gutters to the eaves of a house,
As shown in FIG. 4, the base 101 of the fixture 100 is fixed to a rafter 102 or the like at the eaves with a stopper 103, and both ear receivers 104, 104 of the fixture 100 are attached to both ears 106 of the rain gutter 105. , 106 has been widely adopted.

However, when installing a rain gutter with such a mounting structure on the eaves of a house in a snowy country where there is a large amount of snow in the winter, the following problems arise.

(Problem to be solved by the invention) In other words, in snowy countries, a large amount of snow accumulates on roofs and rain gutters 105 during the winter, but since the snow accumulated on rain gutters 105 does not flow away like rainwater, the snow load is quite large. will fall on the rain gutter 105. Therefore, if the rain gutter 105 becomes unable to withstand the load, the rain gutter 105 will be deformed and damaged, and in some cases, the fixture 100 will also be deformed from its base as shown by the dashed line in FIG. 4.

(Means for Solving the Problem) In order to solve this problem, the rain gutter mounting structure of the present invention rotatably attaches one ear of the rain gutter to a fixture fixed to the eaves. However, the other ear is configured to be attached to the fixture so as to be detached when a load greater than a predetermined load is applied.

(Operations and Effects) With this configuration, when the snow load exceeds a predetermined load, the other ear of the rain gutter separates from the attachment, and the rain gutter rotates around the one ear. Since snow accumulated in the rain gutter is removed, there is no risk of deformation or damage to the rain gutter or the attachments. After the snow has been removed automatically in this way, if you attach the other ear of the rain gutter to the mounting bracket again, you can very easily restore the rain gutter to its original installation state. It is very convenient because it can be done.

Hereinafter, the present invention will be described in detail with reference to Examples.

(Example) Fig. 1 is a cutaway explanatory diagram of the main parts showing an embodiment of the rain gutter mounting structure of the present invention, in which 1 is a mounting tool, 2 is a rain gutter, and 3 is a rafter at the eaves of a house. It shows.

This fixture 1 has a magnet 12 fixed to the lower surface of the tip of a metal plate 11 such as an iron plate bent into a "dog" shape, and a C-ring-shaped highly rigid ear receiving member 13 attached to the lower surface of the approximately intermediate portion. The base 111 of this metal plate 11 is fixed to the rafter 3 with an appropriate fastener 4.
is fixed.

On the other hand, the rain gutter 2 is made of extrusion molded synthetic resin such as polyvinyl chloride, and one of the ears 21 has a circular cross-sectional shape as shown in the figure. The ear portion 21 is fitted while sliding in the axial direction, thereby being rotatably engaged. In addition to the rotatable fastening means of this embodiment, for example, a means as shown in FIG.
It is also possible to adopt a method of hanging the hook 25 of the hanger 24 that grips the metal plate 11 on the semi-annular protrusion 14 protruding from the lower surface of the metal plate 11 of the fixture.

The other ear portion 22 of the rain gutter 2 has a rectangular cross-sectional shape as shown, and its surface is covered with a magnetically attachable metal piece 23 such as iron. This metal piece 23 is
This can be omitted if the gutter body is made of magnetic metal such as iron. Therefore, when attaching the ear part 22 to the fixture 1, the metal piece 23 is attached to the magnet 12.
This is done by magnetically attaching the ear part 22 to the magnet 12 of the fixture 1 when a load exceeding the magnetic force is applied to the rain gutter 2. The magnitude of the magnetic adhesion force is set to be smaller than the bending strength of the metal plate 11 of the fixture 1, so that the ears 22 of the rain gutter 2 are sure to separate before the metal plate 11 deforms. There is. In addition to this embodiment, other detachable attachment means for the ear portion 22 may be used.
For example, by means as shown in FIG. 3, an ear portion 22 having a circular cross section is elastically inserted from below into a C-ring shaped ear receiving member 14 made of an elastically deformable spring plate fixed to a metal plate 11 of the fixture. It is also possible to employ means for fitting.

In the rain gutter installation structure described above, when the load of snow accumulated on the rain gutter 2 exceeds the magnetic attraction force described above, the ears 22 of the rain gutter 2 are removed as shown by the dashed line in FIG. is detached from the magnet 12 together with the metal piece 22, and the rain gutter 2 rotates around the other ear part 13 that is attached to the ear receiving member 13 of the fixture 1 and automatically removes the accumulated snow. The problem of deformation or damage of the gutter 2 or fixture 1 is solved. After the snow has been removed automatically in this way, if the metal piece 23 covering the detached ear 22 of the rain gutter 2 is magnetically attached again to the magnet 12 of the fixture 1, it can be restored to its original state very easily. It is very convenient because it can restore the installed condition of the rain gutter.

Note that the ear receiving member 13 to which one ear portion 21 is attached
As mentioned above, the ear part 2 has high rigidity and hardly deforms elastically, so when a snow load is applied to the rain gutter 2, the ear part 2
1 will not fall out from the ear receiving member 13.
