Abstract

PURPOSE: To prevent overflow by fitting a heating element into a rain gutter, inclining and mounting a net body obviating the intrusion of ice and snow to a lower section in the rain gutter and forming a molten-water flowing section. CONSTITUTION: Heating means 2, by which heating wires are buried and pipes are interiorly finished and warm water or warm air is supplied, are interiorly finished into a rain gutter 1 in the longitudinal direction, and the external surface side of the rain gutter 1 is filled with a heat-insulating material, etc. A net body 6 is inclined and fixed to a lower section on the longitudinal one side in the rain gutter 1, and a molten-water flowing section 5, in which water can be passed and which inhibits the intrusion of ice and snow, is formed into the rain gutter 1. Accordingly, since snow intruding into the rain gutter is successively melted and flowed, the pressure of roof snow applied to the rain gutter is reduced, thus preventing the torsion and damage of the rain gutter.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rain gutter installed in the lower front part of the eaves, and is particularly applicable to a snowfall area.

[0002]

2. Description of the Related Art A conventional rain gutter is formed by using a thin iron plate or synthetic resin as a material, and is supported and fixed by a metal fitting provided at the eaves. The rain gutter receives rainwater flowing down the roof from the eaves, and the rain gutter circulates the rain gutter to drain the water from the upright pipe to the drain.

[0003]

The conventional rain gutter does not cause any particular problem in passing rainwater, but various problems occur when snow is accumulated on the roof in the winter in a snowfall region. .

That is, roof snow flows down so as to wrap around the eaves, enters the rain gutter, fills the rain gutter, and freezes. As a result, the snowmelt water that flows down cannot flow in the rain gutter, overflows, and falls directly from the gutter. Further, the overflowed snowmelt water forms icicles when the temperature drops, and the grown icicles fall due to the rise in temperature, which may cause an accident that may harm passersby.

On the other hand, since the snow filling the rain gutter is the tip of the roof snow that is trying to slide down, the pressure to slide down acts on the snow in the gutter and receives the pressure. The rain gutter is twisted and damaged, and it is forced to be repaired or replaced.

Therefore, the present invention prevents the snow that has entered the rain gutter from blocking the flow of the snowmelt water, prevents damage to the rain gutter due to the pressure of the snow, and further melts the roof snow. Also intends to provide a rain gutter that can be used.

[0007]

The present invention is characterized in that it has heat generating means for heating a rain gutter so that ice and snow in the rain gutter can be melted. In addition, a melt flow passage is formed which allows water to pass through the rain gutter and prevents ice and snow from entering.

[0008]

Since the present invention has the heat generating means for heating the rain gutter, the heated rain gutter functions to melt the snow in the rain gutter into water. Therefore, the inside of the rain gutter is filled to prevent the occurrence of snow and freezing of snow or water, which blocks the flow.

Further, since the snow in the rain gutter is sequentially melted and discharged as water to be drained, it has the effect of reducing the pressure of the snow on the rain gutter, which is slipping off. It also has the effect of melting and draining the snow from the tip of the roof snow.

Further, the molten water flow section that allows water to pass through but blocks the intrusion of ice and snow has a function of ensuring a running water channel without being blocked by ice and snow, and prevents overflow regardless of the melting action of ice and snow. Of.

An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 is a cross-sectional view showing an embodiment of a rain gutter of the present invention, in which a heat generating means 2 is internally provided in a meat portion of a rain gutter 1 in a longitudinal direction, and an insulating material 3 is provided on an outer surface side of the rain gutter 1. The inner surface side is filled with the heat insulating material 4.

As the heat generating means 2, it is conceivable that the heating wire 2A is embedded in the meat portion or the pipe 7 is internally provided to supply hot water or hot air 2B, and hot water and hot air are circulated.
The warm air may be circulated by using warm air generated by heating the interior of the house.

Further, the heat generating means 2 is not limited to one place in the meat portion of the rain gutter 1, but may be provided in several places in the length direction as required, and a heat insulating material or a heat insulating material is also used. It is optional.
Further, the portion through which the heat generating means 2 passes may be partially thick as shown in FIG.

FIG. 3 is a cross-sectional view showing an embodiment in which a melt flow section 5 which allows water to pass through and prevents ice and snow from entering the rain gutter 1 is provided. The net body 6 is tilted and fixed to the lower part to prevent solidified ice and snow from entering.

In FIG. 3, the molten water flow portion 5 is provided at the lower portion on the rear side, but it may be formed on the lower portion on the front side, or may be formed on the entire surface of the lower portion to form an upper / lower double structure. Further, the mesh of the net body 6 forming the melt flow section 5 can be appropriately selected. Even if some ice and snow enters the molten water flow section 5, it does not have to stop the flow of the snow melt water, and therefore, it is possible to classify with a relatively coarse grid.

[0016]

INDUSTRIAL APPLICABILITY As described above, according to the present invention, the roof snow that has entered the rain gutter is heated by the heat generating means to melt the snow so that the snow flows quickly. It exerts the effect of inhibiting the failure and preventing the obstacle due to the overflow.

Further, since the snow that has entered the rain gutter is melted and flowed sequentially, the pressure of the roof snow on the rain gutter is reduced, twisting and damage of the rain gutter can be prevented, and the falling snow can be sequentially dropped. As a result of melting, the snow-removing effect of the roof snow is also exerted as a result.

Further, by forming the molten water flow section in the rain gutter, even if the snow melting capacity cannot immediately respond to the amount of snow falling into the rain gutter, the occurrence of running obstacles in the rain gutter can be prevented, It has the effect of avoiding overflow from the rain gutter.
