BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a draining device which is provided at a portion projecting from an outer wall surface of a building such as a bay window, and which prevents the lower outer wall surface from freezing or becoming dirty due to rain or the like.

[0002]

2. Description of the Related Art In recent years, in order to make the interior space of a building look wider and to make daylight more advantageous, for example, as shown in FIG. A large number of bay windows 2 formed by projecting to the inside are becoming visible.

By the way, in such a bay window 2,
When it rains, rainwater etc. that has fallen on the top plate 5 of the bay window 2 flows down from the top plate 5 into the entry corner region 4 between the side plate 3 and the outer wall surface 1, and further from the lower end of the entry corner region 4 to the outer wall surface. It flows down 1 and flows downward.

However, in such a structure of the bay window 2, rainwater or the like flowing on the outer wall surface 1 may be frozen in the winter or cold regions. When rainwater or the like freezes, there is a problem that frost damage such as cracking of the outer wall surface 1 is likely to occur. In addition, there is a problem that the outer wall surface 1 is soiled or discolored by rainwater flowing along the outer wall surface 1 to impair its aesthetic appearance.

The present invention has been made in view of the above problems, and an object thereof is to provide a building member, such as a bay window or a sash frame, which is provided on the outer wall of a building so as to project from the outer wall.
Another object of the present invention is to provide a draining tool that can prevent freezing damage and stains on the outer wall surface caused by rainwater and the like.

[0006]

In order to achieve the above-mentioned object, a drainer according to the invention of claim 1 is a back plate,
A water receiving portion that extends forward from the back plate and has a water receiving surface that is an inclined surface whose upper surface is inclined downward, and one side edge portion of the back plate and the water receiving portion. And a mounting portion that is provided on the side of the water receiving portion opposite to the side on which the side plate is disposed and that has a mounting surface. According to a second aspect of the present invention, in the first aspect, the mounting surface of the mounting portion is formed at a position higher than the water receiving surface of the water receiving portion.

A drainer according to a third aspect of the present invention is a water drainer having a mounting portion having a mounting surface, and a water receiving surface which is provided continuously to the mounting portion and which extends downwardly and obliquely forward from an upper end side thereof. The water receiving section is characterized in that the upper end position of the water receiving section is arranged below the upper end position of the mounting section. The water drainer according to the invention of claim 4 includes a mounting portion having a mounting surface, and a water receiving portion which is provided continuously to the mounting portion and has a water receiving surface which extends downwardly and obliquely forward from an upper end side thereof. A rear surface portion that hangs from at least a part of the mounting surface-side end portion of the mounting portion and the water receiving portion and that faces the mounting surface, the rear surface portion being below the upper end side. It is characterized in that it has a notch provided continuously at the position in the direction of the surface to be attached.

[0008]

According to the invention of claim 1, the mounting surface of the mounting portion is brought into contact with the side wall outer wall surface side of the bottom surface of the projecting member such as the bayonet member, and the rear surface of the rear plate is outside. By abutting against the wall surface, rainwater that flows down the entry corner area between the side plate of the projecting part such as the bay window and the outer wall surface falls on the water receiving plate of the water receiving part, and flows down forward along the slope of the inclined surface. It falls downward from the edge of the water receiving plate. Therefore, since the water receiving plate is arranged in front of the outer wall surface, rainwater that has fallen from the leading edge of the water receiving plate will fall directly onto the ground without propagating down the outer wall surface below the protruding portion such as the bay window. become.

According to the second aspect of the invention, since the mounting surface of the mounting portion is made higher than the inclined surface, the rainwater that has run down on the water receiving plate of the water receiving portion when these are formed flush with each other. It is almost prevented that, due to the capillary phenomenon, etc. enter between the bottom surface of the bay window projection and the mounting surface or between the side plate of the bay window projection and the side edge of the back plate and fall along the outer wall surface as it is. .

The place where the drainer is attached is an inside corner area formed between the side surface of the sash frame or the like attached to the opening provided on the outer wall surface and the outer wall surface, and forms the sash frame and the outer wall surface. Even when a joint is formed with the outer wall finishing material, the upper end position of the water receiving part is located below the upper end position of the mounting part, so that the mounting surface of the mounting part is on the bottom of the sash frame. Even if the water drainer is moved to the sash frame side as necessary while being in contact with the sash frame, the water catcher can adjust the attachment position of the water drainer without hitting the sash frame. Therefore, it is possible to cope with a difference in joint width due to an error or the like, and the drainer can be reliably attached to an appropriate attachment position. The action as a draining tool is the same as that of the first aspect of the invention.

In the invention according to claim 4, for example,
The place where the drainer is attached is an inside corner area formed between the side surface of the sash frame or the like attached to the opening provided on the outer wall surface and the outer wall surface, and forms the sash frame and the outer wall surface. Even if a joint is formed between the outer wall finishing material and the outer wall finishing material, the back portion of the water drainer has a notch, so that the outer wall finishing material provided below the joint and the back portion do not collide with each other. Can be prevented. Therefore, at a suitable mounting position, the joint and the back portion can be brought into close contact with each other to mount the drainer. The action as a draining tool is the same as that of the first aspect of the invention.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT A preferred embodiment of the present invention will be described in detail below with reference to the drawings.

(Embodiment 1) FIG. 1 is a perspective view showing a drainer according to Embodiment 1, and reference numeral 10 in FIG. 1 is a drainer. The water drainer 10 includes a back plate 11, a water receiving plate 12 that is a water receiving portion that extends forward from a lower end of the back plate 11, and one side edge of the back plate 11 and the water receiving plate 12. On the side plate 13 provided on the side of the water receiving plate 12 and on the side of the water receiving plate 12 opposite to the side plate 13 provided on the side plate 13.
It is made of metal, synthetic resin, or the like, and is composed of a mounting plate 14 that is a mounting portion that extends from 1 to the side thereof.

As shown in FIG. 2, the back plate 11 has a rectangular shape whose back surface (back surface) is in contact with the outer wall surface 1.
If necessary, holes (not shown) may be formed in the rear plate 11 in advance, and the rear plate 11 may be fixed to the outer wall surface 1 by nailing or screwing using the holes.

The water receiving plate 12 is located in front of the back plate 11,
That is, it has a rectangular shape extending forward with respect to the outer wall surface 1, and the front end side is inclined downward with respect to the direction orthogonal to the back plate 11 as a whole. Therefore, the upper surface of the water receiving plate 12 is an inclined surface 12a that inclines downward. It should be noted that the inclination angle of the inclined surface 12a can be set arbitrarily without any particular limitation, but if it is too large, there is a risk that rainwater that falls along this will be transmitted to the outer wall surface 1 as described later. Yes, on the other hand,
If it is too small, rainwater may stay on the inclined surface 12a.
About 60 ° is suitable. Also, in this example,
As shown in FIG. 1, the water receiving plate 12 is formed such that one side portion thereof extends laterally from the back plate 11.

The side plate 13 has a triangular shape and is continuously provided on the same side edges of the back plate 11 and the water receiving plate 12. By connecting the back plate 11 and the water receiving plate 12 to each other, The purpose is to maintain the angle between them and to increase the strength of the draining tool 10 as a whole.

The mounting plate 14 is fixed to the water receiving plate 12 on the side opposite to the side plate 13, that is, on the side of the water receiving plate 12 extending from the back plate 11 by screwing or welding. The bottom surface is formed to have an inclination angle corresponding to the inclination angle of the inclined surface 12a so that its upper surface (mounting surface 14a) is substantially horizontal, that is, substantially coincides with the direction orthogonal to the back plate 11. The mounting plate 14 is connected to a hole (not shown) formed in the water receiving plate 12 so that the mounting hole 15,
The mounting plate 14 is attached and fixed to the bottom surface of the portion where the mounting surface 14a projects from the outer wall surface 1 such as a bay window by nailing or screwing.

In order to attach the water draining tool 10 having such a structure to a bay window, for example, as shown in FIG.
With the outer wall surface 1 and the mounting surface 1 of the mounting plate 14
4a is brought into contact with the side end portion of the bottom surface of the bay window 2, and in that state, nailing or screwing is performed using the mounting hole 15.

When the draining tool 10 is attached to the bay window 1 in this manner, when rain or the like falls, rain water or the like that flows down the entry corner region 4 between the side plate 3 of the bay window 2 and the outer wall surface 1 will be received by the water catcher. The water is received on the plate 12, guided further forward along the inclination of the inclined surface 12 a, and falls downward from the tip edge of the water receiving plate 12. Therefore, since the water receiving plate 12 is arranged in front of the outer wall surface 1, rainwater or the like that has fallen from the front edge of the water receiving plate 12 does not directly reach the outer wall surface below the bay window 2 and directly reaches the ground or the like. As a result, it is possible to prevent freezing and stains on the outer wall surface 1 caused by rainwater or the like traveling along the outer wall surface 1 in winter or even in a building where the bay window 2 is installed in a cold region. it can.

Further, since the mounting plate 14 is mounted and fixed on the water receiving plate 12, the mounting surface 14a has the water receiving plate 12
Therefore, when they are formed flush with each other, the rainwater that has flowed down on the water receiving plate 12 will fall between the bottom surface of the bay window 2 and the mounting surface due to the capillary phenomenon. Or between the side plate 3 of the bay window 2 and the side edge of the back plate 11 and then, as it is, the outer wall surface 1
There is almost no chance that it will fall down along the way, which also eliminates the worry of freezing and dirt.

Although the mounting plate 14 is mounted on the water receiving plate 12 in the above embodiment, the water receiving plate is formed to have the same width as the back plate 11, and the mounting plate is attached to the side edge of the water receiving plate. It may be attached by welding or the like, and in that case, the upper surface (mounting surface) of the mounting plate may be formed so as to be substantially horizontal without being made higher than the inclined surface of the water receiving plate. Further, the water receiving plate 12 and the mounting plate 14 are integrally formed, and only a portion corresponding to the water receiving plate 12, that is, a portion corresponding to the width of the back plate 11 is cut so as to be inclined downward to form an inclined surface. Good.

It has been extended. Further, as shown in FIG. 4, the boundary between the front surface of the back plate 21 and the inclined surface 22a of the water receiving plate 22 is inclined in the same direction as the inclined surface 22a and has an extremely acute angle as compared with the inclined surface 22a. Slope 2
6 is formed, whereby the drainer 20 is attached to the outer wall surface, and when rainwater or the like is transmitted to the drainer 20, the rainwater or the like will reach the sloped portion 26.
As it travels down, it flows down onto the inclined surface 22a without staying there, and then flows down along the inclined surface 22a.

As shown in FIG. 4, the side plate 23 has its upper end edge formed substantially parallel to the inclined surface 22a of the water receiving plate 22, and its front portion is formed to have a curvature so as to be rapidly inclined downward. Rainwater and the like that have fallen onto the side plate 23 are also guided to the front of the side plate 23 and further flow downward from the tip of the rainwater.

Furthermore, on the bottom side of the water receiving plate 22, as shown in FIG.
As shown by the middle broken line, a recess 27 is formed corresponding to almost the entire surface of the water receiving plate 22, whereby the drainer 2
When 0 is attached to the outer wall surface and rainwater or the like that travels along the outer wall surface when raining falls around the drainer 20 and reaches the bottom surface of the drainer plate 22, the rainwater or the like is guided to the recess 27 and falls. As a result, it does not stay here and falls downward.

FIG. 1 shows the drainer 20 of this kind.
Similarly to the water draining tool 10 shown in FIG. 2, when rain or the like falls, the rainwater that flows down in the entry corner region between the side plate of the bay window and the outer wall surface is received on the water receiving plate 22, and further along the slope of the inclined surface 22a. The rainwater is guided forward and falls downward from the edge of the water receiving plate 22. Therefore, since the water receiving plate 22 is arranged in front of the outer wall surface, it is possible to drop rainwater dropped from the tip edge of the water receiving plate 22 directly onto the ground or the like without passing through the outer wall surface below the bay window. In this way, it is possible to prevent freezing and stains on the outer wall surface caused by rainwater and the like traveling along the outer wall surface 1 in winter or even in the case where the building provided with the bay window is constructed in a cold region. You can
