Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drain cover of an angle-adjustable type used for a horizontal drain.

[0002]

2. Description of the Related Art Drains for draining rainwater are used on the roof of buildings such as buildings and condominiums and on the verandas on each floor. Well known is a so-called vertical drain, which penetrates through and discharges downward.

However, when there is a room directly below the floor, it is difficult to install a vertical drain, so in such a case, rainwater is discharged laterally through the standing wall. It is necessary to install a so-called horizontal drain.

FIG. 11 and FIG. 12 show an example of a conventional horizontal drainage drain. This type of horizontal drainage drain 1 includes a substantially horizontal tray-shaped water receiving container 2 and a rear portion of the water receiving container 2. The main body is a drain body 4 integrally formed with an upright vertical flange 3, and the drain body 4 comprises
By fixing the vertical flange 3 to the front surface of the standing wall 6 with the water receiving container 2 installed on the floor surface 5 such as a veranda,
It can be attached to a corner between the floor surface 5 and the standing wall 6.

Further, the vertical flange 3 of the drain body 4 is provided with a drainage port 7 projecting toward the rear standing wall 6 side, and the drainage port 7 penetrates the standing wall 6 substantially horizontally. A drain pipe 8 that bends downward is connected to the outside of the standing wall 6.

Further, the drain body 4 is provided with a horizontal cover portion 9 for covering the upper surface of the water receiving container 2 and a vertical cover portion 10 for covering the front surface of the vertical flange 3, and the side surface is substantially L-shaped. A drain cover 11 integrally formed into a shape is attached via a bolt or the like (not shown), and the drain cover 11 is formed with a plurality of slits 12 for introducing rainwater from the outside. .

Thus, the rainwater mainly collected on the floor 5 is
The drain cover 11 is introduced into the water receiving container 2 through the slits 12. At this time, foreign matter such as leaves and twigs is blocked by the drain cover 11, and only rainwater is discharged from the drainage port 7 through the drainage pipe 8. To be done.

[0008]

However, in such a horizontal drain 1, when the drain cover 11 is corroded and damaged due to long-term use, or when only the drain cover 11 disappears due to mischief or the like. In addition, it is necessary to re-install a new drain cover 11, but the same with respect to the horizontal drain 1 in which the drain body 4 and the drain cover 11 are installed in conformity with the standard in advance when constructing a building. Standard drain cover 11
Is very difficult to obtain, and the drain cover 11 that is generally manufactured for repair has only the one in which the horizontal cover portion 9 and the vertical cover portion 10 are arranged at right angles. Therefore, when the corners of the floor surface 5 and the standing wall 6 are not finished to form a right angle, the drain main body 4 mounted corresponding to this is
There is a problem in that there is a case in which the repair drain cover 11 cannot be mounted without a gap.

For example, as shown in FIG. 13, when the corners of the floor surface 5 and the standing wall 6 are bent in a circular arc,
When the vertical cover portion 10 of the drain cover 11 is attempted to be attached to the vertical flange 3 of the drain body 4, the horizontal cover portion 9 of the drain cover 11 is separated from the upper surface of the water receiving container 2 of the drain body 4 to form a gap. Also, when the floor surface 5 is formed with a slope so that rainwater can be smoothly guided, as shown in FIG. 14, the drain cover 1
1 side cover 9 and drain body 4 water receiver 2
There was a triangular gap between and.

Particularly, as shown in FIG. 15, a floor surface 5 and a standing wall 6 are provided.
When the corners of and are finished with an inclined surface having an inclination of about 45 °, the vertical flange 3 of the drain body 4 is formed along the inclined surface. When the horizontal cover portion 9 of the drain cover 11 is tried to be attached along the water receiving container 2 of the drain body 4, the gap between the vertical cover portion 10 of the drain cover 11 and the inclined surface is greatly opened, and the drain cover is opened. The function as 11 cannot be fulfilled at all.

Therefore, as described above, when the corners of the floor surface 5 and the standing wall 6 are not finished to form a right angle, the horizontal cover portion 9 and the vertical cover portion 10 are arranged at a right angle. I had to give up the drain cover 11 that was made up of the above, and I had no choice but to cover only the inlet of the drainage port 7 using a flat plate-like plate used for a vertical pulling drain. However, since the total opening area of the slits 12 that can be formed in the perforated plate is significantly smaller than that of the drain cover 11, there is a problem that the perforated plate is likely to be clogged with foreign matter such as fallen leaves or twigs. there were.

In view of the above-mentioned circumstances, the present invention provides a drain main body mounted correspondingly even when the corners of the floor surface and the standing wall are not finished to form a right angle. The purpose of the present invention is to provide a drain cover that can be mounted without gaps.

[0013]

DISCLOSURE OF THE INVENTION The present invention is a horizontal pulling device installed at a corner between a floor surface and a standing wall so that rainwater collected on the floor surface can be discharged sideways through the standing wall. A drain cover used for a drain, in which a horizontal cover part having a plurality of slits for introducing rainwater and a vertical cover part are hinged to each other, and both cover parts are tilted and tilt angles are set. It is characterized in that it is configured to be self-holding.

With this configuration, when the corners of the floor surface and the standing wall are not finished to form a right angle, the sideways cover and It is possible to adjust the vertical cover portion to an arbitrary angle and mount it.

Further, each of the horizontal cover portion and the vertical cover portion has a pair of outer frames arranged on both sides in the width direction, and an inner handle integrally provided between the outer frames to form a plurality of slits. The outer frames of the horizontal cover portion and the vertical cover portion can be pivotally attached to each other via a spring pin.

Further, it is preferable that the corner portion formed by the lower surface of the lateral cover portion and the rear surface of the vertical cover portion is curved so that the side surface forms an arc.

The spring pins 21 are formed in such a manner as to face each other along the axis line x of the spring pins 21, and do not hinder the tilting of the lateral cover portion 15 and the vertical cover portion 16.

However, the design of the inner shafts 19 and 20 is substantially arbitrary, and it is not always necessary to have a structure composed of the rod members 24 and 25 and the bridges 26 and 27 as shown in the drawing, and the slits 14 having a plurality of threads 14 Various designs can be adopted as long as they are formed.

The inner handle 20 of the vertically oriented cover portion 16 is also provided.
As shown in FIGS. 6 and 7, at the appropriate position on the back surface of the slender member, a long and slender member 28 made of stainless steel having high elasticity extending in the width direction of the vertical cover is provided with a bolt 29 and a nut 3.
0 is attached via a fastener 31 and a guide member 32 that holds a nut 30 of the fastener 31 slidably in the vertical direction. The bolt 29 is tightened to attach the nut 30 to the inner surface of the guide member 32. The elongated member 28 can be fixed to the guide member 32 by pressure contact, and the drain cover 13 is provided in the existing laterally drawn drain 1.
7 is attached to the drain body 4, the elongated member 28 is bent into a U shape as shown by a chain double-dashed line in FIG.
The drain cover 13 can be attached to the drain body 4 by the elastic force of 8 for restoring.

Thus, according to the drain cover 13 of the present embodiment as described above, the horizontal cover portion 15 and the vertical cover portion 16 can be tilted like a hinge, and the tilt angle is a spring pin. Since it is self-held by the frictional resistance generated by the spring action of 21, the drain attached corresponding to the case where the corners of the floor surface 5 and the standing wall 6 are not finished at a right angle The horizontal cover portion 15 and the vertical cover portion 16 can be adjusted and attached to the main body 4 at any angle.

Therefore, for example, as shown in FIG. 8, when the corners of the floor surface 5 and the standing wall 6 are bent in an arc, the horizontal cover portion 15 and the vertical cover portion of the drain cover 13 are bent. When 16 and 16 are opened slightly more than 90 °, the upper surface of the water receiving container 2 is almost completely covered by the lateral cover portion 15 and the front surface of the vertically oriented flange 3 is substantially completely covered by the vertically oriented cover portion 16. On the drain cover 1
3 can be mounted.

At this time, as shown in the present embodiment, if the corners formed by the lower surface of the lateral cover portion 15 and the back surface of the vertical cover portion 16 are curved so that the side surface forms an arc, The corners are well accommodated in the corners between the floor surface 5 and the standing wall 6, and the gap can be prevented more reliably.

Further, as shown in FIG. 9, when the floor surface 5 is formed with a slope so that rainwater can be smoothly guided, the horizontal cover portion 15 and the vertical cover portion 16 of the drain cover 13 are provided. Is slightly closed from 90 °, the upper surface of the water receiving container 2 is substantially completely covered by the horizontal cover portion 15 and the front surface of the vertical flange 3 is substantially completely covered by the vertical cover portion 16.
