Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a drainage device.

[0002]

2. Description of the Related Art For example, in a general house, a step is provided between an entrance door and an outside doorway portion of a door installed on the front side of the entrance door to prevent rainwater from entering indoors. However, in such a house, when using a wheelchair or the like, the step becomes an obstacle.

[0003] Therefore, there is provided a so-called barrier-free type house in which the above-mentioned steps are eliminated or the steps are slightly reduced.

[0004]

As described above, eliminating the steps at the entrance is convenient for passing through a wheelchair or the like.
When the rainwater sprinkles, naturally the rainwater easily enters the house. However, there is no particular facility for preventing rainwater from entering the house having no step.

Therefore, an object of the present invention is to provide a drainage device that can solve the above-mentioned problems.

[0006]

Means for solving the problems according to the present invention are provided in a house having no steps between the outside and inside entrances through a door, and are provided along the width direction of the door opening. The main body is embedded in the outside doorway of the door, and the main body is formed in a gutter shape with a bottom plate and a side plate rising from the bottom plate, and the upper part of the main body has substantially the same height as the outside doorway portion of the door. An open portion is formed, and a drain hole for connecting a drain pipe for draining to a drain facility provided at another location is formed on the end side of the bottom plate.

[0007] According to the above structure, the rainwater that has sprinkled on the outside entrance and exit of the door flows into the main body from the opening, drains from the drain hole to the drainage facility provided at another location. Is done.

Further, a safety member having a cover plate for dividing the open portion is provided by covering a central portion of the open portion of the main body in a direction along the side plate, and the cover plate is detachably provided on the main body. ing.

According to this configuration, when the safety member is mounted on the main body, the front and rear width of the opening is reduced by the cover plate, so that the heel of the shoe is prevented from being fitted into the main body.

[0010]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A drainage device according to an embodiment of the present invention will be described below with reference to FIGS.

As shown in FIGS. 1 and 3, on the outside of an entrance door 2 of a house 1, an outside doorway portion 3 of a door made of a concrete foundation S1 and a mortar S2 finished on the surface side of the foundation is provided. The entrance door 2 and the outside entrance / exit portion (consisting of the concrete of the foundation S1 and the finished mortar S2) 3 have slight steps corresponding to the thickness of the door sash 4.

The drainage device 5 according to the embodiment of the present invention is embedded in the outside doorway portion 3 of the door along the width direction of the door opening 6. As shown in FIG. 2, in the drainage device 5, the main body 7 includes a bottom plate 8 and a pair of side plates 10 that stand upright at the front and rear positions from the bottom plate 8. The intake opening 11 is set at the same height, and is formed in a gutter shape as a whole.

The upper end of each side plate 10 is bent into an L-shape to form a holding portion 12, and covers 13 are provided at both left and right ends of the main body 7 to cover open ends on both sides of the main body 7. . At one end of the bottom plate 8, a drain pipe 15 for draining to a drainage facility 14 provided at another place (for example, a drainage groove provided at the side of the outside entrance / exit portion 3 of the door) 14 is provided via an installation plate 16. A drain hole 17 is formed for connection.

Further, the central portion of the opening 11 is connected to the side plate 1.
A safety member 20 having a cover plate 18 that is divided into front and rear by covering in a direction along 0 is provided.
Reference numeral 0 denotes an I-shaped cross section, and the installation portion 21 below the safety member 20 is detachably mounted on the bottom plate 8 of the main body 7 via the support plate member 22.

Next, the case where the drainage device 5 is installed will be described. When the concrete of the foundation S1 of the outside entrance part 3 of the door is poured, the drainage pipe 15 is embedded and one end of the drainage pipe 15 is inserted. Is projected from the foundation S1, and the other end is connected to another drainage facility 14.

Next, when the finished mortar S2 is cast, the mortar S2 with the cover 13 attached to the open portions 11 on both sides of the main body 7 is integrally formed, and the installation portion 21 is installed on the bottom plate 8 to secure the safety member. 20 is mounted on the main body 7.

In this way, when the rainwater R is sprayed on the outside entrance / exit portion 3 of the door, the outside entrance / exit portion 3 of the door is not affected.
Rain water R flows into the main body 7 from the open portion 11 of the main body 7, passes through the drain hole 17 through the drain pipe 15,
4 to prevent rainwater R from entering the doorway inside the door.

When a person passes, the open portion 11 of the main body 7 is divided into front and rear portions by the cover plate 18 of the safety member 20 so that the front and rear width of the open portion 11 is reduced. As described above, the heel portion of the shoe is safe from being fitted, and there is no concern that the wheel of the wheelchair is fitted.

As described above, according to the drainage device 5 of the embodiment of the present invention, the rainwater R at the outside entrance 3 of the door is
Since the water is drained to another drainage facility 14, even in a house where no step is provided between the entrance door 2 and the outside entrance 3 of the door, the rainwater R enters the house from under the entrance door 2. Can be prevented.

In the above embodiment, the drain holes 17 are formed only at one end of the bottom plate 8, but the present invention is not limited to this, and the drain holes 17 are formed at both end portions of the bottom plate 8.
Another drainage facility 14 may be provided on both sides of the outside entrance / exit portion 3 of the door, and each drainage hole 17 and each drainage facility 14 may be connected by the drainage pipe 15.

In the above-described embodiment, the body 7 and the cover 13 are integrally formed when the finished mortar S2 is cast. However, the present invention is not limited to this. As a post-installation step, the finished mortar S2 may be suspended in a groove shape as required, and the drainage hole 17 may be connected to the drainage pipe 15 for installation.

[0022]

As is apparent from the above description, the present invention is characterized in that the main body embedded along the width direction of the door opening at the outside entrance of the door of the house has a bottom plate and a side plate rising from the bottom plate. The drain is drained to a drainage facility located elsewhere on the end of the bottom plate, with the upper part of the main body being an open part with almost the same height as the surface of the outside doorway of the door. Drain holes for connecting pipes are formed, so rainwater that has been sprayed on the outside entrance and exit of the door flows into the main body from the open part, passed through the drain pipe from the drain hole, and provided in another place. Even in a house that is drained toward the drainage facility and does not have a step between the inside and outside entrances of the door, it is possible to prevent rainwater or the like from entering the house from under the door.
