Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an embedded wall-mounted outlet for mounting in a plug so that the plug does not project from the wall when the plug is inserted.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 10, an embedded outlet A is provided on a wall surface in a room or the like, and is used to quote the power difference of electric appliances in a room.

[0003] Such an embedded outlet A is provided approximately at the height from the floor. 300 on the floor in ordinary rooms
mm, and in a Japanese-style room, it is mounted at a height of 150 mm. In a parking lot or a place where water is used, the height is set to 1000 mm.

As shown in FIG. 10 (a), the embedded outlet A is provided so that the connection port for inserting the plug B is flush with the embedded wall surface F. for that reason,
As shown in FIG. 10B, the plug B is connected so as to project substantially perpendicularly to the wall surface.

[0005] The embedded outlet A may be mounted by floor embedding other than wall embedding.
An outlet is attached to a concrete floor mainly for offices and offices, desk lamps and other electric power quotes from the floor, and is called a floor outlet.

The mounting location varies depending on the purpose and size of the room, but if the size is relatively large in a general office room or the like, the power is generally reduced so that various layout changes can be made without any inconvenience. It is laid. In some cases, it is laid in a part of a room such as a showroom or a lower part of a counter.

Generally, in a general office or a room similar thereto, two outlets are evenly embedded in the inner wall at a ratio of one to a floor area of 20 to 30 cm ² . In a Japanese-style room of a general house, one room is provided for every three quires.

In the equipment machine room and the shaft,
There is an outlet for maintenance and one in a separate room.
Various considerations have been given to the arrangement of outlets, such as arranging more outlets.

[0009]

However, in a conventional wall-mounted outlet, generally, as shown in FIG.
Since the plug insertion port is provided so as to be flush with the embedded wall, when the plug is inevitably connected, it is connected as if it protruded vertically to the embedded wall of the embedded outlet It will be.

[0010] The wall-embedded outlet can be used in a case where a plug is inserted into the wall-embedded outlet each time an electric appliance or the like is used, or a case where the plug is always inserted.

[0011] The case where the plug is always inserted may be, for example, an ordinary household at the time of using an electric appliance such as an electric refrigerator or an electric pot, or a radio or television. Even in general offices, various O such as computers, copiers, word processors, etc.
The device A is normally used with a plug inserted.

When the plug is inserted into the connection port of the wall-mounted outlet as described above, since the plug protrudes from the embedded wall as described above, the plug protrudes and hinders the back of an electric appliance or the like. The side cannot be pressed perfectly against the wall.

Further, since the cord is often taken out from the rear side of the electric appliances, the plug connection is inevitably made on the rear side of these electric appliances. Therefore, when the plug is always used in a state of being connected to the outlet, it is easy to neglect to clean the plug connection part without being aware of the rear side of the electric appliances. If this state continues for a long time, dust C accumulates on the connection portion of plug B with embedded outlet A as shown in FIG. Such accumulated dust C sometimes carbonizes for a long time and may cause a fire.

An object of the present invention is to prevent a plug connected from an embedded wall from projecting when the plug is inserted into a wall embedded outlet.

The above and other objects and novel features of the present invention will become apparent from the description of the present specification and the accompanying drawings.

[0016]

SUMMARY OF THE INVENTION Among the inventions disclosed in the present application, the outline of a representative one will be briefly described.
It is as follows.

That is, in the present invention, a plug connection port is provided in an outlet box of a wall-embedded outlet to be embedded and mounted on a wall so that the plug does not protrude from the wall when the plug is connected.

The connection port of the plug may be provided obliquely with respect to the embedding wall surface, and the depth of the outlet box may be set so that the plug does not protrude from the embedding wall surface when the plug is obliquely connected in the outlet box. By providing the connection port at an angle, the depth of the outlet box can be reduced.

However, when the outlet box can be formed deep, the depth of the outlet box can be set to be equal to or greater than the length of the plug, and the connection port of the plug can be provided facing the embedding wall face. is there.

In order to form the connection port obliquely with respect to the embedded wall surface, it is preferable that the plug can be inserted obliquely upward. Further, it is also possible to provide a connection port so that plugs can be inserted obliquely laterally and diagonally downward.

However, considering that the wall-embedded outlet is usually provided on a wall surface slightly above the floor, it is preferable to provide the connection port so that the plug is inserted obliquely upward. This is because by inserting the plug obliquely upward, dust is less likely to accumulate, and the plug can be connected while checking the connection port.

In the configuration provided diagonally laterally and diagonally downward, dust easily accumulates at the plug connection portion.

Further, the front opening surface of the embedded outlet box is covered with a lid provided with a plug insertion hole, so that dust accumulation at the plug connection portion and oil adhesion to a kitchen or the like can be further prevented. I do not care.

[0024]

Embodiments of the present invention will be described below in detail with reference to the drawings.

(Embodiment 1) As shown in FIG. 1, a wall-embedded outlet 10 used in an embodiment of the present invention is configured to be embedded under a wall, and is connected to the inside of a rectangular outlet box 20. A mouth 30 is provided.

In the present embodiment, such an outlet box 20 is manufactured by resin molding like a conventional product, and is configured as two ports provided with two connection ports 30. The number of the connection ports 30 does not need to be limited to two, and may be three or more or one.

The connection port mounting surface 31 in the outlet box 20 provided with the connection port 30 is provided obliquely at an angle θ with respect to the embedding wall F as shown in FIG. Such a state is shown in a perspective view in FIG. The angle θ is set so that when the plug 40 is connected to the connection port 30, the plug 40 can be stored without protruding from the outlet box 20.

The angle θ can be set to various angles within the range of 0 to 90 degrees. However, as the angle θ is increased, the connection port mounting surface 31 approaches perpendicularly to the embedding wall F, and as in the conventional case, the lower part of the room When the wall-embedded outlet 10 is mounted at a height of about 200 mm above the floor, the connection port 30 is difficult to see, and it is difficult to insert the plug 40. Therefore, θ may be set to such an extent that the connection port 30 can be confirmed at the time of insertion.

When the mounting position of the wall-embedded outlet 10 is set higher than the position of the human eye, the connection of the plug 40 is facilitated by increasing the angle θ. For example, when mounting above a wall surface, a configuration in which the angle θ is increased may be used.

On the other hand, as the angle θ increases, the plug 40 connected to the connection port 30
Therefore, the connection can be made in a state of being laid down in a more parallel state, so that the depth a (embedding depth) of the outlet box 20 can be reduced.

Therefore, in the present embodiment, as shown in FIGS. 1 and 2, the connection port 30 can be clearly seen even when the connection port 30 is provided at a position below the indoor wall surface, and the angle of the connection port 30 is within a range in which the connection of the plug 40 can be easily performed. θ is set.

In this way, when the wall-embedded outlet 10 having the above configuration is mounted on the wall surface F, the connection port mounting surface 31 faces obliquely downward. for that reason,
When the plug 40 is connected to the connection port 30, as shown in FIG. 1, the plug 40 is connected such that the cord 41 hangs downward. In this state, the connection port mounting surface 3
Since 1 covers the plug connection portion, dust is less likely to accumulate in the plug connection portion in combination with the fact that the plug connection portion is provided inside the outlet box 20.

Further, since the cords 41 of the electric appliances are often taken out from a lower position such as the bottom on the back side of the electric appliances, the plugs 40 of the cords 41 are removed.
Is connected to the wall-embedded outlet 10 having the above-described configuration, as shown in FIG. 1, the cord 41 naturally hangs down, and unreasonable bending does not occur at the base of the cord 41 and the plug 40.

That is, since the plug 40 is not connected so as to protrude perpendicularly to the embedding wall F, unlike the conventional case (see FIG. 10B), the plug 40
And the base of the cord 41 do not bend at a steep angle,
Deterioration of the base of the cord 41 can be prevented.

In this embodiment, as shown in FIG. 1, the two connection ports 30a (30) and 30b (30) are provided with steps. Therefore, in the present embodiment, the lower connection port 30b of the two connection ports 30 is provided slightly behind the outlet box 20 than the upper connection port 30a.

By providing a step between the upper and lower connection ports 30a and 30b in this way, even if the plug 40 is connected to the upper connection port 30a and the lower connection port 30b at the same time, no collision occurs.

In the present embodiment, the upper connection port 30
The connection port mounting surface 31 of a and the connection port mounting surface 31 of the lower connection port 30b are both set to be inclined at the same angle θ with respect to the embedded wall surface F.

Further, in the present embodiment, a lid 50 is attached to the opening side surface of the outlet box 20. The lid 50 is also the outlet box 20
It is manufactured by resin molding in the same manner as described above.

The lid 50 is formed in a substantially rectangular shape and has a size capable of covering the rectangular opening of the outlet box 20, and a hole 51 for inserting a bolt is provided at the upper and lower central position. A bolt screwing portion 21 is also provided at the upper and lower center of the outlet box 20 so as to correspond to the hole 51 of the lid 50. Outlet box 20
Can be provided by screwing after embedding and mounting below the embedding wall surface F.

Further, as shown in FIGS. 1 and 3, a plug insertion hole 60 is formed in the lid 50.
Two connection ports 30 are provided vertically above and below the two connection ports 30. In this embodiment, the plug insertion hole 60 is formed in a rectangular opening, and its size and opening position are set so that the plug 40 can be easily inserted.

In this embodiment, the plug insertion hole 60 is formed as an opening without a lid.
As shown in (a), an inner lid 61 that opens only inside the outlet box 20 may be provided. By pushing the end of the plug 40 inside the outlet box 20 while keeping the tip of the plug 40 in contact with the inner lid 61, the inner lid 61 is pushed up and the plug 40 may be inserted into the connection port 30 as it is. In the connection state, FIG.
As shown in (2), the inner lid 61 is supported by the plug 40 and does not come down, but when the plug 40 is pulled out, the inner lid 61 goes down and the opening of the plug insertion hole 60 is closed. The inner lid 61 may be attached to the back side of the lid 50 with a hinge 62.

In the above embodiment, the upper and lower connection ports 30a and 30b are configured such that the respective connection port mounting surfaces 31 have the same angle θ with respect to the buried wall F. 31 may be different from each other.

Further, as shown in FIG. 5, the connection port mounting surface 31 may be formed on a uniform slope without providing a step. That is, the inside of the outlet box 20 is formed such that the connection port mounting surface 31 is uniformly obliquely downwardly directed along the up-down direction, and the connection port 30 is formed on the diagonal connection port mounting surface 31 vertically. It may be provided.

In such a case, the lid 50 provided with the plug insertion hole 60 as described above, or the inner lid 61 is also provided.
May be provided with the lid 50 provided in the plug insertion hole 60.

In the above description, the connection ports 30a, 30
Although b is provided with a step, each of the connection ports 30a and 30b may be provided at the same height as shown in the perspective view of FIG.

In the above embodiment, the lid 50 is provided, but a configuration without the lid 50 may be used. If the floor outlet is open on the floor without opening the opening of the floor outlet, it may be dangerous to stumble or drop small items. There are many cases where the portion is hidden on the back side of the electric appliance, and a configuration without a lid may be sufficient.

Even when the lid 50 is provided, if the surface of the lid 50 is provided so as to be flush with the embedding wall F, the rear side of an electric appliance or furniture can be arranged in close contact with the wall. .
