Abstract

(57) [Summary] [Structure] An inner cylinder 11 is inserted from the inside of the room and an outer cylinder 12 is inserted from the outside of the room into a hole a formed so as to penetrate through a door A of the toilet or other room. Are integrated by screwing. Near the inner end of the inner cylinder 11 and the outer cylinder 12
Attach lenses 2 and 2 near the outer edge of the. Then, on the inner surface of the inner cylinder 11 between the two lenses 2 and 2, the light reflecting film 3 made of a resin film obtained by vapor deposition of aluminum.
Put on. [Effect] The light in the room reaches the outside of the room through both lenses 2 and 2, but while a part of the light passing through the inner lens 2 reaches the outer lens 2, the light is reflected on the inner surface of the inner cylinder 11. The light is reflected by the attached light reflection film 3, passes through the outer lens 2, and leaks to the outside. Therefore, the amount of light leaking to the outside of the room increases, and when viewed from the outside of the room, the amount of light reflected by the light reflecting film 3 looks bright.

Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention is a part attached to a hole formed through a toilet or other door of a room, and it is possible to confirm from outside the room whether the room has electricity by light leaking through the part. For example, it relates to the improvement of what was made possible to let people know that there was a person in the room.

[0002]

[Prior art]

 As a component of this type, conventionally, it is known that a cylindrical body is inserted into a hole formed so as to penetrate through a door of a toilet or other room, and lenses are attached to both sides of the cylindrical body. There is.

Then, this tubular body is inserted into a hole formed so as to penetrate through a door of a room such as a toilet, and light in the room leaks out through the lens from the hole of the tubular body of this component. Therefore, even when the door is closed, the light can be confirmed from outside the room. For example, it is possible to turn on electricity to the room and see that a person is inside.

[0004]

[Problems to be solved by the device]

 However, in the conventional case, the amount of light leaked to the outside is insufficient, and for example, there is a case where there is electricity in the room and people are in it, but it may be overlooked.

The present invention is intended to solve the above-mentioned drawbacks, and makes it possible to sufficiently check the light leaking from the room from outside even when the door is closed.

[0006]

[Means for Solving the Problems]

 In order to achieve the above object, in the present invention, a cylinder 1 is inserted into a hole a formed so as to penetrate a door A of a toilet or other room, and lenses 2 and 2 are provided on both sides of the cylinder 1. In the attached one, the light reflection film 3 is attached to the inner surface of the cylindrical body 1 between the lenses 2 and 2.

[0007]

[Action]

 In the product of the present invention, as in the conventional case, the cylindrical body 1 is inserted into the hole a formed so as to penetrate through the door A of the toilet or other room, and the room light is emitted through the hole of the cylindrical body 1. Even if the light leaks out through the windows 2 and 2, and the door is closed, the light can be confirmed from outside the room. For example, it is possible to know from the outside that there are people in the room. .

In this case, the light in the room reaches the outside of the room through both lenses 2 and 2, but while a part of the light passing through the inner lens 2 reaches the outer lens 2, The light-reflecting film 3 attached to the inner surface of the lens is reflected by the light-reflecting film 3, passes through the lens 2 on the outer side, and leaks to the outside. Therefore, the amount of light leaking out of the room is increased by that amount, and when viewed from outside the room, the amount of light reflected by the light reflecting film 3 located between the lenses 2 and 2 looks bright.

【Example】

 Embodiments of the present invention will be described with reference to the accompanying drawings.

In the embodiment, the inner cylinder 11 and the outer cylinder 12 have the cylindrical body 1 inserted into the hole a having a size of about 3 cm formed so as to penetrate through the door A of the toilet or other room. As an example, the inner cylinder 11 inserted into the hole a from the inside of the room and the outer cylinder 12 inserted into the hole a from the outside of the room are screwed together to form a unit. It is attached to hole a. In this case, collars 11a and 12a are formed at the ends of the inner cylinder 11 and the outer cylinder 12, respectively, so that when they are inserted into the hole a of the door A, these do not get into the depth of the hole a. There is. The inner cylinder 11 and the outer cylinder 12 can be made of resin such as ABS resin, for example.

Lenses 2 and 2 are mounted near the inner end of the inner cylinder 11 and near the outer end of the outer cylinder 12, respectively. Both lenses 2 and 2 are so-called plano-convex lenses, one surface of which is flat and the other surface of which is convex, and these are mounted so that the convex portions are on the outside, and the inner cylinder 11 is joined. Two lenses 2 and 2 are positioned on both sides of one cylindrical body 1 including the outer cylinder 12 and the outer cylinder 12. The lens 2 can be made of resin such as acrylic resin.

As described above, the tubular body 1 is inserted into the hole a attached so as to penetrate the door A of the toilet or other room. Then, the light reflecting film 3 is attached to the inner surface of the cylindrical body 1, and in the case of the embodiment, to the inner surface of the inner cylinder 11. The light reflection film 3 may be, for example, a resin film on which aluminum is vapor-deposited. By attaching this to the inner surface of the cylinder 1, the light reflection film 3 is attached to the inner surface of the cylinder 1. It can be

As an alternative to this, a case where a metal that reflects light is applied to the inner surface of the cylindrical body 1 and, in the case of the embodiment, the inner surface of the inner cylinder 11 to form a metal plating layer is cited. However, it is needless to say that the present invention is not limited to these cases, and the point is that the light reflection film 3 is formed on the inner surface of the cylindrical body 1.

The light in the room reaches the outside of the room through the lenses 2 and 2 located on both sides of the cylindrical body 1, while a part of the light passing through the inner lens 2 reaches the outer lens 2. Then, it hits the light-reflecting film 3 mounted on the inner surface of the inner cylinder 11, which is reflected by the light-reflecting film 3, passes through the outer lens 2 and leaks to the outside. Therefore, the amount of light leaking out of the room increases, and when viewed from outside the room, the amount of light reflected by the light reflecting film 3 located between the lenses 2 and 2 looks bright. 1 shows an embodiment In FIG. 1, the person marked IN (right side of the figure) is inside the room, and the person marked OUT (left side of the figure) is outside the room.

Although not shown, if minute pyramid-shaped prisms are regularly arranged in a flat portion which is the inner surface of the lens 2, the inside of the room is passed through the hole of the cylinder 1 from the outside of the room. It will not be completely visible when you look at it, which may be convenient.

[0016]

[Effect of device]

 According to the present invention, since the light in the room can be sufficiently confirmed from the outside through the present component mounted in the hole a formed so as to penetrate through the door A of the toilet or other room, the room can be sufficiently checked from the outside. It has the effect of turning on the electricity inside and not overlooking people inside it.
