Abstract

PROBLEM TO BE SOLVED: To make the visualization of a lightening state easy in the room by clogging a hole formed by piercing through the room inside and room outside of a door with a light transmission body, and connecting the light transmission body in use of an optical fiber cable. SOLUTION: The body 12 of a light transmission member 2 is fitted in a hole formed on a door 1 having no window such as e.g. a toilet from the outside 11 of a room. The body 21 has an optical fiber cable 3 connected to a lenslike light transmission body 22 formed at its base end in its core part, and is provided with a male screw at its core tip end. Next, from the room inside 12, the female screw of a lid member 25 is screwed to the male screw of the core tip end of the body 21 for connecting the tip end of the cable 3 to the lenslike light transmission body 26 of the lid 25. During the use of a toilet, as a light in the room is transmitted from the room inside 12 to the room outside via the member 2, the light is transmitted to the light transmission 22 without being attenuated by the cable 3, resulting in a sufficient visualization of the light at the front of the door 1 even when the member 2 is disposed at the proximity of the upper and lower ends of the door 1. In this way, the presence and absence of lightening in the room inside can be visualized distinctly from the room outside even in a dark place, as a result, electric wiring or the like is not needed, and construction can be simplified.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] The present invention relates to a toilet and the like,
The present invention relates to a door such as a hinged door or a sliding door without a window.

[0002]

2. Description of the Related Art In a conventional door such as a toilet, which has no window, such as a hinged door or a sliding door, as a means for indicating whether or not the room is in use, a key such as a thumb turn or the like is locked from the room. In general, a color such as red is displayed near the handle on the outdoor side, but the display is difficult to see at night or in a dark place, which is inconvenient.

In some cases, a light bulb or the like is attached near a switch button of an electric light so that when the room is turned on, the light bulb is also turned on at the same time. You can tell whether the room is lit at night or in a dark place. If the unit breaks down, there is a problem that the lighting in the room cannot be recognized.

Therefore, as shown in FIG. 4, an opening 50 penetrating through a door 51 has conventionally been used so that the lighting state of the room can be directly viewed with a simple structure without wiring or other work.
And a transparent body 5 made of, for example, a template glass or the like.
2 is widely known and practiced.

However, when the transparent body 52 is fitted at a high position or when viewed from a low position such as a child, the indoor side 62 can be viewed from any position of the outdoor side 61.
In order to make the light visible, it is necessary to increase the area of the opening 50 so that the light is not blocked by the thick door 51. In order to do so, extensive installation work had to be performed, resulting in high costs. Further, providing the large opening 50 may impair the design and various performances of the door 51.

[0006]

The problem to be solved by the present invention is that, with a conventional door without a window, the lighting state of the room cannot be directly checked, and an opening is provided in the door to form a transparent body. In order to allow the light inside the room to be visible from any angle outside the room, the area of the opening must be increased.

[0007]

SUMMARY OF THE INVENTION Accordingly, the present invention is to provide a door which is formed with holes which are closed by a light-transmitting member on the inside and outside of the door, and each light-transmitting member is provided in the door. Optical fiber cables.

[0008] Since light is transmitted through the optical fiber cable, even in a small through hole, light is transmitted from the indoor side of the thick door to the outdoor side, and through a transparent body provided on the outdoor side, Light can be viewed from any angle.

Therefore, it is possible to confirm that the room is lit at a door without a window such as a toilet, for example, at night or in a dark place from outside the room.

[0010] Further, since an optical fiber cable capable of transmitting light without loss of light amount due to diffusion and absorption of light in the middle of the path is used, light inside the room is transmitted as it is to the outside of the room and high light is transmitted. Easy to see with brightness.

Furthermore, if at least one of the light transmitting members on the indoor side and the outdoor side is formed of a lens, the light is condensed and the luminance is improved, so that the light can be more easily recognized.

[0012]

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

FIG. 1 shows an example of an embodiment of the present invention. The present invention is applied to a door 1 having no window, such as a toilet, for example.

A hole 10 is provided at an appropriate position of the door 1, and a main body 21 of the light transmitting member 2 is fitted into the hole 10 from the outdoor side 11. The main body 21 is, for example, as shown in FIG.
A light transmitting body 22 formed of a lens is provided at the base end, and the optical fiber cable 3 connected to the light transmitting body 22 is built in on the center axis of the shaft portion 23, and a male screw 24 is formed at the tip.

Then, from the indoor side 12, the female screw 28 of the cover member 25 of the light transmitting member 2 is screwed into the male screw 24, so that the distal end of the optical fiber cable 3 is connected to the light transmitting member 2.
6. The lid member 25 is continuous with the light transmitting body 26 formed of a lens, and has a cylindrical portion 27 in which a female screw 28 is formed.
have.

Through the light transmitting member 2 thus connected,
Light is transmitted from the indoor side 12 to the outdoor side 11. Moreover, since the light is transmitted to the light transmitting body 22 without being attenuated by the built-in optical fiber cable 3, the light transmitting member 2 is inserted into a high place such as near the upper end of the door 1 as shown in FIG. Even in the vicinity of the lower end, light can be sufficiently viewed while standing in front of the door 1.

The light-transmitting member 2 is not limited to the above-described embodiment.
A transparent body such as a lens may be directly connected by an optical fiber cable and fitted into the hole 10.

The materials of the light transmitting members 22 and 26 are as follows.
Other than the lens, a transparent body such as glass or acrylic resin may be used.For example, if a transparent body or a lens with a color such as red or green is used, it is clearly distinguished from surrounding lights, and is easily recognized from a distance. Become.

[0019]

According to the present invention, since light is transmitted by the optical fiber cable without being absorbed into the door, electric wiring and the like are not required, the structure is simple, and the door is partitioned by a windowless window. Whether the room is lit or not can be clearly seen from outside even in a dark place.

Further, since it can be carried out even with an existing door by providing a small hole and inserting a translucent body connected by an optical fiber cable, manufacture and modification are easy, and the design and performance of the door are not impaired. Can be applied.

Further, since the light can be viewed from an arbitrary angle on the outdoor side, the light transmitting member may be fitted at any position of the door.

Further, since the translucent member is connected by the optical fiber cable, light can be transmitted even if the positions of the holes on the outside and the inside of the room are different.

Moreover, since it is impossible to see through even if light is transmitted, privacy can be protected.

If at least one of the light-transmitting members is a lens, the light transmitted through the optical fiber cable is condensed and the brightness increases, so that the light can be more easily recognized.
