Abstract

PROBLEM TO BE SOLVED: To confirm whether or not an indoor section separated from a door is lit easily even at night and at a dark place. SOLUTION: Openings 20 closed by light-transmission bodies 4 are formed to handles or seats 2 supporting the handles disposed on the indoor side 12 and the outdoor side 11 of the door 1 respectively while the light-transmission bodies 4 are connected by an optical fiber cable 5 in the door 1. When a lens is used as at least one of the light-transmitting bodies 4, 4, light transmitted by the optical fiber cable 5 is focussed, and is easy to be recognized visually.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a handle such as a door knob or a door handle attached to a hinged door or a sliding door or a handle.

[0002]

2. Description of the Related Art In conventional doors such as hinged doors and sliding doors,
As a means for indicating whether the room is in use, when a key such as a thumb turn is locked from inside the room, a color display such as red is generally displayed near the handle outside the room, At night or in a dark place, the display is difficult to see, 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. When the power distribution unit breaks down, there is a problem that the lighting in the room cannot be recognized.

[0004]

The problem to be solved by the present invention is that it is difficult to confirm whether or not the room is in use at night or in a dark place with the conventional door. The switch is turned on because the structure is complicated, and if the light bulb in the switch portion does not turn on, the lighting in the room cannot be recognized.

[0005]

SUMMARY OF THE INVENTION In view of the above, the present invention provides a handle or a seat for supporting a handle provided on the indoor side and the outdoor side of a door, respectively, to form openings closed by a light transmitting body. At the same time, the translucent member is connected by an optical fiber cable provided in the door.

[0006] When the light inside the room is transmitted to the outside of the room through the light-transmitting member connected by the optical fiber cable, it is possible that the room is lit at night or at a door without a window such as a toilet. It can be checked from outside even in a dark place.

Therefore, in addition to confirming that the interior of the room is lit, if the exterior or the interior is bright, the position of the door or the handle can be visually recognized even at night or in a dark place. It is possible to check if the user has forgotten to turn off the light from outside.

Further, by using an optical fiber cable capable of transmitting light without a loss of light amount due to diffusion and absorption of light in the middle of the path, light inside the room is transmitted to the outside of the room as it is. Brightness can be displayed and it is easy to see. Further, if at least one of the light-transmitting members that close the openings on the indoor side and the outdoor side is formed of a lens, the light is condensed, the luminance is improved, and the light is more easily recognized.

[0009]

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

FIGS. 1 and 2 show an example of an embodiment of the present invention, which is carried out for a door without a window, such as a toilet.

A lever handle 3 is attached to an upper part of the seat 2, and a light transmitting body 4 is fitted into a lower part of the lever handle 3. Further, the door 1 is provided with a hollow portion 10 for installing the internal structure of the lock or for penetrating the support shaft of the handle 3, and the light transmitting body 4 is provided as shown in FIG. The light-transmitting members 4, 4 of the outdoor side 11 and the indoor side 12 are connected by an optical fiber cable 5 so as to close the outdoor side 11 and the indoor side 12 of the opening 20 penetrating the seat 2. Therefore, light is transmitted from the indoor side 12 to the outdoor side 11 or in the opposite direction through the optical fiber cable 5, and the light can be visually recognized through the light transmitting body 4.

The light transmitting members 4 and 4 are condensed by using both or one of them as lenses to increase the luminance, so that the light can be easily recognized.

Further, the material of the light transmitting member 4 may be a transparent member such as glass or acrylic resin other than the lens.
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 even from a distance.

The handle is not limited to a lever handle, but may be a grip ball or another handle.

FIGS. 3 and 4 show a different embodiment of the present invention, and a handle 3 attached to a sliding door or the like.
1, the present invention is applied. Toride 31
A box-shaped main body 32 formed in a U-shaped cross section has a flange 33 on the upper peripheral edge, and a light transmitting body 34 made of a lens is fitted on the surface of the upper end of the flange 33.

Then, such a handle 31 is connected to the outdoor side 2.
1, provided on both the indoor side 22 and the respective light transmitting bodies 3
4 and 34 are connected by an optical fiber cable 35.

In this case, the handles 31 of the sliding door 11 may be provided on both sides of the outdoor side 21 and the indoor side 22 as shown in FIG. 4, or may be provided on either one of them as shown in FIG. If one is provided,
A hole 40 is formed on the side of the door 41 where the handle 31 is not provided, and a light transmitting body 44 is fitted. The light transmitting body 44 and the light transmitting body 34 provided on the handle 31 are connected to the optical fiber cable 3.
Connect with 5.

As described above, in either case of a door having a lever handle or a grip ball and having a hollow portion formed between the outside and the inside of the room, or a sliding door without such a door, any door can be used. Also, light can be conducted to each other on the opposite side of the door through an optical fiber cable.

[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, even an existing door can be easily mounted simply by changing the handle or seat, and even if the door has no hollow portion between the outside and the inside of the room, a hole can be opened. Since an optical fiber cable may be inserted, the present invention can be easily applied to any door.

Further, since the light transmitting members on both sides of the door are connected by the optical fiber cable, light can be transmitted through the optical fiber cable even if the positions of the light transmitting members on both sides of the door do not match.

Further, if at least one of the light transmitting members is a lens, the light transmitted through the optical fiber cable is further condensed, so that the light can be easily recognized.

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

Further, when the hallway is dark even in the daytime, such as in an apartment, if the room is turned on, the position of the door handle can be recognized without turning on the hallway. When it is dark, the outdoor light leaks from the translucent body, so that the position of the door handle can be instantly recognized in an emergency or the like. In addition, it is possible to confirm from the outside that the user has forgotten to turn off the light in the room, which contributes to energy saving.
