[0014]
DETAILED DESCRIPTION OF THE INVENTION
An embodiment of the present invention will be described below with reference to the drawings.
[0015]
A partition device 1 according to the present embodiment is used for a guard fence provided on a platform of a Shinkansen station, for example, and as shown schematically in FIG. 1, a plurality of optical fibers 2 and light are transmitted. Light to be introduced is emitted to the light transmitting body 3 having a rectangular plate shape that can be transmitted, the frames 61 to 64 disposed around the light transmitting body 3, and the end faces 22 and 23 of the optical fiber 2. The LED 4 is a light emitter, and a holding mechanism 5 that holds the optical fiber 2 along the face plate direction of the light transmitting body 3.
[0016]
As shown in FIG. 2, FIG. 3, and FIG. 4, the optical fiber 2 is a flexible thin wire composed of a core 2a and a clad 2b. A plurality are formed. Specifically, a cut K is formed on the side surface of the optical fiber 2 by, for example, laser processing or machining, light is reflected by the cut K, and light is emitted from the opposite side surface. The light emitting part 21 is used. The cut K is cut into a substantially V-shaped cross section so as to be orthogonal to the axis of the optical fiber 2 and has a depth reaching the core 2a. Of the light introduced from the end faces 22 and 23 of the optical fiber 2 and traveling in the axial direction due to the difference in refractive index between the core 2a and the clad 2b, the light hitting the notch K is diffusely reflected there, and on the opposite side. It leaks out from the light emitting part 21 which is the side of the outside. At this time, the light reflected by the cut K due to the lens effect of the optical fiber 2 is refracted in the converging direction. Therefore, the light emitted from the cut K is visually enlarged when viewed from the outside. It will appear to shine throughout.
[0017]
As shown in FIGS. 1 and 5, the light transmitting body 3 is formed by filling a pair of rectangular transparent glass plates 31 that are colorless transparent plates and the glass plates 31 so as to be spaced apart from each other by a predetermined distance, for example. And a colorless transparent material 32 made of resin.
[0018]
As shown in FIG. 1, the frames 61 to 64 are, for example, metal or resin hollow inside, and are arranged so as to cover the peripheral edge of the light transmitting body 3 from the front and back.
[0019]
The LED 4 is of a type called an ultra-high brightness power LED that can continuously pass a current of, for example, 200 mA to 300 mA or more.
[0020]
As shown in FIG. 5, the holding mechanism 5 is configured using a pair of glass plates 31 and a transparent material 32 sandwiched between them, and the optical fiber 2 is interposed between the pair of glass plates 31. The optical fiber 2 is fixedly held by restricting the movement of the optical fiber 2 in the direction perpendicular to the direction of the face plate while being sandwiched and restricting the movement of the optical fiber 2 along the face plate direction by the transparent material 32. It is. Specifically, for example, a transparent material 32 having a plate shape is intermittently disposed between the glass plates 31, and the light enters the fiber insertion hole 5 a penetrating from side to side surrounded by the transparent material 32 and the glass plate 31. The fiber 2 may be held, or as shown in FIG. 11, the optical fiber 2 is first disposed between the glass plates 31, and then the liquid transparent material 32 is filled between the glass plates 31 and solidified. It does not matter if you make it.
[0021]
In the present embodiment, a plurality of the fiber insertion holes 5a are provided in the vertical direction, and a plurality of optical fibers 2 are arranged in parallel at equal intervals in the vertical direction. Thus, each end of the optical fiber 2 is positioned in the left and right frame bodies 62 and 63, and the LED 4 is disposed in the left and right frame body 6 at a position facing the end surfaces 22 and 23. In FIG. 1, a total of two LEDs 4 are provided, one on each end face 22, 23 of each optical fiber 2.
[0022]
The partition device 1 further includes a power source 7 that supplies power to each LED 4 and controls the blinking thereof. The power source 7 is accommodated in a lower frame 64 as shown in FIG. A power cable CA from the power source 7 passes through the frame 6 and is connected to the LEDs 4.
[0023]
As described above, in the present embodiment, a plurality of optical fibers 2 extending in the left-right direction are arranged in the vertical direction, and the optical fibers 2 are arranged in parallel to a predetermined internal region of the light transmitting body 3. The light emitting sections 21 provided in the optical fibers 2 are all configured to face one surface of the light transmitting body 3 as shown in FIG. 5, and the formation positions of the light emitting sections 21 are appropriately set. Thus, when the LED 4 is turned on and viewed from the one surface, the light is emitted outwardly from the light emitting portion 21 so that it can be visually recognized, for example, “STOP” in FIG. ing.
[0024]
Therefore, according to the present embodiment, it is possible to display on the light transmissive body 3 with a very simple configuration that emits light brightly and easily in the daytime without impairing its transparency. And it is possible to display a warning or the like for anything that is used outdoors in the daytime, such as a protective fence of a station, and needs to be seen through. In particular, in the present embodiment, the power LED 4 is used as the light emitter, and light is introduced from both end faces 22 and 23 of the optical fiber 2, so that the light emitted from the light emitting portion 21 is strong and the effect is remarkable. It will be something.
[0025]
The present invention is not limited to the above embodiment.
[0026]
For example, as shown in FIG. 7, a large number of cuts K (light emitting portions 21) may be provided so that substantially the entire optical fiber 2 emits side light. In this case, as the distance from the end faces 22 and 23 increases, the light weakens. Therefore, in order to emit light uniformly in a line shape, the formation density of the cut K is minimized in the vicinity of the end faces 22 and 23, and the density is gradually increased from there. In addition, it is preferable that the formation density of the cuts K be the highest in the portion farthest from the end faces 22 and 23, that is, in the central portion.
[0027]
Moreover, you may change the color of the light introduce | transduced into each optical fiber 2, respectively. For example, while using the optical fiber 2 that shines in a line shape as described above, as shown in FIG. 8, the LEDs 4 of three colors of blue, red, and yellow are used, and they are alternately arranged to selectively emit light. By doing so, the partition device 1 can be given a role like a signal. In this figure, the LED 4 is called a power LED, and a plurality of optical fibers 2 are connected to one power LED 4 of each color. In the figure, reference numeral CS denotes a casing containing one power LED 4. In addition, for example, the display can be made dynamic by dynamically lighting the LED 4.
[0028]
Further, as shown in FIG. 9, each end of the optical fiber 2 is positioned on a frame 63 (61, 62, 64) corresponding to any one side of the light transmitting body 3, and the optical fiber 2 is looped. You may make it wind in a shape. In this case, the position of the LED 4 is preferably the frame body 63 (61, 62, 64) on the one side, but the position of the LED 4 is set to a frame body different from the frame body where the end of the optical fiber 2 is positioned. The optical fiber 2 may be extended to the position of the LED 4.
[0029]
In addition, as shown in FIG. 10, the position, size, and shape of the cut K may be different from each other, the mode of the light emitting portion 21 may be different from each other, and the display may be given variations. The portion may be bent or twisted to be the light emitting portion. Of course, the optical fiber may be held not only in a straight line but also in a curved shape. Light may be introduced only from one end face of the optical fiber.
[0030]
Of course, the optical fiber may be fixed to the glass plate with a transparent adhesive.
[0031]
If the position of the power source is also applied to a fixed object such as the protective fence, it may be installed in the frame 6 or in the vicinity thereof. For example, if it moves like a sliding door of a railway vehicle, the power source May be installed in a predetermined part other than the door, and the power cable may be connected to the power source from the door pocket.
[0032]
In addition, unlike the above-described embodiment, the light transmitting body may be formed of a single transparent plate. In that case, for example, an optical fiber may be inserted and held in the fiber holding groove by forming a fiber holding groove opened on the surface. Of course, even if this partition device is applied to a partition device other than a guard fence or a door, the same effects as those of the above-described embodiment can be obtained.
[0033]
In addition, the present invention is not limited to the above illustrated example, and various modifications can be made without departing from the spirit of the present invention.
[0034]
