JP 2010-254046 A

  However, when using the platform tile disclosed in Patent Document 1, the tile size of the existing tile and the tile of Patent Document 1 newly provided need to be the same. Therefore, when there are a plurality of types of platform tile sizes and shapes, it is necessary to manufacture platform tiles according to the tile size and shape, which is troublesome. In addition, since the tiles are exchanged, there is a problem that material costs increase and the installation of the thread line becomes expensive.

  There is also a construction method in which a long groove is drilled in the tile along the longitudinal direction of the existing platform, and a LED line is embedded in the long groove to newly establish a thread line. Need. Therefore, in the case where the train operation is performed in the daytime and the thread line is installed only by night work, it is difficult to establish a new thread line by the above construction method.

  An object of the present invention is to provide a floor-type display that can solve the above-described problems, has a high alerting effect, greatly reduces installation work time, and at the same time can newly install a thread line at low cost. is there.

In order to achieve the above object, a floor-type display according to the present invention has a flat mounting portion having a recess, a buried portion extending downward from the recessed portion, and an upper portion of the buried portion. A light-emitting unit fixed to the concave portion, and a light reflecting layer that reflects light upward is disposed on the bottom surface of the concave portion, and is made of a transparent resin immediately above the light reflecting layer. The light guide plate portion is disposed in a planar shape, the embedded portion extends downward from one end of the recess, and the light emitting portion is substantially horizontal with respect to the light guide plate portion in the recess , Light is emitted toward the other end of the recess .

  According to the floor type display of the present invention, the installation work time is compared with the conventional thread line construction method in which the tiles are replaced in the new construction of the thread line or a long groove is provided in the existing tile along the thread line. Can be greatly shortened. In addition, since a tile is not exchanged wastefully, a thread line can be newly established at a low cost.

  In addition, compared with conventional thread lines that emit point light, the floor-type display that emits light according to the present invention has a higher alerting effect and reflects light in the substantially horizontal direction incident from the light emitting portion to emit light. Therefore, it is possible to reduce the thickness of the floor display at the time of installation as much as possible.

  Moreover, since the floor-type display device according to the present invention is strong against the pressing force from above, there is little possibility of being damaged even if many platform users continue to step on for a long time. Furthermore, since the floor-type display is flat and the periphery is sloped, the user will not trip.

It is a perspective view of the floor type indicator of an example. It is a top view. FIG. 3 is a cross-sectional view taken along line A-A ′ of FIG. 2. FIG. 3 is a cross-sectional view taken along line B-B ′ of FIG. 2. It is explanatory drawing of the state which installed the floor-type display on the platform. It is explanatory drawing of the surface light emission of a floor type display.

The present invention will be described in detail based on the embodiments shown in the drawings.
1 is a perspective view of the floor-type display 1, FIG. 2 is a plan view, FIG. 3 is a sectional view taken along the line AA 'in FIG. 2, and FIG. 4 is taken along the line BB' in FIG. It is sectional drawing. In FIG. 4, the center portion of the floor display 1 is omitted.

  The floor-type display 1 includes a planar placement portion 2 that is placed directly on an existing platform, a cylindrical burying portion 3 that extends downward from one end portion of the placement portion 2, and The light emitting unit 4 is located above the embedded unit 3 and fixed to the recess of the mounting unit 2.

  The mounting portion 2 has a rectangular shape when viewed from above, and is provided with slope-shaped inclined portions 2a and 2b with a gentle inclination. The size of the mounting portion 2 is, for example, 1 m wide, 15 cm long, and the height of the top is about 1 cm. The horizontal and vertical lengths of these are appropriately selected according to the size of the existing tiles and the like. Is possible.

  The mounting portion 2 includes an inclined portion 2a along both long sides, an inclined portion 2b along both short sides, and a concave portion 2c surrounded by these inclined portions 2a and 2b. The inclined portions 2a and 2b and the concave portion 2c are made of a strong metal material, for example, a stainless steel plate having a thickness of 5 mm, an aluminum plate or the like. Although not shown in the inclined portions 2a and 2b, they will be described later at appropriate intervals. A through hole for fixing to the floor plate F of the platform to be formed is drilled.

  In the concave portion 2c, a white sheet layer 2d made of white or white sheet material and a light reflection layer 2e are laminated in this order from the bottom side, and a light guide plate portion 2f is laminated immediately above the light reflection layer 2e. . Only the white sheet layer 2d is provided on the inner surface of the recess 2c, and the white sheet layer 2d may be a mirror-like sheet body that reflects a lot of light.

  The light reflecting layer 2e is made of a synthetic resin sheet such as polycarbonate or acrylic. The surface of the light reflecting layer 2e is formed with a number of angled groove shapes, and the light reflectance increases as the distance from the light emitting portion 4 increases. That is, in the vicinity of the light emitting portion 4, the groove pitch is wide, for example, about 0.3 mm, and the angle of the mountain is gently formed. At a position away from the light emitting portion 4, the groove pitch is narrow, for example, about 0.1 mm. The angle of the mountain is sharp.

  The light guide plate portion 2f is made of a transparent synthetic resin such as polycarbonate or acrylic and is fitted in the recess 2c. The surface of the light guide plate portion 2f is continuous with the top portions of the inclined portions 2a and 2b without a step. The light guide plate portion 2f is a transparent flat body, and any material other than polycarbonate can be adopted as long as it has strength against pressing force from above.

  In addition, the thickness of the light guide plate portion 2f is substantially equal to the height of the side surface of the recess 2c. For this reason, the light guide plate portion 2f has a structure that is not easily damaged by the pressing force from above. In the case of manufacturing, a light guide plate portion 2f made of a plate material such as polycarbonate in consideration of the convex shape of the light emitting portion 4 may be prepared in advance, and fitted into the concave portion 2c to be fixed. Alternatively, in a state where the white sheet layer 2d and the light reflection layer 2e are laminated in the recess 2c, the melted polycarbonate can be filled in the recess 2c.

  The buried portion 3 is connected to the bottom surface of one end portion of the recess 2c with its central axis directed in the vertical direction. For example, the buried portion 3 has a cylindrical shape with a diameter of 10 cm, a height of 10 cm, and a wall thickness of about 3 mm, and a metal such as stainless steel or a synthetic resin having corrosion resistance in addition to the metal can be employed.

  On one side of the recess 2c to which the embedded portion 3 is connected, a rectangular hole 2g whose length substantially coincides with the short side of the recess 2c is provided along the short side of the recess 2c. At the upper end of the embedded portion 3, the light emitting portion 4 is fixed to the concave portion 2 c with the hole 2 g being inserted and a part protruding upward from the concave portion 2 c.

  The light emitting part 4 is fixed to the recess 2c by screwing or the like so as to close the hole 2g, and the surface of the light emitting part 4 protruding through the hole 2g emits light on the other end side of the recess 2c. A light emitting body 4a is provided. The light emitting main body 4a has a plurality of LED elements arranged in a line along the short side of the recess 2c, and emits light in a substantially horizontal direction.

  For example, a red high-luminance LED element suitable for alerting is preferably used for the line-shaped light-emitting main body 4a. In addition to the red high-intensity LED element, blue and green high-intensity LED elements can also be arranged together with the red high-intensity LED element.

  Alternatively, the embedded portion 3 and the light emitting portion 4 may be disposed at the center of the recess 2 c, and the light emitting main body portions 4 a that emit light in a substantially horizontal direction may be disposed on both surfaces of the light emitting portion 4. By arranging in this way, the distance to the far end is shortened, so that the surface emission can be made brighter than when the same high-intensity LED element is used.

  Further, an illuminance sensor may be provided on a part of the surface of the light emitting unit 4 to adjust the intensity of light emitted from the light emitting main body 4a according to the illuminance from the illuminance sensor. In this case, a control circuit for connecting the illuminance sensor to the light emitting unit 4 is also required.

  Below the light emitting part 4, a connecting part for connecting an external power cable line 4b is provided. Then, the power cable 4b is pulled in and connected from the bottom of the embedded portion 3 to cause the light emitting main body 4a to emit light. In addition, when arrange | positioning red, blue, and green high-intensity LED element, the power cable wire 4b corresponding to each color will be connected to a connection part.

  In this embodiment, only the power cable line 4b is connected to the controller unit 4c, which will be described later. However, the power cable line 4b is connected to the power supply device, and the signal line from the controller unit 4c is connected to the connection unit. May be. When connected in this way, by assigning an address to each light-emitting unit 4, each floor-type display 1 responds to a light-emission command via a signal line from the controller unit 4c. It is possible to perform lighting control.

  FIG. 5 is an explanatory view when the floor display 1 is installed on the platform. When installing the floor-type display 1, first, a circular hole having a diameter slightly larger than the diameter of the buried portion 3 is formed on the floor plate F of the existing platform located several tens of centimeters away from the longitudinal edge of the platform. Drill with a drill.

  And the floor surface type indicator 1 is mounted on the floor board F so that the edge part of the longitudinal direction of a platform and the mounting part 2 may become parallel simultaneously with the insertion of the embedding part 3 in this circular hole.

  Subsequently, the power cable 4b from the controller unit 4c shown in FIG. 5 installed outside is routed from the cavity below the floor board F and connected to the light emitting unit 4 through the embedded unit 3. The buried portion 3 protects the light emitting body 4a of the light emitting portion 4 which is an easily damaged electronic device and the connector parts of the connecting portion.

  Finally, after the final alignment on the floor plate F of the floor display 1, the anchor bolts are inserted into the through holes provided in the inclined portions 2 a and 2 b, and the floor display 1 is Fixing to the floor board F completes the installation work.

  By repeating such installation work, the floor-type display 1 is installed at a predetermined interval over the entire length in the longitudinal direction of the platform. As shown in FIG. 5, the light emitting unit 4 of the floor display 1 'installed adjacent to the light emitting unit 4 is also connected via the power cable line 4b branched from the controller unit 4c.

  Also, a thread line composed of a plurality of floor surface indicators 1 is arranged in each of the upward and downward directions of the platform, and the floor surface indicator 1 of one set of the upstream and downstream thread lines is connected to one controller unit 4c. It can be connected and controlled.

  The lighting control of the thread line composed of the plurality of floor-type indicators 1 is performed by on / off control of power supply of, for example, a DC 24V power cable line 4b from the controller unit 4c. The power supply on / off control is, for example, blinking control with a cycle of 100 ms.

  The plurality of floor-type indicators 1 constituting the thread line may be blinked synchronously, or by flashing while being shifted with respect to the adjacent floor-type indicator 1 ′, the light-emitting unit that is lit It is also possible to control blinking in order so that the light from 4 moves in the direction in which the train enters.

  For example, when the first to fourth floor-type display devices 1 are installed, the first floor-type display device 1 has a light emission timing of 0 seconds and the second lighting control that blinks while shifting. The floor-type display 1 has a light emission timing of 0.25 seconds, the third floor-type display 1 has a light emission timing of 0.5 seconds, and the fourth floor-type display 1 has a light emission timing of 0.75 seconds. Lighting control is performed from the controller unit 4c so that it is lit for about 200 ms at the light emission timing.

  By repeating this at a predetermined cycle, for example, at a cycle of 1 second, it is possible to turn on the light so that the light from the light emitting unit 4 of the first to fourth floor-type displays 1 moves in order. In addition, it can also be made to light so that light may move over the full length of the longitudinal direction of a platform by installing two or more sets of the 1st-4th floor-type display 1 adjacently.

  When the entire thread line is blinked synchronously, the controller unit 4c and the input unit of each floor surface display 1 of the thread line are connected in parallel. When the lighting control is performed by shifting the adjacent floor display 1 ', the light emitting unit of the floor display 1 and the controller unit 4c are connected in parallel at the same timing, and a plurality of timing floors are connected. The expression display 1 is separately input to the controller unit 4c.

  Further, by connecting a train interlocking device (not shown) to the controller unit 4c, the floor display 1 can be controlled to blink for a predetermined time in accordance with a condition that a train approach signal is input to the controller unit 4c.

  When red, blue, and green high-brightness LED elements are arranged in the light emitting body 4a, the common cable from the controller 4c and the power cable 4b corresponding to each color are connected to the connection of the light emitting unit 4. Based on the on / off control from the controller unit 4c, or when the above-described signal line is connected, it is possible to cause surface emission of an arbitrary color based on the light emission command signal from the controller unit 4c.

  For example, the floor display 1 can be blinked with different colors when a train passing through the platform approaches and when a train stopping on the platform approaches.

  FIG. 6 is an explanatory diagram for explaining the surface light emission of the floor display 1. The floor display 1 emits light perpendicular to the installation surface of the platform, road, or the like. The substantially horizontal light L emitted from the light emitting main body 4a has a higher light reflectivity as the distance from the light emitting part 4 increases. Therefore, the emitted light L travels through the light guide plate 2f in a substantially horizontal direction. It proceeds while repeating the reflection, and when it enters the angled slope of the light reflection layer 2e, it reflects upward and exits upward from the light guide plate portion 2f. A part of the light L incident on the slope of the angled groove shape of the light reflecting layer 2e is transmitted through the light reflecting layer 2e and reflected by the white sheet layer 2d below the light reflecting layer 2e.

  The light reflecting layer 2e does not reflect the strong light L1 in the vicinity of the light emitting main body 4a so much, but the light L2 weakened away from the light emitting main body 4a has a large reflection. Therefore, the floor surface type display 1 emits uniform surface light as a whole.

  When cracks or the like occur in the light guide plate portion 2f of the floor-type display 1 or the inclined portions 2a and 2b are damaged, the anchor bolt that fixes the floor-type display 1 is removed, and the floor-type display After the display device 1 is removed, the new floor-type display device 1 can be easily restored from the failure state by installing it with the above construction method.

  In addition, when a problem occurs in which part or all of the light-emitting main body 4a of the light-emitting unit 4 of the floor-type display 1 is not lit, restoration by replacement of the floor-type display 1 as described above. In addition, after removing the floor-type display 1, remove the failed light emitting part 4 etc. from the bottom of the open buried part 3 and replace it with a new part to restore it. Also good.

  As described above, according to the floor-type display 1 of the present embodiment, the work time of the new construction of the thread line is replaced with the conventional tile, or the thread line in which a long groove is provided in the existing tile along the thread line. Compared with the construction method, it can be significantly shortened. In addition, since the tiles are not exchanged wastefully, it is possible to newly establish a thread line at a low cost.

  Further, the light on the horizontal direction from the light emitting unit 4 is irradiated into the light guide plate unit 2f, and the white sheet layer 2d and the light reflecting layer 2e are emitted from the upper light guide plate unit 2f to cause surface light emission. The thickness of 2 can be reduced. At the same time, as in a conventional thread line, a surface emitting effect is more effective than point emitting at a predetermined interval.

  Further, since the floor-type display 1 is strong against the pressing force from above, even if many platform users step on it for a long time, it will not be damaged. Furthermore, since the floor-type display 1 has a flat shape and the periphery is sloped, there is no possibility that the user will trip.

  In the present embodiment, the floor display 1 is described as being installed on the platform as an example, but it can also be used as a light emitting device for alerting at an appropriate place such as a road. In addition, even in a place where the power cable line 4b cannot be laid, a storage battery connected to the solar panel in the buried portion 3 using the inclined portion 2a made of a metal plate in which the solar panel is disposed under the polycarbonate plate is provided. By arranging it, it is also possible to operate as a power self-contained floor display 1.

  Alternatively, it is possible to operate a battery that can be flashed over a period of several years by incorporating it in the embedded unit 3 and receiving a lighting control signal from the central device by the wireless communication unit provided in the light emitting unit 4. It is also possible to perform flashing control.
