Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to an apparatus for displaying an empty state of a taxi vehicle.
[0002]
[Prior art]
In general, the taxi vehicle's empty state can be recognized directly by looking at the curtain-type or light-emitting wind sign on the dashboard through the windshield, and at night to display the taxi company It is possible to recognize it in the dark by checking the lighting of a row lamp, commonly called a “lantern”, installed on the roof of a taxi vehicle.
[0003]
However, the display of the empty vehicle status by the wind sign has the disadvantage that it is difficult to see because it is hidden behind the vehicle in a traffic jam, and the display of the empty vehicle status by lighting the row lights is a promise of an unliterate character. This is not effective for those who do not know, and the lighting of the row lights is limited to the night when the headlights are turned on, so that it does not function at all in the daytime.
[0004]
Therefore, for example, as disclosed in Japanese Patent Application Laid-Open No. 2-28689, Japanese Utility Model Laid-Open No. 2-19188, and Japanese Utility Model No. 3045831, a device for displaying an empty vehicle state is installed on the roof of a taxi vehicle. However, all of them have a drawback that the direction in which the display of the empty vehicle state can be visually recognized is limited to the front-rear direction of the taxi vehicle, for example.
[0005]
Further, as a proposal that can solve the problems of the devices of the above-mentioned publications, a rooftop display device for an automobile according to Japanese Patent Application Laid-Open No. 8-2341, which discloses rotating a light-emitting display on the roof of a taxi vehicle, has been conventionally disclosed. Exists.
[0006]
[Problems to be solved by the invention]
However, in the above-described automobile rooftop display device, since the display is based on the light emitting display, it is difficult to function sufficiently in the daytime as in the case of the first-mentioned row lamp unless the light emission brightness is very high, and the light emitting display is used. Therefore, it is useful when it has an advertising function, etc., but it is a little expensive as a device that only performs empty display, and in addition, the electrical wiring is routed to the rotating light-emitting display. Since it must be devised so that there is no disconnection due to twisting or the like, it must be said that it lacks practicality.
[0007]
The present invention has been made in view of the above circumstances, and the object of the present invention can be simplified not only in the electrical wiring but also in the structure. An object of the present invention is to provide an empty display device for a taxi vehicle that can recognize an empty state from an arbitrary direction without being obstructed.
[0008]
[Means for Solving the Problems]
In order to achieve the above object, a taxi vehicle empty display device according to the present invention is a device for displaying an empty vehicle state when a taxi vehicle is operating, and is arranged rotatably on the roof of the taxi vehicle. A rotation display member that is provided, at least two of the rotation display members, a display surface in which the position of the rotation display member on the roof in the rotation direction is changed by the rotation of the rotation display member, and each of the displays Each of the divided characters formed on the surface, and rotational power applying means for applying power for rotation to the rotating display member when the taxi vehicle is running empty. An empty vehicle table showing an empty state of the taxi vehicle by superimposing afterimages of the divided characters on the display surfaces viewed from an arbitrary direction during rotation. Characterized in that it is configured to be identified as a use character.

DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of an empty vehicle display device for taxi vehicles according to the present invention will be described with reference to the drawings.
[0015]
1 and 2 are both perspective views of the taxi vehicle empty display device according to the embodiment of the present invention as viewed from above, and the taxi vehicle of the present embodiment indicated by reference numeral 1 in FIGS. 1 and 2. The empty vehicle display device is configured to have a substantially cylindrical shape as a whole by the base portion 3 and the display portion 5.
[0016]
The base portion 3 is installed on the roof of a taxi vehicle (not shown), and is formed of a colored resin molding material or the like so that the inside cannot be seen. A motor (not shown) that is energized and driven only when an empty car tariff is interlocked with the operation of the tariff button of the taximeter shown in the figure is accommodated, and the output shaft 7 of this motor (not shown) It is inserted and protrudes upward.
[0017]
The display unit 5 has a cylindrical shape with the upper end closed as a whole, and an open lower end attached to the base unit 3 with water-tightness secured thereto. A rectangular rotation display plate 11 (corresponding to a rotation display member) is housed, and a central portion in the left-right direction is attached to the tip of the output shaft 7 of the lower side of the rotation display plate 11. Thus, the rotary display plate 11 extends in the radial direction of the output shaft 7.
[0018]
The rotation display board 11 is configured to rotate about the extension line of the output shaft 7 as a rotation center when the output shaft 7 is rotated by energization of a motor (not shown) in the base portion 3.
[0019]
Further, as shown by a solid line in the explanatory diagram of FIG. 3, a first divided character 17 composed of five lines 15a to 15e is formed on the surface 13 (corresponding to the display surface) of the rotary display board 11, On the contrary, as shown by an imaginary line in FIG. 3, on the back surface 19 (corresponding to the display surface) of the rotary display plate 11, the character “empty” of the empty vehicle (empty vehicle) can be seen by overlapping with the first divided character 17. A second divided character 23 composed of four lines 21a to 21d is formed so as to constitute a display character).
[0020]
Each of the first and second divided characters 17 and 23 is configured by drawing lines 15a to 15e and 21a to 21d on the corresponding front and back surfaces 13 and 19 with a fluorescent paint.
[0021]
As is clear from the above description, in this embodiment, the rotational power applying means in the claims is constituted by a motor (not shown) in the base portion 3.
[0022]
Next, the operation (action) of the taxi vehicle sky display device 1 of the present embodiment configured as described above will be described.
[0023]
First, since the rotation display plate 11 of the taxi vehicle empty display device 1 is covered with the transparent cover 9, the rotation display plate 11 on the inner side can be visually recognized no matter what direction the display unit 5 is viewed.
[0024]
However, when the taxi vehicle is a real car tariff, the motor (not shown) is not energized and the rotary display plate 11 does not rotate with the output shaft 7. Even if the display portion 5 is viewed from the viewing direction in which the front and back surfaces 13 and 19 of the rotary display plate 11 can be seen through the transparent cover 9, the thin end surface of the rotary display plate 11 is merely visually recognized. Only the first or second divided characters 17 and 23 that constitute a part of the “sky” character are visible on each surface 13 and 19.
[0025]
Therefore, no matter which direction the display unit 5 is viewed from, the image that can be recognized as the “sky” character cannot be seen through the transparent cover 9.
[0026]
On the other hand, when the taxi vehicle is empty, a motor (not shown) is energized and the rotation display plate 11 rotates together with the output shaft 7, so that the rotation display plate 11 can be viewed from any direction. The afterimages of the first and second divided characters 17 and 23 on the front and back surfaces 13 and 19 are visible, and the afterimages of the first and second divided characters 17 and 23 are visually superimposed. Will be.
[0027]
Therefore, the person who has seen the display unit 5 can visually recognize an image that can be recognized as the “sky” character through the transparent cover 9 regardless of the direction from which the display unit 5 is viewed.
[0028]
In addition, at night time, on the roads 15a to 15e and 21a to 21d drawn on the front and back surfaces 13 and 19 with fluorescent paint to form the first and second divided characters 17 and 23, respectively, illumination on the road Or a headlight of a surrounding vehicle is irradiated through the transparent cover 9, and the fluorescent substances in the fluorescent paints of these lines 15a to 15e and 21a to 21d are excited to emit light, and the first of the front and back surfaces 13 and 19 is emitted. And each 2nd division | segmentation character 17 and 23 is light-emitting displayed.
[0029]
In addition, the arrangement of the taxi vehicle empty vehicle display device 1 on the roof of the taxi vehicle can be arranged at any place such as immediately next to a row lamp indicating the name of an existing taxi company or a roof portion slightly spaced forward and backward from this row lamp. can do.
[0030]
Thus, according to the taxi vehicle sky display device 1 of the present embodiment, the motor housed inside the base unit 3 is mounted on the display unit 5 on the base unit 3 that is rotatably arranged on the roof of the taxi vehicle. A rectangular rotation display plate 11 attached to the output shaft 7 and a transparent cover 9 covering the rotation display plate 11 are provided, and the rotation display plate 11 is output by energizing the motor when the taxi vehicle is empty. The first and second divided characters 17, 17, respectively, constituting the different parts of the “empty” character formed on the front and back surfaces 13, 19 of the rotary display board 11 by rotating together with the shaft 7. 23 afterimages are visually recognized by a person who has seen the display unit 5, and the afterimages of the first and second divided characters 17 and 23 are visually overlapped with the characters “sky” through the transparent cover 9. I saw the recognizable image on the display 5 It was configured to be visible to.
[0031]
For this reason, “sky” which is an afterimage in which the first and second divided characters 17 and 23 are superimposed on a person who viewed the display unit 5 when the taxi vehicle is in an empty tariff from any direction around the taxi vehicle. The image that can be recognized as the character of is clearly visible through the transparent cover 9 and can recognize that the taxi vehicle is in an empty state.
[0032]
On the other hand, for the person who has seen the display unit 5 at the time of the actual taxi vehicle tariff, “sky” which is an afterimage in which the first and second divided characters 17 and 23 are superimposed from any direction around the taxi vehicle. It is possible to prevent the taxi vehicle from being recognized in an empty state by reliably not recognizing the image that can be recognized as the character of the above through the transparent cover 9.
[0033]
And according to the empty vehicle display device 1 for taxi vehicles of this embodiment, since it is arrange | positioned on the roof of a taxi vehicle, it is a surrounding vehicle compared with the wind sign conventionally installed and used on a dashboard. This makes it possible to recognize the vacant state of a taxi vehicle without being disturbed.
[0034]
Moreover, since no electrical configuration is required for the afterimage display of the first and second divided characters 17 and 23, the electrical wiring is not connected to the rotating display panel 11 so as to be disconnected due to twisting or the like. Since it does not need to be devised and routed, it can be improved structurally and maintainability such as maintenance and repair, and can be inexpensive because it does not require costly parts such as light-emitting displays. Can be.
[0035]
The lines 15a to 15e and 21a to 21d forming the first and second divided characters 17 and 23, respectively, are drawn on the front and back surfaces 13 and 19 of the rotary display plate 11 with a paint other than the fluorescent paint. Alternatively, the lines 15a to 15e and 21a to 21d may be respectively drawn on the front and back surfaces 13 and 19 by a method other than the application of paint.
[0036]
However, if the lines 15a to 15e and 21a to 21d are respectively drawn on the front and back surfaces 13 and 19 of the rotary display plate 11 by applying a fluorescent paint, as in the taxi vehicle blank display device 1 of the present embodiment. The afterimages of the first and second divided characters 17 and 23 visually recognized by the person who has seen the display unit 5 by the rotation of the rotary display board 11 are displayed as light emission displays, in particular, the first and second each at dark night. This is advantageous because the visibility of the afterimages of the divided characters 17 and 23 can be improved and the degree of recognition that the taxi vehicle is in an empty state can be improved.
[0037]
In order to exert such an effect, instead of drawing the lines 15a to 15e and 21a to 21d on the front and back surfaces 13 and 19 by applying a fluorescent paint, the lines 15a to 15e and 21a to 21d are drawn. A fluorescent paint is applied to the surrounding front and back surfaces 13 and 19 except for the first and second divided characters 17 and 23 on the front and back surfaces 13 and 19 in the form of design removal. You may do it.
[0038]
Further, in the taxi vehicle empty display device 1 of the present embodiment, the rotational power applying means in the claims is constituted by a motor (not shown) in the base portion 3, and this motor is energized and driven only when the taxi vehicle is empty. The rotation display plate 11 is rotated when the taxi vehicle is empty, but the rotational power applying means may be replaced with a different configuration.
[0039]
For example, the transparent cover 9 is formed with an air intake port that allows the outside and the inside of the transparent cover 9 to communicate with each other, and the wind received by the display unit 5 while the taxi vehicle is traveling is introduced into the transparent cover 9 from the air intake port. The wind is applied to a portion closer to one end of the rotation display plate 11 in the left-right direction, and the rotation display plate 11 is allowed to rotate when the taxi vehicle is empty, and the brake means is used to prevent the rotation when the taxi vehicle is the actual vehicle. The configuration of the rotational power applying means can be arbitrarily changed, for example, by providing the rotational power applying means so as to rotate the rotation display plate 11 by wind power by providing it in the section 3.
[0040]
Moreover, in the taxi vehicle blank display device 1 of the present embodiment, the first and second divided characters 17 and 23 are formed on the front and back surfaces 13 and 19 of the single rotation display board 11 having a rectangular shape. The surface corresponding to the display surface in the claims is composed of two surfaces. For example, an extension line of the output shaft 7 is used as a rotation axis, and the rotation axis is set as a center and spaced in the circumferential direction. A plurality of plate members are each radially extended in the radial direction of the rotation axis, and when they are all over the surface of two adjacent plate members, a divided character that constitutes an “empty” character is drawn. The surface corresponding to the display surface in the item may be three or more.
[0041]
However, if the taxi vehicle empty display device 1 of the present embodiment has two surfaces corresponding to the display surface in the claims, the taxi vehicle when the rotation display plate 11 does not rotate can be used when the vehicle is in the tariff. If the range of the viewing direction in which the surface corresponding to the display surface in the claims is not visible is set wider, it may be difficult to see the divided characters whose meaning is unclear even when viewed by the person who has viewed the display unit 5 alone. This is advantageous.
[0042]
Further, in the taxi vehicle empty display device 1 of the present embodiment, the empty display character in the claims is the character “empty” of the empty vehicle, but the empty vehicle display character is limited to the character “empty”. Needless to say, the character may be “empty car” or may be other than a character such as a symbol mark meaning “empty car”.
[0043]
【The invention's effect】
As described above, according to the taxi vehicle empty display device of the present invention described in claim 1, it is a device for displaying an empty vehicle state when the taxi vehicle is operating, and is rotatable on the roof of the taxi vehicle. A rotation display member to be arranged; at least two of the rotation display members; a display surface in which a position on the roof in a rotation direction of the rotation display member is changed by rotation of the rotation display member; A split character formed on the display surface; and a rotational power applying means for applying power for rotation to the rotary display member during empty driving of the taxi vehicle, wherein each of the split characters is the rotary display member. An empty vehicle indicating an empty state of the taxi vehicle by superimposing the afterimages of the divided characters on the display surfaces viewed from an arbitrary direction during rotation of the taxi vehicle示用 was assumed to be configured to be identified as a character.
[0044]
For this reason, during empty driving of a taxi vehicle in which the rotary display member is rotated by the power applied by the rotational power applying means, it is practically difficult to recognize the empty state by using a light emitting display or lighting. However, the vacant state of the taxi vehicle can be recognized without being restricted by the viewing direction, by the afterimages of the divided characters on each display surface that are superimposed on each other and identified as the vacant display character.
[0045]
On the other hand, when the taxi vehicle does not rotate depending on the power applied by the rotational power applying means, the divided character that cannot be identified as the empty vehicle display character is stopped at most so that the taxi vehicle can be visually recognized. It is possible to prevent recognition of an empty vehicle state.
[0046]
Moreover, according to the empty display device for taxi vehicles of this invention described in Claim 2, in the empty display device for taxi vehicles of this invention described in Claim 1, the said rotation display member is rotation of this rotation display member. It is assumed that it has a flat plate shape extending in the radial direction of the shaft, and each of the front and back surfaces of the rotating display member constitutes the display surface.
[0047]
For this reason, in addition to the effect of the taxi vehicle empty display device of the present invention described in claim 1, the taxi vehicle does not rotate depending on the power applied by the rotational power applying means, when the taxi vehicle is operating empty, It is possible to secure a wide range in which an unintelligible divided character that cannot be identified as an empty car display character cannot be visually recognized.
[0048]
Furthermore, according to the taxi vehicle empty display device of the present invention described in claim 3, in the taxi vehicle empty display device of the present invention described in claim 1 or 2, each of the divided characters has fluorescence. It was set as the structure each formed in each said display surface by application | coating with respect to the said rotation display member of a coating material.
[0049]
For this reason, in addition to the effect of the taxi vehicle empty display device of the present invention described in claim 1 or 2, the taxi vehicle empty vehicle in which the rotation display member is rotated by the power applied by the rotational power applying means. During operation, the empty display character that is recognized by overlapping the afterimages of the divided characters on each display surface by the fluorescent substance in the paint on each display surface excited and emitted by the light irradiated on the rotating display member is used as the light emission display. In particular, the visibility of the empty vehicle display character at night can be improved.
