Description

  The present invention relates to a traffic light and a traffic light cover.

A departure signal is installed at the train station platform to check whether the driver can leave the train. However, the conductor may not be able to see the departure signal from the crew room depending on the length of the train that arrives at the platform. In such cases, a signal called a departure reaction sign is installed in the station building in addition to the departure signal. (Non-Patent Document 1). This departure reaction sign is usually hung from the ceiling of the station building and installed at a position where it can be visually confirmed from the crew room.

  However, since the departure reaction sign is fixed to the station building so that it can be seen from the conductor, there is a pseudo-indication (phantom) that appears as if it is lit even though it is not lit because of the sunlight. ).

  Accordingly, an object of the present invention is to solve the above-described problems and provide a traffic light that is unlikely to generate a false indication and a traffic light cover that is attached to the signal.

  In the case of the traffic light described in claim 1 made to solve the above-described problems, a light emitting portion is formed on a front display side surface for displaying a signal. The light emitting unit may be a plurality of LEDs directly mounted on the display side surface of the housing, or may be a hole that includes a lamp inside the housing and emits light emitted from the lamp.

The traffic light described in claim 1 includes a plurality of cover plate portions that are formed in a plate shape and in which holes are formed in a dotted shape on the plate surface, and forward from above the display side surface. The light emitting part is covered with the eaves part erected upward, so that sunlight can be prevented from entering the light emitting part.

Each cover plate portions, in front of the light emitting portion, Rutotomoni is installed such plate surface is inclined forward and obliquely downward, in front of the light emitting portion, is arranged forward obliquely upward from the lower rear side It is comprised so that a light emission part may be covered.
In this case, the false display (phantom) is prevented by experiment, so that the blinking of the light emitting unit can be reliably recognized. The factor that makes the blinking visible is that even if sunlight is inserted into the light emitting part, the light is cut off in the part other than the hole part of the cover plate part , and the light emitting part has sufficient brightness to cause a false indication. thought can not be obtained when the plus Ru.
Although the cover plate portion may be disposed inside the collar portion, it is not necessary to be completely disposed inside the collar portion due to various circumstances such as the shape of the collar portion, and a part of the cover plate portion is It does not prevent you from going outside.

Moreover, it is preferable that a hole is formed in a cover plate portion other than the cover plate portion arranged on the most front side, and no hole is formed in the most front cover plate portion . In this way, if the hole is not formed in the frontmost cover plate part , sunlight is less likely to enter the light emitting part than in the case of the sole part alone, so that the false indication can be prevented more reliably. Can do.

Furthermore, the diameter of the hole is preferably 1 mm to 3 mm. If the diameter of the hole is 1 mm or less, the light emitted from the light emitting part is difficult to visually recognize on the front side, and if it is 3 mm or more, the effect of preventing the penetration of sunlight into the light emitting part is diminished, This is because it becomes difficult to effectively prevent the false indication. When a 3 mm hole is provided, it is preferable that approximately 8 holes are formed per 1 cm ² .

Next, a general traffic light that does not include the above-described cover plate portion is provided with each cover plate portion , and if a signal device cover configured to be removable with respect to the collar portion is attached, it is possible to effectively prevent the false indication. it can. In addition, since the traffic signal cover is configured to be removable, when the traffic signal body is replaced, it can be reused by removing the traffic signal cover from the old traffic signal and attaching it to the new traffic signal.

  As a specific detachable configuration, a hooking portion that can be hooked to the front end of the collar part is provided at one end, and when this hooking part is hooked to the tip of the collar part, the display side surface below the light emitting part is provided. It is preferable to provide the other end with a fixing portion that can be fixed by contact. The traffic signal cover may be fixed to the display side surface by the fixing portion after being hooked on the tip of the bag by the hook portion. When removing it, you can easily remove it by releasing the fixing part and pulling it toward you.

The traffic signal cover includes a cover plate portion . The signal cover includes a support member installed in parallel at a predetermined interval, and is supported by inserting the cover plate portion into an insertion portion provided at equal intervals on the support member. Although you may fix to a member, it is not restricted to this.

The best mode for carrying out the present invention will be described below with reference to the drawings.
Of the drawings used in the following description, FIG. 1 is an explanatory view of a starting reaction label, (a) is a side view thereof, and (b) is a front view. FIG. 2 is a perspective view of the traffic signal cover. FIG. 3 is a plan view of a cover that is attached to the most LED side. FIG. 4 is an explanatory view of a starting reaction sign with a traffic signal cover attached, (a) is a side view thereof, and (b) is a front view. In FIGS. 1 and 4, a part of the configuration necessary for the description is shown in a transparent view using dotted lines.

The starting reaction label 1 (corresponding to the traffic light of the present invention) used in the present embodiment mainly includes a housing 10 and a flange 20.
The housing 10 is formed in a cylindrical shape, and includes support columns 11 extending in the radial direction on the side surface. The housing 10 includes a light emitting device 12 on a display side surface 10a which is one side surface 10a perpendicular to the central axis. The light emitting device 12 is formed by arranging a plurality of LEDs concentrically with the display side surface 10a, and emits orange light when lit. Further, a transparent acrylic cover 13 is attached to the display side surface 10a of the housing 10 so as to cover the light emitting device 12 formed in an arcuate cross section. The casing 10 formed in this way is hung with the free end side of the column 11 fixed to the ceiling surface of the station building so that the display side surface 10a on which the light emitting device 12 is provided faces the front to display signals. It is. The cover 13 may be made of any material as long as it is a transparent material.

  As shown in FIG. 1, the flange portion 20 is formed in a shape such that the lower half of a cylinder that is laid down so that the central axis is horizontal is cut off, and one side of the central axis faces forward. The other side is attached to the display side surface 10a of the housing 10 so that the other side faces the display side surface 10a. The rear edge 20a attached to the display side surface 10a of the flange 20 is formed in a substantially semicircular shape cut in a cross section perpendicular to the central axis of the flange 20, and the rear edge 20a. A base 21 formed in a ring shape is attached to the inner side of the frame so as to be concentric with the central axis of the flange portion 20. The base 21 is formed in such a size that an inner circumference circle can be fitted to the outer circumference of the cover 13. The flange portion 20 is fixed to the base 21. When the flange portion 20 is attached to the housing 10, the base 21 is screwed onto the display side surface 10a with the cover 13 fitted to the inner circumference of the base 21. It is fixed by stopping. At this time, the collar portion 20 is fixed to the housing 10 so as to be erected forward from the display side surface 10a extending from the right side of the light emitting device 12 to the left side through the upper portion. On the other hand, as shown in FIG. 1A, the front edge 20b of the flange 20 fixed to the housing 10 is diagonally forward from the left and right lower ends of the rear edge 20a. It is formed in the shape which inclines to. When the flange portion 20 configured in this way is attached to the housing 10, it is possible to prevent light from entering the light emitting device 12 from a predetermined angle diagonally left front and right front.

Next, the traffic signal cover 5 used in this embodiment will be described.
As shown in FIG. 2, the traffic signal cover 5 is provided with a pair of support members 50 arranged in parallel so that the plate surfaces face each other at a predetermined interval, and one end side of the support member 50. While connecting the member 50, it is formed in the connection member 51 (equivalent to the fixing part of this invention) formed in the circular arc shape along the base 21, and the other end side of each indication member 50, and the front of the collar part 20 A hooking portion 52 that can be hooked on the side tip is formed. The support member 50 is formed to have such a length that the connecting member 51 comes into contact with the base 21 below the light emitting device 12 when the hook portion 52 is hooked on the tip of the flange portion 20 (see FIG. 4A). Furthermore, the insertion part 53 which is a cutting | disconnection perpendicular | vertical to the length direction of the supporting member 50 is provided for every predetermined equal interval. A cover 60 is inserted into each insertion portion 53 and fixed to the support member 50. Among the covering portions 60, the one 60a closest to the insertion portion 53 is simply formed in a plate shape, but the other portions 60b to 60e inserted into the other insertion portions 53 are formed in a plate shape. At the same time, punch holes having a diameter of 3 mm are formed on the plate surface in the form of about 8 dots per 1 cm ² . In addition, among the cover portions 60 in which the punch holes are formed, the one 60e most from the connecting member 51 is not attached to the cover 13 when attached to the collar portion 20, as shown in FIG. The part is cut out in an arc shape.

  When the hooking portion 52 of the traffic signal cover 5 formed in this way is hooked on the tip of the flange portion 20 and the connecting member 51 is fixed to the display side surface 10a via the base 21, as shown in FIG. The surface is installed to be inclined obliquely forward and downward in the heel part 20. In addition, when the traffic signal cover 5 is attached to the flange portion 20 in this way, the cover portion 60 is arranged in parallel with the front obliquely upward. Further, when the traffic light cover 12 is attached to the starting reaction indicator 1, when the light emitting device 12 is viewed from the front along the optical axis of the light emitting device 12, the light emitting device 12 is covered by the respective cover portions 60. A size, an interval of the insertion portion 53, and the like are configured.

The use of the starting reaction marker 1 with the traffic signal cover 5 configured as described above has the following effects.
First, when this starting reaction label 1 is used, a false display (phantom) is prevented by experiment, so that the blinking of the light emitting device 12 can be surely visually confirmed. As described above, the reason why the blinking can be visually recognized is that, even if sunlight is inserted into the light emitting device 12, the sunlight is cut at a portion other than the hole portion of the cover 60, and a pseudo display can be caused. It is conceivable that the brightness cannot be obtained when the brightness is added to the light emitting device 12.

  When this starting reaction label 1 is used, the front of the light emitting device 12 is covered with the cover 60, so that iron powder is difficult to reach the light emitting device 12. Therefore, even if iron powder adheres to the light emitting device 12, the amount of light emitted from the light emitting device 12 does not decrease. Further, the starting reaction marker 1 is often seen looking up from below, but since the plate surface of the cover 60 is attached to the support member 50 so as to be inclined obliquely forward and downward, the cover 60 is obstructed. Instead, the blinking of the light emitting device 12 can be confirmed.

  In this starting reaction label 1, holes are formed in the cover parts 60b to 60e other than the cover part 60a arranged on the most front side, and no hole part is formed on the cover part 60a on the most front side. Therefore, since it becomes difficult for sunlight to enter the light emitting device 12 as compared with the case of the collar unit 20 alone, it is possible to prevent the pseudo display more reliably.

  The traffic signal cover 5 used in the starting reaction sign 1 can prevent the false indication as described above by simply attaching it to a general traffic light. Further, since the signal cover 5 is configured to be removable, when the starting reaction sign 1 is replaced, it can be reused by removing the signal cover 5 from the old signal signal and attaching it to the new starting reaction sign 1. .

  When the traffic signal cover 5 is fixed to the collar part 20, the connecting member 51 may be fixed to the display side surface 10a with a screw after the insertion part 53 is hooked on the tip of the collar part 20. On the other hand, when removing, the screw can be easily removed by removing the connecting member 51 from the display side surface 10a and pulling it forward.

  As shown in FIG. 4 (a), the traffic signal cover 5 is covered with the support member 50 even when the starting reaction sign 1 is viewed from the left and right sides, so that the portion that is not covered with the collar portion 20 is also covered. Effectively, the pseudo display can be prevented.

  Although one embodiment of the present invention has been described above, the present invention is not limited to this embodiment, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention.

For example, in the above embodiment, the hole formed with the cover 60 has a diameter of 3 mm, but preferably has a diameter of 1 mm to 3 mm.
In the above-described embodiment, the cover 60 is attached to the flange 20 using the support member 50 or the like, but it is needless to say that the cover 60 may be directly fixed to the flange 20 and attached.

  In the above embodiment, an example of application to a starting reaction sign used in a station building has been described, but it is needless to say that a traffic signal cover may be attached to a general traffic signal instructing the progress or stop of a train or a car.

  The departure reaction sign is provided when it is difficult to see the departure signal from the station manager or the conductor when starting the train. The signal display of the departure signal is displayed by blinking one white light day and night. To do.
