BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a track reflector.

[0002]

2. Description of the Related Art Track reflectors are installed before and after a railroad crossing or before and after a track turnout, and have the function of reflecting the headlight light of a train and indicating to a driver the target stop position of the train. . . Explaining the conventional orbital reflector,
The outer shape is formed in a triangular tube shape using a metal material such as iron,
Each wall is formed on the base, the reflector, and the support, respectively.

[0003] Each component will be further described in detail together with its function. The base portion is to be attached to a sleeper or the like and is provided with attachment holes for screws and nails. The reflecting portion has a reflecting member (a reflecting plate made of synthetic resin or glass having a diamond-cut or lens-cut pattern on its surface) attached to the outer surface of the wall portion. In some cases, a reflective paint may be applied to the outer surface of the wall to form a reflector. With this configuration, the reflector has a function of reflecting the headlight light of the train and indicating the stop position to the train driver. The support part supports the reflection part at a predetermined angle with respect to the base part.

[0004]

However, since the above-mentioned track reflector is formed by using a metal material, for example, when the rail is replaced or when the track variations are matched, the replacement rail and the construction work are performed. When it is dented or damaged by a heavy object such as a tool, it will not restore its original shape and will no longer function as a reflector, so it must be replaced. Further, since it is made of metal, there is a problem in that it is exposed to wind and rain for a long time to cause rust, which lowers durability. Therefore, the present invention has been made to solve the above problems, and an object of the present invention is to provide a orbital reflection plate that can be restored even when deformed by an impact by a heavy object such as a construction tool and does not rust. It is in.

[0005]

The present invention has the following constitution in order to achieve the above object. That is, it has a cylindrical outer shape, and a part of the peripheral surface is formed on a base part attached to a sleeper or the like, and a part of the peripheral surface following the base part is attached to the outer surface with a reflecting member and the base part is formed. An orbital reflector plate formed on a reflecting portion that is provided so as to be undulated in the direction of the base portion, and a part of the peripheral surface is formed on a supporting portion that supports the reflecting portion at a predetermined angle with respect to the base portion. It is characterized in that at least the support portion is formed by using an elastic material such as rubber. Further, the base portion and the reflection portion may be integrally formed with the support portion using an elastic material such as rubber. Furthermore, the wall thickness of the support portion is better to be thinner than the wall thickness of the reflection portion, or the support portion may be formed with a thin portion in a direction perpendicular to the circumferential direction.

[0006]

The part of the peripheral surface continuing to the base part is formed on the outer surface on which the reflecting member is attached, and the part is formed so that it can be undulated in the direction of the base part. Since it is formed on the support part using an elastic material such as rubber that supports the base part at a predetermined angle, when the external force is applied to the reflection part, the support part elastically deforms and the reflection part is When the external force is lost, the reflective unit rises to a predetermined angle due to the elastic force of the support unit. Further, even if the base portion and the reflecting portion are integrally formed with the supporting portion by using an elastic material such as rubber, the same effect can be obtained, and the manufacturing can be further facilitated. In addition, the wall thickness of the support part,
If the wall thickness of the reflector is thinner than that of the reflector, or if a thin portion is formed on the support in a direction perpendicular to the circumferential direction, the support will be elastically deformed when an external force is applied to the reflector, and the force applied to the reflector Can be absorbed more reliably.

Explaining each component in more detail, the base portion 14 is provided with mounting holes 22 for screws and nails for mounting on the sleeper 12 or the like. The portion where the mounting hole 22 is provided is slightly extended in a direction perpendicular to the circumferential direction (both ends of the orbit reflector 10) so that screwing or nailing work from above can be easily performed. Has been formed. The reflecting portion 18 has a reflecting member (a reflecting plate made of synthetic resin or glass having a diamond cut or lens cut pattern on its surface) 16 attached to the outer surface of the wall portion. Also,
As in the present embodiment, as an example of the reflection member 16, a reflection paint may be applied to the outer surface of the wall to form a reflection plate, or a synthetic resin material such as rubber containing reflection paint may be used as the base. It may be formed integrally with the portion 14, the reflecting portion 18, and the supporting portion 20. With this configuration, the reflection unit 1
8 can reflect the headlight light of the train to show the stop position to the train driver.

The supporting portion 20 supports the reflecting portion 18 with respect to the base portion 14 at a predetermined angle. Moreover, the support part 2

The thin portion 24 prevents the coating material from dripping toward the support portion 20 when the reflective coating material is applied to the reflective portion 18, and makes it easier for the support portion 20 to be applied when an external force is applied to the track reflector 10. It is provided to allow it to bend. Note that the wall thickness of the support portion 20 may be made thinner than the wall thickness of the reflection portion 18 so that the support portion 20 can be easily bent.

Next, the method of installation will be described. A screw or a nail is used to fix the reflecting portion 18 to the sleeper 12 or the like at a position close to the track so that the reflecting portion 18 faces the traveling direction B of the train. As described above, with the above configuration, the reflecting member provided in the reflecting portion 18 can reflect the headlight light of the train and can temporarily indicate the stop position to the driver. Further, after once installed, even when heavy objects such as replacement rails and construction tools come into contact with the track reflector 10 during construction such as rail replacement or track ballast alignment, the support portion 20 elastically deforms. Since the reflecting portion 18 bends and falls on the base portion 14 to absorb an external force, it is possible to reduce damage to the orbiting reflection plate 10. Further, when the external force disappears, the elastic force of the supporting portion 20 causes the reflecting portion 18 to stand up to a predetermined angle, so that the orbiting reflector plate 10 is formed.
The function as can be restored. Further, the supporting portion 20 is the reflecting portion 1
Since it is easier to bend than 8, the reflecting portion 18 does not bend when an external force is applied to the orbiting reflector plate 10, and the reflecting member 16
The damage of can be avoided. Furthermore, compared with the conventional example, since no metal material is used, rust does not occur and it is highly durable and also has heat retention, so that snow is unlikely to adhere in winter.

The base portion 14, the reflecting portion 18, and the supporting portion 2 are also provided.
0 is integrally molded using a synthetic resin material such as rubber or the like, a metal material is used for the base portion 14 and the reflection portion 18 as in the conventional orbital reflection plate, and the reflection portion 18 is used for the base portion 14.

Is formed on the base portion 14 attached to the sleeper 12 or the like. Further, a part of the peripheral surface following the base portion 14 (two wall surfaces following the base portion 14 in this embodiment) is formed in the reflecting portion 18. The reflecting member 16 is attached to the outer surface of the wall surface which is in contact with the base portion 14, and the wall surface is provided so as to be capable of undulating in the direction of the base portion 14. With this configuration, even if a heavy object such as a replacement rail or a construction tool comes into contact with the track reflection plate 10, the support portion 20 is elastically deformed and bent, and the reflection portion 1
8 falls on the base portion 14 and absorbs the external force, so that the orbital reflector 10 can be prevented from being damaged. Further, when the external force disappears, the elastic force of the supporting portion 20 causes the reflecting portion 18 to stand up to a predetermined angle so that the function as the orbiting reflector plate 10 can be restored.

[0017]

When the orbital reflector according to the present invention is used,
A part of the peripheral surface continuing to the base part is formed in a reflective part that is provided with a reflecting member attached to the outer surface and is capable of undulating in the direction of the base part. Furthermore, a part of the peripheral surface forms the reflective part in the base part. Since it is formed on the support part using an elastic material such as rubber that supports at a predetermined angle with respect to, the support part elastically deforms when an external force is applied to the reflection part, and the reflection part is on the base part. Since it falls over to absorb external force, the reflective part is less likely to be damaged and durability is improved. Further, when the external force disappears, the elastic force of the supporting portion causes the reflecting portion to stand up to a predetermined angle, so that it can function again as a reflecting plate. In addition, if the base part and the reflection part are integrally formed with the support part by using an elastic material such as rubber, the manufacturing can be further facilitated, the manufacturing cost can be reduced, and the metal material is used as in the conventional example. Since it does not exist, rust does not occur and durability is further improved. In addition, since it has a good heat retaining property and snow is less likely to adhere in the winter, it is possible to prevent a decrease in the reflection ability. Also,
If the wall thickness of the support part is made thinner than the wall thickness of the reflection part, or if the thin part is formed in the support part in the direction perpendicular to the circumferential direction, the support part will surely elastically deform when an external force is applied to the reflection part. However, the remarkable effect that the force applied to the reflecting portion can be more surely absorbed.
