BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an improvement of a traffic light suspension device used for mounting a traffic light, particularly a pedestrian traffic light.

[0002]

2. Description of the Related Art Numerous traffic lights are installed on roads to protect automobiles and pedestrians from traffic accidents and to ensure traffic safety. Conventional types of mounting a traffic light include a stand type mounting the traffic light on the upper end of the signpost and a side pole type mounting the upper and lower parts of the traffic light on two arms fixed horizontally to the side pole. However, recently, as a means for installing a pedestrian traffic light, a method of suspending the traffic light has been frequently adopted.

As shown in FIG. 7 (Japanese Utility Model Publication No. 4-2194), this type of signal hanging apparatus has a signal 40 attached to a lower part and a male screw part 41a provided to an upper part. There is known a device in which a supporting shaft 41 is passed through an arm 42 and a lock nut 43 is screwed into a male screw portion 41a on the upper portion of the supporting shaft 41 so that the lock nut 43 is not loosened.

[0004]

In the above-mentioned traffic light hanging device, since the traffic light is mounted on and supported by the support shaft, the stress applied to the front, rear, left and right of the traffic light is determined by the strength of the support shaft. It is necessary to deal with it, but if stress such as wind pressure is constantly applied to this support shaft, the support shaft will fatigue over time, the strength to support the traffic signal will decrease, and the traffic signal will drop This can cause the situation. In addition, when the height of the traffic light is relatively low, such as a pedestrian traffic light, a tall vehicle such as a truck or a wagon-type vehicle may come into contact with the traffic light. There is also a possibility that the supporting spindle is bent or broken and the traffic light falls.

[0010]

[Operation and effect of the present invention] In the traffic light suspension device of the present invention, the upper cylinder and the lower cylinder constituting the cylindrical main body are ball-mounted.
It can be connected by a joint or the lower and lower parts of the upper cylinder
By making contact with the upper end of the cylinder and connecting,
Since the tubular body is provided with the tiltable portion, when a stress such as wind pressure is applied from the front, rear, left and right of the traffic light, the traffic light can be flexibly tilted to absorb the stress applied to the tubular body. As a result, the support shaft does not bend or break unlike conventional tiltable ones, and the support shaft can be prevented from being fatigued by receiving stress for many years. It is unlikely that a drop will cause a traffic light to fall.

[0011] In particular, when the height of the traffic light is relatively low, such as a traffic light for a pedestrian, even if a tall vehicle such as a truck or a wagon-type vehicle comes into contact with the traffic light, the cylindrical main body is not affected. Can be tilted, so that not only breakage of the suspension device for the traffic light, etc., but also impact on the traffic light main body and the vehicle main body can be reduced.

Further, in the case where the elastic member is disposed all around the tiltable portion of the cylindrical main body for suspending the traffic light, or is disposed at equal intervals at at least three positions of the tiltable portion, This elastic member can absorb the stress that the traffic signal receives from front, rear, left and right, so it can not only prevent the traffic signal from tilting excessively due to shock or stress, but also prevent the tilt and vibration from continuing, and it is stable The traffic light can be kept in a drooping state. In addition, the support of the traffic can be carried out in elastic member. in this case,
When the upper cylinder and the lower cylinder are connected with a ball joint
The effect of reinforcing the support of the traffic signal by the tubular body is obtained,
When the cylinder and the lower cylinder are connected by contact, the signal
The function as the lasting is obtained. In addition, if the elastic member is divided and formed, the material can be reduced , and also, even if one elastic member is broken, the traffic light can still be sufficiently supported by the other remaining elastic members.

Here, the elastic member is disposed so as to be inclined so as to approach the center line of the cylindrical main body from the upper part to the lower part, and the elastic member is provided vertically and vertically. Comparing the magnitude of the stress component applied in the length direction of the elastic member and the magnitude of the stress component applied in the bending direction of the elastic member when receiving wind pressure or the like from the direction, the one in which the elastic member is provided like the former is better. The stress component applied in the length direction of the elastic member is larger than that provided as the latter, while the stress component applied in the bending direction of the elastic member is smaller. Therefore, if the elastic member is arranged so as to approach the center line of the tubular main body from the upper part to the lower part as in the present invention, the elastic member is bent when the traffic signal is subjected to pressure from front and rear and right and left directions. Since the stress component applied in the direction can be reduced, the signal can be kept in a stable state without vibrating if the wind speed is about 20 m. In addition, when the traffic light is vibrating, the vibration can be stopped immediately.

In the case where the cylindrical body is divided into an upper cylinder and a lower cylinder, and both cylinders are connected by a ball joint, the cylindrical body is formed of a rigid material, so that the mechanical strength is excellent. However, it also has the flexibility that the lower cylinder can be freely tilted by the stress applied to the traffic light.

FIG. 2 is a front view of a traffic light hanging apparatus according to an embodiment of the present invention, FIG. 2 is a top view of the same, FIG. 3 is a bottom view of the same, and FIG.
Is a plane including a vertical center line (A-A in FIG. 2).
FIG. 2 is a cross-sectional view cut in a diagonal direction as viewed from FIG.

The signal hanging apparatus according to this embodiment has a female screw portion formed inside the upper end of the upper cylinder 11 of the cylindrical main body 10.
11a can be fixed to the male screw portion attached to the power supply support member (equivalent to the fixed part of the present invention) (not a shown), and traffic (not such shown) is attached to the lower end of the lower cylinder 12 traffic lights mounting plate 13 so that the can be attached by engaging the three holes 13a drilled in (equivalent to the mounting portion of the present invention). The electric wire 30 is inserted through the through-hole inside the cylindrical main body 10, and electric power is supplied from the power supply support member to the traffic light. Upper cylinder 11 and lower cylinder 1
2 and is connected by a ball joint 14 (<br/> phase tiltable part of the present invention those) traffic, as can traffic moves in the ball joint 14 when the applied pressure It is configured.

Each of the upper cylinder 11 and the lower cylinder 12 has a protection.
Vibration rubber mounting plate and is (elastic member mounting plate) 15 and 16 attached, (<br/> phase to the elastic member of the present invention those) four anti Fugo arm 17 at equal intervals, the upper and lower ends thereof It is fixed by attaching tighten the fixation with bolts with nuts 18, 19. Here, the respective vibration-isolating rubber mounting plates 15 and 16 are angled so as to extend in parallel from the central portion contacting the upper cylinder 11 and the lower cylinder 12 toward the outer periphery and downward, and accordingly, the parallel anti- parallel members. The anti-vibration rubber 17 fixed to the vibration- absorbing rubber mounting plates 15 and 16 is arranged at an angle of about 5 degrees so as to approach the center line of the cylindrical main body from the upper part to the lower part.

When a signal such as a wind pressure is applied from the front, rear, left and right sides of the traffic signal by configuring the traffic signal hanging apparatus in this manner, as shown in FIG. Tilts to absorb the stress applied to the traffic light hanging device. for that reason,
Because the support shaft does not bend or break like conventional ones that cannot be tilted, and because the support shaft can be prevented from fatigue due to receiving stress for many years, the strength of supporting the traffic light is reduced. It is unlikely that a traffic light will fall.

In particular, when the height of the traffic light is relatively low, such as a traffic light for a pedestrian, even if a tall vehicle such as a truck or a wagon-type vehicle comes in contact with the traffic light, the cylindrical main body is not affected. Can be tilted, so that not only breakage of the suspension device for the traffic light, etc., but also impact on the traffic light main body and the vehicle main body can be reduced.

Further, the vibration isolating rubber 17 is connected to the ball joint 14.
Are arranged at equal intervals in four places around the vehicle, so that the stress received by the traffic signal from front, rear, left and right can be absorbed by the anti-vibration rubber 17, and the traffic signal can be tilted excessively by impact or stress, and the tilt and vibration can be maintained Can be prevented, and the traffic light can be kept in a stable hanging state. Then, as the vibration isolating rubber 17 moves from the upper part to the lower part, the cylindrical body 10
Is arranged at an angle of about 5 degrees so as to approach the center line of the vibration-proof rubber 17, the stress component applied in the length direction of the vibration-proof rubber 17 is large, while the stress component applied in the bending direction of the vibration-proof rubber 17 is small, and Can be maintained in a stable state without vibration if the wind pressure is about 20 m. Further, when the traffic light is vibrating, the vibration can be stopped immediately.

In the above embodiment, since the tiltable portion of the tubular main body 10 of the signal hanging apparatus is formed by the ball joint 14, the members constituting the cylindrical main body 10 are made of a rigid material, and have a high mechanical strength. It is preferred because it is excellent,
A part of the tubular main body may be made of a flexible member such as rubber or a spring having high strength to be a tiltable portion. When the elastic member provided around the cylindrical main body has a sufficient signal support strength, rubber or a spring having less strength can be used for the tiltable portion.

Further, in the above embodiment, the vibration isolating rubber 17 is used as the elastic member. However, a conventionally known elastic body such as a spring can be used. For example, an elastic member of a type in which a spring 21 is inserted into a cylindrical rubber 20 as shown in FIG. 6 may be used. In FIG. 6, the upper cylinder 22 and the lower cylinder 23 are composed of two dividable cylinders. When the traffic light is pushed in one direction, the elastic member is compressed and at the same time the inclination direction is reduced. Two cylinders on opposite sides
It is configured such that the contact portions 24 can be separated from each other.

The number of the elastic members is not limited to four, but can be appropriately increased or decreased in consideration of simplification of manufacturing, reduction of materials used, weight reduction, reinforcing effect of signal support, and the like. The elastic member may not be divided into a plurality of parts, but may be a single vibration-proof rubber surrounding the entire periphery of the tiltable portion. However, it is preferable to provide at least three of them so as to be able to oppose the pressure applied from the front, rear, left and right directions of the traffic light.
