The signal display lamp 131 is preferably installed at the upper end of the main body 120 so as to easily recognize the light emitted from the outside, the light source selectively emits red and green light, and consumes little power and power. LEDs having excellent control characteristics may be used, and a plurality of LEDs may be spaced apart at regular intervals.

The switch 132 may be provided on one side of the main body 120 or on the PC globe 134. When the switch 132 is turned on by a pedestrian's switching operation, a signal is applied to the control unit 133 connected thereto. The signal display lamp 131 is configured to turn on or flash at a time interval.

Referring to FIG. 5, the signal indicator 131 is always lit by a red light, which is a pedestrian crossing stop and a vehicle traffic signal, and the pedestrian presses the switch 132 so that the switch 132 is turned on ( ON), the red light blinks (flashes) during the first set time (5 seconds), and after the first set time has elapsed, the pedestrian crossing is allowed for the second set time (20 seconds) and the vehicle stop signal. Phosphorus green light turns on, and after the second set time elapses, the green light blinks for a third set time (5 seconds), and after the third set time elapses, the red light is always restored to the lit state of the red light again. Controlled.

Here, the first set time is a time for notifying the vehicle driver that the pedestrian is waiting for crossing before crossing the crosswalk, the second set time is sufficient time for the pedestrian to cross the crosswalk, and the third set time is the crosswalk. In this embodiment, the first to third set times are set to 5 seconds, 20 seconds, and 5 seconds, respectively, but the present invention is not limited thereto. Of course, each setting time may be set differently in consideration of road conditions and traffic volume, such as distance.

The PC glove 134 is coupled to an upper end of the main body 120 so as to cover an upper circumference of the signal display 130, and the light emitted from the signal display lamp 131 composed of LEDs having a linearity is connected to the PC glove ( As it passes through 134, it is refracted and diffused at various angles, thereby providing an opportunity for pedestrians as well as vehicle drivers to easily recognize the signal state of the crosswalk. In addition, the PC glove 143 is not only easily damaged from an external impact due to its material property, and has the advantage that the appearance of the bollard 100 can be beautifully configured.

The floodlight 140 is configured to easily recognize the presence or absence of pedestrians crossing the crosswalk by irradiating light toward the crosswalk at night, a plurality of floodlights connected to the power cable 150 141 is disposed vertically spaced apart from the left and right, and the horizontally spaced between the light emitting lamps 141 is installed in the transverse direction to transmit the light of the light emitting lamp 141 to one side of the main body 120, the light transmission slit 144 Reflecting plate 142 reflecting toward the crosswalk by passing through) is provided.

In this case, the reflector plate 142 disposed up and down so that the light emitted from the light emitter 140 brightens the entire pedestrian crossing may be arranged to reflect light at different angles.

In addition, it is preferable that the floodlight 141 uses an LED light source having excellent straightness so that light can be irradiated to a pedestrian crossing at a long distance.

The floodlight 140 is used to illuminate a pedestrian crossing at night, and thus, it is not necessary to illuminate the pedestrian crossing at daytime, so that the light projector 140 is turned on at night and is turned off at daytime. As an embodiment for controlling the lighting of the light emitter 140 as described above, the light emitter 140 may be configured to be turned on only during the set time of the night by the timer 143 and to be turned off for the other time.

In another embodiment for controlling the lighting of the transmitter 140, an optical sensor (not shown) for detecting the illuminance of the light in the projector 140 and a switching (ON / OFF) operation according to a signal according to the detected light intensity Is provided with an optical switch (not shown), when light below a certain illuminance (Lux) is detected by the optical sensor, the optical switch is turned on (ON) and the power is supplied to the floodlight lamp 141 is turned on, When light exceeding the illuminance is detected by the optical sensor, the optical switch may be configured to be turned off and the power supply is cut off so that the floodlight lamp 141 is turned off. In this case, the pedestrian crossing can be brightly lit not only at night, but also at daytime weather conditions, so that the vehicle operator can be alerted.

4 and 6, the shock absorbing unit 160 is configured to prevent damage to the bollard 100 and the vehicle and injuries of the pedestrian when the vehicle or the pedestrian collides with the bollard 100. An elastic member 161 provided at an inner lower portion of the 120, an upper plate 162 on which an upper end of the elastic member 161 is fixed, and an edge portion is in close contact with an inner surface of the main body 120, and an elastic member 161. The lower plate 163 is fixed and the lower plate 163 on which the lower end of the main body 120 is seated, and the upper end is fixed to the center of the upper plate 162, and a fixed bundle integrally formed at the center of the upper surface of the lower plate 163 ( The lower end is fixed to the wire 164 and the lower plate 163 is projected downward in the center of the bottom is formed integrally and consists of a male screw portion 167 formed with a thread 167a on the outer peripheral surface. The wire 164 is preferably composed of a plurality of strands in order to prepare for damage and improve durability.

Coupling between the main body 120 and the shock absorbing unit 160, by inserting the shock absorbing unit 160 to the inside of the main body 120 having a lower opening, the lower edge of the main body 120 is seated on the lower plate 163 After positioning, the upper plate 162 may be fixedly mounted to the inner side of the main body 120 using fastening means 168 such as bolts, pins or rivets. Alternatively, the configuration in which the upper plate 162 is welded to the main body 120 may be possible.

The base portion 110 coupled to the lower side of the shock absorbing portion 160 is fixed to the bottom surface of the lower plate 163 and the base top plate 111 through which the male screw portion 167 passes, and the base top plate. It includes a fastener 114 is formed integrally on the bottom surface of the 111 and the screw tab 114a is formed on the inner surface to be screwed with the male screw portion 167. In addition, the base upper plate 111 is connected to the base lower plate 112 by connecting rods 113 made of reinforcing bar material disposed at regular intervals. The base lower plate 112 may be a fastening hole 112a for fastening anchor bolts to underground structures (not shown).

The base unit 110 configured as described above is fixedly mounted in the state of placing concrete in the ground through the curing process of a predetermined time.

As described above, when the vehicle 120 or the pedestrian collides with the main body 120 by connecting the main body 120 through the shock absorbing unit 160 on the base 110, the main body 120 is in a direction in which an external force acts. When bent, the external force is restored to its original position by the elastic force of the elastic member 161.

In addition, in the present invention, the male screw portion 167 of the shock absorbing portion 160 is fastened to the fastener 114 of the base portion 110 by a screwing method, so that the main body 120 is damaged by external impact. When replacement is required, since only the damaged body 120 needs to be replaced, the maintenance of the bollard 100 is facilitated.

Hereinafter, the operation of the present invention will be described.

7 and 8 are perspective views for explaining the signal display function of the bollard according to the present invention. As illustrated in FIG. 7, the signal indicator 130 is always lit by a red light R, and the pedestrian notifies the pedestrian crossing of the pedestrian crossing and informs the driver of the vehicle of possible traffic. Therefore, the pedestrian located on the sidewalk stops crossing after seeing a red light signal, and waits until the green light turns on by pressing the switch 132.

When the red light blinks for the first set time (5 seconds) by the pedestrian's switching operation, the vehicle driver soon stops the vehicle in front of the crosswalk in anticipation that the signal state will change to the green light. After that, when the first set time elapses, the green light G is turned on for the second set time (20 seconds), so that the pedestrian crosses the crosswalk safely as shown in FIG. 8. When the second set time has elapsed, the green light blinks for the third set time (5 seconds) to inform the pedestrians who are about to cross the crosswalk soon that the green light will turn off and change to red. Be careful not to cross. After a pedestrian crosses the crosswalk safely, the pedestrian is restored to a red light and is ready for traffic.

By changing the state of the traffic light 130 at a time interval set by the switching operation of the pedestrians, the pedestrians can safely cross the pedestrian crossing, thereby greatly reducing the incidence of traffic accidents in places without traffic lights. In the absence of pedestrians, the vehicle will always be in red light and will not interfere with the smooth traffic.

9 is a perspective view for explaining the night light function of the bollard according to the present invention. When the floodlight 140 of the bollard 100 is turned on and irradiated with light toward a crosswalk in a dark environment such as at night or in cloudy weather, the entire crosswalk is brightly illuminated so that the presence of a pedestrian on the crosswalk and the crosswalk The vehicle driver can easily grasp the behavior of the pedestrian crossing the vehicle at a location far from the crosswalk. Therefore, even when the vehicle operator does not know that the traffic light 130 of the bollard 100 is in a green light state, the existence of the pedestrian walking through the crosswalk can be easily confirmed, so that the vehicle operator may see the pedestrian crossing the crosswalk. It is possible to prevent traffic accidents that can occur in an unrecognized state.

10 and 11 are operational state diagrams for explaining the shock absorbing function of the bollard according to the present invention, Figure 10 shows a normal installation state that no external shock acts on the bollard 100, Figure 11 is a bollard ( An external shock acts on the main body 100 to indicate the main body 120 is pivoted.

Referring to FIG. 10, when a vehicle collides with the main body 120 of the bollard 100, the main body 120 and the upper plate 162 coupled thereto are pivoted in a direction in which an external force acts. In this case, the lower end of the main body 120 on the side where the external force acts is spaced upward from the lower plate 163 and the main body 120 is pivoted with the lower end of the main body 120 as the center of rotation, and the main body 120 is rotated. Since the upper plate 162 and the lower plate 163 fixedly mounted are connected by the wire 164, the main body 120 is smoothly turned and at the same time the main body 120 is rotated when the main body 120 is rotated. To prevent separation from the separation. When the main body 120 rotates, the upper and lower ends of the elastic member 161 are fixed to the upper plate 162 and the lower plate 163, respectively, so that the portion of the elastic member 161 on the side where the external force is applied is relaxed. The other side of the elastic member 161 is in a compressed state.

Then, when the action of the external force is released, the elastic force to be restored to the original state to the elastic member 161, which is relaxed to one side and compressed to the other side acts on the main body 120, the main body as shown in FIG. 120 is restored to its original vertical state.

10 and 11 illustrate a case in which a vehicle collides with the bollard 100, the shock absorbing function of the bollard 100 is equally applied even when a pedestrian or other object collides with the bollard 100. .

Therefore, when a vehicle or a pedestrian collides with the bollard 100, the shock is absorbed by the shock absorbing unit 160 of the bollard 100, thereby preventing damage to the bollard 100, as well as damaging the vehicle and injuring a pedestrian. It can be prevented.
