Moreover, the case covering a bollard main body is separated into a first case and a second case to be installed in order to enable the case to easily be replaced when the case covering the bollard body is damaged by an external impact.

Description

Bollard {Bollard}

The present invention relates to a bollard, and more particularly, to a bollard, which includes pedestrians, pedestrians, pedestrians, pedestrians, bicycle roads, large marts, It is about a bollard that prevents an accident.

Generally, a bollard is an obstacle installed to prevent a vehicle from entering the road or grass for pedestrians. It is usually made of iron columnar or concrete. The entrance of the bollard, which is divided into pedestrians, Or the center line of the roadway to prevent the entry of the vehicle and the invasion of the center line, thereby ensuring the pedestrian's passage and safety, and preventing the center line from being invaded in advance.

Generally, such bollard is manufactured by processing stone such as marble or granite, concrete, steel or the like having high strength so that it is not easily broken by external force.

Recently, a bollard with elastic restoring force or shock absorbing function is installed close to India to protect pedestrians.

The bollard is provided with an elastic means therein to protect the pedestrian by shock absorbing and restoring force. In the state where the restoring force of the elastic means is lowered due to continuous external impact, that is, the bollard is tilted excessively, It is not possible to secure the safety of the pedestrian because it can not prevent the accident and the entry of the vehicle.

In addition, the outer case of the conventional bollard is integrally formed, which is not easy to replace when the outer case is broken by an external impact.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art by providing an elastic body formed of a urethane rubber material in a bollard and elastic means formed by providing an upper plate and a lower plate on the upper and lower sides of the elastic body, The outer case which is enclosed by the bollard body is detached and coupled to the outer case, so that the outer case which is damaged when the outer case is impacted To provide a bollard that can be replaced.

In order to achieve the above object,

An elastic member which is positioned and coupled between the upper body and the lower body, and a case which surrounds the outer peripheral surface of the upper body and the lower body .

The elastic means may include an upper plate having a coupling hole for coupling with the lower inner periphery of the upper body, a lower plate having a coupling hole for coupling with the inner periphery of the lower body, and an elastic body formed organically on the upper plate and the lower plate.

The elastic means includes a lower plate on which a coupling hole for coupling with the inner periphery of the lower body is formed, a lower plate on which a coupling hole for coupling with the inner periphery of the lower body is formed, an elastic body formed on the upper and lower plates, .

Further, a flow groove is formed on the outer circumferential surface of the elastic body.

The upper plate further includes a first upper plate having a first coupling hole formed in close contact with an inner periphery of a lower body of the upper body and a second upper plate having a second coupling hole closely engaged with the upper body bottom, And a second lower plate having a second engaging hole formed in close contact with the upper surface of the lower body.

The inner diameter of each of the first coupling holes may be smaller than the inner diameter of each of the second coupling holes.

The case may further include a first case having a fixing part formed on an outer periphery of the upper body and the lower body to surround the outer periphery, and a second case having an upper outer circumferential surface close to the first case and being seated on the fixing part .

As described above, the present invention is characterized in that an upper plate and a lower plate are formed on upper and lower sides of an elastic body made of urethane, respectively, and the upper plate and the lower plate are formed with a coupling hole at a central portion thereof to organically form a buffering effect and elasticity Thereby preventing a safety accident of the pedestrian and certainly preventing entry of the vehicle.

Further, by incorporating a compression spring in the inside of the elastic body, there is an effect of providing an excellent elastic force that can be quickly restored after the bollard has flowed into 10 [deg.] To 20 [deg.] Upon collision.

In addition, since the case covering the bollard body is provided separately from the first case and the second case, there is an effect that the case covering the bollard body can be easily replaced when the case is damaged by an external impact.
