Description

Multifunctional elastic bollard {Multifunctional elastic bollard}

The present invention relates to a multifunctional elastic bollard, and more specifically, to ensure the safety and pass of the pedestrians, to prevent the entry of the vehicle, and to act as a buffer to absorb the impact when the collision with the vehicle, the entry of the vehicle, etc. The present invention relates to a multifunctional elastic bollard that is easy to be dismantled and reinstalled when it should be allowed, and at the same time easy to maintain when damaged by a vehicle shock.

In general, a bollard is installed between a sidewalk and a roadway to protect a pedestrian by preventing a vehicle driving on a roadside indiscriminately from entering a sidewalk, or by controlling a vehicle's entry into a specific section to control a vehicle's direction of travel. It is installed on the entrance road of a specific road so that it can be used as a guide sign for guiding lights.

Conventional bollard is formed of a stone, concrete, or metal material integrally embedded in the ground of the post of approximately round or square pillar shape is fixed to the ground through a fastening means such as mortar construction or anchor. However, such a conventional bollard has caused frequent safety accidents and safety injuries of pedestrians, and has been pointed out as a horror in the urban landscape being designed.

In recent years, bollards are also widely used to absorb external shocks such as collisions with pedestrians to protect pedestrians and to prevent damage to vehicle collisions.

In addition, the conventional fixed-type bollard is difficult to disassemble the lower base embedded in the ground in case of emergency due to fire or natural disaster, it is difficult to put the working vehicle into the area where an accident or situation occurred. The problem that the suppression of an accident or a situation is delayed is pointed out.

The present invention has been made in view of the above-mentioned problems, the purpose of which is to ensure the safety and the right of passage of pedestrians, to prevent the entry of the vehicle, and to act as a buffer to absorb the shock when the collision with the vehicle, the entry of the vehicle It is to provide a multifunctional elastic bollard that can be easily dismantled, buried, reinstalled, etc., and also easy to maintain in case of damage caused by a vehicle impact.

A feature of the present invention for achieving the above object is, in the bollard (1) for controlling the entry of the vehicle, the outer shell 11 of the elastic material is formed on the outer side of the cylindrical first pipe (10), the first A first disc 12 having a flow hole 12a is formed at an inner lower end of the pipe 10, a conical spring 13 is mounted on the first disc 12, and the first pipe 10 is The lower end is formed by sandwiching the upper portion of the rubber member 14, the spring 13, the first disc 12, the buffer member 14 is the bolt 16, the second disc 15, the nut 17 The second pipe 20 to which the first pipe 10 to which the outer shell 11 is coated is embedded, is fixedly embedded by concrete pouring, and has an inlet hole in the upper portion of the second pipe 20. A fixing disc 21 having a 21a formed thereon and a fixing nut 23 attached thereto is fixed by anchor bolt nuts 22a and 22b, and the outer shell 21a of the fixing plate 21 is inserted into the outer shell 21a. 11 coated The first pipe 10 is fitted, and the fixing disc 21, the buffer member 14, and the second disc 15 are screwed to the fixing nut 23 with the fixing bolt 24 to coat the outer shell 11. It can be achieved by a multifunctional elastic bollard, characterized in that the first pipe 10 is configured to be detachable.

The present invention as described above, the case of ensuring the safety of the pedestrians and the right to pass, prevent the entry of the vehicle, the shock absorbing effect that can absorb the impact when the collision with the vehicle, the entry of the vehicle, etc. Dismantling, reclamation, re-installation, etc., and at the same time has an effect that facilitates maintenance when damaged by vehicle impact.

Hereinafter, described in detail by the accompanying drawings a preferred embodiment for achieving the above object is as follows.

As shown in FIGS. 1 to 4, the present invention constitutes a bollard 1 with a first pipe 10 coated with an outer shell 11 and a second pipe 20 buried by concrete pouring.

The outer shell 11 coated on the outer side of the first pipe 10 is formed of an elastic material to prevent safety accidents due to the elasticity of the outer shell 11 when a pedestrian or the like strikes the bollard 1.

An inner lower end of the first pipe 10 is formed such that the first disc 12 having the flow hole 12a is coupled to the first pipe 10 by welding or the like.

The conical spring 13 is fixedly mounted on the upper portion of the first disc 12 by a bolt 16 or the like described later.

A lower end of the first pipe 10 is formed by fitting an upper portion of the buffer member 14 of rubber material.

The spring 13, the first disc 12, and the shock absorbing member 14 are inserted through the bolt 16 into which the washer 18 is inserted, and the lower part of the shock absorbing member 14 through which the bolt 16 penetrates. The second disc 15 is fitted and fixed with the nut 17.

A handle 19 is formed on an upper portion of the first pipe 10 on which the shell 11 is coated.

The second pipe 20 is formed to have a size and a depth in which the entirety of the first pipe 10 coated with the shell 11 can be embedded, and fixes the second pipe 20 by embedding concrete. .

An inner hole 21a is formed in the upper portion of the second pipe 20 and the fixing disk 21 having the fixing nut 23 attached thereto is fixed to the anchor bolt nuts 22a and 22b.

The first pipe 10 having the outer shell 11 coated therein is inserted into the inlet hole 21a of the fixing disc 21 to fix the fixing plate 21, the buffer member 14, and the second disc 15 to the fixing bolt. The first pipe 10 on which the fixing disc 21 and the outer shell 11 are coated by the fixing bolt 24 and the fixing nut 23 is fixed to the fixing nut 23 by screwing. Configure detachably.

Reference numeral 15a denotes an elastic protrusion.

Referring to the operation and effect of the bollard according to the invention of the above configuration as follows.

First, when installing the bollard (1) of the present invention is to embed the second pipe (20) in the position to install the bollard (1) by embedding the concrete.

When anchoring the concrete is to bury the anchor bolt (22a) to fix the fixing plate (21).

The first pipe 10 having the outer shell 11 coated on the inner side of the buried second pipe 20 is embedded therein, and the fixing bolt 21 is fixed to the upper end of the second pipe 20 by anchor bolt nuts 22a ( 22b) and hold the handle 19 of the first pipe 10 coated with the outer shell 11 embedded inside the second pipe 20 to raise the first pipe 10 coated with the outer shell 11. After screwing the fixing disk 21 and the buffer member 14 and the second disk 15 with the fixing bolt 24 and the fixing nut 23 is the bollard (1) is completed installation.

When an impact is applied to the installed bollard 1 by a vehicle or the like, the bolt 16 is inclined as shown in FIG. 4 by the elasticity of the shock absorbing member 14 and the flow hole 12a of the first disc 12. One pipe 10 is inclined to one side to absorb the impact applied.

Then, when the impact applied is eliminated, the first pipe 10 is restored to its original position by the elasticity of the spring 13 and the buffer member 14.

In addition, when the entry of the vehicle should be allowed, the fixing bolt 24 and the fixing nut 23 are loosened, and the first pipe 10 coated with the outer shell 11 as shown in FIG. 3 is connected to the second pipe 20. By descending to the inside, it is possible to allow entry of the vehicle.

  On the other hand, when it is necessary to replace the bollard (1) damaged by the impact of the vehicle, etc. by loosening the anchor bolt nuts (22a, 22b) and replace only the first pipe (10) coated with the outer shell 11, It is easy to maintain.

Although the preferred embodiments of the present invention have been illustrated and described above, the present invention is not limited to the above-described embodiments, and the present invention is not limited to the above-described embodiments without departing from the spirit of the present invention as claimed in the claims. Various modifications can be made by those skilled in the art, and such modifications are intended to fall within the scope of the appended claims.
