BACKGROUND OF THE INVENTION

This invention relates to the traffic collar cone, in particular, to the self-recovering traffic collar cone that is more effective for drawing the driver's attention and thus can guarantee the safety of driving, and that is so built as to be able to get crushed when impacted and to recover its original shape after lapse of impact so that its product life span can be fully extended and the vehicle collided therewith is also kept substantially unharmed.

Generally, the traffic collar cone has been used as the indicator to let the driver recognize the changing state of traffic lane more accurately, especially at the place where the road becomes narrow in case of the road repair work or is curved.

However, the conventional traffic cone is normally made of the non-recovery materials such as rubber, polyethylene, vinyl chloride resin or the like and the reflection sheet is attached thereon so that upon the even small impacts, the collar cone or the vehicles are easily damaged. As the result of it, replacement of the traffic collar cone is frequently required and therefrom the economic loss is greatly happened.

SUMMARY OF THE INVENTION

This invention is designed to overcome the above-noted problems the conventional collar cone has.

Accordingly, one object of this invention is to provide the traffic collar cone made of materials having the great flexibility so as to recover its original shape after lapse of impact, by which the traffic collar cone is able to be kept unharmed even when collided with by a vehicle.

Another object of this invention is to provide the traffic collar cone coated with the anti-dust silicon to keep its reflection effects as it was for the long time.

Still another object of this invention is to provide the traffic collar cone with which the vehicle collided is also kept substantially unharmed.

A further object of this invention is to provide a traffic collar cone designed to draw the driver's attention as much as possible and thus guarantee safe driving.

DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

In order to attain the above-noted goals, a traffic collar cone is provided which has two portions, that is, a delineator in which a reflection sheet is attached on its upper part and a plug is placed under the sheet, having air inlet and outlet passed through upwardly and downwardly, and a body member in the form of cone in which the insertion hole is provided for receiving the plug, for causing the plug to be mounted at the upper end of the body member. A support panel is placed at the bottom end of the body member, and the collar cone is attached on the outer surface of the body member.

As built above, this collar cone has many advantages, and a more detailed description is provided below with reference to the accompanying drawings.

As shown in FIG. 1 and FIG. 6, delineator(10) has a reflection sheet(11) attached at its upper part and a supporter(14) placed underneath sheet(11) for supporting the reflection sheet(11) and the plug(12) that upholds the lower part of said reflection sheet(11) and are on the other hand mounted on the support panel, and that is provided with a circular protrusion(13) on its lower trim.

The plug(12) has the several vertical air outlets and inlets(15)

The body member(20) has an insertion hole(21) in its upper end for the plug(12) to be mounted, and a stub at its lower end for engaging with the circular protrusion(13). On the inner surface of the cone-shaped collar cone body member(20), multiple circular ribs(23) are projected inwardly The support panel(24) is placed at the bottom end of the collar cone body member(20); the support panel(24) has many pressurized air outlet grooves(28) provided therein, extending in a radial direction and in concentric circles.

Further, on the outer surface of the body member(20) are provided multiple grooves(25) that are of irregular surface(26) engraved so as to have the opposite angles, on which cone collars(27) are attached.

The inner surface of the collar cone body member(20) has flexible grooves(29) at its lower end.

Any of collar cone body member(20) and the delineator (10) are coated with diluted silicon mixed with tin origin organic materials.

It is advisable to use polyurethane having superior flexibility for making the collar cone body member(20) and plug(12) of the delineator(10).

The operation and the advantage of the traffic collar cone this invention are as follows.

Once the traffic collar cone installed on the road is collided with by a vehicle or the traffic collar cone(1) is trod on by a vehicle, the body member(20) is bent or is squeezed due to elastic power of the flexible grooves(29), simultaneously the inner air present within the cone is forced out through the air outlet and inlet(15) so that the both collar cone(1) and vehicle collided therewith are kept unharmed. Further, after the vehicle departs from the place, the traffic collar cone(1) recovers its original shape based on its self-recovery power.

That is, when traffic collar cone collided with by a vehicle, the body member of collar cone gradually recovers its original shape, based on the self-recovery power of the multiple flexible grooves(29) and the circular rib(23) formed on the inner surface of the collar cone body member(20), simultaneously with air entering into inside of the body member(20) through the air inlet and outlet(15), so that irrespective of the collision occurrence with a vehicle the collar cone can be reshaped as it was, and thereby it can be used for a long time.

Further, the upper part of the outer surface of the body member(20) is provided with several irregularly surfaced grooves(25) and therein are inserted, insert the cone collars from above of the body member. Each cone collar has both ends of a respective reflection sheet(11) adhered each other by way of a high frequency adhesion method to provide a frusto-conically tapered structure.

In this construction, the irregular surface of the body member(20) not only broadens the collar adhesive area to the body member(20) but also allows the bubbles produced from the adhesive material to go out; thereby a strong adhesion is obtained and accordingly adhesion work can be easily performed.

On the other hand, for installing the traffic cone collar cone(1) on the road, the plug(12) in the delineator(10) is previously inserted in the insertion hole(21) formed in the upper end of the body member(20).

At that time, it is required for the protrusion(13) formed on the bottom trim of plug(12) to be fully engaged against in the downwardly facing lower shoulder(22) provided in the upper end of the body member (20), and which surrounds the insertion hole(21).

After the delineator(10) has been assembled painting of adhesive materials on the ground is done and then the support panel(24) of the body member (20) is adhered on the ground (i.e. on the roadway).

At that time, since bubbles from the adhesive are exhausted through the pressurized air outlet(28) so that collar cone body member(20) is strongly adhered on the ground.

Any of all the components such as the delineator(10), collar cone body member(20) and reflection sheet(11) are coated with coating materials to prevent dust, or pollution and oil from adhering to it and further to protect against change of colour from ocurring due to ultraviolet radiation. Accordingly even though it is installed outside, its reflection effect is continued as it was and its product life span is fully extended.

As shown in above, this invention's traffic collar cone is made of flexible material and designed to be recover its previous shape as it was after lapse of impact so that it is possible to eliminate the injury to the collar cone even after being collided with by a vehicle and guarantee its use for, a maximum long time, and enhance the work efficiency; thereby high productivity and economic efficiency can be obtained.
