Description

A road stud with standing side impacts closing the road}

The present invention relates to a road sign bottle which is arranged at regular intervals in a lane and can guide a vehicle by reflecting light from a vehicle at night. In particular, a urethane rubber elastic body is included and is flexible, and external impact such as a vehicle wheel is applied. The present invention relates to a new concept of road marking bottle that falls down into the ground road and is not damaged.

In general, road marker bottles with reflectors are installed on the center line or sloped roads where lane boundaries are unclear, and vehicles running in dark nights can check lane boundaries and drive safely. have. However, such a conventional road marker bottle has a reflector projecting on the road surface, and the impact of the wheels is directly transmitted to the vehicle, which may cause problems in safe operation. In many cases, it is easily broken by the weight of the car body.

In addition, during the snow removal operation of the snow plow in winter, it was often damaged by the snow blade. For this reason, in general, road signs are useless in mountainous areas where there is a lot of snow.

In order to solve the above problems, Patent Application No. 10-639364 (Invention: Road Sign Bottle Using Urethane Rubber Elastic Body), which has been invented and registered by the present applicant, is disclosed. The patent has an outer passage having one or more receiving holes and embedded in the road; The airtightly installed in the receiving hole, the central wall is formed with ventilation holes for ventilating the air in the storage hole to the outside by lifting, a fluid passage connected to the ventilation holes, a plurality of pairs installed before and after the central wall A lifting tube provided between the reflecting display panels and the reflecting plates, the guide surface having an inclined shape so as not to catch a snow blade; Urethane rubber disposed in the receiving hole so as to elastically support the lifting pipe is connected to the outer cylinder and the lifting pipe, the fluid passage communicating with the fluid passage of the lifting pipe and the water suction hole connected to the fluid passage is formed. Including an elastic body is a structural feature.

Unlike the conventional road sign bottle, the road sign bottle has an advantage that the lifting tube can be lowered into the road when it is impacted from the outside, such as a vehicle wheel, by the operation of the urethane rubber elastic body therein, so that there is little risk of damage. However, when the snowplow passes, the blade of the snowplow is applied from the side of the road cover bottle, so that it is caught by the wing of the outer cylinder, that is, the road surface support part, and all road cover bottles formed higher than the road support part are cut off and broken. Therefore, the road marker bottle is excellent in the effect of the downward impact from the outside, but the effect is insignificant for the side impact.

Therefore, the present invention is to solve the problem to provide a road marking bottle that does not fall by falling into the road surface when the impact from the outside, in particular when the side impact from the outside is applied to the road surface, such as the blade of the snowplow.

In another aspect, the present invention is to provide a method for effectively embedding the road marker bottle on the road as a second problem to be solved.

The present invention as a means for solving the above problems

A reflector 12 capable of reflecting light;

A central wall surface 14 having a space in which the glass grain reflector is inserted;

A vent hole 11 installed at one side of the central wall surface;

An elevating pipe body 10 having an inclined guide surface 13 having an inclined shape provided at both side surfaces of the central wall surface;

An outer cylinder 20 having an accommodating space 21 in which the elevating pipe body 10 is accommodated;

In order to elastically support the elevating pipe body 10 is provided a road sign bottle composed of a urethane rubber elastic body 30 disposed in the receiving space (21).

In addition, the present invention is characterized by attaching three rectangular road surface attachment means 22 having a shape bent toward the ground on the upper surface edge of the outer cylinder 20 and riveting it with the outer cylinder.

On the other hand, the present invention is characterized in that the road marker bottle is arranged at regular intervals along the lane to be embedded in the road so that the upper edge of the elevating pipe body 10 is located at the bottom of the road.

The road marker bottle of the present invention has an effect of minimizing the surface area subjected to external impact on the side of the road attachment means smaller than the conventional road marker bottle. Therefore, when the road marker bottle of the present invention is buried in a road lane in a snowy area, it is possible to install an effective road marker bottle that can withstand much more on the blade of the snowplow than the existing road marker bottle. In addition, when laying the edge of the elevating pipe slightly lower than the road, when the side impact, such as the blade of the snowplow, the force acts along the inclined guide surface and descends into the road, eliminating the fear of road sign bottle breakage. .

Hereinafter, the present invention will be described in more detail with reference to the drawings.

1 is a perspective view showing the overall configuration of a road sign bottle of the present invention. As shown in FIG. 1, the road marker bottle of the present invention includes a central wall 14 having a reflector and a space into which the reflector is inserted, and an amount of ventilation holes 11 and the central wall provided at one side of the central wall. An outer cylinder 20 having an elevating pipe body 10 having an inclined guide surface 13 having an inclined shape provided on the side, and a receiving space 21 in which the elevating pipe body 10 is accommodated, and the elevating pipe body 10 are burnt. It is composed of a urethane rubber elastic body 30 (not shown in Figure 1) disposed in the storage space 21 for sexual support.

The reflector 12 may serve to guide the vehicle by reflecting the vehicle light, and may be selected regardless of the material or shape as long as it can function to reflect the vehicle light. In the present invention, the spherical glass ball reflector is adopted in consideration of the convenience and aesthetic value of the manufacturing process, the manufacturing cost, the reflection effect, etc., but is not necessarily limited thereto.

The upper surface of the elevating pipe body 10 is formed to have a constant inclination angle in order to be able to descend into the road against side impacts such as blades of the snowplow. The upper surface of the elevating pipe body 10 has a center, which is a space into which the glass grain reflector is inserted, and an inclined guide surface on both sides of the central wall surface. The inclination angle of the inclined guide surface is preferably formed at about 20 ° to 25 ° so as to descend into the road with respect to the side impact of the blade of the snowplow, but is not necessarily limited thereto.

The outer cylinder 20 is graphite coated on the inner receiving space, the upper surface is attached to the road surface attachment means 22, the road surface attachment means 22 is preferably installed in three square Passage is combined using rivets, and the cross section is installed in a slightly bent shape along the road surface.

The elevating pipe body is installed in close contact with the outer cylinder, but is configured such that the upper surface edge of the elevating pipe body is installed at a somewhat lower portion than the upper surface of the outer cylinder, in particular, the portion that is riveted to the road surface attachment means 22.

2 is an exploded perspective view of the road marker bottle of the present invention. As shown in Figure 2, the side of the elevating pipe body is formed with a plurality of grooves and urethane square ring is pressed in the groove is installed in close contact with the storage space of the outer cylinder. The urethane square ring further strengthens the adhesion between the elevating pipe and the outer cylinder, thereby preventing foreign substances such as water or soil from penetrating the elevating pipe and the outer cylinder, as well as external impacts such as blades of a vehicle wheel or snowplow. It is responsible for absorbing it. To this end, the urethane square ring is used by graphite coating treatment. In addition, the urethane rubber elastic body 30 is formed to have a urethane hardness of about 70 to elastically react to external impacts, such as blades of a vehicle wheel or snowplow, and the lower portion is formed to have a urethane hardness of about 90 Resist shock.

In order to further secure the fastening of the elevating pipe body and the urethane rubber elastic body 30, it is integrally formed by the washer member 50 and the snap ring 60. In addition, the urethane rubber elastic body 30 has a water suction hole 31 and a pin fixing hole 32 is formed in the lower portion and the outlet 64 is formed in the center, the water suction hole 31 is The water is sucked and discharged through the air vent 11 of the elevating pipe through the outlet 33 in the center.

3 is a view showing a state in which the road marker bottle of the present invention is embedded in the road. As shown in FIG. 3, the elevating pipe body is integrally coupled with the urethane rubber elastic body and tightly fastened to the outer cylinder, and the bottom lower end of the urethane rubber elastic body is configured to close a hole using a stopper 80. This is done by digging holes and using epoxy resin when embedding road marker bottles in order to prevent epoxy resin from penetrating into road marker bottles.

In addition, the outer cylinder is attached to the road surface through the road surface attachment means 22 on the upper edge. The road surface attachment means has a shape slightly bent toward the ground and the upper surface edge of the elevating pipe is configured to be in close contact with the bottom slightly compared to the inner surface of the outer cylinder to be in close contact. This is to induce the impact on the inclined surface of the elevating pipe when the side impact such as the blade of the snowplow is applied from the outside to lower the road surface during side impact. This will be described in more detail below.

When a falling shock such as a vehicle wheel is applied, the impact is absorbed by the elasticity of the urethane rubber elastic body installed inside the lifting pipe, and the lifting pipe is lowered below the road surface. The shock absorption and the downward movement for the falling impact can also be achieved by the road marker bottle using a conventional urethane rubber elastic body such as the above-described Patent 10-639364.

However, road markers installed in snowy areas must be able to withstand the blades of snow plows. The blades of snow plows do not impact downward like the wheels of the vehicle, but rather close to the road from the side. Existing road marker bottle, even if the elasticity is good absorbs the external impact well even if descending movement contact the road surface that is in contact with the road surface attachment means in the present invention the impact of the blade of the snowplow car to damage it and the above All parts that do not have an inclined surface located above the road attachment means are damaged. Therefore, the existing road marker bottle has a wing shape in which the means attached to the road surface is integrally formed with the outer cylinder. When the blade of the snowplow is impacted through the bottom of the wing in close contact with the ground, the lifting tube corresponding to the upper part of the wing Is bound to break.

On the other hand, the road marking bottle of the present invention has a form in which the road surface attachment means is slightly bent toward the ground as described above, so that the road surface attachment means of the portion in close contact with the road surface may be damaged by the blade of the snowplow, but the bent portion The road surface attachment means of the riveted portion is located slightly lower than the ground of the snowplow, so the blade of the snowplow can be avoided. In addition, the edge of the upper surface of the elevating pipe is configured to be in close contact with the bottom slightly compared to the inner surface of the outer cylinder to be in close contact, so that the blade of the snowplow is directly directed to the inclined guide surface of the elevating pipe so that the inclined guide surface is subjected to side impact. Will descend. Therefore, it is possible to provide a road marker bottle that can easily withstand not only snowplows but also various impacts applied to the road surface.
