Description

[0001] The present invention relates to a sign having a multipoint dual spring absorbing structure,

The present invention relates to a signboard that can be installed as a guide sign and an advertisement sign in a street light, a KEPCO state, a telecommunications carrier, etc. In particular, it absorbs shocks with a vehicle to reduce damages to a driver and a vehicle, protects public facilities, Which is capable of significantly reducing the risk of collision due to excellent discrimination power by LED illumination of the cover guide by the power supply.

Generally, the public facilities include a street light for the safe passage of the vehicle at night, a tower for installing milestones, KEPCO for supplying electric power, and a communication stock for installing communication facilities. These landmarks are installed on highways, main roads, public roads, parks, and so on. Especially, in the case of a pillar installed on a roadside, it implies a risk of collision with a vehicle. In practice, when the vehicle collides with the landing gear, the damage to the vehicle and human life occurs largely, and the holding facility is also damaged. These accidents are mainly caused by bad weather, such as fogging on the roads, and at nighttime.

Thus, even if it is difficult to avoid collision with the landlord, many techniques have been proposed to reduce the impact and minimize the damage to facilities or human life.

As a background of the present invention, Korean Patent Laid-Open Publication No. 2003-0086152 proposes a vehicle collision mitigation device for a support. This is a fluid having a fluid filling port capable of filling the fluid therein and a fluid outlet for discharging the fluid inside and is formed of an elastic body absorbing the impact energy of the vehicle and is wound around the lower outer circumferential surface of the strut, A storage container; A viscous fluid that absorbs the impact energy of the vehicle and is filled in the fluid storage container; A container protective cover for covering the outer surface of the fluid storage container to protect the fluid storage container; And a fastener for tightening the outer surface of the container protective cover in a circumferential direction.

The above-mentioned background technology has an advantage of easy installation and replacement of only some damaged portions even after a collision, thereby reducing the maintenance cost. However, the background art has a problem that there is no means for clearly identifying the guide sign as well as the landing at night.

As another technology to be a background of the present invention, Korean Patent Registration No. 10-0641810 has proposed a 'spring-loaded metal spring holder capable of shock absorption and restoration'. A metal strut which is installed to absorb shock and restore after impact, comprising: a metal strut separated into an upper strut and a lower strut; Two plates respectively installed at the lower end of the upper strut and the upper end of the lower strut; A spring installed between the two plates; A steel wire connecting the two plates and installed on the outside of the spring; And a cushioning material provided around the two plates and the spring, wherein the cushioning material, the steel wire and the spring absorb the external impact in order.

The above-mentioned background technology has an advantage of easy installation and replacement of only some damaged portions even after a collision, thereby reducing the maintenance cost. However, in the background art, since the column is cut in the middle, and the upper side support is elastically supported on the lower side support via the spring, a risk of wobbling when a strong wind or a strong wind is generated in the case of the support provided with milestones, There is no means to clearly identify the landings or signs and the risk of nighttime collision is implied.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

A sign 100 having a multi-point dual spring buffer structure according to the present invention is installed in a road sign post 10 to perform the function of a shock sign, a warning sign, and an impulse sign. In addition, the sign 100 of the present invention may be applied to a street lamp, a telecommunication line, and the like.

1 shows a state in which a sign 100 having a multipoint dual spring buffer structure is installed on a column main body 12 of a road sign post 10, Fig. 2 is an enlarged view of part A of Fig. 1, 2 is a cross-sectional view taken along line BB of Fig. 3, Fig. 4A is a case without an LED panel, Fig. 4B is a case where an LED panel is installed, Figs. 5A and 5B are cross- Fig. 5B is a cross-sectional view of the state in which the impact-absorbing yielding member is further provided in Fig. 5A.

As shown in FIGS. 1 to 4B, a sign 100 having a multipoint dual spring buffer structure is installed on the lower side of the column body 12. A sign 100 having a multi-point dual spring buffer structure surrounds the outer circumferential surface of the column body 12, and a plurality of fastening bands 14 are fixedly installed in a section of a predetermined height. The fastening band 14 may be in the form of a circular band, fixed in the form of a combination of bolts and nuts, or in the form of fastening bands fixed by tightening the nuts.

At this time, the fastening band 14 may be closely attached to the attachment rubber 15 and fixed to the support body 12 so that the fastening band 14 is in close contact with the support body 12. The attachment rubber 15 is made of a rubber material and may be a single type or a separate type. The attachment rubber 15 has an annular groove 15a for fixing a band having a width corresponding to the fastening band 14 and having a predetermined depth on the outer circumferential surface (see FIG. 5A).

In the fastening band 14, a high-tension shock buffer unit 16 is installed to reduce the damage of the driver and the vehicle when the vehicle collides with the sign 100 having the multi-point dual spring buffer structure, and protect the support facility. In the present embodiment, the high-tension shock absorber unit 16 is provided with three stages in the height direction. At each end, a total of five high-tension shock absorbers 16 are arranged circumferentially. Therefore, the high-tension shock absorber 16 has a structure in which the high-tension shock absorbers 16 are arranged at a plurality of points over a predetermined interval around the strut body 12. Since the high-tension shock absorber unit 16 has a multi-point structure, the signboard 100 of the present invention effectively absorbs the impact energy by dispersing the external shock.

At this time, as shown in FIG. 4A, the high-tension shock absorber 16 is moved in a concentrated manner toward the roadway while increasing a certain angle? With respect to the normal line X connecting the center O of the landholder body 12 with the lane, And is arranged asymmetrically with respect to the vertical line Y perpendicular to the normal line X. This is because, when the high-tension shock absorber 16 is installed intensively toward the driveway, the shock absorption can be maximized corresponding to the direction of collision of the vehicle that has departed from the running direction.

The high-tension shock absorber unit 16 is bonded with a shock-absorbing protection plate 18 capable of protecting the supporting structure. The front surface of the buffering protection plate 18 may be printed with letters or symbols indicating a risk of collision and advertisements, or may be additionally provided with the LED panel 24 of FIG. 4B to be described later. It is preferable that the buffering protection plate 18 is formed in a curved shape that surrounds the outer periphery of the column body 12 for a certain period.

5A, the high-tension shock absorber 16 includes a spring support bolt 161 which is fixed to the fastening band 14 and is disposed in the radial direction of the strut body 12, a spring support bolt 161 which is fixed to the fastening band 14, An internal compression spring 163 having one end joined to the spring support bolt 161 and the other end fixedly connected to the spring support cap 162, An external compression spring 164 inserted in the outer diameter portion of the internal compression spring 163 and disposed between the spring support cap 162 and the spring support bolt 161 and an external compression spring 164 screwed to the spring support bolt 161 And a loosening prevention nut 165 for preventing loosening of the spring support bolt 161 screwed to the fastening band 14.

At this time, the external compression spring 164 may be installed between the spring support cap 162 and the spring support bolt 161 in a compressed or uncompressed state. Also, the loosening prevention nut 165 is not an essential component in the high-tension shock absorber unit 16, and the spring support bolt 161 may be provided on the fastening band 14 using a welding method or the like.

Therefore, when an impact is applied to the buffering protection plate 18, the high-tension shock buffering unit 16 absorbs the impact energy while the internal compression spring 163 and the external compression spring 164 are simultaneously compressed by the elastic deformation. The inner compression spring 163 and the outer compression spring 164 are compressed and deformed while the spring support cap 162 moves toward the spring support bolt 161. When the impact force is removed, The buffer protection plate 18 is restored to its original position by the elastic restoring force of the elastic restoring force of the elastic restoring force.

The high-tension shock absorber 16 may be provided with one or more shock-absorbing yielding members 30 for further increasing the absorption of external impact energy as shown in FIG. 5B. The impact-absorbing yielding member 30 is made of a resistance abdomen and has one end connected to the spring support bolt 161 and the other end connected to the spring support cap 162. At this time, the impact-absorbing yielding member 30 may be, for example, in the form of a wire having a circular cross-section. Therefore, the impact-absorbing yielding member 30 absorbs the impact energy by the plastic deformation when the shock-absorbing protection plate 18 is impacted and the high-tension shock absorbing unit 16 performs shock absorption.

Meanwhile, the sign 100 having the multipoint dual spring buffer structure of the present invention can be configured to enable the collision risk indication and advertisement through the illumination device.

4B, the lighting device includes a urethane pad 20 attached to the front surface of the buffering protection plate 18, an LED panel support plate 22 attached to the front surface of the urethane pad 20, an LED panel support plate 22, The LED panel 24 may be installed on the front surface of the LED panel 24. One surface of the urethane pad 20 is attached to the buffering protection plate 18 through an adhesive. The urethane pad 20 absorbs a part of the entire external impact received by the high-tension shock buffer unit 16 to protect the LED panel 24. The LED panel 24 includes an LED element and a driving circuit. The LED element is illuminated by a driving circuit to perform various character illumination or symbol illumination as shown in the figure.

2 and 3, a solar heat collecting plate 40 may be further installed on the column main body 12 to supply driving power to the LED panel 24 at this time. The power generated by the solar heat collecting plate 40 operates the driving circuit of the LED panel 24 to illuminate the nighttime, thereby facilitating the marking wall. Preferably, the power generated by the solar heat collecting plate 40 is stored in a rechargeable battery (not shown), and the LED panel 24 can be driven at night by the day / night sensor.

1, the sign 100 having the multi-point dual spring cushioning structure thus constructed is installed on the lower side of the column body 12 of the road sign post 10 installed on the foundation 5, for example, 16 to absorb the impact energy to function as a buffer. At this time, the buffering protection plate 18 protects the support main body 12. Therefore, in the event of a vehicle collision, it is possible to reduce the damage of the driver and the vehicle, and protect the facilities of the landlord itself. In addition, it can be utilized as a publicity advertisement of a police agency, a municipality or the like, an insurance company, or a communication company. In addition, not only at night, but also in bad weather such as fog or rainfall, the LED panel 24 lights up and the sign becomes clear and the visibility of the driver is improved, so that the risk of collision of the vehicle can be drastically reduced.
