Description
본 발명은 도로시설용 반사판, 더욱 상세히는 운전자에게 운행정보를 제공하기 위한 도로의 표지병, 안내 표지판, 지시판 또는 각종 도로 시설물 등에 사용되는 반사판에 관한 것으로, 특히 재귀반사율을 극대화 시켜 운전자의 육안인지도를 대폭향상 시킴으로써 각종 사고를 미연에 방지할 수 있게된 도로시설용 반사판에 관한 것이다.The present invention relates to a reflector for a road facility, and more particularly to a reflector used for a road sign bottle, a guide sign, a sign board, or various road facilities for providing driving information to a driver, and in particular, maximizes the retroreflective rate of the driver's visual guidance. The present invention relates to a reflector for a road facility that can be prevented in advance by greatly improving the accident.
일반적으로 각종도로 에는 도로의 상황, 전방안내, 속도규정, 방향지시, 위험지역 등의 운행정보를 제공하기 위한 다양한 시설물들이 설치되어 있으며, 이러한 지시, 안내 사항은 전조등의 불빛을 양호하게 반사하도록 문자, 도형으로 구성한 반사수단을 시설물에 부착, 고정등의 방법으로 설치하여 운전자의 육안확인에 의해 도로정보를 제공받게 되어 있음은 주지와 같다.In general, various roads are equipped with various facilities to provide driving information such as road conditions, forward guidance, speed regulation, direction instructions, and danger zones, and these instructions and instructions are written to properly reflect the lights of the headlights. It is well known that the vehicle is provided with road information by visually confirming the driver by installing the reflecting means formed in the figure by attaching or fixing the facility.
상기한 종래 반사수단은 다양한 형태, 구성의 것들이 제시 사용되고The conventional reflecting means described above are used in various forms, configurations
있는바, 도 1에는 반사지(1A)의 대표적 구성이 도시되어 있다.As shown in FIG. 1, a representative configuration of the reflective paper 1A is shown.
이는, 셀로판지 등이 보호지(11)에 접착층(12)을 도포하여 반사층(13)을 구성시키고, 반사층(13)의 상면에는 미세유리구슬(micro glass bead:14 )을 유착층(15)에 의해 고정시킨후 투명수지층(16)을 표면에 형성시킨 구성의 것으로, 광원으로 부터 입사된 빛을 대체로 난반사 시키게 되므로 육안 인지도가 낮다는 문제점이 지적되고 있다.The cellophane or the like is coated with the adhesive layer 12 on the protective paper 11 to form the reflective layer 13, and the micro glass beads 14 are formed on the upper surface of the reflective layer 13 by the adhesion layer 15. Since the transparent resin layer 16 is formed on the surface after being fixed, since the light incident from the light source is generally diffusely reflected, a problem of low visual recognition is pointed out.
도 2에는 고휘도 반사지(1B)를 나타낸 것으로, 이는 차례로 적층 구성된 보호지(11)와 접착층(12) 및 반사층(13)의 표면에 유착층(15)에 의해 미세유리구슬(14)을 접착시키되 그 상부에는 공기층(17)이 형성되도록 투명수지층(16)을 형성시킨 구성이다.2 shows a high-brightness reflective paper 1B, which in turn bonds the fine glass beads 14 to the surfaces of the protective paper 11, the adhesive layer 12, and the reflective layer 13, which are formed by lamination, by the adhesion layer 15. The transparent resin layer 16 is formed to form an air layer 17 thereon.
이러한 고휘도 반사지(1B)는 일반적인 반사지(1A)에 비해 상대적인 인지도 상승효과는 있으나, 운전자가 확실하게 육안확인할 수 있는 정도의 재구 반사율을 나타내지는 못하며, 반사지(1A)와 고휘도 반사지(1B) 모두는 우천, 먼지, 태양광 등에 의해 쉽게 오염 및 파손된다는 문제점이 지적된다.The high brightness reflector 1B has a relatively increased recognition effect compared to the general reflector 1A, but it does not exhibit a reconstructive reflectance that the driver can visually check, and both the reflector 1A and the high brightness reflector 1B It is pointed out that it is easily polluted and damaged by rain, dust, sunlight, and the like.
상기한 내구성의 문제점을 해소시킬 수 있는 반사수단으로는 도 3에 나타낸 초 고휘도 반사판(1C)이 있다.As the reflecting means capable of solving the above-mentioned problems of durability, there is an ultra-high brightness reflecting plate 1C shown in FIG.
이는, 보호지(11)에 접착층(12)을 형성시켜 봉입필름(18)을 적층시키고 그 상면에 공기층(19)이 형성되도록 반사판(20)을 접착시킨후 보호필름(21)으로 표면처리한 것으로, 반사판(20)의 하면에는 삼각입방체의 미세돌기(22)들을 밀집배열 형성시킨 것이다.This is because the adhesive layer 12 is formed on the protective paper 11 to laminate the encapsulation film 18, and the reflective plate 20 is adhered to form an air layer 19 on the upper surface thereof, and then surface treated with the protective film 21. On the lower surface of the reflector plate 20, the fine protrusions 22 of the triangular cube are densely arranged.
그러나, 이런한 초고휘도 반사판(1C)은 어느 정도의 반사효율 향상 효과는 얻을 수 있지만, 충격에 약하여 유리보수에 많은 시간과 경비가 요구되고, 제작비용의 과대히 높아진다는 문제점이 지적된다.However, the ultra-high brightness reflecting plate 1C is able to obtain a reflection effect improvement effect to some extent, but it is pointed out that the problem is that it is weak to impact, requires a lot of time and expense for glass repair, and excessively high production cost.
도 4에는 가장 근대에 도로표지병등에 사용되는 반사판(1D)을 예시한 것으로, 2∼3mm 직경의 유리구슬(23) 하면에 반사층(13)을 형성시키고, 이를 분리방지되도록 일정간격으로 합성수지재의 베이스(24)에 삽입사출 시킨 구성의 것이다. 그러나, 이러한 반사판(1D)은 유리구슬(23)이 일정간격을 유지하며 설치되어 있으므로 재귀반사효율을 향상시키기 위한 원래의 목적을 달성하기 어렵고, 대단히 고가이며, 베이스(24)의 내구성 특히 내충격성이 불량하여 도로표지병 등의 내부에 은폐설치 시켜야 한다는 등의 여러가지 문제점들이 지적되고 있다.FIG. 4 illustrates a reflector plate 1D used for a road sign bottle at the most modern time. The reflective layer 13 is formed on the lower surface of the glass beads 23 having a diameter of 2 to 3 mm, and the base of the synthetic resin material is spaced at a predetermined interval to prevent separation. It is of the configuration inserted in (24). However, such a reflector plate 1D is difficult to achieve the original purpose of improving the retroreflective efficiency because the glass beads 23 are installed at constant intervals, and are extremely expensive, and the durability of the base 24, in particular, impact resistance. This problem is pointed out that various problems such as the need to cover up inside the road sign bottle.
한편, 상기한 종래 반사수단들은 공통적으로 전량 수입에 의존해야 하므로 엄청난 외화의 낭비가 발생되고, 사용시에는 필요 용도 이외에는 사용할수가 없으며, 동일한 용도의 경우에도 규격에 따라 별도로 구입해야 함은 물론, 유지보수가 어렵다는 문제점도 지적되고 있다.On the other hand, since the conventional reflecting means must rely on the total amount of import in common, a great waste of foreign currency is generated, and can not be used other than the necessary use when used, and even in the same use, separately purchased according to the standard, of course, maintenance The problem of being difficult is also pointed out.
본 발명은 상기한 문제점을 감안하여 재귀반사효율을 극대화시켜 운전자의 인지도 향상을 구현할 수 있고, 저가제작이 가능하면서도 내구성이 대폭향상되어 원가절감 및 유지보수의 용이함을 도모할 수 있으며, 필요 용도, 형태에 맞추어 다양하게 사용할 수 있는 도로 시설용 반사판을 제공함에 그 목적이 있다.The present invention can realize the driver's awareness by maximizing the retroreflective efficiency in consideration of the above-mentioned problems, and can be manufactured at low cost, while greatly improving the durability, thereby reducing cost and easy maintenance, necessary use, The purpose is to provide a reflector for road facilities that can be used in various ways according to the form.
상기 목적을 효과적으로 달성하기 위한 본 발명 반사판은, 전,후면에 각각 반구형의 입사부와 호형의 반사부를 밀집형성시킨 수지층과, 상기 반사부의 하면에 접착고정된 미세유리구슬과, 상기 미세유리구슬의 하면에 수은코팅 형성시킨 반사층으로 구성되며, 상기 반사층의 하면에는 필요에 따라 보호층을 구성시킬 수도 있도록 구성된다.Reflective plate of the present invention for achieving the above object effectively comprises a resin layer in which the hemispherical incidence portion and the arc-shaped reflection portion are densely formed on the front and rear surfaces, micro glass beads adhered and fixed to the lower surface of the reflection portion, and the micro glass beads. It is composed of a reflective layer formed on the lower surface of the mercury coating, the lower surface of the reflective layer is configured so that a protective layer may be configured as necessary.

이하에서 상기 본 발명의 바람직한 실시예를 첨부 도면에 의해 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 5는 본 발명에 의한 반사판(1)의 평면도로서, 넓은 판체로 구성되어 필요에 따라 절단 사용할 수 있도록 구성되는데, 이 수지층(25)은 내충격성과 내마모성이 우수하여 방판용으로 널리 사용되는 폴리카보네이트(poly carbonate) 수지를 사용함이 바람직하며, 아크릴 수지로 형성하여도 무방하다.5 is a plan view of the reflecting plate 1 according to the present invention, which is composed of a wide plate to be cut and used as needed, and the resin layer 25 is excellent in impact resistance and abrasion resistance, and is widely used for a plaque. It is preferable to use a polycarbonate resin, and may be formed of an acrylic resin.
상기 수지층(25)의 표면에는 반구형의 입사부(26)가 밀집형성 되는데, 밀집도를 높이기 위해 도 5에서와 같이 45°각도로 배열시킴이 바람직하다.The hemispherical incidence portion 26 is densely formed on the surface of the resin layer 25, and in order to increase the density, it is preferable to arrange at a 45 ° angle as shown in FIG. 5.
상기 수지층(25)에 형성시킨 입사부(26)의 수직하부에는 도 6 에서와 같이 호형의 반사부(27)가 입사부(26)와 동일한 직경으로 배열형성된다.In the vertical lower portion of the incidence portion 26 formed in the resin layer 25, an arc-shaped reflecting portion 27 is formed in the same diameter as the incidence portion 26 as shown in FIG.
상기 반사부(27)의 하면에는 미세유리구슬(14)이 접착고정되며, 상기 미세유리구슬(14)의 하면에는 수은코팅형성시킨 반사층(13)이 형성된다.The micro glass beads 14 are adhered to and fixed to the lower surface of the reflector 27, and a reflective layer 13 formed with mercury coating is formed on the lower surface of the micro glass beads 14.
이와같은 구성의 본 발명 반사판(1)은 도 7 에서와 같이, 차량의 전조 등으로부터 나오는 불빛이 입사부(26)를 통해 굴절 입사되어 호형의 반사부(27)를 통과하게 되는데, 반사부(27)를 통과한 빛은 미세유리구슬(14)로 굴절입사된후 반사층(13)에 의해 반사되어 입사부(26)를 통해 전조등 측으로 재귀 반사된다.In the reflective plate 1 of the present invention as described above, as shown in FIG. 7, the light from the headlight of the vehicle is refracted through the incident part 26 to pass through the arc-shaped reflector 27. The light passing through 27 is refracted by the fine glass beads 14 and then reflected by the reflective layer 13, and then retroreflected to the headlamp side through the incident part 26.
상기한 재귀반사는 반사판(1)의 어느 각도에서 빛이 입사되어도 동일한 효과를 나타내며 따라서, 운전자의 인지도는 대폭향상된다.The above retroreflective reflects the same effect even when light is incident from any angle of the reflecting plate 1, and thus the driver's recognition is greatly improved.
도 8 은 본 발명 반사판(1)의 작용을 설명하기 위한 비교 구성도로서, 여기서는 반사판(1)의 입사부(26)와 반사부(27)를 동일한 반구형, 전체적으로는 구형으로 형성시킨 상태를 나타내었다.FIG. 8 is a comparative configuration for explaining the operation of the reflecting plate 1 of the present invention. Here, the incidence portion 26 and the reflecting portion 27 of the reflecting plate 1 are formed in the same hemispherical shape, which is generally spherical. It was.
이경우에는 본 발명에서와 같이 입사각에 구애됨 없이 탁월한 재귀반사효과를 나타낼 수 있지만, 전체적인 두께가 두꺼워 지므로 소요자재 증가와 원가상승이 유발되며, 이에 반하여 본 발명 반사판(1)은 반사부(27)가 호형으로 형성되므로 제품의 슬림(slim)화가 가능하며 더욱큰 원가절감 효과를 얻을 수 있게 된다.In this case, as shown in the present invention, but can exhibit excellent retroreflective effect without regard to the angle of incidence, but the overall thickness becomes thick, causing an increase in material requirements and cost increase, on the contrary, the reflector 1 of the present invention is a reflector 27 Because it is formed in arc shape, it is possible to slim the product and obtain more cost reduction effect.
도 9 는 본 발명 반사판(1)의 하면에 접착된 미세유리구슬(14)의 작용을 설명하기 위한 비교 구성도로서, 여기서는 반사부(27)의 하면에 직접 반사층(13)을 코팅형성 시킨 상태를 나타내었다.9 is a comparative configuration for explaining the action of the micro glass beads 14 adhered to the lower surface of the reflector 1 of the present invention, in which the reflective layer 13 is directly coated on the lower surface of the reflector 27. Indicated.
이 경우에는, 차량의 전조등으로부터 입사되는 빛이 반사부(27)에서 반사층(13)에 의해 각도가 변화된후 반대방향의 반사부(27)에서 다시한번 반사되어 입사방향과 전혀 다른 방향으로 반사되므로 특정한 입사각도가 아닌 경우에는 재귀효과를 기대할 수 없으나, 이에 반하여 본 발명에서는 미세유리구슬(14)이 입사된 방향으로 빛을 반사시켜 주게 되므로 탁월한 재귀반사 효과를 얻을 수 있게 된다.In this case, since the light incident from the headlight of the vehicle is changed by the reflecting layer 13 in the reflecting portion 27 and reflected by the reflecting portion 27 in the opposite direction again, it is reflected in a direction completely different from the incident direction. When the angle of incidence is not a specific recursion effect can not be expected, on the contrary, in the present invention, since the fine glass beads 14 reflect light in the incident direction, an excellent retroreflection effect can be obtained.
도 10 은 본 발명 반사판(1)의 다른 실시예를 나타낸 것으로, 여기서는10 shows another embodiment of the reflector 1 of the present invention, where
반사층(13)의 하면에 보호층(28)을 형성시켜 반사층(13)의 긁힘 또는 박리로인한 기능 저하가 방지되도록 하였다.A protective layer 28 is formed on the lower surface of the reflective layer 13 to prevent a decrease in function due to scratching or peeling of the reflective layer 13.
상기 보호층(28)은 보호필름이나 수지코팅등의 다양한 방법에 의해 구성될 수 있다.The protective layer 28 may be configured by various methods such as a protective film or a resin coating.
이와같이 본 발명 반사판은, 그 구성과 제작이 극히 단순 용이하여 원과절감과 대량생산이 가능하고, 사용시에는 방향에 구애됨 없이 우수한 재귀반사 효과를 나타내어 운전자가 도로운행 정보를 쉽게 육안 확일할 수 있으므로 인지도 향상에 의한 사고 예방효과를 얻을 수 있으며, 사용목적, 용도 또는 필용에 따라 필요한 너비와 길이로 절취사용할 수 있음은 물론, 내충격성과 내마모성이 우수하여 유지보수가 용이한 등의 광범위한 효과가 있다.As described above, the reflector of the present invention is extremely simple in its construction and fabrication, and thus can be reduced in mass and mass production, and when used, it exhibits excellent retroreflective effect without regard to the direction, so that the driver can easily visualize the road information. Accident prevention effect can be obtained by improving awareness, and it can be cut and used to the required width and length according to the purpose of use, purpose or use, as well as easy to maintain due to its excellent impact resistance and wear resistance.
