구명조끼{LIFE VEST}Life jacket{LIFE VEST}

본 발명은 구명조끼에 관한 것으로서, 보다 상세하게는 빛 반사가 매우 우수한 형광 물질이 구명 조끼의 외면에 구비되어 조난자가 쉽게 식별되도록 함으로써 구조 작업이 신속하고 효율적으로 이루어지도록 하는 동시에, 별도의 전원이 구비되지 않더라도 구명 조끼의 외면에서 발광이 이루어지도록 하여 형광 효과를 더욱 배가함으로써 야간에 조난자의 구조 확률을 높여줄 수 있는 구명조끼에 관한 것이다.The present invention relates to a life jacket, and more particularly, a fluorescent material having very excellent light reflection is provided on the outer surface of the life jacket so that the victim can be easily identified, so that rescue work can be performed quickly and efficiently, and a separate power supply is required. It relates to a life jacket capable of increasing the probability of rescue of a victim at night by further doubling the fluorescence effect by allowing light emission from the outer surface of the life jacket even if not provided.

해양에서 조난자는 사고 지점에 그대로 머물러 있지 못하고 파도에 의해 표류하게 된다. 파도에 의해 표류되는 조난자는 구조 작업이 신속히 이루어지는 경우, 사고 지점으로부터 그리 멀지 않은 지점에서 발견될 수 있지만, 구조 작업이 신속히 이루어지지 못하는 상황이거나 또는 사고 지점 주변의 파도가 매우 강한 경우 등의 상황에서는 사고 지점으로부터 동떨어진 먼 곳까지 표류되어 구조가 힘들어질 수 있으며, 이와 같은 상황에서 구조대는 조난자를 발견하기 위해 추가적인 수색작업을 수행하게 되어 구조 작업이 어렵게 될 수 있다. In the ocean, the victim cannot stay at the accident site and is drifted by the waves. A survivor drifting by waves can be found at a point not far from the accident site if rescue work is carried out quickly, but in situations where rescue work is not done quickly or when the waves around the accident site are very strong, etc. Rescue may be difficult due to drifting away from the accident point, and in such a situation, rescue teams may perform additional search work to find the victims, making it difficult to rescue.

이러한 조난자 식별의 어려움은 시야가 극도로 제한되는 야간인 경우에 더욱 가중되어 원활한 구조 작업을 방해하고 급박한 상황에 처한 조난자의 생명을 위태롭게 만드는 문제점이 있다. Difficulty in identifying the victims is further aggravated in the case of the night when the field of vision is extremely limited, thereby interfering with the smooth rescue operation and endangering the lives of the victims in urgent situations.

본 발명은 상기 문제점을 해결하기 위해 안출된 것으로서, 본 발명의 목적은 빛 반사가 매우 우수한 형광 물질이 구명 조끼의 외면에 구비되어 조난자가 쉽게 식별되도록 함으로써 구조 작업이 신속하고 효율적으로 이루어지도록 하는 동시에, 별도의 전원이 구비되지 않더라도 구명 조끼의 외면에서 발광이 이루어지도록 하여 형광 효과를 더욱 배가함으로써 야간에 조난자의 구조 확률을 높여줄 수 있는 구명 조끼를 제공하려는 것이다.The present invention has been conceived to solve the above problem, and an object of the present invention is that a fluorescent material having very excellent light reflection is provided on the outer surface of a life jacket so that the victim can be easily identified, so that rescue work can be performed quickly and efficiently. However, even if a separate power source is not provided, it is intended to provide a life jacket capable of increasing the probability of rescue of the victims at night by further doubling the fluorescence effect by allowing light emission from the outer surface of the life jacket.

상기 목적을 달성하기 위해, 본 발명에 따른 구명조끼는, In order to achieve the above object, the life jacket according to the present invention,

전면부의 상측 및 후면부의 상측 외면에 형광체가 구비되고, 구명조끼의 전면부의 상측에 압전소자가 내장되며, 구명조끼 착용자의 어깨 부위에 배치되는 구명조끼의 외면에 설치됨과 아울러 상기 압전소자와 연결되어 상기 압전소자로부터 전원을 공급받아 고휘도로 발광하는 발광체를 포함한다.Phosphors are provided on the upper outer surface of the upper and rear part of the front part, a piezoelectric element is embedded in the upper part of the front part of the life jacket, installed on the outer surface of the life jacket disposed on the shoulder of the life jacket wearer, and connected to the piezoelectric element.

바람직한 실시예로서, 상기 형광체는 야간 빛 반사율이 우수한 산화유로퓸, 산화디스프로슘, 산화스트론튬, 산화네오디뮴, 및 칼슘설페이트를 포함하여 이루어지되, 형광체 전체 중량에 대해 산화유로퓸은 20~30중량%, 산화디스프로슘은 10~30중량%, 산화스트론튬은 5~15중량%, 산화네오디뮴은 10~15중량%, 칼슘설페이트은 1~10중량%을 차지하는 것을 특징으로 한다.In a preferred embodiment, the phosphor is made of europium oxide, dysprosium oxide, strontium oxide, neodymium oxide, and calcium sulfate having excellent night light reflectance, but europium oxide is 20 to 30% by weight, dysprosium oxide based on the total weight of the phosphor. Silver 10 to 30% by weight, strontium oxide 5 to 15% by weight, neodymium oxide 10 to 15% by weight, calcium sulfate is characterized in that it occupies 1 to 10% by weight.

본 발명에 의하면, 구명 조끼의 외면에 구비된 형광체의 빛 반사율이 매우 우수하므로 야간 수색 작업시 조난자를 원거리에서도 쉽게 식별할 수 있으며, 구명조끼에 별도로 전원을 내장하지 않더라도 조난자의 간단한 조작으로 구명조끼에서 발광이 일어나므로 야간 수색시 더욱 더 조난자를 발견하기 용이하다.According to the present invention, since the light reflectance of the phosphor provided on the outer surface of the life jacket is very excellent, it is possible to easily identify the victim from a distance during the night search operation. Even if the life jacket does not have a separate power supply, the life jacket can be easily operated by the victim. It is easier to find the victims when searching at night because the light is emitted from.

도 1은 본 발명에 따른 구명조끼의 개략적인 외관을 나타내는 도면이다.1 is a view showing a schematic appearance of a life jacket according to the present invention.

본 발명의 구명조끼는 야간에 조난자의 구조 확률을 높일 수 있도록 빛 반사가 매우 우수한 형광 물질이 구명 조끼의 외면에 구비되는 것을 특징으로 한다.The life jacket of the present invention is characterized in that a fluorescent material having very excellent light reflection is provided on the outer surface of the life jacket so as to increase the probability of rescue of the victim at night.

이하에서, 첨부도면을 참조하면서 본 발명의 구명조끼를 더욱 상세히 설명한다.Hereinafter, the life jacket of the present invention will be described in more detail with reference to the accompanying drawings.

우선, 도 1에 도시된 본 발명에 따른 구명조끼는 구명조끼의 전면부(100)의 상측 및 후면부의 상측 외면에 형광체(110)가 구비되고, 구명조끼의 전면부(100)의 상측에 압전소자(120)가 내장되며, 구명조끼 착용자의 어깨 부위에 배치되는 구명조끼의 외면에 설치됨과 아울러 상기 압전소자(120)와 연결되어 상기 압전소자(120)로부터 전원을 공급받아 고휘도로 발광하는 발광체(130)를 포함한다.First, the life jacket according to the present invention shown in Figure 1 is provided with a phosphor 110 on the upper outer surface of the upper and rear portion of the front portion 100 of the life jacket, piezoelectric on the upper side of the front portion 100 of the life jacket A light emitter that emits light with high brightness by receiving power from the piezoelectric element 120 by being connected to the piezoelectric element 120 while being installed on the outer surface of the life jacket, which has a built-in element 120 and is disposed on the shoulder of the life jacket wearer. Including 130.

본 발명의 형광체(110)는 야간에 빛을 발하는 것으로서, 조난자가 물에 빠졌을 때에는 대부분 비스듬하게 누운 자세가 취해지기 때문에 상기 형광체(110)는 구명조끼의 전면부(100)의 상측과 후면부의 상측 외면에 구비되는 것이 바람직하다.The phosphor 110 of the present invention emits light at night, and when the victim is drowned in water, the phosphor 110 is mostly taken in an oblique position. Therefore, the phosphor 110 is the upper side and the upper side of the rear part of the front part 100 of the life jacket. It is preferable to be provided on the outer surface.

상기 형광체(110)는 질감이 있는 천으로 이루어질 수도 있고 부드러운 합성수지 재질로 이루어질 수도 있다.The phosphor 110 may be made of a textured cloth or a soft synthetic resin material.

또한, 본 발명에서는 구명조끼의 전면부(100)의 상측에 공지의 압전소자(120)가 내장된다. 상기 압전소자(120)는 구명조끼가 침수되었을 때 압전소자(120) 부위로 물이 침투하지 않도록 구명조끼의 전면부(100) 내부에 수밀한 구조로 설치되는 것이 바람직하다.In addition, in the present invention, a known piezoelectric element 120 is incorporated above the front part 100 of the life jacket. The piezoelectric element 120 is preferably installed in a watertight structure inside the front part 100 of the life jacket so that water does not penetrate into the portion of the piezoelectric element 120 when the life jacket is submerged.

따라서, 본 발명의 구명조끼는 별도의 전원 발생 장치가 구비되지 않고 단지 조난자가 상기 압전소자(120)를 가압하기만 하면 전원이 발생되게 되는 것이다.Accordingly, the life jacket of the present invention does not have a separate power generating device, and power is generated only when the victim presses the piezoelectric element 120.

본 발명의 발광체(130)는 상기 압전소자(120)와 전기적으로 연결되어 압전소자(120)에서 발생되는 전기를 공급받아 고휘도로 발광하는 공지의 발광 다이오드 또는 LED이다.The light-emitting body 130 of the present invention is a known light-emitting diode or LED that is electrically connected to the piezoelectric element 120 to receive electricity generated from the piezoelectric element 120 and emit light with high brightness.

따라서, 조난자가 야간에 상기 압전소자(120)가 내장된 구명조끼 부위를 가압하면 상기 발광 다이오드인 발광체(130)가 발광하게 되므로 조난 신호를 가시적으로 알릴 수 있다. Therefore, when the person in distress presses the part of the life jacket in which the piezoelectric element 120 is embedded at night, the light-emitting body 130, which is the light-emitting diode, emits light, so that a distress signal can be visually informed.

본 발명은 상기 형광체(110)를 보다 밝게 발광시키기 위해 야간 빛 반사율이 우수한 산화유로퓸, 산화디스프로슘, 산화스트론튬, 산화네오디뮴, 및 칼슘설페이트를 포함하여 이루어진다.The present invention includes europium oxide, dysprosium oxide, strontium oxide, neodymium oxide, and calcium sulfate having excellent night light reflectance in order to emit light more brightly from the phosphor 110.

보다 상세하게 상기 형광체(110)는 일정 사이즈의 천 또는 합성수지재에 상기 성분들이 도포되어 구명조끼에 부착되는 것이다. In more detail, the phosphor 110 is attached to a life jacket by applying the ingredients to a cloth or synthetic resin material of a certain size.

상기 산화유로퓸, 산화디스프로슘, 산화스트론튬, 산화네오디뮴, 및 칼슘설페이트는 모두 형광성 물질이다.The europium oxide, dysprosium oxide, strontium oxide, neodymium oxide, and calcium sulfate are all fluorescent substances.

일 실시예로서, 상기 형광체(110)는 형광체 전체 중량에 대해 산화유로퓸이 30중량%, 산화디스프로슘이 30중량%, 산화스트론튬이 15중량%, 산화네오디뮴이 15중량%, 칼슘설페이트이 10중량%을 차지할 수 있는데, 이와 같은 성분 배합에 의하면 형광 효과 또는 발광 효과가 더욱 높아진다.In one embodiment, the phosphor 110 contains 30% by weight of europium oxide, 30% by weight of dysprosium oxide, 15% by weight of strontium oxide, 15% by weight of neodymium oxide, and 10% by weight of calcium sulfate based on the total weight of the phosphor. It can occupy, but the fluorescence effect or the luminous effect is further increased according to such a composition.

결과적으로, 본 발명의 구명조끼는 야간에 조난자가 상기 압전소자(120)를 가압하여 발광체(130)를 발광시키면 그 발광에 의해 발광체(130) 주변에 부착된 형광체(110)에서 빛 반사가 더욱 활발하게 발생하게 되어 형광 효과 또는 발광 효과가 배가 되게 되는 것이다.As a result, in the life jacket of the present invention, when the injured person presses the piezoelectric element 120 to emit light at night, the light is reflected from the phosphor 110 attached around the luminous element 130 by the light emission. As it is actively generated, the fluorescence effect or the luminous effect is doubled.

본 발명의 바람직한 실시형태를 설명하였으나, 본 발명은 그 기술적 사상의 범위를 벗어나지않는 한도 내에서 여러 가지 변형이 가능함은 당해 분야의 통상의 지식을 가진 자에게 있어서 자명하다 할 것이다. 따라서, 상기 내용은 하기 특허청구범위에 의해 정해지는 본 발명의 범위를 한정하는 것이 아니다.Although preferred embodiments of the present invention have been described, it will be apparent to those of ordinary skill in the art that the present invention can be variously modified without departing from the scope of the technical idea.
