Description

추락 방지 및 투신 자살 방어 회전체 시스템Fall prevention and throwing suicide defense rotator system
본 발명은 추락 방지 및 투신 자살 방어 회전체 시스템에 관한 것으로써, 보다 상세하게는 지지부에 회전가능하게 설치되는 회전부를 이용하여, 회전부가 투신시도자에 의해 파지되는 경우 회전부가 회전하여 투신시도자의 투신 및 추락이 효과적으로 저지될 수 있는 추락 방지 및 투신 자살 방어 회전체 시스템에 관한 것이다.The present invention relates to a fall prevention and projection suicide defense rotator system, and more particularly, by using a rotating part rotatably installed on the support, the rotating part is rotated when the rotating part is gripped by the projection attempting A fall prevention and throwing suicide defense rotating body system in which throwing and falling can be effectively prevented.
대한민국의 자살 사망률은 2011년 기준 인구 10만 명당 31.7명으로 지난 2003년 이후 현재까지 OECD 국가들 중 1위를 기록하고 있으며, 정부에서 2004년과 2009년에 각각 자살예방 종합대책을 두 차례나 내놓았음에도 불구하고 자살률은 지속적으로 증가하고 있다.South Korea's suicide mortality rate was 31.7 per 100,000 population in 2011, ranking 1st among OECD countries since 2003, and the government issued two measures to prevent suicide in 2004 and 2009, respectively. Despite this, suicide rates continue to rise.
한편, 근래에는 교량, 고층건물 등에서 투신하는 투신자살의 비율이 특히 급증하고 있다. 이러한 투신자살을 방지하기 위한 시설로는 교량, 고층건물 등의 가장자리에 설치되는 펜스가 있다.On the other hand, in recent years, the rate of suicide committed by bridges, high-rise buildings, etc. has been increasing rapidly. Facilities for preventing such suicide include fences installed at the edges of bridges and high-rise buildings.
하천이나 해상에 시공된 교량의 난간으로써 설치되는 펜스의 경우, 교량에 인가되는 풍하중 및 주변 경관과의 조화나 디자인 및 관망성 등을 고려하여 1m 내외의 비교적 낮은 높이로 설치된다. 상술한 바와 같이, 이러한 종래의 펜스는 설치되는 높이가 낮기 때문에, 투신시도자가 펜스를 타고 올라가 고의적으로 투신하는 것을 방지하기에는 효과적이지 못하다.In the case of fences installed as a railing of a bridge constructed in a river or at sea, the fence is installed at a relatively low height of about 1m in consideration of the wind load applied to the bridge and the harmony with the surrounding landscape, the design, and the network. As described above, since the height of the conventional fence is low, it is not effective to prevent the projection attempter from climbing up the fence and deliberately transmitting.
한편, 대형 건물의 옥상에 설치되는 펜스의 경우, 추락을 방지하기 위해서는 2 내지 3m 가량의 높이로 설치되어야 한다. 그러나, 대부분의 경우 비용 및 미관상의 이유로 1 내지 1.2m 남짓 되는 높이로 펜스가 설치되고 있어, 건물에 설치되는 펜스의 경우에도 교량의 경우와 마찬가지로 고의적인 투신 행위를 효과적으로 방지할 수는 없다.On the other hand, fences installed on the roof of a large building, in order to prevent the fall should be installed with a height of about 2 to 3m. However, in most cases, fences are installed at a height of about 1 to 1.2 m for cost and aesthetic reasons, and thus, fences installed in buildings cannot effectively prevent deliberate transmission acts as in the case of bridges.

도 1 내지 도 11에 도시된 바와 같이, 본 발명의 제1실시예에 따른 추락 방지 및 투신 자살 방어 회전체 시스템(100)은 지지부(110)와 회전부(120)와 감시카메라(130)와 스피커(140)와 관제센터(150)를 포함한다.1 to 11, the fall prevention and transmission suicide defense rotating system 100 according to the first embodiment of the present invention is the support 110, the rotating unit 120, the surveillance camera 130 and the speaker 140 and the control center 150.
지지부(110)는 일단부가 구조물에 설치되는 것으로써, 타단부는 후술하는 회전부(120)가 회전가능하게 설치된다.One end of the support 110 is installed in the structure, and the other end of the support 120 is rotatably installed.
여기서 구조물이란, 아파트, 고층건물, 일반주택의 옥상의 가장자리의 시설물 또는 교량, 고속화도로, 보도육교, 선박의 양 가장자리에 설치된 기존의 난간 또는 공연장, 관광지, 운동장에 설치된 난간, 기타 추락의 위험이 있는 장소에 설치된 물체 등일 수 있다. Here, the structure means the facilities or bridges on the edge of the roof of apartments, high-rise buildings, general houses, highways, sidewalks, existing railings installed at both edges of ships, railings installed on the tourist sites, sports grounds, and other dangers of falling. It may be an object installed in the place.
즉, 지지부(110)는 기존의 난간에 설치될 수 있으며, 이에 의해서, 투신 방지 시스템을 설치하는데 있어, 기존의 난간을 전체적으로 제거하는 불편함이 감소 되며, 투신 방지 시스템의 시공시, 기존의 난간을 그대로 활용할 수 있어, 시공시간 단축 및 시공단가 절약되는 이점이 있고, 유지 및 보수가 용이해지는 이점이 있다.That is, the support 110 may be installed in the existing railing, whereby, in installing the transmission prevention system, the inconvenience of removing the existing railing as a whole is reduced, during the construction of the transmission prevention system, the existing railing It can be utilized as it is, there is an advantage of reducing the construction time and construction stage, there is an advantage that easy maintenance and repair.
이러한 지지부(110)는 결합부(111)와 본체부(112)를 포함한다.The support part 110 includes a coupling part 111 and a main body part 112.
결합부(111)는 구조물에 결합되는 것으로써, 후술하는 본체부(112)가 상면에 설치된다. 이러한 결합부(111)는 체결부재에 의해 구조물에 결합될 수 있다. Coupling portion 111 is coupled to the structure, the main body 112 to be described later is installed on the upper surface. This coupling portion 111 may be coupled to the structure by a fastening member.
본체부(112)는 후술하는 회전부(120)가 일단부에 설치되는 것으로써, 타단부는 상술한 결합부(111)의 상면에 설치된다. 이러한 본체부(112)는 결합부(111)보다 좁은 폭으로 형성된다. 즉, 본체부(112)는 결합부(111)가 구조물에 설치되는 방향에 수직한 방향으로 결합부(111)의 상면에 설치되는데, 이때, 본체부(112)의 폭이 결합부(111)의 폭보다 좁도록 형성된다. The main body 112 is provided with one end of the rotating portion 120 to be described later, the other end is provided on the upper surface of the coupling portion 111 described above. The body portion 112 is formed in a narrower width than the coupling portion 111. That is, the main body 112 is installed on the upper surface of the coupling portion 111 in a direction perpendicular to the direction in which the coupling portion 111 is installed in the structure, wherein the width of the body portion 112 is the coupling portion 111 It is formed to be narrower than the width of.
이러한 본체부(112)의 결합구조에 의하면, 본체부(112)의 제작시에 재료가 적게 투입되므로, 본체부(112)의 제조 단가가 절감되는 효과가 있다.According to the coupling structure of the main body portion 112, since less material is input during the production of the main body portion 112, the manufacturing cost of the main body portion 112 is reduced.
한편, 본체부(112)는 지면에 대해 기설정된 각도(x)를 가지도록 마련될 수 있다. 기설정된 각도(x)는 40도 내지 75도 사이로 마련되는 것이 바람직한데, 지면을 기준으로 예각 또는 둔각을 모두 포함할 수 있다. 즉, 기설정된 각도(x)는 지면을 기준으로 예각 또는 둔각을 모두 포함할 수 있다. 즉, 기설정된 각도(x)가 예각인 경우 본체부(111)는 투신시도자를 향하는 방향으로 기울어지며, 기설정된 각도(x)가 둔각인 경우 본체부(111)는 투신시도자가 위치한 방향에 대향하는 방향으로 기울어진다.(도 3 및 도 6 참조)Meanwhile, the main body 112 may be provided to have a predetermined angle x with respect to the ground. The predetermined angle x is preferably provided between 40 degrees and 75 degrees, and may include both an acute angle and an obtuse angle with respect to the ground. That is, the predetermined angle x may include both an acute angle and an obtuse angle with respect to the ground. That is, when the preset angle x is an acute angle, the main body 111 is inclined in the direction toward the transmission viewer, and when the preset angle x is an obtuse angle, the main body 111 faces the direction in which the projection attempt is located. Inclined in the direction (see FIGS. 3 and 6).
또한, 이러한 본체부(112)는 주변환경을 고려하여 주변환경에 어울리는 다양한 형태로 제작될 수 있다.(도 7 참조)In addition, the main body 112 may be manufactured in various forms suitable for the surrounding environment in consideration of the surrounding environment (see FIG. 7).
또한, 이러한 본체부(112)에는 돌기(112d)가 형성될 수 있다. 이러한 돌기(112d)에 의해서, 투신시도자가 지지부(110)를 파지하여 오르려하는 것이 효과적으로 방지될 수 있다.In addition, a protrusion 112d may be formed on the main body 112. By this projection 112d, the attempted projection holder grasps the support 110 and can be effectively prevented.
한편, 도 4 및 도 5에 도시된 바와 같이, 본체부(112)에는 본체부(112)의 상단에 기설정된 외력이 인가되는 경우 본체부(112)의 상단이 지면을 향하는 방향으로 기울어졌다가 외력이 제거되면 다시 복원될 수 있게 하는 탄성수단(미도시)이 설치될 수 있다. 이러한 탄성수단(미도시)에 따르면, 투신시도자가 본체부(111)의 상단에 설치된 파이프(121)를 파지하는 경우, 파이프(121)가 지면을 향하는 방향으로 기울어져, 투신시도자의 무게중심이 교란될 수 있다. 따라서, 이러한 탄성수단(미도시)에 따르면, 투신시도자의 투신시도가 더욱 효과적으로 저지될 수 있다.4 and 5, when a predetermined external force is applied to the main body 112 at the upper end of the main body 112, the upper end of the main body 112 is inclined toward the ground. When the external force is removed, elastic means (not shown) may be installed to restore the power again. According to such elastic means (not shown), when the projection attempter grips the pipe 121 installed on the upper end of the main body 111, the pipe 121 is inclined toward the ground, so that the center of gravity of the transmission attempt It can be disturbed. Therefore, according to such elastic means (not shown), the transmission attempt of the transmission attempt can be more effectively prevented.
회전부(120)는 상술한 본체부(112)의 단부에 회전가능하게 설치되는 것으로써, 투신시도자에 의해 파지되는 경우 회전하여 투신시도자의 투신을 저지한다. The rotating part 120 is rotatably installed at the end of the main body part 112 as described above, and rotates when the gripper is gripped by the transmission attempt leader to prevent the transmission attempt.
이러한 회전부(120)는 복수개로 마련되어 본체부(112)에 경사를 이루도록 순차적으로 설치될 수 있다. 이때, 회전부(120) 사이의 간격은 투신시도자가 빠져나갈 수 없도록, 일반적인 성인의 머리의 좁은 측의 폭(13cm 내지 15cm)보다 더 작은 간격으로 마련되는 것이 바람직하다. 한편, 일반적인 성인의 신장이 170cm 라고 할 때, 회전부(120)는 상술한 간격을 고려하면, 3개로 마련되어 순차적으로 배치되는 것이 바람직하다. The rotation part 120 may be provided in plural numbers and may be sequentially installed to form an inclination to the main body part 112. At this time, the interval between the rotating unit 120 is preferably provided with a smaller interval than the width (13cm to 15cm) of the narrow side of the head of a general adult so that the projection attempt can not escape. On the other hand, when the height of the general adult is 170cm, in consideration of the above-described interval, it is preferable that the rotation unit 120 is provided in three and arranged sequentially.
상술한 회전부(120)는 파이프(121)와 축(122)과 베어링(123)과 압력센서(124)를 포함한다.The rotating unit 120 includes a pipe 121, a shaft 122, a bearing 123, and a pressure sensor 124.
파이프(121)는 내부공간을 형성하는 것으로써, 내부공간에는 후술하는 축(122)과 베어링(123)이 설치된다. 이러한 파이프(121)는 투신시도자가 파지하는 경우 내부의 베어링(123)에 접촉하며 회전함으로써, 투신시도자가 파이프(121)를 파지하며 오르는 것을 용이하게 방지한다. The pipe 121 forms an inner space, and the shaft 122 and the bearing 123 described later are installed in the inner space. The pipe 121 is rotated in contact with the bearing 123 therein when the projection attempter gripping, thereby easily prevent the projection attempts to climb and hold the pipe 121.
이러한 파이프(121)는 투신시도자가 쉽게 파지할 수 없도록 일반적인 사람의 손뼘 보다 더 큰 직경으로 마련되는 것이 바람직하다.The pipe 121 is preferably provided with a larger diameter than the hand of a general person so that the transmission attempt can not be easily gripped.
또한, 이러한 파이프(121)는 중량은 감소 되면서 강도는 커지도록 알루미늄(Aluminum) 재질로 마련되는 것이 바람직하다.In addition, the pipe 121 is preferably made of aluminum (Aluminum) material to increase the strength while reducing the weight.
한편, 이러한 파이프(121)에는 압력센서(124)가 설치될 수 있고, 파이프(121) 부근에는 후술하는 감시카메라(130) 및 스피커(140) 등의 시설이 설치될 수 있다. 이러한 압력센서(124), 감시카메라(130), 스피커(140) 등의 시설에 의해서, 투신시도자가 파이프(121)를 파지하는 경우, 관제센터(150)에서 이를 즉각적으로 인지하여, 스피커(140)로 경고음을 발생시킴과 동시에 관리인력을 즉시 투입시킬 수 있다. 이에 의해서, 투신시도자의 투신이 더욱 효과적으로 저지될 수 있다.Meanwhile, a pressure sensor 124 may be installed in the pipe 121, and facilities such as a surveillance camera 130 and a speaker 140, which will be described later, may be installed near the pipe 121. By the facility such as the pressure sensor 124, the monitoring camera 130, the speaker 140, when the transmission attempt grasps the pipe 121, the control center 150 immediately recognizes this, the speaker 140 ), A warning sound can be generated and the management personnel can be immediately added. Thereby, the transmission of the attempting sender can be more effectively prevented.
또한, 도 7에 도시된 바와 같이, 이러한 파이프(121)의 외주면에는 파이프(121)의 길이방향을 따라 복수개의 블레이드가 설치될 수 있다. 블레이드에 따르면, 투신시도자가 파이프(121)을 파지하는 것이 더욱 어렵게 되어, 투신시도자의 투신시도가 더욱 효과적으로 저지될 수 있다.In addition, as illustrated in FIG. 7, a plurality of blades may be installed on the outer circumferential surface of the pipe 121 along the longitudinal direction of the pipe 121. According to the blade, it is more difficult for the throwing attempter to hold the pipe 121, so that the throwing attempt of the throwing attempt can be more effectively prevented.
한편, 이러한 블레이드는 도 7에 확대부분에 도시된 바와 같이, 파이프(121)의 외주면의 접선 방향에 수직하는 방향에 대해 기울기를 가지며, 단부측에서 절곡될 수 있다. 이러한 블레이드의 형상에 따르면, 투신시도자가 파이프(121)를 파지하는 것이 사실상 불가능하게 되므로, 투신시도자의 투신시도가 더욱 효과적으로 저지될 수 있다.On the other hand, such a blade has an inclination with respect to the direction perpendicular to the tangential direction of the outer circumferential surface of the pipe 121, as shown in the enlarged portion in Figure 7, it can be bent at the end side. According to the shape of such a blade, since it is virtually impossible for the throwing viewer to grip the pipe 121, the throwing attempt of the throwing viewer can be more effectively prevented.
이러한 블레이드가 파이프(121)에 설치되는 경우, 파이프(121)는 블레이드가 설치되지 않을 때의 파이프(121)의 직경 보다 더 작은 직경으로 마련되어야 하는데, 이에 따르면, 파이프(121)의 제작 비용이 크게 절감되는 효과가 있다.When such a blade is installed in the pipe 121, the pipe 121 should be provided with a diameter smaller than the diameter of the pipe 121 when the blade is not installed, accordingly, the manufacturing cost of the pipe 121 is There is a significant savings.
또한, 이러한 블레이드가 파이프(121)에 설치되는 경우, 바람에 의해서 파이프(121)가 회전될 수 있다. 상술한 과정에 의해서 회전하는 파이프(121)에 전력충전모듈을 연결하면, 전력을 생산할 수 있는 효과도 기대될 수 있다.In addition, when the blade is installed in the pipe 121, the pipe 121 may be rotated by the wind. By connecting the power charging module to the rotating pipe 121 by the above-described process, the effect of producing power can also be expected.
또한, 이러한 파이프(121)에는 파이프(121)의 회전을 저지하는 브레이크수단(미도시)이 추가적으로 설치될 수 있다. 이러한 브레이크수단(미도시)은 파이프(121) 주변에 물체의 존재를 감지하는 근접센서(미도시)에 연동되도록 설치된다. 따라서, 파이프(121) 주변에 투신시도자가 존재하지 않는 경우에는 브레이크수단(미도시)이 작동하여 파이프(121)가 회전되지 않다가, 파이프(121) 주변에 투신시도자가 접근하면, 근접센서(미도시)가 이를 감지하여 브레이크수단(미도시)을 해제함으로써 파이프(121)가 회전될 수 있다. 상술한 과정에 따르면, 바람의 영향에 의해서, 파이프(121)가 회전하는 것이 효과적으로 방지되므로, 바람에 의해 파이프(121)가 회전하여 소음이 발생되는 문제가 효과적으로 예방된다.In addition, the pipe 121 may be additionally provided with brake means (not shown) to prevent rotation of the pipe 121. The brake means (not shown) is installed to interlock with a proximity sensor (not shown) that detects the presence of an object around the pipe 121. Therefore, when there is no transmission attempt around the pipe 121, the brake means (not shown) is operated to prevent the pipe 121 from rotating, and when the transmission attempt approaches the pipe 121, the proximity sensor ( The pipe 121 may be rotated by detecting this and releasing the brake means (not shown). According to the above-described process, since the pipe 121 is effectively prevented from rotating under the influence of the wind, the problem of the noise being generated by the pipe 121 being rotated by the wind is effectively prevented.
축(122)은 본체부(112)의 단부에 설치되는 것으로써, 상술한 내부공간에 배치되어 내부공간에 설치된 베어링(123)에 연결된다. 이러한 축(122)은 베어링(123)에서 본체부(112)의 단부를 향하는 방향을 따라 직경이 증가되도록 형성되어, 측면에서 보았을 때, 테이퍼(Taper)의 형태로 마련될 수 있다. (즉, 상측이 수평하고 하측이 기울기를 가지는 형상)The shaft 122 is installed at the end of the main body 112 and is connected to the bearing 123 disposed in the interior space and installed in the interior space. The shaft 122 is formed to increase in diameter along the direction from the bearing 123 toward the end of the main body 112, and when viewed from the side, it may be provided in the form of a taper (Taper). (That is, the shape of which the upper side is horizontal and the lower side is inclined)
이러한 축(122)의 형상에 따르면, 외부에서 축(122)의 상측면으로 유입되는 유체가 축의 하측의 경사면을 따라 본체부(112) 측으로 용이하게 유출될 수 있다. (한편, 외력에 의해 축(122)이 회전되었다가 외력이 제거되는 경우, 축(122)의 하측 부분의 자중에 의해서 축(122)은 상측이 수평하고 하측이 기울기를 가지는 형태로 자연스럽게 재배치 됨)According to the shape of the shaft 122, the fluid flowing from the outside to the upper side of the shaft 122 can easily flow out to the body portion 112 side along the inclined surface of the lower side of the shaft. (On the other hand, when the shaft 122 is rotated by an external force and the external force is removed, the shaft 122 is naturally relocated in a form in which the upper side is horizontal and the lower side is inclined due to the weight of the lower portion of the shaft 122. )
이러한 축(122)의 형상에 의하면, 외부에서 물질, 즉, 빗물, 습기, 눈 등이 축(122)을 따라 내부공간으로 침투하는 경우, 축(122)의 직경의 변화에 의해서, 즉, 축(122)의 경사면에 의해서, 외부의 물질이 내부공간으로 침투되지 못하고, 경사면을 따라 다시 외부로 용이하게 빠져나갈 수 있다. 이에 의해서, 겨울철 베어링(123)이 결빙되어 파이프(121)가 회전되지 못하는 현상이 효과적으로 방지된다.According to the shape of the shaft 122, when a substance, that is, rainwater, moisture, snow, etc., penetrates into the inner space along the shaft 122 from the outside, the shaft 122 is changed by the diameter of the shaft 122, that is, the shaft By the inclined surface of 122, the external material does not penetrate into the inner space, it can be easily escaped to the outside along the inclined surface. As a result, the phenomenon in which the winter bearing 123 is frozen and the pipe 121 does not rotate is effectively prevented.
베어링(123)은 내부공간에서 회전가능도록 축(122)에 연결되는 것으로써, 상술한 파이프(121)의 내주면에 접촉된다. 이러한 베어링(123)에 의해서, 투신시도자가 파이프(121)의 외면을 파지하는 경우, 파이프(121)가 용이하게 회전될 수 있다.The bearing 123 is connected to the shaft 122 so as to be rotatable in the inner space, and is in contact with the inner circumferential surface of the pipe 121 described above.
