Description

도파로 시트를 이용한 엘리베이터 도어의 손 끼임 방지용 안전장치 Safety device to prevent hand pinching of elevator door using waveguide seat
본 발명은 도파로 시트를 이용한 엘리베이터 도어의 손 끼임 방지용 안전장치에 관한 것으로서, 좀더 상세하게는 엘리베이터의 승장도어 또는 카도어가 개방중에 손이 끼는 경우 상해를 입히지 않도록 승장도어 또는 카도어의 개폐를 제어하면서 사용자가 시각적으로 손 끼임에 대한 경각심을 가질 수 있도록 시각정보를 표시하는 도파로 시트를 이용한 엘리베이터 도어용 손가락 끼임 방지장치에 관한 것이다.The present invention relates to a safety device for preventing hand pinching of an elevator door using a waveguide sheet, and more particularly, to control the opening or closing of an elevator door or a car door so as not to cause injury if the elevator door or the car door is caught during opening. While the present invention relates to an elevator door pinching prevention device using a waveguide sheet for displaying visual information so that a user may have a vigilance about hand pinching.
일반적으로 엘리베이터는 내부에 승객이 탑승한 상태에서 건물 내부에 수직방향으로 형성된 승강로를 따라 상ㆍ하방향으로 이동하면서 탑승객을 이동시키는 엘리베이터 카와, 소정 동력을 발생시키는 모터 및 권상기와, 승객의 버튼 조작에 따라 상기 모터 및 권상기를 제어하여 상기 엘리베이터 카를 해당 층으로 이동시키는 제어수단 등을 포함하여 구성된다.In general, an elevator is an elevator car that moves passengers while moving up and down along a hoistway formed in a vertical direction inside a building, a motor and a hoist that generates predetermined power, and a button operation of a passenger. And control means for controlling the motor and the hoist to move the elevator car to the floor.
그리고, 상기 엘리베이터 장치에 구비되는 엘리베이터 카에는 선택적으로 개폐되는 카도어가 구비됨과 아울러, 건물의 각층 승강장에는 상기 카도어와 연동하여 개폐되면서 탑승객을 해당 층에 승하차 시킬 수 있도록 하는 승장도어가 설치된다.In addition, the elevator car provided in the elevator device is provided with a car door that is selectively opened and closed, and the landing door is installed on each floor of the building to allow the passengers to get on and off the floor while interlocking with the car door. .
이때, 승장도어는 승장도어의 열림 및 닫힘이 원활히 수행되도록 승장프레임과 승장도어 사이에 틈이 존재해 탑승자가 엘리베이터에 탑승하기 위해 승강장에서 대기시 손을 승장도어의 틈 주위에 대고 있는 상태에서, 승장도어가 열리는 것을 인식하지 못할 경우, 손을 미처 승장도어로부터 떼지 못해 승장도어와 승장프레임 사이의 틈으로 손이 끼게 되어 상해를 입게 되는 문제점이 있었다. 특히, 어린아이의 경우에는 주의력이 부족하므로 승장프레임과 승장도어 사이에 손이 끼어 다치게 되는 안전 사고의 우려가 많았다.At this time, the landing door has a gap between the landing frame and the landing door so that the opening and closing of the landing door can be performed smoothly, while the passenger is waiting at the landing hall to board the elevator, while holding his hand around the gap of the landing door. If it does not recognize that the door is opened, the hand could not be removed from the door, the hand was caught in the gap between the door and the lift frame, there was a problem that injuries. In particular, in the case of children, attention was lacking, so there were many concerns about safety accidents in which hands were injured between the landing frame and the landing door.
물론 이와 같은 문제점을 해소하고자 공개실용신안 제20-2010-0010939호가 제시된 바 있다. 이는 엘리베이터의 손끼임 방지 장치에 관한 것으로, 상부프레임과 좌측프레임 및 우측프레임으로 이루어진 고정부 내에 카도어 및 승장도어가 설치되어 구성되는 엘리베이터 도어에 탑승객의 손이나 이물질 등이 끼이는 것을 방지하기 위한 장치에 있어서, 상기 승장도어 및 카도어의 외면과 대응되는 상기 상부프레임의 양단부 측 내벽면에는 하측을 향해 수직으로 검출광을 발산하는 물체 반사식 센서로 이루어진 상부프레임 좌측센서 및 상부프레임 우측센서가 각각 한 쌍씩 설치됨과 아울러, 상기 승장도어 및 카도어의 외면과 대응되는 상기 상부프레임 중앙의 내벽면에는 하측을 향해 수직으로 검출광을 발산하는 물체 반사식 센서로 이루어진 한 쌍의 상부프레임 중앙센서가 설치되어 구성되어, 엘리베이터 도어의 개폐 동작 시에 승객의 손이나 각종 이물질 등이 끼이는 것을 방지할 수 있다.Of course, in order to solve such a problem, Korean Utility Model Publication No. 20-2010-0010939 has been proposed. The present invention relates to a device for preventing hand pinching of an elevator, and to prevent a passenger's hand or a foreign object from being caught in an elevator door formed by installing a car door and a landing door in a fixing part including an upper frame, a left frame, and a right frame. In the apparatus, an upper frame left sensor and an upper frame right sensor made of an object reflection sensor which emits detection light vertically downward on both inner side surfaces of the upper frame corresponding to the outer surfaces of the boarding door and the card door. A pair of upper frame center sensors each including a pair of object reflection sensors which emits detection light vertically downwards on the inner wall of the center of the upper frame corresponding to the outer surfaces of the boarding door and the card door, respectively. Installed, the passenger's hand during the opening and closing operation of the elevator door The various debris that caught can be prevented.
그런데, 상기 공개실용신안은 검출광의 검출을 통해 손이나 이물질을 감지하는 구조로 예를 들어 도어의 개폐에 영향을 주지 않는 박스나 가방 등이 도어에 접근하는 경우에도 이를 감지하여 도어의 개폐를 임의로 제어하게 되므로 특정 상황에서의 강제적인 도어의 개폐 제어가 빈번해져 승객에게 불편할 뿐만 아니라 다수의 센서를 상부프레임 등에 설치해야 하므로 구조적으로 복잡한 문제를 안고 있다.However, the public utility model is a structure that detects a hand or a foreign object through the detection of the detection light, for example, even if a box or a bag that does not affect the opening and closing of the door detects this to arbitrarily open or close the door. Since the control of the door is forced to open and close frequently in a specific situation, it is inconvenient for passengers, and also requires a large number of sensors to be installed in the upper frame, which poses a structural problem.
한편, 상기 공개실용신안의 문제점을 해결하기 위해 일본 공개특허공보 특개제2009-515798호가 제안된 바 있다. 이는 도어 어셈블리에 관한 것으로, 도어패널(22) 또는 리턴패널(24)의 표면 또는 엣지면에는 전기전도성 필름 등으로 이루어지는 센서(30, 30',32)가 구비되고, 도어 프레임부재(26)에도 동일한 구조의 센서(34)가 구비된다. 따라서, 도어패널(22) 또는 리턴패널(24)의 표면 또는 엣지면에 손이 접촉되어 인체의 전류가 감지되면 도어패널(22) 또는 리턴패널(24)의 개폐를 강제 제어하여 손이 엘리베이터 도어와 프레임 사이에 손이 끼어 다치는 것을 방지한다.On the other hand, Japanese Laid-Open Patent Publication No. 2009-515798 has been proposed to solve the problems of the above-mentioned utility model. This relates to a door assembly. Sensors 30, 30 ', 32 made of an electrically conductive film and the like are provided on the surface or the edge of the door panel 22 or the return panel 24, and the door frame member 26 is also provided. The sensor 34 of the same structure is provided. Therefore, when a hand is in contact with the surface or the edge of the door panel 22 or the return panel 24 and the current of the human body is sensed, the hand is controlled by forcibly controlling the opening and closing of the door panel 22 or the return panel 24. Avoid getting your hands caught between the frame and the frame.
그런데 상기 공개실용신안은 단순히 인체가 감지되면 도어를 개폐하여 다치는 것을 방지할 수 있을 뿐, 도어에 직접 경고나 비상상태 등의 시각적 정보는 제공하지 않아 엘리베이터가 정전으로 인해 등기구가 소등되는 경우에는 승객 자신이 서있는 위치 판별이 어려워 당황하는 등의 문제가 있다.By the way, the public utility model can only prevent the injury by opening and closing the door when a human body is detected, and does not provide visual information such as a warning or emergency state directly to the door, so if the luminaire is turned off due to power failure, There is a problem such as being difficult to determine the standing position of yourself.
한편, 통상의 엘리베이터는 도어에 기대는 것을 방지하고 과적을 방지하기 위해 '승강기시설 안전관리법'에 의해 승장도어와 카도어의 하단에서 170~180㎝의 높이에 "손대지 마시오","기대면 추락위험"이 인쇄된 주의사항 스티커를 부착하도록 강제하고 있다. 하지만, 이와 같은 주의사항 스티커는 제작 후 카도어 뿐 아니라 모든 층의 승장도어에 부착해야 하므로 많은 수의 주의사항 스티커를 부착하는데 소요되는 비용이 많이 소요되고, 부착된 주의사항 스티커의 분실 및 훼손 등으로 인한 유지관리에 필요한 비용과 인력 투입으로 인한 시간이 많이 소요되고, 엘리베이터의 미관 역시 저해하는 문제점도 있다.On the other hand, in order to prevent the elevator from leaning against the door and to prevent overloading, the elevator does not touch the floor at the height of 170 to 180 cm from the lower of the landing door and the car door according to the Elevator Safety Management Act. It is compulsory to attach a caution sticker printed with "Danger". However, since these precautionary stickers need to be attached to the boarding doors of all layers as well as to the car door after manufacturing, it takes a lot of money to attach a large number of precautionary stickers, and the loss and damage of the attached precautionary stickers Due to the cost and time required for maintenance due to the maintenance of manpower takes a lot, there is also a problem that inhibits the aesthetics of the elevator.
이러한 종래 기술의 문제점을 해결하기 위한 것으로서, 본 발명은 엘리베이터 도어인 승장도어 또는 카도어의 표면에 손이 접촉되어 인체의 전류가 감지되면 엘리베이터 도어의 개폐를 강제 제어하여 손이 엘리베이터 도어와 프레임 사이에 손이 끼어 다치는 것을 방지함은 물론 시각적 정보를 도어 등의 표면에 직접 표시하여 신속하고도 침착한 대응을 할 수 있도록 유도하는 도파로 시트를 이용한 엘리베이터 도어의 손 끼임 방지용 안전장치를 제공하는데 그 목적이 있다.The present invention is to solve the problems of the prior art, the present invention when the hand is in contact with the surface of the elevator door or the car door which is an elevator door when the current of the human body is sensed by forcibly controlling the opening and closing of the elevator door between the elevator door and the frame To provide a safety device for preventing hand pinching of elevator doors using a waveguide sheet that not only prevents hands from getting injured but also displays visual information directly on surfaces such as doors for quick and calm response. There is this.
또한 본 발명은 엘리베이터가 정전으로 인해 카 내부의 등기구가 소등되는 경우에도 승객이 도어의 위치 등을 용이하게 판별할 수 있음은 물론 도어에 주의사항 스티커 등을 부착할 필요가 없어 미관 저하를 방지하고 다양한 문양 등의 시각적 정보를 표시할 수 있는 도파로 시트를 이용한 엘리베이터 도어의 손 끼임 방지용 안전장치를 제공하는데 그 목적이 있다.In addition, the present invention can easily determine the position of the door even when the luminaire inside the car is turned off due to the blackout of the elevator, as well as it does not need to attach a caution sticker to the door to prevent aesthetic degradation An object of the present invention is to provide a safety device for preventing hand pinching of an elevator door using a waveguide sheet capable of displaying visual information such as various patterns.

또한, 도 11은 본 발명의 또 다른 실시 예를 도시한 도면으로, 도어용 전도성 도파로시트(130)와 프레임모서리용 전도성 도파로시트(140)는 표면적이 넓어 테두리 일측에만 제1 및 제2LED(150,152)만을 구비하면 빛의 이동거리가 길어져 빛의 확산 효율이 낮다. In addition, FIG. 11 is a view showing another embodiment of the present invention.
