Description

Safety device to prevent hand pinching of elevator door using waveguide seat

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.

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.

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. .

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.

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.

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.

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.

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.

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.

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.

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.
