The operation panel 210 is provided with a rubber plate 212, A pair of fixed rods 220 on which a spring 222 is mounted and a pair of fixed rods 220 disposed on both sides of the operation gap 210 to limit the gap leftward and rightward, And a fixing table 230 integrally formed on both sides of the rear surface of the door 20.

The locking part 300 is installed in the elevating car door 10 and the landing door 20 and the rail 22 of the landing platform so as to prevent the landing door 20 from being opened, And the lift door 20 can be raised and lowered at the same time when the lifting and lowering door 10 and the lift door 20 are lifted up and down. A link 320 that is hinged to the operation bar 310 and moves to the left and right and has a footing roller 322 at an end thereof; A rotary plate 330 hinged to one side of the lower portion of the elevating car door 10 so as to be moved forward and backward by a roller 322, A lower portion of which is hinged to a rail 22 mounted on a platform, And a hook 350 protruding from one side of the lower portion of the landing door 20 so as to be hooked on the hook 340.

Here, the reference numeral 400 denotes a sensing sensor, which is installed on the upper part of the elevator car 1, detects the upward movement of the elevator car door 10 and the landing door 20 by a predetermined height, So that it can be rotated in the reverse direction.

The operation of the automatic opening and closing device of the door for the elevator door of the upper and lower opening type according to the present invention having the above-described various configurations is as follows: when the elevator car 1 is lifted up and reaches the target floor, And drives the driving unit 100 integrally connected by the first chain C1 and the second chain C2.

The operation of the driving unit 100 is such that the first sprocket 110 and the third sprocket 130 in which the first chain C1 is wound rotate at the same time by 90 degrees in the forward direction and the third sprocket 130, When the second sprocket 120 connected to the second chain C2 is simultaneously rotated by 90 degrees, the spacing rods 112 protruding forward of the first and second sprockets 110 and 120 are perpendicular So that the operation unit 200 is operated by sliding the operation units 114 and 124 to the left and right.

The action of the actuating part 200 is such that the actuation rod 114 and 124 are slid to the left and right by the actuation of the actuating part 100 to move the actuating rod 210 supported by the fixed rod 220 to the left / When the operation unit 210 is stopped by the fixing table 230, the operation unit 114 and the operation unit 210 are closely and tightly coupled to each other, And the landing door 20 are integrated.

The operation of the locking part 300 operating at the same time is such that when the second sprocket 120 of the driving part 100 rotates by 90 degrees, the actuating bar 310 and the link 320 are moved to the left side, The pushing roller 322 installed on the hook 320 pushes the rotary plate 330 to rotate forward and the rotary plate 330 is pivoted so that the moving roller 342 installed on the hook 340 is pushed forward, When the locking part 300 is released from the locked state, the driving motor M is driven to rotate by the rotation of the driving motor M, The elevating car door 10 and the landing door 20 simultaneously rise and the front of the elevating car 1 is opened.

At this time, when the elevating car door 10 and the landing door 20 are raised and stopped, the detection sensor 400 senses it and drives the driving motor M inversely to be connected to the first chain C1 The second sprocket 120 connected to the first and third sprockets 110 and 130 and the second sprocket 130 and the second chain C2 is rotated in the opposite direction to rotate the sprocket rod 122 vertically The operation space 210 opened by the elasticity of the spring 222 mounted on the fixing rod 220 moves to the center and returns to the original position, The elevating car door 10 and the landing door 20, which are integrally separated from each other, are separated from each other between the operating space 210 and the operating pedestals 114 and 124, which are in close contact with each other.

The reason why the elevating car door 10 and the landing door 20 are elevated at the same time to be opened and then separated from each other is that when the cargo loaded on the elevator car 1 is lowered or mounted, When the elevator car door 10 and the landing door 20 are integrated with each other, the driving unit 100 or the operation unit 200 may be damaged or malfunctioned, It is necessary to separate the elevator car door 10 and the landing door 20 from each other when the elevator car 1 is to be mounted or lowered.

That is, the operation unit 210 of the driving unit 100 is closely contacted with the operation unit 210 of the operation unit 200, so that the elevation car door 10 and the landing door 20 are integrated When the cargo is mounted on the elevator car 1, the elevator car 1 is lowered by the load, and the elevator car door 10 and the landing door 20 are simultaneously sagged by the height The elevator car 1 is lifted or lowered in a state in which the elevator car door 10 is not completely closed when the elevator car door 10 and the landing door 20 are lowered at a later time to cause a safety accident There is a concern.

The first and third sprockets 110 and 130 and the second sprocket 120 are rotated in the reverse direction when the driving motor M is continuously rotated in the reverse direction The separation rods 112 and 122 provided on the first and second sprockets 110 and 120 are again horizontally positioned so that the operating rods 114 and 124 are moved to the left The operation unit 210 is slid to the fixing table 230 in a state in which the operation unit 210 is supported by the fixing rod 220 and the spring 222, So that the elevator car door 10 and the landing door 20 are integrated again.

The elevating car door 10 and the landing door 20 are integrated with each other and the driving motor M is continuously rotated in the reverse direction so that the elevating car door 10 and the landing door 20 are simultaneously lowered The driving motor M is rotated 90 degrees in the forward direction to return the driving unit 100 and the actuating unit 200 to the home position.
