[Prior Art] Among conventional sliding door devices, there is known a sliding door device in which two moving doors are closed in a sliding state and then moved along a wall surface or a fixed door to be opened. This type of sliding door moved two doors each as it opened and closed.

[Problems to be Solved by the Invention] By the way, it has been very troublesome for a physically handicapped person, an elderly person, a child or the like to move two doors. As a mechanism for transmitting the driving force to one door to other doors, it is known as an elevator door, but since it has a complicated structure and uses a drive cylinder for either opening or closing,
It was not available at home.

Therefore, the present invention was developed to meet the above-mentioned demand based on the above-mentioned circumstances, and the two wires are used to transmit the driving force to one door to the other door for convenient opening and closing. The purpose is to provide the sliding door device.

[Means for Solving the Problems] A sliding door device for a physically handicapped person according to the present invention to achieve the above object is a first and a second door in a separated state between an upper part of a wall surface and an upper part of an outer door separated from the wall surface. The fixtures are arranged as a pair, and two pulleys, a first and a second pulley, are horizontally rotatably provided at both upper ends of the inner door approaching the wall surface and the like. And a second two wires are laid around and cross-pulled, and the crossing ends of the respective wires are tensioned and fixed to the respective fixtures of the wall surface and the outer door upper part separately. Is.

[Operation] The two wires are fixed at their one ends to the fixtures that are separated from each other at the upper part of the outer door, crossed close to each other in the middle, then hung from the pulleys at the both ends of the inner part of the door from the outside, and further crossed. The other end is fixed to each fixing tool which is separated from the wall or the upper part of the fixed door. The wires are in a proper tension.

For example, when an opening force is applied to the closed outer door, the second wire is rotated by the second pulley of the inner door to transmit the moving force to the inner door in the opening direction. Therefore, the inner door is opened at the same time with the opening operation to the outer door.

In this case, since the first pulley moves as the inner door moves, the first wire is delivered in a tensioned state.

On the other hand, when the sliding door in the opened state is closed, if a moving force is applied to the outer door, the closing force is transmitted to the inner door via the first wire, so the inner door is also closed at the same time. . In this case, the second wire is paid out as the second pulley moves.
