2. Description of the Related Art A sliding door is usually provided with a rail on the floor to guide the lower part of the sliding door even if the sliding door is hung above the rail. Pedestrians' feet get stuck in the projecting objects, which impacts wheelchairs, luggage vehicles, and the like. Grooves have few drawbacks, but foreign matter accumulates and interferes with the opening and closing of the sliding door. Therefore, it is desirable that the floor of the doorway is flat. Some of the single sliding door devices have a lower guide device inside the door pocket to make the floor flat, but in the double sliding door device, one of the sliding doors is the entire door bag when closed. It cannot be processed in the door pocket because it is located away from the unit (door storage part).

Further, when electric insulation is required for people passing by as a countermeasure against electricity, the fact that the rails are conductors on the floor has a drawback that the insulation measures are not easy.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to eliminate a protruding rail or a groove for guiding a lower part of a sliding door on a floor of a passage of a sliding door device which has been conventionally provided, and to obtain a flat floor. In particular, it is an object to achieve it in a double sliding door device which has never been seen before. Also, facilitating electrical insulation of the floor is another issue.

[0005]

SUMMARY OF THE INVENTION The present invention provides a double sliding door device in which a sliding door is hung at an upper portion, and a first guide groove is provided at a lower portion of the first sliding door having the shorter stroke of the double sliding door. Having a second guide groove, the first guide groove has a downward shape, and the first guide element protruding from the floor is engaged with the first guide groove to guide the lower part of the first sliding door, The second guide attached to the lower part of the second sliding door is engaged with the second guide groove so that the first sliding door guides the lower part of the second sliding door. By means of installing outside the opening range, or in a double sliding door device in which the sliding door is hung at the top,
In the lower part of the first sliding door with the shorter stroke of the double, there is a first guide groove, the first guide groove has a downward shape, and the first guider protruding from the floor is the first guide. It has a structure that engages with a groove to guide the lower part of the first sliding door, has a second guide groove in the lower part of the second sliding door with the longer stroke, and has a second guiding groove attached to the lower part of the first sliding door. The guide is engaged with the second guide groove so that the first sliding door guides the lower part of the second sliding door. Another means is to install the first guiding outside the opening range of the sliding door. And

[0006]

According to the above construction, the first sliding door is guided by the first guide member protruding from the floor, and the second guide groove of the first sliding door and the second sliding door attached to the second sliding door are provided. The second sliding door is guided to the first sliding door by the engagement of the guide element. That is, the second sliding door is indirectly guided through the first sliding door to the first guide element protruding to the floor. In another configuration, the first sliding door is guided by the first guider protruding from the floor, the second guide groove of the second sliding door and the second guider attached to the first sliding door. The second sliding door is guided to the first sliding door. That is, the second sliding door is indirectly guided through the first sliding door to the first guide element protruding to the floor. Therefore, only the first guider protrudes to the floor, and since the guider is outside the opening range of the sliding door, there is no protrusion on the floor of the passage and there is no groove for guiding.
