Description

  The present invention belongs to the technical field of a sliding door device of a lower rail traveling type that opens and closes the entrance / exit provided on the end face of the vinyl house, and further, prevents the sliding door from being lifted off from the lower rail due to strong wind. The present invention relates to a sliding door device provided with a mechanism or structure.

2. Description of the Related Art Conventionally, the sliding door device used at the entrance and exit of a vinyl house is mainly a suspended type in which a sliding door is suspended from an upper rail by a door wheel. The reason is that the lower rail is easily soiled with mud and dirt on the ground, and is often stepped on by a person or a wheel to bend, and has a problem that the sliding movement is likely to be hindered. However, there is an advantage that the mounting work and the maintenance work are easy.
Since the present applicant has applied for a sliding door device that solves the above-described problems and utilizes the advantages of the sliding door device of the lower rail traveling type, it has been disclosed as Patent Document 1 below.

In the sliding door device described in Patent Document 1, as shown in FIG. 12, the lower rail 40 has a substantially hat-shaped steel cross-sectional shape, and the horizontal leg portions 40a at the lower portions on both sides thereof are convex on the ground. A door wheel 43 is mounted on the lower rail 40 and is mounted in a hollow portion of a groove-shaped steel lower frame 42 that forms the lower side of the sliding door 41, and the lower frame 42 is used. A rail guide member 44 that guides the traveling of the door pulley 43 is fitted into the end of the rail. Therefore, even if mud or garbage falls on the convex portion 40b of the lower rail 40, it usually rolls down to the lower leg portion 40a. Even if mud or garbage adheres to the convex portion 40b, once the door pulley 43 travels on the lower rail 40 and passes through, it will not be crushed or pushed away by its weight and will not interfere with the subsequent travel. .
Moreover, the structure which can attach / detach the length part in the range of the opening width of the entrance / exit of the lower rail 40 as needed, is easy to enter / exit a tractor etc., and prevents the lower rail 40 from being stepped on and bent is described. Yes.
Japanese Patent Laid-Open No. 11-243790

In the invention of Patent Document 1 described above, the lower rail 40 is made of a hat-shaped steel formed of horizontal leg portions 40a and convex portions 40b that are low on both sides. This is a lower rail traveling type sliding door device that prevents the opening and closing of the sliding door from being obstructed.
However, the lower rail travel type sliding door device has a configuration in which the lower frame 42 of the sliding door 41 is slid by the door cart 43 in an open state without any restriction. Therefore, if a strong wind blows against the sliding door 41 when the sliding door 41 is fully closed, the vinyl sheet is subjected to wind pressure and the whole becomes easy to tilt. Then, it has been pointed out that the sliding door 41 having a weak restraining force against the wind pressure easily floats and the lower frame 42 may be detached from the lower rail 40 at the end. If the sliding door 41 is removed, a strong wind will like the inside of the vinyl house, which not only adversely affects the crops in the vinyl house, but also causes the entire vinyl house to collapse.
