DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sliding door in which a door is held by a hanging support, and more particularly to a non-rail sliding door which does not require a rail to guide the door on a road surface.

[0002]

2. Description of the Related Art Conventionally, rollers are provided at upper and lower positions of a hanging post which serves as a hanging support, and a door body is sandwiched between these rollers from above and below so that the door can be moved with respect to the hanging post. Non-rail sliding doors have been proposed (JP-A-8-86).
169). In such non-rail sliding doors, the door body is held only on the hanging post, so the door body can be opened and closed regardless of the unevenness of the road surface. It could be shortened. Also, since there is no step caused by rails in the passage section opened and closed by the door body, it is attracting attention as a product suitable for barrier-free use.

However, the non-rail sliding door has a drawback in that when the door body is moved to the maximum, the rotation moment of the door body around the suspension column becomes large and the tip of the door body hangs. In particular, when closing the passage portion, a positional shift occurs between the locking device provided at the door stop end of the door body and the lock receiving member provided on the door stop pillar, making the locking operation difficult, There was a risk of damaging the device.

One of the causes of the hanging at the tip of the door body of the non-rail sliding door is, as shown in FIG. 7, in the door body A in which the vertical frame B and the horizontal frame C are framed in a rectangular shape, the vertical frame B Since the side frames C are normally connected by screw means, the doors A are distorted by the weight of the doors A themselves when they originally have the shape indicated by the thick line X. When such a door body A is pinched and moved by rollers positioned above and below the hanging support, rattling due to the influence of the distortion of the door body A occurs between the door body A and the roller, A dripping occurred at the tip of A. Such a phenomenon of the tip of the door body is also caused by insufficient rigidity of the door body itself. Therefore, it is conceivable to integrally form the frame of the door body by welding or casting. In addition to the increase in the cost of materials and the number of manufacturing steps, the weight of the door body becomes too large, which is not suitable for practical use.

[0005] The applicant of the present patent application is Japanese Patent Application Laid-Open No. 9-217572.
As shown in the publication, in order to prevent the door body of the non-rail sliding door from hanging, there has been proposed a non-rail sliding door provided with a door lifting member interlocked with the movement of the door body. According to this, although the tip of the door body can be prevented from sagging when the door body is moved, a separate door body lifting member for pushing up the door body itself is required. It was unsuitable for a sliding door gate.
