Description

DETAILED DESCRIPTION OF THE INVENTION (1) Technical Field of the Invention The present invention relates to a sliding door device having a structure in which a sliding door moves laterally and longitudinally when it is opened and closed, and particularly relates to a structure for preventing swinging of the sliding door. The sliding door mentioned above also includes a partition.

(2) Prior art and its problems Conventionally, in sliding door devices in which the sliding door moves in the lateral and front-back directions when opening and closing, the steady rest structure of the sliding door has been used in Japanese Patent Laid-Open No. 57-41908'4 and Japanese Patent Laid-Open No. 57-57- 16557
There is one described in Publication No. S.

(1) The steady rest structure of %Kaisei No. 57-119084 consists of a horizontally oblong guide hole drilled in the lower stile surface of the sliding door, and the central part of the sill (the part where the mating side of the sliding door is located when the door is closed). is equipped with a guide mechanism. This guide mechanism consists of a guide and a spring. The guide includes an arm that is movably fitted into the guide hole and an arm that receives the spring, and branched portions of both arms are rotatably attached to a support shaft that stands up on the sill. The proximal end of the spring is fixed to the sill.

However, the steady rest structure described above is a complicated structure in which the guide is rotated and the spring is elastically deformed as the sliding door moves backward.

Moreover, when the door is opened, the guide arm is still in contact with the end of the guide hole, so the outer edge of the outer stile of one sliding door can be moved to a position where it overlaps the outer edge of the other sliding door. Difficult to open the door. Therefore, the frontage when the door is opened cannot be enlarged.

(11) The steady rest prevention structure in the sliding door device disclosed in JP-A-57-16557 has two cylindrical protrusions with different diameters and lengths on the top and bottom of the sliding door, and two cylindrical protrusions corresponding to each of these protrusions. The structure is such that two substrates having grooves of different depths are provided, these different grooves intersect with each other at the center, and curved portions are provided at both ends.

Therefore, since the structure is such that the four protrusions are moved in parallel to the upper and lower grooves, the work of attaching each protrusion is troublesome. In other words, if the installation interval of the protrusions at upper F is slightly wider or narrower than the interval between the terminals of the curve υ section, the center of the protrusions will shift from the set center of the terminal of the curve 9, and the front and rear of the sliding door will Not only will you have to move around a lot, but the front of the sliding door won't close flush. For this reason, there is an inconvenience that four protrusions must be attached to one sliding door while adjusting the sliding door's forward and backward movement.

The above-mentioned meeting side refers to the tip side of the sliding door that moves laterally when opening.

In addition, the root side, which will be described later, is a sliding door that moves laterally to open the door (3) Purpose of the Invention In view of the conventional circumstances mentioned above, the purpose of the present invention is to maximize the opening width of the door by simplifying the steady rest. Our goal is to provide door equipment.
