Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an upper frame structure of an upper hanging sliding door in which a curtain plate for preventing, for example, upper light leakage can be easily and reliably attached.

[0002]

2. Description of the Related Art An upper hanging sliding door can have a flat floor surface without a threshold and rails so that there is almost no sweeping area of a door plate such as a hinged door and no dead space is generated, and in order to be barrier-free. In view of the above, its advantages are being recognized again.

[0003]

The upper hanging door is mounted on a flange of a rail attached to the door through a connecting rod fixed to hanging metal fittings at both ends in the running direction of the upper part of the sliding door. The wheels fixed to the runners on both sides rotatably roll, so that they run in a direction parallel to the plate surface and are opened and closed. The upper part of the hanging door
A portion other than the connecting rod fixed to both ends in the traveling direction between the lower surface of the rail and the rail is a gap extending in the traveling direction. There is a problem that light leaks from this gap.
Further, when the rail is attached to the lower surface of the upper frame member in a state where the rail protrudes so as to extend in the longitudinal direction, the rail member is visually recognized from the outside, and it is unsightly.

In order to solve such a problem, a curtain plate is attached to the front and back of the rail along the rail so as to cover the gap and the lower part of the rail. Conventionally, as shown in FIG. 3, in order to attach the curtain plate, a groove is formed on the lower surface of the upper frame 1 along the longitudinal direction of the Kamoi rail 5, and the curtain plate 4 is fitted into the groove. The method of attachment was adopted.
According to this method, if the engagement between the groove and the curtain plate 4 is too tight, it is difficult for the curtain plate 4 to enter the groove, and if the engagement is poor, the curtain plate may fall off until the adhesive is hardened. For example, it is not only difficult to attach the curtain plate to the lower surface of the upper frame, but also it requires time and effort. Therefore, in many cases, the curtain plate 4 needs to be manufactured with high dimensional accuracy by injection molding of a synthetic resin. In FIG. 3, reference numeral 2 denotes a casing mounting groove, and reference numeral 6 denotes an upper hanging sliding door.

SUMMARY OF THE INVENTION An object of the present invention is to provide an upper frame structure for a sliding door in which a curtain plate can be easily and simply attached to an upper frame.

[0006]

According to a first aspect of the present invention, there is provided an upper frame structure of an upper hanging sliding door, wherein a casing material is provided on at least one side in a cross-sectional width direction of the upper frame. The horizontal portion of the sliding door and the horizontal portion of the curtain plate are formed with a concave groove having a U-shaped cross section in a dimension to be fitted tightly.

According to a second aspect of the present invention, there is provided an upper frame structure of the upper hanging door, wherein the casing material and the curtain plate have a horizontal T-shaped cross section on at least one side in the cross-sectional width direction of the upper frame. An upper frame structure of a sliding door, characterized in that a concave groove having a U-shaped cross section is formed so as to have a dimension into which a horizontal portion of the integrated molded product is fitted tightly.

[0008]

According to the present invention, since the present invention has the above-described configuration, the installation of the curtain plate is simple and easy, and the labor is reduced. Further, the curtain plate can be easily made of a wooden material. Therefore, it is not necessary to use a synthetic resin injection molded product, and in that case, a mold cost is unnecessary, and there is no problem such as a small amount that does not fit a synthetic resin injection molded product lot.
