Description

  The present invention relates to a joint structure of an upper rail for a hanging door for running a hanging door car such as a hanging sliding door and a folding door, and a construction method therefor.

  For example, as shown in FIG. 12, the folding door is a suspended door cart in which an upper rail 52 is disposed on the upper side of the opening, a lower rail 53 is disposed on the lower side, and is fixed to the upper end side of the folding door 50. 56 is guided along the upper rail 52, and the lower runner 57 fixed to the lower end of the folding door 50 is guided along the lower rail 53, so that the folding door 50 has an intermediate hinge 51. , 51 can be bent and opened at the boundary. The suspended sliding door is basically the same structure except that the door is not bent.

  As shown in FIG. 13, the upper rail 52 has a substantially groove-shaped cross section with a lower center opening in a slit shape, and has running portions 52 a and 52 a on which the rollers of the suspension door wheel 56 roll on both sides of the lower surface. It has a structure. Since the folding door 50 is attached by first attaching the upper rail 52 and the lower rail 53 to the opening, and then attaching the folding door 50, the upper rail 52 is made shorter by several tens of centimeters than the opening width. After the folding door 50 is suspended while the suspension door 56 is inserted from the opening of the end face, a short upper rail 55 is added to the upper rail 52, and the upper rails 52, 55 are provided over the entire width of the opening. ing.

  Therefore, there is a seam in the upper rails 52 and 55, and there is a problem that a rattling or an impact sound is generated when the hanging door car 56 travels if a slight step is generated at the seam position. .

  In order to solve such a problem, conventionally, as shown in FIG. 13 and FIG. 14 at the joint position of the upper rails 52 and 55, the inner rail side of the upper rail is straddled between both upper rails 52 and 55. Further, by inserting a joint member 54 obtained by processing a thin plate into a substantially groove-shaped cross-sectional shape, a gap between the upper rails 52 and 55 is eliminated so that no step is generated.

  Further, in recent years, as shown in Patent Document 1 below, the upper rail is installed in the opening in a state where the suspension door car is put in the upper rail in advance, and the fixing portion is provided on the hanging door, and the fixing portion of the hanging door is provided. There has been proposed an opening / closing body device that can be easily connected to a suspension door set on the upper rail. In the case of this opening / closing body device, since there is no seam in the upper rail, it is possible to completely eliminate rattling and impact noise during travel (see paragraph [0003]).
