[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding door support member. More specifically, the present invention relates to an improvement in versatility of a folding door support member that is attached to a hanging base fixed type folding door.

[0002]

2. Description of the Related Art Conventionally, for example, a structure shown in FIG. 4 is known as a structure for supporting a folding door.

In this conventional structure supporting a folding door, a folding door A on the moving side and a folding door B on the hanging side are connected by a hinge C, and an upper rail D and a lower rail E are respectively attached to the upper and lower ends of the folding door A on the moving side. The runners F and G, which slide in the inside of, are installed, and the upper rails D and
The pivots J and K that are rotatably fitted to the brackets H and I fixed to the lower rail E are attached.

[0004]

In the above-mentioned conventional structure supporting the folding door, the runners F and G attached to the upper and lower ends of the folding door A on the moving side are common, but the folding door B on the hanging side is common. The pivots J and K attached to the upper and lower ends are not commonly used due to the presence or absence of load on the folding doors, and three types of members are required as support members to be attached to the folding doors A and B. Therefore, there is a problem that the manufacturing cost of the supporting members attached to the folding doors A and B increases.

Further, runners F, G, pivots J, K
Since some of the parts are made common to be mounted on the folding doors A and B by a common embedded mounting structure, if the mounting position of each member is incorrect, a predetermined function cannot be achieved. For this reason, there is a problem that the member management and the mounting work of the supporting members mounted on the folding doors A and B are troublesome.

The present invention has been made in consideration of the above problems, and supports for folding doors in which the supporting members attached to the upper and lower ends of the folding door on the moving side and the folding door on the hanging side are all common. An object is to provide a member.

[0007]

In order to solve the above problems, the folding door support member according to the present invention employs the following means.

That is, according to the first aspect of the present invention, there is provided a bottomed cylindrical holder which is embedded and fixed in the folding door, and a slider which is housed in the holder so as to be prevented from rotating and slidable in the axial direction.
A spring member that is housed inside the holder and elastically presses the slider toward the tip, a shaft portion that has a slide shaft with a non-circular cross-section on the tip side and a screw shaft that engages with the slider on the rear end side, and the holder Of the shaft portion and slidably penetrating only the slide shaft of the shaft portion, a rotation adjustment portion provided slidably through the slide shaft of the shaft portion on the tip side of the cap portion, and And a head that is provided at the tip of the slide shaft and that directly or indirectly abuts on the rail.

According to a second aspect of the present invention, in the folding door supporting member according to the first aspect, the head portion is rotatable with respect to the shaft portion via the rolling member.

[0010]

According to the above-mentioned means, according to the first aspect of the invention, the rotation adjusting portion is rotated with the weight of the folding door being applied and the spring material being compressed, whereby the screw shaft of the shaft portion and the slider are screwed together. The length can be changed, and the distance between the folding door and the rail is adjusted by changing the protruding length of the slide shaft of the shaft portion from the holder. Therefore, it can be attached and used at the lower end of the folding door on the hanging side. When the elastic force of the spring material is applied to the head through the slider and the shaft without applying the weight of the folding door, the head comes into pressure contact with the rail. Therefore, it can be used by being attached to the upper and lower ends of the folding door on the moving side and the upper end on the hanging side.

According to a second aspect of the present invention, in the operation of the first aspect, the friction of the rotation of the head with respect to the rail and the sliding traveling is reduced.
