DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a sliding door, for example.
The present invention relates to a two-dimensional adjustable hanging door car having a vertical adjustment mechanism and a front-rear direction adjustment mechanism at the same time in order to adjust a mounting position and a position where a hanging door can be smoothly opened and closed in a sliding sliding door, a folding door, and the like.

[0002]

2. Description of the Related Art This type of suspension door roller includes a traveling rail provided on a door frame, a runner body capable of traveling in the traveling rail, a runner mounting bracket fixed to an upper part of the suspension door, and It is composed of a connecting shaft for connecting the main body and the runner base, and most of them are provided with an appropriate vertical position adjusting structure for performing the mounting adjustment, for example, a screw portion is formed on the connecting shaft and screwed to the runner mounting bracket. The vertical position can be adjusted by adjusting the amount of penetration.

[0003]

As described above, many hanging door wheels are provided with a vertical adjustment mechanism so that the hanging door can be installed at a regular height at the time of construction.
Due to the failure of the mounting position of the running rail or the warping or deformation of the suspension door itself that occurs with time, there were cases in which the joint of the inner and outer shojis caused contact and collided. . In this case, the only way to correct these problems is to replace the warped or deformed suspension door with a new one, or change the mounting position of the traveling rail to adjust the position of the folding door in the front-rear direction.

[0004] On the other hand, in this type of hanging door, when a hanging door car is attached to a hanging door in advance in a factory or the like and transported, the hanging door car protruding outward from the hanging door is used when loading or unloading. In some cases, there is a problem that the door may be damaged, or when the hanging door wheel is mounted at the site in order to avoid such a situation, the mounting operation is troublesome.

Accordingly, a first object of the present invention is to provide a hanging door car itself with a vertical adjusting mechanism and a longitudinal adjusting mechanism so that the hanging door can be positioned at a proper mounting position with respect to the door frame. In addition, it is an object of the present invention to make it possible to easily adjust so as to eliminate contact or collision such as a combination.

[0006] A second problem is to reduce the labor required for installation work at the site and to prevent breakage during transportation by enabling the hanging door to be easily mounted on the hanging door.

[0007]

According to the present invention, there is provided a runner body having a plurality of rollers on its side and guided movably along a running rail, and fixed to an upper part of a suspension door. A runner mounting bracket, and a connecting shaft connecting the runner body and the runner mounting bracket, wherein the runner mounting bracket has a first elongated hole in a direction orthogonal to the traveling rail direction in plan view. Is formed, a slide block housing case through which the connection shaft is vertically penetrated through the first elongated hole, and is accommodated inside the case and is movable along the traveling rail direction by a feed screw, A second elongated hole is formed in a direction intersecting with the first elongated hole in a plan view, and a slide block is provided in which the connection shaft passes vertically through the second elongated hole;
By rotating the feed screw around the axis and moving the slide block, by changing the relative position of the connecting shaft located at the intersection of the first elongated hole and the second elongated hole in the hanging door width direction. The position of the hanging door in the front-rear direction can be adjusted,
For the runner body, a swinging piece that is swingably supported using a horizontal rotation support shaft that supports the roller as a common support shaft is provided, and the swinging piece has a swinging tip at the swinging side end thereof. An upper part of the connecting shaft is supported in a suspended state, and an adjusting screw which is screwed in from the lower surface side of the runner body and whose leading end is in contact with a lower end surface of the rocking piece is provided. The vertical position of the hanging door can be adjusted by adjusting the swinging position of the swinging piece.

In this case, the runner mounting bracket includes an outer case surrounding the slide block housing case and fixing the outer case to the hanging door before mounting the hanging door wheel to the hanging door. In addition, it is desirable that the slide block housing case integrated with the runner body via the connection shaft is inserted into the outer case so that the slide block housing case can be mounted. If an outer case for further housing the slide block housing case is provided, and this outer case is fixed to a hanging door in a factory or the like in advance, the slide block housing case can be easily attached at the work site simply by inserting the slide block housing case into the outer case. Can be performed.

Further, in the runner mounting bracket structure, while an engaging piece is formed in the slide block housing case, a tongue-shaped receiving engaging piece that engages with the engaging piece is formed in the outer case, After inserting the slide block storage case into the outer case, and engaging the engagement piece of the slide block storage case with the reception engagement piece of the outer case, the slide block storage case is located at a position adjacent to the reception engagement piece, It is more preferable that the slide block housing case is fixed to the outer case so that it cannot be removed from the outer case by attaching a cover member having a projection for restraining the displacement of the receiving engagement piece.
