Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support for a door panel such as a pivot runner for a folding door, a pivot shaft unit, a latch body, or a runner for a sliding door of furniture.

[0002]

2. Description of the Related Art In a support for a door panel of this type,
There is a case in which a plastic-molded tubular case is driven into a door panel and fixed, a runner shaft and a pivot shaft are supported by the case so that the runner shaft and the pivot shaft can be retracted, and a spring incorporated in the case urges the shaft body to advance. The latch unit disclosed in Japanese Utility Model Publication No. 6-28153 and the pivot shaft unit disclosed in Japanese Utility Model Publication No. 5-6369 are examples thereof.

FIG. 7 shows a conventional pivot runner. There, a case 41 is formed by a pair of left and right half-cylindrical half cylinders 40, 40. The semi-cylindrical bodies 40 and 40 are hinge portions 42.
It is connected through and is molded by plastic at the same time. A spring 43 and a runner shaft 44 are provided in the case 41.
After assembling, the half cylinders 40, 40 are joined together in a lid-matching manner, and the fixing ring 45 is externally fitted to the half cylinders 40, 40 to maintain the joined state. The joining surfaces of the half cylinders 40, 40 are provided with a projection 46 and a recess 47 which are fitted and engaged with each other, so that the lid fitting and joining state can be temporarily held. A convex roller 48 is mounted on the upper part of the runner shaft 44, and the roller 48 is rotatable via a washer 49 mounted on the shaft upper part and a group of small steel balls 50 supported by the washer 49. It is pivotally supported. Reference numeral 51 is a flange.

[0004]

The above-mentioned pivot runner has the case 41 and the runner shaft 4 except for the roller 48.
4, the spring 43, and the fixing ring 45 are included in the four parts, and it is not possible to omit any of the four parts in order to maintain the shaft support function. At the time of assembly, a process of temporarily assembling the runner shaft 44 and the spring 43 to join the half cylinders 40, 40 and a fixing ring 45 is driven into the cylinder shaft using a jig to make the half cylinders 40, 40 inseparable. The process of fixing is indispensable.

An object of the present invention is to improve the joining and fixing structure of the half cylinders so that the number of parts and the number of assembling steps can be reduced, and a supporting tool for a door panel which is cheaper than the conventional example is provided. It is in. Another object of the present invention is to provide a support for a door panel that can fix both cylinders inseparably by simply joining and operating a pair of half cylinders and that can be easily assembled without using a jig. To provide.
