Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an adjusting structure capable of adjusting the vertical height of a sliding door.

[0002]

2. Description of the Related Art Conventionally, as shown in the perspective view of FIG. 7, a sliding door 1 is provided with a pair of vertical edge frames 2 and 2 on its outer periphery in parallel with the vertical direction. An upper cross frame 3 is framed at the upper end of 2, and a lower cross frame 4 is framed at the lower end of the pair of vertical edge frames 2 and 2. However, it was difficult to work because it required the skill of a craftsman to shave and adjust it on site. As a remedy for this, as shown in the perspective view of the main part in FIG. A driving nut 51 formed by projecting 51a, 51a is driven into the driving nut 51.
There is a structure in which the height of the sliding door 1 can be adjusted by appropriately adjusting the protruding height of the adjusting bolt 52 by screwing the adjusting bolt 52 onto the driving nut 52 by screwing the adjusting bolt 52 into and out of the driving nut 51. As shown in FIG. 9, the driving nut 51 and the adjusting bolt 52 are embedded in the bottom surface of each of the pair of vertical edge frames 2 and 2.

In such a conventional structure, the vertical frame 2
When the driving nut 51 is driven into the prepared hole 5 and fixed, the vertical edge frame 2 often cracks and becomes a defective product. Also, such a sliding door 1 is set in the sill groove of the sill. When fitted and moved along the sill groove, the adjustment bolt 5 is moved by frictional resistance between the sill groove and the adjustment bolt 52.
However, there is a problem in that the height adjustment of the sliding door 1 becomes unstable because 2 rotates about the driving nut 51.
