Description

[Detailed Description of the Invention] The present invention relates to a metal lower frame for indoor fittings that allows the width between the cores of a plurality of running rails for fittings to be varied as desired.

Traditionally, wooden sills have been used as the lower frame for interior fittings used for doorways and windows in Japanese-style rooms, but wooden sills are made of one or more strips that guide the fittings around horizontal timbers of a predetermined size. Since it has grooves and ridges, or one or more running rails for fittings are attached to the upper surface of the horizontal timbers, the space between the centers of the grooves or the center of the running rail for fittings is The dimensions between the cores were constant, and it was not possible to change the width to the desired dimension, so there were differences in the size of Japanese-style fittings, such as those for Kanto and Kansai.
If the width of the side part of the fittings that fits into the horizontal stile is different, or if the dimensions of the stile of the fittings are different, the width of the side part can be adjusted by planeing the Japanese-style fittings at the construction site. Or, because the fittings are made with a stile size that fits between the cores of the running rail for the fittings, it is very time-consuming to install the fittings, and it is also necessary to prepare several types of fittings with different stile sizes, so it is difficult to fit between the fittings. 〓Skilled joiners were required to carry out smooth and light construction without any wobbling or wobbling. In addition, recently, a flat metal lower frame with multiple running rails for fittings protruding from the top surface has been developed and used, but this type of frame allows the width between the cores of the running rails for fittings to be varied as desired. Therefore, it was necessary to manufacture and prepare many types with different core widths, which was extremely inconvenient in terms of manufacturing and construction.

The present invention relates to the structure of a metal lower frame for indoor fittings, which aims to eliminate the above-mentioned conventional drawbacks with a simple structure.One example of the structure is explained below with reference to drawings. be.
