Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a joining device for connecting a center frame to a vertical stile, which makes it possible to easily and firmly attach a center frame to a vertical stile.

In general, the center stile connecting device for fittings is designed to prevent the mounting screws, etc. that attach the center stile from being exposed to the outside, and also to eliminate the need for machining the joint between the center stile and the vertical stile. A method is adopted in which the center beam is attached to the vertical stile by interposing a connecting block in the middle.
Since the above-mentioned connecting block is temporarily fixed by simply press-fitting it into the hollow part of the middle frame, this temporary fixation becomes unstable, and when inserting it into the vertical stile or screwing the vertical stile and the middle frame together. However, this method has disadvantages in that the connecting block may become misaligned or fall off, or may be inserted more than necessary.
