The present invention relates to a lower pivot positioner capable of simply fixing and positioning a lower pivot bracket of a floor hinge.

In forming the wall structure using tempered glass, a window frame is used, and a window frame can fix a single or double glass. If one glass is used, insulation and soundproofing performance deteriorates compared to the case of using a double glass. Therefore, a double glass such as a pair glass is mostly used in a window installed in an entrance such as a government office, a school, a hospital, .

However, even if a double glass is used, the conventional window frames directly contact outdoor and indoor air, so that it directly transmits outdoor temperature. Since a conventional window frame uses a stainless steel frame cover for an aluminum core, It can cause condensation due to temperature difference between inside and outside due to high temperature, and it can be a cause of heat loss.

Further, a tempered glass door is mainly installed in a window frame, and a floor hinge is mainly used for fixing the tempered glass door. The floor hinge includes a lower hinge body that operates by hydraulic pressure, a lower pivot plate that connects the lower hinge body and the lower portion of the door, an upper hinge bracket mounted on the upper portion of the door corresponding to the lower hinge, As shown in FIG.
