Description

Folding door in the form of an ultra-slim frame}

The present invention relates to a folding door in the form of an ultra-slim frame, and more specifically, to a folding door in the form of an ultra-slim frame in which the length of the vertical bar is drastically reduced and the design can be changed to have a custom design in the direction desired by the consumer. will be.

In general, a folding door literally refers to a folding door. It can be used as a replacement for the interior and exterior walls of a building wall, and its durability is guaranteed in response to mechanical external forces. It is also suitable for exterior use as it has soundproofing and windproofing effects. . In addition, by applying glass to the product, visibility can be secured, and the design is excellent, so it is also used for internal purposes.

In addition, in order to make valuable use of space, folding doors open more than 90% of the 50% opening structure of existing doors, creating a spacious living space for residential use and facilitating customer accessibility for commercial use, mainly used in high-end restaurants, apartments, and restaurants. It is being used for entrances or split doors of houses, commercial buildings, etc.

These folding doors are designed so that the entrance can be completely opened in places where there is no space to completely open the door outside the entrance of the wall. The door frame is constructed according to the shape of the entrance, and a plurality of sliding doors are attached to the hinge so that they can rotate around each other. and one end of the sliding door is connected to rotate on one side of the door frame.

Conventional folding doors have a problem in that since a door frame and a plurality of doors are connected to each other by a hinge, gaps are created between the door frame and the door and between the plurality of doors, which reduces the soundproofing effect and windproof effect.

Meanwhile, the above-mentioned background technology is technical information that the inventor possessed for deriving the present invention or acquired in the process of deriving the present invention, and cannot necessarily be said to be known technology disclosed to the general public before filing the application for the present invention. .
