Description

Door

The present invention relates to a door, and more particularly, to a door that is integrally closed with the front and rear sides of the door by bending or lapping the inner material surrounding the frame forming the door with the side curling surface.

As is well known, a building structure such as a door is composed of an inner frame forming an interior and an interior material surrounding the inner frame to form an outer shape.

The interior material used in the conventional door is mainly manufactured by bonding a finishing material, such as PVC (Polyvinyl CHLORIDE) sheet, veneer or paper printing paper with an adhesive material on the wood plate layer.

Therefore, in the case of a door used in a place where a lot of water is used, such as a bathroom or a balcony, it lacks waterproofness and is separated from the adhesive layer while being lifted, thereby reducing durability.

In addition, in the case of the door used in the prior art, because the round processing for bending is impossible, the front and rear of the door together with side flanks can not be integrally covered with the disadvantage of finishing.

Therefore, as the side edges of the doors are attached with a separate PVC sheet, veneer veneer, paper printing and synthetic resin edges, and aluminum at low pressure using a thermoplastic adhesive, the durability of the front side and the side and side edges are reduced. There is a disadvantage in that it does not match with each other to reduce the aesthetics.

Furthermore, additional members such as PVC sheets, veneer veneers, paper printing and synthetic edges, aluminum, etc. are used to finish the side flanks of the doors, resulting in increased manufacturing costs and lower productivity in their attachment process. Has disadvantages.

An object of the present invention for solving the above problems, by using a bending or wrapping method to wrap the inner frame forming the door shape to allow the front and rear of the door to be integrally finished with the side curling surface unit manufacturing cost It provides a door to lower and increase productivity.
