Description

Technology Field

[0001] The present invention relates to a door structure, and more particularly to a door structure having a bending prevention structure that solves the problem of bending occurring in high-height doors. Background Technology

[0002] Due to the demand for various interiors, such as the installation of hidden doors, there is a growing need to manufacture interior doors with a height exceeding the 2,400mm limit, which was previously restricted by the standard apartment ceiling height of 2,500mm.

[0003] A hidden door refers to a door that is perfectly integrated with surrounding walls or furniture to conceal its presence and create a visually sleek and clean interior. Bending refers to the phenomenon where a door deforms or warps. Bending is mainly caused by changes in temperature, humidity, or load, and can lead to a decrease in the door's functionality and damage to its appearance.

[0004] Due to the increase in the height of such interior doors, if a conventional door structure of standard height is adopted, the occurrence of bending in the door is inevitably accelerated, damaging the interior such as hidden doors, and consequently, the door needs to be replaced, which shortens the lifespan of the door.

[0005] Therefore, there is an urgent need to develop a door frame structure with a new anti-bending structure for high-height doors. The problem to be solved

[0006] Therefore, the present invention aims to provide a door structure having a new anti-bending structure for high-height doors. means of solving the problem

[0007] To achieve the above objective, the present invention relates to a door structure having a bending prevention structure comprising side panels (10) constituting both sides of the door and a support structure formed by being coupled to both sides of the inner surface of the side panels to support the side panels and maintain the spacing of the side panels, wherein the support structure comprises one or more support reinforcing members, and one or more of the support reinforcing members are characterized in that a part or all thereof is made of a molded metal material.

[0008] Preferably, one or more of the above-mentioned support reinforcing members are made of a molded synthetic resin material, in part or in whole.

[0009] Preferably, the support reinforcing member comprises a first support reinforcing member (20) coupled to the inner surface of the side panel, a second support reinforcing member (30) coupled to the outer side of the first support reinforcing member (20), and a third support reinforcing member (40) coupled to the outer side of the second support reinforcing member (30).

[0010] Here, a step and a coupling groove are formed on the outer side of the third support reinforcing member (40), and it is preferable to include a finishing reinforcing member (50) that is coupled to the coupling groove and finishes both sides of the door, in a shape that adheres to the step.

[0011] In addition, the finishing reinforcement member (50) is preferably a molded metal plate.

[0012] Furthermore, here, the finishing reinforcement member (50) is preferably a molded aluminum plate.

[0013] Additionally, preferably, one or more of the second support reinforcing member (30) or the third support reinforcing member (40) are bar-shaped made of extruded aluminum material.

[0014] In addition, preferably, one or more of the second support reinforcing member (30) or the third support reinforcing member (40) are formed by inserting a metal reinforcing structure into an extruded synthetic resin bar.

[0015] Here, the metal reinforcing structure is preferably a steel member with a horizontal cross-section formed into an L-shape or a T-shape.

[0016] In addition, the metal reinforcing structure is preferably made of aluminum material with one or more insertion holes formed in a horizontal cross-section in the shape of an "L," and a steel reinforcing member with a horizontal cross-section formed in the shape of an "L" is inserted into the insertion holes. Effects of the invention

[0017] According to the present invention, a door structure having a new structure of a bending prevention structure that improves upon a conventional door structure can be provided.

[0018] In addition, according to one embodiment of the present invention, one or more of the support reinforcing members have a bending prevention structure in which part or all thereof is made of molded metal material. This has the effect of solving the problem where, when adopting a conventional door structure of normal height due to an increase in the height of the indoor door, the occurrence of bending in the door is inevitably accelerated, damaging the interior of the hidden door, and consequently requiring replacement of the door, thereby shortening the lifespan of the door.

[0019] In addition, through an embodiment of a bending prevention structure made of metal material that can be changed in various ways, it is possible to provide a door structure and a door that have a bending prevention structure optimized for the installation and usage environment of each door, or the size, structure or shape, material, and manufacturing process of the door.
