Description

[0001] The present invention relates to a side frame structure of a swing door,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a swing door and a swing door side door frame, and more particularly, to a swing door having a swing door, The present invention relates to a structure of a swing door and a swing door side door frame that can maintain airtightness between a side surface of a door and a side door frame.

Generally, doors and doors of shops, offices, theaters, hotels, department stores and the like are made of tempered glass, metal or nonmetal, and swing doors, which are openable and closable doors both inside and outside, are widely used. The swing door is structured such that the swing door and the door frame are hinged to each other, and the swing door is pivoted to both the inside and the outside sides around the hinge axis, with the upper rod and the lower rod installed at the upper and lower ends of the one-

Conventionally, there have been many cases where a swing door is installed by mounting a frame only on the upper and lower portions of the tempered glass. However, swing doors provided with a frame on all four sides of the door edge are gradually installed. However, since the swing door which can be opened to both the inner side and the outer side must be able to freely pivot inward and outward, it is impossible to install the swing door completely between the door frame and the side frame of the swing door, Therefore, when the swing door is closed, there is a gap (clearance) between the door frame and the side surface of the swing door in order to prevent a safety accident such as a finger of a passenger (especially a child) being caught.

In addition, since the frame of the swing door has a certain thickness, when the swing door is pivoted inward and outward, the corner portion of the swing door side frame should be spaced considerably in order to rotate smoothly without colliding with the side door frame. Therefore, the gap (gap) serves as a passage of wind, and the efficiency of cooling and heating is low, so that the energy consumption is inevitably increased. The pollutants such as external noise and dust are transmitted to the inside, So that there are many problems such as being damaged.

In order to solve such a problem, a sponge or a wind-resistant paper is attached along the edge of the swing door. However, since the swing door is inconvenient to use and the air curtain is replaced with an air curtain, It is a reality that the power consumption is greatly increased while not solving many problems completely. In order to solve the above problems, the present applicant has developed a patent registration No. 1122546 "Airtight device for a door of a hinged door" after a lot of efforts. The patent discloses a hinged door frame, (Gap) between the doors.

However, when the above-mentioned patent is actually applied and used, a problem that has not been considered yet occurs. First, a door frame made of a metal member is fixedly installed, and one side of the door frame is hinged Since the frame of the swing door is made of metal and the door frame and the swing door frame do not have a heat insulating member between the inside and the outside, thermal conduction occurs through the door frame and the swing door frame, thereby causing a considerable heat loss.

Second, in order to smoothly swing the swing door, it is necessary to install the shock absorbing hollow rubber body on both sides of the swing door and the side door frame after installing the swing door between the side frame and the side frame. Since the shape of the hollow rubber body is distorted as the door rotates, the shape is deformed over time and the aesthetic appearance is bad. When the shape is deformed, the tip of the mohair does not contact with the side door frame. When the swing door is closed, There is a gap between the door and the side door frame.

In order to solve the above problems, the present applicant has developed and applied a patent application No. 2013-168664 entitled " Device for sealing and sealing a hinged door ", which solves the problems occurring in the upper and lower portions of the swing door, The problem still remains to be solved, and the present invention aims to solve the side problem of the swing door.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a swing door in which all four edges of a door are formed as a frame, regardless of the thickness of the swing door side frame, And to provide a structure of a swing door and a swing door side door frame which can reliably maintain the airtightness between the side door and the side door of the swing door when the swing door is closed while the door is smoothly rotated.

In order to solve the above-mentioned problems, the swing door and the swing door side door frame according to the present invention are applied to a swing door capable of opening and closing both inside and outside directions and a door frame fixed to install the swing door. The structure of the door and side door of the swing door includes a recess formed in a central portion along the height direction of the left door frame and the right door frame, respectively, and the left and right frames of the swing door Respectively, so that when the swing door is closed, the space between the side surface of the swing door and the side door frame is sealed.

Preferably, gaskets having an inwardly rounded portion are inserted into the groove formed in the left door frame and the right door frame, respectively, and mounting gaskets are mounted on the side surfaces of the left frame and the right frame of the swing door, Moeheya is mounted, or Moeheya is integrated with the mounting gasket.

Preferably, the left frame and the right frame and the left frame and the right frame of the swing door are divided into inside and outside, respectively, and a heat insulating material is inserted and assembled between the separated frames.

The swing door and the swing door side door frame according to the present invention having the above features are characterized in that the side door frame is not a flat plate shape in a door frame in which a swing door made of a frame of all four sides of the door is mounted, Even if the swinging door is provided close to the side frame and the side frame of the swinging door, regardless of the thickness of the swinging door side frame, when the swinging door is rotated, (Or gasket) attached to the side of the swing door ensures that the airtightness between the side frame of the swing door and the side door frame can be maintained even when the swing door is closed. have.

In addition, since the door frame and the swing door frame are separated into the indoor side and the outdoor side and the heat insulating material is inserted in the middle, it is possible to prevent the heat loss from escaping through the door frame and the swing door frame, , It is possible to maintain the airtightness by preventing the gap between the side door frame and the swing door and to prevent the wind from being ventilated. Therefore, the heat loss through the gap is blocked to improve the heat insulation effect and the cooling / heating efficiency Energy consumption can be reduced, and pollution such as external noise and fine dust can be prevented from flowing into the room through the gap.
