The bidirectional hinged door comprises: a first magnet member mounted in a sliding route of a guide rail to be fixed; a slide moving plate seated on the guide rail to move along the sliding route and having a second magnet member disposed on a side facing the first magnet member to provide a fundamental force to the first magnet member; and a safety guide bar, of which one side is hinged to an upper doorframe to be rotated axially and the other side opposite to the first magnet member is combined with the slide moving plate, wherein the safety guide bar moves the slide moving plate in the direction that the first magnet member is mounted so that the slide moving plate comes into contact with the first magnet member when the door leaf is rotated toward the door frame to be closed. According to the present invention, the bidirectional hinged door can stably maintain a closed state in place by a magnetic force of the door leaf when the door leaf is rotated to get closer to the door frame.

Description

HINGED DOOR HAVING FRONT AND BACK OPENING OPERATION "

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a hinged door which is opened in both forward and rearward directions and which is stably closed in a forward and backward direction without staggering. More specifically, when the hinged door is opened to the front or rear, To a fixed position so as to be stably closed without any back and forth shaking.

Generally, a door is installed for the purpose of entering and exiting the exterior wall of a building, and is formed of transparent or opaque glass or iron, and a door frame is formed along the outer peripheral surface thereof to form a structure capable of opening and closing the door from the door frame do.

These doors are variously classified according to the opening and closing method. They are used in an office or a front door, and are hinged doors that are opened and closed as the doors coupled by the hinges are rotated vertically with respect to the door frame, and are used in homes and restaurants. There is a sliding door which is opened and closed according to parallel movement.

The hinged door has a structure in which the upper rod and the lower rod are installed at the upper end and the lower end of the one end portion of the fixed door frame, respectively, and the hinged door and the door frame are hinged to each other so as to rotate to both the inside and outside sides around the hinge axis .

In addition, since the hinged door must be able to pivot freely between the inside and the outside, it can not be installed between the door frame and the side frame of the hinged door completely, and the hinged door is closed (Gap) between the door frame and the side of the hinged door in order to prevent safety accidents such as the fingers of the passengers (especially children).

Therefore, the gap (gap) serves as a passage of the wind, so that the cooling efficiency of the cooling owing to decrease, the energy consumption is inevitably increased, and the pollutants such as external noise and dust are transmitted to the inside, So that the user is exposed to such a problem and suffered many problems.

Korean Patent Publication No. 10-1695658 (published on Feb. 1, 2013) Korean Patent Publication No. 10-1536647 (published on Jul. 15, 2015) Korean Patent Publication No. 10-2013-0091433 (published on Aug. 31, 2013) Korean Utility Model Registration No. 20-0325942 (Announced on September 10, 2003)

Therefore, the object of the present invention is to adjust the rotation of the door so that the position of the door can be adjusted to the correct position by using the magnetic force acting inside itself when the door of the door opened to the front or rear is rotated to the adjacent position of the door frame To provide a two-way hinged door.

In order to accomplish the object of the present invention, in an embodiment of the present invention, a door which is hinged to an upper door frame or a lower door frame or both of them, a guide rail provided at an upper end of the door, And a closed position adjusting device installed on the guide rail, wherein the closed position adjusting device comprises: a first magnet member fixed to a slide path of the guide rail; And a second magnet member which is seated on the side opposite to the first magnet member and moves along the slide movement path to provide a force to the first magnet member, And the other side thereof is coupled to the slide moving plate, and the door is hinged to the upper door frame And a safety guide bar for moving the slide moving plate in a direction in which the first magnet member is installed so that the slide moving plate can be brought into contact with the first magnet member when the sliding guide plate is rotated toward the door frame so as to be closed. Provide a two-way hinged door.

According to the present invention, when the door is rotated so that the door is closer to the door frame, the door can be stably maintained in a closed state at the door by its own magnetic force. Further, since the present invention utilizes the magnetic force acting inside the door, no additional construction is required for the door frame.

Further, although the closed state is maintained with respect to a natural external force such as a draft or the like, the closed state of the artificial external force due to the act of pushing or pulling the door of the closed state by the elderly person is easily canceled. In other words, according to the present invention, since the door can be opened and closed by pushing any part of the door without holding a separate handle, the elderly person can open and close the door using any part of the body while holding the object in his or her hand. Convenience is increased.

In addition, since the present invention does not require a locking device for maintaining the closed state unlike the prior art, it is possible not only to provide simple aesthetics but also to reduce the manufacturing cost.
