Abstract

The present invention relates to a folding door. The folding door includes: a door frame formed in the shape of a square frame; multiple doors installed in the door frame in a folding type; and a hinge unit installed between the door frame and the door and doors. The hinge unit comprises: a first hinge member fixed to a first door; a second hinge member fixed to a second door; a hinge shaft connecting the first hinge member and the second hinge member to rotate with each other; a first nut member inserted into a hanging groove formed in the first door and coupled to the first hinge member by a bolt; and a second nut member inserted into the hanging groove formed in the second door and coupled to the second hinge member by the bolt. The folding door can prevent the door and the door frame from being damaged as a bolt hole is not formed on the door and the door frame. The folding door also can be easily and conveniently reassembled after the door is separated as only the first nut member and the second nut member are unwound when the door is separated. Also, the height of the folding door can be conveniently readjusted.

Description

FOLDING DOOR

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a folding door which is easy and convenient to separate and reassemble a door and is easy to assemble a door frame.

Generally, a folding door can be opened to more than 95% because two or more doors are opened or closed by folding, and the door can be used as an indoor partition.

A conventional folding door can be folded by a plurality of hinges to open and close a ceiling, a floor, a doorway surrounded by the first side and the second side, as disclosed in Patent Registration No. 10-1056382 (Aug. 05, 2011) A plurality of doors having an upper end, a lower end, a first side end and a second side end, a first position closed to be aligned with a first direction in which the plurality of doors are closed, A first guide frame installed on the ceiling for guiding a direction change of a first door among the plurality of doors that move between a first position and a second position opened in a second direction of the first door, A first sliding roller mounted to roll and slide along the first guide frame and a second sliding roller mounted on the floor for guiding the direction change of the first door, A second guide frame having a first rail aligned with the first direction and a second rail extending from the rear end of the first rail in the second direction, And a second sliding roller mounted on the lower end of the second door, and adjacent two door openings among the plurality of door openings are interconnected by a plurality of multi-axle hinges.

Since the conventional folding door is fastened by fastening the multi-axle hinges to the doors, the holes through which the bolts are drilled in the door or the door frame remain. Therefore, when the doors are re-assembled again, There is a problem that the fixing force is lowered because the hole is loosened.

In addition, the conventional folding door has a problem in that the guide frames are deformed due to external impact when the guide frames of the door frame are assembled by fixing the corner portions of the guide frames by bolts after the corner portions are brought into contact with each other .
