Problems solved by technology

[0005] However, there is a problem in the prior art as described above. It is a structure in which the door hinges are simply fixed to the upper hinge and the lower hinge. The bearing assembly, when installed, ensures the position of the door, or shifts due to the weight of the door during use. Therefore, when the problem of door opening and closing occurs, there is no device that can adjust the height of the door. After the hinges and doors, it is difficult to assemble again etc.

Abstract

The present invention relates to a hinge device for a folding door, which consists of an upper hinge and a lower hinge moving along slide rails arranged on a ceiling and a floor. The upper hinge is configured to make a distance between upper and lower shaft supports maintain an extra space; the lower side shaft support of an upper hinge holder is provided with a spiral hole for connection with a threaded part formed in a hinge shaft; the threaded part has a diameter allowing formation of a clamping edge which is used for placing a shaft joint formed on a hinge leaf and is provided with a wrench groove at the center; when the hinge shaft is operated, the shaft connecting member formed on the hinge leaf placed on the clamping edge to descend and ascend along the hinge shaft. The lower hinge is configured to make the distance between upper and lower shaft supports maintain an extra space; the upper side support of a lower hinge base is provided with a counterbore with an upward opening, which is used for housing a head which is formed at the upper end of a hinge shaft and provided with a wrench groove at the center; the lower shaft support is provided with a counterbore with a downward opening.

Description

technical field [0001] The present invention relates to a hinge device for a folding door, and more specifically provides a hinge device for a folding door. The height adjustment of the upper hinge and the lower hinge is performed by means of a simple tool such as a hexagonal wrench or a screwdriver, thereby providing convenience in setting up the folding door , Moreover, the height of the door can be simply adjusted without separating the door during use, so as to facilitate maintenance. Background technique [0002] Folding door refers to the use of internal and external walls instead of building walls, and it responds to mechanical external forces to ensure durability, and has sound insulation and windproof effects, and is also suitable for external use. In addition, glass can be applied to this product, thereby ensuring visibility, and because of its excellent design, it can be used as an excellent folding door even if it is used as an interior. [0003] The folding doo...
