Description

[Detailed explanation of the invention] [Purpose] Industrial application field...This invention is suitable for display shelves, cupboards,
This invention relates to a mounting device for mounting plate-shaped doors on bookshelves and other cabinets.

BACKGROUND OF THE INVENTION Conventionally, a cabinet door has a glass plate fitted into a frame, and the frame and the edge of the opening of the cabinet are connected by a hinge. Also, plate-like materials consisting only of glass plates without frame frames or only hard synthetic resin plates were used for sliding doors, but were not used for doors. The reason for this is that plate-shaped doors such as glass door plates and hard synthetic resin door plates require screw holes to be drilled when fixing hinges, and the supporting area is small, making it difficult to use screws to support opening and closing. If force is applied to the mounting part, cracks, cracks, chips, etc. will occur, which will not only make the door plate fragile, but also expose the hinge part to the outside, and when the door is opened, the edge of the door on the hinge side will fall into the opening of the cabinet. The disadvantage was that it entered the interior of the opening and narrowed a portion of the opening.

Problems that the invention aims to solve: This invention allows plate-shaped doors such as glass doors to be opened and closed, and can be installed firmly and stably on the side panel of the cabinet without applying distortion, and when the plate-shaped door is opened. The opening of the cabinet is completely open, so there is no problem in getting items in and out, and when the plate-shaped door is closed, the entire front side of the side plate can be closed with a rod-shaped shaft frame for a good appearance. The object of the present invention is to provide a plate-shaped door mounting device mainly used for wooden cabinets.
