Description

Curved bed head and device and method for manufacturing the same {CURVED BED HEAD AND APPARATUS AND METHOD FOR MANUFACTURING THE SAME}

The disclosed content relates to a curved bed head and an apparatus and method for manufacturing the same.

Unless otherwise indicated herein, the matters described in this identification are not prior art to the claims of this application, and are not admitted to be prior art by being described in this identification.

In general, a bed is a piece of furniture that allows the user to lie down and rest or sleep. Depending on the size, it is classified into a double bed or a single bed, and according to the type, it is classified into a single bed or a bunk bed. These bed frames are made of various materials such as wood, metal, and synthetic resin. Frames made of these materials are assembled, a support plate is built into the inside of the frame, and a mattress with cushioning power is laminated on the top of the support plate.

This type of bed frame is generally used by installing a headboard at the head and a footboard at the feet, and combining the side boards so that they are at right angles to the headboard and footboard. Most bed frames are formed by extending the headboard and footboard to form legs, or by forming legs at the bottom of the headboard and footboard to support the bed.

In addition, in order to combine the side boards so that they are perpendicular to the headboard and footboard, a bracket is used and fixed with screws on the inside of each board. This means that the screw position of each board must be accurately fixed to ensure that each board is horizontal and vertically connected. Therefore, it is difficult to adjust the verticality and height of each board at once, making it difficult to assemble by drilling several screw holes in each board.

Therefore, in the case of wood or synthetic resin, if the screw holes are drilled multiple times, the lifespan of the product is reduced and the height of the bed cannot be adjusted depending on the bed arrangement.

In addition, the process for rounding both corners of the bed head, which is generally made of plywood, takes a lot of time and money, making it uneconomical.
