Description

Folding bed

Technical Field

The utility model relates to the field of sofa beds, in particular to a folding bed.

Background

A folding bed is a foldable and stowable bed, which is generally composed of two parts, one being a bed frame and the other being a mattress. The bedstead is made of metal or wood, can be folded into a compact shape, and is convenient to store and carry. The mattress is composed of springs and sponge, and can provide comfortable sleeping experience. The folding bed is suitable for use in situations where space is limited, such as student dormitories, apartments, hotels, etc. The frame structure of a folding bed is generally divided into three parts: head, tail and bottom. The head and tail are typically comprised of two or more brackets with a cross bar connected therebetween. When the folding bed is needed, only the brackets at the head and the tail are required to be pulled apart, and the cross rod is naturally fixed between the two brackets to form a bed frame. When the bed frame is not needed to be used, the bed frame is only needed to be taken down and folded. It is noted that although the folding bed is convenient, due to its structural specificity, safety issues such as stability and load-bearing capacity of the folding bed need to be addressed during use.

In the related art, the stability and bearing capacity of the folding bed mainly depend on the structural strength of the bed frame structure, and in the bed frame structure, the support legs are main components for supporting weight, and the existing support legs are usually hinged with the bed frame body when in use, and although the support legs can be abutted against the bed frame body, the stability and bearing capacity of the folding bed are still low.
