Foldable bed framework structure

Abstract

A foldable bed framework structure includes two longitudinal rods, three transverse rods and a plurality of leg stands. Pivot holes are respectively defined on each of the longitudinal rods, and joint holes corresponding to the pivot holes are respectively defined on each of the transverse rods. Each of the transverse rods further has axial holes formed on at least two end portions thereof and passing through side walls thereof. The leg stands are disposed correspondingly to the axial holes. Each of the leg stands is defined as a U-shaped rod with an opening open on one side. Two ear plates with respective pivot apertures are formed on a top of each leg stand. The two ear plates are pivotally connected to the axial holes of the transverse rods. This foldable bed framework structure can be folded into a minimum size to facilitate the packing and the transportation thereof.

Description

BACKGROUND OF THE INVENTION[0001](a) Technical Field of the Invention[0002]This invention relates to a bed framework and relates particularly to a foldable bed framework structure.[0003](b) Description of the Prior Art[0004]As illustrated in FIGS. 1-2, a typical foldable bed framework comprises two pairs of longitudinal beams 10, three pairs of transverse beams 20 and a plurality of leg stands 30. Each pair of longitudinal beams 10 has two longitudinal rods 101 pivotally connected to each other by using a U-shaped pivotal part 40. U-shaped pivot units 50 are respectively disposed on a lateral inner side of the two longitudinal rods 101 of the two pairs of longitudinal beams 10. Openings of the two pairs of pivot units 50 are oppositely disposed. The leg stands 30, located on an inner side of each of the pivot units 50, are unidirectionally and pivotally connected to a lower part of each of the longitudinal rods 101 by using a first pivotal unit 60. Each pair of transverse beams 20 h...

AI Technical Summary

Benefits of technology

The invention is a foldable bed framework with a simple structure that can be easily packed and transported. It has a smaller folded volume compared to typical frameworks, making it more convenient for packing and transportation. The reduced number of rod components saves time and effort and reduces the use of rod joint accessories, resulting in a lower cost. The use of leg stands to hold the transverse rods directly also contributes to a smaller folded volume.

Problems solved by technology

The foldable bed framework may fold the components into a dense configuration, and such folded configuration can occupy less space and increase the transporting quantity of the bed framework.

Firstly, the foldable bed framework has numerous rods and needs many processes for folding and unfolding. Hence, the assembling operation of the bed framework takes lots of time and effort.

Secondly, the structure becomes more complicated as the foldable bed framework contains numerous joint components. The foldable bed framework comprises two pivotal parts 40 for connecting the longitudinal rods 101, two second pivotal units 70 for connecting the transverse rods 201, four pivot units 50 for connecting the longitudinal rods 101 to the transverse rods 201, and a plurality of first pivotal units 60 pivotally connected to the leg stands 30. As the abovementioned components have different structures and need to be individually molded and formed for production, the cost of the production is higher, and the cost of the whole bed framework is also increased. Additionally, the numerous joint components may incur the situation of missing the components easily.

Third, each leg stand 30 abuts against the longitudinal rod 101 or the transverse rod 201 after the leg stand is folded, so a gap defined by a width of two leg stands 30 is left between the two transverse rods 201 or the two longitudinal rods 101 after the rods are all folded. Thus, the bed framework cannot be folded to a minimum size.
