The invention relates to a novel sofa bed iron stand mechanism. According to the novel sofa bed iron stand mechanism, bed frames are sequentially hinged, front foot assemblies are hinged to the two sides of a first frame body, middle foot assemblies are hinged to the joints of the two sides of the first frame body and the two sides of a second frame body, first connecting rods are hinged between the front foot assemblies and the middle foot assemblies, and mounting plate assemblies are connected to the two sides of the second frame body; second connecting rods are hinged between the middle foot assemblies and the mounting plate assemblies, the two sides of the backrest are connected with rear supporting plate assemblies respectively, each rear supporting plate assembly is connected with one end of a third connecting rod, the other end of each third connecting rod is connected with an L-shaped connecting piece on the lower portion of the third frame, and a first supporting rod and a second supporting rod are sequentially hinged between each rear supporting plate assembly and the corresponding L-shaped connecting piece; a locking spring is arranged between the first supporting rod and the second supporting rod. According to the invention, the function of mutual conversion between the sofa and the bed is achieved through stretching and folding of the two associated bed frames and the rotatable backrest.
Description
technical field [0001] The invention relates to a sofa bed, in particular to a novel sofa bed iron frame mechanism. Background technique [0002] Emphasis on storage and comfort in the modern living environment. In some densely populated cities and countries, storage and organization are not limited to daily utensils. Moreover, because some living environments are not very abundant now, the living area is very compact. As a result, people usually arrange their living environment better in a limited space. And bed is one of people's requisite housewares in the home life. However, beds typically have a relatively large footprint, often occupying a considerable amount of living space. [0003] In order to improve the reasonable usable area, people obtain more space for activities by improving the use of the bed. Therefore, the sofa bed was born. The sofa bed allows people to obtain a larger space for living activities through the mutual conversion between the sofa and the...
