Convertible furniture

Abstract

The invention relates to furniture (2) capable of being converted between chair and desk. The furniture is provided with two plates (4 and 6) which are hinged together and can move as follows: chair construction is shown, wherein one plate (4) is served as a seat and the other plate (6) is served as the back of chair, and desk construction is shown, wherein the plate forms the top of desk. A movable supporting part (14) is at the stacking position below the plate (4) in the chair construction and is rotatable with the hoisting position, at the hoisting position, the movable supporting part (14) provides support to the lower side of the plate (4) and support to a hinge (5). Preferable implementation comprises a spring loading pin fixed on one plate, and the spring loading pin is jointed with the supporting part to lock component into each one in construction thereof.

Description

technical field [0001] The present invention relates to an article of furniture that can be converted from a chair to a table. The table can function as a regular table top, but is particularly suitable for use as an ironing board or as a table for changing a baby's diaper or clothes. Background technique [0002] It is known to build a chair that converts into an ironing table. Examples of these are described in US Patents 5,507,549 and 5,833,306 and Australian Patent 686519. While the structures described in the above-referenced prior art may be suitable for small quantities of hand-built and sold, they cannot be used for mass production or low cost because of their size, complexity and / or inability to be broken down for flat pack shipment. cost shipping. [0003] The difficulty with the previously described structures is that unless manufacturing tolerances are kept tight, the means of locking the unit into its various configurations may result in a structure that, in ...

Problems solved by technology

While the structures described in the above-referenced prior art may be suitable for small quantities of hand-built and sold, they cannot be used for mass production or low cost because of their size, complexity and / or inability to be broken down for flat pack shipment. cost transportation

[0003] The difficulty with the previously described structures is that unless manufacturing tolerances are kept tight, the means of locking the unit into its various configurations may result in a structure that, in the table configuration, rigidly holds the elements of the table top in a coplanar configuration medium without significant movement in hinges engaging planar elements

Another difficulty with the previously described construction is that some of the movable parts of the unit can be accidentally moved during use, making the unit potentially unstable under certain conditions
