发明名称 Portable desk with bifolding supports
摘要 A portable desk with a work surface panel supported between two support compartments which are hinged. Each support compartment not only is foldable from a right angle position of support to a parallel storage folded inward and beneath the work surface panel, but also is foldable from the right angle support position outward and parallel to the work surface panel. An interposed hingeable piece allows the combined support compartments and panel to bifold outward and bridge the space between two surfaces such as the arms of an armchair or bedrails.
