Abstract
A convertible furniture frame assembly having a stationary base assembly that supports at least one retractable supporting means. This supporting means is used to support retractable furniture components as they are raised and lowered. The invention further incorporates at least one generally horizontal self standing support means to stabilize the furniture frame assembly and at least one two-bar torsion system that aids users in raising and lowering the furniture components. The user is also aided by a self-energizing latching means that automatically latches the retractable supporting means in its lowered position. The user is further convenienced by a retaining means that prevents loose articles on the furniture components from sliding into the base assembly during retraction.
