Abstract
A convertible furniture frame assembly (8) having a stationary base assembly (12) that supports at least one retractable supporting means (14, 16). This supporting means (14, 16) is used to support retractable furniture components (10a, 10b) as they are raised and lowered. The invention further incorporates at least one generally horizontal self standing support means (18) to stabilize the furniture frame assembly (8) and at least one torsion system (20, 20') that aids users in raising and lowering the furniture components (10a, 10b). The user is also aided by a self-energizing latching means (28) that automatically latches the retractable supporting means (14, 16) in its lowered position. The user is further convenienced by a retaining means that prevents loose articles on the furniture components (10a, 10b) from sliding into the base assembly (12) during retraction.
