ABSTRACT:
A frame structure for furniture, especially table frame structure, according to which a first rigid support structure supports a pivotal support structure which is pivotally connected to the first rigid support structure for selective movement along a vertical plane from a first position of use in which it forms an upwardly directed extension of the first rigid support structure to a second position of use in which the pivotal support structure is folded downwardly at least approximately onto the first rigid support structure. The frame structure furthermore comprises a second rigid support structure which is pivotally supported by and extends upwardly from the pivotal support structure while forming with the latter a parallelogram linkage system, the pivotal support structure being adapted selectively to be locked to the second rigid support structure in the first position of use of the pivotal support structure.
