Abstract
A multi-functional table of adjustable height has concealed supplementary legs capable of being swung downwardly to effectively extend the lengths of the four main legs of the table. The supplementary legs are concealed within housings that extend between the lower extremities of adjacent main legs. A release mechanism, operable from above the housings, controls the release of the supplementary legs. The deployed supplementary legs are secured by an upward sliding motion.
Claims5
A multi-functional table of adjustable height comprising:
- (a) a flat top panel having upper and lower surfaces and adapted to be horizontally disposed,
- (b) four straight main legs extending vertically downwardly from said top panel in a rectangular locus, said main legs being in fixed engagement with said top panel, and having lower extremities disposed in a horizontal plane,
- (c) paired straight hollow housings in opposed parallel relationship, each housing extending between the lower extremities of two opposed contiguous main legs, said housings having open bottom portions, and end portions adjacent each main leg,
- (d) two straight supplementary legs stored within each housing, each supplementary leg having a proximal extremity pivotably secured to the housing adjacent the lower extremity of a main leg, and a distal extremity adapted to swing downwardly into a deployed mode in vertical alignment with an associated main leg,
- (e) holding means located within the end portions of each housing for securing each supplementary leg in its deployed mode, and
- (f) retaining means associated with each housing for preventing inadvertent deployment of the supplementary legs.
