  • Sofa table is also used to place food and beverages either while watching television or receiving guests, it is known that conventional sofa table usually has a top at the same level as the sofa, therefore it is necessary to bend over to reach the dish, it is not only clumsy and not ergonomic but could also be a difficult task for people with physical limitations to reach a level so much lower than that to which one is used to.
  • a sofa table includes a horizontal table top supported by plurality of side support members or leg means at each end of said horizontal table top, at least a portion or the whole of the table top being a height adjustable part.
  • the table top portions and all its supporting members can be at any size or length joined rigidly by connection means to each other to form the sofa table. All parts could be of any materials, could be of plain or incorporated with any external design or crafting in order to improving its appearance for the purpose to attract buyer.
  • a height adjustable or extendable telescopic means with at least one end pivotally connected to the adjustable portion of the said table top, another end pivotally connected to the supporting member of the stationary table portion leg means at the lower part of the said sofa table, acting like an inclined strut supporting load from the said adjustable portion of the table top.
  • the design and placement of the extendable telescopic means is essential in order to provide stability to the sofa table. In general, the pivoting location is best at proximity whereby the said means can provide the best equilibrium support to the table top at any height. If more than one of such telescopic adjustable means are needed to support heavy duty sofa table, these adjustable means can be pivoted at equidistance to share the load so that the table will be at all time in equilibrium state.
  • the extendable telescopic means can be operated either mechanically or electrically, for example those mechanism or system that could provide upward and downward movements like piston and cushion, pneumatic cylinder, tube and rod, threaded cylindrical rod are all could be used.
  • an on board battery is needed in order to supply the necessary power.
  • the latter design is not so favorable as motor as well as the battery have to be periodically serviced, therefore this indirectly will add extra burden to the cost.
  • a height controller or locking means is incorporated unto the height adjustable telescopic means to allow the adjustable portion of the sofa table to be locked at any desired level within the range of the allowable height.
  • the controller or locking means consist a spring, either a gripper or a stopper to lock movements of the adjustable tube.
  • an angled finger lever control fixture loaded with spring is pivoted in at a corner of the bottom side of the adjustable table top to engage and disengage the height controller or locking means along the height adjustable telescopic means.
  • the leg means of the said portion of the table top is engaged in sliding grooves within the said stationary side leg means of the table top.
  • the incorporation of roller and railing system could be included to further assist smoother sliding movements.
  • Extra members incorporated unto the stationary portion of the table are also intended to counterbalance those extra moment of force created by the extended table top portion to avoid the said table from being toppled.
  • FIG. 1 is a top plan view of the table in its normal position.
  • FIG. 2 is a side view of the table.
  • FIG. 3 is a side view of the table in its height-adjusted position.
  • Fig 4 is a detail of the adjustable telescopic means.
  • FIG 5 is a detail of the mechanism involved when it is in the un-locking mode, whereby the movable top is released to be freely adjusted for the desired height.
  • FIG 6 is a detail of the mechanism involved when it is in the locking mode, whereby the movable top is locked at the desired height.
  • the present invention comprises a sofa table having a top or a portion of that top which can be elevated and to be used as support for eating and writing.
