  • Patent number: 7814708
    Abstract: There is provided a portable riser having an operator actuated lifting assist assembly operatively coupled to a riser deck. In one aspect, there is a first pivot mechanism coupled to a first support leg and adapted to initiate upward movement of the portable riser from a collapsed position when a downward force is applied to the first support leg, and a second pivot mechanism coupled to a second support leg and adapted to continue the upward movement. The lifting assist assembly provides a lifting force that continues upward movement to an upright position where the portable riser in locked. There is included a riser unlocking means for unlocking the lifting assist assembly. The portable riser remains in the upright position until the riser unlocking means is operated and a collapsing force is applied to the portable riser sufficient to overcome the lifting force and enable collapsed of the portable riser.

  • Patent number: 7448330
    Abstract: There is provided an apparatus for a folding table assembly comprising a lifting assist center torsion bar assembly, a lift off caster assembly and a stability locking mechanism. A folding table assembly with a lifting assist mechanism provides a lifting assist force during a portion of the folding process of a foldable table from an unfolded use position to a folded storage position. A lift off caster assembly maintains an unfolded table assembly in a stationary position and prevents the unfolded table from wandering or deviating from its original location on the floor. There is also provided a stability locking mechanism that can set the folding table in a folded and stable semi-closed position.
