  • Patent number: 5322022
    Abstract: A collapsible table is provided with one side that is adapted for pivotal attachment to a wall and having two legs extending from the other side that can be readily folded under the table while the table is simultaneously lowered flush against the wall. A locking member is pivotally attached to the underside of the table top that spans between both legs and is rotatable from a first position where it locks both legs vertically underneath the table top, and a second position where the front legs are free to be folded against the underside of the table top. A collapsing line is attached to one front leg, through the midpoint on the locking member, and to the other leg such that when the midsection of the collapsing line is pulled, it pulls the front legs up underneath the table top which allows the table top to be simultaneously lowered to its collapsed position flush with the wall.
