摘要:
A table surface member is movable between a vertical storage position against a wall and a usable positioned horizontally extending from the wall. The table member connects to the wall by means of a hinge assembly which permits folding of the table such that the upper edge of the table in the storage position is the edge adjacent the wall in the usable position. In a preferred embodiment latch means are provided for latching the edge of the table to the wall or wall mounting bracket in the usuable position, so that no supporting legs for the outer end of the table are required. Alternatively, another disclosed embodiment uses folding legs to support the outer edge of the table in the usuable position. A preferred hinge assembly includes upper and lower hinge arms pivotally connecting to the wall and the table. The pivotal axis of the lower arm or arms to the table is spaced below a plane passing through the pivot axis of the upper arm to the table and parallel with the table surface. This offset plus intentional length mismatching of the hinge arms provides an overcenter resistance force which holds the table in its storage position without the need for a separate latch or counterbalance.
