FOLDING WALL TABLE A CEMENT MIXER AND A METHOD OF CONSTRUCTION UTILISING THE SAID MIXER

摘要

A table surface member is movable between a vertical storage position against a wall and a usable position horizontally extending from the wall. The table member connects to the wall by means of a hinge assembly including upper and lower hinge arms which are pivotally connected to the wall and the table. The pivotal connections of the upper and lower arms to the table are offset so that the pivot axis of the lower arm 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 arms provides an overcenter resistance force to the movement of the table as it passes through an intermediate position near the vertical storage position, thereby eliminating the need for a separate latch or counterbalance to hold the table in its storage position.
