摘要：This covers a table structure having two parallel vertical legs and a tabletop which is tiltable over a predetermined angle, such as 90 DEG . The structure includes pivot means held stationary alongside both legs and two pairs of spring-loaded latching devices associated respectively with the two legs. Each latching device includes a lever and a cam which are held together under constant pressure by a spring. The tabletop may be tilted from a horizontal position to a vertical position by manipulating two of the levers which are respectively associated with the two legs, so that the tabletop may be tilted from its vertical position to its horizontal position by manipulating the other two levers respectively associated with said legs.
