Abstract
Abstract A worktable with a working surface which can be adjusted in height and/or inclination, which is connected with a table mount by means of an adjustment mechanism. A worktable which can be constructed of individual parts and which can be expanded in width and joined to modular systems is provided by the table mount being a base frame with two supporting columns arranged in the interval of table width and two preferably U-shaped leg members having a central joining portion, a base leg and supporting leg whereby the supporting columns are firmly connected with each other by at least one transverse connecting member and said central joining portion of said leg members adapted to be connected to said supporting columns of said base frame and that said adjustment mechanisms are mounted on the underside of said work surface between said support legs of said leg members and adapted to be connected to said supporting legs.
