An adjustable work surface support for use with a primary work surface and a secondary work surface comprising primary work surface connecting means; secondary work surface connecting means; a parallelogram link support comprising a support bar mounted to the primary work surface connecting means to define a first axis; and a pair of parallel arms, each arm attached at one end to the support bar and a second end attached to the secondary work surface connecting means to define a second axis; a connecting plate; attached adjacent one of the parallel arms to the primary and secondary work surface connecting means; having a first pivot point rotatable about the first axis and a second pivot point being rotatable about the second axis; such that when the arm is pivoted about the first axis, an angular position of the secondary work surface with respect to the primary work surface is substantially constant.

L'invention concerne un support de surface de travail réglable à utiliser avec une surface de travail principale et une surface de travail secondaire et comprenant des moyens de connexion de la surface de travail principale; des moyens de connexion de la surface de travail secondaire; un support de liaison en parallélogramme comprenant une barre support montée sur les moyens de connexion de la surface de travail principale, aux fins de définition d'un premier axe; et deux segments parallèles, chaque segment étant fixé au niveau d'une extrémité sur la barre support et une seconde extrémité étant fixée sur les moyens de connexion de la surface de travail secondaire, de manière à définir un second axe; une plaque de connexion; fixée de manière adjacente à un des segments parallèles aux moyens de connexion des surfaces de travail principale et secondaire; comprenant un premier point de pivot rotatif autour du premier axe et un second point de pivot rotatif autour du second axe; de manière que quand le segment est pivoté autour du premier axe, une position angulaire de la surface de travail secondaire par rapport à la surface de travail principale soit sensiblement constante.
