摘要： A work top is height adjustable and may tilt about a horizontal axis near the front edge. The work top may be mounted on an open office beam system or an office screen or partition in cantilever fashion or it may be a free standing unit. The work top is mounted for horizontal sliding movement and tilting on a horizontally extending undercarriage. The undercarriage includes an inclined strut journalled for sliding movement in a normally fixed inclined strut. A cable reeving system interconnects the work top and fixed inclined strut to maintain the work top in the same horizontal position regardless of its elevation. One or more tension springs, the tension of which may be adjusted, interconnect the under carriage and work top to counterbalance the weight of the work top and what may be positioned thereon such as a computer. A releasable latch locks the work top to the under carriage so that the work top may be locked in its height adjusted position. When the latch is released a light pull or push on the under carriage adjusts the work top to the desired height within its range of adjustment.

摘要： A fold out display is particularly adapted to support a wide variety of different types of group work activities, team projects, and the like, and includes a free standing base which fixedly supports a primary panel having an exterior display surface. At least one foldable panel is hingedly supported on the primary panel for movement between a closed folded position overlying the primary panel, and an open unfolded position protruding outwardly coplanar with the primary panel. The foldable panel includes at least an interior display surface which overlies the display surface of the primary panel when in the closed folded position. A one-piece living hinge has opposite side portions connected with the side edges of the primary and foldable panels, and is shaped such that when the foldable panel is shifted into the open unfolded position, the two display surfaces are juxtaposed in a substantially contiguous relationship to collectively provide an enlarged generally continuous and uninterrupted display. A fold out header panel assembly may be provided above the primary panels, and a pair of telescoping outstops help retain the folding panels in their open unfolded position.

摘要： A mobile table system is provided in which multiple tables can be juxtaposed in many different configurations to facilitate a wide variety of both group and individual activities. Each table has a top with oppositely oriented side edges shaped to abut flush with the side edges of like tables, an outer marginal edge configured to accommodate a user thereby, and an inner marginal edge with a generally concave shape which defines a central space when aligned with the inner marginal edges of like tables. Each table includes legs to support the same freestanding on a floor surface. A first one of the legs depends from the top adjacent the outer marginal edge thereof and has a foot at the lower end thereof, and a second one of the leg depends from the top adjacent the inner marginal edge thereof and has a roller at the lower end thereof, so as to permit manual translation of the tables across the floor surface in a wheelbarrow fashion. A latch arrangement may be provided to detachably interconnect like tables in a manner which enables the same to be readily pulled apart.
