Abstract: The invention concerns a table, in particular for video workstations, having a height-adjustable tabletop with at least one vertical guide strut (2), furthermore having a table frame (3) with at least one table support (4) for the guide strut (2) which telescopes within it, and having at least one adjustable spring leg (5) which is arranged between the table frame (3) or the table support (4) and the height-adjustable table elements (1, 2) and has a spring. In addition, a measuring device (25) for determining the particular load on the tabletop (1) is provided, an adjusting device (9) for a spring-leg base (8) on an adjustable spring leg (5) being activated as a function of load values determined.

Abstract: A desk has a vertically adjustable top and at least one vertical guide member movable upwardly and downwardly on a support or frame. A spring leg is disposed between the frame and vertically adjustable desk components. The spring leg is pivoted at one end to a guide member and its other end is braced against a curved rail. The braced end is movable on the rail and lockable in positions corresponding to accommodate various loads on the desk top. The curve of the rail is chosen so that in any position of the braced spring end, the vertical components of force acting on the guide member are equal, at least in two opposite end positions of the desk top. This results in equilibrium in each vertical position for every load on the desk top, after the spring leg has been adjusted.

Abstract: Disclosed is a container (1) is provided with a removable lid (2). At the top of the side wall of the container there is provided an outwardly projecting bead or bead portions (5, 5', 5") abutted by the lid (2) the lid having a skirt (2a) with downwardly and/or inwardly facing cams (10, 11, 12, 15, 16, 17). The lid (2) is relatively stiff, and the inside of the skirt (2a) has a concave abutment surface (2a') near its lower edge portion, the abutment surface being of a substantially spherical, conical or superelliptical curvature and abutting the bead or bead portions (5, 5', 5"). The side wall of the container is provided with a support shoulder (7) beneath the bead or bead portions (5, 5', 5").

Abstract: A spring system for providing an elastic force between two machine parts, including concentric compression and tension springs disposed in parallel within a housing, with one pair of corresponding ends of the springs being connected by a movable coupling piece, and the other pair of corresponding ends being connected to a stationary stop and a connecting element, whereby a movable stop permits variation of the effective point of connection between the compression spring and machine part connected therewith.

Abstract: A mechanism is described for mounting between two parts, such that the mutual distance between the parts may be varied. The mechanism includes a bar pivotally journalled in a bearing at one end and interconnected to an actuating device. The actuating device is pivotally suspended to one of the structures at one end and is connected to the bar at the other end. The pivot axis of the bearing extends obliquely to a plane containing the suspension point of the actuator and the point of connection between the actuator and the bar.

Abstract: A mechanism for raising and lowering a seat, especially designed for handicapped persons, comprises two supporting arms (A', B') which are both at one of their ends coupled to the seat (E), at the front and rear edge thereof, respectively. At their other end, the supporting arms (A', B') cooperate with a fixed point (1', 2') each. At least one of the supporting arms is coupled to a driving member and the two supporting arms (A', B') are interconnected at a point between their ends. With a view to obtaining a space-saving but all the same stable mechanism allowing a physiologically correct trajectory of the seat during its raising and lowering, the supporting arms (A', B') are directly pivotally interconnected (D), and one of the supporting arms cooperates with the fixed point in such a manner that it is displaceable in relation to said point.
