Abstract: A work table or office desk having two pairs of support arms which are pivotable attached on a cross brace of the table frame. The support arms comprise two support arm halves which enclose each one of two rails of the cross brace by grooves such that the support arm is captively maintained, but can be adjusted at a preset pivot angle. A definite lockable setting of the support arms in the set pivot position is obtained in a simple manner where at least one support arm half of each support arm is provided with a denticulation in the area of the groove, the segment element has a counter-denticulation which is in engagement with the denticulation of the support arm half, and a pre-stressed resilient element, in a loosened state of a bolt connection holding said support arm halves together, pulls the support arm halves together and adjustably maintains a functional connection of the denticulation and the counter-denticulation by a limited resilience.

Abstract: The invention relates to a table with a table frame and a tabletop, which is settable in both height and inclination by a control device. Varying the height and inclination of the tabletop with a simple control device and a support frame is accomplished by providing that the control device has two support devices. The two support devices are pivotally attached to the support frame in the upper region of the middle cross member of the support frame about transversely extending pivot shafts. The support devices on the underside of the tabletop are supported on the tabletop about transversely extending pivot shafts, but are guided adjustably within the depth of the tabletop. The control device selectively raises the support devices individually or in common upward in the direction of the tabletop or lowers them individually or in common downward in the direction of the support frame, in the course of which platform-shaped pivot shafts of the support devices move toward or away from one another.
