Abstract: A frame for sit-stand-tables comprising a longitudinal member, two height-adjustable legs with at least two telescopic profiles, namely an outer and an inner profile, and with a driving mechanism, driven by a motor unit, comprising an electric motor and a gear. According to the invention the motor unit is arranged in the longitudinal member and connected to the driving mechanism in the height-adjustable legs. Thus, a frame with a simplified construction is achieved. The construction of the legs can be simplified and at the same time the dimensions can be reduced, as it is not necessary to take the building-in of a motor into the legs into consideration. As both legs are driven by a joint motor unit, the electric control can also be simplified as it will not have to drive the two legs synchronously.

Abstract: A frame for sit-stand-tables comprising a longitudinal member (3), two height-adjustable legs (6, 7) with at least two telescopic profiles, namely an outer and an inner profile, and with a driving mechanism, driven by a motor unit (39), comprising an electric motor (46) and a gear. According to the invention the motor unit (39) is arranged in the longitudinal member (3) and connected to the driving mechanism in the height-adjustable legs (6, 7). Thus, a frame with a simplified construction is achieved. The construction of the legs (6, 7) can be simplified and at the same time the dimensions can be reduced, as it is not necessary to take the building-in of a motor into the legs into consideration. As both legs (6, 7) are driven by a joint motor unit (39), the electric control can also be simplified as it will not have to drive the two legs synchronously.

Abstract: The invention relates to a supporting frame with a base unit comprising a compartment at least for partial reception of the housing of the lifting column (79) and a cross member (74) for mounting on the base unit (59). The supporting frame comprises a locking element (94), which when placed in-a locked position exerts a squeezing force between the base unit (59), the lifting column housing and the cross member (74), by which the lifting column housing and the cross member (74) are fixed in the base unit (59). The supporting frame further comprises means for retaining the locking element in the locked position. The lifting columns are of the type, which comprises telescopically arranged profiles with an upper and lower end to which upper end a housing is secured.

Abstract: An axial valve has a housing, an inlet, an outlet, a valve seat between the inlet and the outlet, and a valve element cooperating with the valve seat, and is controlled by a pilot valve arranged between the inlet and the outlet, with the valve element being moveable parallel to a flow path from the inlet to the outlet and surrounding an interior space. Without changing the external measurements of the valve an increased through flow is achieved in that a first section of the flow path leads through the interior space and a pressure space is arranged between the housing and the valve element, in which pressure space in the closed condition of the pilot valve a closing pressure is formed and applied to the valve element.
