The invention relates to a frame for supporting a top 4, 12 of a table or desk at a working height, said frame being designed for fastening legs 6, 9, in particular for height-adjustable legs 6, 8 of a desk. In order to reduce the storage costs for different table or desk sizes, the frame has a movable, in particular longitudinally movable design.

A height adjustable table can include a plurality of legs, a lower portion, a worksurface, a height adjustable surface, and a linkage. The worksurface can be supported by the plurality of legs and can include a fixed surface and a height adjustable surface. The fixed surface can be secured to at least one of the lower portion and the plurality of legs, and the fixed surface can define a recessed portion. The height adjustable surface can be movable between a raised position and a lowered position so that the height-adjustable surface retracts into the recessed portion when in the lowered position so that the height adjustable surface is coplanar with the fixed surface. The linkage can be configured to move the height adjustable surface between the lowered position and the raised position so that the height adjustable surface remains parallel to the fixed surface.

A sensor assembly for an electrically adjustable piece of furniture having at least one actuator for adjusting a component and a control for the actuator comprises a light transmitter and a light receiver which are coupled to one another via an optical light path. An aperture element which is configured to at least partially cover the light path and which is mounted in a movable manner with respect to the light path in such a way that a change in a position of the aperture element results in a change in the covering of the light path. An evaluation circuit regulates a light quantity emitted by the light transmitter to a reference quantity by means of a control signal and generates a deformation signal based on the control signal or on a signal derived from the control signal. The aperture element converts a deformation or movement of the component into a change of position of the aperture element relative to the light path.

Slider element for lifting columns, preferably for height-adjustable tables, said lifting columns comprise at least two profiles 10,11 arranged telescopically relative to each other, where the slider element 1 has a first slider 2 and a second slider 3 between which there is a designated breaking line 4. The slider element is mounted with the second slider 3 on the outer side of the inner profile 10, and is subsequently guided into the hollow of the outer profile 11, by which the first slider 2 affixes itself to the inner side of the outer profile and when the two profiles are retracted further, the designated breaking line 4 between the first and the second slider 2,3 will break, by which they appear as two separate sliders mounted on a profile each. Thus, a simplified mounting of the sliders is achieved. In addition, it can be constructed such that the sliders are completely concealed within the lifting column.

A table includes a table top having a frame attached to a lower surface of the table top. The table also includes a first leg having lugs and a second leg having lugs. The lugs of the first leg and the second leg are received in slots of the frame to attach the legs to the table. The legs are telescopically movable to adjust the height of the table top.

A folding table comprises a table top, a table leg, a grounding part supported on the ground or a table top, and a second hinged lock formed for the table leg and the grounding part after the table leg and the grounding part rotate relative to each other, one end of the second hinged lock is connected with the other end of the table leg, the other end of the second hinged lock is connected with the grounding part, the table leg or the grounding part are relative to each other. When rotating in the unlocked state, the second hinged lock locks the table leg and the grounding part at an included angle of 0-90°. The invention has the advantages of convenient storage, transportation or carrying and small occupation space.
