  • Patent number: 5013106
    Abstract: A plinth drawer comprises a bar which projects at the front upper edge and onto which a front piece attaches. The drawer also has a holder which is set back in relation to the bar, for a plinth panel. The holder is formed by two adaptors which are constructed as plastic moldings, which can be fastened to the plinth panel and which are clamped to the frame of the drawer. This construction permits simple assembly of the plinth panel and adaptation of the plinth offset to correspond to any furniture range.

  • Patent number: 4832300
    Abstract: A rotating base for furniture which is provided with a pull-out system is fitted with a member which is attached to the body of the furniture so that it rotates about a vertical axis, whereby runway rails to support the rotating base are fitted to the member. The rotational movement of the member in relation to the body of the furniture is coupled by a coupling mechanism in such a way to the linear pulling out movement of the rotating base in relation to the member, that the rotating base cannot strike against the body of the funiture in the pulled-out position.

  • Patent number: 4783130
    Abstract: A rotatable compartment floor (10) for corner cupboards or the like has a circular contour or a contour in the form of a circular sector and is provided at the circle center with a hub (12) and at the outer edge with a peripheral wall (14) projecting vertically upwards. To divide the surface of the compartment floor into several compartments, there is at least one radial wall element (20) which at its outer end (32) is supported on the peripheral wall (14) and at its inner end has an end piece (24) in the form of a circular arc which surrounds the hub (12) and which engages in a continuous groove (28) in the hub by means of a flange (26) projecting horizontally inwards.

  • Patent number: 4693188
    Abstract: A rotatable shelf insert for corner cupboards comprising at least one shelf of substantially circular overall shape. A guide rod passes through a hub in the center of the shelf. The shelf is supported on the guide rod by means of a retaining pin passing through the guide rod at right angles. The hub receives the guide rod with radial play. A cylindrical clamping sleeve conically tapered at one end by variation of the wall thickness is inserted between the guide rod and the inner wall of the hub.

  • Patent number: 4609236
    Abstract: A drawer for cupboards comprises a baseplate (10) guided displaceably in lateral guide rails, a frame (14) surrounding the baseplate at its lateral and rear edges, and an adjustable front plate (12) closing the drawer off at the front. Simple adjustment of the front plate (12), without prior dismantling of individual parts, becomes possible because the frame (14) is designed as a self-supporting part to be fastened to the baseplate (10), and because devices (30, 32) for the adjustable fastening of the front plate are provided at the ends of the frame (14) which face the front plate. This ensures, at the same time, that the frame, including the fastening and adjusting devices for the front plate forms together with the remaining parts (10, 12) of the drawer a smooth-surface structure.
