Patent number: 6313594Abstract: A drive system for a partition wall system composed of several individual components which are horizontally movable via rollers or appropriate media at or in a guide rail mounted to a ceiling in a way or technique in which the individual components present separate drive media which convey the corresponding component(s) independently from and/or simultaneously with the other components along the guide rail. A central control unit combined with a microprocessor and several memories is provided and the control unit's output signal transmits data and addresses to all drive media via at least a two-wire connection (databus) simultaneously to activate the individual component's drive media, which allows the individual control and regulation of the individual components and the additional miscellaneous functions for the individual components respectively inside the individual components.

Patent number: 6286258Abstract: A movable wall has a plurality of movable wall elements mounted in horizontally oriented guide rails. The guide rail which defines the path of the movable wall elements from the parked position into the closed position is laid out in a 90 degree curve in the vicinity of a room opening to be closed so that it brings the closed movable wall elements into alignment. The final movable wall element in the direction of the closing motion is mounted on support and guidance elements. At least the rear support and guidance element of the final wall element in the direction of the closing motion, is mounted on the final movable wall element so that the rear support and guidance element can be moved along the final movable wall element. This rear support and guidance element also has its own drive unit, by which drive unit, during the closing process, the final movable wall element is automatically moved into the closed position in which it is flush with the other movable wall elements.Type: GrantFiled: February 19, 1998Date of Patent: September 11, 2001Assignee: DORMA GmbH + Co.

Patent number: 6286277Abstract: A sliding panel system whose sliding panel elements are aligned in a row next to each other when the sliding panel is closed and are positioned orthogonally in relation to the sliding panel when it is in its parked position. The individual sliding panel elements are guided on a first rail arrangement, a curved or bent rail section being adjacent to said slide rail in the transitional area leading to the parked position. The invention is characterized in that the slide rail has a curved or bent rail section in the transitional area leading to the parked position itself. When a point is switched immediately, said rail section opens up onto a parking rail running orthogonally or at an angle to the slide rail. The free end of the parking rail is configured so that it extends into the area of the sliding panel.Type: GrantFiled: February 4, 2000Date of Patent: September 11, 2001Assignee: Dorma GmbH + Co. KGInventors: Ernst-Udo Blöbaum, Reinhard Janutta

Patent number: 6266922Abstract: A revolving door with a ceiling drive beam that is integrated into the ceiling construction, whereby the ceiling construction consists of two circular segments. The ceiling drive beam is located between the segments and is continuous over the inside diameter of the face band and is connected on the face side to the face band. The result is a component that braces and stiffens the ceiling construction, so that other elements of the ceiling construction, such as the struts that support the face band, can be realized lighter in weight and can be manufactured more economically. When the ceiling drive beam is adapted to accommodate face bands of different diameters, all that is necessary is an elongation of the ceiling drive beam on the end, while retaining its cross section.Type: GrantFiled: April 11, 2000Date of Patent: July 31, 2001Assignee: DORMA GmbH + Co. KGInventor: Manfred Rockenbach
