Abstract: A folding door storage system for an opening of a closet including a first door panel and a second door panel, which panels are pivotal with respect to one another, and a carrier arrangement which can be moved, in a folded state of the door panels in which they are aligned parallel with one another, together with the door panels into a storage space. In order to achieve a safe guiding and moving of the door panels and in order to be able to use the system also for very large dimensions, the first door panel is mounted for movement transversely with respect to the front side of the closet on a guide rail by means of a guide element, wherein the guide element, in the folded state of the door panels, can be transferred into a second guide rail arranged parallel with respect to an outside wall of the closet. A locking mechanism is mounted on the carrier arrangement, which locking mechanism prevents unintended movements and swivellings of the door panels.

Abstract: A plug-in connection has two wedges (1, 2) with wedge surfaces (4, 4') inclined such that forces are created through the cooperation of the wedge surfaces (4, 4') in directions which are at a right angle to one another. A wobble-free fit in these two directions is achieved in this manner.The fastening of an information carrier (T.sub.1) on posts (P.sub.1) is suggested as a special use, whereby with a short plug-in path of movement, a wobble-free fit of the information carrier (T.sub.1) on the post (P.sub.1) is achieved.

Abstract: Picture-screen apparatus are integrated into a conference table to be viewed by conference participants. The conference table is suited both for video conferences with conference participants who are at different locations and also for normal conferences with participants who are all present at the table. Television cameras needed for video conferences can be removed from the surface of the table, if the table is to be used for normal conferences. The picture-screen apparatus arranged below the table top do not interfere during normal conferences and can also be utilized for bringing visual information of any kind to the participants.

Abstract: A support arrangement, in particular for fastening of walls, adjustable walls, partition wall elements, boards and the like which consist of individual pipe sections. Between two of the pipe sections there is inserted an intermediate piece. The intermediate piece is provided with an annular recess for receiving of fastening elements therein. All pipe sections and intermediate pieces are guyed against one another by a pull rod which extends through all thereof.
