Abstract: A seating implement has a base frame, a sitting surface, a back rest, and a tablet. The tablet is fastened to a support element provided on one side of the base frame by way of a linkage mechanism, so that the table can swivel between a substantially horizontal position of use and a position of non-use. The tablet is dimensioned to support a notebook computer and the support element has a section running in a substantially horizontal plane, on which the tablet is pivotally fastened by way of the linkage mechanism. The substantially horizontal section is oriented at an angle to the direction of the sitting surface, and the tablet can swivel about an axis substantially parallel to this section.

Abstract: A supporting arm for a projection apparatus has first and second arm sections and an articulation apparatus therebetween for interconnecting the arm sections. The projection apparatus can be fastened on a free end of the second arm section. The articulation apparatus permits the second arm section to rotate relative to the first arm section between a first position, in which the longitudinal axes of the arm sections run substantially mutually parallel, and a second position, in which the longitudinal axes of the arm sections run substantially mutually at right angles. A spring apparatus is coupled to the arm sections and has a spring force selected to compensate for a weight force of the second arm section and of the projection apparatus fastened thereon over substantially an entire rotational excursion of the second arm section relative to the first arm section. A presentation apparatus having the supporting arm is also provided.

Abstract: A height positioning device for a presentation device contains a carrier to which a presentation element can be fastened, and a mount to which the carrier is attached and movable between first and second height positions. Also provided are a flexible traction mechanism having one end fastened to the carrier and a second end fastened to the mount or a stationary element, and a deflection element around which the traction mechanism is guided in the manner of a pulley. To hold the carrier at any desired position, the height positioning device contains a gas compression spring having a first end fastened to the deflection element and a second end supported on the mount, an element of fixed height, on the carrier or an element which can be moved with the carrier, such that the spring compensates for a weight of the carrier and the presentation element.

Abstract: Proposed is a connecting device for connecting a table leg to at least one frame member, wherein both the table leg and also the frame member are in the form of a hollow profile at least in the region adjoining the connecting device, which has a profile body; a first extension which is connected to the profile body, which is coaxial with respect to a frame member, and whose outside diameter substantially corresponds to the inside diameter of the hollow profile of the frame member; and a second extension which is connected to the profile body, which is coaxial with respect to a table leg, and whose outside diameter substantially corresponds to the inside diameter of the hollow profile of the table leg. Such a connecting device makes it possible to provide an article of table furniture which is very stable in respect of shape in spite of a lightweight structure.

Abstract: An adjustable table system, particularly for conference or office tables, has at least one table leg with a table leg strut that can be attached from below the table top in one of several predetermined positions by sliding a first member with two spaced apart rows of longitudinally spaced engagement noses into engagement with a second member fixed to the underside of the table which also has two laterally spaced apart rows of longitudinally spaced engagement noses, wherein the noses of the first and second members are slidingly mated and secured in a mating position by a rotary locking mechanism. The table leg also has telescoping inner and outer tubes with a plastic bushing interposed therebetween and a setscrew mechanism at the top, with the leg being adjustable in the longitudinal direction by direct operation of the set screw from the top of said table leg or by rotating the outer tube in relation to the inner tube.
