Abstract: The invention relates to an articulated bracket for supporting especially office equipment, such as screens, telephones and the like, in variable positions. The inventive bracket comprises a base part (2) which is secured in a fixed position, a lower bracket part (4) which is connected to said base part via a first joint (8) in such a way that it can pivot, and an upper bracket part (6) which is connected to said lower bracket part (4) via a second joint (10) in such a way that it too can pivot. Said upper bracket part (6) is connected to the base part (2) by means of a pull element (16), said pull element being guided via the joints (8, 10). Elastic means (18) are arranged in such a way that a carrying force (F) is produced to support the bracket parts (4, 6).

Abstract: A holder for supporting a piece of equipment above a surface has a column fixed to the surface, projecting upward therefrom, and having an upper end defining an inner horizontal pivot axis, an inner arm having an inner end pivoted at the inner axis on the column and an outer end defining an outer horizontal pivot axis, and an outer arm having an inner end pivoted at the outer axis on the inner-arm outer end and an outer end provided with a support for the piece of equipment. A link has an inner end seated in the upper end of the column at a location spaced a predetermined relatively long distance from the inner axis and an outer end seated in the inner end of the outer arm at a location space a predetermined relatively short distance from the outer axis. Thus as the inner axis is lifted the angle formed between the support and the horizontal increases.

Abstract: An adjustable copyholder comprises a base and a cantilever arm having a plurality of cantilever arm segments attached thereto, and a copy support plate mounted at the free end of the cantilever arm. The cantilever arm is connected pivotally to the base. The cantilever arm segments are connected pivotally with each other. The copy support plate is connected pivotally to the cantilever arm. The pivot joints used to extend the cantilever arm have single pivot axes which are parallel to each other, horizontal and transverse to the cantilever arm, wherein these pivot joints are manually adjustable, at least controllable frictionally, the pivotability of the cantilever arm segments connected pivotally with each other being associated with a securing mechanism for each pivot joint.
