Abstract
Abstract A system for setting up a data display device on a work surface, functions for elevation adjusting, for rotating, and for swivelling the data display device. The system, which is particularly economical, has a stand with a telescope member adjustable in height thereon. A base plate is attached thereupon, and a rotary plate is supported on the base plate. The rotary plate has an arch 5 upon which sliding elements are guided, and to which the data display device is fastened.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
341 words
A system for setting up a data display device on a work surface, comprising: an elevation adjustment means; rotation means for rotation of the device about a vertical axis; swivel means for swivelling or tilting the device about a horizontal axis; a weight balancing means for compensating at least a portion of a weight of the data display device; a stand having a stationary telescope member and an extendable telescope member in cooperation therewith; a base plate arranged on the extendable telescope member which receives a rotary plate in rotary fashion; said swivel means comprising the rotary plate provided with an arch, and at least two sliding elements arranged on the arch for bearing the data display device; said weight balancing means comprising a substantially linear energy storage member arranged on the stand; said elevation adjustment means comprising a toothed rack arranged on the extendable telescope member and a pinion which engages in the toothed rack, said pinion being arranged on a shaft which is provided with a first control knob located on the stationary telescope member; the base plate having a passage for the linear energy storage member and at least two concentrically arranged base plate guide slot means for guiding rotation of the rotary plate; two rotary plate guide slot means corresponding to the two sliding elements of the swivel means which run in a direction of the arch for guiding the sliding elements; said swivel means comprising two outside supports or abutment members lying opposite the sliding elements at the rotary plate guide slot means, and first connection element means aligned through the rotary plate guide slot and which holds the sliding elements and the outside abutment members in a releasable connection; second connection element means passing through said base plate guide slot means and which hold the rotary plate to the base plate in a releasable slidable connection to permit rotation of the rotary plate relative to the base plate; and said second connection element means including a screw with a nut designed as a control knob.

Claim 3
Dependent Claim
45 words
A system according to claim 1 wherein the linear energy storage member is prestressed with a force which corresponds at least to a sum of a weight of the extendable telescope member and all objects arranged thereupon, as well as a frictional force associated therewith.
Claim 4
Dependent Claim
26 words
A system according to claim 1 wherein the linear energy storage member is designed as a pneumatic spring with a pressure tube and a piston rod.
Claim 5
Dependent Claim
45 words
A system according to claim 3 wherein a bottom base plate is arranged under the stand, the pressure tube of the pneumatic spring is mounted on the bottom base plate, and its piston rod is mounted in a bearing bushing positioned on the rotary plate.
Claim 6
Dependent Claim
85 words
A system according to claim 1 wherein said first control knob comprises a first rotary element connected with said shaft by a first connection element, and a second rotary element connected with the first in a torsionally fixed manner, on a side pointing to the stationary telescope member a rim which partially encompasses the first rotary element, a spring element between the first rotary element and the rim, and a brake element between the rim of the second rotary element and the stationary telescope member.
Claim 7
Dependent Claim
36 words
A system according to claim 5 wherein the brake element comprises a perforated disk, and that the stationary telescope member has at least one part for engagement into one of the perforations of the perforated disk.
