Abstract
Abstract An improved rotary stand, particularly intended to be used as a work table to support a table computer terminal and comprising a disc which is rotatably mounted on a thrust bearing. The disc is provided with a pull-out leaf. The leaf is movable between an inner end position for use when the stand is to be rotated, and an outer end position for use when work is to be carried out on the computer terminal. In the inner position, the leaf will be located interiorly of the edge of the stand in order not to prevent the rotational movements of the latter. The leaf is provided with feet which, in the outer position of the leaf, are arranged to abut against the support.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
190 words
An improved rotary stand for a computer terminal or the like comprising a support disc adapted to support a computer display or its upper face, a thrust bearing provided on the lower face of said support disc, said thrust bearing consisting of two relatively rotatable sections one of which rests in substantially direct contact with a base, such as a table, said rotary stand being configured to serve as a working table to support the computer comprising a display and a keyboard, the improvement comprising said support disc provided with a leaf for support of the computer keyboard, said leaf slidably supported by said support disc to be pulled outwards from the support disc into a keyboard utilizing position, in which position said leaf having supporting means to abut against the base upon which said support disc is positioned and prevent rotation of said support disc, said leaf being arranged to be displaced from the pulled-out keyboard utilizing position inwards over the support disc wherein said supporting means is out of contact with the base to facilitate rotation of the rotary stand and setting thereof in a different angular position.
Claim 2
Dependent Claim
190 words
An improved rotary stand for a computer terminal or the like comprising a support disc adapted to support a computer display or its upper face, a thrust bearing provided on the lower face of said support disc, said thrust bearing consisting of two relatively rotatable sections one of which rests in substantially direct contact with a base, such as a table, said rotary stand being configured to serve as a working table to support the computer comprising a display and a keyboard, the improvement comprising said support disc provided with a leaf for support of the computer keyboard, said leaf slidably supported by said support disc to be pulled outwards from the support disc into a keyboard utilizing position, in which position said leaf having supporting means to abut against the base upon which said support disc is positioned and prevent rotation of said support disc, said leaf being arranged to be displaced from the pulled-out keyboard utilizing position inwards over the support disc wherein said supporting means is out of contact with the base to facilitate rotation of the rotary stand and setting thereof in a different angular position.
Claim 3
Dependent Claim
46 words
A rotary stand as claimed in claim 1, wherein said supporting means comprises feet provided on the lower face of said leaf, said feet being arranged to abut against the base only when said leaf is in its pulled-out position corresponding to the keyboard utilization position.
Claim 4
Dependent Claim
49 words
A rotary stand as claimed in claim 1, comprising a support ring provided on the lower face of said support disc, said support ring having a height slightly smaller than the height of said thrust bearing and adapted to engage the base for limiting tilting of said support disc.
Claim 5
Dependent Claim
63 words
A rotary stand as claimed in claim 1 wherein the support disc has a generally circular configuration with a cutout formed in one side thereof in which the leaf is supported, said cutout and said leaf being configured so that when said leaf is in its inward position, it does not extend beyond the radius of the circular portion of said support disc.
Claim 6
Dependent Claim
46 words
A rotary stand as claimed in claim 4, wherein said supporting means comprises feet provided on the lower face of said leaf, said feet being arranged to abut against the base only when said leaf is in its pulled-out position corresponding to the keyboard utilization position.
Claim 7
Dependent Claim
49 words
A rotary stand as claimed in claim 5, comprising a support ring provided on the lower face of said support disc, said support ring having a height slightly smaller than the height of said thrust bearing and adapted to engage the base for limiting tilting of said support disc.
Claim 8
Dependent Claim
25 words
A rotary stand as claimed in claim 1 wherein the leaf has an upturned flange at its outer peripheral edge for retaining a keyboard thereupon.
Claim 9
Dependent Claim
