Abstract

Abstract A holder for adjustably positioning a flat-sheet magnifier proximate a visual display terminal comprises a mounting for retaining the magnifier and a support for extensibly positioning the mounting in a predetermined, spaced-apart relationship with the terminal. Disclosed are particular arrangements of mounts and supports including slidable members, telescopic legs and pivoting, scissor-action legs, all of which provide for the positioning of a magnifier proximate a display screen.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 61 words
A holder for adjustably positioning a flat sheet magnifier proximate a visual display terminal comprising: mounting means for retaining said magnifier therein; and means for supporting and extensibly positioning said mounting means in a predetermined spaced-apart relationship with said terminal, said means including at least two legs each leg having telescoping segments, said legs being operative to extensibly position said magnifier.
Claim 2
Dependent Claim 61 words
A holder for adjustably positioning a flat sheet magnifier proximate a visual display terminal comprising: mounting means for retaining said magnifier therein; and means for supporting and extensibly positioning said mounting means in a predetermined spaced-apart relationship with said terminal, said means including at least two legs each leg having telescoping segments, said legs being operative to extensibly position said magnifier.
Claim 3
Dependent Claim 170 words
A holder for adjustably positioning a flat sheet magnifier proximate a visual display terminal comprising: mounting means for retaining said magnifier therein comprising at least two diametrically opposing frame members, said members having an interior side and an exterior side, said interior side being configured to receive said magnifier therein and said exterior side defining a first channel therein; and means for supporting and extensibly positioning said mounting means in a predetermined, spaced-apart relationship with said terminal, said means including at least two base members parallel to said at least two frame members of said mounting means, each base member having an interior side and an exterior side, said exterior side defining a second channel therein, said means further including at least two legs, each leg having two ends and a centerpoint therebetween, said legs pivotally intersecting at said centerpoints and said ends being secured in said first and second channels, whereby said mounting means is extensibly positioned by pivoting said legs from a first position to a second position.
Claim 4
Dependent Claim 170 words
A holder for adjustably positioning a flat sheet magnifier proximate a visual display terminal comprising: mounting means for retaining said magnifier therein comprising at least two diametrically opposing frame members, said members having an interior side and an exterior side, said interior side being configured to receive said magnifier therein and said exterior side defining a first channel therein; and means for supporting and extensibly positioning said mounting means in a predetermined, spaced-apart relationship with said terminal, said means including at least two base members parallel to said at least two frame members of said mounting means, each base member having an interior side and an exterior side, said exterior side defining a second channel therein, said means further including at least two legs, each leg having two ends and a centerpoint therebetween, said legs pivotally intersecting at said centerpoints and said ends being secured in said first and second channels, whereby said mounting means is extensibly positioned by pivoting said legs from a first position to a second position.
Claim 5
Dependent Claim 88 words
A holder for adjustably positioning a flat sheet magnifier proximate the screen of a visual display terminal, said holder comprising: mounting means defining a channel for receiving and retaining said flat sheet magnifier; a retaining block configured to be secured to said terminal, one of said mounting means and said retaining block including a pair of spaced apart openings therethrough; and a pair of elongated rod-like support arms operable to engage said openings so as to slidably join said one of said mounting means and said retaining block.
Claim 6
Dependent Claim 88 words
A holder for adjustably positioning a flat sheet magnifier proximate the screen of a visual display terminal, said holder comprising: mounting means defining a channel for receiving and retaining said flat sheet magnifier; a retaining block configured to be secured to said terminal, one of said mounting means and said retaining block including a pair of spaced apart openings therethrough; and a pair of elongated rod-like support arms operable to engage said openings so as to slidably join said one of said mounting means and said retaining block.
