Abstract An upright standard is provided having front and rear sides and mounting means on its lower end for releasable mounting from a support upon which a typewriter may be placed. A generally horizontal panel structure is mounted from the upper end portion of the standard and projects to the rear of the standard for overlying the keyboard of a typewriter disposed on the support immediately to the rear of the standard and for blocking the area of the keyboard from the area of forward and downward vision of a person seated in front of the support for typing on the typewriter. The horizontal panel structure includes a rear marginal edge portion and a panel extension extends along the rear marginal portion of the panel structure and is supported therefrom for adjustable angular displacement relative to the panel structure about an axis at least closely adjacent and generally paralleling the rear marginal edge portion of the panel structure. Also, the upright standard includes a horizontal transverse bar supported therefrom intermediate its upper and lower ends and the bar is vertically adjustable along the standard with the opposite end portions of the bar projecting outwardly from the corresponding sides of the standard. The bar is provided for establishing the minimum desirable elevation of the wrists of a person typing on the typewriter.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
176 words
An upright standard having front and rear sides and mounting means on its lower end for releasable mounting from a support upon which a typewriter may be placed, a generally horizontal panel structure pivotally mounted from the upper end portion of said standard and projecting to the rear and outwardly beyond the lateral sides of the standard for overlying the keyboard of a typewriter disposed on said support immediately to the rear of and generally laterally centered relative to said standard for blocking the area of the keyboard from the area of forward and downward vision of a person seated in front of the support for typing on the typewriter, a horizontal transverse bar supported from the vertical mid-portion of said standard and vertically adjustable along the latter with the opposite end portions of said bar projecting outwardly from the corresponding sides of said standard, said bar being vertically adjustable along said standard for establishing the minimum desirable elevation of the wrists, positioned on opposite sides of said standard, of a person typing on said typewriter.
Claim 2
Dependent Claim
176 words
An upright standard having front and rear sides and mounting means on its lower end for releasable mounting from a support upon which a typewriter may be placed, a generally horizontal panel structure pivotally mounted from the upper end portion of said standard and projecting to the rear and outwardly beyond the lateral sides of the standard for overlying the keyboard of a typewriter disposed on said support immediately to the rear of and generally laterally centered relative to said standard for blocking the area of the keyboard from the area of forward and downward vision of a person seated in front of the support for typing on the typewriter, a horizontal transverse bar supported from the vertical mid-portion of said standard and vertically adjustable along the latter with the opposite end portions of said bar projecting outwardly from the corresponding sides of said standard, said bar being vertically adjustable along said standard for establishing the minimum desirable elevation of the wrists, positioned on opposite sides of said standard, of a person typing on said typewriter.
Claim 3
Dependent Claim
76 words
The combination of claim 1 wherein said panel structure includes a rear marginal edge portion, a panel extension extending along said rear marginal portion and supported therefrom for adjustable angular displacement relative to said panel structure about an axis at least closely adjacent and generally paralleling said rear marginal portion, said panel extension being adjustable as a rearward extension of panel structure for blocking the copy being typed in the typewriter from said area of vision.
Claim 4
Dependent Claim
43 words
The combination of claim 1 wherein said standard includes upper and lower sections having lower and upper ends, respectively, secured together in adjustable overlapped relation whereby the effective height of said standard, and thus the elevation of said panel structure, may be adjusted.
Claim 5
Dependent Claim
25 words
The combination of claim 1 wherein said mounting means carried by the lower end of said standard comprises a rearwardly and horizontally opening clamp structure.
Claim 6
Dependent Claim
98 words
The combination of claim 1 wherein said panel structure includes a rear marginal edge portion, a panel extension extending along said rear marginal portion and supported therefrom for adjustable angular displacement relative to said panel structure about an axis at least closely adjacent and generally paralleling said rear marginal portion, said panel extension being adjustable as a rearward extension of panel structure for blocking the copy being typed in the typewriter from said area of vision, wherein said panel structure and said panel extension include coacting means operative to realeasably retain said panel extension in adjusted angular position.
