Abstract
Abstract The invention is a support which can be releasably attached to a table, or the like, and which extends across the table to support the forehead of a person who is leaning over the table engaged in work such as drafting, reading fine print or the like. The device is triply adjustable to conform to the position of the forehead and to swing out of the way when not in use.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
161 words
An elongated headrest comprising: (a) a base having a releasable clamp for attachment to the far edge of a horizontal table; (b) an upright cylindrical stud extending from said base; (c) a vertical bore defined in said boom receiving said stud; (d) a clutch comprising an insert having a wedge-shaped opening engaged over said stud and a pressure-applying member fixed in said boom adjacent said bore to wedge said insert against said stud; (e) said boom defining a short, vertical segment and elongated straight cantilevered segment, said vertical segment defining said bore in its bottom and having an adjustable locking joint at its top connecting two segments together; (f) said upper cantilevered segment being defined in two locking telescoping components; and (g) a forehead cradle mounted on the distal end of said cantilevered boom segment, whereby said headrest is universally adjustable azimuthally, elevationally, and longitudinally, and minimizes stress on said table by virtue of the low-torque attachment to the edge thereof.
