Abstract

Abstract A writing table includes a writing surface countersunk into a working plate. Continuous adjustment of the inclination of the working surface towards a user from being coplanar with the working plate to a maximum angle is achieved through provision of a roller situated beneath a rear portion of the working surface. An adjustable footrest for the writing table that can be manipulated by a user's foot comprises a further roller, the ends of which are supported by left and right profile members having a desired adjustment profile.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 258 words
A writing table comprising: a working plate having an upper surface with a countersunk opening in it; a working surface countersunk into the working plate opening, the working surface comprising a cutout portion of the working plate and having front and rear portions with respect to a user; hinge means at the front of the working surface and in the countersunk opening for rotatably supporting the front of the working surface with respect to the working plate and for continuously varying the inclination of the working surface from being coplanar with the working plate to a maximum angle of inclination; a table-roller situated beneath the working surface and rollable to various positions beneath the working surface for supporting the rear of the working surface at different elevations above the plate, whereby different inclinations of the working surface may be provided; a foot support member comprising a foot-roller extending from left to right from the perspective of the user; and positioning means for adjusting the vertical position of the foot support member and the position of the foot support member towards and away from the user through manipulation by a user's foot, said positioning means comprising a pair of profile members situated to the left and right of a user, said profile members each comprising a plurality of generally-horizontal stages ascending from front to rear from the user's perspective, with a respective, generally-vertical portion being interposed between adjacent horizontal stages, the ends of said foot-roller being adapted to rotate on said profile members under force of a user's foot.
Claim 2
Dependent Claim 258 words
A writing table comprising: a working plate having an upper surface with a countersunk opening in it; a working surface countersunk into the working plate opening, the working surface comprising a cutout portion of the working plate and having front and rear portions with respect to a user; hinge means at the front of the working surface and in the countersunk opening for rotatably supporting the front of the working surface with respect to the working plate and for continuously varying the inclination of the working surface from being coplanar with the working plate to a maximum angle of inclination; a table-roller situated beneath the working surface and rollable to various positions beneath the working surface for supporting the rear of the working surface at different elevations above the plate, whereby different inclinations of the working surface may be provided; a foot support member comprising a foot-roller extending from left to right from the perspective of the user; and positioning means for adjusting the vertical position of the foot support member and the position of the foot support member towards and away from the user through manipulation by a user's foot, said positioning means comprising a pair of profile members situated to the left and right of a user, said profile members each comprising a plurality of generally-horizontal stages ascending from front to rear from the user's perspective, with a respective, generally-vertical portion being interposed between adjacent horizontal stages, the ends of said foot-roller being adapted to rotate on said profile members under force of a user's foot.
Claim 3
Dependent Claim 42 words
