Device for displaying CAD-drawings

Claim 1

A device for displaying CAD drawings comprising: a frame, two lateral end brackets arranged within said frame having an upper section and a lower section, and at least two levers pivotally connecting said two lateral end brackets to said frame; two rollers rotatably mounted between said two lateral end brackets and an endless foil loop rotatably mounted around said two rollers defining a drawing surface; a handle mounted on each of said lateral end brackets adapted for pivoting said drawing surface into a work area of a CAD operator; a plotter pen for dispensing ink; a guide rail mounted between said two lateral parts in the upper section and a head movably supported on said guide rail for holding said plotter pen, said plotter pen and said drawing surface being movable in accordance with a program in two coordinate directions relative to each other for temporarily applying ink to said drawing surface; and an erasing device comprising a brush disposed between said two lateral brackets, in the lower region, for erasing the ink from said foil loop.

Claim 2

A device for displaying CAD drawings comprising: a frame, two lateral end brackets arranged within said frame having an upper section and a lower section, and at least two levers pivotally connecting said two lateral end brackets to said frame; two rollers rotatably mounted between said two lateral end brackets and an endless foil loop rotatably mounted around said two rollers defining a drawing surface; a handle mounted on each of said lateral end brackets adapted for pivoting said drawing surface into a work area of a CAD operator; a plotter pen for dispensing ink; a guide rail mounted between said two lateral parts in the upper section and a head movably supported on said guide rail for holding said plotter pen, said plotter pen and said drawing surface being movable in accordance with a program in two coordinate directions relative to each other for temporarily applying ink to said drawing surface; and an erasing device comprising a brush disposed between said two lateral brackets, in the lower region, for erasing the ink from said foil loop.

Claim 7

A method for repeatedly displaying CAD drawings on a reusable drawing surface, comprising the steps of: mounting a rotating reusable endless foil loop adjacent to a movable plotter; plotting a draft drawing on the endless foil loop by moving the plotter and the endless foil loop in accordance with a program in two coordinate directions relative to each other; erasing the draft drawing with a rotating brush; repeating said steps of plotting and erasing the draft drawing until the draft drawing is finalized; mounting a sheet of paper on the foil loop; and plotting the finalized drawing on the sheet of paper.

Claim 8

A method for repeatedly displaying CAD drawings on a reusable drawing surface, comprising the steps of: mounting a rotating reusable endless foil loop adjacent to a movable plotter; plotting a draft drawing on the endless foil loop by moving the plotter and the endless foil loop in accordance with a program in two coordinate directions relative to each other; erasing the draft drawing with a rotating brush; repeating said steps of plotting and erasing the draft drawing until the draft drawing is finalized; mounting a sheet of paper on the foil loop; and plotting the finalized drawing on the sheet of paper.

Claim 9

A device for displaying CAD drawings comprising: a frame and two lateral end brackets slidably mounted within said frame; a planar board mounted on said two lateral end brackets defining a drawing surface; a plotter pen for dispensing ink; a guide rail mounted on said frame and a head slidably supported on said guide rail for holding said plotter pen, said head and said drawing surface being movable in accordance with a program in two coordinate directions relative to each other for temporarily applying ink to said drawing surface with said plotter pen; and an erasing device movable across said board for removing the ink from the drawing surface.

Claim 10

A device for displaying CAD drawings comprising: a frame and two lateral end brackets slidably mounted within said frame; a planar board mounted on said two lateral end brackets defining a drawing surface; a plotter pen for dispensing ink; a guide rail mounted on said frame and a head slidably supported on said guide rail for holding said plotter pen, said head and said drawing surface being movable in accordance with a program in two coordinate directions relative to each other for temporarily applying ink to said drawing surface with said plotter pen; and an erasing device movable across said board for removing the ink from the drawing surface.
