ABSTRACT:
The adjustable LCD screen assembly for a writing machine includes base and an LCD screen assembly coupled to each other by a hinge assembly. An embodiment of the hinge assembly includes a pivot post and a pair locking set screws, Bellville spring washers, a screw, an anti-rotation washer, a first bracket and a second bracket. The hinge assembly mounts to the base along the first bracket and to the LCD screen assembly along the second bracket. The hinge assembly utilizes a compression mechanism including a spring mechanism to generate frictional force between the elements of the hinge assembly to hold the LCD screen assembly in place with respect to the base under “static conditions,” yet allows for infinite adjustability of the LCD screen assembly, within a given range of motion, under “pivoting conditions.”
