Locking hinge device for the LCD screen of a word processor
First Claim
1. A locking hinge device for adjusting the screen viewing angle of a word processor having a base and a keyboard cover hinged to the base, the base having a key board fixedly mounted to the front upper face thereof, the keyboard cover having a liquid crystal display (LCD) screen fixedly mounted to the front face thereof, said locking hinge device comprising:
- a horizontal pivot pin attachable to the mid-portion of the upper face of said base rearwardly to said keyboard and extending substantially between the opposing ends of said base;
a pair of elongated hinge members attachable to the opposing ends of said keyboard cover, each of said elongated hinge members having an axial bore at the front end thereof, said axial bore having circumferentially arranged detent receiving recesses on the inner circumference thereof for providing different positions of tilt-angle;
a pair of resilient restraint members fixed to the opposite ends of said pivot pin, each restraint member including a substantially wheel shaped portion received and retained in said axial bore, said substantially wheel shaped portion including a plurality of circumferentially arranged detents on the outer circumference thereof for being positioned in the corresponding ones of said circumferentially arranged recesses, a central bore receiving adjusting screws, slots provided between said central bore and said detents, and slits in communication with said slots and said central bore; and
constraint-force adjusting means having eccentrically located axially elongated interlocking pins received in said slits in said restraint members.

Abstract
A locking hinge device for adjusting the screen viewing angle of a word processor includes a hinge pin to which a keyboard cover is hinged. The keyboard cover has an LCD screen fixed to the front face thereof. The elongated hinge members are integrally formed with the keyboard cover and hinged to the hinge pin. The hinge members have axial bores. The axial bores are constructed to include circumferentially arranged recesses that receive detents which provide a corresponding number of stationary positions for providing different operator viewing angles over a wide range of adjustment. Restraint members are provided with circumferentially arranged detents on the outer circumference thereof for being positioned in the corresponding detent receiving recesses.
