Abstract
Abstract For use with a display unit for a word processing system, apparatus is provided for support of the display unit to allow the operator to easily and quickly change the tilt angle of the display unit and retain the tilt angle after a change thereof. The support and rocking tilt apparatus is mounted to the base of the display unit and includes fore/aft retention by a spur gear form on the upper support unit and a rack gear form on the lower support unit, which co-locates the origin of the arc of the rocker, the center of gravity and the origin of the arc of the pitch diameter of the spur gear of the display unit through the tilt range. Rocker means associated with the gear forms provides side-to-side retention of the support and rocking tilt apparatus. Vertical retention apparatus is combined with a snubbing device, including a spring-loaded friction mechanism, which provides infinite actuation throughout the tilt range.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
227 words
Apparatus for supporting a display housing while providing rocking tilt adjustment, said apparatus comprising: a housing support member operatively connected to said housing; a base member; means for mounting said base member to said housing support member to allow a rolling tilt movement therebetween, said means for mounting including an involute gear form and rocker means; vertical retention means for preventing separation of said base member and said housing support member when upward force is applied to said housing support member, said vertical retention means including a U-shaped bracket attached to said housing support member and positioned such that the open portion of the U-shaped bracket is directed away from the housing support member, each end portion of the U-shaped bracket being formed to provide an arcuate shaped aperture therein, two L-shaped brackets attached to the base member with one end portion of each L-shaped bracket being formed to provide an aperture therein, said L-shaped brackets being positioned with the end portion containing the aperture in operative relationship with the aperture formed in a corresponding end portion of the U-shaped bracket, fastener means operatively positioned through said apertures; said vertical retention means including a spring-loaded friction mechanism operatively associated with said vertical retention means to assure that said housing support member retains its position with respect to said base after a rocking tilt adjustment has been completed.
Claim 2
Dependent Claim
227 words
Apparatus for supporting a display housing while providing rocking tilt adjustment, said apparatus comprising: a housing support member operatively connected to said housing; a base member; means for mounting said base member to said housing support member to allow a rolling tilt movement therebetween, said means for mounting including an involute gear form and rocker means; vertical retention means for preventing separation of said base member and said housing support member when upward force is applied to said housing support member, said vertical retention means including a U-shaped bracket attached to said housing support member and positioned such that the open portion of the U-shaped bracket is directed away from the housing support member, each end portion of the U-shaped bracket being formed to provide an arcuate shaped aperture therein, two L-shaped brackets attached to the base member with one end portion of each L-shaped bracket being formed to provide an aperture therein, said L-shaped brackets being positioned with the end portion containing the aperture in operative relationship with the aperture formed in a corresponding end portion of the U-shaped bracket, fastener means operatively positioned through said apertures; said vertical retention means including a spring-loaded friction mechanism operatively associated with said vertical retention means to assure that said housing support member retains its position with respect to said base after a rocking tilt adjustment has been completed.
Claim 3
Dependent Claim
45 words
Apparatus as recited in claim 1 wherein said involute gear form includes a rack gear form on said base member coacting with a spur gear form on said housing support member, said gear forms being so constructed and arranged to allow for relative movement therebetween.
Claim 4
Dependent Claim
44 words
Apparatus as recited in claim 2 wherein said rocker means includes a flat rectangular member on said base member coacting with an arcuate rectangular member on said housing support member, said rectangular members being so constructed and arranged to allow for relative movement therebetween.
Claim 5
Dependent Claim
69 words
Apparatus as recited in claim 3 further including side retention means to assure alignment of coacting portions of the rocker means and the involute gear forms, said side retention means includes substantially parallel and vertical walls formed in said base member on each side of said flat rectangular member whereby said arcuate rectangular member is prevented from moving in a lateral direction with respect to said flat rectangular member.
