Abstract
Abstract An apparatus for permitting, and limiting the extent of, tilting and rotating of a display monitor. The apparatus is made up of a top portion and a bottom portion. The top and bottom portions are connectable though a key and lock arrangement and have spherical mating contoured surfaces. The mating contoured surfaces permit the tilting and rotating of the monitor. Located on the bottom portion is a projection for engaging the top portion and limiting the extent of rotation of the monitor. The key and lock arrangement includes a lock in the bottom portion for cooperating with a key on the top portion to control the extent of tilting of the monitor. In addition, the top portion has outwardly and downwardly extending wings for limiting vibration of the monitor.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
203 words
An apparatus for permitting, and limiting the extent of, tilting and rotating of a display monitor, said apparatus comprising in combination: (a) a top portion having a spherically contoured surface, a key means extending from said surface, and wings (1) adjacent said surface, (2) extending outwardly and downwardly from said surface a sufficient extent to limit vibration of said monitor, and (3) having bottom surfaces which are arcuate in shape and have a curvature matching that of said contoured surface of said top portion; and (b) a bottom portion having (1) a contoured surface for mating with said contoured surface of said top portion and having an annular lip, (2) a lock adapted to be engaged by said key for limiting the extent of tilting of said monitor, (3) means extending from said bottom portion for engaging said top portion and limiting the extent of rotation of said monitor, and (4) a plate extending circumferentially from said annular lip, and being of a sufficient size to be contacted by said arcuate shaped bottom surfaces during tilting and rotating of said monitor to limit vibration of said monitor for the extent of rotation of said monitor when said top and bottom portions are connected.
Claim 2
Independent Claim
203 words
An apparatus for permitting, and limiting the extent of, tilting and rotating of a display monitor, said apparatus comprising in combination: (a) a top portion having a spherically contoured surface, a key means extending from said surface, and wings (1) adjacent said surface, (2) extending outwardly and downwardly from said surface a sufficient extent to limit vibration of said monitor, and (3) having bottom surfaces which are arcuate in shape and have a curvature matching that of said contoured surface of said top portion; and (b) a bottom portion having (1) a contoured surface for mating with said contoured surface of said top portion and having an annular lip, (2) a lock adapted to be engaged by said key for limiting the extent of tilting of said monitor, (3) means extending from said bottom portion for engaging said top portion and limiting the extent of rotation of said monitor, and (4) a plate extending circumferentially from said annular lip, and being of a sufficient size to be contacted by said arcuate shaped bottom surfaces during tilting and rotating of said monitor to limit vibration of said monitor for the extent of rotation of said monitor when said top and bottom portions are connected.
Claim 3
Dependent Claim
