Abstract

Abstract A computer monitor is provided with a chassis including a base, a rear support fixed to the base and extending vertically upwardly therefrom, and a front support connected to a cathode-ray tube. The front support and the cathode-ray tube are mounted above the base and spaced apart therefrom for pivotal movement of the front support and cathode-ray tube relative to the base and rear support about a pivot axis disposed at the upper front portion of the monitor. The monitor can be releasably maintained in any one of a plurality of angular positions. The monitor housing comprises a first section surrounding the base and rear support and a second section completely detached from the first section and surrounding the front support.

Claims Analysis

Total Claims: 5
Claim 1
Independent Claim 322 words
In a computer monitor having a cathode-ray tube with a display face, a chassis mounting the cathode-ray tube with the display face at the front of the monitor and a housing surrounding the chassis, the improvement wherein the chassis comprises a front chassis section having a front portion corresponding to the front of the monitor and a rear portion and to which the cathode-ray tube is secured to dispose the display face at the front portion, a rear chassis section behind the front section, a base disposed below the front and rear chassis sections and secured to the rear chassis section, means connecting the front chassis section to the rear chassis section and spaced above the base for free pivotable movement of the front chassis section relative to the base and rear chassis section about a pivot axis disposed at the upper front portion of the front chassis section, and manually actuatable means movable between a rest position, wherein the front chassis section is releasably retained in a desired pivot position, and a actuated position, wherein the front chassis is free to pivot around its pivot axis, wherein the manually actuatable means comprises a handle, means mounting the handle on one side of the front chassis section at the rear portion thereof for sliding movement towards the front portion of the front chassis section to move the manually actuatable means into the actuated position, a first locking member fixed to the rear chasis section, a second locking member and means mounting the second locking member on the front chassis section for sliding movement in a direction perpendicular to the movement of the handle and in response to the movement of the handle towards the front portion of the front chassis section from a first position, wherein the second locking member engages the first locking member, to a second position, wherein the second locking member is spaced apart from the first locking member.
Claim 2
Dependent Claim 322 words
In a computer monitor having a cathode-ray tube with a display face, a chassis mounting the cathode-ray tube with the display face at the front of the monitor and a housing surrounding the chassis, the improvement wherein the chassis comprises a front chassis section having a front portion corresponding to the front of the monitor and a rear portion and to which the cathode-ray tube is secured to dispose the display face at the front portion, a rear chassis section behind the front section, a base disposed below the front and rear chassis sections and secured to the rear chassis section, means connecting the front chassis section to the rear chassis section and spaced above the base for free pivotable movement of the front chassis section relative to the base and rear chassis section about a pivot axis disposed at the upper front portion of the front chassis section, and manually actuatable means movable between a rest position, wherein the front chassis section is releasably retained in a desired pivot position, and a actuated position, wherein the front chassis is free to pivot around its pivot axis, wherein the manually actuatable means comprises a handle, means mounting the handle on one side of the front chassis section at the rear portion thereof for sliding movement towards the front portion of the front chassis section to move the manually actuatable means into the actuated position, a first locking member fixed to the rear chasis section, a second locking member and means mounting the second locking member on the front chassis section for sliding movement in a direction perpendicular to the movement of the handle and in response to the movement of the handle towards the front portion of the front chassis section from a first position, wherein the second locking member engages the first locking member, to a second position, wherein the second locking member is spaced apart from the first locking member.
Claim 3
Dependent Claim 21 words
The computer monitor according to claim 1, wherein the handle is disposed at the upper portion of the front chassis section.
Claim 4
Dependent Claim 66 words
The monitor according to claim 1, wherein the connecting means comprises two aligned pivot pins on sides of the rear chassis section and forming said pivot axis, a bushing on sides of the front chassis section receiving the pivot pin, and wherein the first locking member comprises a first toothed member, the second locking member comprises a second toothed member engageable with the first toothed member.
Claim 5
Dependent Claim 36 words
The monitor according to claim 1, wherein teeth of the second toothed member are disposed along an arcuate path to engage teeth of the first toothed member in any on of a plurality of relative positions.
