Abstract
In a video unit 1, the video screen 2 is pivoted so that the angle of the screen can be adjusted as desired, relative to the unit housing 4. The screen 2 is preferably encircled by a steel band 7 forming part of a frame 9 including brackets 8 and upright frame members 10. The frame members 10 are pivoted about a horizontal axis through pivots 16 in a fixed framework 15. The arrangement permits an optimum viewing angle to be chosen by the viewers. <IMAGE>
Description
SPECIFICATION
A video unit
This invention relates to a video unit comprising a video screen mounted in a cabinet so that the video screen can be viewed through an aperture in the cabinet.
In known video units of this type, the video screen is invariably fixed in the cabinet so that the angle of the screen cannot change, with the result that the angle is less than optimum for at least some people.
According to the invention there is provided a video unit comprising a video screen mounted in a cabinet so that the video screen can be viewed through an aperture in the cabinet, characterised in that the video screen is mounted movably in the cabinet in such a manner that the angle of the video screen relative to the cabinet aperture is adjustably variable.
The invention will be described by way of example with reference to the accompanying drawings, wherein Figure lisa front elevation of a video unit embodying the invention, the left hand half of the
Figure showing an outer frame and an inner frame both removed to illustrate the mounting of the video screen;
Figure 2 is a side elevation of the video unit of
Figure 1, with the front of the unit cut away and sectioned to illustrate the mounting of the video screen; and
Figure 3 is a partial section on iine Ill-Ill of Figure 1.
Referring to the drawings, the illustrated video unit 1 comprises a video screen 2 mounted in a cabinet 3 so that the video screen 2 can be viewed through an aperture 4 in the cabinet 3. The video screen 2 is mounted pivotably in the cabinet 3 in such a manner that the angle of the video screen 2 relative to the cabinet aperture 4 is adjustably variable, in that the video screen 2 is pivotable about a horizontal axis 5.
The video screen 2 is the screen of a cathode ray tube 6 and is mounted in the cabinet 3 by means, inter alia of a spring steel band 7 which tightly encircles the video screen 2 and to which are joined four brackets 8 respectively at the four corners of the screen 2. The spring steel band 7 and the four brackets 8 form part of a framework 9 which also includes two generally upright frame members 10, to which the brackets 8 are connected by four mountings 11 each comprising a bolt 12, a nut 13 and a spacerwasher 14. The two frame members 10 are pivoted (to pivot about the horizontal axis 5) to a fixed framework 15 inside the cabinet 3 by means of two respective pivots 16, each similarly consisting of a bolt 17, nut 18 and spacer washer 19.The mounting of the tube 6 in the framework 9 is such that the combination of the tube 6 and the framework 9 is movable as one unit in the cabinet 3.
An inner frame 20 is mounted to the frame members 10 by means offourscrews 21 (two such screws 21 being shown in the left hand half of Figure 1) so that the video screen 2 and inner frame 20 are movable as one unit together with the framework 9.
The cabinet 3 comprises a fixed outer frame 22 at the front thereof. In Figure 1, the inner frame 20 and outer frame 22 are shown cut away or removed in the left hand half of the Figure.
The horizontal axis 5 passes through, or nearly through, the centre of gravity of the combination of the cathode ray tube 6, framework 9 and inner frame 20, so that the angle of the video screen 2 has little or no tendency to change once adjusted.
The illustrated video unit 1 may for example be a video monitor for use as part of a computer system.
In a modification, not shown, the video screen may be adapted to be pivotable not only about a horizontal axis such as the axis 5, but aiso about a vertical axis, so that the angle of the video screen 2 can be adjusted in azimuth as well as in elevation.
It is desirable for the pivots 16 to have some friction in them, in order for the angle of the video screen 2 not to change unintentionally.
1. A video unit comprising a video screen mounted in a cabinet so that the video screen can be viewed through an aperture in the cabinet, characterised in that the video screen is mounted movably in the cabinet in such a manner that the angle of the video screen relative to the cabinet aperture is adjustably variable.
2. A video unit as claimed in Claim 1 wherein the movability of the video screen is a pivotability about a horizontal axis.
3. A video unit as claimed in Claim 1 or 2 wherein the video screen is the screen of a cathode ray tube.
4. A video unit as claimed in Claim 3 as dependent from Claim 2 wherein the axis passes through or nearly through the centre of gravity of a movable mass of which the tube forms at least part.
5. A video unit as claimed in Claim 3 or 4 wherein the tube is mounted in or to a framework or to frame members so that the combination of the tube and the framework or frame members is movable as one unit in the cabinet, the tube being mounted by means of the framework or frame members in the cabinet.
6. A video unit as claimed in Claim 5 wherein a metal band tightly encircles the screen, brackets joined to the band being used to mount the tube in or to the framework or frame members.
7. A video unit as claimed in any preceding claim wherein an inner frame frames the video screen and is movable as one therewith.
