Abstract

This adjustability system provides rotation of the CRT display up to 150Œ. Any place during that rotation, the CRT display may be tilted from -5Œ to +15Œ. This system is essentially made up of - a base 10 which rests on the work surface - an upper unit 11 which can attach to the CRT display by means of attachments tabs 9, and - a rotation disc 7. Base 10 has the following key items: rotation slots 1 and rotation guide surface 6. Rotation slots 1 provide the rotation. Mounting studs 2 of rotation disc 7 are inserted into rotation slots 1 which are a part of the base 10. Mounting studs 2 are designed so that they compress to allow insertion into slots 1, and then expand so that rotation disc 7 becomes firmly attached to base 10.

CRT Display Adjustability System

This adjustability system provides rotation of the CRT display up to 150OE. Any place during that rotation, the CRT display may be tilted from -5OE to +15OE. This system is essentially made up of - a base 10 which rests on the work surface - an upper unit 11 which can attach to the CRT display by means of attachments tabs 9, and - a rotation disc 7. Base 10 has the following key items: rotation slots 1 and rotation guide surface 6. Rotation slots 1 provide the rotation. Mounting studs 2 of rotation disc 7 are inserted into rotation slots 1 which are a part of the base 10. Mounting studs 2 are designed so that they compress to allow insertion into slots 1, and then expand so that rotation disc 7 becomes firmly attached to base 10. Upper unit 11 attaches to the rotation disc 7 by means of stud 5 which is inserted into rotation disc opening 3. Slot 4 provides tilt control. When the unit is assembled, stop 8 will engage surface 12 before stud 5 is allowed to enter opening 3. Rotation guide surface 6 provides a load-bearing surface for upper unit 11 rotation surface 13. This complete unit is held together without fasteners, allowing for fast, low-cost assembly. The main advantages of this system over existing designs are: - low cost parts - increased rotation; this design provides approximately 110 more display position during rotation. The addition of rotation disc 7 allows the CRT unit to remain in its preselected tilted position dur...
