Abstract

A tilt stand designed for use with a cathode ray display provides infinite angular positioning up to 45 degrees from the horizontal. The tilt stand may be placed upon a desk or mounted under a shelf. Infinite positioning is provided by friction between spring-loaded hub sections against the periphery of a hub cavity. The figure shows a cradle base 11 having a hub cavity 13 at each end. Hub sections 15 fit into hub recess 13 and are pushed outward against the periphery of hub recess 13 by a spring 17. Hub sections 15 are molded to provide clearance between them for pins 19 of tilt bracket 21. Hub cavity 13 depth and hub section 15 thickness determine the clearance for the tilt bracket 21 within the cradle base 11.

Friction Hub for Tilt Stand

A tilt stand designed for use with a cathode ray display provides infinite angular positioning up to 45 degrees from the horizontal. The tilt stand may be placed upon a desk or mounted under a shelf. Infinite positioning is provided by friction between spring-loaded hub sections against the periphery of a hub cavity.

The figure shows a cradle base 11 having a hub cavity 13 at each end. Hub sections 15 fit into hub recess 13 and are pushed outward against the periphery of hub recess 13 by a spring 17. Hub sections 15 are molded to provide clearance between them for pins 19 of tilt bracket 21. Hub cavity 13 depth and hub section 15 thickness determine the clearance for the tilt bracket 21 within the cradle base 11.

Assembly is accomplished by compressing spring 17 between hub sections 15 by hand and inserting into recess 13 at each vertical support of base 11. The tilt bracket is then flexed to permit pins 19 to clear the cradle sides for positioning between hub sections 15 at each end. Although tilt brackat 21 can be rotated with controlled friction force through 360 degrees, the practical amount of adjustment is approximately 30 degrees from the horizontal whether base 11 is positioned on a table top or mounted under a shelf.

The mechanism is completely concealed. and requires no assembly tools and no adjustment at or after assembly.
