Abstract

A tilt control for a tiltable mount and a mount including a tilt control are provided. The mount has first and second brackets mounted for rotation or tilting, such as about a shaft. The second bracket might be a monitor mount tiltable relative to an arm bracket. The tilt control includes a friction brake and an over-running clutch configured to disengage the friction brake to permit upward rotation or tilting, but engage the friction brake for controlling the downward rotation or tilting. The friction brake is engaged by the over-running clutch to control downward tilting. The friction brake generates a counter-acting force to retain a mounted device such as a video monitor and/or keyboard in fixed position against drooping, but to permit downward tilting upon application by a user of an adjustment force.

Claims

1. An adjustable mount having a tilt control comprising:

a mount comprising;

a first bracket;

a second bracket; and

a shaft connecting said first bracket and said second bracket and permitting said brackets to be rotated relative to one another about an axis extending through said shaft in a tilt up direction and a tilt down direction; and

a tilt control associated with said mount, said tilt control comprising;

a friction brake configured to resist rotation of said first and second brackets relative to one another in a tilt down direction; and

a clutch mechanism associated with said shaft and configured to disengage said friction brake to permit said first and second brackets to rotate relative one another in said tilt up direction.

2. The adjustable mount in accordance with claim 1 wherein said first bracket comprises an arm mount.

3. The adjustable mount in accordance with claim 1 wherein said second bracket comprises a video monitor mount.

4. The adjustable mount in accordance with claim 1 wherein said clutch comprises an overrunning clutch mounted about said shaft.

5. The adjustable mount in accordance with claim 4 wherein said clutch is mounted between said shaft and said first bracket.

6. The adjustable mount in accordance with claim 1 wherein said friction brake comprises at least one friction element engaging at least a portion of said second bracket.

7. The adjustable mount in accordance with claim 6 wherein said second bracket comprises one or more brake plates and said at least one friction element engages one of said brake plates.

8. The adjustable mount in accordance with claim 1 wherein said friction brake is mounted to said shaft.

9. The adjustable mount in accordance with claim 1 wherein said friction brake comprises a plurality of friction washers.

10. The adjustable mount in accordance with claim 1 wherein said friction brake comprises means for adjusting a friction braking force generated by said friction brake.

11. The adjustable mount in accordance with claim 10 wherein said means for adjusting comprises at least one spring configured to generate a compressive force against a braking member of said friction brake.

12. The adjustable mount in accordance with claim 11 further comprising at least one adjusting screw configured to selectively compress said at least one spring.
