Tilt control for tiltable mount
First Claim
1. An adjustable mount comprising:
- a mount comprising;
a first bracket;
a second bracket; and
a shaft coupled between said first bracket and said second bracket, said shaft configured to permit said brackets to be rotated relative to one another about 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 coupled between said first and second brackets, said friction brake configured to resist rotation of said first and second brackets relative to one another; and
a clutch mechanism coupled between said first bracket and said friction brake, said clutch mechanism comprising an overrunning clutch mounted about said shaft, said clutch mechanism configured to permit rotation of said first bracket relative to said friction brake in said tilt up direction and to resist rotation of said first bracket relative to said friction brake in said tilt down direction.

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.

12. An adjustment mechanism comprising:
-
a first bracket; a clutch means comprising a first part and a second part, said first part coupled to said first bracket, said clutch means configured to permit rotation of said second part relative to said first part in a first direction but not in a second direction that is opposite to said first direction; a friction means comprising a third part and a fourth part, said third part coupled to said second part of said clutch means, said friction means configured to adjustably resist rotation of said third part relative to said fourth part; and a second bracket coupled to said fourth part of said friction means wherein; said clutch means and said friction means are arranged about a common axis; said second part rotates about said common axis relative to said first part; said fourth part rotates about said common axis relative to said third part; said friction means can be adjusted to provide a first amount of resistance to rotation of said fourth part relative to said third part within a range; and said clutch means permits rotation of said second part with respect said first part with a second amount of resistance that is less than said range of said first amount of resistance of said friction means. - View Dependent Claims (13)
