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 ### 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. ### Claim 2 (depends on 1) The adjustable mount of claim 1, wherein said first bracket comprises an arm mount. ### Claim 3 (depends on 1) The adjustable mount of claim 1, wherein said second bracket comprises a video monitor mount. ### Claim 4 (depends on 1) The adjustable mount of claim 1, wherein said clutch mechanism is coupled between said shaft and said first bracket and said friction brake is coupled between said shaft and said second bracket. ### Claim 5 (depends on 4) The adjustable mount of claim 4, wherein said friction brake comprises at least one friction element engaging at least a portion of said second bracket. ### Claim 6 (depends on 5) The adjustable mount of claim 5, wherein said second bracket comprises one or more brake plates and said at least one friction element engages at least one of said brake plates. ### Claim 7 (depends on 1) The adjustable mount of claim 1, wherein said friction brake is mounted to said shaft. ### Claim 8 (depends on 1) The adjustable mount of claim 1, wherein said friction brake comprises a plurality of friction washers. ### Claim 9 (depends on 1) The adjustable mount of claim 1, wherein said friction brake comprises means for adjusting a friction braking force generated by said friction brake. ### Claim 10 (depends on 9) The adjustable mount of claim 9, wherein said means for adjusting comprises at least one spring configured to generate a compressive force against a braking member of said friction brake. ### Claim 11 (depends on 10) The adjustable mount of claim 10, further comprising at least one adjusting screw configured to selectively compress said at least one spring. ### Claim 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. ### Claim 13 (depends on 12) The adjustment mechanism of claim 12, wherein: when said second bracket is urged to rotate in said first direction relative to said first bracket, said second part rotates with respect to said first part and said fourth part remains stationary with respect to said third part; and when said second bracket is urged to rotate in said second direction relative to said first bracket, said second part remains stationary with respect to said first part and said fourth part rotates with respect to said third part.
