Video arm assembly
A video arm assembly includes a base attachable to a surface, a knuckle rotatably engaging the base, and an arm connected to the knuckle. A friction clutch is connected to the base. A one-way bearing engages the friction clutch and the knuckle, providing rotation of the knuckle with respect to the base in a first direction only. The friction clutch engages the one-way bearing such that the knuckle rotates with respect to the base in a second direction opposite the first direction, the one-way bearing rotating with the knuckle in the second direction, and the arm rotating with the knuckle in the first and second directions.
1. A video arm assembly, comprising: a base directly attachable to a surface; a knuckle rotatably engaging the base, wherein the knuckle includes a spindle, and wherein a portion of the knuckle is disposed within the base; an arm connected to the knuckle so as to rotate with the knuckle; a friction clutch disposed within the base; a one-way bearing engaging the friction clutch and the spindle, providing rotation of the knuckle with respect to the one-way bearing and the base in a first direction, and wherein the one-way bearing is disposed between the spindle and the friction clutch; wherein the friction clutch engages the one-way bearing so that when the knuckle rotates with respect to the base in a second direction opposite the first direction, the one-way bearing rotates with the knuckle in the second direction.
2. The video arm assembly of claim 1 , further comprising a mount engaging the arm opposite the knuckle.
3. The video arm assembly of claim 2 , wherein the mount is rotatable relative to the arm.
4. The video arm assembly of claim 2 , in combination with a video monitor, wherein the video monitor is rotatable relative to the arm when supported by the mount.
5. The video arm assembly of claim 1 , wherein the arm is rotatable relative to the knuckle.
6. The video arm assembly of claim 1 , wherein the base includes a track, the knuckle engages the track, and the track limits rotation of the knuckle.
7. The video arm assembly of claim 6 , wherein the knuckle includes rollers engaging the track.
8. The video arm assembly of claim 1 , wherein the base limits rotation of the arm.
9. The video arm assembly of claim 1 , further comprising a stop; and a latch removably engaging the stop wherein the latch prevents movement of the knuckle in the first direction when the latch engages the stop.
10. The video arm assembly of claim 1 , wherein the friction clutch comprises an adjustable friction clutch.
11. A video arm assembly, comprising: a base directly attachable to a surface; a knuckle rotatably engaging the base, wherein the knuckle includes a spindle, and wherein a portion of the knuckle is disposed within the base; an arm connected to the knuckle to rotate with the knuckle; a mount engaging the arm opposite the knuckle; a friction clutch disposed within the base; a one-way bearing engaging the friction clutch and the spindle, providing rotation of the knuckle with respect to the one-way bearing and the base in a first direction, and wherein the one-way bearing is disposed between the spindle and the friction clutch; a stop connected to the knuckle; a latch removably engaging the stop wherein the latch prevents movement of the knuckle in the first direction when the latch engages the stop; wherein the friction clutch engages the one-way bearing such that when the knuckle rotates with respect to the base in a second direction opposite the first direction, the one-way bearing rotates with the knuckle in the second direction.
12. The video arm assembly of claim 11 , wherein the mount is rotatable relative to the arm.
13. The video arm assembly of claim 11 , in combination with a video monitor, wherein the video monitor is rotatable relative to the arm when supported by the mount.
14. The video arm assembly of claim 11 , wherein the arm is rotatable relative to the knuckle.
15. The video arm assembly of claim 11 , wherein the base includes a track, the knuckle engages the track, and the track limits rotation of the knuckle.
16. The video arm assembly of claim 15 , wherein the knuckle includes rollers engaging the track.
17. The video arm assembly of claim 11 , wherein the base limits rotation of the arm.
18. The video arm assembly of claim 11 , wherein the friction clutch comprises an adjustable friction clutch.
19. A video arm assembly, comprising: a base directly attachable to a surface; a knuckle rotatably engaging the base, wherein a portion of the knuckle is disposed within the base; an arm connected to the knuckle so that the arm rotates with the knuckle; a mount engaging the arm opposite the knuckle for supporting a video monitor, wherein the mount is rotatable relative to the arm; an adjustable friction clutch disposed within the base; a one-way bearing engaging the friction clutch and the knuckle, providing rotation of the knuckle with respect to the one-way bearing and the base in a first direction, wherein the knuckle includes a spindle engaging the one-way bearing, and wherein the one-way bearing is disposed between the spindle and the friction clutch; a stop connected to the knuckle; a latch removably engaging the stop wherein the latch prevents movement of the knuckle in the first direction when the latch engages the stop; wherein the friction clutch engages the one-way bearing whereby when the knuckle rotates with respect to the base in a second direction opposite the first direction, the one-way bearing rotates with the knuckle in the second direction, and wherein the base includes a track, the knuckle includes rollers engaging the track, and the track limits rotation of the knuckle.
