Abstract

An extension arm has an inner end mounted to a base plate for rotation about a first vertical axis, and an outer end supporting a head assembly. The head assembly has a lower disc fixed to the arm and an upper disc mounted to the lower disc for rotation about a second vertical axis. A first clevis is secured to the upper disc, and includes a first clevis pin passing through the lower end of a connection arm about a first horizontal axis. Adjustable locking means are provided in the first clevis pin, to interlock the first clevis with the connection arm in a selected rotational position about the first horizontal axis. The upper end of the connection arm is secured to a second clevis with a second clevis pin about a second horizontal axis. The second clevis is mounted to a monitor plate which supports the video monitor.

Claims

1. An adjustable support arm for a video monitor, comprising:

a. a base plate;

b. an extension arm having an inner end and an outer end, said inner end being mounted to said base plate for rotation about a first vertical axis;

c. a head assembly having a lower disc fixed to said outer end of said extension arm and an upper disc mounted to said lower disc for rotation about a second vertical axis;

d. a first clevis secured to said upper disc, said first clevis including a first clevis pin;

e. a connection arm having a lower end and an upper end, said first clevis pin passing through a bore in said lower end about a first horizontal axis.

f. adjustable locking means in the first clevis pin, to interlock the first clevis with the connection arm in a selected rotational position about said first horizontal axis;

g. a video monitor plate; and

,

h. a second clevis secured to said video mounting plate, said second clevis including a second clevis pin passing through said upper end of said connection arm about a second horizontal axis.

2. An apparatus as in claim 1 including a keyboard plate, said keyboard plate being pivotally attached to an underside of said lower disc about a third horizontal axis.

3. An apparatus as in claim 1 in which said first clevis includes a first side plate and a second side plate and in which said adjustable locking means comprises splines on one end of said first clevis pin, and a spline receiver in said second side plate.

4. An apparatus as in claim 3 in which a clevis pin tube is provided in said bore of said lower end of said connection arm, said clevis pin tube including tube key to engage a connection arm keyway.

5. An apparatus as in claim 4 in which said first clevis pin slidably translates within said clevis pin tube, and in which said first clevis pin includes a pin key to engage a second side plate keyway.

6. An apparatus as in claim 5 further including resilient bias means to urge said splines of said first clevis pin into engagement with said spline receiver.

7. An apparatus as in claim 6 in which said resilient bias means comprises a spring in coaxial relation with said first clevis pin.

8. An apparatus as in claim 1 in which said video monitor plate is planar and includes means for direct attachment to a flat screen video monitor.

9. An apparatus as in claim 8 in which a loudspeaker is attached to an upper end of said video monitor plate.

10. An adjustable support arm for a video monitor, comprising:

a. a base plate;

b. an extension arm having an inner end and an outer end, said inner end being mounted to said base plate for rotation about a first vertical axis;

c. a head assembly having a lower disc fixed to said outer end of said extension arm and an upper disc mounted to said lower disc for rotation about a second vertical axis;

d. a connection arm having a lower end and an upper end;

e. first means for rotatably attaching said lower end of said connection arm to said upper disc about a first horizontal axis, and for selectively locking said connection arm in a selected rotational position;

f. a video monitor plate; and

,

g. second means for rotatably attaching said upper end of said connection arm to said video monitor plate about a second horizontal axis.

11. An apparatus as in claim 10 in which said base plate is mounted to an arm of a chair.

12. An apparatus as in claim 10 including a keyboard plate, said keyboard plate being pivotally attached to an underside of said lower disc.

13. An apparatus as in claim 10 in which said first means for rotatably attaching said lower end of said connection arm to said upper disc comprises a first clevis and a first clevis pin.

14. An apparatus as in claim 13 in which said means for selectively locking said connection arm in a selected rotational position comprises splines on one end of said first clevis pin, and a spline receiver in a side plate of said first clevis.

15. An apparatus as in claim 14 further including resilient bias means to urge said splines of said first clevis pin into engagement with said spline receiver.

16. An apparatus as in claim 10 in which said video monitor plate is planar and includes means for direct attachment to a flat screen video monitor.

17. An apparatus as in claim 10 in which said second means for rotatably attaching said upper end of said connection arm to said video monitor plate comprises a second clevis and a second clevis pin.

18. An adjustable support arm for a video monitor, comprising:

a. a base plate;

b. an extension arm having an inner end and an outer end, said inner end being mounted to said base plate for rotation about a first vertical axis;

c. a head assembly having a lower disc fixed to said outer end of said extension arm and an upper disc mounted to said lower disc for rotation about a second vertical axis;

d. a first clevis secured to said upper disc, said first clevis including a first clevis pin;

e. a connection arm having a lower end and an upper end, said first clevis pin passing through said lower end about a first horizontal axis.

f. adjustable locking means in the first clevis pin, to interlock the first clevis with the connection arm in a selected rotational position about said first horizontal axis;

g. a video monitor plate; and

,

h. a flange on said upper end of said connection arm for attachment to said video monitor plate.

19. An apparatus as in claim 18 in which said video monitor plate includes an upper planar surface for the support of a CRT video monitor.

20. An apparatus as in claim 19 including a keyboard plate, said keyboard plate being pivotally attached to an underside of said lower disc.
