The present invention provides an extension arm apparatus with angled clevis operation to provide enhanced mechanical leverage. The clevis adjusts along a path angled relative to an axis of the device, which significantly boosts performance and can reduce the size of the apparatus. Upper and lower channels of the device taper from a first width to a second width, providing a sleek and functional apparatus that can be used with heavy monitors, displays or other user equipment. When a forearm extension attached to an endcap of the apparatus, an interlocking washer and shaft configuration prevents the forearm extension-endcap connection from loosening during operation.

The invention claimed is: 1. An extension arm apparatus for supporting a user device, the apparatus comprising: a first endcap having a first section for connection to a mount and a second section connected to the first section thereof; a second endcap having first and second sections, the second section of the second endcap including a receptacle having an opening therein; a first channel having first and second ends, the first end of the first channel being connected to the second section of the first endcap, and the second end of the first channel being connected to the first section of the second endcap; a second channel having first and second ends, the first end of the second channel being connected to the second section of the first endcap, and the second end of the second channel being connected to the first section of the second endcap, the first and second channels defining a receptacle for a spring device; and a forearm assembly including an anti-loosening apparatus and a forearm extension having a first end operatively coupled to the second section of the second endcap and a second end for supporting the user device, the first end of the forearm extension including a shaft and at least one recess disposed in the shaft, the shaft being at least partly received within the opening in the second section of the second endcap, the anti-loosening apparatus comprising a washer and a fastener, the washer having at least one protrusion adapted to be received within the at least one recess to connect the washer to the shaft, and the fastener securing the second section of the second endcap, the washer and the shaft together so that the shaft is rotatable relative to the second section of the second endcap; wherein the anti-loosening apparatus permits rotation of the forearm extension relative to the second endcap while preventing loosening between the forearm extension and the second endcap during rotation. 2. The extension arm apparatus of claim 1, wherein the fastener is threadedly secured to the shaft, and the connection between the washer and the shaft prevents the fastener from loosening during movement of the forearm extension. 3. The extension arm apparatus of claim 1, wherein the forearm assembly further comprising a bushing positioned in the opening of the receptacle to at least partly surround the shaft. 4. The extension arm apparatus of claim 1, wherein the forearm assembly further comprises an outer washer disposed between an exterior surface of the forearm extension and an exterior surface of the receptacle. 5. The extension arm apparatus of claim 1, wherein the at least one recess comprises a pair of recesses disposed along an outer surface of the shaft, and the at least one protrusion of the washer comprises a pair of protrusions adapted to be received within the pair of recesses. 6. The extension arm apparatus of claim 1, wherein: the first channel tapers from a first width at the first end thereof to a second width at the second end thereof; the second channel tapers from a third width at the first end thereof to a fourth width at the second end thereof; and the forearm extension tapers from a fifth width at a first end adjacent to the second endcap to a sixth width at a second end remote from the second endcap. 7. The extension arm apparatus of claim 6, wherein the third width is substantially equal to the first width and the fourth width is substantially equal to the second width. 8. An extension arm apparatus for supporting a user device, the apparatus comprising: a first endcap having means for mounting to a surface; a second endcap; an first channel having first and second ends, the first end of the first channel being connected to the first endcap, and the second end of the first channel being connected to the second endcap; a second channel having first and second ends, the first end of the second channel being connected to the first endcap, and the second end of the second channel being connected to the second endcap; a forearm extension having first and second ends, the first end of the forearm extension being operatively coupled to the second endcap and the second end of the forearm extension being operatively coupled to the user device; and means for preventing loosening between the forearm extension and the second endcap. 9. An extension arm apparatus for positioning a user device, comprising: a first housing for securing the extension arm apparatus to a support; a second housing remote from the first housing, the second housing including a receptacle therein; a channel assembly connecting the first and second housings, the channel assembly being adjustable to change positioning of the extension arm apparatus; a supporting device connectable to the user device, the supporting device including a first connecting member on a surface thereof; and a connection assembly for connecting the supporting device to the second housing, the connection assembly including a washer and a fastener, the washer having an opening therethrough and a second connecting member on a first surface thereof, the second connecting member securing to the first connecting member of the supporting device, and the fastener being insertable through the opening of the washer and the receptacle of the second housing to threadedly engage the supporting device; wherein the supporting device is rotatable about the second housing and the first and second connecting members prevent loosening of the supporting device relative to the second housing. 10. The extension arm apparatus of claim 9, wherein the supporting device includes a shaft having the first connecting member, the receptacle of the second housing includes a lip, and the extension arm apparatus further comprises a bushing disposed around the shaft, the bushing being retained within the receptacle of the second housing between the lip and the washer. 11. The extension arm apparatus of claim 9, wherein the supporting device comprises a forearm extension. 12. The extension arm apparatus of claim 9, wherein the supporting device comprises a tilting device.
