The present invention pertains to extension arm apparatuses that are adapted to support user devices throughout a range of positions. A given apparatus may include one or more arms that position the user device remotely from a support position. An extension and retraction device such as a gas cylinder is received within each arm, and provides a force to support the user device as the arm is placed into a given position. A variable force clevis is connected to the extension/retraction device within the arm. The variable force clevis is connected to a pair of locations in the arm as well. As the arm moves, for instance up or down, the variable force clevis rotates within the arm and dynamically adjusts the force provided by the extension/retraction device. Removable and/or pivotable covers are provided for managing cables of the user device attached to the extension arm.

The invention claimed is: 1. An adjustable support apparatus for supporting a user device, comprising: a first cap having a first section, a second section and a cover disposed between the first and second sections, the first section being adapted for engagement with a support surface and the cover being adapted for providing immediate access to a cable of the user device; a second cap having a first section, a second section and a cover disposed between the first and second sections, the first section being adapted for engagement with the user device and the cover being adapted for providing immediate access to the cable of the user device; a first arm member having first and second ends and a cover disposed between the first and second ends for providing immediate access to the user device cable, the first end of the first arm member being coupled to the second section of the first cap, and the first arm member being operable to receive an extension and retraction device therein for providing a force for supporting the user device; a middle cap disposed between the first and second caps, the middle cap having a first side, a second side and a cover coupled to the first and second sides thereof for providing access to the user device cable, the first side of the middle cap being connected to the second end of the first arm member; and a second arm member having first and second ends and a cover disposed between the first and second ends for providing immediate access to the user device cable, the first end of the second arm member being connected to the second side of the middle cap, the second end of the second arm member being connected to the second section of the second cap, and the second arm member being operable to receive a second extension and retraction device therein for providing a force for supporting the user device; wherein one of the first and second arm members including a variable force clevis connected to a respective one of the extension and retraction devices, the variable force clevis being operable to vary the force provided by the respective extension and retraction device as the respective one of the first and second arm members is adjusted between selected positions. 2. The adjustable support apparatus of claim 1, wherein the first arm member cover is removably coupled to the first arm member, the second arm member cover is removably coupled to the second arm member, and the middle cap cover is removably coupled to middle cap so that the cable of the user device is receivable within the first arm member, the second arm member and the middle cap. 3. The adjustable support apparatus of claim 2, wherein the first cap cover is pivotally connected to a surface of the first cap, the second cap cover is pivotally connected to a surface of the second cap, and the first and second cap covers are adapted to provide immediate access to the cable of the user device. 4. The adjustable support apparatus of claim 1, further comprising an extension member having first and second ends, the first end thereof being coupled to the first section of the second cap and the second end thereof being adapted for engagement with the user device. 5. The adjustable support apparatus of claim 4, wherein the extension member includes a cover disposed on a first surface thereof for providing immediate access to the cable of the user device. 6. The adjustable support apparatus of claim 5, wherein the cover is pivotally coupled to the first surface of the extension member. 7. The adjustable support apparatus of claim 1, wherein: the middle cap includes a first fastener disposed on the first side thereof and a second fastener disposed on the second side thereof, and a first side of the middle cap cover is removably connected to the first fastener and a second side of the middle cap cover is removably coupled to the second fastener; a first end of the first arm member cover is removably coupled to the first middle cap fastener; and a first end of the second arm member cover is removably coupled to the second middle cap fastener. 8. The adjustable support apparatus of claim 1, wherein: the first arm member includes an upper channel member and a lower channel member; the second arm member includes an upper channel member and a lower channel member; the first arm member cover is disposed along the upper channel member thereof; and the second arm member cover is disposed along the upper channel member thereof. 9. The adjustable support apparatus of claim 1, wherein the user device cable is substantially received within the first and second caps, the first and second arm members and the middle cap during use of the user device. 10. An adjustable support apparatus for supporting a user device, comprising; a first cap having a first section, the first section being adapted for engagement with a support surface, a second section and first cover means disposed between the first and second sections for providing immediate access to a cable of the user device; a second cap having a first section, the first section being adapted for engagement with the user device, a second section and second cover means disposed between the first and second sections for providing immediate access to the cable of the user device; a first arm member having first and second ends, the first end of the first arm member being coupled to the second section of the first cap, the first arm member being operable to receive an extension and retraction device therein for providing a force for supporting the user device, and third cover means disposed between the first and second ends for providing immediate access to the user device cable; a middle cap disposed between the first and second caps, the middle cap having a first side, a second side and fourth cover means coupled to the first and second sides thereof for providing access to the user device cable, the first side of the middle cap being connected to the second end of the first arm member, and a second arm member having first and second ends, the first end of the second arm member being connected to the second side of the middle cap, the second end of the second arm member being connected to the second section of the second cap. the second arm member being operable to receive a second extension and retraction device therein for providing a force for supporting the user device, and fifth cover means disposed between the first and second ends for providing immediate access to the user device cable; wherein one of the first and second arm members including variable force means connected to a respective one of the extension and retraction devices for varying the force provided by the respective extension and retraction device as the respective one of the first and second arm member is adjusted between selected positions.
