Abstract: 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. Thus, the arm may be positioned as desired, as such force adjustment stabilizes the arm.

Abstract: The present invention provides a device for holding a laptop computer or other portable devices. The laptop is placed on a support having a generally planar surface. A pair of adjustable arm members is pivotally connected to the support. The user may adjust one or both of the arm members to accommodate portable devices of different sizes. Clips or other connectors are used to secure the laptop to the holding device. The clips connect to the arm members and to the support. The clips may have one or more components, and may be configured to slide along the arm members and the support. The support may include a number of projections that can be arranged in an X-shaped configuration. A release plate or other connector couples the holding device to an extension assembly. The release plate provides a quick release from a tilting device of the extension assembly.
