Arm assembly
A workstation holding electronic devices, e.g., a display, keyboard, or the like, can be mounted on a structure, e.g., a wall, using an articulating arm assembly including one or more arms. The one or more arms can be rotatingly coupled to the structure. The one or more arms can be configured to translate the workstation between a contracted orientation and extended orientation. The arm assembly can include a configurable rotation stop assembly. The rotation stop assembly can be configured to limit a rotation angle of the one or more arms in a range between 0 degrees in the contracted orientation and less than 180 degrees in the extended orientation.

11 . The articulating arm assembly of claim 10 , wherein the first edge is adapted to cooperate with the first stop surface to stop the rotation of the second arm relative to the first arm in the stowed orientation, and wherein the second edge is adapted to cooperate with the second stop surface to stop the rotation of the second arm relative to the first arm in the extended orientation.
12 . An articulating arm assembly,
the arm assembly comprising:
