US Patent 11397450 Tablet support arm structures

Structures and systems are disclosed for supporting tablets or displays. A core arm that is configured to have a range of rotation based on angle length of a track or tunnel, an angle length of a joint rotation stop structure, and an angle length of a floating stop key. The core extends from a rear end to a front end of the structure. The core arm can also include a floating stop key that is movable with the track or tunnel of the core arm structure. The structures and systems can thus be readily configured for light or heavy configurations, with or without the use of an extension arm, and can conceal cable routing, which is accessible, via snap fit covers, for easy installation and maintenance.
