Abstract

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.

First claim

The claimed invention is:

1 . An articulating arm assembly, the arm assembly comprising:
a structure interface; a first arm rotatingly coupled to the structure interface; a second arm rotatingly coupled to the first arm at a first hinge, wherein the second arm is configured to rotate relative to the first arm between a stowed orientation and an extended orientation; a mount assembly rotatingly coupled to the second arm; wherein the mount assembly is adapted to be coupled to one or more electronic devices; and a rotation stop assembly disposed at least partially within the first hinge and configured to limit a rotation angle between the first arm and the second arm in a range between 0 degrees in the stowed orientation and less than 180 degrees in the extended orientation, the rotation stop assembly also configured to:
permit clockwise rotation and limit counterclockwise rotation of the second arm relative to the first arm when the first arm rotates counterclockwise relative to the structure interface; and
permit counterclockwise rotation and limit clockwise rotation of the second arm relative to the first arm when the first arm rotates counterclockwise relative to the structure interface.

2 . The articulating arm assembly of claim 1 , wherein the second arm is configured to overlap with the first arm in the stowed orientation, and wherein the second arm is configured to rotate away from the first arm in the extended orientation.

3 . The articulating arm assembly of claim 1 , wherein the structure interface is a wall mount.

4 . The articulating arm assembly of claim 1 , wherein the first arm is one of an extension arm or a height adjustable arm, and wherein the second arm is one of an extension arm or a height adjustable arm.

5 . The articulating arm assembly of claim 1 , wherein the arm assembly further comprising a rotation stop ring, and wherein the rotation stop ring is coupled to the first arm.

6 . The articulating arm assembly of claim 5 , wherein the rotation stop ring includes:
a first aperture; a second aperture; a first stop surface proximate the first aperture; and a second stop surface proximate the second aperture.

7 . The articulating arm assembly of claim 6 , wherein the rotation stop assembly further comprises:
a knob; a nut; a plunger having a first end and a second end coupled to the knob, wherein the plunger at least partially located inside the nut; and a spring coupled to the nut and to the plunger; wherein the plunger is configured to translate relative to the nut between a first position and a second position, wherein the first end is away from the nut in the first position and the first end is proximate the nut in the second position; and wherein the spring is adapted to bias the plunger towards the first position.

8 . The articulating arm assembly of claim 7 , wherein the second arm includes a boss comprising:
a first edge; and a second edge; wherein the boss, the first edge, and the second edge rotate with the second arm.

9 . The articulating arm assembly of claim 8 , wherein the first end engages with the first aperture when the plunger is in the first position.

10 . The articulating arm assembly of claim 8 , wherein the first end engages with the second aperture when the plunger is in the first position, 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 extended 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 stowed 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: a structure interface; a first arm; a second arm rotatingly coupled to the first arm at a first hinge, wherein the second arm is configured to rotate relative to the first arm between a stowed orientation and an extended orientation; a mount assembly; wherein the mount assembly is adapted to be coupled to one or more electronic devices; and a rotation stop assembly disposed at least partially within the first hinge; wherein the rotation stop assembly is configured to:
permit clockwise rotation and limit counterclockwise rotation of the second arm relative to the first arm when the first arm rotates counterclockwise relative to the structure; and
permit counterclockwise rotation and limit clockwise rotation of the second arm relative to the first arm when the first arm rotates counterclockwise relative to the structure interface.

13 . The articulating arm assembly of claim 12 , wherein the first arm is one of an extension arm or a height adjustable arm, and wherein the second arm is one of an extension arm or a height adjustable arm.

14 . The articulating arm assembly of claim 12 , wherein the second arm is configured to overlap with the first arm in the stowed orientation, and the second arm is configured to rotate away from the first arm in the extended orientation.

15 . The articulating arm assembly of claim 14 , wherein the stowed orientation is one of a first stowed orientation, and a second stowed orientation, wherein the arm assembly is located on a left side of the structure interface in the first stowed orientation, and the arm assembly is located on a right side of the structure interface in the second stowed orientations.

16 . The articulating arm assembly of claim 15 , wherein the second arm rotates in counterclockwise direction relative to the first arm to place the arm assembly in the first stowed orientation, and wherein the second arm rotates in clockwise direction relative to the first arm to place the arm assembly in the second stowed orientation.

17 . The articulating arm assembly of claim 16 , wherein the rotation stop assembly is bi-directional, and wherein the rotation stop assembly is adaptable for a clockwise or a counterclockwise rotation of the second arm relative to the first arm, the rotation stop assembly further comprising a rotation stop ring, and wherein the rotation stop ring is coupled to the first arm.

18 . The articulating arm assembly of claim 17 , wherein the rotation stop ring comprises:
a recessed section, including; a first edge, and a second edge, and an overhung section, including; a first end proximate the first edge; and a second end proximate the second edge.

19 . The articulating arm assembly of claim 18 , wherein the second arm includes a boss having:
a first side; and a second side; wherein: the boss, the first side, and the second side rotate with the second arm; and the second side cooperates with the first end and the second edge cooperates with the second stop surface to place the arm assembly in the first stowed orientation.

20 . The articulating arm assembly of claim 19 , wherein the first side cooperates with the second end and the first edge cooperates with the first stop surface to place the arm assembly in the second stowed orientation.
