Incorporating cam into rail of rotational mount

A method of operating a rotationally-mounted display system, the rotationally-mounted display system comprising a display device and a support structure connected to the display device via a mechanical interface, the mechanical interface comprising three or more rail segments including a cam rail segment comprising a cam, wherein the cam rail segment comprises at least a first detent and a second detent, and for each rail segment, one or more corresponding rollers, a roller for the cam rail segment being a follower that contacts the cam rail segment, wherein the follower is configured to move relative to the cam rail segment, and the follower being coupled with a spring configured to bias the follower toward the cam rail segment, the method comprising:

• rotating the display device a first portion of a rotational adjustment by moving the follower for the cam rail segment out of the first detent in the cam rail segment and along a first portion of the cam rail segment, thereby compressing the spring, wherein the spring provides resistance to rotation of the display device towards the first detent, wherein the resistance to the rotation provided by the spring varies as a function of a location of the follower along the cam rail segment based upon a width of the cam rail segment between the first detent and the second detent;
• and
• rotating the display device a second portion of the rotational adjustment by moving the follower for the cam rail segment along a second portion of the cam rail segment and into the second detent in the cam rail segment, thereby relaxing the spring, such that the spring holds the display in a position corresponding to the second detent.

A rotational mounting system for a display device, the rotational mounting system comprising:

• a display mount configured to be mounted to the display device;
• a support structure configured to be mounted to another structure;
• and
• a mechanical interface rotationally connecting the mount and the support structure, the mechanical interface comprising
• three or more rail segments including a cam rail segment comprising a cam, wherein the cam rail segment comprises at least a first detent and a second detent, and
• for each rail segment, one or more corresponding rollers, a roller for the cam rail segment being a follower that contacts the cam rail segment, wherein the follower is configured to move relative to the cam rail segment, the follower being coupled with a spring configured to bias the follower toward the cam rail segment, wherein a width of the cam rail segment varies along a length of the cam rail segment between the first detent and the second detent, such that movement of the follower along the cam rail segment between the first detent and the second detent varies a compression of the spring to provide varying resistance to rotation of the display device as a function of a location of the follower along the cam rail segment.
