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.
1. A device, comprising:
a core arm structure configured to have a range of rotation based on an 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,
wherein the core arm structure extends from a rear end to a front end opposite the rear end,
wherein the floating stop key is movable within the track or tunnel within the core arm structure,
and wherein the range of rotation is further defined by a difference between a sum of an angle length of the track or tunnel and an angle length of the joint rotation stop structure, and twice a length of the floating stop key;
a rear axle located at the rear end;
a front axle at the front end; and
a linkage assembly extending from the rear end to the front end.
2. The device of claim 1 , wherein the core arm structure is operable to have a range of rotation of up to 360 degrees (180+/−degrees).
3. The device of claim 1 , wherein the floating stop key further includes stop faces that are movable within a predetermined range.
4. The device of claim 3 , wherein the stop faces are operable to prevent rotation of the rear axle.
5. The device of claim 1 , wherein the track or tunnel is dynamically formed based on pivoting components.
6. The device of claim 5 , wherein the pivoting components include a rear hinge structure, pivot stop disc, and the floating stop key.
7. The device of claim 1 , wherein the linkage assembly includes a spring element.
8. The device of claim 7 , wherein the spring element is configured to provide a gas spring counterbalance force.
9. The device of claim 7 , wherein the spring element is a non-adjustable gas spring counterbalance force including a non-adjustable friction pack element.
10. The device of claim 9 , wherein the non-adjustable friction pack element provides resistance to offset a sink or float caused by a weight of a payload.
11. The device of claim 9 , wherein the non-adjustable friction pack element is integrated with the rear axle, the front axle, or both.
12. The device of claim 1 , wherein the rear end is configured to be pivotably mounted either directly to a mount structure, or to an extension arm that in turn is mounted to the mount structure.
13. The device of claim 1 , wherein the front end is configured to be pivotably mounted to a front mount structure.
14. The device of claim 13 , wherein the front mount structure is operable to Dell rotate clockwise or counter clockwise with respect to the front end.
15. A support structure, comprising:
a rear mount structure;
a front mount structure for supporting a device; and
a core arm including:
a core arm structure configured to have a range of rotation based on an 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,
wherein the core arm structure extends from a rear end to a front end opposite the rear end,
wherein the floating stop key is movable within the track or tunnel within the core arm structure,
and wherein the range of rotation is further defined by a difference between a sum of an angle length of the track or tunnel and an angle length of the joint rotation stop structure, and twice a length of the floating stop key;
a rear axle located at the rear end;
a front axle at the front end; and
a linkage assembly extending from the rear end to the front end.
16. The support structure of claim 15 , wherein the core arm structure is operable to have a range of rotation of up to 360 degrees (180+/−degrees).
17. The device of claim 15 , wherein the linkage assembly includes a spring element, wherein the spring element is configured to provide a gas spring counterbalance force.
18. A method for supporting a device comprising:
pivotably mounting a core arm either directly or indirectly to a rear mount structure, wherein the core arm includes:
a core arm structure configured to have a range of rotation based on an 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,
wherein the core arm structure extends from a rear end to a front end opposite the rear end,
wherein the floating stop key is movable within the track or tunnel within the core arm structure,
and wherein the range of rotation is further defined by a difference between a sum of an angle length of the track or tunnel and an angle length of the joint rotation stop structure, and twice a length of the floating stop key;
a rear axle located at the rear end;
a front axle at the front end; and
a linkage assembly extending from the rear end to the front end; and
connecting a front mount structure to the front end of the core arm; and
connecting the device to the front mount structure.
