Abstract

An adjuster is to control operation of a lower joint and an upper joint. The lower joint couples a base to an arm, and the upper joint couples the arm to a mount. The adjuster controls the joints according to a first mode and a second mode. The first mode is to secure the lower and upper joints against adjustability. The second mode is to release the lower and upper joints for adjustability.

First claim

What is claimed is:

1. An apparatus comprising:
a base;
a lower joint to couple the base to an arm;
an upper joint to couple the arm to a mount;
an adjuster to control operation of the lower joint and the upper joint according to a first mode and a second mode, wherein the first mode is to secure the lower and upper joints against adjustability, and the second mode is to release the lower and upper joints for adjustability; and
a brake mechanism to secure and release at least one of the lower and upper joints in response to the adjuster, wherein the brake mechanism includes a locking gear secured to the base at an axis of rotation of the lower joint, and a plunger is slidably secured to the arm and pivotable with the arm about the locking gear, wherein the plunger is slidable to engage or disengage the locking gear based on a cable actuatable by the adjuster remotely from the brake mechanism, to secure or release the arm relative to the base.

2. The apparatus of claim 1 , further comprising:
at least one additional arm to couple the base to the mount via at least one corresponding set of additional lower and upper joints; and
an additional adjuster to control operation of the at least one additional lower and upper joints according to the first mode and the second mode.

3. The apparatus of claim 2 , Wherein the apparatus is to enable adjustability when both the adjuster and the additional adjuster are actuated, and disable adjustability when both are not actuated.

4. The apparatus of claim , wherein the lower and upper joints, when secured according to the first mode, are associated with a yield, threshold to enable a yield adjustability when the yield threshold is exceeded.

5. The apparatus of claim 4 , wherein at least one of the lower and upper joints is associated with providing audio feedback associated with exceeding: the yield threshold.

6. The apparatus of claim 1 , wherein the adjuster comprises a lever to pivot about an axis of rotation associated with the upper joint, wherein the lever is to extend from the axis of rotation to provide an actuation portion of the lever proximate and substantially parallel to the mount.

7. The apparatus of claim 1 , further comprising a dutch mechanism to secure and release at least one of the lower and upper joints in response to the adjuster.

8. The apparatus of claim 1 , wherein a plunger actuation range of motion is to correspond to an adjuster actuation range of motion, independent of variations in a service length between the adjuster and the brake mechanism throughout a range of motion of the lower and upper joints.

9. The apparatus of claim 1 , wherein the cable is enclosed by a sheath, and the cable and sheath have an extended length that is to exceed a service length between the brake mechanism and the adjuster, to accommodate relative changes in the service length throughout the range of motion of the lower and upper joints.

10. An apparatus comprising:
a base;
a first arm to couple the base to a first mount via a first lower joint and a first upper joint;
a second arm to couple the base to a second mount via a second lower joint and a second upper joint. wherein the first and second mounts are to receive a display;
a first adjuster associated with the first arm to control operation of the first upper and lower joints according to a first mode and a second mode, wherein the first mode is to secure the first upper and lower joints against adjustability, and the second mode is to release the first upper and lower joints for adjustability; and
a second adjuster associated with the second arm to control operation of the second upper and lower joints, according to the first and second modes as applied to the second upper and lower joints, wherein the first and second adjusters are positioned proximate to edges of the display such that an edge of the display and a corresponding one of the first and second adjusters are grippable together to actuate the first and second adjusters to position the display.

11. An apparatus comprising:
a base;
a first arm to couple the base. to a display via a first lower joint and a first upper joint;
a second arm to couple the base to the display via a second lower joint, and a second upper joint;
a first adjuster associated with the first arm to control operation of the first upper and lower joints according to a first mode and a second mode, wherein the first mode is to secure the first upper and lower joints against adjustability, and the second mode is to release the first upper and lower joints for adjustability; and
a second adjuster associated with the second arm to control operation of the second upper and lower joints, according to the first and second modes as applied to the second upper and lower joints, wherein the first and second adjusters are positioned proximate to edges of the display such that an edge of the display and a corresponding one of the first and second adjusters are grippable together to actuate the first and second adjusters to position the display.

12. The apparatus of claim 11 , wherein the first and second upper and lower joints are adjustable to position the display within a range of motion including a lower flat position and an upper vertical position.
