Display support with first and second arms and mechanism for maintaining constant orientation of the plane bisecting the range of rotation of the second arm relative to a support base

摘要

The display supporting apparatus includes a base, a first arm, a second arm, and a display attachment bracket designed to be fixedly securable or attachable to a display. The display support apparatus further includes a mechanism for providing a constant orientation in relation to the base for the plane bisecting the range of rotation of the second arm about the pivot axis between the first arm and the second arm even as the first arm moves pivotally relative to the base.

主权项

1. A display support apparatus for supporting a display at a user selected location and position relative to a support structure, the display support apparatus comprising:
a base adapted for attachment to the support structure; a first arm having a range of rotation about a first pivot axis between said first arm and said base; a second arm having a range of rotation about a second pivot axis between said first arm and said second arm and said second arm having a range of rotation about a third pivot axis, wherein said third pivot axis is perpendicular to said second pivot axis; rotation stops that limit the range of rotation of the first arm relative to the base about said first pivot axis; and a mechanism for providing an orientation of a plane containing said second pivot axis and bisecting an angle defined by said range of rotation of said second arm about said second pivot axis, said mechanism comprising a torque transfer arrangement and wherein said orientation is constant as said first arm moves relative to said base.
