Abstract

A cantilever mounting device includes a front member on which an object is mounted and a back member for attachment to a load-bearing surface. A first arm is connected to the back member to form a rotatable first joint. A second arm is connected to the first arm to form a rotatable second joint. The front member is connected to the second arm to form a rotatable third joint. The first joint includes a first cam including a first lever and a first shaft for connecting the back member to the first arm. The first cam allows rotation about an axis of the first joint when the first lever is set to a first adjustment position. The first cam does not allow rotation about the axis of the first joint when the first lever is set to a first locked position.

BACKGROUND OF THE INVENTION

[0001] 1. Field of the Invention

[0002] This invention relates to tension adjustment for a cantilever mounting device.

[0003] 2. Description of Related Art

[0004] Flat panel displays have become increasingly popular in home entertainment systems. Generally, flat panel displays have a limited viewing angle, thus making the positioning of the display important to a viewer. Flat panel displays are typically placed on stands or are mounted to a wall by flat panel mounting devices. These mounting devices include articulating joints and are conventionally preset with an optimal joint / tilt tension during manufacturing to the joints of the articulating components and tilt mechanisms. The preset tension allows the flat panel mounting device to steadily and predictably hold a display in place. However, periodic adjustment is required to readjust the tension of the joints and tilt mechanism to maintain a desired viewing position. Furthermore, if a user decides to change a ...
