US 6,409,134 B1 · Arm apparatus for mounting electronic devices with cable management system

Abstract

An extension arm suitable for mounting a flat-screen electronic peripheral device, such as a computer monitor or television, comprises a forearm extension that has at one end a first coupling for attachment to a tilter, a platform or other means for supporting a flat-screen device and at the other end a second coupling with a slot formed therein. The extension arm also comprises a pair of endcaps, each having a shaft. The shaft of the first endcap is pivotably rotatable in a support mount, such as a wall, desk or pole mount. The shaft of the second endcap is hollow and is pivotably rotatable in the second coupling of the forearm extension. The extension arm also comprises an upper channel and a lower channel. Each channel has at opposite ends integrally cast rollers which are pivotably attached to each of the endcaps. The lower channel has a cable channel formed therein. The upper and lower channels and the endcaps form an adjustable parallelogram. The shape of the parallelogram is retained by a gas spring, which is attached at a first end to a ball stud mounted in the upper channel and adjustably mounted at a second end to the first endcap. A clevis is located within the first endcap and is pivotably attached to the second end of the gas spring. A threaded rod threadedly engages the clevis, such that the clevis slides within the first endcap when the rod rotates around its axial centerline. A cable from the flat-screen device can be hidden from view by being disposed within the forearm extension, the second endcap, and the lower channel of the extension arm.

Dependent claims

An extension arm for adjustably mounting a device to a support mount and hiding cables to and from the device within said extension arm, said extension arm comprising:

a forearm extension having a body, means for attachment to the device disposed at a first end of said body, and a second end coupling disposed at a second end, said second end coupling having a cable slot formed in a wall thereof so that said second end coupling and said body are in communication with each other through said cable slot;
a first endcap including a support shaft for attachment to the support mount;
a second endcap including a partially enclosed housing and a hollow shaft, said hollow shaft pivotably attached to said second end coupling;
an upper channel having a first roller disposed at a first end and configured to be pivotably attached to said first endcap, and a second roller disposed at a second end and configured to be pivotably attached to said second endcap;
a lower channel having a third roller disposed at a first end and configured to be pivotably attached to said first endcap, a fourth roller disposed at a second end and configured to be pivotably attached to said second endcap, and a cable channel formed therein that runs longitudinally along said lower channel from a point close to the first end of said lower channel to the second end of said channel so as to cut through said fourth roller and form an opening in the second end of said lower channel;
and
a gas spring rotatably attached at a first end to said upper channel and adjustably attached at a second end to said first endcap, wherein said gas spring is configured to retain said upper channel, said lower channel, said first endcap and said second endcap in a parallelogram shape when the device is positioned.
