Patent ID: 8746635

Claim:
A supporting apparatus for a display device, the supporting apparatus comprising: a stationary base configured to be coupled to an installation surface; a device supporter configured to support a display device; a connection device that connects the stationary device to the device supporter and that guides motion of the device supporter; and a tilting frictional device interposed between the connection device and the device supporter and that guides a tilting motion of the device supporter, wherein the tilting frictional device comprises: a first arc guide fixed to the connection device; and a second arc guide fixed to the device supporter and engaged with the first arc guide, wherein the first arc guide and the second arc guide each include a plurality of frictional projections formed thereon and a plurality of frictional grooves formed therein, wherein the plurality of frictional projections formed on the first arc guide are received in and are configured to move along the plurality of frictional grooves formed in the second arc guide and the plurality of frictional projections formed on the second arc guide are received in and arc configured to move along the plurality of frictional grooves formed in the first arc guide such that a frictional force is generated by contact between inner surfaces of the frictional grooves and corresponding wall surfaces of the frictional projections as the device supporter moves relative to the connection device.
