Support apparatus

摘要

A support (e.g. for a television) has a platform 12 with a central spherical recess 18 which sits on a support member 22 which can slide along an arm 28. A bolt 30 extends down through a slot 20 in the recess 18, through apertures or bores 34 in the arm 28 and engages a member 42. The recess 18 forms a ball and socket joint on the member 22 which allows the platform to be tilted and swivelled unless the member 42 is tightened sufficiently to clamp the sliding surfaces together, preventing further movement.
