Claim:
An arrangement for variably supporting a display, the arrangement comprising, (a) an overhead track, (b) a carriage coupled to said overhead track such that said carriage can be variably positioned along said overhead track, (c) a first arm coupled to and suspended from said carriage such that said first arm can be variably swiveled about the coupling to said carriage, (d) a second arm coupled to said first arm such that said second arm can be variably positioned in different inclinations to said first arm and such that said second arm can be variably swiveled relative to said first arm about a first swivel axis, and (e) a display coupled to said second arm by a subassembly, said subassembly comprising, (i) a swivel member, (ii) a mounting member affixed to a housing of said display, and (iii) an elongate member extending between and connecting together said swivel member and said mounting member, (iv) wherein, (A) said swivel member is coupled to said second arm such that said mounting member can be variably swiveled relative to said second arm about a second swivel axis, said second swivel axis generally extending in parallel relation to said first swivel axis, (B) said elongate member is mounted to, (I) said swivel member for movement relative to said swivel member about a first pivot axis, and (II) said mounting member for movement relative to said mounting member about a second pivot axis, said second swivel axis extending through said elongate member, and (C) said first pivot axis is coplanar with said second swivel axis, (f) wherein said second arm comprises a pair of parallel elongate members joined to form a four-bar-linkage parallelogram such that said first swivel axis and said second swivel axis remain in parallel relation during movement of said second arm between positions having varying inclinations to said first arm, and (g) wherein said first pivot axis intersects said second swivel axis.
