Linear motion trolley and track systems for operable walls

A system for movably suspending an operable wall panel comprising:

• a track mountable to a ceiling, said track having a pair of horizontally and vertically displaced wheel supporting surfaces defining a channel therebetween, and a soffit portion below said wheel supporting surfaces;
• a trolley bolt having a proximal end disposed between said wheel supporting surfaces and a distal end extending through said channel for attachment to a wall panel;
• a first wheel rotatably mounted on said proximal end of said trolley bolt said first wheel having a surface supported on one of said wheel supporting surfaces;
• a second wheel rotatably mounted on said proximal end of said trolley bolt, said second wheel having a surface supported on the other of said wheel supporting surfaces;
• and
• a disc rotatably mounted on said trolley bolt adjacent said soffit portion of said track, said disc diametrically sized to prevent dislodgment of said wheels from said track when traversing a track intersection.

A system for movably suspending an operable wall panel comprising:

• a track, said track including a hanger bar mountable to a ceiling, a pair of soffit brackets in spaced relation defining a channel and downwardly depending from said hanger bar, and a contoured beam attached to said hanger bar, said beam having a first arm disposed adjacent one of said soffits and a second arm adjacent the other of said soffits;
• and
• a trolley blot having a proximal end disposed between said first and second arms and a distal end extending through said channel for attachment to a wall panel;
• a first wheel assembly rotatably mounted on said proximal end of said trolley bolt, said first wheel assembly having a surface supported on an end of one of said arms;
• a second wheel assembly rotatably mounted on said proximal end of said trolley bolt, said second wheel assembly having a surface supported on an end of the other of said arms, and at least one of said wheel assemblies including a compound supporting surface, said at least one wheel assembly being supported against vertical movement by two nonplanar surfaces at said end of a respective one of said arms.
