Multi-directional carrier system for operable partitions

A multi-directional carrier comprising, in combination,

• a track,
• first and second ledges on said track, said ledges relatively spaced vertically and horizontally to define a slot therebetween,
• support means positioned between said ledges in said slot,
• first and second discs positioned on said support means in vertical spaced relation,
• one of said discs engaging one of said ledges and the other disc engaging the other of said ledges,
• means on each of said discs defining a downwardly facing, linear angled surface,
• means on the upper side of each of said ledges defining an upwardly facing, linear angled surface in engagement with the angled surface of a respective one of said discs, said ledge angled surfaces being complementary to said disc angled surfaces, and
• the angle of both said disc angled surfaces and said ledge angled surfaces being at an angle to the horizontal of substantially 5.degree..

A multi-directional carrier and track comprising, in combination,

• a track,
• means on said track defining first and second disc supporting surfaces relatively spaced horizontally and vertically and defining a slot between said disc supporting surfaces,
• first and second discs,
• means defining an axis and supporting said first and second discs for rotation about said axis and with said first disc in engagement with one of said disc supporting surfaces and said second disc in engagement with the other of said disc supporting surfaces, and
• means defining a linear, angled surface on one of said disc supporting surfaces and said discs, the angle of said linear surface being substantially 5.degree. to the horizontal and sloping inwardly and downwardly toward said slot.
