Movable wall panel systems

Claim 2

A trolley for supporting a wall panel in a track system in which track sections define slots and in which track sections mutually intersect, comprising a yoke having a body, means for suspending said wall panel from said body, two pairs of axially aligned wheels for rolling on said track sections and rotatably supported by said body with the axis of said pairs at right angles to each other, the lowermost running surfaces of said wheels defining a common plane, a series of peripherally spaced platforms carried by said yoke and positioned in the arcuate spaces between adjacent wheels and having lower support surfaces defining a plane spaced above the plane of said running surfaces for engaging said track sections when said trolley wheels encounter a track intersection to prevent said wheels from dropping fully into the intersecting track slots and for slidably supporting said trolley on said track sections until a pair of wheels engage the track sections of an adjacent or intersecting track to provide a smooth and relatively effortless transitional movement of said trolley through said intersection.

Claim 3

In a movable wall panel system which includes a series of trolley-supported wall panels and at least two mutually intersecting tracks in Which said tracks include parallel spaced-apart trolley-wheel sections defining slots therebetween, the combination with trolleys for supporting said wall panels comprising a yoke body in each said trolley, a transverse axle supported by said body, a pendant bolt having a body portion mounted on said transverse axle member and a shank portion rigidly connected to a said wall panel for suspending said wall panel from said body, a first pair of trolley wheels on said axle for selectively engaging said trolley wheel sections, bolts supported by said body at right angles to said axle supporting a second pair of said wheels at right angles to said first pair, means on said yoke body defining support surfaces positioned generally in the arcuate spaced between said wheels including a series of four peripherally spaced platforms formed integrally with and cantilevered from said body in the space between adjacent said wheels, said platforms defining a horizontal plane spaced slightly above the rolling plane of said wheels and proportioned to engage said track sections when said trolley encounters a track intersection providing support for said trolley and providing for sliding of said trolley on said track sections until said wheels are established on the track sections of an adjacent or an intersecting said track resulting in a smooth and relatively effortless transitional movement of said trolley through such intersection.

Claim 4

In a movable wall panel system which includes a series of trolley-supported wall panels and at least two mutually intersecting tracks in Which said tracks include parallel spaced-apart trolley-wheel sections defining slots therebetween, the combination with trolleys for supporting said wall panels comprising a yoke body in each said trolley, a transverse axle supported by said body, a pendant bolt having a body portion mounted on said transverse axle member and a shank portion rigidly connected to a said wall panel for suspending said wall panel from said body, a first pair of trolley wheels on said axle for selectively engaging said trolley wheel sections, bolts supported by said body at right angles to said axle supporting a second pair of said wheels at right angles to said first pair, means on said yoke body defining support surfaces positioned generally in the arcuate spaced between said wheels including a series of four peripherally spaced platforms formed integrally with and cantilevered from said body in the space between adjacent said wheels, said platforms defining a horizontal plane spaced slightly above the rolling plane of said wheels and proportioned to engage said track sections when said trolley encounters a track intersection providing support for said trolley and providing for sliding of said trolley on said track sections until said wheels are established on the track sections of an adjacent or an intersecting said track resulting in a smooth and relatively effortless transitional movement of said trolley through such intersection.

Claim 5

The combination defined in claim 2 wherein each of said platforms in a generally triangular disc defined by an arcuate outer surface which extends between a pair of generally converging side surfaces, and wherein each side surface cooperates with a corresponding side surface from the next peripherally spaced platform to define a space for receiving a lower portion of a wheel therebetween.

Claim 6

The combination of claim 2 further comprising a centering roller in said slot on said pendant bolt.
