Patent ID: 8695165

Claim:
A bogey assembly comprising: a body configured to carry a cantilevered hanger bolt toward one end of the body, and to support the hanger bolt in an overhead track so that the bolt hangs in a vertical orientation through a channel in the track, the track being formed of a top rail section and a bottom rail section with rails on either side of the channel; only a single set of wheels to provide rolling support of the body on the rails, the set of wheels being positioned toward the one end of the body and comprising a wheel mounted on an axle on either side of the body; and a set of rollers for rolling engagement against an underside of the top rail section of the track, the set of rollers comprising two rollers positioned toward an opposite end of the body from the set of wheels, on either side of the body, wherein: the set of rollers are in an elevated position relative to the set of wheels so that, when in use, the bolt hangs in the vertical orientation, the rollers engage the underside of the top rail section and the set of wheels engage the rails, whereby: the set of rollers counterbalance rotational forces applied to the body through the cantilevered hanger bolt.
