Abstract:
1. A carriage assembly for mounting to a track defining a helical path about a longitudinal axis of the track, said assembly comprising: a single trolley mountable to said track through a track engagement assembly, an orientation of the trolley varying with an orientation of the track; a carriage support rotationally mounted to the trolley, using a first rotational means, so as to permit rotation of the carriage support about a first axis relative to the trolley; and a carriage rotationally mounted to the carriage support, using a second rotational means, so as to permit rotation of the carriage about a second axis relative to the carriage support, wherein the carriage is configured to be engaged with the track via said one single trolley, wherein the second rotational means is arranged such that under the influence of gravity, the carriage is biased to a horizontal orientation, and rotation about the first and second axes is arranged to maintain the carriage in the horizontal orientation independent of the orientation of the track.
