Claim 0:
1. A runner assembly for carrying a receptacle towards and away from a structure, the runner assembly including:
at least one pair of first bearings, each first bearing being mountable to the structure so that the first bearings of the at least one pair are spaced apart;
an elongate runner defining a longitudinal length and having an opposed pair of first tracks spaced from each other, each first track configured to cooperate with the first bearings to allow the runner to be received between and carried by the first bearings;
a plurality of second bearings mounted to, and spaced longitudinally along, the runner; and
an elongate track member mountable to the receptacle, the elongate track member having a second track defining two pairs of opposed bearing surfaces comprising a pair of first bearing surfaces and a pair of second bearing surfaces spaced from each other and configured to cooperate with the plurality of second bearings, the runner defines a channel arranged, in use, to face the track member and the receptacle to receive the pairs of first and second bearing surfaces of the track member, and the plurality of second bearings are mounted within the channel to be concealed during operation of the runner, the plurality of second bearings being arranged in two rows extending longitudinally along the runner within the channel, the two rows spaced apart from each other towards the first tracks, the second bearings of one row arranged, in use, to abut the pair of first bearing surfaces, and the second bearings of the other row arranged to abut the pair of second bearing surfaces, and
each pair of bearing surfaces arranged to incline relative to each other such that each pair of bearing surfaces define a valley, each valley being configured to cooperate with the second bearings to constrain transverse displacement of the track member relative to the runner.
