Patent ID: 7143474

Claim:
A track system for rolling apparatus, said track system having at least two adjacent track sections each of which comprises: a track base extending between a first base end and a second base end thereby to define a track base length, and being formed with a rail channel; a track rail extending between a first rail end and a second rail end thereby to define a track rail length that is substantially equal to the track base length, said track rail being disposed in said rail channel with said first rail end projecting beyond said first base end thereby to define a rail projection, and with said second rail end being recessed from said second base end thereby to cause said channel to define a rail projection socket in said track base; and coupling means (a) for preliminarily coupling adjacent track sections together with said rail projection of one track section received in said rail projection socket of an adjacent track section and permitting relative movement between said rails and said bases of said adjacent track sections thereby to substantially close any spaces between adjacent bases and between adjacent rails, and (b) for fixedly securing said adjacent rail sections together after any such spaces have been closed, said coupling means including a coupling bar, wherein, at said rail channel, said track base at said first base end is in between said coupling bar of said coupling means and said track rail, in a vertical arrangement.
