A rail for a track for a wheeled vehicle is generally elongated and has a substantially "I" transverse cross section providing an upper rail head and a lower rail foot joined by a web. The rail head is provided with at least one and preferably two laterally spaced apart longitudinally extending apertures, which are adapted to receive alignment pins so that when the rails are coupled to each other substantially end on end, the pins extend between abutting ends of the rails to maintain the rails in an abutting and substantially aligned relationship. A track is also provided including spaced apart rails with a plurality of spacers extending between the spaced apart rails to maintain the rails in a predetermined spaced apart relationship. The spacers can be pivotally mounted on the rails, so that the rails are able to move and pivot relative to each other such as for the adjustment of gauge, packaging, and transport. The track can be used with rails which are substantially parallel to one another or with rails which are of a generally arcuate or curved configuration relative to each other.
A track for a wheeled vehicle, comprising a pair of rails, each rail being elongated and having a substantially "I" transverse cross section, each of said rails having an upper rail head and a lower rail foot joined by a web, each of said rail heads having at least two laterally spaced apart apertures to receive alignment pins to couple and engage a plurality of rails one to the other with aperture pins extending between abutting ends of said rails to maintain said rails in an abutting and aligned relationship, at least one spacer being provided for each of the pair of rails, said at least one spacer extending between said pair of rails, the at least one spacer being pivotally secured to each of said rails in the pair to allow relative movement between said rails in the pair toward and away from each other, said track further comprising a flange on said web, said flange extending outwardly from said web, and wherein ends of said at least one spacer are secured to said rails within a recess defined by an upper surface of the rail foot and an underside of the flange.
A rail for a track upon which a wheeled vehicle is to pass, said rail being generally elongated and having a substantially "I" transverse cross section, said rail having an upper rail head and a lower rail foot joined by a web, said rail head having at least one longitudinally extending aperture defined therein, said at least one aperture having a longitudinally extending slot in an outer side surface thereof, said slot extending the length of said aperture, such that said at least one aperture is open-faced along the outer side thereof, said at least one aperture receiving at least part of an alignment pin to couple said rail to a corresponding rail, one end of said rail abutting an end of said corresponding rail when the rails are coupled, said alignment pin including adjustment means for adjusting positioning of said pin relative to the longitudinal axis of said aperture in said rail, said pin extending between the abutting ends of said rail and corresponding rail to maintain the rails in an abutting and aligned relationship.
A track for a wheeled vehicle, comprising a pair of rails, each rail being elongated and having a substantially "I" transverse cross section, each of said rails having an upper rail head and a lower rail foot joined by a web, each of said rail heads having at least two laterally spaced apart apertures defined therein, said two apertures each having a longitudinal axis and each receiving an alignment pin to thereby couple and engage a plurality of rails one to the other with the alignment pins extending between abutting ends of said rails which are in an abutting and aligned relationship, said alignment pins including adjustment means for adjusting positioning of said pins relative to the longitudinal axes of the apertures in said rail, each aperture having a longitudinally extending slot in an outer side surface thereof, said slots extending the length of said apertures such that said apertures are open-faced along the outer sides thereof.
