ABSTRACT:
An extendable and flexible trailer mechanism according to the present invention is adapted to be towed by a tractor on a roadway and the length of the trailer mechanism is adjustable between minimum and maximum lengths in order to accommodate loads of varying length. The trailer mechanism may include front and rear chassis means, the spacing of which may be varied by varying the position of a telescoping flexible connector element that has telescoping relationship with at least one of the chassis means. Each of the chassis means may be supported by separate wheel and axle assemblies that may be disposed in justaposed relation in the contracted condition of the trailer mechanism and may be disposed in spaced relation in the extended condition thereof. The chassis means may cooperate in such a manner that they are disposed in substantially rigid relation when the trailer mechanism is contracted and, through the flexible connection therebetween, have substantial relative movement when the trailer mechanism is extended. Locking devices are provided to secure the chassis structures in assembly both in the contracted and extended condition of the trailer mechanism.
