Abstract: An enclosure (1) for small animals, the enclosure comprising: an internal wall (17) that divides a space within the enclosure (1) into first (5) and second (7) regions, and a passageway (13) mounted in said internal wall (17) to extend between said regions (5, 7) so that an animal within the enclosure can pass between the first and second regions of the space; wherein the passageway (13) is movable relative to said internal wall (17) between a first operating mode in which an animal within the enclosure is able to pass between said regions and a second operating mode in which the animal is obstructed from passing between said regions.

Abstract: A multi-axle leaf spring suspension having a compliant equalizer. The leaf springs are mounted one behind the other on each side of the vehicle. Adjacent ends of the leaf springs are pivotally attached to the compliant equalizer. The compliant equalizer is pivotally mounted to a vehicle frame. The compliant equalizer comprises a pair of arms that are pivotally connected to each other in a scissor-like fashion. One end of each arm is pivotally connected to the end of a leaf spring. The other end of each arm is cooperatively arranged to contain and compress a spring member between them. The compliant equalizer reduces the magnitude of shocks that would be other wise transmitted to the suspension and frame by absorbing them through compression of the spring member.

Abstract: A sub-frame assembly for use with a vehicle having wheels such as a trailer is provided. The sub-frame assembly comprises two or more frame members, one or more cross members, and two or more stub torsion axle assemblies. Each of the stub torsion axle assemblies have a torsion arm, a spindle extending from the torsion arm for mounting one of the wheels, and a distal end extending from the stub torsion axle assembly for mounting to the frame assembly. The frame assembly may further comprise one or more shim plates for reception between the cross member and the distal end of the stub torsion axle assembly for allowing adjustment of the toe angle of the wheel assembly. In addition, the stub torsion axle assembly may be rotatably mounted to the cross member whereby the camber angle of the wheel assembly may be adjusted.
