Abstract: The present invention relates to a steering system for use in a vehicle or carrier. In embodiments, the steering system comprises a first tilt shaft for connecting to a first load-bearing body of a vehicle and a second tilt shaft for connecting to a second load-bearing body of a vehicle. In embodiments, a spacer element connects the first tilt shaft to the second tilt shaft. The spacer element and tilt shafts are adapted such that the first tilt shaft and second tilt shaft are capable of partially rotating about the longitudinal direction of the tilt shafts independently of each other. The invention also relates to a vehicle, carrier and/or a split deck pushboard comprising one or more embodiments of the steering system.

Abstract: A vehicle includes a load-bearing body having a front end and a rear end, at least one carrier supporting the body on a surface on which the vehicle is positioned, and a steering device. The steering device includes at least one wheel and at least one castor-type wheel attached to the body and tiltable about a longitudinal axis of the body. In use, the at least one wheel and the at least one castor-type wheel contact a support surface and the vehicle is steerable by tilting the at least one castor-type wheel and the at least one wheel about the longitudinal axis.

Abstract: A device useful in the closing of the zipper of a plastic bag has an elongate hollow body with one or more sidewalls. A linear sidewall slit is defined within the sidewalls. The sidewall slit is disposed parallel to the longitudinal axis of the body and runs along the entire length of the body. A closer element is disposed within the body. The closer element has a pair of opposed biased surfaces disposed proximate to one another to form a trough. The biased surfaces are spaced apart at the base of the trough by a closer element slit having a width which is the same or slightly smaller than the combined thickness of the plastic bag and zipper combination. The closer element slit is disposed in communication with the sidewall slit. In a typical embodiment, the intersection of the closer element slit and the sidewall slit forms a single L-shaped combined slit.
