Abstract: A head cooling device for mounting over a person's head, generally within a headgear or a safety helmet. The device comprises: a housing, defining a main body enclosing a generally closed pocket, for containing ice cubes therein, a mouth, at one end of the main body, and an intermediate flooring, for supporting the ice cubes inside the pocket spacedly from the mouth. Thus, the flooring remains spaced at all times from the scalp by a spacing gap. The flooring is bored at its periphery, for enabling water droplets from the melting ice cubes to escape one at a time from the pocket, freely through the spacing gap and toward and against the person's head scalp. Flexible bands are used, integral to the housing, for releasably anchoring the housing to the head in generally overhanging fashion.

Abstract: This trailer comprises a U-shape load-carrying casing with a hitching bar across the free ends of the legs of the casing. The center of said cross-bar is hitched to the vehicle between the two wheels thereof by means of a universal joint hitch. The load carrying casing extends on both sides of the vehicle and across the back thereof. Two wheels support the back of the casing. The universal hitch enables the vehicle, such as a motorcycle, to roll, rotate or pitch relative to the trailer, such as when taking curves and/or riding on bumpy roads of grade and down-grade. The hitch is positioned below the horizontal plane passing through the vehicle axles and in front of the center of gravity of the vehicle. The trailer and vehicle assembly is very stable both while riding and braking. Also, the portions of the casing extending on both sides of the vehicle constitute a protection for the vehicle rider and passenger.
