Abstract: A wheeled luggage case comprises (a) a storage chamber, (b) a cover defining an opening on at least one side of the storage chamber for providing ready access therein and at least two labyrinth axle-free wheels operatively connected to the chamber for towing the case along a ground surface. The labyrinth axle-free wheel comprises an internal rim, an external rim provided with a ground interface, rollers being rotatably disposed within a roller spacer between the internal and external rims in a uniform circumferential manner by means of a spacer and external covers. A labyrinth type dust passage in the wheel is defined by the rims and the external plates mechanically connected to the internal rim.

Abstract: An oven device (4) is adapted for use with a source of heat (24), such as a camp stove, and a cooking utensil (6), such as a covered (12) pot or pan (8), positioned over and separated from the heat source by a heat shield (20). The oven device includes a high temperature flexible, foldable convection dome, such as one made of aluminized fiberglass, having a vertically oriented sidewall (34) and a top (36). The top has a central vent opening (40). The convection dome is supported on the lid covering the pan by a number of radially extending pockets (42). The material from which the convention dome is made of is flexible enough to permit the convection dome to be folded up into a compact rectangular configuration but stiff enough to allow the pockets to support the convection dome above the lid of the pan with the sidewalls of the convection dome spaced apart from the sides of the pan.
