Abstract: Collapsible combustion containers are disclosed and described. Such combustion containers generally include a plurality of vertically oriented panels joined by hinges. The hinges include hinge pins that can be configured to form at least part of a base that supports the container or at least part of a heating platform above the container or both. Further, the panels can contain one or more fuel openings which allow a user to control placement of fuel in the container inserted from each opening so as to select a point inside the container where the fuel will converge and combust.

Abstract: A hitch support mechanism is positionable in a vertical direction to adjust for the hitch height of a trailing vehicle. The hitch support may be adapted to be removably attachable to a receiver fixed to a vehicle. The hitch support may be configured as a four-bar linkage in which a fixed link is secured by a trunnion to the receiver of a towing vehicle. A translating link may support directly attachment of a hitch, such as a ball hitch. Two rotating links, spaced from one another may extend parallel to one another. The rotating links connect the fixed link to the translating link. The rotating links each rotate about a respective axle, remaining parallel with respect to one another. An adjustment mechanism may fix the relative position of the translating link with respect to the fixed link. A system of apertures and a pin may provide a very compact adjustment mechanism, resulting in a light weight and compact envelope for the hitch support.

Abstract: An apparatus for carrying bicycles on a vehicle includes a trunnion fitted to a receiver or other mount secured to a vehicle. A base extends from the trunnion longitudinally away from the vehicle to carry a post having top and bottom supports extending away for supporting bicycles. One or more trays may extend laterally across the lower support with respect to the base. Each tray may be adapted to support the rear tires of two bicycles. The upper support may be an arm having adjustable blocks for mounting the open (free) ends of the tines of the forks of the bicycles. Each block is slotted to receive and position a skewer passing through a fork. The skewer may be positionable along a length of a block, to adjust to the length of a bicycle. The blocks may be mounted in a different orientation (e.g. upside down) to further adjust for bicycle length. Trays and blocks may be arranged to offset every bicycle from every other bicycle in three dimensions to avoid interference of handlebars and pedals.
