  • Patent number: 5445137
    Abstract: A lightweight, portable cooking unit for use in tents is disclosed. It is designed for use in the mountains, where lightweight equipment is essential. The unit will fit in a backpack when disassembled. The heating chamber has a lower burner unit to hold a common mountain stove burner such as those developed by MOUNTAIN SAFETY RESEARCH. The heating chamber vents to a stack that transmits the combustion gases and moisture safely outside the tent by means of a tent roof jack that protects the fabric from the heat. The stack is also fed with ambient air that mixes with the combustion to cool the exhaust to safe levels. The device can be disassembled and stored in a compact package.

  • Patent number: 4999864
    Abstract: A bed having upper and lower bunks. In order to make it easy to "make" the bed the upper bunk can be moved sidewise and then tilted to give a person desiring to make the bed easy access to the upper bunk. The axis about which the upper bunk is tilted may be selected to enable the tilted bunk to be higher or lower as desired. The movement of the bunk is provided by cam surfaces on the frame of the bed and cam followers on the mattress trays of the upper bunk. One set of cam followers act as a pivot to enable the rotation of the upper bunk. Locks are provided to hold the mattress tray in either its normal position or its tilted position.
