Abstract:

A bed comprising a hammock and insulated sleeping bag wherein the insulation of the bottom of the bag is placed underneath the hammock to avoid compression by the sleeper and the remainder of the bag is attached to the upper surface of the hammock to cover the occupant, with the hammock portion located between permanently attached edges of the bag serving as a block baffle to the insulation; and a tent combined with said bed to form a shelter by removably attaching the lower edges of the tent to the edges of the hammock, providing an apron to carry off water to below the line of attachment, and suspending the tent over the hammock and bag from the same two supports sustaining the hammock and using cords between the upper surface of the bag and the tent ridge to raise the upper portion of the bag for cooling when desired; and a similar bed for two sleepers equipped with movable cords or tapes running between the spreader bars to divide the hammock into separate sleeping places while allowing for varying weight and girth of the occupants, with a spreader bar of such height in the center compared to the ends as to provide for matching the slopes of the sides of the hammock for each sleeping space, to which double bed the tent may be combined in the same fashion as for a single bed; and a hammock comprised of cloth of varying width, like an hourglass in appearance when flat, so that the longitudinal center line thereof may be kept straight and level while at the same time achieving a degree of sag of the edges of the hammock necessary to stability, the amount of such sag while keeping the center line straight being the result of variation in the width of the cloth between the waist and ends of the hammock along the curve therein.
