Abstract
Camping mattress having a head section and a foot section adapted to be rolled up for carrying, and being tapered in plan view such that at least one of the sections decreases in lateral dimension toward its outer end and the mattress is wider toward the center and narrower toward the end. The mattress has two sheets of flexible air-impervious material sealed together to form a plurality of chambers, a body of resilient material in one of the chambers, and a valve controlling air flow into and out of the chamber with the resilient material to regulate expansion and compression of the material.
Claims16
A camping mattress having a head section and a foot section adapted to be rolled up for carrying, and being tapered in plan view such that each of the sections decreases in lateral dimension toward its outer end and the mattress is wider toward the center and narrower toward the ends, a body of resilient material within the mattress, and valve means for controlling air flow to and from the resilient material to regulate expansion and compression of said material.
A camping mattress, comprising upper and lower sheets of flexible air-impervious material, means sealing the sheets together along a plurality of transversely extending lines to form a plurality of chambers between head and foot ends of the mattress, the chambers closest to the head and foot ends being tapered in plan view so that the mattress is wider toward its center and narrower toward the head and foot ends, a body of resilient material in one of the chambers, and valve means controlling air flow into and out of the chamber with the resilient material to regulate expansion and compression of said material.
A camping mattress, comprising upper and lower sheets of flexible air-impervious material which are tapered in plan view and decrease in lateral dimension toward head and foot ends of the mattress, means sealing the sheets together to form a chamber such that the mattress is wider toward its center and narrower toward the head and foot ends, a body of resilient material in the chamber, and valve means controlling air flow into and out of the chamber to regulate expansion and compression of the resilient material.
