ABSTRACT:
A rolling key for rolling up sleeping bags and the like is provided. A pair of tubular plastic rods are pivotally attached at one end, one of the rods being pivotally displaceable to a position parallel to and spaced from the other rod forming an open ended fork or key. A metal hook inserted through holes in the free ends of the rods fastens the free ends together and clamps a sleeping bag securely between the rods. In use the rolling key provides sufficient widthwise rigidity to easily roll the sleeping bag. A handle attached to attached end of the non-pivotable rod allows the rolled sleeping bag to tightly compress the rolled bag in a compact bedroll.
