Abstract
A one piece rotationally molded cot for toddlers and other individuals includes a recessed sleeping surface supported above a raised bottom wall by a plurality of upwardly extending pillars. A closed dead air space between the bottom wall and sleeping surface and an additional air space beneath the bottom wall and above the room floor provide insulation for warmth. The cots nest in stacked relation for storage in minimum space. Dollies configured for conforming engagement beneath head and foot ends of the cots include swivel casters to facilitate transportation. Accessory items for use with the cot include a foam pad receivable in a fabric pad cover, a mattress, and a sheet. Cooperating VELCRO (.TM.) fasteners secure the cover to the cot and the sheet to the mattress.
Claims20
A cot, comprising:
- an elongated substantially hollow body possessing a closed curve construction, said hollow body rotationally molded from a plastic material;
- said body including a substantially planar sleeping surface intersecting an inclined head rest portion;
- a substantially enclosed insulating air space formed within said body beneath said sleeping surface;
- a second insulating air space disposed beneath said enclosed insulating air space and adapted to separate said enclosed insulating air space from a floor supporting said cot;
- a raised bottom wall at least partially defining said enclosed insulating air space;
- at least one pillar extending upwardly from said raised bottom wall for supporting said sleeping surface;
- said body including a top portion and a recessed bottom portion dimensioned to receive said top portion such that a plurality of identical cots may be stored in nested stacked relation;
- said top and bottom portions at least partially defined by a separating peripherally extending shoulder;
- at least one dolly including at least one rotatable element dimensioned for engagement with said cot to facilitate transportation and storage;
- said at least one dolly dimensioned for at least partial nesting within said recessed bottom portion;
- said at least one dolly including channel portions dimensioned for at least partial insertion of bottom edges of said cot and said dolly further including side walls dimensioned to at least partially overlie side wall portions of said cot;
- a pad;
- a cover for said pad;
- cooperating fasteners on said cover and said cot for releasably securing said cover and pad to said cot;
- a mattress;
- cooperating fasteners on said mattress and said cot for releasably securing said mattress to said cot;
- a laterally extending elastic strap on said mattress for securing said mattress in a rolled condition for transportation and storage;
- a sheet;
- and
- means for securing said sheet to said mattress.
