Abstract

Abstract A portable unitary covered cot foldable into a compact condition suitable for transportation by a single individual comprising a foldable rectangular frame formed by two pivotally connected Ushaped frame members. U-shaped support legs are pivotally attached to the frame at each end and in the center. U-shaped support arms to support a flexible cover attached to the frame are pivotally connected to each end of the frame. The cot is foldable from an open, horizontal position where the legs and arms extend from the frame to a closed position where the support legs are positioned against the exterior of the frame and the support arms and cover are enclosed by the folded U-shaped frame members. One important aspect of the cot structure is the provision of telescoping sides for each of the U-shaped frame members. In the retracted and folded position, the cot is quite compact and the cot structure is more readily transportable on a person''s back. In the open position, the U-shaped frames are fully extended so that the cot structure is of a length sufficient for a person to sleep therein.

Claims Analysis

Total Claims: 13
Claim 1
Independent Claim 359 words
A unitary covered camping cot foldable into a compact condition suitable for transportation by a single individual which comprises: a. a foldable rectangular frame comprising a pair of pivotally connected lightweight U-shaped frame members, and means for pivotally connecting the open end portions of each U-shaped frame member; b. a pair of lightweight U-shaped end support legs, the open end portion of each being pivotally connected transversely to the side portions of each U-shaped frame member in close proximity to the closed end portions of each frame member; c. a lightweight U-shaped intermediate support leg, the open end portions of which being pivotally connected transversely to the frame in close proximity to the open end portions of the frame members; d. a single pair only of inverted, lightweight U-shaped support arms, the open end portions of each being permanently pivotally connected transversely to the side portions of each U-shaped frame member in close proximity to the closed end portions of each U-shaped frame member; e. means attached to the frame for defining a support surface across the rectangular frame for the horizontal support of an individual; f. a flexible cover attached to the rectangular frame having an access opening and ventilation opening therein, said arms being positioned between said cover and said support surface; and, g. the camping cot being foldable, from a horizontal, open position as said inverted U-shaped support arms are in a generally upright position and define flexible side support means for said flexible cover and define a chamber above and between said support arms, said single pair of U-shaped arms defines the sole support means for said cover when said cover is in the chamber defining position, and the U-shaped support legs extend downward to maintain the cot in a stable position, to a closed, portable, compact condition where the support legs and support arms are positioned longitudinally inward against the side portions of the frame and the U-shaped frame members folded together such that the frame members are generally parallel and substantially enclose both the flexible cover and the support arms and the support legs are positioned against the exterior of the frame members.
Claim 2
Dependent Claim 359 words
A unitary covered camping cot foldable into a compact condition suitable for transportation by a single individual which comprises: a. a foldable rectangular frame comprising a pair of pivotally connected lightweight U-shaped frame members, and means for pivotally connecting the open end portions of each U-shaped frame member; b. a pair of lightweight U-shaped end support legs, the open end portion of each being pivotally connected transversely to the side portions of each U-shaped frame member in close proximity to the closed end portions of each frame member; c. a lightweight U-shaped intermediate support leg, the open end portions of which being pivotally connected transversely to the frame in close proximity to the open end portions of the frame members; d. a single pair only of inverted, lightweight U-shaped support arms, the open end portions of each being permanently pivotally connected transversely to the side portions of each U-shaped frame member in close proximity to the closed end portions of each U-shaped frame member; e. means attached to the frame for defining a support surface across the rectangular frame for the horizontal support of an individual; f. a flexible cover attached to the rectangular frame having an access opening and ventilation opening therein, said arms being positioned between said cover and said support surface; and, g. the camping cot being foldable, from a horizontal, open position as said inverted U-shaped support arms are in a generally upright position and define flexible side support means for said flexible cover and define a chamber above and between said support arms, said single pair of U-shaped arms defines the sole support means for said cover when said cover is in the chamber defining position, and the U-shaped support legs extend downward to maintain the cot in a stable position, to a closed, portable, compact condition where the support legs and support arms are positioned longitudinally inward against the side portions of the frame and the U-shaped frame members folded together such that the frame members are generally parallel and substantially enclose both the flexible cover and the support arms and the support legs are positioned against the exterior of the frame members.
