Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
150 words
A portable, foldable cot frame, for supporting a rectangular, elongated sheet of material having a plurality of elongated slots provided on the periphery thereof, comprising: a plurality of rigid, lateral support members, disposed through the slots in the sheet of material; a plurality of coupling members, having at least two pivotable support members affixed thereto, said pivotable support members being slidably coupled to said lateral support members; at least two end support members, for supporting the ends of the cot during use, having detachable coupling means affixed to the ends thereof for pivotably and detachably coupling said end members together and providing an enclosure for the disassembled structural members comprising the cot frame; and at least one pair of support legs, pivotably coupled at a selected point along their length so as to be foldable, having the ends thereof detachably coupled to said coupling members, for supporting said cot frame.
Claim 2
Dependent Claim
150 words
A portable, foldable cot frame, for supporting a rectangular, elongated sheet of material having a plurality of elongated slots provided on the periphery thereof, comprising: a plurality of rigid, lateral support members, disposed through the slots in the sheet of material; a plurality of coupling members, having at least two pivotable support members affixed thereto, said pivotable support members being slidably coupled to said lateral support members; at least two end support members, for supporting the ends of the cot during use, having detachable coupling means affixed to the ends thereof for pivotably and detachably coupling said end members together and providing an enclosure for the disassembled structural members comprising the cot frame; and at least one pair of support legs, pivotably coupled at a selected point along their length so as to be foldable, having the ends thereof detachably coupled to said coupling members, for supporting said cot frame.
Claim 3
Dependent Claim
53 words
The cot frame as recited in claim 1, wherein said end support members are rectangular-shaped, and have detachable hinges affixed at one end, and detachable fastening clamps affixed to the other end, for pivotably and detachably coupling said end members together so as to provide a rectangular-shaped enclosure for carrying the cot frame.
Claim 4
Dependent Claim
73 words
The cot frame as recited in claim 1, wherein said lateral support members have recesses in the ends thereof, wherein said coupling members further comprise a hollow projecting member, and support rods affixed to the ends of said pivotable support members for slidable disposal within said recess provided in said lateral support members, and wherein the ends of said support legs are slidably disposed in said projecting members provided on said coupling members.
Claim 5
Dependent Claim
51 words
The cot frame as recited in claim 3, further comprising a plurality of rigid separation members, disposed through the slots provided in the sheet of material and between said lateral support members at their ends adjacent to said end members, for separating said lateral support members during use of the cot.
Claim 6
Dependent Claim
53 words
The cot frame as recited in claim 4, wherein said lateral support members are provided with longitudnally disposed, cylindrically shaped recesses, wherein said projecting members affixed to said coupling members are rectangular-shaped and diSposed perpendicular to said pivotable supporting members, and wherein said extension rods affixed to said pivotable supporting members are cylindrical-shaped.
Claim 7
Dependent Claim
97 words
The cot frame as recited in claim 5, wherein said pair of support legs comprises: a first, integrally formed, rigid support member, at least two, rigid, second support members, and a rigid mounting member, pivotably secured to said first member and affixed to the ends of said second support members, so that said second members are pivotable about said first member and the ends thereof abut the top and bottom surfaces of said first member and thereby limit the pivotable movement of said leg members, said pair of legs having an X-shaped configuration in their unfolded position.
Claim 8
Dependent Claim
84 words
The cot frame as recited in claim 6, wherein said end support members further comprise: at least one shoulder strap, for carrying the cot on the back of the user, said end support members being provided with a plurality of elongated slots in the surface thereof; and a plurality of securing members, having a T-shaped ends, coupled to the ends of said shoulder strap and disposed through said slots provided in said end support members, for securing said strap to said end support members.
Claim 9
Dependent Claim
38 words
The cot frame as recited in claim 6, further comprising an elongated, flat strap affixed to a side surface of one of said end support members, for carrying the cot frame by hand when the cot is disassembled.
Claim 10
Dependent Claim
148 words
The cot frame as recited in claim 6, further comprising: a plurality of semi-cylindrically shaped projecting slots, horizontally disposed parallel to the surface of said end support members, and protruding perpendicularly from the surface of said end support members; a U-shaped, cylindrical rod, having the ends thereof bent perpendicular to the vertically disposed portion of said rod and slidably disposed through said slots, for pivotably securing said rod to said end support members; a cylindrically shaped cross rod, affixed at its ends to the vertically disposed portions of said U-shaped rod parallel to the horizontal portion thereof; and at least two cylindrical rods, pivotably affixed at one end to said cross rod, and having the other ends thereof bent perpendicular to said rods and slidably disposed in said slots, for providing a collapsible rack attached to said end support frames for carrying supplies during carrying of the cot.
Claim 11
Dependent Claim

The cot frame as recited in claim 9, wherein said lateral support members are provided with cylindrically shaped recesses in their ends, and wherein said cot frame further comprises at least two pairs of vertically disposed, cylindrically shaped rods, having one of their ends bent perpendicular to said rod for slidable disposal into said recesses in said lateral support members, a plurality of horizontally disposed, cylindrically shaped rods affixed to the ends of said vertically disposed cylindrical rods for coupling said vertical rods together, a plurality of rectangular-shaped, elongated rods pivotably coupled together at their ends and affixed to said vertical rods, and a plurality of rectangular-shaped, cross-rib members, coupled to said rectangular-shaped rods, and disposed perpendicular thereto, for securing said rectangular-shaped rods together, thereby providing a tent-supporting structure for supporting a tent above the cot during use.
Claim 12
Dependent Claim
63 words
The cot frame as recited in claim 10, wherein said rectangular-shaped rods are pivotably connected by rivets affixed to their ends, and have rectangular-shaped, elongated slots in their ends which are offset when said support rods are aligned, and wherein said cross-rib members have T-shaped ends which are slidable through said slots when said slots are aligned, and interlock with said rectangular rods.
Claim 13
Dependent Claim
98 words
The cot frame as recited in claim 11, wherein said lateral support members are connected to said end support members by a plurality of L-shaped, hollow mounting members, said members having one end slidably disposed over the ends of said lateral support members and rigidly affixed thereto, and the other end fastened to said end members by a plurality of bolts and wing nuts, said mounting members and said lateral support members being disposed at an angle with respect to the horizontal plane of said end members so as to increase the load-bearing capability of the cot frame.
