Abstract
Abstract A portable cot and table which folds into a carrying case in which bedding or other equipment may be packed for travel and storage. Extensions may be added to the basic cot so that the length of the cot can be increased to accommodate the particular person using it. The legs are extensible so that the flat sleeping surface can be raised to the normal height of a table. Removable cups are provided for receiving each of the legs of the cot and the cups may be filled with a repellant or insecticide to prevent insects from crawling up the legs of the cot.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
184 words
In a portable cot that is collapsible into a carrying case; a pair of box sections, each presenting an open side and an opposite closed side and being pivotably connected to each other so that the two box sections can be pivoted away from each other to an open position with their closed sides in the same plane to present a contiguous flat surface that a person can lie on and said box sections can be pivoted toward each other to a closed position with their open sides facing each other to form an enclosure; a pair of legs pivotably supported by each of said box sections so that said legs can be pivoted into the box section for storage and may be pivoted outwardly therefrom to operating position wherein the four legs will support the two box sections above the ground with the open sides facing the ground and the closed sides presenting a flat contiguous top in a horizontal position; and clamping means rigidly locking said two box sections together in the open position to provide rigidity and stability to the cot.
Claim 2
Dependent Claim

Claim 3
Dependent Claim
48 words
A portable cot according to claim 1 including an extension; and means for mounting said extension to one of said box sections so that it presents a flat surface contiguous with the flat surface presented by its associated box section to selectively increase the length of the cot.
Claim 4
Dependent Claim
117 words
A portable cot according to claim 1 including a center leg adapted to support said cot at the juncture of said two box sections and wherein said clamping means comprises; a pair of cleats mounted on said box sections with one cleat being on one box section adjacent its edge and the other cleat being on the other box section adjacent its edge so that the two cleats cooperate; and a bracket mounted on the top of said center leg and being adapted to embrace both of said cleats and apply a force to them tending to draw the two box sections together while at the same time supporting them in a horizontal position above the ground.
Claim 5
Dependent Claim
79 words
A portable cot according to claim 3 including a tapered edge on each of said cleats so that the two cleats present two tapered edges inclined in opposite directions, and a pair of tapered surfaces on said bracket complementing the two tapered surfaces on said cleats so that as the bracket is moved onto the cleats the tapered surfaces on the brackets engage the tapered surfaces on the cleats to draw the two box sections together and secure them.
Claim 6
Dependent Claim
48 words
A portable cot according to claim 4 including an extension; and means for mounting said extension to one of said box sections so that it presents a flat surface contiguous with the flat surface presented by its associated box section to selectively increase the length of the cot.
Claim 7
Dependent Claim
165 words
A portable cot according to claim 5 wherein each of said box sections pivotally supports two legs so that said legs can be pivoted into the box section for storage and may be pivoted outwardly to operating position wherein the four legs will support the two box sections above the ground in a horizontal position; two removable center legs at the juncture of said two box sections with one center leg being disposed on each side of the cot to cooperate with said clamping means for providing additional rigidity and stability to the cot; removable cups for receiving the bottom end of each of said legs, a boss extending upwardly from the bottom of each of said cups and presenting a socket for receiving the bottom of one of the legs so that the leg may be inserted into the socket and the cup filled with a liquid repellant or insecticide to prevent pests from crawling up the leg to the occupant of the cot.
Claim 8
Dependent Claim
79 words
A portable cot according to claim 1 wherein each said legs comprises two tubular coaxial sections with one section telescoping into the other section so that the lengths of the legs can be adjusted to enable the flat surface to be supported at a height for sleeping on it or it may be raised to a height to enable it to be used as a table top, and means locking said two tubular sections together at the desired length.
Claim 9
Dependent Claim
177 words
In a portable cot that is collapsible into a carrying case; a pair of box sections, each presenting an open side and an opposite closed side; a hinge connecting said box sections together so that they can be pivoted away from each other to an open position so that the two closed sides present a contiguous top flat surface that a person can lie on and said box sections can be pivoted toward each other to a closed position with their open sides facing each other to form an enclosure; a plurality of legs that can be placed in operating position to support said box sections when they are in the open position with the open sides facing downwardly so that the opposite closed sides form a contiguous top side in a horizontal plane; a removable extension; and mounting means for mounting said extension to one of said box sections so that it presents a flat surface contiguous with the flat top surface presented by its associated box section to selectively increase the length of the cot.
Claim 10
Dependent Claim
177 words
In a portable cot that is collapsible into a carrying case; a pair of box sections, each presenting an open side and an opposite closed side; a hinge connecting said box sections together so that they can be pivoted away from each other to an open position so that the two closed sides present a contiguous top flat surface that a person can lie on and said box sections can be pivoted toward each other to a closed position with their open sides facing each other to form an enclosure; a plurality of legs that can be placed in operating position to support said box sections when they are in the open position with the open sides facing downwardly so that the opposite closed sides form a contiguous top side in a horizontal plane; a removable extension; and mounting means for mounting said extension to one of said box sections so that it presents a flat surface contiguous with the flat top surface presented by its associated box section to selectively increase the length of the cot.
Claim 11
Dependent Claim
78 words
A portable cot according to claim 8 wherein said box sections are formed of a plurality of structural members and said mounting means comprises a plurality of L shaped members each having one leg of the L secured to said extension and the other leg of the L depending downwardly therefrom through an opening in the flat surface of said box section into engagement with a structural member of the box section for supporting the extension in position.
Claim 12
Dependent Claim
85 words
A portable cot according to claim 9 including a support depending from the underside of said extension in alignment with said L shaped member and presenting a surface spaced from the depending leg of said L shaped member so that said structural member fits between them whereby said support is located on one side of said structural member and the depending leg of said L shaped member is located on the other side of said structural member to firmly support the extension in operating position.
Claim 13
Dependent Claim
80 words
A portable cot according to claim 8 wherein each of said legs comprises two tubular coaxial sections with one section telescoping into the other section so that the lengths of the legs can be adjusted to enable the flat surface to be supported at a height for sleeping on it or it may be raised to a height to enable it to be used as a table top, and means locking said two tubular sections together at the desired length.
