Sheet assembly for use as a multipurpose tote bag

Claim 2

A sheet assembly for use as a multipurpose tote bag, comprising: two layers of waterproof material partially sewn together to form a two-piece sheet formation with an unsewn opening at a top portion, wherein said two-piece sheet formation is adapted to be folded, in a first folding operation in an overlapping manner along vertical and horizontal axes, from predetermined folding points, to form a folded sheet formation in which the folded portions form a top opening and two inside portions of said tote bag, and wherein the folded sheet formation is further foldable in a second folding operation along a center folding axis forming the bottom of said tote bag and is adaptable for forming the tote bag by means of two pairs of fastener attachments sewn in parallel along the vertical axes, with the mating parts of each fastener attachment sewn in parallel and extending from the bottom to the top opening of said tote bag, said two-piece sheet formation having unsewn openings at top and bottom portions.

Claim 3

A sheet assembly for use as a multipurpose tote bag as in claim 1, wherein an additional sheet of material is sewn onto a portion of the layer of material forming a side of said tote bag.

Claim 4

A sheet assembly for use as a multipurpose tote bag as in claim 2, wherein an additional sheet of material is sewn onto a portion of the layer of material forming a side of said tote bag.

Claim 5

A sheet assembly for use as a multipurpose tote bag as in claim 1, wherein the fastener attachments are attached along one set of said vertical and horizontal axis via auxiliary sheets, said auxiliary sheets forming additional side portions of said tote bag.

Claim 6

A sheet assembly for use as a multipurpose tote bag as in claim 4, wherein an additional sheet of material is sewn onto a portion of the layer of material forming a side of said tote bag.

Claim 7

A sheet assembly for use as a multipurpose tote bag as in claim 1, wherein at least one pocket is formed on the outside portion of said tote bag closest to the top of the sheet assembly.

Claim 8

A sheet assembly for use as a multipurpose tote bag as in claim 6, wherein an additional sheet of material is sewn onto a portion of the layer of material forming a side of said tote bag.

Claim 9

A sheet assembly for use in the forms of a tote bag, a beach mat or ground cover, a rain shelter, and a portable dressing closet, comprising: front and back rectangular sheets of waterproof material having substantially equal length and width dimensions, one or more additional sheets of waterproof material of smaller dimensions than said front and back sheets, two fastener attachments each comprising two mating parts, and a pair of handles; wherein said front and back rectangular sheets are attached to each other along both lengthwise side edges, and are partially attached to each other along a top widthwise edge, with an opening in the middle portion of the top edge; said one or more additional sheets are attached to the top sheet within an area bounded by the width of the front sheet and that portion of the length of the front sheet between a horizontal center folding axis bisecting the front sheet across its width and a second horizontal axis located about one-half the distance between said center folding axis and the top edge of the front sheet, with openings to form one or more pockets; said fastener attachments are attached to the front sheet in an alignment parallel to each other and to the lengthwise side edges of the front sheet, and the mating parts of each fastener attachment are attached to the front sheet on opposite sides of the horizontal center folding axis; said handles are attached to the front sheet, with a gripping portion of one handle extending from the front sheet at a position located above the center folding axis and about one-half the distance between the center folding axis and the top edge of the front sheet and about one-half the width of the front sheet, and the gripping portion of the other handle being symmetrically located at a position below the center folding axis; and further wherein said sheet assembly, serviceable in an unfolded disposition for use as a beach mat or ground cover, a rain shelter, and a portable dressing closet, is adaptable to be reversibly converted to a tote bag by: folding the sheet assembly inwardly along two vertical axes adjacent to the parallel fastener attachments such that the front sheet forms the exterior of the once-folded assembly; folding the once-folded sheet assembly inwardly again along two horizontal axes located about one-half the distance, above and below, respectively, the horizontal center folding axis; folding the twice-folded sheet assembly inwardly about the horizontal center folding axis such that the mating parts of the fastener attachments are adjacent one another and are mateable to complete conversion of the sheet assembly to use as a tote bag.

Claim 10

A sheet assembly for use in the forms of a tote bag, a beach mat or ground cover, a rain shelter, and a portable dressing closet, comprising: front and back rectangular sheets of waterproof material having substantially equal length and width dimensions, one or more additional sheets of waterproof material of smaller dimensions than said front and back sheets, two fastener attachments each comprising two mating parts, and a pair of handles; wherein said front and back rectangular sheets are attached to each other along both lengthwise side edges, and are partially attached to each other along a top widthwise edge, with an opening in the middle portion of the top edge; said one or more additional sheets are attached to the top sheet within an area bounded by the width of the front sheet and that portion of the length of the front sheet between a horizontal center folding axis bisecting the front sheet across its width and a second horizontal axis located about one-half the distance between said center folding axis and the top edge of the front sheet, with openings to form one or more pockets; said fastener attachments are attached to the front sheet in an alignment parallel to each other and to the lengthwise side edges of the front sheet, and the mating parts of each fastener attachment are attached to the front sheet on opposite sides of the horizontal center folding axis; said handles are attached to the front sheet, with a gripping portion of one handle extending from the front sheet at a position located above the center folding axis and about one-half the distance between the center folding axis and the top edge of the front sheet and about one-half the width of the front sheet, and the gripping portion of the other handle being symmetrically located at a position below the center folding axis; and further wherein said sheet assembly, serviceable in an unfolded disposition for use as a beach mat or ground cover, a rain shelter, and a portable dressing closet, is adaptable to be reversibly converted to a tote bag by: folding the sheet assembly inwardly along two vertical axes adjacent to the parallel fastener attachments such that the front sheet forms the exterior of the once-folded assembly; folding the once-folded sheet assembly inwardly again along two horizontal axes located about one-half the distance, above and below, respectively, the horizontal center folding axis; folding the twice-folded sheet assembly inwardly about the horizontal center folding axis such that the mating parts of the fastener attachments are adjacent one another and are mateable to complete conversion of the sheet assembly to use as a tote bag.

Claim 11

A sheet assembly as in claim 8 wherein at least one of the mating parts of each of the fastener attachments is attached to the front sheet by means of a piece of material, such that said piece of material forms a side of the tote bag when the sheet assembly is adapted for use as a tote bag.

Claim 12

A sheet assembly as in claim 8 wherein at least one pocket is adapted to be closed and opened by means of a fastener attachment positioned adjacent said pocket on the front sheet and a fastener attachment positioned at the opening between the front sheet and the additional sheet forming the pocket.
