BACKGROUND OF INVENTION
Conventional fitted bed sheets are not easy to fold and store, especially, bigger sized sheets such as queen and king sheets. The purpose of this invention is so that bed sheets can be easily folded after being washed and dried to store. The design of this sheet allows the sheet to be convertible from a flat sheet to a fitted sheet and is also reversible which creates an ornamental design—all by releasing zippers, buttons, elastics or other similar mechanism for the same purpose. There are no other products on the market that have this kind of complete multi function bed sheet for fitted or flat sheets.
BRIEF SUMMARY OF THE INVENTION
This invention is a bed sheet that is convertible and reversible from a flat bed sheet into a fitted bed sheet or vice versa. This design provides four different benefits. First, it is much easier to fold and store than traditional fitted sheets. Second, it has an option to make a bed without having the bed sheet to tuck in the bottom corners to keep the sheet in place and stay tight on a mattress. There is still the option to use this fitted sheet in a traditional way as well by using the releasable elastics installed onto the corners of the sheet. Third, the bed sheet is reversible and neither side looks inside out which shows a complete natural look of the bed sheet and the ornamental design. Fourth, the corner pieces of the zippered area can be an option to make detachable.

FIG. 1: Main bed sheet; 1 has an added center sheet on the front sheet; 1-1, optional, Expansion of the edges of the bed sheet; 2,3,4 and 5. The width can be modified depending on personal preferences. Opened zippers; 6, 7, 8, 9, 10, 11, 12 and 13. Separate fabrics can be sewn over the edges (FIG. 15) with desirable lengths starting from the zipper (recommend 12 to 24 inches); 14, 15, 16, 17, 18, 19, 20 and 21. The elastic can be inserted between the expanded edges before being sewn over the elastic onto the expanded edges (FIG. 13, FIG. 14). The beginning of the inserted elastic can be attached between the two elements and leave the rest of the elastic loose in order to fasten or release; 22, 23, 24, 25, 26, 27, 28 and 29. Buttons can be sewn onto the other end of the elastic to be fastened or released to make the fitted bed sheet or to make it easy to fold it to store. These buttons be can be replaced with other types of mechanisms to fasten and release elastics such as velcro, hooks, different types of snap buttons; 30,31,32,33,34,35,36 and 37. The end piece of the elastic is used a pull to fasten or to make the fitted bed sheet; 38, 39, 40 and 41. Pieces of the fabric are used to cover the top of the zipper to protect it from being damaged by washing and drying and hiding the zipper cap and puller; 42,43,44 and 45. A piece of velcro has been attached to the opposite side of the velcro to connect to 46,47,48 and 49 securely. The zippers stay on and hide the zipper cap and puller. This velcro can be replaced by other mechanisms such as hooks, buttons or any type of snap buttons. Pieces of 46,47,48 and 49 can be connected to 42,43,44 and 45 on the opposite side of the velcro 50,51,52 and 53. Stitches connecting the expansion fabric to the main bed sheet 54,55.56 and 57 and the other side of the zippers 58,59,60 and 61. Additional pieces of the fabric on the bottom two corners help stabilize the shape of the loose fabric help with the ornamental design look. The large flat bed sheet can be folded in half easily in either direction utilizing an interlocking system with the connector 44a to 49a and 47a to 42a, or 44a to 47a and 49a to 42a to secure both touching side stays together.



DETAILED DESCRIPTION OF THE INVENTION
This bed sheet is designed to resolve the problems with folding fitted bed sheets, to make the bed easier and make it comfortable when you sleep. The entire flat bed sheet remains intact with zippers sewn at 90 degrees facing the corners of the fabric and using releasable elastics that are attached onto the expansion area next to the zippers. The edges of each corner must be cut shorter to avoid touching the floor with different shapes or can be left without cutting depending on personal preferences. This method can be done with the bottom two corners only or all four corners. The zipper can be replaced by any alternative method such as buttons, hooks, velcro, snap buttons, or any other locking and attachment methods. The attached releasable elastics are optional to use to make it fit under the mattress to make the bed sheet tight to the mattress or leave them loose for an ornamental design and easier method making the bed. A method of pulling upward the bottom two corners of the bed sheet slightly makes a room for feet when sleep.
The expansion of the edges for the attachment of the releasable elastic around the bed sheet gives an additional benefit for an option to choose a different colored fabric with equal width for an ornamental design and to balance the thickness of the edges resulted from the releasable elastic installation. It gives an option to use the design and coordination with colors of other bedding sets such as pillowcases and comforters, etc.
The top of the zippers will be covered with a small piece of fabric, elastic, or other material to cover and protect a zipper pull from possible damage due to washing and drying. The bottom part of the zipper will be covered by putting small releasable pieces of connectors on each side of the zipper such as velcro, button, hooks, snap buttons, or any other attachment method to protect zippers from washing and drying and secure the zipper to stay closed tight. In other words, covering the top of the zipper protects the zipper caps and pullers when the zipper is unzipped and hides the zipper caps and pullers. The method of connecting the bottom two pieces of zippers from each side together locks the bottom area of each corners to stay fit and tight to the mattress when it is in use. The other benefit of the said method is that the connectors can be utilized connecting either opposite side of the connector to fold and lock both touching side during the folding stage.
Additional fabric can be attached diagonally with isosceles triangle shape in the center part between the open zippers on the loose side of the corner on the outer skirt to keep the fabric on the isosceles triangle shape for the ornamental design look.
An additional piece of fabric, the same dimension of the top of the mattress surface, can be sewn onto the center of the back side of the fabric to make it a complete view of the reversible bed sheet which is optional.
This invention is not limited to bed sheets only and this can be utilized for table covers, couch covers, or any other covers.
