The fitted sheet has an attached flat sheet. The fitted sheet is formed with a matching zipper for a mattress such that any bed sheet assembly with the appropriate attachment may be connected to any mattress with the matching half zipper. It should be clear to one skilled in the art that the instant embodiments do not relate to mattresses or cushions which do not utilize a fastener arrangement for covering the mattress. - Referring now to
FIG. 1 , a perspective view of abed assembly 10 is shown. Thebed assembly 10 includes amattress 12 and abed sheet assembly 20. Themattress 12 may comprise a foam mattress comprising one or more layers of foam, a coil spring mattress having a plurality of coil springs, or a combination of coil spring and foam defining the mattress cushion. - The
mattress 12 may include a top orupper surface 14, a bottom orlower surface 15, a pair oflong sides short sides sides upper surface 14 and thebottom surface 15. Thelong sides short sides - The
mattress 12 may also comprise afastener 30 extending about thesides fastener 30. Thefastener 30 may comprise various types of closure devices including, but not limited to,zipper 31, hook and loop, snaps, clips, or like embodiments. In the instant embodiment thefastener 30 may be embodied as azipper 31 which extends along each of the four sides 16-19. With thefastener 30 extending about theentire mattress 12, a fittedsheet 22 stays connected to themattress 12, even in the case an adjustable base is utilized. Thefastener 30 may extend about themattress 12 at a constant elevation relative to a reference surface or thefastener 30 may extend about themattress 12 at various elevations. In the instant embodiment depicted, the elevation along thelong sides short sides fastener 30 extends at a second, higher elevation. This arrangement of high and low elevations may also be reversed with respect to the long and short sides. - The
fastener 30 may comprise azipper 31 which is defined byteeth 33 of the fittedsheet 22 andteeth 34 of themattress 12 and at least one slider 37. While the term “teeth” is used throughout this description, the teeth are also synonymously known as, or interchangeably referred to as, “coils” by those skilled in the art. In the instant embodiment, the slider is depicted as afirst slider 37 a and asecond slider 37 b. Each set of teeth or coils 33, 34 on the fittedsheet 22 and themattress 12 has a specific number of teeth within a tolerance, according to some embodiments. With the specific teeth design of theillustrative zipper 31, thefastener 30 may be formed to receive a mattress, a mattress cover, or thebed sheet assembly 20. In some embodiments, a mattress cover 40 (FIG. 3 ) may additionally be connected to thefastener 30 and themattress cover 40 may include an additional fastener such that thebed sheet assembly 20 may be connected to themattress cover 40. Thus, with thefastener 30 of matched characteristics, a mattress cover, or abed sheet assembly 20, a protector 50 (described further herein) or a combination of any of these may be utilized. - The
bed sheet assembly 20 may comprise a fittedsheet 22 having a fastener 32, which cooperates withfastener 30. The fittedsheet 22 may extend over the upper peripheral edge of theupper surface 14 ofmattress 12 such that the fastener 32 may connect to themattress 12 or to amattress cover 40 having cooperating fastener. - In some embodiments the fitted
sheet 22 may have aperipheral edge 23 which may be at constant elevation about themattress 12, or in some embodiments theperipheral edge 23 may vary in elevation. The selection of theperipheral edge 23 type may be in concert with the design of themattress 12 or themattress cover 40 and therefore placement of the correspondingfastener 30 thereon. As previously described, thefastener 30 may vary in elevation and in such embodiment, theperipheral edge 23 of the fittedsheet 22 may likewise vary to followsuch fastener 30. - The fitted
sheet 22 may replace the prior art mattress cover and further differs from a mattress cover. Whereas prior art mattress covers may be formed of knit, high gram weight mattress ticking, the instant fittedsheet 22 may be form of woven cotton/polyester blend of low gram weight fabric. In some embodiments, thesheets 22 may be woven, for example plain weave, basket weave, satin weave, sateen weave, or twill weave. In some embodiments, thesheet 22 may also be a knit sheet, for non-limiting example, jersey stitch or rib stitch. Further, various fiber types may be utilized, including but not limited to, all natural, all synthetic, semi-synthetic such as viscose rayon, combinations or others. This list is non-exhaustive. The low gram weight fabric may be from about 20 gsm to about 400 gsm. - Along one side of the
mattress 12, and along one side or edge of the fittedsheet 22, aflat sheet 24 is connected to the fittedsheet 22. In the instant embodiment, theflat sheet 24 is connected to the fittedsheet 22 by aseam 25. Theseam 25 may be one or more seams which may be continuous or intermittent along corresponding edges of thesheets intermittent seams 25 along an edge or side may also allow improved venting and air flow near thefoot end 19 of thebed sheet assembly 20. - According to some embodiments, the
flat sheet 24 may be connected solely along one edge of the fittedsheet 22 so that the remaining three edges of thefiat sheet 24 are free relative to the fittedsheet 22. Further, the head end of theflat sheet 24 being loose allows for ease of entry and egress from the bed before and after sleep periods. During application of the fittedsheet 22, theflat sheet 24 is also applied, therefore to eliminate a step typical of bed making wherein the flat sheet applied above the fitted sheet must be applied separately. With the depicted embodiment, the head end of theflat sheet 24 is free to move and therefore need only be straightened during the bed-making process. - The
flat sheet 24 may be of a rectangular shape so that side edges and head/toe edges are at common elevation about themattress 12. However, in some embodiments, the elevation of the edges of theflat sheet 24 may vary, for example if it is desired to follow a varying elevation edge of the fittedsheet 22 andmattress 12 along thezipper 31. - The
flat sheet 24 may be also be a lightweight woven, for example cotton, polyester, or a combination, for non-limiting example. However, various materials may be utilized to form theflat sheet 24 and the instant description should not be considered limiting. Theflat sheet 24 may be the same or may differ from the fittedsheet 22. In some embodiments, but without limitation, theflat sheet 24 may be woven, for example plain weave, basket weave, satin weave, sateen weave, or twill weave. In some embodiments, thesheet 24 may also be a knit sheet, for non-limiting example, jersey stitch or rib stitch. Further, various fiber types may be utilized, including but not limited to, all natural, all synthetic, or semi-synthetic such as viscose rayon. The low gram weight fabric may be from about 20 gsm to about 400 gsm. - Referring now to
FIG. 2 , an exploded view of thebed assembly 10 is provided. Themattress 12 is shown at the bottom of the figure. - Disposed above the
mattress 12 is thebed sheet assembly 20. Thebed sheet assembly 20 is also shown in this view with anoptional protector 50 disposed beneath the fittedsheet 22. Theprotector 50 may be integrated with the fittedsheet 22 or may be fastened to thesheet 22. Theoptional protector 50 may be formed of various materials including, but not limited to, lightweight polyurethane backed polyester. Theprotector 50 may be sewn, adhered, applied, or otherwise affixed to alower surface 15 of the fittedsheet 22. Theprotector 50 may also serve as a material to prevent spills, stains, or other such undesirable damage to themattress 12. In some embodiments, theprotector 50 may also be incorporated by fasteners, for example by fastening to themattress 12. Alternatively, theprotector 50 may be fastened to the fittedsheet 22 above or, theprotector 50 may be fixed to the fittedsheet 22, for example sewn together or welded, wherein the fastening of theprotector 50 also connects the fittedsheet 22. - Above the
protector 50 is the fittedsheet 22 and the connectedflat sheet 24. The fittedsheet 22 may include theperipheral edge 23 defined by four sides of the fittedsheet 22. in some embodiments, two of the four sides are long sides and two of the sides are short sides. Disposed between the fittedsheet 22 and themattress 12 is thefastener 30, for non-limiting example a zipper. Thefastener 30 may be formed of separate halves either of which may be referred to as a fastener or fastener halves, each connected to one of themattress 12 or the fittedsheet 22, and at least one slider 37. In some embodiments, and for ease of description, the fastener halves may also be referred to as zipper tape or zipper teeth. Thezipper tape zipper tape sheet 22 and themattress 12, or a mattress cover (bottom portion or a top portion) so that the adjacent teeth or coils may be joined by the at least one slider 37. In some embodiments, the slider 37 may be two sliders which, in some embodiments are also two directional sliders. Thefasteners 30, 32 may be disposed along edges of the fittedsheet 22 or may be offset from the edges. With brief reference toFIG. 3 , in some embodiments, thezipper teeth sheet 22 and amattress cover 40, ifsuch mattress cover 40 is positioned on themattress 12 beneath the fitted sheet alternatively. - According to some embodiments, where the
fastener 30 is azipper 31, theteeth 33 of the half zipper of the fittedsheet 22 may be sized and have a count corresponding to the corresponding half zipper on themattress 12. This exact, or approximately, matching number of teeth may be referred to as a “matched teeth” arrangement. Accordingly, thebed sheet assembly 20 may be formed so as to be interchangeable with any mattress, or mattress cover, of the corresponding size. Thus the matched teeth number is dependent on the size of the mattress. Larger mattress sizes have more teeth due to a larger perimeter, while smaller mattress sizes have few teeth, due to the shorter perimeter dimension. Additionally, if the elevation of the fastener changes, this may change the length of the fastener. - The second or
flat sheet 24 is connected to the fittedsheet 22. Theflat sheet 24 may be connected along an edge of the fittedsheet 22 or may be connected along a side, for example spaced between the upper and lower edges of a short side. The instant embodiment provides thatseam 25 is disposed along a lower edge (feet end) of the fittedsheet 22 but may alternatively be disposed at the upper edge of the fittedsheet 22, adjacent to thetop surface 14, or alternatively may be connected at some place between the upper and lower edges. - Referring now to
FIG. 3 , an alternate embodiment is provided. The embodiment provides that amattress cover 40 may be utilized and provides alower zipper 42 which connects to a mating zipper of themattress 12. Themattress cover 40 may also comprise anupper mating zipper 44 which connects to thezipper 31 of the fittedsheet 22. Thus, the embodiment provides the additional use of themattress cover 40, rather than replacement of such. The embodiment further depicts an embodiment wherein thezipper 31 of the fittedsheet 22 is at a constant elevation, rather than varying as with the previous embodiment. The optionalprotective layer 50 is also shown and may be disposed beneath the fittedsheet 22. - Referring now to
FIG. 4 , a schematic view of the relationship of thezipper 31 includingteeth mattress 12 is provided.FIG. 4 depicts a schematic construction of the zipper teeth or coils 33 of the fittedsheet 22 that integrates with the existing zipper teeth or coils 34 of themattress 12, in order to describe the zipper length, teeth count and notching all of which are parameters that must be considered in ensure that zippers of fitted sheets will cooperate with zippers of themattress 12. Specifically, the perimeter path is schematically represented broken up into a plurality ofsegments 35 a-i. For ease of this description, the term teeth and teeth tape are used interchangeably however each teeth tape includes a plurality of individual teeth. Theteeth 34 of themattress 12 and theteeth 33 of the fittedsheet 22 are shown stretching across themattress 12. The extendingsegments 35 a-i are shown representing the perimeter length of themattress 12, corresponding to thezipper 30 length. The instant zip insheet assembly 20 is manufactured such that a first fitted sheet assembly may be replaced with a second fitted sheet assembly that is also connectable to themattress 12, without any hindrance due to teeth problems, fitting, or other mechanical issues which might preclude operation together. The instant zip insheet assembly 20 may be manufactured by one provider and the mattress by a different provider, but the products still cooperate and function together. Similarly, the products may be bought at different times and still cooperate together. - In order to provide this functionality, the view of
FIG. 4 provides a schematic layout of themattress 12. A perimeter path of the fastener length, represented by thezipper teeth 33 andteeth 34, or alternatively the path of travel of thesliders segments 35. Each of thesegments 35 a-35 i has a specific teeth count for a given size of tooth. For non-limiting example, theteeth segment 35 a-35 i. Further, theteeth segment 35. For example, in some embodiments anysingle segment 35 may have 1 tooth, and the overall tolerance for the fittedsheet 22teeth 33 relative to themattress 12teeth 34, or vice-versa, may be +1-2 teeth. - As shown in Table 1, four example mattress sizes are set forth, each with 8
segments 35 a-35 i (labeled 1-8 and End in the table). Eachsegment 35 a-35 i, of the perimeter has an example number of teeth and eachsegment 35 a-35 i is also shown with a tolerance for that segment. At the end of the table, a total number of teeth is provided as well as a total tolerance for theentire mattress 12. In this way, the number of teeth for themattress 12 may be matched with the number of teeth of thesheet assembly 20 to provide the matched arrangement. -

segments 35 a-35 i (labeled 1-8, and End) may also be associated with a linear measurement. Table 2 provides example measurements for eachsegment 35 a-35 i, for each of various bed sizes. This linear measurement in combination with each individual segment and a specific number of teeth may be used to manufacture and calibrate a matched zipper arrangement. Thus amattress zipper teeth 34 may he used with a zip insheet zipper teeth 33 despite the products being manufactured at different times and/or from different manufacturers. -

mattress 12 is dependent on the mattress size, twin, double, queen, king, etc. Thesegment 35 lengths may therefore vary with different sizes of mattress. Further, the number ofzipper teeth sheet assembly 20 may be installed and functional across various sizes of beds and even with various manufacturers of the parts involved in theassembly 10. - While several inventive embodiments have been described and illustrated herein, those of ordinary skill in the art will readily envision a variety of other means and/or structures for performing the function and/or obtaining the results and/or one or more of the advantages described herein, and each of such variations and/or modifications is deemed to be within the scope of the invent of embodiments described herein. More generally, those skilled in the art will readily appreciate that all parameters, dimensions, materials, and configurations described herein are meant to be exemplary and that the actual parameters, dimensions, materials, and/or configurations will depend upon the specific application or applications for which the inventive teachings is/are used. Those skilled in the art will recognize, or be able to ascertain using no more than routine experimentation, many equivalents to the specific inventive embodiments described herein. It is, therefore, to be understood that the foregoing embodiments are presented by way of example only and that, within the scope of the appended claims and equivalents thereto, inventive embodiments may be practiced otherwise than as specifically described and claimed. Inventive embodiments of the present disclosure are directed to each individual feature, system, article, material, kit, and/or method described herein. In addition, any combination of two or more such features, systems, articles, materials, kits, and/or methods, if such features, systems, articles, materials, kits, and/or methods are not mutually inconsistent, is included within the inventive scope of the present disclosure.
- All definitions, as defined and used herein, should be understood to control over dictionary definitions, definitions in documents incorporated by reference, and/or ordinary meanings of the defined terms. The indefinite articles “a” and “an,” as used herein in the specification and in the claims, unless clearly indicated to the contrary, should be understood to mean “at least one.” The phrase “and/or,” as used herein in the specification and in the claims, should be understood to mean “either or both” of the elements so conjoined, i.e., elements that are conjunctively present in some cases and disjunctively present in other cases.
- Multiple elements listed with “and/or” should be construed in the same fashion, i.e., “one or more” of the elements so conjoined. Other elements may optionally be present other than the elements specifically identified by the “and/or” clause, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, a reference to “A and/or B”, when used in conjunction with open-ended language such as “comprising” can refer, in one embodiment, to A only (optionally including elements other than B); in another embodiment, to B only (optionally including elements other than A); in yet another embodiment, to both A and B (optionally including other elements); etc.
- As used herein in the specification and in the claims, “or” should be understood to have the same meaning as “and/or” as defined above. For example, when separating items in a list, “or” or “and/or” shall be interpreted as being inclusive, i.e., the inclusion of at least one, but also including more than one, of a number or list of elements, and, optionally, additional unlisted items. Only terms clearly indicated to the contrary, such as “only one of” or “exactly one of,” or, when used in the claims, “consisting of,” will refer to the inclusion of exactly one element of a number or list of elements. In general, the term “or” as used herein shall only be interpreted as indicating exclusive alternatives (i.e. “one or the other hut not both”) when preceded by terms of exclusivity, such as “either,” “one of,” “only one of,” or “exactly one of.” “Consisting essentially of,” when used in the claims, shall have its ordinary meaning as used in the field of patent law.
- As used herein in the specification and in the claims, the phrase “at least one,” in reference to a list of one or more elements, should be understood to mean at least one element selected from any one or more of the elements in the list of elements, but not necessarily including at least one of each and every element specifically listed within the list of elements and not excluding any combinations of elements in the list of elements. This definition also allows that elements may optionally be present other than the elements specifically identified within the list of elements to which the phrase “at least one” refers, whether related or unrelated to those elements specifically identified. Thus, as a non-limiting example, “at least one of A and B” (or, equivalently, “at least one of A or B,” or, equivalently “at least one of A and/or B”) can refer, in one embodiment, to at least one, optionally including more than one, A, with no B present (and optionally including elements other than B); in another embodiment, to at least one, optionally including more than one, B, with no A present (and optionally including elements other than A); in yet another embodiment, to at least one, optionally including more than one, A, and at least one, optionally including more than one, B (and optionally including other elements); etc.
- It should also be understood that, unless clearly indicated to the contrary, in any methods claimed herein that include more than one step or act, the order of the steps or acts of the method is not necessarily limited to the order in which the steps or acts of the method are recited.
- In the claims, as well as in the specification above, all transitional phrases such as “comprising,” “including,” “carrying,” “having,” “containing.” “involving,” “holding,” “composed of,” and the like are to be understood to be open-ended, i.e., to mean including but not limited to, Only the transitional phrases “consisting of” and “consisting essentially of” shall be closed or semi-closed transitional phrases, respectively, as set forth in the United States Patent Office Manual of Patent Examining Procedures.
- The foregoing description of methods and embodiments has been presented for purposes of illustration. It is not intended to be exhaustive or to limit the invention to the precise steps and/or forms disclosed, and obviously many modifications and variations are possible in light of the above teaching. It is intended that the scope of the invention and all equivalents be defined by the claims appended hereto.
