CROSS-REFERENCE TO RELATED APPLICATIONS
The present application claims benefit of and priority from a U.S. Provisional Patent Application No. 61/637,138 filed on Apr. 23, 2012 and titled “Bedding Article”. The disclosure of the above-mentioned provisional application is incorporated herein by reference in its entirety for all purposes.
- BACKGROUND ART
The present invention relates to sheets and blankets and, more particularly, to a fabric blanket construction adapted to cover two individuals in the same bed such as to allow these individuals to wrap into the blanket individually, without disturbing each other.
- SUMMARY OF THE INVENTION
Couples sleeping or resting in the same bed usually do not have too much choice as to a cover that they use. Normally, both persons are sharing the same cover (such as a sheet or blanket), in which case they often engage in a competition of who is using the blanket more. This problem is particularly acute with regard to being able to wrap oneself into a blanket as a cocoon. Alternatively, the sleepers have to use individual blankets, in which case the feeling of sleeping together is not as appealing. Accordingly, there exists a need in an article of manufacture that can be adapted as a bedding article providing opportunity to an individual sleeper to wrap him or herself in it, while retaining a sensitivity of a single cover for the couple of sleepers sharing the bed.
Embodiments of the present invention provide an article of manufacture that includes a first foldable sheet having a perimeter that defines a concave polygon and a first interior angle; a length defined by a longitudinal side of such polygon; and a first width defined by two corners of such polygon and at least one side connecting these two corners. The longitudinal side is generally transverse to one or more sides associated with the first width. When the first width is defined by two or more sides, such sides of the polygon, these sides are optionally oblique to one another. The interior angle of the polygon differs from 180 degrees and, in a specific implementation, is about 360 degrees. Alternatively or in addition, the concave polygon formed by the perimeter of the embodiment is symmetrical with respect to a bisector line bisecting the first interior angle, which bisector is optionally oblique with respect to the longitudinal side of the polygon. The article may have a second width defined by second and third sides of the polygon, which are optionally symmetrical to one another with respect to the bisector of the interior angle and, alternatively or in addition, are oblique to one another. In a specific embodiment, the article additionally combines a second foldable sheet (optionally removably) affixed to the first foldable sheet along a side of the polygon that defines the first interior angle. An embodiment of the article of manufacture can be adapted as a bedding article dimensioned to cover at least a coupled of individuals sharing a bed and to allow each of the individuals wrap him/herself in a portion of the article adjacent to the interior angle of the polygon.
Embodiments of the invention additionally provide an article of manufacture comprising a first foldable sheet having corresponding first length, first width, and first corner; and a second foldable sheet having corresponding second length, second width, and second corner. Such sheets are affixed to one another at the first and second corners to define a portion of the first foldable sheet that overlaps the second foldable sheet. Such portion of overlap extends along the second length of the second sheet when the bedding article is spread out. Such overlapping portion of the first foldable sheet is optionally detached from a portion of the second foldable sheet that it folds over or overlaps. The first and second sheets are not attached to one another along at least a part of the overlapping portion. The overlapping portion optionally extends the second corner to a next corner of the second sheet or substantially along the whole length of the second sheet. The first sheet may include means for removably affixing of the corners of the first and second sheets.
In a specific embodiments, the first and second sheets are substantially coextensive, in either length, or width, or both length and width. In another implementation, the second width is larger than the first width. An article of manufacture is optionally adapted for use as a bedding article.
BRIEF DESCRIPTION OF THE DRAWINGS
Embodiments of the invention additionally provide a method for fabrication of a bedding article. The method includes positioning a first foldable sheet (having a first length, first width and first corner with respect) to a second foldable sheet (having a second length, second width and second corner) such as to partially overlap the first and second foldable sheets to form an overlap area extending from the first and second corners along the first length; and affixing the first and second foldable sheets to one another in a first portion of the overlap area that corresponds to the first and second corners such as to keep the first and second foldable sheets disattached in a second portion of the overlap area.

Referring now to FIG. 1, an embodiment of a bedding article is shown in top view, which includes a foldable sheet 100 (made of fabric, for example) a perimeter 110 of which defines a concave polygon having an interior angle A. The sheer 100 has a length defined by a longitudinal side 114 of the polygon. The sheet 100 also has a first width 116 defined by the first and second corners 120, 122 and at least one side of the polygon that connects the corners 120, 122. The width 116 and the length 114 are defined such as to be associated with directions that are substantially transverse to one another. An interior angle A differs from 180 degrees and, generally, is formed by sides 130, 132 of the polygon 110 that are comparable in length with that polygon side which defines the length 114. As shown in FIG. 1, the interior angle is A greater than 180 degrees and lower than 360 degrees. FIG. 2 illustrates a related embodiment 200, in which the width 116 is defined by two polygon sides 210, 212 that are oblique to one another and define a second interior angle B. The presence of the first internal angle A specifies two sub-portions I and II of the sheets 100, 200 that can be considered to be flaps of a corresponding embodiment extending substantially along the whole length 114 from a bottom of the corresponding sheet (associated with the width 116 and, in practice, adapted to cover legs of the users) to a top of the sheet that is opposite to the bottom and defined by sides 140, 142. In practice, a couple of sleepers uses an embodiment of the bedding article to cover themselves together, as a couple, while having a freedom individually cover with or wrap into a flap used to a given sleeper. Such bedding article may optionally include additional fixtures such as, for example, means for affixing the article to a bed or recliner such as loops, buttons and/or buttons holes and straps (if required) or, for example, pockets.
Generally, geometrical extents of the sub-portions I, II that are defined transversely to the length 114 of a bedding article may be not equal. In the embodiment 100, for example, such inequality of dimensions generally corresponds to the sides 140, 142 having different lengths as compared to one another. In the embodiment 200 such inequality of dimensions generally corresponds to the sides 210, 212 having different lengths, as compared to one another. In either case, a corresponding implementation of the bedding article defines an additional width parameter corresponding to the top portion of the polygon, and sub-portions or flaps of the polygon are appropriately dimensioned to accommodate the needs of a user. A longitudinal side of the polygon defining its length 114 can be oblique with respect to a top side of the polygon (such as the side 140 or the side 142). This situation is illustrated schematically in FIG. 3A, showing the top side 140 and the longitudinal side 310 forming an interior angle C<90 degrees; and in FIG. 3B, showing the top side 140 and the side 310 forming an interior angle D>90 degrees.
FIGS. 4A, 4B illustrate embodiments 400, 404 each of which has a corresponding perimeter defining a concave polygon that is symmetric with respect to a bisector 410 of the interior angle A. In a specific embodiment, the sides 210, 212 are symmetric to one another with respect to the bisector 410.
FIGS. 5A, 5B show schematically related embodiments 500, 510, in which the corresponding articles of manufacture of the invention are formed by a first foldable sheet 520 and a second foldable sheet 530 affixed to the sheet 520 along its side such as to define the interior angle A. Preferably, corners and/or corner areas 540 of the first and second sheets 520, 530 corresponding to the bottom portion of the articles 500, 510 are permanently affixed to one another (for example, appropriately sawn or seamed together).
As shown in related embodiments 600, 604 of FIGS. 6A, 6B, the sheets 520, 530 are (optionally removably) connected at a bottom area 540 (which includes corresponding corners of the sheets) and overlapped with one another such as to define a portion 610 of the sheet 520 that overlaps or folds over the sheet 530 along the length of the sheet 530 when the bedding article 600 is spread out. Such overlapping portion 610 may run along substantially the whole length of the sheet 530, for example when the sheet 530 is dimensioned to be rectangular. In this case, the overlapping portion may be rectangular in shape (as shown in FIG. 6B) or trapezoidal (not shown).
FIG. 8 illustrates an embodiment 800 (such as any of the embodiments described above) that is additionally equipped with a means 808 for releasably joining the flaps 810, 812 together. As shown, the means 808 include the snap features disposed along the edges of the flaps 810, 812, but can generally include different means of attachment facilitating the temporary or reversible cooperation between the flaps. Such cooperation between the first and second flaps can be not only removable (for example, via an attachments means such as, for example, Velcro or buttons) but also, optionally, reconfigurable.
In accordance with examples of embodiments, described above a single article of manufacture is provided that can be adapted as a bedding article for individual cover and/or wrapping of individuals sharing a bed or recliner. It will be understood by those of ordinary skill in the art that modifications to, and variations of, the illustrated embodiments may be made without departing from the inventive concepts disclosed herein. For example, an article of manufacture may include a sheet the perimeter of which defines a concave polygon having more that one interior angle that is greater than 180 degrees (and, in particular, about 360 degrees) and that accordingly specifies more than two flap sub-portions facilitating the use of the article by more than two people at once. A schematic of such implementation is shown in FIG. 7. Furthermore, disclosed aspects, or portions of these aspects, may be combined in ways not listed above. An embodiments of a bedding article of the invention configured as a blanket may have a substantial thickness to accommodate a heat-conserving layer therein. Accordingly, the invention should not be viewed as being limited to the disclosed embodiment(s).
