BED SHEET SYSTEM

FIELD OF THE INVENTION

Embodiments of the present invention relate generally to a bedding system. More specifically, the bedding system includes a retention element retained on a bed mattress. A first bedding element is removably interconnectable to the retention element. The bedding system may optionally include a second bedding element removably interconnectable to the first bedding element. In this manner, the first and second bedding elements may be removably interconnected to the mattress by the retention element.

BACKGROUND OF THE INVENTION

When a bed is slept in, sheets become loose and blankets may slide off of the bed and end up on the floor. Because of this, the occupant's sleep may be interrupted to rearrange the sheets or retrieve the blanket from the floor. This is particularly a problem during non-domestic sleep experiences for beds located in recreational vehicles, campers, and tents.

Additionally, making up the bed after it has been slept in is often difficult and time consuming because sheets and blankets frequently become disarrayed due to occupant movement. To change or straighten the sheets they must often be pulled over (in the case of a fitted sheet) and/or tucked underneath the mattress (in the case of a flat sheet). The mattress weight and design and bed frame design can all contribute to difficulty in making up the bed or changing the sheets. External factors, such as bed rails, furniture around the bed, and walls close to the bed, may further increase the difficulty of making up the bed or changing the sheet by limiting access to the bed.

Thus, there is a need for a bedding system that improves both sheet function as well as bed covers to create ease of changing sheets, ease of making the bed, and a more comfortable sleep experience.

SUMMARY OF THE INVENTION

Some embodiments of the present invention provide a bedding system for a mattress that is easy to change and stays securely on the mattress. The bedding system generally comprises a retention element and a first bedding element selectively interconnected to the retention element. Optionally, a second bedding element may be interconnected to the first bedding element. The bedding system also improves safety for babies and young children by mitigating entrapment hazards, and limits corners from popping off during placement on the mattress or during sleep.

One aspect of the bedding system is that it is easy to fold. The bedding system may be washed and dried as one piece with its components interconnected. Alternatively, one or more portions of the bedding system may be washed and dried separately.

It is another aspect of embodiments of the present invention to provide a retention element sized to be retained on a mattress. The retention element includes at least one part of a closure to receive a first bedding element. In one embodiment, the retention element does not contact a bottom surface portion of the mattress.

DETAILED DESCRIPTION

The present invention has significant benefits across a broad spectrum of endeavors. It is the Applicant's intent that this specification and the claims appended hereto be accorded a breadth in keeping with the scope and spirit of the invention being disclosed despite what might appear to be limiting language imposed by the requirements of referring to the specific examples disclosed. To acquaint persons skilled in the pertinent arts most closely related to the present invention, a preferred embodiment that illustrates the best mode now contemplated for putting the invention into practice is described herein by, and with reference to, the annexed drawings that form a part of the specification. The exemplary embodiment is described in detail without attempting to describe all of the various forms and modifications in which the invention might be embodied. As such, the embodiments described herein are illustrative, and as will become apparent to those skilled in the arts, may be modified in numerous ways within the scope and spirit of the invention.

Referring now to FIGS. 1-5, a bedding system 12 of an embodiment of the present invention is illustrated. The bedding system 12 generally comprises a retention element 14, a first bedding element 30, and a second bedding element 70.

The retention element 14 generally includes a first portion 27A of a first two-part closure 26 and a first longitudinal panel 16A connected to a second longitudinal panel 16B by first and second transverse panels 18A, 18B. In one embodiment, the retention element 14 has a generally rectangular shape.

The retention element 14 generally has a size and shape selected to fit a mattress 2 of a bed. More specifically, the horizontal cross-sectional shape of the retention element 14 generally corresponds to the horizontal cross-sectional shape of the mattress 2. Additionally, the length and width of the retention element 14 are about equal to, or slightly greater than, the corresponding length and width of the mattress 2.

The first and second longitudinal panels 16A, 16B are adapted to contact at least a portion of respective first and second longitudinal sidewalls 4A, 4B of the mattress 2 when the retention element 14 is positioned on the mattress 2. Similarly, the first and second transverse panels 18 contact at least a portion of respective first and second transverse sidewalls 6 of the mattress when the retention element is on the mattress 2. In one embodiment, the panels 16-18 of the retention element 14 substantially cover corresponding sidewalls 4-6 of the mattress 2 as generally illustrated in FIG. 1B. In another embodiment, the panels 16-18 of the retention element 14 contact at least a portion of the top portion 8 of the mattress 2. Optionally, an elastic material or other biasing element may be positioned proximate to one or more of an upper peripheral edge 20 and a lower peripheral edge 22 of one or more of the panels 16-18 to decrease at least one of the length and the width of the retention element 14 with respect to the mattress 2.

In one embodiment, the retention element 14 optionally includes a bottom panel 24 adapted to at least partially contact a bottom portion 10 of the mattress 2. In one embodiment, the bottom panel 24 is continuous between the first and second longitudinal panels 16A, 16B and between the first and second transverse panels 18A, 18B. In this manner, the optional bottom panel 24 may cover all of the bottom portion 10 of the mattress. Alternatively, the bottom panel 24 is discontinuous such that there are apertures in the bottom panel 24 and only some of the bottom portion 10 of the mattress is covered.

Optionally, the first closure portion 27A may extend substantially continuously around the retention element. Accordingly, in one embodiment, each of the panels 16A, 16B, 18A, 18B includes a portion of the first closure portion 27A. Alternatively, one or more of the panels 16A, 16B, 18A, 18B may be devoid of the first closure portion 27A. Thus, in another embodiment, the first closure portion 27A is only included on the first and second longitudinal panels 16A, 16B. In one embodiment, the first closure portion 27A is spaced from an upper peripheral edge 20 of the retention element 14. In another embodiment, the first closure portion 27A is positioned proximate to, or at, the edge 20 of the retention element 14. In one embodiment, the first closure portion 27A is positioned proximate to an upper peripheral edge 20 of the retention element 14. In another embodiment, the first closure portion 27A is substantially parallel to the upper peripheral edge 20. However, one of skill in the art will appreciate that the first closure portion 27A may be arranged at any location of the retention element. Accordingly, in another embodiment, the first closure portion 27A may alternatively be spaced from the upper peripheral edge, or closer to the lower peripheral edge 22 than to the upper peripheral edge.

Referring now to FIG. 1C, the retention element 14A may optionally be interconnected to the mattress 2A with one or more fasteners or closures. One of skill in the art will appreciate that any type of closure or fastener may be used to interconnect any embodiment of retention element of the present disclosure to the mattress. For example, as illustrated in FIG. 1C, buttons 64 positioned on the mattress 2A may engage button holes 60 formed in the retention element 14A. Alternatively, the retention element 14A may include buttons that engage button loops or button holes formed on the mattress 2A. In another embodiment, one or more of snaps, buttons, a zipper, and a hook and loop fastener are used to interconnect the retention element 14A to the mattress 2A.

The first bedding element 30 generally includes an exterior surface 32 opposite to an interior surface 34, and a first peripheral edge 36A opposite to a second peripheral edge 36B. A second portion 27B of the first closure 26 is interconnected to the interior surface 34 to align with the first portion 27A of the first closure 26. In this manner, the second portion 27B is interconnectable to the first portion 27A of the first closure 26. In one embodiment, the first two-part closure 26 is a zipper. A pull for the first closure 26 may be associated with the second closure portion 27B. Alternatively, the zipper pull may be associated with the first closure portion 27A.

In one embodiment, the first bedding element 30 has at least one of a length that is greater than a length of the longitudinal panels 16 and a width that is greater than a length of the first and second transverse panels 18 of the retention element 14. Accordingly, when the first bedding element 30 is interconnected to the retention element 14, the first and second peripheral edges 36A, 36B drape at least partially down over the first and second longitudinal sidewalls 4A, 4B of the mattress as generally illustrated in FIG. 1B.

Optionally, referring now to FIG. 2, the first bedding element 30 comprises first and second panels 52, 54 that extend from a medial panel 50. In one embodiment, the first and second panels 52, 54 extend about 1 inch from the medial panel 50; however, one of skill in the art will appreciate that the first and second panels 52A, 52B may be of any predetermined width. In another embodiment, the first and second panels extend between about 0.5 inch and about 8 inches from the medial panel 50. Slots 56 may be formed proximate to corners of the first bedding element 30 such that the first and second panels 52, 54 may drape at least partially down against the sidewalls 4 of the mattress. Optionally, a closure, such as but not limited to, a zipper, a snap, or a tie may be interconnected to adjacent sides of one or more of the slots 56. In this manner, the slots 56 may be at least partially closed by the closure.

The first bedding element 30 also includes a first portion 43A of a second two-part closure 42 and a first portion 45A of a third two-part closure 44. In one embodiment, the first portions 43A, 45A are interconnected to the first bedding element at a position substantially parallel to a longitudinal axis 40 of the first bedding element 30 that is substantially equally spaced from the first and second peripheral edges 36A, 36B. Optionally, the first portions 43A, 45A are positioned on the first and second panels 52, 54 respectively. In one embodiment, the first portions 43A, 45A are positioned closer to the respective first and second peripheral edges 36A, 36B than the second portion 27B of the first closure 26. In another embodiment, the first closure 26 is arranged such that the first and second portions 27A, 27B are not between the top portion 8 of the mattress 2 and the interior surface portion 34 of the first bedding element 30 when the first bedding element 30 is positioned on the mattress 2.

Preferably, the first portions 43A, 45A extend along at least a portion of a length of each of the first and second peripheral edges 36A, 36B as illustrated in FIG. 2. For example, in one embodiment, the first portions 43A, 45A of the second and third closures 42, 44 extend up to about one-third of the length of edges 36A, 36B. Alternatively, the first portions 43A, 45A may extend up to about one-half of the length of edges 36. However, in another embodiment, the first portions 43A, 45A have a length substantially equal to the length of the first and second longitudinal sidewalls 4A, 4B of the mattress 2.

In one embodiment, illustrated in FIGS. 2 and 5A, the first closure portions 43A, 45A of the second and third closures 42, 44 are interconnected to the interior surface 34 of the first bedding element 30. Alternatively, the first closure portions 43A, 45A may optionally be interconnected to the exterior surface 32 of the first bedding element 30A as illustrated in FIG. 5B. FIG. 5B also illustrates an embodiment of the first bedding element 30A that is wider than the mattress 2 such that the first and second panels 52A, 52B drape downwardly proximate to the longitudinal panels 16A, 16B of the retention element.

Additionally, the first bedding element 30 may optionally include a first portion 47A of a fourth two-part closure 46. The first portion 47A is preferably arranged substantially perpendicular to the longitudinal axis 40 proximate to a third peripheral edge 38A.

Optionally, the first bedding element 30 may be interconnected directly to the mattress 2 without the use of the retention element 14. Accordingly, one embodiment, the first bedding element 30 includes a second portion 27B of a first two-part closure 26 that interconnects to a first portion 27A of the first closure 26 affixed to the mattress 2. In one embodiment, the first portion 27A is positioned on at least one of the longitudinal sidewalls 4 of the mattress. Optionally, in another embodiment, the first bedding element 30 is interconnected to the mattress 4 by a plurality of buttons or snaps.

In one embodiment, the first bedding element 30 is a sheet. The first bedding element 30 may be formed of any suitable material. In one embodiment, the first bedding element includes cotton. In another embodiment, the first bedding element comprises at least one of cotton, wool, silk, and a synthetic material. Optionally, the first bedding element is pre-washed, or pre-shrunk, before the portions of the two-part closures 26, 42, 44, 46 are affixed to the first bedding element.

The second bedding element 70 generally comprises an exterior surface 72, an interior surface 74, and a first peripheral edge 76A generally parallel to a second peripheral edge 76B. The second bedding element 70 has a shape generally corresponding to the shape of the first bedding element 30. In one embodiment, a width of the second bedding element 70 is greater than the width of the first bedding element 30. Accordingly, when the second bedding element 70 is interconnected to the first bedding element 30 at least a portion of the first bedding element 30 extends downwardly past the first and second peripheral edges 36A, 36B of the first bedding element 30 as illustrated in FIGS. 1B and 5A. Optionally, the second bedding element 70 is longer than the first bedding element 30.

Slots 56 may be formed proximate to corners of the second bedding element 70 similar to the slots 56 of the first bedding element. Closures may be associated with one or more of the slots 56 to draw the slots 56 at least partially closed.

The second bedding element 70 also includes a second portion 43B of the second closure 42 and a second portion 45B of the third closure 44. The second portions 43B, 45B are positioned on the second bedding element 70 to align with the corresponding first portions 43A, 45A of the first bedding element 30. In this manner, the second bedding element may be selectively interconnected to the first bedding element.

In one embodiment, the second portions 43B, 45B are interconnected to the interior surface portion 74. Optionally, the second portions 43B, 45B may be positioned proximate to the respective first and second peripheral edges 76. In this manner, when the second and third closures 42, 44 are interconnected as generally illustrated in FIG. 5A, the second bedding element 70 drapes from the exterior surface portion 32, around the peripheral edges 36A, 36B and proximate to the interior surface portion 34 of the first bedding element 30. In another embodiment, the second portions 43B, 45B may be spaced from the peripheral edges 76A, 76B as illustrated in FIG. 5B.

Optionally, a second portion 47B of the fourth two-part closure 46 may be interconnected to the second bedding element 70 to align with the first portion 47A. In this manner, a foot portion of the first bedding element 30 may be interconnected to the second bedding element. Accordingly, the first and second portions 47A, 47B of the fourth closure 46 may be separated to provide more room for an occupant of the bed. The first and second bedding elements 30, 70 are generally illustrated as interconnectable using three two-part closures 42, 44, and 46; however, one of skill in the art will appreciate that the any one of the two-part closures 42-46 may independently interconnect the first and second bedding elements. Accordingly, in one embodiment, the first and second bedding elements 30, 70 only include one of the closures 42, 44, 46. In another embodiment, the first and second bedding element 30, 70 include any two of the closures 42, 44, 46. Alternatively, the first and second bedding elements may include all three of the closures 42, 44, 46.

The second bedding element 70 may be any type of a sheet or cover for a bed. The second bedding element 70 may comprise one or more of cotton, silk, nylon, wool, and a synthetic material. In one embodiment, the second bedding element 70 is comprised of a durable material suitable for outdoor use. In one embodiment, at least the exterior surface portion 72 of the second bedding element comprises a water-proof or a water-resistant material.

In one embodiment, the second bedding element 70 is a quilt. In another embodiment, the second bedding element 70 is a duvet-type cover comprising two or more layers that define a cavity or pocket 80. The pocket 80 may be sized to retain an insulating material. Thus, insulation may be removed from, or added to, the pocket 80 to adjust the amount of insulation of the second bedding element 70. In this manner, the second bedding element 70 may be adjusted for year-round used, from a summer-weight duvet to a winter-weight duvet. Optionally, retention elements, such as ties, snaps, or hooks, may be positioned within the pocket 80 for interconnected to a selected insulating material.

Preferably the pocket 80 is closed on at least the first and second peripheral edges 76. Optionally, the pocket 80 is closed proximate to one or more of the foot end 78A and the head end 78B of the second bedding element 70. An aperture 82, illustrated in FIG. 4, for accessing the pocket 80 may optionally be positioned proximate to one or more of the foot 78A and the head 78B of the second bedding element. In one embodiment, the aperture 82 generally comprises a slot in the exterior surface portion 72 of the second bedding element. Alternatively, the aperture 82A is formed in the interior surface portion 74 as illustrated in FIG. 3. Optionally, the aperture 82, 82A may include a closure, such as a zipper, buttons, or snaps. The pocket 80 may be formed on a portion of the width of the second bedding element 70 as illustrated in FIG. 5A. Alternatively, the pocket may generally extend from the first peripheral edge 76A to the second peripheral edge 76B as generally illustrated in FIG. 3.

To replace or clean the bedding system 12, the first and second bedding elements 30, 70 may be individually removed from the retention element 14. Optionally, the first and second bedding elements may be interconnected when the first bedding element 30 is removed from the retention element.

Referring now to FIGS. 6-10, a bedding system 112 of another embodiment of the present invention is generally illustrated. The bedding system 112 is similar to bedding system 12. However, the first and second bedding elements 130, 170 are interconnected to the retention element 114 by buttons. In one embodiment, the buttons are double buttons 162 with a first head and a second head that are interconnected by a shank. Although only five buttons 162 and button holes 160 are illustrated in FIGS. 6-7, this is merely for clarity. Accordingly, a plurality of buttons 162 and button holes 160 may be associated with bedding system 112.

In one embodiment of the present invention, at least the first and second bedding elements 130, 170 include aligned button holes 160A, 160B. The button holes 160A are generally arranged through the first and second bedding elements about parallel to the longitudinal axis 140 of the first bedding element 130. Said another way, the button holes 160A are arranged similar to the positions of the second and third two-part closures 42, 44 of the bedding system 12. Optionally, button holes 160B may be arranged generally perpendicular to the longitudinal axis 140 such that the foot end 178A of the second bedding element 170 may be interconnected to the first bedding element and, optionally, to the retention element.

Optionally, the retention element 114 may also include button holes 160 that align with the button holes 160 of the first bedding element 130 and, optionally, the second bedding element 170. In this manner, one or more double buttons 162 may be used to interconnect the first and second bedding elements to the retention element 114 as illustrated, for example, in FIGS. 9 and 10.

In another embodiment, illustrated in FIG. 11, the buttons 164 are interconnected to the retention element 114. The buttons 164 are positioned on the retention element 114 to be received through the button holes 160 of the first bedding element 130 and, optionally, the second bedding element 170. Preferably, the buttons are interconnected to the retention element 114 such that sufficient space is left between the button 164 and the retention element 114 to receive one or more of the first bedding element and the second bedding element.

Referring now to FIGS. 12-15, yet another embodiment of a bedding system 212 of the present invention is generally illustrated. The bedding system 212 is similar to bedding systems 12, 112 and includes the same or similar features. More specifically, the bedding system 212 includes button holes 260 on the retention element 214 and the first bedding element 230 aligned with buttons 266 affixed to the second bedding element 270. The buttons 266A and button holes 260B may be positioned generally parallel to the longitudinal axis 240 of the first bedding element 230. Accordingly, the buttons 266A and button holes 260A are generally arranged in positions similar to the second and third closures 42, 44 of bedding system 12. Optionally, buttons 266B and buttons holes 260B may be arranged generally perpendicular to longitudinal axis 240 in a manner similar to the fourth fixture 46 of bedding system 12. As illustrated in FIG. 12B, the mattress 2 may optionally include a first closure portion 227 to engage a corresponding second closure portion (not illustrated) of the retention element 214. In this manner, the retention element 214 may be releasably interconnected to the mattress 2.

Referring now to FIGS. 16-20, still another bedding system 312 of an embodiment of the present invention is illustrated. The bedding system 312 includes both a two-part closure 326 to interconnect a retention element 314 to a first bedding element 330 and buttons 366 and button holes 360 to interconnect a second bedding element 370 to the first bedding element 330. Accordingly, the bedding system is similar to bedding systems 12, 112, 212 and includes the same or similar features.

The retention element 314 includes a first portion 327A of the two-part closure 326. A second portion 327B of the two-part closure 326 is affixed to the interior surface 334 of the first bedding element 330 in alignment with the first portion 327A. Accordingly, the first bedding element 330 may be selectively interconnected to the retention element 314 in a manner the same as, or similar to, the retention element 14 and first bedding element 30 of bedding system 12.

The first bedding element 330 also includes button holes 360 to receive buttons 366 affixed to an interior surface 374 of the second bedding element 370. The buttons 366A and button holes 360A are generally parallel to a longitudinal axis 340 of the first bedding element 330. In one embodiment, the buttons 366A and buttons holes 360A are arranged similar to the second and third two-part closures 42, 44 of bedding system 12. Optionally, additional button holes 360B and buttons 366B may be positioned on the first and second bedding elements 330, 370 substantially perpendicular to the longitudinal axis 340 similar to the fourth two-part closure 46 of bedding system 12. In this manner, the foot end 378A of the second bedding system 370 may be selectively interconnected to the first bedding system 330.

Referring now to FIG. 20, in another embodiment, the second bedding element 370A includes buttons holes 360 that are aligned with buttons 368 affixed to the first bedding element 330.
