## Background
CROSS REFERENCE TO RELATED APPLICATION
This application claims the benefit of U.S. Provisional Application Ser. No. 61/205,519, filed Jan. 20, 2009.


FIELD OF THE INVENTION
The present invention relates to bedding.
BACKGROUND OF THE INVENTION
Bedding or bedclothes refers to the customary coverings for a bed, such as sheets and blankets. A sheet is a large piece of cloth used to cover a mattress. This sheet is often referred to as a “bottom sheet,” and it is this sheet that one typically lies on. In many areas of the world, a second flat bed sheet is laid on top of the sheet covering the mattress. This is known as the “top sheet.” One sleeps between the bottom sheet and the top sheet. A comforter, quilt, duvet and other like blanket is then placed on top of the top sheet for warmth. The problem with conventional blankets is that then when two people are sharing the same bed one person may get hot during the night and not require the blanket, while the other person may tend to get cold and wish to use the blanket throughout the night. In the occasions when this occurs, it is often a struggle for the person who is hot to rid or partially rid himself of the blanket without disturbing the entire blanket and possibly disturbing or waking the other person.
SUMMARY OF THE INVENTION
According to the principle of the invention, a bedclothes apparatus includes first and second blankets each sized to cover two occupants of a bed. The first blanket has a first central section and opposed first and second segments formed on either side of the first central section. The second blanket has a second central section, and the second blanket is, according to the principle of the invention, partially severed along the second central section to form a first coverlet having a first marginal edge and an opposed second coverlet having a second marginal edge opposing the first marginal edge. The first coverlet of the second blanket is substantially coextensive with respect to the first segment of the first blanket, and the second coverlet of the second blanket is substantially coextensive with respect to the second segment of the first blanket. A first fastener assembly is formed between the first marginal edge of first coverlet of the second blanket and the first central section of the first blanket to releasably connect the first marginal edge of the first coverlet of the second blanket to the first central section of the first blanket. A second fastener assembly is formed between the second marginal edge of the second coverlet of the second blanket and the first central section of the first blanket to releasably connect the second marginal edge of the second coverlet of the second blanket to the first central section of the first blanket. The first fastener assembly is operable independently of the second fastener assembly to secure the first marginal edge of the first coverlet to and along the first central section of the first blanket to allow the first coverlet to be laid across the first segment of the first blanket, and to release the first marginal edge of the first coverlet from the first central section of the first blanket to allow the first coverlet to be moved away from the first segment of the first blanket and the first central section of the first blanket. The second fastener assembly is operable independently of the first fastener assembly to secure the second marginal edge of the second coverlet to and along the first central section of the first blanket to allow the second coverlet to be laid across the second segment of the first blanket, and to release the second marginal edge of the second coverlet from the first central section of the first blanket to allow the second coverlet to be moved away from the second segment of the first blanket and the first central section of the first blanket. The first fastener assembly is preferably a first slide fastener assembly, and the second fastener assembly is preferably a second slide fastener assembly. In a particular embodiment, the first blanket is a fitted sheet.

Turning now to the drawings, in which like reference characters indicate corresponding elements throughout the several views, attention is first directed to FIGS. 1 and 2 in which there is seen a perspective view of a bedclothes apparatus 30 shown as it would appear assembled and installed on a bed of conventional construction as designated by the reference character 31, which includes the usual mattress 32 positioned atop the usual box spring base 33. Bed 31 may be configured with other conventional structural features such as a bed frame onto which box spring base 33 will typically lie on, a head board, a foot board, and the like. Bed 31 is exemplary of a conventional double bed, queen bed, or king bed being exemplary of the type of bed suitable to comfortably sleep two people. Bedclothes apparatus 30 is an assembly and, according to the principle of the invention, includes opposed, substantially coextensive blankets 40 and 41 each sized to cover two occupants of bed 31. Blanket 40 is a lower or inner blanket of bedclothes apparatus 30, and blanket 41 is an upper or outer blanket of bedclothes apparatus 30. Blanket 41 rests atop blanket 40, which is positioned upon mattress 32 as illustrated in FIGS. 1 and 2 and also FIG. 4, which is a sectional view taken along line 4-4 of FIG. 2.
Referencing FIG. 3, which is an exploded perspective view of bedclothes apparatus 30, blanket 40 is a large, broad piece of cloth, and includes opposed ends 50 and 51, and opposed sides 52 and 53, and a central section 54 between opposed sides 52 and 53 extending from end 50 of blanket 41 to end 51 of blanket 40 and which is parallel with respect to sides 52 and 53 and perpendicular with respect to ends 50 and 51. Central section 54 divides blanket 40 in two opposed halves or segments 55 and 56, which, in the present embodiment, are substantially equal in size and shape. The first half or segment 55 of blanket 40 extends from central section 54 to side 52 of blanket 40 and from and between end 50 of blanket 40 to end 51 of blanket 40 to cover an occupant lying on one side of mattress 32. The second half or segment 56 of blanket 40 extends from central section 54 to side 53 of blanket 40 and from and between end 50 of blanket 40 to end 51 of blanket 40 to cover another occupant lying on the other side of mattress 32.
In this embodiment, blanket 40 is a “fitted” blanket in that its end 51 and sides 52 and 53 are structured to fit about mattress 32 denoted in FIGS. 1-3.

End 50 of blanket 40 is the upper end of blanket 40 designed to be positioned at head 32A of mattress 32 denoted in FIG. 4, and end 51 is designed to be positioned at foot 32B of mattress 32 denoted in FIG. 4, in which the fitted construction of blanket 40 is provided such that corners 61 and 62 fit downwardly about the opposed corners on either side of foot 32B of mattress 32 and end panel 60 extends downwardly and across foot 32B of mattress 32 between corners 61 and 62, side panel 64 extends downwardly and across one side of mattress 32 from corner 61 to end 50 of blanket 40, and side panel 65 extends downwardly and across the opposed side of mattress 32 from corner 62 to end 50 of blanket 40. The fitted construction of blanket 40 prevents blanket 40 from shifting during use of bedclothes apparatus 30 as disclosed herein.
Referencing FIG. 3, blanket 41 is a large, broad piece of cloth, and includes opposed ends 70 and 71, and opposed sides 72 and 73, and a central section 74 between opposed sides 72 and 73 extending from end 70 of blanket 41 to end 71 of blanket 41 and which is parallel with respect to sides 72 and 73 and perpendicular with respect to ends 70 and 71. Central section 74 divides blanket 71 in two opposed coverlets 75 and 76, which are substantially equal in size and shape. The first coverlet 75 of blanket 41 extends from central section 74 to side 72 of blanket 41 and from and between end 70 of blanket 41 to end 71 of blanket 41. The second coverlet 76 of blanket 41 extends from central section 74 to side 73 of blanket 41 and from and between end 70 of blanket 41 to end 71 of blanket 41. Blanket 41 is positioned atop blanket 40 installed on mattress 32 as discussed above, in which coverlet 75 extends over and across segment 55 of blanket 40, coverlet 76 extends over and across segment 56 of blanket 40, end 70 of blanket 41 extends over across blanket 40 adjacent to end 50 of blanket 40, end 71 of blanket 41 extends over and across blanket adjacent to end 51 of blanket 40 and end panel 80 extends over and across end panel 60, side 72 of blanket 41 extends over and across side 52 of blanket 40 and side panel 84 extends over and across side panel 64 of blanket 40, and side 73 of blanket 41 extends over and across side 53 of blanket 40 and side panel 85 extends over and across side panel 65 of blanket 40.
In this embodiment, like blanket 40, blanket 41 is a fitted blanket in that it is structured to fit about blanket 40 fitted about mattress 32 as discussed above. In characterizing the fitted construction of blanket 41, end 71 of blanket is constructed with an end panel 80 extending between opposed corners 81 and 82 formed in end 71 of blanket 41 at sides 72 and 73, respectively, side 72 of blanket 41 is formed with a side panel 84 extending from corner 81 to end 70 of blanket 41, and side 73 of blanket 41 is formed with a side panel 85 extending from corner 82 to end 70 of blanket 41. Side panel 84 and the portion of end panel 80 extending generally from central section 74 to corner 81 can be considered part of or otherwise an extension of coverlet 75 of blanket 41, and side panel 85 and the portion of end panel 80 extending generally from central section 74 to corner 82 can be considered part of or otherwise an extension of coverlet 76 of blanket 41. End 70 of blanket 41 is the upper end of blanket 41 designed to be positioned at head 32A of mattress 32 denoted in FIG. 4, and end 71 of blanket 41 is designed to be positioned at foot 32B of mattress 32 denoted in FIG. 4, in which the fitted construction of blanket 41 is provided such that corners 81 and 82 fit downwardly about the opposed corners of mattress 32 on either side of foot 32B of mattress 32 and end panel 80 extends downwardly and across foot 32B of mattress 32 between corners 81 and 82, side panel 84 extends downwardly and across one side of mattress 32 from corner 81 to end 50 of blanket 41, and side panel 85 extends across the opposed side of mattress 32 from corner 82 to end 50 of blanket 41.
Referencing FIG. 3, blanket 41 is partially severed along central section 74 from end 70 of blanket to a point proximate to and just inboard of end 71 of blanket 41 leaving blanket connected along end panel 80 end 71 of blanket 41 while forming opposed, parallel marginal edges 90 and 91 in blanket 41 and a gap 92 therebetween, and further forming coverlet 75 of blanket 41 extending from marginal edge 90 on one side of gap 92 to side 72 of blanket 41 and between ends 70 and 71 blanket 41, and coverlet 76 of blanket 41 extending from marginal edge 91 on the opposed side of gap 92 to side 73 of blanket 41 and between ends 70 and 71 blanket 41. Segment 55 of blanket 40 is substantially coextensive with respect to segment of blanket 40, coverlet 75 of blanket 41 is substantially coextensive with respect to coverlet 76 of blanket 41, coverlet 75 of blanket 41 is substantially coextensive with respect to segment 55 of blanket 40, and coverlet 76 of blanket 41 is substantially coextensive with respect to segment 56 of blanket 40.
Referencing FIGS. 1-3 and 5, bedclothes apparatus 30 is formed with fastener assemblies 100 and 101. Fastener assembly 100 is formed between marginal edge 90 of coverlet 75 of blanket 41 and central section 54 (referenced in FIGS. 3 and 5) of blanket 40 to releasably connect marginal edge 90 of coverlet 75 of blanket 41 to central section 54 of blanket 40, and fastener assembly 101 is formed between marginal edge 91 of coverlet 76 of blanket 41 and central section 54 (referenced in FIGS. 3 and 5) of blanket 40 to releasably connect marginal edge 91 of coverlet 76 of blanket 41 to central section 54 of blanket 40. Fastener assembly 100 runs along entire length of marginal edge 90 and gap 92 and is operable for securing and releasing coverlet 75 with respect to blanket 40, and fastener assembly 101 likewise runs along the entire length of marginal edge 91 and gap 92 and is operable for securing and releasing coverlet 76 with respect to blanket 40.
Looking to FIG. 5, which is a sectional view taken along line 5-5 of FIG. 1, fastener assemblies 100 and 101 are fitted at gap 92. Fastener assembly 100 is a slide fastener assembly consisting of two strips 110 and 111 of fabric tape that carry complementing rows 112 and 113 of metal or plastic teeth, and a slider 114. Row 112 of teeth may be referred to as an element or engagement element of fastener assembly 100, and row 113 of teeth may be referred to as a complementing element or complementing engagement element of fastener assembly 100. The slider 114, operated by hand, moves along rows 112 and 113 of teeth and meshes together or separates rows 112 and 113 of teeth depending on the direction of movement. According to the invention, slider 114 meshes rows 112 and 113 of teeth together when moved in the direction indicated by the arrowed line A in FIG. 1 toward end 70 of blanket 40, and separates rows 112 and 113 of teeth when moved in the direction indicated by the arrowed line B in FIG. 1 toward end 71 of blanket 41. Fastener assembly 101 is, like fastener assembly 100, a slide fastener assembly consisting of two strips 120 and 121 of fabric tape that carry complementing rows 122 and 123 of metal or plastic teeth, and a slider 124. Row 122 of teeth may be referred to as an element or engagement element of fastener assembly 101, and row 123 of teeth may be referred to as a complementing element or complementing engagement element of fastener assembly 101. The slider 124, operated by hand, moves along rows 122 and 123 of teeth and meshes together or separates rows 122 and 123 of teeth depending on the direction of movement. According to the invention, slider 124 meshes rows 122 and 123 of teeth together when moved in the direction indicated by the arrowed line C in FIG. 1 toward end 70 of blanket 40, and separates rows 122 and 123 of teeth when moved in the direction indicated by the arrowed line D in FIG. 1 toward end 71 of blanket 41.
Because strips 111 and 121 are affixed to each other and also to central section 54 of blanket 40, fastener assembly 100 is operable independently of fastener assembly 101 to secure marginal edge 90 of coverlet 75 with respect to or otherwise to and along central section 54 of blanket 40 to allow coverlet 75 to be laid across segment 55 of blanket 40 as shown in FIGS. 1 and 2, and to release marginal edge 90 of coverlet 75 from central section 54 as shown in FIG. 6 by sliding slider 114 toward end 71 of blanket 41 away from end 70 of blanket 41 to allow coverlet 75 at end 70 to be peeled, folded, or otherwise moved away from segment 55 of blanket 40 and central section 54 of blanket 40 from end 50 of blanket 40, such as when an occupant lying on mattress 32 under segment 55 is too hot and wishes to uncover himself from coverlet 75 from end 50 of blanket 40. Because strips 111 and 121 are affixed to each other and also to central section 54 of blanket 40, fastener assembly 101 is, likewise, operable independently of fastener assembly 100 to secure marginal edge 91 of coverlet 76 with respect to or otherwise to and along central section 54 of blanket 40 to allow coverlet 76 to be laid across segment 56 of blanket 40 as shown in FIGS. 1, 2, and 4, and to release marginal edge 91 of coverlet 76 from central section 54 by sliding slider 124 toward end 71 of blanket 41 away from end 70 of blanket 41 to allow coverlet 76 from end 70 thereof to be peeled, folded, or otherwise moved away from segment 56 of blanket 40 and central section 54 of blanket 40 from end 50 of blanket 40 in exactly the same manner as described and shown in connection with coverlet 76, such as when an occupant lying on mattress 32 under segment 56 is too hot and wishes to uncover himself from coverlet 76. Because strips 111 and 121 are affixed to each other and also to central section 54 of blanket 40, coverlet 75 can be secured and released with respect to central section 54 of blanket independent of and without disturbing coverlet 76, and coverlet 76 can be secured and released with respect to central section of blanket 40 as may be desired with respect to and without disturbing coverlet 75. It is to be understood that with both coverlets 75 and 76 in their secured positions, movement of either coverlet 75 or 76 from its secured position to its released position through the operation of its respective fastener assembly will not disturb the other one of coverlets 75 and 76 from its secured position, in accordance with the principle of the invention, and this is dictated by the structure of the respective fastener assemblies 100 and 101 and their attachment to, and structural association with, blankets 40 and 41.
The fitted configuration of end 71 of blanket 41 helps in the operation of fastener assemblies 100 and 101 by effectively securing blanket 41 in place with respect to mattress 32 and thus stabilizing blanket 41 as sliders 114 and 124 are moved back and forth to secure and release coverlets 75 and 76 during use of bedclothes apparatus 30. Moreover, because blanket 41 is only partially severed as described and is left connected along end panel 80 end 71 of blanket 41, blanket 41 is integrated and bedclothes apparatus 30 is also, therefore, integrated and will not fall apart.
If desired, corners 61 and 62 and end 51 of blanket 40 can be formed with elastic as with well-known elastic fitted sheets to elastically fit end 51 of blanket 40 to mattress 32 to further secure end 51 of cover 40 to mattress 32 to prevent cover 40 from shifting during use of bedclothes apparatus 30. To illustrate this, FIG. 7 is a fragmented perspective view of bedclothes apparatus 30 illustrating end 51 of cover 40 at corner 62 formed with an elastic section 130 as is commonly found among conventional elastic fitted sheets. Although not shown, end 51 of cover 40 at corner 61 can be similarly constructed if so desired, in which case such disclosed details of end 51 of cover 40 at corner 62 apply equally to end 51 of cover 40 at corner 61.
Blanket 40 and blanket 41 are each fitted blankets in the preferred embodiment. In alternate embodiments, blanket 40 can be unfitted and simply constructed as a broad flat blanket, and blanket 41 can be unfitted and simply constructed as a broad, flat blanket. Blanket 40 is used underneath blanket 41. As such, blanket is preferably constructed to be thicker and/or warmer with respect to blanket 40. As such, blanket 40 is preferably a sheet, namely, a top sheet under which a user sleeps, and blanket is preferably 40 formed as a thicker and/or warmer blanket, such as a quilt, duvet, comforter, or the like, that is laid atop blanket 40 for warmth.
Reference is now made to FIG. 8 in which there is seen a perspective view of an alternate embodiment of a bedclothes apparatus 150 constructed and arranged in accordance with the principle of the invention and shown as it would appear assembled and installed on 31 including mattress 32 and box springs 33. In common with bedclothes apparatus 30 bedclothes apparatus 150, as illustrated in FIG. 9, shares blanket 40 having opposed ends 50 and 51, opposed sides 52 and 53, and central section 54 between opposed sides 52 and 53 extending from end 50 of blanket 41 to end 51 of blanket 40, which divides blanket 40 in two opposed substantially equal halves or segments 55 and 56. First half or segment 55 of blanket 40 extends from central section 54 to side 52 of blanket 40 and from and between end 50 of blanket 40 to end 51 of blanket 40 to cover an occupant lying on one side of mattress 32, and second half or segment 56 of blanket 40 extends from central section 54 to side 53 of blanket 40 and from and between end 50 of blanket 40 to end 51 of blanket 40 to cover another occupant lying on the other side of mattress 32. Blanket 40 in bedclothes apparatus 150 is a fitted blanket in that it is structured to fit about mattress 32. In common with blanket 40 in bedclothes apparatus 30, blanket 40 in bedclothes apparatus 150 further shares end panel 60 extending between opposed corners 61 and 62 formed in end 51 of blanket 40 at sides 52 and 53, respectively, side 52 of blanket 40 formed with side panel 64 extending from corner 61 to end 50 of blanket 40, and side 53 of blanket 40 formed with side panel 65 extending from corner 62 to end 50 of blanket 40.

The first coverlet 75 of blanket 41 extends from central section 74 to side 72 of blanket 41 and from and between end 70 of blanket 41 to end 71 of blanket 41. The second coverlet 76 of blanket 41 extends from central section 74 to side 73 of blanket 41 and from and between end 70 of blanket 41 to end 71 of blanket 41. Blanket 41 is positioned atop blanket 40, in which coverlet 75 extends over and across segment 55 of blanket 40, coverlet 76 extends over and across segment 56 of blanket 40, end 70 of blanket 41 extends over across blanket 40 adjacent to end 50 of blanket 40, end 71 of blanket 41 extends over and across blanket adjacent to end 51 of blanket 40 and end panel 80 extends over and across end panel 60, side 72 of blanket 41 extends over and across side 52 of blanket 40 and side panel 84 extends over and across side panel 64 of blanket 40, and side 73 of blanket 41 extends over and across side 53 of blanket 40 and side panel 85 extends over and across side panel 65 of blanket 40.
Like blanket 40, blanket 41 in bedclothes apparatus 140 is, as in bedclothes apparatus 30, a fitted blanket in that it is structured to fit about blanket 40 fitted about mattress 32. In characterizing the fitted construction of blanket 41, end 71 of blanket is constructed with end panel 80 extending between opposed corners 81 and 82 formed in end 71 of blanket 41 at sides 72 and 73, respectively, side 72 of blanket 41 is formed with side panel 84 extending from corner 81 to end 70 of blanket 41, and side 73 of blanket 41 is formed with side panel 85 extending from corner 82 to end 70 of blanket 41. Side panel 84 and the portion of end panel 80 extending generally from central section 74 to corner 81 can be considered part of or otherwise an extension of coverlet 75 of blanket 41, and side panel 85 and the portion of end panel 80 extending generally from central section 74 to corner 82 can be considered part of or otherwise an extension of coverlet 76 of blanket 41. End 70 of blanket 41 is the upper end of blanket 41 designed to be positioned at head 32A of mattress 32 denoted in FIG. 8, and end 71 is designed to be positioned at foot 32B of mattress 32, in which the fitted construction of blanket 41 is provided such that corners 81 and 82 fit downwardly about the opposed corners of mattress 32 on either side of foot 32B of mattress 32 and end panel 80 extends downwardly and across foot 32B of mattress 32 between corners 81 and 82, side panel 84 extends downwardly and across one side of mattress 32 from corner 81 to end 50 of blanket 41, and side panel 85 extends downwardly and across the opposed side of mattress 32 from corner 82 to end 50 of blanket 41.
Blanket 41 of bedclothes apparatus 150 is, as with blanket 41 in bedclothes apparatus 30, severed along central section 74 from end 70 of blanket to a point proximate to and just inboard of end 71 of blanket 41 forming opposed, parallel marginal edges 90 and 91 in blanket 41 and gap 92 therebetween, and further forming coverlet 75 of blanket 41 extending from marginal edge 90 on one side of gap 92 to side 72 of blanket 41 and between ends 70 and 71 blanket 41, and coverlet 76 of blanket 41 extending from marginal edge 91 on the opposed side of gap 92 to side 73 of blanket 41 and between ends 70 and 71 blanket 41. Segment 55 of blanket 40 is substantially coextensive with respect to segment of blanket 40, coverlet 75 of blanket 41 is substantially coextensive with respect to coverlet 76 of blanket 41, coverlet 75 of blanket 41 is substantially coextensive with respect to segment 55 of blanket 40, and coverlet 76 of blanket 41 is substantially coextensive with respect to segment 56 of blanket 40.
Further in common with bedclothes apparatus 30, bedclothes apparatus 150 also shares the slide fastener assemblies forming fastener assemblies 100 and 101 illustrated in FIGS. 8 and 9. Fastener assemblies 100 and 101 are formed at gap 92 between marginal edges 90 and 91. Further, fastener assembly 100 is formed between marginal edge 90 of coverlet 75 of blanket 41 and central section 54 of blanket 40 to releasably connect marginal edge 90 of coverlet 75 of blanket 41 to central section 54 of blanket 40, and fastener assembly 101 is formed between marginal edge 91 of coverlet 76 of blanket 41 and central section 54 of blanket 40 to releasably connect marginal edge 91 of coverlet 76 of blanket 41 to central section 54 of blanket 40. Fastener assembly 100 runs along entire length of marginal edge 90 and gap 92, and fastener assembly 101 likewise runs along the entire length of marginal edge 91 and gap 92.
Having discussed the principal similarities between bedclothes apparatus 30 and bedclothes apparatus 150, the principle differences between bedclothes apparatus 30 and bedclothes apparatus 150 are formed in end panel 80 and fastener assemblies 100 and 101, which, as will be discussed below. In bedclothes apparatus 150, end panel 80 is severed along central section 74 of blanket 41 thereby separating coverlet 75 from coverlet 76 and dividing blanket 41 into two separate parts, namely, coverlet 75 and coverlet 76. Also fastener assembly 100 is fashioned with two sliders including slider 114 and slider 164, and fastener assembly 101 is fashioned with two sliders including slider 124 and slider 174.
The sliders 114 and 164, operated by hand, of fastener assembly 100 each moves along rows 112 and 113 of teeth and mesh together or separates rows 112 and 113 of teeth depending on the direction of movement. In the present embodiment, slider 114 meshes rows 112 and 113 of teeth together when moved in the direction indicated by arrowed line A in FIG. 8 toward end 70 of blanket 40, and separates rows 112 and 113 of teeth when moved in the direction indicated by the arrowed line B in FIG. 8 toward end 71 of blanket 41, whereas slider 164 meshes rows 112 and 113 of teeth together when moved in the direction indicated by arrowed line E in FIG. 8 toward end 71 of blanket 40, and separates rows 112 and 113 of teeth when moved in the direction indicated by the arrowed line F in FIG. 8 toward end 70 of blanket 41. The sliders 124 and 174, operated by hand, of slider assembly 101 each moves along rows 122 and 123 of teeth and meshes together or separates rows 122 and 123 of teeth depending on the direction of movement. According to the invention, slider 124 meshes rows 122 and 123 of teeth together when moved in the direction indicated by the arrowed line C in FIG. 8 toward end 70 of blanket 40, and separates rows 122 and 123 of teeth when moved in the direction indicated by the arrowed line D in FIG. 8 toward end 71 of blanket 41, whereas slider 174 meshes rows 122 and 123 of teeth together when moved in the direction indicated by arrowed line G in FIG. 8 toward end 71 of blanket 40, and separates rows 122 and 123 of teeth when moved in the direction indicated by the arrowed line H in FIG. 8 toward end 70 of blanket 41.
As in bedclothes apparatus 30, fastener assembly 100 is operable independently of fastener assembly 101 to secure marginal edge 90 of coverlet 75 with respect to or otherwise to and along central section 54 of blanket 40 to allow coverlet 75 to be laid across segment 55 of blanket 40 as shown in FIG. 8, and to release marginal edge 90 of coverlet 75 from central section 54 as shown in FIG. 10 by sliding slider 114 toward end 71 of blanket 41 away from end 70 of blanket 41 to allow coverlet 75 from end 70 to be peeled, folded, or otherwise moved away from segment 55 of blanket 40 and central section 54 of blanket 40 from end 50 of blanket 40, such as when an occupant lying on mattress 32 under segment 55 is too hot and wishes to uncover himself from coverlet 75 from end 50 of blanket 41. Likewise, fastener assembly 101 operable independently of fastener assembly 100 to secure marginal edge 91 of coverlet 76 with respect to or otherwise to and along central section 54 of blanket 40 to allow coverlet 76 to be laid across segment 56 of blanket 40 as shown in FIGS. 1, 2, and 4, and to release marginal edge 91 of coverlet 76 from central section 54 by sliding slider 124 toward end 71 of blanket 41 away from end 70 of blanket 41 to allow coverlet 76 from end 70 to be peeled, folded, or otherwise moved away from segment 56 of blanket 40 and central section 54 of blanket 40 at end 50 of blanket 40 in exactly the same manner as described and shown in connection with coverlet 76, such as when an occupant lying on mattress 32 under segment 56 is too hot and wishes to uncover himself from coverlet 76. Coverlet 75 can be secured and released with respect to central section 54 of blanket 40 in this way independent of and without disturbing coverlet 76, and coverlet 76 can be secured and released with respect to central section of blanket 40 in this way as may be desired with respect to and without disturbing coverlet 75.
Unlike bedclothes apparatus 30, in bedclothes apparatus 150 fastener assembly 100 is operable independently of fastener assembly 101 to also release marginal edge 90 of coverlet 75 from central section 54 as shown in FIG. 11 by sliding slider 164 toward end 70 of blanket 41 away from end 71 of blanket 41 to allow coverlet 75 at end 71 to be peeled, folded, or otherwise moved away from segment 55 of blanket 40 and central section 54 of blanket 40 from end 51 of blanket 40, such as when an occupant lying on mattress 32 under segment 55 is too hot and wishes to uncover himself from coverlet 75 from end 50 of blanket 40. Because coverlet 75 is separate from coverlet 76, coverlet 75 can be arranged and moved in this way. Fastener assembly 101 is, likewise, operable independently of fastener assembly 100 to additionally release marginal edge 91 of coverlet 76 from central section 54 by sliding slider 124 toward end 70 of blanket 41 away from end 71 of blanket 41 to allow coverlet 76 from end 71 thereof to be peeled, folded, or otherwise moved away from segment 56 of blanket 40 and central section 54 of blanket 40 from end 51 of blanket 40 in exactly the same manner as described and shown in connection with coverlet 75, such as when an occupant lying on mattress 32 under segment 56 is too hot and wishes to uncover himself from coverlet 76 from end 51 of blanket 40. Because coverlet 76 is separate from coverlet 75, coverlet 76 can be arranged and moved in this way. Also, because strips 111 and 121 are affixed to each other and also to central section 54 of blanket 40 as shown and described in connection with FIG. 5, coverlet 75 of bedclothes apparatus 150 can be secured and released with respect to central section 54 of blanket 40 in the described manner independent of and without disturbing coverlet 76, and coverlet 76 of bedclothes apparatus 150 can be secured and released with respect to central section of blanket 40 in the described manner as may be desired with respect to and without disturbing coverlet 75.
In a further use and configuration of bedclothes apparatus 150, fastener assembly 100 in bedclothes apparatus 150 is useful in completely detaching coverlet 75 from cover 40 as shown in FIG. 12, and fastener assembly 101 in bedclothes apparatus 150 is likewise useful in completely detaching coverlet 76 from cover 40. Coverlet 75 may be detached from cover 40 in two ways, including sliding slider 114 all the way from end 70 of blanket 41 to end 71 of blanket 41 to completely detach row 112 of teeth from row 113 of teeth to thereby completely detach marginal edge 90 of coverlet 75 from central section 54 of blanket 40, or by sliding slider 164 all the way from end 71 of blanket 41 to end 70 of blanket 41 to completely detach row 112 of teeth from row 113 of teeth to thereby completely detach marginal edge 90 of coverlet 75 from central section 54 of blanket 41. Coverlet 75 may be so detached in the instance in which use of coverlet 75 by a user lying under segment 55 of blanket 40 is not desired without disturbing coverlet 76 attached in place and which remains attached in place when coverlet 75 is completely detached. Coverlet 75 may be reattached to central section 54 of blanket 40 simply by re-zipping rows 112 and 113 of teeth back together with either slider 114 or slider 164, which is simply the reverse of the operation used to detach coverlet 75 from blanket 40. Because coverlet 75 is separate from coverlet 76, coverlet 75 can be arranged and moved in this way independent of coverlet 76.
As in bedclothes apparatus 30, in bedclothes apparatus 150 it is to be understood that with both coverlets 75 and 76 in their secured positions, movement of either coverlet 75 or 76 from its secured position to its released position through the operation of its respective fastener assembly will not disturb the other one of coverlets 75 and 76 from its secured position, in accordance with the principle of the invention, and this is dictated by the structure of the respectively fastener assemblies 100 and 101 and their attachment to, and structural association with, blankets 40 and 41.
As with coverlet 75, coverlet 76 may be detached from cover 40 in two ways, including sliding slider 124 all the way from end 70 of blanket 41 to end 71 of blanket 41 to completely detach row 122 of teeth from row 123 of teeth to thereby completely detach marginal edge 91 of coverlet 76 from central section 54 of blanket 40, or by sliding slider 174 all the way from end 71 of blanket 41 to end 70 of blanket 41 to completely detach row 122 of teeth from row 123 of teeth to thereby completely detach marginal edge 91 of coverlet 76 from central section 54 of blanket 41. Coverlet 76 may be so detached in the instance in which use of coverlet 76 by a user lying under segment 56 of blanket 40 is not desired without disturbing coverlet 75 attached in place and which remains attached in place when coverlet 76 is completely detached. Coverlet 76 may be reattached to central section 54 of blanket 40 simply by re-zipping rows 122 and 123 of teeth back together with either slider 124 or slider 174, which is simply the reverse of the operation used to detach coverlet 76 from blanket 40. Because coverlet 76 is separate from coverlet 75, coverlet 76 can be arranged and moved in this way independent of coverlet 75. Because coverlets 75 and 76 can each be detached as described, they can each be easily washed independently of each other, and, moreover, independently of cover 40, such as in a washing machine or by hand if so desired.
It is to be emphasized that the fitted configuration of end 71 of blanket 41 in bedclothes apparatus 150 helps in the operation of fastener assemblies 100 and 101 by effectively securing blanket 41 in place with respect to mattress 32 and thus stabilizing blanket 41 as sliders 114 and 164 in conjunction with coverlet 75 and sliders 124 and 174 in conjunction with coverlet 76 are moved back and forth to secure and release coverlets 75 and 76 during use of bedclothes apparatus 150 as herein specifically described. If desired, corners 61 and 62 and end 51 of blanket 40 can be formed with elastic as with well-known elastic fitted sheets to elastically fit end 51 of blanket 40 to mattress 32 to further secure end 51 of cover 40 to mattress 32 to prevent cover 40 from shifting during use of bedclothes apparatus 30 as shown in FIG. 7 in conjunction with bedclothes apparatus 30.
Blanket 40 and blanket 41 are each fitted blankets in the preferred embodiment. In alternate embodiments, blanket 40 can be unfitted and simply constructed as a broad flat blanket, and blanket 41 can be unfitted and simply constructed as a broad, flat blanket as discussed in connection with bedclothes apparatus 30.
The invention has been described above with reference to preferred embodiments. However, those skilled in the art will recognize that changes and modifications may be made to the embodiments without departing from the nature and scope of the invention. Various changes and modifications to the embodiments herein chosen for purposes of illustration will readily occur to those skilled in the art. To the extent that such modifications and variations do not depart from the spirit of the invention, they are intended to be included within the scope thereof.
