The lengths 76 and 78 can include male and female snap connector portions at their respective distal ends for reconnectably detaching from each-other when force exceeds a threshold.
In some embodiments, the strap 68 can include an elastic material. For example, in some embodiments, the first length 76 can include a length of elastic material (such as a 1-inch width knit elastic material) and the second length 78 can be a length of twill material (such as a 1-inch width twill tape) shorter than the first length 76. The second length 78 can be twill or another substantially non-elastic material so as to provide a relatively stable and strong base for snap-connecting the first length 76. The first length 76 can be elastic so as to allow for stretching and improved fit of the fitted sheet system 18. In some embodiments, the first length 76 can be a 1 inch knit elastic material.
The strap 68 can be configured with the first length 76 being longer than the second length 78 so as to position the connector 70 nearer the side portion 34 (or the side portion 32 in the case of the straps 62 and 66) so as to facilitate ease of access of a user to the connector from the side of the mattress 14 (shown in
The strap 68 can be a breakaway strap and the strap system 60 can be a breakaway strap system so as to reduce the risk of entanglement of children or other users. The connectors 70 can be configured to break (or detach) at a force such that a user can detach the connector to reduce or avoid the risk of entanglement. In some applications, a user could detach the connector 70 to release his or her self from the strap 68. In some applications, a user could detach the connector 70 to release another from the strap 68, such as a parent releasing a child. In some applications, the connector 70 could release automatically when a user becomes entangled in the strap 68 if force exceeds a threshold. After the connector 70 is detached, the connector 70 can be reattached and the strap 68 can be used again as normal.
Length of the straps 62, 64, 66, and 68 of the strap system 60 can also be reduced to further reduce risk of entanglement. In some embodiments, length of the straps 62, 64, 66, and 68 can be as indicated in Table 1. In some embodiments, length of the straps 62, 64, 66, and 68 can be between about 9 inches and about 15 inches when not stretched. In some embodiments in which the straps 62, 64, 66, and 68 include elastic material, length of the straps 62, 64, 66, and 68 can be less than 30 inches when stretched to a maximum length. The location of the straps 62, 64, 66, and 68, with the length of the straps 62, 64, 66, and 68, with the breakaway feature of the straps 62, 64, 66, and 68 can combine to facilitate convenience and safety of the strap system 60.
Accordingly, in some embodiments, not only is the fitted sheet 24 (shown in
In some embodiments, the second sheet 20 includes the button-receiving slits 42 (or other sheet fasteners) for fastening to the sides of the fitted sheet system 18 in addition to the fitted foot end 46. The button-receiving slits 42 can function together in conjunction with the fitted foot end 46 to retain the second sheet 20 in place. The straps 62, 64, 66, and 68 can help retain the fitted sheet system 18 to the mattress 14. The fitted foot end 46 can help retain the fitted foot end 46 of the second sheet 20 to the mattress 14. Although the second sheet 20 could have a tendency to slide down toward the foot of the mattress 14, allowing the second sheet 20 and the fitted foot end 46 to fall off the foot of the mattress 14, the interaction of the button-receiving slits 42 with the button systems 36 of the fitted sheet system 36 can help retain the fitted foot end 46 in-place, and thus retain the second sheet 20 in-place. Accordingly, features of the fitted sheet system 18 and the second sheet system 20 can function as a system to improve a user's experience.
The second sheet 20 can be sized such that, in some embodiments, it is configured to be interconnected with and fit suitably with the fitted sheet system 18 as further explained herein. In some embodiments, suitable sizes for various features of the second sheet 20 are described in TABLE 2, below. Corresponding dimensions are illustrated with respect to reference characters A8-K8 in
In some embodiments, the second sheet 20 can be sized with one, some, or all of the dimensions listed in an embodiment listed in Table 2. In some embodiments, the second sheet 20 can be sized with one, some, or all of the dimensions listed in an embodiment listed in Table 2 and the fitted sheet system 18 can be sized with one, some, or all of the dimensions listed in an embodiment listed in Table 1. In embodiments where the second sheet 20 and the fitted sheet system 18 act together as the sheet system 12, using one or more sizes from Tables 1 and 2 can facilitate the fitted sheet system 18 and the second sheet 20 suitably functioning together as a system for an improved user experience. For example, in some embodiments the sheet system 12 can function such that a user can sleep under the second sheet 20 when the second sheet 20 is buttoned to the fitted sheet system 18. In such embodiments, K8 can be sized to allow a user comfortable space under the second sheet 20 (i.e. space so as to be not too tight and not too loose) when the second sheet 20 is buttoned to the fitted sheet system 18. Because the fitted sheet system 18 and the second sheet 20 function together as a system, the length of the straps 40 as well as the ability of materials to stretch can be factors in the design. For example, in embodiments where the straps 40 and straps 62, 64, 66, and 68 include elastic material, the straps 40 and straps 62, 64, 66, and 68 can stretch when a user is in bed, which can affect suitable dimensions for K8 and for other features of the fitted sheet system 18 and the second sheet 20.
In some embodiments, the sheet system 12 can be configured for use with children's beds. For example, in some embodiments the sheet system 12 can be configured to facilitate children making their beds. In some embodiments, the sheet system 12 can be configured to facilitate children making their beds, with sheets being buttoned in place during the bed making process. In some embodiments, the sheet system 12 can be configured for children sleeping in bed, with the sheets staying in place in a comfortable way during sleep. In some embodiments, the sheet system 12 can be configured both for children making their beds and for children sleeping in their beds. In some embodiments, the sheet system 12 can also be configured for making and sleeping in adult beds.
In some embodiments the strap 40 can have a length configured to allow the button 38 to extend away from the fitted sheet 24 to allow space for movement of the second sheet 20 and/or the blanket 22 when attached to the button system 36. In some embodiments, the strap 40 can have a length between about 1 inch and about 2 inches. In some embodiments, the strap can have a length of about 1.5 inches. The strap 40 can be connected to a portion of the button 38 that is suitably strong to support forces applied to the button 38 by pulling on the second sheet 20 and/or the blanket 22. In some embodiments, the button 38 can be convex on both its top and bottom surfaces such that the button 38 it thickest in its middle section and thinner toward its perimeter. The button can have a diameter of about 1⅜ inch.
A number of embodiments of the invention have been described. Nevertheless, it will be understood that various modifications may be made without departing from the spirit and scope of the invention. For example, some embodiments may include certain features (such one or more as breakaway straps) but not all features disclosed (such as a blanket with button-receiving slits). Additionally, some embodiments may include dimensions of some features in Tables 1, 2, and/or 3 but may modify dimensions of other features or may omit such features entirely. Accordingly, other embodiments are within the scope of the following claims.
