Abstract

Claims (45)

1. A weighted blanket comprising:

a layer of yarn interlooped to create a pattern of regularly spaced openings through the weighted blanket, the weighted blanket having a substantially even weight distribution, wherein the yarn comprises:

an outer tube formed of a fabric that defines a conduit extending longitudinally through an inside of the outer tube; and

a filling arranged within the conduit and comprising a plurality of inner fiber layers, each inner fiber layer extending longitudinally through the conduit and having a fiber layer length that is substantially equal to an outer tube length,

wherein the weighted blanket has a density in a range of between 4.37 pounds per cubic foot and 13.1 pounds per cubic foot, inclusive, and the substantially even weight distribution per square foot in a range of between 0.3 pounds per square foot and 1.5 pounds per square foot, inclusive.

2. The weighted blanket of claim 1 , wherein the weighted blanket comprises a height and wherein the height of the weighted blanket is substantially the same as a diameter of the yarn.

3. The weighted blanket of claim 1 , wherein the plurality of inner fiber lavers comprise at least one of cotton fibers, synthetic fiber, and elastane.

4. The weighted blanket of claim 1 , wherein the filling comprises longitudinally folded sheets of material.

5. The weighted blanket of claim 1 , wherein the filling occupies about 75%-99%, inclusive, of the conduit.

6. The weighted blanket of claim 1 , wherein the filling comprises interlocking inner fiber layers.

7. The weighted blanket of claim 1 , wherein the weighted blanket weighs between 5 pounds and 45 pounds, inclusive.

8. The weighted blanket of claim 7 , wherein the weighted blanket has a length in a range of between 50 inches and 80 inches, inclusive, a width in a range of between 35 inches and 70 inches, inclusive, and a thickness in a range of between 1 inches and 5 inches, inclusive.

9. The weighted blanket of claim 1 , wherein the fabric is a stretch fabric material.

10. The weighted blanket of claim 1 , wherein the yarn comprises a diameter in a range of between one and five inches, inclusive.

11. The weighted blanket of claim 1 , wherein the weighted blanket has the substantially even weight distribution per square foot in a range of between 0.4 pounds per square foot and 1.2 pounds per square foot, inclusive.

12. The weighted blanket of claim 1 , wherein the weighted blanket has the substantially even weight distribution per square foot in a range of between 0.5 pounds per square foot and 1.0 pounds per square foot, inclusive.

13. A weighted blanket comprising:

a layer formed of a continuous strand tubular yarn interlooped to form a pattern of regularly spaced openings to permit air flow through the weighted blanket,

wherein the continuous strand tubular yarn comprises:

an outer tube formed of a fabric and defining a conduit extending longitudinally through an entire length of the outer tube, and

a filling within the conduit, the filling comprising a plurality of fiber layers, each fiber layer extending longitudinally through substantially the entire length of the outer tube,

wherein the weighted blanket has a substantially even weight distribution of between 0.3 pounds per square foot and 1.5 pounds per square foot, inclusive.

14. The weighted blanket of claim 13 , wherein the weighted blanket has the substantially even weight distribution per square foot in a range of between 0.5 pounds per square foot and 1.0 pounds per square foot, inclusive.

15. The weighted blanket of claim 13 , wherein the weighted blanket has the substantially even weight distribution per square foot in a range of between 0.4 pounds per square foot and 1.2 pounds per square foot, inclusive.

16. The weighted blanket of claim 13 , wherein the pattern of regularly spaced openings is configured to permit 18-26% air flow through the weighted blanket.

17. The weighted blanket of claim 13 , wherein the outer tube comprises a diameter in a range of between one and five inches, inclusive.

18. The weighted blanket of claim 17 , wherein the weighted blanket comprises a height and wherein the height of the weighted blanket is substantially the same as the diameter of the tubular yarn.

19. The weighted blanket of claim 13 , wherein the filling comprises elastane.

20. The weighted blanket of claim 13 , wherein the weighted blanket has a length in a range of between 50 inches and 80 inches, inclusive, and a width in a range of between 35 inches and 70 inches, inclusive.

21. The weighted blanket of claim 13 , wherein the weighted blanket has a weight between 5 pounds and 45 pounds, inclusive.

22. The weighted blanket of claim 13 , wherein the weighted blanket has a density in a range of between 4.37 pounds per cubic foot and 13.1 pounds per cubic foot, inclusive.

23. A weighted blanket comprising:

only a single layer formed of a continuous strand yarn interlooped to create a pattern of regularly spaced openings through the weighted blanket, wherein the continuous strand yarn comprises:

an outer tube formed of a fabric that defines a conduit extending longitudinally through the outer tube, and

a filling arranged within the conduit, the filling comprising a plurality of fiber layers, each fiber layer extending longitudinally through substantially an entirety of the conduit,

wherein the weighted blanket further comprises:

a substantially even weight distribution per square foot;

a length in a range of between 50 and 80 inches, inclusive;

a width in a range of between about 35 and 70 inches, inclusive; and

a weight between 5 pounds and 45 pounds, inclusive.

24. The weighted blanket of claim 23 , wherein the filling comprises a single fabric sheet foiled to form the plurality of fiber layers.

25. The weighted blanket of claim 23 , wherein the weighted blanket has the weight distribution per square foot in a range of between 0.5 pounds per square foot and 1.0 pounds per square foot, inclusive.

26. The weighted blanket of claim 23 , wherein the weighted blanket has a density in a range of between 4.37 pounds per cubic foot and 13.1 pounds per cubic foot, inclusive.

27. The weighted blanket of claim 23 , wherein the weighted blanket has the substantially even weight distribution per square foot in a range of between 0.3 pounds per square foot and 1.5 pounds per square foot, inclusive.

28. The weighted blanket of claim 23 , wherein the weighted blanket has the substantially even weight distribution per square foot in a range of between 0.4 pounds per square foot and 1.2 pounds per square foot, inclusive.
