Abstract

A vented blanket is provided that includes opposing first and second panels that define a cavity therebetween. A binding perimetrically bounds and joins the first and second panels. The blanket includes at least one zipper configured to move between a closed position in which air within the cavity is at least partially prevented from escaping through the binding and an open position in which air within the cavity is capable of escaping through the binding.

Description

TECHNICAL FIELD

The present disclosure generally relates to bedding, and more particularly to blankets that include vents to control the amount of heat trapped within the blankets.

BACKGROUND

Sleep is critical for people to feel and perform their best, in every aspect of their lives. Sleep is an essential path to better health and reaching personal goals. Indeed, sleep affects everything from the ability to commit new information to memory to weight gain. It is therefore essential for people to use bedding that is comfortable, in order to achieve restful sleep.

Typically, blankets are configured to provide insulation that keeps a sleeper's body heat between the blanket and a sleep surface to keep the sleeper warm as he or she sleeps. Often times, at least some of the heat between the blanket and the sleep surface will become trapped within the blanket itself, due to the non-porous or low airflow material the blanket is made from. As heat is trapped within the blanket, the blanket may become uncomfortably warm, thus causing the sleeper to remove the blanket. This disclosure describes an improvement over these prior art technologies.

SUMMARY

In one embodiment, in accordance with the principles of the present disclosure, blanket, such as, for example, a vented blanket is provided. The vented blanket includes opposing first and second panels that define a cavity therebetween. A binding perimetrically bounds and joins the first and second panels. The blanket includes at least one zipper configured to move between a closed position in which air and/or thermals within the cavity is prevented from escaping through the binding and an open position in which air and/or thermals within the cavity is capable of escaping through the binding.

In some embodiments, the blanket includes other fastening elements in place of or in addition to the zipper or zippers. The other fastening elements may include, for example, at least one hook and loop fastener (e.g., Velcro), snaps, buttons, at least one zip-locking closure, or a combination thereof.

In some embodiments, the blanket includes a material that at least partially blocks an opening between top and bottom rows of the zipper when the zipper is in the open configuration. The material thus acts as a filter that allows air to move in and out of the cavity, while preventing unwanted debris and/or contaminants from entering the cavity.

In some embodiments, the blanket includes a plurality of zippers that are spaced apart from one another. This allows a sleeper to open or close a selected number of the zippers to vary the amount of heat that is trapped within the blanket, thus allowing for selected amounts of ventilation.

In some embodiments, the blanket includes a quilting pattern in at least one of the panels. In some embodiments, the quilting pattern defines a first pocket and a second pocket that is enclosed within the first pocket. In some embodiments, the zipper defines an opening between top and bottom rows of the zipper when the zipper is in the open configuration, the opening being in communication with the first pocket. This allows heat within the first pocket to move out of the first pocket through the opening and/or ambient air to move into the first pocket through the opening.

For example, the references “upper” and “lower” are relative and used only in the context to the other, and are not necessarily “superior” and “inferior”.

The following discussion includes a description of a blanket, such as for example, a vented blanket in accordance with the principles of the present disclosure. Alternate embodiments are also disclosed. Reference will now be made in detail to the exemplary embodiments of the present disclosure, which are illustrated in the accompanying figures. Turning to FIGS. 1-14, there are illustrated components of a blanket, such as, for example, a vented blanket 30.

Blanket 30 is configured to lie on top of a mattress, with at least one sleeper positioned between blanket 30 and the mattress. In some embodiments, blanket 30 is configured to cover all or a portion of a top surface of the mattress. In some embodiments, blanket 30 is configured to be larger than the top surface of the mattress such that at least a portion of blanket 30 covers all or a portion of a side surface of the mattress. In some embodiments, blanket 30 has substantially the same size and shape as the top surface of the mattress. In some embodiments, the mattress is a standard size mattress, such as, for example, a twin mattress, a full mattress, a queen mattress, a king mattress, or a California king mattress. In some embodiments, the mattress is a crib mattress. In some embodiments, the mattress is a memory foam mattress, an orthopedic mattress (with or without springs), a foam mattress, a mattress that includes gel, a couch mattress, lounge pad or airline or car seat.

Blanket 30 includes various surface fabrics and/or quilting patterns that are configured to allow warm air and/or thermals from a sleeper's body to be trapped between blanket 30 and a mattress and/or within blanket 30, and then dissipated away from the sleeper, thus preventing the warm air from circulating back to the sleeper. At the same time, ambient air from the external environment may pass through and circulate within blanket 30, as discussed herein.

Blanket 30 includes a top layer, such as, for example, a panel 32, as shown in FIG. 1, for example. Panel 32 comprises an end surface 34 and an opposite end surface 36. Surfaces 34, 36 extend between opposite side surfaces 38, 40. Surfaces 34, 36, 38 and 40 are edges of panel 32 that define a perimeter of panel 32. In some embodiments, panel 32 is rounded at all four corners. That is, panel 32 is rounded between surface 34 and 38, between surface 34 and surface 40, between surface 36 and surface 38 and between surface 36 and surface 40. In embodiments wherein panel 32 is rounded at all four corners, panel 32 resembles a rounded rectangle. This configuration allows panel 32 to conform to the shape of a conventional mattress. In some embodiments, surface 34 may be disposed at alternate orientations relative to surface 36, such as, for example, parallel, transverse and/or other angular orientations such as acute or obtuse, tapered, and/or may be offset or staggered. Likewise, in some embodiments, surface 38 may be disposed at alternate orientations relative to surface 40, such as, for example, parallel, transverse and/or other angular orientations such as acute or obtuse, tapered, and/or may be offset or staggered. In some embodiments, panel 32 is variously shaped, such as, for example, oval, oblong, triangular, square, polygonal, irregular, uniform, non-uniform, offset, staggered, undulating, arcuate, variable and/or tapered, depending upon, for example, the shape of the mattress on which blanket 30 is being placed.

As shown in FIG. 2, blanket 30 includes a bottom layer, such as, for example, panel 32A opposite panel 32. Panel 32A comprises an end surface 34A and an opposite end surface 36A. Surface 34A engages surface 34 and surface 36A engages surface 36. Surfaces 34A, 36A extend between opposite side surfaces 38A, 40A. Surface 38A engages surface 38 and surface 40A engages surface 40. Surfaces 34A, 36A, 38A and 40A are edges of panel 32A that define a perimeter of panel 32A. In some embodiments, panel 32A is rounded at all four corners. That is, panel 32A is rounded between surface 34A and 38A, between surface 34A and surface 40A, between surface 36A and surface 38A and between surface 36A and surface 40A. In embodiments wherein panel 32A is rounded at all four corners, panel 32A resembles a rounded rectangle. This configuration allows panel 32A to conform to the shape of a conventional mattress. In some embodiments, surface 34A may be disposed at alternate orientations relative to surface 36A, such as, for example, parallel, transverse and/or other angular orientations such as acute or obtuse, tapered, and/or may be offset or staggered. Likewise, in some embodiments, surface 38A may be disposed at alternate orientations relative to surface 40A, such as, for example, parallel, transverse and/or other angular orientations such as acute or obtuse, tapered, and/or may be offset or staggered. In some embodiments, panel 32A is variously shaped, such as, for example, oval, oblong, triangular, square, polygonal, irregular, uniform, non-uniform, offset, staggered, undulating, arcuate, variable and/or tapered, depending upon, for example, the shape of the mattress that in which blanket 30 is being placed.

Blanket 30 comprises binding 33 that covers panels 32, 32A to join panels 32, 32A together at the perimeters of panels 32, 32A. In some embodiments, binding 33 covers surfaces 34, 34A, 36, 36A, 38, 38A, 40 and 40A. That is, binding 33 is positioned about surfaces 34, 34A, 36, 36A, 38, 38A, 40 and 40A such that an inner surface of binding 33 engages outer surfaces of panels 32, 32A, as shown in FIG. 3. In some embodiments, binding 33 joins panels 32, 32A via stitching 33A that extends through the outer surface of binding 33 a first time, through opposite inner and outer surfaces of panel 32, through opposite inner and outer surfaces of panel 32A and then through the outer surface of binding 33 a second time, as shown in FIG. 3. In some embodiments, binding 33 is rib knit jersey binding, or ripstop nylon binding or other materials or combination thereof. In some embodiments, blanket 30 includes single unit, such as, for example, a single unit that is made up of panel 32 and panel 32A, wherein panels 32, 32A are joined by binding 33 and panels 32, 32A and binding are bound together by stitching 33A. As such, the single unit cannot be taken apart without removing stitching 33A.

In some embodiments, binding 33 comprises a material that is different that the material panel 32 and/or panel 32A is made from. In some embodiments, binding 33 comprises a material that is the same as the material panel 32 and/or panel 32A is made from. In some embodiments, binding 33 is a decorative trim, such as, for example, a ruffle. In some embodiment, stitching 33A is a single needle closure. In some embodiments, stitching 33A is a single needle closure around all edges of panel 32 and/or panel 32A.

As discussed herein, panels 32, 32A have inner surfaces that face one another. The inner surfaces of panels 32, 32A define a cavity 50 of blanket 30 therebetween, as shown in FIG. 3. In some embodiments, cavity 50 is configured for disposal of a fill material 64. In some embodiments, fill material 64 may be any material that provides insulation to keep a sleeper warm or cool. In some embodiments, fill material 64 is configured to trap heat from the sleeper's body between blanket 30 and a sleep surface. In some embodiments, fill material 64 comprises a single layer of material. In some embodiments, fill material 64 comprises multiple layers of material. In some embodiments, fill material 64 comprises a compliant material. In some embodiments, fill material 64 comprises a non-compliant material. In some embodiments, fill material 64 comprises polyester fiber, other man-made fiber or natural fiber, such as but not limited to wool, kapok, latex, foam, memory foam, feathers, gel, memory foam, and/or combinations or blends of the same. In some embodiments, fill material 64 comprises 50% Cluster (e.g., 3D*32 mm w/silicon) and 50% Micro fiber (e.g., 2.5D*32 mm w/silicon. In some embodiments, fill material 64 comprises a single piece of foam. In some embodiments, fill material 64 is a material that makes blanket 30 a cooling blanket. In some embodiments, blanket 30 does not include any fill material between panels 32, 32A. That is, blanket 30 is free of any fill material.

In some embodiments, fill material 64 has an uncompressed volume that is greater than an unexpanded volume of cavity 50. Due to the material(s) from which panels 32, 32A are made and the relative volumes of fill material 64 and cavity 50, cavity 50 may expand as fill material 64 is positioned in cavity 50. As cavity 50 expands, cavity 50 and/or blanket 30 assumes the general shape of fill material 64. In some embodiments, blanket 30 includes at least some air between panels 32, 32A and fill material 64. In some embodiments, panels 32, 32A engage fill material 64 such that there is no air between panels 32, 32A and fill material 64. In some embodiments, fill material 64 is porous such that air in cavity 50 becomes trapped within the pores of fill material 64. In some embodiments, air that is trapped within the pores of fill material 64 can exit blanket 30 through panels 32, 32A and/or an opening created by a zipper, as discussed herein. In some embodiments, fill material 30 is removably positioned within cavity 50. In some embodiments, fill material 30 is secured within cavity 50 by stitching or some other means that fixes fill material 64 to at least one of panels 32, 32A.

When panels 32, 32A are joined by binding 33, a distance between opposite outer surfaces of panels 32, 32A defines a maximum height of blanket 30. In some embodiments, blanket 30 has a maximum height between about 0.10 inches and about 1.0 inch. In some embodiments, blanket 30 has a maximum height between about 0.20 inches and about 0.5 inches. In some embodiments, blanket 30 has a maximum height between about 0.20 inches and about 0.3 inches. In some embodiments, blanket 30 has a maximum height of 0.25 inches. It is envisioned that the maximum height of blanket 30 can be between about 0.05 inches and 3 inches. In some embodiments, blanket 30 has a maximum height that is greater than 3 inches. In one embodiment, the maximum height of blanket 30 is about 1.5 inches.

In some embodiments, panels 32, 32A are each made from a first material. In some embodiments, the first material comprises a porous base material. In some embodiments, the first material comprises a breathable material configured to create enhanced airflow to the sleep surface. In some embodiments, the first material comprises pores that are defined by fibers or strands of the first material, such as, for example, a fabric that makes up the first material. That is, the pores of the first material are the spaces between the fibers or strands of the first material. In some embodiments, the pores have a random configuration (size, shape and/or spacing) that is determined by the arrangement of the fibers or strands of the first material. In some embodiments, the first material has pores that are evenly spaced apart from one another. In some embodiments, the pores are variously shaped, such as, for example, oval, oblong, triangular, square, polygonal, irregular, uniform, non-uniform, offset, staggered, undulating, arcuate, variable and/or tapered. In some embodiments, the first material is a moisture dispersing material. In some embodiments, the first material is a breathable material, such as, for example a breathable fabric. In some embodiments, the first material is non-porous. In some embodiments, the first material has low porosity. In some embodiments, the first material is a heat and moisture wicking material, such as, for example, a porous material and is configured for temperature regulation capability. In some embodiments, the first material comprises acrylic, acetate, cotton, linen, silk, polyester, wool, nylon, rayon, spandex, lycra, hemp, manmade materials, natural materials (e.g., hemp) and blends and/or combinations thereof. Particular materials or blends of materials used are selected according the particular characteristics, price point, durability, and appearance to be achieved. In some embodiments, the first material comprises a fabric or other material that makes blanket 30 wind-proof. In some embodiments, the first material comprises a fabric or other material that makes blanket 30 water-proof.

In some embodiments, panel 32 is made from a material that is different from the material panel 32A is made from. For example, panel 32 or panel 32 may be made from the first material described above and the other one of panel 32 and panel 32A may be made from a material that is different from the first material. Panel 32 may be made from a material that comprises acrylic, acetate, cotton, linen, silk, polyester, wool, nylon, rayon, spandex, lycra, hemp, manmade materials, natural materials (e.g., hemp) and blends and/or combinations thereof, and panel 32A may be made from a material that is different from the material panel 32 is made from. The material panel 32A is made from comprises acrylic, acetate, cotton, linen, silk, polyester, wool, nylon, rayon, spandex, lycra, hemp, manmade materials, natural materials (e.g., hemp) and blends and/or combinations thereof. In one embodiment, panel 32 is made from a breathable fabric and panel 32A is made from a double-layered 3D mesh fabric.

In some embodiments, panels 32, 32A each include a single layer of material, such as, for example, a single layer of fabric. In some embodiments, at least one of panels 32, 32A includes multiple layers of material, such as, for example, fabric. A temperature-regulating material, such as a gel, may be applied interiorly to panel 32 and/or panel 32A to provide cooling and/or warming functionality. The temperature-regulating material may be silicon or polyether gel formed into layers and applied shapes, as well as, formed ceramics, neoprene and other material technology for use to perform heat transfer and temperature regulation function. Depending on the nature and stability of the temperature-regulating material, the temperature-regulating material may be applied internally and/or externally to panel 32 and/or panel 32A.

In some embodiments, panels 32, 32A each include a single layer of fabric. In some embodiments, panels 32, 32A each include multiple layers of fabric. In some embodiments, at least one of panels 32, 32A may include a water resistant or waterproof finish or material. That is, an outer surface of at least one of panels 32, 32A may include a water resistant or waterproof finish or material that prevents water and/or other liquids from entering cavity 50 of blanket 30 and/or penetrating into panel 32 or panel 32A. In some embodiments, the water resistant or waterproof finish or material is gas permeable to allow air to move through blanket 30.

In some embodiments, blanket 30 and/or binding 33 includes one or a plurality of ventilation zippers 58. Ventilation zippers 58 are each movable between a closed configuration (FIG. 5A) and an open configuration (FIG. 5B). When ventilation zippers 58 are in the open configuration, ventilation zippers 58 each define an opening 72 that is in communication with cavity 50. When ventilation zippers 58 are in the open configurations, thermal release and airflow between cavity 50 and the environment surrounding blanket 30 is increased, thus allowing for increased ventilation. When ventilation zippers 58 are in the closed configurations, thermal release and air flow between cavity 50 and the environment surrounding blanket 30 is reduced or prevented, thus allowing for increased insulation.

In some embodiments, ventilation zippers 58 are positioned in different zones, as shown in FIGS. 1 and 2, to allow for different degrees of ventilation or insulation. For example, blanket 30 may include a plurality of ventilation zippers 58 that are spaced apart about blanket 30 thus allowing a sleeper the option to open one or more of the ventilation zippers 58, depending upon the desired amount of ventilation or insulation. As would be recognized by one of ordinary skill in the art, the more ventilation zippers that are opened, the quicker air can move from within blanket 30 (e.g., cavity 50) to an area outside of blanket 30. Therefore, a sleeper can control the amount of ventilation or insulation provided by blanket 30 by selectively opening a desired number of ventilation zippers 58. For example, the sleeper can open additional ventilation zippers 58 when increased ventilation is required by opening ventilation zippers 58 to allow heat within cavity 50 to escape blanket 30. In embodiments, ventilation zippers 58, rather than stitching 33A join panel 32 to panel 32A at portions of blanket 30 that include ventilation zippers 58, as shown in FIG. 4. Panel 32 is joined with panel 32A by stitching 33A as described above in other portions of blanket 30 that do not include ventilation zippers 58, as also shown in FIG. 4.

In some embodiments, ventilation zippers 58 are positioned in different zones, as shown in FIGS. 1 and 2, to allow multiple sleepers to each control the degree of ventilation or insulation on one side of blanket 30. For example, ventilation zippers 58 on one side of blanket 30, such as, for example, a side of blanket 30 adjacent surface 38 can control the degree of ventilation or insulation on side of blanket 30 adjacent surface 38 and ventilation zippers 58 on one side of blanket 30, such as, for example, a side of blanket 30 adjacent surface 40 can control the degree of ventilation or insulation on side of blanket 30 adjacent surface 40. This configuration allows each sleeper to control individual thermal release or retention on their side of blanket 30. For example, the sleeper on the right side of blanket 30 (e.g., the side of blanket 30 adjacent surface 40) can control their core temperature, and the person on the left side of blanket 30 (e.g., the side of blanket 30 adjacent surface 38) can also individually control their core temperature by each opening or closing their respective ventilation zipper(s) 58, as they prefer.

In some embodiments, each sleeper may have only a single ventilation zipper 58 for their core (chest area). For example, blanket 30 may include two ventilation zippers 58, wherein one of the ventilation zippers 58 is positioned along surface 38, between surfaces 32, 34 and the other ventilation zipper 58 is positioned along surface 40, between surfaces 32, 34.

In some embodiments, each sleeper may have multiple ventilation zippers 58 for zones for custom temperature-regulation from head-to-toe, such that they have shoulder area and/or lower extremity (foot) zippers, with or without having the chest area zipper, or other body areas. For example, ventilation zippers 58 for one of the sleepers may be positioned along surface 38, wherein one or more ventilation zippers 58 are positioned adjacent to one of sleeper's shoulder area and one or more ventilation zippers are positioned adjacent to the sleeper's lower extremity; ventilation zippers 58 for the other sleeper may be positioned along surface 40, wherein one or more ventilation zippers 58 are positioned adjacent to the other sleeper's shoulder area and one or more ventilation zippers are positioned adjacent to the other sleeper's lower extremity.

As discussed above, binding 33 is positioned about surfaces 34, 34A, 36, 36A, 38, 38A, 40 and 40A such that an inner surface of binding 33 engages outer surfaces of panels 32, 32A, as shown in FIG. 3. Binding 33 includes a fold 66 between one of surfaces 34, 36, 38, and 40 and another one of surfaces 34A, 36A, 38A and 40A, as also shown in FIG. 3. In some embodiments, ventilation zippers 58 are positioned at fold 66 and each include a first portion, such as, for example, a first set of teeth 58a coupled to an upper portion 68 of binding 33 and a second portion, such as, for example, a second set of teeth 58b coupled to a lower portion 70 of binding 33, as shown in FIGS. 5A and 5B.

In some embodiments, blanket 30 includes a single ventilation zipper 58. In some embodiments, the single ventilation zipper 58 is positioned along one or more of surfaces 34, 34A, 36, 36A, 38, 38A, 40 and 40A. In some embodiments, the single ventilation zipper 58 extends around the entire perimeter of blanket 30. In some embodiments, the single ventilation zipper 58 extends around a majority of the perimeter of blanket 30.

FIG. 5A shows one of ventilation zippers 58 in the closed configuration and FIG. 5B shows one of ventilation zippers 58 in the open configuration. As shown in FIG. 5B, upper and lower portions 68, 70 of binding 33 are separated from one another by opening 72 when ventilation zippers 58 are in the open configuration. Upper and lower portions 68, 70 of binding 33 engage one another to close opening 72 when ventilation zippers 58 are in the closed configuration, as shown in FIG. 5A. Opening 72 is in communication with cavity 50 such that air within cavity 50 of blanket 30 can move in and out of cavity 50 through opening 72. In some embodiments, heated air within cavity 50 moves out of cavity 50 through opening 72 and cooler, ambient air moves into cavity 50 through opening 72.

Ventilation zippers 58 each include a slider 74 and a pull tab 76 that is attached to slider 74, as shown in FIGS. 5A and 5B. Slider 74 is moved relative to teeth 58a, 58b in a first direction, such as, for example, direction A shown in FIG. 5A to move zipper 58 from the closed configuration to the open configuration. As slider 74 moves in the first direction, slider 74 pulls teeth 58a away from teeth 58b. Slider 74 may then be moved in a second direction, such as, for example, direction B shown in FIG. 5A to move zipper 58 from the open configuration to the closed configuration. As slider 74 moves in the second direction, slider 74 brings teeth 58a, 58b together such that teeth 58a interlock with teeth 58b.

In some embodiments, blanket 30 includes a filter, such as, for example, a material 78 that at least partially blocks opening 72 when zipper 58 is in the open configuration. In some embodiments, material 78 is porous to allow air to move in and out of cavity 50 of blanket 30 through material 78 and opening 72. In some embodiments, material 78 comprises fabric. In some embodiments, the fabric is a breathable fabric. In some embodiments, material 78 comprises the same material as at least one of panels 32, 32A. In some embodiments, material 78 comprises a material that is different than the material that at least one of panels 32, 32A is made from. In some embodiments, material 78 comprises one or more of the materials discussed herein. In some embodiments, material 78 comprises a top end 78a that is coupled to upper portion 68 of binding 33 and a bottom end 78b that is coupled to lower portion 70 of binding 33. In some embodiments, top end 78a is coupled to panel 32 and bottom end 78b is coupled to panel 32A. Material 78 is configured to prevent dust, debris or other contaminants from entering cavity 50 of blanket 30 when zipper 58 is in the open configuration, while still allowing air to move in and out of cavity 50 of blanket 30 through material 78 and opening 72. In some embodiments, material 78 collapses within cavity 50 such that material 78 is positioned entirely within cavity 50 when zipper 58 is in the closed configuration.

In some embodiments, shown in FIGS. 6 and 7, blanket 30 includes stitching 35 that extends through inner and outer surfaces of panel 32 and panel 32A. Stitching 35 defines a quilting pattern forms one or a plurality of pockets 37 between panel 32 and panel 32A. In some embodiments, pockets 37 are defined by inner surfaces of panels 32, 32A that face one another and stitching 35. In some embodiments, pockets 37 are defined by the inner surfaces of panels 32, 32A that face one another, stitching 33A and stitching 35. In some embodiments, at least one of pockets 37 is in communication with opening 72 such that air within pockets 37 can move out of pockets 37 through opening 72 or ambient air can move through opening 72 and into pockets 37 when zipper 58 is in open configuration. In some embodiments, the quilting pattern defined by stitching 35 is designed to circulate air through blanket 30, as well as within blanket 30, across the sleeper's body.

Pockets 37 are configured to trap heat from a user's body that moves into blanket 30 through panel 32 and/or panel 32A to prevent the heat from returning to the sleep surface, so as not to increase the temperature of the sleep surface, as discussed herein. As would be recognized by one of ordinary skill in the art, a single pocket or a series of pockets that are positioned side-by-side across a width of blanket 30 or top-to-bottom along a length of blanket 30 may not be sufficient to properly trap heat within blanket 30. As such, blanket 30 includes a plurality of pockets 37, wherein some of pockets 37 are positioned within other pockets 37. It has been found that this configuration of pockets 37 properly retains heat from a sleeper's body within pockets 37 in a manner that prevents the heat within pockets 37 from returning to the sleep surface. In some embodiments, heated air within pockets 37 will move through panel 32 and/or panel 32A and into an environment, such as, for example, a room, wherein the ambient temperature in the environment is less than the temperature of the air within pockets 37. This will lower the temperature of the air within pockets 37, thus preventing blanket 30 from feeling too warm or hot to the sleeper.

In some embodiments, blanket 30 may include one or more channels, such as, for example, open air channels that allow for cooling and/or heating. In some embodiments, at least one of the channels is defined by one or more of pockets 37. That is, the channels are the space within pockets 37. In some embodiments, the channels are configured to bring cool air from the room environment across the lower surface of blanket 30 (e.g., the outer surface of panel 32A) and through the material that defines the channels and pockets 37 to provide additional ventilation for temperature-regulation to the sleeper, which may result in a cooler feeling, or alternately, when desired, a warmer feeling. In some embodiments, the cooler feeling and the warmer feeling is due to the air temperature of the room environment in which blanket 30 is positioned. In some embodiments, the warmer feeling is due to a heating element that is embedded in blanket 30. In some embodiments, one or more heating elements are positioned within one or more of the channels. In some embodiments, the cooler feeling and/or the warmer feeling is created by temperature-regulating materials. In some embodiments, the temperature-regulating materials are embedded in blanket 30. In some embodiments, the temperature-regulating material is embedded within one or more of the channels.

In some embodiments, the channels can have various shape configurations, such as, for example, circular, oval, oblong, square, rectangular, polygonal, irregular, uniform, non-uniform, variable and/or tapered. In some embodiments, one or more of the channels has an end adjacent to an edge of at least one of panels 32, 32A such that air from the room environment can enter the channels and move laterally through the channels to provide ventilation. In some embodiments, blanket 30 is configured such that one or more of the channels extends from one edge of at least one of panels 32, 32A (e.g., surface 38 or surface 34) to another edge of at least one of panels 32, 32A, such as, for example, an opposite edge of at least one of panels 32, 32A (e.g., surface 40 or surface 36). This configuration allows air from the room environment to move continuously from one side or end of blanket 30 to an opposite side or end of blanket 30 such that the air can exit blanket 30 on the opposite side or end from where the air entered using a single channel. The air will provide a warm or cool feel to a sleeper that is resting under blanket 30 as the air moves through the channel.

In some embodiments, at least one of the channels includes a top surface that engages the inner surface of panel 32, a bottom surface that engages the inner surface of panel 32A and spaced apart side surfaces that that each extend from the top surface to the bottom surface such that the channels resemble a hollow tube. The channels include openings at opposite ends of the channel. This configuration allows ambient air to flow continuously through blanket 30.

In some embodiments, the channels are spaced apart from one another such that air in one channel cannot enter another channel. In some embodiments, at least one of the channels is in communication with at least one of the other channels such that air in one of the channels can enter another one of the channels.

In some embodiments, stitching 35 reduces the profile of stitched portions of panels 32, 32A to create different elevations of the fabric structure, so that there are highs and lows of profile that increase air circulation in around and through outer surfaces of panels 32, 32A, and between the outer surfaces of panel 32 and panel 32A.

Zippers 58 are positioned about a perimeter of blanket 30, as shown in FIGS. 1 and 2. In some embodiments, shown in FIGS. 8-14, blanket 30 includes at least one central zipper 80 in place of or in addition to zippers 58. In some embodiments, shown in FIGS. 8-10, zippers 80 are each positioned solely in panel 32. In some embodiments, shown in FIGS. 11-14, zippers 80 are each positioned in panels 32, 32A. In some embodiments, blanket 30 includes other fastening elements in place of or in addition to the zipper or zippers 80. The other fastening elements may include, for example, at least one hook and loop fastener (e.g., Velcro), snaps, buttons, at least one zip-locking closure, or a combination thereof. In one embodiment, blanket 30 includes a single zipper 80 positioned between surfaces 38, 40. In one embodiment, the single zipper 80 is positioned equidistantly between surfaces 38, 40.

In some embodiments, material 86 collapses within cavity 50 such that material 86 is positioned entirely within cavity 50 when zipper 80 is in the closed configuration.

In some embodiments, shown in FIGS. 11-14, zippers 80 each include a first set of teeth 80c coupled to each of panels 32, 32A and a second set of teeth 80d coupled to each of panels 32A. In some embodiments, teeth 80c, 80d join panel 32 with panel 32A. Zippers 80 are each movable between a closed configuration (FIGS. 11 and 12) and an open configuration (FIGS. 13 and 14). As shown in FIGS. 13 and 14, teeth 80c, 80d are separated from one another by an aperture 88 when zippers 80 are in the open configuration. In some embodiments, apertures 88 are spaced apart from cavity 50 by zippers 80. Teeth 80a, 80b engage one another to close aperture 88 when zippers 80 are in the closed configuration, as shown in FIGS. 11 and 12. Aperture 88 extends through inner and outer surfaces of panel 32 and inner and outer surfaces of panel 32 such that ambient air can move directly through aperture 88 to contact the sleeper when the sleeper is positioned between blanket 30 and a mattress.

Zippers 80 each include a slider that is the same as or similar to slider 74 and pull tab 76. The slider and pull tab 84 moved relative to teeth 80c, 80d in a first direction to move zipper 80 from the closed configuration to the open configuration. As the slider and pull tab 84 move in the first direction, the slider pulls teeth 80c away from teeth 80d. The slider and pull tab 84 may then be moved in a second direction to move zipper 80 from the open configuration to the closed configuration. As the slider and pull tab 84 move in the second direction, the slider brings teeth 80c, 80d together such that teeth 80c interlock with teeth 80d.

In some embodiments, blanket 30 may include a heating and/or cooling element within cavity 50 and/or within at least one of pockets 37a, 37b, 37c, 37d, 37e, 37f, 38g to allow a sleeper to match the temperature of cavity 50 and/or at least one of pockets 37a, 37b, 37c, 37d, 37e, 37f, 38g according to his or her sleep preference.
