This disclosure relates generally to pillows with variable cushioning characteristics. More specifically, this disclosure relates to a pillow that include two halves, with each half including a first surface and a second surface opposite from the first surface. The halves may be associated with one another in such a way that an individual may select a softness or firmness of the pillow by selecting which surface(s) is (are) to be oriented adjacent to an outside of the pillow and which surface(s) is (are) to be oriented toward a center, or within an interior, of the pillow. Methods of arranging a pillow with such variable cushioning characteristics are also disclosed.
In one aspect, this disclosure relates to a pillow with variable cushioning characteristics. In various embodiments, such a pillow includes two halves, each of which may be referred to as a “half” or a “pillow half” Each half of the pillow may include a first surface and a second surface, between which an interior of the pillow half is defined.
A cushioning material, such as a fill material, a cushioning element, or the like, may be placed in the interior of each half. In some embodiments, a plurality of cushioning materials may be placed in each half; for example, a first cushioning material may be positioned within the interior of the pillow half, adjacent to the first surface of the pillow half, while a second cushioning material may be positioned within the interior of the pillow half, adjacent to the second surface.
In embodiments where a plurality of cushioning materials are positioned at different discrete locations within in interior of at least one half of the pillow, an intermediate layer may extend across the interior of that half of the pillow. The intermediate layer may separate the interior of its respective pillow half into a first interior portion and a second interior portion, with the first interior portion being located between the intermediate layer and the first surface of the pillow half and the second interior portion being located between the intermediate layer and the second surface of the pillow half. The intermediate layer may include one or more pleats, which may enable it to be moved in a manner that adjusts the volumes of the first interior portion and the second interior portion without substantially changing a collective volume of the interior of the pillow half. Regardless of the configuration of the intermediate layer, the first interior portion of the pillow half may carry the first cushioning material, while the second interior portion of the pillow half may carry the second cushioning material.
In embodiments where an interior of at least one half of the pillow contains at least two cushioning materials at discrete locations, the first cushioning material may comprise a soft material, such as a conventional fill for a pillow. Examples of soft fill materials include, but are not limited to polyester fibers, down, feathers, particles of low density foam rubber, or the like. The first cushioning material may comprise a down-like synthetic material. In a specific embodiment, the first cushioning material may comprise a siliconized polyester fiber. Such materials may impart a first side of the pillow half with a soft and immersive loft.
In embodiments where an interior of at least one half of the pillow contains at least two cushioning materials at discrete locations, the second cushioning material may comprise a relatively firm material, such as an elastomeric material or a fill that comprises an elastomeric material. In some embodiments, the second cushioning material may include fibers formed from an elastomeric gel, such as an unopened blown elastomeric gel fiber. Some other non-limiting examples of such a material include particles of rubber, more specifically, particles of a closed cell foamed rubber, or even more specifically, particles of ethylene vinyl acetate (EVA) foam rubber. Such materials may impart a second side of the pillow half with firmness and stable support.
In other embodiments, each half of the pillow may lack an intermediate layer and include a single type or a single mixture of fill and/or cushioning materials. In such embodiments, each half of the pillow may include the same type or mixture of fill and/or cushioning materials. Alternatively, each half of the pillow may include a different type or mixture of fill and/or cushioning materials than the other half of the pillow.
A first peripheral edge of the first pillow half and a first peripheral edge of the second pillow half may be flexibly coupled to one another along a flexible connector (e.g., a sewn seam, a fabric gusset, etc.,) between the first peripheral edges, while a second peripheral edge of the first pillow half and a second peripheral edge of the second pillow half may be reversibly coupled to one another with a coupler (e.g., complementary zipper halves, buttons, snaps, etc.). One or both of the flexible connector and the coupler may be secured to its respective peripheral edge at a location that is offset from a center of the height of that peripheral edge.
In such embodiments, the pillow has a partially disassembled arrangement when the second peripheral edges of the first pillow half and the second pillow half are uncoupled from one another. In the partially disassembled arrangement, the first pillow half and the second pillow half may be laid side-by-side. An individual may the determine which sides of the pillow halves will be positioned on the outside of the pillow, fold the pillow accordingly along the flexible connector to superimpose the first half and the second half, and couple the second peripheral edges of the first pillow half and the second pillow half to hold the pillow in an assembled arrangement. Positions of the flexible connector and/or elements of the coupler along the heights of their respective peripheral edges of each half of the pillow may enable the pillow to assume a first arrangement in which the pillow is relatively soft and exhibits immersive loft for a supported object, such as a head or another body part of an individual, and a second arrangement in which the pillow is relatively form and provides stable support for the supported object. Thus, the relative orientations of the halves, may at least partially determine whether the pillow is soft or firm, even in embodiments where each half carries a single type or a single mixture of fill and/or cushioning materials. In embodiments where each half of the pillow includes different cushioning materials on opposite sides thereof, the orientation of each side may at least partially determine whether the pillow is soft or firm.
In other embodiments, the first peripheral edges of the first pillow half and the second pillow half may be reversibly coupled to one another and the second peripheral edges of the first pillow half and the second pillow half may be reversibly coupled to one another. Such a pillow may have a completely disassembled arrangement, in which the first pillow half and the second pillow half are completely separate from one another, as well as a partially disassembled arrangement, in which the first pillow half and the second pillow half may be positioned side-by side. In such embodiments, an individual may determine which pillow half is to be positioned on top of the pillow, which cushioning material is to be placed adjacent to an upper surface of the pillow, and which cushioning material is to be placed on a bottom surface the pillow. The individual may then arrange and superimpose the first pillow half and the second pillow half accordingly, couple the first peripheral edges of the first pillow half and the second pillow half, and couple the second peripheral edges of the first pillow half and the second pillow half to place the pillow into an assembled arrangement.
In still other embodiments, the first peripheral edges of the first pillow half and the second pillow half may be flexibly coupled together along a flexible connector (e.g., a sewn seam, a fabric gusset, etc.) and the second peripheral edges of the first pillow half and the second pillow half may be flexibly coupled together along a flexible connector. The first half and the second half of such a pillow are always in an assembled relationship, with the first half and the second half superimposed relative to one another. Such a pillow may be rearranged, however, by pulling the first half and the second half through a center between the first half and the second half, enabling an individual to determine which surfaces of the first pillow half and the second pillow half will define an outside of the pillow, which cushioning material will be oriented toward the outside of the pillow, which surfaces of the first pillow half and the second pillow half will define the center of the pillow, and which cushioning material will be positioned adjacent to the center of the pillow.
Methods for adjusting a pillow to provide a desired cushioning effect are also disclosed, and should be apparent from the foregoing disclosure.
Other aspects of the disclosed subject matter, as well as features and advantages of various aspects of the disclosed subject matter, should be apparent to those of ordinary skill in the art through consideration of the preceding disclosure, the ensuing description, the accompanying drawings, and the appended claims.
