Embodiments of the present invention relate to a channeled mat. More specifically, embodiments of the present invention relate to a channeled mat that can be utilized as a mat, bedding, pad, seat pad, furniture cushion and other applications, including, but not limited to footwear and insoles.
Mats and bedding are used in numerous applications including user comfort for sitting, standing or lying down. Depending on the environment and material compositions, the mat or bedding may absorb moisture or block air flow, thus causing discomfort to the user. The mat or bedding design or material choice do not handle spills or liquid contact well, usually absorbing or pooling which may cause health issues in addition to discomfort.
In the drawings, which are not necessarily drawn to scale, like numerals describe substantially similar components throughout the several views. Like numerals having different letter suffixes represent different instances of substantially similar components. The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed in the present document.
Embodiments of the invention relate to a channeled mat comprising a mat and one or more channels in the mat. Embodiments also relate to a method of making a channeled mat comprising forming a mat and forming one or more channels in the mat.
The following detailed description includes references to the accompanying drawings, which form a part of the detailed description. The drawings show, by way of illustration, specific embodiments in which the invention may be practiced. These embodiments, which are also referred to herein as “examples,” are described in enough detail to enable those skilled in the art to practice the invention. The embodiments may be combined, other embodiments may be utilized, or structural, and logical changes may be made without departing from the scope of the present invention. The following detailed description is, therefore, not to be taken in a limiting sense, and the scope of the present invention is defined by the appended claims and their equivalents.
In this document, the terms “a” or “an” are used to include one or more than one and the term “or” is used to refer to a nonexclusive “or” unless otherwise indicated. In addition, it is to be understood that the phraseology or terminology employed herein, and not otherwise defined, is for the purpose of description only and not of limitation. Furthermore, all publications, patents, and patent documents referred to in this document are incorporated by reference herein in their entirety, as though individually incorporated by reference. In the event of inconsistent usages between this document and those documents so incorporated by reference, the usage in the incorporated reference should be considered supplementary to that of this document; for irreconcilable inconsistencies, the usage in this document controls.
Embodiments of the invention relate a channeled mat, such as channeled bedding. The channeled mat allows air flow to the portion of the user in contact with the mat and also channels fluid or moisture away from the surface of the mat. The channeled mat may support the head, body and limbs of a user and adjusts for higher and lower weighted areas of the user with the ability to disburse weight through compression and natural movement of the surface layer of the mat. The channeled mat has numerous uses, both for increased comfort and also for alleviating health or medical issues. The channeled mat may be used as bedding, as part of a mattress, wall covering, flooring, seating, exercise mat, portable mat, cushion, furniture, footwear and insoles, floatation device, camping mat, beach chair, etc. Depending on material and design, the channeled mat selectively can be water proof or liquid-absorbable, washable or non-washable, thermally stable or unstable, resistant to shrinkage or shrinkable, resistant to cracks or crackable, bendable or rigid, mold resistant or non-mold resistant, for example. Alternatively, the material choice and design may be customizable depending on the expected use. For increased functionality, the channeled mat may be adjacent to or coupled to an external device, such as a fan, blower or dryer, for example.

The base layer 102 may be formed as one unit with the protrusions 104, such as one-piece construction. One-piece construction may include the entire mat manufactured as one-piece construction, or repeating one-piece units in contact with one another, such as forming multiple levels or layers. The protrusions 104 may be adhered, glued or attached to the base layer 102. Alternatively, the protrusions 104 may be formed by removal of material from a larger base layer 102, such as by laser cutting. The protrusions 104 may be spaced or positioned in such a way as to form one or more channels 106. The protrusions 104 may include a larger surface area in contact with a user and a smaller base in contact with the base layer 102 in order to create larger channels and increased user support.
The shape of the protrusions 104 may be of any shapes and dimensions suitable to support a user and provide one or more channels 106 with which to allow for air or fluid flow, or both. A rectangular-shaped protrusion 202 (
The protrusions 104 may form a channeled layer and may form more than one layer. The channeled mat, protrusions 104, base layer 102, channeled layer or the combination thereof may be manufactured of a combination of materials, such as a composite or laminate. The channeled mat 100, 200 may be manufactured of thermosetting plastics or thermoplastics, for example.
Examples of a thermosetting plastic may include alkyd thermoset, diallyl phthalate (DAP, DAIP) thermoset, epoxy thermoset, melamine (MF, MPF) thermoset, urea (UF) thermoset, phenolic (phenol0-formaldehydes) thermoset, polybuatdiene (PBS, PBAN) thermoset, polyester (unsaturated, UP) thermoset, silicone (both flexible and rigid) thermoset, combinations thereof and laminates thereof.
Examples of a thermoplastic may include acrylonitrile-butadiene-styrene (ABS) amorphous thermoplastic, acetal (polyoxymethylene) (POM) semicrystalline thermoplastic, acrylic (polymethylmethacrylate) (PMMA) amorphous thermoplastic, cellulose acetate (CA) semicrystalline thermoplastic, cellulose acetate butyrate (CAB) semicrystalline thermoplastic, cellulose acetate proprionate (CAP) semicrystalline thermoplastic, ethyl cellulose (EC) semicrystalline thermoplastic, ethylene-vinyl acetate (EVA), polyaryl sulfone (PASU) amorphous thermoplastic, polycarbonate (PC) amorphous thermoplastic, polybutylene terephthalate (PBT) semicrystalline thermoplastic, polyethylene terphthalate (PET) semicrystalline thermoplastic, polyethersulfone (PES) amorphous thermoplastic, polyethylene (PE) semicrystalline thermoplastic, polypropylene (PP) semicrystalline thermoplastic, polyallomer (PAL) semicrystalline thermoplastic, polyimide (PI) amorphous thermoplastic, poly(amide-Imide) (PA-I) amorphous thermoplastic, polymethylpentene (PMP) semicrystalline thermoplastic, polyphenylene oxide (PPO) amorphous thermoplastic, polyphenylene sulfide (PPS) semicrystalline thermoplastic, polystyrene (PS) amorphous thermoplastic, polysulfone (PSU) amorphous thermoplastic, polyvinyl acetal semicrystalline thermoplastic, polyvinyl acetate (PVAC) seimcrystalline thermoplastic, polyvinyl alcohol (PVOH) semicrystalline thermoplastic, polyvinyl carbazole (PVK) semicrystalline thermoplastic, polyvinyl chloride (PVC) semicrystalline thermoplastic, polyvinyl chloride-acetate (PVAC) semicrystalline thermoplastic, polyvinylidene chloride (PVDC) semicrystalline thermoplastic, combinations thereof and laminates thereof.
