BRIEF SUMMARY OF THE INVENTION
The present invention comprises among other things novel methods and systems for an adjustable cervical contour pillow to support a person in correct posture regardless of whether they are resting in the supine or side lying position. The apparatus has two sides with different sizes and is adjustable to accommodate different sized individuals
This invention relates to a cervical contour pillow which allows people to achieve correct head, neck and upper back posture while sleeping in either the supine or side lying position. Most current cervical contour pillows do not allow correct orthopedic posture for differently sized people. Rather a different sized pillow is required for different sized persons. Most current cervical contour pillows cannot be customized. While some current cervical contour pillows offer correct posture for one position, supine or side lying, they rarely offer it for both, especially being able to fit people of different sizes. Some implementations of the claimed invention have two sides with different sizes and is adjustable to accommodate different sized individuals. The claimed invention solves these shortcomings of the current art of contour cervical contour pillows.
Implementations of a pillow may comprise an adjustable cervical contour pillow comprising a left compartment coupled to a center compartment and a right compartment. The center compartment may be coupled to the left compartment and the right compartment and located between the left and right compartments. Each of the left, the right, and the center compartments may further comprise a mechanical closure configured to receive addition or removal of fill. A first curvature, a web, and a second curvature may be configured such that a height of the first curvature is greater than a height of the web but lower than a height of the second curvature. The center compartment may be further configured such that the height of each of the first curvature, the web and the second curvature of the center compartment are less than the corresponding heights of the analogous portions of the left and right compartments. The compartments may be fluidly independent such that fill material placed in a given compartment cannot travel to the other compartments.
Particular aspects may comprise one or more of the following features. A filled height of the first curvatures of the left and right compartments may be between 6.0 and 6.5 inches. A filled height of the second curvatures of the left and right compartments may be between 6.5 and 7.0 inches. A filled height of the web of the left and right compartments may be between 5.25 and 5.75 inches. A filled height of the first curvature of the center compartment may be between 5.25 inches and 4.75 inches. A filled height of the second curvature of the center compartment may be between 6 inches and 5.5 inches. A filled height of the web of the center compartment may be between 1.25 inches and 0.75 inches. The fill material may be shredded latex. The compartments may be covered with a material that is comprised of a bamboo-cotton blend. The compartments may be covered with a material that is comprised of cotton.
Aspects and applications of the invention presented here are described below in the drawings and detailed description of the invention. Unless specifically noted, it is intended that the words and phrases in the specification and the claims be given their plain, ordinary, and accustomed meaning to those of ordinary skill in the applicable arts. The inventor is fully aware that he can be his own lexicographers if desired. The inventor expressly elects, as his own lexicographer, to use only the plain and ordinary meaning of terms in the specification and claims unless he clearly states otherwise and then further, expressly sets forth the “special” definition of that term and explain how it differs from the plain and ordinary meaning. Absent such clear statements of intent to apply a “special” definition, it is the inventor's intent desire that the simple, plain and ordinary meaning to the terms be applied to the interpretation of the specification and claims.
The inventor is also aware of the normal precepts of English grammar. Thus, if a noun, term, or phrase is intended to be further characterized, specified, or narrowed in some way, then such noun, term, or phrase will expressly include additional adjectives, descriptive terms, or other modifiers in accordance with the normal precepts of English grammar. Absent the use of such adjectives, descriptive terms, or modifiers, it is the intent that such nouns, terms, or phrases be given their plain, and ordinary English meaning to those skilled in the applicable arts as set forth above.
Further, the inventor is fully informed of the standards and application of the special provisions of 35 U.S.C. §112, ¶ 6. Thus, the use of the words “function,” “means” or “step” in the Detailed Description or Description of the Drawings or claims is not intended to somehow indicate a desire to invoke the special provisions of 35 U.S.C. §112, ¶ 6, to define the invention. To the contrary, if the provisions of 35 U.S.C. §112, ¶ 6 are sought to be invoked to define the inventions, the claims will specifically and expressly state the exact phrases “means for” or “step for, and will also recite the word “function” (i.e., will state “means for performing the function of [insert function]”), without also reciting in such phrases any structure, material or act in support of the function. Thus, even when the claims recite a “means for performing the function of . . . ” or “step for performing the function of . . . ,” if the claims also recite any structure, material or acts in support of that means or step, or that perform the recited function, then it is the clear intention of the inventor not to invoke the provisions of 35 U.S.C. §112, ¶ 6. Moreover, even if the provisions of 35 U.S.C. §112, ¶ 6 are invoked to define the claimed inventions, it is intended that the inventions not be limited only to the specific structure, material or acts that are described in the preferred embodiments, but in addition, include any and all structures, materials or acts that perform the claimed function as described in alternative embodiments or forms of the invention, or that are well known present or later-developed, equivalent structures, material or acts for performing the claimed function.
