BACKGROUND OF THE INVENTION1. Field of the Invention
The present invention relates to methods and apparatus for providing a pillow having adjustable orthopedic and therapeutic utility through a multiplicity of simultaneous adjustment features. The suggested Class for this subject matter is 5/640: “including different adjustable portions which are repositionable relative to each other to change the configuration, dimensions or mode of use.”
2. Description of the Related Art
The following review of related art is intended to provide edifying examples of problems and pitfalls in the design and use of orthopedic pillows having different adjustable portions. The mention of these examples does not constitute an admission that any of the following methods or devices constitute prior art applicable to the present invention. The discussion of the references states what their authors assert, and the applicant reserves the right to challenge the accuracy and pertinency of any of the documents cited herein.
Orthopedics is the branch of medicine that deals with the prevention or correction of injuries or disorders of the skeletal system and associated muscles, joints, and ligaments. Many orthopedic injuries and ailments, particularly in the upper body, and more particularly in the lower back, arise from a person sitting in positions of poor posture or without lumbar support. Physicians recommend orthopedic instruments, such as pillows, for supporting proper posture and the lower back while a patient is seated. However, these devices can be expensive, bulky to carry and store, limited in their applicability for various individuals in various contexts, and they can lose their shape with use.
Orthopedic pillows in the prior art are especially defective in that, after continual use, they become deformed and lose their original shape and resilience. Even from the first use of a pillow, the weight and body shape of a particular patient can cause variable amounts of deformation in that pillow. Such pillows have non-uniform application among the population and they lose utility over time. Often they are not sufficiently adjustable for different postures or locations even though they may be alternatively configured, because the prefabricated solid pieces provide a limited, rather than continuous, serious of adjustable configurations.
U.S. Pat. No. 8,347,435 to Yu issued Jan. 8, 2013 entitled “Pillow with positionable inserts” describes a pillow comprising a casing that surrounds multiple positionable inserts all made from foam or other compressible, deformable solids. In the preferred embodiment of this invention, the multiple positionable inserts must be fastened together by adhesives, clasps, or other means to prevent their sliding out of alignment relative to each other. This device is tedious to assemble and it will deform significantly under pressure and with prolonged use. A similar invention comprising a plurality of foam layers is described in U.S. Pat. No. 8,234,732 to Bacon issued Aug. 7, 2012 entitled, “Orthopedic Pillow.”
The Yu and Bacon patents are the latest in the art of positionable pillows having multiple inner components, and they also represent continued progress towards solving a problem which has long perplexed inventors in this field, which is the problem of having trapped air within a pillow where such trapped air or air pockets interfere with its flexibility. This problem is particularly highlighted in the specification describing a similar pillow in U.S. Pat. No. 7,571,504 to Kuo issued Aug. 11, 2009 entitled “Cushioning device having changeable cushioning members,” the entirety of which is incorporated by reference herein. The Kuo specification asserts that “U.S. Pat. No. 4,628,557 to Murphy, U.S. Pat. No. 4,706,313 to Murphy, U.S. Pat. No. 4,719,656 to Godinet, and U.S. Pat. No. 5,592,706 to Pearce disclose four of the typical cushioning devices each comprising a number of inserts or block bodies or foam bodies assembled together” and which all suffer from a deficiency because “an enclosed or sealed structure” causes a condition wherein “air may not flow or circulate through the inserts or block bodies or foam bodies.” In light of Kuo, it is inferred that the art of adjustable pillows has moved away from the use of sealed air compartments and is focused on pillow designs comprising multiple independent deformable solids that are physically attached to each other or to a solid base via a plurality of fastening devices without having trapped air pockets. The present invention is a complete departure from this mode of adjustable pillow design, and in one sense, the present invention represents a reversal back to embracing trapped air both as a useful feature in itself and as a complement to solid cushion inserts within the same pillow.
The Multifunction Cervical Pillow described in U.S. Pat. No. 7,788,750 to Norstrem issued Sep. 7, 2010 and the Adjustable Contour Pillow U.S. Pat. No. 5,771,514 to Wilhoit issued Jun. 30, 1998 describe a pillow having an outer cushion shell and an internal fluid-filled compartment for use by a person while sleeping or reclining, but not while sitting upright. The outer cushion shell of Norstrem is a single piece comprised of united jacket portions which severely limits its adjustability. The interior fluid-filled compartment is cumbersome and not easily configured for lower back support while in an upright position. The components of Wilhoit are not changeable or swappable. Together, these two inventions and their relatives fail to provide a simple, universal solution to a customizable orthopedic pillow. Related inventions suffering from the same drawbacks are provided, for example, in U.S. Pat. No. 6,047,425 to Khazaal, U.S. Pat. No. 5,533,218 to Fahy, and U.S. Pat. No. 4,534,593 to Ojala.
In light of the above, there exists a need for an orthopedic pillow that has a continuous mode of adjustability based on air pressure or volume and a definite mode of adjustability based upon prefabricated solid inserts, whereby any of the inner air bladders and solid cushion components can be easily swapped with alternative pieces at any time. A further advantage would be gained by providing a customizable outer sheath having at least one, ideally more than one, modes of closure that assists in tightening the entire pillow assembly into a single unit. A still further advantage would be found in such a pillow that were relatively lightweight and exceptionally easy to configure, adjust, and break-down (for storage or transport).
SUMMARY OF THE INVENTIONThe present invention satisfies the above needs. The orthopedic pillow of the present invention features an array of customizable and adjustable features that work in tandem to provide unprecedented adjustability and customizability. The pillow provides a simple, portable, and dynamic tool for supporting and correcting proper physiology of the spine, hips, neck, shoulders, and head, among other parts of the body, not only for a person while sleeping, but also while sitting upright in any environment. The benefits obtained include osteopathological treatment, prophylaxis, and pain relief, as well as enhanced comfort and health even in the absence of any pre-existing ailments. In particular, the pillow provides a convenient means for improving the performance of sofas, wheelchairs, beds and other general seating environments in a customizable, personalized manner.
A first adjustable feature of the pillow of the present invention is an inner inflatable air chamber that can be filled to specified pressures and otherwise adjusted through various means. A first aspect of this adjustable inner air chamber is that it can be swapped in and out of a given pillow, meaning that a particular patient can insert a personalized air chamber custom-fitted to exacting specifications for said particular patient. In preferred embodiments, this inner air chamber also features an air valve or other means for regulating air pressure or volume within the chamber for fine-tuning of the shape and turgidity of said chamber.
A second adjustable feature of said pillow is an adjustable outer cushion layer (cushion shell) that may also be swapped into and out of the pillow such that a given patient may insert a prescribed and customized cushion shell into the pillow surrounding the inner air chamber. This shell may be provided in a single piece or in two or more sectional pieces, such as an upper half and a lower half, or alternatively and preferably phrased as, a “top half” and a “bottom half.” This adjustability feature enables the shell to be fitted to different shapes, resiliency, and sizes on different sides of the pillow. For example, a rounded cushion section may comprise the top half of the shell to contact the lower back of the patient while a square section may comprise the bottom half of the shell to fit snugly against the couch upon which the patient sits. A single-piece cushion shell may be provided as a unitary covering over the inner air chamber, or the cushion shell may comprise several disparate pieces. The “seat” upon which the pillow rests is not limited to a bed or chair, but may be any surface upon which a person desires cushioned support. By properly selecting the various pieces comprising the cushion shell, and by correlating the cushion shell components to the specifications of the inner air chamber, any individual patient may devise the ideal posture control for any seating location or posture condition. And, the same pillow may be adjusted for alternative locations and conditions quickly, easily, and at any time by swapping the inner components.
A third adjustable feature of the pillow of the present invention is inherent in the removable and customizable outer sheath. An optional outermost layer (“sheath”) of the pillow surrounds all of the inner pieces and may help to hold them in place relative to each other, although said inner pieces are preferably formed to snugly interconnect or fit around the inner air chamber. The term “inner pieces” means any of the cushion elements or air chambers. A zipper opens and closes the sheath while an optional second fastening means such as velcro flaps or snaps may provide for alternative and/or additional form control of the pillow unit. For example, the zipper and/or velcro flaps can be a first and a second sheath-closing means, respectively. An alternative nomenclature for these elements is: “means for fastening the outer sheath of the pillow in a closed configuration.” Different and alternative combinations of sheath-closing means may be incorporated into different embodiments of the pillow.
The sheath can be customized with respect to both shape and appearance to accommodate different seating environments. Note that the term “seating” is used broadly to simplify this discussion, and the term “seating” is intended to mean any type of support structure for a person's body. For example, a patient who desires to match the aesthetic appearance of the sheath to a particular sofa may utilize a sheath of a matching color and or fabric to that of the sofa. The same application could be made with a bed, chair, and the like. Alternatively, patients can personalize their orthopedic pillows of the present invention by using colorful custom materials or different fabrics for the sheath, even printing names and logos thereon. Furthermore, custom shapes and fabrics may be used to prepare sheaths suitable for distinctive patients or environments, including for rugged outdoor use, weatherproofing, sanitary use, sterile and hypoallergenic surfaces, and any other application. Similarly to the cushion elements, the sheath may be regarded as having two or more sections or sides, such as an upper section comprising a portion of the sheath that would be proximal to a person during use, and a lower section comprising a portion of the sheath that would be proximal to an underlying support such as a bed or chair.
Finally, the pillow can be broken down for carriage in a briefcase, suitcase, backpack, shrink-wrapped sterile package, and the like simply by deflating the inner air chamber and/or disassembling the inner components. Unlike other adjustable orthopedic pillows, the pillow of the present invention can be completely broken down and re-assembled in mere seconds, and all necessary components can be carried together in a small volume of space.
The forgoing summary has outlined some features consistent with the present invention in order that the following detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated. The present invention is not limited in its application, details, or components merely to those set forth in the following description and illustrations. The present invention resides not merely in any one of the features set forth in this specification, but also in the particular combination of all of the features and improvements claimed. Methods and devices consistent with the present invention are capable of other embodiments. Also, the phraseology and terminology employed herein are for the purpose of description and should not be regarded as limiting unless explicitly stated as such.
Throughout all the Figures, same or corresponding elements are indicated by the same reference numerals.
Situated between the top half 25 and bottom half 26 of cushion element 2 is a pocket for holding an air chamber 12 which may comprise a bladder having bladder walls 9 (upper bladder wall) and 11 (lower bladder wall) and an internal sealed compartment 10 for holding a volume of air or fluid. Said bladder walls 9 and 11 may comprise such materials as, but not limited to, polyurethane film, PVC film, or polyethylene film. The volume of sealed compartment 10 may be controlled by a valve or other means for regulating the ingress and egress of air or fluid (not shown). In summary, in this first embodiment, each of said top half 25 and bottom half 26 of said stuffed shell comprises a sandwich-like structure having two pieces of surface materials (3 and 5 for the top half; 8 and 6 for the bottom half) and two portions of stuffing comprising cushion materials (4 and 7) placed in between said surface materials, respectively.
The inflated air chamber 12 is capable of maintaining proper sitting support without collapsing under body weight and also allows the pillow 100 to constantly conform to a person's body. The cushion element 2 and its various surfaces and stuffing components (i.e., “cushion material”) combine to provide an overall texture, aesthetic appeal, and overall consumer experience comparable to a traditional bed or sofa pillow and can be constructed of materials that are soft, plush, hypo-allergenic, decorated, and otherwise made to resemble the features of traditional pillows for beds, sofas, and the like. For example, outside surface materials 3 and 8 may be selected for their particular texture or thread count, or alternatively for their ability to conform to a desired shape. With regard to functionality, surface materials 5 and 6 are selected so that air chamber 12 can be easily inserted between the different sides of cushion element 2 or any other types of cushion elements, and stably reside therebetween, as appropriate for any particular embodiment of the present invention. An outer sheath may cover one or more of these surfaces in other embodiments, in which cases the end-user experience is further regulated by the texture, shape and construction of the sheath (not shown).
Situated between the top and bottom halves of the cushion shell of pillow 101 is a pocket for holding an air chamber 12 which may comprise a bladder having bladder walls 9 (upper bladder wall) and 11 (lower bladder wall) and an internal sealed compartment 10 for holding a volume of air or fluid. The volume of sealed compartment 10 may controlled by a valve or other means for regulating the ingress and egress of air or fluid (not shown). Surrounding said cushion shell is a sheath 15 fastened in a closed configuration by one or more of a fastening means 17. The sheath may comprise different and distinct compositions on its upper and lower surfaces, 18 and 19 respectively. These alternative compositions may differ in terms of shape, material, and any other properties. In certain embodiments, pillow 101 is identical to pillow 100 but for the addition of the sheath 15.
A method for using the pillow of the present invention is as follows. Before use, a person simply needs to open the cover 15 via unfastening the fastening means 17, and/or select the desired cushion elements and/or assemble them into the desired cushion shell, and/or apply the appropriately selected inner air chamber 12 having the desired turgidity and/or inflate or deflate said air chamber 12 to the most suitable pressure or volume (which may be assisted through the inclusion of a valve 13 in some embodiments). Once the pillow is assembled and the fastening means are fastened shut, the pillow can be placed in the desired location to achieve the desired orthopedic effects or comfort result. Fine adjustments in all of the above features can be made by quickly unfastening the sheath and/or re-arranging the components of the cushion shell, and/or by letting air in or out of the air chamber (in embodiments that have a valve 13). The pillow can be positioned on a bed, chair, or sofa as is done with a conventional pillow. The pillow of the present invention is prevented from collapsing under the person's body weight due to the support provided by the air chamber and yet it will conform smoothly, comfortably, consistently and continuously with the contour of a person's body by virtue of the outer cushion shell in cooperation with said air chamber. Thereby, the person using the pillow of the present invention will receive constant ideal orthopedic support and comfort in any situation.
It should be emphasized that the above described embodiments of the present invention exemplify some, but not all, possible implementations of the present invention and have been set forth in order to provide a clear understanding of its qualities. Those skilled in the art will appreciate that the conception upon which this disclosure is based may readily be utilized as a basis for designing of other structures, methods, and systems for carrying out the several purposes of the present invention. The following claims should be regarded as encompassing equivalent and various constructions insofar as they do not depart from the spirit and scope of the methods and devices consistent with the present invention.
