Abstract
A slipcover with inflatable pillow is provided for furniture comprising a first sheet having an outer layer of fabric attached to an inner layer of thermoplastic, a second, smaller sheet attached to the inner layer of the first sheet so as to form an inflatable pillow, a valve located in at least one of the sheets so as to enable the pillow to be inflated, and a backing layer attached to the first sheet along an edge so as to create a pocket-shaped slipcover with the inflatable pillow in the interior of the slipcover whereby the slipcover can receive a portion of the furniture.
Description




FIELD OF THE INVENTION




The invention relates to an inflatable pillow which is used in conjunction with furniture, and more specifically with outdoor furniture.




BACKGROUND OF THE INVENTION




Inflatable appliques for creating unique articles are known in the art and include a variety of features for converting articles such as towels, shirts, coats, and displays into uniquely configured articles with novel shapes and uses.




There are several U.S. Patents which teach the attachment or addition of a pillow to a towel for use in, for example, sunbathing. U.S. Pat. No. 4,097,944 (Yulish) discloses a stuffed pillow which is permanently formed in the top portion of a towel. U.S. Pat. No. 4,200,942 (Case) and U.S. Pat. No. 3,689,947 (Wolf) teach a towel with a removable pillow which is either inflatable or stuffed. U.S. Pat. No. 2,883,682 (Kwake) teaches an inflatable pillow which is attachable and detachable from a towel using snapping means.




U.S. Pat. No. 3,176,315 (Freund) discloses a beach robe which doubles as a towel with an inflatable pillow. The article taught by Freund fails to teach a means for holding the pillow in place on a piece of furniture when the article is used in its towel configuration.




U.S. Pat No. 4,370,755 (Crumby) discloses a poncho which has a rear panel which can be inflated to create a seat cushion for sitting. Crumby fails to teach an inflatable pillow for the head for use on a piece of furniture which is held in place even when not in use.




I have previously obtained two U.S. Pat. Nos. 5,079,778 & 5,251,337 for inflatable appliques for clothing and towels and a method for producing those appliques. Those patents describe the production of an inflatable applique on material by sealing the pieces of the applique to the material and cutting away the excess. Because many of the techniques and materials described in those patents are also useful in conjunction with the teachings herein disclosed, they are incorporated by reference.




What is desired, therefore, is a pillow which retains its position on a piece of furniture even when not engaged by someone sitting on the furniture. Preferably, the pillow could be used with outdoor chairs or lounges and would be cheaply produced, portable and waterproof, yet comfortable for the user.




SUMMARY OF THE INVENTION




Accordingly, it is an object of the invention to provide a slipcover for furniture that incorporates an inflatable pillow so that the pillow retains its position on a piece of furniture even when not in use.




Still another object of the invention is to provide a slipcover for furniture that contains an inflatable pillow and is relatively easily and inexpensively manufactured.




These and other objects are achieved by a first embodiment in accordance with the invention in which a slipcover is formed from a first sheet having an outer fabric layer that is attached to an inner thermoplastic layer. A second, smaller sheet is attached to the inner thermoplastic layer of the first sheet, and is fitted with a valve so as to form an inflatable pillow. The valve may also be located so that it pierces the first sheet so as to enable inflation outside the slipcover. A backing layer is attached to the first sheet to create a pocket-shaped slipcover inside of which is the inflatable pillow. The backing layer can be an extension of the first sheet which is folded over so that the inner thermoplastic layer overlaps itself, and the inflatable pillow, and is attached at opposing edges to form the pocket shape of the slipcover. Alternatively, a separate backing layer can be attached to cover the inflatable pillow and form the slipcover. The slipcover can then be slipped over a portion of a piece of furniture, such as the back of an arm chair, and thus, hold the inflatable pillow in place whether or not a person occupies the furniture.




Preferably, the outer fabric layer is made from a soft, water-absorbing material like terry cloth affixed to an inner thermoplastic layer made from vinyl. The outer fabric provides comfort to the user, since the user's head will not be in direct physical contact with the vinyl layer of the inflatable pillow, and further enables fast, economic processing.




Also preferably, when polymeric materials are used for the appropriate pieces, the process employed to attach the different components is either radio frequency (RF) sealing or sonic sealing. These methods both allow fast processing times and form strong, air impenetrable seals required for the inflatable pillow.




In a second embodiment, the slipcover with inflatable pillow can be formed by attaching an entirely fabric slipcover to a vinyl material inflatable pillow. The fabric is preferably either a cloth material such as T-shirting or terry cloth or a spunbonded polyolefin such as Tyvek™. This provides additional options for processing, starting materials, and final look of the slipcover with inflatable pillow.




In another aspect of the invention, the slipcover with its inflatable pillow is transformed into a tote bag. This is achieved by folding the slipcover and pillow to bisect the pillow and adding holes positioned so that when the slipcover is folded they align to create a handle at the open end of the slipcover.











These and other objects and advantages of the invention will become apparent from the following detailed description considered with reference to the accompanying drawings.

DETAILED DESCRIPTION OF THE INVENTION




With reference to

FIGS. 1 and 8

, a slipcover


20


is shown with an inflatable pillow


22


in accordance with the invention to hold the inflatable pillow


22


in place on furniture, such as a lounge chair


24


, whether or not the chair is in use. Slipcover


20


is a pocket


23


that enables slipcover


20


to be slipped over the back


25


of chair


24


to hold inflatable pillow


22


in place. Slipcover


20


with its inflatable pillow


22


, typically may be used on outdoor furniture as illustrated in

FIG. 8

; it is understood, however, that a slipcover of this invention can be used on other types of furniture such as on the back of a chair in an airplane, office or car.





FIGS. 2-4

illustrate the construction of a first embodiment of a slipcover


20


in accordance with the invention. A first sheet


26


is formed and includes two layers,


28


and


30


, that are attached together either along edges or otherwise adhered so as to form a laminate. Outer layer


28


is a fabric layer for the comfort of the user. The fabric can be any desired for the intended use of the slipcover


20


, but is preferably a durable, soft, water-absorbing material, such as terry cloth. The fabric can be printed for decoration, for an indication of ownership, or for advertising.




Inner layer


30


is a thermoplastic layer that is suitable for forming one side of inflatable pillow


22


. Although inner layer


30


can be formed from any sufficiently air impermeable material, preferably it is formed from a vinyl sheeting material, expanded vinyl, supported vinyl, neoprene compounds, polypropylene, polyethylene, polyesters, nylons, polyamides, rubber or rubber compounds. The most preferred material is vinyl sheeting as it is simple and cost effective to use in the construction of slipcover


20


.




A second, smaller sheet


32


constitutes the other side of inflatable pillow


22


. Second, smaller sheet


32


is formed from similar material as that used for inner layer


30


. Again the preferred material is vinyl sheeting.




As illustrated in

FIGS. 3 and 4

, second, smaller sheet


32


is attached to inner layer


30


of first sheet


26


to form inflatable pillow


22


. Any means of attaching the sheets is sufficient so long as air is not leaked when pillow


22


is inflated. Preferably second, smaller sheet


32


is sealed or welded to inner layer


30


using radio frequency sealing (RF sealing), sonic sealing, heat sealing, gluing or similar operations. Because RF sealing is fast and cost effective, it is the preferred means of attaching the two sheets when the materials are compatible with the RF sealing operation.




In either first sheet


26


or second, smaller sheet


32


, a valve


34


is located to enable the inflation of inflatable pillow


22


when formed. Although all of the figures illustrate the placement of valve


34


in first sheet


26


, at a position which enables the inflation of inflatable pillow


22


, it is not necessary to locate valve


34


on first sheet


26


. So long as first sheet


26


is of sufficient flexibility that a valve


34


located in second, smaller sheet


32


, inside slipcover


20


, can be reached to inflate pillow


22


, valve


34


can be located in second, smaller sheet


32


to insure maximum comfort when slipcover


20


is in use. Valve


34


preferably is made of a material that is compatible with the materials of sheets


26


and


32


, and is properly placed for comfort. Preferably valve


34


will either be a positive sealing valve or a stem valve as illustrated in my prior patents (U.S. Pat. Nos. 5,079,778 and 5,251,337).




The method for forming slipcover


20


is dependent on the size of first sheet


26


and the placement of second, smaller sheet


32


in relation to first sheet


26


. Typically, inflatable pillow


22


is attached to first sheet


26


off center such that when first sheet


26


is folded along fold


36


, a backing layer


42


is formed from the portion of first sheet


26


opposite inflatable pillow


22


.




When first sheet


26


is folded along fold


36


, inner layer


30


of first sheet


26


overlaps itself to completely encase inflatable pillow


22


, see FIG.


4


.

FIG. 7

illustrates the location of the different components of slipcover


20


with respect to each other after folding first sheet


26


along fold


36


. opposed edges


40


of first sheet


26


are attached so as to form pocket


23


of slipcover


20


with its inflatable pillow


22


which has at least one opening


37


in slipcover


20


to enable the slipping of slipcover


20


over chair


24


to envelope the back


25


of chair


24


, as illustrated in FIG.


1


.




The method used to attach the opposed edges


40


of first sheet


26


should be sufficient to create a slipcover which can withstand the type of use slipcover


20


with its inflatable pillow


22


is intended to endure. The edges can be sewn, RF sealed, sonic sealed, heat sealed, glued, or the like, depending on the materials chosen to form first sheet


26


. Preferably, when inner layer


30


is formed from vinyl, RF sealing or sonic sealing is employed.




First sheet


26


is either folded to exactly bisect its longitudinal axis so that the edges of first sheet


26


at opening


37


meet (

FIG. 1

) or offset so that the edges of first sheet


26


at opening


37


are askew (FIG.


5


).




As depicted in

FIG. 8

, slipcover


20


with its inflatable pillow


22


can now be slipped over a back


25


of a chair


24


and will hold inflatable pillow


22


in place whether or not in use.




An alternative method for forming slipcover


20


described in the first embodiment is illustrated in FIG.


6


. In this method, instead of folding first sheet


26


a backing layer


42


is attached to inner layer


30


of first sheet


26


so as to create pocket


23


of slipcover


20


. As illustrated in

FIG. 6

, first sheet


26


, with attached inflatable pillow


22


, is placed in register with a separate backing layer


42


. Opposed edges


40


are attached to form pocket


23


of slipcover


20


. The same methods taught above to attach opposed edges


40


of first sheet


26


to form slipcover


20


above, can also be employed here for attaching backing layer


42


to first sheet


26


. Backing layer


42


can be formed from any material which is compatible with the desired use of slipcover


20


. For example, backing layer


42


can be formed from any type of fabric, a thermoplastic material like those used to form inner layer


30


, or a laminate thereof. Preferably, both backing layer


42


and inner layer


30


are formed from vinyl sheeting and are RF sealed or sonic sealed at opposing edges


40


to form pocket


23


.




A second embodiment for slipcover


20


is illustrated in FIG.


13


. This second embodiment incorporates the use of an entirely fabric slipcover


20


and an inflatable pillow


22


which is constructed from two separate thermoplastic pieces. First sheet


100


is formed from fabric. Although any fabric can be used depending on the intended use of the slipcover


20


, preferably a soft, water-absorbing material will be employed which could contain polyester, cotton or a blend thereof. Most preferably fabric sheet


100


will be formed from terry cloth made from polyester, cotton or a blend thereof. If, however, a more economical or disposable slipcover


20


is desired, fabric sheet l


00


could be formed from, for example, a spunbonded polyolefin or olefin material such as Tyvek™(a Dupont material).




A valve


102


is placed in a first piece of thermoplastic material


104


. Valve


102


can be any type compatible with the materials, but is preferably either a positive sealing valve or a stem valve. A second piece of thermoplastic material


106


, sized similar to first piece of thermoplastic material


104


, is placed in register with first piece of thermoplastic material


104


. Formation of inflatable pillow


22


can happen using two optional methods. In a first method, illustrated in

FIG. 10

, first piece of thermoplastic material


104


and second piece of thermoplastic material


106


are attached to construct inflatable pillow


22


separate from fabric sheet


100


. After constructing inflatable pillow


22


, it is attached to fabric sheet


100


using RF sealing, sonic sealing, heat sealing, sewing, gluing, adhering, or the like.





FIG. 9

illustrates a second method, in which fabric sheet


100


is placed in register with second piece of thermoplastic material


106


in register with first piece of thermoplastic material


104


, and all three pieces are attached in a single operation. The means used to attach the different pieces can be any which will form an air tight inflatable pillow


22


that is sufficiently attached to fabric sheet


100


for its intended use. The pieces can be attached by RF sealing, sonic sealing, heat sealing, gluing or any combination thereof. If fabric sheet


100


is made from cotton material, the preferred method is RF sealing. If fabric sheet


100


is made from polyester or a blend thereof, preferably either RF sealing or sonic sealing is used.




Processing fabric sheet


100


into slipcover


20


is substantially the same as that described above in the first embodiment for forming a slipcover having a two-layered first sheet


26


. Either fabric sheet


100


can be folded or a backing layer


42


can be employed to create opposing edges


40


which are attached by sewing, RF sealing, sonic sealing, heat sealing, gluing, adhering, or any combination thereof. If RF or sonic sealing are employed, a strip


108


of vinyl sheeting is placed between opposing edges


40


, or around so as to encase opposing edges


40


, of fabric sheet


100


to provide a means for adhering those edges. If fabric sheet


100


is formed from Tyvek™, a strip


108


of adhesive could be employed either between or around the opposing edges to form pocket


23


.




An alternative configuration of inflatable pillow


22


is illustrated in FIG.


13


. In

FIG. 13

, inner layer


30


, or first piece of thermoplastic material


104


, is attached to second, smaller sheet


32


, or second piece of thermoplastic material


106


, at several locations to create a quilted effect of interconnected chambers


110


. Quilted effect of interconnected chambers


110


can be accomplished using any means which creates portions


112


where inner layer


30


is attached to second, smaller sheet


32


while ensuring that all detached portions


114


of inflatable pillow


22


are interconnected so that air entering valve


34


can reach all detached portions


114


. For example, inner layer


30


can be RF, sonic, or heat sealed to second, smaller sheet


32


at all locations which are intended to create attached portions


112


, thus forming interconnected chambers


110


.




Additionally, the inventive slipcover


20


with inflatable pillow


22


is not limited to the use of a single inflatable pillow where both the slip cover and inflatable pillow have the shapes illustrated in the accompanying drawings. Multiple inflatable pillows


22


may be affixed to slipcover


20


for a desired use or design. Likewise, the shape of slip cover


20


and inflatable pillow


22


may be any which is desired for the intended use (e.g. a lumbar support, decorative headrest) but which continues to operate in such a manner that inflatable pillow(s)


22


are held at the desired location on the furniture by slipcover


20


.




An optional addition to slipcover


20


with its inflatable pillow


22


is a handle


120


which converts slipcover


20


with a deflated inflatable pillow


22


into a tote


122


.

FIGS. 15 and 16

illustrate the removal of four oblong holes


124


near opening


37


of slipcover


20


, aligned so that when slipcover


20


with its inflatable pillow


22


is folded along a line


126


which bisects inflatable pillow


22


(FIG.


15


), a single handle


120


is formed, FIG.


14


. Therefore, when folded into tote


122


, articles can be stored in both sections of the interior of slipcover


20


and carried as illustrated in FIG.


16


.




Although the invention has been described with reference to a particular arrangement of parts, features and the like, these are not intended to exhaust all possible arrangements or features, and indeed many other modifications and variations will be ascertainable to those of skill in the art.
