Height adjustable pillow
A height adjustable pillow includes an extendable and resilient pillow body and an air cushion installed in a chamber inside the pillow body. The pillow body is made of soft plastic, rubber or foam products of plastic and rubber. The air cushion can be charged or discharged to adjust the thickness of the pillow, providing comfort with firm support and enhancing sleep quality.
I. Field of the Invention
This invention relates generally to a height adjustable pillow and, more specifically, to a pillow having an extendable and resilient pillow body, inside which installed an air cushion that can be charged or discharged. By adjusting the amount of air filled in the air cushion, the thickness of the pillow can be manipulated.
II. Description of the Prior Art
For a good night's sleep, a soft and fluffy pillow with flexibility is provided with build in head and neck support. A pillow of such construction is typically made of soft plastic, soft rubber, or foam products of plastic and rubber. It is also known to construct a pillow ergonomically designed to have a curved contour, with one higher hump and one lower hump. A pillow of this kind is typically made of special foams to provide pressure relief and is called “memory form”.
Such kind of pillow typically has limited sizes available, which means the shape and thickness can't be freely modified to fulfill different sleep needs. To manufacturers, providing multiple sizes of pillows is not economical since it inevitably increases cost for production and still may not suit all consumers' need. Although some adjustable pillows are available on the market, they are not well-design to meet the needs of consumers.
The present invention improves on the heretofore known pillow by providing an adjustable air cushion inside the pillow so that users can freely modify the thickness to suit their special needs.
SUMMARY OF THE INVENTIONIt is therefore a primary object of the present invention to provide a height adjustable pillow having a pillow body and an air cushion. The pillow body is extendable and resilient, made of soft plastic, rubber, or foam products of plastic and rubber. Inside the pillow body is a chamber for accommodating the air cushion. By charging or discharging air through a valve, the thickness of the pillow can be easily modified.
Another object of the present invention is to provide a height adjustable pillow, of which the air cushion can be freely charged and discharged so that users can modify the thickness of the pillow to create sleep comfort.
BRIEF DESCRIPTION OF THE DRAWINGSThe structure and the technical means adopted by the present invention to achieve the above and other objects can be best understood by referring to the following detailed description of the preferred embodiments and the accompanying drawings, in which:
Referring to
The air cushion 20 is designed to fit the shape and size of the chamber 14 so that the air cushion 20 can be put into the chamber 14 and fill the space in the chamber 14 when the air cushion 20 is fully charged with air. There are two ways of fitting the air cushion 20 in the chamber 14. First, the chamber 14 is thin and flat, with only one lining (not shown in the figures). As the air cushion 20 is discharged, the air cushion 20 is almost flat and will not affect the height of the pillow body 10 or the surface 11 when it is inserted to the chamber 14. Since the space in the chamber 14 is small, and the pillow body 10 is firm and resilient, the pillow body 10 does not depend on the air in the air cushion 20 for support, and so the surface 11 is able to maintain its normal altitude as the air cushion 20 is discharged. Second, the chamber 14 is large enough to leave a relatively empty space, as can be seen in
Refer to
To adjust the altitude of the surface 11 of the pillow 1, users can apply any kind of air pump 2, as shown in
While a preferred embodiment of the invention has been shown and described in detail, it will be readily understood and appreciated that numerous omissions, changes and additions may be made without departing from the spirit and scope of the invention.
Claims
