BACKGROUND OF THE INVENTION
2. Prior Art
Generally, prior patents and patent applications disclose leg and/or foot pillows which do not serve the same purpose nor give the same benefits as the present invention, and whose structure or configuration and theory of operation as to place, manner, time, duration of use, and user and user's condition, are in direct contrast with those of the present invention in many ways. Examples of prior patents include the following:
U.S. Pat. No. 3,901,228 discloses a therapeutic foot rest for not for normal persons but patients, and comprises a resilient foam boot having a base and upstanding side walls defining a cavity for receiving a patient's foot and holding the foot in an upright position, the end wall opposing the sole of the patient's foot being resiliently compressable against the footboard of the patient's bed to enable therapeutic exercise.
U.S. Pat. No. 3,931,654 discloses a Leg Positioner as a device for positioning and supporting the lower leg ankle and foot not of a normal person lying supinely on his or her back, but a patient as a unit while lying on his or her side during periods of extended rest, structured so as to enable the patient to lie on his side with the uppermost leg portion being positioned perpendicularly to the lower leg position which is positioned perpendicularly to the foot.
U.S. Pat. No. 3,946,451 discloses a Limb Support, made from a block of polyurethane foam having resilient characteristics, which has a continuous open topped arcuate groove extending longitudinally along the length of the block for receiving, cradling and resiliently gripping the limb not of a normal person, but of a hospitalized patient to avoid rotation of the limb supported thereby to prevent the formation of decubitus ulcers or bedsores on the heel.
U.S. Pat. No. 5,134,739 discloses a pillow for persons required to remain in supine position for an extended period of time.
U.S. Pat. No. 5,216,771 discloses a pillow with an hourglass shape for placing between the legs of an individual when lying on his or her side to provide for proper adjustment of the spine, hips and knees.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT AND OPERATION
Before the embodiments of this invention are explained in detail, it is to be understood that the invention is not limited in its application to the details of construction and arrangements of components set forth in the following description or illustrated in the drawings. The invention is capable of other embodiments and of being carried out in other ways. Also, it is to be understood that the phraseology and terminology used herein is for the purpose of description and illustration and should not be regarded as limiting.
Referring now to the drawings, it is seen that the FIG. 1 depicts a sideview or right side or eastern side of an embodiment of the invention (with two covers: first, its inner lining or cover made of cloth or other lining material sewn, zippered, or otherwise done or made to cover the body of the invention, and second, a pillowcase or other material to cover the lining and the body of the invention) in its intended position.

FIG. 3C depicts the pillow when flipped over to show that the bottom surface of the pillow can be used on which to rest the calf (at the back end 24) and heel (at the front end) of both legs of the user.
DESCRIPTION—ADDITIONAL OR ALTERNATIVE EMBODIMENTS AND OPERATION
FIGS. 7B, 8A (broken lines depicting the route of the zipper or other closure on only one side of the pillow), and 8B are additional embodiments that the present invention is capable of. The user's lower legs and feet are placed in the manner similar to the way depicted in FIG. 2. FIGS. 9A, 9B and 9C depict alternative non-circular embodiments of the front end 20 the invention.
Aside from a flat top surface 10, flat portion of the bottom surface 14, flat back end 24 and flat left and right sides of the invention, an alternative embodiment may have a corrugated or other non-flat surface for such surfaces and sides.
CONCLUSION, RAMIFICATIONS AND SCOPE
The device constructed in accordance with the present invention may be used advantageously to provide therapy, relaxation and relief from physical and mental stress, strain, tension, fatigue from standing, working, shopping or otherwise being active for long hours, by using it while the user is conveniently at home, or in a sofa or other place in the office or any other place where the user can place his or her lower legs and feet on the pillow and lie down supinely. The benefit comes from the user placing both lower legs and feet on the top surface of the invention and resting his or her body on the surface of a bed, sofa, carpeted floor or other flat or similar surface. After a few minutes, the work is done! This simple, self-help relief thus would improve blood circulation, reduce physical and mental stress from tension, strain, travel, and long hours of standing at work, home or walking, shopping, or other physical activity involving the legs, and also helps prevent varicose veins. This invention is for young and old adults and not necessarily for patients only. The unique form and structure of the invention contributes to the benefits accruing from its use. Made of foam or other material of compact or solid mass with resiliency to permit its insertion into an inner line or cover and an outer covering like a pillowcase or other cover, it is shaped by a factory computerized cutter.
The use of the invention is simple. It is light and portable and thus can be used anywhere where the user can lie down supinely. The user needs only to place both lower legs from the calf up to the heel on the top surface of the invention and lie down on his or her back for short durations of time like twenty minutes rather than extended periods. Although the curving, or circular front end of the invention extends to the bottom surface, like the letter “P” in prone position, this invention can be flipped over and used in the same manner for the aforementioned benefits.
While the pillow may be made from other resilient material or made of inflatable material, the best mode of the invention is to form the invention of firm but resilient foam, because the foam retains better shape, which allows proper retention of the pillow and its use for a long period of time.
The invention admits of other forms, configurations, and variations shown in the drawings. Capable of multipurpose use, it can be used in other ways like a head and upper back pillow while watching TV or cable video or resting or otherwise resting, or in hospitals or other healthcare facilities for patients' relief and relaxation during the healing process.
Although the description above contains many specificities, these should not be construed as limiting the scope of the invention, but as merely providing illustrations of some of the presently preferred embodiments of this invention. For example, the profile of the front end from the top surface (extending down to the bottom surface of the embodiment resempling “P” in prone position of the invention) can have other shapes, such as oval, rhombus-like, hexagonal, octagonal, rectangular or square-like. On the other hand, the sides and/or surfaces of the invention need not be flat but may assume other forms such as corrugated or other surface shapes common to bed mattresses. Those skilled in the art will appreciate that various adaptations and modifications of the just described invention can be configured without departing from the scope and spirit of the invention. Accordingly, the scope of the invention should be determined not by the embodiments illustrated but by the spirit of the invention, and the appended claims and their legal equivalents.
