## Background
CROSS-REFERENCE TO RELATED APPLICATION
This application claims the benefit of provisional patent application Ser. No. U.S. 61/000,196 filed Oct. 25, 2007 by the present inventors, which is incorporated by reference.


BACKGROUND OF THE INVENTION
The invention relates to a massaging device, and more particularly, to a personal, manual massaging device for appendage muscles comprised of a wrap, wherein the wrap having vertical edges separated by a gap is bound by at least one tension transfer member enclosed by internal and external tension-transfer guides, the tension transfer member is encircled with springs between the vertical edges, and the external tension-transfer guide is connected to an actuator, and a method of massaging appendage muscles using the manual device.
Muscle tension is caused from a variety of sources, such as, extreme or fast bodily movement, strain on muscle use, stress, injury or trauma to the body, etc. Muscle tension can also be caused by internal complications such as decreased blood flow, damage to the blood vessel walls, infections or muscular imbalance. No matter the cause, muscle tension can be extremely painful for an individual.
Muscle tension can often feel like the muscles are always tight or strained, sometimes to the point of frequent pain, or even persistent and ongoing pain. Some individuals may also find the pain so restricting and debilitating that it prevents physical activity, and sometimes to the point of becoming bed ridden. Muscle cramps, or muscle spasms, are strong, painful contractions. They can occur in virtually any muscle but are most common in the calf and foot.
Muscle massaging devices to relieve tension are extremely popular, and there are many variations in the marketplace. The vast majority of these devices are for the neck and back. These devices either rest on top of the back or neck muscles or require rubbing an ointment into the skin.
One main solution for relieving muscle tension is to apply pressure to the sore muscle area. This helps relieve throbbing or aching which are often the symptoms of muscle tension. Contracting and expanding of the muscles also helps to increase blood flow through the muscles, thereby allowing the constant contraction of the muscle itself to subside.
The present invention seeks to provide a portable, easy to use device for massaging appendage muscles. The present invention is a low-cost product and allows for multiple embodiments which can allow a user to operate the device either by hand or by foot. The wrap allows the device to be used on a plurality of body parts thereby decreasing ongoing muscle tension.
DESCRIPTION OF THE RELATED ART
Previously, many massaging devices have been introduced that are portable and easy to use, many of which can be found in stores or on websites that sell personal care products. However, especially with the condition called Deep Vein Thrombosis (commonly referred to as Economy Class Syndrome) on the rise, there is a need for a portable, easy to use device for appendage muscles, such as the calf muscle.
One commonly used device for appendage muscles is the compression stocking, which is a static device, as opposed to one which contracts and expands, and thus not a true massaging device.
Another concept is a portable device which works by sending electrical impulses to stimulate the muscle. This, again, is not a true massaging device. It also requires electricity, in the form of a battery, which can be inconvenient for many people, and the device may cost more than someone other than those already afflicted with deep vein thrombosis or at a high risk for this condition may be willing to spend.
Still another concept is a massaging device which requires a bladder filled with liquid or air with a pump to inflate and deflate the bladder at intervals to provide the massaging effect. However, most are cumbersome devices which are not portable and are cost prohibitive except for use in clinical environments. Even those which claim to be portable are so only in a loose definition of the word portable. These are also medical devices, rather expensive, and are primarily for those people already with deep vein thrombosis or those with a high risk of this condition.
SUMMARY OF THE INVENTION

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
FIG. 1 illustrates the massaging device in the preferred embodiment. The massaging device has a wrap 8 made of a soft, flexible material, preferably nylon. It is possible for the wrap 8 to be made of a variety of materials, such as, canvas, polyester, or the like. The wrap 8 can also be made of semi-soft material, such as rubber or leather, or a hard material, such as metal or plastic. For wraps 8 made of soft or semi-soft materials, one or more straight or curved wrap supporters 16 can be attached to the vertical edges 28 of the wrap 8 along the vertical axis to allow for even compression and to prevent the wrap 8 to “pucker” along the vertical edges 28.
The wrap 8 has vertical edges 28 and a gap 26 defined by the vertical edges 28 which allows the wrap 8 to be constricted. The size of the gap 26 is preferably two to three centimeters, but can be varied. The vertical edges 28 of the wrap 8 are bound by a tension-transfer member 10. Preferably, the tension-transfer member 10 is a thin cable, but wire, string, lace, or the like are suitable materials. The wrap 8 is constricted or compressed by one or more of the tension-transfer members 10. The tension-transfer member 10 is enclosed in an external tension-transfer guide 12a and an internal tension transfer guide 12b which are in communication with the wrap 8. The tension-transfer member 10 is encircled by two springs 18 positioned between the vertical edges 28 which allow the wrap 8 to toggle between a constricted and an un-constricted position.
The external tension-transfer guide 12a integrally couples to an actuator 14 and holds the tension between the actuator 14 and the wrap 8. The internal tension-transfer guide 12b integrally couples between the two springs 18 of the tension-transfer member 10 and the anchors 24 located along the vertical edges 28. The internal tension-transfer guide holds the tension between the anchors 24.
In the preferred embodiment, the springs 18 encircle the tension-transfer member 10, however, other positions of the springs between the vertical edges 28 are contemplated. Preferably, the anchors 24 are separate members which hold the external tension-transfer guide and internal tension-transfer guide, 12a and 12b, respectively, in place while allowing the tension transfer-member 10 to move freely. Anchors 24 may be created by other means, such as, glue or sewing, or the like. A protective flap 20 can be positioned between the springs 18 and the skin of the body part of the user so as to avoid abrasions between the skin, pants or the like, of the user and the springs 18.
The actuator 14 is a mechanism similar to a hand-brake and allows the wrap 8 to be either positioned in a constricted or un-constricted state by either compressing the actuator 14 to retract the tension-transfer member 10 and cause the springs 18 to coil or decompressing the actuator 14 and allowing the springs 18 to uncoil and push the wrap 8 back to the open position.
The first step in using the massaging device is placing a body part such as a limb or appendage in the wrap 8 by allowing the gap 26 to be in the open position. Next, by compressing the actuator 14, the tension-transfer member 10 constricts the wrap 8 around the body part by retracting and bringing the vertical edges 28 towards each other and minimizing the gap 26. The user then releases the actuator 14, releasing tension in the springs 18 and in the tension-transfer member 10. As tension is released, the vertical edges 28 are separated and the gap 26 is returned to the open position. The springs 18 push the wrap 8 completely back to its un-constricted position upon release of the actuator 14. These steps are repeated to produce a massaging effect and relieve muscle tension in the desired body part.
FIG. 1B illustrates the external tension-transfer guide 12a and internal tension-transfer guide 12b in the preferred embodiment as hollow sleeves or tubes. Other embodiments are contemplated which allow the tension-transfer member 10 to pass through the external and internal tension-transfer guides 12a, 12b. 
FIGS. 2A-2B illustrate an alternative embodiment of the massaging device in which the external tension-transfer guide 12a is split into two tension-transfer members 10. In this embodiment, each tension-transfer member 10 is encircled by a spring 18 between the vertical edges 28. Each end of the external tension-transfer guide 12a integrally couples to anchors 24 on the vertical edges 28 of the wrap 8. In this alternative embodiment no internal tension-transfer guide is present and the wrap 8 continues to operate as intended to effectively massage appendage muscles.
FIG. 3 illustrates an alternative embodiment of the massaging device in which the internal tension-transfer guide 12b is a solid piece with a groove along the edge to allow the tension-transfer member 10 to slide freely. In this embodiment, the tension-transfer member 10 integrally couples to the anchors 24 located on the vertical edges 28 of the wrap 8, and the compression from the actuator 14 guides the anchor 24 to constrict the gap 26 when in the compressed, closed position. The internal tension-transfer guide 12b can be made of any hard or soft material which does not constrict lateral movement.
FIG. 4 illustrates a further alternative embodiment of the massaging device in which two tension-transfer members 10 are used, each enclosed by an external tension-transfer guide 12a. In this embodiment, the wrap 8 encircles the body part, and the springs 18 are adjacent to the tension-transfer members 10 but integrally couple to the vertical edges 28. The tension-transfer members 10 integrally couple to the anchors 24. In this embodiment the actuator 14 is a flat object which can be operated by the user's foot.
FIG. 5A illustrates an alternative embodiment of the massaging device in which the wrap 8 is slimmer in size. In this embodiment, only one tension-transfer member 10 is contemplated with one spring 18 encircling the tension-transfer member 10. In this embodiment, the wrap 8 has protruding members 22 located on the inside of the wrap 8 to provide the user a deeper massage to relieve muscle tension. The protruding members 22 can vary in number, size and shape to achieve the desired massaging effects.
FIG. 5B illustrates an alternative embodiment of the massaging device with only one tension-transfer member 10 and no external tension-transfer guide 12a or springs 18. The tension-transfer member 10 integrally couples between an anchor 24 on the vertical edge 28 and the actuator 14.
FIG. 6 illustrates an alternative embodiment of the massaging device in which no internal tension transfer guide 12a is contemplated. The tension-transfer member 10 is encased within the wrap 8 between the two springs 18.
In conclusion, presented herein is a manual device for massaging appendage muscles, and a method of using the same. The invention is illustrated by example in the drawing figures, and throughout the written description. It should be understood that numerous variations are possible, while adhering to the inventive concept. Such variations are contemplated as being a part of the present invention.
