DETAILED DESCRIPTION

Reference will now be made in detail to some specific examples of the present disclosure including the best modes contemplated for carrying out the present disclosure. Examples of these specific embodiments are illustrated in the accompanying drawings. While the present disclosure is described in conjunction with these specific embodiments, it will be understood that it is not intended to limit the present disclosure to the described embodiments. On the contrary, it is intended to cover alternatives, modifications, and equivalents as may be included within the spirit and scope of the present disclosure as defined by the appended claims.

For example, the techniques of the present disclosure will be described in the context of particular interlocking parts or physical compositions. However, it should be noted that the techniques of the present disclosure apply to various other parts or compositions. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present disclosure. Particular example embodiments of the present disclosure may be implemented without some or all of these specific details. In other instances, well known process operations have not been described in detail in order not to unnecessarily obscure the present disclosure.

As used herein, the term “tip” will be used interchangeably with “pointed geometry.” As used herein, the term “tool” will be used interchangeably with “device.” As used herein, the term “massage,” is used interchangeably with “trigger point release.”

Various techniques and mechanisms of the present disclosure will sometimes be described in singular form for clarity. However, it should be noted that some embodiments include multiple iterations of a technique or multiple instantiations of a mechanism unless noted otherwise. For example, a device has a tip in a variety of contexts. However, it will be appreciated that a device can have multiple different tips while remaining within the scope of the present disclosure unless otherwise noted. Furthermore, the techniques and mechanisms of the present disclosure will sometimes describe a connection between two entities. It should be noted that a connection between two entities does not necessarily mean a direct, unimpeded connection, as a variety of other entities may reside between the two entities. For example, a tip may be connected to a base, but it will be appreciated that a variety of extension portions, arms, connectors, bridges, and other features or elements may reside between the tip and the base. Consequently, a connection does not necessarily mean a direct, unimpeded connection unless otherwise noted.

Aspects of the disclosure relate to a massage device usable to stimulate or apply compression to, for example, a portion of muscles or muscle groups.FIGS.1A-1Bshow front and back illustrations of a simplified muscular system, in accordance with embodiments of the present disclosure.FIGS.1A-1Bsimply show some example muscle groups that can be affected by pressure, pain, and/or discomfort, to which techniques and devices disclosed herein aim to alleviate. For example, the techniques and devices disclosed herein can be used to alleviate pressure or pain in the gluteus maximus, pectorals, quadriceps, and hamstrings. The images inFIGS.1A-1Bare common knowledge, are provided for reference purposes only, and can be found on the Internet, for example at:https://www.cabarrus.k12.nc.us/site/handlers/filedownload.ashx?moduleinstanceid=68833&d ataid=265555&FileName=Muscles%20-%20Workbook.pdf.

One example muscle or muscle group which often suffers from pressure is the iliacus muscle. The iliacus muscle is one of the composite muscles that make up the iliopsoas muscle group. The iliopsoas muscle originates from the lumbar vertebrae and discs and then inserts though the femur, and any structure from the lumbar spine to the femur may be affected directly by the iliopsoas muscle group and more specifically the iliacus muscle. Further, various major nerves, such as the femoral nerve and the obturator nerve, also pass through the iliopsoas muscle group and/or the iliacus muscle. Accordingly, any of these innervated structures may be affected by the iliacus muscle. For example, tightness of the iliacus muscle may cause chronic or recurrent pain in any one of the lower abdomen, groin, buttocks, legs, hip joint, sacroiliac joint, lower back, iliac crest, and/or many other regions of the body.

As with many muscles, the iliacus muscle may tighten or shorten due to various external and/or internal factors. As with many muscles, massaging and/or providing localized pressure to or “releasing” the iliacus muscle may help to relax or loosen the muscle and/or reduce pain associated with tightness and/or shortening of the muscle. However, because the iliacus arises from the medial side of the femur bone and also from the inner surface of the ilium bone of the pelvis, portions of the muscle may be difficult to access by a therapist and/or physician. Further, the affected individual may wish to be able to compress and/or massage their own iliacus muscle(s) without the need for assistance from others.

With the aforementioned benefits in mind, aspects of the disclosure relate to a massage device usable to provide localized pressure to the iliacus muscle.FIGS.2A-2Care diagrams illustrating one example of how a device can alleviate pressure or pain in the iliacus muscle, in accordance with embodiments of the present disclosure. Example aspects of the massage device in accordance with aspects of the present disclosure are described throughout the specification. In the interest of clarity, not all possible features of an actual implementation are described in this specification. It will of course be appreciated that in the development of any such actual implementation, numerous implementation-specific decisions must be made to achieve the developer's specific goals, such as compliance with system-related and business-related constraints, which will vary from one implementation to another. Moreover, it will be appreciated that such a development effort might be complex and time-consuming but would nevertheless be a routine undertaking for those of ordinary skill in the art having the benefit of this disclosure.

FIG.2Ashows a device200applying force220to an iliacus muscle232of person230. InFIG.2A, force220is first applied perpendicular to both the ground210and iliacus muscle232. This is because often times, the iliacus muscle requires directed pressure to get relief. Thus, to be most effective, pointed pressure must be applied normal to the face of the iliacus.FIG.2Billustrates that a normal force with a perpendicular angle222to ground210is applied to the iliacus muscle in order to provide relief. In some embodiments, for optimal relief, pressure needs to be applied normal to the face of the iliacus. However, due to the curved nature of the pelvic bone, a force must be applied at an inward angle224in the pelvic area, as illustrated inFIG.2C.

Often times, applying this normal force at an inward angle requires the assistance of someone else, e.g., a therapist. However, in cases where assistance is not available, a tool200is necessary to self-administer this pressure. In some embodiments, to self-administer this pressure, the user may have to use his/her own body weight to apply the high forces necessary for effective therapy, as shown inFIGS.2B and2C. In some embodiments, it is often difficult to self-administer the pressure in the proper location and direction simply by lying directly on a static pointed object, at an angle similar to angle222shown inFIG.2B.

Consequently, to effectively self-administer the pressure to the iliacus muscle, movement is needed. Thus, in some embodiments, to achieve a high force in the proper angle, the tip of device200and user230have to move relative to each other after user230applies his/her body weight onto device200. In some embodiments, device200is a pointed object that translates through space into the body after user230lies on it. In other embodiments, device200remains static but allows user230to shift relative to the pointed tip of device200once user230lies on device200. Because a static device that allows the user to shift requires more effort on the part of the user, it may be preferable to some users to have a pointed object that translates through space. In some embodiments, a combination of both options can also be effective for some users.

AlthoughFIGS.2A-2Cillustrate a device200being applied to iliacus muscle232, device200can be applied to an muscle group that feels pressure, tension, or pain, and can benefit from self-administered trigger point release. As previously mentioned, there can be many variations to the structure of device200. Some of the variations are described in detail with reference to the remaining figures. However, while the remaining figures illustrate some variations or implementations, they do not represent an exhaustive set of configurations for a device in accordance with the techniques and mechanisms disclosed herein. For example, different elements of different figures can be combined in ways not described in this disclosure and still fulfill goal of self-administering trigger point release to muscles or muscle groups. In addition, partially or entirely new configurations not mentioned can also fall under the scope of the present disclosure as long as the goals of effective self-administered trigger point release are met. Various embodiments are described in detail below.

FIGS.3A-3Billustrate a two dimensional view of a simple example massage device, in accordance with one or more embodiments of the present disclosure.FIGS.3A-3Billustrate a simple example of a pointed object, or device,300translating through space. Pointed object300includes pointed geometry, or tip,308, a rotatable extended portion302coupled to tip308, and a pivot304at the base of extended portion302. In some embodiments, extender302is wider at the base than at the tip. In some embodiments, extended portion302connects pointed geometry308and pivot304together in a triangular fashion (from just a one-sided view), similar to an isosceles triangle, with pointed geometry308at the top of the triangle, pivot304being one of the bases of the triangle, and a standing leg303extending from extended portion302at the other base of the triangle. In some embodiments, in addition, to translating through space into the body, force also needs to be applied along the correct vector306. One way to get the device to translate through space and apply force along the correct vector is by having pointed object300rotate about pivot304.

One method for using pointed object300is described below. First, device300is placed on a fixed surface, such as the ground, as illustrated inFIG.3A. Next, the user lies on top of device300, with the pointed geometry, or tip,308contacting the body of the user a muscle, such as the iliacus muscle, in a manner similar to what is shown inFIG.2B. Then, by rotating pointed geometry308into the muscle as the user applies body weight on top, a high force306can be applied in the proper angle against the muscle.FIG.3Bshows how tip308can be moved and angled properly via rotation of extended portion302around pivot304.

FIGS.3A-3Bshow a simple massage device, in accordance with embodiments of the present disclosure.FIG.4illustrates a more complicated device.FIG.4shows a three dimensional view of an example massage device with a handle, in accordance with one or more embodiments of the present disclosure.FIG.4illustrates essentially the same device as inFIG.3A, but with an added lever arm410and handle412. In some embodiments, lever arm410and handle412are added to help give the user leverage for creating the rotation of the pointed geometry408. During usage, when lying on pointed geometry408, the user can push handle412downward to force extended portion402of device400to rotate about pivot404, thereby forcing tip408into his/her muscle and apply pressure in the intended location and angle.

As exemplified inFIG.4, lever arm410is connected to pivot404on the surface of pivot404on the opposite side of the standing leg403. The lever arm extends laterally and vertically at an angle from the ground, ending in the handle. In some embodiments, the handle is connected to the lever arm at a separate angle from the angle formed from the lever arm and the ground. In some embodiments, the handle is specifically shaped in an ergonomic grip for a user's hand. It is worth noting that the pivot displayed inFIG.4demonstrates the cylindrical nature of the pivot inFIGS.3A and3B, which was not shown due to a two dimensional perspective. However, in some embodiments, the pivot need not be a cylinder, but rather any three-dimensional shape that allows for at least partial rotation about the pivot.

FIG.5illustrates a modification toFIG.4.FIG.5shows an example device500with a handle512and a weight503, in accordance with embodiments of the present disclosure. InFIG.5, weight503can be added to the front side of device500to prevent it from rotating toward the handle when in a resting position. In this example, “front side” refers to the side where the standing leg would have been, opposite of lever handle512. Weight503serves as a counterbalance to lever handle512and lever arm510. The remaining portions of device500, e.g., pointed geometry508, extended portion502, pivot504, are the same as the analogous features inFIG.4.

In some embodiments, the weight of handle512and lever arm510needs to be at most40% of the weight of device500. In addition, handle512and lever arm510would ideally be made of strong enough material to withstand the downward force or pressure (material: metal, polycarbonate, etc.) exerted on it by the user.

In some embodiments, the length cannot be much shorter than about9inches for certain muscle groups, such as the iliacus, in order to provide enough room for a person to grab and press down. However, different lengths are required for different muscle groups.

In some embodiments, lever arm510needs to be positioned at a large enough angle to give sufficient room to push down such that the tip rotates the differential distance between the tip in neutral and the surface of the bone that needs to pin the muscle against.

As shown inFIG.5, in some embodiments, pivot504is a smooth cylindrically shaped pivot with circular cross-sections. A cylindrically shaped pivot allows for smooth rotation about the pivot for ease in angle adjustments and rotation. However, in some instances, differently shaped pivots can be used to achieve different rotational functions.FIGS.6and7illustrate various examples of different shaped pivots, in accordance with one or more embodiments of the present disclosure. As with any other part of the device, the pivot also can be removable and swappable with other pivots, enabling various types of rotation pathways. According to various embodiments, round, flat, or pointed geometries give different translation/rotational motions, and therefore different user experiences.FIG.6illustrates a pivot with a polygonal prism shape. A polygonal prism is similar to a cylinder, except the instead of circular cross-sections, the cross-sections of a polygonal prism is the shape of a particular polygon. For example, pivot604of device600can be an octagonal prism, with octagonal shaped cross-sections. The other portions of device600, such as the lever arm610, the handle612, the extended portion602, the pointed geometry608, and the weight603, are coupled to pivot604such that the other portions are attached perpendicular to the length of the polygonal prism (i.e., parallel to the plane of a single cross-sectional slice of the polygonal prism). In such embodiments, the flat “edges” of the polygon prism allow for discretized/quantized “stages” of rotation. In addition, the edges allow for more controlled rotation around the pivot. In such embodiments, it may be desirable to “hold” the device at a certain point, or edge, in the translational movement, which would be more easily accomplished with a flat side in the pivot. However, such embodiments do not have the same flexibility as the cylindrical pivot as shown inFIG.5.FIG.7illustrates yet another polygonal prism shaped pivot.FIG.7illustrates a device700with a triangular prism shaped pivot704, or a pointed pivot shape. Such embodiments may be useful for users who need more extreme rotation, leading to more torque and/or faster translational movement of the pointed geometry. In such embodiments, the rotation of the device is limited to two positions: upright and laying on the flat side of the pivot. The remaining portions of device700, such as the lever arm710, the handle712, the extended portion702, the pointed geometry708, and the weight703, remain the same.

As with the pivots, other parts of the device shown inFIG.5can also be swapped out for variation. According to various embodiments, different tip types can be pointed, curved, domed, or even spring-loaded.FIGS.8-10illustrate devices with different pointed geometries. More specifically,FIG.8illustrates a device800with a spring-loaded bulb coupled to the pointed geometry808. Device800depicts pivot804as a cylindrical pivot, much like pivot504ofFIG.5. The other remaining portions, such as the lever arm810, the handle812, the extended portion802, and the weight803, remain the same. In some embodiments, pointed geometry808to be coupled to a spring-loaded bulb to help dampen forces in case a hardened tip is too painful for some users or exerts too much pressure to a sensitive area, such as the groin. In addition, different types of materials can be used to provide different levels of hardness. In some embodiments, the pointed geometry can comprise materials including, but are not limited to plastic, rubber, silicone, foam, and cloth.

As shown inFIG.8, the pointed geometry can be removable and swappable with other tips, enabling various geometries, heights, durometers, and friction coefficients to be used with the device. This allows the tool to accommodate a broader spectrum of body types and applications for different muscle groups.FIG.9shows an example device900with a handle912, a lever arm910, a pointed geometry908, a pivot904, an extended portion902, and a weight903, in accordance with embodiments of the present disclosure.FIG.9demonstrates a device with a curved or bent pointed geometry908. The rest of device900remains the same as device800, e.g., with the same pivot, handle, lever arm, extended portion, and weight. However, as demonstrated inFIG.9, bent pointed geometry908is angled in the direction of the lever arm. This allows pressure to be applied at a more extreme inside angle toward the bone for certain muscles located along bones that are angled inside, e.g., the pelvic bone. AlthoughFIG.9demonstrates an angle directed toward the lever arm, other embodiments can have the pointed geometry directed toward any direction to accommodate for different bone/muscle angles. For example, pointed geometry908could be bent towards the direction along the length of the cylindrical pivot (e.g., 90 degrees rotated/swiveled to the right or left relative to the direction shown inFIG.9) or toward the weight portion of the device (e.g., 180 degrees rotated/swiveled to the right or left relative to the direction shown inFIG.9). In some embodiments, pointed geometry908can be bent in any angle desired to fit the needs of the user, e.g., for different muscle groups. In some embodiments, pointed geometry908can be adjustable by the user. In such embodiments, pointed geometry908needs to be able to lock in the desired position using a locking mechanism (not shown).

FIGS.10A-10Billustrate an example of a massage device with an adjustable pointed geometry, in accordance with one or more embodiments of the present disclosure. According to various embodiments, for more versatility, device1000includes a single pointed geometry1008that is adjustable. The other remaining portions of device1000, such as the lever arm1010, the handle1012, the extended portion1002, the pivot1004, and the weight1003, remain the same. In some embodiments, degrees of adjustability for pointed geometry1008can include rotational, height adjustment or a combination thereof. In the upright position, pointed geometry1008points straight up, similar to pointed geometry508inFIG.5. InFIG.10A, pointed geometry1008is originally pointed up, but is then rotated toward the direction of the weight, away from the handle. Although the direction of rotation is demonstrated to be toward the weight, it should be noted that the pointed geometry can also be rotated toward the handle or in any direction desired.FIG.10Billustrates pointed geometry1008having rotational and linear movement. Pointed geometry1008illustrated inFIG.10Ballows for linear movement in the vertical direction, thereby extending the height of the pointed geometry, as well as rotational movement demonstrated inFIG.10A. According to various embodiments, adjustable portions include locking mechanisms (not shown) to lock adjustments in place.

As mentioned above, pointed geometries can be straight or bent in various directions for different angles and functional purposes. Similarly, in some embodiments, devices can have adjustable handles as well.FIGS.11A-11Billustrate an example of a massage device1100with an adjustable handle1112, in accordance with one or more embodiments of the present disclosure. According to various embodiments, for more versatility, handle1112can be made to be adjustable. In some embodiments, degrees of adjustability can include translational, rotational (along various axes), or a combination thereof.FIG.11Aillustrates device1100with a pointed geometry1108, extension portion1102, pivot1104, and weight1103, all of which are similar to analogous features of device500inFIG.5. However, the lever arm1110and handle1112are configured in a way such that either lever arm1110or handle1112can be extended linearly, thereby allowing for translational movement. In addition, in some embodiments, handle1112can also be rotated or bent in various directions. In the example inFIG.11A, lever arm1110includes an extension mechanism1111coupled to handle1112such that handle1112can be pulled along the length of lever arm1110. Extending lever arm1110allows for adjustments made for larger users.FIG.11Billustrates device1100with lever arm1110being extended and handle1112being rotated upward.FIG.11Bdemonstrates rotational movement in handle1112, thereby changing the angle handle1112makes with lever arm1110. This rotational functionality allows for a different grip, as well as added leverage. AlthoughFIG.11Ademonstrates extension mechanism1111at the point of attachment with handle1112, in some embodiments, extension mechanism1111can be integrated anywhere along lever arm1110, including the point of connection with pivot1104. Similarly, althoughFIG.11Bdemonstrates handle1112rotating upward, in some embodiments, handle1112can also rotate in any direction desirable to the user. According to various embodiments, adjustable portions include locking mechanisms (not shown) to lock adjustments in place.

In addition, to adjustable handles, various embodiments of the present disclosure also include different shapes of handles for a variety of purpose.FIGS.12and13illustrate various examples of different shaped handles of a massage device, in accordance with one or more embodiments of the present disclosure. As with different pointed geometries, different handles can be used to accommodate different users as well.FIG.12illustrates a device1200with a curved handle1212, which may be softer, more flexible for users with weaker wrists. Device1200includes pointed geometry1208, extension portion1202, pivot1204, lever arm1210, and weight1203, all of which are similar to analogous features of device500inFIG.5.FIG.13illustrates a device1300with an enclosed circular handle1312. This allows for an easier gripping of the handle, in addition to reduce the chances of slipping off the handle while exerting force. In addition, the circular shape of handle1312allows for different grip angles to allow the user to use a grip that is most comfortable for the user. As with device1200, device1300includes pointed geometry1308, extension portion1302, pivot1304, lever arm1310, and weight1303, all of which are similar to analogous features of device500inFIG.5. As with the different types of pointed geometries, as described above, the handles also can be removable and swappable with other handles, enabling various ergonomic grips to be used with this device. This allows the tool/device to accommodate a broader spectrum of body types and applications. According to various embodiments, different handle types can be rigid, compliant, open or closed. As demonstrated herein, each device inFIGS.12and13displays a lever arm, standard pointed geometry, extended portion, a cylindrical pivot, and a weight. However, the different handles can be mixed and matched with any pointed geometry or pivot disclosed herein, or can be paired with or without various types of weights.

The previous figures all describe various shapes for different parts of a massage device in accordance with embodiments of the present disclosure.FIGS.14A-14Millustrate a detailed example of an exemplary embodiment of a massage tool/device in accordance with the present disclosure.FIG.14Aillustrates a three dimensional perspective view of an example massage device1400, showing front, left, and top perspective views. Device1400includes pointed geometry1408, extension portion1402, pivot1404, weight1403, handle1412, and lever arm1410. Pivot1404is a cylindrical pivot to allow for ease of rotation around the length of the pivot. Weight1403is a flat heavy square piece to weigh down device1400while in the neutral stand up position. The flat square shape of weight1403increases the surface area in contact with the ground, thereby increasing the static friction to help stabilize device1400. Pointed geometry1408is curved/bent in order to increase the angle of the application of the force. Extension portion1402has a concave curve on each side of extension portion1402, i.e., the side proximate to lever arm1410and the side proximate to weight1403. The concave curvature of each side allows for maximum clearance for surrounding body tissue that may fold around extension portion1402during engagement of pointed geometry1408with the target muscle group. As demonstrated inFIG.14A, lever arm1410and handle1412are fused into a single curved piece for grip flexibility and maximum leverage.FIG.14Bpresents a two dimensional left side view of device1400.

FIG.14Cis a two dimensional left side view of device1400demonstrating one angle of curvature of lever arm1410.FIG.14Cshows lever arm1410making an angle1414with ground1416. Angle1414represents how much device1400can rotate before lever arm1410hits ground1416, causing the rotation to come to a hard stop. In some embodiments, angle1414is 35 degrees. The 35 degree of angle1414was determined through experimentation to maximize rotation for use with certain muscle groups, such as the iliacus muscle, while still maintaining sufficient clearance space for handle1412. However, in other embodiments, the angle can vary depending on the particular muscle groups targeted.

FIG.14Dillustrates device1400being rotated the full 35 degrees about pivot1404. As shown inFIG.14C, angle1414between lever arm1410and ground1416is approximately 35 degrees, in this particular example. Thus, during a full rotation about pivot1404, pointed geometry1408also rotates at approximately a 35 degree angle1418, which is equivalent to angle1414. It should be noted that in one particular embodiment, the horizontal translational distance1420traveled by pointed geometry1408during rotation is 47 mm, while the vertical translational distance1422traveled by pointed geometry1408during rotation is 13 mm. Massage device1400was particularly designed in order for pointed geometry1408to move 47 mm horizontally and 13 mm vertically. These numbers were derived empirically through much experimentation and found to give the average human body the most therapeutic relief while minimizing discomfort. However, it should be noted that many other embodiments for massage device1400can also be possible to achieve different translational distances both horizontally and vertically, in order to accommodate larger or smaller bodies, as well as different muscle groups that require larger or smaller angles of rotation.

FIG.14Edepicts device1400after a full rotation about pivot1404. Although handle1412and lever arm1410are fused together in device1400,FIG.14Eillustrates the difference in the sectioning of handle1412and lever arm1410. As previously mentioned inFIG.14C, lever arm1410is angled at approximately 35 degrees from ground1416. In addition, in some embodiments, handle1412has an additional angle of deviation away from lever arm1410.FIG.14Eillustrates handle1412curving away from lever arm1410towards pointed geometry1408at an angle1424. Angle1424allows for handle1412to still have enough clearance for a user's hand even after fully rotating device1400the entirety of angle1414, meaning a portion of lever arm1410is in contact with ground1416. In the example given inFIG.14E, given a minimum horizontal clearance length of 80 mm, the minimum vertical clearance height of a location on handle1412that is 80 mm from the tip of handle1412is 15 mm. Once again, these numbers are derived empirically for the average human body through repeated experimentation. In the example given inFIG.14E, the additional angle1424that gives the minimum distances is approximately 18 degrees. However, it should be noted that the actual value of angle1424, as well as the values of minimum distances1426and1428, can vary depending on the user and the type of muscle group targeted.

FIG.14Fillustrates the angle at which pointed geometry1408is bent. In some embodiments, pointed geometry1408is originally bent at an angle1430from the vertical. This is because many muscle groups, such as the iliacus muscle, are already oriented at an angle when the user is facing directly toward the ground. In this example, angle1430is approximately 35 degrees, which was empirically derived through experimentation to give the angle that encounters many commonly targeted muscle groups, i.e., muscle groups that are not perpendicular to the vertical when the user is facing the ground. As with the other angles described above, the actual value of angle1430can vary depending on the muscle group being targeted.FIG.14Falso shows rotated angle1432, which represents the angle that pointed geometry1408makes with the vertical after a full rotation about pivot1404. In this example, since the angle1414of lever arm1410is approximately 35 degrees, the value of angle1432is approximately 70 degrees from the vertical.

FIGS.14G-14Hillustrate how weight1403of device1400is designed to shift the center of mass of device1400to a low position opposite handle1412. As shown inFIG.14G, weight1403shifts the center of mass (CM) to position1434with a height1436and a distance1438from the center of pivot1404on the side that is opposite of handle1412. In this example, CM height1436is approximately 20 mm and CM distance1438is approximately 22 mm from the center of pivot1404. In some embodiments, having the CM in location1434is necessary to ensure that the weight of device1400(not to be confused with weight1403) is always working to force device1400to sit on weight1403, even when device1400is fully rotated back to the floor, as demonstrated inFIG.14H. In such embodiments, having device1400always trying to reorient itself to the default position, i.e., the standing upright position, helps with the stability of device1400, especially during usage. As with other numbers explicitly given above, CM position1434, with CM height1436and CM distance1438, was derived empirically through experimentation. CM position1434can have different height and distance values, as long as it allows device1400to constantly want to reorient back into the default position.

As previously mentioned, in some embodiments, extension portion1402of device1400is concave on both sides. The reason for this curvature on both sides is to make room for the user's body when in contact with pointed geometry1408of device1400.FIG.141illustrates the radius of curvature for both sides of extension portion1402. In the example, the radius of curvature1440of the side of extension portion1402closer to handle1412is 29 mm. The radius of curvature1442of the side of extension portion1402closer to weight1403is 47 mm. As with other numbers explicitly given in the present disclosure, radii of curvature1440and1442were derived empirically through much experimentation in order to implement a design for massage device1400that gives sufficient room for the average body to use device1400without fear of excess body tissue getting in the way and impeding full utilization of device1400. The actual value of the radii can vary depending on the size and body type of the user.FIG.14Jillustrates device1400in default position with pointed geometry1408in contact with body tissue1490of a user. InFIG.14J, excess body tissue portion1492folds over bent pointed geometry1408during contact with body tissue1490. However, as illustrated inFIG.14J, the gap caused by the concave shape of the sides of extension portion1402prevent the excess body tissue portion1492from touching the rest of device1400, thereby preventing excess body tissue portion1492from impeding full rotation of device1400.FIG.14Killustrates device1400in full rotated position with pointed geometry1408in contact with body tissue1490of a user. As demonstrated inFIG.14K, the gaps or pockets created by the concave nature of both sides of extension portion1402allow for excess body tissue portion1492from hitting the sides of extension portion1402, thereby preventing excess body tissue portion1492from counteracting against the full rotation of device1400.

As described above, the numbers for angles, heights, and distances were all derived empirically during discovery of the “best” design for a massage device.FIG.14Lillustrates a few more measurements that were meticulously derived through experimentation in order to achieve one embodiment of an ultimate massage tool/device. Device1400ofFIG.14Lincludes a height1444from the bottom of weight1403(or ground1416) in default position to the top of pointed geometry1408(in default position). In addition, device1400includes height1446, which is the height from the top of pointed geometry1408to the top/tip of handle1412. Last, device1400also includes distance1448, which is the horizontal distance between the top of pointed geometry1408to a point on handle1412at the same height as the top of pointed geometry1408. In this example, height1444is approximately 98 mm, height1446is approximately 67 mm, and distance1448is approximately 120 mm. Height1446and distance1448were empirically derived while searching for the best ergonomic fit for an average human body, while maintaining a compact design. Height1444was empirically derived while trying to find the right amount of pressure when a user initially lies on device1400. During experimentation, taller heights were found to be too painful for users and shorter heights did not provide enough pressure for effective treatment. However, as with all numbers explicitly given in the present disclosure, the numbers provided in reference toFIG.14Lare just one set of numbers for describing device1400. Other values for heights1444and1446, as well as distance1448, can be used depending on the size of the individual or the type of muscle group targeted.

Although there are many ways to design an embodiment of massage device1400,FIG.14Mdemonstrates just one example of component parts that make up an exemplary embodiment of device1400. More specifically,FIG.14Mshows an exploded view of an example embodiment of device1400. Pointed geometry1408can be made up of two pieces, outer shot1450and inner shot1452. Outer shot1450is made of a rubber material which adds comfort to the user upon contact. In some embodiments, outer shot1450need not be rubber, but would preferably be a material that is flexible and compliant in order to alleviate direct pressure when in use. By contrast, inner shot1452comprises a harder material such as acrylonitrile butadiene styrene (ABS), or some other plastic material. The important feature of inner shot1452is that it should probably be made of a firmer, stiffer material in order to maintain the integrity of the pointed geometry's form during usage.

In some embodiments, extension portion1402comprises two different pieces of polycarbonate material, upper piece1454and lower piece1460. Each of the pieces of extension portion1402should comprise a stiff material, such as polycarbonate, or other lightweight but strong material. Metal can also be used for these pieces, but the weight1403would need to be much heavier in order to keep the CM low and opposite side of pivot1404. Upper piece1454and lower piece1460also form lever arm1410and handle1412. The two pieces can be joined by screws1462. In some embodiments, optional middle pieces1456and1458can be inserted in between upper piece1454and lower piece1460in order to increase the durability of the relative sections that the middle pieces are supporting.

Device1400also includes pivot1404, which is comprised of a cylindrical piece1464bolted to lower piece1460by screws1466. As demonstrated inFIG.14M, cylindrical piece1464need not be a fully formed cylinder, as long as a “frame” of a cylinder is sufficiently present to allow device1400to rotate about pivot1404. In some embodiments, cylindrical piece1464also comprises a polycarbonate material.

Last, device1400also includes weight1403. InFIG.14M, weight1403is comprised of strong, sturdy, and heavy material because it serves as the counterweight to handle1412, lever arm1410, and pivot1404. In some embodiments, weight1403comprises a bulk piece1468, which is bolted to lower piece1460with screws1472. In some embodiments, bulk piece1468is stainless steel, or another sturdy and heavy material, such as a metal, in order to shift the CM toward weight1403. While bulk piece1468need not be metal, ideally it should be a material that is much heavier than the material that comprises upper piece1454and lower piece1460. In some embodiments, weight1403also comprises optional friction pad1470, which is ideally made of a material with a high coefficient of friction, such as rubber, to prevent slipping and increase stabilization of device1400during usage. It should be noted that the component parts explicitly described with reference toFIG.14Mare just one combination of component parts that can make a massage tool/device in accordance with embodiments of the present disclosure. It should also be noted that any combination of the parts described above along with any other parts described, or even not described, throughout the present disclosure can be combined to form a massage device in accordance with the present disclosure, as long as it can be used to provide trigger point or pressure release of a muscle or muscle group.

FIGS.14A-14Millustrate only one example of a massage device, in accordance with embodiments of the present disclosure.FIGS.15A-18Cillustrate other example variations of a massage device, in accordance with embodiments of the present disclosure. According to various embodiments, for more versatility, the pivot position can also be made to be adjustable.FIGS.15A-15Cillustrate a device1500with an adjustable pivot1504. In some embodiments, by enabling different pivot positions, the user can experiment with various torques, final positions, and travel amounts for ideal treatment. Device1500includes lever arm1510, handle1512, weight1503, extended portion1502, pivot1504, and pointed geometry1508. InFIG.15A, pivot1504is an adjustable joint, rather than a geometric shape over which the other portions rotate. Pivot1504is also a rotatable joint configured such that lever arm1510can rotate up and down around pivot joint1504thereby applying translational motion to pointed geometry1508.FIG.15Billustrates device1500demonstrating an adjustable height for pivot1504, thereby adjusting the height of pointed geometry1508.FIG.15Cillustrates device1500rotating about pivot joint1504while in the elevated state.

FIGS.16A-16Cillustrate examples of various bases of example massage devices, in accordance with embodiments of the present disclosure. The devices depicted in these examples contain only a base, an extension piece, and a rounded tip. The simpler designs ofFIGS.16A-16Cmay be desirable in some cases where smaller size of the device is desirable. Each device includes pointed geometry1608and extension portion1602. The devices can be constructed with different shapes for the bottom of the base. The shapes can be flat, rounded or notched where it touches the ground.FIG.16Adepicts device1600with a flat base1604. This embodiment has great stability, but does not allow for rotation about a pivot. Device1600may be useful for releasing muscles that can be directly accessed without the needed for added rotation, or for users that can add their own rotation by contorting parts of their body.FIG.16Bdepicts device1620with a rounded base1624. Base1624is similar to cylindrical pivot504inFIG.5.FIG.16Cshows device1640with a notched base1644. Base1624is similar to polygonal prism pivot604inFIG.6. As with the devices depicted inFIGS.5and6, the devices inFIGS.16B-16Care designed to rotate or “roll” over the base, thereby providing translational movement to rounded tip1608and extension portion1602. The examples depicted inFIGS.16A-16Care just a few examples of simplified designs for a muscle pressure release tool. The vital aspect of the shapes in these examples is that a tip is attached to a base that is either stable or movable and that can be placed on the ground.

FIGS.16A-16Cillustrate examples of simple embodiments with varying bases. In some embodiments, the size and shape of the tip for simple embodiments can vary as well.FIGS.17A-17Dillustrate examples of various tips of example massage devices, in accordance with embodiments of the present disclosure. These figures illustrate the various different tip shapes for a simplified massage tool design. Each device includes an extension portion1702and a curved base1704. However, the shapes and sizes of the pointed geometries can vary for different functions. For example,FIG.17Aillustrates device1700with a spherical pointed geometry1708. Spherical tip1708is similar to tip1608inFIGS.16A-16C.FIG.17Bshows device1720with a pointed tip1728. Pointed tip1728is similar to pointed geometry508inFIG.5.FIG.17Cshows device1740with an elliptical tip1748. Elliptical tip1748is like a bent version of rounded tip1708, for usage against a muscle at a more extreme angle.FIG.17Dshows device1760with a hook-like tip1768. Tip1768is similar to bent pointed geometry908inFIG.9. The various shapes for the tips are designed with the intention of creating a surface that will contact the body to apply pressure to various muscle groups. As withFIGS.16A-16C, the examples depicted inFIGS.17A-17Dare just a few examples of simplified designs for a muscle pressure release tool.

In some embodiments, the angle which the tip is attached relative to the base for a simple design can vary as well.FIGS.18A-18Cillustrate examples of various angles for extended portions of massage devices, in accordance with embodiments of the present disclosure. Each device includes a rounded tip1808and a curved base1804. However, each device demonstrates an example variation of the angle at which the extended portion is attached to the base. For example,FIG.18Ademonstrates device1800with an almost perpendicular angle between extension portion1802and the bottom of base1804.FIG.18Bdemonstrates device1830with a narrower angle between extension portion1822and the curved portion of base1804.FIG.18Cdemonstrates device1840with a wider angle between extension portion1842and the curved portion of base1804. While the examples illustrated in all the figures above show particular combinations of features/elements of devices, it should be noted that any combination of parts, portions, features, or elements from any combination of the figures can also be mixed and matched to achieve an embodiment in accordance with the present disclosure. These examples are all designed with the function of being able to apply pressure to the muscle by either moving the tool into the body or moving the body on the tool.
