1. Technical Field
The present disclosure is directed to non-invasive therapeutic devices for use on muscles, ligaments, and tendons and, more particularly, to a compliant cylindrical roller having deep tissue massage elements formed on an outer surface for selective application by a user.
2. Description of the Related Art
Massaging of muscles, tendons, and ligaments is known to provide therapeutic benefits in overcoming injuries to soft tissues, as well as addressing muscle tightness, lack of flexibility, soft tissue adhesions, knots, and scar tissues. The use of manual massage is also known to maintain good health of these tissues. Countless tools and massage aids have been developed to provide a mechanical advantage and to relieve stress on the hands of the massage provider.
Recently, large scale devices have been utilized, such as a large tube or a ball, in which the weight of the body is applied to the device. By positioning the body in various orientations with respect to the tube or the ball and rolling the body across the device such that the device rolls on a supporting surface, provides the application of greater force to the affected tissue. For example, one known device is nothing more than a tubular roller formed of foam material on which a user balances their body, typically in a reclining position, either on their back, side, or stomach. The roller has a smooth outer surface and is not supported on the ends. Some of these devices have textured surfaces to improve the effect of compressing soft tissue beneath the skin. One such device known as the RumblerRoller® manufactured and distributed by STI in Baton Rouge, La., incorporates bumps that have a firm yet flexible construction for continuously kneading the body. The closely spaced bumps (less than two inches apart) are designed to reduce area contact with the device while increasing pressure to provide a deeper, more penetrating action. The disadvantage of this design is that users cannot selectively position any one of the bumps over a desired area while not having bumps applied anywhere else on the body. Thus, there is a need for a roller massage device that provides for deep tissue massaging in selectable areas of the body without having surrounding tissue so deeply massaged.
The present disclosure is directed to a deep tissue massage device that includes a compliant cylinder formed of compressible material, the cylinder having an external surface with at least one external ridge formed on the exterior surface of the cylinder. The at least one ridge includes a single stem formed on the exterior surface of the cylinder that has a branch portion extending from one end of the stem, the branch portion having two legs.
In accordance with another aspect of the present disclosure, the two legs of the branch portion join back together at a second end of the stem.
In accordance with another aspect of the present disclosure, the two legs form a Y-shaped pattern.
In accordance with another aspect of the present disclosure, the at least one ridge is formed of either a continuous ridge or it is formed of ridge segments
In accordance with another aspect of the present disclosure, the at least one ridge extends 360° circumferentially around the exterior surface of the device.
In accordance with another aspect of the present disclosure, the at least one ridge includes a pair of two opposing Y-shaped ridges placed side-by-side on the exterior surface of the device. Ideally, the pair of opposing Y-shaped ridges are in spaced parallel relationship on the exterior surface of the device.
In accordance with yet a further aspect of the present disclosure, a pair of end ridges or end caps are formed on each end of the cylinder, the end ridges extending from the exterior surface a distance that is equal to a distance that the at least one ridge extends from the exterior surface of the cylinder.
The foregoing and other features and advantages of the present disclosure will be more readily appreciated as the same become better understood from the following detailed description when taken in conjunction with the accompanying drawings, wherein:
In the following description, certain specific details are set forth in order to provide a thorough understanding of various disclosed embodiments. However, one skilled in the relevant art will recognize that embodiments may be practiced without one or more of these specific details, or with other methods, components, materials, etc. In other instances, well-known structures associated with foam rollers have not been shown or described in detail to avoid unnecessarily obscuring descriptions of the embodiments.
Unless the context requires otherwise, throughout the specification and claims which follow, the word “comprise” and variations thereof, such as, “comprises” and “comprising” are to be construed in an open, inclusive sense, that is as “including, but not limited to.”
Reference throughout this specification to “one embodiment” or “an embodiment” means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment. Thus, the appearances of the phrases “in one embodiment” or “in an embodiment” in various places throughout this specification are not necessarily all referring to the same embodiment. Furthermore, the particular features, structures, or characteristics may be combined in any suitable manner in one or more embodiments.
As used in this specification and the appended claims, the singular forms “a,” “an,” and “the” include plural referents unless the content clearly dictates otherwise. It should also be noted that the term “or” is generally employed in its broadest sense, that is as meaning “and/or” unless the content clearly dictates otherwise.
The headings and Abstract of the Disclosure provided herein are for convenience only and do not interpret the scope or meaning of the embodiments.
Referring initially to
Ideally, the ridge pattern 20 includes a first ridge design 22 and second ridge design 24 in spaced parallel relationship around the circumference of the device. Each ridge design includes a single ridge portion 26, shown more clearly in
Ideally, the device core 12 is formed from Ethylene-vinyl acetate (EVA) foam material at a particularly high density for durability and to resist breaking down over time with use. This high density core 12 is structured to provide a strong support to the outer layer 14, which is wrapped around the core 12 as described more fully below. In addition, the high density EVA foam core is structured to resist compression that is exerted on the outer layer 14 by a user.
The outer layer 14, which contains the ridge pattern 20, is made from an elastomer material that is a combination foam/rubber composition. It is very durable and resistant to breaking down over time. In addition, it is a closed cell material, meaning it has a smooth surface that will not capture bacteria and germs as will an open cell foam (which is used for many other types of foam rollers currently on the market).
It is to be understood that the core 12 and the outer layer 14 may be made from other materials. The core may be made from variations of the EVA foam, derivatives thereof using foam or rubber material, plastics, wood, or combinations thereof. In addition the core could include noncompressible material, such as liquid, or a compressible material such as air. Similarly, the outer layer may be formed from variations or derivatives of the elastomer material, or from foam, rubber material, plastics, wood, or a combination thereof. Alternatively, the outer layer 14 may include the use of liquid or air bladders. In accordance with another aspect of the present disclosure, the entire device 12 may be inflatable.
In construction, the EVA core 12 is made from a standard cylinder mold. The outer layer 14 with the ridge pattern 20 is made by initially creating a mold. Once both components 12, 14 are complete, the outer layer 14 of elastomer is wrapped around the inner EVA core 12 and glued in place using known processes and material that will not be described in detail herein.
Turning next to the ridge pattern 20, the particular shape of the pattern is important because it offers a user two options for deep tissue massage. This is possible because of the linear type design of the ridges formed circumferentially around the exterior surface 18 of the device 30. More particularly, the single ridge portion 26 extends partially around the circumference of the exterior surface 18 to provide a single linear area for a user to roll on to. This provides an aggressive deep tissue massage in a specifically targeted location. In contrast, the dual ridges formed by the spaced apart parallel ridges 28 help a user roll two linear areas of soft tissue at the same time. These dual ridges 28 also provide a stabilizing track on which to roll. This can be beneficial in locating a stable starting point that will enable a user to stay on track to roll onto the single ridge 26. The dual ridges 28 also extend at least partially around the circumference of the exterior surface 18.
In the preferred embodiments shown in

It is to be noted that the end ridges 32 have straight or right-angled sidewalls with respect to the exterior surface 18. However, it is possible to form the end ridges 32 to have beveled or rounded sidewalls if desired. These end ridges 32 are designed and structured to provide stability and prevent the roller from tipping during use. In the embodiment where the end ridges 32 are used, there is preferably a three and one-half inch spacing between an outside edge of the spaced parallel ridges 28 and the interior edge of the end ridge 32.
Although the particular pattern of ridges shown and described above is one representative embodiment, additional opposing Y-shaped patterns can be added to the device 10, 30, or different patterns may be used in addition to or in place of the opposing Y-shaped ridge design. This could include a single ridge band partially or completely circumscribing the exterior surface of the device 10, 30. The ridges may also be formed at angles to the longitudinal axis of the cylinder or in a spiral pattern around the outside of the cylinder, although in the preferred embodiment the ridges are as shown and described above. Alternatively, the ridge may be formed in segments such that the ridge is non-continuous. The spacing of the segments would be at a distance that would still present a substantially smooth facing surface that is applied to the user's body.

When using the foam roller device 10, 30 of the present disclosure for myofascia release, direct pressure on connective tissues (fascia) relaxes muscles and soft tissue, resulting in greater overall flexibility and body wellness.
In order to clean the device 10, 30 a user need only use a sanitizing wipe to remove dirt, bacteria, and germs.
Although a preferred embodiment has been illustrated and described it is to be understood that various changes may be made therein. For example, the length may vary between 12 inches and 36 inches. The diameter may be anywhere in the range of four inches to seven inches with a preferred diameter of four and three-quarter inches. The range of angles of the sidewalls 36 can be varied to provide a different width of the crown 34 on the ridges. In addition, a hand-held version can be constructed to include grips or handles on the truncated ends or extending through the device to enable the user to control the amount of compression through the amount of force they exert with their hands and arms.
It is to be understood that in accordance with another aspect of the present disclosure, the at least one ridge is formed of either a continuous ridge or it may be formed of ridge segments in which spaces are formed between the segments. For example, the Y-shaped ridge does not have to be connected to the opposing Y-shaped ridge but instead can be two discrete Y-shaped ridges. In addition, the ridges can be formed of shorter segments arranged to form a single stem ridge as well as a pair of branched ridges, not necessarily linear and not necessarily in a Y shape, but diverging at an angle from each other or at least one diverging at an angel from the stem to create an angled branch. Although the ridges are shown formed tranverse to the longitudinal axis of the cylinder, they can be parallel to or at other than a right angle to the longitudinal axis of the cylinder.
The various embodiments described above can be combined to provide further embodiments. These and other changes can be made to the embodiments in light of the above-detailed description. In general, in the following claims, the terms used should not be construed to limit the claims to the specific embodiments disclosed in the specification and the claims, but should be construed to include all possible embodiments along with the full scope of equivalents to which such claims are entitled. Accordingly, the claims are not limited by the disclosure.
