Description

Cylindrical massage roller and massage set

Technical area

The invention relates to a massage roller, as it is used in the gym as well as in the field of physiotherapy. Such a massage roller has a cylindrical body, usually with a circular profile. The massage roller has a lateral surface and two end faces. As a rule, the lateral surface of the massage roller comes into contact with a body party of a person to be trained or to be treated.

Presentation of the invention

It is an object of the present invention to provide a massage roller that is universally applicable.

According to the invention, the massage roller has a recess on at least one of the front sides, which is designed, in particular, to cooperate with the part of a massage element that is complementary to the recess. The indentation allows a more effective and large-scale adapted fascia treatment of protruding body parts, such as a shoulder. For example, if the massage element is a massage ball, the indentation is spherical with the same or different radius as the massage ball. If the massage element is a cone or contains a cone-like projection, the indentation is cone-shaped. Many other geometries of massage elements are possible, such as spheres, cones, hemispheres, cylinders with a ball or cone extension. By jointly using the massage roller with the massage element surface structures can thus be created, in particular at the transition surface, which allows a larger area and adapted to specific body structures Faszienbehandlung. Alternatively or additionally, the lateral surface of the massage roller, in the axial direction preferably in the middle of the rollers, a circumferential groove or recess. In this way, by the flank regions of the depression, the dissolution of fascial adhesions and adhesions in the bone or spine area of a person can be intensified.

The lateral surface is preferably round in the groove or depression, which makes the handling ergonomic and friendly to the body. The e.g. round shoulders formed by round shoulders brings a more ergonomic shape with it and leads to the fact that no angular edges are formed in the region of the lateral surface of the massage roller, which could lead to pressure points or even injury in use. The axial length u of the transition from the groove or recess into the cylindrical surface of the massage roller is preferably at least 1 5%, in particular 20% and preferably at most 50% of the axial length I of the groove or depression itself. that the transition is very gentle and thus does not penetrate into the tissue. The axial length I of the groove or recess is determined by the distance of the beginning of the curvature of the cylindrical lateral surface in the groove / recess on both sides of the groove / recess. The axial length of the transition u we determined on the one hand by the beginning of the curvature and on the other hand by a change of sign of the second derivative of the surface profile (curvature direction) of the roll at the transition.

The indentation of the massage roller preferably has a depth of at least one third of its radius. In this way it is achieved that the indentation is deep enough to receive a substantial part of the massage element.

By the invention, the massage roller can be used together with one or more massage elements, eg massage balls, resulting in a changed geometry of the entire massage arrangement and thus more diverse applications. Optionally, only one of the end faces can have an indentation or even both end sides. Accordingly, the massage roller can then interact either with a massage element or with two massage elements. Preferably, the massage roller is formed as a one-piece polymer body, which is easy to produce, which is environmentally friendly and energy-friendly, wherein the polymer material is preferably 100% recyclable and free of exhaust gases and / or free of other chemical blowing agents.

Preferably, the polymer body has a certain porosity between 70 and 99% by volume in order to impart greater elasticity to the entire massage roller, the elasticity meaning reversible elasticity. The elasticity of the massager roll is preferably higher than 5%, in particular higher than 10%.

In an advantageous development of the invention, the preferably one-piece body of the massage roller consists of Expanded Polypropylene (EPP), preferably with a porosity in the range of 85 to 99%, in particular with a porosity in the range of 90 to 98%, preferably 92 to 98%, whereby a body with the ideal elastic and haptic properties is obtained.

Depending on the desired elasticity of the massage roller, the density of the foamed EPP is preferably between 1 5 g / l, in particular 20 g / l (very elastic) and 80 g / l, in particular 70 g / l (very hard).

In a preferred alternative embodiment of the invention, the preferably one-piece body of the massage roller made of engineered thermoplastic polyurethane (ETPU), which is predestined in terms of its strength, its change load resistance and its elastic properties for a hard professional use. Its porosity is preferably in a range of 75 to 95%, preferably 80 to 95%, especially 80 to 90%. In this patent application are%% information volume% information referred to. The hardness of a main body forming the massage roller preferably increases at least toward the front side having the indentation. In this way it is ensured that the roll is not deformed due to the indentation during its use. On the other hand, it is ensured that the indentation is not deformed even when using the massage roller, what the interaction with another corresponding massage element, such as a massage ball, even when used with comparatively heavy people ensures.

Preferably, the massage roller is made of a rubbery polymer material having a corresponding reversible elasticity that allows for a slight yielding when interacting with body parts, but without being deformed more.

For example, a preferred polymeric material is a preferably foamed thermoplastic which is skin neutral, odorless, water insoluble, which is also easy to clean and easy to sterilize. Furthermore, this material is preferably environmentally friendly and energy-saving to manufacture, recyclable, free of propellant gases and other chemical blowing agents. Preferably, the massage roller has a length between 1 50 and 400 mm and has a diameter between 50 and 200 mm. Such a size is easy to use for fitness, sports and physical therapy.

Preferably, the massage element consists of the same material as the massage roller, whereby the haptic properties of the massage element and the massage roller are the same.

Preferably, the massage element is formed as a one-piece polymer body and thus easy and economical to produce.

Preferably, the lateral surface of the massage roller is rubber-elastic. In this way, their use is body friendly and pleasant.

The invention equally relates to a massage set, which consists of at least one massage roller of the type described above, as well as a massage element with at least one complementary to the indentation of the massage roller part. The massage element is in particular a massage ball whose radius corresponds to the radius of the then spherical indentation of the massage roller. That way that can Massage element combined with the massage roller, resulting in a variety of other applications. At least further, the storage of such a massage set is simplified due to the spatial meshing. If the massage element is a cone, the indentation of the massage roller is naturally cone-shaped. Possible further forms for massage elements are, for example, hemispheres, pyramids, and cylinders which carry on at least one end face a projection complementary to the indentation of the massage roller.

In an advantageous embodiment of the invention, at least the surface of the massage roller at least in the region of its recess and at least the complementary part of the massage element has a surface containing a ferromagnetic material. Either the entire body of the massage roller and the massage element can contain a plastic-bonded ferromagnetic material or a plastic magnet or merely the surfaces of the two components in the region of their interaction. Preferably, therefore, only the surface of the massage roller in the region of its recess has a ferromagnetic material such as soft iron, ferrite, neodymium, samarium cobalt or NdFeB. In this way, there is a magnetic attraction between the massage element and the massage roller, so that the two components adhere to each other when they are brought into contact.

Preferably, the transitions are rounded from the end of the massage roller into the indentation present therein, which entails a more ergonomic shape and results in that no angular edges are formed on the massage roller, which could lead to pressure points in use.

Instead of a magnetic attraction layer, mechanically acting releasable connection elements, such as e.g. Velcro connections are used.

Preferably, the massage element in the radial direction of the massage roller has a diameter between 50 and 200 mm. Preferably, the width of the recess is between 10 and 20% of the axial length of the massage roller. The depth of the recess is preferably between 5 and 15% of the roll diameter. These dimensions of the recess result in conventional roller diameters, as mentioned above, to an improved treatment of fascia in the spine area and in the area of bones, such as arm and leg bones.

The different embodiments of the invention described above can be combined with one another in any desired manner. The massage set may comprise only a massage roller and a massage element, in particular massage ball, or also several of the components, e.g. a massage roller and two Massgeelemente.

Of course, the ferromagnetic particles can also be arranged in the lateral surface of the massage roller, in which case a magnetotherapeutic treatment of body parts with the massage roller is also possible

Brief Description of the Drawings The invention will now be described by way of example with reference to the schematic drawing. In this show

2 is a vertical longitudinal section through a massage roller with only a front-side recess and a central circulation groove,

Fig. 3 shows a cross section through a massage ball with a plastic-bonded soft metal coating for cooperation with the indentation of

Massage roller of Fig. 2, and Fig. 4 is a vertical longitudinal section through another embodiment of a Massagerol le with only a frontal indentation and a central recess.

Ways to carry out the invention

Fig. 1 shows a first embodiment of a Massagerol le 10, which consists of a one-piece rubber-elastic polymer body 1 1 with a porosity of 10 vol .-%. The Massagerol le 10 has a lateral surface 1 2 and two opposite end faces 14, 1 6, in each of which a recess 1 8, 20 is arranged, ie, each of which can cooperate, for example, with the outer surface of the massage ball shown in Fig. 3. In this way, the massage roller can be used together with one or two massage balls. Prinzipiel l can be used in the invention instead of a spherical indentation, a conical indentation, in which Fal l the associated massage element then must have a corresponding conical projection.

Fig. 2 shows another embodiment of a Massagerol le 30. The massage roller has a lateral surface 32 which has a central circumferential groove or recess 34 in the axial direction X. In practice, the transition from the groove or recess 34 into the lateral surface 14 will be rounded, which is more user-friendly. The massage roller 30 has a first planar end face 36 and a second end face 38, which has a spherical indentation 40. The massager oil le 30 with the one-sided spherical indentation 40 consists of a one-piece polymer material, in particular thermoplastic. In the region of its indentation 40, the massager oil le 30 is provided with a surface layer 42 which contains a plastic-bonded ferromagnetic material, such as, for example, soft iron particles, NdFeB, ferrite, neodymium or samarium cobalt. The indentation 40 with the magnetic surface layer 42 is thus designed to cooperate with a massage ball 50 shown in FIG. 3, whose wheel corresponds to the radius of the recess 40 of the massage roller 30 of FIG. 2 and the indentations 18, 20 of FIG , "

The massage ball 50 shown in FIG. 3 consists of a one-piece polymer body 52, preferably of the same material as the massage roller 10, 30. The surface layer 54 of the massage ball 50 preferably has polymer-bound ferromagnetic particles which magnetically adhere to the surface layer 42 in the area the indentation 40 of the massage roller 30 cooperate. In this way, the massage ball 50 adheres to the massage roller 30 when they are brought into contact with each other, which facilitates a combined use of these two massage components.

The massage element need not be formed as a solid ball, as shown in Fig. 3, but may also be formed as a hemisphere or as a different shaped element with a ball segment projection. The massage element can also be designed as a further cylindrical extension massage roller with an end-side ball segment projection, which can interact with the massage roller of FIG. 1 or 2, thereby creating a longer massage roller.

In principle, the massage element can also be designed as a cone when the indentations 18, 20, 40 of the massage rollers from FIGS. 1 and 2 are designed as conical indentations.

4 shows a massage roller 60 with a lateral surface 62 and a first and second end face 64, 66. While the first end face 64 is planar, a spherical indentation 68 is formed in the second end face 66. The massage roller is preferably made in one piece from EPP, preferably with a density of between 15 g / l, in particular 20 g / l and 100 g / l, in particular 70 g / l. Such a one-piece roller is easy to produce in the desired elasticity and is resistant to contamination and has a long life.

The lateral surface has axially in the middle of the roller 60, a circumferential recess 70 whose width is preferably 10 to 20% of the length of the roller 60, and whose depth is preferably between 5 and 15% of the roller diameter. The recess 70 merges with round shoulders 72 in the lateral surface and has on both sides of its center two flanks 74, which serve for better contact with the spine or with bone in the context of a fascia treatment. The transition formed by the rounded shoulders 72 preferably has an axial length u of at least one fifth and at most half of the axial length l of the depression or groove. The length u of the transition 72 can be easily determined because it is limited by the beginning of the curvature from the cylindrical surface and the change in the direction of curvature (sign change of the second derivative).

The invention is not limited to the illustrated embodiments, but may be varied within the scope of the appended claims.
