Description

TECHNICAL AREA

The present invention relates to a massage device for massaging a limb, in particular for self-application.

BACKGROUND OF THE INVENTION

For massaging limbs, various massaging devices are used in sports medicine, orthopedic, physiotherapeutic or training applications, which should also be suitable in particular for the self-use of a user. In recent years, massaging devices for self-application as a supplement to conventional muscle training and to relieve tension or hardening have gained in importance, especially for the increasingly popular fascia training.

In the prior art various massage devices for self-use are known.

The US6033372 A describes a non-electric hand massage device for massaging a person's hands, arms, feet and legs. The device consists of a pair of opposed rigid rollers, each of which is provided with a plurality of resilient projections extending from the surface of the Extend rollers to the outside. The rollers end in waves, which are held in rails on both sides of the rollers. A pair of elastic cords are located in the cavity that forms within the rail part and the handle part. The elastic cords end in shaft holders, which are connected to the shaft ends of the rollers. The elastic cords are placed so that a spring tension between the two roles arises, so that the user, if he inserts his hand or his foot between the rollers, receives a massage, which by the effect of the many elastic tips of the on the skin of the User's incident roll surface. A removable cover located on top of the rail allows the user to adjust the spring tension and remove and replace the rollers.

The US2017 / 0156968 A1 describes an arm therapy device for the prevention and treatment of repeated stress injuries to the elbow, forearm and wrist. The arm therapy device includes a housing that is adapted to be erected upright. The housing has an upper opening, which allows access to the housing interior. Rollers inside the housing consisting of pairs of rollers biased inwardly against each other. Biasing elements, such as resistance bands, can be used to bias each pair of rollers against each other. Cuffs can be used on the rollers to which the biasing elements are connected. With the present invention, one can treat a limb such as an arm without having to support the housing with another hand or another person. When the extremity through the housing The rollers exert pressure on the extremity, which is helpful in treating or preventing repeated stress injuries.

PRESENTATION OF THE INVENTION

In the massage devices, it is desirable to achieve a variation in the force exerted during the massage, depending on the body or limb being treated and the nature of the tensions or indurations. Especially with massage devices for self-application, a simple and rapid variation of the applied force by the user himself should be made possible. The applied force by the user should be as small as possible during the massage.

It is therefore an object of the invention to at least partially improve the state of the art of massage devices for massaging limbs, in particular for self-application.

This object is solved by the features of the independent claim. Advantageous embodiments of the invention are given in the dependent claims and in the present description and the figures.

The invention relates to a massaging device for massaging a limb, comprising a peripheral frame with a central recess and two cylindrical rolling elements which each extend from one side of the frame via the recess to an opposite side of the frame and are each rotatably mounted about a longitudinal axis. The massage device is characterized in that the rolling elements are arranged in a massage configuration with respect to the frame translationally stationary on the frame so that the longitudinal axes of the rolling elements for insertion of the limb enclose an acute angle.

The invention provides an easy-to-use and effective self-administering massage device which is particularly useful for fascia training of limbs, e.g. Arms or legs, is suitable. The encircling frame provides a stable supporting structure which allows the application of great forces and / or torques during the massage while ensuring the stability of the massage device. In the central recess, an insertion area can be defined, which is bounded by the cylindrical rolling elements and sections of the frame and in which a limb can be inserted. In particular, a limb mass between the rotatable about a respective longitudinal axis rolling elements are reciprocated so that a massage of imported between the rolling elements limb is performed.

As a result of the arrangement of the cylindrical rolling elements on the frame translationally fixed relative to the frame in a massage configuration, the rolling elements can exert sufficient force or pressure on the limb during the passage of the limb between the rolling elements so that tension and / or hardening can be released. In comparison to spring-loaded rollers from the prior art, the translationally fixed arrangement allows the exercise of higher forces on the limb with the same or similar force, so that the effectiveness of Massage is increased. Furthermore, the translationally fixed arrangement of the rolling elements and the surrounding frame offer the advantage that in the massage no moving parts of the massage device must be held together manually to exert a certain force on the limb.

The acute angle subtended by the longitudinal axes of the rolling elements results in a variation of the distance between the rolling elements along the longitudinal axes of the rolling elements and thus permits a variation of the applied force on the limb by displacing the position of the limb along the longitudinal axis of the rolling elements. For a higher applied force during the massage, the limb may be displaced relative to the rolling elements in a direction in which the distance between the rolling elements decreases. For a gentler massage with lower applied force, the limb may be displaced relative to the rolling elements in a direction in which the distance between the rolling elements increases. In addition, an optimal position for the limb between the rolling elements can be found by the acute angle or the varying distance between the rolling elements for different limbs and / or for different users, in which an optimal force can be exerted on the limb during the massage.

In general, the cylindrical rolling elements are dimensioned such that the length of the cylinder defined by the lateral surface of a rolling element is at least as large as twice the diameter of the cylinder.

In a preferred embodiment, the frame has a fastening device which is designed such that at least one of the rolling elements for setting different massage configurations along one side of the frame in at least two, preferably three, more preferably four, with respect to the frame translationally fixed positions solvable in the fastening device is engageable.

This embodiment has the advantage that different angles between the longitudinal axes of the rolling elements and different massage configurations can be set by the different positions of the rolling elements along one side of the frame. Thus, the variability of exercisable during the massage forces can be increased. As a rule, the rolling elements each engage the fastening device at one end, so that the position of one end of a rolling element along one side of the frame can be changed by releasing and engaging the rolling element from and into the fastening device. In this case, one end or both ends of one of the rolling elements or one end or both ends of both rolling elements in different positions along one side of the frame releasably engage in the fastening device.

In one embodiment, at least one rolling element has a pin on at least one end and the fastening device has at least one recess into which the pin can engage in at least two, preferably three, more preferably four, positions, wherein the pin is preferably designed as a push button subjected to spring force ,

The fastening device preferably has a protruding from the plane of the frame, preferably plate-shaped projection in which the recesses are formed. Due to the spring-loaded push button, the rolling element can engage in a simple manner in the fastening device and be released again. Preferably, both rolling elements at both ends of a pin.

In one embodiment, at least one of the rolling elements, preferably via pins at both ends of the rolling elements, releasably engageable in the fastening device, that in the respective massage configurations with respect to the frame translationally fixed positions of the rolling element along the sides of the frame to which the rolling elements attached are independently adjustable.

As a result, the adjustability of different massage configuration can be further improved and simplified. Preferably, the positions of the two ends of both rolling elements are independently adjustable. In particular, the orientation of the angle bisector of the acute angle can be changed, which further improves the flexibility in the application of the massage device.

In one embodiment, the position of the rolling element translationally fixed relative to the frame is in each case adjustable such that the angle between the longitudinal axes of the rolling elements in the respective massage configuration is between 3 ° and 23 °, preferably between 5 ° and 21 °, more preferably between 7 ° and 19 °.

In a preferred embodiment, the position translationally fixed relative to the frame is adjustable from both ends of the rolling element such that the rolling element is adjustable with respect to its longitudinal axis by an angle of ± Δ. Preferably, Δ is between 3 ° and 10 ° and more preferably between 5 ° and 8 °. Further, Δ is preferably selected from [5 °, 5.5 °, 6 °, 6.5 °, 7 °, 7.5 °, 8 °]. Particularly preferably, with respect to the frame translationally fixed position of both ends of the rolling element is adjustable so that the rolling element with respect to its longitudinal axis by an angle of ± Δ is adjustable, wherein the rolling element in this case preferably about a longitudinal axis to the longitudinal axis, the rolling element in the intersecting half Axis, is pivotable.

In one embodiment, the rolling elements are identical.

Due to the identical design advantageously a symmetrical force on the imported limb can be achieved. Furthermore, the identical rolling elements offer the advantage of low production costs for the massage device.

In one embodiment, the rolling elements on a rigid surface.

In general, the rolling elements are rigid, which offers the advantage of an increased exercisable force. Optionally, the rolling elements on the surface of a have elastic and / or damping layer, which eg improves the feel during the massage. The layer on the surface may, for example, comprise a rigid foam.

The surface of the rolling elements may be formed smooth to provide a continuously smooth contact surface between rolling element and limb. Alternatively or in addition, the rolling elements may at least partially have a profiled surface. The profiled surface may comprise conical and / or pyramidal elevations. In one variant, a rolling element may have a smooth surface and the second rolling element may have an at least partially profiled surface. Rolling elements with different surfaces may be advantageous if e.g. for a given side of a limb, a massage with a profiled surface is suitable for releasing certain tensions, and for an opposite side of the limb a massage with a smooth surface is suitable.

In one embodiment, the frame has on the edge side a concavity, which preferably aligns the frame transversely to a longitudinal axis of a rolling element.

The concavity can be used to support the massage device during massage, preferably on a limb that is not massaged. For example, in a massage of an arm, the massage device may be supported over the concavity on a thigh of a user.

In one embodiment, the frame has at least one handle, which preferably comprises at least one recess oriented towards the recess in the frame.

By the handle, the massage device by a user, especially during the massage, be taken safely. This is particularly advantageous for self-application. By a recess in the frame, such a handle can be made low. Advantageously, the frame has a plurality of recesses into which the fingers of a hand can engage. The frame may also have edge recesses for forming a handle.

In one embodiment, the handle is arranged on one side of the frame, which is oriented along a longitudinal axis of a rolling element.

Preferably, the massage device has two handles, which are arranged symmetrically on the frame and are each oriented along a longitudinal axis of the rolling element.

The handle is advantageously arranged along the concavity, so that the massage device during the support of the same on a limb, such as a thigh, can be securely held by the user. In particular, the recesses in the frame for forming the handle and the concavity are advantageously on opposite sides of a frame portion arranged so that a user's hand can engage in both the concavity and in the recesses.

Preferably, the frame is mirror-symmetrical with respect to an axis of symmetry, which improves the application flexibility and the stability. Particularly preferably, the rolling elements are adjustable in a massage configuration, in which the massage device is mirror-symmetrical with respect to an axis of symmetry.

In the context of the invention it is conceivable in certain embodiments that the massage device comprises more than two cylindrical rolling elements, which are formed according to the present description and define a plurality of insertion regions with acute angles between the longitudinal axes of the rolling elements.
