Definitions

• the invention relates to a roller massager, in particular also against cellulite, according to the features of the preamble of claim 1.
• a roller massager on the housing of which a roller driven by an electric motor is rotatably mounted.
• the roller has on its outer circumference protruding webs which are designed in the form of rings and inclined to the central axis of the roller and which, when the device with the rotating roller is guided over the skin, cause the upper layers of fabric to shift in the longitudinal direction of the surface of the skin cause what leads to massage and relaxation of the tissue, thus also to the reduction of cellulite, in people.
• the roller massager is in operation, the skin is treated in such a way that it is first moved in one direction and then in the opposite direction per revolution of the roller over the entire surface.
• Another roller massager is known from FR-A-2 682 594, in which the skin is massaged between two rollers rotating at different speeds when the device is constantly guided over the surface of the skin. Due to the rollers rotating at different speeds, the skin is drawn from the one roller into the free space formed between the rollers faster than it can be removed from the annular space by the slowly rotating roller. This leads to constant deformation and thus a massage of the skin.
• the object of the invention is now to provide a roller massager, by means of which the most massaging possible effect is exerted on the skin with the simplest possible means, without the device having to be constantly moved back and forth by hand.
• the object is achieved by a device with the characterizing features of patent claim 1.
• the skin is pressed at least once during each rotation of the roller during operation of the roller massager and then pulled apart again.
• an effective massage of the skin is achieved.
• the tensile pressure exerted on the skin by the webs is achieved by the webs which are arranged inclined to one another on the roller. A change in the direction of rotation of the roller is not necessary.
• the surface of the webs should of course be made correspondingly rough, i.e. the more the coefficient of friction between the webs and the skin is, the higher the tensile compressive stress is with the same force applied to the roller on the surface.
• the inclined arrangement of the webs with respect to one another means that the distance between two adjacent webs when the roller massager rolls off the skin is always different.
• the skin is stretched and compressed between the webs, since when the roller is put on, the individual skin sections between the webs are, to a certain extent, clamped, that is, held when the roller massager is passed over the skin with a certain contact pressure becomes.
• roller massager With the roller massager according to the invention with a rotating roller with a shaped surface, an intensive massage movement is achieved, combined with pressure, relaxation, flexing and kneading of the tissue. In addition to the very effective massage effect, this also counteracts cellulite, which means that, among other things, the microcirculation is increased and the breakdown of metabolic waste is promoted, which leads to the well-being of the person.
• the webs are designed as rings rotating on the roller, which can rotate with the roller. If the rings are connected to the roller in a rotationally fixed manner, on the one hand a massage effect in the circumferential direction and transversely to the circumferential direction of the roller is produced, the massage effect increasing with higher load of the roller on the skin; however, this is also dependent on the coefficient of friction formed on the surface of the webs.
• a roller can be manufactured particularly easily if the rings are molded onto the circumferential surface when the roller is manufactured.
• a plastic with higher surface friction values has proven itself as a material; the latter can also be influenced by the surface condition of the webs.
• the webs are slidably guided on guide rails formed on the roller.
• the webs can be held on the housing for the first time so that they do not rotate with the roller.
• the webs are arranged on the outer circumference of the roller so that their planes to the central axis of the roller form an angle g.
• the webs of rings are formed according to claim 6, which are guided on the guide rails.
• the individual rollers are divided into pipe sections according to the features of claim 7, and at the same time the guide rail is formed at least at an end face of each pipe section.
• the rings can be placed on the guide rails from the outside without having to be widened or placed in individual parts and then joined together to form a ring. It is advantageous that the individual pipe sections are pushed onto a pipe carrying them. However, the tube could be avoided if the individual tube sections were plugged onto one another and centered with one another via centering devices.
• the individual pipe sections according to the development of the invention also have the advantage that they themselves can be replaced individually, but this also applies to the rings or webs.
• the guide rail can either be designed as a groove in which the ring or web engages or also as an annular collar in which an annular groove formed on the ring engages.
• other guide rails can also be used; it is only important that the individual rings always maintain their inclination with respect to the roller and are nevertheless guided in a sliding manner on the roller. Due to the features of patent claim 8, the two ends only form the guide device or groove after the individual pipe sections have been joined, so that both parts take on not only the radial but also the axial guidance of the webs.
• the guide device is formed only on one end of the pipe section, so that the end section of the other pipe section adjoining there merely creates the lateral boundary so that the ring on the lateral surface of the groove is also axially opposite the other Pipe section is held.
• patent claim 10 further prevent contact of the peripheral surfaces of the individual pipe sections, and the webs protrude further from the circumferential surface of the pipe sections. This measure also leads to a better massage result with little effort or energy.
• the guide rails order from ring grooves in which the rings engage.
• the individual webs can also be designed as ring sections which, in order to allow them to slide on webs by the guide devices of the roller, are connected to the latter by means of an annular dovetail guide, for example.
• the ring section would encompass the guide device from the outside, so that when the roll rotates, it is guided by the guide device, which also rotates, in the axial as well as in the radial direction, but even completely or partially with the roll. turns wisely.
• the ring section only has to be supported in a rotationally fixed manner on the housing. Because the webs are divided into two sections, a second section in the form of an attached ring piece can be attached to the first section, namely the ring part guided in the groove, which section is then supported on the housing-side support part.
• the ring sections are held in place relative to the roller on the housing, but they must be axially displaceable in the holder in order to utilize the push-pull movement.
• the adhesive or friction value or the massage effect between the webs and the wall can be changed by the material selection and surface properties of the webs.
• Spraying or coating the surface of the webs with rubber-elastic material is extremely easy to produce.
• the roughness of the surface can, for example, be carried out directly on the rubber-elastic material.
• a buttonable rubber cap has the advantage of being easy to replace after it has worn out or if softer or hard treatment surfaces are to be used (claim 17).
• a roller massager can include several rollers with different web profiles, which, depending on the application, are inserted into the device accordingly. can be set. However, if rollers with individual roller sections are used, between which the individual webs are guided, it is sufficient to replace the webs with other webs with different profile properties, without the need to replace the individual tube sections. However, care must be taken that the guides formed on the webs are always adapted to the guide rails of the roller. Different massage results can be achieved by changing the web profile.
• An operator can increase or decrease the massage effect on the skin due to the slip clutch between the webs and the tube, depending on the contact pressure of the rings, without the rotational speed of the drive having to be changed.
• An increase in the diameter of the roller can be achieved, for example, by inserting an expanding device acting in the radial direction into the interior, which can be actuated laterally from the outside by means of a threading or tensioning device.

With this arrangement, the skin 94 is massaged easily. The higher the pressure of the hand-held roller massager 20 on the skin via the webs 86, the greater the frictional engagement between the webs 86 and the skin 94. In the massage process, kneading and flexing takes place with the formation of friction on the skin 94, which increases the blood flow to the skin, changes the muscle tone, intensifies the transport of veins and lymph, activates hormones and has a reflective effect on the internal organs and the tissues of the body cover. The smaller the angle f, the smaller the path of two webs 86 in the longitudinal direction X, but the more webs can be arranged on the roller 24 for this.
• the webs 86 are firmly connected to the roller 24, so that there is still a frictional force acting on the skin 94, which still leads to increased blood flow to the skin. If the webs 86 are rotatably mounted in the ring grooves 82, so these stop immediately as soon as the webs 86 are placed on the skin. In the embodiment shown in FIG. 5, however, the webs 86 are fixed from the outset in the interior of the housing 21 to the support part 28 in a rotationally fixed manner or abut there in the circumferential direction of the roller 24, so that a pure axial movement along the direction X takes place on the skin 94.
• the electric motor 51 could also be speed-controlled, so that, depending on the perception of an operator, the skin 94 can be subjected to higher train-push movements.
• FIG. 6 it can be seen how the webs are formed and fastened in a rotationally fixed manner in the middle part 25 of the housing 21. Radially protruding projections 102 are formed on the ends of the webs 86 and rest on the support parts 28. The webs 86 are secured against rotation in that the end 103 of the rubber-elastic layer 90 is supported on the lower edge 104 of the supporting parts 28.
