Description: The invention relates to a soles massaging device with a shoe sole part in which massage parts which can be moved up and down during operation are arranged, to the drive of which an eccentric device with an electric motor is provided.

Four different types of skin mechanoreceptors are known, the Merkel, Meissner, Ruffini and Vater Pacini receptors. By mechanical "vibration" The soles of the foot with tactile (<10 Hz) stimuli are mainly the Merkel and Ruffini receptors, with vibrotak-tilen (10-50 Hz) stimuli especially the Meissner receptors as well as with vibratilen (50-300 Hz) stimuli Father Pacini receptors aroused. For larger vibration amplitudes (> 1 mm), the proprioceptors are also excited over the entire frequency range up to about 300 Hz. The mechanoreceptor ("epicritic input") signals are routed via afferent (brain leading) neural pathways to the brain stem, cerebellum and sensorimotor cortex, which is the top processing level of the epicritic input. In mechanical solute vibration simulations in functional magnetic resonance imaging (fMRI), which can image active brain centers, it has been shown that the proprioceptive and epicritic input generated by the vibration is cortical and cerebral in the brain subcortical (brain stem and cerebellum) centers is processed. The results of these tests leave no doubt that the vibration on the sole of the foot includes all the fundamental centers of the postural system, such as primary motor, premotor, supplementary motor, proprioceptive, epicritic and vestibular centers of the cerebral cortex, subcortical centers of the basal ganglia and thalamus, and centers of the cerebellum , can excite.

In addition to the centers of the postural system, among the active brain centers with foot vibration in the fMRI, fundamental centers for human alertness and attention could be identified, demonstrating that foot vibration not only activates the brain centers for human upright posture and gait but at the same time centers for the control of alertness and attention are stimulated by a strong proprioceptive and epicritic input. Mechanical vibration on the sole of the foot can therefore be a strong stimulus or a strong stimulation for the brain centers of the postural system as well as the wakefulness and attention system of humans.

In the studies discussed above, simple massage rods were used to provide a mechanical &quot; vibration &quot; on the soles of volunteers. It would be desirable here to have a device with which a simple control just at the sensitive parts of the sole of the foot, a corresponding vibration massage can be brought about so as to stimulate the postural system and the alertness and attention. According to the latest scientific findings with vibration on the sole of the foot, the vibrating massage can be expected to provide improved motor performance and improved performance of the entire human balance and coordination system. The facility should therefore be able to be used as an accompanying training for athletes or in neurological diseases with damage to the postural system, such as in trauma, stroke or Parkinson's patients. Even in degene-rative developments of the postural system by non-use, such as the Bedrest syndrome or space sickness, the massager should be used as a prophylaxis of system degeneration, by simulating the brain so to speak, a proprioceptive and epicritic input. In addition, neurorehabilitation can benefit above all by promoting the level of alertness and attentiveness in severely and severely brain-damaged patients, since each therapy can only be of therapeutic benefit at a certain alertness level or above a certain level of attention-getting services. In patients with a spinal column syndrome, it is essential to continue to stimulate the remaining spinal cord, and in turn, vibration is a key stimulus that could ideally be achieved with a vibrating shoe. JP 2002-325819 A discloses a shoe with an arrangement of rams which are driven by a drive plate, which in turn reciprocates from a motor is driven. On the drive plate sit cams with an oblique upper side against which the plunger with their lower ends, so that they are when moving the drive plate back and forth - all at the same time - moved up and down. However, this known shoe is not very efficient and poorly suited for the stimulus or stimulation effect mentioned, apart from its mechanically unfavorable construction, in which return elements are required for moving back the plungers moving upwards with the plate and the cams. For the ram own plates are further arranged with guide openings in the shoe, below which the drive plate is located.

In US 4,802,463 A described in a shoe sole vibration massage unit is described, wherein a vibration motor via an elastic plate oscillating up and down movable tubular body drives. The tubular body are connected via rivets to the plate and embedded in an upper cushion part of the shoe sole. The vibration motor is of the eccentric type so as to generate the vibration movements.

GB 2 378 888 A discloses a vibrator inserted in a recess of a shoe sole that generates a vibration in the toe ball region of the foot. Separate massage parts are not provided here.

In GB 2 310 785 A, a massaging device extending over the length of the sole is described with a shaft driven by a motor and eccentrically mounted cylindrical massage parts on the shaft. These massage parts 20 thus perform a circular movement in order to achieve a massage effect.

Another type of foot massager that is independent of a shoe is described in US 6,285,144 B1. In this case, a massage part is moved horizontally back and forth, and for this massage part an eccentric drive with a motor, with an eccentric or a crank and provided with guides. The intentions and the construction are thus obviously a different type of foot massager.

Also in GB 2 311 4 65 A, such a shoe-independent, stationary massaging device, in particular for both feet, described, being driven by a motor via an eccentric pin in a slot of a disc, a plate up and down; this plate in turn drives a plate over springs in order to lift massage sticks. With the help of another motor, the massage pins associated drive pin can be adjusted laterally to certain massage pins not or yet - when aligned with the pins - drive.

It is an object of the invention to provide a soles massager as mentioned at the outset, with the structurally simple way a highly effective and targeted stimulation of plantar areas to achieve the above-mentioned (sport) medi-zinian and further, for the Well-being beneficial effects is made possible, moreover, the structure of the device should be as robust and easy to maintain. Furthermore, various effects can be brought about by appropriate control.

To solve this problem, the invention provides a soles massaging device as defined in claim 1. Advantageous embodiments and further developments are specified in the dependent claims.

In the present embodiment of the soles massaging device is a module-like eccentric assembly which has an eccentric or crankshaft driven by the electric motor to the massage parts piston-like up and down, wherein the massage parts in a TDC (top dead center) position protrude beyond the upper surface of the upper sole of the shoe, but in its UT (lower dead center) position, it is maximally in one plane with the upper side of the sole of the shoe. The eccentric assembly is elongate, wherein at one end of the electric motor is arranged, from which the eccentric shaft extends away. The eccentric assembly may have its own housing in which the eccentric shaft extending from the 2/20

Motor away extends, is rotatably mounted. Such an eccentric assembly is used with its longitudinal extent generally transverse to the longitudinal direction of the shoe sole part in this, and it may, for. Have two or three piston-like massage parts to massage or stimulate the sole of a subject by pressing the massage parts in the sole of the foot with the given depending on the eccentricity of the eccentric stroke and the desired frequency. The eccentric assembly can be used as such in the recess in the shoe sole part or taken out of this and exchanged, for example, e.g. if stronger or weaker strokes are desired. In this respect, the eccentric assembly preferably forms a built-in module for insertion into a preferably laterally opening recess in the shoe sole part. Via the lateral opening it is possible to finely adjust the built-in module when inserted. When the piston-like massage parts are connected via connecting rods with the crankshaft-like eccentric shaft, they are forcibly moved via these connecting rods from the top dead center position to the bottom dead center position, i. no separate return means such as springs or the like are required, such as in the case where a mere eccentric surface on the eccentric shaft drives the massage parts upward, but the return movement of the massage parts must be effected in other ways. For the latter, said return springs could be provided, but it would also be conceivable to apply sufficient pressure to the massage parts with the sole of the foot so that they are pressed downwards by the sole of the foot. Such an embodiment would also be conceivable, but the embodiment with the connecting rod connection is preferred.

The shoe sole part may be incorporated into a shoe sole of a shoe, e.g. designed in the manner of a sandal, be integrated so as to better attach the massager to a foot can. However, it is less thought of walking with such a shoe, rather, the massager is preferably operated in the resting state of the subject, even if in principle a standing or slow walking is possible. In this respect, it is also unproblematic if - as is preferred for reasons of space - the electric motor of the eccentric assembly protrudes on the side of the shoe sole part outside. Theoretically, it is also conceivable here to provide a simple plug connection between the motor output shaft and the eccentric shaft and to connect the motor housing to the housing of the eccentric shaft via a plug connection, so that the motor can be easily removed from the eccentric shaft part of the module, if desired. Preferably, however, the eccentric shaft housing and the motor are fixed together, e.g. connected by screws.

In order to adjust the massaging device with respect to the location of the stimulation to the respective sole of the foot, with regard to different foot sizes, it is preferred if the eccentric unit is adjustably received in the recess. The adjustment is possible in particular in the longitudinal direction of the sole of the foot or of the shoe sole part, for which purpose a correspondingly wide recess is provided for receiving the eccentric unit. In a corresponding manner, the openings provided on the upper side of the shoe sole part for the massage parts must also be sufficiently large, with a corresponding width in the longitudinal direction of the shoe sole part, in order to be able to effect the desired adjustment. Nonetheless, in order to firmly attach the eccentric assembly in the shoe sole part, a clamping mechanism is expediently provided, which fixes the eccentric assembly in the recess in the set position. This clamping mechanism can be realized for example with a clamping plate and a clamping screw, it is particularly advantageous if the clamping mechanism has an outer eccentric lever (clamping lever), which is connected by means of a projecting on the underside of the shoe sole part bolt with the actual eccentric assembly. With such an eccentric lever can be solved without the aid of a tool quickly and easily the clamping of the eccentric assembly or brought about, the eccentric or clamping lever can act, for example, in the manner of a quick release lever in a bicycle saddle, etc. substantially.

[0016] For the acoustic decoupling of the eccentric assembly from the shoe sole part, in particular

On the underside thereof, as well as to reduce the transmission of vibrations, it is further favorable if at least one damping layer is provided on the underside of the eccentric assembly. The damping layer may be formed, for example, by an elastomeric damping plate.

Depending on the objective, the eccentric unit can be equipped with several, in particular two or three, massage parts, whereby also the point of attachment - whether in the narrower heel area or in the wider toe bale area of the shoe sole part - can play a role. In a simple embodiment, an eccentric assembly is mounted in the shoe sole portion in the toe ball area. This eccentric assembly may for example have three piston-like massage parts.

Instead or preferably additionally, an eccentric unit can also be provided in the heel area, wherein this eccentric unit preferably has two piston-like massage parts. In the case of just one eccentric unit, in particular in the toe ball area, a particularly favorable application of the massager for wellness purposes results. In the case of two eccentric assemblies are provided, one in the toe ball area and the other in the heel area, there is a particular suitability for rehabilitation therapy. In this case, it is also expedient to provide each Exzenterbaueinheit with its own, independent of the other electric motor electric motor, which under certain circumstances, the two electric motors can rotate at different speeds. Preferably, however, an equally fast movement of the massage parts is desired, but in this case with a 180 "phase shift between the massage parts in the heel area and those in the toe bale area; this means that when the piston-like massage parts in the toe bale area are in the top dead center position, the massage parts in the heel area are in the bottom dead center position and vice versa. This phase shift can give the brain a walking motion, i. Rolling movement of the foot, be simulated, which may be particularly favorable for certain rehabilitation therapies.

To control the eccentric units, a control unit connected to the or each electric motor can be arranged in the shoe sole part, and this control unit controls in particular the electric motors of the two eccentric units with the mentioned 180 ° phase shift. Furthermore, it is possible with the control unit, the rotational speed of the electric motor or the electric motors and thus the stroke frequency, i. to control the frequency of the up and down movement of the piston-like massage parts. The stroke frequency can be adjustable, for example, between 1 Hz and about 100 Hz (or 300 Hz). The low frequency range of about 1 Hz to about 15 Hz is mainly used for rehabilitation applications, whereas medium and higher frequency ranges are particularly suitable for wellness and sports medical applications. The penetration depth of the massage parts into the sole of the foot (skin), that is to say the stroke of the massage part, can amount to approximately 1.5 mm, for example.

For power supply, an external power source, such as an accumulator (in the low voltage range) may be provided. But it is also conceivable to install such a power source (battery, battery) in the shoe, especially when it comes to space-saving lithium-ion or lithium-polymer batteries.

The shoe sole part is preferably provided with a top-side, deformable protective film, which serves to protect the drive unit against ingress of contaminants or liquids from the environment and to simplify the cleaning of the device.

Overall, therefore, a very efficient, nonetheless robust and easy-to-install massaging device in the manner of a massage shoe with a massage sole is provided by the invention, with the various stimuli of the sole of the foot allows in particular in the field of medicine or rehabilitation and thus advantageous stimulation effects can be brought about. On the other hand, the massager can also be used well for sports-medical purposes and for wellness purposes.

The invention will be described below with reference to particularly preferred Ausführungsbeii- play 4/20, to which, however, it should not be limited, and further explained with reference to the drawings. In detail in the drawing: FIG. 1 is a diagrammatic view of a foot sole massaging device according to the invention in the form of a sandal, in a view obliquely from above at the top; Fig. 2 of this massager in a corresponding view obliquely from the front front, but with the protective film removed to show the piston-like massage parts of the two Exzen ter assemblies; Fig. 3 is a perspective view of the arrangement of the two eccentric assemblies in the shoe sole part, wherein an upper part of the shoe sole part has been omitted; Figures 4 and 5 are sectional views through the eccentric assemblies themselves, namely one for the toe bale region (Figure 4) and one for the heel region (Figure 5); 6A and 6B are cross-sectional views of the shoe sole portion in the area of the toe bale, with a longitudinal sectional view of the eccentric assembly provided therein, wherein the piston-like massage parts in the illustration of Fig. 6A in the UT position and in the illustration of FIG 6B are in the TDC position; FIG. 7 a longitudinal section through the shoe sole part with the eccentric assemblies; FIG. Fig. 8 is a bottom view of the massage apparatus shoe, illustrating Exzen ter clamping levers for fixing the eccentric assemblies; 9 shows a partial cross section in the region of an eccentric assembly to illustrate the clamping mechanism with the eccentric clamping lever in the closed position. and FIGS. 10, 11 and 12 show similar cross-sectional views, but with the tensioning lever in a view, in FIG. 10 the closed position of the eccentric tensioning lever, in FIG. 11 an intermediate position when the eccentric tensioning lever is opened, and [0033] FIG. in Fig. 12, the open position of the eccentric clamping lever is shown.

In Fig. 1, a massage device 1 is shown in the form of a massage shoe, which is formed like a sandal with belt 2 and a shoe sole part 3. The shoe sole part 3 carries on its upper side a protective film 4, which is removed in Fig. 2, to illustrate upper side openings 5, 6 in the shoe sole part 3 and therein, movable up and down piston-like massage parts 7. These massage parts 7 belong to two eccentric assemblies 8, 9, wherein the front eccentric assembly 8, which is equipped with three massage parts 7, arranged in the toe ball area and the rear eccentric unit 9, which is equipped with two massage parts 7, in the heel area is. As further shown in Figures 1 and 2, are parts of the eccentric assemblies 8, 9 laterally from the shoe sole part 3 before; 1 and 2, also Fig. 3. Between these electric motors 10, 11 there is a connection part 12 for the power supply, wherein behind this connection part 12, already in the Inside the shoe sole part 3, a control unit 13 is provided, s. In particular, Fig. 3. Further, a controller knob 13A is provided on the connection part 12 and on the control unit 13 outside, which serves to adjust the speed. From the electronic control unit 13, which also worries the power supply of the electric motors 10,11, lead corresponding tracks to the electric motors 10 and 11. These are preferably multi-core flexible traces 14, 15, the particular shown in FIG. 3 curved Course can have.

The eccentric assemblies 8, 9 are with lower projections 16 and 17 on the lower housing part 18 and 19 in guide recesses 20 and 21 in corresponding raised parts in the interior of the shoe sole part 3, specifically of its lower half 3A, received, so as to adjust the eccentric assemblies 8 and 9 transversely to its longitudinal direction, thus substantially in the longitudinal direction of the shoe sole part 3 and the massage shoe, guided. In order to enable this adjustment also in the area of the upper part of the sole of the shoe sole, the openings 5, 6 provided there for the massage parts 7 are elongated in the longitudinal direction, as is shown in FIG. 2 (FIG. 2) Fig. 2 can be seen. This allows adaptation of the massage shoe or massaging device 1 to shoe sizes of 38 to 45. The fixation of the respective eccentric assembly 8 or 9 by clamping to the raised portions 22, 23 in the lower sole portion 3A takes place in each case by a below with reference to FIGS. 8 to 12 in more detail to be explained clamping mechanism 24 and 25 with an eccentric tensioning lever 26th or 27.

From Fig. 4 and Fig. 5, the two eccentric assemblies 8 and 9 in an axial longitudinal section (ie in a section according to a sectional plane approximately transversely to the longitudinal direction of the shoe sole part 3) are shown; It can be seen that each eccentric assembly 8 and 9 has an eccentric shaft or crankshaft 28 and 29, which is coupled via a clutch 30 and 31 respectively to the respective motor 10 and 11 (or its unspecified output shaft) , Each eccentric shaft 28 and 29 is rotatably mounted in bearings 32 in the region of their ends, said bearings 32 between the lower housing parts 18 and 19 and upper housing parts 33 and 34 are held. Each eccentric shaft 28 and 29 is provided in the region of the associated massage parts 7 with eccentric portions 35 which are round in cross-section, but with a center axis outside the longitudinal axis of the eccentric shaft 28 and 29. In these eccentric 35 are connecting rod bearings 36 on the eccentric shaft 28 and 29 mounted to store connecting rods 37, which in turn are connected via piston pin 38 with the piston-like massage parts 7. The piston-like massage parts 7 are further slidably guided in cylinder liners 39 in the upper housing part 33 and 34, respectively.

4 and 5, the abovementioned projections 16 and 17 can be seen on the underside of the lower housing part 18 and 19, which at the same time each for receiving a bolt 40 (see Fig. 6A and 6B and in particular Fig. 9) of a bearing part 41 (FIG. 9) of the respective eccentric clamping lever 26. For these bolts 40 corresponding bores 42 are provided in the respective projection 16 and 17, respectively, which can be provided, for example, with an internal thread for screwing in the bolt 40, which has a corresponding external thread; Alternatively, a fixed interference fit for the bolt 40 may be provided in the bore 42.

Further, from Fig. 4 and 5 at the bottom of the lower housing part 18,19 damping layers 43 in the form of elastomeric damping plates can be seen, the installation of the respective eccentric assembly 8 and 9 in the shoe sole part 3 underside a vibration decoupling between the eccentric assembly 8 and 9 and the lower half 3A of the shoe sole part 3 accomplish, see also the illustration in Figs. 6A and 6B. Incidentally, the bearings of the respective eccentric clamping lever, in this case, for example, are also shown in FIGS. 6A, 6B. of the clamping lever 26, in the bearing part 41 by means of a bearing axis 44 can be seen.

From Fig. 4, 5, 6A and 6B is then still recognizable that the respective eccentric shaft 28 and 29 is provided in the sections between the connecting rod bearings 36 with eccentric counterbalancing projections 45, so as to rotate the eccentric shafts 28 and 29 despite the eccentric 35 to ensure uniformity and to prevent any inclinations to vibrations.

From Fig. 7, the shoe sole part 3 with the two eccentric assemblies 8, 9 can be seen in a longitudinal section, which can also be seen that the two eccentric assemblies 8, 9 with the direction of the stroke movement of their piston-like massage parts obliquely to Vertical, with horizontally held shoe sole part 3, are arranged so as to achieve the shape of the sole of the foot to achieve the ideal massage strokes. 7, the two flexible interconnects 14, 15 and the control unit 13 (including power supply part), from which the two interconnects 14, 15 lead away, and also the two eccentric shafts 28 and 29 between the housing parts (eg 18 and 33 ) of the assemblies 8 and 9 (here in particular the assembly 8). Finally, due to the cutting guide in Fig. 7 especially for the rear eccentric tensioning lever 27, arranged for the heel area eccentric assembly 9, its storage on the bearing part 41 on the bearing axis 44 clearly visible. The 6/20 &amp; s! Ia he AT 506 689 B1 2009-11-15

Storage of the other eccentric clamping lever 26, for the front eccentric assembly 8, is completely identical, even if this is not immediately apparent due to the cutting guide in Fig. 7. A corresponding sectional view, on an enlarged scale, however, is shown in Fig. 9, where there also the eccentric portion 35 and the connecting rod bearing 36 on the eccentric shaft 28 for one of the massage parts 7 (not visible) can be seen.

Moreover, it can be seen from Fig. 9 that the two housing parts 18, 33 may be connected to each other for example by means of screws 46 for the eccentric shaft. Similarly, the two halves 3A, 3B of the shoe sole part 3 with each other via screws 47, s. Fig. 8, are connected.

Furthermore, connecting bolts 48 can be used to connect the respective motor 10 or 11 with the respective housing parts 18, 33 and 19, 34 of the eccentric assemblies 8 and 9, respectively. Instead, however, a simple mating or snap connection of the motors 10,11 are provided with the eccentric shaft housings so as to allow rapid assembly or disassembly of the motors 10 and 11 respectively.

From Figs. 7 to 12 it can be seen that the clamping mechanism 24 or 25 in a respective recess, e.g. 49, is housed in the lower half 3A of the shoe sole part 3. Thereby, the eccentric lever 26 (or 27) is received within the recess 49 in the closed position shown in Figs. 7, 8, 9 and 10, i. he does not stand out from this underside of the shoe sole part 3.

In this closed position, see Fig. 9 and 10 in particular, which corresponds to an over-center position of the eccentric 50 of the eccentric lever 26, pulls this lever which rests with the eccentric 50 on the underside of the lower half 3A of the shoe sole part 3, the eccentric shafts Housing (eg 18-33 in the case of the eccentric assembly 8) down against the lower sole half 3A and thus clamps the assembly 8 against this lower half 3A.

When the eccentric lever 26 is moved from this closed position shown in FIG. 9 and 10 via the intermediate position shown in FIG. 11, in which the strongest clamping effect is due to the eccentric training, in the open position shown in FIG. 12, the clamping action is released , wherein the eccentric lever 26 as shown in FIG. 12 is no longer in this position with its eccentric 50 on the underside of the lower sole part half 3A abuts. In this position, the eccentric assembly 8 (or 9) can be adjusted for adjustment to the foot size. In this position, the damping plates 43 are relaxed.

For an expansion of the eccentric assembly 8 or 9, it is necessary to loosen the screws 47 and remove the upper half 3B of the shoe sole part 3, after which with the eccentric lever 26 and 27, the respective pin 40 is removed, e.g. turned out, will. Thereafter, the eccentric assembly 8 and 9 are separated from the lower half 3A of the shoe sole part 3. When installing reverse the procedure.

The control unit 13 includes a speed control part for the electric motors 10,11. These motors 10, 11 may be stepping motors whose speed can be controlled accurately. It is further possible, the two motors 10, 11 to be arranged and drive, that the associated eccentric shafts 28, 29 are rotated exactly opposite in phase, i. Whenever the associated massage parts 7 are located on the one eccentric shaft 28 in the TDC position, the massage parts 7 are present on the other eccentric shaft 29 in the UT position. This 180 "phase shift when driving the two eccentric shafts 28, 29 can be exactly maintained with the motors 10, 11, which are independent of each other, and where appropriate position encoders in the motors 10, 11 can also feed back the respective position of the rotor into the control unit 13, to ensure a very precise regulation. Furthermore, with the control unit 13, the rotational speed of the motors and thus the stroke frequency of the massage parts 7 can be adjusted, with stroke frequencies from 1 Hz to about 100 Hz can be given as an example. In the case of rehabilitation therapy, lower frequencies, e.g. 1 Hz to 15 Hz, whereas the higher stroke frequencies may be important for wellness applications and sports medicine. The 7/20
