Description

Field of the invention

The invention relates to a massage device, in particular for sexual stimulation, with arranged in the housing electromechanical means for generating mechanical vibrations, with arranged in the housing electronic means for controlling the means for generating mechanical vibrations and with an energy source, which with the means for generating mechanical Vibrations and the electronic means is connected, wherein the means for generating mechanical vibrations at least one coil element and at least one arranged parallel or coaxial with the coil element and parallel to a cylinder axis of the housing slidably guided ferromagnetic core. Furthermore, the invention relates to the use of such a massage device for sexual stimulation.

Prior art and background of the invention

Massaging devices for sexual stimulation are for example from the literature US 3,991,751 and US 4,377,692 known. These are substantially in the form and shape of a male member modeled devices which have built therein means for generating mechanical vibrations. In the massage devices known in this respect, the means for generating mechanical vibrations typically have an electric motor, on whose axis a vibration element is fixed with imbalance. As a result, a vibration is generated during rotation of the electric motor, which is generally orthogonal to the longitudinal extent of the housing, since the axis of the electric motor is arranged parallel to the housing axis. In the case of known massagers oscillations of relatively high frequency and with a small stroke are generated. In addition, disturbing noises usually arise with the frequency of the vibrations. All this is disadvantageous in the application of the massager, as this is perceived as rather disturbing.

Massagers of the structure mentioned above are for example from the literature DE 29913641 U1 . DE 2310862 A and DE 19615557 A1 known. In the former reference, the means for generating mechanical vibrations are speaker elements whose loudspeaker axis is parallel or coaxial with the cylinder axis of the housing. Due to the use of loudspeakers, the vibrations generated have a relatively high frequency with minimal lift in the direction of the cylinder axis. At the subject of DE 19615557 only one front end of the housing is vibrated and not the housing as a whole. Consequently, the massage effect is rather low. The subject of the reference DE 2310862 the direction of the vibrations remains unclear.

In massagers for the above-mentioned purposes, it is generally desirable that, on the one hand, the massager itself makes a total of oscillations, on the other hand these oscillations have a relatively high amplitude, and finally that the oscillations are made in directions parallel to the housing axis of the cylindrical housing, as this greatly improves Massage effect results. In addition, it is desirable that such a massaging device is very quiet, preferably virtually silent, operable.

A massager which excellently solves the above problems in essence is known from the literature WO 2009/152813 A1 known. In the case of the massage device known to date, however, details can be improved, in particular with regard to the impact elements, which limit or dampen the movements of the core in the regions of the movement reversal. Because the springs and / or foams used or the like can on the one hand at a very high vibration amplitude of the core "penetrate" with the result that shocks and associated noise are felt, both of which is perceived as unpleasant. In addition, foam in particular as impact elements wear off over time and lose their damping effect, again with the result of increasingly noticeable blows and audible noises. Finally, energy consumption and length can be further optimized.

Technical problem of the invention

The invention is therefore based on the technical problem of specifying a massager, which performs a total of relatively high amplitude vibrations in directions parallel to the housing longitudinal axis, with low frequency, improved comfort even at high amplitudes and improved freedom from noise and improved massage effect. Furthermore, the technical problem underlying further optimize energy consumption and overall length.

Main features of the invention and preferred embodiments

To solve this technical problem, the invention teaches that the baffle elements are designed as end magnets, wherein each of the ends of the core facing ends of the end magnets have a magnetic polarity, which is the same the polarity of the respective facing ends of the core.

The magnetization direction of both the core and the end magnets is parallel, in particular coaxial with the housing (longitudinal) axis, so that the magnets at each of their ends, viewed in the direction of the housing (longitudinal) axis, each having a north and a south pole. The end magnets can be designed both as permanent magnets, as well as electromagnets.

With the invention it is achieved, on the one hand, that the massaging device performs particularly soft and in particular stroke-free reciprocating motions, because the end magnets very softly and progressively attenuate any kinetic excess energy of the core in the region of the movement reversal points. In addition, disturbing noises are reliably prevented by striking the core at the ends of the cylinder component. Furthermore, the invention allows to reduce the overall length of the cylinder component with a constant massage effect. Also, the energy consumption of the massage device is reduced with constant massage effect, because the inventively designed impact elements work virtually without loss, so particularly effective "spring back", unlike, for example, foam baffles in which a significant portion of the kinetic energy of the core in the "spring back" lost goes. Finally, end magnets used according to the invention operate virtually wear-free, so that all the above advantages are retained over the entire service life of the massager.

In detail, there are a variety of opportunities for further education.

Thus, it is expedient if the magnetic field strengths of the core and the end magnets are selected and set with the proviso that with a vertical arrangement and without the action of external magnetic external fields with additional loading of the core with the 2- to 30-fold, preferably the 4 - Up to 24 times, in particular 6- to 18-fold, its own weight between the core and final magnet still an air gap or minimum distance remains. The minimum distance should be at least 0.1 mm.

The end magnets can be attached by means of end pieces to the cylinder component. The end pieces can also enclose or envelop the end magnets. In the latter case, the above-mentioned air gap or minimum distance does not remain between the core and the end magnet, but between the core and end piece or casing.

A certain part of the energy required for the operation of the massage device is lost in a closed (gas-tight in the sense of the outside) cylinder component in that air spaces between the core and the end magnet are constantly compressed and expanded. Here, the term of the air spaces on any gas spaces between the outer wall of the core on the one hand and the inner walls of the cylinder member and the end pieces or Endmagneten related. There are also other gas fillings as air in question. Also, the gas pressure may differ from the atmospheric pressure of the environment, in particular be lower ("vacuum" in the sense of less than 0.5, in particular less than 0.2 of the ambient air pressure) Therefore, it is advantageous if these air spaces either communicate with each other or with the Air space outside the cylinder component and / or the housing are connected. This can be done in a variety of ways, which can also be combined with each other as desired. Thus, it is possible that the connection of the air spaces between the core and the end magnet by means of at least one longitudinal bore through the core, at least one outer and extending over the entire length of the core core groove and / or at least one inside of the cylinder component at least over the entire range of motion of Kerns extending cylinder groove is set up. Also, the connection of the two air spaces can be made via a distance between the core and the cylinder component, which is sufficiently large for an air exchange. In this variant, it is recommended to set a gap (with the core held centrally in the cylinder component) between the core and the cylinder component of more than 0.1 mm, preferably more than 0.2 mm, in particular more than 0.5 mm. The connection of the air spaces between the core and the end magnet can also be formed by means of a pipe arranged outside the pipe, wherein the two ends of the pipe are connected to openings in the cylinder component, which in the region of a respective end magnet in the air spaces between the core and the Lead magnets. Instead of such a pipeline, it is also possible to provide a surrounding housing or a cavity extending in accordance therewith. In other words, the two air spaces on either side of the ends of the core communicate pneumatically with each other. In the simplest case, outwardly open openings are provided in the cylinder component, which in the region of a respective end magnet into the air spaces between the core (FIG. 6 ) and guide the magnet. It is also possible that these openings are connected to pipes which lead to the outer surface of the massaging device, to at least one outlet opening, wherein execution and arrangement of the outlet opening can be chosen so that by the resulting air currents an additional stimulation or massage is effected.

The cylinder component limits the radial movement possibility of the core. Thus, it is undesirable if openings are arranged in the cylinder component in the movement region of the core. If there are such openings, they would be temporarily covered by the core and closed to some extent, which bothers. Therefore, openings in the end face of the cylinder component, preferably in the end magnets, in particular in the end pieces, are advantageous. These openings in the end pieces may be formed such that the end magnets do not occupy the entire end surface of the interior of the cylinder component. In the simplest embodiment, the end magnets are formed with a smaller outer diameter than the inner diameter of the cylinder component. In the thereby remaining free part of the tail then one or more openings can be arranged. In the case of several openings, these will then be arranged along a running between the outer periphery of the end magnet and the inner diameter of the cylinder component circle. In particular, the latter embodiment, with, for example, 2 to 20 openings distributed along the circle avoids annoying whistling with high reliability.

It is advantageous if the cylinder component is formed from a metallic material having a permeability of less than 1, in particular aluminum. The advantage over organic polymer materials is that metal tubes are comparatively very precise in production, even the internal dimensions, in particular tubes with a circular inner cross section have only minimal deviations from the circular shape of the cross section, while plastic tubes often have a considerable ovality. The latter bothers example, because it creates unwanted play between the cylinder component and core with the result that rattling noises can occur. In cylinder components made of metallic materials, this is achieved not only purely geometrically by high precision and thus improved fit between core and cylinder component, but also dynamically due to the self-induction (Lenz's rule) in the wall of the cylinder component, which by means of the resulting magnetic fields a radial guidance causes the core and reliably prevents lateral knocking of the core to the inner wall of the cylinder component.

In cross section, the inner wall of the cylinder component and the outer wall of the core basically have any cross-sectional shapes. Should a possible rotation of the core about its longitudinal axis be prevented for technical reasons, it is advisable to have a non-round cross-section, for example square, polygonal or circular with a guide groove extending in the direction of the longitudinal extension and guide projection engaging therein, the groove either in the cylinder component or can be arranged in the core. For reasons of simple and cost-effective manufacturability, however, it is preferred if the inner wall of the cylinder component is circular in cross-section orthogonal to the cylinder component axis Z2 and the core preferably has a cylindrical shape, which is 0.01 to 1.5 mm, in particular 0.01 to 0.5 mm, smaller than the cross-sectional inner radius of the cylinder component is. If cylinder components of metallic materials with a permeability of less than 1 are used, the radius of the core may also be more than 0.5 mm smaller than the cross section of the cylinder component. Even then disturbing noises (rattling) are almost impossible.

The core may be formed from a single bar magnet, but also from a plurality of bar magnets magnetically arranged in series (eg comparatively short length). In the latter case, it is possible to mechnically fix the multi-bar magnet (in addition to the magnetic connection) by means of a wound-up or shrunk plastic sheath against each other and to connect together.

For the core and / or the end magnet all commercially available (same or different) magnetic materials can be used. Particularly inexpensive to manufacture is the use of normal ferrite material, for example based on iron or based on barium or strontium. Smaller dimensions or stronger drives are of course possible with high-performance magnetic materials, such as cobalt samarium, neodymium-iron-boron.

It is preferred if the mass ratio m1: m2 between mass of the core m1 and mass of the device m2 in the range 1:50 to 1: 3, in particular 1:20 to 1: 3 or 1:10 to 1: 3 or 1: 5 , lies. In these contexts, it is expedient if the mass m1 is in the range from 10 to 300 g, preferably 15 to 200 g, most preferably 10 to 100 g. Within the scope of the invention, it is preferable if the stroke of the core in directions parallel to the cylinder axis is in the range of 5 to 150 mm, preferably 10 to 100 mm, most preferably 10 to 60 mm.

In the context of the invention, it is further preferred if the electronic means comprise the means for generating mechanical vibrations with a frequency in the range of 0.1 to 50 Hz, preferably 0.1 to 20 Hz, most preferably 0.3 to 10 Hz, in particular 0.3 to 5 or 10 Hz, drive.

The electronic means can be the means for generating mechanical vibrations so control that the massager vibrates both in the range of harmonic and non-harmonic oscillations. Particularly advantageous is the control of the means for generating mechanical vibrations by applying the coil elements with electrical energy of a pulse duration (within a period) in the range of 5 to 100 ms, preferably 10 to 60 ms, in particular 20 to 40 ms. These data refer to a rectangular shape of the pulses. Otherwise, the triangular, sinusoidal, trapezoidal or polynomial forms are also suitable for the pulses, including combinations of said pulse shapes. Preference is given to pulse shapes with steep edges, such as rectangular or trapezoidal shape.

A change in the period length and thus the frequency can be done by varying the pauses between two pulses - with otherwise unchanged pulse duration. In essence, the control means will be arranged to vary the frequency and the clock ratio, wherein the variation of the clock ratio at a given frequency leads to the above variation of the pulse duration.

It is further preferred if the electronic means control the means for generating mechanical vibrations in such a way that not only uniform vibrations, such as sinoidal (harmonic) vibrations, can be generated, but also vibrations with a clearly non-harmonic character. This has the advantage that the massage effect is improved. For this purpose, the switching pauses between the above-explained pulses (in a user-set speed level) in successive periods and / or within a period by up to 10 to 800 ms, preferably 15 to 600 ms, in particular 20 to 40 ms vary against each other (with unchanged pulse duration). Irrespective of this, the switching pauses of one stage (oscillation) can differ from one another by 2 to 100 times, preferably by 3 to 80 times, in particular by 4 to 60 times.

In the case of all parameters explained above, the lower and / or upper limits of different ranges of the same parameter can also be combined as desired.

The housing can in principle have any customary for massagers form. In one variant, the housing comprises at least one substantially cylindrical housing part, but it may also be formed substantially cylindrical overall. The cylinder component axis is then substantially parallel or coaxial with the cylinder axis of the housing or the cylindrical housing part.

In a preferred embodiment, two mutually coaxial and in the direction of the cylinder component axis spaced excitation coils are arranged. These are alternately energized, so that the core is attracted from the respective end position of the stroke in the opposite direction. In the case of a magnetized core, the two coils are driven with opposite polarity to the core. However, it is also possible with appropriate control to work with only one excitation coil and / or to attract the magnetized core through the excitation coil (s) and / or push away.

The housing expediently has an outer wall formed from a physiologically compatible material. For this purpose, in principle, all customary in medical polymer materials in question, including in particular silicone resins, latex, polyolefins and the like belong.

It is expedient if an inner wall of the cylinder component and / or an outer wall of the core has a sliding coating. As a result, static friction and sliding friction between the core and inner wall of the cylinder component are reduced, so that the energy requirement of the coils is reduced. For this purpose, in principle all sliding coatings customary in the field of mechanics come into question, wherein adhesion coefficients of <0.2 are expediently set up between the surfaces sliding against each other. Merely one example of such a slip coating comprises polyolefins as well as fluorinated hydrocarbons, in particular PTFE. Alternatively, it is of course also possible to guide the core in the cylinder component by means of linear roller bearings or the like. Instead of a lubricious coating, or in addition, conventional lubricants, liquid or pasty, can be used. These include, in particular, oils and greases based on hydrocarbons or silicon.

The energy source is expediently designed as a replaceable battery or as an accumulator. In the latter case, it is recommended that the electronic means additionally have a charging electronics for the accumulator, whereby the accumulator of the massaging device can be charged after use via a conventional power supply. For this purpose, then the housing has an electrical plug connection for connecting the charger. As an alternative to a plug connection, means for wireless charging may be provided, for example an induction loop integrated in the massager. Then, the massager is introduced for charging in a charging station, which in turn has inductive means for feeding electrical energy. Alternatively, the electrical energy can also be transmitted via magnetic connectors become. Compared to conventional plug-in connections, in which the transmission takes place by means of mechanical spring contacts, magnetic plugs make contact for transmitting the electrical energy by magnetic attraction of two magnets (or two magnet pairs). The correct electrical polarity of the DC power supply at both terminals of a plug connection is made possible by corresponding magnetic polarity of the connections, ie the two magnet pairs of a contact pair have reversed magnetic polarity.

It is further preferred if the electronic means are connected to at least one control component, by means of which frequency and / or stroke of the mechanical vibrations of the core in stages or continuously adjustable and can be controlled. These control components can be arranged in or on the massaging device or in the region of one end of the housing or an end face of the housing and set up for manual operation. In the simplest case, it is one or more knobs, such as potentiometers, but also plus / minus buttons and the like are possible in particular in connection with a processor-controlled control electronics. Alternatively, however, it is also possible for control components to be arranged at a distance from the housing and to be connected by wire or wirelessly to the electronic means. In the latter case, a receiver is then integrated in the housing, which is set up for communication with a separate transmitter, wherein the transmitter then comprises the manually operable control component. Alternatively or additionally, the control of the electronic means via acoustic signals (by means of a corresponding control component) take place. In this case, the acoustic signals may include all types of audible sound, in particular in the range of 50 Hz to 10,000 Hz, in particular be formed by human speech. The control over speech is made by words, such as "faster / slower", "more / less" or "harder / softer". The control of noise is via the intensity, the rhythm, the frequency components and / or the timing of the acoustic signals, which are for example music, pulse rate and human utterances, especially groaning. The intensity of the acoustic signals relates to the frequency and / or change of specific frequencies (treble and bass) of the sounds.

The concept of the substantially cylindrical housing or cylinder component is not limited to the exact cylinder shape. Rather, the cross section may differ from the circular shape. Furthermore, the respective cylinder axis may be non-straight. Finally, at least one cylinder end surface of the housing is preferably not made flat, but rounded and in particular, for example, the front end of a male member modeled. Also, the outer surface of the housing can not only be smooth, but also have a topography, for example, with regularly or irregularly arranged knobs have.

A massage device according to the invention can be used for any customary massage purposes of the most diverse body parts in question, for example shoulder / neck area, but also for sexual stimulation in particular of the woman. In any case, the massager is brought into contact with the relevant body part and switched on before or after.

However, the invention also relates to a device for generating vibrations on an object, in particular a stroller, a cot or other Liegestatt for a person, with arranged in a housing electromechanical means for generating mechanical vibrations, with arranged in the housing electronic means for controlling the means for generating mechanical vibrations, and having an energy source, which is connected to the means for generating mechanical vibrations and the electronic means, wherein the means for generating mechanical vibrations, a cylinder component in which a core parallel to a cylinder component axis (Z2), in particular is coaxial with the cylinder component axis (Z2) is guided, at least one coil element whose coil axis (Z3) arranged coaxially to the cylinder component and the cylinder component is comprising, and one impact element, which at each end of the cylinder component and in the interior ang is arranged, and wherein the device is fastened by means of at least one fastening element to the object. This variant is characterized in that the impact elements are designed as end magnets, wherein the respective ends of the core facing the ends of the end magnets have a magnetic polarity which is equal to the polarity of the respective facing ends of the core. It will then be recommended that the electronic means the means for generating mechanical vibrations with a relatively lower frequency, for example, a frequency of 0.1 to 20 Hz, preferably 0.3 to 10 Hz, in particular 0.3 to 5 or up to 10 Hz. Otherwise, all the above and following statements apply to the variant as a massaging device analog. In particular, all the terms "massaging device" attached hereafter, hereinafter and in the claims, are correspondingly replaced by "device for generating vibrations on an object".

In the following the invention will be explained in more detail by means of only one embodiment illustrative figures. Show it

1 : An exterior view of a massage device according to the invention with partial cold cuts and

2 : a schematic cross section of a vibration generator used according to the invention.

3 a force-air gap diagram for different types of impact elements,

4 : A spring-loaded spring deflection diagram for a ferrite end magnet.

In the 1 it can be seen that the massager is a substantially cylindrical housing 1 having. In the case 1 are electromechanical means 2 arranged to generate mechanical vibrations. Furthermore, the housing contains electronic means 3 to control the funds 2 for generating mechanical vibrations. Finally, in the case 1 an energy source 4 provided, which with the means 2 for generating mechanical vibrations as well as the electronic means 3 connected is.

Of the 2 it can be seen that the funds 2 at least one coil element for generating mechanical vibrations 5 , In the embodiment comprising exciting coils 8th . 9 , as well as a displaceably guided ferromagnetic core 6 exhibit. In detail is a cylinder component 7 For example, made of aluminum, which has a magnetic permeability of about 1, wherein the core 6 is guided parallel to a cylinder component axis Z2.

A comparative analysis of the 1 and 2 shows that the cylinder component axis Z2 is coaxial with the cylinder axis Z1, as an alternative, of course, the parallel spaced arrangement of the axes Z1 and Z2 is possible. This moves the core 6 coaxial with the cylinder axis Z1 and in the cylinder component 7 guided. Of the 1 If you continue to take that designed as a knob controller component 12 at one end of the housing 1 is set up by means of which frequency and / or stroke of the mechanical vibrations of the core 6 are adjustable and controllable. Furthermore, one recognizes an on / off switch 13 ,

It is understood in the context of the invention that the cylinder component 7 preferably rigid with the housing 1 connected is. This will cause the mechanical vibration of the core 6 optimal on the case 1 transferred altogether.

Returning to the 2 shows that two mutually coaxial and in the direction of the cylinder component axis Z2 spaced excitation coils 8th . 9 are set up. Furthermore, inside and at each end of the cylinder component 7 arranged end magnets 10 . 11 seen. In the case of a magnetized core 6 become the two exciter coils 8th . 9 alternately and with opposite polarity from electronic means 3 driven. The final magnets 10 . 11 consist for example of ferrite.

A massage device according to the invention typically has a core 6 with a mass m1 which is in the range of 10 to 300 g, in particular 15 to 200 g, preferably 20 to 80 g. The total mass m2 of the massaging device is typically in the range from 100 to 1000 g, in particular from 150 to 500 g, preferably from 200 to 400 g. The electronic means 3 control the funds 2 for producing mechanical vibrations with a frequency typically in the range of 0.3 to 5 Hz. In this case, typically the control of the excitation coils 8th . 9 with a rectangular function or a trapezoidal function with high slope. This will cause high accelerations of the core 6 and corresponding countermovements of the housing 1 induced. The hub H of the core 6 in directions parallel to the cylinder axis Z2 is typically in the range of 5 to 150 mm. The stroke H of the oscillating core corresponds to this 6 the distance of the mutually facing surfaces of the end magnets 10 . 11 minus the longitudinal extent of the core 6 in the direction of the cylinder component axis Z2. Preferably, the stroke is in the range 20 to 80 mm.

The final magnets 10 . 11 are in the embodiment in end pieces 14 . 15 inserted and secured in it. The tails 14 . 15 are in turn stuck to the cylinder component 7 connected or plugged. The attachment or positioning of the end pieces 14 . 15 but can also be done alternatively by another surrounding housing, which the cylinder component 7 and the tails 14 . 15 receives and fixes or positions each other.

In an experimental version of an agent according to the invention 2 for generating mechanical vibrations are the two Do the washing up 8th . 9 slidably mounted along the cylinder component axis Z2 and fixable in different positions, in the simplest case in that the static friction between the coils 8th . 9 and the cylinder component 7 is sufficiently large that when operating the coils 8th . 9 can not move by itself. With such an expedition version, the optimal positions of the coils for each purpose can be determined 8th . 9 can be easily determined along the cylinder component axis Z2. Among other things, these positions are based on the magnetic materials used, the length and weight of the core 6 , the total length of the cylinder component 7 and depend on the desired Freuquenzbereich, but are each easily adjustable and determinable. After the determination, the coils are then placed in series production at the specific positions and fixed firmly.

In the 3 the remaining air gap or its width is shown as a function of the application of force. For this purpose, a cylinder component 7 with an inserted end magnet 10 with the final magnet 10 placed vertically downwards. It became a nucleus 6 introduced and subjected to different weights. The distance between the end magnet 10 and the core 6 was measured in each case depending on the weight. The dead weight of the core 6 was 51.6 g. The results are for two different ferrite materials as final magnets 10 shown. Additionally shown is an experiment wherein the final magnet 10 was replaced by a baffle made of foam, with a correction by deducting the thickness of this baffle was carried out at maximum compression (corresponding to a "gap width" of 0). It can be seen clearly in the diagram that the different ferrite materials have a significantly lower slope of the function, especially with small air gap values, ie the "rebounding" takes place considerably softer than in the case of the foam, with nevertheless comparable weight values without abutment against the final magnet 10 or the foam.

The 4 shows a spring diagram, obtained with the structure which the 3 underlying. It can be seen that the behavior is non-linear, namely progressive.

In principle, the components of a device according to the invention can be designed such that the vibrations of the core are essentially harmonic oscillations or also clearly non-harmonic oscillations. This can be achieved by the exact arrangement of the coils 8th . 9 and their electrical control (duty cycle, pulse shape, etc.) control. In the exemplary embodiment, it is not shown in detail that the end magnets 10 . 11 For example, may have openings or holes for the purpose of air exchange. In addition, reference is made to the general part of the description.
