Description

STIMULATION DEVICE WITH FORM MODIFICATION BY FORM MEMORY ELEMENT

The invention relates to a stimulation device with

Change in shape, which can be used, for example, as a sexual or therapeutic aid, such as a massage device or an exercise device.

Massagers usually serve the mechanical

Influencing the skin, connective tissue and musculature

Stretch, tensile and pressure irritation. The massage effect extends from the treated body of the body over the entire organism and includes the psyche with a.

From practice, massagers that change their outer shape are known. So there are massagers that

can be inflated pneumatically and thus change their volume and thus the shape. Massagers are also known, which can increase their body volume by means of a mechanical turning and sliding technique. A vibrator with a housing and a silicone housing connected to the housing and a vibration-generating electric motor is known from DE 10 2012 109 409 AI.

Furthermore, according to DE 10 2006 005 358 AI a dildo is known, the dildo body consists of a cylindrical part and a front end and electrical heating means and connecting elements for connection to a power source

wherein the heating means are a heating foil arranged tubular in the cylindrical part.

According to US Pat. No. 6,599,236 B1, a dildo has a heating coil as heating element, which can be regulated by a thermostat in order to adapt the dildo to a desired temperature. The material of such massagers or dildos is often made of a rubber-elastic material.

According to DE 10 2012 019 842 AI a massaging device is known with at least one elastomeric deformable wall, with at least one actuator which is arranged to act on a portion of the elastic deformable wall, deforming it, wherein the actuator is formed with an electroactive polymer and the actuator is electrically connected to a control unit arranged in or directly on the massager and can be actuated by means of this control unit.

The massage function is thereby deformed by a deformation element in the interior of a rubber-elastic outer wall, which deforms the outer wall in some areas to the outside. For a continuous force is required, resulting in addition to the friction effects also occurring inside the device to a very high energy consumption.

A disadvantage of the known solutions is that the

Massagers have a predetermined massage function, which can not be subsequently changed and usually are not adaptable to anatomical differences in order to achieve the best possible stimulation.

Another disadvantage of the known solutions that often an electrically driven motor for the movement generation is necessary. Vibration generating electric motors generate annoying and undesirable noise during operation and are subject to unavoidable wear.

The current for the electric drive is known to be provided by means of battery or accumulators. These batteries or accumulators have only a conditional

Lifespan and must be loaded or changed, thus causing a hassle for the user. The object of the present invention is to specify a stimulation device which overcomes the disadvantages of known stimulation devices. This object is achieved by the invention specified in the claims. Advantageous embodiments are the subject of the dependent claims.

The object is achieved by a stimulation device which has a base body and a body attached to or in the base body for contact with a body part of a body

User defined certain contact element, the at least one reversibly deformable contact surface area

wherein at least one for generating a local deformation of the contact element without deformation of the

Basic body trained shaping element is arranged relative to the base body movable on or in the base body, and on or in the base body at least one with the shaping element for generating a movement of the

at least one shaping element operatively connected

Actuating device is arranged, which comprises at least one deformable by applying an electrical current and / or a magnetic field and / or by temperature change shape memory element which is connected on the one hand to the base body and on the other hand with the shaping element and causes a movement of the at least one shaping element by deformation.

The proposed stimulation device can be executed in the concrete case, for example, as a vibrator, dildo, cock ring, masturbator, artificial vagina, anal plug, penis cuff, love balls, expansion tube and the like. The

Stimulation device is advantageous for use as

sexual or therapeutic adjunct to stimulate erogenous zones and / or musculature such as the vaginal and anal muscles.

An external, ie accessible to a user surface of the stimulation device is by a for contact with a Body part of a user specific contact element

formed either the entire surface of the

Stimulation device or the vast majority of

Surface of the stimulation device or only a relatively small part of the surface of the stimulation device forms. This contact element has at least one partial region which is reversibly deformable and the following

Contact surface area is called. Such a thing

Contact element may be made for example of rubber-elastic material such as silicone, latex, thermoplastic elastomers or the like. It may for example be attached to a base body. It can do that

Contact element be attached to the body so that the user accessible surface of the

Stimulation device is partially formed by the main body and partially by the contact element. However, the contact element can also completely or largely envelop the main body.

A stimulation effect is achieved in that on the side facing away from the user of the contact element

Shaping element is movably arranged so that a movement of the shaping element, a local deformation of the contact element, more precisely of the reversibly deformable

Contact surface area, causes or such a deformation on the user-facing surface moves. The movement of the shaping element, in turn, is effected by a shape memory element undergoing a shape change under the influence of an electric current flow, a magnetic field or a temperature change.

For example, such a shape memory element changes a dimension, for example, its length in the case of a wire or thin rod. Such

Shape memory element is for example from a

so-called shape memory alloy (Shape Memory Alloy, SMA). Belong to this material group

For example, alloys such as NiTi, NiTiCu, CuZn, CuZnAl, CuAINi, FeNiAl, FeMnSi and ZnAuCu. Such

Shape memory element may be formed, for example, strip-shaped, wire-shaped, platelet-shaped, band-shaped, spiral-shaped, etc., wherein their shape according to the desired

Function is selected. The induced shape change used to drive a movable forming element may be, for example, an elongation, an extension or shortening, a bend or even a twist.

The shape memory elements may for example have dimensions in the cross section between 0.01 mm and 20 mm and in the length between 10 mm and 200 mm. Further, for example, the shape memory elements in the form of a technical spring (for example, helical spring, torsion spring,

Spiral spring) with wire diameter between 0.01 mm and 5 mm. You can, for example

Activation temperatures between 15 ° C and 100 ° C have.

Furthermore, two or more shape memory elements of different shape memory materials may be present, for example, their shape change at different

Realize temperatures or magnetic fields. The

usable shape memory alloys may have a one-way memory effect and / or a two-way memory effect and / or a pseudoelastic behavior. Depending on the desired function of the stimulation materials with different effects and behavior can be used.

Usually, in shape memory alloys the

Form change thermally or magnetically excited.

Both effects can be exploited. A thermally excited change in shape can be realized by an electric current is passed through the shape memory element, so that the shape memory element due to its resistance heats (direct thermal excitation) or changed the temperature of the shape memory element from the outside is, for example, by supply or removal of heat, for example by a heating or cooling device or by changing the ambient temperature, for example by the action of body heat (indirect thermal

Suggestion).

For example, shape memory alloys can be used which are at higher temperatures than the

Application temperature have no change in shape and change in temperature to the application temperature their shape. For example, the stimulation device can be heated to a temperature of 50 to 60 ° C and then cools to room temperature when applied to stimulate skin or muscles and deforms.

On the other hand, this thermally excited shape change can also be realized by shape memory alloys which have no change in shape at lower temperatures than the application temperature and change their shape when the temperature is raised to the application temperature. For example, the stimulation device may be at room temperature and when inserted into vaginal or anal orifices and

Temperature increase to body temperature of about 38 ° C are heated and deform it.

However, the thermal activation can also be realized by passing an electrical current and the resulting heat of resistance, by a heating element or heating medium, for example a heating element, or by a chemical, exothermic reaction, for example a sodium acetate trihydrate solution.

Which either by current flow through the

Shape memory element, by generating a the

Shape memory element penetrating magnetic field or changing the temperature of the shape memory element generated shape change of the shape memory element, which for the Movement of the shaping element is causal, is silent and thus superior to known stimulation devices. In addition, the use of a shape memory element as a drive of a movable shaping element allows a nearly inertia-free, ie very responsive control of the drive of the shaping element over wide frequency ranges and with very sensitive adjustable amplitude of

generated movement.

With the proposed stimulation device, it is possible to exercise by changing the shape of several successive or simultaneously acting functions for stimulation and thus better stimulation of the respective

Reach the stimulation area.

Possible producible shape changes that the proposed stimulation device by activating the

Shape memory alloy can include curvatures, curves, bends, multiple elevations and depressions, directional shape changes, strains or changes in length or spiral formations. These changes in shape can be at

Use of additional elements to additional

Shape changes of the outer shell lead.

With this stimulation device can successively or simultaneously individual areas of a contact surface of the

Stimulation device, such as an outer shell, change its shape. Here, for example, a one-time change in shape during the application, a pseudoelastic multiple change in shape and / or a change in the

Form change can be achieved during the application, with each change in shape after application back to the

Initial state can be traced back.

In this case, an elastic sheath, for example, be designed so that it returns the or the shaping elements back to their original shape, or the or Shape memory elements return to their original shape after the excitation is complete.

As already described above, this can be at least one

Shaping element between a first position and a second position to be movable back and forth, wherein the at least one shaping element does not deform the contact surface area in the first position and deformed in the second position.

For example, the deformable contact surface area in the first position of the shaping element undeformed, and thus the user-facing surface of the

Smooth stimulation device while the

Forming element in its second position causes a local deformation of the contact surface area, the

For example, causes a thickening of the stimulation device. However, a single shaping element may also be designed such that in the second position it is two or more close to one another, for example

Deformations such as bulges of the contact surface area or the like generated.

However, the at least one shaping element can also be movable back and forth between a first position and a second position such that the at least one

Forming member deformed the contact surface area in both the first and in the second position, and the deformation generated by the shaping element during the movement of the forming member over the

Contact surface area moves. In other words, the deformation travels across the user facing surface of the stimulation device.

It can further be provided that the actuating device at least one of the movement of the at least one

Shaping element or an elongation of the at least one Has shape memory element counteracting return element. Such a return element may for example be an elastic element such as a spring or the like, but also an additional shape memory element. If the restoring element acts on the shaping element, the elongation of the shape memory element becomes due to the operative connection between the shaping element and

Reverted shape memory element while the

Reset element in the other case directly on the

Forming element acts and reverses its elongation.

According to one embodiment, it is provided that the

Actuator one with at least one

Shape memory element and at least one

Forming element force-transmitting connected

Transmission device comprises. Such

Transmission device can for example have a Bewegungsungsumformende function. For example, an elongation of a shape memory element that acts linearly can be converted into a rotational or pivoting movement of the shaping element. Alternatively or additionally, a

Transfer device be designed so that it amplifies a generated by the elongation of a shape memory element movement of a shaping element or

weakens. For example, a transmission device may be designed as a transmission.

For this purpose, for example, be provided that the

Transmission device has at least one lever and / or at least one scissors mechanism and / or at least one crank disc and / or at least one guide element. A guiding element in this sense can

For example, a linear guide for guiding a

Forming element along a straight guideway or along a guide curve. According to a further embodiment it can be provided that at least two shaping elements with each other

are actively connected. In this case, the operative connection between the two or more shaping elements may be such that the coupled shaping elements act in the same direction or in opposite directions on the contact element. This means a co-acting of two or more

Shaping elements on the contact element, that the coupled shaping elements in their respective first position generate no deformation and each generate a deformation in their respective second position, i. always generate a deformation or a movement from their respective first position into their second

Position causes a movement of the respective deformation in the same direction, i. the deformations generated by the shaping elements move together in the same direction. An opposing action of two or more shaping elements on the contact element means that the coupled shaping elements always alternately produce a deformation or the deformations generated by the shaping elements move in opposite directions.

Furthermore, it can be provided that two

Shape memory elements with opposite directions of action are operatively connected to the one or more shaping elements. This can either be used to operate, for example, two shaping elements in opposite directions, as already described above, or an expansion of a

Shape memory element by the action of another

Undo shape memory element, as also described above.

According to one embodiment, it is provided that the

Basic body as a first, the shape memory element or the shape memory elements receiving housing part is formed and at least one shaping element is designed as a second housing part, which is movably connected to the first housing part. For example, a first and one or more second housing parts

together form a housing defining the outer shape of the stimulation device, wherein the or the second housing parts due to their relative mobility

cause common or in each case a local deformation of the stimulation device relative to the first housing part.

Furthermore, it can be provided that the contact element intended for contact with a body part of a user is designed as a rubber-elastic casing which encloses at least the main body and the one or more shaping elements. Forming the base body and the one or more shaping elements together a housing defining the outer shape of the stimulation device, the sheath may be formed according to this outer shape, so that they to the

Housing parts fits tightly. During a movement of a

Shaping element is then elastically deformed in the vicinity of the shell, so that, for example, the

Stimulation device thickened.

According to a further embodiment it can be provided that on or in the main body at least one

Energy storage for storing electrical energy

is arranged. Although it is also possible to supply the electrical energy required for the operation of the stimulation device from the outside, for example by connecting the stimulation device to a power cable, it is advantageous for good handling of the stimulation device if it is cordless. This can be done by the

Arrangement of an energy storage directly on or in the

Stimulation device can be achieved.

In one embodiment, it is provided that the

Energy storage at least one rechargeable Accumulator includes. This avoids the user having to open the stimulation device to non-rechargeable

Replace batteries as soon as they are exhausted.

Advantageously, it can further be provided that at least one receiver coil to or in the base body

contactless supply of electrical energy is arranged. In this way, for example, in the

Stimulating device arranged accumulator contactless charging. Metallic contacts on the outside of the stimulation device are thus not required, whereby the stimulation device is even safer to handle and can be made waterproof in a simple manner.

According to a further embodiment, it may be provided that a control device for influencing the movement of the one or more shaping elements is arranged on or in the base body, with the or the shape memory elements and / or with an electromagnet and / or with a

Heating device is electrically connected. The

Control device can be designed, for example, so that it outputs a pulsating or continuous signal. In this case, "pulsating signal" means that between two movement processes in which a shaping element is respectively moved from a first to a second position and back, during a certain period of time no

Movement takes place. In a "continuous signal", however, a movement from the first to the second position and back takes place in constant change, without the forming element comes to rest

Stimulation device on several shaping elements, each independently with a

Shape memory element operatively connected and from this

are driven, it is advantageous to control the individual shaping elements independently and separately from each other. That way, you can create complex ones Stimulation programs are realized.

Furthermore, it can be provided that the control device for the periodic activation of the or

Shape memory elements in the frequency range of 5 Hz or less, preferably 3 Hz or less, in particular 1 Hz or less is formed. Known stimulation devices

vibrate at frequencies many times higher than these values. The stimulating effect of such

Stimulation devices are based on an irritation of body parts caused by a high-frequency solid-state movement of the device, which come into contact with it. It has been found that a stimulation that is achieved on a periodic, low-frequency point force on treated body parts a much more pleasant and intense stimulation effect. This type of stimulation is perceived as particularly pleasant at the indicated frequencies, as well as the punctual effect on

treated body parts of a user.

In another embodiment, it is provided that there is at least one operating element for setting a frequency and / or expansion amplitude of at least one

Has shape memory element.

For example, a direct influence of frequency or / and amplitude by the user may be possible.

For this purpose, for example, a button for on and

Turn off the stimulation device may be provided.

Furthermore, for example, for each individually controllable shaping element each have a button for adjusting the frequency and a button for adjusting the amplitude may be provided, wherein the frequency or the amplitude either

be increased or decreased continuously as long as the respective button is pressed, or the frequency or the amplitude with each push of the corresponding button gradually increased or decreased. Likewise for the adjustment of the frequency and the amplitude in each case a pair of buttons to be provided, one of which causes an increase and the other a reduction of the frequency or the amplitude. In other embodiments, an indirect influence on frequency or / and amplitude by the user

be possible. For this purpose, the stimulation device

stored for example in the control device

Have stimulation programs that have different

Combinations of frequencies and amplitudes generate, wherein both the frequency and the amplitude in the time course of a program can be varied. The

Alternatively, programs may be stored in an app running on a mobile device. Such an app can be used as a remote control for the same time

Stimulation device be executed.

The stored programs can be used as above for user selection of frequency or / and amplitude

be available for example via a control. For this purpose, according to one embodiment, for example, a single button may be provided, the first pressure the

Pacing device turns on and retrieves a first stored program. If the button is pressed again, the next stored program will be recalled, and so on, until all stored programs have been selected once. If the button is then pressed again, this will cause the stimulation device to be switched off. According to another embodiment, a button is the on and

Switch off and another button of the program selection.

Alternatively, a pair of buttons may be provided for program selection, one of which calls the stored programs in ascending order and the other calls the stored programs in descending order.

It is understood that instead of buttons others Controls can also be used

For example, toggle switch, rotary switch and the like. A particular advantage of buttons is that they are water protected in a simple manner under or behind a rubber-elastic contact element, such as a

Silicone shell, can be arranged, because they still easily due to the elastic property of the shell

are operable.

However, such solutions are also included, in which the one or more operating elements are components of a remote control, so that the stimulation device itself no

Controls must be attached. If the remote control is an app running on a mobile device, the controls can be in the form typical for apps,

for example, as a touch-operated, on the

Screen of the mobile terminal shown buttons, sliders or the like to be executed, whose

Functions corresponding to those described above.

Each of FIGS. 1 to 4 shows a schematic view of a longitudinal section through an exemplary stimulation device according to various embodiments. In this case, in all cases shown, a contact element intended for contact with a body part of a user is at one

Outside of a rod-shaped housing arranged. However, the presented principles and mechanisms are also applicable to embodiments having a different shape, for example stimulation devices with a hollow cylindrical housing or base body, in which a contact element intended for contact with a body part of a user forms an inner surface of the hollow cylinder.

In the embodiments shown is one each

Contact element 5 formed as an elastic outer shell made of silicone. The contact element 5 encloses a base body 1 formed by two first housing parts 3. In the exemplary embodiments according to FIGS. 1, 2 and 4, in each case a shaping element 2 is movably arranged on the base body 1, which is at the same time designed as a second housing part 4. In the exemplary embodiment according to FIG. 3, two shaping elements 2 are movably arranged on the base body 1, which are each designed as a second housing part 4 at the same time. The first housing parts 3 and the second housing part or parts 4 together define the basic shape of the stimulation device, which is outwardly of the

Contact element 5 is limited.

Inside the stimulation device is one each

Shape memory element 7 arranged, which in the embodiments shown as a clamped wire Shape memory alloy executed and guided by guide elements 12. The shape memory element 7 is respectively arranged in the base body 1 and connected on one side with a first housing part 3 and on the other side with the shaping element 2 and in the embodiment of FIG. 3 with the two shaping elements

operatively connected. The shape memory element 7 is by a return element 8, which is designed in the embodiments as a compression spring, in the initial state below

Tensile load.

The shape memory element 7 is provided with an energy store 13, which in the exemplary embodiments in each case as

rechargeable accumulator is executed, and a control device 14 electrically connected, so that a

Current flow can be generated by the shape memory element, wherein the electrical connection is shown in a highly schematic. The control device 14 can

For example, be operated by one or more buttons by the user. As soon as current flows through the shape memory element 7, it contracts against the applied tensile stress. As soon as no current flows, the return element 8 pulls the shape memory element 7 back into the initial length. By appropriate programming of the

Control device 14, the shape memory element 7 can be driven pulsating and thereby generates a pulsating movement of the or the shaping elements 2, thereby causing one or each deformation of a reversibly deformable contact surface area 6 of the contact element 5.

For the preparation of the active compound between the

Shape memory element 7 and the or the

Shaping elements 2 are formed in the embodiments transmission means by lever 9, wherein at the embodiment of FIG. 3, a crank 11 takes over the function of the lever. In the

Embodiments are lever 9, which are components of the respective guide means, guided in guide elements 12.

In the embodiments of FIGS. 1 and 2, the shaping elements 2 each have a dome shape and are characterized by alternating extension and shortening of

Shape memory element 7 linearly displaceable. In contrast, the shaping elements 2 in the exemplary embodiments of FIGS. 3 and 4 are articulated to a respective first housing part 3 and pivotable about the articulated mounting, whereby a deformation of the deformable contact surface area 6 of the contact element 5 is achieved.

In the embodiment of FIG. 5 is a

Shaping element 2 articulated in a base body 1 formed from two first housing parts 3. The

Contact element 5 does not cover the entire

Stimulation device, but only not the first

Housing parts 3 sealed areas. The

Shaping element 2 is operatively connected to a return element 8 in the form of a helical spring. One

Shape memory element is connected on one side with a first housing part 3 and on the other side directly to the shaping element 2. An electric

Actuation of the shape memory element 7 causes a

Pivoting movement of the shaping element 2, whereby the deformable contact surface area 6 of the contact element is locally deformed.

FIG. 6 shows six exemplary embodiments of various other mechanisms of action proposed by the invention. This is very strong

schematized representations that do not show all the features of the respective stimulation device, because they only should illustrate how a stimulation device can be designed according to the invention.

In FIGS. 6A and 6B, the deformation is effected in the simplest way by a pivot lever which locally deforms the contact element 5. In the case of FIG. 6A, the lever 9 is moved from the bottom up when the shape memory element 7 is actuated. In the case of Fig. 6B, the lever 9 is moved upon actuation of the shape memory element 7 from top to bottom. This corresponds to the operating principle of the exemplary embodiment of FIG. 5. In specific embodiments, for example, the lever 9 itself can simultaneously be the shaping element 2.

In the embodiments of FIGS. 6C and 6D, a deformation of the contact element 5 is achieved by two or more levers 9, for example, around the circumference of the

Stimulation device can be distributed. In the case of FIG. 6C, the shape memory element 7 is connected to the contact element 5 at the highest point. Are also the free ends of the lever 9 connected to the contact element, so spread the lever 9, when the shape memory element 7 is shortened, so that the contact element 5 is deformed. In the case of Fig. 6D, four levers are of the type

Scissor mechanism 10 connected together and in

guided in horizontal direction in guide elements 12, so that a shortening of the shape memory element 7 a

Outward movement causes the connection points of the lever, which in turn leads to a deformation of the contact element 5.

In the embodiments of FIGS. 6E and 6F, deformation of the contact element 5 is effected at a plurality of locations. The embodiment of Fig. 6E is similar to that of Fig. 6C, but here two pairs or groups of levers 9 are arranged with the same

Shape memory element 7 are operatively connected and operated in the same direction by this. The By contrast, an exemplary embodiment according to FIG. 6F represents an example of a stimulation device which has a plurality of pairs or groups of levers 9 operatively connected to one and the same shape memory element 7, each of which is connected to a shaping element 2, each one

Forming element 2 constantly a deformation of

Contact element 5 causes. An actuation of the

Shape memory element 7 causes in this case a

Displacement of the shaping elements 2 along the

Longitudinal axis of the stimulation device, and thus one

Displacement of the generated deformations.
