Description

The invention relates to a plug-in element for connecting a massage device for massaging body parts, in particular the genitals, to an energy source.

Massage devices of the type mentioned are also known as vibrators, which are available in different shapes and sizes. These include battery operated vibrators with direct control or cable control and vibrators with remote control, e.g. B. via the Bluetooth protocol. From the WO 02/38100 A2 For example, a massage device for intimate stimulation is known, in which a cable or cord is provided at one end of the massage body and serves as an antenna and / or charging cable. However, a disadvantage of the known massage device is, inter alia, that the socket at the free end of the return cord is not designed to be liquid-resistant. Liquid can penetrate into the opening of the socket, which can lead to corrosion and thus to malfunction of the device. In addition, the design of the charging cable as an antenna is limited to certain radio frequencies and antenna types by the dimensions of the cable. In particular, it is not possible to use current standards of mobile data communication, such as. B. Bluetooth, IEEE 802.11 (WLAN), GSM, UMTS and the like for wireless data transmission between a remote control device, such as. B. a smartphone, and to use the massage device.

It is therefore the object of the present invention to at least partially overcome the disadvantages mentioned above and to enable a reliable liquid-proof function, a simple structure and a robust and inexpensive manufacture of massage devices.

This object is solved by the subject matter with the features of claims 1 and 12, respectively. Advantageous embodiments are the subject of the respective dependent claims.

According to the invention, a plug-in element for connecting a massage device to an energy source is provided, the plug-in element comprising a housing which has two charging electrodes for connection to an energy source and a control device, a wireless data communication device and a circuit board antenna for Transmits and receives radio signals from the wireless data communication device. The plug-in element further comprises a cable that emerges from the housing for connecting the plug-in element to the massage device, the plug-in element being provided at a first end of the cable and an opposite second end of the cable being set up for connection to a massage device. The housing, the cable and the connection between the housing and the cable are liquid-resistant.

In this way it is achieved, on the one hand, that liquid penetration into the plug element and thus into the area of sensitive electrical components of the massage device is avoided. The components housed in the housing of the plug-in element are protected from liquid and their reliable function is guaranteed. The arrangement of the circuit board antenna in the plug-in element reliably ensures communication between the wireless data communication device and a remote operating device, since the plug-in element is always arranged outside the body when a massage device is used properly. Due to the common arrangement of the wireless data communication device and the circuit board antenna in the housing, a malfunction of the massage device can also be prevented by disturbing the received signals during the transmission of the signals between the circuit board antenna and the data communication device. In particular, the high-frequency antenna signal is exposed to as few interference signals as possible and the influence of the current flow due to the USB charging voltage source (DC voltage) is as low as possible. Printed circuit board antennas are also suitable for sending and receiving signals according to current data transmission standards. In addition, all of the components of the massage device that are relevant for the control are arranged in the plug-in element, which on the one hand enables a compact and simple structure but also enables inexpensive production. In particular, the structure of a massage part or vibrating body of the massage device can be considerably simplified since it only has to have a vibration generating device and an energy store, while other electrical components, in particular the sensitive electronic components, can be swapped out into the plug element. Due to the independence of the plug element from the vibrating body, the plug element can be used for a large number of differently designed vibrating bodies, as a result of which the production costs can be further reduced. After all, not only a vibrating body is sufficient the massage device, which is inserted into a body opening, but also the cable and the plug-in element due to the liquid-resistant design, the hygiene regulations that apply to such devices, for. B. EP67 (DIN EN 60528). The cable and the plug-in element can thus also be cleaned with simple means and do not offer any openings into which liquid could penetrate such that the function of the massage device is impaired.

The plug element is particularly advantageous and the charging electrodes are USB compatible. With the USB technology, a very widespread method for charging the energy store of the massage device or for data transmission can be used. The flat plug element has a configuration similar to that of a USB-A plug, which can be inserted into a corresponding USB socket. Such connection sockets are available on a large number of devices, for example on PCs, laptops, notebooks, tablet computers, power supply units and the like, and provide a sufficient charging current in accordance with the USB standard (up to 500 mA at 5 volts according to USB 2.0). In addition, the plug element can be made very small in comparison to conventional power supply plugs. Due to the low current consumption and the low voltage, the handling of the USB-compatible plug element is harmless for the operator in contrast to a conventional 220 V power plug.

In a preferred embodiment, the housing has a length, a width and a height, the length being greater than the width and the ratio of length to height being less than 10: 1, preferably less than 8: 1 and more preferably less than or is 6: 1, and the length to width ratio is less than 10: 1, preferably less than 7: 1, and more preferably less than or equal to 3: 1. The housing preferably has a size of at most 50 mm × 30 mm × 20 mm, more preferably of at most 40 mm × 20 mm × 10 mm and even more preferably of at most 35 mm × 15 mm × 6 mm. As a result, the plug-in element is designed to be relatively small, so that when the associated massage device is used, it is not perceived as disruptive and does not negatively influence the handling of the massage device. At the same time, it is easy to grasp and ergonomically manageable.

In one embodiment, the plug-in element further comprises an actuating element which is formed in a surface of the plug-in element. The actuating element is used for direct actuation of the massage device by means of the control device in addition to remote operation and thereby enables the massage device to be used even without a remote operating device. The control element can be designed, for example, as a pressure element on the surface of the housing of the plug-in element and is thus easily and easily accessible and operable even when using the massage device.

The housing of the plug-in element preferably also has a grip area on its surface. The grip area is formed near the end of the plug element at which the cable is connected to the plug element. This enables simple insertion and removal in or out of a charging socket. The grip area can be formed by corrugation or a bulge on the surface of the plug element. Other expedient configurations that do not influence the function of the plug element and the antenna element are also possible. In particular, the control element can also be designed as a grip area in order to ensure good haptics and usability. Alternatively, the grip area can also be arranged on a side surface opposite the actuating element or on a surface arranged laterally to the actuating element in order to avoid undesired actuation of the massage device.

The charging electrodes, the circuit board antenna, the wireless data communication device and the control device are particularly preferably arranged on a common circuit board. The printed circuit board antenna, also called a printed antenna, is designed, for example, in such a way that it can be applied inexpensively in a suitable form as a metal layer, in particular a copper layer, on a conventional printed circuit board. This makes it possible to achieve a compact component, which can save space and costs. In addition, all electronic components of the massage device that require a printed circuit board are then arranged together on a printed circuit board in the plug-in element, which reduces the manufacturing outlay, the production costs and the complexity of the entire massage device by reducing the individual parts. Additional circuit board-bound components in the massage device are not required. A particularly simple construction results if the charging electrodes, the circuit board antenna, the data communication device and the control device are arranged on one side of the circuit board. In particular, this also allows the height of the structure to be reduced. Alternatively, the charging electrodes, the circuit board antenna, the data communication device and the control device can be distributed in any combination on two opposite sides of the circuit board. As a result, the height of the structure is increased, but the area required for the printed circuit board is reduced. By cleverly arranging the components on the circuit board, an efficient and space-saving construction can be achieved. It is also possible to arrange the charging electrodes on both sides of the board or printed circuit board, so that the plug-in element can be inserted in a USB socket or corresponding other charging socket in a user-friendly manner in all (two) orientations. This requires logic in the control device that recognizes the positive pole and negative pole accordingly.

Another advantage is the PCB antenna for sending and receiving radio signals according to Bluetooth (according to IEEE 802.15.1), ZigBee (according to IEEE 802.15.4), ANT, NFC (Near Field Communication), WLAN (according to IEEE 802.11), GSM, UTMS, LTE, 5G or another mobile data transmission standard. In particular, this enables the transmission and reception of radio signals from a large number of different remote operating devices, in particular from smartphones and computers, with the required reliability and speed.

It is further preferred that the cable has two strands. The cable connects the plug-in element to a vibrating body of the massage device and consequently serves to transmit current while the massage device is charging and to transmit signals for controlling or actuating the massage device. It is preferred that the two strands are formed separately from one another and are each waterproof. This ensures that the transmitted signals are not undesirably influenced or disturbed and that each of the lines is reliably protected from the ingress of a liquid.

It is further preferred that one of the strands comprises at least one electrical line for connecting the charging electrodes to an energy store of the massage device and that the other strand comprises a signal line for connecting the control device to a vibration generating device of the massage device.

The housing is preferably formed from a biocompatible plastic or has an envelope made from a biocompatible plastic. Likewise, the cable preferably has a sheath made of a biocompatible plastic. As a result, the components such as circuit board, circuit board antenna, data communication device and control device and the connection points to the cable harnesses z. B. protected against corrosion. It also ensures that the plug-in element is suitable for use with a massage device on and in the human body.

It is particularly preferred if the housing is manufactured by means of injection molding or the biocompatible plastic covering is applied by means of injection molding. This creates an integrally formed plug-in element that offers as little contact surface as possible for impairment or processing from the outside.

The material of the plastic or the plastic casing is preferably a thermoplastic, such as. B. acrylonitrile-butadiene-styrene copolymer (ABS) or a comparable plastic with similar properties. These thermoplastics are insensitive to commercially available lubricants and cleaning agents, and are tasteless and odorless.

The charging contacts of the plug element advantageously have a coating with a metal or a metal alloy, e.g. B. in the form of gilding with gold or a gold alloy or in the form of a refinement with another metal or a metal alloy. In particular, corrosion of the charging contacts must be avoided and reliable power transmission guaranteed.

According to the invention, a remotely controllable massage device suitable for massaging body parts, in particular the genitals, comprises a plug element, as described above, and a vibrating body, which comprises a vibration generating device and an energy store, the vibrating body being connected to the plug element only by means of the cable.

In this way, a massage device is provided which is particularly easy to handle and inexpensive to manufacture. In particular, only those are in the vibrating body To provide vibration generating device and the energy storage device, which have a relatively high space requirement, while other electronic components are outsourced into the plug element. The vibrating body itself is therefore easier and easier to handle. Due to the smaller number of components to be accommodated in the vibrating body, the external shape, in particular the size and contour, of the vibrating body is less predetermined by the components to be accommodated, but can be adapted more flexibly to different needs and areas of application. Since the plug-in element can be used in a large number of different massage devices, the manufacturing costs which are lower due to the higher number of pieces which can be achieved have an advantageous effect on the costs of the massage device.

The vibrating body is preferably made of silicone, TPE or another suitable thermoplastic. From a hygienic point of view, these materials are not critical and have a pleasant and particularly suitable feel for use on or in the body. The material of the massage device is preferably UV-resistant, odorless and tasteless, although different colors can also be used.

In particularly preferred embodiments, the vibration body is designed as a shock wave vibrator or as a vibration vibrator. Basically, the plug-in element according to the invention can be used with all common types of vibrators.

The vibrating body is preferably free of printed circuit boards. This ensures that all components bound to the printed circuit board are shifted into the plug element, which results in a simpler and more cost-effective construction.

In particular, it can be achieved that the entire control system of the massage device is arranged in the plug element.

Fig. 1 shows in a perspective view an embodiment of the plug element 1 according to the invention for connecting a massage device, in particular a vibrator with an energy source, such as. B. a USB socket.

The plug-in element 1 is designed as a flat plug and comprises a housing 2 and a cable 4. The cable 4 emerges from the housing 2 and connects the plug-in element 1 to a vibrating body (not shown), as will become apparent below Fig. 5 results. The plug-in element 1 has, on an upper side 2 in the longitudinal direction of the plug-in element 1, charging electrodes 6 arranged parallel to one another and designed to be compatible with a USB-A connection. In the illustrated preferred embodiment of the plug-in element 1, this further comprises an actuating element 8 for actuating the massage device.

Instead of the actuating element 8 or in addition to the actuating element, a grip area can be provided on a surface of the housing 2, which, for. B. is formed as a bulge. The grip area serves to make it easier to handle the plug element 1 when plugged into a corresponding USB socket or when removing it. The grip area is designed in such a way that the plug-in element 1 is easy to grip on it and has good haptics. For this purpose, the grip area can for example be corrugated or have a projection on which the user can grip well. The grip area can optionally extend to the side surfaces including the edges of the housing.

As in Fig. 1 It can also be seen that in the preferred embodiment the cable 4 comprises two strands 10 which run separately from one another between the plug element 1 and the vibrating body. It is conceivable that each of the two strands 10 emerges from an opening of the housing 2, or that the cable 4 has only one strand in the region of the housing 2, which is divided into two strands 10 after emerging from the housing 2. In this case, the effort for sealing the connection between the cable 4 and the housing 2 is reduced. It is of course also possible for the cable 4 to consist of a single strand throughout, which encapsulates all the lines running between the plug element 1 and the vibrating body records.

The individual components of the plug element 1 according to the invention are described below with reference to FIG Figures 2 to 4 described in more detail.

The plug-in element 1 according to the invention comprises a control device, a wireless data communication device and a circuit board antenna for transmitting and receiving radio signals from the wireless data communication device, which are accommodated in the housing 2 and are preferably arranged on a common circuit board.

Fig. 2a shows in a perspective view schematically a circuit board 12 on which various components are applied and connected to each other. In Fig. 2a the underside of the printed circuit board 12 can be seen. The two charging electrodes 6 are applied parallel to one another in the longitudinal direction on the printed circuit board 12. The dimensions, ie in particular the distance and the length of the two charging electrodes 6, are dimensioned such that the plug element 1 can be inserted into a corresponding USB socket for charging the massage device. The (in the Fig. 2a and 2 B Contacting of the charging electrodes 6 with the connections of the two cable strands 10 takes place in a known manner, preferably in corresponding recesses in the printed circuit board 12. In the preferred embodiment, in which the cable 4 is formed in two strands 10, the first strand is a simple cable with a strand, the end of which is connected to the plus charging electrode. The second strand 10 of the cable 4 is designed as a coaxial cable, the outer conductor being connected to the charging electrode 6 defined as the ground pole.

An actuation switch 14 is also arranged on the underside of the printed circuit board 12, which in the assembled state of the plug element 1 follows Fig. 1 abuts an actuating section of the actuating element 8. Pressing the actuating element 8 by the user actuates the actuating switch 14.

Fig. 2b shows the top of the circuit board 12 schematically in a perspective view, the circuit board antenna 16 being applied to the circuit board 12 as a conductive layer using known technology. Such a circuit board antenna 16 is characterized by a compact design. In the invention, it is advantageous that the circuit board antenna 16 in the plug-in element 1 is located away from the printed circuit and the components of the wireless data communication device, since secondary excitations and thus interference due to the high-frequency properties of the circuit board antenna 16 are reduced.

The shape of the printed antenna path (s) of the printed circuit board antenna 16 is optimized for good radiation characteristics, a high degree of efficiency in reception and transmission, and for a sufficient bandwidth. It is understood that the circuit board antenna 16 in Fig. 2b is only indicated schematically and can be arranged or printed on the printed circuit board 12 in a manner known to the person skilled in the art in adaptation to the given requirements.

The data communication device 18 and the control device 20 are further arranged on the printed circuit board 12 and are contacted in a known manner with conductor tracks printed on the printed circuit board 12. The data communication device 18 converts the signals received from the circuit board antenna 16 and makes them available to the control device 20. The control device 20 in turn controls the vibration generating device of the massage device in accordance with the received commands. The control device 20 and the wireless data communication device 18 are supplied with power by an energy storage device of the massage device and supplied by a remote control device, for example a smartphone, a PC or a similar mobile control platform, with suitable radio signals for control purposes.

The control device 20 can additionally have a data storage device for storing program sequences, which makes it possible to program the massage device with internally or externally created vibration sequences, to store the vibration sequences and to control the massage device accordingly. In this case, the control signals are supplied from the data storage device. Direct control via the remote operating device is also possible. An additional, direct control via the actuating element 8 is also possible.

Correspondingly, the control device 20 is connected to the actuation switch 14 and also to the data communication device 18 by means of printed conductors printed on the printed circuit board 12. A control signal output by the control device 20 is transmitted to one of the strands 10 and to a vibration generating device of the massage device by means of a conductor track printed on the printed circuit board 12. The data communication device 18 is connected at least to the printed circuit board antenna 16 via printed conductor tracks. In the embodiment described above, the control device 20 is electrically connected to the coaxial line, for example to the inner conductor of the coaxial cable, also called a soul. It is also possible to make the electrical connections described herein by gluing or by another suitable contacting technique.

The structure of the printed circuit board 12 with the components arranged thereon makes it possible to use standard components which are commercially available and are produced in large quantities, as a result of which costs can be saved. The concentration of the components usually arranged on printed circuit boards in the plug-in element 1 also eliminates the need for further printed circuit boards in the vibrating body.

Fig. 3 shows the housing 2 in a perspective view. The housing 2 is preferably produced by injection molding and ideally injection molded directly onto the printed circuit board 12. The housing 2 has a flat section 22, on the upper side of which there is an opening which at least releases the charging electrodes 6 on the printed circuit board 12 to such an extent that contact with an energy source is possible. The flat section 22 of the housing 2, including the printed circuit board 12 contained therein, is designed such that it can be inserted into conventional USB sockets. To provide enough space for the rest of the To provide printed circuit board 12 arranged components, the housing 2 may have larger dimensions adjacent to the flat portion 22.

The housing 2 is preferably produced on the printed circuit board 12 by injection molding and consists of a thermoplastic material, for example of acrylonitrile-butadiene-styrene (ABS). Alternatively, the housing 2 can also be extrusion-coated with a corresponding covering made of thermoplastic material. Both variants make it possible to provide a housing which is as closed as possible and thus liquid-tight and which securely accommodates the electronic components, only the charging electrodes 6 being exposed and, moreover, an adequate seal being created.

The housing 2 has a length L, a width B and a height H, the length being greater than the width. Preferably the ratio of length to height is less than 10: 1, preferably less than 8: 1 and more preferably less than or equal to 6: 1. It is further preferred that the ratio of length to width is less than 10: 1, preferably less than 7: 1 and more preferably less than or equal to 3: 1. For example, the housing has a size of at most 50 mm × 30 mm × 20 mm, more preferably of at most 40 mm × 20 mm × 10 mm and even more preferably of at most 35 mm × 15 mm × 6 mm.

On an upper side 24 of the housing 2, a further opening 26 can be provided, which has a contact area that receives the actuating element 8. The actuator 8 is with reference to FIG Fig. 4 Described in more detail and preferably arranged on the printed circuit board 12 before the enclosing housing 2 is attached.

The actuator 8 after Fig. 4 preferably consists at least partially of a flexible plastic. The actuating element 8 has a contact area 28 which stands out from a body 30 of the actuating element 8. A surface of the body 30 preferably bears in a form-fitting manner on the inside of the housing 2 and the contact region 28 extends into the opening 26 on the upper side 24 of the housing 2. The contact region 28 is preferably flush with the upper side 26 of the housing 2. However, it may also be desirable for the contact area 28 of the actuating element to extend beyond the upper side 26 of the housing 2 in order to lift off from it. This enables reliable actuation, even if the plug-in element 1 cannot be seen by the user. However, the contact surface 28 can also be a means, in particular Emphasis, as in Fig. 4 is indicated by the circular section on the contact surface 28 in order to haptically signal the user the optimum pressure point for actuating the actuating element 8. On an underside of the contact surface 28, the actuating element 8 is designed such that it actuates the actuation switch 14 on the printed circuit board 12 when pressure is exerted on the contact surface 28. For this purpose, for example, a projection can be provided on the actuating element 8. Incidentally, the actuating element 8 is formed in the housing 2 with regard to a reliable receptacle and comprises, for example, openings 32 or latching elements 34 for connection to the printed circuit board 12 and the housing 2.

Fig. 5 shows a perspective view of a preferred embodiment of the massage device 40 according to the invention. The massage device 40 has a massage part or a vibrating body 42, which is connected to a body with reference to FIG 1 to 4 described plug element 1 is connected. The cable 4 extends between the housing 2 of the plug-in element 1 and the vibrating body 42, the exit of the cable 4 from the housing 2 or from the vibrating body 42 being liquid-resistant. This can be done by appropriate seals or by the cable 4 having a common sheath with the respectively adjacent areas of the housing 2 or of the vibrating body 42. The ends of the cable 4 can also be glued to the housing 2 and the vibrating body 42, the adhesive providing the sealing effect in the outlet regions of the cable 4.

The vibrating body 42 has a vibration generating device and an energy store, which are functionally coupled or electrically connected to one another, as is generally known to the person skilled in the art. The vibration generating device and the energy store can be permanently contained in the vibrating body 42, e.g. B. encapsulated by the vibrating body 42 or poured into this. However, the vibration generating device and the energy store can also be designed to be removable from the vibration body 42. For this purpose, they are to be stored in a receptacle which can be inserted into and removed from a corresponding opening in the vibrating body 42. It is important to ensure a suitable seal between the receptacle and the vibrating body 42. The vibrations generated by the vibration generating device are transmitted to the receptacle and from there to the vibrating body.

The vibration generating device comprises, for example, an electric motor with an imbalance seated eccentrically on a shaft, which vibrates and vibrates the vibrating body 42 in response to signals from the control device 20. The energy store is preferably a rechargeable energy store, such as an accumulator.

In the embodiment according to the invention, it is now sufficient if the vibrating body 42 only receives the vibration generating device and the energy store. The remaining components, namely the control device 20, the data communication device 18, the circuit board antenna 12 and the charging electrodes 6 are arranged in the plug element 1. Since fewer components are to be arranged in the vibrating body 42, its shape can be designed more freely and flexibly and can be adapted to the needs of the users. In addition, a more cost-effective production results from the fact that the components to be arranged on a printed circuit board are arranged on a common printed circuit board 12 which is accommodated in a protected manner in the housing 2.

It is understood that the Fig. 5 represents the massage device 40 purely by way of example and the size ratio between the vibrating body 42 and the plug-in element 1 is not necessarily to scale. The length of the cable 4 can be made shorter or longer, depending on the design of the vibrating body, which depends in particular on whether or not the vibrating body 42 is completely accommodated in the user's body during use.

The shape of the vibrating body 42 can be designed very differently in order to be able to respond to the wishes of the customers for sex toys in as many different ways as possible. Examples of such shapes are conventional female vibrator shapes in different lengths and thicknesses, with or without a clitoral stimulator attached to the side, smaller vibration attachments, ring-like attachments, pair vibrators, male vibrators, penis ring attachments, anal attachments, love balls and the like. The vibrating body can also be designed as a shock wave vibrator. Basically, the plug-in element 1 can be used with any type of vibrator.

With the object according to the invention, a plug-in element for a remotely controllable massage device and such a massage device are provided, which are inexpensive to manufacture, have a reliable liquid-resistant function and are easy to charge the energy stores and enable flexible control using current wireless data transmission technologies.
