Description

Technical area

The invention relates to a personal care device in which a sequence of movements of a first adjusting device and preferably the rotation of a brush and a second adjusting device can be set and stored by a user by means of an operating device.

State of the art

Some personal care devices with rotary actuators for a brush are already known in the art.

For example, describes the EP 1 744 654 B1 (Oberli Bruno ) a body care brush with a brush holder and an attachable brush. The brush holder has an adjustable along an attachable to a wall rail guide transition piece and an electric motor for driving the brush. Further, the brush holder includes an open-topped console for receiving batteries that feed the electric motor.

The DE 23 36 455 (Müller Hugo ) discloses a body brush device having an electrically driven rotating brush roller which is moveable up and down on a guide means. The guide means is formed as a guide bar which has a rack with which a gear connected to the motor for raising and lowering the brush roller is engaged. Furthermore, a manual control unit is provided for operating the body brush.

A disadvantage of the previously known personal care devices is that each position of a brush must be adjusted either manually or via a manual control unit.

Presentation of the invention

The object of the invention is to provide a body care device belonging to the technical field mentioned above, which allows a simple and comfortable setting of different brush positions.

The solution of the problem is defined by the features of claim 1. According to the invention, the personal care device comprises at least one rod attachable to a wall and a housing arranged linearly displaceably on the at least one rod. The housing comprises a holder for a brush and a first adjusting device for displacing the housing relative to the rod. Further the housing comprises at least one accumulator and at least one electric motor for driving the first adjusting device. Furthermore, the housing comprises a control device which can be actuated via a control device that is separate from the housing and in data communication with the control device. The control device is configured such that an individual sequence of control instructions for the adjustment device can be defined and stored by the user by means of the operating device.

As a result, a user can individually program a movement sequence. In addition, an operating device separate from the housing allows the most comfortable possible setting of the individual control instructions and thus the sequence of movements, since the user does not have to make settings themselves on the housing, but can do this comfortably on the control device.

The personal care device can be fixed in any room to a wall, but preferably the personal care device is designed for use in the bathroom, especially in a shower cubicle or above a bathtub. Accordingly, the at least one motor and the at least one accumulator are protected against splashing water introduced in the housing. In order to facilitate the simplest possible charging of the at least one accumulator, this is particularly preferably removable from the housing. Preferably, therefore, the housing has a protected against splashing water, lockable receptacle for the at least one accumulator.

Preferably, the inventive personal care device comprises only one rod, along which the housing is arranged displaceably. Alternatively, more than one rod, in particular two mutually parallel rods may be provided.

The at least one rod may have any cross-section, but this is preferably round or oval. Alternatively preferably, the cross section of the at least one rod can also be configured square or rectangular.

Particularly preferably, the rod is designed for vertical attachment to a wall. In a vertical attachment, a height adjustment of the holder for the brush can be achieved by the linear displacement of the housing relative to the rod.

The at least one rod has a length which is chosen such that an optimal use of the personal care device is possible. In particular, the rod should have a sufficient length so that the holder for the brush can be moved to a height that allows the treatment of the shoulder and neck of even tall people through the brush. Preferably, the length of the rod is chosen such that a first end of the rod is located near the bottom, so that the brush and the calf and foot area of a user can be treated.

The at least one rod can be fastened to a wall via corresponding holding devices. The holding devices have, for example, wall holders, which can be fastened to a wall by means of fastening means, such as screws, adhesive, suction cups, nails, dowels or the like, and have a receptacle for the at least one bar. Alternatively, the at least one rod can also be connected directly to the wall via a suitable fastening means. Particularly preferably, the at least one rod can be connected to the wall via two holding devices arranged at each of its ends.

The housing is slidably disposed on the at least one rod, that is, the housing has suitable means which allow movement of the housing along the at least one rod, such as sliding or roller bearings. Preferably, the housing has at least one passage opening or a recess into which the at least one rod can be inserted or carried. About the at least one passage opening or recess, a particularly advantageous guidance of the housing can be achieved on the at least one rod. More preferably, the housing is arranged against rotation on the at least one rod, ie that only a displacement of the housing along the longitudinal direction of the at least one rod, but no rotation of the housing about the longitudinal direction of the at least one rod is possible.

Preferably, the housing has a circumferential wall which protects the individual components contained therein from dirt and water.

The bracket has retaining means for releasably attaching a brush to the bracket. The holder is preferably designed as a cylinder, on which a cylindrical brush can be slipped or placed. Alternatively, the holder may also be designed for fastening a round brush via a corresponding receiving surface or a connecting element. The bracket has suitable fasteners to detachably attach the brush to the bracket.

The brush preferably has bristles with which a body part of a user can be brushed or massaged. The bristles are preferably made of a polymeric material. More preferably, the brush may also have at least one layer of a preferably porous foam. Alternatively, the brush can also have a textile surface with which a washing or care solution can be applied to the skin of a user.

The first adjusting device is designed such that a linear displacement of the housing in both directions along the at least one rod is possible. That that at a vertically arranged at least one rod, a displacement of the housing both down and up is possible. The first adjustment device has means to allow the linear displacement of the housing relative to the rod. These means are in particular wheels or rollers which roll on the surface of the at least one rod and thus allow a relative displacement of the housing relative to the at least one rod. The at least one electric motor is preferably connected via a transmission with the first adjusting device, so that a torque can be transmitted from the at least one electric motor to the first adjusting device. Preferably, the transmission has a cascade of gears.

The control device preferably has at least one microchip which enables electronic control of the at least one motor as well as a data connection with the operating device. More preferably, the control device comprises a memory module in which at least one individual sequence of control instructions can be stored. The memory module is preferably a non-volatile data memory, particularly preferably a flash memory.

A "control instruction" in the sense of the present application is an instruction that the first adjusting device moves the housing a certain distance in a direction along the at least one rod. Based on this control instruction, the control device controls the at least one electric motor in such a way that the corresponding instruction is converted.

The operating device is preferably present as a remote control, which enables a wireless data connection with the control device. The operating device accordingly has buttons or other input elements, which allow the setting of control instructions by a user. For example, the operating device can have arrow keys with which the first adjusting device can be moved in both directions along the at least one rod.

Alternatively, the use of a tablet computer with a corresponding application, which allows control of the control device via a wireless data communication, in particular via a W-LAN, may be provided. Accordingly, in this alternative embodiment, the controller is equipped with a corresponding receiver.

Preferably, the data connection between the operating device and the control device is designed as a radio link. A radio link has the advantage that the operating device does not have to be directed to the control device in order to allow a data connection, as would be the case, for example, with an infrared data connection. In addition, can be dispensed with an opening for a receiver in the housing, since the data transmission is not affected by a radio connection through the housing, i. the receiver may be protected from water as part of the control device may be disposed within the housing.

Appropriate data transmission protocols as well as radio frequencies are known to a person skilled in the art.

Preferably, the brush is rotatably mounted about a first axis on the holder. The brush is driven via the at least one electric motor or via a second electric motor. The control device and the operating device are further designed such that control instructions for the rotation of the brush can be set and stored.

The first axis is preferably arranged such that it is parallel to the at least one rod, i. to the direction of displacement of the housing on the at least one rod. Alternatively, however, the first axis can also be at an angle, in particular at a right angle to the at least one rod.

The direction of rotation of the brush about the first axis may preferably be changed by a user. More preferably, the rotational speed of the brush can be changed by the user.

Both the adjusting device and the brush can be driven by the same motor. The power transmission between the electric motor and the first adjusting device and the brush can be realized via corresponding gear. In order to enable an independent drive of the first adjusting device and the brush, at least one coupling is preferably provided with which at least the power transmission between the at least one electric motor and the first adjusting device can be switched.

More preferably, however, the rotation of the brush is driven by a second electric motor. This allows the simplest possible embodiment of the personal care device, as can be dispensed with complex gear and / or clutches.

Accordingly, in providing a rotatable brush, the control instructions also include instructions for turning on and off the rotation of the brush and its direction of rotation. If a variation of the rotational speed is provided, the control instructions may further comprise corresponding signals.

The operating device preferably has corresponding keys which allow the turning on and off of the rotation of the brush and the definition of the direction of rotation and possibly the rotational speed.

Preferably, the control unit is connected to at least one sensor which determines the current position of the housing between a first end and a second end of the at least one rod. This gives the control unit data on the position of the housing on the at least one rod. This allows the control unit to determine and store the position of the housing along the at least one bar when setting and storing a sequence of control commands, so that when later retrieving the control instructions, the housing can be moved to the same, stored position, regardless from which position of the housing the sequence is retrieved.

Particularly preferably, the sensor comprises a roller in contact with the at least one rod and a counting device for the number of revolutions of the roller. This allows a simply constructed, but very precise determination of the position of the housing between the first and the second end of the at least one rod. The count of the revolutions is preferably achieved via a magnet attached to the roller, the passage of which is counted by a corresponding magnetic sensor. Alternatively, the count of revolutions can also be made by a light barrier with which the passage of holes present in the roll or of reflectors can be counted. A person skilled in the art will understand that such a counting device can also be realized with a wheel instead of a roller.

Preferably, a second adjusting device is arranged between the housing and the holder, which allows a movement of the first axis of rotation of the holder relative to the housing. Particularly preferably, the second adjusting device is configured such that the axis of rotation of the holder from a first position, which is substantially parallel to the alignment with the longitudinal axis of the at least one rod, in a second position which is substantially at right angles to the longitudinal direction at least one pole stands, lets move. Particularly preferably, the second adjusting device allows the locking of the axis of rotation at different angles between the first position and the second position. The second adjusting device can be manually adjusted, for example, by a handle by the user, wherein the locking of the first axis of rotation can be realized at a certain angle on the tightening of a bolt. Alternatively, a plurality of latching positions, which correspond to different angular positions of the first axis of rotation, may be provided for a bolt.

Preferably, the second adjusting device is driven by the at least one electric motor. However, the drive of the second adjusting device is particularly preferably carried out by a third electric motor. The control device and the operating device are configured in both cases such that control instructions for the second adjusting device can be fixed and stored by a user via the operating device.

This allows the simplest possible operation of the personal care device by the user, since in addition to the displacement of the housing by the first adjustment and the rotational movement of the brush in addition, the movement of the holder can be controlled by the second adjusting device via the operating device. This allows for the setting and storage of the movement of the support in a sequence of control instructions, allowing for a high degree of customization and adjustment by a user of the movements of the individual components of the personal care device.

If the second adjusting device is driven by the same electric motor as the first adjusting device and / or the rotation of the brush, the transmission of forces from this electric motor to the second adjusting device takes place via a corresponding gear, wherein particularly preferably at least one shiftable clutch is arranged in this gear is that the transmission of forces from the engine to the second adjustment by the control means switchable on and can be coupled out.

In particular, however, the second adjusting device is preferably driven by a separate electric motor. This simplifies the structure of the personal care device, as can be dispensed with a complex transmission with clutch. In addition, an electric motor suitable for driving the second adjusting device can be used.

Preferably, the first adjustment device has at least two arranged on opposite sides of the rod, with this in contact and rotating in the opposite direction drive rollers whose axes of rotation are at right angles to the longitudinal axis of the at least one rod and which are driven by the at least one electric motor. Particularly preferred are the drive rollers made of rubber.

This allows a very simple embodiment of the first adjustment. The displacement of the housing along the at least one rod takes place in this preferred embodiment, the static friction between the at least two rollers and the at least one rod. This has the advantage that the movement of the housing upon the occurrence of a greater resistance to movement, for example by a body part of a user clamped between the housing and the rod, such. a finger or a hair strand, is automatically stopped. This increases the operational safety of the personal care device according to the invention,

The at least two rollers are mechanically connected via a transmission with the at least one electric motor, wherein between the at least two rollers, the transmission has no translation, so that they have the same rotational speed. Only a reversal of the direction of rotation is needed because the rollers on the opposite sides of the rod would otherwise work against each other. The transmission preferably has only gears and pinions.

Rubber has a particularly advantageous coefficient of static friction, in particular in wet conditions with respect to the at least one rod, so that a reliable displacement of the housing along the at least one rod can be guaranteed. The at least two rollers are particularly preferably made of soft rubber.

Alternatively, the at least two rollers can also consist of another suitable material, in particular of a polymer. The at least two rollers can be additionally pressed to increase the static friction by a spring force against the at least one rod.

Preferably, the control device and the operating device are configured such that a user can define and store any desired sequence of control instructions for the first adjusting device and preferably for the rotation of the brush and for the second adjusting device via the operating device and subsequently transfer this stored sequence by the user the operating device can be retrieved.

This allows a user to once set and save a sequence of control statements and retrieve them over and over again. Particularly preferably, the control device and the operating device are further configured such that a plurality of sequences of control instructions can be defined and stored separately retrievable. As a result, a personal care device according to the invention for various applications or different users can store individually defined sequences of control instructions. Particularly preferably, the operating device has a plurality of keys, which are provided with corresponding identifications, such as "1", "2", "3" etc. or "A", "B", "C" etc., and which by a user a fixed sequence of control instructions can be assigned.

The present invention further relates to a method for operating a personal care device according to the invention, wherein a user defines a sequence of control instructions for the first adjustment device and preferably for the rotation of the brush and for the second adjustment device by means of the operating device, wherein this sequence of control instructions is stored in the control device become.

As a result, a user can individually program a sequence of movements of the individual components of the personal care device.

Preferably, a stored sequence is subsequently retrieved by means of an assigned identification by a user via the operating device.

The identification may be determined by the user or alternatively automatically by the operating device and / or the control device. This determination is preferably made prior to the user determining the sequence of control instructions.

Preferably, prior to establishing a sequence of control instructions, a first initialization step is performed by the controller, wherein the housing is moved over the entire length of the at least one rod by the first adjustment device and a sensor mounted on the housing measures the length of the at least one rod and in the Control device stores.

By means of such a first initialization step, an arbitrarily long at least one rod can be used, since its length is measured before a sequence of control instructions is defined. Preferably, this step is carried out once after the personal care device has been mounted, with the length of the at least one bar measured by the sensor remaining stored.

Alternatively, in a second initialization step, the housing can be displaced up to a reference point located on the at least one rod. The reference point may be, for example, an end of the rod. As a result, a starting point is determined which allows the control device always to calculate the current position of the housing along the at least one rod relative to the reference point on the basis of the displacement distance determined by the sensor. As a result, the housing can very reliably approach an initial position on the at least one rod, from which a stored sequence of control instructions is executed. Such a second initialization step may be automatically performed, for example, after each start-up of the personal care device or before retrieving or establishing a sequence of control instructions.

Furthermore, the control device can store the position of the housing relative to the reference point even after completion of a stored sequence of control instructions, so that the control device already knows the position of the housing on the at least one rod at the next retrieval of a stored sequence of control instructions or before the next startup.

Alternatively, an initialization step may also be performed after each replacement or recharge of the accumulator. The "length" is preferably not an absolute value stored in a common length unit, but the measured length is rather dependent on the type of sensor used. For example, in the preferred sensor, in which the revolutions of a roller running on the at least one rod are counted, the number of revolutions for the departure of the entire length can be stored.

Preferably, the controller stops the retrieved sequence of movements when a sensor mounted on the housing with driven first adjusting device does not measure displacement of the housing relative to the rod.

This increases the security of a personal care device according to the invention, since, for example, in the case of a trapped body part of a user, all further movements of the individual components of the personal care device are interrupted, whereby no additional risk of injury to the user arises. In addition, as well as damage to the personal care device, which could be caused by an obstacle located in the direction of movement of the housing, can be avoided.

From the following detailed description and the totality of the claims, further advantageous embodiments and feature combinations of the invention result.

Basically, the same parts are provided with the same reference numerals in the figures.

Ways to carry out the invention

The FIG. 1 shows a perspective view of an embodiment of a personal care device according to the invention 1. The personal care device 1 comprises a rod 3, which on a wall 2, of which only a section is shown in the figure, attached. The attachment of the rod 3 to the wall 2 via a first holding device 13 and a second holding device 14. The first holding device is arranged at a first end 15 and the second holding device 14 at a second end 16 of the rod 3. The attachment of the holder devices 13, 14 on the wall via suitable fastening means (not shown), such as screws or dowels.

A housing 4 is arranged linearly movable on the rod 3. A first adjusting device (not shown in the figure) allows a movement of the housing 4 along the rod 3 optionally in the direction of the first end 15 or the second end 16. The housing 4 has a circumferential wall 17 and a receptacle 11 for a rechargeable battery ( not shown in the figure). The receptacle 11 is open at the top and is closed during use of the personal care device for protection against water and dirt with a sealable lid 12 sealed.

A holder 5 for an attachable thereto and rotatably mounted relative to this brush 7 is connected via an arm 10 and a second adjusting device 9 with the housing 4. By means of the second adjustment device 9, the first axis of rotation 6 can be moved relative to the longitudinal axis of the rod 3 about a second axis 18. As a result, different inclination angles between the first axis of rotation 6 and the longitudinal axis of the rod 3 can be set by a user.

The brush 7 is cylindrical in the embodiment shown and has along a portion of its longitudinal axis on a cylindrical opening into which the cylindrical holder 5 can be inserted. By suitable holding means (not shown), the brush 7 is detachably connected to the holder 5.

Furthermore, the personal care device comprises an operating device 20, which is in data communication with a control unit (not shown in the figure) in the housing 4. Via the operating device 20, a user can control the movement of the housing 4 along the rod 3, the rotation of the brush 7 and possibly the movement of the second adjusting device 9 and individually set and store a sequence of control instructions for each of these components.

The FIG. 2 shows a side view of the housing 4 of the personal care device 1 of the FIG. 1 , wherein the viewer facing side of the wall 17 has been omitted to allow an insight into the housing 4. In contrast to FIG. 1 no brush 7 is mounted on the holder 5 and the lid 12 on the receptacle 11 (not shown).

Within the holder 5, a second electric motor is arranged, which serves to drive the brush 7. A torque can be transmitted from the second electric motor to the brush 7 via a rotatable holder device 8, which has a driver 37 which can be brought into engagement with the brush 7. The second electric motor allows a change in the direction of rotation and preferably the rotational speed of the rotatable holding device 8 about the first axis 6. The driver 37 is formed as a groove into which a matching counterpart on the inside of the opening of the brush 7 can be inserted. Preferably, the driver 37 at least one Positive locking element with which the brush 7 can be detachably connected to the holding device 8.

About the support arm 10, the holder 5 is connected to the second adjusting device 9. Cables for the second electric motor are arranged in the holding arm 10. In the embodiment shown, the second adjusting device 9 is designed as a manually operated by a user mechanism. About a pin 29 can rotate about the second axis 18 and lock in a certain position. The bolt 29 can be pulled preferably only against the action of a spring force in an unlocked position, so that upon release of the bolt 29 this is always pulled into a locked position in which the second adjusting device 9 is locked, i. a movement of the same about the second axis 18 is prevented.

The first adjusting device 21 is driven by a first electric motor 22 and comprises three drive rollers 23, 24, 25 which rest on both sides of the rod 3. The first drive roller 23 is substantially opposite to the second drive roller 24, wherein the rod 3 between these two drive rollers 23, 24 is arranged. The third drive roller 25 is located on the same side of the rod 3 as the second drive roller 24 and substantially opposite a sensor roller 28. Via gears (see FIG. 3 ), a power transmission between the first electric motor 22 and the drive rollers 23, 24, 25 allows. The circumference of the three drive rollers 23, 24, 25 and the sensor roller 28 are made of rubber, wherein the distance between the first drive roller 23 and the second drive roller 24 and the third drive roller 25 and the sensor roller 28 is selected such that the rollers 23, 24 , 25, 28 pressurized on the surface of the rod 3 rest. Upon rotation of the drive rollers 23, 24, 25, a movement of the housing on the rod 3 can be achieved via the friction occurring between the drive rollers 23, 24, 25 and the rod 3.

On the housing 4, two wall rollers 26, 27 are further arranged, which on the wall 2 (not shown in this figure) can roll. This additionally supports the housing 4 and also prevents a grinding movement of the housing 4 on the wall.

In the housing, a control device 30 is further arranged, which via a corresponding receiver in data communication with the operating device 20 (not shown in this figure) is. Control instructions, which are set by a user on the operating device 20, are forwarded to the first electric motor 22 and the second electric motor via the control device. In the illustrated embodiment, the control commands include in particular the switching on and off and the direction of rotation of the first electric motor 22 and the second electric motor.

Via the sensor roller 28, the control device 30 can determine the position of the housing on the rod 3. After mounting the personal care device 1, a first initialization step may be performed by the controller 30, moving the housing 4 at least once over the entire length of the rod 3, counting the number of revolutions of the sensor roller 28 and storing it in the controller 30. Alternatively or additionally, prior to retrieving or establishing a sequence of control instructions, a second initialization step may be performed by the controller (30), with the housing 4 up to a reference point located on the at least one bar 3, e.g. one of the holding devices 13, 14, is moved, which serves for the control device 30 as a start position for determining the position of the housing 4 on the at least one rod 3. In operation, with each movement of the housing 4 relative to the rod 3, the revolutions of the sensor roller 28 are counted, the control device 30 calculating the current position of the housing 4 on the rod 3 based on the starting position, the number of revolutions and the direction of rotation of the first electric motor 22 can. The revolutions of the sensor roller are preferably counted by the number of passes of a magnet which is mounted at a position close to the lateral surface of the roller by a corresponding detector.

To power the first electric motor 22, the second electric motor and the control device 30, an accumulator 19 is inserted in the corresponding receptacle 11. By the cover 12, not shown in this figure, the receptacle 11 can be sealingly closed to the accumulator 19 before water and Protect dirt. To charge the accumulator 19, this can be taken from the receptacle 11 and charged with an external charger (not shown).

The FIG. 3 shows a side view of the housing 4 as in the FIG. 2 from the other side. Again, the wall 17 is not shown on the side of the viewer to allow an insight into the housing 4. In this illustration, a brush 7 is arranged on the holder 5 and the cover 12 is placed on the receptacle 11.

In this figure, the power transmission between the first electric motor 22 and the three drive rollers 23, 24, 25 can be seen. A pinion 31 of the first electric motor 22 engages a first gear 32. Due to the different number of teeth of the pinion 31 and the first gear 32, a reduction is formed, whereby the rotational speed of the first gear 32 is reduced relative to the rotational speed of the first electric motor 22. The first gear 32 is engaged with a second gear 33. The second gear 33 is connected to the first drive roller 23 via the rotation axis, whereby rotation of the second gear 33 allows rotation of the first drive roller 23. Further, the second gear 33 is engaged with a third gear 34. The third gear 34 is connected via the rotation axis with the second drive roller 24. Further, the first gear 32 is engaged with a fourth gear 35, which in turn is in mesh with a fifth gear 36. The fifth gear 36 is connected via the rotation axis with the third drive roller 25. The five gears 32, 33, 34, 35, 36 have the same number of teeth, i. There is no over or under reduction.
