Description

[Technical field]

[0001] The invention relates to a shape-changing stimulation device for physical stimulation comprising at least one rocking body having a bearing receiving unit, the at least one rocking bearing unit being arranged for supporting the at least one rocking body, the drive shaft being rotatably supported and designed to be driven about a rotation axis by a motor unit, the drive shaft having at least one rocking bearing unit connected in a torque-resistant manner to the drive shaft. [Background technology]

[0002] U.S. Patent No. 10,350,135 discloses a stimulation device having a curved drive shaft, the end of which has a sliding element disposed thereon that contacts a guide groove in a massage body of the stimulation device, thereby moving the massage body towards and away from the foot end of the stimulation device.

[0003] In this type of stimulation device, the disadvantage is that, due to the bending of the drive shaft, relatively large bending moments and relatively large radial forces act on the drive shaft bearing. Furthermore, due to the bending of the drive shaft, it is only possible to arrange the drive shaft bearing at a relatively large distance from the contact point of the sliding element and the guide groove. Therefore, for this reason too, the drive shaft bearing is exposed to considerable loads due to the resulting bending moments and the resulting radial forces.

[0004] In order to achieve a long service life of the stimulation device despite the relatively large bending moments and relatively large radial forces, the bearings of the drive shaft must be relatively large, i.e. in particular with a relatively large diameter and / or a relatively large width, which is in contradiction with the aim of designing such a stimulation device as user-friendly as possible so that it can be used appropriately as a stimulation device for physical massage and stimulation.

[0005] Moreover, this type of stimulation device allows for a shape change of the massage body in only one direction at one time or time interval, i.e. for example a movement of the massage body towards the foot end or away from the foot end. In this respect, known stimulation devices are often only able to perform one bending or one stretching movement at one time or time interval.

[0006] However, for an improved massage and stimulation experience, it may be preferable for the massage body to perform shape changes in different directions at one point in time or time interval, so that, for example, the lower part of the massage body moves toward the foot end (i.e., bends) while the upper part of the massage body moves away from the foot end (i.e., stretches) at the same point in time or in the same time interval. Summary of the Invention [Problem to be solved by the invention]

[0007] It is therefore an object of the present invention to provide a stimulation device which reduces or eliminates the drawbacks of existing solutions. A particular object of the present invention is to provide a stimulation device which has a long service life and at the same time is designed to be easy to handle. Furthermore, it is a particular object of the present invention to provide a stimulation device which allows shape changes in different directions at the same time or in the same time interval. In particular, it is an object of the present invention to provide a stimulation device which allows an improved stimulation effect to be achieved on and / or within the body. [Means for solving the problem]

[0008] The problem of the invention is solved by a shape-changing massage device for physical stimulation, in particular for sexual stimulation, according to claim 1. The stimulation device is designed in particular for insertion into a body orifice, for example the vagina. Preferably, the stimulation device is designed as a vibrator or a dildo.

[0009] In particular, the object of the present invention is achieved by a shape-change stimulating device as described at the beginning, in which at least one oscillating bearing unit of the shape-change stimulating device defines an inclined axis inclined at an inclination angle to the axis of rotation, and the at least one oscillating bearing unit is designed to oscillately support the oscillating body relative to the drive shaft via at least one bearing receiving unit.

[0010] The stimulator extends longitudinally along the axis of rotation of the drive shaft. In particular, the stimulator preferably extends longitudinally between a hand unit and a head unit of the stimulator. The hand unit is designed to hold the stimulator. The head unit is designed in particular for massaging the body.

[0011] Typically, such a stimulation device according to the invention may have a deformable outer jacket. In particular, such an outer jacket defines the device interior, which may be sealed water-tight and / or air-tight against the surrounding environment. For example, the outer jacket may be made of an elastic material, such as silicone. Preferably, the outer jacket surrounds a rotatably supported drive shaft and / or a motor unit and / or at least one rocking bearing unit and / or at least one rocking body for use in the stimulation device.

[0012] The shape-change stimulation device according to the invention has a rotatably supported drive shaft, which is designed to be driven about a rotation axis by a motor unit. For this purpose, the drive shaft can be torque-resistantly connected to the motor unit in order to transmit the rotational movement of the motor unit to the drive shaft. It may be preferable to arrange a transmission between the motor unit and the drive shaft, which mechanically couples the motor unit and the drive shaft, in order to apply a desired rotation speed and / or a desired torque to the drive shaft. The motor unit is in particular an electric motor, which can be supplied with power by a power supply unit, such as a battery, an accumulator and / or a low-voltage network.

[0013] Typically, the hand unit of the stimulation device comprises a motor unit and a power supply unit for supplying the motor unit with the power required for operation. In particular, it can be provided that a transmission is arranged in the hand unit, which transmits the rotation speed and / or torque of the motor unit to the drive shaft with a corresponding speed increase or decrease ratio. In particular, it should be understood that the drive shaft is rotatably supported in a rotational direction about the rotation axis of the drive shaft relative to the hand unit. Furthermore, the drive shaft is arranged in a fixed manner, preferably relative to the hand unit, in the longitudinal direction of the rotation axis.

[0014] In particular, one or more of the rockers may be located in a head unit of the stimulator. It is particularly contemplated that a drive shaft extends from the motor unit to the head unit.

[0015] The drive shaft has at least one rocking bearing unit connected to it in a torque-resistant manner. Preferably, the at least one rocking bearing unit is connected to the drive shaft in a form-locking and / or force-locking and / or material-locking manner. In particular, the rocking bearing unit is preferably connected to the drive shaft in a fixed manner in the longitudinal direction of the rotation axis. Preferably, the at least one rocking bearing unit is connected to the drive shaft in a form-locking and / or force-locking and / or material-locking manner in the longitudinal direction. Particularly preferably, the drive shaft and the at least one rocking bearing unit are formed integrally. In particular, it may be preferred that the drive shaft and / or the at least one rocking bearing unit are designed as a cast part, in particular as an injection-molded part.

[0016] It is particularly provided that the at least one rocking bearing unit has a corresponding shaft receiving portion, which is designed for connection to the shaft. In particular, it may be preferred that the shaft receiving portion of the at least one rocking bearing unit and the drive shaft are connected in a material- and / or form- and / or force-locking manner.

[0017] Preferably, the drive shaft and / or the at least one rocking bearing unit are made of steel and / or plastic. It may be preferred if the drive shaft consists of steel and the at least one rocking bearing unit is made of plastic or vice versa. Alternatively, it may be preferred that the drive shaft and the at least one rocking bearing unit are made of the same material. Furthermore, it may be preferred that the drive shaft and / or the at least one rocking bearing unit are coated. In particular, the at least one rocking bearing unit is made of or coated with a material with a low coefficient of friction. Materials with a low coefficient of friction suitable for the sliding bearing are, for example, sliding bearings made of PTFE composites, POM composites or bronze-based alloys, for example solid bronze, sintered bronze or rolled bronze. The at least one rocking bearing unit can also be made of a fiber composite, for example polyester fibers and / or glass fibers, embedded in a matrix of, for example, epoxy resin.

[0018] The rocking bearing units are preferably arranged spaced apart from one another in the longitudinal direction of the drive shaft or the rotation axis of the drive shaft. Preferably, the rocking bearing units are arranged at equal intervals in the longitudinal direction.

[0019] Furthermore, the shape-change stimulation device has at least one rocker body with at least one bearing accommodation unit. Preferably, at least one bearing accommodation unit is arranged on the rocker body. Preferably, the at least one bearing accommodation unit is connected to the rocker body in a torque-resistant manner. Additionally or alternatively, it may be preferred that the at least one bearing accommodation unit is fixedly connected to the rocker body in at least one translation direction. In particular, the at least one bearing accommodation unit is connected to the rocker body in a form-locking and / or force-locking and / or material-locking manner. Preferably, the at least one bearing accommodation unit and the rocker body are formed integrally. In particular, it may be preferred that the rocker body and / or the at least one bearing accommodation unit are designed as a cast part, in particular as an injection-molded part.

[0020] Preferably, at least one rocking bearing body and / or at least one bearing receiving unit are made of steel and / or plastic. It may be preferred that at least one rocking bearing body is made of steel and at least one bearing receiving unit is made of plastic or vice versa. Alternatively, if several bearing receiving parts are arranged, it may be preferred that these are made of the same material. Furthermore, it may be preferred that at least one bearing receiving unit is coated. In particular, at least one bearing receiving unit is made of or coated with a material with a low coefficient of friction. Materials with a low coefficient of friction suitable for sliding bearings are, for example, sliding bearings made of PTFE composites, POM composites or bronze-based alloys, for example solid bronze, sintered bronze or rolled bronze. At least one bearing receiving unit can also be made of a fiber composite material, for example polyester fibers and / or glass fibers, embedded in a matrix made of, for example, epoxy resin.

[0021] It may be preferred that the shape-change stimulator has a plurality of rockers. In particular, the shape-change stimulator has two or three rockers. The rockers are arranged spaced apart from one another in the longitudinal direction of the drive shaft or the rotation axis of the drive shaft. In particular, the rockers are arranged equidistant from one another in the longitudinal direction.

[0022] At least one rocking bearing unit is arranged in at least one bearing receiving unit for supporting at least one rocking body. In particular, the bearing unit of the rocking body is assigned to the rocking bearing unit. Preferably, the rocking body is assigned to the rocking bearing unit. Furthermore, it may be preferable for more than one rocking bearing unit to be assigned to the rocking body. Preferably, the at least one rocking bearing unit is in point, line or area contact with the at least one bearing receiving unit. In particular, the at least one rocking bearing unit and the at least one bearing receiving unit are designed as sliding bearings. If the drive shaft is driven by the motor unit, the at least one rocking bearing unit preferably slides relative to the at least one bearing receiving unit.

[0023] Preferably, at least one rocking bearing unit and at least one bearing receiving unit are designed as axial and / or radial plain bearings. If at least one rocking bearing unit and at least one bearing receiving unit are designed as axial bearings, at least one bearing receiving unit has a circumferential projection or is designed as a protuberance. In particular, at least one bearing receiving unit is designed as an axial bearing as a flanged bush. At least one rocking bearing unit is designed as an axial bearing, in particular in a plate- or ring-shaped manner. As an axial bearing, the projection of the at least one bearing receiving unit is in sliding contact with the at least one rocking bearing unit designed in a plate- or ring-shaped manner. If at least one rocking bearing unit and at least one bearing receiving unit are designed as radial bearings, at least one bearing receiving unit and at least one rocking bearing unit are preferably designed in a cylindrical shape. As a radial bearing, at least one bearing receiving unit designed in a cylindrical shape and at least one rocking bearing unit designed in a cylindrical shape are in sliding contact.

[0024] At least one rocking bearing unit defines an inclined axis inclined by an inclination angle with respect to the rotation axis of the drive shaft. Preferably, the inclined axis is oriented so as to intersect the rotation axis. In particular, in the case of a plurality of rocking bearing units, it is preferred that the respectively defined inclined axis intersects the rotation axis. In the case of a plurality of rocking bearing units, it may be preferred that the inclination angles of the inclined axes are different from one another, at least partially different from one another. In particular, in the case of a plurality of rocking bearing units, it is preferred that the inclination angles of the inclined axes are identical.

[0025] The tilt angle of the tilt axis is the angle between the axis of rotation and the tilt axis, in particular when the tilt axis crosses the axis of rotation or when the tilt axis crosses the axis of rotation after translation. Preferably, the tilt angle is at least 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 60°, 75° or 90°. It is further preferred that the tilt angle is at most 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, 60°, 75° or 90°.

[0026] The tilt axes of two adjacently arranged rocking bearing units preferably extend so that they do not intersect with each other. Two adjacently arranged rocking bearing units may preferably be arranged such that the tilt axes of the rocking bearing units are oriented such that they intersect, in particular at an angle that corresponds to the sum of the tilt angles of the two tilt axes. It may further be preferred that two or more tilt axes extend parallel to each other. In particular, the rocking bearing units are arranged such that the respective tilt axes extend offset by a rotation difference angle about the rotation axis. That is to say, the rotation difference angle is the angle between the tilt axes of two longitudinally arranged adjacent rocking bearing units. In so far as this is concerned, the rotation difference angle refers to the angle when the tilt axis of a rocker is rotated by this angle about the rotation axis with respect to the tilt axis of the adjacently arranged rocker.

[0027] Preferably, in a shape-change stimulation device having two rocking bodies, the tilt axis of one or more rocking bearing units assigned to one of the two rocking bodies is oriented offset relative to the tilt axis of one or more rocking bearing units assigned to the other of the two rocking bodies by a rotational difference angle of at least 45°, 60°, 90°, 120°, 135°, 180°, 225°, 270° or 315° in the direction of rotation of the drive shaft about the rotation axis, and by a rotational difference angle of at most 45°, 60°, 90°, 120°, 135°, 180°, 225°, 270° or 315°.

[0028] At least one rocking bearing unit is designed to rockably support at least one rocker via at least one bearing receiving unit with respect to the drive shaft. The rocker is supported at an inclination angle with respect to the rotation axis depending on the inclination angle defined by the rocking bearing unit. The direction of inclination of each rocker varies depending on the rotation angle of the respective rocking bearing unit.

[0029] The at least one rocker is preferably fixed in the circumferential direction about the rotation axis relative to the drive shaft. In particular, for the rocking support of the at least one rocker relative to the drive shaft, it is provided that the at least one rocker is arranged stationary in the direction of rotation of the drive shaft. Furthermore, it is preferably provided that the rocking supported at least one rocker is arranged stationary relative to the drive shaft in the longitudinal direction of the rotation axis.

[0030] However, it is preferred that at least one rocker supported rocker performs a rocking movement during operation of the stimulation device depending on the rotation angle around the rotation axis of the drive shaft which rotates during operation. In particular, the rocking movement of the at least one rocker is defined in such a way that the at least one rocker is arranged coaxially with the tilt axis of the at least one rocker bearing unit. In particular, it should be understood that the at least one rocker is designed exclusively to perform a rocking movement and not to perform a rotation movement around a rotation axis. The rocking movement of the rocker results in a shape change of the stimulation device. The arrangement of several rockers particularly advantageously results in a shape change of the stimulation device in different directions at the same time or in the same time interval.

[0031] That is to say, the at least one rocker is arranged with respect to the drive shaft such that the rocker does not perform a rotational movement about the axis of rotation, but the at least one rocker is arranged with respect to the drive shaft such that during operation of the stimulation device the at least one rocker performs a rocking movement with respect to the drive shaft or the at least one rocking bearing unit.

[0032] During operation, the rotating drive shaft brings about a rotation of the at least one rocking bearing unit and thus a rotation of the tilted axis defined by the respective rocking bearing unit. When the drive shaft rotates 360° about the rotation axis, the tilted axis describes a conical flank that is in particular aligned rotationally symmetrically with respect to the rotation axis. The invention is therefore characterized by at least one rocking body that is supported by at least one rocking bearing unit at an inclination angle with respect to the rotation axis. It is preferably provided that the inclination angle is constant regardless of the rotation angle of the at least one rocking bearing unit. In particular, it is provided that the inclined axis of the at least one rocking bearing unit that rotates about the drive shaft defines a conical flank.

[0033] The stimulation device according to the invention thus reduces, if not eliminates, the disadvantages of existing solutions. In particular, the design of the stimulation device according to the invention allows a particularly space-saving and wear-free support for carrying out a rocking movement, i.e. a shape change, of the stimulation device at the same point or at the same time interval in several directions. In particular, the wear-free support of the rocker on the drive shaft results in a comparatively long service life of the stimulation device. Furthermore, the above-mentioned arrangement of the rocker on the drive shaft results in the bearing being exposed to less load, which on the one hand also has a positive effect on the service life and on the other hand allows for a particularly easy-to-handle design of the stimulation device.

[0034] According to a preferred embodiment of the shape-change stimulator, it is contemplated that the drive shaft is a straight drive shaft. A straight drive shaft in particular does not have a curvature. In particular, a straight drive shaft has zero curvature. In particular, the manufacture and assembly of a straight drive shaft is simpler and cheaper than a curved drive shaft. Furthermore, such a straight drive shaft may have the advantage that bending loads are minimal.

[0035] Additionally or alternatively, in this preferred embodiment of the shape-changing stimulator, it is contemplated that the drive shaft has a polygonal shaft cross section. A polygonal shaft cross section is in particular a multi-sided cross section. For example, a polygonal shaft cross section is a triangular, square, pentagonal, hexagonal, etc. cross section. It may be preferred that the shaft cross section is designed as a star-shaped or gear-shaped cross section.

[0036] Preferably, at least one rocking bearing unit is designed to form-fittingly accommodate a drive shaft with a polygonal shaft cross-section. Preferably, the shaft accommodation is designed as a polygonal accommodation cross-section. In particular, the polygonal accommodation cross-section is a multi-sided cross-section. For example, polygonal accommodation cross-sections are triangular, quadrangular, pentagonal, hexagonal, etc. cross-sections. It may be preferable for the accommodation cross-section to be designed as a star-shaped or gear-shaped cross-section.

[0037] This allows a form-locking connection between the drive shaft and the motor unit, and furthermore the drive shaft can be connected in a particularly simple manner to the rocking bearing unit in a non-rotatable manner, as a result of which torques can be transmitted particularly well.

[0038] In another preferred development of the shape-change stimulation device, the rocking bearing unit has a rocking bearing surface arranged at an angle to the axis of rotation, in particular the rocking bearing surface being designed for rocking support of the rocker on the drive shaft via at least one bearing receiving unit.

[0039] The oscillating bearing surface inclined to the rotation axis intersects the rotation axis, in particular at an inclination angle greater than 0° and smaller than 90°. Preferably, the oscillating bearing surface inclined to the rotation axis does not extend parallel to the rotation axis. Furthermore, it is preferred that the oscillating bearing surface inclined to the rotation axis does not intersect the rotation axis perpendicularly. In particular, the oscillating bearing surface is arranged inclined to the rotation axis by the inclination angle.

[0040] It may be preferred that the oscillating support surface comprises one or more surface sections without curvature and one or more surface sections with curvature. Preferably, the one or more surface sections without curvature extend perpendicular to the tilt axis. It is further preferred that the one or more surface sections with curvature extend parallel to the tilt axis, in particular coaxially.

[0041] Furthermore, in a preferred development of the shape-change stimulation device, it is provided that the oscillating bearing surface has a cylindrical side-shaped oscillating bearing surface that extends coaxially with the tilt axis. Additionally or alternatively, in this preferred development of the shape-change stimulation device, the oscillating bearing surface has a plate-shaped oscillating bearing surface that extends perpendicular to the tilt axis.

[0042] Preferably, the cylindrical flank-shaped rocking bearing surface is a surface which corresponds to a flank of a cylinder or corresponds to at least a part of a flank of a cylinder.

In particular, the plate-shaped rocking bearing surface is designed to be circular. Preferably, the plate-shaped rocking bearing surface is an end surface of a cylinder or corresponds to at least a part of an end surface of a cylinder. The plate-shaped rocking bearing surface is preferably a disk-shaped bearing surface.

[0043] In particular, it is preferred that the cylindrical side-shaped rocking bearing surface extends from the plate-shaped rocking bearing surface. Preferably, the cylindrical side-shaped rocking bearing surface extends perpendicular to the plate-shaped rocking bearing surface. It is preferred that the rocking bearing surface is formed by alternating cylindrical side-shaped rocking bearing surfaces and plate-shaped rocking bearing surfaces. In particular, it may be preferred that the rocking bearing surface has a plurality of cylindrical side-shaped rocking bearing surfaces and / or a plurality of plate-shaped rocking bearing surfaces.

[0044] It is preferable that the rocking bearing unit has a plurality of cylindrical flank-shaped rocking bearing surfaces, and in this case, it may be preferable that the plurality of cylindrical flank-shaped rocking bearing surfaces are arranged at a distance from each other.

[0045] It may further be preferred that the rocking bearing unit has a plurality of plate-shaped rocking bearing surfaces. In particular, it may be preferred in this case that the plurality of plate-shaped rocking bearing surfaces are arranged at a distance from one another. In a preferred development of the stimulation device, the rocking bearing unit can have two plate-shaped rocking bearing surfaces facing one another. It may further be preferred that the rocking bearing unit additionally or alternatively has two plate-shaped rocking bearing surfaces facing away from one another.

[0046] According to another preferred embodiment of the shape-change stimulation device, the rocking bearing unit has a rocking bearing adapter with a mounting receptacle, and the rocking bearing unit is connected to the drive shaft in a torque-resistant manner via the mounting receptacle.

[0047] Preferably, the rocking bearing adapter is positively and / or force- and / or materially connected to the drive shaft. In particular, it is preferred that the rocking bearing adapter is fixedly connected to the drive shaft in the longitudinal direction of the rotation axis. Preferably, the rocking bearing adapter is positively and / or force- and / or materially connected to the drive shaft in the longitudinal direction. It is particularly preferred that the drive shaft and the rocking bearing adapter are formed in one piece. In particular, it may be preferred that the drive shaft and / or the rocking bearing adapter are designed as a cast part, in particular as an injection-molded part.

[0048] In particular, it is provided that the rocker bearing adapter has a corresponding shaft receiving portion. In particular, it is provided that the shaft receiving portion corresponds to the mounting receiving portion.

[0049] The rocking bearing adapter allows a particularly simple and fast assembly of the shape-changing stimulation device, in particular by exchanging the rocking bearing adapter the tilt angle and thus the degree of shape change of the stimulation device can be adjusted as required.

[0050] Furthermore, in a preferred embodiment of the shape-changing stimulator, it is provided that the mounting housing extends coaxially with the axis of rotation, which allows a particularly favorable power transmission to occur. In particular, such an arrangement allows the bending moments acting on the drive shaft to be minimized. Particularly advantageously, this coaxial arrangement of the rocking bearing adapter allows for a compact form of the stimulator.

[0051] According to a further preferred development of the shape-change stimulation device, the mounting receptacle is a through-opening which extends through the rocking bearing adapter along the axis of rotation.

[0052] According to a further preferred development of the shape-change stimulation device, the through opening has a polygonal opening cross section.

[0053] Preferably, in this development it is provided that the opening cross-section corresponds to a polygonal shaft cross-section.

[0054] A polygonal opening cross section is in particular a multi-sided cross section, for example a triangular, quadrangular, pentagonal, hexagonal, etc. cross section. It may be preferred that the opening cross section is designed as a star-shaped or gear-shaped cross section.

[0055] Preferably, at least one rocking bearing unit is designed to form-fittingly accommodate a drive shaft with a polygonal shaft cross-section.

For example, polygonal accommodation cross-sections are triangular, quadrangular, pentagonal, hexagonal, etc. cross-sections. It may be preferable for the accommodation cross-section to be designed as a star-shaped or gear-shaped cross-section.

[0056] Furthermore, in a preferred embodiment of the shape-change stimulator, the rocking bearing adapter has a protrusion designed to support the bearing bush in the extension direction of the tilt axis.

[0057] Furthermore, in a preferred embodiment of the shape-changing stimulator, it is provided that the rocking bearing unit has a bearing bush surrounding the rocking bearing adapter on the circumferential side, preferably the bearing bush having a rocking bearing surface. This particularly advantageously allows for a simple and quick replacement of wear parts such as the bearing bush. In particular, this solution makes it possible that it is not necessary to replace the entire stimulator after the bearing bush has worn out, as is the case with stimulators according to the prior art.

[0058] According to another development of the shape-changing stimulator, the bearing bush has nylon as a material. In particular, it is provided that the bearing bush consists of nylon. Bearing bushes containing or consisting of nylon have particularly advantageous bearing and sliding properties. Nylon minimizes wear, thereby increasing the service life of such a stimulator.

[0059] According to a further preferred embodiment of the shape change stimulator, the bearing bush is designed as a plain bearing bush. Plain bearing bushes have the advantage of being more load-bearing and quieter than rolling bearings. Furthermore, the use of plain bearing bushes allows for the compensation of alignment errors and damps vibrations. In particular, plain bearing bushes allow for a more compact design than rolling bearings.

[0060] Furthermore, in a preferred development of the shape-change stimulation device, it is provided that the bearing bush has one or more bearing bush surface sections.

[Figure 6c] FIG. 6 is a schematic three-dimensional detailed view of a preferred embodiment of the stimulation device shown in FIG. 5. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0073] Figures 1a-c show schematic cross-sectional views of a preferred embodiment of a shape-changing stimulator 1 for body massage. The stimulator extends in the longitudinal direction of the drive shaft 10 or the axis of rotation D of the drive shaft 10 between a hand unit 70 and a head unit 80. In operation, the hand unit 70 is used to hold the stimulator 1 and the head unit 80 can be placed against the body for body massage.

[0074] The shape-change stimulator 1 comprises a drive shaft 10 rotatably supported about a rotation axis D, the drive shaft being mechanically coupled to and extending straight from a motor unit 20. The motor unit 20 drives the drive shaft 10 in one rotational direction about the rotation axis D with a desired number of rotations and a desired torque. Preferably, the number of rotations and the torque that the motor unit 20 can provide to drive the drive shaft 10 can also be varied during operation of the shape-change stimulator 1.

[0075] The drive shaft 10 has two rocking bearing units 40 connected to it in a torque-resistant manner. It can be seen that the rocking bearing units 40 are arranged at a distance from one another and that the drive shaft 10 extends longitudinally from the motor unit 20 along the rotation axis D to one of the two rocking bearing units 40. The other of the two rocking bearing units 40 is arranged between the motor unit 20 and this rocking bearing unit 40.

[0076] The two rocking bearing units 40 shown in Figures 1a to 1c each have a plate-shaped rocking bearing surface 42b which extends at an incline with respect to the axis of rotation D. These inclined plate-shaped rocking bearing surfaces 42b each define an inclination axis N which extends perpendicularly to the respective plate-shaped rocking bearing surface 42b and intersects with the axis of rotation D. It can be seen that the two inclination axes N extend offset with a rotational angle difference of 180° around the axis of rotation D.

[0077] A preferred embodiment of the shape-changing stimulation device 1 shown in Fig. 1a to Fig. 1c comprises two rocking bodies 30, each of which has a bearing receiving unit 50, which is supported by one of two rocking bearing units 40 for supporting the respective rocking bodies 30. Of the two rocking bodies 30, one rocking body 30 arranged facing the hand unit 70 in the longitudinal direction forms the head unit of the stimulation device 1. Of the two rocking bodies 30, the other rocking body 30 arranged between the hand unit 70 and the rocking body designed as the head unit in the longitudinal direction is designed as an intermediate body of the stimulation device 1.

[0078] Figures 1a to 1c show the drive shaft 10 of the stimulation device 1 at different angles of rotation. In Figure 1a, the drive shaft is for example at a rotation angle of 0°. In this position, the intermediate body is tilted to the left and the rocker forming the head unit is tilted to the right. Figure 1b shows the drive shaft at a rotation angle of 90°. In this position, the intermediate body is tilted forward (out of the plane of the paper) and the rocker forming the head unit is tilted backward (into the plane of the paper). Figure 1c finally shows the drive shaft at a rotation angle of 180°. In this position, the intermediate body is tilted to the right and the rocker forming the head unit is tilted to the left.

[0079] In this case, it should be understood that the rocker does not perform a rotational movement about the rotation axis while the drive shaft rotates about the rotation axis, but rather, the rocker only performs a rocking movement according to the rotation angle of the drive shaft, and is intended to be fixedly disposed in the rotation direction of the drive shaft.

[0080] It can be seen that in the rocker forming the head unit, the drive shaft 10 extends into the rocker but does not penetrate through it. That is, the rocker 30 forming the head unit has a rocker recess that extends from the first end face of the rocker 30 into the rocker 30. Thus, the drive shaft 10 extends partially into the rocker recess together with the rocker bearing unit 40.

[0081] The rocker 30 designed as an intermediate body is designed so that the drive shaft 10 extends through the rocker. That is, the rocker 30 designed as an intermediate body has a rocker through-opening. The rocker through-opening extends between the first end face and the second end face of the rocker. It is intended that the drive shaft extends through the rocker through-opening.

[0082] A support element 60 is arranged between the rocker forming the head unit and the rocker forming the intermediate body. Furthermore, a support element 60 is arranged between the rocker forming the intermediate body and the hand unit 70. Thus, one support element 60 supports the rocker 30 forming the head unit at its first end face and at its second end face relative to the rocker 30 forming the intermediate body. The other support element 60 supports the rocker forming the intermediate body at its first end face relative to the hand unit 70. Thus, the rocker is supported on the rocker bearing unit 40 in cooperation with the support element.

[0083] For this purpose, the support element 60 is designed to be deformable so as to follow the rocking movement of the rocker 30. To improve the deformability, the support element has a stepped outer jacket. The stepped outer jacket has a number of sections, each of which includes a cylindrical sidewall shaped outer jacket. It is preferably intended that the support element and the rocker are arranged stationary in the direction of rotation of the drive shaft.

[0084] Figures 2 to 5 each show a schematic cross-sectional view of another preferred embodiment of the stimulation device 1. The embodiment of the stimulation device 1 shown in Figures 2 to 5 is similar to the previously described embodiment of the stimulation device 1 shown in Figures 1a to 1c. The embodiment of the stimulation device 1 shown in Figures 2 to 5 differs substantially from the embodiment of the stimulation device 1 shown in Figure 1 in terms of the configuration of the at least one rocking bearing unit 40 and the at least one bearing receiving unit 50.

[0085] In FIG. 2, an embodiment of the stimulation device 1 is shown, in which at least one rocking bearing unit 40 has three rocking bearing surfaces 42a in the form of cylindrical side surfaces. Furthermore, it is envisaged that at least one rocking bearing unit 40 has four plate-like rocking bearing surfaces 42b, two of which face each other and two of which face away from each other. The bearing receiving unit 50 has three corresponding bearing receiving surface sections 50b, 50c, 50d in the form of cylindrical side surfaces extending coaxially with the tilt axis N. Thereby, the rocker is fixed radially with respect to the tilt axis N. Furthermore, the bearing receiving unit 50 has bearing receiving surface sections extending perpendicular to the tilt axis N, which are in sliding contact with the corresponding rocking bearing surfaces 42b for rocking support of the rocker. Thereby, the rocker is fixed along the tilt axis N.

[0086] In FIG. 3, an embodiment of the stimulation device 1 is shown in which at least one rocking bearing unit 40 has two cylindrical side-shaped rocking bearing surfaces 42a arranged at a distance from each other along the tilt axis N. Between the two cylindrical side-shaped rocking bearing surfaces 42a, two plate-shaped rocking bearing surfaces 42b facing opposite each other are provided. The bearing receiving unit 50 thus has two cylindrical side-shaped bearing receiving surface sections 50b, 50c extending parallel to the tilt axis N. This fixes the rocker radially relative to the tilt axis N. Furthermore, the bearing receiving unit 50 has bearing receiving surface sections extending perpendicular to the tilt axis N, which are in sliding contact with the corresponding rocking bearing surfaces 42b for rocking support of the rocker. This fixes the rocker along the tilt axis N.

[0087] In Fig. 4, an embodiment of the stimulation device 1 is shown, in which at least one rocking bearing unit 40 has a rocking bearing surface 42a in the form of a cylindrical side surface extending coaxially with the tilt axis N. Furthermore, at least one rocking bearing unit 40 has a protrusion 44 at its end, each of which forms a plate-shaped, in particular ring-shaped, rocking bearing surface 42b extending perpendicularly to the tilt axis N. The bearing receiving unit 50 has four corresponding bearing receiving surface sections 50b, 50c, 50d, 50e in the form of a cylindrical side surface extending coaxially with the tilt axis N and arranged at a distance from one another along the tilt axis N. Furthermore, the bearing receiving unit 50 has two bearing receiving surface sections extending perpendicularly to the tilt axis N, which are in sliding contact with the corresponding rocking bearing surface 42b for rocking support of the rocker.

[0088] In Fig. 5 an embodiment of the stimulation device 1 is shown which is substantially based on the embodiment of the stimulation device 1 shown in Fig. 4. Unlike the bearing receiving unit 50 shown in Fig. 4, the bearing receiving unit 50 shown in Fig. 5 has four bearing receiving surface sections in the form of cylindrical side surfaces, which are in sliding contact with the rocking bearing surface of the rocking bearing unit 40 to support the rocking body 30.

[0089] 6a-6c are schematic three-dimensional detailed views of a preferred embodiment of the stimulator 1 shown in FIG. 5, in particular the bearing accommodation unit 50 and the rocking bearing unit 40. The rocking bearing unit 40 has a rocking bearing adapter 41 with a mounting accommodation 43, via which the rocking bearing unit 40 is connected in a torque-resistant manner to the drive shaft 10. For this, the mounting accommodation 43 extends coaxially with the rotation axis D and has a through opening, which extends through the rocking bearing adapter 41 along the rotation axis D. To transmit the torque and the rotational movement of the drive shaft to the rocking bearing unit 40, the through opening has a polygonal opening cross-section. Correspondingly, the drive shaft 10 has a polygonal shaft cross-section corresponding to the opening cross-section. In the preferred embodiment shown here, the opening cross-section and the shaft cross-section are formed in a quadrangular shape.

[0090] In this preferred embodiment, it is further provided that the rocking bearing adapters 41 each have a projection 44 designed to support the bearing bush 45 in the extension direction of the tilt axis N. The bearing bush 45 surrounds the rocking bearing adapter 41 on the circumferential side and rests on the projection 44 of the rocking bearing adapter 41. In this embodiment, the bearing bush 45 has a cylindrical flank-shaped rocking bearing surface 42a, 42b, whereby the cylindrical flank-shaped rocking bearing surface 42a extends coaxially with the tilt axis N and the plate-shaped rocking bearing surface 42b extends perpendicularly to the tilt axis N. The bearing bush 45 forms a plain bearing together with the bearing receiving unit 50. This allows the drive shaft 10 together with the rocking bearing unit 40, which is non-rotatably mounted on the drive shaft 10, to rotate relative to the stationary arranged rocking body 30 in the rotation direction of the drive shaft 10, resulting in a rocking movement of the rocking body 30.
