The drawings described are only schematic and are non-limiting. In the drawings, the size of some of the elements may be exaggerated and not drawn on scale for illustrative purposes. The dimensions and the relative dimensions do not correspond to actual reductions to practice of the invention.

[0055] Furthermore, the terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a sequence, either temporally, spatially, in ranking or in any other manner. It is to be understood that the terms so used are interchangeable under appropriate circumstances and that the embodiments of the invention described herein are capable of operation in other sequences than described or illustrated herein.

[0056] It is to be noticed that the term comprising, used in the claims, should not be interpreted as being restricted to the means listed thereafter; it does not exclude other elements or steps. It is thus to be interpreted as specifying the presence of the stated features, integers, steps or components as referred to, but does not preclude the presence or addition of one or more other features, integers, steps or components, or groups thereof. Thus, the scope of the expression a device comprising means A and B should not be limited to devices consisting only of components A and B. It means that with respect to the present invention, the only relevant components of the device are A and B.

[0057] Reference throughout this specification to one embodiment or an embodiment means that a particular feature, structure or characteristic described in connection with the embodiment is included in at least one embodiment of the present invention. Thus, appearances of the phrases in one embodiment or in an embodiment in various places throughout this specification are not necessarily all referring to the same embodiment, but may. Furthermore, the particular features, structures or characteristics may be combined in any suitable manner, as would be apparent to one of ordinary skill in the art from this disclosure, in one or more embodiments.

[0058] Similarly it should be appreciated that in the description of exemplary embodiments of the invention, various features of the invention are sometimes grouped together in a single embodiment, figure, or description thereof for the purpose of streamlining the disclosure and aiding in the understanding of one or more of the various inventive aspects. This method of disclosure, however, is not to be interpreted as reflecting an intention that the claimed invention requires more features than are expressly recited in each claim. Rather, as the following claims reflect, inventive aspects lie in less than all features of a single foregoing disclosed embodiment. Thus, the claims following the detailed description are hereby expressly incorporated into this detailed description, with each claim standing on its own as a separate embodiment of this invention.

[0059] Furthermore, while some embodiments described herein include some but not other features included in other embodiments, combinations of features of different embodiments are meant to be within the scope of the invention, and form different embodiments, as would be understood by those in the art. For example, in the following claims, any of the claimed embodiments can be used in any combination.

[0060] In the description provided herein, numerous specific details are set forth. However, it is understood that embodiments of the invention may be practiced without these specific details. In other instances, well-known methods, structures and techniques have not been shown in detail in order not to obscure an understanding of this description.

[0061] The invention solves the problems as described above by providing a device having a massaging surface comprising a plurality of massaging elements or studs. The massaging elements are arranged as a first and a second set of massaging elements, both sets being distributed among each other. The first set of massaging elements is a fixed set of massaging elements. The second set of massaging elements is a fixed set of massaging elements. When moving the different sets of massaging elements relative to each other and applying the massaging surface a skin surface, the movement of the sets of massaging elements causes the skin to simultaneously pinch and stretch. Because of this simultaneous pinching and stretching of the skin, the massaging force is contained within the massaged area. With the forces onto the skin being localized, there is only the massaging load on the skin and no external net-load to stress the skin or interfere with the ease of handling the device. This makes the device extremely easy to handle while still achieving a good massaging effect on the skin. Also, because the massaging force is contained within the massaged area, power consumption is reduced leading to, for example, better battery life for handheld devices.

DETAILED EMBODIMENTS OF THE INVENTION ARE DESCRIBED BELOW

[0062] FIG. 1 illustrates an embodiment of the massaging device 100. Illustrated are a first 101, a second 102 and a third 103 massaging element. The first 101 and the third 103 massaging element are located on a first plate 104. The second massaging element 102 is located on a second plate 105. The first plate 104 is positioned on top of the second plate 105. The first plate 104 is moveable relative to the second plate 105. For example, the first plate 104 is moveable and the second plate 105 is fixed. Alternatively, the second plate 105 is moveable and the first plate 104 is fixed. Alternatively, the first plate 104 and the second plate 105 are moveable. The first plate 104 features a through-hole (not shown). The through-hole in the first plate 104 is positioned such that the second massaging element 102 penetrates the through-hole and protrudes the through-hole when the first plate 104 is positioned on top of the second plate 105.

[0063] Alternatively, the second massaging element 102 is located on a first plate 104. The first 101 and the third 103 massaging element are located on a second plate 105. The first plate 104 is positioned on top of the second plate 105. The first plate 104 is moveable relative to the second plate 105. For example, the first plate 104 is moveable and the second plate 105 is fixed. Alternatively, the second plate 105 is moveable and the first plate 104 is fixed. Alternatively, the first plate 104 and the second plate 105 are moveable. The first plate 104 features at least two through-holes (not shown). The through-holes in the first plate 104 are positioned such that the first 101 and the third 103 massaging element each penetrate a different through-hole and protrudes the through-holes when the first plate 104 is positioned on top of the second plate 105.

[0064] According to an embodiment of the invention, the massaging device comprises a piezoelectric element for moving a massaging element. For example, in FIG. 1, the second massaging element 102 may comprise a piezoelectric element. This allows the second massaging element 102 to be moved relative to the first 101 and third 103 massaging element. The piezoelectric element may be located underneath the second massaging element 102. The piezoelectric element may also be integrated in the second plate 105 at the location where the second massaging element is fixed to the second plate 105.

[0065] According to an embodiment of the invention, the massaging elements and the plate to which they are fixed are fabricated from a single piece of material. The massaging elements may be created by removing material from the material, for example through a milling process. Alternatively, the massaging elements and the plate may be fabricated via a single molding process. Alternatively, the massaging elements are mounted on a plate, for example bolted.

[0066] According to an embodiment of the invention, the massaging elements are fabricated from a material that has a substantial grip on skin when applied to it. For example, the massaging elements are fabricated from an elastic material such as rubber. The massaging elements may also be covered by such an elastic material. For example, the massaging elements are metal studs covered by an elastic material.

[0067] According to another embodiment of the invention, at least some of the massaging elements are fabricated from or covered with an abrasive material. The abrasive material may comprise abrasive particles fabricated from corundum (aluminum oxide), sodium bicarbonate, magnesium oxide, silicone carbide, or sapphire, or the like. These particles may be of a size ranging from about 50 to 300 grit, typically about 100 to 120 grit. In such an embodiment, the device may be used as an exfoliating (scrubbing), (micro)dermabrasion or grinding device to treat the skin, e.g. for callous removal. While in this description reference is made to massaging elements, in embodiments for removing one or more layers of the skin these massaging elements may be referred to as dermabrasion elements or skin layer removal elements.

[0068] According to an embodiment of the invention, the massaging device is a portable, handheld massaging device.

[0069] According to an embodiment of the invention, the massaging elements may be pillars or studs. The massaging elements may have any shape suitable for massaging the skin. For example, the massaging elements may be shaped as a cone, a dome, a pyramid, a cube, a torus, a cylinder.

[0070] According to an embodiment of the invention, the distance between adjacent massaging elements on a plate may be between 5 to 25 mm. In a particular embodiment, the distance between advancement massaging elements on the same plate is 10 mm.

[0071] FIG. 2 illustrates an embodiment of the massaging device 100. A first plate 104 and a second plate 105 are illustrated. The first plate 104 comprises a first set of massaging elements 102, 102, 102 that are fixed on the plate. The first set of massaging elements 102, 102, 102 are located on a top surface 117 of the first plate 104. The second plate 105 comprises a second set of massaging elements 101, 103, 101, 103. The second set of massaging elements 101, 103, 101, 103 are located and fixed on the top surface 116 of the second plate 105. The first plate 104 comprises a plurality of through-holes which are aligned with the position of the second set of massaging elements 101, 103, 101, 103 such that when the first plate 104 is positioned on top of the second plate 105 the second set of massaging elements 101, 103, 101, 103 protrude the through-holes. This allows the first plate 104 to be positioned on top of the second plate 105. The plurality of through-holes of the first plate 104 are distributed among the first set of massaging elements 102, 102, 102. The first plate 104 is positioned on the top surface 116 of the second plate 105, the first set of massaging elements 102, 102, 102 facing away from that top surface 116. The first and second set of massaging elements form a massaging surface.

[0072] FIG. 2 and FIG. 3 illustrate the situation where the first plate 104 and the second plate 105 are moved relative to each other, over a distance D. In a preferred embodiment, distance D equals the lowest motion that will generate the massage into the desired depth into the skin.

[0073] In a first stage, the device as illustrated in FIG. 2 is placed against a skin surface. In a second stage and as illustrated in FIG. 3, the first plate 104 and the second plate 105 are moved relative to each other. While doing so, the second massaging element 102 moves away from the first massaging element 101 and approaches the third massaging element 103. The effect of this is that the movement of the first 101 and second 102 massaging elements away from each other has a stretching effect on the skin present underneath the first 101 and the second 102 massaging element. At the same time, the second massaging element 102 moves closer to the third massaging element 103. This movement has a pinching effect on the skin present underneath the second 102 and the third 103 massaging element.

[0074] Thus, a simultaneous pinching and stretching effect on the skin is caused by the simultaneous application of differently directed forces on the skin. Because of the simultaneous application, the net-force on the user handling the device is substantially zero. This makes the device extremely easy to handle by the user and allows it to be implemented in a portable handheld massaging device.

[0075] In other words, the force exerted on the skin, tangential to the skin, of the massaging elements of the first plate is approximately equal and in opposite direction to the force exerted by the massaging elements of the second plate. Having that force evenly created by the several massaging elements makes the net-force on the skin and on the handling approximately zero.

[0076] According to an embodiment the first and/or the second plates are circular. This allows an easy integration in a handheld massaging device. In such an embodiment, the movement of the plates relative to each other may be rotational.

[0077] According to an embodiment of the invention, one or both plates are made from a flexible material, for example a rubber. This allows the plates to conform to the contours of the skin when applied or pressed against the skin. The flexibility can also be achieved through a mechanical construction of the plates. For example, the plates may be segmented whereby the different segments are able to conform to the shape of the skin. As illustrated in FIG. 4, the skin surface 111 that is in contact with the massaging surface experiences simultaneous pinching and stretching effects. A plurality of skin surface areas are exposed to these simultaneous pinching and stretching forces resulting in a pleasant massaging effect which can be easily applied by the user on the skin because of the net-force on the user being substantially zero.

[0078] FIG. 5 illustrates an embodiment of the first plate 104. The plate 104 comprises a plurality of massaging elements 101, 103. The plate 104 comprises plurality of through-holes 106. The through-holes are holes that completely penetrate the plate 104. The massaging elements are distributed over the surface of the plate 104, in rows or columns. The through-holes are distributed over the surface of the plate 104, in rows or columns. Rows or columns of through-holes 106 are located in between rows or columns of massaging elements 101, 103. Each row or column of through-holes is located in between two rows or columns of massaging elements.

[0079] FIG. 6 illustrates a second plate 105. The plate 105 comprises a plurality of massaging elements 102. The locations of the massaging elements 102 on the second plate 105 are aligned with the location of the through-holes 106 in the first plate 104 such that the first 104 and second 105 plate can be placed on top of each other and interlock. The massaging elements 102 penetrate the first plate 104 while doing so and eventually protrude from the first plate 104 as illustrated in FIG. 7.

[0080] FIG. 7 illustrates the first plate 104 being positioned on top of the second plate 105. The massaging elements of the first 104 and the second plate 105 thereby forming a massaging surface of massaging elements 101, 102, 103 from the first 104 and the second plate 105. To realize this, the height of the massaging elements 102 on the second plate 105 may be about the sum of the thickness of the first plate 104 and the height of the massaging elements 101, 103 of the first plate 104. This way, when positioning the first plate 104 on top of the second plate 105, an even massaging surface comprising massaging elements 101, 102, 103 of the first 104 and the second plate 105 is realized.

[0081] FIG. 8 illustrates a massaging device 100 comprising a first massaging element 101. The first massaging element 101 is an open and hollow structure. The surface of the first massaging element may be ring or oval shaped. For example, the first massaging element 101 may be a torus, e.g. an oblong torus. Within the first massaging element 101 a second massaging element 102 is present that can move relative to the first massaging element 101. The second massaging element 102 protrudes through a through-hole 106 that is present within the first massaging element 101. When the massaging element is placed against the skin and the massaging elements 101, 102 are moved relative to each other, the skin experiences a simultaneous pinch and stretch effect as explained above. Thus, in such an embodiment, the massaging surface comprises a surface having a plurality of open hollow structures, wherein each open hollow structure features a moveable massaging element present inside the open hollow structure.

[0082] FIG. 9 illustrates a cross section of FIG. 8. The first massaging element 101 is located on a first plate 104. The part of the plate present in the space 122 within the first massaging element 101 features a through-hole 106. A massaging element 102 which is located on a second plate 105 protrudes through the through-hole 106. The first plate 104 is located on top of the second plate 105. By moving the plates 104, 105 relative to each other, the second massaging element 102 moves within the through-hole 106 and causes a simultaneous pinching and stretching effect when applied to the skin. Thus, in such an embodiment the massaging device 100 comprises a first plate 104 with open hollow structures 101 having a through-hole 106 in each open hollow structure 101. The first plate 104 is positioned on top of a second plate 105 comprising massaging elements 102 of which the position on the second plate 105 is aligned with the through-holes 106 in the first plate 104.

[0083] FIG. 10 illustrates a massaging device as also illustrated in FIG. 8 and FIG. 9. The first 101 and the second 102 massaging elements are applied to a skin surface 111. FIG. 11 illustrates skin region 118 being pinched by the relative movement of the massaging elements 101, 102. Also, while skin region 118 is pinched, simultaneously, skin region 119 is stretched. Thus, two simultaneous and differently directed forces are applied to skin surface 111. FIG. 12 illustrates skin region 121 being pinched by the relative movement of the massaging elements 101, 102. Also, while skin region 121 is pinched, simultaneously, skin region 120 is stretched.

[0084] FIG. 13 illustrates a massaging device comprising a handle 108. The handle 108 is used to easily move the first 104 and the second plate 105 relative to each other after brining the massaging device in contact with the skin 111. The handle 108 is attached to the second plate 105. Optionally, in between the second plate 105 and the handle 108 a resilient material 107 is present. The resilient material 107 is flexible in one direction but resilient in other directions. The resilient material 107 may be placed such that it is flexible in the direction required to move the plates 104, 105 relative to each other. The resilient material may comprise leaf spring. The resilient material may comprise air compartments that are oriented perpendicular to the direction in which the resilient material is flexible, as illustrated in FIG. 19.

[0085] According to embodiment of the invention, the massaging device comprises a means for moving the plates 104, 105 relative to each other. This may be a motor. The motor may be coupled to the first plate 104 only. Alternatively, the motor may be coupled to the second plate 105 only. Alternatively, the motor may be coupled to the first 104 and the second plate 105.

[0086] According to a particular embodiment, the means for moving the plates 104, 105 relative to each other is coupled to one of the plates 104, 105 and is configured to drive one of the plates 104, 105 with an oscillating, angular motion. For example, in that embodiment, the plates 104, 105 are driven reciprocally over an angle of 15 degrees. In other words, the means for moving the plates 104, 105 is configured to actuate massaging elements such that they make an arcuate reciprocal motion through arcuate through-holes.

[0087] FIG. 14 illustrates a massaging device 100 comprising a means 108 for moving the first 104 and the second 105 plate relative to each other. The means is connected to the first plate 104 with a first mechanical linkage. The means is further connected to the second plate 105 with a second mechanical linkage. The oscillating or reciprocating motion of the two plates can cause a net-force load on the user. To minimize the load experience by the user, the means is balanced by being fixed to the half-way motion of the plates via the mechanical linkages thereby keeping it close to zero motion relative to the skin. Alternatively, this effect can also be achieved using one or more elastic elements.

[0088] FIG. 15 illustrates a massaging device 100 comprising a circular first plate 104 and a circular second plate 105 and a massaging surface comprised of massaging elements 101, 102, 103.

[0089] The first plate 104 is illustrated in FIG. 16 and comprises a plurality of massaging elements 101, 103, and a plurality of through-holes 106. The plate 104 features an outer circle 128 (imaginary indicated in FIG. 16 with a dashed line) formed of massaging elements 101, 103 and through-holes 106. In between all adjacent massaging elements 101, 103 along the circle a through-hole 106 is present in the plate 104. In other words, along the outer circle 128, adjacent to each massaging element a through-hole 106 is present in the plate 104. The plate 104 further features an inner circle 129 (imaginary indicated in FIG. 16 with a dashed line) formed of massaging elements and through-holes. Similar to the outer circle 128, in between adjacent massaging elements along the circle, a through-hole is present. In other words, along the inner circle 129, adjacent to each massaging element a through-hole is present. The through-holes 106 in the plate 104 have an arcuate shape to allow an arcuate motion of a massaging element in each through-hole. The inner and outer circles are concentric circles having a common center.

[0090] The second plate 105 is illustrated in FIG. 17 and comprises a plurality of massaging elements 102. The location of the massaging elements 102 are aligned with the location of the through-holes 106 in first plate 104. This allows the first plate 104 to be positioned on top of the second plate 105 whereby the massaging elements 102 of the second plate 105 fit through the through-holes 106 of the first plate. The fitted plates are illustrated in FIG. 15.

[0091] To create a massaging effect on the skin, the massaging elements 101, 102, 103 are applied to the skin. The plates 104, 105 are moved relative to each other by rotating one of the plate or by rotating both plates in opposite directions. By this rotational motion, the massaging elements of the second plate 105 fitting through the through-holes 106 move within the arcuate shaped through-holes 106. The rotational motion may comprise a continuously alternating clockwise/counter-clockwise motion. To generate this movement, an appropriate mechanical system may be coupled to, for example, a motor. The mechanical system may be adapted to translate the motion provided by the motor into a back and forth or into a continuously alternating clockwise/counter-clockwise motion.

[0092] According to an embodiment of the invention, the massaging device comprises a plurality of massaging elements, the elements being positioned in multiple concentric circles. Massaging elements within each circle move relative to each other thereby creating a massaging effect to the skin. The massaging elements are moved such that the net-result of forces exercised on the skin is substantially zero within each circle. This effect may be achieved by three consecutive massaging elements in a circle, wherein the middle one of the consecutive massaging elements moves relative to the other two massaging elements. Further, the massaging device may comprise three or more concentric circles with massaging elements. In these embodiments, each circle of massaging elements provides a massaging effect to the skin.

[0093] Further, the massaging device may comprise two or more sets of concentric circles of massaging elements wherein the center of each set is at a different location. Each set may be driven by a different motor or a mechanical system may be added that translates the motion of a single motor differently to different sets.

[0094] While the massaging elements and through-holes are throughout the description described as forming a circular shape, the position of the elements and the through-holes may deviate from that circular shape.

[0095] In embodiments of the invention, the massaging elements 101, 103 and through-holes 106 may be positioned in different concentric circles in or on the plate 104. The plate 104 may comprise a first circle formed by massaging elements 101, 103. For example, a first circle being formed only by massaging elements 101, 103. The plate 104 may further comprise a second circle formed by through-holes 106. For example, a second circle being formed only by through-holes 106. The plate 104 may comprise a plurality of concentric circles, the circles alternating between a circle formed by massaging elements 101, 103 and a circle formed by through-holes 106. The massaging elements 102 of the second plate 105 are aligned with the position of the through-holes 106 in the first plate 104.

[0096] FIG. 18 illustrates the attachment of a massaging device 100 to a personal health or hand-held device 126. The massaging device 100 comprises a connector 123 which can be received by a receptacle 124 which is part of the hand-held device 126. The connector 123 and receptacle 124 may be based on a mechanical click-on principle. This allows the user to easily replace the massaging device 100. A mechanical system 125, e.g. mechanical driving interface connection, is present which translates the motion of a motor present in the handheld device 126 into an appropriate motion, e.g. a rotational motion, to drive the massaging elements of the massaging device 100. The mechanical system 125 may be part of the massaging device 100 or may be part of the hand-held device 126.

[0097] FIG. 19 illustrates an embodiment of a resilient material 107 which is flexible in a first direction and resilient in a second direction. The direction in which the resilient material 107 is flexible may be the same direction in which the plates are moveable relative to each other. In a particular embodiment the material comprises air compartments 127 oriented perpendicular to the first direction.

[0098] The dimensions of the massaging device may be adapted to the particular application of the massaging device. For example, the massaging surface area of the massaging device for massaging the skin of the face may be a few cm.sup.2, for example between 1 and 10 cm.sup.2. For example, the massaging surface area of the massaging device for massaging other parts of the body may be tens of cm.sup.2, for example between 10 and 100 cm.sup.2. For example, the massaging surface area of the massaging device for massaging the scalp may be between 10 and 250 cm.sup.2.
