[0080] FIGS. 17 to 20 show side views of various dental cleaning elements at a holder in each case.

[0081] FIG. 1 shows a base body 1 for a dental cleaning system 2 according to the following FIGS. 3, 4, 6, 7, and 9. The base body 1 comprises a recess 4 extending in a longitudinal direction 3 for accommodating a fingertip (not represented). In FIG. 1, the longitudinal direction 3 extends into the sheet plane. The base body 1 is designed to be annular. The base body 1 can also be designed to be U-shaped (cf. FIG. 8).

[0082] The recess 4 comprises a conically shaped inner surface 5 and, therefore, a first recess opening 6 is larger than a second recess opening 7 offset along the longitudinal direction 3. Therefore, the recess 4 is designed to be essentially complementary to the finger. It would be conceivable that the recess 4 comprises only the first recess opening 6 and is designed in the shape of a thimble. The two recess openings 6, 7 can also have the same size, and so the recess is cylindrically shaped.

[0083] Recesses 4 having different sizes are made available for different finger shapes. Moreover, the inner surface 5 is designed to be polygonal, and so the base body 1 and, therefore, the dental cleaning system 2 according to FIGS. 3 and 4, is held in a rotatably fixed manner on the finger, in particular, the index finger.

[0084] The base body 1 has several, preferably four, sides. A first grip surface 9 is situated on each of two opposite sides. The two first grip surfaces 9 are provided for controlling the movement of the base body or of the dental cleaning system (cf. FIGS. 3, 4, 6, 7, and 9) in the oral cavity. Preferably, the thumb and the middle finger engage on the two first grip surfaces 9 in order to hold the base body 1. The two first grip surfaces 9 form a wing-type surface which projects over the base body 1. The first grip surface 9 extends along the longitudinal direction 3 of the base body 1.

[0085] A second grip surface 10 is provided between the two first grip surfaces 9. The second grip surface 10 is utilized as a further control surface for the thumb. One or several grip surfaces can include a non-slip surface in order to improve the feel during the handling. The grip surfaces 9, 10 can be curved, perforated, and/or ribbed.

[0086] The base body 1 comprises at least one slot 11 on its side opposite to the second grip surface 10. The slot 11 is designed for connecting the base body 1 to a holder 12 of the dental cleaning system 2. The slot 11 and the holder 12 are designed to be complementary to one another in such a way that the holder 12 can be at least partially accommodated by the slot.

[0087] The base body 1 comprises a first part 13 of a fastening system 14 (cf. FIGS. 3 and 4), with the aid of which the holder 12 can be positioned on the base body 1. According to FIG. 1, the first part 13 of the fastening system 14 is a fastening carriage 15. The fastening carriage 15 comprises a first guide surface 16 which is designed to be U-shaped. The fastening carriage 15 tapers in the longitudinal direction 3, as is represented in FIG. 1 with the aid of a dashed line 17. The fastening carriage 15 is therefore essentially conical, and so the widening area ensures that the fastening carriage 15 is braced against an area of the holder 12 provided therefor (cf. FIGS. 3 and 4).

[0088] FIG. 2 shows the holder 12 for the dental cleaning system 2 (cf. FIGS. 3, 4, 6, 7, and 9), which is designed, in particular, for connection to the base body 1 (cf. FIGS. 1, 8) and for tensioning dental floss 18. The holder 12 comprises two mutually spaced brackets 19, between which the dental floss 18 is held. The dental floss 18 is connected to the brackets 19 with the aid of at least one fastening element 22. Thus, for example, the dental floss 18 can be wound around the fastening element 22 and/or clamped therein. The dental floss 18 can also be fixedly connected to the brackets 19 or embedded therein, as is represented in FIGS. 3 and 4.

[0089] The holder 12 comprises a second part 20 of the fastening system 14, and so the holder 12 can be connected to the base body 1 (cf. FIGS. 1, 8) in a force-locked and/or form-locking manner. According to the present exemplary embodiment, the second part 20 of the fastening system 14 is a fastening rail 21 for accommodating the fastening carriage 15 of the base body 1. The fastening rail 21 comprises a second guide surface 23. The second guide surface 23 is designed to be U-shaped, and so the fastening carriage 15 of the base body 1 can be accommodated therein. A spring 24 is formed on the fastening rail 21, which engages into the slot 11 of the base body 1, and so, essentially, a groove-spring connection can be formed.

[0090] Between the two brackets 19 and the dental floss 18, a stop 26 is situated on an inner side 25 of the holder 12, and so the introduction of the dental floss 18 into the interdental space is limited. Holders 12 can be provided with different stops 26 or no stops 26 in order to ensure a gentle handling without injuring the individual gum.

[0091] The surface of the fastening carriage 15 (FIG. 1) has a convexity having a small radius r. The corresponding surface of the fastening rail 21 (FIG. 2) has a larger radius R, however. If the holder 12 and the base body 1 are connected to one another, a bending of the holder 12 occurs, whereby the two brackets 19 are bent apart from one another. A tensioning of the dental floss 18 results, which considerably facilitates the insertion of the dental floss 18 into the interdental space and the cleaning thereof. Such a movement of the brackets 19 can also be effectuated by way of an appropriate dimensioning of the slots 11 and the springs 24. In order to facilitate the connection of the fastening carriage 15 and the fastening rail 21, it can be provided that a large amount of play is initially provided, which finally decreases and, thus, results in a clamping only upon further insertion of the spring 24 into the slot 11.

[0092] FIG. 3 shows the dental cleaning system 2 comprising the base body 1 and the holder 12, each according to one alternative embodiment. In contrast to the base body 1 shown in FIG. 1 and the holder 12 shown in FIG. 2, the two guide surfaces 16, 23 are designed in a dovetail shape in this case.

[0093] The guide surfaces 16, 23 of the base body 1 and of the holder 12, respectively, are not parallel to one another in the non-assembled state, as is represented in FIGS. 1 and 2. When the holder 12 or its fastening rail 21 is slid onto the fastening carriage 15 or the base body, the holder 12 spreads apart in such a way that the dental floss 18 is tensioned between the brackets 19. Therefore, when the holder 12 and the base body 1 are not connected to one another to form the dental cleaning system 2, the dental floss 18 is essentially held loosely between the brackets 19. The dental floss 18 is first tensioned by way of the connection of the two parts 13, 20 of the fastening system, in particular, the connection of the fastening carriage 15 to the fastening rail 21. The tension of the dental floss is established in such a way that an ideal cleaning of the interdental spaces can take place.

[0094] According to FIG. 3, the dental floss 18 is fixedly connected to the brackets 19, wherein one end of the dental floss 18 is molded into a bracket 19 in each case. Alternatively, as represented in FIG. 2, the dental floss 18 can be fastened to the holder 12 with the aid of the fastening element, and so the dental floss 18 can be replaced at any time, as necessary. In order to replace the dental floss 18, according to FIG. 3, on the dental cleaning system 2, the holder 12 is removed from the dental cleaning system 2 and a new holder (not represented) is connected to the base body 1.

[0095] The fastening system 14 of the dental cleaning system 2 is additionally secured with the aid of a locking mechanism 27 which is merely schematically indicated in FIG. 3. The locking mechanism 27 can be designed, for example, to include a magnet, a snap-in connection, or a push button.

[0096] Moreover, a retaining element 28 is installed on the dental cleaning system 2, which safeguards the holder 12 and/or the base body 1 against being swallowed. The retaining element 28 is designed as a thread which can be fastened on the hand and is fastened to the holder 12 and/or the base body 1.

[0097] FIG. 4 shows a perspective representation of the dental cleaning system 2. The base body 1 and the holder 12 are connected to one another by the fastening system 14, in particular, the fastening carriage 15 has been slid into the fastening rail 21. Since the guide surfaces 16, 23 (cf. FIGS. 1 and 2) extend askew with respect to one another, the holder 12 spreads apart on the base body 1 in such a way that the dental floss 18 is tensioned.

[0098] The inner surface 5 of the base body is designed to be conical and polygonal, and so the entire dental cleaning system 2 is held on the finger in a rotatably fixed manner when the dental cleaning system 2 is utilized, in particular, in the oral cavity. Preferably, different sizes and geometries of the dental cleaning system 2 are made available for different finger shapes. Thus, smaller dental cleaning systems 2 are also suitable for small fingers, wherein, in particular, the recess 4 of the base body 1 is reduced in size.

[0099] FIG. 5a shows the holder 12 as well as its second guide surface 23 and FIG. 5b shows the base body 1 comprising the first guide surface 16. The geometry of the second guide surface 23 can differ from the geometry of the first guide surface 16. In this case, the two guide surfaces 16, 23 are not parallel to one another, in particular, when the holder 12 is situated with respect to the base body 1 in such a way that the two guide surfaces 16, 23 face one another. As a result, a spreading or clamping of the holder 12 on the base body 1 can be achieved.

[0100] As is also described according to FIG. 1, the first guide surface 16 is designed to be conical, wherein the fastening carriage 15 describes a first taper angle 29. The second guide surface 23 can also be designed to be conical, although preferably having a smaller second taper angle 30. When the fastening carriage 15 is slid into the fastening rail 21, the larger first guide surface 16, due to its larger first taper angle 29, spreads the smaller second taper angle 30 or the second guide surface apart, and so the dental floss 18 (cf. FIGS. 3, 4, 7, 9) is tensioned.

[0101] One of the taper angles 29, 30 can be equal to zero in this case, and so the guide surface is essentially straight.

[0102] FIG. 6 shows a side view of the dental cleaning system 2 which is equipped with an adjusting mechanism 31. According to FIG. 6, the adjusting mechanism 31 is designed as a size-adjustable tube clamp 32 for varying the diameter of the recess 4. Due to the fact that the tube clamp 32 is fixed, the recess 4 of the base body 1 reduces in size, and so the dental cleaning system 2 is suitable for smaller fingers. The base body 1 is provided with a slot 34 in order to make it easy to reduce the size of the base body 1. The diameter of the base body 1 can be reduced by tightening the tube clamp 32.

[0103] In addition to the adjusting mechanism 31, FIG. 6 shows that the brackets 19 of the holder 12 are situated obliquely with respect to the fastening rail 21 thereof and with respect to the longitudinal axis 3 of the base body 1.

[0104] In FIG. 6, another locking mechanism 27 for the holder 12 on the base body is also represented, in a sketched manner. This is a small tab which snaps into a recess in the base body 1. An inadvertent release of the connection between the base body 1 and the holder 12 is therefore avoided. For the purpose of releasing the connection, it can be provided that the tab breaks at an intended breaking point in order to indicate that the dental floss has already been used and should not be used once again.

[0105] FIG. 7 shows that the base body 1 and the holder 12 are connected to one another as one piece to form the dental cleaning system 2. The dental cleaning system 2 therefore does not comprise a fastening system 14 according to the preceding figures. In order to ensure that the entire dental cleaning system 2 does not need to be replaced when the dental floss 18 is replaced, the dental cleaning system 2 can comprise a fastening element 22 according to FIG. 2. The fastening element 22 makes it possible to replace only the dental floss 18.

[0106] Moreover, an alternative embodiment of the adjusting mechanism is formed in the recess 4, which is a ring insert 33 according to FIG. 7.

[0107] The ring insert 33 is separately formed and can be placed into the recess in order to reduce the size of the recess. In this way, the dental cleaning system 2 is easily adapted to different finger shapes and sizes.

[0108] FIG. 8 shows the base body 1 according to an alternative embodiment, wherein the base body 1 is designed to be U-shaped. The base body 1 comprises a third recess opening 8 which is situated in the area of the fastening carriage 15. It is also conceivable that the recess opening 8 is situated on the other sides of the base body 1.

[0109] FIG. 9 shows that the fastening system 14 can also be oriented transversely with respect to the longitudinal direction 3 of the base body. In order to connect the fastening carriage 15 and the fastening rail 21 to one another, the holder 12 is slid onto the base body 1 transversely with respect to the longitudinal direction 3.

[0110] Due to a predefined, different bending of the fastening carriage 15 and the fastening rail 21 in the insertion direction, a pre-tensioning of the dental floss 12 arises, since the brackets 19 move away from one another, at the end thereof to which the dental floss is fastened (see FIG. 2). In the relaxed state, before the fastening carriage 15 has been slid into the fastening rail 21, the radius of the fastening carriage 15 is greater than the radius of the fastening rail 21. In contrast to the preceding figures, the base body 1 comprises the fastening rail 21 and the holder 12 comprises the fastening carriage 15. In this FIG. 9, it is also indicated that the surface of the grip surface is structured, specifically, ribbed in this case, in order to improve the guidance of the dental cleaning system 2.

[0111] FIG. 10 shows a base body 1 similar to FIG. 1. The only difference is that a second fastening carriage 15′ is provided in addition to the fastening carriage 15. The second fastening carriage 15′ is dimensioned smaller in this case and, therefore, is suitable for the accommodation of a smaller holder according to FIG. 2. Of course, a second accommodation similar to the embodiment according to FIG. 9 can also be situated transversely with respect to the longitudinal direction 3 of the base body 1 or even a combination of both types of the accommodation.

[0112] In FIG. 11, a top view of a dental cleaning system according to a further exemplary embodiment is represented. In this top view, the base body 1 comprising the two first grip surfaces 9 is shown. The fastening carriage 15 as well as the first guide surface 16 of the fastening system 14 are arranged at the base body 1. While the holder 12 was connected to the base body 1 with the aid of a linear movement in the preceding exemplary embodiments, a rotary motion is necessary in this exemplary embodiment, in order to fasten the holder 12 at the base body 1. The holder 12 comprises two brackets 19, at which the dental floss 18 is fastened. In order to insert the holder 12 into the base body 1, the holder 12 is rotated toward the right, in the double-arrow direction D, by approximately 90° with respect to the representation shown here and is inserted onto a centering pin 35 of the base body 1. Thereafter, the holder 12 is rotated toward the left, in the double-arrow direction D again, by approximately 90° around the centering pin 35 and on the fastening carriage 15 and becomes fixed, for example, in a dovetail groove of the first guide surface 16. The second guide surface 23 of the holder 12 corresponds to the first guide surface 16 of the base body 1.

[0113] Due to this fastening of the holder 12 on the base body 1, either the holder 12 is bent in such a way that the brackets 19 are slightly spread apart at their upper ends, whereby the dental floss 18 is tensioned across its effective length B. Alternatively, only the area at which the brackets 19 are fastened at the holder 12 can also be elastically deformed with respect to the holder 12 and also spread the brackets 19 apart with the aid of appropriate guide surfaces. The effective length B of the dental floss 18 for cleaning the interdental space is also located in the intermediate space between the two brackets 19 and, therefore, is tensioned.

[0114] FIG. 12 shows a section through a side view of the dental cleaning system similar to FIG. 11. In this case, the centering pin 35, which is part of the base body 1, is apparent again. Of course, conversely, the centering pin 35 could also be part of the holder 12 and could be introduced into an opening of the base body 1. The first guide surface 16 and the second guide surface 23 cooperate, and so the holder 12 is fixed on the base body 1. At the holder 12, in this sectional representation, one of the two brackets 19 as well as a section through the dental floss 18 are apparent.

[0115] The centering pin 35 extends with a height H past the top side of the second guide surface 23 of the holder 12, whereby the distance A between the centering pin 35 and the dental floss 18 is determined. This distance A is less than the distance would be between the dental floss 18 and the top side of the holder 12, which the tooth would impact without the stop 26. The distance A therefore forms a dimension representing how far the dental floss can penetrate the interdental space. When the dental floss 18 is introduced into an interdental space, the stop 26 impacts the top side of the tooth and, therefore, limits the penetration depth of the dental floss 18. Depending on the individual jaw of the user, the distance A can be individually adapted, as a result, with the aid of various base bodies 1 having centering pins 35 of different lengths. Alternatively, it is also possible to make different holders 12 available, in the case of which the brackets 19 have a different length L. The length L of the brackets 19 is determined in this case as the distance between the dental floss 18 and the fastening of the bracket 19 at the holder 12 or, according to other exemplary embodiments, at the base body 1. As a result thereof as well, the distance A with respect to a stop 26 of the centering pin 35 or the top side of the holder 12 in the area of the two brackets 19 is individually set to the needs of the user.

[0116] In the exemplary embodiment from FIG. 13, which shows a section through a side view of the dental cleaning system similar to FIG. 11, the stop 26 is formed by a stop piece 36. The stop piece 36 has been inserted onto the centering pin 35 and, there, determines the distance A of the stop 26 from the dental floss 18.

[0117] In this exemplary embodiment, the height H of the stop piece 36 can be adjusted, in height, with respect to the dental floss 18. This can take place either with the aid of various notches, wherein the stop piece 36 is inserted onto the centering pin 35 to a more or less deep extent. Alternatively, it is also possible, as represented here, that a thread 37 or an appropriate inclined surface is provided. The stop piece 36 is screwed onto the centering pin 35 and, as a result, changes the height H with respect to the top side of the holder 12 or the distance A to the dental floss 18. In this case as well, in a further alternative, it is possible that the brackets 19 of the holder 12 are designed to be longitudinally adjustable and become more or less long, for example, with the aid of telescopic displacement and, as a result, affect the distance A.

[0118] FIG. 14 shows a top view of a dental cleaning system comprising a handle 40 according to a further exemplary embodiment. This is a conventional dental cleaning system comprising a handle 40 and two brackets 19 designed in the shape of a fork, between which the dental floss 18 is tensioned. The stop 26 comprising a stop piece 36 for a tooth is fastened at a displacement part 38. The displacement part 38 is displaceable according to the direction of the double arrow V. As a result, the distance A between the dental floss 18 and the stop 26 or the height H between the top side of the stop piece 36 and the lowest point of the handle 40 between the brackets 19, at which a tooth would impact, is determined. In order to retain the selected distance A, the handle 40 comprises notches 39, which correspond to the displacement part 38. The displacement of the displacement part 38 therefore requires a certain amount of force, which prevents the distance A from being inadvertently changed. Alternatively, the effective length L of the brackets 19 can also be changed, for example, with the aid of a telescopic embodiment (not represented) of the brackets 19.

[0119] In order to utilize fewer plastics and, therefore, to reduce the burden on the environment, it can be provided that the holder 12 and/or the base body 1 and/or the stop 26 are/is manufactured from a renewable and, in particular, consumable raw material. Therefore, the risk of an injury to a user is also avoided in the case of inadvertent swallowing. In addition, if it also provided that good-tasting material is utilized, for example, for the application for children, an incentive to use the dental cleaning system can be created. After cleaning the interdental space, the user can eat the dental cleaning system or at least parts thereof. It is also advantageous when the material of the dental cleaning system is bio-compostable. This contributes to a considerable reduction of plastic waste.

[0120] FIG. 15 shows a side view of the dental cleaning system 2 according to an alternative, two-pieced embodiment. The dental cleaning system 2 comprises the base body 1 and the holder 12. The holder 12 can be connected to the base body 1, in that it is inserted onto the base body 1 in the insertion direction E and, thereafter, is rotated in direction of rotation D. As a result, a two-pieced fastening system locks in position, in the case of which two first guide surfaces 16 and two second guide surfaces 23, on each side of the holder 12, are connected to each other. While the first, lower guide surface 16, together with the second, lower guide surface 23, brings about a strong hold between the holder 12 and the base body 1, the upper guide surfaces 16 and 23 cause the brackets 19 to spread apart and, therefore, tension the dental floss 18.

[0121] Moreover, in this exemplary embodiment, it is apparent that two stops 26 are arranged at the holder 12. As a result, a distance A for the dental cleaning system 2 is created, and so the dental floss 18 cannot cut into the gums, since it is stopped as soon as the stops 26 impact the tooth surface. The distance A can be determined by the height H of the stops 26 or by the effective length L of the brackets 19.

[0122] The holder 12, which is represented in cross section in this exemplary embodiment, shows that the brackets 19 are designed in a reinforced manner. Accordingly, they comprise two sections extending essentially in parallel, which facilitate the manufacture, on the one hand, and, on the other hand, create an additional stability for the fastening and tensioning of the dental floss 18.

[0123] In FIG. 16, a side view of the dental cleaning system 2 according to an alternative, one-pieced embodiment is shown. In this embodiment, a toothbrush 41 is arranged at the brackets 19 and at the intermediate space between the two brackets 19 at the holder 12. Similarly to the dental floss 18, the toothbrush 41 can be optimally guided with the aid of the fingers by the holder 12 according to the invention and the base body 1. As a result, a very positive cleaning effect is achieved.

[0124] FIGS. 17 through 20 show side views of various dental cleaning elements at a holder 12 in each case. In FIG. 17, a toothpick 42 is arranged at the holder 12. FIG. 18 comprises an interdental brush 43 at the holder 12. The arrangement of the dental cleaning elements can also be on the top side or the other side of the holder 12, in deviation from the representation in the present case. The angle of the arrangement can also not be 90°, as represented here, but rather can be an acute or obtuse angle.

[0125] In FIG. 19, a type of the toothbrush 41 is represented that is modified as compared to FIG. 16. In FIG. 20, a tongue cleaner 44 is fastened at the holder 12. The tongue cleaner 44 can comprise a rough surface.

[0126] The holders 12 shown here can each be combined with a base body 1. Of course, it is also possible that these dental cleaning elements are arranged in a one-pieced design of the dental cleaning system 2.

[0127] The present invention is not limited to the represented and described exemplary embodiments. Modifications within the scope of the claims, for example, by arranging the stop at the brackets or at the base body, are also possible, as is any combination of the features, even if they are represented and described in different exemplary embodiments. It is also possible, in particular, to differently establish the angle between the handle or the base body and the brackets, at which the dental floss is fastened, as necessary. It is merely important that the stop is arranged in such a way that it can prevent an injury of the gums. For the rest, it is also possible, of course, that the invention or parts thereof is/are utilized on manually utilized dental cleaning systems, as well as on toothbrushes, electric toothbrushes, electric dental cleaning systems, or interdental brushes.
