Abstract

Brush-head segments (3,5) link to articulated joints. Together the segments and the joints operate so that a swiveling movement in each brush-head segment on each articulated joint causes bundles of bristles (7,8,10,11) in the same brush-head segments and/or adjacent brush-head segments to be lifted across a surface as a reaction to the application of pressure to the bundles of bristles fastened to the brush-head segments.

Description

The invention relates to a brush, in particular a toothbrush with a handle handle and a bristle bundle-carrying brush head having at least two bristle bundles occupied brush head segments which are movable relative to each other, wherein the bristle bundles of the brush head segments protrude through a use-side surface of the brush head.

Such brushes are well known in particular as toothbrushes. The relative mobility of the brush head segments to prevent a punctual position of the use-side ends of individual bristle bundles. Due to the relative mobility of the brush head segments is due to the initially selective stress loaded brush head segments elastically pivot, so that the pressure initially stressed bristle bundles evades the compressive stress until the compressive force is distributed more uniformly by planting a plurality of bristle bundles, so that there is a flat transmission of the contact pressure. Such transmission prevents toothbrushes, for example, excessive stress on the sensitive oral mucosa.

A generic brush is for example from the DE 10 2004 020 706 known. In this brush designed as a toothbrush brush head segment is slidably mounted in the front region of the brush head in the longitudinal direction of the bristle bundles, namely elastically against the restoring force of a provided on the back of the brush head membrane. The front bristle bundles can accordingly evade a higher compressive stress. They are in the initial state a little longer than the bristle bundles of the other brush head segment.

Generic brushes are usually similar to that of the DE-U-94 02 125 trained toothbrush. The brush head segments are arranged in this prior art in the longitudinal extension of the brush in succession and connected to each other via a hinge, so that the brush head segments of a plane containing the longitudinal axis of the brush head can pivot (bending the longitudinal axis). The successively arranged brush head segments are then not stiff in the axial direction, but kept within limits movable to each other. The often overused bristle bundles of the front brush head segment can thus avoid excessive pressure stress by pivoting.

Another example of a generic brush is from the EP 0 761 124 known. In this prior art, the brush head segments are movably held in a frame which forms the outer contour of the brush head. The individual brush head segments are connected via a film hinge with this frame and pivotable relative thereto.

Another representative of the generic brush is from the US 6,178,582 known. In this prior art, the front brush head segment is connected via a plurality of thin webs with the underlying brush head segment. An encapsulation is provided between the two brush head segments, which fills the slot between the two brush head segments and envelops the webs.

The generic brushes want to achieve in particular a good cleaning of the surface to be cleaned in particular at the front end of the brush, but without taking an excessive compressive stress in purchasing.

However, it has been shown that the known proposals for solution make the desired surface conditioning of the bristle bundles insufficient, especially if a certain inclination between the longitudinal direction of the brush head and the surface to be cleaned is adjusted by the user and / or the surface to be cleaned has unevenness se complicate a full-scale investment of the bristle bundles on the surface to be cleaned.

The present invention has for its object to provide a brush of the type mentioned with improved cleaning behavior. The main focus of the invention is on a possible flat contact all provided on the brush head bristle bundles on the surface to be cleaned.

In view of this, the present invention proposes a brush having the features of claim 1. The brush according to the invention has at least one brush head segment, which is connected via a joint, ie connected to the handle stem and / or adjacent brush head segments with the interposition of a joint. The hinge and the brush head segment are formed so that a pivoting movement of the brush head segment about the hinge in response to a compressive stress on the attached to the brush head segment bristle bundles lifting out of Bristle bundles of the same brush head segment and / or adjacent brush head segments on the surface formed in the unclaimed state causes.

In departure from the known concepts in which the compressive stress of the bundles of bristles merely leads to an evasion of the brush head segment, it is proposed with the present invention, in response to such a compressive stress, the brush head segment which avoids compressive stress, or adjacent brush head segments in response thereto To lift out evasive movement relative to the surface of the brush head. Accordingly, these raised bristles lay flat against the surface to be cleaned, whereas the excessively stressed bristles adjacent thereto provide for deflection, i. be pivoted away from the surface of the brush head.

This special design of the joint and of the brush head improves the surface contact of the bristle filaments with the surface to be cleaned.

According to a preferred development of the present invention, the joint has a smaller dimension in the direction of its pivot axis than the brush head segment connected via the joint. Decisive for this comparison is in particular the dimension of the brush head segment immediately adjacent to the joint. The joint may be formed in particular as a film hinge or web-shaped connecting element. Due to the relatively small dimension of the joint with respect to the brush head segment, the possibility is created not only to set a pivoting movement on the joint, but also to allow a torsion. Accordingly, in response to excessive compressive stress, bristle bunches of a brush head segment may experience superimposed movements on this or adjacent brush head segments caused by pivotal movement along the pivot axis of the joint and / or torsional motion through the joint. The development discussed above should just allow a torsional movement of the brush head segment with respect to the ratio of dimension of the joint to dimension of the connected brush head segment. The joint should preferably have less than one fifth of the dimension of the adjacent brush head segment.

According to a further preferred embodiment of the present invention, the joint is designed as a pivot-torsion, so that this both the aforementioned pivoting movement as well as a torsional movement allowed. In particular torsion should be allowed as a torsion whose torsion axis is substantially parallel to the surface of the brush head segment, but extends at right angles or at least approximately at right angles to the pivot axis of the joint. Due to this design of the pivot-torsion joint, the brush head segment connected via this joint can pivot relative to the adjacent brush head segment in response to a compressive stress on the bristle bundle attached to the brush head segment, in a manner known per se along the pivot axis of the joint. In addition, the brush head segment can be twisted relative to the adjacent brush head segment about an axis extending parallel to the use-side surface.

According to a further preferred embodiment, the brush head segments are pivotable in a plane which extends substantially perpendicular to the longitudinal axis of the brush head. In departure from the known prior art, in which the pivot axis of a flexible brush head segment extends transversely to the longitudinal axis, so that the brush head segments are substantially parallel to the surface of the brush head and out of this plane, the brush head segments are preferably in the brush according to the invention pivotable in a plane substantially perpendicular to the longitudinal axis of the brush head. The longitudinal axis of the brush head can form the center of the pivoting movement. Alternatively, the center of pivotal movement may also be eccentric to the longitudinal axis, but preferably about an axis of rotation extending parallel to the longitudinal axis of the brush head.

According to a preferred development of the present invention, the brush head segments are arranged one behind the other in the longitudinal direction of the brush head and each carry a row of bristle bundles and are connected to one another via a web-shaped connecting element arranged between the brush head segments. This web-shaped connecting element in particular allows a pivoting movement of the individual brush head segments in a plane substantially perpendicular to the longitudinal axis.

Preferably, the brush according to the present invention brush head segments, which are each connected to each other only via a single connecting element. This web-shaped connecting element allows a pivoting movement of the individual brush head segments in a plane substantially perpendicular to the longitudinal axis of the brush head segment. Usually, the brush head segments form in the unclaimed state of a flat brush head surface from which the bristle bundles protrude substantially at right angles. At excessive compressive stress on one or more bristle bundles of the associated brush head segment of this brush head segment is elastically pivoted about the web-shaped connecting element, so that the associated brush head segment is displaced from the plane of the brush head to the rear, with increasing distance from the web-shaped connecting segment. This situation can be used to adjust the change in distance of individual bristle bundles of the brush head segment to the use-side ends of bristle bundles of other brush head segments and / or adjacent bristle bundles of the same brush head segment.

The brush head segments of the brush according to the invention usually extend over the entire width of the brush head. The web-shaped connecting element can be aligned with the central longitudinal axis of the brush head. Alternatively, the connecting element may also be provided on a longitudinal edge of the brush head. However, any position of the web-shaped connecting element between the central longitudinal axis and the edge is conceivable.

With a view to the most flexible adaptation of the use-side ends of the bristle bundles to the surface to be cleaned, it is preferable to provide only one row of bristle bundles on each individual brush head segment. This series usually extends substantially perpendicular to the longitudinal axis of the brush head, which generally coincides with the longitudinal extent of the web-shaped connecting segment. The longitudinal axis of the web-shaped connecting element is then provided in parallel with the longitudinal axis of the brush head. Again, this is usually the case with toothbrushes parallel to the longitudinal extension of the handle.

The web-shaped connecting element is preferably designed such that a bending moment generated by the bar-shaped connecting element above a limit value when the bristle bundle of one of the brush head segments is pressed against or near the edge leads to a pivoting movement of the brush head segment. This pivoting movement takes place around the web-shaped connecting element. In this preferred embodiment, the corresponding brush head segment remains regularly in the surface of the brush head at a conventional stress on this brush head segment provided bristle bundles, ie at subcritical bending moment. With the preferred development, in particular an excessive compressive stress of the edge-side bristle bundles is to be avoided. These are sometimes applied to a movement of the brush about its longitudinal axis with excessive pressure against the surface to be cleaned. In particular, such a stress in a toothbrush is to be feared when the brush is to be cleaned by turning the brush about the longitudinal axis from "red" to "white", that is, due to the movement of the brush bacteria and contamination of the gums towards the free ends the teeth should be urged. In an excessive stress of the bristle bundles on the edge of the brush head segments, ie at the free end of the corresponding brush head segment above a influenced by the design of the web-shaped connecting element limit value pivots the brush head segment, thus reducing the compressive stress of the or the bristle bundles, at the same time the plant of the other, previously not yet applied to the surface to be cleaned bristle bundles of the corresponding brush head segment is increased.

During the pivoting movement of the brush head segments, the web-shaped connecting elements preferably form a rest point with respect to the pivoting movement, which is stationary relative to the overall surface. This circumstance is used for the positionally accurate action of brush head segments according to a preferred embodiment of the present invention in that the web-shaped connecting elements extending in the longitudinal direction of the brush head carry bundles of bristles which extend in the longitudinal direction of the brush head. Preferably, these bristle bundles form an elongated bristle field extending in the longitudinal direction of the brush head, which is arranged not only in the longitudinal direction at the level of the web-shaped connecting element but completely or partially covers the brush head segments provided adjacent thereto. In other words, according to this preferred aspect of the present invention, an elongated bristle field is disposed on the web-shaped connecting elements with an orientation corresponding to the bending axis of adjacent brush head segments.

Further preferred embodiments of the present invention are specified in the subclaims.

The embodiments shown in the drawing are front ends of a toothbrush, of which only the brush head and a brush head near part of a handle handle 2, which is commonly referred to as a brush neck, are created.

Each of the brush heads 1 in the FIGS. 1 to 3 shown embodiments has a plurality of mutually parallel brush head segments 3, which are formed substantially block-like and connected to each other via web-shaped connecting elements 4. The arrangement of parallel brush head segments 3 is preceded by a brush head segment 5, which is arranged at the front end of the brush head 1 and is formed at its front end strongly curved. At the other end of the arrangement of the brush head segments 3, a rear brush head segment 6 is integrally provided with the handle handle 2. The front and rear brush head segments 5, 6 carry in the embodiments of FIGS. 2 and 3 in each case a single bristle bundle 7 or 8.

The rod-shaped brush head segments 3, which extend transversely to a longitudinal axis 9 of the brush head 1, are respectively bundles of bristles 10 which are arranged in parallel rows to one another and in the longitudinal direction of the rod-shaped brush head segments.

The front and rear brush head segments 5, 6 and the rod-shaped brush head segments 3 and the associated connecting elements 4 lie with their upper and lower sides in a plane and form a substantially flat in side view brush head 1 off. The protruding from the bristle bundles 7, 8, 10 surface of the corresponding elements of the brush head 1, which are integrally formed by way of injection molding.

The specific features of the individual embodiments are also discussed below:

At the in FIG. 1 Shown embodiment, the web-shaped connecting elements 4 each edge, ie provided at the longitudinal edge of the brush head 1. The connecting elements 4a, 4b holding the foremost rod-shaped brush head segment 3a are at the same, in FIG. 1 provided on the right margin. The remaining connecting elements 4c to 4f are provided on the opposite longitudinal side.

In addition to the central rear bristle bundle 8, the rear brush head segment 6 provides for three further bristle bundles 11, which are provided in a transverse row and parallel to the bristle bundles 10 of the rod-shaped brush head segments 3.

When using the in FIG. 1 shown embodiment and excessive stress on the bristle bundles 10 of the individual rod-shaped brush head segments 3, they can pivot about a pivot axis which is formed by the longitudinal axis of the connecting elements 4c to 4f substantially. Thus, in particular, the bristle bundles 10 provided on the right edge of the brush head segments 3b to 3d can move towards the underside of the brush head 1, provided that an excessive compressive force is applied by these bristle bundles 10 to the teeth to be brushed. The front brush head segment 5 and the foremost rod-shaped brush head segment 3a follow this pivoting movement of the distal rod-shaped brush head segment 3c. In addition, these two elements 3a, 5 can pivot about the connecting elements 4a, 4b, ie in a direction opposite to the pivoting movement of the other connecting elements 3b to 3d. This results in a relatively high flexibility, in particular on the brush head.

At the in FIG. 2 As shown, a meandering basic body consisting of the brush head segments 6, 3 and 5 and the connecting elements 4 arranged between them is formed from a hard component as a result. This meandering configuration results from the fact that the connecting elements 4 are each provided on alternately opposite longitudinal sides. This leads to an overlay the pivoting movement of individual brush head segments 3 transversely to the longitudinal axis 9 of the brush head. 1

This in FIG. 2 embodiment shown has only connecting elements 4, which are provided at the edge of the brush head 1.

In contrast, this has in FIG. 3 embodiment shown connecting elements 4, which are provided on the central longitudinal axis 9 of the brush head 1. The individual connecting elements 4 bear longitudinally extending bristle bundles 12, which bridge adjacent rod-shaped brush head segments 3 and cover the entire longitudinal extent of the connecting elements 4. Opposite in the Figures 1 and 2 The embodiments shown in FIG FIG. 3 embodiment shown not four, but three brush head segments 3, each carrying longitudinal rows of bristle bundles 10.

If, for example, the grip handle 2 near brush head segment 3c externally excessively applied on one side with a compressive force, for example, by a compressive force transmitted through the edge-side bristle bundle 10, so this brush head segment 3c pivots about the longitudinal axis of the connecting element 4. The pressure-loaded edge bristle bundle 10 is with its fastening side end pivoted to the back of the brush head 1. To the same extent opposite to the central longitudinal axis 9 of the brush head 1 bristle bundles 10 of the corresponding brush head segment 3 c are lifted out of the plane of the front of the brush head 1. The more distal provided brush head segments 3a, 3b and the front brush head segment 5 make this pivoting movement, as far as they are not or little burden. If the respective brush head segments 3a, 3b and 5 are loaded on their own, they react by an independent pivoting movement about the central longitudinal axis 9 of the brush head and thus adapt to the tomography of the surface to be cleaned.

In the FIGS. 1 to 3 is shown between adjacent brush head segments 3, 5, 6 each a transverse to the longitudinal axis 9 extending groove 13. This passes through the brush head 1 completely and extends over more than 85% of the width of the brush head 1. For reasons of hygiene, the groove 13 may be filled with a soft elastic plastic, such as a thermoplastic elastomer. Thus, the groove can be closed by a located in the region of the top or bottom of the brush head 1 and the groove 13 bridging membrane, which is also preferably made of a thermoplastic Elastomer is formed. Alternatively, the groove 13 may also be filled with a thermoplastic elastomer. The aforementioned measures serve to seal the groove 13 and prevent bacteria and / or contamination from settling in the groove 13.

This in FIG. 4 embodiment shown corresponds essentially to the embodiment according to FIG. 3 , with the difference that the brush head segments 3 do not extend at right angles to the central longitudinal axis 9 of the brush head, but are oriented obliquely forwardly. However, as in the case of the abovementioned brush head segments 3, a groove 13, which may be filled with a thermoplastic elastomer, extends in each case. In the longitudinal direction one behind the other web-shaped connecting elements 4 are provided which connect the individual axially successive brush head segments 3 together. At the in FIG. 5 The individual web-shaped connecting elements 4 allow a torsion and thus a pivotal movement of two at the same height laterally outgoing brush head segments 3 similar to the previously with reference to FIG. 3 described embodiment.

The front brush head segment 5 may be in the in FIG. 4 pivoting embodiment shown to the rear, ie pivot out of the protruded from the bristle bundles, preferably flat surface to the rear. Such a pivoting movement leads to a curvature of the central longitudinal axis at right angles to the plane of the drawing. The pivot axis of this pivoting movement is perpendicular to the central longitudinal axis 9 of the brush head 1 but in a plane substantially parallel to the surface of the brush head 1. In a torsion of the connecting element 4, for example, the brush head side brush head segments 3 results in a pivoting movement about the central longitudinal axis 9, which simultaneously Can be pivot axis for the corresponding pivoting movement. Depending on the material properties of the connecting element 4 and the outer, the brush head segments 3 forming material may additionally result in a pivoting movement about an axis which is substantially parallel to the central longitudinal axis 9, but adjacent thereto extends. The corresponding pivot axis can be done, for example, by an imaginary connecting line between the respective bottom of the grooves 13. This imaginary pivot axis is in FIG. 3 denoted by reference numeral 14.

At the in FIG. 5 shown embodiment, a pivoting movement about the imaginary pivot axis 14 is more pronounced. The brush head segments are connected to each other via joints 15. The joints 15 are created by free cutting of the brush head 1 almost to the longitudinal axis 9. This can result in substantially triangular brush head segments 3. These can pivot about a pivot axis, which is formed by the joint 15 and extends substantially parallel to the longitudinal axis 9 of the brush head 1, ie in particular at a compressive stress of the bristle bundles 10 from the surface of the Brush head are pivoted backwards. However, the opposing brush head segments 3 can also pivot about the web-shaped connecting element 4, ie in a plane which extends substantially perpendicular to the longitudinal axis 9 of the brush head 1. Such a torsion of the two brush head segments 3, for example, at a lateral compressive stress of the bristle bundles 10 leads to the lifting out of the opposite bristle bundles from the surface of the brush head. 1

The front brush head segment 5 behaves under compressive stress substantially as the brush head segment 5 of the embodiment according to FIG. 4 , In addition to a pivoting movement about a pivot axis which extends at right angles to the longitudinal axis 9 of the brush head 1 and in the plane thereof, a torsion, ie a rotational movement about the longitudinal axis 9 of the brush head 1 is possible. Of course, overlays of the two pivoting movements are conceivable. In the torsional movement about the central longitudinal axis 9 bristle bundles lying on one side of the longitudinal axis are downwards, ie pivoted away from the surface, whereas the bristle bundles 7 located on the opposite surface are lifted out. Instead of individual bristle bundles, a uniform bristle field with a plurality of bristle filaments can be provided on the front brush head segment.

That for the front brush head segment 5 of in FIG. 5 shown embodiment also applies to the front part of the brush head 1 of the embodiment according to FIG. 6 , The majority of the bristle bundles provided on the brush head 1 are connected to the handle 2 in this case in a relatively stiff manner. Only the front brush head segment 5 can pivot about the hinge 15 or be twisted in this.

Due to the torsional ability of the web-shaped connecting elements, the individual brush head segments 3 can in any case pivot about the central longitudinal axis 9 of the brush head 1. Single or all bar-shaped connecting elements 4 should preferably be designed so that a bending of the brush head 1 along the longitudinal axis 9 is possible, so that in the direction of the longitudinal axis 9, a curved contour of the brush head 1 can result under compressive stress. In this embodiment, further results in a complex deformation of the brush head 1 both by relative pivoting of individual brush head segments 3 relative to each other about the longitudinal axis 9 (torsion) as well as due to a deflection of the longitudinal axis 9, so that the individual bristle bundles 7, 8, 10, 11 best adapted to the contour to be cleaned in the oral cavity.
