A synthetic bristle (1, 1a) which is adapted to be inserted into the brush body (4) or the like while being bent in a U-shape and is prefabricated to have a spherical thickening (2) integral therewith at either end, characterized in that the spherical thickenings (2) at either end of the bristle are of different diameter.

Description

Die Erfindung betrifft eine Kunststoffborste, die U-förmig gebogen im Bürstenkörper od. dgl. einsetzbar ist und vorgefertigt an ihren beiden Enden einstückig mit einer kugeligen Verdickung versehen ist.The invention relates to a plastic bristle which can be used in a U-shaped manner in the brush body or the like and which is prefabricated and provided in one piece with a spherical thickening at its two ends.

Eine derartige Kunststoffborste ist aus der FR-A-2395 726 bekannt.Such a plastic bristle is known from FR-A-2395 726.

Ferner ist aus der DE-B-1083 781 eine Borste aus natürlichem oder synthetischem Werkstoff bekannt, die an einem Ende eine Verdickung in Form einer runden Polle oder eines Köpfchens aufweist.Furthermore, from DE-B-1083 781 a bristle made of natural or synthetic material is known, which has a thickening in the form of a round pollen or a head at one end.

Aus der CH-A- 401 903 ist eine Borste für eine Bürste bekannt, die aJMiVenigstens einem Ende eine gerundete Verbreiterung hat.A bristle for a brush is known from CH-A-401 903, which has a rounded widening at least at one end.

Sind an beiden Enden der Borsten kugelförmige Verdickungen vorgesehen, haben diese bei den vorerwähnten Vorveröffentlichungen gleiche Grösse und gleiche Form. Dies kann bei einer U-förmigen Anordnung der Borsten insbesondere mit unterschiedlich langen U-Schenkeln zu Platzschwierigkeiten führen, weil der längere U-Schenkel mit der Verdickung des kürzeren U-Schenkels kollidieren kann. Erst recht gilt dies dann, wenn beide kugeligen Verdickungen auf gleicher Höhe liegen und aneinanderstossen. Dadurch könnte die Wirkung der Borsten teilweise aufgehoben werden, weil der Eintritt einer Haarsträhne zwischen die beiden U-Schenkel erheblich erschwert ist.If spherical thickenings are provided at both ends of the bristles, they have the same size and shape in the aforementioned prior publications. With a U-shaped arrangement of the bristles, particularly with U-legs of different lengths, this can lead to space difficulties because the longer U-leg can collide with the thickening of the shorter U-leg. This is especially true when both spherical thickenings are at the same height and meet. This could partially cancel out the effect of the bristles, because the entry of a strand of hair between the two U-legs is considerably more difficult.

Würde man andererseits beide gleichgrossen Verdickungen entsprechend klein machen, wäre der zu erzielende Massageeffekt zumindest vermindert.If, on the other hand, one made both thickenings of the same size accordingly small, the massage effect to be achieved would at least be reduced.

Es besteht deshalb die Aufgabe, eine Kunststoffborste der eingangs erwähnten Art zu schaffen, die auch bei U-förmiger Anordnung eine gute Wirkung beider U-Schenkel unabhängig voneinander ermöglicht.The object is therefore to create a plastic bristle of the type mentioned at the outset which, even with a U-shaped arrangement, enables both U-legs to work well independently of one another.

Die Lösung dieser Aufgabe besteht darin, dass die kugeligen Verdickungen an den beiden Borstenenden einen verschiedenen Durchmesser haben. Somit kann eine relativ grosse kugelige Verdickung einen guten Massageeffekt haben, eine kleinere Verdickung immer noch verhindern, dass die Borste spitz und für das Haar oder die Kopfhaut ungünstig ist, dennoch kann aber eine Haarsträhne auch gut zwischen die beiden U-Schenkel einer U-förmig gebogenen Kunststoffborste eintreten.The solution to this problem is that the spherical thickenings at the two bristle ends have a different diameter. Thus, a relatively large spherical thickening can have a good massage effect, a smaller thickening can still prevent the bristle from being pointed and unfavorable to the hair or scalp, but a strand of hair can also be good between the two U-legs of a U-shaped Enter the curved plastic bristle.

Besonders zweckmässig ist es, wenn die Verdickungen der geometrischen Kugelform weitestgehend angenähert sind. Dadurch werden scharfe Kanten oder Übergänge insbesondere im Bereich des Übergangs von der eigentlichen Borste zu der kugeligen Verdickung, die haarschädigend sein könnten, vermieden.It is particularly expedient if the thickenings are as close as possible to the geometric spherical shape. This avoids sharp edges or transitions, in particular in the region of the transition from the actual bristle to the spherical thickening, which could damage the hair.

Der Durchmesser der Borste kann weitgehend beliebig sein. Zweckmässig ist es, wenn der Durchmesser 0,3 bis etwa 3 mm vorzugsweise etwa 1 bis 1,5 mm beträgt. Der Durchmesser der kugeligen Verdickung kann etwa das 1, 2 bis 3-fache, vorzugsweise etwa das doppelte des Borstendurchmessers betragen.The diameter of the bristle can largely be any. It is expedient if the diameter is 0.3 to about 3 mm, preferably about 1 to 1.5 mm. The diameter of the spherical thickening can be about 1.2 to 3 times, preferably about twice the bristle diameter.

In vorteilhafter Weise wird durch die vorliegende Erfindung eine Kunststoffborste geschaffen und zur Verfügung gestellt, die an ihren beiden Enden an die Kugelform weitestgehend angenäherte, jedoch verschieden grosse Verdickungen hat, so dass einerseits eine gute Massagefunktion an der Kopfhaut, andererseits aber auch eine gute Bürstfunktion innerhalb der Haare erzielt werden kann, wobei Haare und Haarsträhnen auch gut zwischen die beiden Schenkel einer U-förmig gebogenen Kunststoffborste eintreten können, obwohl an diesem Eintritt die kugeligen Verdickungen vorhanden sind.Advantageously, a plastic bristle is created and made available by the present invention, which at its two ends largely approximates the spherical shape, but has different thickenings, so that on the one hand a good massage function on the scalp, but on the other hand also a good brushing function within of hair can be achieved, hair and strands of hair can also enter well between the two legs of a U-shaped plastic bristle, although the spherical thickenings are present at this entry.

Nachstehend ist die Erfindung anhand der Zeichnung noch näher beschrieben. Es zeigt:

  • Fig. 1 eine Bürste mit an ihren Enden kugelförmige Verdickungen aufweisenden Borsten, wobei gleichzeitig dargestellt ist, dass die U-förmig angeordneten Borsten zwei gleich lange oder zwei verschieden lange Schenkel haben können,
  • Fig. 2 in vergrössertem Masstab eine Borste mit zwei kugeligeh Verdickungen, die unterschiedliche Durchmesser haben, vor der U-förmigen Verformung und Einfügung in einen Bürstenkörper,
  • Fig. 3 in schematisierter Darstellung einen Teilquerschnitt durch den Bereich einer Bohrung mit eingesetzter, U-förmig geformter Borste, die zwei gleich lange Schenkel hat, sowie
  • Fig. 4 eine der Fig. 3 entsprechende Darstellung, bei der die beiden U-Schenkel einer Borste verschieden lang sind.
The invention is described in more detail below with reference to the drawing. It shows:
  • 1 is a brush with bristles having spherical thickenings at their ends, it being shown at the same time that the U-shaped bristles can have two legs of the same length or two legs of different lengths,
  • 2 on an enlarged scale a bristle with two spherical thickenings, which have different diameters, before the U-shaped deformation and insertion into a brush body,
  • Fig. 3 is a schematic representation of a partial cross section through the area of a bore with inserted, U-shaped bristle, which has two legs of equal length, and
  • Fig. 4 is a representation corresponding to Fig. 3, in which the two U-legs of a bristle are of different lengths.

Eine in Fig. 2 vergrössert und deutlich dargestellte Kunststoffborste 1 ist an ihren beiden Enden jeweils mit einer kugeligen Verdickung 2 versehen. Die Borste 1 kann entsprechend den Figuren 3 und 4 U-förmig gebogen in Bohrungen 3 eines Bürstenkörpers 4 eingesetzt und dort in bekannter Weise befestigt werden. Gegebenenfalls können auch mehrere solche Borsten 1 in eine Bohrung 3 eingefügt werden, wenn ein grösseres Borstenbüschel erwünscht ist.A plastic bristle 1, enlarged and clearly shown in FIG. 2, is provided with a spherical thickening 2 at each of its two ends. 3 and 4, the bristle 1 can be used in a U-shaped manner in bores 3 of a brush body 4 and fastened there in a known manner. If necessary, a plurality of such bristles 1 can also be inserted into a bore 3 if a larger tuft of bristles is desired.

In Fig. 1 ist an einer Bürste 5 mit Handgriff 6 angedeutet, dass alle kugelförmigen Verdickungen 2 auf gleicher Höhe liegen können, was der Anordnung in Fig. 3 entspricht, oder dass die Verdickungen 2 in unterschiedlichen Höhen angeordnet sein können, wenn die Borsten 1 gemäss Fig. 5 gebogen und eingesetzt sind.In FIG. 1, a brush 5 with a handle 6 indicates that all spherical thickenings 2 can be at the same height, which corresponds to the arrangement in FIG. 3, or that the thickenings 2 can be arranged at different heights when the bristles 1 5 are bent and inserted.

In Fig. 2 erkennt man deutlich, dass die beiden Verdickungen 2 an den beiden Enden der Borste 1 unterschiedlich dick sind, wobei angedeutet ist, dass diese Verdickungen 2 einerseits etwa den 1,2-fachen Durchmesser, andererseits eventuell sogar den 3-fachen Durchmesser des Borstendurchmessers haben können.2 clearly shows that the two thickenings 2 at the two ends of the bristle 1 are of different thicknesses, whereby it is indicated that these thickenings 2 on the one hand about 1.2 times the diameter, on the other hand possibly even 3 times the diameter of the bristle diameter.

In Fig. 2 ist ausserdem verdeutlicht, dass aufgrund der vorgefertigten Anordnung und Ausbildung der Verdickungen 2 an den beiden Enden der Borste 1 scharfe Kanten an den Borstenenden vermieden sind.2 also shows that, due to the prefabricated arrangement and configuration of the thickenings 2 at the two ends of the bristle 1, sharp edges at the bristle ends are avoided.

Die Bürste 5 eignet sich aufgrund der grossen Zahl von Verdickungen 2 und der Herstellung der Borsten aus Kunststoff besonders gut als Fönbürste, da die Haare und Haarsträhnen entsprechend gut geteilt und gelockert werden, um die Warmluft eindringen zu lassen, ohne dass die Borsten sich in haarschädigender Weise erhitzen. Es bleibt zwischen den beiden U-Schenkeln auch im Bereich der Verdickungen 2 ein genügender Abstand, um die Haare und Haarsträhnen zu teilen und auch zwischen die beiden Schenkel einer Borste 2 eintreten zu lassen.The brush 5 is suitable due to the large number of thickenings 2 and the manufacture of the Plastic bristles are particularly good as hair dryer brushes, since the hair and strands of hair are correspondingly well divided and loosened in order to allow the warm air to penetrate without the bristles heating up in a way that damages the hair. There is a sufficient distance between the two U-legs, also in the area of the thickenings 2, in order to divide the hair and strands of hair and also to allow a bristle 2 to enter between the two legs.
