Definitions
- the invention relates to a plastic bristle with a thickened end which can be used in a U-shaped manner in the brush body or the like.
- Such plastic bristles are already known. They are usually used in the brush body and in the holes there that they deform into a U-shape, whereby two ends of different lengths can or should be formed. Thereafter, in a known brush, the longer protruding ends are compressed under the influence of heat in order to to get the thickening. If both U-legs of the curved bristle were the same length, they would be fused together in this process and could therefore no longer move freely, as is desirable with the usual bristle thickness in such cases. In addition, a user's hair could get caught between such fused bristle parts. Thus, only half of the existing bristles can have the desired thickening in these known brushes.
- the invention is therefore based on the object to provide a plastic bristle of the type mentioned which, without the risk of connecting the two bristle ends with their U-shaped deformation, permits an increase in the number of thickenings on the brush, so that this brush is particularly good is suitable as a hairbrush. This should avoid sharp edges and tips at the bristle ends, which could be damaging to the hair when using the brush.
- the solution to this problem consists essentially in that the bristle is prefabricated in one piece with a spherical thickening at both ends.
- the prefabrication makes it possible for the thickenings to approximate the geometric spherical shape as far as possible. This prevents mushroom-shaped thickening with sharp edges.
- the spherical thickenings at the two bristle ends can have the same or a different diameter.
- the bristle diameter can be largely arbitrary and be about 0.3 to 3 mm; the bristle diameter is expediently about 1 to 1.5 mm.
- the ball diameter is expediently 1.2 to 3 times the bristle diameter, preferably about double.
- a plastic bristle is created and made available by the present invention, in which there are largely thickened portions at both ends of the spherical shape, so that a brush made therewith has significantly more spherical heads that can perform a correspondingly good massage function.
- a brush made therewith has significantly more spherical heads that can perform a correspondingly good massage function.
- easy and hair-friendly use is also possible on the underside of the thickening facing the bristles.
- a plastic bristle 1 (Fig. 3) or 1 a (Fig. 2) is provided according to the invention with a spherical thickening 2 at both ends.
- This bristle 1 or 1 a can, according to FIGS. 4 and 5, be bent into a U-shape in bores 3 of a brush body 4 and be fastened there in a known manner. If necessary, several such bristles 1, 1 a can also be inserted into a bore 3 if a larger tuft of bristles is desired.
- Fig. 1 is indicated on a brush 5 with a handle 6 that all ball heads 2 can be at the same height, which corresponds to the arrangement of Fig. 4, or that the ball heads 2 can have different heights if the bristles 1 or 1a according Fig. 5 are used.
- both ball heads 2 are of the same thickness and have approximately twice the diameter as the bristle 1 itself.
- the ball heads 2 can have different thicknesses at the two ends, whereby it is also indicated that that these ball heads 2 can only have about 1.2 times the diameter, but also possibly even 3 times the diameter of the bristle diameter.
- the ball heads 2 of the bristle 1 in FIG. 3 could also be smaller or larger.
- the brush according to the invention is particularly well suited as a hair dryer brush, 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 becoming damaging to the hair Heat way.

Abstract
Description
Die Erfindung betrifft eine Kunststoffborste mit verdicktem Ende, die U-förmig gebogen in Bürstenkörper od. dgl. einsetzbar ist.The invention relates to a plastic bristle with a thickened end which can be used in a U-shaped manner in the brush body or the like.
Derartige Kunststoffborsten sind bereits bekannt. Sie werden in der Regel so in den Bürstenkörper und in dort vorhandene Bohrungen eingesetzt, daß sie sich U-förmig verformen, wobei sich zwei unterschiedlich lange Enden bilden können oder sollen.Danach werden bei einer bekannten Bürste die länger vorstehenden Enden unter Hitzeeinwirkung angestaucht, um die Verdickung zu erhalten. Wären beide U-Schenkel der gebogenen Borste gleich lang, würden sie bei diesem Verfahren miteinander verschmolzen und könnten sich somit nicht mehr frei bewegen, wie es an sich bei der in solchen Fällen üblichen Borstendicke erwünscht ist. Darüber hinaus könnten sich zwischen solchen verschmolzenen Borstenteilen die Haare eines Benutzers verfangen. Somit kann bei diesen bekannten Bürsten immer nur die Hälfte der vorhandenen Borsten die erwünschte Verdickung haben. Dabei ergeben sich beim Anstauchen der an der Bürste befindlichen Borsten insbesondere an der dem Bürstenkörper zugewandten Unterseite flache Verdickungen, so daß eine abgerundete Form allenfalls an der entgegengesetzten Oberfläche erreichbar ist. Diese flachen Unterseiten führen dazu, daß am Übergang zur Oberseite relativ scharfe Ränder entstehen. Diese können bei der Benutzung der Bürste als Fönbürste zu Haarschädigungen und zu einem schlechten Gleiten innerhalb der Haarsträhne führen. Darüber hinaus bleiben die nicht angestauchten Borstenenden scharfkantig und somit ebenfalls haarschädigend, da diese Enden Ausfransungen haben, die bei dem Ablängen der Kunststoffborsten entstehen.Such plastic bristles are already known. They are usually used in the brush body and in the holes there that they deform into a U-shape, whereby two ends of different lengths can or should be formed. Thereafter, in a known brush, the longer protruding ends are compressed under the influence of heat in order to to get the thickening. If both U-legs of the curved bristle were the same length, they would be fused together in this process and could therefore no longer move freely, as is desirable with the usual bristle thickness in such cases. In addition, a user's hair could get caught between such fused bristle parts. Thus, only half of the existing bristles can have the desired thickening in these known brushes. When the bristles located on the brush are compressed, this results in particular on the underside facing the brush body flat thickening, so that a rounded shape can only be reached on the opposite surface. These flat undersides result in relatively sharp edges at the transition to the top. These can lead to hair damage and poor sliding within the strand of hair when using the brush as a hair dryer brush. In addition, the bristle ends that are not upset remain sharp-edged and therefore also hair-damaging, since these ends have fraying that occur when the plastic bristles are cut to length.
Der Erfindung liegt deshalb die Aufgabe zugrunde, eine Kunststoffborste der eingangs erwähnten Art.zu schaffen, die ohne die Gefahr einer Verbindung der beiden Borstenenden bei deren U-förmiger Verformung eine Vergrößerung der Anzahl der Verdickungen an der Bürste erlaubt, so daß diese Bürste besonders gut als Fönbürste geeignet ist. Dabei sollen scharfe Kanten und Spitzen an den Borstenenden vermieden werden, die bei der Benutzung der Bürste haarschädigend sein könnten.The invention is therefore based on the object to provide a plastic bristle of the type mentioned which, without the risk of connecting the two bristle ends with their U-shaped deformation, permits an increase in the number of thickenings on the brush, so that this brush is particularly good is suitable as a hairbrush. This should avoid sharp edges and tips at the bristle ends, which could be damaging to the hair when using the brush.
Die Lösung dieser Aufgabe besteht im wesentlichen darin, daß die Borste vorgefertigt an beiden Enden einstückig mit einer kugeligen Verdickung versehen ist. Dadurch ist die Borste besonders geeignet, in Bürsten eingesetzt zu werden, die zusammen mit einem Fön benutzt werden, da entsprechend viele Kugeln und Verdickungen vorhanden sind, um die Haare zu teilen und zu trennen und die Warmluft hinzutreten zu lassen. Da die Borste aus Kunststoff besteht, wird sie dennoch von der Fön-Warmluft nicht in haarschädigender Weise aufgeheizt. Selbst wenn beide Enden der U-förmig gebogenen und in die Bürste eingesetzten Borste gleich lang sind, wird vermieden, daß die Borstenenden zusammengeschmolzen werden. Scharfe Kanten und Spitzen sind vermieden.The solution to this problem consists essentially in that the bristle is prefabricated in one piece with a spherical thickening at both ends. This makes the bristle particularly suitable for use in brushes that are used together with a hair dryer, since there are many balls and thickenings to separate and separate the hair and allow the warm air to enter. Since the bristle is made of plastic, it is not heated in a hair-damaging manner by the hot air from the hair dryer. Even if both ends of the U-shaped bristle and the bristle inserted into the brush have the same length, it is avoided that the bristle ends are melted together. Sharp edges and tips are avoided.
Durch die Vorfertigung ist es möglich, daß die Verdickungen der geometrischen Kugelform weitestgehend angenähert sind. Somit werden pilzförmige Verdickungen mit scharfen Rändern vermieden.The prefabrication makes it possible for the thickenings to approximate the geometric spherical shape as far as possible. This prevents mushroom-shaped thickening with sharp edges.
Zur Anpassung an unterschiedliche Zwecke können die kugeligen Verdickungen an den beiden Borstenenden denselben oder einen verschiedenen Durchmesser haben.To adapt to different purposes, the spherical thickenings at the two bristle ends can have the same or a different diameter.
Der Borstendurchmesser kann weitgehend beliebig sein und etwa 0,3 bis 3 mm betragen; dabei liegt der Borstendurchmesser zweckmäßigerweise bei etwa 1 bis 1,5 mm. Der Kugeldurchmesser beträgt zweckmäßigerweise das 1,2 bis 3-fache des Borstendurchmessers, bevorzugt etwa das.Doppelte.The bristle diameter can be largely arbitrary and be about 0.3 to 3 mm; the bristle diameter is expediently about 1 to 1.5 mm. The ball diameter is expediently 1.2 to 3 times the bristle diameter, preferably about double.
In vorteilhafter Weise wird durch die vorliegende Erfindung eine Kunststoffborste geschaffen und zur Verfügung gestellt, bei der an beiden Enden an die Kugelform weitestgehend angenäherte Verdickungen vorhanden sind, so daß eine damit gefertigte Bürste wesentlich mehr Kugelköpfe aufweist, die eine entsprechend gute Massagefunktion ausüben können. Gleichzeitig ist aufgrund der kugeligen Form auch an der den Borsten zugewandten Unterseite der Verdickung eine leichte und haarschonende Benutzung möglich.Advantageously, a plastic bristle is created and made available by the present invention, in which there are largely thickened portions at both ends of the spherical shape, so that a brush made therewith has significantly more spherical heads that can perform a correspondingly good massage function. At the same time, due to the spherical shape, easy and hair-friendly use is also possible on the underside of the thickening facing the bristles.
Nachstehend ist die Erfindung mit ihren ihr als wesentlich zugehörenden Einzelheiten anhand der Zeichnung noch näher beschrieben. Es zeigt in zum Teil schematisierter Darstellung:
- Fig. 1 eine Bürste mit erfindungsgemäßen Borsten, wobei gleichzeitig dargestellt ist, daß die U-förmig angeordneten Borsten zwei gleich lange oder zwei verschieden lange Enden haben können,
- Fig. 2 in vergrößertem Maßstab eine Borste mit zwei kugeligen Verdickungen, die unterschiedliche Durchmesser haben,
- Fig. 3 eine Borste mit zwei gleich dicken Kugelköpfen,
- Fig. 4 einen Teilquerschnitt durch den Bereich einer Bohrung mit eingesetzter, U-förmig geformter Borste, die zwei gleich lange Schenkel hat, sowie
- Fig. 5 eine der Fig. 4 entsprechende Darstellung, bei der die beiden U-Schenkel einer Borste verschieden lang sind.
- 1 shows a brush with bristles according to the invention, it being shown at the same time that the U-shaped bristles can have two ends of the same length or two ends of different lengths,
- 2 on an enlarged scale a bristle with two spherical thickenings that have different diameters,
- 3 shows a bristle with two equally thick spherical heads,
- Fig. 4 shows a partial cross section through the area of a bore with an inserted, U-shaped bristle, which has two legs of equal length, and
- Fig. 5 is a representation corresponding to Fig. 4, in which the two U-legs of a bristle are of different lengths.
Eine Kunststoffborste 1 (Fig. 3) bzw. 1 a (Fig. 2) ist erfindungsgemäß an ihren beiden Enden jeweils mit einer kugeligen Verdickung 2 versehen. Diese Borste 1 oder 1 a kann entsprechend den Figuren 4 und 5 U-förmig gebogen in Bohrungen 3 eines Bürstenkörpers 4 eingesetzt und dort in bekannter Weise befestigt werden. Gegebenenfalls können auch mehrere solche Borsten 1, 1 a in eine Bohrung 3 eingefügt werden, wenn ein größerer Borstenbüschel erwünscht ist.A plastic bristle 1 (Fig. 3) or 1 a (Fig. 2) is provided according to the invention with a
In Fig. 1 ist an einer Bürste 5 mit Handgriff 6 angedeutet, daß alle Kugelköpfe 2 auf gleicher Höhe liegen können, was der Anordnung der Fig. 4 entspricht, oder daß die Kugelköpfe 2 unterschiedliche Höhen haben können, wenn die Borsten 1 oder 1a gemäß Fig. 5 eingesetzt sind.In Fig. 1 is indicated on a brush 5 with a handle 6 that all
Im Ausführungsbeispiel nach Fig. 3 sind beide Kugelköpfe 2 gleich dick und haben dabei etwa den doppelten Durchmesser wie die Borste 1 selbst. In Fig. 2 ist angedeutet, daß die Kugelköpfe 2 an den beiden Enden unterschiedlich dick sein können, wobei gleichzeitig angedeutet ist, daß diese Kugelköpfe 2 auch nur den etwa 1,2-fachen Durchmesser, aber auch eventuell sogar den 3-fachen Durchmesser des Borstendurchmessers haben können. In gleicher Weise könnten die Kugelköpfe 2 der Borste 1 in Fig. 3 auch kleiner oder größer sein.In the exemplary embodiment according to FIG. 3, both
Man erkennt vor allem in diesen Figuren 2 und 3 deutlich, daß aufgrund der vorgefertigten Anordnung der Verdickungen 2 an den beiden Enden der Borsten 1 und 1a scharfe Kanten an den Borstenenden vermieden sind. Darüber hinaus ist die Zahl der massierenden Verdickungen an der Bürste 5 gegenüber den bisherigen Ausführungen, bei denen nur ein längeres Ende der U-förmig gebogenen Borsten verdickt ist, praktisch verdoppelt. Dadurch läßt sich entweder die Gesamtzahl der verwendeten Borsten reduzieren, oder es ergibt sich insgesamt eine größere Zahl wirksamer Kugelköpfe. Die vorgefertigte Anbringung der Verdickungen erlaubt dabei eine sorgfältigere Ausbildung der einzelnen Kugelköpfe, die bei einem Anstauchen an die Borsten einer schon gestopften Bürste kaum erreichbar ist.It can be seen particularly clearly in these FIGS. 2 and 3 that, due to the prefabricated arrangement of the
Die erfindungsgemäße Bürste 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.Due to the large number of
Alle in der Beschreibung, den Ansprüchen und der Zeichnung dargestellten Merkmale und Konstruktionsdetails können sowohl einzeln als auch in beliebiger Kombination miteinander wesentliche Bedeutung haben.All features and construction details shown in the description, the claims and the drawing can have significant meaning both individually and in any combination with one another.
