Description

Die Erfindung betrifft einen Pinsel mit einem Griff, einer Borstenträgerplatte, die unmittelbar am Griff befestigt ist, und einer Vielzahl von Borstenbündeln, die durch Aufnahmeöffnungen in der Borstenträgerplatte durchgesteckt sind.The invention relates to a brush with a handle, a bristle carrier plate which is attached directly to the handle, and a plurality of bristle bundles, which are inserted through receiving openings in the bristle carrier plate.

Das größte Problem bei der Herstellung von Pinseln besteht darin, die Borsten zu befestigen. Dabei muss zum einen eine ausreichend hohe Anzahl von Borsten befestigt werden können, um die gewünschte Dichte des aus den Borsten gebildeten Borstenpaketes zu erhalten. Zum anderen muss gewährleistet sein, dass die Borsten zuverlässig befestigt sind, so dass sie bei der Benutzung nicht herausfallen.The biggest problem with making paintbrushes is fixing the bristles. In this case, on the one hand, a sufficiently high number of bristles must be able to be fastened in order to obtain the desired density of the bristle pack formed from the bristles. On the other hand, it must be ensured that the bristles are reliably fixed so that they do not fall out during use.

Eine Befestigungsart besteht darin, die Borsten als dichtes Paket in eine Hülse einzustecken und die in der Hülse angeordneten Enden der Borsten miteinander zu verkleben, beispielsweise durch Kunstharz. Anschließend wird der Griff des Pinsels mit der Hülse verbunden. Bei dieser Art von Befestigung kann zwar ein sehr dichtes Borstenpaket erhalten werden. Allerdings sind die einzelnen Borsten nicht besonders zuverlässig gehalten. Eine andere Art von Befestigung besteht darin, die Borsten mittels kleiner Klammern in Löchern zu befestigen, beispielsweise in einem Holzkörper. Es ist bei dieser Befestigungsart zwar grundsätzlich möglich, die Borsten vergleichsweise gut zu befestigen. Allerdings müssen die zur Aufnahme der Borsten verwendeten Löcher einen vergleichsweise großen Abstand voneinander haben, da ansonsten der die Löcher enthaltende Körper keine ausreichende Festigkeit hat, um die Klammern zu halten. Der notwendige Abstand der Löcher voneinander führt dazu, dass das Borstenpaket nicht besonders dicht ist. Dieses Problem wird noch gravierender, wenn als Borsten Naturborsten verwendet werden, beispielsweise Schweinshaare. Während bei beispielsweise synthetischen Borsten die Klammer in der Mitte der U-förmig gebogenen Borsten angeordnet werden kann und beide Enden der Borste genutzt werden können, kann bei Borsten aus Schweinshaar nur ein Ende benutzt werden, nämlich das von der Haarwurzel entgegengesetzte Ende. Hieraus folgt, dass die Borsten länger ausgeführt werden müssen als das eigentliche Borstenpaket, da der im Inneren des Pinsels liegende Endabschnitt umgebogen wird, um von der Klammer befestigt werden zu können. Dies ist hinsichtlich der Kosten nachteilig, da Naturborsten besonders teuer sind. Außerdem ergibt sich eine sehr geringe Dichte des Borstenpakets.
Aus der WO 88/02998 A1 ist ein Pinsel bekannt, der zwei Reihen von Borsten enthält. Diese sind in Blöcken angeordnet, und zwar innerhalb von Öffnungen.
One method of attachment is to insert the bristles as a dense package into a sleeve and to glue the ends of the bristles disposed in the sleeve together, for example by synthetic resin. Subsequently, the handle of the brush is connected to the sleeve. In this type of attachment, although a very dense bristle package can be obtained. However, the individual bristles are not kept very reliable. Another type of attachment is to fix the bristles by means of small brackets in holes, for example in a wooden body. Although it is in principle possible with this type of attachment to fasten the bristles comparatively well. However, the holes used to receive the bristles need to be a relatively large distance apart, otherwise the body containing the holes will not have sufficient strength to hold the staples. The necessary distance of the holes from each other causes the bristle package is not very dense. This problem is even more serious when used as bristles natural bristles, such as pig hair. While in synthetic bristles, for example, the staple can be placed in the middle of the U-shaped bristles and both ends of the bristle can be used, in pig hair bristles only one end can be used, namely the opposite end of the hair root. It follows that the bristles must be made longer than the actual bristle package, since the lying inside the brush end portion is bent to be able to be attached by the clip can. This is disadvantageous in terms of cost, since natural bristles are particularly expensive. In addition, there is a very low density of the bristle package.
From the WO 88/02998 A1 a brush is known that contains two rows of bristles. These are arranged in blocks, within openings.

In US 1,482,415 A ist ein Pinsel gezeigt, der eine Führungsplatte aufweist, die zur Führung von Borsten dient.In US 1,482,415 A a brush is shown which has a guide plate which serves to guide bristles.

Die Aufgabe der Erfindung besteht darin, einen Pinsel zu schaffen, der sich durch geringe Herstellungskosten, ein dichtes Borstenpaket und eine zuverlässige Befestigung der einzelnen Borsten auszeichnet.The object of the invention is to provide a brush which is characterized by low production costs, a dense bristle package and a reliable attachment of the individual bristles.

Zur Lösung dieser Aufgabe ist erfindungsgemäß bei einem Pinsel der eingangs genannten Art vorgesehen, dass die Borstenträgerplatte ein Gitter ist und die Borsten eines Borstenbündels an ihren durch die Aufnahmeöffnungen durchgesteckten Enden mit der Borstenträgerplatte verbunden sind. Ein Gitter zeichnet sich dadurch aus, dass der Anteil der Aufnahmeöffnungen im Verhältnis zur Gesamtfläche sehr groß ist, insbesondere größer als 50 Prozent. Auf diese Weise ergibt sich eine besonders hohe Dichte des Borstenpaketes. Außerdem ergeben sich weitere Vorteile. Zum einen wird das gesamte Borstenpaket in mehrere kleinere Borstenbündel unterteilt, was die Befestigung der Borsten erleichtert. Zum anderen kann aufgrund des Durchsteckens der Borstenbündel durch die Aufnahmeöffnungen auf Klammern verzichtet werden, wodurch die Aufnahmeöffnungen vergleichsweise groß ausgeführt werden können. Dadurch ergibt sich ein dichtes Borstenpaket.To achieve this object is inventively provided in a brush of the type mentioned above, that the bristle carrier plate is a grid and the bristles of a bristle bundle are connected at their plugged through the receiving openings ends with the bristle carrier plate. A grid is characterized in that the proportion of the receiving openings in relation to the total area is very large, in particular greater than 50 percent. In this way, a particularly high density of the bristle package results. In addition, there are other benefits. First, the entire bristle package is divided into several smaller bristle bundles, which facilitates the attachment of the bristles. On the other hand, can be dispensed with due to the penetration of the bristle bundles through the receiving openings on brackets, whereby the receiving openings can be made comparatively large. This results in a dense bristle package.

Gemäß einer Ausführungsform ist der Griff mit einer Aufnahme versehen, in welche die Borstenträgerplatte eingesetzt ist. Dies führt zu einer besonders stabilen Verbindung zwischen der Borstenträgerplatte und dem Griff und außerdem zu einer ansprechenden Optik. Außerdem kann die Aufnahme so tief ausgeführt sein, dass die Ränder der Aufnahme das Borstenpaket abstützen.According to one embodiment, the handle is provided with a receptacle into which the bristle carrier plate is inserted. This leads to a particularly stable connection between the bristle carrier plate and the handle and also to an attractive appearance. In addition, the receptacle can be made so deep that the edges of the receptacle support the bristle package.

Gemäß einer alternativen Ausführungsform ist vorgesehen, dass die Borstenträgerplatte auf ihrer dem Griff zugewandten Seite mit einem umlaufenden Bund versehen ist. Dies ermöglicht, den Griff in den Bund einzusetzen, wodurch dieser mit geringem Aufwand mechanisch stabil mit der Borstenträgerplatte verbunden werden kann. Der Griff kann mit der Borstenträgerplatte verklebt werden oder mechanisch an dieser befestigt werden, beispielsweise durch Nägel, eine Schnappverbindung, eine Schraubverbindung, eine Schweißverbindung, etc. Ein weiterer Vorteil des umlaufenden Bundes besteht darin, dass ein sauberer Abschluss des Bereichs gegeben ist, in welchem die Borstenbündel mit der Borstenträgerplatte verbunden werden und auch der Griff mit der Borstenträgerplatte verbunden wird.According to an alternative embodiment it is provided that the bristle carrier plate is provided on its side facing the handle with a circumferential collar. This makes it possible to use the handle in the collar, which can be mechanically stable connected to the bristle carrier plate with little effort. The handle can be glued to the bristle carrier plate or mechanically attached to this, for example by nails, a snap connection, a screw connection, a welded connection, etc. Another advantage of the circulating collar is that a clean completion of the area is given, in which the bristle bundles with the bristle carrier plate be connected and the handle is connected to the bristle carrier plate.

Alternativ kann der Griff auch an die Borstenträgerplatte angespritzt werden, also innerhalb des Bundes oder auch die Borstenträgerplatte außen umgreifend.Alternatively, the handle can also be molded onto the bristle carrier plate, ie encompassing outside within the federal government or else the bristle carrier plate.

Gemäß einer Ausführungsform ist vorgesehen, dass die Borstenträgerplatte in eine Hülse eingefasst ist, die auch die Verbindung mit dem Stiel bewirkt. Die Hülse übernimmt die Funktion des Bundes. Der Vorteil dieser Ausführungsform besteht darin, dass die Borstenträgerplatte besser für das Einstecken der Borstenbündel erreichbar ist. Die Hülse kann aus Blech bestehen, so dass der Pinsel optisch einem traditionellen Pinsel sehr ähnlich sieht.According to one embodiment, it is provided that the bristle carrier plate is enclosed in a sleeve, which also causes the connection with the stem. The sleeve assumes the function of the federal government. The advantage of this embodiment is that the bristle carrier plate is better accessible for the insertion of the bristle bundles. The sleeve can be made of sheet metal, so that the brush visually looks very similar to a traditional brush.

Vorzugsweise ist vorgesehen, dass die Borstenträgerplatte auf ihrer den Borsten zugewandten Seite mit einem umlaufenden Bund versehen ist. Dieser stützt das Borstenpaket ab, so dass die Borsten gut zusammengehalten werden. Der Bund kann dabei entweder parallele Wände aufweisen oder Wände, die von der Borstenträgerplatte weg aufeinander zulaufen.It is preferably provided that the bristle carrier plate is provided on its side facing the bristles with a circumferential collar. This supports the bristle package, so that the bristles are held together well. The collar can have either parallel walls or walls that run away from each other from the bristle carrier plate.

In Abhängigkeit vom gewünschten Verwendungszweck kann die Borstenträgerplatte eben sein oder auch gewölbt. Dies ist insbesondere im Hinblick auf die Steifigkeit vorteilhaft.Depending on the intended use, the bristle carrier plate may be flat or arched. This is particularly advantageous in terms of stiffness.

Die Dichte des Borstenpaketes kann auch dadurch beeinflusst werden, wie die Borstenbündel in der Borstenträgerplatte angeordnet sind. Beispielsweise kann mindestens eines der Borstenbündel in einer Richtung angeordnet werden, die nicht senkrecht auf der Borstenträgerplatte steht. Beispielsweise können die außenliegenden Reihen der Borstenbündel zur Mitte des Borstenpaketes geneigt sein. So kann eine höhere Dichte der Borsten in den Bereichen erhalten werden, in denen dies vorteilhaft ist, oder es kann eine verbesserte Kapillarwirkung der Borsten erhalten werden.The density of the bristle pack can also be influenced by how the bristle bundles are arranged in the bristle carrier plate. For example, at least one of the bristle bundles can be arranged in a direction that is not perpendicular to the bristle carrier plate. For example, the outer rows of bristle bundles may be inclined to the center of the bristle pack. Thus, a higher density of the bristles can be obtained in the ranges in which this is advantageous, or an improved capillary action of the bristles can be obtained.

Die Dichte des Borstenpaketes kann auch dadurch variiert werden, dass die Flächenanteile der Aufnahmeöffnungen sich in verschiedenen Abschnitten der Borstenträgerplatte voneinander unterscheiden. Durch die Verwendung von beispielsweise kleineren Aufnahmeöffnungen im Außenbereich, die von entsprechend breiteren Stegen umgeben sind, kann im Außenbereich eines Borstenpaketes eine geringere Dichte erreicht werden als in der Mitte, wo beispielsweise größere Aufnahmeöffnungen verwendet werden können, die von dünneren Stegen umgeben sind. Auf diese Weise können auch an geeigneten Stellen an der Basis des Borstenpakets, also in der Nähe der Borstenträgerplatte, kleine Leerräume gebildet werden, die als "Vorratsraum" für Farbe dienen. Durch geeignete Anordnung und Dimensionierung dieser Vorratsräume wird beeinflusst, wie viel Farbe und wie gleichmäßig die Farbe beim Streichen zu den Borstenspitzen gelangt.The density of the bristle pack can also be varied by the fact that the surface portions of the receiving openings differ from one another in different sections of the bristle carrier plate. By using, for example, smaller receiving openings in the outer area, which are surrounded by correspondingly wider webs, a lower density can be achieved in the outer region of a bristle package than in the middle, where, for example larger receiving openings can be used, which are surrounded by thinner webs. In this way, even at suitable locations at the base of the bristle package, ie in the vicinity of the bristle carrier plate, small voids can be formed, which serve as a "storage space" for color. By appropriate arrangement and dimensioning of these storerooms, it is influenced how much color and how evenly the paint reaches the bristle tips when brushing.

Die Borsten eines Borstenbündels sind vorzugsweise an ihren durch die Aufnahmeöffnungen durchgesteckten Enden miteinander verbunden. Dies gewährleistet, dass sich keine Borsten aus einem Borstenbündel lösen.The bristles of a bundle of bristles are preferably connected to one another at their ends inserted through the receiving openings. This ensures that no bristles dissolve out of a bundle of bristles.

Die durch die Aufnahmeöffnungen durchgesteckten Enden der Borsten eines Borstenbündels können beispielsweise miteinander verschweißt sein. Dies ist besonders vorteilhaft, wenn Borsten aus einem Kunststoffmaterial verwendet werden. Beispielsweise können die Enden der Borsten gegen einen erwärmten Schmelzstempel gedrückt werden, so dass sie aufschmelzen und miteinander verschweißen. Gleichzeitig kann, falls dies gewünscht ist, durch geeignete Ausgestaltung des Schmelzstempels und geeignete Auswahl des Drucks auch die entsprechende Seite der Borstenträgerplatte aufgeschmolzen werden, so dass die Enden der Borstenbündel auch mit der Borstenträgerplatte verschweißt werden. Gegebenenfalls kann nach dem Verschmelzen der Borsten mit einem zweiten Stempel in die geschmolzenen Borsten nachgedrückt werden, um die Oberfläche zu bearbeiten oder um eine bessere Dichte zu bekommen.The inserted through the receiving openings ends of the bristles of a bristle bundle, for example, be welded together. This is particularly advantageous when bristles made of a plastic material are used. For example, the ends of the bristles may be pressed against a heated die so that they melt and weld together. At the same time, if desired, the appropriate side of the bristle carrier plate can be melted by suitable design of the melt die and suitable selection of the pressure, so that the ends of the bristle bundles are also welded to the bristle carrier plate. Optionally, after fusing the bristles with a second punch, they may be forced into the molten bristles to process the surface or to obtain a better density.

Alternativ kann vorgesehen sein, dass die Borsten eines Borstenbündels an ihren durch die Aufnahmeöffnungen durchgesteckten Enden miteinander verklebt sind, beispielsweise mittels eines Kunstharzes. Dies ist besonders dann vorteilhaft, wenn Borsten aus einem Material verwendet werden, das sich für ein Verschweißen nicht eignet. Mittels des Klebstoffs können die Borstenbündel auch gleich mit der Borstenträgerplatte verbunden werden.Alternatively, it can be provided that the bristles of a bristle bundle are glued together at their ends inserted through the receiving openings, for example by means of a synthetic resin. This is particularly advantageous when bristles are used of a material that is not suitable for welding. By means of the adhesive, the bristle bundles can also be connected to the bristle carrier plate at the same time.

Um den Pinsel optimal an den jeweiligen Verwendungszweck anzupassen, kann vorgesehen sein, dass die Borstenträgerplatte mit unterschiedlichen Borsten bestückt ist. Ein Beispiel einer solchen Bestückung besteht darin, die an der Außenseite der Borstenträgerplatte angeordneten Aufnahmeöffnungen mit besonders verschleißfesten Borsten zu bestücken und die in der Mitte der Borstenträgerplatte angeordneten Aufnahmeöffnungen mit besonders farbaufnahmefähigen Borsten zu bestücken.In order to adapt the brush optimally to the respective intended use, it can be provided that the bristle carrier plate is equipped with different bristles. An example of such equipment is to equip the receiving openings arranged on the outside of the bristle carrier plate with particularly wear-resistant bristles and those in the middle of the bristle carrier plate arranged receiving openings to stock with particularly color-receptive bristles.

Es ist auch möglich, innerhalb einer Aufnahmeöffnung unterschiedliche Borsten anzuordnen, beispielsweise ein Mix aus synthetischen Borsten und Naturborsten.It is also possible to arrange different bristles within a receiving opening, for example a mix of synthetic bristles and natural bristles.

In den Figuren 1 und 2 ist ein Pinsel gemäß einer ersten Ausführungsform gezeigt. Die wesentlichen Bestandteile dieses Pinsels sind ein Griff 10, eine Borstenträgerplatte 20 und ein Borstenpaket 30.In the Figures 1 and 2 a brush according to a first embodiment is shown. The essential components of this brush are a handle 10, a bristle carrier plate 20 and a bristle package 30th

Die Borstenträgerplatte 20 (siehe Figur 2) weist einen gitterartigen Körper 22 auf, in dem mehrere Aufnahmeöffnungen 24 ausgebildet sind, die durch Stege 26 voneinander getrennt sind. Die Aufnahmeöffnungen 24 dienen zur Aufnahme von Borstenbündeln 32, aus denen sich das Borstenpaket 30 zusammensetzt. Die Form der Aufnahmeöffnungen 24 ist im Wesentlichen bestimmt durch die gewünschten Eigenschaften des Pinsels und durch Festigkeitsanforderungen. Je größer der Flächenanteil der Aufnahmeöffnungen 24 an der Gesamtfläche des Körpers 22 ist, desto höher ist die Dichte des Borstenpakets 30. Allerdings sinkt dabei auch die Festigkeit der Borstenträgerplatte ab, da die Stege 26 entsprechend dünner ausgeführt werden müssen. Die Form der Aufnahmeöffnungen 24 hängt im Wesentlichen davon ab, wie die Borsten und die von den Aufnahmeöffnungen 24 gebildeten Borstenbündel 32 innerhalb des Borstenpakets 30 angeordnet sein sollen.The bristle carrier plate 20 (see FIG. 2 ) has a grid-like body 22 in which a plurality of receiving openings 24 are formed, which are separated by webs 26 from each other. The receiving openings 24 serve to receive bristle bundles 32, from which the bristle pack 30 is composed. The shape of the receiving openings 24 is essentially determined by the desired properties of the brush and by strength requirements. However, the larger the surface portion of the receiving openings 24 on the total surface of the body 22, the higher the density of the bristle package 30. However, the strength of the bristle carrier plate also decreases, since the webs 26 must be made correspondingly thinner. The shape of the receiving openings 24 depends essentially on how the bristles and the bristle bundles 32 formed by the receiving openings 24 are to be arranged within the bristle pack 30.

Die Stege 26 um die Aufnahmeöffnungen 24 herum können auf beiden Seiten mit Abschrägungen versehen sein, um zum einen das Einsetzen der Borstenbündel 32 in die Aufnahmeöffnungen 24 zu erleichtern und zum anderen die Verbindung der durch die Borstenträgerplatte 20 durchgesteckten Enden der Borsten mit der Borstenträgerplatte zu verbessern. Durch die Stege werden außerdem an der Basis des Borstenpakets Leerräume erzeugt, die als Vorratsraum für Farbe wirken. Durch geeignete Anordnung und Dimensionierung dieser Leerräume wird vorgegeben, wie viel Farbe dort zur Verfügung gestellt werden kann, wie viele Borsten mit der Farbe in Berührung stehen und wie schnell und gleichmäßig die Farbe von dort beim Streichen zu den Borstenspitzen geleitet wird.The webs 26 around the receiving openings 24 may be provided on both sides with bevels, on the one hand to facilitate the insertion of the bristle bundles 32 in the receiving openings 24 and the other the connection the end of the bristles with the bristle carrier plate pushed through the bristle carrier plate 20 to improve. The webs are also generated at the base of the bristle package empty spaces, which act as a storage space for color. By suitable arrangement and dimensioning of these voids, it is specified how much color can be made available there, how many bristles are in contact with the paint, and how quickly and uniformly the paint is guided from there to the bristle tips during brushing.

Der gitterartige Körper 22 ist an seiner Außenseite mit einem Bund 28 (siehe auch Figur 1) versehen, der dazu dient, den Griff 10 aufzunehmen. Auf der anderen Seite des gitterartigen Körpers 22 ist ein zweiter Bund 29 vorgesehen, der das Borstenpaket 30 umgibt und dazu dient, die Borsten zu stützen. Der Bund 29 ist hier so ausgeführt, dass seine Wände von der Borstenträgerplatte weg konvergieren. Auf diese Weise werden die Borsten besonders gut zusammengehalten und gestützt.The grid-like body 22 is on its outside with a collar 28 (see also FIG. 1 ), which serves to receive the handle 10. On the other side of the grid-like body 22, a second collar 29 is provided which surrounds the bristle pack 30 and serves to support the bristles. The collar 29 is here designed so that its walls converge away from the bristle carrier plate. In this way, the bristles are particularly well held together and supported.

Die Borstenbündel 32 werden mit den Enden, die in dem Pinsel verankert werden sollen, durch die Aufnahmeöffnungen 24 durchgesteckt. Anschließend werden die durch den gitterartigen Körper 22 durchgesteckten Enden miteinander verbunden. Bei der ersten Ausführungsform wurden zu diesem Zweck die Enden der Borsten miteinander verschweißt, so dass die in Figur 1 gezeigten, pilzförmigen Schweißköpfe 34 gebildet sind. Alternativ können die Enden der Borsten in eine gemeinsame, durchgehende filmartige Kunststoffmasse geschmolzen werden. Die filmartige Kunststoffmasse kann gleichmäßig dick sein oder über ihre Oberfläche unterschiedliche Dicken haben. Beispielsweise kann an den Stellen, an denen sich Borstenbündel befinden, eine Verdickung der filmartigen Kunststoffmasse geformt werden. Gleichzeitig können die Enden der Borstenbündel 32 mit der Borstenträgerplatte 20 verschweißt werden, genauer gesagt mit den die Aufnahmeöffnungen 24 umgebenden Stegen 26. Zu diesem Zweck ist die Borstenträgerplatte 20 vorzugsweise aus einem Kunststoff hergestellt, welches mit dem Material der Borsten verschweißt werden kann.The bristle bundles 32 are pushed through the receiving openings 24 with the ends that are to be anchored in the brush. Subsequently, the inserted through the grid-like body 22 ends are connected together. In the first embodiment, the ends of the bristles were welded together for this purpose, so that the in FIG. 1 shown, mushroom-shaped welding heads 34 are formed. Alternatively, the ends of the bristles may be melted into a common continuous film-like plastic mass. The film-like plastic mass may be uniformly thick or have different thicknesses over its surface. For example, a thickening of the film-like plastic compound may be formed at the locations where bristle bundles are located. At the same time, the ends of the bundles of bristles 32 can be welded to the bristle carrier plate 20, more precisely with the webs surrounding the receiving openings 24. For this purpose, the bristle carrier plate 20 is preferably made of a plastic which can be welded to the material of the bristles.

Der Griff 10 ist in den Bund 28 eingesetzt und dort mit diesem mittels einer Schicht aus Klebstoff 12 verbunden. Als Klebstoff kann beispielsweise ein Kunstharz verwendet werden. Der Bund 28 hat dabei den Vorteil, dass er zum einen den Griff 10 präzise aufnimmt, so dass eine mechanisch stabile Befestigung geschaffen wird. Zum anderen gewährleistet der Bund 28, dass kein Klebstoff 12 und auch kein Material der miteinander verschweißten Enden der Borstenbündel 32 nach außen austreten kann. Es ist also eine optisch sehr saubere Verbindung zwischen dem Griff 10 und der Borstenträgerplatte 20 gewährleistet.The handle 10 is inserted into the collar 28 and connected thereto by means of a layer of adhesive 12. As the adhesive, for example, a synthetic resin can be used. The collar 28 has the advantage that on the one hand the handle 10 receives precisely, so that created a mechanically stable attachment becomes. On the other hand, the collar 28 ensures that no adhesive 12 and also no material of the ends of the bundles of bristles 32 welded together can escape to the outside. So it is a visually very clean connection between the handle 10 and the bristle carrier plate 20 guaranteed.

Anstelle mittels des Klebstoffes 12 kann der Griff auch auf andere Weise mit der Borstenträgerplatte 20 verbunden werden, beispielsweise durch eine Rast- oder Clipsverbindung, durch Nägel, Schrauben oder durch ein Gewinde. Es ist auch möglich, den Griff 10 beispielsweise aus Kunststoff auszuführen und direkt in die Borstenträgerplatte 20 einzuspritzen, so dass er dort befestigt ist.Instead of by means of the adhesive 12, the handle can be connected in other ways with the bristle carrier plate 20, for example by a detent or clip connection, by nails, screws or by a thread. It is also possible to carry out the handle 10, for example made of plastic, and to inject it directly into the bristle carrier plate 20, so that it is fastened there.

In den Figuren 3 und 4 ist ein Pinsel gemäß einer zweiten Ausführungsform gezeigt. Für die von der ersten Ausführungsform bekannten Bauteile werden dieselben Bezugszeichen verwendet, und es wird insoweit auf die obigen Erläuterungen verwiesen.In the FIGS. 3 and 4 a brush according to a second embodiment is shown. For the components known from the first embodiment, the same reference numerals are used, and reference is made to the above explanations in this respect.

Allgemein ausgedrückt besteht der Unterschied zwischen der ersten und der zweiten Ausführungsform darin, dass bei der zweiten Ausführungsform nicht der Griff in die Borstenträgerplatte eingesetzt ist, sondern die Borstenträgerplatte 20 in den Griff 10. Zu diesem Zweck ist der Griff mit einer Aufnahme 14 versehen, die nach Art eines großen Sacklochs ausgeführt ist. In die Aufnahme 14 wird die mit den Borsten bestückte Borstenträgerplatte 20 eingesetzt (siehe den Fall P in Figur 4). Die Aufnahme 14 ist dabei so tief ausgeführt, dass der freie Rand der die Aufnahme 14 bildenden Schürze das Borstenpaket 30 ähnlich umgibt und stützt wie der Bund 29 bei der ersten Ausführungsform.Generally speaking, the difference between the first and the second embodiment is that in the second embodiment, not the handle is inserted into the bristle carrier plate, but the bristle carrier plate 20 in the handle 10. For this purpose, the handle is provided with a receptacle 14 which designed in the manner of a large blind hole. Into the receptacle 14, the bristle carrier plate 20 equipped with the bristles is inserted (see the case P in FIG FIG. 4 ). The receptacle 14 is designed so deep that the free edge of the receptacle 14 forming apron surrounds the bristle pack 30 similar and supports as the collar 29 in the first embodiment.

Die Borstenträgerplatte 20 ist bei der zweiten Ausführungsform ohne einen Bund gebildet. Es ist lediglich auf der Seite, auf der die Enden der Borsten mit der Borstenträgerplatte 20 verbunden werden, ein kleiner Kragen 21 vorgesehen, der verhindert, dass ein zum Befestigen der Borstenbündel 32 verwendeter Klebstoff 12 seitlich von der Borstenträgerplatte 20 herunterfließt. Der Kragen 21 sorgt weiterhin für eine höhere mechanische Stabilität der Borstenträgerplatte 20.The bristle carrier plate 20 is formed in the second embodiment without a collar. It is only on the side on which the ends of the bristles are connected to the bristle carrier plate 20, a small collar 21 is provided which prevents a used for fixing the bristle bundle 32 adhesive 12 flows laterally from the bristle carrier plate 20. The collar 21 furthermore ensures a higher mechanical stability of the bristle carrier plate 20.

Zur Befestigung der mit den Borsten bestückten Borstenträgerplatte 20 im Inneren der Aufnahme 14 kann entweder, wie in Figur 3 gezeigt, ein Klebstoff 12 verwendet werden, oder es kann eine beliebige andere Befestigungsart eingesetzt werden.For fixing the bristle carrier equipped with the bristle carrier plate 20 in the interior of the receptacle 14 can either, as in FIG. 3 shown, an adhesive 12 may be used, or it may be used any other type of attachment.

Ein weiterer Unterschied zur ersten Ausführungsform besteht darin, dass der die Borsten umgebende Bund mit parallelen Wänden ausgeführt ist. Dies ermöglicht, den Bund mit geringem Aufwand im Spritzgussverfahren zu fertigen.Another difference from the first embodiment is that the collar surrounding the bristles is designed with parallel walls. This makes it possible to produce the federal government with little effort by injection molding.

In den Figuren 5 bis 7 ist eine dritte Ausführungsform gezeigt. Für die von den vorhergehenden Ausführungsformen bekannten Bauteile werden dieselben Bezugszeichen verwendet, und es wird insoweit auf die obigen Erläuterungen verwiesen.In the FIGS. 5 to 7 a third embodiment is shown. For the components known from the preceding embodiments, the same reference numerals are used, and reference is made to the above explanations in this respect.

Der wesentliche Unterschied zwischen der ersten und der dritten Ausführungsform besteht darin, dass bei der dritten Ausführungsform der Flächenanteil der Aufnahmeöffnungen 24 für die Borstenbündel 32 kleiner ist als bei der ersten Ausführungsform. Dadurch ergibt sich eine geringere Dichte des Borstenpakets 30. Außerdem ist zu sehen, dass der Flächenanteil der Aufnahmeöffnungen 24 in einem äußeren Ringbereich des gitterartigen Körpers 22 größer ist als in der Mitte.The essential difference between the first and third embodiments is that in the third embodiment, the area ratio of the receiving openings 24 for the bristle bundles 32 is smaller than in the first embodiment. This results in a lower density of the bristle package 30. In addition, it can be seen that the surface portion of the receiving openings 24 in an outer annular region of the grid-like body 22 is greater than in the middle.

In den Figuren 8 und 9 ist ein Borstenpaket 30 mit Borstenträgerplatte 20 für einen Pinsel gemäß einer vierten Ausführungsform gezeigt. Für die von den vorhergehenden Ausführungsformen bekannten Bauteile werden dieselben Bezugszeichen verwendet, und es wird insoweit auf die obigen Erläuterungen verwiesen.In the FIGS. 8 and 9 a bristle package 30 is shown with bristle carrier plate 20 for a brush according to a fourth embodiment. For the components known from the preceding embodiments, the same reference numerals are used, and reference is made to the above explanations in this respect.

In Figur 10 sind verschiedene Varianten der Borstenträgerplatte 20 gezeigt, die sich durch unterschiedlich gestaltete Aufnahmeöffnungen 24 und unterschiedliche Stege zwischen den Aufnahmeöffnungen unterscheiden. Zusätzlich zu der sich daraus ergebenden, unterschiedlichen Dichte des Borstenpakets des entsprechenden Pinsels werden durch die Stege an der Basis des Borstenpakets Vorratsräume für Farbe erzeugt. Bei der Variante in Figur 10a wird ein annähernd ringförmig rechteckiger Vorratsraum gebildet, während in der Variante von Figur 10b ein mittiger Vorratsraum gebildet ist, der mit acht "Erkern" versehen ist. Bei der Variante von Figur 10c ist ähnlich wie in Figur 10a ein allgemein rechteckig umlaufender Vorratsraum gebildet, dessen Querschnitt sich zur Mitte hin aber vergrößert.In FIG. 10 different variants of the bristle carrier plate 20 are shown, which differ by differently shaped receiving openings 24 and different webs between the receiving openings. In addition to the resulting different density of the bristle pack of the respective brush, paint spaces are created by the lands at the base of the bristle pack. In the variant in FIG. 10a an approximately annular rectangular storage space is formed, while in the variant of FIG. 10b a central reservoir is formed, which is provided with eight "bay window". In the variant of FIG. 10c is similar to in FIG. 10a formed a generally rectangular circumferential storage space, the cross-section but increases towards the center.

Der wesentliche Unterschied zwischen der ersten und der vierten Ausführungsform besteht darin, dass die Borstenträgerplatte 20 bei der vierten Ausführungsform rechteckig ist. Es werden auch rechteckige Aufnahmeöffnungen für die Borstenbündel 32 verwendet, wie in Figur 9 anhand der Gestalt und der Anordnung der verschweißten Enden der Borstenbündel zu sehen ist.The essential difference between the first and fourth embodiments is that the bristle carrier plate 20 is rectangular in the fourth embodiment. There are also rectangular receiving openings for the Bristle bundle 32 used as in FIG. 9 can be seen by the shape and the arrangement of the welded ends of the bristle bundles.

In Figur 11 ist ein Pinsel gemäß einer fünften Ausführungsform gezeigt. Für die von den vorhergehenden Ausführungsformen bekannten Bauteile werden dieselben Bezugszeichen verwendet, und es wird insoweit auf die obigen Erläuterungen verwiesen.In FIG. 11 a brush according to a fifth embodiment is shown. For the components known from the preceding embodiments, the same reference numerals are used, and reference is made to the above explanations in this respect.

Der wesentliche Unterschied zur beispielsweise ersten Ausführungsform besteht darin, dass bei der fünften Ausführungsform der Griff 10 hohl ausgeführt und aus zwei Schalen 40, 42 zusammengesetzt ist. Einstückig mit dem Griff 10 ist der Bund 29 ausgeführt, der das Borstenpaket 30 stützt und zusammenhält. Zu diesem Zweck läuft der Bund nach vorne hin konisch zusammen. Die Borstenträgerplatte 20 ist im Griff mittels einer umlaufenden Nut 44 aufgenommen (siehe Figur 12), die in den beiden Schalen 40, 42 ausgebildet ist.The essential difference from, for example, the first embodiment is that in the fifth embodiment, the handle 10 is hollow and composed of two shells 40, 42. Integral with the handle 10, the collar 29 is executed, which supports the bristle pack 30 and holds together. For this purpose, the federal government converges conically towards the front. The bristle carrier plate 20 is received in the handle by means of a circumferential groove 44 (see FIG. 12 ) formed in the two shells 40, 42.

Die Borstenträgerplatte 20 kann einfach mechanisch in der Nut 44 gehalten werden. Alternativ kann die Borstenträgerplatte 20 eingeklebt oder eingeschweißt werden.The bristle carrier plate 20 can simply be held mechanically in the groove 44. Alternatively, the bristle carrier plate 20 can be glued or welded.

Der hohle Griff gemäß der fünften Ausführungsform führt zu einem Pinsel mit sehr geringem Gewicht. Außerdem lassen sich die beiden Schalen 40, 42 sehr einfach in einer Spritzgussform herstellen, da sich jede Schale leicht entformen lässt; die Formtrennebene läuft mittig durch den Griff. Außerdem kann bei dieser Ausgestaltung der Bund 29 problemlos konisch zulaufend ausgeführt werden,The hollow handle according to the fifth embodiment results in a brush with very low weight. In addition, the two shells 40, 42 can be very easily produced in an injection mold, since each shell can be easily removed from the mold; the mold parting plane runs through the middle of the handle. In addition, in this embodiment, the collar 29 can be easily tapered running,

In Figur 13 ist eine erste Variante zur fünften Ausführungsform gezeigt. Der Unterschied zu dem in Figur 11 gezeigten Pinsel besteht darin, dass der Griff im Inneren durch drei Rippen 46 verstärkt ist, so dass er auch dann, wenn eine geringe Wandstärke verwendet wird, nicht zusammengedrückt werden kann.In FIG. 13 a first variant of the fifth embodiment is shown. The difference to that in FIG. 11 shown brush is that the handle is reinforced inside by three ribs 46 so that it can not be compressed even if a small wall thickness is used.

In Figur 14 ist eine zweiten Variante zur fünften Ausführungsform gezeigt. Der Unterschied zu dem in Figur 11 gezeigten Pinsel besteht darin, dass im Bereich des Übergangs vom Bund 29 zum Griff 10 eine Abschlussplatte 48 angeordnet ist. Diese dient zum einen als Abstützung für die Borstenträgerplatte 20 und verhindert, dass die Borstenträgerplatte 20 durch einen übermäßig starken Druck auf das Borstenbündels 30 in den Griff 10 hineingedrückt werden kann. Die Abschlussplatte 48 dient zum anderen als Trennung zwischen dem Bereich des Borstenbündels 30 und dem Griff 10 und verhindert, dass Farbe in das Innere des hohlen Griffs 10 gelangen kann.In FIG. 14 a second variant of the fifth embodiment is shown. The difference to that in FIG. 11 shown brush is that in the region of the transition from the collar 29 to the handle 10, a cover plate 48 is arranged. This serves as a support for the bristle carrier plate 20 and prevents the bristle carrier plate 20 can be pressed by an excessively strong pressure on the bristle bundle 30 in the handle 10. The end plate 48 serves as a separation between the region of the Bristle bundle 30 and the handle 10 and prevents color can get into the interior of the hollow handle 10.

In Figur 15 ist eine dritte Variante zur fünften Ausführungsform gezeigt. Der Unterschied zu dem in Figur 11 gezeigten Pinsel besteht darin, dass die beiden Schalen 40, 42 als Mehrkomponententeil ausgeführt sind. Beim gezeigten Beispiel sind im Griffbereich auf die beiden Schalen 40, 42 zwei Abschnitte 50 aus einem Kunststoff aufgespritzt, der weicher ist als das Material der beiden Schalen 40, 42, beispielsweise aus thermoplastischem Elastomer. Ein solches weicheres Kunststoffmaterial verbessert das Griffgefühl und kann dabei je nach Anforderung geeignet angeordnet werden, beispielsweise als Abstützung für den Daumen und/oder den Zeigefinger des Benutzers.In FIG. 15 a third variant of the fifth embodiment is shown. The difference to that in FIG. 11 shown brush is that the two shells 40, 42 are designed as a multi-component part. In the example shown, in the grip area on the two shells 40, 42, two sections 50 of a plastic are injected, which is softer than the material of the two shells 40, 42, for example of thermoplastic elastomer. Such a softer plastic material improves the feel of the handle and can be suitably arranged as required, for example as a support for the user's thumb and / or forefinger.

Gemäß einer weiteren, nicht dargestellten Variante kann vorgesehen sein, dass der Bund 29 aus einem nachgiebigen Material an die beiden Schalen 40, 42 angespritzt wird, die den Griff 10 bilden. Auf diese Weise wird eine in gewissen Grenzen nachgiebige Abstützung für das Borstenpaket 30 erhalten. Es ist auch möglich, den Bund nur teilweise aus dem nachgiebigen Material zu spritzen, während andere Teile aus demselben, härteren Material wie der Griff 10 hergestellt werden.According to a further, not shown variant can be provided that the collar 29 is molded from a resilient material to the two shells 40, 42, which form the handle 10. In this way, a yielding within certain limits support for the bristle package 30 is obtained. It is also possible to inject the collar only partially from the compliant material, while other parts are made of the same, harder material as the handle 10.

Der Vollständigkeit halber wird darauf hingewiesen, dass die Merkmale der Figuren 13 bis 15 in beliebiger Weise miteinander kombiniert werden können.For the sake of completeness, it should be noted that the characteristics of the FIGS. 13 to 15 can be combined with each other in any way.

In Figur 16 sind die beiden Schalen 40, 42 im Schnitt gezeigt. Bei dem gezeigten Ausführungsbeispiel ist zu sehen, dass jede Schale 40, 42 auf einem Längsrand mit einem kleinen umlaufenden Schweißrand 52 versehen ist, dem ein ebener Rand der anderen Schale gegenüberliegt. Dies ermöglicht, die beiden Schalen durch Ultraschallschweißen miteinander zu verbinden. Besonders vorteilhaft ist dabei, dass die beiden Schalen 40, 42 identisch ausgeführt sind, so dass ein und dieselbe Spritzgussform zur Herstellung beider Schalen 40, 42 verwendet werden kann. Alternativ könnte der Schweißrand 52 auch nur an einer der beiden Schalen 40, 42 vorgesehen sein.In FIG. 16 the two shells 40, 42 are shown in section. In the embodiment shown, it can be seen that each shell 40, 42 is provided on a longitudinal edge with a small circumferential welding edge 52, which is opposite to a flat edge of the other shell. This makes it possible to connect the two shells by ultrasonic welding together. It is particularly advantageous that the two shells 40, 42 are made identical, so that one and the same injection mold for producing both shells 40, 42 can be used. Alternatively, the welding edge 52 could also be provided on only one of the two shells 40, 42.

Es ist auch möglich, die beiden Schalen 40, 42 auf andere Weise als durch Verschweißen miteinander zu verbinden. So können die beiden Schalen 40, 42 miteinander verklebt oder mechanisch verklipst werden, durch Spritzgießen miteinander verbunden werden (beispielsweise durch Umspritzen mit einer zweiten Materialkomponente).It is also possible to connect the two shells 40, 42 in a different way than by welding together. Thus, the two shells 40, 42 glued together or mechanically clipped, by injection molding together be joined (for example by encapsulation with a second material component).

Bei sämtlichen Ausführungsformen können für die Borsten unterschiedliche Materialien verwendet werden. Insbesondere können Borsten aus Kunststoff verwendet werden sowie aus Naturfasern, beispielsweise Schweinshaar, Rinderhaar, Dachs, etc. Bei Borsten aus Kunststoff können massive Borsten oder hohle Borsten verwendet werden. Die Querschnittsform der Borsten kann an die jeweiligen Anforderungen angepasst werden, beispielsweise rund sein, sternförmig, dreieckig, rechteckig, oder auch ein Gemisch verschiedener Querschnittsformen. Innerhalb einer Aufnahmeöffnung können auch unterschiedliche Borstenmaterialien kombiniert werden, beispielsweise Borsten aus Kunststoff mit Naturborsten. Die Spitzen der Borsten können vorbearbeitet sein, beispielsweise abgerundet oder angeschrägt.In all embodiments, different materials may be used for the bristles. In particular, plastic bristles may be used, as well as natural fibers such as pig hair, cattle hair, badger, etc. Bristles of plastic may use solid bristles or hollow bristles. The cross-sectional shape of the bristles can be adapted to the respective requirements, for example, be round, star-shaped, triangular, rectangular, or even a mixture of different cross-sectional shapes. Within a receiving opening and different bristle materials can be combined, for example, bristles made of plastic with natural bristles. The tips of the bristles may be preprocessed, for example, rounded or chamfered.

Abweichend von den gezeigten Ausführungsformen kann die Dicke des gitterförmigen Körpers variiert werden, so dass beispielsweise in mechanisch stärker belasteten Bereichen eine größere Dicke vorgesehen ist.Notwithstanding the embodiments shown, the thickness of the lattice-shaped body can be varied, so that, for example, a greater thickness is provided in mechanically more heavily loaded areas.

Ein besonderer Vorteil, der aus der Verwendung der Borstenträgerplatte 20 mit Aufnahmeöffnungen 24 resultiert, besteht darin, dass die Form des Borstenpakets 30 mit geringem Aufwand in der gewünschten Weise hergestellt werden kann, indem einfach die Borsten mehr oder weniger weit in die Aufnahmeöffnungen 24 eingeschoben werden. Es ist auch möglich, von vornherein Borsten mit unterschiedlichen Längen zu verwenden, so dass der Verschnitt minimiert ist, was zu geringeren Herstellungskosten führt.A particular advantage resulting from the use of the bristle carrier plate 20 with receiving openings 24, is that the shape of the bristle package 30 can be produced in the desired manner with little effort by simply more or less pushed the bristles into the receiving openings 24 , It is also possible to use from the outset bristles of different lengths, so that the waste is minimized, resulting in lower production costs.

Die Borstenträgerplatte kann mit Elementen wie Fingern, Lamellen, etc. versehen sein, die aus einem nachgiebigen Material bestehen können, beispielsweise aus thermoplastischem Elastomer. Diese Elemente können die Borsten innerhalb des Borstenpakets stützen. Mit solchen Elementen können auch spezielle Streicheffekte herbeigeführt werden, beispielsweise Struktureffekte. An der Borstenträgerplatte können zwischen den Borstenpaketen auch Elemente wie Schwämme, etc. vorgesehen sein, welche einen Farbvorrat bilden und die Farbabsorbtion bzw. -verteilung beeinflussen.The bristle carrier plate may be provided with elements such as fingers, fins, etc., which may be made of a compliant material, such as thermoplastic elastomer. These elements can support the bristles within the bristle package. With such elements also special coating effects can be brought about, for example structural effects. On the bristle carrier plate, elements such as sponges, etc. may be provided between the bristle packs, which form a color supply and influence the color absorption or distribution.
