Description

Die Erfindung geht von einer Bürste für Körperpflege gemäß dem Oberbegriff des Anspruchs 1 aus.The invention is based on a brush for personal care according to the preamble of claim 1.

Eine derartige Bürste, die vorzugsweise zum Reinigen von Hand- und Fußnägeln im Bereich des Nagelbetts vorgesehen ist, ist durch die DE 37 27 649 C1 bekannt. Diese Ausführung ist als Handwaschbürste ungeeignet, da sie nur eine tellerförmige Bürste vorsieht, mit der das Reinigen der ganzen Hand recht mühsam und zeitraubend ist.Such a brush, which is preferably provided for cleaning hand and toenails in the area of the nail bed, is known from DE 37 27 649 C1. This version is unsuitable as a hand washing brush, since it only provides a plate-shaped brush, with which cleaning the whole hand is very tedious and time-consuming.

Die Aufgabe der Erfindung besteht daher darin, eine Handwaschbürste mit netzunabhängigem Motorantrieb zu schaffen, die ein Reinigen der gesamten Handfläche einschließlich der Fingernägel ermöglicht. Die Bürste ist natürlich auch zum Reinigen von verschmutzten Füßen und Fußnägeln geeignet.The object of the invention is therefore to provide a hand wash brush with a mains-independent motor drive, which enables cleaning of the entire palm including the fingernails. The brush is of course also suitable for cleaning dirty feet and toenails.

Diese Aufgabe wird durch die im Anspruch 1 angegebenen Merkmale gelöst. Die Unteransprüche zeigen vorteilhafte Ausgestaltungen des Erfindungsgegenstandes auf.This object is achieved by the features specified in claim 1. The subclaims show advantageous configurations of the subject matter of the invention.

Die durch die Erfindung erzielten Vorteile bestehen insbesondere darin, daß eine Mehrzahl von vorzugsweise zylinderförmigen Bürsten vorgesehen sind, die parallel zueinander auf einem Kreisbogen in der Lagerplatine eines nierenförmigen Gehäuses dreh- und auswechselbar angeordnet sind. Die Gehäuseform ist der natürlichen Wölbung der Handinnenfläche angepaßt. Zwischen dem Antriebsmotor und den Bürsten ist ein Getriebe angeordnet, das so ausgebildet ist, daß die Bürsten alle gleiche Drehrichtung haben. Die Bürstenwalzen können gegen Zahnwalzen ausgewechselt werden, über die ein auf der Außenseite mit Borsten versehener endloser Zahnriemen in Umlauf versetzt wird.The advantages achieved by the invention are in particular in that a plurality of preferably cylindrical brushes are provided, which are arranged parallel to one another on a circular arc in the bearing plate of a kidney-shaped housing and can be exchanged. The shape of the case is adapted to the natural curvature of the palm of the hand. Between the drive motor and the brushes a gear is arranged, which is designed so that the brushes all have the same direction of rotation. The brush rollers can be exchanged for tooth rollers, by means of which an endless toothed belt provided with bristles on the outside is circulated.

Anhand eines Ausführungsbeispieles wird die Erfindung in Verbindung mit den Zeichnungen nachfolgend näher erläutert. Es zeigt:

Fig.1
eine Handwaschbürste gemäß der Erfindung in Perspektivdarstellung mit abgesetzten Bürstenwalzen.
Fig.2
die Handwaschbürste gemäß Fig.1 in einer anderen Perspektivdarstellung mit abgezogener Griffschale und einem Spritzschutz.
Using an exemplary embodiment, the invention is explained in more detail below in connection with the drawings. It shows:
Fig. 1
a hand washing brush according to the invention in perspective with offset brush rollers.
Fig. 2
the hand washing brush according to Figure 1 in a different perspective view with a detached grip and a splash guard.

Fig.1 zeigt in der Perspektive eine Handwaschbürste mit einem netzunabhängigen Motorantrieb. Das Gerät besteht im wesentlichen aus einem Gehäuse 1, das, wie später in Verbindung mit der Fig.2 noch näher erläutert wird, einen Gleichstrommotor 9 mit Untersetzungsgetriebe 10, ein Zahnriemengetriebe 4 und einen Satz wiederaufladbarer Batterien 11 umschließt. Das Gehäuse 1 hat ein nierenförmiges Profil. Die eine Schmalseite ist als Lagerplatine 2 ausgebildet, in der mehrere Wellen 8 in Buchsen mit Wellendichtung drehbar gelagert sind. In Anpassung an das gewählte Profil des Gehäuses 1 sind die Lager 7 auf einem von zwei Kreisbogen K1 bzw.K2 angeordnet. Während die drei mittleren Lager 7 auf dem Kreisbogen K1 mit Radius r1 liegen, sind die beiden äußeren Lager 7 auf dem Kreisbogen K2 mit einem etwas kürzeren Radius r2 angeordnet. Diese Anordnung gestattet bei gleichbleibendem Lagerabstand ein kompaktes Gerät mit nierenförmigem Gehäuseprofil. An die Form der Platine 2 ist das Profil der rückwärtigen Griffschale 20 angepaßt, mit der sie das Gehäuse 1 bildet. Im übrigen ist die Form des Gehäuses 1 an die natürliche Wölbung der Handinnenfläche angepaßt. In die Griffschale 20 ist ein Schieber 22 wasserdicht integriert. An seiner Unterseite ist ein Schaltmagnet befestigt, der Teil eines Magnetschalters ist. Rechts und links hat die Griffschale je zwei Führungsnuten 25 (nur jeweils eine ist in der Darstellung sichtbar), die zur Aufnahme eines Spritzschutzes 40 (Fig.2) vorgesehen sind.1 shows in perspective a hand washing brush with a mains-independent motor drive. The device essentially consists of a housing 1 which, as will be explained in more detail later in connection with FIG. 2, encloses a direct current motor 9 with a reduction gear 10, a toothed belt transmission 4 and a set of rechargeable batteries 11. The housing 1 has a kidney-shaped profile. One narrow side is designed as a bearing plate 2, in which a plurality of shafts 8 are rotatably mounted in bushings with a shaft seal. To match the selected profile of the housing 1, the bearings 7 are arranged on one of two circular arcs K1 and K2. While the three middle bearings 7 on the circular arc K1 with radius r1 lie, the two outer bearings 7 are arranged on the circular arc K2 with a slightly shorter radius r2. This arrangement allows a compact device with a kidney-shaped housing profile while keeping the bearing distance constant. The profile of the rear grip 20 with which it forms the housing 1 is adapted to the shape of the circuit board 2. Otherwise, the shape of the housing 1 is adapted to the natural curvature of the palm of the hand. A slide 22 is integrated in the handle shell 20 in a watertight manner. A switching magnet is attached to its underside, which is part of a magnetic switch. The handle shell has two guide grooves 25 on the right and left (only one each is visible in the illustration), which are provided for receiving a splash guard 40 (FIG. 2).

Zur lösbaren Aufnahme von Bürstenwalzen 30 haben die Wellen 8 ein axiales Sackloch. Die aus der Platine 2 vorstehenden Wellenstümpfe sind quergeschlitzt. Die Bürstenwalzen 30 haben einen in den Wellenkörper eingelassenen Zapfen 32, der diametral angeordnete Rastnasen 33 hat. Im aufgesteckten Zustand werden die Bürstenwalzen 30 über ihre Zapfen 32 im Sachloch der jeweiligen Welle 8 axial geführt, während die seitlichen Nasen 33 rastend in die Querschlitze der Wellen 8 eingreifen und einen Formschluß bewirken.The shafts 8 have an axial blind hole for releasably receiving brush rollers 30. The stub shafts protruding from the board 2 are cross-slotted. The brush rollers 30 have a pin 32 which is embedded in the shaft body and which has diametrically arranged detents 33. In the plugged-on state, the brush rollers 30 are guided axially via their pins 32 in the shaft hole of the respective shaft 8, while the side lugs 33 engage in the transverse slots of the shafts 8 and cause a positive connection.

Die Bürstenwalzen 30 sind gemäß Fig.1 am Umfang und stirnseitig mit einer Vielzahl Borstenbüschel 31 versehen. Der Teilungsabstand der Wellen 8 ist nur etwas größer als der Durchmesser der Walzenkörper 34. Die Borstenbüschel 31 von benachbarten Bürstenwalzen 30 sind daher auf Lücke angeordnet.The brush rollers 30 are provided with a plurality of bristle tufts 31 on the circumference and on the face side according to FIG. The pitch of the shafts 8 is only slightly larger than the diameter of the roller body 34. The bristle tufts 31 of adjacent brush rollers 30 are therefore arranged in a gap.

Fig.2 zeigt die Handwaschbürste gemäß Fig.1 in einer anderen Persprektivdarstellung bei abgenommener Griffschale 20, so daß der durch die Griffschale geschützte Teil des Gerätes sichtbar ist. An der Innenseite ist parrallel zur Lagerplatine 2 eine Getriebeplatine 3 angeordnet. In dieser sind die Wellen 8 mit ihrem rückwärtigen Ende drehbar gelagert. Auf jeder der Wellen 8 ist ein Zahnriemenrad 5 fest angeordnet. An die Getriebeplatine 3 ist der mit einem Untersetzugsgetriebe 10 eine Einheit bildende Gleichstrommotor 9 angeflanscht. Die Antriebswelle (in der Darstellung nicht sichtbar) ragt in den Raum zwischen den beiden Platinen 2 und 3 und trägt am Ende ein Zahnriemenrad 5. Über einen mit allen Zahnriemenrädern 5 formschlüssig in Eingriff stehenden Zahnriemen 6 werden die Wellen 8 und damit die Bürstenwalzen 30 durch den Motor 9 in gleicher Drehrichtung angetrieben.FIG. 2 shows the hand washing brush according to FIG. 1 in a different perspective view with the handle shell 20 removed, so that the part of the device protected by the handle shell is visible. On the inside is parallel to the bearing board 2 a transmission board 3 is arranged. In this, the shafts 8 are rotatably supported with their rear end. A toothed belt wheel 5 is fixedly arranged on each of the shafts 8. The DC motor 9, which forms a unit with a reduction gear 10, is flanged to the transmission board 3. The drive shaft (not visible in the illustration) protrudes into the space between the two boards 2 and 3 and carries a toothed belt wheel 5 at the end the motor 9 driven in the same direction of rotation.

Die Stromversorgung des Motors 9 erfolgt durch einen Satz wiederaufladbarer Batterien 11, die zur Bereitstellung der notwendigen Spannung in nicht dargestellter Weise in Reihe geschaltet sind. Im Stromkreislauf liegt ein Magnetkontakt 13, der bei aufgesteckter Griffschale 20 über den am Schieber 22 befestigten Schaltmagnet berührungslos betätigbar ist. Die Griffschale 20 hat eine Ladebuchse 23, die über elektrische Leitungen 12 an die Batterien 11 angeschlossen ist und einen Anschluß an eine externe Ladequelle erlaubt. Durch eine Schutzkappe 24 kann die Ladebuchse 23 gegen Spritzwasser geschützt werden. Die aufgesteckte Griffschale 20 wird durch Schrauben 21 gesichert. Eine in eine Ringnut der Lagerplatine 2 eingelassene Dichtung 14 sorgt für eine Abdichtung der Griffschale 20 gegen die Platine 2.The motor 9 is supplied with power by a set of rechargeable batteries 11, which are connected in series in a manner not shown to provide the necessary voltage. In the circuit there is a magnetic contact 13, which can be actuated in a contactless manner when the handle shell 20 is attached via the switching magnet attached to the slide 22. The grip shell 20 has a charging socket 23 which is connected to the batteries 11 via electrical lines 12 and allows connection to an external charging source. The charging socket 23 can be protected against splash water by a protective cap 24. The attached handle 20 is secured by screws 21. A seal 14 embedded in an annular groove in the bearing plate 2 ensures that the grip shell 20 is sealed off from the plate 2.

Zum Schutz des Benutzers gegen Spritzwasser der rotierenden Bürstenwalzen 30 ist ein Spritzschutz 40 vorgesehen, der die momentan nicht benutzte Seite der Handwaschbürste abdeckt. Zu diesem Zweck ist der Spritzschutz 40 umsteckbar. Entsprechend den Führungsnuten 25 an der Griffschale 20 hat der Spritzschutz 40 zwei Führungsbacken 41, die im Abstand der lichten Breite der Griffschale 20 angeordnet und entsprechend der Außenkontur der Griffschale 20 im Bereich zwischen den paarweisen Führungsnuten 25 geformt sind. Die Längskanten der Führungsbacken 41 sind als leistenförmige Rastelemente 42 ausgebildet. Im aufgesteckten Zustand greifen die Rastelemente 42 formschlüssig in die Führungsnuten 25 in der Griffschale 20 ein und gewährleisten einen stabilen Halt des Spritzschutzes.To protect the user against splashing water from the rotating brush rollers 30, a splash guard 40 is provided, which covers the side of the hand washing brush that is not currently being used. For this purpose, the splash guard 40 can be changed over. Corresponding to the guide grooves 25 on the grip shell 20, the splash guard 40 has two guide jaws 41 which are arranged at a distance from the clear width of the grip shell 20 and corresponding to the Outer contour of the grip shell 20 are formed in the area between the paired guide grooves 25. The longitudinal edges of the guide jaws 41 are designed as strip-shaped locking elements 42. When plugged in, the latching elements 42 engage in a form-fitting manner in the guide grooves 25 in the grip shell 20 and ensure a stable hold of the splash guard.

Anstelle der Bürstenwalzen 30 können Zahnwalzen treten, die von einem auf der Außenseite mit Borsten versehenen Zahnriemen umspannt sind. Im Bereich der konkaven Wölbung der Zahnwalzen ist der Zahnriemen frei gespannt. Dadurch kann er sich den Unebenheiten der zu reinigenden Hand anpassen.Instead of the brush rollers 30, toothed rollers can be used which are spanned by a toothed belt provided with bristles on the outside. The toothed belt is freely tensioned in the area of the concave curvature of the toothed rollers. This enables him to adapt to the unevenness of the hand to be cleaned.

Um eine im Einzelfall verbesserte Reinigungswirkung zu erzielen, kann es wünschenswert sein, die Umlaufrichtung der Bürstenwalzen 30 bzw. des borstenbesetzten Zahnriemens zu ändern. Dieses läßt sich in einfacher Weise durch ein Umpolen des Gleichstrommotors 9 z.B. über einen zweiten als, Umschalter ausgebildeten Magnetschalter erreichen.In order to achieve an improved cleaning effect in individual cases, it may be desirable to change the direction of rotation of the brush rollers 30 or the bristle-covered toothed belt. This can be easily done by reversing the polarity of the DC motor 9 e.g. via a second magnetic switch designed as a changeover switch.
