Description

Stand der TechnikState of the art

Die Erfindung geht aus von einer Vorrichtung zum Reinigen einer Tafel aus Stahlblech nach dem Oberbegriff des Anspruchs 1.The invention is based on a device for cleaning a sheet of sheet steel according to the preamble of claim 1.

Derartige Tafeln sind an ihrer Oberfläche meist weiß beschichtet. Zum Schreiben oder Zeichnen auf der Tafel werden Stifte verwendet. Die Beschriftungen oder Zeichnungen können durch Wischen mit einem trockenen Tuch über die Tafeloberfläche entfernt werden. Derartige Tücher haben jedoch den Nachteil eines geringen Komforts für den Benutzer.Such panels are usually white coated on their surface. Pens are used to write or draw on the board. The labels or drawings can be removed by wiping with a dry cloth over the surface of the board. However, such towels have the disadvantage of low comfort for the user.

Aus der DE 298 07 569 U1 ist eine Vorrichtung zum Löschen von auf einer Tafel aufgebrachten Information bekannt. Die Vorrichtung besteht aus einem Kunststoffgehäuse, in welches ein Reinigungstuch eingespannt ist. Bei einer starken Verschmutzung kann das Tuch entfernt und durch ein neues Tuch ersetzt werden. Die Vorrichtung hat den Nachteil, dass die Herstellung des Kunststoffgehäuses relativ aufwendig ist und die Vorrichtung ein relativ hohes Gewicht aufweist. Dies liegt zum einen an dem Gewicht des Kunststoffgehäuses und zum anderen an dem in dem Gehäuse vorgesehenen Permanentmagneten, der dafür sorgt, dass die Vorrichtung auch bei Nichtgebrauch an der Tafel haften bleibt. Darüber hinaus ist das Auswechseln des Reinigungstuchs mit einem großen Aufwand verbunden, da das Gehäuses geöffnet und nach dem Entfernen des verschmutzten Tuchs ein sauberes Tuch eingespannt werden muß. Zum Öffnen des Gehäuses sind die beiden ineinander einrastenden Gehäuseteile mit Hilfe eines Schraubenziehers oder eines anderen Werkzeugs auseinander zu drücken. Das Reinigungstuch ist mit zwei seiner Enden durch hierfür vorgesehene Schlitze zu ziehen. Damit sind mehrere Arbeitsschritte und Werkzeuge zum Austausch des Reinigungstuchs notwendig.From the DE 298 07 569 U1 An apparatus for erasing information applied on a panel is known. The device consists of a plastic housing, in which a cleaning cloth is clamped. If soiled, the cloth can be removed and replaced with a new cloth. The device has the disadvantage that the production of the plastic housing is relatively expensive and the device has a relatively high weight. This is due, on the one hand, to the weight of the plastic housing and, on the other hand, to the permanent magnet provided in the housing, which ensures that the device stick to the board even when not in use. In addition, the replacement of the cleaning cloth is associated with a great effort, since the housing must be opened and after removing the soiled cloth a clean cloth must be clamped. To open the housing, push the two interlocking housing parts apart with the help of a screwdriver or other tool. The cleaning cloth should be pulled with two of its ends through slots provided for this purpose. This requires several work steps and tools to replace the cleaning cloth.

Eine weitere Vorrichtung zum Reinigen einer Tafel ist aus US 2002/0104180 bekannt.Another device for cleaning a panel is off US 2002/0104180 known.

Die Erfindung und ihre VorteileThe invention and its advantages

Demgegenüber hat die erfindungsgemäße Vorrichtung mit den Merkmalen des Anspruchs 1 den Vorteil, dass sie ein wesentlich geringeres Gewicht aufweist und einfacher sowie kostengünstiger herzustellen ist. Der Griffteil der Vorrichtung besteht aus einem Block eines geschäumten starren Materials. Dieser Block ist wesentlich leichter als die Kunststoffteile der aus dem Stand der Technik bekannten Vorrichtungen. Da das Material starr ist und sich nur durch die Einwirkung einer größeren Kraft verformen lässt, kann der zum Reinigen teilweise notwendige Druck von der Hand des Benutzers auf den Reinigungsstreifen der Vorrichtung übertragen werden. Zur Herstellung des Griffteils wird der Block aus einem größeren Teil beispielsweise unter Einsatz einer Wasserstrahltechnik herausgeschnitten. Damit ist die Herstellung des Griffteils wesentlich einfacher und kostengünstiger durchzuführen, als bei den zumeist im Spritzgussverfahren hergestellten Griffteile des Standes der Technik. Das geschäumte starre Material, welches für die Herstellung des Griffteils benötigt wird, kann ebenfalls kostengünstig produziert werden und ist daher preiswert zu beziehen.In contrast, the device according to the invention with the features of claim 1 has the advantage that it has a much lower weight and is easier and cheaper to produce. The handle portion of the device consists of a block of foamed rigid material. This block is considerably lighter than the plastic parts of the devices known from the prior art. Since the material is rigid and can only be deformed by the action of a larger force, the pressure which is sometimes necessary for cleaning can be transferred from the user's hand to the cleaning strip of the device. To produce the handle part of the block is cut out of a larger part, for example, using a water jet technique. Thus, the production of the handle part is much easier and cheaper to perform, as in the case of the most commonly produced by injection molding handle parts of the prior art. The foamed rigid material, which is needed for the production of the handle part, can also be produced inexpensively and is therefore inexpensive to obtain.

An dem Griffteil ist ein Klettstreifen zum lösbaren Befestigen des Reinigungsstreifens vorgesehen. Ist der Reinigungsstreifen daher stark verschmutzt, so wird er durch den Benutzer im Randbereich angehoben und von dem Klettstreifen abgezogen. Anschließend wird ein neuer Reinigungsstreifen durch einfaches Auflegen auf den Klettstreifen und leichtes Anpressen an dem Griffteil befestigt. Der Austausch des Reinigungsstreifens ist somit einfach und schnell durchzuführen. Zusätzliche Werkzeuge, wie sie beispielsweise zum Öffnen des Kunststoffgehäuses der aus dem Stand der Technik der DE 298 07 569 U1 bekannt sind, sind bei der erfindungsgemäßen Vorrichtung nicht notwendig. Der an dem Klettstreifen verhakte Reinigungsstreifen haftet trotz des leichten Lösens so gut an dem Griffteil, dass eine zuverlässige Reinigung der Tafel garantiert ist.On the handle part, a Velcro strip for releasably securing the cleaning strip is provided. If the cleaning strip is therefore heavily soiled, it is lifted by the user in the edge region and removed from the Velcro strip. Subsequently, a new cleaning strip is attached by simply placing on the Velcro strips and light pressing on the handle. The replacement of the cleaning strip is thus easy and quick to perform. Additional tools, such as those for opening the plastic housing of the prior art of DE 298 07 569 U1 are known, are not necessary in the device according to the invention. Despite being easily loosened, the cleaning strip hooked to the Velcro strip adheres so well to the grip part that reliable cleaning of the board is guaranteed.

Die Vorrichtung kann nicht nur zum Reinigen einer Tafel aus Stahlblech, sondern auch zum Reinigen sonstiger glatter Oberflächen verwendet werden. Zum Beseitigen von Beschriftungen oder Verunreinigungen von der Tafel oder von sonstigen Oberflächen ist es häufig ausreichend, mit dem trockenen Reinigungsstreifen über die Oberfläche zu wischen. Lösen sich die Verunreinigungen dabei nicht, so können zusätzlich flüssige Reinigungsmittel verwendet werden. Diese werden entweder auf die zu reinigende Oberfläche oder auf den Reinigungsstreifen der Vorrichtung aufgetragen. Zum schnelleren Trocknen kann der feuchte Reinigungsstreifen durch einen Handgriff von der Vorrichtung gelöst und separat ausgelegt werden.The device can be used not only for cleaning a sheet of sheet steel but also for cleaning other smooth surfaces. To remove labels or contaminants from the panel or other surfaces, it is often sufficient to wipe over the surface with the dry cleaning strip. If the impurities do not dissolve, additional liquid cleaning agents can be used. These are applied either to the surface to be cleaned or to the cleaning strip of the device. For faster drying of the wet cleaning strip can be solved by a handle of the device and designed separately.

Nach einer vorteilhaften Ausgestaltung der Erfindung ist der Griffteil der Vorrichtung an der der Tafel oder einer anderen Oberfläche zugewandten Seite eben ausgebildet und weist an der der Hand eines Benutzers zugewandten Seite eine runde Form auf. Die ebene und flach ausgebildete Seite, an der der Klettstreifen und der Reinigungsstreifen befestigt sind, sorgt damit dafür, dass der Reinigungsstreifen vollständig auf der zu reinigenden Oberfläche aufliegen kann. Damit wird eine optimale Reinigungswirkung erzielt. Die dem Reinigungsstreifen abgewandte Seite ist dagegen rund oder gewölbt ausgebildet und passt sich damit optimal der Hand des Benutzers an. Die Vorrichtung liegt damit leicht und angenehm in der Hand.According to an advantageous embodiment of the invention, the handle part of the device is flat on the side facing the panel or another surface and has a round shape on the side facing the hand of a user. The flat and flat side, to which the Velcro strip and the cleaning strip are attached, thus ensures that the cleaning strip completely on the zu can rest on the cleaning surface. For an optimal cleaning effect is achieved. The side facing away from the cleaning strip, however, is round or curved and optimally adapts to the hand of the user. The device is thus easy and comfortable in the hand.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind in der dem Klett- und Reinigungsstreifen zugewandten Seite des Griffteils eine oder mehrere Vertiefungen für einen oder mehrere Permanentmagneten vorgesehen. Da der Griffteil, der Klettstreifen und der Reinigungsstreifen ein sehr geringes Gewicht aufweisen, wird lediglich eine kleine magnetische Kraft benötigt, um die Vorrichtung an einer Tafel aus Stahlblech haften zu lassen. Im Unterschied zu den aus dem Stand der Technik bekannten Vorrichtungen können daher wesentlich kleinere Permanentmagneten verwendet werden. Dies sorgt wiederum insgesamt für ein geringes Gewicht der erfindungsgemäßen Vorrichtung. In einer bevorzugten Ausführungsform haben die Permanentmagneten eine zylindrische Form, vergleichbar mit einer kleinen Münze oder einem kleinen Knopf. Der Durchmesser kann dabei weniger als 11,0 mm betragen. Da die Permanentmagneten im Vergleich zu der Fläche, mit welcher die Vorrichtung an der Tafel anliegt, eine wesentlich kleinere Ausdehnung haben, kann es von Vorteil sein, nicht nur einen, sondern zwei kleine zylindrische Permanentmagneten räumlich getrennt voneinander vorzusehen. Die Vertiefungen in dem Griffteil sind an die Form der Permanentmagneten angepasst, so dass die Permanentmagneten umschlossen werden und deren Oberfläche mit der Oberfläche des Griffteils abschließt. Durch den Klettstreifen werden die Permanentmagneten abgedeckt und in den Vertiefungen gehalten.According to a further advantageous embodiment of the invention, one or more recesses for one or more permanent magnets are provided in the side facing the velcro and cleaning strip side of the handle part. Since the handle portion, the Velcro strip and the cleaning strip have a very low weight, only a small magnetic force is needed to adhere the device to a sheet of sheet steel. In contrast to the devices known from the prior art, therefore, much smaller permanent magnets can be used. This in turn ensures a total of a low weight of the device according to the invention. In a preferred embodiment, the permanent magnets have a cylindrical shape comparable to a small coin or a small button. The diameter can be less than 11.0 mm. Since the permanent magnets have a substantially smaller expansion compared to the surface with which the device rests on the panel, it may be advantageous to provide not just one, but two small cylindrical permanent magnets spaced apart from each other. The depressions in the grip part are adapted to the shape of the permanent magnets, so that the permanent magnets are enclosed and their surface is flush with the surface of the grip part. The Velcro strips cover the permanent magnets and hold them in the recesses.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung ist der Klettstreifen an seiner dem Griffteil zugewandten Oberfläche mit einem Klebstoff beschichtet. Zum Befestigen des Klettstreifens muss daher lediglich eine Schutzfolie abgezogen, der Klettstreifen auf den Griffteil aufgelegt und ausgerichtet sowie angedrückt werden. Das Aufbringen des selbstklebenden Klettstreifens auf den Griffteil erfolgt damit in einem Arbeitsschritt und ohne die Verwendung zusätzlicher Werkzeuge.According to a further advantageous embodiment of the invention, the Velcro strip is coated on its surface facing the handle part with an adhesive. To attach the Velcro strip therefore only a protective film must be removed, the Velcro strips on the handle be put on and aligned and pressed. The application of the self-adhesive Velcro strip on the handle is done so in one step and without the use of additional tools.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung besteht der Reinigungsstreifen aus Filz. Dieser hat den Vorteil, dass die durch trockenes Wischen entfernte Farbe gebunden wird. Sie verbleibt damit weder auf der Tafel noch kann sie die Kleidung oder die Hände des Benutzers verschmutzen. Darüber hinaus können je nach Anwendungsfall auch Reinigungsstreifen aus Mikrofaser, Samt, Velours, Papier oder Zellstoff verwendet werden. Dank des Klettstreifens können die Reinigungsstreifen schnell und einfach ausgetauscht und damit an die jeweilige Anwendung angepasst werden. Der Klettstreifen hat den Vorteil, dass an den kleinen Häkchen alle Arten von Textilien und Papierreinigungstüchern haften.According to a further advantageous embodiment of the invention, the cleaning strip made of felt. This has the advantage that the color removed by dry wiping is bound. It will not remain on the board or contaminate the user's clothing or hands. In addition, depending on the application, cleaning strips made of microfiber, velvet, velor, paper or pulp can be used. Thanks to the Velcro strip, the cleaning strips can be quickly and easily replaced and adapted to the respective application. The Velcro strip has the advantage that adhere to the small hook all sorts of textiles and paper cleaning tissues.

Nach einer weiteren vorteilhaften Ausgestaltung der Erfindung sind der Reinigungsstreifen und/ oder der Griffteil und/ oder der Klettstreifen in der Waschmaschine waschbar. Damit können die Vorrichtung komplett oder nur einzelne Teile der Vorrichtung in der Waschmaschine gereinigt werden. Besonders geeignet ist hierzu eine Wassertemperatur von 30° C.According to a further advantageous embodiment of the invention, the cleaning strip and / or the handle part and / or the Velcro strips are washable in the washing machine. Thus, the device can be cleaned completely or only individual parts of the device in the washing machine. Particularly suitable for this purpose is a water temperature of 30 ° C.
