Die bekannte Vorrichtung hat sich zwar hervorragend bewahrt, sie ist jedoch zu groß und zu schwer, um in einer Tasche transportiert werden zu können.The known device has proven to be excellent, but it is too large and too heavy to be transported in a pocket.
Aufgabe der Erfindung ist es daher, eine derartige Messerscharfvorrichtung im Taschenformat bereitzustellen.The object of the invention is therefore to provide such a knife sharpener in pocket format.
Dies wird erfindungsgemaß dadurch erreicht, dass die Wetzstabe in einem Gehäuse angeordnet und gelagert sind, dessen Vorderwand und Ruckwand zur Bildung einer Messereinfuhroffnung mit parallel zueinander verlaufenden Schlitzen versehen sind, die an einem Ende offen und am anderen Ende geschlossen sind.This is achieved according to the invention in that the sharpening rods are arranged and mounted in a housing, the front wall and rear wall of which, to form a knife insertion opening, are provided with mutually parallel slots which are open at one end and closed at the other end.
Das Gehäuse ist vorzugsweise flach und im Wesentlichen qua- derformig, d.h., die Vorder- und die Ruckwand verlaufen planparallel. Es ist vorzugsweise etwa handtellergroß, so dass die erfindungsgemaße Vorrichtung bequem in einer Tasche getragen werden kann. D.h., das Gehäuse weist vorzugsweise eine Lange und Breite von 5 bis 10 cm und eine Dicke von 1 bis 3 cm auf. Es besteht vorzugsweise aus Kunststoff oder einem ähnlichen leichten Material.The housing is preferably flat and essentially rectangular, ie the front and rear walls run plane-parallel. It is preferably about the size of a palm, so that the device according to the invention can be carried comfortably in a pocket. That is, the housing preferably has one Long and wide from 5 to 10 cm and a thickness of 1 to 3 cm. It is preferably made of plastic or a similar light material.
Um die Wetzstabe und die Federn in dem Gehäuse montieren zu können, ist es vorzugsweise zwischen der Vorder- und der Ruckwand geteilt. Dabei kann die Teilungsfuge planparallel zur Vorderwand und Ruckwand verlaufen. Das Gehäuse kann jedoch auch in anderer Weise ausgebildet sein, beispielsweise schachteltor ig .In order to be able to mount the sharpening rod and the springs in the housing, it is preferably divided between the front and the rear wall. The dividing joint can run plane-parallel to the front wall and rear wall. However, the housing can also be designed in a different way, for example box gate.
Die Wetzstabe sind vorzugsweise sowohl an der Vorder- wie an der Ruckwand des Gehäuses gelagert. Vorzugsweise sind die Wetzstabe an ihrer vorderen und ihrer hinteren Seite mit Drehzapfen versehen, die in eine Ausnehmung in der Vorderwand bzw. der Ruckwand eingreifen. Stattdessen können die Drehzapfen auch an der Vorder- und der Ruckwand vorgesehen sein, wobei dann die Ausnehmungen, in die die Drehzapfen eingreifen, an der Vorderseite und der Ruckseite der Wetzstabe vorgesehen sind.The sharpening rods are preferably mounted on both the front and rear walls of the housing. The sharpening rods are preferably provided on their front and rear sides with pivot pins which engage in a recess in the front wall and the rear wall, respectively. Instead, the pivot pins can also be provided on the front and rear wall, in which case the recesses into which the pivot pins engage are provided on the front side and the rear side of the sharpening rod.
Um eine sichere Fuhrung der Wetzstabe zu erreichen, sind die bogenförmigen Fuhrungen vorzugsweise durch Ausnehmungen gebildet, die sowohl in der Vorder- wie der Ruckwand vorgesehen sind. In die parallel zueinander verlaufenden bogenförmigen Ausnehmungen in der Vorder- und der Ruckwand greifen Fuh- rungszapfen ein, die sowohl an der Vorderseite wie der Ruckseite der Wetzstabe vorgesehen sind. Die Federn, die die Wetzstabe aufeinander zu belasten und entgegen deren Kraft die Wetzstabe durch einen Druck des Messers auseinandergespreizt werden, sind vorzugsweise durch Stahldrahte gebildet, die mit einem Ende vorzugsweise an der Ruckwand befestigt sind und mit ihrem anderen Ende auf der von der Messereinfuhroffnung abgewandten Seite an dem der bogenförmigen Fuhrung zugewandten Seite der Wetzstabe angreifen. Zur Befestigung der Federdrahte sind vorzugsweise an der Ruckwand des Gehäuses Nuten angebracht, in die das eine Ende des Federdrahtes gelegt wird und die durch einen Vorsprung in der Vorderwand verschlossen werden, wenn das vordere Gehauseteil und das hintere Gehauseteil zusammengefugt werden.In order to achieve safe guidance of the sharpening rod, the arcuate guides are preferably formed by recesses which are provided in both the front and the rear wall. Guide pins, which are provided both on the front side and on the rear side of the sharpening rod, engage in the arcuate recesses in the front and rear walls which run parallel to one another. The springs, which load the sharpening rod against one another and against whose force the sharpening rod is spread apart by a pressure of the knife, are preferably formed by steel wires, which are preferably attached at one end to the rear wall and with their other end on the side facing away from the knife insertion opening Grip side on the side of the sharpening rod facing the curved guide. For fastening the spring wires, grooves are preferably provided on the rear wall of the housing, into which one end of the spring wire is placed and which are closed by a projection in the front wall when the front housing part and the rear housing part are joined together.
Um zu verhindern, dass, abgesehen vom Bereich der Wetzstabe, aus dem die Schleifspane über die Schlitze in der Vorderwand und der Ruckwand entfernt werden können, Schleifspane in den übrigen Innenraum des Gehäuses gelangen, ist der Bereich der Wetzstabe von dem übrigen Innenraum des Gehäuses vorzugsweise durch eine Zwischenwand getrennt, die an der Vorderwand oder der Ruckwand oder zum Teil an der Vorderwand und zum Teil an der Ruckwand vorgesehen ist. Die Zwischenwand kann, insbesondere wenn das Gehäuse aus Kunststoff hergestellt ist, emstu- ckig mit dem vorderen Teil des Gehäuses mit der Vorderwand bzw. mit dem hinteren Teil des Gehäuses mit der Ruckwand ausgebildet sein.In order to prevent, apart from the area of the sharpening rod from which the grinding chips can be removed via the slots in the front wall and the rear wall, grinding chips come into the rest of the interior of the housing, the area of the sharpening rod is preferably from the rest of the interior of the housing separated by an intermediate wall which is provided on the front wall or the rear wall or partly on the front wall and partly on the rear wall. The intermediate wall, in particular if the housing is made of plastic, can be integrally formed with the front part of the housing with the front wall or with the rear part of the housing with the rear wall.
Um das Vorderteil des Gehäuses mit dem hinteren Teil des Gehäuses zu verbinden, können hulsenformige Ansätze an der Vorder- oder der Ruckwand vorgesehen sein, in die Bolzen steckbar sind, die an der entsprechenden Gegenwand befestigt sind. Insbesondere bei einem Kunststoffgehause können auch diese hulsenformigen Ansätze und Steckbolzen einstuckig mit der Vorder- oder Ruckwand ausgebildet sein.In order to connect the front part of the housing to the rear part of the housing, sleeve-shaped projections can be provided on the front or rear wall, into which bolts can be inserted, which are fastened to the corresponding counter wall. In the case of a plastic housing in particular, these sleeve-shaped lugs and plug pins can also be formed in one piece with the front or rear wall.
Um die Vorrichtung zum Messerschleifen auf einer Unterlage aufstellen zu können, kann an der Unterseite, also an der von der Messereinfuhrung abgewandten Seite des Gehäuses ein Standfuß angelenkt sein, der in der Messerscharfposition der Vorrichtung ausgeklappt und in der Trageposition der Vorrichtung eingeklappt wird. Der Standfuß ist vorzugsweise platten- formig ausgebildet und auf die Vorderwand schiebbar. Dazu kann der Standfuß zwei Zapfen aufweisen, die in einer Langs- nut an der einen bzw. anderen der zueinander parallel verlaufenden Schmalseiten des Gehäuses eingreifen, zwischen denen die Schlitze der Einfuhroffnungen liegen. Die Zapfen an dem Standfuß dienen also einerseits zur Fuhrung des Standfußes beim Verschieben in die Trageposition, wie zum Verschwenken des aus der Trageposition herausgeschobenen Standfußes in die ausgeklappte MesserscharfStellung.In order to be able to set up the device for knife grinding on a base, a base can be articulated on the underside, i.e. on the side of the housing facing away from the knife insertion, which is folded out in the knife sharp position of the device and folded in the carrying position of the device. The base is preferably plate-shaped and can be pushed onto the front wall. To the base can have two pins which engage in a longitudinal groove on one or the other of the narrow sides of the housing which run parallel to one another and between which the slots of the insertion openings lie. The pins on the pedestal thus serve on the one hand to guide the pedestal when moving into the carrying position, and to pivot the pedestal pushed out of the carrying position into the unfolded knife-sharp position.
Zur Fixierung des Gehäuses in der ausgeklappten Stellung in einem Winkel von vorzugsweise etwa 60 bis 80 ° zwischen dem Gehäuse und dem Standfuß ist am Gehäuse und/oder am Standfuß ein Anschlag vorgesehen. Dieser Anschlag wird vorzugsweise durch Seitenwande an dem Standfuß gebildet, auf denen sich die Seitenwande des hinteren Teils des Gehäuses in der ausgeklappten Standfußstellung, also MesserscharfStellung, abstutzen .To fix the housing in the unfolded position at an angle of preferably approximately 60 to 80 ° between the housing and the base, a stop is provided on the housing and / or on the base. This stop is preferably formed by side walls on the pedestal, on which the side walls of the rear part of the housing are supported in the unfolded pedestal position, that is to say the knife-sharp position.
Die Seitenwande des vorderen Teils des Gehäuses sind gegenüber den Seitenwanden des hinteren Teils des Gehäuses so nach innen versetzt, dass sie an der Innenseite der Seitenwande des Standfußes verlaufen.The side walls of the front part of the housing are offset inwards from the side walls of the rear part of the housing such that they run on the inside of the side walls of the base.
Die Kanten des flachen, quaderformigen Gehäuses sind zur Erhöhung des Tragekomforts vorzugsweise abgerundet ausgebildet. Zu diesem Zweck ist auch der Standfuß an seiner dem Zapfen abgewandten Seite vorzugsweise mit einer gewölbten Stirnwand versehen, die in der eingeklappten und auf das Gehäuse geschobenen Stellung des Standfußes die von der Messereinfuhroffnung abgewandte Stirnwand des Gehäuses fluchtend übergreift. Desgleichen ist vorzugsweise die Vorderwand des Gehäuses an ihrer der Messereinfuhroffnung zugewandten Seite mit einem Vorsprung versehen, der den platten ormigen Standfuß in der eingeklappten und auf das Gehäuse geschobenen Stellung an der Kante, an der er die Zapfen aufweist, fluch- tend übergreift. Zudem ist vorzugsweise die Stirnseite des Gehäuses, an der die Messereinfuhroffnung vorgesehen ist, gewölbt ausgebildet. Damit weist die erfindungsgemaße Messerscharfvorrichtung in der Trageposition, abgesehen von der Messereinfuhroffnung, glatte Außenseiten sowie gewölbt ausgebildete Stirnseiten auf und damit keine Kanten, die den Tragekomfort beeinträchtigen konnten.The edges of the flat, cuboid-shaped housing are preferably rounded in order to increase the wearing comfort. For this purpose, the base on its side facing away from the pin is preferably provided with a curved end wall which, in the folded position and pushed onto the housing, overlaps the end wall of the housing facing away from the knife insertion opening. Likewise, the front wall of the housing is preferably provided on its side facing the knife insertion opening with a projection which curses the plate-shaped base in the folded position and pushed onto the housing at the edge at which it has the pins. tends to spread. In addition, the end face of the housing on which the knife insertion opening is provided is preferably curved. As a result, the knife sharpener according to the invention, in addition to the knife insertion opening, has smooth outer sides and arched end faces in the carrying position and therefore no edges which could impair the wearing comfort.
Nachstehend ist eine Ausfuhrungsform der erfindungsgemaßen Messerscharfvorrichtung anhand der beigefugten Zeichnung naher erläutert. Darin zeigen:An embodiment of the knife sharpener according to the invention is explained in more detail below with the aid of the attached drawing. In it show:
