DEUTSCHESGERMAN

Das Hauptpatent betrifft eine Scheibenschneideinrichtung, bestehend aus einem Messer mit Handgriff und aus zwei wahlweise am Handgriff anbringbaren, der Bemessung der Scheibendicke dienenden Leitanschlägen, von denen der jeweils handgriffseitig am Messer angebrachte Leitanschlag sich seitlich vor der Schneide der Messerklinge entlang der letzteren erstreckt und quer zur Klingenebene verstellbar ist.The main patent relates to a slicing device consisting of a knife with a handle and from two guide stops, which can be optionally attached to the handle and used to measure the pane thickness, of which the guide stop attached to the knife on the handle side is laterally in front of the The cutting edge of the knife blade extends along the latter and is adjustable transversely to the plane of the blade.

Hierbei ist der Leitanschlag so angeordnet, daß er mit einem handgriffseitig angeordneten geschlitzten Endlappen an einer Außenfläche des Handgriffes anliegt und eine den Schlitz durchdringende Schraube in Längsrichtung des Schlitzes verstellbar gehalten wird. Beim Lösen der Halteschraube zwecks Einstellung der Leitanschläge verlieren diese jedoch ihre Führung am Handgriff und können im losen Zustand leicht die Messerschneide beschädigen. Die richtige Gebrauchslage der Leitanschläge ist von der Genauigkeit ihrer Anschlagfläche am Handgriff abhängig. Bei Benutzung des Messers ohne Leitanschläge ist deren am Handgriff befindliche Führungsfläche Beschädigungen ausgesetzt, welche bei Gebrauch des Messers mit Leitanschlägen deren Führung beeinträchtigen können.Here, the guide stop is arranged so that it is slotted with a handle side arranged End tabs on an outer surface of the handle and a screw penetrating the slot is held adjustable in the longitudinal direction of the slot. When loosening the retaining screw for adjustment However, the guide stops lose their guidance on the handle and can in the loose state easily damage the knife edge. The correct position of use of the guide stops depends on the accuracy depending on their stop surface on the handle. When using the knife without guide stops, their The guide surface on the handle is exposed to damage that occurs when the knife is used with guide stops can impair their guidance.

Erfindungsgemäß wird die Scheibenschneideinrichtung nach dem Hauptpatent wesentlich vereinfacht und verbessert, indem bei einer Scheibenschneideinrichtung der vorerwähnten Art für den handgriffseitigen federnden Verbindungsteil der Leitanschläge ein im Kopf des Messergriffes angebrachter, der Dicke des Verbindungsteiles entsprechender Einsteck- und Führungsschlitz und am Ende desselben eine parallel zum Einsteckschlitz verlaufende Einsteckbohrung mit quer dazu verlaufendem Haltmittel für eine am freien Ende des Verbindungsteiles vorgesehene Hülse angeordnet sind. Weitere Einzelheiten der Erfindung sind in der Beschreibung im Zusammenhang mit der Zeichnung näher erläutert.According to the invention, the slicing device according to the main patent is considerably simplified and improved by a slicing device of the aforementioned type for the handle-side resilient connecting part of the guide stops a mounted in the head of the knife handle, the Thickness of the connecting part of the corresponding insertion and guide slot and at the end of the same one parallel Insertion hole running to the insertion slot with holding means running transversely to it for an am free end of the connecting part provided sleeve are arranged. Further details of the invention are explained in more detail in the description in connection with the drawing.

Dicke verbreitert ist. Dieser Kopf 13 weist eine durchgehende Einsteckbohrung 14 und einen von dieser bis an die klingenseitige Außenfläche des Handgriffes 12 reichenden Einsteckschlitz 15 auf, welche beide quer zur Klingenebene verlaufen. Ferner ist im Kopf 13 seitwärts der Klinge 10 eine von der Oberseite des Handgriffes bis zur Bohrung 14 reichende Gewindebohrung 16 angeordnet, in welche eine mit gerändeltem Kopf 17 versehene Klemmschraube 18 eingeschraubt ist.Thickness is widened. This head 13 has a through insertion hole 14 and one of these up to the blade-side outer surface of the handle 12 reaching insertion slot 15, which both run across the plane of the blade. Further, in the head 13 sideways of the blade 10 is one from the top of the handle up to the bore 14 reaching threaded bore 16 arranged in which a with knurled head 17 provided clamping screw 18 is screwed.

Der aus den Fig. 1,2 und 4 ersichtliche LeitanschlagThe guide stop shown in FIGS. 1, 2 and 4

20 besteht aus Stahlblech und besitzt einen quer zur Klingenebene liegenden, federnden Tragsteg21, welcher vom Handgriff 12 ausgehend freistehend seitlich zur Klingenebene in der Ruhelage größtenteils knapp vor bzw. unter dem geradlinigen Teil der Messerschneide 11 an diesem entlang sich erstreckt und gegen das frei stehende Ende an Breite abnimmt. Das entgegengesetzte, griffseitige Ende des Verbindungstragsteges20 is made of sheet steel and has a resilient support web21 lying transversely to the plane of the blade, which starting from the handle 12 free-standing laterally to the blade plane in the rest position largely just ahead or under the rectilinear part of the knife edge 11 extends along this and against the free standing end decreases in width. The opposite, handle-side end of the connecting support web

21 ist beispielsweise zu einer zylindrischen Hülse gerollt, mittels welcher der mit dem federnden Verbindungsteil 21 durch den schrägen Schlitz 15 nach oben in den Griff 12 eintretende Leitanschlag 20 in der Bohrung 14 des Griffes 12 in deren Achsrichtung verschiebbar geführt ist. Die Weite des Schlitzes 15 entspricht der Dicke des Verbindungsteiles 21, so daß sich die Hülse 22 in der Bohrung 14 nicht drehen kann. Dagegen ist der Verbindungsteil 21 zwischen dem Griff 12 und der an der klingenseitigen Verbindungsteilkante 23 nach unten abgewinkelten Anschlagwand 24 elastisch biegsam, damit der frei stehende Teil des21 is rolled, for example, into a cylindrical sleeve, by means of which the with the resilient connecting part 21 through the inclined slot 15 entering the handle 12 upward guide stop 20 in the Bore 14 of the handle 12 is guided displaceably in the axial direction. The width of the slot 15 corresponds the thickness of the connecting part 21, so that the sleeve 22 cannot rotate in the bore 14. In contrast, the connecting part 21 is between the handle 12 and that on the connecting part edge on the blade side 23 downwardly angled stop wall 24 elastically flexible so that the free-standing part of the

Claims

Guide stop 20 can spring back if necessary until the slightly concave or approximately straight edge piece 26 of the same from the lower, rounded end 25 of the stop wall 24 towards the handle reaches the same level as the straight part of the knife edge 11 and is therefore practical for cutting through clippings enables the use of the entire length of the cutting edge. From Fig. 3 it can be seen that the axial direction of the bore 14 and the corresponding direction of the slot 15 are slightly inclined relative to the normal plane laid by the straight part of the knife edge 11 at right angles to the plane of the blade or is approximately as perpendicular to the plane of the blade flank facing the stop rail that the blade-side Yerbverbindungsteilkante 23 is slightly removed from this blade flank when the stop rail receding upwards. In the rest position of the guide stop 20, the stop wall 24 runs approximately parallel to the blade flank and is slightly bent back at the lower end 25 towards the side of the connecting part 21 (FIG. 4). The slot 15 is located on the rail-side flank of the blade of the handle 12 above the knife edge 11, and the edge 27 of the support web 21 runs slightly obliquely in the direction of the handle 12, so that there is a stop shown in FIG. 1 for the rail 20 results on the blade 10, which prevents contact of the knife edge with the rail (Fig. 2). The sleeve 22 protrudes over the edge 27 of the blade 21 and thereby enables a sufficiently large transverse displacement of the stop rail 20, which can be locked in the desired position by means of the clamping screw 18, the shaft end of the screw 18 entering the bore 14 being the elastically deformable Sleeve 22 presses in the bore in a slightly oval shape and presses against the wall of the bore, whereby an excellent clamping of the guide stop 20 is achieved. With the clamping screw 18 loosened, the stop rail can not only be moved as required but, if desired, pulled completely out of the guide hole 14 in order to be able to use the knife 10 either without a guide stop 20 or to equip it with the stop rail 30 shown in FIGS. In Fig. 5 the guide stop 30 is designed at its handle-side end in the same way as the rail 20 described and can be adjusted transversely in the bore 14 or in the slot 15 of the handle head 13 by means of the cylindrical sleeve 31 and the adjoining connecting part 32 transverse to the blade plane and guided in a lockable manner by means of the clamping screw 18. In this application, however, the knife is preferably used with the cutting edge pointing upwards. The connecting part 32 emerging from the slot 15 slightly below the cutting edge according to FIG. 5 extends laterally to the blade plane for the most part just in front of or above the straight-line part of the cutting edge 11 to the connecting part 32 upwardly angled flat stop wall 34, the plane of which is approximately parallel to the blade flank facing away from it. At the end of the guide stop opposite to the handle there is a parking foot 35 which protrudes near the knife tip beyond the knife back 19 and is formed by an angled part 36 of the blade 32 and a part of the stop wall 34 running along it. The flat standing surface 36 of the parking foot 35 closes with the longitudinal direction of the knife an angle of, for. B. about 30 ° a. The back of the knife 19 rests on a support leg 37 which is fastened transversely and which is supported by a cuff, e.g. B. made of rubber or other material which increases the friction between the knife back and cuff, can be enclosed. Instead of the bore 14 in the head 13 of the handle 12, a non-circular hole, for. B. a triangular or square hole, or a slot part angled to the slot 15 can be provided, which, however, consistently causes higher manufacturing costs than the drilling. The end of the guide stops on the handle side would then be designed in a correspondingly suitable manner. As in the case of the guide stop 20 and for the same purpose, the sheet between the handle and the stop wall 34 can also be elastically flexible in the case of the guide stop 30. Patent claims:
