Definitions
- the invention relates to a hand cutting knife with a circular knife disc according to the preamble of the main claim for the rolling removal of certain cut shapes or for cutting continuous webs, such as wallpaper or the like.
- the knife protection cover is designed to be pivotable, as a result of which, after pivoting in the safety position, this protective cover covers the part of the knife disc which is not covered by the trough-shaped, knife-side end of the knife holder.
- the knife disc is thus between the protective cover and the trough-shaped end of the knife holder, remains freely accessible on one side and can therefore lead to injuries, quite apart from the fact that you can injure yourself when you swivel the protective cover on the knife disc itself.
- the invention is therefore based on the object to improve a hand cutting knife of the type mentioned in such a way that with simple and risk-free interchangeability of the knife disc, it is arranged so that it is covered absolutely securely in the knife holster and should be free from danger for the cutting process.
- the knife disc is to a certain extent embedded in a two-part trough, one part being formed by the trough-shaped end of the knife holder and, on the other hand, by the likewise trough-shaped and pivotable protective cover, which is provided with an adjustment handle, with which the pivoting of the protective cover is free of danger can be done.
- the knife disc, the protective cover and the shaft are assigned to the knife holder in such a way that they can be detached and plugged in, which means that these parts can be detached from one another transversely to the knife disc and can be put together again in the opposite direction, which also precludes any risk during these operations.
- the pivotable, trough-shaped protective cover is arranged on the same side with respect to the knife disc as the trough-shaped end of the knife holder, but this is not mandatory, since the trough-shaped knife protective cover could also be arranged on the other side of the knife disc, which means that the knife disc is located between the two trough-shaped parts.
- the above-mentioned arrangement of the two trough-shaped parts on one side of the knife disk is therefore preferred because advantageous developments to be described are thereby easier to implement, which will be explained in more detail below.
- the pivotable protective cover is namely advantageously mounted on a hub arranged concentrically to the shaft in the trough-shaped end of the knife holder, and the hub and the pivotable protective cover are provided with end stops through which the pivotable protective cover can be snapped exactly in the open and closed positions.
- the shaft is designed in the form of a plug pin with a larger diameter head and the head-free end of the plug pin is fixed with an attachable locking disk with respect to the trough-shaped end of the protective cover of the holder.
- the pivotable protective cover 1 is also trough-shaped and has a circumferential web 2 which is guided along a circumferential web 3 of the trough-shaped end 4 of the knife holder 5.
- This trough-shaped design and assignment of the end 4 of the knife holder 5 and of the protective cover 1 is particularly clear from FIG. 2.
- the protective cover 1, the knife disc 6 and the shaft 7 are detachably and pluggably assigned to the knife holder 5, specifically, as can also be seen in FIG. 2, by means of the shaft 7 designed as a plug pin 11. These elements all together form the knife head 5 '.
- FIGS. 1 As can be seen from FIGS.
- the protective cover 1 is provided with an adjusting handle 8 which is sufficiently far with respect to the overall arrangement and above the cutter disk 6, as can be seen in particular from FIG. 2. Since the cutting edge of the cutter disk 6 is completely shielded from the circumferential webs 2, 3, the actuation of the adjusting handle 8 can be carried out without any risk.
- the representation in Fig. 1 corresponds to the position of the protective cover 1 ready for cutting, i.e. that is, with its circumferential web 2 parallel to the circumferential web 3 of the trough-shaped end 4 of the knife holder 5.
- the cut-side boundary edges of the two trough-shaped parts of the knife holder 5 are arranged as shown in dashed lines in order to ensure an unobstructed cut of the knife.
- the pivotable protective cover 1 is mounted on a hub 9 arranged in the trough-shaped end 4 of the knife holder 5 concentrically with the shaft 7, and the hub 9 and the pivotable protective cover 1 are provided with end stops 10 '.
- a circularly curved elongated hole 10 "in the protective cover 1 leads to sufficient elasticity of the web 10" which remains between the elongated hole 10 "and the hub attachment opening 9 ', on which the end stops 10' are seated, which, depending on the position and when the protective cover 1 is assigned to the trough of the knife holder 5 cooperate with a corresponding cam-shaped stop 10 on the hub 9.
- These stops 10, 10 ' are arranged in such a way that the locking of the cam-like stop 10 once the closed position (FIG. 7) and once the open position (FIG. 1) corresponds.
- the shaft 7 is in the form of a plug pin 11 with a larger diameter head 12, the head-free end 13 of the plug pin 11 being fixed with an attachable locking disk 14 with respect to the trough-shaped end 4 of the knife holder 5, as shown in FIG. 2 becomes clear. From this it can also be seen that only the locking disk 14, which of course has a corresponding sliding gap, only has to be pressed off by the plug pin 11 in order to be able to take the whole structure apart. The release of the locking disk 14 takes place completely safely from the knife disk 6 on the other side of the knife holder 5, so that after loosening the locking disk 14 only the plug pin 11 and the knife disk 6 are to be removed from the trough, replaced and replaced.
- the shaft 7 and the plug pin 11 are rotatably arranged in the knife holder 5, for which the hub 9, as shown in FIG. 3, is provided with a straight surface 18 within the plug-through hole and the plug 11 itself is also provided with a corresponding surface 17. Since the shaft 7 or the plug pin 11 is thus fixed, the cutter disk 6 rotates on the shaft 7, which elements are therefore provided with a bush 15 rotatably fitted on the shaft 7, the bush 15 being provided with a flange collar 15 'and this is arranged adjacent to the head 12 of the plug pin 11, as is also clear from FIG. 2.
- the knife holder 5 or the knife head 5 ' on which, as can be seen from FIGS. 1, 2 and 7, a small glass cutting knife 19, as shown, can also be arranged with a connection adapter 16, with which the entire cutter head 5 'can be interchangeably assigned to a suitable cutter handle 20.

Abstract
Description
Die Erfindung betrifft ein Handschneidmesser mit kreisförmiger Messerscheibe gemäß Oberbegriff des Hauptanspruches zum rollenden Ausscheiden bestimmter Zuschnittsformen oder zum Abschneiden von fortlaufenden Bahnen, wie bspw. Tapeten od. dgl.The invention relates to a hand cutting knife with a circular knife disc according to the preamble of the main claim for the rolling removal of certain cut shapes or for cutting continuous webs, such as wallpaper or the like.
Derartige Handschneidmesser mit kreisförmiger Messerscheibe sind allgemein, aber hier druckschriftlich nicht belegbar, bakannt und in Benutzung. Beim Handschneidmesser der eingangs genannten Art ist die Messerschutzabdeckung verschwenkbar ausgebildet, wodurch diese Schutzabdeckung nach Verschwenken in Sicherheitsstellung den Teil der Messerscheibe abdeckt, der vom muldenförmigen, messerseitigen Ende des Messerhalters nicht abgedeckt wird. Die Messerscheibe befindet sich also hierbei zwischen Schutzabdeckung und muldenförmigen Ende des Messerhalters, bleibt dadurch nach einer Seite frei zugänglich und kann deshalb zu Verletzungen führen, ganz abgesehen davon, daß man sich allein schon beim Verschwenken der Schutzabdeckung an der Messerscheibe selbst verletzen kann. Außerdem ist bei diesem vorbekannten Handschneidmesser das Auswechseln der Messerscheibe im Bedarfsfall geradezu gefährlich, da die Schutzabdeckung gleichzeitig als Sperrelement für den Zusammenhalt der ganzen Messeranordnung sorgt und beim abschließenden Aufstekken der Schutzabdeckung nach ausgewechselter Messerscheibe das Aufschieben bzw. Aufdrücken der Schutzabdeckung direkt auf die Messerschneide zu erfolgen muß.Such hand cutting knives with a circular knife disk are general, but cannot be documented here in printed form, known and in use. In the case of the hand cutting knife of the type mentioned at the outset, the knife protection cover is designed to be pivotable, as a result of which, after pivoting in the safety position, this protective cover covers the part of the knife disc which is not covered by the trough-shaped, knife-side end of the knife holder. The knife disc is thus between the protective cover and the trough-shaped end of the knife holder, remains freely accessible on one side and can therefore lead to injuries, quite apart from the fact that you can injure yourself when you swivel the protective cover on the knife disc itself. In addition, with this known hand-held knife, replacing the knife disc is absolutely dangerous if necessary, since the protective cover also acts as a locking element to keep the entire knife arrangement together and when the protective cover is plugged in after the knife disc has been replaced, the protective cover is pushed on or pressed directly onto the knife edge got to.
Der Erfindung liegt demgemäß die Aufgabe zugrunde, ein Handschneidmesser der eingangs genannter Art dahingehend zu verbessern, daß bei einfacher und gefährdungsfreier Auswechselbarkeit der Messerscheibe diese absolut sicher im Messerhalfter abgedeckt angeordnet und gefährdungsfrei für den Schnittvorgang freistellbar sein soll.The invention is therefore based on the object to improve a hand cutting knife of the type mentioned in such a way that with simple and risk-free interchangeability of the knife disc, it is arranged so that it is covered absolutely securely in the knife holster and should be free from danger for the cutting process.
Diese Aufgabe ist mit einem Handschneidmesser der eingangs genannten Art nach der Erfindung durch die im Kennzeichen des Hauptanspruches angeführten Merkmale gelöst. Vorteilhafte Weiterbildungen ergeben sich nach den Unteransprüchen. Die Merkmale der Ansprüche 4 und 6 sind nach der DE-OS 26 23 268 bekannt.This object is achieved with a hand cutting knife of the type mentioned according to the invention by the features stated in the characterizing part of the main claim. Advantageous further developments result from the subclaims. The features of claims 4 and 6 are known from DE-OS 26 23 268.
Durch diese erfindungsgemäße Ausbildung befindet sich die Messerscheibe gewissermaße eingebettet in einer zweiteiligen Mulde, wobei das eine Teil vom muldenförmigen Ende des Messerhalters gebildet ist und andererseits von der ebenfalls muldenförmigen und verschwenkbaren Schutzabdeckung, die mit einer Verstellhandhabe versehen ist, mit der das Verschwenken der Schutzabdeckung gefährdungsfrei erfolgen kann. Außerdem sind die Messerscheibe, die Schutzabdeckung und die Welle gemeinsam lös-und steckbar dem Messerhalter zugeordnet, was bedeutet, daß diese Teile quer zur Messerscheibe voneinander lösbar und in entgegengesetzter Richtung wieder zusammensteckbar sind, wodurch auch jegliche Gefährdung bei diesen Vorgängen ausgeschlossen ist.Due to this design according to the invention, the knife disc is to a certain extent embedded in a two-part trough, one part being formed by the trough-shaped end of the knife holder and, on the other hand, by the likewise trough-shaped and pivotable protective cover, which is provided with an adjustment handle, with which the pivoting of the protective cover is free of danger can be done. In addition, the knife disc, the protective cover and the shaft are assigned to the knife holder in such a way that they can be detached and plugged in, which means that these parts can be detached from one another transversely to the knife disc and can be put together again in the opposite direction, which also precludes any risk during these operations.
Vorzugsweise ist die schwenkbare, muldenförmige Schutzabdeckung in bezug auf die Messerscheibe auf der gleichen Seite angeordnet wie das muldenförmige Ende des Messerhalters, was aber nicht zwingend ist, da die muldenförmige Messerschutzabdeckung auch auf der anderen Seite der Messerscheibe angeordnet sein könnte, was bedeutet, daß sich die Messerscheibe zwischen den beiden muldenförmigen Teilen befindet. Bevorzugt wird die vorerwähnte Anordnung der beiden muldenförmigen Teile auf einer Seite der Messerscheibe deshald, weil dadurch noch zu beschreibende vorteilhafte Weiterbildungen einfacher zu verwirklichen sind, was noch näher erläutert wird.Preferably, the pivotable, trough-shaped protective cover is arranged on the same side with respect to the knife disc as the trough-shaped end of the knife holder, but this is not mandatory, since the trough-shaped knife protective cover could also be arranged on the other side of the knife disc, which means that the knife disc is located between the two trough-shaped parts. The above-mentioned arrangement of the two trough-shaped parts on one side of the knife disk is therefore preferred because advantageous developments to be described are thereby easier to implement, which will be explained in more detail below.
Die schwenkbare Schutzabdeckung wird nämlich vorteilhaft an einer im muldenförmigen Ende des Messerhalters konzentrisch zur Welle angeordneten Nabe gelagert und die Nabe und die schwenkbare Schutzabdeckung werden mit Endanschlägen versehen, durch die die schwenkbare Schutzabdeckung genau in Öffnungs- und Schließstellung eingerastet werden kann.The pivotable protective cover is namely advantageously mounted on a hub arranged concentrically to the shaft in the trough-shaped end of the knife holder, and the hub and the pivotable protective cover are provided with end stops through which the pivotable protective cover can be snapped exactly in the open and closed positions.
In Rücksicht auf die lös- und steckbare Zuordnung der Teile ist die Welle in Form eines Steckzapfens mit durchmessergrößerem Kopf ausgebildet und das kopffreie Ende des Steckzapfens mit einer aufsteckbaren Sperrscheibe in bezug auf das muldenförmige Ende der Schutzabdeckung des Halters fixiert. Nach Abdrücken der Sperr. scheibe, was bei geschlossener Stellung der Schutzabdeckung erfolgt, kann problemlos der Stekzapfen herausgezogen und damit die Messerscheibe ohne weiteres ausgewechselt bzw. erneuert werden. Das diese Vorgänge quer zur Messerscheibe und nicht gegen deren Schnittkante erfolgen und dabei die Schutzabdeckung in ihrer Sicherheitsstellung verbleiben kann, ist legliche Gefährdung ausgeschlossen.In view of the detachable and pluggable assignment of the parts, the shaft is designed in the form of a plug pin with a larger diameter head and the head-free end of the plug pin is fixed with an attachable locking disk with respect to the trough-shaped end of the protective cover of the holder. After pressing the lock. disc, which takes place when the protective cover is in the closed position, the plug can be pulled out without any problems and the knife disc can thus be easily replaced or replaced. The fact that these processes take place transversely to the knife disc and not against its cutting edge and the protective cover can remain in its safety position is a legal hazard.
Das erfindungsgemäße Handschneidmesser wird nachfolgen anhand der zeichnerischen Darstellung eines Ausführungsbeispieles näher erläutert.The hand cutting knife according to the invention is explained in more detail below with reference to the drawing of an exemplary embodiment.

Wie aus den Fig. 1 bis 4 erkennbar, ist die schwenkbare Schutzabdeckung 1 ebenfalls muldenförmig ausgebildet und weist einen Umfangssteg 2 auf, der längs eines Umfangssteges 3 des muldenförmigen Endes 4 des Messerhalters 5 geführt ist. Diese muldenförmige Ausbildung und Zuordnung vom Ende 4 des Messerhalters 5 und von der Schutzabdeckung 1 wird insbesondere aus Fig. 2 deutlich. Die Schutzabdeckung 1, die Messerscheibe 6 und die Welle 7 sind lös- und steckbar dem Messerhalter 5 zugeordnet und zwar, wie ebenfalls aus Fig. 2 erkennbar, mittels der als Steckzapfen 11 ausgebildeten Welle 7. Diese Elemente bilden alle zusammen den Messerkopf 5'. Wie aus Fig. 1 und 4 erkennbar, ist die Schutzabdeckung 1 mit einer Verstellhandhabe 8 versehen, die sich in bezug auf die Gesamtanordnung ausreichend weit und oberhalb der Messerscheibe 6 befindet, wie dies insbesondere aus Fig. 2 erkennbar ist. Da die Schneidkante der Messerscheibe 6 von den Umfangsstegen 2, 3 völlig abgeschirmt ist, kann die Betätigung der Verstellhandhabe 8 völlig gefährdungsfrei erfolgen. Die Darstellung in Fig. 1 entspricht übrigens der schneidbereiten Stellung der Schutzabdeckung 1, d. h., diese befindet sich mit ihrem Umfangssteg 2 parallel zum Umfangssteg 3 des muldenförmigen Endes 4 des Messerhalters 5. Die schnittseitigen Begrenzungskanten der beiden muldenförmigen Teile des Messerhalters 5 sind, wie gestrichelt dargestellt angeordnet, um eine unbehinderte Schnittführung des Messers zu gewährleisten.As can be seen from FIGS. 1 to 4, the pivotable
In Rücksicht auf die zur Messerscheibe 6 einseitige Zuordnung der beiden muldenförmigen Teile ist die schwenkbare Schutzabdeckung 1 an einer im muldenförmigen Ende 4 des Messerhalters 5 konzentrisch zur Welle 7 angeordneten Nabe 9 gelagert und die Nabe 9 und die schwenkbare Schutzabdekkung 1 mit Endanschlägen 10' versehen. Ein kreisförmig gebogenes Langloch 10" in der Schutzabdeckung 1 führt zu einer ausreichenden Elastizität des zwischen Langloch 10" und Nabenaufstecköffnung 9' stehenbleibenden Steges 10"', an dem die Endanschläge 10' sitzen, die je nach Stellung und bei Zuordnung der Schutzabdeckung 1 zur Mulde des Messerhalters 5 mit einem entsprechenden, nockenförmigen Anschlag 10 an der Nabe 9 zusammenwirken. Diese Anschläge 10, 10' sind so angeordnet, daß die Verrastung des nockenartigen Anschlages 10 einmal der Schließstellung (Fig. 7) und einmal der Öffnungsstellung (Fig. 1) entspricht.In view of the one-sided assignment of the two trough-shaped parts to the knife disk 6, the pivotable
Wie erwähnt, ist die Welle 7 in Form eines Steckzapfens 11 mit durchmessergrößerem Kopf 12 ausgebildet, wobei das kopffreie Ende 13 des Steckzapfens 11 mit einer aufsteckbaren Sperrscheibe 14 in bezug auf das muldenförmige Ende 4 des Messerhalters 5 fixiert ist, wie dies aus Fig. 2 deutlich wird. Daraus wird auch ersichtlich, daß man lediglich die Sperrscheibe 14, die natürlich einen entsprechenden Aufschiebespalt hat, lediglich vom Steckzapfen 11 abzudrücken hat, um das ganze Gebilde auseinandernehmen zu können. Das Lösen der Sperrscheibe 14 erfolgt dabei völlig ungefährdet von der Messerscheibe 6 auf der anderen Seite des Messerhalters 5, so daß nach Lösen der Sperrscheibe 14 lediglich der Steckzapfen 11 und die Messerscheibe 6 aus der Mulde herauszunehmen, auszuwechseln und wieder einzubringen sind. Die Welle 7 bzw. der Steckzapfen 11 sind verdrehfest im Messerhalter 5 angeordnet, wofür die Nabe 9, wie in Fig. 3 verdeutlicht, innerhalb der Steckzapfendurchgriffsbohrung mit einer geraden Fläche 18 und der Steckzapfen 11 selbst ebenfalls mit einer entsprechenden Fläche 17 versehen sind. Da die Welle 7 bzw. der Steckzapfen 11 somit feststeht, dreht sich die Messerscheibe 6 auf der Welle 7, welche Elemente deshalb mit einer auf der Welle 7 drehbar aufgesteckten Büchse 15 versehen sind, wobei die Büchse 15 mit einem Flanschbund 15' versehen und dieser am Kopf 12 des Steckzapfens 11 anliegend angeordnet ist, wie dies ebenfalls aus Fig. 2 deutlich wird. Diese Weiterbildung trägt insofern auch zur Sicherheit des Ganzen bei, als sich dabei und bei entsprechender Schneiddruckbelastung die relativ dünne Messerscheibe 6 nicht in die Welle 7 eindrücken und diese verschleißen kann, was im Laufe der Zeit zu einer nicht mehr exakten Führung der Messerscheibe 6 führen würde und diese somit verkanten und ggf. sogar über die Umfangsstege 2, 3 hervorstehen könnte. Abgesehen von geringfügigen Drehverschiebungen zwischen der Messerscheibe 6 und der Büchse 15, die nicht fest miteinander verbunden sein müssen, dreht sich also lediglich die Büchse in bezug auf die fixierte Welle 7, was natürlich außerdem zu einer Verschleißminderung führt, denn außer der Messerscheibe 6 werden alle Teile des Handschneidmessers aus zähelastischem Kunststoff gebildet.As mentioned, the
Zweckmäßig ist der Messerhalter 5 bzw. der Messerkopf 5', an dem, wie aus Fig. 1, 2 und 7 erkennbar, auch ohne weiteres noch ein kleines Glasschneidemesser 19, wie dargestellt, angeordnet werden kann, mit einem Anschlußadapter 16 versehen, mit dem der ganze Messerkopf 5' auswechselbar einem geeigneten Messergriff 20 zugeordnet werden kann.The
