Description

Die Erfindung betrifft einen Klebebandabroller mit einer in einem Gehäuse angeordneten Aufnahme für eine Klebebandrolle, mit einem im Abstand von der Aufnahme am Gehäuse angeordneten einseitig durch ein Umlenkelement begrenzten Austrittsspalt für das abzurollende Klebeband und mit einer auf der Seite des Umlenkelements in seitlichem Abstand vom Austrittsspalt angeordneten Schneidklinge zum Abtrennen eines überstehenden Klebebandstücks, wobei das Umlenkelement beim Abtrennen des überstehenden Klebebandstücks entgegen der Kraft einer Feder in Richtung Schneidklinge bewegbar ist, und wobei die Schneidklinge in Wirkverbindung mit dem Umlenkelement steht und unter dessen Einwirkung zwischen einer eingezogenen Endstellung und einer mit ihrer Schneide über das Gehäuse überstehenden Endstellung bewegbar ist.The invention relates to a Klebebandabroller with a in a housing arranged receptacle for a roll of adhesive tape, with a distance from the recording on the housing arranged on one side by a deflecting element limited exit gap for the tape to be unrolled and with a on the side of the deflecting element at a lateral distance from the outlet gap arranged cutting blade for separating a protruding piece of adhesive tape, wherein the deflecting element when separating the protruding Adhesive tape piece against the force of a spring in Direction cutting blade is movable, and wherein the cutting blade is in operative connection with the deflecting element and under its action between a retracted end position and one with her Cutting edge on the housing protruding end position is movable.

Klebebandabroller dieser Art sind bekannt (WO 95/23108). Der Abstand zwischen dem Austrittsspalt und der Schneidklinge sorgt dafür, daß immer ein ausreichendes Stück des Klebebandes aus dem Gehäuse herausragt, daß das Klebeband also nicht in das Gehäuse zurück gleiten kann. Bei den bekannten Klebebandabrollern dieser Art wird es als nachteilig empfunden, daß beim bestimmungsgemäßen Gebrauch die Gefahr einer Verletzung an der Schneidklinge besteht.Tape dispensers of this type are known (WO 95/23108). The distance between the exit slit and the cutting blade ensures that always a sufficient piece of the adhesive tape protrudes from the housing, that the tape can not slide back into the case. In the known Klebebandabrollern this type, it is considered disadvantageous that when used as intended the risk of injury to the Cutting blade exists.

Ausgehend hiervon liegt der Erfindung die Aufgabe zugrunde, einen Klebebandabroller der eingangs angegebenen Art zu entwickeln, der ohne eine Verletzungsgefahr leicht handhabbar ist. Proceeding from this, the object of the invention is an adhesive tape dispenser develop the type specified, the without a Risk of injury is easy to handle.

Zur Lösung dieser Aufgabe werden die im Patentanspruch 1 angegebenen Merkmale vorgeschlagen:To solve this problem specified in claim 1 Features proposed:

Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den abhängigen Ansprüchen.Advantageous embodiments and further developments of the invention result from the dependent claims.

Der erfindungsgemäßen Lösung liegt primär der Gedanke zugrunde, daß das Umlenkelement beim Abtrennen des überstehenden Klebebandstücks entgegen der Kraft einer Feder in Richtung Schneidklinge bewegbar ist und daß die Schneidklinge in Wirkverbindung mit dem Umlenkelement steht und unter dessen Einwirkung zwischen einer eingezogenen Endstellung und einer mit ihrer Schneide über das Gehäuse überstehenden Endstellung bewegbar ist, wobei das Umlenkelement am freien Ende einer am Gehäuse eingespannten Federzunge angeordnet und die Federzunge zweckmäßig über ein federndes Koppelglied mit der Schneidklinge gekoppelt ist. Mit den erfindungsgemäßen Maßnahmen ist somit gewährleistet, daß die Schneidklinge nur dann selbsttätig aus ihrer geschützten Position herausbewegt wird, wenn ein überstehendes Klebebandstück abgetrennt wird. Fehlbedienungen, die zu Verletzungen führen könnten, sind daher weitgehend ausgeschlossen.The inventive solution is primarily based on the idea that the Counteracting element when separating the protruding piece of adhesive tape the force of a spring in the direction of the cutting blade is movable and that the cutting blade is in operative connection with the deflecting element and under its action between a retracted end position and a with its cutting edge can be moved beyond the housing projecting end position, wherein the deflecting element at the free end of a clamped to the housing Placed spring tongue and the spring tongue expediently via a resilient Coupling link is coupled to the cutting blade. With the invention Measures is thus ensured that the cutting blade only then is automatically moved out of its protected position, if a protruding Piece of adhesive tape is separated. Operating errors leading to injuries are therefore largely excluded.

Eine bevorzugte Ausgestaltung der Erfindung sieht vor, daß die Schneidklinge in einer Schubführung des Gehäuses angeordnet ist.A preferred embodiment of the invention provides that the cutting blade is arranged in a push guide of the housing.

Vorteilhafterweise ist das federnde Koppelglied als Biegefeder ausgebildet, die an ihrem einen Ende in die Schubführung eingreift wo es die Schneidklinge trägt und mit ihrem anderen Ende im Abstand vom Umlenkelement und zweckmäßig auch von der Einspannstelle mit der Federzunge verbunden ist.Advantageously, the resilient coupling member is formed as a bending spring, which engages at its one end in the push guide where it is the cutting blade carries and with its other end at a distance from the deflector and expediently also connected by the clamping with the spring tongue is.

Da die Schneidklinge nur einen definierten Verschiebeweg benötigt, um ihre Wirkung zu entfalten, ist es vorteilhaft, wenn der Bewegungsweg des Umlenkelements durch einen Gehäuseanschlag begrenzt ist.Because the cutting blade needs only a defined displacement to their To unfold effect, it is advantageous if the movement path of the deflecting element is limited by a housing stop.

Aus fertigungstechnischen Gründen ist es von Vorteil, wenn die Federzunge und das federnde Koppelglied als einstückiges Formteil vorzugsweise aus Kunststoff ausgebildet sind. Die Schneidklinge kann dabei im Bereich des freien Endes des federnden Koppelglieds in das Formteil eingebettet sein.For manufacturing reasons, it is advantageous if the spring tongue and preferably the resilient coupling member as a one-piece molded part Plastic are formed. The cutting blade can be in the range of be embedded in the molded part free end of the resilient coupling member.

Eine bevorzugte Ausgestaltung der Erfindung sieht vor, daß das Gehäuse aus zwei Gehäuseschalen besteht, die um eine zur Abrollachse des Klebebands parallele Schwenkachse gegeneinander verschwenkbar sind und die in ihrer Schließstellung lösbar miteinander verrastbar sind. Die beiden Gehäuseschalen bilden dabei zweckmäßig an ihren schwenkachsennahen Enden eine gemeinsame Stellfläche und begrenzen an ihren anderen Enden gemeinsam den bezüglich der Stellfläche schräg nach oben weisenden Austrittsspalt wobei die Schneidklinge an einer der Gehäuseschalen bezüglich der Stellfläche schräg oberhalb des Austrittsspalts angeordnet ist. Die Schneide der Schneidklinge ist durch eine zum Austrittsspalt parallele Schlitzöffnung der betreffenden Gehäuseschale hindurch verschiebbar. Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, daß die an der schneidklingenseitigen Gehäuseschale gelagerte Federzunge mit ihrem stirnseitigen, das Umlenkelement tragenden Ende in einen randoffenen Austrittskanal der anderen Gehäuseschale spaltbegrenzend eingreift.A preferred embodiment of the invention provides that the housing consists of two housing shells around one to the rolling axis of the adhesive tape parallel pivot axis are mutually pivotable and the in their closed position are releasably locked together. The two housing shells thereby form expediently at their ends near the pivot axis a common footprint and limit at their other ends together with respect to the footprint obliquely upward-pointing outlet gap wherein the cutting blade with respect to one of the housing shells the footprint is arranged obliquely above the outlet gap. The The cutting edge of the cutting blade is parallel to the exit slit Slot opening of the relevant housing shell slidable. A advantageous embodiment of the invention provides that at the cutting blade side Housing shell mounted spring tongue with its frontal, the deflection end bearing in an open-edge outlet channel of engages other housing shell gap-limiting.

Vorteilhafterweise ist die Aufnahme für die Klebebandrolle als an einer der Gehäuseschalen drehfest fixierbare Steckachse ausgebildet, die zweckmäßig auf über die eine Gehäuseschale überstehende Haltezungen drehfest aufsteckbar ist. Die Steckachse greift vorteilhafterweise mit ihren unrunden Enden formschlüssig in eine entsprechend unrunde Öffnung zwischen den beiden Gehäuseschalen ein.Advantageously, the receptacle for the roll of adhesive tape as at one of Housing shells rotatably fixable stub axle formed, the appropriate on about the housing shell projecting retaining tongues rotatably is pluggable. The thru-axle advantageously engages with its non-circular Ends form-fitting in a corresponding non-circular opening between the two housing shells.

Der in der Zeichnung dargestellte Klebebandabroller weist ein aus zwei Gehäuseschalen 10, 12 zusammengesetztes Gehäuse auf, in welchem eine Steckachse 14 zur Aufnahme einer Klebebandrolle 16 angeordnet ist. In seinem oberen Bereich weist das Gehäuse einen durch ein Umlenkelement 18 begrenzten Austrittsspalt 20 für das abzurollende Klebeband 22 sowie eine auf der Seite des Umlenkelements 18 im Abstand vom Austrittsspalt 20 angeordnete Schneidklinge 24 zum Abtrennen eines überstehenden Klebebandstücks 62 auf. Die beiden Gehäuseschalen 10, 12 bilden an ihrem unteren Ende eine durch ein aufgerastetes Bodenteil 26 gebildete Stellfläche und sind um eine zur Abrollachse der Klebebandrolle 16 parallele Schwenkachse 28 zum Öffnen des Gehäuses gegeneinander verschwenkbar und in ihrer in Fig. 1 und 3 gezeigten Schließstellung über Rastelemente 30 miteinander verrastbar. Die Rastverbindung 30 kann durch federelastisches Gegeneinanderdrücken der an den Seitenwänden 32 der Gehäuseschale 12 angeordneten geriffelten Griffbereiche 34 gelöst werden. Wie aus Fig. 1 und 3 zu sehen ist weist der Austrittsspalt 20 für das Klebeband 22 schräg nach oben. The adhesive tape dispenser shown in the drawing has one of two housing shells 10, 12 assembled housing, in which a Thru axis 14 is arranged for receiving a roll of adhesive tape 16. In his Upper area, the housing has a through a deflection element 18th limited exit slit 20 for the unwinding tape 22 and a on the side of the deflecting element 18 at a distance from the outlet gap 20 arranged Cutting blade 24 for separating a protruding piece of adhesive tape 62 on. The two housing shells 10, 12 form at their lower End of a formed by a ratcheted bottom part 26 footprint and are about an axis parallel to the Abrollachse the adhesive tape roll 16 pivot axis 28 for opening the housing against each other and pivoted in their in Fig. 1 and 3 shown closed position via locking elements 30 with each other latched. The latching connection 30 can by resiliently pressing against each other arranged on the side walls 32 of the housing shell 12 fluted handle portions 34 are solved. As is apparent from FIGS. 1 and 3 see, the exit slit 20 for the adhesive tape 22 obliquely upward.

Er ist durch einen Austrittskanal 36 in der Gehäuseschale 12 und durch das Umlenkelement 18 begrenzt. Die Schneidklinge 24, die bei dem gezeigten Ausführungsbeispiel eine zackenförmige Schneide 38 aufweist, befindet sich in einer zum Austrittsspalt 20 parallelen Schlitzöffnung 40 der Gehäuseschale 10.He is through an outlet channel 36 in the housing shell 12 and through the Deflecting element 18 limited. The cutting blade 24, which in the shown Embodiment has a serrated edge 38 is located in a parallel to the outlet gap 20 slot opening 40 of the housing shell 10th

Die Steckachse 14 zur Aufnahme der Klebebandrolle 16 ist auf über die Gehäuseschale 12 quer überstehende Haltezungen 42 drehfest aufsteckbar. Sie greift mit ihren unrunden Enden 44 formschlüssig in die zwischen den beiden Gehäuseschalen 10, 12 gebildete zwickelartige Öffnung 46 ein. Um auch Klebebandrollen mit kleinerem Rolleninnendurchmesser aufnehmen zu können, sind an den einander zugewandten Innenflächen der Haltezungen zylindrische Halteringe 70 angeformt, auf die die Klebebandrolle mit ihren offenen Enden aufsteckbar ist. Die Haltezungen 42 sind zu diesem Zweck federnd gegeneinander aufspreizbar.The thru-axle 14 for receiving the adhesive tape roll 16 is on over the housing shell 12 transversely projecting retaining tongues 42 rotatably attachable. It engages with its non-round ends 44 form-fitting in between the two housing shells 10, 12 formed gore-like opening 46 a. Around also tape rolls with a smaller inner diameter roll record can, are at the mutually facing inner surfaces of the retaining tongues cylindrical retaining rings 70 integrally formed on the tape roll with their open ends can be plugged. The retaining tongues 42 are for this purpose resiliently spreadable against each other.

Wie insbesondere aus Fig. 2 und 3 zu ersehen ist, ist das Umlenkelement 18 durch das verdickte freie Ende einer mit seinem anderen Ende 47 an Einspannstellen 48 der Gehäuseschale 10 eingespannten Federzunge 50 gebildet. Im Abstand vom Umlenkelement 18 ist an der Federzunge 50 weiter ein als Biegefeder ausgebildetes federndes Koppelglied 52 angeformt, das mit seinem die Schneidklinge 24 tragenden Ende 54 in der Außenwand 58 der Gehäuseschale 10 abgestützt und in Richtung des Pfeils 60 nach Art einer Schubführung geführt ist. Wenn somit beim Abrollen und anschließenden Abschneiden des Klebebands 22 das abzutrennende Bandende 62 in Richtung des Pfeils 64 gezogen wird, wird das Umlenkelement 18 unter Aufweitung des Austrittsspalts 20 bis zum Anschlag 66 entgegen der Federkraft der Federzunge 50 und des federnden Koppelglieds 52 mitgenommen. Dabei kommt es zu einer Verschiebung des Koppelglieds 52 in Richtung des Pfeils 60, die dazu führt, daß die Schneidklinge 24 mit ihrer Schneide 38 aus der in Fig. 3 gezeigten, in das Gehäuse zurückgezogenen Position in Richtung des Pfeils 60 durch die Schlitzöffnung 40 nach außen hindurchtritt und dort zum Abschneiden des überstehenden Bandstücks 62 verwendet werden kann. Wenn das Bandstück abgetrennt ist, gelangt das verbleibende Band unter der Einwirkung des von der Federkraft zurück schwingenden Umlenkelements 18 wieder in die in Fig. 1 und 3 gezeigte Ausgangslage. Gleichzeitig wird hierbei die Schneide 38 der Schneidklinge 24 in ihre geschützte Position in der Gehäuseschale 10 zurück verschoben. Die Federzunge 50 und das mit dieser verbundene federnde Koppelglied 52 bilden somit eine Art Koppelgetriebe, dessen Bewegung beim Abtrennen des überstehenden Klebebandstücks entgegen der Kraft einer Feder bewegbar ist. Die Schneidklinge besteht zweckmäßig aus einem gehärteten Stahl, während die übrigen Bauteile als Kunststoffformteile ausgebildet sein können.As can be seen in particular from FIGS. 2 and 3, the deflecting element 18 through the thickened free end of one with its other end 47 at clamping points 48 of the housing shell 10 clamped spring tongue 50 is formed. At a distance from the deflecting element 18 is on the spring tongue 50 on formed as a bending spring springy coupling member 52, the with its cutting blade 24 bearing end 54 in the outer wall 58th the housing shell 10 is supported and in the direction of the arrow 60 according to Art a push guide is guided. If so when unrolling and then Cutting off the adhesive tape 22 the band end 62 to be cut off Direction of the arrow 64 is pulled, the deflecting element 18 is under expansion the exit gap 20 up to the stop 66 against the spring force the spring tongue 50 and the resilient coupling member 52 taken. there There is a shift of the coupling member 52 in the direction of Arrow 60, which causes the cutting blade 24 with its cutting edge 38 from the position shown in Fig. 3, withdrawn into the housing in the direction of the arrow 60 passes through the slot opening 40 to the outside and used there to cut off the projecting piece of tape 62 can. When the piece of tape is severed, the remaining tape passes under the action of the deflecting element swinging back by the spring force 18 again in the starting position shown in Fig. 1 and 3. simultaneously In this case, the cutting edge 38 of the cutting blade 24 is protected in their Position in the housing shell 10 moved back. The spring tongue 50 and the associated with this resilient coupling member 52 thus form a Art coupling gear whose movement when separating the protruding Adhesive tape piece is movable against the force of a spring. The cutting blade Conveniently consists of a hardened steel, while the rest Components may be formed as plastic moldings.

Zusammenfassend ist folgendes festzuhalten: Die Erfindung bezieht sich auf einen Klebebandabroller mit einer in einem Gehäuse 10, 12 angeordneten Aufnahme 14 für eine Klebebandrolle 16. Im Abstand von der Aufnahme 14 ist am Gehäuse 10, 12 ein Austrittsspalt 20 für das abzurollende Klebeband angeordnet, der einseitig durch ein Umlenkelement 18 begrenzt ist.
