Description

Die Erfindung bezieht sich auf ein Hand-Austraggerät gemäss Oberbegriff von Patentanspruch 1. Ein solches Gerät ist aus der EP-A-236 129 bekannt, wobei die Kartusche einerseits in eine röhrenförmige Halterung eingelegt und durch einen schwenkbaren Bügel gehalten ist. Diese Konstruktion bedingt, dass für jede Kartuschengrösse eine angepasste Halterung verwendet werden muss und ausserdem einen recht hohen Materialaufwand für den langen Bügel. Ausserdem kann der Verschluss am Kartuschenauslassende das Durchbiegen des Verbindungsflansches nicht wirksam verhindern.The invention relates to a hand discharge device according to the preamble of claim 1. Such a device is known from EP-A-236 129, the cartridge being inserted into a tubular holder on the one hand and held by a pivotable bracket. This design means that an adapted holder must be used for each cartridge size and also a very high amount of material for the long bracket. In addition, the closure at the cartridge outlet end cannot effectively prevent the connection flange from bending.

Ausserdem können bei Handgeräten für Kartuschen mit Zweikomponentenmassen bei Betätigung des Abzughebels relativ grosse Kräfte auftreten, die dazu führen können, dass nicht nur die beiden Kartuschen aufgebläht werden, sondern auch der die beiden Zylinder der Kartusche verbindende Flansch durchgebogen wird. Beim Loslassen des Abzughebels ergibt sich aus der Rückkehr des Flansches in die Ausgangslage ein zusätzlicher Druck auf die Füllmasse und unterstützt deren Tendenz auszufliessen. Daher ist die Verhinderung der Flansch-Durchbiegung ein wichtiger Faktor, damit Austraggeräte präzise arbeiten können.In addition, in the case of hand-held devices for cartridges with two-component compositions, relatively large forces can occur when the trigger is actuated, which can result in not only the two cartridges being inflated, but also the flange connecting the two cylinders of the cartridge being bent. When the trigger is released, the return of the flange to the starting position results in additional pressure on the filling compound and supports its tendency to flow out. Prevention of flange deflection is therefore an important factor for discharge devices to work precisely.

Ferner gibt es Kartuschensicherungen, die den Flansch am Handgerät allseitig umfassen und die aus einer als Einzelstück ausgebildete Schnappeinrichtung bestehen, die auf einer Seite den Flansch der Doppelkartusche und auf der anderen Seite die Hinterseite des Hangerätes umfasst und dort einrastbar befestigt ist. Da diese Schnappeinrichtung als Einzelteil ausgebildet ist, besteht die Gefahr, dass die Benutzer dieses Teil verlegen oder bewusst nicht gebrauchen, um Zeit zu gewinnen, wodurch unter Umständen ein sauberes Arbeiten mit dem Handgerät nicht mehr gewährleistet ist.There are also cartridge fuses that encompass the flange on the handheld device on all sides and that consist of a snap-in device designed as a single piece that encompasses the flange of the double cartridge on one side and the rear of the pendant device on the other side and is snap-fastened there. Since this snap device is designed as a single part, there is a risk that the users misplace or deliberately do not use this part in order to save time, which may result clean working with the handheld device is no longer guaranteed.

Es ist vom obigen Stand der Technik ausgehend Aufgabe der vorliegenden Erfindung ein Handgerät zu schaffen, dessen Sicherungsmittel das Durchbiegen des Verbindungs-Flansches wirksam verhindern, einen kleinen Materialaufwand benötigen und nicht verlegt werden können. Diese Aufgabe wird mit dem in Anspruch 1 definierten Handgerät gelöst.Based on the above prior art, it is an object of the present invention to provide a hand-held device whose securing means effectively prevent the connection flange from bending, require a small amount of material and cannot be relocated. This object is achieved with the hand-held device defined in claim 1.

Vom in Fig. 1 dargestellten, vorbekannten Handgerät sind nur die wesentlichen Teile gezeichnet, die für das Verständnis der Erfindung notwendig sind. Dabei ist von der Doppelkartusche 1 nur das Endteil mit dem Flansch 2 dargestellt, wobei aus der Figur hervorgeht, dass der rechts eingezeichnete Zylinder 3 beispielsweise einen kleineren Durchmesser aufweist als Zylinder 4. Dabei kann das Verhältnis der Zylinderdurchmesser von 1:1 bis 1:10 variieren. Das Handgerät 5 weist einen Griff 6 und einen Abzughebel 7 auf, der über einen Uebersetzungsmechanismus zwei Stössel antreibt, deren Druckstücke 8 und 9 die Auspresskolben in den Zylindern der Kartusche betätigen. Die vordere, der Kartusche zugewandte Seite des Handgerätes weist einen Kartuschenhalterrand 10 auf, in den der Flansch der Kartusche gesteckt werden kann. Die beiden Seiten 11 und 12 der Halterung enthalten je einen Schlitz 13, während die untere Seite 14 zwei bogenförmige Ausschnitte 15 und 16 aufweist, auf dem mindestens einer der beiden Zylinder der Kartusche aufliegt und hinter dem die untere Seite des Flansches 2 gefasst wird. Das gleiche gilt sinngemäss für pneumatisch oder elektrisch betriebene Austraggeräte.Of the known hand-held device shown in FIG. 1, only the essential parts are drawn which are necessary for understanding the invention. Here, only the end part of the double cartridge 1 is shown with the flange 2, the figure showing that the cylinder 3 shown on the right has a smaller diameter than cylinder 4, for example. The ratio of the cylinder diameters can be from 1: 1 to 1:10 vary. The hand-held device 5 has a handle 6 and a trigger 7, which drives two plungers via a translation mechanism, the pressure pieces 8 and 9 of which actuate the squeezing pistons in the cylinders of the cartridge. The front side of the hand-held device facing the cartridge has a cartridge holder edge 10 into which the flange of the cartridge can be inserted. The two sides 11 and 12 of the holder each contain a slot 13, while the lower side 14 has two arcuate cutouts 15 and 16, on which at least one of the two cylinders of the cartridge rests and behind which the lower side of the flange 2 is gripped. The same applies analogously to pneumatically or electrically operated discharge devices.

Aus obigem geht hervor, dass die Kartusche, resp. deren Flansch an drei Seiten gehalten ist. Wie bereits in der Einleitung festgestellt worden ist, ist oftmals eine solche dreiseitige Einfassung des Kartuschenflansches nicht genug, um ein Durchbiegen desselben beim Austragen zu verhindern. Die bekannte, bügelförmige Sicherung, die einerseits den Flansch und andererseits das Gerätegehäuse oben umfasst und den Flansch am Gehäuse befestigt, hat den Nachteil, dass dieser Bügel leicht verloren oder verlegt werden kann.From the above it can be seen that the cartridge, resp. whose flange is held on three sides. As has already been stated in the introduction, such a three-sided edging of the cartridge flange is often not enough to prevent the cartridge flange from bending when it is being discharged. The known, bow-shaped fuse, which on the one hand comprises the flange and on the other hand the device housing at the top and fastens the flange to the housing, has the disadvantage that this bracket can easily be lost or misplaced.

Ein erstes Ausführungsbeispiel des erfindungsgemässen Gerätes 17 nach Fig. 2 weist eine Sicherungsklappe 18 auf, die an der Oberseite des Gehäuses 19 des Gerätes angelenkt ist. Die Sicherungsklappe 18 weist an einem Schenkel eine Verdickung 20 auf, die als Gelenk dient. Wahlweise dient ein oberer Schenkel 21 oder 22 als Griffteil, um die Sicherungsklappe ver- oder entriegeln zu können, während ein weiterer, kurzer Schenkel 23 als Verschlussteil ausgebildet ist, um die Oberseite 24 des Flansches 2 der Doppelkartusche zu hintergreifen. Das Gelenk 20 befindet sich in einer Ausnehmung 25 des Gehäuses 19 in der eine Feder 26 angeordnet ist, die auf dieses Gelenk wirkt. Zwischen dem Gelenk 20 und dem Griffteil weist die Sicherungsklappe kartuschenseitig eine Ausnehmung 20a und das Gehäuse eine entsprechende Schulter 19a auf, um die Klappe zurückzuhalten. Dabei wirkt die Feder auf zwei Noppen 27 am Gelenk, denen eine Einbuchtung 28 im freien Schenkel der Feder entspricht, wodurch die Sicherungsklappe eine definierte Verriegelungs-und Oeffnungsstellung erhält.A first exemplary embodiment of the device 17 according to the invention according to FIG. 2 has a securing flap 18, which is on the top of the housing 19 of the device is articulated. The securing flap 18 has a thickening 20 on one leg, which serves as a joint. Optionally, an upper leg 21 or 22 serves as a handle part in order to be able to lock or unlock the securing flap, while a further, short leg 23 is designed as a closure part to engage behind the upper side 24 of the flange 2 of the double cartridge. The joint 20 is located in a recess 25 of the housing 19 in which a spring 26 is arranged which acts on this joint. Between the joint 20 and the handle part, the securing flap has a recess 20a on the cartridge side and the housing has a corresponding shoulder 19a in order to retain the flap. The spring acts on two knobs 27 on the joint, to which an indentation 28 in the free leg of the spring corresponds, as a result of which the securing flap is given a defined locking and opening position.

In Fig. 3 ist eine Ausführungsvariante zu Fig. 2 dargestellt, in dem das Handgerät 29 statt einer im Profil U-förmigen Blattfeder 26 eine Druckfeder 30 aufweist, die teilweise in einer verschiebbaren Büchse 31 angeordnet ist um diese gegen das Gelenk 32 an der Sicherungsklappe 33 zu stossen. Auch dieses Ausführungsbeispiel weist eine Ausnehmung 32a beim Gelenk und eine entsprechende Schulter 19a im Gehäuse auf. Das Gelenk weist zwei ebene Flächen 34 und 35 auf, um die Sicherungsklappe in den beiden Endlagen definiert zu halten. Die Arbeits- und Wirkungsweise bei den Sicherungsklappen 18 oder 33 ist für beide die gleiche und beide haben eine definierte Absperr- und Oeffnungsposition und sind im Stande, die Doppelkartusche auch bei hohen Austragsdrücken festzuhalten. Es ist auch möglich, die Druckfeder 30a stärker auszuführen und gemäss Fig. 3a die Büchse auf ein zylindrisches Gelenk 32b wirken zu lassen, so dass die Bewegung der Sicherungsklappe 33a nur durch die Reibung fixiert wird.3 shows an embodiment variant of FIG. 2, in which the hand-held device 29 has a compression spring 30 instead of a leaf spring 26 with a U-shaped profile, which is partially arranged in a displaceable sleeve 31 around it against the joint 32 on the securing flap 33 to come across. This exemplary embodiment also has a recess 32a in the joint and a corresponding shoulder 19a in the housing. The joint has two flat surfaces 34 and 35 in order to hold the securing flap in a defined manner in the two end positions. The working and mode of operation of the safety flaps 18 or 33 is the same for both and both have a defined shut-off and opening position and are able to hold the double cartridge in place even at high discharge pressures. It is also possible to make the compression spring 30a stronger and to let the bush act on a cylindrical joint 32b according to FIG. 3a, so that the movement of the securing flap 33a is only fixed by the friction.

Das Handgerät 36 gemäss Fig. 4 weist eine Sicherungsklappe 37 auf, deren Verschlussschenkel 38 der gleiche ist wie bei den vorhergehenden Ausführungsbeispielen, die aber nur einen Griffteil 39 aufweist. Das Gelenk 40 an der Sicherungsklappe befindet sich in diesem Ausführungsbeispiel nicht direkt am Schenkel der Sicherungklappe, sondern an einem parallel zu den Kartuschen und Stössel angeordneten Steg 41. Das Gelenk 40 ist mit einer Zugfeder 42 beaufschlagt, dessen anderes Ende am Gehäuse angelenkt ist. Beim Oeffnen der Sicherungsklappe wird diese durch die Zugfeder zurückgezogen und gesichert.4 has a securing flap 37, the locking leg 38 of which is the same as in the previous exemplary embodiments, but which has only one handle part 39. In this exemplary embodiment, the joint 40 on the securing flap is not located directly on the leg of the securing flap, but on a web 41 arranged parallel to the cartridges and plunger. The joint 40 is acted upon by a tension spring 42, the other end of which is articulated on the housing. When the safety flap is opened, it is pulled back and secured by the tension spring.

Das Handgerät 43 gemäss Fig. 5 ist eine platzsparende Ausführungsvariante zum obigen gemäss Fig. 4, in dem der Steg 44 ausserhalb des Gehäuses angeordnet ist und an seinem Ende ein im Querschnitt U-förmiges Endstück 45 aufweist, das an einer durchgehenden Achse 46 in einem Schlitz 47 im Gehäuse läuft. Die Achse 46 ist mit einer im Gehäuse angeordneten Druckfeder 48 beaufschlagt, die auch die Aufgabe hat, die Sicherungsklappe 49 in eine definierte Offenstellung zu bringen und zu halten.5 is a space-saving embodiment of the above according to FIG. 4, in which the web 44 is arranged outside the housing and at its end has an end piece 45 which is U-shaped in cross section and has a continuous axis 46 in one Slot 47 in the housing runs. The axis 46 is acted upon by a compression spring 48 arranged in the housing, which also has the task of bringing the securing flap 49 into a defined open position and holding it.

Das Handgerät 50 gemäss den Fig. 6 und 7 weist eine Sicherungsklappe 51 auf. Die Sicherungsklappe 51 ist im Querschnitt etwa U-förmig aufgebaut und weist ein Griffteil 52 sowie den Verschlussteil 53 zum Hintergreifen des Flansches 2 der Doppelkartusche auf. Am Griffteil 52 schliessen sich die Schenkel 69 mit den Gelenkzapfen 54 an (Fig. 7), die in entsprechende Nuten 70 in einer Ausnehmung 55 im Gehäuse des Gerätes angeordnet sind und einen Absatz 56 hintergreifen, der das Herausfallen der Klappe verhindert. Je eine Blattfeder 67 ist zwischen dem Gehäuse 68 und den Schenkel 69 der Sicherungsklappe 51 angeordnet. Um die Sicherungsklappe zu entriegeln wird diese am Griffteil zuerst bis zum Anschlag 56 heraufgezogen, wodurch das Verschlussteil 53 den Flansch freigibt und die Feder 67 den Verschlussteil in die Offenstellung bringt.The handheld device 50 according to FIGS. 6 and 7 has a securing flap 51. The securing flap 51 has an approximately U-shaped cross section and has a grip part 52 and the closure part 53 for engaging behind the flange 2 of the double cartridge. The legs 69 are connected to the handle part 52 with the pivot pins 54 (FIG. 7), which are arranged in corresponding grooves 70 in a recess 55 in the housing of the device and engage behind a shoulder 56 which prevents the flap from falling out. One leaf spring 67 each is arranged between the housing 68 and the leg 69 of the securing flap 51. In order to unlock the safety flap, it is first pulled up to the stop 56 on the handle part, as a result of which the closure part 53 releases the flange and the spring 67 brings the closure part into the open position.

Um das Einführen der Sicherungsklappe hinter den Absatz 56 zu erleichtern, kann es zweckmässig sein, die beiden Schenkel 69 mit je einem Schlitz 69a zu versehen, um deren Elastizität zu erhöhen.In order to facilitate the insertion of the securing flap behind the shoulder 56, it may be expedient to provide the two legs 69 with a slot 69a each, in order to increase their elasticity.

Während bei allen bis jetzt beschriebenen Ausführungsbeispielen die Drehachse der Sicherungsklappe quer zur Erstreckung der Zylinder und der Stössel angeordnet war, ist die Achse 58 beim Handgerät 57 gemäss den Fig. 8 und 9 parallel zu den Kartuschen und Stösseln angeordnet. Die Sicherungsklappe 59 weist an dem dem Gelenk 60 mit der Drehachse 58 entgegengesetzten Ende ein Griffteil 61 und einen elastischen Riegel 62 auf, der in einer Ausnehmung 63 im Gehäuse einrastbar ist. Wie insbesondere aus Fig. 9 hervorgeht, ist die Sicherungsklappe im Schnitt U-förmig ausgebildet, wobei der eine Schenkel vom Verschlussteil 66 gebildet wird und der andere Schenkel 64 in einer Nut 65 das Gehäuse hintergreift, wodurch eine starke Verriegelung der Doppelkartusche erzielt wird.While in all of the exemplary embodiments described so far, the axis of rotation of the securing flap was arranged transversely to the extent of the cylinders and the plunger, the axis 58 in the handheld device 57 according to FIGS. 8 and 9 is arranged parallel to the cartridges and plungers. The securing flap 59 has, at the end opposite the joint 60 with the axis of rotation 58, a grip part 61 and an elastic latch 62 which can be snapped into a recess 63 in the housing. As can be seen in particular from FIG. 9, the securing flap is U-shaped in section, one leg being formed by the closure part 66 and the other leg 64 engaging behind the housing in a groove 65, as a result of which a strong locking of the double cartridge is achieved.

Allen Sicherungsklappen gemeinsam ist, dass sie am Gehäuse gelenkig befestigt sind und nicht versehentlich verloren werden können und dass sie ausgebildet sind, die Doppelkartusche fest an dem Gehäuse zu befestigen.All safety flaps have in common that they are articulated to the housing and cannot be accidentally lost and that they are designed to firmly fix the double cartridge to the housing.
