Description

Die Erfindung betrifft ein Auftragsgerät nach dem Oberbegriff des Anspruchs 1.The invention relates to an application device according to the preamble of claim 1.

Ein derartiges Auftragsgerät ist aus der CH-A 167 533 bzw. aus der CH-A 167 534 bekannt. Bei diesen bekannten Auftragsgeräten handelt es sich um Minenbleistifte. Die Minen solcher Minenbleistifte bestehen aus Graphit und Ton, wobei in einem Brennvorgang eine Härtung der Mine erfolgt. Für kosmetische Anwendungen sind derartige gebrannte Minen ungeeignet.Such an application device is known from CH-A 167 533 and from CH-A 167 534. These known applicators are mine pencils. The refills of such refill pencils consist of graphite and clay, the refining hardening of the refill. Such burnt leads are unsuitable for cosmetic applications.

Die GB-A 956 651 offenbart ein Auftragsgerät, bei dem eine Mine aus einer streichfähigen Masse zur Anwendung gelangen kann, die in einem Extrusionsvorgang hergestellt wird und die an einem am Vorderende einer Gewindespindel vorgesehenen Schiebeorgan befestigt ist. Ein Griffteil ist bei diesem Auftragsgerät mit einem Schraubteil dadurch verbunden, dass das Griffteil an seinem dem Schraubteil zugewandten Ende einen eingebördelten Rand mit einer Öffnung und dass das Schraubteil an seinem dem Griffteil zugewandten Endabschnitt aufgeweitet ist. Infolge dieser Ausbildung ist es bei diesem Auftragsgerät nicht möglich, das Schraubteil problemlos vom Griffteil zu entfernen. Ausserdem ist dieses Auftragsgerät nur für die Verwendung von extrudierten Minen vorgesehen bzw. geeignet.GB-A 956 651 discloses an application device in which a refillable paste can be used which is produced in an extrusion process and which is fastened to a sliding element provided at the front end of a threaded spindle. A grip part is in this applicator connected to a screw part in that the handle part at its end facing the screw part has a crimped edge with an opening and that the screw part is widened at its end section facing the handle part. As a result of this training, it is not possible with this applicator to remove the screw part from the handle part without problems. In addition, this applicator is only intended or suitable for the use of extruded leads.

Der Erfindung liegt die Aufgabe zugrunde, ein Auftragsgerät der eingangs genannten Art zu schaffen, bei dem das Griffteil wahlweise mit Schraubteilen kombiniert werden kann, die mit extrudierten oder eingegossenen Minen versehen sind, wobei die Gewindespindel und die Gewindehülse sowie insbes. das Schiebeorgan für die Mine unabhängig von dem zur Anwendung gelangenden Schraubteil stets gleich ausgebildet sind.The invention has for its object to provide an applicator of the type mentioned, in which the handle part can optionally be combined with screw parts that are provided with extruded or cast leads, the threaded spindle and the threaded sleeve and esp. The sliding element for the mine are always the same regardless of the screw part used.

Diese Aufgabe wird bei einem Auftragsgerät der eingangs genannten Art erfindungsgemäss durch die Merkmale des kennzeichnenden Teiles des Anspruchs 1 gelöst. Bevorzugte Weiterbildungen des erfindungsgemässen Auftragsgerätes sind in den Unteransprüchen gekennzeichnet.This object is achieved according to the invention in an application device of the type mentioned at the outset by the features of the characterizing part of claim 1. Preferred developments of the application device according to the invention are characterized in the subclaims.

Das Schiebeorgan besteht vorzugsweise aus einem Kunststoffmaterial. Dadurch, dass der Kolben und die den Kolben umschliessende Kolbenhülse in einem Spritzgiess-Arbeitsgang mit derartigen Sollbruchstellen ausgebildet wird, dass der Kolben von der Kolbenhülse erst bei der Montage des Schiebeorgans im Auftragsgerät in zwei Teile getrennt wird, die ineinander einrasten, ergibt sich einerseits eine einfache Herstellung desselben und andererseits in besonders vorteilhafter Weise die Möglichkeit, auf dem Griffteil entweder ein Schraubteil in Gestalt einer Minenpatrone oder ein Schraubteil mit einer extrudierten Mine zu befestigen, wobei sowohl die in die Minenpatrone eingegossene Mine als auch die extrudierte Mine mit Hilfe des Schiebeorgans aus dem Vorderende des Schraubteils wunschgemäss ausgeschraubt werden kann.The sliding member is preferably made of a plastic material. The fact that the piston and the piston sleeve surrounding the piston are formed in one injection molding operation with such predetermined breaking points that the piston is only separated from the piston sleeve in two parts when the slide member is installed in the applicator, which snap into one another, results in one simple production of the same and on the other hand, in a particularly advantageous manner Possibility to attach either a screw part in the form of a lead cartridge or a screw part with an extruded lead to the handle part, whereby both the lead cast into the lead cartridge and the extruded lead can be unscrewed from the front end of the lead part as desired using the sliding element.

Bei einer Ausbildung des erfindungsgemässen Auftragsgerätes ist das Minenbehältnis als Minenpatrone ausgebildet, in welche die Mine eingegossen ist. In diesem Fall weist die Minenpatrone an ihrem dem Griffteil zugewandten Endabschnitt eine Ausnehmung mit einem Anschlag auf, durch welchen die Kolbenhülse bei einer axialen Bewegung des Kolbens zum Vorschub der Mine aus der Minenpatrone heraus an einer axialen Mitbewegung gehindert wird. Hierbei erfolgt die Vorschubbewegung der in die Minenpatrone eingegossenen Mine nur durch den Kolben, weil die Kolbenhülse in der den Anschlag aufweisenden Ausnehmung gegen eine axiale Vorschubbewegung gesichert ist. Sobald die in die Minenpatrone eingegossene Mine verbraucht ist, wird die gebrauchte Minenpatrone vom Griffteil entfernt und auf dem Griffteil eine neue Minenpatrone mit einer eingegossenen Mine befestigt. Bei dieser Befestigung einer neuen Minenpatrone ergibt sich eine drehfeste Verbindung der neuen Minenpatrone mit der im Griffteil vorgesehenen Gewindehülse. Bevor auf dem Griffteil eine neue Minenpatrone befestigt wird, ist es erforderlich, den Kolben in die zurückgezogene hintere Endposition zurückzustellen. Das geschieht selbstverständlich noch mit der alten abgebrauchten Minenpatrone.When the application device according to the invention is designed, the mine container is designed as a mine cartridge, into which the mine is cast. In this case, the refill cartridge has at its end section facing the handle part a recess with a stop, by means of which the piston sleeve is prevented from axially moving together with an axial movement of the piston to advance the refill out of the refill cartridge. In this case, the feed movement of the lead cast into the lead cartridge takes place only through the piston, because the piston sleeve is secured in the recess having the stop against an axial feed movement. As soon as the refill poured into the refill cartridge is used up, the used refill cartridge is removed from the grip part and a new refill cartridge with a refilled refill is attached to the grip part. This attachment of a new cartridge leads to a non-rotatable connection of the new cartridge with the threaded sleeve provided in the handle part. Before a new cartridge is attached to the handle, it is necessary to return the piston to the retracted rear end position. Of course, this still happens with the old used cartridge.

Anstelle eines Schraubteiles mit einer eingegossenen Minenpatrone kann auch ein Schraubteil in Kombination mit einer extrudierten Mine zur Anwendung gelangen, wobei das Schraubteil einen zentralen Hohlraum aufweist, in dem die mit dem Kolben verbundene Kolbenhülse axial verschiebbar ist, wobei die Mine mit ihrem hinteren Endabschnitt in der Kolbenhülse angeordnet ist. Diese Ausbildung des Auftragsgerätes unterscheidet sich von der oben beschriebenen Ausbildung des Auftragsgerätes, die eine Minenpatrone als Schraubteil aufweist, dadurch, dass eine extrudierte Mine zur Anwendung gelangt. Bei dieser Ausbildung des Auftragsgerätes kann das Schraubteil am Griffteil verbleiben, so dass nur eine verbrauchte Mine durch eine neue extrudierte Mine ersetzt zu werden braucht. Ein weiterer Unterschied zur weiter oben beschriebenen Ausbildung des Auftragsgerätes mit Minenpatrone und eingegossener Mine besteht darin, dass sich nicht nur der Kolben sondern mit dem Kolben auch die Kolbenhülse bewegt, wenn die Mine verschoben wird. Bei der zuletzt genannten Ausbildung des Auftragsgerätes ist es im Gegensatz zur Ausbildung des Auftragsgerätes mit Minenpatrone und eingegossener Mine möglich, die Mine nicht nur vorzuschieben, sondern auch in das Schraubteil zurückzubewegen.Instead of a screw part with a cast-in lead cartridge, a screw part in combination with an extruded lead can also be used, the Screw part has a central cavity in which the piston sleeve connected to the piston is axially displaceable, the lead being arranged with its rear end section in the piston sleeve. This design of the applicator differs from the design of the applicator described above, which has a cartridge as a screw part, in that an extruded lead is used. With this configuration of the application device, the screw part can remain on the handle part, so that only a used lead needs to be replaced by a new extruded lead. Another difference from the design of the application device with a cartridge and a cast-in lead described above is that not only the piston but also the piston sleeve moves with the piston when the lead is moved. In the latter embodiment of the application device, in contrast to the application device with a cartridge and a cast-in lead, it is possible not only to advance the lead but also to move it back into the screw part.

Bei der Ausbildung des Auftragsgerätes, bei dem eine extrudierte Mine zur Anwendung gelangt, hat es sich als vorteilhaft erwiesen, wenn der zentrale Hohlraum des Schraubteils an seinem Vorderende einen Anschlag für die Kolbenhülse aufweist, und wenn der Kolben in der vorderen Anschlagstellung der Kolbenhülse zum Auswerfen des Minenrestes aus der Kolbenhülse um eine definierte Strecke gegen die Kolbenhülse axial nach vorne bewegbar ist. Durch eine derartige Ausbildung des Auftragsgerätes ergibt sich eine sog. Auswerfautomatik, mit der es einfach möglich ist, den hinteren Endabschnitt der extrudierten Mine aus dem Auftragsgerät durch Drehung des Schraubteils auszuwerfen, der in der Kolbenhülse des Schiebeorgans vorgesehen ist. Das ist möglich, weil der Kolben in der vordersten Stellung des Schiebeorgans noch eine definierte Vorschubbewegung ausführt, während die Kolbenhülse am Anschlag des Schraubteils anliegt und an einer simultanen Vorschubbewegung gehindert wird. Bis zum Erreichen des vorderen Anschlags führen die Kolbenhülse und der Kolben dieselbe Vorschub- bzw. Rückzugbewegung aus, weil die Kolbenhülse mit dem Kolben ausreichend fest verbunden ist. Erst bei Anlage der Kolbenhülse am vorderen Anschlag wird die Verbindungskraft zwischen dem Kolben und der Kolbenhülse durch die weitere Vorschubbewegung des Kolbens aufgehoben.In the design of the application device, in which an extruded mine is used, it has proven to be advantageous if the central cavity of the screw part has a stop for the piston sleeve at its front end, and if the piston is in the front stop position of the piston sleeve for ejection of the rest of the lead can be moved axially forward from the piston sleeve by a defined distance against the piston sleeve. Such a design of the application device results in a so-called automatic ejection mechanism, with which it is easily possible to eject the rear end section of the extruded lead from the application device by rotating the screw part, which is provided in the piston sleeve of the sliding element. This is possible because the piston still executes a defined feed movement in the foremost position of the sliding member, while the piston sleeve lies against the stop of the screw part and is prevented from a simultaneous feed movement. Until the front stop is reached, the piston sleeve and the piston carry out the same advancing or retracting movement because the piston sleeve is connected to the piston sufficiently firmly. The connecting force between the piston and the piston sleeve is only released by the further advancing movement of the piston when the piston sleeve abuts the front stop.

Unabhängig von der Ausbildung des Auftragsgerätes mit einem Schraubteil in Gestalt einer Minenpatrone oder in Gestalt eines Schraubteils zum Verstellen einer extrudierten Mine weist die Gewindehülse vorzugsweise einen hinteren Anschlag für die Kolbenhülse auf. Durch diesen hinteren Anschlag wird die Rückzugbewegung des Schiebeorgans, d.h. insbes. der Kolbenhülse des Schiebeorgans definiert begrenzt, so dass eine Loslösung des Kolbens von der Kolbenhülse sicher vermieden wird.Regardless of the design of the application device with a screw part in the form of a lead cartridge or in the form of a screw part for adjusting an extruded lead, the threaded sleeve preferably has a rear stop for the piston sleeve. Through this rear stop, the retraction movement of the sliding member, i.e. in particular the piston sleeve of the sliding element is defined in a defined manner, so that detachment of the piston from the piston sleeve is reliably avoided.

Die Gewindehülse weist vorzugsweise einen feingängigen Innengewindeabschnitt auf, der sich entlang eines Teiles der axialen Ausdehnung der Gewindehülse und der sich höchstens entlang des halben Umfangs des zentralen Loches der Gewindehülse erstreckt, wobei die Gewindehülse auf der dem Gewindeabschnitt gegenüberliegenden Seite eine Ausnehmung mit dem Gewindeabschnitt entsprechenden Abmessungen aufweist. Die Gewindespindel weist selbstverständlich eine dem feingängigen Innengewindeabschnitt entsprechende Gewindesteigung auf.The threaded sleeve preferably has a fine internal thread section which extends along part of the axial extension of the threaded sleeve and which extends at most along half the circumference of the central hole of the threaded sleeve, the threaded sleeve on the side opposite the threaded section having a recess with dimensions corresponding to the threaded section having. The threaded spindle naturally has a thread pitch corresponding to the smooth internal thread section.

Durch die feingängige Ausbildung der Gewinde ist es möglich, die Mine sehr präzise aus dem Schraubteil herauszubewegen, wobei jede Drehung des Schraubteils nur eine vergleichsweise kleine Vorschub- bzw. Rückzugbewegung der Mine ergibt. Ein derartiger Innengewindeabschnitt kleiner Gewindesteigung ist in der Gewindehülse mittels eines entsprechend geformten Schiebers im Formwerkzeug auf einfache Weise herstellbar. Eine solche Gewindehülse ist in der DE-A- 37 25 792 (veröffentlicht 16.2.89) beschrieben, so dass es sich erübrigt, hier noch einmal detailliert darauf einzugehen.Due to the fine design of the thread, it is possible to move the lead out of the screw part very precisely, each rotation of the screw part resulting in only a comparatively small feed or retraction movement of the lead. Such an internal thread section with a small thread pitch can be produced in the threaded sleeve in a simple manner by means of a correspondingly shaped slide in the molding tool. Such a threaded sleeve is described in DE-A-37 25 792 (published 16.2.89), so that it is not necessary to go into detail here again.

Zwei Ausführungsbeispiele des erfindungsgemässen Auftragsgerätes sind in der Zeichnung dargestellt und werden nachfolgend beschrieben. Es zeigen:

Two exemplary embodiments of the application device according to the invention are shown in the drawing and are described below. Show it:
Figure 1
a section through a first embodiment of the applicator, wherein a front portion, a central portion and a rear portion of the Applicator are shown one above the other, the connection of these sections are indicated schematically by dash-dotted connecting lines, and
Fig. 2
a longitudinal section through a second embodiment of the applicator, in which, as in Figure 1, a front section, a middle section and a rear section of the applicator are shown one above the other, the connection of these three sections being indicated here by a dash-dotted connecting line.

Figur 1 zeigt ein Auftragsgerät 10, bei dem ein Vorderabschnitt, ein mittlerer Abschnitt und ein hinterer Abschnitt des Auftragsgeräts, die miteinander verbunden sind und die miteinander in axialer Richtung fluchten, voneinander getrennt und übereinander dargestellt sind. Das Auftragsgerät 10 weist ein schaftförmiges Griffteil 12 auf, das einseitig offen und auf seiner Hinterseite abgeschlossen ist. Im offenen Endabschnitt des schaftförmigen Griffteiles 12 ist eine Gewindehülse 14 axial unverschiebbar und drehbar gelagert. Zu diesem Zweck weisen das Griffteil 12 und die Gewindehülse 14 ineinander eingreifende Rastansätze 16 und eine Rille 18 auf. Die Gewindehülse 14 weist einen Gewindeabschnitt 20 auf, dem diametral eine Ausnehmung 22 gegenüberliegt. Der Gewindeabschnitt 20 weist eine bestimmte axiale Ausdehnung auf und er erstreckt sich in Umfangsrichtung des zentralen Loches 24 der Gewindehülse 14 höchstens entlang des halben Umfanges des Loches 24. Der Gewindeabschnitt 20 weist eine sehr kleine Gewindesteigung auf, so dass sich ein feingängiges Innengewinde ergibt. Ein Element mit einem solchen Innengewindeabschnitt ist in der Patentanmeldung P 37 25 792.7 detailliert beschrieben, so dass es sich erübrigt, hierauf noch einmal näher einzugehen.FIG. 1 shows an application device 10 in which a front section, a middle section and a rear section of the application device, which are connected to one another, and the aligned with each other in the axial direction, separated from one another and shown one above the other. The application device 10 has a shaft-shaped handle part 12 which is open on one side and closed on its rear side. In the open end portion of the shaft-shaped handle part 12, a threaded sleeve 14 is axially immovable and rotatably mounted. For this purpose, the grip part 12 and the threaded sleeve 14 have interlocking catch projections 16 and a groove 18. The threaded sleeve 14 has a threaded section 20, diametrically opposite a recess 22. The threaded section 20 has a certain axial extent and it extends in the circumferential direction of the central hole 24 of the threaded sleeve 14 at most along half the circumference of the hole 24. The threaded section 20 has a very small thread pitch, so that there is a smooth internal thread. An element with such an internal thread section is described in detail in patent application P 37 25 792.7, so that it is not necessary to go into this in more detail.

Durch das zentrale Loch 24 der Gewindehülse 14 erstreckt sich eine Gewindespindel 26 mit einem Aussengewinde 28 hindurch, wobei das Aussengewinde 28 mit dem Gewindeabschnitt 20 der Gewindehülse 14 in Eingriff ist. Die Gewindespindel 26 weist an ihrem einen Ende einen Kugelkopf 30 und an ihrem vom Kugelkopf 30 abgewandten zweiten Endabschnitt Ansätze 32 und Einsenkungen 34 auf, wobei sich durch die sich in axialer Richtung erstreckenden Einsenkungen 34 hindurch Längsrippen 36 des schaftförmigen Griffteiles 12 hindurcherstrecken. Durch die Längsrippen 36 des Griffteiles 12 und die Einsenkungen 34 bzw. die Ansätze 32 der Gewindespindel 26 wird eine Drehung der Gewindespindel 26 in Bezug zum Griffteil 12 verhindert und gleichzeitig eine axiale Bewegung der Gewindespindel 26 relativ zum schaftförmigen Griffteil 12 ermöglicht. Am vom Kugelkopf 30 abgewandten Ende der Gewindespindel 26 ist an die Gewindespindel 26 einstückig ein Federelement 38 angeformt. Selbstverständlich wäre es auch möglich, das Federelement zwischen dem hinteren Endabschnitt der Gewindespindel 26 und dem hinteren Abschluss 40 des schaftförmigen Griffteils 12 als loses Teil einzufügen. Zur Zentrierung des Federelementes 38 und damit zur Zentrierung der Gewindespindel 26 ist der hintere Abschluss 40 des Griffteils 12 als kegelstumpfförmige Eindellung ausgebildet und das Federelement 38 mit einem ringförmigen Bund 42 versehen.A threaded spindle 26 with an external thread 28 extends through the central hole 24 of the threaded sleeve 14, the external thread 28 being in engagement with the threaded section 20 of the threaded sleeve 14. The threaded spindle 26 has at one end a ball head 30 and at its second end section facing away from the ball head 30 shoulders 32 and depressions 34, longitudinal ribs 36 of the shaft-shaped grip part 12 extending through the depressions 34 extending in the axial direction. The longitudinal ribs 36 of the grip part 12 and the depressions 34 or the lugs 32 of the threaded spindle 26 prevent rotation of the threaded spindle 26 in relation to the grip part 12 and at the same time enable axial movement of the threaded spindle 26 relative to the shaft-shaped grip part 12. On facing away from the ball head 30 A spring element 38 is integrally formed on the threaded spindle 26 at the end of the threaded spindle 26. Of course, it would also be possible to insert the spring element between the rear end section of the threaded spindle 26 and the rear end 40 of the shaft-shaped handle part 12 as a loose part. To center the spring element 38 and thus to center the threaded spindle 26, the rear end 40 of the grip part 12 is designed as a truncated cone indentation and the spring element 38 is provided with an annular collar 42.

Am vorderen Endabschnitt der Gewindespindel 26 ist ein Schiebeorgan 44 befestigt, das einen Kolben 46 und eine Kolbenhülse 48 aufweist. Der Kolben 46 weist einen zentralen Hohlraum 50 auf, in dem Rippen 52 ausgebildet sind. Durch die Rippen 52 und durch einen umlaufenden Bund 54 wird im zentralen Hohlraum 50 ein Aufnahmeraum für den Kugelkopf 30 der Gewindespindel 26 ausgebildet, in den der Kugelkopf 30 federnd einrastbar ist.At the front end portion of the threaded spindle 26, a slide member 44 is attached, which has a piston 46 and a piston sleeve 48. The piston 46 has a central cavity 50 in which ribs 52 are formed. A receiving space for the ball head 30 of the threaded spindle 26 is formed in the central cavity 50 by the ribs 52 and by a circumferential collar 54, in which the ball head 30 can be snapped into place.

Der Kolben 46 und die Kolbenhülse 48 werden in einem dafür vorgesehenen Spritzgiesswerkzeug einstückig hergestellt, wobei die Kolbenhülse 48 und der Kolben 46 in axialer Richtung unmittelbar aneinander anschliessen. Die Kolbenhülse 48 und der Kolben 46 sind mit Sollbruchstellen ausgebildet, entlang welchen der Kolben 46 von der Kolbenhülse 48 getrennt wird, wenn das Schiebeorgan 44 im Auftragsgerät 10 angeordnet wird.The piston 46 and the piston sleeve 48 are produced in one piece in an injection molding tool provided for this purpose, the piston sleeve 48 and the piston 46 directly adjoining one another in the axial direction. The piston sleeve 48 and the piston 46 are formed with predetermined breaking points along which the piston 46 is separated from the piston sleeve 48 when the sliding member 44 is arranged in the applicator 10.

Die Gewindehülse 14 weist Ausnehmungen 56 auf, in welche ein Schraubteil 58 mit Erhebungen 60 derart einrastet,dass die Gewindehülse 14 mit dem Schraubteil 58 fest verbunden ist. Eine Drehung des Schraubteiles 58 um die zentrale Mittellinie 62 herum ergibt eine Drehung der Gewindehülse 14. Da die Gewindespindel 26 an einer Drehung relativ zum Griffteil 12 gehindert ist, führt eine Drehung der axial unverschiebbaren Gewindehülse 14 zu einer axialen Verschiebung der Gewindespindel 26 und damit zur einer axialen Verschiebung des Kolbens 46 des Schiebeorgans 44. Die Kolbenhülse 48 ist an einer Mitbewegung mit dem Kolben 46 gehindert, weil die Kolbenhülse 48 in einer mit einem Anschlag 64 ausgebildeten Ausnehmung 66 anliegt. Die im Schraubteil 58 befindliche Mine 68, die insbesondere aus einer streichfähigen Masse besteht, wird durch eine Drehung des Schraubteils 58 mittels des Kolbens 46 des Schiebeorgans 44 aus der vorderen Öffnung 70 des Schraubteils 58 herausbewegt.The threaded sleeve 14 has recesses 56 into which a screw part 58 with elevations 60 snaps in such a way that the threaded sleeve 14 is firmly connected to the screw part 58. A rotation of the screw part 58 around the central center line 62 results in a rotation of the threaded sleeve 14. Since the threaded spindle 26 is prevented from rotating relative to the handle part 12, a rotation of the axially immovable leads Threaded sleeve 14 for an axial displacement of the threaded spindle 26 and thus for an axial displacement of the piston 46 of the sliding member 44. The piston sleeve 48 is prevented from moving with the piston 46 because the piston sleeve 48 rests in a recess 66 formed with a stop 64. The lead 68 located in the screw part 58, which in particular consists of a spreadable mass, is moved out of the front opening 70 of the screw part 58 by rotating the screw part 58 by means of the piston 46 of the sliding element 44.

Bei der in Figur 1 dargestellten Ausbildung des Auftragsgeräts 10 ist das Schraubteil 58 vorzugsweise als Minenpatrone ausgebildet, in die die Mine 68 eingegossen ist.In the embodiment of the application device 10 shown in FIG. 1, the screw part 58 is preferably designed as a refill cartridge into which the refill 68 is cast.

Sobald die Mine 68 verbraucht ist, wird das Schraubteil 58 in Gestalt der verbrauchten Minenpatrone vom Griffteil 12 entfernt und durch eine neue Minenpatrone mit einer eingegossenen Mine 68 ersetzt. Dieser Austausch einer verbrauchten Minenpatrone 58 durch eine neue Minenpatrone erfolgt selbstverständlich erst dann, wenn das Schiebeorgan 44 in die in Figur 1 dargestellte zurückgezogene Position zurückgestellt ist.As soon as the lead 68 is used up, the screw part 58 in the form of the used lead cartridge is removed from the handle part 12 and replaced by a new lead cartridge with a cast lead 68. This exchange of a used refill cartridge 58 by a new refill cartridge, of course, only takes place when the slide member 44 is returned to the retracted position shown in FIG.

Mit der Bezugsziffer 72 ist eine Verschlusskappe bezeichnet, mit welcher das Auftragsgerät 10 verschliessbar ist, um die Mine 68 zu schützen.The reference numeral 72 denotes a closure cap with which the applicator 10 can be closed in order to protect the lead 68.

Figur 2 zeigt eine zweite Ausführungsform des Auftragsgerätes 10 mit einem Griffteil 12, einer im Griffteil 12 drehbar und axial unverschiebbar gelagerten Gewindehülse 14, einer im Griffteil 12 in Bezug zum Griffteil 12 nicht drehbaren aber axial verschiebbaren Gewindespindel 26, einem am Vorderende der Gewindespindel 26 vorgesehenen Schiebeorgan 44, einem Schraubteil 58, einer Mine 68 und einer Verschlusskappe 72. Diese Ausbildung des Auftragsgerätes 10 unterscheidet sich von der in Figur 1 dargestellten Ausführungsform insbesondere dadurch, dass das Schiebeorgan 44 aus einem Kolben 46 und einer Kolbenhülse 48 besteht, die in der dargestellten Weise miteinander fest verbunden sind. Eine Drehung des Schraubteiles 58 relativ gegen das schaftförmige Griffteil 12 ergibt eine Drehung der im Griffteil 12 axial unverschiebbaren Gewindehülse 14,so dass die im Griffteil 12 axial bewegliche und gegen das Griffteil undrehbare Gewindespindel 26 in die Gewindehülse 14 eingeschraubt und bei entsprechender Drehung desSchraubteiles 58 durch die Gewindehülse 14 durchgeschraubt wird. Gleichzeitig mit dieser Vorschubbewegung der Gewindespindel 26 führt das Schiebeorgan 44 eine entsprechende Vorschubbewegung aus, so dass die in der Kolbenhülse 48 festgelegte Mine 68 eine entsprechende Vorschubbewegung ausführt. Da die Gewindespindel 26 und der Gewindeabschnitt 20 der Gewindehülse 14 ein feingängiges Gewinde aufweisen, ergibt eine Drehung des Schraubteiles 58 eine sehr feinfühlige Vorschubbewegung der Mine 68, bei der es sich um eine extrudierte Mine handelt. In Figur 2 ist der Gewindeabschnitt mit dem Aussengewinde 28 vom Gewindeabschnitt 20 der Gewindehülse 14 entfernt dargestellt; infolge des zwischen dem hinteren Abschluss 40 des Griffteiles 12 und den Ansätzen 32 der Gewindespindel 26 vorgesehenen Federelementes 38 wird die Gewindespindel 26 stets mit einer derartigen Kraft gegen den Gewindeabschnitt 20 der Gewindehülse 14 gedrückt, dass sich ein Eingriff zwischen dem Aussengewinde der Gewindespindel 26 und dem Innengewinde der Gewindehülse 14 ergibt.Figure 2 shows a second embodiment of the applicator 10 with a handle part 12, a threaded sleeve 14 rotatably and axially non-displaceably mounted in the handle part 12, a threaded spindle 26 which is non-rotatable but axially displaceable in the handle part 12 with respect to the handle part 12, and one provided at the front end of the threaded spindle 26 Sliding member 44, a screw 58, a lead 68 and a closure cap 72. This design of the application device 10 differs from the embodiment shown in FIG. 1 in particular in that the sliding member 44 consists of a piston 46 and a piston sleeve 48 which are firmly connected to one another in the manner shown. A rotation of the screw part 58 relative to the shaft-shaped handle part 12 results in a rotation of the threaded sleeve 14 which is axially immovable in the handle part 12, so that the threaded spindle 26, which is axially movable in the handle part 12 and non-rotatable against the handle part, is screwed into the threaded sleeve 14 and with a corresponding rotation of the screw part 58 the threaded sleeve 14 is screwed through. Simultaneously with this feed movement of the threaded spindle 26, the sliding member 44 executes a corresponding feed movement, so that the lead 68 fixed in the piston sleeve 48 executes a corresponding feed movement. Since the threaded spindle 26 and the threaded section 20 of the threaded sleeve 14 have a fine thread, rotation of the screw part 58 results in a very sensitive feed movement of the lead 68, which is an extruded lead. FIG. 2 shows the threaded section with the external thread 28 removed from the threaded section 20 of the threaded sleeve 14; As a result of the spring element 38 provided between the rear end 40 of the grip part 12 and the lugs 32 of the threaded spindle 26, the threaded spindle 26 is always pressed against the threaded portion 20 of the threaded sleeve 14 with such a force that an engagement between the external thread of the threaded spindle 26 and the Internal thread of the threaded sleeve 14 results.

Das Schraubteil 58 ist mit einem zentralen Hohlraum 74 ausgebildet, der an seinem Vorderende durch einen Anschlag 76 begrenzt ist. Der Anschlag 76 begrenzt die Vorschubbewegung der Kolbenhülse 48 des Schiebeorgans 44, während bei einer entsprechenden Drehung des Schraubteiles 58 der Kolben 46 noch eine bestimmte Strecke vorwärts bewegt werden kann. Dadurch ergibt sich eine Auswurfbetätigung für den in der Kolbenhülse 48 vorhandenen Endabschnitt der Mine 68, so dass die Mine 68 vollständig aus dem Auftragsgerät 10 ausgeworfen werden kann, ohne dass die Mine 68 berührt werden muss. Sobald der Minenrest aus dem Auftragsgerät 10 ausgeworfen ist, wird durch entsprechende Drehbetätigung des Schraubteiles 58 das Schiebeorgan 44 in die zurückgezogene Ausgangsposition zurückgestellt und im zentralen Hohlraum 74 des Schraubteiles 58 eine neue extrudierte Mine 68 angeordnet. Bei dieser Ausbildung des Auftragsgerätes 10 ist das Schiebeorgan 44 im zentralen Hohlraum 74 gegen Verdrehungen gesichert angeordnet, so dass bei einer Betätigung des Schraubteiles 58 nur eine axiale Bewegung der Mine 68 aus dem Schraubteil 58 heraus bzw. in das Schraubteil 58 hinein erfolgt, ohne dass sich die Mine 68 dreht.The screw part 58 is formed with a central cavity 74 which is delimited by a stop 76 at its front end. The stop 76 limits the feed movement of the piston sleeve 48 of the sliding member 44, while at one corresponding rotation of the screw member 58 of the piston 46 can still be moved forward a certain distance. This results in an ejection actuation for the end section of the lead 68 present in the piston sleeve 48, so that the lead 68 can be completely ejected from the application device 10 without the lead 68 having to be touched. As soon as the rest of the lead is ejected from the applicator 10, the slide member 44 is returned to the retracted starting position by correspondingly actuating the screw part 58 and a new extruded lead 68 is arranged in the central cavity 74 of the screw part 58. In this embodiment of the applicator 10, the sliding member 44 is arranged in the central cavity 74 to be secured against rotation, so that when the screw part 58 is actuated, only an axial movement of the lead 68 out of the screw part 58 or into the screw part 58 takes place without Mine 68 is spinning.

Mit der Bezugsziffer 78 ist ein hinterer Anschlag bezeichnet, der an der Gewindehülse 14 vorgesehen ist und der zur Begrenzung der Rückzugbewegung des Schiebeorgans 44 bzw. insbesondere deren Kolbenhülse 48 dient.Reference numeral 78 denotes a rear stop, which is provided on the threaded sleeve 14 and which serves to limit the retraction movement of the sliding member 44 or, in particular, its piston sleeve 48.

In den Figuren 1 und 2 sind gleiche Einzelteile mit denselben Bezugsziffern bezeichnet, so dass es sich erübrigt, in Verbindung mit Figur 2 alle diese Einzelteile noch einmal detailliert zu beschreiben.In FIGS. 1 and 2, the same individual parts are designated with the same reference numerals, so that it is not necessary to describe all these individual parts again in detail in connection with FIG.
