Abstract

PCT No. PCT/EP96/01701 Sec. 371 Date Oct. 2, 1997 Sec. 102(e) Date Oct. 2, 1997 PCT Filed Apr. 24, 1996 PCT Pub. No. WO96/35344 PCT Pub. Date Nov. 14, 1996The object of a snap fastener closure is to couple a male part with a female part (20) as easily as possible, but so that it is difficult to uncouple them. The female part (20) comprises a push plate (30) which is movable longitudinally in a housing (23) and forks into two plate legs in the interior of the housing. The two plate legs are formed of two portions (31, 32) which are profiled differently with respect to the closing head (12) of the male part, one of these portions (31) serving to lock and the other portion (32) serving to release the closing head (12). In order to achieve easy coupling, it is proposed that the portion (31) acting to lock is provided at the free ends of the two plate legs so that they can spread apart elastically. Then, by inserting the closing head (12) of the male part, an automatic coupling in is made possible between the two plate legs. This portion (31) thus becomes the coupling portion. One plate leg is provided with a bent lengthening (36) which acts as a spring on the push plate (30) and, by its coupling portion (31), holds the push plate (30) in alignment with an entrance hole for the closing head (12) in the housing (23).

Description

Die Erfindung richtet sich auf einen Druckknopfverschluß der im Oberbegriff von Anspruch 1 angegebenen Art. Ein solcher Druckknopfverschluß besitzt einen mehrteiligen Matrizenteil mit einem ein Einsteckloch aufweisenden Gehäuse für den Patrizenteil. In diesem Gehäuse ist eine aus elastischem Material bestehende Schiebeplatte angeordnet, die gegabelt ist und mit ihren beiden Plattenschenkeln in einem gemeinsamen Kanal des Gehäuses geführt wird. Die Plattenschenkel sind in Abschnitte mit zueinander unterschiedlicher Weite gegliedert und besitzen einen Verriegelungsabschnitt, wo die Plattenschenkel kleiner als ein Schließkopf des Patrizenteils ausgebildet ist. Dies kennzeichnet den Verriegelungsabschnitt der Schiebeplatte. Dieser Verriegelungsabschnitt läßt aber auch eine elastische Spreizbewegung zu und ist daher auch ein Kupplungsabschnitt, um den Schließkopf des Patrizenteils durch das Einsteckloch ins Gehäuse einführen zu können. Die Schiebeplatte steht unter der Wirkung einer Feder und läßt sich soweit einschieben, bis ein großer Abstand zwischen den Plattenschenkeln an das Einsteckloch gelangt und ein axiales Herausziehen des Patrizenteils ermöglicht.The invention is directed to a snap closure in the preamble Art specified by claim 1. Such a snap fastener has a multi-part die part with an insertion hole Housing for the male part. In this case one is off elastic material existing sliding plate arranged, the forked and with their two plate legs in a common channel the housing is guided. The plate legs are in sections with divided into different widths and have a locking section, where the plate legs are smaller than a closing head of the Male part is formed. This marks the locking section the sliding plate. This locking section also leaves one elastic spreading movement and is therefore also a coupling section, around the locking head of the male part through the insertion hole in the housing to be able to introduce. The sliding plate is under the effect of a Spring and can be inserted until a large distance between the plate legs reach the insertion hole and pull them out axially of the male part.

Bei dem bekannten Druckknopfverschluß dieser Art (CH 442 833 A) haben die beiden Plattenschenkel die gleiche Länge und stützen sich mit ihren Schenkelenden an den beiden Seiten eines winkelförmigen Vorsprungs im Gehäuse ab. Beim Eindrücken der Schiebeplatte ins Gehäuse gleiten die beiden Schenkelenden an den zueinander spiegelbildlich geneigten Seiten des Winkels und spreizen die beiden Plattenschenkel im Verriegelungsabschnitt soweit auseinander, bis der von ihnen hintergriffene Schließkopf des eingekuppelten Patrizenteils aus dem Gehäuse des Matrizenteils herausgezogen werden kann. Die beiden Plattenschenkel sind im Übergang zum gemeinsamen Betätigungsende durch einen kreisförmigen Bogen verbunden, der die Baubreite der Schiebeplatte erhöht und die Spreizelastizität der Schenkelenden verbessert. Dieser verbreiterte Übergang begrenzt den Ausschub der Schiebeplatte und erfordert einen entsprechend erweiterten Kanal im Gehäuse.In the known snap fastener of this type (CH 442 833 A) the two plate legs are the same length and support each other their thigh ends on both sides of an angular projection in the housing. Slide into the housing when pushing in the sliding plate the two ends of the legs on the mirror image inclined to each other Sides of the angle and spread the two plate legs in the locking section so far apart, until the closing head they attacked of the coupled male part from the housing of the female part can be pulled out. The two plate legs are in transition connected to the common actuation end by a circular arc, which increases the width of the sliding plate and the spreading elasticity the leg ends improved. This broadened transition limits the extension of the sliding plate and requires a correspondingly expanded Channel in the housing.

Wegen der ungleichförmigen Baubreite der Schiebeplatte benötigt man ein mehrteiliges Gehäuse. Deshalb ist zur Herstellung des Matrizenteils eine teuere Einzelherstellung von zwei Gehäuseteilen und eine umständliche, zeitaufwendige Montage erforderlich. Zwar ist der Abstand zwischen den beiden Plattenschenkeln im bogenförmigen Übergang erweitert, doch kann dieser Bereich zum Entkuppeln des Patrizenteils nicht genutzt werden, weil beim Eindrücken die Schiebeplatte nur so wenig axialbewegt wird, daß der Patrizenteil noch im kupplungswirksamen Verriegelungsabschnitt verbleibt. Bei diesem Druckknopfverschluß wird für das Entkuppeln des Patrizenteils die gleiche Spreizelastizität zwischen den beiden Plattenschenkeln genutzt, die, zusammen mit dem winkelförmigen Vorsprung, die Ausschubkraft erzeugt. Dadurch stehen die Plattenschenkel unter einer ständigen, im Ausspreizsinne wirkenden Kraft, die im Laufe der Zeit zu einer Werkstoffermüdung führen kann. Wenn aber die Elastizität erlahmt, ist die Eingriffssicherheit des Patrizenteils im Matrizenteil gefährdet.Because of the non-uniform width of the sliding plate you need a multi-part housing. This is why the die part is made an expensive individual production of two housing parts and a cumbersome, time-consuming assembly required. Although the distance between the two plate legs extended in the arched transition, but this area cannot be used to decouple the male part, because when pushed in, the sliding plate moves only so little axially is that the male part is still in the coupling-effective locking section remains. This snap fastener is used for uncoupling of the male part the same spreading elasticity between the two plate legs used, which, together with the angular projection, the extension force is generated. As a result, the plate legs are below a constant, expansive force that Time can lead to material fatigue. But if the elasticity paralyzed, the security of the male part in the female part at risk.

Der Erfindung liegt die Aufgabe zugrunde, einen Druckknopfverschluß der im Oberbegriff des Anspruches 1 genannten Art zu entwickeln, der sich preiswerter herstellen läßt und sich durch eine zuverlässige Verriegelung auszeichnet. Dies wird erfindungsgemäß durch die im Kennzeichen des Anspruches 1 angeführten Maßnahmen erreicht, denen folgende besondere Bedeutung zukommt.The invention has for its object a snap fastener to develop the type mentioned in the preamble of claim 1, which can be manufactured more cheaply and is reliable Locking distinguished. This is according to the invention by the in the license plate of the measures set out in claim 1, the following is of particular importance.

Bei der Erfindung ist der eine Plattenschenkel verlängert und in sich gekröpft. Diese Plattenverlängerung bildet die längselastische Feder, die für eine Ausschubkraft der Schiebeplatte sorgt. Beim Eindrücken des Schiebers wird folglich der Abstand zwischen den beiden Plattenschenkeln nicht verändert, sondern nur der verlängerte Plattenschenkel deformiert. Die Kanalwände im Gehäuse des Matrizenteils können die Schiebeplatte führen und bedürfen keiner seitlichen Aufweitung, wie im Stand der Technik. Daher ist es möglich, den Gehäusekanal einfach parallelwandig auszubilden, weil dann das ganze Gehäuse einstückig aus gießfähigem oder preßbarem Material, wie Kunststoff, ausgebildet werden kann. Ein mehrteiliges Gehäuse, wie im Stand der Technik, wird eingespart, was eine teuere Einzelherstellung und umständliche Montage mehrerer Gehäuseteile erspart. Der Matrizenteil des erfindungsgemäßen Druckknopfverschlusses besteht also nur aus zwei Teilen, nämlich einem einstückigen Gehäuse und einer zweischenkeligen Schiebeplatte.In the invention, the one plate leg is extended and in itself cranked. This plate extension forms the longitudinally elastic spring, which ensures an extension force of the sliding plate. When pushing in the slide is the distance between the two plate legs not changed, only the elongated plate leg deformed. The channel walls in the housing of the die part can be the sliding plate lead and do not require any lateral expansion, as in the stand of the technique. It is therefore possible to simply have the housing channel parallel-walled form, because then the whole housing is made of pourable or pressable material, such as plastic, can be formed. On multi-part housing, as in the prior art, is saved what an expensive individual production and cumbersome assembly of several housing parts saved. The die part of the snap fastener according to the invention consists of only two parts, namely a one-piece housing and a two-legged sliding plate.

Ausweislich der Fig. 4 und 5 besteht der Druckknopfverschluß nach der Erfindung aus einem Matrizenteil 20, welches an einem ersten Träger 50 befestigt ist, und einem Patrizenteil 10, der an einem zweiten Träger 40 sitzt. Die beiden Druckknopfteile 10, 20 dienen dazu, wahlweise die beiden Träger 40, 50 aneinander festzuhalten oder voneinander zu lösen. Dazu besitzen die beiden Druckknopfteile 10, 20 zueinander komplementäre patrizenförmige bzw. matrizenförmige Kuppelflächen 11, 21.As shown in FIGS. 4 and 5, the snap fastener is after of the invention from a die part 20, which on a first carrier 50 is attached, and a male part 10, which is attached to a second support 40 sits. The two push button parts 10, 20 serve to choose to hold the two carriers 40, 50 together or from each other to solve. For this purpose, the two push button parts 10, 20 have each other complementary male or female domed surfaces 11, 21.

Die Kuppelflächen 11 vom Patrizenteil 10 sind, ausweislich der Fig. 5, in einen Schließkopf 12 und einen demgegenüber querschnittsmäßig abgesetzten Schließhals 13 gegliedert. Die Kuppelflächen 11 sitzen über einen Schaft 15 im vorliegenden Fall an einem Endflansch 16, der zur Befestigung des Patrizenteils 10 an seinem Träger 40 dient. Im dargestellten Ausführungsbeispiel erfolgt die Befestigung über eine Schweißverbindung 17 der Flanschunterseite mit der Oberseite 41 des Trägers 40. Es können natürlich auch beliebig andere Befestigungsmaßnahmen zur Anbringung des Patrizenteils 10 am Träger 40 herangezogen werden, z. B. Niete, die von der Unterseite 42 des Trägers 40 aus gesetzt werden und z. B. am Flansch 16 angreifen. Ebenso können Kerb-Nägel eingesetzt werden, die im Inneren des Patrizenteils, z. B. im Bereich einer im Schaft 15 vorgesehenen Axialbohrung, verankert sind.The dome surfaces 11 of the male part 10 are, as shown in FIG. 5, in a closing head 12 and a cross-section in contrast offset locking neck 13 structured. The dome surfaces 11 sit over a shaft 15 in the present case on an end flange 16 which for Attachment of the male part 10 on its carrier 40 is used. In the illustrated The embodiment is carried out via a welded connection 17 of the flange underside with the top 41 of the carrier 40. Of course, any other fastening measures can also be used Attachment of the male part 10 to the carrier 40 can be used, e.g. B. rivets, which are placed from the underside 42 of the carrier 40 and Z. B. attack on flange 16. Notch nails can also be used be inside the male part, for. B. in the area of provided in the shaft 15 axial bore are anchored.

Der Matrizenteil 20 besteht, wie aus den Einzelteil-Zeichnungen in Fig. 1a bis 2b zu ersehen ist, aus zwei Bestandteilen 23, 30, nämlich einem Gehäuse 23 einerseits und einem darin längsbeweglichen Schieber 30 andererseits. Das Gehäuse 23 könnte zwar aus zwei aneinander montierbaren Gehäusehälften zusammengesetzt sein, jedoch ist es vorteilhafter, wie das Ausführungsbeispiel in Fig. 1a und 1b zeigt, das Gehäuse 23 einstückig auszubilden. Das Gehäuse 23 wird an der Schauseite 51 des Trägers befestigt, wofür im vorliegenden Fall ein zusätzlicher Bauteil, nämlich der in Fig. 3a und 3b gezeigte Gegenhalter 43 dient, der nach Art einer Mutter gestaltet ist. Es versteht sich, daß zur Anbringung des Matrizenteils 20 am Träger 50 jede andere, an sich bekannte Befestigungsmethode herangezogen werden könnte.The die part 20 consists, as from the individual part drawings in Fig. 1a to 2b can be seen from two components 23, 30, namely one Housing 23 on the one hand and a slide 30 which is longitudinally movable therein on the other hand. The housing 23 could indeed consist of two assemblies that can be assembled together Halves of the housing can be composed, but it is more advantageous As the exemplary embodiment in FIGS. 1 a and 1 b shows, the housing 23 train in one piece. The housing 23 is on the front side 51 of the Carrier attached, for which an additional component in the present case, namely, the counter-holder 43 shown in FIGS. 3a and 3b, which after Kind of a mother. It is understood that for attachment of the die part 20 on the carrier 50 any other known fastening method could be used.

Das Gehäuse 23 besitzt zunächst ein Einsteckloch 24 in Form einer axialen Bohrung, in welche zum Kuppeln die patrizenförmigen Kuppelflächen 11 vom Patrizenteil 10 im Sinne des aus Fig. 4 entnehmbaren Einsteckpfeils 18 eingeführt werden. Dieses Einsteckloch 24 durchquert ein im Gehäuseinneren eingelassener Kanal 25, der zur Führung des Schiebers 30 dient. Der Führungskanal 25 mündet mit einem Schlitz 26 an einer den Gehäuseumfang bestimmenden Seitenfläche 27 des Gehäuses. Nach seiner Montage ragt aus diesem Schlitz, wie aus Fig. 4 hervorgeht, der Schieber 30 mit einem Endstück 37 heraus, an dem sich eine verbreiterte Handhabe 38 befindet. Die Montage der beiden Bauteile 23, 30 wird in folgender Weise vollzogen.The housing 23 initially has an insertion hole 24 in the form of a axial bore, in which the male-shaped dome surfaces for coupling 11 of the male part 10 in the sense of the insertable arrow shown in FIG. 4 18 are introduced. Crosses this insertion hole 24 a channel 25 embedded in the housing, which for guiding the slide 30 serves. The guide channel 25 opens out with a slot 26 a side surface 27 of the housing which determines the circumference of the housing. After assembly, this slot protrudes, as can be seen in FIG. 4, the slider 30 with an end piece 37, on which a widened Handle 38 is located. The assembly of the two components 23, 30 is carried out in the following way.

Ausweislich der Fig. 2a, 2b ist der Schieber 30 plattenförmig gestaltet, jedoch erhebt sich ein Vorsprung 39 und, der besseren Griffigkeit wegen, auch die Handhabe 38 einseitig aus der Plattenebene heraus. Diesem Vorsprung 39 ist an einer Innenfläche des Führungskanals 25 eine Kulisse 29 zugeordnet, die, nach der Montage der Schiebeplatte 30, zu deren Führung dient. Die Montage erfolgt einfach dadurch, daß die Schiebeplatte 30 mit seinem noch näher zu beschreibenden, vor dem Endstück 37 liegenden Plattenabschnitt durch den seitlichen Schlitz 26 im Sinne des in Fig. 2a erkennbaren Montagepfeils 19 eingeführt wird. Weil im vorliegenden Fall die Schiebeplatte 30 aus formelastischem Material, wie Kunststoff, besteht, wirken der Vorsprung 39 und die Kulisse 29 wie eine Schnappverbindung zusammen. Der Vorsprung 39 besitzt nämlich eine aus Fig. 2a ersichtliche Auflaufschräge 49, die durch elastische Deformation des Vorsprungs 39 selbst und/oder der Gehäusewand durch den Schlitz 26 hindurch schnappt und in die Kulisse 29 einrastet. Für eine fallweise gewünschte Demontage der Schiebeplatte 30 aus dem Gehäuse 23 kann sein Vorsprung 39 eine zur Auflaufschräge 49 gegenüberliegende, aus Fig. 2a ersichtliche Neigungsfläche aufweisen, die ein zur Montagebewegung 19 gegensinniges Herausziehen der Schiebeplatte 30 aus dem Kanal 25 zuläßt.As shown in FIGS. 2a, 2b, the slide 30 is plate-shaped, however, there is a projection 39 and, for better grip, also the handle 38 on one side out of the plate level. This Projection 39 is a backdrop on an inner surface of the guide channel 25 29 assigned to the, after the assembly of the sliding plate 30 Leadership serves. The assembly is done simply by the sliding plate 30 with his to be described in more detail, lying in front of the end piece 37 Plate section through the side slot 26 in the sense of in 2a recognizable assembly arrow 19 is inserted. Because in the present If the sliding plate 30 is made of a flexible material, such as plastic, there is, the projection 39 and the backdrop 29 act like one Snap connection together. The projection 39 has one 2a apparent run-up slope 49, caused by elastic deformation of the projection 39 itself and / or the housing wall through the slot 26 snaps through and snaps into the scenery 29. For a case by case Desired disassembly of the sliding plate 30 from the housing 23 can its projection 39 is opposite to the ramp 49 Fig. 2a have visible inclination surface, which for a mounting movement 19 pulling the sliding plate 30 in opposite directions out of the channel 25 permits.

Wie aus Fig. 2b zu entnehmen ist, ist die Schiebeplatte 30 zu ihrem Ende hin in zwei Plattenschenkel 34, 35 gegabelt. Diese Plattenschenkel 34, 35 sind an ihren einander zugekehrten Kanten mit einem bestimmten Profil versehen, welches sie in zwei Abschnitte 31, 32 gliedert. Nach ihrer Montage, die am besten aus Fig. 6a zu ersehen ist, steht die Schiebeplatte 30 unter der Wirkung einer Feder 36, die bestrebt ist, sie in der dort gezeigten Ausgangsstellung zu halten, die aus noch näher zu erläuternden Gründen nachfolgend kurz "Kupplungsstellung" bezeichnet werden soll. Die Feder 36 bewirkt nämlich eine durch den Kraftpfeil 46 von Fig. 4 und 6a ersichtliche Federkraft. Dabei stößt der Vorsprung 39 von der Schiebeplatte 30 an das äußere Ende seiner Kulissenführung 29, die dabei als Endanschlag fungiert.As can be seen from Fig. 2b, the sliding plate 30 is theirs End forked into two plate legs 34, 35. These plate legs 34, 35 are at their mutually facing edges with a certain Provide profile, which divides it into two sections 31, 32. To the slide plate stands when it is assembled, which can best be seen from FIG. 6a 30 under the action of a spring 36 which strives to them to keep in the starting position shown there, which from even closer for explanatory reasons hereinafter referred to as "clutch position" shall be. The spring 36 namely causes one by the force arrow 46 of FIGS. 4 and 6a apparent spring force. The head start here 39 from the sliding plate 30 to the outer end of its link guide 29, which acts as an end stop.

Die dem Patrizenteil 10 zugeordneten matrizenförmigen Kuppelflächen 21 vom Matrizenteil 20 sind in dem Abschnitt 31 der Schiebeplatte 30 angeordnet, der daher nachfolgend kurz "Kupplungsabschnitt" bezeichnet werden soll. Dieser Kupplungsabschnitt 31 besitzt die eigentliche matrizenförmige Schließöffnung 22, die von den profilierten Innenkanten 21 der beiden Plattenschenkel 34, 35 erzeugt wird. Zwischen den beiden Schenkelkanten 21 liegt eine kleine lichte Weite 65 gemäß Fig. 2b vor. Der eine Plattenschenkel 35 ist verlängert und diese Verlängerung bildet zugleich die vorbeschriebene Feder 36. Die Feder 36 ist also mit dem Schieber 30 einstückig ausgebildet und nutzt die elastischen Eigenschaften des zu seiner Herstellung herangezogenen Materials, wie eines Kunststoffs. Die Feder 36 besteht aus einer in der Plattenebene liegenden V-förmigen Verkröpfung. Im Montagefall, gemäß Fig. 6a, stützt sich das freie Ende dieser V-Feder 36 an der am einfachsten vom Kanalboden selbst gebildeten Innenfläche 28 ab.The matrix-shaped dome surfaces assigned to the male part 10 21 of the die part 20 are in the section 31 of the sliding plate 30 arranged, which therefore hereinafter referred to briefly "coupling section" shall be. This coupling section 31 has the actual matrix shape Closing opening 22 by the profiled inner edges 21 of the two plate legs 34, 35 is generated. Between the two Leg edges 21 have a small clear width 65 according to FIG. 2b. One plate leg 35 is extended and this extension forms at the same time the spring 36 described above. The spring 36 is thus with the Slider 30 formed in one piece and uses the elastic properties of the material used to manufacture it, such as a plastic. The spring 36 consists of a V-shaped lying in the plane of the plate Cranking. In the case of assembly, as shown in FIG. 6a, the free end is supported this V-spring 36 on the easiest formed by the channel floor itself Inner surface 28 from.

In der Kupplungsstellung des Schiebers 30, gemäß Fig. 4 und Fig. 6a, sind die vom Schieber 30 erzeugten matrizenförmigen Kuppelflächen 21, welche die vorgenannte kleine lichte Weite 65 zwischen sich schließen, in axialer Ausrichtung mit dem Einsteckloch 24 des Gehäuses 23. Beim Einstecken des Patrizenteils 10 im Sinne des bereits erwähnten, aus Fig. 4 ersichtlichen Einsteckpfeils 18, stoßen die am freien Ende vorgesehenen Neigungsflächen 53 vom in Fig. 5 gezeigten Schließkopf 12 gegen die matrizenförmigen Kuppelflächen 21 und spreizen die sie bildenden beiden Plattenschenkel 34, 35 federelastisch auseinander. Dadurch kann der ganze, gegenüber der lichten Weite der Schließöffnung 22 verbreitete Schließkopf 12 hindurchgelangen. Die Übergangsstelle zwischen dem Schließkopf 12 und dem angrenzenden Schließhals 13 im Patrizenteil 10 ist, wie aus Fig. 5 hervorgeht, mit einem scharfen Hinterschnitt 14 versehen. Wenn die aus Fig. 4 ersichtliche, strichpunktiert angedeutete Kupplungslage des Patrizenteils 10 erreicht ist, schnappt die aus Fig. 2b ersichtliche Schließöffnung 22 um den strichpunktiert in Fig. 4 angedeuteten Schließhals 13 des Patrizenteils 10, wodurch der Hinterschnitt 14 die Plattenoberseite der Schiebeplatte 30 übergreift. Die beiden Plattenschenkel 34, 35 umgreifen zangenartig den Schließhals 13. Der Schließkopf 12 besitzt einen aus Fig. 5 erkennbaren Außendurchmesser 54, der größer als die lichte Weite der Schließöffnung 22 bei ungespreizten Plattenschenkeln 34, 35 im Schieber 30 ausgebildet ist. In Kupplungsstellung der Schiebeplatte 30 läßt sich folglich der Patrizenteil 10 nicht gegensinnig zu dem erwähnten Einsteckpfeil 18 im Sinne des in Fig. 4 ebenfalls angedeuteten Pfeils 48 entkuppeln. Dazu muß vorher die Schiebeplatte 30 in ihre aus Fig. 6b ersichtliche Stellung überführt werden, die aus folgenden Gründen kurz "Entkupplungsstellung" bezeichnet werden soll.In the coupling position of the slide 30, according to FIGS. 4 and 6a, are the matrix-shaped dome surfaces generated by the slide 30 21, which close the aforementioned small clear width 65 between them, in axial alignment with the insertion hole 24 of the housing 23. When Insert the male part 10 in the sense of that already mentioned Fig. 4 visible insertion arrow 18 encounter the provided at the free end Inclination surfaces 53 from the closing head 12 shown in FIG the matrix-shaped dome surfaces 21 and spread out those that form them two plate legs 34, 35 apart resiliently. This can the whole, compared to the clear width of the closing opening 22 Closing head 12 get through. The transition point between the Closing head 12 and the adjacent closing neck 13 in the male part 10 is, as is apparent from Fig. 5, with a sharp undercut 14 provided. If the one shown in FIG. 4, indicated by dash-dotted lines Coupling position of the male part 10 is reached, the snaps from Fig. 2b visible closing opening 22 around the one indicated by dash-dotted lines in FIG. 4 Closing neck 13 of the male part 10, which causes the undercut 14 engages over the top of the sliding plate 30. The two plate legs 34, 35 grip around the closing neck 13 like pliers. The closing head 12 has an outer diameter 54 recognizable from FIG. 5, which is larger than the clear width of the closing opening 22 in the case of non-spread Plate legs 34, 35 is formed in the slider 30. In clutch position the sliding plate 30, consequently, the male part 10 cannot be in the opposite direction to the insertion arrow 18 mentioned in the sense of the in FIG. 4 Disengage arrow 48, also indicated. To do this, the Sliding plate 30 are transferred into their position shown in FIG. 6b, which is briefly called "decoupling position" for the following reasons shall be.

Für die Entkupplungsstellung von Fig. 6b wird die Schiebeplatte 30 mittels einer Handhabe 38 im Sinne des Bewegungspfeils 56 ins Gehäuse 23 eingedrückt, und zwar gegen die Wirkung der bereits erwähnten Federkraft 46. Dadurch wird die Feder 36 entsprechend deformiert. Der erwähnte, an der Schiebeplatte 30 sitzende Vorsprung 39 kommt ans innere Ende seiner gehäuseseitigen Kulisse 29 zu liegen. In dieser Entkupplungsstellung ist der Schieber 30 mit dem benachbarten, in Fig. 2b erkennbaren Abschnitt 32 in axialer Ausrichtung mit dem gehäuseseitigen Einsteckloch 24. In diesem Abschnitt 32 befindet sich eine Freigabeöffnung 33, deren lichte Öffnungsweite 55 größer, mindestens aber gleich dem vorerwähnten, aus Fig. 5 erkennbaren Querschnitt 54 vom Schließkopf 12 des Patrizenteils 10 ausgebildet ist. Dieser Abschnitt 32 soll daher als "Freigabeabschnitt" bezeichnet werden. Diese erweiterte Freigabeöffnung 33 wird durch eine entsprechend erweiterte Profilierung der beiden vorbeschriebenen Plattenschenkel 34, 35 gebildet. Zwischen der dortigen Schließöffnung 22 und der diesseitigen Freigabeöffnung 33 befindet sich eine Passage 62, durch welche bei der Eindrückbewegung 56 der Schiebeplatte 30 der Schließhals 13 vom Patrizenteil 10 bis zu der aus Fig. 6b ersichtlichen Stellung fährt. In dieser Stellung kann, wie durch eine Strich-Punkt-Linie in Fig. 6b angedeutet ist, der gemäß Fig. 4 eingesteckte Patrizenteil 10 ohne besonderen Kraftaufwand aus dem Matrizenteil 20 im Sinne des Pfeils 48 frei herausgezogen werden. Deswegen kann die Stellung von Fig. 6b als "Entkupplungsstellung" der Schiebeplatte 30 bezeichnet werden.For the decoupling position of Fig. 6b, the sliding plate 30 is by means of a handle 38 in the direction of the arrow 56 in the housing 23 pressed in, against the action of the spring force already mentioned 46. As a result, the spring 36 is deformed accordingly. The mentioned projection 39 seated on the sliding plate 30 comes to the inner end its case-side backdrop 29 to lie. In this decoupling position is the slide 30 with the adjacent section which can be seen in FIG. 2b 32 in axial alignment with the insertion hole on the housing side 24. In this section 32 there is a release opening 33, the clear opening width 55 larger, but at least equal to the aforementioned, 5 shows cross section 54 of the closing head 12 of the male part, which can be seen in FIG 10 is formed. This section 32 is therefore intended as a "release section" be designated. This expanded release opening 33 will through a correspondingly expanded profiling of the two described above Plate legs 34, 35 formed. Between the opening there 22 and the release opening 33 on this side there is a passage 62, through which during the pushing-in movement 56 of the sliding plate 30 the closing neck 13 from the male part 10 to that shown in FIG. 6b Position moves. In this position, like a dash-dot line 6b, the male part inserted according to FIG. 4 is indicated 10 without special effort from the die part 20 in the sense of arrow 48 can be pulled out freely. Therefore the position 6b referred to as the "uncoupling position" of the sliding plate 30 become.

Zur Sicherung der in Fig. 6a ersichtlichen Kupplungsstellung des Schiebers 30 könnte im Bereich der aus Fig. 2b ersichtlichen Passage 62 eine gegenüber dem Durchmesser des Schließhalses 13 elastische Verengung vorliegen, die bei der Eindrückbewegung 56 des Schiebers 30 in die aus Fig. 6b ersichtliche Entkupplungsstellung überwunden wird. Eine solche elastische Deformation kann bei einer derartigen Verengung der Passage 62 durch eine elastische Spreizung der beiden Plattenschenkel 34, 35 hervorgerufen werden.To secure the coupling position of the slide shown in FIG. 6a 30 could be in the area of the passage 62 shown in FIG. 2b compared to the diameter of the neck 13 elastic constriction are present, which during the pushing-in movement 56 of the slide 30 into the 6b apparent position is overcome. Such With such a narrowing, elastic deformation can occur Passage 62 through an elastic expansion of the two plate legs 34, 35 are caused.

Wie bereits eingangs erwähnt wurde, erfolgt die Befestigung des Matrizenteils 20 am Träger 50 durch einen aus Fig. 3a und 3b ersichtlichen Gegenhalter 43. Der Gegenhalter 43 ist ein Ringkörper, der in axialer Richtung in einen Teller 44 mit zahlreichen spitzen, axialen Vorsprüngen 58 und einen von einem Werkzeug zu betätigenden unrunden Abschnitt in Form eines Außensechskants 45 gegliedert ist. Der Gegenhalter 43 wird nach Art einer Mutter von einem Innengewinde 47 axial durchsetzt.As already mentioned at the beginning, the die part is attached 20 on the carrier 50 by means of a counterholder shown in FIGS. 3a and 3b 43. The counter-holder 43 is an annular body, which is in the axial direction in a plate 44 with numerous pointed, axial projections 58 and a non-circular section to be operated by a tool is structured in the form of an external hexagon 45. The counterhold 43 is axially penetrated in the manner of a nut by an internal thread 47.

Das Gehäuse 23 des Matrizenteils 20 besitzt einen mit einem Außengewinde 57 versehenen axialen Ansatz 59, der im Befestigungsfall mit dem Mutterngewinde 47 des Gegenhalters 43 verschraubbar ist. Dazu wird zunächst, wie aus Fig. 4 hervorgeht, an der mit dem Matrizenteil 20 zu versehenen Stelle des Trägers 50 ein Loch 60 eingestanzt, durch welches der Gewindeansatz 59 vom Matrizenteil 20 hindurchgesteckt wird. Dabei kommt das Gehäuse 23 mit seiner Unterfläche an der Schauseite 51 des Trägers 50 zu liegen. Der Gegenhalter 43 wird von der Träger-Rückseite 52 aus aufgeschraubt, wobei seine zugespitzten Vorsprünge 58 in das Material des Trägers 50 eindringen. Auch die Unterfläche des Gehäuses 23 kann, wie Fig. 1c verdeutlicht, mit entsprechenden spitzen Zähnen 61 versehen sein, die im Befestigungsfall in analoger Weise von der Träger-Schauseite 51 aus ins Trägermaterial dringen. Die spitzen Vorsprünge 58 und/oder Zähne 61 sollen den Gegenhalter 43 in seiner Aufschraubposition auf dem Gewindeansatz 59 des Matrizen-Gehäuses 23 sichern.The housing 23 of the die part 20 has one with an external thread 57 provided axial extension 59, which in the attachment case with the Nut thread 47 of the counter holder 43 can be screwed. This will First, as can be seen from FIG. 4, on the part 20 with the die punched a hole 60 to the provided location of the carrier 50 through which the threaded projection 59 is inserted from the die part 20 becomes. The housing 23 comes with its lower surface on the front side 51 of the carrier 50 to lie. The counterholder 43 is the Carrier backside 52 unscrewed with its tapered protrusions 58 penetrate into the material of the carrier 50. Even the bottom surface of the housing 23 can, as FIG. 1c shows, with corresponding pointed teeth 61, which in the case of attachment in analog Penetrate from the carrier face 51 into the carrier material. The pointed projections 58 and / or teeth 61 are intended to hold the counterhold 43 in its screw-on position on the threaded shoulder 59 of the die housing 23 secure.

In Fig. 7a und 7b ist eine alternative Ausbildung 20' des Matrizenteils gezeigt. Der zugehörige Patrizenteil ist analog zu Fig. 5 ausgebildet und besitzt einen Schließkopf 12, dessen Umriß in Fig. 7a und 7b strichpunktiert angedeutet ist. Der Matrizenteil 20' hat einen zum vorausgehenden Ausführungsbeispiel 20 des Matrizenteils weitgehend analogen Aufbau. Der Matrizenteil 20' umfaßt ein Gehäuse 23', das durch unterschiedliche Punktschraffur hervorgehoben ist. Die in grober Punktschraffur hervorgehobenen Bereiche des Gehäuses 23' liegen höher als die eng punktierten.An alternative embodiment 20 'of the die part is shown in FIGS. 7a and 7b shown. The associated male part is designed analogously to FIG. 5 and has a closing head 12, the outline of which is dash-dotted in FIGS. 7a and 7b is indicated. The die part 20 'has one to the previous one Embodiment 20 of the matrix part largely analogous structure. The die part 20 'comprises a housing 23', which by different Dot hatching is highlighted. Those highlighted in rough hatching Areas of the housing 23 'are higher than those closely dotted.

Das Gehäuse 23' hat einen kreisförmigen, in Fig. 1 durch Strichelung verdeutlichten Gehäuseumfang 78, an dem eine hier ringförmig ausgebildete Drehhandhabe 66 drehgelagert ist. Das Gehäuse 23' besitzt ein Einsteckloch 24' für den Patrizenteil, weshalb es durchmessermäßig größer als der erwähnte Schließkopf 12 vom Patrizenteil ausgebildet ist. Dieses Einsteckloch 24' durchsetzt den auch hier vorgesehenen Führungskanal 25', der das Gehäuse 23' diametral durchquert und zur Aufnahme einer gegenüber dem ersten Ausführungsbeispiel abgeänderten Schiebeplatte 30' dient.The housing 23 'has a circular, in Fig. 1 by dashed lines clarified housing circumference 78, on which one here is ring-shaped Rotating handle 66 is rotatably mounted. The housing 23 'has an insertion hole 24 'for the male part, which is why it is larger in diameter than the mentioned closing head 12 is formed by the male part. This Insertion hole 24 'passes through the guide channel also provided here 25 ', which diametrically crosses the housing 23' and for receiving a modified sliding plate compared to the first embodiment 30 'serves.

Auch diese Schiebeplatte 30' ist, im Anschluß an ihr Betätigungsende 37', in zwei Plattenschenkel 34', 35' gegabelt. Diese Plattenschenkel 34', 35' sind in analoger Weise profiliert und lassen sich in den Verriegelungsabschnitt 31' und den Freigabeabschnitt 32' gliedern. Der eine Plattenschenkel 35' ist verlängert und bildet auch hier eine Feder 36', die sich an einer Innenfläche 70 der Drehhandhabe 66 an der Stelle befindet, wo die Drehhandhabe 66 den Führungskanal 25' verschließt. Auch diese Schiebeplatte 30' steht also unter der Wirkung einer Ausschubkraft 46'. Die beiden Plattenschenkel 34', 35' schließen zwischen sich, abschnittweise 31', 32', eine große lichte Weite 55' bzw. kleine lichte Weite 65' ein.This sliding plate 30 'is also, following its actuating end 37 ', forked into two plate legs 34', 35 '. These plate legs 34 ', 35' are profiled in an analogous manner and can be inserted into the locking section 31 'and the release section 32'. The one plate leg 35 'is extended and also forms a spring 36' here is located on an inner surface 70 of the rotating handle 66, where the rotary handle 66 closes the guide channel 25 '. This too Sliding plate 30 'is therefore under the action of an extension force 46'. The two plate legs 34 ', 35' close between them, in sections 31 ', 32', a large clear width 55 'or a small clear width 65'.

Die Drehhandhabe 66 besitzt ein der Schiebeplatte 30' zugekehrtes Innenprofil 67 bis 69, welches im vorliegenden Fall pfeilspitzenförmig ausgebildet ist und zwei in einer Spitze 69 zusammenlaufenden Kanten 67, 68 bestimmt. Dieses Innenprofil 67 bis 69 hat also Konkavform. Diesem Innenprofil 67 bis 69 ist ein Außenprofil 75 bis 77 am Betätigungsende 37' der Schiebeplatte 30 zugeordnet. Dieses besteht im vorliegenden Fall aus einer zur vorerwähnten Konkavform der Drehhandhabe 66 komplementären, ebenfalls pfeilspitzenförmigen Konvexform, nämlich ebenfalls zwei Kanten 75, 76, die in einer gemeinsamen Pfeilspitze 77 zusammenlaufen. Die beiden Spitzen 69, 77 sind zweckmäßigerweise gerundet.The rotary handle 66 has an inner profile facing the sliding plate 30 ' 67 to 69, which in the present case is arrow-shaped and two edges 67 converging in a tip 69, 68 determined. This inner profile 67 to 69 thus has a concave shape. This Inner profile 67 to 69 is an outer profile 75 to 77 at the end of the actuation 37 'assigned to the sliding plate 30. This exists in the present Case of a complementary to the aforementioned concave shape of the rotary handle 66, arrow-shaped convex shape, namely also two edges 75, 76 which converge in a common arrow tip 77. The two tips 69, 77 are expediently rounded.

Die Kanten 67, 68 bzw. 75, 76 sind im vorliegenden Fall geradlinig ausgebildet, doch könnten sie auch eine abweichende Krümmung aufweisen. Das Außenprofil 75 bis 77 der Schiebeplatte 30' könnte in einer gegenüber Fig. 7a, 7b anderen Höhenebene angeordnet sein, wo auch die Drehhandhabe ihr entsprechendes Innenprofil 67 bis 69 besitzt. Es ist nicht erforderlich, beide Profile 67 bis 69 und 75 bis 77 formgleich zu gestalten; es können hier auch zueinander unterschiedliche Profile vorliegen. Im vorliegenden Fall ist das Außenprofil 75 bis 77 von den Außenkanten gebildet, die, in der Plattenebene liegen und die Schiebeplatte 30' in Ausschubrichtung 46' begrenzen.The edges 67, 68 and 75, 76 are straight in the present case, however, they could also have a different curvature. The outer profile 75 to 77 of the sliding plate 30 'could be in one opposite Fig. 7a, 7b other height level, where the rotary handle has its corresponding inner profile 67 to 69. It is not required to design both profiles 67 to 69 and 75 to 77 of the same shape; there may also be different profiles here. In the present case, the outer profile is 75 to 77 from the outer edges formed, which lie in the plane of the plate and the sliding plate 30 'in Limit extension direction 46 '.

Die Lagerung der Drehhandhabe 66 könnte an gesonderten axialen Bereichen des Gehäuses 23' geschehen. Die Drehhandhabe 66 könnte aus einem Ringsegment bestehen. Im vorliegenden Fall besteht sie aber, wie bereits eingangs erwähnt wurde, aus einem kompletten Ring, der das Gehäuse 23' in einem Umfangsbereich 21 allseitig umschließt. Stellenweise besitzt aber die Drehhandhabe 66 Ringsegmente 71, 72, die zwischen sich das vorbeschriebene Innenprofil 67 bis 69 erzeugen. Mit diesen Ringsegmenten 71, 72 ragt die Drehhandhabe 66 wenigstens bereichsweise in den Führungskanal 25' des Gehäuses 23' hinein. Damit wird auch die dort befindliche Kanalöffnung des Führungskanals 25' verschlossen. Durch die Ausschubkraft 46' wird die Schiebeplatte 30' mit ihrem Außenprofil 75 bis 77 stets gegen die dort befindlichen Profilbereiche der Drehhandhabe 66 gedrückt. Dadurch befindet sich die Schiebeplatte 30' in einer von der Drehposition der Drehhandhabe 66 bestimmten Längslage. Dies ist anhand der Fig. 7a und 7b zu erkennen.The storage of the rotary handle 66 could be in separate axial areas of the housing 23 'happen. The rotary handle 66 could be from one Ring segment exist. In the present case, however, it exists how was already mentioned at the beginning, from a complete ring that the Encloses housing 23 'on all sides in a peripheral region 21. In places but has the rotary handle 66 ring segments 71, 72 which between generate the above-described inner profile 67 to 69. With these ring segments 71, 72 the rotary handle 66 projects at least in some areas into the guide channel 25 'of the housing 23'. So that too the channel opening of the guide channel 25 'located there is closed. The pushing force 46 'causes the sliding plate 30' with its outer profile 75 to 77 always against the profile areas of the Rotating handle 66 pressed. As a result, the sliding plate is located 30 'in a longitudinal position determined by the rotational position of the rotary handle 66. This can be seen from FIGS. 7a and 7b.

In Fig. 7a liegt die Ausgangsstellung der Drehhandhabe 66 vor, die dadurch gekennzeichnet ist, daß die Schiebeplatte 30' mit ihrem Außenprofil 75 bis 77 formschlüssig in Flächenanlage am Innenprofil 67 bis 69 der Drehhandhabe 66 anliegt. Im Zusammenwirken mit der Federkraft 46' liegt daher eine definierte Längslage der Schiebeplatte 30' im Führungskanal 25' vor; es befindet sich der Kupplungsabschnitt 31' in axialer Ausrichtung mit dem Gehäuseeinsteckloch 24'.In Fig. 7a, the starting position of the rotary handle 66 is present, which thereby is characterized in that the sliding plate 30 'with its outer profile 75 to 77 form-fitting in surface contact on the inner profile 67 to 69 of the Rotating handle 66 is present. In cooperation with the spring force 46 ' is therefore a defined longitudinal position of the sliding plate 30 'in the guide channel 25 'before; the coupling section 31 'is in axial alignment with the housing insertion hole 24 '.

Wird die Drehhandhabe 66 im Sinne des Pfeils 73 in Fig. 7b verdreht, so wird natürlich auch das zugehörige Innenprofil 67 bis 69 bezüglich des Außenprofils 75 bis 77 der Schiebeplatte 30' verdreht. Wie Fig. 7b zeigt, fährt dabei die Pfeilspitze 77 vom Schieber-Betätigungsende 37' auf die Segmentkante 67 der Drehhandhabe 66 auf und wird um das mit 63 in Fig. 7b gekennzeichnete Wegstück verschoben. Die Schiebeplatte 30' wird also, gegen ihre Federkraft 46', nach innen geschoben und dadurch die federwirksame Schenkelverlängerung 36' gestaucht. Jetzt ist, analog zu Fig. 6b, der Freigabeabschnitt 32' mit dem Einsteckloch 24' des Gehäuses 23' ausgerichtet. Es liegt die Freigabestellung der Schiebeplatte 30' vor.If the turning handle 66 is turned in the direction of arrow 73 in FIG. 7b, the associated inner profile 67 to 69 will of course also be related of the outer profile 75 to 77 of the sliding plate 30 'rotated. As Fig. 7b shows the arrowhead 77 moves from the slide actuation end 37 'on the segment edge 67 of the rotary handle 66 and is around the distance marked 63 in Fig. 7b shifted. The sliding plate 30 'is thus pushed inwards against its spring force 46' and thereby the spring-effective leg extension 36 'is compressed. Now, analogous to FIG. 6b, the release section 32 'with the insertion hole 24 'of the housing 23' aligned. It is the release position the sliding plate 30 '.

Die in Fig. 7b gezeigte Drehposition kann durch innere Endanschläge definiert sein. Diese Endanschläge können beispielsweise aus Bereichen der Schiebeplatte 30' bestehen oder aber aus Teilen im Inneren des Gehäuses 23' gebildet sein.The rotational position shown in Fig. 7b can be by internal end stops be defined. These end stops can be from areas, for example the sliding plate 30 'or consist of parts inside the housing 23 'be formed.

Wenn die in Fig. 7b gezeigte Drehstellung vorliegt, wo die Innenprofil-Kante 67 noch eine Neigungslage zur Wirkrichtung der Ausschubkraft 46' aufweist, so entsteht eine von dieser Ausschubkraft 46' abgeleitete Kraftkomponente, die ein in Fig. 7b durch den Pfeil 74 verdeutlichtes Rückstell-Drehmoment auf die Drehhandhabe 66 ausübt. Läßt die menschliche Hand die Drehhandhabe 66 in der Drehstellung von Fig. 7b los, so erfolgt eine selbsttätige Rückdrehung 74 der Drehhandhabe 66. Die Drehhandhabe 66 wird solange zurückgedreht, bis die aus Fig. 7a ersichtliche Ausgangsstellung vorliegt. In dieser Ausgangsstellung befindet sich die Schiebeplatte 30' in ihrer maximal ausgefahrenen Lage. Es liegt eine vollflächige Anlage zwischen den Innenprofilen 67 bis 69 und Außenprofilen 75 bis 77 vor; die beiden Pfeilspitzen 69, 77 sind miteinander ausgerichtet. Das auf die Drehhandhabe 66 bis dahin wirkende Drehmoment 74 ist verschwunden. Es liegt folglich eine gesicherte Ausgangsstellung der Schiebeplatte 30' vor.If the rotational position shown in Fig. 7b is where the inner profile edge 67 another inclination to the direction of action of the extension force 46 ', a force derived from this extension force 46' is created Force component, which is illustrated in FIG. 7b by arrow 74 Restoring torque exerts on the rotary handle 66. Leaves the human Release the rotary handle 66 in the rotary position of FIG. 7b, so there is an automatic reverse rotation 74 of the rotary handle 66. Die The turning handle 66 is turned back until the one shown in FIG. 7a Starting position is present. Is in this starting position the sliding plate 30 'in its maximum extended position. It lies a full-surface system between the inner profiles 67 to 69 and outer profiles 75 to 77 before; the two arrow heads 69, 77 are together aligned. The torque acting on the turning handle 66 until then 74 has disappeared. There is therefore a secure starting position the sliding plate 30 '.

Es versteht sich, daß die auf die Schiebeplatte 30' einwirkende Ausschubkraft 46' auch von einer gesonderten Feder erzeugt sein könnte, die nicht, wie im vorliegenden Fall, einstückig mit der Schiebeplatte 30' ausgebildet ist. Die Ausbildung der Drehhandhabe 66 könnte jede beliebige Form aufweisen und z. B. schauseitig auf dem Gehäuse 23' des Matrizenteils 20' angeordnet sein. In diesem Fall könnte zum Erfassen mit der menschlichen Hand eine diametrale Rippe an der Drehhandhabe vorgesehen sein.It is understood that the pushing force acting on the sliding plate 30 ' 46 'could also be generated by a separate spring, the not, as in the present case, in one piece with the sliding plate 30 ' is trained. The formation of the rotary handle 66 could be any Have shape and z. B. on the view side on the housing 23 'of the die part 20 'may be arranged. In this case, you could use the human hand is provided with a diametrical rib on the rotating handle his.
