Abstract

A limitedly shiftable overlap connection between two platelike parts, as between a U-rail and a covering or blocking platelet of connection rod fittings in which the parts can be brought into connection with one another through a simple snap plug coupling without the need for riveting or welding.

Description

Die Erfindung betrifft einen Beschlag für Fenster, Türen o. dgl. mit einer Stoßstelle zwischen zwei in gleicher Ebene hintereinanderliegenden Stulpschienen und einem diese Stoßstelle abdeckenden Arretierplättchen, bei welchem entweder das Ende der einen Stulpschiene oder das Arretierplättchen ein Langloch aufweist, das von einem Zapfen oder Steg entweder des Arretierplättchens oder der Stulpschiene durchgriffen ist, dessen freies Ende mit einem Kragen oder Bund die Längsränder des Langloches seitwärts überragt und eine durch die Länge des Langlochs begrenzte, verschiebliche Verbindung zwischen der Stulpschiene und dem Arretierplättchen bildet.The invention relates to a fitting for windows, doors or the like. With a butt joint between two faceplates lying one behind the other in the same plane and a locking plate covering this butt joint, in which either the end of a faceplate or the locking plate has an elongated hole that is from a pin or The web of either the locking plate or the faceplate is penetrated, the free end of which with a collar or collar projects laterally beyond the longitudinal edges of the elongated hole and forms a displaceable connection between the faceplate and the locking plate which is limited by the length of the elongated hole.

Beschläge dieser Art zur Bildung von Überlappungsverbindungen sind bereits bekannt und beispielsweise im DE-U- 77 02 352, im DE-U- 79 35 685 sowie im DE-U- 81 21 766 offenbart.Fittings of this type for forming overlap connections are already known and are disclosed, for example, in DE-U-77 02 352, in DE-U-79 35 685 and in DE-U-81 21 766.

Alle diese bekannten Beschläge mit Überlappungsverbindungen erfordern jedoch einen beträchtlichen Fertigungsaufwand, weil nämlich die begrenzt verschiebliche Verbindung zwischen den beiden plattenförmigen Teilen mittels des Zapfens oder Steges durch einen besonderen Fertigungsvorgang, nämlich einen Niet- oder Schweißvorgang, bewirkt werden muß, der wiederum erst durchgeführt werden kann, nachdem der Zapfen oder Steg relativ zu den beiden plattenförmigen Teilen in die erforderliche Eingriffs- bzw. Befestigungslage gebracht worden ist.All these known fittings with overlap connections, however, require a considerable amount of production work, because namely the limited sliding connection between the two plate-shaped parts by means of the pin or web must be brought about by a special production process, namely a riveting or welding process, which in turn can only be carried out after the pin or web has been brought into the required engagement or fastening position relative to the two plate-shaped parts.

Für eine rationelle Massenfertigung, wie sie beispielsweise bei Treibstangenbeschlägen üblich ist, erfordert daher die Bildung der bekannten Überlappungsverbindungen einen beträchtlichen Anlagenaufwand.For a rational mass production, as is common, for example, in connecting rod fittings, the formation of the known overlap connections therefore requires considerable outlay on equipment.

Mit der Erfindung wird die Beseitigung dieses erheblichen Mangels bezweckt. Deshalb liegt der Erfindung die Aufgabe zugrunde, eine Überlappungsverbindung der eingangs angegebenen Gattung zu schaffen, die sich unter Vermeidung von Niet und Schweißvorgängen durch einen einfachen Steckvorgang bilden läßt und trotzdem für den vorgesehenen Einsatzzweck funktionssicher ist.The purpose of the invention is to remedy this considerable defect. Therefore, the invention has for its object to provide an overlap connection of the type specified, which can be formed by avoiding rivets and welding processes by a simple plug-in process and is still reliable for the intended purpose.

Erreicht wird das gesteckte Ziel nach der Erfindung durch die Kennzeichnungsmerkmale des Anspruchs 1, nämlich dadurch,
daß das zu einer Querkante oder in einen Erweiterungsabschnitt ausmündende Langloch in seiner Mündungsöffnung wenigstens an einem Längsrand eine hakenartige Einschnürung mit quer gerichteter Anschlagschulter aufweist, derart,
daß der Zapfen oder Steg von der Mündungsöffnung aus in das Langloch einführbar aber nicht rückführbar ist,
und daß dabei die Länge des Langloches dem Abstand der quer gerichteten Anschlagschulter vom inneren Langlochende entspricht.
The set aim according to the invention is achieved by the characterizing features of claim 1, namely by
that the elongated hole opening into a transverse edge or into an extension section has a hook-like constriction with a transversely directed stop shoulder in its opening at least on one longitudinal edge, such that
that the pin or web can be inserted into the elongated hole from the mouth opening but cannot be returned,
and that the length of the slot corresponds to the distance of the transverse stop shoulder from the inner slot end.

Zur Bildung der Überlappungsverbindung braucht in diesem Falle das den Zapfen oder Steg aufweisende plattenförmige Teil mit seinem Zapfen oder Steg lediglich vor die Mündungsöffnung geführt und sodann durch diese in das Langloch eingeschoben zu werden, wobei dann zunächst die hakenartige Einschnürung elastisch nach der Seite ausweicht und anschließend wieder in ihre Grundstellung zurückkehrt, so daß sie den in das Langloch eingeführten Zapfen oder Steg schnäpperartig hinterfaßt und damit den Verschiebeweg des plattenförmigen Teils selbsttätig begrenzt.To form the overlap connection in this case, the plate-shaped part having the pin or web need only be guided with its pin or web in front of the mouth opening and then inserted through the latter into the elongated hole, the hook-like constriction then first elastically evading to the side and then returns to its basic position so that it snaps behind the pin or web inserted into the slot and thus automatically limits the displacement of the plate-shaped part.

Durch die GB-A- 2 010 376 ist eine Halteklammer zur Bildung eines Schnappverschlusses bekannt, welche die beiden zu verbindenden Teile, beispielsweise eine Blechplatte und eine Befestigungsvorrichtung, in einer vorgegebenen - unverschieblichen - Position zueinander hält.From GB-A-2 010 376 a retaining clip for forming a snap lock is known which, for example, the two parts to be connected holds a sheet metal plate and a fastening device in a predetermined - immovable - position to each other.

Dieser Schnappverschluß läßt zwar das Einrücken eines Kopfbolzens hinter hakenartige Einschnürungen in der Nähe der Endwand eines durch Seitenwände begrenzten Schlitzes zu. Hier wird jedoch der Kopfbolzen zwischen Rastnasen und der Endwand des Schlitzes unverschiebbar fixiert. Dabei sind die Flanken der Rastnasen so abgerundet bzw. abgeschrägt ausgeführt, daß durch seitliche Krafteinwirkung auf den Kopfbolzen in Richtung von der Endwand des Schlitzes weg ein Ausrasten des Schnappverschlusses aus der vorgegebenen bzw. festliegenden Eingriffsstellung herbeigeführt werden kann.This snap lock allows the insertion of a head bolt behind hook-like constrictions near the end wall of a slot delimited by side walls. Here, however, the headed pin is fixed immovably between the locking lugs and the end wall of the slot. The flanks of the locking lugs are rounded off or beveled so that the snap lock can be disengaged from the predetermined or fixed engagement position by lateral force acting on the head bolt in the direction away from the end wall of the slot.

Als besonders vorteilhaft hat sich erfindungsgemäß gezeigt, wenn gemäß Anspruch 2 beide Längsränder des Langlochs mit je einer hakenartigen Einschnürung versehen sind und beide Einschnürungen eine zueinander spiegelbildliche Ausbildung haben. Die Funktionssicherheit der Überlappungsverbindung wird durch diese Ausgestaltung erhöht.It has been shown to be particularly advantageous if, according to claim 2, both longitudinal edges of the elongated hole are each provided with a hook-like constriction and both constrictions have a mirror image of one another. The functional reliability of the overlap connection is increased by this configuration.

Nach Anspruch 3 sieht die Erfindung des weiteren vor, daß jede Einschnürung eine sich zur Querkante bzw. zum Erweiterungsabschnitt der Stulpschiene erstreckende, divergierende Einlaufflanke hat.According to claim 3, the invention further provides that each constriction has a diverging inlet flank which extends to the transverse edge or to the extension section of the faceplate.

Nach Anspruch 4 soll erfindungsgemäß der Zapfen oder Steg einen T-förmigen Querschnitt haben sowie eine rechteckig begrenzte Profilleiste aufweisen, die lediglich längsschiebbar, aber drehfest in das Langloch einrückbar ist.According to claim 4, the pin or web according to the invention should have a T-shaped cross section and have a rectangularly delimited profile strip which can only be pushed longitudinally, but can be inserted into the elongated hole in a rotationally fixed manner.

Als besonders vorteilhaft hat sich schließlich eine Ausbildung erwiesen, bei welcher gemäß Anspruch 5 der Abstand zwischen den divergierenden Einlaufflanken der Einschnürungen an der Mündungsöffnung geringfügig größer als die Breite der Profilleiste bemessen ist, während der Abstand im Bereich der Anschlagschultern kleiner als die Breite der Profilleiste vorgesehen ist.Finally, a design has proven to be particularly advantageous in which, according to claim 5, the distance between the diverging inlet flanks of the constrictions at the mouth opening is dimensioned slightly larger than the width of the profile strip, while the distance in the region of the stop shoulders is smaller than the width of the profile strip is.

Das den Zapfen oder Steg aufweisende Teil der Überlappungsverbindung kann mit dem Zapfen oder Steg gemäß Anspruch 6 einstückig, beispielsweise aus Metall-Druckguß oder auch Kunststoff-Spritzgruß gefertigt sein.The part of the overlap connection having the pin or web can be made in one piece with the pin or web according to claim 6, for example from die-cast metal or plastic injection molding.

Es kann aber auch gemäß Anspruch 7 einstückig als Stanz-Prägeteil aus einem Blechzuschnitt gebildet werden.But it can also be formed in one piece as a stamped-embossed part from a sheet metal blank.

Schließlich hat es sich nach Anspruch 8 auch noch als zweckmäßig erwiesen, wenn das den Zapfen oder Steg aufweisende Teil an seiner Unterseite mindestens an zwei sich diagonal gegenüberliegenden Ecken mit noppenartigen Erhöhungen versehen ist, die bei gleichzeitiger Auflage auf dem das Langloch enthaltende Teil als Klemmkörper wirksam sind.Finally, it has also proven to be expedient if the part having the pin or web is provided on its underside at least at two diagonally opposite corners with nub-like elevations, which act as a clamping body while resting on the part containing the elongated hole are.

Die in Zeichnung dargestellte Überlappungsverbindung 1 besteht aus zwei plattenförmigen Teilen 2 und 3.The overlap connection 1 shown in the drawing consists of two plate-shaped parts 2 and 3.

Das eine plattenförmige Teil bildet dabei nach den in der Zeichnung gezeigten Ausführungsbeispielen die Stulpschiene 2 eines Treibstangenbeschlages, während das zweite plattenförmige Teil ein zugehöriges Abdeck- bzw. Arretierplättchen 3 ist, mit dessen Hilfe die Stoßstelle 4 zwischen zwei in gleicher Ebene hintereinanderliegenden Stulpschienen 2 und 5 eines Treibstangenbeschlages überbrückt werden kann, wie das ein Vergleich der Fig. 3 und 4 deutlich macht.According to the exemplary embodiments shown in the drawing, the one plate-shaped part forms the faceplate 2 of an espagnolette fitting, while the second plate-shaped part is an associated cover or locking plate 3, with the aid of which the joint 4 between two faceplates 2 and 5 lying one behind the other in the same plane a connecting rod fitting can be bridged, as is clear from a comparison of FIGS. 3 and 4.

Eine Überlappungsverbindung der in der Zeichnung dargestellten Art kann ggf. aber auch im Bereich der Stoßkanten zwischen zwei in gleicher Ebene aneinanderliegenden, relativ dünnen Schichtkörpern, wie z. B. Kunststoffplatten oder Blechtafeln vorgesehen werden, wenn dies wünschenswert oder zweckmäßig erscheint.An overlap connection of the type shown in the drawing can, however, possibly also in the region of the abutting edges between two relatively thin layered bodies lying against one another in the same plane, such as, for. B. plastic plates or sheets are provided if this appears desirable or appropriate.

Das eine plattenförmige Teil, nach den Ausführungsbeispielen nämlich die Stulpschiene 2, ist im Bereich des Endabschnitts 6 mit einem Langloch 7 versehen, welches eine vorgegebene Länge 8 und eine ebenfalls vorgegebene Breite 9 aufweist.One plate-shaped part, namely the faceplate 2 according to the exemplary embodiments, is provided in the region of the end section 6 with an elongated hole 7 which has a predetermined length 8 and a likewise predetermined width 9.

Beim Ausführungsbeispiel nach den Fig. 1 bis 4 mündet dabei dieses Langloch 7 an einer Querkante 10 der Stulpschiene aus, wobei dort eine Mündungsöffnung 11 gebildet ist, die an beiden Längsrändern des Langloches 7 jeweils durch eine hakenartige Einschnürung 12 begrenzt ist.In the exemplary embodiment according to FIGS. 1 to 4, this elongated hole 7 opens out at a transverse edge 10 of the faceplate, an opening 11 being formed there, which is delimited on both longitudinal edges of the elongated hole 7 by a hook-like constriction 12.

Die beiden hakenartigen Einschnürungen 12 haben dabei eine zueinander spiegelbildliche Ausbildung und bestehen jeweils aus einer quer zur Längsrichtung des Langloches 7 gerichteten Anschlagschulter 13 und einer von dieser aus zur Querkante 12 hin divergierenden Einlaufflanke 14.The two hook-like constrictions 12 have a mirror image of one another and each consist of a stop shoulder 13 directed transversely to the longitudinal direction of the elongated hole 7 and an inlet flank 14 diverging from the latter towards the transverse edge 12.

Zwischen den einander zugewendeten Enden der Anschlagschultern 13 hat dabei die Mündungsöffnung 11 eine Breite 15, die beträchtlich kleiner bemessen ist als die Breite 9 des Langloches 7. Andererseits weist die Mündungsöffnung 11 im Bereich der Querkante 10 der Stulpschiene 2 eine Breite 16 auf, die mindestens gleich, vorzugsweise jedoch geringfügig größer als die Breite 9 des Langloches 7 bemessen ist.Between the mutually facing ends of the stop shoulders 13, the mouth opening 11 has a width 15 that is dimensioned considerably smaller than the width 9 of the elongated hole 7. On the other hand, the mouth opening 11 in the region of the transverse edge 10 of the faceplate 2 has a width 16 that is at least is the same, but preferably slightly larger than the width 9 of the elongated hole 7.

Das als Abdeck- bzw. Arretierplättchen 3 dienende plattenförmige Teil der Überlappungsverbindung 1 kann gemäß den Fig. 1 bis 4 als Formteil aus Metall-Druckguß, beispielsweise Zinkdruckguß, oder aber aus Kunststoff-Spritzguß hergestellt sein, wobei von seiner Unterseite ein Zapfen oder Steg 17 absteht, der sich in Längsrichtung des Abdeck- bzw. Arretierplättchens 3 erstreckt. Dieser Zapfen oder Steg 17 hat dabei einen etwa T-förmigen Querschnitt mit einer rechtwinklig von der Unterseite des Abdeck- bzw. Arretierplättchens 3 abstehenden Profilleiste 18, die zwei zueinander parallele Längsflächen aufweist, vorzugsweise in ihrer Profilform rechteckig begrenzt ist. Im Abstand von der Unterseite des Abdeck- bzw. Arretierplättchens 3 schließen sich an die Profilleiste 18 die beiden nach entgegengesetzten Seiten gerichteten T-Flansche 19 an.The plate-shaped part of the overlap connection 1 serving as a covering or locking plate 3 can be produced according to FIGS. 1 to 4 as a molded part from die-cast metal, for example die-cast zinc, or from injection-molded plastic, with a pin or web 17 from its underside protrudes, which extends in the longitudinal direction of the cover or locking plate 3. This pin or web 17 has an approximately T-shaped cross section with a profile strip 18 protruding at right angles from the underside of the cover or locking plate 3, which has two mutually parallel longitudinal surfaces, preferably rectangularly limited in their profile shape. At a distance from the underside of the cover or locking plate 3, the two T-flanges 19 directed towards opposite sides adjoin the profile strip 18.

Die Breite 20 der Profilleiste 18 des Zapfen oder Steges 17 ist auf die Breite 9 des Langloches 7 in der Stulpschiene 2 abgestimmt, dergestalt, daß sie mit diesem Langloch 7 lediglich längsschiebbar, aber drehfest in Wirkverbindung gebracht werden kann.The width 20 of the profile strip 18 of the pin or web 17 is matched to the width 9 of the elongated hole 7 in the faceplate 2 in such a way that it can be brought into operative connection with this elongated hole 7 only in a longitudinally slidable but rotationally fixed manner.

Die beiden T-Flansche 19 des Steges oder Zapfens 17 stehen seitwärts so über die Profilleiste 18 vor, daß sie die Längskanten des Langloches 7 in der Stulpschiene 7 seitwärts übergreifen können, sobald der Zapfen oder Steg 17 mit diesem in Führungseingriff gebracht ist.The two T-flanges 19 of the web or pin 17 project laterally over the profile strip 18 so that they can overlap the longitudinal edges of the elongated hole 7 in the faceplate 7 as soon as the pin or web 17 is brought into engagement with it.

Zum Kuppeln des Abdeck- bzw. Arretierplättchens 3 mit der Stulpschiene 2 ist es lediglich notwendig, den an seine Unterseite angeformten Zapfen oder Steg 17 mit seiner Profilleiste 18 in den Bereich der Mündungsöffnung 11 zu führen und dann eine Längskraft auf das Abdeck- bzw. Arretierplättchen 3 auszuüben. Die Längsleiste 18 trifft dann nämlich auf die zur Querkante 10 hin divergierenden Einlaufflanken 14 der beiden hakenartigen Einschnürungen 12 und drückt diese dadurch in der Ebene der Stulpschiene 2 unter elastischer Verformung der das Langloch 7 in Längsrichtung begrenzenden Abschnitte der Stulpschiene 2 auseinander, bis die Profilleiste 18 insgesamt im Bereich des Langloches 7 liegt. In diesem Augenblick bewegen sich die hakenartigen Einschnürungen 12 aufgrund der elastischen Rückstellkräfte wieder in ihre ursprüngliche Lage zurück, so daß die einander zugewendeten Enden ihrer Anschlagschultern 13 wieder den geringen Abstand 15 zueinander einnehmen. Die Anschlagschultern 13 des Langloches 7 können dann mit einer Widerlagerschulter 21 an der Profilleiste 18 des Zapfens oder Steges 17 zusammenwirken und dadurch den Verschiebeweg des Zapfens bzw. Steges 17 innerhalb des Langloches 7 sowie folglich auch den Verschiebeweg des Abdeck-bzw. Arretierplättchens 3 in Längsrichtung der Stulpschiene 2 begrenzen.To couple the cover or locking plate 3 with the faceplate 2, it is only necessary to form the pin formed on its underside or web 17 with its profile strip 18 in the area of the mouth opening 11 and then exert a longitudinal force on the cover or locking plate 3. The longitudinal bar 18 then namely meets the inlet flanks 14 of the two hook-like constrictions 12 diverging towards the transverse edge 10 and thereby presses them apart in the plane of the faceplate 2 with elastic deformation of the sections of the faceplate 2 delimiting the slot 7 in the longitudinal direction until the profile bar 18 lies overall in the area of the elongated hole 7. At this moment, the hook-like constrictions 12 move back into their original position due to the elastic restoring forces, so that the ends of their stop shoulders 13 facing each other again take up the small distance 15 from one another. The stop shoulders 13 of the slot 7 can then cooperate with an abutment shoulder 21 on the profile strip 18 of the pin or web 17 and thereby the displacement path of the pin or web 17 within the slot 7 and consequently also the displacement path of the cover or. Limit the locking plate 3 in the longitudinal direction of the faceplate 2.

In der einen Schiebe-Endstellung nimmt dabei das Abdeck- bzw. Arretierplättchen 3 relativ zur Stulpschiene 2 die aus den Fig. 2 und 3 ersichtliche Lage ein, während es in der anderen Schiebeendstellung die aus Fig. 4 erkennbare Relativlage hat.In one sliding end position, the cover or locking plate 3 relative to the faceplate 2 assumes the position shown in FIGS. 2 and 3, while in the other sliding end position it has the relative position shown in FIG. 4.

Wesentliches Kriterium der Überlappungsverbindung 1 ist, daß Stulpschiene 2 und Abdeck- bzw. Arretierplättchen 3 durch eine einfache Steckmontage miteinander in Verbindung gebracht werden können, daß also keinerlei Niet-und/oder Schweißarbeiten durchgeführt werden müssen.An essential criterion of the overlap connection 1 is that the faceplate 2 and the cover or locking plate 3 can be connected to one another by a simple plug-in assembly, so that no riveting and / or welding work has to be carried out.

Die in Fig. 5 gezeigte Bauart einer Überlappungsverbindung 1 unterscheidet sich von derjenigen nach den Fig. 1 bis 4 einerseits nur dadurch, daß die Mündungsöffnung 11 zwischen den beiden hakenartigen Einschnürungen 12 nicht an der Querkante 10 der Stulpschiene ausläuft, sondern in einen mit Abstand vor diese Querkante 10 in die Stulpschiene 2 eingeschnittenen Erweiterungsabschnitt 22. Dieser Erweiterungsabschnitt 22 ist dabei so gestaltet, daß in seinem Bereich das Abdeck- bzw. Arretierplättchen 3 mit den T-Flanschen 19 seines Zapfens oder Steges 17 quer zur Ebene der Stulpschiene 2 eingesteckt werden kann, woraufhin dann die Profilleiste 18 des Zapfens oder Steges 17 durch Ausübung einer Längskraft auf das Abdeck- bzw. Arretierplättchen 3 in das Langloch 7 einrückbar ist.The type of overlap connection 1 shown in FIG. 5 differs from that according to FIGS. 1 to 4 on the one hand only in that the mouth opening 11 between the two hook-like constrictions 12 does not run out at the transverse edge 10 of the faceplate, but into one at a distance this transverse edge 10 cut into the faceplate 2 Extension section 22. This extension section 22 is designed so that in its area the cover or locking plate 3 with the T-flanges 19 of its pin or web 17 can be inserted transversely to the plane of the faceplate 2, whereupon the profile strip 18 of the pin or web 17 can be pushed into the elongated hole 7 by exerting a longitudinal force on the covering or locking plate 3.

Das Abdeck- bzw. Arretierplättchen 3 kann auch bei der Ausgestaltung der Überlappungsverbindung 1 nach Fig. 5 aus einem Metall-Druckguß-oder einem Kunststoff-Spritzguß-Formteil bestehen, wie es inbesondere in Fig. 1 zu sehen ist.The cover or locking plate 3 can also consist in the configuration of the overlap connection 1 according to FIG. 5 from a metal die-cast or a plastic injection-molded part, as can be seen in particular in FIG. 1.

Es besteht jedoch auch die Möglichkeit, ein als Stanz-Prägeteil aus Blech gefertigtes Abdeck- bzw. Arretierplättchen 3 zu benutzen, bei dem, wie in Fig. 5 gezeigt, der Zapfen oder Steg 17 mit seiner Profilleiste 18 und den beiden T-Flanschen 19 durch Stanzschnitte aus der Blechebene herausgetrennt und durch anschließenden Prägedruck über die Unterseite des Blechzuschnitts herausgeformt wird.However, there is also the possibility of using a cover or locking plate 3 made as a stamped-stamped part made of sheet metal, in which, as shown in FIG. 5, the pin or web 17 with its profile strip 18 and the two T-flanges 19 is cut out of the sheet metal plane by means of punch cuts and is then shaped out by means of subsequent embossing printing over the underside of the sheet metal blank.

Das Zusammenwirken des als Stanz-Prägeteil gefertigten Abdeck- bzw. Arretierplättchens 3 nach Fig. 5 mit der Stulpschiene 2 unterscheidet sich jedoch nicht vom Abdeck- bzw. Arretierplättchen 3 nach den Fig. 1 bis 4.The interaction of the cover or locking plate 3 manufactured as a stamped / stamped part according to FIG. 5 with the faceplate 2 does not differ from the cover or locking plate 3 according to FIGS. 1 to 4.

Aus Fig. 1 ist noch ersichtlich, daß das Abdeck- bzw. Arretierplättchen 3 an seiner Unterseite mindestens an zwei sich diagonal gegenüberliegenden Ecken je eine noppenartige Erhöhung 23 aufweisen kann. Bei gleichzeitiger Auflage dieser Erhöhungen 23 auf der Oberseite der Stulpschiene 2, also in der zurückgeschobenen Stellung des Abdeck- bzw. Arretierplättchens 3, gemäß Fig. 3 ergibt sich im Zusammenwirken mit den T-Flanschen 19 des Zapfens oder Stegs 17 eine Klemmwirkung. Auf einfache Art und Weise kann damit einem unerwünschte, Vorschieben des Abdeck- bzw. Arretierplättchens 3 relativ zur Stulpschiene 2 entgegengewirkt werden.From Fig. 1 it can also be seen that the cover or locking plate 3 can have a knob-like elevation 23 on its underside at least at two diagonally opposite corners. When these ridges 23 are placed on top of the faceplate 2, that is to say in the retracted position of the cover or locking plate 3, as shown in FIG. In this way, an undesired advancement of the covering or locking plate 3 relative to the faceplate 2 can be counteracted in a simple manner.

Die Fig. 4 läßt erkennen, daß die im Abdeck- bzw. Arretierplättchen 3 vorgesehenen Senklöcher als Aufnahmen für Schrauben benutzt werden können, die jeweils die Stulpschienen 2 und 5 durchdringen. Es wird hierdurch in der Wirkstellung der Überlappungsverbindung 1 nach Fig. 4 eine mechanisiche Verkettung der Stulpschienen 2 und 5 über das Abdeck- bzw. Arretierplättchen herbeigeführt.Fig. 4 shows that the countersunk holes provided in the cover or locking plate 3 can be used as receptacles for screws which penetrate the face plates 2 and 5, respectively. In this way, in the operative position of the overlap connection 1 according to FIG. 4, a mechanical concatenation of the face plates 2 and 5 is brought about via the cover or locking plate.
