Description

Die Erfindung betrifft ein Fenster mit aufgesetztem Sprossengitter, gemäss dem Oberbegriff des Anspruchs 1, wie es durch das DE-GM 8 317 035 bekannt ist.The invention relates to a window with a rung grille, according to the preamble of claim 1, as is known from DE-GM 8 317 035.

Das bekannte Sprossengitter ist aus durchgehenden sowie zu diesen quer verlaufenden Sprossen gebildet, welche jeweils aus Hohlprofilstäben hergestellt sind, die einen regelmässig trapezförmigen Querschnitt aufweisen.The known lattice grating is formed from continuous and transverse to these rungs, which are each made of hollow profile bars that have a regularly trapezoidal cross section.

An den Kreuzverbindungsstellen zwischen durchgehenden und querverlaufenden Sprossen sind an den durchgehenden Sprossen sich beiderseits von diesen auswärts erstreckende Zapfen angeordnet, die einen solchen Querschnitt aufweisen, dass sich die Hohlprofilstäbe der quer verlaufenden Sprossen auf diese Zapfen aufschieben lassen.At the cross-connection points between continuous and transverse rungs are arranged on the continuous rungs on both sides of these outwardly extending pins which have a cross section such that the hollow profile bars of the transverse rungs can be pushed onto these pins.

Die Zapfen sind aus einem durchgehenden Profilabschnitt gebildet, der durch komplementär zu seiner Querschnittskontur ausgebildete Aussparungen in den gegenüberliegenden Seitenwänden der durchgehenden Sprosse hindurchgeschoben ist und mit dieser Sprosse verklebt ist.The pins are formed from a continuous profile section which is pushed through recesses formed complementarily to its cross-sectional contour in the opposite side walls of the continuous rung and is glued to this rung.

Ein solches Sprossengitter hat den Nachteil, dass die Aussparungen nur schwierig herstellbar sind. Ausserdem grenzen Klebstellen unmittelbar an Sichtflächen der durchgehenden Sprosse an, so dass auch bei sorgfältiger Verarbeitung das störend sichtbare Austreten von Kleber nicht immer vermeidbar ist.Such a rung grid has the disadvantage that the cutouts are difficult to produce. In addition, glue points directly adjoin the visible surfaces of the continuous rung, so that even with careful processing, the annoyingly visible leakage of glue is not always avoidable.

Ein weiteres Problem liegt darin, dass bei Verwendung eines Hohlprofilstabes aus Metall, der aussen mit Kunststoff beschichtet ist, der Kleber oft am Metall nicht oder nur schlecht anhaftet.Another problem lies in the fact that when using a hollow profile rod made of metal, which is coated on the outside with plastic, the adhesive often does not adhere or only adheres poorly to the metal.

Solche Sprossen haben andererseits oftmals eine strukturierte, gegebenenfalls auch farblich gestaltete Oberfläche. Diese kann wiederum ihrerseits vom Kleber angegriffen werden.On the other hand, such rungs often have a structured, possibly also colored surface. This in turn can be attacked by the adhesive.

Wegen des grossen Aufwandes bei der Herstellung der trapezförmigen Aussparungen sind diese mit einfachen Werkstattmitteln nur schwer herstellbar.Because of the great effort involved in producing the trapezoidal recesses, they are difficult to produce with simple workshop means.

Gleiches gilt auch für das Aufbringen der Verklebung, da zum Auftragen des Klebers wegen der beschriebenen hohen Verschmutzungsgefahr Erfahrung, Übung und besondere Einrichtungen erforderlich sind.The same also applies to the application of the adhesive, since experience, practice and special facilities are required to apply the adhesive because of the high risk of contamination described.

Ausgehend von dieser Problemlage liegt daher der Erfindung die Aufgabe zugrunde, für das eingangs genannte, bekannte Fenster mit aufgesetztem Sprossengitter eine leicht herstellbare, saubere Verbindung zu schaffen. Diese Aufgabe wird erfindungsgemäss durch die Merkmale des Anspruchs 1 gelöst.Based on this problem, the object of the invention is to create an easy-to-produce, clean connection for the known window with a lattice grille attached. According to the invention, this object is achieved by the features of claim 1.

Hierbei werden nicht, wie bei dem bekannten Sprossengitter, die beiden Zapfen durch einen durchgehenden Profilabschnitt gebildet, sondern die beiden Zapfen sind als Einzelzapfen ausgebildet und durchdringen das Profil der durchgehenden Sprosse nicht mit ihrem gesamten Querschnitt, sondern weisen lediglich überstehende Finger auf, die in diesen zugeordnete Parallelbohrungen in der Sprosse eingesetzt und geführt sind.Here, as in the known rung grid, the two pegs are not formed by a continuous profile section, but the two pegs are designed as individual pegs and do not penetrate the profile of the continuous rung with their entire cross section, but only have protruding fingers in them assigned parallel bores are inserted and guided in the rung.

Während die Zapfen als Druckgussteile hergestellt und geliefert werden können, ist bei dem Profilmaterial zur Herstellung der durchgehenden Sprossen die Anbringung zweier Parallelbohrungen mit ausreichender Genauigkeit selbst schlecht eingerichteten Handwerksbetrieben möglich. Somit kann das gesamte Sprossengitter leicht und sauber werkstattseitig mit allen seinen Kreuzverbindungsstellen hergestellt werden, wobei Konstruktionsänderungen jederzeig berücksichtigt werden können.While the pegs can be manufactured and supplied as die-cast parts, the profile material used to manufacture the continuous rungs allows two parallel holes to be made with sufficient accuracy, even in poorly set-up workshops. This means that the entire rung grille can be easily and neatly manufactured in the workshop with all its cross-connection points, whereby design changes can be taken into account at any time.

Es ist möglich, für die durchgehenden Sprossen massive Stäbe zu verwenden, da das Einbringen von Parallelbohrungen in diese keinerlei Schwierigkeiten bietet.It is possible to use solid bars for the continuous rungs, since the introduction of parallel holes in them does not pose any difficulties.

Ein besonderer Vorteil der erfindungsgemässen Zapfen liegt aber darin, dass sie ohne die Verwendung von Klebstoff an der durchgehenden Sprosse befestigt werden können. Es ist beispielsweise möglich, die Parallelbohrungen derart zu bemessen, dass die Finger in sie eingepresstwerden können und mit Klemmsitz in diesen sitzen. Erfindungsgemäss ist es aber besonders von Vorteil, dass sich durch die Finger der beiden Zapfen diese zusammenhaltende Schrauben erstrecken, so dass auch an die Genauigkeit der Parallelbohrungen nur sehr geringe Anforderungen zu stellen sind.However, a particular advantage of the pins according to the invention is that they can be attached to the continuous rung without the use of adhesive. It is possible, for example, to dimension the parallel bores in such a way that the fingers can be pressed into them and fit in them with a clamp fit. According to the invention, however, it is particularly advantageous that the screws holding the two pins extend through the fingers of the two pins, so that the accuracy of the parallel bores also has to be met with very few requirements.

Die Zapfen können aus Kunststoff hergestellt sein, wobei in den Kunststoff eines der Zapfen Schraubenmuttern für die Verbindungsschrauben eingebettet sein können. Gemäss einer bevorzugten Ausführungsform der Erfindung sind die Zapfen als Druckgussteile ausgebildet, wodurch eine ausreichende Masshaltigkeit gewährleistet ist. Diese Druckgussteile sind bevorzugt aus Metall ausgebildet, wobei in einem der Finger eine Durchgangsbohrung zum Durchlass der Verbindungsschraube und in dem anderen Finger eine Gewindebohrung für diese eingebracht sind. Als Metall ist eine Zinklegierung bevorzugt.The pins can be made of plastic, whereby one of the pins can have embedded nuts for the connecting screws in the plastic. According to a preferred embodiment of the invention, the pins are designed as die-cast parts, which ensures sufficient dimensional accuracy. These die-cast parts are preferably made of metal, with a through hole for the passage of the connecting screw in one of the fingers and a threaded hole for the other in the other finger. A zinc alloy is preferred as the metal.

Da einer der Finger eine Gewindebohrung und der andere Finger eine Durchgangsbohrung aufweist, liegt, wenn man zwei gleichartige Zapfen mit ihren Fingern einander gegenüberstellt, jeweils eine Gewindebohrung vor einer Durchgangsbohrung. Es ist somit nur eine einzige Bauform eines Zapfens erforderlich, da beide Zapfen einer Kreuzverbindungsstelle baugleich sind. Hierdurch werden Herstellung, Lagerhaltung und Montage noch weiter und in entscheidendem Masse erleichtert.Since one of the fingers has a threaded hole and the other finger has a through hole, if two fingers of the same type are placed opposite one another with their fingers, there is in each case a threaded hole in front of a through hole. Thus, only a single design of a pin is required, since both pins of a cross connection point are identical in construction. This makes manufacturing, warehousing and assembly even easier and to a significant extent.

Die Zapfen weisen einen solchen Querschnitt auf, dass jene Hohlstäbe, die die querverlaufenden Sprossen bilden, auf die Zapfen aufgeschoben werden können. Hierbei können diese Querstäbe mit den Aussenflächen der Zapfen verklebt werden, wobei die Verschmutzungsgefahr durch Kleber nicht besteht, da die Klebstellen von Sichtkanten weit entfernt sein können.The pins have a cross section such that those hollow bars which form the transverse rungs can be pushed onto the pins. In this case, these cross bars can be glued to the outer surfaces of the pegs, there being no risk of contamination from glue, since the gluing points can be far away from visible edges.

Man kann auch ohne Kleber auskommen, wenn man gemäss einer weiteren Ausgestaltung der Erfindung die Aussenseite des Zapfens mit kantigen Längsrippen versieht, deren vorzugsweise schneidenartig ausgebildete Rücken gegen die Innenoberfläche der Hohlstäbe anliegen. Die Abmessungen der Zapfen sind erfindungsgemäss so auf die Innenabmessungen der Hohlprofilstäbe abgestimmt, dass die Hohlprofilstäbe in jedem Falle auf den Rücken der Längsrippen aufsitzen. Wenn ungünstige Toleranzen zusammenkommen, lassen sich dennoch die Hohlstäbe auf die Zapfen aufschieben, da sich in diesem Falle die scharfkantigen Rücken in das Material der Hohlstäbe eindrücken, die bevorzugt aus aussen mit Kunststoff beschichtetem Aluminium besteht. Somit ist nach dem Zusammensetzen einer Kreuzverbindung keinerlei zusätzliche Halterung oder Einspannung für diese erforderlich, da stets der Zapfen in ausrichtendem und zentrierendem Eingriff mit dem zugeordneten Hohlprofilstab steht.One can also do without glue if, according to a further embodiment of the invention, the outside of the pin is provided with angular longitudinal ribs, the back of which, preferably in the form of a knife, against the Fit the inner surface of the hollow bars. According to the invention, the dimensions of the pins are matched to the internal dimensions of the hollow profile bars in such a way that the hollow profile bars are in any case seated on the back of the longitudinal ribs. If unfavorable tolerances come together, the hollow bars can still be pushed onto the pins, since in this case the sharp-edged backs are pressed into the material of the hollow bars, which preferably consists of aluminum coated with plastic on the outside. Thus, after assembling a cross connection, no additional mounting or clamping is required for this, since the pin is always in aligning and centering engagement with the associated hollow profile rod.

Auch hier ist ein Verkleben möglich.Gluing is also possible here.

Es ist möglich, die Finger so weit zu verlängern, dass die Stirnflächen der beiden an einer Kreuzverbindungsstelle einander gegenüberliegenden Finger aufeinander aufsitzen. Nach dem Verschrauben der beiden betreffenden Zapfen sind diese fest miteinander verbunden, können aber unter Umständen quer zur durchgehenden Sprosse in geringem Masse bewegt werden.It is possible to extend the fingers so far that the end faces of the two fingers lying opposite one another at a cross-connection point sit on one another. After the two relevant pins have been screwed together, they are firmly connected to one another, but can be moved to a small extent transversely to the continuous rung.

Um Spalte zu vermeiden, wird gemäss einer weiteren Ausgestaltung der Erfindung vorgeschlagen, dass die der durchgehenden Sprosse zugewandten Stirnflächen der Zapfen komplementär zu den entsprechenden Seitenflächen der einen Sprosse geformt sind, so dass die Stirnflächen der Zapfen bündig gegen die zugewandte Seitenwand der durchgehenden Sprosse anliegen. In diesem Falle ist die Länge der Finger vorzugsweise derart bemessen, dass deren einander zugewandte Stirnflächen selbst bei ungünstigen Toleranzen nicht aufeinander aufsitzen. Durch Festziehen der Verbindungsschrauben werden somit die beiden Zapfen fest mit der durchgehenden Sprosse verspannt, so dass eine unbewegliche, feste Abstützung für die die querverlaufenden Sprossen bildenden Hohlprofilstäbe gebildet ist.In order to avoid gaps, it is proposed according to a further embodiment of the invention that the end faces of the pins facing the continuous rung are complementary to the corresponding side faces of the one rung, so that the end faces of the pins rest flush against the facing side wall of the continuous rung. In this case, the length of the fingers is preferably dimensioned in such a way that their end faces facing one another do not sit on one another, even with unfavorable tolerances. By tightening the connecting screws, the two pins are thus firmly clamped to the continuous rung, so that an immovable, solid support is formed for the hollow profile bars forming the transverse rungs.

Es ist dem Grunde nach möglich, dass die Durchgangsbohrungen den Zapfen über dessen gesamte Länge durchsetzt und eine entsprechend lange Schraube mit Mutter zum Herstellen der Kreuzverbindung verwendet wird. Da Schrauben der benötigten Länge verhältnismässig teuer sind, wird man danach trachten, diese Schrauben und somit auch den Zapfen möglichst kurz zu halten. Dies aber behindert wiederum die präzise Fixierung der Hohlprofilstäbe beim Zusammenbau.It is basically possible that the through holes penetrate the pin over its entire length and a correspondingly long screw with nut is used to produce the cross connection. Since screws of the required length are relatively expensive, efforts will be made to keep these screws and thus the pin as short as possible. However, this in turn hampers the precise fixing of the hollow profile bars during assembly.

Eine weitere Ausgestaltung der Erfindung besteht darin, dass sich die Durchgangsbohrungen nur durch einen Finger und den angrenzenden Teil des Zapfens erstreckt, über den Rest des Zapfens hinweg aber durch eine Bohrung mit einem so grossen Durchmesser verlängert ist, dass dieser den Knopf der Verbindungsschraube aufzunehmen imstande ist. Es ist somit möglich, die Gesamtlänge des Zapfens unabhängig von jener der Verbindungsschraube so zu wählen, dass eine optimale Fixierung der Hohlprofilstäbe während der Montage erreicht wird.Another embodiment of the invention is that the through holes extend only through a finger and the adjacent part of the pin, but is extended over the rest of the pin through a hole with a diameter so large that it is able to accommodate the button of the connecting screw is. It is thus possible to choose the total length of the pin independently of that of the connecting screw in such a way that the hollow profile rods are optimally fixed during assembly.

Vorteilhafterweise kann auch die Gewindebohrung durch eine vergrösserte Bohrung verlängert sein, was nicht nur die Herstellung des Gewindes vereinfacht, sondern zusammen mit der oben erwähnten, vergrösserten Bohrung dazu beiträgt, dass das den Zapfen bildende Gussstück eine durchgehend verhältnismässig gleichmässige, dünne Wandstärke aufweist, so dass es verzugsfrei hergestellt werden kann. Dies wiederum ermöglicht bei Einhaltung verhältnismässig geringer Toleranzen die Herstellung eines verhältnismässig langen Zapfens und somit eine besonders saubere Führung der Hohlprofilstäbe bei der Herstellung einer Kreuzverbindungsstelle.Advantageously, the threaded bore can also be extended by an enlarged bore, which not only simplifies the production of the thread, but together with the above-mentioned enlarged bore also contributes to the cast piece forming the pin having a consistently uniform, thin wall thickness so that it can be manufactured without warpage. This in turn enables the production of a relatively long pin and thus a particularly clean guidance of the hollow profile bars in the production of a cross connection point if relatively small tolerances are observed.

Das erfindungsgemässe Fenster lässt sich somit mit einfachen Werkstattmitteln einfach, aber sauber und mit hoher Genauigkeit in der Werkstatt herstellen.The window according to the invention can thus be produced simply, but cleanly and with high accuracy in the workshop using simple workshop means.

Es ist schliesslich auch möglich, eine Anzahl erfindungsgemässer Zapfen, Hohlprofilstäbe zur Bildung der Sprossen, eine Bohrschablone zum Einbringen der Parallelbohrungen und eine Schneideschablone zum winkligen Ablängen der querverlaufenden Sprossen als Bausatz zusammenzustellen und zu vertreiben.Finally, it is also possible to assemble and sell a number of pegs according to the invention, hollow profile bars for forming the rungs, a drilling template for making the parallel bores and a cutting template for cutting the transverse rungs to length.

Gegenstand der Erfindung ist nicht nur das Fenster mit Sprossengitter, sondern auch das Sprossengitter allein.The subject of the invention is not only the window with lattice bars, but also the lattice bars alone.

Der Gegenstand der Erfindung ist anhand der beigefügten schematischen Zeichnung beispielsweise noch näher erläutert. In dieser zeigen:

  • Fig. 2 einen Längsschnitt durch einen erfindungsgemässen Zapfen,
  • Fig. 3 die Stirnansicht des Zapfens der Fig. 2 und
  • Fig. 4 die Seitenansicht des Zapfens der Fig. 2.
The object of the invention is explained in more detail with reference to the attached schematic drawing, for example. In this show:
  • 1 is a top view of an already partially assembled cross connection point during its completion,
  • 2 shows a longitudinal section through a pin according to the invention,
  • Fig. 3 is an end view of the pin of Fig. 2 and
  • 4 shows the side view of the pin of FIG. 2.

In Fig. 1 ist die Draufsicht auf eine Kreuzverbindungsstelle eines Fenster-Sprossengitters gezeigt.In Fig. 1, the top view of a cross connection point of a window rung grating is shown.

Die Kreuzverbindungsstelle weist eine durchgehende Sprosse 1 auf, die aus einem aussen mit Kunststoff beschichteten Hohlprofilstab aus Aluminium mit trapezförmigem Querschnitt gebildet ist und zwei Seitenflächen 2 aufweist, welche beiderseits einer (in Fig. 1 verdeckten) Grundfläche angeordnet sind und zu dieser jeweils einen Winkel einschliessen, der kleiner ist als 90°.The cross-connection point has a continuous rung 1, which is formed from an aluminum-coated hollow profile rod made of aluminum with a trapezoidal cross-section and has two side surfaces 2, which are arranged on both sides of a base surface (hidden in FIG. 1) and each form an angle with this that is smaller than 90 °.

In jede der Seitenflächen 2 sind zwei zueinander parallele Parallelbohrungen 3 eingebracht, deren Achsen sich parallel zur genannten Grundfläche sowie senkrecht zur Mittellinie 4 der durchgehenden Sprosse 1 erstrecken.In each of the side surfaces 2, two parallel bores 3 are made, the axes of which extend parallel to the base area mentioned and perpendicular to the center line 4 of the continuous rung 1.

Eine Quersprosse 5 aus einem Hohlprofilstab, welcher die gleichen Abmessungen wie der die durchgehende Sprosse 1 bildende Hohlprofilstab aufweist, erstreckt sich in der gleichen Ebene wie die durchgehende Sprosse 1 und stösst rechtwinklig an diese an (sh. die linke Seite der Fig. 1).A cross rung 5 made of a hollow profile bar, which has the same dimensions as the hollow profile bar forming the continuous rung 1, extends in the same plane as the continuous rung 1 and abuts it at right angles (see the left side of FIG. 1).

Die Quersprosse 5 sitzt auf einem Zapfen 6, dessen Querschnittsprofil zur passenden Aufnahme des die Quersprosse 5 bildenden Hohlprofilstabes ausgebildet ist.The cross bar 5 is seated on a pin 6, the cross-sectional profile of which is designed to accommodate the hollow profile bar forming the cross bar 5.

Der Zapfen 6 ist seinerseits an der zugewandten Seitenfläche 2 der durchgehenden Sprosse 1 befestigt. Hierzu weist er von seiner Stirnfläche 7 (s. Fig. 4) abragende Finger 8 auf, die in die Parallelbohrungen 3 eingeschoben sind.The pin 6 is in turn attached to the facing side surface 2 of the continuous rung 1. For this purpose, it has fingers 8 protruding from its end face 7 (see FIG. 4), which are inserted into the parallel bores 3.

In der linken Seite der Fig. 1 ist ein bereits in die zugehörigen Parallelbohrungen eingeschobener Zapfen 6 gezeigt, auf welchen die Quersprosse 5 bereits aufgeschoben ist. In der rechten Seite der Fig. 1 ist dagegen die Reihenfolge des Zusammenbaus gezeigt: in Richtung des kleinen Pfeiles wird zunächst der Zapfen 6 mit seinen Fingern 8 in die zugewandten Parallelbohrungen 3 eingeschoben, wobei seine Stirnfläche 7 bündig gegen die zugewandte Seitenfläche 2 zur Anlage gelangt. Die beiden Zapfen 6 werden auf eine noch weiter unten beschriebene Weise miteinander verschraubt.In the left side of FIG. 1, a pin 6 is already inserted into the associated parallel bores, on which the cross bar 5 has already been pushed. On the right side of FIG. 1, on the other hand, the order of assembly is shown: in the direction of the small arrow, the pin 6 is first inserted with its fingers 8 into the facing parallel bores 3, its end face 7 coming flush against the facing side face 2 . The two pins 6 are screwed together in a manner described below.

Nachdem die beiden Zapfen 6 aneinander befestigt und kräftig gegen die jeweils zugewandte Seitenfläche 2 der durchgehenden Sprosse 1 angedrückt sind, wird dann auf jeden Zapfen 6 die zugehörige Quersprosse 5 in Richtung des längeren Pfeiles in Fig. 1 aufgeschoben, bis die wie die Stirnfläche 7 schräg abgelängte Stirnfläche des jeweiligen Hohlstabes 5 zur bündigen Anlage gegen die zugewandte Seitenfläche 2 gelangt ist.After the two pins 6 are fastened to one another and pressed firmly against the respectively facing side surface 2 of the continuous rung 1, the associated cross bar 5 is then pushed onto each pin 6 in the direction of the longer arrow in FIG. 1 until it slopes like the end face 7 cut end face of the respective hollow rod 5 has come to rest against the facing side surface 2.

Der Zapfen 6 ist in den Fig. 2 bis 4 im einzelnen dargestellt, und zwar jeweils in doppelter Grösse.The pin 6 is shown in FIGS. 2 to 4 in detail, in each case in double size.

Aus Fig. 3 ist hierbei der trapezförmige Querschnitt des Zapfens 6 ersichtlich, der jenem der Quersprossen 5 ähnlich ist.3 shows the trapezoidal cross section of the pin 6, which is similar to that of the cross bars 5.

Die Neigung der Stirnfläche 7 ist aus Fig. 4 ersichtlich.The inclination of the end face 7 can be seen from FIG. 4.

Die beiden Finger 8 weisen jeweils eine Längsbohrung auf, und zwar weist der eine eine Durchgangsbohrung 9 und der andere eine Gewindebohrung 10 auf. Der Durchmesser der Durchgangsbohrung 9 ist mindestens ebenso gross wie der Nenndurchmesser der Gewindebohrung 10.The two fingers 8 each have a longitudinal bore, namely one has a through bore 9 and the other has a threaded bore 10. The diameter of the through bore 9 is at least as large as the nominal diameter of the threaded bore 10.

Die beiden Bohrungen 9, 10 erstrecken sich, von der Stirnfläche des jeweiligen Fingers 8 ausgehend, zum anderen Ende des Zapfens hin, aber nur über eine verhältnismässig kurze Strecke, die etwa 1/6 der Länge des Zapfens (ohne Finger) entspricht. Dann wird die Durchgangsbohrung 9 von einer erweiterten Bohrung 11 fortgesetzt, während die Gewindebohrung 10 von einer vergrösserten Bohrung 12 fortgesetzt wird. Die Bohrungen 11, 12 münden an dem den Fingern 8 entgegengesetzten Ende des Zapfens 6.The two bores 9, 10 extend from the end face of the respective finger 8 starting, the other end of the pin towards, but only over a relatively short distance, which is about 1/6 corresponding to the length of the pin (without finger). Then the through bore 9 is continued by an enlarged bore 11, while the threaded bore 10 is continued by an enlarged bore 12. The bores 11, 12 open at the end of the pin 6 opposite the fingers 8.

Der Durchmesser der Bohrung 11 ist derart bestimmt, dass er den Kopf einer Verbindungsschraube 13 aufnehmen kann, deren Schaft die Durchgangsbohrung 9 durchsetzt und deren Gewindeteil (nicht gezeigt) in die Gewindebohrung 10 einschraubbar ist.The diameter of the bore 11 is determined in such a way that it can receive the head of a connecting screw 13, the shaft of which passes through the through bore 9 and the threaded part (not shown) of which can be screwed into the threaded bore 10.

Nun ist auch ersichtlich, auf welche Weise die beiden Zapfen 6 mit der durchgehenden Sprosse 1 befestigt sind: bei jedem der beiden Zapfen 6 wird eine Verbindungsschraube 13, das Gewinde voran, in die Bohrung 11 und mit ihrem Schaft in die Durchgangsbohrung 9 eingeführt. Da die beiden zu einer Kreuzverbindungsstelle verwendeten Zapfen 6 baugleich sind, liegt nun jeder Durchgangsbohrung 9 jeweils die Gewindebohrung 10 des anderen Zapfens 6 gegenüber, in welche dann die jeweilige Verbindungsschraube 13 solange eingeschraubt wird, bis sie mit der Sitzfläche ihres Kopfes gegen die Gegensitzfläche zur Anlage gelangt, die beim Übergang zwischen der jeweiligen Bohrung 11 und der jeweiligen Durchgangsbohrung 9 gebildet ist. Hierbei haben die Stirnenden der jeweiligen Finger 8 der beiden Zapfen 6 noch einen gegenseitigen Abstand, so dass durch weiteres Festziehen der Schraube 13 die Stirnfläche 7 der beiden Zapfen 6 fest gegen die zugewandte Seitenfläche 2 der durchgehenden Sprosse 1 angepresst wird.Now it can also be seen how the two pins 6 are fastened with the continuous rung 1: in each of the two pins 6, a connecting screw 13, the thread first, is inserted into the bore 11 and with its shaft into the through bore 9. Since the two pins 6 used for a cross connection point are identical, each through hole 9 is now opposite the threaded hole 10 of the other pin 6, into which the respective connecting screw 13 is then screwed in until it rests with the seat of its head against the opposite seat surface arrives, which is formed at the transition between the respective bore 11 and the respective through bore 9. Here, the ends of the respective fingers 8 of the two pins 6 are still at a mutual distance, so that by further tightening the screw 13, the end face 7 of the two pins 6 is pressed firmly against the facing side surface 2 of the continuous rung 1.

Wie aus den Fig. 2 bis 4 ersichtlich, weist der Zapfen 6 sich über seine gesamte Länge erstreckende Längsrippen 13 auf, von denen jede den Querschnitt eines gleichschenkligen, rechteckigen Dreiecks aufweist, dessen Basis gegen die zugewandte Aussenoberfläche des Zapfens 6 anliegt.As can be seen from FIGS. 2 to 4, the pin 6 has longitudinal ribs 13 extending over its entire length, each of which has the cross section of an isosceles, rectangular triangle, the base of which rests against the facing outer surface of the pin 6.

Wie aus der Fig. 3 ersichtlich, verläuft jeweils eine Längsrippe 13 nahe jedem der Ränder der beiden zueinander parallelen Aussenflächen des Zapfens 6, während in der Mitte einer jeden der beiden zueinander geneigten Seitenflächen des Zapfens 6 jeweils eine weitere Längsrippe angeordnet ist.As can be seen from FIG. 3, a longitudinal rib 13 runs near each of the edges of the two mutually parallel outer surfaces of the pin 6, while a further longitudinal rib is arranged in the middle of each of the two mutually inclined side surfaces of the pin 6.

Das von den Fingern 8 abgewandte Ende des Zapfens 6 ist an seinen Kanten abgeschrägt, um ein leichteres Aufschieben der zugehörigen Quersprosse zu ermöglichen.The end of the pin 6 facing away from the fingers 8 is chamfered at its edges in order to enable the associated cross rung to be pushed open more easily.
