Definitions

  • the invention relates to a connecting device for the mutual fixing of transoms and posts of plastic windows, which are formed from plastic hollow profile parts, each with inserted metal profile part.
  • a similar connection device is provided in a T-connection of transoms and posts in plastic windows known from DE-A-33 06 426.
  • the metal profile part and the plastic hollow profile part of the post are provided with a continuous transverse bore into which a bolt with a threaded bore perpendicular to the axis of the bolt is inserted.
  • a clamping screw can be screwed into this bolt, which is screwed from the outside through the bolt of the plastic window into the threaded hole of the bolt.
  • the bolt is provided with a screw slot so that the bolt rotates accordingly and so that the threaded hole in the bolt can be aligned with the axis of the clamping screw.
  • the bolt is secured in its position by a connecting screw which fulfills the function of a lock nut and which is screwed into the bolt from one side of the post through its plastic hollow profile part.
  • a head of the bolt on the one hand and the head of this connecting screw on the other are each on the outside of the plastic hollow profile part of the post, which often has a disadvantageous effect especially when installing hinges or other fittings in plastic windows. There are then no flat stop surfaces for such fitting parts in this area.
  • it is a multi-part bolt, which is also unsuitable for mass production for manufacturing reasons, in particular because two internal threads are in the bolt are provided and because a corresponding connecting screw must also be provided as a kind of lock nut in order to be able to secure the bolt in its position.
  • the known T-connection at one post end cannot be produced independently of an identical T-connection at the other post end.
  • the metal profile part extends essentially continuously over the length of the post and receives the bolt of another connecting element at its other end. If the T-connection at one post end with a certain clamping force has been made by tightening the clamping screw, this clamping force is partially canceled when the T-connection is made at the opposite post end, because the bolt also extends through the plastic hollow profile part and the metal profile part and the power flow goes from one clamping screw over the plastic hollow profile part and the metal profile part to the other clamping screw.
  • the known T-connection it is therefore not possible to fix the post individually at one end to a transom and independently of a further T-connection made on the same post. It is particularly disadvantageous that the known T-connection can only be made at one end between the mullion and transom if there is a corresponding T-connection or another counter-holder for the clamping force exerted at the other end.
  • the object of the invention is to design a connecting device of the type mentioned at the outset in such a way that transoms and posts can be mutually fixed with an individual and independent of a further connecting device or the like acting on the same post.
  • the connecting device according to the invention has the advantage that the plastic hollow profile parts do not need to have a transverse bore for receiving the bolt, since this extends only through the metal profile part, which is inserted into the plastic profile part with the preassembled bolt. At most, the fastening device for the mutual transmission of force between the plastic hollow profile part and the metal profile part of the post still requires cross bores, but these are easier to manufacture, much smaller and therefore less noticeable than the large cross bore required for the bolt in the prior art.
  • the connection between the plastic hollow profile part and the metal profile part of the post takes place only via the fastening device, ie not via the bolt. Therefore, in the connecting device according to the invention, the force flow between the plastic hollow profile part and the metal profile part of the post is via the fastening device provided for their mutual fastening and for the transmission of force between them.
  • the clamping screw of the connecting element of the connecting device according to the invention provided at one end of the post, for the clamping force for mutually fixing the transom and post individually and independently of a further connecting device or the like acting on the same post To be able to adjust the counter-holding device.
  • the clamping force once set on one post end is essentially no longer changed by attaching a further connecting device on the other post end. Therefore, it is also possible to set different clamping forces with both connecting devices. This would not be possible if, as in the prior art, the bolt would extend through the plastic hollow profile part and the metal profile part, since then the tension force, i.e. the contact pressure between the post and the transom, would be the same at both post ends, i.e. could not be set differently because the power flow would only go through the bolt.
  • the tensioning or contact pressure can be adjusted differently at both post ends, since the transmission of the power flow from the tensioning screw to the Plastic hollow profile part of the post does not go over the bolt, but via the fastening device which is provided for the mutual transmission of force between the plastic hollow profile part and the metal profile part of the post.
  • the metal profile part is a short piece that only extends in the area of the connection between a transom and a post, then different clamping or contact forces on both post ends can be adjusted even better independently of one another, since only that in each Short metal profile piece provided post end area via the connecting screws for power transmission to the plastic hollow profile part, in order to be able to clamp the post with the transom at each post end.
  • This embodiment of the connecting device according to the invention results in the simplest way because the passage of the bolt through the plastic hollow profile part of the post, which is necessary in the prior art, with the associated disadvantages is avoided, and at the same time a fastening device, which would otherwise only have been used for the mutual fixation of the plastic hollow profile part and the metal profile part of the post, is used for the mutual transmission of force between these two profile parts of the post.
  • the fastening device consists of one or more screws, in particular self-tapping self-drilling screws, which extend parallel to the bolt through the plastic hollow profile part and the metal profile part.
  • These screws are used for the pre-assembly of the plastic hollow profile part and the metal profile part of the post for their mutual position fixing and from the time of screwing the clamping screw into the threaded hole of the bolt, from which their position fixing function becomes unnecessary when the metal profile part extends over the post length, for mutual force transmission between the plastic hollow profile part and Metal profile part of the post.
  • small screws are sufficient, the assembly of which requires considerably less effort than is the case in the prior art, where a transverse bore through the plastic hollow profile part and the metal profile part has to be made for receiving the bolt.
  • the fit between the transverse bore in the metal profile part of the post and the bolt is expediently chosen as a tight fit, so that the bolt maintains its once selected position with a threaded bore oriented in the direction of the longitudinal axis of the clamping screw to be screwed in.
  • This retention of the once selected orientation of the bolt can instead or additionally be secured in that in a further embodiment of the invention the bolt is provided with fine toothing at one end in order to secure the bolt until it is finally connected by the tensioning screw and secured against axial displacement hold.
  • the bolt can be inserted so far that it already engages with its other end in the through hole of the opposite wall of the metal hollow profile part.
  • a short impact movement on the bolt penetrates the fine toothing into the wall of the through hole and thus creates a secure connection between the bolt and the metal hollow profile part.
  • Such a configuration makes it even safer not to provide a head on the bolt.
  • This bolt can therefore be hidden even more securely in the case of plastic windows in the plastic hollow profile part of the post, and there are no parts of the bolt which obstruct the fitting of fittings on the outside of the plastic hollow profile part.
  • the production of the bolt used in the connecting device according to the invention is very simple and inexpensive, especially since the production can be carried out in a cold pressing process, the threaded bore and the fine toothing then being formed in further working processes, which e.g. can be done in a simple rolling process.
  • the bolt has on one end face parallel to the axis of the threaded bore in the bolt or rotated by 90 ° to the marking recesses and / or elevations. This makes it possible for the bolt to be precisely aligned before it is finally driven in, so that the threaded bore in the bolt is also arranged in exact alignment with the clamping screw to be inserted.
  • marking recesses are also part of the prior art mentioned at the outset, but with the known T-connection it is always possible to turn the bolt later.

Description

Die Erfindung betrifft eine Verbindungsvorrichtung zur gegenseitigen Fixierung von Riegel und Pfosten von Kunststoff-Fenstern, welche aus Kunststoffhohlprofilteilen mit jeweils eingeschobenem Metallprofilteil gebildet sind.The invention relates to a connecting device for the mutual fixing of transoms and posts of plastic windows, which are formed from plastic hollow profile parts, each with inserted metal profile part.

Eine ähnliche Verbindungsvorrichtung ist bei einer aus der DE-A-33 06 426 bekannten T-Verbindung von Riegel und Pfosten in Kunststoff-Fenstern vorgesehen. Bei dieser bekannten T-Verbindung sind das Metallprofilteil und das Kunststoffhohlprofilteil des Pfostens mit einer durchgehenden Querbohrung versehen, in welche ein Bolzen mit einer senkrecht zur Achse des Bolzens stehenden Gewindebohrung eingesetzt wird. In diesen Bolzen kann eine Spannschraube eingeschraubt werden, welche von außen durch den Riegel des Kunststoff-Fensters hindurch in die Gewindebohrung des Bolzens eingeschraubt wird. Der Bolzen ist mit einem Schraubschlitz versehen, damit der Bolzen entsprechend verdreht und so die Gewindebohrung im Bolzen mit der Achse der Spannschraube ausgerichtet werden kann. Der Bolzen wird durch eine die Funktion einer Gegenmutter erfüllenden Verbindungsschraube, welche von einer Seite des Pfostens aus durch dessen Kunststoffhohlprofilteil hindurch in den Bolzen eingedreht wird, in seiner Lage gesichert. Ein Kopf des Bolzens einerseits und der Kopf dieser Verbindungsschraube andererseits liegen jeweils an der Außenseite des Kunststoffhohlprofilteils des Pfostens an, was sich oft gerade bei der Montage von Scharnieren oder sonstigen Beschlagteilen bei Kunststoff-Fenstern nachteilig auswirkt. Es sind dann in diesem Bereich keine ebenen Anschlagflächen für solche Beschlagteile vorhanden. Außerdem handelt es sich um einen mehrteiligen Bolzen, welcher auch aus Herstellungsgründen für die Massenfertigung ungeeignet ist, insbesondere auch deshalb, weil im Bolzen zwei Innengewinde vorgesehen sind und weil auch eine entsprechende Verbindungsschraube als eine Art Gegenmutter vorgesehen werden muß, um den Bolzen in seiner Lage sichern zu können. Selbst wenn der Kopf des Bolzens und der Kopf der Verbindungsschraube im Kunststoffhohlprofilteil versenkbar ausgebildet würden, müßte trotzdem die durch das Kunststoffhohlprofilteil und durch das Metallprofilteil des Pfostens durchgehende Querbohrung vorgesehen werden, da die bekannte T-Verbindung erfordert, daß sich der Bolzen zur Kraftübertragung von der Spannschraube aus sowohl durch das Kunststoffhohlprofilteil als auch durch das Metallprofilteil des Pfostens erstreckt. Einerseits führt das zu einer weiteren Erschwerung der Montage, da diese Querbohrung an Ort und Stelle bei bereits eingesetztem Metallprofilteil hergestellt wird oder, wenn diese Querbohrung im Kunststoffhohlprofilteil und im Metallprofilteil bereits vorhanden ist, die beiden letzteren genau aufeinander ausgerichtet werden müssen, damit der Bolzen von außen eingeführt werden kann. Andererseits ist die bekannte T-Verbindung an einem Pfostenende nicht unabhängig von einer gleichen T-Verbindung am anderen Pfostenende herstellbar. Üblicherweise erstreckt sich nämlich das Metallprofilteil im wesentlichen durchgehend über die Länge des Pfostens und nimmt an seinem anderen Ende den Bolzen eines weiteren Verbindungselements auf. Wenn die T-Verbindung am einen Pfostenende mit bestimmter Spannkraft durch Anziehen der Spannschraube hergestellt worden ist, so wird diese Spannkraft beim Herstellen der T-Verbindung am entgegengesetzten Pfostenende teilweise wieder aufgehoben, weil sich der Bolzen auch dort durch das Kunststoffhohlprofilteil und das Metallprofilteil erstreckt und der Kraftfluß von der einen Spannschraube über das Kunststoffhohlprofilteil und das Metallprofilteil zur anderen Spannschraube geht. Bei der bekannten T-Verbindung ist es daher nicht möglich, den Pfosten an einem Ende an einem Riegel individuell und unabhängig von einer an demselben Pfosten hergestellten weiteren T-Verbindung fixieren zu können. Besonders nachteilig ist, daß die bekannte T-Verbindung überhaupt nur einenends zwischen Pfosten und Riegel hergestellt werden kann, wenn anderenends eine entsprechende T-Verbindung oder ein anderer Gegenhalter für die einenends ausgeübte Spannkraft vorhanden ist.A similar connection device is provided in a T-connection of transoms and posts in plastic windows known from DE-A-33 06 426. In this known T-connection, the metal profile part and the plastic hollow profile part of the post are provided with a continuous transverse bore into which a bolt with a threaded bore perpendicular to the axis of the bolt is inserted. A clamping screw can be screwed into this bolt, which is screwed from the outside through the bolt of the plastic window into the threaded hole of the bolt. The bolt is provided with a screw slot so that the bolt rotates accordingly and so that the threaded hole in the bolt can be aligned with the axis of the clamping screw. The bolt is secured in its position by a connecting screw which fulfills the function of a lock nut and which is screwed into the bolt from one side of the post through its plastic hollow profile part. A head of the bolt on the one hand and the head of this connecting screw on the other are each on the outside of the plastic hollow profile part of the post, which often has a disadvantageous effect especially when installing hinges or other fittings in plastic windows. There are then no flat stop surfaces for such fitting parts in this area. In addition, it is a multi-part bolt, which is also unsuitable for mass production for manufacturing reasons, in particular because two internal threads are in the bolt are provided and because a corresponding connecting screw must also be provided as a kind of lock nut in order to be able to secure the bolt in its position. Even if the head of the bolt and the head of the connecting screw were designed to be retractable in the plastic hollow profile part, the transverse bore through the plastic hollow profile part and through the metal profile part of the post would still have to be provided, since the known T-connection requires that the bolt for power transmission from the Tensioning screw extends from both the plastic hollow profile part and the metal profile part of the post. On the one hand, this leads to a further complication of the assembly, since this transverse bore is made on the spot with a metal profile part already inserted or, if this transverse bore is already present in the plastic hollow profile part and in the metal profile part, the latter two must be aligned precisely with one another so that the bolt of can be introduced outside. On the other hand, the known T-connection at one post end cannot be produced independently of an identical T-connection at the other post end. Usually, the metal profile part extends essentially continuously over the length of the post and receives the bolt of another connecting element at its other end. If the T-connection at one post end with a certain clamping force has been made by tightening the clamping screw, this clamping force is partially canceled when the T-connection is made at the opposite post end, because the bolt also extends through the plastic hollow profile part and the metal profile part and the power flow goes from one clamping screw over the plastic hollow profile part and the metal profile part to the other clamping screw. With the known T-connection it is therefore not possible to fix the post individually at one end to a transom and independently of a further T-connection made on the same post. It is particularly disadvantageous that the known T-connection can only be made at one end between the mullion and transom if there is a corresponding T-connection or another counter-holder for the clamping force exerted at the other end.

Aufgabe der Erfindung ist es, eine Verbindungsvorrichtung der eingangs genannten Art so auszubilden, daß sich Riegel und Pfosten mit einer individuell und unabhängig von einer an demselben Pfosten angreifenden weiteren Verbindungsvorrichtung oder dergleichen gegenseitig fixieren lassen.The object of the invention is to design a connecting device of the type mentioned at the outset in such a way that transoms and posts can be mutually fixed with an individual and independent of a further connecting device or the like acting on the same post.

Zur Lösung dieser Aufgabe besteht die Verbindungsvorrichtung zur gegenseitigen Fixierung von Riegel und Pfosten von Kunststoff-Fenstern, welche aus Kunststoffhohlprofilteilen mit jeweils eingeschobenem Metallprofilteil gebildet sind, aus

  • · einem Verbindungselement, das einen Bolzen und eine Spannschraube aufweist, wobei der Bolzen eine Länge hat, die im wesentlichen der Dicke des Metallprofilteils des Pfostens entspricht und die lichte Weite des Kunststoffhohlprofilteils des Pfostens nicht übersteigt, und mit einer quer zu seiner Längsachse ausgerichteten Gewindebohrung versehen ist, in die die Spannschraube von außen durch den Riegel in die Gewindebohrung einschraubbar ist,
  • · einer durch das Metallprofilteil des Pfostens an einem Ende desselben durchgehenden Querbohrung, die den Bolzen mit Festsitz aufnimmt und
  • · einer Befestigungseinrichtung zur gegenseitigen Fixierung von Kunststoffhohlprofilteil und Metallprofilteil des Pfostens.
To achieve this object, the connecting device for mutually fixing the transom and mullion of plastic windows, which are formed from plastic hollow profile parts, each with inserted metal profile part, consists of
  • A connecting element which has a bolt and a tensioning screw, the bolt having a length which essentially corresponds to the thickness of the metal profile part of the post and does not exceed the inside width of the plastic hollow profile part of the post, and is provided with a threaded bore oriented transversely to its longitudinal axis into which the clamping screw can be screwed from the outside through the bolt into the threaded hole,
  • · A through hole through the metal profile part of the post at one end of the same, which receives the bolt with a tight fit and
  • · A fastening device for the mutual fixing of plastic hollow profile part and metal profile part of the post.

Die Verbindungsvorrichtung nach der Erfindung bringt den Vorteil mit sich, daß die Kunststoffhohlprofilteile keine Querbohrung zur Aufnahme des Bolzens aufzuweisen brauchen, da sich dieser nur noch durch das Metallprofilteil, das mit lagerichtig vormontiertem Bolzen in das Kunststoffprofilteil eingeschoben wird, erstreckt. Allenfalls die Befestigungseinrichtung zur gegenseitigen Kraftübertragung zwischen Kunststoffhohlprofilteil und Metallprofilteil des Pfostens erfordert noch Querbohrungen, die aber leichter herstellbar, wesentlich kleiner und daher unauffälliger als die im Stand der Technik erforderliche große Querbohrung für den Bolzen sind.The connecting device according to the invention has the advantage that the plastic hollow profile parts do not need to have a transverse bore for receiving the bolt, since this extends only through the metal profile part, which is inserted into the plastic profile part with the preassembled bolt. At most, the fastening device for the mutual transmission of force between the plastic hollow profile part and the metal profile part of the post still requires cross bores, but these are easier to manufacture, much smaller and therefore less noticeable than the large cross bore required for the bolt in the prior art.

Darüber hinaus erfolgt bei der Verbindungsvorrichtung nach der Erfindung die Verbindung zwischen Kunststoffhohlprofilteil und Metallprofilteil des Pfostens lediglich über die Befestigungseinrichtung, also nicht über den Bolzen. Deshalb geht bei der Verbindungsvorrichtung nach der Erfindung der Kraftfluß zwischen dem Kunststoffhohlprofilteil und dem Metallprofilteil des Pfostens über die zu deren gegenseitiger Befestigung und zur Kraftübertragung zwischen denselben vorgesehene Befestigungseinrichtung. Das ermöglicht, mit der Spannschraube des Verbindungselements der an einem Ende des Pfostens vorgesehenen Verbindungsvorrichtung nach der Erfindung die Spannkraft zur gegenseitigen Fixierung von Riegel und Pfosten individuell und unabhängig von einer an demselben Pfosten angreifenden weiteren Verbindungsvorrichtung oder dergleichen Gegenhalteeinrichtung einstellen zu können. Da Kunststoffhohlprofilteil und Metallprofilteil des Pfostens durch die Befestigungseinrichtung gegenseitig fixiert sind, wird die am einen Pfostenende einmal eingestellte Spannkraft durch das Anbringen einer weiteren Verbindungsvorrichtung am anderen Pfostenende im wesentlichen nicht mehr verändert. Daher ist es auch möglich, mit beiden Verbindungsvorrichtungen unterschiedliche Spannkräfte einzustellen. Das wäre nicht möglich, wenn sich, wie im Stand der Technik, der Bolzen durch Kunststoffhohlprofilteil und Metallprofilteil erstrecken würde, da dann an beiden Pfostenenden die Spannkraft, d.h. die Anpreßkraft zwischen Pfosten und Riegel, gleich wäre, also nicht unterschiedlich eingestellt werden könnte, weil der Kraftfluß nur über den Bolzen ginge. Wenn bei der bekannten T-Verbindung Verbindungsschrauben zwischen Kunststoffhohlprofilteil und Metallprofilteil des Pfostens vorgesehen würden, die in der DE-A-33 06 426 allerdings nicht erwähnt sind, um diese beiden Profilteile des Pfostens bis zum Einsetzen des Bolzens gegenseitig zu fixieren, so würde auch in diesem Fall der Kraftfluß hauptsächlich über den Bolzen gehen, und die Verbindungsschrauben würden keine Kraftübertragungsfunktion erfüllen.In addition, in the connecting device according to the invention, the connection between the plastic hollow profile part and the metal profile part of the post takes place only via the fastening device, ie not via the bolt. Therefore, in the connecting device according to the invention, the force flow between the plastic hollow profile part and the metal profile part of the post is via the fastening device provided for their mutual fastening and for the transmission of force between them. This makes it possible, with the clamping screw of the connecting element of the connecting device according to the invention provided at one end of the post, for the clamping force for mutually fixing the transom and post individually and independently of a further connecting device or the like acting on the same post To be able to adjust the counter-holding device. Since the plastic hollow profile part and the metal profile part of the post are mutually fixed by the fastening device, the clamping force once set on one post end is essentially no longer changed by attaching a further connecting device on the other post end. Therefore, it is also possible to set different clamping forces with both connecting devices. This would not be possible if, as in the prior art, the bolt would extend through the plastic hollow profile part and the metal profile part, since then the tension force, i.e. the contact pressure between the post and the transom, would be the same at both post ends, i.e. could not be set differently because the power flow would only go through the bolt. If connecting screws were provided between the plastic hollow profile part and the metal profile part of the post in the known T-connection, which are not mentioned in DE-A-33 06 426, however, in order to fix these two profile parts of the post to each other until the bolt was inserted, it would also in this case, the power flow is mainly through the bolt, and the connecting screws would not perform a power transmission function.

Vorteilhafte Ausgestaltungen der Erfindung bilden die Gegenstände der Unteransprüche.Advantageous embodiments of the invention form the subject of the subclaims.

Wenn sich das Metallprofilteil im wesentlichen durchgehend über die Länge des Pfostens erstreckt und vorzugsweise an seinem anderen Ende den Bolzen eines weiteren Verbindungselements aufnimmt, so läßt sich die Spann- oder Anpreßkraft an beiden Pfostenenden unterschiedlich einstellen, da die Übertragung des Kraftflusses von der Spannschraube auf das Kunststoffhohlprofilteil des Pfostens nicht über den Bolzen geht, sondern über die Befestigungseinrichtung, die zur gegenseitigen Kraftübertragung zwischen Kunststoffhohlprofilteil und Metallprofilteil des Pfostens vorgesehen ist.If the metal profile part extends substantially continuously over the length of the post and preferably receives the bolt of a further connecting element at its other end, the tensioning or contact pressure can be adjusted differently at both post ends, since the transmission of the power flow from the tensioning screw to the Plastic hollow profile part of the post does not go over the bolt, but via the fastening device which is provided for the mutual transmission of force between the plastic hollow profile part and the metal profile part of the post.

Wenn in weiterer Ausgestaltung der Erfindung das Metallprofilteil ein kurzes Stück ist, das sich nur im Bereich der Verbindung zwischen einem Riegel und einem Pfosten erstreckt, so lassen sich unterschiedliche Spann- oder Anpreßkräfte an beiden Pfostenenden noch besser unabhängig voneinander einstellen, da nur das in jedem Pfostenendbereich vorgesehene kurze Metallprofilstück über die Verbindungsschrauben zur Kraftübertragung auf das Kunststoffhohlprofilteil dient, um an jedem Pfostenende den Pfosten mit dem Riegel verspannen zu können. Diese Ausgestaltung der erfindungsgemäßen Verbindungsvorrichtung ergibt sich auf einfachste Weise, weil die im Stand der Technik erforderliche Hindurchführung des Bolzens durch das Kunststoffhohlprofilteil des Pfostens mit den damit verbundenen Nachteilen vermieden und gleichzeitig eine Befestigungseinrichtung, die sonst nur zur gegenseitigen Fixierung von Kunststoffhohlprofilteil und Metallprofilteil des Pfostens gedient hätte, zur gegenseitigen Kraftübertragung zwischen diesen beiden Profilteilen des Pfostens ausgenutzt wird.If, in a further embodiment of the invention, the metal profile part is a short piece that only extends in the area of the connection between a transom and a post, then different clamping or contact forces on both post ends can be adjusted even better independently of one another, since only that in each Short metal profile piece provided post end area via the connecting screws for power transmission to the plastic hollow profile part, in order to be able to clamp the post with the transom at each post end. This embodiment of the connecting device according to the invention results in the simplest way because the passage of the bolt through the plastic hollow profile part of the post, which is necessary in the prior art, with the associated disadvantages is avoided, and at the same time a fastening device, which would otherwise only have been used for the mutual fixation of the plastic hollow profile part and the metal profile part of the post, is used for the mutual transmission of force between these two profile parts of the post.

Besonders einfach läßt sich die Ausgestaltung der Verbindungsvorrichtung nach der Erfindung realisieren, bei der die Befestigungseinrichtung aus einer oder mehreren Schrauben, insbesondere aus sich ihr Gewinde selbst schneidenden Bohrschrauben, besteht, die sich parallel zum Bolzen durch das Kunststoffhohlprofilteil und das Metallprofilteil erstrecken. Diese Schrauben dienen bei der Vormontage von Kunststoffhohlprofilteil und Metallprofilteil des Pfostens zu deren gegenseitiger Lagefixierung und ab dem Zeitpunkt des Einschraubens der Spannschraube in die Gewindebohrung des Bolzens, ab welchem ihre Lagefixierfunktion bei sich über die Pfostenlänge erstreckendem Metallprofilteil überflüssig wird, zur gegenseitigen Kraftübertragung zwischen Kunststoffhohlprofilteil und Metallprofilteil des Pfostens. Dafür sind kleine Schrauben ausreichend, deren Montage wesentlich weniger Aufwand erfordert als es im Stand der Technik der Fall ist, wo eine durch das Kunststoffhohlprofilteil und das Metallprofilteil durchgehende Querbohrung zur Aufnahme des Bolzens hergestellt werden muß.The design of the connecting device according to the invention can be realized particularly easily, in which the fastening device consists of one or more screws, in particular self-tapping self-drilling screws, which extend parallel to the bolt through the plastic hollow profile part and the metal profile part. These screws are used for the pre-assembly of the plastic hollow profile part and the metal profile part of the post for their mutual position fixing and from the time of screwing the clamping screw into the threaded hole of the bolt, from which their position fixing function becomes unnecessary when the metal profile part extends over the post length, for mutual force transmission between the plastic hollow profile part and Metal profile part of the post. For this purpose, small screws are sufficient, the assembly of which requires considerably less effort than is the case in the prior art, where a transverse bore through the plastic hollow profile part and the metal profile part has to be made for receiving the bolt.

Bei der Verbindungsvorrichtung nach der Erfindung wird die Passung zwischen der Querbohrung im Metallprofilteil des Pfostens und dem Bolzen zweckmäßig als Festsitz gewählt, so daß der Bolzen seine einmal gewählte Lage mit in Richtung auf die Längsachse der einzuschraubenden Spannschraube ausgerichteter Gewindebohrung beibehält. Diese Beibehaltung der einmal gewählten Ausrichtung des Bolzens läßt sich stattdessen oder zusätzlich dadurch sichern, daß in weiterer Ausgestaltung der Erfindung der Bolzen an einem Ende mit einer Feinverzahnung versehen wird, um den Bolzen bis zum endgültigen Verbinden durch die Spannschraube verdrehsicher und gegen axiales Verschieben gesichert zu halten. Wenn also die Durchgangsbohrung im Metallprofilteil annähernd der Außenabmessung des Bolzens entspricht und es sich beim Metallprofilteil um ein Hohlprofilteil handelt, so kann der Bolzen so weit eingeführt werden, daß er auch mit seinem anderen Ende bereits in die Durchgangsbohrung der gegenüberliegenden Wand des Metallhohlprofilteils eingreift. Durch eine kurze Schlagbewegung auf den Bolzen dringt die Feinverzahnung in die Wandung der Durchgangsbohrung ein und bewirkt so eine sichere Verbindung zwischen dem Bolzen und dem Metallhohlprofilteil. Es ist so auch möglich, den Bolzen kurz vor dem endgültigen Einsetzen in das Metallprofilteil so auszurichten, daß die im Bolzen vorgesehene Gewindebohrung in der richtigen Lage ist, worauf dann die endgültige Lage des Bolzens mit einem nur kurzen Schlag fixiert werden kann.In the connecting device according to the invention, the fit between the transverse bore in the metal profile part of the post and the bolt is expediently chosen as a tight fit, so that the bolt maintains its once selected position with a threaded bore oriented in the direction of the longitudinal axis of the clamping screw to be screwed in. This retention of the once selected orientation of the bolt can instead or additionally be secured in that in a further embodiment of the invention the bolt is provided with fine toothing at one end in order to secure the bolt until it is finally connected by the tensioning screw and secured against axial displacement hold. So if the through hole in the metal profile part approximately corresponds to the outer dimension of the bolt and the metal profile part is a hollow profile part, the bolt can be inserted so far that it already engages with its other end in the through hole of the opposite wall of the metal hollow profile part. A short impact movement on the bolt penetrates the fine toothing into the wall of the through hole and thus creates a secure connection between the bolt and the metal hollow profile part. It is also possible to align the bolt shortly before it is finally inserted into the metal profile part so that the threaded hole provided in the bolt is in the correct position, whereupon the final position of the bolt can be fixed with a short stroke.

Durch eine solche Ausgestaltung ist es noch sicherer möglich, am Bolzen keinen Kopf vorzusehen. Dieser Bolzen kann daher noch sicherer bei Kunststoff-Fenstern verborgen im Kunststoffhohlprofilteil des Pfostens angeordnet werden, und es sind an der Außenseite des Kunststoffhohlprofilteils keine die Montage von Beschlägen behindernden Teile des Bolzens vorhanden. Die Herstellung des bei der Verbindungsvorrichtung nach der Erfindung eingesetzten Bolzens ist an sich sehr einfach und kostengünstig, zumal die Herstellung in einem Kaltpreßverfahren erfolgen kann, wobei in weiteren Arbeitsverfahren dann noch die Gewindebohrung und die Feinverzahnung ausgebildet werden, was z.B. in einem einfachen Walzverfahren erfolgen kann.Such a configuration makes it even safer not to provide a head on the bolt. This bolt can therefore be hidden even more securely in the case of plastic windows in the plastic hollow profile part of the post, and there are no parts of the bolt which obstruct the fitting of fittings on the outside of the plastic hollow profile part. The production of the bolt used in the connecting device according to the invention is very simple and inexpensive, especially since the production can be carried out in a cold pressing process, the threaded bore and the fine toothing then being formed in further working processes, which e.g. can be done in a simple rolling process.

Eine weitere vorteilhafte Maßnahme liegt darin, daß der Bolzen an einer Stirnseite parallel zur Achse der Gewindebohrung im Bolzen oder um 90° verdreht zu dieser ausgerichtete Markierungsvertiefungen und/oder -erhebungen aufweist. Dadurch ist es möglich, daß der Bolzen vor dem endgültigen Einschlagen exakt ausgerichtet werden kann, damit auch die Gewindebohrung im Bolzen in exakter Ausrichtung zur einzusetzenden Spannschraube angeordnet ist. Solche Markierungsvertiefungen gehören wohl auch zum eingangs erwähnten Stand der Technik, doch ist bei der bekannten T-Verbindung stets auch nachträglich noch ein Verdrehen des Bolzens möglich. Wenn jedoch eine nachträgliche Verdrehung durch das Eingreifen der Feinverzahnung in die Bohrungswand nicht mehr möglich ist, bedarf es einer exakten Voreinstellung der Drehlage des Bolzens, bevor dieser endgültig in die Durchgangsbohrung des Metallprofilteils eingeschlagen wird.Another advantageous measure is that the bolt has on one end face parallel to the axis of the threaded bore in the bolt or rotated by 90 ° to the marking recesses and / or elevations. This makes it possible for the bolt to be precisely aligned before it is finally driven in, so that the threaded bore in the bolt is also arranged in exact alignment with the clamping screw to be inserted. Such marking recesses are also part of the prior art mentioned at the outset, but with the known T-connection it is always possible to turn the bolt later. If, however, subsequent twisting is no longer possible due to the fine toothing engaging in the bore wall, the exact rotational position of the bolt is required before it is finally driven into the through bore of the metal profile part.

In diesem Zusammenhang ist es auch vorteilhaft, wenn der Bolzen an einer Stirnseite mit einem Innen- oder Außenangriff für ein Drehwerkzeug ausgeführt ist. Die entsprechende Lage des Bolzens kann so in einfacher Weise eingestellt werden, woraufhin der Bolzen dann durch einen kurzen Schlag in die endgültige Stellung gebracht werden kann.In this context, it is also advantageous if the bolt is designed on one end face with an internal or external attack for a turning tool. The corresponding position of the bolt can thus be set in a simple manner, whereupon the bolt can then be brought into the final position by a short blow.

In noch weiterer Ausgestaltung der Erfindung ist es vorteilhaft, wenn der Bolzen zur Zentrierung beim Einführen des Bolzens in das Metallprofilteil an wenigstens einer Stirnseite mit einer kegelförmigen Vertiefung versehen ist.In yet another embodiment of the invention, it is advantageous if the bolt for centering is provided with a conical depression on at least one end face when the bolt is inserted into the metal profile part.

Wenn in weiterer Ausgestaltung der Erfindung der Bolzen mit einem Kopf als Anschlagbund versehen ist, wird die Feinverzahnung zweckmäßig im unmittelbar an den Kopf anschließenden Bereich des Bolzens ausgebildet. Ein solcher Kopf ist zweckmäßig, weil die Einschlagtiefe des Bolzens im Metallprofilteil dadurch begrenzt werden kann. Für die Fixierung des Bolzens und für die Verdrehsicherheit desselben wäre an sich weder die Feinverzahnung erforderlich, wie oben erwähnt, noch der Kopf. Da ein Kopf mit relativ geringer axialer Dicke eingesetzt werden kann, besteht gerade beim Einsatz bei Kunststoff-Fenstern trotzdem die Möglichkeit, den gesamten Bolzen innerhalb des Kunststoffhohlprofilteils unterzubringen, zumal ja das bei Kunststoff-Fenstern in das Kunststoffhohlprofilteil eingesetzte Metallprofilteil gegenüber den Innenwandungen des Kunststoffhohlprofilteils umfangsgeschlossen ein entsprechendes Spiel aufweist.If, in a further embodiment of the invention, the bolt is provided with a head as a stop collar, the fine toothing is expediently formed in the region of the bolt directly adjoining the head. Such a head is useful because the depth of impact of the bolt in the metal profile part can be limited. Neither the fine toothing, as mentioned above, nor the head would be required for fixing the bolt and for preventing it from rotating. Since a head with a relatively small axial thickness can be used, there is still the possibility, especially when using plastic windows, to accommodate the entire bolt inside the plastic hollow profile part, especially since the metal profile part used in plastic windows in the plastic hollow profile part is circumferentially closed to the inner walls of the plastic hollow profile part has a corresponding game.

Es ist zwar aus Pöschl, Verbindungselemente der Feinwerktechnik, Springer-Verlag 1954, Seiten 58 und 59, und aus der DD-PS 112 676 bekannt, Bolzen mit einer Feinverzahnung zur sicheren und dauerhaften Befestigung des Bolzens in einer zugeordneten Bohrung zu versehen, jedoch nicht in Verbindung mit einem Bolzen, der im Metallprofilteil des Pfostens eines Kunststoff-Fensters eingesetzt wird und bei dem die Feinverzahnung praktisch nur solange zur Verlier- und Lagesicherung im Metallprofilteil dient, bis die Spannschraube in die Gewindebohrung des Bolzens eingesetzt und angezogen ist.It is known from Pöschl, connecting elements of Feinwerktechnik, Springer-Verlag 1954, pages 58 and 59, and from DD-PS 112 676 to provide bolts with fine toothing for secure and permanent fastening of the bolt in an assigned hole, but not in connection with a bolt, which is used in the metal profile part of the post of a plastic window and in which the fine toothing serves practically only for securing and securing the position in the metal profile part until the clamping screw is inserted and tightened in the threaded hole of the bolt.

Two embodiments of the invention are described below with reference to the drawings. Show it:

in the same views as in FIGS. 1 to 4, a second embodiment of the connecting device according to the invention, in which the bolt of the connecting element and a metal profile part, in which it is inserted, are somewhat modified compared to the first embodiment.

Die Fig. 1 bis 4 und die Fig. 5 bis 8 zeigen zwei verschiedene Ausführungsformen einer Verbindungsvorrichtung zur gegenseitigen Fixierung eines Pfostens 3 und eines Riegels 4 eines Kunststoff-Fensters. Der Pfosten 3 und der Riegel 4 können dabei in einem spitzen oder rechten Winkel zueinander ausgerichtet sein. In den hier dargestellten Ausführungsbeispielen sind sie unter einem rechten Winkel zueinander ausgerichtet. Der Riegel 4 besteht aus einem Kunststoffhohlprofil 6 mit einem in dieses eingeschobenen Metallprofilteil 8, das in den dargestellten Ausführungsbeispielen ebenfalls ein Hohlprofilteil ist. Der Pfosten 3 besteht aus einem Kunststoffhohlprofilteil 5, in das ein Metallprofilteil 7 eingeschoben ist, das bei den hier dargestellten Ausführungsbeispielen ebenfalls ein Hohlprofilteil ist. Das Metallprofilteil 7 ist bei beiden Ausführungsbeispielen Teil der Verbindungsvorrichtung, da der Kraftfluß über dieses Metallprofilteil geht, was weiter unten ausführlicher beschrieben ist.1 to 4 and FIGS. 5 to 8 show two different embodiments of a connecting device for mutually fixing a post 3 and a bolt 4 of a plastic window. The post 3 and the bolt 4 can be aligned at an acute or right angle to each other. In the exemplary embodiments shown here, they are aligned at a right angle to one another. The bolt 4 consists of a plastic hollow profile 6 with a metal profile part 8 inserted into it, which is also a hollow profile part in the exemplary embodiments shown. The post 3 consists of a plastic hollow profile part 5, into which a metal profile part 7 is inserted, which is also a hollow profile part in the exemplary embodiments shown here. The metal profile part 7 is part of the connecting device in both exemplary embodiments, since the power flow passes through this metal profile part, which is described in more detail below.

Die beiden dargestellten Ausführungsbeispiele unterscheiden sich hauptsächlich dadurch, daß sich das Metallprofilteil beim ersten Ausführungsbeispiel nach den Fig. 1 bis 4 im wesentlichen durchgehend über die Länge des Pfostens 3 bis zu dessen anderem, nicht dargestellten Ende erstreckt, wogegen das Metallprofilteil 7 beim Ausführungsbeispiel nach den Fig. 5 bis 8 ein kurzes Stück ist, das sich nur in dem in Fig. 5 dargestellten Bereich der Verbindung zwischen dem Pfosten 3 und dem Riegel 4 erstreckt.The two exemplary embodiments shown differ mainly in that the metal profile part in the first exemplary embodiment according to FIGS. 1 to 4 extends essentially continuously over the length of the post 3 to its other end, not shown, whereas the metal profile part 7 in the exemplary embodiment according to FIGS 5 to 8 is a short piece that extends only in the area of the connection between the post 3 and the bar 4 shown in FIG. 5.

Weiter unterscheiden sich die beiden dargestellten Ausführungsbeispiele der Verbindungsvorrichtung im wesentlichen lediglich dadurch, daß ein Bolzen 1, der gemeinsam mit einer Spannschraube 2 ein Verbindungselement zwischen dem Pfosten 3 und dem Riegel 4 bildet, im einen Fall mit einem Kopf 18 und im anderen Fall ohne einen derartigen Kopf versehen ist, was ebenfalls weiter unten noch näher erläutert ist. Die folgenden Ausführungen gelten daher für beide Ausführungsbeispiele` sofern nichts anderes angegeben ist.Furthermore, the two illustrated embodiments of the connecting device differ essentially only in that a bolt 1, which together with a clamping screw 2 forms a connecting element between the post 3 and the bolt 4, in one case with a head 18 and in the other case without one such head is provided, which is also explained in more detail below. The following explanations therefore apply to both exemplary embodiments, unless stated otherwise.

Schließlich bilden Schrauben 17, die als Befestigungseinrichtung zur gegenseitigen Kraftübertragung zwischen dem Kunststoffhohlprofilteil 5 und dem Metallprofilteil 7 des Pfostens 3 vorgesehen sind und von denen in den Fig. 1 und 5 jeweils nur eine dargestellt ist, einen Teil der Verbindungsvorrichtung. Die dargestellten Schrauben 17 sind sich ihr Gewinde selbst schneidende und ihre Bohrung selbst bohrende Schrauben, die sich in eingeschraubtem Zustand parallel zum Bolzen 1 durch das Kunststoffhohlprofilteil 5 und das Metallprofilteil 7 erstrecken.Finally, screws 17, which are provided as fastening means for the mutual transmission of force between the plastic hollow profile part 5 and the metal profile part 7 of the post 3 and of which only one is shown in FIGS. 1 and 5, form part of the connecting device. The screws 17 shown are self-tapping and self-drilling screws which, when screwed in, extend parallel to the bolt 1 through the plastic hollow profile part 5 and the metal profile part 7.

Das bereits erwähnte Verbindungselement, das aus dem Bolzen 1 und der Spannschraube 2 besteht, dient zusammen mit dem Metallprofilteil 7 und den Schrauben 17 zur gegenseitigen Fixierung des Pfostens 3 und des Riegels 4, die in einem rechten Winkel zueinander ausgerichtet sind, beim Zusammenbau von Kunststoff-Fenstern.The aforementioned connection element, which consists of the bolt 1 and the clamping screw 2, together with the metal profile part 7 and the screws 17 serves to fix the post 3 and the bolt 4, which are aligned at right angles to one another, when assembling plastic Windows.

Der Bolzen 1 ist in eine Querbohrung im Metallprofilteil 7 eingesetzt und weist eine quer zu seiner Längsachse ausgerichtete Gewindebohrung 9 auf. In diese Gewindebohrung 9 ist der mit einem Gewinde 10 versehene Schaft 11 der Spannschraube 2 eingedreht, wobei der Schaft 11 am freien Ende mit einer Suchspitze 12 ausgestattet ist, um die Gewindebohrung 9 beim Einschrauben einfacher zu erreichen. Die Spannschraube 2 ist ferner mit einem Schraubenkopf 13 ausgestattet welcher zweckmäßig einen entsprechend großen Durchmesser aufweist. Der Schraubenkopf 13 ist mit einem Schlüsselangriff 14 ausgestattet, der vorteilhaft als Innenangriff ausgeführt ist. Es wäre aber auch denkbar, den Schlüsselangriff am Schraubenkopf 13 als Außenangriff auszuführen. Unterhalb des Schraubenkopfes 13 kann gegebenenfalls eine Dichtscheibe eingesetzt werden.The bolt 1 is inserted into a transverse bore in the metal profile part 7 and has a threaded bore 9 oriented transversely to its longitudinal axis. The threaded shaft 10 of the clamping screw 2 is screwed into this threaded bore 9, the shaft 11 being equipped at the free end with a search tip 12 in order to make it easier to reach the threaded bore 9 when screwing in. The clamping screw 2 is also equipped with a screw head 13 which expediently has a correspondingly large diameter. The screw head 13 is equipped with a key attack 14, which is advantageously designed as an internal attack. But it would also be conceivable to carry out the key attack on the screw head 13 as an external attack. A sealing washer can optionally be used below the screw head 13.

Zum Einsetzen der Spannschraube 2 sind in den oberen Abschnitten der Profilteile 6 und 8 entsprechend große Bohrungen 15, 16 vorgesehen, damit der Schraubenkopf 13 hindurchgeführt werden kann. In den unteren, gegenüberliegenden Abschnitten der Profilteile 6 und 8 sind Durchgangsbohrungen vorgesehen, welche geringfügig größer ausgeführt sind als der Schaftdurchmesser der Spannschraube 2. Die großen oberen Bohrungen 15, 16 können nachträglich mit einer Verschlußkappe verschlossen werden.To insert the clamping screw 2, correspondingly large bores 15, 16 are provided in the upper sections of the profile parts 6 and 8 so that the screw head 13 can be passed through. Through holes are provided in the lower, opposite sections of the profile parts 6 and 8, which are made slightly larger than the shank diameter of the clamping screw 2. The large upper holes 15, 16 can be subsequently closed with a sealing cap.

Bei der Ausführungsform nach den Fig. 1 bis 4 ist der Bolzen 1 mit dem Kopf 18 versehen. Die für den Bolzen 1 im Metallprofilteil 7 vorgesehene Querbohrung entspricht im Durchmesser derart dem Außendurchmesser des Bolzens 1, daß sie den Bolzen mit Festsitz aufnimmt. Der Bolzen 1 wird dabei so in die Querbohrung eingesetzt, daß seine Gewindebohrung 9 richtig auf die Spannschraube 2 ausgerichtet ist. Der Durchmesser der Querbohrung könnte auch etwas größer bemessen sein, so daß der Bolzen darin noch drehbar wäre, schließlich müßte er aber in der Querbohrung trotzdem gegen Verdrehen und axiales Verschieben gesichert werden, bis die Spannschraube in die Gewindebohrung 9 eingeschraubt ist. Diese Sicherung kann durch Kleben, Schweißen oder aber eine im folgenden noch näher beschriebene Feinverzahnung 19 erfolgen.In the embodiment according to FIGS. 1 to 4, the bolt 1 is provided with the head 18. The cross bore provided for the bolt 1 in the metal profile part 7 corresponds in diameter to the outer diameter of the bolt 1 such that it receives the bolt with a tight fit. The bolt 1 is inserted into the transverse bore so that its threaded bore 9 is correctly aligned with the clamping screw 2. The diameter of the transverse bore could also be dimensioned somewhat larger, so that the bolt would still be rotatable therein, but finally it would still have to be secured in the transverse bore against twisting and axial displacement until the clamping screw is screwed into the threaded bore 9. This securing can be done by gluing, welding or a fine toothing 19 described in more detail below.

Die Feinverzahnung 19 ist am Bolzen 1 an dessen dem Kopf 18 benachbarten Ende vorgesehen. Die Feinverzahnung 19 ist achsparallel zur Längsachse des Bolzens 1 ausgerichtet. Es ist auch möglich, anstelle der Feinverzahnung 19 entsprechend achsparallel zur Bolzenachse ausgerichtete Erhebungen, Riefen, Stege oder dergleichen oder aber eine Rändelung vorzusehen. Die Länge der Feinverzahnung 19 in Achsrichtung des Bolzens 1 gesehen ist relativ kurz, zumal diese nur den Bereich der Wandungsdicke des Metallprofilteils 7 abdecken muß. Es ist daher auch ein einfaches Einführen des Bolzens 1 in die Querbohrung im Metallprofilteil 7 möglich, so daß erst dann ein kraftbedingtes Einsetzen notwendig wird, sobald die Feinverzahnung 19 mit der Außenseite des Metallprofilteils 7 in Eingriff kommt. Der Bolzen kann also zuerst in die Querbohrung in den beiden einander gegenüberliegenden Wandungen des Metallprofilteils 7 eingeführt werden, so daß die axiale Ausrichtung des Bolzens von vorneherein gewährleistet ist. An dem zum Kopf 8 entgegengesetzten Ende ist der Bolzen 1 mit einer kegelförmigen Vertiefung 22 versehen, mit deren Hilfe der Bolzen 1 beim Einführen in das Metallprofilteil 7 zentriert werden kann. Wenn der Bolzen 1 keinen Kopf aufweist, wie z.B. der in den Fig. 5, 6 und 7 dargestellte Bolzen, sind zweckmäßig beide Stirnseiten desselben mit einer kegelförmigen Vertiefung 22 versehen, wie es in Fig. 7 gezeigt ist. Beim endgültigen Einschlagen des Bolzens 1 in das Metallprofilteil 7 greift die Feinverzahnung 19 in die ihr benachbarte Bohrungswandung im Metallprofilteil 7 ein und bewirkt so eine verdrehsichere Halterung. Zusätzlich ist auch eine Verliersicherung gegeben, da der Bolzen sich nicht von selbst wieder in axialer Richtung verschieben kann.The fine toothing 19 is provided on the bolt 1 at the end adjacent to the head 18. The fine toothing 19 is aligned axially parallel to the longitudinal axis of the bolt 1. It is also possible, instead of the fine toothing 19, to provide elevations, grooves, webs or the like which are oriented axially parallel to the bolt axis or knurling. The length of the fine toothing 19 seen in the axial direction of the bolt 1 is relatively short, especially since it only has to cover the area of the wall thickness of the metal profile part 7. It is therefore also possible to simply insert the bolt 1 into the transverse bore in the metal profile part 7, so that force-dependent insertion is only necessary as soon as the fine toothing 19 comes into engagement with the outside of the metal profile part 7. The bolt can therefore first be inserted into the transverse bore in the two opposite walls of the metal profile part 7, so that the axial alignment of the bolt is guaranteed from the outset. At the end opposite the head 8, the bolt 1 is provided with a conical recess 22, by means of which the bolt 1 can be centered when it is inserted into the metal profile part 7. If the bolt 1 has no head, e.g. 5, 6 and 7, both ends of the same are expediently provided with a conical recess 22, as shown in FIG. 7. When the bolt 1 is finally driven into the metal profile part 7, the fine toothing 19 engages in the wall of the hole adjacent to it in the metal profile part 7 and thus brings about a rotation-proof mounting. In addition, there is also a captive lock, since the bolt cannot move in the axial direction by itself.

Durch den Kopf 18 des Bolzens 1 ist eine Lagesicherung des Bolzens 1 beim Einschlagen desselben gewährleistet, so daß also ein zu tiefes Einschlagen verhindert wird. Der Bolzen 1 samt dem Kopf 18 weist eine Länge auf, die im wesentlichen der Dicke D des Metallprofilteils 7 entspricht und die lichte Weite W des Kunststoffhohlprofilteils nicht übersteigt, so daß er im wesentlichen nur in die beiden einander gegenüberliegenden Wandungen des Metallprofilteils 7 eingreift (vgl. Fig. 1 und 5). Das ermöglicht, eine Baugruppe aus dem Metallprofilteil 7 und einem oder zwei Bolzen 1 vorzumontieren und dann diese Baugruppe in das Kunststoffhohlprofil 5 des Pfostens 3 einzuführen. Anschließend wird das Metallprofilteil 7 im Kunststoffhohlprofilteil mit Hilfe von einer oder mehreren Schrauben 17 lagefixiert. Der gesamte Bolzen 1 liegt nach der Vormontage innerhalb des Kunststoffhohlprofilteils 5 des Pfostens 3. Montagebedingt wird etwas Spiel zwischen der Innenseite des Kunststoffhohlprofilteils 5 und der Außenseite des Metallprofilteils 7 vorgesehen.The head 18 of the bolt 1 ensures that the bolt 1 is secured in position when it is driven in, so that it is prevented from being driven in too deeply. The bolt 1 together with the head 18 has a length which corresponds essentially to the thickness D of the metal profile part 7 and does not exceed the inside width W of the plastic hollow profile part, so that it engages essentially only in the two opposite walls of the metal profile part 7 (cf. 1 and 5). This makes it possible to pre-assemble an assembly from the metal profile part 7 and one or two bolts 1 and then to insert this assembly into the plastic hollow profile 5 of the post 3. The metal profile part 7 is then fixed in position in the plastic hollow profile part with the help of one or more screws 17. After preassembly, the entire bolt 1 lies within the plastic hollow profile part 5 of the post 3. Due to the assembly, some play is provided between the inside of the plastic hollow profile part 5 and the outside of the metal profile part 7.

Nachdem das Metallprofilteil 7 mit eingesetztem Bolzen mittels der Schrauben 17 im Kunststoffhohlprofilteil 5 lagefixiert worden ist, können der Pfosten 3 und der Riegel 4 durch die Verbindungsvorrichtung gegenseitig fixiert werden, indem die Spannschraube 2 in die Gewindebohrung 9 eingeschraubt und angezogen wird. Die Spannkraft wird dabei von der Spannschraube über den Bolzen, das Metallprofilteil 7 und die Schrauben 17 auf das Kunststoffhohlprofilteil 5 übertragen. Auf die gleiche Weise läßt sich der Pfosten am anderen Ende an einem nicht dargestellten Riegel montieren, ungeachtet dessen, ob sich das Metallprofilteil 7 durchgehend im wesentlichen über die Länge des Pfostens 3 erstreckt oder nur ein kurzes Stück ist, das sich nur im Verbindungsbereich erstreckt, wie es in Fig. 5 gezeigt ist.After the metal profile part 7 with the inserted bolt has been fixed in position by means of the screws 17 in the plastic hollow profile part 5, the post 3 and the transom 4 can be mutually fixed by the connecting device by screwing the tightening screw 2 into the threaded bore 9 and tightening it. The clamping force is transmitted from the clamping screw via the bolt, the metal profile part 7 and the screws 17 to the plastic hollow profile part 5. In the same way, the post can be mounted at the other end on a latch, not shown, regardless of whether the metal profile part 7 extends continuously substantially over the length of the post 3 or is only a short piece that only extends in the connection area, as shown in Fig. 5.

Der Kopf 18 weist gemäß Fig. 3 einen Innenangriff 20 für ein entsprechendes Drehwerkzeug auf, so daß die Lage des Bolzens 1 vor dem endgültigen Einschlagen eingerichtet werden kann. Um eine bezogen auf die notwendige Ausrichtung der Gewindebohrung 9 ordnungsgemäße Lagefixierung zu ermöglichen, sind an der Stirnseite des Kopfes 18 Markierungsvertiefungen 21 vorgesehen, welche parallel zur Achse der Gewindebohrung 9 oder aber um 90° verdreht zu dieser ausgerichtet sind. Anstelle der Markierungsvertiefungen können natürlich auch Markierungserhebungen vorgesehen werden. Es wäre auch denkbar, am Außenumfang des Kopfes 18 entsprechende Markierungskerben oder Markierungserhebungen vorzusehen.According to FIG. 3, the head 18 has an internal engagement 20 for a corresponding turning tool, so that the position of the bolt 1 can be set up before the final impact. In order to enable proper position fixation in relation to the necessary alignment of the threaded bore 9, 18 marking recesses 21 are provided on the end face of the head, which are aligned parallel to the axis of the threaded bore 9 or rotated by 90 ° to the latter. Instead of the marking recesses, marking surveys can of course also be provided. It would also be conceivable to provide corresponding marking notches or marking elevations on the outer circumference of the head 18.

Eine Konstruktionsvariante des Verbindungselements bestünde darin, anstelle der Gewindebohrung 9 lediglich eine Durchgangsbohrung vorzusehen, wobei dann an der Spannschraube 2 ein selbstschneidendes Gewinde vorzusehen wäre.A design variant of the connecting element would be to provide only a through hole instead of the threaded hole 9, in which case a self-tapping thread would then have to be provided on the clamping screw 2.

Eine weitere Konstruktionsvariante des Verbindungselements zeigt die Ausführungsform der Verbindungsvorrichtung nach den Fig. 5 bis 8. In dieser Ausführungsform ist der Bolzen 1 ohne den Kopf 18 ausgeführt, da dieser lediglich eine Montageerleichterung beim Einschlagen des Bolzens 1 mit sich bringt. Als Innenangriff 20 für ein nicht dargestelltes Drehwerkzeug ist gemäß der Darstellung in Fig. 7 ein Schlitz vorgesehen, in welchen z.B. eine Schraubendreherklinge einführbar ist.A further design variant of the connecting element is shown in the embodiment of the connecting device according to FIGS. 5 to 8. In this embodiment, the bolt 1 is designed without the head 18, since this only simplifies assembly when the bolt 1 is driven in. As an internal attack 20 for a turning tool, not shown, a slot is provided as shown in Fig. 7, in which e.g. a screwdriver blade can be inserted.

Bei beiden erläuterten Ausführungsformen der Verbindungsvorrichtung ging es um die Befestigung von Riegel und Pfosten von Kunststoff-Fenstern. Die hier beschriebene Verbindungsvorrichtung ist aber allgemein bei der gegenseitigen Fixierung von Hohlprofilteilen einsetzbar, also überall dort, wo Kunststoffhohlprofilteile und Metallprofilteile winkelig zueinander liegend miteinander verbunden werden sollen.Both of the illustrated embodiments of the connecting device concerned the fastening of transoms and posts of plastic windows. However, the connecting device described here is general for the mutual fixing of hollow profile parts can be used wherever plastic hollow profile parts and metal profile parts are to be connected at an angle to each other.

Die Spannschraube 2 könnte auch gegenüber der Darstellung in Fig. 1 oder 5 länger ausgeführt werden, wobei dann z.B. im Metallprofilteil 8 und gegebenenfalls auch im Kunststoffhohlprofilteil 6 anstelle der großen Bohrungen 15, 16 lediglich Durchgangsbohrungen für den Schaft 11 der Spannschraube 2 vorgesehen würden. Der Schraubenkopf läge dann an der Außenseite des Metallprofilteils 8 oder an der Außenseite des Kunststoffhohlprofilteils 6 an.The clamping screw 2 could also be made longer compared to the illustration in Fig. 1 or 5, in which case e.g. in the metal profile part 8 and possibly also in the plastic hollow profile part 6, instead of the large bores 15, 16, only through bores would be provided for the shaft 11 of the clamping screw 2. The screw head would then lie on the outside of the metal profile part 8 or on the outside of the plastic hollow profile part 6.

Bei beiden gezeigten Ausführungsbeispielen ist im Kunststoffhohlprofilteil 5 keine Querbohrung für den Bolzen erforderlich, da das Metallprofilteil 7 mit dem vormontierten Bolzen 1, der bereits lagerichtig fixiert ist, in das Kunststoffhohlprofilteil 5 eingeführt wird. Danach wird das Metallprofilteil 7, wenn es die richtige Lage im Kunststoffhohlprofilteil hat, mit diesem durch eine oder mehrere Schrauben 17 verbunden, wie es in den Fig. 1 und 5 gezeigt und oben beschrieben ist. Schließlich wird die Spannschraube 2 eingeführt und angezogen, um die gewünschte gegenseitige Fixierung von Pfosten 3 und Riegel 4 zu bewirken.In both of the exemplary embodiments shown, no transverse bore is required for the bolt in the plastic hollow profile part 5, since the metal profile part 7 is inserted into the plastic hollow profile part 5 with the preassembled bolt 1, which is already fixed in the correct position. Then the metal profile part 7, if it is in the correct position in the plastic hollow profile part, is connected to it by one or more screws 17, as shown in FIGS. 1 and 5 and described above. Finally, the clamping screw 2 is inserted and tightened in order to bring about the desired mutual fixation of the post 3 and the bar 4.
