Abstract
Description
Die vorliegende Erfindung betrifft eine Verbindungsvorrichtung zum starren verbinden eines ersten Profils mit einem weiteren Profil, die insbesondere eine vor dem Verbinden erforderliche vorbereitende Bearbeitung eines Profils entbehrlich macht.The The present invention relates to a rigid connection device connect a first profile with another profile, in particular a preparatory processing of a required before connecting Profile.
Verbindungsvorrichtungen zum starren Verbinden von Profilen sind in verschiedenen Ausgestaltungen seit langem bekannt. Unter Profilen werden allgemein stangenförmige Erzeugnisse verstanden, die eine definierte Querschnittsgeometrie aufweisen. Die Querschnittsgeometrie ändert sich hierbei im allgemeinen über der gesamten Länge des Erzeugnisses nicht oder nicht wesentlich. Im folgenden werden unter dem Begriff Profil einschränkend nur solche verstanden, die über obige Definition hinaus zumindest eine sich über die gesamte Länge des Profils erstreckende Ausnehmung aufweisen, wobei die Ausnehmung über einen sich ebenfalls über die gesamte Länge des Profils erstreckenden Schlitz von der Außenseite des Profils zugänglich ist. Eine derart ausgestaltete Ausnehmung wird als Hinterschneidung bezeichnet. Die Breite des Schlitzes ist geringer als die Ausdehnung der Ausnehmung quer zur Längsrichtung des Profils. Um als Hohlprofil zu gelten, weist ein entsprechendes Profil darüber hinaus eine, mit Bezug auf den Querschnitt des Hohlprofils nach außen abgeschlossene, sich in Längsrichtung des Profils erstreckende Ausnehmung bzw. Bohrung auf. Diese wird im folgenden als Hohlbohrung bezeichnet. Der Querschnitt der Hohlbohrung kann beliebig geformt sein; er muss nicht notwendigerweise rund ausgeführt sein. Falls das Hohlprofil im Querschnitt symmetrisch ausgebildet ist, verläuft die Hohlbohrung in der Regel zentral zur Symmetrieachse. Profile können im Querschnitt beliebig ausgebildet sein. Die häufigsten Formen sind rund, dreieckig, viereckig oder sie besitzen die Form eines regelmäßigen Vielecks. Ein Hohlprofil mit einem viereckigen Querschnitt besitzt in der Regel vier sich längs erstreckende Hinterschneidungen. Bei einfachen Profilen ist oft nur eine sich längs erstreckende Hinterschneidung vorhanden. Die beschriebenen Profile und Hohlprofile sind in der Regel als Aluminium-Strangpressprofile ausgebildet.connecting devices for rigid connection of profiles are in different configurations known for a long time. Profiles are generally rod-shaped products understood that have a defined cross-sectional geometry. The Cross-sectional geometry changes generally about the entire length of the product not or not materially. The following are under restricting the term profile only understood those who over above definition at least one over the entire length of the Have profile extending recess, the recess over a also about the entire length of the profile extending slot is accessible from the outside of the profile. Such a recess is referred to as an undercut. The width of the slot is less than the extent of the recess transverse to the longitudinal direction of the profile. In order to be considered a hollow profile, a corresponding one Profile about it in addition, a closed off with respect to the cross section of the hollow profile, itself in the longitudinal direction of the profile extending recess or bore. This will hereinafter referred to as a hollow bore. The cross section of the hollow bore can have any shape; it does not necessarily have to be round accomplished his. If the hollow profile is symmetrical in cross section is going the hollow bore generally central to the axis of symmetry. profiles can be of any cross-section. The most common shapes are round, triangular, quadrangular or they have the shape of a regular polygon. A hollow profile with a square cross section has in the Rule four along extending undercuts. With simple profiles is often only one along extending undercut present. The profiles described and hollow profiles are usually designed as extruded aluminum profiles.
Wie
bereits erwähnt,
sind verschiedene Verbindungsvorrichtungen zum Verbinden von Profilen bekannt.
Beispielsweise offenbaren die Schweizer Patentschrift
Bei diesen bekannten Verbindungsvorrichtungen muss zur Aufnahme eines Einsatzstückes und/oder einer Spannschraube das Hohlprofil zuerst mit einer Bohrung versehen werden. Hierzu sind Werkzeuge erforderlich, die im allgemeinen nur im Werkzeugfachhandel erhältlich sind. Von Nachteil ist dies insbesondere, wenn vor Ort an einen bereits bestehenden Profilrahmen ein zusätzliches Profil angebracht werden soll. Ist kein passendes Bohrwerkzeug vorhanden, muss dieses meist erst beim Hersteller der Verbindungsvorrichtung oder im Fachhandel mit erheblichen Aufwand besorgt werden.at these known connecting devices must be used to accommodate a Insert and / or First use a clamping screw to drill the hollow profile become. Tools are required for this, which in general only available in tool shops are. This is particularly disadvantageous when on site at one existing profile frame an additional profile attached shall be. If there is no suitable drilling tool, this must be done usually only at the manufacturer of the connection device or in specialist shops be concerned with considerable effort.
Es ist somit Aufgabe der vorliegenden Erfindung, eine Verbindungsvorrichtung zum starren Verbinden eines ersten Hohlprofils mit einem weiteren Profil bereitzustellen, die ein Verbinden der Profile ohne spezielle vorbereitende Bearbeitung wie z. B. ein Anfertigen einer Aufnahmebohrung ermöglicht.It is therefore an object of the present invention, a connecting device for rigid connection of a first hollow profile with another profile to provide a joining of the profiles without any special preparatory Processing such as B. allows you to make a location hole.
Diese Aufgabe wird durch eine Verbindungsvorrichtung zum starren Verbinden eines ersten Hohlprofils mit einem weiteren Profil gemäß den beigefügten Anspruch 1 gelöst. Die verbindungsgemäße Vorrichtung umfasst ein ankerförmiges Verbindungselement das ein, mit einer kegelförmigen Aussparung versehenes Schaftteil aufweist, welches in einer Hohlbohrung des ersten Hohlprofils angeordnet werden kann, und das weiterhin ein Kopfteil aufweist, das in eine Hinterschneidung des weiteren Profils eingreifen kann. Die erfindungsgemäße Verbindungsvorrichtung umfasst weiterhin ein Spannlager, das in eine Hinterschneidung des ersten Hohlprofils eingeführt werden kann sowie ein Spannelement mit einem sich verjüngenden Ende an dem zumindest eine Schneide ausgebildet ist. Das Spannelement ist hierbei so ausgeführt, dass es in einer Öffnung des Spannlagers geführt werden kann und geeignet ist mit der zumindest einen Schneide das Material des ersten Hohlprofils zwischen dessen Hinterschneidung und dessen Hohlbohrung zu durchdringen und so in die kegelförmige Aussparung des Schaftteils einzugreifen, dass es das ankerförmige Verbindungselement in der Hohlbohrung des ersten Hohlprofils in dessen Längsrichtung verspannt.This object is achieved by a connecting device for rigidly connecting a first hollow profile to a further profile according to the appended claim 1. The device according to the connection comprises an anchor-shaped connecting element which has a shaft part which is provided with a conical recess and which can be arranged in a hollow bore in the first hollow profile and which furthermore has a head part which can engage in an undercut in the further profile. The connecting device according to the invention further comprises a clamping bearing that can be inserted into an undercut of the first hollow profile and a clamping element with a tapered end on which at least one cutting edge is formed. The tensioning element is here designed so that it can be guided in an opening of the insert bearing and is suitable to penetrate with the at least one cutting edge the material of the first hollow profile between its undercut and its hollow bore and to engage in the conical recess of the shaft part such that it is the anchor-shaped connecting element clamped in the hollow bore of the first hollow profile in its longitudinal direction.
Durch die Ausführung des Spannelements als selbstschneidendes Werkstück muss das zu verbindende Profil nicht mehr vorbereitend mit einer Bohrung zur Aufnahme des Spannlagers versehen werden. Die Arbeitsvorbereitung wie auch der erforderliche Werkzeugaufwand sind hierdurch deutlich reduziert.By execution of the clamping element as a self-tapping workpiece must be the one to be connected Profile no longer preparatory with a hole to accommodate the Radial insert bearings are provided. The work preparation as well as the This significantly reduces the amount of tools required.
Damit das Verspannen der Profile mit handelsüblichem Werkzeug durchgeführt werden kann, ist dass Spannelement vorzugsweise schraubenförmig ausgestaltet.In order to the profiles can be clamped using standard tools can, the clamping element is preferably configured helically.
Zum leichten Positionieren und zum Sicherstellen einer festen Verankerung weist das Spannlager zweckmäßig eine quaderförmige Erhebung auf, die in einem Schlitz der Hinterschneidung des ersten Hohlprofils angeordnet werden kann.To the easy positioning and to ensure firm anchoring the insert bearing expediently has one cuboid Elevation on that in a slot of the undercut of the first hollow profile can be arranged.
Vorteilhafterweise weist das Spannlager ein Fixierungselement zum Fixieren des Spannlagers in der Hinterschneidung auf. Hierdurch wird das Positionieren des Spannlagers nach dem Einführen in die Hinterschneidung erleichtert. Vorteilhafterweise ist dabei das Fixierungselement ein Gewindestift, der in einer Gewindeöffnung des Spannlagers geführt ist und dieses in der Hinterschneidung verspannt. Nach der erfolgten Verspannung des Spannlagers mittels dem Fixierungselement kann das Spannelement mit der zumindest einen Schneide dank der ortsfesten Positionierung problemlos durch das Material des ersten Hohlprofiles zwischen der Hinterschneidung und dessen Hohlbohrung gedreht werden, um in die kegelförmige Aussparung des Schaftteils einzugreifen und dieses zu verspannen.advantageously, the radial insert bearing has a fixing element for fixing the radial insert bearing in the undercut. This will position the Radial insert after insertion relieved in the undercut. It is advantageous the fixing element is a threaded pin which is in a threaded opening of the Radial insert guided and this is clamped in the undercut. After the done Bracing the radial insert ball using the fixing element can do that Clamping element with at least one cutting edge thanks to the fixed positioning easily through the material of the first hollow profile between the Undercut and its hollow hole are rotated to fit in the conical recess of the shaft part to intervene and brace it.
Weiterhin ist es von Vorteil, am Spannlager oder als zusätzliches Element zum Spannlager einen Abstandshalter oder Maßstab vorzusehen, der die richtige Entfernung und Position des Spannlagers vom Ende des ersten Hohlprofiles dergestalt angibt, dass beim Eindrehen des Spannelementes gewährleistet ist, dass es in die kegelförmige Aussparung des Schaftteils an der richtigen Stelle eingreift und das Schaftteil verspannt.Farther it is advantageous to use the insert bearing or as an additional element to the insert bearing a spacer or scale to provide the correct distance and position of the insert from End of the first hollow profile indicates that when screwing guaranteed of the clamping element is that it's in the conical Recess of the shaft part engages in the right place and that Tensioned shaft part.
