Ces rainures sont arrangées de manière à former un V et se terminent par une ouverture commune dans la surface de contact correspondante (3). On peut introduire des attaches (5, 6) dans les rainures fraisées (4) de l'un des éléments (1). Les attaches sont deux barres profilées en forme de V, l'une des branches de chacune de ces barres pouvant être fichée ou enfoncée dans une rainure de l'un des éléments (1). Le second élément (2) peut ensuite être enfoncé sur les deux branches qui dépassent de la surface de contact. Alternativement, les deux attaches en V (5, 6) peuvent être jointes en leur pointe pour former une attache unique en X.The two elements to be connected (1, 2) have grooves (4) in their two contact surfaces (3) to be superimposed. These grooves are arranged so as to form a V and end in a common opening in the corresponding contact surface (3). One can introduce fasteners (5, 6) in the milled grooves (4) of one of the elements (1). The fasteners are two V-shaped profiled bars, one of the branches of each of these bars can be plugged in or pressed into a groove in one of the elements (1). The second element (2) can then be pressed onto the two branches which protrude from the contact surface. Alternatively, the two V-shaped fasteners (5, 6) can be joined at their point to form a single X-shaped fastener.

In the accompanying drawings, which are explained in the following description, some exemplary embodiment variants of the invention are shown.
Es zeigt:It shows:

Fig. 6 eine vereinfachte Darstellung einer solchen Vorrich¬ tung. Die beiden zu verbindenden Bauteile sind mit 1 und 2 be¬ zeichnet. Diese ebenen Flächen werden als Verbindungsflächen 3 bezeichnet. Solche stumpfe Verbindungen zweier Bauteile 1,2 sind bisher äusserst problematisch. Sind diese beiden Bauteile beispielsweise zwei Holzplatten, so genügt es nicht, sie nur zu verleimen. Arbeitet man hingegen mit Dü¬ beln, Dornen oder Stiften, so ist die Gefahr gross, dass sich die Holzplatten spalten.6 shows a simplified illustration of such a device. The two components to be connected are designated 1 and 2. These flat surfaces are referred to as connecting surfaces 3. Such blunt connections between two components 1, 2 have so far been extremely problematic. For example, if these two components are two wooden panels, it is not enough to simply glue them together. If, on the other hand, one works with dowels, thorns or pins, there is a great risk that the wooden plates will split.
Erfindungsgemäss verfährt man nun so, dass man die Verbin¬ dungsflächen 3 beider Bauteile mit Nuten 4 versieht. Er¬ forderlich sind pro Bauteil zwei parallel verlaufende, jedoch zueinander und zur Verbindungsfläche 3 geneigt ange¬ ordnete Nuten. Prinzipiell können die Neigungen der Nuten 4 beliebig sein. Optimal ist eine Neigung von 30°-60° zur Verbindungsebene 3. Entsprechend kann auch die Tiefe der Nuten 4 beliebig gewählt sein. Beides, sowohl die Tiefe wie auch die Neigung der Nuten 4, verlangt jedoch wieder eine entsprechende Ausgestaltung der darin einzuschiebenden Verbindungselemente. Es ist daher naheliegend, dies durch eine gewisse Normierung festzulegen. Wesentlich ist somit nur, dass die Nuten in den zu verbindenden Bauteilen 1,2 so angebracht werden, dass jeweils je eine Nut des einen Bauteiles zur Nut des anderen in der Verbindungslage so liegt, dass durch beide Teile zusammen eine gemeinsame V-förmige Nut gebildet wird, die sich so über die Verbin¬ dungsebene hinweg erstreckt, dass je ein Schenkel der V-förmigen Nut in jedem Bauteil 1,2 zu liegen kommt. Es ist jedoch darauf zu achten, dass die beiden aufeinander zu liegen kommenden Nuten aufeinander zu (Fig. 2) gerichtet sind.The procedure according to the invention is now such that the connecting surfaces 3 of both components are provided with grooves 4. Two grooves are required for each component, but they are arranged parallel to one another and inclined to the connecting surface 3. In principle, the inclinations of the grooves 4 can be any. An inclination of 30 ° -60 ° to the connection plane 3 is optimal. Accordingly, the depth of the grooves 4 can also be chosen as desired. Both, both the depth and the inclination of the grooves 4, however, require a corresponding design of the connecting elements to be inserted therein. It is therefore obvious to fix this by a certain standardization. It is therefore only essential that the grooves are made in the components 1, 2 to be connected in such a way that in each case one groove of the one component to the groove of the other in the connection position lies in the fact that a common V-shaped groove is formed by both parts, which extends over the connection plane such that one leg of the V-shaped groove comes to rest in each component 1, 2. However, care must be taken that the two grooves that come to lie on one another are directed towards one another (FIG. 2).
Die beiden V-förmigen Nuten sind so angebracht, dass sie zusammen, eine X-förmige Nut ergeben, wie dies in Fig. 1 dar-, gestellt ist.The two V-shaped grooves are attached so that together they form an X-shaped groove, as shown in FIG. 1.
Sind die Nuten 4 in den beiden Bauteilen 1,2 angebracht, so werden nun die Verbindungselemente 5 beziehungsweise wird das Verbindungselement.6 in die Nuten eines Bauteiles ein¬ geschoben oder eingelegt. Verwendet man ein kreuzförmiges Verbindungselement 6 wie in Fig. 1 und 3) dargestellt, so müssen sich die Nuten 4 bis zur Peripherie erstrecken, damit das Verbindungselement- 6 seitlich eingeschoben werden kann. Verwendet man hingegen zwei einzelne, V-förmige Verbindungs¬ elemente 5, so brauchen die Nuten in einem Bauelement nicht bis zur Peripherie hinaus, eingefräst zu werden, weil die Profile 5 einfach eingesteckt werden können. Die V-förmigen Profile 5 sind je an der äusseren Winkelspitze abgeflacht. So lassen sich auch zwei solcher Verbindungselemente zu einem zweiteiligen X-förmigen Verbindungselement anordnen, wie dies in Fig. 3 dargestellt ist.If the grooves 4 are made in the two components 1, 2, then the connecting elements 5 or become the connecting element . 6 inserted or inserted into the grooves of a component. If a cross-shaped connecting element 6 is used as shown in FIGS. 1 and 3), the grooves 4 must extend to the periphery so that the connecting element 6 can be inserted laterally. If, on the other hand, two individual, V-shaped connecting elements 5 are used, the grooves in a component do not need to be milled to the periphery because the profiles 5 can simply be inserted. The V-shaped profiles 5 are each flattened on the outer angle tip. In this way, two such connecting elements can also be used arrange a two-part X-shaped connecting element, as shown in Fig. 3.
Unter Verwendung des Prinzips der V-förmig angeordneten Nu¬ ten, lassen sich auch andere," hier' nicht "?ur Diskussion stehende Profile an einem Bauteil befestigen. Die Figur 4 zeigt ein solches Beispiel. Das dargestellte Profil 8 eignet sich zur Verbindung von Holz- oder Glasplatten 9. Nach derselben Art lassen sich auch Profile als Kantenschutz an Platten anbringen.Using the principle of the V-shaped arrangement, other profiles "not here " that are under discussion can also be attached to a component. Figure 4 shows such an example. The profile 8 shown is suitable for connecting wooden or glass panels 9. In the same way, profiles can also be attached to panels as edge protection.
Die für die Verbindung erforderlichen Nuten 4 lassen sich prinzipiell mit den heute bekannten Nαtenstoss- oder Nu- tenfräsmaschinen bereits ausnehmen. Solche Maschinen stehen jedoch nicht allen Handwerkern, insbesondere den Heimwerkern zur Verfügung. Die Erfindung zeigt aber auch hierfür eine einfache Lösung auf, die in Figur 6 vereinfacht dargestellt ist.The grooves 4 required for the connection can, in principle, already be cut out with the slot knocking or slot milling machines known today. However, such machines are not available to all craftsmen, especially to do-it-yourselfers. However, the invention also shows a simple solution for this, which is shown in simplified form in FIG.
Mit der Bezugszahl 10 ist hier eine Art Stativ gezeigt, welches sich fest auf einer Unterlage 11 montieren lässt. Im Stativ lässt sich einseitig eine Handbohrmaschine, die hier hinter dem Stativ und daher nicht sichtbar ist, einspannen. Auf der anderen Seite ist ein Winkelgetriebe 12 ange¬ flanscht, welches nur symbolisch gezeichnet ist und nicht die tatsächlichen Verhältnisse wiedergibt. Aus dem Getriebe ragen zwei Antriebswellen 13, die untereinander einen Winkel von 90° einschliessen. Auf diesen Antriebswellen 13 lassen sich je ein Kreissägeblatt 14. befestigen. Diese Kreissäge¬ blätter sind besonders gestaltet, so dass sie ineinander¬ greifend arbeiten können, wie dies noch, anhand der Figur 5 erläutert wird.The reference number 10 shows a type of tripod, which can be securely mounted on a base 11. A hand drill, which is here behind the tripod and therefore not visible, can be clamped into the tripod. On the other hand, an angular gear 12 is flanged, which is only drawn symbolically and does not reflect the actual conditions. From the transmission protrude two drive shafts 13 which form an angle of 90 ° with one another. A circular saw blade 14 can be attached to each of these drive shafts 13. These circular saw blades are specially designed so that they can work in an interlocking manner, as will be explained with reference to FIG. 5.
Auf dem Stativ 10 ist eine Arbeitsplatte 15 befestigt, die einen Schlitz 16 aufweist. Durch den Schlitz 16 ragen die beiden Kreissägeblätter 14. Ein verschiebbarer Anschlag 17 dient der Führung der mit Nuten zu versehenden Bauteile. Mit der beschriebenen Vorrichtung *lassen sich in einem Arbeits¬ gang zwei genau in der gewünschten Anordnung verlaufende, V-förmig zueinandergeneigte Nuten an einem Bauteil ausfrä¬ sen. Selbstverständlich kann man auch nur mit einem Kreis¬ sägeblatt 14 arbeiten und so beliebige Nuten für eine Verbindung gemäss der Figur 2 ausfräsen.On the tripod 10, a worktop 15 is attached, which has a slot 16. The two circular saw blades 14 protrude through the slot 16. A displaceable stop 17 serves to guide the components to be grooved. With the device * described, two V-shaped grooves that run exactly in the desired arrangement can be milled out on one component in one operation. Of course, it is also possible to work only with a circular saw blade 14 and thus mill out any grooves for a connection according to FIG. 2.
Das Kreissägeblatt 14 gemäss Figur 5 hat eine Vielzahl von in regelmässigen Abständen angeordneten Zacken 20. Der Ab¬ stand von zwei Zacken ist dabei grösser als die Breite der einzelnen Zacken 20. Dies erlaubt es, dass zwei zueinander geneigte Kreissägeblätter 14 ineinandergreifend getrieben werden können. Jeder Zacken 20 ist mit Sägezähnen 21 versehen. Wichtig ist, dass die beiden Sägeblätter in einer korrekten Position zueinander auf den beiden Antriebswellen montiert sind. Hierzu uss das Aufnahmeloch 22 im Kreissäge¬ blatt 14 entsprechend geformt sein. Im vorliegenden Beispiel ist hierzu die - Ausnehmung 23 vorgesehen, wobei ein ent¬ sprechender Keil oder ein Zapfen, der auf der Antriebswelle sitzt, eingreift.The circular saw blade 14 according to FIG. 5 has a multiplicity of teeth 20 arranged at regular intervals. The distance between two teeth is greater than the width of the individual teeth 20. This allows two circular saw blades 14 inclined to one another to be driven into one another. Each prong 20 is provided with saw teeth 21. It is important that the two saw blades in one correct position to each other on the two drive shafts. For this purpose, the receiving hole 22 in the circular saw blade 14 must be shaped accordingly. In the present example, the recess 23 is provided for this purpose, a corresponding wedge or a pin which sits on the drive shaft engaging.
Die Anwendung des aufgezeichneten VerbindungsSystems ist ausserordentlich vielseitig. Besonders vorteilhaft ist die Anwendung im Möbelbau und Holzformenbau. In diesen Bereichen verwendet man sinnvollerweise Verbindungselemente aus Metall oder Kunststoff. Aber auch die nachträgliche Verbindung eines flachen Bauteiles mit einem bestehenden Betonbauteil ist auf diese Art möglich. The application of the recorded connection system is extremely versatile. The use in furniture construction and wood mold construction is particularly advantageous. In these areas, connecting elements made of metal or plastic are expediently used. The subsequent connection of a flat component to an existing concrete component is also possible in this way.
