Description

Titel: Klemmverbindung für einen Türflügel aus Glas  Title: Clamp connection for a glass door leaf
Beschreibung Die Erfindung betrifft eine Klemmverbindung zum klemmenden Haltern eines Türflügels aus Glas, mit einem Klemmschuh, der den Türflügel randseitig umfasst und mit Mitteln zum Aufbringen einer Klemmkraft. The invention relates to a clamping connection for the clamping holding a door leaf made of glass, with a clamping shoe, which includes the door wing edge and with means for applying a clamping force.
Bekannte Klemmverbindungen weisen in der Regel einen den Schiebeflü- gel einspannenden Klemmschuh auf, welcher über einen Tragbolzen hängend mit einem über dem Klemmschuh angeordneten, in einer Laufschiene geführtem Rollenwagen verbunden ist. Da grundsätzlich auf Bohrungen oder Ausnehmungen im Schiebeflügel verzichtet werden soll, wird die für die Einspannung des Schiebeflügels im Klemmschuh erforderliche Haftreibungskraft durch eine Schraubverbindung aufgebracht. Die Schraubverbindung ist im Bereich der oberen Stirnseite des Schiebeflügels angeordnet und presst die beiden Seitenwangen, die eine nutförmige Ausnehmung des Klemmschuhes bilden, seitlich gegen die Planflächen des Schiebeflügels. In Folge der Anordnung der Schraubverbindung ober- halb der oberen stirnseitigen Begrenzung des Schiebeflügels ergibt sich zwangsläufig zum Einen eine große Bauhöhe des Klemmschuhes; zum Anderen ist auf Grund der vorbeschriebenen Hebelverhältnisse die Aufbringung einer relativ hohen Klemmkraft im Bereich der Schraubverbindung und die Wahl eines für die vorbeschriebene Klemmverbindung ge- eignete Material erforderlich. Known clamping connections generally have a sliding shoe clamping the sliding block, which is connected by a supporting bolt suspended to a roller shoe arranged above the clamping shoe and guided in a running rail. Since in principle should be dispensed with holes or recesses in the sliding leaf, the required for the clamping of the sliding leaf in the clamping shoe static friction force is applied by a screw. The screw is arranged in the region of the upper end side of the sliding leaf and presses the two side cheeks, which form a groove-shaped recess of the clamping shoe, laterally against the flat surfaces of the sliding leaf. As a result of the arrangement of the screw above the upper frontal boundary of the sliding leaf results inevitably on the one hand a large height of the clamping shoe; On the other hand, the application of a relatively high clamping force in the region of the screw connection and the choice of a suitable for the above-described clamping connection material is required due to the above-described leverage.
Die DE 102004050596 A1 zeigt einen kompakten Rollenwagen für eine Schiebetür aus Glas, bei der das Türelement im Bereich seiner Stirnkante u-förmig umgriffen und durch mindestens zwei Schrauben direkt oder indirekt geklemmt wird. Dabei ergibt sich bei schweren Türen von z.B. 150 DE 102004050596 A1 shows a compact roller carriage for a sliding glass door, in which the door element is embraced in the region of its front edge U-shaped and is clamped directly or indirectly by at least two screws. This results in heavy doors of e.g. 150
BESTÄTIGUNGSKOPIE kg eine so große Flächenpressung auf die Glasscheibe, dass diese beim Einleiten einer weiteren Kraft - z.B. beim Stoppen der Tür oder ruckartigen Öffnen - zerstört wird. Die Aufgabe der Erfindung besteht darin, eine preiswerte Klemmverbindung für den Flügel einer Tür aus Glas zu schaffen, die auch für große und schwere Glastüren geeignet ist. CONFIRMATION COPY kg such a large surface pressure on the glass, that it is destroyed by the introduction of another force - eg when stopping the door or jerky opening. The object of the invention is to provide an inexpensive clamping connection for the wing of a glass door, which is also suitable for large and heavy glass doors.
Die Erfindung löst die gestellte Aufgabe mit der Lehre nach Anspruch 1. Weitere ausgestaltende Merkmale der Erfindung sind Gegenstand der Unteransprüche. The invention solves this problem with the teaching of claim 1. Further ausgestaltende features of the invention are the subject of the dependent claims.
Die Klemmverbindung umfasst einen Klemmschuh, der den Türflügel randseitig umfasst, und Mittel zum Aufbringen der Klemmkraft. Zur Ver- meidung von Spannungsspitzen sind im Bereich der Angriffsfläche der Klemmkraft eine oder mehrere Ausnehmungen angeordnet, mit denen die Spannungsspitze der Klemmkraft reduziert wird. Die Ausnehmung ist dabei so am oder im Klemmschuh angeordnet, dass sich die Klemmkraft, die auf die Glasscheibe wirkt, um die Angriffsfläche verteilt. Die Druckflä- che wird damit größer, die Flächenpressung geringer und die Spannungsspitze aufgrund der Hertzschen Pressung reduziert sich. Damit kann bei gleichen Abmessungen des Rollenwagens und der Laufschiene eine größere und schwerere Glastür als nach dem Stand der Technik klemmend gehaltert werden. The clamping connection comprises a clamping shoe, which includes the edge of the door, and means for applying the clamping force. To avoid stress peaks, one or more recesses are arranged in the region of the engagement surface of the clamping force with which the stress peak of the clamping force is reduced. The recess is arranged on or in the clamping shoe, that distributes the clamping force acting on the glass to the attack surface. As a result, the pressure surface becomes larger, the surface pressure is reduced and the stress peak due to the Hertzian pressure is reduced. This can be clamped with the same dimensions of the roller carriage and the running rail a larger and heavier glass door than in the prior art.
Die Mittel zur Aufbringung der Klemmkraft auf die Glasscheibe umfassen mindestens eine Stellschraube. Da die Stellschraube trotz Verteilung der Kraft über eine Klemmplatte eine fast punktförmige Druckkraft auf der Glasscheibe erzeugt, sorgt die Ausnehmung für eine Verlagerung der Druckspannung auf den Randbereich der Ausnehmung, wodurch die Spannungsspitzen aufgrund der ringförmigen Flächenpressung kleiner ausfallen. The means for applying the clamping force to the glass sheet comprise at least one set screw. Since the screw generates a nearly punctiform pressure force on the glass pane despite distribution of the force via a clamping plate, the recess ensures a displacement of the compressive stress on the edge region of the recess, whereby the Voltage peaks due to the annular surface pressure smaller.
Eine besonders preiswerte Ausführung wird mit mindestens einem Glas- schütz erreicht, der üblicherweise zwischen Glasscheibe und Klemmschuh angeordnet ist. Dabei wird eine runde Vertiefung oder Bohrung in den Glasschutz eingearbeitet, was sehr preiswert durch Stanzen erfolgen kann. Die Ausnehmung kann aber auch in der Klemmplatte oder einem Seitenteil des Klemmschuhs, einer Seitenwange angeordnet sein. A particularly inexpensive embodiment is achieved with at least one glass contactor, which is usually arranged between glass pane and clamping shoe. In this case, a round depression or hole is incorporated into the glass protection, which can be done very inexpensively by punching. The recess can also be arranged in the clamping plate or a side part of the clamping shoe, a side cheek.
Da die Stellschraube eine fast punktförmige Druckkraft erzeugt, sollte die Ausnehmung möglichst zentral zur Mittelachse der Stellschraube, also an der sonst anliegenden Angriffsfläche, angeordnet werden. Die Größe der Ausnehmung sollte mindestens dem Durchmesser der Stellschraube, maximal aber dem fünffachen Durchmesser der Stellschraube entsprechen. Since the set screw produces an almost point-shaped pressure force, the recess should be arranged as centrally as possible to the central axis of the set screw, ie on the otherwise adjacent attack surface. The size of the recess should be at least equal to the diameter of the set screw, but not more than five times the diameter of the set screw.
Die Erfindung wird nachfolgend anhand einer den Stand der Technik wiedergebenden Prinzipskizze sowie einem Ausführungsbeispiel der Erfin- dung näher erläutert: The invention is explained in more detail below with reference to a schematic diagram representing the prior art and to an exemplary embodiment of the invention:

Es ist klar, dass sich die Erfindung nicht nur hierauf beschränkt, sondern auch die klemmende Befestigung von Drehflügeltüren mit umfasst. Figure 3: a detailed view of a roller carriage. The following embodiment relates to the roller carriage of a sliding door. It is clear that the invention is not limited to this, but also includes the clamping attachment of swing doors with.
Bei der Klemmverbindung 1 nach den Figuren 1 und 2 weist ein Klemmschuh 2 eine nach unten offene Nut 9 auf, die jedoch im Ausführungsbeispiel breiter ausgeführt sein kann, um Glasscheiben 3 unterschiedlicher Dicke einspannen zu können. Die Glasscheibe 3 ist im Bereich einer Klemmkammer 5 mit ihrer oberen Stirnseite 10 etwa bis in den Bereich eines Nutgrundes 11 der Nut 9 durchgeführt. Dies bedeutet, dass das von einer Stellschraube 6 aufgebrachte Anzugsdrehmoment unmittelbar auf eine Planfläche 7 der Glasscheibe 3 übertragen werden kann. Mit 15 ist ein Glasschutz bezeichnet, der einerseits im Klemmschuh 2 an der Sei- tenwange 16 anliegt, und andererseits an der von der Stellschraube 6 beaufschlagten Klemmplatte 8 anliegt. Der Glasschutz 15 kann dabei so ausgebildet sein, dass eine zusätzliche Reibung und damit eine erhöhte Haltekraft erzeugt wird. Nach der perspektivischen Darstellung gemäß Figur 2 bilden der Klemmschuh 2 und ein Rollenwagen 4 eine Baueinheit, d. h. der Klemmschuh 2 ist nicht über einen Tragzapfen hängend an einem Rollenwagen 4 geführt. In the clamping connection 1 according to Figures 1 and 2, a clamping shoe 2 has a downwardly open groove 9, which, however, can be made wider in the embodiment to clamp glass sheets 3 of different thickness can. The glass sheet 3 is performed in the region of a clamping chamber 5 with its upper end face 10 approximately as far as into the region of a groove bottom 11 of the groove 9. This means that the tightening torque applied by an adjusting screw 6 can be transmitted directly to a plane surface 7 of the glass pane 3. 15 designates a glass guard, which bears on the one hand in the clamping shoe 2 on the side cheek 16, and on the other hand rests against the clamping plate 8 acted upon by the adjusting screw 6. The glass guard 15 can be designed so that an additional friction and thus an increased holding force is generated. According to the perspective view of Figure 2, the clamping shoe 2 and a roller carriage 4 form a structural unit, d. H. the clamping shoe 2 is not guided over a trunnion hanging on a roller carriage 4.
Der Klemmschuh 2 besitzt hierzu eine seitliche Einziehung 12 für die Auf- nähme eines die Tragrollen 13 tragenden Rollenbockes 14. Mittels der Stellschrauben 6 kann auch im Ausführungsbeispiel nach Figur 2 die in der Klemmkammer 5 angeordnete Klemmplatte 8 gegen die Glasscheibe 3 angestellt werden. In dem Ausführungsbeispiel der Figur 2 sind insgesamt vier Stellschrauben 6 in Form von Stift- oder Madenschrauben ange- ordnet, die die Klemmplatten 8 gegen die Glasoberfläche drücken. Die Angriffsfläche, auf der sich der Druck der Klemmkraft verteilt, liegt dabei zentral um die Mittelachse der Stellschrauben 6 herum. By means of the adjusting screws 6, the clamping plate 8 arranged in the clamping chamber 5 can also be set against the glass pane 3 by means of the adjusting screws 6. In the exemplary embodiment of FIG. 2, a total of four setscrews 6 are arranged in the form of pin or grub screws, which press the clamping plates 8 against the glass surface. The Attack surface on which distributes the pressure of the clamping force is centrally around the central axis of the screws 6 around.
In dem Ausführungsbeispiel der Figur 3 ist der Glasschutz 15 im Detail zu erkennen, der im Bereich der Stellschrauben 6 Ausnehmungen 17 aufweist. Durch die Klemmung entstehen auf der Glasscheibe 3 aufgrund der Hertzschen Pressung Spannungsspitzen, die bei Addition mit zusätzlichen Kräften, z.B. aufgrund des Stoppens der Tür oder bei kleinen Defekten an der Glasoberfläche, die Glasscheibe 3 zerstören können. Zur Reduzierung der Spannungsspitzen sind Ausnehmungen 17 im Glasschutz 15 angeordnet, wodurch sich die Spannung großflächiger um die Ausnehmung 17 herum auf der Glasoberfläche verteilt. Durch die Verlagerung der Druckspannung auf den Randbereich der Ausnehmung 17 bildet sich eine ringförmige Flächenpressung aus. Die Spannungsspitzen werden dadurch in der Höhe reduziert und die Druckfläche auf der Glasoberfläche vergrößert sich um ein Vielfaches, wodurch die Flächenpressung abnimmt. In the exemplary embodiment of FIG. 3, the glass guard 15 can be seen in detail, which has recesses 17 in the region of the adjusting screws 6. As a result of the clamping, stress peaks occur on the glass pane 3 due to the Hertzian pressure which, when added with additional forces, e.g. due to the door being stopped or small defects on the glass surface, the glass pane 3 may be destroyed. To reduce the voltage peaks recesses 17 are arranged in the glass guard 15, whereby the voltage distributed over a larger area around the recess 17 around on the glass surface. Due to the displacement of the compressive stress on the edge region of the recess 17, an annular surface pressure is formed. The voltage peaks are thereby reduced in height and the pressure surface on the glass surface increases many times, whereby the surface pressure decreases.
Die Ausnehmung 17 kann als runde Bohrung oder Vertiefung am Glasschutz 15, an der Klemmplatte 8 oder auch an den Seitenwangen 16 an- geordnet sein. Dabei ist in bevorzugter Ausführungsform die Ausnehmung 17 als Bohrung im Glasschutz 15 ausgestaltet, da diese aus Kunststoff, Gummi, Pappe oder Holz hergestellt werden und preiswert herzustellen sind. Bei dem Ausführungsbeispiel nach Figur 2 mit der Anordnung von je zwei Stellschrauben 6 nebeneinander ist auch eine ellipsenförmige Aus- nehmung 17 möglich. Weitere Formen einer Ausnehmung 17 können rechteckige oder vieleckige Bohrungen oder Vertiefungen sein. The recess 17 can be arranged as a round bore or depression on the glass guard 15, on the clamping plate 8 or also on the side cheeks 16. In this case, in a preferred embodiment, the recess 17 designed as a hole in the glass 15, since they are made of plastic, rubber, cardboard or wood and are inexpensive to manufacture. In the embodiment of Figure 2 with the arrangement of two adjusting screws 6 side by side also an elliptical recess 17 is possible. Other shapes of a recess 17 may be rectangular or polygonal holes or depressions.
Die Anordnung der Ausnehmung 17 sollte bevorzugt zentral zur Mittelachse der Stellschraube 6 ausgerichtet sein, so dass sich der Druck gleich- mäßig um die Angriffsfläche der Stellschraube 6 verteilt. Je nach konstruk- tivem Aufbau und Steifigkeit des gesamten Rollenwagens 4 und dem damit verbundenen elastischen Verhalten beim Anziehen der Stellschrauben 6 kann auch eine von der Mittelachse der Stellschraube 6 exzentrische Anordnung der Ausnehmung 17 sinnvoll sein. The arrangement of the recess 17 should preferably be aligned centrally with respect to the central axis of the adjusting screw 6, so that the pressure is evenly distributed around the engagement surface of the adjusting screw 6. Depending on the construction tive structure and rigidity of the entire roller carriage 4 and the associated elastic behavior when tightening the screws 6 may also be useful from the central axis of the screw 6 eccentric arrangement of the recess 17.
Die Größe der Ausnehmung 17 im Durchmesser bzw. lichte Weite sollte mindestens dem Durchmesser der Stellschraube 6 entsprechen, maximal aber dem fünffachen Durchmesser. Bei einer Stellschraube 6 mit dem Gewinde M8 wäre damit der minimale Durchmesser der Ausnehmung 17 8 mm und der maximale Durchmesser 40 mm. Die Tiefe der Ausnehmung kann von wenigen zehntel Millimetern bis hin zu einer Durchgangsbohrung reichen. Wichtig ist, dass ein elastisches Verhalten der zu klemmenden Bauteile möglich ist und über die Ausnehmung 17 die Druckspitze vermieden wird. The size of the recess 17 in diameter or clear width should at least equal to the diameter of the screw 6, but at most five times the diameter. For a set screw 6 with the thread M8 so that the minimum diameter of the recess 17 8 mm and the maximum diameter 40 mm. The depth of the recess can range from a few tenths of a millimeter to a through hole. It is important that an elastic behavior of the components to be clamped is possible and the pressure peak is avoided via the recess 17.
Mit der erfindungsgemäßen Klemmverbindung kann bei vorhandenen Abmessungen ein höheres Türgewicht realisiert werden, indem durch Austauschen ein geänderter Glasschutz 15, eine geänderte Klemmplatte 8 verwendet werden oder durch Nacharbeiten die Seitenwangen 16 ange- passt werden. Dabei ist es nicht nötig, die Rollenwagen 4 und die Laufschiene umzukonstruieren und zu verstärken. Weiterhin kann dadurch auf einen dritten Rollenwagen bzw. ein drittes Band verzichtet werden. Durch die Reduzierung der Spannungsspitzen wird die Glasscheibe 3 sicher gehalten und ein Absacken bzw. Zerstören der Glasscheibe 3 vermieden. Bei gleichen Abmessungen der Rollenwagen 4 und Laufschiene lässt sich das Türgewicht von 100 kg auf 150 kg erhöhen, womit dickere Glasscheiben 3 verwendet werden können. Bezugszeichenliste With the clamping connection according to the invention, a higher door weight can be realized with existing dimensions, by exchanging a modified glass guard 15, a modified clamping plate 8 are used or by reworking the side cheeks 16 adapted. It is not necessary to rebuild the roller carriage 4 and the track and strengthen. Furthermore, this can be dispensed with a third roller carriage or a third band. By reducing the voltage peaks, the glass pane 3 is held securely and slumping or destruction of the glass pane 3 is avoided. With the same dimensions of the roller carriage 4 and track rail, the door weight can be increased from 100 kg to 150 kg, so thicker glass sheets 3 can be used. LIST OF REFERENCE NUMBERS
