Description
Die Erfindung betrifft eine Schiebetürschließeinrichtung, bei der das Türblatt mit einem Rollenlaufwerk an einer Trag- und Führungsschiene aufgehängt ist, die eine Rast in Schließstellung des Türblattes aufweist, in die das Türblatt nur unter Aufladung eines Kraftspeichers durch das Rollenlaufwerk überführbar ist und aus der es in die Öffnungsstellung nur unter Entladung des Kraftspeichers überführbar ist.The invention relates to a sliding door locking device, where the door leaf with a roller drive on one Carrier and guide rail is suspended, which has a rest has in the closed position of the door leaf, in which the Door leaf can only be charged with an energy accumulator the roller drive is transferable and from which it into the Open position only when the energy accumulator is discharged is transferable.
Schiebetürschließeinrichtungen dieser Art sind in vielfacher Ausführung bekannt. In vielen Fällen kommt es nicht nur darauf an, daß das Türblatt die Türöffnung abdeckt, sondern sie auch möglichst dicht verschließt. Diese Forderung könnte durch einen Riegelmechanismus erfüllt werden, der das Türblatt in Schließstellung dicht gegen die Türöffnung zieht. Solche Türschließeinrichtungen sind wegen ihrer umständlichen Bedienung für viele Fälle der Praxis ungeeignet. Bei Schiebetürschließeinrichtungen von begehbaren und befahrbaren Kühlräumen, Kühlhäusern, Lagerhallen usw. wird in der Regel erwartet, daß sie sich ohne Kraftaufwand schnell öffnen und schließen lassen, wobei in Schließstellung die Tür möglichst dicht sein soll. Der Kraftaufwand zum Öffnen der bekannten, in Schließstellung befindlichen Schiebetürschließeinrichtung der eingangs genannten Art (DT 26 16 495 A1) ist vergleichsweise gering, weil der sich beim Öffnen entladende Kraftspeicher unterstützend wirkt. Eine optimale Unterstützung ist dabei allerdings nicht gegeben, weil der Kraftspeicher nur parallel zur Führungsschiene wirkt. Um die Tür zu öffnen, muß sie jedoch aus ihrer eingerasteten tiefsten Stellung heraus auch angehoben werden.Sliding door locking devices of this type are in multiple execution known. In many cases it happens not just insist that the door leaf open the door covers, but also seals them as tightly as possible. This requirement could be achieved by a locking mechanism be met, the door leaf tight in the closed position pulls against the door opening. Such Door locking devices are because of their cumbersome Operation unsuitable for many practical cases. At Sliding door locking devices from walk-in and accessible cold rooms, cold stores, warehouses etc. is usually expected to be without Force open and close quickly, whereby in the closed position the door should be as tight as possible. The Force to open the known, in the closed position located sliding door locking device of the beginning mentioned type (DT 26 16 495 A1) is comparative low because of the discharge when opening Lift mechanism has a supporting effect. An optimal one However, there is no support because the energy accumulator only acts parallel to the guide rail. To open the door, however, it must be out of hers engaged lowest position also raised become.
Der Erfindung liegt die Aufgabe zugrunde, eine Schiebetürschließeinrichtung der eingangs genannten Art zu schaffen, bei der der beim Schließen der Tür aufgeladene Kraftspeicher das Öffnen der Tür optimal unterstützt.The invention has for its object a Sliding door locking device of the type mentioned to create where the door closes charged energy store opening the door optimally supported.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Kraftrichtung, in welcher der Kraftspeicher auf das Rollenlaufwerk wirkt, mit der Öffnungsrichtung des Türblattes vor allem zu Beginn der Öffnungsbewegung im wesentlichen übereinstimmt. Besonders vorteilhaft ist es, wenn die Kraft dabei über einen Hebel auf das Rollenlaufwerk übertragen wird. In diesem Fall kann die Bewegungsbahn des Abstützpunkts des Rollenlaufwerks am Hebel durch Lagerung des Hebels so gestaltet sein, daß der Abstützpunkt der Bewegung des Türblatts aus der Rast heraus folgt. Dies läßt sich auf einfache Art und Weise durch die Lage des Schwenklagers des Hebels verwirklichen.This object is achieved in that the direction of force in which the energy accumulator acts on the roller drive with the Opening direction of the door leaf especially at the beginning of the Opening movement essentially coincides. Especially It is advantageous if the force is via a lever is transferred to the roller drive. In this case can the trajectory of the support point of the Roller drive on the lever by mounting the lever so be designed so that the base of the movement of the Door leaf from the rest follows. This can be said simple way due to the location of the pivot bearing of the lever.
Vorzugsweise besteht die Trag- und Führungsschiene aus einer einseitig zur Türöffnung abfallenden Flanke, in der die Rast als Mulde ausgebildet ist, während die Rolle des Rollenlaufwerks eine keilförmige Führungsrille hat. Durch diese Ausgestaltung wird erreicht, daß das Türblatt bei der Überführung in die Schließstellung sowohl in Richtung der Türöffnung bewegt als auch in Richtung des Bodens abgesenkt wird. Diese räumliche Verlagerung des Türblatts hat beim Öffnen den weiteren Effekt, daß schon nach einem sehr kurzen Weg des Türblatts seine Reibung mit der Türöffnung aufgehoben wird und damit das Öffnen erleichtert wird. Der Kraftspeicher kann eine Feder sein. Vorzugsweise ist die wirksame Federkraft einstellbar. The support and guide rail preferably consists of a flank falling on one side to the door opening, in which the rest is designed as a trough, while the role of Roller drive has a wedge-shaped guide groove. By this configuration is achieved in that the door leaf the transfer to the closed position both in the direction the door opening moves as well towards the floor is lowered. This spatial shift of the door leaf has the further effect when opening that after one very short path of the door leaf its friction with the Door opening is canceled and thus the opening is facilitated. The energy accumulator can be a spring. The effective spring force is preferably adjustable.
Im folgenden wird die Erfindung anhand einer Zeichnung näher erläutert. Im einzelnen zeigen:In the following the invention with reference to a drawing explained in more detail. In detail show:

Fig. 5 ein Detail 2 der Schiebetürschließeinrichtung nach Fig. 1 und Fig. 5 shows a detail 2 of the sliding door locking device according to Fig. 1 and
Fig. 6 eine Rastmulde mit Laufrolle der Schiebetürschließeinrichtung gemäß Fig. 1. Fig. 6 is a latching hollow roller with the sliding door closing device of FIG. 1.
Eine Türöffnung 1 mit Rahmen 2 in einem Bauwerk 3 soll mit dem Türblatt 4 einer Schiebetür 5 dicht verschlossen werden. Dazu ist das Türblatt 4 der Schiebetür 5 mit zwei gleichartigen Rollenlaufwerken 6, 7 an einer am Bauwerk 3 befestigten Trag- und Führungsschiene 8 aufgehängt.A door opening 1 with a frame 2 in a building 3 is to be sealed with the door leaf 4 of a sliding door 5 . For this purpose, the door leaf 4 of the sliding door 5 is suspended with two similar roller drives 6 , 7 on a support and guide rail 8 fastened to the structure 3 .
Die Trag- und Führungsschiene 8 weist einen vertikalen Schenkel 8a mit einer im oberen Bereich nach außen abgeknickten Flanke 8b auf. Auf dieser abgeknickten Flanke 8 laufen die Laufrollen 9, 10 der Rollenlaufwerke 6, 7. Die Laufrollen 9, 10 haben eine keilförmige Führungsrille, so daß sie sich mit ihrer der Türöffnung 1 zugewandten Flanke an der abgeknickten Flanke 8b der Trag- und Führungsschiene 8 abstützen, wobei in Öffnungsstellung des Türblattes der Scheitel der Flanke 8b der Trag- und Führungsschiene 8 im Grund der Laufrollen 9, 10 liegt.The support and guide rail 8 has a vertical leg 8 a with a flank 8 b bent outwards in the upper region. The rollers 9 , 10 of the roller drives 6 , 7 run on this bent flank 8 . The rollers 9 , 10 have a wedge-shaped guide groove, so that they are supported with their flank facing the door opening 1 on the bent flank 8 b of the support and guide rail 8 , the apex of the flank 8 b of the support and in the open position of the door leaf Guide rail 8 is in the base of the rollers 9 , 10 .
Die Trag- und Führungsschiene 8 weist für jedes Rollenlaufwerk 6, 7 eine Rastmulde 8b1 an der Stelle auf, an der sich die Laufrollen 9, 10 in der Schließstellung des Türblattes 4 befinden. Diese Stellung ist in Fig. 4 und 6 dargestellt. Die Rastmulde 8b1 in Verbindung mit der abfallenden Flanke 8a bewirkt, daß das Türblatt 4 bei der Bewegung aus der Öffnungsstellung in die Schließstellung sowohl in Richtung der Türöffnung 1 bewegt als auch abgesenkt wird. Auf diese Art und Weise läßt sich das Türblatt 4 dicht an den Rahmen 2 der Türöffnung 1 und den Boden drücken.The support and guide rail 8 has for each roller drive 6, 7 on a latching trough 8 at the point b1, the rollers 9, 10 are in the in the closed position of the door leaf. 4 This position is shown in FIGS. 4 and 6. The locking trough 8 b1 in connection with the falling flank 8 a causes the door leaf 4 to be moved as well as lowered in the direction of the door opening 1 during the movement from the open position into the closed position. In this way, the door leaf 4 can be pressed close to the frame 2 of the door opening 1 and the floor.
Im Weg der Rollenlaufwerke 6, 7 im Schließbereich ist je ein Kraftspeicher angeordnet, der aus einer Feder 11, 12 besteht. Die eingesetzte Feder 11, 12 wird nach der gewünschten Hilfskraft dimensioniert. Mit einer Gewindestange kann eine Feinjustierung vorgenommen werden. Die Feder 11, 12 belastet einen Hebelarm 13, 14. Beim Bewegen des Türblattes 4 in Schließrichtung schlägt das Rollenlaufwerk 6, 7 mit einem Mitnehmer 6a an den Hebel 13, 14 an und verschwenkt ihn unter Spannen der Feder 11, 12. Das Spannen der Feder 11, 12 wird durch das Einrasten der Laufrolle 9, 10 in die Rastmulde 8b1 erleichtert. Umgekehrt wird das Öffnen des Türblattes 4 erleichtert, weil dabei die Kraft der Feder 11, 12 auf das Rollenlaufwerk 6, 7 in Öffnungsrichtung wirkt. Die Bewegungsrichtung des Hebels 13, 14 kann dabei durch dessen Lage so eingestellt werden, daß sie mit der Bewegungsrichtung des Laufwerkes 6, 7 bezüglich der Richtungskomponenten nach oben und von der Türöffnung 1 weg übereinstimmt.In the path of the roller drives 6 , 7 in the closing area, an energy store is arranged, which consists of a spring 11 , 12 . The spring 11 , 12 used is dimensioned according to the desired auxiliary force. A fine adjustment can be made with a threaded rod. The spring 11 , 12 loads a lever arm 13 , 14 . When moving the door leaf 4 in the closing direction, the roller drive 6 , 7 strikes with a driver 6 a on the lever 13 , 14 and pivots it by tensioning the spring 11 , 12 . The tensioning of the spring 11 , 12 is facilitated by the engagement of the roller 9 , 10 in the locking recess 8 b1. Conversely, opening the door leaf 4 is facilitated because the force of the spring 11 , 12 acts on the roller drive 6 , 7 in the opening direction. The direction of movement of the lever 13 , 14 can be adjusted by its position so that it corresponds to the direction of movement of the drive 6 , 7 with respect to the directional components upwards and away from the door opening 1 .
