Description

Die vorliegende Erfindung betrifft eine Schiebetür für Gefrier-, Kühl- oder Betriebsräume, bei denen eine Abdichtung im Schließzustand notwendig oder wünschenswert ist, wobei die Schiebetür einen gebäudeseitig festlegbaren Rahmen, ein Türblatt und eine obere Laufschiene umfasst und die Führungsschiene etwa im Bereich der vertikalen Holme des Türrahmens Führungsabschnitte zur Absenkung und zum Anrücken des Türblattes an den Rahmen aufweist.The present invention relates to a sliding door for freezing, refrigerating or operating rooms, in which a seal in the closed state is necessary or desirable, wherein the sliding door comprises a building side fixable frame, a door leaf and an upper running rail and the guide rail approximately in the region of the vertical spars the door frame has guide portions for lowering and for advancing the door leaf to the frame.

Schiebetüren der vorerwähnten Art sind in vielerlei Ausführungsformen bekannt.Sliding doors of the aforementioned type are known in many embodiments.

Schiebetüren der vorerwähnten Art sind beispielsweise aus der DE 297 02 221 U1 und der DE 197 25 355 A1 bekannt.Sliding doors of the aforementioned type are for example from the DE 297 02 221 U1 and the DE 197 25 355 A1 known.

Grundsätzlich ist bei derartigen Schiebetüren vorgesehen, dass Türblatt in der Weise zu führen, dass in dessen Schließstellung eine Abdichtung sowohl gegenüber dem gebäudeseitig festgelegten Rahmen wie auch gegenüber dem Fußboden gewährleistet ist und dass das Türblatt aus dieser Schließstellung heraus über eine relativ geringe Verschiebestrecke einerseits gegenüber dem Boden etwas angehoben und andererseits gegenüber der Ebene des Türrahmens etwas abgerückt wird, so dass nun das Türblatt frei in seine Öffnungsstellung verschoben werden kann und umgekehrt wird das Türblatt kurz vor Erreichen der endgültigen Schließstellung durch die entsprechenden Führungen wieder an den Rahmen angerückt und auf den Boden abgesenkt.Basically, it is provided in such sliding doors that lead door leaf in such a way that in the closed position, a seal is guaranteed both towards the building side fixed frame as well as to the floor and that the door leaf from this closed position over a relatively small displacement distance on the one hand Floor slightly raised and on the other hand slightly away from the plane of the door frame, so that now the door leaf can be moved freely in its open position and conversely, the door leaf is moved back shortly before reaching the final closed position by the corresponding guides to the frame and lowered to the ground.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine Schiebetür der gattungsgemäßen Art zu schaffen, die sich durch eine kostengünstige und trotzdem absolut praxisgerechte Konstruktion auszeichnet.The present invention has for its object to provide a sliding door of the generic type, which is characterized by a cost-effective, yet absolutely practical design.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass die Laufschiene durch den oberen Querholm des Rahmens und durch ein über den Rahmen seitlich hinaus vorstehendes Verlängerungsprofil vollständig gebildet wird.This object is achieved in that the running rail is completely formed by the upper cross member of the frame and by an over the frame laterally projecting extension profile.

Durch diese Maßnahme wird eine beträchtliche Kosteneinsparung erzielt, da bislang die komplette Laufschiene ein separates Bauteil oder eine separate Baugruppe mit entsprechend hohen und zusätzlichen Fertigungskosten war. Diese zusätzlichen Fertigungskosten entfallen nun weitestgehend, ohne die Funktion bzw. den Nutzen der Schiebetür negativ zu beeinträchtigen.By this measure, a considerable cost saving is achieved, since so far the complete track was a separate component or a separate module with correspondingly high and additional manufacturing costs. These additional manufacturing costs are now largely eliminated, without negatively affecting the function or the benefits of the sliding door.

Weitere Merkmale der Erfindung sind Gegenstand von Unteransprüchen.Further features of the invention are the subject of dependent claims.

Ein Ausführungsbeispiel der Erfindung ist in den beigefügten Zeichnungen dargestellt und wird im Folgenden näher beschrieben.An embodiment of the invention is illustrated in the accompanying drawings and will be described in more detail below.

In den Figuren 1 bis 3 ist eine Schiebetür 1 für Gefrier-, Kühl- oder Betriebsräume gezeigt, die im Wesentlichen aus einem gebäudeseitig festlegbaren Rahmen 2, einer oberen Laufschiene 3 und einem Türblatt 4 besteht, welches längs der oberen Laufschiene 3 aus einer Schließstellung heraus in eine Öffnungsstellung verschiebbar ist. In den Figuren 1 bis 3 ist das Türblatt 4 in seiner Schließstellung gezeigt.In the FIGS. 1 to 3 a sliding door 1 for freezing, cooling or operating rooms is shown, which consists essentially of a building side fixable frame 2, an upper track 3 and a door leaf 4, which is displaceable along the upper track 3 from a closed position into an open position. In the FIGS. 1 to 3 the door leaf 4 is shown in its closed position.

Zu seiner Betätigung ist das Türblatt 4 dargestellten Ausführungsbeispiel beidseitig mit Griffmulden 5 ausgestattet, alternativ hierzu besteht aber auch die Möglichkeit, zur Betätigung des Türblattes 4 eine Handhabe in Form eines Hebels 6 vorzusehen, wie dies in Figur 4 andeutungsweise gezeigt ist.For its operation, the door leaf 4 illustrated embodiment is equipped on both sides with recessed grips 5, alternatively, there is also the possibility to provide for actuating the door leaf 4, a handle in the form of a lever 6, as in FIG. 4 is shown hinted.

Die Laufschiene 3, längs derer das Türblatt 4 verschiebbar geführt ist, wird durch den oberen Holm 7 des Rahmens 2 sowie durch ein über den Rahmen 2 seitlich hinaus vorstehendes Verlängerungsprofil 7 a gebildet, welches grundsätzlich einstückig mit dem oberen Holm 7 des Rahmens 2 gefertigt sein kann, vorzugsweise aber als separates Bauteil lösbar mit dem oberen Holm 7 des Rahmens 2 verbunden ist. Die Verbindung zwischen dem oberen Holm 7 und dem Verlängerungsprofil 7 a wird weiter unten noch ausführlich erläutert.The running rail 3, along which the door leaf 4 is slidably guided, is formed by the upper spar 7 of the frame 2 and by an over the frame 2 laterally projecting extension profile 7 a, which are basically made in one piece with the upper spar 7 of the frame 2 can, but preferably as a separate component is detachably connected to the upper spar 7 of the frame 2. The connection between the upper spar 7 and the extension profile 7 a will be explained in more detail below.

Die Laufschiene 3 ist an sich bekannter Weise etwa im Bereich der vertikalen Holme 8 des Rahmens 2 mit Führungsabschnitten versehen, längs derer das Türblatt 4 kurz vor Erreichen der endgültigen Schließposition zum Boden hin abgesenkt und an den Rahmen 2 angerückt wird, so dass sich eine abdichtende Schließstellung zwischen dem Türblatt 4, dem Rahmen 2 und dem Boden ergibt, wobei hier selbstverständlich entsprechende Dichtungen am Türblatt 4 vorgesehenen sind, die in Schließstellung sowohl am Rahmen 2 wie auch bodenseitig anliegen. Beim Öffnen des Türblattes 4 wird entsprechend der bekannten Führungsabschnitte das Türblatt zunächst wieder vom Boden abgehoben und vom Rahmen 2 abgerückt, so dass nunmehr die Dichtungen keinen Kontakt mehr mit dem Rahmen bzw. dem Boden haben und eine ungehinderte Verschiebung des Türblattes 4 möglich ist. Da diese Funktionsweise prinzipiell bekannt ist, ist hier auf eine detaillierte Darstellung dieser Führungsabschnitte im Bereich der Laufschiene 3 verzichtet worden.The running rail 3 is provided in a known manner approximately in the region of the vertical bars 8 of the frame 2 with guide portions along which the door leaf 4 is lowered shortly before reaching the final closed position to the ground and moved to the frame 2, so that a sealing Closed position between the door leaf 4, the frame 2 and the bottom results, in which case, of course, appropriate seals are provided on the door leaf 4, which rest in the closed position both on the frame 2 as well as the bottom side. When opening the door leaf 4, the door leaf is first lifted back from the ground and moved away from the frame 2 according to the known guide sections, so that now the seals no longer have contact with the frame or the floor and an unobstructed displacement of the door leaf 4 is possible. Since this mode of operation is known in principle, a detailed description of these guide sections in the region of the running rail 3 has been dispensed with here.

Zusätzlich zur oberen Laufschiene 3 ist im unteren Endbereich der Schiebetür 1 - aber deutlich oberhalb des Bodens- eine untere Führungsschiene 9 vorgesehen, die ebenfalls gebäudeseitig festlegbar ist. In diese untere Führungsschiene 9 greift ein Führungskörper in Form einer Führungsrolle 10 ein, wie die Figuren 6 und 12 deutlich machen. Diese Führungsrolle 10 ist an einem mit dem Türblatt 4 fest verbundenen Lagerbock 11 montiert. Die Kontur der untern Führungsschiene 9 ist so gewählt, dass auch der untere Bereich des Türblattes 4 kurz vor Erreichen der endgültigen Schließstellung an den Rahmen 2 angerückt wird, was Figur 6 besonders deutlich zeigt.In addition to the upper running rail 3, a lower guide rail 9 is provided in the lower end region of the sliding door 1, but clearly above the floor, which is likewise fixable on the building side. In this lower guide rail 9 engages a guide body in the form of a guide roller 10, as the FIGS. 6 and 12 make clear. This guide roller 10 is mounted on a fixedly connected to the door leaf 4 bearing block 11. The contour of the lower guide rail 9 is chosen so that even the lower portion of the door leaf 4 is moved shortly before reaching the final closed position on the frame 2, which FIG. 6 shows very clearly.

Durch die Laufschienen 3 und die Führungsschiene 9 wird somit das Türblatt 4 kurz vor Erreichen der endgültigen Schließstellung an den Rahmen 2 heranbewegt und auf den Boden abgesenkt. Hierdurch ergibt sich die schon weiter oben angesprochene umlaufende Abdichtung entsprechend den Anforderungen an Schiebetüren für Gefrierräume, Kühlräume oder andere Betriebsräume.By the rails 3 and the guide rail 9 thus the door leaf 4 is moved up shortly before reaching the final closed position to the frame 2 and lowered to the ground. This results in the above-mentioned circumferential seal according to the requirements of sliding doors for freezers, cold rooms or other operating rooms.

Damit das Türblatt 4 in dieser Schließstellung auch in dem der unteren Führungsschiene 9 gegenüberliegenden stirnseitigen Bereich in die Stellung fixiert ist, ist an dem betreffenden vertikalen Holm 8 ein gegenüber der Ebene des Türrahmens 2 geneigt verlaufender Halter 12 und ein hiermit zusammenwirkender, am Türblatt 4 stirnseitig angebrachter Riegel 13 vorgesehen, welcher in Schließstellung den Halter 12 hintergreift und ein Anpressen des Türblattes 4 an den entsprechenden vertikalen Holm 8 des Rahmens 2 bewirkt. Dies ergibt sich insbesondere aus Figur 5 und aus Figur 13. An der Rückseite des Türblattes 4, welches oberseitig über die obere Laufschiene 3 hinaus vorsteht, sind Laufrollen 14 derart befestigt, dass der Abstand der Laufrollen 14 zum Türblatt 4 justierbar bzw. einstellbar ist. Diese Laufrollen 14 stützen sich auf der entsprechend konturierten oberen Längskante der oberen Laufschiene 3 ab, was aus den Figuren 10 und 11 deutlich hervorgeht. Dabei ist in Figur 10 eine Situation gezeigt, die der Schließstellung des Türblattes 4 entspricht, das heißt, in Figur 10 ist der Abstand des Türblattes 4 zum Rahmen 2 geringer als bei der in Figur 11 gezeigten, dem ganz- oder teilweise geöffneten Türblatt 4 entsprechenden Position. Hier ist der Abstand des Türblattes 4 zum Rahmen 2 größer als in Figur 10, so dass nun ein ungehindertes Verschieben des Türblattes 4 längs der Laufschiene 3 möglich ist.Thus, the door leaf 4 is fixed in this closed position in the lower guide rail 9 opposite end face in the position is on the respective vertical beam 8 a relative to the plane of the door frame 2 inclined holder 12 and a hereby cooperating, on the door leaf 4 frontally attached latch 13 is provided, which engages behind the holder 12 in the closed position and causes a pressing of the door leaf 4 to the corresponding vertical spar 8 of the frame 2. This is especially evident FIG. 5 and from FIG. 13 , On the back of the door leaf 4, which protrudes on the upper side beyond the upper running rail 3 addition, rollers 14 are fixed such that the distance of the rollers 14 to the door leaf 4 is adjustable or adjustable. These rollers 14 are based on the correspondingly contoured upper longitudinal edge of the upper running rail 3, which from the Figures 10 and 11 clearly shows. It is in FIG. 10 a situation is shown which corresponds to the closed position of the door leaf 4, that is, in FIG. 10 is the distance of the door leaf 4 to the frame 2 less than in the FIG. 11 shown, the wholly or partially open door leaf 4 corresponding position. Here, the distance of the door leaf 4 to the frame 2 is greater than in FIG. 10 , so that now an unhindered movement of the door leaf 4 along the running rail 3 is possible.

Aus den Figuren 10 und 11 ergibt sich auch, dass an der Rückseite des Türblattes 4 justierbare Sicherungsstifte 15 vorgesehen sind, die in eine Längsnut 16 der Laufschiene hineinragen, um das Herausspringen des Türblattes 4 aus der Führungsposition zu verhindern. Die erwähnten Sicherungsbolzen 15 werden bei der Montage des Türblattes 4 zunächst in Richtung des Türblattes 4 bewegt, um das Türblatt 4 mit seinen Laufrollen 14 ungehindert auf die Laufschiene 3 aufhängen zu können. Danach werden die Sicherungsbolzen 15 in die besagte Sicherungsposition in die Längsnut 16 hereinbewegt.From the Figures 10 and 11 also shows that 4 adjustable locking pins 15 are provided on the back of the door panel, which protrude into a longitudinal groove 16 of the track to prevent the jumping out of the door panel 4 from the leadership position. The aforementioned safety pin 15 are initially moved in the assembly of the door leaf 4 in the direction of the door leaf 4 to hang the door leaf 4 with its rollers 14 unhindered on the running track 3 can. Thereafter, the securing bolts 15 are moved into the said securing position in the longitudinal groove 16.

Der den oberen Rahmenholm bildende Abschnitt der Laufschiene 3 ist mit den vertikalen Holmen stumpf verbunden, was die Figuren 7 und 8 deutlich zeigen. Dabei liegt der angesprochene Bereich der Laufschiene 3 stumpf auf den oberen stirnseitigen Enden der vertikalen Rahmenholme 8 auf und ist durch Ankerschrauben 15 sowie in den vertikalen Rahmenholmen 8 fixierten Gewindestücken 16 mit den vertikalen Rahmenholmen 8 fest, aber lösbar verbunden, wobei durch Passstifte 17 eine exakte Lagesicherung gewährleistet ist.The upper frame rail forming portion of the running rail 3 is butt-connected to the vertical bars, which is the FIGS. 7 and 8th clearly show. In this case, the addressed area of the running rail 3 is blunt on the upper front ends of the vertical frame members 8 and is fixed by anchor bolts 15 and fixed in the vertical frame spars 8 threaded pieces 16 with the vertical frame spars 8, but releasably connected, with an exact by dowel pins 17 Secured position is guaranteed.

Figur 9 zeigt den Verbindungsbereich zwischen dem einen Teil der Laufschiene 3 bildenden oberen Querholm des Rahmens und dem damit verbundenen Verlängerungsprofil 7 a. Es wird deutlich, dass zur exakten Ausrichtung des oberen Querholmes 7 und des Verlängerungsprofiles 7 a Passstifte 17 vorgesehen sind, die in beide Profilabschnitte hineinragen und das die mechanische Verbindung über eine Verschraubung 18 erfolgt. FIG. 9 shows the connection region between the part of the running rail 3 forming upper cross member of the frame and the associated extension profile 7 a. It is clear that for the exact alignment of the upper cross member 7 and the extension profile 7 a dowel pins 17 are provided, which protrude into both profile sections and the mechanical connection via a screw 18.

Die Trennung der gesamten Laufschiene 3 in der dargestellten und beschriebene Weise bietet die Möglichkeit, dass diese bei Versand der Bestandteile einer kompletten Schiebetür 1 platzsparend mit den übrigen Teilen zu einer Verpackungseinheit zusammengefasst werden kann.The separation of the entire track 3 in the illustrated and described manner offers the possibility that this can be summarized in shipping the components of a complete sliding door 1 to save space with the other parts to a packaging unit.

Um den Verschiebeweg des Türplattes 4 in Öffnungsrichtung zu begrenzen, ist an der Laufschiene 3 ein Stopper 19 befestigt, der im Verschiebeweg eines am Türblatt 4 befestigten Anschlages 20 liegt, wodurch der öffnungsseitige Verschiebeweg des Türblattes 4 endgültig begrenzt wird. Zusätzlich ist hier eine einstellbare Bremseinrichtung 21 vorgesehen, die verhindert, dass das Türblatt 4 beim Auftreffen des Anschlages 20 auf den Stopper 19 wieder in Schließrichtung zurückläuft, wobei die Bremskraft gerade so eingestellt werden sollte, dass das Türblatt 4 in seiner vollkommen geöffneten Stellung zwar sicher fixiert ist, die Kräfte zum Schließen des Türblattes 4 aber auch nicht zu groß werden.In order to limit the displacement of the door panel 4 in the opening direction, a stopper 19 is attached to the running rail 3, which is in the displacement of a door attached to the door 4 stop 20, whereby the opening-side displacement of the door leaf 4 is finally limited. In addition, an adjustable braking device 21 is provided here, which prevents the door leaf 4 when hitting the stop 20 back to the stopper 19 back in the closing direction, the braking force should be just adjusted so that the door leaf 4 in its fully open position, although safe is fixed, the forces to close the door panel 4 but not too big.

Das Türblatt 4 kann insgesamt bezüglich seiner Höhenlage relativ zum Boden wie auch in seinem Abstand zum Rahmen 2 in seiner Schließlage so justiert werden, dass sich optimale Anpresskräfte bezüglich der in der Schließstellung wirksamen Dichtungen ergeben.Overall, the door leaf 4 can be adjusted in its closed position with respect to its altitude relative to the ground as well as in its distance from the frame 2, that arise optimum contact forces with respect to the effective in the closed position seals.

Die Justierung der Höhenlage des Türblattes 4 relativ zum Boden kann dabei über eine Höhenverstelleinrichtung 22 erfolgen, wie aus den Figuren 10 und 11 hervor geht.The adjustment of the altitude of the door leaf 4 relative to the ground can be done via a height adjustment device 22, as from the Figures 10 and 11 comes out.

Da die untere Führungsschiene 9 oberhalb des Bodens liegt, besteht die Möglichkeit, eine erfindungsgemäße Schiebetür 1 schon zu montieren, wenn bauseitig die endgültige Bodenkonstruktion noch nicht fertig gestellt ist.Since the lower guide rail 9 is above the floor, it is possible to mount a sliding door 1 according to the invention already when the final floor construction is not completed on site.

Im dargestellten Ausführungsbeispiel ist eine manuelle Betätigung des Türblattes 4 zum Zwecke des Öffnens und Schließen vorgesehen.In the illustrated embodiment, a manual operation of the door leaf 4 is provided for the purpose of opening and closing.

Abweichend hiervon ist es natürlich auch möglich, die Öffnungs- oder Schließbewegung des Türblattes 4 zu automatisieren, das heißt, das Türblatt 4 kann auch über einen Motorantrieb, einen doppelt wirkenden Druckmittel-Zylinder oder dergleichen bewegt werden.Notwithstanding this, it is of course also possible to automate the opening or closing movement of the door leaf 4, that is, the door leaf 4 can also be moved by a motor drive, a double-acting pressure cylinder or the like.

Die Laufschiene 3 besteht vorteilhafter Weise aus einem massiven Kunststoffprofil, unabhängig davon, ob die Laufschiene 3 einstückig gefertigt oder zweiteilig ausgebildet ist.The running rail 3 is advantageously made of a solid plastic profile, regardless of whether the running rail 3 is made in one piece or formed in two parts.
