Von einem solchen Hubtor geht die Erfindung aus mit der
Aufgabenstellung, das Hubtor geeignet zu machen für den Abschluß
einer Toröffnung eines Tiefkühl-Lagerraumes. Diese
Aufgabe wird gelöst durch eine Ausbildung des Hubtores mit
der in Anspruch 1 aufgezählten Merkmalskombination.The invention is based on such a lifting gate with the
Task to make the lifting gate suitable for the conclusion
a gate opening of a deep-freeze storage room. This
The task is solved by training the lifting gate with
the combination of features listed in
Von besonderer Bedeutung ist bei einem Hubtor für den Einsatz
im Tiefkühlbereich, daß es für hohe Öffnungsgeschwindigkeit
im Bereich von 2 m/sec eingerichtet ist, während
die Schließgeschwindigkeit durch Vorschriften der Unfallverhütung
festgelegt ist. Zur Gewährleistung dieser hohen
Öffnungsgeschwindigkeit, wie es die weitere Aufgabe der Erfindung
ist, ist eine Ausbildung des Hubtores mit den zusätzlichen,
in den Ansprüchen 2 bis 7 aufgeführten Merkmalen
vorgesehen.Is of particular importance for a lifting gate for use
in the freezer area that it is for high opening speed
is set up in the range of 2 m / sec while
the closing speed due to accident prevention regulations
is set. To ensure this high
Opening speed as is the further object of the invention
is a design of the lift gate with the additional,
features listed in
So läßt sich das Torblatt bei Verwendung eines Paneels oder von Paneelteilen mit Vakuum-Isolation (Anspruch 2) wegen deren äußerst hohen Wärmedämmwertes, mit sehr geringer Dicke ausführen (bis zu 1/15 herkömmlicher Dicke). Die Verwendung von Gurten als Zugmittel (Anspruch 3) läßt an sich schon gegenüber anderen Zugmitteln eine höhere Wickelgeschwindigkeit zu. Darüber hinaus ergibt sich mit dem Aufwickeln der das Torblatt anhebenden Gurte und dem einhergehenden Abwickeln der das Gegenmoment auf die Wickelwelle einleitenden Gurte eine Veränderung des Übersetzungsverhältnisses mit einem hohen Anfangsmoment, welches zusammen mit dem Motordrehmoment eine hohe Anfangsbeschleunigung und damit das schnelle Öffnen des Hubtores ergibt. Bei auf die Gurtstärke abgestimmter Durchmesser-Bemessung der Wickeltrommeln kann Momentengleichheit an den Wickeltrommeln der das Torblatt haltenden Gurte und der das Gegenmoment einleitenden Gurte in einer Position gegeben sein, in welcher eine aus Sicherheitsgründen vorgeschriebene Notfall-Mindestöffnung des Hubtores erreicht ist, auch wenn die Wickelwelle von ihrem motorischen Antrieb z.B. bei dessen Ausfall abgekuppelt ist. Ein weiteres Anheben des Torblattes ist nur motorisch möglich, wodurch das Abbremsen des Torblattes zum Einfahren in die Endstellung erfolgen kann (Ansprüche 4 und 5).So the door leaf can be used when using a panel or of panel parts with vacuum insulation (claim 2) because their extremely high thermal insulation value, with very low Execute thickness (up to 1/15 conventional thickness). The usage of belts as a traction device (claim 3) per se a higher winding speed compared to other traction devices to. In addition, there is winding the belts lifting the door leaf and the accompanying Unwind the counter torque on the winding shaft introductory straps a change in gear ratio with a high initial moment, which together with the engine torque a high initial acceleration and so that the quick opening of the lifting gate results. At the Belt size coordinated diameter dimensioning of the winding drums can have the same torque on the winding drums the straps holding the door leaf and the one initiating the counter torque Belts must be in one position, in which a minimum emergency opening required for safety reasons of the lifting gate is reached, even if the Winding shaft from its motor drive e.g. at his Failure is uncoupled. Another lift of the door leaf is only possible by motor, which slows down the Door leaf can be made to move into the end position (Claims 4 and 5).
Das Gegenmoment kann ausgeübt werden durch von den Gurten getragene Gegengewichte (Anspruch 4) oder die Gurte zugbelastende Federn (Anspruch 5), wobei sich die Verwendung von Gegengewichten insbesondere für große und entsprechend schwere Torblätter empfiehlt, wogegen die Verwendung von Federn die hohe Anfangsbeschleunigung infolge ihrer hohen Spannung bei niedrigstehendem Torblatt weiter begünstigt.The counter moment can be exerted by the belts counterweights carried (claim 4) or the straps tensile Springs (claim 5), wherein the use of Counterweights especially for large and accordingly recommends heavy door leaves, whereas the use of Cushion the high initial acceleration due to their high Tension is further promoted when the door leaf is low.
Es kann sich empfehlen (Anspruch 7), das Gegenmoment von einem Gegengewicht und einem Federzug gemeinsam aufzubringen.It can be recommended (claim 7), the counter moment of to bring together a counterweight and a balancer.
Obgleich bei Verwendung von Gurten als Zugmittel die nötige Sicherheit gewährleistet werden kann. sind diesbezügliche Bedenken ausgeschlossen, wenn nach einem weiteren Merkmal der Erfindung (Anspruch 8) ein mittig zum Torblatt angeordneter Sicherheitsgurt oder zwei parallel und nahe den Gurten an den Seitenrändern des Torblattes angeordnete Sicherheitsgurte vorgesehen sind. die ohne Spannung oder mit geringer Vorspannung gleichlaufend mit den Gurten auf ihnen zugeordnete Wickeltrommeln auflaufen.Although the necessary when using belts as a traction device Security can be guaranteed. are related Concerns ruled out when looking for another feature of the invention (claim 8) arranged centrally to the door leaf Seat belt or two parallel and close to the belts Seat belts arranged on the side edges of the door leaf are provided. those without tension or with less Preload running in sync with the straps on them assigned winding drums run up.

Kupplung vorgesehen, die im Notfall betätigt über
einen Kettenzug 17 ausgerückt werden kann, so daß die Welle
7 allein unter den einander entgegenwirkenden Drehmomenten
steht, einerseits des vom Gewicht des Torblattes 1 über die
Gurte 13 und die Gurttrommeln 11 ausgeübten Drehmoments und
andererseits des von den Gegengewichten 15 über die Gurte
14 und die Gurttrommeln 12 ausgeübten Drehmoments, wobei
die Bemessung des Gegengewichtes 15, der Gurttrommeln 11
und 12 im Verhältnis zum Gewicht des Torblattes 1 derart
ist. daß die Drehmomente sich bei einer für den Notfall
ausreichenden Mindestöffnung des Hubtores ausgleichen. Mit

ist. Die Sicherheitsgurte 13a sind ohne Spannung mit
dem Torblatt 1 und ihren drehfest mit der Wickelwelle 7
verbundenen Wickeltrommeln 11a verbunden, jedoch könnten
die Sicherheitsgurte 13a auch unter geringer Vorspannung
stehen, wenn deren Wickeltrommeln 11a drehbeweglich zur
Wickelwelle 7 über je eine begrenzt drehelastische Kupplung
mit den Wickeltrommeln 11 verbunden wären. Beim Reißen eines
Gurtes 13 wird das Torblatt 1 von dem benachbarten
Sicherheitsgurt 13a abgefangen.The modification shown in Figure 1B to the embodiment

Eine weitere Abwandlung ist in der Figur 2C dargestellt und
besteht darin, daß zur Ausübung eines Gegendrehmoments zu
dem durch das Gewicht des Torblattes 1 über die Gurte 13
und die Wickeltrommel 11 ausgeübten Drehmoment eine Feder
38 vorgesehen ist. Diese ist von einer Öse 39 am unteren
Ende des Pfostens 6 gehalten und in ein Jochstück 40 einer
losen Rolle 41 eingehängt, die von einer Schlaufe eines
Gurtes 14a getragen ist, wobei der Gurt 14a mit seinem Endtrum
am oberen Ende des Pfostens 6 von einer Klemmplatte 42
gehalten ist, während das andere Trum des Gurtes 14a an der
mit der Wickelwelle 7 drehfest verbundenen Wickeltrommel
12a befestigt ist. Die Federn 38 können anstelle von Gegengewichten
15 oder zusammen mit einem solchen verwendet werden,
wobei jedenfalls die Bedingung gilt, daß ein Drehmomentausgleich
erst gegeben ist, wenn das Torblatt 1 eine
Mindestöffnungshöhe erreicht hat.A further modification is shown in FIG. 2C and
is that to apply a counter torque
