Abstract

The stop plate (6) is connected to a drive shaft (8). The plate is also connected with the gate shaft (2) via the stop wheel (3). The plate engages in rotary direction on the stop wheel, by one or more drive cams (9,10) and via return springs (11). The cams engage into grooves (12) of the stop wheel, which also contain the return springs. The recesses (7) in the stop plate, and the collection chambers (14) in the housing section (5a), are quadrant-shaped. ADVANTAGE - Device functions, even when the drive effect from the drive does not any longer act on the gate shaft.

Description

Die Erfindung bezieht sich auf eine Absturzsicherung gemäß dem Oberbegriff des Hauptanspruches.The invention relates to fall protection according to the preamble of the main claim.

In der EP 216 078 B1 wird eine fliehkraftunabhängige Absturzsicherung für Tore od. dgl. beschrieben, bei welcher eine Torsionsfeder vorgesehen ist, die eine Gegenkraft für das zu sichernde Tor schafft. Bricht diese Feder und fällt damit die Gegenkraft für das Tor weg, tritt die Absturzsicherung dadurch ein, daß sich Sperrkörper in entsprechenden Ausnehmungen im feststehenden Gehäuse verrasten.EP 216 078 B1 describes a centrifugal force independent Fall protection for gates or the like described, at which is provided a torsion spring, the one Creates counterforce for the gate to be secured. Breaks this spring and thus falls the counterforce for that If the gate is gone, the fall protection system is activated by locking body in corresponding recesses in the lock the stationary housing.

Der Erfindung liegt die Aufgabe zugrunde, die gat­ tungsbildende Vorrichtung so auszubilden, daß eine Absturzsicherung geschaffen wird, die in Funktion tritt, wenn der von der Antriebseinrichtung auf die Torwelle ausgeübte Antrieb nicht mehr auf die Tor­ welle wirkt.The invention has for its object the gat tion-forming device so that a Fall protection is created that works occurs when the drive device on the Gate shaft drive no longer exerted on the gate wave works.

Diese der Erfindung zugrundeliegende Aufgabe wird durch die Lehre des Hauptanspruches gelöst.This object underlying the invention will solved by the teaching of the main claim.

Vorteilhafte Ausgestaltungen sind in den Unteran­ sprüchen erläutert.Advantageous configurations are in the Unteran sayings explained.

Mit anderen Worten ausgedrückt wird so vorgegangen, daß der eigentliche Sperrteller mit der Antriebs­ einrichtung in treibender Verbindung steht, wobei der Antrieb in beiden Richtungen möglich ist. Hier­ durch kommt es zu einer Verdrehung zwischen Sperr­ teller und Sperrad unter Zwischenschaltung ent­ sprechender Rückstellfedern bis zu einem festen Anschlag, und zwar dann, wenn das Sperrad in Gegen­ richtung belastet wird. In diesem Zustand schließt der Sperrteller die Aufnahmeräume des Sperrades und die Sperrkörper können nicht austreten und sie be­ finden sich in Ruhestellung in der an sich rotieren­ den Einheit. Dieses so erreichte Zusammenwirken läßt den Freilauf der rotierenden Einheit aus Sperrteller und Sperrad zu. Bei Unterbrechung der Antriebskraft am Sperrteller wird dieser durch die Rückstell­ federn in eine Freigabestellung der Sperrkörper ge­ bracht, und z. B. einige der Sperrkörper können in den entsprechenden Fangkammern im Gehäuse in die Fangstellung eintreten.In other words, that the actual locking plate with the drive device is in driving connection, wherein the drive is possible in both directions. Here  this causes a twist between the lock plate and ratchet wheel with interposition speaking return springs up to a fixed one Stop, and that when the ratchet in counter direction is charged. Closes in this state the locking plate the receiving spaces of the locking wheel and the locking body can not escape and be can be found at rest in the rotate itself the unity. This cooperation thus achieved the freewheel of the rotating unit from the locking plate and ratchet wheel too. When the drive power is interrupted on the locking plate this is reset springs ge in a release position of the locking body brings, and z. B. some of the locking bodies can be in the corresponding capture chambers in the housing Enter the catch position.

Ein Ausführungsbeispiel der Erfindung wird nachfol­ gend anhand der Zeichnungen erläutert. Die Zeich­ nungen zeigen dabei inAn embodiment of the invention will follow explained with reference to the drawings. The drawing The names show in

Fig. 1 in einer auseinandergezogenen Dar­ stellungsweise die verschiedenen Bau­ teile der Absturzsicherung, in Fig. 1 in an exploded Dar the different construction parts of the fall protection, in

Fig. 2 eine teilweise geschnittene Ansicht gemäß der Linie 2-2 in Fig. 3 und in Fig. 2 is a partially sectioned view along the line 2-2 in Fig. 3 and in

Fig. 3 eine Schnittdarstellung entsprechend der Linie 3-3 in Fig. 2. Fig. 3 is a sectional view taken along the line 3-3 in FIG. 2.

Die Absturzsicherung besteht im wesentlichen aus einem Gehäuse 5, wobei in Fig. 1 die beiden Gehäuse­ hälften 5a und 5b dargestellt sind, die - wie dies Fig. 3 zeigt - miteinander verbunden werden können, wobei dann das Gehäuse 5 ortsfest verankert wird. The fall protection essentially consists of a housing 5 , the two housing halves 5 a and 5 b being shown in FIG. 1, which - as shown in FIG. 3 - can be connected to one another, the housing 5 then being anchored in place.

Innerhalb des Gehäuses ist ein Sperrad 3 gelagert, das drehfest mit einer Torwelle 2 verbunden ist, wobei das Sperrad 3 Aufnahmeräume 4 für Sperrkörper 1 aufweist. In der Darstellung sind die Sperr­ körper 1 als Kugeln ausgebildet. Die Auf­ nahmeräume 4 sind in radialer Richtung nach außen offen.A ratchet wheel 3 is mounted within the housing and is connected in a rotationally fixed manner to a gate shaft 2 , the ratchet wheel 3 having receiving spaces 4 for blocking bodies 1 . In the illustration, the locking body 1 are designed as balls. On the receiving rooms 4 are open in the radial direction to the outside.

Drehfest mit einer Antriebswelle 8 ist ein Sperr­ teller 6 verbunden, der das Sperrad 3 übergreift und der in seinem Randbereich mit Ausnehmungen 7 ver­ sehen ist, die viertelkugelförmig ausgebildet sind.A locking plate 6 is connected in a rotationally fixed manner to a drive shaft 8 , which engages over the ratchet wheel 3 and which is seen in its edge region with recesses 7 , which are quarter-spherical.

In der Gehäusehälfte 5a sind im unteren Bereich Fangkammern 14 ausgenommen, die ebenfalls viertel­ kugelförmig ausgebildet sind und die im Zusammen­ wirken mit den viertelkugelförmigen Ausnehmungen 7 im Sperrteller 6 eine halbkugelförmige Ausnehmung zur Aufnahme einer Sperrkugel 1 bilden können.In the housing half 5 a capture chambers 14 are excluded in the lower region, which are also quarter-spherical and which, in cooperation with the quarter-spherical recesses 7 in the locking plate 6 , can form a hemispherical recess for receiving a locking ball 1 .

Der angetriebene Sperrteller 6, der in der Gehäuse­ hälfte 5b gelagert ist, ist antriebsmäßig mit dem Sperrad 3 dadurch verbunden, daß auf der Innenfläche des Sperrtellers 6 vorstehende Antriebsnocken 9 und 10 vorgesehen sind, die in entsprechende Nuten 12 des Sperrades 3 eingreifen können, wobei in den Nuten 12 des Sperrades 3 weiterhin Rückstellfedern 11 angeordnet sind, von denen in der Darstellung gemäß Fig. 1 nur die Rückstellfeder 11 erkennbar ist. Hieraus ist ersichtlich, daß einerseits der Sperrteller 6 das Sperrad 3 derart übergreift, daß die Sperrkugeln 1 nicht aus dem Sperrad 3 heraus­ treten können, sondern maximal nur in die Aus­ nehmungen 7, und daß die Fangkammern 14 so ange­ ordnet sind, daß dann, wenn die Antriebsnocken 9 und 10 die Rückstellfedern 11 komprimiert haben, so daß dann der Antrieb vom Sperrteller 6 zum Sperrad 3 erfolgt. In diesem Antriebszustand stehen die Ausnehmungen 7 im Sperrteller 6 auf Lücke zu den Fangkammern 14 in der Gehäusehälfte 5a und auf Lücke zu den Ausnehmungen 7 im Sperrteller 6, so daß ein Eintreten der Sperrkugeln 1 nicht möglich ist.The driven locking plate 6 , which is mounted in the housing half 5 b, is drivingly connected to the ratchet wheel 3 in that projecting drive cams 9 and 10 are provided on the inner surface of the locking plate 6 , which can engage in corresponding grooves 12 of the ratchet wheel 3 , wherein in the grooves 12 of the ratchet wheel 3 return springs 11 are further arranged, of which only the return spring 11 can be seen in the illustration according to FIG. 1. From this it can be seen that on the one hand the locking plate 6 overlaps the ratchet wheel 3 in such a way that the ratchet balls 1 cannot come out of the ratchet wheel 3 , but at most only in the recesses 7 , and that the catch chambers 14 are arranged so that if the drive cams 9 and 10 have compressed the return springs 11 so that the drive from the locking plate 6 to the locking wheel 3 then takes place. In this drive state, the recesses 7 in the locking plate 6 are at a gap to the catch chambers 14 in the housing half 5 a and at a gap to the recesses 7 in the locking plate 6 , so that the locking balls 1 cannot enter.

In diesem Zustand ist somit eine antriebsmäßige Verbindung zwischen der Antriebswelle 8 und der Tor­ welle 2 möglich, aber ein Einrasten der Sperrkugeln 1 in die Fangkammer 14 ausgeschlossen. In diesem Antriebszustand schließt der Sperrteller 6 die Aufnahmeräume 4 des Sperrades 3 ab, so daß die Sperrkörper 1 nicht austreten können, d. h. sie be­ finden sich in Ruhestellung, und die Einheit aus Sperrteller 6 und Sperrad 3 rotiert.In this state, a drive connection between the drive shaft 8 and the gate shaft 2 is possible, but a locking of the locking balls 1 in the capture chamber 14 is excluded. In this drive state, the locking plate 6 closes the receiving spaces 4 of the locking wheel 3 , so that the locking body 1 cannot emerge, ie they are in the rest position, and the unit consisting of locking plate 6 and locking wheel 3 rotates.

Bei Ausfall der Antriebskraft am Sperrteller 6, das heißt also an der Antriebswelle 8, wird der Sperrteller 6 unter der Wirkung der Rückstellfedern 12 gegenüber den Aufnahmeräumen 4 des Sperrades 3 zurückgedreht, so daß nunmehr eine Freigabestellung der Sperrkugeln 1 eintritt, so daß dann die Sperr­ kugeln 1 in die Ausnehmung 7 und die Fangkammer 14 eintreten können, so daß eine weitere Verdrehung der Torwelle 2 gegenüber der Antriebswelle 8 nicht mehr möglich ist.If the drive force fails on the locking plate 6 , that is to say on the drive shaft 8 , the locking plate 6 is rotated under the action of the return springs 12 relative to the receiving spaces 4 of the locking wheel 3 , so that a release position of the locking balls 1 now occurs, so that the locking mechanism then occurs balls 1 can enter the recess 7 and the catch chamber 14 , so that a further rotation of the gate shaft 2 relative to the drive shaft 8 is no longer possible.
