Description
Verfahren und Vorrichtung zum Öffnen -und Schließen von Kassettenklappen für Theaterbühnen und ähnliche Zwecke. Die Erfindung betrifft ein Verfahren und Vorrichtung zum öffnen und Schließen von Kassettenklappen für Theaterbühnen und ähnliche Zwecke mittels, eines einerseits an den Klappen und anderseits am Unterbau arge, lenkten Kniehebels. Das Neue besteht darin, daß der Kniehebel zwecks Entriegelung und öffnens der Klappen nach innen und zwecks Schließens und Verriegelung der Klappen nach außen durchgeknickt und in der Verriege(-lungsstellung dadurch gesichert wird, daß einer der Kniehebelarme über das Gelenk verlängert ist und .sich mit einem Anschlag auf den anderen Kniehebelarm legt. Auf diese Weise wird bei einfacher Bauart und Bedienung eine sichere Versperrung der Kassettenklappen in der geschlossenen Stellung gewährleistet.Method and device for opening and closing cassette flaps for theater stages and similar purposes. The invention relates to a method and Device for opening and closing cassette flaps for theater stages and similar purposes by means of one on the one hand on the flaps and on the other hand on the substructure arge, steered toggle lever. The new thing is that the toggle lever is used for unlocking and opening the flaps inward and for closing and locking the flaps bent outwards and secured in the locking position that one of the toggle arms is extended over the joint and .sich with a stop on the other knee lever arm. In this way, with a simple design and Operation a safe locking of the cassette flaps in the closed position guaranteed.
Die Erfindung ist auf der Zeichnung in einem Ausführungsbeispiel in einfachen Linien veranschaulicht, und zwar in Abb. i im verriegelten und in Abb.2 im entriegelten Zustande, während die Abb.3 die Vorrichtung in einer Längsansicht darstellt.The invention is shown in one embodiment in the drawing simple lines illustrated, namely in Fig. i in the locked and in Fig.2 in the unlocked state, while Fig.3 shows the device in a longitudinal view represents.
Zur Abstützung der bei i an den festen Bühnenaufbau angelenkten Kassettenklappe 2 dient der aus den beiden Hebelarmen 3' und 3" bestehende Kniehebel, welcher bei 4. an der Kassettenklappe 2 und bei 5 an dem. festen Gestell angelenkt ist. Die beiden Aime 3' und 3" sind bei 6 aneinandergelenkt, wobei der Arm 3' -über das Gelenk 6 hinaus verlängert und mit einem Anschlag 7 versehen ist, derart, daß in der Riegelstellung (Abb. i) die beiden Arme 3' und 3" des Kniehebels einen stumpfen Winkel miteinander bilden.To support the cassette flap hinged to the fixed stage structure at i 2, the toggle lever consists of the two lever arms 3 'and 3 ", which is used in 4. on the cassette flap 2 and at 5 on the. fixed frame is hinged. the both aime 3 'and 3 "are hinged together at 6, with the arm 3' -over the hinge 6 is also extended and provided with a stop 7, such that in the locking position (Fig. I) the two arms 3 'and 3 "of the toggle lever make an obtuse angle with one another form.
Die Bewegung des Kniehebels zwecks Verriegelung oder Entriegelung der Kassettenklappe kann durch einen Schwinghebel 8 bewirkt werden, der auf der Welle 9 sitzt, die beispielsweise durch eine auf ihr befestigte Kurbel gedreht werden kann.The movement of the knee lever to lock or unlock the cassette flap can be effected by a rocker arm 8, which is on the Shaft 9 sits, which are rotated, for example, by a crank attached to it can.
Der Schwinghebel 8 kann mit einem Führungsschlitz i o schwingartig um einen Stift i i fassen, der am Hebelarm 3" befestigt ist.The rocker arm 8 can swing-like with a guide slot i o to grasp a pin i i attached to the lever arm 3 ".
Falls es erwünscht ist, ,die hintereinander gelegenen Kassettenklappen unabhängig voneinander wahlweise -ent- und verriegeln zu können, so wird nach Abb. 3 der Schwinghebel 8 jedes Kniehebels nicht fest, sondern lose auf der gemeinsamen Welle 9 angeordnet, kann aber mit einem für jedes Hebelpaar 8 fest auf der Welle 9 verkeilten Antriebshebel 14. vermittels eines Durchsteckbolzens 12 gekuppelt werden.If desired, the cassette doors, one behind the other to be able to unlock and lock independently of each other, as shown in Fig. 3 the rocker arm 8 of each toggle lever not fixed, but loosely on the common Shaft 9 arranged, but can be fixed with one for each pair of levers 8 on the shaft 9 wedged drive lever 14 can be coupled by means of a through bolt 12.
