Description
Die bisher bekannten Verriegelungen für Aufzugtüren, die durch eine bewegliche Gleitbahn am Fahrkorb betätigt werden, bilden dann eine Gefahr, wenn durch einen Schluß in der Leitung oder in den Zwangskontakten derAufzug bei offenerTür in Bewegung gesetzt werden kann.The previously known locks for elevator doors that by a moving slideway on the car are operated, then form a danger if by a short in the line or in the forced contacts of the elevator with the door open can be set in motion.
Diese Möglichkeit wird verhindert, wenn das Schließen der Riegelstromkontakte nur bei geschlossener Tür erfolgen kann. Hierbei ist es wichtig, die Leitungen für die Riegelstromkontakte getrennt von :den Leitungen für Zwangskontakte zu verlegen.This possibility is prevented when the latch current contacts close can only be done with the door closed. Here it is important to have the lines for to lay the latch current contacts separately from: the cables for forced contacts.
Nach :der Erfindung wird bei geschlossener Tür der Sperrbolzen beim Vorschieben in der Tür, vorzugsweise durch eine oder mehrere spiralförmige Nuten und durch entsprechende Zähne in der Türführung, um einen bestimmten Winkel gedreht und dadurch der Riegelstromkontakt geschlossen.According to: the invention with the door closed, the locking bolt at Advance in the door, preferably through one or more spiral grooves and rotated by a certain angle through corresponding teeth in the door guide and thereby the latch current contact is closed.
Wird der Sperrbolzen im Falle einer Störung bei offener oder angelehnter Tür ein Stück vorgeschoben, so kann die Drehung nicht erfolgen, und der Sperrbolzen wird im Gehäuse in einer Lage arretiert, in der der Riegelstromkontakt geöffnet bleibt.If the locking pin is open or ajar in the event of a malfunction The door is pushed forward a little so the rotation cannot take place, and the locking pin is locked in the housing in a position in which the latch current contact opens remain.
Türriegel, welche bei einer Längsverschiebung zusätzlich eine Drehbewegung erhalten, sind bei einem Doppelriegelverschluß für eine Aufzugschachttür bereits bekannt.Door bolt, which in the event of a longitudinal displacement also rotates are already received with a double bolt lock for an elevator shaft door known.
Den schematischen Schließvorgang der Verriegelung zeigt die Zeichnung in drei verschiedenen Stellungen. Stellung I: Verriegelung geschlossen, Stellung II: Verriegelung arretiert, Stellung III: Verriegelung geöffnet.The drawing shows the schematic closing process of the lock in three different positions. Position I: lock closed, position II: lock locked, position III: lock open.
Die bewegliche Gleitbahn gibt vor Fahrtbeginn, also bei geschlossener Tür und Stellung III der Verriegelung, den Rollenhebel q. mit dem Betätigungshebel 3 frei. In die zahnförmigen Rillen des Sperrbolzens :2 greift der an einem Ende verzahnte Betätigungshebel 3 ein, der gleichzeitig die Kontakte 7, 8 und 9 zwangsweise öffnet bzw. schließt.The movable slideway gives before the start of the journey, i.e. when it is closed Door and position III of the lock, the roller lever q. with the operating lever 3 free. In the tooth-shaped grooves of the locking pin: 2 it engages at one end toothed operating lever 3, which at the same time the contacts 7, 8 and 9 forcibly opens or closes.
Wird der Sperrbolzen :2 durch die Druckfeder 6 vorgeschoben und durch die Zähne der Führung i i entsprechend seiner spiralförmigen Nut gedreht, so werden die Riegelstromkontakte 8 und 9 geschlossen, gemäß Stellung I. In der Stellung II wird bei offener Tür io beim Vorschieben der Sperrbolzen :2 nicht gedreht, sondern durch den Arretierungsstift 5 in einer Nut des Gehäuses i festgehalten.If the locking pin: 2 is pushed forward by the compression spring 6 and through the teeth of the guide i i are rotated according to its spiral groove so the latch current contacts 8 and 9 closed, according to position I. In position II When the door is open, the locking bolt: 2 is not turned when it is pushed forward, but held by the locking pin 5 in a groove in the housing i.
Die Riegelstromkontakte 8 und 9 können nicht geschlossen werden.The latch current contacts 8 and 9 cannot be closed.
