KAISERLICHESIMPERIAL

PATENTAMT.PATENT OFFICE.

Die Überführung des elektrischen Drahtes vom Türpfosten zur Tür war bei den elektrischen Türöffnern bis jetzt stets die Hauptursache zu deren häufigem Versagen. Man hat versucht, dem Draht durch die Form einer Federspirale eine gewisse Elastizität zu geben, die eine größere Nachgiebigkeit des Drahtes beim Türöffnen und -schließen bedingen sollte; man hat weiter versuchsweiseThe transfer of the electric wire from the door jamb to the door was with the electric ones Until now, door openers have always been the main cause of their frequent failure. Tried to shape the wire through to give a spring coil a certain elasticity, which makes it more flexible Wire when opening and closing doors; one has further experimentally

ίο auf Pfosten und Tür je einen Pendelkontakt gesetzt und beide Kontakte mittels Pendelschnur verbunden, jedoch immer wieder traten Bruchstellen infolge Einklemmens usw. ein, die dem elektrischen Strom den Weg zum Türschloß sperrten.ίο one pendulum contact each on the post and door set and both contacts connected by a pendulum cord, but kicked again and again Breakage as a result of entrapment, etc., which the electrical current the way to Locked the door.

Die Erfindung soll diesem Übelstande abhelfen. Sie besteht zur Hauptsache aus zwei mit besonderer Lagerplatte α an der Tür befestigten, parallel gelagerten Zylindern c, inThe invention is intended to remedy this drawback. It mainly consists of two parallel mounted cylinders c, in, which are attached to the door with a special bearing plate α

ao denen Kolben f mit Kolbenstangen d laufen. Diese Kolben stehen unter dem Druck von Spiralfedern e, so daß sie stets selbsttätig in die Zylinder zurückschnellen. Am Ende der Kolbenstangen sind Ketten g befestigt, die ihrerseits nach zwei am Türpfosten auf besonderer Lagerplatte befestigten Klemmschrauben h, i führen, wo sie befestigt sind. Die Befestigungsart bewirkt, daß bei geschlossener Tür die Ketten sich spannen und die Kolben aus den Zylindern herausziehen, während bei geöffneter Tür die Kolben in die Zylinder zurückschnellen ; ein Einklemmen der Ketten zwischen Tür und Pfosten ist dadurch ausgeschlossen. Der elektrische Strom wird nun wie gewöhnlich mittels Leitungsdraht zu den Polklemmen des Türpfostens geführt, von da übernehmen die aus leitendem Metall hergestellten Ketten die Überleitung nach der Tür, wo sie dieselben an Kolben und Zylinder abgeben, welch letztere am andern Ende Klemmschrauben besitzen, an denen wieder Leitungsdraht zur Abzweigung und Weiterleitung nach Schloß und Druckknopf der Tür angeschlossen werden kann. Ein Bruch und damit verbundene Stromunterbrechung ist dabei ausgeschlos-ao which pistons f run with piston rods d . These pistons are under the pressure of spiral springs e, so that they always snap back automatically into the cylinder. At the end of the piston rods chains g are attached, which in turn lead to two clamping screws h, i attached to the door post on a special bearing plate, where they are attached. The type of fastening means that when the door is closed the chains tighten and pull the pistons out of the cylinders, while when the door is open the pistons snap back into the cylinders; This prevents the chains from getting caught between the door and the post. The electric current is now conducted as usual by means of a conductor wire to the pole terminals of the door post, from there the chains made of conductive metal take over the transmission to the door, where they deliver them to the piston and cylinder, which the latter have clamping screws at the other end again wire for branching and forwarding to the lock and push button of the door can be connected. A break and the associated power interruption are excluded.
