Schlosstechnik, Schlösser, Verschlüsse 1.827 Patente

Zu Ihrem Komfort, sind alle Patentschriften in einer Datenbank mit echtem Patentindex (c). Sie können in allen Titeln suchen, ohne einzelne PDF-Dateien öffnen zu müssen, wie das bei anderen Sammlungen gerne der Fall ist. Sie erhalten hier mehr als nur eine Pateninfo. Sie können aber auch durch ALLE Seiten schnell durchblättern, wenn Sie etwas suchen. Mit weniger sollten Sie sich nicht zufrieden geben.

Lernen Sie die Geheimnisse der Schlossmechanismen kennen. Hier lesen Sie die "State of the Art" Patente von Türschlössern, Autoschlössern, Tresorschlössern und vieles , was es teils noch nicht im Handel gibt. Haben Sie sich noch nie gefragt "Wie funktioniert das?". Hier lesen Sie es. Die Angaben sind sehr detailliert. Ein absolutes Muss für Schlüsseldienste und Entweickler

In den Abbildungen oben sind nur einige Beispiele der sehr detailliert bebilderten und beschriebenen Schlösser und Verfahren. Eine Patentschrift muss so ausführlich beschrieben sein, dass ein technisch Versierter diese nachvollziehen und auch nachbauen kann. Patentschriften sind immer die ersten Veröffentlichungen von Innovationen, oft lang bevor solche Artikel im Handel erhältlich sind. Ausserdem ist diese Patentsammlung ein unergründlicher Pool von innovativen Ideen für die eigene Anwendung (selbstverständlich dürfen diese Produkte in unveränderter Form nur für private, nicht kommerzielle Zwecke nachgebaut werden. Die ausführlich beschriebenen Gedankengänge der Erfinder schulen den eigenen Geist für Ihre vielleicht nächste eigene "Erfindung". Profitieren Sie von diesem Wissensvorsprung.

Normalerweise können es sich nur Firmen leisten umfangreiche Patentrecherchen, wie die hier angebotene, erstellen zu lassen. Die Zusammenstellung solcher Sammlungen in gut archivierbarem Format ist aufwendig und setzt kostenpflichtige Datenbankprogramme voraus. Manche amerikanische Firmen berechnen für die Recherche bis zu 3,50 Dollar pro Patent!

Die meisten Patente weltweit sind in englischer Sprache verfasst. Das ist auch gut so, oder wollen Sie die Ausführungen eines japanischen Erfinders geniessen? Schulkenntnisse in English sind vollkommen ausreichend und die zahlreichen Abbildungen erleichtern den Nachbau und Ihre eigene "Forschung".

Die Zusammenstellung wird auf Originaldatenträgern (CD oder DVD) des Verlages ausgeliefert. Die Seitenangabe in DIN A 4 bezieht sich auf den Ausdruck der Sammlung auf einem DIN A 4 Drucker. Zum Lesen benötigen Sie den Acrobat Reader ab Version 5. Zusammen mit Ihrem Patentportfolio erhalten Sie eine Lizenznummer, die Ihnen den Zugriff auf die Datei ermöglicht. Die Zusammenstellungen geben einen komfortablen Zugriff auf alle Patenttitel. Diese können ohne ein Wechseln der Datei alle betrachtet und auch ausgedruckt werden.

Angaben zum Nominalwert einer Patentzusammenstellung beziehen sich auf einen Durchschnittspreis von 3,50 Euro pro Patentschrift in PDF Form, der von führenden Anbietern und Agenturen berechnet wird.
