Abstract

The torque wrench has two threaded discs (1a,1b) joined by connecting screws (2) to form a block screw (3) on which a scale (4) is inscribed which indicates the torque level set. The discs enclose an elastic seal (5) which forms a seal around the tool and also against the body (6) of the wrench. When turned, the threaded discs act upon a curved spring (7) which puts a specific pressure upon a transport wheel (8). Turning the handle of the wrench moves the transport wheel and a sliding spring (11) in the same direction. Coupling balls (12) join the transport wheel to the coupling piece (13) which has an engaging pin (14) joined to the tool. When the pre-set torque is exceeded, the coupling balls are forced out of their seats and the turning force is no longer transmitted to the tool.

Description

Die Neuerung betrifft eine Verbesserung von Einschraub- Vorrichtungen für Dental-, Implantat- und Prothetik- Verschraubungen.The innovation concerns an improvement of screw-in Devices for dental, implant and prosthetic Fittings.

Um Implantat- und Prothetik-Systeme in der Dental- Medizin mit größtmöglicher Zuverlässigkeit einsetzen zu können, schreiben Hersteller für ihre Systeme optimale Drehmomente vor.To implant and prosthetic systems in dental Use medicine with the greatest possible reliability To be able to, manufacturers write optimal for their systems Torques.

Es sind Momenten-Schraubendreher bekannt, die diese Aufgabe zwar erfüllen, aber dennoch bei gewissen Montage- Behandlungen eine Ratsche wünschenswert oder gar erforderlich machen.There are known torque screwdrivers that do this Do the job, but still with certain assembly Treatments a ratchet desirable or even necessary do.

Die hiermit vorgestellte Drehmomenten-Ratsche mit Doppel- Funktion erfüllt diesen Zweck.The torque ratchet with double Function fulfills this purpose.

Die Neuerung besteht nun darin, daß die Ratsche auf verschiedene erforderliche Drehmomente einstellbar ist.The innovation now is that the ratchet on different required torque is adjustable.

Auf diese Weise erfüllt die Drehmomenten-Ratsche zwei Funktionen, sowohl als Ratsche wie auch als Überlastsicherung.In this way, the torque ratchet fulfills two functions, both as a ratchet and as overload protection.
