Granted: 1985-09-19
Abstract: Die Erfindung betrifft einen Treppen-Schrägaufzug, bestehend aus einer Plattform (3Δ), die an einer längs einer Treppe verlaufenden Transporteinrichtung verfahrbar ist. Bergseitig und talseitig sind an einer mit der Plattform verbundenen Seitenwand (2Δ) od.dgl. gelagerte, aus einer vertikalen, nach oben geschwenkten Auffahrstellung in eine horizontal gerichtete Sperrstellung schwenkbare Barrieren (1, 1Δ) vorgesehen. Die Barrieren (1, 1Δ) sind während der Fahrt gegen Schwenkung nach oben und unten verriegelt. Nur an den Haltestellen ist die Schwenkung einer Barriere nach oben möglich. Bei Nichtgebrauch wird die Plattform (3Δ) gegen die Seitenwand (2Δ) hochgeklappt und die Barrieren (1, 1Δ) werden nach unten geschwenkt, so daß sie über die Plattform (3Δ) zu liegen kommen. Damit die Schwenkung der Barrieren (1, 1Δ) nach unten nur bei hochgeklappter Plattform (3Δ), nicht aber während der Fahrt, möglich ist, sieht die Erfindung einen schwenkbaren Hebel (5) vor, der durch eine Feder (9), solange die Plattform (3Δ) nicht hochgeklappt ist, ständig in den Schwenkbereich der Barriere (1, 1Δ) gedrückt wird und dort mit einem seitlich vorragenden Ansatz (7) einen Stoppanschlag gegen Schwenkung der Barriere (1, 1Δ) nach unten bildet. Beim Hochklappen der Plattform (3Δ) stößt ein an der Plattform vorgesehener Ansatz (3) gegen den Hebel (5) und drückt diesen gegen die Kraft der Feder (9) aus dem Schwenkbereich heraus, so daß die Barriere (1, 1Δ) nach unten geschwenkt werden kann (Fig. 5). .

Abstract: A surgical stapler powered by a relatively low pressure gas supply contained in the stapler. The stapler has a mechanical linkage between the pneumatic actuator and the staple driver with a differential mechanical advantage to match the substantially constant force provided by the pneumatic actuator to the different forces required to first advance and then form the staple. This mechanical linkage allows use of a relatively small low pressure actuator and also substantially increases the efficiency with which the gas supply is utilized.
