Patent number: 5437347Abstract: The invention deals with a cable tensioning system for elevators with separate drive cable and support cable lines 10, 11, which both engage at an elevator cabin 12 and also at a counterweight 13, characterized in that the cable tensioning system comprises a rocker 20 configured as a lever and supported at the counterweight 13 or the elevator cad 12, at which rocker the support cable 11 and the drive cable 10 are fastened to be spaced from each other, that the spacing ratio a: b of the attachment points 31, 32 of the cable lines 10, 12 at the rocker 20 from the support point 21 of the rocker 20 at the counterweight 13 or the elevator cab 12 define the cable tension or pull ratio required for the driving capacity.Type: GrantFiled: May 12, 1994Date of Patent: August 1, 1995Assignee: C. Haushahn GmbH & Co.Inventors: Joachim Biewald, Volker Scheub, Helge Holler, Karl Fenkl, Stefan Hugel, Wolfgang Barth, Hans-Georg Grell, Martin Grosser, Hermann Moll, Horst Pollmann, Peter Schneider

Patent number: 5377788Abstract: A safety catch device for elevator cars guided on at least one guide rail includes a braking device acting on the at least one guide rail for braking the elevator car and a control device for controlling the braking force of the braking device in dependence on the load and/or deceleration. The control device includes a control mass which is influenced by the acceleration of the elevator car and a brake spring which is deflected in accordance with the position of the control mass. The brake spring is coupled to the control mass and the braking device in such a way that a reduced braking force is applied by the braking device on the at least one guide rail in the case of a high deceleration of the elevator car and an increased braking force is applied by the braking device on the at least one guide rail in the case of a lower deceleration of the elevator car.Type: GrantFiled: July 30, 1993Date of Patent: January 3, 1995Assignee: C. Haushahn GmbH & Co.Inventors: Joachim Biewald, Volker Scheub, Helge Holler, Karl Fenkl, Stefan Hugel, Jorg Rothaupt, Peter Schneider, Wolfgang Barth, Hermann Moll, Horst Pollmann

Patent number: 5375417Abstract: A pneumatic motor having a plurality of cylinders, with each cylinder having an expansion chamber (15), defined in part by a piston plate (2); and a diversion chamber (16) which is divided into two chambers by a slide plate (11), with the diversion chambers connected to a pressure supply line (27) and to a pressure diversion line (28). The piston plate is connected to a piston rod (5) by a lock (3). The expansion chamber holds an amount of compressed air held constant throughout the operation cycle. Expansion of the expansion chamber moves the piston plate and piston rod (5) to rotate a crankshaft (5a). At the end of the expansion stroke, the piston rod is disconnected from the piston plate. The expansion chamber is compressed by pressurizing the diversion chamber below the slide plate (11), forcing the slide plate and push rods (7) upwards, which pushes the piston plate upwards, until the piston plate can be held at a top position by a lock (3').Type: GrantFiled: December 9, 1993Date of Patent: December 27, 1994Inventor: Wolfgang Barth
