Patent number: 4921243Abstract: A motion device which provides circulatory stimulation and therapy of vascular disorders of legs. The motion device comprises two pivoting pedals positioned in a heel area on a base plate. The pedals are connected to a mechanism positioned between the pedals. The mechanism comprises a crank system having a shaft which is parallel to the pivoting axis of the pedals so that the pedals must be moved in push-pull motion. The shaft is connected with a transmission gearing which drives a flywheel. Thus the user of the device can easily overcome the top dead center points during operation. Through the use of a brake operating lightly on the flywheel, the necessary magnitude of force when stepping on the pedals can be sensitively adjusted.Type: GrantFiled: October 7, 1988Date of Patent: May 1, 1990Inventor: Ulrich Weidmann

Patent number: 4353526Abstract: The invention relates to electrical drive apparatus for a vertically displaceable blackboard. In order to obtain synchronous operation of such drive apparatus either one motor, one shaft, or two motors connected by means of an electrical shaft were employed. The apparatus according to the invention operates with an electric motor which is combined with a worm drive, a drive sheave, and a slip coupling to a unit which is mounted at the top inside the guide beams of the blackboard, with the motor arranged vertically and having a hollow shaft through which the drive cable is guided. One such drive apparatus is mounted in each guide beam at its top, with simultaneous switching on and switching off without an electrical shaft.Type: GrantFiled: April 10, 1980Date of Patent: October 12, 1982Inventor: Ulrich Weidmann

Patent number: 4304442Abstract: The invention relates to a guide system for a counterweight that is mounted in a box-shaped profile beam, in particular for blackboards. The hollow profile beam has to this purpose on its inside longitudinal guides (17 and 18). Above and below on the counterweight (20) there are provided elastomeric bands (30) with integrally vulcanized hard-rubber elements (31) that are in light sliding contact with the longitudinal guides and that guide the counterweight during its upward and downward displacement.Type: GrantFiled: April 10, 1980Date of Patent: December 8, 1981Inventor: Ulrich Weidmann
