POSITION SENSOR, SENSOR ARRANGEMENT AND REHABILITATION DEVICE

摘要

Position sensor comprises having a holder, a force measuring device permanently connected to the holder, and a winding device, which is permanently connected to the force measuring device and has a drive having an electric motor. Winding device is configured to unwind and wind a cable and to determine an unwinding length of the cable. Guide device permanently connected to the holder has a centering device for passing through the cable, an outlet apparatus which is mounted on universal joints and is intended to pass through the cable with a variable direction, and a position sensor for determining an angular position of the outlet apparatus. Position sensor is set up to determine position of a predetermined point of the cable relative to holder on the basis of determined angular position and unwinding length.

主权项

1. Position sensor comprised of
a holder (3);
a firmly with the holder (3) connected force measuring device (5); a firmly with the force measuring device (5) connected winding device (6, 16) with a drive (7), featuring an electric motor (7), the winding device (6, 16) set up to unwind and wind the cable (8) and for the determination of an unwinding length of the unwound cable (8); and a with the holder (3) firmly connected guiding device (11) featuring a centering device (13) for a defined, fixed-direction passing through of the cable (8), a gimbal-mounted outlet apparatus (15) for a variable-direction passing through of the cable (8) and a position sensor to determine an angular position of the outlet apparatus (15); whereas the position sensor (1, 2) is designed to determine the position of a predefined point of the cable (8) relative to the holder (3) based on the determined angular position and the unwinding length; and whereas the electric motor (7) is set up to act on the cable (8) with an adjustable tensile force, which is adjusted based on a force which acts on the holder (3) via the cable and which is determined by the force measuring device (5).
