Stationary ergometric exercise device

摘要

A stationary ergometric exercise device (10) comprises afoot-operable drive including alternately operable drive elements in the form of foot-driven pedals (18) mounted via pedal cranks (20) to opposite sides of a drive wheel (22). A flywheel (24) is coupled to the drive wheel (22) via a gear mechanism (26), the flywheel including a magnetic rim (38). The exercise device (10) includes a brake device (40) in the form of one or more ~ o permanent magnets (44a,44b) mounted for movement by means of a motor (42) towards and away from the magnetic rim (38) of the flywheel (24) so as to selectively adjust a braking force applied to the flywheel (24) by means of the or each permanent magnet (44a,44b). 15 A measuring unit (58) is provided for measuring, in use, at least, one of drive force applied via the drive and the torque related to it, together with a measuring device (66) for measuring, in use, cadence. A command module (72) is connected to the measuring unit (58), the measuring device 20 (66) and the motor (42) of the brake device (40), and a communications module (74) is connected to the command module (72) and configured to receive command signals and transmit those command signals to the command module (72) and configured to transmit feedback signals received from the command module (72) reporting user performance. 25 The command module (72) is configured to receive measurements from the measuring unit (58) and the measuring device (66) and to use those measurements to calculate one or more performance parameters and to compare the or each performance parameter against a predetermined performance profile. The command module (72) is also configured to control the motor (42) so as to move the or each permanent magnet so (44a,44b) relative to the magnetic rim (38) of the flywheel (24) in order to adjust the braking force applied by the or each permanent magnet (44a,44b) and thereby tune the measurements received from the measuring unit (58) and the measuring device (66) so as to adjust the or each performance parameter calculated by the command module (72) to conform with the predetermined performance profile.
