技術說明

本發明之高拉滑輪健身裝置包含底座、磁流變液阻力器、控制器、齒輪組、滑輪、鋼索組及拉引桿，磁流變液阻力器係提供阻力以作為下拉該拉引桿之負載配重，並可藉由控制器控制輸入磁流變液阻力器之電流，來改變磁流變液阻力器輸出阻力大小，本發明之高拉滑輪健身裝置可精準、方便且快速地在健身訓練過程中改變阻力之優點；相較於習知技術中採用槓片之配重方式，本發明之高拉滑輪健身裝置不被以一個槓片為單位的重量調整所限制，在訓練強度的調整上可有更多選擇及控制解析度，再者，本發明之高拉滑輪健身裝置中的磁流變液阻力器之體積相較於堆疊的槓片更小且更輕，而大幅降低了整個裝置的體積與重量。 A lat pulldown fitness device includes an MRF resistance provider to provide a resistance functioning as a load weight of pulling down the pulldown bar. The controller controls a current input to the MRF resistance provider to change the strength of the resistance output from the MRF resistance provider. During a workout, the resistance provided by the lat pulldown fitness device is changeable precisely, conveniently, and quickly. Unlike its conventional counterparts which require bumper plates for use as weights, the lat pulldown fitness device is not limited to weight adjustment based on unit bumper plate but features plenty choices and controllable resolution in terms of strength of training. Furthermore, the MRF resistance provider of the lat pulldown fitness device is more compact and lightweight than any stacked bumper plates and thus reduces the total volume and weight of the lat pulldown fitness device greatly.
