| 摘要 |
A carriage-type leg press exercise machine which applies a pre-determined variably resistive force to an operator's thigh and hip extending muscles through the use of a kinematically derived double-rocking-lever four-bar linkage, whose rocking follower lever constitutes a rotating weight arm to which weights are loaded and whose rocking driver lever is mechanically linked to an operator-engaging guided-carriage assembly which slides along the path of the leg press exercise movement, as is conventional.
