MULTI-FUNCTION EXERCISE MACHINE

摘要

A machine for exercising a person's muscles contains a frame (100, 10OY, or 100Z). a seat (102), a seatback (104, 104U, or 104Y), aconnection mechanism (106, 106U, or 106Y) for flexibly and adjustably connecting the seatback to the frame or/and the seat, and a pedaling mechanism (112, 112Y, 112Z, or 220) having movable foot pedals (140 or 224) that revolve or translate back and forth. The seatback is typically capable of swiveling and can be segmented to facilitate swiveling. Retractable legs (302) may be provided for enabling the machine to be used for stationary cycling when the legs are retracted and as an elevated exercise bench when the legs extend downward. The machine may include mechanisms for rapidly switching the legs between their retracted and extended positions and for rapidly switching the seatback between inclined and flat positions. Alternatively, the machine may have permanently extended legs (470). Another exercise machine contains a handle- translating mechanism (220) having a pair of handles (274) that translate back and forth.
