Abstract
1. Pedal crank driving means for bicycles or the like, comprising a rotatable seated crank shaft, at each of the end of which a pedal is seated rotatable about an axis parallel to said crank shaft by means of crank arms being displaced against one another about 180 and being telescopically controlled to be lengthened or shortened, each of which crank arms having a case fixed at the crank shaft and a rod extractable from the case, whereby the case of each crank arm comprises an oblong hole passed by a bolt seated at said rod being guided resistant to torsion in said case, which bolt carries a cam follower roller passing over the way of a fixed cam disk, and whereby opposite of the cam way a guiding way is provided at a distance which corresponds to the diameter of said cam follower roller, characterized in that the guiding way strap (20) extends only over that portion of the periphery of said cam disk (17) effecting the shortening of said crank arm and that the extracting length of said rod (8) is limited by an end of said oblong hole (12) when said cam follower roller (15) runs along the guiding way free portion of said cam disk (17).
