US 2015/0143949 A1 · SEMI-FIXED TYPE SHOE-FIXING SHAFT

Abstract

Provided is a semi-fixed type shoe-fixing shaft that includes a shaft rotatably mounted on a crank, a ratchet pawl swingably installed on the shaft, a ratchet engaging tooth fixed to the crank so as to catch the ratchet pawl, a ratchet spring fixed to the shaft so as to swing the ratchet pawl, a ratchet control lever connected to the ratchet spring and slidably installed on the shaft, and a shoe fixing hook fixed to the shaft. The shoe fixing hook and a fastener fixed to a cycling shoe are coupled. Thereby, the cycling shoe and the shaft are fixed, and a force for stretching an ankle is transmitted through the cycling shoe and the shaft as a force for rotating the crank. Muscles around a calf for moving the ankle can be used as a rotational force for the crank.
