Patent ID: 8225635

Claim:
A method for making a bicycle pedal, characterized by comprising the following steps: (A) cutting, in which a rolled metal tube or an aluminum extruded tube is selected and cut to form a hollow pedal frame; (B) drilling, in which the pedal frame is machined to form penetrating coupling holes; (C) welding, in which a collar is mounted outside the pedal frame concentric with respect to each of the coupling holes through welding to provide a sufficient contact area in which a spindle is rotatably received and supported, whereby the pedal frame is rotatable about the spindle for pedaling operation of a bicycle; and (D) performing assembling operation after step (C), wherein a plastic sleeve is set within a bore of each of the collars and an outer tube is set to bridge and connect between the two coupling holes with opposite ends of the outer tube constrained by the two sleeves, the outer tube and the sleeves forming respectively centrally penetrating bores so that the bores of the sleeves receive therein bearings and sealing ring with a spindle rotatably received in and extending through the bearings, wherein an end of the spindle is adapted to mount to a crank and an opposite end forms an externally-threaded section for being tightened by a nut, and the sleeve associated with the opposite end of the spindle is closed by a cap, whereby the nut provides a tightening force that securely fixes the sleeves, the outer tube, the bearings, and the spindle together to allow the pedal frame to be rotatable about the spindle.
