Description

Side-open folding pedal

The present invention relates to the technical field of bicycle pedal structures, and more particularly to a side open folding pedal.

Since the pedal of the bicycle is generally coupled to the crank in a direction perpendicular to the body of the vehicle, the bicycle body will increase a lot of structural volume on both sides, and the packaging cost, storage cost and transportation logistics cost of the vehicle body structure will often follow. Relatively improved; therefore, the manufacturer has introduced the design concept of the folding pedal to reduce the volume of the bicycle body through the folding of the pedal structure.

For example, the "Folding Pedal" patent of the Republic of China Announcement No. M253547, which is described in the first paragraph of the patent application: "a folding foot pedal comprising a movable step frame unit and a positioning step unit a second elastic unit disposed between the two, and a mandrel rotatably disposed on the positioning step unit; the movable step frame unit includes a frame body and is fixed to the frame body and spaced apart from each other The two struts and the second stop; the positioning pedestal unit comprises a positioning seat and a second blocking member, the positioning seat has a shaft tube, and the first wing block, the second wing block and the respectively separated from the shaft tube a second spacer between the two wing blocks, the shaft tube and the wing blocks cooperate to define two first chambers for accommodating the two pillars, and two second chambers for accommodating the two pillars; The two elastic units are separately fired The abutment is located between the two pillars and the two spacers and is respectively located in the two first compartments; thereby, the invention has the characteristics of better overall rigidity and convenient folding. "."

However, because the M253547 patent has a guide groove 333, 343 disposed on the opposite inner faces of the first end portions 331, 341 of the first wing block 33, the second wing block 34, and along the shaft tube 32, The guiding block 242 is inserted into the strut cylinder of the movable striking frame unit strut 24 on the positioning step unit and located at the opposite end of the opposite pedal crank; and respectively engaging an elastic unit 40 to elastically support the movable step frame unit. The movable step frame unit is rotated by the pillar cylinder moving in the guide groove to form a fold opposite to the positioning seat. As shown in FIG. 12 of the patent No. M253547, since the guide grooves 333 and 343 of the movable step frame unit are perpendicular to the pedal crank, the positioning step unit must vertically protrude a distance larger than the guide groove; After the pivoting of the step frame unit at the outer end of the guide groove, there is still a protruding distance relative to the pedal crank of the patent FIG. 12, and the overall volume cannot be effectively received, resulting in packaging cost, storage cost and transportation logistics. The inability to effectively reduce the cost is a disadvantage of the conventional pedal structure.
