Embodiment

[0023] Foldable pedals include a pair of pedal boards 1, a pair of pedal shafts 2, a pair of cranks 3, two connecting pins 4, crank shaft a6, crank shaft b8, two fastening nuts 5 and a clutch, wherein, Clutch is made up of sleeve 71, pin a72 and pin b73, and two long slide slots 74 are arranged symmetrically up and down on the diameter of the circular surface at one end of the sleeve 71, and are symmetrically opened up and down on the diameter of the circular surface at the other end of sleeve 71. There are two short chutes 75, and the length ratio of the long chute 74 and the short chute 75 is long: short=2:1.

[0024] The pedal plate 1 is fixedly connected to one end of the crank 3 provided with the threaded round hole through the screw thread of the pedal shaft 2, and the other end of each crank 3 provided with a concave fork is respectively provided with a screw thread with the crank shaft a6 through the connecting pin 4. The flat part of one end of the crankshaft b8 is co...

Abstract

The invention discloses a folding type pedal, relates to a structure of cranks operated by feet, and is a double-crank rotary folding type pedal adopting the clutch principle. The folding type pedal comprises a pair of pedal plates, a pair of pedal shafts, a pair of cranks, two connecting pins, a crank shaft a, a crank shaft b, two clamp nuts and a clutch, wherein the clutch consists of a sleeve,a pin a and a pin b, two long sliding chutes are symmetrically arranged in the upper surface and the lower surface of the circular-surface diameter of one end of the sleeve, and two short sliding chutes are symmetrically arranged in the upper surface and the lower surface of the circular-surface diameter of the other end of the sleeve. According to the folding type pedal, the pedal plates are avoided being folded, the service life of the pedal is prolonged, the reliability of the pedal is improved, the folding operation is simple and convenient, and the folding type pedal is not only suitablefor folding bicycles, but also used for various folding tools driven by manpower, such as folding body-building chairs and folding wheel chairs.

Description

technical field [0001] The technical solution of the present invention relates to a crank structure operated by feet, specifically a folding pedal. Background technique [0002] With the growing tension of petroleum energy and environmental pressure, human-driven vehicles are popular among urban residents again due to their convenience and flexibility. In view of the fact that collapsible human-driven vehicles such as folding bicycles have the advantage of being easy to carry, people's needs will become more and more urgent. CN2825448 discloses a folding bicycle pedal, which is flipped and folded by the pedal board. Since the pedal board is a force-bearing object directly exerted by the human foot, repeated folding of the pedal board will reduce its service life; CN101633386 discloses a bicycle combination Type folding pedals, the folding process is divided into two steps: first fold the pedal plate, and then fold the crank. In this way, not only the folding of the pedal b...
