Abstract

A self-illuminating pedal assembly comprises a pedal axle, a pedal rotatably mounted around the pedal axle, a magnet securely mounted to the pedal axle, and a permanent-magnet coil securely mounted to the pedal to rotate therewith. At least one light-emitting diode is mounted to the pedal. The permanent-magnet coil is electrically connected to the light-emitting diode and surrounds the magnet. When pedaling, the permanent-magnet coil is rotated relative to the magnet to thereby generate an alternating magnetic field to cause illumination of the light-emitting diode.

  • FIG. 6 is a schematic view of a bicycle equipped with the self-illuminating pedal assemblies in accordance with the present invention.[0021]
    • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
  • Referring to FIGS. 1 and 2, a self-illuminating pedal assembly in accordance with the present invention generally includes a [0022] pedal 10, a generator 30, and a pedal axle 50. The pedal 10 includes a longitudinal through-hole 11 through which the pedal axle 50 extends, thereby rotatably mounting the pedal 10 around the pedal axle 50. The longitudinal through-hole 11 of the pedal 10 includes two ends each having an enlarged receiving portion 111 for receiving a bearing 20. Each bearing 20 includes a hole 21 through which the pedal axle 50 extends. A washer 54 and a nut 55 are attached to a threaded end 52 of the pedal axle 50 to prevent disengagement of the pedal assembly. The pedal 10 further includes a plurality of holes 14 in two opposite sides thereof, each hole 14 having a light-emitting diode 33 mounted therein.
  • The [0023] pedal 10 further includes a compartment 12 outside the longitudinal through-hole 11 yet communicated with the longitudinal through-hole 11. The generator 30 is received in the compartment 12 and includes a permanent-magnet coil 31 and a ring magnet 32 surrounded by the permanent-magnet coil 31. The permanent-magnet coil 31 includes a central hole 311 for receiving the ring magnet 32, which, in turn, includes a central hole 321 through which the pedal axle 50 extends. The permanent-magnet coil 31 is electrically connected to the light-emitting diodes 33 in the pedal 10. The permanent-magnet coil 31 includes a plurality of protrusions 312 on an outer periphery thereof for securely engaging with positioning grooves 121 in an inner periphery defining the compartment 12. Thus, the permanent-magnet coil 31 is securely attached to the pedal 10 to rotate therewith.
  • The [0024] other end 51 of the pedal axle 50 is also threaded for connection with a crank 61 (FIG. 6) of a bicycle 60. A flange 53 is formed on the pedal shaft 50. A cover 40 includes a central hole 42 so as to be mounted around the pedal axle 50. The cover 40 is retained in place by bearing against the flange 53 and includes two ears 41. A screw 43 is extended through a hole 411 in each ear 41 and a hole 131 of an associated lug 13 on the pedal 10. Thus, the cover 40 is attached to a side of the pedal 10 for housing the generator 30, best shown in FIG. 3.
  • The [0025] ring magnet 32 in FIG. 4 is still relative to the permanent-magnet coil 31. Referring to FIG. 5, when the ring magnet 32 is rotated relative to the permanent-magnet coil 31, an alternating magnetic field is generated, which, in turn, generates electric current. The light-emitting diodes 33 electrically connected to the permanent-magnet coil 31 illuminate accordingly. Referring to FIG. 6, in actual cycling, the pedal is turned relative to the pedal axle 50 during pedaling, the permanent-magnet coil 31 is thus rotated relative to the ring magnet 32. The light-emitting diodes 33 electrically connected to the permanent-magnet coil 31 illuminate accordingly.
  • According to the above description, it is appreciated that the light-emitting [0026] diodes 33 illuminate while pedaling, thereby providing an alarming effect. No batteries are required. In addition, the overall structure and assembly of the self-illuminating pedal assembly in accordance with the present invention are simple, and the cost therefor is low.
  • Although the invention has been explained in relation to its preferred embodiment, it is to be understood that many other possible modifications and variations can be made without departing from the scope of the invention as hereinafter claimed. [0027]
