Abstract
Abstract A toe clip is attached to a bicycle pedal and holds a driver's foot thereon in cooperation with a toe strap. The toe clip body is formed of a plate curved forward at a substantially intermediate portion thereof and has the curved portion and a first and second free end portions extending rearwardly thereof. At both side edges of the clip body between the lower end of curved portion and the rear edge of second free end portion are provided a pair of rising pieces approximately equal in height to a front plate at the pedal so that when attached to the pedal for use, the toe clip has a reduced resistance against air flow.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
282 words
A toe clip for attachment to a bicycle pedal having a front and a rear plate for holding, in cooperation with a toe strap, a driver's foot onto said pedal, said toe clip comprising: a clip body formed of an elongate plate curved forward at its substantially intermediate portion to form a curved portion having upper and lower ends and a first and second free end portion respectively extending rearwardly from the upper and lower ends of said curved portion, said second free end portion sloping downwardly to the rearmost end of said clip body, said rearmost end of said second free end portion at its lowest level terminating at the lowest level of said pedal front plate, said clip body being provided at both side edges thereof between the lower end of said curved portion and the rearmost edge of said second free end portion with a pair of rising sidewall pieces which are triangular in shape, each of said rising sidewall pieces having an upper surface which terminates substantially at the level of upper surfaces of said front and rear plates of said pedal and being in horizontal continuation of the level of said upper surfaces so that, when said clip body is mounted on said pedal, said second free end covers the front surface of said front plate of said pedal so as to introduce air flow rearwardly without striking against the front surface of said front plate, thereby reducing resistance against air flow; and, a holder provided at said first free end portion of said clip body for holding said toe strap; said toe clip, when attached to a bicycle pedal, providing a reduced resistance against air flow.
Claim 2
Dependent Claim
282 words
A toe clip for attachment to a bicycle pedal having a front and a rear plate for holding, in cooperation with a toe strap, a driver's foot onto said pedal, said toe clip comprising: a clip body formed of an elongate plate curved forward at its substantially intermediate portion to form a curved portion having upper and lower ends and a first and second free end portion respectively extending rearwardly from the upper and lower ends of said curved portion, said second free end portion sloping downwardly to the rearmost end of said clip body, said rearmost end of said second free end portion at its lowest level terminating at the lowest level of said pedal front plate, said clip body being provided at both side edges thereof between the lower end of said curved portion and the rearmost edge of said second free end portion with a pair of rising sidewall pieces which are triangular in shape, each of said rising sidewall pieces having an upper surface which terminates substantially at the level of upper surfaces of said front and rear plates of said pedal and being in horizontal continuation of the level of said upper surfaces so that, when said clip body is mounted on said pedal, said second free end covers the front surface of said front plate of said pedal so as to introduce air flow rearwardly without striking against the front surface of said front plate, thereby reducing resistance against air flow; and, a holder provided at said first free end portion of said clip body for holding said toe strap; said toe clip, when attached to a bicycle pedal, providing a reduced resistance against air flow.
Claim 3
Dependent Claim
56 words
A toe clip according to claim 1, wherein said clip body is gradually reduced in width from said second free end portion toward said first free end portion, and said curved portion is provided with a substantially triangular window, said window being provided at its side edges with a plurality of air-flow rectifying plates extending upwardly.
Claim 4
Dependent Claim
66 words
A toe clip according to claim 1, wherein said clip body is provided at the rearmost edge of said second free end portion with a mounting piece which rises upwardly throughout the width of said second free end portion and which is attachable to said pedal, said mounting piece and said pair of rising sidewall pieces, forming a box-like shape for said second free end portion.
