Abstract
Abstract A pedal for racing bicycle comprises a pedal body carrying a toe clip at the front with a strap for retaining a cycling shoe and a transverse stop at the rear which is adapted to engage a recess formed in a cleat fitted to the sole of the shoe. The transverse stop is movable relative to the body of the pedal so as to enable the cleat to be released in use as a result of a backward and/or rotary force applied by the shoe above a threshold value.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
201 words
A pedal for racing bicycles, comprising a pedal body carrying a toe clip with a strap for retaining a cycling shoe at the front, a transverse stop in the form of a projecting plate movably mounted at the rear of said pedal for engagement in a recess formed in a cleat fitted to the sole of the cycling shoe, and adjustable resilient means engaging said transverse stop whereby said transverse top is movable relative to said pedal so as to enable its release from the cleat in use as a result of a force applied by the shoe above a threshold value to overcome said resilient means wherein an intermediate element is articulated to said pedal body about a main axis substantially parallel to said transverse stop, said transverse stop being connected to said pedal body with the interposition of said intermediate element and being rotatable relative thereto about an auxiliary axis substantially perpendicular to said main axis so as, in use, to allow said transverse stop to be release from the cleat as a result of a pivoting force applied by the shoe of a predetermined magnitude about a substantially vertical axis and subsequent backwards movement of the shoe itself.
Claim 2
Dependent Claim
201 words
A pedal for racing bicycles, comprising a pedal body carrying a toe clip with a strap for retaining a cycling shoe at the front, a transverse stop in the form of a projecting plate movably mounted at the rear of said pedal for engagement in a recess formed in a cleat fitted to the sole of the cycling shoe, and adjustable resilient means engaging said transverse stop whereby said transverse top is movable relative to said pedal so as to enable its release from the cleat in use as a result of a force applied by the shoe above a threshold value to overcome said resilient means wherein an intermediate element is articulated to said pedal body about a main axis substantially parallel to said transverse stop, said transverse stop being connected to said pedal body with the interposition of said intermediate element and being rotatable relative thereto about an auxiliary axis substantially perpendicular to said main axis so as, in use, to allow said transverse stop to be release from the cleat as a result of a pivoting force applied by the shoe of a predetermined magnitude about a substantially vertical axis and subsequent backwards movement of the shoe itself.
Claim 3
Dependent Claim
57 words
A pedal according to claim 1, wherein guide means are provided between said transverse stop and said pedal body for allowing said transverse stop to pivot relative to said main axis as a result of a rotation of said transverse stop about said auxiliary axis caused by the pivoting of the shoe about a substantially vertical axis.
Claim 4
Dependent Claim
35 words
A pedal according to claim 2, wherein resilient means are interposed between said transverse stop and said intermediate element and arranged to urge said transverse top into its operative position and to oppose its pivoting.
Claim 5
Dependent Claim
28 words
A pedal according to claim 2, wherein said guide means comprise an L-shaped aperture formed in said transverse stop and a corresponding pin fixed to said pedal body.
Claim 6
Dependent Claim
27 words
A pedal according to claim 2, wherein said guide means comprise an L-shaped aperture in said pedal body and a corresponding pin fixed to said transverse stop.
Claim 7
Dependent Claim
32 words
A pedal according to claim 2, wherein said pedal body defines a shaped seat for cooperating with an auxiliary pin to prevent premature rotation of said transverse stop about said main axis.
Claim 8
Dependent Claim
29 words
A pedal according to claim 3, wherein said resilient means comprise a helical spring arranged to be compressed during the rotation of said transverse stop about said auxiliary axis.
Claim 9
Dependent Claim
30 words
A pedal according to claim 7, wherein said resilient means further include an auxiliary spring for urging said transverse stop to pivot about said main axis towards its operative position.
Claim 10
Dependent Claim
36 words
A pedal according to claim 7, wherein said helical spring defines an axis substantially parallel to said main axis and is compressed between corresponding abutment flanges projecting from said transverse stop and from said intermediate element.
Claim 11
Dependent Claim
82 words
A pedal according to claim wherein said abutment flanges support, coaxially with said helical spring, a pin having a threaded end for cooperating with a corresponding threaded hole defined in one of said abutment flanges and an annular portion against which bears one end of said spring, the rotation of said pin causing a variation in the preloading of said spring for adjusting the pivoting force of the shoe which is able to cause release of the cleat from the transverse stop.
