Problems solved by technology

However, when the tensioning mechanism of these prior art clipless or step-in bicycle pedals is tightened or unscrewed, the component may become completely disengaged from other parts of the tensioning mechanism and / or the bicycle pedal itself
It is very difficult to reattach the small parts of the tension adjustment mechanism of these bicycle pedals
Also if the parts of the tension adjustment mechanism are disengaged from the bicycle pedals some small parts may be lost

Embodiment Construction

[0051] first reference Figure 1-4 , illustrates a bicycle pedal 10 according to a preferred embodiment of the present invention. The bicycle pedal 10 is a clipless step-in or pedal that can be used with a bicycle shoe 12 with a clip 14 attached thereto. Bike pedals 10 are specially designed for off-road bikes, unlike road bikes. Of course bicycle pedals 10 could also be used with road bicycles or any type of bicycle if needed and / or desired. Such as figure 1 As shown in FIG. 2 , bicycle pedal 10 is fixedly connected to a crank arm 16 of the bicycle for rotation therewith, while clamp 14 is fixedly connected to the bottom of bottom surface 18 of shoe 12 .

[0052] exist Figure 1-4 The bicycle pedal 10 illustrated in is a left pedal. Of course the same pedals are provided on the right and left side of the bicycle, but the right pedal is a mirror image of the left pedal 10 . The right pedal will therefore not be discussed or illustrated in detail here.

Abstract

A bicycle pedal includes a pedal shaft, a pedal body, first and second clamping members and a first biasing member. The pedal body is rotatably mounted on the pedal shaft. The first clamping member has a first cleat engagement surface and is pivotally mounted, while the second clamping member has a second cleat engagement surface and is fixedly coupled to the pedal body. The second clamping member is configured to form an unobstructed passageway. Preferably, the second clamping member includes two outer attachment point and an inner attachment point. An adjustment member is arranged between the first clamping member and a biasing member to adjust tension of the biasing member on the first clamping member. The adjustment member has a head arranged in a hole of the first clamping member, an enlarged section and an adjustment plate adjustably mounted on the adjustment member.

Description

technical field [0001] This invention generally relates to pedals for bicycles. More particularly, the present invention relates to clipless or step-on bicycle pedals having a front clip member with an enlarged unobstructed passage for the free passage of mud. Background technique [0002] Cycling has increasingly become a form of public entertainment and a means of transportation. Also, cycling has become a popular competitive sport. Whether bicycles are used for recreation, transportation or competition, the bicycle industry is constantly improving their components. Bicycle pedals are a particular component of bicycles that have been extensively redesigned over the past few years. [0003] Various bicycle pedals have been designed in recent years for special purposes such as recreation, off-road cycling, on-road racing, and the like. A particular type of bicycle pedal, which is becoming more and more common, is the clipless or step-on pedal, which releasably engages a ...
