Willie's Crancks

Abstract

A modified crank arm with an elevated point of leverage and angle of support in relation to the crank arm is disclosed. When the point of leverage in the bicycle pedaling motion is increased, crankset rotation can be done with less physical effort of the cyclist and more bicycle speed is produced by the perpetual motion.

Claims

1. A modified bicycle crank arm comprising: an elongated body having a first end member and a second end member; an axle hole opening extending through the elongated body at center of the first end member; and a threaded pedal hole opening extending through the elongated body at the center of the second end member whereby the second end member is bent.

2. The modified bicycle crank arm of claim 1 wherein the centerline axis of the threaded pedal hole opening is at least 10 degrees off center of the centerline axis of the axel hole opening.

3. The modified bicycle crank arm of claim 1 where in the second end member is bent upwards at least 10 degrees off center of the centerline axis of the axel hole opening or bent downwards at least 10 degrees off center of the centerline axis of the axel hole opening.

DETAILED DESCRIPTION OF THE INVENTION

[0023] The present invention overcomes the limitations of the prior art by providing a new and more effective crank arm.

[0024] All dimensions specified in this disclosure are by way of example only and are not intended to be limiting. Further, the proportions shown in these Figures are not necessarily to scale. As will be understood by those with skill in the art with reference to this disclosure, the actual dimensions and proportions of any embodiment or element of an embodiment disclosed in this disclosure will be determined by its intended use.

[0025] It is to be understood that the drawings and the associated descriptions are provided to illustrate potential embodiments of the invention and not to limit the scope of the invention. Reference in the specification to one embodiment or an embodiment is intended to indicate that a particular feature, structure, or characteristic described in connection with the embodiment is included in at least an embodiment of the invention. The appearances of the phrase in one embodiment or an embodiment in various places in the specification are not necessarily all referring to the same embodiment.

[0026] Throughout the drawings, reference numbers are reused to indicate correspondence between referenced elements. In addition, the first digit of each reference number indicates the figure where the element first appears.

[0027] As used in this disclosure, except where the context requires otherwise, the term comprise and variations of the term, such as comprising, comprises and comprised are not intended to exclude other additives, components, integers or steps.

[0028] In the following description, specific details are given to provide a thorough understanding of the embodiments. However, it will be understood by one of ordinary skill in the art that the embodiments may be practiced without these specific details. Well known features, elements or techniques may not be shown in detail in order not to obscure the embodiments.

[0029] Turning attention to FIG. 1, a front view of a modified crankset assembly 100 in accordance with an embodiment of the present invention is shown. The crankset assembly 100 comprises of a sprocket 101 a forward-facing modified crank arm 102 and a rear facing modified crank arm 103. A viewer may perceive that the forward-facing modified crank arm 102 has an elongated body with a first end 104 a second end 105 an axel hole opening 106 at the first end 106 and a threaded pedal hole 107 at the second end 105. The rear facing modified crank arm 103 also has an elongated body with a first end (not shown) a first end 108 an axel hole opening (not shown) at the second end (not shown) and a threaded pedal hole 109 at the second end 108. The forward-facing modified crank arm 102 and the rear facing modified crank arm 103 are connected by an axel connector 110 which runs through the center of the sprocket 101 thereby connecting the entire crankset assembly 100.

[0030] In the embodiment depicted, a viewer may perceive that the second end 105 of the forward-facing modified crank arm 102 is bent upward from the centerline axis of the elongated body forward facing modified crank arm 102. A viewer may also perceive that the second end 108 of the rear facing modified crank arm 103 is bent upward from the centerline axis of the elongated body of the rear facing modified crank arm 104.

[0031] In FIG. 2 an illustrative front view of a modified crankset assembly in accordance with an embodiment of the present invention is shown. A viewer may perceive the directional relation of the forward-facing modified crank arm 102 and the rear facing modified crank arm 103 in relation to the position and directional relation of a standard forward facing crank arm 201 and standard rear facing crank arm 202.

[0032] In FIG. 3 a perspective detached view of a modified crankset assembly 100 in accordance with an embodiment of the present invention is shown. In the embodiment depicted, a viewer may perceive that the axel 303 is removably connected to the axel hole opening 303 of the rear member 301 of the rear facing modified crank arm 103 and to the axel hole opening 106 of the forward facing modified crank arm 102.

[0033] FIG. 4 shows an angled front view of a modified crankset assembly 100 in accordance with an embodiment of the present invention. In the embodiment depicted, a viewer may perceive that the centerline axis 401 of the threaded pedal hole 107 of forward-facing modified crank arm 102 is approximately 10 degrees higher than the centerline axis of the axel hole opening 106 of the forward-facing modified crank arm 102. A viewer may also perceive that the centerline axis 402 of the threaded pedal hole 109 of the rear facing modified crank arm 103 is approximately 10 degrees lower than the centerline axis of the axel hole opening 302 (not shown) of the rear facing modified crank arm 103.

CONCLUSIONS, RAMIFICATIONS, AND SCOPE

[0034] Although the present invention has been described with a degree of particularity, it is understood that the present disclosure has been made by way of example and that other versions are possible. As various changes could be made in the above description without departing from the scope of the invention, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be illustrative and not used in a limiting sense.
