Benefits of technology

[0025]In some embodiments, an archery bow kit comprises a riser and opposed limbs. Each limb supports a rotatable member. At least one rotatable member comprises a body and a first cam module. The body defines a bowstring payout track and the first cam module defines a power cable take-up track. The kit includes a second cam module that is suitable for replacing the first cam module. Each of the cam modules

Problems solved by technology

The main short coming of this concept is that each module only provides a single draw force profile capability; therefore it would require a multitude of different designed modules to cover all of the normal draw weight and draw length combinations encountered in market place.
However, the '374 concept is even more

Embodiment Construction

[0055]While this invention may be embodied in many different forms, there are described in detail herein specific embodiments of the invention. This description is an exemplification of the principles of the invention and is not intended to limit the invention to the particular embodiments illustrated.

[0056]For the purposes of this disclosure, like reference numerals in the figures shall refer to like features unless otherwise indicated.

[0057]The archery bow concept described herein presents a new dimension in cam design that incorporates the use of a limited number of adjustable cam modules to provide a wide variety of compound bow offerings.

[0058]FIG. 1 shows an embodiment of a bow 10 that comprises a riser 12 that supports a first limb 14 and a second limb 16. Each limb 14, 16 is attached to the riser 12 with a fastener 15 (e.g., limb bolt), and may also be held by a limb cup 17. The first limb 14 supports a first rotatable member 20 and the second limb 16 supports a second rotat...

Abstract

A modular cam system for an archery bow or crossbow includes swappable cams that change the maximum draw weight of the archery bow or crossbow. Moreover, the modular cams can be affixed to a rotatable member in a number of orientations to set the desired draw length without changing the limbs, tightening or loosening limb bolts, or disassembling the bow. Further, the maximum draw weight of the bow remains substantially similar throughout a large portion of the draw length adjustment for a specified cam module.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This Application claims priority to U.S. Provisional Application No. 61 / 539,885, filed Sep. 27, 2011, the entire contents of which are hereby incorporated by reference.BACKGROUND OF THE INVENTION[0002]This invention relates generally to archery bows and more specifically to compound bows having cam adjustability.[0003]Various types of compounding archery bows are generally known in the art. Compounding archery bows generally include a plurality of rotatable members, at least one of which comprises a cam. The cam desirably provides for a reduction in the draw weight when the bow is fully drawn, allowing an archer to hold the bow in a drawn position with less fatigue.[0004]Some compounding bows include at least one rotatable member having a cam, wherein at least a portion of the cam is either adjustable with respect to the rest of the rotatable member or can be removed entirely and replaced with another cam module having a different shape.[...
