Abstract

Lever Regulated Compound Bow uses multiple groove modules on the limb tips to spool bowstring and cables to provide desired energy storage and nock travel, while simultaneously using a lever to regulate cam synchronization, using split cable harnesses to deter limb twist, and lever blocking draw stop means.

Claims

exact text as granted — not AI-modified
1 . a.) An archery bow having a handle, a first and second limb attached to ends of said handle,
 b.) rotating modules mounted on ends of said limbs, said rotating modules having multiple grooves,   c.) a bowstring attached to said modules,   d.) a rotatable lever mounted on a support extending from said handle between said rotating modules, and   e.) a cable extending from one limb to the other limb, said cable means extending between said limbs, being acted on by said lever when drawing said bow to compress said limbs.   
   
   
       2 . The bow of  claim 1  wherein the multiple grooves are concentric about axles of said modules. 
   
   
       3 . The bow of  claim 1  wherein the multiple grooves are eccentric about axles of said modules. 
   
   
       4 . The bow of  claim 1  wherein the multiple grooves consist of one concentric groove and one eccentric groove. 
   
   
       5 . The bow of  claim 1  wherein the multiple grooves consist of one concentric and one cam groove. 
   
   
       6 . The bow of  claim 1  wherein the multiple grooves consist of one eccentric and one cam groove. 
   
   
       7 . The bow of  claim 1  wherein the multiple grooves consist of two cam grooves. 
   
   
       8 . The bow of  claim 1  wherein said cable extending from one limb to the other is attached to axles of modules on top and bottom limbs. 
   
   
       9 . The bow of  claim 1  wherein said cable extending from one limb to the other is split and attaches to ends of axles of modules outside the limbs. 
   
   
       10 . The bow of  claim 1  wherein said cable means is routed around pegs on said lever. 
   
   
       11 . a.) An archery bow having a handle, a first and second limb attached to the ends of said handle,
 b.) rotating modules mounted on the ends of said limbs, said rotating modules having multiple grooves, and   c.) a bowstring attached to said modules.   d) a cable attached to a module of one limb and extending to and attaching to said lever; and a second cable attaching to module of second limb and extending to and attaching to said lever.   
   
   
       12 . The bow of  claim 1  wherein said lever is positioned at the midpoint between said modules. 
   
   
       13 . The bow of  claim 1  wherein said lever is positioned away from the midpoint between said modules. 
   
   
       14 . The bow of  claim 1  wherein modules vary the leverage applied to the lever compressing the limbs so that peak draw weight is held through a distance of the draw. 
   
   
       15 . The bow of  claim 1  wherein modules spool bowstring and cables at a rate coupled with the leverage applied to the lever compressing the limbs so that nock travel is straight and level. 
   
   
       16 . a.) An archery bow having a handle, a first and second limb attached to the ends of said handle,
 b.) rotating modules mounted on the ends of said limbs, said rotating modules having multiple grooves,   c.) a bowstring attached to said modules,   d.) a rotatable lever mounted on a support extending from said handle between said rotating modules,   e.) first cable means extending from one limb to said lever,   f.) second cable means extending from second limb to said lever,   g.) third cable means attached to the module of one limb and extending to and attaching to said lever, and   h.) fourth cable means attached to the module of said second limb and extending to and attaching to said lever.   
   
   
       17 . a.) An archery bow having a handle, a first and second limb attached to the ends of said handle,
 b.) rotating modules mounted on the ends of said limbs, said rotating modules having multiple grooves,   c) a bowstring attached to said modules,   d.) a rotatable lever mounted on a support extending from said handle,   e.) first cable means extending from one limb to said lever is split and attaches to axles of said modules   f.) second cable means extending from said second limb to said lever, said second cable means being split and attaching to axles of said modules,   g.) third cable means attached to the module of one limb and extending to and attaching to said lever, and   h.) fourth cable means attached to the module of said second limb and extending to and attaching to said lever.   
   
   
       18 . The bow of  claim 11  wherein cable means extending from said limbs to said lever is split and attaches to axles of said modules. 
   
   
       19 . a.) An archery bow having a handle, a first and second limb attached to the ends of said handle,
 b.) rotating modules mounted on the ends of said limbs, said rotating modules having multiple grooves,   c.) a bowstring attached to said modules,   d.) a rotatable lever mounted on a support extending from said handle between said rotating modules,   e.) cable means extending between said limbs being acted on by said lever when drawing bow to compress said limbs, and   f.) draw stop means prevents movement of said lever   
   
   
       20 . The bow of  claim 19  wherein draw stop means is an integral protrusion of said lever support. 
   
   
       21 . The bow of  claim 19  wherein draw stop means is a protrusion attached to said lever support. 
   
   
       22 . The bow of  claim 21  wherein said protrusion is a screw. 
   
   
       23 . The bow of  claim 19  wherein said draw stop means is an integral protrusion of said lever. 
   
   
       24 . The bow of  claim 19  wherein said draw stop means is a protrusion attached to said lever. 
   
   
       25 . The bow of  claim 24  wherein said protrusion is a screw.
