Patent Application
20210341252
This invention relates to archery bows, which are known in the art and are used to launch projectiles, such as arrows.
In an archery bow, the energy that is transferred to the arrow during firing ultimately comes from the archer. The process of drawing the bow transfers energy from the archer to the bow. The stored energy is largely transferred to the arrow, but some energy is lost due to various inefficiencies in the bow.
There remains a need for novel archery bow designs that provide benefits in efficiency and accuracy over prior designs.
All US patents and applications and all other published documents mentioned anywhere in this application are incorporated herein by reference in their entirety.
Without limiting the scope of the invention a brief summary of some of the claimed embodiments of the invention is set forth below.
