Abstract
An archery bow with elastic limbs extending outwardly from the handle, constructed so that portions of these limbs twist around the limb axis to a lower moment of inertia configuration during the draw, storing additional torsional strain energy and also altering the force-draw characteristic of the bow in a favorable way.
Claims31
An archery bow comprising a pair of longitudinal extending limbs and a pair of divided sections, said divided sections comprising a pair of substantially axisymmetric, parallel elements, said parallel elements being non-planar, wherein said divided sections longitudinally divide a portion of said limbs.
An archery bow comprising a pair of longitudinally extending limbs;
- wherein said limbs comprise a means for storing energy by torsional and rotational deformation.
An archery bow comprising;
- a) a pair of longitudinally extending limbs;
- and
- b) a bowstring attached to the tips of said limbs, wherein a portion of said limbs comprise a limb structure which stores energy, when said bowstring is drawn, by torsional and rotational deformation.
A limb for an archery bow, said limb comprising a divided section, said divided section comprising a pair of substantially axisymmetric, parallel elements, said parallel elements being non-planar, wherein said divided sections longitudinally divide a portion of said limb.
A limb for an archery bow, wherein said limb comprises a means for storing energy by torsional and rotational deformation.
