Abstract
Certain embodiments of the present disclosure describe a compound archery bow that has a rigid vertical riser structure. At least one flexible limb extends rearward from the vertical riser structure. One end of the flexible limb is secured to the cable arrangement of the compound bow, so that when the bowstring is drawn, the flexible limb is flexed toward the cams of the bow. As the flexible limb is bent, it stores energy that is transferred to an arrow when the bowstring is released.
Claims20
An archery bow, comprising:
- a rigid vertical riser assembly with rearward extending portions;
- upper and lower rotatable elements wherein each of said rotatable elements are mounted to respective rearward tip sections of said rearward extending portions;
- at least one flexible limb including a base wherein the base of said flexible limb is mounted to said vertical riser assembly;
- a cable arrangement defining a bowstring extending between said upper and lower rotatable elements, said bowstring forming upper and lower cable portions which each form a medial portion respectively trained around said upper and lower rotatable elements so that said bowstring extends directly between the upper and lower rotatable elements,
- said cable arrangement further including a return cable portion extending at one end from one of said upper and lower rotatable elements with an opposing end secured to said at least one flexible limb, said return cable portion extending directly between one of said upper and lower rotatable elements and said at least one flexible limb;
- and
- an area defined between said vertical riser assembly and said bowstring;
- wherein said flexible limb extends rearward from said rigid vertical riser assembly into the area such that said flexible limb is positioned entirely within said area;
- and,
- wherein drawing said bowstring applies force to said flexible limb causing said limb to bend and store energy.
7 more elements
An archery bow, comprising:
- a rigid vertical riser assembly including an upper portion and a lower portion;
- a rigid non-flexing portion extending rearward from the upper portion of said vertical riser assembly;
- a rigid non-flexing portion extending rearward from the lower portion of said vertical riser assembly;
- upper and lower rotatable elements mounted to said respective upper and lower rearward extending portions;
- at least one flexible limb with a base mounted to said vertical riser assembly wherein said flexible limb extends rearward from said vertical riser assembly;
- a cable arrangement defining a bowstring, said bowstring forming upper and lower cable portions which each form a medial portion respectively trained around said upper and lower rotatable elements so that said bowstring extends directly between the upper and lower rotatable elements and further including a return cable portion extending at one end from one of said upper and lower rotatable elements directly to said at least one flexible limb;
- wherein an opposing end of said return cable portion is secured to said flexible limb;
- and,
- wherein drawing said bowstring applies force to said at least one flexible limb causing said limb to bend and store energy.
6 more elements
An archery bow, comprising:
- a rigid vertical riser assembly defining a vertical axis and including at least one non-bending rearward extending portion defining a longitudinal axis;
- upper and lower rotatable elements mounted to said vertical riser assembly;
- a cable arrangement defining a bowstring, said bowstring forming upper and lower cable portions which each form a medial portion respectively trained around said upper and lower rotatable elements so that said bowstring extends directly between the upper and lower rotatable elements;
- an internal angle toward the bowstring defined by the longitudinal axis of said rearward extending portion and the vertical axis of said vertical riser assembly;
- at least one flexible limb wherein the base of said limb is attached to said riser assembly and wherein said flexible limb extends rearward within said internal angle;
- wherein said cable arrangement further includes a return cable portion extending at one end from at least one of said upper and lower rotatable elements with an opposite opposing end of said return cable portion attached to said flexible limb said return cable portion extending directly between one of said upper and lower rotatable elements and said at least one flexible limb;
- and,
- wherein drawing said bowstring applies force to said flexible limb causing said limb to bend and store energy.
