a pair of linkage brackets that slide along each of the pivot arms;
a pair of links pivotally connecting the linkage brackets to an actuator mechanism that is adapted to simultaneously move the links toward and ways from the support rail; and
linkage bracket support members attached to each of the linkage brackets adapted to engage outside surfaces of the bow limbs, the linkage bracket support members adapted to simultaneously deflect the bow limbs generally away from the support rail and toward the center portion in response to the actuator mechanism moving the links ways from the support rail.
2. The bow press of claim 1 wherein the pair of opposing support members comprise an inside support members moveably attached to each of the pivot arm brackets and an outside support member.
3. The bow press of claim 2 wherein the inside support members include ratcheting mechanisms that permit free movement toward the outside support members, but restricts movement way from the outside support members.
4. The bow press of claim 3 comprising a release that disengages the ratcheting mechanisms so the inside support members can be displaces away from the outside support members.
5. The bow press of claim 1 wherein the pair of opposing support members comprise inside support members attached to each of the pivot arm brackets and outside support members releasably attached to the pivot arm brackets.
6. The bow press of claim 1 comprising a drive mechanism adapted to simultaneous move the pivot arm brackets toward or away from the center portion of the support rail to compensate for the size of the bow.
7. The bow press of claim 1 comprising a ratcheting mechanism engaged with the links that is adapted to adjust a distance between the linkage brackets and the actuator mechanism.
8. The bow press of claim 1 comprising an adjustable locking mechanism attaching the links to the actuator mechanism, the locking mechanism comprising a first position that lock the links in position, a second position that permits the links to slide freely in the locking mechanism, and a third position that permits ratcheting between the links and the locking mechanism.
9. The bow press of claim 1 wherein at least one locking mechanism attaches the links to the actuator mechanism, the locking mechanism comprising:
center pins biased to releasably engage with apertures in the links; and
protrusions on the center pins adapted to retain the center pins in a disengaged relationship with the links.
10. The bow press of claim 1 comprising a biasing mechanism adapted to suspend the pivot arms in a neutral position above the support rail.
11. The bow press of claim 1 wherein the linkage bracket support members comprise rotating support members.
12. The bow press of claim 11 wherein the rotating support members comprise one of a wheel, a cam, a crescent shaped structure.
13. The bow press of claim 1 wherein the linkage bracket support members comprise:
at least two freely rotating wheels attached to each of the linkage brackets by shafts; and
adjustment mechanisms adapted to adjust a separation between the rotating wheels along the shafts.
14. The bow press of claim 1 wherein the linkage bracket support members are adapted to engage with the bow limbs proximate bow limb cam axes.
15. A bow press for deflecting the bow limbs attached to a riser of a bow, the bow press comprising:
a support rail including a longitudinal axis and a center portion;
a pair of pivot arms each pivotally attached to pivot arm brackets that slide along the support rail on opposite sides of the center portion;
support members attached to the pivot arm brackets that are adapted to engage the bow limbs and/or the riser;
a pair of linkage brackets that slide along each of the pivot arms;
a pair of links pivotally connecting the linkage brackets to an actuator mechanism that is adapted to simultaneously move the links toward and ways from the support rail;
a ratcheting mechanism engaged with the links that is adapted to adjust a distance between linkage brackets and the actuator mechanism, the ratcheting mechanism permitting the links to be freely moved away from the support rail, but restricts movement of the links toward the support rail; and
linkage bracket support members attached to each of the linkage brackets adapted to engage outside surfaces of the bow limbs, the linkage bracket support members adapted to simultaneously deflect the bow limbs generally away from the support rail and toward the center portion in response to the actuator mechanism moving the links ways from the support rail.
16. The bow press of claim 15 wherein the ratcheting mechanism comprises a first position that lock the links in position, a second position that permits the links to slide freely in the locking mechanism, and a third position that permits ratcheting between the links and the locking mechanism.
17. The bow press of claim 15 wherein the ratcheting mechanism comprising:
center pins biased to releasably engage with apertures in the links; and
protrusions on the center pins adapted to retain the center pins in a disengaged relationship with the links.
18. The bow press of claim 15 wherein the support members comprise an inside support members moveably attached to each of the pivot arm brackets and an outside support member.
19. The bow press of claim 18 wherein the inside support members include ratcheting mechanisms that permit free movement toward the outside support members, but restricts movement way from the outside support members.
20. The bow press of claim 15 comprising a biasing mechanism adapted to suspend the pivot arms in a neutral position above the support rail.
21. The bow press of claim 15 wherein the linkage bracket support members comprise:
at least two freely rotating wheels attached to each of the linkage brackets by shafts; and
adjustment mechanisms adapted to adjust a separation between the rotating wheels along the shafts.
22. A bow press for deflecting the bow limbs attached to a riser of a bow, the bow press comprising:
a support rail including a longitudinal axis and a center portion;
a pair of pivot arms each pivotally attached to pivot arm brackets that slide along the support rail on opposite sides of the center portion;
support members attached to the pivot arm brackets that are adapted to engage the bow limbs and/or the riser;
a pair of linkage brackets that slide along each of the pivot arms;
