发明名称 Archery bow press and method for compressing an archery bow using collectively connected bow limb supports
摘要 An archery bow/crossbow press and method provides operation to various bow designs including bows with past parallel limbs or having limbs with sharp curvatures using collectively connected bow limb supports to engage the outer face of a bow limb for compression; each bow limb support configured with at least one upper and at least one lower support arm wherein each support arm comprises bow limb contact areas that may include various shapes adaptable to engage a bow limb or limb components; each support arm may be positioned against a bow limb independently or collectively with each other; and, when the bow limb supports are positioned collectively on the bow they may be the sole contact of the bow press during the pressing operation.

主权项 1. In an archery bow press comprising a frame supporting a pair of opposing arm members defining a bow limb receiving location between them and movable toward and away from each other with a drive mechanism to press opposing limbs of a bow, a collective support on each arm member for applying force to a respective bow limb to compress the bow, each collective support comprising: a central hub configured to mechanically mount the collective support to the arm member; an upper bow limb support arm and a lower bow limb support arms fixed to the central hub as a single unified structure; a bow limb contact area incorporated into each of the upper and lower bow limb support arms for simultaneously contacting the outer curved face of the respective bow limb; the upper and lower bow limb support arms set in a fixed position on the central hub, and projecting outward from the central hub in a common plane at an acute angle relative to one another to terminate at the bow limb contact areas, the upper and lower bow limb support arms configured to straddle an arc corresponding to a linear length of an outer curved face of the bow limb; the upper and lower bow limb support arms defining a space between them a distance located outwardly from the central hub adequate to flex and hold therebetween the linear length portion of the outer curved face of the bow limb between the bow limb contact areas anywhere along the bow limb's linear length, when compressive force is applied by the bow limb support arms to the bow limb, allowing the bow limb to flex slightly into the space in a manner that increases a coefficient of friction between the outer curved face of the bow limb and the bow limb contact areas on the bow limb support arms and simultaneously holding the bow limb securely to the collective support using only the outer curved face of the bow limb and preventing the bow limb from flattening and losing contact with the bow limb contact areas, such that the upper and lower support arms of the collective supports are the only contact the bow has with the press during pressing.
