Abstract
An improved archery bow press used to safely relieve tension in the bow string of a short limbed compound archery bow. Slidable brackets are retained to a horizontal beam and retain pivot arms to the beam. Brackets slidable along each of the pivot arms may be locked in place. Each pivot arm includes a bearing member which abuts a limb of a compound bow. A jack is mounted to the beam to raise and lower link members connected to the pivot arms. The link members are adjustable in length. Markings are provided on the adjustable members so that adjustments to those elements can be made based on data in a table correlating settings for specific compound bows. Safety latches lock the bow limbs to the slidable brackets. A method for presetting the press is provided.
Claims16
Apparatus to selectively deflect limbs of an archery bow, the invention comprising
- an elongate generally horizontal beam,
- first and second brackets slidably retained to the beam,
- the first and second brackets slidable along the beam at equal rates in opposing directions,
- each of the first and second brackets comprising an elongate support member extending laterally therefrom,
- each elongate support member engageable with an inside surface of a one of the limbs of the archery bow,
- a first pivot arm hinged to the first bracket,
- a second pivot arm hinged to the second bracket,
- each elongate support member having an axis substantially perpendicular to a plane defined by the pivot arms and the elongate beam,
- a first support bracket retained to the first pivot arm and selectively slidable therealong,
- a second support bracket retained to the second pivot arm and selectively slidable therealong,
- a limb engaging member supported on each support bracket to touchingly engage an outside surface of one of the limbs of the archery bow and to selectively urge the one of the limbs of the archery bow toward the other limb,
- a first elongate link hinged to the first support bracket,
- a second elongate link hinged to the second support bracket,
- an extendible length member disposed at substantially a midpoint of the horizontal beam,
- the extendible length member having a selectively extensible member,
- the first and second links hinged to the extensible member,
- each limb engaging member comprises a cylindrical rod,
- each cylindrical rod being elongate and having a longitudinal axis substantially perpendicular to the plane defined by the pivot arms and the elongate beam,
- each cylindrical rod having a free end,
- a limb support cradle selectively receivable on each of the cylindrical rods,
- each limb support cradle including a cylindrical opening for receiving the cylindrical rod on which the limb support cradle is receivable,
- each limb support cradle nonrotatable about the cylindrical rod on which it is received,
- each limb support cradle including a bearing surface touchingly engageable with an outer surface of one of the limbs of the bow.
In a bow press having an elongate beam, a pair of pivot arms retained to the beam and selectively moveable therealong, the pivot arms pivotable upon the beam, each pivot arm having an elongate link member hinged thereto, the elongate link members each being selectively joined along distal ends thereof to an extensible section of a telescoping member, the improvement comprising
- each link member including a plurality of attachment points thereon,
- each attachment point identified by an individual identifier specific to the attachment point,
- each individual identifier marked on the link member adjacent each attachment point of the plurality of attachment points,
- the beam comprising indicia thereon,
- the indicia marking locations along the beam for location of at least one of the pivot arms therealong,
- the indicia fixed along at least a first half of the beam,
- each pivot arm including indicators therealong,
- the indicators marking specific points along the pivot arm for location of a limb support bracket therealong,
- each indicator marked on each pivot arm adjacent a specific one of the specific points along the pivot arm,
- each link member hinged to one of the limb support brackets,
- the extensible section of the telescoping member including indexing marks affixed therealong,
- whereby the bow press may be preset based upon a type or model of bow to be pressed,
- each pivot arm supports a limb engaging member thereon,
- each limb engaging member selectively supporting a limb cradle thereon,
- each limb cradle comprising a pair of limb cradle members,
- each limb cradle member including a cylindrical opening,
- the cylindrical opening including internal splines thereabout,
- each limb engaging member comprising a cylindrical rod,
- the cylindrical rod having external splines thereon, the external splines surrounding a longitudinal segment of the cylindrical rod,
- orientation markings disposed on the limb cradle,
- the orientation markings disposed adjacent the cylindrical opening of each limb cradle member,
- at least one index mark on the limb engaging member,
- the at least one index mark fixed to the cylindrical rod and aligned with a one of the splines thereof,
- wherein each limb cradle may be oriented on the limb engaging member at a predetermined orientation by alignment of the at least one index mark with a selected one of the orientation markings on the limb cradle.
