A bow stabilizer according to the present invention includes a body for attachment to the bow which defines an internal chamber. A guide rod is supported by the body within the internal chamber. The guide rod carries a movable part and a pair of biasing members arranged to apply opposing biasing forces to the movable part. A pair of stabilizer arms are removably connected to the movable part and extend external to the internal chamber through openings in the body. Each stabilizer arm carries a removable stabilizer weight. The movable part moves forwardly and rearwardly along the guide rod against the biasing forces of the biasing members, carrying the stabilizer arms forwardly and rearwardly within their respective openings, to counteract the bow vibration created by launching an arrow.
In one embodiment, a bow stabilizer for an archery bow has an elongated member having a near end for attachment to an archery bow and a distal end, the elongated member having a length L, and a weight attached to the elongated member proximate the distal end. The center of gravity of the elongated member and weight is located within 25 percent of length L from the distal end of the elongated member. In another embodiment, the stabilizer has an elongated member having a near end for attachment to an archery bow, a distal end, and a weight attached to the elongated member proximate the distal end. The natural frequency of the first bending mode of the elongated member and weight is at least 20 Hz. In a further embodiment, the stabilizer has an elongated member having a near end for attachment to an archery bow and a distal end, and a weight attached to the elongated member proximate the distal end. The weight has a first mass M1 which is at least 1.2 times a second mass M2 of the elongated member.
An archery bow stabilizer includes a first weight body and a second weight body. One of the weight bodies has structure (such as a threaded stem attached to a central longitudinal axis thereof or a threaded bore along a central longitudinal axis thereof cooperative with a threaded set screw) for engaging it to an archery bow. The other weight body has structure (such a threaded bore at central longitudinal axis thereof cooperative with the threaded stem of the other weight body or a set screw having a first end portion and a second end portion, the first end portion engaging the threaded bore of one of the weight bodies and the second end portion engaging the threaded bore of the other weight body) to releasably connect the weight bodies to each other in a single longitudinal axially aligned plane intersecting the bow and disposing the bow between the weight bodies to thereby form a stabilizer assembly having sufficient mass to provide inertia resistance for stabilizing the bow against movement.
A bow construction (10) adapted for use in combination with a wheelchair (200) wherein the bow construction (10) includes a hollow cylindrical riser member (20) provided with a pair of bow limb members (30) and a pair of transverse tubular elements (24) (25) that serve as a bow rest and bow sight respectively; wherein, the bow riser member (20) is slidably disposed on and vertically adjustable with respect to an elongated cylindrical spike member (40) that is adapted to be releaseably attached to one of the foot rests (201) of a wheelchair (200).
