Recoil energy dissipation system for archery equipment

Abstract

A bow, preferably a crossbow, is provided herein. The bow is provided with a recoil energy dissipation system. When applied to a crossbow, the crossbow comprises a stock member including a barrel at a forward portion thereof, the barrel being configured for supporting an arrow for firing of the crossbow. A riser block assembly is provided at a forward end of the barrel, the riser block assembly supporting first and second bow limbs extending outwardly, the first and second bow limbs carrying a bowstring between the outward tips thereof, and extending transversely to the barrel. The stock member further has a trigger mechanism associated therewith selectively to hold and release the bowstring from a cocked position in which the bowstring is drawn in a direction away from the first and second bow limbs to tension the bow limbs. The recoil energy dissipation mechanism includes an associated flexible attachment arm which is secured at one end to the riser block assembly and which extends from the riser block assembly to each bow limb, and an energy-absorbing member which is secured to each flexible arm and is in contact with an associated bow limb, thereby to reduce vibrations and noise without sacrificing significant projectile velocity.
