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.

Description

RELATED INVENTION[0001] This application is a continuation-in-part of provisional application Serial No. 60 / 223,996, filed Aug. 9, 2000.[0002] 1. FIELD OF THE INVENTION[0003] The present invention relates to archery equipment, including crossbows. In particular, it relates to improving performance of archery equipment and especially crossbows, by absorbing recoil energy (i.e., vibrations and noise) without sacrificing projectile velocity.[0004] 2. DESCRIPTION OF THE PRIOR ART[0005] Archery bows are available in a variety of forms. Long bows, recurve bows, compound bows and other bows are all basically intended to propel an arrow through the flecture of limbs that transfer the stored energy through such flecture to the arrow through a bow string. A recurve bow may incorporate a rigid handle section to which an opposing pair of flexible limbs are secured in a manner unique to recurve bows and familiar to those in the archery industry. Similarly, a compound bow is provided with a rigid...

AI Technical Summary

Benefits of technology

[0028] In spite of the above alleged solutions to the problem, there is still a need for a damping device to be incorporated into a bow to absorb excess energy, thereby reducing hard shock, noise and bow vibration.

Problems solved by technology

However such string silencers did not have an effect on vibration and they reduced projectile velocity.

The problem with archery equipment, namely, the leftover energy resulting from the firing of archery equipment, is analogous to that which existed in the recoil of firearms.

The vibration damping mechanism was said to result in significant noise reduction upon firing of the crossbow.
