In at least one embodiment, a crossbow comprises a stock defining a shooting axis and a bow portion comprising a bowstring and a cable. The stock comprises an aperture formed therein and the cable extends through the aperture. A surface of the aperture biases the cable in a direction lateral to the shooting axis. At least a portion of the surface is oriented non-parallel to the shooting axis.

A toy projectile launcher that launches projectiles with elastic elements. Each elastic element is designed to be easily replaced on the projectile launcher. Each replaceable elastic element has two ends. An anchor block is provided that receives and retains at least one of the two ends. The anchor block is received within an anchor receptacle. A locking mechanism is used that selectively locks the anchor block within the anchor receptacle. The elastic elements extend from the anchor receptacles and present projectile engagement structures that can be hooked by the toy projectile being launched.

A weight for an archery bowstring comprises a tubular shape defining an internal cavity. The weight can comprise a single piece of material. The weight desirably frictionally engages a bowstring and has the same shape before and after installation. The weight comprises a continuous structure surrounding the bowstring that will not become detached.

A string loop tensioning pliers device includes a first member comprising a first handle and a fixed arcuate jaw comprising an upper jaw and a lower jaw. The lower jaw has an arcuate claw end and the upper jaw has a first lateral dowel pin end and three in-line lateral facing beveled prongs. A second member comprises a second handle pivotally connected above the first member and includes a notched end opposite the handle and a second lateral dowel pin configured to join with the middle prong when the pliers are closed. A method for using the disclosed tensioning pliers includes tensioning a string knotted to the bowstring, spreading a loop created on the bowstring and tensioning the created loop by inserting the middle prong joined with the second lateral dowel through the formed loop and squeezing the pliers to separate the middle prong and the second lateral dowel.

The present invention comprises a two-track cam assembly wherein the cam assembly has a bowstring component for housing the bowstring and a power cable component that allows for the take up and let out of the power cable on opposing ends of the power cable component, effectively creating a two-track cam assembly. The efficiency rating of the device achieves 95.8%. The cam assembly can come in a unitary or modular form and further each component (i.e. the bowstring or power cable component) can be in a circular or non-circular form.

An improved nocking system for archery wherein the bow string is magnetically held within a U-shaped channel in the nock attached to the rearward end of an arrow.
摘要:
A bow energy transfer system includes a pair of helically wound springs positioned on the bowstrings on either side of the bowstring nock point; the springs are secured to the bowstring with a serving thread wound between the individual coils into contact with the bowstring. The springs flex perpendicular to their longitudinal axes during discharge of the bow causing energy to temporarily be stored in the flexed spring to be returned to the arrow or bolt later in its discharge.
