A crossbow may include a main beam and a bow mechanism having a pair of outwardly extending bow limbs, a pair of bowstring wheels, a bowstring and at least one power cord that extends between the bow limbs. The crossbow may also include a traveling trigger mechanism and a drawing mechanism. The traveling trigger mechanism may hold the bowstring in the un-cocked condition. The drawing mechanism may then be operated to move the traveling trigger mechanism and thus the bow string from the un-cocked condition to a cocked condition.

A crossbow includes a stock defining a projectile axis, a drawstring configured to move along the projectile axis between an undrawn position and a drawn position, the undrawn position defining a first power stroke end, the drawn position defining a second power stroke end, and a scope rail mount including a first support and a second support, the first support coupled to the stock at a first mount location positioned rearward of the first power stroke end, the second support coupled with the stock at a second mount location positioned rearward of the first mount location and forward of the second power stroke end.

Systems and apparatuses include a crossbow having a stock, a vertical limb, a hub, a mid support. A projectile plane defines a projectile axis within the projectile plane. The vertical limb includes a first end and a second end. The first end is coupled to the stock by a main support positioned vertically below the projectile axis. The second end is positioned vertically above the projectile plane. The hub is rotatably mounted to the stock and includes a first portion and a second portion positioned axially between the stock and the first portion. The first portion is operatively coupled with the vertical limb. The mid support is coupled to the stock. The mid support is configured to support the vertical limb between the first end and the second end.

A bowstring release is described herein. The bowstring release has, in an embodiment, a release body and a hook for holding a bowstring. The bowstring release includes a trigger coupled to the release body, and the trigger has a roller for operation of the release.

The present invention relates to methods and apparatus that may enable the folding of a multi-point compression powered archery bow. More specifically, the present invention relates to a foldable archery bow, powered by multiple compression devices, wherein the upper limb and the lower limb may be drawn independently and released together. In some aspects, the bow may be adjustable for draw weight, draw length, and draw weight let-off at full draw length in a fixable frame that may be folded and unfolded.

The projectile launcher includes a riser base, an elongate barrel assembly attached to the riser base, a crank mechanism attached to the back of the barrel assembly, a trigger assembly, and an internal bow assembly mounted to the riser base. The crank assembly includes a rotatable crank for selective reciprocation of a cocking carriage riding inside a rail system in the barrel assembly. The cocking carriage selectively engages a projectile nock carriage riding within the rail system to push the nock carriage into a cocked position. The internal bow assembly includes vertically spaced upper and lower resilient bow arms and a system of pulleys and cables interconnecting the bow arms and the nock carriage. Cocking to the nock carriage flexes the bow arms in preparation for placement and firing of a projectile. The working components of the projectile launcher are enclosed by a covering to protect the user.

A bow for launching a projectile has a stock extending along a longitudinal axis and adapted for receiving the projectile. A biasing element has a traveling end and is biased in a direction generally parallel to the longitudinal axis. A launcher has a traveling end adapted to engage the projectile for propelling the projectile in a forward direction. A launch system is mounted to the stock and has a leveraging component, the traveling end of the biasing element being coupled to the traveling end of the launcher through the launch system. Movement of the traveling end of the biasing element at a first rate from a cocked position to a released position during launch causes forward movement of the traveling end of the launcher at a second rate higher than the first rate, thereby launching the projectile from the stock.

An electronic recurve bow includes an electronic control riser having a body configured to be held in a hand of a user, wherein the body includes a power supply configured to provide operating power, a user input configured to receive a user selection of a draw weight for the bow, a controller configured to receive the user selection of the draw weight from the user input and configured to output electronic control signals in response to the user selection of the draw weight, and a pair of electronically controlled laminated electroactive polymer limbs coupled to the electronic control riser, wherein each limb comprises a base material and an electronically controllable material, wherein the electronically controllable material comprises a material having a variable stiffness in response to the output electronic control signals.

In some embodiments, an archery bow is configurable between a first draw orientation and a second draw orientation. The bow comprises a limb and a limb support. The limb defines an unsupported length in either orientation, wherein the unsupported length of the limb is less in the second draw orientation than in the first draw orientation.
