摘要： A crossbow may comprise a safety device that provides the user a visual means other than the mechanical positioning of the various components of the crossbow to quickly and accurately determine the firing condition of the crossbow. The safety device may comprise an illuminated marker that emits a specific color of light to denote the firing condition of the crossbow. In another embodiment, the safety device may comprise a mechanical assembly that is raised and lowered to denote the firing condition of the crossbow. In yet another embodiment, the safety device may comprise an electric switch that causes an illuminated marker to emit a light or a mechanical assembly to raise or lower in order to denote the firing condition of the crossbow.

摘要： Provided is a crossbow riser that may comprise a plurality of cells defined by walls. The walls may consist essentially of a material wherein the yield tensile strength at 0.2% strain is greater than 780 MPa, and either the specific strength is greater than 200 kN·m/kg, or the density is less than 6.0 g/cc. The cells may collectively define a first volume. The walls may collectively define a second volume. The ratio of the first volume to the second volume may be greater than 1.5.

摘要： One or more techniques and/or systems are disclosed for a bowstring drawing mechanism for drawing and controllably releasing a crossbow bowstring comprises a clutch mechanism. The clutch mechanism protects the bowstring drawing mechanism from damage caused by over-cranking and allows the user to controllably release the bowstring from the drawn position.

摘要： One or more techniques and/or systems are disclosed for a nock device that may be used on an arrow. A top portion a nock device can comprise one or more pairs of string guide impression on its top surface, where the respective one or more pairs of string guide impressions may be symmetrically arranged on the top surface, with respect to each other. A first pair of string guide impression can be disposed along a first bisecting line on the top surface, and, if present, a second pair of string guide impressions can be disposed along a second bisecting line on the top surface. The respective one or more pairs of string guide impression can be configured to receive a bowstring, where the first pair may receive the bowstring in a first orientation, and the second pair, if present, may receive the bowstring in a second orientation.

摘要： A crossbow may include a main beam; a compound bow assembly mounted to the main beam; and, a trigger mechanism mounted to the main beam for use in holding a bowstring in a cocked position. The crossbow may include wheels at opposite ends of the bow that operatively receive the bowstring. The wheels may be separated by a wheel distance (WD) when the crossbow is in an un-cocked position. The crossbow may also have a power stroke distance (PD) and the ratio WD/PD may be less than 2.0.

摘要： An angled grip may allow a wrist, a palm, and a forearm of an associated user to be substantially aligned when aiming or discharging a weapon. The angled grip may be selectively attachable to the weapon and may comprise a ball joint mount for operatively connecting the angled grip to a weapon. The ball joint mount may comprise a shaft and a spherical portion. The shaft can be fixedly received in a stock of the weapon. The spherical portion can be rotatably received in a socket formed in an end of the angled grip.
