Abstract

A crossbow including a center rail including a bottom portion, a proximal end, and a distal end positioned opposite the proximal end, the center rail at least partially defining a crossbow length and a midpoint plane intersecting a horizontal midpoint of the crossbow, a riser extending horizontally from the distal end, one or more limbs coupled to the riser, and a trigger extending from the bottom portion of the center rail and positioned within ten percent of the crossbow length from the midpoint plane.

First claim

What is claimed is:

1 . A crossbow, comprising:
a drawstring repositionable between a drawn configuration and a released configuration; a center rail including a bottom portion, a proximal end, and a distal end positioned opposite the proximal end, the center rail at least partially defining a crossbow length and a midpoint plane intersecting a horizontal midpoint of the crossbow; a riser extending horizontally from the distal end; one or more limbs coupled to the riser; a trigger extending from the bottom portion of the center rail and positioned within ten percent of the crossbow length from the midpoint plane; a stock coupled to the center rail and including an integral cheek rest, the integral cheek rest positioned at the proximal end; a string carrier including a safety, a rotatable sear, and a drawstring catch, the string carrier slidably engaged within the center rail wherein the safety, the rotatable sear, and at least a portion of the drawstring catch are positioned vertically below the integral cheek rest with the drawstring in the drawn configuration, the safety repositionable between a first position and a second position, the safety including a shoulder and an actuator, the shoulder configured to retain a portion of the rotatable sear in the first position and disengage with the rotatable sear in the second position, the actuator extending from a side of the string carrier, the string carrier defining an arrow capture recess, the arrow capture recess extending towards a proximal end of the string carrier; a trigger pawl operatively coupled to the trigger and positioned vertically below the integral cheek rest; and a cocking mechanism including a rotating member, the rotating member positioned vertically below the integral cheek rest and coupled to a flexible tension member, the flexible tension member coupled to the string carrier and extending above the center rail; wherein, during operation of the crossbow, the string carrier engages the drawstring and the cocking mechanism winds the flexible tension member onto the rotating member to move the drawstring from the released configuration to the drawn configuration; wherein, with the drawstring in the drawn configuration, the trigger pawl is configured to contact the rotatable sear to cause the string carrier to release the drawstring upon actuation of the trigger.

2 . The crossbow of claim 1 , further comprising:
a trigger linkage extending between the trigger pawl and the trigger; wherein the string carrier further comprises a spring and a dry fire lockout, the spring configured to move the dry fire lockout towards the drawstring catch, the rotatable sear configured to retain the dry fire lockout, the dry fire lockout configured to retain the drawstring catch, the drawstring catch configured to receive the drawstring; and wherein the drawstring catch is coupled to the center rail, and the trigger is positioned forward of the drawstring catch with the drawstring in the drawn configuration.

3 . The crossbow of claim 2 , wherein at least a portion of the drawstring engages with the drawstring catch when the drawstring is received within the drawstring catch, wherein the rotatable sear is configured to engage with the drawstring catch to selectively actuate the drawstring catch.

4 . The crossbow of claim 1 , further comprising a grip coupled to the center rail and positioned adjacent the trigger, and
wherein at least a portion of the grip is aligned with the midpoint plane.

5 . The crossbow of claim 1 , further comprising an upper roller within the arrow capture recess.

6 . The crossbow of claim 1 , wherein the one or more limbs includes two limbs coupled to opposite sides of the riser, and
wherein the two limbs extend toward the proximal end.

7 . The crossbow of claim 1 , wherein the cocking mechanism includes a shaft defining a center point, wherein a first distance is defined between the center point of the shaft and the trigger, and wherein a second distance is defined between a center point of the rotating member and the trigger, the second distance greater than the first distance.

8 . The crossbow of claim 1 , further comprising:
a cocking handle configured to rotate the rotating member to retract the flexible tension member via a drive shaft located vertically below the integral cheek rest; and wherein the cocking mechanism slides to a retracted position in response to rotation of the cocking handle.

9 . The crossbow of claim 1 , wherein the drawstring defines an included angle less than 20 degrees when the drawstring is in the drawn configuration such that the integral cheek rest is wider than a portion of the drawstring positioned vertically below the integral cheek rest with the drawstring in the drawn configuration.

10 . The crossbow of claim 1 , further comprising:
a scope mount having a proximal end coupled to the integral cheek rest and a distal end coupled to a power cable bracket such that the distal end of the scope mount and the power cable bracket are positioned to a down-range side of the drawstring with the drawstring in the released configuration, wherein in the released configuration the string carrier is positioned vertically below the scope mount.

11 . A crossbow, comprising:
a drawstring movable between a drawn configuration and a released configuration; a center rail including a bottom portion, a proximal end, and a distal end positioned opposite the proximal end, the center rail at least partially defining a crossbow length and a midpoint plane intersecting a horizontal midpoint of the crossbow; a power stroke distance defined by a length between a distal-most location of the drawstring in the released configuration and a proximal-most location of the drawstring in the drawn configuration; a riser extending horizontally from the distal end and including a first limb and a second limb, the first limb and the second limb flexibly repositionable towards the center rail when the drawstring is in the drawn configuration; a first cam and a second cam respectively attached to the first limb and the second limb via an axle mount, wherein each axle mount is offset from a respective tip of the first limb and the second limb; a trigger extending from the bottom portion of the center rail and configured to control actuation of a drawstring catch; a cocking mechanism slidably coupled within the center rail and actuated via a release located at the proximal end; a rotating member coupled to a flexible tension member, the flexible tension member coupled to the cocking mechanism, the flexible tension member extending above the center rail; a stock coupled to the center rail and including an integral cheek rest, the integral cheek rest positioned at the proximal end; a string carrier including a safety, a rotatable sear, and the drawstring catch, the string carrier slidably engaged within the center rail wherein the safety, the rotatable sear, and at least a portion of the drawstring catch are positioned vertically below the integral cheek rest with the drawstring in the drawn configuration, the safety repositionable between a first position and a second position, the safety including a shoulder and an actuator, the shoulder configured to retain a portion of the rotatable sear in the first position and disengage with the rotatable sear in the second position, the actuator extending from a side of the string carrier, the string carrier defining an arrow capture recess, the arrow capture recess extending towards a proximal end of the string carrier; and a cocking handle configured to rotate the rotating member to retract the flexible tension member; wherein when the drawstr
