Abstract

A multi-stroke lever action crossbow has two sets of cocking hooks. The first cocking hooks are disposed on cocking links slidingly coupled to a crossbow body. The second cocking hooks are retractable. The second cocking hooks are disposed on a cocking arm, which is pivotally attached to a cocking lever. A retractable handover latch operatively engages the cocking arm. During the first stroke of the cocking lever, the first cocking hooks draw the bowstring past the handover latch, where the bowstring is retained in a partially drawn position. During the second stroke of the cocking lever, the second cocking hooks draw the bowstring past a trigger latch, where the bowstring is retained in a fully drawn position. When the cocking lever returns to its initial closed position, the second cocking hooks and the handover latch are retracted into the crossbow body.

First claim

I claim:

1. A crossbow comprising:
a body having a flight rail;
a prod affixed to the body of the crossbow;
a bowstring stretched between a first end and a second end of the prod;
a cocking lever pivotally connected to the body;
a handover latch at least partially disposed within a cavity in the body, wherein the handover latch is configured to selectively move between a retracted position in which the handover latch is disposed below the flight rail and an extended position in which a latch surface of the handover latch protrudes above the flight rail;
a first hook slidingly connected to the body, wherein the first hook is configured to slide along the body in response to rotation of the cocking lever in a first rotation cycle to draw the bowstring from a resting position to a partially drawn position in which the bowstring engages the latch surface of the handover latch;
a second hook slidingly connected to the body, wherein the second hook is configured to selectively move between a retracted position in which the second hook is positioned below the flight rail and an extended position in which the second hook protrudes above the flight rail, and wherein the second hook is configured to slide along the body in the extended position in response to rotation of the cocking lever in a second rotation cycle to draw the bowstring from the partially drawn position to a fully drawn position in which the bowstring engages a trigger latch.

2. The crossbow of claim 1 , wherein rotation of the cocking lever moves the second hook between the retracted position and the extended position, and wherein rotation of the cocking lever moves the handover latch between the retracted position and the extended position.

3. The crossbow of claim 1 , wherein the second hook is configured to remain in the extended position to retain the bowstring when the bowstring exerts a force on a rearward surface of the second hook in the extended position; wherein the handover latch is configured to remain in the extended position to retain the bowstring when the bowstring exerts a force on the latch surface of the handover latch in the extended position.

4. The crossbow of claim 3 , wherein the second hook is configured to move from the extended position into the retracted position when the bowstring exerts a force on a forward surface of the second hook, and wherein the handover latch is configured to move from the extended position into the retracted position when the bowstring exerts a force on a forward surface of the handover latch.

5. The crossbow of claim 1 , wherein the second hook is also configured to slide along the body in response to rotation of the cocking lever in the first rotation cycle; and wherein the first hook is also configured to slide along the body in response to rotation of the cocking lever in the second rotation cycle.

6. The crossbow of claim 1 , wherein the body further includes a handover latch guide slot in each of its side surfaces, and wherein the handover latch includes a pin extending through the handover latch guide slot.

7. The crossbow of claim 1 , further comprising a cocking link slidingly connected to the body, wherein the first hook is disposed at a forward end of the cocking link.

8. The crossbow of claim 7 , further including a forward stop extending from a side surface of the body, wherein the forward stop is configured to limit the forward movement of the cocking link as it slides along the body.

9. The crossbow of claim 7 , wherein the body includes a longitudinal groove in a side surface, and wherein the cocking link includes one or more sliding pins that are slidingly engaged with the longitudinal groove.

10. The crossbow of claim 7 , further comprising a cocking arm pivotally connected to the cocking lever, wherein the cocking arm is operatively connected to the cocking link, wherein the second hook is disposed at a forward end of the cocking arm.

11. The crossbow of claim 10 , wherein the handover latch is biased in an upward direction, and wherein the cocking arm limits the upward movement of a rearward end of the handover latch to retain the handover latch in the retracted position when the cocking lever is in a fully closed position.

12. The crossbow of claim 10 , wherein the cocking link further includes a cocking arm guide slot, and wherein the cocking arm includes a pin extending through the cocking arm guide slot.

13. The crossbow of claim 1 , further comprising a retractable sling configured to be extended to form a carrying handle for the crossbow.

14. A crossbow comprising:
a body having a flight rail;
a prod affixed to the body of the crossbow;
a bowstring stretched between a first end and a second end of the prod;
a cocking lever pivotally connected to the body;
a handover latch at least partially disposed within a cavity in the body, wherein the handover latch is configured to selectively move between a retracted position in which the handover latch is disposed below the flight rail and an extended position in which a latch surface of the handover latch protrudes above the flight rail;
a pair of cocking links with a first hook disposed at a forward end of each cocking link, wherein each cocking link is connected to a side of the body, wherein the cocking links are configured to slide along each side of the body to engage the bowstring with the first hooks in response to rotation of the cocking lever in a first rotation cycle to draw the bowstring from a resting position to a partially drawn position in which the bowstring engages the latch surface of the handover latch;
a pair of cocking arms with a second hook disposed at a forward end of each cocking arm, wherein each cocking arm is pivotally connected to the cocking lever and operatively connected to one of the cocking links, wherein the second hooks are configured to selectively move between a retracted position in which the second hooks are positioned below the flight rail and an extended position in which the second hooks protrude above the flight rail, and wherein the cocking arms are configured to slide along each side of the body to engage the bowstring with the second hooks in the extended position in response to rotation of the cocking lever in a second rotation cycle to draw the bowstring from the partially drawn position to a fully drawn position in which the bowstring engages a trigger latch.

15. The crossbow of claim 14 , wherein rotation of the cocking lever moves the second hooks between the retracted position and the extended position; and wherein rotation of the cocking lever moves the handover latch between the retracted position and the extended position.

16. The crossbow of claim 14 , wherein the second hooks are configured to remain in the extended position to retain the bowstring when the bowstring exerts a force on a rearward surface of each of the second hooks, wherein the handover latch is configured to remain in the extended position to retain the bowstring when the bowstring exerts a force on the latch surface of the handover latch.

17. The crossbow of claim 16 , wherein the second hooks are configured to move from the extended position into the retracted position when the bowstring exerts a force on a forward surface of each of the second hooks; and wherein the handover latch is configured to move from the extended position into the retracted position when the bowstring exerts a force on a forward surface of the handover latch.

18. The crossbow of claim 14 , wherein the handover latch is biased in an upward direction, and wherein the cocking arms
