The second bottom helical path 464 may be a cylindrical helix or a spiral helix. In some non-limiting embodiments the second bottom power cord channel 462 is a mirror image of the second top power cord channel 452.

With continued reference to the crossbow shown in FIG. 2, an elongated bowstring may have a first end 34a and a second end 34b opposite the first end 34a. In some embodiments, the first end 34a may be operatively engaged with the first cam 38. In some embodiments, the second end 34b may be operatively engaged with the second cam 38. The bowstring may be movable between a cocked position and an uncocked position as detailed herebelow.

With continued reference to the crossbow shown in FIG. 2, a first bowstring guide 282 may be engaged with the first barrel side 16c. The first bowstring guide 282 may be adapted to push the bowstring 34 toward the second barrel side 16d during at least part of an operation during which the bowstring 34 is moved between a cocked position and an uncocked position.

With continued reference to the crossbow shown in FIG. 2, a second bowstring guide 282 may be engaged with the second barrel side 16d. The second bowstring guide 282 may be adapted to push the bowstring 34 toward the first barrel side 16c during at least part of an operation during which the bowstring 34 is moved between a cocked position and an uncocked position.

An operation during which the bowstring 34 is moved between a cocked position and an uncocked position may refer to either: a cocking operation, or a decocking operation. During a cocking operation, the bowstring 34 is moved from an uncocked position to a cocked position. FIGS. 3, 4, 5, and 6, in that order, show the progress of a cocking operation as a user moves a bowstring from an uncocked position toward the cocked position shown in FIG. 7. During a decocking operation, the bowstring 34 is moved from a cocked position to an uncocked position. FIGS. 8, 9, 10, and 11, in that order, show the progress of a decocking operation as a user moves a bowstring from the cocked position shown in FIG. 7 to an uncocked position.

In some embodiments, a crossbow may comprise one or more bowstring guides 282, 284. The bowstring guide 282, 284, may be a pin, wheel, pulley, or other surface adapted to guide the path of a bowstring during a cocking operation or a decocking operation. In the non-limiting embodiment shown in FIGS. 2-11, there is a first bowstring guide 282 on a first barrel side 16c and a second bowstring guide 284 on a second barrel side 16d. The bowstring in the uncocked position extends between two offset cams 38. As shown in FIG. 3, as the bowstring is gradually cocked, it is pulled back and forms a broad generally V-shaped form. As shown in FIG. 4, as the bowstring is further cocked, it is pulled back and comes into contact with the bowstring guides 282, 284 which change the from the cocked bowstring 34 from a simple V-shape to one which is narrows at the guides to more closely conform to the barrel 16. In these embodiments the bowstring guides 282, 284 help to prevent the bowstring from striking, interfering with, or contacting components with which an unguided bowstring would strike, interfere, or contact. In FIGS. 2-11, the power cord and guide elements for the power cords are separated from the path of the bowstring by the bowstring guides 282, 284.

It should be noted that in some embodiments, the bowstring guides 282, 284 may only contact the bowstring 34 during a portion of the cocking operation or decocking operation. As shown in FIG. 3 the bowstring 34 has not yet contacted the guides 282, 284. As shown in FIG. 4 the bowstring 34 is in contact with the guides 282, 284. As shown in FIG. 6 the bowstring 34 is in no longer contact with the guides 282, 284: the cams have pulled together sufficiently that the top of the V-shaped form defined by the bowstring is narrow enough that the bowstring 34 is in no longer contact with the guides 282, 284. As shown in FIG. 7 the bowstring 34 is in no longer contact with the guides 282, 284. In the images showing the decocking of the bowstring 34, FIGS. 8-11 it can be seen that the bowstring 34 contacts the guides as it moves to uncocked position but then again moves out of contact therewith. It should be understood that a firing operation is a form of decocking operation.

In the non-limiting embodiments shown the bowstring guides are pulleys and each defining an operational plane, the operational planes of the guides are coincident with one another and are coincident with the first cam plane and the second cam plane.

Numerous embodiments have been described, hereinabove. It will be apparent to those skilled in the art that the above methods and apparatuses may incorporate changes and modifications without departing from the general scope of the present subject matter. It is intended to include all such modifications and alterations in so far as they come within the scope of the appended claims or the equivalents thereof.
