10 . The crossbow of claim 8 , wherein the cocking mechanism further includes a first pulley, tensioner, and a second pulley, wherein the cord is routed from the spool to the first pulley, from the first pulley to the tensioner, from the tensioner to the second pulley, and from the second pulley to the trigger box.
11 . The crossbow of claim 10 , wherein, in operation, the second pulley vertically alters a position of the cord.
12 . The crossbow of claim 10 , wherein the tensioner is configured to adjust a tension of the cord.
13 . The crossbow of claim 8 , further comprising:
a frame coupled to the second plate, the frame defining a channel;
wherein a first portion of the cord extends within the channel; and
wherein a second portion of the cord extends within the slot of the second plate.
14 . The crossbow of claim 1 , wherein the trigger box includes a string catch configured to selectively engage with the draw string to selectively retain the draw string in the drawn position, and wherein the trigger box includes a magnet configured to magnetically interact with the string catch to inhibit rotation of the string catch.
15 . A crossbow, comprising:
a first plate including a slot;
a second plate including a slot, the second plate coupled to the first plate and extending substantially parallel to the first plate, the second plate spaced apart from the first plate to define an opening;
an upper flexible limb coupled with the first plate;
a lower flexible limb coupled with the second plate;
a draw string operatively engaged with the upper flexible limb and the lower flexible limb, the draw string located within the opening and configured to move from a released position to a drawn position; and
a trigger box slidably coupled with the first plate and the second plate and including a first protrusion configured to be received within the slot of the first plate and a second protrusion configured to be received within the slot of the second plate, the trigger box configured to selectively engage with the draw string to move the draw string between the released position and the drawn position.
16 . The crossbow of claim 15 , wherein the trigger box is positioned between the first plate and the second plate and is configured to slide along a length of the slot of the first plate and a length of the slot of the second plate.
17 . The crossbow of claim 15 , wherein the first protrusion and the second protrusion include friction-reducing elements.
18 . A crossbow, comprising:
a frame;
a first plate including a slot;
a second plate including a slot, the second plate coupled to the frame and the first plate and extending substantially parallel to the first plate, the second plate spaced apart from the first plate to define an opening;
an upper flexible limb coupled with the first plate;
a lower flexible limb coupled with the second plate;
a draw string operatively engaged with the upper flexible limb and the lower flexible limb, the draw string located within the opening and configured to move from a released position to a drawn position;
a trigger box slidably coupled with the first plate the second plate within the slot of the first plate and the slot of the second plate, the trigger box configured to selectively engage with the draw string to move the draw string between the released position and the drawn position; and
a cocking mechanism coupled with the trigger box and configured to cause the trigger box to move the draw string between the released position and the drawn position, the cocking mechanism coupled with the first plate.
19 . The crossbow of claim 18 , further comprising:
a cocking mechanism including a spool; and
a tether coupled with a second end of the trigger box and the cocking mechanism, wherein the cocking mechanism is configured to wind the tether about the spool to move the trigger box toward a rear end of the crossbow; and
