An improved crossbow and improved bow and methods for shooting an arrow from such crossbow and how devices. The improved how comprises a pressure sensitive adhesive (PSA) tape on the rail or arrow rest, the surface the arrow slides over when released. The PSA tape provides a smooth surface for the arrow to glide over thereby reducing friction. This is an improved over prior art products such as rail lube or silicone products. The disclosure also comprises an improved method for shooting an arrow with a crossbow comprising PSA tape on the rail or arrow rest.

A firing system for a crossbow having an arrow rest extending along an arrow rest axis, the firing system having a right limb and a left limb, the right limb being pivotable about a right limb axis and the left limb being pivotable about a left limb axis, the firing system further including a right cam and a left cam, the right cam having a right bow string groove and being rotatable about a right cam axis, the left cam having a left bow string groove and being rotatable about a left cam axis, the firing system having a bow string extending between the right and left cams and extending within the right and left bow string grooves, the bow string positionable between an un-cocked condition and a cocked or full draw condition wherein movement of the bow string from the un-cocked condition toward the cocked condition moves the right and left cams toward each other and pivots the right and left limbs about the right and left limbs axes respectively, the firing system further including a power assembly having a power cable and a spring assembly, the power cable having a forward end operably joined to the right and left limbs and a rear end operably joined to the spring assembly, the spring assembly having a power spring extending along a power spring axis between a first spring end and a second spring end and having a central spring opening, the power spring being below the arrow rest, the power cable extending through the central spring opening from the first spring end toward the second spring end, the rear end of the power cable being operably joined relative to the second spring end of the power spring, moving the bow string from the un-cocked condition to the cocked condition causing the right and left limbs to the pull forward end of the power cable forwardly wherein the operable engagement with the second spring end compressing the power spring by pulling the second spring end toward the first spring end to produce the shooting force to propel the archery arrow.

A trigger-traverse crossbow. The crossbow has a trigger latch block slidingly connected to the flight track. The trigger latch block is configured to engage and retain the bowstring. A cocking mechanism is configured to draw the trigger latch block with the bowstring from an initial position near a forward end of the flight track to a cocked position. A one-way retention mechanism is configured to immobilize the trigger latch block against linear movement in a forward direction along the flight track. A trigger-traverse mechanism is configured to slide the trigger latch block in a forward direction to its initial position after the bowstring is released. In one embodiment, the cocking mechanism includes a cocking lever pivotally connected to the crossbow body along with one pair or two pairs of cocking hooks that move in response to the rotation of the cocking lever.

A crossbow includes a frame, where the frame is provided with an arrow track for placing an arrow; the crossbow includes at least one limb; the limb includes a fixed end and a movable end; the movable end is moved toward the fixed end under pressure, such that two sections bent in opposite directions are formed on the limb to make the limb wave-shaped; the movable end is moved in a reverse direction to make the limb restored; and a primary string of the crossbow is directly or indirectly connected to the movable end of the limb. The limb of the crossbow can generate large elastic potential energy and can reduce the kinetic energy consumed by translation, and avoids the problem of different strokes between multiple limbs. The crossbow prevents the winding wheels from translating to consume the kinetic energy, such that the arrow can gain sufficient kinetic energy.

A bow assembly includes a bow body assembly that pulls a string to shoot an arrow by a force generated by a rebound of an elastic body, where the bow body assembly is pivotally connected to a winding assembly for winding the string; and the winding assembly slides from a first position of the bow body assembly to a second position of the bow body assembly through a sliding assembly. The bow assembly involves manual winding, but the manual winding process will not exert any force on a limb, and a winding wheel can be moved by driving the sliding assembly by pedaling. In a shooting phase, the winding assembly is fixed relative to a bow body. In addition, the energy efficiency enhancer enables the winding wheel to continue to rotate after a limited number of revolutions. Further, as the winding wheel will not stop abruptly, noise is reduced.

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.

In some embodiments, an archery bow comprises a frame, a first limb assembly supporting a first rotatable member and a second limb assembly supporting a second rotatable member. The first rotatable member comprises a cam. A bowstring extends between the first rotatable member and the second rotatable member. A power cable is in communication with the cam. The first limb assembly has a width and a length, wherein the width is at least 26% of the length. In some embodiments, the width is at least 28% of the length.

A pneumatic actuator having therein a venting element and a porous element, compression and elongation of the actuator creating an air flow in the venting element and porous element to output lubricant as a mist toward a sliding interface of the actuator. A bow using the actuator and a bow having a double string preventing sideward movement when launching an arrow. A compound bow having limbs with multiple rotatable elements and an actuator rotating such elements to launch an arrow.

A crossbow de-cock mechanism may include a de-cock activator that is selectively movable from a first de-cock activator position that prevents de-cocking of a crossbow into a second de-cock activator position that permits de-cocking of the crossbow.

A projectile launching device includes self-timing without cam lean. The projectile launching device preferably includes a rail, a riser, two energy storing components, (such as two limbs), two cams, a launch string, and at least two cables. The ends of the launch string are attached to the two cams. Opposing ends of first and second cables are coupled to the first and second cams. A mid-segment of the first and second cables are slidably engaged with the first and second cable pulleys, respectively. The two cams are preferably built as mirror images of each other at a centerline of the rail. The two cams include a launch string track, having identical, but mirrored, upper and lower cable tracks. A stop is formed on each cam to prevent the cam from being able to rotate in a direction opposite the direction of drawing, when the bow is at rest.
