An axle assembly for a bow. The assembly includes spacers that can be used to adjust the position of a rotatable member axially along an axle that supports the rotatable member. The spacers can each have a snap-on configuration and can be installed and removed from the axle using an installation tool. The rotatable member can be mounted on the axle by a bearing assembly, and the axle assembly can include features for preventing thrust load from being applied to the bearing assembly.

A transducer assembly includes a mounting base, a collar, a magnet, and a Hall effect sensor. The collar defines a bore. One of the magnet and the Hall effect sensor is disposed within the bore and attached to the mounting base. The other of the magnet and the Hall effect sensor is attached to the collar. The Hall effect sensor is spaced from the magnet and is configured to detect movement of at least a portion of the collar relative to the mounting base.

A bow including: a frame having a predetermined length; a first pulley and a second pulley arranged on a first position and second position of the frame respectively; a first small diameter cam and a first large diameter cam rotated interlocked with the first pulley; a second small diameter cam and a second large diameter cam rotated interlocked with the second pulley; a string fixed to the first pulley and the second pulley, the first pulley and the second pulley being rotated when the string is pulled; a first cable and a second cable arranged in a linear shape between the first (second) small diameter cam and the second (first) large diameter cam, the first cable and the second cable being elastically deformed by being wound around the second large diameter cam or the first large diameter cam when the string is pulled.

A crossbow including a center rail including a rail body and a riser, a first flexible limb coupled to the riser, a second flexible limb coupled to the riser, and a first cam mounted to the first flexible limb and rotatable around a first cam axis, and including a first draw string journal defining a first draw string plane of rotation perpendicular to the first cam axis, and a first power cable take-up journal extending in a direction perpendicular to the first draw string plane of rotation. The crossbow including a second cam mounted to the second flexible limb and rotatable around a second cam axis. The second cam including a second draw string journal defining a second draw string plane of rotation perpendicular to the second cam axis, and a second power cable take-up journal extending in a direction perpendicular to the second draw string plane of rotation.

A bow (e.g., compound bow, cross bow, etc.) that includes a cable splitter. The cable splitter is easy to install in that it does not require access to the yoke ends of the bow string. The cable splitter is self-anchoring to the cable. In addition, the cable splitter eliminates the need for a separate saddle and separate section of cable. The cable splitter also allows for tuning for cam lean by adding or removing twist in the yoke ends.

A transducer assembly includes a ring wall, a first arm, a second arm, a magnet, and a Hall effect sensor. The ring wall defines a bore. The first and second arms are disposed within the bore and include first and second proximal and distal ends, respectively. The first and second proximal ends are coupled to and extend from first and second interior locations of the ring wall, respectively. The second interior location is spaced from the first interior location. The magnet is disposed within the bore and is fixedly coupled to the first arm. The Hall effect sensor is disposed within the bore and is fixedly coupled to the second arm. The Hall effect sensor is spaced from the magnet and is configured to detect movement of the magnet resulting from compression of the ring wall. Methods are also provided.

A crossbow may include a main beam, a riser with a U-shaped opening, a pair of bow limbs and a bowstring. The riser may have limb attachment surfaces that are separated such that a minimum distance between them is at least as wide as a user's foot but not greater than about 5 inches. The riser may have a U-shaped opening that is designed to receive a user's foot.

A reduced length crossbow with a trigger located near a midpoint of the crossbow and a small included angle of the draw string when in the drawing configuration that creates a space between the draw string and the user's face. The included angle of the draw string when in the drawing configuration may be less than about 25 degrees. The trigger is typically located proximate the midpoint within about 10% of the overall length of the crossbow.

A bow-type throwing tool includes a central body, a nocking string for an arrow, and elastic energy storage mechanism operated by the traction of the string. The elastic energy storage mechanism includes: two opposed primary levers connected with hinging to the central body, the nocking string being constrained by its opposite ends to opposite free ends of the primary levers; two opposed axial action thrust accumulators, defined on the central body; a loading element of the axial action thrust accumulators configured to induce a compression in the thrust accumulators following a traction of the nocking string.
