A cam assembly for an archery bow is provided. The cam assembly includes a cam body and an anchoring lug. The cam body defines a pivot axis and a groove circumferentially routed at least partially around the pivot axis. The anchoring lug is coupled with the cam body and includes a force sensor. The anchoring lug is offset from the pivot axis and is configured to facilitate attachment of a bow cord thereto. The force sensor is configured to facilitate detection of a tension on the bow cord as a function of a force imparted to the force sensor from the bow cord. An archery bow is also provided.

Stocks for aimable devices are provided. In one aspect, stock has a body mechanically associated with the aimable device and movable to determine an aiming axis of the aimable device, a shoulder mount positioned proximate to one end of the body, a firing grip positioned apart from the shoulder mount along a length of the body; a support leg having a mounting end pivotably mounted to the body between the firing grip and an end of the body opposite from the shoulder mount and having a foot end movable between a first range of positions and a second range of positions and a receiver located between the mounting of the support leg to the body and the firing grip and adapted to releasably hold the support leg in the first range of positions wherein the at least one support leg provides a grippable forestock.

The split cam for a compound archery bow includes a pair of limbs, each limb having a respective loose end and at least two portions. End members are installed on the loose ends, and each end member has a pulley for a bowstring and two attachments for two cables. In between the loose ends, a first cable and a second cable are located on the same side of the bowstring. For each limb, at least one portion of the limb separates the respective pulley from at least one of the attachments for the first cable and the second cable. The portions may be of different resilience. The cam provides for convenient operation of a compound archery bow, increases initial speed of an arrow when shooting, and increases strength and reliability.

In some embodiments, a crossbow crank comprises a housing and a shaft rotatable with respect to the housing. A one-way mechanism is arranged to prevent rotation of the shaft in a first rotational direction, but allow rotation in a second direction. A release mechanism is arranged to disengage the one-way mechanism from the shaft. The release mechanism has a first position and a second position, wherein the release mechanism moves along a length of the shaft between the first position and the second position.

A crossbow may include a bowstring and a string latch that can be moved into a first string latch position that holds the bowstring in a cocked position, a second string latch position that does not hold the bowstring in the cocked position and a third string latch position. To de-cock the crossbow, a de-cock activator may be selectively movable from a first de-cock activator position that prevents the string latch from being moved into the third string latch position into a second de-cock activator position that permits the string latch to be moved into the third string latch position. When the string latch is in the first string latch position and the de-cock activator is in the second de-cock activator position: the string latch may be selectively movable into the third string latch position and then the second string latch position permitting de-cocking of the crossbow.

A crossbow includes a frame and a projectile that moves along a projectile axis when the crossbow is fired. The crossbow includes pulleys and cams to improve performance of the crossbow. Some embodiments include multiple-wind cams.

The invention relates to a bow or prod of a crossbow, said prod having a spring limbs connected with a crosspiece and a working rotatable elements guiding a bowstring and/or cable, and the bowstring and/or the cable, wherein the working rotatable elements guiding the bowstring and/or the cable are located at both ends of the spring limbs, respectively. In one embodiment of the prod, the rear ends of the spring limbs (2) are fastened to both rear ends of the crosspiece (1) by the holders (9) fastened rotatably on the pivots (7a), and the working rotatable elements (3) guiding the bowstring (6) are rotatably fastened to the rear ends of the crosspiece (1) and coaxially with said holders (9), said bowstring (6) is fastened at the fastening point (5) with its for receiving the rear working to the first front end of the crosspiece (1), and similarly with its second end to the second opposite front end of the crosspiece (1). The bowstring (6) runs from its for receiving the rear working through first front working rotatable element (8) guiding the bowstring (6), located on the same side of the prod, and connected coaxially by the pivot (7b) with the holder (9) of the for receiving the rear working of the first spring limb (2), towards the first rear working rotatable element (3) guiding the bowstring (6), located on the same side of the prod, and next towards the second rear working rotatable element (3) guiding the bowstring (6), located on the opposite side of the prod, and further towards the second front working rotatable element (8) guiding the bowstring (6) and connected coaxially with the holder (9) of the front end of the second spring limb (2), and further passing over said second front working rotatable element (8) guiding the bowstring (6), it ends its course at the second front end of the crosspiece (1) with its second end fastened at the fastening point (5). The bowstring (6) runs passes over all the working rotatable elements (3, 8) guiding the bowstring (6).

A projectile launching device includes self-timing without cam lean. The projectile launching device includes a riser, a rail, two energy storing components, (such as two limbs), two cams, a launch string, and least one cable. The ends of the launch string are attached to the two cams. Opposing ends of first and second cables are coupled to the rail. A mid-portion of the first and second cables are slidably engaged with the first and second cams, respectively. Alternatively, a single cable may replace the first and second cables. 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 bow assembly may include bow limbs on opposite sides and a cam rotatably supported to each bow limb. In some embodiments, the cams on each limb may be identical. In other embodiments, each cam may have a stud on each side of the cam that may engage with the bowstring. In yet other embodiments, each cam may have a channel on each side of the cam that may engage with the bowstring.

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.
