摘要:
An arrow rest that drops away or otherwise moves away from a discharging shaft of an arrow or another projectile. An arrow holder is operable between two support positions and a launch position. A support force is used to keep or maintain the arrow holder in the support position. A movement force can be transferred to the arrow holder for overcoming the support force and moving the arrow rest into a launch position, away from a discharging arrow shaft and the corresponding fletching.

An arrow nock system for holding an arrow and permitting true release from a bow wherein an arrow nock is positioned on an end of an arrow shaft and is magnetically engageable with a ball nock having an at least partially spherical outer surface attached to a bowstring.

A mechanical release or trigger device including a body. A trigger forming a shaft is movably mounted with respect to the body. At least one caliper is mounted with respect to the body and operatively connected to the trigger. The caliper is movable between a closed position and an open position, in response to a movement of the trigger. A sleeve is rotatably mounted with respect to the trigger and movable along an axis of the shaft. At least one stop element can be mounted with respect to the shaft at a first end portion of the sleeve or a second end portion of the sleeve, to limit axial movement of the sleeve. In one embodiment wherein the sleeve is asymmetric, and operatively connected to activate another mechanism such as a safety or firing system, a bias element can be operatively connected to the sleeve to bias the sleeve towards a first rotational position.
摘要:
An arrow nock and release system for holding and then releasing an arrow from a bow wherein a ball nock is positioned on an end of an arrow shaft, the ball nock having an at least partially spherical outer surface divided with a string groove. An arrow release is engageable with the ball nock and includes a jaw with an engagement surface corresponding with the outer surface of the ball nock, the jaw releaseably engageable with the ball nock.

A moveable arrow rest having a support element that moves between an unloaded position and a loaded position, with respect to an archery bow. The archery bow has a bow cable. A cam element is fixed with respect to the bow cable. A lever is fixed with respect to the support element. A cam surface of the cam element contacts the lever and translates movement of the bow cable into movement of the support element.

A device for reducing vibration and shock in an archery bow includes a base and an integral body formed of a flexible material. The body includes a non-uniform cross-section as the body extends away from the base and terminates in a peripheral mass positioned on a distal portion of the body opposite the base. As a result of such an arrangement, including the alternative of positioning two devices in axial alignment on an archery bow limb, vibration and shock following discharge of an arrow are greatly reduced in the archery bow.

An archery vane having a first side with a first surface and an opposing second side with a second surface, the second surface having a roughness greater than the roughness of the first surface. A projection is attached to the first surface. The archery vanes generate rotation of the arrow shaft about its spin axis to provide increased stability of the arrow shaft and improved flight accuracy of the arrow. Arrows having such archery vanes are easily and efficiently manufactured due to the position of the archery vanes on the arrow shaft generally parallel to the spin axis.

An apparatus for adjustably mounting an arrow rest with respect to a mounting bracket that attaches to an archery bow. A pivot shaft has a mounting end portion which accepts the arrow rest. The pivot shaft also has an externally threaded end portion which is opposite the mounting end portion. A bearing housing is rotatably mounted with respect to the mounting bracket. The bearing housing has a throughbore and a cavity within which the pivot shaft is rotatably mounted. A tension knob is rotatably mounted within the cavity of the bearing housing. The tension knob also has a throughbore within which the pivot shaft is mounted. A spring is mounted within the cavity of the bearing housing. One end portion of the spring is fixed with respect to the pivot shaft and the opposite end portion of the spring is fixed with respect to the tension knob. A windage knob also has a throughbore within which the pivot shaft extends. At least a portion of the throughbore of the windage knob is internally threaded. Internal threads of the throughbore of the windage knob engage with the external threads of the end portion of the pivot shaft. The arrow rest of this invention can accomplish independent and isolated adjustment of one of the following three parameters, without affecting the setting of the other two of the following three parameters, horizontal movement of the pivot shaft; rotational movement of the pivot shaft; and tension adjustment of the spring.
摘要:
An archery broadhead having a ferrule body with longitudinal grooves that accept a plurality of fixed and/or pivotal blades. At least a port ion of the ferrule body has a multiplicity of irregularities that form an irregular skin surface having a surface roughness. The irregularities enhance aerodynamic flight characteristics of the broadhead and also reduce frictional drag as the broadhead penetrates a target. The irregularities can be formed by a directional, non-directional or multi-directional set of repeating dimples, grooves, lands, stippling and/or any other suitable structure that forms a pattern, uniform or non-uniform.

A grounding kit for a transmission line cable having a portion of its outer jacket removed to reveal an exposed section of its conductor is set forth. The grounding kit includes a clip, a bail and a housing. The clip has a fulcrum portion and means for connecting the clip to a ground wire. The clip encompasses a part of the exposed section of the conductor. The bail includes a mounting element pivotably mounted on the fulcrum portion of the clip to permit rotation of the bail between an open position and a closed position. The handle contacts the clip and forces the clip into clamping engagement with the exposed section of the conductor in response to the bail being rotated to the closed position. The hollow housing has an opening at both ends and an exit port. The housing encompasses and seals the clip, the bail and the exposed conductor. The transmission line cable on either side of the exposed section exits the hollow housing through its end openings while the grounding wire exits the hollow housing through the exit port.
