    • A crossbow includes a trigger mechanism providing positive setting or cocking and release of a drawn bowstring. As the bowstring is drawn, it is pulled rearwardly into a trigger assembly slot to momentarily rearwardly deflect and ride over a spring-urged string catch member. Deflection of the catch member in turn urges displacement of a safety element into locking engagement with a pivotal sear. A nose on the locked sear normally abuts the catch member to preclude its release of a bowstring cocked therebehind. Following manual displacement of the safety to an off position, squeezing of a trigger pivotally moves the sear nose clear of the catch member to permit the cocked bowstring to forwardly deflect and pass over the catch member as the bowstring leaves the trigger assembly and propels an arrow engaged thereby.
    • 弩包括一个触发机构,提供正向设置或起动和释放拉伸弓弦。 当弓弦被拉动时,它被向后拉动到触发器组件槽中,以瞬时向后偏转并且骑过弹簧推动的线扣构件。 卡扣构件的偏转又推动安全元件与枢转掣子的锁定接合的位移。 被锁定的通道上的鼻子通常与捕捉物体抵接,以防止其释放出弓弦。 在将安全性手动移动到关闭位置之后,挤压触发器将扣钉头枢转地移动,使抓钩构件远离捕获构件,以允许当弓弦离开触发器组件并且推动箭头时,被锁定的弓弦杆向前偏转并越过捕捉构件 从而。

    • An improved compound bow having a rigid lightweight, high strength central portion which connects the opposed inner ends of the bow limbs and includes spaced apart, centrally offset tubular risers. The riser offsetting provides a sight window which extends over the entire space intermediate the limbs. The tubular risers are preferably made of lightweight extruded material to impart strength while maintaining reduced weight and fabrication costs. The riser is affixed to the bow limbs through limb boots and the riser may carry a laterally extending suppport platform. The platform is constructed to rigidly support either a right or left handed grip, a draw cable guard and if desired an arrow rest and a target sight. The components may be of modular construction to permit the compound bow to be readily assembled into a length suitable for a right or left handed individual archer.
    • 一种改进的复合弓,其具有刚性轻质的高强度中心部分,其连接弓形肢的相对的内端并且包括间隔开的中心偏移的管状立管。 提升器偏移提供了在四肢中间的整个空间上延伸的视窗。 管状立管优选地由轻质挤压材料制成,以赋予强度,同时保持减轻重量和制造成本。 提升管通过肢体靴固定在弓形肢上,提升管可以承载横向延伸的支撑平台。 平台被构造成刚性地支撑右手或左手的手柄,牵引电缆护罩,如果需要的话,可以使用箭头和目标瞄准器。 组件可以是模块化构造,以允许复合弓被容易地组装成适合于右手或左手的个人弓箭手的长度。

    • A compound bow is provided with a hanger assembly for attaching wheels or cams and power cables to both bow limb tips and includes a pair of hanger members removably engageable with the distal portions of two split limb portions on each bow limb without the need for separate fastener members. A pair of side walls on each hanger member provide four laterally spaced apart points supporting a transverse axle adjacent each limb tip on the belly side of the limb. The axles in turn support the wheels or cams and respective ends of the power cables with the tension applied by the strung cables providing the sole force retaining each hanger assembly in place.

    • A compound bow includes a single, integrated cam assembly supported by the bow handle and having separate, adjacent cam elements receiving string cable segments and power cable segments from the bow limb tips. All the cam elements are fixedly disposed relative one another and are mounted for arcuate displacement as a unit. The plurality of cam elements and attendant bow structure are disposed in a manner resulting in shortened limb tip travel for a given bowstring displacement. The draw length of the bow is readily altered without dismantling the bow cable components and without any tools by removing and relocating end portions of the power cables in selected ones of a plurality of retainer pockets in the cable assembly and further draw length modification is obtainable, without changing the bow peak draw weight, through interchangable power cable cams.
