    • An adjustable bow sight assembly (10) includes a mounting plate (16) extending between first and second ends (18,20). End caps (24,26) include longitudinal channels (28) for receiving the ends (18,20) in sliding engagement therein. Each of the end caps (24,26) also include a transverse aperture (44) therethrough to receive a sight bar (40,42) slidably therein. An adjustment mechanism (70) including a rack gear (80) on the end cap (24) and a spur gear (82) mounted to the plate (16) allow for selective adjustment of the end cap (24) in a vertical direction while maintaining the sight bar (40) in a fixed horizontal direction. A lever (72) is fixed to the spur gear (82) and pivotally connected to the plate (16) for rotating the gear (82) and translating the end cap (24) in the vertical direction.
    • 可调式弓形瞄准器组件(10)包括在第一和第二端(18,20)之间延伸的安装板(16)。 端盖(24,26)包括用于接收其中滑动接合的端部(18,20)的纵向通道(28)。 每个端盖(24,26)还包括穿过其中可滑动地接纳视杆(40,42)的横向孔(44)。 包括在端帽(24)上的齿条(80)和安装到板(16)的正齿轮(82)的调节机构(70)允许在垂直方向上选择性地调节端帽(24),同时 将瞄准杆(40)保持在固定的水平方向上。 杠杆(72)固定在正齿轮(82)上并枢转地连接到板(16)上,用于使齿轮(82)旋转并在垂直方向平移端帽(24)。
