摘要： An arrow rest for archery bows which includes a mounting bracket which may be fixed to the bow. The mounting bracket may be of an extended rearward length, such that the arrow rest may be employed with arrows having a shorter length. The mounting bracket supports a pivot cylinder for rotation therein. Mounted about the pivot cylinder is a support collar which may be adjusted circumferentially and longitudinally of the cylinder. The collar mounts a pair of arrow supports which are elongated and extend outward toward free ends. Adjustment means are provided to vary the distance between the free ends for different arrow types. A coil spring is located within the cylinder and is fixed to one end thereof. The mechanism for fixing the spring to the cylinder may also function as a limit on the rotation of the cylinder. An adjustment member is releasably fixed to the mounting bracket and extends into the cylinder. The second end of the coil spring is fixed to the adjustment member, such that relative rotation between the adjustment member and the cylinder will place different torsional forces upon the coil spring which are transferred to the cylinder. This allows adjustment of the force required to deflect the arrow support members.

摘要翻译： 弓箭的箭头放置，包括可以固定在弓上的安装支架。 安装支架可以具有延伸的后向长度，使得箭头可以与具有较短长度的箭头一起使用。 安装支架支撑用于在其中旋转的枢轴筒。 围绕枢转圆筒安装的是可以圆柱体和圆柱体的纵向调节的支撑轴环。 套环安装一对伸长的向箭头的箭头支撑，向着自由端向外延伸。 提供调节装置以改变不同箭头类型的自由端之间的距离。 螺旋弹簧位于气缸内并固定在其一端。 用于将弹簧固定到气缸的机构也可以用作气缸旋转的限制。 调节构件可释放地固定到安装支架并延伸到气缸中。 螺旋弹簧的第二端固定到调节构件，使得调节构件和气缸之间的相对旋转将对传递到气缸的螺旋弹簧产生不同的扭转力。 这允许调节使箭头支撑构件偏转所需的力。
