摘要： An archery bow assembly is provided including an open sided spacer which is mountable to an axle on an archery bow and removable therefrom without removing the axle entirely or partially from a limb of the archery bow. The spacer can mount on the axle adjacent a cam rotatable on the axle, and can include an outer perimeter and an axle aperture. A recess can extend inward from the outer perimeter to the axle aperture so that the axle aperture and recess form a continuous opening. The spacer can be of a C-shape or E-shape so that it can be frictionally pressed onto the axle and removed therefrom without removing the axle from the limb arms adjacent the cam. Related methods also are provided.

摘要： An archery training aid is provided including a body and a finger rest extending outward at an angle from a base. The finger rest can include a finger rest surface configured to engage one or more fingers of a hand. The base can be configured to be placed in engagement with a first lateral grip surface of a bow grip so that the finger rest surface is disposed at a first angle between 25° to 65°, inclusive, or between 30° and 50°, inclusive, relative to the first lateral grip surface. A related method of use is provided to impair or prevent bow torque imparted by an archer's hand on a bow.

摘要： A mechanical broadhead, which has blades movable from a retracted mode to a deployed mode, is provided with ball and socket members that hold the blades in the retracted mode, and selectively release the blades to the deployed mode. The ball and socket members, which can be on the blades and/or on a retainer element, can be snapped together to provide an audible snap confirming locking of the blades in the retracted mode. The mechanical broadhead can include first and second ferrule portions removably joined with one another. The second ferrule portion can acquire a blocking mode to block a removal opening of a ferrule slot defined in the first ferrule portion so that blade cannot be removed from respective ferrule slots. The second ferrule portion can achieve a removal mode so that the blades can be removed from the slots.

摘要： An aiming device is provided including an illumination device and an optical element wherein the illumination device projects a primary dot and at least one secondary alignment dot distal from the primary dot to aid a user in obtaining a view of the primary dot when the aiming device is in an aligned mode, the primary dot is visible within a field of view of the user, but the secondary alignment dot is not visible. When the aiming device is in a misaligned mode, the secondary alignment dot is visible to the user, but the primary dot is not. The secondary alignment dot provides instruction to the user to realign the aiming device relative to the field of view of the user so that the aiming device transitions to the aligned mode. A related method of operation is provided.

摘要： A grip for a weapon is provided and can include a user engagement area including a first surface on the weapon, a first layer including an aerogel, the first layer disposed adjacent the first surface, and a first engagement member disposed over the first layer in the user engagement area. The first engagement member includes an exterior surface that engages an appendage of a user when the user holds the weapon. The first layer including the aerogel insulates the first engagement member so that thermal energy transfer between the user and the weapon is impaired. The weapon can be an archery bow, a firearm or any other weapon including a grip or portion that is engaged by an appendage of a user.

摘要： An archery practice field tip and related method of use is provided, where the field tip has a first shape that is structurally different from a second shape of an actual hunting broadhead, but where the tip mimics the aerodynamics and flight characteristics of the hunting broadhead. The practice tip can be void of sharpened cutting edges, and can include a head on drag promoting element and/or a crosswind drag promoting element, either of which can be scoops, flanges, fins, holes and the like. The tip can have a head on aerodynamic drag that is within 40%, within 25%, within 10% and/or within 5% of the first head on aerodynamic drag of the hunting broadhead. The practice tip can have a crosswind aerodynamic drag that is within 40%, within 25%, within 10% and/or within 5% of the crosswind aerodynamic drag of the hunting broadhead.

摘要： A broadhead is provided including a ferrule defining a slot. A blade is movable within the slot from a retracted mode to a deployed mode. The blade includes a lever arm projecting from the slot on a ferrule side opposite a cutting edge. The blade can include an interference projection that engages an exterior of the ferrule to retain the blade in the retracted mode. The blade can include a retention arm that selectively engages the ferrule to hold the blade in the retracted mode or the deployed mode. The broadhead can include a collar selectively disposed in a collar recess of the blade to hold the blade in the retracted mode. The broadhead can include a plunger and/or pivotable pawl that selectively engage the blade to hold it in a desired mode.

摘要： An archery bow is provided including a cable guard and/or cable guide that can flex to selectively move a cable relative to a plane in which a bowstring of the bow travels to minimize cam lean, limb twist, and/or cable wear. The cable guard and/or guide can move toward the bowstring plane as the bowstring is drawn, and away from the bowstring plane, out of the way of the bowstring and any attached arrow, after the bowstring is released. The cable guard can define a bore, for example, an elongated bore, extending through it along an axis that is generally parallel to the bowstring when the bowstring is undrawn. The cable guard bore can operate as a cable guide, and can include a rounded opening to minimize abrasion to a cable moving through it. A ceramic element can be included in the bore to minimize abrasion to the cable.
摘要翻译：提供了一种射箭弓，其包括电缆护套和/或电缆引导件，其可以弯曲以选择性地相对于弓的弓弦行进的平面移动电缆，以最小化凸轮偏心，肢体扭曲和/或电缆磨损。在弓弦被释放之后，电缆护套和/或引导件可以沿着弓弦被拉动并远离弓弦平面移动到弓弦平面，从弓弦和任何附加箭头的方式移开。电缆护套可以限定一个孔，例如一个细长的孔，当弓弦未被拉伸时，其沿着大致平行于弓弦的轴线延伸穿过该孔。电缆保护孔可以作为电缆引导件操作，并且可以包括圆形开口，以最小化对通过它的电缆的磨损。孔中可以包含一个陶瓷元件，以最大程度减少对电缆的磨损。
