摘要:
An expandable arrowhead having a blade-carrying body with a slot that houses at least one movably mounted blade. Each blade can be pivotally mounted about a shaft. In some embodiments, the shaft is fixed with respect to the body. In other embodiments, the shaft is movably mounted with respect to the body, for example by mounting a shaft within the slot so that the shaft moves within the slot with respect to the blade-carrying body. In some embodiments of this invention, a spring element positively holds one or more blades in a closed position or a retracted position, particularly during extreme forces encountered when launching an arrow from an archery bow, such as a compound archery bow. The spring element of this invention can be used to improve blade opening capabilities of conventional blade-opening arrowheads or broadheads.
摘要:
An arrow rest for supporting an arrow shaft with respect to an archery bow. A support element is moveably mounted between a first position or a load position and a second position or a launch position. In the launch position, the arrow shaft can be forced into, such as by the forces of gravity, a centered location or a preferred shooting position.

A release device with a follow-through or recoil motion for use with mechanically launched projectiles. A recoil motion is in a direction opposite the path of the projectile. Releasing an arrow from a bow provides correct form and follow-through motion of a user hand directly opposite to a direction of a path of the launched arrow, to improve flight accuracy. The release device includes a housing, a trigger, a keeper and a recoil assembly. This invention also relates to a method of using the release device.

A rotatable arrowhead having a blade-carrying body that rotates with respect to a shaft that is attached with respect to an arrow shaft. In one embodiment, the rotatable arrowhead has a body and a tip portion that preferably rotate together with respect to the shaft of the arrowhead. The shaft extends within a through bore of the body. A portion of the shaft has a peripheral retention groove about at least a portion of a periphery of the shaft. The tip portion accommodates a retainer. In an assembled condition of the arrowhead, the retainer is positioned within the retention groove. In another embodiment, the rotatable arrowhead has a body that rotates with respect to the shaft of the arrowhead. The shaft extends within the through bore of the body, either partially or completely. The retainer can be mounted within the body or the tip portion, depending upon whether or not the tip portion rotates with respect to the body.
摘要:
An arrow rest rotatably having an arrow support movably mounted with respect to an archery bow. The arrow support can be simultaneously urged in one direction away from an arrow shaft during launch of the arrow shaft, and another portion of the arrow support can be urged in a second direction, toward the arrow shaft. The arrow rest of this invention can be used to accommodate or overcome a spined or bent arrow shaft, such as during initial launch of an arrow from an archery bow.
摘要:
An arrow rest including a magnetic ring mounted with respect to an archery bow. The magnetic ring includes an inner surface that defines an arrow shaft passage and an outer surface. The magnetic ring produces a first magnetic field about the arrow shaft passage. The magnetic ring forms an opening between the inner surface and the outer surface, and a shaft of an archery arrow is passable through the opening to position the arrow shaft within the arrow shaft passage. The archery arrow is movable between a loading position and a drawn position. In the drawn position, the first magnetic field interacts with a second magnetic field produced by a second magnet mounted at a tip portion of the archery arrow to suspend a portion of the arrow shaft within the arrow shaft passage.
摘要:
An arrow rest preferably having three or more flanges that extend outward in a generally radial direction. The flanges are peripherally spaced with respect to each other and form a clearance cutout between flange surfaces that face or oppose each other. The flanges or another suitably shaped body form two or more clearance cutouts that each accommodate a different diameter of a differently sized arrow shaft.
摘要:
A mounting apparatus having a rod slidably mounted within a longitudinal bore of a housing. The rod has returnable pivoting action and adjustable, returnable plunger action, with respect to the housing. A compression spring is used to return the rod to a linear rest position after linear displacement of the rod with respect to the housing. A lock nut having a through bore is used to access a tension adjustment screw which varies the length of the compression spring.
摘要:
A method for attaching a vane with respect to a shaft of an arrow or a crossbow bolt. The vane is attached to a tube or sleeve that is positionable over an outer surface of the shaft. The sleeve has an inner surface and the shaft has an outer surface. In an attached position of the vane with respect to the shaft, an adhesive is sprayed onto the inner surface or is otherwise positioned between and contacts at least a portion of the inner surface of the sleeve and at least a portion of the outer surface of the shaft.
